SECONDMENT

2.1 Seconded Employees. Subject to the terms of this Agreement, Hess agrees to second the Seconded Employees to the General Partner, and the General Partner agrees to accept the Secondment of the Seconded Employees for the purpose of performing job functions related to the Assets, including those job functions set forth on Exhibit B (the “Employee Functions”). The Seconded Employees will remain at all times the employees of Hess, and will also be co-employees of the General Partner during the Period of Secondment. The Seconded Employees shall, at all times during the Period of Secondment, work under the direction, supervision and control of the General Partner. Seconded Employees shall have no authority or apparent authority to act on behalf of Hess during the Period of Secondment. Those rights and obligations of the Parties under this Agreement that relate to individuals that were Seconded Employees but then later ceased to be Seconded Employees, which rights and obligations accrued during the Period of Secondment, will survive the removal of such individual from the group of Seconded Employees to the extent necessary to enforce such rights and obligations.

2.2 Period of Secondment. Hess will second the Seconded Employees to the General Partner starting on the Effective Date and continuing, during the period (and only during the period) that the Seconded Employees are performing functions for the General Partner, until the earliest of:

2

The period of time that any Seconded Employee is provided by Hess to the General Partner is referred to in this Agreement as the “Period of Secondment.” At the end of the Period of Secondment for any Seconded Employee, such Seconded Employee will no longer be subject to the direction by the General Partner of the Seconded Employee’s day-to-day activities. The Parties acknowledge that the Seconded Employees may also perform functions for Hess in connection with its operations and the Parties intend that the Seconded Employees shall be seconded to the General Partner only during those times that the Seconded Employees are performing functions for the General Partner hereunder.

2.3 Withdrawal, Departure or Resignation. Hess will use reasonable efforts to prevent any early withdrawal, departure or resignation of any Seconded Employee prior to the End Date for such Seconded Employee’s Period of Secondment. If any Seconded Employee tenders his or her resignation to Hess as an employee of Hess, Hess will promptly notify the General Partner. During the Period of Secondment of any Seconded Employee, Hess will not voluntarily withdraw or terminate any Seconded Employee except with the written consent of the General Partner, such consent not to be unreasonably withheld. Hess will indemnify, defend and hold harmless the General Partner, its directors, officers and employees against all Losses arising out of or in any way connected with or related to the termination of employment of the Seconded Employee by Hess EVEN THOUGH SUCH LOSS MAY BE CAUSED BY THE NEGLIGENCE OF ONE OR MORE OF THE PARTNERSHIP ENTITIES, except to the extent that such Losses arise out of or result from the sole negligence, gross negligence or willful misconduct of any of the Partnership Entities. Upon the termination of employment, the Seconded Employee will cease performing services for the General Partner.

2.4 Termination of Secondment. The General Partner will have the right to terminate the Secondment of any Seconded Employee for any reason at any time. Upon the termination of any Seconded Employee’s Period of Secondment, Hess will be solely liable for any costs or expenses associated with the termination of the Secondment, except as otherwise specifically set forth in this Agreement. Hess will indemnify, defend and hold harmless the General Partner, its directors, officers and employees against all Losses arising out of or in any way connected with the termination of Secondment of the Seconded Employee by Hess EVEN THOUGH SUCH LOSS MAY BE CAUSED BY THE NEGLIGENCE OF ONE OR MORE OF THE PARTNERSHIP ENTITIES, except to the extent that such Losses arise out of or result from the sole negligence, gross negligence or willful misconduct of any of the Partnership Entities. Upon the termination of a Secondment, the Seconded Employee will cease performing functions for the General Partner.

2.5 Supervision.

(a) During the Period of Secondment, the General Partner will serve as the employer directly controlling the personnel providing Employee Functions and will retain the exclusive right, solely to the extent it relates to the Period of Secondment, to:

(i) be ultimately and fully responsible for the daily work assignments of the Seconded Employees during those times that the Seconded Employees are performing functions for the General Partner hereunder, including supervision of their the day-to-day work activities and ensuring that such Seconded Employee’s performance is consistent with the purposes stated in Section 2.1 and the job functions associated with the Employee Functions;

3

(ii) to handle any performance issues of Seconded Employees;

(iii) set the hours of work and the holidays and vacation schedules for Seconded Employees; and

(iv) have the right to determine training that will be received by the Seconded Employees.

(b) Notwithstanding the foregoing, Hess shall be responsible for administering the payment of each Seconded Employee’s wages and benefits, all withholding obligations to federal, state and local tax and insurance authorities, and all other costs and expenses associated with Seconded Employees, including workers’ compensation expense.

(c) In the course and scope of performing any Seconded Employee job functions, the Seconded Employees will be integrated into the organization of the General Partner, will report into the General Partner’s management structure, and will be under the direct management and supervision of the General Partner, in its capacity as the general partner of the Partnership.

2.6 Seconded Employee Qualifications; Approval. Hess will provide such suitably qualified and experienced Seconded Employees as Hess is able to make available to the General Partner, and the General Partner will have the right to approve such Seconded Employees. All Seconded Employees identified as of the Effective Date have been approved and accepted by the General Partner as suitable for performing job functions related to the Employee Functions.

2.7 Workers’ Compensation Insurance. At all times, Hess will maintain workers’ compensation or similar insurance (either through an insurance company or self-insured arrangement) applicable to the Seconded Employees, as required by applicable state and federal workers’ compensation and similar laws.

2.8 Benefit Plans. Neither the General Partner nor any of the Partnership Entities shall be deemed to be a participating employer in any Benefit Plan during the Period of Secondment. Subject to the General Partner’s reimbursement obligations hereunder, Hess 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 may be amended from time to time. Hess and its ERISA Affiliates may amend or terminate any Benefit Plan in whole or in part at any time. During the Period of Secondment, neither the General Partner nor any of the Partnership Entities shall assume any Benefit Plan 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

SECONDMENT FEE

3.1 Secondment Fee.

(a) The General Partner shall pay to Hess an annual fee, payable in equal monthly installments, that will reflect the costs incurred by Hess with respect to its employment of the Seconded Employees (the “Secondment Fee”). The Parties acknowledge and agree that the Secondment Fee is intended to cover the total cost of employing the Seconded Employees during the Period of Secondment (the “Total Services Costs”) to the extent such Total Services Costs are attributable to the provision of the Employee Functions. Hess shall determine in good faith the percentage of the Total Services Costs that are attributable to the provision of the Employee Functions by the Seconded Employees to the General Partner based on Hess’s then-current corporate transfer pricing policies, as generally applied in a non-discriminatory manner. To the extent that the amount of any cost or expense, once known, varies from the estimate used for determining the Secondment Fee hereunder, the difference, once determined, shall be added to or subtracted from the Secondment Fee for the following year.

(b) For the avoidance of doubt, the Secondment Fee shall not include any costs associated with equity-based compensation granted by Hess or the General Partner to the Seconded Employees; provided, however, that to the extent the General Partner grants any awards under any incentive compensation plan of the Partnership or the General Partner in effect from time to time, such awards shall be at the General Partner’s sole expense and the General Partner shall reimburse Hess for any expenses Hess may incur with respect to such awards.

(c) The Parties acknowledge and agree that the Secondment Fee may change from time to time, as determined by Hess in good faith, to accurately reflect the degree and extent of the Employee Functions provided to the General Partner by the Seconded Employees or to reflect any change in the cost of employing the Seconded Employees. On or prior to January 1 of each calendar year during the term of this Agreement, Hess will provide the General Partner with an estimate of the Secondment Fee for the succeeding calendar year, and such Secondment Fee will be invoiced to the General Partner in accordance with this Section 3.1(c).

(d) Within 20 days following the end of each month during the Period of Secondment, Hess shall send to the General Partner an invoice (in a form mutually agreed by the Parties) of the amounts due for such month setting forth the applicable portion of the Secondment Fee payable for such month and any amounts reimbursable under this Agreement. The General Partner shall, or shall cause the Partnership Entities to, pay such invoice by the later of (i) thirty days of receipt and (ii) the last Business Day of the month in which the General Partner received such invoice, except for any amounts that are being disputed in good faith by the General Partner. If Hess determines that the amount reflected on any invoice previously sent to, and paid by, the General Partner did not accurately state the amounts owed by the General Partner under this Section 3.1, Hess shall include appropriate adjustments on the next invoice; provided, however, that such adjustments shall be included only to the extent that they relate to a month in the same calendar quarter as such invoice relates; provided further that Hess and the General Partner shall negotiate, in good faith, the timing of payment of any such adjustments. Any such adjustments shall be separately stated and computed in such detail as is mutually agreed by Hess

5

and the General Partner. For the avoidance of doubt, any adjustments that do not relate to a month in the same calendar quarter as such invoice relates shall not be due and payable by the General Partner. Any amounts that the General Partner has disputed in good faith and that are later determined by any court or other competent authority having jurisdiction, or by agreement of the Parties, to be owing from the General Partner to Hess shall be paid in full within ten days of such determination, together with interest thereon at the Interest Rate from the date due under the original invoice until the date of payment. For long as the General Partner is an Affiliate of Hess, the General Partner and Hess may settle the General Partner’s financial obligations to Hess through Hess’s normal interaffiliate settlement processes.

3.2 Cancellation or Reduction of Services. The General Partner may terminate or reduce the level of any of the Employee Functions on 30 days’ prior written notice to Hess. In the event the General Partner terminates the Employee Functions, the General Partner shall pay Hess the applicable monthly portion of the Secondment Fee for the last month (or portion thereof) in which it received Employee Functions. Upon payment thereof, the General Partner shall have no further payment obligation to Hess under this Agreement.

3.3 Reimbursements for Other Costs and Expenses. This Agreement does not address the reimbursement of any costs or expenses associated with any services provided by Hess and its Affiliates other than the Employee Functions. For the avoidance of doubt, any amounts payable by the General Partner under this Agreement shall be in addition to, and not in duplication of, any amounts payable by the General Partner or any Partnership Entity under the Omnibus Agreement or the Operational Services Agreement.

ARTICLE 4

ALLOCATION; RECORDS

4.1 Allocation; Records. Hess will use commercially reasonable efforts to maintain an allocation schedule reflecting the direct and indirect costs that are included in the calculation of the Secondment Fee. The General Partner and its representatives will have the right to audit such records and such other records as the General Partner may reasonably require in connection with its verification of the Secondment Fee during regular business hours and on reasonable prior notice.

4.2 Agent. The costs and expenses included in the Secondment Fee remain the primary legal responsibility of the General Partner as the co-employer of the Seconded Employees during the Secondment Period. Hess agrees to act as agent for the General Partner in paying such amounts to the employees temporarily assigned under this Secondment Agreement. Hess agrees to indemnify and hold the General Partner harmless from any and all Losses incurred by the General Partner or any of the other Partnership Entities related to Hess’s failure to carry out its duties as agent for the payment of such amounts as set forth above.

ARTICLE 5
