be available to the Company at all times.

 

		7.5	Execution of Documents. Whenever requested by the Company, both during the period
of the Executive’s employment and thereafter, the Executive will promptly sign and deliver to the Company any and all applications,
assignments and other documents that the Company considers necessary or desirable in order to: (a) assign, apply for, obtain, and
maintain any Intellectual Property Rights in the United States and for other countries relating to any Work Product, (b) assign
and convey to the Company or its designee the sole and exclusive right, title, and interest in and to all Intellectual Property,
(c) provide evidence regarding the Intellectual Property that the Company considers necessary or desirable, and (d) confirm the
Company’s ownership of the Intellectual Property, all without royalty or any other further consideration to the Executive.

of the Executive’s employment and thereafter, the Executive will assist the Company in assigning, obtaining, maintaining,
defending, registering and from time to time enforcing, in any and all countries, the Company’s right to the Intellectual
Property. This assistance may include, without limitation, testifying in a suit or other proceeding. If the Company requires assistance
from the Executive after termination of his employment, the Executive will be compensated for time actually spent in providing
assistance at an hourly rate equivalent to his compensation at the time his employment was terminated together with his reasonable,
actual out-of-pocket expenses incurred in providing such assistance.

 

		7.7	Power of Attorney. For use in the case that the Company cannot obtain the Executive’s
signature on any document that the Company considers necessary or desirable in order to assign, apply for, prosecute, obtain, or
enforce any Intellectual Property, whether due to the Executive’s non-cooperation, unavailability, or any other reason, the
Executive hereby irrevocably designates and appoints the Company and each of its duly authorized officers and agents as his agent
and attorney-in-fact to act for, and on the Executive’s behalf, to execute and file any such document and to do all other
lawfully permitted acts to further the assignment, transfer to the Company, application, registration, prosecution, issuance, and
enforcement of all Intellectual Property, with the same force and effect as if executed and delivered by the Executive.

		7.8	Prior Inventions. The Executive represents that any inventions, original works of
authorship, discoveries, concepts or ideas, if any, to which the Executive presently has any right, title or interest, and which
were previously conceived either wholly or in part by the Executive, and that the Executive desires to exclude from the operation
of this Agreement are identified on Schedule A of this Agreement (each a “Prior Invention”). The
Executive represents that the list contained in Schedule A is complete to the best of his knowledge. If during the Executive’s
retention with the Company, the Executive incorporates a Prior Invention into a Company product, process or service or its use,
the Executive shall be deemed to have automatically granted to the Company a nonexclusive, royalty-free, irrevocable, perpetual,
worldwide license to make, have made, modify, display, perform sell and otherwise use such Prior Invention as part of or in connection
with any Company product, process or service. The Executive shall not incorporate a Prior Invention into a Company product, process
or service or its use without the Company’s prior written consent.

                                         foregoing covenant shall cover the Executive’s activities in every part of the
                                         world. The foregoing shall not apply to the Executive’s ownership of shares in

adequate remedy in the event that the Executive breaches Section 6, 7, 8 or 12 of this Agreement and that the Company will suffer
irreparable damage and injury in such event. The Executive agrees that the Company, in addition to any other available rights and
remedies, shall be entitled to seek an injunction (without the necessity of posting a bond) restraining the Executive from committing
or continuing any violation of Section 6, 7, 8 or 12 of this Agreement.

 

		10.	TERM; TERMINATION.

 

		10.1	Term. Unless earlier terminated in accordance with the provisions of this Section
10, the term of this Agreement shall commence on the Effective Date and shall continue thereafter for a period of two (2) years
(the “Initial Term”). If the Company continues to employ the Executive after the expiration of the Initial

the reasonable satisfaction of the Board after written notice thereof and a reasonable opportunity to respond and/or cure of not

that the Executive reported to at the commencement of his employment with the Company; (ii) a reduction in the Executive’s

employment with the Company is terminated by the Company without Cause or by the Executive for Good Reason during the Initial Term,
(A) the Company shall (i) pay to the Executive an amount equal to twelve months of his then current Base Salary under Section 4.1
above (less applicable withholdings and authorized deductions), to be paid in equal installments bimonthly in accordance with the
Company’s customary payroll practices, commencing sixty (60) days following the date of termination of employment and (ii)
if the Executive then participates in the Company’s medical and/or dental plans and the Executive timely elects to continue
and maintain group health plan coverage pursuant to COBRA, reimburse the Executive for the cost of health insurance under COBRA
for a period of twelve months; provided, however, that if and to the extent that the Company may not provide such
COBRA reimbursement without incurring tax penalties or violating any requirement of the law, the Company shall use its commercially
reasonable best efforts to provide substantially similar assistance in an alternative manner, provided that the cost of doing so
does not exceed the cost that the Company would have incurred had the COBRA reimbursement been provided in the manner described
above or cause a violation of Section 409A (as defined below), and (B) if the Executive is entitled to a Bonus, subject to the
Board’s discretion and approval as set forth in Section 4.2 above, the Company shall pay such Bonus in accordance with the
terms of the applicable plan and on the same basis as other participants in the plan except that the Bonus amount shall be prorated

Notwithstanding anything to the contrary contained herein, to the extent the Company immediately terminates the Executive’s
employment in lieu of the 30 day notice period referenced in Section 10.5 above, such 30 day notice period shall be deemed to be
included in the period of payments and benefits provided for in this Section 11.2 (and no additional compensation shall be provided

seven (7) calendar days following the date of termination of employment. The Severance Payments are subject to the Executive’s
execution and delivery of such Release Agreement within 45 days of the Executive’s receipt of the Release Agreement and the
Executive’s non-revocation of such Release Agreement.

 

		11.4	Post-Termination Breach. Notwithstanding anything to the contrary contained in this
Agreement, the Company’s obligation to provide the Severance Payments will immediately cease if the Executive breaches any
of the provisions of Sections 6, 7 or 8, the Release Agreement or any other Agreement the Executive has with the Company.

 

    	Page 9

    	 

    

  

		11.5	No Other Payments or Benefits. The Executive acknowledges and agrees that upon the
termination of his employment, no other benefits, compensation or remuneration of any kind is owed by the Company to the Executive

		11.6	Survival. Notwithstanding anything to the contrary set forth herein, Sections 6,
7, 8, 9 and 11-19 of this Agreement and any remedies for the breach thereof, shall survive the termination of this Agreement under
the terms hereof. Termination of this Agreement shall not relieve or release either party from any rights, liabilities or obligations
which it/he has accrued prior the effective date of such termination.

 

		12.	RETURN OF COMPANY PROPERTY; EXIT INTERVIEW. Upon termination of the Executive’s
employment with the Company for any reason, the Executive will promptly:

 

		(a)	Deliver to the Company all documents and other tangible media in the Executive's possession or
control that evidence, contain or reflect (A) Confidential Information or (B) Work Product, in each case whether prepared by the
Executive or otherwise coming into the Executive’s possession or control;

 

		(b)	Destroy any intangible materials that evidence, contain or reflect Confidential Information or
Work Product on equipment or media not owned by the Company; and

 

		(c)	Return to the Company all equipment, files, software programs and other personal property belonging
to the Company.

 

Upon termination of the Executive’s
employment with the Company for any reason, the Executive will attend an exit interview with a representative of the Company to
review the Executive’s continuing obligations under this Agreement.

 

		13.	ENTIRE AGREEMENT. This Agreement constitutes the entire agreement between the parties
with respect to the subject matter hereof and supersedes all contemporaneous and prior agreements and understandings between them
as to such subject matter. Not in limitation of the foregoing, this Agreement supersedes the Employment Agreement between the Executive
and JBT dated January 6, 2014, which has been terminated. Except as otherwise expressly provided herein, this Agreement may not
be amended except by an instrument in writing executed by the Company and the Executive.

 

		14.	ASSIGNMENT. The Executive shall not be permitted to assign this Agreement or any
rights or obligations hereunder without the prior written consent of the Company.

 

    	Page 10

    	 

    

  

		15.	GOVERNING LAW; JURISDICTION. This Agreement shall be construed and enforced in accordance
with and governed by the laws of the Commonwealth of Massachusetts without giving effect to the principles of conflicts of laws
thereof. The parties hereby consent and submit to the exclusive jurisdiction and venue of the courts located in Boston, Massachusetts
in connection with any actions or proceedings brought against either of them (or each of them) arising out of or relating to this
Agreement.

 

		16.	MISCELLANEOUS. No waiver by either party of any term or condition of this Agreement,
whether by conduct or otherwise, in any one or more instance, shall be deemed a continuing waiver of any such term or condition,
or a waiver of any other term or condition of this Agreement. Headings set forth in this Agreement are solely for the convenience
of the parties and have no legal effect. If any provision of this Agreement shall be found to be invalid by any court having competent
jurisdiction, the invalidity of such provision shall not affect the validity of the remaining provisions hereof. This Agreement
shall be (i) binding upon, and will inure to the benefit of, the parties and their permitted respective successors and assigns,
(ii) construed without presumption of any rule requiring construction to be made against the party causing it to be drafted and
(iii) executed in any number of counterparts, each of which will for all purposes be deemed to be an original, and all of which
are identical.

 

		17.	TAX WITHHOLDING. The Company or other payor is authorized to withhold from any benefit
provided or payment due hereunder, the amount of withholding taxes due any federal, state or local authority in respect of such
benefit or payment and to take such other action as may be necessary in the opinion of the Board to satisfy all obligations for
the payment of such withholding taxes. The Executive will be solely responsible for all taxes assessed against him with respect
to the compensation and benefits described in this Agreement, other than typical employer-paid taxes such as FICA, and the Company
makes no representations as to the tax treatment of such compensation and benefits.

 

    	Page 11

    	 

    

  

		18.	SECTION 409A COMPLIANCE. All payments under this Agreement are intended to comply
with or be exempt from the requirements of Section 409A of the Code and regulations promulgated thereunder (“Section 409A”).
As used in this Agreement, the “Code” means the Internal Revenue Code of 1986, as amended. To the extent permitted
under applicable regulations and/or other guidance of general applicability issued pursuant to Section 409A, the Company reserves
the right to modify this Agreement to conform with any or all relevant provisions regarding compensation and/or benefits so that
such compensation and benefits are exempt from the provisions of 409A and/or otherwise comply with such provisions so as to avoid
the tax consequences set forth in Section 409A and to assure that no payment or benefit shall be subject to an “additional
tax” under Section 409A. To the extent that any provision in this Agreement is ambiguous as to its compliance with Section
409A, or to the extent any provision in this Agreement must be modified to comply with Section 409A, such provision shall be read
in such a manner so that no payment due to the Executive shall be subject to an “additional tax” within the meaning
of Section 409A(a)(1)(B) of the Code. If necessary to comply with the restriction in Section 409A(a)(2)(B) of the Code concerning
payments to “specified employees,” any payment on account of the Executive’s separation from service that would
otherwise be due hereunder within six (6) months after such separation shall be delayed until the first business day of the seventh
month following the date of termination of employment and the first such payment shall include the cumulative amount of any payments
(without interest) that would have been paid prior to such date if not for such restriction. Each payment in a series of payments
hereunder shall be deemed to be a separate payment for purposes of Section 409A. In no event may the Executive, directly or indirectly,
designate the calendar year of payment. All reimbursements provided under this Agreement shall be made or provided in accordance
with the requirements of Section 409A, including, where applicable, the requirement that (i) any reimbursement is for expenses
incurred during the Executive’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount
of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other
calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following
the year in which the expense is incurred, and (iv) the right to reimbursement is not subject to liquidation or exchange for another
benefit. Notwithstanding anything contained herein to the contrary, the Executive shall not be considered to have terminated employment
with the Company for purposes of Section 11.2 unless the Executive would be considered to have incurred a “termination of
employment” from the Company within the meaning of Treasury Regulation §1.409A-1(h)(1)(ii). In no event whatsoever shall
the Company be liable for any additional tax, interest or penalty that may be imposed on the Executive by Section 409A or damages
for failing to comply with Section 409A.

 

		19.	280G MODIFIED CUTBACK.

 

		(a)	If any payment, benefit or distribution of any type to or for the benefit of the Executive, whether
paid or payable, provided or to be provided, or distributed or distributable pursuant to the terms of this Agreement or otherwise
(collectively, the “Parachute Payments”) would subject the Executive to the excise tax imposed under Section
4999 of the Code (the “Excise Tax”), the Parachute Payments shall be reduced so that the maximum amount of the
Parachute Payments (after reduction) shall be one dollar ($1.00) less than the amount which would cause the Parachute Payments
to be subject to the Excise Tax; provided that the Parachute Payments shall only be reduced to the extent the after-tax value of
amounts received by the Executive after application of the above reduction would exceed the after-tax value of the amounts received
without application of such reduction. For this purpose, the after-tax value of an amount shall be determined taking into account
all federal, state, and local income, employment and excise taxes applicable to such amount. Unless the Executive shall have given
prior written notice to the Company to effectuate a reduction in the Parachute Payments if such a reduction is required, which
notice shall be consistent with the requirements of Section 409A to avoid the imputation of any tax, penalty or interest thereunder,
then the Company shall reduce or eliminate the Parachute Payments by first reducing or eliminating accelerated vesting of stock
options or similar awards, then reducing or eliminating any cash payments (with the payments to be made furthest in the future
being reduced first), then by reducing or eliminating any other remaining Parachute Payments; provided, that no such reduction
or elimination shall apply to any non-qualified deferred compensation amounts (within the meaning of Section 409A) to the extent
such reduction or elimination would accelerate or defer the timing of such payment in manner that does not comply with Section
409A.

 

    	Page 12

    	 

    

  

		(b)	An initial determination as to whether (x) any of the Parachute Payments received by the Executive
in connection with the occurrence of a change in the ownership or control of the Company or in the ownership of a substantial portion
of the assets of the Company shall be subject to the Excise Tax, and (y) the amount of any reduction, if any, that may be required
pursuant to the previous paragraph, shall be made by an independent accounting firm selected by the Company (the “Accounting
Firm”) prior to the consummation of such change in the ownership or effective control of the Company or in the ownership
of a substantial portion of the assets of the Company. The Executive shall be furnished with notice of all determinations made
as to the Excise Tax payable with respect to the Executive’s Parachute Payments, together with the related calculations of
the Accounting Firm, promptly after such determinations and calculations have been received by the Company.

 

		(c)	For purposes of this Section 19, (i) no portion of the Parachute Payments the receipt or enjoyment
of which the Executive shall have effectively waived in writing prior to the date of payment of the Parachute Payments shall be
taken into account; (ii) no portion of the Parachute Payments shall be taken into account which in the opinion of the Accounting
Firm does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code; (iii) the Parachute
Payments shall be reduced only to the extent necessary so that the Parachute Payments (other than those referred to in the immediately
preceding clause (i) or (ii)) in their entirety constitute reasonable compensation for services actually rendered within the meaning
of Section 280G(b)(4) of the Code or are otherwise not subject to disallowance as deductions, in the opinion of the auditor or
tax counsel referred to in such clause (ii); and (iv) the value of any non-cash benefit or any deferred payment or benefit included
in the Parachute Payments shall be determined by the Company’s independent auditors based on Sections 280G and 4999 of the
Code and the regulations for applying those sections of the Code, or on substantial authority within the meaning of Section 6662
of the Code.
