Risk Factors, page 27

2.       Please clarify the meaning of non-transgenic gene-edited agricultural
products.
3.       Please disclose the material risks to unaffiliated investors presented
by taking the
         company public through a merger rather than an underwritten offering.
These risks could
         include the absence of due diligence conducted by an underwriter that
would be subject to
         liability for any material misstatements or omissions in a
registration statement.
The extent to which the COVID-19 pandemic and resulting deterioration of
worldwide economic
conditions adversely impact our business, page 33

4.       Please revise this risk factor and your disclosure under Management's
Discussion and
         Analysis of Financial Condition and Results of Operations to discuss
any material impact
         COVID-19 has had on Benson Hill's results of operations and financial
condition or

6.       Revise your disclosure to show the potential impact of redemptions on
the per share value
         of the shares owned by non-redeeming shareholders by including a
sensitivity analysis
         showing a range of redemption scenarios, including minimum, maximum
and interim
         redemption levels.
7.       Please revise to disclose all possible sources and extent of dilution
that shareholders who
         elect not to redeem their shares may experience in connection with the
business
         combination. Provide disclosure of the impact of each significant
source of dilution,
         including the amount of equity held by founders, and convertible
securities, including
         warrants retained by redeeming shareholders, at each of the redemption
levels detailed in
         your sensitivity analysis, including any needed assumptions.
8.       Quantify the value of warrants, based on recent trading prices, that
may be retained by
         redeeming stockholders assuming maximum redemptions and identify any
material
         resulting risks.
9.       It appears that underwriting fees remain constant and are not adjusted
based on
         redemptions. Revise your disclosure to disclose the effective
underwriting fee on a
         percentage basis for shares at each redemption level presented in your
sensitivity analysis
         related to dilution.

possibilities
         between no redemption and redemption of 40,250,000 Class A shares in
exchange for
         $402.5 million, which you describe as the maximum redemption scenario.
Tell us the
         extent to which you have received indications from shareholders
regarding their intentions
         to redeem or retain their shares that would make any scenario within
this range more
         likely to occur; and if you have formulated an expectation based on
such indications or
         other information, describe that process and your consideration to
providing an additional
         corresponding pro forma scenario.
12.      Please modify your pro forma presentation such that it is apparent
that certain transaction
         adjustments listed under the column heading, No Redemption Scenario
are also applicable
         to the Maximum Redemption Scenario. In this regard, we note
Transaction Adjustments
         (c) through (h) are listed under the title, No Redemption Scenario
Transaction
         Adjustments on page 65; however, all but Transaction adjustment (g)
are applicable to

         million to Additional paid in capital. Please disclose why you have
reclassified this
         liability amount to equity and what the remaining warrant liability in
the amount of $12.3
         represents.
14.      We note in connection with the merger you will enter into an earn out
arrangement under
         which shares will be placed in escrow and may be released to certain

share price milestones
         within a three year period. In addition, we note earn out awards with
a value equivalent to
         2,037,320 shares of New Benson Hill common stock will be granted under

expand your pro
