Boston Properties Continues Efforts to Acquire Center

March 28, 2001

BOSTON, March 28 /PRNewswire/ -- As previously reported on February 8, 2001, , Inc. (NYSE: BXP), a real estate investment trust, has acquired a significant interest in Skyline Holdings LLC. Skyline signed a contract on February 7, 2001 to acquire Citigroup Center in from Dai-Ichi Life Investment Properties, Inc. The acquisition of Citigroup Center, a 1.6 million square foot building in Midtown , is expected to close in April 2001.

It continues to be Boston Properties' intent to enter into a joint venture agreement pursuant to which Allied Partners, a private family-owned real estate investment company, would participate in the acquisition of the Citigroup Center on terms currently being negotiated with Allied. However, litigation recently filed against Allied and its principals, including Eric and Richard Hadar, in connection with an unrelated real estate partnership which owns a building at 1 East , New York, may interfere with the proposed joint venture. Boston Properties is not named in the lawsuit and the Citigroup Center acquisition is not at issue in the litigation. If the proposed joint venture with Allied cannot be put in place, Boston Properties intends to complete the acquisition of the Citigroup Center through its controlling interest in Skyline, in accordance with the contract with Dai-Ichi as currently in effect.
