12345-1-aa_final cli 2020 fight deck_page_39.jpg Bow Street’s Plan to “Streamline” Roseland Bow Street has demonstrated a clear and concerning lack of understanding of both Roseland and Rockpoint’s investment As part of its so-called three-step plan, Bow Street stated an intent to “streamline Mack-Cali’s residential assets by restructuring the Company’s residential joint venture, creating a path for a spinoff / separation at the right time” (1) (1) Bow Street Press Release (May 6, 2020). 39 (2) Per share value assumes 100.2mm common shares outstanding. Includes Rockpoint's $300mm preferred equity investment made in February 2017 and Rockpoint’s $200mm follow-on preferred equity investment made in June 2019, of which $100mm has been funded to date. Such a statement shows a lack of understanding of Rockpoint’s investment, the terms of which are public ▪ The investment is already structured to allow for the sale of Roseland or a public liquidity event ▪ Prior to March 1, 2023, a sale of Roseland or a public liquidity event would entitle Rockpoint to a prepayment penalty of up to $129mm ($1.29 per share), in addition to the return of Rockpoint’s invested capital of $400mm (2) ▪ There is no incentive for Rockpoint to modify the agreements, and in light of the prepayment penalty, any modification can be assumed to involve material costs to Mack-Cali ▪ Mack-Cali has made a significant contribution to Roseland with only $31mm of remaining equity to fund Roseland can easily be sold, but a premature separation of Roseland into a standalone entity would be destructive, highlighting the intersection of small capitalization and development focus ▪ Roseland would be highly levered and cash flow constrained from executing on its highly accretive development pipeline ▪ Such a financial profile would be detrimental to any public market valuation when viewed against publicly-traded peers Bow Street’s inability to understand the implications of the plan it advocates raises serious questions regarding its capital stewardship qualifications and its ability to maximize value for Mack-Cali shareholders

It wants to fire the CEO in the middle of a pandemic and sell the Company. Bow Street has not identified a replacement CEO for you to evaluate. It has not provided a detailed plan for how they would operate the Company that you can consider. Its interests do not align with the economic interests of our other shareholders Mack-Cali has a clear plan to maximize value for ALL shareholders ▪ The full Board, including the 4 Bow Street Directors, approved the recommendations of the Shareholder Value Committee’s strategic review, and the Special Committee is now overseeing execution of those recommendations ▪ Until a sale, the Company has the right management team in place to continue improving the value and marketability of the Company’s assets ▪ Mack-Cali intends to launch a full strategic process as soon as market conditions enable YOUR INVESTMENT IS AT STAKE.

12345-1-aa_final cli 2020 fight deck_page_50.jpg Shareholders Face a Critical Choice Mack-Cali shareholders deserve directors with the skills and independence to maximize value 50 At this critical juncture, we urge our shareholders to ask themselves two important questions: 1 )Which directors are best positioned to continue executing Mack-Cali’s ongoing strategic transformation without disruption to ensure the Company is as attractive as possible to potential bidders? 2 )Which directors will structure and execute a sale of the Company or its assets to maximize value for all Mack-Cali shareholders? Will it be the slate of conflicted nominees put forward by Bow Street ▪ a less than 5% shareholder, ▪ who previously attempted to acquire the Company’s premium assets at a lowball price under threat of a proxy contest, ▪ whose plan is to fire the CEO and sell the Company at a price that meets Bow Street’s needs, and ▪ who offers no specific new or interim CEO candidate and no substantive plan for operating the Company until a sale - OR - Will it be the slate of open-minded and shareholder-focused Mack-Cali Board nominees ▪ refreshed and reconstituted with the addition of five new highly qualified, independent and experienced nominees, ▪ who have the skillset to oversee our Company as we seek value maximizing alternatives, and ▪ the management team that designed and continues to successfully execute the Company’s ongoing portfolio transformation strategy With majority control of the Board, Bow Street can advance its own self-interested agenda at the expense of other shareholders. Can you trust them?

Mack-Cali’s Credit Facility Default Risk The publicly disclosed Credit Facility has been structured this way for nearly 20 years The Company’s unsecured revolving credit facility (the “Credit Facility”) has change of control provisions dating back to June 2000 - For purposes of the Credit Facility, the definition of a change of control includes a trigger if a majority of the seats on the Board of Directors (other than vacant seats) become occupied by directors who were neither nominated by the Board nor appointed by a majority of directors nominated by the Board, this provision protects the lender against unexpected change in the counterparty - As a result, if six or more Bow Street nominees are elected by shareholders at the Annual Meeting, this default provision of the Credit Facility may be triggered  The Company has additional Notes and Construction Loans with cross-acceleration provisions that may be triggered by a default on the Credit Facility All of the terms of these agreements have been publicly disclosed; Bow Street and the Bow Street Directors had access to this information - Bow Street, in the process of conducting their diligence to bid on the Company last year, would have become aware of this provision - Bow Street directors had full access to this information as members of the Audit Committee  Waiving the provision would require agreement from our banks, who may seek to renegotiate other terms  In the event that the provision is triggered, the Company could seek forbearance or amendment of the provisions in the event that the provision is triggered, but we have no assurance of whether that would be granted by the lender and risk is heightened by the current credit environmentWe are highlighting this provision to ensure that all shareholders are aware of this risk57
