The schedule for working together will be determined within 2 weeks of signing this letter.

Compensation: Your base compensation will be $290,000 on an annualized basis once you are working full time.

In general, the IPO bonus will be paid out at $1 M+ in stock/cash, assuming parameters are achieved in timing, size of financing, and valuation as deemed acceptable by the Board of Directors. This financing bonus can be paid in cash or stock as determined appropriate by the Board of Directors, with at least 50% anticipated to be paid in stock. If paid in stock, it will be at the respective price per share of the completed round. For business development, you will also be eligible for payment of a bonus of 1.0% cash received for partnerships directly originated by you. After 24 months, the Compensation Committee of the BOD anticipates determining your new incentive/bonus pay for financings and business development. All payments and other amounts contemplated to be payable by this letter will be reduced by all tax or other amounts required to be withheld under applicable law.

Stock Options: Subject to approval by the Board of Directors (or an appropriate Committee appointed by the Board of Directors), and pursuant to a written stock option agreement entered into by and between you and the Company (the “Option Agreement”). The Company will grant you an option to purchase 230,000 shares of Abpro Common Stock (the “Option”) in accordance with the terms of the Option Agreement once you are working full time.

Benefits/Relocation: You may participate in any and all of the benefit programs once you are working full time, including paid time off and holidays, that the Company establishes and makes available to its employees from time to time, provided you are eligible under (and subject to all provisions of) the plan documents governing these programs. Abpro will reimburse you for up to $12.SK for relocation expenses via receipts submitted. Abpro may also advance you funds of up to $ 18.5K for additional relocation expenses upon mutual consent as an advance against a future bonus.

Our offer is contingent upon (1) the successful completion of acceptable reference and background checks; (2) your execution of an Abpro At-Will Employment, Confidential Information, Invention Assignment, Non-compete and Arbitration Agreement (the “Confidentiality Agreement”). a copy of which is enclosed with this letter; and (3) submission of an I-9 Employment Eligibility Verification Form acceptable to the Company within three (3) days of your date of employment. You must be prepared to offer proof of your employability in the United States in accordance with the requirements listed on the I-9 Form within the first three (3) days of employment.
