Explanation of Responses:

( 1 )Each share of Series D Preferred Stock, Series F Preferred Stock, Series E-1 Preferred Stock and Series E-2 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 securities are held by GPG JCT, LLC ("JCT"). ( 3 )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. ( 4 )The securities are held by GPG MTI 22, LLC ("MTI 22"). ( 5 )The securities are held by GPG MTI 25, LLC ("MTI 25"). ( 6 )The securities are held by GPG MTI 3-17 Investment, LLC ("MTI 3-17"). ( 7 )Common stock issued upon exercise of warrant to purchase Series D Preferred Stock. The warrants are currently exercisable and have an exercise price of $4.207 per share. Unless exercised earlier, the warrants will expire on May 25, 2033. ( 8 )The securities are held by GPG PHL, LLC ("PHL"). ( 9 )The securities are held by GPG RM Investment, LLC ("RM"). ( 10 )Green Park & Golf Ventures II, LLC ("GPG Ventures II") is the managing member of each of JCT, MTI 22, MTI 25, MTI 3-17, PHL, and RM. Clay M. Heighten, MD, Carl D. Soderstrom and Gilbert G. Garcia II are managers of GPG Ventures II and share voting and dispositive power with respect to the shares held by each of JCT, MTI 22, MTI 25, MTI 3-17, PHL, and RM., and as a result may be deemed to beneficially own such securities. ( 11 )RM paid the exercise price on a cashless basis, resulting in the Issuer's withholding of 6,731 shares of Common Stock to pay the exercise price and issuing to the reporting person the remaining 159 shares of Common Stock.
