Explanation of Responses:
1. Each share of the Series A, Series C, Series D, Series E-1, Series E-2 and Series F Preferred Stock converted into Common Stock immediately prior to the completion of the Issuer's initial public offering (the "Offering") pursuant to its terms.
2. The Convertible Notes automatically converted into Common Stock immediately prior to the closing of the Offering. The conversion price is the lower of (a) 80% of the Offering price per share and (b) the valuation of the Issuer immediately prior to the closing of the Offering divided by the number of fully diluted shares of capital stock (on an as-converted basis) outstanding immediately prior to Offering, excluding the Convertible Notes.
3. This transaction occurred prior to the Issuer's registration of a class of equity securities under Section 12 of the Securities Exchange Act of 1934, as amended, in connection with the Offering, and is reported herein pursuant to Rule 16a-2(a).
4. The stock option will vest as to 25% of the underlying shares on May 7, 2027, and will vest thereafter in 36 substantially equal monthly installments.
5. The warrants are currently exercisable. In connection with the Offering, the warrants were exercised according to the terms of the applicable warrant agreement. The warrants have a net exercise provision under which the Reporting Person may, in lieu of payment of the exercise price in cash, surrender the warrants and receive a net amount of shares based on the fair market value of the shares at the time of exercise of the warrants after deduction of the aggregate exercise price.
