§490:3-108 Payable on demand or at definite
time. (a) A promise or order is "payable on demand" if it (i)
states that it is payable on demand or at sight, or otherwise indicates that it
is payable at the will of the holder, or (ii) does not state any time of
payment.
(b) A promise or order is "payable at a
definite time" if it is payable on elapse of a definite period of time
after sight or acceptance or at a fixed date or dates or at a time or times
readily ascertainable at the time the promise or order is issued, subject to
rights of (i) prepayment, (ii) acceleration, (iii) extension at the option of
the holder, or (iv) extension to a further definite time at the option of the
maker or acceptor or automatically upon or after a specified act or event.
(c) If an instrument, payable at a fixed date,
is also payable upon demand made before the fixed date, the instrument is
payable on demand until the fixed date and, if demand for payment is not made
before that date, becomes payable at a definite time on the fixed date. [L
