No person shall be excused from testifying or from producing any books, accounts, papers, records, or documents in any investigation or inquiry by, or upon any hearing before, the division or member thereof when ordered to do so by the division or member, upon the ground that the testimony or evidence, accounts, papers, records, books, or documents, required of him or her may tend to incriminate him or her or subject him or her to penalty or forfeiture; but no person shall be prosecuted, punished, or subjected to any penalty or forfeiture for or on account of any act, transaction, matter, or thing concerning which he or she shall, under oath, by order of the division or a member thereof, have testified or produced the documentary evidence; provided, that no person so testifying shall be exempt from prosecution or punishment for any perjury committed by him or her in his or her testimony. Nothing contained in this section is intended to give or shall be construed as in any manner giving any corporation immunity of any kind from the law.
