By the end of January the ESS deal with cost AMBS $8.2 million in cash and an additional $3 million in stock. So you are correct in what you just posted.
Below is a link that breaks down this deal. Let's see if the market will agree that ESS is worth .21 a share when the deal is finalized.
I would expect by now, there are many institutional buyers watching this very closely. With what AMBS has in the works now, there should not be much difficulty in getting more funding / financing approved.
