ARTICLE 2

SECONDMENT

2.1    Diamondback shall provide, or cause to be provided, to the Partnership Parties the Seconded Persons to (a) perform the activities related to the Partnership Parties’ respective obligations under each of the agreements listed in Exhibit A, (b) otherwise perform the day-to-day management of the assets of the Midstream Group and the business conducted, or to be conducted, by the Partnership Parties described in Exhibit A, (c) to design, build, construct and otherwise install the infrastructure required by (or necessary or convenient to provide the services required under) the agreements listed in Exhibit A and (d) perform the management, general and administrative services described in Exhibit A, to be received by the General Partner, for the benefit of the Partnership Parties, at the places of business of the General Partner ((a) through (d) collectively referred to herein as the “Services”).

2.2    Subject to Diamondback’s right to be reimbursed for such expenses in accordance with this Agreement, Diamondback shall pay (or shall cause E&P to pay) all expenses incurred by it in connection with the retention of the Seconded Persons, including, but not limited to, Seconded Employee compensation, salaries, wages, benefit costs, overhead and administrative expenses, charged to or incurred by Diamondback or E&P, and, if applicable, social security taxes, workers compensation insurance, retirement and insurance benefits and other such expenses. Any Seconded Employees retained by the Diamondback Entities may be union or non-union employees, and the Diamondback Entities shall have the sole right to negotiate the terms and provisions of any labor or other agreements with the unions to which such employees belong.

2.3    Diamondback shall provide, or cause to be provided, such suitably qualified and experienced Seconded Persons as Diamondback is able to make available to the Partnership Parties, and the Partnership Parties shall have the right to approve such Seconded Persons.

4

2.4    During the term of this Agreement, Diamondback or E&P shall second employees of the Diamondback Entities that provide the Services to the Partnership Parties. Each employee who Diamondback or E&P seconds to the Partnership Parties shall, during the time that such employee is seconded to the Partnership Parties under this Agreement (the “Period of Secondment”), be referred to individually herein as a “Seconded Employee” and, collectively, as the “Seconded Employees.”

2.5    During the term of this Agreement, Diamondback shall second, or cause to be seconded, contractors of the Diamondback Entities that provide the Services to the Partnership Parties. Each such contractor shall, during the Period of Secondment, be referred to individually herein as a “Seconded Contractor” and, collectively, as the “Seconded Contractors,” and together with the Seconded Employees, the “Seconded Persons.”

2.6    The Seconded Employees will remain at all times employees of the applicable Diamondback Entities. For the avoidance of doubt, the Parties acknowledge that Seconded Persons may, during the Period of Secondment, be called upon to perform services for both the Partnership Parties and the Diamondback Entities. The Diamondback Entities retain the right to terminate the Secondment of any Seconded Persons for any reason at any time or to discharge the Seconded Employees with respect to their employment with the Diamondback Entities. During the Term, the Partnership Parties shall have the right to request that Diamondback remove any individual from the roster of Seconded Employees providing Services to the Partnership Entities. Diamondback agrees that it will remove any such individual from the status of a Seconded Employee upon written request by any Partnership Party. Diamondback shall have the sole right, with or without the consent of the Partnership Parties, to terminate the employment of any Seconded Employee. However, the parties agree that the Partnership Parties shall have the sole right to determine the level of Services required from the Seconded Persons and its satisfaction with the performance of such Services by the Seconded Employees in connection with the Services and that Diamondback will use commercially reasonable efforts to provide Seconded Employees in a manner consistent with the needs expressed by any Partnership Party, but at no time will any Partnership Party have the right to terminate any Seconded Person, including any Seconded Employee’s employment by a Diamondback Entity or a Seconded Contractor’s independent contractor relationship with a Diamondback Entity. Upon the termination of the Secondment of any Seconded Persons, such Seconded Persons will cease performing Services for the Partnership Parties.

(a)    The Parties agree that Diamondback and each of its Affiliates and agents shall perform the Services hereunder in the capacity of an independent contractor. The Seconded Employees shall continue to be the common law employees of the Diamondback Entities and shall have no employment or contractual relationship with the Partnership Parties during the Term. The Partnership Parties shall not hold out the Seconded Employees as agents of Diamondback in the course of the performance by the Seconded Employees of their duties in respect of the Services.

(b)    The Partnership Parties shall be responsible for specifying to Diamondback the day-to-day manner of operations and assignments for Seconded Employees and reviewing the work performed by the Seconded Employees to determine whether the Services rendered in connection with the Agreement are consistent with the results to be achieved, as specified by the Partnership Parties. Nothing in this Agreement shall preclude the Partnership Parties from hiring

5

or employing any employees during the Term of this Agreement; provided, however, that the Diamondback Entities shall have no obligation to provide and shall not provide any employee benefits, payroll or HR Services to or with respect to any employees of the Partnership Parties.

2.7    Each Party shall nominate a representative to act as its primary contact with respect to the provision of the Services contemplated by this Agreement (each, a “Service Coordinator”). The initial Service Coordinators shall be designated by the respective parties following the Effective Date. Unless otherwise agreed, all notices and communications relating to this Agreement, other than those day-to-day communications and billings relating to the actual provision of the Services, shall be directed to the Service Coordinators. In the course and scope of performing any job functions for the Partnership Parties, each Seconded Employee will report to the Diamondback management structure and the Diamondback management structure, through the Diamondback Service Coordinator will report into the Partnership Parties’ management structure through the Partnership Parties Service Coordinator. However, Seconded Employees will be under the direct management, supervision and control of the Diamondback Entities with respect to such Seconded Employee’s performance of the Services, with Seconded Contractors remaining at the direction of the respective contractor. No Seconded Contractors shall have the authority or apparent authority to act on behalf of any Diamondback Entity in connection with the performance of the Services during any Period of Secondment.

2.8    Those Seconded Employees who serve as supervisors or managers and who are called upon to oversee the work of other Seconded Employees providing or to otherwise provide management support on behalf of the Parties are designated by the Diamondback Entities as supervisors to act on the behalf of the Diamondback Entities in supervising the Seconded Employees pursuant to Section 2.7 above. Any such Seconded Employee will be acting on the behalf of the Diamondback Entities when supervising the work of the Seconded Employees or when they are otherwise providing management or executive support in connection with the Services performed on behalf of the Partnership Parties.

2.9    Diamondback shall, or shall cause a Diamondback Entity to, obtain workers’ compensation coverage as defined and required by law on behalf of both the Diamondback Entities and the Partnership Parties.

2.10    The Partnership Parties may terminate any of the Services performed by Seconded Persons on thirty (30) days’ prior written notice to Diamondback. In the event the Partnership Parties, or any of them, terminates such Services, the Partnership Parties shall pay Diamondback the Services Reimbursement (as defined below) for the last month (or portion thereof) in which it received such terminated Services. Upon payment thereof, the Partnership Parties shall have no further Services payment obligations to Diamondback pursuant to this Agreement with respect to such terminated Services.

2.11    No Partnership Party shall be deemed to be a participating employer in any Benefit Plans during the Period of Secondment. Subject to the Partnership Parties’ reimbursement obligations hereunder, Diamondback (or another Diamondback Entity) shall remain solely responsible for all obligations and liabilities arising under the express terms of the Benefit Plans, and the Seconded Employees will be covered under the Benefit Plans subject to and in accordance with their respective terms and conditions, as they may be amended from time to time.

6

Diamondback and its ERISA Affiliates may amend or terminate any Benefit Plans in whole or in part at any time (subject to the applicable provisions of any collective bargaining agreement covering Seconded Employees, if any). During the Period of Secondment, no member of the Partnership Parties shall assume any Benefit Plans or have any obligations, liabilities or rights arising under the express terms of the Benefit Plans, in each case except for cost reimbursement pursuant to this Agreement.

ARTICLE 3

EXPENSE REIMBURSEMENT

3.1    The Partnership Parties shall reimburse Diamondback or E&P, as applicable, for all reimbursable expenses under Section 3.2 incurred by the Diamondback Entities with respect to Seconded Persons, as applicable (including, where applicable, former Seconded Employees), in connection with the performance of the Services during the preceding period (the “Services Reimbursement”). The Services Reimbursement shall be made on a monthly basis or at such other intervals as the Parties may agree from time to time.

3.2    (a) The Services Reimbursement with respect to Seconded Employees for each period during the Period of Secondment shall include all reasonable costs and expenses (including administrative and benefits costs) incurred for such period by Diamondback Entities for the Seconded Employees (including, where applicable, former Seconded Employees), including but not limited to the following costs and expenses set forth below:

The costs and expenses described in this Section 3.2(a) are referred to as “Seconded Employee Expenses.” Where it is not reasonably practicable to determine the amount of such a cost or expense, the Partnership Parties and Diamondback shall mutually agree on the method of

7

determining or estimating such cost or expense. If the actual amount of any cost or expense, once known, varies from the estimate used for billing purposes hereunder, the difference, once determined, shall be reflected as either a credit or additional charge in the next monthly invoice issued by a Diamondback Entity, or in such manner as may be otherwise agreed between Diamondback and the General Partner. Notwithstanding the foregoing, the Parties agree that to determine the value of a Second Employee’s non-wage benefits described in subsections (iii) and (v) of this Section 3.2(a), they will apply an agreed percentage benefit load, based on the value of employee benefits provided to all employees of the Diamondback Entities.

(b)    The Services Reimbursement with respect to Seconded Contractors for each period during the Period of Secondment shall include, on a pass-through basis, all costs and expenses attributable to the performance of the Services incurred for such period by Diamondback Entities with respect to the Seconded Contractors. The costs and expenses described in this Section 3.2(b) are referred to as “Seconded Contractor Expenses,” and together with the Seconded Employee Expenses, the “Seconded Person Expenses.”

3.3    With respect to those Seconded Persons who perform services for both the Diamondback Entities and the Partnership Parties, the Parties will determine in good faith the percentage of such Seconded Person’s time spent providing services to the Partnership Parties (the “Allocation Percentage”). For each month, or other time interval agreed to by the Parties, during the Period of Secondment, the amount of the Services Reimbursement payable by the Partnership Parties with respect to each Seconded Person shall be calculated by multiplying the Seconded Person Expenses for such Seconded Person times the Allocation Percentage for such Seconded Person; provided, however, that travel expenses and other expenses incurred with respect to and/or reimbursable to a Seconded Person shall be paid by the Party for whom the Seconded Person was working at the time they were incurred, except that expenses related to activities that benefit both the Partnership Parties and Diamondback Entities (e.g. some types of training) shall be shared by the affected Parties in accordance with the Allocation Percentage (or such other allocation as may be agreed between the affected Parties).

3.4    The Partnership Parties and Diamondback acknowledge and agree that Diamondback shall be responsible for paying the Seconded Employee Expenses (or providing the employee benefits with respect thereto, as applicable) to the Seconded Employees and that the Diamondback Entities may be responsible for paying the Seconded Contractor Expenses to the respective contractor, but that the Partnership Parties shall be responsible for reimbursing the Diamondback Entities for the Seconded Person Expenses (as part of the Services Reimbursement) to the extent provided under Section 3.2 of this Agreement.

3.5    This Agreement does not address the reimbursement of any costs or expenses associated with Services other than the Services Reimbursement. To the extent that a Diamondback Entity incurs any out-of-pocket expenses (other than the Services Reimbursement) in connection with the provision of Services, such Diamondback Entity may be entitled to reimbursement therefor under the terms of the Partnership Agreement or other documentation.

8

ARTICLE 4

ALLOCATION; RECORDS

Diamondback will use commercially reasonable efforts to (i) establish the Allocation Percentage and to the document the basis for such allocation and (ii) maintain a schedule reflecting the direct and indirect costs of the Seconded Person Expenses based on the Services that the Seconded Persons have provided to the Partnership Parties. The Partnership Parties will use commercially reasonable efforts to keep and maintain books/records reflecting the hours worked in connection with each of the Seconded Persons. Each Party will have the right to audit such records maintained by the other during regular business hours and on reasonable prior notice.

ARTICLE 5

TERM

The term of this Agreement will commence on the Effective Date and will continue for an initial period of fifteen (15) years (the “Initial Term”). Upon the expiration of the Initial Term, the term of this Agreement shall automatically extend for successive one year extension terms, unless either Party provides at least thirty (30) days’ prior written notice to the other Party prior to the expiration of the Initial Term or any extension term that the Party wishes for this Agreement to expire at the end of the Initial Term or the then-current extension term, as applicable. Upon proper notice by a Party to the other Party, in accordance with this Article 5, that the Party wishes for this Agreement to expire on the expiration of the applicable period, this Agreement shall not automatically extend, but shall instead expire upon the expiration of the applicable period and only those provisions that, by their terms, expressly survive this Agreement shall so survive. Notwithstanding the foregoing, the Partnership Parties may terminate this Agreement at any time upon written notice to Diamondback stating the date of termination and only those provisions that, by their terms, expressly survive this Agreement shall so survive.

ARTICLE 6

Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any Party, it is in writing signed by an authorized representative of such Party. The failure of any Party to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, or in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

9

6.5    Severability. Whenever possible each provision and term of this Agreement will be interpreted in a manner to be effective and valid. If any term or provision of this Agreement or the application of any such term or provision to any Person or circumstance shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, the remaining provisions hereof, or the application of such term or provision to Persons or circumstances other than those as to which it has been held invalid, illegal or unenforceable, will remain in full force and effect and will in no way be affected, impaired or invalidated thereby.
