Footnote F2

Performance-based units representing the right to receive common units, together with tandem distribution equivalent rights, were awarded in February 2023 under the issuer's LTIP.

Accrued quarterly distributions made during the vesting period were paid in cash to the reporting person on the reporting date.

Footnote F3

Phantom units representing the right to receive common units on a one-for-one basis, together with tandem distribution equivalent rights, were awarded in February 2023 under the issuer's LTIP. One-third of the phantom units vested on the third anniversary of the grant date and converted into common units on the reporting date. Accrued quarterly distributions made during the vesting period were paid in cash to the reporting person on the reporting date.

Footnote F4

Phantom units representing the right to receive common units on a one-for-one basis, together with tandem distribution equivalent rights, were awarded in February 2024 under the issuer's LTIP.
