(2) A memorandum of understanding regarding postretirement health coverage mutually agreed upon through collective bargaining. This issue may not be subject to the impasse procedures set forth in Article 9 (commencing with Section 3548) of Chapter 10.7 of Division 4 of Title 1.

(d) No agreement reached pursuant to subdivision (a) shall be valid if it provides an employer contribution for employees with less than five years of credited service with the school employer. (e) The contracting agency shall provide, in the manner prescribed by the board, a notification of the agreement established pursuant to this section and any additional information necessary to implement this section.
