Dear Cameron,

I am pleased to offer you a position with Transphorm, Inc. (the “Company”) as CFO commencing on or before November 2, 2015. If you decide to join the Company, you will report to Mario Rivas, CEO, and you will receive a rate of $8,653.84 bi-weekly ($225,000.00 annual equivalent) less applicable withholding, which will be paid in accordance with the Company’s normal payroll procedures. This is a full-time, exempt position.

As a full-time exempt Company employee, you will also be eligible to accrue 29 days of paid time off annually, subject to the Company’s PTO policy, and certain standard employee benefits, as such may be in effect from time to time and subject to the terms and conditions of the Company’s benefits plans. You should note that the Company may modify salaries and benefits from time to time in its discretion as it deems necessary.

If you join the Company and subject to your continued employment on such date, it will be recommended at the first meeting of the Company’s Board of Directors following your start date that the Company grant you an option to purchase 750,000 shares of the Company’s Common Stock, pursuant to the Company’s 2015 Equity Incentive Plan (the “Plan”), at a price per share at least equal to the fair market value per share of the Common Stock on the date of grant, as determined by the Company’s Board of Directors. Twenty-five percent (25%) of the shares subject to the option shall vest twelve (12) months after the date your vesting begins, subject to your continuing employment with the Company, no shares shall vest before such date. The remaining shares shall vest monthly over the next thirty-six (36) months in equal monthly amounts subject to your continuing employment with the Company. This option grant shall be subject to the terms and conditions of the Plan and related Stock Option Agreement, including vesting requirements. No right to any stock is earned or accrued until such time that vesting occurs, nor does the grant confer any right to continue vesting or employment.

This job offer is contingent upon a clearance of a background investigation and reference check, in accordance with applicable law. This investigation and reference check may include a consumer report, as defined by the Fair Credit Reporting Act (“FCRA”), 15 U.S.C. 1681a, and/or an investigative consumer report, as defined by FCRA, 15 U.S.C. 1681a, and California Civil Code 1786.2(c).

Authorization for important disclosures and a written authorization form. For purposes of federal immigration law, you will be required to provide to the Company documentary evidence of your identity and eligibility for employment in the United States.

You should be aware that your employment with the Company is for no specified period and constitutes at-will employment. As a result, you are free to resign at any time, for any reason or for no reason. Similarly, the Company is free to conclude its employment relationship with you at any time, with or without cause, and with or without notice. As a condition to accepting our employment offer, you shall disclose to the Company any and all agreements relating to your prior employment that may affect your eligibility to be employed by the Company or limit the manner in which you may be employed.

Similarly, you agree not to bring any third party confidential information to the Company, including that of your former employer, and that in performing your duties for the Company you will not in any way utilize any such information in performing your duties for the Company.

As a Company employee, you will be required to sign and comply with an At-Will Employment, Confidential Information, Invention Assignment and Arbitration Information Agreement (“Employee Confidentiality Agreement”) which requires, among other provisions, the assignment of patent rights to any invention made during your employment at the Company and non-disclosure of proprietary information. Moreover, in the event of any dispute or claim relating to or arising out of our employment relationship, you and the Company agree under the Employee Confidentiality Agreement to an arbitration in which (i) you are waiving any and all rights to a jury trial but all court remedies will be available in arbitration, (ii) we agree that all disputes between you and the Company shall be fully and finally resolved by binding arbitration, (iii) all disputes shall be resolved by a neutral arbitrator who shall issue a written opinion, (iv) the arbitration shall provide for adequate discovery, and (v) the Company shall pay all the arbitration fees, except an amount equal to the filing fees you would have paid had you filed a complaint in a court of law.
