For the purposes of this Act an exhibition is promoted for private gain if, and only if,—
any proceeds of the exhibition, that is to say, any sums paid for admission to the exhibition, or
any other sums (whenever paid) which, having regard to all the circumstances, can reasonably be regarded as paid wholly or partly for admission to the exhibition, or
where the exhibition is advertised (whether to the public or otherwise), any sums not falling within paragraph (b) above which are paid for facilities or services provided for persons admitted to the exhibition,

that any sums were paid for admission to the exhibition or to the premises at which it was given and that the exhibition was advertised to the public, or
that any sums were paid for facilities or services provided for persons admitted to the exhibition and that the exhibition was advertised (whether to the public or otherwise), or
that the amount of any payment falling to be made in connection with the promotion of the exhibition was determined wholly or partly by reference to the proceeds of the exhibition or any facilities or services provided for persons admitted to it,
the exhibition shall be deemed to have been promoted for private gain unless the contrary is shown.
Where an exhibition is promoted by a society which is established and conducted wholly for purposes other than purposes of any commercial undertaking and sums falling within subsection (1) above are applied for any purpose calculated to benefit the society as a whole, the exhibition shall not be held to be promoted for private gain by reason only that the application of those sums for that purpose results in benefit to any person as an individual.
