You will initially earn a monthly base salary of $8333.33 annualized at $100,000, which shall be paid in accordance with Amyris’ regular payroll schedule. Upon Amyris’ first equity funding event or corporate partnership to which you contribute materially and which is worth at least $4,000,000 your annualized salary will be increased by $50,000 to $150,000. Further, this pay raise will be retroactive to your initial date of employment. For funding events of less than $4,000,000 and more than $1,000,000, the aforementioned raise will be a based on the following formula: $50,000*(Funding-1,000,000)/3,000,000.

Benefits.

You will be eligible to participate in the employee benefits plans, including paid time off, that are generally made available to the employees of Amyris, as those benefits become available. At this time, Amyris can offer you three (3) weeks of vacation and the payment of your California Bar Dues. Further, Amyris will contribute to you MCLE fees in accordance with our standard budget for employee attendance of conferences (currently estimated at $1500/year). Because Amyris is newly-formed, we are working diligently to put in place a full range of benefits as soon as possible.

Equity.

Notwithstanding clause (i) of the preceding paragraph, if, at any time during the initial twelve (12) months of your employment with Amyris, there is an Involuntary Termination of your

employment, a number of Option Shares equal to (x) 1/48 of the Option Shares, multiplied by (y) the number of months you were employed by Amyris prior to the effective date of such Involuntary Termination (pro-rated for any month(s) of partial employment) shall accelerate and become immediately vested. For purposes of this offer letter, an “Involuntary Termination” shall mean the termination of your employment with Amyris for one or more of the following reasons:
