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)	The holder settled 100 percent of his phantom units for RGNC common units on the date of vesting.
(2)	These common units were withheld to satisfy the applicable income and FICA tax liabilities upon the vesting of phantom units, as reported in Table II, and the vesting of 22,334 restricted common units.
(3)	These Phantom Units were granted on May 27, 2009. 6,000 of the phantom units contractually convert into a variable number of common units based on total unitholder return over a three year period or upon a change in control. This transaction represents the vesting of the original grant of 6,000 market condition phantom units multiplied by a factor of 1.5 due to a change in control event on May 26, 2010 in accordance with the terms of the grant plus the remaining 2,667 service condition phantom units.
(4)	Each Phantom Unit is the economic equivalent of one common unit representing a limited partner interest in Regency Energy Partners LP.
