The warrants are 157M, period.
If, the O/S increases and the 157M warrants do not represent 25% of the O/S, then the lenders get more warrants up to that 25% value.
So unless the pps remain under $0.45 for the next 7 years, there will be 157M dilution, not "maybe 10M".
To be honest, we want the warrants exercised. Two reason; one - we need the cash, and 2 - it means the pps has risen higher.
