Good advice from the previous posts but remember, you might have to play hardball on the negotiations as the more restrictions you add, most likely the other party will begin to lessen your bonus money and your % royalty. I have found this to be the case in my past dealings so you might want to market your minerals to some extent if this is the case. Remember, don't be in a hurrry to sign anything as this will be your first mistake.
