Italian to English Law/Patents Law: Contract(s)

Hello everyone,

I am trying to translate this phrase into English, but I'm facing some problems as it is not a standard contract. Basically it's for a franchising, but some of the clauses are different. "Partnership esclusiva" is meant in the sense that whoever opens a shop with their products, will only sell the company products and no other brand. "Contratto commerciale" I think it's "trade agreement", but combined I can't figure it out...My legal dictionary suggests also "exclusive dealing" as "contratto di esclusiva", but also in this case I am not sure it's the same thing...Anyone can help?
Thanks!
