(1)   imprisonment not exceeding 10 years; or
(2)   imprisonment in a local correctional facility not exceeding 2 years or a fine not exceeding $500 or both.
(b)   The discovery of one's spouse engaged in sexual intercourse with another does not constitute legally adequate provocation for the purpose of mitigating a killing from the crime of murder to voluntary manslaughter even though the killing was provoked by that discovery.
