       Preliminary Proxy Statement on Schedule 14A

       General

   1.                                                   We note that you are
seeking to extend your termination date beyond July 2, 2024,
                                                        36 months after the
consummation of your initial public offering. We also note that you
                                                        are listed on The
Nasdaq Capital Market and that Nasdaq IM-5101-2 requires that a
                                                        special purpose
acquisition company complete one or more business combinations within
                                                        36 months of the
effectiveness of its IPO registration statement. Please revise to explain
                                                        that the proposal to
extend your termination deadline beyond July 2, 2024, does not
                                                        comply with this rule,
or advise, and to disclose the risks of your non-compliance with this
                                                        rule, including that
your securities may be subject to suspension and delisting from The
                                                        Nasdaq Capital Market,
and the consequences of any such suspension or delisting.
               We remind you that the company and its management are
responsible for the accuracy
       and adequacy of their disclosures, notwithstanding any review, comments,
action or absence of
       action by the staff.
