Yes ozz there is risk everywhere but when erx has managed to spend tons of cash pass the hat over and over and failed to deliver on the 2004 news it makes you wonder. Furthermore it is more the exception than the rule that big pharma buys any tech that has not even been through phase I. Erx would need to be oustanding and they have been around for a few years now and nothing, so if that is what they are depending on or further funding from shareholders it does not look good at all. Anyway Good luck I could be wrong
