i know the LOI make's it confusing,but the wording seem's to be that B.Riley only get's a 30 day period of "exclusivity"..my take on that is that NHLD will not consider any other offer's during that 30 day's,which i think ends on December 30th,not the 31st
perhaps you're right and it does indicate the $3.25 per share cash offer will be accepted,i'm just not sure of it
