Footnotes

F1: Long-term incentive units are partnership interests in Digital Realty Trust, L.P. (the "Operating Partnership"), of which the Issuer is the general partner. These units were fully vested on the grant date. Long-term incentive units receive the same quarterly distributions as common limited partnership units of the Operating Partnership ("Common Units"). Upon the occurrence of specified events, long-term incentive units may achieve full parity with Common Units. Thereafter, vested long-term incentive units may be converted into an equal number of Common Units on a 1-for-1-basis at any time. Common Units are 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, in each case, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions or similar events.

F2: 1 for 1.
