Don't know if this helps. . .The February offering was tended under a Rule 506(b) exemption.
Rule 506(b) is a rule under Regulation D that provides conditions that an issuer may rely on to meet the requirements of the Section 4(a)(2) exemption. One of these conditions is that an issuer must not use general solicitation to market the securities.
“General solicitation” includes advertisements published in newspapers and magazines, public websites, communications broadcasted over television and radio, and seminars where attendees have been invited by general solicitation or general advertising. In addition, the use of an unrestricted, and therefore publicly available, website constitutes general solicitation. The solicitation must be an “offer” of securities, but solicitations that condition the market for an offering of securities may be considered to be offers.
