SEVERANCE

Upon a termination without Cause (as defined below) or by you for Good Reason (as defined below), and subject to execution of a release of claims in a form reasonably provided to you by Clarios, you will be provided with one-and-one-half (1.5) times the sum of your annual base salary and your annual bonus target amount, payable in a lump sum within 30 days following termination. For the period of 1.5 years (18 months), benefit continuation (medical/dental/vision) will be covered by the Company at the current employee contribution levels. You also will receive any unpaid prior year bonus, to the extent earned under the AIPP for such year, payable at the same time as such year’s bonuses are paid to other senior executives. Senior executive-level outplacement services provided for a period of 1 year (12 months).
