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 Class B Units in Plains AAP, L.P. represent a profits interest. The Class B Units become earned (entitled to receive distributions) in 25% increments upon payment by Plains All American Pipeline, L.P. ("PAA") of annualized quarterly distributions of $2.90, $3.15, $3.30 and $3.50 per PAA common unit, respectively. The Class B Units are subject to a call right in the event Reporting Person's employment is terminated under certain circumstances prior to December 31, 2022. If Reporting Person remains employed after such date or his employment is terminated under certain circumstances prior to December 31, 2018, the Class B Units will be deemed to have vested.
(2) After December 31, 2015, Reporting Person has the right to convert his vested Class B Units into a number of Class A Units in Plains AAP, L.P. and Class B Shares in Plains GP Holdings, L.P. equal to the number of Class B Units converted times a conversion factor (which conversion factor will not be more than 1:1 and was approximately 0.937:1 as of the date hereof). Following any such conversion, the resulting Class A Units and Class B Shares are exchangeable for Class A Shares of PAGP on a one-for-one basis.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
