ITEM 5.  Other Events

PS Business Parks,  Inc.,  through its  consolidated  partnership  (collectively
referred  to as the  "Company"),  acquired  a  business  park  consisting  of 17
buildings  known as "Metro  Park North" on  December  27,  2001 at an  aggregate
purchase  price of  approximately  $127.3 million  (including  closing costs and
deferred  maintenance).  The park was acquired  through the  acquisition of five
limited  liability  companies  controlled  by one  seller.  The  Company  is not
affiliated with the seller and the purchase price was established  through arm's
length negotiations. The acquisition was funded with the Company's existing cash
balances, borrowings of $40 million from its unsecured line of credit with Wells
Fargo Bank and borrowings from an affiliate of $35 million.

The following  table  provides  certain  information  concerning  the facilities
acquired:
