Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Employee stock options (right-to-buy) ("Options") granted pursuant to Issuer's 2018 Equity Incentive Plan (the "Plan"), and the related award agreement entered into pursuant thereto, in accordance with the terms of Reporting Person's employment agreement dated September 12, 2018 (the "Employment Agreement").
(2)	Effective date of grant is September 12, 2018.
(3)	Options vest over three years in equal installments on each of the first three anniversaries of the effective date of grant, provided Reporting Person continues in employment with Issuer through each vesting date. Only vested options are exercisable.
(4)	Restricted Stock Units ("RSUs") granted pursuant to the Plan and the related award agreement entered into pursuant thereto, in accordance with the terms of the Employment Agreement.
(5)	RSUs vest over three years on the anniversary of the effective date of grant, provided Reporting Person continues in employment with Issuer through each vesting date, as follows: 15,000 RSUs vest on the first anniversary and 45,000 shares vest on each of the second and third anniversaries.
(6)	Not applicable.
(7)	Performance-based restricted stock units ("PRSUs") granted pursuant to the Plan and the related award agreement entered into pursuant thereto, in accordance with the terms of the Employment Agreement.
(8)	This is a target only. Number of PRSUs is tied to satisfaction of certain performance criteria (other than the price of Issuer's commons stock), as defined in the Employment Agreement. Reporting Person may acquire shares of Issuer's common stock to the extent that the performance targets are achieved as of the end of certain performance periods ending June 30, 2019, June 30, 2020 and June 30, 2021. The actual number of shares ultimately deliverable ranges from 0 to 131,250 shares (subject to any subsequent stock split and the like). PRSUs earned, if any, will vest in installments on specific dates over three years subject to certain conditions.
