 Exhibit 10.5 

DIRECTOR NOMINATION AGREEMENT 

THIS DIRECTOR NOMINATION AGREEMENT (this “Agreement”) is made and entered into as of November 24, 2020, by and among
Maravai LifeSciences Holdings, Inc., a Delaware corporation (the “Company”), Maravai Life Sciences Holdings, LLC, a Delaware limited liability company (“MLSH 1”), Maravai Life Sciences Holdings 2, LLC, a Delaware
limited liability company (“MLSH 2”), GTCR Fund XI/C LP, a Delaware limited partnership, GTCR Fund XI/B LP, a Delaware limited partnership, GTCR Co-Invest XI LP, a Delaware limited
partnership, GTCR Partners XI/A&C LP, a Delaware limited partnership, GTCR Partners XI/B LP, a Delaware limited partnership and GTCR Investment XI LLC, a Delaware limited liability company (collectively, “GTCR”). This Agreement
shall be effective from the date hereof (the “Effective Date”). 
 WHEREAS, as of the date hereof, GTCR beneficially owns a
majority of the equity interests in the Company; 
 WHEREAS, GTCR is contemplating causing the Company to effect an initial public offering
(the “IPO”); 
 WHEREAS, GTCR currently has the authority to appoint all directors of the Company; 

WHEREAS, in consideration of GTCR agreeing to undertake the IPO, the Company has agreed to permit GTCR to designate persons for nomination for
election to the board of directors of the Company (the “Board”) following the Effective Date on the terms and conditions set forth herein; 

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, each of the parties to this Agreement agrees as follows: 
 1. Board Nomination Rights.

 (a) From the Effective Date, GTCR shall have the right, but not the obligation, to nominate to the Board a number of designees equal to
at least: (i) 100% of the Total Number of Directors (as defined below), so long as GTCR Beneficially Owns shares of Class A common stock, par value $0.01 per share (the “Class A common stock”) and the
Company’s Class B common stock, par value $0.01 per share (the “Class B common stock” and together with the Class A common stock, the “Common Stock”) representing at least 40% of
the Original Amount of GTCR, (ii) 40% of the Total Number of Directors, in the event that GTCR Beneficially Owns shares of Common Stock representing at least 30% but less than 40% of the Original Amount of GTCR, (iii) 30% of the Total Number of
Directors, in the event that GTCR Beneficially Owns shares of Common Stock representing at least 20% but less than 30% of the Original Amount of GTCR, (iv) 20% of the Total Number of Directors, in the event that GTCR Beneficially Owns shares of
Common Stock representing at least 10% but less than 20% of the Original Amount of GTCR and (v) one Director, in the event that GTCR Beneficially Owns shares of Common Stock representing at least 5% of the Original Amount of GTCR (such persons,
the “Nominees”). For 

 
purposes of calculating the number of directors that GTCR is entitled to designate pursuant to the immediately preceding sentence, any fractional amounts shall automatically be rounded up to the
nearest whole number (e.g., 11⁄4 Directors shall equate to 2 Directors) and any such calculations shall be made after taking into account any increase in the Total
Number of Directors. 
 (b) In the event that GTCR has nominated less than the total number of designees, GTCR shall be entitled to nominate
pursuant to Section 1(a), GTCR shall have the right, at any time, to nominate such additional designees to which it is entitled, in which case, the Company and the Directors shall take all necessary corporation action, to
the fullest extent permitted by applicable law (including with respect to fiduciary duties under Delaware law), to (x) enable GTCR to nominate and effect the election or appointment of such additional individuals, whether by increasing the size
of the Board, or otherwise and (y) to designate such additional individuals nominated by GTCR to fill such newly created vacancies or to fill any other existing vacancies. 

(c) In addition to the nomination rights set forth in Section 1(a) above, from the Effective Date, for so long as
GTCR Beneficially Owns shares of Common Stock representing at least 5% of the Original Amount of GTCR, GTCR shall have the right, but not the obligation, to designate a person (a “Non-Voting
Observer”) to attend meetings of the Board (including any meetings of any committees thereof) in a non-voting observer capacity. Any such Non-Voting Observer
shall be permitted to attend all meetings of the Board. GTCR shall have the right to remove and replace its Non-Voting Observer at any time and from time to time. The Company shall furnish to any Non-Voting Observer (i) notices of Board meetings no later than, and using the same form of communication as, notice of Board meetings are furnished to directors and (ii) copies of any materials prepared
for meetings of the Board that are furnished to the directors no later than the time such materials are furnished to the directors; provided that failure to deliver notice, or materials, to such Non-Voting
Observer in connection with such Non-Voting Observer’s right to attend and/or review materials with respect to, any meeting of the Board shall not, by itself, impair the validity of any action taken by
such Board at such meeting. Such Non-Voting Observer shall be required to execute or otherwise become subject to any codes of conduct or confidentiality agreements of the Company generally applicable to
directors of the Company or as the Company reasonably requests. Notwithstanding the foregoing, the Company reserves the right to withhold any information and to exclude the Non-Voting Observer from receiving
any materials and/or attending any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel. 

(d) The Company shall pay all reasonable out-of-pocket
expenses incurred by the Nominees and the Non-Voting Observer in connection with the performance of his or her duties as a director or a Non-Voting Observer and in
connection with his or her attendance at any meeting of the Board. 
 (e) “Affiliate” of any person shall mean any other
person controlled by, controlling or under common control with such person; where “control” (including, with its correlative meanings, “controlling,” “controlled by” and “under common
control with”) means possession, directly or indirectly, of power to direct or cause the direction of management or policies (whether through ownership of securities, by contract or otherwise). 

  
 2 

 (f) “Beneficially Own” shall mean that a specified person has or shares the
right, directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, to vote shares of capital stock of the Company. 

(g) “Director” means any member of the Board. 

(h) “Original Amount of GTCR” means the aggregate number of shares of Common Stock held, directly or indirectly, by GTCR on
the date hereof, as such number may be adjusted from time to time for any reorganization, recapitalization, stock dividend, stock split, reverse stock split or other similar changes in the Company’s capitalization. 

(i) “Total Number of Directors” means the total number of Directors comprising the Board. 

(j) No reduction in the number of shares of Common Stock that GTCR Beneficially Owns shall shorten the term of any incumbent director. At the
Effective Date, the Board shall be comprised of 11 members and the initial Nominees shall be Sean Cunningham, Benjamin Daverman, Luke Marker and Constantine Mihas. 

(k) In the event that any Nominee shall cease to serve for any reason, GTCR shall be entitled to designate such person’s successor in
accordance with this Agreement (regardless of GTCR’s beneficial ownership in the Company at the time of such vacancy) and the Board shall promptly fill the vacancy with such successor nominee; it being understood that any such designee shall
serve the remainder of the term of the director whom such designee replaces. 
 (l) If a Nominee is not appointed or elected to the Board
because of such person’s death, disability, disqualification, withdrawal as a nominee or for other reason is unavailable or unable to serve on the Board, GTCR shall be entitled to designate promptly another nominee and the director position for
which the original Nominee was nominated shall not be filled pending such designation. 
 (m) So long as GTCR has the right to nominate
Nominees under Section 1(a) or any such Nominee is serving on the Board, the Company shall use its reasonable best efforts to maintain in effect at all times directors and officers indemnity insurance coverage reasonably satisfactory to GTCR,
and the Company’s Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws (each as may be further amended, supplemented or waived in accordance with its terms) shall at all times provide for indemnification,
exculpation and advancement of expenses to the fullest extent permitted under applicable law. 
 (n) If the size of the Board is expanded,
GTCR shall be entitled to nominate a number of Nominees to fill the newly created vacancies such that the total number of Nominees serving on the Board following such expansion will be equal to that number of Nominees that GTCR would be entitled to
nominate in accordance with Section 1(a) if such expansion occurred immediately prior to any meeting of the stockholders of the Company called with respect to the election of members of the Board, and the Board shall appoint such
Nominees to the Board. 

  
 3 

 (o) At such time as the Company ceases to be a “controlled company” and is
required by applicable law or the NASDAQ Global Select Market (the “Exchange”) listing standards to have a majority of the Board comprised of “independent directors” (subject in each case to any applicable phase-in periods), GTCR’s Nominees shall include a number of persons that qualify as “independent directors” under applicable law and the Exchange listing standards such that, together with any other
“independent directors” then serving on the Board that are not Nominees, the Board is comprised of a majority of “independent directors.” 

(p) At any time that GTCR shall have any nomination rights under Section 1, the Company shall not take any action,
including making or recommending any amendment to the Certificate of Incorporation or the Company’s bylaws that could reasonably be expected to adversely affect GTCR’s rights under this Agreement, in each case without the prior written
consent of GTCR. 
 2. Company Obligations. The Company agrees to use its reasonable best efforts to ensure that prior to the date
that GTCR and its Affiliates cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, (i) each Nominee is included in the Board’s slate of nominees to the
stockholders (the “Board’s Slate”) for each election of directors; and (ii) each Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of
the stockholders of the Company called with respect to the election of members of the Board (each, a “Director Election Proxy Statement”), and at every adjournment or postponement thereof, and on every action or approval by written
consent of the stockholders of the Company or the Board with respect to the election of members of the Board. GTCR will promptly provide reporting to the Company after GTCR ceases to Beneficially Own shares of Common Stock representing at least 5%
of the total voting power of the then outstanding Common Stock, such that Company is informed of when this obligation terminates. The calculation of the number of Nominees that GTCR is entitled to nominate to the Board’s Slate for any election
of directors shall be based on the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by GTCR (“GTCR Voting Control”) immediately prior to the mailing to shareholders of the Director
Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission). Unless GTCR notifies the Company otherwise prior to the mailing to
shareholders of the Director Election Proxy Statement relating to an election of directors, the Nominees for such election shall be presumed to be the same Nominees currently serving on the Board, and no further action shall be required of GTCR for
the Board to include such Nominees on the Board’s Slate; provided, that, in the event GTCR is no longer entitled to nominate the full number of Nominees then serving on the Board, GTCR shall provide advance written notice to the Company, of
which currently servicing Nominee(s) shall be excluded from the Board Slate, and of any other changes to the list of Nominees. If GTCR fails to provide such notice prior to the mailing to shareholders of the Director Election Proxy Statement
relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), a majority of the independent directors then serving on the Board shall determine which of
the Nominees of GTCR then serving on the Board will be included in the Board’s Slate. Furthermore, the Company agrees for so long as the Company qualifies as a “controlled company” under the rules of the Exchange the Company will
elect to be a “controlled company” for purposes of the 

  
 4 

 
Exchange and will disclose in its annual meeting proxy statement that it is a “controlled company” and the basis for that determination. The Company and GTCR acknowledge and agree that,
as of the Effective Date, the Company is a “controlled company.” 
 3. Committees. From and after the Effective Date hereof
until such time as GTCR and its Affiliates cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, GTCR shall have the right to designate a number of members of each
committee of the Board equal to the nearest whole number greater than the product obtained by multiplying (a) the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by GTCR and (b) the number
of positions, including any vacancies, on the applicable committee, provided that any such designee shall be a director and shall be eligible to serve on the applicable committee under applicable law or listing standards of the Exchange, including
any applicable independence requirements (subject in each case to any applicable exceptions, including those for newly public companies and for “controlled companies,” and any applicable phase-in
periods). Any additional members shall be determined by the Board. Nominees designated to serve on a Board committee shall have the right to remain on such committee until the next election of directors, regardless of the level of GTCR Voting
Control following such designation. Unless GTCR notifies the Company otherwise prior to the time the Board takes action to change the composition of a Board committee, and to the extent GTCR has the requisite GTCR Voting Control for GTCR to nominate
a Board committee member at the time the Board takes action to change the composition of any such Board committee, any Nominee currently designated by GTCR to serve on a committee shall be presumed to be
re-designated for such committee. 
 4. Amendment and Waiver. Any provision of this Agreement
may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by the Company and GTCR, or in the case of a waiver, by the party against whom the waiver is to be effective. No failure or
delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. GTCR shall not be obligated to nominate all (or any) of the Nominees it is entitled to nominate pursuant to this
Agreement for any election of directors but the failure to do so shall not constitute a waiver of its rights hereunder with respect to future elections; provided, however, that in the event GTCR fails to nominate all (or any) of the
Nominees it is entitled to nominate pursuant to this Agreement prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement
with the U.S. Securities and Exchange Commission), the Compensation and Governance Committee of the Board shall be entitled to nominate individuals in lieu of such Nominees for inclusion in the Board’s Slate and the applicable Director Election
Proxy Statement with respect to the election for which such failure occurred and GTCR shall be deemed to have waived its rights hereunder with respect to such election. The rights and remedies herein provided shall be cumulative and not exclusive of
any rights or remedies provided by law. 
 5. Benefit of Parties. This Agreement shall be binding upon and shall inure to the benefit
of the parties hereto and their respective permitted successors and assigns. Notwithstanding 

  
 5 

 
the foregoing, the Company may not assign any of its rights or obligations hereunder without the prior written consent of GTCR. Except as otherwise expressly provided in
Section 6, nothing herein contained shall confer or is intended to confer on any third party or entity that is not a party to this Agreement any rights under this Agreement. 

6. Assignment. Upon written notice to the Company, GTCR may assign to any any Affiliate of GTCR (other than a portfolio company) all of
its rights hereunder and, following such assignment, such assignee shall be deemed to be “GTCR” for all purposes hereunder. 

7. Indemnification. 
 (a)
The Company shall defend, indemnify and hold harmless GTCR, its Affiliates, partners, employees, agents, directors, managers, officers and controlling Persons (collectively, the “Indemnified Parties”) from and against any and all actions,
causes of action, suits, claims, liabilities, losses, damages, costs, expenses, or obligations of any kind or nature (whether accrued or fixed, absolute or contingent) in connection therewith (including reasonable attorneys’ fees and expenses)
incurred by the Indemnified Parties before or after the date of this Agreement (each, an “Action”) arising directly or indirectly out of, or in any way relating to, (i) GTCR’s or its Affiliates’ Beneficial Ownership of
Common Stock or other equity securities of the Company or control or ability to influence the Company or any of its subsidiaries (other than any such Actions (x) to the extent such Actions arise out of any breach of this Agreement by an
Indemnified Party or its Affiliates or the breach of any fiduciary or other duty or obligation of such Indemnified Party to its direct or indirect equity holders, creditors or Affiliates or (y) to the extent such Actions are directly caused by
such Person’s willful misconduct), (ii) the business, operations, properties, assets or other rights or liabilities of the Company or any of its subsidiaries or (iii) any services provided prior, on or after the date of this Agreement by
GTCR or its Affiliates to the Company or any of its subsidiaries. The Company shall defend at its own cost and expense in respect of any Action which may be brought against the Company and/or its Affiliates and the Indemnified Parties. The Company
shall defend at its own cost and expense any and all Actions which may be brought in which the Indemnified Parties may be impleaded with others upon any Action by the Indemnified Parties, except that if such damage shall be proven to be the direct
result of gross negligence, bad faith or willful misconduct by any of the Indemnified Parties, then such Indemnified Party shall reimburse the Company for the costs of defense and other costs incurred by the Company in proportion to such Indemnified
Party’s culpability as proven. In the event of the assertion against any Indemnified Party of any Action or the commencement of any Action, the Company shall be entitled to participate in such Action and in the investigation of such Action and,
after written notice from the Company to such Indemnified Party, to assume the investigation or defense of such Action with counsel of the Company’s choice at the Company’s expense; provided, however, that such counsel shall be reasonably
satisfactory to the Indemnified Party. Notwithstanding anything to the contrary contained herein, the Company may retain one firm of counsel to represent all Indemnified Parties in such Action; provided, however, that the Indemnified Party shall
have the right to employ a single firm of separate counsel (and any necessary local counsel) and to participate in the defense or investigation of such Action and the Company shall bear the expense of such separate counsel (and local counsel, if
applicable), if (x) in the opinion of counsel to the Indemnified Party use of counsel of the Company’s choice could reasonably be expected to give rise to a conflict of interest, (y) the Company shall not have

  
 6 

 
employed counsel satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of the assertion of any such Action or (z) the Company shall
authorize the Indemnified Party to employ separate counsel at the Company’s expense. The Company further agrees that with respect to any Indemnified Party who is employed, retained or otherwise associated with, or appointed or nominated by,
GTCR or any of its Affiliates and who acts or serves as a director, officer, manager, fiduciary, employee, consultant, advisor or agent of, for or to the Company or any of its subsidiaries, that the Company or such subsidiaries, as applicable, shall
be primarily liable for all indemnification, reimbursements, advancements or similar payments (the “Indemnity Obligations”) afforded to such Indemnified Party acting in such capacity or capacities on behalf or at the request of the
Company, whether the Indemnity Obligations are created by law, organizational or constituent documents, contract (including this Agreement) or otherwise. The Company hereby agrees that in no event shall the Company or any of its subsidiaries have
any right or claim against GTCR for contribution or have rights of subrogation against GTCR through an Indemnified Party for any payment made by the Company or any of its subsidiaries with respect to any Indemnity Obligation. In addition, the
Company hereby agrees that in the event that GTCR pay or advance an Indemnified Party any expenses with respect to an Indemnity Obligation, the Company will, or will cause its subsidiaries to, as applicable, promptly reimburse GTCR, for such payment
or advance upon request; subject to the receipt by the Company of a written undertaking executed by the Indemnified Party and GTCR, that makes such payment or advance to repay any such amounts if it shall ultimately be determined by a court of
competent jurisdiction that such Indemnified Party was not entitled to be indemnified by the Company. The foregoing right to indemnity shall be in addition to any rights that any Indemnified Party may have at common law or otherwise and shall remain
in full force and effect following the completion or any termination of the engagement. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold it harmless as and to the extent contemplated by
this Section 7, then the Company shall contribute to the amount paid or payable by the Indemnified Party as a result of such Action in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand,
and the Indemnified Party, as the case may be, on the other hand, as well as any other relevant equitable considerations. 
 (b) The Company
hereby acknowledges that the certain of the Indemnified Parties have certain rights to indemnification, advancement of expenses and/or insurance provided by investment funds managed by GTCR and certain of their Affiliates (collectively, the
“Fund Indemnitors”). The Company hereby agrees with respect to any indemnification, hold harmless obligation, expense advancement or reimbursement provision or any other similar obligation whether pursuant to or with respect to this
Agreement, the organizational documents of the Company or any of its subsidiaries or any other agreement, as applicable, (i) that the Company and its subsidiaries are the indemnitor of first resort (i.e., their obligations to the Indemnified
Parties are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for claims, expenses or obligations arising out of the same or similar facts and circumstances suffered by any Indemnified Party are
secondary), (ii) that the Company shall be required to advance the full amount of expenses incurred by any Indemnified Party and shall be liable for the full amount of all expenses, liabilities, obligations, judgments, penalties, fines, and amounts
paid in settlement to the extent legally permitted and as required by the terms of this Agreement, the organizational documents of the Company or any of its subsidiaries or any other agreement, as applicable, without regard to any rights any
Indemnified Party may have against the 

  
 7 

 
Fund Indemnitors, and (iii) that the Company, on behalf of itself and each of its subsidiaries, irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all Actions
against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of any Indemnified Party with respect to any
Action for which any Indemnified Party has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the
rights of recovery of any Indemnified Party against the Company. The Company agrees that the Fund Indemnitors are express third-party beneficiaries of the terms of this Section 7(b). 

8. Headings. Headings are for ease of reference only and shall not form a part of this Agreement. 

9. Governing Law. This Agreement shall be construed in accordance with and governed by the law of the State of Delaware without giving
effect to the principles of conflicts of laws thereof. 
 10. Jurisdiction. Any suit, action or proceeding seeking to enforce any
provision of, or based on any matter arising out of or in connection with, this Agreement may be brought against any of the parties in any federal court located in the State of Delaware or any Delaware state court, and each of the parties hereby
consents to the exclusive jurisdiction of such court (and of the appropriate appellate courts) in any such suit, action or proceeding and waives any objection to venue laid therein. Process in any such suit, action or proceeding may be served on any
party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each of the parties agrees that service of process upon such party at the address referred to in
Section 16, together with written notice of such service to such party, shall be deemed effective service of process upon such party. 

11. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT. 
 12. Entire Agreement. This Agreement constitutes the entire
agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings and negotiations, both written and oral among the parties with respect to the subject matter hereof. 

13. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be deemed an original.
This Agreement shall become effective when each party shall have received a counterpart hereof signed by each of the other parties. An executed copy or counterpart hereof delivered by facsimile shall be deemed an original instrument. 

14. Severability. If any provision of this Agreement or the application thereof to any person or circumstance shall be invalid or
unenforceable to any extent, the remainder of this Agreement and the application of such provisions to other persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

 15. Further Assurances. Each of the parties hereto shall execute and deliver such
further instruments and do such further acts and things as may be required to carry out the intent and purpose of this Agreement. 
 16.

entitled at law or in equity.

 Exhibit 10.8 

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”), Maravai Intermediate Holdings, LLC, a Delaware limited liability company (“Employer”), and Carl W. Hull (“Executive”).
Capitalized terms used but not otherwise defined herein shall have the meanings set forth in Section 4. 
 Maravai
Life Sciences, Inc., a Delaware corporation (“Maravai”), Executive and Maravai Life Sciences Holdings, LLC, a Delaware limited liability company (the “Company”), are parties to a Senior Management Agreement, dated
as of March 18, 2014, as amended from time to time (the “Original Senior Management Agreement”), and concurrently with entering into this Agreement, the Company, Maravai and Executive are amending the Original Senior Management
Agreement (the “Amendment to the Original Senior Management Agreement”) to remove Maravai 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 his separation pursuant to
Section 1(c) (the “Employment Period”). 
 (a) Position and Duties. 

(i) During the Employment Period, Executive shall serve as the Chief Executive Officer of Parent and its Subsidiaries
(including the Employer and any entities created and/or acquired after the date of this Agreement) and shall have the normal duties, responsibilities and authority implied by such position, which shall include defining Parent’s and its
Subsidiaries’ strategy and business plan, selecting and evaluating other executives of Parent and its Subsidiaries, sourcing and completing acquisitions made by Parent and its Subsidiaries and managing the growth and operations of Parent and
its Subsidiaries, and such other activities as are reasonably directed by the board of directors of Parent (the “Board”), including serving on the Board or the board of directors of any Subsidiaries of Parent, subject in each case
to the power of the Board to expand, limit or otherwise alter such duties, responsibilities, positions and authority and to otherwise override actions of officers. Parent further agrees to appoint Executive as Chairman of the Board, with all
requisite rights, duties and obligations of that position without any additional compensation for such service. 
 (ii)
Executive shall report to the Board, and Executive shall devote his best efforts and his full business time and attention to the business and affairs of Parent, Employer and the other Subsidiaries of Parent; provided, that
during the Employment Period, Executive shall be 

 
entitled to (A) serve, with the prior written consent of the Board, on corporate, civic or charitable boards or committees, (B) deliver lectures and fulfill speaking engagements and
(C) manage personal investments, so long as, with respect to clauses (B) and (C), such activities do not interfere substantially with the performance of Executive’s responsibilities to Parent or Employer under this Agreement.
Notwithstanding the foregoing, Parent and Employer consent to Executive’s service on the board of directors of the Persons set forth on Exhibit A attached hereto (the “Permitted Boards”). 

(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 $500,000 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 100% 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 all 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 first anniversary of the date of the Separation an aggregate amount equal to 100% of his Annual Base Salary plus an amount equal to one times the target Annual Bonus
prorated for the number of days worked by Executive for Parent in the calendar year of the Separation, 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 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. 

  
 -2- 

 (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 (A) Executive will be entitled to any earned but unpaid Annual Bonus pursuant to Section 1(b) and (B) during the
two-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 second anniversary of the date of the Separation an aggregate amount equal to 200% of his Annual Base Salary plus an amount equal to two times the target Annual Bonus, 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 his 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 (excluding any compensation earned from Executive’s services on the Permitted Boards). Upon request from time to time, Executive shall furnish Employer with
a true and complete certificate specifying any such compensation earned or received by him 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 

  
 -3- 

 
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 his acceptance of the Release Agreement thereafter, he 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 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 

  
 -4- 

 
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 him during the course of his 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
Executive becomes aware during the Employment Period. Therefore, Executive agrees that he will not disclose to any unauthorized Person or use for his 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
he may then possess or have under his 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 

  
 -5- 

 
copyrightable work prepared in whole or in part by Executive in the course of his 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 his 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 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 his 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 his 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 B 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. 

  
 -6- 

 (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. 
 3. Noncompetition and
Nonsolicitation. Executive acknowledges that in the course of his employment with Employer he will become familiar with Trade Secrets and with other confidential information concerning Parent, Employer and their respective Subsidiaries
and that his services will be of special, unique and extraordinary value to Parent, Employer and their respective Subsidiaries. Therefore, Executive agrees that: 

(a) Noncompetition. Except for Executive’s services on the Permitted Boards, 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. 

  
 -7- 

 (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 his 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 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 he has carefully read this Agreement and consulted with legal counsel of his 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. 

  
 -10- 

 (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 

  
 -11- 

 
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. 

  
 -12- 

 (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)
Deemed Resignations. Except as otherwise determined by the Board or as otherwise agreed to in writing by Executive and Parent, Employer or any of their respective Subsidiaries prior to the termination of Executive’s employment with
Employer, any termination of Executive’s employment shall constitute, as applicable, an automatic resignation of Executive: (i) as an officer of Parent, Employer or any of their respective Subsidiaries; (ii) from the Board; and
(iii) from any other board of directors or board of managers (or similar governing body) of Parent, Employer or any of their respective Subsidiaries and from the board of directors or board of managers (or similar governing body) of any
corporation, limited liability entity, unlimited liability entity or other entity in which Parent, Employer or any of their respective Subsidiaries holds an equity interest and with respect to which board of directors or board of managers (or
similar governing body) Executive serves as the designee or other representative of Parent, Employer or any of their respective Subsidiaries. Executive agrees to take any further actions that Parent, Employer or any of their respective Subsidiaries
reasonably requests to effectuate or document the foregoing. 
 (p) 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. 

(q) 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. 
 (r) 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. 
 (s) 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.
