Financial Highlights– Evolving Portfolio with Superior Quality of Earnings Mack-Cali has continued to transform its portfolio from heavily suburban earnings towards a growing Residential and specifically geographically focused office(1) concentration As a percentage of Net Operating Income, the combined contributions from the residential and focused office platforms are projected to increase from 48% in 2016 to 70% in 2018 Incorporating stabilized NOI in our 2,300 unit In-Construction portfolio of $53 million, the percentage of NOI from our Residential and geographically focused office categories are projected to be 74% from 48%.

Excludes non-real estate-related depreciation and amortization of $505 and $305 for the three months ended September 30, 2017 and 2016, respectively, and $1,231 and $717 for the nine months ended September 30, 2017 and 2016, respectively. Funds from operations is calculated in accordance with the definition of FFO of the National Association of Real Estate Investment Trusts (NAREIT). See “Information About FFO, Core FFO and AFFO” below. Includes the Company's share from unconsolidated joint ventures of $673 and $362 for the three months ended September 30, 2017 and 2016, respectively, and $968 and $511 for the nine months ended September 30, 2017 and 2016, respectively. Includes the Company's share from unconsolidated joint ventures of $81 and $95 for the three months ended September 30, 2017 and 2016, respectively, and $256 and $285 for the nine months ended September 30, 2017 and 2016, respectively. Excludes expenditures for tenant spaces in properties that have not been owned by the Company for at least a year. In its Supplemental Operating and Financial Data furnished for the First Quarter 2016, the Company had presented the Adjusted FFO (AFFO) amount for the three months ended March 31, 2016 of $21,924, which did not properly reflect the effects of certain non-cash components of AFFO. The amount presented in this report of $57,944 for the nine months ended September 30, 2016 includes the corrected amount. Net Debt calculated by taking the sum of senior unsecured notes, unsecured revolving credit facility, and mortgages, loans payable and other obligations, and deducting cash and cash equivalents, all at period end. Equals Net Debt at period end divided by Adjusted EBITDA (for quarter periods, Adjusted EBIDTA annualized multiplying quarter amounts by 4). Calculated based on weighted average common shares outstanding, assuming redemption of Operating Partnership common units into common shares (10,439 and 10,498 shares for the three months ended September 30, 2017 and 2016, respectively, and 10,394 and 10,502 for the nine months ended September 30, 2017 and 2016, respectively), plus dilutive Common Stock Equivalents (i.e. stock options). $ in thousands, except per share amounts (unaudited) Funds from operations (“FFO”) is defined as net income (loss) before noncontrolling interests of unitholders, computed in accordance with generally accepted accounting principles (“GAAP”), excluding gains or losses from depreciable rental property transactions, and impairments related to depreciable rental property, plus real estate-related depreciation and amortization. The Company believes that FFO per share is helpful to investors as one of several measures of the performance of an equity REIT. The Company further believes that as FFO per share excludes the effect of depreciation, gains (or losses) from sales of properties and impairments related to depreciable rental property (all of which are based on historical costs which may be of limited relevance in evaluating current performance), FFO per share can facilitate comparison of operating performance between equity REITs. FFO per share should not be considered as an alternative to net income available to common shareholders per share as an indication of the Company’s performance or to cash flows as a measure of liquidity. FFO per share presented herein is not necessarily comparable to FFO per share presented by other real estate companies due to the fact that not all real estate companies use the same definition. However, the Company’s FFO per share is comparable to the FFO per share of real estate companies that use the current definition of the National Association of Real Estate Investment Trusts (“NAREIT”). A reconciliation of net income per share to FFO per share is included in the financial tables above. Core FFO is defined as FFO, as adjusted for items that may distort the comparative measurement of the Company’s performance over time. Adjusted FFO ("AFFO") is defined as Core FFO less (i) recurring tenant improvements, leasing commissions and capital expenditures, (ii) straight-line rents and amortization of acquired below-market leases, net, and (iii) other non-cash income, plus (iv) other non-cash charges. Core FFO and AFFO are both non-GAAP financial measures that are not intended to represent cash flow and are not indicative of cash flows provided by operating activities as determined in accordance with GAAP. Core FFO and AFFO are presented solely as supplemental disclosures that the Company’s management believes provides useful information regarding the Company's operating performance and its ability to fund its dividends. There are not generally accepted definitions established for Core FFO or AFFO. Therefore, the Company's measures of Core FFO and AFFO may not be comparable to the Core FFO and AFFO reported by other REITs. A reconciliation of net income to Core FFO and AFFO are included in the financial tables above. Information About FFO, Core FFO and AFFO

NAV is arrived at by calculating the estimated gross asset values for each of our 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. Unless otherwise noted, 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 Company's 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 value range is determined by adding or subtracting 0.50% to the mid-point terminal cap rate for office properties and 0.125% to the year 1 cap rate for multifamily properties. Property cash flows have been reduced by credit loss reserves and leasing and base building capital expenditures, including targeted Harborside renovations. 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. Includes Land $191 million (Plaza 4 - $90mm, One Lake St. $43 million, All other $58 million); Wegman's property ($62 million), seller financing notes ($65 million), 1031 funds ($39 million) and two out-of-service properties at cost ($36 million). 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. Joint venture investments are generally valued by: applying a capitalization rate to projected net operating income 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. Represents gross value per square factor unit prior to reduction of JV interests and debt.

15 Q3 2017 Notes: Net Asset Value (Unaudited) Company Highlights The valuation approach for assets in construction or lease-up are similar to that applied to assets undergoing repositioning/repurposing, as described below. After applying an estimated capitalization rate to a projected stabilized net operating income upon completion of the construction or lease-up activities, the Company deducts any estimated future costs 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 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. 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. Represents an estimate of management fee cost based on 3.0% of revenues, as the NOI presented is before cost for managing the portfolio. The multifamily valuation analysis totals to a Roseland NAV of $1,629,000,000, with the company’s share of this NAV of $1,473,000,000 (“MCRC Share”). This latter amount represents the company's share of Roseland NAV, net of the $156,000,000 attributable to Rockpoint's noncontrolling interest. 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.

Year-to-date, rents have rolled up 1.2% cash and 14.3% GAAP. For Core/Waterfront/Flex portfolio Q3 rents rolled down 0.6% cash and rolled up 14.6% GAAP. For the quarter, GAAP rents rolled up on 41 of the 42 transactions which qualified for inclusion in the statistic Average Rent: In Q3, 747,562 SF leased at: Leasing Costs: For Q3 transactions, we committed $2.03 per square foot per year of the lease term, and our year-to-date average is $2.16 2017 Expirations (Q4): Remaining 2017 expirations aggregate 681,000 square feet (net of 89,000 square feet in properties we plan to sell/repurpose): Represents 4.4% of leased square feet and 5.2% of annualized base rent; Average lease expirations on the Waterfront have in-place rental rates at approximately $33 per square-foot. Similar space in adjacent buildings have leased within the past year at average in-place rental rates of $45 per square-foot by Mack-Cali and our competitors. It is expected that the lease-up of this space is a "when, not if" scenario. Mack-Cali continues to add amenities to make these the buildings of choice in this market; 238,000 square feet in Urban and Suburban Core properties, represents a manageable 3.7% of Core portfolio. The product quality has drastically increased in this category as we removed the non-core buildings through sales.

Roseland Residential Portfolio Q3 2017

Management Discussion & Objectives 31 Q3 2017 Roseland manages a dynamic portfolio of owned, under construction, and future development assets on the New Jersey Waterfront, with the remaining holdings primarily in high-income, transit oriented suburban locations. We are a premier owner and developer of residential real estate on the New Jersey waterfront with direct access to Hudson Yards and Brookfield Place Roseland Residential Platform Poised For Continued Growth: Subsequent to quarter-end, the Company reached an agreement to acquire an approved residential development site in the Jersey City waterfront submarket adjacent to our existing holdings. We are projecting a mid-November closing and mid-2018 construction start for the 749-unit community, which will also include a school and a below market 20-year tax abatement RRT’s Q3 NAV was approximately $1.63B, comprised of $156M of Rockpoint equity and $1.47B of MC equity ($14.60/share) Rockpoint has an additional $150M capital commitment to Roseland RRT’s subordinate interest portfolio was reduced to 542 apartments (82% reduction compared to 3,025 units at year-end 2015) RRT continues to succeed in converting under performing office holdings to higher valued residential use (i.e. Signature Place in Morris Plains, NJ) RRT has a portfolio of strategic and valuable land holdings, mostly with zoning in place and a track record of on-time and on-budget product delivery Jersey City – 4,350 units Port Imperial – 2,026 units RRT’s lease-up communities have absorbed quickly in the market. Rents in our stabilized Jersey City holdings grew by 1.5% over the last year despite the simultaneous lease-up of several adjacent luxury buildings As detailed on page 33, we forecast continuing growth in RRT cash flow 2017 Lease-Up Highlights % Leased (Current) Stabilized NOI Stabilized Cash Flow Urby 95% $18.5M $9.85M Chase II 98% $4.9M $2.70M Quarry Place 76% $3.2M $1.11M Jersey City Urby at Harborside Quarry Place at Tuckahoe
