(1) 1. On March 22, 2019, the reporting person received a grant of Class G 2019 LTIP Units (the "Class G Units") of Mack-Cali Realty, L.P. (the "Operating Partnership"). The Class G Units are a class of units of the Operating Partnership that, following the occurrence of certain events and upon vesting are convertible by the holder into an equivalent number of Common Units of the Operating Partnership ("Common Units"). Common Units of the Operating Partnership are redeemable by the holder for cash or, at the election of Mack-Cali Realty Corporation (the "Company"), shares of common stock of the Company on a one-for-one basis or the cash value of such shares.
(2) Fifty percent (50%) of the Class G Units may vest over a three to five year period based on the attainment of absolute total stockholder return ("TSR") metrics by the Company over a three year performance period. The remaining fifty percent (50%) of the Class G Units may vest over a three to five year period based on the Company's TSR relative to the TSR of other equity office REITs in the NAREIT Index over the same three year performance period.
(3) On March 22, 2019, the reporting person received a grant of Class H 2019 LTIP Units (the "Class H Units") of the Operating Partnership. The Class H Units are a class of units of the Operating Partnership that, following the occurrence of certain events and upon vesting are convertible by the holder into an equivalent number of Common Units. Common Units of the Operating Partnership are redeemable by the holder for cash or, at the Company's election, shares of common stock of the Company on a one-for-one basis or the cash value of such shares.
(4) The Class H Units vest on March 22, 2022 and are not subject to expiration.
(5) Reported amounts exclude the following securities directly beneficially owned by the reporting person: (i) 17,007 Class E 2018 LTIP Units of the Operating Partnership, and (ii) 8,850 Class F 2018 LTIP Units of the Operating Partnership. Subject to certain vesting conditions, all of these other classes of LTIP Units of the Operating Partnership may be converted to Common Units on a one-for-one basis.
