My immediate thought exactly. You'd have to be absolutely flat broke for this to make any sense whatsoever. Why sell it at all? And, if it's so worthless, wouldn't you be more than a bit suspicious if the CEO were so keen to buy it off you? Something here smells off to me.
I assume the deal was for something else... Eg. "Sign this deal for 100 bucks and we'll have a shorter list of people to consult at every shareholders meeting. In return, we'll consider you for investment opportunities for your next startup "
