On June 10, 2016, the Operating Partnership, as borrower, and the Trust entered into an amended and restated Credit Agreement with KeyBank National Association, as administrative agent, KeyBanc Capital Markets Inc., BMO Capital Markets, and Citizens Bank N.A., as joint lead arrangers and co-book runners, BMO Capital Markets and Citizens Bank N.A., as co-syndication agents, and the lenders party thereto (the “Credit Agreement”) which increased the maximum principal amount available under an unsecured revolving credit facility from $750 million to $850 million. The Credit Agreement contains a term loan feature allowing the Operating Partnership to borrow in a single drawing before July 11, 2016 up to $250 million, increasing the borrowing capacity to an aggregate $1.1 billion.

The Credit Agreement has a maturity date of September 18, 2020 and includes a one year extension option. Borrowings under the Credit Agreement bear interest on the outstanding principal amount at a rate which is determined by the Trust’s credit rating, currently equal to LIBOR plus 1.20%. In addition, the Credit Agreement includes a facility fee equal to 0.25% per annum, which is determined by the Trust’s investment grade rating under the Credit Agreement.

The Credit Agreement includes a swingline loan commitment for up to 10% of the maximum principal amount and provides an accordion feature allowing the Trust to increase borrowing capacity by up to an additional $500 million, subject to customary terms and conditions, resulting in a maximum borrowing capacity of $1.6 billion.

The Credit Agreement contains financial covenants that, among other things, require compliance with leverage and coverage ratios and maintenance of minimum tangible net worth, as well as covenants that may limit the Trust’s and the Operating Partnership’s ability to incur additional debt or make distributions. The Trust may, at any time, voluntarily prepay any revolving or swingline loan under the Credit Agreement in whole or in part without premium or penalty. Prepayments of term borrowings require payment of premiums of up to 2.0% of the amount of prepayment, dependent on date of such prepayment. As of June 30, 2016, the Trust was in compliance with all financial covenants.

The Credit Agreement includes customary representations and warranties by the Operating Partnership and the Trust and imposes customary covenants on the Operating Partnership and the Trust. The Credit Agreement also contains customary events of default, and if an event of default occurs and continues, the Operating Partnership is subject to certain actions by the administrative agent, including without limitation, the acceleration of repayment of all amounts outstanding under the Credit Agreement.

The Credit Agreement provides for revolving credit and term loans to the Operating Partnership. Base Rate Loans, Adjusted LIBOR Rate Loans, and Letters of Credit (each, as defined in the Credit Agreement) will be subject to interest rates, based upon the investment grade rating of the Trust and the Operating Partnership as follows:



Credit Rating	Margin for Revolving Loans: Adjusted LIBOR Rate Loans and Letter of Credit Fee	Margin for Revolving Loans: Base Rate Loans		Margin for Term Loans: Adjusted LIBOR Rate Loans and Letter of Credit Fee	Margin for Term Loans: Base Rate Loans
