THE ISP WELFARE BENEFITS PLAN, SUMMARY PLAN DESCRIPTION, APPENDIX C

1/8/2023 01/8/2027

The providers for the union medical, prescription drug, dental and vision programs will be consistent with the providers for the company medical, prescription drug, dental and vision programs contingent that the provider maintains the existing plan design for the union report.

If the company maintains Anthem BC/BS & Express Scripts for the company medical and prescription drug program(s), the union agrees that the provider for the union medical and prescription drug programs will follow the company national account provider for Anthem BC/BS & Express Scripts during any benefit year that the company retains Anthem BC/BS & Express Scripts coverage for its other company medical and prescription drug program(s).

If the company does not retain Anthem BC/BS & Express Scripts medical and prescription drug coverage for its other company medical and prescription drug program(s), and the disruption analysis is greater than two percent, it will retain the current BC/BS provider for the union medical and Express Scripts for the prescription drug plan.

The company will provide the union the disruption report as soon as possible prior to the next benefit year for implementation.
