(1) Includes license and similar agreements that upon expiration will be automatically renewed, mostly on a month-to-month basis. Number of leases represents the leased-unit count; a lease could include multiple units.

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

(3) Annualized rent represents the monthly contractual base rent (defined as cash base rent before abatements) under existing leases as of December 31, 2012, multiplied by 12.
