FOR IMMEDIATE RELEASE

CommonWealth REIT Sets Conditional Record Date

Newton, MA (February 10, 2014): CommonWealth REIT (NYSE: CWH) today announced that, in an effort to bring the prolonged disruption and cost to shareholders caused by Related Fund Management LLC and Corvex Management LP (“Related/Corvex”) to an end, CWH has set February 18, 2014 as the record date for shareholders entitled to participate in the written consent proposed by Related/Corvex to remove the entire CWH Board of Trustees, including two recently added Independent Trustees, without cause.  This record date is conditioned upon Related/Corvex making a record date demand on or before February 16, 2014, as required by the Arbitration Panel in its November 18, 2013 order.

Adam Portnoy, Managing Trustee and President of CWH made the following statement regarding today’s announcement:

“Despite their professed desire to proceed expeditiously, it appears that Related/Corvex will delay until the last possible moment to ask for a record date in their attempt to take control of CWH for their own benefit and without paying shareholders.  Unlike Related/Corvex, the Board believes that it is in the best interests of shareholders to move ahead in order to limit the damage to CWH and its shareholders which may be caused by the disruptive activities of Related/Corvex.  We look forward to our continued engagement with shareholders over the coming weeks.  We will also continue to vigorously oppose Related/Corvex’s disruptive and self-serving actions, and we are confident shareholders will support the Board’s continued efforts to create value for all shareholders.”

CommonWealth REIT is a real estate investment trust that primarily owns office properties located in central business district or urban locations throughout the United States.  CWH is headquartered in Newton, MA.
