The Restricted Party acknowledges and agrees that the Restricted Party: (a) has acquired certain Confidential Information
(as defined below); (b) has been actively involved in the management of the business of the Company and in the development of
the goodwill, and vendor and customer relationships of such business and has acquired substantial skills and experience in such
business; (c) will receive substantial consideration and proceeds as a result of the transactions contemplated by the Merger Agreement;

Company plans to continue to engage in its business as currently conducted; and (iii) competition by the Restricted Party,

the Restricted Party agrees to the covenants in this Section 1.


 






    


     


    

 


            1.2        Covenant

not to engage, directly or indirectly, in the Protected Business (as defined below) anywhere in the world including, but not limited

a physical location, other than on behalf of the Company and Parent, their respective direct and indirect Subsidiaries and their respective
Affiliates (collectively, the “Company Group”). The term “Protected Business” means any activity
which is competitive with any of the businesses, activities, products or services conducted, developed or offered by the Company or that
the Company intends to conduct, develop or offer as of the Closing Date or any businesses, activities, products or services that the
Company engages in or intends to conduct, develop or offer immediately prior to the termination of the Restricted Party’s employment
(for any reason) with the Company. Without limiting the foregoing, the covenant in this Section 1.2 prohibits the Restricted Party

officer, trustee, executive, employee, joint venturer, agent or consultant, or in any other capacity), participating or investing in,
providing financing to or providing or facilitating the provision of financing to, or assisting, any Person (including any Person who

Protected Business.1


 


            1.3        Covenants

Party’s own account or for the account of any other Person, engage in Interfering Activities (as defined below). For the
purpose of this Agreement, the following terms shall be defined as follows:


 


                          (a)       “Business
Relation” means any current or prospective client, customer, licensee, account, supplier or other business relation
of any of the Company Group, or any such relation that was a client, customer, licensee, account, supplier, or other business

Restricted Party provided services, or with whom the Restricted Party transacted business, or whose identity became known to the
Restricted Party in connection with the Restricted Party’s relationship with the Company Group.


 


                          (b)       “Interfering
Activities” means (i) encouraging, soliciting, or inducing, or in any manner attempting to encourage, solicit, or induce,

the foregoing shall not be violated by general advertising not targeted at employees or consultants of any member of the Company
Group; or (ii) encouraging, soliciting, or inducing, or in any manner attempting to encourage, solicit, or induce, any Business
Relation to cease doing business with any of the Company Group or reduce the amount of business conducted with any of the Company

Period” twenty four (24) month anniversary of the Closing Date (as such term is defined in the Merger Agreement.


 


            1.4        Confidentiality.
The Restricted Party acknowledges that, as an employee, the Restricted Party has had and will have access to non-public information
about the Company Group and that the Restricted Party’s relationship with the Company has brought and will bring the Restricted
Party into close contact with confidential and proprietary information of the Company Group. In recognition of the foregoing,
the Restricted Party agrees at all times to hold in confidence, and not to use, except for the benefit of the Company Group, or
to disclose to any Person without written authorization of Parent, any Confidential Information that the Restricted Party obtains
or creates (whether solely or jointly with others). The Restricted Party further agrees not to make copies of such Confidential
Information except as authorized by Parent or as otherwise necessary to fulfill the Restricted Party’s duties to the Company
Group. For purposes of this Agreement, “Confidential Information” means information that the Company Group
has developed, acquired, created, compiled, discovered, or owned or will develop, acquire, create, compile, discover, or own,
that has value in or to the business of the Company Group that is not generally known and that Parent wishes to maintain as confidential,
including, without limitation, any and all non-public information that relates to the actual or anticipated business and/or products,
research, or development of the Company Group, or to the Company Group’s technical data, Trade Secrets, know-how, products,
services, markets, customer lists, business plans, software, developments, inventions, processes, formulas, pricing information,
technology, designs, drawings, engineering, hardware configuration information, marketing, finances, and other business information
disclosed by the Company Group either directly or indirectly in writing, orally, or by drawings or inspection of premises, parts,
equipment, or other property of the Company Group. Notwithstanding the foregoing, Confidential Information shall not include (a)
any of the foregoing items that have become publicly known through no unauthorized disclosure by the Restricted Party, (b) information
rightfully obtained by the Restricted Party from a third party with no obligation to keep confidential, (c) general information
or knowledge of the Company’s industry, or (d) any information that the Restricted Party is required to disclose to any
governmental or judicial authority; provided, however, that in such event the Restricted Party will give Parent
prompt written notice thereof so that Parent may seek an appropriate protective order and/or waive in writing compliance with
the confidentiality provisions of this Section 1.4. In addition, notwithstanding the foregoing nondisclosure obligations,
pursuant to 18 U.S.C. Section 1833(b), the Restricted Party will not be held criminally or civilly liable under any federal or
state Trade Secret law for the disclosure of a Trade Secret that is made: (1) in confidence to a federal, state, or local government
official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected
violation of law; or (2) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under
seal.

             1.5        Non-Disparagement.
The Restricted Party will not make any comments intended to be disparaging or defamatory regarding any member of the Company
Group or, to the extent they are known to the Restricted Party as associated with any of the Company Group, regarding their respective
current or former directors, managers, stockholders, partners, members, managers, officers, or employees. Notwithstanding the
foregoing, the Restricted Party’s obligations under this Section 1.5 shall not apply to disclosures required
by applicable Law, regulation, or order of a court or governmental agency or to any statements made in the performance of the
Restricted Party’s duties for any member of the Company Group. Likewise, nothing herein shall interfere with any right which
may be conferred to the Restricted Party under Section 7 of the National Labor Relations Act.


 


             1.6        Savings
Clause. In addition to the provisions of Section 14, it is the desire and intent of the Parties that the provisions
of this Section 1 shall be enforced to the fullest extent permissible under applicable Law. If any provision of this Section
1, or any part of any such provision, is held under any circumstances to be invalid or unenforceable by any arbitrator or
court of competent jurisdiction, then: (a) such provision or part thereof shall, with respect to such circumstances and in
such jurisdiction, be modified by such arbitrator or court to conform to applicable Law so as to be valid and enforceable to the
fullest possible extent; (b) the invalidity or unenforceability of such provision or part thereof under such circumstances and
in such jurisdiction shall not affect the validity or enforceability of such provision or part thereof under any other circumstances
or in any other jurisdiction; and (c) the invalidity or unenforceability of such provision or part thereof shall not affect the
validity or enforceability of the remainder of such provision or the validity or enforceability of any other provision of this
Section 1. Each provision of this Section 1 is separable from every other provision of this Section 1, and
each part of each provision of this Section 1 is separable from every other part of such provision.


 


             1.7        Permitted
Activities. Notwithstanding anything to the contrary in Section 1.2 above, the Restricted Party may manage and
make passive investments of the Restricted Party’s personal assets and those of the Restricted Party’s family members
in publicly traded securities of a company not to exceed one percent (1%) of the total number of that company’s outstanding
securities of that same class, so long as the Restricted Party has no active participation or involvement in the business of such
company.


 


             1.8        Reasonableness
of Terms. The Restricted Party acknowledges that the duration of the Restricted Period and the scope of the Protected
Business which the restrictions imposed in this Section 1 shall apply are fair and reasonable and are reasonably required
to protect the goodwill, customer relationships, Trade Secrets and stable workforce of the Company.


 


2.          Consideration.
In consideration for the representations, warranties, and covenants contained herein, Parent agrees to pay (or cause to be paid)
to the Restricted Party the sum of US$100. The Restricted Party acknowledges and agrees that the Restricted Party is not otherwise
entitled to receive the aforesaid payment absent the Restricted Party’s agreement to the representations, warranties, and
covenants set forth in this Agreement.

3.         Representations
by the Restricted Party. The Restricted Party represents and warrants to Parent that: (a) the Restricted Party is familiar

restrictions imposed on the Restricted Party under this Agreement are fair, reasonable and required for the protection of the
Company’s business interests, goodwill, and business relationships with its current and prospective clients and customers;

in Section 1 and in the other provisions of this Agreement; (e) the execution of this Agreement, and performance
of the Restricted Party’s obligations under this Agreement, will not conflict with, or result in a violation or breach of,
any other agreement to which the Restricted Party is a party or bound as of the Closing Date or any applicable Law, judgment,
order or decree to which the Restricted Party is subject; (f) the Restricted Party has all necessary capacity, right, power and
authority to enter into and perform this Agreement, and this Agreement is a valid and legally binding obligation of the Restricted
Party, enforceable against the Restricted Party in accordance with its terms, except as the same may be limited by applicable
bankruptcy, insolvency, moratorium or similar applicable Law affecting creditors’ rights generally or by general equitable
principles affecting the enforcement of contracts; and (g) the Restricted Party’s compliance with the covenants set forth
herein will not create significant hardship for the Restricted Party as the Restricted Party has independent means and sufficient
income without violating any such covenants for the periods set forth herein.


 


4.         Breach.
The Restricted Party hereby acknowledges that in the event of a breach by the Restricted Party of any of the provisions of
this Agreement, Parent, the Company and/or their respective successors or assigns could sustain irreparable harm, and, therefore,
the Restricted Party agrees that, in addition to any other remedies that Parent may have under this Agreement, the Merger Agreement,
any other Additional Document or otherwise, Parent shall be entitled to equitable relief, including, without limitation, specific
performance, temporary restraining orders, and preliminary and permanent injunctive relief restraining the Restricted Party from
committing or continuing any such violation of this Agreement and the Restricted Party agrees to waive any requirements for the
securing or posting of any bond in connection with such remedy. In addition, in the event of a breach or violation by the Restricted
Party of the restrictions contained in Section 1 of this Agreement, the Restricted Period shall be tolled until such breach
or violation has been duly cured.


 


5.         Entire
Agreement. This Agreement, together with the applicable provisions of the Merger Agreement and the other Additional Documents
applicable to the Restricted Party (including, without limitation, the Restricted Party’s Employment Agreement, dated as
of the date hereof, with the Company), is the product of both Parties and constitutes the entire agreement between the Parties
pertaining to the subject matter hereof, and supersedes all prior negotiations and drafts of the Parties with regard to the transactions
contemplated herein.


 


6.         Amendments.
No term of this Agreement may be amended or waived without the written consent of the Restricted Party and Parent. Any amendment
or waiver effected in accordance with this Section 6 shall be binding upon the Parties and their respective permitted successors
and assigns.


 






    5


     


    

 


7.         Successors
and Assigns. Because the obligations of this Agreement are personal in nature to the Restricted Party, the Restricted
Party agrees not to assign, sell, transfer, delegate, or otherwise dispose of, whether voluntarily or involuntarily, or by operation
of law, any rights or obligations under this Agreement, and any such purported assignment, sale, transfer, delegation or other
disposition shall be null and void ab initio. Parent may assign its rights hereunder to any of its Affiliates without the
consent of the Restricted Party. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon
the respective permitted successors and assigns of the Parties. If Parent, the Company or the Business is sold, reorganized or
otherwise transferred to another Person, it is intended that (a) Parent may provide that this Agreement will be assigned to, and
assumed by, the acquiror of such assets or equity, it being agreed that in such circumstances, the Restricted Party’s consent
will not be required in connection therewith, and (b) the covenants and undertakings set forth in this Agreement shall remain
in effect with respect to any portion of Parent’s or the Company’s business that is retained by Parent, as applicable,
as well as any portion that is so transferred and, to that end, the term “Parent” in this Agreement shall include

that would cause the application of the Law of any jurisdiction other than the State of Delaware.


 


10.       Waiver
of Jury Trial; Jurisdiction. EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY
ACTION, SUIT OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES (WHETHER ARISING IN CONTRACT, TORT
OR OTHERWISE) ARISING OUT OF, CONNECTED WITH, OR RELATED OR INCIDENTAL TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY

any rule of law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the

14.       Severability.
If any provision of this Agreement is determined to be invalid, illegal or unenforceable, the remaining provisions of this
Agreement, to the fullest extent permitted by law, shall remain in full force and effect. Without limiting the generality of the
foregoing, the Parties intend that the covenants contained in Section 1.2 and Section 1.3 shall be construed as
a series of separate covenants. If, in any judicial proceeding (or arbitration, as the case may be), a court (or applicable arbitrator)
shall refuse to enforce any of such separate covenants (or any part thereof) as written, then such covenant shall be enforced
to the fullest extent permitted by applicable Law, or if such covenant (or such part) shall be determined to be unenforceable
in its entirety, it shall be deemed eliminated from this Agreement for the purpose of those proceedings to the extent necessary
to permit the remaining separate covenants (or portions thereof) to be enforced by such court (or applicable arbitrator). It is
the intent of the Parties that the covenants set forth in this Agreement be enforced to the maximum extent permitted by applicable
Law.


 


15.       Third-Parties.
Except as expressly provided in this Agreement, nothing in this Agreement, express or implied, is intended to confer upon
any party, other than the Parties and their respective successors and permitted assigns, any rights under this Agreement.

all of which shall constitute one agreement. This Agreement shall become effective upon delivery to each Party of an executed
counterpart or the earlier delivery to each Party of original, photocopied, or electronically transmitted signature pages that
together (but need not individually) bear the signatures of the Parties.
