        <footnote id="F1">Includes securities underlying the 24,000 private placement units of the Issuer purchased by Consonance Life Sciences, LLC (the &quot;Sponsor&quot;) for $10.00 per private placement unit. The private placement units were purchased in a private placement upon the exercise in full of the over-allotment option granted to the underwriters to purchase additional shares in the Issuer's initial public offering. Each unit consists of one Class A ordinary share and one-third of one warrant, with each whole warrant entitling the holder to purchase one Class A ordinary share at $11.50 per share.</footnote>
        <footnote id="F2">The Sponsor is the record holder of the shares and warrants reported herein. The Sponsor is governed by a board of managers consisting of Mitchell J. Blutt, Benny Soffer and Kevin Livingston. As such, Mitchell J. Blutt, Benny Soffer and Kevin Livingston have voting and investment discretion over the shares held by the Sponsor and may be deemed to have shared beneficial ownership of the shares held by the Sponsor. Each of Mitchell J. Blutt, Benny Soffer and Kevin Livingston disclaims beneficial ownership of the reported shares other than to the extent of any pecuniary interest he may have therein, directly or indirectly.</footnote>
        <footnote id="F3">The warrants will become exercisable on the later of (a) 30 days after the completion of the Issuer's initial business combination or (b) 12 months from the closing of the Issuer's initial public offering.</footnote>
