*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	On June 5, 2015 (the "Grant Date"), the reporting person was issued 18,775.27 restricted stock units ("RSUs") which shall vest in three equal, annual installments commencing June 5, 2016. Each RSU represents a contingent right to receive one share of common stock of Mack-Cali Realty Corporation (the "Company"). Dividend equivalent rights accrue with respect to these RSUs when and as dividends are paid on the Company's common stock. On July 6, 2016, the record date for the Company's quarterly dividend on its common stock (the "Dividend Record Date"), 69.64 dividend equivalent rights at $27.74 per RSU were credited to the reporting person's account.
(2)	The RSUs attributable to dividend equivalents shall vest when, and to the extent, the underlying RSUs are vested.
(3)	Reported amount includes 3,596 vested RSUs that have been settled in shares of common stock and 12,948.46 unvested RSUs (including unvested dividend equivalents with respect to such unvested RSUs).
(4)	On the Grant Date, the reporting person was granted 56,325.82 performance stock units ("PSUs") which shall vest based on the degree to which a relative total shareholder return target is attained for the three year performance period commencing on the Grant Date. Each PSU represents a contingent right to receive one share of the Company's common stock. Dividend equivalent rights accrue with respect to these PSUs when and as dividends are paid on the Company's common stock. On the Dividend Record Date, 313.39 dividend equivalent rights at $27.74 per PSU were credited to the reporting person's account.
(5)	The PSUs attributable to dividend equivalents shall vest when, and to the extent, the underlying PSUs are vested.
(6)	Reported amount excludes the following securities directly beneficially owned by the reporting person: (i) options to purchase 400,000 shares of the Company's common stock, (ii) 118,989 Class A LTIP Units of Mack-Cali Realty, L.P. (the "Operating Partnership"), and (iii) 23,041 Class B LTIP Units of the Operating Partnership. Subject to certain vesting conditions, the Class A LTIP Units and Class B LTIP Units may be converted to common units of limited partnership interest in the Operating Partnership which are redeemable for shares of common stock of the Company on a one-for-one basis.
