Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The reporting person redeemed 6,346 LTIP Units of BioMed Realty, L.P. (the "Operating Partnership"), which BioMed Realty Trust, Inc.(the "Company") elected to redeem in shares of common stock of the Company. These LTIP Units achieved full parity with common units of the Operating Partnership, which may be redeemed for cash in an amount equal to the then fair value of an equal number of shares of common stock or converted into an equal number of shares of common stock, as determined by the Company.
(2) Profits interest units of the Operating Partnership.
(3) The LTIP Units are subject to time-based restrictions. Upon the occurrence of certain "triggering events," the LTIP Units can over time achieve full parity with common units of the Operating Partnership for all purposes, and therefore accrete to an economic value equivalent to one share of common stock of the Company on a one-for-one basis. If such parity is reached, vested LTIP Units convert to common units of the Operating Partnership and then may be redeemed for cash in an amount equal to the then fair value of an equal number of shares of common stock or converted into an equal number of shares of common stock, as determined by the Company.
(4) The Limited Partnership Units have no expiration date.
(5) These LTIP Units were granted on January 30, 2008 pursuant to the 2004 Incentive Award Plan of the Company and the Operating Partnership.
