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)	On February 12, 2026, the reporting person exercised options to purchase 31,710 shares of the issuer's common stock for $1.93 per share, 120,248 shares of the issuer's common stock for $1.68 per share, 78,249 shares of the issuer's common stock for $2.69 per share, and 20,969 shares of the issuer's common stock for $3.09 per share. The reporting person paid the exercise price on a cashless basis, resulting in the issuer withholding 41,105 of the option shares to pay the exercise price and issuing to the reporting person 210,071 shares.
(2)	The option grant was approved by a committee of the issuer's Board of Directors on February 21, 2017, subject to shareholder approval of an amendment to the issuer's 2016 Equity Incentive Plan to increase the maximum number of shares that may be granted to any one participant during a one-year period to 500,000. The issuer's shareholders approved the amendment on June 15, 2017. The option vested in 36 monthly installments beginning March 21, 2017, except that all vesting attributable to periods prior to June 15, 2017 was deemed to have occurred on June 15, 2017.
(3)	The option vested 25% on the first anniversary of the grant date and thereafter in 36 equal monthly installments.
