When it is provided by law that a person shall be sentenced pursuant to this section, such person shall be sentenced to imprisonment for life and shall not be eligible for probation or suspension, modification or reduction of sentence. Except as otherwise provided in this section, in addition, a person sentenced pursuant to this section shall not be eligible for parole prior to serving 40 years' imprisonment, and such 40 years' imprisonment shall not be reduced by the application of good time credits. For crimes committed on or after July 1, 1999, a person sentenced pursuant to this section shall not be eligible for parole prior to serving 50 years' imprisonment, and such 50 years' imprisonment shall not be reduced by the application of good time credits. For crimes committed on or after July 1, 2006, a mandatory minimum term of imprisonment of 50 years shall not apply if the court finds that the defendant, because of the defendant's criminal history classification, would be subject to presumptive imprisonment pursuant to the sentencing guidelines grid for nondrug crimes and the sentencing range would exceed 600 months if the sentence established for a severity level 1 crime was imposed. In such case, the defendant is required to serve a mandatory minimum term equal to the sentence established for a severity level 1 crime pursuant to the sentencing range, the defendant shall not be eligible for parole prior to serving such mandatory minimum term of imprisonment, and such mandatory minimum term of imprisonment shall not be reduced by the application of good time credits.
