Richard J. Deranleau

Dear Richard:

eASIC Corporation (“eASIC” or the “Company”) is pleased to formally offer you a full time position as Chief Financial Officer of the Company. You will report to me, and you will be responsible for duties commensurate with this position, provided that the Company may change your position and duties from time to time in its discretion. Throughout the term of your employment, you will devote on a full time basis such business time and energies to the business and affairs of the Company as needed to carry out your duties and responsibilities. Your office will be in our corporate headquarters facility in Santa Clara, California.

Compensation:

Your annual base salary will be $245,000 less payroll deductions and all required withholdings.

You are eligible to receive additional cash compensation (the “2014 Management Bonus Plan”) based on metrics tied to the Company’s overall performance as determined by the Board. The target bonus compensation you may receive under the 2014 Management Bonus Plan shall be 40% of your base salary. Your 2014 bonus opportunity will be pro-rated based on the number of days in which you are employed with eASIC in 2014. You must remain employed through the bonus payment dates in order to earn such bonus and for such bonuses in subsequent years, and your bonuses are not guaranteed. Notwithstanding the foregoing, your 40% bonus will be guaranteed solely from the period of your start date through 3 months following the lock-up expiration of an initial public offering of the Company’s stock or the closing of the sale of the majority or greater of the Company’s stock, whichever is earlier. During this period, your bonus will be paid on a quarterly basis in arrears and your first payment will be pro rated based on the number of days in which you are employed with eASIC during that quarter.

You are also eligible to participate in the Company’s health benefits, vacation and holiday pay, and other employee benefits, in accordance with the Company’s employee policies as developed, adopted and modified from time to time. The Company reserves the right to modify or cancel such benefits at any time.
