All payments of principal and interest on this Note shall be made by wire transfer of immediately available funds to an account designated by Payee in writing. If any payment of principal or interest on this Note is due on a day which is not a Business Day, such payment shall be due on the next succeeding Business Day, and such extension of time shall be taken into account in calculating the amount of interest payable under this Note.
