NOW, THEREFORE, in consideration
of the continuation of the employment by Hudson of the Executive, the payments, rights and benefits granted, and the mutual covenants
and conditions contained herein, and for other good and valuable consideration, receipt of which is hereby acknowledged, it is
agreed:


 


1.             TERMINATION:The
following payments and benefits (hereinafter "Severance Benefits") will be provided to the Executive by Hudson in the
event of a Termination of Employment (as hereinafter defined) of the Executive:


 


A.            Executive
will continue to receive his annual base salary, based upon his annual base salary as of the date of his Termination of Employment
(as hereinafter defined), for a period of eighteen (18) months (the "Severance Period"), with payroll to be made every
two weeks, or at such other frequency based upon Hudson’s normal payroll practice. Hudson shall deduct from Executive's continuing
payroll all normal tax withholdings and deductions which Hudson is required by law to make. The initial payment shall be made within
the forty-five (45) day period following the Executive’s Termination of Employment and the Executive shall have no right
to designate the taxable year of payment.


 


B.            Executive
will also receive an amount equal to 100% of the highest bonus earned by the Executive in any calendar year within the three (3)
calendar years immediately preceeding the date of Termination of Employment (the “Bonus”), which amount shall be paid
to Executive in equal payments throughout the Severance Period made every two weeks, or at such other frequency based upon Hudson’s
normal payroll practice. Hudson shall deduct from this bonus payment all normal tax withholdings and deductions which Hudson is
required by law to make. The initial payment shall be made within the forty-five (45) day period following the Executive’s
Termination of Employment and the Executive shall have no right to designate the taxable year of payment.


 


C.            Within
the forty-five (45) day period following the Executive’s Termination of Employment, Hudson will pay to the Executive a lump
sum payment for the Executive's unused vacation for the year in which the Termination of Employment occurs, equal to the number
of prorata unused vacation days on the date of Termination of Employment, as determined in accordance with Hudson's standard vacation
policy, multiplied by the Executive's daily base salary on the date of Termination of Employment. Hudson shall deduct from this
payment all normal tax withholdings and deductions which Hudson is required by law to make. The Executive shall have no right to
designate the taxable year of payment.


 


D.            The
Executive's participation in life, health and dental insurance, disability insurance, and any other benefits (the "Benefits")
provided by Hudson to the Executive as of the date of the Termination of Employment shall be continued, or essentially equivalent
benefits provided by Hudson, for the entire Severance Period or until otherwise terminated by the Executive, on the same terms,
conditions and costs as if the Executive continued in the employ of Hudson. To the extent Benefits include health and dental insurance,
such Benefits shall be provided as COBRA continuation coverage, and not in addition to COBRA. Notwithstanding the foregoing, to
the extent Benefit coverages provided to the Executive under this Section are taxable to the Executive, Hudson’s obligation
hereunder shall not exceed the applicable dollar amount under Section 402(g)(1) (B) of the Internal Revenue Code of 1986, as amended
determined as of the year in which the Executive’s “Separation of Service” occurs which is exempt under Treasury
Reg. Section 1.409A-1(b)(9)(v)(D) (Limited Payment).

the Termination of Employment until (i) expiration of the Severance Period, (ii) termination of Severance Benefits pursuant to
paragraph "6" below, or (iii) expiration of the original term of the stock option, stock appreciation right or similar
right, whichever first occurs. No extension of an exercise period under this Agreement shall extend to a date that would cause

F.             For
purposes of this agreement, the following definitions will apply:


 


(i)          A

without Cause (as hereinafter defined) or (b) by the Executive following an event constituting Good Reason (as hereinafter defined).


 


(ii)         "Cause"
shall exist if the act(s) or conduct of the Executive make it unreasonable to require Hudson to continue to retain Executive in
its employment, such as, but not limited to, (a) the Executive's willful and continued refusal to perform, or the Executive's willful
and continued neglect of, the substantive duties of his position, (b) any willful act or omission by the Executive constituting
dishonesty, fraud or other malfeasance, (c) material nonconformance with Hudson's standard business practices and policies, including
but not limited to violation of Hudson's Code of Business Conduct and Ethics or Hudson's Substance Abuse Policy, (d) any act or
omission by the Executive which has a material adverse affect upon the financial condition or business reputation of Hudson, (e)

    	3



     


    

 


(iii)        "Good
Reason" shall mean the occurrence of any of the following: (a) at any time within a twenty-four (24) month period two individuals
are elected to Hudson’s Board of Directors whose nominations were not approved by the then sitting members of the Board of
Directors; (b) the Executive is assigned any duties or responsibilities, without his consent, that are materially inconsistent
with his position, duties, responsibilities or status, (c) Hudson requires the Executive, without his consent, to be based at a
location which is more than fifty (50) miles from Hudson's corporate headquarters, currently located at One Blue Hill Plaza, Pearl
River, New York 10965, (d) except as provided in paragraph "1.I." below, the Executive's annual base salary is reduced,
except to the extent that the annual base salaries of all Executive Officers (as defined below) are reduced due to the adverse
financial condition of Hudson and further providing that the Executive's annual base salary may not be reduced to a level that
is less than ninety (90%) percent of the Executive's annual base salary for the calendar year immediately prior to the Termination
of Employment, (e) the Executive's benefits are reduced and such reduction results in a material reduction in the Executive’s
total compensation, except to the extent that such reductions are made by Hudson on a company-wide basis and affect all Executive
Officers that participate in such benefits, (f) except as provided in paragraph "1.I." below, the Executive experiences
in any year a reduction in bonus compensation or other incentive compensation, or a reduction in the ratio of the Executive's incentive
compensation, bonus or other such payments to his base compensation, or a reduction in the method of calculation of the Executive's
incentive compensation, bonus or other such payments if these benefits or payments are calculated other than as a percentage of
base salary, except to the extent such reduction applies equally or proportionally, as the case may be, to all Executive Officers
of Hudson. Good Reason shall not be deemed to exist unless the Executive’s Termination of Employment for Good Reason occurs
within ninety (90) days following the initial existence of one of the foregoing conditions, the Executive provides Hudson with
written notice of the existence of such condition(s) within thirty (30) days after the initial existence of the condition(s), and
Hudson fails to remedy the condition within thirty (30) days after its receipt of such notice. An isolated, insubstantial and inadvertent
action not taken in bad faith and which is remedied by Hudson within ten (10) days after Hudson's receipt of notice thereof given
by the Executive shall not constitute Good Reason.

obligation to pay the compensation and to make the arrangements provided in this paragraph "1" shall be absolute and
unconditional and shall not be affected by any circumstances, including, without limitation, any offset, counterclaim, recoupment
or other right which Hudson may have against the Executive or anyone else; provided, however, that as a condition to payment of
amounts under this paragraph "1", within thirty (30) days of the Executive’s Termination of Employment, the Executive
shall have (i) executed and not revoked a general release and waiver, in form and substance reasonably satisfactory to Hudson and
the Executive, of all claims relating to the Executive's employment by Hudson and the termination of such employment, including,
without limitation, discrimination claims (including without limitation age discrimination), employment-related tort claims, contract
claims and claims under this Agreement (other than claims with respect to benefits under any tax-qualified retirement plans or
continuation of coverage or benefits solely as required under ERISA), and (ii) executed an agreement expressly acknowledging and

H.            All
amounts payable by Hudson pursuant to this paragraph "1" shall be paid without notice or demand. The Executive shall
not be obligated to seek other employment in mitigation of the amounts payable or arrangements made pursuant to this paragraph
"1" and, except as provided in paragraph "6" below, the obtaining of any other employment shall not result
in a reduction of Hudson's obligation to make the payments, benefits and arrangements required to be made under this paragraph
"1".


 


I.              Executive
expressly acknowledges that the following shall not constitute "Good Reason" for purposes of this paragraph "1":


 


(i)          Establishing
a new or different bonus or incentive compensation plan(s) in any subsequent year based upon new or different criteria for calculating
the applicability of, and the amount of any bonus or incentive compensation award due to the Executive, provided that any new or
different bonus or incentive compensation plan, and any award under said plan, applies equally or proportionally, as the case may
be, to all Executive Officers; except that Hudson may establish separate performance criteria and payment amounts for awards under
such plan for each Named Executive that are reasonably achievable and reasonably related to such Executive's normal duties and
responsibilities;


 


(ii)         A
reduction of the Executive's bonus compensation or other incentive compensation that (a) results from Hudson operating at a level
of performance below Hudson's Budget, (b) results from the Executive's failure or inability to attain, in whole or in part, any
or all of the performance criteria established for the Executive under the said plan, (c) results from application of the terms
of such bonus or incentive compensation plan, or (d) is based upon the Executive's performance, or non-performance, of his normal
duties and responsibilities during the period covered by the bonus or incentive compensation plan including, without limition,
due to the Executive's Disability (as defined herein);


 


(iii)        A

2.             TERMINATION
FOR CAUSE:Hudson may at any time terminate the employment of the Executive for Cause (as defined in paragraph "1"
above) upon five (5) days prior written notice to Executive. If Executive is terminated for cause, he shall be entitled to no Severance
Benefits and shall be entitled to no bonus payment that might otherwise be owed to him even if he worked for the entire year. In
the event of termination under this section, Hudson shall pay Executive all amounts which are then accrued but unpaid, including
unpaid vacation as determined in accordance with Hudson's standard vacation policy, within thirty (30) days after the date of notice.
Hudson shall have no further or additional liability to Executive.


 


3.             SICK
LEAVE


 


A.            If
with or without reasonable accomodation Executive is physically or mentally unable to perform his duties, or is otherwise absent
for medical reasons, Hudson shall continue to pay base salary and provide benefits to the Executive (“Sick Leave”).
However, if a continuous period of Sick Leave exceeds eight (8) consecutive weeks, Hudson’s obligation
with regard to base salary upon the expiration of the eight (8) consecutive weeks shall be limited to paying 75% of base salary.
If the Executive returns to full service, his full base salary shall be reinstated to the pre-adjustment amount. As a condition
to the receipt of the foregoing base salary and benefits, the Executive agrees that he shall provide Hudson such information as
Hudson may reasonably request from time to time to permit Hudson to make a determination that the Executive is entitled to sick
pay under this provision. Hudson shall reduce the amount paid to the Executive during such Sick Leave by an amount equal
to any disability payments or benefits actually received by Executive under or pursuant to any disability program or supplemental
disability insurance plan(s) provided by Hudson at Hudson's expense unless such reduction results
in a violation of Code Section 409A.


 


B.            Notwithstanding
the foregoing, Hudson may terminate the employment of Executive at any time after Executive’s continuous period of Sick Leave
exceeds 120 calendar days. Termination of the Executive after the said 120 calendar period shall not be deemed a Termination for
Cause (as defined in paragraph "1" above") and shall entitle the Executive to receive the payments and benefits
provided by Paragraph "1" upon Termination of Employment based upon Executive’s
full base salary, and for purposes of such payments and benefits, the Severance Period shall be deemed to commence
as of the date of the Termination of Employment resulting under this paragraph “3.B.”. 


 


C.            Notwithstanding
anything to the contrary contained herein, in the event that during the period the Executive is on Sick Leave, and prior to any
Termination of Employment pursuant to paragraph “3.B.”, there is deemed a “Separation from Service” (as
that term is defined in Section 409A of the Internal Revenue Code for purposes of a permissible event), Hudson and the Executive
agree that such Separation of Service shall be treated as a Termination of Employment. Such Termination shall not be deemed a Termination
for Cause (as defined in paragraph “1” above”) and shall entitle the Executive to receive the payments and benefits
provided by Paragraph "1" upon Termination of Employment based upon Executive’s
full base salary, provided that, for purposes of such payments and benefits, the Severance Period shall commence as of the date
of the Separation from Service as described in this paragraph “3.C”, and shall be based upon Executive’s full
base salary. 


 






    	6



     


    

 


D.            Notwithstanding
anything to the contrary contained herein, in the event that during the period the Executive is on Sick Leave, and prior to any
Termination of Employment pursuant to paragraph “3.B.” or any Separation from Service pursuant to paragraph “3.C.”,
the Executive becomes “Disabled,” (as defined in Code Section 409A for purposes of a permissible payment event) Hudson
and the Executive agree that the Executive’s Disability shall entitle the Executive to receive the payments and benefits
provided by Paragraph "1" upon Termination of Employment based upon Executive’s
full base salary and Bonus. For purposes of such payments and benefits, the Severance Period shall commence as of the date of the
Disability as described in this paragraph “3.D”. 


 


4.             CONFIDENTIALITY:


 


A.            Employee
expressly acknowledges and agrees as follows:


 


(i)          Hudson
expends a significant amount of funds annually on researching and developing solutions and proprietary techniques related to the
products and services it offers or is seeking to offer, and has developed substantial confidential, proprietary, and trade secret
information, and this confidential, proprietary, and trade secret information, if misused, disclosed, misappropriated or used by
others, would result in irreparable harm to Hudson.


 


(ii)         Hudson’s
Confidential Information (as hereinafter defined) constitutes valuable commercial assets of Hudson and is not readily available
to the general public or by any persons not employed by or otherwise not associated in a position of trust with Hudson. Hudson
keeps its Confidential Information confidential (other than to the extent filings are required for patents) by, among other things,
restricting access to only those who need the information to perform their Hudson job function and prohibiting the use or disclosure
of Confidential Information to anyone not authorized to receive or use the Confidential Information.


 


(iii)        Employee’s
position with Hudson will continue to provide Employee with access to or knowledge of Hudson’s Confidential Information.


 


(iv)        Hudson’s
Confidential Information will become known to Employee only as a result of his/her employment with Hudson. To the extent that Employee
was previously engaged, on his own or with others, in a business that provided the same or similar services as those provided by
Hudson, Employee further acknowledges that such prior business knowledge and experience, and any familiarity with entities that
are actual or potential customers for the business, shall not permit or allow Employee to contend that Hudson’s Confidential
Information is not confidential or should not be protected from use or misappropriation.


 






    	7



     


    

 


B.            In
light of the foregoing, Employee acknowledges and agrees as follows:

all or any part of the Confidential Information, other than for the purposes authorized by Hudson, or only for the benefit of Hudson.


 


(ii)         Hudson
shall be the sole owner of, and Employee hereby assigns to Hudson, any and all property rights to all Intellectual Property (as
hereinafter defined) made, conceived, originated, devised, discovered, invented, or developed before, during or after the term
of Employee’s employment with Hudson, whether or not Employee was involved either alone or with others, if it was in whole
or in part developed during the course of Employee’s employment or by Employee’s use of any property of Hudson. This
ownership provision does not apply to creations of the Employee which are made in the Employee’s own time, without the use
of any Hudson resources, and which do not relate in any way to Hudson’s business. Employee agrees to cooperate fully and
assist Hudson or its designee in the performance of any lawful acts that Hudson at its discretion deems necessary, and to execute
and deliver without charge any documents reasonably required by Hudson, to secure any patent, copyright, trademark, and other protection
for Intellectual Property and improvements thereon, and to assign to and vest in Hudson the entire interest therein in the United
States and all foreign countries.


 


(iii)        Upon
request by Hudson at any time, or upon termination from employment with Hudson, whichever is sooner, Employee shall immediately
deliver to Hudson any and all information and property of Hudson in whatever form it exists, including but not limited to all Confidential
Information and all copies thereof or materials containing or derived from Confidential Information.


 


C.            As
used in this Agreement, “Confidential Information” means all information not publicly available (but including information
that is publicly available as a result of a breach by Employee of paragraphs “4” and “5”) and not generally
known or used by Hudson’s competitors, or in the industry, and which could be harmful to Hudson if disclosed to persons outside
of Hudson and which includes, but is not limited to:

utilized by Hudson; and the success or lack of success of those programs and strategies.


 


“Confidential Information” does
not include general skills, experience or information that is generally available to the public, other than information which has
become generally available as a result of Employee’s direct or indirect act or omission. “Confidential Information”
also does not include information regarding Employee’s own pay and benefits, information as to the terms and conditions of
employment, or information that is deemed not confidential under Section 7 of the National Labor Relations Act. Nothing in this
Agreement should be construed as restricting the Employee’s right to engage in legally protected activities under applicable
law, including participating in investigations conducted by any governmental agency or entity or making other disclosures that
are protected under the whistleblower provisions of applicable law or regulation.


 


D.            As

construction, marketing, and sales of the products and services provided by Hudson and which includes, but is not limited to: any
and all patents, patents pending; trademarks, copyrights, and any and all applications for same issued to and/or applied for by

material defining, describing, illustrating, or documenting in any fashion, all such property, whether written or not and whether

A.            Employee
expressly acknowledges and agrees as follows:

light of the foregoing, Employee agrees, that while Employee is employed by Hudson, and continuing until the expiration of the
Covenant Period (as hereinafter defined):


 


(i)            Employee

whether for profit or not-for-profit, by being employed by, participating in, or otherwise being materially connected in the conduct
of any business activity that involves providing products or services that are like or similar to, or competitive with, or would
replace or be a substitute for, any one or more of the products and services provided by Hudson (hereinafter “Competitive

Employee from unfairly benefiting by violations of this paragraph “5”, the provisions and requirements of this paragraph
“5” shall be extended for a period of time beyond the Covenant Period equal in length to the total length of time during
which Employee is in violation of any one or more provisions of this Section.


 


G.            In
the event it is determined by a Court of competent jurisdiction that any provision or portion of a provision of this paragraph
“5” is not enforceable under the law governing this Agreement, the unenforceable provision or portion thereof may be
stricken, and the remainder of the provision and of this paragraph “5” shall be valid and fully enforceable, in all
respects, as if the provision or portion of a provision deemed unenforceable had never been a part of the Agreement. Further, if
any provision of this Agreement is found to be overbroad or unenforceable, the court or any other authority with competent jurisdiction
is expressly authorized to conform the provision to the extent necessary to remedy any deficiency and render it valid and enforceable.


 


6.             REMEDIES:


 


A.            In
the event that Executive breaches any term or provision of paragraphs "4" or "5" of this Agreement, Hudson
shall be immediately, permanently and irreparably damaged and shall be entitled, in addition to, and without limiting Hudson's
right to, any and all other legal and equitable remedies and damages, (i) to a temporary restraining order ex parte, to a preliminary
injunction, and to a permanent injunction, to restrain Executive’s actions or the actions of others acting on Executive’s
behalf, (ii) to terminate all future Severance Benefits through the remainder of the Severance Period, and (iii) to recover from
the Executive all Severance Benefits actually paid to the Executive, including any costs or expenses actually incurred by Hudson
in providing such Severance Benefits. Executive agrees that Executive will not be damaged by enforcement of this covenant as Executive
can obtain many other types of gainful employment without violating the provisions of paragraphs "4" or "5",
so that no bond shall be required, and if the Court requires a bond to be posted, it shall not exceed $500.00.


 


B.            All of Executive's covenants
and obligations under paragraphs "4" and "5" of this Agreement shall survive, and shall remain enforceable,
for so long as Executive is employed and after termination of employment for any reason, and shall survive despite future promotions,
raises, changes in position or compensation, demotions, and the execution of new agreements with Hudson, and shall inure to the
benefit of Hudson’s successors and assigns, unless Hudson executes in writing an agreement expressly terminating the covenants
of paragraphs "4" and "5".


 


C.            Hudson and Executive
shall each bear and be responsible for their own attorneys' fees, expenses and disbursements incurred in any litigation brought
by either party to enforce or interpret any provision contained in paragraphs "4" or "5" of this Agreement.


 


7.             NOTICES:All
notices required or permitted to be given under this agreement shall be sufficient if in writing and if sent by certified mail,
return receipt requested, to the Executive at his residence, and to Hudson at its principal office located at PO Box 1541, One

by giving proper notice.

surviving corporation in a merger with Hudson.


 


9.             EMPLOYMENT
AT WILL; CONSEQUENCES OF TERMINATION: Nothing herein shall be deemed to create an agreement for employment of Executive for
any specified term or period of time. Hudson expressly agrees that at any time the Executive may resign or otherwise terminate
his or her employment with Hudson, for any reason or for no reason, subject to the provisions contained herein. Likewise, the Executive
expressly agrees that at any time Hudson may terminate the employment of the Executive for any reason or for no reason, subject

the Executive for the Executive's reasonable attorneys' fees, expenses and disbursements incurred in such litigation, including
the costs of enforcement.


 


11.           CONTROLLING
LAW:This Agreement and all other issues regarding the employment of the Employee shall be governed by the laws of the State
of New York, without reference to its conflicts of law principles.


 


12.           ENTIRE
AGREEMENT: This Agreement represents the entire agreement and understanding of the parties regarding the employment of the
Executive, and all prior or contemporaneous agreements, representations, or understanding are expressly superseded by, and do not
survive this Agreement. Executive has not relied upon any inducement, promise, representation, or assurance, other than those expressly
set out herein. Except as expressly permitted herein, this Agreement may not be modified or amended except in writing signed by
all parties hereto.

13.           COMPLIANCE
WITH CODE SECTION 409A:


 


A.            It
is the intention of Hudson and the Executive that the payments, benefits and rights to which the Executive could be entitled pursuant
to this Agreement comply with Code Section 409A of the Internal Revenue Code of 1986, as amended (“Code”), the Treasury
regulations and other guidance promulgated or issued thereunder (“Section 409A”), to the extent that the requirements
of Section 409A are applicable thereto, and after application of all available exemptions, including but not limited to, the “short-term
deferral rule” and “involuntary separation pay plan exception” and the provisions of this Agreement shall be
construed in a manner consistent with that intention. If any provision of this Agreement (or of any award of compensation, including
equity compensation or benefits) would cause the Executive to incur any additional tax or interest under Code Section 409A, Hudson
shall, upon the specific request of the Executive, use its reasonable business efforts to in good faith reform such provision to
comply with Code Section 409A; provided, that to the maximum extent practicable, the original intent and economic benefit to the
Executive and Hudson of the applicable provision shall be maintained, but Hudson shall have no obligation to make any changes that
could create any additional economic cost or loss of benefit to Hudson. Hudson shall not have any liability to the Executive with
respect to tax obligations that result from the application of Code Section 409A and makes no representation with respect to the
tax treatment of the payments and/or benefits provided under this Agreement. Any provision required for compliance with Section
409A that is omitted from this Agreement shall be incorporated herein by reference and shall apply retroactively, if necessary,
and be deemed a part of this Agreement to the same extent as though expressly set forth herein.


 


B.            With
regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by
Code Section 409A, (i) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit,
(ii) the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect
the expense eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year, provided that the foregoing
clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Code Section 105(b) solely
because such expenses are subject to a limit related to the period the arrangement is in effect and (iii) such payments shall be
made on or before the last day of the Executive’s taxable year following the taxable year in which the expense was incurred.


 


C.            For
purposes of applying the provisions of Section 409A to this Agreement, each separately identified amount to which the Executive
is entitled under this Agreement shall be treated as a separate payment within the meaning of Section 409A. In addition, to the
extent permissible under Section 409A, any series of installment payments under this Agreement shall be treated as a right to a
series of separate payments.


 


D.            Neither
Hudson nor the Executive, individually or in combination, may accelerate any payment or benefit that is subject to Section 409A,
except in compliance with Section 409A and the provisions of this Agreement, and no amount that is subject to Section 409A shall
be paid prior to the earliest date on which it may be paid without violating Section 409A.


 






    	14



     


    

 


E.            If
and to the extent required to comply with Section 409A, a Termination of Employment, as defined above, shall not be deemed to have
occurred for purposes of this Agreement providing for the payment of any amounts or benefits upon or following a Termination of
Employment unless such termination is also a “Separation from Service” within the meaning of Section 409A (excluding
death) and, for purposes of any provision of this Agreement, references to Termination of Employment, “termination,”
“termination of employment” or like terms shall mean “Separation from Service” (excluding death).


 


F.            If
the Executive is deemed on the date of termination of his employment to be a “specified employee,” within the meaning
of that term under Code Section 409A(a)(2)(B) and using the identification methodology selected by Hudson from time to time, or
if none, the default methodology, then with regard to any payment or the providing of any benefit subject to this Section, to the
extent required to be delayed in compliance with Code Section 409A(a)(2)(B), and any other payment or the provision of any other
benefit that is required to be delayed in compliance with Code Section 409A(a)(2)(B), such payment or benefit shall not be made
or provided prior to the earlier of (i) the expiration of the six-month period measured from the date of the Executive’s
Separation from Service or (ii) the date of the Executive’s death. In this regard, it is the intention and understanding
of Hudson and the Executive that payments made following a Termination of Employment under Paragraph “1” shall be exempt
under the “short-term deferral rule” and “involuntary separation pay plan exception”, and other applicable
exceptions, from the requirements of Code Section 409A(a)(2)(B), and are not required and shall not be delayed. Absent such exception,
on the first day of the seventh month following the date of Executive’s Separation from Service or, if earlier, on the date
of his death, all payments delayed pursuant to this Section (whether they would have otherwise been payable in a single sum or
in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum, and any remaining payments
and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them
herein. The determination of whether the Executive is a “specified employee” shall be made by Hudson in good faith
applying Section 409A.


 


IN WITNESS THEREOF, the parties have executed
this agreement as of the date written above.
