BOW STREET BAFFLED BY MACK-CALI CHAIRMAN WILLIAM MACK’S

RASH TERMINATION OF SETTLEMENT DISCUSSIONS

NEW YORK – May 17, 2019 – Bow Street LLC ("Bow Street"), a New York-based investment firm that beneficially owns approximately 4.5% of the outstanding shares of common stock of Mack-Cali Realty Corporation (“Mack-Cali” or the “Company”) (NYSE: CLI), today sent a letter to Mack-Cali Chairman William Mack expressing Bow Street’s concern at his abrupt termination of settlement discussions.

May 17, 2019

Dear Mr. Mack,

Over the past week, we engaged in several conversations which we believed to be constructive and would result in a fair and straightforward resolution of our ongoing proxy contest. As such, we were pleased when you sent us a Settlement Agreement calling for the establishment of a Strategic Review Committee of the Board, comprised of two Bow Street nominees and two Mack-Cali incumbent directors, with a mandate to review the Company’s strategic direction and explore the value to be realized from a sale of the Company or any of its assets.

Our comments to the Settlement Agreement were entirely within the spirit of our discussions and only clarified the Strategic Review Committee’s ability to independently evaluate the best path forward for Mack-Cali. We were therefore surprised that following receipt of our comments, you called this morning to simply inform us that our changes did not work. Before giving us a moment to speak, you abruptly hung up the phone, only to call us back a moment later and hang up the phone again.

We believe our comments were in the best interests of shareholders. They included:

Bow Street and Mack-Cali agreeing in advance to the directors that would comprise the Strategic Review Committee;

Enabling the Strategic Review Committee to engage an investment bank instead of a valuation firm, which we believe would be better positioned to determine the value that could be expected to be received in a strategic transaction as compared to the value of the Company on a standalone basis; and

In the event that Mack-Cali receives any unsolicited proposals, providing the Special Review Committee with a mandate to review such proposals.

We hope to continue settlement discussions on the good faith terms with which we initiated them, premised on the establishment of a Strategic Review Committee with the resources, independence, and mandate to determine the best path forward for Mack-Cali and its shareholders.

Respectively,

Akiva Katz Howard Shainker
