Ann: Letter to Shareholders, page-5

Their shares remain in escrow until final payment is received so if they want to on sell it, they'll need to pay up all money first.
With $5 mil in the bank and another $8 mil a year for 3 years, puts them in a great position to find something at home or partner up with someone who is project rich and cash poor and have a great supply of cash to push ahead at pace.
I hope that's how they're looking at it.
