Upon request, Sellers or Buyer, as the case may be, will make available for review, during normal business hours, the relevant vendor or other invoices supporting their request for reimbursement, together with proof of their payment thereof.

(e) Property Costs that are paid periodically shall be prorated based on the number of days in the applicable period falling before, and the number of days in the applicable period falling on or after, the Effective Time. In each case, Buyer shall be responsible for the portion allocated to the period on and after the Effective Time and Sellers shall be responsible for the portion allocated to the period before the Effective Time. Notwithstanding the foregoing, for the avoidance of doubt, Buyer shall not be obligated to reimburse Sellers for any payment of delayed rental, shut-in royalties and other lease-maintenance costs incurred or paid prior to the Effective Time.

(v) to the extent that Sellers are underproduced or underdelivering as of the Effective Time as shown with respect to the net Imbalances set forth in Schedule 4.18, as complete and final settlement of all such Imbalances, the amount of the Imbalances as of the Effective Time multiplied by a realized price during the period such Imbalance accrued on a per MMBtu basis; and

(vi) any other amount paid by Buyer under Section 8.1, agreed upon by Sellers and Buyer in writing or finally resolved pursuant to Section 3.7, Section 10.2 or Section 10.4.

(b) The Purchase Price shall be adjusted downward by the following amounts:

(i) an amount equal to all Property Costs that are incurred prior to the Effective Time but paid by Buyer (as is consistent with Section 2.4(a) and Section 2.4(b)), but excluding any amounts previously reimbursed to Buyer pursuant to Section 2.4(d);

(ii) an amount equal to the sum of, to the extent that such amounts have been received by Sellers and not remitted or paid to Buyer, (A) all proceeds from the production of Hydrocarbons from or attributable to the Leases, Units and ▇▇▇▇▇ that are attributable to the time period from and after the Effective Time, (B) all other income, proceeds, receipts and credits earned with respect to the Assets that are attributable to the time period from and after the Effective Time, (C) all proceeds from the sale of Hydrocarbons described in Section 2.1(l)) and (D) any other amounts to which Buyer is entitled pursuant to Section 2.4(a);

(iii) the sum of all properly asserted and unwaived Title Defect Amounts determined in accordance with Section 10.1 (including, for the avoidance doubt, any Title Defect properly asserted under Section 10.6);

(v) the Allocated Value of the Assets excluded from the transactions contemplated hereby pursuant to Section 6.4(b), Section 6.5(c), Section 10.3(b), Section 10.5(a)(i), Section 10.5(b)(i) or Section 10.6;

(vi) the amount of all Asset Taxes allocated to Sellers in accordance with Section 13.1 but paid or otherwise economically borne by Buyer;

(vii) to the extent that Sellers are overproduced or overdelivering as of the Effective Time as shown with respect to the net Imbalances set forth in Schedule 4.18, as complete and final settlement of all such Imbalances, the amount of the Imbalances as of the Effective Time multiplied by a realized price during the period such Imbalance accrued on a per MMBtu basis;

(viii) an amount equal to those proceeds from the sale of Hydrocarbons attributable to the Assets and payable to owners of working interests, royalties, overriding royalties and other similar interests that (1) are held in suspense by Sellers, or (2) are received by Sellers from oil and gas purchasers and not distributed;

(ix) an amount equal to all sums paid to Sellers by Third Parties by reason of an individual Casualty Loss pursuant to Section 6.4 to the extent such sums have not been used to repair or restore any Assets adversely affected by any Casualty Loss in accordance with Section 6.4(a)(i);

(x) an amount equal to all sums required to satisfy any Liabilities arising from any Third Party Claims attributable to obligations of Sellers or their respective Affiliates to execute and deliver assignments of any interest in the Assets to any Person that would cause Sellers’ title to any Asset to be less than Defensible Title; provided such Third Party Claims are not Excluded Assets and all amounts are specifically identified in each instance and are accompanied with supporting documentation of such Third Party Claims; and

(xi) any other amount agreed upon by Sellers and Buyer in writing or finally resolved pursuant to Section 3.7, Section 10.2 or Section 10.4.

3.4 Preliminary Settlement Statement. Not later than November 27, 2017 (or, if Buyer exercises its right to extend the Target Closing Date under Section 8.1, December 13, 2017) prior to Closing, Sellers shall prepare and deliver to Buyer, using and based upon the best information available to Sellers, a closing statement estimating the Purchase Price after giving effect to all adjustments to the Purchase Price set forth in Section 3.3, setting forth each adjustment to the Purchase Price it anticipates to be appropriate as of the Closing Date necessary to determine the Adjusted Purchase Price (as of the Closing Date) and providing supporting documentation showing the calculation of such adjustments in accordance with Article III (the “Preliminary Settlement Statement”). The Preliminary Settlement Statement shall also include wire instructions for each account receiving a portion of the Closing Cash Payment and the amount to be wired to each such account. Buyer will have three (3) Business Days after receipt of the Preliminary Settlement Statement to review such statement and to provide written notice to Sellers of Buyer’s objection to any item on the statement. Buyer’s notice shall clearly identify the item(s) objected to and the reasons and support for the objection(s). The Parties shall attempt

to agree on the amount of the Adjusted Purchase Price to be paid at the Closing no later than one (1) Business Day before Closing. If the Parties do not agree by that date, Seller’s good faith estimate shall be used to determine the adjustments to the Purchase Price at Closing, subject to further adjustments as set forth in Section 3.5.

3.5 Final Settlement Statement. On or before 120 days after Closing (the “Final Settlement Date”), a final settlement statement (the “Final Settlement Statement”) will be prepared by Buyer, based on actual income and expenses and which takes into account all final adjustments made to the Purchase Price, excluding all Title Defect and related title issues subject to pending dispute under Section 10.2, and shows the resulting final Purchase Price (the “Final Price”). The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within thirty (30) days, after receipt of the Final Settlement Statement, Whitehorse, on behalf of the Whitehorse Sellers, and Siltstone II, on behalf of the Siltstone Sellers, shall return to Buyer a joint written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Any changes not so specified in the Dispute Notice shall be deemed waived and Buyer’s determinations with respect to all such elements of the Final Settlement Statement that are not addressed specifically in the Dispute Notice shall prevail. If Whitehorse and Siltstone II fail to timely deliver a Dispute Notice to Buyer containing changes Sellers propose to be made to the Final Settlement Statement, the Final Settlement Statement as delivered by Buyer will be deemed to be correct and will be final and binding on all Parties and not subject to further audit or arbitration. If the Final Price set forth in the Final Settlement Statement is mutually agreed upon by Sellers and Buyer, the Final Settlement Statement and the Final Price shall be final and binding on the Parties (other than with respect to amounts not accounted for therein or settled thereby). Within ten (10) days after the earlier of (a) the expiration of Sellers’ thirty (30)-day review period without delivery of any written report or (b) the date on which the Parties finally determine the Final Price or the Accounting Arbitrator finally determines the disputed matters, as applicable, (i) Buyer shall pay to Sellers the amount by which the Final Price exceeds the Closing Cash Payment, or (ii) Sellers shall pay to Buyer the amount by which the Closing Cash Payment exceeds the Final Price; provided that, if applicable, any amount payable by one Party to the other under this Section 3.5 shall first be satisfied out of the portion of the Defect Escrow Amount the owning Party is entitled to at such time, and then, if applicable, the owning Party shall pay to the owed Party any outstanding amounts. All amounts paid pursuant to this Agreement shall be delivered in United States currency by wire transfer of immediately available funds to the account specified in writing by the relevant Party.

3.6 Defect Escrow. At the Closing, if applicable, Buyer shall deposit into the Escrow Account an amount equal to the aggregate amounts escrowed pursuant to Sections 10.1(b), 10.2 and Section 10.6 (such amount, the “Defect Escrow Amount”). Any Defect Escrow Amount not released under Section 3.5 shall be released to the Party entitled to such amount at the earlier of: (i) the end of the Cure Period in accordance with Section 10.1(b), or (ii) upon final resolution of any disputed Title Defect pursuant to Section 10.2 or any disputed Environmental Defect pursuant to Section 10.6, as applicable, and the Parties shall jointly instruct the Escrow Agent accordingly.

3.7 Accounting Disputes. If Whitehorse, on behalf of the Whitehorse Sellers, Siltstone II, on behalf of the Siltstone Sellers and Buyer are unable to resolve the matters addressed in the Dispute Notice within thirty (30) days after the delivery of the Dispute Notice, then either Party may initiate the arbitration process set forth in this Section 3.7 by sending a written notice to the other Party (the “Arbitration Notice”).

ARTICLE VI

CERTAIN AGREEMENTS

6.1 Non-Competition.

(a) As a material inducement for Buyer to enter into and close this Agreement, and in order to protect the goodwill and value of the Assets that are conveyed by Sellers hereunder, each Seller agrees to the restrictions set forth in this Section 6.1. Except as permitted under Section 10.6, from and after Closing until the date that is 18 months after the Closing Date (the “Restricted Period”), Sellers shall not (and each Seller shall cause their respective Affiliates having access to information and data relating to the Assets, this Agreement or the transactions contemplated hereunder to not), directly or indirectly, (i) purchase, acquire, or earn (or purchase or acquire the right to purchase, acquire or earn) any Hydrocarbon leases, Hydrocarbon interests, royalty interest, overriding royalty interests, Hydrocarbon interests payable out of production, production payments or any other contractual rights to acquire any of the foregoing interests covering the Designated Area (such purchase, acquisition, or earning, a “Prohibited Transaction”), or (ii) encourage, facilitate, solicit,

initiate or participate in discussions or negotiations with, or provide any information to, any existing co-working interest owner of the Assets, with respect to a Prohibited Transaction. Without limiting the foregoing, except as permitted under Section 10.6, each Seller hereby agrees to immediately cease (and to cause its Affiliates to cease) any and all discussions, negotiations or other activities related to such purchase, acquisition, or earn-out to the extent such discussions, negotiations or other activities are occurring or have occurred on or prior to the date hereof. Each Seller, on behalf of itself and its Affiliates, hereby waives and disclaims any preferential purchase right, right of first refusal, or other similar rights and any applicable consents that it may have and that may be applicable to any transaction in which Buyer purchases, acquires, or earns (or purchases or acquires the right to purchase, acquire or earn) any Hydrocarbon leases, Hydrocarbon interests, royalty interest, overriding royalty interests, Hydrocarbon interests payable out of production, production payments or any other contractual rights to acquire any of the foregoing interests covering any portion of the lands within the Designated Area.

(b) Sellers shall not (and each Seller shall cause their respective Affiliates to not),

(i) during the Restricted Period and solely with respect to Sellers and their respective Affiliates having access to information and data relating to the Assets, this Agreement or the transactions contemplated hereunder, obtain any oil and gas leases or otherwise top lease from the lessor(s) of the Leases covering all or a portion of the lands covered by the Leases which may expire within six (6) months after the Restricted Period; or

(ii) sell, assign, convey, transfer or otherwise dispose of or disclose to any Third Party, any Records;

provided, however, that the foregoing shall not restrict disclosures that are required (upon advice of counsel) by applicable securities or other Laws or regulations or the applicable rules of any stock exchange having jurisdiction over Sellers or their respective Affiliates.

(c) Each Seller acknowledges and agrees that the geographic scope, scope of activity restrictions, and duration of the covenants contained in this Section 6.1 are the result of arm’s-length bargaining and are fair and reasonable in all respects. It is the desire and intent of the Parties that the provisions of this Section 6.1 (and each portion thereof) be enforced to the fullest extent permitted under applicable Law. Sellers acknowledge that this Section 6.1 is enforceable in all respects; nonetheless, if any of the restrictions of this Section 6.1 (or any portions thereof) are found by an arbitrator or court of competent jurisdiction to be unreasonable, overly broad, or otherwise unenforceable, the Parties intend that such restrictions (and portions thereof) shall not be thereby terminated but shall be modified by such arbitrator or court so as to be valid and enforceable and, as so modified, to be fully enforced. Each Party further acknowledges that a breach or threatened breach of this Section 6.1 would cause irreparable harm to Buyer for which it would have no adequate remedy at Law, that it would be impractical to determine Buyer’s and its Affiliates’ damages in the event of a breach or threatened breach, and that Buyer and its Affiliates shall be entitled to immediate injunctive relief and specific performance as remedies for any such breach. Such remedies shall not be the exclusive remedies for a breach or threatened breach of this Section 6.1 but shall be in addition to all other remedies available at law and equity, including the recovery of damages.

(a) If, after the Execution Date, but prior to the Closing Date, any portion of the Assets is damaged, destroyed or made unavailable or unusable for the intended purpose by fire or other casualty or is taken in condemnation or under right of eminent domain (each a “Casualty Loss”), and the Aggregate Defect Amount is greater than twenty percent (20%) of the unadjusted Purchase Price, Buyer may elect to terminate this Agreement at any time prior to Closing pursuant to Section 11.1(e). In the event that Buyer does not elect to terminate this Agreement pursuant to Section 11.1(e), Buyer shall elect by written notice to Sellers prior to Closing either (i) to cause the Assets adversely affected by any such individual Casualty Loss to be repaired or restored to at least their condition prior to such Casualty Loss, at Sellers’ sole cost and expense, prior to the Closing Date or (ii) for the Purchase Price to be reduced by the sums of all amounts paid to Sellers by Third Parties by reason of such Casualty Loss that have not been used to repair or restore any Assets adversely affected by any Casualty Loss in accordance with Section 6.4(a)(i), and Sellers shall assign, transfer and set over to Buyer or subrogate Buyer to all of Sellers’ right, title and interest (if any) in unpaid awards, condemnation payments, insurance proceeds and other rights and claims against Third Parties (other than Persons within the Seller Indemnified Parties) arising out of the Casualty Loss.

6.5 Access.

(a) From the Execution Date to the Closing Date (the “Examination Period”), Sellers will give Buyer, at Buyer’s sole cost, risk and expense, reasonable access to Sellers’ office and personnel, the Assets and the Records (and the right to copy Records) for the purpose of conducting such reasonable and ordinary examinations as Buyer may in its sole

discretion choose to conduct with respect to the Assets. Sellers will use commercially reasonable efforts (without the obligation to incur any out-of-pocket costs or expenses (unless Buyer agrees to make such payment)) to obtain waivers from the applicable Third Parties to be able to disclose to Buyer, as soon as reasonably practicable after the Execution Date, all information relating to the Assets that Sellers are restricted from disclosing as a result of confidentiality arrangements under any agreement with Third Parties.

(b) The access granted to Buyer under this Section 6.5 shall be limited to Sellers’ normal business hours, and Buyer’s investigation shall be conducted in a manner that minimizes interference with the operation of the Assets.

Buyer shall not operate any equipment or conduct any testing or sampling of soil, groundwater or other materials (including any testing or sampling for Hazardous Substances, Hydrocarbons or NORM) (“Phase II Activity”). Notwithstanding the foregoing, if following the conduct of the Phase I Environmental Site Assessment, Buyer reasonably believes that any Phase II Activity is necessary for it to conduct its due diligence investigation of any of the Assets in order to determine the existence and/or magnitude of an Environmental Defect, Buyer shall furnish to Sellers for review a proposed scope of such Phase II Activity, including a reasonable description of such activity and a description of the approximate locations of any sampling to be conducted. Following the receipt and review of such proposal by Sellers, Sellers shall elect, in its sole discretion, promptly but in any event within 5 days of receipt of such proposal, to permit or refuse to permit the conduct of any Phase II Activity by Buyer; provided, however, that if Sellers refuse to permit the conduct of the Phase II Activity, then the Assets with respect to which Buyer requested permission to conduct such Phase II Activity may, at Buyer’s sole option, be excluded from the Assets to be conveyed to Buyer at Closing and the unadjusted Purchase Price shall be adjusted downward by the Allocated Value of such Property in accordance with Section 3.3(b)(v).

If such Seller or such Affiliates (or other Persons acting for or on its behalf) receives from any Person any offer, inquiry or other informational request referred to above, such Seller will promptly advise such Person, by written notice, of the terms of this provision and will promptly, orally and in writing, advise Buyer of such offer, inquiry or request and deliver a copy to Buyer of any such written offer, inquiry, or request;

If requested by the Auditor in connection with the audit of the foregoing financial statements or its review of unaudited quarterly or interim financial statements described above, Sellers shall, and shall cause its respective Affiliates and its and their officers and employees to, execute and deliver to the Auditor such representation letters, in form and substance customary for representation letters provided to external audit firms by management of the company whose financial statements are the subject of an audit or are the subject of a review pursuant to Statement of Auditing Standards 100 (Interim Financial Information), as may be reasonably requested by the Auditor, with respect to the foregoing financial statements; provided, however, that Buyer shall provide customary indemnity for any such officer or employee executing and delivering such representation letters to the Auditor.

To the extent statements of revenues and direct operating expenses are provided, Sellers shall provide suitable electronic detail in the form of lease operating statements by property adequately supporting all statements provided.

(ii) Promptly following the date of any written request made by Buyer pursuant to Section 6.11(b)(i), Sellers shall request the Auditor, after discussing specifications with Buyer, to (A) perform an audit of the of the foregoing financial statements on Buyer’s behalf and to issue its opinion with respect to the Audited Financial Statements, (B) provide a review of unaudited quarterly or interim financial statements for periods prior to or including the Closing Date in accordance with Statement of Auditing Standards 100 (Interim Financial Information), (C) provide its written consent for the use of its audit reports with respect to Audited Financial Statements in any current or future SEC Filings filed by Resources, its Affiliates, or their respective successors and assigns, and (D) conduct such other procedures as are reasonably necessary or appropriate for the Auditor to provide the foregoing.

In this regard, Sellers shall, and shall cause its respective Affiliates and its and their officers and employees to, make accounting and field records available to the Auditor during reasonable business hours to complete any such audit and interim period review. To the extent required by the Auditor, Sellers shall, and shall cause its respective Affiliates and its and their officers and employees to, provide such reasonable further cooperation, including by providing such additional management letters of representation, as may be reasonably requested by the Auditor, in order for the Auditor to provide any further written consents to the inclusion or incorporation by reference of the Audited Financial Statements in any future SEC Filings of Resources, its Affiliates, or their respective successors and assigns. Buyer shall bear all fees charged by the Auditor following the initial delivery of the financial statements set forth in this Section 6.11(b).

(c) Notwithstanding anything to the contrary contained in this Agreement (including this Section 6.11): (i) nothing in this Agreement (including this Section 6.11) shall require any such cooperation to the extent that it would (A) require Sellers to pay any commitment or other fees, reimburse any expenses or otherwise incur any liabilities or give any indemnities prior to the Closing, (B) unreasonably interfere with the ongoing business or operations of Sellers, or (C) require Sellers to enter into or approve any agreement or other documentation effective prior to the Closing and (ii) no action, liability or obligation (including any obligation to pay any commitment or other fees or reimburse any expenses) of Sellers or any of its representatives under any certificate, agreement, arrangement, document or instrument relating to the Financing shall be effective until the Closing.

(a) With respect to any oil, gas and/or mineral lease located within the geographical area described on Annex II but outside of the Designated Area and that is either owned by any Seller or its Affiliates as of the Execution Date or acquired or subject to control by a Seller or its Affiliates during the period starting on the Execution Date and ending on the last day of the Cure Period (each such oil and gas lease, a “ROFO Property”), any time after the Execution Date but prior to the last day of the Cure Period, such Seller shall provide Buyer with a written notice (“ROFO Notice”) identifying the ROFO Property (the “Offered Interest”). The ROFO Notice will constitute a binding offer (the “ROFO Offer”) by such Seller to Transfer to Buyer the Offered Interest at a price not more than Seventeen Thousand Dollars ($17,000) per Net Mineral Acre (proportionally reduced to such Seller’s Working Interest) and upon the same terms and conditions set forth under this Agreement and such offer will be irrevocable for a period ending on the later of (i) ten (10) days following receipt by Buyer and (ii) the Closing Date (such period, the “ROFO Period”). At any time on or before the end of the ROFO Period, Buyer will have the right but not the obligation to elect to accept such ROFO Offer by written notice to such Seller and acquire all but not less than all of the Offered Interest on the same terms and conditions set forth under this Agreement. The failure by Buyer to so notify the offering Seller on or before the end of the ROFO Period will be deemed an election by Buyer not to acquire such Offered Interest and Sellers will be free to transfer ROFO Property without restriction.

(b) If Buyer elects to acquire the Offered Interest, then such notice to the offering Seller shall constitute a binding acceptance to such the offering Seller’s ROFO Offer and each of the offering Seller and Buyer shall use commercially reasonable efforts to cooperate together to consummate the Transfer of the Offered Interest to Buyer as promptly as practicable following such acceptance; provided that all terms and condition of this Agreement shall apply mutatis mutandis to such Transfer as if the “Execution Date” of the agreement for such Transfer is the date of Buyer’s acceptance of the applicable ROFO Offer and the “Effective Time” is the later of the effective date of the applicable ROFO Property and the Effective Time hereunder.

TITLE MATTERS, ENVIRONMENTAL MATTERS AND OTHER PURCHASE PRICE ADJUSTMENTS

10.1 Title Defects.

(a) On or before 5:00 pm Central Time on the date that is thirty (30) days after the Execution Date (the “Defect Claim Date”), Buyer may deliver claim notices meeting the requirements of this Section 10.1(a) (collectively, the “Title Defect Notices” and, individually, a “Title Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Section 10.1(a). For all purposes of this Agreement and except for Sellers’ special warranty of title set forth in the Assignment, Buyer shall be deemed to have waived, and Sellers shall have no liability for, any claim of Title Defect pursuant to this Section 10.1 which Buyer fails to assert as a Title Defect by a Title Defect Notice received by Sellers on or before the Defect Claim Date. Each Title Defect Notice shall be in writing, and shall include (i) a description of the alleged Title Defect(s) and the Asset(s), or portions thereof, affected by such Title Defect (each a “Title Defect Property”), (ii) the Allocated Value of each Title Defect Property, (iii) supporting documents reasonably necessary for Sellers to verify the existence of such Title Defect(s) and (iv) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by such Title Defect(s); provided, that substantial compliance with clause (iii) by the Defect Claim Date followed by prompt delivery of any remaining materials shall satisfy clause (iii). To give Sellers an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use commercially reasonable efforts to give Sellers, on or before the end of each calendar week prior to the Defect Claim Date, a written notice of all Title Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented and/or amended prior to the Defect Claim Date.

(b) Sellers shall have the right, but not the obligation, upon delivering written notice to Buyer on or prior to the date that is within three days following the Defect Claim Date, to attempt, at Sellers’ sole cost, to cure or remove any Title Defects (of which Sellers have been advised by Buyer) on or before the expiration of ninety (90) days counted from and after the Closing Date (the “Cure Period”), unless the Parties otherwise agree. If Sellers have provided notice within three (3) days following the Defect Claim Date of Sellers’ intent to attempt to cure a Title Defect within the Cure Period, there shall be no reduction to the Purchase Price with respect to the Title Defect for purposes of Closing and the applicable Title Defect Property shall be assigned to Buyer at Closing, but, solely with respect to those Title Defects for which Sellers have elected to cure, Buyer shall instead deposit into the Escrow Account the amount of the aggregate amount of such Title Defect Amounts for which Sellers have elected to cure and upon satisfactory cure of such Title Defect, or if it is determined by the Title Arbitrator that such Title Defect has been cured then Sellers shall be entitled to a release from the Escrow Account of an

amount that is equal to the amount Sellers are entitled to pursuant to this Section 10.1 after taking into account any adjustment to the Purchase Price that may be required hereunder. If at the end of the Cure Period the Title Defect is not cured as agreed by Sellers and Buyer or if Sellers and Buyer cannot agree, and it is determined by the Title Arbitrator that such Title Defect is not cured at the end of the Cure Period, then in either case Buyer shall be entitled to a release from the Escrow Account of an amount that is equal to the amount Buyer is entitled to pursuant to this Section 10.1 which, with respect to any Title Defect determined in Sellers’ favor, shall in no event be more than the Title Defect Amount claimed by Sellers for such Title Defect in the applicable Title Defect Notice.

(c) In the event that (i) any Title Defect asserted by Buyer in accordance with Section 10.1(a) is not waived by Buyer and (ii) Sellers have not provided notice to Buyer at or prior to the date that is three (3) days following the Defect Claim Date of Sellers’ intent to attempt to cure the given Title Defect, or Sellers have provided such notice but the Title Defect is not cured before the expiration of the Cure Period, then the Parties shall make a downward adjustment to the Purchase Price by an amount equal to an amount determined pursuant to Section 10.1(d) or Section 10.2, as applicable, as being the value of such Title Defect (the “Title Defect Amount”). For the avoidance of doubt, the amount by which the Purchase Price is reduced by multiple Title Defects affecting a single Title Defect Property shall be determined based on the aggregate amount of Title Defect Amounts of all Title Defects affecting such Title Defect Property on a Title Defect Property by Title Defect Property basis.

(d) The Title Defect Amount with respect to an affected Title Defect Property resulting from a Title Defect shall be the amount by which the Allocated Value of such Title Defect Property is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following methodology, terms and conditions:

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

(ii) if the Title Defect with respect to such Title Defect Property is a lien, encumbrance or other charge which 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 affected Title Defect Property;

(iii) if the Title Defect with respect to such Title Defect Property reflects a positive discrepancy between (A) the Minimum Net Revenue Interest and (B) the actual Net Revenue Interest for such Title Defect Property that is a Lease or a Fee Mineral, and the Working Interest of Sellers for such Title Defect Property is reduced proportionately below that shown in Exhibit A-1 or in Exhibit A-3 (as applicable), then the Title Defect Amount shall be the product of (I) Sellers’ actual Net Mineral Acres of such Title Defect Property times $17,000, multiplied by (II) a fraction, the numerator of which is the amount of the Net Revenue Interest decrease and the denominator of which is the Minimum Net Revenue Interest; provided, however, that if the Net Revenue Interest for such Title Defect Property is lower than 65% (except with respect to Leases labeled with lease numbers, TX371038001 and TX371038002 on Exhibit A-1, 56.25%) (proportionately reduced to Sellers’ combined Working Interest), then the Title Defect Amount for such Title Defect shall equal to the Allocated Value of such Title Defect Property;

(iv) if the Title Defect with respect to such Title Defect Property which is a Well reflects a positive discrepancy between (A) the Net Revenue Interest stated for such Well in Exhibit A-2 and (B) the actual Net Revenue Interest of such Well, and the Working Interest of Sellers for such Well is reduced proportionately below that shown in Exhibit A-2, then the Title Defect Amount shall be the product of the Allocated Value of such Well multiplied by a fraction, the numerator of which is the amount of the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest stated in Exhibit A-2;

(v) if the Title Defect with respect to such Title Defect Property represents a positive discrepancy between (A) the Net Mineral Acres stated for such Title Defect Property that is a Lease or a Fee Mineral on Exhibit A-1 or Exhibit A-3 (as applicable) and (B) the actual Net Mineral Acres that such Title Defect Property covers after taking into account the Title Defect, then the Title Defect Amount of such Title Defect shall be calculated by multiplying Seventeen Thousand Dollars ($17,000) per Net Mineral Acre by the positive amount resulting from subtracting the actual Net Mineral Acres covered by such Title Defect Property from the Net Mineral Acres designated for such Title Defect Property on Exhibit A-1 or Exhibit A-3 (as applicable);

(vi) if the Title Defect with respect to such Title Defect Property represents an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property of a type not described in clauses (i), (ii), (iii), or (v) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property adversely 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 Sellers and such other factors as are necessary to make a proper evaluation;

(vii) 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, or for which Buyer otherwise receives credit in the calculation of the Adjusted Purchase Price; and

(viii) notwithstanding anything to the contrary in this Article X, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property (except for those Title Defects described under Section 10.1(d)(ii)) shall not exceed the Allocated Value of such Title Defect Property.

(e) Notwithstanding anything herein to the contrary, with respect to (and solely with respect to) a Title Defect Property that is a Well, but except for Title Defects that would constitute a breach of the special warranty of title set forth in the Assignment or that Buyer may assert with respect to any Additional Interest (which Title Defects and associated Title Defect Amounts shall not be limited by this Section 10.1(e)), (1) in no event shall there be any adjustments to the Purchase Price under this Section 10.1 for Title Defects affecting an individual Well for which the aggregate Title Defect Amounts for such Well does not exceed

$50,000.00 (the “Individual Title Defect Threshold”) and (2) in no event shall there be any adjustment to the Purchase Price under this Section 10.1 for Title Defects affecting an individual Well for which the aggregate Title Defect Amounts for such Well exceeds the Individual Title Defect Threshold unless the amount of the aggregate Title Defect Amounts for all ▇▇▇▇▇ that exceed the Individual Title Defect Threshold exceeds a deductible in the amount of three and one-half percent (3.5%) of the unadjusted Purchase Price (the “Title Defect Deductible”), after which point Buyer shall be entitled to adjustments to the Purchase Price hereunder, but only to the extent of the amount by which the aggregate amount of such Title Defect Amounts exceeds the Title Defect Deductible.

10.2 Title Dispute Resolution. Whitehorse, on behalf of the Whitehorse Sellers, Siltstone II, on behalf of the Siltstone Sellers, and Buyer shall attempt to agree on all Title Defects and Title Defect Amounts prior to the Closing. If Whitehorse, on behalf of the Whitehorse Sellers, Siltstone II, on behalf of the Siltstone Sellers, and Buyer are unable to agree by the Closing, then subject to Section 10.1(b), the Parties shall (i) exchange their final proposed Title Defect Amounts of such Title Defects and (ii) proceed to Closing on the Assets subject to such Title Defects and Buyer shall pay the amount of the Title Defect Amounts as set forth in Buyer’s final proposed Title Defect Amounts of such Title Defects then in dispute into the Escrow Account and all Title Defects and Title Defect Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 10.2. Likewise, if Sellers have provided notice at or prior to the date that is three (3) days following the Defect Claim Date of Sellers’ intent to attempt to cure a Title Defect and by the end of the Cure Period, Whitehorse, on behalf of the Whitehorse Sellers, Siltstone II, on behalf of the Siltstone Sellers, and Buyer have been unable to agree upon whether such Title Defects have been cured, or Sellers have failed to cure any Title Defects which Sellers provided notice that Sellers would attempt to cure and Whitehorse, on behalf of the Whitehorse Sellers, Siltstone II, on behalf of the Siltstone Sellers, and Buyer have been unable to agree on the Title Defect Amounts for such Title Defects, then the cure and/or Title Defect Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 10.2. There shall be a single arbitrator, who shall be a title attorney with at least 10 years’ experience in oil and gas titles involving properties in the regional area in which the Title Defect Properties are located and shall not have worked as an employee or outside counsel for any Party or its Affiliates during the five (5) year period preceding the arbitration or have any financial interest in the dispute, as selected by mutual agreement of Buyer, on the one hand, and Whitehorse (on behalf of the Whitehorse Sellers) and Siltstone II (on behalf of the Siltstone Sellers), jointly, on the other hand, within fifteen (15) days after the end of the Cure Period (or such other time as mutually agreed), and absent such agreement, by the Houston, Texas office of the American Arbitration Association (the “Title Arbitrator”). The arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 10.2. Each of Buyer, on the one hand, and Whitehorse (on behalf of the Whitehorse Sellers) and Siltstone II (on behalf of the Siltstone Sellers), jointly, on the other hand, shall submit their respective positions and evidence to the Title Arbitrator within fifteen (15) days after selection of the Title Arbitrator. The Title Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal, and shall be limited to awarding only Whitehorse and Siltstone II’s joint or Buyer’s final proposed Title Defect Amount exchanged by the Parties as provided above. The Title Arbitrator shall make a separate determination with

respect to the existence of each asserted Title Defect. In making his or her determination, the Title Arbitrator shall be bound by the relevant rules set forth in this Article X 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 shall act as an expert for the limited purpose of determining the specific disputed Title Defect and/or Title Defect Amount submitted by either Buyer or Whitehorse (on behalf of the Whitehorse Sellers) and Siltstone II (on behalf of the Siltstone Sellers) jointly, and may not award damages, interest or penalties to either Party with respect to any matter, but shall award to the prevailing Party its arbitration costs and attorneys’ fees. Sellers, jointly, on the one hand, and Buyer, on the other hand, shall each bear one-half of the costs and expenses of the Title Arbitrator. Within ten days after the Title Arbitrator delivers written notice to Buyer and Sellers of its award with respect to a Title Defect Amount related to a Title Defect, Buyer shall be entitled to withdraw from the Escrow Account the amount, if any, so awarded by the Title Arbitrator to Buyer plus all earnings thereof, with respect to any Title Defect resolved in Buyer’s favor, and the balance of the funds paid into the Escrow Account with respect to such Title Defects shall be paid to Sellers.

10.3 Environmental Defects.

(a) Buyer shall deliver to Whitehorse, on behalf of both Whitehorse and the Siltstone Sellers, no later than the Defect Claim Date, claim notices meeting the requirements of this Section 10.3(a) (collectively, the “Environmental Defect Notices” and, individually, an “Environmental Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Environmental Defects and which Buyer intends to assert as Environmental Defects pursuant to this Section 10.3. For all purposes of this Agreement and subject to Buyer’s remedy for a breach of the representations and warranties made by Sellers pursuant to Section 4.13 and Sellers’ indemnification obligations under Section 12.2, Buyer shall be deemed to have waived, and Sellers shall have no liability for, any Environmental Defect which Buyer fails to assert as an Environmental Defect by a properly delivered Environmental Defect Notice received by Sellers on or before the Defect Claim Date. Each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter constituting the alleged Environmental Condition (including the applicable Environmental Law violated or implicated thereby) and the Assets affected by such alleged Environmental Condition, (ii) the Allocated Value of the Asset(s) (or portions thereof) affected by such alleged Environmental Condition, (iii) supporting documents reasonably necessary for Sellers to verify the existence of such alleged Environmental Condition, and (iv) a calculation of the Remediation Amount that Buyer asserts is attributable to such alleged Environmental Defect; provided, that substantial compliance with clause (iii) by the Defect Claim Date followed by prompt delivery of any remaining materials shall satisfy clause (iii). To give Sellers an opportunity to commence reviewing and remediating Environmental Defects, Buyer agrees to use commercially reasonable efforts to give Sellers, on or before the end of each calendar week prior to the Defect Claim Date, a written notice of all Environmental Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented and/or amended prior to the Defect Claim Date. Sellers shall have the right, but not the obligation, to remediate, to the satisfaction of Buyer, any asserted Environmental Defect on or before Closing. If Sellers elect to remediate any Environmental Condition prior to Closing, Sellers shall implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that Sellers elect to undertake.

(b) In the event that any Environmental Defect timely asserted by Buyer in accordance with Section 10.3(a) is not waived in writing by Buyer or cured prior to the Closing Date, then at Closing Parties shall, at Buyer’s sole election, the following:

(i) reduce the Purchase Price by the Remediation Amount; or

(ii) in the case of Sellers-operated Assets, exclude the wellbore of the Asset that is subject to the Environmental Defect, from the transactions contemplated hereby, and transfer the remaining Asset (including the underlying Lease) to Buyer in which event, subject to Section 12.1(n), the Purchase Price shall not be reduced.

(c) Notwithstanding anything herein to the contrary, but except for Environmental Defects that Buyer asserts with respect to the Additional Interests (which Environmental Defects and associated Remediation Amounts shall not be limited by this Section 10.3(c)), (i) in no event shall there be any adjustments to the Purchase Price under this Section 10.3 for any individual Environmental Defect for which the Remediation Amount does not exceed $50,000.00 (the “Individual Environmental Defect Threshold”) and (ii) in no event shall there be any adjustment to the Purchase Price under this Section 10.3 for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Defect Threshold unless the amount of the aggregate Remediation Amounts of all Environmental Defects that exceed the Individual Environmental Threshold (but excluding any Remediation Amounts attributable to Assets subject to Environmental Defects that are excluded under Section 10.3(b)(ii)) exceeds a deductible in the amount of two percent (2.0%) of the unadjusted Purchase Price (the “Environmental Defect Deductible”), after which point Buyer shall be entitled to adjustments to the Purchase Price hereunder, but only to the extent of the amount by which the aggregate amount of such Remediation Amounts exceeds the Environmental Defect Deductible. With respect to any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Defect Threshold, for purposes of determining if the Environmental Defect Deductible has been satisfied and all other purposes herein, the Remediation Amount shall be the total amount for such Environmental Defect without giving effect to the Individual Environmental Defect Threshold.

10.4 Environmental Dispute Resolution. Whitehorse, on behalf of the Whitehorse Sellers, Siltstone II, on behalf of the Siltstone Sellers, and Buyer shall attempt to agree on all Environmental Defects and Remediation Amounts prior to Closing. If Whitehorse, on behalf of the Whitehorse Sellers, Siltstone II, on behalf of the Siltstone Sellers, and Buyer are unable to agree by Closing, subject to Buyer’s rights pursuant to Section 10.3(b)(ii), all affected Assets shall be conveyed to Buyer at Closing and Buyer shall pay the amount equal to Buyer’s estimate of the Remediation Amount attributable to such unresolved Environmental Defects claimed by Buyer into the Escrow Account and the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 10.4. There shall be a single arbitrator, who shall be an environmental attorney with at least fifteen (15) years’ experience in environmental matters involving oil and gas producing properties in the regional area in which the affected Assets are located and shall not have worked as an employee

or outside counsel for any Party or its Affiliates during the five (5) year period preceding the arbitration or have any financial interest in the dispute, as selected by mutual agreement of Buyer, on the one hand, and Whitehorse (on behalf of the Whitehorse Sellers) and Siltstone II (on behalf of the Siltstone Sellers), jointly, on the other hand, within fifteen (15) days after the Closing Date, and absent such agreement, by the Houston, Texas office of the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of Section 10.3. Each of Buyer, on the one hand, and Whitehorse (on behalf of the Whitehorse Sellers) and Siltstone II (on behalf of the Siltstone Sellers), jointly, on the other hand, shall submit their respective positions and evidence to the Environmental Arbitrator within fifteen (15) days after selection of the Environmental Arbitrator. The Environmental Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal. The Environmental Arbitrator shall make a separate determination with respect to the existence of each asserted Environmental Defect and/or Remediation Amount, and shall be limited to awarding only Whitehorse and Siltstone II’s joint or Buyer’s final proposed Remediation Amounts exchanged by the Parties as provided above. In making his or her determination, the Environmental Arbitrator shall be bound by the relevant rules set forth in this Article X 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 shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either Buyer or Whitehorse (on behalf of the Whitehorse Sellers) and Siltstone II (on behalf of the Siltstone Sellers) jointly, and may not award damages, interest or penalties to either Party with respect to any matter, but shall award to the prevailing Party its arbitration costs and attorneys’ fees. Sellers, jointly, on the one hand, and Buyer, on the other hand, shall each bear one-half of the costs and expenses of the Environmental Arbitrator. Within ten days of the final resolution of any dispute submitted to the Environmental Arbitrator, Buyer shall be entitled to withdraw from the Escrow Account the amount, if any, so awarded by the Environmental Arbitrator to Buyer plus all earnings thereof, with respect to any Environmental Defect resolved in Buyer’s favor and the balance of the escrow attributable to the resolved Environmental Defect shall be paid to Sellers.

10.5 Preferential Purchase Rights and Consents to Assign.

(a) With respect to each Preferential Purchase Right discovered prior to the Closing, Sellers, within five (5) Business Days after the discovery thereof, shall send to the holder of each such Preferential Purchase Right a notice in compliance with the contractual provisions applicable to such Preferential Purchase Right and requesting waivers of such rights. Sellers shall thereafter use commercially reasonable efforts to cause such waivers of Preferential Purchase Rights (or the exercise thereof) to be obtained and delivered prior to Closing.

(i) If, prior to Closing, any holder of a Preferential Purchase Right notifies Sellers that it intends to consummate the purchase of the Asset to which its Preferential Purchase Right applies or if the time for exercising such Preferential Purchase Right has not expired and Sellers have not received notice of an intent not to exercise or waiver of the Preferential Purchase Right, then the Asset(s) subject to such Preferential Purchase Right shall be

excluded from the Assets to be assigned to Buyer at Closing (but only to the extent of the portion of such Asset(s) affected by the Preferential Purchase Right), and the Purchase Price shall be reduced by the Allocated Value of the Asset(s) (or portion thereof) so excluded. If such holder of such Preferential Purchase Right thereafter fails to consummate the purchase of the Asset (or portion thereof) covered by such Preferential Purchase Right within the time frame specified in the Preferential Purchase Right, or the time for exercising such Preferential Purchase Right expires without exercise by the holder thereof (A) Sellers shall so notify Buyer and (B) Buyer shall purchase from Sellers, on or before ten (10) days following receipt of such notice, such Asset (or portion thereof) that was so excluded, under the terms of this Agreement and for a price equal to the amount by which the Purchase Price was reduced at Closing with respect to such excluded Asset (or portion thereof), subject to any adjustments as a result of any Title Defect asserted by Buyer in accordance with Section 10.1.

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

(b) With respect to each Consent (other than customary Post-Closing Consents), including those set forth in Schedule 4.4, Sellers, within ten (10) Business Days after the Execution Date, shall send to the holder of each such Consent a notice in compliance with the contractual provisions applicable to such Consent seeking such holder’s consent to the transactions contemplated hereby, and Sellers shall thereafter use its commercially reasonable efforts to obtain all such Consents prior to Closing.

(i) If (A) Sellers fail to obtain a Consent (other than customary Post-Closing Consents) prior to Closing and the failure to obtain such Consent would cause (1) the assignment of the Assets affected thereby to Buyer to be void or voidable, (2) the termination or other material impairment of an Asset under the express terms thereof or (3) the payment of liquidated damages, or (B) a Consent requested by Sellers is denied in writing (each such Consent, a “Required Consent”), then, in each case, (i) the Asset (or portion thereof) affected by such un-obtained Consent shall be excluded from the Assets to be assigned to Buyer at Closing, (ii) the Purchase Price shall be reduced by the Allocated Value of such Asset (or portion thereof) so excluded, (iii) Sellers shall hold such Asset or nominee for Buyer, effective as of the Effective Time and (iv) Sellers shall use reasonable commercial efforts to obtain such Consent or promptly as possible following Closing, but such reasonable commercial efforts shall not require Sellers or any of their respective Affiliates to make any out of pocket payments to counterparties. In the event that a Consent (with respect to an Asset excluded pursuant to this Section 10.5(b)(i)) that was not obtained prior to Closing is obtained as of the Final Settlement Date, then, (x) Buyer shall purchase the Asset (or portion thereof) that was so excluded as a result of such previously un-obtained Consent and pay to Sellers the amount by which the Purchase Price was reduced at Closing with respect to the Asset (or portion thereof) so excluded, subject to any adjustments as a result of any Title Defect asserted by Buyer in accordance with Section 10.1 and (y) Sellers shall assign to Buyer the Asset (or portion thereof) so excluded at Closing pursuant to an instrument in substantially the same form as the Assignment. If such Consent has not been obtained as of the Final Settlement Date, then, unless Buyer waives the Consent requirement, the affected Asset shall be deemed an Excluded Asset and Sellers shall retain such Asset.

(ii) If Sellers fail to obtain a Consent set forth in Schedule 4.4 prior to Closing that is not a Required Consent, then the Asset (or portion thereof) subject to such un-obtained Consent shall nevertheless be assigned by Sellers to Buyer at Closing as part of the Assets.

(c) With respect to any Asset that requires notification of assignment, Sellers shall, no later than five (5) days after the Closing Date, send to the applicable counterparty a written notice in compliance with the contractual provisions thereof.

10.6 Additional Interests. (a) From the Execution Date until the last day of the Cure Period, notwithstanding Section 6.1 but subject to Section 10.6(d), a Seller (or its Affiliates) may acquire (solely for the purposes of conveying to Buyer) additional oil, gas and/or mineral leases that are Approved Leases (each such acquired interest and each other oil and gas lease such Seller (or its Affiliates) owns within the Designated Area as of the Execution Date but not described in Exhibit A-1 on the Execution Date, in each case meeting the parameters of this Section 10.6(a), such Seller’s “Additional Interests”).

(b) If Buyer exercises its right to extend the Target Closing Date under Section 8.1, subject to the remainder of this Section 10.6(b), all Additional Interests a Seller (or its Affiliates) obtains title of record and notifies Buyer in writing, in each case, prior to November 15, 2017 (the “Additional Interests Cutoff Date”) shall be conveyed to Buyer at Closing and, subject to the cap set forth in Section 10.6(d), the Purchase Price shall be increased by the aggregate Additional Interest Values attributable to such conveyed Additional Interests (subject to, without duplication. all other adjustments to the Purchase Price under this Agreement). Notwithstanding anything to the contrary, the conveyance of any Additional Interest at Closing shall be subject to (i) Buyer’s confirmation that the applicable Additional Interests are Approved Leases and that all payments required to acquire such Additional Interests were paid by such Seller (or its Affiliates), (ii) the cap set forth in Section 10.6(d), and (iii) Buyer’s right to, on or before 5:00 p.m. (Central Time) time on the twentieth (20th) day after (1) the Additional Interests Cutoff Date or (2) such later date on which all required title documentation is provided to Buyer, (A) conduct title review and environmental due diligence on all Additional Interests to be conveyed, and (B) assert any matter Buyer deems to constitute a Title Defect pursuant to procedures set forth in Section 10.1 (which shall apply mutatis mutandis, except for Section 10.1(e)) or an Environmental Defect pursuant to procedures set forth in Section 10.3 (which shall apply mutatis mutandis, except for Section 10.3(c)). Such Seller shall be entitled to cure each Title Defect asserted under this Section 10.6(b) in accordance with Section 10.1(b) and each Environmental Defect asserted under this Section 10.6(b) in accordance with Section 10.3(a). All uncured Title Defects and all uncured Environmental Defects properly asserted under this Section 10.6(b) shall be taken into account (and adjustments made in respect thereof) to the fullest extent possible in accordance with Section 10.1 and Section 10.3 (including Buyer’s right under Section 10.3(b)), as applicable.

(c) Subject to the remainder of this Section 10.6(c), if Closing occurs, (x) if Buyer does not exercise its right to extend the Target Closing Date under Section 8.1, all Additional Interests a Seller (or its Affiliates) obtains title of record and notifies Buyer in writing, in each case, before the last day of the Cure Period, or (y) if Buyer exercises its right to extend the Target Closing Date under Section 8.1, all Additional Interests a Seller (or its

Affiliates) obtains title of record and notifies Buyer in writing, in each case, between the Additional Interests Cutoff Date and the last day of the Cure Period, shall be conveyed to Buyer and, subject to the cap set forth in Section 10.6(d), the Purchase Price shall be increased by the aggregate Additional Interest Values attributable to such conveyed Additional Interests (subject to, without duplication. all other adjustments to the Purchase Price under this Agreement). Notwithstanding anything to the contrary, the conveyance of any Additional Interest under this Section 10.6(c) shall be subject to (i) Buyer’s confirmation that the applicable Additional Interests are Approved Leases and that all payments required to acquire such Additional Interests were paid by such Seller (or its Affiliates), (ii) the cap set forth in Section 10.6(d), and (iii) Buyer’s right to on or before 5:00 p.m. (Central Time) time on the thirtieth (30th) day after (1) the end of the Cure Period or (2) such later date on which all required title documentation is provided to Buyer (such period, the “Post-Closing Review Period”), (A) conduct title review and environmental due diligence on all Additional Interests to be conveyed, and (B) assert any matter Buyer deems to constitute a Title Defect pursuant to procedures set forth in Section 10.1 (which shall apply mutatis mutandis, except for Section 10.1(e)) or an Environmental Defect pursuant to procedures set forth in Section 10.3 (which shall apply mutatis mutandis, except for Section 10.3(c)).

All Additional Interests that have not been conveyed to Buyer within 60 days following the end of the Cure Period, shall be permanently excluded from the transaction contemplated hereunder.

ARTICLE XI

TERMINATION

11.1 Termination. This Agreement may be terminated at any time prior to Closing:

(a) by the mutual written consent of Sellers and Buyer;

(b) by either Buyer or Sellers if Closing has not occurred on or before December 31, 2017 or such later date as agreed to in writing by Buyer and Sellers (the “Outside Date”);

(c) by Buyer, upon delivery of written notice to Sellers at any time prior to the Closing in the event that a Seller has breached in any material respect any representation, warranty or covenant contained in this Agreement, Buyer has notified Sellers of the breach in writing, and the breach has continued without cure for a period of thirty (30) days after the written notice of breach;

(d) by Sellers, upon delivery of written notice to Buyer at any time prior to the Closing in the event that Buyer has breached in any material respect any representation, warranty or covenant contained in this Agreement, Sellers have notified Buyer of the breach in writing, and the breach has continued without cure for a period of thirty (30) days after the written notice of breach; and

(e) by Buyer if the condition set forth in Section 7.2(h) has not been satisfied as of the Target Closing Date; or

(f) by Buyer if the condition set forth in Section 7.2(i) has not been satisfied as of the Target Closing Date;

provided, however, that no Party shall be entitled to terminate this Agreement under this Section 11.1 if the Closing has failed to occur because such Party failed to perform or observe in any material respect its covenants or agreements hereunder;

11.2 Effect of Termination. If this Agreement is terminated pursuant to Section 11.1, this Agreement shall become void and of no further force or effect (except for the provisions of Sections 4.15, 5.7, 6.3, 9.1, 11.2, 11.3 and Article XIII which shall continue in full force and effect) and Sellers 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 party without any restriction under this Agreement; provided that a termination of this Agreement shall not relieve any breach by such Party of this Agreement occurring prior to such termination.

11.3 Remedies Upon Termination.

(a) Buyer’s Breach. If Closing does not occur because (i) Buyer fails to tender performance at Closing when (A) all of the conditions in Sections 7.2(a)-(h) and (j) that, by their terms, can be satisfied prior to Closing have been satisfied (or waived by Buyer) (unless the failure to satisfy such condition arises from the action or inaction by Buyer) and (B) Sellers are ready, willing and able to consummate the transactions hereunder, or (ii) Buyer terminates

this Agreement pursuant to Section 11.1(f), then Sellers may, as their sole and exclusive remedy, terminate this Agreement pursuant to Section 11.1 (to the extent not already terminated) and retain the Deposit as liquidated damages, free of any claims by Buyer or any other Person with respect thereto. The right to retain the Deposit as described in the preceding sentence shall be Sellers’ sole and exclusive remedy and in full and complete satisfaction of any losses that may be suffered by Sellers as a result of such termination and Sellers shall be deemed to have waived any and all other rights and remedies available to Sellers in respect of such termination (including liability for breach of this Agreement before such termination). IT IS EXPRESSLY STIPULATED BY THE PARTIES THAT THE ACTUAL AMOUNT OF DAMAGES RESULTING FROM SUCH TERMINATION WOULD BE DIFFICULT IF NOT IMPOSSIBLE TO DETERMINE ACCURATELY BECAUSE OF THE UNIQUE NATURE OF THIS AGREEMENT, THE UNIQUE NATURE OF THE OIL AND GAS INTERESTS, THE UNCERTAINTIES OF APPLICABLE COMMODITY MARKETS AND DIFFERENCES OF OPINION WITH RESPECT TO SUCH MATTERS, AND THAT THE LIQUIDATED DAMAGES PROVIDED FOR HEREIN ARE A REASONABLE ESTIMATE BY THE PARTIES OF SUCH DAMAGES UNDER THE CIRCUMSTANCES AND DO NOT CONSTITUTE A PENALTY.

(b) Seller’s Breach. If Closing does not occur because any Seller fails to tender performance at Closing when (A) all of the conditions in Section 7.1 that, by their terms, can be satisfied prior to Closing have been satisfied (or waived by Sellers) (unless the failure to satisfy such condition arises from the action or inaction by any Seller) and (B) Buyer is ready, willing and able to consummate the transactions hereunder, (i) (AA) Sellers shall promptly return by wire transfer of immediately available funds the Extension Payment and (BB) Sellers shall promptly return by wire transfer of immediately available funds, the Deposit to Buyer, free of any claims by Sellers or any other Person with respect thereto, and (ii) Buyer, at its sole option, shall be entitled to (x) pursue all legal and equitable remedies it has (including specific performance), or (y) terminate this Agreement pursuant to Section 11.1(c) and seek damages from Sellers; provided, however, that if Buyer elects to enforce specific performance of this Agreement, Buyer must pursue such remedy in lieu of all other legal and equitable remedies. In the event the Deposit is returned to Buyer and Buyer elects to enforce specific performance of this Agreement, after such return of the Deposit to Buyer, the Deposit shall be deemed to be zero for all purposes of this Agreement.

(c) Termination Pursuant to Section 11.1. If any Party terminates this Agreement pursuant to Section 11.1 for reasons other than those described in Section 11.3(a) or Section 11.3(b), then neither Sellers nor Buyer shall have any liability to the other Parties for termination of this Agreement, except that Sellers shall promptly return by wire transfer of immediately available funds, the Deposit to Buyer. If Buyer or Sellers terminates this Agreement pursuant to Section 11.1 and asserts that a breach of this Agreement has occurred, the notice of termination shall include a statement describing the nature of the alleged breach, together with supporting documentation.

In no event shall Sellers be required to indemnify the Buyer Indemnified Parties for Liabilities under Section 12.2(a) (excluding any breach by Sellers of any Seller Designated Representation) exceeding, in the aggregate, twenty percent (20%) of the unadjusted Purchase Price.

(b) Notwithstanding anything herein or in any Transaction Document to the contrary, the obligations and rights of the Parties hereunder, and the Liabilities for which any Indemnified Party is obligated to indemnify or entitled to indemnity under Section 12.2(a) or Section 12.3(a) shall be determined and calculated by excluding and without giving effect to any qualifiers as to materiality or material adverse effect set forth in any representation or warranty.

(a) Upon Closing, Buyer shall deliver to the Escrow Agent an amount equal to Three Million Dollars ($3,000,000.00) pursuant to Section 8.3(d) to be held in the Escrow Account (such amount, the “Indemnity Escrow Amount”). Without limiting Sellers’ indemnity obligations under Section 12.2, the Indemnity Escrow Amount will provide a non-exclusive source of funds to satisfy any Liabilities incurred or sustained by Buyer or its Affiliates arising from any Third Party Claims that Sellers have obligations to indemnify under Section 12.2. To the extent that Buyer desires to apply any portion of the Indemnity Escrow Amount to satisfy any such Liabilities, Buyer shall promptly notify Sellers of the same and within three Business Days of its receipt of Buyer’s notice, Sellers will notify Buyer of their election to either (i) satisfy such Liabilities out of the Escrow Account, in which case the Parties shall provide joint written instructions to the Escrow Agent to remit an amount necessary to satisfy such Liabilities from the Escrow Account to the Person(s) claiming the same or (ii) pay to a court of competent jurisdiction an amount equal to the amount of such Liabilities, in which case the Parties shall provide joint written instructions to the Escrow Agent to remit such amount to such court from the Escrow Account and Sellers shall thereafter be responsible for prosecuting any and all claims relating thereto at their sole cost and expense.

(b) On the date that is ninety (90) days following the Closing Date, the Parties shall instruct the Escrow Agent to release to Sellers the positive difference between the existing amount of the Indemnity Escrow Amount and the sum of (i) the aggregate amount of all unsatisfied claims for indemnification that Buyer has made on or before such date pursuant to this Article XII and which are to be satisfied (in whole or in part) from the Indemnity Escrow Amount and (ii) 50% of the Indemnity Escrow Amount. Notwithstanding the foregoing, on the date that is one hundred eighty (180) days following the Closing Date, the Parties shall instruct the Escrow Agent to release to Sellers the balance of the Indemnity Escrow Amount remaining in the Escrow Account less the aggregate amount of all unsatisfied claims for indemnification that Buyer has made on or before such date pursuant to this Article XII to Sellers. Notwithstanding anything herein to the contrary, the Defect Escrow Amount shall remain in escrow until released pursuant to Section 3.5(a) or Section 3.6, as applicable.

12.6 Express Negligence. THE DEFENSE, INDEMNIFICATION, HOLD HARMLESS AND RELEASE PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE LIABILITIES, LOSSES, COSTS, EXPENSES AND DAMAGES IN QUESTION AROSE OR RESULTED SOLELY OR IN PART FROM THE GROSS, SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY INDEMNIFIED PARTY. BUYER AND SELLERS ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

12.7 Exclusive Remedy. Notwithstanding anything to the contrary contained in this Agreement, the Parties agree that, from and after Closing, Section 3.5, Section 3.7, Section 10.1(b), Section 10.2, Section 10.4, Section 12.2, Section 12.3 and Section 13.1, and the special warranties set forth in the Assignment, contain the Parties’ exclusive remedies against each other with respect to the transactions contemplated hereby, including breaches of the representations, warranties, covenants and agreements of the Parties contained in this Agreement; provided, however, that, nothing herein shall be deemed a waiver of either Party’s right to seek injunctive relief or to compel specific performance of any covenant or obligation of the other Party.

12.8 Indemnification Procedures. All claims for indemnification under Section 12.2 and Section 12.3 shall be asserted and resolved as follows:

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

(b) To make claim for indemnification under Section 12.2 or Section 12.3, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 12.8, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Third Party Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided, however, that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 12.8(b) shall not relieve the Indemnifying Party of its obligations under Section 12.2 or Section 12.3 (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. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Third Party Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

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

(d) If the Indemnifying Party admits its liability to defend the Indemnified Party against a Third Party Claim, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Indemnified Party against such Third Party Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 12.8(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Party does not admit its liability or admits its liability to defend the Indemnified Party against a Third Party Claim, but fails to diligently prosecute, indemnify against or settle the Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability and assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its

liability to defend the Indemnified Party against a Third Party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its liability to indemnify the Indemnified Party from and against the liability and either consent to or reject such proposed settlement, in its reasonable judgment, or (ii) deny liability. Any failure to respond such notice by the Indemnified Party shall be deemed to be an election under subsection (ii) above.

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

(g) Without limiting in any manner the provisions of Section 12.2, the indemnity, savings and hold harmless obligations of Sellers pursuant to Section 12.2 and the term “Liabilities” as used in Section 12.2 are intended to and do cover Liabilities incurred by any Buyer Indemnified Party which (1) arise from the breach of this Agreement or any Transaction Document by Sellers or any Seller Indemnified Party and (2) do not involve any Third Party Claim.

12.9 Survival.

(a) Sellers’ indemnification obligation under Section 12.2(a) shall only apply if Buyer has provided Sellers with written notice claiming indemnification within nine (9) months of the Closing, except for (i) any breach of Sections 4.1, 4.2, 4.5, 4.6, 4.15 or 4.29 which shall survive Closing indefinitely, (ii) any breach of Section 4.13, which shall survive until eighteen (18) months following the Closing, and (iii) any breach of Section 4.14, which shall survive the Closing until the expiration of the applicable statute of limitations.

The remainder of this Agreement shall survive the Closing indefinitely except as may otherwise be expressly provided herein. Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

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

(a) Except as otherwise specifically provided, all fees, costs and expenses incurred by Buyer or Sellers in negotiating this Agreement or in consummating the transactions contemplated by this Agreement shall be paid by the Party incurring the same, including, legal and accounting fees, costs and expenses. All required documentary, filing and recording fees and expenses in connection with the filing and recording of the assignments, conveyances or other instruments required to convey title to the Assets to Buyer shall be borne by Buyer.

(b) To the extent that any sales, use, transfer or similar Taxes (“Transfer Taxes”) are imposed on the purchase and sale of the Assets pursuant to this Agreement, Buyer, on the one hand, and Sellers, on the other hand, shall each bear and pay fifty percent (50%) of such Transfer Taxes. Sellers and Buyer shall reasonably cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Transfer Taxes.

(c) Sellers shall be allocated and bear all Asset Taxes attributable to (A) any Tax period ending prior to the Effective Time and (B) the portion of any Straddle Period ending immediately prior to the Effective Time, and, subject to the occurrence of the Closing, Buyer shall be allocated and bear all Asset Taxes attributable to (X) any Tax period beginning at or after the Effective Time and (Y) the portion of any Straddle Period beginning at the Effective Time.

For purposes of clause (iii) of the preceding sentence, the period for such Asset Taxes shall begin on the date on which ownership of the applicable assets gives rise to liability for the particular Asset Tax and shall end on the day before the next such date.

(e) To the extent the actual amount of an Asset Tax is not known at the time an adjustment to the Purchase Price is to be made with respect to such Asset Tax pursuant to Section 3.3, 3.4 or 3.5, as applicable, the Parties shall utilize the most recent information available in estimating the amount of such Asset Tax for purposes of such adjustment. To the extent the actual amount of an Asset Tax (or the amount thereof paid or economically borne by a Party) is ultimately determined to be different than the amount (if any) that was taken into account in the Final Settlement Statement as finally determined pursuant to Section 3.5, timely payments will be made from one Party to the other to the extent necessary to cause each Party to bear the amount of such Tax that is allocable to such Party under Section 13.1(c) and Section 13.1(d).

No Party shall assign all or any part of this Agreement, nor shall any Party assign or delegate any of its rights or duties hereunder, without the prior written consent of the other Parties, such consent to be withheld for any reason, and any assignment or delegation made without such consent shall be void. Notwithstanding the preceding, Buyer may assign this Agreement prior to Closing to any Affiliate without the prior written consent of Sellers; provided that such assignment shall not relieve Buyer of any of its obligations and responsibilities hereunder. Further and notwithstanding the preceding, Buyer is aware that Sellers intend to perform an IRC Section 1031 tax-deferred exchange, and to that extent, Sellers may assign interests of Leases contemplated hereunder to each other in order to accomplish such tax-deferred exchanges; provided such assignments shall contain customary special warranties of title by the assignor and Sellers shall promptly and in any event no later than three (3) Business Days prior to the Defect Claim Date, provide written notice to Buyer of any such assignment together with executed copies of the applicable assignment and ▇▇▇▇ of sale. Sellers shall further have the right at any time prior to Closing to assign all or a portion of their rights under this Agreement (the “Assigned Rights”) to designated qualified intermediary (as defined in Treasury Regulation Section 1.1031(k)(1)(g)(4)(iii)) 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 (an “Exchange”). In the event Sellers assign the Assigned Rights to a qualified intermediary pursuant to this Section 13.2, then Sellers agree to notify Buyer in writing of such assignment at or before Closing. Buyer hereby consents to any such assignment and Buyer agrees to pay the Purchase Price (as may be adjusted under the terms of this Agreement) for the Assets into a qualified escrow or qualified trust account at Closing as directed by the qualified intermediary and Sellers in writing; provided that (a) the Closing shall not be delayed or affected by any reason of the Exchange, (b) Sellers shall effect the Exchange through an assignment of the Assigned Rights to a qualified intermediary, but such assignment shall not relieve Sellers from, or modify, of any of their obligations and responsibilities hereunder (including indemnity obligations) to Buyer under this Agreement; and (c) Sellers shall indemnify Buyer against any additional costs or liabilities incurred by Buyer on account of Sellers’ consummation of the transaction through an Exchange. Buyer, by its consent to an Exchange, shall not be responsible in any way for Sellers’ compliance with such Exchange.

Subject to the foregoing, this Agreement shall be binding upon the Parties and their successors and permitted assigns.

13.3 Preparation of Agreement. Sellers and Buyer and their respective counsels participated in the preparation of this Agreement. In the event of any ambiguity in this Agreement, no presumption shall arise based on the identity of the draftsman of this Agreement.

13.4 Notices. All notices and communications required or permitted to be given hereunder shall be in writing and shall be delivered personally, or sent by bonded overnight courier, or mailed by U.S. Express Mail, or sent by facsimile (provided any such facsimile transmission is confirmed either orally or by written confirmation), or sent be electronic mail transmission (“email”) (provided that receipt of such email is requested and received, excluding automatic receipts) or addressed to the appropriate Party at the address for such Party shown below or at such other address as such Party shall have theretofore designated by written notice delivered to the Party giving such notice:
