NorthWest Healthcare Properties Real Estate Investment Trust announces
acquisition in Edmonton suburb

TORONTO, June 4 /CNW/ - NorthWest Healthcare Properties Real Estate Investment Trust (the "REIT") announced today it has waived conditions and expects to close the acquisition of a new medical office building, Queen Street Place, in the Edmonton suburb of Spruce Grove, Alberta. The purchase is expected to close in the second quarter of 2010, subject to customary closing conditions.

Queen Street Place is the dominant medical building in its market. It is a newly constructed (2007), fully-leased multi-tenant medical building that is expected to provide secure income yield based on its (a) scale, at approximately 70,000 square feet of gross leasable area, and tenancy mix, which includes two large multi-practitioner clinics, a diagnostic imaging facility, a laboratory, a pharmacy (Rexall) and a mix of other medical and medically-related users such as Alberta Health Services; (b) long term leases, with an average lease term to maturity of approximately seven years; and (c) recent construction, resulting in minimal capital expenditures projected for the next ten years.

Queen Street Place will be the REIT's third asset in the Edmonton market, which is expected to provide operating efficiencies.

In addition, the investment has the potential for value enhancement since the REIT believes that the site can accommodate an additional development of approximately 10,000 square feet of gross leasable area.

The total purchase price is expected to be approximately $21 million, subject to adjustments, which represents approximately an 8% capitalization rate applied to the in-place annual net operating income from the property. NorthWest expects to assume the vendor's existing mortgage (maturing in 2013, with a current balance of approximately $11.5 million at a fixed rate of 5.9%), but it is possible that long term fixed rate refinancing for the property may be arranged in due course following closing of the acquisition. The REIT's equity investment will be funded from existing resources. The acquisition is expected to be immediately accretive.

This investment will be the REIT's first acquisition since its initial public offering ("IPO"). In the REIT's offering prospectus dated March 16, 2010 (the "Prospectus") in respect of the IPO, the REIT outlined its strategic vision and plans for external growth and further consolidation of private sector ownership of medical office buildings and healthcare real estate in Canada. The REIT believes that the Queen Street Place acquisition will further solidify its market leadership in this asset class and its position as "Canada's Healthcare Landlord".
