        <footnote id="F1">Class C Profits Interest Units (&quot;Class C Units&quot;) are membership interests in Digital Realty Trust, L.P., a Maryland limited partnership of which the issuer is the general partner (the &quot;Operating Partnership&quot;). Class C Units that have satisfied the performance condition and achieved full parity with common limited partnership units of the Operating Partnership (&quot;Common Units&quot;) receive the same quarterly distributions as Common Units, and may be converted into an equal number of Common Units on a one-for-one basis at any time. Common Units will be redeemable for cash based on the fair market value of an equivalent number of shares of the issuer's common stock, or, at the election of the issuer, for an equal number of shares of the issuer's common stock. The Class C Units, initially granted on May 2, 2007, have achieved full parity with Common Units.</footnote>
        <footnote id="F2">Reflects number of Class C Units that satisfied the specified performance condition and were eligible to vest as of May 1, 2010. The performance condition was satisfied in full and maximum dollar value available under the award was achieved. The remaining Class C Units granted to the reporting person on May 2, 2007 were in excess of the maximum dollar value eligible to vest and therefore were automatically cancelled and forfeited on May 1, 2010. More information about these Class C Units can be found in the Proxy Statement filed by the issuer on February 26, 2010.</footnote>
