Explanation of Responses:
(1) The Units of Limited Partnership Interest ("Units") represent interests in
Mack-Cali Realty, L.P., a Delaware limited partnership, through which Mack-
Cali Realty Corporation conducts its real estate activities. Beginning on
December 11, 1998, the Units are redeemable for cash, based upon the fair
market value of an equivalent number of shares of Common Stock at the time
of such redemption, or, at the election of the Company, shares of Common
Stock on a one-for-one basis.
(2) Prior to September 4, 1998, 208,917 of the reporting person's 779,148 Units
beneficially owned at that time were contingent and convertible, in whole
or in part, into ordinary Units upon the satisfaction by December 11, 1999
of certain conditions relating to certain properties owned by Mack-Cali
Realty Corporation. Until such conversion, the contingent Units shall not
be entitled to any rights associated with the ordinary Units. As of
September 4, 1998, the conditions had been satisfied for the conversion of
38,143 of the reporting person's contingent Units into ordinary Units. As
of September 10, 1998, such conditions had been satisfied for the
conversion of an additional 26,620 contingent Units into ordinary Units,
and accordingly, 144,154 of the reporting persons Units remained
contingent.
(3) The Series B Preferred Units of Limited Partnership Interest (the "Series B
Preferred Units") are immediately convertible into Units. Prior to
September 10, 1998, 162 of the reporting person's 48,686 Series B Preferred
Units were contingent and convertible, in whole or in part, into ordinary
Series B Preferred Units upon the satisfaction by December 11, 1999 of
certain conditions relating to certain properties owned by Mack-Cali Realty
Corporation. Until such conversion, the contingent Series Preferred B
Units shall not be entitled to any rights associated with the ordinary
Series B Preferred Units. As of September 10, 1998, the conditions had
been satisfied for the conversion of 162 of the reporting person's
contingent Series B Preferred Units into ordinary Series B Preferred Units
and, accordingly, none of the reporting person's Series B Preferred Units
remained contingent. Currently, the reporting person's 48,686 ordinary
Series B Preferred Units are convertible into 1,405,079 Units, the 2,535
Series B Preferred Units held by the Charitable Trust are convertible into
73,160 Units and the 1,492 Series B Preferred Units held by the 4/30/92
Trust are convertible into 43,059 Units. Any Units received upon
conversion of Series B Preferred Units shall be redeemable into an equal
number of shares of Common Stock beginning on December 11, 2000.
