INFORMATION ABOUT MACK-CALI REALTY CORPORATION We, Mack-Cali Realty Corporation, a Maryland corporation, are a fully-integrated, self-administered and self-managed real estate investment trust, or "REIT." We own predominantly Class A office and office/flex buildings generally located in the Northeast and Southwest. Mack-Cali Realty, L.P., a Delaware limited partnership, conducts substantially all of the operations relating to such properties. As of September 30, 1998, we owned and operated, directly or indirectly, 247 properties, plus developable land, aggregating approximately 27.6 million square feet. Our properties include 235 office and office/flex buildings totaling approximately 27.2 million square feet, six industrial/warehouse properties containing an aggregate of approximately 387,400 square feet, two multi-family residential properties consisting of 453 units, two stand-alone retail properties and two land leases. Our 235 office and office/flex properties are comprised of 156 office buildings containing an aggregate of 23.1million square feet and 79 office/flex buildings containing an aggregate of approximately 4.1 million square feet. We believe that our properties have excellent locations and access and are well-maintained and professionally managed. 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 September 30, 1998, over 2,300 tenants leased approximately 96.1 percent of the office, office/flex and industrial/warehouse properties. Our strategy is to acquire, develop and own 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, primarily through acquisitions, into markets and sub-markets where we have, or can achieve, similar status. Because rental and occupancy rates in office buildings in such markets and sub-markets continue to increase, we believe that such markets and sub-markets present significant opportunities for growth. We also may develop properties in such markets and sub-markets, particularly with a view towards potential utilization of certain vacant land recently acquired or on which we hold options. We believe that our extensive market knowledge gives us a significant competitive advantage, which is further enhanced by our strong reputation for and emphasis on delivering highly responsive management services, including direct and continued access to our senior management. Consistent with our growth strategy, in December 1997, we acquired 54 Class A office properties, aggregating approximately 9.2 million square feet, from The Mack Company and Patriot American Office Group. We acquired such properties for a total cost of approximately $1.1 billion. In connection with such transaction, (1) we became associated with respected names in the real estate business, including William L. Mack and Mitchell E. Hersh; (2) we changed our name from "Cali Realty Corporation" to "Mack-Cali Realty Corporation" and (3) Mack-Cali Realty, L.P. changed its name from "Cali Realty, L.P." to "Mack-Cali Realty, L.P." Also, in January 1997, we acquired 65 properties, aggregating approximately 4.1 million square feet, from the Robert Martin Company, LLC and its affiliates. We acquired all 65 properties for a total cost of approximately $450.0 million. In 1994, we succeeded to the business of Cali Associates. John J. Cali, Angelo R. Cali and Edward Leshowitz, the founders of Cali Associates, have been involved in the development, leasing, management, operation and disposition of commercial and residential properties in northern and central New Jersey for over 40 years. Our founders primarily have been focusing on office building development and acquisitions for the past fifteen years. In addition to our founders, we and our predecessors generally have employed our current executive officers for an average of approximately nine years. We and our 3 predecessors have built approximately four million square feet of office space, more than one million square feet of industrial facilities and over 5,500 residential units. 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. Our general information telephone number is (908) 272-8000. Our internet website address is 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 in those capacities. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the "Securities Act"), may be permitted to our directors, officers or controlling persons pursuant to the above provisions, we have been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act, and is therefore unenforceable. 4 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 ("Units") of limited partnership interest in Mack-Cali Realty, L.P. and/or their warrants to purchase common Units. As of the date of this prospectus, (1) 57 of the selling shareholders held an aggregate of 4,013,739 common Units that are redeemable for an equal number of shares of our common stock; (2) one of the selling shareholders held an aggregate of 27,132 Series A preferred Units that are convertible into 783,030 common Units and then redeemable for an equal number of shares of our common stock; (3) 50 of the selling shareholders held an aggregate of 223,124 Series B preferred Units that are convertible into 6,439,367 common Units and then redeemable for an equal number of shares of our common stock; and (4) 47 of the selling shareholders held warrants to purchase an aggregate of 2,000,000 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 prospectus. In connection with our acquisition of the property portfolios of The Mack Company and Patriot American Office Group on December 11, 1997, we issued 3,972,318 common Units, 27,132 Series A preferred Units, 223,124 Series B preferred Units and 48 warrants to purchase an aggregate of 2,000,000 common Units to 57 of the selling shareholders. When we acquired the property of Princeton Overlook Associates, L.P. on December 19, 1997, we issued 41,421 common Units to one selling shareholder. 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 each of the Series A preferred Units at any time into common Units at a conversion price of $34.65 per Unit, and after the one year anniversary date of the Series A preferred units' initial issuance, the selling shareholders may then convert the common Units received pursuant to such conversion into common stock on a one-for-one basis. The selling shareholders also may convert each of the Series B preferred Units into common Units at a conversion price of $34.65 per Unit, and after the one year anniversary date of the Series B preferred Units' initial issuance, the selling shareholders may then convert the common Units received pursuant to such conversion into common stock on a one-for-one basis, subject in certain circumstances to contractual agreements with us that such conversion into common stock not occur until the third anniversary date of the Series B preferred Units' initial issuance. The selling shareholders may exercise the warrants to purchase common Units at any time after the one year anniversary and prior to the five year anniversary of their date of issuance at an exercise price of $37.80 per Unit. 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 the date of this prospectus, the name of each selling shareholder, the number of shares of our common stock beneficially owned by each selling shareholder and underlying each of the selling shareholder's common Units, Series A preferred Units, Series B preferred Units and warrants to purchase common Units, and the maximum number of shares of common stock which the selling shareholders can sell pursuant to 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 or warrants, 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. 5 This offering will not affect the number of common stock equivalents outstanding or the number of shares or percentage of ownership which persons, other than the selling shareholders, beneficially 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

10 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 verify 11 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 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 $151,000. 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 December 1, 1998, 57,123,697 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 12 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 distributions 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 (the "Code"), 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 REIT under the 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 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 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 then or in the future jeopardize our status as a REIT. 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 REIT, 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 Code. 13 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 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 REIT. 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.
