Accrued interest on the Promissory Note may be paid in cash or, if not paid in cash, may be added to the principal balance owed to the payee of the Promissory Note. The failure to make any payment under the Promissory Note when due and, with respect to payment of any interest (unless added to the principal balance owed to the payee of the Promissory Note), the continuation of such failure for a period of thirty days thereafter, constitutes an event of default under the Promissory Note.

As used herein, “Subordination Terms” means the subordination of payment of the Promissory Note to the prior payment in full in cash of the Credit Agreement.
