Dear Eric:

Codex DNA, Inc. (the “Company”) is pleased to offer you the position of Chief Operating Officer, reporting to Todd R. Nelson, CEO. Your anticipated start date will be June 1, 2022 (your “Start Date”) or mutually agreed upon start date. This offer and your employment relationship will be subject to the terms and conditions of this letter.

If you decide to join us, your salary will be $350,000 per year, less applicable withholdings, paid in accordance with the Company’s normal payroll practices. Future adjustments in compensation, if any, will be made by the Company in its sole and absolute discretion. This is an exempt position, which means you are paid for the job and not by the hour. Accordingly, you will not receive overtime pay if you work more than 8 hours in a workday or 40 hours in a workweek.

You will be eligible to participate in the Company’s 2022 Annual Performance Incentive Plan as it may be adopted and amended from time to time in the Company’s sole and absolute discretion. Your initial annual bonus target will be 40% of your base salary, which, to the extent earned, will be paid following the end of the calendar year, but in no event later than April 15th of the year following the year in which it is earned. Eligibility and the amount of the bonus will be dependent on milestones and goals as set forth in the current bonus program. In addition, you must be in good standing with the Company to be eligible to receive a bonus.

You will also be eligible for all benefits available to other full-time Company employees, including medical, dental insurance, 401(k) plan, etc., in accordance with the Company benefit plans. As an executive of the company, you will participate in the Change in Control and severance programs previously approved by our Board. Company reserves the right to change or eliminate these benefits on a prospective basis at any time.

In addition, we will recommend to the Company’s Board of Directors that you be granted an option to purchase 225,000 shares of Common Stock in accordance with the Company’s Stock Incentive Plan (the “Plan”) and related option documents. You will be required to acknowledge the Incentive Stock Option Agreement (“the Agreement”) and the options will be subject to the terms and conditions of the Plan and the Agreement.

The Company also agrees to reimburse you up to twenty thousand dollars ($20,000) in relocation expenses once receipts or other appropriate documentation is provided. Company will reimburse this amount in consideration of you having remained employed with the Company for a period of one (1) year after your Start Date (the “Retention Period”). Because Company is reimbursing this money to you in anticipation of retaining your services for the Retention Period, in the event you should voluntarily resign your employment with Company for any reason or Company terminates your employment for cause prior to the end of the Retention Period, you agree to repay the

In addition, you agree that you will not disclose to Company, or induce Company to use, any confidential or proprietary information or material belonging to any previous employer or others. You agree not to enter into any agreement, whether written or oral, in conflict with your promises in this provision.
