Explanation of Responses:

( 1 )QH Hungary Holdings Limited ("QH Hungary") is a wholly owned subsidiary of the Reporting Person. On October 13, 2023, (a) 14,432 shares of Common Stock of the Issuer ("Shares") beneficially owned by the Reporting Person but held in the name of Citibank N.A. pursuant to an escrow agreement in order to secure the Reporting Person's indemnification obligations related to the Issuer's acquisition of Global Houghton Ltd. were released from escrow to the Issuer in order to satisfy such indemnification obligations and (b) 17,737 Shares were released from escrow to the Reporting Person as such Shares were no longer needed to secure indemnification obligations. ( 2 )Following such escrow release, the Reporting Person continues to (i) directly beneficially own 22,754 Shares, 5,017 of which are held in the name of Citibank N.A. pursuant to the escrow agreement described above and (ii) indirectly beneficially own 3,992,377 Shares, which are owned by QH Hungary, for a total direct and indirect beneficial ownership of 4,015,131 Shares by the Reporting Person. ( 3 )This Amendment (this "Amendment") to the Form 4 originally filed on October 17, 2023 is being filed to list the total direct and indirect beneficial ownership of 4,015,131 Shares by the Reporting Person in Sections 5 and 6 of Table I instead of only the indirect beneficial ownership of the Shares that are held by QH Hungary, which indirect beneficial ownership was incorrectly listed as 3,977,945 and which instead should have been 3,992,377. This Amendment also supplements and corrects the share numbers listed in footnote 1 above.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
