$24 million does seem to be a hefty price IF the deal goes through.
I am not concerned about it though because it is just an option agreement at this time.
Orbite have to pay a little over a million for the right to do all of their research as to wether they want to close the deal under these terms.
If it turns out not to be as profitable as they hope then they just don't close the deal.
At that point they will know the facts and can either cancel the deal in its' entirety and move on, or try to renegotiate the price down to where it makes economic sense for Orbite.
The only gamble right now is the entry fee and it is not really very much money to be putting out in order to get the real facts.
I don't think it is anything to get worked up about at this point. Lots of time for this to be worked out.
