 22 

 2.7 Post-Closing Adjustment. 

(a) Revised Closing Statement. On or before the date that is ninety (90) days after the Closing Date, Buyer shall prepare and
deliver to Seller a revised Closing Statement setting forth its assessment of the final Interim Expense Amount, the final Interim Revenue Amount, the final Cash Amount as of the Closing Date, the final Aggregate Closing Defect Amount, the portion of
the Payoff Amount directly funded by Buyer and the amount of any Transaction Expenses actually funded by Buyer and the final Closing Date Working Capital, in each case as of or on the Closing Date, as applicable. For the avoidance of doubt, the
Aggregate Closing Defect Amount shall be final as of the Closing, and no Title Defect shall be affected by the review and adjustment process contemplated by this Section 2.7 and shall be governed exclusively by Section 2.9.
Buyer shall provide to Seller such data and information as Seller may reasonably request supporting the amounts reflected on the revised Closing Statement (and reasonable access to Buyer’s personnel, including internal accountants) to permit
Seller to perform or cause to be performed an audit of the revised Closing Statement, at Seller’s expense. The revised Closing Statement shall become final and binding upon the Parties on the date (the “Final Settlement Date”)
that is thirty (30) days following receipt thereof by Seller unless Seller gives Notice of its disagreement (“Notice of Disagreement”) to Buyer prior to such date, it being understood that the Notice of Disagreement shall not
include any Title Defects or Environmental Defects or any other matters contemplated by Section 2.9. Any Notice of Disagreement shall specify in reasonable detail the dollar amount, nature, and basis of any disagreement so asserted. If a
Notice of Disagreement is received by Buyer by the date specified in this Section 2.7(a), then the Closing Statement (as revised in accordance with Section 2.7(b) below) shall become final and binding on the Parties on, and
the Final Settlement Date shall be, the earlier of (i) the date upon which Seller and Buyer agree in writing with respect to all matters specified in the Notice of Disagreement and (ii) the date upon which the Arbitrator’s Closing
Statement (as hereinafter defined) is issued by the Closing Statement Arbitrator (as hereinafter defined). 
 (b) Final Closing
Statement. During the thirty (30) days following the date upon which Buyer receives a Notice of Disagreement, Seller and Buyer shall use commercially reasonable efforts to attempt to resolve in writing any differences that they may have
with respect to all matters specified in the Notice of Disagreement. If at the end of such thirty (30) day period (or earlier by mutual agreement), Buyer and Seller have not reached agreement on such matters, the matters that remain in dispute
(and only such matters) shall promptly be submitted to Deloitte & Touche LLP (the “Closing Statement Arbitrator”) for review and final and binding resolution. If Deloitte & Touche LLP is unable or unwilling to
serve as an arbitrator hereunder, then Seller and Buyer shall, in good faith, mutually agree upon an independent national accounting firm who has not represented either Party or its Affiliates in any material matter at any time during the two
(2) year period of time immediately preceding its designation hereunder, to serve as the Closing Statement Arbitrator. Buyer and Seller shall, not later than seven (7) days prior to the hearing date set by the Closing Statement Arbitrator,
each submit a written brief to the Closing Statement Arbitrator (and a copy thereof to the other Party on the same day) with proposed dollar figures for settlement of the disputes as to the amount of the Purchase Price Adjustment (together with a
proposed Closing Statement that reflects such 

  
 23 

 
figures) consistent with their respective calculations delivered pursuant to Section 2.7(a). The hearing will be scheduled seven (7) days following submission of the settlement
briefs, or as soon thereafter as is acceptable to the Closing Statement Arbitrator, and shall be conducted on a confidential basis. The Closing Statement Arbitrator shall consider only those items or amounts in the Closing Statement which were
identified in the Notice of Disagreement and such written briefs and which remain in dispute and the Closing Statement Arbitrator’s decision resolving the matters in dispute shall be based upon and be consistent with the terms and conditions in
this Agreement, it being understood that the Closing Statement Arbitrator may not consider, and the decision of the Closing Statement Arbitrator shall have no impact on, the Title Defect Amount or the Environmental Defect Amount. In deciding any
matter, the Closing Statement Arbitrator (i) shall be bound by the provisions of this Section 2.7 and the related definitions and (ii) may not assign a value to any disputed item greater than the greatest value for such item
claimed by either Seller or Buyer or less than the smallest value for such item claimed by Seller or Buyer in their respective calculations delivered pursuant to Section 2.7(a). The Closing Statement Arbitrator shall render a decision
resolving the matters in dispute (which decision shall include a written statement of findings and conclusions) promptly after the conclusion of the hearing, unless the Parties reach agreement prior thereto and withdraw the dispute from arbitration.
The Closing Statement Arbitrator shall provide to the Parties explanations in writing of the reasons for its decisions regarding the Purchase Price Adjustment and shall issue the Final Closing Statement (as defined below) reflecting such decision,
which shall set forth the Purchase Price Adjustment and the Adjusted Purchase Price as determined by the Closing Statement Arbitrator pursuant to this Section 2.7. The decision of the Closing Statement Arbitrator shall be (i) final
and binding on the Parties and (ii) final and non-appealable for all purposes hereunder; provided, however, that such decision may be reviewed, corrected or set aside by a court of competent jurisdiction, but only if and to the
extent that the Closing Statement Arbitrator is found by such court of competent jurisdiction to have made mathematical errors with respect to its decision or to have manifestly violated the express terms of this Section 2.7 (including
the related defined terms set forth in Section 1.1). The cost of any arbitration (including the fees and expenses of the Closing Statement Arbitrator) under this Section 2.7(b) shall be borne entirely by the Party awarded the
smaller percentage of the disputed amount by the Closing Statement Arbitrator. The fees and disbursements of Buyer’s independent auditors and other costs and expenses incurred in connection with the services performed with respect to the
Closing Statement shall be borne by Buyer and the fees and disbursements of Seller’s independent auditors and other costs and expenses incurred in connection with their preparation of the Notice of Disagreement shall be borne by Seller. As used
in this Agreement, the term “Final Closing Statement” shall mean the revised Closing Statement described in Section 2.7(a), as prepared by Buyer and as may be subsequently adjusted to reflect any subsequent written
agreement between the Parties with respect thereto, or if submitted to the Closing Statement Arbitrator, the Arbitrator’s Closing Statement (“Arbitrator’s Closing Statement”) as described in this
Section 2.7(b). 
 (c) Final Settlement. If the Adjusted Purchase Price set forth on the Closing Statement delivered
pursuant to Section 2.4 exceeds the Adjusted Purchase Price set forth on the Final Closing Statement, then Seller shall pay Buyer such excess amount, together with interest thereon, from the Closing Date to (but not including) the date
on which such payment is paid, at the rate of three percent (3%) per annum calculated and payable in accordance with Section 2.7(d). If the Adjusted Purchase Price set forth on the Final Closing Statement exceeds the Adjusted
Purchase Price set forth on the Closing Statement delivered 

  
 24 

 
pursuant to Section 2.4, then Buyer shall pay Seller such excess amount, together with interest thereon, from the Closing Date to (but not including) the date on which such payment is
paid, at the rate of three percent (3%) per annum calculated and payable in accordance with Section 2.7(d). Any adjustments to the Adjusted Purchase Price made pursuant to this Section 2.7(c) shall be paid by wire
transfer in immediately available funds to an account specified by the Party to whom such payment is owed within five (5) Business Days after the Final Settlement Date. 

(d) Interest. All computations of interest with respect to any payment due to a Person under this Agreement shall be based on the
Interest Rate on the basis of a year of 365 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest is payable. Whenever any payment under this Agreement
will be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall be included in the computation of payment of interest. 

2.8 Purchase Price Allocation. The Parties agree that the transactions contemplated hereby will be treated for federal income Tax
purposes as a purchase and sale of the Company Assets. Seller shall prepare, and deliver to Buyer, more than thirty (30) days before Closing, an allocation of the Purchase Price and assumed obligations among the Company Assets in accordance
with Section 1060 of the Code and the Treasury regulations promulgated thereunder (the “Allocation”). Buyer shall have twenty (20) days from the receipt of the Allocation or any update thereto to review and comment on the
Allocation, after which Seller and Buyer shall reasonably agree on such Allocation by the time of the Closing. Seller shall use commercially reasonable efforts to update the Allocation in a manner consistent with Section 1060 of the Code
following any adjustments to the Purchase Price pursuant to this Agreement. Seller shall provide Buyer with any such updated Allocation, and Buyer shall have thirty (30) days from the receipt of the Allocation or any update thereto to review
and comment on such adjustments to the Allocation, after which Seller and Buyer shall reasonably agree on such adjustments. Disputes under this Section 2.8 shall be resolved under the procedures described in Section 2.7(b).
Seller and Buyer shall report consistently with the Allocation in all Tax Returns, including IRS Form 8594, which Seller and Buyer shall timely file with the IRS, and neither Seller nor Buyer shall take any position in any return that is
inconsistent with the Allocation, as adjusted, in each case, unless required to do so by a final determination as defined in Section 1313 of the Code. 

2.9 Title and Environmental Review. 

(a) Independent Examination. Subject to the other provisions of this Section 2.9, Buyer shall have the right during the
period beginning on the date hereof and continuing through the date that is [omitted] from the date hereof (the “Examination Period”) to conduct land and title work and diligence on the Leases and Units and environmental
assessments, independently on its own behalf and account, to (i) examine and make copies of all Records, (ii) conduct an on-site inspection of all well sites and appurtenant equipment and facilities located in the Units and on the lands
covered by the Leases or lands spaced, pooled or unitized therewith, and (iii) conduct any other reasonable examinations, inspections, and investigations that Buyer considers appropriate for its due diligence review of such matters
(“Independent Title and Environmental Review”) (such environmental assessments to be 

  

	*	Portions of this exhibit (indicated by [omitted]) have been omitted pursuant to a request for confidential treatment and have been separately filed with the Securities and Exchange Commission. 

 
 25 

 
conducted by [omitted] or another reputable environmental consulting or engineering firm selected by Buyer and approved by Seller, such approval not to be unreasonably withheld,
conditioned or delayed), and may, by delivery of Notice to Seller prior to the expiration of the Examination Period (or, in the case of Special Warranty Title Defects, prior to [omitted]), assert the existence of an alleged Title Defect with
respect to any of the Leases of Lavaca and/or Units or an Environmental Defect (“Defect Notice”). All such due diligence activities shall be conducted by Buyer at Buyer’s sole cost, risk, and expense. No claims for Title
Defects or Environmental Defects arising at Leases and Units may be submitted after the Examination Period, and any matters that may otherwise constitute Title Defects or Environmental Defects arising at Leases and Units, but for which Buyer has not
delivered a Defect Notice to Seller prior to the expiration of the Examination Period, shall be deemed to have been waived by Buyer for all purposes and shall constitute Permitted Encumbrances; provided, however, that Buyer may make
claims for Special Warranty Title Defects on or before [omitted]. From and after the date hereof until the expiration of the Examination Period, Seller shall (i) allow, and shall cause each of its Representatives to allow, Buyer and its
Representatives reasonable access during normal business hours to Seller’s personnel and Employees, facilities, properties, and Records in connection with the Independent Title and Environmental Review, and (ii) make available to Buyer and
its Representatives, upon reasonable notice during normal business hours, Seller’s personnel and employees knowledgeable with respect to title and environmental matters relating to the Companies and the Company Assets, provided that such
Independent Title and Environmental Review shall be conducted in a manner that does not unreasonably interfere with the operations of Seller and its Affiliates. Seller shall cooperate with Buyer to facilitate Buyer’s diligence of the Company
Oil and Gas Properties, including its inspection of the Records. Seller shall use its commercially reasonable efforts to obtain permission from any Third Party operator of any wells located in the Units or on the lands covered by the Lease or on
lands spaced, pooled or unitized therewith to provide Buyer with reasonable access to the physical premises of each such well site and the equipment and facilities appurtenant thereto. Prior to the Closing Date, Buyer shall not disclose any
environmental sampling and testing results to any Third Party (other than Buyer’s Representatives) unless required by applicable Law, provided that if Buyer believes it may have an obligation to disclose such results to a Third Party it
will promptly notify and consult with Seller regarding such belief and will in good faith consider any information Seller provides in evaluating such potential disclosure obligation, and, provided further, that if Seller concludes that
disclosure is required Seller may make such disclosure, it being understood that if Seller fails to timely make such disclosure and Buyer is legally obligated to do so, Buyer shall be entitled to make the relevant disclosure as required. During the
Examination Period, Buyer shall provide Notice to Seller of any Title Defect or Environmental Defect as promptly as practicable after Buyer has actual knowledge of any matter that Buyer considers to be a Title Defect or an Environmental Defect and
sufficient information to provide the items required to be included in a Defect Notice, as provided in Section 2.9(c); provided that the failure to provide such notice shall not prejudice Buyer’s rights hereunder with respect
to such Title Defect or Environmental Defect, except insofar as Seller is prejudiced by such failure; provided further that, to the extent that [omitted]. The fees, costs, and expenses incurred by Buyer in conducting its
Independent Title and Environmental Review or any other due diligence investigation shall be borne by Buyer for its sole account.

 26 

 (b) Allocated Values. “Allocated Value” means (i) for each Lease of
Lavaca identified on Exhibit C-2 (or portion thereof) located to the west of the Demarcation Line that is not included within a Unit, the product of (1) the Net Mineral Acres for such Lease set forth on Exhibit C-2, multiplied by
(2) a fraction, the numerator of which is [omitted] and the denominator of which is the excess of (a) the aggregate Net Mineral Acres for all Leases of Lavaca set forth on Exhibit C-2 (or portions thereof) that are located to
the west of the Demarcation Line that is not included within a Unit, over (b) the Net Mineral Acres for all Leases of Lavaca set forth on Exhibit C-3 that are located to the west of the Demarcation Line and (ii) for each Unit, the
dollar value set forth on Exhibit D-1 for each Unit of DeWitt and Exhibit D-2 for each Unit of Lavaca under the column labeled “Allocated Value”. Seller and Buyer hereby accept such Allocated Values for the purposes of
determining any Title Defect Amounts or Environmental Defect Amounts in respect of each applicable Lease of Lavaca or Unit, but otherwise make no representation or warranty as to the accuracy of such values. 

(c) Defect Notice. Each Defect Notice asserting a claim for a Title Defect or Environmental Defect with respect to any Lease of Lavaca
or Unit shall be in writing and shall include: 
 (i) a description in reasonable detail of the alleged Title Defect or Environmental
Defect; 
 (ii) each Lease of Lavaca or Unit affected by the alleged Title Defect or Environmental Defect; 

(iii) the aggregate Allocated Value of each Lease of Lavaca or Unit affected by the alleged Title Defect or Environmental Defect; 

(iv) if the Title Defect involves Deficiency Acres in a Lease of Lavaca, the number and location of such Deficiency Acres; 

(v) if the Title Defect is a Lien, Buyer’s good faith estimate of the cost to remove such Lien; 

(vi) any supporting documents in Buyer’s possession and a summary of any documents not in Buyer’s possession, in each case, that are
reasonably necessary for Seller (as well as any experienced title attorney, examiner or environmental consultant or advisor hired by Seller) to verify the existence and magnitude of the alleged Title Defect or Environmental Defect; and 

(vii) the amount by which Buyer reasonably believes the Allocated Value of such Lease of Lavaca or Unit is reduced by the alleged Title Defect
or Environmental Defect and the computations and information upon which Buyer’s belief is based. 
 (d) Cure by Seller. To the
extent that it is agreed or determined that there exists a Title Defect or Environmental Defect for which a Defect Notice was timely submitted, Seller shall have the right, but not the obligation, to cure such Title Defect or Environmental Defect
during the period following the date upon which Seller receives such Defect Notice until the date that is [omitted] from such date (the “Cure Period”) by (i) removing or otherwise curing the matter causing the Title
Defect or Environmental Defect, at Seller’s sole cost and expense, (ii) in the case of a Title Defect arising under clause (i) of the Defensible Title 

  

	*	Portions of this exhibit (indicated by [omitted]) have been omitted pursuant to a request for confidential treatment and have been separately filed with the Securities and Exchange Commission. 

 
 27 

 
definition, obtaining, and assigning to Lavaca such Replacement Leases as are necessary for Lavaca to receive the Deficiency Acres (as defined below) in the tract covered by the Lease to which
such Title Defect has been asserted, in which case the newly acquired Replacement Leases shall be deemed to be part of the Company Assets for all purposes hereof, or (iii) in the case of a Special Warranty Title Defect, assigning or causing to
be assigned to the applicable Company an interest in the affected Lease or Unit such that such Company would own such interests as it would have owned had such Title Defect not existed. 

(e) Defect Amount. If Seller has not cured a Title Defect or Environmental Defect within the Cure Period for such Title Defect or
Environmental Defect as provided above, then the amount of such Title Defect (the “Title Defect Amount”) or Environmental Defect (the “Environmental Defect Amount”) (each such amount, a “Defect
Amount”) shall be determined as follows: 
 (i) if Buyer and Seller agree in writing on the Title Defect Amount for a Title Defect,
that amount shall be the Title Defect Amount, and if Buyer and Seller agree in writing on the Environmental Defect Amount for an Environmental Defect, that amount shall be the Environmental Defect Amount; 

(ii) if the Title Defect is a Lien other than a Permitted Encumbrance, then the Title Defect Amount for such Title Defect shall be the amount
necessary to remove such Lien; 
 (iii) if the Title Defect represents a discrepancy whereby the Net Revenue Interest for any Unit that a
Company is entitled to receive is less than the Net Revenue Interest stated in Exhibit D-1 or Exhibit D-2 with respect to such Unit as provided in clause (ii) of the definition of “Defensible Title,” then the Title
Defect Amount, which shall not exceed the Allocated Value for such Unit shall as provided be the product of (x) the Allocated Value of such Unit, multiplied by (y) a fraction, the numerator of which is the amount by which the Net
Revenue Interest stated in Exhibit D-1 or Exhibit D-2 with respect to such Unit exceeds the actual Net Revenue Interest with respect to such Unit, and the denominator of which is the Net Revenue Interest stated in Exhibit D-1 or
Exhibit D-2 with respect to such Unit; provided, that if the Title Defect does not affect the Unit throughout its entire productive life, the Title Defect Amount determined under this Section 2.9(e)(iii) shall be reduced to
take into account the applicable time period only; 
 (iv) if the Title Defect represents a discrepancy whereby a Company is obligated to
bear greater than the percentage or percentages set forth in Exhibit D-1 or Exhibit D-2 with respect to any Unit as such Company’s Working Interest in such Unit (unless there is a corresponding increase in such Company’s Net
Revenue Interest in any such Unit) as provided in clause (ii) of the definition of “Defensible Title”, then the Title Defect Amount, which shall not exceed the Allocated Value for such Unit, shall be (x) the Allocated Value of
such Unit, multiplied by (y) a fraction, the numerator of which is the amount by which the Working Interest stated in Exhibit D-1 or Exhibit D-2 exceeds the actual Working Interest with respect to such Unit, and the
denominator of which is the percentage obligation stated in Exhibit D-1 or Exhibit D-2 with respect to such Unit; provided, that if the Title Defect does not affect the Unit throughout its entire productive life, the Title
Defect Amount determined under this Section 2.9(e)(iv) shall be reduced to take into account the applicable time period only; 

  
 28 

 (v) for Environmental Defects, the Environmental Defect Amount is the amount necessary to
remediate such Environmental Defect, by satisfying the obligations required to address any breach of Environmental Laws and any Remediation regarding the Environmental Obligation giving rise to such Environmental Defect, in the most cost effective
manner reasonably available for continuation of the current use of the Lease or Unit; 
 (vi) if the Title Defect is that the sum of the
aggregate Net Mineral Acres covered by a Lease of Lavaca is less than the Net Mineral Acres shown for such Lease in Exhibit C-2 (the difference being the “Deficiency Acres”), then the Title Defect Amount, which shall not
exceed the Allocated Value for such Lease of Lavaca, shall be the product of (x) the Allocated Value for such Lease multiplied by (y) a fraction, the numerator of which is the number of Deficiency Acres (less, to the extent
applicable, any otherwise Deficiency Acres that are acres included in any portion of a Lease that has been pooled or unitized for purposes of developing any Unit) for such Lease and the denominator of which is the Net Mineral Acres shown for such
Lease in Exhibit C-2; 
 (vii) if the Title Defect is a Special Warranty Title Defect and relates solely to depths other than the
Eagle Ford Formation, then the Title Defect Amount, which shall not exceed the Allocated Value for such Lease of Lavaca or such Unit, will be the reduction in value of the relevant Lease of Lavaca or Unit resulting from such Title Defect;
provided, that, if the Title Defect does not affect the Unit throughout its entire productive life, the Title Defect Amount determined under this Section 2.9(e)(vii) shall be reduced to take into account the applicable time period
only; 
 (viii) if the Title Defect arises due to a Company’s inability to participate in any additional oil and/or gas well that could
otherwise have been drilled to, completed in, and produced from the Eagle Ford Formation on lands in that Unit if the Company had not lost the right to drill any such well to, complete each such well in, and produce each such well from the Eagle
Ford Formation because of the failure of any Person to timely drill, complete and produce any well in that Unit, then the Title Defect Amount shall be the reduction in value of the relevant Unit resulting from such Title Defect; 

(ix) notwithstanding anything to the contrary in this Section 2.9, the Title Defect Amounts shall not exceed (x) with respect
to each Unit, the Allocated Value for such Unit and (y) with respect to each Lease of Lavaca, the Allocated Value for such Lease; and 

(x) the Defect Amount with respect to a Title Defect or Environmental Defect shall be determined without duplication of any costs or losses
included in any other Title Defect Amount or Environmental Defect Amount hereunder. 

  
 29 

 (f) No Agreement. If the Parties cannot agree upon the existence of a Title Defect or
Environmental Defect with respect to an affected Unit or Lease or cannot mutually agree upon any Defect Amount prior to the expiration of the Cure Period, such dispute shall be exclusively and finally resolved by arbitration pursuant to this
Section 2.9(f). In the event of such a dispute, upon the expiration of the applicable Cure Period, the Parties promptly shall meet and attempt to mutually agree on a resolution. If the Parties are unable to resolve the disagreement
within five (5) days after the expiration of the applicable Cure Period, then the disagreement shall be resolved by an attorney who is board certified by the State of Texas in oil, gas and mineral law, with at least ten (10) years’
experience in oil and gas title (as to Title Defects) and environmental (as to Environmental Defects) matters in the State of Texas, who shall serve as the arbiter(s) of any such disagreements (the “Title Arbitrator”). In the event
that both Title Defects and Environmental Defects are the subject of dispute, the Parties will select two Title Arbitrators (one for each type of defect). The Title Arbitrator shall be selected by mutual agreement of the Parties, or absent such
agreement, within ten (10) days after the end of the last Cure Period arising hereunder for Title Defects or Environmental Defects, as applicable, asserted during the Examination Period or within ten (10) days after the end of the Cure
Period with respect to any Special Warranty Title Defect asserted after the Examination Period, in each case, by the office of the American Arbitration Association in Dallas, Texas. The Title Arbitrator shall not have worked as an employee,
consultant or outside counsel for either Party or the Affiliates of either Party during the five (5) year period preceding the arbitration or have any financial interest in the dispute. The arbitration proceeding shall be held in Harris County,
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 2.9(f), which shall prevail in the event of
any such conflict. Within three (3) Business Days following the selection of the Title Arbitrator, the Parties shall submit to the Title Arbitrator, (i) this Agreement, with specific references to this Section 2.9,
(ii) the Defect Notices pertaining to the matters in dispute and all supporting materials thereto originally provided by Buyer to Seller, and (iii) Seller’s written response to such Defect Notices and supporting materials provided by
Seller in connection with such response. The Title Arbitrator shall resolve the disputed Title Defects and Environmental Defects, and related Title Defect Amounts and Environmental Defect Amounts that are the subject of this Section 2.9
based only on the foregoing submissions and any written responses provided by the Parties to a query from the Title Arbitrator. The Title Arbitrator’s determination of the disputed Title Defects and Environmental Defects (the “Title
Arbitration Decision”) shall be made within fifteen (15) days after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal; provided, however, within five
(5) days after a Party receives the Title Arbitration Decision, that Party may request the Title Arbitrator to reconsider the Title Arbitration Decision because that Party reasonably believes that the Title Arbitration Decision contains or is
based upon mathematical errors or a manifest violation of the express terms of this Section 2.9 (including the related defined terms included in Section 1.1). In making its determination, the Title Arbitrator shall be bound
by the rules set forth in this Section 2.9 and this Agreement. Additionally, the Title Arbitrator may consult with and engage disinterested Third Parties to advise the Title Arbitrator, including landmen, other title attorneys,
environmental consultants and petroleum engineers. The Title Arbitrator shall act as an expert for the limited purpose of determining the existence of a Title Defect or Environmental Defect and the specific disputed Title Defect Amounts and
Environmental Defect Amounts submitted by any Party and may not award damages, interest, or penalties to either Party with respect to any other matter. Each of the Parties shall bear its own fees (including legal fees) and other costs of presenting
its case. The costs and expenses of the Title Arbitrator shall be borne by the Parties in inverse proportion as they shall prevail (by dollar amounts) in all matters in dispute.

(“Covered Environmental Matters”) are set forth in this Section 2.9, and except as provided in Section 6.1(b), represent Buyer’s sole and exclusive remedies with respect to matters that could be asserted as

(i) Remedy for Title Defect. Buyer’s remedy for any Title Defect that is asserted during the Examination Period but that is not
cured prior to the expiration of the Cure Period for such Title Defect shall be the adjustment to the Purchase Price pursuant to Section 2.2(c)(iii). In the event of any Special Warranty Title Defect asserted after the Examination Period
that is not cured prior to the expiration of the Cure Period for such Special Warranty Title Defect, upon determination of the Title Defect Amount with respect thereto pursuant to this Section 2.9, Buyer shall be entitled to recover from
the Holdback Amount under the Escrow Agreement, as its sole recourse in respect of such Special Warranty Title Defect, an amount equal to such Title Defect Amount.

Seller (to the extent such properties, books, Contracts and records of Seller relate to the Companies) and the Companies and to appropriate officers and employees of Affiliates of Seller and the Companies as are reasonably identified by Buyer as
being relevant information relating to the Companies and their Affiliates and shall furnish such authorized Representatives with all financial and operating data and other information concerning the affairs of the Companies as Buyer and such
Representatives may reasonably request. Seller shall have the right to have a Representative present at all times during any such inspections, interviews, and examinations, provided that Seller shall not use such right to unreasonably delay
or prohibit Buyer’s investigation rights under this Agreement. Additionally, Buyer shall hold in confidence all such information on the terms and subject to the conditions contained in the Confidentiality Agreement. Notwithstanding the
foregoing, Buyer shall have no right of access to, and Seller shall have no obligation to provide to Buyer, information relating to: (i) bids received from others in connection with the transactions contemplated by this Agreement (or similar
transactions) and information and analyses (including financial analyses) relating to such bids; (ii) any information to the extent such information is subject to an attorney-client or attorney work product privilege; or (iii) any
information the disclosure of which would result in a violation of Law or breach of Contract; provided that in the case of clauses (ii) and (iii), Seller shall use its commercially reasonable efforts to make appropriate substitute
disclosure arrangements with respect to such information. All requests for information made under this Section 6.3(a) shall be directed to the Person designated by Seller in a Notice delivered to Buyer, and all such information provided
shall be subject to the Confidentiality Agreement. For the avoidance of doubt, Buyer will have no right to access any information regarding any of Seller’s Affiliates other than as expressly provided for in this Section 6.3(a). 

  
 52 

 (b) Confidentiality Agreement. The Confidentiality Agreement, except to the extent
modified herein, will remain in full force and effect; provided, however, that, subject to the provisions of Section 6.14, upon Closing, the Confidentiality Agreement shall terminate, and Seller shall, and shall cause its
Affiliates to, not make disclosure to Third Parties of any confidential or proprietary information relating to any Company, the Company Assets or their business, except with the prior consent of Buyer or as required by Law and Buyer shall, and shall
cause its Affiliates to, not make disclosure to Third Parties of any confidential or proprietary information relating to Sellers, its Affiliates (other than the Companies) and their respective businesses, except with the prior consent of Seller or
as required by Law. At Closing, Seller will, or will cause its applicable Affiliates to, assign to a Company the benefits under any and all Applicable Confidentiality Agreements. 

(c) Contact with Customers, Suppliers and Other Business Relations. Prior to the Closing, Buyer and Buyer’s Representatives shall
contact and communicate with the employees, customers, suppliers and other business relations of the Companies and their Affiliates in connection with the transactions contemplated hereby only with the prior written consent of Seller, such consent
not to be unreasonably withheld. Upon request by Buyer, to the extent such consent is granted, Seller shall use reasonable best efforts to facilitate communications between Buyer and the employees, customers, suppliers and other business relations
of the Companies. 
 (d) Site Access. Buyer and Buyer’s Representatives shall not have access to, and shall not be permitted to
conduct any environmental due diligence with respect to any Company Assets where Seller does not have the authority to grant access for due diligence purposes (provided, however, Seller shall use its commercially reasonable efforts to
obtain permission from any Third Party to allow Buyer and Buyer’s Representatives such access provided Buyer agrees to comply with all of Third Party’s company safety and environmental policies). Buyer and Buyer’s Representatives
shall, if requested by any such Third Party, enter into customary confidentiality and/or indemnification agreements prior to any physical inspection of any Company Assets. To the extent Buyer or any of Buyer’s Representatives are afforded
access to any such site, they will obey all rules and regulations required by the Third Party granting such access to be observed with respect to such site. To the extent that such access is not granted, the provisions of Section 2.9 of
this Agreement relating to environmental matters shall be inapplicable to the related Company Assets. 
 (e) Indemnity. Buyer shall
indemnify Seller and its Affiliates and their respective Representatives from and against any and all liabilities, damages, losses, costs, and expenses arising out of or in connection with any site visits or inspections of the Company Assets or any
other properties of the Companies or any of their Affiliates by Buyer and its Representatives, [omitted].

 53 

 (f) Applicable Confidentiality Agreements. Seller agrees that it shall not, and it shall
cause each of its Affiliates not to, release any Third Party from, or waive any provisions of, any Applicable Confidentiality Agreement and Seller will, and will cause each of its Affiliates to, use its best efforts to enforce any such agreement at
the request of or on behalf of Buyer, including initiating and prosecuting litigation seeking appropriate equitable relief (where available) and, to the extent applicable, damages. Immediately after the execution and delivery of this Agreement,
Seller will, and will instruct its and each of its Affiliate’s officers, directors, employees and Representatives to, cease and terminate any existing activities, discussions or negotiations with any parties conducted heretofore with respect to
any possible acquisition of all or any portion of the Interests, any other equity interest in any of the Companies or any material interest in any of the Company Assets. Seller agrees that it shall, and it shall cause each of its Affiliates to,
(i) take the necessary steps to promptly inform its officers, directors and Representatives involved in the transactions contemplated by this Agreement of the obligations undertaken in this Section 6.3(f) and (ii) request each
Person who has heretofore executed an Applicable Confidentiality Agreement to return or destroy (which destruction shall be certified in writing by an executive officer of such Person to the extent Seller can require such action pursuant to the
relevant Applicable Confidentiality Agreement) all confidential information heretofore furnished to such Person by or on its behalf. 
 6.4
Consents. 
 (a) Buyer and Seller shall (and shall each cause their respective Affiliates to) use reasonable best efforts to obtain,
and to cooperate in obtaining, all consents and approvals of Third Parties that any of Buyer, Seller, or their respective Affiliates are required to obtain in order to consummate the transactions contemplated hereby; provided that, the
Parties shall not be required to pay or commit to pay any amount to (or incur any obligation in favor of) any Person from whom any such consent may be required (other than filing or application fees with respect to Governmental Authorities). 

(b) Prior to the Closing, Buyer and Seller shall (and shall each cause their respective Affiliates to) [omitted] to obtain the consent

Buyer acknowledges and agrees that, following the Closing, the Units set forth on Schedule 6.4(b) will continue to be operated by GeoSouthern on behalf of the Working Interest owners therein. Buyer and its Affiliates, and their respective
Representatives, will provide to GeoSouthern and the lessor of such Units the cooperation necessary to facilitate the operation of such Units. 

6.5 Efforts; Regulatory Filings. 

(a) Upon the terms and subject to the conditions set forth in this Agreement, Buyer and Seller will use their respective reasonable best
efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Party hereto in doing, all things reasonably necessary, proper or advisable to consummate and make effective, in the most
expeditious manner practicable, the transactions contemplated by this Agreement, including using reasonable best efforts to (i) cause the conditions to the transactions contemplated hereby set forth in Article 8 to be satisfied;

of its Affiliates (other than the Companies) after the Closing); and 
 (vii) use reasonable best efforts to contest and resist any action
or Proceeding instituted (or threatened in writing to be instituted) by any Governmental Authority challenging the transactions contemplated by this Agreement as in violation of any Law.

the Companies shall not be required to agree to any undertaking or restriction that would take effect prior to, or not be conditioned upon, consummation of the Closing or that would bind Buyer or any of its Affiliates (including the Companies after
the Closing in any material respect) and (ii) contest and resist any action or Proceeding instituted (or threatened in writing to be instituted) by any Governmental Authority challenging the transactions contemplated by this Agreement as a
violation of any Law. 
 (e) Notice. If a Party intends to participate in any meeting with any Governmental Authority with respect to
such filings, it shall give the other Party reasonable prior Notice of such meeting and if commercially practicable and permitted by such Governmental Authority, an opportunity to attend such meeting. 

6.6 Books and Records. From and after the Closing Date, subject to Section 6.3(b), Seller may retain a copy of any or all
of the Due Diligence Information and all other books and records relating to the business or operations of the Companies on or before the Closing Date that are required by Seller to comply with legal obligations or that relate to parts of the
business of Seller and/or its Affiliates. 
 6.7 Replacement of Guarantees. 

(a) Buyer shall use its reasonable best efforts to cause itself, one of its Affiliates or the Companies to be substituted in all respects for
Seller and its other Affiliates, and for Seller and its other Affiliates to be released, effective as of the Closing or (if such substitution and release cannot be effected as of the Closing) as soon as possible after the Closing, in respect of all
obligations of Seller and any of its other Affiliates under each guarantee, indemnity, surety bond, letter of credit, Contract, letter of comfort or other obligation relating to the Companies and the Company Assets set forth on Schedule 6.7
(collectively, the “Indemnified Guarantees”); provided, that Buyer shall not be required to agree to waive any rights (or to cause any Company to waive any rights) or to provide any other payment or consideration in order to
obtain such release. For any Indemnified Guarantee for which Buyer, one of its Affiliates or the Companies, as applicable, is not substituted in all respects for Seller and its Affiliates (and for which Seller and its Affiliates are not released)
effective as of Closing, Buyer shall continue to use its reasonable best efforts and shall cause its Affiliates and the Companies to use their reasonable best efforts to effect such substitution and release after the Closing. 

(b) After the Closing, Buyer and the Companies, jointly and severally, shall forever indemnify, defend and hold harmless Seller and any of its
Affiliates against any liabilities, damages, losses, costs, and expenses relating to or arising from events occurring after the Closing that Seller or any of its Affiliates suffers, incurs or is liable for by reason of or arising out of or in
consequence of: (i) Seller or any of its Affiliates issuing, making payment under, being required to pay or reimburse the issuer of, or being a party to, any Indemnified Guarantee; (ii) any claim or demand for payment made on Seller or any
of its Affiliates with respect to any of the Indemnified Guarantees; or (iii) any Proceeding by any Person who is or claims to be entitled to the benefit of or claims to be entitled to payment, reimbursement or indemnity with respect to any
Indemnified Guarantees. 

  
 56 

 6.8 Shared Contracts. Buyer acknowledges the Contracts with Third Parties set forth on
Schedule 6.8 to which one or more of the Companies and Seller or one or more Affiliates of Seller are parties directly benefit both Seller or an Affiliate of Seller (other than the Companies) and one or more of the Companies (the
“Shared Contracts”). Seller shall use its reasonable best efforts to cause each Shared Contract that is not a Unit Operating Agreement to be replaced with a separate Contract that provides the applicable Company with rights and
obligations substantially similar to the rights and obligations contained in such Shared Contract of such Company and Seller (or any Affiliate of Seller party to such Shared Contract), and Buyer shall cooperate with Seller with respect thereto;
provided that, the Parties shall not be required to pay or commit to pay any amount to (or incur any obligation in favor of) any Person from whom any such consent may be required in connection with the separation or replacement of any Shared
Contract. If the Parties are not able to effect the separation of a Shared Contract prior to the Closing as a result of any required approval or consent of a Third Party, then, until such actions can be effected, to the extent permissible under
applicable Law and the terms of such Shared Contract, the Parties shall enter into alternative arrangements intended to provide the applicable Company with the benefits of such Shared Contract and to put the Parties in the same economic position as
if such Shared Contract were separated as contemplated in this Section 6.8 prior to the Closing. Buyer acknowledges that Seller shall have no obligations under this Section 6.8 with respect to any Shared Contract that is a
Unit Operating Agreement. 
 6.9 Use of GeoSouthern Marks. The Parties acknowledge that GeoSouthern Marks appear on some of the
Company Assets, including signage on the Company Assets. Buyer acknowledges and agrees that it obtains pursuant to this Agreement or otherwise no right, title, interest, license, or any other right whatsoever to use the GeoSouthern Marks, except as
set forth in this Section 6.9. Buyer shall, as promptly as practicable, and in any event within six (6) months after the Closing, (a) cause all of the Organizational Documents of the Companies to be amended to eliminate the
word “GeoSouthern” and any word or expression confusingly similar thereto or constituting an abbreviation thereof from the names of such entities; (b) cause such amendments to the Organizational Documents of each Company to be filed,
as appropriate or necessary, with all applicable Governmental Authorities to reflect the elimination of such words and the change of such names; (c) cause the removal of all trademarks, trade names, logos and symbols related to Seller and its
Affiliates from all Company Assets (including all signs); and (d) take all other actions necessary to accomplish the foregoing matters, including any notifications, filings or other actions required by any Governmental Authority. Buyer agrees
never to challenge Seller’s (or its Affiliates’) ownership of the GeoSouthern Marks or any application for registration thereof or any registration thereof or any rights of Seller or its Affiliates therein as a result, directly or
indirectly, of its ownership of the Companies. Except as set forth in this Section 6.9, (i) Buyer will not do any business or offer any goods or services under or using the GeoSouthern Marks; (ii) Buyer will not send, or cause
to be sent, any correspondence or other materials to any Person on any stationery that contains any GeoSouthern Marks which would reasonably be expected to confuse any Person into believing that Buyer has any right, title, interest or license to use
the GeoSouthern Marks; and (iii) Buyer will not otherwise operate the Companies in any manner which would reasonably be expected to confuse any Person into believing that Buyer has any right, title, interest, or license to use the GeoSouthern
Marks.

 6.10 Intellectual Property Transfer; Seller IP License. 

(a) At or prior to the Closing, Seller and its Affiliates (other than the Companies) shall assign, transfer and convey to the Companies all
right, title and interest they may have to Intellectual Property used solely and exclusively by or for the Companies, if any; provided, however, that if any such transfer of any seismic or similar data would require the payment of any
fee to any Third Party, Seller and its Affiliates shall not be required to transfer such data unless and until Buyer or a Company pays such fee. For clarity, Seller and its Affiliates (other than the Companies) shall retain no right, title or
interest (including any express or implied licenses) to any of the foregoing Intellectual Property, and shall purge any copies thereof once Buyer has confirmed that it has complete and accurate copies thereof. 

(b) From and after the Closing, Seller and its Affiliates (other than the Companies) hereby grant to the Companies a non-exclusive, perpetual,
irrevocable, royalty-free, fully paid-up right and license to make, use, reproduce, display, perform, distribute and modify the Seller IP, if any, solely for use in the business of the Companies. The Companies may permit their respective Affiliates,
suppliers, contractors, service providers and consultants to exercise any or all of the foregoing rights and licenses solely at the direction of, and on behalf of, the Companies. The rights granted pursuant to this Section 6.10(b) are
collectively referred to herein as the “Seller IP License”. The Seller IP License shall be binding on assignees and transferees of the Seller IP, and the Seller IP License shall be transferrable to any Third Party that acquires all
or a majority of the business of the Companies. 
 6.11 Insurance. Buyer acknowledges and agrees that, effective upon the Closing,
the insurance policies of Seller and its Affiliates related to the Companies shall be terminated or modified to exclude coverage of the Companies, and, as a result, it shall be the obligation of Buyer to obtain at its sole cost and expense
replacement insurance effective from and after the Closing. Seller shall pursue, and shall cause its Affiliates (including the Companies) to pursue, on behalf of and for the benefit of the Companies, any recovery under any such insurance policy with
respect to any event or occurrence during the Interim Period, and any such recovery shall increase the Interim Revenue Amount; provided that if such recovery occurs subsequent to the Closing, Seller shall pay to Buyer the amount of such
recovery upon receipt thereof by Seller or one of its Affiliates. 
 6.12 Company Indebtedness. In connection with the Closing,
Seller shall use its reasonable best efforts to obtain a release of Liens in respect of the Company Assets under the Credit Agreement and a release of the Companies as borrowers thereunder (the “Release Letters”). The Release
Letters shall (i) indicate the total amount required to be paid to fully satisfy all principal, interest, prepayment premiums, penalties, breakage costs or similar obligations (other than Ordinary Course and contingent indemnification
obligations) related to the Company Indebtedness (the “Payoff Amount”), (ii) state that all Liens in connection therewith relating to the Company Assets shall be, upon the payment of the Payoff Amount on the Closing Date,
released and (iii) authorize the Companies to file UCC-3 termination statements and mortgage releases in all applicable jurisdictions to evidence the release of the Company Indebtedness. Seller and the Companies shall deliver all Notices and
take all other actions necessary to facilitate the termination of the obligations and commitments of the Companies under the Company Indebtedness, the repayment in full of all obligations then outstanding thereunder, the elimination of the Companies
from all agreements related thereto and the release of all Liens applicable to the Company Assets in connection therewith, in each case, on the Closing Date. 

  
 58 

 6.13 Further Assurances. Subject to the terms and conditions of this Agreement, each Party
will use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary or desirable, under applicable Law or otherwise, to consummate the transactions contemplated by this Agreement. The
Parties agree to, and Seller, prior to the Closing, and Buyer, after the Closing, agree to cause the Companies to, execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be
necessary in order to consummate or implement expeditiously the transactions contemplated by this Agreement in accordance with the terms hereof. 

6.14 Publicity. All press releases or other public communications of any nature whatsoever relating to the transactions contemplated by
this Agreement, and the method of the release for publication thereof, shall be subject to the prior written consent of Buyer and Seller; provided, however, that nothing herein shall prevent a Party from publishing such press releases
or other public communications as is necessary to satisfy such Party’s obligations at Law or under the rules of any stock or commodities exchange after consultation with the other Party. Notwithstanding the foregoing, the Parties acknowledge
and agree that Blackstone may provide general information about the subject matter of this Agreement in connection with their customary fund raising, marketing, informational or reporting activities. 

6.15 Fees and Expenses; Transfer Taxes. 

(a) Except as otherwise provided in this Agreement, all fees and expenses, including fees and expenses of counsel, financial advisors, and
accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such fee or expense. 

(b) Seller and Buyer shall each be responsible for and shall indemnify and hold harmless the other Party against fifty percent (50%) of
any state or local transfer, sales (including bulk sales), use, filing, value added, documentary, stamp, gross receipts, registration, conveyance, excise, recording, licensing, stock transfer stamps or other similar Taxes and fees (the
“Transfer Taxes”) arising out of or in connection with or attributable to the transactions contemplated by this Agreement. All Tax Returns with respect to Transfer Taxes incurred in connection with this Agreement or otherwise in
connection with the transactions contemplated hereunder shall be timely filed by the Party responsible for such filing under applicable law. Buyer and Seller shall reasonably cooperate to reduce or eliminate any Transfer Taxes to the extent
permitted by applicable Law. 
 (c) To the extent that the transactions contemplated under this Agreement are determined to involve a
transfer of tangible personal property, Buyer and Seller acknowledge and agree that such transactions constitute a sale of an identifiable segment of a business for purposes of Section 151.304 of the Texas Tax Code. 

  
 59 

 6.16 Like-Kind Exchange. Each of Seller and Buyer 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 Section 1.1031(k)-1(g)(4)(iii) of the Treasury Regulations) or an Exchange Accommodation Titleholder (as that term
is defined in Rev. Proc. 2000-37, 2000-2 C.B. 308) in order to accomplish the transaction in a manner that will comply, either in whole or in part, with the requirements of a like-kind exchange pursuant to Section 1031 of the Code;
provided that (A) the Closing shall not be delayed or affected by reason of such like-kind exchange or any actions taken by either Seller or Buyer in connection with this Section 6.16, (B) an assignment under this
Section 6.16 shall not release any Party from its liabilities and obligations under this Agreement nor shall the consummation or accomplishment of such like-kind exchange be a condition to the Parties’ obligations under this
Agreement; (C) the non-assigning Party’s rights under this Agreement shall not be altered or diminished in any manner; (D) the assigning Party shall indemnify, defend, and hold the Party that is not assigning harmless from all claims,
damages, liabilities, costs and expenses (including, but not limited to reasonable legal fees and any additional Taxes, including Transfer Taxes) in connection with such like-kind exchange; (E) neither Party represents to the other that any
particular tax treatment will be given to either Party as a result of any such assignment and (F) any such Qualified Intermediary or Exchange Accommodation Titleholder to which Buyer assigns all or a portion of its rights pursuant to this
Section 6.16 shall be a corporation or limited liability company, in either case formed in a jurisdiction other than Texas. In the event either Party assigns its rights under this Agreement pursuant to this Section 6.16, such
Party agrees to notify the other Party in writing of such assignment at or before Closing. If Seller assigns its rights under this Agreement for this purpose, Buyer agrees to (i) consent to Seller’s assignment of its rights in this
Agreement in the form reasonably requested by the Qualified Intermediary, and (ii) pay all or a portion of the Adjusted Purchase Price and any adjustments thereto into a qualified escrow or qualified trust account at Closing as directed in
writing. If Buyer assigns its rights under this Agreement for this purpose, Seller agrees to (i) consent to Buyer’s assignment of its rights in this Agreement in the form reasonably requested by Buyer’s Qualified Intermediary or
Exchange Accommodation Titleholder (but in no event will Seller be required to transfer the Company Assets in any form other than through a transfer of the Interests and in no event will Seller be required to transfer Interests in any Company to
more than one transferee, i.e. all of the Interests in any Company will be transferred to a single transferee), (ii) accept all or a portion of the payments payable under this Agreement from the account designated by Buyer’s Qualified
Intermediary or Exchange Accommodation Titleholder at Closing, and (iii) at Closing, subject to the limitations otherwise set forth herein, convey and assign directly to Buyer’s assignee under Section 6.31, Buyer’s
Qualified Intermediary or Buyer’s Exchange Accommodation Titleholder (as directed in writing) the Interests which are the subject of this Agreement upon satisfaction of the other conditions to Closing and other terms and conditions hereof. 

6.17 Non-Solicitation. 

(a) Buyer covenants and agrees that for a period of twelve (12) months following the Closing, neither it nor any of its Affiliates
(including the Companies) will, directly or indirectly, without the prior written consent of Seller, (i) solicit, recruit or employ any employee, officer or director, other than the Continued Employees, of Seller or its Affiliates or
(ii) induce or otherwise counsel, advise or encourage any employee, officer or director of Seller or its Affiliates to leave the employment of Seller and its Affiliates; provided, that this Section 6.17(a) shall not preclude
the hiring of any employee who has been terminated by Seller or its Affiliates at least six (6) months prior to the commencement of employment discussions between Buyer (or its applicable Affiliates) and such employee. 

  
 60 

 (b) Seller covenants and agrees that for a period of twelve (12) months following the
Closing, neither it nor any of its Affiliates will, directly or indirectly, without the prior written consent of Seller, (i) solicit, recruit or employ any Continued Employee or (ii) induce or otherwise counsel, advise or encourage any
Continued Employee to leave the employment of Seller and its Affiliates (including the Companies); provided, that this Section 6.17(b) shall not preclude the hiring of any employee who has been terminated by Buyer or its
Affiliates (including the Companies) at least three (3) months prior to the commencement of employment discussions between Seller (or its applicable Affiliates) and such employee. 

6.18 No Shop. Seller shall not, and shall cause its Affiliates (including the Companies) and each of their respective officers,
directors, employees not to, and direct each of their third-party Representatives not to on its behalf, directly or indirectly, solicit, initiate or encourage any inquiries or proposals from, participate in discussions or negotiations with, or
provide any information to, any Person or group (other than Buyer and its Representatives and Affiliates) relating to any transaction involving the sale of the Interests or all or any part of the Company Assets, or any merger, consolidation,
business combination or similar transaction involving the Companies, the Company Assets or all or substantially all of any part of their business. Seller shall immediately notify Buyer of the existence of any proposal or inquiry received by
GeoSouthern, Seller or any of their respective Affiliates (including any Company) or Representatives, and shall immediately communicate to Buyer the terms of any proposal or inquiry which any of them may receive, including the identity of the Party
making such proposal or inquiry. 
 6.19 Non-Competition. 

(a) Subject to Section 6.19(b), from the date hereof until [omitted], neither GeoSouthern, Seller nor any of their
respective Affiliates shall acquire any Working Interests or other similar rights to extract Hydrocarbons, or make any investments in any Person that owns, directly or indirectly, any such Working Interests or other rights to extract Hydrocarbons in
each case located in any county in which the Leases are located, other than with respect to the Excluded Assets; provided that, nothing in this Section 6.19 shall (i) [omitted] or (ii) restrict any Person from
(A) acquiring surface leases or rights, or (B) acquiring mineral interests that are not severed from the surface estate. 
 (b)
From the date hereof until [omitted], if GeoSouthern, Seller or any of their respective Affiliates [omitted] (the “ROFO Counterparty”) acquires, as permitted by Section 6.19(a)(ii)(B), any mineral interest
in DeWitt or Lavaca Counties that is not severed from the surface estate, then prior to Transferring any interest (the “ROFO Interest”) in such acquired mineral interest to any Person, the ROFO Counterparty shall provide notice to
Buyer (each a “ROFO Notice”) of the proposed Transfer, which ROFO Notice shall include a description of the ROFO Interest and the terms on which the ROFO Counterparty would be willing to Transfer the ROFO Interest to Buyer. On or
before the twentieth (20th) day after receipt of a ROFO Notice, Buyer may elect, by delivering notice to the ROFO Counterparty, to acquire all but not less than all of the ROFO Interest on the terms set forth in the ROFO Notice.

 61 

 
If, within such twenty (20)-day period, Buyer either (i) affirmatively elects, by notice to the ROFO Counterparty, not to exercise its right to acquire the ROFO Interest, or (ii) does
not respond to the ROFO Notice, the ROFO Counterparty may Transfer the ROFO Interest to a Third Party on terms no less favorable in the aggregate to the transferee than those set forth in the ROFO Notice; provided, that if no such Transfer to
a Third Party occurs on or before the one hundred twentieth (120th) day following the earlier of (i) the expiration of such twenty (20)-day period, and (ii) the ROFO Counterparty’s receipt of notice from Buyer affirmatively
electing not to acquire the ROFO Interest, then, prior to Transferring any interest in the ROFO Interest, the ROFO Counterparty must comply again with the provisions of this Section 6.19(b). The restrictions in this
Section 6.19(b) shall not apply to (i) any Transfer of any ROFO Interest to any Affiliate of GeoSouthern (a “Transferee Affiliate”); provided, that (x) such Transfer is not part of a plan to sell,
transfer or assign, directly or indirectly, such ROFO Interest or any direct or indirect interest therein to any Person that is not an Affiliate of GeoSouthern (such as through the sale or issuance of equity interests in an Affiliate that holds such
ROFO Interest), and (y) prior to engaging in any transaction or series of related transactions that would reduce GeoSouthern’s direct or indirect beneficial ownership interest in such Affiliate, GeoSouthern shall cause such Transferee
Affiliate to Transfer such ROFO Interest to GeoSouthern or (ii) any sale of GeoSouthern or all or substantially all of the assets of GeoSouthern. GeoSouthern and Seller shall, and shall cause their Affiliates to, comply with the provisions of
this Section 6.19. [omitted] 
 (c) Each of GeoSouthern and Seller, for itself and on behalf of its Affiliates,
acknowledges and agrees that the restrictions set forth in this Section 6.19 are reasonably designed to protect Buyer’s substantial investment and are reasonable with respect to duration, geographical area and scope and do not
impose undue hardship on GeoSouthern, Seller or any of their Affiliates. If the final judgment of a court of competent jurisdiction declares that any term or provision of this Section 6.19 is invalid or unenforceable, the Parties agree
that the court making the determination of invalidity or unenforceability shall have the power to reduce the duration, geographical area or scope of such term or provision such that the term or provision is invalid and enforceable and comes closest
to expressing the intention of the invalid or unenforceable term or provision. 
 6.20 Debt Financing. Prior to the Closing Date,
Seller shall provide, and shall cause its Affiliates (including the Companies) to provide, and shall use its reasonable best efforts to cause its Representatives and Representatives of its Affiliates (including the Companies) to provide, all
cooperation reasonably requested from time to time by Buyer in connection with any debt financing pursued by Buyer in connection with the transactions contemplated hereby (the “Debt Financing”), including (i) using its

are used solely in connection with a description of the Companies, their business and products or the transactions contemplated hereby. Notwithstanding anything to the contrary contained herein,
any failure by Seller or its Affiliates to perform the obligations set forth in this Section 6.20 shall in no event cause the failure of any condition set forth in Article 8 and Seller shall have no liability to Buyer in respect
thereof. 
 6.21 Litigation Notification. Seller shall promptly notify Buyer if any Company becomes subject to an Order issued, made,
rendered or entered after the date hereof, becomes a party to a Proceeding after the date hereof, or is threatened in writing after the date hereof with any Proceeding.

promptly (and in any event within 24 hours after receipt of such proposal) and (ii) make a timely election to participate in such operation unless Seller requests, and Buyer consents in writing to any non-consent election or other election not

Contracts) which is necessary for the continued operation of the Company Assets immediately after Closing. At or prior to the Closing, Seller shall or shall cause its Affiliates to use their reasonable best efforts to transfer and assign to the
Companies all Contracts listed in the Contract List, Permits and other assets necessary for the continued operation of the Company Assets immediately after Closing, to the extent assignable or, in the case of Permits, shall reasonably assist Buyer
in obtaining replacement Permits in the name of Buyer, including all Seller Material Contracts, except for assets to be made available pursuant to the Transition Services Agreement, to the extent such agreement is entered into pursuant to
Section 6.27, and except for any Contract which prior to the Closing Buyer instructs Seller in writing not to transfer and assign to a Company. 

6.24 Intercompany Accounts. Prior to the Closing, Seller, and after the Closing, Seller and Buyer, shall cause all intercompany
accounts between any Company, on the one hand, and GeoSouthern or any of its Affiliates (except any Company), on the other hand, to be settled in the Ordinary Course.

necessary to effect the transfer of the employment of those Employees who are employed by GeoSouthern to Management LLC and the contribution of Management LLC to Seller. Not later than three (3) days prior to the Closing Date, Seller shall
update Schedule 4.9(a)(ii), accordingly, in compliance with the provisions of this Agreement. 

  
 63 

 6.26 GeoSouthern. GeoSouthern agrees that (a) during the period from the date hereof
until the Closing Date, GeoSouthern shall cause each of its Affiliates (including Seller and the Companies) to perform or comply with in all material respects all of the covenants and agreements required by this Agreement to be performed or complied
with by Seller and its Affiliates (including the Companies) on or before the Closing and (b) from and after the Closing Date, GeoSouthern shall cause each of the Seller and its Affiliates to perform or comply with in all material respects the
covenants and agreements set forth in Sections 6.3(b), 6.17(b), 6.19, 6.24, 6.25, 6.27 and 6.28. Notwithstanding anything to the contrary contained herein, Buyer expressly agrees that
GeoSouthern’s liability for damages (including damages in lieu of equitable relief pursuant to Section 11.9(a) hereunder is strictly limited to any amounts payable pursuant to Section 10.2(b), and any breach of this
Agreement by GeoSouthern shall be deemed to be a breach by Seller subject to the recourse provisions available to Buyer against Seller; provided, that the foregoing shall not be deemed to limit any recourse Buyer may have against GeoSouthern
under Section 11.9(a). 
 6.27 Transitional Personnel. Seller, GeoSouthern and their respective Affiliates hereby
undertake to make Transitional Personnel available to Buyer during normal business hours on each Business Day for a period of ninety (90) days following the Closing Date, to reasonably assist with, and to respond to, questions about land,
accounting, finance, environmental, legal and regulatory matters in connection with the transition of operations of the Companies to Buyer. In connection with making such Transitional Personnel available, solely to the extent that any individual
member of the Transitional Personnel is required to commit a material portion of his or her daily duties for the benefit of Buyer during such period (such material portion being deemed to be greater than 1 hour per day on average in any two week
period), Buyer shall pay to Seller and its Affiliates such portion of the base salary of such member of the Transitional Personnel as is allocable to the work performed for the benefit of Buyer by such member of the Transitional Personnel (such
allocation being based on the number of hours worked by such member of the Transitional Period as a proportion of a 40 hour work week). If any member of the Transitional Personnel shall leave the employment of Seller and its Affiliates at any time
prior to the 90th day after the Closing, Seller and its Affiliates shall in no event be deemed to have breached this Section 6.27 by reason of such member of the Transitional Personnel no longer being available to Buyer. To the extent
that on or before the date that is 30 days prior to the Closing Date Buyer reasonably determines in good faith that the availability of Transitional Personnel pursuant to this Section 6.27 will not be sufficient to facilitate
Buyer’s transition of the Companies from Seller to Buyer, then Buyer and Seller shall negotiate in good faith to enter into a reasonable transition services agreement (the “Transition Services Agreement”), on customary terms,
which terms shall include customary compensation and indemnification provisions for the benefit of Seller and its Affiliates. 
 6.28

notices, directions and instructions (as are necessary for the Escrow Agent to fulfill its obligations set forth in the Escrow Agreement) in accordance with the provisions of this Agreement.

its right to purchase the Interests), other than rights previously assigned under Section 6.16, to a limited liability company formed under the laws of the State of Oklahoma or the State of Delaware and shall cause such limited liability
company to purchase the Interests and pay the Adjusted Purchase Price (and pay or receive any amounts in respect of adjustments thereto) in accordance with Article 2; provided, that such assignment shall not relieve Buyer from its obligations
under this Agreement. Notwithstanding anything in the foregoing, such assignee limited liability company shall be entitled to the provisions of Section 6.16 as if it were the Buyer, subject to the limitations therein. 

6.32 Leases. Prior to the Closing Date, at Buyer’s request, Seller and its Affiliates and Buyer shall negotiate in good faith
lease agreements, on customary, market terms, with respect to Buyer’s use of such portion of the office space (not to exceed half of the premises) of Seller and its Affiliates in 4060 Wildwood Forest, Spring Texas, as Buyer shall reasonably
require and with respect to Buyer’s use of the Cuero field office space of Seller and its Affiliates. At the Closing, Seller (or the Affiliate of Seller that owns the relevant building) and Buyer shall enter into any such lease agreements.

employment with Buyer and its subsidiaries is terminated on or prior to December 31, 2014 severance payments and benefits that are no less favorable than those that would be paid to a similarly situated employee of Buyer or any of its

employees of Buyer under Buyer’s tuition assistance program as in effect on the date hereof (provided, further, all such Continuing Employees shall be immediately eligible to participate in Buyer’s tuition assistance program
such that there will be no disruption of tuition payment obligations paid, payable or committed to be paid with respect to all such Continuing Employees).

Affiliate of Buyer to the Employees, including vacation plans or arrangements, 401(k) or other retirement plans, and any severance and welfare plans, except to the extent such credit would result in duplication of benefits; provided, that
periods of employment will not be taken into account for the purpose of any entitlement to participate in, or receive or accrue benefits under, any defined benefit pension plans, retiree medical programs or other retiree welfare benefit programs
maintained by Buyer or its Affiliates. 
 (b) Pre-Existing Conditions. Buyer shall use commercially reasonable efforts to
(i) waive any limitation on health insurance coverage of Employees and their eligible dependents due to pre-existing conditions under all applicable medical plans of Buyer or an Affiliate of Buyer to the extent such condition was satisfied or
waived under the comparable Plan prior to the Closing Date and (ii) credit Employees and their eligible dependents with all payments credited against out-of-pocket maximums and deductible payments and co-payments paid by such Person, in each
case, under the comparable Plan prior to the Closing Date during the plan year in which the Closing Date occurs for the purpose of determining the extent to which any such Person has satisfied his or her deductible and whether he or she has reached
the out-of-pocket maximum under any health insurance plans of Buyer or an Affiliate of Buyer for such year. 
 7.3 COBRA and
Post-Employment Welfare Benefits. On and after the Closing Date, Buyer shall, or shall cause its Affiliates to, assume all obligations to provide continuation health care coverage in accordance with COBRA to all Employees and their qualified
beneficiaries with respect to any qualifying events occurring on or following the Closing Date. 
 7.4 Tax Reporting. If applicable,
Buyer and Seller hereby agree to follow the alternative procedure for employment Tax withholding as provided in Rev. Proc. 2004-53, I.R.B. 2004-34. Accordingly, none of Seller or its Affiliates shall have any employment Tax reporting

(ii) require Seller or Buyer to continue any Plan or Employee Plan or prevent the amendment, modification, or termination thereof at any time; (iii) confer upon any employee any rights or remedies under or by reason of this Agreement; or

 70 

 (ii) any inaccuracy or breach of any representation or warranty made by GeoSouthern or Seller in
Article 3 or by Seller in Article 4 as of the Closing Date (other than any inaccuracy or breach of any representation or warranty made in Section 4.11 to the extent relating to any Covered Environmental Matters), each of
which representations and warranties will be deemed for purposes of this Section 10.2(a)(ii) to have been made by GeoSouthern or Seller as of the Closing Date, except that those representations and warranties that are made as of a
specific date will be deemed for purposes of this Section 10.2(a)(ii) to have been made by GeoSouthern or Seller as of such date; or 

(iii) any breach of any covenant, agreement or undertaking made by Seller or GeoSouthern in this Agreement. 

(b) GeoSouthern shall indemnify and hold Buyer and its Affiliates harmless from and against any and all Losses suffered or incurred by Buyer
and its Affiliates arising out of or resulting from (i) any inaccuracy or breach of any representation or warranty set forth in Section 3.2(b) or Section 4.3 or (ii) any inaccuracy or breach of any representation or

or punitive damages resulting from any breach of the representations and warranties of Seller or GeoSouthern set forth in Article 3 or Section 4.3 or otherwise pursuant to this Section 10.2(b) and GeoSouthern’s
obligations under this Section 10.2(b) shall survive until the expiration of the survival period of Sections 3.2(c) and 4.3, except that where any specific claim for indemnification hereunder is delivered to GeoSouthern on
or before the expiration of such survival period, in accordance with the terms hereof, such claim and GeoSouthern’s obligations hereunder with respect thereto shall survive until the resolution of such claim. 

(c) “Losses” means the amount of any actual liability, loss, cost, expense, claim, award or judgment incurred or suffered by
any Indemnified Party arising out of or resulting from the indemnified matter, including reasonable fees and expenses of attorneys, consultants, accountants or other agents and experts reasonably incident to matters indemnified against and the costs

 71 

 (e) The Losses of the Buyer Indemnified Parties described in this Section 10.2 as to
which the Buyer Indemnified Parties are entitled to indemnification hereunder are hereinafter collectively referred to as the “Buyer Losses.”

representation or warranty (other than Section 4.6(i), Section 4.14 or any reference to “Material” in the term “Material Contract”) shall be deemed to exist either if such representation or warranty is
actually inaccurate or breached or would have been inaccurate or breached if such representation or warranty had not contained any limitation or qualification as to materiality or Material Adverse Effect (which instead will be read as any adverse
effect or change), and (ii) the amount of Losses in respect of any breach of a representation or warranty (including any deemed breach resulting from the application of clause (i) but excluding Section 4.6(i) and 4.14 or
any reference to “Material” in the term “Material Contract”) shall be determined without regard to any limitation or qualification as to materiality or Material Adverse Effect (which instead will be read as any adverse effect or
change) set forth in such representation or warranty. 
 10.3 Indemnification Obligations of Buyer. 

(a) Subject to the other terms of this Article 10, from and after the Closing Date, Buyer shall indemnify, defend and hold harmless
Seller and its Affiliates (collectively, the “Seller Indemnified Parties”) from, against and in respect of any and all Losses arising out of or resulting from: 

(i) any breach of any representation or warranty made by Buyer in Article 5 or in the certificate delivered by Buyer pursuant to
Section 2.5(d)(i); 
 (ii) any breach of any covenant, agreement or undertaking made by Buyer in this Agreement; and 

(iii) any liabilities or obligations that arise after the Closing Date under any Contract or Permit transferred to a Company pursuant to
Section 6.23, provided, that, with respect to any such Contract, such Contract was provided to Buyer prior to the date of this Agreement. 

(b) The Losses of Seller Indemnified Parties described in this Section 10.3 as to which the Seller Indemnified Parties are
entitled to indemnification hereunder are hereinafter collectively referred to as “Seller Losses.” 
 10.4
Indemnification Procedure. 
 (a) Promptly after receipt by a Buyer Indemnified Party or a Seller Indemnified Party (hereinafter
collectively referred to as an “Indemnified Party”) of notice by a Third Party (including any Governmental Authority) of any Proceeding or the commencement of any audit with respect to which such Indemnified Party may be entitled to
receive payment hereunder for any Buyer Losses or any Seller Losses (as the case may be), such Indemnified Party will notify Buyer or Seller, as the case may be (in such capacity, Buyer or Seller is hereinafter referred to as an
“Indemnifying Party”) of such Proceeding or audit; provided, 

  
 72 

 
however, that the failure to so notify the Indemnifying Party will relieve the Indemnifying Party from liability under this Agreement with respect to such Proceeding or audit only if, and
only to the extent that, the defense of such Proceedings or audit is prejudiced as a result of the failure to notify the Indemnifying Party. The Indemnifying Party will have the right, at its sole expense, upon written notice delivered to the
Indemnified Party within fifteen (15) days after receiving such notice, to assume the defense of such Proceeding with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party. In the event, however, that
the Indemnifying Party declines or fails to (i) assume the defense of the Proceeding on the terms provided above or to prosecute such defense in good faith or (ii) employ counsel reasonably satisfactory to the Indemnified Party, in any
case within such fifteen (15) day period, then such Indemnified Party may employ counsel to represent or defend it in any such Proceeding and the Indemnifying Party will (subject to the other terms and provisions of this Agreement) pay the
reasonable fees and disbursements of such counsel as incurred. In any Proceeding with respect to which indemnification is being sought hereunder, the Indemnified Party or the Indemnifying Party, whichever is not assuming the defense of such
Proceeding, will have the right to participate in such matter and to retain its own counsel at such Party’s own expense. The Indemnifying Party or the Indemnified Party, as the case may be, will at all times use reasonable best efforts to
(x) diligently conduct the defense of any Proceeding for which it is maintaining the defense, (y) keep the Indemnified Party or the Indemnifying Party, as the case may be, reasonably apprised of the status of the defense of any Proceeding
the defense of which they are maintaining and (z) cooperate in good faith with each other with respect to the defense of any such Proceeding. 

(b) No Indemnified Party may settle or compromise any Proceeding or consent to the entry of any judgment with respect to which indemnification
is being sought hereunder without the prior written consent of the Indemnifying Party, unless such settlement, compromise or consent (i) includes an unconditional release of the Indemnifying Party from all liability arising out of such
Proceeding, (ii) does not contain any admission or statement of any wrongdoing or liability on behalf of the Indemnifying Party and (iii) does not contain any equitable order, judgment or term that in any manner affects, restrains or
interferes with the business of the Indemnifying Party or any of the Indemnifying Party’s Affiliates. An Indemnifying Party may not settle or compromise any Proceeding or consent to the entry of any judgment with respect to which
indemnification is being sought hereunder, without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed. 

(c) A claim for indemnification by an Indemnified Party for any matter not involving an Proceeding by a Third Party may be asserted by Buyer
(on behalf of the Buyer Indemnified Parties) or Seller (on behalf of the Seller Indemnified Parties), as applicable, by written notice to the Indemnifying Party from whom indemnification is sought. Such notice will specify with reasonable
specificity the basis for such claim. 
 10.5 Limits of Liability. Notwithstanding anything to the contrary set forth herein, Buyer
Indemnified Parties shall not be entitled to recover on a claim for indemnification under Section 10.2(a)(i) or (ii) for any individual Buyer Loss or series of related Buyer Losses unless the amount of such Buyer Loss or
series of related Buyer Losses exceeds [omitted]; provided, however, that the foregoing limitation shall not apply to any claim for indemnification with respect to any inaccuracy or breach (or deemed inaccuracy or breach) of the
representations and warranties set forth in Sections 3.1(a) (Organization of Seller); 3.2(b) (Ownership of Interests); 4.1 (Organization); and 4.3 (Capitalization).

 10.6 Sole and Exclusive Remedy. 

(a) From and after the Closing, the remedies set forth in this Article 10 shall, in the absence of fraud or intentional
misrepresentation, provide the sole and exclusive remedies arising out of, in connection with, relating to or arising under this Agreement, any document, agreement, certificate (including the certificates delivered at Closing by Buyer and Seller
pursuant to Section 2.5(c)(iii) and Section 2.5(d)(i), respectively) or other instrument delivered pursuant hereto or the transactions contemplated hereby, whether based on contract, tort, strict liability, other laws or
otherwise, including any breach or alleged breach of any representation, warranty, covenant or agreement made herein or any other document contemplated herein or delivered pursuant hereto. The Parties acknowledge and agree that, in the absence of
fraud or intentional misrepresentation, from and after the Closing the remedies available in this Article 10 supersede (and each Party waives and releases) any other remedies available at Law or in equity against the other Parties including
rights of rescission, rights of contribution and claims arising under applicable statutes. 
 (b) Buyer, on behalf of itself and all other
Buyer Indemnified Parties, further acknowledges and agrees that, after the Closing, in the absence of fraud or intentional misrepresentation, the Holdback Amount then held in escrow pursuant to the Escrow Agreement shall be the sole and exclusive
source for satisfaction of any claims arising from the transaction contemplated hereby other than a claim against GeoSouthern pursuant to Section 10.2(b). 

10.7 Compliance with Express Negligence Rule. ALL RELEASES, LIMITATIONS ON LIABILITY AND INDEMNITIES CONTAINED IN THIS AGREEMENT,
INCLUDING THOSE IN THIS ARTICLE 10, SHALL APPLY IN THE EVENT OF THE SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF THE PARTY WHOSE LIABILITY IS RELEASED, DISCLAIMED, LIMITED OR INDEMNIFIED. 

10.8 Insurance Proceeds. The Buyer Losses and Seller Losses giving rise to any claim hereunder shall be reduced by any insurance
proceeds or other payments actually received by the Indemnified Party (less the amount of any deductible paid or costs incurred by such Indemnified Party in connection therewith) in satisfaction of any Losses giving rise to the claim. Buyer shall
use its reasonable best efforts to recover under insurance policies or under other rights of recovery for Losses; provided, however, that Buyer shall be entitled to seek payment (including indemnification) under this Agreement pending
resolution of any such recovery efforts. 
 10.9 Tax Treatment of Indemnity Payments. For federal income tax purposes, the Parties
agree to treat (and shall cause each of their respective Affiliates to treat) any indemnity payment under this Agreement as an adjustment to the Adjusted Purchase Price payable to Seller pursuant to Section 2.2 hereof unless a final and
non-appealable determination by an appropriate Governmental Authority (which shall include the execution of an IRS Form 870-AD or successor form) provides otherwise. 

  
 74 

 10.10 Damages Waiver. No Indemnifying Party shall have any liability to any Indemnified
Party for consequential, indirect, exemplary or punitive damages, except to the extent of reimbursement of such damages actually recovered by a Third Party from such Indemnified Party.

11.2 Assignment. Neither Party shall assign this Agreement or any part hereof without the prior written consent of the other Party.
Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns. 

11.3 Rights of Third Parties. Other than any rights or remedies provided to the Financing Sources in Sections 11.9(b) and
11.10(e) hereof, nothing expressed or implied in this Agreement is intended or shall be construed to confer upon or give any Person, other than the Parties, any right or remedies under or by reason of this Agreement. 

11.4 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. Any facsimile copies hereof or signature hereon shall, for all purposes, be deemed originals. 

11.5 Entire Agreement. This Agreement (together with the Disclosure Schedule and exhibits to this Agreement) and the Confidentiality
Agreement constitute the entire agreement among the Parties and supersede any other agreements, whether written or oral, that may have been made or entered into by or among any of the Parties or any of their respective Affiliates relating to the
transactions contemplated hereby; provided that, in the event of a conflict between the terms of the Confidentiality Agreement and Section 6.17(a), the terms of this Agreement set forth in Section 6.17(a) shall govern
and prevail with respect to such conflict. 
 11.6 Disclosure Schedule. Unless the context otherwise requires, all capitalized terms
used in the Disclosure Schedule shall have the respective meanings assigned in this Agreement. No reference to or disclosure of any item or other matter in the Disclosure Schedule shall be construed as an admission or indication that such item or
other matter is material or that such item or other matter is required to be referred to or disclosed in the Disclosure Schedule. No disclosure in the Disclosure Schedule relating to any possible breach or violation of any agreement or Law shall be
construed as an admission or indication that any such breach or violation exists or has actually occurred. The inclusion of any information in the Disclosure Schedule shall not be deemed to be an admission or acknowledgment by Seller, in and of
itself, that such information is material to or outside the Ordinary Course of any Company or required to be disclosed on the Disclosure Schedule. Each disclosure in the Disclosure Schedule shall be deemed to qualify the particular sections or
subsections of the representations and warranties expressly referenced, and each other section or subsection of the representations and warranties where the relevance of such disclosure is reasonably apparent on its face; provided,
however, that (i) no disclosure shall be deemed to qualify Sections 3.1(c), 3.2(b), 4.2 (other than a cross-reference to Section 3.1(c)), 4.3 or 5.3 unless expressly set forth on the
relevant Schedule and (ii) no disclosure expressly referencing Section 4.6 shall be deemed to qualify any other section of the representations and warranties, except to the extent of any specific cross reference. 

  
 76 

 11.7 Amendments. This Agreement may be amended or modified in whole or in part, and terms
and conditions may be waived, only by a duly authorized agreement in writing which makes reference to this Agreement executed by each Party. 

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

11.9 Specific Performance; Waiver of Claims Against Financing Sources 

(a) The Parties acknowledge and agree (i) that each Party would be irreparably harmed by a breach by the other Party of any of such other
Party’s obligations under this Agreement and that the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise
breached and (ii) that the non-breaching Party shall be entitled to injunctive relief, specific performance, and other equitable remedies against the breaching Party to enforce the performance by the breaching Party of its obligations under
this Agreement (this being in addition to any other remedy to which the non-breaching Party may be entitled at law or in equity), and the Parties hereby consent and agree to such injunctive relief, specific performance, and other equitable remedies.
Accordingly, each Party waives (a) any defenses in any action for specific performance pursuant to this Agreement that a remedy at law would be adequate and (b) any requirement under any Law to post a bond or other security as a
prerequisite to obtaining equitable relief. 
 (b) None of the Financing Sources will have any liability to the Seller, the Companies or
their respective Affiliates relating to or arising out of this Agreement, the Debt Financing or otherwise, whether at law, or equity, in contract, in tort or otherwise, and neither the Seller, the Companies nor any of their respective Affiliates
will have any rights or claims against any of the Financing Sources hereunder or thereunder. In no event shall the Seller nor the Companies be entitled to seek the remedy of specific performance of this Agreement against the Financing Sources. 

11.10 Governing Law; Jurisdiction. 

(a) Law. This Agreement shall be governed and construed in accordance with the Laws of the State of Texas, without regard to the Laws
that might be applicable under conflicts of laws principles. 

  
 77 

 (b) Forum. The Parties agree that the appropriate, exclusive and convenient forum for any
disputes between any of the Parties hereto arising out of this Agreement or the transactions contemplated hereby shall be in any state or federal court in Harris County, Texas, and each of the Parties hereto irrevocably submits to the jurisdiction
of such courts solely in respect of any legal proceeding arising out of or related to this Agreement. The Parties further agree that the Parties shall not bring suit with respect to any disputes arising out of this Agreement or the transactions
contemplated hereby in any court or jurisdiction other than the above specified courts. The Parties further agree, to the extent permitted by Law, that a final and nonappealable judgment against a Party in any action or proceeding contemplated above
shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified or exemplified copy of which shall be conclusive evidence of the fact and amount of such judgment. 

(c) Jurisdiction. To the extent that any Party hereto has or hereafter may acquire any immunity from jurisdiction of any court or from
any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each such Party hereby irrevocably (i) waives such immunity in
respect of its obligations with respect to this Agreement, and (ii) submits to the personal jurisdiction of any court described in Section 11.10(b). 

(d) JURY WAIVER. The Parties hereto agree that they hereby irrevocably waive the right to trial by jury in any action to enforce or
interpret the provisions of this Agreement.

contrary, the Parties hereto acknowledge and irrevocably agree (i) that any Proceeding, whether in law or in equity, whether in contract or in tort or otherwise, in which Seller or its Affiliates is seeking recourse of any nature from the
Financing Sources arising out of, or relating to, the transactions contemplated hereby, the Debt Financing, or the performance of services thereunder or related thereto shall be subject to the exclusive jurisdiction of any state or federal court
sitting in the Borough of Manhattan, New York, New York, and any appellate court thereof and each Party hereto submits for itself and its property with respect to any such Proceeding to the exclusive jurisdiction of such court, (ii) not to
bring or permit any of their Affiliates to bring or support anyone else in bringing any such Proceeding in any other court, (iii) TO WAIVE AND HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN RESPECT OF ANY SUCH PROCEEDING, (iv) that any such
Proceeding shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the conflicts of law rules of such State that would result in the application of the laws of any other State and (v) that
the Financing Sources are express third party beneficiaries of, and may enforce, any provisions in this Agreement reflecting the foregoing agreements. 

11.11 No Recourse. This Agreement may only be enforced against, and any claims or causes of action that may be based upon, arise out of
or relate to this Agreement, or the negotiation, execution or performance of this Agreement may only be made against the entities that are expressly identified as Parties hereto in their capacities as such and, except to the extent otherwise
provided herein, no former, current or future equity holders, controlling persons, directors, officers, employees, agents or Affiliates of any Party hereto or any former, current or 

  
 78 

 
future, direct or indirect, equity holder, controlling person, director, officer, employee, general or limited partner, member, manager, agent or Affiliate of any of the foregoing (each, a

Credit Agreement. This Agreement shall be a Transaction Document for all purposes.
