[1] The interest rate for the Basis Term Loan was the greater of (i) the Secured Overnight Financing Rate (“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%.

[2] Interest rates are as of March 31, 2024.

[3] The outstanding balance includes less than $0.1 million of exit fees at each of March 31, 2024 and December 31, 2023. On April 30, 2024, the Company paid off the outstanding principal balance on the Basis Term Loan with a portion of the proceeds of a new loan secured by the properties that were collateral for the Basis Term Loan.

[4] The Company has entered into an interest rate swap which fixes the interest rate of this loan at 4.06%.

[5] On February 8, 2024, the Company refinanced the Vista Shops at Golden Mile Loan to extend the maturity date to February 8, 2029 and entered into an interest rate swap which fixes the interest rate of the new loan at 6.90%.

[6] The Company has entered into an interest rate swap which fixes the interest rate of this loan at 6.085%.

[7] The outstanding balance reflects the fair value of the debt.

[8] A portion of the interest on this loan is paid in cash (the “Current Interest”) and a portion of the interest is capitalized and added to the principal amount of the loan each month (the “Capitalized Interest” and, together with the Current Interest, the “Mezzanine Loan Interest”). The initial Mezzanine Loan Interest rate was 12% per annum, comprised of a 5% Current Interest rate and a 7% Capitalized Interest rate. The Capitalized Interest rate increases each year by 1%.

[9] On May 1, 2023, the Company terminated this loan’s prior interest rate swap and entered into a new interest rate swap agreement to fix the interest rate at 5.85%.
