THIS EMPLOYMENT AGREEMENT (this “Agreement”) is signed as of September 29, 2022, and effective as of September 30, 2022 (the “Effective Date”), by and among Maravai LifeSciences Holdings, Inc., a Delaware corporation (“Parent”), Maravai Intermediate Holdings, LLC, a Delaware limited liability company (“Employer”), and William “Trey” Martin, III (“Executive”). Capitalized terms used but not otherwise defined shall have the meanings set forth in Section 4.

NOW, THEREFORE, in consideration of the mutual covenants contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are acknowledged, the parties to this Agreement agree as follows:

1.Employment.    Employer agrees to employ Executive, and Executive accepts such employment, for the period beginning on the Effective Date and ending upon his separation pursuant to Section 1(e) (the “Employment Period”).

(a)Position and Duties.

(i)During the Employment Period, Executive shall serve as 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”), 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.

(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.

(iii)Executive’s primary work location shall be Employer’s corporate headquarters in San Diego, California, and Employee shall be allowed to work remotely from time to time, but is expected to be in San Diego no less than approximately two weeks of every month in the first year of the Employment Period.

(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 $750,000 per annum (the “Annual Base Salary”). The Annual Base Salary shall be reviewed annually by the Board or its Compensation Committee. 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 $937,500 for 2022 and 125% of the Annual Base Salary in subsequent years (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 performance targets for the applicable year have been achieved but in no event later than March 15 following the end of such year. Subject to Section 1(d), 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)Sign-on Bonus. Employer will pay Executive a cash sign-on bonus of $470,000 (the “Sign-on Bonus”) as soon as administratively practicable following the Effective Date, in accordance with Employer’s regularly-schedule payroll practices. If Executive’s employment is terminated due to Executive’s resignation without Good Reason before the one-year anniversary of the Effective Date, Executive shall repay Employer 100% of this Sign-on Bonus. If Executive is required to repay the Sign-on Bonus and the law of the state of Executive’s primary employment allows a deduction from final pay, Executive authorizes a deduction from Executive’s final paycheck for any unearned Sign-on Bonus to the fullest extent allowed by law. If there is any balance owing or if state law does not allow a deduction from Executive’ final pay, Executive agrees to repay the unearned Sign-on Bonus within 30 days of Executive’s final day of employment.

(d)Equity Awards. Following the Effective Date, the Board (or a committee thereof) will grant Executive the following equity awards pursuant to, and subject to the terms and conditions of, Parent’s 2020 Omnibus Incentive Plan and associated award agreements: (i) restricted stock units that vest 50% annually over a two-year period with an approximate grant date fair value of $2,500,000 (with the final number of restricted stock units granted determined using the 20 trading day volume-weighted average price of Parent’s Class A common stock on the grant date (the “Grant Calculation Methodology”)), (ii) non-qualified stock options that vest over a four year period with an approximate grant date fair value of $4,750,000 (with the final number of shares subject to such non-qualified stock options determined using the Grant Calculation Methodology), (iii) additional restricted stock units that vest over a three year period with an approximate grant date fair value of $4,750,000 (with the final number of restricted stock units granted determined using the Grant Calculation Methodology), and (iv) performance stock units with an approximate grant date fair value of $5,000,000 (with the final number of performance stock units granted determined using the Grant Calculation Methodology) that vest 50% in the event the 60-trading day volume-weighted average stock price of Parent’s Class A common stock equals or exceeds $60 (as adjusted for stock splits, stock dividends and other similar events) on the third anniversary of the grant date and 50% in the event the 60-day volume-weighted average stock price of Parent’s Class A common stock equals or exceeds $100 (as adjusted for stock splits, stock dividends and other similar events) on the third anniversary of the grant date. In the event of a Change in Control prior to the third anniversary of the grant date of the performance stock units, the performance stock units will convert to time-based restricted stock units that vest 100% on the third anniversary of the grant date. The award agreements for stock options and restricted stock units subject to time-based vesting, as described in clauses (i) through (iii) above, will provide for accelerated vesting upon an involuntary termination without Cause or a voluntary resignation for Good Reason within the one year period following a Change in Control.

(e)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 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 before 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.

(iv)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, in addition to any accrued but unpaid Annual Base Salary and benefits (the “Accrued Amounts”), (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 Separation and ending on the 12 month anniversary of the date of the Separation (the “Severance Period”), (I) Employer shall pay to Executive 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(e), payable in substantially 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.

(v)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 12 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, in addition to the Accrued Amounts, (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 Separation and ending on the second anniversary of the date of Separation (the “CIC Severance Period”), (I) Employer shall pay to Executive 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(f), payable in substantially 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.

(vi)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(e) (other than the Accrued Amounts) 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 on or prior to the Release Expiration Date (as defined below) 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.

(f)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 any regulations and guidance (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 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-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(f) 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 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(f) “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(f), 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(f), 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(e) 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. 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.

(a)Certain Excise Taxes. 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(f) 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 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 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 A attached.

(f)Whistleblower Protections. 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.

(g)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:

(b)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.

(c)Nonsolicitation. During the Employment Period and for one year thereafter, 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 or (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.

(d)Enforcement. If, at the time of enforcement of Section 2 or this Section 3, a court holds that the restrictions stated are unreasonable under circumstances then existing, the parties 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 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 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.

(e)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.

(h)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.

(i)Entire Agreement. This Agreement, those documents expressly referred to, including Exhibit “A” and the Indemnification Agreement that will be entered into between Executive and Parent similar to the agreements with other directors and executive officers (the “D&O Indemnification Agreement”), embody the complete agreement and understanding among the parties and supersede and preempt any previous understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter in any way. For the avoidance of doubt, should defense or indemnification of Executive become an issue, if there is any conflict between this Employment Agreement, Exhibit “A” and the D&O Indemnification Agreement, that document or provision that provides the greatest protection to Executive shall prevail and be the operative agreement or provision.

(j)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. 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, 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.

(k)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.

(l)Successors and Assigns. Except as otherwise provided, 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.

(m)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.

(n)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; except Employer shall pay the costs of arbitration, and 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. The prevailing party in any arbitration shall be entitled to attorney’s fees and costs, subject to statutory limitations. Judgment upon the award rendered by the arbitrator(s) may be entered into any court having jurisdiction. The parties 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.

(o)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).

(p)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 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.

(q)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 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.

(r)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.

(s)Business Days. If any time period for giving notice or taking action 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.

(a)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, including, without limitation, any of the payments or benefits payable pursuant to Sections 1(b), 1(c), 1(d), 1(e) and 1(f). 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.

(a)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.

(b)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 before 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; and (ii) from any 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.

(c)Electronic Delivery. This Agreement, the agreements referred to, and each other agreement or instrument entered into in connection with this Agreement, and any amendments, 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 or party to any such agreement or instrument, each other party shall re-execute original forms 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.

(d)No Third-Party Beneficiaries. Except as expressly provided (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, 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(p) and shall be entitled to enforce such obligations as if a party hereto.

(e)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 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.

(f)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. 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 before the Employment Period.

IN WITNESS WHEREOF, the parties hereto have executed this Employment Agreement as of the date first above written.
