NEW YORK, NY--(Marketwire - Oct 31, 2011) - Brookfield Office Properties Inc. (NYSE: [ BPO ]) (TSX: [ BPO ]) announced today that it has executed a lease renewal with Bank of America/Merrill Lynch for 767,000 square feet of office space at the World Financial Center in Lower Manhattan. It is the second-largest office lease signed in Lower Manhattan this year following Conde Nast's commitment to occupy one million square feet at One World Trade Center.

Brookfield has executed approximately 1.4 million square feet of leasing at the World Financial Center thus far in 2011.

"Renewing Bank of America/Merrill Lynch for a sizable amount of space at the World Financial Center was an important objective within our New York City portfolio," said Mitch Rudin, president and chief executive officer of Brookfield Office Properties' U.S. Commercial Operations division. "Leasing activity in Lower Manhattan thus far in 2011 has eclipsed that of all of 2010, fueled by existing financial services tenants like BofA/Merrill, as well as historical Midtown users looking to reposition their firms by leveraging Downtown's dynamic changes in retail, transit and parkland."

Bank of America/Merrill Lynch is retaining space in both Four World Financial Center and Two World Financial Center.

Brookfield has agreed to purchase BofA/Merrill's 49% interest in Four World Financial Center and now owns 100% of the 1.9-million-square-foot property. The purchase price of the 49% stake was $264 million.

Brookfield Office Properties is the largest office landlord in the Lower Manhattan market. In addition to the 8-million-square-foot World Financial Center, Brookfield also owns and operates One Liberty Plaza and One New York Plaza.
