Explanatory Note

This Amendment No. 1 to the Current Report on Form 8-K/A (the “Amendment”) is being filed as an amendment to the Current Report on Form 8-K jointly filed by Mack-Cali Realty Corporation (the “Corporation”) and Mack-Cali Realty, L.P. with the United States Securities and Exchange Commission on May 25, 2011 (the “Original Report”).  The Original 8-K was filed to report the results of the matters submitted to a vote at the Corporation’s annual meeting of stockholders held on May 24, 2011 (the “2011 Annual Meeting”). The sole purpose of this Amendment is to disclose the Corporation’s decision regarding how frequently it will conduct future, nonbinding, stockholder advisory votes on the compensation of the Corporation’s Named Executive Officers (as defined in Item 402(a) of Regulation S-K). Except for the foregoing, this Amendment does not amend, modify or update the disclosures contained in the Original 8-K.

Item 5.07. Submission of Matters to a Vote of Security Holders.

(d)                                 At the 2011 Annual Meeting, the Corporation’s stockholders voted, on a nonbinding advisory basis, on the frequency of future stockholder votes on the compensation of the Corporation’s Named Executive Officers every one, two or three years. As previously reported in the Original 8-K, 65,306,844 shares voted for one year, 99,240 shares voted for two years, 10,717,076 shares voted for three years and there were 512,512 abstentions and 5,605,623 broker non-votes.  In light of these voting results, the Corporation’s Board of Directors, at its September 14, 2011 meeting, decided that the Corporation will include a nonbinding stockholder advisory vote on Named Executive Officer compensation in the Corporation’s proxy materials every year.  The Board of Directors may, in its discretion, determine to change the frequency with which the Corporation will hold this vote.
