MACK-CALI TO ACQUIRE 101 HUDSON STREET IN JERSEY CITY
—Acquisition of Trophy Property to Enhance Strong Presence Along the
Jersey City Waterfront—

Cranford, New Jersey—November 29, 2004—Mack-Cali Realty Corporation (NYSE: CLI) today announced that two of its subsidiaries have entered into a contract to acquire all the interests in 101 Hudson Street, a 1.2 million square-foot class A office tower on the Jersey City waterfront. The 42-story building, which also includes a four-story parking garage, will be purchased for $329 million. The transaction is expected to close in the first quarter 2005.

101 Hudson Street is 97.0% leased to seven tenants, including Merrill Lynch, AIG and Lehman Brothers.

Mitchell E. Hersh, president and chief executive officer of Mack-Cali, commented, “101 Hudson Street is a premier property with an impressive tenant roster and stable occupancy, and we’re especially pleased to acquire this asset at an attractive price.” He added, “With the acquisition of this trophy building, Mack-Cali further enhances its position as the dominant owner of class A office space on the Jersey City waterfront.”

Upon completion of the transaction, Mack-Cali will own over 4.3 million square feet of class A office space along the Jersey City waterfront, representing over 25% of the submarket’s total class A office space. The Company also manages an additional 1.2 million square feet of class A office space in the submarket.

101 Hudson Street offers excellent access to mass transportation—with nearby PATH and ferry service to downtown and midtown Manhattan and Hudson-Bergen Light Rail service to surrounding New Jersey communities—as well as unobstructed views of the Manhattan skyline.
