Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

10% Stockholder regulatory

"10% Stockholder"

Gift from Affiliate regulatory

"Gift from Affiliate"

FBO technical

"VENDROW CHILDREN'S TRUST FBO DAVID G VENDROW"

FBO (short for "for benefit of") indicates that funds or assets are held by one party — such as a bank, broker, or trustee — on behalf of another person or entity who is the true owner. It matters to investors because it clarifies who ultimately has the right to the assets, who bears the risk if something goes wrong, and how money moves or is reported; think of it like a safety deposit box held by a bank for a named customer.
