                              COMPANY BACKGROUND

        Boston Properties is a fully integrated, self-administered and
        self-managed real estate investment trust that develops, redevelops,
        acquires, manages, operates and owns a diverse portfolio of office,
        industrial and hotel properties. The Company is one of the largest
        owners and developers of Class A office properties in the United States,
        concentrated in four core markets - Boston, Midtown Manhattan,
        Washington DC, and San Francisco.

        On June 23, 1997, Boston Properties successfully completed its initial
        public offering. The offering and the underwriters over-allotment option
        closed on the same date resulting in 36,110,000 shares being sold at
        $25.00 per share for a total offering of $902,750,000. On January
        30,1998, the Company closed a follow-on offering of 23,000,000 shares
        (including the underwriters' over-allotment) at $35.125 per share for a
        total offering of $807,875,000. On May 20, 1999, the Company raised an
        additional $141,002,500, net of issuance costs, through the issuance of
        4,000,000 shares. On October 31, 2000, Boston Properties successfully
        completed an additional public offering resulting in 17,110,000 shares
        (including the underwriters' over-allotment) being sold at $39.0625 per
        share for a total offering of $668,359,000.

        Through its predecessor company founded by Mortimer B. Zuckerman and
        Edward H. Linde in 1970, the Company grew through the seventies,
        eighties, and nineties by developing and redeveloping Class A office
        properties, office/technical and industrial properties, and hotels in
        its primary markets of Greater Boston, Greater Washington, DC, and
        midtown Manhattan.

        Since the Company's initial offering in June 1997, the Company has
        acquired 47 properties adding approximately 17.7 million square feet to
        its portfolio, representing an investment of approximately $4.7 billion,
        and the Company has delivered 28 development properties adding
        approximately 4.2 million square feet to its portfolio, representing an
        investment of approximately $597.7 million. In addition, the Company is
        constructing 13 office properties for a total anticipated investment of
        approximately $1.9 billion. The Company owns or controls land where it
        can develop an additional 9.2 million square feet.
