What you've said makes perfect sense to me. I can't imagine that the "unsolicited interest" has taken the form of "ok Falcon, if Hess elect not to go ahead we'll give you the same deal but we'll only expect 60% (or insert any other number below 62.5%)".
It seems much more likely that Falcon has been approached by majors saying, "if Hess doesn't go ahead we'd be interested in buying out FOA".
Personally, if that meant a 10 or 20 bagger now rather than a potential 40-bagger down the road I'd be happy to take it seeing as there's still the promise of Hungary and SA to come.
Four years of heartache and my nerves of steel are ready for a break!!
