   1.                                                   Please revise this risk
factor to disclose that there is also a risk that the exclusive forum
                                                        provision in your
amended and restated memorandum and articles of association may

2.       We note your new disclosure that you have agreed to engage Cowen and
Company, LLC,
         an underwriter of this offering, to provide financial advisory and
placement
         agent services in connection with your initial business combination.
Please include
         additional disclosure here, as well as in your risk factor disclosure
and summary section,
         to address the following:

                The cost of these services, if known;

                Whether or not the fees are conditioned on the consummation of
a business
              combination; and

                Potential conflicts of interest that Cowen and Company, LLC may
have in providing
              these services (i) given the deferred underwriting compensation
discussed elsewhere
              in the prospectus and (ii) given their affiliate, CB
Co-Investment LLC, currently
              owns a substantial amount of your founder shares that would
become worthless
              without an initial business combination.

         For guidance, refer to CF Disclosure Guidance: Topic No. 11.
