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) Limited Partnership Units in BioMed Realty, L.P. (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 BioMed Realty Trust, Inc. (the "Company"), or, at the election of the Company, shares of the Company's common stock on a 1-for-1 basis.
(2) The Limited Partnership Units do not have an expiration date.
(3) These profits interest units of the Operating Partnership were granted on January 31, 2007 pursuant to the 2004 Incentive Award Plan of the Operating Partnership and the Company. The LTIP Units are subject to time-based restrictions.
(4) LTIP Units are subject to vesting 25% on each of January 1, 2008, 2009, 2010 and 2011. 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.
(5) The LTIP Units do not have an expiration date.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
