The rent shall be variable for each lease term set out in the contract; however, the first lease term rent shall be specified in the contract in a specific sum. The rent of every subsequent term shall be calculated before the commencement thereof according to a certain indicator or criterion that the parties to the contract have no influence over the determination of its price. Such indicator or criterion shall be based on a maximum and minimum limit to be stipulated in the contract. Where a lease term begins, the rent thereof shall not be variable.
