[1] Maturity dates represent the contractual maturity of each debt obligation. Repayment of securitized debt is a function of collateral cash flows which are disbursed in accordance with the contractual provisions of each trust, and is generally expected to occur prior to the maturity date above.

[2] The mezzanine loan carries a 10.50% per annum interest rate, of which 7.0% per annum may be deferred. The all-in cost of the mezzanine loan includes the amortization of deferred fees and expenses.
