Thomas Properties Group Responds to Stockholder Letter

Thomas Properties Group, Inc. (NASDAQ: TPGI) announced that its Board of Directors reviewed the unsolicited indication of interest by a group of stockholders led by the Weisman Group requesting that TPGI discuss with them a strategic review of its properties, ways to maximize property management efficiency, and the merits of a going-private transaction.

James A. Thomas, Chairman, President and Chief Executive Officer of TPGI, responded today, "Our Board appreciates the interest of the Weisman Group in our company, as it does all of its stockholders. At this time, the Board of Directors is focused on the strategic plan being implemented by management and does not believe that it is the right time to entertain discussions of the nature suggested in the Weisman Group’s letter. The Board of Directors is supportive of the actions that the company has taken and is taking to deleverage our portfolio and replace near term loan maturities to better position the company for the future. We believe these and other strategic activities will contribute to unlocking the inherent value of the company and benefit all stockholders for the long term.”
