You are eligible for a sign-on bonus of $45,000 ("Sign-On Bonus") to be paid on or before March 15, 2018. In the event you voluntarily resign from the Company within one year of the payment date of the Sign-On Bonus, the Sign-On Bonus must be refunded to the Company and you authorize the Company to deduct this obligation insofar as possible, from any salary, wages, accrued vacation, bonus or other payments or employee benefits to which you may be entitled, or business expense reimbursement amounts that may be due to you. You agree that you remain liable for any amount that is not withheld from your wages. By signing this offer letter, you accept the terms of this agreement.

The severance payments will include an amount equal to one times your annual base salary in effect prior to the date employment is terminated and an amount equal to a pro rata portion of the aggregate bonus you would have been entitled to receive with respect to the fiscal year of termination had employment not been terminated.
