As such, each of Admin and Admin GP may be deemed to beneficially own the Class B Shares, AAP Units and GP Units held by Investment. Each of Admin and Admin GP disclaims beneficial ownership of the securities held by Investment except to the extent of their pecuniary interest therein, which interest is a significant pecuniary interest.
(2) The Class B Shares, GP Units and AAP Units are collectively exchangeable for Class A shares representing limited partner interests in the Issuer (the "Class A Shares"). In connection with the closing of the initial public offering of the Issuer (the "Offering"), the limited partnership agreement of Plains AAP, L.P. was amended and restated to provide that each limited partner of AAP, including Investment, will have the right, at any time and from time to time, to immediately exchange (the "Exchange Right") its AAP Units, together with a like number of Class B Shares and GP Units, for Class A Shares on a one-for-one basis. The Exchange Right does not expire and may be settled in cash at the option of AAP. As such, Investment, Admin and Admin GP may not be deemed to beneficially own the Class A Shares reported herein for purposes of Section 13d.
(3) Investment beneficially owned the AAP Units prior to the consummation of the Offering.
