Form of Benson Hill, Inc. Restricted Stock Unit Agreement2023 Annual LTIP Award for Jason Bull, Yevgeny Fundler and Dean Freeman granted under the Benson Hill Inc. 2021 Omnibus Incentive Plan

This Restricted Stock Unit Agreement (this “Agreement”) is made and entered into effective March 16, 2023 (the “Grant Date”) by and between BENSON HILL, INC. (the “Company”) and the individual signatory to this Agreement (“you”). The Company adopted the Benson Hill, Inc. 2021 Omnibus Incentive Plan (the “Plan”) pursuant to which awards of Restricted Stock Units may be granted.

Pursuant to the Company’s Long-Term Incentive Program (the “LTIP”), the Company hereby issues you the number of Restricted Stock Units as reflected in your E-Trade account (the “2023 RSUs”). Your 2023 RSUs are subject to the following terms and conditions, as well as the terms and conditions of the Plan. Unless otherwise specified, capitalized terms used but not defined below have the meaning ascribed to them in the Plan.

1.    Vesting and Settlement. Your “Vesting Start Date” for the 2023 RSUs is the Grant Date. Subject to your continued service through the applicable vesting date, 33% of your 2023 RSUs will vest each annual anniversary of the Vesting Start Date, becoming 100% vested on the 3rd annual anniversary of the Vesting Start Date.

If (i) your service is terminated as a result of a “Qualifying Termination” (as that term is defined in the Company’s Executive Severance Plan as of the Grant Date), (ii) such Qualifying Termination occurs within 12 months following a Change in Control, and (iii) and subject to you executing a “Release” (as that term is defined in the Company’s Executive Severance Plan as of the Grant Date) then any unvested portion of your 2023 RSUs will vest on your “Release Effective Date” (as that term is defined in the Company’s Executive Severance Plan as of the Grant Date).

If your service terminates for any other reason before your 2023 RSUs vest, you will automatically forfeit all interests and rights related to your unvested 2023 RSUs upon such termination of your service. You will have no right or interest in any forfeited 2023 RSUs and neither the Company nor any Affiliate will have any further obligations under this Agreement.

Subject to Section 6 (Taxes) of this Agreement, any portion of your 2023 RSUs that has achieved the vesting requirements will be settled within 60 days following the applicable vesting date. Upon settlement of your 2023 RSUs, the Company shall (a) issue and deliver to you the number of shares of Common Stock equal to the number of 2023 RSUs that vest on the vesting date (subject to any reduction of delivered shares via a net settlement agreement with the Company, in the Company’s discretion, for withholding tax purposes), and (b) enter your name on the books of the Company as the shareholder of record with respect to the shares of Common Stock delivered to you.

If, prior to an unvested 2023 RSU’s settlement date, the Company declares a dividend on the shares of Common Stock, the Company will credit an account with an amount equal to the dividends that would have been paid to you had you been issued one share of Common Stock on the Grant Date for each unvested 2023 RSU (“Dividend Equivalents”). Dividend Equivalents shall be subject to the same vesting and forfeiture restrictions as the unvested 2023 RSUs to which they are attributable and shall be paid on the same date that the unvested 2023 RSUs to which they are attributable are settled in accordance with Section 1. To the extent vested, Dividend Equivalents credited to your account shall be distributed in cash or, at the discretion of the Committee, in shares of Common Stock having a Fair Market Value equal to the amount of the Dividend Equivalents, if any.

Notwithstanding any action the Company takes with respect to any or all income tax, social insurance, payroll tax, or other tax-related withholding, the ultimate liability for all such taxes is and remains your responsibility and the Company (a) makes no representation or undertakings regarding the treatment of any such taxes in connection with the grant, vesting or settlement of your 2023 RSUs or the subsequent sale of any shares; and (b) does not commit to structure your 2023 RSUs to reduce or eliminate your tax liability.

This Agreement is intended to comply with Code Section 409A or an exemption thereunder and shall be construed and interpreted in a manner that is consistent with the requirements for avoiding additional taxes or penalties under Code Section 409A. Notwithstanding the foregoing, neither the Company nor any Affiliate makes any representations that the payments and benefits provided under this Agreement comply with Code Section 409A and in no event shall the Company nor any Affiliate be liable

for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by you on account of non-compliance with Code Section 409A.
