Explanation of responses 3 footnotes

Footnote F1

Reflects the 452,500 Class A ordinary shares, par value $0.0001 per share ("Class A Ordinary Shares"), of Market Technology Acquisition Corp (the "Issuer") included in the 452,500 private placement units ("Private Placement Units") of the Issuer purchased by Market Technology Acquisition Sponsor LLC (the "Sponsor") at the time of the closing of the Issuer's initial public offering ("IPO"). Each Private Placement Unit was purchased for $10 per unit and consists of one Class A Ordinary Share and one-half (1/2) of one redeemable warrant.

Footnote F2

Reflects 833,334 of the 7,666,667 Class B ordinary shares, par value $0.0001 per share ("Class B Ordinary Shares"), previously acquired by the Sponsor. The 833,334 Class B Ordinary Shares were forfeited by the Sponsor as a result of the IPO underwriters exercising some but not all of their over-allotment option. As a result, the Sponsor holds 6,833,333 Class B Ordinary Shares, which will automatically convert on a one-for-one basis into Class A Ordinary Shares at the time of the Issuer's initial business combination, or at any time prior to the Issuer's initial business combination at the option of the holder, subject to adjustment as described under the heading "Description of Securities - Founder Shares" in the Issuer's registration statement on Form S-1 (File No. 333-296835), relating to its IPO.
