There's not much they can do. The negotiations come down to take it or leave it. With only 3 guys in an undesirable area they might be able to push back some. They just need to agree not to bid on each other's area if there is an impasse. Let the time table expire and go at it again. There's just the chance they could lose it all that way, but I doubt many outside investors are knocking down the door in your area.
