 Exhibit 10.9 
 VITAL THERAPIES, INC. 
 CHANGE OF CONTROL AND SEVERANCE AGREEMENT

 This Change of Control and Severance Agreement (the “Agreement”) is made and entered into by
and between [                    ] (“Executive”) and Vital Therapies, Inc., a Delaware corporation (the
“Company”), effective as of immediately prior to the effectiveness of the registration statement on Form S-1 filed with the U.S. Securities and Exchange Commission in connection with the Company’s proposed initial public
offering (the “Effective Date”). 
 RECITALS 

1. The Board of Directors of the Company (the “Board”), in consultation with the Compensation Committee of the
Board of Directors (the “Committee”) believes that it is in the best interests of the Company and its stockholders (i) to assure that the Company will have the continued dedication and objectivity of Executive,
notwithstanding the possibility, threat, or occurrence of a Change of Control and (ii) to provide Executive with an incentive to continue Executive’s employment prior to a Change of Control and to motivate Executive to maximize the value
of the Company upon a Change of Control for the benefit of its stockholders. 
 2. The Board believes that it is imperative to
provide Executive with certain severance benefits upon Executive’s termination of employment under certain circumstances. These benefits will provide Executive with enhanced financial security and incentive and encouragement to remain with the
Company notwithstanding the possibility of a Change of Control. 
 3. Certain capitalized terms used in the Agreement are
defined in Section 6 below. 
 AGREEMENT 
 NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto agree as follows: 
 1. Term of Agreement. If Executive becomes entitled to benefits under Section 3 during the term of this Agreement, the Agreement will not terminate until all of the obligations of the parties
hereto with respect to this Agreement have been satisfied. 
 2. At-Will Employment. The Company and Executive
acknowledge that Executive’s employment is and will continue to be at-will, as defined under applicable law. As an at-will employee, either the Company or the Executive may terminate the employment relationship at any time, with or without
Cause. Upon any termination of employment, the Company will pay Executive all accrued but unpaid vacation, expense reimbursements, wages and other benefits due to Executive under any Company-provided plans, policies and arrangements
(“Accrued Compensation”). 







 3. Severance Benefits. 

(a) Termination without Cause or Resignation for Good Reason Unrelated to a Change of Control. If the Company terminates
Executive’s employment with the Company without Cause (excluding death or Disability) or if Executive resigns from such employment for Good Reason, and, in each case, such termination occurs outside of the Change of Control Period, then
subject to Section 4, Executive will receive the following: 
 (i) Accrued Compensation. The Company will pay
Executive all Accrued Compensation. 
 (ii) Continuing Severance Payments. Executive will be paid
continuing payments of severance pay at a rate equal to Executive’s base salary rate, as then in effect, for a period of [CEO: twelve (12) / other executives: six (6)] months. The severance will be paid, less applicable withholdings, in
installments over the severance period with the first payment to commence on the sixty-first (61st) day following Executive’s termination of employment (and include any severance payments that otherwise would have been paid to Executive within the sixty (60) days following
Executive’s termination date), with any remaining payments paid in accordance with the Company’s normal payroll practices for the remainder of the severance period following Executive’s termination of employment (subject to any delay
as may be required by Section 4(c)). 
 (iii) Continuation Coverage. If Executive elects
continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) within the time period prescribed pursuant to COBRA for Executive and Executive’s eligible
dependents, then the Company will reimburse Executive for the COBRA premiums for such coverage (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (A) a period of [CEO: twelve
(12) / other executives: six (6)] months from the date of termination or (B) the date upon which Executive and/or Executive’s eligible dependents are no longer eligible for COBRA continuation coverage. The reimbursements will be made
by the Company to Executive consistent with the Company’s normal expense reimbursement policy. Notwithstanding the first sentence of this Section 3(a)(iii), if the Company determines in its sole discretion that it cannot provide the
foregoing benefit without potentially violating, or being subject to an excise tax under, applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will in lieu thereof provide to Executive a
taxable monthly payment, payable on the last day of a given month (except as provided by the following sentence), in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue the group health coverage for
Executive and/or Executive’s eligible dependents in effect on the termination of employment date (which amount will be based on the premium for the first month of COBRA coverage), which payments will be made regardless of whether Executive
and/or Executive’s eligible dependents elect COBRA continuation coverage and will commence on the month following Executive’s termination of employment and will end on the earlier of (x) the date upon which Executive obtains other
employment or (y) the date the Company has paid an amount equal to [CEO: twelve (12) / other executives: six (6)] payments. Any such taxable monthly payments that otherwise would have been paid to Executive within the sixty (60) days
following Executive’s termination date instead will be paid on the sixty-first (61st) day following 

  
 -2-









 
Executive’s termination of employment, with any remaining payments paid as provided in the prior sentence (subject to any delay as may be required by Section 4(c)). For the avoidance of
doubt, the taxable payments in lieu of COBRA reimbursements may be used for any purpose, including, but not limited to continuation coverage under COBRA, and will be subject to all applicable tax withholdings. 

(b) Termination without Cause or Resignation for Good Reason in Connection with a Change of Control. If the Company terminates
Executive’s employment with the Company without Cause (excluding death or Disability) or if Executive resigns from such employment for Good Reason, and, in each case, such termination occurs during the Change of Control Period, then
subject to Section 4, Executive will receive the following: 
 (i) Accrued Compensation. The Company will pay
Executive all Accrued Compensation. 
 (ii) Severance Payment. Executive will receive a lump-sum
payment (less applicable withholding taxes) equal to the [CEO: eighteen (18) / other executives: twelve (12)] months of Executive’s annual base salary as in effect immediately prior to Executive’s termination date or, if greater,
at the level in effect immediately prior to the Change of Control. The severance will be paid, less applicable withholdings, on the sixty-first (61st) day following Executive’s termination of employment (subject to any delay as may be required by
Section 4(c)). For the avoidance of doubt, if (x) Executive incurred a termination prior to a Change of Control that qualifies Executive for severance payments under Section 3(a)(ii); and (y) a Change of Control occurs within the
sixty (60) day following Executive’s termination of employment that qualifies Executive for the superior benefits under this Section 3(b)(ii), then Executive shall be entitled to a lump-sum payment of the amount calculated under this
Section 3(b)(ii), less amounts already paid under Section 3(a)(ii). 
 (iii) Bonus
Payment. Executive will receive a lump-sum payment equal to [CEO: one hundred and fifty percent (150%) / other executives: one hundred percent (100%)] of the higher of (A) the greater of (x) Executive’s target bonus as
in effect for the fiscal year in which the Change of Control occurs or (y) Executive’s target bonus as in effect for the fiscal year in which Executive’s termination of employment occurs, or (B) Executive’s actual bonus for
performance during the calendar year prior to the calendar year during which the termination of employment occurs. For avoidance of doubt, the amount paid to Executive pursuant to this Section 3(b)(iii) will not be prorated based on the
actual amount of time Executive is employed by the Company during the fiscal year (or the relevant performance period if something different than a fiscal year) during which the termination occurs. The bonus payment will be paid, less
applicable withholdings, on the sixty-first
(61st) day following Executive’s termination of
employment (subject to any delay as may be required by Section 4(c)). 
 (iv) Continuation Coverage. If Executive
elects continuation coverage pursuant to COBRA within the time period prescribed pursuant to COBRA for Executive and Executive’s eligible dependents, then the Company will reimburse Executive for the COBRA premiums for such coverage (at the
coverage levels in effect immediately prior to Executive’s termination) until the earlier of (A) a period of [CEO: eighteen (18) / other executives: twelve 

  
 -3-









 
(12)] months from the date of termination or (B) the date upon which Executive and/or Executive’s eligible dependents become covered under similar plans. The reimbursements will be made
by the Company to Executive consistent with the Company’s normal expense reimbursement policy. Notwithstanding the first sentence of this Section 3(b)(iv), if the Company determines in its sole discretion that it cannot provide the
foregoing benefit without potentially violating, or being subject to an excise tax under, applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will in lieu thereof provide to Executive a
taxable monthly payment, payable on the last day of a given month (except as provided by the following sentence), in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s group health
coverage in effect on the termination of employment date (which amount will be based on the premium for the first month of COBRA coverage), which payments will be made regardless of whether Executive elects COBRA continuation coverage and will
commence on the month following Executive’s termination of employment and will end on the earlier of (x) the date upon which Executive obtains other employment or (y) the date the Company has paid an amount equal to [CEO: eighteen
(18) / other executives: twelve (12)] payments. Any such payments that otherwise would have been paid to Executive within the sixty (60) days following Executive’s termination date instead will be paid on the sixty-first (61st) day following Executive’s termination of employment, with
any remaining payments paid as provided in the prior sentence (subject to any delay as may be required by Section 4(c)). For the avoidance of doubt, the taxable payments in lieu of COBRA reimbursements may be used for any purpose, including,
but not limited to continuation coverage under COBRA, and will be subject to all applicable tax withholdings. 
 (v)
Accelerated Vesting of Equity Awards. One hundred percent (100%) of Executive’s then-outstanding and unvested Equity Awards will become vested in full. If, however, an outstanding Equity Award is to vest and/or the amount of the
award to vest is to be determined based on the achievement of performance criteria, then the Equity Award will vest as to one hundred percent (100%) of the amount of the Equity Award assuming the performance criteria had been achieved at target
levels for the relevant performance period(s). 
 (c) Voluntary Resignation; Termination for Cause. If Executive’s
employment with the Company terminates (i) voluntarily by Executive (other than for Good Reason) or (ii) for Cause by the Company, then Executive will not be entitled to receive severance or other benefits except for those (if
any) as may then be established under the Company’s then existing severance and benefits plans and practices or pursuant to other written agreements with the Company. 

(d) Disability; Death. If the Company terminates Executive’s employment as a result of Executive’s Disability, or
Executive’s employment terminates due to Executive’s death, then Executive will not be entitled to receive any other severance or other benefits, except for those (if any) as may then be established under the Company’s then
existing written severance and benefits plans and practices or pursuant to other written agreements with the Company. 

  
 -4-









 (e) Exclusive Remedy. In the event of a termination of Executive’s employment as
set forth in Section 3(a) or (b) of this Agreement, the provisions of Section 3 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive or the Company otherwise may be entitled, whether
at law, tort or contract, in equity, or under this Agreement (other than the payment of accrued but unpaid wages, as required by law, and any unreimbursed reimbursable expenses). For the avoidance of doubt, Executive shall in no circumstances be
entitled to both the benefits pursuant to Section 3(a) and the benefits pursuant to Section 3(b). Executive will be entitled to no benefits, compensation or other payments or rights upon a termination of employment other than those
benefits expressly set forth in Section 3 of this Agreement. 
 4. Conditions to Receipt of Severance 

(a) Release of Claims Agreement. The receipt of any severance payments or benefits (other than the Accrued Compensation set forth
in either Sections 3(a)(i) or 3(b)(i)) pursuant to this Agreement is subject to Executive signing and not revoking the Company’s then-standard separation agreement and release of claims (the “Release”), which
must become effective and irrevocable no later than the sixtieth (60th) day following Executive’s termination of employment (the “Release Deadline”). If the Release does not become effective and irrevocable by the
Release Deadline, Executive will forfeit any right to severance payments or benefits under this Agreement. In no event will severance payments or benefits be paid or provided until the Release actually becomes effective and irrevocable.

 (b) Confidential Information and Invention Assignment Agreements. Executive’s receipt of any payments or benefits
under Section 3 (other than the accrued benefits set forth in either Sections 3(a)(i) or 3(b)(i)) will be subject to Executive continuing to comply with the terms of the Employee Innovations and Proprietary Rights Assignment Agreement
that Executive executed when joining the Company, as such agreement may be amended from time to time. 
 (c)
Section 409A. 
 (i) Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be
paid or provided to Executive, if any, pursuant to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Section 409A of the Code, and the final
regulations and any guidance promulgated thereunder (“Section 409A”) (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has a “separation from
service” within the meaning of Section 409A. Similarly, no severance payable to Executive, if any, pursuant to this Agreement that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9) will be payable until Executive has a “separation from service” within the meaning of Section 409A. 

(ii) Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of
Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Payments, if any, that are payable within the first six (6) months following Executive’s separation from service, will become
payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. All subsequent Deferred


  
 -5-









 
Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following
Executive’s separation from service, but before the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable
after the date of Executive’s death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute a
separate payment under Section 1.409A-2(b)(2) of the Treasury Regulations. 
 (iii) It is intended that any amount
paid under this Agreement that satisfies the requirements of the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of clause
(i) above. 
 (iv) It is intended that any amount paid under this Agreement that qualifies as a payment made as a result
of an involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments for purposes of
clause (i) above. 
 (v) The foregoing provisions are intended to comply with the requirements of Section 409A so
that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and Executive agree to work
together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition before actual payment to Executive
under Section 409A. Executive agrees and acknowledges that the Company makes no representations or warranties with respect to the application of Section 409A and other tax consequences to any payments hereunder and, by the acceptance of
any such payments, Executive agrees to accept the potential application of Section 409A and the other tax consequences of any payments made hereunder. 
 5. Limitation on Payments. In the event that the severance and other benefits provided for in this Agreement or otherwise payable to Executive (i) constitute “parachute payments”
within the meaning of Section 280G of the Code, and (ii) but for this Section 5, would be subject to the excise tax imposed by Section 4999 of the Code, then Executive’s severance benefits will be either: 

(a) delivered in full, or 
 (b) delivered as to such lesser extent which would result in no portion of such severance benefits being subject to excise tax under Section 4999 of the Code, 

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by
Section 4999, results in the receipt by Executive on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. If a reduction in
severance and other benefits constituting “parachute payments” is necessary so that benefits are delivered to a lesser extent, reduction will occur in the following order: (i) reduction of cash payments;


  
 -6-









 
(ii) cancellation of awards granted “contingent on a change in ownership or control” (within the meaning of Code Section 280G), (iii) cancellation of accelerated vesting
of equity awards; or (iv) reduction of employee benefits. In the event that acceleration of vesting of equity award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of
Executive’s equity awards. 
 A nationally recognized certified professional services firm selected by the Company, the
Company’s legal counsel or such other person or entity to which the parties mutually agree (the “Firm”) shall perform the foregoing calculations related to the Excise Tax. The Company shall bear all expenses with respect
to the determinations by the Firm required to be made hereunder. For purposes of making the calculations required by this Section, the Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable,
good faith interpretations concerning the application of Code Sections 280G and 4999. The Company and Executive will furnish to the Firm such information and documents as the Firm may reasonably request in order to make a determination under this
Section. The Firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the Company and Executive within fifteen (15) calendar days after the date on which
Executive’s right to the severance benefits or other payments is triggered (if requested at that time by the Company or Executive) or such other time as requested by the Company or Executive. Any good faith determinations of the Firm made
hereunder shall be final, binding, and conclusive upon the Company and Executive. 
 6. Definition of Terms. The
following terms referred to in this Agreement will have the following meanings: 
 (a) Cause.
“Cause” will mean: 
 (i) Executive’s material failure to perform Executive’s stated duties,
and Executive’s continued failure to cure such failure to the reasonable satisfaction of the Company within ten (10) days following written notice of such failure to Executive from the Board; 

(ii) Executive’s material violation of a Company policy (including any insider trading policy) or material breach of any written
agreement or covenant with the Company, including, but not limited to, any applicable invention assignment and confidentiality agreement or similar agreement between the Company and Executive; 

(iii) Executive’s conviction of, or entry of a plea of guilty or nolo contendere to, a felony (other than motor vehicle
offenses the effect of which do not materially impair Executive’s performance of his employment duties); 
 (iv) a willful
act by Executive that constitutes gross misconduct and which is injurious to the Company; 
 (v) Executive’s commission of
any act of fraud or embezzlement; 

  
 -7-









 (vi) Executive’s commission of any act of dishonesty or any other willful misconduct
that has caused or is reasonably expected to result in a material injury to the Company; or 
 (vii) Executive’s willful
failure to cooperate with an investigation authorized by the Board or initiated by a governmental authority, in either case, relating to the Company, its business, or any of its directors, officers or employees. 

The determination as to whether Executive is being terminated for Cause will be made in good faith by the Board and will be final and binding on
Executive. The foregoing definition does not in any way limit the Company’s ability to terminate Executive’s employment relationship at any time as provided in Section 2 above, and the term “Company” will be interpreted to
include any subsidiary, parent, affiliate or successor thereto, if applicable. 
 (b) Change of Control.
“Change of Control” means the occurrence of any of the following events: 
 (i) A change in the
ownership of the Company which occurs on the date that any one Person, or more than one Person acting as a group (collectively, a “Person” for purposes of this definition), acquires ownership of the stock of the Company that,
together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the Company; provided, however, that for purposes of this subsection, (a) the acquisition of additional stock
by any one Person, who is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company, will not be considered a Change of Control and (b) the acquisition of additional stock of the Company by a
Permitted Holder that, together with the stock held by such Person and its Affiliates and/or Associates, constitutes more than fifty percent (50%) of the total voting power of the stock of the Company, will not be considered a Change of Control
so long as such acquisition is not in connection with a transaction that results in the Company ceasing to have any class of securities registered under the Securities and Exchange Act of 1934, as amended (i.e., a “going-private”
transaction) ; or 
 (ii) A change in the effective control of the Company which occurs on the date that a majority of members
of the Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause
(ii), (a) if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change of Control and (b) any member of the Board that is
nominated by any Permitted Holder shall be considered endorsed by a majority of the members of the Board; or 
 (iii) A change
in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such Person or
Persons) assets from the Company that have a total gross fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or
acquisitions; provided, however, that for purposes of this subsection (iii), the following will not constitute a change in the ownership of a substantial 

  
 -8-









 
portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by
the Company to: (1) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of the total value or voting power
of which is owned, directly or indirectly, by the Company, (3) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity,
at least fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a Person described in this subsection (iii)(B)(3). For purposes of this subsection (iii), gross fair market value means the value of
the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 
 For purposes of this definition, Persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or
similar business transaction with the Company. 
 Notwithstanding the foregoing, a transaction will not be deemed a Change of
Control unless the transaction qualifies as a change in control event within the meaning of Code Section 409A, as it has been and may be amended from time to time, and any proposed or final Treasury Regulations and Internal Revenue Service
guidance that has been promulgated or may be promulgated thereunder from time to time. 
 For purposes of this definition, a
“Permitted Holder” shall mean any Person that, individually or together with all of such Person’s Affiliates and/or Associates, is the Owner of fifteen percent (15%) or more of the outstanding Voting Stock of the
Corporation at the time of the Company’s Initial Public Offering or any of such Person’s Affiliates or Associates. All capitalized terms in the immediately preceding sentence that are not otherwise defined in this Agreement shall have the
meanings given to such terms in the Company’s Amended and Restated Certificate of Incorporation as in effect immediately following the Company’s initial public offering of its Common Stock pursuant to an effective registration statement
under the Securities Act of 1933, as amended (the “Initial Public Offering”). 
 Further and for the
avoidance of doubt, a transaction will not constitute a Change of Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in
substantially the same proportions by the persons who held the Company’s securities immediately before such transaction. 

(c) Change of Control Period. “Change of Control Period” will mean the period beginning on the date two
(2) months prior to, and ending on the date that is twelve (12) months following, a Change of Control. 
 (d)
Code. “Code” will mean the Internal Revenue Code of 1986, as amended. 
 (e) Disability.
“Disability” will mean that Executive has been unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be
expected to last for a 

  
 -9-









 
continuous period of not less than twelve (12) months. Alternatively, Executive will be deemed disabled if determined to be totally disabled by the Social Security Administration.
Termination resulting from Disability may only be effected after at least thirty (30) days’ written notice by the Company of its intention to terminate Executive’s employment. In the event that Executive resumes the performance of
substantially all of Executive’s duties hereunder before the termination of Executive’s employment becomes effective, the notice of intent to terminate based on Disability will automatically be deemed to have been revoked. 

(f) Equity Awards. “Equity Awards” will mean Executive’s outstanding stock options, stock
appreciation rights, restricted stock, restricted stock units, performance shares, performance stock units and any other Company equity compensation awards. 
 (g) Good Reason. “Good Reason” will mean Executive’s voluntary termination, within thirty (30) days following the expiration of any Company cure period (discussed
below) following the occurrence of one or more of the following, without Executive’s consent: 
 (i) a material
reduction of Executive’s authority, duties or responsibilities, relative to Executive’s authority, duties or responsibilities in effect immediately prior to such reduction, or, following a Change of Control[, provided, however, that
continued employment following the Change of Control with substantially the same responsibility with respect to the Company’s business and operations will not constitute “Good Reason” (for example, Executive will not have been removed
from Executive’s position if Executive is employed by the Company and Executive has substantially the same responsibilities with respect to the business of the Company as Executive had immediately prior to the Change of Control whether
Executive’s title is revised to reflect Executive’s placement within the overall corporate hierarchy and whether Executive provides services and/or reports to a subsidiary, affiliate, business unit or otherwise)]1; 

(ii) a material reduction by the Company of Executive’s annual base salary as in effect on the Effective Date (or, if lower, as in
effect immediately prior to the reduction), except to the extent the base salaries of all other senior executives of the Company are similarly reduced; 
 (iii) the failure of the Company to obtain assumption of this Agreement by any successor; or 
 (iv) a material change in the geographic location of Executive’s principal workplace; provided, that a relocation of less than fifty (50) miles from San Diego, California will not be considered
a material change in geographic location. 
 Executive may not resign for Good Reason without first providing the Company with written notice
within ninety (90) days of the initial existence of the condition that he believes constitutes Good Reason specifically identifying the acts or omissions constituting the grounds for Good Reason and a reasonable cure period of not less than
thirty (30) days following the date of such notice.

 For purposes of the “Good Reason” definition, the term “Company” will be interpreted to
include any subsidiary, parent, affiliate or successor thereto, if applicable. 
 (h) Section 409A Limit.
“Section 409A Limit” will mean two (2) times the lesser of: (i) Executive’s annualized compensation based upon the annual rate of pay paid to Executive during the Executive’s taxable year preceding the
Executive’s taxable year of Executive’s termination of employment as determined under, and with such adjustments as are set forth in, Treasury Regulation 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with
respect thereto; or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which Executive’s employment is terminated. 

7. Successors. 
 (a) The Company’s Successors. Any successor to the Company (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or otherwise) to all or substantially
all of the Company’s business and/or assets will assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same manner and to the same extent as the Company would be required to
perform such obligations in the absence of a succession. For all purposes under this Agreement, the term “Company” will include any successor to the Company’s business and/or assets which executes and delivers the assumption agreement
described in this Section 7(a) or which becomes bound by the terms of this Agreement by operation of law. 
 (b)
Executive’s Successors. The terms of this Agreement and all rights of Executive hereunder will inure to the benefit of, and be enforceable by, Executive’s personal or legal representatives, executors, administrators, successors,
heirs, distributees, devisees and legatees.

duly given when sent electronically or personally delivered when mailed by U.S. registered or certified mail, return receipt requested and postage prepaid or when delivered by a private courier service such as UPS, DHL or Federal Express that has
tracking capability. In the case of Executive, notices will be sent to the e-mail address or addressed to Executive at the home address, in either case which Executive most recently communicated to the Company in writing. In the case of the Company,
electronic notices will be sent to the e-mail address of the [Chief Executive Officer] and mailed notices will be addressed to its corporate headquarters, and all notices will be directed to the attention of its [Chief Executive Officer.]2

for Good Reason will be communicated by a notice of termination to the other party hereto given in accordance with Section 8(a) of this Agreement. Such notice will indicate the specific termination provision in this Agreement relied upon, will
set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination under the provision so indicated, and will specify the termination date (which will be not more than ninety (90) days after the giving of such
notice). 
 9. Resignation. Upon the termination of Executive’s employment for any reason, Executive will be deemed
to have resigned from all officer [and/or director]3
positions held at the Company and its affiliates voluntarily, without any further required action by Executive, as of the end of Executive’s employment and Executive, at the Board’s request, will execute any documents reasonably
necessary to reflect Executive’s resignation. 
 10. Arbitration. 

(a) Arbitration. In consideration of Executive’s employment with the Company, its promise to arbitrate all
employment-related disputes, and Executive’s receipt of the compensation, pay raises and other benefits paid to Executive by the Company, at present and in the future, Executive agrees that any and all controversies, claims, or disputes
with anyone (including the Company and any employee, officer, director, stockholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s employment with the
Company or termination thereof, including any breach of this Agreement, will be subject to binding arbitration under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 through 1294.2, including
Section 1281.8 (the “Act”), and pursuant to California law. The Federal Arbitration Act will also apply with full force and effect, notwithstanding the application of procedural rules set forth under the Act. 

(b) Dispute Resolution. Disputes that Executive agrees to arbitrate, and thereby agrees to waive any right to a trial by jury,
include any statutory claims under local, state, or federal law, including, but not limited to, claims under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age Discrimination in Employment Act of
1967, the Older Workers Benefit Protection Act, the Sarbanes Oxley Act, the Worker Adjustment and Retraining Notification Act, the California Fair Employment and Housing Act, the Family and Medical Leave Act, the California Family Rights Act, the
California Labor Code, claims of harassment, discrimination, and wrongful termination, and any statutory or common law claims. Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with
Executive. 
 (c) Procedure. Executive agrees that any arbitration will be administered by the Judicial
Arbitration & Mediation Services, Inc. (“JAMS”), pursuant to its Employment Arbitration Rules & Procedures (the “JAMS Rules”). The arbitrator will have the power to decide any motions
brought by any party to the arbitration, including motions for summary

judgment and/or adjudication, motions to dismiss and demurrers, and motions for class certification, prior to any arbitration hearing. The arbitrator will have the power to award any remedies
available under applicable law, and the arbitrator will award attorneys’ fees and costs to the prevailing party, except as prohibited by law. The Company will pay for any administrative or hearing fees charged by the administrator or JAMS, and
all arbitrator’s fees, except that Executive will pay any filing fees associated with any arbitration that Executive initiates, but only so much of the filing fee as Executive would have instead paid had Executive filed a complaint in a court
of law. Executive agrees that the arbitrator will administer and conduct any arbitration in accordance with California law, including the California Code of Civil Procedure and the California Evidence Code, and that the arbitrator will apply
substantive and procedural California law to any dispute or claim, without reference to the rules of conflict of law. To the extent that the JAMS Rules conflict with California law, California law will take precedence. The decision of the arbitrator
will be in writing. Any arbitration under this Agreement will be conducted in San Diego County, California. 
 (d)
Remedy. Except as provided by the Act, arbitration will be the sole, exclusive, and final remedy for any dispute between Executive and the Company. Accordingly, except as provided by the Act and this Agreement, neither Executive nor the
Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will not have the authority to disregard or refuse to enforce any lawful Company policy, and the
arbitrator will not order or require the Company to adopt a policy not otherwise required by law which the Company has not adopted. 
 (e) Administrative Relief. Executive is not prohibited from pursuing an administrative claim with a local, state, or federal administrative body or government agency that is authorized to enforce
or administer laws related to employment, including, but not limited to, the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission, the National Labor Relations Board, or the Workers’ Compensation Board.
However, Executive may not pursue court action regarding any such claim, except as permitted by law. 
 (f) Voluntary Nature
of Agreement. Executive acknowledges and agrees that Executive is executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Executive further acknowledges and agrees that Executive has
carefully read this Agreement and that Executive has asked any questions needed for Executive to understand the terms, consequences and binding effect of this Agreement and fully understands it, including that EXECUTIVE IS WAIVING
EXECUTIVE’S RIGHT TO A JURY TRIAL. Finally, Executive agrees that Executive has been provided an opportunity to seek the advice of an attorney of Executive’s choice before signing this Agreement. 

11. Miscellaneous Provisions. 
 (a) No Duty to Mitigate. Executive will not be required to mitigate the amount of any payment contemplated by this Agreement, nor will any such payment be reduced by any earnings that Executive may
receive from any other source.

 (b) Waiver. No provision of this Agreement will be modified, waived or discharged
unless the modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any breach of, or of compliance with, any condition or
provision of this Agreement by the other party will be considered a waiver of any other condition or provision or of the same condition or provision at another time. 
 (c) Headings. All captions and section headings used in this Agreement are for convenient reference only and do not form a part of this Agreement. 

(d) Entire Agreement. This Agreement constitutes the entire agreement of the parties hereto and supersedes in their entirety all
prior representations, understandings, undertakings or agreements (whether oral or written and whether expressed or implied) of the parties with respect to the subject matter hereof, including, but not limited to, any rights to extended
post-termination exercise period, severance and/or change of control benefits set forth in any prior employment agreement or offer letter, option agreement, or similar agreement (or amendment thereto). No waiver, alteration, or modification of any
of the provisions of this Agreement will be binding unless in writing and signed by duly authorized representatives of the parties hereto and which specifically mention this Agreement. 

(e) Choice of Law. The validity, interpretation, construction and performance of this Agreement will be governed by the laws of
the State of California (with the exception of its conflict of laws provisions). Any claims or legal actions by one party against the other arising out of the relationship between the parties contemplated herein (whether or not arising under this
Agreement) will be commenced or maintained in any state or federal court located in the jurisdiction where Executive resides, and Executive and the Company hereby submit to the jurisdiction and venue of any such court. 

(f) Severability. The invalidity or unenforceability of any provision or provisions of this Agreement will not affect the validity
or enforceability of any other provision hereof, which will remain in full force and effect. 
 (g) Withholding. All
payments made pursuant to this Agreement will be subject to withholding of applicable income, employment and other taxes. 
 (h)
Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.
