FOR IMMEDIATE RELEASE

NEW JERSEY SPORTS AND EXPOSITION AUTHORITY APPROVES
MEADOWLANDS XANADU DEVELOPMENT AGREEMENT
The Mills Corporation/Mack-Cali Realty Corporation project will transform the
Meadowlands into the country’s foremost destination for sports, entertainment,
recreation and office facilities

East Rutherford, N.J., December 3, 2003 — A joint venture between affiliates of The Mills Corporation (NYSE: MLS) and Mack-Cali Realty Corporation (NYSE: CLI) today signed an agreement with the New Jersey Sports and Exposition Authority (NJSEA) for the redevelopment of the Continental Airlines Arena site and the construction of Meadowlands Xanadu, the 4.76 million-square-foot family entertainment, office and hotel complex to be built at the Meadowlands Sports Complex.

Work is to begin when all the necessary permits and approvals are obtained. The family entertainment component of Meadowlands Xanadu will open about two years after the groundbreaking. Meadowlands Xanadu will feature the nation’s first indoor Alpine ski resort and an indoor mini-Formula One style racing venue. Other planned uses include a minor-league baseball stadium, an extreme sports park, a grand movie palace and a small-format live entertainment venue. The Mills Corporation will lead the development of the family entertainment complex.

Mills Chairman and Chief Executive Officer Laurence C. Siegel said, “Meadowlands Xanadu will set a new standard for bringing lifestyle, recreation, sports and family entertainment offerings together in one location. Our team is excited to create this innovative destination, integrated with dramatic architectural and design elements, which will capture visitors’ imaginations and sense of adventure.”

Mack-Cali Realty Corporation will be the lead developer for the 2.2 million-square-foot office and hotel component of the project. Mitchell E. Hersh, Chief Executive Officer of Mack-Cali, said, “Mack-Cali has a long history of developing premier office properties. We’re confident that the high-quality office space and state-of-the-art hotel and conference center that we will build at Xanadu will attract top-tier businesses to the Meadowlands, benefiting both the complex and the Northern New Jersey region.” The office and hotel components of the project will consist of four 14-story, 440,000 square-foot class A office buildings and a 520-room hotel with conference facilities.

Kan Am, a Munich-based investment advisory company, will be an investment partner of The Mills Corporation in the project. “Meadowlands Xanadu is the premier development project in the United States, and Kan Am is delighted to participate in this great investment opportunity,” said James C. Braithwaite, President, Kan Am U.S. Inc.

The Meadowlands Xanadu project is expected to generate 20,000 permanent jobs in New Jersey — translating into $1.24 billion in personal income annually — and 19,000 construction and related jobs — equal to $1.17 billion in annual personal income. The project is estimated to produce $133 million annually in state and local tax revenue.

The Mills/Mack-Cali joint venture will pay a $160 million development rights fee at the start of construction for the family entertainment component of the development, when all permits and approvals are obtained.
