This SECONDMENT AGREEMENT (“Agreement”) is dated as of [·], 2018 (the “Effective Date”) by and among Equitrans Midstream Corporation, a Pennsylvania corporation (“ETRN”), EQM Midstream Partners, LP, a Delaware limited partnership (the “Partnership”), and EQM Midstream Services, LLC, a Delaware limited liability company and the general partner of the Partnership (“General Partner”).  ETRN, the Partnership and the General Partner may be referred to herein individually as “Party” or collectively as “Parties.”

RECITALS

WHEREAS, the Partnership, the General Partner and ETRN, are parties to that certain Omnibus Agreement (as amended from time to time, the “Omnibus Agreement”) dated as of the date hereof, which provides for, among other things, the provision by ETRN of certain corporate, general and administrative services to the Partnership and its subsidiaries (the “Partnership Group”);

WHEREAS, certain members of the Partnership Group (each an “Owner”) own or lease natural gas pipelines, including natural gas gathering and transmission systems, compressors, storage and other related facilities, and water lines and related equipment and facilities; and

WHEREAS, the Parties desire by their execution of this Agreement to evidence their understanding, as more fully set forth in Article 2, with respect to the secondment of employees for the provision of certain operation and management services by the ETRN Group (as defined below) for and on behalf of the Partnership Group and the Partnership’s obligations related thereto.

NOW THEREFORE, in consideration of their mutual undertakings and agreements hereunder, the Parties undertake and agree as follows:

ARTICLE 1
DESCRIPTION OF FACILITIES

1.1Facilities Description.  “Facilities” means all facilities, pipelines (including natural gas, natural gas liquid and water pipelines), machinery, measurement equipment (including vehicles) and other equipment, accessions and improvements in respect of the foregoing, now or hereafter owned or leased by a member of the Partnership Group, unless ETRN and the Partnership determine to exclude any such assets from being subject to this Agreement (such excluded assets, “Excluded Facilities”).

ARTICLE 2
SECONDMENT OF EMPLOYEES

2.1Seconded Employees.  Subject to the terms of this Agreement, ETRN agrees to second, or cause to be seconded, respectively, those available employees of any of ETRN and its affiliates (other than the General Partner, the Partnership and its subsidiaries) (the “ETRN Group”) for the purpose of providing services (“Services”) with respect to the assets of any Owner from time to time (the “Seconded Employees”) to such Owner, and such Owner agrees to accept each assignment of any Seconded Employees to the Owner from ETRN in accordance with the terms

of this Agreement (a “Secondment”) for the purpose of performing the Services with respect to the Facilities.  The Seconded Employees will remain at all times the employees of the applicable ETRN Group member, and, in addition, they will also be temporary co-employees of the applicable Owner during the Period of Secondment (as defined below) and shall, at all times during the Period of Secondment, work under the direction, supervision and control of the Owner related to the Facilities.  Seconded Employees shall have no authority or apparent authority to act on behalf of any ETRN Group member during the Period of Secondment related to the Facilities.  The 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 individuals from the group of Seconded Employees to the extent necessary to enforce such rights and obligations.

2.2Duties and Authority of Seconded Employees.  Under the direction of the applicable Owner, the Seconded Employees shall, subject to the terms of this Agreement, perform duties for the operation, maintenance, repair, design, alteration and replacement of the Facilities and of the business processes associated with the Facilities.

ARTICLE 3
TERMS OF SECONDMENT

3.1Independent Contractor.  ETRN is an independent contractor and, upon the reasonable request by an Owner and subject to the availability of employees to second, shall second, or cause to be seconded, the Seconded Employees as an independent contractor. Nothing hereunder shall be construed as creating any other relationship among the Parties, including but not limited to a partnership, agency or fiduciary relationship, joint venture, limited liability company, association, or any other enterprise. Except to the extent provided in Section 2.1, none of the Parties or any of their employees shall be deemed to be an employee of another Party.

3.2Period of Secondment.  ETRN will second, or cause to be seconded, the Seconded Employees to the applicable Owner starting on the Effective Date and continuing, during the period (and only during the period) that the Seconded Employees are performing Services for such Owner, until the earlier of:

(a)the end of the term of this Agreement;

(b)such end date for any Seconded Employees as may be mutually agreed by ETRN and the applicable Owner (the “End Date”);

(c)a withdrawal, departure, resignation or termination of such Seconded Employees under Section 3.3; or

(d)a termination of Secondment of such Seconded Employees under Section 3.4.

The period of time that any Seconded Employee is provided by ETRN to an Owner 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 such Owner of the Seconded Employee’s day-to-day activities.  The Parties acknowledge that certain of the Seconded Employees may also provide services to the ETRN

2

Group in connection with operations conducted by the ETRN Group (“Shared Seconded Employees”) and the Parties intend that such Shared Seconded Employees shall only be seconded to the applicable Owner during those times that the Shared Seconded Employees are performing Services for such Owner hereunder.

3.3Withdrawal, Departure or Resignation.  If any Seconded Employee tenders his or her resignation to an applicable ETRN Group member, or if the employment of any Seconded Employee is terminated by an applicable ETRN Group member, ETRN will promptly notify the applicable Owner.  During the Period of Secondment of any Seconded Employee, the applicable ETRN Group member will not voluntarily withdraw or terminate such Seconded Employee except under Section 3.4 or with the consent of the applicable Owner, which consent shall not be unreasonably withheld, conditioned or delayed.

3.4Termination of Secondment.  Subject to any restrictions contained in any collective bargaining agreement to which an ETRN Group member is a party, the applicable Owner will have the right to terminate the Secondment to such Owner of any Seconded Employee for any reason at any time.  ETRN will not, without the applicable Owner’s express consent, agree to any future amendments to any collective bargaining agreement that would increase the type or degree of any limitations on the Owner’s ability to terminate the Secondment of any Seconded Employee. In addition, any member of the ETRN Group shall have the right at any time and from time to time to terminate the Secondment of any Seconded Employee by providing a substitute Seconded Employee.  Upon the termination of any Seconded Employee’s Period of Secondment, ETRN 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.

3.5Supervision.  During the Period of Secondment, the applicable Owner shall:

(a)be ultimately and fully responsible for the daily work assignments of the Seconded Employees (and with respect to Shared Seconded Employees, during those times that the Shared Seconded Employees are performing Services for the Owner hereunder), including supervision of their day-to-day work activities and performance consistent with the job functions associated with the Services;

(b)have the right to set the hours of work and the holidays and vacation schedules (other than with respect to Shared Seconded Employees, as to which the Owner and ETRN shall jointly determine) for Seconded Employees; and

(c)have the right to determine training which will be received by the Seconded Employees.

The Partnership, for itself and on behalf of each Owner, agrees that with respect to any Seconded Employee who is otherwise represented by a union while working for the ETRN Group, the Owner will be assigned the applicable ETRN Group member’s rights and responsibilities of any applicable collective bargaining agreement for the Period of Secondment as to any such employee, subject to any changes agreed to between the applicable ETRN Group member and any applicable union or as may be allowed by law.  The Owner is not, hereby, agreeing to recognize

3

any union or assume any bargaining obligation.  Any and all recognition and bargaining obligations, to the extent that they exist, will remain with the applicable ETRN Group member.

3.6Seconded Employees Qualifications; Approval.  ETRN will provide such suitably qualified and experienced Seconded Employees as ETRN is reasonably able to make available to the Partnership, and the applicable Owner 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 applicable Owner as suitable for performing job functions related to the Services.

3.7Workers Compensation.  At all times, the ETRN Group will maintain workers’ compensation insurance (either through an insurance company or approved self-insurance arrangement) applicable to the Seconded Employees, and will include each Owner as an Alternate Employer under each applicable insurance policy.  The Parties agree that a Seconded Employee’s sole remedy for any workplace injury suffered during the Period of Secondment shall be under the workers’ compensation insurance (either through an insurance company or approved self-insurance arrangement) applicable to the Seconded Employees.

3.8Benefit Plans.  No Owner nor any member of the Partnership Group shall be a participating employer in any Benefit Plan (as defined below) during the Period of Secondment.  Subject to the applicable Owner’s reimbursement obligations hereunder, the ETRN Group 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 terms and conditions, as they may be amended from time to time. ETRN and its ERISA Affiliates (as defined below) may amend or terminate any Benefit Plan 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 Owner nor any other member of the Partnership Group 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.

For the purposes of this Section 3.8, “Benefit Plans” means each employee benefit plan, as defined in Section 3(3) of The Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and any other material plan, policy, program, practice, agreement, understanding or arrangement (whether written or oral) providing compensation or other benefits to any Seconded Employee (or to any dependent or beneficiary thereof), including, without limitation, any stock bonus, stock ownership, stock option, stock purchase, stock appreciation rights, phantom stock, restricted stock or other equity-based compensation plans, policies, programs, practices or arrangements, and any bonus or incentive compensation plan, deferred compensation, profit sharing, holiday, cafeteria, medical, disability or other employee benefit plan, program, policy, agreement or arrangement sponsored, maintained, or contributed to by the applicable ETRN Group member or any entity that would be treated as a single employer with ETRN or the ETRN Group member under Sections 414(b), (c) or (m) of the Code or Section 4001(b)(1) of ERISA (“ERISA Affiliates”), or under which ETRN, the ETRN Group member, or any ERISA Affiliate may have any obligation or liability, whether actual or contingent, in respect of or for the benefit of any Seconded Employee (but excluding workers’ compensation benefits (whether through insured or self-insured arrangements) and directors and officers liability insurance).

ARTICLE 4
REIMBURSEMENT AND BILLING PROCEDURES

4.1Reimbursement.  Except as provided below in Sections 4.3, 4.4 and 4.5, the applicable Owner shall reimburse ETRN for the secondment of the Seconded Employees pursuant to this Agreement in the same manner that the Partnership reimburses ETRN pursuant to the reimbursement for services provisions of the Omnibus Agreement (“Services/Secondment Reimbursement”).

4.2Billing Procedures.  ETRN shall invoice the applicable Owner for the Seconded Employees in accordance with the billing procedures provisions of the Omnibus Agreement.

4.3Adjustments Based on Period of Secondment.  It is understood and agreed that the applicable Owner shall be liable for wages and other costs associated with a Seconded Employee (“Seconded Employee Expenses”) to the extent, and only to the extent, they are attributable to the Period of Secondment.   As such, if the Period of Secondment begins on other than the first day of a month or ends on other than the last day of a month, the Seconded Employee Expenses for such month shall be prorated based on the number of days during such month that the Period of Secondment was in effect.

4.4Adjustments for Shared Services. With respect to each Shared Seconded Employee, ETRN will determine in good faith the percentage of such Shared Seconded Employee’s time spent providing Services to the applicable Owner (the “Allocation Percentage”). For each month during the Period of Secondment, the amount of the Services Reimbursement payable by the applicable Owner with respect to each Shared Seconded Employee shall be calculated by multiplying the Seconded Employee Expenses for such Shared Seconded Employee times the Allocation Percentage for such Shared Seconded Employee; provided, however, that certain Second Employee Expenses shall not be allocated based on the Allocation Percentage but rather shall be allocated as follows:

(a)termination costs with respect to any Shared Seconded Employee shall be allocated between the applicable Owner and the ETRN Group based upon the Allocation Percentage, provided that the Owner and ETRN or the applicable ETRN Group member agree in advance to terminate such Shared Seconded Employee; otherwise, a Party who terminates a Shared Seconded Employee without first consulting with the other Party or applicable affiliate (including an actual or alleged constructive termination) shall be solely responsible for all termination costs related to such termination, other than any termination costs arising solely out of the gross negligence or willful misconduct of the other Party or applicable affiliate;

(b)travel expenses and other expenses incurred with respect to and/or reimbursable to a Shared Seconded Employee shall be paid by the Party for whom the Shared Seconded Employee was working at the time they were incurred, except that expenses related to activities that benefit both the applicable Owner and the ETRN Group (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); and

5

(c)any sales taxes imposed upon the provision of any taxable Services provided under this Agreement shall be reimbursable in full by the applicable Owner, provided that the Owner and ETRN contemplate that the Services provided pursuant to this Agreement are not taxable services for sales and use tax purposes.

ARTICLE 5
TERMINATION

5.1Termination.  This Agreement will terminate automatically upon the termination of the Omnibus Agreement.  Upon termination of this Agreement, all rights and obligations of the Parties under this Agreement shall terminate, provided, however, that such termination shall not affect or excuse the performance of any party under the provisions of Article 6, which provisions shall survive the termination of this Agreement indefinitely.

ARTICLE 6
INDEMNITY

6.1Indemnification Scope.  IT IS IN THE BEST INTERESTS OF THE PARTIES THAT CERTAIN RISKS RELATING TO THE MATTERS GOVERNED BY THIS AGREEMENT SHOULD BE IDENTIFIED AND ALLOCATED AS AMONG THEM. IT IS THEREFORE THE INTENT AND PURPOSE OF THIS AGREEMENT TO PROVIDE FOR THE INDEMNITIES SET FORTH HEREIN TO THE MAXIMUM EXTENT ALLOWED BY LAW. ALL PROVISIONS OF THIS ARTICLE SHALL BE DEEMED CONSPICUOUS WHETHER OR NOT CAPITALIZED OR OTHERWISE EMPHASIZED.

6.2Indemnified Persons.  Wherever “ETRN” appears as an Indemnitee in this Article, the term shall include that entity, its parents, subsidiaries, affiliates, partners, members, contractors and subcontractors at any tier, and the respective agents, officers, directors, employees, and representatives of the foregoing entities involved in actions or duties to act on behalf of the indemnified party (collectively, the “ETRN Indemnitees”); provided, however, that the ETRN Indemnitees shall not include the Owners, the General Partner or the Partnership. As used in this Article 6, references to “third parties” shall not include any ETRN Indemnitees.

6.3Indemnification. THE OWNERS SHALL RELEASE, DEFEND, INDEMNIFY, AND HOLD HARMLESS THE ETRN INDEMNITEES FROM AND AGAINST ANY AND ALL CLAIMS, CAUSES OF ACTION, DEMANDS, LIABILITIES, LOSSES, DAMAGES, FINES, PENALTIES, JUDGMENTS, EXPENSES AND COSTS, INCLUDING REASONABLE ATTORNEYS’ FEES AND COSTS OF INVESTIGATION AND DEFENSE (EACH, A “LIABILITY”) (INCLUDING, WITHOUT LIMITATION, ANY LIABILITY FOR (A) DAMAGE, LOSS OR DESTRUCTION OF THE FACILITIES, (B) BODILY INJURY, ILLNESS OR DEATH OF ANY PERSON, AND (C) LOSS OF OR DAMAGE TO EQUIPMENT OR PROPERTY OF ANY PERSON) ARISING FROM OR RELATING TO THIS AGREEMENT.

6.4Damages Limitations.  Any and all damages recovered by a Party pursuant to this Article 6 or pursuant to any other provision of or actions or omissions under this Agreement shall be limited to actual damages. CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT

6

LIMITATION BUSINESS INTERRUPTIONS AND LOST PROFITS) AND EXEMPLARY AND PUNITIVE DAMAGES SHALL NOT BE RECOVERABLE UNDER ANY CIRCUMSTANCES EXCEPT TO THE EXTENT THOSE DAMAGES ARE INCLUDED IN THIRD PARTY CLAIMS FOR WHICH A PARTY HAS AGREED HEREIN TO INDEMNIFY THE OTHER PARTY. EACH PARTY ACKNOWLEDGES IT IS AWARE THAT IT HAS POTENTIALLY VARIABLE LEGAL RIGHTS UNDER COMMON LAW AND BY STATUTE TO RECOVER CONSEQUENTIAL, EXEMPLARY, AND PUNITIVE DAMAGES UNDER CERTAIN CIRCUMSTANCES, AND EACH OF THE PARTIES NEVERTHELESS WAIVES, RELEASES, RELINQUISHES, AND SURRENDERS RIGHTS TO CONSEQUENTIAL PUNITIVE AND EXEMPLARY DAMAGES TO THE FULLEST EXTENT PERMITTED BY LAW WITH FULL KNOWLEDGE AND AWARENESS OF THE CONSEQUENCES OF THE WAIVER REGARDLESS OF THE NEGLIGENCE OR FAULT OF EITHER PARTY.

6.5Defense of Claims.  The indemnifying Party shall defend, at its sole expense, any claim, demand, loss, liability, damage, or other cause of action within the scope of the indemnifying Party’s indemnification obligations under this Agreement, provided that the indemnified Party notifies the indemnifying Party promptly in writing of any claim, loss, liability, damage, or cause of action against the indemnified Party and gives the indemnifying Party authority, information, and assistance at the reasonable expense of the indemnified Party in defense of the matter. The indemnified Party may be represented by its own counsel (at the indemnified Party’s sole expense) and may participate in any proceeding relating to a claim, loss, liability, damage, or cause of action in which the indemnified Party or both Parties are defendants, provided, however, that the indemnifying Party shall, at all times, control the defense and any appeal or settlement of any matter for which it has indemnification obligations under this Agreement so long as any such settlement includes an unconditional release of the indemnified Party from all liability arising out of such claim, demand, loss, liability, damage, or other cause of action and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of the indemnified Party.  Should an Owner and ETRN both be named as defendants in any third-party claim or cause of action arising out of or relating to the Facilities or Services, the Parties will cooperate with each other in the joint defense of their common interests to the extent permitted by law, and will enter into an agreement for joint defense of the action if the Parties mutually agree that the execution of the same would be beneficial.
