INFORMATION ABOUT US We are a fully-integrated, self-administered and self-managed real estate investment trust, or "REIT." We own and operate a portfolio predominantly comprised of class A office and office/flex properties located primarily in the Northeast, as well as commercial real estate leasing, management, acquisitions, development and construction businesses. Mack-Cali Realty, L.P. conducts substantially all of the operations relating to such properties. As of May 15, 1999, our portfolio consisted of 253 properties, aggregating approximately 28.0 million square feet, plus developable land. Included in our portfolio are 248 wholly-owned properties, aggregating approximately 27.0 million square feet, plus developable land. Our properties include (1) 155 office properties aggregating approximately 22.6 million square feet; (2) 80 office/flex properties (properties whose square footage predominantly consist of office space, a part of which is utilized as warehouse space) aggregating approximately 4.0 million square feet; (3) six industrial/ warehouse properties aggregating approximately 387,400 square feet; (4) two multi-family residential properties consisting of 453 units; (5) two stand-alone retail properties; and (6) three land leases. In addition, we also have ownership interests in unconsolidated joint ventures which own four office properties and one office/flex property, aggregating approximately 1.0 million square feet. We believe that our properties have excellent locations and access and that we effectively maintain and professionally manage them. As a result, we believe that our properties attract high quality tenants and achieve among the highest rental, occupancy and tenant retention rates within their markets. As of March 31, 1999, our properties were approximately 96.7 percent leased to over 2,400 tenants. Our properties are located in 12 states, primarily in the Northeast, and the District of Columbia. The principals of Cali Associates, the entity to whose business we succeeded in 1994, have been involved in the development, leasing, management, operation and disposition of commercial and residential properties in northern and central New Jersey for over 50 years. These individuals primarily have been focusing on office building development and acquisitions for the past 20 years. We and our predecessors have employed our current executive officers for an average of approximately 10 years. We and our predecessors have extensive development experience, having developed11.9 million square feet (or 44.4 percent) of our properties. Our strategy has been to focus on the acquisition, operation and development of office properties in markets and sub-markets where we are, or can become, a significant and preferred owner and operator. We will continue this strategy by expanding, through acquisitions or development, into markets and sub-markets where we have, or can achieve, similar status. We believe that the recent trend toward rising rental and occupancy rates in our markets and sub-markets continues to present significant opportunities for internal growth. We also may develop properties in our markets and sub-markets, particularly with a view towards the development of our vacant land holdings which principally are located adjacent to our existing properties. We believe that our extensive market knowledge provides us with a significant competitive advantage which is further enhanced by our strong reputation for, and emphasis on, delivering highly responsive, professional management services. 4 We also aim to maximize growth in our funds from operations and to enhance the value of our portfolio through effective management, acquisition and development strategies, including the following: - enhancing our reputation as a property operator of choice; - re-leasing space at higher effective rents with contractual rent increases; - emphasizing frequent communication with tenants to ensure first-class service at our properties; - maintaining and developing long-term relationships with our diverse tenant base; - implementing operating strategies to produce increased effective rental and occupancy rates and decreased concession and tenant installation costs; and - developing or redeveloping space for our diverse base of high credit tenants. Consistent with our business and growth strategies, in 1998 we acquired or placed in service 56 office and office/flex properties, aggregating approximately 4.9 million square feet, for an aggregate cost of approximately $686.6 million. During the same time period we also acquired ownership interests in unconsolidated joint ventures which own an aggregate of five properties totaling an aggregate of 1.0 million square feet for a net investment of approximately $66.5 million. We were incorporated under the laws of the State of Maryland on May 24, 1994. Our executive offices are located at 11 Commerce Drive, Cranford, New Jersey 07016 and our telephone number is (908) 272-8000. We have an internet website address at http://www.mack-cali.com. USE OF PROCEEDS We are registering the shares of common stock offered by this prospectus for the account of the selling shareholders identified in the section of this prospectus entitled "Selling Shareholders." All of the net proceeds from the sale of the common stock will go to the shareholders who offer and sell their shares of such stock. We will not receive any part of the proceeds from the sale of such shares. INDEMNIFICATION FOR SECURITIES ACT LIABILITIES Our articles of incorporation and bylaws contain certain provisions to indemnify our directors and officers against liability incurred by them as a result of their services as directors and/or officers. We have been informed that in the opinion of the Securities and Exchange Commission, our indemnification of our directors, officers or controlling persons for liabilities arising under the Securities Act of 1933, as amended, is against public policy as expressed in the Securities Act, and therefore is unenforceable. 5 SELLING SHAREHOLDERS The selling shareholders are persons listed in the table below who may receive shares of our common stock in exchange for their units of limited partnership interest in Mack-Cali Realty, L.P. and/or their warrants to purchase common units. We are registering for the 26 selling shareholders an aggregate of 1,369,902 common units that are redeemable for an equal number of shares of our common stock. The selling shareholders may redeem their common units for an equal number of shares of common stock in accordance with the terms described in this section of the prospectus. In connection with our acquisition of the property portfolio of Pacifica Holding Company, we issued 685,438 common units to five of the selling shareholders. In connection with our acquisition of a 49.9% interest in a joint venture with G&G Martco, we issued 218,105 common units to seven of the selling shareholders. In connection with our contractual expansion of 5551 West Talavi Boulevard, we issued 52,245 common units to 13 of the selling shareholders. In connection with our acquisition of 40 Richards Avenue, we issued 414,114 common units to one of the selling shareholders. Holders of common units may require Mack-Cali Realty, L.P. to redeem all or part of their common units for (1) cash, based upon the fair market value of an equivalent number of shares of common stock at the time of such redemption or (2) at our election, shares of common stock on a one-for-one basis. The selling shareholders may convert their common units into shares of common stock on a one-for-one basis after the one year anniversary date of the issuance of the common units. We may assume Mack-Cali Realty, L.P.'s obligation to redeem the common units in exchange for, at the election of Mack-Cali Realty, L.P., either cash or shares of common stock. However, we may not pay for such redemption with shares of common stock if, after giving effect to such redemption, any person would beneficially or constructively own shares in excess of the ownership limit described in "Restrictions on Transfer". The following table sets forth, as of May 15, 1999, (1) the name of each selling shareholder, (2) the number of shares of our common stock beneficially owned by each selling shareholder and underlying each of the selling shareholder's units of limited partnership interest, (3) the maximum number of shares of common stock which the selling shareholders can sell pursuant to this prospectus and (4) the number of shares of common stock underlying units that the selling shareholders would own if they sold all their shares registered by this prospectus. As of such date, we had not issued any shares of our common stock, including any such shares underlying the selling shareholders' units, to the selling shareholders. Each selling shareholder will receive all of the net proceeds from the sale of his or her shares of common stock offered by this prospectus. This offering will not affect the number of shares of common stock outstanding or the number of shares or percentage of ownership which persons, other than the selling shareholders, own. Because the selling shareholders may sell all or part of their shares of common stock pursuant to this prospectus and this offering is not being underwritten on a firm commitment basis, we cannot estimate the number and percentage of shares of common stock that the selling stockholders will hold at the end of the offering covered by this prospectus. 6 THE SELLING SHAREHOLDERS

8 PLAN OF DISTRIBUTION Once the selling shareholders have exchanged their common units for shares of common stock, the selling shareholders may from time to time offer and sell their shares of common stock offered by this prospectus. We have registered their shares for resale to provide them with freely tradable securities. However, registration does not necessarily mean that they will offer and sell any of their shares. OFFER AND SALE OF SHARES The selling shareholders, or their pledgees, donees, transferees or other successors in interest, may offer and sell their shares of common stock in the following manner: - on the New York Stock Exchange or other exchanges on which the common stock is traded at the time of sale; - in the over-the-counter market or otherwise at prices and at terms then prevailing or at prices related to the then current market price; or - in privately negotiated transactions. The selling shareholders, or their pledgees, donees, transferees or other successors in interest, may sell their shares of common stock in one or more of the following transactions: - a block trade in which the broker or dealer so engaged will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction; - a broker or dealer may purchase as principal and resell such shares for its own account pursuant to this prospectus; - an exchange distribution in accordance with the rules of the exchange; and - ordinary brokerage transactions and transactions in which the broker solicits purchasers. The selling shareholders may accept and, together with any agent of the selling shareholders, reject in whole or in part any proposed purchase of the shares of common stock offered by this prospectus. BROKERS AND DEALERS SELLING THROUGH BROKERS AND DEALERS. The selling shareholders may select brokers or dealers to sell their shares of common stock. Brokers or dealers that the selling shareholders engage may arrange for other brokers or dealers to participate in selling such shares. The selling shareholders may give such brokers or dealers commissions or discounts in amounts to be negotiated immediately before any sale. In connection with such sales, these brokers or dealers, any other participating brokers or dealers, and certain pledgees, donees, transferees and other successors in interest, may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act. In addition, any securities covered by this prospectus that qualify for sale pursuant to Rule 144 of the Securities Act may be sold under such rule rather than pursuant to this prospectus. SUPPLEMENTAL PROSPECTUS REGARDING MATERIAL ARRANGEMENTS. If and when a selling shareholder notifies us that he, she or it has entered into a material arrangement with a broker or dealer for the sale of his, her or its shares of common stock offered by this prospectus through a block trade, special offering, exchange or secondary distribution or a purchase by a broker or dealer, we will file a supplemental prospectus, if required, pursuant to Rule 424(c) under the Securities Act. The supplemental prospectus will provide: (1) the name(s) of each such selling shareholder(s) and of the participating broker-dealer(s); (2) the number of shares of common stock involved; (3) the price at which such shares were sold; (4) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable; (5) that such broker-dealer(s) did not conduct any investigation to 9 verify the information set out or incorporated by reference in this prospectus; and (6) other facts material to the transaction. COMMISSIONS. The selling shareholders will pay any sales commissions or other seller's compensation applicable to such transactions. SUPPLEMENTAL PROSPECTUS REGARDING SALES To the extent required, we will set forth in a prospectus supplement accompanying this prospectus or, if appropriate, in a post-effective amendment, the following information: (1) the amount of the shares of common stock to be sold; (2) purchase prices; (3) public offering prices; (4) the names of any agents, dealers or underwriters; and (5) any applicable commissions or discounts with respect to a particular offer. The selling shareholders and agents who execute orders on their behalf may be deemed to be "underwriters" as that term is defined in Section 2(11) of the Securities Act. A portion of any proceeds of sales and discounts, commissions or other seller's compensation may be deemed to be underwriting compensation for purposes of the Securities Act. COMPLIANCE WITH STATE SECURITIES LAWS We have not registered or qualified the shares of common stock offered by this prospectus under the laws of any country, other than the United States. In certain states, the selling shareholders may not offer or sell their shares of common stock unless (1) we have registered or qualified such shares for sale in such states; or (2) we have complied with an available exemption from registration or qualification. Also, in certain states, to comply with such states' securities laws, the selling shareholders can offer and sell their shares of common stock only through registered or licensed brokers or dealers. LIMITATIONS IMPOSED BY EXCHANGE ACT RULES AND REGULATIONS Certain provisions of the Securities Exchange Act of 1934, as amended, and the related rules and regulations will apply to the selling shareholders and any other person engaged in a distribution of shares of the common stock. Such provisions may (1) limit the timing of purchases and sales of any of the shares of common stock by the selling shareholders or such other person; (2) affect the marketability of such stock; and (3) affect the brokers' and dealers' market-making activities with respect to such stock. PAYMENT OF INCIDENTAL EXPENSES We will pay substantially all of the expenses related to the registration of the shares of common stock offered by this prospectus. We estimate such expenses to be approximately $41,336. 10 DESCRIPTION OF SECURITIES TO BE REGISTERED AUTHORIZED CAPITAL STOCK Pursuant to our articles of incorporation, we have the authority to issue 190,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share. At June 1, 1999, 58,432,601 shares of common stock were issued and outstanding, and no shares of preferred stock were issued and outstanding. COMMON STOCK VOTING, DIVIDEND AND OTHER RIGHTS. Each outstanding share of common stock entitles the holder to one vote on all matters presented to stockholders for a vote, subject to the provisions of our articles of incorporation regarding the restrictions on transfer of such stock, discussed in "Restrictions on Transfer" below. Holders of shares of common stock do not have any cumulative voting rights. This means that the holders of a majority of the outstanding shares of common stock can elect all of the directors then standing for election and the holders of the remaining shares will not be able to elect any directors. Holders of shares of common stock do not have preemptive rights to subscribe for any of our securities. All shares of common stock will, when issued, be duly authorized, fully paid, and nonassessable. We may pay dividends to the holders of shares of common stock if and when our board of directors declares such dividends out of legally available funds. RIGHTS UPON LIQUIDATION. Under Maryland law, our stockholders generally are not liable for our debts or obligations. Upon our liquidation, subject to the right of any holders of preferred stock to receive preferential distributions, each holder of common stock may participate pro rata in the assets remaining after payment of, or adequate provision for, all of our known debts and liabilities. Such debts and liabilities may arise from our status as general partner of Mack-Cali Realty, L.P. OWNERSHIP LIMIT. Under our articles of incorporation, with certain exceptions, no person may own, or be deemed to own by virtue of the attribution rules of the Internal Revenue Code of 1986, as amended, more than 9.8 percent of the value of our issued and outstanding shares of capital stock. See "Restrictions on Transfer" below. TRANSFER AGENT. ChaseMellon Shareholder Services, LLC is the registrar and transfer agent for our common stock. RESTRICTIONS ON TRANSFER OWNERSHIP LIMIT. For us to qualify as a real estate investment trust under the Internal Revenue Code, we must meet the following requirements concerning the ownership of outstanding shares of our capital stock: - five or fewer individuals (as defined in the Internal Revenue Code to include certain entities) may not collectively own, directly or indirectly, more than 50 percent of the value of our outstanding capital stock during the last half of a taxable year; and - at least 100 persons during at least 335 days of a taxable year or during a proportionate part of a shorter taxable year must beneficially own our capital stock. Further, under our articles of incorporation, subject to certain exceptions, no holder of shares of our capital stock may own, or be deemed to own by virtue of the attribution rules of the Internal Revenue Code, more than 9.8 percent by value of our outstanding capital stock. Such limit will be referred to in this prospectus as the "Ownership Limit." EXEMPTION FROM OWNERSHIP LIMIT. Our board of directors may exempt a person from the Ownership Limit if the board of directors or our tax counsel is satisfied that such ownership will not 11 then or in the future jeopardize our status as a real estate investment trust. To obtain such exemption, the intended transferee of shares of our capital stock must (1) give us written notice of the proposed transfer and (2) furnish such opinions of counsel, affidavits, undertakings, agreements and information as the board of directors may require no later than the 15th day before any transfer which could cause the intended transferee's direct or beneficial ownership of shares to exceed the Ownership Limit. If the board of directors decides that it is no longer in our best interests to continue to qualify as a real estate investment trust, then the restrictions on transferability and ownership will not apply. NULL AND VOID TRANSFERS. A transfer of shares of capital stock shall be null and void and the intended transferee of such shares will not acquire any rights in such shares if the transfer would: - create a direct or indirect ownership of shares of stock in excess of the Ownership Limit; - result in the shares of stock being owned by fewer than 100 persons; or - result in our being "closely held" within the meaning of Section 856(h) of the Internal Revenue Code. CERTIFICATE LEGEND REFERRING TO RESTRICTIONS. All certificates representing shares of our common stock will bear a legend referring to the restrictions described in the above section entitled "Restrictions on Transfer--Null and Void Transfer." REQUIRED DISCLOSURES BY STOCKHOLDERS. Every owner of more than five percent (or such lower percentage as the Internal Revenue Code or related regulations require) of our issued and outstanding shares of capital stock must give us written notice containing the information specified in our articles of incorporation no later than January 31 of each year. In addition, every stockholder must, upon our demand, provide in writing information that we may request to determine the effect of such stockholder's direct, indirect and constructive ownership of such shares on our status as a real estate investment trust. EFFECT OF OWNERSHIP LIMITS ON CONTROL OF OUR COMPANY. The ownership limitations set forth in this prospectus may prevent the acquisition of control of our company without the consent of the board of directors.
