Exhibit 10.6


 


EXECUTIVE EMPLOYMENT AGREEMENT


 


This EXECUTIVE EMPLOYMENT AGREEMENT (“Agreement”)
is made and entered into as of the 4th day of October, 2021 by and between PDS-Photonica Holdings (Guernsey) Ltd., a Guernsey corporation
headquartered at Anson Court, La Route des Camps, St. Martin, Guernsey, GY4 6AD (“Company”) and Paul Mann, an individual
(“Executive”). The Company is a wholly owned subsidiary of ASP Isotopes Inc, a Delaware corporation headquartered at
433 Plaza Real, Suite 275, Boca Raton, Florida. 33432 (“Parent”). As used herein, the “Effective Date”
of this Agreement shall mean the date as written above and signed below.


 


W I T N E S S E T H:


 


WHEREAS, the Executive
desires to be employed by the Company as its Chief Executive Officer and its Chief Financial Officer and the Company wishes to employ
the Executive in such capacities, in each case, commencing on and as of the Effective Date.


 


NOW, THEREFORE,
in consideration of the foregoing and their respective covenants and agreements contained in this document, the Company and the Executive
hereby agree as follows:


 


1. Employment
and Duties. The Company agrees to employ and the Executive agrees to serve as the Company’s Chief Executive Officer and Chief
Financial Officer. In this capacity the Executive shall have such duties, authorities and responsibilities commensurate with the duties,
authorities and responsibilities customary to these positions and such other duties and responsibilities as the Company’s and the
Parent’s Boards of Directors (“Board”) may from time to time assign to the Executive. The parties expect the
Executive to voluntarily resign one of these positions at some point in the future when a qualified replacement is appointed by the Board.
At that time, Executive’s title and duties and responsibilities hereunder will automatically revert to those of his then-continuing
position.


 


The Executive shall devote the
majority of his time, efforts and services to the business and affairs of the Company, its Parent, and their respective subsidiaries.
Nothing in this Section 1 shall prohibit the Executive from: (A) serving as a director or member of any other board, committee thereof
of any other entity or organization; (B) delivering lectures, fulfilling speaking engagements, and any writing or publication relating
to his area of expertise; (C) serving as a director or trustee of any governmental, charitable or educational organization; (D) engaging
in additional activities in connection with personal investments and community affairs, including, without limitation, professional or
charitable or similar organization committees, boards, memberships or similar associations or affiliations, or (E) performing consulting
and advisory activities, provided, however, such activities are not in competition with the business and affairs of the
Parent or would tend to cast executive of Parent in a negative light in the reasonable judgment of the Board.


 


At any time, and at the Executive’s
sole discretion, the Executive retains the right to become an employee of the Parent under an agreement substantially similar to this
Agreement.


 


2. Term.
The term of this Agreement shall commence on the Effective Date and shall continue for a period of three (3) years following the Effective
Date and shall be automatically renewed for successive one (1) year periods thereafter unless either party provides the other party with
written notice of his or its intention not to renew this Agreement at least three (3) months prior to the expiration of the initial term
or any renewal term of this Agreement. “Employment Period” shall mean the initial three (3)-year term plus one (1)-year
renewals, if any.


 


3. Place of
Employment. The Executive’s services shall be performed at such location or locations as the Executive shall determine, in
his sole discretion. The Executive’s services shall be performed principally at his personal residence, subject to any
required business travel.


 


4. Base
Salary and Board Fees. The Company agrees to pay the Executive a base salary (“Base Salary”) of $240,000 per annum
for the first six (6) months and $480,000 per annum for the remainder of the Employment Period for the position(s) of either Chief Executive
Officer or Chief Financial Officer or both positions. It is anticipated that at some point in the future the Executive will drop one role
and continue with the other. The Base Salary will not be adjusted if the Executive holds both positions or just a single position. Annual
adjustments after the first year of the Employment Period shall be determined by the Board; provided, however, that the
Base Salary may not be decreased. The Base Salary shall be paid in periodic installments in accordance with the Company’s regular
payroll practices. Executive shall, subject to policies and procedures of the Parent’s Board of Directors, be eligible to additional
fees for service on the Board.






    	 	 	 



     


    

 


5. Incentive
Compensation and Bonuses.


 


(a) Annual
Bonus: For each fiscal year during the term of employment, the Executive shall be eligible
to receive a bonus in the target amount of 100% of annual salary (the “Annual Bonus”), with the amount of such bonus
determined from time to time by the Board in its discretion. The Annual Bonus shall be paid by the Company to the Executive promptly
after determination that the relevant targets, if any, have been met, it being understood that the attainment of any financial targets
associated with any bonus shall not be determined until following the completion of the Parent’s annual audit and public announcement
of such results and shall be paid promptly following the Parent’s announcement of earnings. In the event that the Compensation Committee
is unable to act or if there shall be no such Compensation Committee, then all references herein to the Compensation Committee (except
in the proviso to this sentence) shall be deemed to be references to the Board. Upon his termination from employment, the Executive shall
be entitled to receive a pro-rated Annual Bonus calculated based on his final day of employment, regardless of whether he is employed
by the Company through the conclusion of the fiscal quarter or year, as the case may be, on which the Annual Bonus is based. Annual Bonus’s
will be paid in a mixture of Cash and Common Stock, the ratio of which will be determined by the Compensation Committee. The number of
shares granted in the Common Stock portion of the Annual Bonus shall be determined by dividing the value of the Common Stock portion of
the Annual Bonus by either (i) the fair market value per share of Common Stock, as determined in good faith by the Board, or (ii) the
closing sale price of the Common Stock on the trading day immediately preceding the applicable Payment Date, as reported by the principal
trading market for the Common Stock.


 


(b) Milestone
Based Bonuses: The Executive will also be entitled to milestone-based bonuses which will be paid in shares of common stock. These
will be driven by the achievement of revenue milestones which will be defined as the trailing three-month average revenues achieved by
the Parent. For the purpose of this Agreement revenues will follow the definition of revenues as defined by US GAAP and will exclude any
one-off sales, lump-sum contracts, sale of equipment and revenues related to M&A. At the achievement of $4.167 million in average
monthly revenues for the trailing three months the Executive will be awarded a $1 million bonus. At the achievement of $8.33 million in
average monthly revenues for the trailing three months the Executive will be awarded a $1 million bonus. At the achievement of $12.5 million
in average monthly revenues for the trailing three months the Executive will be awarded a $1 million bonus. At the achievement of $16.67
million in average monthly revenues for the trailing three months the Executive will be awarded a $1 million bonus. These milestone-based
bonuses will be paid within 30 days of the achievement and will not alter of effect the Annual Bonus described in Section 5(a). The number
of shares granted in the Milestone Based Bonus shall be determined by dividing $1 million by either (i) the fair market value per share
of Common Stock, as determined in good faith by the Board, or (ii) the closing sale price of the Common Stock on the trading day immediately
preceding the applicable Payment Date, as reported by the principal trading market for the Common Stock.


 


(c) Equity
Awards and Incentive Compensation: During the term of employment, the Executive shall be eligible to participate in any equity-based
incentive compensation plan or program adopted by either the Parent or the Company (such awards under such plan or program, the “Share
Awards”) as the Compensation Committee or Board may from time to time determine. Share Awards shall be subject to applicable plan
terms and conditions. And any additional terms and conditions as determined by the Compensation Committee or the Board.


 


6. Severance
Compensation:


 


Upon termination of employment
for any reason other than the Executive’s voluntary resignation pursuant to Section 10(e), the Executive shall receive his Accrued
Benefits (as defined in Section 10(e)) and will also be entitled to: (A) continuation of the Executive’s Base Salary from the date
immediately following the termination date until the end of the then-applicable Employment Period, payable according to Section 4; and
(B) all Share Awards earned and vested prior to termination. With respect to any Share Awards held by the Executive as of his death, Disability,
termination without Cause, or resignation for Good Reason, that are not vested and exercisable as of such date, the Parent and/or the
Company shall fully accelerate the vesting and exercisability of such Share Awards, so that all such Share Awards shall be fully vested
and exercisable as of the Executive’s termination, such options (as well as any Share Awards that previously became vested and exercisable)
to remain exercisable, notwithstanding anything in any other agreement governing such options, until the earlier of (X) a period of one
(1) year after the Executive’s termination or (Y) the original term of the option, if such Share Awards is an option.


 






    	 	2	 



     


    

 


The Executive may continue coverage
with respect to the Parent’s group health plans as permitted by the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”)
for himself and each of his “Qualified Beneficiaries” as defined by COBRA (“COBRA Coverage”). Upon
the Executive’s termination of employment for any reason other than Executive’s voluntary resignation pursuant to Section
10(e), the Parent shall reimburse the amount of any COBRA premium paid for COBRA Coverage timely elected by and for the Executive and
any Qualified Beneficiary of the Executive, and not otherwise reimbursed, during the period that ends on the earliest of (x) the date
the Executive or the Qualified Beneficiary, as the case may be, ceases to be eligible for COBRA Coverage, (y) the last day of the consecutive
eighteen (18) month period following the date of the Executive’s termination of employment and (z) the date the Executive or the
Qualified Beneficiary, as the case may be, is covered by another group health plan. To reimburse any COBRA premium payment under this
paragraph, the Parent must receive documentation of the COBRA premium payment within ninety (90) days of its payment.


 


7. Expenses.
The Executive shall be entitled to prompt reimbursement by the Parent for all reasonable ordinary and necessary travel, entertainment,
and other expenses incurred by the Executive while employed (in accordance with the policies and procedures established by the Parent
for its senior executive officers) in the performance of his duties and responsibilities under this Agreement; provided, that the Executive
shall properly account for such expenses in accordance with Parent policies and procedures.


 


8. Other
Benefits. During the term of this Agreement, the Executive shall be eligible to participate in incentive, stock purchase, savings,
retirement (401(k)), and welfare benefit plans, including, without limitation, health, medical, dental, vision, life (including accidental
death and dismemberment) and disability insurance plans (collectively, “Benefit Plans”), in substantially the same
manner and at substantially the same levels as the Parent makes such opportunities available to the Parent’s managerial or salaried
executive employees and/or its senior executives.


 


The Parent shall pay one hundred
percent (100%) of the cost for any group medical, vision and/or dental coverage elected by and for the Executive and one hundred (100%)
of the additional incremental cost for any group medical, vision and/or dental coverage elected by the Executive for the Executive’s
family. Notwithstanding the foregoing, to the extent payment of such cost will result in a violation of the nondiscrimination rules of
Section 105(h)(2) of the Internal Revenue Code of 1986, as amended (the “Code”), or any statute or regulation of similar
effect, then the parties shall negotiate in good faith an alternative arrangement that places the Executive in substantially the same
after-tax position.


 


The Executive shall be entitled
to air travel, including travel by business and/or first class, as is reasonable and necessary for the performance of his duties and responsibilities,
in accordance with the Parent’s policies as approved by the Board.


 


9. Vacation.
During the term of this Agreement, the Executive shall be entitled to accrue, on a pro rata basis, forty (40) paid vacation days per year.
Vacation shall be taken at such times as are mutually convenient to the Executive and the Parent and no more than ten (10) consecutive
days shall be taken at any one time without Parent approval in advance.


 


10. Termination
of Employment:


 


(a) Death.
If the Executive dies during the Employment Period, this Agreement and the Executive’s employment with the Company shall automatically
terminate and the Company’s obligations to the Executive’s estate and to the Executive’s Qualified Beneficiaries shall
be those set forth in Section 6 regarding severance compensation.


 


(b) Disability.
In the event that, during the term of this Agreement the Executive shall be prevented from performing his essential functions hereunder
to the full extent required by the Company by reason of Disability (as defined below), this Agreement and the Executive’s employment
with the Company shall automatically terminate. The Company’s obligation to the Executive under such circumstances shall be those
set forth in Section 6 regarding severance compensation. For purposes of this Agreement, “Disability” shall mean a
physical or mental disability that prevents the performance by the Executive, with or without reasonable accommodation, of his essential
functions hereunder for an aggregate of ninety (90) days or longer during any twelve (12) consecutive months. The determination of the
Executive’s Disability shall be made by an independent physician who is reasonably acceptable to the Company and the Executive (or
his representative), be final and binding on the parties hereto and be made taking into account such competent medical evidence as shall
be presented to such independent physician by the Executive and/or the Company or by any physician or group of physicians or other competent
medical experts employed by the Executive and/or the Company to advise such independent physician.


 






    	 	3	 



     


    

 


(c) Cause.


 


(i) At
any time during the Employment Period, the Parent may terminate this Agreement and the Executive’s employment hereunder for Cause.
For purposes of this Agreement, “Cause” shall mean: (a) the willful and continued failure of the Executive to perform
substantially his duties and responsibilities for the Company (other than any such failure resulting from the Executive’s death,
Disability, or approved leave-of-absence) after a written demand by the Board for substantial performance is delivered to the Executive
by the Parent, which specifically identifies the manner in which the Board believes that the Executive has not substantially performed
his duties and responsibilities, which willful and continued failure is not cured by the Executive within thirty (30) days following his
receipt of such written demand; (b) the conviction of, or plea of guilty or nolo contendere to, a felony, or (c) fraud, dishonesty
or gross misconduct which is materially and demonstratively injurious to the Parent. Termination under clauses (b) or (c) of this Section
10(c)(1) shall not be subject to cure.


 


(ii) For
purposes of this Section 10(c), no act, or failure to act, on the part of the Executive shall be considered “willful” unless
done, or omitted to be done, by him in bad faith and without reasonable belief that his action or omission was in, or not opposed to,
the best interest of the Parent. Between the time the Executive receives written demand regarding substantial performance, as set forth
in subparagraph (1) above, and prior to an actual termination for Cause, the Executive will be entitled to appear (with counsel) before
the full Board to present information regarding his views on the Cause event. After such hearing, termination for Cause must be approved
by a majority vote of the full Board (other than the Executive). After providing the written demand regarding substantial performance,
the Board may suspend the Executive with full pay and benefits until a final determination by the full Board has been made.


 


(iii) Upon
termination of this Agreement for Cause, the Company shall have no further obligations or liability to the Executive or his heirs, administrators
or executors with respect to compensation and benefits thereafter, except for the obligation to pay the Executive any Base Salary earned
through the date of termination to be paid according to Section 4; any unpaid Annual Bonus to be paid according to Section 5; reimbursement
of any and all reasonable expenses paid or incurred by the Executive in connection with and related to the performance of his duties and
responsibilities for the Parent and the Company during the period ending on the termination date to be paid according to Section 7; and
any accrued but unused vacation time through the termination date in accordance with Parent policy. The Parent shall deduct, from all
payments made hereunder, all applicable taxes, including income tax, FICA and FUTA, and other appropriate deductions.


 


(d) For
Good Reason or a Change of Control or Without Cause.


 


(i) At
any time during the term of this Agreement and subject to the conditions set forth in Section 10(d)(ii) below the Executive may terminate
this Agreement and the Executive’s employment with the Company for “Good Reason” or for a “Change of Control”
(as defined in Section 10(f)). For purposes of this Agreement, “Good Reason” shall mean the occurrence of any of the following
events without Executive’s consent: (A) the assignment to the Executive of duties that are significantly different from, and/or
that result in a substantial diminution of, the duties that he assumed on the Effective Date (including reporting to anyone other than
solely and directly to the Board); (B) the assignment to the Executive of a title that is different from and subordinate to the title
of, as applicable, either Chief Executive Officer or Chief Financial Officer of the Company; provided, however, for the
absence of doubt following a Change of Control, should the Executive be required to serve in a diminished capacity in a division or unit
of another entity (including the acquiring entity), such event shall constitute Good Reason regardless of the title of the Executive in
such acquiring company, division or unit; (C) a material reduction in Executive’s Base Salary or total annual cash compensation
opportunity; or (D) material breach by the Company of this Agreement.


 


(ii) The
Executive shall not be entitled to terminate this Agreement for Good Reason unless and until he shall have delivered written notice to
the Parent within ninety (90) days of the date upon which the facts giving rise to Good Reason occurred of his intention to terminate
this Agreement and his employment with the Company for Good Reason, which notice specifies in reasonable detail the circumstances claimed
to provide the basis for such termination for Good Reason, and the Parent shall not have eliminated the circumstances constituting Good
Reason within thirty (30) days of its receipt from the Executive of such written notice. In the event the Executive elects to terminate
this Agreement for Good Reason in accordance with Section 10(d)(i), such election must be made within the twenty-four (24) months following
the initial existence of one or more of the conditions constituting Good Reason as provided in Section 10(d)(i). In the event the Executive
elects to terminate this Agreement for a Change in Control in accordance with Section 10(d)(i), such election must be made within one
hundred eighty (180) days of the occurrence of the Change of Control.

(iii) In
the event that the Executive terminates this Agreement and his employment with the Company for Good Reason or for a Change of Control
or the Parent terminates this Agreement and the Executive’s employment with the Company without Cause, the Company shall pay or
provide to the Executive (or, following his death, to the Executive’s heirs, administrators or executors) the severance compensation
set forth in Section 6 above. The Company shall deduct, from all payments made hereunder, all applicable taxes, including income tax,
FICA and FUTA, and other appropriate deductions.


 


(iv) The
Executive shall not be required to mitigate the amount of any payment provided for in this Section 10(d) by seeking other employment or
otherwise, nor shall the amount of any payment provided for in this Section 10(d) be reduced by any compensation earned by the Executive
as the result of employment by another employer or business or by profits earned by the Executive from any other source at any time before
and after the termination date. The Company’s obligation to make any payment pursuant to, and otherwise to perform its obligations
under, this Agreement shall not be affected by any offset, counterclaim or other right that the Parent may have against the Executive
for any reason.


 


(e) Without
“Good Reason” by the Executive. At any time during the term of this Agreement, the Executive shall be entitled to terminate
this Agreement and the Executive’s employment with the Company without Good Reason and other than for a Change of Control by providing
prior written notice of at least thirty (30) days to the Parent. Upon termination by the Executive of this Agreement or the Executive’s
employment with the Company without Good Reason and other than for a Change of Control, the Company shall have no further obligations
or liability to the Executive or his heirs, administrators or executors with respect to compensation and benefits thereafter, except for
the obligation to pay the Executive the following (collectively, the “Accrued Benefits”): (i) any Base Salary earned
through the date of termination to be paid according to Section 4; (ii) any earned but unpaid Annual Bonus to be paid according to Section
5(a); (iii) Executive’s pro-rated Annual Bous for the year of termination to be paid according to Section 5(a); (iv) reimbursement
of any and all reasonable expenses paid or incurred by the Executive in connection with and related to the performance of his duties and
responsibilities for the Company during the period ending on the termination date to be paid according to Section 7; (v) any accrued but
unused vacation time through the termination date in accordance with Company policy; (vi) any accrued and vested benefits under the Benefit
Plans; and (vii) all Share Awards earned and vested as of the date or termination. The Company shall deduct, from all payments made hereunder,
all applicable taxes, including income tax, FICA and FUTA, and other appropriate deductions.


 


(f) Change
of Control. For purposes of this Agreement, “Change of Control” shall mean the occurrence of any one or more of the following:
(i) the accumulation (if over time, in any consecutive twelve (12) month period), whether directly, indirectly, beneficially or of record,
by any individual, entity or group (within the meaning of Section 12(d)(3) or 13(d)(2) of the Securities Exchange Act of 1934, as amended)
of fifty percent (50%) or more of the shares of the outstanding Common Stock of the Parent, whether by merger, consolidation, sale or
other transfer of shares of Common Stock (other than a merger or consolidation where the stockholders of the Parent prior to the merger
or consolidation are the holders of a majority of the voting securities of the entity that survives such merger or consolidation), (ii)
a sale of all or substantially all of the assets of the Parent or (iii) during any period of twelve (12) consecutive months, the individuals
who, at the beginning of such period, constitute the Board, and any new director whose election by the Board or nomination for election
by the Parent’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either
were directors at the beginning of the twelve (12) month period or whose election or nomination for election was previously so approved,
cease for any reason to constitute at least a majority of the Board; provided that the following acquisitions shall not constitute a Change
of Control for the purposes of this Agreement: any acquisition of Common Stock or securities convertible into Common Stock by any employee
benefit plan (or related trust) sponsored by or maintained by the Parent.


 


(g) Notice
of Termination. Any termination of the Executive’s employment by the Company or by the Executive (other than termination by
reason of the Executive’s death) shall be communicated by written Notice of Termination to the other party of this Agreement. For
purposes of this Agreement, a “Notice of Termination” shall mean a written notice which shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide
a basis for termination of the Executive’s employment under the provision so indicated, provided, however, failure to provide timely
notification shall not affect the employment status of the Executive.

11. Confidential
Information.


 


(a) Disclosure
of Confidential Information. The Executive recognizes, acknowledges and agrees that he has had and will continue to have access to
secret and confidential information regarding the Parent, the Company, their respective subsidiaries and their respective businesses (collectively,
the “Parent Group”), including but not limited to, the Parent Group’s products, methods, formulas, software code, patents,
sources of supply, customer dealings, data, know-how, trade secrets and business plans (“Confidential Information”), provided
such information is not in or does not hereafter become part of the public domain, or become known to others through no fault of the Executive.
The Executive acknowledges that such information is of great value to the Parent Group, is the sole property of the Parent Group, and
has been and will be acquired by him in confidence. In consideration of the obligations undertaken by the Parent herein, the Executive
will not, at any time, during or after his employment hereunder, reveal, divulge or make known to any person, any information acquired
by the Executive during the course of his employment, which is treated as confidential by the Parent Group, and not otherwise in the public
domain. The provisions of this Section 11 shall survive the termination of the Executive’s employment hereunder. The Executive affirms
that he does not possess and will not rely upon the protected trade secrets or confidential or proprietary information of any prior employer(s)
in providing services to the Parent Group.


 


(b) Return
of Confidential Information. In the event that the Executive’s employment with the Parent terminates for any reason, the Executive
shall deliver forthwith to the Parent any and all originals and copies, including those in electronic or digital formats, of Confidential
Information; provided, however, the Executive shall be entitled to retain (i) papers and other materials of a personal nature,
including, but not limited to, photographs, correspondence, personal diaries, calendars and rolodexes, personal files and phone books,
(ii) information showing his compensation or relating to reimbursement of expenses, (iii) information that he reasonably believes may
be needed for tax purposes and (iv) copies of plans, programs and agreements relating to his employment, or termination thereof, with
the Parent. The covenants and agreements in this Section 11 shall exclude excludes information (A) which is in the public domain through
no unauthorized act or omission of Executive or (B) which becomes available to Executive on a non-confidential basis from a source other
than a member of the Parent Group without breach of such source’s confidentiality or non-disclosure obligations to the Parent Group.


 


12. Non-Competition
and Non-Solicitation.


 


(a) The
Executive agrees and acknowledges that the Confidential Information that the Executive has already received and will receive is valuable
to the Parent Group and that its protection and maintenance constitutes a legitimate business interest of the Parent Group, to be protected
by the non-competition restrictions set forth herein. The Executive agrees and acknowledges that the non-competition restrictions set
forth herein are reasonable and necessary and do not impose undue hardship or burdens on the Executive. The Executive also acknowledges
that the Parent Group’s Business (as defined in Section 12(b)(1) below) is conducted worldwide (the “Territory”), and
that the Territory, scope of prohibited competition, and time duration set forth in the non-competition restrictions set forth below are
reasonable and necessary to maintain the value of the Confidential Information of, and to protect the goodwill and other legitimate business
interests of, any member of the Parent Group and/or such member’s clients or customers. The provisions of this Section 12 shall
survive the termination of the Executive’s employment hereunder for the time periods specified below.


 


(b) The
Executive hereby agrees and covenants that he shall not without the prior written consent of the Board, directly or indirectly, in any
capacity whatsoever, including, without limitation, as an employee, employer, consultant, principal, partner, shareholder, officer, director
or any other individual or representative capacity (other than (i) as a holder of less than two (2%) percent of the outstanding securities
of a company whose shares are traded on any national securities exchange or (ii) as a limited partner, passive minority interest holder
in a venture capital fund, private equity fund or similar investment entity which holds or may hold an equity or debt position in portfolio
companies that are competitive with the Parent; provided, however, that the Executive shall be precluded from serving as
an operating partner, general partner, manager or governing board designee with respect to such portfolio companies), or whether on the
Executive’s own behalf or on behalf of any other person or entity or otherwise howsoever, during the Term and thereafter to the
extent described below, within the Territory:


 


(i) Engage,
own, manage, operate, control, be employed by, consult for, participate in, or be connected in any manner with the ownership, management,
operation or control of any business in competition with the Business of the Parent, as defined in the next sentence. For purposes hereof,
the Parent Group’s “Business” shall mean research, development, techniques and technology in any manner involving or
related to the separation of isotopes;


 






    	 	6	 



     


    

 


(ii) Recruit,
solicit or hire, or attempt to recruit, solicit or hire, any employee, or independent contractor of the Parent Group to leave the employment
(or independent contractor relationship) thereof, whether or not any such employee or independent contractor is party to an employment
agreement, for the purpose of competing with the Business of the Parent Group;


 


(iii) Attempt
in any manner to solicit or accept from any customer of the Parent Group, with whom Executive had significant contact during Executive’s
employment by the Parent Group (whether under this Agreement or otherwise), business of the kind or competitive with the business done
by the Parent Group with such customer or to persuade or attempt to persuade any such customer to cease to do business or to reduce the
amount of business which such customer has customarily done or might do with the Parent Group, or if any such customer elects to move
its business to a person other than the Parent Group, provide any services of the kind or competitive with the business of the Parent
Group for such customer, or have any discussions regarding any such service with such customer, on behalf of such other person for the
purpose of competing with the Business of the Parent Group; or


 


(iv) Interfere
with any relationship, contractual or otherwise, between the Parent Group and any other party, including, without limitation, any supplier,
distributor, co-venturer or joint venturer of the Parent Group, for the purpose of soliciting such other party to discontinue or reduce
its business with the Parent Group for the purpose of competing with the Business of the Parent Group.


 


With respect to
the activities described in Paragraphs (i), (ii), (iii) and (iv) above, the restrictions of this Section 12(b) shall continue during the
term of this Agreement and for a period of one (1) year thereafter.


 


13. Section
409A.


 


The provisions of this Agreement
are intended to comply with or are exempt from Section 409A of the Code (“Section 409A”) and the related Treasury Regulations
and shall be construed in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A. The Parent and
the Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions necessary,
appropriate or desirable to avoid imposition of any additional tax under Section 409A or income recognition prior to actual payment to
the Executive under this Agreement.


 


It is intended that any expense
reimbursement made under this Agreement shall be exempt from Section 409A. Notwithstanding the foregoing, if any expense reimbursement
made under this Agreement shall be determined to be “deferred compensation” subject to Section 409A (“Deferred Compensation”),
then (a) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit, (b) the amount
of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for
reimbursement, or in-kind benefits to be provided, in any other taxable year (provided that this clause (b) shall not be violated with
regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to
a limit related to the period the arrangement is in effect) and (c) such payments shall be made on or before the last day of the taxable
year following the taxable year in which the expense was incurred.


 


With respect to the time of
payments of any amount under this Agreement that is Deferred Compensation, references in the Agreement to “termination of employment”
and substantially similar phrases, including a termination of employment due to the Executive’s Disability, shall mean “Separation
from Service” from the Parent within the meaning of Section 409A (determined after applying the presumptions set forth in Treasury
Regulation Section 1.409A-1(h)(1)). Each installment payable hereunder shall constitute a separate payment for purposes of Treasury Regulation
Section 1.409A-2(b), including Treasury Regulation Section 1.409A-2(b)(2)(iii). Each payment that is made within the terms of the “short-term
deferral” rule set forth in Treasury Regulation Section 1.409A-1(b)(4) is intended to meet the “short-term deferral”
rule. Each other payment is intended to be a payment upon an involuntary termination from service and payable pursuant to Treasury Regulation
Section 1.409A-1(b)(9)(iii), et. seq., to the maximum extent permitted by that regulation, with any amount that is not exempt from Code
Section 409A being subject to Code Section 409A.

Notwithstanding anything to
the contrary in this Agreement, if the Executive is a “specified employee” within the meaning of Section 409A at the time
of the Executive’s termination, then only that portion of the severance and benefits payable to the Executive pursuant to this Agreement,
if any, and any other severance payments or separation benefits which may be considered Deferred Compensation (together, the “Deferred
Separation Benefits”), which (when considered together) do not exceed the Section 409A Limit (as defined herein) may be made
within the first six (6) months following the Executive’s termination of employment in accordance with the payment schedule applicable
to each payment or benefit. Any portion of the Deferred Separation Benefits in excess of the Section 409A Limit otherwise due to the Executive
on or within the six (6) month period following the Executive’s termination will accrue during such six (6) month period and will
become payable in one lump sum cash payment on the date six (6) months and one (1) day following the date of the Executive’s termination
of employment. All subsequent Deferred Separation Benefits, if any, will be payable in accordance with the payment schedule applicable
to each payment or benefit. Notwithstanding anything herein to the contrary, if the Executive dies following termination but prior to
the six (6) month anniversary of the Executive’s termination date, then any payments delayed in accordance with this paragraph will
be payable in a lump sum as soon as administratively practicable after the date of the Executive’s death and all other Deferred
Separation Benefits will be payable in accordance with the payment schedule applicable to each payment or benefit.


 


For purposes of this Agreement,
“Section 409A Limit” shall mean a sum equal to (x) the amounts payable within the terms of the “short-term deferral”
rule under Treasury Regulation Section 1.409A-1(b)(4) plus (y) the amount payable as “separation pay due to involuntary separation
from service” under Treasury Regulation Section 1.409A-1(b)(9)(iii) equal to the lesser of two (2) times: (i) the Executive’s
annualized compensation from the Parent based upon his annual rate of pay during the Executive’s taxable year preceding his taxable
year when his employment terminated, as determined under Treasury Regulation 1.409A-1(b)(9)(iii)(A)(1); and (ii) the maximum amount that
may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which the Executive’s
employment is terminated.
