Offer Letter between Tom vonReichbauer and Sunrun Inc., dated as of April 17, 2020

Sunrun Inc. (the “Company”) is pleased to offer you the exempt position of Chief Financial Officer (“CFO”), reporting directly to our chief executive officer, Lynn Jurich. As CFO, you will have all the duties customarily granted to such a position including those in the Company bylaws. This position is located in San Francisco, CA. Your first day of employment (“Start Date”) would be approximately May 4, 2020. This date is subject to change based upon agreement between you and the Company. Please note that as Sunrun is a quickly growing and evolving organization, the Company may periodically change your duties and work location, subject to the terms of this letter Agreement. If there is any conflict or disagreement with the terms of any other agreement you have with the Company, the terms of this letter Agreement shall prevail.

If you decide to join us, your annual salary will be $440,000.00 less applicable tax withholdings. You will be paid bi-weekly.

You will be eligible to participate in the Company’s Amended and Restated Executive Incentive Compensation Plan (EICP), with a target of 80% of your base salary. Incentives are discretionary and depend on both Company performance and your individual performance. All EICP incentives are subject to the terms and conditions of the plan, which will be provided to you separately. Incentive targets are pro-rated for the year in which you are hired and you must begin employment before October 1, 2020 to be eligible to earn the 2020 EICP. In addition, you will be subject to the terms of the Company’s Policy for Recoupment of Incentive Compensation. Details will be provided to you separately along with such policy.

In addition to the terms outlined in this offer, the Company agrees to pay you a one-time sign on bonus of $100,000.00 less applicable tax withholdings (the “Sign On Bonus”). By accepting this offer of employment, however, in the event that you voluntarily resign your employment (except if you resign for Good Reason (as defined in the Key Employee Change in Control and Severance Plan) or you are terminated for Cause within twenty-four months of the Start Date of your new position, you agree to reimburse Sunrun a pro-rata portion of the sign on bonus within 30 days of your termination date and/or sign a contemporaneous agreement at the time of your separation allowing Sunrun to set-off the amount from your final pay. For clarity, to determine the portion of the sign on bonus you owe, we will divide the number of weeks of service you completed with the Company by 104 and subtract this figure from 1.0. For example, if you resign your employment and have completed 80 weeks of service, you will owe 23% of your one-time bonus to the company as repayment (80/104 = 0.769. 1.0 - 0.769 = 0.23, or 23% of $100,000.00 owed to the Company). If you die or become disabled and unable to perform the duties of CFO, the repayment of the sign on bonus shall be waived.

Upon commencement of employment, the Company will recommend to the Board of Directors that you be granted an initial equity award valued at $4,500,000 in the form of 50% in Options and 50% in Restricted Stock Units (RSUs). The number of shares underlying such RSUs will be determined by dividing $2,250,000 by the average trailing 45 calendar-day closing price of the Company’s stock, ending on the day prior to your Start Date. The grant date shall be your Start Date or as soon as reasonably practicable thereafter, but no more than 14 calendar days after your Start Date. The number of stock options will be determined based on the then current Black Scholes value of the Company stock on your Start Date.

The RSUs will vest over four years, commencing on the date approved by the Board of Directors (the “Vesting Commencement Date”), with twenty-five percent (25%) of such units vesting on the one-year anniversary of your Vesting Commencement Date, and the remaining units vesting in equal quarterly installments thereafter (e.g., every three months following the one-year anniversary of your Vesting Commencement Date), contingent upon your continuous employment at the Company through each such date. The RSUs will be subject to the terms and conditions applicable to RSUs awarded under the Company’s 2015 Equity Incentive Plan (the “2015 Plan”), as described in the 2015 Plan and the applicable 2015 RSU Award Agreement.

The shares subject to the Option will vest over four years, commencing on the Vesting Commencement Date, with twenty-five percent (25%) of such shares vesting on the one-year anniversary of your Vesting Commencement Date, and the remaining shares vesting in equal monthly installments thereafter contingent upon your continuous employment at the Company through each such date. The shares subject to the Option will be subject to the terms and conditions applicable to shares awarded under the Company’s 2015 Equity Incentive Plan, as described in the 2015 Plan and the applicable 2015 Option Award Agreement.

As a regular full-time employee of Sunrun Inc., you will be eligible to participate in a number of Company-sponsored benefits beginning the first of the month following your Start Date.
