Input:  Person1:       Mr . Smith , I would like to get right to the point here . First , we need to talk about how much each company will pay .  
 Person2:Well , we want to have the largest share . Our company is much larger than yours , and we have been in business longer .  
 Person1:        Let's look at that another way . The major point is the value that we add , not who has been in business longer , or is bigger .  
 Person2:What are you thinking about ?  
 Person1:        We do not want to place ourselves in an inferior position . We are a good , small company---that's why you are interested .  
 Person2:Then , what would make you feel more comfortable ?  
 Person1:        If you take a 75 % position in the venture , we would take a back seat to you .
