Wells REIT Changes Name to Piedmont Office Realty Trust

New Website: www.piedmontreit.com

NORCROSS, Ga. (August 10, 2007) — Wells Real Estate Investment Trust Inc., which became a self-managed office REIT this spring, announced today its new name: Piedmont Office Realty Trust, Inc. The REIT, one of the largest office REIT’s in the country, was incorporated in 1997 but utilized external advisors to acquire and manage its properties until it internalized its management team in April 2007. Piedmont currently owns approximately $5 billion in assets, including more than 80 buildings nationwide, specializing in multi-tenant Class-A office buildings.

“The name change is a natural progression in our strategy of differentiating ourselves as a unique, self-managed REIT,” said Donald A. Miller, CFA, Piedmont’s president and CEO. The company is also launching a new website, www.piedmontreit.com which contains a gallery of its properties.

Piedmont Office Realty Trust currently owns 82 buildings located primarily in the ten largest U. S. office markets (based upon rentable square feet) totaling more than 21 million square feet in 23 states (including Washington, D.C.) Properties include the corporate headquarters of such organizations as AT&T Wireless/Cingular, U.S. Bancorp, NASA and Nestle USA. Across the portfolio, Piedmont properties are approximately 94 percent leased, and 91% of its tenants (based upon gross rent revenues) are rated investment-grade according to Standard & Poor’s, are subsidiaries of investment-grade entities, are governmental agencies, or are nationally recognized corporations or professional service firms.
