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) Pursuant to the limited partnership agreement of Plains AAP, L.P. ("AAP"), each limited partner of AAP, other than Plains GP Holdings, L.P. ("PAGP") and Plains All American GP LLC ("GP LLC"), has the right, from time to time, to cause AAP to redeem and cancel such partner's AAP Class A units in exchange for the distribution of an equal number of common units representing limited partner interests ("Common Units") of Plains All American Pipeline, L.P. ("PAA") held by AAP (the "Redemption Right"). In connection with the exercise of a Redemption Right, such limited partner must also surrender to PAGP an equal number of Class B shares of PAGP and Company Units of PAA GP Holdings LLC ("PAGP GP").
(2) On August 16, 2017, a holder of AAP Class A units exercised the Redemption Right with respect to 300,000 AAP Class A units, resulting in the cancellation of such AAP Class A units and the distribution of 300,000 Common Units from AAP to the redeeming partner.
(3) Pursuant to that certain Omnibus Agreement (the "Omnibus Agreement") dated November 15, 2016, by and among PAGP GP, PAGP, GP LLC, AAP, PAA GP LLC and PAA, AAP is obligated to issue to PAGP a number of AAP Class A units equal to the number of PAGP Class A shares issued upon vesting of awards under PAGP's long-term incentive plan. The Omnibus Agreement also provides that immediately following such issuance, PAA is obligated to issue to AAP an equivalent number of PAA Common Units. On August 14, 2017, a total of 11,250 PAGP Class A shares were issued in connection with the vesting of outstanding LTIP awards under PAGP's long-term incentive plan. An equal number of AAP Class A units was issued to PAGP and an equal number of PAA Common Units was issued to AAP.
(4) PAGP GP is the general partner of PAGP, which is the managing member of GP LLC, which is the general partner of AAP. Each of PAGP GP, PAGP and GP LLC may be deemed to indirectly beneficially own the Common Units directly held by AAP, but disclaim beneficial ownership of such Common Units except to the extent of their respective pecuniary interests therein.
