NEW YORK, December 9, 2011 – Brookfield Office Properties Inc. (BPO: NYSE, TSX) today announced that it has acquired, together with an investment consortium, 1801 California Street in Denver, CO from PSEG Energy Holdings for $215 million. Brookfield Office Properties’ economic interest in this asset is approximately $110 million, or 51%, and it will manage the property on behalf of the consortium. The company completed the transaction using its available cash resources and through an acquisition facility.

Located in Denver’s central business district, 1801 California Street, formerly known as Qwest Tower, is a 54-story, Class A office building containing 1.4 million rentable square feet and more than 1,500 parking spaces. It is the second tallest building in Denver, after the Brookfield-owned Republic Plaza. The building is located across the street from the 18th & California light rail and two bus stations are within two blocks.

“The Denver market has demonstrated strong fundamentals with positive absorption and job growth over the past 18 months. 1801 California Street fits our strategy of owning premier assets in the best-located areas within our operating markets,” said Dennis Friedrich, president and global chief investment officer of Brookfield Office Properties. “This acquisition generates another opportunity where we can add value through pro-active management and continues our capital recycling program, through which we have sold $1 billion of gross assets over the past 12 months, redeploying $350 million of capital into more accretive investments.”

Brookfield is planning to undertake a capital program to reposition the property as a market-leading asset. The building is currently 100% leased; 80% of existing leases are set to expire by July 2012. The top tenants include CenturyLink/Qwest, Patton Boggs and MWH Americas Inc.
