WESTPAC OFFICE TRUST MERGER COURT APPROVES MIRVAC’S ACQUSITION OF WESTPAC OFFICE TRUST

Mirvac Group ("Mirvac”) [ASX: MGR] advises that Westpac Funds Management Limited ("WFML"), as responsible entity of the Westpac Office Trust ("WOT"), has obtained orders from the New South Wales Supreme Court that WFML would be justified in implementing the:

• resolutions approved by WOT unitholders on 21 July 2010; and

• trust scheme by which Mirvac will acquire all of the units in WOT (the “Scheme”).

A copy of the orders will be lodged with ASIC by WFML.

Mirvac’s Managing Director, Nick Collishaw, said “We are very pleased that implementation of the Scheme can now proceed following the overwhelming support from WOT unitholders who voted on 21 July 2010 and the orders from the Supreme Court today."

“Following implementation of the Scheme, the $1.1 billion WOT portfolio will be a complementary fit with Mirvac’s quality portfolio of Australian investment grade assets. The combined entity will provide a well leased, quality Australian property investment vehicle, capable of generating predicable earnings growth well into the future.”

The timetable for the steps to implement the Scheme remains unchanged from that included in the WOT explanatory memorandum dated 16 June 2010 ("Explanatory Memorandum"). The key dates are provided in Appendix A .
