(1) Annualized rent represents the monthly contractual rent under existing leases as of June 30, 2010 multiplied by 12. We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available power, required support space and common area.

(2) Occupancy excludes space held for redevelopment. For some of our properties, we calculate occupancy based on factors in addition to contractually leased square feet, including available power, required support space and common area.

(3) Includes approximately 33,700 rentable square feet from a leasehold interest acquisition.

(4) Net rentable square feet excludes 400,369 rentable square feet of space in a joint venture located at 2001 Sixth Avenue in Seattle, WA, which was 96.14% occupied as of June 30, 2010.
