Explanation of Responses:
(1)	On September 29, 2021 (the "Closing Date"), the Reporting Person was granted 20,403 restricted stock units as Earn Out Awards in connection with the consummation of the business combination pursuant to the terms of the merger agreement dated as of May 8, 2021 by and among Star Peak Corp II (the Issuer's predecessor), STPC Merger Sub Corp. and Benson Hill, Inc. (n/k/a Benson Hill Holdings, Inc.) (the "Business Combination"). The restricted stock units vest (i) one-half if the dollar volume-weighted average closing price is greater than or equal to $14.00 over any 20 trading days within any 30 consecutive trading day period; and (ii) one-half if the dollar volume-weighted average closing price is greater than or equal to $16.00 over any 20 trading days within any 30 consecutive trading day period.
(2)	Any restricted stock units that do not vest within three years of the Closing Date will be forfeited and canceled. Settlement will generally occur within 10 days of vesting and may at the discretion of the plan administrator be settled in each or partly in cash and partly in shares.
(3)	The Reporting Person's Form 3 filed on October 8, 2021 inadvertently overstated his ownership by one restricted stock unit.
(4)	Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.
