Explanation of Responses:

( 1 )Each share that Dynamics Sponsor LLC, a Delaware limited liability company (the "Sponsor"), held as record holder of Class B common stock, par value $0.0001, automatically converted into one share of Class A common stock, par value $0.0001, at the closing of the Issuer's initial business combination on June 8, 2022, and, pursuant to the Issuer's amended certificate of incorporation which came into effect on such date, shares of Class A common stock became shares of common stock (without class designation), par value $0.0001, of the Issuer at such time. The shares of Class B common stock had no expiration date. ( 2 )Upon the consummation of the business combination described in footnote 1, the Sponsor distributed 123,252 shares of common stock of the Issuer to David Epstein. ( 3 )Prior to the distribution described in footnote 2, the Sponsor was the record holder of these shares. The Sponsor is governed by a board of managers consisting of Omid Farokhzad and Mostafa Ronaghi who held an economic interest therein. Any action by the Sponsor with respect to Issuer or the shares reported above, including voting and dispositive decisions, requires unanimous approval of the managers. The shares reported were attributable to Mr. Epstein's equity ownership interest of the Sponsor.
