Unsecured Revolving Credit Facility

On January 23, 2015, we entered into an unsecured revolving credit agreement, which is referred to herein as the “unsecured revolving credit facility,” with Bank of America, Merrill Lynch, Goldman Sachs and the other lenders party thereto. Merrill Lynch acted as joint lead arranger; Bank of America acted as administrative agent; and Goldman Sachs acted as syndication agent and joint lead arranger.

Concurrently with entering into the unsecured revolving credit facility, on January 23, 2015, we terminated our secured revolving and term credit facility and wrote off $1.3 million of deferred financing costs. In connection with the termination of the secured revolving and term credit facility, all of the guarantors thereunder were released from their guaranty obligations, all liens created thereby were terminated, and all collateral pledged thereunder was released.

The unsecured revolving credit facility is comprised of a revolving credit facility in the maximum original principal amount of $800.0 million. The unsecured revolving credit facility contains an accordion feature that would allow us to increase the maximum aggregate principal amount to $1.25 billion under specified circumstances. As of March 31, 2015, the unsecured revolving credit facility had an outstanding balance of $165.0 million.

Amounts outstanding under the unsecured revolving credit facility bears interest at a floating rate equal to, at our election, (x) a Eurodollar rate, plus a spread that range from 0.875% to 1.600% depending upon our leverage ratio and credit rating; or (y) a base rate, plus a spread that range from 0.000% to 0.600% depending upon our leverage ratio and credit rating. In addition, the unsecured revolving credit facility permits us to borrow at competitive bid rates determined in accordance with the procedures described in the unsecured revolving credit facility. We paid certain customary fees and expense reimbursements.

The unsecured revolving credit facility initial maturity is January 2019. We have the option to extend the initial term for up to two additional 6-month periods, subject to certain conditions, including the payment of an extension fee equal to 0.075% of the then outstanding commitments under the unsecured revolving credit facility.

The unsecured revolving credit facility includes the following financial covenants: (i) maximum leverage ratio of total indebtedness to total asset value of the loan parties and their consolidated subsidiaries will not exceed 60%, (ii) consolidated secured indebtedness will not exceed 40% of total asset value, (iii) tangible net worth will not be less than $745.4 million plus 75% of net equity proceeds received by us (other than proceeds received within ninety (90) days after the redemption, retirement or repurchase of ownership or equity interests in us up to the amount paid by us in connection with such redemption, retirement or repurchase, where, the net effect is that we shall not have increased our net worth as a result of any such proceeds), (iv) adjusted EBITDA (as defined in the unsecured revolving credit facility) to consolidated fixed charges will not be less than 1.50x, (v) the aggregate net operating income with respect to all unencumbered eligible properties to the portion of interest expense attributable to unsecured indebtedness will not be less than 1.75x, (vi) the ratio of total unsecured indebtedness to unencumbered asset value will not exceed 60%, and (vii) consolidated secured recourse indebtedness will not exceed 10% of total asset value (provided, however, this covenant shall not apply at any time after we achieve a debt ratings from at least two of Moody’s, S&P and Fitch, and such debt ratings are Baa3 or better (in the case of a rating by Moody’s) or BBB- or better (in the case of a rating by S&P or Fitch)).

The unsecured revolving credit facility contains customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates, and will require certain customary financial reports. The unsecured revolving credit facility contains customary events of default (subject in certain cases to specified cure periods), including but not limited to non-payment, breach of covenants, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, invalidity of loan documents, loss of real estate investment trust qualification, and occurrence of a change of control (defined in the definitive documentation for the unsecured credit facility).
