the conscientious performance of such duties and responsibilities, except for vacation time (as set forth in Section 6(b)), absence

(iv) Tag-Along
Right.

 

(A) Without
limiting the generality of the applicable provisions of the Operating Agreement, in the event of a proposed Preferred Member Change
in Control occurring during the Employment Period (a “Tag Along Transfer”), the Company (on behalf of
the Preferred Members) shall deliver prompt written notice to Executive of any such Tag-Along Transfer (the “Tag Along
Notice”), specifying in reasonable detail the identity of the prospective transferee(s), the proposed amount and
form of consideration for the Units (as defined in the Operating Agreement) being transferred, and any other material terms and
conditions of such Tag-Along Transfer. Executive shall be entitled to sell in the Tag-Along Transfer, at the same price and on
the same terms under which the Units are proposed to be sold, all of the Common Units then held by Executive immediately prior
to such Tag-Along Transfer (the “Tag Along Right”). Executive may exercise the Tag-Along Right by delivering
to the Company (on behalf of the Preferred Members) notice of such election during the ten (10) business day period immediately
following the delivery of the Tag-Along Notice.

 

(B) The
Company (on behalf of the Preferred Members) shall use reasonable commercial efforts to obtain the agreement of the prospective
transferee(s) to the participation of the Executive in any such Tag-Along Transfer. If the Company (on behalf of the Preferred
Members) is unable to cause the prospective transferee(s) to purchase all of the shares proposed to be transferred by the Preferred
Members and Executive, then the number of shares that the Preferred Members and Executive shall be permitted to sell in such Tag-Along
Transfer shall be scaled back pro rata based on the number of shares held individually by the Preferred Members and Executive relative
to the aggregate number of shares held by both the Preferred Members and Executive in total.

 

(C) In
the event Executive elects to exercise the Tag-Along Right, such transfer shall be governed by the terms and provisions of the
contract of sale or the terms of sale between the Preferred Members and the prospective transferee(s). In the event Executive fails
to timely exercise the Tag-Along Right, or fails to timely close with respect to such right, then the Preferred Members will have
the right, in the sole discretion, to sell the Units to be sold to such prospective transferee(s), on substantially the same terms
as set forth in the contract of sale or the terms of sale with respect to such Tag-Along Transfer, free and clear of all of Executive’s
rights to participate in such Tag-Along Transfer.

in any defined contribution plan, any insurance program and any medical and other health benefit plan, in each case, sponsored

limiting the generality of the foregoing, if Executive elects to not participate in the Company’s medical and other health
benefit plans (the “Company Health Plans”), as determined by Executive in Executive’s sole discretion,
the Company shall pay for Executive’s and Executive’s family’s current medical and other health benefit plans
in Italy in lieu of participating in any of the Company Health Plans, in an amount not to exceed a cumulative maximum of $17,000

(e) Works
for Hire.

 

(i) Generally.
Executive agrees that the Company shall own all right, title and interest (including, but not limited to, patent rights, copyrights,
trade secret rights and other rights throughout the world) in any inventions, works of authorship, ideas or information made or
conceived or reduced to practice, in whole or in part, by Executive (either alone or with others) during the Employment Period
(collectively “Developments”); provided, however, that the Company shall not own
Developments for which no equipment, supplies, facility, trade secret information or Confidential Information of the Company was
used and which were developed entirely on Executive’s time, and (A) which do not relate (I) to the business of the Company
Group or (II) to the actual or demonstrably anticipated research or development of the Company Group, and (B) which do not result
from any work performed by Executive for the Company.

 

(ii) Disclosure;
Assignment. Subject to Section 8(e)(i), Executive will promptly and fully disclose to the Company, or any persons designated
by it, any and all Developments made or conceived or reduced to practice or learned by Executive, either alone or jointly with
others during the Employment Period. Executive hereby assigns all right, title and interest in and to any and all of these Developments
to the Company. Executive shall further assist the Company, at the Company’s expense, to further evidence, record and perfect
such assignments, and to perfect, obtain, maintain, enforce, and defend any rights specified to be so owned or assigned. Executive
hereby irrevocably designates and appoints the Company and its agents as attorneys-in-fact to act for and on Executive’s
behalf to execute and file any document and to do all other lawfully permitted acts to further the purposes of the foregoing with
the same legal force and effect as if executed by Executive.

 

(iii) Copyright
Act; Moral Rights. In addition, and not in contravention of Section 8(e)(i) or Section 8(e)(ii), Executive acknowledges that
all original works of authorship which are made by Executive (solely or jointly with others) within the scope of employment and
which are protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright
Act (17 USC §101). To the extent allowed by law, this Section 8(e) includes all rights of paternity, integrity, disclosure
and withdrawal and any other rights that may be known as or referred to as “moral rights” (collectively, “Moral
Rights”). To the extent Executive retains any such Moral Rights under applicable law, Executive hereby waives such
Moral Rights and consents to any action consistent with the terms of this Agreement with respect to such Moral Rights, in each
case, to the full extent of such applicable law. Executive will confirm any such waivers and consents from time to time as requested
by the Company.

 

(iv) Authorized
Disclosure. Section 1833(b) of Title 18 of the United States Code states “An individual shall not be held criminally
or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (i) is made (a) in confidence
to a Federal, State, or local government official, either directly or indirectly, or to an attorney and (b) solely for the purposes
of reporting or investigating a suspended violation of law or (ii) is made in a complaint or other document filed in a lawsuit
or other proceeding, if such filing is made under seal.” Accordingly, the Company and Executive have the right to disclose
in confidence trade secrets to Federal, State, and local government officials, or to an attorney, for the sole purpose of reporting
or investigating a suspected violation of law. The Company and Executive also have the right to disclose trade secrets in a document
filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from public disclosure. Nothing
in this Agreement is intended to conflict with Section 1833(b) of Title 18 of the United States Code or create liability for disclosures
of trade secrets that are expressly allowed by Section 1833(b) of Title 18 of the United States Code.

 

    9

     

    

 

(f) Mutual
Nondisparagement. Executive agrees that Executive shall neither, directly or indirectly, engage in any conduct or make any
statement (including through social media) disparaging or criticizing in any way the Company Group, or any of their personnel,
nor engage in any other conduct or make any other statement that could be reasonably expected to impair the goodwill of the Company
Group, the reputation of the Company Group, in each case, except to the extent required by law, and then only after consultation
with the Company to the extent possible, or to enforce the terms of this Agreement. The Company agrees that it shall not, and the
Company agrees that is shall instruct its senior executives and officers to not, directly or indirectly, engage in any conduct
or make any statement (including through social media) disparaging or criticizing in any way Executive, nor engage in any other
conduct or make any other statement that could be reasonably expected to impair the goodwill of Executive, the reputation of Executive,
in each case, (i) except to the extent required by law, and then only after consultation with Executive to the extent possible,
(ii) to enforce the terms of this Agreement, or (iii) from discussing Executive in connection with normal performance evaluations.

 

(g) Return
of Documents. In the event of the termination of Executive’s employment, Executive shall promptly deliver to the Company
(i) all property of the Company Group then in Executive’s possession; and (ii) all documents and data of any nature and in
whatever medium of the Company Group, and Executive shall not take with Executive any such property, documents or data or any reproduction
thereof, or any documents containing or pertaining to any Confidential Information.

 

(h) Confidentiality
of Agreement; Governmental Agency Exception. The parties to this Agreement agree not to disclose its terms to any Person, other
than their attorneys, accountants, financial advisors or, in Executive’s case, members of Executive’s immediate family
or, in the Company’s case, for any reasonable purpose that is reasonably related to its business operations; provided,
that this Section 8(h) shall not be construed to prohibit any disclosure required by law or in any proceeding to enforce the terms
and conditions of this Agreement. Notwithstanding anything to the contrary contained in this Agreement, this Agreement does not
limit Executive’s ability to communicate with any government agency or otherwise participate in any investigation or proceeding
that may be conducted by any government agency, including providing documents or other information, without notice to the Company
or its affiliates. This Agreement does not limit Executive’s right to receive an award for information provided to any government

    13

     

    

 

(i) Section
409A. The parties intend that any amounts payable hereunder comply with or are exempt from Section 409A of the Internal Revenue
Code of 1986, as amended (“Section 409A”) (including under Treasury Regulation §§ 1.409A-1(b)(4) (“short-term
deferrals”) and (b)(9) (“separation pay plans,” including the exceptions under subparagraph (iii) and subparagraph
(v)(D)) and other applicable provisions of Treasury Regulation §§ 1.409A-1 through A-6). For purposes of Section 409A,
each of the payments that may be made under this Agreement shall be deemed to be a separate payment for purposes of Section 409A.
This Agreement shall be administered, interpreted and construed in a manner that does not result in the imposition of additional
taxes, penalties or interest under Section 409A. The Company and Executive agree to negotiate in good faith to make amendments
to the Agreement, as the parties mutually agree are necessary or desirable to avoid the imposition of taxes, penalties or interest
under Section 409A. Neither the Company nor Executive shall have the right to accelerate or defer the delivery of any such payments
or benefits except to the extent specifically permitted or required by Section 409A. Notwithstanding the foregoing, the Company
does not guarantee any particular tax effect, and Executive shall be solely responsible and liable for the satisfaction of all
taxes, penalties and interest that may be imposed on or for the account of Executive in connection with the Agreement (including
any taxes, penalties and interest under Section 409A), and neither the Company nor any of its affiliates shall have any obligation
to indemnify or otherwise hold Executive (or any beneficiary) harmless from any or all of such taxes, penalties or interest. With
respect to the time of payments of any amounts under the Agreement that are “deferred compensation” subject to Section
409A, references in the Agreement to “termination of employment” (and substantially similar phrases) shall mean “separation
from service” within the meaning of Section 409A. For the avoidance of doubt, it is intended that any expense reimbursement
made to Executive hereunder shall be exempt from Section 409A. Notwithstanding the foregoing, if any expense reimbursement made
hereunder shall be determined to be “deferred compensation” within the meaning of Section 409A, then (a) the amount
of the indemnification payment or expense reimbursement during one taxable year shall not affect the amount of the expense reimbursement
during any other taxable year, (b) the expense reimbursement shall be made on or before the last day of Executive’s taxable
year following the year in which the expense was incurred and (c) the right to expense reimbursement hereunder shall not be subject
to liquidation or exchange for another benefit.

 

(j) Counterparts.
This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which together shall constitute
one and the same instrument. The parties hereto agree to accept a signed facsimile copy or “PDF” of this Agreement
as a fully binding original.

 

(k) Headings.
The section and other headings contained in this Agreement are for the convenience of the parties only and are not intended to
be a part hereof or to affect the meaning or interpretation hereof.

 

(l) Condition
Precedent. The effectiveness of this Agreement is contingent on (i) the Company’s successful completion of a satisfactory
background investigation and reference check, as determined by the Company in its sole discretion and in accordance with the Company’s
applicable policy and applicable law, and (ii) Executive’s compliance with applicable Federal law and the Immigration Reform
and Control Act of 1986, and as a condition of employment, Executive must complete an Employment Verification Form 1-9 and present
proof of identity and employment eligibility to work in the United States to the Company within three days following the Commencement
Date.

and Executive hereby agree as follows:

 

1. Agreement to
Employ; No Conflicts

 

Upon the terms and
subject to the conditions of this Agreement, the Company hereby agrees to continue employing Executive, and Executive hereby accepts
such continued employment by the Company. Executive represents and warrants that (a) Executive is entering into this Agreement
voluntarily, and that Executive’s employment hereunder and compliance with the terms and conditions hereof will not conflict
with or result in the breach by Executive of any agreement to which Executive is a party or by which Executive may be bound; (b)

non-solicitation or other similar covenant or agreement by which Executive is or may be bound; and (c) in connection with

have obtained in connection with Executive’s services to any prior employer.

 

2. Term; Position

(a) Term.
Unless Executive’s employment shall sooner terminate pursuant to Section 7, the Company
shall employ Executive for a term commencing on the Commencement Date and ending on the third anniversary thereof (the
“Initial Term”). Effective upon the expiration of the Initial Term and of each Additional Term (as
defined below), unless Executive’s employment shall sooner terminate pursuant to Section 7, Executive’s
employment hereunder shall be deemed to be automatically extended, upon the same terms and conditions, for an additional
period of one year (each, an “Additional Term”), in each such case, commencing upon the expiration
of the Initial Term or the then current Additional Term, as the case may be, unless, at least 60 days prior to the expiration
of the Initial Term or such Additional Term, as the case may be, either party hereto shall have notified the other party
thereto in writing that such extension shall not take effect. The period during which Executive is employed pursuant to this
Agreement shall be referred to as the “Employment Period”.

as the CEO specifies from time to time. Executive shall devote all of Executive’s skill, knowledge and business time to
the conscientious performance of such duties and responsibilities, except for vacation time (as set forth in Section 6(b)), absence
for sickness or similar disability, and time spent performing services for any charitable, religious or community organizations,
so long as such services do not materially interfere with the performance of Executive’s duties hereunder.

the year to which such Annual Bonus relates and within 30 days of the Board’s approval of audited financial statements of
the Company for the calendar year to which such Annual Bonus relates; provided, that, except as expressly
provided herein, Executive is employed by the Company on the date such Annual Bonus is to be paid. Additionally, during the Employment

is competitive with the Business or relationship of the Company Group with any Person throughout the world which is or was a customer,
client, distributor, supplier or vendor of the Business of the Company Group (x) at any time during the Employment Period
(in the case of such prohibited activity occurring during such time) or (y) during the twelve month period preceding such
prohibited activity (in the case of such prohibited activity occurring during the Restriction Period but after the date of Executive’s
termination of employment with the Company), other than any such activity on behalf of or at the request of the Company Group
during the Employment Period.

 

(e) Works
for Hire.

 

(i) Generally.
Executive agrees that the Company shall own all right, title and interest (including, but not limited to, patent rights, copyrights,
trade secret rights and other rights throughout the world) in any inventions, works of authorship, ideas or information made or
conceived or reduced to practice, in whole or in part, by Executive (either alone or with others) during the Employment Period
(collectively “Developments”); provided, however, that the Company shall not own
Developments for which no equipment, supplies, facility, trade secret information or Confidential Information of the Company was
used and which were developed entirely on Executive’s time, and (A) which do not relate (I) to the business
of the Company Group or (II) to the actual or demonstrably anticipated research or development of the Company Group, and
(B) which do not result from any work performed by Executive for the Company.

 

    7

     

    

 

(ii) Disclosure;
Assignment. Subject to Section 8(e)(i), Executive will promptly and fully disclose to the Company, or any persons
designated by it, any and all Developments made or conceived or reduced to practice or learned by Executive, either alone or
jointly with others during the Employment Period. Executive hereby assigns all right, title and interest in and to any and
all of these Developments to the Company. Executive shall further assist the Company, at the Company’s expense, to
further evidence, record and perfect such assignments, and to perfect, obtain, maintain, enforce, and defend any rights
specified to be so owned or assigned. Executive hereby irrevocably designates and appoints the Company and its agents as
attorneys-in-fact to act for and on Executive’s behalf to execute and file any document and to do all other lawfully
permitted acts to further the purposes of the foregoing with the same legal force and effect as if executed by
Executive.

 

(iii) Copyright
Act; Moral Rights. In addition, and not in contravention of Section 8(e)(i) or Section 8(e)(ii), Executive acknowledges that
all original works of authorship which are made by Executive (solely or jointly with others) within the scope of employment and
which are protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright
Act (17 USC §101). To the extent allowed by law, this Section 8(e) includes all rights of paternity, integrity, disclosure
and withdrawal and any other rights that may be known as or referred to as “moral rights” (collectively, “Moral
Rights”). To the extent Executive retains any such Moral Rights under applicable law, Executive hereby waives such
Moral Rights and consents to any action consistent with the terms of this Agreement with respect to such Moral Rights, in each
case, to the full extent of such applicable law. Executive will confirm any such waivers and consents from time to time as requested
by the Company.

 

(iv) Authorized Disclosure.
Section 1833(b) of Title 18 of the United States Code states “An individual shall not be held criminally or civilly liable
under any Federal or State trade secret law for the disclosure of a trade secret that (i) is made (a) in confidence
to a Federal, State, or local government official, either directly or indirectly, or to an attorney and (b) solely for
the purposes of reporting or investigating a suspended violation of law or (ii) is made in a complaint or other document
filed in a lawsuit or other proceeding, if such filing is made under seal.” Accordingly, the Company and Executive have
the right to disclose in confidence trade secrets to Federal, State, and local government officials, or to an attorney, for the
sole purpose of reporting or investigating a suspected violation of law. The Company and Executive also have the right to disclose
trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from
public disclosure. Nothing in this Agreement is intended to conflict with Section 1833(b) of Title 18 of the United States Code
or create liability for disclosures of trade secrets that are expressly allowed by Section 1833(b) of Title 18 of the United States
Code.

 

    8

     

    

 

(f) Mutual Nondisparagement.
Executive agrees that Executive shall neither, directly or indirectly, engage in any conduct or make any statement (including
through social media) disparaging or criticizing in any way the Company Group, or any of their personnel, nor engage in any other
conduct or make any other statement that could be reasonably expected to impair the goodwill of the Company Group, the reputation
of the Company Group, in each case, except to the extent required by law, and then only after consultation with the Company to
the extent possible, or to enforce the terms of this Agreement. The Company agrees that it shall not, and the Company
agrees that is shall instruct its senior executives and officers to not, directly or indirectly, engage in any conduct or make
any statement (including through social media) disparaging or criticizing in any way Executive, nor engage in any other conduct
or make any other statement that could be reasonably expected to impair the goodwill of Executive, the reputation of Executive,
in each case, (i) except to the extent required by law, and then only after consultation with Executive to the extent possible,
(ii) to enforce the terms of this Agreement, or (iii) from discussing Executive in connection with normal performance
evaluations.

 

(g) Return of Documents.
In the event of the termination of Executive’s employment, Executive shall promptly deliver to the Company (i) all
property of the Company Group then in Executive’s possession; and (ii) all documents and data of any nature and in
whatever medium of the Company Group, and Executive shall not take with Executive any such property, documents or data or any
reproduction thereof, or any documents containing or pertaining to any Confidential Information.

 

(h) Confidentiality
of Agreement; Governmental Agency Exception. The parties to this Agreement agree not to disclose its terms to any Person, other
than their attorneys, accountants, financial advisors or, in Executive’s case, members of Executive’s immediate family
or, in the Company’s case, for any reasonable purpose that is reasonably related to its business operations; provided,
that this Section 8(h) shall not be construed to prohibit any disclosure required by law or in any proceeding to enforce the terms
and conditions of this Agreement. Notwithstanding anything to the contrary contained in this Agreement, this Agreement does not
limit Executive’s ability to communicate with any government agency or otherwise participate in any investigation or proceeding
that may be conducted by any government agency, including providing documents or other information, without notice to the Company
or its affiliates. This Agreement does not limit Executive’s right to receive an award for information provided to any government
agencies.

 

9. Certain Acknowledgments;
Injunctive Relief with Respect to Covenants

 

(a) Executive acknowledges
and agrees that Executive will have a prominent role in the development of the goodwill of the Company Group, and has and will
establish and develop relations and contacts with the principal business relationships of the Company Group in the United States
of America and the rest of the world, all of which constitute valuable goodwill of, and could be used by Executive to compete
unfairly with, the Company Group and that (i) in the course of Executive’s employment with the Company, Executive
will obtain confidential and proprietary information and trade secrets concerning the business and operations of the Company Group
in the United States of America and the rest of the world that could be used to compete unfairly with the Company Group; (ii)
the covenants and restrictions contained in Section 8 are intended to protect the legitimate interests of the Company Group
in their respective goodwill, trade secrets and other confidential and proprietary information; and (iii) Executive desires
to be bound by such covenants and restrictions.

 

(b) Injunctive
Relief. Executive acknowledges and agrees that the covenants, obligations and agreements of Executive contained in Section
8 relate to special, unique and extraordinary matters and that a violation of any of the terms of such covenants, obligations
or agreements will cause the Company Group irreparable injury for which adequate remedies are not available at law. Therefore,
Executive agrees that the Company shall be entitled to an injunction, restraining order or such
other equitable relief (without the requirement to post bond) as a court of competent jurisdiction may deem necessary or appropriate
to restrain Executive from committing any violation of such covenants, obligations or agreements. These injunctive remedies are
cumulative and in addition to any other rights and remedies the Company Group may have.

(ii)Waiver
of Jury Trial. Each party acknowledges and agrees that any controversy which may arise under this Agreement is likely
to involve complicated and difficult issues, and therefore each party hereby irrevocably and unconditionally waives any right

waiver or discharge affecting the rights or obligations of the Company, is approved by a Person authorized thereby. No waiver by
any party hereto at any time of any breach by any other party hereto of, or compliance with, any condition or provision of this
Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the
same or at any prior or subsequent time. No waiver of any provision of this Agreement shall be implied from any course of dealing
between or among the parties hereto or from any failure by any party hereto to assert its rights hereunder on any occasion or series
of occasions.

 

(e) Legal

of independent legal counsel. In the event that any one or more of the provisions of this Agreement shall be or become invalid,
illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein
shall not be affected thereby. Executive and the Company agree that the covenants contained in Section 8 are reasonable covenants
under the circumstances, and further agree that if, in the opinion of any court of competent jurisdiction such covenants are not
reasonable in any respect, such court shall have the right, power and authority to excise or modify such provision or provisions
of these covenants as to the court shall appear not reasonable and to enforce the remainder of these covenants as so amended.

    12

     

    

 

(i) Section 409A.
The parties intend that any amounts payable hereunder comply with or are exempt from Section 409A of the Internal Revenue
Code of 1986, as amended (“Section 409A”) (including under Treasury Regulation §§ 1.409A-1(b)(4)
(“short-term deferrals”) and (b)(9) (“separation pay plans,” including the exceptions under subparagraph
(iii) and subparagraph (v)(D)) and other applicable provisions of Treasury Regulation §§ 1.409A-1 through A-6). For
purposes of Section 409A, each of the payments that may be made under this Agreement shall be deemed to be a separate payment
for purposes of Section 409A. This Agreement shall be administered, interpreted and construed in a manner that does not result
in the imposition of additional taxes, penalties or interest under Section 409A. The Company and Executive agree to negotiate
in good faith to make amendments to the Agreement, as the parties mutually agree are necessary or desirable to avoid the imposition
of taxes, penalties or interest under Section 409A. Neither the Company nor Executive shall have the right to accelerate or defer
the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A. Notwithstanding
the foregoing, the Company does not guarantee any particular tax effect, and Executive shall be solely responsible and liable
for the satisfaction of all taxes, penalties and interest that may be imposed on or for the account of Executive in connection
with the Agreement (including any taxes, penalties and interest under Section 409A), and neither the Company nor any of its affiliates
shall have any obligation to indemnify or otherwise hold Executive (or any beneficiary) harmless from any or all of such taxes,
penalties or interest. With respect to the time of payments of any amounts under the Agreement that are “deferred compensation”
subject to Section 409A, references in the Agreement to “termination of employment” (and substantially similar phrases)
shall mean “separation from service” within the meaning of Section 409A. For the avoidance of doubt, it is intended
that any expense reimbursement made to Executive hereunder shall be exempt from Section 409A. Notwithstanding the foregoing, if
any expense reimbursement made hereunder shall be determined to be “deferred compensation” within the meaning of Section
409A, then (a) the amount of the indemnification payment or expense reimbursement during one taxable year shall not affect
the amount of the expense reimbursement during any other taxable year, (b) the expense reimbursement shall be made on or
before the last day of Executive’s taxable year following the year in which the expense was incurred and (c) the
right to expense reimbursement hereunder shall not be subject to liquidation or exchange for another benefit.

 

(j) Counterparts.
This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which together shall constitute
one and the same instrument. The parties hereto agree to accept a signed facsimile copy or “PDF” of this Agreement
as a fully binding original.

 

(k) Headings.
The section and other headings contained in this Agreement are for the convenience of the parties only and are not intended to
be a part hereof or to affect the meaning or interpretation hereof.

 

(l) Condition
Precedent. The effectiveness of this Agreement is contingent on (i) the Company’s successful completion of a satisfactory
background investigation and reference check, as determined by the Company in its sole discretion and in accordance with the Company’s
applicable policy and applicable law, and (ii) Executive’s compliance with applicable Federal law and the Immigration Reform
and Control Act of 1986, and as a condition of employment, Executive must complete an Employment Verification Form I-9 and present
proof of identity and employment eligibility to work in the United States to the Company within three days following the Commencement
Date.
