BOSTON PROPERTIES ESTABLISHES ATM STOCK OFFERING PROGRAM

BOSTON, MA, April 21, 2010 – Boston Properties, Inc. (NYSE: BXP), a real estate investment trust, announced today that it has established an “at the market” stock offering program through which it may sell up to an aggregate of $400 million of its common stock. The stock would be offered through BNY Mellon Capital Markets, LLC, BofA Merrill Lynch and Morgan Stanley & Co. Incorporated, who will be acting as sales agents.

Michael LaBelle, the Company’s Chief Financial Officer, stated “With the completion of our bond issuance on April 19, 2010, we have approximately $1.8 billion of cash and our full $1.0 billion line of credit available to us. While we see no immediate need to utilize the program, the establishment of this program adds another option to our extensive array of funding alternatives providing additional efficiency and flexibility in our balance sheet management.”

The program would allow the Company to sell up to $400 million of its common stock from time to time through the sales agents for a three-year period. The sales, if any, would be made in “at the market” offerings as defined in Rule 415 of the Securities Act. In addition, the common stock may be offered and sold through privately negotiated transactions. The Company intends to use the proceeds from any offering for general corporate purposes, which may include investment opportunities and debt reduction.

The Company has filed a registration statement (including a prospectus) with the SEC for the offering of common stock described in this communication. Before you invest, you should read the prospectus in that registration statement and other documents the Company has filed with the SEC for more complete information about the Company and this offering. You may obtain these documents for free by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, the Company or the sales agents will arrange to send you the prospectus if you request it by contacting BNY Mellon Capital Markets, LLC, Attention Prospectus Department, 32 Old Slip,
