		Re:	Executive Employment
Arrangement



 


Dear Britton:


 


This Agreement will amend and restate your
existing Employment Offer Letter with Nikola Corporation (the “Company”), dated as of March 26, 2019, effective
as of the close of the business combination contemplated by the Business Combination Agreement, dated as of March 2, 2020
(the “Merger Agreement”) by and among VectoIQ Acquisition Corp., VCTIQ Merger Sub Corp., and the Company (the “Effective
Date”).


 


You will continue in your current position
as the Company’s Chief Legal Officer and will continue to report to the Company’s Chief Executive Officer. Your responsibilities
include, but are not limited to, such employment duties as are usual and customary for this position and which are commensurate
with the duties, authorities and responsibilities of persons in similar capacities in similar sized companies. At the Company’s
request, you shall serve the Company and/or its subsidiaries and affiliates in other capacities in addition to the foregoing, consistent
with expectations for your position.


 


The terms of your employment
are as follows:


 


Employment Period.
Your employment shall continue indefinitely until terminated in accordance with the terms of this Agreement. Notwithstanding the
foregoing, your employment is terminable at will by the Company or by you at any time (for any reason or for no reason), subject
to the termination provisions of this Agreement.


 


Annual Salary.
You have indicated your interest in declining any salary in excess of $1 per year, without regard to Arizona’s minimum wage.
Accordingly, for purposes of this Agreement and due to your request, your annual salary will be $1, paid bi-weekly less payroll
deductions and all required withholdings. Your signature on this Agreement confirms your election.


 


Annual Bonus.
You have indicated your interest in declining participation in any annual cash bonus program provided by the Company, without regard
to your eligibility in any such program. Your signature on this Agreement confirms your election.


 






    


     


    

 


Stock Awards.
You will be eligible to receive stock awards under the Company’s equity incentive plan as in effect from time to time (the
 “Plan”). Subject to approval by the Company’s Board of Directors (the “Board”), you will be granted
an annual time-vested stock award (a “Time-Vested Award”) and a performance-based stock award (a “Performance
Award”) as soon as administratively practicable following the Effective Date and the effective registration of the securities
under the Plan on Form S-8. These awards are designed to reward you for significantly increasing the value of the Company’s
stock over time.


 


Each Time-Vested Award
that you are eligible to receive will consist of restricted stock units for shares of the Company’s common stock having a
value on the date of grant of not less than $3,000,000. These awards provide immediate and ongoing retention value over time, with
the vesting restrictions on the underlying shares lapsing on the third anniversary of their respective dates of grant (or, in the
case of your first Time-Vested Award, the third anniversary of the Effective Date) subject to your continued employment. The number
of shares associated with the first Time-Vested Award will be determined based upon a stock price of $10.00 as contemplated per
the Merger Agreement. Subsequent Time-Vested Awards would be granted annually, typically concurrent with stock awards to other
employees in the first quarter, with the number of shares determined based upon the Company’s closing stock price on the
date of grant.


 


The Performance Award
will consist of 2,428,000 restricted stock units that can be earned upon the achievement of pre-established “stretch”
stock price milestones described in the table below and your continued employment through the third anniversary of the Effective
Date. Each stock price milestone represents an incremental increase of $6 billion in the market capitalization of the Company and
unlocks a tranche of the total shares granted. This tiered performance structure ensures shareholders receive an incremental return
on their investment prior to you earning the associated incremental shares. Any and all shares that are earned upon the achievement
(defined as the Company’s stock price trading at or above the milestone for at least 20 consecutive trading days) of the
three stock price milestones during the period beginning on the date the Resale Shelf Registration Statement (as defined in Exhibit A
to the Merger Agreement, and which registration statement is required to be filed within 45 days of the Effective Date) is declared
effective by the SEC and ending on the third anniversary of the Effective Date (the “Performance Period”) will be delivered,
free of vesting restrictions, following certification by the Board within 30 days following the final day of the Performance Period.


 


The general structure
of the Performance Award is illustrated below, assuming a stock price of $10.00 on the grant date. The specific share price milestones
will be approved on the date of grant and included in the associated award document.


 


	Share Price Milestone	 	Market Capitalization at Price	 	Incremental
                                         Performance

                                                                                Shares
                                         Earned at

                                                                                Share Price Milestone
	 
	Below $25.00	 	Below $10 billion	 	 	0	 
	$25.00	 	$10 billion	 	 	534,000	 
	$40.00	 	$16 billion	 	 	801,000	 
	$55.00 or Above	 	$22+ billion	 	 	1,093,000	 




 


In the event of a Change
in Control (as defined in the Plan), the achievement of share price milestones under your Performance Award will be based on the
Company’s performance through the closing of such Change in Control. The amount of the Performance Award that would have
been earned based on this measurement will be converted to time-vested restricted stock units immediately prior to such Change
in Control (the “Converted Awards”). If the Converted Awards are assumed, substituted or otherwise continued by the
successor corporation (or a parent or subsidiary thereof), all vesting restrictions applicable to the Converted Awards will lapse
on the earlier of (i) the final day of the Performance Period subject to your continued employment with the successor corporation
(or a parent or subsidiary thereof) through such date, at which time such Converted Awards will be settled, and (ii) subject
to your compliance with the Severance Conditions (as defined below), the date of your Involuntary Termination of employment with
the successor corporation (or a parent or subsidiary thereof). All Time-Vested Awards and Converted Awards that are not assumed,
substituted or otherwise continued by the successor corporation (or a parent or subsidiary thereof) will fully vest and will be
settled immediately prior to the consummation of such Change in Control.

The terms and conditions
of each Time-Vested Award and the Performance Award will be set forth in separate award agreements in forms prescribed by the Company
(each, an “Award Agreement”), and all shares underlying the respective awards will contain the right to receive dividend
equivalents, if any, subject to the same vesting conditions as the shares underlying the stock awards. The stock awards shall be
governed in all respects by the terms and conditions of the Plan and the applicable Award Agreement.


 


Stock Option Awards.
On the Effective Date, all unvested stock option awards that you hold at such time will fully vest.


 


Benefits. You
(and your spouse and/or eligible dependents to the extent provided in the applicable plans and programs) are eligible to participate
in and be covered under the health, welfare and financial benefit plans and programs maintained by the Company for the benefit
of its employees, pursuant to the terms of such plans, on the same terms and conditions as those applicable to similarly situated
executives. Detailed descriptions of the Company’s benefit plans are available and will be provided to you upon request.
Your eligibility to receive such benefits will be subject in each case to the generally applicable terms and conditions for the
benefits in question and to the determinations of any person or committee administering such benefits. The Company may modify or
terminate any benefits plan or program from time to time in its sole discretion.


 


Expenses. You
are entitled to receive prompt reimbursement for all reasonable business expenses incurred in connection with the performance of
your duties in accordance with the policies, practices and procedures of the Company.


 


Vacation. You
are entitled to paid vacation in accordance with the policies, practices and procedures of the Company.


 


Indemnification/Legal
Fees. The Company agrees that you will be entitled to the same indemnification rights as the Company grants to other officers
of the Company, as in effect from time to time. The Company will maintain a directors and officers liability policy covering you
with coverage comparable or equal to that provided to other officers of the Company. In the event of any dispute over your entitlement
to payments or benefits hereunder, the Company shall advance you an amount equal to your monthly legal fees incurred in connection
with such dispute until there is a final non-appealable decision by a court that you are not entitled to such payment or benefit.

Termination of Employment.
In the event of an Involuntary Termination of your employment at any time, and subject to (i) your execution of a general
release of claims in favor of the Company in substantially the form attached as Exhibit A (the “Release”), (ii) your
non-revocation of the Release and it becoming effective within sixty (60) days following the date of your termination of employment
(the “Termination Date”), and (iii) your faithful observance of the terms of such Release (such conditions, the
 “Severance Conditions”), then you shall be entitled to the following severance benefits (the “Severance Benefits”):


 


		·	Severance Payment. The Company will pay you a cash lump sum in an amount equal to $1,050,000,
less applicable withholding.



 


		·	Stock Awards.



 


		o	Restricted Stock, Restricted Stock Units and Stock Options. All outstanding restricted stock
awards, restricted stock units (other than the Performance Award but including the Converted Awards) and stock options will immediately
vest in full. Unexercised stock options will remain exercisable for three years following your Termination Date.



 


		o	Performance Award. Following certification by the Board within 30 days following your Termination
Date, the Performance Award will vest in an amount based upon the stock price milestones achieved prior to your Termination Date,
pro-rated for the amount of time that you remained employed during the Performance Period.



 


		·	Benefits Continuation. The Company will pay to you a cash lump sum equal in value to 18
months of COBRA benefits coverage, less applicable withholding.



 


The cash Severance
Benefits will be paid on the first regular payroll date following the date that your Release becomes effective, subject to compliance
with Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”).


 


For the avoidance of
doubt, if you independently and unilaterally decide to end your employment at the Company without Good Reason, or if you are terminated
for Cause, or if your employment is terminated due to your Death or Disability, you will not be entitled to receive any Severance
Benefits.


 


You may terminate your
employment with the Company at any time and for any reason whatsoever simply by notifying the Company. Likewise, the Company may
terminate your employment at any time, with or without cause or advance notice. Your employment at-will status can only be modified
in a written agreement signed by you and by an authorized officer of the Company.


 


Section 409A. Notwithstanding
anything to the contrary in this Agreement, no compensation or benefits, including any Severance Benefits, stock awards, consulting
payments or other benefits payable due to termination, shall be paid to you during the six-month period following termination
if the Company determines that paying such amounts would be a prohibited distribution under Section 409A. If the payment of
any such amounts is so delayed, then on the first day of the seventh month following termination (or such earlier date upon which
such amount can be paid under Section 409A without resulting in a prohibited distribution) the Company shall pay to you a lump-sum amount
equal to the cumulative amount that would have otherwise been payable during such period. In addition, to the extent required in
order to comply with Section 409A, you shall not be considered to have terminated employment with the Company for purposes
of this Agreement and no payment of such amounts due pursuant to your termination shall be due until you would be considered to
have incurred a “separation from service” from the Company within the meaning of Section 409A. Each such amount
which constitutes deferred compensation subject to Section 409A shall be construed as a separate identified payment for purposes
of Section 409A. If the period during which you have discretion to execute or revoke the Release straddles two calendar years,
then the Company will make the payment of amounts that are subject to Section 409A and contingent on the effectiveness of
such Release starting in the second of such years regardless of which year you actually deliver the Release. You may not, directly
or indirectly, designate the calendar year of payment of any amounts subject to Section 409A. The intent of the parties is
that the payments and benefits under this Agreement comply with or be exempt from Section 409A and, accordingly, to the maximum
extent permitted, this Agreement shall be interpreted to be exempt from or in compliance therewith.

EXHIBIT A


 




Severance Agreement and Release


 


I. Release of Claims. In exchange

and each of them, as well as each of its and their assignees, successors, directors, officers, stockholders, partners, representatives,

the Company, the Company’s by-laws, the Company’s D&O insurance and otherwise), (3) vested rights or benefits
under Executive’s 401k or other plans, or (4) Executive’s workers’ compensation rights and, provided further,
that nothing in this Agreement shall prevent Executive from filing, cooperating with, or participating in any proceeding before

acknowledges and agrees that by entering into this release, Executive is waiving any and all rights or claims that Executive may

D. Nothing in this release prevents or precludes

insurers, attorneys, agents or employees, past or present, or any of them (individually and collectively), hereby releases Executive
from and with respect to any and all claims, agreements, obligations, demands and causes of action, known or unknown, suspected
or unsuspected, arising out of or in any way connected with events, acts, conduct, or omissions occurring at any time prior to

not apply to any statements that Executive makes in response to any defamatory or disparaging statements made by the Company (in
its formal public statements), its executive officers and/or its directors regarding Executive or Executive’s performance
as an employee of the Company so long as Executive’s statements are, in the reasonable, good faith judgment of Executive,
true and extend no further than addressing such statements by the Company.


 


VI. Forfeiture of Severance Benefits.
Executive acknowledges and agrees that any material breach of this Agreement, the Employment Agreement, or the PIIA, including
any of the restrictive covenants set forth therein, shall entitle the Company immediately to recover and/or cease providing the
Severance Benefits, except as provided by law. All other provisions of this Agreement, the Employment Agreement, and the PIIA shall
remain in full force and effect.
