(“LanzaTech” or “Company”) is providing me with a Sign-On/Retention Incentive in the amount of $375,000 (the “Advance”) associated with my acceptance of employment and my continued employment with LanzaTech for twenty-four (24) months after my start of employment. While $125,000 of the Advance will be advanced to me on the first regularly scheduled pay date after my employment start with LanzaTech and the remaining $250,000 will be advanced in two equal installments after six (6) months and twelve (12) months of employment, respectively, I understand and agree that I will earn the full Advance only after I remain employed by LanzaTech for twenty-four (24) months and that it will be earned over the course of those twenty-four (24) months according to the below schedule. Accordingly, if I resign or my employment is terminated by LanzaTech for any reason before I complete twenty-four (24) months of employment, other than in the event of a Qualifying Termination (as defined in my employment agreement), I will be responsible for repaying to LanzaTech all or part of the Advance previously paid to me prior to my termination date according to the following schedule: Repayment of 100% of the Advance if employed for less than 6 months Repayment of 75% of the Advance if employed for 6 months or longer and less than 12 months Repayment of 50% of the Advance if employed for 12 months or longer and less than 18 months Repayment of 25% of the Advance if employed for 18 months or longer and less than 24 months If I terminate before any portion of the Advance is scheduled to be paid to me, I acknowledge and agree that LanzaTech shall not have an obligation to pay me such unpaid portion. I agree that, to the extent permitted by applicable law, LanzaTech may deduct any repayable Advance from my final wages, bonuses earned but unpaid, severance pay, or other compensation due to me upon termination of employment up to the full amount owed. I agree to pay any balance of the repayable amount within thirty (30) days of the date of my termination. If I do not pay the repayable Advance in accordance with this paragraph, I agree to pay any and all collection fees, interest, and attorneys’ fees that LanzaTech incurs in collection or settlement of the Advance. I also acknowledge that the Advance is not part of my base salary calculation but is considered taxable income when paid. I understand that my employment with LanzaTech is considered at-will, meaning that either LanzaTech or I may terminate this employment relationship at any time with or without cause or notice.
