This Severance Agreement and Release (“Agreement”) is made by and between Bruce Bennett (“EMPLOYEE”) and Benson Hill Holdings, Inc. (“EMPLOYER”). The terms of this Agreement are as follows:

A.EMPLOYEE has been employed by EMPLOYER pursuant to that certain Executive Employment Agreement, dated September 29, 2021 (the “Employment Agreement”);

B.The parties are terminating their employment relationship;

C.The parties agree EMPLOYEE’s termination is without “Cause” as that term is defined in the Employment Agreement, when entitles EMPLOYEE to certain severance benefits; and

D.The parties desire to settle and resolve any and all disputes and claims that have been or could have been asserted between them or any other affiliated entities, up to and including the date of this Agreement.

For and in consideration of the mutual releases, covenants and undertakings hereinafter set forth, and for other good and valuable consideration, which each party hereby acknowledges, it is agreed as follows:

1.Severance. In exchange for the promises outlined in this Agreement, and in satisfaction of all severance benefits under the Employment Agreement, EMPLOYER agrees to:

a.Pay EMPLOYEE the amount of $452,944.00, (“Severance Payment”) which is equal to twelve months’ (the “Severance Period”) base pay as of EMPLOYEE’s termination of employment, less applicable tax withholdings and deductions. Payment of the Severance Payment will be in equal installments over the course of the Severance Period in accordance with EMPLOYER’s normal payroll practices, but no less frequently than monthly.

b.Pay EMPLOYEE a bonus for the 2023 calendar year based on the achievement of applicable EMPLOYER and EMPLOYEE performance metrics consistent with the EMPLOYER’s Annual Team Incentive Plan, as determined by the Board, or the compensation committee of the Board (the “Compensation Committee”). EMPLOYEE acknowledges that the Board or Compensation Committee will determine the annual bonuses for all participants, including EMPLOYEE, under the Annual Team Incentive Plan in accordance with the normal processes and procedures for determining bonuses under the Annual Team Incentive Plan, and such amount for EMPLOYEE could be $0 for 2023. This 2023 bonus, if any, will be paid at the same time the annual bonuses are paid to the EMPLOYER’s executives for 2023, less applicable tax withholdings and deductions.

c.EMPLOYEE acknowledges and agrees that EMPLOYEE provided no service to EMPLOYER during 2024 and is therefore not entitled to any annual bonus for calendar year 2024.

d.Provided EMPLOYEE timely and properly elects continuation coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) for

medical, dental and/or vision benefits, EMPLOYER will reimburse EMPLOYEE for EMPLOYER’s portion of the monthly COBRA premium paid by EMPLOYEE for EMPLOYEE and EMPLOYEE’s covered dependents for the same number of months in the Severance Period. EMPLOYEE will remain responsible for EMPLOYEE’s portion of the COBRA premium at the same level of similarly situated active employees. EMPLOYEE and EMPLOYEE’s covered dependents must have been enrolled in coverage prior to EMPLOYEE’s termination of employment to be eligible for the premium subsidy. Such reimbursement may either (x) be paid to EMPLOYEE on the first payroll date of the month immediately following the month in which EMPLOYEE timely remits the premium payment, or (y) be remitted directly to the COBRA administrator on EMPLOYEE’s behalf. EMPLOYEE will be eligible to receive such reimbursement until the earliest of: (A) the expiration of EMPLOYEE’s Severance Period; (B) the date EMPLOYEE is no longer eligible to receive COBRA continuation coverage; (C) the date on which EMPLOYEE becomes eligible to receive substantially similar coverage from another employer or other source; or (D) EMPLOYEE fails to remit payment for EMPLOYEE’s portion of the COBRA premium.

The Severance Payment and other severance benefits described in this paragraph shall not be paid or provided until after the 7-day revocation period (Paragraph 9) has ended and EMPLOYEE has not revoked this Agreement. EMPLOYER shall issue a Form W-2 for such Severance Payment and other severance benefits. EMPLOYEE agrees that the Severance Payment and other severance benefits are not otherwise due and owing to EMPLOYEE and that EMPLOYEE is not otherwise entitled to any sum of money from EMPLOYER.
