That is it,because at the end of the day,what the investor should be thinking is how the business should be able to move and bring in more revenue for the partners,else the issue of non disclosure should not be an issue.I want to believe that a nondisclosure agreement shouldn't be difficult for a good will investor to sign because the progress and well being of the business would be his heart desires. This agreement is to safe guard the idea against those whose intention might be to hurt you and your business.
