Those are grants, so they don't really have to pay for those until they sell (unless otherwise negotiated). Normally this would be either you pay at the vesting date, a year from now. Or, they sit as grants until sold and the cost basis is factored in at that time.
But notice, a few of them have a strike price of .60. I wonder if the ones that didn't have that listed, have a different price.
It is a promising sign though, that their senior leadership is being well-positioned to prosper if the company prospers.
