        <footnote id="F1">The reporting person elected to convert 53,944 Waiver Units  Class 3 on May 16, 2013, which comprised all of the Waiver Units of that class owned by the reporting person.  The Waiver Units  Class 3 are convertible into Common Units  Class A on a one-for-one basis, resulting in the reporting person's acquisition of a number of Common Units  Class A equal to the number of Waiver Units  Class 3 converted.</footnote>
        <footnote id="F2">The reporting person disclaims beneficial ownership of these securities, and this report shall not be deemed an admission that the reporting person is the beneficial owner of the securities for purposes of Section 16 or for any other purpose.</footnote>
        <footnote id="F3">The Waiver Units, among other rights, preferences and privileges, are entitled to quarterly distributions of $0.001786 per Waiver Unit and are convertible on a one-for-one basis at the option of the holder upon, among other things, payment of a quarterly cash distribution on the Common Units  Class A that has a coverage ratio of at least 1.10 and equals or exceeds the applicable distribution level: (i) Class 1 - $0.43 per Common Unit; (ii) Class 2 - $0.46 per Common Unit; (iii) Class 3 - $0.49 per Common Unit; and (iv) Class 4 - $0.52 per Common Unit. The Waiver Units will also automatically convert to Common Units - Class A upon the six-month anniversary of the occurrence of the circumstances that give rise to the right of the holder to convert.  The Waiver Units  Class 1 and Waiver Units  Class 2 have previously converted to Common Units  Class A. The Waiver Units  Class 3 became convertible on May 15, 2013.</footnote>
        <footnote id="F4">Waiver Units that have not become convertible by January 1, 2021 shall, as of the close of business on such date, automatically be cancelled.</footnote>
