Employee agrees that any inventions, products, processes, apparatus, designs, improvements or business-related suggestions and information

EXECUTION COPY 
  

 
developed by him, solely or jointly with others, during his employment with the Company that are (i) made with the firm’s equipment, supplies, facilities, trade secrets, or time; or
(ii) that relate, at the time of conception or reduction to practice to the Company’s business, to the Company’s actual or demonstrably anticipated research; or (iii) result from any work performed by Employee for the Company,

Employee agrees that any inventions, products, processes, apparatus, designs, improvements, or business related suggestions and information,

consider necessary to carry out this Agreement, including domestic and foreign patent applications prepared at the expense of the Company and formal assignments to the Company of all rights in such inventions and patent applications and the patents
issued thereon together with all divisions, continuations, and reissues thereof. Employee further agrees to submit to a reasonable and confidential review process under which the Company may determine any issues as may arise under the provisions of
this paragraph. 
 Employee represents that he has no unpatented inventions which are to be withheld from this Agreement except those listed

addition to all of the Company’s rights and remedies under this Agreement and available under applicable law, including but not limited to, the right of the recovery of monetary damages and all other forms of other relief including, without
limitation, equitable relief, from Employee, the Company shall be entitled to seek issuance by any court of competent jurisdiction of temporary, preliminary and permanent injunctions enjoining any such breach or threatened breach by Employee.

or without cause. In the event of such a voluntary termination by Employee (other than for Good Reason (as defined below)), the Company requests Employee to provide written notice of termination at least thirty (30) days prior to the effective
date of his termination. The Company shall, in such event, remain free to accept such notice and continue Employee’s employment up to the effective date of termination, or to pay Employee thirty (30) days’ pay in lieu of accepting
notice and require his immediate termination. In the event Employee terminates his own employment (other than for Good Reason), Employee shall be entitled only to that compensation and those benefits earned by and vested in him as of the effective

employment with the Company for Good Reason upon prior written notice to the Company setting forth in reasonable detail the nature of the Good Reason. The following shall constitute “Good Reason”: without Employee’s written consent,
(i) the failure of the Company to make any payment that it is required to make hereunder to Employee when such payment is due; (ii) the assignment to Employee of duties materially inconsistent with Employee’s position and status with
the Company, a change in Employee’s title, or a material reduction in Employee’s responsibilities; (iii) a reassignment of Employee’s primary work location outside of San Bernardino County, CA or (iv) the Company’s
breach of any material provision of this Agreement; provided, however, that such conduct shall not constitute Good Reason unless and until Employee has provided the Company with written notice setting forth in reasonable detail the nature of the
Good Reason and the Company has not cured such conduct within thirty (30) days after receipt of such notice. 
 The Company is and
remains free to terminate Employee’s employment at any time, for any reason, with or without cause. 
 In the event of a termination by
the Company without cause, the Company shall provide Employee with thirty (30) days’ notice of termination and Employee shall continue to receive through Employee’s employment with the Company the compensation and benefits to which he
is entitled under this Agreement. The Company may, in lieu of thirty (30) days’ notice, pay Employee one month’s salary with an immediate termination.

 Additionally, in the event of a termination by Company without cause or by Employee for Good
Reason, in exchange for Employee signing (and non-revocation of) a general release of claims that is effective within sixty (60) days of termination in a form to be provided by the Company promptly
following the termination, (i) the Company shall provide Employee with six (6) month’s base salary which amount shall be paid in substantially equal installments, in accordance with regular payroll practices, over such 6-month period; provided, that in the event Employee breaches any of paragraphs (C) — (J) of Section II hereof, all such payments shall immediately cease, in each instance only after a written demand to cure
such breach is delivered to Employee setting forth in reasonable detail the circumstances of such breach and Employee fails to cure such breach (if it reasonably can be cured) within the ten (10) day period following his receipt of such written
notice and (ii) any of Employee’s non-vested IEA shall immediately vest and not be subject to forfeiture. 

In the event of a termination for cause, as defined below, no notice of termination shall be required and Employee will not be entitled to any
further compensation or benefits. In the event of a termination for cause, Employee shall be entitled only to that compensation and those benefits earned by and vested in him as of the effective date of such termination, calculated on a pro-rated basis. 
 Termination may be effected for cause, as follows:

only after a written demand to cure such breach is delivered to Employee setting forth in reasonable detail the circumstances of such breach and Employee fails to cure such breach (if it reasonably can be cured) within the thirty (30) day
period following his receipt of such written notice; 


  

	 	•	 	 Any material act of dishonesty, or any act of misappropriation, embezzlement, fraud or similar conduct involving
the Company or any of its affiliates; 


  

	 	•	 	 Employee’s continued willful failure or refusal to perform Employee’s material duties or
responsibilities after a written demand to cure such failure or refusal is delivered to Employee setting forth in reasonable detail the circumstances of such failure or refusal and Employee fails to cure such failure or refusal within the ten
(10) day period following his receipt of such written notice; 


  

	 	•	 	 The conviction of or the plea of guilty or nolo contendere or the equivalent by Employee of a felony or other

or business of the Company; or 


  

	 	•	 	 Employee’s engagement in illegal conduct, gross negligence or willful misconduct which is, or could be

subsidiaries. 
  

	IV.	 COMPENSATION AND BENEFITS OF EMPLOYEE 



 

	 	A.	 Annual Compensation 



1.    During Employee’s employment hereunder, Employee shall be provided an annual salary. From July 1, 2020 to
December 31, 2020, such annual salary shall be at the rate of $250,000 per year (about $25,000 per month), less applicable payroll deductions. Thereafter, Employee’s salary shall be determined by the Board of Managers (or compensation
committee thereof) in consultation with Employee but in no event shall be less than $250,000 per year. Payment of Employee’s salary shall be made in accordance with the Company’s periodic payroll practices. 

2.    In addition to base salary, Employee shall be eligible to receive an annual incentive compensation award, with the
actual value of the annual incentive compensation award with respect to any year being based upon the level of achievement of annual Company and individual performance objectives for such year, as determined by the Board of Managers (or compensation
committee thereof), which may include objectives relating to plant Safety, recovery/efficiency, and economic success. For 2020, the target annual incentive compensation award will be $450,000, with actual payment being between 0% and 150% of target,
depending on level of performance. The annual incentive compensation award shall be paid to Employee at the same time as annual bonuses are generally payable to other senior executives of the Company (provided, that in all events the annual
incentive shall be paid in the year following the year for which the annual incentive applies) subject to Employee’s continuous employment through the end of the relevant year to which the bonus applies. 

 

	 	B.	 Initial Equity Award 



1.    Subject to Employee’s continued employment through the Transition Date, Employee will be granted an Initial
Equity Award (“IEA”) in the form of restricted common stock of the PubCo having a value1 equal to 1.7% of the pre-money Combined Company Equity
Value (as defined below). The IEA shall be granted on or as soon as practicable following the Transition Date, such grant to be subject to the closing of the Going Public Transaction. The IEA shall be made in the form of a grant under the PubCo
equity compensation plan, pursuant to an award agreement with customary terms reasonably acceptable to the Company and Employee, including without limitation, provisions to allow for the sale of restricted stock or other customary mechanism so that
on vesting any tax liabilities which may arise solely from the vesting of the IEA may be paid by Employee (the “PubCo Plan and Award Agreement”), and the shares comprising the IEA shall be registered under the Securities Act of 1933, as
amended. If applicable 

	 	 



 

	1 	 For purposes of this Agreement, the number of shares which will be issued based on the Company’s value
shall be determined using the per share price of the IPO or the value of a PubCo share used to determine the merger consideration per share. 



  
 9 














          

EXECUTION COPY 
  

 
law or stock exchange rule does not permit the grant of the IEA as contemplated by this Agreement, the Company and Employee shall negotiate in good faith to enter into a cash-based award
agreement providing comparable value to Employee. For purposes of ensuring clarity, “Combined Company Equity Value” is defined as the aggregate value of the equity of the Company, the equity of Secure Natural Resources LLC
(“SNR”) and/or the equity of the Company’s and SNR’s successors, which in the event of a Going Public Transaction shall be the “Equity Value” as determined by the definitive documentation of such transaction and
disregarding any other compensatory equity awards made at or contemporaneously with the Closing. 
 2.    The IEA shall
vest over four years as follows: 40% on the date that is 15 months after the grant date, 20% on the date that is 27 months after the grant date, 20% on the date that is 39 months after the grant date, and 20% on the fourth anniversary of the grant
date; provided that the IEA will fully vest on a Change of Control of PubCo. “Change of Control” is defined as (i) a merger in which PubCo is not the surviving corporation; (ii) a merger, sale or transaction involving PubCo where
the equity holders of PubCo before such merger or sale or exchange do not retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock of the surviving corporation or the parent company thereof; or
(iii) the sale or exchange of all or substantially all of PubCo’s assets; provided, however, that the definition of Change of Control may be superseded by any comparable definition in the PubCo Plan and Award Agreement. In the event, that
Employee is terminated by Company without cause or by Employee for Good Reason or due to his death or disability (as defined below), he shall fully vest in all non-vested IEA (subject to execution of the
release contemplated in Section III. above in the case of a termination without cause or by Employee for Good Reason); provided, however, that the definition of disability may be superseded by any comparable definition in the PubCo Plan and Award
Agreement. For purposes of this section, “disability” shall mean Employee’s inability to perform his duties as set forth in Section II.A above as a result of any medically determinable physical or mental impairment for a period of 90
consecutive days, or for a period of 120 non-consecutive days in any one year period. Company will work in good faith with Employee to determine the most tax efficient structure for the issuance of the IEA.

  

	 	C.	 Paid Vacation 



During the term of this Agreement, Employee is eligible to receive or accrue paid vacation in accordance with the Company’s policies
applicable to employees in positions similar or comparable to Employee’s. Specifically, Employee shall be entitled to four weeks of vacation annually. 
  

	 	D.	 Holidays 



Employee shall be entitled to those paid holidays observed by the Company. Specific holidays are determined by and in the discretion of the
Company yearly, and are published no later than January of each year.

laws provisions. If any legal action or other proceeding is brought by any party for the enforcement of this Agreement, or because of any alleged dispute, breach or default in connection with any provisions of this Agreement, such action shall be
brought exclusively in state or federal court of New York, and the parties agree to the jurisdiction thereof; provided, however, if said court shall decline jurisdiction or decline to afford injunctive relief to the Company on account of the breach
or threatened breach of this Agreement by Employee, the Company shall be entitled to seek such relief from any other court of competent jurisdiction, wherever located. Employee recognizes that, should any dispute or controversy arising from or
relating to this Agreement be submitted for adjudication to any court, arbitration panel or other third party, the preservation of the secrecy of Confidential Information and Trade Secrets may be jeopardized. Consequently, Employee agrees that all
issues of fact shall be tried without a jury. 
  

	 	H.	 Indemnification 



The Company shall indemnify Employee to the maximum extent permitted by law in respect of any claim, investigation, suit or dispute brought
against Employee because Employee serves as an officer of the Company or any of its subsidiaries, and the Company agrees to advance Employee’s reasonable expenses incurred therewith upon Employee executing an undertaking agreeing to repay any
such advances if Employee is ultimately found not to have been entitled to such indemnification. The Company shall not be obligated to indemnify Employee if a court of competent jurisdiction finds Employee’s conduct to have constituted gross
negligence, willful misconduct, fraud, or criminal conduct in performing or failing to perform any duties and responsibilities under this Agreement. 
  

	 	I.	 Counterparts 



This Agreement may be executed in two or more counterparts, each of which shall be an original and all of which together shall constitute one
and the same instrument.

	 	J.	 409A 



1.    General. The payments and benefits provided hereunder are intended to be exempt from or compliant with the
requirements of Section 409A of the Code. Notwithstanding any provision of this Agreement to the contrary, in the event that the Company reasonably determines that any payments or benefits hereunder are not either exempt from or compliant with
the requirements of Section 409A of the Code, the Company shall have the right to adopt such amendments to this Agreement or adopt such other policies and procedures (including amendments, policies and procedures with retroactive effect), or
take any other actions, that are necessary or appropriate (i) to preserve the intended tax treatment of the payments and benefits provided hereunder, to preserve the economic benefits with respect to such payments and benefits, and/or
(ii) to exempt such payments and benefits from Section 409A of the Code or to comply with the requirements of Section 409A of the Code and thereby avoid the application of penalty taxes thereunder; provided, however, that this does
not, and shall not be construed so as to, create any obligation on the part of the Company to adopt any such amendments, policies or procedures or to take any other such actions or to indemnify the Employee for any failure to do so. 

2.    Exceptions to Apply. The Company shall apply the exceptions provided in Treasury Regulation Section 1.409A-1(b)(4), Treasury Regulation Section 1.409A-1(b)(9) and all other applicable exceptions or provisions of Code Section 409A to the payments and
benefits provided under this Agreement so that, to the maximum extent possible such payments and benefits are not deemed to be “nonqualified deferred compensation” subject to Code Section 409A. All payments and benefits provided under
this Agreement shall be deemed to be separate payments (and any payments made in installments shall be deemed a series of separate payments) for purposes of Code Section 409A. 

3.    Taxable Reimbursements. To the extent that any payments or reimbursements provided to the Employee in the
course of his employment are deemed to constitute “nonqualified deferred compensation” subject to Code Section 409A, such amounts shall be paid or reimbursed reasonably promptly, but not later than December 31 of the year
following the year in which the expense was incurred. The amount of any payments or expense reimbursements that constitute compensation in one year shall not affect the amount of payments or expense reimbursements constituting compensation that are
eligible for payment or reimbursement in any subsequent year, and the Employee’s right to such payments or reimbursement of any such expenses shall not be subject to liquidation or exchange for any other benefit. 

4.    Specified Executive. Notwithstanding anything to the contrary in this Agreement, no compensation or benefits
that are “nonqualified deferred compensation” subject to Code Section 409A shall be paid to Employee during the 6-month period following his separation from service to the extent that the
Company determines that the Employee is a “specified employee” and that paying such amounts at the time or times indicated in this Agreement would be a prohibited distribution under Code Section 409A(a)(2)(B)(i). If the payment of any
such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such 6-month period (or such earlier date upon which such amount can be paid under Code
Section 409A without being subject to such additional taxes, including as a result of the Employee’s death), the Company shall pay to the Employee a lump-sum amount equal to the cumulative amount
that would have otherwise been payable to the Employee during such 6-month period.
