If I'm an employee of a company, and the company is caught doing something illegal (tax fraud), or caught up in a civil lawsuit, what is my liability as an employee and shareholder (we have stock options). I have no such prior knowledge of anything like this going on within the company; however, there are recent rumors going around and I'd like to ensure that as a standard employee with stock options (technically an "owner" of the company), that I'm not liable if someone on the management team did something stupid.
