How can he get out?
If the claims are of one party to an agreement turn out to be false, then standard representations and warranties of contract would provide outs in most circumstances. Other terms may exist as to whether, or if, a party might cancel for reasons other than breaches.
As for your inferences about the Montana DEQ, why would they keep testing wells, at their own expense, if there were no possibilities? Maybe the wells are shit. But the fact that they keep testing them (and producing oil when they test them) seems to indicate, that the Forward people are foolish dreamers who believe their own story, not fraudulent scammers (They could be fraudulent scammers, but, talk about a long con. Form a company, find some wells, drill out the plugs, buy some fake oil and sell it and pay taxes on it to Montana, just to find MEDT five years later to get their hands on all that MEDT cash. Wow! These guys are good!).
How about this one for size? What if they are right, what if standard pumping equipment is insufficient, what if?
Pinksheet companies are ALL ABOUT "what if." If they weren't, you would be an idiot to invest in any of them. Period. If the potential for massive increases wasn't there as an incentive you should go 100% bluechip and stay away from the pinks.
I have no idea whether Forward/MEDT will succeed or fail, but neither do you. They only announced this thing a week ago, yet all of you are CERTAIN they are liars or idiots. You distort facts, contrive misstatements and search, wherever you can for something to pick on or at. Leave them alone to succeed or fail and then wear your shame or your "I told you so" faces when the facts are in. Whatever they may be.
Have a nice day.
