“Services”).

Agreement, Noble shall pay all expenses incurred by it in connection with the retention of the Seconded 

  
 3 








 
Persons, including, but not limited to, Seconded Employee compensation, salaries, wages and overhead and administrative expenses, charged to or incurred by Noble, and, if applicable, social
security taxes, workers compensation insurance, retirement and insurance benefits and other such expenses. Any Seconded Employees retained by Noble may be union or non-union employees, and Noble 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 Noble shall provide, or cause to
be provided, such suitably qualified and experienced Seconded Persons as Noble is able to make available to the Partnership Parties, and the Partnership Parties shall have the right to approve such Seconded Persons. 

2.4 During the term of this Agreement, Noble shall second employees of the Noble Entities that provide the Services to the Partnership
Parties. Each employee who Noble 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, Noble shall second contractors of the Noble Entities that provide the Services to the Partnership Parties. Each such contractor who Noble seconds to the Partnership Parties 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 Noble Entities, but, in addition, during the Period of Secondment,
they will also be joint employees of the Partnership Parties. 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
Noble. Noble retains 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 Noble. The Partnership Parties will have the right to
terminate the Secondment to it of any Seconded Persons for any reason at any time, upon prior written notice to Noble, but at no time will the Partnership Parties have the right to terminate any Seconded Employee’s employment by a Noble Entity
or a Seconded Contractor’s independent contractor relationship with a Noble Entity. Upon the termination of the Secondment of any Seconded Persons, such Seconded Persons will cease performing Services for the Partnership Parties. 

2.7 In the course and scope of performing any job functions for the Partnership Parties, each Seconded Employee will report into the
Partnership Parties’ management structure, and will be under the direct management, supervision and control of the Partnership Parties with respect to such Seconded Employee’s performance of the Services, with Seconded Contractors
remaining at the direction of the respective contractor. No Seconded Persons shall have the authority or apparent authority to act on behalf of Noble 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 Partnership Parties as supervisors to act on the behalf of the Partnership Parties in supervising the Seconded Employees pursuant to
Section 2.7 above. Any such Seconded Employee will be acting on the behalf of the Partnership Parties when supervising the work of the Seconded Employees or when they are otherwise providing management or executive support on behalf of the
Partnership Parties. 

  
 4 








 2.9 Noble shall obtain workers’ compensation coverage as defined and required by law
on behalf of both Noble 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 Noble. In the event the Partnership Parties, or any of them, terminates such Services, the Partnership Parties shall pay Noble 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 Noble pursuant to this Agreement with respect to such terminated
Services. 
 2.11 No member of the Partnership Parties 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, Noble 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. Noble 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 Noble for all reimbursable expenses under Section 3.2 incurred
by Noble with respect to Seconded Persons (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 costs) incurred for such period by Noble for the Seconded Employees
(including, where applicable, former Seconded Employees), including but not limited to the following costs and expenses set forth below: 
  

	 	(i)	salary, wages and cash bonuses (including payroll and withholding taxes associated therewith); 

  

	 	(ii)	amounts paid with respect any Seconded Employee’s paid leave of absence; 

  

	 	(iii)	contributions made by Noble towards any Benefit Plans; 

  

	 	(iv)	the value of equity-related compensation granted to Seconded Employees during the Period of Secondment; 

  

	 	(v)	any other employee benefit or compensation arrangement customarily provided to all employees by Noble for which Noble incurs costs with respect to Seconded Employees; and 


  
 5 









	 	(vi)	business travel expenses and other business expenses reimbursed in the normal course by Noble, such as subscriptions to business-related periodicals and dues to professional business organizations. 


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 Noble shall mutually agree on the method of 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 Noble, or in such manner as may be otherwise agreed between
Noble and the GP. 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 Noble employees. 
 (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 Noble 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 Noble 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 Noble (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 Noble acknowledge and agree that Noble 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 Noble may be responsible for paying the Seconded Contractor Expenses to the respective
contractor, but that the Partnership Parties shall be responsible for reimbursing Noble 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 Noble or any Affiliate of Noble incurs any out-of-pocket expenses (other than the Services Reimbursement) in connection with the provision of Services, Noble or such Affiliate may be entitled to reimbursement
therefor under the terms of the Partnership Agreement or the Omnibus Agreement.

 ARTICLE 4 

ALLOCATION; RECORDS 
 Noble
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
thirty (30) days prior written notice to Noble and only those provisions that, by their terms, expressly survive this Agreement shall so survive. 

ARTICLE 6

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. 

  
 7 








 6.5 Partial Invalidity. Wherever possible, each provision hereof shall be
interpreted in such a manner as to be effective and valid under applicable law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision or
provisions shall be ineffective to the extent, but only to the extent, of such invalidity, illegality or unenforceability without invalidating the remainder of such provision or provisions or any other provisions hereof, unless such a construction
would be unreasonable.

their successors and permitted assigns. The successors and permitted assigns hereunder shall include any permitted assignee under Section 6.10 as well as the successors in interest to such permitted assignee (whether by merger,
