Brookfield Properties Enters into Joint Venture to Acquire 50% Interest in 100 Bishopsgate in City of London

Partnership Signifies Company's Expansion to Property Interests Outside of North America

NEW YORK, Mar 31, 2010 (BUSINESS WIRE) - Brookfield Properties Corporation (NYSE: BPO; TSX: BPO) announced today that it has entered into a joint venture with Great Portland Estates (GPE) - a United Kingdom-based REIT - to acquire a 50% ownership interest in the 100 Bishopsgate partnership ("JV") for $64 million (£43 million). The partnership is a 50:50 joint venture with all income, expenditures and capital costs to be shared equally.

The JV holds all of GPE's Bishopsgate holdings in the City of London, forming the two-acre Bishopsgate development site ("the Site"). The Site, ideally located in the heart of the City, close to the Liverpool Street Station, currently houses 252,000 rentable square feet of existing buildings yielding approximately $11 million (£7.4 million) of net operating income from in-place leases.

Planning consent was achieved by GPE in May 2008 for a total of 820,000 square feet of office, ancillary retail, public library and new Livery Hall space in two buildings, including a forty-story office tower. It is anticipated that the JV will submit a revised planning application in 2010 which may include revisions to the consented scheme, positioning 100 Bishopsgate for development thereafter.

"With its prominent address and proximity to Liverpool Street Station, GPE has assembled one of the most dynamic sites in the heart of the City of London," said Ric Clark, chief executive officer of Brookfield Properties. "Combining GPE's local expertise and reputation with Brookfield's construction and development skills and global tenant relationships, makes this an exciting and compelling opportunity for Brookfield Properties."

We are delighted to be working together with Brookfield on what promises to be a building of the highest quality in a prime City location," said Toby Courtauld, chief executive of GPE. "Bringing together Brookfield's undoubted skills in delivering buildings of this kind with our local expertise provides a powerful combination."

Under terms of the agreement, Brookfield will manage construction and development, including the initial lease-up of the new properties, which will be designed and built to the same best-in-class standards as the company's recently developed office buildings in North America.

Brookfield Properties has developed over three million square feet of new premier office properties in North America in the past decade, including 300 Madison Avenue in New York, 77 K Street in Washington, DC, Bay Adelaide Centre in Toronto and Bankers Court in Calgary. The new interest in 100 Bishopsgate adds to the company's existing 15-million-square-foot North American development pipeline.
