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 7,000 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. 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.
(2) Represents gift of shares to charity.
(3) Limited Partnership Units in the Operating Partnership. Limited Partnership Units are redeemable for cash based upon the fair market value of an equivalent number of shares of common stock of the Company, or, at the election of the Company, shares of the Company's common stock on a 1-for-1 basis.
(4) The Limited Partnership Units have no expiration date.
(5) Profits interest units of the Operating Partnership. The LTIP Units are subject to time-based restrictions.
(6) The LTIP Units do not have an expiration date.
(7) An irrevocable trust of which a family member of the reporting person is a trustee and of which one of the reporting person's adult children is the sole beneficiary.
