Explanation of Responses:
(1)	Each Restricted Stock Unit ("RSU") has the economic equivalent of one share of Southwestern Energy Company ("SWN") common stock. The RSUs vesting on February 26, 2020 and February 27, 2020 were settled in cash based on the closing price of SWN common stock on the vesting date.
(2)	On February 26, 2019, the reporting person was granted RSUs, vesting in four equal installments beginning on the first anniversary of the grant date, or immediately upon death, disability, retirement at age 65 with the required years of service, or a change in control. Vesting RSUs will be settled in shares of SWN common stock, cash, or a combination of shares of SWN common stock and cash.
(3)	On February 27, 2018, the reporting person was granted RSUs, vesting in four equal installments beginning on the first anniversary of the grant date, or immediately upon death, disability, retirement at age 65 with required years of service, or a change in control. Vesting RSUs will be settled in shares of SWN common stock, cash, or a combination of shares of SWN common stock and cash.
(4)	On February 26, 2020, the reporting person was granted restricted stock units, vesting in four equal installments beginning on the first anniversary of the grant date, or immediately upon death, disability, retirement at age 65 with required years of service, or a change in control. Each restricted stock unit that vests will entitle the holder to receive, payable in common stock or cash at the Compensation Committee's option, a value based on an adjusted stock price, calculated as the sum of (1) the closing stock price on the date of grant and (2) 50 percent of the difference between (a) the closing stock price on the date of vesting and (b) the closing stock price on the date of grant. If paid in stock, in no event will the number of shares of common stock delivered to the Participant exceed the number of restricted stock units granted to the participant.
