       Questions and Answers About the Business Combination and the Special
Meeting, page 12

   1.                                                   We note your response
to prior comment 23 and your disclosure on page 292 indicating
                                                        that NKMAX would own a
majority of your common stock following the Business
                                                        Combination in the
maximum redemption scenario. Please revise to add a
                                                        Q&A reflecting the fact
that NKMAX could own a majority of your common stock
                                                        following the merger,
including if redemptions exceed the maximum redemption scenario
                                                        and the parties elect
to close the Business Combination, and that you would therefore be a
                                                        "controlled company"
under NYSE rules, if true. In your Q&A and Summary disclosure,
                                                        discuss (i) the
consequences of potentially becoming a "controlled company" to your
                                                        current stockholders,
(ii) NKMAX's current intentions with respect to its shares of New

         NKGen common stock assuming the Business Combination is consummated
and (iii)
         whether New NKGen will be contractually obligated to file a
registration statement for the
         resale of its shares held by NKMAX following the Business Combination.

2.       We note your response to prior comment 3 and revised disclosure,
including your use of
         the term "Activity" and re-issue in part. Please limit your discussion
of the performance
         of NKGen's SNK cells to objective results from NKGen's preclinical
tests and clinical
         trials. Please tell us whether the term "Activity" is a commonly-used
defined term in
         clinical trials involving the use of NK cells. To the extent this
defined term is not used or
         defined as such by NKGen in its daily business, or is not commonly
used or understood in
         NKGen's industry, please remove it from the prospectus.
What will New NKGen's liquidity position be following the Closing?, page 19

3.       Please revise this Q&A to reflect your disclosure on page 76
indicating that New NKGen
         will be required to maintain a minimum cash balance of $15.0 million
with East West
         Bank after the completion of the Business Combination and the
consequences of
         stockholders if you fail to meet this requirement.

         Please also revise to reflect your disclosure that the revolving line
of credit with East West
         Bank is secured by all of NKGen's assets. Please disclose whether New
NKGen's failure
         to maintain a cash balance of at least $15.0 million immediately
following the Business
         Combination and payment of transaction expenses would constitute an
event of default
         under the revolving line of credit that would allow East West Bank to
proceed against
         New NKGen's assets.

your disclosure
         on page 239 indicates that your collaboration with Affimed has been
discontinued. Please
         remove AFM24 from your pipeline table or advise.
