Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On May 25, 2012, American Realty Capital Healthcare Trust, Inc. (the “Company”), through American Realty Capital Healthcare Trust Operating Partnership, L.P., the Company’s operating partnership, entered into a $50 million revolving credit facility (the “Credit Facility”) with KeyBank National Association. The Credit Facility contains an “accordion feature” to allow the Company, under certain circumstances, to increase the aggregate commitments under the Credit Facility to a maximum of $250 million.

The Credit Facility is a revolving line of credit with a term of 36 months, subject to the Company’s right to a 12-month extension. The Company will have the option, based upon its corporate leverage, to have the Credit Facility priced at either: (a) LIBOR, plus an applicable margin that ranges from 3.00% to 4.00%; or (b) the Base Rate, plus an applicable margin that ranges from 1.50% to 2.50%. Base Rate is defined in the Credit Facility as the greater of (i) the fluctuating annual rate of interest announced from time to time by KeyBank National Association as its “prime rate” or (ii) 0.5% above the federal funds effective rate. Once the Company reaches net worth exceeding $350 million, the applicable margin will be reduced by 0.35%.

The Credit Facility provides for monthly interest payments with all principal outstanding being due on the maturity date in May 2015. The Credit Facility may be prepaid at any time, in whole or in part, without premium or penalty. In the event of a default, the lender has the right to terminate its obligations under the Credit Facility and to accelerate the payment on any unpaid principal amount of all outstanding loans. The Company has guaranteed the obligations under the Credit Facility.

The description of the Credit Facility in this Current Report on Form 8-K is a summary and is qualified in its entirety by the terms of the Credit Facility.
