Under the Amended Loan Agreement, the Term Loans will amortize in quarterly installment payments in an aggregate annual amount equal to five percent (5%) of the original principal amount of the Term Loan Facility. The Facilities may be voluntarily prepaid at any time, in whole or in part, without penalty or premium, upon notice to the Administrative Agent; however, all amounts repaid or prepaid in respect of the Term Loans may not be reborrowed. The Term Loans will also be subject to mandatory prepayments in connection with certain debt issuances and asset sales, subject to certain reinvestment rights of the Borrowers. The Facilities have a maturity date of the fifth anniversary of the Amendment.
