     capitalized interest, and includes $11,548,000 in interest expense incurred
     by Shurgard  Europe for the six months  ended June 30, 2007 and  $7,737,000
     for the six months ended June 30, 2008.  As described in Note 3 to our June
     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.
