Item 8.01 Other Events.

On February 1, 2013, Chesapeake Lodging Trust (the “Trust”) and Chesapeake Lodging, L.P. entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC, Deutsche Bank Securities Inc., Wells Fargo Securities, LLC and RBC Capital Markets, LLC, as representatives of the several underwriters named in Schedule 1 thereto (collectively, the “Underwriters”), in connection with the public offering of 7,250,000 of the Trust’s common shares of beneficial interest, par value $0.01 per share (the “Common Shares”). Pursuant to the Underwriting Agreement, the Trust granted the Underwriters a 30-day option to purchase up to an additional 1,087,500 Common Shares, which the Underwriters have exercised in full. The closing of the offering is expected to occur on or about February 6, 2013. The Trust estimates that the net proceeds from the offering, after deducting underwriting discounts and estimated offering expenses payable by the Trust, will be approximately $165.8 million, taking into account the Underwriters’ full exercise of their option to purchase additional shares. Robert W. Baird & Co. Incorporated, KeyBanc Capital Markets Inc. and JMP Securities LLC served as co-managers of the offering.

A copy of the Underwriting Agreement is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference. The summary set forth above is qualified in its entirety by reference to Exhibit 1.1.
