                               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 29 development properties adding approximately 4.3 million square feet
to its portfolio, representing an investment of approximately $568.5 million. In
addition, the Company is constructing 12 office properties for a total
anticipated investment of approximately $1.8 billion. The Company owns or
controls land where it can develop an additional 9.7 million square feet.
