        <footnote id="F1">Represents long-term incentive units in Digital Realty Trust, L.P. a Maryland Limited Partnership (the &quot;Operating

Partnership&quot;), of which the Issuer is the general partner.  Long-term incentive units will initially not have full parity with

common limited partnership units of the Operating Partnership; however, upon the occurrence of specified events, long-term

incentive units may over time achieve full parity with common

units in the Operating Partnership for all purposes, and

thereafter may be converted into an equal number of common units

of the Operating Partnership on a one for one basis at any time.  Common limited partnership units of the Operating

Partnership are redeemable commencing fourteen months from the consummation of the Issuer's initial public offering 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,

an equal number of shares of the Issuer's common stock.</footnote>
