What this framework is
Rule 506(b) is an exemption from Securities Act registration for offerings without general solicitation. It does not cap the offering amount and can permit accredited investors plus up to 35 non-accredited purchasers who, alone or with a purchaser representative, meet the applicable sophistication standard.
Whether a communication is general solicitation and whether an offeree relationship is sufficient are fact-specific legal questions. Do not advertise or make offers until securities counsel has reviewed the planned channels, audience, and offering procedures.
