Item 1.01. Entry into a Material Definitive Agreement.

On August 5, 2012, Chesapeake Lodging Trust (the “Trust”) entered into a definitive agreement to acquire a full-service hotel located in Chicago, Illinois for $126.0 million from an unaffiliated third party. The Trust intends to fund the acquisition with available cash and cash equivalents and by borrowing under its revolving credit facility. The Trust expects the acquisition to close in the third quarter 2012, subject to customary closing conditions, but can give no assurance that the acquisition will be consummated during that time period, or at all.

Certain statements and assumptions in this filing contain or are based upon “forward-looking” information and are being made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to risks and uncertainties. When the Trust uses the words “will likely result,” “may,” “anticipate,” “estimate,” “should,” “expect,” “believe,” “intend,” or similar expressions, the Trust intends to identify forward-looking statements. Such forward-looking statements include, but are not limited to, the Trust’s expectations as to the mix of consideration to be paid and time for completing, if at all, the acquisition described. Such statements are subject to numerous assumptions and uncertainties, many of which are outside Trust’s control. The Trust undertakes no obligation to publicly release the result of any revisions to these forward-looking statements that may be made to reflect any future events or circumstances, except as required by law.
