BENSON HILL, INC.1


STOCK
PURCHASE WARRANT


 


THIS CERTIFIES THAT for value
received, subject to the terms and conditions hereinafter set forth, [  ], or permitted assigns (the “Holder”), is entitled
to purchase shares of the capital stock of Benson Hill, Inc., a Delaware corporation (the “Company”), as determined
in accordance with this Warrant, upon presentation of this Warrant and payment of the Exercise Price (as defined below) for the shares
of capital stock purchased at the principal office of the Company or at such other place as shall have been designated by the Company.


 


This Warrant is subject to the following provisions:


 


		1.	Class, Number, and Exercise Price of Shares of Capital Stock.



 


(a)           This
Warrant may be exercised for Two Hundred Twenty-Five Thousand (225,000) shares of the Company’s Common Stock, $0.001 par value per
share (the “Common Stock”) (the “Warrant Shares”), subject to possible adjustment as provided herein.


 


(b)           The
purchase price for each Warrant Share purchased upon exercise of this Warrant shall be Ten Dollars ($10.00) (the “Exercise Price”),
subject to possible adjustment as provided herein, payable in lawful money of the United States of America in full upon exercise of this
Warrant.


 


		2.	Exercise of Warrant.



 


(a)           This
Warrant may be exercised, in whole or in part, by the surrender of this Warrant to the Company (with the notice of exercise form attached
hereto as Exhibit A duly executed), at the principal office of the Company at any time during the Exercise Period.


 


(b)           The
 “Exercise Period” is that period beginning on the date hereof, and continuing up to and including 11:59.59 p.m., St.
Louis Missouri time, on June 30, 2024.


 





 






 1          This warrant was issued pursuant to Section 4.3(b) of that certain Warrant to Acquire Securities of Benson Hill, Inc., dated as of September 8, 2021 (the “Original Warrant”) as the Pre-Merger Warrant (as defined in the Original Warrant). For the avoidance of doubt, this warrant was issued prior to closing of transactions contemplated by the Merger Agreement (as defined in the Original Warrant).




 






     


     


    

 


		3.	Adjustment of Exercise Price and Number of Shares.



 


(a)           The
Exercise Price and Warrant Shares shall be subject to the following adjustments:


 


(i)            If,
at any time during the Exercise Period, the Company shall declare and pay on the Company’s Common Stock a dividend or other distribution
payable in shares of Common Stock, the Warrant Shares shall be proportionately increased so that the Holder shall be entitled to receive
(upon exercise of this Warrant) the number of shares of Common Stock which the Holder would have owned or been entitled to receive after
the declaration and payment of such dividend or other distribution if the Warrant had been exercised immediately prior to the record date
for the determination of stockholders entitled to receive such dividend or other distribution, and the Exercise Price shall be proportionately
decreased so that the aggregate Exercise Price payable upon exercise in full of this Warrant shall remain the same.


 


(ii)            If,
at any time during the Exercise Period, the Company shall subdivide the outstanding shares of the Company’s Common Stock into a
greater number of shares, or combine the outstanding shares of Common Stock into a lesser number of shares, or issue by reclassification
of its shares of Common Stock any shares of the Company’s Common Stock, the Warrant Shares shall be proportionately adjusted so
that the Holder shall be entitled to receive (upon exercise of this Warrant) the number of shares of Common Stock or such other shares
which the Holder would have owned or been entitled to receive after the happening of any of the events described above if the Warrant
had been exercised immediately prior to the happening of such event on the day upon which such subdivision, combination or reclassification,
as the case may be, becomes effective, and the Exercise Price shall be proportionately adjusted so that the aggregate Exercise Price payable
upon exercise in full of this Warrant shall remain the same.


 


(b)           Whenever
the Warrant Shares or the Exercise Price shall be adjusted pursuant to this Section 3, the Company shall deliver to the Holder a
written notice setting forth in reasonable detail the event requiring the adjustment and the method by which such adjustment was calculated
and specifying the new Warrant Shares and Exercise Price. All calculations under this Section 3 shall be made to the nearest one-one
hundredth of a share.


 


4.             No
Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this
Warrant, but in lieu of such fractional shares the Company shall make a cash payment therefor on the basis of the Exercise Price then
in effect.


 


5.             Broker-Assisted
Cashless Exercise. Subject to compliance with the provisions of Section 9, if (a) the Company is subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended, and (b) the Company’s Common Stock is publicly
traded at the time of the Holder’s exercise, the Holder may exercise the Warrant by executing and delivering the documents
necessary to irrevocably authorize a broker acceptable to the Company to sell shares of the Company’s Common Stock (or a
sufficient portion of such shares) acquired upon exercise of this Warrant and remit to the Company a sufficient portion of the sale
proceeds to pay the entire Exercise Price and any withholding tax obligation on the part of the
Company resulting from such exercise.

6.             Representations
of the Company. The Company represents that all corporate actions on the part of the Company, its officers, directors and stockholders
necessary for the sale and issuance of this Warrant have been taken.


 


7.             Shares
of Common Stock in Reserve. The Company shall at all times to reserve a sufficient number of authorized but unissued shares of Common
Stock for the purposes of this Warrant, and to take such action as may be necessary to ensure that all Warrant Shares issued upon exercise
of this Warrant will be duly and validly authorized and issued and fully paid and nonassessable.


 


8.             Rights
of Stockholders. The Holder shall not be entitled, as a warrant holder, to vote or receive dividends or be deemed the holder of the
Warrant Shares or any other securities of the Company which may at any time be issuable on the exercise hereof for any purpose, nor shall
anything contained herein be construed to confer upon the Holder, as a warrant holder, any of the rights of a stockholder of the Company
or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par
value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights
or otherwise until this Warrant shall have been exercised and the Warrant Shares purchasable upon the exercise hereof shall have become
deliverable, as provided herein.


 


9.             Compliance
with Securities Laws.




 


(a)           By
its acceptance of this Warrant, the Holder represents, warrants, and covenants unto the Company, and acknowledge as appropriate,

United Sates and regulations of the United States Securities and Exchange Commission (the “SEC”); (ii) the

dispose of (except exercise) this Warrant or any Warrant Shares issued to it pursuant to exercise hereof, except in accordance with
applicable securities laws.


 


(b)           Notwithstanding
anything to the contrary contained in this Warrant, if at any time specified herein for the issuance of Warrant Shares to the
Holder, any law, or any regulation or requirement of the SEC or any other federal, state or local governmental authority having
jurisdiction, shall require either the Company or the Holder to take any action in connection with the Warrant Shares then to be
issued, other than (i) customary approvals required by applicable corporation laws, or (ii) notice filings on SEC
Form D and similar or related federal, state or local filings (the actions described in clauses (i) and (ii) are
collectively referred to as the “Required Actions”), to the extent such action is required to be taken prior to
the issuance of such Warrant Shares the issuance of such Warrant Shares shall be deferred until such action shall have been taken.
The Company shall be under no obligation to take such action, other than a Required Action, and the Company shall have no liability
whatsoever as a result of the non-issuance of such Warrant Shares as a result of not taking such action, other than a Required

or mutilation of this Warrant, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to the Company,
and reimbursement to the Company of all reasonable expenses incidental thereto (and upon surrender and cancellation of this Warrant if
mutilated), the Company will execute and deliver a new Warrant of like tenor, in lieu of this Warrant.


 


11.           Issue

and Binding Effect. The Company and any Warrant Agent may deem and treat the registered Holder of this Warrant as the absolute owner

NOTICE OF ADJUSTMENT


 


September 29, 2021


 


[Address of Holder]


 


Ladies and Gentlemen:


 


Reference is made to that certain Warrant dated
September 29, 2021 issued by Benson Hill Inc., a Delaware corporation (the “Company”), to [ ] (the “Holder”).


 


Notice is hereby given pursuant
to Section 3(b) of the Warrant that the following adjustment(s) have been made to the Warrant: Pursuant to the terms of
that certain Merger Agreement, dated as of May 8, 2021, by and between the Company, Star Peak Corp II (“Star Peak”)
and STPC II Merger Sub Corp. (“Merger Sub”), the Company merged with and into Merger Sub and the Company was the surviving
entity and a wholly owned subsidiary of Star Peak Corp II (the “Merger”). In connection with the Merger, all Company
common stock that was issued and outstanding immediately prior to the closing of the Merger was cancelled and converted into the common
shares of Star Peak. In addition, all outstanding warrants of the Company automatically, by virtue of the Closing and without any action
on the part of the Company, Star Peak or the Holders, were assumed and converted into a warrant with respect to a number of Star Peak
common shares equal to the number of Company common units subject to each such warrant immediately prior to the closing multiplied by
the Exchange Ratio (as defined in the Merger Agreement).


 


This certifies that Holder
is entitled to purchase from Star Peak, at Holder’s option, fully paid and nonassessable common shares of Star Peak at a price of
nine dollars and 30/100 ($9.30) per share. The number of shares purchasable at such price upon the exercise of the Warrant is set forth
on Exhibit A attached hereto.
