(5) Any member who is a correctional officer or a probation and parole officer employed by the Department of Corrections at the time of retirement and who retires on or before June 30, 2000, shall be entitled to receive an annual retirement benefit equal to two and one-half percent (2 1/2%) of the final average compensation of the member not to exceed Twenty-five Thousand Dollars ($25,000.00) and two percent (2%) of the final average salary in excess of Twenty-five Thousand Dollars ($25,000.00) but not exceeding the maximum compensation level as provided in paragraph (9) of Section 902 of this title, multiplied by the number of years of service as a correctional officer or a probation and parole officer, provided, any years accrued prior to July 1, 1990, as a correctional officer or a probation and parole officer by a member who is employed as a correctional officer or a probation and parole officer on July 1, 1990, shall be calculated for retirement purposes at two and one-quarter percent (2 1/4%) of the final average compensation of the member not to exceed Twenty-five Thousand Dollars ($25,000.00) and two percent (2%) of the final average salary in excess of Twenty-five Thousand Dollars ($25,000.00) but not exceeding the maximum compensation level as provided in paragraph (9) of Section 902 of this title, multiplied by the number of years of such service and any years in excess of twenty (20) years as such an officer or years credited to the member in accordance with the provisions of Section 913 of this title shall be calculated for retirement purposes at two percent (2%) of the final average compensation of the member multiplied by the number of years of such service.

(8) Any person who contributed to the System as a correctional officer, a probation and parole officer or a fugitive apprehension agent as provided in paragraphs (b) or (c) of subsection (1) of Section 919.1 of this title, and who retires under normal retirement or early retirement on or after January 1, 2004, under paragraph (24) of Section 902 of this title, and any public safety officer described by paragraph (37) of Section 902 of this title hired on or after the effective date of this act by the Grand River Dam Authority and who retires on or after the effective date of this act, shall have retirement benefits for each year of full-time-equivalent participating service as a correctional officer, a probation and parole officer or a fugitive apprehension agent, or Grand River Dam public safety officer computed on two and one-half percent (2 1/2%) of the final average compensation based upon those years as a correctional officer, a probation and parole officer, a fugitive apprehension agent or a Grand River Dam public safety officer.
