BioMed Realty Trust Leases 79,667 Square Feet of Additional Space at King of Prussia to Centocor, Inc.

Also Acquires Eighth Property in San Diego


SAN DIEGO, April 26, 2005 (PRIMEZONE) -- BioMed Realty Trust, Inc. (NYSE:BMR) today announced it has leased an additional 79,667 rentable square feet of space at its King of Prussia property located in Radnor, Pennsylvania to Centocor, Inc., a subsidiary of Johnson & Johnson (NYSE:JNJ), under a five-year, triple-net lease commencing on May 1, 2005. With the new lease, Centocor, a strong Tier I tenant, will represent approximately 12.0% of BioMed's total annualized base rent, up from 10.7% at the end of 2004.

The new lease replaces the existing portion of the master lease with an affiliate of The Rubenstein Company, the original seller of the property, with respect to this space. Annualized base rent of approximately $1.3 million and certain tenant reimbursements received under the new lease will correspondingly reduce the rent received under the master lease.

BioMed also announced it has acquired its eighth property in San Diego, located on Nancy Ridge Drive in the Sorrento Mesa submarket. The Nancy Ridge Drive property contains approximately 42,100 rentable square feet of laboratory and office space that is 100% leased to two tenants. The total purchase price of approximately $12.8 million was funded with cash and the assumption of approximately $7.0 million of debt.

The acquisition increases the company's real estate portfolio to 23 properties, representing 45 buildings with approximately 3.1 million rentable square feet.

"Leasing the additional space, which will be fully improved by Centocor, further allows Centocor to expand its research activities at the King of Prussia property. We also are pleased to have further expanded in the important San Diego market through the acquisition of the Nancy Ridge property," said Alan D. Gold, president and chief executive officer of BioMed Realty Trust.
