I do appreciate everyone's efforts to help, but it really would be most helpful if someone who's been party to a technology licensing agreement would share with me specifically what the exit clause determining when to stop paying royalties was.
I can sit down with this fellow and work things out from scratch (though it will involve an expensive plane trip, especially if I bring the lawyer along, so I'd like to do my homework in advance), but I'd feel a lot better going into it with some solid ideas. A few real data points would be very useful.
John Woodgate's suggestion to put a time limit on the royalty agreement with an arbitration clause at the end does seem like one reasonable approach. I'm wondering if there are other approaches that have been successfully used by folks here.
Thanks!
