        <footnote id="F1">The reporting person elected to convert 198,459 Waiver Units - Class 1 on February 21, 2012, which comprised all of the Waiver Units of that class owned by the reporting person. The Waiver Units - Class 1 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 1 converted.</footnote>
        <footnote id="F2">1,000 of these Common Units - Class A are held by the reporting person's father.  The reporting person disclaims beneficial ownership of these units.</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 became convertible on February 16, 2012.</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>
