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

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 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 

  
 19 








 
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

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 (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 

  
 38 








 
(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). 

(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.

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) [omitted] 

(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 

  
 39 








 
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).

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

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

 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.

(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.

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.

 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.

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. 

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, 

  
 45 








 
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

(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

 46

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.

financing pursued by Buyer in connection with the transactions contemplated hereby (the “Debt Financing”), including (i) using its reasonable best efforts to cause its independent accountants to cooperate with and assist Buyer
in preparing customary and appropriate information packages and offering materials as the parties to the Debt Financing may reasonably request for use in connection with the offering and/or syndication of debt securities, loan participations and
other matters contemplated by the Debt Financing, and (ii) furnishing Buyer and the Buyer’s Representatives with financial and other pertinent information regarding the Companies, including with respect to the operations of the Companies,
as may be reasonably requested by Buyer. Seller hereby consents to the use of the logos of the Companies in connection with the syndication and marketing of the Debt Financing; provided that, such logos are used in a manner that is not
intended to harm or disparage the Companies or such logos and 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.

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

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

 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 

  
 48 








 
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 [omitted], 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.

Agreement (including, for the avoidance of doubt, 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

cause one of its subsidiaries to provide: (A) to each Continued Employee whose 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 Affiliates upon a termination of such employee’s employment at such time under such same circumstances; and (B) continued payment of tuition for Continued Employees
and their dependents who, immediately prior to the Closing Date, participate in that certain tuition assistance Employee Plan of GeoSouthern, on terms that are no less favorable than those available to similarly situated employees of Buyer under

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

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

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
responsibilities, and Buyer shall have full employment Tax reporting responsibilities, for the Employees following the close of business on the Closing Date, including in respect of the calendar year in which the Closing Date occurs.

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 (iv) be treated as an amendment to any Plan or

(b) by either Buyer or Seller, upon Notice to the other Party, if the Closing has not been consummated by June 30, 2014, provided,
however, that neither Buyer nor Seller will be entitled to terminate this Agreement pursuant to this Section 9.1(b) if such Person’s breach of any representation, warranty or covenant set forth in this Agreement has been the
cause of the Closing failing to occur by such date; 
 (c) by Buyer, upon Notice to Seller, if there has been a breach by Seller of any
representation, warranty, or covenant contained in this Agreement that would prevent the satisfaction of any condition to the obligations of Buyer set forth in Section 8.1 and, if such breach is of a character that is capable of being
cured, such breach has not been cured by Seller within thirty (30) days after Notice thereof from Buyer; 
 (d) by Seller, upon Notice
to Buyer, if there has been a breach by Buyer of any representation, warranty, or covenant contained in this Agreement that would prevent the satisfaction of any condition to the obligations of Seller set forth in Section 8.2 and, if
such breach is of a character that is capable of being cured, such breach has not been cured by Buyer within thirty (30) days after Notice thereof from Seller; 

(e) [omitted]; or 
 (f)
by either Buyer or Seller, upon Notice to the other Party, if any Governmental Authority having competent jurisdiction has issued a final, non-appealable Order, decree, ruling or injunction (other than a temporary restraining order) or taken any
other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such injunction or other action shall have become final and non-appealable. 

9.2 Effect of Termination. If a Party terminates this Agreement under Section 9.1, then such Party shall promptly give
Notice to the other Party specifying the provision hereof pursuant to which such termination is made, and this Agreement shall become null and void and have no effect, except that the agreements contained in this Article 9, Article 10,
the provisions of Section 6.3, Section 6.14 and Section 6.15 shall survive termination hereof. No termination of this Agreement pursuant to Section 9.1 and nothing contained in this
Section 9.2 shall relieve any Party to this Agreement of liability for willful breach of this Agreement occurring prior to any termination, or for willful breach of any provision of this Agreement that specifically survives termination
hereunder. The Confidentiality Agreement shall not be affected by a termination of this Agreement.

Indemnification 
 10.1
[omitted] 
 10.2 [omitted] 

10.3 [omitted] 
 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, 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. 

  
 55 








 (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 [omitted] 

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 [omitted]. 
 10.7 [omitted] 

  
 56 








 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. 

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 

  
 58 








 
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. 
 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 

  
 59 








 
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. 
 (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.

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 

  
 60 








 
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 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 “Non-Recourse Party”) shall have any liability for any obligations or liabilities of the Parties to this
Agreement or for any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, the transactions contemplated hereby or in respect of any representations made or alleged to be made in connection herewith. Without
limiting the rights of any Party against the other Parties hereto, in no event shall any Party or any of its Affiliates seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages
from, any Non-Recourse Party.
