A reference in this Act to, or to the making of, an offer to the public or to, or to the issuing of, an invitation to the public is, unless the contrary intention appears, to be construed as including a reference to, or to the making of, an offer to any section of the public or to, or to the issuing of, an invitation to any section of the public, as the case may be, whether selected as clients of the person making the offer or issuing the invitation or in any other manner and notwithstanding that the offer is capable of acceptance only by each person to whom it is made or that an offer or application may be made pursuant to the invitation only by a person to whom the invitation is issued, but a bona fide offer or invitation is not taken to be an offer or invitation to the public if it:
(a) is an offer or invitation to enter into an underwriting agreement; or
(b) is made or issued to a person whose ordinary business is to buy or sell shares, debentures or interests in managed investment schemes, whether as principal or agent; or
(c) is made or issued to existing members or debenture holders of a corporation and relates to shares in, or debentures of, that corporation; or
(d) is made or issued to existing members of a company in connection with a proposal referred to in section 507 and relates to shares in that company.
