NANOSTRING TECHNOLOGIES, INC. 

DAVID GHESQUIERE EMPLOYMENT AGREEMENT 

This Agreement (the “Agreement”) is entered into as of November 20, 2013 (the “Start Date”) by and between
NanoString Technologies, Inc., a Delaware corporation (the “Company”), and David Ghesquiere (“Executive”). 

1. Position. 
 (a)
Title. Executive will serve as the Sr. Vice President of Corporate and Business Development of the Company. Executive will render such business and professional services in the performance of his duties, consistent with Executive’s
position within the Company, as shall reasonably be assigned to him by the Company’s Chief Executive Officer (“CEO”) and/or Board of Directors (the “Board”). The period of Executive’s employment under this
Agreement is referred to herein as the “Employment Term” and shall commence on November 20, 2013. 
 (b)
Obligations. Executive agrees to the best of his ability and experience that he will at all times loyally and conscientiously perform all of the duties and obligations required of and from him pursuant to the express and implicit terms
hereof, and to the reasonable satisfaction of the Company. During the Employment Term, Executive further agrees that he will not engage in any other employment, occupation, consulting, or other business activity directly related to the business in
which the Company is now involved or becomes involved during the Employment Term, nor will he engage in any other activities that conflict with his obligations to the Company. Nothing in this Agreement will prevent Executive from accepting speaking
or presentation engagements in exchange for honoraria or from serving on boards of charitable organizations, or from owning no more than one percent (1%) of the outstanding equity securities of a corporation whose stock is listed on a national
stock exchange. Subject to the discretion and approval of the Company’s Board of Directors confirmed in writing by the CEO, Executive shall be free to serve on the board of directors of one corporation. 

2. At-Will Employment. The parties agree that, subject to the terms of this Agreement, Executive’s employment with the Company is
“at-will” and may be terminated at any time with or without cause or notice. Executive understands and agrees that neither his job performance nor promotions, commendations, bonuses or the like from the Company give rise to or in any way
serve as the basis for modification, amendment, or extension, by implication or otherwise, of his employment with the Company. The at-will nature of Executive’s employment cannot be modified or amended except by a written agreement signed by
Executive and the Company’s CEO. 
 3. Compensation. 

(a) Base Salary. During the Employment Term, the Company will pay Executive as compensation for his services a base salary at the
annualized rate of three hundred thousand dollars ($300,000) (the “Base Salary”). The Base Salary will be paid periodically in 

 
accordance with the Company’s normal payroll practices and be subject to the usual, required withholdings, and change at the Company’s discretion, including annual review by the Board
for any appropriate adjustment. 
 (b) Bonus. Executive shall be eligible to be considered for an annual, performance-based, cash
bonus of up to 40% of Executive’s Base Salary for each calendar year, which bonus shall be awarded in the sole discretion of the Compensation Committee of the Board of Directors based on a recommendation from the CEO, which shall be based on
Executive’s performance in the prior calendar year against metrics established for such year by the Company. Any bonus awarded shall be paid by no later than March 15 following the calendar year to which the bonus corresponds. If Executive
is terminated by or leaves the Company prior to the end of a given calendar year, then the Company shall have no obligation to pay a bonus to Executive for such year. Executive will be eligible to participate in the 2014 bonus plan effective
January 1, 2014. 
 (c) Signing Bonus. Executive shall be paid a signing bonus equal to $15,000 via a regularly scheduled
payroll that is within 30 days of the Start Date. If Executive terminates his employment with Company for any reason within one year of the Start Date the bonus will be refundable in full and may be set off against any other amounts due Executive
upon termination. 
 (d) Equity Grant. In connection with the commencement of Executive’s employment, the Company will recommend
that the Board of Directors grant Executive an option to purchase 93,000 shares of common stock of the Company (the “Stock Option”), with an exercise price equal to the fair market value on the date of grant. The Stock Option will
vest at the rate of 25% of the shares on the twelve (12) month anniversary of Executive’s Vesting Commencement Date (as defined in his Stock Option Agreement, which date will be the first day of the Employment Term) and the remaining Stock
Option shares will vest monthly thereafter at the rate of 1/48 of the total number of the Option Shares per month. Vesting will, of course, depend on Executive’s continued employment with the Company. The Stock Option will be subject to the
terms of the Company’s 2013 Equity Incentive Plan (the “Plan”). In the event that there is a Change in Control (as such term is defined in the Plan), and the Executive is terminated from employment without Cause (as defined
below) or resigns for a Good Reason (as defined below) on or within twelve (12) months after the effective date of such Change in Control, then one hundred percent (100%) of the unvested portion of the Stock Option shall vest and become
exercisable at the time of Executive’s termination from employment. The Stock Option will be subject to the terms of the Plan and a stock option agreement between Executive and the Company. 

4. Employee Benefits. During the Employment Term, Executive will be entitled to participate in the employee benefit plans currently and
hereafter maintained by the Company of general applicability to other senior executives of the Company, including, without limitation, the Company’s medical plans. The Company reserves the right to cancel or change the benefit plans and
programs it offers to its employees at any time. Executive shall also be entitled to take paid vacation consistent with the Company’s vacation policy approved by the Board. The Company shall pay or promptly reimburse Employee for all
reasonable, out-of-pocket travel and business expenses incurred in the performance of Employee’s duties on behalf of the Company for which Employee submits the required supporting documentation and otherwise fully complies with the
Company’s travel and expense reimbursement policy as in effect from time to time.

 5. Severance Benefits. 

(a) Involuntary Termination. If Executive’s employment with the Company terminates as a result of an Involuntary Termination (as
defined below), and Executive signs and does not revoke a standard release of claims with the Company within sixty (60) days after the date of his termination (the “Release Deadline), then, subject to Executive’s compliance with
Section 8, Executive shall receive severance pay (less applicable withholding taxes) at a rate equal to his Base Salary rate, as then in effect, for a period of six (6) months from the date such release of claims becomes effective (such
payments shall be paid periodically in accordance with the Company’s normal payroll policies). Severance payments under this Section 5(a) will commence on the first payroll following the Release Deadline, subject to any delay required by
Section 13. Any installment payments that would have been made to Executive during the sixty (60) day period immediately following Executive’s termination of employment but for the preceding sentence will be paid on the first payroll
following the Release Deadline and the remaining payments shall be made as provided in this Agreement. If Executive becomes entitled to receive severance pay pursuant to this Section 5(a), Executive will not be entitled to any other severance
benefits or similar payments in accordance with the Company’s established policies as then in effect. 
 (b) Voluntary Termination;
Termination for Cause. If Executive’s employment with the Company is terminated voluntarily by Executive or for Cause by the Company, then (i) all vesting of any unvested stock options or shares of restricted stock held by Executive as
of the date of Executive’s termination of employment will terminate immediately, (ii) all payments of compensation by the Company to Executive hereunder will terminate immediately (except as to amounts already earned) and
(iii) Executive will only be eligible for severance benefits in accordance with the Company’s established policies as then in effect. 

(c) Termination by Reason of Death or Disability. If Executive’s employment with the Company terminates as a result of
Executive’s death or Disability (as defined in Section 6 below), Executive or Executive’s estate or representative will receive all salary accrued (plus any other amounts payable as determined by the Board in its sole discretion) as
of the date of Executive’s death or Disability and any other benefits payable under the Company’s then existing benefit plans and policies in accordance with such plans and policies in effect on the date of death or Disability and in
accordance with applicable law. Such payments shall be made by the Company periodically in accordance with the Company’s normal payroll policies with respect to each element of such payments. 

6. Definitions. 
 (a)
Cause. For purposes of this Agreement, “Cause” is defined as (i) a violation of a material written Company policy that is communicated by the Board to Executive and that continues uncured for thirty (30) days,
(ii) an act of dishonesty made by Executive in connection with Executive’s responsibilities as an employee, (iii) Executive’s conviction of, or plea of nolo contendere to, a felony, (iv) Executive’s gross
misconduct, (v) the failure or refusal of Executive to follow the lawful and proper directives of the Board that are within the scope of the Executive’s duties set forth in Section 1 above and that is not corrected within thirty
(30) days after written notice from the Board to Executive identifying such failure or refusal or (vi) Executive’s material breach of the PIIA (as defined below) or Section 8(b) hereof. 

  
 -3- 

 (b) Disability. For purposes of this Agreement, “Disability” shall mean
that Executive has been unable to perform his duties hereunder as the result of his incapacity due to physical or mental illness, and such inability, which continues for at least 120 consecutive calendar days or 150 calendar days during any
consecutive twelve-month period, is determined to be total and permanent by a physician selected by the Company and its insurers and acceptable to Executive or to Executive’s legal representative (with such agreement on acceptability not to be
unreasonably withheld). 
 (c) Good Reason. For purposes of this Agreement, “Good Reason” shall mean if
(A) there is (1) a material, adverse and permanent change in Executive’s position as set forth in Section 1(a) of this Agreement causing such position to be of materially reduced stature or responsibility (other than changes
related to Executive’s termination as Senior Vice President of Corporate and Business Development (2) a reduction of more than five percent (5%) in Executive’s Base Salary then in effect (other than any such reduction applicable
to officers of the Company generally), (3) a material reduction by the company in the kind or level of employee benefits (other than Base Salary) to which Executive is entitled immediately prior to such reduction with the result that
Executive’s overall benefits package (other than Base Salary) is substantially reduced (other than any such reduction applicable to officers of the Company generally), (4) any material breach by the Company of any material provision of
this Agreement which continues uncured for thirty (30) days following notice by Executive thereof, or (5) a refusal by Executive, following a request by the Company, to relocate to a facility or location more than forty (40) miles
from the Company’s current location, and (B) Executive provides notice to the Company within thirty (30) days after the initial occurrence of the condition or event described above, the Company fails to cure or remedy any such
condition or event within the thirty (30) day period following its receipt of the notice, and Executive thereafter elects to terminate his employment voluntarily within thirty (30) days after the expiration of the period for correcting
such condition or event; provided, however, that none of the foregoing shall constitute Good Reason to the extent that Executive has agreed in writing to such material change, reduction, breach or refusal, and provided further that any
change in Executive’s job function or responsibilities in order to accommodate a disability under the Americans with Disabilities Act, the Family Medical Leave Act or any analogous statute or law shall not constitute a basis for Executive to
involuntarily terminate his employment hereunder. 
 (d) Involuntary Termination. For purposes of this Agreement, an
“Involuntary Termination” shall be deemed to occur if: (i) Executive’s employment with the Company is terminated by the Company for any reason other than Cause (and for a reason other than Executive’s death or
Disability); or (ii) Executive terminates his employment with the Company for Good Reason. 
 7. Proprietary Information and
Inventions Agreement. Executive acknowledges that he is and will continue to be bound by the terms and conditions of the Proprietary Information and Inventions Agreement (the “PIIA”), a copy of which is attached hereto as
Exhibit A, provided that if the provisions of this Agreement and the provisions of the PIIA conflict or are inconsistent, the provisions of this Agreement shall govern. 

  
 -4- 

 8. Conditional Nature of Severance Payments. 

(a) Non-Solicitation; Non-Competition. Executive agrees and acknowledges that Executive’s right to receive the severance benefits
set forth in Section 5 (to the extent Executive is otherwise entitled to such benefits) shall be conditioned upon Executive’s continued compliance with Section 8 (Non-Solicitation) and Section 9 (Non-Competition) of the PIIA and
Section 8(b) of this Agreement. Upon any breach of this section, all severance benefits pursuant to this Agreement shall immediately cease including, without limitation, Executive’s right to exercise any stock options on a date that is
more than ninety (90) days after the date that Executive’s employment was terminated. 
 (b) Non-Disparagement. During and
after the Employment Term, Executive agrees to refrain from any defamation, libel or slander of the Company and its officers, directors, employees, agents, investors, stockholders, administrators, affiliates, divisions, subsidiaries, predecessor and
successor corporations, and assigns, and any tortious interference with the contracts, relationships and prospective economic advantage of any of the foregoing persons and entities. 

(c) Understanding of Covenants. Executive represents that he (i) is familiar with the covenants set forth in Section 8 and
Section 9 of the PIIA, and (ii) is fully aware of his obligations hereunder, including, without limitation, the reasonableness of the length of time, scope and geographic coverage of such covenants. 

9. Confidentiality of Terms. Executive agrees to follow the Company’s strict policy that employees must not disclose, either
directly or indirectly, any of the terms of this Agreement to any person, including other employees of the Company; provided, however, that Executive may discuss such terms with members of Executive’s immediate family and any
legal, tax or accounting specialists who provide Executive with individual legal, tax or accounting advice. 
 10. Assignment. This
Agreement will be binding upon and inure to the benefit of (a) the heirs, executors and legal representatives of Executive upon Executive’s death and (b) any successor of the Company. Any such successor of the Company will be deemed
substituted for the Company under the terms of this Agreement for all purposes. For this purpose, “successor” means any person, firm, corporation or other business entity which at any time, whether by purchase, merger or otherwise,
directly or indirectly acquires all or substantially all of the assets or business of the Company. None of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will
or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance or other disposition of Executive’s right to compensation or other benefits will be null and void. 

11. Notices. All notices, requests, demands and other communications called for hereunder shall be in writing and shall be deemed given
(a) on the date of delivery if delivered personally, (b) one (1) day after being sent by a well established commercial overnight service, or (c) four (4) days after being mailed by registered or certified mail, return

and addressed to the parties or their successors at the following addresses, or at such other addresses as the parties may later designate in writing: 

If to the Company: 
 NanoString
Technologies, Inc. 
 530 Fairview Ave. N., Suite 2000 

Seattle, WA 98109 
 Attn: CEO 

If to Executive: 
 to the last
residential address known by the Company. 
 12. Severability. In the event that any provision hereof becomes or is declared by a
court of competent jurisdiction to be illegal, unenforceable or void, this Agreement will continue in full force and effect without said provision. 

13. Application of Section 409A. Notwithstanding anything to the contrary set forth herein, any payments and benefits provided
under this Agreement that constitute “deferred compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations and other guidance thereunder and any
state law of similar effect (collectively, the “Section 409A”) shall not commence in connection with Executive’s termination of employment unless and until Executive has also incurred a “separation from service” (as
such term is defined in Treasury Regulation Section 1.409A-1(h) (the “Separation From Service”), unless the Company reasonably determines that such amounts may be provided to Executive without causing Executive to incur the
additional 20% tax under Section 409A. 
 It is intended that each installment of severance pay provided for in this Agreement is a
separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). For the avoidance of doubt, it is intended that severance payments set forth in this Agreement satisfy, to the greatest extent possible, the exceptions
from the application of Section 409A provided under Treasury Regulation Sections 1.409A-1(b)(4) and 1.409A-1(b)(9). 
 If the Company
(or, if applicable, the successor entity thereto) determines that any payments or benefits constitute “deferred compensation” under Section 409A and Executive is, on the termination of service, a “specified employee” of the
Company or any successor entity thereto, as such term is defined in Section 409A(a)(2)(B)(i) of the Code, then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing
of the payments and benefits shall be delayed until the earlier to occur of: (a) the date that is six months and one day after Executive’s Separation From Service, or (b) the date of Executive’s death (such applicable date, the
“Specified Employee Initial Payment Date”). On the Specified Employee Initial Payment Date, the Company (or the successor entity thereto, as applicable) shall (i) pay to Executive a lump sum amount equal to the sum of the
payments and benefits that Executive would otherwise have received through the Specified Employee Initial Payment Date if the commencement of the payment of such amounts had not been so delayed pursuant to this Section and (ii) commence paying
the balance of the payments and benefits in accordance with the applicable payment schedules set forth in this Agreement. 
 14.
Arbitration. 
 (a) General. In consideration of Executive’s service to the Company, his promise to arbitrate all
employment related disputes and Executive’s receipt of the compensation, 

  
 -6- 

 
pay raises and other benefits paid to Executive by the Company, at present and in the future, Executive agrees that any and all controversies, claims, or disputes with anyone (including the
Company and any employee, officer, director, stockholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s service to the Company under this Agreement or otherwise
or the termination of Executive’s service with the Company, including any breach of this Agreement, shall be subject to binding arbitration under the Arbitration Rules set forth in the Revised Code of Washington Chapter 7.04 (the
“Rules”) and pursuant to Washington law. Disputes which Executive agrees to arbitrate, and thereby agrees 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, claims of harassment, discrimination or wrongful
termination. Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive. 

(b) Procedure. Executive agrees 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. The arbitration proceedings will allow for discovery according to the National Rules
for the Resolution of Employment Disputes and the Washington Code of Civil Procedure. Executive agrees 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. Executive agrees that the arbitrator shall issue a written decision on the merits with findings of fact and conclusions of law. Executive also agrees that
the arbitrator shall have the power to award any remedies, including attorneys’ fees and costs, available under applicable law. Executive understands the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA
except that Executive shall pay the first $200.00 of any filing fees associated with any arbitration Executive initiates. Executive agrees that the arbitrator shall administer and conduct any arbitration in a manner consistent with the Rules and
that to the extent that the AAA’s National Rules for the Resolution of Employment Disputes conflict with the Rules, the Rules shall take precedence. 

(c) Remedy. Except as provided by the Rules, arbitration shall be the sole, exclusive and final remedy for any dispute between
Executive and the Company. Accordingly, except as provided for by the Rules, neither Executive nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, 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) Availability of Injunctive Relief. In addition to the right under the Rules to petition the court for provisional relief, Executive
agrees that any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the PIIA or any other agreement regarding trade secrets, confidential information, non-competition,
non-solicitation or non-disparagement. In the event either party seeks injunctive relief, the prevailing party shall be entitled to recover reasonable costs and attorneys’ fees. 

  
 -7- 

 Administrative Relief. Executive understands that this Agreement does not prohibit
Executive from pursuing an administrative claim with a local, state or federal administrative body such as the Washington State Human Rights Commission, Equal Employment Opportunity Commission or the workers’ compensation board. This Agreement
does, however, preclude Executive from pursuing court action regarding any such claim. 
 15. Legal Fees and Expenses. 

(a) Unless prohibited by law, if Employee prevails on at least one substantive issue in seeking to enforce the Company’s obligations under
this Agreement, the Company shall pay and be solely responsible for any and all costs and expenses (including attorneys’ fees) incurred by Employee in connection with Employee’s action to enforce the Company’s obligations under this
Agreement. The Company shall pay directly or reimburse Employee for any and all such costs and expenses within sixty (60) calendar days following the presentation by Employee or by counsel selected from time to time by Employee of a statement
or statements prepared by Employee or by such counsel of the amount of such costs and expenses. The Company shall also pay to Employee interest (calculated at the prime rate from time to time in effect at Bank of America, compounded monthly) on any
payments or benefits that are paid or provided to Employee later than the date on which due under the terms of this Agreement. 
 (b) In
order to comply with Section 409A of the Code, (a) in no event will the payments by the Company under Section 15 of this Agreement be made later than the end of the calendar year next following the calendar year in which such fees and
expenses were incurred; Employee shall be required to submit an invoice for such fees and expenses at least 10 days before the end of the calendar year next following the calendar year in which such fees and expenses were incurred; (b) the
amount of such legal fees and expenses that the Company is obligated to pay in any given calendar year will not affect the legal fees and expenses that the Company is obligated to pay in any other calendar year; (c) the Company’s
obligation to pay Employee’s legal fees will terminate on the fifth anniversary of the termination of this Agreement; and (d) Employee’s right to have the Company pay such legal fees and expenses may not be liquidated or exchanged for
any other benefit. 
 (c) Any amount paid to Employee for the reimbursement of legal fees and expenses under this section shall not exceed
$50,000 prior to a Change of Control and $100,000 after a Change of Control. 
 16. Voluntary Nature of Agreement. Executive
acknowledges and agrees that Executive is executing this Agreement voluntarily and without any duress or undue influence by the Company or any other person. Executive further acknowledges and agrees that Executive has carefully read this Agreement
and that Executive has asked any questions needed for Executive to understand the terms, consequences and binding effect of this Agreement and fully understand it, including that Executive is waiving Executive’s right to a jury trial. Finally,
Executive agrees that Executive has been provided an opportunity to seek the advice of an attorney of Executive’s choice before signing this Agreement. 

  
 -8- 

 17. Integration. This Agreement, any stock option and restricted stock agreements between
the Company and Executive and the PIIA represent the entire agreement and understanding between the parties as to the subject matter herein and supersede all prior or contemporaneous agreements whether written or oral. No waiver, alteration, or
modification of any of the provisions of this Agreement will be binding unless in writing and signed by duly authorized representatives of the parties hereto. 

18. Tax Withholding. All payments made pursuant to this Agreement will be subject to withholding of applicable taxes. 

19. Governing Law. This Agreement will be governed by the laws of the State of Washington, without giving effect to principles of
conflict of laws. 
 IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first above written.

(b) I attach hereto as Exhibit A a complete list of all Inventions, if any, made by me prior to my employment or consulting
relationship with the Company that are relevant to the Company’s business, and I represent and warrant that such list is complete. If no such list is attached to this Agreement, I represent that I have no such Inventions at the time of signing
this Agreement. If in the course of my employment or consultancy (as the case may be) with the Company, I use or incorporate into a product or process an Invention not covered by Section 4(a) of this Agreement in which I have an interest, the
Company is hereby granted a nonexclusive, fully paid-up, royalty-free, perpetual, worldwide license of my interest to use and sublicense such Invention without restriction of any kind. 

NOTICE REQUIRED BY REVISED CODE OF WASHINGTON 49.44.140: 

Any assignment of Inventions required by this Agreement does not apply to an Invention for which no equipment, supplies, facility or trade
secret information of the Company was used and which was developed entirely on the employee’s own time, unless (a) the Invention relates (i) directly to the business of the Company or (ii) to the Company’s actual or
demonstrably anticipated research or development or (b) the Invention results from any work performed by the employee for the Company. 

5. Further Assistance; Power of Attorney. I agree to perform, during and after my employment or consulting relationship,
all acts deemed necessary or desirable by the Company to permit and assist it, at its expense, in obtaining and enforcing the full benefits, enjoyment, rights and title throughout the world in the Inventions assigned to the Company as set forth in
Section 4 above. Such acts may include, but are not limited to, execution of documents and assistance or cooperation in legal proceedings. I hereby irrevocably designate the Company and its duly authorized officers and agents as my agent and
attorney-in fact, to execute and file on my behalf any such applications and to do all other lawful acts to further the prosecution and issuance of patents, copyright and mask work registrations related to such Inventions. This power of attorney
shall not be affected by my subsequent incapacity. 
 6. Inventions. As used in this Agreement, the term

consulting relationship with the Company, and for a period of one year following the termination of my relationship with the Company for any reason, I will not directly or indirectly solicit, induce, recruit or encourage any of the Company’s
employees or consultants to terminate their relationship with the Company, or attempt any of the foregoing, either for myself or any other person or entity. Further, at any time following termination of my relationship with the Company for any
reason, I shall not use any Proprietary Information of the Company to attempt to negatively influence any of the Company’s clients or customers from purchasing any of the Company’s products or services, or solicit any licensor to or
customer of the Company or licensee of the Company’s products, that are known to me, with respect to any business, products or services that are competitive to the products or services offered by the Company or under development as of the date
of termination of my relationship with the Company.

relationship with the Company and for one year following the termination of my relationship with the Company for any reason, I will not, without the Company’s prior written consent, directly or indirectly work on any products or services that
are competitive with products or services (a) being commercially developed or exploited by the Company during my employment or consultancy and (b) on which I worked or about which I learned Proprietary Information during my employment or
consultancy with the Company. 
 10. No Conflicts. I represent that my performance of all the terms of this Agreement as an
employee of or consultant to the Company does not and will not breach any agreement to keep in confidence proprietary information, knowledge or data acquired by me in confidence or in trust prior to my becoming an employee or consultant of the

obligation or liability. 
 14. Injunctive Relief. I acknowledge that violation of this Agreement by me may cause irreparable
injury to the Company, and I agree that the Company will be entitled to seek extraordinary relief

This Agreement shall be governed by the laws of the State of Washington applicable to contracts entered into and performed entirely within the State of Washington, without giving effect to principles of conflict of laws. If any provision of this
