What i see from the form is that broker is not involved, ie direct sale by company to investor(s). The shares registered on form D cannot be sold for 1 year. Any special terms like warrants etc are either not disclosed or not allowed. Looks like there is an initial amount of $52,000 but some indefinite amount can be sold on this form.
I'm not an expert on this, just what I picked from reading the form and googling form D.
