employment with the Company and the actual bonus the Executive received during the first year of employment with the Company if such termination under this Subsection (c) occurs in the second year of employment with the Company.  However, the amount of the severance payment under this Subsection (c) shall be reduced by the amount of any severance pay or pay in lieu of notice that the Executive receives from the Company under a federal or state statute (including, without limitation, the Worker Adjustment and Retraining Notification Act). 

(d)Commencement of Severance Payments.  Payment of the severance pay provided for under this Agreement will be made on the first regularly scheduled payroll date that occurs on or after 60 days after the Executive’s Separation, but only if the Executive has complied with the release and other preconditions set forth in Subsection (a) (to the extent applicable).
