Explanation of Responses:

1. Edward Sham converted 20,000 Class C Profits Interest Units ("Class C Units") into common limited partnership units ("Common Units") of Digital Realty Trust, L.P., a Maryland Limited Partnership (the "Issuer"), and subsequently redeemed the 20,000 Common Units for 20,000 shares of the common stock of Digital Realty Trust, Inc. (the "General Partner"), all in accordance with the requirements of the Limited Partnership Agreement of the Issuer.

2. Class C Units are membership interests in the Issuer of which the General Partner is the general partner. Class C Units that have satisfied the performance condition and achieved full parity with Common Units 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 General Partner's common stock, or, at the election of the General Partner, for an equal number of shares of the General Partner's common stock. The Class C Units have achieved full parity with Common Units.

7. Long-term incentive units are profits interest units in the Issuer. Vested profits interest units may be converted into an equal number of Common Units in the Issuer on a one-for-one basis at any time. Common Units are redeemable for cash based on the fair market value of an equivalent number of shares of the General Partner's common stock, or, at the election of the General Partner, for an equal number of shares of the General Partner's common stock, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions or similar events.
