On October 25, 2012, Chesapeake Lodging, L.P., the operating partnership and a wholly owned subsidiary of Chesapeake Lodging Trust (the “Trust”), amended the credit agreement by which it has obtained a senior secured revolving credit facility with a lending syndicate led by Wells Fargo Bank, N.A., as administrative agent, JPMorgan Chase Bank, N.A., as syndication agent, and Deutsche Bank Securities Inc., as documentation agent. The Trust and certain of its indirect subsidiaries serve as guarantors of borrowings under the credit facility. The amended credit agreement increases the maximum amounts the Trust may borrow from $200.0 million to $250.0 million, and also provides for the possibility of further increases, up to a maximum of $375.0 million, in accordance with the terms of the amended credit agreement. The actual amount that the Trust can borrow under the senior secured revolving credit facility continues to be based on the value of the Trust’s hotels included in the borrowing base, as defined in the amended credit agreement. A copy of the Trust’s press release announcing this transaction is filed as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

The initial term of the amended credit agreement will now expire in April 2016, subject to extension for another year at the Trust’s option subject to satisfaction of customary conditions. Amounts borrowed under the amended credit agreement will bear interest at spreads over LIBOR that will be determined based on the Trust’s consolidated leverage ratio as of the end of its most recent fiscal quarter, as shown below:

The applicable margin will reset 10 business days after each delivery of a compliance certificate relating to our quarterly or year-end financial results, as applicable. For the period from October 25, 2012 until the next reset date, the applicable margin will be 1.75%.

Other than as described above, the amended credit agreement effected no material changes to the financial covenants, including leverage and coverage ratios and minimum tangible net worth requirement, or other business terms of the credit facility, as compared to those previously in effect.

The foregoing description of the amended credit agreement is qualified in its entirety by the full terms and conditions of the amended credit agreement which will be filed with the Securities and Exchange Commission as an exhibit to a subsequent report of the Trust.
