Amendment of Confidentiality, Non-Solicitation and Non-Competition Agreement, dated as of November 12, 2018, by and among the Company, Equitrans Midstream Corporation and Donald M. Jenkins

THIS AMENDMENT AGREEMENT (this “Agreement”), by and among EQT Corporation, a Pennsylvania Corporation (“EQT”), Equitrans Midstream Corporation, a Pennsylvania Corporation (“Equitrans Midstream”), and Donald M. Jenkins (“Employee”), is executed as of November 12, 2018.

WHEREAS, Employee and EQT are party to an Amended and Restated Confidentiality, Non-Solicitation and Non-Competition Agreement, dated as of March 1, 2017 (the “Covenant Agreement”);

WHEREAS, Equitrans Midstream will be separated into a new publicly traded company pursuant to the Separation and Distribution Agreement, by and among EQT, Equitrans Midstream and EQT Production Company (the “Separation Agreement”) and certain other ancillary agreements;

WHEREAS, immediately prior to (and following) the separation of Equitrans Midstream into a new publicly traded company pursuant to the Separation Agreement (the “Separation”), Employee will be an employee of EQT or its subsidiaries;

WHEREAS, EQT, Equitrans Midstream and Employee have determined that, as a result of and in connection with the Separation and Employee’s employment by EQT and its subsidiaries on and immediately following the Separation, it is appropriate and in the best interests of EQT, Equitrans Midstream and Employee that certain clarifying amendments to the Covenant Agreement be adopted; and

WHEREAS, Employee acknowledges and agrees that Employee is executing this Agreement freely and of Employee’s own volition following an opportunity to consult with legal counsel of Employee’s choice.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements contained herein, and intending to be legally bound, EQT, Equitrans Midstream and Employee hereby agree as follows:

1.Effectiveness. This Agreement shall become effective upon the Effective Time (as such term is defined in the Separation Agreement). In the event that the Separation Agreement is terminated for any reason prior to the Effective Time, this Agreement shall be null and void ab initio. Except as expressly set forth herein, the Covenant Agreement shall remain in full force and effect in accordance with its terms as of the date of this Agreement.

2.    Amendment to Sections 1 and 2 of the Covenant Agreement. EQT, Equitrans Midstream and Employee each acknowledges and agrees that, if not for the Separation, the references to “the Company” in Sections 1 and 2 of the Covenant Agreement would include Equitrans Midstream as a subsidiary of EQT. In order to clarify the rights of EQT and Equitrans

Midstream on and after the Effective Time, and the obligations of Employee, under Sections 1 and 2 of the Covenant Agreement, the parties hereby agree as follows:

(a)    For purposes of Sections 1 and 2 of the Covenant Agreement, the term “the Company” shall refer to both EQT and Equitrans Midstream and their respective subsidiaries; provided, however, that (x) with respect to Equitrans Midstream and its subsidiaries, the parties agree that the post-termination non-competition and non-solicitation periods specified in Section 1 of the Covenant Agreement shall commence at the Effective Time; and (y) with respect to EQT and its subsidiaries (excluding Equitrans Midstream and its subsidiaries), the post-termination non-competition and non-solicitation periods specified in Section 1 of the Covenant Agreement shall not commence, if at all, until the date Employee’s employment with EQT and its subsidiaries terminates. For illustrative purposes only, assume (A) the Effective Time occurs on November 30, 2018 and (B) Employee’s employment with EQT and its subsidiaries terminates on March 15, 2021. In this case, by virtue of the restriction on competition for twenty-four (24) months following Employee’s termination from employment contained in Section 1 of the Covenant Agreement, the post-termination non-competition period would cease to apply (x) with respect to Equitrans Midstream and its subsidiaries, on November 30, 2020 and (y) with respect to EQT and its subsidiaries (excluding Equitrans Midstream and its subsidiaries), on March 15, 2023.

(b)    In the event that EQT and Equitrans Midstream (or their successors in interest) engage in activities that are competitive with each other, the non-competition covenant shall not apply while Employee is employed by EQT or its successor.

(c)    Equitrans Midstream shall be a third-party beneficiary of Sections 1 and 2 of the Covenant Agreement and may enforce its rights thereunder, to the same extent as EQT (as clarified by this Agreement), in accordance with Section 6 of the Covenant Agreement. Notwithstanding any provision of the Covenant Agreement to the contrary, Sections 1, 2, 6 and 11 of the Covenant Agreement may not be amended in any manner that would be adverse to the interests of Equitrans Midstream without Equitrans Midstream’s consent.

3.    Amendment to Section 3(e) of the Covenant Agreement. Section 3(e) of the Covenant Agreement is hereby amended and restated in its entirety as follows in order to provide Employee with termination protection with respect to awards granted under the Equitrans Midstream Corporation 2018 Long-Term Incentive Plan:

4.    2019 Annual Equity Awards. A condition to Employee’s eligibility for a 2019 equity award under the EQT Corporation 2014 Long-Term Incentive Plan (the “2019 LTIP Award”) is Employee’s execution of this Agreement. If Employee’s employment with EQT is terminated involuntarily by EQT without “Cause” (as defined in the Covenant Agreement) or voluntarily for “Good Reason” (as defined in the Covenant Agreement) prior to the grant to Employee of the 2019 LTIP Award, which is expected to occur on or about January 1, 2019, subject to Employee’s compliance with the Covenant Agreement (including execution and non-revocation of a release of claims), Employee shall receive a cash payment equal to the target value of the 2019 LTIP Award that would have been granted to Employee, which amount shall be paid (less applicable tax and other withholding) in a lump sum within 60 days of the termination of Employee’s employment.

IN WITNESS WHEREOF, the parties hereto have duly executed and delivered this Agreement as of the date first above written.
