 (h)    No Inconsistent Actions. The Parties hereto

(i)    Construction. This Secondment Agreement shall be deemed drafted equally by all Parties. Its language shall

to affect construction or interpretation. Any references to paragraphs, subparagraphs, sections or subsections are to those parts of this Secondment Agreement, unless the context clearly indicates to the contrary. Also, unless the context clearly
indicates to the contrary, (a) the plural includes the singular and the singular includes the plural; (b) “and” and “or” are each used both conjunctively and disjunctively; (c) “any,” “all,”
“each,” or “every” means “any and all,” and “each and every”; (d) “includes” and “including” are each “without limitation”; (e) “herein,” “hereof”
“hereunder” and other similar compounds of the word “here” refer to the entire Secondment Agreement and not to any particular paragraph, subparagraph, section or subsection; and (f) all pronouns and any variations thereof
shall be deemed to refer to the masculine, feminine, neuter, singular or plural as the identity of the entities or persons referred to may require. 

(j)    Arbitration. Any controversy, claim or dispute arising out of or relating to this Secondment Agreement,
shall be settled solely and exclusively by a binding arbitration process administered by JAMS/Endispute in New York, New York. Such arbitration shall be conducted in accordance with the then-existing JAMS/Endispute Rules of Practice and Procedure,
with the following exceptions if in conflict: (a) one arbitrator who is a retired judge shall be chosen by JAMS/Endispute; (b) each Party to the arbitration will pay an equal portion of the expenses and fees of the arbitrator, together
with other expenses of the arbitration incurred or approved by the 

 
arbitrator; and (c) arbitration may proceed in the absence of any Party if written notice (pursuant to the JAMS/Endispute rules and regulations) of the proceedings has been given to such
Party. Each Party shall bear its own attorneys fees and expenses; provided that the arbitrator may assess the prevailing Party’s fees and costs against the non-prevailing Party as part of the arbitrator’s award. The Parties agree to abide
by all decisions and awards rendered in such proceedings. Such decisions and awards rendered by the arbitrator shall be final and conclusive. All such controversies, claims or disputes shall be settled in this manner in lieu of any action at law or
equity; provided, however, that nothing in this subsection shall be construed as precluding the bringing an action for injunctive relief or specific performance as provided in this Secondment Agreement or in the Employment Agreement. This dispute
resolution process and any arbitration hereunder shall be confidential and neither any Party nor the neutral arbitrator shall disclose the existence, contents or results of such process without the prior written consent of all Parties, except where
necessary or compelled in a court to enforce this arbitration provision or an award from such arbitration or otherwise in a legal proceeding. If JAMS/Endispute no longer exists or is otherwise unavailable, the Parties agree that the American
Arbitration Association (“AAA’) shall administer the arbitration in accordance with its then-existing rules. In such event, all references herein to JAMS/Endispute shall mean AAA. Notwithstanding the foregoing, Executive, the
Seconding Company and the Host Company each have the right to resolve any issue or dispute over intellectual property rights by court action instead of arbitration. 

(k)    Enforcement. If any provision of this Secondment Agreement is held to be illegal, invalid or unenforceable
under present or future laws effective during the term of this Secondment Agreement, such provision shall be fully severable; this Secondment Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never
comprised a portion of this Secondment Agreement; and the remaining provisions of this Secondment Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from
this Secondment Agreement. Furthermore, in lieu of such illegal, invalid or unenforceable provision there shall be added automatically as part of this Secondment Agreement a provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable. 
  

	4.	 Executive Acknowledgement. 

Executive acknowledges that Executive has read and understands this Secondment Agreement, is fully aware of its legal effect, has not acted in
reliance upon any representations or promises made by the Seconding Company or Host Company other than those contained in writing herein, has entered into this Secondment Agreement freely based on Executive’s own judgment and represents that
the Executive’s entering into this Secondment Agreement for the performance of services hereunder will not violate the tenns of any agreement or understanding, law or judicial decrce to which the Executive is subject.

	5.	 Competition. 

(a)     Executive acknowledges that the Company has provided and, during the Term, the Company from time to time will
continue to provide Executive with access to its Confidential Information (as defined below), including confidential information of third parties such as customers, suppliers, and business affiliates; specialized training and knowledge regarding the
Company’s methodologies and business strategies; and/or support in the development of goodwill such as introductions and customer relationship information. Ancillary to the rights provided to Executive as set forth in this Agreement, the
Company’s provision of Confidential Information, specialized training, and/or goodwill support to Executive, and Executive’s agreements regarding the use of same, in order to protect the value of any training, goodwill support and/or the
Confidential Information described above, the Company and Executive agree to the following provisions against unfair competition, which Executive acknowledges represent a fair balance of the Company’s rights to protect its business and
Executive’s right to pursue employment. 
 (b)     Executive shall not, within the geographic markets currently
serviced or targeted by the Company or that the Company has been involved in working towards being serviced, at any time during the Restriction Period (as defined below), directly or indirectly engage in, have any equity interest in, interview for a
potential employment or consulting relationship with or manage or operate any person, firm, corporation, partnership or business (whether as director, officer, employee, agent, representative, partner, security holder, consultant or otherwise) that
engages in any business that sells or provides products or services that are competitive (any such person, firm, corporation, partnership or business, a “Competitor”) with respect to (1) the products or services sold or
provided by the Company (or any products or services to which the Company has taken substantial steps in furtherance thereof) at any time during the period of twelve (12) months on and prior to the Date of Termination, and/or (2) any
products or services to which the Company has taken substantial steps in furtherance thereof during any portion of the Term, and such products or services are sold or provided by the Company following the Date 

 
of Termination; provided, however, that nothing herein shall prohibit Executive from being a passive owner of not more than 2% of the outstanding equity interest in any entity that is publicly
traded, so long as Executive has no active participation in the business of such entity. 
 (c)    Executive shall not,
at any time during the Restriction Period, directly or indirectly, recruit or otherwise solicit or induce any employee, customer, subscriber or supplier of the Company to (i) terminate its employment or arrangement with the Company, or
(ii) to otherwise change its relationship with the Company. Executive shall not, at any time during the Restriction Period, directly or indirectly, either for Executive or for any other person or entity, (x) solicit any employee of the Company
to terminate his or her employment with the Company, (y) employ any such individual during his or her employment with the Company and for a period of twelve months after such individual terminates his or her employment with the Company or (z)
solicit any vendor or business affiliate of the Company to cease to do business with the Company. Notwithstanding anything to the contrary in this Agreement, Executive will not be deemed to have violated this Agreement if an employee, customer,
subscriber or employee of the Company responds directly to a general advertisement of a third party as long as(1) Executive has no involvement or participation in the recruitment, solicitation or inducement of such Person, or, in the case of a
former Company employee, if such Person has not been an employee, customer, subscriber or employee of the Company for a period of twelve months at the time of any such contact with such Person, and (2) Executive in the aggregate together with
his or her affiliates does not hold more than ten percent (10%) of the outstanding voting securities of such third party and is not serving directly or indirectly as an executive officer or director of such third party. 

(d)    In the event the terms of this Section 5 shall be determined by any court of competent jurisdiction to
be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for
which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action. 

As used in this Section 5, (i) the term “Company” shall include the Company and its direct and indirect
subsidiaries or affiliates; and (ii) the term “Restriction Period” shall mean the period beginning on the Effective Date and ending on the date that is one (1) year following the Date of Termination. 

(e)    Each of the Parties (which, in the case of the Company, shall mean its officers and the members of the Board)
agrees, during the Term and for a period of three years following the Date of Termination, to refrain from Disparaging (as defined below) the other Party and its affiliates, including, in the case of the Company, any of its subsidiaries’ or
affiliates’ services, technologies or practices, or any of its directors, officers, agents, representatives or stockholders, either orally or in writing. Nothing in this paragraph shall preclude any Party from making truthful statements that
are reasonably necessary to comply with applicable law, regulation or legal process, or to defend or enforce a Party’s rights under this Agreement. For purposes of this Agreement, “Disparaging” means remarks, comments or statements
that impugn the character, integrity, reputation or abilities of the Person being disparaged. 

 (f)    Executive represents that Executive’s employment by the
Company does not and will not breach any agreement with any former employer, including any non-compete agreement or any agreement to keep in confidence or refrain from using information acquired by Executive
prior to Executive’s employment by the Company. During Executive’s employment by the Company, Executive agrees that Executive will not violate any non-solicitation agreements Executive entered into
with any former employer or improperly make use of, or disclose, any information or trade secrets of any former employer or other third party, nor will Executive bring onto the premises of the Company or use any unpublished documents or any property
belonging to any former employer or other third party, in violation of any lawful agreements with that former employer or third party. 
  

	6.	 Nondisclosure of Proprietary Information. 

(a)    Except in connection with the faithful performance of Executive’s duties hereunder or pursuant to
Section 6(c) and (e), Executive shall, in perpetuity, maintain in confidence and shall not directly, indirectly or otherwise, use, disseminate, disclose or publish, or use for Executive’s benefit or the benefit of any person, firm,
corporation or other entity (other than the Company and its affiliates) any confidential or proprietary information or trade secrets of or relating to the Company (including, without limitation, business plans, business strategies and methods,
acquisition targets, intellectual property in the form of patents, trademarks and copyrights and applications therefor, ideas, inventions, works, discoveries, improvements, information, documents, formulae, practices, processes, methods,
developments, source code, modifications, technology, techniques, data, programs, other know-how or materials, owned, developed or possessed by the Company, whether in tangible or intangible form, information
with respect to the Company’s operations, processes, products, inventions, business practices, finances, principals, vendors, suppliers, customers, potential customers, marketing methods, costs, prices, contractual relationships, regulatory
status, prospects and compensation paid to employees or other terms of employment) (collectively, the “Confidential Information”), or deliver to any person, firm, corporation or other entity any document, record, notebook, computer
program or similar repository of or containing any such Confidential Information. The Parties hereby stipulate and agree that, as between them, any item of Confidential Information is important, material and confidential and affects the successful
conduct of the businesses of the Company (and any successor or assignee of the Company). Notwithstanding the foregoing, Confidential Information shall not include any information that has been published in a form generally available to the public or
is publicly available or has become public knowledge prior to the date Executive proposes to disclose or use such information, provided, that such publishing or public availability or knowledge of the Confidential Information shall not have
resulted from Executive directly or indirectly breaching Executive’s obligations under this Section 6(a) or any other similar provision by which Executive is bound, or from any third-party breaching a provision similar to that found
under this Section 6(a). For the purposes of the previous sentence, Confidential Information will not be deemed to have been published or otherwise disclosed merely because individual portions of the information have been separately
published, but only if material features comprising such information have been published or become publicly available. 

(b)    Upon termination of Executive’s employment with the Company for any reason, Executive will promptly deliver to
the Company all correspondence, drawings, manuals, letters, 

 
notes, notebooks, reports, programs, plans, proposals, financial documents, or any other documents or property concerning the Company’s customers, business plans, marketing strategies,
products, property or processes. 
 (c)    Executive may respond to a lawful and valid subpoena or other legal process
but shall give the Company the earliest possible notice thereof, shall, as much in advance of the return date as possible, make available to the Company and its counsel the documents and other information sought and shall assist such counsel at
Company’s expense in resisting or otherwise responding to such process, in each case to the extent permitted by applicable laws or rules. 

(d)    As used in this Section 6 and Section 7, the term “Company” shall include
the Company and its direct and indirect subsidiaries or affiliates as they exist at the Date of Termination. 

(e)    Nothing in this Agreement shall prohibit Executive from (i) disclosing information and documents when required
by law, subpoena or court order (subject to the requirements of Section 6(c) above), (ii) disclosing information and documents to Executive’s attorney, financial or tax adviser for the purpose of securing legal, financial or tax
advice, (iii) disclosing Executive’s post-employment restrictions in this Agreement in confidence to any potential new employer, (iv) retaining, at any time, Executive’s personal correspondence, Executive’s personal contacts
and documents related to Executive’s own personal benefits, entitlements and obligations, or (v) using information and documents in the pursuit or defense of his rights or obligations involving the Company. 

 

	7.	 Inventions. 

All rights to discoveries, inventions, improvements, works of authorship, software, and innovations (including all data and records pertaining
thereto) related to the business of the Company, its subsidiaries or affiliates, whether or not patentable, copyrightable, registrable as a trademark, or reduced to writing, that Executive may discover, invent, conceive, author or originate during
the Term, or may have discovered, invented, conceived, authored, or originated prior to the Effective Date since the first date of his employment with the Company or any of the Company’s subsidiaries or affiliates (or their predecessors),
either alone or with others and whether or not during working hours or by the use of the facilities of the above listed entities, and any patents, copyrights, trademark rights, trade secrets rights and other intellectual property rights therein
(collectively, “Inventions”), shall be the exclusive property of the Company (or any of the Company’s subsidiaries the Company may designate). Executive shall promptly disclose all Inventions to the Company, and hereby assigns
and agrees to assign all such Inventions to the Company (or any of the Company’s subsidiaries the Company may designate). Executive shall execute at the request of the Company any assignments or other documents the Company may deem reasonably
necessary to protect or perfect its rights therein, and shall assist the Company, upon reasonable request and at the Company’s expense, in obtaining, defending and enforcing the Company’s rights (or the rights of any of the Company’s
subsidiaries or affiliates the Company may designate) therein. Executive hereby appoints the Company as Executive’s attorney-in-fact to execute on Executive’s
behalf any assignments or other documents reasonably deemed necessary by the Company to protect or perfect its rights (or the rights of any of the Company’s subsidiaries or affiliates the Company may designate) to any Inventions. 

	8.	 Injunctive Relief. 

It is recognized and acknowledged by Executive that a breach of the covenants contained in Sections 5, 6 and 7 will cause irreparable
damage to Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, Executive agrees that in the event of a breach of any of
the covenants contained in Sections 5, 6 and 7, in addition to any other remedy which may be available at law or in equity, the Company will be entitled to specific performance and injunctive relief. 

 

	9.	 Assignment and Successors. 

To the maximum extent permissible by law, the Company may assign its rights and obligations under this Agreement to any successor to all or
substantially all of the business or the assets of the Company (by merger or otherwise), and may assign or encumber this Agreement and its rights hereunder as security for indebtedness of the Company and its affiliates. This Agreement shall be
binding upon and inure to the benefit of the Company, Executive and their respective successors, assigns, personnel and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable. None of
Executive’s rights or obligations may be assigned or transferred by Executive, other than Executive’s rights to payments hereunder, which may be transferred only by will or operation of law. Notwithstanding the foregoing, Executive shall
be entitled, to the extent permitted under applicable law and applicable Company Arrangements, to select and change a beneficiary or beneficiaries to receive compensation hereunder following Executive’s death by giving written notice thereof to
the Company.

(e)    Entire Agreement. The terms of this Agreement are intended by the Parties to be the final expression of
their agreement with respect to the employment of Executive by the Company and supersede all prior understandings and agreements, whether written or oral. The Parties further intend that this Agreement shall constitute the complete and exclusive
statement of their terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of this Agreement.

provision of this Agreement that such other Party was or is obligated to comply with or perform; 

 
provided, however, that such waiver shall not operate as a waiver of, or estoppel with respect to, any other or subsequent failure. No failure to exercise and no delay in exercising any
right, remedy, or power hereunder preclude any other or further exercise of any other right, remedy, or power provided herein or by law or in equity. 

(g)    No Inconsistent Actions. The Parties hereto shall not voluntarily undertake or fail to undertake any action

provisions of this Agreement. 
 (h)    Construction. This Agreement shall be deemed drafted equally by both the
Parties. Its language shall be construed as a whole and according to its fair meaning. Any presumption or principle that the language is to be construed against any Party shall not apply. The headings in this Agreement are only for convenience and
are not intended to affect construction or interpretation. Any references to paragraphs, subparagraphs, sections or subsections are to those parts of this Agreement, unless the context clearly indicates to the contrary. Also, unless the context
clearly indicates to the contrary, (a) the plural includes the singular and the singular includes the plural; (b) “and” and “or” are each used both conjunctively and disjunctively; (c) “any,” “all,”

deemed to refer to the masculine, feminine, neuter, singular or plural as the identity of the entities or persons referred to may require. 

(i)    Jurisdiction. Any controversy, claim or dispute arising out of or relating to this Agreement, shall be
settled solely and exclusively by the competent Thai courts. 
 (j)    Enforcement. If any provision of this
Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be construed and enforced as if such illegal, invalid
or unenforceable provision had never comprised a portion of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its
severance from this Agreement. Furthermore, in lieu of such illegal, invalid or unenforceable provision there shall be added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid or unenforceable provision
as may be possible and be legal, valid and enforceable. 
 (k)    Withholding. The Company shall be entitled to
withhold from any amounts payable under this Agreement any federal, state, local or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on an opinion of counsel if any

upon any representations or promises made by 

 
the Company other than those contained in writing herein, has entered into this Agreement freely based on Executive’s own judgment and represents that the Executive’s entering into this
