                              SECOND QUARTER 2000

                               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 office properties in the
United States, concentrated in the Northeast Corridor from Virginia to Greater
Boston and in Greater 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.

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, R&D 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 16.0 million square feet to its portfolio,
representing an investment of approximately $3.9 billion, and the Company has
delivered 17 development properties adding approximately 2.5 million square feet
to its portfolio, representing an investment of approximately $366 million. In
addition, the Company is developing thirteen Class A Office Buildings for a
total anticipated investment of approximately $1.1 billion. The Company owns or
controls land where it can develop an additional 10.3 million square feet.
