NATIONAL INSTRUMENTS CORPORATION
EXECUTIVE EMPLOYMENT AGREEMENT

This Employment Agreement (this “Agreement”) is entered into by and between Eric
Starkloff (“Executive”) and National Instruments Corporation (“Company”) is
entered into as of October 28, 2019, and will become effective on February 1,
2020 (the “Effective Date”).
1.Duties and Scope of Employment.
(a)    Positions and Duties. As of the Effective Date, Executive will transition
out of his current role with the Company and into the position of its President
and Chief Executive Officer, based in the Company’s Austin, Texas headquarters.
Executive will report to the Company’s Board of Directors (the “Board”). As of
the Effective Date, 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 Board). The
period of Executive’s employment under this Agreement is referred to herein as
the “Employment Period.”
(b)    Board Membership. Upon commencement of the Employment Period (or as soon
as practicable thereafter), the Board shall appoint Executive to the Board as a
director, subject to any required Board approval, and Executive shall continue
to serve as a director during the Employment Period subject to any required
approvals from the Company’s Board, Nominating and Governance Committee, and
stockholders.
(c)    Obligations. During the Employment Period, Executive will perform his
duties faithfully and to the best of his ability and will devote his full
business efforts and time to the Company. For the duration of the Employment
Period, Executive agrees not to engage in any other employment, occupation, or
consulting activity for any direct or indirect remuneration without the Board’s
prior written approval.
2.    At-Will Employment. The Parties agree that Executive’s employment with the
Company will continue to be at-will employment and therefore may be terminated
at any time with or without cause or notice, for any reason or no reason.
However, as described in this Agreement, Executive may be entitled to severance
benefits depending on the circumstances of Executive’s termination of employment
with the Company. The Company requests that, in the event of Executive’s
resignation, where practicable, he provide the Company with up to ninety (90)
days’ advance notice. The Company may, in its discretion, accelerate the
separation date during that period without altering the nature of Executive’s
resignation. Any such requested notice period does not alter the at-will nature
of Executive’s employment with the Company.
3.    Compensation.
(a)    Base Salary. As of the Effective Date, Executive’s annual base salary
will increase to a rate of $700,000 per annum (the “Base Salary”), payable in
accordance with the Company’s normal payroll practices and subject to usual
required withholdings. The first and last payment of Executive’s Base Salary
will be adjusted, if necessary, to reflect a commencement or termination date
other than the first or last working day of a pay period.

-1-

--------------------------------------------------------------------------------

(b)    Annual Bonus. As of the Effective Date, Executive will remain eligible to
participate in the Company Annual Incentive Program (“AIP”) with an annual
target of 110% of Base Salary, with performance goals commensurate with
Executive’s position, as specified by the Board or the Compensation Committee of
the Board (the “Committee”), as may be applicable. The actual earned AIP bonus
will be determined based on achievement of performance goals and paid no later
than two and one-half (2-1/2) months following the end of the performance year.
Executive will also continue to be eligible to participate in the Company’s
Annual Cash Performance Bonus Program, in accordance with the terms of the
program as in effect from time to time.
(c)    Restricted Stock Unit Award. Subject to the approval of the Board, on
February 1, 2020, Executive will be granted 150,000 restricted stock units under
the Company’s equity incentive plan (the “Initial Award”). One-half of the
restricted stock units subject to the Initial Award will be scheduled to vest
annually over three (3) years subject to Executive’s continued service as an
employee through each vesting date. The remaining restricted stock units subject
to the Initial Award will vest based on the Company’s total shareholder return
performance in relation to the performance of the Russell 2000 index over a
three-year period commencing January 1, 2020 and subject further to Executive’s
continued employment through the vesting date. In addition, at the Company’s
next equity award approval cycle, expected in April 2020, Executive will be
granted additional restricted stock units under the Company’s equity incentive
plan equal to the result (rounded to the nearest whole share) of $2,000,000
divided by the Company’s common stock closing price on the day immediately
preceding the grant date (“Supplemental Award”). The Supplemental Award will be
subject to approval of the Board and will be scheduled to vest as to one-half of
the restricted stock units annually over a three-year period subject to
Executive’s continued service as an employee through each vesting date. The
remaining restricted stock units subject to the Supplemental Award will be
scheduled to vest based on the Company total shareholder return performance
relative to the Russell 2000 index over a three-year performance period
commencing January 1, 2020 and subject further to Executive’s continued
employment through the vesting date. Both the Initial Award and the Supplemental
Award will be subject to the terms of the Company’s 2015 Equity Incentive Plan
or a successor plan, as applicable, and to the standard approved form of
service-based and performance-based restricted stock unit agreement thereunder
(the “Equity Award Documents”) and to Executive’s continued employment through
the award grant date. Executive understands and agrees that, to the extent he
becomes eligible for any future equity grants, such grant would be subject to
any required Board approval and subject to the relevant equity documents as then
in effect at the Company.
4.    Employee Benefits. During the Employment Period, Executive and Executive’s
eligible dependents will continue to be eligible to participate in Company
employee benefit plans and perquisites and fringe benefit programs, including
medical, dental, 401(k), company performance bonus and stock purchase plan, made
available to other senior executive-level employees, as in effect from time to
time.
5.    Vacation. During the Employment Period, Executive will be entitled to paid
vacation in accordance with the Company’s then-current policy for other
executive-level employees.
6.    Severance Benefits.
(a)    Termination Without Cause or Resignation for Good Reason. If the Company
terminates Executive’s employment involuntarily without Cause (excluding any
termination due to death or Disability) or Executive resigns for Good Reason,
then, subject to the limitations of Sections 7 and 8 below, Executive shall be
entitled to receive: (i) continuing severance pay at a rate equal to one-hundred
percent (100%) of the Executive’s Base Salary, as then in effect (less
applicable withholding), for a period of eighteen (18) months from the date of
such termination, paid in accordance with the Company’s normal payroll
practices; (ii) to the extent not already earned and accrued, a lump sum
equivalent to one hundred percent (100%) of Executive’s AIP bonus as in effect
at the time of the applicable termination or resignation, less applicable
withholding, which amount shall be paid at such time annual bonuses are paid to
other senior executives of the Company (for avoidance of doubt in no case would
Executive be entitled to more than one AIP bonus payment under the terms of this
provision); (iii) accelerated vesting of Executive’s outstanding Company
service-based restricted stock units that would have vested had

-2-

--------------------------------------------------------------------------------

Executive remained employed by the Company for twelve (12) months following the
termination date, and subject to any required approval by the Board; and (iv)
provided Executive timely elects healthcare continuation coverage under the
Consolidated Omnibus Budget Reconciliation Act of 1986 (“COBRA”), Company
reimbursement of Executive for, or direct payment of, Executive’s COBRA premiums
(at the coverage level in effect immediately prior to Executive’s termination)
until the earlier of eighteen (18) months following the termination date or the
date Executive becomes covered under similar plans. If the Company determines,
in its sole discretion, that it cannot provide the foregoing benefit related to
COBRA premiums without potentially violating, or being subject to an excise tax
under, applicable law, the Company will instead provide a taxable monthly
payment of an equivalent amount, which will be made regardless of whether
Executive elects COBRA and continue until the earlier of eighteen (18) months
following termination or the date Executive becomes covered under similar plans.
(b)    Change in Control Benefits. Notwithstanding any contrary provision in the
preceding paragraph, if a termination described in Section 6(a) occurs within
the period beginning three months prior to a Change in Control and ending twelve
(12) months following a Change in Control, then the Executive will be entitled
to receive the same severance in Section 6(a) except the severance amount in
Section 6(a)(i) will be paid in a lump-sum on the sixtieth (60th) day following
the termination date. For avoidance of doubt, Executive’s equity awards will
remain subject to the Change in Control vesting or other treatment as provided
for under the terms of the Company’s equity plan and Executive’s equity award
agreements, as applicable, notwithstanding Executive’s eligibility to receive
vesting acceleration under Section 6(a)(iii) of this Agreement in the event of a
termination described in Section 6(a).
(c)    Voluntary Resignation; Termination for Cause. If Executive’s employment
with the Company or its Affiliates terminates (i) voluntarily by Executive
(other than for Good Reason) or (ii) for Cause by the Company, then Executive
will not be entitled to receive severance or other benefits except for those (if
any) as may then be established under the Company’s then existing severance and
benefits plans and practices or pursuant to other written agreements with the
Company, if applicable.
(d)    Disability; Death. If the Company terminates Executive’s employment as a
result of Executive’s Disability, or Executive’s employment terminates due to
Executive’s death, then Executive will not be entitled to receive severance or
other benefits except for those (if any) as may then be established under the
Company’s then existing written severance and benefits plans and practices or
pursuant to other written agreements with the Company, if applicable.
(e)    Accrued Compensation. For the avoidance of any doubt, in the event of a
termination of Executive’s employment with the Company or its Affiliates,
Executive will be entitled to receive all accrued but unpaid base salary, any
earned but unused vacation pay and reimbursement for any unreimbursed expenses,
in accordance with Company policies then in effect and applicable law.
(f)    Transfer between the Company and Affiliates. For purposes of this
Section 6, Executive will not be determined to have been terminated without
Cause, where Executive continues to remain employed by the Company or one of its
Affiliates (e.g., upon transfer from on Affiliate to another); provided,
however, that the parties understand and acknowledge that any such transfer
could potentially result in Executive’s ability to resign for Good Reason.
(g)    Exclusive Remedy. Severance benefits provided to the Executive pursuant
to this Section 6 are in lieu of, and not in addition to, any benefits to which
Executive may otherwise be entitled under any Company severance plan, policy or
program.
7.    Conditions to Receipt of Severance. Any severance payments, equity
acceleration, or other payments or benefits under Section 6(a) and (b) above are
conditioned on Executive’s continued compliance with the Proprietary Rights
Agreement (defined below), including the restrictive covenants therein, and on
Executive’s

-3-

--------------------------------------------------------------------------------

signing and not revoking separation agreement and release, including a general
release of claims against the Company and certain related persons and entities,
in a form reasonably satisfactory to the Company (the “Release”) and such
Release becoming effective in accordance with its terms (such date, the “Release
Effective Date”) within sixty (60) days following your termination date (the
“Release Deadline”). Severance payments or benefits shall be paid or commence,
as applicable, upon the first payroll date following the Release Effective Date
and such payment will include the amount of any installment that would otherwise
been paid prior to such payment date. All other benefits, if any, due to
Executive following a termination will be determined in accordance with the
plans, policies and practices of the Company as then in effect. Notwithstanding
the foregoing, to the extent required to comply with Section 409A of the
Internal Revenue Code and the regulations and guidance promulgated thereunder
(“Section 409A”), if the sixty (60) day Release period spans two (2) calendar
years, the severance payments will be delayed to the first scheduled payroll
date in the second year (and will include all payments that would otherwise have
been made prior to such date). Severance payments will not be paid or provided
until the Release becomes effective and irrevocable.
8.    Section 409A. The parties intend that this Agreement be interpreted to
comply with or be exempt from Section 409A so that none of the severance
payments or benefits provided hereunder will be subject to the additional tax
imposed under Section 409A. For purposes of determining severance, a termination
of employment shall mean not be deemed to have occurred unless the termination
is also a “separation from service” within the meaning of Section 409A. If
Executive is a “specified employee” within the meaning of Section 409A, then the
severance and any other separation benefits payable upon a separation from
service (whether under this Agreement or otherwise) that would constitute
deferred compensation under Section 409A (the “Deferred Payments”), otherwise
due to Executive on or within the six (6)-month period following Executive’s
separation from service will accrue during such six (6)-month period and will
become payable in a lump sum payment on the date six (6) months and one (1) day
following the date of Executive’s separation from service (such rule, the “Six
Month Delay Rule”) or, if earlier, the date of your death. All subsequent
Deferred Payments following the application of the Six Month Delay Rule, if any,
will be payable in accordance with the payment schedule applicable to each
payment or benefit or, if earlier, upon the date of Executive’s death. Each
payment and benefit payable under this Agreement is intended to constitute a
separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury
Regulations. Executive and the Company agree to work together in good faith to
consider amendments to this Agreement and to take such reasonable actions that
are necessary, appropriate or desirable to avoid subjecting Executive to an
additional tax or income recognition under Section 409A prior to actual payment
of any payments and benefits under this Agreement, as applicable. In no event
will the Company reimburse Executive for any taxes that may be imposed on
Executive as a result of Section 409A.
9.Limitation on Payments. In the event that the severance and other benefits
provided for in this Agreement or otherwise payable to Executive (i) constitute
“parachute payments” within the meaning of Section 280G of the Code and (ii) but
for this Section 9, would be subject to the excise tax imposed by Section 4999
of the Code, then Executive’s severance benefits under Section 6 will be either:
(a)    delivered in full, or
(b)    delivered as to such lesser extent which would result in no portion of
such severance benefits being subject to excise tax under Section 4999 of the
Code, whichever of the foregoing amounts, taking into account the applicable
federal, state and local income taxes and the excise tax imposed by Section 4999
of the Code, results in the receipt by Executive on an after-tax basis, of the
greatest amount of severance benefits, notwithstanding that all or some portion
of such severance benefits may be taxable under Section 4999 of the Code. If a
reduction in severance and other benefits constituting “parachute payments” is
necessary so that benefits are delivered to a lesser extent, reduction will
occur in the following order: (i) reduction of cash payments; (ii) cancellation
of awards granted “contingent on a change in ownership or control” (within the
meaning of Code Section 280G); (iii) cancellation of accelerated vesting of
equity awards; or (iv) reduction of employee benefits. In the event that
acceleration of vesting of equity award compensation is to be reduced, such
acceleration of vesting will be cancelled

-4-

--------------------------------------------------------------------------------

in the reverse order of the date of grant of Executive’s equity awards. Unless
the Company and Executive otherwise agree in writing, any determination required
under this Section 9 will be made in writing by a nationally recognized
accounting or valuation firm (the “Firm”) selected by the Company, whose
determination will be conclusive and binding upon Executive and the Company for
all purposes. For purposes of making the calculations required by this
Section 9, the Firm may make reasonable assumptions and approximations
concerning applicable taxes and may rely on reasonable, good faith
interpretations concerning the application of Sections 280G and 4999 of the
Code. The Company and Executive will furnish to the Firm such information and
documents as the Accountants may reasonably request in order to make a
determination under this Section. The Company will bear all costs the Firm may
reasonably incur in connection with any calculations contemplated by this
Section 9.
10.Definitions. The following terms referred to in this Agreement will have the
following meanings:
(a)    Affiliate. “Affiliate” means Company and any other parent or subsidiary
corporations of the Company, as such terms are defined in Section 424(e) of the
Code.
(b)    Cause. “Cause” means the occurrence of one or more of the following: (i)
Executive’s indictment for the commission of any felony or a misdemeanor
involving deceit, material dishonesty or fraud, or any other such conduct by
Executive that would reasonably be expected to result in material injury or
reputational harm to the Company if Executive were retained in his position;
(ii) Executive’s material violation of this Agreement, the Proprietary Rights
Agreement, or any other material agreement with the Company, including any
misappropriation or disclosure of confidential and proprietary information or
trade secrets of the Company and its subsidiaries or affiliates; (iii) continued
failure to substantially perform Executive’s duties with the Company (other than
any such failure resulting from Executive’s Disability) after a written demand
for substantial performance is delivered to Executive by the Board, which is not
substantially corrected by Executive to the satisfaction of the Board within
thirty (30) days of receipt of such demand; (iv) a breach by Executive of
Executive’s fiduciary duties and responsibilities to the Company that would be
reasonable likely to result in a material injury or effect on the Company’s
business, operations, prospects or reputation; (v)  Executive’s participation in
releasing financial statements known by Executive to be false or materially
misleading or intentional submission of a false certification to the Securities
and Exchange Commission or other governmental agency or authority;  (vi) a
material violation of the Company’s Code of Ethics or other policies of the
Company, as determined by the Board its sole discretion; or (vii)  failure to
cooperate with a bona fide internal investigation or an investigation by
regulatory or law enforcement authorities, after being instructed by the Board
to cooperate, or the destruction or failure to preserve documents or other
materials known to be relevant to such investigation or the inducement of others
to fail to cooperate or to produce documents or other materials in connection
with such investigation.
(c)    Change in Control. “Change in Control” means (i) Any “person” (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act) becomes
the “beneficial owner” (as defined in Rule 13d-3 of the Exchange Act), directly
or indirectly, of securities of the Company representing fifty percent (50%) or
more of the total voting power represented by the Company’s then outstanding
voting securities; (ii) the consummation of the sale or disposition by the
Company of all or substantially all of the Company’s assets; (iii) a change in
the effective control of the Company which occurs on the date that a majority of
the members of the Board is replaced during any twelve (12) month period by
directors whose appointment or election is not endorsed by a majority of the
members of the Board prior to the date of the appointment or election; or (iv)
the consummation of a merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity or its parent) at least fifty
percent (50%) of the total voting power represented by the voting securities of
the Company or such surviving entity or its parent outstanding immediately after
such merger or consolidation. Notwithstanding the foregoing definition, any
payment or benefit that would be considered deferred compensation subject to,
and not exempt from, Section 409A, payable or to be provided upon a Change in
Control shall only be paid or provided to Executive to the extent such event
also qualifies as an event described in Internal Revenue Code Section
409A(a)(2)(A)(v).

-5-

--------------------------------------------------------------------------------

(d)    Disability. “Disability” means Executive’s entitlement to benefits under
Company’s long-term disability plan or if Executive does not participate in
Company’s long term-disability plan, Executive’s inability, due to physical or

a period of ninety (90) consecutive days or one-hundred twenty (120) days during
any consecutive six-month period.
(e)    Good Reason. “Good Reason” means Executive’s resignation within thirty
(30) days following the expiration of any Company cure period (discussed below)
following the occurrence of one or more of the following, without Executive’s
written consent: (i) a material diminution of Executive’s authority, duties or
responsibilities relative to Executive’s authority, duties or responsibilities
in effect immediately prior to such diminution; provided, however, that a
reduction in the Executive’s authority, duties or responsibilities solely by
virtue of the Company being acquired and made part of a larger entity (for
example, “Good Reason” does not exist if the Executive is employed by the
Company with substantially the same responsibilities with respect to the
Company’s business that Executive had immediately prior to the Change of Control
regardless of whether Executive’s title is revised to reflect Executive’s
placement within the overall corporate hierarchy or whether Executive provides
services to a subsidiary, affiliate, business unit or otherwise); (ii) a
material reduction by the Company in the base compensation or target bonus of
the Executive as in effect immediately prior to such reduction, other than a
reduction of up to 25% that is also applied to other senior executives of the
Company; or (iii) the relocation of Executive to a facility or a location more
than one hundred (100) miles from Executive’s then-present location. Executive’s
resignation will not be deemed to be for Good Reason unless Executive has first
provided the Company with written notice of the acts or omissions constituting
the grounds for “Good Reason” within ninety (90) days of the initial existence
of the grounds for “Good Reason” and a reasonable cure period of not less than
thirty (30) days following the date the Company receives such notice, and such
condition has not been cured during such period.
11.Company Matters.
(a)    Proprietary Information and Inventions. Executive acknowledges and agrees
that as a condition of his continued employment with the Company under this
Agreement, he will be required to sign and comply with an At-Will Employment,
Confidential Information, Invention Assignment, and Arbitration Agreement (the
“Proprietary Rights Agreement”), a copy of which is attached hereto as Exhibit
A. Executive further acknowledges and agrees that he will continue to abide by
the Company Values and Guidelines and the Company Code of Ethics, which remain
in full force and effect, as well as other Company policies as in effect from
time to time. In the event of any conflict between any pre-existing
confidentiality, non-compete, or non-disclosure obligations and the terms of the
restrictive covenants agreement set forth in the Proprietary Rights Agreement,
the terms of the Proprietary Rights Agreement shall control.
(b)     Resignation on Termination. On termination of his employment, regardless
of the reason thereof, Executive shall immediately (and with contemporaneous
effect) resign any directorships, offices, or other positions he may hold in the
Company unless otherwise agreed in writing by the Parties.
(c)    Notification of New Employer. In the event that Executive leaves the
employ of the Company, Executive grants consent to notification by the Company
to Executive’s new employer about his rights and obligations under this
Agreement and the Proprietary Rights Agreement.
12.Arbitration. IN CONSIDERATION OF EXECUTIVE’S CONTINUED EMPLOYMENT WITH THE
COMPANY, ITS PROMISE TO ARBITRATE ALL EMPLOYMENT-RELATED DISPUTES AND
EXECUTIVE’S RECEIPT OF THE COMPENSATION, PAY RAISES AND OTHER BENEFITS PAID TO

ANY AND ALL CONTROVERSIES, CLAIMS, OR DISPUTES WITH ANYONE (INCLUDING THE
COMPANY AND ANY EMPLOYEE, OFFICER, DIRECTOR, SHAREHOLDER OR BENEFIT PLAN, IN
THEIR CAPACITY AS SUCH OR OTHERWISE) ARISING OUT OF, RELATING TO, OR RESULTING
FROM

-6-

PROPRIETARY RIGHTS AGREEMENT, AND SUBJECT TO THE PROVISIONS THEREIN REGARDING
PROTECTED ACTIVITY.
13.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.

under this Agreement shall be in writing and shall be delivered personally by
hand or by courier, mailed by United States first-class mail, postage prepaid,
or sent by email directed to the party to be notified at the physical address or

(10) days’ advance written notice to the other Parties hereto. All such notices
and other communications shall be deemed given upon personal delivery, three (3)
days after the date of mailing, or upon sending the email.
15.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.
16.Integration. This Agreement, together with the Proprietary Rights Agreement,
any other agreements relating to proprietary rights between you and the Company,
the Equity Award Agreements, the Indemnification Agreement, dated March 6, 2014,
and the Company’s Employee Handbook and Code of Ethics, set forth the terms of
your employment with the Company as of the Effective Date and supersede any
prior representations and agreements, whether written or oral. This Agreement
supersedes any prior employment agreement between you and the Company,
including, but not limited, to the letter agreement entered into in connection
with your promotion to President and Chief Operating Officer dated October 23,
2018.
17.Tax Withholding. All payments made pursuant to this Agreement will be subject
to withholding of applicable taxes.
18.Waiver. No party to this Agreement shall be deemed to have waived any right,
power or privilege under this Agreement or any provisions hereof unless such
waiver shall have been duly executed in writing and acknowledged by the party to
be charged with such waiver. No waiver of any breach of this Agreement shall be
held to be a waiver of any other subsequent breach.

Texas (with the exception of its conflicts of law provisions). Subject to the

EXECUTIVE EMPLOYMENT AGREEMENT

--------------------------------------------------------------------------------

Exhibit A

(Proprietary Rights Agreement)

NATIONAL INSTRUMENTS CORPORATION
AT-WILL EMPLOYMENT, CONFIDENTIAL INFORMATION,
INVENTION ASSIGNMENT, AND ARBITRATION AGREEMENT
As a condition of my employment with National Instruments Corporation (the
“Company”), and in consideration of my employment with the Company and my
receipt of the compensation now and hereafter paid to me by the Company, and
additional consideration of $100 paid to me by Company concurrently with the
execution of this Agreement, I agree to the following provisions of this At-Will
Employment, Confidential Information, Invention Assignment, and Arbitration
Agreement (this “Agreement”):
1.AT-WILL EMPLOYMENT
I UNDERSTAND AND ACKNOWLEDGE THAT MY EMPLOYMENT WITH THE COMPANY IS FOR NO
SPECIFIED TERM AND CONSTITUTES “AT-WILL” EMPLOYMENT. I ALSO UNDERSTAND THAT ANY
REPRESENTATION TO THE CONTRARY IS UNAUTHORIZED AND NOT VALID UNLESS IN WRITING
AND SIGNED BY THE CHAIRMAN OF THE BOARD OF DIRECTORS OF THE COMPANY.
ACCORDINGLY, I ACKNOWLEDGE THAT MY EMPLOYMENT RELATIONSHIP MAY BE TERMINATED AT
ANY TIME, WITH OR WITHOUT GOOD CAUSE OR FOR ANY OR NO CAUSE, AT MY OPTION OR AT
THE OPTION OF THE COMPANY, WITH OR WITHOUT NOTICE. I FURTHER ACKNOWLEDGE THAT
THE COMPANY MAY MODIFY JOB TITLES, SALARIES, AND BENEFITS FROM TIME TO TIME AS
IT DEEMS NECESSARY.
2.CONFIDENTIALITY
A.Definition of Company Confidential Information. I understand that “Company
Confidential Information” means information (including any and all combinations
of individual items of information) that the Company has or will develop,
acquire, create, compile, discover or own, that has value in or to the Company’s
business which is not generally known and which the Company wishes to maintain
as confidential. Company Confidential Information includes both information
disclosed by the Company to me, and information developed or learned by me
during the course of my employment with the Company. Company Confidential
Information also includes all information of which the unauthorized disclosure
could be detrimental to the interests of the Company, whether or not such
information is identified as Company Confidential Information. By way of
example, and without limitation, Company Confidential Information includes any
and all non-public information that relates to the actual or anticipated
business and/or products, research or development of the Company, or to the
Company’s 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, customers of the Company on which I called or
with which I may become acquainted during the term of my employment), software,
developments, inventions, discoveries, ideas, processes, formulas, technology,
designs, drawings, engineering, hardware configuration information, marketing,
finances, and other business information disclosed by the Company either
directly or indirectly in writing, orally or by drawings or inspection of
premises, parts, equipment, or other Company property. Notwithstanding the
foregoing, Company Confidential Information shall not include any such
information which I can establish (i) was publicly known or made generally
available prior to the time of disclosure by the Company to me; (ii) becomes
publicly known or made generally available after disclosure by the Company to me
through no wrongful action or omission by me; or (iii) is in my rightful
possession, without confidentiality obligations, at the time of disclosure by
the Company as shown by my then-contemporaneous written records; provided that
any combination of individual items of information shall not be deemed to be

individual items are within such exception, unless the combination as a whole is
within such exception. I understand that nothing in

Proprietary Rights Agreement - 1

--------------------------------------------------------------------------------

this Agreement is intended to limit employees’ rights to discuss the terms,
wages, and working conditions of their employment, as protected by applicable
law.
B.Nonuse and Nondisclosure. I agree that during and after my employment with the
Company, I will hold in the strictest confidence and take all reasonable
precautions to prevent any unauthorized use or disclosure of Company
Confidential Information. I will not (i) use Company Confidential Information
for any purpose whatsoever other than for the benefit of the Company in the
course of my employment, or (ii) disclose Company Confidential Information to
any third party without the prior written authorization of the President, CEO,
General Counsel or the Board of Directors of the Company (as applicable). Prior
to disclosure, when compelled by applicable law, I shall provide prior written
notice to the President, CEO, and General Counsel of the Company (as
applicable). I agree that I obtain no title to any Company Confidential
Information, and that the Company retains all Confidential Information as the
sole property of the Company. I understand that my unauthorized use or
disclosure of Company Confidential Information during my employment may lead to
disciplinary action, up to and including, immediate termination and legal action
by the Company. I understand that my obligations under this Section 2.B shall
continue after termination of my employment and also that nothing in this
Agreement prevents me from engaging in protected activity, as described in
Section 14 below.
C.Former Employer Confidential Information. I agree that during my employment
with the Company, I will not improperly use, disclose, or induce the Company to
use any proprietary information or trade secrets of any former employer or other
person or entity with which I have an obligation to keep such proprietary
information or trade secrets in confidence. I further agree that I will not
bring onto the Company’s premises or transfer onto the Company’s technology
systems any unpublished document, proprietary information, or trade secrets
belonging to any such third party unless disclosure to, and use by, the Company
has been consented to, in writing, by such third party and the Company.
D.Third Party Information. I recognize that the Company has received, and in the
future may receive, from third parties (for example, customers, suppliers,
licensors, licensees, partners, and collaborators) as well as its subsidiaries
and affiliates (“Associated Third Parties”), information which the Company is
required to maintain and treat as confidential or proprietary information of
such Associated Third Parties (“Associated Third Party Confidential
Information”), and I agree to use such Associated Third Party Confidential
Information only as directed by the Company and to not use or disclose such
Associated Third Party Confidential Information in a manner that would violate
the Company’s obligations to such Associated Third Parties. By way of example,
Associated Third Party Confidential Information may include the habits or
practices of Associated Third Parties, the technology of Associated Third
Parties, requirements of Associated Third Parties, and information related to
the business conducted between the Company and such Associated Third Parties. I
agree at all times during my employment with the Company and thereafter, that I
owe the Company and its Associated Third Parties a duty to hold all such
Associated Third Party Confidential Information in the strictest confidence, and
not to use it or to disclose it to any person, firm, corporation, or other third
party except as necessary in carrying out my work for the Company consistent
with the Company’s agreement with such Associated Third Parties. I further agree
to comply with any and all Company policies and guidelines that may be adopted
from time to time regarding Associated Third Parties and Associated Third Party
Confidential Information. I understand that my unauthorized use or disclosure of
Associated Third Party Confidential Information or violation of any Company
policies during my employment may lead to disciplinary action, up to and
including, immediate termination and legal action by the Company.
3.OWNERSHIP

right, title, and interest in and to any and all copyrightable material, notes,

as provided in Section 3.G below (collectively, “Inventions”), are the sole

to the Company of any Inventions, and to deliver and assign and hereby
irrevocably assign fully to the Company all of my right, title and interest in
and to Inventions. I agree that this assignment includes a present conveyance to
the Company of ownership of Inventions that are not yet in existence. I further
acknowledge that all original works of authorship that are made by me (solely or
jointly with others) within the scope of and during the period of my employment
with the Company and that 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
Inventions is within the Company’s sole discretion and for its sole benefit, and
that no royalty or other consideration will be due to me as a result of the
Company’s efforts to commercialize or market any such Inventions.
B.Pre-Existing Materials. I will inform the Company, in writing, before
incorporating any inventions, discoveries, ideas, original works of authorship,
developments, improvements, trade secrets and other proprietary information or
intellectual property rights owned by me or in which I have an interest prior

limitation, any inventions that qualify as an “Other Invention” as defined below
in Section 3.G, (“Prior Inventions”) into any Invention or otherwise utilizing
any Prior Invention in the course of my employment with the Company; and the
Company is hereby granted a nonexclusive, royalty-free, perpetual, irrevocable,
transferable worldwide license (with the right to grant and authorize
sublicenses) to make, have made, use, import, offer for sale, sell, reproduce,
distribute, modify, adapt, prepare derivative works of, display, perform, and
otherwise exploit such incorporated or utilized Prior Inventions, without
restriction, including, without limitation, as part of, or in connection with,
such Invention, and to practice any method related thereto. I will not
incorporate any inventions, discoveries, ideas, original works of authorship,
developments, improvements, trade secrets and other proprietary information or
intellectual property rights owned by any third party into any Invention without
the Company’s prior written permission. I have attached hereto as Exhibit A a
list describing all Prior Inventions that relate to the Company’s current or
anticipated business, products, or research and development or, if no such list
is attached, I represent and warrant that there are no such Prior Inventions.
Furthermore, I represent and warrant that if any Prior Inventions are included
on Exhibit A, they will not materially affect my ability to perform all
obligations under this Agreement.
C.Moral Rights. Any assignment to the Company of Inventions includes all rights
of attribution, paternity, integrity, modification, disclosure and withdrawal,
and any other rights throughout the world that may be known as or referred to as
“moral rights,” “artist’s rights,” “droit moral,” or the like (collectively,
“Moral Rights”). To the extent that Moral Rights cannot be assigned under
applicable law, I hereby waive and agree not to enforce any and all Moral
Rights, including, without limitation, any limitation on subsequent
modification, to the extent permitted under applicable law.
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. As between
the Company and myself, the records are and will be available to and remain the
sole property of the Company at all times.
E.Further Assurances. 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 the
Inventions in any and all countries, including 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 shall deem proper or necessary in order to apply for, register,
obtain, maintain, defend, and enforce such rights, and in order to deliver,
assign and convey to the Company, its successors, assigns, and nominees the sole
and exclusive rights, title, and interest in and to all Inventions, and
testifying in a suit or other proceeding relating to such Inventions. I further
agree that my obligations under this Section 3.E shall continue after the
termination of this Agreement.

Proprietary Rights Agreement - 3

--------------------------------------------------------------------------------

F.Attorney-in-Fact. I agree that, if the Company is unable because of my
unavailability, mental or physical incapacity, or for any other reason to secure
my signature with respect to any Inventions, including, for the purpose of
applying for or pursuing any application for any United States or foreign
patents or mask work or copyright registrations covering the Inventions assigned
to the Company in Section 3.A, 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 on my behalf to execute and file any papers and
oaths, and to do all other lawfully permitted acts with respect to such
Inventions to further the prosecution and issuance of patents, copyright and
mask work registrations with the same legal force and effect as if executed by
me. This power of attorney shall be deemed coupled with an interest, and shall
be irrevocable.
G.Exception to Assignments. I UNDERSTAND THAT THE PROVISIONS OF THIS AGREEMENT
REQUIRING ASSIGNMENT OF INVENTIONS (AS DEFINED UNDER SECTION 3.A ABOVE) TO THE
COMPANY DO NOT APPLY TO ANY INVENTION FOR WHICH NO EQUIPMENT SUPPLIES, FACILITY,
OR TRADE SECRET INFORMATION OF THE COMPANY WAS USED AND WHICH WAS DEVELOPED
ENTIRELY ON MY OWN TIME (AN “OTHER INVENTION”) EXCEPT FOR THOSE OTHER INVENTIONS
THAT RELATE: (A) DIRECTLY TO THE BUSINESS OF THE COMPANY; (B) TO THE COMPANY’S
ACTUAL OR DEMONSTRABLY ANTICIPATED RESEARCH OR DEVELOPMENT; OR (C) RESULT FROM
ANY WORK I PERFORM FOR THE COMPANY. 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.
I WILL ADVISE THE COMPANY PROMPTLY IN WRITING OF ANY INVENTIONS THAT I BELIEVE
MEET THE ABOVE CRITERIA AND ARE NOT OTHERWISE DISCLOSED ON EXHIBIT A TO PERMIT A
DETERMINATION OF OWNERSHIP BY THE COMPANY. ANY SUCH DISCLOSURE WILL BE RECEIVED
IN CONFIDENCE.
4.CONFLICTING OBLIGATIONS
A.Current Obligations. I agree that during my employment with the Company, I
will not engage in or undertake any other employment, occupation, consulting

nor will I engage in any other activities that conflict with my obligations to
the Company.
B.Prior Relationships. Without limiting Section 4.A, I represent and warrant
that I have no other agreements, relationships, or commitments to any other
person or entity that conflict with the provisions of this Agreement, 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 (and/or other third parties I have performed services for
in accordance with the terms of my applicable agreement). 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 with a third party 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.

(24) months immediately following the termination of my relationship with the
Company, I agree to provide written notification to the Company as to the name

general description of my duties and responsibilities, at least three
(3) business days prior to starting such employment.
B.    No Solicitation.
(1)    Non-Solicitation of Customers. I agree that for a period of twelve (12)
months immediately following the termination of my relationship with the Company
for any reason, whether with or without cause, at the option either of the

into, any business relationship with the Company, nor shall I otherwise

C.    Acknowledgements. I acknowledge that I will derive significant value from
the Company’s agreement to provide me with Company Confidential Information to
enable me to optimize the performance of my duties to the Company.  I further
acknowledge that my fulfillment of the obligations contained in this Agreement,
including, but not limited to, my obligation neither to disclose nor to use
Company Confidential Information other than for the Company’s exclusive benefit
and my obligations not to compete and not to solicit contained in subsections
(A) and (B) above, is necessary to protect Company Confidential Information and,
consequently, to preserve the value and goodwill of the Company.  I also
acknowledge the time, geographic and scope limitations of my obligations under
subsections (A) and (B) above are fair and reasonable in all respects,
especially in light of the Company’s need to protect Company Confidential
Information and the scope and nature of the Company’s business, and that I will
not be precluded from gainful employment if I am obligated not to compete with
the Company or solicit its customers, employees, or others during the period and
within the Territory as described above. In the event of my breach or violation
of this Section 8, or good faith allegation by the Company of my breach or
violation of this Section 8, the restricted periods set forth in this Section 8
shall be tolled until such breach or violation, or dispute related to an
allegation by the Company that I have breached or violated this Section 8, has
been duly cured or resolved, as applicable. I agree that nothing in this Section
8 shall affect my continuing obligations under this Agreement during and after
this twelve (12) month period, including, without limitation, my obligations
under Section Error! Reference source not found..
D.    Separate Covenants. The covenants contained in subsections (A) and (B)
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 subsections (A) and (B) above.  If, in any judicial or
arbitral proceeding, a court or arbitrator refuses to enforce any of such
separate covenants (or part thereof), then such unenforceable covenant (or such
part) shall be revised, or if revision is not permitted it shall be eliminated
from this Agreement, to the extent necessary to permit the remaining covenants
(or portions thereof) to be enforced.  In the event the provisions of
subsections (A) and (B) above are deemed to exceed the time, geographic or scope
limitations permitted by law, then such provisions shall be reformed to the
maximum time, geographic or scope limitations, then permitted by such law. In
the event that the applicable court or arbitrator does not exercise the power
granted to it in the prior sentence, I and the Company agree to replace such
invalid or unenforceable term or provision with a valid and enforceable term or
provision that will achieve, to the extent possible, the economic, business and
other purposes of such invalid or unenforceable term.
9.CONFLICT OF INTEREST GUIDELINES
I agree to diligently adhere to all policies of the Company, including the
Company’s insider trading policies, any employee handbook or manual, any code of
ethics, or any other Company policies as may be in effect from time to time
during my employment.

Electronic Media Equipment or personal Electronic Media Systems or other
personal property to review, retrieve, destroy, or ensure the permanent deletion
of Company information from such equipment or systems or property or take such
other actions that are needed to protect the Company or Company property, as
determined by the Company reasonably and in good faith.
I am aware that the Company has or may acquire software and systems that are
capable of monitoring and recording all Company network traffic to and from any

the Company’s internal networks. The Company further reserves the right to
retrieve previously deleted messages from e-mail or voicemail and monitor usage
of the Internet, including websites visited and any information I have
downloaded. In addition, the Company may review Internet and technology systems
activity and analyze usage patterns, and may choose to publicize this data to
assure that technology systems are devoted to legitimate business purposes.

A.Arbitration. IN CONSIDERATION OF MY EMPLOYMENT WITH THE COMPANY, ITS PROMISE
TO ARBITRATE ALL EMPLOYMENT-RELATED DISPUTES WITH ME, AND MY RECEIPT OF
COMPENSATION, AND OTHER COMPANY BENEFITS, AT PRESENT AND IN THE FUTURE, I AGREE

WHERE PERMITTED BY APPLICABLE LAW. I AGREE THAT THE DECREE OR AWARD RENDERED BY
THE ARBITRATOR MAY BE ENTERED AS A FINAL AND BINDING JUDGMENT IN ANY COURT
HAVING JURISDICTION THEREOF. I UNDERSTAND THAT THE COMPANY WILL PAY FOR ANY
ADMINISTRATIVE OR HEARING FEES CHARGED BY THE ARBITRATOR OR JAMS EXCEPT THAT I
SHALL PAY ANY FILING FEES ASSOCIATED WITH ANY ARBITRATION THAT I INITIATE, BUT
ONLY SO MUCH OF THE FILING FEES AS I WOULD HAVE INSTEAD PAID HAD I FILED A
COMPLAINT IN A COURT OF LAW. I AGREE THAT THE ARBITRATOR SHALL ADMINISTER AND
CONDUCT ANY ARBITRATION IN ACCORDANCE WITH TEXAS LAW, INCLUDING THE TEXAS RULES
OF CIVIL PROCEDURE AND THE TEXAS RULES OF EVIDENCE, AND THAT THE ARBITRATOR
SHALL APPLY SUBSTANTIVE AND PROCEDURAL TEXAS LAW TO ANY DISPUTE OR CLAIM,
WITHOUT REFERENCE TO RULES OF CONFLICT-OF-LAW. TO THE EXTENT THAT THE JAMS RULES
CONFLICT WITH TEXAS LAW, TEXAS LAW SHALL TAKE PRECEDENCE. I AGREE THAT ANY
ARBITRATION HEREUNDER SHALL BE CONDUCTED IN TRAVIS COUNTY, TEXAS.

C.Remedy. EXCEPT AS PROVIDED BY THE FAA OR THIS AGREEMENT, ARBITRATION SHALL BE

NEITHER I NOR THE COMPANY WILL BE PERMITTED TO PURSUE OR PARTICIPATE IN A COURT
ACTION REGARDING CLAIMS THAT ARE SUBJECT TO ARBITRATION. Administrative Relief.
I UNDERSTAND THAT THIS AGREEMENT DOES NOT PROHIBIT ME FROM PURSUING AN
ADMINISTRATIVE CLAIM WITH A LOCAL, STATE, OR FEDERAL ADMINISTRATIVE BODY OR
GOVERNMENT AGENCY THAT IS AUTHORIZED TO ENFORCE OR ADMINISTER LAWS RELATED TO
EMPLOYMENT, INCLUDING, BUT NOT LIMITED TO, THE TEXAS WORKFORCE COMMISSION, THE
EQUAL EMPLOYMENT OPPORTUNITY COMMISSION, OR THE NATIONAL LABOR RELATIONS BOARD,
THE SECURITIES AND EXCHANGE COMMISSION, OR THE WORKERS’ COMPENSATION BOARD. THIS
AGREEMENT DOES, HOWEVER, PRECLUDE ME FROM PURSUING A COURT ACTION REGARDING ANY
SUCH CLAIM, EXCEPT AS PERMITTED BY LAW.
D.Voluntary Agreement. I ACKNOWLEDGE AND AGREE THAT I AM EXECUTING THIS
AGREEMENT VOLUNTARILY AND WITHOUT DURESS OR UNDUE INFLUENCE BY THE COMPANY OR
ANYONE ELSE. I FURTHER ACKNOWLEDGE AND AGREE THAT I HAVE CAREFULLY READ THE

HAVE BEEN PROVIDED AN OPPORTUNITY TO SEEK THE ADVICE OF AN ATTORNEY OF MY CHOICE
BEFORE SIGNING THIS AGREEMENT.
13.MISCELLANEOUS
A.Governing Law; Consent to Personal Jurisdiction. With the exception of those
arbitration requirements set forth in Section 12 above that are governed by the
FAA, this Agreement will be governed by the laws of the State of Texas without
regard to Texas’ conflicts-of-law rules that may result in the application of
the laws of any jurisdiction other than Texas. To the extent that any lawsuit is
permitted under this Agreement, I hereby expressly consent to the personal and
exclusive jurisdiction and venue of the state and federal courts located in or
having jurisdiction over Travis County, Texas for any lawsuit filed against me
by the Company.
B.Assignability. This Agreement will be binding upon my heirs, executors,
assigns, administrators, and other legal representatives, and will be for the
benefit of the Company, its successors, and its assigns. The Associated Third
Parties are intended third-party beneficiaries to this Agreement with respect to
my obligations in Section 2.D. Notwithstanding anything to the contrary herein,
the Company may assign this Agreement and its rights and obligations under this
Agreement to any successor to all, or substantially all, of the Company’s
relevant assets, whether by merger, consolidation, reorganization,
reincorporation, sale of assets or stock, or otherwise. For the avoidance of
doubt, the Company’s successors and assigns are authorized to enforce the
Company’s rights under this Agreement.
C.Entire Agreement. This Agreement, together with the Exhibits herein and any
executed written offer letter between me and the Company, to the extent such
materials are not in conflict with this Agreement, sets forth the entire
agreement and understanding between the Company and me with respect to the
subject matter herein and supersedes all prior written and oral agreements,
discussions, or representations between us, including, but not limited to, any
representations made during my interview(s) or relocation negotiations. I
represent and warrant that I am not relying on any statement or representation
not contained in this Agreement. Any subsequent change or changes in my duties,
salary, compensation, conditions or any other terms of my employment will not
affect the validity or scope of this Agreement.
D.Headings. Headings are used in this Agreement for reference only and shall not
be considered when interpreting this Agreement.

Proprietary Rights Agreement - 10

--------------------------------------------------------------------------------

E.Severability. If a court or other body of competent jurisdiction finds, or the
parties mutually believe, any provision of this Agreement, or portion thereof,
to be invalid or unenforceable, such provision will be enforced to the maximum
extent permissible so as to effect the intent of the parties, and the remainder
of this Agreement will continue in full force and effect.
F.Modification, Waiver. No modification of or amendment to this Agreement, nor
any waiver of any rights under this Agreement, will be effective unless in a
writing signed by the Chairman of the Board of the Company (or a duly authorized
member of the Board) and me. Waiver by the Company of a breach of any provision
of this Agreement will not operate as a waiver of any other or subsequent
breach.
G.Survivorship. The rights and obligations of the parties to this Agreement will
survive termination of my employment with the Company.
H.Applicability to Past Activities. The Company and I acknowledge that I have
been engaged to provide services by the Company for a period of time prior to
the date of this Agreement (the “Prior Engagement Period”). Accordingly, I agree
that if and to the extent that, during the Prior Engagement Period: (i) I
received access to any information from or on behalf of Company that would have
been Company Confidential Information if I received access to such information
during the period of my employment with the Company under this Agreement; or
(ii) I conceived, created, authored, invented, developed or reduced to practice
any item, including any intellectual property rights with respect thereto, that
would have been an Invention if conceived, created, authored, invented,
developed or reduced to practice during the period of my employment with the
Company under this Agreement; then any such information shall be deemed Company
Confidential Information hereunder and any such item shall be deemed an
Invention hereunder, and this Agreement shall apply to such information or item
as if conceived, created, authored, invented, developed or reduced to practice
under this Agreement.
14.PROTECTED ACTIVITY NOT PROHIBITED
I understand that nothing in this Agreement limits or prohibits me from filing a
charge or complaint with, or otherwise communicating or cooperating with or
participating in any investigation or proceeding that may be conducted by, any
federal, state or local government agency or commission, including the
Securities and Exchange Commission, the Equal Employment Opportunity Commission,
the Occupational Safety and Health Administration, and the National Labor
Relations Board (“Government Agencies”), including disclosing documents or other
information as permitted by law, without giving notice to, or receiving
authorization from, the Company. Notwithstanding, in making any such disclosures
or communications, I agree to take all reasonable precautions to prevent any
unauthorized use or disclosure of any information that may constitute Company
Confidential Information to any parties other than the Government Agencies. I
further understand that I am not permitted to disclose the Company’s
attorney-client privileged communications or attorney work product. In addition,
I hereby acknowledge that the Company has provided me with notice in compliance
with the Defend Trade Secrets Act of 2016 regarding immunity from liability for
limited disclosures of trade secrets. The full text of the notice is attached in
