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. Prior to September 10, 1998, 17,403 of the
reporting person's 18,071 Units 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 10, 1998, the conditions had been satisfied for the conversion of
9,069 of the reporting person's contingent Units into ordinary Units, and
accordingly, 8,334 of the reporting person's Units remained contingent.
(2) The Series B Preferred Units of Limited Partnership Interest (the "Series B
Preferred Units") are immediately convertible into Units. Prior to
September 10, 1998, 47 of the reporting person's 957 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 B Preferred
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 47 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 957 Ordinary Series
B Preferred Units are convertible into 27,619 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.
