Item 3.02            Unregistered Sales of Equity Securities.

On February 3, 2017 (the “Closing Date”), Mack-Cali Realty, L.P. (the “Operating Partnership”), the operating partnership of Mack-Cali Realty Corporation (the “General Partner”), issued 42,800 shares of a new class of 3.5% Series A Preferred Limited Partnership Units of the Operating Partnership (the “Preferred Units”). The Preferred Units were issued in reliance upon the exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, to sophisticated real estate investors who were  partners in a joint venture with the Operating Partnership that owns a development site (known as Plaza VIII & IX) adjacent to its Harborside property in Jersey City, New Jersey as consideration for their approximate 37.5 percent interest in the joint venture. Concurrent with the issuance of the Preferred Units, the Operating Partnership purchased from other partners in the same joint venture their approximate 12.5 percent interest for approximately $14.3 million in cash.  The results of these transactions increased the Operating Partnership’s interests in the joint venture from 50 percent to 100 percent.

Each Preferred Unit has a stated value of $1,000 (the “Stated Value”), pays dividends quarterly at an annual rate equal to the greater of (x) 3.5%, or (y) the then-effective annual dividend yield on the General Partner’s common stock, and is convertible into 28.15 common units of limited partnership interests of the Operating Partnership (“Common Units”) beginning generally five years from the date of issuance, or an aggregate of up to 1,204,820 Common Units. The conversion rate for the Preferred Units was based on a value of $35.52 per Common Unit, which was 125 percent of the five day trading average of the General Partner’s common stock ending three days before the Closing Date.  The Preferred Units have a liquidation and dividend preference senior to the Common Units and include customary anti-dilution protections for stock splits and similar events.  The Preferred Units are redeemable for cash at their Stated Value beginning five years from the date of issuance at the option of the holder.

A copy of the Certificate of Designation for the Preferred Units dated February 3, 2017 is filed as Exhibit 3.1 hereto and incorporated herein by reference.

Item 5.03             Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.
