CarrAmerica Agrees To Be Acquired By The Blackstone Group

Washington D.C. – March 6, 2006 – CarrAmerica Realty Corporation (NYSE:CRE) today announced that it has signed a definitive merger agreement to be acquired by an affiliate of The Blackstone Group in a transaction valued at approximately $5.6 billion.
Under the terms of the agreement, Blackstone will acquire all of the outstanding common stock of CarrAmerica for $44.75 per share in cash. The purchase price per share represents an 18.4% premium over CarrAmerica’s closing stock price on February 16, 2006, the date prior to published reports regarding a potential acquisition of CarrAmerica. CarrAmerica is permitted to pay its regular quarterly dividend for the quarter ending March 31, 2006, but will not pay any dividends on its common stock thereafter.
CarrAmerica’s Board of Directors has unanimously approved the merger agreement and has recommended the approval of the transaction by CarrAmerica’s common stockholders. Completion of the transaction, which is currently expected to occur in the second quarter of 2006, is contingent upon customary closing conditions and the approval of CarrAmerica’s stockholders, who will be asked to vote on the proposed transaction at a special meeting that will be held on a date to be announced. The transaction is not contingent on receipt of financing by Blackstone.
Blackstone has agreed that, as promptly as practicable after the completion of the merger, it will liquidate the surviving corporation in the merger. In the liquidation, each holder of a share of the 7.50% Series E Cumulative Redeemable Preferred Stock will receive $25.00 per share in cash plus any then accrued but unpaid dividends.
The common limited partnership interests in two of CarrAmerica’s operating partnerships will be acquired for $44.75 per unit in cash. Qualified holders of common limited partnership interests will be given the option (in lieu of cash) to elect to receive preferred units of limited partnership interest in the partnerships following the merger.

“CarrAmerica has dedicated the last 13 years to building an exceptional public commercial real estate company on behalf of its stockholders,” said CarrAmerica Chairman and CEO, Thomas A. Carr. Mr. Carr continued, “Over the past few years, CarrAmerica has emerged as a leader in its markets with growing occupancy, a markedly upgraded portfolio of office properties and a very dedicated and talented organization. And yet, with our most aggressive performance assumptions, we don’t believe we could match the value being offered to our shareholders today by this offer. We believe this transaction will allow us to fulfill our mission with our stockholders and also create new opportunities for growth and success for CarrAmerica as we go forward.”
Jonathan D. Gray, Senior Managing Director of The Blackstone Group, said, “We feel extremely fortunate to have the opportunity to acquire CarrAmerica. The Company represents one of the premier collections of people and properties in the country and will provide us with a valuable platform for future investments in the office sector.”

Acquisition financing is being provided to Blackstone by Deutsche Bank, Bank of America and Citigroup. Hogan & Hartson L.L.P. acted as legal advisor to CarrAmerica.
