(a)    Base Salary. The Executive’s annual base salary rate as of the date immediately preceding the Amendment Effective Date is $1,000,000 (the “Previous Base

5.Section 2(b) of the Employment Agreement (entitled “Incentive Compensation”) is hereby deleted and replaced with the following: “Except as otherwise provided in the following sentence, Executive shall not be entitled to any cash incentive compensation for periods after the Amendment Effective Date. For the 2021 performance year, the Executive shall be entitled to a cash incentive payment based upon actual achievement of the performance targets in effect for such performance year as approved by the Compensation Committee of the Board and prorated for the portion of the performance year completed as of the Amendment Effective Date.

10.The fact that the Executive has agreed to this Amendment shall not be considered to affect the Executive’s right to invoke the “Good Reason Process” pursuant to Section 4(e) of the Employment Agreement (entitled “Termination by the Executive”) based on either the modifications of the Executive’s position and duties pursuant to Section 1(b) of the Employment Agreement or the reductions in his compensation pursuant to Section 2 of the Employment Agreement.
