PS Business Parks, Inc. announces three separate real estate acquisitions totaling approximately 3.6 million square feet.

Glendale, California — PS Business Parks, Inc. (AMEX:PSB), has acquired approximately 3.6 million square feet of multi-tenant properties in three separate transactions, all of which closed in December, 2003. Two acquisitions took place in existing core markets, and the third took place in a new core market for the Company. The total cost of the acquisitions was approximately $242 million.

On December 19, 2003, the Company acquired four flex multi-tenant buildings in the Metro/Black Canyon submarket of Phoenix, Arizona, totaling approximately 110,000 square feet for $9.5 million. The buildings are 83% occupied. This acquisition increases the Company’s presence in the Phoenix market to 669,000 square feet. This business park is adjacent to Corporate Park, a 200,000 square foot business park which the Company has owned and operated since 1999.

On December 24, 2003, PSB purchased two multi-tenant office buildings in the Central Orange County submarket of Orange, California, totaling approximately 107,000 square feet for $15.5 million. The buildings are 84% occupied. The acquisition increased the Company’s presence in Orange County to 1.6 million square feet and in the Southern California market to 3.7 million square feet.

On December 30, 2003, PSB entered a new core market by purchasing Miami International Commerce Center (MICC), a well-established 53 building portfolio totaling approximately 3,350,000 square feet adjacent to the Miami International Airport. The portfolio consists of approximately 3.3 million square feet of multi-tenant industrial and flex space and approximately 60,000 square feet of retail space. The facility was acquired at a cost of approximately $217 million including transaction costs and an estimate to bring the park to the Company’s operating standards. The Company will undertake several improvements to the park over the next several quarters.

The total cost of the acquisitions was approximately $242 million. The Company financed the transactions using $47 million of existing cash, $95 million from its line of credit, and $100 million of short-term borrowings. The Company expects to ultimately finance these transactions with permanent capital.

A conference call is scheduled for Thursday, January 8, 2004 at 10:00 A.M. (PST) to discuss these three acquisitions. The toll free number is 1-800-399-4409; the conference ID is 4776387. A replay of the conference call will be available through January 15, 2004 at 1-800-642-1687.
