Your good friend Operetta tells you that she wants to open a jazz club and coffeehouse in her local community in Westchester County. She also tells you the following:

The landlord for the location where the coffeehouse is located wants to raise the rent and asked Operetta to meet to discuss the situation. The landlord has already provided a new five-page lease to Operetta. Before she signs the new lease, Operetta is anticipating that she will have to negotiate with the landlord on the issues of rent and why the coffeehouse would continue to be a good tenant for that location. The lease also provides that landlord should receive, monthly, 5% of the net revenue earned by the coffeehouse.

What law issues are raised by the facts above?
