a. Senior Unsecured Revolving Credit Facility

Upon the completion of the IPO on February 11, 2015 we entered into a $400.0 million senior unsecured revolving credit facility with Citigroup Capital Markets Inc., Raymond James Bank, N.A. and Royal Bank of Canada, as joint lead arrangers and joint book running managers and Raymond James Bank, N.A. and Royal Bank of Canada, as co-syndication agents. This credit facility has an accordion feature that provides us with additional capacity, subject to the satisfaction of customary terms and conditions, of up to $250.0 million, for a total facility size of not more than $650.0 million. We intend to use the senior unsecured revolving credit facility to repay indebtedness, fund acquisitions, development and redevelopment opportunities, capital expenditures and the costs of securing new and renewal leases and provide working capital.

The Operating Partnership is the borrower under the senior unsecured revolving credit facility and we and certain of our subsidiaries that directly own certain of our properties are guarantors under the credit facility. The senior unsecured revolving credit facility will terminate in approximately three years. In addition, there will be two as-of-right extension options for the senior unsecured revolving credit facility and each extension option will allow us to extend the senior unsecured revolving credit facility for an additional six months, in each case subject to certain conditions and the payment of an extension fee.

Our senior unsecured revolving credit facility bears interest, at our option, either at:

•

a fluctuating rate equal to the sum of (a) the highest of (x) Citibank, N.A.’s base rate, (y) the federal funds effective rate plus 0.50% and (z) the one-month LIBOR rate plus 1.00% plus (b) a margin ranging from 0.4% to 0.9%, or

•

a Eurodollar rate equal to a periodic fixed rate equal to LIBOR plus, a margin ranging from 1.4% to 1.9%, in each case with a margin based on our leverage ratio.

Our senior unsecured revolving credit facility also contains certain customary financial covenants, as follows: (i) the maximum ratio of consolidated total indebtedness to total asset value (each as defined in the agreement) may not exceed 60.0% on any date, provided that the maximum ratio may be increased to 65.0% for the two consecutive quarters following the date on which a material acquisition (as defined in the agreement) occurs, (ii) the maximum ratio of consolidated secured indebtedness (as defined in the agreement) to total asset value may not exceed 40.0% on any date, (iii) the maximum ratio of consolidated secured recourse indebtedness (as defined in the agreement) to total asset value may not exceed 15% on any date, (iv) the minimum consolidated tangible net worth (as defined in the agreement) may not, on any date, be less than the sum of an amount equal to 75.0% of our consolidated tangible net worth as of the closing date of the facility plus an amount equal to 75.0% of the aggregate net cash proceeds received by us from any offering of our capital stock after the closing date of the facility, (v) the minimum ratio of adjusted consolidated EBITDA to consolidated fixed charges (each as defined in the agreement) may not be less than 1.50 to 1.00 on any date, (vi) the maximum ratio of consolidated unsecured indebtedness to unencumbered asset value (each as defined in the agreement) may not exceed 60% as of any date and (vii) the minimum ratio of adjusted consolidated net operating income from unencumbered assets (as defined in the agreement) to interest payable on unsecured debt (as determined in accordance with the agreement) shall not be less than 1.75 to 1.00 on any date. Additionally, under the revolving credit facility, our distributions may not exceed the greater of (i) 95.0% of our FFO or (ii) the amount required for us to maintain our status as a REIT and avoid the payment of federal or state income or excise tax.

Our senior unsecured revolving credit facility also includes customary limits on the percentage of our total asset value that may be invested in unimproved land, unconsolidated joint ventures, redevelopment and development assets (as defined in the agreement), loans, advances or extensions of credit and investments in mixed used assets and require that we obtain consent for mergers in which the company is not the surviving entity. These financial and restrictive covenants may limit the investments we may make and our ability to make distributions. As of December 31, 2016, we were in compliance with all financial and restrictive covenants under our senior unsecured revolving credit facility.

As of December 31, 2016, the weighted average interest rate payable on borrowings under our revolving credit facility was 2.15% and the weighted average annual interest rate for borrowings under our revolving credit facility was 1.89% for the year ended December 31, 2016. As of December 31, 2016, we had $212.2 million outstanding and $187.8 million available under our revolving credit facility. As of December 31, 2016 the fair value of our revolving credit facility approximated carrying value.

As of December 31, 2015, the weighted average interest rate payable on borrowings under our revolving credit facility was 1.75% and the weighted average annual interest rate for borrowings under our revolving credit facility was 1.62% for the year ended December 31, 2015.

c. Senior Unsecured Term Loan Facility

On September 29, 2016, we entered into a $100.0 million senior unsecured term loan facility (our “senior unsecured term loan facility”) with PNC Bank, National Association, as administrative agent, U.S. Bank National Association and SunTrust Bank, as syndication agents, PNC Capital Markets LLC, U.S. Bank National Association and SunTrust Robinson Humphrey, Inc., as joint lead arrangers and joint bookrunners.

The Operating Partnership is the borrower under our senior unsecured term loan facility and we and certain of our subsidiaries that directly own certain of our properties are guarantors under the term loan facility. The senior unsecured term loan facility matures on September 29, 2023, has a 180-day delayed draw period, and is prepayable without penalty beginning in October 2018.

Borrowings under our senior unsecured term loan facility will bear interest at floating rates equal to, at our option, either (1) a fluctuating rate equal to the sum of (a) the highest of (x) PNC Bank, National Association’s base rate, (y) the federal funds open rate plus 0.50% and (z) the daily Eurodollar rate plus 1.00% plus (b) a margin ranging from 0.7% to 1.35%, or (2) a Eurodollar rate equal to a periodic fixed rate equal to LIBOR plus, a margin ranging from 1.7% to 2.35%, in each case with a margin based on our leverage ratio. Based on our current leverage ratio, borrowings under our senior unsecured term loan facility will have an initial interest rate of LIBOR plus 170 basis points. We may prepay our senior unsecured term loan facility in whole or in part, subject to (i) customary costs, if any, of breaking LIBOR and, (ii) payment of a prepayment penalty equal to 2.0% of the principal balance being repaid during the first 12 months of our senior unsecured term loan facility and 1.0% of the principal balance being repaid during the following 12 months.

On October 27, 2016, we entered into two forward-starting interest rate swaps with an aggregate notional value of $100.0 million to effectively fix the interest rate on future draw downs under our senior unsecured term loan facility. The forward swaps have an effective date of March 29, 2017 and extend until the maturity of the term loan on September 29, 2023. The forward swaps will effectively fix the interest rate under our senior unsecured term loan facility at 3.12% annually based on the company’s current leverage ratio.

Our senior unsecured term loan facility also contains certain customary covenants, including but not limited to financial covenants that require us to maintain maximum ratios of consolidated total indebtedness, consolidated secured indebtedness and consolidated secured recourse indebtedness to total asset value, minimum consolidated tangible net worth and a minimum consolidated fixed charge ratio.

As of December 31, 2016 we have not drawn funds under our senior unsecured term loan facility.

d. Mortgage Notes Payable, Net

As part of the formation transaction, we completed the repayment or defeasance of, and full satisfaction with respect to, $293.4 million of secured nonrecourse mortgage loans.

The fair value of mortgage debt assumed at IPO was determined at the date of the formation transactions by discounting future contractual principal and interest payments using prevailing market rates at the date of the IPO. Subsequent to IPO we entered into debt associated with the acquisition of DEA – Pleasanton at fair value.

The fair value of mortgage debt was determined by discounting future contractual principal and interest payments using prevailing market rates. We deem the fair value measurement of our debt instruments as a Level 3 measurement. At December 31, 2016 and 2015 the fair value of our mortgage debt was $79.4 million and $82.7 million, respectively.
