Article 2.5 (commencing with Section 2930) of Chapter 7 of Title 1 of Part 3 shall apply to reduce any minimum term in a state prison imposed pursuant to this section, but the person shall not otherwise be released on parole prior to that time.
  (2) Any person convicted of a felony specified in this subdivision who has served three or more prior separate prison terms, as defined in Section 667.5, for the crimes specified in subdivision (a) of this section shall be punished by imprisonment in the state prison for life without the possibility of parole.
  (b) This section shall not prevent the imposition of the punishment of death or imprisonment for life without the possibility of parole.

As used in this section, a commitment to the Department of the Youth Authority after conviction for a felony shall constitute a prior prison term. The term imposed under this section shall be imposed only if the prior prison terms are alleged under this section in the accusatory pleading, and either admitted by the defendant in open court, or found to be true by the jury trying the issue of guilt or by the court where guilt is established by a plea of guilty or nolo contendere or by a trial by the court sitting without a jury.
