| | <footnote id="F1"> Effective on February 28, 2020, EPD PubCo Unit I L.P. ("EPD PubCo I") was liquidated in accordance with its agreement of limited partnership. Upon EPD PubCo I's liquidation, the reporting person's Class B limited partner interest in EPD PubCo I automatically converted into the right to receive 18,296 common units representing limited partnership interests in the issuer ("Common Units"), based on the reporting person's percentage share of Class B limited partner interests in EPD PubCo I immediately prior to the liquidation. After giving effect to the distributions related to the liquidation of EPD PubCo I, the reporting person no longer has any interest in EPD PubCo I. </footnote> |
