[1] Beginning July 1, 2023, one-month London Inter-Bank Offered Rate (“LIBOR”) is no longer published and all remaining debt referencing LIBOR was replaced with the Secured Overnight Financing Rate (“SOFR”).

[2] The interest rate for the Basis Term Loan is the greater of (i) SOFR plus 3.97% per annum and (ii) 6.125% per annum. On November 23, 2022, the Company entered into an interest rate cap agreement to cap the SOFR interest rate at 4.65% effective January 1, 2023, which replaced the existing interest rate cap agreement that capped the SOFR interest rate at 3.5%.

[3] The outstanding balance includes less than $0.1 million and $0.3 million of exit fees at December 31, 2023 and 2022, respectively.

[4] The Company has entered into an interest rate swap which fixes the interest rate of this loan at 4.06%. On May 3, 2023, the Hollinswood loan agreement was amended to replace LIBOR with SOFR, effective July 1, 2023.

[5] On June 28, 2023, the Company entered into an agreement to amend the interest rate to 7.73% and extend the maturity date of this loan to June 24, 2024.

[7] On May 5, 2023, the Company refinanced the Highlandtown Village Shopping Center Loan to extend the maturity date to May 10, 2028 and entered into an interest rate swap which fixes the interest rate of the new loan at 6.085% as described below under the heading “—Mortgage Indebtedness”. The prior loan carried an interest rate of 4.13%.
