CELL BIOSCIENCES, INC. 

AMENDED AND RESTATED EXECUTIVE SEVERANCE BENEFIT PLAN 

Section 1. INTRODUCTION. 

The Cell Biosciences, Inc. Executive Severance Benefit Plan (the “Plan”), established effective April 28, 2009,
was amended and restated by the Board of Directors of Cell Biosciences, Inc. (the “Company”) on February 3, 2011. The purpose of the Plan is to provide for the payment of severance benefits to certain executive employees
of the Company upon the termination of their employment under specified circumstances. This Plan shall supersede any executive severance benefit agreement, plan, policy or practice previously maintained or entered into by the Company for or with any
Eligible Employee (as defined in Section 2(a)(1) below). This Plan document is also the Summary Plan Description for the Plan. 
 Section 2.
ELIGIBILITY FOR BENEFITS. 
 (a) General Rules. Subject to the requirements set forth
herein, the Company will grant severance benefits under the Plan to Eligible Employees. 
 (1) Definition of “Eligible
Employee.” For purposes of this Plan, Eligible Employees shall be those employees of the Company who are approved for participation in the Plan by the Company’s Board of Directors (the “Board”) as
listed in APPENDIX A hereto and who sign and return a Participation Agreement in the form attached hereto as APPENDIX B within thirty (30) days following his or her notification of selection for
participation in the Plan. The determination of whether an employee is an Eligible Employee shall be made by the Board, in its sole discretion, and such determination shall be binding and conclusive on all persons. If an employee who is deemed an
Eligible Employee by the Board has an individually negotiated employment agreement with the Company relating to severance benefits that is in effect on his or her termination date, the provisions of that agreement relating to severance benefits
shall be superseded by the terms of this Plan; provided, however, that all other remaining provisions of that agreement shall remain in effect. 

(2) Release of Claims. To be eligible to receive benefits under the Plan, an Eligible Employee must execute a general waiver
and release in substantially the form attached hereto as EXHIBIT A, EXHIBIT B or EXHIBIT C, as appropriate, within the time provided therein, and such release must become effective in
accordance with its terms, but in all cases the release must become effective within sixty (60) days following the date of the Eligible Employee’s “separation from service” (as defined under Treasury Regulation
Section 1.409A-1(h)). The Company, in its sole discretion, may modify the form of the required release to comply with applicable law and shall determine the form of the required release, which may be incorporated into a termination agreement or
other agreement with the Eligible Employee. Such release shall include confirmation of the Eligible Employee’s obligations under any confidentiality and/or proprietary information agreement and non-solicitation provisions as deemed appropriate
by the Company in its sole discretion, in accordance with applicable law. 

 (3) Return of Property. To be eligible to receive benefits under the Plan, an Eligible
Employee must return all Company property which he or she has had in his or her possession at any time, including but not limited to any materials which contain or embody any proprietary or confidential information of the Company and any computers,
mobile telephones or other physical property. 
 (b) Exceptions to Benefit Entitlement. An employee, including an employee who
otherwise is an Eligible Employee, will not receive benefits under the Plan if the employee is terminated for Cause (as defined herein), if the employee resigns without Good Reason (as defined herein), or if the employee’s employment is
terminated as a result of the employee’s death or disability, in each case as determined by the Company in its sole discretion. 
 Section 3.
AMOUNT OF BENEFIT. 
 (a) Termination without Cause. If, at any time other than
during the period commencing immediately prior to the effective date of a Change of Control (as defined herein) and ending twelve (12) months following the effective date of the Change of Control, the Company terminates an Eligible
Employee’s employment without Cause, and such termination constitutes a “separation from service” (as defined above), the Company shall provide the Eligible Employee with the following severance benefits: 

(1) A cash severance benefit in an amount equal to six (6) months of the Eligible Employee’s Base Salary (as defined
herein), subject to withholdings and deductions, which aggregate amount shall be paid in a lump sum on the first regular payroll date following the effective date of the Eligible Employee’s release of claims; provided, however, the
payment shall be made no later than March 15 of the year following the year of termination; and 
 (2) Provided that the
Eligible Employee is eligible to continue coverage under a health, dental, or vision plan sponsored by the Company under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) at the
time of the Eligible Employee’s termination and timely elects such continuation of coverage under COBRA, the Company will pay COBRA premiums on behalf of the Eligible Employee and his eligible dependents for a period of up to six
(6) months following the Eligible Employee’s termination of employment (but in no event longer that the date on which the Eligible Employee or his eligible dependents cease to be eligible for COBRA). Notwithstanding the previous sentence,
if the Company determines in its sole discretion that it cannot provide the foregoing COBRA benefit without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall
in lieu thereof provide to the Eligible Employee a taxable monthly payment in an amount equal to the monthly COBRA premium that the Eligible Employee would be required to pay to continue the Eligible Employee’s group health coverage in effect
on the date of the Eligible Employee’s termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made regardless of whether the Eligible Employee elects COBRA continuation coverage
and shall end on the earlier of (x) the date upon which the Eligible Employee obtains other employment or (y) the last day of the sixth (6th) calendar month following the Eligible
Employee’s termination date. Upon the conclusion of such period of insurance premium payments made by the Company, the Eligible Employee will be responsible for the entire payment of premiums required under COBRA for the

  
 2. 

 
duration of the COBRA period. No provision of this Plan will affect the continuation coverage rules under COBRA, except that the Company’s payment of any applicable insurance premiums will
be credited as payment by the Eligible Employee for purposes of the Eligible Employee’s payment required under COBRA. Therefore, the period during which an Eligible Employee may elect to continue the Company’s health, dental, or vision
plan coverage at his or her own expense under COBRA, the length of time during which COBRA coverage will be made available to the Eligible Employee, and all other rights and obligations of the Eligible Employee under COBRA (except the obligation to
pay insurance premiums that the Company pays in accordance with the foregoing) will be applied in the same manner that such rules would apply in the absence of this Plan. For purposes of this Section 3(a)(2), (i) references to COBRA shall
be deemed to refer also to analogous provisions of state law and (ii) any applicable insurance premiums that are paid by the Company shall not include any amounts payable by the Eligible Employee under an Internal Revenue Code Section 125
health care reimbursement plan, which amounts, if any, are the sole responsibility of the Eligible Employee. 
 (b) Termination without
Cause or Resignation for Good Reason Following a Change of Control. If the Company terminates an Eligible Employee’s employment without Cause, or the Eligible Employee resigns for Good Reason, in either case, at any time during the period
commencing immediately prior to the effective date of a Change of Control and ending twelve (12) months following the effective date of the Change of Control, and provided such termination constitutes a “separation from service”, then
the Company shall provide the Eligible Employee with the following severance benefits: 
 (1) A cash severance benefit in an amount
equal to the sum of (i) nine (9) months of the Eligible Employee’s Base Salary, (ii) the prior year’s annual incentive bonus amount actually earned by the Eligible Employee (if not yet paid), (iii) seventy-five percent
(75%) of the Eligible Employee’s Target Bonus (as defined below) for the year in which the termination occurs, and (iv) a pro rata portion of the Eligible Employee’s Target Bonus based on the number of months worked during the
year in which the termination occurs, subject to withholdings and deductions, which aggregate amount shall be paid in a lump sum on the first regular payroll date following the effective date of the Eligible Employee’s release of claims;
provided, however, the payment shall be made later than March 15 of the year following the year of termination; 
 (2)
The same COBRA benefit provided in Section 3(a)(2) except that such benefit shall be for up to nine (9) months; and 
 (3)
Full acceleration of the vesting of the unvested shares of common stock held by the Eligible Employee that were issued pursuant to his or her compensatory equity awards and of the unvested shares of common stock subject to unexercised stock options
then held by the Eligible Employee. 
 (c) Definitions. 

(1) Base Salary. For purposes of calculating Plan benefits, “Base Salary” shall mean the Eligible
Employee’s base pay (excluding incentive pay, premium pay, commissions, overtime, bonuses and other forms of variable compensation), at the rate in effect 

  
 3. 

 
during the last regularly scheduled payroll period immediately preceding the Eligible Employee’s termination (ignoring any reduction in Base Salary that is the basis for the Eligible
Employee’s resignation for Good Reason, as applicable). 
 (2) Cause. For purposes of this Plan,
“Cause” shall mean that the Eligible Employee committed, or there has occurred, one or more of the following: (a) conviction of, a guilty plea with respect to, or a plea of nolo contendere to a charge that the
Eligible Employee has committed a felony under the laws of the United States or of any state of a crime involving moral turpitude, including, but not limited to, fraud, theft, embezzlement or any crime that results in or is intended to result in
personal enrichment at the expense of the Company; (b) material breach of any agreement entered into between the Eligible Employee and the Company that impairs the Company’s interest therein; (c) willful misconduct, or gross neglect
by such Eligible Employee of his or her duties, if such conduct is not cured within seven (7) days of the Eligible Employee’s receipt of written notice (provided that such conduct can reasonably be cured); (d) an unauthorized use or
disclosure of the Company’s confidential information or trade secrets; or (e) engagement in any activity that constitutes a material conflict of interest with the Company. The Eligible Employee’s death or physical or mental disability
shall also constitute Cause for termination hereunder. Cause to terminate employment based on the Eligible Employee’s physical or mental disability shall exist if any illness, disability or other incapacity renders the Eligible Employee
physically or mentally unable to regularly perform his or her duties hereunder for a period in excess of sixty (60) consecutive days or more than ninety (90) days in any consecutive twelve (12) month period. The Board of Directors
shall make a good faith determination of whether the Eligible Employee is physically or mentally unable to regularly perform his or her duties, subject to its review and consideration of any physical and/or mental health information provided to it
by the Eligible Employee. 
 (3) Change of Control. For purposes of the Plan, a “Change of Control” shall
have the meaning given to the term “Change in Control” as set forth in the Company’s 2003 Stock Option/Stock Issuance Plan in effect on the date hereof and as amended and/or restated from time to time. Notwithstanding the foregoing,
if the Company or a successor hereto subsequently determines that the Plan Payments (as defined below) constitute deferred compensation under Section 409A (as defined below), a “Change of Control” shall be limited to a transaction
satisfying the requirements of Treasury Regulation Sections 1.409A-3(c)(1) (regarding alternative payment schedules) and 1.409A-3(i)(5) (defining a change in control event, without regard to the alternative definitions thereunder). 

(4) Good Reason. For purposes of this Plan, “Good Reason” shall mean the Eligible Employee’s resignation
from all positions he or she then-holds with the Company if any one of the following events occurs without his or her consent: (A) (I) any material reduction of the Eligible Employee’s then current annual base salary, except to the
extent that the annual base salary of all other officers of the Company is similarly reduced; (II) any material diminution of the Eligible Employee’s authority, duties or responsibilities; (III) any material diminution in the authority, duties
or responsibilities of the supervisor to whom the service provider is required to report, (IV) any requirement that the Eligible Employee relocate to a work site that would increase his or her one-way commute distance by more than thirty-five
(35) miles; or (V) any material breach by the Company of its obligations under this Plan or the employment agreement between the Company and the Eligible Employee, (B) the Eligible 

  
 4. 

 
Employee provides written notice to the Company’s Chief Executive Officer within the forty-five (45) days immediately following such material change or reduction, (C) such material
change or reduction is not remedied by the Company within forty-five (45) days following the Company’s receipt of such written notice, and (D) the Eligible Employee’s resignation is effective not later than thirty (30) days
after the expiration of such cure period. 
 (5) Target Bonus. For purposes of calculating Plan benefits, “Target
Bonus” shall mean the greater of (i) the Eligible Employee’s target annual incentive bonus amount as most recently determined for the year of termination by the Company, generally (but not necessarily) expressed as a
percentage of Base Salary or (ii) the Eligible Employee’s actual annual incentive bonus amount paid for the prior calendar year. 

(d) Other Employee Benefits. All other benefits (such as life insurance, disability coverage, and 401(k) plan coverage) terminate as of
the Eligible Employee’s termination date (except to the extent that a conversion privilege at the Eligible Employee’s expense may be available thereunder). 

(e) Certain Reductions. The Company shall reduce an Eligible Employee’s severance benefits, to the greatest extent possible, by
any other severance benefits, pay in lieu of notice, or other similar benefits payable to the Eligible Employee by the Company that become payable in connection with the Eligible Employee’s termination of employment pursuant to (i) any
applicable legal requirement, including, without limitation, the Worker Adjustment and Retraining Notification Act, or (ii) any Company policy or practice providing for the Eligible Employee to remain on the payroll for a limited period of time
after being given notice of the termination of the Eligible Employee’s employment. The benefits provided under this Plan are intended to satisfy, to the greatest extent possible, any and all statutory obligations that may arise out of an
Eligible Employee’s termination of employment, and the Plan Administrator shall so construe and implement the terms of the Plan. In the Company’s sole discretion, such reductions may be applied on a retroactive basis, with severance
benefits previously paid being recharacterized as payments pursuant to the Company’s statutory obligation. 
 Section 4.
LIMITATIONS ON PAYMENTS. 
 (a) Taxes and Offsets. All payments under the Plan will
be subject to applicable withholding for federal, state and local taxes. If an Eligible Employee is indebted to the Company at his or her termination date, the Company reserves the right to offset any severance payments under the Plan by the amount
of such indebtedness. In no event shall payment of any Plan benefit be made prior to the Eligible Employee’s separation from service or prior to the effective date of the release described in Section 2(a)(2). 

(b) Best After Tax. If any payment or benefit (including payments and benefits pursuant to this Agreement) that an Eligible Employee
would receive in connection with a change of control transaction from the Company or otherwise (“Payment”) would (x) constitute a “parachute payment” within the meaning of Section 280G of the Internal
Revenue Code of 1986, as amended (the “Code”), and (y) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Company shall cause
to be determined, before any amounts of the Payment are paid to the Eligible Employee, which of the 

  
 5. 

 
following two alternative forms of payment would maximize the Eligible Employee’s after-tax proceeds: (i) payment in full of the entire amount of the Payment (a “Full
Payment”), or (ii) payment of only a part of the Payment so that the Eligible Employee receives the largest payment possible without the imposition of the Excise Tax (a “Reduced Payment”), whichever amount
results in the Participant’s receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. For purposes of determining whether to
make a Full Payment or a Reduced Payment, the Company shall cause to be taken into account all applicable federal, state and local income and employment taxes and the Excise Tax (all computed at the highest applicable marginal rate, net of the
maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes). If a Reduced Payment is made, (A) the Payment shall be paid only to the extent permitted under the Reduced Payment alternative,
and the Eligible Employee shall have no rights to any additional payments and/or benefits constituting the Payment, and (B) reduction in payments and/or benefits shall occur in the following order: (1) reduction of cash payments;
(2) cancellation of accelerated vesting of equity awards other than stock options; (3) cancellation of accelerated vesting of stock options; and (4) reduction of other benefits paid to the Eligible Employee. In the event that
acceleration of compensation from the Eligible Employee’s equity awards is to be reduced, such acceleration of vesting shall be canceled in the reverse order of the date of grant. 

The independent professional firm engaged by the Company for general tax audit purposes as of the day prior to the effective date of the
Change of Control shall make all determinations required to be made under this Section 4(b). If the firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change of Control, the
Company shall appoint a nationally recognized independent professional firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such firm required to be made hereunder. 

The firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the
Company and the Eligible Employee within fifteen (15) calendar days after the date on which the Eligible Employee’s right to a Payment is triggered (if requested at that time by the Company or the Eligible Employee) or such other time as
requested by the Company or the Eligible Employee. If the firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish the Company and the Eligible Employee
with a statement reasonably acceptable to the Eligible Employee that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the firm made hereunder shall be final, binding and conclusive upon the Company and the
Eligible Employee. 
 (c) Code Section 409A. It is intended that (x) each installment of the severance payments and benefits provided
under the Plan (the “Plan Payments”) is a separate “payment” for purposes of Code Section 409A (together, with any state law of similar effect, “Section 409A”), (y) all of the Plan Payments
satisfy, to the greatest extent possible, the exemptions from the application of Section 409A provided under of Treasury Regulation Sections 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and (z) this Plan will be construed to the greatest
extent possible as consistent with those provisions. If the Company (or, if applicable, the successor entity thereto) determines that the Plan Payments constitute “deferred 

  
 6. 

 
compensation” under Section 409A and an Eligible Employee is a “specified employee” of the Company or any successor entity thereto, as such term is defined in
Section 409A(a)(2)(B)(i) (a “Specified Employee”) on his or her separation from service, then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the
timing of the Plan Payments shall be delayed as follows: on the earlier to occur of (i) the date that is six (6) months and one (1) day after the date of his or her separation from service or (ii) the date of the Eligible
Employee’s death (such earlier date, the “Delayed Initial Payment Date”), the Company (or the successor entity thereto, as applicable) shall (A) pay to the Eligible Employee a lump sum amount equal to the sum of the
Plan Payments that the Eligible Employee would otherwise have received through the Delayed Initial Payment Date (including reimbursement for any premiums paid by the Eligible Employee for health insurance coverage under COBRA) if the commencement of
the payment of the Plan Payments had not been delayed pursuant to this Section 4(c) and (B) commence paying the balance of the Plan Payments in accordance with the applicable payment schedules set forth in Section 3 above. 

Section 5. REEMPLOYMENT. 

In the event of an Eligible Employee’s reemployment by the Company during the period of time in respect of which Plan Payments have been
paid, the Company, in its sole discretion, may require such Eligible Employee to repay to the Company all or a portion of such Plan Payments as a condition of reemployment. 

Section 6. RIGHT TO INTERPRET PLAN; AMENDMENT AND
TERMINATION. 
 (a) Exclusive Discretion. The Plan Administrator (set forth in Section 11(d)) shall have the
exclusive discretion and authority to establish rules, forms, and procedures for the administration of the Plan and to construe and interpret the Plan and to decide any and all questions of fact, interpretation, definition, computation or
administration arising in connection with the operation of the Plan, including, but not limited to, the eligibility to participate in the Plan and amount of benefits paid under the Plan. The rules, interpretations, computations and other actions of
the Plan Administrator shall be binding and conclusive on all persons. 
 (b) Amendment or Termination. The Company reserves the
right to amend or terminate this Plan (including Appendix A) or the benefits provided hereunder at any time prior to a Change of Control; provided, however, that no such amendment or termination shall materially adversely impair the rights of
any Eligible Employee under the Plan without his or her written consent. 
 Section 7. NO IMPLIED
EMPLOYMENT CONTRACT. 
 The Plan shall not be deemed to (i) give any employee or other person any
right to be retained in the employ of the Company or (ii) interfere with the right of the Company to discharge any employee or other person at any time, with or without cause, which right is hereby reserved. 

  
 7. 

 Section 8. LEGAL CONSTRUCTION. 

This Plan is intended to be governed by and shall be construed in accordance with the Employee Retirement Income Security Act of 1974
(“ERISA”) and, to the extent not preempted by ERISA, the laws of the State of California. 
 Section 9.
CLAIMS, INQUIRIES AND APPEALS. 
 (a) Applications for Benefits and
Inquiries. Any application for benefits, inquiries about the Plan or inquiries about present or future rights under the Plan must be submitted to the Plan Administrator in writing by an applicant (or his or her authorized representative). 

(b) Denial of Claims. In the event that any application for benefits is denied in whole or in part, the Plan Administrator must provide
the applicant with written or electronic notice of the denial of the application, and of the applicant’s right to review the denial. Any electronic notice will comply with the regulations of the U.S. Department of Labor. The notice of denial
will be set forth in a manner designed to be understood by the applicant and will include the following: 
 (1) the specific reason
or reasons for the denial; 
 (2) references to the specific Plan provisions upon which the denial is based; 

(3) a description of any additional information or material that the Plan Administrator needs to complete the review and an
explanation of why such information or material is necessary; and 
 (4) an explanation of the Plan’s review procedures and the
time limits applicable to such procedures, including a statement of the applicant’s right to bring a civil action under section 502(a) of ERISA following a denial on review of the claim, as described in Section 9(d) below. 

This notice of denial will be given to the applicant within ninety (90) days after the Plan Administrator receives the application,
unless special circumstances require an extension of time, in which case, the Plan Administrator has up to an additional ninety (90) days for processing the application. If an extension of time for processing is required, written notice of the
extension will be furnished to the applicant before the end of the initial ninety (90) day period. 
 This notice of extension will
describe the special circumstances necessitating the additional time and the date by which the Plan Administrator is to render its decision on the application. 

(c) Request for a Review. Any person (or that person’s authorized representative) for whom an application for benefits is denied,
in whole or in part, may appeal the denial by submitting a request for a review to the Plan Administrator within sixty (60) days after the application is denied. A request for a review shall be in writing and shall be addressed to the Plan
Administrator. 

  
 8. 

 A request for review must set forth all of the grounds on which it is based, all facts in support
of the request and any other matters that the applicant feels are pertinent. The applicant (or his or her representative) shall have the opportunity to submit (or the Plan Administrator may require the applicant to submit) written comments,
documents, records, and other information relating to his or her claim. The applicant (or his or her representative) shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other
information relevant to his or her claim. The review shall take into account all comments, documents, records and other information submitted by the applicant (or his or her representative) relating to the claim, without regard to whether such
information was submitted or considered in the initial benefit determination. 
 (d) Decision on Review. The Plan Administrator will
act on each request for review within sixty (60) days after receipt of the request, unless special circumstances require an extension of time (not to exceed an additional sixty (60) days), for processing the request for a review. If an
extension for review is required, written notice of the extension will be furnished to the applicant within the initial sixty (60) day period. This notice of extension will describe the special circumstances necessitating the additional time
and the date by which the Plan Administrator is to render its decision on the review. The Plan Administrator will give prompt, written or electronic notice of its decision to the applicant. Any electronic notice will comply with the regulations of
the U.S. Department of Labor. In the event that the Plan Administrator confirms the denial of the application for benefits in whole or in part, the notice will set forth, in a manner calculated to be understood by the applicant, the following: 

(1) the specific reason or reasons for the denial; 

(2) references to the specific Plan provisions upon which the denial is based; 

(3) a statement that the applicant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all
documents, records and other information relevant to his or her claim; and 
 (4) a statement of the applicant’s right to bring
a civil action under section 502(a) of ERISA. 
 (e) Rules and Procedures. The Plan Administrator will establish rules and
procedures, consistent with the Plan and with ERISA, as necessary and appropriate in carrying out its responsibilities in reviewing benefit claims. The Plan Administrator may require an applicant who wishes to submit additional information in
connection with an appeal from the denial of benefits to do so at the applicant’s own expense. 
 (f) Exhaustion of Remedies. No
legal action for benefits under the Plan may be brought until the applicant (i) has submitted a written application for benefits in accordance with the procedures described by Section 9(a) above, (ii) has been notified by the Plan
Administrator that the application is denied, (iii) has filed a written request for a review of the 

  
 9. 

 
application in accordance with the appeal procedure described in Section 9(c) above, and (iv) has been notified that the Plan Administrator has denied the appeal. Notwithstanding the
foregoing, if the Plan Administrator does not respond to a Participant’s claim or appeal within the relevant time limits specified in this Section 9, the Participant may bring legal action for benefits under the Plan pursuant to
Section 502(a) of ERISA.

 Section 12. STATEMENT OF ERISA
RIGHTS. 
 Participants in this Plan (which is a welfare benefit plan sponsored by Cell Biosciences, Inc.) are entitled to
certain rights and protections under ERISA. If you are an Eligible Employee, you are considered a participant in the Plan and, under ERISA, you are entitled to: 

(a) Receive Information About Your Plan and Benefits 

(1) Examine, without charge, at the Plan Administrator’s office and at other specified locations, such as worksites, all
documents governing the Plan and a copy of the latest annual report (Form 5500 Series), if applicable, filed by the Plan with the U.S. Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security Administration;

  
 10. 

 (2) Obtain, upon written request to the Plan Administrator, copies of documents governing
the operation of the Plan and copies of the latest annual report (Form 5500 Series), if applicable, and an updated (as necessary) Summary Plan Description. The Administrator may make a reasonable charge for the copies; and 

(3) Receive a summary of the Plan’s annual financial report, if applicable. The Plan Administrator is required by law to furnish
each participant with a copy of this summary annual report. 
 (b) Prudent Actions by Plan Fiduciaries. In addition to creating
rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan. The people who operate the Plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in
the interest of you and other Plan participants and beneficiaries. No one, including your employer, your union or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a Plan benefit or
exercising your rights under ERISA. 
 (c) Enforce Your Rights. If your claim for a Plan benefit is denied or ignored, in whole or in
part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules. 

Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request a copy of Plan documents or the latest
annual report from the Plan, if applicable, and do not receive them within 30 days, you may file suit in a Federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you
receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. 
 If you have a
claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or Federal court. 
 If you are
discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court
may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous. 

(d) Assistance with Your Questions. If you have any questions about the Plan, you should contact the Plan Administrator. If you have
any questions about this statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you should contact the nearest office of the Employee Benefits Security Administration, U.S.
Department of Labor, listed in your telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W., Washington, D.C. 20210. You may also
obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

without regard to whether or not such person or entity actively assumes the obligations hereunder. 
 (c) Waiver. Any party’s

 Exhibit 10.15 

PROTEINSIMPLE 

MANAGEMENT RETENTION BONUS PLAN 

This Management Retention Bonus Plan (the “Plan”), established effective January 21, 2010 by ProteinSimple, a
Delaware corporation (the “Company”),was amended by the Board on February 3, 2011 and July 23, 2013. 
 1. Purpose of
the Plan. The Company considers it essential to the operation of the Company that its key employees be retained through a potential Corporate Transaction and wants to augment the incentives provided by existing equity ownership and stock option
grants. The purpose of the Plan is to establish a retention bonus pool to provide incentive for key employees to continue in the service of the Company through a potential Corporate Transaction. The Plan is meant to supplement and work in
conjunction with, and not to replace, the Company’s other incentive programs, such as its option plans, severance arrangements and other benefits plans, in order to achieve the foregoing purposes. 

2. Definitions. 
 2.1
“Board” means the Board of Directors of the Company, with any members thereof who are Participants hereunder abstaining from any actions taken hereunder. 

2.2 “Cause” will mean, with respect to a particular Participant, that the
Participant committed, or there has occurred, one or more of the following: (a) conviction of, a guilty plea with respect to, or a plea of nolo contendere to a charge that the Participant has committed a felony under the laws of the
United States or of any state of a crime involving moral turpitude, including, but not limited to, fraud, theft, embezzlement or any crime that results in or is intended to result in personal enrichment at the expense of the Company;
(b) material breach of any agreement entered into between the Participant and the Company that impairs the Company’s interest therein; (c) willful misconduct, or gross neglect by such Participant of his or her duties, if such conduct
is not cured within seven (7) days of the Participant’s receipt of written notice (provided that such conduct can reasonably be cured); (d) an unauthorized use or disclosure of the Company’s confidential information or trade
secrets; or (e) engagement in any activity that constitutes a material conflict of interest with the Company. The Participant’s death or physical or mental disability shall also constitute Cause for termination hereunder. Cause to
terminate employment based on the Participant’s physical or mental disability shall exist if any illness, disability or other incapacity renders the Participant physically or mentally unable to regularly perform his or her duties hereunder for
a period in excess of sixty (60) consecutive days or more than ninety (90) days in any consecutive twelve (12) month period. The Administrator shall make a good faith determination of whether the Participant is physically or mentally
unable to regularly perform his or her duties, subject to its review and consideration of any physical and/or mental health information provided to it by the Participant.  

2.3 “Closing” will mean the initial closing of the Corporate Transaction as defined in the definitive agreement
executed in connection with the Corporate Transaction. In the case of a series of transactions constituting a Corporate Transaction, “Closing” means the first closing that satisfies the threshold of the definition for a
Corporate Transaction. 

 2.4 “Code” means the U.S. Internal Revenue Code of 1986, as
amended. 
 2.5 “Contingent Consideration” means the sum of any cash and the Fair Market Value of any
securities or other property (after the payment of transaction fees and expenses, including, without limitation, payments to investment bankers and attorneys in connection with a Corporate Transaction) that would be, but for the existence of the
Plan, received by the Company or the Securityholders in respect of equity securities of the Company in connection with a Corporate Transaction after the Closing, the receipt of which is contingent upon the passage of time or the occurrence or
non-occurrence of some future event(s) or circumstance(s), including, without limitation, amounts of consideration paid at a subsequent closing, and amounts of consideration subject to an escrow, a purchase price adjustment, an earn-out or indemnity
claims. 
 2.6 “Corporate Transaction” will mean the consummation of a
transaction or series of transactions that results in (i) any sale or other disposition of all or substantially all of the assets of the Company that occurs over a period of not more than twelve (12) months; or (ii) any person, or
more than one person acting as a group, acquiring ownership of stock of the Company, that together with the stock held by such person or group, constitutes more than 50% of the total fair market value or total voting power of the stock of such
corporation. However, a Corporate Transaction will not include (1) any consolidation or merger effected exclusively to change the domicile of the Company, or (2) any transaction or series of transactions principally for bona fide equity
financing purposes in which cash is received by the Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof. This definition of Corporate Transaction is intended to conform to the definitions of
“change in ownership of a corporation” and “change in ownership of a substantial portion of a corporation’s assets” provided in Treasury Regulation Sections 1.409A-3(i)(5)(v) and (vii). 

2.7 “Corporate Transaction Bonus” with respect to a Participant will be an amount
equal to the product of (i) the Participant’s Participation Percentage as of the Closing, multiplied by (ii) the Corporate Transaction Bonus Pool. 

2.8 “Corporate Transaction Bonus Pool” will be an amount of consideration equal to
either: (i) five percent (5%) of the Total Consideration if the Total Consideration for a Corporate Transaction is less than $275,000,000; (ii) six percent (6%) of the Total Consideration if the Total Consideration for a
Corporate Transaction is equal to or greater than $275,000,000 and less than or equal to $300,000,000; or (ii) seven (7%) of the Total Consideration if the Total Consideration for a Corporate Transaction is greater than $300,000,000.
Notwithstanding the foregoing, in the event that the aggregate amount payable to all Participants in connection with a Corporate Transaction with respect to actual shares of stock or shares of stock issuable pursuant to outstanding stock options of
the Participants (“Other Equity Payments”) and with respect to bonus payments that would be made under this Plan under the applicable percentage described above, exceeds 15.3% of the Total Consideration in the Corporate
Transaction, the amount of the Corporate Transaction Bonus Pool shall be reduced such that when added to the Other Equity Payments, the aggregate amount payable to the Participants in a Corporate Transaction shall not exceed 15.3% of the Total
Consideration.  

  
 2. 

 2.9 “Fair Market Value” will be the
value determined by the Board (or the Representative, as applicable) as of the applicable date in its sole discretion in accordance with Section Code 409A to the extent applicable, and such determination will be final and binding. 

 2.10 “Initial Consideration” means the sum of any cash and the
Fair Market Value of any securities or other property to be received by the Company or the Securityholders in respect of equity securities of the Company upon the Closing of the Corporate Transaction (including the total value of (i) any stock
option or warrant exercise proceeds, whether paid directly or net-exercised in connection with the Corporate Transaction and (ii) any payments made in connection with the Corporate Transaction pursuant to outstanding promissory notes previously
issued as consideration for the exercise of stock options) after the payment of transaction fees and expenses (including, without limitation, payments to investment bankers and attorneys in connection with a Corporate Transaction) that would be, but
for the existence of the Plan, legally available for payment or distribution to the Securityholders at the Closing. Initial Consideration does not include any Contingent Consideration.  

2.11 “Participant” will mean an employee of the Company holding the title of Vice
President or above who has been designated as a Participant by the Administrator and who has signed and returned a valid Participation Agreement to the Company within forty-five (45) days after being provided such agreement, as set forth on
EXHIBIT A hereto, as the same may be amended from time to time. 

2.12 “Participation Agreement” will mean an agreement between a Participant and the
Company in substantially the form of EXHIBIT B hereto. 
 2.13
“Participation Percentage” will mean the percentage determined in accordance with Section 4.1. 

2.14 “Representative” will mean one or more members of the Board or persons
designated by the Board prior to or in connection with a Corporate Transaction, provided no such persons may be Participants. 

2.15 “Resignation for Good Reason” will mean with respect to a particular Participant, the
Participant’s resignation from all positions he or she then holds with the Company, in a manner that constitutes a “separation from service” under Treasury Regulation Section 1.409A-1(h), as a result of the occurrence of any of
the following events, conditions or actions taken by the Company without Cause and without such Participant’s consent: (i) any material reduction of the Participant’s then current annual base salary, except to the extent that the
annual base salary of all other officers of the Company is similarly reduced; (ii) any material diminution of the Participant’s authority, duties or responsibilities; (iii) any material diminution in the authority, duties or
responsibilities of the supervisor to whom the Participant is required to report, (IV) any requirement that the Participant relocate to a work site that would increase his or her one-way commute distance by more than thirty-five (35) miles; or
(iv) any material breach by the Company of its obligations under this Plan or the employment agreement between the Company and the Participant; provided, however, that the Participant must (1) provide written notice of the occurrence of
such event to the Company’s Chief Executive Officer (or to the Board in the case of a Participant who is the Chief Executive Officer) within the forty-five (45)

  
 3. 

 
days immediately following the occurrence of such event, (2) allow the Company forty-five (45) days to cure such event or condition, and (3) if the Company does not cure such event
within such period, the resignation is effective not later than thirty (30) days after the conclusion of such cure period. 

2.16 “Securityholders” will mean the stockholders, option holders and warrant
holders of the Company.  
 2.17 “Total Consideration” means the
sum of the Initial Consideration and the Contingent Consideration.  
 3. Interpretation and Administration of the Plan. 

3.1 Prior to the Closing, the Plan will be interpreted and administered by the Compensation Committee of
the Board (the “Administrator”), whose actions in interpreting the terms of the Plan and administration of the Plan will be final and binding on all Participants. 

3.2 Upon and after the Closing, the Plan will be interpreted and administered in good faith by the Representative. All actions taken by
the Representative in interpreting the terms of the Plan and administration of the Plan will be final and binding on all Participants. 
 4.
Allocation of the Corporate Transaction Bonus Pool. 
 4.1 The Plan will operate through the award of Corporate Transaction Bonus
payments to Participants who meet the eligibility requirements of Section 5 and the conditions to receiving a Corporate Transaction Bonus set forth in the Plan. For each Participant, his or her Participation Percentage shall be a number equal
to a fraction, the numerator of which is the number of shares of the Company’s Common Stock held by the Participant (in actual shares of stock or shares of stock issuable pursuant to outstanding stock options) as of the Closing and the
denominator of which is the total number of shares of the Company’s Common Stock held by all Participants (in actual shares of stock or shares of stock issuable pursuant to outstanding stock options) as of the Closing.  

4.2 A Participation Agreement signed by a duly authorized officer of the Company and each Participant will be issued to each
Participant, which agreement will contain such terms as the Administrator deems necessary or advisable in the administration of the Plan.  
 5.
Eligibility to Earn a Corporate Transaction Bonus. 
 5.1 Except as otherwise provided in a Participant’s Participation
Agreement and Section 6 below, each Participant will become vested in the Participation Percentage awarded to him or her upon the Closing subject to the Participant’s continued service with the Company through the Closing; provided
however, that in the event the Closing occurs within sixty (60) days after a Participant’s termination of employment or service with the Company either (i) by the Company without Cause (and other than as a result of his or her death
or disability) or (ii) by the Participant pursuant to a Resignation for Good Reason, a Participant will still become fully vested in the Participation Percentage awarded to him or her upon the Closing. If a Participant’s Participation
Percentage fails to vest upon the Closing, then such Participant will not be entitled to receive any Corporate Transaction Bonus in respect of such Participation Percentage. 

  
 4. 

 5.2 Notwithstanding any provision to the contrary in the Plan, a Participant will not earn
or be entitled to any portion of the Corporate Transaction Bonus provided under the Plan until the Closing. 
 6. Payment of Corporate Transaction Bonus.

 6.1 If the conditions for earning the Corporate Transaction Bonus set forth in the Plan and the applicable Participation
Agreement are satisfied, each Participant will be entitled to earn and be paid his or her Corporate Transaction Bonus as follows: 
 (i)
A Participant will be paid the Corporate Transaction Bonus in a lump sum on the thirtieth (30th) day following the Closing, except as set forth in Section 6.1(ii)-(iii) below.

 (ii) To the extent the Total Consideration includes any Contingent Consideration, the portion of the Corporate Transaction Bonus
that may be earned and payable in respect of such amounts of Contingent Consideration will be subject to the same conditions (including but not limited to any escrow arrangement, indemnity obligation, or earn-out) (the
“Conditions”) on payment imposed on all other Securityholders with respect to their rights to the Contingent Consideration to the same extent the Conditions are imposed on the Contingent
Consideration (i.e., on a pro-rata basis) (such portion of the Corporate Transaction Bonus subject to the Conditions, the “Unvested Consideration”). Except as set forth in Section 6.1(iii)
below, the Unvested Consideration will be paid in a lump sum, as, if and when the Contingent Consideration is paid to the Securityholders, but in no event later than thirty (30) days following the date on which the applicable Condition is
satisfied. 
 (iii) To the extent that a Condition, when applied to the Corporate Transaction Bonus, would not constitute a
“substantial risk of forfeiture” (as defined in Treasury Regulations Section 1.409A-1(d)), such that the Unvested Consideration related to such Condition would not be reasonably likely to be
payable in compliance with either Treasury Regulation Section 1.409A-1(b)(4) or Treasury Regulation Section 1.409A-3(i)(5)(iv)(A), or to the extent the Administrator determines the Unvested Consideration is not otherwise payable in
compliance with or under an exemption from Section 409A, the Participant shall be paid the Unvested Consideration related to such Condition, subject to any reduction made by the Administrator based on the Fair Market Value (as of the Closing)
of the Unvested Consideration as a result of the existence of the Condition (that is, the present value of the Corporate Transaction Bonus that may be earned upon satisfaction of the Condition), in a lump sum on the thirtieth (30th) day following the effective date of the Corporate Transaction. 
 6.2 It is
intended that each installment of the payments provided under the Plan (the “Plan Payments”) is a separate “payment” for purposes
Section 1.409A-2(b)(2)(i) of the Treasury Regulations. For the avoidance of doubt, it is intended that the Plan Payments satisfy, to the greatest extent possible, the exemption from the application of Section 409A of the Code and the
Treasury Regulations and other guidance issued thereunder and any state law of similar effect (collectively “Section 409A”) provided under Treasury Regulations Section 1.409A-1(b)(4)

  
 5. 

 
and, to the extent not so exempt, that the Plan Payments comply, and the Plan be interpreted to the greatest extent possible as consistent, with Treasury Regulations
Section 1.409A-3(i)(5)(iv)(A) – that is, as “transaction-based compensation.” Therefore, no Plan Payments pursuant to Section 6.1(ii)-(iii) will be earned or paid after the fifth (5th) anniversary of the Closing
and the Participants will not be entitled to any payments under the Plan with respect to any Contingent Consideration after such date. 

6.3 The Corporate Transaction Bonus will be paid in the same forms and in the same proportions as the Total Consideration is paid by
the acquirer to the Securityholders.  
 6.4 In addition to any other restrictions imposed on the payments to be made pursuant
to the Plan, any securities that are issued to the Participants under the Plan will be subject to the same or similar restrictions as imposed by the acquiring company on the securities distributed to the Securityholders as part of the Total
Consideration on the terms set forth in the agreement pursuant to which the Corporate Transaction occurs. 
 7. Release. As a further
condition to earning a Corporate Transaction Bonus, a Participant must execute and allow to become effective a general release of claims in substantially the form of Exhibit C within thirty (30) days after the Closing. If any Participant
refuses to execute such release and allow it to become effective within such time period, then such Participant will not be eligible to earn a Corporate Transaction Bonus and the Corporate Transaction Bonus otherwise payable to such Participant will
be forfeited by such Participant. 
 8. Withholding of Compensation. The Company or the acquirer in a Corporate Transaction will withhold from any
payments under the Plan and from any other amounts payable to a Participant by the Company or such acquirer any amount required to satisfy the income and employment tax withholding obligations arising under applicable federal and state laws in
respect of the Corporate Transaction Bonus. Without limiting the forgoing, the Company or such acquirer may, in it sole discretion, satisfy the tax withholding obligations by withholding from any securities otherwise issuable to a Participant
pursuant to the Plan a number of whole shares of such issuable capital stock having a Fair Market Value as of the date of payment, not in excess of the minimum amount of tax required to be withheld by law. The Company or such acquirer may require
the Participant to satisfy any remaining amount of the tax withholding obligations by tendering a cash payment. Each Participant is encouraged to contact his or her personal legal or tax advisors with respect to the benefits provided by the Plan.
Neither the Company nor any of its employees, directors officers or agents are authorized to provide any tax advice to Participants with respect to the benefits provided under the Plan. 

9. Parachute Payments. Any provision of the Plan to the contrary notwithstanding, if any payment or benefit a Participant would receive from the
Company pursuant to the Plan or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the
excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Reduced Amount (defined below). The “Reduced Amount” will be either (l) the largest
portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (2) the entire Payment, whichever amount after taking into account all applicable federal, state and local employment
taxes, income taxes, and the Excise Tax (all computed at the 

  
 6. 

 
highest applicable marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes), results in such Participant’s
receipt, on an after-tax basis, of the greatest amount of the Payment. If a reduction in the Payment is to be made so that the Payment equals the Reduced Amount, (x) the Payment will be paid only to the extent permitted under the Reduced Amount
alternative, and the Participant will have no rights to any additional payments and/or benefits constituting the Payment, and (y) reduction in payments and/or benefits will occur in the following order: (1) reduction of cash payments;
(2) cancellation of accelerated vesting of equity awards other than stock options; (3) cancellation of accelerated vesting of stock options; and (4) reduction of other benefits paid to the Participant. In the event that acceleration
of vesting of equity award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of the Participant’s equity awards. In no event will the Company or any stockholder be liable to
any Participant for any amounts not paid as a result of the operation of this Section 9. The professional firm engaged by the Company for general tax audit purposes as of the day prior to the Closing will perform the foregoing calculations. If
the tax firm so engaged by the Company is serving as accountant or auditor for the acquirer, the Company will appoint a nationally recognized tax firm to make the determinations required hereunder. The Company will bear all expenses with respect to
the determinations by such firm required to be made hereunder. The tax firm engaged to make the determinations hereunder will provide its calculations, together with detailed supporting documentation, to the Company and the Participant within
fifteen (15) days before the Closing (if requested at that time by the Company or the Participant) or such other reasonable time as requested by the Company or a Participant. If the tax firm determines that no Excise Tax is payable with respect
to a Payment, either before or after the application of the Reduced Amount, it will furnish the Company and each Participant with documentation that no Excise Tax is reasonably likely to be imposed with respect to such Payment. Any good faith
determinations of the tax firm made hereunder will be final, binding and conclusive upon the Company and the Participant. 
 10. No Guarantee of
Employment. The Plan is intended to provide a financial incentive to Participants and is not intended to confer any rights to continued employment upon Participants whose employment will remain at-will and subject to termination by either the
Company or Participant at any time, with or without cause or notice. 
 11. No Equity Interest; Status as Creditor. Neither the Plan nor the
allocation of Participation Percentages hereunder creates or conveys any equity or ownership interest in the Company or any rights commonly associated with any such interest, including, but not limited to, the right to vote on any matters put before
the Company’s stockholders. The Participation Percentages do not constitute “securities” of the Company. A Participant’s sole right under the Plan will be as a general unsecured creditor of the Company and the acquiring or
surviving corporation. 
 12. No Assignment or Transfer by Participant. None of the rights, benefits, obligations or duties under the Plan may be
assigned or transferred by any Participant except by will or under the laws of descent and distribution. Any purported assignment or transfer by any such Participant will be void. 

  
 7. 

 13. Termination of the Plan. The Plan and all awards of Participation Percentages hereunder will terminate
and no amounts will be earned and payable hereunder as of and effective on the earliest to occur of (i) any liquidation, dissolution or winding up of the Company, (ii) at such time as all earned payments due under the Plan have been paid,
including any payments in respect of Contingent Consideration, or (iii) the Company’s first underwritten public offering of its Common Stock registered under the Securities Act of 1933, as amended. 

14. Amendment of the Plan. The Plan may be amended by the Administrator (or the Representative, as applicable), provided that no amendment will
adversely affect the rights of a Participant hereunder without the written consent of each Participant. 
 15. Governing Law. The rights and
obligations of a Participant under the Plan will be governed by and interpreted, construed and enforced in accordance with the laws of the State of California without regard to its or any other jurisdiction’s conflicts of laws principles. 

16. Assumption by Acquirer. The Company’s obligations to pay the Corporate Transaction Bonus to Participants hereunder will be deemed to have been
appropriately satisfied if the acquiring or surviving corporation in a Corporate Transaction assumes such obligations and pays the Corporate Transaction Bonus as provided hereunder. 

17. Severability. If any provision of the Plan is held invalid or unenforceable, its invalidity or unenforceability will not affect any other provision
of the Plan, and the Plan will be construed and enforced as if such provision had not been included. 
 18. Entire Agreement. The Plan and the
executed Participation Agreements set forth all of the agreements and understandings between the Company and Participants with respect to the subject matter hereof, and supersedes and terminates all prior agreements and understandings between the
Company and Participants with respect to the subject matter hereof.

FORM OF GENERAL RELEASE 

I understand that I have accepted my designation as a Participant in the Management Retention Bonus Plan (the “Plan”)
of ProteinSimple (the “Company”). In consideration of receiving certain benefits under the Plan, I have agreed to sign this Release. I understand that I am not entitled to benefits under the Plan unless I sign this Release.

 In consideration for the benefits I am receiving under the Plan, I hereby release the Company and its current and former officers,
directors, agents, attorneys, employees, stockholders, parents, subsidiaries, and affiliates and the Representative from any and all claims, liabilities, demands, causes of action, attorneys’ fees, damages, or obligations of every kind and
nature, whether they are now known or unknown, arising at any time prior to and including the date I sign this Release. This general release includes, but is not limited to: all federal and state statutory and common law claims, claims related to my
employment or the termination of my employment or related to breach of contract, tort, wrongful termination, discrimination, wages or benefits, or claims for any form of equity or compensation. 

I understand that I am not releasing any claim that cannot be waived under applicable state or federal law. I am not releasing any rights that
I have to be indemnified (including any right to reimbursement of expenses), arising under applicable law, the certificate of incorporation or by-laws (or similar constituent documents of the Company), any indemnification agreement between me and
the Company, or any directors’ and officers’ liability insurance policy of the Company, for any liabilities arising from my actions within the course and scope of my employment with the Company [or within the course and scope of my
role as a member of the Board of Directors of the Company [for CEO only]]. Nothing in this Release will prevent me from filing, cooperating with, or participating in any proceeding before the Equal Employment Opportunity Commission, or the
Department of Labor, or the California Department of Fair Employment and Housing, except that I hereby acknowledge and agree that I will not recover any monetary benefits in connection with any such proceeding with regard to any claim released in
this Release. Nothing in this Release will prevent me from challenging the validity of my general release in a legal or administrative proceeding. 

In releasing claims unknown to me at present, I am waiving all rights and benefits under Section 1542 of the California Civil Code, and
any law or legal principle of similar effect in any jurisdiction, which states: “A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if
known by him or her must have materially affected his or her settlement with the debtor.”
