“Nonissuer transaction” means any transaction not directly or indirectly for the benefit of the issuer. A transaction is indirectly for the benefit of the issuer if any portion of the purchase price of any securities involved in the transaction will be received indirectly by the issuer. An offering which involves both an issuer transaction and a nonissuer transaction shall be treated for the purposes of Chapters 2 (commencing with Section 25110) and 4 (commencing with Section 25130) of Part 2 of this division as an issuer transaction, but for the purposes of Chapter 1 (commencing with Section 25100) of Part 2 of this division they shall be treated as separate transactions.
