IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON JUNE 12, 2019.

This Proxy Statement, the Notice of Annual Meeting of Stockholders and Our Annual Report to Stockholders are available at http://investors.mack-cali.com/sec-filings.

At the Annual Meeting, the stockholders will consider and vote on the following matters:

YOUR VOTE IS VERY IMPORTANT. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE ELECTION OF EACH OF THE BOARD OF DIRECTORS' ELEVEN (11) DIRECTOR NOMINEES NAMED IN THIS PROXY STATEMENT. THE BOARD OF DIRECTORS ALSO UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE PROPOSAL TO ADOPT, ON AN ADVISORY BASIS, A RESOLUTION APPROVING THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AND "FOR" THE PROPOSAL TO RATIFY THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS FOR THE FISCAL YEAR ENDING DECEMBER 31, 2019. YOU CAN VOTE VIA THE INTERNET OR BY TELEPHONE OR BY MAIL BY COMPLETING, SIGNING AND DATING THE ENCLOSED WHITE PROXY CARD AND RETURNING IT IN THE POSTAGE-PAID ENVELOPE PROVIDED.

Bow Street Special Opportunities Fund XV, LP ("Bow Street") has notified the Company of its intent to nominate six (6) insurgent director candidates for election to the Board of Directors at the

Annual Meeting in opposition to the nominees recommended by our Board of Directors. As a result, you may receive solicitation materials, including a Gold proxy card, from Bow Street seeking your proxy to vote for the Bow Street nominees. THE BOARD OF DIRECTORS HAS NOT APPROVED OR NOMINATED, AND DOES NOT ENDORSE OR SUPPORT, ANY OF BOW STREET'S INSURGENT DIRECTOR NOMINEES. WE URGE YOU NOT TO SIGN OR RETURN ANY GOLD PROXY CARD SENT TO YOU BY BOW STREET, EVEN AS A PROTEST VOTE AGAINST BOW STREET AND ITS INSURGENT DIRECTOR CANDIDATES. Instead, our Board of Directors recommends that you vote FOR each of the Board of Directors' eleven (11) director nominees named in the Proxy Statement.

Solicitation. The Board of Directors is soliciting proxies for the Annual Meeting from our stockholders, and the Company will bear all attendant costs. These costs will include the expense of preparing and mailing proxy materials for the Annual Meeting and reimbursements paid to brokerage firms and others for their expenses incurred in forwarding solicitation material regarding the Annual Meeting to beneficial owners of the Company's common stock, par value $.01 per share (the "Common Stock"). The Company has retained MacKenzie Partners, Inc., 105 Madison Avenue, 14^th Floor, New York, New York 10016 ("MacKenzie Partners"), to perform various proxy solicitation services in connection with the solicitation of proxies for the Annual Meeting. The Company will pay MacKenzie Partners a fee not to exceed $[ · ], plus out-of-pocket expenses, for such services. MacKenzie Partners expects that approximately 30 of its employees will assist in the solicitation of proxies for the Annual Meeting. We may use several of our regular employees, who will not be specifically compensated, to solicit proxies from our stockholders, either personally or via the Internet or by telephone, facsimile or special delivery letter.

As a result of the proxy contest initiated by Bow Street, we may incur substantial additional costs in connection with the solicitation of proxies for the Annual Meeting. These additional solicitation costs are expected to include, among others, the fees and expenses of MacKenzie Partners, fees and expenses of our outside media and communications consulting firm, fees and expenses of outside counsel in connection with a contested election of the Company's directors, costs associated with SEC filings, increased printing and mailing costs related to additional mailings of solicitation materials to stockholders, and the costs of retaining an independent inspector of elections. Our aggregate expenses related to our solicitation of proxies for the Annual Meeting, excluding salaries and wages of our regular employees, any costs related to any litigation in connection with the Annual Meeting and expenses that we would ordinarily incur in connection with an uncontested annual meeting, are expected to be approximately $[ · ], of which approximately $[ · ] has been incurred as of the date of this Proxy Statement.

Under applicable regulations of the Securities and Exchange Commission (the "SEC"), members of the Board of Directors and certain officers and employees of the Company may be deemed to be "participants" with respect to the Company's solicitation of proxies in connection with the Annual Meeting by reason of their positions as directors and director nominees of the Company or because they may be soliciting proxies on our behalf. Certain information concerning such persons (the "Participants") is set forth in this Proxy Statement and Annex A hereto.

Householding of Proxy Materials. In accordance with a notice sent previously to beneficial owners holding shares in street name (for example, through a bank, broker or other holder of record) who share a single address with other similar holders, only one Annual Report and Proxy Statement is being

sent to that address unless contrary instructions were received from any stockholder at that address. This practice, known as "householding," is designed to reduce printing and postage costs. Any of such beneficial owners may discontinue householding by writing to the address or calling the telephone number provided for such purpose by their holder of record. Any such stockholder may also request prompt delivery of a copy of the Annual Report or Proxy Statement by contacting the Company at (732) 590-1010 or by writing to Gary T. Wagner, General Counsel and Secretary, Mack-Cali Realty Corporation, Harborside 3, 210 Hudson Street, Ste. 400, Jersey City, New Jersey 07311. Other beneficial owners holding shares in street name may be able to initiate householding if their holder of record has chosen to offer such service, by following the instructions provided by the record holder.

Voting. Stockholders of record may authorize the proxies named in the enclosed WHITE proxy card to vote their shares of Common Stock in the following manner:

Different Color Proxy Cards. Bow Street has notified the Company of its intent to nominate six (6) insurgent director candidates for election to the Board of Directors at the Annual Meeting in opposition to the nominees recommended by our Board of Directors. As a result, you may receive solicitation materials, including a Gold proxy card, from Bow Street seeking your proxy to vote for the Bow Street nominees. The Company is not responsible for the accuracy of any information provided by or relating to Bow Street contain in any proxy solicitation materials filed or disseminated by or on behalf of Bow Street or any other statements that Bow Street may otherwise make.

THE BOARD OF DIRECTORS HAS NOT APPROVED OR NOMINATED, AND DOES NOT ENDORSE OR SUPPORT, ANY OF BOW STREET'S INSURGENT DIRECTOR NOMINEES. WE URGE YOU NOT TO SIGN OR RETURN ANY GOLD PROXY CARD SENT TO YOU BY BOW STREET. Instead, our Board of Directors recommends that you vote "FOR" each of the Board of Directors' eleven (11) director nominees named in this Proxy Statement.

Voting to "withhold authority" with respect to any of Bow Street's nominees on its Gold proxy card is not the same as voting "FOR" the Board of Directors' eleven (11) director nominees. This is because a vote to "withhold authority" with respect to any of Bow Street's nominees on its Gold proxy card will revoke any previous proxy submitted by you to vote "FOR" the Board of Directors' eleven (11) director nominees on a WHITE proxy card, as only your latest dated and signed proxy card will be counted at the Annual Meeting. DO NOT RETURN ANY GOLD PROXY CARD SENT TO YOU BY BOW STREET, EVEN AS A PROTEST VOTE AGAINST BOW STREET AND ITS INSURGENT DIRECTOR NOMINEES.

The Company has provided you with the enclosed WHITE proxy card. The Board of Directors unanimously recommends using the enclosed WHITE proxy card to vote "FOR" each of the Board of Directors' eleven (11) director nominees named in this Proxy Statement. If the Company receives a validly executed WHITE proxy card from you, your shares will be voted by the Company proxies as indicated in your voting preference selection. We encourage you to cast your vote "FOR" each of the proposals, following the instructions on your WHITE proxy card, as promptly as possible.

If you have already voted using a Gold proxy card sent to you by Bow Street, you have every right and the ability to change your vote. We urge you to revoke that proxy by voting "FOR" the Board of Directors' eleven (11) director nominees named in this Proxy Statement by using the enclosed WHITE proxy card. Only the latest-dated and validly executed proxy that you submit will count at the Annual Meeting.

Revocability of Proxies. Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is exercised in the same manner in which it was given or by taking any of the following actions:

Written notices of revocation and other communications with respect to the revocation of proxies should be addressed to:

Mack-Cali Realty Corporation
Harborside 3, 210 Hudson Street, Ste. 400
Jersey City, New Jersey 07311
Attention: Gary T. Wagner, General Counsel and Secretary

If your shares are held in "street name," you may change your vote by submitting new voting instructions to your broker, bank or other nominee. You must contact your broker, bank or other nominee to find out how to do so.

If you have previously signed a Gold proxy card sent to you by Bow Street or otherwise voted according to instructions provided by Bow Street, you may change your vote and revoke your prior proxy by signing, dating and returning the enclosed WHITE proxy card in the accompanying envelope or by voting by telephone or via the Internet by following the instructions on the WHITE proxy card. DO NOT RETURN ANY GOLD PROXY CARD SENT TO YOU BY BOW STREET, EVEN AS A PROTEST VOTE AGAINST BOW STREET AND ITS INSURGENT DIRECTOR NOMINEES. Submitting a [ · ] proxy card sent to you by Bow Street (even if you withhold your vote on the Bow Street nominees) will revoke votes you have previously made via our WHITE proxy card.

Voting in Person. If you plan to attend the Annual Meeting and wish to vote in person, you will be given a ballot at the Annual Meeting. Stockholders who wish to attend the Annual Meeting will be required to present verification of ownership of our common stock, such as a bank or brokerage firm account statement, and will be required to present a valid government-issued picture identification, such as a driver's license or passport, to gain admittance to the Annual Meeting. No cameras, recording equipment, electronic devices, large bags, briefcases or packages will be permitted in the Annual Meeting.

Record Date; Outstanding Shares. The close of business on April 16, 2019 has been fixed as the record date (the "Record Date") for determining the holders of shares of Common Stock entitled to notice of, and to vote at, the Annual Meeting. Each share of Common Stock outstanding on the Record Date is entitled to one vote on all matters, and there are no cumulative voting rights. As of the Record Date, there were 90,336,336 shares of Common Stock issued and outstanding.

Voting Procedures; Quorum and Votes Required. Stockholder votes will be tabulated by the persons appointed by the Board of Directors to act as inspectors of election for the Annual Meeting. The inspectors of election will also determine whether a quorum is present. The presence at the Annual Meeting of a majority of the outstanding shares of Common Stock, represented either in person or by proxy, will constitute a quorum for the transaction of business at the Annual Meeting.

Shares represented by a properly executed and delivered proxy will be voted at the Annual Meeting and, when instructions have been given by the stockholder, will be voted in accordance with those instructions. If a properly executed and delivered WHITE proxy card does not provide instructions, then the shares represented by that proxy will be voted "FOR" the election of each of the Board of Directors' eleven (11) nominees for director named below, "FOR" the advisory approval of executive compensation, and "FOR" the ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm.

If your shares are held in the name of a bank, broker or other nominees, you will receive instructions from such nominee that you must follow in order to vote your shares. If your shares are not registered in your own name and you plan to vote your shares in person at the Annual Meeting, you should contact your broker or agent to obtain a broker's proxy card and bring it with you to the Annual Meeting in order to vote. Under New York Stock Exchange (the "NYSE") Rules, only the ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent auditors, as set forth in Proposal No. 3, is considered a "discretionary" item. This means that brokerage firms may vote in their discretion on Proposal No. 3 on behalf of beneficial owners who have not furnished a properly executed proxy card or delivered voting instructions to their broker at least ten days before the date of the Annual Meeting. In contrast, the election of directors as set forth in Proposal No. 1 and the advisory vote to approve executive compensation as set forth in Proposal No. 2 are considered non-discretionary items. This means that brokerage firms that have not received a properly executed proxy card or voting instructions from their clients may not vote on behalf of their clients with respect to Proposals Nos. 1 and 2. These so called "broker non-votes" will be included in the calculation of the number of shares considered to be present at the Annual Meeting for purposes of determining a quorum, but will not be included in the total of votes cast for the election of directors or the advisory vote for approval of executive compensation.

Proposal No. 1: Election of Directors. A plurality of the votes cast by the holders of shares of Common Stock present in person or by proxy at the Annual Meeting and entitled to vote in the election of directors is required for the election of directors. Accordingly, the eleven (11) director nominees that receive the greatest number of "FOR" votes will be elected to the Board of Directors. Abstentions, failures to vote and broker non-votes are not considered votes cast and, therefore, will have no effect on the outcome of the election of directors.

Proposal No. 2: Advisory Vote to Approve Executive Compensation. The affirmative vote of a majority of the votes cast by the holders of shares of our Common Stock present in person or by proxy at the Annual Meeting and entitled to vote on the proposal is required for the approval, on an advisory basis, of the compensation of the Company's named executive officers. Abstentions, failures to vote and broker non-votes are not considered votes cast and, therefore, will have no effect on this proposal.

Proposal No. 3: Ratification of the Appointment of Independent Auditors. The affirmative vote of a majority of the votes cast by the holders of shares of our Common Stock present in person or by proxy at the Annual Meeting and entitled to vote on the proposal is required for the ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent auditors. Abstentions and failures to vote are not considered votes cast and, therefore, will have no effect on this proposal. Because the ratification of the independent auditors is a discretionary item, we do not anticipate receiving any broker non-votes with respect to this proposal.

No Appraisal Rights. Under Maryland law, stockholders will not have appraisal or similar rights in connection with any proposal set forth in this Proxy Statement.

Statements made in this Proxy Statement may be forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements can be identified by the use of words such as "may," "will," "plan," "potential," "projected," "should," "expect," "anticipate," "estimate," "target," "continue," or comparable terminology. Such forward-looking statements are inherently subject to certain risks, trends and uncertainties, many of which the Company cannot predict with accuracy and some of which the Company might not even anticipate and involve factors that may cause actual results to differ materially from those projected or suggested. Readers are cautioned not to place undue reliance on these forward-looking statements and are advised to consider the factors listed above together with the additional factors under the heading "Disclosure Regarding Forward-Looking Statements" and "Risk Factors" in the Company's Annual Report on Form 10-K, as may be supplemented or amended by the Company's Quarterly Reports on Form 10-Q, which are incorporated herein by reference. The Company assumes no obligation to update or supplement forward-looking statements that become untrue because of subsequent events, new information or otherwise, except as required under applicable law.

The following is a chronology of the material events leading up to the filing of this Proxy Statement:

The Board of Directors regularly evaluates the Company's strategic direction and reviews alternatives for maximizing stockholder value, including potential strategic transactions.

On January 28, 2019, representatives of Bow Street and David Werner Real Estate Investments ("DWREI") contacted David J. Smetana, the Company's Chief Financial Officer, by telephone to request a meeting to discuss a potential transaction involving the Company.

On February 25, 2019, Michael J. DeMarco, the Company's Chief Executive Officer, Mr. Smetana, and Gary T. Wagner, the Company's General Counsel and Secretary, held an in-person meeting with representatives of Bow Street and DWREI. During the meeting, the Bow Street and DWREI representatives presented an unsolicited proposal (the "Proposal") to acquire the Company's suburban and waterfront office assets for $2.4 billion to $2.6 billion in cash, in a complex transaction in which the Company's Roseland Residential Trust subsidiary ("Roseland") and other residential assets of the Company would be spun-off to the Company's stockholders as a newly-formed, publicly-traded residential REIT (the "Proposed Transaction"). At the conclusion of the meeting, Mr. DeMarco informed the Bow Street and DWREI representatives that the Company's management would review the Proposal with the Company's financial and legal advisors, inform the Board of Directors of the receipt of the Proposal and review the Proposal at the upcoming Board of Directors meeting on March 13, 2019.

During the period from February 26, 2019 to March 8, 2019, the Company, in consultation with its financial and legal advisors, conducted a thorough review of the Proposal.

On February 26, 2018, as part of the Company's review process, Mr. Smetana held a telephonic conference with representatives of Bow Street and DWREI to review Bow Street's financial model and assumptions with respect to the newly-formed, publicly-traded residential REIT that would be created as part of the Proposed Transaction ("ResiCo"). Mr. Smetana also discussed with the representatives of Bow Street and DWREI the Company's commercial asset portfolio to clarify which of the Company's properties would be included in the suburban and waterfront office assets that Bow Street and DWREI were proposing to acquire, and which assets would remain in ResiCo following the completion of the Proposed Transaction. At the conclusion of the telephone conference, Mr. Smetana requested that Bow Street and DWREI provide back-up information for their financial model and assumptions relating to ResiCo.

On February 27, 2019, a representative of Bow Street sent an email to Mr. Smetana with certain financial information relating to the Proposal, including back-up information for Bow Street's financial model and assumptions with respect to ResiCo. On the same day, Mr. DeMarco also received a call from David Werner reiterating his interest in the Proposed Transaction.

On February 28, 2019, a representative of Bow Street sent an email to Mr. DeMarco suggesting that the parties hold another in-person meeting to discuss the Proposal on March 11, 2019 or another mutually convenient date.

On March 8, 2019, the Company informed Bow Street that the Board of Directors would review and consider the Proposal at its regularly scheduled quarterly meeting on March 13, 2019, as part of the Board of Directors' regular evaluation of the Company's strategic direction.

On March 10, 2019, Bow Street informed the Company of its intent to nominate a slate of candidates for election to the Board of Directors at the Annual Meeting prior to the March 15, 2019 deadline for submitting director nominations under the Company's bylaws, unless the Company agreed to extend such deadline to continue private discussions with Bow Street regarding the Proposal.

On March 13, 2019, the Board of Directors, at its regularly scheduled quarterly meeting, after careful evaluation of the Proposal, in consultation with its financial and legal advisors, unanimously

determined that the Proposal substantially undervalued the Company's core office portfolio, was based on unrealistic assumptions regarding ResiCo's trading multiples, was unworkable and, if consummated, would likely result in materially adverse tax consequences to the Company and its stockholders and would leave the Company and its stockholders without the wherewithal to capitalize on its residential assets and with shares of a small, undercapitalized company unlikely to achieve an attractive valuation in the public market. Accordingly, the Board of Directors determined that the Proposed Transaction was inadequate and not in the best interests of the Company's stockholders.

On March 14, 2019, the Company sent a letter to Bow Street and DWREI informing them of the Board of Directors' decision to reject the Proposal and explaining the reasons for the Board of Directors' decision.

Also on March 14, 2019, Bow Street delivered to the Company a formal notice of its intent to nominate a majority slate of six (6) candidates to stand for election to the Board of Directors at the Annual Meeting.

On March 18, 2019, the Company issued a press release and filed with the SEC a Current Report on Form 8-K disclosing the receipt of the notice of director nominations from Bow Street. In the press release, the Company announced that Bow Street delivered its notice of director nominations following the Board of Directors' unanimous decision to reject the Proposal, and explained the reasons for the Board of Directors' decision.

On March 21, 2019, Bow Street delivered to the Company a request to inspect the books and records of the Company under Section 1315(a) of the New York Business Corporation Law.

On March 27, 2019, William L. Mack, Chairman of the Board of Directors, and Mr. DeMarco held an in-person meeting with representatives of Bow Street and DWREI, at their request. At the meeting, the Bow Street and DWREI representatives asked the Company's representatives if the Company and its financial advisors had reconsidered their position with respect to the Proposal. The Company's representatives responded that the Board of Directors continued to believe that the Proposal was inadequate, for the reasons described in the press release issued by the Company on March 18, 2019. The Bow Street and DWREI representatives also indicated that Bow Street would be willing to withdraw its director nomination notice if the Company agreed to sell to Bow Street and DWREI certain of the Company's office properties at a "wholesale" price. The Company's representatives informed the Bow Street and DWREI representatives that the Company is not interested in selling any of these office properties at this time and, in any event, would not be willing to sell any of its assets or properties at a price that does not reflect their fair market value. The Company's representatives also stated, however, that the Company expected to continue to sell additional office assets in a tax efficient manner pursuant to the Company's strategic plan after completing the Flex portfolio sale and that Bow Street and DWREI were welcome to bid on such assets in a competitive manner.

On April 2, 2019, Mr. DeMarco held an in-person meeting with a representative of Bow Street, at the Bow Street representative's request. At the meeting, the Bow Street representative indicated that Bow Street would be willing to withdraw its director nomination notice if the Board of Directors agreed to (1) nominate three of Bow Street's insurgent director candidates (including at least one director candidate affiliated with Bow Street) for election to the Board of Directors at the Annual Meeting and (2) form a special committee of the Board of Directors to review and evaluate potential acquisition proposals involving the Company. Mr. DeMarco responded that in light of Bow Street's approximately 4.3% ownership of the Company's common stock, three directors would give Bow Street disproportionate representation on the Board of Directors. However, in order to avoid a costly and distracting proxy contest, the Board of Directors would consider nominating two independent candidates to be mutually identified by Bow Street and the Company (which candidates would not include any of Bow Street's nominees affiliated with Bow Street or DWREI) for election to the Board of Directors at the Annual Meeting. Mr. DeMarco also informed the Bow Street representative that

the Board of Directors does not believe that the formation of a special committee to review and evaluate potential acquisition proposals would be warranted at this time, because the Company is not currently conducting a sale process and any potential unsolicited acquisition proposals can be reviewed and evaluated by the full Board of Directors, as part of its regular evaluation of the Company's strategic direction.

On April 3, 2019, a representative of Bow Street sent an email to Mr. DeMarco with certain financial information relating to Bow Street's calculation of the net cash proceeds that would be available for distribution to the Company's stockholders under the Proposal as well as Bow Street's projections with respect to ResiCo's NAV following the completion of the Proposed Transaction. Upon review of these materials, the Company's management and financial advisors concluded that they did not include any new information that could lead the Company to reconsider its previous determination that the Proposal substantially undervalued the Company's core office portfolio, was based on unrealistic assumptions regarding ResiCo's trading multiples and failed to address the materially adverse tax consequences to the Company and its stockholders that would likely result from the Proposed Transaction.

On April 9, 2019, Mr. DeMarco held a telephone conversation with a representative of Bow Street, during which they discussed matters relating to the Proposal and Bow Street's director nominations. During the telephone conversation, the Bow Street representative indicated that Bow Street and DWREI disagreed with the Company's determination that the amount of net cash proceeds from the Proposed Transaction that would be available for distribution to Mack-Cali stockholders would likely be materially lower than $8.00 to $10.00 per share, as suggested in the Proposal. However, the Bow Street representative did not explain how Bow Street and DWREI proposed to finance the Proposed Transactions, including the additional amount of cash that would be required to address the materially adverse tax consequences, frictional costs and structuring constraints that would likely be associated with the Proposed Transaction. The Bow Street representative also acknowledged that the Proposed Transaction and the cash purchase price of $2.4 billion to $2.6 billion for the Company's suburban and waterfront office assets, as suggested in the Proposal, were subject to due diligence.

Mr. DeMarco responded that the Board of Directors continues to believe that the Proposed Transaction is inadequate and not in the best interests of the Company's stockholders. However, in order to avoid a costly and distracting proxy contest, the Board of Directors would consider nominating one independent candidate from Bow Street's slate of nominees for election to the Board of Directors at the Annual Meeting and subsequently nominating an additional independent candidate to be mutually identified by Bow Street and the Company for election to the Board of Directors at the Company's 2020 annual meeting of stockholders. Mr. DeMarco emphasized that these director candidates must be independent and would not include any of Bow Street's nominees affiliated with Bow Street or DWREI. Mr. DeMarco also reiterated that the Board of Directors continues to believe that the formation of a special committee to review and evaluate potential acquisition proposals involving the Company, as suggested by the Bow Street representative during the April 2, 2019 in-person meeting, would not be warranted at this time, because the Company is not currently conducting a sale process and any potential unsolicited acquisition proposals can be reviewed and evaluated by the full Board of Directors, as part of its regular evaluation of the Company's strategic direction. Mr. DeMarco also stated that, as discussed by the parties during the March 27, 2019 in-person meeting, while the Company was not willing to sell any of its assets or properties to Bow Street or DWREI at a price that does not reflect their fair market value, the Company expected to continue to sell additional office assets in the fourth quarter of 2019, in a tax efficient manner pursuant to the Company's strategic plan, and would be willing to discuss such sales with Bow Street and DWREI at such time, if they are interested in purchasing such assets at a fair price. Mr. DeMarco also informed the Bow Street representative that the Company needed to receive a response to its offer from Bow Street by Thursday, April 11, 2019, as the Company intended to file its preliminary proxy statement with the SEC no later than Friday, April 12, 2019.

On April 12, 2019, a representative of Bow Street sent an email to Mr. DeMarco stating that, as previously indicated by the Bow Street representative during the April 9, 2019 telephone conversation with Mr. DeMarco, the $8.00 to $10.00 per share was the amount of cash proceeds from the Proposed Transaction that Bow Street and DWREI intended to deliver to Mack-Cali stockholders, net of frictional costs. However, the email did not specify whether Bow Street and DWREI were proposing to increase the $2.4 billion to $2.6 billion cash price for the Company's suburban and waterfront office assets, as indicated in the Proposal, or otherwise explain how they proposed to finance the Proposed Transaction, including the additional amount of cash that would be required to address the materially adverse tax consequences, frictional costs and structuring constraints that would likely be associated with the Proposed Transaction. The email also stated that, in response to the Company's offer to nominate two of Bow Street's independent director candidates for election to the Board of Directors, Bow Street proposed that the Company add two of Bow Street's director nominees to the Board of Directors in 2019 and an additional Bow Street nominee in 2020, for a total of three directors. While the email stated that Bow Street was generally open to the Company's input on its director candidates, it did not indicate Bow Street's willingness to accept the Company's requirement that its director candidates must be independent and not affiliated with Bow Street or DWREI. In addition, the email stated that Bow Street requested that the Board of Directors announce the exploration of strategic alternatives to maximize stockholder value, and indicated that Bow Street and DWREI expected their Proposal to be a part of that process, despite the previous indications by the Company's representatives that the Company is not currently engaged in a process to sell or break up itself.

Also on April 12, 2019, the Company filed its preliminary proxy statement with the SEC.

On April 15, 2019, Mr. DeMarco sent a letter to Bow Street on behalf of the Board of Directors. Mr. DeMarco's letter stated that the Board of Directors continued to have serious concerns regarding the Proposal, which had been previously rejected by the Board, and described the Board's rationale for determining that the Proposal was unworkable, grossly inadequate from a value perspective and not in the best interests of Mack-Cali stockholders, including the Board's belief that: (i) the Proposed Transaction grossly undervalues Mack-Cali's office assets; (ii) Bow Street has not provided any evidence of its ability to finance the Proposed Transaction; (iii) Bow Street has not demonstrated that it understands the significant leakage that would likely result from the material tax, frictional and other costs associated with the Proposed Transaction, nor has it stated how it would cover such leakage; (iv) the Proposal is based on unrealistic assumptions regarding the post-transaction trading levels of the new residential REIT; (v) the Proposed Transaction would leave Mack-Cali stockholders with shares of a small, highly leveraged public company unlikely to achieve an attractive market valuation; (vi) the new residential REIT would likely have insufficient cash flows to carry its substantial debt burden, fund its multifamily development activities or pay meaningful dividends to its stockholders; and (vii) tax concerns make a partial sale of a substantial portion of the Company's assets, such as the one contemplated in the Proposed Transaction, economically inadvisable for the Company and its stockholders. The letter also described the Board's efforts to work constructively with Bow Street in order to avoid a costly and distracting proxy contest, including the Board's willingness to nominate two independent candidates to be mutually selected by Bow Street and the Company from Bow Street's slate of four director nominees for election to the Board of Directors at the Annual Meeting.

On April 16, 2019, Bow Street sent a letter to the Board of Directors, in which it reiterated and described the Proposal, summarized the economic terms of the Proposed Transaction, purported to explain Bow Street's rationale for the Proposed Transaction and its reasons for nominating a slate of director candidates for election to the Board of Directors at the Annual Meeting, and urged the Board to engage with Bow Street regarding the Proposal as well as to immediately form a special committee of independent directors to explore strategic alternatives to maximize stockholder value. On the same day, Bow Street issued a press release announcing its letter to the Board of Directors and filed its preliminary proxy statement with the SEC.

Also on April 16, 2019, the Company issued a press release announcing the letter sent by Mr. DeMarco to Bow Street on April 15, 2019.

Bow Street has notified the Company of its intent to nominate six (6) persons for election to the Board of Directors at the Annual Meeting in opposition to the nominees recommended by our Board of Directors, making this a contested election. In a contested election, the Company's bylaws provide that the election will be determined on a plurality voting standard, with the eleven (11) nominees that receive the greatest number of "FOR" votes elected to the Board of Directors. Abstentions, failures to vote and broker non-votes are not considered votes cast and will have no effect on the outcome of the director elections. Voting "withhold" with respect to a Bow Street nominee on its proxy card is NOT the same as voting "FOR" the Board of Directors' nominees on the WHITE proxy card because voting "withhold" on a Bow Street nominee on its Gold proxy card will revoke any previous proxy submitted by you, including any vote you may have made for the Board of Directors' nominees. The only way to support the Board of Directors' nominees is to vote "FOR" the Board of Directors' nominees on the WHITE proxy card and to disregard, and not return, any Gold proxy card that you receive from Bow Street. See "Policies Relating to the Election of Directors."

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF ALL NOMINEES NAMED ABOVE BY SIGNING, DATING AND RETURNING THE WHITE PROXY CARD. THE BOARD OF DIRECTORS DOES NOT ENDORSE ANY BOW STREET NOMINEES AND URGES YOU NOT TO VOTE USING THE [ · ] PROXY CARD SENT TO YOU BY BOW STREET, EVEN AS A PROTEST VOTE AGAINST BOW STREET AND ITS INSURGENT DIRECTOR NOMINEES.

Mack Agreement. In connection with the Company's combination with The Mack Company in December 1997, William L. Mack, Mitchell E. Hersh and Earle I. Mack were appointed to the Company's Board of Directors. Pursuant to an agreement (the "Mack Agreement") entered into between the Company and members of the Mack Group (as defined below) in connection with the Company's combination with The Mack Company, if any of Messrs.

Mack, a former director of the Company, and Frederic Mack, a member of the Advisory Board of the Company. Effective January 15, 2004, Earle I. Mack resigned from the Board of Directors.

Mack's seat on the Board of Directors for the remainder of its term and was re-elected to the Board of Directors both at the 2005 Annual Meeting, the 2008 Annual Meeting, the 2011 Annual Meeting and the 2014 Annual Meeting. In addition, for as long as members of the Mack Group maintain at least the "Mack Significant Interest" (as defined below), the Mack Group has the right to re-nominate, and the Company will support, Messrs. W. Mack and D. Mack (or their

Tax Protection Agreements. Through February 2016, the Company could not dispose of or distribute certain of its properties which were originally contributed by certain unrelated common unitholders of the Operating Partnership, without the express written consent of such common unitholders except in a manner which would not result in recognition of any built-in-gain (which may result in an income tax liability) or which reimbursed the appropriate specific common unitholders for the tax consequences of the recognition of such built-in-gains (collectively, the "Property Lock-Ups"). The aforementioned restrictions did not apply in the event that the Company sold all of its properties or in connection with a sale transaction which the Company's Board of Directors determined was reasonably necessary to satisfy a material monetary default on any unsecured debt, judgment or liability of the Company or to cure any material monetary default on any mortgage secured by a property. The Property Lock-Ups expired in February 2016.

Upon the expiration of the Property Lock-Ups, the Company is generally required to use commercially reasonable efforts to prevent any sale, transfer or other disposition of the subject properties from resulting in the recognition of built-in gain to the specific common unitholders, which include members of the Mack Group (which includes William L. Mack, Chairman of the Company's Board of Directors; David S. Mack, director; and Earle I. Mack, a former director), the Robert Martin Group (which includes Robert F. Weinberg, a former director and current member of the Company's Advisory Board), and the Cali Group (which includes John R.

As of December 31, 2018, 79 of the Company's properties, with an aggregate net book value of approximately $1.4 billion, have lapsed restrictions and are subject to these conditions.

Acquisitions and Other Transactions. Certain directors and executive officers of the Company (or members of their immediate families or related trusts) and persons who hold more than 5% of the outstanding shares of Common Stock (or Units in the Operating Partnership) had direct or indirect interests in certain transactions involving the Company, the Operating Partnership or their affiliates in the last fiscal year, as follows:

Policies and Procedures. The Company has a written policy with respect to the review, approval and ratification of related person transactions. This policy applies to any transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness), or any series of similar transactions, arrangements or relationships, in which (i) the Company is a participant and (ii) any "related person" (defined as an employee, director, director nominee, an executive officer or someone who owns more than 5% of our common shares, or an immediate family member of any of the foregoing persons, with certain exceptions) has or will have a direct or indirect interest. Under the policy, the Company's General Counsel will determine whether a transaction meets the definition of a related person transaction that will require review by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee will review all related person transactions referred to them and, based on the relevant facts and circumstances, will decide whether or not to approve such transactions. Only those transactions that are in, or are not inconsistent with, the best interests of the Company and its stockholders will be approved. If the Company becomes aware of an existing related person transaction that was not approved under this policy, the matter will be referred to the Nominating and Corporate Governance Committee and it will evaluate all options available, including ratification, amendment or termination of the transaction.

The Company has determined that, under the policy, the following types of transactions will be deemed to be pre-approved: (i) employment of an executive officer if the related compensation is required to be reported in the Company's proxy statement; (ii) employment of an executive officer if he or she is not an immediate family member of another executive officer or director of the Company, the related compensation would have been reported in the Company's proxy statement if he or she was a "named executive officer" and the Company's Executive Compensation and Option Committee approved (or recommended that the Board approve) such compensation; (iii) compensation paid to a director if the compensation is required to be reported in the Company's proxy statement; (iv) any transaction where the related person's interest arises solely from the ownership of the Company's Common Stock and all holders of the Company's Common Stock received the same benefit on a pro rata basis; (v) any transaction in which the rates or charges incurred are subject to governmental regulation; and (vi) any transaction involving bank depositary of funds, transfer agent, registrar, trustee under a trust indenture or similar services.

Under the policy, the General Counsel's determination of whether a transaction meets the definition of a related person transaction is based upon his assessment of the transaction under Item 404 of Regulation S-K without regard to the amounts involved. The Company's policy provides that any related person transaction referred to the Nominating and Corporate Governance Committee for consideration is evaluated based on all of the relevant facts and circumstances available, including (if applicable) but not limited to: (i) the benefits to the Company; (ii) the impact on a director's independence in the event the related person is a director, an immediate family member of a director or an entity in which a director is a partner, shareholder or executive officer; (iii) the availability of other sources for comparable products or services; (iv) the terms of the transaction; and (v) the terms available to unrelated third parties or to employees generally.

The policy prohibits a director from participating in any review, consideration or approval of any related person transaction with respect to which the director or any of his or her immediate family

members is the related person. The policy also provides that the only transactions that may be approved are those transactions that are in, or are not inconsistent with, the best interests of the Company and its stockholders.

The Board of Directors has adopted the NYSE's standards for determining the independence of its members and believes that it interprets these requirements conservatively. In applying these standards, the Board of Directors considers commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships, among others, in assessing the independence of directors, and must disclose any basis for determining that a relationship is not material. The Board of Directors has determined that seven of ten of its current members, namely Alan S. Bernikow, Nathan Gantcher, Kenneth M. Duberstein, Alan G. Philibosian, Irvin D. Reid, Rebecca Robertson and Vincent Tese, are independent directors within the meaning of such NYSE independence standards in terms of independence from management. Additionally, the Board of Directors has determined that, if elected to the Board of Directors at the Annual Meeting, both Lisa Myers and Laura Pomerantz will be independent directors, such that if all of the Board of Directors' director nominees are elected at the Annual Meeting, eight of the eleven directors will be independent. In making this determination, the Board of Directors did not exclude from consideration as immaterial any relationship potentially compromising the independence of any of the above directors.

Section 16(a) of the Exchange Act, requires the Company's executive officers, directors and persons who beneficially own more than 10% of the Company's Common Stock to file initial reports of ownership and reports of changes of ownership (Forms 3, 4 and 5) of the Common Stock with the SEC and the NYSE. Executive officers, directors and greater than 10% holders are required by SEC regulations to furnish the Company with copies of such forms that they file.

To the Company's knowledge, based solely on the Company's review of the copies of such reports received by the Company, the Company believes that for the fiscal year 2018, its executive officers, directors and greater than 10% beneficial owners complied with all Section 16(a) filing requirements applicable to such persons.

The Company is dedicated to responsible environmental, social and community stewardship as an essential part of our mission to build a successful business and to shape the communities we serve throughout our portfolio, in addition to our workplace community. Below are some highlights of our commitment to ESG principles.

The Board of Directors believes that continued growth of stockholder value in a socially responsible manner is consistent with the Company's overall strategy to continue to enhance the Company's reputation as a property manager of choice and promotes an environmental strategy that supports "green" building initiatives. The Environmental Protection Agency (the "EPA") encourages companies to reduce greenhouse gas emissions and conserve energy through what is now a voluntary program, Energy Star. In 1999, the EPA introduced its national energy performance rating systems for buildings. The program provides assessment tools to help building managers achieve greater energy efficiency and realize associated cost savings. The Company has been an Energy Star partner since the inception of the program in 1999. As such, the Company is required to, among other things, further track and benchmark its energy performance and broaden its plan to reduce energy intensity across its

properties by following the energy management strategy available through Energy Star. In addition, we have undertaken a number of green initiatives that not only conserve energy and reduce waste, but offer our tenants cost-effective incentives to promote sustainability efforts throughout our portfolio, including the following:

Whether through time, effort or monetary donations, we are committed to nourishing the betterment of the communities we serve, and our employees play active roles in numerous charitable organizations. As a company, we have regularly supported Rising Tide Capital, Angels of Hope and Susan G. Komen in an effort to better serve the community we call home.

We are also seek to foster a workplace where our employees are treated fairly and are highly motivated to succeed by promoting wellness initiatives, educational programs and leadership training and providing anti-bullying and anti-harrasment policies and training. We embrace diversity and are committed to providing equal employment opportunities for training, compensation, transfer, promotion and other aspects of employment for all qualified applicants and employees without regard to sex, race, color, religion, ethnicity, national origin, age, disability, sexual orientation, gender identity or gender expression.

In March 2018, the Board of Directors was expanded from nine to ten members by adding Michael J. DeMarco. The Board of Directors was further expanded from ten to eleven members in February 2019, and the Company has nominated Lisa Myers and Laura Pomerantz for election to the Board of Directors at the Annual Meeting. In order to comply with certain technical requirements of Maryland law, the Board of Directors also intends to appoint Ms. Myers to the Board of Directors prior to the Annual Meeting to fill the vacancy resulting from the increase in the size of the Board of Directors from ten to eleven members.

We are dedicated to maintaining a high standard for corporate governance predicated on integrity, ethics, diversity and transparency. As part of these efforts, we have begun the process to create an environmental, societal and governance management committee consisting of executive officers and employees to help lead the effort in identifying and implementing policies that will improve our environmental, social and community stewardship and workplace environment.

Our Board of Directors remains committed to the highest standard for corporate governance. All of our board members stand for re-election every year. Of our current seven independent directors, one is African American and one is female and we have nominated an additional two female candidates for election to our Board of Directors at the Annual Meeting. Additionally, in response to stockholder feedback solicited as part of our stockholder outreach efforts, we recently amended our bylaws to improve our corporate governance policies and procedures. Our new amended and restated bylaws now generally allow stockholders to propose amendments to the bylaws for approval by the stockholders. Additionally, each director nominee that is not elected by a majority of the votes cast in an uncontested election of directors is now required to tender their resignation for consideration by the Nominating and Corporate Governance Committee.

During 2018, the entire Board of Directors met six (6) times and acted by unanimous written consent four (4) times. In 2018, no director attended fewer than 75% of the total number of meetings of the Board of Directors and all committees of the Board of Directors on which he or she served. The Company does not have a formal policy regarding attendance by members of the Board of Directors at the annual meetings of stockholders, but the Company strongly encourages all members of the Board of Directors to attend its annual meetings and expects such attendance except in the event of exigent circumstances. All of the members of the Board of Directors at the time of the 2018 annual meeting of stockholders (the "2018 Annual Meeting") were in attendance at the 2018 Annual Meeting.

Currently, the Company has separated the roles of Chief Executive Officer and Chairman of the Board. The Company believes that at this time the separation of these roles permits the Chairman of the Board to focus on oversight of the Company's long-term corporate development goals while the Chief Executive Officer focuses on the strategic direction of the Company and oversees the day to day performance of the other executive officers in executing the Company's business plan. In addition, in March 2014, the Board of Directors appointed Alan S. Bernikow as its Lead Independent Director. The Lead Independent Director acts as a liaison between the Chairman of the Board and the independent directors and advises the Chairman of the Board with respect to the quality, quantity and timeliness of the flow of information from management as necessary for the independent directors to perform their duties effectively and responsibly, including requesting that certain material be included in materials prepared for the Board of Directors, approving agendas for meetings of the Board of Directors, and ensuring that there is sufficient time for discussion of all agenda items at meetings of the Board of Directors. Stockholders may contact the Lead Independent Director as further described below under the heading "Stockholder Communications," and if requested by significant stockholders, the Lead Independent Director shall be available for consultation. The Board of Directors believes that its Lead Independent Director structure, including the duties and responsibilities described above, provides the same independent leadership, oversight, and benefits for the company and the Board of Directors that would be provided by an independent Chairman of the Board.

The Lead Independent Director also shall preside at all meeting of the Board of Directors at which the Chairman of the Board is not present and all Executive Sessions of the Board of Directors consisting only of non-management directors. Such Executive Sessions will be held at least once per year, periodically as determined by the non-management directors, and will typically occur immediately following the regularly scheduled quarterly meetings of the Board of Directors, or at any other time and place as the Lead Independent Director or non-management directors may determine. Interested parties may submit matters for consideration to the non-management directors by utilizing the procedures identified under "Stockholder Communications" in this Proxy Statement. During 2018, the non-management directors met in Executive Session four (4) times.

Pursuant to authority vested in the Audit Committee of the Board of Directors pursuant to its charter, the Audit Committee is responsible for overseeing the Company's financial risk exposure and the Company's risk assessment and risk management policies and procedures. The Audit Committee discharges its risk oversight responsibilities as part of its quarterly reviews of the Company's quarterly and annual financial statements by discussing with management, the Company's independent auditors and outside legal counsel the Company's risk profile, its financial risk exposure and its risk mitigation policies and procedures. In addition, the Executive Compensation and Option Committee, in consultation with the independent compensation consultant to the Executive Compensation and Option Committee, conducted an annual risk assessment of the Company's compensation programs as described under "Compensation Risk Assessment" in this Proxy Statement. The Company does not believe that the performance of these oversight functions by these committees has any effect on the leadership structure of the Board of Directors.

The Board of Directors has adopted equity ownership guidelines that require each non-employee director to own an aggregate amount of Common Stock of the Company, units of limited partnership interest of Mack-Cali Realty, L.P. redeemable for shares of Common Stock of the Company or units under the Company's Deferred Compensation Plan for Directors equal in value to five (5) times the annual cash retainer paid to directors, currently $325,000. Such ownership level must be achieved by the later to occur of (i) March 8, 2019 or (ii) the three-year anniversary of the date the director is elected to the Board of Directors. All directors of the Company are in compliance with the equity ownership guidelines for directors, including Ms. Robertson who qualifies on the basis of being within the three-year transition period from her initial appointment to the Board of Directors in September 2016.

In March 2012, the Board of Directors, on the recommendation of its Nominating and Corporate Governance Committee, adopted a retirement policy for directors. Pursuant to this policy, the Board of Directors has amended the Company's Corporate Governance Principles to provide that a director may neither stand nor be nominated for re-election to the Board of Directors after attaining the age of 80. The Board of Directors proactively considers the overall size and composition of the Board of Directors and reviews and monitors management development and succession planning activities. The Chief Executive Officer regularly presents management's perspective on business objectives and discusses their perspective on the Company's deep pool of talented employees and succession planning for the Company.

The Board of Directors also has adopted a policy that provides that executive officers, employees, and directors may not acquire securities issued by the Company or any of its affiliates using borrowed funds, may not use margin in respect of securities issued by the Company or any of its affiliates, may not pledge securities issued by the Company or any of its affiliates as collateral, and may not engage in hedging or other transactions with respect to their ownership of securities issued by the Company or its affiliates, each of which the Board of Directors believes would be inconsistent with the purposes and intent of the stock ownership guidelines applicable to directors and the Chief Executive Officer.

In accordance with Rule 10A-3 of the Exchange Act, the Audit Committee provides for employees to contact the audit committee in writing or by telephone, on a confidential, anonymous basis, to submit concerns regarding questionable accounting or auditing matters, and the Audit Committee has policies and procedures, subject to the Company's internal controls, for the retention, and treatment of complaints.

The Board of Directors has three committees: the Audit Committee, the Executive Compensation and Option Committee, and the Nominating and Corporate Governance Committee.

Audit Committee. The Company has an Audit Committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. The Audit Committee consists of Alan S. Bernikow, chairman, Nathan Gantcher, Irvin D. Reid and Rebecca Robertson. The Audit Committee authorizes and approves the engagement of the Company's independent registered public accountants, reviews with the Company's independent registered public accountants the scope and results of the audit engagement, approves or establishes pre-approval policies for all professional audit and permissible non-audit services provided by the Company's independent registered public accountants, considers the range of audit and non-audit fees, and reviews the adequacy of the Company's internal control over financial reporting, disclosure controls and procedures and internal audit function. The Audit Committee also assists the Board of Directors in overseeing (1) the integrity of the Company's financial statements, (2) the Company's compliance with legal and regulatory requirements, (3) the quarterly evaluation of the performance of the internal audit functions performed by the Company's internal auditors, (4) the Company's independent registered public accounting firm's qualifications and independence, and (5) the performance of the Company's independent registered public accountants. See "Report of the Audit Committee of the Board of Directors" below. The Board of Directors has determined that each of the members of the Audit Committee is an "independent" director within the meaning of the NYSE Independence Standards and Rule 10A-3 promulgated by the SEC under the Exchange Act. The Board of Directors also has determined that each of Alan S. Bernikow, Nathan Gantcher, Irvin D. Reid and Rebecca Robertson satisfies applicable financial literacy standards of the NYSE, and that Alan S. Bernikow qualifies as an Audit Committee Financial Expert under applicable SEC Rules. In addition to serving on the Audit Committee, Mr. Bernikow currently serves as a member of the audit committee of three other public companies. The Board of Directors has determined that Mr. Bernikow's simultaneous service on the audit committees of these other public companies will not impair his ability to effectively serve on the Company's Audit Committee and fulfill his duties as its chairman. The Audit Committee met four (4) times during 2018.

Executive Compensation and Option Committee. The Executive Compensation and Option Committee consists of Nathan Gantcher, chairman, Kenneth M. Duberstein, Alan G. Philibosian and Vincent Tese. The Executive Compensation and Option Committee is responsible for implementing the Company's compensation philosophies and objectives, establishing remuneration levels for executive officers of the Company and implementing the Company's incentive programs, including the Company's stock option and incentive plans. The Board of Directors has determined that each of the members of the Executive Compensation and Option Committee is an "independent" director within the meaning of the NYSE Independence Standards, Rule 10C-1 promulgated by the SEC under the Exchange Act, and meets the "outside director" requirements of Section 162(m) of the Internal Revenue Code, as amended (the "Code"), and is a "non-employee" director under Rule 16b-3 under Section 16 of the Exchange Act. The Executive Compensation and Option Committee met seven (7) times in 2018.

Pursuant to its charter, the primary purposes of the Executive Compensation and Option Committee are (i) to assist the Board of Directors in discharging its responsibilities in respect of compensation of the Company's executive officers; and (ii) to review and administer the Company's compensation and benefit programs. In addition, pursuant to its charter, the Executive Compensation and Option Committee is responsible for establishing and reviewing annual and long term corporate goals and objectives relevant to compensation of the Company's executive officers in light of performance goals and objectives. The Executive Compensation and Option Committee has sole authority to determine and approve the compensation levels of the executive officers. Except for the delegation of authority to the Chief Executive Officer to grant certain de minimis equity compensation awards to non-executive employees of the Company, the Executive Compensation and Option Committee has not delegated, and does not delegate, any of its responsibilities to any other person. The manner in which the committee discharges its responsibilities is described under the heading "Compensation Discussion & Analysis" below.

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee consists of Vincent Tese, chairman, Kenneth M. Duberstein, Alan G. Philibosian and Irvin D. Reid. The Board of Directors has determined that each of the members of the Nominating and Corporate Governance Committee is an "independent" director within the meaning of the NYSE Independence Standards. The Nominating and Corporate Governance Committee met three (3)times in 2018.

The Nominating and Corporate Governance Committee identifies individuals qualified to become members of the Board of Directors and recommends to the Board of Directors the slate of directors to be nominated at the Annual Meeting. The Nominating and Corporate Governance Committee will consider recommendations for nominees for directorships submitted by stockholders, provided that the Nominating and Corporate Governance Committee will not entertain stockholder nominations from stockholders who do not meet the eligibility criteria for submission of stockholder proposals under SEC Rule 14a-8 of Regulation 14A under the Exchange Act. Stockholders may submit written recommendations for Nominating and Corporate Governance Committee appointments or recommendations for nominees to the Board of Directors, together with appropriate biographical information and qualifications of such nominees, to the Company's General Counsel following the same procedures as described in "Stockholder Communications" in this Proxy Statement. In order for the Nominating and Corporate Governance Committee to consider a nominee for directorship submitted by a stockholder, such recommendation must be received by the General Counsel by the time period set forth in the Company's most recent proxy statement for the submission of stockholder proposals under SEC Rule 14a-8 of Regulation 14A under the Exchange Act. The General Counsel shall then deliver any such communications to the Chairman of the Nominating and Corporate Governance Committee.

The Nominating and Corporate Governance Committee analyzes, on an annual basis, Board member skills and attributes, and recommends to the Board of Directors appropriate individuals for nomination as Board members. Based on the Company's strategic plan, the Nominating and Corporate Governance Committee developed a skills matrix to assist it in considering the appropriate balance of experience, skills and attributes required of a director and to be represented on the Board as a whole. The skills matrix is periodically reviewed and updated by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee evaluates potential Board candidates against the skills matrix.

The skills matrix has two sections—a list of core criteria that every member of the Board should meet and a list of skills and attributes desired to be represented collectively on the Board. The skills matrix reflects the following core director criteria that should be satisfied by each director or nominee:

The skills matrix reflects the following skills and attributes desired to be represented collectively on the Board as a whole:

Our Nominating and Corporate Governance Committee strives to maintain a balance of tenure on the Board of Directors. Long-serving directors bring valuable experience with our company and familiarity with the challenges it has faced over the years, while newer directors bring fresh perspective and new ideas.

Although the Nominating and Corporate Governance Committee does not have a formal diversity policy, it endeavors to comprise the Board of Directors and its committees of members with a broad mix of professional and personal backgrounds. Thus, the Nominating and Corporate Governance Committee accords some weight to the individual professional background and experience of each director. Further, in considering nominations, the Nominating and Corporate Governance Committee takes into account how a candidate's professional background would fit into the mix of experiences represented by the then-current Board of Directors. When evaluating a nominee's overall qualifications, the Nominating and Corporate Governance Committee does not assign specific weights to particular criteria, and no particular criterion is necessarily required of all prospective nominees. In addition to the aforementioned criteria, when evaluating a director for re-nomination to the Board of Directors, the Nominating and Corporate Governance Committee will also consider the director's history of attendance at board and committee meetings, the director's preparation for and participation in such meetings, and the director's tenure as a member of the Board of Directors.

The Board of Directors has adopted written charters for the Audit Committee, the Executive Compensation and Option Committee, and the Nominating and Corporate Governance Committee. The Company makes available free of charge on or through its internet website items related to corporate governance matters, including, among other things, the Company's corporate governance principles, charters of the various committees of the Board of Directors, and the Company's code of business conduct and ethics applicable to all employees, officers and directors. The Company's internet website is www.mack-cali.com. The Company intends to disclose on its internet website any amendments to or waivers from its code of business conduct and ethics as well as any amendments to its corporate governance principles or the charters of the various committees of the Board of Directors. Any stockholder also may obtain copies of these documents, free of charge, by sending a request in writing to: Mack-Cali Realty Corporation, Investor Relations Department, Harborside 3, 210 Hudson Street, Ste. 400, Jersey City, New Jersey 07311.

All stockholder communications must (i) be addressed to the General Counsel of the Company, Mack-Cali Realty Corporation, Harborside 3, 210 Hudson Street, Ste. 400, Jersey City, New Jersey 07311 or at the General Counsel's internet e-mail address at generalcounsel@mack-cali.com; (ii) be in writing either in print or electronic format; (iii) be signed by the stockholder sending the

communication; (iv) indicate whether the communication is intended for a specific director(s), the entire Board of Directors, the Nominating and Corporate Governance Committee, the Lead Independent Director, or all non-management directors; (v) if the communication relates to a stockholder proposal or director nominee, identify the number of shares held by the stockholder, the length of time such shares have been held, and the stockholder's intention to hold or dispose of such shares, provided that the Board of Directors and the Nominating and Corporate Governance Committee will not entertain stockholder proposals or stockholder nominations from stockholders who do not meet the eligibility and procedural criteria for submission of shareholder proposals under either SEC Rule 14a-8 of Regulation 14A under the Exchange Act or the advanced notice provisions of our bylaws; and (vi) if the communication relates to a director nominee being recommended by the stockholder, must include appropriate biographical information of the candidate. See "Submission of Stockholder Proposals."

Upon receipt of a stockholder communication that is compliant with the requirements identified above, the General Counsel shall promptly deliver such communication to the appropriate board or committee member(s) identified by the stockholder as the intended recipient of such communication by forwarding the communication to either the Chairman of the Board of Directors with a copy to the Chief Executive Officer, the Chairman of the Nominating and Corporate Governance Committee, or the Lead Independent Director or all non-management directors, as the case may be.

The General Counsel may, in his sole discretion and acting in good faith, provide copies of any such stockholder communication to any one or more directors and executive officers of the Company, except that in processing any stockholder communication addressed to the Lead Independent Director or the Executive Sessions of non-management directors, the General Counsel may not copy any member of management in forwarding such communication to the Lead Independent Director.

In late 2017 and early 2018, management communicated with several of the Company's largest institutional stockholders to seek feedback on the Company's corporate governance policies and procedures. As a result of this stockholder outreach, on March 14, 2018, the Board of Directors adopted the Second Amended and Restated Bylaws of the Company, as further amended on April 30, 2018, which amend the Company's previous bylaws to generally allow a stockholder to propose amendments to the Company's bylaws for approval by the stockholders at an annual or special meeting of the stockholders. Amendments to the Company's bylaws must be submitted in compliance with the Company's policies and procedures for stockholder communications, and are subject to approval by the stockholders by the affirmative vote of a majority of all votes entitled to be cast by the stockholders on the matter. See "Stockholder Communications" and "Submission of Stockholder Proposals."

Elections of the Board of Directors are conducted in accordance with the Company's Charter, bylaws and the laws of the state of Maryland and provide that directors are to be elected at a meeting of the Company's stockholders by a majority of the votes cast in an uncontested election and by a plurality of votes cast in a contested election. Under the Company's bylaws and Corporate Governance Principles, if in any uncontested election of directors, a director nominee does not receive a majority of votes cast "for" his or her election, such director nominee shall promptly tender his or her resignation for consideration by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee will then promptly evaluate all relevant factors relating to the election results, including, but not limited to: (i) the underlying reasons why a majority of affirmative votes was not received (if ascertainable); (ii) the director's background, experience and qualifications; (iii) the director's length of service on the Board of Directors and contributions to the Company; and (iv) whether the director's service on the Board of Directors is consistent with applicable regulatory

requirements, listing standards, the Company's Corporate Governance Principles and the corporate governance guidelines of independent voting advisory services such as Institutional Shareholder Services.

Subject to any applicable legal or regulatory requirements, the Nominating and Corporate Governance Committee shall, within ninety (90) days from the date of the stockholder vote, decide whether to accept the resignation, reject the resignation or, if appropriate, conditionally reject the resignation and retain the director in office only if the underlying causes of the votes cast "against" the director can be promptly and completely cured. A full explanation of the Nominating and Corporate Governance Committee's decision will be promptly publicly disclosed in a periodic or current report filed with the Securities and Exchange Commission. Any director who tenders his or her resignation pursuant to this principle and any non-independent director will not participate in the deliberations and decisions made hereunder. In addition, a director shall tender his or her resignation for consideration by the Nominating and Corporate Governance Committee if such director's principal occupation or business association changes substantially during his or her tenure as a director.

Bow Street has notified the Company of its intent to nominate six (6) persons for election to the Board of Directors at the Annual Meeting in opposition to the nominees recommended by our Board of Directors. As a result, the election of directors at the Annual Meeting will be a contested election, in which directors will be elected by a plurality of votes cast.

The Audit Committee of the Board of Directors, on behalf of the Board of Directors, serves as an independent and objective party to monitor and provide general oversight of the Company's financial accounting and reporting process, selection of critical accounting policies, system of internal control, internal audit function, audit process for monitoring compliance with laws and regulations and the Company's standards of business conduct. The Audit Committee performs these oversight responsibilities in accordance with its charter.

The Company's management has primary responsibility for preparing the Company's financial statements and the Company's financial reporting process, including its system of internal control over financial reporting. The Company's independent registered public accountants, PricewaterhouseCoopers LLP, are responsible for expressing opinions on the conformity of the Company's 2018 audited financial statements to accounting principles generally accepted in the United States of America and the effectiveness of the Company's internal control over financial reporting as of December 31, 2018. The Audit Committee discussed with the Company's independent registered public accountants the overall scope and plans for its audits. The Audit Committee met with the Company's independent registered public accountants, with and without management present, to discuss the results of their examinations, their evaluations of the Company's internal control over financial reporting, and the overall quality of the Company's financial reporting.

The foregoing Audit Committee Report does not constitute soliciting material and shall not be deemed filed or incorporated by reference into any other Company filing under the Securities Act of 1933, as amended, or Exchange Act, except to the extent the Company specifically incorporates this Audit Committee Report by reference therein. Each of the members of the Audit Committee is independent as defined under the standards of the NYSE and the SEC, and meets all other requirements of such exchange and of such rules of the SEC.

The Company is continuing to pursue a comprehensive strategic initiative (the "Strategic Plan") which includes the following strategic objectives:

The Company's Strategic Plan represents a major step in the transformation of the Company's portfolio. The Company believes that the opportunity to invest in multi-family development properties at higher returns on cost will position the Company to potentially produce higher levels of net operating income than if the Company were to purchase only stabilized multi-family properties at market returns. However, the Company anticipates that income from its multi-family properties will increase slowly over time as its development projects underway are placed in service. The Company continued to implement the Strategic Plan throughout 2018.

During 2018, the Company continued its further progress toward the strategic objectives set forth in the Strategic Plan. Specifically, the Company executed on the following key accomplishments:

In 2018, we sought a stockholder say-on-pay advisory vote regarding executive compensation, and approximately 97.9% of the votes cast were in favor of our executive compensation. The Compensation Committee viewed this 97.9% stockholder approval as being strongly supportive of the actions undertaken by the Compensation Committee in 2017 and 2018. The Compensation Committee believes its compensation actions in 2018 aligned the Company's executive compensation plans with stockholder

expectations. We currently intend to continue to seek an annual stockholder say-on-pay advisory vote regarding executive compensation.


Executive Compensation Objectives		• Attracting, motivating and retaining key talent;
		• Tying compensation to the achievement of key short- and long-term objectives, including the Company's Core FFO per share, Core Adjusted FFO per share, and individual objectives, in the case of the annual cash incentive program, and absolute and relative total shareholder return ("TSR"), in the case of the long-term incentive program; and
		• Aligning management's interests with those of stockholders.
Factors Guiding Compensation Decisions		• Performance against pre-established short- and long-term objectives aligned with the Strategic Plan;
		• Stockholder feedback;
		• General market pay and governance practices; and
		• Mitigating compensation risk.
Summary of 2018 Compensation Program for Mr. DeMarco, our Chief Executive Officer		• Total compensation opportunities targeted at levels that are generally comparable to target total compensation levels for the chief executive officer of the Peer Group REITs (as defined below in the Compensation Discussion & Analysis under the heading "Process for Determining Compensation");
		• 80% of the annual cash incentive plan award based on pre-determined Company performance objectives, which align compensation with key annual financial (e.g., Core FFO and Core Adjusted FFO), and the remaining 20% based on individual and strategic achievements;
		• 75% of target long-term equity incentive awards allocated to performance-based long-term incentive plan ("LTIP") Units, granted under a multi-year, outperformance plan (the "2018 OPP"), under which the full awards will only be earned if, over the three-year performance period, the Company achieves a thirty-six percent (36%) absolute TSR and if the Company is at or above the 75th percentile of TSR versus the equity office REITs in the NAREIT Equity Office Index. Fifty percent (50%) of earned awards are subject to an additional two-year ratable service-vesting period; and
		• 25% of target long-term equity incentive awards allocated to time-Based LTIP Units that cliff-vest at the end of three years.

The Compensation Committee believes that the Company's overall executive compensation program incorporates many compensation elements that are considered best practices, including:

In addition, the Compensation Committee and the Board of Directors have committed to adopt, promptly upon effectiveness of final SEC and NYSE rules under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, a clawback policy for executive officers.

Role of the Compensation Consultant. In 2018, the Compensation Committee retained FW Cook as its independent Compensation Consultant. The Compensation Committee retains its compensation consultant to assist with structuring the Company's various compensation programs and determining appropriate levels of salary, annual cash incentive plan and other compensatory awards payable to the Company's executive officers and key employees. In 2018, FW Cook assisted on all relevant matters, including assisting with respect to: (i) assessing the Company's and management's performance relative to the Peer Group REITs; (ii) market ranges for salaries, annual cash incentive and long-term incentive compensation opportunities; (iii) compensation and governance practices relative to ISS and Glass Lewis policy guidelines; and (iv) structuring annual and long-term incentive compensation plans for management.

Determination of Compensation Consultant's Objectivity. The Compensation Committee recognizes that it is essential to receive objective advice from its outside compensation consultant. FW Cook was engaged by the Compensation Committee to act as an independent outside consultant to the Compensation Committee. The Compensation Committee closely examines the safeguards and steps that FW Cook takes to ensure that its executive compensation consulting services are objective. The Compensation Committee takes into consideration that:

FW Cook performed only executive, board and other compensation-related services for the Compensation Committee, and did not perform, directly or indirectly through an affiliate, any other services for the Company in 2018. Based on a consideration of factors deemed relevant to the Compensation Committee regarding FW Cook, including without limitation the independence factors specified in Section 303A.05 of the NYSE Listed Company Manual, including the nature of the services

provided, the amount of the compensation consultant's fees, its policies and procedures to prevent conflicts of interest, its business or personal relationships with our directors and executive officers, and its stock ownership in us, the Compensation Committee concluded that FW Cook is independent and that the work that they perform for the Compensation Committee has not raised any conflict of interest.

For its competitive analysis to assist the Committee in developing pay opportunities for 2018, FW Cook used a peer group consisting of the following fourteen office and diversified REITs: Brandywine Realty Trust, Columbia Property Trust, Corporate Office Properties Trust, Inc., Cousins Properties, Douglas Emmett, Inc., Empire State Realty Trust, Equity Commonwealth, Gramercy Property Trust, Highwoods Properties, Inc., Hudson Pacific Properties, Lexington Realty Trust, Paramount Group, Inc., Piedmont Office Realty Trust, and Washington REIT (collectively, the "Peer Group REITs"). The Compensation Committee used this analysis to evaluate the competitiveness of base salary, target annual cash incentive plan award, equity awards and target total compensation opportunities for the named executive officers, including the assessment of individual components of compensation. The Compensation Committee did not target a specific percentile of the Peer Group REITs for any compensation determinations but used the compensation data from Peer Group REITs as a factor in determining the appropriateness of compensation amounts generally.

The Compensation Committee, with assistance from the Compensation Consultant, and based upon the recommendations of the Chief Executive Officer with respect to the other named executive officers, determines the appropriate combination of cash and equity-based compensation to pay to the Company's executives and establishes performance metrics for annual cash incentive plan awards in consideration of its primary objectives with respect to executive compensation. In determining the appropriate mix of such compensation and the appropriate amounts of any discretionary components, the Compensation Committee considers the Compensation Consultant's competitive analyses of the Company's overall compensation arrangements. The Chief Executive Officer is responsible for the strategic direction and long-term planning for the Company and oversees the day to day performance of the other named executive officers. As such, the Compensation Committee believes that the input of the Chief Executive Officer is necessary information for it to evaluate the performance of the other named executive officers and make recommendations for their compensation packages. While the Compensation Committee considers the recommendations of the Chief Executive Officer with respect to his own compensation, the Chief Executive Officer does not participate in the Compensation Committee's determination of his own compensation and the Compensation Committee's determinations with respect to the Chief Executive Officer's compensation are not based on such recommendations.

The performance of the Company's named executive officers in office at the end of 2018 was evaluated at the end of 2018 (in the first quarter of 2019, after all financial information relative to the 2018 performance metrics for the annual cash incentive plan awards had been determined based on the Company's annual report on Form 10-K for the year ended December 31, 2018) by the Compensation Committee, with assistance from the Compensation Consultant, to determine performance relative to the 2018 performance metrics for the annual cash incentive plan awards. The Compensation Committee did not make any compensation determinations for Mr. Krug in 2018 (other than pursuant to his separation agreement), as Mr. Krug's employment as Chief Financial Officer was terminated effective February 21, 2018 prior to the Compensation Committee's deliberations on 2018 compensation matters.

For 2018, the Company's executive compensation program consisted of the following elements: (1) annual base salary; (2) annual cash incentive plan award; and (3) awards of performance-based and service-based LTIP Units of the Operating Partnership.

The allocation of each component of executive compensation was determined by the Compensation Committee, based upon its review of the Peer Group REIT data compiled by its Compensation Consultant and input from the Chief Executive Officer. Pursuant to the authority vested in the Compensation Committee set forth in its charter, it has complete discretion with respect to the compensation of the named executive officers.

Base Salaries. Base salaries are the fixed component of total compensation, and are established at levels the Compensation Committee deems appropriate for the function each executive officer performs. Base salaries are reviewed annually and with assistance from the Compensation Consultant and may be adjusted upward by the Compensation Committee from time to time. The table below sets forth the base salaries for the named executive officers in 2017 and 2018:


Executive Officer	2017 Base Salary		2018 Base Salary
Michael J. DeMarco	$	800,000		$	800,000
Marshall B. Tycher	$	800,000		$	800,000
David J. Smetana		N/A		$	450,000
Ricardo Cardoso	$	440,000		$	450,000
Gary T. Wagner	$	400,000		$	450,000
Mitchell E. Rudin	$	800,000		$	800,000
Robert Andrew Marshall	$	450,000		$	450,000

The Compensation Committee determined that 2018 base salaries for Messrs. DeMarco and Mr. Tycher would remain the same as their 2017 base salaries. When Mr. Smetana was hired in February 2018, the Compensation Committee established his base salary at $450,000, which is what the Compensation Committee deemed an appropriate and competitive level for the Chief Financial Officer of the Company. The Compensation Committee increased base salaries for Messrs. Cardoso, Wagner, and Marshall to $450,000, based on their assessment of competitive market base salaries, as well as internal parity among similarly-situated executives at the Company. The Compensation Committee did not consider any changes to Mr. Rudin's base salary in 2018, and Mr. Rudin's employment with the Company was terminated effective June 5, 2018. Mr. Marshall's employment with the Company was terminated effective October 31, 2018.

Annual Cash Incentive Plan Compensation. The Company's policy of awarding annual cash incentive plan awards is designed to specifically relate executive pay to Company and individual performance and to provide financial rewards for the achievement of substantive Company objectives.

The Compensation Committee adopted and the Board of Directors approved an annual cash incentive plan for the named executive officers for 2018, which was designed to directly support the Company's short-term goals in furtherance of the Strategic Plan.

For 2018, the Compensation Committee established annual cash incentive award opportunities for each named executive officer as a percentage of base salary, which awards were fixed by the terms of their respective employment agreements, as follows:

The Compensation Committee did not establish an annual cash incentive plan award opportunity for Mr. Rudin in 2018 and Mr. Rudin's employment with the Company was terminated effective June 5, 2018. The determination of 2018 annual cash incentive plan awards for the named executive officers was based 80% on Company performance measures and 20% on the Compensation Committee's assessment of individual performance. The 2018 Company performance measures approved by the Compensation Committee and ratified and adopted by the Board of Directors were as follows:

Target Core FFO per share was set by the Compensation Committee at the midpoint of the Core FFO per share guidance published by the Company in February 2018. The Target Core FFO and Target Core Adjusted FFO for 2018 were lower than the Target Core FFO and Target Core Adjusted FFO goals and actual performance for 2017 based on the reduction of the properties in the Company's portfolio resulting from the disposition of 30 office properties and developable land in 2018 for gross sales proceeds of $385.1 million pursuant to the Strategic Plan. The deployment of proceeds from those dispositions to repay outstanding debt of the Company and investment in multi-family residential acquisitions and development were not expected to contribute to FFO in 2018.

In March 2019, after the filing of the Company's Annual Report on Form 10-K for the year-ended December 31, 2018, the Compensation Committee assessed the performance of the named executive officers in 2018 relative to the above 2018 performance measures for the Company and made the following determination:

Core FFO per share was $1.83 per share, between threshold and target performance.

Core Adjusted FFO per share for 2018 was $1.05 per share, exceeding the maximum performance goal by $0.05 per share.

The discretionary component of each executive's 2018 performance awards was determined by the Compensation Committee based on the Committee's assessment of each executive's achievements in 2018 and contribution to the progress made in furthering the Company's long-term business strategy, including substantial completion of the disposition of non-core assets and development and lease-up of multi-family residential properties in furtherance of the Strategic Plan. The total 2018 cash incentive plan payouts for each of the named executive officers under the cash incentive plan were as follows:

Long-Term Incentives. The Company utilizes long-term incentive compensation in the form of service-based and performance-based equity awards to focus executives on the long-term performance of the Company, retain key executives, to align their interests with those of our stockholders, and to promote the success and enhance the value of the Company. The Compensation Committee, together with the Compensation Consultant, designed the long-term incentives for the named executive officers to be strongly tied to objective, quantifiable long-term performance metrics in line with current trends and recognized corporate governance "best practices."

2018 Long-Term Incentive Grants. In April 2018, the Compensation Committee adopted and the Board of Directors approved the grant of long-term incentive plan ("LTIP") awards to the management teams of the Company and Roseland, including all of the Company's executive officers (the "2018 LTIP Awards"). The design of the program was similar to the design of the LTIP Awards granted to the management team of the Company in 2016 and 2017. All of the 2018 LTIP Awards were in the form of LTIP Units and were made under the stockholder approved Mack-Cali Realty Corporation 2013 Incentive Stock Plan (the "2013 Plan").

As with the 2016 and 2017 equity awards, the Compensation Committee determined to award a significant portion of the 2018 LTIP Awards in the form of performance-based awards, pursuant to the 2018 Outperformance Plan adopted by the Company's Board of Directors, consisting of a multi-year, performance-based equity compensation plan and related forms of award agreements (the "2018 OPP"), to better align executive and stockholder interests by tying executive performance to TSR. For Messrs. DeMarco and Tycher, approximately seventy-five percent (75%) of the 2018 LTIP Awards were in the form of a performance-based award (the "2018 PBV LTIP Units") under the 2018 OPP. The remaining approximately twenty-five percent (25%) of the 2018 LTIP Awards for Messrs. DeMarco and Tycher were in the form of a time-based award that will cliff vest after three years on April 20, 2021 (the "2018 TBV LTIP Units"). For all other named executive officers, fifty percent (50%) of the 2018 LTIP was Awards were in the form of 2018 PBV LTIP Units and fifty percent (50%) of the 2018 LTIP Awards were in the form of 2018 TBV LTIP Units.

The 2018 OPP is designed to align the interests of senior management to relative and absolute TSR performance of the Company over a three-year performance period from April 20, 2018 through April 19, 2021. The senior management team that received 2018 LTIP Awards under the 2018 OPP includes seven of the Company's executive officers in 2018, including all of the named executive officers

other than Mitchell Rudin. Participants in the 2018 OPP will only earn the full awards if, over the three-year performance period, the Company achieves a thirty-six percent (36%) absolute TSR and if the Company is in the 75th percentile of TSR performance versus the equity office REITs in the NAREIT Equity Office Index.

Participants in the 2018 OPP have the opportunity to vest in 2018 PBV LTIP Units that ultimately may be settled in common stock of the Company according to the following schedules, with linear interpolation for performance between levels:

If the designated performance objectives are achieved, 2018 PBV LTIP Units are also subject to subsequent time-based vesting requirements, with 50% of earned 2018 PBV LTIP Units vesting at the end of the performance period on April 19, 2021, and the remaining 50% of earned 2018 PBV LTIP Units vesting 25% each on April 19, 2022 and April 19, 2023.

The named executive officers of the Company received the following 2018 LTIP Awards in the amounts set forth in the table below. The Compensation Committee determined to increase the grant date fair value of Mr. DeMarco's target 2018 LTIP Award by $500,000, as compared to his 2017 LTIP Award, in recognition of his successful transition from Chief Operating Officer to Chief Executive Officer during 2017 and the additional responsibilities he assumed without the appointment of a successor Chief Operating Officer. The Compensation Committee did not issue 2018 LTIP Awards to Mr. Rudin and Mr. Rudin's employment with the Company was terminated effective June 5, 2018:

LTIP Units were issued on April 20, 2018, but will remain subject to forfeiture depending on the extent that the 2018 LTIP Awards vest. The number of LTIP Units to be issued initially to recipients of the 2018 PBV LTIP Awards is the maximum number of LTIP Units that may be earned under the awards. The number of LTIP Units that actually vest for each award recipient will be determined at the end of the performance measurement period. TSR for the Company and for the Index over the

three-year measurement period and other circumstances will determine how many LTIP Units vest for each recipient; if they are fewer than the number issued initially, the balance will be forfeited as of the performance measurement date.

Prior to vesting, recipients of LTIP Units will be entitled to receive per unit distributions equal to one-tenth (10%) of the regular quarterly distributions payable on a common unit of limited partnership interest in the Operating Partnership (a "Common Unit"), but will not be entitled to receive any special distributions. Distributions with respect to the other nine-tenths (90%) of regular quarterly distributions payable on a Common Unit will accrue but shall only become payable upon vesting of the LTIP Unit. After vesting of the 2018 TBV LTIP Units or the end of the measurement period for the 2018 PBV LTIP Units, the number of LTIP Units, both vested and unvested, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on a Common Unit.

LTIP Units are designed to qualify as "profits interests" in the Operating Partnership for federal income tax purposes. As a general matter, the profits interests characteristics of the LTIP Units mean that initially they will not be economically equivalent in value to a Common Unit. If and when events specified by applicable tax regulations occur, LTIP Units can over time increase in value up to the point where they are equivalent to Common Units on a one-for-one basis. After LTIP Units are fully vested, and to the extent the special tax rules applicable to profits interests have allowed them to become equivalent in value to Common Units, LTIP Units may be converted on a one-for-one basis into Common Units. Common Units in turn have a one-for-one relationship in value with shares of the Company's common stock, and are redeemable on a one-for-one basis for cash or, at the election of the Company, shares of the Company's common stock.

The 2018 LTIP Awards granted to Mr. DeMarco are in lieu of, and shall supersede and replace, the long-term incentive plan awards for calendar year 2018 contemplated by paragraph 4(b) of his original employment agreement with the Company dated June 5, 2015.

2016 Outperformance Plan ("2016 OPP"). In 2016, the Compensation Committee granted a significant portion of executive officer long-term incentives in the form of performance-based LTIP Units (the "2016 PBV LTIP Units"), which could be earned based on the Company's relative and absolute TSR measured over the three-year from March 8, 2016 through March 7, 2019. The Company's relative and absolute TSR performance were both below the threshold levels, resulting in no 2016 PBV LTIP Units being earned under the 2016 OPP.

Severance and Change-in-Control Payments. Each of our named executive officers for 2018 was subject to an employment agreement with the Company. These agreements provide for certain severance benefits in the event of termination of their employment in certain circumstances. These benefits are commonly offered among peer companies, and therefore enable us to attract and retain key talent. In particular, they ensure the retention of our named executive officers when considering potential transactions which may create uncertainty as to their continued employment. The employment agreements for each of the named executive officers that were in effect in 2018 provided for severance payments in the event of involuntary termination without cause or constructive termination for good reason and double trigger severance benefits in the event of a change in control that are generally 1.5 times the sum of annual base salary and bonus for the named executive officer. See "Executive Compensation—Employment Contracts; Potential Payments Upon Termination or Change in Control" for a summary of the terms and conditions of the severance provisions in the employment agreements of the named executive officers.

On June 14, 2018, the Company entered into a separation and general release agreement with Mr. Rudin pursuant to which Mr. Rudin's employment by the Company was terminated effective as of June 5, 2018. On October 31, 2018, the Company, through Roseland, entered into a separation and consulting agreement with Mr. Marshall pursuant to which Mr. Marshall's employment by Roseland

was terminated on October 31, 2018 and he provided consulting services through March 31, 2019. See "Executive Compensation—Employment Contracts; Potential Payments Upon Termination or Change in Control" for a summary of the terms and conditions of the severance provisions in the separation agreements with Messrs. Rudin and Marshall.

401(k) Savings Plan. The Company maintains a tax-qualified defined contribution plan for the benefit of all its eligible employees, including the named executive officers. The provisions and features of the plan apply to all participants in the plan, including the named executive officers. Eligible employees may elect to defer from one percent up to 60 percent of their annual compensation on a pre-tax basis to the 401(k) Plan, subject to certain limitations imposed by federal law. The amounts contributed by employees are immediately vested and non-forfeitable. The Company may make discretionary matching or profit sharing contributions to the 401(k) Plan on behalf of eligible participants in any plan year. Participants are always 100 percent vested in their pre-tax contributions and will begin vesting in any matching or profit sharing contributions made on their behalf after two years of service with the Company at a rate of 20 percent per year, becoming 100 percent vested after a total of six years of service with the Company. All contributions are allocated as a percentage of compensation of the eligible participants for the Plan year. The assets of the 401(k) Plan are held in trust and a separate account is established for each participant. A participant may receive a distribution of his or her vested account balance in the 401(k) Plan in a single sum or in installment payments upon his or her termination of service with the Company. In 2018, there were $886,000 in discretionary matching or profit sharing contributions made by the Company to the plan on behalf of all employees, including $66,000 on behalf of the named executive officers.

Other Compensation. The Company offers limited perquisites to certain of its executive officers in the form of vehicle allowances. See note 3 under "Executive Compensation—Summary Compensation Table." The Company does not offer qualified or non-qualified defined benefit plans to its executive officers or employees, nor does it offer non-qualified defined contribution plans.

The Company has Equity Ownership Guidelines for the Chief Executive Officer. The Compensation Committee believes the Equity Ownership Guidelines further align the interests of the Chief Executive Officer with stockholder value and requires each executive to own an aggregate of 250,000 shares of the Company's Common Stock ("Shares") or any derivatives that may be settled in shares of the Company's common stock ("Derivatives"), in any combination of Shares or Derivatives as determined in the sole discretion of the executive. The Chief Executive Officer currently satisfies these ownership guidelines.

The Board of Directors has adopted a policy that provides that executive officers, employees, and directors may not acquire securities issued by the Company or any of its affiliates using borrowed funds, may not use margin in respect of securities issued by the Company or any of its affiliates, may not pledge securities issued by the Company or any of its affiliates as collateral, and may not engage in hedging or other transactions with respect to their ownership of securities issued by the Company or its affiliates, each of which the Board of Directors believes would be inconsistent with the purposes and intent of the stock ownership guidelines applicable to directors and the Chief Executive Officer.

In setting compensation, the Compensation Committee considers the risks to our stockholders and to achievement of our goals that may be inherent in our compensation programs. At the direction of the Compensation Committee, we conducted a risk assessment of our compensation programs, including our executive compensation programs. The Compensation Committee reviewed and discussed the findings of this assessment and concluded that our compensation programs are designed with the appropriate balance of risk and reward in relation to our overall business strategy and do not incent employees to take unnecessary or excessive risks. Although a significant portion of our executive's compensation is performance-based and "at-risk," we believe our executive compensation plans are appropriately structured and are not reasonably likely to result in a material adverse effect on the Company. We considered the following elements of our executive compensation plans and policies when evaluating whether such plans and policies encourage our executives to take unreasonable risks:

In sum, we believe our executive compensation program is structured so that (i) we maintain a conservative risk profile that and aims to achieve strong stockholder returns and long-term results; (ii) we avoid the type of disproportionately large short-term incentives that could encourage executives to take risks that may not be in our long-term interests; (iii) we provide incentives to manage for long-term performance; and (iv) a considerable amount of wealth of our executives is tied to our long-term success. We believe this combination of factors encourages our executives to manage the Company in a prudent manner. The Compensation Committee specifically considered compensation risk implications during its deliberations on annual cash incentive plan awards and performance metrics for all executive officers.

The Compensation Committee has reviewed the Compensation Discussion and Analysis and discussed that Analysis with management. Based on its review and discussions with management, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 and the Company's proxy statement relating to the Annual Meeting of stockholders

to be held on June 12, 2019. This report is provided by the following independent directors, who comprise all of the members of the Compensation Committee:

Executive Compensation and Option Committee Interlocks and Insider Participation

The Compensation Committee consists of Nathan Gantcher, Chairman, Kenneth M. Duberstein, Alan G. Philibosian and Vincent Tese. No member of the Compensation Committee was at any time in 2018 or at any other time an officer or employee of the Company, and no member had any relationship with the Company requiring disclosure as a related-person transaction in the section "Certain Relationships and Related Transactions." No executive officer of the Company has served on the board of directors or compensation committee of any other entity that has or has had one or more executive officers who served as a member of our Board of Directors or Compensation Committee at any time in 2018.

The following table sets forth certain information concerning the compensation of all persons who served as chief executive officer or chief financial officer during 2018, and the three most highly compensated executive officers of the Company other than those persons who served as chief executive officer or chief financial officer in 2018 (collectively, the "Named Executive Officers") for the Company's fiscal years ended December 31, 2018, 2017 and 2016, respectively:

(1): The 2018 annual cash incentive plan awards were paid on March 6, 2019 in respect of 2018 performance based on the achievement of the 2018 performance metrics. See "Compensation Discussion and Analysis—Components of Compensation in 2018—Cash Incentive Plan Compensation."
(2): Amounts shown represent the grant date fair value of LTIP Unit awards granted to each of the named executive officers in 2018, as calculated in accordance with Accounting Standards Codification Topic 718 ("ASC 718"). For a discussion of the Company's assumptions and accounting treatment of its equity compensation awards, see Note 2: Significant Accounting Policies—Stock Compensation, to the Company's financial statements beginning on page 82 of the Company's Annual Report on Form 10-K for the year ended December 31, 2018. In 2018, the grant date fair value of LTIP Unit awards subject to time-based vesting conditions for Messrs.

(1): Represents LTIP Unit awards subject to performance based vesting conditions. The grant date fair value of $8.82 per LTIP Unit was calculated using the Monte Carlo method, disregarding for this purpose the estimate of forfeitures related to time based vesting conditions, and is consistent with the estimate of aggregate compensation cost to be recognized over the service period determined in accordance with ASC 718 in accordance with instruction 8 to Item 402(d) of Regulation S K. The LTIP Units subject to performance based vesting may be earned after the end of the three year performance period ending April 19, 2021, with 50 percent of the LTIP Units based on the achievement of absolute TSR and 50 percent based on achievement of relative TSR. 50 percent of earned performance-based LTIP Units vest on April 19, 2021, and the remainder vest in two equal installments of 25 percent each on April 19, 2022 and April 19, 2023. See "Compensation Discussion and Analysis—Components of Compensation in 2018—Long Term Incentives."
(2): Represents LTIP Unit awards subject to time-based vesting conditions with a grant date fair value per Unit of $16.95, the closing price of the Company's common stock as reported on the New York Stock Exchange on April 19, 2018, disregarding for this purpose the estimate of forfeitures related to time-based vesting conditions. The LTIP Units subject to time-based vesting shall vest after three years on April 19, 2021. See "Compensation Discussion and Analysis—Components of Compensation in 2018—Long-Term Incentives."
(3): Mr. Marshall's employment was terminated effective October 31, 2018. Pursuant to the Marshall Separation Agreement, Mr. Marshall forfeited all of the LTIP Units granted to him in 2018.

On April 20, 2018, the Company granted LTIP awards to senior management of the Company, including the Company's executive officers (the "2018 LTIP Awards"). All of the 2018 LTIP Awards were in the form of LTIP Units and constitute awards under the 2013 Plan. For Messrs. DeMarco and Tycher, approximately seventy-five percent (75%) of the 2018 LTIP Awards were in the form of a performance-based award (the "2018 PBV LTIP Units") under the Company's Outperformance Plan (the "2018 OPP") adopted by the Company's Board of Directors, consisting of a multi-year, performance-based equity compensation plan and related forms of award agreement. The remaining

approximately twenty-five percent (25%)of the 2018 LTIP Awards for Messrs. DeMarco and Tycher were in the form of a time-based award that will cliff vest after three years on April 19, 2021 (the "2018 TBV LTIP Units"). For all other executive officers, approximately fifty percent (50%) of the 2018 LTIP Awards were in the form of 2018 PBV LTIP Units and approximately fifty percent (50%) of the 2018 LTIP Awards were in the form of 2018 TBV LTIP Units.

The 2018 OPP is designed to align the interests of senior management to relative and absolute performance of the Company over a three-year performance period from April 20, 2018 through April 19, 2021. Participants in the 2018 OPP will only earn the full awards if, over the three-year performance period, the Company achieves a thirty-six percent (36%) absolute TSR and if the Company's TSR is in the 75th percentile of performance as compared to the office REITs in the NAREIT index.

If the designated performance objectives are achieved, 2018 PBV LTIP Units are also subject to time-based vesting requirements, with 50% of earned 2018 PBV LTIP Units vesting at the end of the performance period on April 19, 2021, and the remaining 50% of earned 2018 PBV LTIP Units vesting in two equal installments of 25% each on April 19, 2022 and April 19, 2023.

LTIP Units will remain subject to forfeiture depending on the extent that the 2018 LTIP Awards vest. The number of LTIP Units to be issued initially to recipients of the 2018 PBV LTIP Awards is the maximum number of LTIP Units that may be earned under the awards. The number of LTIP Units that actually vest for each award recipient will be determined at the end of the performance measurement period. TSR for the Company and for the Index over the three-year measurement period and other circumstances will determine how many LTIP Units vest for each recipient; if they are fewer than the number issued initially, the balance will be forfeited as of the performance measurement date.

Prior to vesting, recipients of LTIP Units will be entitled to receive per unit distributions equal to one-tenth (10 percent) of the regular quarterly distributions payable on a common unit of limited partnership interest in the Operating Partnership (a "common unit"), but will not be entitled to receive any special distributions. Distributions with respect to the other nine-tenths (90 percent) of regular quarterly distributions payable on a common unit will accrue but shall only become payable upon vesting of the LTIP Unit. After vesting of the 2018 TBV LTIP Units or the end of the measurement period for 2018 PBV LTIP Units, holders of LTIP Units, both vested and unvested, pending satisfaction of the time-based vesting requirements, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on a common unit.

Employment Contracts; Potential Payments Upon Termination or Change in Control

The following discussion includes descriptions of the material terms of employment agreements and certain incentive equity award agreements between the Company and Messrs. DeMarco, Tycher, Smetana, Cardoso and Wagner. It also includes descriptions of the material terms of separation agreements between the Company and Messrs. Rudin and Marshall.

Michael J. DeMarco Employment Agreement. On June 5, 2015, the Company entered into an employment agreement with Mr. DeMarco (the "2015 DeMarco Employment Agreement"). The term of the 2015 DeMarco Employment Agreement expired on December 31, 2018. On March 13, 2019, the Company entered into a new employment agreement with Mr. DeMarco, effective as of January 1, 2019 (the "2019 DeMarco Employment Agreement"), that replaced the 2015 DeMarco Employment Agreement.

Pursuant to the 2019 DeMarco Employment Agreement, the Company has agreed to employ Mr. DeMarco, and Mr. DeMarco has agreed to be employed by the Company, as the Chief Executive Officer of the Company, for a period commencing on January 1, 2019 and ending on December 31, 2022 (the "Term"), unless Mr. DeMarco's employment is earlier terminated in accordance with the 2019 DeMarco Employment Agreement.

Pursuant to the 2019 DeMarco Employment Agreement, Mr. DeMarco will be entitled to the following compensation and benefits:

In addition, Mr. DeMarco will be entitled to customary employee benefits under the Company's health and welfare plans.

The 2019 DeMarco Employment Agreement provides for certain severance payments to Mr. DeMarco, or his beneficiaries, upon death, disability, termination by the Company without cause, and termination by Mr. DeMarco for good reason during the Term or a change in control period. Under the 2019 DeMarco Employment Agreement:

Under the terms of the 2019 DeMarco Employment Agreement, upon a termination on account of death or disability, Mr. DeMarco (or his beneficiaries in the case of death) will be entitled to receive his accrued and unpaid base salary, expense reimbursement and benefits under the Company's health and welfare plans through the termination date, plus a prorated portion of the annual bonus payable for the year of such termination.

In the event of a termination of Mr. DeMarco's employment without cause or by Mr. DeMarco for good reason during the Term or thereafter during a change in control period, subject to Mr. DeMarco signing a release in customary form, he will be entitled to the same benefits in the event of a termination due to death or disability, as described below, plus a lump sum cash payment equal to (i) if such termination occurs during the Term and not during a change in control period, 2.0 times the sum of (x) his annual base salary immediately prior to the termination date and (y) his target bonus for the year during which termination occurs, or (ii) if such termination occurs during or after the expiration the Term and during a change in control period, 3.0 times the sum of (x) his annual base salary immediately prior to the termination date and (y) his target bonus for the year during which termination occurs. In addition, Mr. DeMarco will be entitled to COBRA coverage premiums for up to 18 months after such termination.

Under the terms of the 2019 DeMarco Employment Agreement, (i) the expiration of the Term will not be considered a termination of Mr. DeMarco's empment by the Company with or without cause or the resignation of Mr. DeMarco for good reason or otherwise, and (ii) in the event a reorganization, spin-off, split-off or similar transaction (or series of transactions) involving the Company is consummated and, following the consummation of such transaction, Mr. DeMarco continues to be employed as chief executive officer of any successor entity (or the ultimate parent entity thereof) that

expressly assumes the Company's obligations under the 2019 DeMarco Employment Agreement, the consummation of such transaction (or series of transactions) will not be considered a termination of Mr. DeMarco's employment by the Company with or without cause or the resignation of Mr. DeMarco for good reason or otherwise and, in each such case, Mr. DeMarco's employment will not be considered to have been constructively terminated for any reason unless he resigns for good reason in accordance with the 2019 DeMarco Employment Agreement.

Pursuant to the 2019 DeMarco Employment Agreement, Mr. DeMarco will be subject to certain restrictive covenants, including non-competition and non-solicitation covenants during the period of his employment with the Company and for 12 months after termination of his employment in circumstances in which he is entitled to receive severance benefits under the 2019 DeMarco Employment Agreement.

Michael J. DeMarco Class AO LTIP Award Agreement. Pursuant to the terms of the 2019 DeMarco Employment Agreement, the Company has entered into the Class AO LTIP Award Agreement with Mr. DeMarco, which provides for the grant to Mr. DeMarco of 625,000 Class AO LTIP Units of limited partnership interests in the Operating Partnership (the "Class AO LTIP Units") pursuant to the 2013 Plan and the Second Amended and Restated Agreement of Limited Partnership of the Operating Partnership (as amended, restated and supplemented from time to time, the "Partnership Agreement"). The Class AO LTIP Units were awarded to Mr. DeMarco to incentivize him to enter into the 2019 DeMarco Employment Agreement after the expiration of the 2015 DeMarco Employment Agreement. The Board of Directors believes that retaining Mr. DeMarco's continuing services as Chief Executive Officer is critical to the successful completion of the Company's ongoing strategic transformation, which Mr. DeMarco has led since he joined the Company in June 2015. To further incentivize Mr. DeMarco's performance under his new employment agreement, the Class AO LTIP Units are structured as the economic equivalent of stock options, such that Mr. DeMarco will only realize any value from the Class AO LTIP Units if the Company's stock price appreciates during the term of the 2019 DeMarco Employment Agreement and the price vesting conditions (described below) are met prior to March 13, 2023. Class AO LTIP Units are intended to qualify as "profits interests" for federal income tax purposes and generally allow the recipient to realize value only to the extent the Common Stock trades at a price per share that exceeds $21.46, the closing price of the Common Stock, as reported on the NYSE, on the date of grant, subject to any vesting conditions applicable to the award.

Under the Class AO LTIP Award Agreement, the Class AO LTIP Units issued to Mr. DeMarco are subject to the following vesting conditions:

The value of vested Class AO LTIP Units is realized through conversion of the Class AO LTIP Units into common units of limited partnership interests of the Operating Partnership (the "Common Units"). The number of Common Units into which vested Class AO LTIP Units may be converted is determined based on the quotient of (i) the excess of the closing price of the Common Stock, as

reported on the NYSE, on the conversion date over $21.46, divided by (ii) the closing price of the Common Stock, as reported on the NYSE, on the conversion date. Vested Class AO LTIP Units may be converted into Common Units within ten years of the date of grant.

Under the Class AO LTIP Award Agreement, any Class AO LTIP Units held by Mr. DeMarco upon termination of his employment will be treated as follows:

Under the Class AO LTIP Award Agreement, upon the occurrence of a change in control prior to March 13, 2023, if Mr. DeMarco's employment with the Company or any of its subsidiaries has not been terminated by the Company for cause prior to such change in control, then satisfaction of the vesting conditions described above will be ascertained on the date of such change in control based on the price per share of Common Stock (plus the value per share of Common Stock of any other consideration, as determined by the Board of Directors or the Compensation Committee) received by the Company's stockholders in connection with such change in control, and any previously unvested Class AO LTIP Units issued to Mr. DeMarco that do not become vested as of the date of such change in control as described above will automatically be forfeited, cancelled and become null and void, without payment of any consideration therefor, as of the date of such change in control.

Under the Class AO LTIP Award Agreement, the terms "cause," "change in control," "change in control period," "disability" and "good reason" are substantially the same as defined in the 2019 DeMarco Employment Agreement. The term "retirement" is defined as the termination of Mr. DeMarco's employment for any reason other than death, disability, termination by the Company for cause or termination by Mr. DeMarco for good reason on or after the date that (i) Mr. DeMarco has attained 60 years of age and (ii) Mr. DeMarco has served as an employee of the Company for at least ten (10) years.

Notwithstanding the foregoing, the vesting of any Class AO LTIP Units upon the termination of Mr. DeMarco's employment or upon a change in control will be conditioned upon Mr. DeMarco (i) executing, and not revoking within the applicable period specified in the 2019 DeMarco Employment Agreement, a release of claims in the form required under the 2019 DeMarco Employment Agreement, and (ii) complying, during the period that any Class AO LTIP Units issued to Mr. DeMarco remain unvested, with the restrictive covenants, including, without limitation, the restrictions on engaging in competitive activities, soliciting service providers or clients, and utilizing confidential information, contained in the 2019 DeMarco Employment Agreement.

Mr. DeMarco will generally accrue special income allocations in respect of a Class AO LTIP Unit equal to 10% of the income allocated in respect of a Common Unit into which a Class AO LTIP Unit may be converted. Upon conversion of any Class AO LTIP Units to Common Units, Mr. DeMarco will be entitled to receive in respect of each such Class AO LTIP Unit, on a per unit basis, a special cash

distribution equal to 10% of the distributions received by a holder of an equivalent number of Common Units during the period from the grant date of the Class AO LTIP Units through the date of conversion.

Marshall B. Tycher Employment Agreement. On April 26, 2017, the Company, through its wholly-owned subsidiary Roseland Residential Trust, entered into an employment agreement with Mr. Tycher (the "Tycher Employment Agreement"), which replaced Mr. Tycher's previous employment agreement, dated October 23, 2012.

The Tycher Employment Agreement provides for certain severance payments to Mr. Tycher, or his beneficiaries, upon death, disability, termination by the Company without cause, termination by Mr. Tycher for good reason during the term of his employment or within two years of a change in control. Under the Tycher Employment Agreement, the terms "cause," "change in control," "change in control period," "disability" and "good reason" are substantially the same as defined in the 2019 DeMarco Employment Agreement.

Under the terms of the Tycher Employment Agreement, upon a termination on account of death or disability, Mr. Tycher (or his beneficiaries in the case of death) will receive a lump sum payment consisting of accrued and unpaid base salary, expense reimbursement and benefits under the Company's health and welfare plans through the termination date, any earned but unpaid annual bonus for the previous year, plus a prorated portion of the annual bonus payable for the year of such termination. Upon a termination by the Company without cause or by Mr. Tycher for good reason during the term of the Tycher Employment Agreement or thereafter during a change in control period, Mr. Tycher will be entitled to the same benefits as in the event of a termination due to death or disability, as well as (i) a lump sum cash payment equal to one and one-half (1.5) times the sum of (a) his annual base salary immediately prior to the termination date, and (b) his target bonus for the year during which termination occurs and (ii) COBRA payments for up to 18 months after termination.

Under the terms of the Tycher Employment Agreement, any time on or after July 1, 2018, Mr. Tycher may elect to step down as Chairman of Roseland and continue as non-executive chairman for a reduced salary of $400,000 annually (the "Transition"), provided that any such Transition will not trigger any severance benefits payable under the Tycher Employment Agreement.

Employment Agreements with David J. Smetana, Gary T. Wagner and Ricardo Cardoso. On January 26, 2018, the Company entered into employment agreements with Messrs. Smetana, Wagner and Cardoso (each, an "Officer Employment Agreement" and, collectively, the "Officer Employment Agreements"). Each of the Officer Employment Agreements has an initial term expiring on December 31, 2020.

Each of the Officer Employment Agreements provides for the following compensation and benefits:

Under each of the Officer Employment Agreements, upon a termination of employment on account of death or disability, the officer (or his beneficiaries in the case of death) will receive payments (payable as and when such amounts would have been payable had the officer's employment not ended) consisting of accrued and unpaid base salary, expense reimbursement and benefits under the Company's health and welfare plans through the termination date, any earned but unpaid annual bonus for the previous year, plus a prorated portion of the annual bonus payable for the year of such termination. Upon a termination of employment by the Company without cause or by the officer for good reason during the term of the applicable Officer Employment Agreement or thereafter during a change in control period, subject to the officer signing a release in the form attached to each of the Officer Employment Agreements, the officer will be entitled to the same benefits as in the event of a

termination due to death or disability, plus a lump sum cash payment equal to one and one-half (1.5) times the sum of the officer's (i) annual base salary immediately prior to the termination date and (ii) target annual bonus for the year of such termination. Under the Officer Employment Agreements, the terms "cause," "change in control," "change in control period," "disability" and "good reason" are substantially the same as defined in the 2019 DeMarco Employment Agreement.

Long-Term Incentive Plan Award Agreements. In connection with the grants of time-based LTIP Units (the "Time-Based LTIP Units") to certain of the Company's named executive officers (each, a "Grantee") in 2016, 2017, 2018 and 2019, the Company has entered into a 2016 Time-Based Long-Term Incentive Plan Award Agreement, a 2017 Time-Based Long-Term Incentive Plan Award Agreement, a 2018 Time-Based Long-Term Incentive Plan Award Agreement, and a 2019 Time-Based Long Term Incentive Plan Award Agreement with each Grantee (collectively, the "Time-Based LTIP Agreements").

Under the Time-Based LTIP Agreements, any unvested Time-Based LTIP Units held by a Grantee upon termination of his employment will be treated as follows:

Under the Time-Based LTIP Agreements, notwithstanding the acceleration of vesting of any Time-Based LTIP Units held by the Grantee, as described above, the Grantee will not have the right to transfer or redeem such Time-Based LTIP Units until such dates as of which such Time-Based LTIP Units would have become vested pursuant to the three-year vesting period under the applicable Time-Based LTIP Agreement, absent the Grantee's death, disability, retirement or Qualified Termination, as applicable.

Notwithstanding the foregoing, the vesting of any Time-Based LTIP Units upon the termination of a Grantee's employment will be conditioned upon such Grantee (i) executing, and not revoking or breaching prior to the vesting time period under the applicable Time-Based LTIP Agreement, a release of claims in a form required by the Compensation Committee, and (ii) complying with any restrictive covenants, including any restrictions in competitive activities, soliciting service providers or clients, or utilizing confidential information, contained in the Grantee's employment agreement.

Under the Time-Based LTIP Agreements, the terms "cause," "change of control," "disability" and "good reason" have the same meaning as in the applicable employment agreement. The term "change of control period" is defined as the period commencing on the earlier of (i) the date that a change of control occurs or (ii) the date that the Company enters into a definitive agreement with respect to a transaction, the consummation of which would constitute a change of control (provided it is actually consummated), and in either case ending on the second anniversary of the change of control. The term "retirement" is defined as the termination of the Grantee's employment for any reason other than death, disability, termination by the Company for cause or termination by the Grantee for good reason on or after the date that the Grantee has attained 60 years of age and has served as an employee of the Company for at least ten (10) years.

In connection with the grants of performance-based LTIP Units (the "Performance-Based LTIP Units") to certain of the Company's named executive officers (each, a "Grantee") in 2016, 2017, 2018 and 2019, the Company has entered into a 2016 Performance-Based Long-Term Incentive Plan Award Agreement, a 2017 Performance-Based Long-Term Incentive Plan Award Agreement, a 2018 Performance-Based Long-Term Incentive Plan Award Agreement and a 2019 Performance-Based Long-Term Incentive Plan Award Agreement with each Grantee (collectively, the "Performance-Based LTIP Agreements").

Under the Performance-Based LTIP Agreements, any unvested Performance-Based LTIP Units held by a Grantee upon termination of his employment will be treated as follows:

Under the Performance-Based LTIP Agreements, upon the occurrence of a change of control, if (i) a Grantee's employment is terminated due to a Qualified Termination during a change of control

period or (ii) the Company or its successor does not assume, convert, or replace the Performance-Based LTIP Units with a security with substantially the same rights, privileges, preferences of the Performance-Based LTIP Units, then all unvested Performance-Based LTIP Units held by the Grantee will immediately vest.

Notwithstanding the foregoing, the vesting of any Performance-Based LTIP Units upon the termination of a Grantee's employment or upon a change of control will be conditioned upon the Grantee (i) executing, and not revoking or breaching prior to the vesting time period under the applicable Performance-Based LTIP Agreement, a release of claims in a form required by the Compensation Committee, and (ii) complying with any restrictive covenants, including any restrictions in competitive activities, soliciting service providers or clients, or utilizing confidential information, contained in the applicable employment agreement.

Under the Performance-Based LTIP Agreements, the terms "cause," "change of control," "disability" and "good reason" have the same meaning as in the applicable employment agreement. The term "change of control period" is defined as the period commencing on the earlier of (i) the date that a change of control occurs or (ii) the date that the Company enters into a definitive agreement with respect to a transaction, the consummation of which would constitute a change of control (provided it is actually consummated), and in either case ending on the second anniversary of the change of control. The term "retirement" is defined as the termination of the Grantee's employment for any reason other than death, disability, termination by the Company for cause or termination by the Grantee for good reason on or after the date that the Grantee has attained 60 years of age and has served as an employee of the Company for at least ten (10) years.

Rudin Separation Agreement. On June 14, 2018, the Company entered into a separation and general release agreement with Mitchell Rudin (the "Rudin Separation Agreement"), pursuant to which Mr. Rudin's employment with the Company was terminated, effective as of June 5, 2018. Under the terms of the Rudin Separation Agreement, Mr. Rudin received the following separation payments:

The Rudin Separation Agreement reflects that, as previously disclosed, certain equity awards previously issued to Mr. Rudin, including 66,667 time-vesting options, 6,750 restricted stock units and 56,325.82 performance share units, vested in full as of June 5, 2018, in accordance with their terms.

In addition, during the Consulting Period, Mr. Marshall received a monthly consulting fee of $22,500.

The Marshall Separation and Consulting Agreement provides that Mr. Marshall will continue to vest during the Consulting Period in all of the 22,120 Time-Based Long-Term Incentive Plan Awards originally issued in March 2016 (the "Continued 2016 Time-Based LTIP Awards") and 28,880 of the 35,697 Performance-Based Long-Term Incentive Plan Awards originally issued in March 2016 (the "Continued 2016 Performance-Based LTIP Awards" and, together with the Continued 2016 Time-Based LTIP Awards, the "Continued 2016 LTIP Awards"). Pursuant to the Marshall Separation and Consulting Agreement, the Continued 2016 LTIP Awards would vest on the earliest to occur of (i) Mr. Marshall's death, (ii) the termination of Mr. Marshall's consulting services by the Company for any reason other than for cause (as defined in the Marshall Separation and Consulting Agreement) prior to March 31, 2019 or (iii) March 8, 2019 (such earliest date, the "Vesting Date"), subject to Mr. Marshall's continuous performance of the consulting services through the applicable Vesting Date. All other equity awards previously issued to Mr. Marshall, including the remaining 6,817 Performance-Based LTIP Awards originally issued in March 2016, 4,449 Time-Based Long-Term Incentive Plan Awards originally issued in April 2017, 13,473 Performance-Based Long-Term Incentive Plan Awards originally issued in April 2017, 11,799 Time-Based Long-Term Incentive Plan Awards originally issued in April 2018, and 22,676 Performance-Based Long-Term Incentive Plan Awards originally issued in April 2018, expired and were forfeited and cancelled, effective as of the Termination Date.

The Marshall Separation and Consulting Agreement further provided that on the earliest to occur of (i) March 11, 2019, (ii) five (5) business days after Roseland receives written notice of Mr. Marshall's death, or (iii) the date on which Mr. Marshall's consulting services are terminated by the Company for any reason other than for cause, the Company would purchase from Mr. Marshall all of the Continued 2016 LTIP Awards. On March 11, 2019, the Company repurchased all of the Continued 2016 LTIP Awards for an aggregate purchase price in cash equal to $1,068,450, which amount represents the product of (x) the average closing price of the Company's common stock over the five trading days ending March 8, 2019 of $20.95 and (y) 51,000 LTIP Units. The Marshall Separation and Consulting Agreement also contains customary releases of claims and non-disparagement provisions.

The following table sets forth information regarding amounts payable to Messrs. DeMarco, Tycher, Smetana, Cardoso and Wagner pursuant to their respective employment agreements in connection with a termination of employment or change in control, calculated as if the applicable termination event occurred on December 31, 2018. The actual amount paid to Mr. Krug upon his separation from the Company was included in the Potential Payments Upon Termination or Change In Control table in the Company's definitive proxy statement for the 2018 Annual Meeting, which was filed with the SEC on April 30, 2018 and is incorporated herein by reference. The actual amounts paid to Messrs. Rudin and Marshall were pursuant to their respective separation agreements described above. The separation

agreements for Messrs. Marshall and Krug provided for partial accelerated vesting of their performance-based LTIP Awards in consideration of Mr. Marshall's transition services during the term of his consulting agreement and Mr. Krug's continued service as Chief Financial Officer through the filing of the Company's annual report on Form 10-K for the year end December 31, 2017. Except for the termination events set forth in the table below, as of December 31, 2018, the named executive officers were not entitled to any other payments upon a change in control.

Information in the table above reflects the actual amounts paid to Mr. Marshall pursuant to his separation agreement.

Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act") and Item 402(u) of Regulation S-K promulgated by the SEC thereunder requires the Company to disclose the median of the annual total compensation of all employees, excluding the chief executive officer, and the ratio of the median of the annual total compensation of all employees to the annual total compensation of the chief executive officer. In 2018, we identified the median employee using our employee population on December 31, 2018 and based on each employee's total compensation, using the same elements of compensation reportable in the Summary Compensation Table for Named Executive Officers as the "consistently applied compensation measure" under Item 402(u) of Regulation S-K. We did not perform adjustments to the compensation paid to part-time employees to calculate what they would have been paid on a full-time basis. We did not make any assumptions, adjustments, or estimates other than annualizing the compensation for any permanent (full-time or part-time) employees that were not employed by us for all of 2018. We then calculated the 2018 total compensation for the 2018 median employee using the same methodology as required for the 2018 Summary Compensation Table.

In 2018, the total compensation of our median employee, excluding the chief executive officer, as calculated using Summary Compensation Table requirements, was $81,285; the chief executive officer's total compensation was $6,111,999, as reported in the Summary Compensation Table; and the ratio of the chief executive officer's total compensation for 2018 to the 2018 total compensation for the median employee was 75:1.

The following table summarizes information, as of December 31, 2018, relating to equity compensation plans of the Company (including individual compensation arrangements) pursuant to which equity securities of the Company are authorized for issuance.

(1): The only plan included in the table that was adopted without stockholder approval was the Directors' Deferred Compensation Plan. See Note 15: Mack-Cali Realty Corporation Stockholders' Equity and Mack-Cali Realty, L.P.'s Partners' Capital—Deferred Stock Compensation Plan For Directors, to the Company's financial statements beginning on page 113 of the Company's Annual Report on Form 10-K for the year ended December 31, 2018.
(2): Includes 67,289 shares of unvested restricted common stock and 800,000 unexercised options.
(3): Weighted average exercise price of outstanding options; excludes restricted common stock and LTIP units.
(4): The Directors' Deferred Compensation Plan does not limit the number of stock units issuable thereunder, but applicable SEC and NYSE rules restricted the aggregate number of stock units issuable thereunder to one percent (1%) of the General Partner's outstanding shares when the plan commenced on January 1, 1999.

Directors' Fees. In 2018, each non-employee director was paid an annual fee of $65,000, plus $1,500 for attendance at, or telephonic participation in, any board or committee meeting. The Chairmen of each of the Audit Committee, the Executive Committee, the Nominating and Corporate Governance Committee and the Compensation Committee were paid an additional annual fee of $15,000 in 2018, and the Lead Independent Director was paid an additional annual fee of $40,000 in 2018. Each director also was reimbursed for expenses incurred in attending board and committee meetings. For fiscal year 2018, the Company's non-employee directors received directors' fees or fee equivalents (see "Compensation of Directors—Directors' Deferred Compensation Plan" below) in the amounts set forth in the table below.

Directors' Deferred Compensation Plan. Pursuant to the Amended and Restated Directors' Deferred Compensation Plan, originally effective as of January 1, 1999 (the "Directors' Deferred Compensation Plan"), each non-employee director is entitled to defer all or a specified portion of the annual fee to be paid to such director. The account of a director who elects to defer such compensation under the Directors' Deferred Compensation Plan is credited with the hypothetical number of stock units, calculated to the nearest thousandths of a unit, determined by dividing the amount of cash compensation deferred on the quarterly deferral date by the closing market price of the Common Stock on such quarterly deferral date. Any stock dividend declared by the Company on Common Stock results in a proportionate increase in units in the director's account as if such director held shares of Common Stock equal to the number of units in such director's account. Payment of a director's account may only be made in a lump sum in shares of Common Stock equal to the number of units in a director's account after either the director's service on the Board of Directors has terminated or there has been a change in control of the Company. On December 9, 2008, the Directors' Deferred Compensation Plan was amended and restated to conform to the requirements of Section 409A of the Code. In 2018, Nathan Gantcher, David S. Mack, Alan G. Philibosian, Irvin D. Reid, and Vincent Tese elected to receive a portion of their respective cash fees earned in 2018 in the form of deferred stock units under the Directors' Deferred Compensation Plan.

Directors' Stock Incentive Plans. The Company has one equity compensation plan pursuant to which equity compensation awards to non-employee members of the Board of Directors may be made: the 2013 Plan. On June 13, 2018, each non-employee member of the Board of Directors was granted shares of restricted Common Stock with an approximate grant-date fair value of $90,000 under the 2013 Plan. These restricted shares will vest on June 13, 2019.

The following proposal gives our stockholders the opportunity to vote to approve or not approve, on an advisory basis, the compensation of our named executive officers as disclosed in the "Compensation Discussion and Analysis" and "Executive Compensation" sections of this proxy statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and our compensation philosophy, policies and practices with respect to our named executive officers. We are providing this vote as required by Section 14A of the Exchange Act, which was added to the Exchange Act by Section 951 of the Dodd-Frank Act. We provide this vote annually based on an election made by our stockholders at our 2017 annual meeting of stockholders, and we will ask our stockholders to vote on the frequency of this advisory vote again at the Annual Meeting. The Board of Directors believes that the overall design and function of the Company's executive compensation program is appropriate and effective in aligning the interests of management and the Company's stockholders and that management is properly incentivized to manage the Company in a prudent manner. Accordingly, we are asking our stockholders to vote "FOR" the adoption of the following resolution:

Although the vote is non-binding, the Board of Directors and the Compensation Committee will review the voting results in connection with their ongoing evaluation of the Company's executive compensation program.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR ADVISORY APPROVAL OF THE RESOLUTION SET FORTH ABOVE.

PROPOSAL NO. 3
RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM

PricewaterhouseCoopers LLP served as the Company's independent registered public accountants for the fiscal year ended December 31, 2018, and has been appointed by the Audit Committee to continue as the Company's independent registered public accountants for the fiscal year ending December 31, 2019. In the event that ratification of this appointment of the Company's independent registered public accountants is not approved at the Annual Meeting, then the appointment of the Company's independent registered public accountants will be reconsidered by the Audit Committee. Unless marked to the contrary, proxies received will be voted for ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accountants for the fiscal year ending December 31, 2019.

A representative of PricewaterhouseCoopers LLP is expected to be present at the Annual Meeting. The representative will have an opportunity to make a statement and will be able to respond to appropriate questions.

Your ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accountants for the fiscal year ending December 31, 2019 does not preclude the Board of Directors from terminating its engagement of PricewaterhouseCoopers LLP and retaining a new independent registered public accounting firm if it determines that such an action would be in the best interests of the Company. If the Company elects to retain a new independent registered public accounting firm, such independent registered public accountants will be another "Big 4" accounting firm.

The Company was billed for professional services rendered in 2018 by PricewaterhouseCoopers LLP, the details of which are disclosed below.

Pursuant to its charter, the Audit Committee has the sole authority to appoint or replace the Company's independent registered public accountants (subject, if applicable, to stockholder ratification). The Audit Committee is directly responsible for the compensation and oversight of the work of the Company's independent registered public accountants (including resolution of disagreements between management and the Company's independent registered public accountants regarding financial reporting) for the purpose of preparing or issuing an audit report or related work. The Company's independent registered public accountants are engaged by, and report directly to, the Audit Committee.

The Audit Committee pre-approves all auditing services and permitted non-audit services (including the fees and terms thereof) to be performed for the Company by its independent registered public accountants, subject to the de minimis exceptions for non-audit services described in Section 10A(i)(1)(B) of the Exchange Act and SEC Rule 2-01(c)(7)(i)(C) of Regulation S-X, all of which are approved by the Audit Committee prior to the completion of the audit. In the event pre-approval for such auditing services and permitted non-audit services cannot be obtained as a result of inherent time constraints in the matter for which such services are required, the Chairman of the Audit Committee has been granted the authority to pre-approve such services, provided that the estimated cost of such services on each such occasion does not exceed $125,000, and the Chairman of the Audit Committee reports for ratification such pre-approval to the Audit Committee at its next scheduled meeting. The Audit Committee has complied with the procedures set forth above, and has otherwise complied with the provisions of its charter.

The aggregate fees and expenses incurred by the Company and its consolidated subsidiaries for fiscal years ended December 31, 2018 and 2017 for professional services rendered by PricewaterhouseCoopers LLP or its affiliates in connection with (i) the audit of the Company's annual financial statements; (ii) the review of the financial statements included in the Company's Quarterly Reports on Form 10-Q for the quarters ended March 31, June 30, and September 30; (iii) a consent issued in connection with a registration statement; and (iv) services provided in connection with statutory and regulatory filings or engagements, including attestation services required by Section 404 of the Sarbanes-Oxley Act of 2002, were $1,703,360 and $1,660,000, respectively.

The aggregate audit related fees and expenses incurred for the fiscal years ended December 31, 2018 and December 31, 2017 for assurance and related services rendered by PricewaterhouseCoopers LLP related to Roseland Residential Trust were $371,000 and $371,000, respectively.

The aggregate fees incurred by the Company for fiscal years ended December 31, 2018 and 2017 for professional services rendered by PricewaterhouseCoopers LLP for tax compliance, tax advice and tax planning were $231,000 and $224,500, respectively. These services consisted of reviewing the Company's tax returns.

There were no fees or expenses incurred by the Company for fiscal years ended December 31, 2018 and 2017 for other services rendered by PricewaterhouseCoopers LLP.

Assuming a quorum is present, the affirmative vote of a majority of the votes cast at the Annual Meeting, either in person or by proxy, is required for approval of this proposal. Abstentions will have no effect on the outcome of this proposal. Because the ratification of the appointment of the independent auditors is a discretionary item, we do not anticipate receiving any broker non-votes with respect to this proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2019.
