(a)  "Total fixed charges - interest  expense"  includes  interest  expense plus
     capitalized interest, and includes $18,135,000 in interest expense incurred
     by Shurgard  Europe for the nine  months  ended  September  30,  2007,  and
     $7,737,000  for the nine months ended  September  30, 2008. As described in
     Note  3  to  our  September  30,  2008  condensed   consolidated  financial
     statements,  Shurgard  Europe was  deconsolidated  as of March 31, 2008. No
     further  interest expense for Shurgard Europe is reflected in our financial
     statements after March 31, 2008.

(b)  EBITDA  represents  earnings  prior to interest,  taxes,  depreciation  and
     amortization,  and gain on sale of an  interest in  Shurgard  Europe.  This
     supplemental  disclosure of EBITDA is included  because we believe that the
     coverage ratios computed on a pre-depreciation  basis and prior to our gain
     on sale of an interest in Shurgard  Europe 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 this 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.
