Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Each phantom unit represents the economic equivalent of a unit representing a limited partner interest in Legacy Reserves LP.
(2)	Reflects the closing price of the units on February 16, 2018.
(3)	Phantom units granted on or after February 24, 2015 vest on February 18th in the third year after grant and are payable in units.
(4)	Pursuant to the achievement of certain objective, performance-based criteria, none of the phantom units eligible to vest for the year ended December 31, 2017, granted on February 24, 2015, vested and therefore 10,344 phantom units were forfeited. With respect to the subjective phantom unit grants, 13,578 phantom units vested.
(5)	Includes the remaining 14,674 phantom units and 14,868 phantom units from the phantom units granted on June 22, 2016 and March 1, 2017, respectively.
Remarks: Chief Accounting Officer and Controller of Legacy Reserves GP, LLC, the general partner of Legacy Reserves LP.
