already owned by the Company (treasury stock), or shares of Stock purchased for Participants in the open market, or any combination of
the foregoing.


 


6.             Administration


 


The Administrator shall be responsible
for the administration of the Plan and shall have the power in connection with such administration to interpret the Plan, to establish
rules and procedures it deems appropriate to administer the Plan, and to take such other action in connection with such administration
as it deems necessary or equitable under the circumstances. The Administrator also shall have the power to delegate the duty to perform
such administrative functions as the Administrator deems appropriate under the circumstances and any action taken in accordance with such
delegation shall be considered the action of the Administrator. Any person or management committee to whom the duty to perform an administrative
function is delegated shall act on behalf of and shall be responsible to the Administrator for such function. Any action or inaction by
or on behalf of the Administrator under the Plan shall be final and binding on each Eligible Employee, each Participant and on each other
person who makes a claim under the Plan based on the rights, if any, of any such Eligible Employee or Participant under the Plan.


 


7.             Participation


 


(a)           An
Eligible Employee may become a Participant in the Plan by submitting a properly completed Payroll Deduction Authorization to the Plan’s
recordkeeper on or before the last day of the Enrollment Period for an Offering. Unless otherwise provided by the Administrator, only
employees who are Eligible Employees on the first day of an Enrollment Period, and whose employment as an Eligible Employee continues
until the start of the related Offering, may participate in the Offering. Employment as an Eligible Employee shall not be treated as interrupted
by a transfer directly between the Company and any Designated Subsidiary which is participating in the Offering or between one Designated
Subsidiary participating in the Offering and another Designated Subsidiary participating in the same Offering.


 


(b)           A
Payroll Deduction Authorization shall require an Eligible Employee to provide such information and to take such action as the Administrator
in its discretion deems necessary or helpful to the orderly administration of the Plan, including specifying (in accordance with Section 8)
his or her Contributions to purchase shares of Stock pursuant to the Offering. Unless a Participant files a new Payroll Deduction Authorization
during a subsequent Enrollment Period, stops (or otherwise modifies) his or her Contributions in accordance with Section 8(b), or
terminates employment or otherwise ceases to be an Eligible Employee pursuant to Section 12, he or she will remain a Participant
and his or her Payroll Deduction Authorization will continue in effect at the same Contribution rate for future Offering Periods under
the Plan as long as the Plan remains in effect. The Administrator may establish procedures (applied on a uniform and nondiscriminatory
basis) for enrolling newly hired Eligible Employees or employees who otherwise become Eligible Employees during an Enrollment Period (before
the start of the related Offering Period). Otherwise, an Eligible Employee who is hired or who otherwise becomes eligible after the start
of an Enrollment Period for an Offering must wait until the Enrollment Period for the next Offering to enroll.


 






    4


     


    

 


8.             Contributions


  


(a)           Payroll
Deduction Authorization. Each Payroll Deduction Authorization made under Section 7 shall specify the Participant’s Contributions
for the Offering, which shall be a whole-number percentage of compensation (unless the Administrator determines that Contributions may
be designated as a specific dollar amount) which he or she authorizes his or her Participating Employer to deduct from his or her compensation
each pay period (as such pay period is determined in accordance with his or her Participating Employer’s standard payroll policies
and practices) during the Offering Period for which such Payroll Deduction Authorization is in effect. For each Offering, the Administrator
shall establish the definition of eligible “compensation” from which a Participant’s Contributions will be taken, which
for any Offering will be applicable to all Participants in the Offering on an identical basis. The Administrator shall determine the
elements of pay to be included in compensation for purposes of an Offering in compliance with Code Section 423 and may change the
definition on a prospective basis (provided it shall apply to Participants on an identical basis). Unless otherwise provided by the Administrator
with respect to an Offering, eligible “compensation” for purposes of each Offering under the Plan will consist of compensation
as defined in the Equitrans Midstream Corporation Employee Savings Plan, as amended and restated, but modified to exclude cash short-term
incentive payments. In general and subject to the Administrator’s determination, eligible compensation will include the Participant’s
base compensation, including overtime, and pay in lieu of vacation and exclude, among other elements, severance payments. In addition,
for any Offering, the Administrator may establish uniform rules regarding (i) required minimum Contribution levels and (ii) limitations
on the dollar amounts (or percentages of compensation) that may be contributed, provided that all such limitations shall satisfy the
requirements of Code Section 423(b)(5) with respect to any Offering. Unless otherwise provided by the Administrator with respect
to an Offering, the maximum percentage of compensation that a Participant may elect to contribute for any Offering shall equal ten percent
(10%) of the Participant’s eligible compensation per payroll period and all contribution elections shall be denominated in full
percentages.


 


(b)           Modifications.
Unless otherwise provided by the Administrator with respect to an Offering, a Participant shall have the one-time right to amend his or
her Payroll Deduction Authorization after the end of an Enrollment Period to stop the Contributions which he or she previously had authorized
for an Offering Period, in which case the accumulated Contributions through the date of such adjustment shall not be distributed to the
Participant but instead shall be used to purchase shares of Stock at the end of the Offering Period in accordance with the terms of the
Offering. Any such adjustment to a Participant’s Contributions shall be effective as soon as administratively practicable after
the Administrator receives the amended Payroll Deduction Authorization. No payroll deduction Contributions will be taken for future Offering
Periods unless the Participant submits a new Payroll Deduction Authorization during a subsequent Enrollment Period in accordance with
Section 7. Unless otherwise provided for by the Administrator with respect to an Offering, a Participant shall not otherwise have
the right to increase or decrease the Contributions which he or she previously had authorized for an Offering Period after the end of
the Enrollment Period for such Offering Period. The Administrator may establish procedures and deadlines by which Participants must make
such amendments to a Payroll Deduction Authorization.


 


(c)           Account
Credits, General Assets and Taxes. All Contributions made for a Participant shall be credited to his or her Account as soon as practicable
following the payday as of which the Contribution is made. All Contributions shall be held by the Company, by the Company’s agent
or by one, or more than one, Designated Subsidiary (as determined by the Administrator) as part of the general assets of the Company or
any such Designated Subsidiary, and each Participant’s right to the Contributions credited to his or her Account shall be those
of a general and unsecured creditor. No interest or earnings shall be credited to a Participant’s Account. All Contributions shall
be taken on an after-tax basis.


 






    5


     


    

 


9.             Granting
of Option


 


(a)           General
Rule. Subject to the remaining provisions of this Section 9, each person who is a Participant for an Offering Period automatically
shall be deemed to have been granted an Option to purchase the number of whole shares of Stock as may be purchased with the Contributions
credited to the Participant’s Account during the applicable Offering Period, subject to the limit in Section 4, if applicable,
and the Statutory Limit (as defined in Section 9(c) below). No fractional shares of Stock will be purchased; unless otherwise
provided by the Administrator, any Contributions accumulated in a Participant’s Account which are not sufficient to purchase a full
share of Stock will be retained in the Participant’s Account for the subsequent Offering, subject to earlier withdrawal in accordance
with Section 12 or as permitted by the Administrator.


 


(b)           Option
Terms. Each such Option shall be exercisable only in accordance with the terms of the Plan and the applicable Offering pursuant to
which the Option has been granted.


 


(c)           Statutory
Limitation. No Option granted under the Plan to any Eligible Employee shall permit his or her rights to purchase shares of Stock
under the Plan or under any other “employee stock purchase plan” (within the meaning of Section 423 of the Code) of
the Company or any of its Subsidiaries to accrue (within the meaning of Section 423(b)(8) of the Code) at a rate which exceeds
$25,000 of the Fair Market Value of such Stock for any calendar year (the “Statutory Limit”). Such Fair Market Value shall
be determined as of the first day of the Offering Period for which the Option is granted.


 


(d)           Insufficient
Available Shares of Stock. If the number of shares of Stock available for purchase for any Offering Period is insufficient to cover
the number of whole shares of Stock which Participants have elected to purchase, then each Participant’s Option to purchase shares
of Stock for such Offering Period shall be reduced to the number of whole shares of Stock which the Administrator shall determine by multiplying
the number of shares of Stock available for Options for such Offering Period by a fraction, the numerator of which shall be the number
of shares of Stock for which such Participant would have been granted an Option under Section 9(a) if sufficient shares of Stock
were available and the denominator of which shall be the total number of shares of Stock for which Options would have been granted to
all Participants under Section 9(a) if sufficient shares of Stock were available.


 


10.           Exercise
of Option


 


Unless a Participant terminates
employment or otherwise ceases to be an Eligible Employee pursuant to Section 12, in each case on or before the Purchase Date for
an Offering Period for which he or she has made Contributions, his or her Option shall be exercised automatically on such Purchase Date
for the purchase of as many whole shares of Stock as the balance credited to his or her Account as of that date will purchase at the Purchase
Price for such shares of Stock.


 


11.           Delivery
of Shares of Stock; Holding Period


 


Whole shares of Stock purchased
upon the exercise of an Option under the Plan may be registered in book entry form or represented in certificate form and shall be held
for the Participant in an investment account maintained by the Plan’s third-party custodian and may not be transferred from such
third-party custodian account. The shares of Stock in a Participant’s investment account shall be registered in the Participant’s
name (or, to the extent permitted under procedures established by the third-party custodian, jointly in the names of the Participant and
the Participant’s spouse or beneficiary). No Participant (or any person who makes a claim through a Participant) shall have any
interest in any shares of Stock subject to an Option until such Option has been exercised and the related shares of Stock have been registered
in the Participant’s investment account. The Administrator may impose restrictions on the sale or transfer of shares of Stock held
in a Participant’s investment account, in accordance with Code Section 423, with respect to any shares of Stock purchased under
the Plan if the purchase discount exceeds 5%.


 






    6


     


    

  


In addition, unless otherwise
provided by the Administrator, no shares of Stock purchased in any Offering under the Plan may be sold by the Participant until six (6) months
after completion of the relevant Offering Period; provided that the Participant may still direct the sale of any shares of Stock in his
or her Plan investment account during the applicable period, as long as any otherwise applicable restrictions with respect to such shares
have elapsed. Any fees associated with the sale or transfer of any shares of Stock shall be borne by the Participant.


 


12.           Termination
of Employment or Other Service; Death


 


If a Participant’s employment
with the Company or with a Designated Subsidiary terminates before the Purchase Date for an Offering Period for any reason whatsoever
(including death but in such case only if the Administrator has timely notice of such death), then his or her Account shall be distributed
to the Participant in cash (without interest) as soon as administratively practicable after the date his or her employment terminates.
If a Participant otherwise ceases to be an Eligible Employee with respect to an Offering on or before the Purchase Date with respect to
such Offering, the Participant’s aggregate Contributions for such Offering shall be distributed to the Participant in cash (without
interest) as soon as administratively practicable after the date he or she ceases to be eligible. Payment shall occur as soon as administratively
practicable (and in any event by no later than March 15th of the year following the year in which the applicable Offering Period
ends). However, if a Participant is transferred directly between the Company and a Designated Subsidiary participating in an Offering
or between one Designated Subsidiary participating in an Offering and another Designated Subsidiary participating in the same Offering,
his or her employment shall not be treated as having terminated merely because of such transfer. In the case of a leave of absence, the
Administrator shall have the authority to determine if and when a Participant’s employment has terminated in its sole discretion.


 


13.           Transferability


 


Neither the balance credited to
a Participant’s Account nor any rights to the exercise of an Option or to receive shares of Stock under the Plan may be assigned,
encumbered, alienated, transferred, pledged, or otherwise disposed of in any way by a Participant during his or her lifetime or by any
other person during his or her lifetime, and any attempt to do so shall be without effect; provided, however, that the Administrator in
its absolute discretion may treat any such action as an election by a Participant to cease future Contributions in accordance with Section 8(b).


 


14.           Adjustment


 


The number of shares of Stock
covered by outstanding Options granted pursuant to the Plan, the related Purchase Price, the number of shares of Stock available under
the Plan, the maximum limitation on shares of Stock purchasable during an Offering Period, and any other similar terms shall be adjusted
by the Board in an equitable manner to reflect any Stock split, Stock dividend or other similar change in the capitalization of the Company
without the receipt of consideration by the Company. An adjustment made under this Section 14 by the Board shall be conclusive and
binding on all affected persons.


 


15.           Amendment
or Termination


 


This Plan may be amended by the
Board from time to time to the extent that the Board deems necessary or appropriate, and any such amendment shall be subject to the approval
of the Company’s shareholders to the extent such approval is required under Section 423 of the Code, other applicable law or
stock exchange listing requirements. The Board also may terminate the Plan or any Offering made under the Plan at any time.


 






    7


     


    

 


16.           Change
of Control


 


In the event of a Change of Control,
(i) any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume
or continue outstanding Options or may substitute similar options for outstanding Options, or (ii) otherwise, all outstanding Options
under the Plan shall automatically be exercised immediately prior to the consummation of such Change of Control by causing all amounts
credited to each Participant’s Account to be applied to purchase as many shares of Stock pursuant to the Participant’s Option
as possible at the Purchase Price, subject to the limitations set forth in the Plan.


 


17.           Acquisitions
and Dispositions


 


The Administrator may, in its
sole and absolute discretion, create special Offering Periods for individuals who become Eligible Employees solely in connection with
the acquisition of a controlling interest in another company or business by a stock acquisition, merger, reorganization or purchase of
assets and, notwithstanding anything in the Plan to the contrary, may provide for special Purchase Dates for Participants who will cease
to be Eligible Employees solely in connection with the disposition of all or a portion of any Designated Subsidiary or a portion of the
Company, which Offering Periods and Purchase Dates granted pursuant thereto shall, notwithstanding anything stated herein, be subject
to such terms and conditions as the Administrator considers appropriate under the circumstances.


 


18.           Indemnity


 


The Company shall, consistent
with applicable law, indemnify members of the Administrator from any liability, loss or other financial consequence with respect to any
act or omission relating to his or her conduct in the performance of his or her duties under the Plan, except in relation to matters as
to which he or she acted fraudulently or in bad faith in the performance of such duties.


 


19.           Notices


 


All Payroll Deduction Authorizations
and other communications from a Participant to the Administrator under, or in connection with, the Plan shall be deemed to have been filed
with the Administrator when actually received in the form specified by the Administrator at the location, or by the person, designated
by the Administrator for the receipt of such authorizations and communications.


 


20.           Electronic
Forms


 


To the extent permitted by applicable
law and in the discretion of the Administrator, an Eligible Employee may submit any form or notice as set forth herein by means of an
electronic form approved by the Administrator. Before the commencement of an Offering Period, the Administrator may prescribe the time
limits within which any such electronic form shall be submitted to the Administrator with respect to such Offering Period in order to
be a valid election.


 


21.           Employment


 


No offer under the Plan shall
constitute an offer of employment, and no acceptance of an offer under the Plan shall constitute an employment agreement. Any such offer
or acceptance shall have no bearing whatsoever on the employment relationship between any Eligible Employee and the Company or any subsidiary

22.           Payment
of Expenses Related to Plan


 


The Administrator may require
that the cost, if any, for the delivery of shares of Stock to a Participant or commissions upon the sale of Stock be paid by the Participant
using such service. Other expenses associated with the Plan, if any, at the discretion of the Administrator, will be allocated as deemed
appropriate by the Administrator.


 


23.           Optionees
Not Shareholders


 


Neither the granting of an Option
to an employee, nor the deductions from his or her pay shall cause such employee to be a shareholder of the Stock covered by an Option
until such shares of Stock have been purchased by and issued to him or her.


 


24.           Taxes


 


As a condition of participating
in the Plan, a Participant shall make such arrangements as the Company or the Participating Employer may require for the satisfaction
of any applicable U.S. federal, state, local or foreign tax withholding, and any other required deductions or payments that may arise
in connection with the grant or exercise of an Option under the Plan or the sale or disposition of any shares of Stock acquired upon exercise
thereof. The Company shall not be required to issue any shares of Stock under the Plan until such obligations are satisfied. At any time,
the Company may, but shall not be obligated to, withhold from a Participant’s compensation the amount necessary for the Company
to meet applicable withholding obligations, including any withholding required to make available to the Company any tax deductions or
benefits attributable to sale or early disposition of Stock by the Participant.


 


25.           Compliance
with Applicable Law


 


No Options may be exercised to
any extent unless the shares of Stock to be issued upon such exercise under the Plan are covered by an effective registration statement
pursuant to the Securities Act of 1933, as amended, and the Plan is in material compliance with all applicable U.S. federal and state,
foreign and other securities, exchange control and other laws applicable to the Plan.
