"Aspire Capital has committed to purchase up to $25 million of Sunshine Heart's common stock from time to time as directed by the Company" which means that SSH gets to decided when to sell their stock own stock. Im guessing it will add about 1.5 to 2 million shares to the float eventually over the next two years. They definetely will not be selling shares in the 5's.
As low as they can , should support the stock price but at what price no one knows. My guess would be the recent lows of 5.25, in that area check for high volume purchases on the chart. I expect them to be very patient with their purchases.
