Upon such funding by the Administrative Agent, the Borrower shall be obligated to such Term C Lender in respect of the full principal amount of its Term C Loan (in the amount of its Term C Commitment) on the terms and conditions of this Agreement and the Credit Agreement, as supplemented by this Agreement. Additional Term Borrowings under the Term C Facility are sometimes referred to herein and in the other Loan Documents as “Term C Borrowings”.
