Notes: Net Asset Value (Unaudited) 31 The year one cap rate, applied to the Projected 2018 Cash NOI, is derived from the present value of periodic cash flows over five years and a terminal value based on stabilized income and a market cap rate, all discounted at an unlevered internal rate of return. See Information About Net Operating Income on page 33. The Company calculates estimated gross asset values for each of its operating office assets by taking the sum of (i) the present value of periodic cash flows over five years and (ii) a terminal value based on estimated stabilized income and a market capitalization rate at stabilization, all discounted at an unlevered internal rate of return. This value, divided by the projected net operating income for a one year period yields the year one imputed capitalization rate. Management projects the periodic cash flows over five years and the stabilized income from a combination of in-place lease contracts, prospective renewals of expiring leases and prospective lease-up of vacant space. Factors considered by management in projecting releasing and lease-up of vacant space and estimating the applicable market rental rates include: identification of leases currently being negotiated by management; historical annual leasing volumes for such property types; and comparable leases that have been executed for properties within the Company’s portfolio and for competitor buildings in similar locations. Reflects Projected 2018 Cash NOI for office assets; projected 12-month NOI for stabilized residential assets and the projected stabilized NOI for residential assets in development and lease-up. See Information About Net Operating Income on page 33. NAV is generally arrived at by calculating the estimated gross asset values for each of the Company’s real estate properties, investments and other significant assets and interests, and then deducting from such amounts the corresponding net debt and third parties’ interests in the assets. Gross asset values for stabilized operating multi-family real estate properties are calculated using the direct capitalization method by dividing projected net operating income for the next one year period by an estimated market capitalization rate for each property. Gross asset values for operating office properties are presented by dividing projected net operating income for the next one year period by an estimated year one imputed capitalization rate for each property. See Footnote 4 for a more detailed description of the methodology used by management to estimate gross asset values for its operating office properties. Management projects net operating income that it expects to receive for future periods from a combination of in-place lease contracts, prospective renewals of expiring leases and prospective lease-up of vacant space. Market capitalization rates are estimated for each property based on its asset class and geographic location and are based on information from recent property sale transactions as well as from publicly available information regarding unrelated third party property transactions. The value range is determined by adding or subtracting 0.50% to the year 1 cap rate for office properties and 0.25% to the year 1 cap rate for residential properties. Property cash flows have been reduced by credit loss reserves, leasing and base building capital expenditures, including Harborside renovations. The Waterfront valuation includes $80 million in capital for the Harborside renovations. Additionally, the analysis includes approximately $88 million in base building capital during the first three years of the five year discounted cash flow. The capital is allocated to physical building improvements and is estimated $40 million at the Waterfront, $28 million in the Class A Suburban, and $20 million in the Suburban portfolio’s, respectively. Furthermore, the analysis includes $10 million in leasing capital budgeted in each of the Waterfront, Class A Suburban and Suburban portfolios. This is in addition to the tenant improvements, leasing commissions and capital reserves budgeted. Valuations for non-core assets, which are those assets being considered for sale or disposal, or in the active marketing process, are generally based on recent contract prices for similar properties in the process of being sold, letters of intent and ongoing negotiations for properties. Includes the Company's ownership interests in the Hyatt Regency Jersey City and three office joint venture properties. Wegman’s $36 million asset value calculated using $1.6 million projected 2018 cash NOI capped at 4.5%. 24 Hour Fitness $20 million asset value calculated using $1 million projected cash NOI capped at 5%. See Information About Net Operating Income on page 33.

32 Notes: Net Asset Value (Unaudited) The value of land is based on a combination of recent or pending transactions for land parcels within our relevant markets and unrelated third parties, and sometimes may utilize land appraisals for certain markets, if available for other purposes, such as for transaction financing. Further, we consider what a land parcel’s value would need to be when combined with all other development costs to yield what we believe to be an appropriate target rate of return for a development project. The per apartment unit or per square foot office space values are derived by dividing the aggregate land value by the number of potential apartment units or square feet of office space the land can accommodate. The number of potential units or square feet of office space a land parcel can accommodate is most commonly governed by either in-place governmental approvals or density regulations set forth by existing zoning guidelines. Valuations for properties planned for or undergoing a repositioning or repurposing utilize a projected stabilized net operating income for the asset upon completion of the repositioning/repurposing activities. After applying an estimated capitalization rate to a projected stabilized net operating income, the capitalized value is next discounted back based on the projected number of periods to re-stabilize the asset. The discount rate applied is determined based on a risk assessment of the repositioning/repurposing activities and comparable target returns in the marketplace, and further validated by outside market sources, when available for that market. Additionally, adjustments are made to the estimated value by deducting any estimated future costs necessary to complete the planned activities, as well as adding back the discounted projected interim operating cash flows expected to be generated by the property until re-stabilization has been achieved. Joint venture investments are generally valued by: applying a capitalization rate to projected NOI for the joint venture’s asset (which is similar to the process for valuing those assets wholly owned by the Company, as described above and previously), and deducting any joint venture level debt and any value allocable to joint venture partners’ interests. Includes Roseland’s last residential subordinate interest (Metropolitan at 40 Park) and commercial subordinate interests. The valuation approach for assets in-construction or lease-up are similar to that applied to assets undergoing repositioning/repurposing, as described above. After applying an estimated capitalization rate, currently ranging from 4.5% to 5.25%, to a projected stabilized net operating income, estimated to total approximately $50.8 million upon completion of the construction or lease-up activities, the Company deducts any estimated future costs totaling $357.4 million required to complete construction of the asset to arrive at an estimated value attributable to the asset. The Company then discounts the capitalized value back based on the projected number of periods to reach stabilization. The discount rate applied, currently ranging from 7% to 9.75%, is determined based on a risk assessment of the development activities and comparable target returns in the marketplace. The Company then adds back the discounted projected interim cash flows expected to be generated during the projected lease-up period to reach stabilization. Represents the discount to stabilized value applied to assets that have not yet achieved their respective Projected Stabilized NOI due to construction, lease-up or renovation. See Information About Net Operating Income on page 33. The residential valuation analysis totals to a Roseland NAV of $1,740,000,000 and additional Mack-Cali residential holdings of $96,000,000 or an aggregate $1,836,000,000, with the company’s share of this NAV of $1,564,000,000 (“MCRC Share”). This latter amount represents the company's share of Roseland NAV, net of the $255,000,000 attributable to Rockpoint's noncontrolling interest. The increase in the approximate NAV per share of $0.49 from June 30, 2018 to September 30, 2018 is due primarily to the acquisition of Prudential’s membership interest in Marbella and improved performance at our lease-up properties. Overall, NAV is arrived at by calculating the estimated gross asset values for each of their real estate properties, investments and other significant assets and interests, and then deducting from such amounts the corresponding net debt and third parties’ interests in the assets. Gross asset values for the operating real estate properties are calculated using the direct capitalization method by dividing projected net operating income for a one year period by an estimated current capitalization rate for each property. For each operating property, management projects net operating income that it expects to receive for future periods from a combination of in-place lease contracts, prospective renewals of expiring leases and prospective lease-up of vacant space. Factors considered by management in projecting releasing and lease-up of vacant space and estimating the applicable market rental rates include: identification of leases currently being negotiated by management; historical annual leasing volumes for such property types; and comparable leases that have been executed for properties within the Registrants’ portfolio and for competitor buildings in similar locations. A capitalization rate is estimated for each property based on its asset class and geographic location. Estimates of capitalization rates are based on information from recent property sale transactions as well as from publicly available information regarding unrelated third party property transactions. The use of NAV as a measure of value is subject to certain inherent limitations. The assessment of the estimated NAV of a particular property is subjective in that it involves estimates and assumptions and can be calculated using various acceptable methods. The Company’s methods of determining NAV may differ from the methods used by other companies. Accordingly, the Company’s estimated NAV may not be comparable to measures used by other companies. As with any valuation methodology, the methodologies utilized by the Company in estimating NAV are based upon a number of estimates, assumptions, judgments or opinions that may or may not prove to be correct. Capitalization rates obtained from publicly available sources also are critical to the NAV calculation and are subject to the sources selected and variability of market conditions at the time. Investors in the Company are cautioned that NAV does not represent (i) the amount at which the Company’s securities would trade at a national securities exchange, (ii) the amount that a security holder would obtain if he or she tried to sell his or her securities, (iii) the amount that a security holder would receive if the Company liquidated its assets and distributed the proceeds after paying all of their expenses and liabilities or (iv) the book value of the Company’s real estate, which is generally based on the amortized cost of the property, subject to certain adjustments.

Information About Net Operating Income (NOI) 33 3Q 2018 NOI represents total revenues less total operating expenses, as reconciled to net income above. The Company considers NOI to be a meaningful non-GAAP financial measure for making decisions and assessing unlevered performance of its property types and markets, as it relates to total return on assets, as opposed to levered return on equity. As properties are considered for sale and acquisition based on NOI estimates and projections, the Company utilizes this measure to make investment decisions, as well as compare the performance of its assets to those of its peers. NOI should not be considered a substitute for net income, and the Company’s use of NOI may not be comparable to similarly titled measures used by other companies. The Company calculates NOI before any allocations to noncontrolling interests, as those interests do not effect the overall performance of the individuals assets being measured and assessed.
