       On September 25, 2002, Boston Properties Limited Partnership (together
with its direct and indirect wholly-owned subsidiaries, "BPLP"), the operating
partnership subsidiary of Boston Properties, Inc. (the "Company"), completed the
acquisition of 399 Park Avenue, a 1.68 million square foot building in New York
City ("399 Park Avenue"), for a purchase price of $1.06 billion. The seller was
Citibank, N.A. The Company financed the acquisition in part with a $1.0 billion
unsecured bridge loan that matures in September 2003. The interest rate and loan
covenants with respect to the bridge loan are similar to those of the Company's
unsecured line of credit.

       399 Park Avenue occupies the entire block from Lexington Avenue to Park
Avenue, and from 53rd to 54th Streets in Midtown Manhattan. The building serves
as the corporate headquarters of Citigroup, which occupies approximately 40% of
the building. Other tenants include Lehman Brothers, Bingham McCutchen, Arnold &
Porter, Wilmer Cutler & Pickering, and JP Morgan Chase. The building is fully
leased, and more than 75% of the building is leased for terms in excess of ten

       The transaction was consummated through a newly-formed Delaware
limited liability company, of which BPLP is the managing member. The total
acquisition cost of approximately $1.06 billion, including purchase price and
closing costs, was funded in part through the $1.00 billion bridge loan. The
balance of the acquisition cost was paid in cash.
