3

(iii) The Company shall pay to the Executive a monthly cash payment for nine (9) months in an amount equal to the monthly employer contribution that the Company would have made to provide health insurance to the Executive if the Executive had remained employed by the Company.

The amounts payable under Section 3(i) and (iii) of this Separation Agreement shall be paid out in substantially equal installments in accordance with the Company’s payroll practice over nine (9) months; provided that the initial payment shall include acatch-up payment to cover amounts retroactive to the day immediately following the Last Date of Employment. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury RegulationSection 1.409A-2(b)(2).

The 2018 Bonus shall be paid out in a lump sum when such amount is actually determined and annual bonuses are paid out to the Company’s executives for 2018, provided that the 2018 Bonus shall be paid no later than March 15, 2019.
