F1 · ownership.direct: Includes 7,500 units held jointly with Reporting Person's spouse.

F2 · ownership.direct: In February 2020, the reporting person and his spouse received 2,784 and 2,785 common units of PAA, respectively, in a distribution from their respective grantor retained annuity trusts in accordance with the terms of the GRATs. The distribution of units from the GRATs resulted in a decrease in the number of units beneficially owned indirectly through the GRATs, and a corresponding increase in the number of units beneficially owned directly and indirectly through spouse. The distribution of units from the GRATs constituted a change in form of beneficial ownership, which is exempt under Rule 16a-13 of the Exchange Act.
