(1) Each phantom unit represents the economic equivalent of a unit representing a limited partner interest in Legacy Reserves LP.
(2) The phantom units reported on this Form 4 vest annually in one-third increments beginning on February 18, 2014 and are payable in units or, at the discretion of the compensation committee of the board of directors of the general partner of the Issuer, in cash.
(3) The number of phantom units that vest each year for the three-year vesting period is subject to the achievement of certain objective, performance-based criteria during the fiscal year prior to the applicable vesting date. If none or only a portion of phantom units of a particular tranche vest as a result of target performance levels not being met, such number of phantom units that fail to vest will be forfeited.
(4) Includes the remaining 4,617 phantom units, 9,397 phantom units and 21,498 phantom units from the phantom units granted on February 18, 2011, February 2, 2012 and March 7, 2013, respectively.
