1.Position. You will have the position of Senior Vice President, Operations and will continue to be based from your home in Andover, MN, making regular trips to the Company’s plants in Columbia, MS and Devault, PA and headquarters in El Segundo, CA. Your manager is Ethan Brown.

2.Base Salary. Your base salary will be increased to the gross amount of $355,000 per year, payable on the Company’s regular payroll dates. This is an Exempt position and you are ineligible for overtime.

3.Annual Discretionary Bonus. You will continue to be eligible to earn an annual discretionary bonus in effect for the applicable fiscal year, on the terms and subject to the conditions set forth in the Offer Letter, including the annual discretionary bonus target for the fiscal year of 40% of your base salary. For purposes of clarity, the base salary used to determine any applicable bonus will be the base salary in effect on the date such bonus is determined.

4.Retention Award. Subject to the approval of the Human Capital Management and Compensation Committee (the “Compensation Committee”), you will be granted an award of restricted stock units valued at $250,000 (the “RSU Award”) under the Company’s 2018 Equity Incentive Plan (as such plan may be amended and restated from time to time, the “Plan”). The number of shares subject to the RSU Award will be determined by dividing the dollar value of the RSU Award by the Closing Price and rounding up to the nearest whole number of shares. The Closing Price shall equal the closing price of the Company’s Common Stock as reported on the NASDAQ Global Select Market for the date of grant. We expect the RSU Award to be granted to you the next time the Compensation Committee approves equity awards pursuant to the Plan. The RSU Award will generally be subject to the terms and conditions of the Plan and the applicable RSU agreement and will vest and become non-forfeitable with respect to 1/4th of the total shares subject to the RSU Award on each quarterly anniversary of the date of grant, such that the RSU Award will be fully vested 1 year after the date of grant, subject to your continuous service through each vesting date, as described in the applicable RSU agreement.
