Item 1.01. Entry into a Material Definitive Agreement.

New Term Loan Agreement

On September 28, 2015, we entered into a new term loan agreement with Wells Fargo Bank, National Association, as administrative agent and lender, and a syndicate of other lenders, pursuant to which we obtained a $200 million term loan facility with a maturity date of September 28, 2022. The new term loan bears interest at a rate of LIBOR plus 180 basis points, which interest rate is subject to adjustment based on changes to our credit ratings. Obligations under the term loan agreement are unsecured. The new term loan agreement includes a feature under which maximum borrowings may be increased to up to $400 million in certain circumstances.

We used the net proceeds of the new term loan to repay $197.2 million of outstanding borrowings under our pre-existing revolving credit facility.

Principal payments of the new term loan are not required prior to maturity. Voluntary prepayments of the new term loan may be made at any time. We are required to pay a 2% prepayment premium on amounts prepaid during the first year of the new term loan and a 1% prepayment premium on amounts prepaid during the second year, and prepayments thereafter may be made without a prepayment premium.

The new term loan agreement contains a number of covenants that restrict our ability to incur debt in excess of calculated amounts, restrict our ability to make distributions under certain circumstances and generally require us to maintain certain financial ratios. The new term loan agreement provides for acceleration of payment of all amounts due thereunder upon the occurrence and continuation of certain events of default, such as a change of control of us, which includes Reit Management & Research LLC ceasing to act as our business and property manager.

Amendments to Pre-Existing Revolving Credit Facility and Term Loan Agreements

Also on September 28, 2015, we amended the agreements governing our pre-existing revolving credit and term loan facilities, each with Wells Fargo Bank, National Association, as administrative agent and a lender, and a syndicate of other lenders. Pursuant to the amendment to our pre-existing revolving credit facility agreement, the maximum amount of our revolving credit facility increased from $750 million to $1 billion. Our pre-existing revolving credit facility continues to include a feature under which maximum borrowings may be increased to up to $1.5 billion in certain circumstances. In addition, the amendments to the agreements governing our pre-existing revolving credit and term loan facilities modify certain covenants and defined terms.

Other Considerations

Wells Fargo Bank, National Association and the other lenders party to the new term loan agreement and our pre-existing revolving credit and term loan agreements, as well as their affiliates, have engaged in, and may in the future engage in, investment banking, commercial banking, advisory and other commercial dealings in the ordinary course of business with us. They have received, and may in the future receive, customary fees and commissions for these engagements.

The foregoing descriptions of the new term loan agreement, and of the agreements governing our pre-existing revolving credit and term loan facilities, as amended, are not complete and are subject to and qualified in their entirety by reference to: (1) the new term loan agreement, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K; (2) our pre-existing credit facility agreement, a copy of which is attached as Exhibit 10.1 to our Current Report on Form 8-K dated June 27, 2011, and the amendments thereto, copies of which are attached as Exhibit 10.1 to our Current Report on Form 8-K dated September 4, 2013, Exhibit 10.3 to our Quarterly Report on Form 10-Q for the quarter ended June 30, 2014 and Exhibit 10.2 to this Current Report

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

The information contained in Item 1.01 of this Current Report on Form 8-K is incorporated into this Item 2.03 by reference.

Item 7.01. Regulation FD Disclosure.

On September 29, 2015, we issued a press release announcing the new term loan facility and the increase in the amount of our pre-existing revolving credit facility described in Item 1.01 of this Current Report on Form 8-K. A copy of that press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
