Rule 504 of Regulation D provides an exemption from the registration requirements of the federal securities laws for some companies when they offer and sell up to $1,000,000 of their securities in any 12-month period.
A company can use this exemption so long as it is not a blank check company and does not have to file reports under the Securities Exchange Act of 1934. Also, the exemption generally does not allow companies to solicit or advertise their securities to the public, and purchasers receive "restricted" securities, meaning that they may not sell the securities without registration or an applicable exemption.
