 Exhibit 10.23 
 Without Prejudice and Subject to Contract 
 THIS AGREEMENT is
made on the 12th August 2013 (Execution Date)

  

	1.	THE PARTIES 

  

	 	1.1	The Company:         Mavenir Systems UK Limited 

 

	 	    	whose address is New Century Place, 20/22 Queen’s Road, Reading, Berkshire RG1 4AU (and as agent for any and all Group companies and is duly authorised in that
behalf) 

  

	 	1.2	The Employee:         Matt Dunnett 

 whose address is 13 Brudenell, Windsor, Berkshire SL4 4UR 
  

	2.	THE BACKGROUND 

 The Employee is employed by the Company under the terms of a contract dated
17th April 2012, headed “Statement of Main Terms
of Employment.” The Employee’s employment with the Company will terminate on 4th October 2013, (“the Termination Date”). 
  

	 	2.1	Within this Agreement the words “Group Company” shall mean any company which from time to time is a subsidiary or a holding company of the Company or a
subsidiary of such holding company and “subsidiary” and “holding company” have the meanings attributed to them by section 1159 of the Companies Act 2006 or any modification or statutory re-enactment of the same.

  

	 	2.2	This Agreement records the entire agreement pursuant to which the Company and the Employee have agreed to settle all claims that the Employee has or may have against
the Company or any officer or employee of the Company or against any Group Company or any officer or employee of any such Group Company as stated in Clause 4.1 herein. No variation to these terms is valid unless set out in writing and signed by the
Employee and the Company. 

	 	2.3	 The Employee will spend the period from 12th August until the Termination Date on garden leave pursuant to paragraph 9.4 of the Company’s Employee
Handbook. During this period the Employee will not attend the Company’s offices or carry out any duties for the Company, unless specifically requested to do so by the Company, but will be available to answer any queries during this time and
will notify the Company or any planned holiday dates. During the garden leave period, the Employee will not have business dealings with the Company’s employees, customers or potential customers, agents or distributors and will not take up any
other office, employment, consultancy or partnership, or trade on his own account, (referred to collectively as “Other Business Interests), without the Company’s prior written consent. During the garden leave period the Employee’s
implied duties of loyalty and good faith shall continue to apply and on no account may he undertake any activities which compete directly or indirectly with the Company or any Group Company. Prior to commencing his period of garden leave, the
Employee will co-operate with the Company in an orderly handover of his duties and responsibilities to such person or persons as the Company may direct and shall advise the Company of any passwords that he has used on the Company’s computer
systems. 

  

	 	2.4	 The Company confirms that the Employee’s salary in respect of the period up to and including the Termination Date will be paid via the normal
August, September and October 2013 payrolls on or around
20th each month subject to all necessary deductions for
income tax and employee National Insurance Contributions, and also agrees to maintain all the Employee’s contractual benefits up to the Termination Date. By the Termination Date the Employee will have taken more holiday than the amount that
would have accrued to him. Therefore he will not be due a payment in respect of accrued but untaken holiday 

	 	on termination of employment. The Company will however waive its rights to seek repayment in respect of holiday taken in excess of the Employee’s accrued
entitlement. The Employee will continue to be covered by the Company’s private medical plan until 31st December 2013. 

  

	 	2.5	 The Company confirms that the Employee will be eligible for commission on any orders booked for the International region up to 4th October 2013 and cash collection payments on booked orders for
the International region up to 31st December 2013 in
accordance with and subject always to the rules of the 2013 Sales Commission Plan (“the Plan”). Commissions may be reduced, or extinguished in accordance with the said rules in the event of sales credits, cancellations, returns or other
adjustments of customer orders as provided for in the Plan and the provisions of the Plan dealing with the same and with any repayments of commission from employees who have left the Company shall continue to apply to the Employee.

  

	3.	AGREEMENT BY THE COMPANY 

  

	 	3.1	The Company hereby agrees to pay to the Employee as compensation for loss of office and in full and final settlement of the particular complaints set out in Clause 4.1
herein: 

  

	 	3.1.1	The sum of £49,500 within the period of thirty days after the Termination Date. The payment referred to in Clause 3.1.1 above shall be made (after the Employee
has been provided with his P45), without deduction of income tax or National Insurance Contributions in relation to the first £30,000 of the payment, the balance being subject to deduction of tax at the OT rate or such other subsequent tax
withholding requirements as required by the Income Tax (Earnings and Pensions) Act 2003 or any modification or statutory re-enactment of the same. The Employee will assume responsibility for the payment of any further tax due and shall account to HM
Revenue and Customers in due course for such tax. 

	 	3.2	A condition of the payment referred to in Clause 3.1.1 is that any liability to income tax or employee’s National Insurance Contributions in respect of the first
£30,000 of this payment and in relation to the other sums paid to the Employee pursuant to this agreement (save where the Employer has agreed to make deductions at source prior to payment to the Employee), shall be the responsibility of the
Employee who agrees to indemnify and keep the Company indemnified on demand in respect of such income tax or employee National Insurance Contributions (including any interest or penalties or associated costs). It shall be a condition precedent to
the indemnity that the Company agrees to promptly notify the Employee of any claim for income tax or employee national insurance and shall provide the Employee with reasonable assistance (excluding financial assistance but including, if required,
the provision of any relevant documentation) in order to enable the Employee to dispute any claim for income tax and the Company further undertakes not to make any payment of income tax or employee national insurance without allowing the Employee a
reasonable opportunity to dispute any such claim with HM Revenue & Customs or relevant authorities at his own cost. 

  

	 	3.3	 The Company and Employee agree that as of the Termination Date the Employee will hold options to purchase an aggregate of 300,000 shares of the
Company’s Common Stock, 0.001 par value per share and will be vested in and have the right to purchase 175,000 shares of the Company’s Common Stock as of October 4, 2013 pursuant to a Stock Option Agreements dated as December 13,
2011, by and between the Company and Employee (the “Option Agreement”). As part consideration for the Employee’s execution of this Agreement, the Company agrees that on the Termination Date Employee shall vest in and have the right to
exercise an additional 18,750 shares of its Common Stock pursuant to the Option Agreement that would otherwise 

	 	remain unvested and unexercisable, for a total of 193,750 shares of Common Stock exercisable pursuant to the Option Agreement. Furthermore, the Company agrees that the
period the Employee has to exercise each such option is extended until June 30th 2014. The Employee acknowledges that any shares of Common Stock acquired by the Employee upon exercise of the Option Agreement shall continue to be subject to the 2005 Stock Plan and the Company’s
right of first refusal in the Option Agreement and the other restrictions on transfer set forth therein. 

  

	 	3.4	The Company will reimburse the Employee for any outstanding business expenses properly due to him from the Company in accordance with the Company’s expense claim
arrangements, subject to the Employee presenting a claim to the Company by the Termination Date together with all vouchers and receipts that the Company may reasonably require. 

 

	 	3.5	The Company will pay to THOMAS MANSFIELD, the Employee’s Solicitors, as Qualified Lawyers, a sum not exceeding £350 plus VAT as a contribution towards the
legal costs incurred by the Employee for advice as to the terms and effect of this Agreement, within fourteen days of receipt of an appropriate invoice from the Employee’s Solicitors addressed to the Employee, marked payable by the Company and
the Company’s receipt of two copies of this Agreement signed by the Employee with the Certificate attached to this Agreement at Schedule 1 signed by the Qualified Lawyer. 

	4.	IN FULL AND FINAL SETTLEMENT 

  

	 	4.1	The terms of this Agreement are without admission of liability on the part of the Company or any Group Company and are in full and final settlement of all claims,
whether contractual, statutory or otherwise, which the Employee has against the Company or any officer or employee of the Company or against any Group Company or any officer or employee of any Group Company, arising out of or in connection with the
Employee’s employment or its termination, and without prejudice to the generality of the foregoing, including but not limited to the claims stated in the Sub-Clauses of this Clause 4.1 under English and/or European law and all subsequent
amending legislation (the particular complaints) and including any future claims arising between the date of this Agreement and the Termination Date: 

  

	 	4.1.1	Any claim for breach of contract including but not limited to any claim in relation to the giving of notice, or payment in lieu of notice, or in relation to wages and
future earnings, including holiday pay, commission and/or any claim in relation to any other type of bonus, benefit, carve out payment or provision (whether provided by the Company or any Group company), including Company funded healthcare, life
insurance contributions and pension contributions and/or any claim in relation to wrongful dismissal; 

  

	 	4.1.2	Any claim for unfair dismissal. 

  

	 	4.1.3	Any other claim arising out of any contravention or alleged contravention of the Employment Rights Act 1996 including but not limited to any claim in relation to Part
II (Protection of Wages) and Part IX (Termination of Employment); 

  

	 	4.1.4	Any claim related to working time, rest periods or breaks or annual leave under the Working Time Regulations 1998. 

 

	 	4.1.5	Any claim relating to grievance or grievance procedure (and the Employee hereby acknowledges that he does not have any outstanding grievances against the Company or any
Group Company) 

	 	4.1.6	Any claim for discrimination or harassment on grounds of, or related to, sex, race, nationality, ethnic origins, marital status, disability, religion, belief, sexual
orientation age, or transsexuality, whether under the Equality Act 2010 or otherwise 

  

	 	4.1.7	Any claim relating to less favourable treatment, discrimination or harassment by reason of part-time or fixed term status

	 	4.1.9	Any claim relating to the Employer’s or any Group Company’s shares or securities, including claims relating to any share option scheme operated by or on
behalf of the Employer or any Group Company but subject to clause 3.3 above. 

 The Employee has either asserted
the above claims prior to entering into this Agreement, (and does now assert and agrees to settle under this Agreement a claim for unfair dismissal), or where such claims have not been asserted, the Employee represents to the Employer and the
Employer relies on this representation in entering into this Agreement, that, having taken independent legal advice, the Employee is not aware of any facts or matters which might give rise to any such claims. 

 

	 	4.2	This Agreement does not settle any claim for latent personal injury whether mental or physical unrelated to the termination of the Employee’s employment or any
alleged act of discrimination, of which the Employee is unaware at the date of this Agreement. 

  

	 	4.3	This Agreement does not affect any accrued rights that the Employee may have in respect of the Company’s pension scheme arrangements. 

	 	4.4	 The Employee will return to the Company by the 12th August 2013 any property belonging to the Company or any Group Company which is in his possession, custody or
control including but not limited to any SIM cards, access cards or blackberries, mobile phones, laptop and any other equipment provided to the Employee by the Company together with all papers, correspondence, documents, files, databases or other
data whatsoever (whether held on computer or in hardcopy) belonging to the Company, or any Group Company or relating to their respective affairs, including but not limited to customer and price lists and customer contracts and will not retain copies
of the same. 

  

	 	4.5	From the Termination Date the Employee will not represent himself or permit himself to be held out as being in any way connected with or interested in the Company.

  

	 	4.6	The Employee will keep this Agreement confidential and will not disclose the existence of this Agreement or any of its terms to any person, save (a) to his
immediate family, or to his professional advisers for the purposes of receiving professional advice concerning this Agreement or for the purpose of enforcing any term of this Agreement, in which event the person or persons to whom such disclosure is
made will have drawn to their attention by the Employee the terms of this confidentiality clause and shall themselves be instructed by the Employee to maintain such confidentiality, or (b) as may be required by law, and save that nothing in
this Agreement shall prevent the Employee from disclosing to third parties that his employment terminated by reason of mutual agreement. 

  

	 	4.7	 In consideration of the payment by the Company to the Employee within the period of fourteen days after the Termination Date of £100 (less
deductions for tax and employee’s National Insurance Contributions) the Employee agrees to abide by those provisions of his contract of employment with the Company that are expressed to apply following the termination of his employment,
including but not limited to 

	 	the clauses headed Confidential Information, Inventions/Intellectual Property, Non Solicitation/Employment of Employees, Non Solicitation/Dealing with Customers and the

limited to company strategy information, product portfolio information and roadmaps, budgets, management accounts, bank account details, sales statistics, price lists, customer lists, marketing and sales collateral and other confidential financial
and customer data of the Company’s and the terms on which the Company or any Group Company employs or engages employees, officers and contractors or trades with customers and other third parties, The confidentiality clause will not restrict the
Employee from making “protected disclosures” within the meaning of the Public Interest Disclosure Act 1998. 

  

	 	4.8	The Employee represents that he has not committed any act of gross misconduct of which the Employer is unaware and which, if disclosed, would have entitled the Employer
to summarily dismiss him. 

  

	 	4.9	The Company undertakes on its own behalf and on behalf of its officers and employees to keep the circumstances leading up to the termination, this Agreement and all
terms of this Agreement confidential save for the purpose of enforcing any term of this Agreement or as may be required by law. Furthermore the Company undertakes, if asked, to inform any third party that the Employee’s employment was
terminated by mutual agreement. 

  

	 	4.10	The Employee agrees that he will not make any disparaging comments whether orally or in writing about the Employer, any Group Company or any of their respective
officers or employees. The Employer will procure that its officers and those of its employees who have been involved in the preparation and negotiation of this Agreement, will not make any disparaging comments whether orally or in writing about the
Employee. 

	 	4.11	For the avoidance of doubt if, contrary to the views of the parties, the claims set out in clause 4.1 above have not been validly and lawfully excluded by the
provisions of this Agreement, and the Employee institutes legal proceedings in respect of any of them, then all sums paid by the Company pursuant to clause 3.1 of this Agreement, shall be immediately repayable by the Employee to the Company as a
debt and the agreement to reduce the duration of the Employee’s Covenant Not to Compete shall no longer apply. Without prejudice to the foregoing, the Employee agrees to indemnify and keep indemnified the Company, any Group Company and any
officer or employee of the Company or any Group Company against whom the Employee commences legal proceedings, against all claims, costs, demands, compensation, damages or interest, together with legal costs on a full indemnity basis, incurred by
the Company, or such officer or employee, in any such legal proceedings instituted by the Employee 

  

	 	4.12	The Employee hereby warrants to the Company that he has received independent legal advice from the Qualified Lawyer as to the terms and effects of this Agreement under
English law prior to his executing the same and in particular, as to its effect on the Employee’s ability to pursue any of the rights or claims set out in clause 4.1 of this Agreement 

 

	 	4.13	For the avoidance of doubt, notwithstanding that this Agreement is marked “Without Prejudice and Subject to Contract” on its first page, the without prejudice

 2. Confidential Information. 
 (a) Company Information. I agree at
all times during the term of my employment and thereafter to hold in strictest confidence, and not to use, except for the benefit of the Company, any of the Company’s Confidential Information; or disclose to any person, firm or corporation any
of the Company’s Confidential Information except as authorized in writing by the Company’s Board of Directors or, if expressly authorized by the Company’s management, pursuant to a written nondisclosure agreement that sufficiently
protects the Confidential Information. I understand that “Confidential Information” means any information that relates to the Company’s actual or anticipated business or research and development, technical data, trade secrets
or know-how, including, but not limited to, research, product plans or other information regarding the Company’s products or services and markets therefor, customer lists and customers (including, but not limited to, the Company’s

(a) Inventions Retained and Licensed. I have attached hereto as Exhibit A is a list describing all inventions, original
works of authorship, developments, improvements and trade secrets that were made by me prior to my employment with the Company, relate to the Company’s proposed business, products or research and development, and are owned in whole or in part
by me, (“Prior Inventions”); or, if no such list is attached or if Exhibit A is unsigned, I represent that there are no such Prior Inventions. I agree that I will not incorporate, or permit to be incorporated, any Prior
Invention into a Company product, process or service without the Company’s prior written consent. Nevertheless, if, in the course of my employment with the Company, I incorporate into a Company product, process or service a Prior Invention, I
hereby grant to the Company a nonexclusive, royalty-free, fully paid-up, irrevocable, perpetual, transferable, sublicensable, worldwide license to reproduce, make derivative works of, distribute, perform, display, import, make, have made, modify,
use, sell, offer to sell, and exploit in any other way such Prior Invention as part of or in connection with such product, process or service, and to practice any method related thereto. 

(b) Assignment of Inventions. I agree that I will promptly make full written disclosure to the Company, will hold in trust for the
sole right and benefit of the Company, and hereby assign to the Company, or its designee, all my right, title, and interest in and to any and all inventions, original works of authorship, developments, concepts, improvements, designs, discoveries,
ideas, trademarks or trade secrets, whether or not patentable or registrable under copyright or similar laws, which I may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice,
during the period of time I am in the employ of the Company (collectively, “Inventions”), except as provided in Section 3(f) below. I further acknowledge that all original works of authorship which are made by me (solely or
jointly with others) within the scope of and during the period of my employment with the Company and which are protectable by copyright are “works made for hire” as that term is defined in the United States Copyright Act. I understand and
agree that the decision whether or not to commercialize or market any Invention is within the Company’s sole discretion and for the Company’s sole benefit and that no royalty will be due to me as a result of the Company’s efforts to
commercialize or market any such Invention.

United States government all my right, title, and interest in and to any and all Inventions whenever such full title is required to be in the United States by a contract between the Company and the United States or any of its agencies. 

(d) Maintenance of Records. I agree to keep and maintain adequate, current, accurate, and authentic written records of all
Inventions made by me (solely or jointly with others) during the term of my employment with the Company. The records will be in the form of notes, sketches, drawings, electronic files, reports, or any other format that may be specified by the
Company. The records are and will be available to the Company and shall remain the Company’s sole property at all times. 

(e) Patent and Copyright Registrations. I agree to assist the Company, or its designee, at the Company’s expense, in every
proper way to secure the Company’s rights in any Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto in any and all countries, including, but not limited to, the disclosure to the
Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments that the Company deems necessary in order to apply for and obtain such rights and in
order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights
relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after the termination of this Agreement. If the Company is unable because of my
mental or physical incapacity or for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering any Inventions or original works of authorship
assigned to the Company as above, then I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for and in my behalf and stead to execute and file any such
applications and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed by me. 

  
 - 2 -

 (f) Exception to Assignments. I understand that the provisions of this Agreement
requiring assignment of Inventions to the Company do not apply to any Invention that I have developed entirely on my own time without using the Company’s equipment, supplies, facilities, trade secret information or Confidential Information (an
“Other Invention”) except for those Other Inventions that either (i) relate at the time of conception or reduction to practice of such Other Invention to the Company’s business, or actual or demonstrably anticipated
research or development of the Company or (ii) result from any work that I performed for the Company. I will advise the Company promptly in writing of any Invention that I believe constitutes an Other Invention and is not otherwise disclosed on
Exhibit A. I agree that I will not incorporate, or permit to be incorporated, any Other Invention owned by me or in which I have an interest into a Company product, process or service without the Company’s prior written consent.
Notwithstanding the foregoing sentence, if, in the course of my employment with the Company, I incorporate into a Company product, process or service an Other Invention owned by me or in which I have an interest, I hereby grant to the Company a
nonexclusive, royalty-free, fully paid-up, irrevocable, perpetual, transferable, sublicensable, worldwide license to reproduce, make derivative works of, distribute, perform, display, import, make, have made, modify, use, sell, offer to sell, and
exploit in any other way such Other Invention as part of or in connection with such product, process or service, and to practice any method related thereto. 
 4. Conflicting Employment. 
 (a) Current Obligations. I agree that,
during the term of my employment with the Company, I will not engage in any other employment, occupation or consulting related to the business in which the Company is now involved, becomes involved or has plans to become involved in during the term
of my employment, nor will I engage in any other activities that conflict with my obligations to the Company. 
 (b) Prior
Relationships. Without limiting Section 4(a) above, I represent that I have no other agreements, relationships, or commitments to any other person or entity that conflict with my obligations to the Company under this Agreement or my ability
to become employed and perform the services for which I am being hired by the Company. I further agree that if I have signed a confidentiality agreement or similar type of agreement with any former employer or other entity, I will comply with the
terms of any such agreement to the extent that its terms are lawful under applicable law. I represent and warrant that after undertaking a careful search (including searches of my computers, cell phones, electronic devices, and documents), I have
returned all property and confidential information belonging to all prior employers. Moreover, I agree to fully indemnify the Company, its directors, officers, agents, employees, investors, shareholders, administrators, affiliates, divisions,
subsidiaries, predecessor and successor corporations, and assigns for all verdicts, judgments, settlements, and other losses incurred by any of them resulting from my breach of my obligations under any agreement to which I am a party or obligation
to which I am bound, as well as any reasonable attorneys’ fees and costs if the plaintiff is the prevailing party in such an action, except as prohibited by law. 
 5. Solicitation of Employees. I agree that for a period of one (1) year immediately following the termination of my relationship with the Company for any reason, whether with or without cause,
at the option either of the Company or myself, with or without notice, I will not (either directly or indirectly, on behalf of myself or any third party) hire any of the Company’s employees, consultants or contractors or solicit, induce,
recruit or encourage any of the Company’s employees, consultants or contractors to leave their employment or terminate their relationship with the Company. 
 6. Interference. I agree that during the course of my employment and for a period of one (1) year immediately following the termination of my relationship with the Company for any reason,
whether with or without cause, at the option either of the Company or myself, with or without notice, I will not (either directly or indirectly, on behalf of myself or any third party) solicit to the detriment of the Company and/or for the benefit
of any competitor of the Company, take away or attempt to take away, in whole or in part, any customer of the Company or otherwise interfere with the Company’s customer relationships.

 7. Covenant Not to Compete. 

(a) I agree that during the course of my employment and for a period of one (1) year immediately following the termination of my
employment with the Company for any reason, whether with or without cause, at the option either of the Company or myself, with or without notice, I will not, either directly or indirectly, (i) serve as an advisor, agent, consultant, director,
employee, officer, partner, proprietor or otherwise of, (ii) have any ownership interest in (except for passive ownership of one percent (1%) or less of any entity whose securities have been registered under the Securities Act of 1933, as
amended, or Section 12 of the Securities Exchange Act of 1934, as amended) or (iii) participate in the organization, financing, operation, management or control of, any business in competition with the Company’s business in the
Territory (1) as conducted by the Company during the course of my employment with the Company or (2) planned to be conducted by the Company pursuant to a product or business plan developed prior to the termination of my employment with the
Company. “Territory” shall mean (A) all counties in the State of Texas, (B) all other states of the United States of America, (C) the European Union, (D) Asia, and (E) all other countries of the world in
which the Company is then engaged in business. In particular, “Territory” shall include such geographic areas in which (I) the Company’s products and services are then deployed, (II) the Company then has a customer or
(III) the Company then has operations or otherwise targets sales and marketing activities or conducts or has plans to conduct business during the course of my employment. 
 (b) I acknowledge that my fulfillment of the obligations contained in this Agreement, including, but not limited to, my obligation neither to use, except for the benefit of the Company, or to disclose the
Company’s Confidential Information and my obligation not to compete contained in subsection (a) above is necessary to protect the Company’s Confidential Information and to preserve the Company’s value and goodwill. I further
acknowledge the time, geographic and scope limitations of my obligations under subsection (a) above are reasonable, especially in light of the Company’s desire to protect its Confidential Information, and that I will not be precluded from
gainful employment if I am obligated not to compete with the Company during the period and within the Territory as described above. 
 (c) The covenants contained in subsection (a) above shall be construed as a series of separate covenants, one for each city, county and state of any geographic area in the Territory. Except for
geographic coverage, each such separate covenant shall be deemed identical in terms to the covenant contained in subsection (a) above. If, in any judicial or arbitration proceeding, a court or arbitrator refuses to enforce any of such separate
covenants (or any part thereof), then such unenforceable covenant (or such part) shall be eliminated from this Agreement to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced. In the event the
provisions of subsection (a) above are deemed to exceed the time, geographic or scope limitations permitted by applicable law, then such provisions shall be reformed to the maximum time, geographic or scope limitations, as the case may be, then
permitted by such law. 
 8. Acknowledgements. I acknowledge that the non-solicitation and non-competition covenants I am
providing in this Agreement are reasonable and necessary to protect the legitimate interests of the Company. I further acknowledge that my non-disclosure promises contained in this Agreement is in exchange for the Company’s promises contained
in this Agreement to provide me with confidential information and trade secrets of the Company. 
 9. Returning Company
Documents, etc. I agree that, upon separation from employment with the Company or on demand by the Company during my employment, I will immediately deliver to the Company (and will not keep in my possession, recreate or deliver to anyone else)
any and all Company property, including, but not limited to, the Company’s Confidential Information, as well as all devices and equipment belonging to the Company (including computers, handheld electronic devices, telephone equipment, and other
electronic devices), Company credit cards, records, data, notes, notebooks, reports, files, proposals, lists, correspondence (including emails and any other electronic correspondence), specifications, drawings, blueprints, sketches, materials,
photographs, charts, any other documents and property, and reproductions of any and all of the aforementioned items that were developed by me pursuant to my employment with the Company, obtained by me in connection with my employment with the
Company, or otherwise belonging to the Company, its successors, or assigns, including, without limitation, those records maintained pursuant to Section 3(e).Upon separation from employment with the Company, I agree to immediately sign and
deliver to the Company the “Termination Certification” attached hereto as Exhibit B. I also consent to an exit interview to confirm my compliance with this Section 9. I further agree to keep the Company advised of my home
and business address for a period of three (3) years after termination of my employment with the Company, so that the Company can contact me regarding my continuing obligations provided by this Agreement. 

10. Conflict of Interest Guidelines. I agree to diligently adhere to the Conflict of Interest Guidelines attached hereto as
Exhibit C. 

  
 - 4 -

 11. Further Assurances; No Conflict. I agree to execute any proper oath or verify any
proper document required to carry out the terms of this Agreement. I represent that my performance of all the terms of this Agreement will not breach any agreement to keep in confidence proprietary information acquired by me in confidence or in
trust prior to my employment by the Company. I have not entered into, and I agree I will not enter into, any oral or written agreement in conflict herewith. 
 12. Violation; Disciplinary Matters. I understand that any breach of this Agreement or violation of Company policies by me, including any unauthorized use or disclosure of Confidential Information
of the Company or any third party during my employment may lead to disciplinary action, up to and including immediate termination and may further result in legal action by the Company. 

13. Notification to New Employer. In the event that I leave the employ of the Company, I hereby grant consent to notification by
the Company to my new employer about my rights and obligations under this Agreement. 
 14. Arbitration and Equitable
Relief. 
 (a) Arbitration. In consideration of my employment with the Company, its promise to arbitrate all
employment-related disputes and my receipt of the compensation, pay raises and other benefits paid to me by the Company, at present and in the future, I agree that, except as provided in subsection (b) below, any and all controversies, claims,
or disputes with anyone (including the Company and any employee, officer, director, shareholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from my employment with the Company or
the termination of my employment with the Company, including any breach of this Agreement, shall be subject to binding arbitration shall be settled by arbitration to be held in Dallas, Texas in accordance with the rules then in effect of the
American Arbitration Association. Disputes which I agree to arbitrate, and thereby agree to waive any right to a trial by jury, include any statutory claims under state or federal law, including, but not limited to, claims under Title VII of the
Civil Rights Act of 1964, the Americans With Disabilities Act of 1990, the Age Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act, the Texas Fair Employment and Housing Act, the Texas Labor Code, claims of harassment,
discrimination or wrongful termination and any statutory claims. I further understand that this Agreement to arbitrate also applies to any disputes that the Company may have with me. 

(b) Procedure. I agree that any arbitration will be administered by the American Arbitration Association (“AAA”)
and that a neutral arbitrator will be selected in a manner consistent with its National Rules for the Resolution of Employment Disputes. I agree that any arbitration under this section shall be conducted in Dallas, Texas. The arbitration proceedings
will allow for discovery according to the AAA National Rules for the Resolution of Employment Disputes. I agree that the arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for
summary judgment and/or adjudication and motions to dismiss and demurrers, prior to any arbitration hearing. I agree that the arbitrator shall issue a written decision on the merits. I also agree that the arbitrator shall have the power to award any
remedies, including attorneys’ fees and costs, available under applicable law. I understand the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that I shall pay the first $200.00 of any filing
fees associated with any arbitration I initiate. I agree that the arbitrator shall administer and conduct any arbitration in a manner consistent with the AAA’s National Rules for the Resolution of Employment Disputes. 

(c) Remedy. Arbitration shall be the sole, exclusive and final remedy for any dispute between me and the Company. Accordingly,
neither I nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding the foregoing, the arbitrator will not have the authority to disregard or refuse to enforce any lawful company
policy, and the arbitrator shall not order or require the Company to adopt a policy not otherwise required by law which the Company has not adopted. 
 (d) Equitable Remedies. I agree that it would be impossible or inadequate to measure and calculate the Company’s damages from my breach of Sections 2, 3, 5, 6 and 7 of this Agreement.
Accordingly, I agree that if I breach any such Section, the Company will have available, in addition to any other right or remedy available, the right to obtain an injunction from a court of competent jurisdiction restraining such breach or
threatened breach and to specific performance of any such provision of this Agreement. I further agree that no bond or other security shall be required in obtaining such equitable relief and I hereby consent to the issuance of such injunction and to
the ordering of specific performance.

 (e) Administrative relief. I understand that this Agreement does not prohibit me from
pursuing an administrative claim with a local, state or federal administrative body such as the Equal Employment Opportunity Commission or the Workers’ Compensation Commission. This Agreement does, however, preclude me from pursuing court
action regarding any such claim. 
 (f) Voluntary nature of agreement. I acknowledge and agree that I am executing this
Agreement voluntarily and without any duress or undue influence by the Company or anyone else. I further acknowledge and agree that I have carefully read this Agreement and that I have asked any questions needed for me to understand the terms,
consequences and binding effect of this Agreement and fully understand it, including that I AM WAIVING MY RIGHT TO A JURY TRIAL. Finally, I agree that I have been provided an opportunity to seek the advice of an attorney of my choice before signing
this Agreement.

the Company and me relating to the subject matter herein and supersedes all prior discussions or representations between us, including, but not limited to, any representations made during my interview(s) or relocation negotiations, whether written
or oral, and any previously executed proprietary information agreements. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing signed by the Company’s Chief
Executive Officer or President and me. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement.

representatives and will be for the benefit of the Company, its successors and its assigns.

the Company. The following are potentially compromising situations which must be avoided. Any exceptions must be reported to the Chief Executive Officer or President and written approval for continuation must be obtained 

1. Revealing confidential information to outsiders or misusing confidential information. Unauthorized divulging of information is a
violation of this policy whether or not for personal gain and whether or not harm to the Company is intended. (The Employment, Confidential Information, and Invention Assignment Agreement elaborates on this principle and is a binding agreement.)

 2. Accepting or offering substantial gifts, excessive entertainment, favors or payments which may be deemed to constitute
undue influence or otherwise be improper or embarrassing to the Company. 
 3. Participating in civic or professional
organizations that might involve divulging confidential information of the Company. 
 4. Initiating or approving personnel
actions affecting reward or punishment of employees or applicants where there is a family relationship or is or appears to be a personal or social involvement. 
 5. Initiating or approving any form of personal or social harassment of employees. 

6. Investing or holding outside directorship in suppliers, customers, or competing companies, including financial speculations, where
such investment or directorship might influence in any manner a decision or course of action of the Company. 
 7.
Borrowing from or lending to employees, customers or suppliers. 
 8. Acquiring real estate of interest to the Company.

 9. Improperly using or disclosing to the Company any proprietary information or trade secrets of any former or concurrent
employer or other person or entity with whom obligations of confidentiality exist. 
 10. Unlawfully discussing prices, costs,
customers, sales or markets with competing companies. 
 11. Making any unlawful agreement with distributors with respect to
prices. 
 12. Improperly using or authorizing the use of any inventions which are the subject of patent claims of any other
person or entity. 
 13. Engaging in any conduct which is not in the best interest of the Company. 

Each officer, employee and independent contractor must take every necessary action to ensure compliance with these guidelines and to
bring problem areas to the attention of higher management for review. Violations of this conflict of interest policy may result in discharge without warning.
