After execution and delivery of this Agreement, each Seller will make available (during such Seller’s regular business hours and at its current location) for Buyer’s due diligence review, the Records in Seller Group’s and the Existing Partnerships’ possession or control relating to title to the Oil and Gas Properties and reasonable access to such Seller’s and the Existing Partnerships’ personnel. If Buyer requests copies of such Records, Sellers will, and will cause the Existing Partnerships to, use Commercially Reasonable Efforts to promptly provide the requested copies to Buyer at Buyer’s expense.

4.2 Title Defect Notice. Buyer will provide Sellers with written notice (a “Title Defect Notice”) at or before 5:00 p.m. (central standard time) on June 13, 2017 (“Defect Notification Deadline”) of any matter that Buyer intends to assert as a Title Defect under this Article 4; provided, however, that Buyer will provide Sellers with a preliminary Title Defect Notice each Friday at or before 5:00 p.m. (central standard time) until the Defect Notification Deadline if any officer of Buyer or its Affiliates discovers or learns of any Title Defect during each such one-week period; provided, further, that no delay on the part of the Buyer in notifying the Sellers on a weekly basis prior to the Defect Notification Deadline will relieve the Sellers of any liability or obligation hereunder or adversely affect any of Buyer’s rights hereunder. The Title Defect Notice must include, in reasonable detail, to the extent then reasonably known by Buyer and to the extent applicable, a description of (i) the Oil and Gas Property with respect to which the claimed Title Defect relates (the “Title Defect Property”), (ii) the nature of such claimed Title Defect, (iii) Buyer’s proposed calculation of each Title Defect Value in accordance with the guidelines set forth in Section 4.6, and (iv) such supporting documents reasonably necessary for Sellers to verify the existence of such alleged Title Defect. Any Title Defect that is not identified in a delivered Title Defect Notice prior to the Defect Notification Deadline is thereafter forever waived by Buyer and such Title Defect will become a Permitted Encumbrance; provided, however, that the foregoing shall not modify or limit the special warranty of title included in the Conveyance or in the Reorganization Wells Warranty (as hereinafter defined) and no Title Defect arising from events and circumstance first occurring (and not due to the acts or omissions of Buyer) during the period from and after the Defect Notification Deadline and prior to the Closing Date will become a Permitted Encumbrance or Assumed Liability (and the same shall be a Sellers’ Retained Liability) unless Buyer agrees in writing to include the same as a Permitted Encumbrance and/or Assumed Liability. To the extent any such Title Defect arises pursuant to the foregoing and is a Retained Liability, Buyer shall grant Sellers reasonable access, from and after the Closing Date, and shall reasonably cooperate with Sellers, including providing documentation as reasonably requested by Sellers, in each case, with respect to any cure efforts of Sellers related to such Sellers’ Retained Liability. To give Buyer the benefit of Sellers’ special warranty of title for the Reorganization Wells, at Closing Sellers shall warrant and defend title to the Reorganization Wells unto Buyer, its successors and assigns, against all claims by, through or under Sellers and any Existing Partnership, but not otherwise, by execution of a warranty in the form attached Exhibit F attached hereto and incorporated herein by reference (the “Reorganization Wells Warranty”).

4.3 Sellers’ Right to Cure Title Defects. Subject to the provisions of this Section 4.3, Sellers have the right, but not the obligation, to cure prior to Closing any Title

Defect at Sellers’ sole cost. If Sellers elect to cure a Title Defect and such cure has not been completed to the reasonable satisfaction of Buyer on or before three (3) days prior to the Closing Date, then Sellers shall make an election pursuant to Section 4.4; provided, however, that Sellers shall have a continuing right to cure after Closing under Section 4.4.2.

4.4 Remedies for Title Defects. Subject to Sellers’ continuing right to dispute the existence of a Title Defect or the Title Defect Value asserted with respect thereto, in the event that any Title Defect is timely asserted by Buyer in accordance with Section 4.2 and is not waived in writing by Buyer or cured prior to Closing pursuant to Section 4.3, then Sellers shall elect one of the following options:

4.4.1 At Closing, Sellers may assign the Title Defect Property to Buyer and the Title Defect Value for such Title Defect Property determined pursuant to Sections 4.6 and Section 4.7 shall be taken into account in the calculation of the Uncured/Unremedied Adjustment Amount; provided, however, that if the Title Defect Value or the existence of the Title Defect is still in dispute at Closing, then (i) the Title Defect Value for such Title Defect Property calculated by Buyer in the Title Defect Notice shall be taken into account in the calculation of the Uncured/Unremedied Adjustment Amount and (ii) within three (3) Business Days after such dispute is resolved pursuant to Section 4.7, either Buyer shall make a true-up payment to Sellers or Sellers shall reimburse Buyer, for an amount equal to the difference, if any, between the Uncured/Unremedied Adjustment Amount applied at Closing and the Uncured/Unremedied Adjustment Amount determined after Closing in accordance with Section 4.7.

4.4.2 At Closing, Sellers may retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all Properties primarily related thereto, and the Purchase Price shall be reduced by an amount equal to the sum of the Allocated Values for such Title Defect Property and related Properties pursuant to Section 3.3.4, and such Title Defect Property and related Properties shall be deemed Excluded Assets. Thereafter, Sellers shall have 180 days in which to cure such Title Defect (the “Cure Period”). If such Title Defect is cured prior to expiration of the Cure Period, then such retained Properties shall be conveyed to Buyer in accordance with Section 4.9. In the event that Sellers are unable to cure such Title Defect prior to expiration of the Cure Period, then Sellers shall retain such Properties, such Properties shall be permanently deemed to be Excluded Assets and Buyer shall have no further obligation to purchase such retained Properties.

4.4.3 With the consent of Buyer (in Buyer’s sole discretion), at Closing, Sellers may assign the Title Defect Property to Buyer without an adjustment to the Purchase Price under Section 3.3.6 and shall indemnify Buyer against all Liabilities resulting from such Title Defect with respect to the affected Oil and Gas Properties pursuant to a mutually agreed indemnity agreement between the Parties (a “Title Indemnity Agreement”).

4.5 Exclusive Remedy. Except for Buyer’s rights under Sellers’ special warranty of title in the Conveyance and the Reorganization Wells Warranty, Buyer’s right to terminate this Agreement pursuant to Section 15.1.6, and Buyer’s rights under any Title Indemnity Agreement,

the provisions set forth in Section 4.3 and Section 4.4 shall be the exclusive right and remedy of Buyer with respect to Sellers’ (or with respect to the Reorganization Wells, the Drilling Partnerships’) failure to have Good and Defensible Title with respect to any of the Properties and any other title matters. Buyer acknowledges and agrees that it shall not have the right to make any Claim pursuant to this Agreement to the extent it has recovered amounts relating to such Claim pursuant to Sellers’ special warranty of title in the Conveyance or the Reorganization Wells Warranty.

4.6 Calculation of Title Defect Value. The amount of the Title Defect Value for a Title Defect Property shall be determined as follows:

4.6.1 If, because of the Title Defect, title to a particular Oil and Gas Property fails completely with the effect that the applicable Seller (or with respect to the Reorganization Wells, the applicable Drilling Partnership) has no ownership interest in the relevant Oil and Gas Property, the Title Defect Value will be the Allocated Value of that Oil and Gas Property and, unless such Oil and Gas Property is a Reorganization Well, such Oil and Gas Property shall be an Excluded Asset.

4.6.2 If a Title Defect operates as a Net Reduction of Interest in an Oil and Gas Property and such Oil and Gas Property has an Allocated Value assigned specifically to it on Exhibit B, then the Title Defect Value will be the Allocated Value for such Oil and Gas Property multiplied by a fraction (i) the numerator of which is the net present value, as of the Effective Time, of the applicable Seller’s (or with respect to the Reorganization Wells, the applicable Drilling Partnership’s) ownership interest in such Oil and Gas Property as shown on Exhibit A-2 (the “PV-NRI”) minus the net present value as of the Effective Time, of the applicable Seller’s (or with respect to the Reorganization Wells, the applicable Drilling Partnership’s) actual ownership interest in such Oil and Gas Property calculated based upon the same production, cost, and assumed future price estimates and discount rate and such other methods, techniques and assumptions utilized in determining PV-NRI but taking into account the Title Defect, and (ii) the denominator of which is the PV-NRI.

4.6.3 If a Title Defect results from the applicable Seller (or with respect to the Reorganization Wells, the applicable Drilling Partnership) owning fewer net acres in a category on Exhibit A-1 and such category has an Allocated Value assigned specifically to it on Exhibit B, then the Title Defect Value will be the Allocated Value of such category multiplied by a fraction (i) the numerator of which is the difference between (a) the net acres of the Oil and Gas Property in such category set forth on Exhibit A-1, minus (b) the net acres of the Oil and Gas Property in such category as of the Closing Date and (ii) the denominator of which is the net acres of the Oil and Gas Property in such category set forth on Exhibit A-1.

4.6.4 If a Title Defect is an Encumbrance upon an Oil and Gas Property which is liquidated in amount, then the Title Defect Value for such Title Defect shall be the amount necessary to be paid to remove the Title Defect from the affected Oil and Gas Property at Closing.

4.6.5 If a Title Defect represents an obligation or burden upon an Oil and Gas Property of a type not described in Sections 4.6.1 through 4.6.4, then the Title Defect Value with respect to such Title Defect will be the sum the Parties mutually agreed upon in good faith as the present value of the adverse economic effect such Title Defect will have on such Oil and Gas Property. If the Parties cannot reach an agreement as to such Title Defect Value, then the Parties will resolve such dispute in the manner set forth in Section 4.7.

4.6.6 With the exception of Encumbrances described in Section 4.6.4, notwithstanding anything else to the contrary under this Section 4.6 or Section 4.7, in no event will the aggregate Title Defect Values with respect to an Oil and Gas Property exceed the Allocated Value of such Oil and Gas Property, and if such Oil and Gas Property does not have an Allocated Value, the Allocated Value of such Oil and Gas Property shall be deemed to be $0.00.

4.7.1 Within five (5) Business Days after Sellers’ receipt of a Title Defect Notice, Sellers will notify Buyer as to whether Sellers agree with the Title Defects claimed therein and the proposed Title Defect Values. If Sellers object to any such claimed Title Defect or any such proposed Title Defect Values, then the Parties will promptly enter into good faith negotiations and subject to the limitations in Section 4.6.6, the value agreed by the Parties with respect to a Title Defect will be the Title Defect Value for such Title Defect.

4.7.2 If the Parties do not reach agreement concerning either the existence of a Title Defect or a Title Defect Value prior to Closing, then, upon either Party’s written request, the Parties will submit such dispute to an attorney or other consultant experienced in title examination of oil and gas properties in the state in which such Oil and Gas Property is located to arbitrate a prompt resolution (the “Title Arbitrator”). The Title Arbitrator shall be selected by (i) mutual agreement of Sellers and Buyer within five (5) Business Days after a Party’s written request to submit such dispute for resolution, or (ii) if the Parties cannot agree, by the Houston office of the American Arbitration Association; provided, however, that if at any time any Title Arbitrator fails or refuses to perform under this Section 4.7, the Parties will select a new Title Arbitrator in accordance with this sentence. The Parties will bear the cost of any Title Arbitrator 50% by Sellers (collectively) and 50% by Buyer.

4.7.3 For any dispute resolution process under this Section 4.7, Sellers and Buyer will present a written statement of their respective positions on the dispute to the Title Arbitrator within three (3) Business Days after the Title Arbitrator is selected, and the Title Arbitrator will make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within ten (10) Business Days of receipt of such statements. The Title Arbitrator’s determination will be conclusive and binding on the Parties. Any court of competent jurisdiction may enforce the arbitration determination against either Party and the Title Arbitrator’s value determination will be the Title Defect Value for such Title Defect.

4.7.4 Subject to Sellers’ right to cure pursuant to Section 4.3 and Section 4.4.2 and Sellers’ right to assign any Title Defect Property with a disputed Title Defect pursuant to Section 4.4.1, if any Title Defect Property is subject to a dispute under this Section 4.7 at the time of Closing: (i) such Title Defect Property, together with all Properties primarily related thereto (but not a Reorganization Well), shall be deemed to be Excluded Assets and shall be retained by Sellers at Closing, and (ii) the Purchase Price will be reduced by the sum of the Allocated Values for such retained Properties. After the Title Arbitrator or the Parties resolve the disputed issues pursuant to this Article 4 with respect to any Title Defect Property that is retained by Sellers pursuant to this Section 4.7.4, such retained Property shall be conveyed to Buyer in accordance with Section 4.9 (unless the subject Title Defect Value is equal to or greater than the Allocated Values of such retained Properties, in which event, Sellers may elect, in their sole discretion, to permanently retain such Properties, unless such Properties are Reorganization Wells).

4.8 Possible Upward Adjustment. Should Sellers (or Buyer in the course of its diligence review pursuant to Section 4.1) determine that (i) the ownership of an Oil and Gas Property by Sellers (or with respect to the Reorganization Wells, the Drilling Partnerships) entitles the applicable Seller (or with respect to the Reorganization Wells, the applicable Drilling Partnership) to a decimal share of the Hydrocarbons produced from such Oil and Gas Property greater than the applicable Net Revenue Interest set forth in Exhibit A-2, or that Sellers own more net acres in a category on Exhibit A-1 and such category has an Allocated Value assigned specifically to it on Exhibit B, (ii) that there is an increase in the applicable Seller’s (or with respect to the Reorganization Wells, the applicable Drilling Partnership’s) Working Interest in an Oil and Gas Property described in Exhibit A-1 through Exhibit A-4 and Schedule 1.1 greater than the Working Interest as set forth in Exhibit A-2 for such Oil and Gas Property at any time during the productive life or abandonment thereof, as long as there is a corresponding proportionate increase in such Seller’s (or with respect to the Reorganization Wells, such Drilling Partnership’s) Net Revenue Interest for such Oil and Gas Property relative to what is shown on Exhibit A-2 for such Oil and Gas Property, then such Party shall calculate (in the same manner as set forth in Section 4.6 with respect to Title Defects) the amount by which the Allocated Value of such Oil and Gas Property is increased (an “Upward Adjustment”) and if an Upwards Adjustment exceeds the Individual Deductible Amount for an individual Property, the aggregate Uncured Title Defect Value asserted by Buyer shall be reduced by such Upward Adjustment. For clarity, in no event will any Upward Adjustment entitle Sellers to an adjustment for any reason other than to offset any Uncured Title Defect Value under this Section 4.8.

4.9 Delayed Closing. If any Properties are required to be conveyed to Buyer pursuant to Sections 4.4.2 or 4.7.4 after cure of a Title Defect or determination of a disputed Title Defect Value, then (i) such Properties shall be deemed to no longer be Excluded Assets and shall be Properties for all purposes under this Agreement, (ii) such Properties shall be conveyed on the date that is ten (10) Business Days after such Title Defect is cured by Sellers or after the Title Defect Value is finally determined (as applicable), (iii) such Properties shall be conveyed pursuant to an assignment in the form of the Conveyance, subject to the terms and conditions of this Agreement (including the Effective Time) and (iv) simultaneously with such Conveyance, subject to the Aggregate Deductible Amount, Buyer shall pay to Sellers the Allocated Values as

adjusted by any Title Defect Value, for such Properties solely to the extent not duplicative of adjustments already made to the Purchase Price (unless the subject Title Defect Value is equal to or greater than the Allocated Values of such retained Properties, in which event, Sellers may elect in their sole discretion, to permanently retain such Properties). Any survival periods relating to a Conveyance at a delayed Closing, shall begin to run on the date of such delayed Closing.

5.1.1 Without limitation on the rights and obligations of the Parties set forth in Section 9.3, Sellers shall promptly provide notices with respect to the Transfer Requirements that are preferential rights to purchase (“Preference Right”), and for the purpose of any Preference Right, the value of the applicable Property will be its Allocated Value, and Sellers will use Commercially Reasonable Efforts to obtain a waiver of or exercise by the holder of such Preference Right.

5.1.2 If (i) the holder of a Preference Right does not elect to purchase the applicable Property or waives its right to do so, or (ii) the time in which the Preference Right may be exercised (as set forth in the conveyance or other agreement pursuant to which such Preference Right was granted) has expired, then such Property will be assigned to Buyer (or vested with the applicable Drilling Partnership) at the Closing in accordance with the terms and subject to the conditions of this Agreement.

5.1.3 If, prior to the Closing Date, a holder of a Preference Right notifies a Seller that it elects to exercise its Preference Right with respect to the applicable Property, then (i) such Property, together with all Properties primarily related thereto, will not be conveyed to Buyer at Closing and will be deemed an Excluded Asset (or if such Property is a Reorganization Well owned by a Public Partnership, Sellers shall take such steps as are necessary to transfer such Property out of the Public Partnership), and (ii) the Purchase Price will be reduced by the applicable Allocated Values pursuant to Section 3.3.7 for such retained or transferred Properties, provided, however, if the holder of such Preference Right fails to complete the purchase of said Property (or portion thereof) within 180 days after the Closing Date (and in any event, outside any deadlines for exercise and closing set forth in the applicable conveyance or other agreement pursuant to which the Preference Right was granted), then Sellers may elect, in their discretion and upon written notice to Buyer, to deliver such retained or transferred Properties at a delayed closing pursuant to the procedures in Section 5.3.

5.1.4 Sellers shall promptly notify Buyer in writing of the exercise of any Preference Right in respect of the Properties.

5.2.1 Without limitation on the rights and obligations of the Parties set forth in Section 9.3, Sellers shall promptly provide any required notifications with respect to the

Transfer Requirements (other than Preference Rights) in any Material Contracts and Leases, and Sellers will use Commercially Reasonable Efforts to obtain a consent by the holder thereof to the transactions contemplated hereby with respect to the applicable Property.

5.2.2 If, prior to the Closing, all Transfer Requirements with respect to any Property (i) are fully satisfied, have expired (by the terms of the conveyance or other agreement pursuant to which such Transfer Requirements arose) or are no longer applicable to the transactions contemplated hereby, or (ii) are Permitted Encumbrances (other than pursuant to clause (xvii)(f) of the definition thereof), then such Property will be assigned to Buyer (or vested in the applicable Drilling Partnership) at the Closing in accordance with the terms and subject to the conditions of this Agreement.

5.2.3 If, prior to the Closing Date, a holder of a Transfer Requirement notifies any Seller that it refuses to consent (or waive its right to do so) to the transactions contemplated hereby with respect to the applicable Property, then (i) such Property, together with all Properties primarily related thereto, will not be conveyed to Buyer at Closing and will be deemed an Excluded Asset (or if such Property is a Reorganization Well owned by a Public Partnership, Sellers shall take such steps as are necessary to transfer such Property out of the Public Partnership), and (ii) the Purchase Price will be reduced by the applicable Allocated Values pursuant to Section 3.3.7 for such retained or transferred Properties; provided, however, if the holder of such Transfer Requirement provides such consent or waiver to satisfy the Transfer Requirement (or if such Transfer Requirement is otherwise fully satisfied, expires by the terms of the conveyance or other agreement pursuant to which such Transfer Requirements arose, or is no longer applicable to the transactions contemplated hereby) within 180 days after the Closing Date, then Sellers may elect, in their reasonable discretion and upon written notice to Buyer, to deliver such retained Properties at a delayed closing pursuant to the Section 5.3.

5.3 Delayed Closing. If any Properties are required to be conveyed to Buyer pursuant to Section 5.1.3 or Section 5.2.3, then (i) such Properties shall be deemed to no longer be Excluded Assets and shall be Properties for all purposes under this Agreement, (ii) such Properties shall be conveyed on the date that is ten (10) Business Days after Buyer’s receipt of Sellers’ written notice pursuant to Section 5.1.3 or Section 5.2.3 (as applicable), (iii) such Properties shall be conveyed pursuant to an assignment in the form of the Conveyance, subject to the terms and conditions of this Agreement (including the Effective Time) and (iv) simultaneously with such Conveyance, subject to the Aggregate Deductible Amount, Buyer shall pay to Sellers the Allocated Values for such Properties as otherwise adjusted solely to the extent not duplicative of adjustments already made to the Purchase Price. Any survival periods relating to a Conveyance at a delayed Closing shall begin to run on the date of such delayed Closing.

6.1 Environmental Assessment. Buyer will have the opportunity to conduct, at its sole risk and expense, an environmental assessment of the Properties, including a Phase I

assessment as such term is defined by the ASTM E1527-13 All Appropriate Inquiry Standard. Each Seller will provide reasonable access for this purpose to Properties operated by such Seller. For any Property not operated by a Seller, Sellers will reasonably cooperate with Buyer in contacting the operators of any such non-operated Property directly to attempt to arrange for access for the purposes of environmental assessment. Buyer shall not conduct any test drilling or sampling activities without prior notice to and consent of Sellers (in Sellers’ sole discretion) and the operator of the affected Property. Buyer shall provide Sellers with a minimum of three (3) Business Days’ advance notice of its proposed environmental assessment activities prior to entering the Property to be assessed. If Buyer wishes to utilize any third party personnel or contractors to perform any activities on any Property, Buyer shall obtain Sellers’ prior consent (which shall not be unreasonably withheld or delayed) to the use of such third party personnel or contractors, and shall provide Sellers with evidence reasonably satisfactory to Sellers that all such Persons have appropriate training and are covered by appropriate insurance.

6.2 Notice of Environmental Condition. Buyer will provide Sellers with written notice (an “Environmental Condition Notice”) on or before the Defect Notification Deadline of any condition that Buyer intends to assert as an Environmental Condition under this Article 6; provided, however, Buyer agrees to use its good faith efforts to notify Sellers of an Environmental Condition as promptly as possible after Buyer has discovered and made the decision to assert the same; provided that the failure to provide such good faith notice in advance of the Defect Notification Deadline shall not affect Buyer’s rights hereunder. Each Environmental Condition Notice must include, in as much detail as is commercially reasonable, a description of (i) the Property with respect to which such Environmental Condition is claimed (the “Environmental Condition Property”), (ii) the nature of such claimed Environmental Condition (including the applicable Environmental Laws violated or implicated thereby), and (iii) Buyer’s proposed calculation of the Remediation Amount. Any Environmental Condition that is not identified in a timely delivered Environmental Condition Notice is thereafter forever waived and expressly assumed by Buyer; provided, however, that no Environmental Condition arising wholly from events and circumstances first occurring (and not due to the acts or omissions of Buyer) during the period from and after the Defect Notification Deadline and prior to the Closing Date will be an Assumed Liability (and the same shall be a Sellers’ Retained Liability) unless Buyer expressly notifies Sellers of the same in writing no later than 21 days after Closing. To the extent any such Environmental Condition arises pursuant to the foregoing and is a Sellers’ Retained Liability, Buyer shall grant Sellers reasonable access, from and after the Closing Date, and shall reasonably cooperate with Sellers, including providing documentation as reasonably requested by Sellers, in each case, with respect to any Remediation of Sellers related to such Retained Liability.

6.3 Sellers’ Right to Cure Environmental Conditions. Subject to the provisions of this Section 6.3, Sellers will have the right, but not the obligation, to conduct Remediation for any Environmental Condition prior to Closing at Sellers’ sole cost in accordance with applicable Environmental Laws. If Sellers elect to conduct Remediation and the Remediation has not been completed prior to the Closing Date, pursuant to the procedures of Sections 6.3.1 and 6.3.2, then Sellers shall make an election to the extent permitted pursuant to Section 6.4; provided, however, that the Sellers shall have a continuing right to conduct Remediation after Closing under Section 6.4.2.

6.3.1 Within ten (10) Business Days after Sellers’ receipt of an Environmental Condition Notice, Sellers shall notify Buyer in writing of its election to conduct Remediation under this Section 6.3 and said notification shall include the proposed plan and schedule for the Remediation.

6.3.2 Within three (3) Business Days after Sellers’ completion of Remediation of any Environmental Condition, Sellers shall notify Buyer that the Remediation is complete. Within (5) Business Days after receipt by Buyer of Sellers’ notification that Remediation is complete, Buyer shall have (5) Business Days to inspect the Environmental Condition Property where Remediation was conducted and to notify Sellers in writing that Buyer concurs that Remediation is complete (which notice shall not be unreasonably withheld, conditioned or delayed).

6.4 Remedies for Environmental Conditions. Subject to Sellers’ right to dispute the existence of an Environmental Condition or the Remediation Amount asserted with respect thereto pursuant to Section 6.6, in the event that any Environmental Condition is timely asserted by Buyer in accordance with Section 6.2 and is not waived in writing by Buyer or subject to Remediation completed prior to the Closing, then Sellers shall, with written notice to Buyer, elect one of the following:

6.4.1 Sellers may assign the Environmental Condition Property to Buyer (or vest title thereto in the applicable Drilling Partnership) at Closing and the Remediation Amount for such Environmental Condition Property shall be taken into account in the calculation of the Uncured/Unremedied Adjustment Amount; provided, however, that if the Remediation Amount or the existence of an Environmental Condition is still in dispute at Closing, then (i) the Remediation Amount for such Environmental Condition Property calculated by Buyer in the Environmental Condition Notice shall be taken into account in the calculation of the Uncured/Unremedied Adjustment Amount and (ii) within three (3) Business Days after such dispute is resolved pursuant to Section 6.6, either Buyer shall make a true-up payment to Sellers or Sellers shall reimburse Buyer, for an amount equal to the difference, if any, between the Uncured/Unremedied Adjustment Amount applied at Closing and the Uncured/Unremedied Adjustment Amount determined after Closing in accordance with Section 6.6.

6.4.2 At Closing, Sellers may retain the entirety of the Environmental Condition Property (or if the Environmental Condition Property is owned by a Public Partnership, Sellers shall take such steps as are necessary to transfer such Environmental Condition Property out of the Public Partnership) that is subject to such Environmental Condition, together with all Properties primarily related thereto, and the Purchase Price shall be reduced by an amount equal to the sum of the Allocated Values for such Environmental Condition Property and related Properties pursuant to Section 3.3.5, and such Environmental Condition Property and related Properties shall be deemed Excluded Assets. If the Remediation is completed prior to expiration of the Cure Period in accordance with Section 6.3, then such retained Properties shall be conveyed to Buyer or the applicable Drilling Partnership in accordance with Section 6.7. In the event that Sellers are unable to complete Remediation prior to expiration of the Cure Period, then Sellers shall retain such Properties, such Properties shall be permanently deemed to be Excluded Assets, and Buyer shall have no further obligation to purchase such retained Properties.

6.4.3 With the consent of Buyer (in Buyer’s sole discretion) Sellers may assign the Environmental Condition Property to Buyer (or vest title thereto in the applicable Drilling Partnership) at Closing without an adjustment to the Purchase Price and shall indemnify Buyer against all Liabilities resulting from such Environmental Condition with respect to such Environmental Condition Property pursuant to a mutually agreed indemnity agreement between the Parties (an “Environmental Indemnity Agreement”).

6.5 Exclusive Remedy. Except for Buyer’s right to terminate this Agreement pursuant to Section 15.1.6, Sellers’ indemnification obligations for a breach of Sellers’ representation contained in Section 7.7, and Buyer’s rights under any Environmental Indemnity Agreement, the provisions set forth in Section 6.4 shall be the exclusive right and remedy of Buyer with respect to any environmental matter, including Environmental Conditions.

6.6.1 Within five (5) Business Days after Sellers’ receipt of an Environmental Condition Notice, Sellers will notify Buyer as to whether Sellers agree with the Environmental Conditions claimed therein and the proposed Remediation Amounts. If Sellers object to any such claimed Environmental Condition or any such proposed Remediation Amount, then the Parties will promptly enter into good faith negotiations and the amount agreed by the Parties with respect to an Environmental Condition will be the Remediation Amount for such Environmental Condition.

6.6.2 If the Parties do not reach agreement concerning either the existence of an Environmental Condition or a Remediation Amount prior to Closing, then, upon either Party’s written request, the Parties will submit such dispute to an environmental consultant or other consultant experienced in oil and gas producing property environmental remediation in the state in which such Property is located to arbitrate a prompt resolution (the “Environmental Arbitrator”). Such Environmental Arbitrator shall be selected by (i) mutual agreement of Sellers and Buyer within five (5) Business Days after the Party’s written request to submit such dispute for resolution, or (ii) if the Parties cannot agree, by the Houston office of the American Arbitration Association; provided, however, that if at any time any Environmental Arbitrator fails or refuses to perform under this Section 6.6, a new Environmental Arbitrator will be selected by the Parties in accordance with this sentence. The cost of any such Environmental Arbitrator will be borne 50% by Sellers (collectively) and 50% by Buyer.

6.6.3 For any dispute resolution under this Section 6.6, Sellers and Buyer will present a written statement of their respective positions on the dispute to the Environmental Arbitrator within three (3) Business Days after the Environmental Arbitrator is selected, and the Environmental Arbitrator will make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within ten (10) Business Days of receipt of such statements. The Environmental

Arbitrator’s determination will be conclusive and binding on the Parties and will be enforceable against either Party in any court of competent jurisdiction, and the Environmental Arbitrator’s value determination will be the Remediation Amount for such Environmental Condition.

6.6.4 Subject to Sellers’ right to cure pursuant to Section 6.3 and Section 6.4.2, and Sellers’ right to assign any Environmental Condition Property with a disputed Environmental Condition pursuant to Section 6.4.1, if any Environmental Condition Property is subject to a dispute under this Section 6.6 at the time of Closing: (i) such Environmental Condition Property, together with all Properties primarily related thereto, shall be deemed to be Excluded Assets and shall not be transferred to Buyer or vested in the new Drilling Partnership (or if the Environmental Condition Property is owned by a Public Partnership, Sellers shall take such steps as are necessary to transfer such Environmental Condition Property out of the Public Partnership) at Closing , and (ii) the Purchase Price will be reduced by the sum of the Allocated Values for such retained or transferred Properties. After the Environmental Arbitrator or the Parties resolve the disputed issues pursuant to this Section 6.6 with respect to any Environmental Condition Property that is not transferred to Buyer or a Drilling Partnership, as applicable, at Closing pursuant to this Section 6.6.4, such retained Properties shall be conveyed to Buyer or a Drilling Partnership, as applicable, in accordance with Section 6.7 (unless the subject Remediation Amount is equal to or greater than the Allocated Values of such retained Properties, in which event, Sellers may elect, in their sole discretion, or Buyer may require Sellers, to permanently retain such Properties).

6.7 Delayed Closing. If any Properties are required to be conveyed to Buyer pursuant to Section 6.4.2 or Section 6.6.4, then (i) such Properties shall be deemed to no longer be Excluded Assets and shall be Properties for all purposes under this Agreement, (ii) such Properties shall be conveyed on the date that is ten (10) Business Days after the Remediation is completed by Sellers or after the Remediation Amount is finally determined (as applicable), (iii) such Properties shall be conveyed pursuant to an assignment in the form of the Conveyance, subject to the terms and conditions of this Agreement (including the Effective Time) and (iv) simultaneously with such Conveyance, subject to the Aggregate Deductible Amount, Buyer shall pay to Sellers the Allocated Values as adjusted by any Remediation Amount, for such Properties solely to the extent not duplicative of adjustments already made to the Purchase Price (unless the subject Remediation Amount is equal to or greater than the Allocated Values of such retained Properties, in which event, Sellers may elect in their sole discretion, or Buyer may require Seller, to permanently retain such Properties). Any survival periods relating to a Conveyance at a delayed Closing shall begin to run on the date of such delayed Closing.

6.8 Presence of Wastes, NORM, Hazardous Substances and Asbestos. BUYER ACKNOWLEDGES THAT THE PROPERTIES HAVE BEEN USED TO EXPLORE FOR, DEVELOP AND PRODUCE HYDROCARBONS, AND THAT SPILLS OF WASTES, CRUDE OIL, PRODUCED WATER, HAZARDOUS SUBSTANCES AND OTHER MATERIALS MAY HAVE OCCURRED THEREON. ADDITIONALLY, THE PROPERTIES, INCLUDING PRODUCTION EQUIPMENT, MAY CONTAIN ASBESTOS, HAZARDOUS SUBSTANCES OR NORM. NORM MAY AFFIX OR ATTACH ITSELF TO THE INSIDE OF WELLS, MATERIALS AND EQUIPMENT AS SCALE OR IN OTHER FORMS, AND

NORM-CONTAINING MATERIAL MAY HAVE BEEN BURIED OR OTHERWISE DISPOSED OF ON THE PROPERTIES. A HEALTH HAZARD MAY EXIST IN CONNECTION WITH THE PROPERTIES BY REASON THEREOF. SPECIAL PROCEDURES MAY BE REQUIRED FOR REMEDIATION, REMOVING, TRANSPORTING AND DISPOSING OF ASBESTOS, NORM, HAZARDOUS SUBSTANCES AND OTHER MATERIALS FROM THE PROPERTY. With respect to the Properties actually acquired by Buyer hereunder or owned by a Drilling Partnership after the Reorganization, Buyer assumes from and after Closing all liability for the assessment, remediation, removal, transportation and disposal of these materials and any associated activities in accordance with applicable Laws, unless otherwise provided in this Article 6. The foregoing shall not modify or limit Sellers’ indemnity and hold harmless obligations under Section 18.1.

7.25 Lease Status. Neither Sellers nor the Drilling Partnerships have received a written notice from any Person of (a) an outstanding breach or termination of any Lease or (b) alleging that a Lease is invalid.

(i) There are no bankruptcy, reorganization or arrangement proceedings pending, being contemplated by or, to any Seller’s Knowledge, threatened against any Seller or Drilling Partnership or affecting any Seller’s or Drilling Partnership’s ability to sell any of the Properties or enter into the transactions contemplated by this Agreement.

After giving effect to the transactions contemplated by this Agreement, including payment of the Purchase Price, payment of all amounts required to be paid in connection with the consummation of the transactions contemplated hereby and payment of all related fees and expenses, each Seller will be Solvent as of the Closing and immediately following the Closing. For purposes of this Section 7.26, “Solvent” with respect to each Seller means that, as of any date of determination, (a) the amount of the “fair saleable value” of the assets of such Seller and its subsidiaries, taken as a whole, exceeds, as of such date, the sum of (1) the value of all “liabilities of such Seller and its subsidiaries, taken as a whole, including contingent and other liabilities,” as of such date, as such quoted terms are generally determined in accordance with the applicable federal and state Laws governing determinations of the insolvency of debtors, including applicable fraudulent transfer Laws, and (2) the amount that will be required to pay the probable liabilities of such Seller and its subsidiaries, taken as a whole on its existing debts (including contingent and other liabilities) as such debts become absolute and mature; (b) such Seller will not have, as of such date, an unreasonably small amount of capital for the operation of the business in which it is engaged or proposed to be engaged following the Closing Date; and (c) such Seller will be able to pay its liabilities, including contingent and other liabilities, as they mature.

Sellers’ prepackaged joint plan of reorganization (the “Plan”) was confirmed pursuant to the Bankruptcy Court’s order dated August 26, 2016. The Plan became effective on September 1, 2016, and as a result, the Plan has been substantially consummated. The Plan is binding on all parties whose claims or interests were affected thereunder and vested Sellers with all right, title and interest in the Properties being transferred under the Agreement. The Bankruptcy Case was closed by order of the Bankruptcy Court dated October 20, 2016 and no order entered by the Bankruptcy Court in the Bankruptcy Case is subject to any appeal.

(ii) As of the Closing, each Drilling Partnership will be governed by a partnership agreement substantially similar in all material respects to the partnership agreement of the Existing Partnership, provided the new partnership agreements for the newly formed Drilling Partnerships shall include equitable adjustments to the provisions thereof to reflect a recalculation of the general partner’s subordination obligations for the Reorganization Wells.

upon the actual historical net revenue of the Reorganization Wells in an Existing Partnership relative to (a) capital invested for the Reorganization Wells and (b) the return threshold in the applicable partnership agreement.

(iii) As of the Closing (or delayed closing, as applicable), the Reorganization Documents (as defined in subsection (x) below) will have been duly executed and delivered on behalf of the Drilling Partnerships and will constitute (and the Operative Documents to which any Drilling Partnership is a party, when executed and delivered at such closing, will constitute) a legal, valid and binding obligation of the Drilling Partnerships, enforceable against each Drilling Partnership in accordance with its and their respective terms, except as limited by bankruptcy or other similar Laws applicable generally to creditors’ rights and as limited by general equitable principles.

(iv) Immediately prior to the Closing, an Affiliate of Atlas Resources LLC will own, beneficially and of record all of the general partner interests in each Drilling Partnership, and such Affiliate shall not own any asset or have any Liability other than Equity Interests in the Drilling Partnerships. Schedule 7.28(iv) sets forth a true, complete and correct list of all of the Equity Interests (including general partner and limited partner interests) in the Existing Partnerships issued and outstanding as of the date hereof, and except as set forth on Schedule 7.28(iv), no Person holds any Equity Interests in the Existing Partnerships. Immediately prior to the Closing and except as set forth in the immediately preceding sentence, the Equity Interests in the post-Reorganization Drilling Partnerships will be identical to the Equity Interests in the Existing Partnerships that owned the applicable Reorganization Wells prior to the Reorganization, and no other Person will hold any Equity Interests in the post-Reorganization Drilling Partnerships.

(v) As of the Closing, (a) the post-Reorganization Drilling Partnerships will not own, directly or indirectly, any Equity Interests in any Person, any leasehold interest in any Lease, or any wells or related assets other than the Reorganization Wells and related Properties and (b) the Affiliate of Atlas Resources, LLC who owns the general partnership interests in the Drilling Partnerships will not own any Equity in any Person other than a Drilling Partnership.

(vii) As of the Closing, the pre-Reorganization Existing Partnerships’ interests in the Reorganization Wells will be owned by the post-Reorganization Drilling Partnerships.

(viii) The Reorganization will not conflict with, result in a breach of, constitute a default under or constitute an event that with notice or lapse of time, or both, would constitute a default under, accelerate or permit the acceleration of the performance required by, or except as set forth on Schedule 7.28(viii), require any consent,

authorization, waiver or approval of, any Third Party (including any limited partner of any Drilling Partnership) under, or be subject to any Preferential Rights under, any contract to which any Seller or any Drilling Partnership is a party. As of the Closing, Sellers and the Drilling Partnerships will have complied with all applicable securities Laws.

(ix) Except as set forth on Schedule 7.28(ix), the execution and delivery of the Reorganization Documents and the applicable deliverables required to be delivered pursuant to Section 14.2 by the managing general partner of each Drilling Partnership and the consummation of the Reorganization and transactions contemplated by this Agreement will not:

(a) conflict with or require the consent of any Person under any of the terms, conditions or provisions of the governing documents of such Existing Partnership or Drilling Partnership;

(b) violate any provision of, or require any consent or approval under any Laws applicable to such Existing Partnership or Drilling Partnership (except for consents and approvals of Governmental Authorities customarily obtained subsequent to transfer); or

(c) result in the creation or imposition of any lien or encumbrance upon one (1) or more of the Properties other than a Permitted Encumbrance.

(x) As of the Closing, Sellers have provided Buyer with true, complete and correct copies of (A) the certificates of limited partnerships, partnership agreements and all amendments to any of the foregoing of the Existing Partnerships and the Drilling Partnership Agreements, (B) all documents required to complete the Reorganization, (C) all new contracts or other agreements to be entered into by the Drilling Partnerships in connection with the Reorganization, and (D) all documents submitted to any Third Party, including without limitation any Governmental Authority, in connection with the Reorganization (collectively, the “Reorganization Documents”).

Grant Thornton LLP is the independent registered public accounting firm for the Public Partnerships and has not resigned or been dismissed as independent registered public accountants of the Public Partnerships as a result of or in connection with any disagreement with any Public Partnership on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures. None of the Public Partnerships has any material liability of the type required to be reflected on a

consolidated balance sheet of such Public Partnership prepared in accordance with GAAP, except for (i) liabilities set forth on the most recent unaudited consolidated balance sheet of such Public Partnership included in the documents filed prior to the date hereof with the U.S. Securities and Exchange Commission (the “Partnership Balance Sheet Date”) or the notes thereto and (ii) liabilities that have arisen since the Partnership Balance Sheet Date in the ordinary course of business.

(xii) Since the Partnership Balance Sheet Date, (i) except for the Reorganization, the business of each Public Partnership has been conducted in the ordinary course consistent with past practices and (ii) there has not been any event, occurrence, development or state of circumstances or facts that has had or would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

Each Party agrees that, with respect to the representations and warranties of such Party contained in this Agreement, such Party shall have the continuing right until Closing to add, supplement or amend the Schedules to its representations and warranties with respect to any matter hereunder arising or discovered which, if existing or known at the date hereof or thereafter, would have been required to be set forth or described in such Schedules.

After the Closing, each Party shall (and shall cause its and its Affiliates’ management and employees to) reasonably cooperate with the other Party in good faith with respect to the provision of information (to the extent reasonably necessary and permissible) in connection with the matters set forth on Schedule 2.3.2(iv).

9.13.1 Sellers will provide to Buyer a copy of each Reorganization Document for Buyer’s review and comment prior to the earlier of (i) the execution and delivery of such Reorganization Document, (ii) the delivery of such Reorganization document to any Third Party, including any Governmental Authority, or (iii) the Closing.

9.13.2 If, as of the Closing Date, the Reorganization has not been completed with respect to any Reorganization Wells, then with respect to such Reorganization Wells, (i) the Equity Interests of the Existing Partnership that owns such Reorganization Wells, together with all Properties primarily related thereto, will not be conveyed to Buyer at Closing and will be deemed an Excluded Asset, (ii) the Purchase Price will be reduced by the applicable Allocated Values for such retained Properties, and (iii) Buyer will, and Sellers will cause the applicable Existing Partnerships to, execute a mutually agreed operating agreement whereby Buyer will assume day to day operation of the applicable Reorganization Wells; provided, however, if the Reorganization is completed with respect to such Reorganization Wells by September 30, 2017, then Sellers shall deliver such retained Properties at a delayed closing pursuant to the procedures in Section 9.13.3.

9.13.3 If any Properties are to be conveyed to Buyer pursuant to Section 9.13.2, then (i) such Properties shall be deemed to no longer be Excluded Assets and shall be Properties for all purposes under this Agreement, (ii) such Properties shall be conveyed on the date that is no more than thirty (30) days after the Reorganization is complete with respect to such Reorganization Wells, (iii) such Properties shall be conveyed pursuant to an assignment in the form of the Equity Interests Assignment and Conveyance (if applicable), subject to the terms and conditions of this Agreement (including the Effective Time) and (iv) simultaneously with such Equity Interests Assignment and Conveyance (if applicable), Buyer shall pay to Sellers the Allocated Values for such Properties as otherwise adjusted solely to the extent not duplicative of adjustments already made to the Purchase Price. Any survival periods relating to an Equity Interests Assignment and Conveyance (if applicable) at a delayed Closing shall begin to run on the date of such delayed Closing.

10.1 Notice of Casualty Loss Prior to Closing. If, between the date hereof and the Closing, any portion of the Properties are damaged or destroyed by fire or other casualty (not

including normal wear and tear, downhole mechanical failure or reservoir changes) or if any portion of the Properties are taken by condemnation or under the right of eminent domain and such damage, destruction or condemnation has an adverse effect on the value of the affected Properties in an amount that exceeds $1,000,000 (all of which are herein called “Casualty Loss” and are limited to property damage or taking only), Sellers shall notify Buyer promptly after Sellers learn of such event.

Each such offer will be at base salary or hourly base wage, as applicable, through the first anniversary of the Closing Date, are no less favorable than the base salary or hourly base wage, as applicable, of such Available Employee on the day immediately prior to the Closing Date (each such offer, a “Qualifying Offer of Employment”). Sellers shall have the right to review the documents evidencing Buyer’s offers of employment for compliance with the terms of this Agreement. The other terms of employment for any Available Employee to whom Buyer makes an offer of employment shall be on terms and conditions that are substantially comparable in the aggregate to the employee benefits provided by Buyer or its Affiliates to its similarly situated employees. No later than five (5) days prior to the Closing Date, Buyer shall notify Sellers as to each employee who has accepted Buyer’s Qualifying Offer of Employment, and each employee who has rejected Buyer’s Qualifying Offer of Employment.

11.1.3 From the date hereof through the Closing Date, all contact and communication with Available Employees shall be coordinated through the Sellers’ Human Resources department(s), which shall cooperate with Buyer in permitting Buyer or its Affiliate reasonable access to the Available Employees to communicate any information concerning employment offers and employment with Buyer.

11.2.1 All Transferring Employees shall cease to be eligible for active participation in all plans, programs and arrangements of the applicable Seller or its Affiliates relating to employee benefits (each a “Seller Plan”) as of the Closing Date. As of the Closing Date, each Transferring Employee shall be permitted to participate in the plans, programs, and arrangements of Buyer or its Affiliates relating to employee benefits (each a “Buyer Plan” and collectively, the “Buyer Plans”) for which he or she is eligible. In addition, and without limiting the generality of the foregoing, (i) for purposes of eligibility, vesting, and seniority (but not for benefit accrual) under any Buyer Plan, Buyer or its Affiliate shall cause each Transferring Employee to be credited with service with Sellers or their Affiliates as though such service was provided by Buyer or its Affiliate, except where such crediting would result in duplication of benefits and (ii) for purposes of each Buyer Plan providing medical, dental, pharmaceutical and/or vision benefits to any Transferring Employee, Buyer shall use Commercially Reasonable Efforts to cause, to the extent allowable under applicable Law and the Buyer Plans, (A) all pre-existing condition exclusions and actively-at-work requirements of such Buyer Plan to be waived for such Transferring Employee and his or her covered dependents, and (B) cause any eligible expenses incurred by such Transferring Employee and his or her covered dependents during the portion of the plan year of the applicable Seller Plan ending on the date such Transferring Employee’s participation in the corresponding Buyer Plan begins to be taken into account under such Buyer Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such Buyer Plan.

11.2.2 As soon as administratively practicable following the Closing Date, a defined contribution plan of Buyer or its Affiliate that includes a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code (the “Buyer 401(k) Plan”) shall accept a rollover by Transferring Employees of any “eligible rollover distribution” (within the meaning of Section 402(c)(4) of the Code) from any Seller Plan that is a 401(k) savings plan, including plan loans, in accordance with applicable Code requirements for such rollovers.

11.2.3 As soon as reasonably practicable following the Closing Date, the applicable Seller shall pay to each Transferring Employee, in a lump sum, the amount of any unused paid time off accrued by such Transferring Employee as of the Closing Date under such Seller’s paid time off policy.

Any items not agreed to at the end of the 15-day period may, upon either Party’s written request, be resolved by arbitration in accordance with Section 16.2.2.

16.2.2 If the Parties do not agree upon the Final Settlement Statement, the Parties will promptly submit the disputed matters to the Independent Accounting Firm, which will act as an arbitrator and promptly decide all points of disagreement with respect to the Final Settlement Statement.

The Independent Accounting Firm will act for the limited purpose of determining the specific disputed matters submitted by either Party and may not award damages or penalties to either Party with respect to any matter. The Independent Accounting Firm’s decision will be final and binding on the Parties and shall not be subject to appeal or further review.

18.2.4 Notwithstanding any provision of this Agreement to the contrary, Section 18.2.1, Section 18.2.2 and Section 18.2.3 shall not apply to Sellers’ indemnification obligations for any breach of Sellers’ (i) representations and warranties in Section 7.1, Section 7.2, Section 7.3, Section 7.4, Section 7.7, Section 7.18 and Section 7.28, which shall survive Closing indefinitely, (ii) representations and warranties in Section 7.15 and covenants with respect to Taxes in Article 19, which shall survive the Closing for the applicable statute of Tax limitations plus 30 days, and (iii) covenants in Article 17, which shall survive the Closing in accordance with their respective terms.

18.2.5 Notwithstanding anything to the contrary contained in this Article 18, for the purposes of determining if there has been a loss resulting from the breach of any representation or warranty hereunder and the amount of the Claims in respect thereof, the representations and warranties shall, for purposes of this Article 18, be read without giving effect to any materiality, Material Adverse Effect or qualification with a similar meaning contained or incorporated directly or indirectly in such representation or warranty.

18.2.6 Sellers’ aggregate indemnification liability under this Agreement shall be limited to an amount equal to the Purchase Price.

18.2.7 Sellers shall not be required to indemnify and hold harmless Buyer Group for any Claim pursuant to Section 18.1 to the extent the matter giving rise to such Claim was taken into account in the computation of the Final Purchase Price.

18.3 Survival of Sellers’ Representations and Warranties. The representations and warranties made by Sellers in this Agreement shall survive Closing for the period contemplated by Section 18.2.1 and Section 18.2.4, and shall be actionable during such period (but not thereafter, excluding claims made in good faith prior to the end of such period) in accordance with this Article 18.

18.4 Buyer’s Indemnity. Except to the extent of Sellers’ Indemnification Obligations set forth in Section 18.1, after Closing, Buyer will release, defend, indemnify and hold harmless Seller Group, subject to and in accordance with this Article 18, from and against any and all Claims brought against or suffered by Seller Group arising from, relating to or connected with, directly or indirectly, any of the following:

18.4.1 any breach of the representations and warranties of Buyer in this Agreement (without giving effect to any materiality, Material Adverse Effect or qualification with a similar meaning contained or incorporated directly or indirectly in such representation or warranty);

18.5.1 Except as otherwise set forth in this Agreement or in the Conveyance, the Properties are being sold by Sellers to Buyer without warranty of any kind, express, implied, or statutory. Without limiting the generality of the immediately preceding sentence and except as set forth in this Agreement, Sellers convey the Properties as-is, where-is and with all faults and expressly disclaim and negate any implied or express warranty of (i) merchantability, (ii) fitness for a particular purpose, (iii) conformity to models or samples of materials and (iv) freedom from redhibitory vices or defects. Except as otherwise set forth in this Agreement, Sellers also expressly disclaim and negate any implied or express warranty at common law, by statute or otherwise relating to the accuracy of any of the information furnished with respect to the existence or extent of reserves or the value of the Properties based thereon, the condition or state of repair of any of the Properties; this disclaimer and denial of warranty also extends to the express or implied representation or warranty as to the prices Buyer and Sellers are or will be entitled to receive from production of Hydrocarbons from the Properties, it being understood that all reserve, price and value estimates upon which Buyer has relied or is relying have been derived by the individual evaluation of Buyer. Buyer hereby waives any warranty or representation, express or implied, with respect to the

accuracy, completeness or materiality of the information, reports, projections, materials, records, and data now, heretofore, or hereafter furnished or made available to Buyer in connection with the Properties, except as set forth in this Agreement (including any description of the quality or quantity of Hydrocarbon reserves (if any), production rates, recompletion opportunities, decline rates, pricing assumptions, ability or potential for production of Hydrocarbons from the Properties, Environmental Condition of the Properties, or any other matters contained in any other material furnished or made available to Buyer by Sellers or by any Sellers’ agent or representatives). Other than as set forth in this Agreement, any and all such information, reports, projections, materials, records, and data now, heretofore or hereafter furnished by Sellers is provided as a convenience only and any reliance on or use of same is at Buyer’s sole risk. Without limiting the foregoing, other than as set forth in this Agreement, Buyer hereby releases and disclaims any and all causes of action that Buyer may have against any Seller with respect to any Environmental Condition or any other rights that Buyer may have against any Seller pursuant to any Environmental Law, including any right of contribution or claim for response costs pursuant to CERCLA. With respect to the Surface Interests, Sellers expressly disclaim any representations or warranties that they are contiguous, that the Facilities lie within the Surface Interests, or that they grant the right to lay, maintain, repair, replace, operate, construction, or remove any Facilities. Subject to the provisions of this Agreement, if necessary, Buyer shall secure its own rights and permits to operate and maintain any Facilities on the land of others at its own expense. There are no warranties that extend beyond the face of this Agreement, the Conveyance and the Reorganization Wells Warranty.

18.5.2 Buyer acknowledges and affirms that it has reviewed the foregoing disclaimer and other provisions and agrees that such disclaimer and provisions are “conspicuous.”

18.6 Notice of Claims. If a Claim is asserted against a Party for which the other Party may have an obligation of indemnity and defense (whether under this Article 18 or any other provision of this Agreement), the Party seeking indemnification (“Indemnified Party”) shall give the Party from which the Indemnified Party seeks indemnification (“Indemnifying Party”) prompt written notice of the Claim, setting forth the particulars associated with the claim (including a copy of the written Claim, if any) as then known by the Indemnified Party (“Claim Notice”); provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party will relieve the Indemnifying Party of any liability or obligation hereunder, except to the extent that the Indemnifying Party clearly demonstrates that the defense of any third party suit, action or proceeding has been materially prejudiced by the Indemnified Party’s failure to promptly give such notice.

18.7 Defense of Claims. Within 30 days after the Indemnifying Party receives a Claim Notice, the Indemnifying Party shall notify the Indemnified Party whether or not the Indemnifying Party will assume responsibility for defense and payment of the Claim. The Indemnified Party is authorized, prior to and during such 30-day period, to file any motion, pleading or other answer that it deems necessary or appropriate to protect its interests, or those of the Indemnifying Party, and that is not prejudicial to the Indemnifying Party. If the

Indemnifying Party elects not to assume responsibility for defense and payment of the Claim, the Indemnified Party may defend against, or enter into any settlement with respect to, the Claim as it deems appropriate without relieving the Indemnifying Party of any indemnification obligations the Indemnifying Party may have with respect to such Claim. The Indemnifying Party’s failure to respond in writing to a Claim Notice within the 30-day period shall be deemed an election by the Indemnifying Party not to assume responsibility for defense and payment of the Claim. If the Indemnifying Party elects to assume responsibility for defense and payment of the Claim: (i) the Indemnifying Party shall defend the Indemnified Party against the Claim with counsel of the Indemnifying Party’s choice (reasonably acceptable to the Indemnified Party, which shall cooperate with the Indemnifying Party in all reasonable respects in such defense), (ii) the Indemnifying Party shall pay any judgment entered or settlement with respect to such Claim, (iii) the Indemnifying Party shall not consent to entry of any judgment or enter into any settlement with respect to the Claim that (a) does not include a provision whereby the plaintiff or claimant in the matter releases the Indemnified Party from all liability with respect to the Claim or (b) contains terms that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity), and (iv) the Indemnified Party shall not consent to entry of any judgment or enter into any settlement with respect to the Claim without the Indemnifying Party’s prior written consent. In instances where an actual conflict arises between the Indemnifying Party and the Indemnified Party, the Indemnified Party may employ separate counsel and participate in defense of a Claim and the Indemnified Party shall bear all fees and expenses of counsel employed by the Indemnified Party.

18.8 Scope of Remedies. Upon the Closing (or any delayed closing if applicable), the indemnities set forth in this Agreement shall become the exclusive remedy under, arising out of or relating to this Agreement, whether based in contract, tort, strict liability, statute, common law or otherwise; provided, however, that the foregoing shall not in any way limit Sellers’ liability with respect to Sellers’ special warranty of title set forth in the Conveyance and in the Reorganization Wells Warranties. Notwithstanding the foregoing, nothing in this Section 18.8 is intended to limit the rights of the Parties under applicable Laws in the event of fraud or intentional misrepresentation.

18.9 Extent of Indemnification. Without limiting or enlarging the scope of the indemnification, defense, release, disclaimer and assumption provisions set forth in this Agreement, to the fullest extent permitted by Law, an Indemnified Party shall be entitled to indemnification pursuant to the provisions of this Article 18 in accordance with the terms hereof, regardless of whether the indemnifiable loss giving rise to any such indemnification obligation is the result of the sole, active, passive, concurrent or comparative negligence, strict liability, breach of duty (statutory or otherwise), or other fault or violation of any Law of or by any such Indemnified Party, or any pre-existing defect; provided, that no such indemnification shall be applicable to the extent that gross negligence or willful misconduct of the Indemnified Party caused or contributed to the indemnifiable loss.

18.10 Tax Treatment of Indemnification Payments. Except as otherwise required by applicable Law, the Parties shall treat any indemnification payment made hereunder as an adjustment to the Purchase Price.

19.1 Responsible Party. All Taxes attributable to the ownership or operation of the Properties prior to the Effective Time are Sellers’ responsibility and all deductions, credits or refunds pertaining to the aforementioned Taxes, no matter when received, belong to Sellers. All Taxes attributable to the ownership or operation of the Properties on or after the Effective Time (excluding Sellers’ income taxes, franchise taxes or margin taxes through Closing, and excluding income or capital gains taxes from the sale of the Properties) are the responsibility of Buyer, and all deductions, credits or refunds pertaining to the aforementioned Taxes, no matter when received, belong to Buyer. Property Taxes not based on production shall be prorated based on a percentage of the assessment period occurring before the Effective Time. Property Taxes based on production (other than Severance Taxes) shall be deemed by the Parties to apply to production in the Tax period for which the Tax is levied. The Parties shall estimate all Taxes (excluding Sellers’ income taxes, franchise taxes or margin taxes) attributable to the ownership or operation of the Properties to the extent they relate to the period on and after the Effective Time and prior to Closing and incorporate such estimate into the Preliminary Settlement Statement. The actual amounts (to the extent the same differ from the estimate included in the Preliminary Settlement Statement) shall be accounted for in the Final Settlement Statement. All Tax Returns required to be filed with respect to the Properties and the Drilling Partnerships for a Taxable period ending prior to the Effective Time shall be filed by Sellers. Each Party shall consult in good faith with the other Party regarding any Tax Returns required to be filed by the other Party after the Effective Time that include periods starting before the Effective Time and ending after the Effective Time. Unless required by applicable Law, (i) no amended Tax Return with respect to a Pre-Closing Tax Period shall be filed by or with respect to the Properties and (ii) no Tax election shall be made what has retroactive effect on or with respect to Sellers or the Properties for any Pre-Closing Tax period, without the prior written consent of Sellers.

19.2 Transfer Taxes. Notwithstanding anything to the contrary herein, it is acknowledged and agreed by and between Sellers and Buyer that the Purchase Price excludes any sales taxes or other Taxes of a similar nature in connection with the sale of property pursuant to this Agreement. Buyer and Sellers will use Commercially Reasonable Efforts and cooperate in good faith to exempt the sale, conveyance, assignments and transfers to be made to Buyer from any sales, use, stamp, real estate transfer, documentary, registration, recording and other similar Taxes (each a “Transfer Tax”). If a determination is ever made that a Transfer Tax applies, Buyer will bear such Transfer Tax. If a determination is made that a Transfer Tax results from the Reorganization, Sellers will bear such Transfer Tax.

19.3 Allocation of Values. Sellers and Buyer agree that the transaction under this Agreement is subject to the reporting requirement of Code Section 1060 and, therefore IRS Form 8594 (Asset Acquisition Statement Under Section 1060) is required to be and will be filed for this transaction. No later than 30 days after receipt of the Final Settlement Statement, Sellers will prepare a draft Form 8594 and deliver a copy thereof to Buyer. Thereafter, Sellers and Buyer will confer and cooperate in good faith in the preparation and filing of their respective forms to reflect a consistent reporting of the agreed upon allocation. In the event that the allocation is disputed by any Taxing authority, the Party receiving notice of such dispute will promptly notify and consult with the other Party in good faith and keep the other Party apprised of material developments concerning resolution of such dispute.

19.4 Tax Contests. Each Party shall have the right, at its sole expense, to control any audit or examination by any Taxing authority, initiate any claim for refund, and contest, resolve and defend against any assessment, notice of deficiency, or other adjustment or proposed adjustment relating to Taxes (“Tax Contest”) for any periods for which such Party has sole responsibility under this Agreement (treating, solely for this purpose, all of the Sellers as a single party). If a Tax Contest relates to Taxes and periods for which both the Buyer and one or more Sellers are so responsible, the Parties will consult in good faith to determine whether joint control can be effected (or if not which Party has the greater amount at risk for such periods and thus should control) and how to keep all Parties informed of all developments. Each non-controlling Party agrees to cooperate with the controlling Party with respect to any Tax Contest, as and to the extent reasonably requested by such controlling Party, and shall furnish or cause to be furnished to such controlling Party, upon request, as promptly as practicable and at the controlling Party’s expense, such information and assistance relating to such Tax Contest (including access to books and records) as is reasonably necessary for the preparation for any Tax Contest. The controlling Party shall not settle, compromise or otherwise resolve any audit, examination, assessment or other adjustment or proposed adjustment relating to any Taxes for which another Party has any responsibility under this Agreement without such other Party’s prior written consent, which shall not be unreasonably withheld.

20.1 Notice. All notices required or permitted under this Agreement must be in writing and delivered personally, by email (with written confirmation of delivery) or by certified mail, postage prepaid and return receipt requested as follows:

or to such other place within the United States of America as either Party may designate as to itself by written notice to the other. All notices given by personal delivery or mail will be effective on the date of actual receipt at the appropriate address or on the date receipt is rejected at such address.

20.2 Governing Law. This Agreement, the obligations of the Parties under this Agreement and all other matters arising out of or relating to this Agreement and the transactions it contemplates, will be governed by and construed in accordance with the Laws of the State of Texas, without giving effect to any conflicts of law principles that would cause the laws of another jurisdiction to apply. Any dispute arising out of or relating to this Agreement which cannot be amicably resolved by the Parties, shall be brought in a federal or state court of competent jurisdiction sitting in Harris County of the State of Texas, and the Parties irrevocably submit to the jurisdiction of any such court solely for the purpose of any such suit, action or proceeding.

20.3 Assignment. This Agreement will be binding upon and will inure to the benefit of the Parties and their respective permitted successors and assigns. Notwithstanding the preceding sentence, except as permitted below, prior to Closing neither Party may assign this Agreement or its rights under this Agreement or delegate any performance obligations under this Agreement without the other Party’s written consent, which will not be unreasonably withheld. Buyer will, without the obligation to obtain the prior written consent of Sellers but with the obligation to provide contemporaneous or prior notice to Sellers, be entitled to assign this Agreement or all or any part of its respective rights or and delegate its respective performance

obligations under this Agreement to one or more Affiliates of Buyer, but no such assignment will release or discharge Buyer from any of its obligations as the “Buyer” under this Agreement or any certificate, document, instrument or writing delivered pursuant hereto. Any purported assignment or delegation in violation of this Section 20.3 will provide the non-assigning Party the right to void the assignment ab initio.

20.4 Entire Agreement. This Agreement, together with (i) the Exhibits and Schedules hereto, (ii) the certificates, documents, instruments and writings that are delivered pursuant hereto, (iii) the Reorganization Documents, and (iv) the Confidentiality Agreement, dated January 25, 2017, between Titan Energy Operating, LLC and Four Pines Minerals, LLC (the “Confidentiality Agreement”), constitute the entire, complete and exclusive agreement and understanding of the Parties in respect of its respective subject matters and expressly supersedes all prior understandings, agreements or representations by or among the Parties, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby. The provisions of this Agreement may not be explained, supplemented or qualified through evidence of trade usage or a prior course of dealings. In entering into this Agreement, neither Party has relied upon a statement, representation, warranty or agreement of the other Party except for those expressly contained in this Agreement.

20.5 Amendment; Waiver. No amendment, modification, replacement, rescission, termination or cancellation of any provision of this Agreement will be valid, unless the same is in writing and signed by Buyer and each Seller. No waiver by either Party of any default, misrepresentation or breach of warranty or covenant under this Agreement or course of dealing between the Parties, whether intentional or not, will extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant under this Agreement or affect in any way any rights arising because of any prior or subsequent such occurrence. No single or partial exercise of any right or remedy under this Agreement precludes the simultaneous or subsequent exercise of any other right or remedy.

20.6 Severability. If any term or other provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by applicable Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties to the greatest extent legally permissible.

20.7 Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the Parties and no presumption or burden of proof will arise favoring or disfavoring either Party because of the authorship of any provision of this Agreement. The Parties will treat the words “include,” “includes” and “including” as if followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. All references to “$” or

“dollars” shall be deemed references to U.S. dollars. Where a date or time period is specified, it will be deemed inclusive of the last day in such period or the date specified, as the case may be. Unless expressly provided to the contrary, the word “or” is not exclusive. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The words “this Article,” “this Section,” “this subsection,” “this clause,” and words of similar import, refer only to the Article, Section, subsection and clause hereof in which such words occur. References herein to any Section or Article are references to a Section or Article of this Agreement unless the context clearly requires otherwise.

20.8 Headings. The Article and Section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

20.9 Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which the Parties will treat as an original but all of which together will constitute one and the same instrument. The signatures of all the Parties need not appear on the same counterpart and delivery of an executed counterpart signature page of this Agreement (including by means of facsimile or email attaching a copy in portable document format (.pdf)) will be equally as effective as delivery of an original executed counterpart of this Agreement in the presence of the other Party. This Agreement is effective on the delivery of one (1) executed counterpart from each Party to the other Party.

20.10 Expenses and Fees. Except as expressly set forth herein, each Party will pay its own fees and expenses incident to the negotiation and preparation of this Agreement and consummation of the transactions contemplated hereby, including brokers’ fees. Sellers will be solely responsible for all costs and expenses of the Reorganization. Buyer will be responsible for the cost of all fees for the recording of transfer documents. The Party incurring any other costs will bear them.

20.11 Limitation on Damages. NOTWITHSTANDING ANY TERM OR PROVISION OF THIS AGREEMENT TO THE CONTRARY, IN NO EVENT WILL EITHER PARTY TO THIS AGREEMENT BE LIABLE TO THE OTHER PARTY FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, EXEMPLARY, PUNITIVE OR SIMILAR DAMAGES ARISING OUT OF OR RELATING TO THIS AGREEMENT, EXCEPT TO THE EXTENT ANY SUCH PARTY WAS REQUIRED TO PAY SUCH DAMAGES TO A THIRD PARTY IN CONNECTION WITH A CLAIM, IN WHICH EVENT SUCH DAMAGES SHALL BE RECOVERABLE HEREUNDER.

20.12 Third Party Beneficiaries. Nothing contained in this Agreement entitles anyone other than Buyer or Sellers or their respective permitted successors and assigns to any rights under this Agreement, except with respect to waivers and indemnities that expressly provide for waivers or indemnification of Seller Group, Buyer Group or another Person, in which case members of such groups and such other Persons are considered third party beneficiaries for the sole purposes of those waiver and indemnity provisions and are bound by the procedures and limitations therein. The immediately preceding sentence notwithstanding, any claim for indemnity or defense under this Agreement may only be brought and administered by a Party to

this Agreement. Each Party may elect to exercise or not exercise the indemnification and defense rights under this Agreement on behalf of any member of Seller Group or Buyer Group, as applicable, and no member of any such group shall have any rights under this Agreement except to the extent exercised on its or his behalf by Sellers or Buyer, as the case may be.

20.13 Survival of Certain Obligations. Except as expressly provided otherwise in this Agreement, (i) waivers, disclaimers, releases and obligations of indemnity and defense contained in this Agreement will survive the Closing in accordance with their terms, and (ii) to the extent performable after Closing, covenants contained in this Agreement (including any covenants set forth in Article 9 and Article 17) will survive Closing.

20.14 Bulk Transfer Laws. Buyer hereby waives compliance by Sellers with the provisions of any so-called bulk transfer laws of any jurisdiction in connection with the transfer and conveyance of the Properties. For the avoidance of doubt, the term “bulk transfer laws” in this Section 20.14 shall not include any tax clearance or similar provisions.

20.15 Schedules. Any matter disclosed in any Section of the Schedules shall be considered disclosed with respect to each other Section of this Agreement to the extent the relevance thereto is reasonably apparent on its face. The inclusion of information in any Section of the Schedules shall not be construed as an admission that such information is material or that such matter actually constitutes compliance with, or a violation of, any Law, Permit, Contract or Lease or other topic to which such disclosure is applicable.

20.16 Conspicuousness. Each of the Parties hereto specifically acknowledges and agrees (i) that it has a duty to read this Agreement and that it is charged with notice and knowledge of the terms hereof, and (ii) that it has in fact read this Agreement and is fully informed and has full notice and knowledge of the terms, conditions and effects of this Agreement. Each Party hereto further agrees that it will not contest the validity or enforceability of any such provisions of this Agreement on the basis that the Party had no notice or knowledge of such provisions or that such provisions are not “conspicuous”. The Parties expressly hereby acknowledge and agree that the provisions contained in this Agreement that are set out in “bold” or in “ALL CAPS” satisfy the requirement of the “express negligence rule” and any other requirement at law or in equity that provisions contained in a contract be conspicuously marked or highlighted.

20.17 Sellers’ Representative. Each of the Sellers hereby irrevocably confirm, designate and appoint Betsy Toney, and to the extent she is not available, Joel Heiser, as their representative, agent and attorney-in-fact, with exclusive power and authority to act for and on behalf of each Seller in connection with its rights and obligations in this Agreement. This appointment and grant of authority to Betsy Toney, and to the extent she is not available, Joel Heiser will be binding upon the legal representatives, successors and assigns of each Seller. All actions and decisions of Betsy Toney, and to the extent she is not available, Joel Heiser in connection with this Agreement will be binding upon each Seller, and no Seller will have the right to object, dissent, protest or otherwise contest such actions or decisions.

IN WITNESS WHEREOF, the Parties have executed this Agreement as of the date first set forth above.
