Okla. Stat. tit. 36, § 36-1213: Immunity from prosecution

If any person shall ask to be excused from attending and

testifying or from producing any books, papers, records,

correspondence or other documents at any hearing on the ground that

the testimony or evidence required of the person may tend to

incriminate the person or subject the person to a penalty or

forfeiture, and shall notwithstanding be directed to give such

testimony or produce such evidence, the person must nonetheless

comply with such direction, but shall not thereafter be prosecuted

or subjected to any criminal penalty of forfeiture for or on account

of any evidence which the person may testify or produce pursuant

thereto. No testimony so given or evidence produced shall be

received against the person upon any criminal action, investigation

or proceeding; provided, however, individuals so testifying shall

not be exempt from prosecution or punishment for any perjury

committed by them while so testifying and the testimony or evidence

so given or produced shall be admissible against them upon any

criminal action, investigation or proceeding concerning such

perjury, and such individuals shall not be exempt from the refusal,

revocation or suspension of any license, permission or authority

conferred, or to be conferred, pursuant to the insurance law of this

state.
