On June 2, 2015, we entered into a $225,000,000 senior unsecured credit agreement (the “Credit Agreement”) with a group of banks led by Bank of America, N.A. The Credit Agreement consisted of a $175,000,000 unsecured revolving credit facility (the “Revolving Facility”) and a $50,000,000 unsecured term loan (the “Term Loan”).

On March 23, 2018, we entered into an amended and restated credit agreement (as amended, the “Restated Credit Agreement”) amending and restating our Credit Agreement. Pursuant to the Restated Credit Agreement, we (a) increased the borrowing capacity under the Revolving Facility from $175,000,000 to $250,000,000, (b) extended the maturity date of the Revolving Facility from June 2018 to March 2022, (c) extended the maturity date of the Term Loan from June 2020 to March 2023 and (d) amended certain financial covenants and provisions.

On September 19, 2018, we entered into an amendment (the “First Amendment”) of our Restated Credit Agreement. The First Amendment modifies the Restated Credit Agreement to, among other things: (i) reflect that we had previously entered into (a) an amended and restated note purchase and guarantee agreement with The Prudential Insurance Company of America (“Prudential”) and certain of its affiliates and (b) a note purchase and guarantee agreement with the Metropolitan Life Insurance Company (“MetLife”) and certain of its affiliates; and (ii) permit borrowings under each of the Revolving Facility and the Term Loan at three different interest rates, including a rate based on the LIBOR Daily Floating Rate (as defined in the First Amendment) plus the Applicable Rate (as defined in the First Amendment) for such facility.

On September 12, 2019, in connection with prepayment of the Term Loan, we entered into a consent and amendment (the “Second Amendment”) of our Restated Credit Agreement. The Second Amendment modifies the Restated Credit Agreement to, among other things, (a) increase our borrowing capacity under the Revolving Facility from $250,000,000 to $300,000,000 and (b) decrease lender commitments under the Term Loan to $0.

Subject to the terms of the Restated Credit Agreement and our continued compliance with its provisions, we have the option to (a) extend the term of the Revolving Facility for one additional year to March 2023 and (b) request that the lenders approve an increase of up to $300,000,000 in the amount of the Revolving Facility to $600,000,000 in the aggregate. The Restated Credit Agreement incurs interest and fees at various rates based on our total indebtedness to total asset value ratio at the end of each quarterly reporting period. The Revolving Facility permits borrowings at an interest rate equal to the sum of a base rate plus a margin of 0.50% to 1.30% or a LIBOR rate plus a margin of 1.50% to 2.30%. The annual commitment fee on the undrawn funds under the Revolving Facility is 0.15% to 0.25%.

On September 12, 2019, we entered into a fourth amended and restated note purchase and guarantee agreement (the “Fourth Restated Prudential Note Purchase Agreement”) amending and restating our existing senior note purchase agreement with Prudential and certain of its affiliates. Pursuant to the Fourth Restated Prudential Note Purchase Agreement, we agreed that our (a) 6.0% Series A Guaranteed Senior Notes due February 25, 2021, in the original aggregate principal amount of $100,000,000 (the “Series A Notes”), (b) 5.35% Series B Guaranteed Senior Notes due June 2, 2023, in the original aggregate principal amount of $75,000,000 (the “Series B Notes”), (c) 4.75% Series C Guaranteed Senior Notes due February 25, 2025, in the aggregate principal amount of

$50,000,000 (the “Series C Notes”) and (d) 5.47% Series D Guaranteed Senior Notes due June 21, 2028, in the aggregate principal amount of $50,000,000 (the “Series D Notes”) that were outstanding under the existing senior note purchase agreement would continue to remain outstanding under the Fourth Restated Prudential Note Purchase Agreement and we authorized and issued our 3.52% Series F Guaranteed Senior Notes due September 12, 2029, in the aggregate principal amount of $50,000,000 (the “Series F Notes” and, together with the Series A Notes, Series B Notes, Series C Notes and Series D Notes, the “Notes”). The Fourth Restated Prudential Note Purchase Agreement does not provide for scheduled reductions in the principal balance of the Notes prior to their respective maturities.

On June 21, 2018, we entered into a note purchase and guarantee agreement (the “MetLife Note Purchase Agreement”) with MetLife and certain of its affiliates. Pursuant to the MetLife Note Purchase Agreement, we authorized and issued our 5.47% Series E Guaranteed Senior Notes due June 21, 2028, in the aggregate principal amount of $50,000,000 (the “Series E Notes”). The MetLife Note Purchase Agreement does not provide for scheduled reductions in the principal balance of the Series E Notes prior to their maturity.

On September 12, 2019, we entered into a note purchase and guarantee agreement (the “AIG Note Purchase Agreement”) with American General Life Insurance Company. Pursuant to the AIG Note Purchase Agreement, we authorized and issued our 3.52% Series G Guaranteed Senior Notes due September 12, 2029, in the aggregate principal amount of $50,000,000 (the “Series G Notes”). The AIG Note Purchase Agreement does not provide for scheduled reductions in the principal balance of the Series G Notes prior to their maturity.

On September 12, 2019, we entered into a note purchase and guarantee agreement (the “MassMutual Note Purchase Agreement”) with Massachusetts Mutual Life Insurance Company and certain of its affiliates. Pursuant to the MassMutual Note Purchase Agreement, we authorized and issued our 3.52% Series H Guaranteed Senior Notes due September 12, 2029, in the aggregate principal amount of $25,000,000 (the “Series H Notes”). The MassMutual Note Purchase Agreement does not provide for scheduled reductions in the principal balance of the Series H Notes prior to their maturity.

The Restated Credit Agreement and our senior unsecured notes contain customary financial covenants such as leverage, coverage ratios and minimum tangible net worth, as well as limitations on restricted payments, which may limit our ability to incur additional debt or pay dividends. The Restated Credit Agreement and our senior unsecured notes also contain customary events of default, including cross defaults to each other, change of control and failure to maintain REIT status (provided that the senior unsecured notes require a mandatory offer to prepay the notes upon a change in control in lieu of a change of control event of default). Any event of default, if not cured or waived in a timely manner, would increase by 200 basis points (2.00%) the interest rate we pay under the Restated Credit Agreement and our senior unsecured notes, and could result in the acceleration of our indebtedness under the Restated Credit Agreement and our senior unsecured notes. We may be prohibited from drawing funds under the Revolving Facility if there is any event or condition that constitutes an event of default under the Restated Credit Agreement or that, with the giving of any notice, the passage of time, or both, would be an event of default under the Restated Credit Agreement.

As of June 30, 2020, we are in compliance with all of the material terms of the Restated Credit Agreement and our senior unsecured notes, including the various financial covenants described herein.

As of June 30, 2020, scheduled debt maturities, including balloon payments, are as follows (in thousands):
