   1.                                                   We note your disclosure
that your sponsor may extend up to 21 months the deadline to
                                                        complete an initial
business combination by purchasing additional warrants at any time
                                                        after the closing of
the offering and prior to the consummation of your initial business
                                                        combination. Please
disclose on the cover page, consistent with your risk factor beginning
                                                        on page 63, that this
structure is unlike the structure of similar blank check companies,
                                                        which you indicate
generally are only permitted to extend the time period in connection
                                                        with amendments to the
certificate of incorporation, and that stockholders will not be
                                                        entitled to vote on or
redeem their shares in connection with such extension.

2.       With a view toward disclosure, please tell us whether your sponsor is,
is controlled by, or
         has substantial ties with a non-U.S. person. If so, also 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 U.S. 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. Disclose that
         as a result, the pool of potential targets with which you could
complete an initial business
         combination may be limited. 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.
        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.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
