Equity Awards.

Initial Grant

Concurrent with the commencement of your employment with the Company, you will be granted an option to purchase 250,000 shares of common stock of the Company (“Company Common Stock”) under the terms and conditions of a Non-Qualified Stock Option Agreement. The Option shall vest and become exercisable in accordance with the schedule below:

· 25% of the shares subject to the Option will be fully vested and exercisable effective as of February 11, 2016 (the “Initial Vesting Date”), subject to your continued service through the Initial Vesting Date, and;

· 75% of the shares subject to the Option will vest and become exercisable in 36 equal monthly installments following the Initial Vesting Date, with the first such monthly vesting date taking place on February 29, 2016 and subsequent vesting dates on the last day of the next 35 months thereafter (with the last vesting date on January 31, 2019), subject to your continued service through the applicable vesting date.

IPO Grant

In connection with, and subject to the completion of, the Company’s IPO, if you remain employed until the completion of the IPO then, subject to the approval of the Compensation Committee, you will be granted an option to purchase Company Common Stock with a target cash value of approximately $808,000 (the “IPO Option Award”) under the Company’s 2015 Omnibus Equity Incentive Plan (the “Equity Plan”). The number of shares subject to the IPO Option Award will be determined by dividing the target value allocated to the IPO Option Award by the Black-Scholes value of a share of Company Common Stock on the date of grant.  The exercise price for the IPO Option will be the initial public offering price per share of Company Common Stock.  The IPO Option Award will be evidenced by, and subject to the provisions of, a stock option agreement in a form approved by the Compensation Committee for use with the Equity Plan.
