Mr.Twenton, I think a seller could...
I am not a security lawyer, but I don't think there would be anything wrong with an Oppenheimer, for example, agreeing to sell their 15% to GE as I believe they did, BUT under an agreement that they receive any increase in bid price that may occur. I would not be surprised if GE has negotiated such arrangements with others. They are still bound to offer everyone the same price but if they increase it, than they would have to pay the large holders who came in early the higher price... it's just speculation on my part so take it with a huge grain of salt..
Cheers
