Scottsdale, Arizona (December 28, 2010) – Healthcare Trust of America, Inc. (“HTA”), a self-managed, non-traded, real estate investment trust, announced the completed acquisition of a medical office building in Santa Fe, New Mexico (the “St. Vincent 1640 MOB”) for approximately $6,232,000. HTA previously announced the completed purchase of the St. Vincent 440 MOB as part of the “Santa Fe Portfolio”. These two medical office buildings were acquired in off-market transactions for $15,790,000 and are adjacent to the 268-bed CHRISTUS St. Vincent Hospital.

The St. Vincent 1640 MOB is an approximately 20,000 square foot medical office building that is 100% leased to CHRISTUS St. Vincent Regional Medical Center (“CHRISTUS St. Vincent Hospital”) with a remaining lease term of ten years. The building houses diagnostic imaging and related services on an outpatient basis. Combined, the Santa Fe Portfolio represents approximately 54,000 square feet of Class A medical office space that is 100% leased on a long-term basis.

CHRISTUS St. Vincent Hospital was founded in 1865 by the Sisters of Charity and is the largest private employer in Santa Fe. CHRISTUS St. Vincent Hospital is a community-based, private, not-for-profit hospital serving more than 300,000 people in seven counties in northern New Mexico. CHRISTUS St. Vincent Hospital is designated as a “sole community provider” by the Centers for Medicare and Medicaid Services and accredited by the Joint Commission on Accreditation of Healthcare Organizations.

“The opportunity to acquire the Santa Fe Portfolio before it went to market demonstrates our continued leadership as active buyers and owners of medical office buildings,” stated Mark D. Engstrom, Executive Vice President of Acquisitions for HTA. “These stabilized long-term leased assets, with investment grade credit enhances our already strong portfolio fundamentals.”

Since January 1, 2010, HTA has acquired approximately $715 million in medical office and healthcare related assets based on acquisition price, including 3.09 million square feet of gross leasable area in 2010, which is 98% leased with an average remaining lease term of 9 years.
