        <footnote id="F1">Pursuant to the limited partnership agreement of Plains AAP, L.P. (&quot;AAP&quot;), EMG Investment, LLC (&quot;EMG&quot;) has the right, at any time and from time to time, to redeem its Class A Units in AAP (&quot;Class A Units&quot;) for common units (&quot;Common Units&quot;) of Plains All American Pipeline, L.P. (the &quot;Issuer&quot;) held by AAP on a one-for-one basis, by delivering such Class A Units to AAP along with the associated Class B shares (&quot;Class B Shares&quot;) in Plains GP Holdings, L.P. (&quot;PAGP&quot;) and GP Units (&quot;GP Units&quot;) in PAA GP Holdings LLC to PAGP (the &quot;Redemption Right&quot;). Pursuant to the limited partnership agreement of AAP, the Redemption Right does not expire.</footnote>
        <footnote id="F2">On November 18, 2020, in lieu of exercising its Redemption Right, EMG elected to exercise its right, pursuant to the limited partnership agreement of AAP, to immediately exchange 6,220,955 Class A Units, together with a like number of Class B Shares and GP Units, for Class A shares (&quot;Class A Shares&quot;) in PAGP on a one-for-one basis. EMG has agreed to sell the Class A Shares received pursuant to such election to exchange in a single transaction exempt from registration under Rule 144 of the Securities Act of 1933, as amended, at a price of $8.05 per Class A Share. Following the completion of such sale, EMG will distribute the proceeds thereof to its remaining members on a pro rata basis.</footnote>
        <footnote id="F3">Beneficial ownership of the Class A Units, Class B Shares and GP Units referred to herein is being reported hereunder by NGP MR Management, LLC solely because NGP MR Management, LLC may be deemed to beneficially own such Class A Units, Class B Shares and GP Units as a result of its status as the designated manager of EMG. NGP MR Management, LLC disclaims beneficial ownership of the securities held by EMG except to the extent of its pecuniary interest therein.</footnote>

    <remarks>John T. Raymond previously served as the representative of EMG Investment, LLC on the board of directors of the general partner of the Issuer (the &quot;Board&quot;). In May 2019, as a result of a series of transactions pursuant to which EMG's ownership interest in AAP was reduced to below the 10% requisite qualifying interest level, EMG lost its right to designate a representative to serve on the Board, and is therefore no longer subject to Section 16. As a result of EMG's loss of its designation right, Mr. Raymond, EMG's designee to the Board, automatically ceased to be a member of the Board. Mr. Raymond was subsequently elected to continue to serve on the Board.
Mr. Raymond is the Chief Executive Officer of The Energy &amp; Minerals Group which is the management company for a series of specialized private equity funds including NGP Midstream &amp; Resources, L.P. and is the Chief Executive Officer of NGP MR Management, LLC, which is the manager of EMG Investment, LLC. As such, EMG Investment, LLC and NGP MR Management, LLC may each be deemed to have been a director of the Issuer prior to May 2019. The filing of this Statement shall not be construed as an admission that any Reporting Person is, for purposes of Section 13(d) of the Securities and Exchange Act of 1934, as amended, the beneficial owner of any security.</remarks>
