The first installment shall be due and payable on April 7, 2014, and a like installment shall be due and payable on the same day of every second week thereafter until this note shall have been fully paid and satisfied. All interest shall accrue and be paid at maturity. Notwithstanding the foregoing, upon the earlier of
