This AGREEMENT is made and entered into by and between Renewable Energy Group, Inc., (herein “REG” or “Employer”) and Brad Albin (herein “Employee”) effective as of June 1, 2021 (“Effective Date”).

WHEREAS, REG and Employee entered into an Employment Agreement dated September 29, 2017 and all amendments thereto (collectively the “Employment Agreement”); and

WHEREAS, REG desires to terminate Employee’s employment on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual promises contained in this Agreement, REG and Employee have reached the following agreement:

1.Termination by the Company. Pursuant to Section 7.3 of the Employment Agreement, REG hereby gives notice that Employee’s employment with REG will be terminated without cause effective June 1, 2021 (“Termination Date”) and his first day off of the payroll will be June 2, 2021. Employee hereby waives the 30 days’ prior written notice requirement under Section 7.3(a) of the Employment Agreement in order to terminate his Employment Agreement on the Effective Date. Further, this Agreement hall constitute the general release under Section 7.3(a)(i) of the Employment Agreement. REG will pay Employee pursuant to Section 4 of the Employment Agreement through his Termination Date, whereupon Section 7.3 of the Employment Agreement shall apply. The schedule of payments to be made pursuant to Section 7.3 is attached. All other terms of the Employment Agreement intended to survive the termination of the Employment Agreement shall remain in force and effect.

2.Stock Incentives. In exchange for the release of claims and other agreements as set out herein and in exchange for, and contingent upon, Employee signing this Agreement, REG

agrees to allow early vesting of the Restricted Stock Units (“RSUs”) granted to Employee on December 14, 2018 (the “2018 Grant”). Namely, the 14,907 RSUs granted by the 2018 Grant shall fully vest upon Employee’s Termination Date, with standard administrative delays to complete the conversion of the RSUs to stock, the issuance of the shares, and the implementation of tax decisions. Employee acknowledges that all other stock incentives, including without limitation, RSUs, Performance-based RSUs, and Stock Appreciation Rights (“SARs”), shall be exercisable, vest, or be forfeited without modification according to the original terms under the Amended and Restated 2009 Stock Incentive Plan. For clarity, any and all SARs held by Employee shall only be exercisable for the period and under the terms and conditions set forth in the Amended and Restated 2009 Stock Incentive Plan.

4.Release of Liability. Based on the consideration set forth in this Agreement, Employee, on his own behalf and on behalf of anyone else who may make a claim for him, hereby irrevocably and unconditionally voluntarily promises, releases, and forever discharges REG, its officers, directors, employees, agents, representatives, insurers and affiliates and their officers, directors, employees, agents, representatives and insurers (herein the “Persons Released”) from any causes of action, complaints, claims, obligations, damages, and expenses of any nature whatsoever, in law or in equity, which he ever had, now has, or hereinafter may have up to and including the Effective Date of this Agreement. This release includes all claims that Employee may have now under any federal, state, or local law, regulation or ordinance, whether now known or unknown or whichever existed or now exist, including, without limitation, all liabilities, rights or claims arising from or in connection with Employee’s employment with REG and its affiliates and his separation from REG.

Employee agrees that this instrument shall be a complete defense to any action or proceedings that may be brought, instituted, or taken against those released with regard to any matter herein released and shall forever be a complete bar to the commencement or prosecution of any action or proceeding whatsoever against those released, to the fullest extent of the law.
