2.    Amendment to Section 6.10. Section 6.10 of the Contribution Agreement is hereby deleted in its entirety and replaced by the following Section 6.10:

“Section 6.10 Reimbursement of Expansion Capital Cost Overruns. EQM Gathering Opco acknowledges and agrees that following the Closing of the Asset Contribution it shall be obligated under the MPPS Gas Gathering Agreement to construct the MPPS Expansions in accordance with the terms of the MPPS Gas Gathering Agreement. EQT Gathering agrees to promptly reimburse EQM Gathering Opco for the amount by which the aggregate costs of the MPPS Expansions paid by EQM Gathering Opco (i) prior to December 31, 2017, exceeds $274,100,000 (such reimbursed amount, if any, being the “Interim Reimbursement”) and (ii) prior to December 31, 2020 (the aggregate cost as of such date being the “Final Cost”), exceeds the cumulative amount of $358,800,000; provided, that if, (i) the Final Cost is less than $358,800,000, EQM Gathering Opco shall refund to EQT Gathering the entirety of the Interim Reimbursement, (ii) the Final Cost is greater than $358,800,000 but less than the sum of $358,800,000 plus the Interim Reimbursement, EQM Gathering Opco shall refund to EQT Gathering the amount by which the Interim Reimbursement exceeds the difference of the Final Cost less $358,800,000 and (iii) the Final Cost is greater than or equal to the sum of $358,800,000 plus the Interim Reimbursement, no refund of the Interim Reimbursement is required, but the additional reimbursement in connection with the Final Cost shall be reduced by the Interim Reimbursement already paid. If construction of any of the MPPS Expansions is delayed past December 31, 2020 as a result of factors not within the control of EQM Gathering Opco, the reimbursement and refund obligations tied to such date shall be extended to ninety (90) days after the date of completion of such MPPS Expansions. For federal income tax purposes, EQM will report such payments, if any, as a purchase price adjustment in the form of a contribution to the capital of EQM or a non-pro rata distribution by EQM, as the case may be.”
