Brookfield Office Properties Secures PwC as Major City Square Tenant

PERTH, Australia, 23 February 2011 – Brookfield Properties Corporation (“Brookfield Office Properties”) (NYSE, TSX: BPO) today announced it has signed a new ten year lease agreement with a leading professional services firm. PwC will occupy 8,500 square metres (91,494 square feet) or 11.3 per cent of Brookfield Office Properties’ newest office building, City Square in Perth. This new lease takes the office tower to 93.3% pre-leased with the balance of space under negotiation.

"We are delighted to welcome PwC to City Square, which is fast establishing itself as Western Australia’s premier business address," said Kurt Wilkinson, Chief Operating Officer of Brookfield Office Properties’ Australian Commercial Operations. "City Square is the largest premium-grade office development currently under construction in Australia. It has been designed to meet the demand from large, internationally-recognised businesses, for world-class office space in Perth."

John O'Connor, PwC's Perth Managing Partner, said the move to City Square reflects the firm’s commitment to, and belief in, the continued growth of Western Australia as a business centre. “We view Western Australia as a significant growth market for PwC and our new City Square premises will position us to continue our expansion plans in Perth.

“City Square is an exciting new development which places PwC in the hub of the CBD. Its design allows for large, interconnected work areas that meet the operational and cultural requirements of our firm. I am confident our staff will enjoy the environment of the new building which will offer an outstanding range of services and amenities,” Mr O’Connor concluded.

The 75,000 square metre (807,300 square feet) City Square project, which includes a premium-grade office tower and a unique heritage retail precinct, is being built by Brookfield Multiplex and is targeting completion at the end of 2011. BHP Billiton is the tower’s anchor tenant, occupying 61,500 square metres (661,980 square feet), or 82 per cent of the building.

City Square’s office tower has a side-core design providing views south over the Swan River and large floor plates to create open workspaces. The building is targeting a five-star Green Star Design rating and will feature 330 car park bays for tenants.
