“(i) Base Salary: The Company shall pay the Executive the equivalent of 12 months of the Executive’s annual base salary in effect at the time of the termination Without Cause or resignation with Good Reason in one lump sum payment, less standard deductions and withholdings.

(ii) Bonus: The Company shall pay the Executive a pro-rata portion of
