and Nonuse of Confidential Information. The Employee will not disclose or use at any time during or after the Term any Confidential
Information (as defined below) of which the Employee is or becomes aware, whether or not such information is developed by the Employee,
except to the extent that such disclosure or use is directly related to and required by the Employee’s performance of duties
assigned to the Employee pursuant to this Agreement. Under all circumstances and at all times, the Employee will take all appropriate
steps to safeguard Confidential Information in the Employee’s possession and to protect it against disclosure, misuse, espionage,
loss and theft. For purposes hereof, “Confidential Information” means information that is not generally known
to the public and that was or is used, developed or obtained by the Company or its ultimate parent company, and their respective
affiliates and subsidiaries and their respective predecessors (collectively, “Company Group”) in connection
with their business. It shall not include information (a) required to be disclosed by court or administrative order, (b) lawfully
obtainable from other sources or which is in the public domain through no fault of the Employee; or (c) the disclosure of

Group generates, authors or contributes to any invention, design, new development, device, product, method of process (whether
or not patentable or reduced to practice or comprising Confidential Information), any copyrightable work (whether or not comprising
Confidential Information) or any other form of Confidential Information relating directly or indirectly to the business of the
Company Group as now or hereinafter conducted (collectively, “Intellectual Property”), the Employee acknowledges
that such Intellectual Property is the sole and exclusive property of the Company and hereby assigns all right title and interest
in and to such Intellectual Property to the Company. Any copyrightable work prepared in whole or in part by the Employee during
the Term will be deemed “a work made for hire” under Section 201(b) of the Copyright Act of 1976, as amended,
and the Company will own all of the rights comprised in the copyright therein. The Employee will promptly and fully disclose all
Intellectual Property and will cooperate with the Company to protect the Company’ interests in and rights to such Intellectual
Property (including providing reasonable assistance in securing patent protection and copyright registrations and executing all
documents as reasonably requested by the Company, whether such requests occur prior to or after termination of Employee’s
employment hereunder). As used in this Agreement, the term “Invention” means any ideas, concepts, information,

Inventions. Employee agrees that he/she will not incorporate, or permit to be incorporated, Prior Inventions (defined below)
in any Company Inventions (defined below) without the Company’s prior written consent. In addition, Employee agrees that
Employee will not incorporate into any Company software or otherwise deliver to the Company any software code licensed under the
GNU GPL or LGPL or any other license that, by its terms, requires or conditions the use or distribution of such code on the disclosure,
licensing, or distribution of any source code owned or licensed by the Company. Employee has disclosed on Exhibit A a complete
list of all Inventions that Employee has, or Employee has caused to be, alone or jointly with others, conceived, developed, or
reduced to practice prior to the commencement of Employee’s employment by the Company, in which Employee has an ownership
interest or which Employee has a license to use, and that Employee wishes to have excluded from the scope of this Agreement (collectively
referred to as “Prior Inventions”). If no Prior Inventions are listed in Exhibit A, Employee warrants that
there are no Prior Inventions. If, in the course of Employee’s employment with the Company, Employee incorporates a Prior
Invention into a Company process, machine or other work, Employee must (i) notify the Company in writing of such usage in
advance of such usage, and (ii) hereby grants the Company a non-exclusive, perpetual, fully-paid and royalty-free, irrevocable
and worldwide license, with rights to sublicense through multiple levels of sub-licensees, to reproduce, make derivative works
of, distribute, publicly perform, and publicly display in any form or medium, whether now known or later developed, make, have
made, use, sell, import, offer for sale, and exercise any and all present or future rights in, such Prior Invention


 


6.4            Assignment
of Company Inventions. Subject to the section titled “Government or Third Party” and except for Inventions that
Employee has set forth in Exhibit A, Employee hereby assigns and agrees to assign in the future (when any such Inventions
or Intellectual Property Rights are first reduced to practice or first fixed in a tangible medium, as applicable) to the Company
all Employee’s right, title, and interest in and to any and all Inventions (and all Intellectual Property Rights with respect
thereto) made, conceived, reduced to practice, or learned by Employee, either alone or with others, during the period of Employee’s
employment by the Company. Inventions assigned to the Company or to a third party as directed by the Company pursuant to the section
titled “Government or Third Party” are referred to in this Agreement as “Company Inventions.”


 


6.5            Obligation
to Keep Company Informed. During the period of Employee’s employment and for one (1) year thereafter, Employee will
promptly and fully disclose to the Company in writing (a) all Inventions authored, conceived, or reduced to practice by Employee,
either alone or with others, and (b) all patent applications filed by Employee or in which Employee is named as an inventor
or co-inventor

or Third Party. At Company’s request, Employee also agrees to assign all Employee’s right, title, and interest

Company.

of Intellectual Property Rights and Assistance. During the period of Employee’s employment and thereafter and at Company’s
cost and expense, Employee will assist the Company in every proper way to obtain and enforce United States and foreign Intellectual
Property Rights relating to Company Inventions in all countries. In the event the Company is unable to secure Employee’s
signature on any document needed in connection with such purposes, Employee hereby irrevocably designates and appoints the Company
and its duly authorized officers and agents as Employee’s agent and attorney in fact, which appointment is coupled with an
interest, to act on Employee’s behalf to execute and file any such documents and to do all other lawfully permitted acts
to further such purposes with the same legal force and effect as if executed by Employee


 






    6


     


    

 


6.8            Reporting
of Conflicts. Employee agrees to inform the Company in writing of any apparent conflicts between Employee’s work for
the Company and (a) any obligations Employee may have to preserve the confidentiality of another’s proprietary information
or materials or (b) any rights Employee may claim to any Inventions or ideas before using the same on Company’s behalf
Otherwise, the Company may conclude that no such conflict exists and Employee agrees thereafter to make no such claim against the
Company. The Company shall receive such disclosures in confidence and consistent with the objectives of avoiding any conflict of
obligations and rights or the appearance of any conflict of interest


 


6.9            Delivery
of Materials upon Termination of Employment. As requested by the Company, from time to time and upon the termination of the
Employee’s employment with the Company for any reason, the Employee will promptly deliver to the Company all copies and embodiments,
in whatever form or medium, of all Confidential Information or Intellectual Property in the Employee’s possession or within
the Employee’s control (including written records, notes, photographs, manuals, notebooks, documentation, program listings,
flow charts, magnetic media, disks, diskettes, tapes and all other materials containing any Confidential Information or Intellectual
Property) irrespective of the location or form of such material and, if requested by the Company, will provide the Company with
written confirmation that all such materials have been delivered to the Company.


 


6.10            Non-Compete.
Employee acknowledges that in the course of employment with the Company, Employee has become familiar and/or will become familiar
with any of the Company Group’s trade secrets and with other Confidential Information and that Employee’s services
have been and/or will be of special, unique and extraordinary value to the Company. Therefore, Employee hereby agrees that at any
time during his or her employment with the Company and for a period of twelve (12) months thereafter the “Non-Compete
Period”), Employee shall not directly or indirectly own, manage, control, participate in, consult with, render services
for, operate or in any manner engage (including individually or in association with any person or entity) in any business in the
world that, directly or indirectly, is competitive with the business of the Company (or with those businesses of other
entities within the Company Group to the extent that Employee has any Confidential Information related to the businesses of those
entities within the Company Group) as conducted or proposed to be conducted at any time prior to or during the Noncompete Period
(the “Restricted Business”), provided that Employee shall not be precluded from being an employee, partner,
member or owner of any business that may provide services competitive with the Restricted Business, provided that Employee does
not personally participate in any manner in the management, marketing, promotion or delivery of such services during the Non-Compete
Notwithstanding the foregoing, the Company will consider waiving this restrictive covenant, if, in the determination of the Company,
such a waiver will not be detrimental to the Company.


 


6.11            Nonsolicitation.
The Employee hereby agrees that (a) during the Term and for a period of twenty four (24) months after the termination of employment
for any reason (the “Nonsolicitation Period”), the Employee will not, directly or indirectly through another
entity, hire or actively induce or attempt to induce any employee of the Company Group to leave the employ of the Company Group,
or in any way interfere with the relationship between the Company Group any employee thereof or otherwise employ or receive the
services of any individual who was an employee or independent contractor of the Company Group during such Nonsolicitation Period
or within the twelve month period prior thereto and (b) during the Nonsoliciation Period, the Employee will not induce or

of Noncompete and Nonsolicitation. If, at the enforcement of Sections 6.10 and 6.11, a court holds that the duration, scope
or area restrictions stated herein are unreasonable under circumstances then existing, the parties agree that the maximum duration,
scope or area reasonable under such circumstances will be substituted for the stated duration, scope or area and that the court
will be permitted to revise the restrictions contained in Sections 6.10 or 6.11 to cover the maximum duration, scope and area permitted
by law.


 


6.14            Equitable
Relief. The Employee acknowledges that the covenants contained herein are reasonable and necessary to protect the legitimate
interests of the Company Group and that each and every one of the restraints is reasonable in respect to subject matter, length
of time and geographic area, and that these restraints, individually or in the aggregate, will not prevent the Employee from obtaining
other suitable employment during the period in which the Employee is bound by the restraints. The Employee acknowledges that each
of these covenants has a unique, very substantial and immeasurable value to the Company and its affiliates and that the Employee
has sufficient assets and skills to provide a livelihood while such covenants remain in force. The Employee further covenants that
the Employee will reimburse the Company and/or the Company Group (including reasonable attorneys’ fees) incurred in connection
with any action to enforce any of the provisions of this Section 6 if any of the Company Group prevails on any material issue
involved in such dispute. The Employee acknowledges that any violation of this Section 6 will result in irreparable injury
to the Company Group and agrees that the Company shall be entitled to preliminary and permanent injunctive relief, without the
necessity of proving actual damages, as well as an equitable accounting of all earnings, profits and other benefits arising from
any violation of this Section 6 by the Employee, which rights shall be cumulative and in addition to any other rights or remedies
to which the Company may be entitled. Without limiting the generality of the foregoing, the Noncompetition Period and Nonsolicitation
Period shall be extended for an additional period equal to any period during which the Employee is in breach of the Employee’s
obligations under this Section 6. The Employee represents and acknowledges that (i) the Employee has been advised by
the Company to consult the Employee’s own legal counsel in respect of this Agreement, and (ii) the Employee has had
full opportunity, prior to execution of this Agreement, to review thoroughly this Agreement with the Employee’s counsel.

of any foreign, federal, state, county or local government or any other governmental, regulatory or administrative agency or authority

8.11            Cooperation
With Regard to Litigation Waiver of Trial By Jury.


 


(a)            Employee
agrees to cooperate with the Company during the term of this Agreement and thereafter (including following Employee’s termination
of employment for any reason) by making himself or herself reasonably available to testify on behalf of the Company Group, in any
action, suit or proceeding, whether civil, criminal, administrative, or investigative, and to assist the Company Group any of its
affiliates in any such action, suit, or proceeding by providing information and meeting and consulting with its counsel and representatives.
Employee shall be fully reimbursed for any out-of-pocket expenses and time reasonably incurred by Employee in the course of such
cooperation.


 


(b)            Each
of the parties to this Agreement irrevocably and unconditionally waives the right to a trial by jury in any action, suit or proceeding
arising out of, connected with or relating to this Agreement, the matters contemplated hereby, or the actions of the parties in
the negotiation, administration, performance or enforcement of this Agreement.


 


8.12            Section 409A.


 


(a)            If
the Company determines in good faith that any provision of this Agreement would cause the Employee to incur an additional tax,
penalty, or interest under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”),
and the applicable guidance thereunder (“Section 409A”), the Company and the Employee shall use reasonable
efforts to reform such provision, if possible, in a mutually agreeable fashion to maintain to the maximum extent practicable the
original intent of the applicable provision without violating the provisions of Section 409A or causing the imposition of
such additional tax, penalty, or interest under Section 409A. The preceding provision, however, shall not be construed as
a guarantee by the Company of any particular tax effect to the Employee under this Agreement.

(b)            For
purposes of Section 409A, the right to a series of installment payments under this Agreement shall be treated as a right to
a series of separate payments.


 


(c)            With
respect to any reimbursement of expenses of, or any provision of in-kind benefits to, the Employee, as specified under this Agreement,
such reimbursement of expenses or provision of in-kind benefits shall be subject to the following conditions: (1) the expenses
eligible for reimbursement or the amount of in-kind benefits provided in one taxable year shall not affect the expenses eligible
for reimbursement or the amount of in-kind benefits provided in any other taxable year, except for any medical reimbursement arrangement
providing for the reimbursement of expenses referred to in Section 105(b) of the Code; (2) the reimbursement of
an eligible expense shall be made no later than the end of the year after the year in which such expense was incurred; and (3) the
right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit.


 


(d)            “Termination
of employment,” or words of similar import, as used in this Agreement means, for purposes of any payments under this Agreement
that are payments of deferred compensation subject to Section 409A, the Employee’s “separation from service”
as defined in Section 409A.


 


(e)            Notwithstanding
anything in this Agreement to the contrary, if the period during which the Employee has discretion to execute or revoke the general
release of claims provided for by Section 5.4 straddles two calendar years, the payments provided for by Section 5.4
shall begin as soon as practicable in the second of the two calendar years, regardless of which calendar year the Employee actually
delivers the executed release to the Company, subject to the release first becoming effective.
