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.

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 and/or the Term Loan 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%. The Term Loan prior to its repayment pursuant to a subsequent amendment to the Restated Credit Agreement bore interest at a rate equal to the sum of a base rate plus a margin of 0.45% to 1.25% or a LIBOR rate plus a margin of 1.45% to 2.25%.

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.

On December 14, 2020, we used a portion of the net proceeds from the Series I Notes, Series J Notes and Series K Notes (each as described below) to repay $75,000,000 of borrowings outstanding under our Restated Credit Agreement.

On December 4, 2020, we entered into a fifth amended and restated note purchase and guarantee agreement (the “Fifth Amended and Restated Prudential Agreement”) with Prudential and certain of its affiliates amending and restating our existing fourth amended and restated note purchase agreement. Pursuant to the Fifth Amended and Restated Prudential 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”) and (e) 3.52% Series F Guaranteed Senior Notes due September 12, 2029, in the aggregate principal amount of $50,000,000 (the “Series F Notes”) that were outstanding under the existing fourth restated prudential note purchase agreement would continue to remain outstanding under the Fifth Amended and Restated Prudential Agreement and we authorized and issued our 3.43% Series I Guaranteed Senior Notes due November 25, 2030, in the aggregate principal amount of $100,000,000 (the “Series I Notes” and, together with the Series A Notes, Series B Notes, Series C Notes, Series D Notes and Series F Notes, the “Notes”). On December 4, 2020, we completed the early redemption of our 6.0% Series A Notes due February 25, 2021, in the original aggregate principal amount of $100,000,000. As a result of the early redemption, we recognized a $1,233,000 loss on extinguishment of debt on our consolidated statement of operations for the year ended December 31, 2020. The Fifth Amended and Restated Prudential Agreement does not provide for scheduled reductions in the principal balance of the Series I Notes, or any of our previously issued Series B Notes, Series C Notes, Series D Notes, or Series F 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 December 4, 2020, we entered into a first amendment to note purchase and guarantee agreement (the “First Amended and Restated AIG Agreement”) with American General Life Insurance Company amending and restating our existing note purchase and guarantee agreement. Pursuant to the First Amended and Restated AIG Agreement, we agreed that 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”) that were outstanding under the existing note purchase and guarantee agreement would continue to remain outstanding under the First Amended and Restated AIG Agreement and we authorized and issued our $50,000,000 of 3.43% Series J Guaranteed Senior Notes due November 25, 2030 (the “Series J Notes”) to AIG. The First Amended and Restated AIG Agreement does not provide for scheduled reductions in the principal balance of the Series J Notes or any of our previously issued Series G Notes prior to their respective maturities.

On December 4, 2020, we entered into a first amended and restated note purchase and guarantee agreement (the “First Amended and Restated MassMutual Agreement”) amending and restating our existing note purchase and guarantee agreement. Pursuant to the First Amended and Restated MassMutual Agreement, we agreed that 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”) that were outstanding under the existing note purchase and guarantee agreement would continue to remain outstanding under the First Amended and Restated MassMutual Agreement and we authorized and issued our $25,000,000 of 3.43% Series K Guaranteed Senior Notes due November 25, 2030 (the “Series K Notes”) to MassMutual. The First Amended and Restated MassMutual Agreement does not provide for scheduled reductions in the principal balance of the Series K or any of our previously issued Series H Notes prior to their respective maturities.

We used the net proceeds from the issuance of the Series I Notes, Series J Notes and Series K Notes to prepay in full our Series A Notes due February 25, 2021, and repay $75,000,000 of borrowings outstanding under our Restated Credit Agreement.

The Notes, the Series E Notes, the Series G Notes, the Series H Notes, the Series I Notes, the Series J Notes and, the Series K Notes, respectively issued thereunder, are collectively referred to as the “senior unsecured notes.”

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 March 31, 2021, 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 March 31, 2021, scheduled debt maturities, including balloon payments, are as follows (in thousands):
