ACQUISITION OF ASSETS. ACQUISITION OF 399 PARK AVENUE 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 years. 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. This report contains forward-looking statements within the meaning of the Federal securities laws. You should exercise caution in interpreting and relying on forward-looking statements because they involve known and unknown risks, uncertainties and other factors which are, in some cases, beyond the Company's control and could materially affect actual results, performance or achievements.
