THERE IS NO DILUTION. You FIRST need an 8K-A 1.01 AGREEMENT Saying AMBS secured convertible debentures in principal amount of a total of $XXX,XXX (the "Debentures") from a 3rd party. Then there is a maturing period and AMBS could put in an anti-dilution provision. Then, once the company wants to swap shares for cash an 8k-a 3.02 sale of equity is issued within 2 days of the executed trades.
Firstly, i haven't seen any that will affect PPS. Plus if there was an agreement issued NOW in a 8.01 8k-a that debenture would probably be matured months and months from now.
