Brookfield Office Properties Sells 1225 Connecticut Avenue, NW in Washington, DC

NEW YORK, December 10, 2010 – Brookfield Properties Corporation “Brookfield Office Properties” (BPO: NYSE, TSX) today announced that it has sold the office building at 1225 Connecticut Avenue, NW in Washington, DC to the World Bank for $216 million.

Brookfield Office Properties acquired the eight-story property containing 240,000 rentable square feet as part of the Trizec portfolio in 2006. At that time, it was a functionally obsolete, class C building in a desirable location. Brookfield undertook a $32 million redevelopment program which completely transformed the property into an attractive, sustainable, trophy asset.

Upon completion of the redevelopment program in 2008, Brookfield leased 100% of the building’s rentable office space to the World Bank. The building was among the first redeveloped buildings in the United States to achieve LEED CS (Core & Shell) Platinum certification – the highest standard for environmental friendliness in commercial properties.

“Through our proactive leasing efforts and redevelopment capabilities we have created considerable value in this asset,” said Dennis Friedrich, president and chief executive officer of Brookfield Office Properties’ U.S. Commercial Operations. “In keeping with our capital recycling strategy, we will be proactive in seeking similar opportunities to create value within the DC market.”

Brookfield will be retained as the managing agent for the property which will ensure seamless building operations as ownership changes hands.

Brookfield Office Properties maintains a significant stake in the Greater DC office market, invested in 30 properties encompassing 7.6 million square feet across the central business district of Washington, DC and metro submarkets in Northern Virginia and Suburban Maryland.
