 Exhibit 10.10 

EXECUTION VERSION 
 EMPLOYMENT
AGREEMENT 
 THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made as of November 24, 2020, by and among
Maravai LifeSciences Holdings, Inc., a Delaware corporation (“Parent”), TriLink Biotechnologies, LLC, a Delaware limited liability company (“Employer”), and Brian Neel (“Executive”). Capitalized
terms used but not otherwise defined herein shall have the meanings set forth in Section 4. 
 Employer, Executive
and Maravai Life Sciences Holdings, LLC, a Delaware limited liability company (the “Company”), are parties to a Senior Management Agreement, dated as of December 27, 2017, as amended from time to time (the “Original
Senior Management Agreement”), and concurrently with entering into this Agreement, the Company, Employer and Executive are amending the Original Senior Management Agreement (the “Amendment to the Original Senior Management
Agreement”) to remove Employer as a party to and to remove the employment-related provisions from the Original Senior Management Agreement, in each case, as provided therein. 

In conjunction with the execution of the Amendment to the Original Senior Management Agreement, Parent, Employer and Executive also mutually
desire to enter into an agreement containing the terms and conditions pursuant to which Employer will continue to employ Executive. This Agreement shall become effective upon the consummation of the initial public offering of Parent (the
“Effective Date”). In the event, such initial public offering does not occur prior to January 25, 2021, this Agreement shall automatically terminate and be null and void and the Original Senior Management Agreement shall remain
in full force and effect. 
 NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows: 
 1.
Employment. Employer agrees to continue to employ Executive, and Executive accepts such continued employment, for the period beginning on the Effective Date and ending upon Executive’s separation pursuant to
Section 1(c) (the “Employment Period”). 
 (a) Position and Duties. 

(i) During the Employment Period, Executive shall serve as the Chief Operating Officer of TriLink Biotechnologies, LLC and
shall have the normal duties, responsibilities and authority implied by such position, which shall include such other activities as are reasonably directed by the Chief Executive Officer of Parent or the board of directors of Parent (the
“Board”), subject in each case to the power of the Chief Executive Officer of Parent to expand, limit or otherwise alter such duties, responsibilities, positions and authority and to otherwise override actions of officers. 

(ii) Executive shall report to the Chief Executive Officer of Parent or such Person’s designee, and Executive shall devote
Executive’s best efforts and Executive’s full business time and attention to the business and affairs of Parent, Employer and the other Subsidiaries of Parent. 

(b) Salary, Bonus and Benefits. Commencing on the Effective Date and continuing until a Separation, Employer will pay Executive a base
salary at a rate of $333,237.49 per annum (the “Annual Base Salary”). The Annual Base Salary shall be reviewed annually by the Board. For each fiscal year of Employer ending during the Employment Period, Executive shall be eligible
for an annual bonus with a target amount equal to 40% of the Annual Base Salary (such amount, the “Annual Bonus”), as 












 
determined by the Board based upon the performance of Executive and the achievement by Parent, Employer and the other Subsidiaries of Parent of financial, operating and other objectives set by
the Board. Each Annual Bonus, if any, shall be paid as soon as administratively feasible after the Board (or a committee thereof) certifies whether the applicable performance targets for the applicable year have been achieved but in no event later
than March 15 following the end of such year. Notwithstanding anything in this Section 1(b) to the contrary, no Annual Bonus, if any, or any portion thereof, shall be payable for any year unless Executive remains
continuously employed by Employer from the Effective Date through the last day of such year. In addition, during the Employment Period, Executive will be entitled to such other benefits as are approved by the Board and made generally available to
other similarly situated members of senior management of Parent and Employer. 
 (c) Separation. The Employment Period will continue
until (x) Executive’s resignation, death or Disability or (y) the Board terminates Executive’s employment with or without Cause. Executive shall have the right to terminate Executive’s employment with Employer without Good
Reason and for any other reason, or no reason at all, upon thirty (30) days’ advance written notice to Employer; provided, however, that if Executive has provided notice to Employer of Executive’s termination of employment, Employer
may determine, in its sole discretion, that such termination shall be effective on any date prior to the effective date of termination provided in such notice (and, if such earlier date is so required, then it shall not change the basis for
Executive’s termination of employment nor be construed or interpreted as a termination of employment by the Board without Cause) and any requirement to continue salary or benefits shall cease as of such earlier date. 

(i) Payment Upon Separation. If Executive’s employment is terminated by resignation of Executive with Good Reason
pursuant to clause (x) above or by the Board without Cause pursuant to clause (y) above, then (A) Executive will be entitled to any earned but unpaid Annual Bonus pursuant to Section 1(b) and (B) during
the one-year period commencing on the date of termination (the “Severance Period”), (I) Employer shall pay to Executive during the period beginning on the date of the Separation and ending on
the nine month anniversary of the date of the Separation an aggregate amount equal to 75% of Executive’s Annual Base Salary payable in equal installments on Employer’s regular salary payment dates as in effect on the date of the
Separation, and (II) if Executive is eligible to and does elect continuation coverage under Employer’s health benefit plan pursuant to the provisions of Section 4980B of the Code, then Employer shall reimburse to Executive the
premiums paid for such coverage by Executive during the portion of the Severance Period of which Executive is eligible for and elects such continuation coverage under Employer’s health benefit plan, provided that such reimbursements shall not
be made in the event an excise tax under Section 4980D of the Code would be imposed on Employer as a result. 
 (ii)
Payment Upon Separation following a Change in Control. If, during the period commencing upon a Change in Control (as defined below) and ending on the twelve month anniversary of such Change in Control, Executive’s employment is
terminated by resignation of Executive with Good Reason or by Parent or Employer (or their respective successors) without Cause, then during the one-year period commencing on the date of termination (the
“CIC Severance Period”), (I) Employer shall pay to Executive during the period beginning on the date of the Separation and ending on the first anniversary of the date of the Separation an aggregate amount equal to 100% of
Executive’s Annual Base Salary, subject to Section 1(d), payable in equal installments on Employer’s regular salary payment dates as in effect on the date of the Separation, and (II) if Executive is
eligible to and does elect continuation coverage under Employer’s health benefit plan pursuant to the provisions of Section 4980B of the Code, then Employer shall reimburse to Executive the premiums paid for such coverage by Executive
during the portion of the CIC Severance Period of which Executive is eligible for and elects such continuation coverage under Employer’s health benefit plan, provided that such reimbursements shall not be made in the event an excise tax under
Section 4980D of the Code would be imposed on Employer as a result.

 (iii) Release Agreement. Notwithstanding anything herein to the
contrary, (A) Executive shall not be entitled to receive any payments or other benefits pursuant to this Section 1(c) unless Executive has timely executed and delivered to Employer a general release and separation
agreement in form prepared by Employer (a “Release Agreement”) (and such Release Agreement shall become in full force and effect and not been timely revoked as may be permitted by its terms), which Release Agreement shall be
delivered by Executive within fifteen (15) calendar days after Executive’s Separation and (B) Executive shall be entitled to receive such payments only so long as Executive has not breached any of the provisions of such Release
Agreement or Section 2 or Section 3. The amounts payable pursuant to this Section 1(c) shall be reduced by the amount of any compensation earned or received by Executive
during the Severance Period or CIC Severance Period, as applicable, in connection with the performance of any services by Executive. Upon request from time to time, Executive shall furnish Employer with a true and complete certificate specifying any
such compensation earned or received by Executive while receiving any payments from Employer pursuant to this Section 1(c). Executive shall not be entitled to any further payments from Parent, Employer or their Affiliates,
nor shall they have any further liability to Executive, except as expressly set forth in this Section 1(c). 
 (d)
Code Section 409A. The intent of the parties is that payments and benefits under this Agreement comply with or otherwise be exempt from Internal Revenue Code Section 409A and the regulations and guidance promulgated
thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be either exempt from or in compliance therewith. In no event whatsoever
shall Parent or Employer be liable for any additional tax, interest or penalty that may be imposed on the Executive by Code Section 409A or damages for failing to comply with Code Section 409A. Notwithstanding any other payment schedule
provided herein to the contrary, if the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then any payment under this
Section 1 that is considered deferred compensation under Code Section 409A payable on account of a “separation from service” shall not be made until the date which is the earlier of (i) the expiration of
the six (6)-month period measured from the date of such “separation from service” of Executive, and (ii) the date of Executive’s death (the “Delay Period”) to the extent required under Code Section 409A.
Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 1(d) shall be paid to the Executive in a lump sum, and all remaining payments due under this Agreement shall be paid or provided in
accordance with the normal payment dates specified for them herein. A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or
following a termination of employment unless such termination is also a “separation from service” from Parent and Employer within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references
to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Notwithstanding anything to the contrary in this Agreement, to the extent that any payments of “nonqualified
deferred compensation” (within the meaning of Code Section 409A) due under this Agreement as a result of Executive’s termination of employment are subject to Executive’s execution and delivery of a Release Agreement, (A) if
Executive fails to execute the Release Agreement on or prior to the Release Expiration Date (as defined below) or timely revokes Executive’s acceptance of the Release Agreement thereafter, Executive shall not be entitled to any payments or
benefits otherwise conditioned on the Release Agreement, and (B) in any case where the date of termination of employment and the Release Expiration Date fall in two separate taxable years, any payments required to be made to Executive that are
conditioned on the Release Agreement and are treated as “nonqualified deferred compensation” (within the meaning of Code Section 409A) shall be made in the later taxable year. For purposes of this

Section 1(d) “Release Expiration Date” shall mean the date that is 21 days following 

  
 -3- 













 
the date of Executive’s termination of employment, or, in the event that Executive’s termination of employment is “in connection with an exit incentive or other employment
termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), the date that is 45 days following the date of Executive’s termination of employment. To the extent that any payments of nonqualified
deferred compensation (within the meaning of Code Section 409A) due under this Agreement as a result of Executive’s termination of employment are delayed pursuant to this
 Section 1(d), such amounts shall be
paid in a lump sum on the first payroll date following the date that Executive executes and does not revoke the Release Agreement (and the applicable revocation period has expired) or, in the case of any payments subject to clause (B) of this
Section 1(d), on the first payroll period to occur in the subsequent taxable year, if later. To the extent, if any, that the aggregate amount of the installments of the severance payment that would otherwise be paid
pursuant to Section 1(c) after March 15 of the calendar year following the calendar year in which the Separation occurs (the “Applicable March 15”) exceeds the maximum exemption
amount under Treasury Regulation Section 1.409A-1(b)(9)(iii)(A), then such excess shall be paid to Executive in a lump sum on the Applicable March 15 (or the first business day preceding the
Applicable March 15 if the Applicable March 15 is not a business day) and the installments of the severance payment payable after the Applicable March 15 shall be reduced by such excess (beginning with the installment first payable
after the Applicable March 15 and continuing with the next succeeding installment until the aggregate reduction equals such excess). For purposes of Code Section 409A, the Executive’s right to receive any installment payment pursuant
to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Notwithstanding any other provision to the contrary, in no event shall any payment under this Agreement that constitutes “deferred
compensation” for purposes of Code Section 409A be subject to offset by any other amount unless otherwise permitted by Code Section 409A. 

(e) Certain Excise Taxes. Notwithstanding anything to the contrary in this Agreement, if Executive is a “disqualified
individual” (as defined in Section 280G(c) of the Code), and the separation payments and benefits provided for in this Agreement, together with any other payments and benefits which such Executive has the right to receive from Parent or
any of its Affiliates, would constitute a “parachute payment” (as defined in
 Section 280G(b)(2) of the Code), then the payments provided for in this Agreement shall be either (a) reduced (but not below zero) so that the
present value of such total amounts and benefits received by Executive from the Parent and its Affiliates will be one dollar less than three times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code) and so
that no portion of such amounts and benefits received by Executive shall be subject to the excise tax imposed by Section 4999 of the Code or (b) paid in full, whichever produces the better net
after-tax position to Executive (taking into account any applicable excise tax under Section 4999 of the Code and any other applicable taxes). The determination as to whether any such reduction in the
amount of the payments provided hereunder is necessary shall be made by Parent in good faith. If a reduced payment is made and through error or otherwise that payment, when aggregated with other payments and benefits from Parent (or its Affiliates)
used in determining if a “parachute payment” exists, exceeds one dollar less than three times Executive’s base amount, then Executive shall immediately repay such excess to Parent (or its Affiliates) upon notification that an
overpayment has been made. Nothing in this Section 1(e) shall require Parent or Employer to be responsible for, or have any liability or obligation with respect to, Executive’s excise tax liabilities under
Section 4999 of the Code. 
 2. Confidential Information. 

(a) Obligation to Maintain Confidentiality. Executive acknowledges that the information, observations and data (including trade secrets)
obtained by Executive during the course of Executive’s employment with Employer prior to and after the Effective Date concerning the business or affairs of Parent, Employer and their respective Subsidiaries and Affiliates (“Confidential
Information”) are the property of Parent, Employer or such Subsidiaries and Affiliates, including information concerning acquisition opportunities in or reasonably related to Parent’s and Employer’s business or industry of which


  
 -4- 













 
Executive becomes aware during the Employment Period. Therefore, Executive agrees that Executive will not disclose to any unauthorized Person or use for Executive’s own account any
Confidential Information without the Board’s written consent, unless and to the extent that the Confidential Information, (i) becomes generally known to and available for use by the public other than as a result of Executive’s acts or
omissions to act or (ii) is required to be disclosed pursuant to any applicable law or court order. Executive shall deliver to Employer at a Separation, or at any other time Employer may request, all memoranda, notes, plans, records, reports,
computer tapes, printouts and software and other documents and data (and copies thereof) relating to the Confidential Information, Work Product (as defined below) or the business of Parent, Employer and their respective Subsidiaries and Affiliates
(including all acquisition prospects, lists and contact information) which Executive may then possess or have under Executive’s control. 

(b) Protection of Trade Secrets. Executive acknowledges and agrees with Employer that Executive’s services to Employer and to
Parent and their respective Subsidiaries and Affiliates require the use of Confidential Information and trade secret information (including any formula, pattern, compilation, program, device, method, technique or process) that Employer, Parent or
their respective Subsidiaries and Affiliates have made reasonable efforts to keep confidential and that derives independent economic value, actual or potential, from not being generally known to the public or to other persons who can obtain economic
value from its disclosure or use (“Trade Secrets”). Executive further acknowledges and agrees that Employer, Parent and such Subsidiaries and Affiliates would be irreparably harmed if Executive were to provide similar services
requiring the use of such Trade Secrets. 
 (c) Ownership of Property. Executive acknowledges that all discoveries, concepts, ideas,
inventions, innovations, improvements, developments, methods, processes, programs, designs, analyses, drawings, reports, patent applications, copyrightable work and mask work (whether or not including any confidential information) and all
registrations or applications related thereto, all other proprietary information and all similar or related information (whether or not patentable) that relate to Parent, Employer or any of their respective Subsidiaries or Affiliates engaging in
Parent Business or an anticipated business in which Parent, Employer or any of their respective Subsidiaries or Affiliates have a bona fide interest or expectancy relating to the acquisition of a business by Parent, Employer or any of their
respective Subsidiaries, research and development, or existing or future products or services and that are conceived, developed, contributed to, made, or reduced to practice by Executive (either solely or jointly with others) while employed by
Parent, Employer or any of their respective Subsidiaries or Affiliates (including any of the foregoing that constitutes any proprietary information or records) (“Work Product”) belong to Parent, Employer or such Subsidiary or
Affiliate, and Executive hereby assigns, and agrees to assign, all of the above Work Product to Parent, Employer or to such Subsidiary or Affiliate. Any copyrightable work prepared in whole or in part by Executive in the course of
Executive’s work for any of the foregoing entities shall be deemed a “work made for hire” under the copyright laws, and Parent, Employer or such Subsidiary or Affiliate shall own all rights therein. To the extent that any such
copyrightable work is not a “work made for hire,” Executive hereby assigns and agrees to assign to Parent, Employer or such Subsidiary or Affiliate all right, title, and interest, including without limitation, copyright in and to such
copyrightable work. Executive shall promptly disclose such Work Product and copyrightable work to the Board and perform all actions reasonably requested by the Board (whether during or after the Employment Period), to establish and confirm
Parent’s, Employer’s or such Subsidiary’s or Affiliate’s ownership (including assignments, consents, powers of attorney, and other instruments); provided, that Parent shall reimburse Executive for Executive’s
reasonable and documented out-of-pocket expenses in connection therewith. 

(d) Third Party Information. Executive understands that Parent, Employer and their respective Subsidiaries and Affiliates will receive
from third parties confidential or proprietary information (“Third Party Information”) subject to a duty on Parent’s, Employer’s and their respective Subsidiaries and Affiliates’ part to maintain the confidentiality
of such information and to use it only for certain limited 

  
 -5- 













 
purposes. During the Employment Period and thereafter, and without in any way limiting the provisions of Section 2(a), Executive will hold Third Party Information in the
strictest confidence and will not disclose to anyone (other than personnel and consultants of Parent, Employer or their respective Subsidiaries and Affiliates who need to know such information in connection with their work for Parent, Employer or
their respective Subsidiaries and Affiliates) or use, except in connection with Executive’s work for Parent, Employer or their respective Subsidiaries and Affiliates, Third Party Information unless expressly authorized by a member of the
Board (other than Executive) in writing. 
 (e) Use of Information of Prior Employers. During the Employment Period, Executive will
not improperly use or disclose any confidential information or trade secrets, if any, of any former employers or any other Person to whom Executive has an obligation of confidentiality, and will not bring onto the premises of Parent, Employer or any
of their respective Subsidiaries or Affiliates any unpublished documents or any property belonging to any former employer or any other Person to whom Executive has an obligation of confidentiality unless consented to in writing by the former
employer or Person. Executive will use in the performance of Executive’s duties only information which is (i) generally known and used by persons with training and experience comparable to Executive’s and which is
(x) common knowledge in the industry or (y) is otherwise legally in the public domain, (ii) otherwise provided or developed by Parent, Employer or any of their respective Subsidiaries or Affiliates or (iii) in the case of
materials, property or information belonging to any former employer or other Person to whom Executive has an obligation of confidentiality, approved for such use in writing by such former employer or Person. In furtherance of the foregoing,
concurrently with the execution of this Agreement, Executive shall execute and deliver to Employer a certificate in the form of Exhibit A attached hereto. 

(f) Continuation of Terms. Notwithstanding anything in this Agreement to the contrary, the parties hereto expressly acknowledge and
agree that the terms, conditions, obligations and covenants set forth in this Section 2 are a continuation without interruption, lapse, reprieve, gap or modification of any kind of the terms, conditions, obligations and
covenants set forth in Section 8 of the Original Senior Management Agreement. 
 (g) Whistleblower Protections. Notwithstanding
anything to the contrary contained herein, no provision of this Agreement will be interpreted so as to impede Executive (or any other individual) from reporting possible violations of federal law or regulation to any governmental agency or entity,
including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any Inspector General of any United States federal agency, or making other disclosures under the whistleblower provisions of federal
law or regulation. Executive does not need the prior authorization of Parent or Employer to make any such reports or disclosures, and Executive will not be required to notify Parent or Employer that such reports or disclosures have been made. 

(h) Trade Secrets. An individual will not be held criminally or civilly liable under any federal or state trade secret law for the
disclosure of a trade secret that (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and (B) solely for the purpose of reporting or investigating a
suspected violation of law; or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Nothing in this Agreement is intended to conflict with 18 U.S.C. § 1833(b) or
create liability for disclosures of trade secrets that are expressly allowed by 18 U.S.C. § 1833(b). Accordingly, the parties to this Agreement have the right to disclose in confidence trade secrets to federal, state, and local government
officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of law. The parties also have the right to disclose trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing is
made under seal and protected from public disclosure. 

  
 -6- 













 3. Noncompetition and Nonsolicitation. Executive acknowledges that in the course of
Executive’s employment with Employer, Executive will become familiar with Trade Secrets and with other confidential information concerning Parent, Employer and their respective Subsidiaries and that Executive’s services will be of special,
unique and extraordinary value to Parent, Employer and their respective Subsidiaries. Therefore, Executive agrees that: 
 (a)
Noncompetition. During the Employment Period, Executive shall not engage in any business activity other than for the benefit of the Parent, Employer or any of their respective Subsidiaries. 

(b) Nonsolicitation. During the Employment Period, other than in good faith in the best interests of the Parent, Employer or any of
their respective Subsidiaries, Executive shall not directly or indirectly through another entity (i) induce or attempt to induce any employee of Parent, Employer or any of their respective Subsidiaries to leave the employ of Parent, Employer or
such Subsidiary, or in any way interfere with the relationship between Parent, Employer or any of their respective Subsidiaries and any employee thereof, (ii) hire any employee of Parent, Employer or any of their respective Subsidiaries or,
hire any former employee of Parent, Employer or any of their respective Subsidiaries within one year after such person ceased to be an employee of Parent, Employer or any of their respective Subsidiaries or (iii) induce or attempt to induce any
customer, supplier, licensee or other business relation of Parent, Employer or any of their respective Subsidiaries to cease doing business with Parent, Employer or such Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and Parent, Employer or any such Subsidiary. 
 (c) Enforcement. If, at the time of
enforcement of Section 2 or this Section 3, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum duration,
scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum duration, scope and area
permitted by law. Because Executive’s services are unique and because Executive has access to confidential information, the parties hereto agree that money damages would be an inadequate remedy for any breach of this Agreement. Therefore, in
the event of a breach or threatened breach of this Agreement, any party and/or their respective successors or assigns may, in addition to other rights and remedies existing in their favor, subject to Section 6(g), apply to
any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof. 

(d) Additional Acknowledgments. Executive acknowledges that the provisions of this Section 3 are in
consideration of: (i) employment with Employer and (ii) additional good and valuable consideration as set forth in this Agreement. In addition, Executive agrees and acknowledges that the restrictions contained in
Section 2 and this Section 3 do not preclude Executive from earning a livelihood, nor do they unreasonably impose limitations on Executive’s ability to earn a living. In addition, Executive
acknowledges (A) that the business of Parent, Employer and their respective Subsidiaries will be conducted throughout the United States and other jurisdictions where Parent, Employer or any of their respective Subsidiaries conduct business
during the Employment Period, (B) notwithstanding the state of organization or principal office of Parent, Employer or any of their respective Subsidiaries, or any of their respective executives or employees (including Executive), it is
expected that Parent, Employer and their respective Subsidiaries will have business activities and have valuable business relationships within its industry throughout the United States and other jurisdictions where Parent, Employer or any of their
respective Subsidiaries conduct business during the Employment Period, and (C) as part of Executive’s responsibilities, Executive will be traveling throughout the United States and other jurisdictions where Parent, Employer or any of their
respective Subsidiaries conduct business during the Employment Period in furtherance of Employer’s business and its relationships. Executive agrees and acknowledges that the 

  
 -7- 













 
potential harm to Parent, Employer and their respective Subsidiaries of the non-enforcement of any provision of Section 2 or this
Section 3 outweighs any potential harm to Executive of its enforcement by injunction or otherwise. The covenants contained in each of Sections 2(a), 2(b), 2(c), 2(d), 2(e),
 3(a)
and 3(b) may be enforced independently and without any one or more of such sections limiting the provisions of any one or more of the other of such sections. Executive acknowledges that Executive has carefully read this Agreement and
consulted with legal counsel of Executive’s choosing regarding its contents, has given careful consideration to the restraints imposed upon Executive by this Agreement and is in full accord as to their necessity for the reasonable and proper
protection of confidential and proprietary information of Parent, Employer and their respective Subsidiaries now existing or to be developed in the future. Executive expressly acknowledges and agrees that each and every restraint imposed by this
Agreement is reasonable with respect to subject matter, time period and geographical area.

6. General Provisions. 

(a) Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any
other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 

(b) Entire Agreement. This Agreement, those documents expressly referred to herein, embody the complete agreement and understanding
among the parties hereto and supersede and preempt any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way, including the Original Senior
Management Agreement. 
 (c) Descriptive Headings; Interpretation; No Strict Construction. The descriptive headings of this Agreement
are inserted for convenience only and do not constitute a substantive part of this Agreement. Whenever required by the context, any pronoun used in this Agreement shall include the corresponding masculine, feminine, or neuter forms, and the singular
form of nouns, pronouns, and verbs shall include the plural and vice versa. The use of the word “including” in this Agreement shall be by way of example rather than by limitation. Reference to any agreement, document, or instrument means
such agreement, document, or instrument as amended or otherwise modified from time to time in accordance with the terms thereof, and, if applicable, hereof. The use of the words “or,” “either,” and “any” shall not be
exclusive. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the
parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement.

 (d) Counterparts. This Agreement may be executed in multiple counterparts with the
same effect as if all signing parties had signed the same document. All counterparts shall be construed together and constitute the same instrument. 

(e) Successors and Assigns. Except as otherwise provided herein, this Agreement shall bind and inure to the benefit of and be
enforceable by Executive, Parent, Employer, and their respective successors and assigns; provided, that the rights and obligations of Executive under this Agreement shall not be assigned or delegated. In the event of Executive’s death
prior to completion by Parent of all payments due under this Agreement, Parent shall make all such payments to Executive’s beneficiary or to Executive’s estate as appropriate. 

(f) Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of California, without
giving effect to any choice of law or conflict of law rules or provisions (whether of the State of California or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of California. 

(g) Dispute Resolution. Any controversy, dispute or claim arising out of or relating to this Agreement (a “Covered
Claim”) shall be resolved by binding arbitration to be held in San Diego, California, and shall be administered by JAMS in accordance with the Employment Arbitration Rules & Procedures of JAMS then in effect and subject to JAMS
Policy on Employment Arbitration Minimum Standards. Each party shall pay their own costs and expenses (including attorneys’ fees and other charges of counsel) incurred in resolving any such Covered Claim; provided, that in the event
litigation is required to compel arbitration or to enforce an arbitration award or judgment pursuant to this Agreement, the non-prevailing party in such litigation shall reimburse the costs and expenses
(including attorney’s fees and other charges of counsel) of the prevailing party. Judgment upon the award rendered by the arbitrator(s) may be entered into any court having jurisdiction thereof. The parties hereto agree that any action to
compel arbitration pursuant to this Agreement shall be brought in the appropriate California state court, and in connection with such action to compel, the laws of California shall control. 

(h) Executive’s Cooperation. During the Employment Period and thereafter, Executive shall cooperate with Parent, Employer and
their respective Subsidiaries and Affiliates in any disputes with third parties, internal investigation or administrative, regulatory or judicial proceeding as reasonably requested by Parent (including Executive being available to Parent upon
reasonable notice for interviews and factual investigations, appearing at Parent’s request to give testimony without requiring service of a subpoena or other legal process, volunteering to Parent all pertinent information and turning over to
Parent all relevant documents which are or may come into Executive’s possession, all at times and on schedules that are reasonably consistent with Executive’s other permitted activities and commitments). In the event Parent requires
Executive’s cooperation in accordance with this paragraph after the Employment Period, Parent shall reimburse Executive for Executive’s reasonable time at a rate of $100 per hour and reasonable travel expenses (including lodging and meals,
upon submission of receipts). 
 (i) Remedies. Each of the parties to this Agreement shall have all rights and remedies set forth in
this Agreement and all rights and remedies which such Person has been granted at any time under any other agreement or contract and all of the rights which such Person has under any law. Each of the parties to this Agreement will be entitled to
enforce its rights under this Agreement specifically, to recover damages and costs caused by any breach of any provision of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party and/or their respective successors and assigns may, in addition to other rights and remedies existing in their favor, but subject to
Section 6(g), apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions of this Agreement.

 (j) Amendment and Waiver. The provisions of this Agreement may be amended and waived
only with the prior written consent of Parent, Employer and Executive. No failure by any party to insist upon the strict performance of any covenant, duty, agreement, or condition of this Agreement or to exercise any right or remedy consequent upon
a breach thereof shall constitute a waiver of any such breach or any other covenant, duty, agreement, or condition. The waiver by any party of a breach of any covenant, duty, agreement, or condition of this Agreement of any other party shall not
operate or be construed as a waiver of any subsequent breach of that provision or any other provision hereof. 
 (k) Insurance.
Parent or Employer, at its discretion, may apply for and procure in its own name and for its own benefit life and/or disability insurance on Executive in any amount or amounts considered available. Executive agrees to cooperate in any medical or
other examination, supply any information, and to execute and deliver any applications or other instruments in writing as may be reasonably necessary to obtain and constitute such insurance. 

(l) Business Days. If any time period for giving notice or taking action hereunder expires on a day which is a Saturday, Sunday or
holiday in the state in which Parent’s chief executive office is located, the time period shall be automatically extended to the business day immediately following such Saturday, Sunday or holiday. 

(m) Tax Withholding. Parent, Employer and their respective Subsidiaries shall be entitled to deduct or withhold from any amounts owing
from Parent, Employer or any of their respective Subsidiaries to Executive (including withholding shares or other equity securities in the case of issuances of equity by Parent, Employer or any of their respective Subsidiaries) any federal, state,
local or foreign withholding taxes, excise taxes, or employment taxes (“Taxes”) imposed with respect to Executive’s compensation or other payments from Parent, Employer or any of their respective Subsidiaries or
Executive’s ownership interest in Parent, including wages, bonuses, distributions, the receipt or exercise of equity options and/or the receipt or vesting of restricted equity. In the event any such deductions or withholdings are not made,
Executive shall indemnify Parent, Employer and each of their respective Subsidiaries for any amounts paid with respect to any such Taxes, together with any interest, penalties and related expenses thereto; provided, that, Executive shall not
be obligated to indemnify Parent pursuant to this Section 6(m) for such interest, penalties or related expenses which are directly caused by the failure of Parent to take necessary action with respect to such deductions and
withholdings as it is required by law to take. 
 (n) Termination. This Agreement (except for the provisions of Sections 1(a)
and 1(b)) shall survive a Separation and shall remain in full force and effect after such Separation. 
 (o) Electronic
Delivery. This Agreement, the agreements referred to herein, and each other agreement or instrument entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent signed
and delivered by means of a photographic, portable document format (.pdf), or similar reproduction of such signed writing using an electronic mail shall be treated in all manner and respects as an original agreement or instrument and shall be
considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties hereto. No party hereto or to any such agreement or instrument shall raise the use of electronic mail to deliver a signature or the fact that
any signature or agreement or instrument was transmitted or communicated through the use of electronic mail as a defense to the formation or enforceability of a contract and each such party forever waives any such defense.

 (p) No Third-Party Beneficiaries. Except as expressly provided herein (including the
last sentence of Section 6(e)), no term or provision of this Agreement is intended to be, or shall be, for the benefit of any Person not a party hereto, and no such other Person shall have any right or cause of action
hereunder. Notwithstanding the foregoing, any Subsidiary or Parent or Employer that is not a signatory to this Agreement shall be a third party beneficiary of Executive’s obligations under Sections 2, 3, 6(g), 6(h)
and 6(o) and shall be entitled to enforce such obligations as if a party hereto. 
 (q) Directors’ and Officers’
Insurance. Each of Parent and Employer agree that it shall obtain and maintain in full force and effect during the term of Executive’s employment hereunder directors’ and officers’ insurance policies in amounts and with coverages
customary for entities of the size and with the type of business of Parent and Employer, respectively. 
 (r) Clawback. To the extent
required by applicable law or any applicable securities exchange listing standards, or as otherwise determined by the Board (or a committee thereof), amounts paid or payable under this Agreement shall be subject to the provisions of any applicable
clawback policies or procedures adopted by Parent, Employer or any of their Affiliates or Subsidiaries, which clawback policies or procedures may provide for forfeiture and/or recoupment of amounts paid or payable under this Agreement.
Notwithstanding any provision of this Agreement to the contrary, each of Parent, Employer or any of their Affiliates or Subsidiaries reserves the right, without the consent of Executive, to adopt any such clawback policies and procedures, including
such policies and procedures applicable to this Agreement with retroactive effect; provided, however, that such clawback policies and procedures shall not apply to compensation paid prior to the Employment Period.
