The share of each adjustment allocated to a particular Property shall be obtained by allocating that adjustment among the various Properties on a pro-rata basis in proportion to the Unadjusted Purchase Price allocated to each such Property on Schedule 2.2. Seller has accepted such Allocated Values for purposes of this Agreement and the transactions contemplated hereby, but otherwise makes no representation or warranty as to the accuracy of such values.

oil Hydrocarbons, on the basis of $42.20, multiplied by the amount of the imbalance in barrels; or (C) by an amount agreed to in writing by the Parties;

(d)increased by the aggregate amount of Seller’s share of any merchantable Hydrocarbon inventories produced from or credited to the Properties in storage tanks included in the Assets upstream of delivery points to the relevant purchasers on the Effective Time based on the quantities in such storage tanks as of the Effective Time as measured by and reflected in Seller’s records, multiplied by (A) in the case of gaseous Hydrocarbons, $1.74, (as adjusted for MMBtu content in the case of natural gas liquids), or (B) in the case of oil Hydrocarbons, multiplied by $42.20;

(e)increased by the net amount of all prepaid expenses other than Taxes with respect to the Assets attributable to periods from and after the Effective Time (including bonuses; rentals; and cash calls to third Person operators) which have been paid or economically borne by Seller or its Affiliates;

(f)without limiting either Party’s rights under Article 11, adjusted for proceeds and other income attributable to the Assets, Property Costs, and certain other costs attributable to the Assets as follows:

(i)decreased by an amount equal to the aggregate amount of the following proceeds received by Seller or its Affiliates:

(B)other income earned with respect to the Assets attributable to the periods from and including the Effective Time and excluding the effects of any Hedges, futures, options, swaps, or other derivatives;

(ii)increased by an amount equal to the amount of all Property Costs which are incurred in the ownership and operation of the Assets from and after the Effective Time but paid or economically borne by or on behalf of Seller or any of its Affiliates on or prior to the Cut-Off Date, except in each case any costs already deducted in the determination of proceeds in Section 2.3(f)(i); and

(iii)decreased by the amount of all positive Purchaser Responsibility Suspense Amounts, to the extent such positive Purchaser Responsibility Suspense Amounts are not transferred to Purchaser’s control at the Closing;

(g)adjusted for Asset Taxes, determined by utilizing the most recent information available, as follows:

(i)increased by the amount of Asset Taxes allocated to Purchaser pursuant to Section 9.1 but paid or otherwise economically borne by Seller (or any of its Affiliates) (excluding, for the avoidance of doubt, any Asset Taxes that were withheld or deducted from, or otherwise netted against, the gross amount paid or payable to Seller in connection with a transaction to which Section 2.3(f) applies, and therefore were taken into account in determining the proceeds “received” by Seller for purposes of applying Section 2.3(f) with respect to such transaction); and

(ii)decreased by the amount of all Asset Taxes allocated to Seller in accordance with Section 9.1 but paid or otherwise economically borne by Purchaser (or any of its Affiliates);

(h)with respect to overhead costs of Seller incurred from the Effective Time to the Closing Date, increased by an amount equal to:

(i)with respect to any Assets subject to a joint operating agreement, that which would be chargeable by Seller for its overhead costs pursuant to such existing joint operating agreements with respect to Seller’s interest in such Assets; and

(ii)with respect to any Assets not subject to a joint operating agreement, (A) for each horizontal Well, a drilling well rate of Eight Thousand Dollars ($8,000) per month (prorated for less than a full month) and a producing well rate of Eight Hundred Dollars ($800) per month and (B) for each vertical Well, a drilling well rate of Six Thousand Dollars ($6,000) per month (prorated for less than a full month) and a producing well rate of Six Hundred Fifty Dollars ($650) per month; and

(i)decreased or increased, as applicable, for any other amount provided for in this Agreement or agreed upon by Seller and Purchaser in writing.

The amount of each adjustment to the Unadjusted Purchase Price described in Section 2.3(f) shall be determined in accordance with Accounting Principles using the accrual method of accounting and COPAS, as consistently applied.

2.4    Certain Ordinary-Course Costs and Revenues.

(a)With respect to revenues earned or Property Costs incurred with respect to the Assets prior to the Effective Time but received or paid after the Effective Time:

(i)Seller shall be entitled to all amounts earned from the sale, during the period up to but excluding the Effective Time, of Hydrocarbons produced from, or attributable to, the Properties, which amounts are received prior to the Cut-Off Date (net of any (A) Royalties; (B) gathering, processing, and transportation costs paid in connection with sales of Hydrocarbons that are not included as Property Costs under Section 2.4(a)(ii); and (C) Property Costs that are deducted by the purchaser of production), and to all other income earned with respect to the Assets up to but excluding the Effective Time and received on or before the Cut-Off Date.

(ii)Seller shall be responsible for (and entitled to any refunds and indemnities with respect to) all Property Costs incurred prior to the Effective Time; provided, however, that Seller’s responsibility for the foregoing shall terminate on the Cut-Off Date.

(b)Purchaser shall be entitled to all amounts earned from the sale, during the period from and after the Effective Time, of Hydrocarbons produced from, or attributable to, the Properties, and to all other income earned with respect to the Assets from and after the Effective Time, and shall be responsible for (and entitled to any refunds and indemnities with respect to) all Property Costs incurred from and after the Effective Time.

(c)Notwithstanding anything in this Agreement to the contrary, without duplication of any adjustments made pursuant to Section 2.3(f), should Purchaser or any Affiliate of Purchaser receive after Closing any proceeds or other income to which Seller is entitled under Section 2.4(a), Purchaser shall fully disclose, account for, and promptly remit the same to Seller.

(d)Notwithstanding anything in this Agreement to the contrary, without duplication of any adjustments made pursuant to this Article 2, should Seller or any Affiliate of Seller receive after Closing any amounts earned from the sale of Hydrocarbons produced from, or attributable to, the Properties or other income earned with respect to the Assets for the period of time from and after the Effective Time, Seller shall fully disclose, account for, and promptly remit the same to Purchaser.

(e)Seller shall have no further responsibility for Property Costs incurred with respect to the Assets, to the extent such amounts have not been received or paid, respectively, on or before the Cut-Off Date.

2.5    Procedures.

(a)All adjustments and payments made pursuant to this Article 2 shall be without duplication of any other amounts paid or received under this Agreement.

(b)For purposes of allocating production (and accounts receivable with respect thereto) under Section 2.3 and Section 2.4, (i) liquid Hydrocarbons shall be deemed to be “from or attributable to” the Properties when they pass through the pipeline flange connecting into the tank batteries related to each Well, and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Properties when they pass through the delivery point sales meters or similar meters at the point of entry into the pipelines through which they are transported. Seller shall use reasonable interpolative procedures to arrive at an allocation of production when exact meter readings or gauging or strapping data are not available.

(c)Surface use or damage fees and other Property Costs that are paid periodically shall be prorated based on the number of days in the applicable period falling before, or on or after, the Effective Time.

Each Party shall provide the other with a copy of all applicable audit reports and written audit agreements received by such Party and relating to periods for which Seller is partially responsible.

(e)“Earned” and “incurred,” as used in Section 2.3 and Section 2.4, shall be interpreted in accordance with accounting recognition guidance under the Accounting Principles.

2.6    Additional Consideration.

(a)If the Closing occurs, Purchaser shall pay to Seller as part of the Purchase Price Additional Consideration Payments up to an aggregate sum of 23 ###-###-####% of the Unadjusted Purchase Price (which in the case of this Agreement is an amount equal to Sixty Million Dollars ($60,000,000)) (the “Additional Consideration Cap”), subject to the terms and conditions of this Section 2.6. For the avoidance of doubt, Purchaser shall have no liability or obligation to make any Additional Consideration Payments to Seller in excess of the Additional Consideration Cap and, if at any time, Seller has received aggregate Additional Consideration Payments equal to the Additional Consideration Cap, then Purchaser shall have no further obligations or liabilities under this Section 2.6.

(b)The “2019 Additional Consideration Payment”, if any, shall be calculated as follows: if the 2019 WTI Price is (i) less than Sixty Dollars ($60) per barrel, there shall not be any 2019 Additional Consideration Payment; (ii) equal to or greater than Sixty Dollars ($60) per barrel but less than Sixty-Five Dollars ($65) per barrel, the 2019 Additional Consideration Payment shall be an amount equal to 3.46153846% of the Unadjusted Purchase Price (which in the case of this Agreement is an amount equal to Nine Million Dollars ($9,000,000)); or (iii) equal to or greater than Sixty-Five Dollars ($65) per barrel, the 2019 Additional Consideration Payment shall be an amount equal to ###-###-####% of the Unadjusted Purchase Price (which in the case of this Agreement is an amount equal to Twenty Million Eight Hundred Thirty-Three Thousand Three Hundred Thirty-Three Dollars and 33/100 ($20,833,333.33)).

(c)The “2020 Additional Consideration Payment”, if any, shall be calculated as follows: if the 2020 WTI Price is (i) less than Sixty Dollars ($60) per barrel, there shall not be any 2020 Additional Consideration Payment; (ii) equal to or greater than Sixty Dollars ($60) per barrel but less than Sixty-Five Dollars ($65) per barrel, the 2020 Additional Consideration Payment shall be an amount equal to 3.46153846% of the Unadjusted Purchase Price (which in the case of this Agreement is an amount equal to Nine Million Dollars ($9,000,000)); or (iii) equal to or greater than Sixty-Five Dollars ($65) per barrel, the 2020 Additional Consideration Payment shall be an amount equal to ###-###-####% of the Unadjusted Purchase Price (which in the case of this Agreement is an amount equal to Twenty Million Eight Hundred Thirty-Three Thousand Three Hundred Thirty-Three Dollars and 33/100 ($20,833,333.33)).

(d)The “2021 Additional Consideration Payment” (and together with the 2019 Additional Consideration Payment and the 2020 Additional Consideration Payment, if any, the “Additional Consideration Payments”), if any, shall be calculated as follows: if the 2021 WTI Price is (i) less than Sixty Dollars ($60) per barrel, there shall not be any 2021 Additional Consideration Payment; (ii) is equal to or greater than Sixty Dollars ($60) per barrel but less than Sixty-Five Dollars ($65) per barrel, the 2021 Additional Consideration Payment shall be an amount equal to 3.46153846% of the Unadjusted Purchase Price (which in the case of this Agreement is an amount equal to Nine Million Dollars ($9,000,000)); or (iii) equal to or greater than Sixty-Five Dollars ($65) per barrel, the 2021 Additional Consideration Payment shall be an amount equal to ###-###-####% of the Unadjusted Purchase Price (which in the case of this Agreement is an amount equal to Twenty Million Eight Hundred Thirty-Three Thousand Three Hundred Thirty-Three Dollars and 33/100 ($20,833,333.33)).

(e)Subject to the Additional Consideration Cap and to Sections 2.6(f) and 2.6(g), each Additional Consideration Payment, if any, shall be paid by Purchaser to Seller by wire transfer in immediately available funds within sixty (60) days after the last calendar day of the 2019, 2020 and 2021 calendar years, as applicable.

(f)Within ten (10) days after the last calendar day of each of the 2019, 2020 and 2021 calendar years, Purchaser shall deliver to Seller a statement setting forth Purchaser’s good faith calculation of the applicable Additional Consideration Payment (each, an “Additional Consideration Statement”). As soon as reasonably practicable, and in any event within ten (10) days after Seller’s receipt of an Additional Consideration Statement, Seller may return to Purchaser a written report containing any proposed changes to such Additional Consideration Statement (an “Additional Consideration Dispute Notice”). Any changes not so specified in a timely delivered Additional Consideration Dispute Notice shall be deemed waived, and Purchaser’s determinations with respect to all such elements of the applicable Additional Consideration Statement that are not addressed specifically in the Additional Consideration Dispute Notice shall prevail. If Seller fails to timely deliver an Additional Consideration Dispute Notice to Purchaser containing changes Seller proposes to be made to the applicable Additional Consideration Statement, the applicable Additional Consideration Statement as delivered by Purchaser will be deemed to be correct and will be final and binding on the Parties and not subject to further audit or arbitration.

(g)Seller and Purchaser shall work together in good faith to resolve any matters addressed in an Additional Consideration Dispute Notice. If Seller and Purchaser are unable to resolve all of the matters addressed in an Additional Consideration Notice within ten (10) Business Days after the delivery of such Additional Consideration Dispute Notice by Seller to Purchaser, either Party may notify the other Party of its election to submit such unresolved matters to arbitration and thereafter the Parties shall promptly submit all unresolved matters addressed in such Additional Consideration Dispute Notice to arbitration in accordance with this Section 2.6(g). Within ten (10) Business Days of a matter being submitted to arbitration in accordance with the preceding sentence, each Party shall (i) summarize its position with regard to such dispute and (ii) submit such summaries to a nationally-recognized independent accounting firm as selected by mutual agreement of the Parties (the “Additional Consideration Arbitrator”), together with the applicable Additional Consideration Dispute Notice, applicable Additional Consideration Statement, and any other documentation such Party may desire to submit. If the Parties cannot agree on an Additional Consideration Arbitrator within five (5) Business Days after a Party’s election to submit such matters to arbitration under this Section 2.6(g), then the Parties shall formally request the Houston, Texas office of the American Arbitration Association (or, if there is no such office, the office of the American Arbitration Association serving Houston, Texas) to select the Additional Consideration Arbitrator. Within ten (10) Business Days after receiving the Parties’ respective submissions, the Additional Consideration Arbitrator shall render a decision choosing either Seller’s position or Purchaser’s position with respect to each matter addressed in any Additional Consideration Dispute Notice, based on the materials described above. Any decision rendered by the Additional Consideration Arbitrator pursuant hereto shall be final, conclusive, and binding on Seller and Purchaser and enforceable against the Parties in any court of competent jurisdiction. The costs of the Additional Consideration Arbitrator shall be borne equally between Seller and Purchaser. Within ten (10) days after the Additional Consideration Arbitrator renders a decision pursuant to this Section 2.6(g), Purchaser shall pay to Seller the Additional Consideration Payment owing to Seller, if any, by wire transfer in immediately available funds.

(h)As used in Section 2.6, (i) the “2019 WTI Price” means the simple arithmetic average of the final monthly settlements for each month from January 2019 through December 2019 for NYMEX Light Sweet Crude Oil Futures, as reported by the CME Group Inc. (“CME”) under the “Settlements” tab, with the “Futures” choice selected, which chart can currently be accessed at the following link:https://www.cmegroup.com/trading/energy/crude-oil/light-sweet-crude_quotes_settlements_futures.html. For clarification, the simple arithmetic average of the 2019 WTI Price would be calculated by adding the twelve (12) final monthly settlements together and dividing the sum by twelve (12); (ii) the “2020 WTI Price” means the simple arithmetic average of the final monthly settlements for each month from January 2020 through December 2020 for NYMEX Light Sweet Crude Oil Futures, as reported by CME under the “Settlements” tab, with the “Futures” choice selected, which chart can currently be accessed at the following link:https://www.cmegroup.com/trading/energy/crude-oil/light-sweet-crude_quotes_settlements_futures.html. For clarification, the simple arithmetic average of the 2020 WTI Price would be calculated by adding the twelve (12) final monthly settlements together and dividing the sum by twelve (12); and (iii) the “2021 WTI Price” means the simple arithmetic average of the final monthly settlements for each month from January 2021 through December 2021 for NYMEX Light Sweet Crude Oil Futures, as reported by CME under the “Settlements” tab, with the “Futures” choice selected, which chart can currently be accessed at the following link:https://www.cmegroup.com/trading/energy/crude-oil/light-sweet-crude_quotes_settlements_futures.html. For clarification, the simple arithmetic average of the 2021 WTI Price would be calculated by adding the twelve (12) final monthly settlements together and dividing the sum by twelve (12). For the avoidance of doubt, the January 2019 settlement (settled December 19, 2018) was $47.20/barrel, the February 2019 settlement (settled January 22, 2019) was $52.57/barrel, the March 2019 settlement (settled February 20, 2019) was $56.92/barrel, and the April 2019 settlement (settled March 20, 2019) was $59.83/barrel.

(i)Any Additional Consideration Payments paid pursuant to this Section 2.6 shall be considered an adjustment to the Purchase Price for Tax purposes to the extent permitted by Law. Notwithstanding anything to the contrary, Purchaser shall have the right at the time payment is due pursuant to this Section 2.6 to set-off against, offset, recoup or withhold from the Additional Consideration Payments, if payable, in respect of any amounts that are conclusively due and payable to Purchaser by Seller pursuant to this Agreement, including any such amounts conclusively due and payable to Purchaser by Seller pursuant to the indemnification obligations under Article 11.

(j)The Parties acknowledge and agree that (i) the contingent rights to receive Additional Consideration Payments shall not be represented by any form of certificate or other instrument, are not transferable, except by operation of Law and as permitted by Section 12.9 of this Agreement, and do not constitute an equity or ownership interest in Purchaser or any of its respective Affiliates, (ii) Seller shall not have any rights as a securityholder of Purchaser or any of its Affiliates as a result of the contingent right to receive any Additional Consideration Payments hereunder, and (iii) no interest is payable with respect to any Additional Consideration Payments contemplated hereby.

(k)In the event Purchaser sells, transfers or otherwise disposes of the Assets in a transaction in which the acquirer of the Assets (or a group of affiliated acquirers) acquires all or substantially all of the assets of Purchaser (a “Subject Transaction”), then Purchaser shall be required to either:

(i)Cause such acquierer(s) to expressly assume in writing upon consummation of the Subject Transaction the covenants of this Section 2.6 that remain outstanding as of the time of such transaction; or

(ii)At any time prior to or contemporaneously with the consummation of the Subject Transaction, (A) procure a letter of credit in favor of Seller issued by a nationally recognized banking association (which shall include JPMorgan Chase Bank) or such other financial institution reasonably acceptable to Seller, in an amount equal to the Financial Assurance Amount and otherwise on customary terms and conditions; (B) deposit with a third party escrow agent, which shall be a nationally recognized banking association (which shall include JPMorgan Chase Bank) or such other financial institution reasonably acceptable to Seller, an amount equal to the Financial Assurance Amount pursuant to an escrow agreement on customary terms and conditions; or (C) procure such other credit support or financial assurance for the benefit of Seller in an amount equal to the Financial Assurance Amount that is reasonably acceptable to Seller (any of the foregoing described in clause (A), (B) or (C) or any combination thereof, the “Financial Assurance”). Any such Financial Assurance procured by Purchaser shall be required to be maintained in an aggregate amount (the “Financial Assurance Amount”) equal to the then aggregate amount of Additional Consideration that (as of the relevant time of determination) may become due and payable to Seller under this Section 2.6, taking into account the Additional Consideration Cap and any Additional Consideration Payments previously paid to Seller hereunder (or determined not to be due and payable to Seller hereunder). For clarity, the amount of the Financial Assurance Amount shall automatically be reduced (and any cash deposited by Purchaser pursuant thereto shall be promptly released to Purchaser) as and to the extent Additional Consideration Payments that become due and payable to Seller are actually paid to Seller or are no longer available to become due and payable to Seller, in each case, in accordance with this Agreement.

2.7    Withholding. Purchaser shall be entitled to deduct and withhold from any consideration otherwise payable or deliverable to Seller such amounts as required to be deducted or withheld therefrom under the Code, under any Tax law or pursuant to any other applicable Laws; provided that Purchaser will use commercially reasonable efforts to first notify Seller of its withholding obligation and provided further that Purchaser will cooperate in good faith with Seller to minimize, to the extent permissible under

applicable Law, the amount of any such deduction or withholding. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes as having been paid to the Person to whom such amounts would otherwise have been paid absent such deduction or withholding.

3.1    Purchaser’s Title Review.

(a)From and after the Execution Date, and pursuant and subject to the terms of Sections 6.1 and 6.5, Purchaser shall have the right to conduct a review of Seller’s title to the Assets. Without limiting Purchaser’s right to indemnification pursuant to Article 11 with respect to a breach of Sections 4.2, 4.4, 4.5, 4.9, 4.12, 4.13, 4.14, 4.18, 4.19, 6.4 or clauses (h) or (k) of the definition of “Retained Obligations”, the provisions of this Article 3, the special warranty of Defensible Title in the Assignment and Bill of Sale, and the condition to Closing in Section 7.2(d) provide Purchaser’s exclusive remedy with respect to any Title Defects or other deficiencies or defects in Seller’s title to the Properties.

(c)The Assignment and Bill of Sale to be executed and delivered by the Parties at Closing (the “Assignment and Bill of Sale”) shall be in the form attached hereto as Exhibit B, and shall contain a special warranty of Defensible Title to the Properties shown on Exhibit A‑1 and Exhibit A‑2 by, through or under Seller and its Affiliates, but not otherwise, subject to the Permitted Encumbrances. Purchaser shall be deemed to have waived all breaches of Seller’s special warranty of Defensible Title set forth in the Assignment and Bill of Sale for which Purchaser has not furnished to Seller a valid defect claim notice that satisfies the requirements set forth in Section 3.6(a)(i) through (v) on or before the date forty-eight (48) months after Closing. Purchaser shall not be entitled to protection under Seller’s special warranty of Defensible Title in the Assignment and Bill of Sale against any Title Defect (i) reported by Purchaser to Seller in a Title Defect notice delivered by Purchaser pursuant to Section 3.6(a) prior to the Defect Claim Deadline or (ii) for which Purchaser had actual knowledge of but did not submit a Title Defect notice to Seller regarding the same; provided, that Purchaser’s recovery under this Agreement for a Title Defect reported prior to the Defect Claim Deadline that would otherwise constitute a breach of Seller’s special warranty of Defensible Title contained in any Assignment and Bill of Sale shall not be subject to the individual claim threshold set forth in Section 3.9(a)(viii)(A) or the deductible set forth in Section 3.9(a)(viii)(C). If Purchaser provides written notice of a breach of the special warranty to Seller, Seller shall have a reasonable opportunity to cure such breach.

If Seller or any of its Affiliates is not the operator of a Property, Seller shall use commercially reasonable efforts to obtain permission from the third Person operator of such non-operated Property for Purchaser or the Environmental Consultant to conduct the Environmental Review; provided, however, that with respect to such non-operated Properties, Seller shall have no liability to Purchaser for failure to obtain such third Person operator’s permission (provided Seller uses such commercially reasonable efforts to obtain such permission), and Seller shall not be required to make any payments or undertake any obligations for the benefit of any other Person with respect to such access to such non-operated Properties. Seller shall have the right to have one or more representatives accompany Purchaser and the Environmental Consultant at all times during the Environmental Review. The Environmental Review and any access under Section 6.1 shall not include any sampling, boring, operation of Equipment, or other invasive activity (each, an “Invasive Activity”) without the prior written consent of Seller, which consent can be withheld in Seller’s sole discretion with respect to Properties operated by Seller, and that of any applicable third Person operator with respect to any properties not operated by Seller or any of its Affiliates; provided, however, that in the event Purchaser’s Phase I identifies a potential Environmental Defect and Purchaser reasonably concludes that it is necessary to conduct an Invasive Activity on the Property prior to the Defect Claim Deadline and Seller or such third Person operator, as applicable, fails to grant such consent within five (5) Business Days of receipt of Producer’s request to perform such Invasive Activity, then Purchaser shall have the right to exclude the affected Property from the transactions contemplated hereunder and, in such event, (i) the Unadjusted Purchase Price shall be decreased by the Allocated Value, if any, of such affected Property, (ii) such affected Properties shall be deemed to be excluded from the definition of “Assets” and from the exhibits attached hereto, (iii) such affected Property shall be deemed to constitute Excluded Assets, and (iv) Purchaser shall have no rights or obligations with respect to such Excluded Assets.

not disclose all or any portion of the Environmental Information to any third Person without the consent of Purchaser or Seller, as applicable, which consent shall not be unreasonably withheld, conditioned or delayed. If this Agreement is terminated prior to the Closing (or if the Agreement is not terminated prior to Closing, then any Environmental Information with respect to any Excluded Asset), (x) Purchaser shall deliver the Environmental Information to Seller, which Environmental Information shall become the sole property of Seller and (y) the foregoing confidentiality obligations set forth in this Section 3.4(b) shall not apply to Seller and its Affiliates and its and their respective officers, directors, employees, contractors and consultants. Each Party shall be responsible for the compliance of its Affiliates, and its and their respective officers, directors, employees, contractors, consultants (including the Environmental Consultant), and other advisors with the immediately preceding sentence. If the Closing occurs, the foregoing confidentiality obligations set forth in this Section 3.4(b) shall not apply to Purchaser and its Affiliates and its and their respective officers, directors, employees, contractors and consultants.

(c)Purchaser acknowledges that the Assets have been used for the exploration, development, and production of Hydrocarbons and that there may be petroleum, produced water, wastes, or other substances or materials located in, on, or under the Properties or associated with the Assets.

Notwithstanding anything to the contrary in this Section 3.4 or elsewhere in this Agreement, except with respect to the representations and warranties of Seller in Section 4.16, Seller makes no, and hereby disclaims any, representation or warranty, express or implied, with respect to the presence or absence of NORM, asbestos, mercury, drilling fluids and chemicals, Hazardous Substances and produced waters and Hydrocarbons in or on the Properties or Equipment.

(d)Purchaser agrees to reasonably cooperate with Seller in reviewing and commenting on any curative materials provided by Seller (or Seller’s representatives) to Purchaser with respect to potential Title Defects and Environmental Defects of which Seller is made aware of prior to Closing.

(a)Seller shall have the right, but not the obligation, to attempt, at Seller’s sole cost, risk, and expense, to cure or remove to the reasonable satisfaction of Purchaser, on or before ninety (90) days after the Closing Date (the “Cure Date”), any alleged Title Defects or Environmental Defects of which Seller has been advised by Purchaser pursuant to Section 3.6(a) or 3.6(c).

The election by Seller to attempt to cure one or more of such alleged Title Defects or Environmental Defects shall not affect the rights and obligations of the Parties under Section 3.10 with respect to dispute resolution.

As soon as reasonably practical after Seller cures a Title Defect or Environmental Defect, but in any event no later than the Cure Date, Seller shall provide Purchaser a written notice of such cure (a “Cure Notice”). In the event that any such cure efforts for Environmental Defects require Seller and its representatives to access the Assets after Closing, Purchaser shall provide Seller reasonable access during the Cure Period to the affected Assets that are operated by Purchaser (but shall have no obligation to seek or provide access for affected Assets operated by a third party) and the Parties shall enter into a commercially typical and reasonable access and indemnity agreement relating to such access that is mutually acceptable to the Parties. In performing any such on-site curative actions, Seller shall keep Purchaser reasonably apprised of the status, scope and work program therefor.

(c)Any dispute relating to whether and to what extent a Title Defect or Environmental Defect has been cured shall be deemed to be a Disputed Matter and shall be resolved as set forth in Section 3.10, except that on or after ten (10) Business Days after the date that Seller delivers to Purchaser the Cure Notice either Party may notify the other Party of its election to submit any such matter to arbitration

and thereafter the Parties shall promptly submit such matter to the Title Arbitrator or Environmental Arbitrator, as applicable; provided, however, that any prior or concurrent determination by a Title Arbitrator or Environmental Arbitrator with respect to Title Defects or Environmental Defects (or factual or legal matters relating thereto, even if determined in connection with the resolution of an otherwise unrelated dispute) which Seller has elected to attempt to cure pursuant to Section 3.7(a) shall be binding on the Parties with respect to such Title Defect or Environmental Defect (or factual or legal matters relating thereto, even if determined in connection with the resolution of an otherwise unrelated dispute).

(d)Seller shall have the right to exclude an Asset from this Agreement if Purchaser’s estimate of the Environmental Defect Amount, as set forth in a notice delivered in accordance with 3.6(c), in each case, exceeds eighty percent (80%) of the Allocated Value of the Asset affected thereby, in which case, (A) the affected Asset shall not be conveyed to Purchaser at Closing, (B) the Unadjusted Purchase Price shall be reduced at Closing by the Allocated Value of such Asset (without regard to the limitations set forth in Section 3.9(c)(iv)), (C) such Asset shall be deemed to be deleted from Exhibit A‑1 and/or Exhibit A‑2 attached hereto and added to Schedule 1.3 attached hereto and (D) such Asset shall constitute an Excluded Asset for all purposes hereunder; provided that in such event the Environmental Defect Amount for the affected Asset(s) so excluded will not count towards the deductible set forth in Section 3.9(c)(iv)(B).

(a)With respect to each Asset for which Title Defects or Environmental Defects have been reported under Section 3.6(a) or 3.6(c), such Asset shall, unless Seller exercises its right in Section 3.7(d), be assigned at Closing subject to all Title Defects and Environmental Defects, and the Purchase Price (either at Closing or post-Closing, depending on when such Title Defects and Environmental Defects are agreed upon by the Parties, exclusively and finally resolved by arbitration pursuant to Section 3.10(a) or Section 3.10(b) or cured, as applicable), shall be reduced by (i) in the case of Title Defects, an amount determined pursuant to Section 3.9(a) (the “Title Defect Amount”), and (ii) in the case of an Environmental Defect, an amount determined pursuant to Section 3.9(c) (the “Environmental Defect Amount”), in each case as provided in Sections 3.8(d), 3.8(e) and 3.8(f), as applicable.

(b)With respect to each Property affected by Title Benefits reported under Section 3.6(b), such Property shall be assigned at Closing with such Title Benefits, and any reduction to the Unadjusted Purchase Price pursuant to Section 3.8(a) (either at Closing or post-Closing, depending on when such Title Benefits are agreed upon by the Parties or exclusively and finally resolved by arbitration pursuant to Section 3.10(a), as applicable) shall be offset by an amount as determined pursuant to Section 3.9(b) (the “Title Benefit Amount”), in each case as provided in Sections 3.8(d), 3.8(e) and 3.8(f), as applicable.

(c)Seller and Purchaser shall attempt to agree upon all the existence of any Title Defects, Title Benefits or Environmental Defects reported pursuant to Sections 3.6(a), 3.6(b) and 3.6(c) above, as applicable, and any corresponding Title Defect Amounts, Title Benefit Amounts, and Environmental Defect Amounts on or before the Closing Date. If Seller and Purchaser are unable to agree by the Closing Date, then, subject to Section 3.7, the Title Defects, Title Benefits, Environmental Defects, reported pursuant to Sections 3.6(a), 3.6(b) and 3.6(c), as applicable, and any corresponding Title Defect Amounts, Title Benefit Amounts, and Environmental Defect Amounts which are then in dispute (each, a “Disputed Matter”) shall be exclusively and finally resolved by arbitration pursuant to Section 3.10(a) with respect to Disputed Matters concerning Title Defects, Title Benefits, Title Defect Amounts and/or Title Benefit Amounts, and Section 3.10(b) with respect to Disputed Matters concerning Environmental Defects and/or Environmental Defect Amounts.

(d)At Closing, the Unadjusted Purchase Price shall be adjusted (i) in accordance with Section 3.8(a) with respect to any Title Defects and Environmental Defects which (A) Seller has not elected to attempt to cure pursuant to Section 3.7(a) and (B) which are not Disputed Matters, and (ii) in accordance with Section 3.8(b) with respect to any Title Benefits which are not Disputed Matters.

(e)At Closing, an amount equal to the sum of all reasonably estimated Title Defect Amounts and Environmental Defect Amounts (as determined in good faith by Purchaser in its Title Defect and Environmental Defect claim notices) and all reasonably estimated Title Benefit Amounts (as determined, with respect to each Title Benefit, in good faith by the applicable Party providing a Title Benefit claim notice) related to (i) any Title Defects and Environmental Defects which Seller elects to attempt to cure pursuant to Section 3.7(a) or (ii) which are Disputed Matters (such aggregate amount, the “Defect Escrow Amount”), shall, after giving effect to the provisions of Sections 3.9(a)(viii), 3.9(b)(v) and 3.9(c)(iv), be deducted in the calculation of the Closing Payment, as provided in Section 8.4(a); and at the Closing, Purchaser shall deposit the Defect Escrow Amount into an escrow account (the “Defect Escrow Account”) established with JPMorgan Chase Bank (the “Defect Escrow Agent”) pursuant to an escrow agreement in form and substance reasonably satisfactory to the Parties (the “Defect Escrow Agreement”). The Defect Escrow Amount shall be held, invested and disbursed in accordance with the terms of this Article 3 and the Defect Escrow Agreement pending the curing or resolution of the applicable Title Defects and Environmental Defects. Each Party shall deliver to the Defect Escrow Agent any customary “know your customer” information as requested by the Defect Escrow Agent. The fees and expenses of the Defect Escrow Agent shall be borne one-half (1/2) by Purchaser and one-half (1/2) by Seller.

(f)After Closing, (i) the Purchase Price shall be adjusted for any Title Defects and Environmental Defects which (A) Seller elects to attempt to cure pursuant to Section 3.7(a) and actually cures or (B) which are Disputed Matters and (ii) any adjustments to the Unadjusted Purchase Price pursuant to Section 3.8(a) and Section 3.8(f)(i), if any, will be offset by any Title Benefits which are Disputed Matters as provided in this Section 3.8(f). Within ten (10) Business Days after the determination of all Disputed Matters submitted to a Title Arbitrator or Environmental Arbitrator pursuant to Section 3.10(a) and Section 3.10(b), as applicable, the Parties shall, after giving effect to the limitations provided in Section 3.9, execute joint written instructions to the Defect Escrow Agent instructing it to pay (i) to Purchaser, the sum of the Title Defect Amounts and Environmental Defect Amounts associated with (A) those Title Defects and Environmental Defects which Seller elected to attempt to cure pursuant to Section 3.7(a) which are not Disputed Matters and which are not fully cured as provided in Section 3.7 (provided, however, if curative efforts by Seller mitigated an uncured Title Defect or Environmental Defect, the Title Defect Amount or Environmental Defect Amount associated with such Title Defect or Environmental Defect shall be revised pursuant to Section 3.9(a) or Section 3.9(c), as applicable) and (B) any Disputed Matters, determined in favor of Purchaser by the applicable Title Arbitrator or Environmental Arbitrator under Section 3.10(a) or Section 3.10(b), less any offset for such sum of Title Benefits which are Disputed Matters and are determined in favor of Seller by the Title Arbitrator under Section 3.10(a) and (ii) to Seller, the remainder of the Defect Escrow Amount. The Parties shall treat for Tax purposes, any amounts paid pursuant to this Section 3.8(f) as an adjustment to the Purchase Price and any payment made pursuant to this Section 3.8(f) shall be made by wire transfer of immediately available funds to a bank account or accounts to be designated in writing by the Party receiving such payment.

(a)The Title Defect Amount resulting from a Title Defect shall be determined as follows:

(i)if Purchaser and Seller agree in writing upon the Title Defect Amount, that amount shall be the Title Defect Amount;

(ii)if the Title Defect is a lien, encumbrance, or other charge which is liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to unconditionally remove the Title Defect from Seller’s interest in the affected Property;

(iii)if the Title Defect represents a discrepancy between (A) Seller’s aggregate ownership of Net Acres for any Lease and (B) the amount of Net Acres set forth for such Lease in Exhibit A‑1, then the Title Defect Amount shall be the product of the Allocated Value of such Lease multiplied by a fraction, the numerator of which is the difference between the number of Net Acres owned by Seller in such Lease and the number of Net Acres set forth for such Lease in Exhibit A‑1 and the denominator of which is the Net Acres set forth for such Lease in Exhibit A‑1;

(iv)if the Title Defect represents a discrepancy between (A) Seller’s Net Revenue Interest for any Property and (B) the Net Revenue Interest stated in Exhibit A‑1 or Exhibit A‑2 for such Property, and for which there is not at least a proportionate increase in Seller’s Working Interest

or Net Acre ownership for such Property from that set forth in Exhibit A‑1 or Exhibit A‑2, as applicable, for such Property, as applicable, then the Title Defect Amount shall be the product of the Allocated Value of such Property multiplied by a fraction, the numerator of which is the decrease in Seller’s Net Revenue Interest and the denominator of which is Seller’s Net Revenue Interest stated on Exhibit A‑1 or Exhibit A‑2 for such Property; provided, however, that if the Title Defect does not affect the Property throughout its entire productive life, the Title Defect Amount determined under this Section 3.9(a)(iv) shall be reduced to take into account the applicable time period only;

(v)if the Title Defect represents an obligation, encumbrance, burden, or charge upon, or other defect in title to, the affected Property of a type not described in subsections (i), (ii), (iii), or (iv) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Property so affected, the portion of Seller’s interest in the Property affected by the Title Defect, the legal effect of the Title Defect, the potential discounted economic effect of the Title Defect over the productive life of the affected Property, the values placed upon the Title Defect by Purchaser and Seller, the age of the factual matters causing or constituting the alleged Title Defect, the probability that title failure will occur with respect to any Title Defect that represents only a possibility of title failure, and such other factors as are necessary to make a proper evaluation;

(vi)if a Title Defect is reasonably susceptible of being cured, the Title Defect Amount shall be no greater than the reasonable cost and expense of curing such Title Defect;

(vii)the Title Defect Amount with respect to a Title Defect shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder or for which Purchaser otherwise receives credit in the calculation of the Purchase Price; and

(viii)notwithstanding anything to the contrary in this Article 3:

(A)an individual claim for a Title Defect for which a valid claim notice is given prior to the Defect Claim Deadline shall only generate an adjustment to the Unadjusted Purchase Price under this Article 3 if the Title Defect Amount with respect thereto exceeds Fifty Thousand Dollars ($50,000); provided, however, for purposes of determining whether the Title Defect Amount of a Property that is a Lease exceeds Fifty Thousand Dollars ($50,000), the Title Defect Amounts of all Properties that are a part of such Lease will be aggregated;

(B)the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any given Property shall not exceed the Allocated Value of such Property; and

(C)there shall be no adjustment to the Purchase Price for Title Defects unless and until the aggregate of all Title Defect Amounts which would generate an adjustment to the Unadjusted Purchase Price pursuant to Section 3.9(a)(viii)(A) exceeds one and one-half percent (1.5%) of the Unadjusted Purchase Price, and then only to the extent that such aggregate amount exceeds one and one-half percent (1.5%) of the Unadjusted Purchase Price.

(b)The Title Benefit Amount resulting from a Title Benefit shall be determined as follows:

(i)if Purchaser and Seller agree in writing upon the Title Benefit Amount, that amount shall be the Title Benefit Amount;

(ii)if the Title Benefit represents a discrepancy between (A) Seller’s aggregate Net Acre ownership in any Lease and (B) the amount of Net Acres shown for such Lease in

Exhibit A‑1, then the Title Benefit Amount shall be the product of the Allocated Value of such Lease multiplied by a fraction, the numerator of which is difference between the number of Net Acres owned by Seller in such Lease and the number of Net Acres set forth for such Lease in Exhibit A‑1 and the denominator of which is the Net Acres set forth for such Lease in Exhibit A‑1;

(iii)if the Title Benefit represents a discrepancy between (A) the Net Revenue Interest for any Property and (B) the Net Revenue Interest stated with respect to such Property in Exhibit A‑1 or Exhibit A‑2, the Title Benefit Amount shall be the product of the Allocated Value of the affected Property multiplied by a fraction, the numerator of which is the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest stated in Exhibit A‑1 or Exhibit A‑2 with respect to such Property; provided, however, that if the Title Benefit does not affect a Property throughout the entire productive life of the Property, the Title Benefit Amount determined under this Section 3.9(b)(iii) shall be reduced to take into account the applicable time period only;

(iv)if a Title Benefit represents a right, circumstance, or condition of a type not described in subsections (i), (ii) or (iii) above, the Title Benefit Amount shall be determined by taking into account the Allocated Value of the Property so affected (or in the event the Title Benefit is of the type discussed in clause (iv) of the definition of thereof, the Allocated Value of the Properties nearest by of the same or similar type and covering the same Target Formation(s)), the portion of Seller’s interest in the Property so affected, the legal effect of the Title Benefit, the potential discounted economic effect of the Title Benefit over the productive life of any affected Property, the values placed upon the Title Benefit by Purchaser and Seller, and such other factors as are necessary to make a proper evaluation; and

(v)notwithstanding anything to the contrary in this Article 3:

(A)an individual claim for a Title Benefit for which a valid claim notice is given prior to the Defect Claim Deadline shall only be taken into account under this Article 3 to offset Title Defect Amounts if the Title Benefit Amount with respect thereto exceeds Fifty Thousand Dollars ($50,000); provided, however, for purposes of determining whether the Title Benefit Amount of a Property that is a Lease exceeds Fifty Thousand Dollars ($50,000), the Title Benefit Amounts of all Properties that are a part of such Lease will be aggregated; and

(B)in no event shall the Purchase Price be increased in respect of any Title Benefit or Title Benefit Amount; rather the amount of all individual Title Benefits that individually exceed the threshold described in clause (v) above shall offset any downward adjustment to the Purchase Price to which Purchaser would otherwise be entitled pursuant to this Agreement in respect of Title Defects.

(c)The Environmental Defect Amount resulting from an Environmental Defect shall be determined as follows:

(i)if Purchaser and Seller agree on the Environmental Defect Amount, that amount shall be the Environmental Defect Amount;

(ii)the Environmental Defect Amount shall include but shall not exceed the reasonable cost of the response required under Environmental Laws that addresses the applicable Environmental Defect with the most cost-effective Remediation of such Environmental Defect (considered as a whole, taking into consideration any material impacts such response may have on the continued, safe and prudent operation of the Affected Asset);

(iii)the Environmental Defect Amount with respect to an Environmental Defect shall be determined without duplication of any costs or losses included in another Environmental Defect Amount or adjustment to the Purchase Price hereunder; and

(iv)notwithstanding anything to the contrary in this Article 3:

(A)an individual claim for an Environmental Defect for which a valid claim notice is given prior to the Defect Claim Deadline shall only generate an adjustment to the Unadjusted Purchase Price if the Environmental Defect Amount with respect thereto exceeds One Hundred Thousand Dollars ($100,000);

(B)there shall be no adjustment to the Unadjusted Purchase Price for Environmental Defects unless and until the aggregate of all Environmental Defect Amounts which would generate an adjustment to the Unadjusted Purchase Price pursuant to Section 3.9(c)(iv)(A) exceeds one and one-half percent (1.5 %) of the Unadjusted Purchase Price, and then only to the extent that such aggregate amount exceeds one and one-half percent (1.5 %) of the Unadjusted Purchase Price.

(a)Except as provided in Section 3.7(c), with respect to any Disputed Matter concerning Title Defects, Title Benefits, Title Defect Amounts and/or Title Benefit Amounts (“Disputed Title Matters”), on or after a date that is ten (10) Business Days following the Closing Date, either Party may notify the other Party of its election to submit all remaining Disputed Title Matters to a title attorney with at least ten (10) years’ experience in oil and gas titles in the State of Texas, as selected by mutual agreement of Purchaser and Seller (the “Title Arbitrator”) and thereafter the Parties shall promptly submit such remaining Disputed Title Matters to the Title Arbitrator. If Purchaser and Seller have not agreed upon a Person to serve as Title Arbitrator within ten (10) Business Days of a Party’s election to submit such Disputed Title Matters to the Title Arbitrator, the Parties shall, within five (5) Business Days after the end of such ten (10) Business Day period, formally apply to the Houston, Texas office of the American Arbitration Association (or in the event that there is no such office in Houston, Texas at such time, to any other office of the American Arbitration Association) to choose the Title Arbitrator and submit such Disputed Title Matters along with such application. The Title Arbitrator shall not have worked as an employee or outside counsel for any Party orits Affiliates during the ten (10) year period preceding the arbitration or have any financial interest in the dispute other than the payment of the Title Arbitrator’s fees and expenses incurred as Title Arbitrator.

(b)Except as provided in Section 3.7(c), with respect to any Disputed Matter concerning Environmental Defects and Environmental Defect Amounts (“Disputed Environmental Matters”), on or after a date that is ten (10) Business Days following the Closing Date, either Party may notify the other Party of its election to submit all remaining Disputed Environmental Matters to a reputable environmental consultant with at least ten (10) years’ experience in corrective environmental action regarding oil and gas properties in the State of Texas, as selected by mutual agreement of Purchaser and Seller (the “Environmental Arbitrator”) and thereafter the Parties shall promptly submit such remaining Disputed Environmental Matters to the Environmental Arbitrator. If Purchaser and Seller have not agreed upon a Person to serve as Environmental Arbitrator within ten (10) Business Days of a Party’s election to submit such Disputed Environmental Matters to the Environmental Arbitrator, the Parties shall, within five (5) Business Days after the end of such ten (10) Business Day period, formally apply to the Houston, Texas office of the American Arbitration Association (or in the event that there is no such office in Houston, Texas at such time, to any other office of the American Arbitration Association) to choose the Environmental Arbitrator and submit such Disputed Environmental Matters along with such application. The Environmental Arbitrator shall not have worked as an employee or outside consultant for any Party or

its Affiliates during the ten (10) year period preceding the arbitration or have any financial interest in the dispute other than the payment of the Environmental Arbitrator’s fees and expenses incurred as Environmental Arbitrator.

(c)In each case above, 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 3.10. The Title Arbitrator’s or Environmental Arbitrator’s determination, as applicable, shall be made within forty-five (45) days after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal. In making their respective determinations, the Title Arbitrator and the Environmental Arbitrator shall be bound by the provisions of this Article 3 and may consider such other matters as, in the opinion of the Title Arbitrator or Environmental Arbitrator (as applicable), are necessary or helpful to make a proper determination. The Title Arbitrator and Environmental Arbitrator may consult with and engage disinterested third Persons to advise the arbitrator, including petroleum engineers. The Title Arbitrator and Environmental Arbitrator shall act as experts for the limited purpose of determining the specific Disputed Matters submitted by any Party, may only award Seller’s position or Purchaser’s position with respect to Title Defect Amounts, Title Benefit Amounts and Environmental Defect Amounts (or a position in between Seller’s position and Purchaser’s position) and may not award damages, interest, fees or penalties to any Party with respect to any matter. Seller and Purchaser shall each bear their own legal fees and other costs of presenting their respective cases to any Title Arbitrator or Environmental Arbitrator pursuant to this Section 3.10. The fees and expenses of the Title Arbitrator and Environmental Arbitrator shall be paid by Seller, on the one hand, and by Purchaser, on the other hand, based upon the proportion as determined by such Title Arbitrator or Environmental Arbitrator, in each case, that the amount actually contested but not awarded to Seller or Purchaser, respectively, bears to the aggregate amount actually contested by Seller and Purchaser.

3.11    Notice to Holders of Consent and Preferential Purchase Rights. No later than ten (10) Business Days after the date hereof, Seller shall prepare and send (a) notices to the holders of any consents to the assignment of the Assets that may be triggered by the transactions contemplated by this Agreement (including to the holders of Material Consents that are set forth on Schedule 4.9(b) but excluding any consent or approval of Governmental Authorities customarily obtained after Closing) requesting consents to the transactions contemplated by this Agreement and (b) notices to the holders of any applicable preferential rights to purchase or similar rights requesting waivers of such rights, including those that are set forth on Schedule 4.9(a), in each case, in compliance with the terms of such rights. Seller shall use commercially reasonable efforts to cause any such consent to assignment of the Assets and such preferential right to purchase to be obtained and delivered or waived, as applicable, prior to Closing; provided, that except as provided in the following sentence, Seller shall not be required to make any payments or undertake any material obligations for the benefit of the holders of such rights in order to obtain the consents and waivers. Seller shall be obligated to pay any amount in accordance with the current University of Texas System/University Lands Rate and Damage Schedule to the extent necessary to obtain consents to assignment for an Asset. Purchaser shall use commercially reasonable efforts to cooperate with Seller in seeking to obtain such consents, approvals, permissions, and waivers; provided, that Purchaser shall not be required to make any payments or undertake any obligations or liabilities in order to obtain such consents, approvals, permissions and waivers.

(a)Unless the Parties otherwise agree in writing, in no event shall there be transferred at Closing any Asset (other than a Right of Way) for which a Material Consent has not been obtained prior to Closing.

(b)In cases in which the Asset subject to such an un-obtained Material Consent is an Asset other than a Property, and Purchaser is assigned the Property or Properties to which such Asset relates, but such Asset is not transferred to Purchaser due to the un-waived Material Consent requirement, until the date of the final adjustment to the Unadjusted Purchase Price under Sections 8.4(b) or 8.4(c) (the “Final Adjustment Date”), the Parties shall continue to use commercially reasonable efforts to obtain the Material Consent so that such Asset can be transferred to Purchaser upon receipt of the Material Consent, and, if permitted pursuant to applicable Law and agreement, such Asset shall be held by Seller for the benefit of Purchaser, Purchaser shall pay all amounts due thereunder or with respect thereto, and Purchaser shall be responsible for the performance of any obligations under or with respect to such Asset to the extent that Purchaser has been transferred the Assets necessary to such performance until the applicable Material Consent is obtained. Notwithstanding the foregoing, except for payments by Seller in accordance with the current University of Texas System/University Lands Rate and Damage Schedule, neither Party shall be required to make any payments or undertake any material obligations for the benefit of the holders of any un‑obtained Material Consents subject to this Section 3.12(b). With respect to the Assets for which the un‑obtained Material Consent is not obtained by or before the Final Adjustment Date, Seller shall promptly reimburse Purchaser for the costs and expenses paid by Purchaser associated with such Assets and Purchaser shall promptly reimburse Seller for the revenues associated with such Assets.

(c)In cases in which the Asset subject to such a Material Consent requirement is a Property and the Material Consent to the transfer of such Property is not obtained by Closing, either Party may elect to exclude the Property subject to such Material Consent and, subject to the remainder of this Section 3.12(c), (i) the affected Property shall not be conveyed to Purchaser at Closing, (ii) the Unadjusted Purchase Price shall be reduced at Closing by the Allocated Value of such Property, (iii) such Property shall be deemed to be deleted from Exhibit A‑1 and/or Exhibit A‑2 attached hereto and added to Schedule 1.3 attached hereto and (iv) such Property shall constitute an Excluded Asset for all purposes hereunder. If any such Material Consent requirement with respect to which an adjustment to the Unadjusted Purchase Price is made under Section 2.3(b) is subsequently satisfied prior to the date of the final adjustment to the Unadjusted Purchase Price under Section 8.4(b) or Section 8.4(c), (A) Seller shall, promptly after such Material Consent requirement is satisfied, convey the applicable Property to Purchaser; (B) the Parties shall deliver all instruments and documents that would have been required under the terms hereof to be delivered at Closing with respect to such Properties at Closing; (C) Purchaser shall, simultaneously with the conveyance of the applicable Property, pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Property (or portion thereof) under this Agreement); and (D) such Property shall no longer be deemed to be (x) deleted from Exhibit A‑1 and/or Exhibit A‑2, (y) added to Schedule 1.3 attached hereto and (z) an Excluded Asset for any purposes hereunder. Notwithstanding the forgoing, in cases in which the Asset subject to such a Material Consent requirement is a Right of Way, such Right of Way shall nevertheless be assigned by Seller to Purchaser at Closing as part of the Assets, without adjustment to the Purchase Price in respect of such un-obtained consent, and Purchaser shall have no claim against, and Seller shall have no liability for, the failure to obtain such consent (provided that the forgoing shall not limit Purchaser’s remedies under this Agreement with respect to a breach by Seller of its covenants in Section 3.11).

(d)If Seller fails to obtain a consent prior to Closing and such consent is not a Material Consent, then the Asset (or the portion thereof) subject to such un-obtained consent shall nevertheless be assigned by Seller to Purchaser at Closing as part of the Assets, without adjustment to the Purchase Price in respect of such un-obtained consent, and Purchaser shall have no claim against, and Seller shall have no liability for, the failure to obtain such consent (provided that the forgoing shall not limit Purchaser’s remedies under this Agreement with respect to a breach by Seller of its covenants in Section 3.11).

(a)Any preferential purchase right must be exercised subject to all terms and conditions set forth in this Agreement, including the successful Closing of this Agreement pursuant to Section 8.1 on the dates set forth herein. The consideration payable under this Agreement for any particular Asset for purposes of preferential purchase right notices shall be the Allocated Value for such Asset, adjusted as set forth herein.

(b)If any preferential right to purchase any Asset is validly exercised prior to Closing, (i) the affected Asset shall not be conveyed to Purchaser at Closing, (ii) the Unadjusted Purchase Price shall be reduced by the Allocated Value of such Asset, (iii) such Asset shall be deemed to be deleted from the Exhibits attached hereto and added to Schedule 1.3 attached hereto, (iv) such Asset shall constitute an Excluded Asset for all purposes hereunder, and (v) Seller shall convey the affected Asset to the preferential right holder on the terms and provisions set out in the applicable preferential right provision and shall be entitled to the consideration paid by such holder.

(c)Should a third Person fail to validly exercise or waive its preferential right to purchase as to any portion of the Assets prior to Closing, and the time for exercise or waiver has not yet expired by Closing, then (i) such Assets (or portions thereof) shall not be conveyed to Purchaser at Closing, (ii) the Unadjusted Purchase Price shall be reduced by the Allocated Value of each such Asset (or portion thereof); (iii) each such affected Asset (or portion thereof) shall be subject to the remainder of this Section 3.13(c) and Section 3.13(d), and (iv) Seller shall continue to use commercially reasonable efforts (without the obligation to make any payments or undertake any obligations for the benefit of the holders of such preferential rights to purchase) to obtain the waiver of the preferential purchase right and shall continue to be responsible for the compliance therewith. Should the holder of the preferential purchase right validly exercise the same after Closing, (A) such affected Asset shall be deemed to be deleted from the Exhibits attached hereto and added to Schedule 1.3 attached hereto, (B) such Asset (or portion thereof) shall constitute an Excluded Asset for all purposes hereunder, and (C) Seller shall convey the affected Asset (or portion thereof) to the preferential right holder on the terms and provisions set out in the applicable preferential right provision and Seller shall be entitled to the consideration paid by such holder.

(d)In the event that, after Closing, a preferential purchase right with respect to an Asset (or portion thereof) not conveyed to Purchaser at Closing pursuant to Section 3.13(c) is waived or the time for exercise of such right has expired pursuant to its terms without exercise in writing by the holder thereof, (i) Purchaser shall purchase the affected Asset (or portion thereof) on the terms set forth in this Agreement at a delayed closing which shall occur within ten (10) Business Days following the date on which Seller obtains such waiver, or the time period for exercising the applicable preferential right has expired (which date shall, with respect to such Asset, or portion thereof, be considered to be the Closing Date), (ii) the Parties shall deliver all instruments and documents that would have been required under the terms hereof to be delivered at Closing with respect to such Asset at such delayed Closing; and (iii) Purchaser shall, simultaneously with the conveyance of the applicable Asset (or portion thereof), pay the amount of any previous deduction from the Unadjusted Purchase Price (subject to all other applicable adjustments with respect to such Property under this Agreement) to Seller and (iv) such Asset shall no longer be (A) deemed to be deleted from the Exhibits attached hereto, (B) added to Schedule 1.3 attached hereto and (C) an Excluded Asset for any purposes hereunder. Purchase Price adjustments calculated in the same manner as the adjustments in Section 2.3 with respect to the affected Asset (or portion thereof), if any, shall be calculated from the period from and after the Effective Time to the date of the conveyance, and the net amount of such adjustment, if positive, shall be paid by Purchaser to Seller, and, if negative, by Seller to Purchaser at the delayed Closing.

Such cooperation will include (i) reasonable access to Seller’s officers, managers, employees, agents and representatives who were responsible for preparing or maintaining the financial records and work papers and other supporting documents used in the preparation of such financial statements as may be reasonably required by Purchaser’s Auditor to perform an audit or conduct a review in accordance with generally accepted auditing standards or to otherwise verify such financial statements, (ii) delivery of one or more customary representation letters from Seller to Purchaser’s Auditor that are reasonably requested by Purchaser to allow such auditors to complete an audit (or review of any financial statements), and to issue an opinion acceptable to Purchaser’s Auditor with respect to an audit or review of those financial records required pursuant to this Section 6.14(b) and (iii) using reasonable efforts to obtain the consent of the independent auditor of Seller that conducted any audit of such financial statements to be named as an expert in any report filed by Purchaser with the U.S. Securities and Exchange Commission.

Notwithstanding the foregoing, nothing herein shall expand Seller’s representations, warranties, covenants, or agreements set forth in this Agreement or give Purchaser, its Affiliates, or any third Person any rights to which it is not entitled hereunder.

(c)For a period of three (3) years following the Closing Date, Seller shall, and shall cause its respective Affiliates to, retain all books, records, information and documents in its or their possession that are reasonably necessary to prepare and audit financial statements with respect to the Assets, except to the extent originals or copies thereof are transferred to Purchaser in connection with Closing. Purchaser shall indemnify and hold harmless Seller Group from and against any and all Damages suffered or incurred by them arising from any claims by third Persons or Governmental Authorities against them in connection with any action taken by them at the request of Purchaser pursuant to Section 6.14 or in connection with the arrangement of any financings or securities offerings and any filing made pursuant to applicable securities Laws or other disclosures in connection with any such financings or securities offerings, except to the extent such Damages arise as a result of the gross negligence or intentional misconduct of any member of the Seller Group.

Seller shall make available for interview by Purchaser or its Affiliates, at Purchaser’s request, the Available Employees within five (5) days after the Execution Date.  In the event that Purchaser chooses to interview an Available Employee prior to the Closing (an “Interview”), Purchaser shall have the right, but not the obligation, at the sooner of (i) fourteen (14) Business Days after the Interview or (ii) ten (10) days prior to Closing, to make a written offer of employment or consultancy (as an employee, contractor or consultant) to an Available Employee that is conditioned on the occurrence of the Closing, as further described in Section 6.16(b). Any such offer of employment shall include employment terms that credit employment

service with Seller and its Affiliates under the employee benefit plans maintained by Purchaser or its Affiliate for purposes of eligibility and vesting (but not for benefit accruals). No such offer of employment or consultancy shall be for employment or consultancy that begins prior to the Closing.

(b)To the extent that Purchaser intends to make any offer to any of the Available Employees, Purchaser shall provide written notice of the offer (and the terms and conditions thereof, including the proposed term, compensation and benefits offered) to Seller.  If, within one (1) year after Closing, Purchaser intends to make any offer of employment or consultancy (as employee, contractor or consultant) to any Available Employee that did not become an employee or consultant to the Purchaser at the Closing, Purchaser will provide Seller with written notice at least five (5) Business Days prior to making any such offer (and the terms and conditions thereof, including the proposed term, compensation and benefits offered).

(c)Seller and Purchaser acknowledge and agree that all provisions contained in Section 6.16 are included for the sole benefit of Seller and Purchaser and that nothing contained herein, express or implied, is intended to (i) confer upon any Person (including any Available Employee) any right to an offer of employment or continued employment for any period or continued receipt of any specific employee benefit, (ii) constitute an amendment to or any other modification of any employee benefit plan, program or agreement of any kind or (iii) create any third party beneficiary or other rights in any other Person, any participant in any benefit plan or any dependent or beneficiary thereof.  Nothing in this Agreement shall be interpreted as limiting the power of Seller or Purchaser or any of their Affiliates to amend or terminate any particular employee benefit plan, program, agreement or policy or to amend the terms of employment or compensation of any Transferring Employee or to terminate the employment of any Transferring Employee at any time and for any reason.

(c)From and after the Closing Date, Seller shall promptly notify Purchaser of any resolution or release of Seller Responsibility Suspense Amounts that relates to Purchaser Responsibility Suspense Amounts and shall provide Purchaser such information reasonably requested by Purchaser relating to such resolution or release so that Purchaser can resolve or release its related Purchaser Responsibility Suspense Amounts.

8.4    Closing Payment and Post-Closing Purchase Price Adjustments.

(a)Not later than five (5) Business Days prior to the Closing Date, Seller shall prepare and deliver to Purchaser, using and based upon information reasonably available to Seller, a preliminary settlement statement setting forth (i) Seller’s good faith estimate of the Purchase Price for the Assets after giving effect to all adjustments set forth in Section 2.3 and (ii) wiring instructions for the Closing Payment. Seller shall supply to Purchaser reasonable documentation in the possession of Seller or its Affiliates reasonably necessary to support the items for which adjustments are proposed or made in the preliminary settlement statement delivered by Seller, and a brief explanation of any such adjustments and the reasons therefor. For a period of two (2) Business Days after receipt from Seller of its preliminary settlement statement, Purchaser will have the right, but not the obligation to review and discuss the preliminary settlement statement and deliver to Seller a written report containing any proposed changes to the preliminary settlement statement, if any, together with a brief explanation of such changes. The preliminary settlement statement, as agreed by the Parties, will be used to adjust the Purchase Price at Closing, provided, however, that if the Parties cannot agree on all adjustments set forth in the preliminary settlement statement prior to the Closing, then any such unagreed adjustments as set forth in the preliminary settlement statement presented by Seller will be used to adjust the Purchase Price at Closing provided, further, that amounts in the preliminary settlement statement with respect to Title Defect Amounts, Environmental Defect Amounts and Title Benefit Amounts shall be determined in accordance with Article 3. The estimate determined in accordance with this Section 8.4(a), less the Deposit and the Defect Escrow Amount as determined pursuant to Section 3.8(e) (if any), shall constitute the dollar amount to be payable by Purchaser to Seller at the Closing (the “Closing Payment”).

(b)As soon as reasonably practicable after the Closing but not later than the ninetieth (90th) day following the Closing Date, Seller shall prepare and deliver to Purchaser a draft statement setting forth the final calculation of the Purchase Price and showing the calculation of each adjustment under Section 2.3, based on the most recent actual figures available for each adjustment. Seller shall supply to Purchaser reasonable documentation in the possession of Seller or its Affiliates reasonably necessary to support the items for which adjustments are proposed or made in the settlement statement delivered by Seller, and a brief explanation of any such adjustments and the reasons therefor. As soon as reasonably practicable, but not later than the thirtieth (30th) day following receipt of such statement from Seller, Purchaser may deliver to Seller a written report containing any changes that Purchaser proposes be made to such statement, which shall include reasonable documentation in the possession of Purchaser or its Affiliates reasonably necessary to support the proposed changes. Seller may deliver a written report to Purchaser during this same period reflecting any changes that Seller proposes to be made to such statement as a result of additional information received after the statement was prepared. If Purchaser does not deliver

such report to Seller on or before the end of such thirty (30) day period, Purchaser shall be deemed to have agreed with Seller’s statement, and such statement shall become final and binding upon the Parties, without limiting payments made pursuant to Sections 9.1(c) or Purchaser’s right to indemnity under Section 11.2(b)(i) with respect to clause (c) of the definition of Retained Obligations.

(c)The Parties shall undertake to agree on the final statement of the Purchase Price no later than forty-five (45) days after delivery of Seller’s statement. In the event that the Parties cannot reach agreement within such period of time, either Party may propose to the other Party that the Parties refer the items of adjustment which are in dispute to the Houston, Texas office of a nationally-recognized independent accounting firm or consulting firm mutually acceptable to both Purchaser and Seller (the “Accounting Arbitrator”), for review and final determination by arbitration and thereafter the Parties shall promptly submit such items of adjustment which are in dispute to the Accounting Arbitrator. If Purchaser and Seller have not agreed upon a mutually acceptable Person to serve as the Accounting Arbitrator within ten (10) Business Days of a Party proposing that the disputed items of adjustment be referred to the Accounting Arbitrator, the Parties shall, within ten (10) Business Days after the end of such initial ten (10) Business Day period, formally apply to the Houston, Texas office of the American Arbitration Association (or in the event that there is no such office in Houston, Texas at such time, to any other office of the American Arbitration Association) to choose the Accounting Arbitrator. The Accounting Arbitrator shall conduct the arbitration proceedings in Houston, Texas 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 8.4(c). The Accounting Arbitrator’s determination shall be made within forty-five (45) days after submission of the matters in dispute and shall be final and binding on all Parties, without right of appeal, without limiting payments made pursuant to Sections 9.1(c) or Purchaser’s right to indemnity under Section 11.2(b)(i) with respect to clause (c) of the definition of Retained Obligations. In determining the proper amount of any adjustment to the Purchase Price, the Accounting Arbitrator shall be bound by the terms of Article 2 and may not increase the Purchase Price more than the increase proposed by Seller nor decrease the Purchase Price more than the decrease proposed by Purchaser, as applicable. The Accounting Arbitrator shall act as an expert for the limited purpose of determining the specific disputed aspects of Purchase Price adjustments submitted by any Party and may not award damages, interest (except as expressly provided for in this Section 8.4(c)) or penalties to any Party with respect to any matter. Seller and Purchaser shall each bear their own legal and accounting fees and other costs of presenting its case to the Accounting Arbitrator. Seller shall bear one‑half and Purchaser shall bear one‑half of the costs and expenses of the Accounting Arbitrator. Within ten (10) days after the earlier of (i) the expiration of Purchaser’s thirty (30) day review period without delivery of any written report or (ii) the date on which the Parties or the Accounting Arbitrator finally determine the Purchase Price, (x) Purchaser shall pay to Seller the amount by which the Purchase Price (less the Deposit and the Defect Escrow Amount) exceeds the Closing Payment or (y) Seller shall pay to Purchaser the amount by which the Closing Payment exceeds the Purchase Price (less the Deposit and the Defect Escrow Amount), as applicable.

(d)Purchaser shall use reasonable efforts to assist Seller in preparation of the final statement of the Purchase Price under Section 8.4(b) by furnishing invoices, receipts, reasonable access to personnel, and such other assistance as may be reasonably requested by Seller to facilitate such process post-Closing.

(e)All payments made or to be made under this Agreement to a Party shall be made by electronic transfer of immediately available funds to a bank account as may be specified by such Party in writing.

9.1    Allocation of Asset Taxes.

(a)Seller shall be allocated and bear all Asset Taxes attributable to (i) any Tax period ending prior to the Effective Time and (ii) the portion of any Straddle Period ending immediately prior to the Effective Time. Purchaser shall bear and be allocated all Asset Taxes attributable to (A) any Tax period beginning on or after the Effective Time and (B) the portion of any Straddle Period beginning at the Effective Time.

(b)For purposes of determining the allocations described in Section 9.1(a), (i) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than such Asset Taxes described in clause (iii), below) shall be allocated to the period in which the severance or production giving rise to such Asset Taxes occurred; provided that, if Purchaser becomes entitled, pursuant to Section 2.4(a), to any amounts earned from the sale of Hydrocarbons prior to the Effective Time, which amounts are received after the Cut-Off Date, Purchaser shall be allocated all Asset Taxes attributable to the production of such Hydrocarbons or the receipt of proceeds therefrom notwithstanding that such Hydrocarbons were produced prior to the Effective Time, (ii) Asset Taxes that are based upon or related to sales or receipts or imposed on a transactional basis (other than such Asset Taxes described in clause (i) or (iii)), shall be allocated to the period in which the transaction giving rise to such Asset Taxes occurred, and (iii) Asset Taxes that are ad valorem, property or other Asset Taxes imposed on a periodic basis pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending immediately prior to the Effective Time and the portion of such Straddle Period beginning at the Effective Time by prorating each such Asset Tax based on the number of days in the applicable Straddle Period that occur before the date on which the Effective Time occurs, on the one hand, and the number of days in such Straddle Period that occur on or after the date on which the Effective Time occurs, on the other hand. 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.

(i)Subject to Section 9.1(c)(ii), Purchaser shall pay (or cause to be paid) prior to delinquency, all Asset Taxes that become due after the Closing Date. With respect to any such Asset Taxes that are attributable to any Tax period beginning before the Effective Time, Purchaser shall send to Seller a statement that allocates each such Asset Tax pursuant to Section 9.1 based upon the amount of such Asset Tax actually invoiced and paid to the applicable Governmental Authority by Purchaser. Such statement shall be accompanied by proof of Purchaser’s actual payment of each such Asset Tax. Within ten (10) Business Days of receipt of each such statement and proof of payment, Seller shall reimburse Purchaser for Seller’s allocated portion of each such Asset Tax, less any amounts reflected as a reduction in the Purchase Price attributable to such Asset Tax pursuant to Section 2.3(g)(ii) (as reflected on the settlement statement as finally determined pursuant to Section 8.4(b) or Section 8.4(c), as applicable).

(ii)Notwithstanding Section 9.1(c)(i), Seller shall be responsible for paying (or causing to be paid) prior to delinquency (i) any severance Asset Taxes through the production month in which the Closing occurs and (ii) sales or use Asset Taxes attributable to any Tax period (or portion thereof) ending on or prior to the Closing Date, in each case, that become due after the Closing Date, and the

preparation and timely filing of any Tax Return relating to such Asset Taxes. Seller shall provide Purchaser with copies of any such Tax Returns and proof of payment of such Asset Taxes.

(iii)The Parties agree that (A) this Section 9.1(c) is intended to solely address the timing and manner in which certain Tax Returns relating to Asset Taxes are filed and the Asset Taxes shown thereon are paid to the applicable taxing authority, and (B) nothing in this Section 9.1(c) shall be interpreted as altering the manner in which Asset Taxes are allocated to and economically borne by the Parties (except for any penalties, interest or additions to Tax imposed as a result of any breach by a Party of its obligations under this Section 9.1(c), which shall be borne by such Party).

9.2    Transfer Taxes. To the extent that any sales, purchase, transfer, stamp, documentary stamp, registration, use or similar Taxes are payable by reason of the sale of the Assets under this Agreement (“Transfer Taxes”), such Transfer Taxes shall be borne and timely paid one-half by Purchaser and one-half by Seller. Purchaser and Seller shall reasonably cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Transfer Taxes.

9.3    Cooperation on Tax Matters. The Parties shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation, or other proceeding with respect to Taxes relating to the Assets. Such cooperation shall include the retention and (upon another Party’s request) the provision of records and information that are relevant to any such Tax Return or audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided under this Agreement. Seller and Purchaser agree to retain all books and records with respect to Tax matters pertinent to the Assets relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the respective taxable periods and to abide by all record retention agreements entered into with any Governmental Authority.

9.4    1031 Like-Kind Exchange Cooperation. Seller and Purchaser agree that either or both of Seller and Purchaser may elect to treat the acquisition or sale of all or a portion of the Assets as an exchange of like-kind property under Section 1031 of the Code (an “Exchange”), provided that Closing shall not be delayed by reason of the Exchange. Each Party agrees to use reasonable efforts to cooperate with the other Party in the completion of such an Exchange including an Exchange subject to the procedures outlined in Treasury Regulation Section 1.1031(k)-1 and/or Internal Revenue Service Revenue Procedure 2000-37. Each of Seller and Purchaser shall have the right at any time prior to Closing to assign all or a portion of its rights under this Agreement to a qualified intermediary (as that term is defined in Treasury Regulation Section 1.1031(k)-1(g)(4)(v)) or an exchange accommodation titleholder (as that term is defined in Internal Revenue Service Revenue Procedure 2000-37) to effect an Exchange. In connection with any such Exchange, any exchange accommodation title holder shall have taken all steps necessary to own the Assets (or the applicable portion of the Assets) under applicable Law. Each Party acknowledges and agrees that neither an assignment of a Party’s rights under this Agreement for purposes of an Exchange nor any other actions taken by a Party or any other person in connection with the Exchange shall release any Party from, or modify, any of their respective liabilities and obligations (including indemnity obligations to each other) under this Agreement, and no Party makes any representations as to any particular Tax treatment that may be afforded to any other Party by reason of such assignment or any other actions taken in connection with the Exchange. Any Party electing to treat the acquisition or sale of all or a portion of the Assets as an Exchange shall be obligated to pay all additional costs incurred hereunder as a result of the Exchange, and in consideration for the cooperation of the other Party, the Party electing Exchange treatment shall agree to pay all costs associated with the Exchange and to indemnify and hold the other Party, its Affiliates, and its and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives harmless from and against any and all Damages and Taxes arising out of, based upon, attributable to or resulting from the Exchange or transactions or actions taken in

connection with the Exchange that would not have been incurred by the other Party but for the electing Party’s Exchange election.

9.5    Allocation of Purchase Price. Purchaser and Seller shall use commercially reasonable efforts to agree to an allocation of the Purchase Price and any other items properly treated as consideration for U.S. federal income Tax purposes among the Assets in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder and, to the extent allowed under applicable federal income tax Law, in a manner consistent with the Allocated Values, within thirty (30) days after the date that the final statement of the Purchase Price is finally determined pursuant to Section 8.4 (the “Allocation”).  If Seller and Buyer reach an agreement with respect to the Allocation, (i) Purchaser and Seller shall use commercially reasonable efforts to update the Allocation in accordance with Section 1060 of the Code following any adjustment to the Purchase Price pursuant to this Agreement, and (ii) Purchaser and Seller shall, and shall cause their Affiliates to, report consistently with the Allocation, as adjusted, on all Tax Returns, including Internal Revenue Service Form 8594 (Asset Acquisition Statement under Section 1060), which Purchaser and Seller shall timely file with the IRS, and neither Seller nor Purchaser shall take any position on any Tax Return that is inconsistent with the Allocation, as adjusted, unless otherwise required by applicable Law; provided, however, that neither Party shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any Tax audit, claim or similar proceedings in connection with such allocation.

9.6    Tax Proceedings. After the Closing:

(a)Purchaser shall promptly provide Seller with written notice of any inquiries, audits, examinations or proposed adjustments by any Governmental Authority or any other Claim relating to Asset Taxes (“Tax Proceeding”), which relates to any Asset Taxes for any Tax period ending prior to the Effective Time other than a Straddle Period; provided that the failure of Purchaser to give notice of a Tax Proceeding as provided in this Section 9.6(a) shall not relieve Seller of its obligations under Section 6.5, Section 9.4 or Article 11, except to the extent such failure results in insufficient time being available to permit Seller to effectively defend against the Tax Proceeding or otherwise materially prejudices the Seller’s ability to defend against the Tax Proceeding. Seller shall have the sole right to defend any such Tax Proceeding relating to any Tax period ending prior to the Effective Time, but not a Straddle Period, provided that Purchaser shall have the right to participate in any such Tax Proceeding and Seller shall not settle any such Tax Proceeding without the written consent of Purchaser (which consent shall not be unreasonably withheld, conditioned or delayed).

(b)The Parties shall promptly provide each other with notice of any Tax Proceeding that relates to any Asset Taxes for any Straddle Period. Purchaser and Seller shall jointly control the conduct of any Tax Proceeding relating to Asset Taxes for a Straddle Period, and neither Purchaser nor Seller shall settle any such Tax Proceeding without the written consent of the other Person (which consent shall not be unreasonably withheld, conditioned or delayed).

(c)Seller shall promptly provide Purchaser with written notice of any Tax Proceeding, which relates to any Asset Taxes for any Tax period beginning on or after the Effective Time other than a Straddle Period. Except as provided in Section 9.6(a) and Section 9.6(b), Purchaser shall have the right to control all other Tax Proceedings with respect to Asset Taxes.

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

(a)by the mutual prior written consent of Seller and Purchaser;

(b)by either Seller or Purchaser if the Closing has not occurred on or before June 28, 2019;

(c)by Seller, at Seller’s option, if any of the conditions set forth in Section 7.1 (other than Sections 7.1(c) or 7.1(d)) have not been satisfied by the Target Closing Date (except for those conditions that by their nature are to be satisfied at the Closing and that would have been capable of being satisfied at the Closing) and, following written notice thereof from Seller to Purchaser specifying the reason such condition is unsatisfied (including any breach by Purchaser of this Agreement), such condition remains unsatisfied for a period of fifteen (15) days after Purchaser’s receipt of written notice thereof from Seller; or

(d)by Purchaser, at Purchaser’s option, if any of the conditions set forth in Section 7.2 (other than Sections 7.2(c) or 7.2(d)) have not been satisfied by the Target Closing Date (except for those conditions that by their nature are to be satisfied at the Closing and that would have been capable of being satisfied at the Closing) and, following written notice thereof from Purchaser to Seller specifying the reason such condition is unsatisfied (including any breach by Seller of this Agreement), such condition remains unsatisfied for a period of fifteen (15) days after Seller’s receipt of written notice thereof from Purchaser; or

(e)by either Seller or Purchaser if consummation of the transactions contemplated hereby is enjoined, restrained or otherwise prohibited or otherwise made illegal by the terms of a final, non-appealable order;

provided, however, that Purchaser shall not be entitled to terminate this Agreement pursuant to Sections 10.1(b) or 10.1(d) above if Purchaser is, at such time, in material breach of this Agreement, and provided further that Seller shall not be entitled to terminate this Agreement pursuant to Sections 10.1(b) or 10.1(c) above if Seller is, at such time, in material breach of this Agreement.

10.2    Effect of Termination. If this Agreement is terminated pursuant to Section 10.1, subject to the remainder of this Section 10.2 and Section 10.3, this Agreement shall become void and of no further force or effect (except for the provisions of Section 1.2, this Article 10, Sections 3.4(b), 4.10, 4.21, 5.10, 6.3, 6.5, 6.10, 11.3 (as it relates to claims under Section 6.5), 12.1, 12.2, 12.3, 12.5, 12.6, 12.7, 12.8, 12.10, 12.12, 12.13, 12.15, 12.16, and 12.17, all of which shall continue in full force and effect) and Seller shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of all or any portion of the Assets to any Person without any restriction under this Agreement. Notwithstanding anything to the contrary in this Agreement, the termination of this Agreement under Section 10.1 shall, subject to the remainder of this Section 10.2, not relieve any Party from liability for any failure to perform or observe in any material respect any of its agreements or covenants contained herein that are to be performed or observed at or prior to Closing. In the event this Agreement is terminated by Seller under Sections 10.1(b) or 10.1(c), all of the conditions precedent to the obligations of Purchaser set forth in Section 7.2 (other than those actions or deliveries to occur at Closing or contingent upon the satisfaction of other conditions precedent set forth in Section 7.2 at Closing) have been met (or waived in writing by Purchaser), and Seller is ready, willing and able to perform its obligations under Section 8.2), then Seller shall be entitled, at its sole and exclusive remedy, to retain the Deposit, free of any claims by Purchaser or any other Person. It is expressly stipulated by the Parties that the actual amount of Damages resulting from any termination of the type set forth in this Section 10.2 would be difficult to determine accurately because of the unique nature of this Agreement, the unique nature of the Assets, the uncertainties of applicable commodity markets and differences of opinion with respect to such matters, and that the Parties hereby agree and acknowledge that the amount of the Deposit hereunder (a) represents a reasonable

estimate of the minimum amount of Damages that the Seller would suffer as a result of such a termination and (b) represents reasonable consideration for the Seller removing the Assets from the marketplace during the period from the Execution Date until the termination hereof. In the event this Agreement is terminated by Purchaser under Sections 10.1(b) or 10.1(d), all of the conditions precedent to the obligations of Seller set forth in Section 7.1 (other than those actions or deliveries to occur at Closing or contingent upon the satisfaction of other conditions precedent set forth in Section 7.1 at Closing) have been met (or waived in writing by Seller), and Purchaser is ready, willing and able to perform its obligations under Section 8.3), then Purchaser shall receive back the Deposit, free of any claims by Seller or any other Person and Purchaser shall be entitled to seek to recover Damages from Seller equal to its actual out‑of‑pocket costs and expenses incurred in connection with the transactions contemplated by this Agreement, provided that any such recovery shall not exceed an amount equal to the Deposit. Notwithstanding anything to the contrary herein, if a Party has failed to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed at, prior to or, if Closing has occurred, after the Closing (including, if applicable, the obligation of Seller to consummate the Closing, but specifically excluding the obligation of Purchaser to consummate the Closing), the other Party may seek specific performance of such covenant or agreement at any time prior to the valid termination of this Agreement without the necessity of posting bond or furnishing other security; provided, however, Seller shall not have the right to specific performance of, or other equitable relief with respect to, the obligation of Purchaser to consummate the Closing. Each Party understands and agrees that the other Party may suffer irreparable damage as a result of it failing to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed at, prior to or, if Closing has occurred, after the Closing. Accordingly, each Party waives any right it may have to challenge the enforceability of this Agreement by a decree of specific performance and agrees it will not argue in any proceeding that the requirements for specific performance have not been met, that monetary damages constitute a sufficient remedy or make any other argument in opposition to the specific performance of this Agreement.

10.3    Distribution of Deposit Upon Termination. If this Agreement is terminated for any reason (other than a termination by Seller as permitted pursuant to Sections 10.1(b) or 10.1(c) where Seller is entitled to retain the Deposit as provided in Section 10.2), Seller shall deliver to Purchaser the Deposit, free of any claims by Seller or any other Person with respect thereto.

11.1    Assumed Obligations. Without limiting the Purchaser Group’s right to indemnification under this Article 11 or any adjustments to the Purchase Price set forth in Section 2.3, on the Closing Date, Purchaser shall assume and hereby agrees to fulfill, perform, pay, and discharge (or cause to be fulfilled, performed, paid, or discharged) all of the obligations and liabilities of Seller and its Affiliates, known or unknown, with respect to the Assets, regardless of whether such obligations or liabilities arose prior to, on, or after the Effective Time, including the following (collectively, the “Assumed Obligations”):

(a)subject to the adjustments to the Purchase Price set forth in Section 2.3, all obligations and liabilities arising from or in connection with any production, pipeline, storage, processing, or other imbalance attributable to Hydrocarbons produced from the Properties, whether before, on, or after the Effective Time, including obligations to furnish makeup gas in accordance with the terms of applicable gas sales, gathering, or transportation Contracts;

(b)obligations to pay the Purchaser Responsibility Suspense Amounts to the extent such Purchaser Responsibility Suspense Amounts are transferred to Purchaser’s control at the Closing or for which Purchaser otherwise received a downward adjustment to the Purchase Price pursuant to Section 2.3;

(c)obligations for plugging and abandonment of all of the Wells and dismantlement, decommissioning, or abandonment of all structures and Equipment included in the Assets or located on the lands covered by, or described in, the Leases (whether such Leases have terminated or expired) and restoration of the surface covered by the Assets in accordance with applicable Laws (whether or not required to be plugged, abandoned, dismantled, or restored as of the Effective Time, and whether or not the applicable Lease has terminated or expired), including any obligations to assess, remediate, remove, and dispose of NORM, asbestos, mercury, drilling fluids, chemicals, and produced waters and Hydrocarbons;

(d)subject to the terms of Article 3, Section 11.2(b)(iii) and the special warranty of Defensible Title in the Assignment and Bill of Sale, all Damages and obligations arising from, or relating to, Title Defects, deficiencies, or other title matters, whether arising or relating to periods of time before, on, or after the Effective Time;

(e)subject to the terms of Article 3 and Purchaser’s rights pursuant to Section 11.2(b)(iii) and Section 11.2(b)(i), Damages and obligations arising from, or relating to, Environmental Law, Hazardous Substances, Environmental Defects, or other environmental matters, whether arising or relating to periods of time before, on, or after the Effective Time; and

(f)Asset Taxes that are not Seller Taxes.

11.2    Indemnification.

(a)From and after Closing, subject to the terms hereof and notwithstanding any investigation or knowledge of any Person, Purchaser shall indemnify, defend, and hold harmless Seller and its Affiliates and its and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives (the “Seller Group”) from and against all Damages incurred or suffered by Seller Group:

(i)caused by, arising out of, or resulting from, the Assumed Obligations;

(ii)caused by, arising out of, or resulting from, Purchaser’s breach of any of Purchaser’s covenants or agreements contained in this Agreement; or

(iii)caused by, arising out of, or resulting from, any breach of any representation or warranty made by Purchaser in this Agreement or in the certificate delivered at Closing pursuant to Section 8.3(d);

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY INDEMNIFIED PERSON, INVITEE, OR THIRD PERSON, AND WHETHER OR NOT CAUSED BY A PRE-EXISTING CONDITION, BUT EXCLUDING THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

(b)From and after Closing, subject to the terms hereof and notwithstanding any investigation or knowledge of any Person, Seller shall indemnify, defend, and hold harmless Purchaser and its Affiliates and its and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives (“Purchaser Group”) from and against all Damages incurred or suffered by Purchaser Group:

(i)caused by or arising out of, or resulting from, the Retained Obligations;

(ii)caused by, arising out of, or resulting from, Seller’s breach of any of Seller’s covenants or agreements contained in this Agreement; or

(iii)caused by, arising out of, or resulting from any breach of any representation or warranty made by Seller in this Agreement, or in the certificate delivered at Closing pursuant to Section 8.2(e);

(c)Notwithstanding anything to the contrary contained in this Agreement, from and after Closing, Seller’s and Purchaser’s sole and exclusive remedy against each other with respect to breaches of the representations, warranties, covenants, and agreements of the Parties contained in this Agreement (excluding Sections 6.5 and 6.7, which shall also be separately enforceable by Seller and Purchaser, as applicable, pursuant to whatever rights and remedies are available to it outside of this Article 11), and the affirmations of such representations, warranties, covenants, and agreements contained in the certificates delivered by each Party at Closing pursuant to Sections 8.2(e) and 8.3(d), as applicable, as well as with respect to any matter arising under Environmental Law or relating to hazardous material is set forth in this Article 11 and if no such right of indemnification is expressly provided in this Article 11 then such claims are hereby waived to the fullest extent permitted by Law. Except for the remedies contained in this Article 11, upon Closing each Party releases, remises, and forever discharges the other and its Affiliates and its and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives from any and all suits, legal or administrative proceedings, claims, demands, Damages, losses, costs, liabilities, interest, or causes of action whatsoever, in law or in equity, known or unknown, which such Party might now or subsequently may have, based on, relating to, or arising out of this Agreement or Seller’s (or any predecessor’s) ownership, use, or operation of the Assets, or the condition, quality, status, or nature of the Assets, INCLUDING RIGHTS TO CONTRIBUTION UNDER THE COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION AND LIABILITY ACT OF 1980, AS AMENDED, THE OIL POLLUTION ACT OF 1990, AS AMENDED, BREACHES OF STATUTORY AND IMPLIED WARRANTIES, NUISANCE OR OTHER TORT ACTIONS, RIGHTS TO PUNITIVE DAMAGES, COMMON LAW RIGHTS OF CONTRIBUTION, ANY RIGHTS UNDER INSURANCE POLICIES ISSUED OR UNDERWRITTEN BY THE OTHER PARTY OR ANY OF ITS AFFILIATES, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT, OR CONCURRENT), STRICT LIABILITY, OR OTHER LEGAL FAULT OF ANY RELEASED PERSON, INVITEE, OR THIRD PARTY, AND WHETHER OR NOT CAUSED BY A PRE-EXISTING CONDITION.

(d)The Parties shall treat, for Tax purposes, any amounts paid pursuant to this Article 11 as an adjustment to the Purchase Price.

11.3    Indemnification Actions. Except as provided in this Article 11, all claims for indemnification under Section 6.5, Section 9.4 or Section 11.2 shall be asserted and resolved as follows:

(a)For purposes of this Article 11, the term “Indemnifying Person” when used in connection with particular Damages shall mean the Person having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 11, and the term “Indemnified Person” when used in connection with particular Damages shall mean a Person having the right to be

indemnified with respect to such Damages pursuant to this Article 11, Section 6.5 or Section 9.4 (including, for the avoidance of doubt, those Persons identified in Section 11.3(g)).

(b)To make a claim for indemnification under Section 6.5, Section 9.4 or this Article 11, an Indemnified Person shall notify the Indemnifying Person of its claim, 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 Person against the Indemnified Person (a “Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Claim and shall enclose a complete copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Person to give notice of a Claim as provided in this Section 11.3 shall not relieve the Indemnifying Person of its obligations under Section 6.5, Section 9.4 or this Article 11, except to the extent such failure results in insufficient time being available to permit the Indemnifying Person to effectively defend against the Claim or otherwise materially prejudices the Indemnifying Person’s ability to defend against the Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant, or agreement, the Claim Notice shall specify the representation, warranty, covenant, or agreement that was inaccurate or breached and the basis of such inaccuracy or breach.

(c)In the case of a claim for indemnification based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend and indemnify the Indemnified Person against such Claim under Section 6.5, Section 9.4 or this Article 11, as applicable. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Person admits or denies its obligation to defend the Indemnified Person, it shall be conclusively deemed obligated to provide such indemnification hereunder. The Indemnified Person is authorized, prior to and during such thirty (30) day period but prior to the Indemnifying Person admitting (or being deemed to have admitted such obligation pursuant to this Section 11.3(c)) its obligation to provide indemnification with respect to the matter in question, to file any motion, answer, or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

(d)If the Indemnifying Person admits its obligation (or is deemed to have admitted its obligation), it shall have the right and obligation to diligently defend and indemnify, at its sole cost and expense, the Claim. The Indemnifying Person shall have full control of such defense and proceedings, including, subject to the remainder of this Section 11.3(d), any compromise or settlement thereof. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Claim which the Indemnifying Person elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Person may, at its own expense, participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Person pursuant to this Section 11.3(d). An Indemnifying Person shall not, without the written consent of the Indemnified Person, settle any Claim or consent to the entry of any judgment with respect thereto that (i) does not result in a final, non-appealable, resolution of the Indemnified Person’s liability with respect to the Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Claim) or (ii) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

(e)If the Indemnifying Person does not admit its obligation or admits its obligation but fails to diligently defend, indemnify against, or settle the Claim, then the Indemnified Person shall have the right to defend against the Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s

choosing, subject to the right of the Indemnifying Person to admit its obligation to indemnify the Indemnified Person and assume the defense of the Claim at any time prior to settlement or final, non-appealable determination thereof. If the Indemnifying Person has not yet admitted its obligation to defend and indemnify the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its obligation for indemnification with respect to such Claim and (ii) if its obligation is so admitted, assume the defense of the Claim, including the power to reject the proposed settlement. Notwithstanding anything to the contrary contained herein, the defense of any Claim that principally involves Asset Taxes shall be governed by Section 9.6.

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

(g)Any claim for indemnity under Section 6.5, Section 9.4 or this Article 11 by any Affiliate, partner, member, shareholder, owner, officer, director, manager, employee, agent or representative must be brought and administered by the applicable Party to this Agreement that is related to such Person. No Indemnified Person other than Seller and Purchaser shall have any rights against Seller or Purchaser under the terms of Section 6.5, Section 9.4 or this Article 11 except as may be exercised on its behalf by Purchaser or Seller, as applicable, pursuant to this Section 11.3(g). Seller and Purchaser may elect to exercise or not exercise indemnification rights under this Section 11.3 on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Section 11.3.

11.4    Casualty and Condemnation.

(a)Subject to Seller’s representations, warranties and covenants made pursuant to this Agreement, from and after the Effective Time, if Closing occurs, Purchaser shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any Well, collapsed casing or sand infiltration of any Well) and the depreciation of any Equipment due to ordinary wear and tear, in each case, with respect to the Assets.

(b)If, after the Execution Date but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is expropriated or taken in condemnation or under right of eminent domain (each, a “Casualty Loss”), Purchaser shall, subject to the other terms and conditions of this Agreement, nevertheless be required to close and Seller, at the Closing, shall pay to Purchaser all sums paid to Seller by non-Affiliate third Persons by reason of such Casualty Loss insofar as with respect to the Assets and shall assign, transfer and set over to Purchaser or subrogate Purchaser to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards and other rights against non-Affiliate third Persons arising out of such Casualty Loss insofar as with respect to the Assets; provided, however, that Seller shall reserve and retain all rights, title, interests and claims against third Persons who are not Affiliates of Seller for the recovery of Seller’s costs and expenses incurred prior to the Closing in pursuing or asserting any such insurance claims or other rights against such third Persons with respect to any such Casualty Loss.

11.5    Limitation on Actions.

The covenants and agreements of Seller in this Agreement to be performed after the Closing Date shall survive the Closing until performed. The remainder of this Agreement shall survive the Closing and delivery of the Assignment and Bill of Sale without time limit except as may otherwise be expressly provided herein.

Purchaser’s indemnities set forth in Section 11.2(a)(i) relating to the Assumed Obligations shall survive the Closing without time limit.

(c)Seller shall not have any liability for any indemnification under Section 11.2(b)(ii) with respect to breaches of Section 6.4(d) or Section 11.2(b)(iii), except for breaches of the Fundamental Representations and the representations and warranties in Section 4.3 for which the following limitations shall not apply, for an individual matter until and unless the amount of the liability for Damages with respect to which Seller admits (or it is otherwise finally determined) that Seller has an obligation to indemnify Purchaser pursuant to the terms of Section 11.2(b)(ii) or 11.2(b)(iii) (as applicable) exceeds One Hundred Thousand Dollars ($100,000) (the “Individual Indemnity Threshold”). Without limiting the foregoing, Seller shall not have any liability for any indemnification under Section 11.2(b)(ii) with respect to breaches of Section 6.4(d) or Section 11.2(b)(iii), except for breaches of the Fundamental Representations and the representations and warranties in Section 4.3 for which the following limitations shall not apply, until and unless the aggregate amount of the liability for all Damages (i) for which Claim Notices are delivered by Purchaser under Section 11.2(b)(ii) with respect to breaches of Section 6.4(d) and Section 11.2(b)(iii), (ii) with respect to which Seller admits (or it is otherwise finally determined) that Seller has an obligation

12.6    Venue; Waiver of Jury Trial. Each Party submits to the exclusive jurisdiction of any United States federal court or Texas state court sitting in Houston, Texas with respect to any dispute, claim, or controversy arising out of, in relation to, or in connection with, this Agreement, and each of the Parties agrees that any action instituted by it against the other with respect to any such dispute, controversy, or claim (except to the extent a dispute, controversy, or claim arising out of, in relation to, or in connection with, title or environmental matters pursuant to Section 3.10 or the determination of Purchase Price adjustments pursuant to Section 8.4(b) is referred to an expert pursuant to those Sections) will be instituted exclusively in such a court.

THE PARTIES HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY ANY PARTY AGAINST ANOTHER IN ANY MATTER WHATSOEVER ARISING OUT OF, IN RELATION TO, OR IN CONNECTION WITH, THIS AGREEMENT.

12.7    Captions. The captions in this Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement.

12.8    Waivers. Any failure by any Party to comply with any of its obligations, agreements, or conditions herein contained may be waived by the Party to whom such compliance is owed by an instrument signed by the Party to whom compliance is owed and expressly identified as a waiver, but not in any other manner. No course of dealing on the part of Seller or Purchaser, or their respective Affiliates and its and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives or any failure by Seller or Purchaser to exercise any of its rights under this Agreement shall operate as a waiver thereof or affect in any way the right of such Party at a later time to enforce the performance of such provision. No waiver of, or consent to a change in, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided.

12.9    Assignment.

(a)Other than as permitted by Section 9.4 or as required by Section 2.6(k)(i), no Party shall assign or otherwise transfer all or any part of this Agreement to any third Person, nor shall any Party delegate any of its rights or duties hereunder to any third Person, without the prior written consent of the other Party and any transfer or delegation made without such consent shall be void ab initio; provided, that either Party shall be entitled to assign its rights under Section 2.6 at any time after the Closing pursuant to a sale of all or substantially all of such Party’s assets without the other Party’s consent; provided further, nothing in this Section 12.9 shall require the consent of the other Party in connection with a first Party’s

change of control, merger, consolidation or stock sale.
