NOW, THEREFORE, in consideration of the mutual promises, covenants and agreements contained herein and in the GGA, the Parties hereby agree as follows:

Section 1.1    Amendments to the EQM Controlled Agreements.

(a)The Parties acknowledge and agree that, effective as of the Effective Date, each of the agreements set forth on Exhibit A-1 (the “Controlled Agreements”) shall be deemed amended as necessary to include the credit support terms set forth under Section 5.5 of the GGA (including the Minimum Credit Standard) (such terms, the “GGA Credit Support Obligations”), mutatis mutandis, other than with respect to the amount of any credit support obligation under any Controlled Agreement (which shall not be deemed amended). To the extent any adequate assurance provision or other credit support obligations set forth in any Controlled Agreement conflict with the GGA Credit Support Obligations, then the GGA Credit Support Obligations shall control to the extent of such conflict. The amendment of each Controlled Agreement under this Section 1.1(a) shall be effective until the earlier of: (i) the execution of the formal amendment of such Controlled Agreement pursuant to Section 1.1(b) and (ii) the expiration of this Letter Agreement pursuant to Section 2.2.

(b)    On or prior to March 27, 2020, the Parties shall prepare and execute (or cause their applicable affiliate(s) to execute) a formal amendment to each Controlled Agreement replacing all existing credit support obligations (other than the amount of any credit support) with the GGA Credit Support Obligations; provided that the amount of any credit support obligations as set forth in the formal amendment to each Controlled Agreement shall be reasonably determined by the Parties consistent with how the credit support amount was determined by the Parties in the GGA.

Section 1.2    Amendment to the JV Agreements. The Parties acknowledge and agree that within 15 days following the Effective Date, the Parties shall prepare an amendment to each of the agreements set forth on Exhibit A-2 (the “JV Agreements”) replacing the credit support obligations set forth in each such JV Agreement (other than the amount of any credit support obligations thereunder) with the GGA Credit Support Obligations (each, a “JV Agreement Amendment”). EQM and EQT shall each cooperate in good faith and use their commercially reasonable efforts to cause the applicable counterparties to each JV Agreement to approve and execute each of the JV Agreement Amendments on or before March 27, 2020; provided that EQT acknowledges that EQM does not control the actions of certain of the counterparties to the JV Agreements and EQM shall have no liability to EQT (other than for failure to comply with its obligations under this Section 1.2) in the event that the Parties are unable to successfully negotiate for an amendment to any of the JV Agreements in accordance with the terms of this Section 1.2.

Section 1.3    Cooperation on Amendment of MVP Credit Obligations. EQM acknowledges and agrees that concurrently with the execution of this Letter Agreement, EQM shall execute and cause its applicable subsidiaries to execute, a Letter Agreement in the form attached hereto as Exhibit C (the “MVP Letter Agreement”) amending EQT’s credit support obligations under the MVP Agreement. Following the Effective Date, EQM shall use its reasonable best efforts to cause each of the counterparties set forth in the MVP Letter Agreement to execute such MVP Letter Agreement as soon as reasonably practicable following the Effective Date or, if such counterparties refuse to sign the MVP Letter Agreement, EQM shall continue to use reasonable best efforts to cause such counterparties (including Mountain Valley Pipeline, LLC) to execute an amendment to the MVP Agreement that provides for the same credit support obligations of EQT as set forth in the MVP Letter Agreement; provided that EQT acknowledges that EQM does not control certain actions of such counterparties (including Mountain Valley Pipeline, LLC) and EQM shall have no liability (other than for failure to comply with its obligations under this Section 1.3)

to EQT in the event that the Parties are unable to successfully execute the MVP Letter Agreement or otherwise amend the MVP Agreement in accordance with the terms of this Section 1.3.

Section 1.4    Guarantees. The Parties acknowledge and agree that following the execution hereof, the guarantees set forth on Exhibit B shall remain in effect and unchanged.

Section 2.3    Governing Law; Jurisdiction.

(a)    This Letter Agreement shall be governed by, construed, and enforced in accordance with the laws of the Commonwealth of Pennsylvania without regard to choice of law principles.

(b)    The Parties agree that the appropriate, exclusive and convenient forum for any disputes among any of the Parties arising out of this Letter Agreement or the transactions contemplated hereby shall be in any state or federal court in the City of Pittsburgh and County of Allegheny, Pennsylvania, and each of the Parties irrevocably submits to the jurisdiction of such courts solely in respect of any proceeding arising out of or related to this Letter Agreement. The Parties further agree that the Parties shall not bring suit with respect to any disputes arising out of this Letter Agreement or the transactions contemplated hereby in any court or jurisdiction other than the above specified courts.

NOTWITHSTANDING ANYTHING IN THIS LETTER AGREEMENT TO THE CONTRARY, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR SPECIAL, INDIRECT, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES SUFFERED BY SUCH PARTY RESULTING FROM OR ARISING OUT OF THIS LETTER AGREEMENT OR THE BREACH THEREOF OR UNDER ANY OTHER THEORY OF LIABILITY, WHETHER TORT, NEGLIGENCE, STRICT LIABILITY, BREACH OF CONTRACT, WARRANTY, INDEMNITY OR OTHERWISE, INCLUDING LOSS OF USE, INCREASED COST OF OPERATIONS, LOSS OF PROFIT OR REVENUE, OR BUSINESS INTERRUPTIONS.

Section 2.5    Counterpart Execution. This Letter Agreement may be executed in any number of counterparts, each of which shall be considered an original, and all of which shall be considered one and the same instrument.
