PS Business Parks, Inc. announces the acquisition of a business park, the termination of a contract to dispose of properties in Beaverton, Oregon and a gain on sale of marketable securities.

Glendale, California – PS Business Parks, Inc. (AMEX: PSB) acquired a master-planned business park known as Orange County Business Center at a cost of approximately $46 million on June 10, 2003. The acquisition was funded with the Company’s existing cash and cash equivalents. The park consists of five low-rise multi-tenant office buildings (437,000 square feet). The Park is located in the Santa Ana suburb of Orange County and is approximately 73% occupied with 26% of the square footage expiring through December 31, 2003. The largest tenant is National Water and Power, which occupies 55,415 square feet or 13% of the Park. This acquisition expands the Company’s presence in Orange County to 1.5 million square feet and its overall presence in Southern California to approximately 3.6 million square feet. The acquisition increases the Company’s total square footage to 14.9 million rentable square feet.

Termination of contract to sell properties
The Company previously announced that it was under contract to sell five office and flex buildings and a 3.5 acre parcel of land in Beaverton, Oregon with estimated net proceeds of $34.5 million. The contract was terminated in May, 2003. The Company has not determined whether it will ultimately dispose of some or all of these properties.

Gain on sale of marketable securities
During the second quarter, the Company disposed of its marketable equity securities generating net proceeds of approximately $7.6 million and a gain on sale of the securities of approximately $2 million.
