Then I'd say at the very least the friendship's over. You might look into hiring an attorney to defend yourself, but I wouldn't worry about it too much since their demand wouldn't have a legal leg to stand on being that there was never any written or signed agreement stating they were due any equity. Let them sue you & lose I guess. But then I'm no attorney, so don't take my word for it.
