(a)  "Total fixed charges - interest  expense"  includes  interest  expense plus
     capitalized  interest,  and includes  $7,737,000 and $5,572,000 in interest
     expense  incurred by Shurgard  Europe for the three  months ended March 31,
     2008 and 2007,  respectively.  As described in Note 3 to our March 31, 2008
     financial  statements,  Shurgard Europe was  deconsolidated as of March 31,
     2008. No further  interest expense for Shurgard Europe will be reflected in
     our financial statements after March 31, 2008.

(b)  EBITDA  represents  earnings  prior  to  interest,   taxes,   depreciation,
     amortization,  gains on sale of real  estate  assets  and the impact of the
     application of EITF Topic D-42. This  supplemental  disclosure of EBITDA is
     included  because  we  believe  that  the  coverage  ratios  computed  on a
     pre-depreciation  basis  are a  meaningful  measure  of our  liquidity  and
     financial  analysts and other members of the investment  community consider
     coverage  ratios for real estate  companies  on a  pre-depreciation  basis.
     EBITDA should not be used as an alternative  to net income,  cash flow from
     operations,  or our ratio of Earnings to Fixed  Charges in  evaluating  our
     liquidity or operating results.
