"Commitment" or not, when that drop dead date hits and the SP is still below, it will be delisted. Also, you are incorrect about this commitment. What you said makes absolutely NO sense!
It's the same as being in a club. Either you pay your dues by a specified date, or you're no longer a member. Cut & dry! Why would the club require some kind of commitment when you are the one that WANTS/NEEDS the club, and NOT the other way around? The only things REQUIRED is that Mullen have a way to get back to $1 (they may also consider other factors, such as the company's fundamental financial strengths and weaknesses, the overall market conditions, the company's historical bid price, and impending disclosures, corporate actions and strategic business plans that the company believes may impact its bid price), AND that Mullen goes into the NASDAQ listing center at least 15 days prior to the execution date and add an event notification for the pending RS.
