EMPLOYMENT AGREEMENT
THIS EMPLOYMENT AGREEMENT (this “Agreement”), dated as of June _11___, 2018, by
and between Renewable Energy Group, Inc., a Delaware corporation (the
“Company”), and Gary Haer (“Executive”).
WHEREAS, the Company desires to continue to employ Executive, and Executive
desires to continue to be employed by the Company, on the terms and conditions
set forth herein.
NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth below, and for other good and valuable consideration, it is hereby
covenanted and agreed by the Company and Executive as follows:
1.Term and Duties.
1.1    Term. The Company hereby continues to employ Executive for a term (as the
same may be extended, the “Term”) commencing as of May 21, 2018 and continuing
until May 21, 2021, unless terminated earlier in accordance with the provisions
of Section 7. On May 21, 2021, the Term shall automatically be extended for
successive one-year periods in accordance with the terms of this Agreement
(subject to termination as aforesaid) unless either party notifies the other
party of non-renewal in writing, in accordance with Section 12, 90 days prior to
the expiration of the initial period or any subsequent renewal period.
1.2    Duties. During the Term, Executive shall be employed by the Company as
Vice President, Sales and Marketing of the Company, and, as such, Executive
shall faithfully perform for the Company the duties of said office and shall
perform such other duties of an executive, managerial or administrative nature
as shall be specified and designated from time to time by the Board of Directors
(the “Board”) of the Company. Executive shall report to the Chief Executive
Officer (the “CEO”) of the Company. Executive shall devote substantially all of
his business time and effort to the performance of his duties hereunder, except
that Executive may devote reasonable time and attention to civic, charitable,
business or social activities so long as such activities do not interfere with
Executive’s employment duties. Executive shall comply with the policies,
standards, and regulations established from time to time by the Company.
2.    Location. During the Term, Executive shall perform his duties under this
Agreement at the Company’s headquarters, subject to travel required by
Executive’s position and consistent with the reasonable business needs of the
Company.
3.    Office Space and Administrative Support. During the Term, the Company
shall furnish Executive with office space, equipment, supplies and such other
facilities and personnel at the Company’s headquarters commensurate with
Executive’s position.
4.    Compensation.
4.1    Annual Salary. During the Term, the Company shall pay Executive a base
salary at the rate of $330,000 per annum, in accordance with the customary
payroll practices of the Company applicable to senior executives, but not less
frequently than monthly. The Compensation

--------------------------------------------------------------------------------

Committee (the “Compensation Committee”) of the Board shall review Executive’s
base salary during the Term and may increase such amount as it may deem
advisable (such salary, as the same may be increased, the “Annual Salary”). The
Annual Salary shall be prorated for any partial calendar year during the Term.
4.2    Bonus and Incentive Compensation. Executive shall be entitled to
participate in the Company’s incentive compensation programs as follows:
(a)    Annual Bonus Compensation. During the Term, Executive shall be eligible
to receive an annual bonus (the “Annual Bonus”) pursuant to the terms and
conditions of the Company’s annual incentive plan for executive officers (or any
successor thereto). Based upon attainment of performance goals predetermined by
the Compensation Committee, Executive shall be entitled to an Annual Bonus
payment at a target level of 50% of Executive’s Annual Salary. The Compensation
Committee shall review the target annual bonus percentage during the Term and
may increase such percentage as it may deem advisable (such target annual bonus,
as the same may be increased, the “Target Annual Bonus”).
(b)    Equity Incentive Compensation. During the Term, Executive shall be
eligible to participate in the Company’s equity incentive plans pursuant to the
Company’s Amended and Restated 2009 Stock Incentive Plan (the “Plan”) (or any
successor thereto) or such other plans or programs as the Compensation Committee
shall determine. In the event that the vesting terms of the applicable award
agreements governing Executive’s equity-based incentive awards differ from or
are in conflict with the vesting terms set forth in Section 7 of this Agreement,
the terms of this Agreement shall govern and control.
4.3    Benefits – In General. During the Term, Executive shall be permitted to
participate in any group health, dental, vision, disability and life insurance
benefit plans and programs, retirement plans, fringe benefit programs, paid
time-off policies and similar benefits that may be available to other senior
executives of the Company generally, on the same terms as such other executives,
in each case to the extent that Executive is eligible under the terms of such
plans or programs. The Company reserves the right to modify, suspend or
discontinue any of its health or welfare benefit, retirement, fringe benefit,
paid time-off (“PTO”) and other plans, practices, policies or programs at any
time without recourse by Executive.
4.4    Expenses. The Company shall pay or reimburse Executive for all ordinary
and reasonable out-of-pocket expenses incurred by Executive during the Term in
the performance of Executive’s services under this Agreement; provided that such
expenses are incurred and accounted for by Executive in accordance with the
policies and procedures established from time to time by the Company.
5.    Clawback. Notwithstanding anything in this Agreement to the contrary,
Executive acknowledges that the Company may be entitled or required by law, the
Company’s policy (the “Clawback Policy”) or the requirements of an exchange on
which the Company’s shares are listed for trading, to recoup cash, equity or
other compensation paid or provided to Executive pursuant to this Agreement or
otherwise, and Executive agrees to comply with any Company request or demand for
recoupment. Executive acknowledges that the Clawback Policy may be modified from

time to time in the sole discretion of the Company and without the consent of
Executive, and that such modification shall be deemed to amend this Agreement.

harmless to the same extent as other senior executives of the Company.
7.    Termination of Employment.
7.1    Termination upon Death or Disability. If Executive dies during the Term,
the obligations of the Company to or with respect to Executive shall terminate
in their entirety except as otherwise provided under this Section 7.1. If
Executive becomes eligible for disability benefits under the Company’s long-term
disability plans and arrangements (or, if none, if Executive by virtue of ill
health or other disability is unable to perform substantially and continuously
the duties assigned to him for at least 120 consecutive or non-consecutive days
out of any consecutive 12-month period), the Company shall have the right, to
the extent permitted by law, to terminate the employment of Executive upon
notice in writing to Executive; provided that the Company shall have no right to
terminate Executive’s employment if, in the reasonable opinion of a qualified
physician acceptable to the Company, it is substantially certain that Executive
shall be able to resume Executive’s duties on a regular full-time basis within
30 days of the date Executive receives notice of such termination. Upon death or
other termination of employment by virtue of disability in accordance with this
Section 7.1, Executive (or Executive’s estate or beneficiaries in the case of
the death of Executive) shall have no right to receive any compensation or
benefits hereunder on and after the effective date of the termination of
employment other than (a) the Executive’s Annual Salary and other benefits
earned and accrued under this Agreement prior to the date of termination (and
reimbursement under this Agreement for expenses incurred prior to the date of
termination); and (b) a lump sum cash payment equal to the Annual Bonus for the
calendar year in which Executive’s employment hereunder terminates, prorated
based on the period beginning on January 1 and ending on the date on which
Executive’s employment is terminated pursuant to this Section 7.1, and
calculated based on actual performance through the end of the applicable
performance year (but in no event shall the amount of the bonus payable to
Executive be greater than the prorated portion of Executive’s Target Annual
Bonus for such year), payable at the same time as annual bonuses of other senior
executives of the Company, but in no event later than March 15 of the year
following the year with respect to which such Annual Bonus is payable.

Good Reason.

Confidentiality Agreement;

provided, that the Company shall not be permitted to terminate Executive for
Cause except on written notice given to Executive at any time following the
occurrence of any of the events described above. Notwithstanding the foregoing,
Executive shall not be deemed to have been terminated for Cause under clause
(i), (v), (vi), (vii) or (viii) above unless the Company provided written notice
to Executive setting forth in reasonable detail the reasons for the Company’s
intention to terminate for Cause and, as determined in the sole discretion of
the Board, Executive failed within 30 days to cure the event or deficiency set
forth in the written notice.
(b)    For purposes of this Agreement, “Good Reason” shall mean, unless
otherwise consented to by Executive:
(i)
a material reduction of Executive’s Annual Salary or Target Annual Bonus

notice of termination on account thereof (specifying a termination date no
earlier than 30 days from the date of such notice) is given by Executive to the
Company no later than 30 days after the time at which Executive first becomes or
should have become aware of the event or condition purportedly giving rise to
Good Reason; and, in such event, the Company shall have 30 days from the date
notice of such a termination is given to cure such event or condition and, if
the Company does so, such event or condition shall not constitute Good Reason
hereunder, but, if the Company does not cure such

4

--------------------------------------------------------------------------------

event within the 30-day period, Executive must terminate his employment not
later than 45 days after the end of such 30-day period in order for Good Reason
to exist.
(c)    The Company may terminate Executive’s employment hereunder for Cause upon
30 days’ prior written notice to Executive and Executive may terminate his
employment at any time upon 60 days prior written notice to the Company without
Good Reason, in which case (i) Executive shall receive the Executive’s Annual
Salary and other benefits (but, in all events, and without increasing
Executive’s rights under any other provision hereof, excluding any Annual Bonus
not yet paid) earned and accrued under this Agreement prior to Executive’s
termination of employment (and reimbursement under this Agreement for expenses

the termination of employment, or any other rights hereunder.

performance through the end of the applicable performance year (but in no event
shall the amount of the bonus payable to Executive be greater than the prorated

employee” within the meaning of Treasury Regulation Section 1.409A-1(i) as of
the date of Executive’s separation from service, the provisions of this Section

Code of 1986, as amended (the “Code”), and the regulations and interpretive
guidance promulgated thereunder (collectively, “Section 409A”). No distribution

after the date that is six months after Executive’s separation from service (or,
if earlier, as soon as practicable, and in all events within 10 days, after the
date of Executive’s death).
8.    Limitation on Payments.

9

--------------------------------------------------------------------------------

8.1    General. In the event that the payments and benefits (the “Payments”)
paid or provided to Executive under this Agreement or otherwise (a) constitute
“parachute payments” within the meaning of Section 280G of the Code (“Section
280G”), and (b) but for this Section 8, would be subject to the excise tax
imposed by Section 4999 of the Code (“Section 4999”), then the Payments shall be
either (x) delivered in full, or (y) delivered as to such lesser extent which
would result in no portion of the Payments being subject to excise tax under
Section 4999, whichever of the foregoing amounts, taking into account the
applicable federal, state and local income taxes and the excise tax imposed by
Section 4999, results in the receipt by Executive on an after-tax basis, of the
greatest amount of the Payments, notwithstanding that all or some portion of the
Payments may be taxable under Section 4999. The provisions of this Section 8
shall apply if, at the time of any change in ownership or control of the Company
(within the meaning of Section 280G), the Company is an entity whose stock is
readily tradable on an established securities market (or otherwise), within the
meaning of Section 280G.
8.2    Accountants’ Determinations. Unless the Company and Executive otherwise
agree in writing, any determination required under this Section 8 shall be made
in writing by the Company’s independent public accountants immediately prior to
the Change of Control (the “Accountants”), whose determination shall be
conclusive and binding upon Executive and the Company for all purposes. For
purposes of making the calculations required by this Section 8, the Accountants
may make reasonable assumptions and approximations concerning applicable taxes
and may rely on reasonable, good faith interpretations concerning the
application of Section 280G and Section 4999. The Company and Executive shall
furnish to the Accountants such information and documents as the Accountants may
reasonably request in order to make a determination under this Section 8.  The
Company shall bear all costs the Accountants may reasonably incur in connection
with any calculations contemplated by this Section 8.  If a reduction in the
Payments constituting “parachute payments” as defined in Section 280G is
necessary so that benefits are delivered to a lesser extent, reduction shall
occur in the following order: (a) reduction of the cash severance payments;
(b) cancellation of accelerated vesting of equity awards that do not qualify for
special valuation under Q&A 24(c) of the regulations under Section 280G; (c)
cancellation of other equity awards; and (d) reduction of continued employee
benefits.  In the event that the accelerated vesting of equity awards is to be
cancelled, such vesting acceleration shall be cancelled in the reverse
chronological order of Executive’s equity awards’ grant dates.
9.    Restrictive Covenants. Simultaneously with the execution of this
Agreement, Executive shall execute the Employee Non-Competition and
Confidentiality Agreement attached hereto as Exhibit A (the “Non-Competition and
Confidentiality Agreement”).
10.    Arbitration. All disputes between the parties or any claims concerning
the performance, breach, construction or interpretation of this Agreement, or in
any manner arising out of this Agreement, shall be submitted to binding
arbitration in accordance with the Commercial Arbitration Rules, as amended from
time to time, of the American Arbitration Association (the “AAA”), which
arbitration shall be carried out in the manner set forth below:
(i)
Within fifteen days after written notice by one party to the other party of its
demand for arbitration, which demand shall set forth the name

10

--------------------------------------------------------------------------------

and address of its designated arbitrator, the other party shall appoint its
designated arbitrator and so notify the demanding party. Within fifteen days
thereafter, the two arbitrators so appointed shall appoint the third arbitrator.
If the two appointed arbitrators cannot agree on the third arbitrator, then the
AAA shall appoint an independent arbitrator as the third arbitrator. The dispute
shall be heard by the arbitrators within 90 days after appointment of the third
arbitrator. The decision of any two or all three of the arbitrators shall be
binding upon the parties without any right of appeal. The decision of the
arbitrators shall be final and binding upon the Company, its successors and
assigns, and upon Executive, his heirs, personal representatives, and legal
representatives.
(ii)
The arbitration proceedings shall take place in Des Moines, Iowa, and the
judgment and determination of such proceedings shall be binding on all parties.
Judgment upon any award rendered by the arbitrators may be entered into any
court having competent jurisdiction without any right of appeal.

(iii)
Each party shall pay its or his own expenses of arbitration, and the expenses of
the arbitrators and the arbitration proceeding shall be shared equally. However,
if in the opinion of a majority of the arbitrators, any claim or defense was
unreasonable, the arbitrators may assess, as part of their award, all or any
part of the arbitration expenses of the other party (including reasonable
attorneys’ fees) and of the arbitrators and the arbitration proceeding.

11.    Severability. As the provisions of this Agreement are independent of and
severable from each other, the Company and Executive agree that if, in any
action before any court or agency legally empowered to enforce this Agreement,
any term, restriction, covenant, or promise hereof is found to be unreasonable
or otherwise unenforceable, then such decision shall not affect the validity of
the other provisions of this Agreement, and such invalid term, restriction,
covenant, or promise shall also be deemed modified to the extent necessary to
make it enforceable.
12.    Notice. For purposes of this Agreement, notices, demands and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when received if delivered in person, the next
business day if delivered by overnight commercial courier (e.g., Federal
Express), or the third business day if mailed by United States certified mail,

or the other subject matters of this Agreement (including without limitation any
term sheets) are superseded in their entirety by this Agreement.
16.    Waivers; Amendments. This Agreement may be amended, superseded, canceled,
renewed or extended, and the terms hereof may be waived, only by a written
instrument signed by the parties or, in the case of a waiver, by the party
waiving compliance. No delay on the part of any party in exercising any right,
power or privilege hereunder shall operate as a waiver thereof, nor shall any
waiver on the part of any party of any such right, power or privilege nor any
single or partial exercise of any such right, power or privilege, preclude any
other or further exercise thereof or the exercise of any other such right, power
or privilege.
17.    Counterparts. This Agreement may be executed in counterparts, each of
which shall be deemed an original, but which together shall be one and the same
instrument.

other professionals as he deems necessary for entering into this Agreement, and
he has not relied upon the advice of the Company or the Company’s officers,
directors, or employees.
19.    Interpretation. As both parties having had the opportunity to consult
with legal counsel, no provision of this Agreement shall be construed against or
interpreted to the disadvantage of any party by reason of such party having, or
being deemed to have, drafted, devised, or imposed such provision.
20.    Withholding. Any payments made to Executive under this Agreement shall be
reduced by any applicable withholding taxes or other amounts required to be
withheld by law or contract.
21.    Section 409A. This Agreement is intended to meet, or be exempt from, the
requirements of Section 409A, with respect to amounts subject thereto, and shall
be interpreted and construed consistent with that intent. No expenses eligible
for reimbursement, or in-kind benefits to be provided, during any calendar year
shall affect the amounts eligible for reimbursement in any other calendar year,
to the extent subject to the requirements of Section 409A, and no such right to
reimbursement or right to in-kind benefits shall be subject to liquidation or
exchange for any other benefit. For purposes of Section 409A, each payment in a
series of installment payments provided under this Agreement shall be treated as
a separate payment. Any payments to be made under this Agreement upon a
termination of employment shall only be made upon a “separation from service”
under Section 409A. Notwithstanding the foregoing, the Company makes no
representations that the payments and benefits provided under this Agreement
comply with Section 409A or any exemption therefrom, and in no event shall the
Company be liable for all or any portion of any taxes, penalties, interest or
other expenses that may be incurred by Executive on account of non-compliance
with Section 409A.
22.    Survivability. Those provisions and obligations of this Agreement which
are intended to survive shall survive notwithstanding termination of Executive’s
employment with the Company.
23.    Set-off/No Mitigation. The Company’s obligation to pay Executive the
amounts provided and to make the arrangements provided hereunder shall be
subject to set-off, counterclaim or recoupment of amounts owed by Executive to
the Company or its affiliates. The Company agrees that, if Executive’s
employment is terminated hereunder, Executive shall not be obligated to seek
other employment in mitigation of the amounts payable or arrangements made under
any provision of this Agreement, and the obtaining of any such other employment
shall in no event effect any reduction of the Company’s obligations to make the
payments and arrangements required to be made under this Agreement.
24.    Cooperation. Executive shall make himself reasonably available, taking
into account his other business and personal commitments, to cooperate with the
Company, its subsidiaries and affiliates and any of their respective officers,
directors, shareholders, employees or agents in connection with any
investigation, inquiry, administrative proceeding or litigation relating to any
matter in which Executive becomes involved or of which Executive has knowledge
as a result of Executive’s service with the Company or any of its subsidiaries
or affiliates.
