Section 2-A-204. Formation in General

(1)  A  lease  contract  may  be made in any manner sufficient to show
  agreement, including  conduct  by  both  parties  which  recognizes  the
  existence of a lease contract.
    (2)  An  agreement  sufficient  to  constitute a lease contract may be
  found although the moment of its making is undetermined.
    (3) Although one or more terms are left open, a  lease  contract  does
  not fail for indefiniteness if the parties have intended to make a lease
  contract  and  there  is  a  reasonably  certain  basis  for  giving  an
  appropriate remedy.
