Scottsdale, Arizona (March 30, 2012) – Healthcare Trust of America, Inc. (“HTA”), a fully integrated, self-administered, self-managed real estate investment trust, is pleased to announce the closing of a new $875 million unsecured, 4 year credit facility (the “Credit Facility”). The Credit Facility consists of a $575 million revolving credit facility (the “Revolver”) and a $300 million term loan (the “Term Loan”). Proceeds will be used to fund acquisitions, the repayment of existing secured indebtedness, and for other corporate purposes.

The Credit Facility will mature in March 2016 and can be extended for one 12 month period under certain conditions. The Term Loan will be initially priced at LIBOR plus 185 bps. Based on HTA’s current investment grade ratings, the Revolver will be initially priced at LIBOR plus 190 bps, inclusive of a 35 bps facility fee. The Credit Facility will replace HTA’s existing $575 million credit facility maturing May 2014 and reduced HTA’s funded interest cost by 60 bps.

J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, and Deutsche Bank Securities Inc. served as Joint Lead Arrangers with JP Morgan Chase Bank, N.A. serving as the Administrative Agent.
