(1)	James Trout converted 4,000 long-term incentive units into common limited partnership units ("Common Units") of Digital Realty Trust, L.P., a Maryland Limited Partnership (the "Operating Partnership"), and subsequently redeemed the 4,000 Common Units, all in accordance with the requirements of the Limited Partnership Agreement. Common Units are redeemable for cash based on the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. (the "Issuer's") common stock, or at the election of the Issuer, an equal number of shares of the Issuer's common stock . Issuer elected to redeem Mr. Trout's Common Units with shares of its common stock.
(2)	The securities owned by Mr. Trout are long-term incentive units which are profits interest units in the Operating Partnership. Upon vesting, profits interest units may initially not have full parity with Common Units with respect to liquidating distributions; however, upon the occurrence of specified events, profits interest units may achieve full parity with Common Units for all purposes. (Footnote continued)
(3)	Thereafter vested profits interest units may be converted into an equal number of Common Units in the Operating Partnership 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, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions or similar events.
