The shares can be sold or not sold on any schedule for 90 days after the Trans. Date From entry. Another block for each holder of no more than 1% of the total outstanding shares can be sold by a subsequent filing after the 90-day period.
The three people who filed the Form 144 have a 90 days period, after the filing, to sell the 1,380,000 shares. This could be after they get the free shares. I would think that they are getting ready to sell the shares after they get the free shares.
