NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

ARTICLE I.

DEFINITIONS

1.1    Definitions . All capitalized terms not otherwise defined herein shall have the meanings given them in the Transaction Agreements. As used in this Agreement, capitalized terms set forth on Annex A shall have the meanings set forth therein.

ARTICLE II.

POWER AND AUTHORITY; SERVICES

2.1    Service Provider Power and Authority; Services.

(a)    Subject to the direction and control of the Owner Group, the terms and provisions of this Agreement, and the Development Plan and Budget, and subject to the limitations set forth in Section 2.3, Service Provider shall provide the Owner Group with services identical in

1

scope, nature and quality to the services historically provided by Service Provider in connection with its management and operation during the period from January 1, 2016, to the Closing Date of the Assets acquired (directly or indirectly) by the Owner Group pursuant to the Transaction Agreements, including all accounting, financial, managerial, project management, business development, marketing, operational, land, lease maintenance, regulatory, environmental, geological and geophysical, engineering, tax, information technology and other day-to-day services reasonably necessary to operate the business of the Owner Group in relation to the Assets, including the services more particularly described on Exhibit A attached hereto, but in each case excluding the Excluded Services (the “Services”). The Service Provider shall perform the Services in consideration for the Services Fee at the Service Provider’s cost; provided, however, that Service Provider will not be responsible for Owner Group Costs, and, notwithstanding anything to the contrary, nothing shall require Service Provider to advance its own funds for Owner Group Costs.

(b)    As part of the Services, Service Provider will use its commercially reasonable efforts to propose, conduct and complete all operations and activities contemplated by the Development Plan and Budget at the times contemplated by the Development Plan and Budget. Service Provider shall promptly notify the Owner Group in writing if at any time Service Provider reasonably expects to exceed the aggregate amount set forth in the Development Plan and Budget for any category of expenses. Notwithstanding anything in this Agreement to the contrary (other than Section 2.2), in no event shall Service Provider incur any costs or expenses for the account of Owner or reimbursable by Owner in an amount greater than 10% in excess of the aggregate amount set forth in the Development Plan and Budget for any category of expenses without the prior written consent of Owner.

(c)    Owner shall have the right from time to time to elect to cease having Service Provider provide any of the Services and to provide such Services itself or by another service provider, and upon request from Owner, Service Provider will reasonably cooperate with Owner in the transition of such Services to the Owner Group or a new service provider specified by Owner. For the avoidance of doubt any such election shall not result in a reduction of the Services Fee.

(d)    The Service Provider shall be entitled during the Term and any Transition Services Period to utilize solely in connection with the performance of the Services those offices, buildings, yards, and other sites and those vehicles and such other tools and equipment as were acquired by Owner Group pursuant to the Transaction Agreements that were utilized historically prior to the Closing Date in relation to the Assets by field-level employees of the Service Provider (the “Field Facilities and Equipment”). Service Provider shall not pay any rent, fee or other cost for its use of the Field Facilities and Equipment. Service Provider shall return the Field Facilities and Equipment to the Owner Group at the end of the Term and any Transition Services Period in the same condition as on the Closing Date, ordinary wear and tear excepted.

(e)    If at any time Service Provider fails or is unable to perform any of the Services, and such failure or inability is not cured within thirty (30) days after delivery by Owner to Service Provider of written notice of such failure or inability, Owner Group shall use commercially reasonable efforts to obtain reasonable replacement services therefor. In such event, Owner Group shall have the right to deduct the amount of costs so incurred by Owner Group from

2

its payments of the Monthly Services Fee; provided, however, pursuant to the dispute resolution procedures set forth in Section 10.18, Service Provider may dispute that it has failed, or is unable, to perform any of the Services, in which case there shall be no deduction from the Services Fee until such time as there has been a final determination that Service Provider has failed, or is unable, to perform those Services which Owner alleges that Service Provider has failed, or is unable, to perform. If it is ultimately determined that Service Provider has in fact failed or been unable to perform any of the Services for which Owner Group has obtained reasonable replacement services and has incurred costs which were not deducted because of the operation of this Section 2.1(e), Service Provider will reimburse Owner Group for such costs. The Service Provider’s obligations to make such reimbursement shall survive the end of the Term and the Transition Services Period until any such dispute is resolved and any reimbursement owned to Owner Group has been paid.

(f)    The Owner Group will be responsible for the following, at its own expense (the “Excluded Services”):

2.2    Emergency. In the event of an imminent emergency relating to the Assets (“Emergency”), while acting as a Reasonable and Prudent Service Provider, Service Provider shall, without any prior notice to, or approval from, the Owner Group, take all customary measures consistent with the standards set forth in Section 2.10 for the protection of life, health, the environment and property. In such event, Service Provider shall use commercially reasonable

3

efforts to notify the Owner Group of the existence or occurrence of such an imminent Emergency as soon as reasonably possible after the Emergency occurs, but in any event within twenty four (24) hours of its being put on notice of an imminent Emergency, setting forth the nature of the imminent Emergency, the corrective action taken or proposed to be taken, and the actual or estimated cost and expense associated with such corrective action.

2.3    Limitations on Service Provider’s Authority. Notwithstanding anything herein to the contrary, without the prior written consent of the Owner Group, Service Provider shall not take any action set forth on Exhibit B. The Owner Group may at any time amend Exhibit B by providing written notice to Service Provider, which notice shall include an amended Exhibit B reflecting such amendment. Any such amendment shall be effective upon Service Provider’s receipt of such written notice.

2.4    Ownership of Property.

(a)    Without limitation to Service Provider’s (or any Affiliate of Service Provider’s) rights and remedies under any Operating Agreement, the Parties agree and acknowledge that neither Service Provider nor any Affiliate of Service Provider shall, by virtue of its role as “Service Provider” hereunder or as a result of the terms of this Agreement, have, or be deemed to have, any direct ownership interest in the Assets (or in any of the equipment, materials or other property related thereto and purchased by the Owner Group directly or by Service Provider on behalf of Owner Group).

(b)    All of the assets and properties owned, purchased, leased, developed, constructed and otherwise acquired or entered into in connection with the performance of the Services pursuant to this Agreement (including (i) all Assets and all ▇▇▇▇▇, equipment, machinery, materials, supplies, inventory, other personal property and other assets and properties owned, leased or otherwise acquired in connection therewith, (ii) rights-of-way, Applicable Contracts, and any and all reports, records, statements and information prepared or caused to be prepared by Service Provider in connection with this Agreement, and (iii ) all proceeds, cash and funds generated or attributable to the Assets) shall be and remain the sole property of the Owner Group. If, at any time during the term of this Agreement, any such assets or properties are held in the name of Service Provider or its Affiliates, Service Provider will (and will cause its Affiliates to) promptly convey such assets and properties to the Owner Group.

2.5    Service Provider’s Delegation of Authority.

(a)    Service Provider shall be permitted to use Affiliates of Service Provider and the officers and employees of any of its Affiliates in order to perform the Services. Service Provider may not delegate any authority, power, or right that could not be exercised directly by Service Provider under this Agreement.

(b)    If any Person other than Service Provider is used to perform any of the Services (or any part of the Services), the performance by such Person of such Services shall be treated hereunder as if Service Provider performed such Services itself, and if the costs of such performance by Service Provider would have been borne by the Service Provider under the provisions of this Agreement, then the costs of such performance by such Person shall be borne

4

by Service Provider and shall not result in incremental costs to the Owner Group. Service Provider shall not change any material corporate-level or back-office third-party service provider without the consent of Owner. Service Provider agrees that upon written notice (stating adequate cause related to inadequate performance or cost issues) provided by Owner after consultation with Service Provider, Service Provider shall use commercially reasonable efforts to replace any third-party service provider identified by the Owner Group to cease performing the Services on behalf of Service Provider

2.6    Key Persons; Dedicated Employees; Shared Employees.

(a)    At all times, at Service Provider’s sole cost and expense, Service Provider shall retain and have available to it a professional staff and outside consultants and contractors which together shall be reasonably adequate in size, experience and competency to discharge properly the duties and functions of Service Provider hereunder. Service Provider shall devote personnel and time and grant access to such assets and buildings of Service Provider as are necessary to provide the Services consistent with the standards set forth in this Agreement.

(b)    Service Provider shall cause the Key Persons who are not Dedicated Employees to devote a substantial amount of their professional time and efforts to providing the Services, and in any event to spend sufficient time on the Services to ensure that the Service Provider fully performs its obligations under this Agreement, in each case so long as such individuals are employed by Service Provider. Service Provider may, after obtaining Owner’s prior written consent (not to be unreasonably withheld), replace any Key Person with another employee of substantially equal experience and expertise as the Key Person being replaced, in which case the replacement employee shall become a Key Person. If any Key Person’s employment with Service Provider terminates for any reason or any Key Person is no longer providing the Services as required by this Section 2.6(b), Service Provider shall thereafter use commercially reasonable efforts, after obtaining Owner’s prior written consent (not to be unreasonably withheld), to promptly replace such Key Person with another employee of substantially equal experience and expertise as the Key Person being replaced, in which case the replacement employee shall become a Key Person.

(c)    Service Provider shall cause the Dedicated Employees to devote substantially all of their professional time and efforts to providing the Services so long as such individuals are employed by Service Provider. Service Provider may, after consultation with Owner, replace any Dedicated Employee with another employee of substantially equal experience and expertise as the Dedicated Employee being replaced or add Dedicated Employees as contemplated in Section 3.1(b), in which case the replacement employee or the added employee shall become a Dedicated Employee. Except as otherwise provided in Section 3.1(b), if any Dedicated Employee’s employment with Service Provider terminates for any reason or any Dedicated Employee is no longer providing the Services as required by this Section 2.6(c), Service Provider shall thereafter use commercially reasonable efforts, after consultation with Owner, to promptly replace such Dedicated Employee with another employee of substantially equal experience and expertise as the Dedicated Employee being replaced, in which case the replacement employee shall become a Dedicated Employee.

5

(d)    Service Provider shall cause the Shared Employees to devote at least one-third of their professional time and efforts to providing the Services so long as such individuals are employed by Service Provider. Service Provider may replace any Shared Employee with another employee of substantially equal experience and expertise as the Shared Employee being replaced, in which case the replacement employee shall become a Shared Employee. Except as otherwise provided in Section 3.1(b), if any Shared Employee’s employment with Service Provider terminates for any reason or any Shared Employee is no longer providing the Services as required by this Section 2.6(d), Service Provider shall thereafter use commercially reasonable efforts to promptly replace such individual with another employee of substantially equal experience and expertise as the Shared Employee being replaced, in which case the replacement employee shall become a Shared Employee.

2.7    Other Business Pursuits. The Owner Group acknowledges that Service Provider is not providing services exclusively to the Owner Group, and Service Provider may and will continue to from time to time provide services (including services substantially similar to the Services) to other persons (including Affiliates of Service Provider) as long as it may do so consistent with the dedication of Key Persons, Dedicated Employees and Shared Employees to the performance of the Services made under Section 2.6 and subject to any other written agreement between any member of the Owner Group and Service Provider or any of its Affiliates. After the Closing Date, prior to Service Provider or any of its Affiliates agreeing to provide any such services to any Third Party, Service Provider shall give the Owner Group written notice of the same.

2.8    Operatorship; Certain Conditions of Service.

(a)    Except as otherwise stated herein, Service Provider shall perform the Services as an “independent contractor” of the Owner Group and nothing in this Agreement is intended, and nothing shall be construed, to create an employer/employee, partnership, joint venture, association or other similar relationship between Service Provider and the Owner Group or any of their respective Affiliates or any of their employees.

(b)    All personnel involved in the Services shall be responsible to Service Provider. Subject to Section 2.6, the selection of such employees and contractors, and their hours of labor, shall be determined by Service Provider, and Service Provider shall have the right to hire or dismiss its full time or part time personnel for any reason or for no reason.

(c)    Subject to the terms of this Agreement, all matters pertaining to the employment, supervision, compensation, promotion and discharge of any personnel of Service Provider or its Affiliates are the responsibility of Service Provider and its Affiliates; provided, however, that Service Provider agrees that upon written notice from the Owner Group (stating adequate cause), Service Provider shall cause any Person identified by the Owner Group (including any employee of Service Provider or its Affiliates) to cease performing the Services on behalf of Service Provider. Subject to the terms of this Agreement, all such employment arrangements are solely Service Provider’s and its Affiliates’ obligations (including the payment of salaries and employee benefits with respect to such personnel).

2.9    Insurance. Service Provider shall maintain insurance of the type, in the amounts and with the limits, historically maintained by Service Provider in relation to the Assets. To the

6

extent that the cost of such insurance is within the scope of Section 3.3(b), the cost shall be an Owner Group Cost. To the extent that the cost of such insurance is not within the scope of Section 3.3(b), the cost shall be covered by the Services Fee. Service Provider shall require all contractors and subcontractors to carry insurance under terms usual and customary in the industry. Owner Group shall be named insured on Asset-level insurance (e.g., property and casualty insurance and liability insurance). If Owner Group desires to maintain any of such insurance itself, instead of having it provided by Service Provider, Owner Group may provide such insurance itself, and in such event the Services Fee will be reduced by the amount of any resulting savings of Service Provider in the insurance costs that are not Owner Group Costs. If Owner Group desires insurance coverage in excess of that maintained by Service Provider, it may acquire such additional coverage at its cost. Notwithstanding anything herein to the contrary, the Owner Group shall not be required to pay or reimburse Service Provider for any blanket or area-wide regulatory bonds maintained by Service Provider in performing the Services, and the Owner Group shall only be required to reimburse Service Provider for the Owner Group’s share (based on Owner’s ownership interest in the oil and gas interest underlying the Assets) of any regulatory bonds specific to any of the Assets.

2.10    Performance Standard. Service Provider shall perform the Services as a reasonable and prudent oil and gas operator, and in connection with matters not directly related to the operation of oil and gas assets in a reasonable manner in accordance with customary business practices, in a good and workmanlike manner, with due diligence and dispatch, in accordance with good oilfield practice, and in compliance with the terms of all applicable Leases, Applicable Contracts, Surface Contracts, and similar agreements affecting the Assets and/or this Agreement, and in compliance with all Laws. The standard of performance set forth in this Section 2.10 is referred to herein as acting as a “Reasonable and Prudent Service Provider”.

2.11    Meetings. Representatives of Owner Group shall have the right from time to time at the request of Owner to be present at and participate in internal Service Provider meetings in which the operation of the Assets and the performance of the Services are discussed by Service Provider personnel. In addition, representatives of Service Provider (which shall include Key Persons and other senior representatives of Service Provider requested by Owner and appropriate for the materiality and subject matter of the meeting) and the Owner Group shall meet telephonically, or otherwise at a mutually agreeable location, at least once per Calendar Month (or more frequently as requested by the Owner Group) on a mutually agreeable day and time to discuss the Services performed by Service Provider, the past, current or future operation and development of the Assets and/or any other matters with respect to the Assets or the business of the Owner Group reasonably requested by Owner or Service Provider.

2.12    Funds.

(a)    Funds belonging to the Owner Group shall be kept at all times on deposit in bank accounts of the Owner Group and Service Provider shall disburse such funds for the payment of costs and expenses incurred in connection with the Services that are Owner Group Costs, including all Asset Taxes and Burdens paid on Hydrocarbons, but excluding costs to be borne by Service Provider under the terms of this Agreement, and subject to the Development Plan and Budget and this Agreement.

(b)    At no time shall any of the Owner Group’s funds be commingled with funds belonging to Service Provider or its Affiliates or any of their respective representatives or with the funds of any Third Parties.

7

(c)    Service Provider shall direct all third parties making payments or otherwise transferring funds to the Owner Group to pay, transfer, and deposit such funds to the Owner Group directly into the bank accounts of the Owner Group.

(d)    If at any time Service Provider or any of its Affiliates comes into possession of any funds of the Owner Group, Service Provider shall hold such funds in trust for the benefit of the Owner Group and shall promptly cause such funds to be deposited into bank accounts of the Owner Group.

(e)    Service Provider shall not pay any monies from the accounts of the Owner Group to itself or any Affiliate of Service Provider without the prior written consent of Owner.

(f)    Third-party costs (and incremental internal costs of Service Provider incurred with the approval of Owner) of establishing, implementing, maintaining, and managing the accounts and systems required to accomplish the foregoing shall be Owner Group Costs. Service Provider shall use commercially reasonable efforts to cause the accounts and systems to be in place and operational on or prior to the Closing Date.

2.13    Master Service Agreements. The Parties acknowledge that Service Provider is not conveying any of its master services agreements to the Owner Group pursuant to the Transaction Agreements. After the Closing Date, subject to the terms of this Agreement, Service Provider shall be permitted to contract for Services with Third Party vendors through its master services agreements. Service Provider shall use commercially reasonable efforts, in the ordinary course of business, to enter into master services agreements with all vendors in the name of the Owner Group. Once any such master services agreement is in place, Service Provider shall thereafter contract for Services with the applicable Third Party vendor under the Owner Group’s master services agreement.

2.14    Seismic Licenses. Service Provider will not acquire or license any seismic data without the prior written consent of the Owner Group. In the event that Service Provider does acquire or license any such seismic data, the costs thereof will be Owner Group Costs and Service Provider will use commercially reasonable efforts to acquire or license such data in the name of the Owner Group with a right for the Service Provider to use such data as long as it is providing the Services hereunder. If Owner desires to co-license (or otherwise acquire the right to utilize) any seismic licenses currently utilized by Service Provider, the costs thereof will be Owner Group Costs.

2.15    Actions by Owner Group. Any action, consent or approval required to be taken hereunder by any member of the Owner Group shall be taken by Owner and any notices to be given to or by the Owner Group shall be given to Owner.

2.16    Owner’s Delegation of Authority. On an annual basis (and, as of the Closing Date, for the remainder of 2018), Owner shall execute and deliver to Service Provider a revocable written instrument substantially in the form attached hereto as Exhibit G designating and appointing Service Provider as its agent and attorney-in-fact with full power and authority to perform the Services (the “Annual Delegation”).

8

2.17    Certain Excluded Assets. The Parties have agreed that certain assets described in Exhibit E attached hereto that were utilized historically prior to the Closing Date in relation to the Assets but that were not acquired by the Owner Group on the Closing Date pursuant to the terms of the Transaction Agreements will be utilized by the Service Provider in connection with the performance of Services and that such assets will be assigned and transferred to the Owner Group at the time and in the manner set forth in Exhibit E. To the extent that any of the assets described on Exhibit E are held by Service Provider under a lease, license, or similar agreement, Service Provider shall use commercially reasonable efforts to maintain such leases, licenses, and other agreements in effect during the Term and the Transition Services Period and, if not previously assigned to Owner Group in accordance with Exhibit E, shall use reasonable efforts to assign such leases, license, and other agreements upon the termination of this Agreement. If Service Provider acquires any additional assets of the type described in Exhibit E that are used in relation to the Assets during the Term that were not paid for by the Owner Group as Owner Group Costs, if the Owner Group desires to have such assets transferred to it upon termination of this Agreement, Owner Group shall reimburse the Service Provider for the actual cost of such additional assets.

ARTICLE III.

PAYMENTS

3.1    Consideration.

(a)    Owner shall pay to Service Provider, (a) as the sole consideration for the Services provided by Service Provider, an amount equal to $23,563,531 per year during the Term and the Transition Services Period, prorated for any partial year in which the Services are provided (such amount, as modified from time to time pursuant to this Section 3.1, the “Services Fee”), plus (b) to the extent such costs and expenses have not been previously paid by Owner or out of Owner funds or otherwise reimbursed to Service Provider by Owner, reimbursement for all Owner Group Costs incurred by Service Provider in performing the Services, plus (c) any ▇▇▇▇▇ overhead fees related to the Assets operated by Owner Group that are received by Owner Group and any ▇▇▇▇▇ overhead fees payable directly by Owner Group under joint operating agreements applicable to the Assets operated by Owner Group (and for Assets operated by Owner Group not covered by a joint operating agreement, an amount equal to $8,500 per drilling well and $812 per producing well in the Austin Chalk producing area and $8,500 per drilling well and $844 per producing well in the Eagle Ford producing area, in both cases reduced to reflect Owner Group’s working interest, and as adjusted in accordance with ▇▇▇▇▇ MFI-47 (“Adjustment of Overhead Rates”)) (collectively, the “▇▇▇▇▇ Payment”). Owner shall pay to Service Provider with respect to each Calendar Month during the Term and the Transition Services Period an amount equal to one-twelfth of the excess of the Services Fee over the sum of any amount incurred directly by the Owner Group for Asset-level insurance in accordance with Section 2.9, and any amount Owner is entitled to deduct in accordance with Section 2.1(e), prorated for any partial Calendar Year in which the Services are provided (such amount, the “Monthly Services Fee”).

9

(b)    If after the Closing Date the Owner Group acquires, directly or indirectly, in a transaction that is not a Specified Acquisition, a material amount of additional assets with respect to which Owner desires to have the Services performed or additional assets within the Designated Area (in which case Service Provider shall perform the Services in respect of such assets), then such assets shall upon their acquisition become Assets hereunder, and the Services Fee shall be increased by the Service Provider’s reasonable, good-faith estimate of the amount of all incremental costs to be incurred by Service Provider that are not Owner Group Costs arising from any increase in the headcount of the Dedicated Employees and Shared Employees reasonably required in order for the Services to be performed with respect to such additional Assets and any other incremental costs (other than Owner Group Costs) that are reasonably required to be incurred by Service Provider to provide Services with respect to such Assets. If the Owner Group disposes of a material amount of Assets after the Closing Date, then the Services Fee shall be decreased by the Service Provider’s reasonable, good-faith estimate of the amount of savings in costs (other than Owner Group Costs) incurred by Service Provider arising from any decrease in the headcount of the Dedicated Employees and Shared Employees that reasonably may be made as a result of the disposition of such Assets and any other decrease in such costs that are reasonably required to be incurred by Service Provider to provide Services as a result of not having to provide Services with respect to the Assets disposed of. Any such decrease in headcount of Dedicated Employees and/or Shared Employees shall be subject to the approval of Owner. Service Provider will provide the Owner Group with reasonable documentation supporting any increase or decrease to the Services Fee pursuant to this Section 3.1(b) and an opportunity to review and audit such adjustments. If after the Closing Date the Owner Group consummates a Specified Acquisition, and the Owner desires to have the Services performed with respect to the assets that were acquired in such Specified Acquisition, the Service Provider will not be required to provide the Services with respect to such assets unless the Service Provider and the Owner mutually agree on an appropriate increase in the Services Fee to cover the Service Provider’s incremental costs that are not Owner Group Costs that Service Provider would incur in the performance of the Services with respect to such Assets. “Specified Acquisition” means the acquisition, directly or indirectly, of oil and gas properties and related assets if (a) the total value of the acquisition is greater than $1,000,000,000 or (b) the majority of the oil and gas properties acquired are outside of the Austin Chalk and Eagle Ford producing areas in South Texas.

(c)    If after the Closing Date the Owner Group increases the rig count attributable to the Assets above the levels specified in the initial Development Plan and Budget, the Services Fee shall be increased by the Service Provider’s reasonable, good-faith estimate of the amount of all incremental costs to be incurred by Service Provider that are not Owner Group Costs arising from any increase in the headcount of the Dedicated Employees and Shared Employees reasonably required as a result of such increase, taking into account the additional ▇▇▇▇▇ Payments that will be received by Service Provider as a result of the increase and which might result in double-recovery of costs by Service Provider. If, after an increase of the Services Fee pursuant to the foregoing, there is a decrease in the rig count attributable to the Assets, the Services Fee shall be reduced by the Service Provider’s reasonable, good faith estimate of the reduction in costs to be realized by Service Provider that are not Owner Group Costs arising from any decrease in the headcount of the Dedicated Employees and Shared Employees reasonably resulting from such decrease; provided, however, that such decrease shall not cause the Services Fee to drop below the amount of the Services Fee as of the Closing Date.

10

(d)    Service Provider will be entitled to keep, receive and retain all ▇▇▇▇▇ overhead fees received by Service Provider in relation to the Assets operated by Owner Group.

3.2    Payment Terms.

(a)    No later than the thirtieth (30^th) day of each Calendar Month, Service Provider shall deliver to Owner a monthly statement (each, a “Monthly Statement”) setting forth (i) the Monthly Services Fee for the preceding Calendar Month, (ii) an itemized list of Owner Group Costs not paid directly from Owner Group funds that were incurred by Service Provider during the applicable Accounting Month, and (iii) the ▇▇▇▇▇ Payment for the applicable Accounting Month. Service Provider shall provide to Owner such documentation as Owner may reasonably request to support each such Monthly Statement. Subject to Section 3.2(b), Owner shall pay to Service Provider the amount reflected in such Monthly Statement not later than the 30^th day after the receipt of such Monthly Statement.

(b)    If Owner disputes in good faith all or any portion of any Monthly Statement delivered by Service Provider pursuant to this Agreement, Owner may deliver written notice of such dispute to Service Provider, setting forth in reasonable detail the reasons for such dispute. Notwithstanding the delivery of any such written notice of dispute, Owner shall pay, if applicable, to Service Provider the undisputed portions of such Monthly Statement in accordance with the terms of this Agreement. If it is determined by the Parties or otherwise that any amount is owed by either Party to the other Party hereunder, then the owing Party shall promptly (but in any event within five (5) Business Days after such determination) reimburse the other Party such amount.

(c)    All payments shall be made by wire transfer of immediately available funds, to the account (or accounts) designated by the Person entitled to receipt of such payment.

3.3    Owner Group Financial Responsibility. The Owner Group shall be ultimately responsible for the payment (either directly or via reimbursement of the Service Provider) for the following costs (“Owner Group Costs”):

11

3.4    Maintenance of Accounts and Records.

(a)    Service Provider shall maintain on behalf of the Owner Group all Records and other records, books, accounts, files, data, and other information that are required hereunder to be maintained by the Service Provider (other than the books and records of Service Provider referred to in Section 3.5) (such records, books, accounts, files, data, and other information, the “Owner Records and Data”). All Owner Records and Data maintained in electronic form shall be logically separate from all electronic records and data of Service Provider and its Affiliates. Service Provider shall ensure that no Persons other than authorized Persons will be able to access such Owner Records and Data, with the Persons so authorized being only those Persons for which access is reasonably necessary for the performance of the Services. Service Provider shall ensure that Owner Group and its representatives have reasonable access to all Owner Records and Data (including all Owner Records and Data maintained in electronic form), in the case of physical records during reasonable business hours physically at the location at which such books and records are maintained, in each case to the greatest extent practicable as if such Owner Records and Data were maintained by Owner on its own behalf. All such Owner Records and Data shall be the property of the Owner Group and shall be delivered to Owner at Service Provider’s cost at the end of the Term and any Transition Services Period, together with the information systems on which electronic Owner Records and Data are maintained, including copies of all databases and other system applications in which such Owner Records and Data are maintained.

(b)    Service Provider shall maintain, separately and in accordance with GAAP, on behalf of the Owner Group, as Owner Records and Data, complete and accurate books of account and financial records reflecting the results of operations of the Owner Group relating to the Assets, including (a) complete and accurate accounts and records of all Owner Group Costs and all other expenses, costs, and liabilities accrued or incurred by or on behalf of the Owner, including all Asset Taxes and Burdens paid on Hydrocarbons in connection with the Assets, and (b) complete and accurate accounts and records of all revenues accrued, invoiced, and/or received by Owner in connection with the Assets. Service Provider shall, at the request of the Owner Group, carry out or cause to be carried out an annual Asset-level audit of such books and records and shall assist Owner and its representatives in connection with the preparation by Owner of the Owner Group audited financial statements. Service Provider shall provide to Owner Group an annual service organization control report (“Annual SOC Report”) for the benefit of Owner Group. Owner Group shall pay all fees and other amounts payable to the SOC Service Provider and shall pay Service Provider for the personnel costs actually incurred by Service Provider for one Service Provider employee (not already a Dedicated Employee or Shared Employee) while such employee is dedicated to overseeing the Annual SOC Report and interfacing with the SOC Service Provider.

12

Owner in its reasonable discretion shall specify the scope and content of each Annual SOC Report, to be provided to its financial statement auditors, and the service provider (the “SOC Service Provider”) that will be retained to prepare each Annual SOC Report, and Service Provider will retain the SOC Service Provider. Service Provider shall maintain any operations-related information that normally would be included as part of such accounting documentation, including invoices, operating and maintenance records, volumes of production, price received for hydrocarbon sales, lease operating expenses, processing charges, gathering and transportation expenses, cash collections, cash payments and property tax allocations.

3.5    Taxes. Service Provider shall be responsible for all (i) income taxes resulting from amounts paid or payable to it under this Agreement, (ii) employment taxes and social security payments relating to its own employees, and (iii) all other taxes incurred by Service Provider that do not constitute Owner Group Costs. For the avoidance of doubt, Service Provider, and not Owner, shall treat the providers of services under this Agreement as employees for tax purposes.

3.6    Service Provider Records; Audit.

(a)    Service Provider shall maintain complete and accurate books and records of its activities in connection with the performance of the Services, including any Owner Group Costs actually paid by Service Provider from its own funds.

(b)     Upon not less than ten (10) Business Days’ prior written notice to Service Provider during the Audit Period for any particular Calendar Year, Owner shall have the right to audit Service Provider’s books and records for the Calendar Year to which the Audit Period applies, and the costs charged to Owner in that Calendar Year. The cost of each such audit shall be borne by Owner; provided, that, if any material amounts are determined to be owed by Service Provider to Owner as a result of such audit, then Service Provider shall reimburse Owner for such cost of audit. Unless otherwise mutually agreed, any audit shall be conducted at the principal office of Service Provider.

(c)    Owner may request information prior to the commencement of the audit, and Service Provider shall, to the extent available, provide the information requested as soon as practical in order to facilitate the forthcoming audit.

3.7    Disputed Charges. Owner may, during the Audit Period for any particular Calendar Year, take written exception to any invoice rendered by Service Provider for any expenditure or any part thereof charged to Owner in that Calendar Year, on the ground that the same was not a cost incurred by Service Provider for which Service Provider is entitled to reimbursement pursuant to this Agreement. If the amount as to which such written exception is taken or any part thereof is ultimately determined to be a cost for which Service Provider is not entitled to reimbursement pursuant to this Agreement, such amount or portion thereof (as the case may be) shall be paid by Service Provider to Owner together with interest at the Agreed Rate.
