Surprised no one has said it, but find an IP lawyer who specialises in negotiations. Seriously, a few $$$$ now could save you heaps. I did the same thing (worldwide exclusivity) when I was young and naive, and there were no "minimum sales" targets set. The company who now owned the code sold none in the first year despite being well connected and rich. I managed to wrestle the IP off them via free consulting, and within a week had my first "enterprise" client. Make sure if you sign something you get minimum sales volumes written into the contract, as well as who gets what once the money comes in. Anyone who has ever set up a distributor or partnered with a company will tell you the same thing.
