       Risks Related to JATT and the Business Combination, page 88

   1.                                                   With a view toward
disclosure, please tell us whether your Sponsor is, is controlled by,
                                                        has any members who
are, or has substantial ties with, a non-U.S. person. Please also tell
                                                        us whether anyone or
any entity associated with or otherwise involved in the transaction,
                                                        is, is controlled by,
or has substantial ties with a non-U.S. person. If so, please revise your
                                                        filing to include risk
factor disclosure that addresses how this fact could impact your
                                                        ability to complete
your initial business combination. For instance, discuss the risk to
                                                        investors that you may
not be able to complete an initial business combination with a

      target company should the transaction be subject to review by a U.S.
government entity,
      such as the Committee on Foreign Investment in the United States (CFIUS),
or ultimately
      prohibited. Further, disclose that the time necessary for government
review of the
      transaction or a decision to prohibit the transaction could prevent you
from completing an
      initial business combination and require you to liquidate. Disclose the
consequences of
      liquidation to investors, such as the losses of the investment
opportunity in a target
      company, any price appreciation in the combined company, and the
warrants, which
      would expire worthless.
