classes of stock in one of the other corporations in such chain. 
 (b)    “Base Salary”
means base pay (excluding incentive pay, premium pay, commissions, overtime, bonuses and other forms of variable compensation) as in effect prior to any reduction that would give rise to an officer’s right to a resignation for Good Reason.

Board has delegated authority to administer the Plan to the Compensation Committee of the Board, then “Board” shall also mean the Compensation Committee.

or series of related transactions to which the Company is a party in which in excess of 50% of the Company’s voting power is transferred; provided that the foregoing shall not include any transaction or series of transactions principally for

 (r)    “Good Reason” for an Eligible
Officer’s resignation from employment with the Company means the occurrence of any of the following actions are taken by the Company without such officer’s prior written consent: (i) a material reduction in such officer’s

in such officer’s duties (including responsibilities and/or authorities), provided, however, that a change in job position (including a change in title) shall not be deemed a “material reduction” in and of itself unless such

commute by more than 50 miles as compared to such officer’s then-current principal place of employment immediately prior to such relocation. In order to resign for Good Reason, such officer must provide written notice to the Company’s
Chief Executive Officer, or if such Eligible Officer is the Chief Executive Officer, must provide such written notice to the Company’s Board, within 30 days after the first occurrence of the event giving rise to Good Reason setting forth the
basis for such officer’s resignation, allow the Company at least 30 days from receipt of such written notice to cure such event, and if such event is not reasonably cured within such period, the officer must resign from all positions the

indirect interest (whether in the form of voting or participation in profits or capital contribution) of more than 50%. 












 Section 2.      ELIGIBILITY FOR
BENEFITS. 
 (a)    Eligible Officer. An officer of the Company is eligible to
participate in the Plan if (i) the Board has designated such officer as eligible to participate in the Plan by providing such person with a Participation Agreement; (ii) such officer has signed and returned such Participation Agreement to
the Company within the period specified therein; (iii) such officer’s employment with the Company terminates due to a Covered Termination; and (iv) such officer meets the other Plan eligibility requirements set forth in this
Section 2. The determination of whether an officer is an Eligible Officer shall be made by the Plan Administrator, in its sole discretion, and such determination shall be binding and conclusive on all persons. 

(b)    Release Requirement. In order to be eligible to receive benefits under the Plan, the Eligible Officer
also must execute a general waiver and release in such a form as provided by the Company (the “Release”), within the applicable time period set forth therein, and such Release must become effective in accordance with its
terms, which must occur in no event more than sixty (60) days following the date of the applicable Covered Termination. 

(c)    Plan Benefits Provided In Lieu of Individual Agreement Benefits. This Plan shall supersede any change
in control or severance benefit plan, policy or practice previously maintained by the Company with respect to an Eligible Officer and any change in control or severance benefits in any individually negotiated employment contract or other agreement
between the Company and an Eligible Officer, except to the extent such agreement specifically provides that its terms shall supersede and/or supplement the terms of the Plan. 

(d)    Exceptions to Benefit Entitlement. An officer who otherwise is an Eligible Officer will not receive
benefits under the Plan in the following circumstances, as determined by the Plan Administrator in its sole discretion: 

(1)    The officer voluntarily terminates employment with the Company without Good Reason, or terminates employment
due to the officer’s death or disability. Voluntary terminations include, but are not limited to, resignation, retirement or failure to return from a leave of absence on the scheduled date. 

(2)    The officer voluntarily terminates employment with the Company in order to accept employment with another
entity that is wholly or partly owned (directly or indirectly) by the Company or an Affiliate. 
 (3)    The
officer is offered an identical or substantially equivalent or comparable position with the Company or an Affiliate. For purposes of the foregoing, a “substantially equivalent or comparable position” is one that provides the officer
substantially the same level of responsibility and compensation and would not give rise to the officer’s right to a resignation for Good Reason. 

(4)    The officer is offered immediate reemployment by a successor to the Company or an Affiliate or by a
purchaser of the Company’s assets, as the case may be, following a Change in Control and the terms of such reemployment would not give rise to the officer’s right to resign for Good Reason. For purposes of the foregoing, “immediate
reemployment” means that the officer’s employment with the successor to the Company or an Affiliate or the purchaser of its assets, as the case may be, results in uninterrupted employment such that the officer does not incur a lapse
in pay or benefits as a result of the change in ownership of the Company or the sale of its assets. 












 (5)    The officer is rehired by the Company or an Affiliate and
recommences employment prior to the date benefits under the Plan are scheduled to commence. 

(e)    Termination or Reduction of Severance Benefits. An Eligible Officer’s right to receive benefits
under this Plan shall terminate immediately if, at any time prior to or during the period for which the Eligible Officer is receiving benefits under the Plan, the Eligible Officer, without the prior written approval of the Board willfully and
materially breaches any fiduciary, statutory, common law, or contractual obligation to the Company or an Affiliate (including, without limitation, the contractual obligations set forth in any confidential information and inventions assignment
agreement or similar type agreement between the Eligible Officer and the Company, as applicable). 

Section 3.      AMOUNT OF BENEFITS. 

(a)    Benefits in Participation Agreement. Benefits under the Plan, if any, shall be provided to an Eligible
Officer as set forth in the Participation Agreement. 
 (b)    Additional Benefits. Notwithstanding the
foregoing, the Company may, in its sole discretion, provide benefits to employees who are not Eligible Officers (“Non-Eligible Employees”) chosen by the Board, in its sole discretion,
and the provision of any such benefits to a Non-Eligible Employee shall in no way obligate the Company to provide such benefits to any other Non-Eligible Employee, even
if similarly situated. If benefits under the Plan are provided to a Non-Eligible Employee, references in the Plan to “Eligible Officer” (and similar references) shall be deemed to refer to such Non-Eligible Employee. 
 (c)    Certain Reductions. The Company, in its
sole discretion, shall have the authority to reduce an Eligible Officer’s severance benefits, in whole or in part, by any other severance benefits, pay and benefits provided during a period following written notice of a business closing or mass
layoff, pay and benefits in lieu of such notice, or other similar benefits payable to the Eligible Officer by the Company or an Affiliate that become payable in connection with the Eligible Officer’s termination of employment pursuant to
(i) any applicable legal requirement, including, without limitation, the Worker Adjustment and Retraining Notification Act or any other similar state law, (ii) any individually negotiated employment contract or agreement or any other
written employment or severance agreement with the Company, or (iii) any Company policy or practice providing for the Eligible Officer to remain on the payroll for a limited period of time after being given notice of the termination of the
Eligible Officer’s employment, and the Plan Administrator shall so construe and implement the terms of the Plan. Any such reductions that the Company determines to make pursuant to this Section 3(c) shall be made such that any severance
benefit under the Plan shall be reduced solely by any similar type of benefit under such legal requirement, agreement, policy or practice (i.e., any cash severance benefits under the Plan shall be reduced solely by any cash payments or
benefits under such legal requirement, agreement, policy or practice, and any continued insurance benefits under the Plan shall be reduced solely by any continued insurance benefits under such legal requirement, agreement, policy or practice). The
Company’s decision to apply such reductions to the severance benefits of one Eligible Officer and the amount of such reductions shall in no way obligate the Company to apply the same reductions in the same amounts to the severance benefits of
any other Eligible Officer, even if similarly situated. In the Company’s sole discretion, such reductions may be applied on a retroactive basis, with severance benefits previously paid being
re-characterized as payments pursuant to the Company’s statutory obligation. 












 (d)    Parachute Payments. If any payment or benefit an
Eligible Officer will or may receive from the Company or otherwise (a “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this
sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then any such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either
(x) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount (i.e., the
amount determined by clause (x) or by clause (y)), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in the
Eligible Officer’s receipt, on an after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in a Payment is
required pursuant to the preceding sentence and the Reduced Amount is determined pursuant to clause (x) of the preceding sentence, the reduction shall occur in the manner (the “Reduction Method”) that results in the
greatest economic benefit for the Eligible Officer. If more than one method of reduction will result in the same economic benefit, the items so reduced will be reduced pro rata (the “Pro Rata Reduction Method”). 

Notwithstanding any provisions in this Section above to the contrary, if the Reduction Method or the Pro Rata Reduction Method would result in
any portion of the Payment being subject to taxes pursuant to Section 409A that would not otherwise be subject to taxes pursuant to Section 409A, then the Reduction Method and/or the Pro Rata Reduction Method, as the case may be, shall be
modified so as to avoid the imposition of taxes pursuant to Section 409A as follows: (A) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for the Eligible Officer as
determined on an after-tax basis; (B) as a second priority, Payments that are contingent on future events (e.g., being terminated without Cause), shall be reduced (or eliminated) before Payments
that are not contingent on future events; and (C) as a third priority, Payments that are “deferred compensation” within the meaning of Section 409A shall be reduced (or eliminated) before Payments that are not deferred
compensation within the meaning of Section 409A. 
 The Company shall appoint a nationally recognized accounting or law firm to make
the determinations required by this Section. The Company shall bear all expenses with respect to the determinations by such accounting or law firm required to be made hereunder. The Company shall use commercially reasonable efforts to cause the
accounting or law firm engaged to make the determinations hereunder to provide its calculations, together with detailed supporting documentation, to Eligible Officer and the Company within 15 calendar days after the date on which Eligible
Officer’s right to a Payment becomes reasonably likely to occur (if requested at that time by Eligible Officer or the Company) or such other time as requested by Eligible Officer or the Company. 

If the Eligible Officer receives a Payment for which the Reduced Amount was determined pursuant to clause (x) above and the Internal
Revenue Service determines thereafter that some portion of the Payment is subject to the Excise Tax, Eligible Officer agrees to promptly return to the Company a sufficient amount of the Payment (after reduction pursuant to clause (x) above) so
that no portion of the remaining Payment is subject to the Excise Tax. For the avoidance of doubt, if the Reduced Amount was determined pursuant to clause (y) above, the Eligible Officer shall have no obligation to return any portion of the
Payment pursuant to the preceding sentence. 
 Section 4.      RETURN OF
COMPANY PROPERTY. 
 An Eligible Officer will not be entitled to any severance benefit under the Plan
unless and until the Eligible Officer returns all Company Property. For this purpose, “Company Property” means all Company documents (and all copies thereof), other Company property, and confidential, proprietary or trade secret
information which the Eligible Officer had in his or her possession at any time, including, but not 












 
limited to, Company files, notes, drawings, records, plans, forecasts, reports, studies, analyses, proposals, agreements, financial information, research and development information, sales and
marketing information, operational and personnel information, specifications, code, software, databases, computer-recorded information, tangible property and equipment (including, but not limited to, computers, facsimile machines, mobile telephones,
servers), credit cards, entry cards, identification badges and keys; and any materials of any kind which contain or embody any proprietary, confidential, or trade secret information of the Company (and all reproductions thereof in whole or in part).

 Section 5.      TIME OF PAYMENT AND FORM
OF BENEFITS. 
 The Company reserves the right in the Participation Agreement to specify whether severance
payments under the Plan will be paid in a single sum, in installments, or in any other form and to determine the timing of such payments. All such payments under the Plan will be subject to applicable withholding for federal, state and local taxes.
If an Eligible Officer is indebted to the Company on his or her termination date, the Company reserves the right to offset any severance payments under the Plan by the amount of such indebtedness. All severance benefits provided under the Plan are
intended to satisfy the requirements for an exemption from application of Section 409A of the Code to the maximum extent that an exemption is available and any ambiguities herein shall be interpreted accordingly; provided, however, that to the
extent such an exemption is not available, the severance benefits provided under the Plan are intended to comply with the requirements of Section 409A to the extent necessary to avoid adverse personal tax consequences and any ambiguities herein
shall be interpreted accordingly. 
 Notwithstanding anything to the contrary set forth herein, any payments and benefits provided under the
Plan that constitute “deferred compensation” within the meaning of Section 409A shall not commence in connection with an Eligible Officer’s termination of employment unless and until the Eligible Officer has also incurred a
“separation from service,” as such term is defined in Treasury Regulations Section 1.409A-1(h) (“Separation from Service”), unless the Company reasonably determines that
such amounts may be provided to the Eligible Officer without causing the Eligible Officer to incur the adverse personal tax consequences under Section 409A. 

It is intended that (i) each installment of any benefits payable under the Plan to an Eligible Officer be regarded as a separate
“payment” for purposes of Treasury Regulations Section 1.409A-2(b)(2)(i), (ii) all payments of any such benefits under the Plan satisfy, to the greatest extent possible, the exemptions from the
application of Section 409A provided under Treasury Regulations Sections 1.409A-1(b)(4), 1.409A-1(b)(5) and
1.409A-1(b)(9)(iii), and (iii) any such benefits consisting of COBRA premiums also satisfy, to the greatest extent possible, the exemption from the application of Section 409A provided under Treasury
Regulations Section 1.409A-1(b)(9)(v). However, if the Company determines that any such benefits payable under the Plan constitute “deferred compensation” under Section 409A and the
Eligible Officer is a “specified employee” of the Company, as such term is defined in Section 409A(a)(2)(B)(i), then, solely to the extent necessary to avoid the imposition of the adverse personal tax consequences under
Section 409A, (A) the timing of such benefit payments shall be delayed until the earlier of (1) the date that is six (6) months and one (1) day after the Eligible Officer’s Separation from Service and (2) the date
of the Eligible Officer’s death (such applicable date, the “Delayed Initial Payment Date”), and (B) the Company shall (1) pay the Eligible Officer a lump sum amount equal to the sum of the benefit payments that
the Eligible Officer would otherwise have received through the Delayed Initial Payment Date if the commencement of the payment of the benefits had not been delayed pursuant to this paragraph and (2) commence paying the balance, if any, of the
benefits in accordance with the applicable payment schedule. 
 In no event shall payment of any benefits under the Plan be made prior to an
Eligible Officer’s termination date or prior to the effective date of the Release. If the Company determines that any payments or benefits provided under the Plan constitute “deferred compensation” under Section 409A, and













 
the Eligible Officer’s Separation from Service occurs at a time during the calendar year when the Release could become effective in the calendar year following the calendar year in which the
Eligible Officer’s Separation from Service occurs, then regardless of when the Release is returned to the Company and becomes effective, the Release will not be deemed effective any earlier than the latest permitted effective date (the
“Release Deadline”). If the Company determines that any payments or benefits provided under the Plan constitute “deferred compensation” under Section 409A, then except to the extent that payments may be delayed
until the Delayed Initial Payment Date pursuant to the preceding paragraph, on the first regular payroll date following the effective date of an Eligible Officer’s Release, the Company shall (1) pay the Eligible Officer a lump sum amount
equal to the sum of the benefit payments that the Eligible Officer would otherwise have received through such payroll date but for the delay in payment related to the effectiveness of the Release and (2) commence paying the balance, if any, of
the benefits in accordance with the applicable payment schedule. 
 All severance payments under the Plan shall be subject to applicable
withholding for federal, state and local taxes. If an Eligible Officer is indebted to the Company at his or her termination date, the Company reserves the right to offset any severance payments under the Plan by the amount of such indebtedness. 

Section 6.      REEMPLOYMENT. 

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

Section 7.      RIGHT TO INTERPRET AND
ADMINISTER PLAN; AMENDMENT AND TERMINATION. 

(a)    Interpretation and Administration. Prior to the Closing, the Board shall be the Plan Administrator and
shall have the exclusive discretion and authority to establish rules, forms, and procedures for the administration of the Plan and to construe and interpret the Plan and to decide any and all questions of fact, interpretation, definition,
computation or administration arising in connection with the operation of the Plan, including, but not limited to, the eligibility to participate in the Plan and amount of benefits paid under the Plan. The rules, interpretations, computations and
other actions of the Board shall be binding and conclusive on all persons. Upon and after the Closing, the Plan will be interpreted and administered in good faith by the Representative who shall be the Plan Administrator during such period. All
actions taken by the Representative in interpreting the terms of the Plan and administering the Plan upon and after the Closing will be final and binding on all Eligible Officers. Any references in this Plan to the “Board” or “Plan
Administrator” with respect to periods following the Closing shall mean the Representative. 

(b)    Amendment. The Plan Administrator reserves the right to amend this Plan at any time; provided,
however, that any amendment of the Plan will not be effective as to a particular Eligible Officer who is or may be adversely impacted by such amendment or termination and has an effective Participation Agreement without the written consent of
such Eligible Officer. 
 (c)    Termination. The Plan will automatically terminate following satisfaction
of all the Company’s obligations under the Plan. 












 Section 8.      NO IMPLIED
EMPLOYMENT CONTRACT. 
 The Plan shall not be deemed (i) to give any officer or other person any right
to be retained in the employ of the Company or (ii) to interfere with the right of the Company to discharge any officer or other person at any time, with or without cause and with or without advance notice, which right is hereby
reserved. 
 Section 9.      LEGAL CONSTRUCTION. 

This Plan is intended to be governed by and shall be construed in accordance with the Employee Retirement Income Security Act of 1974
(“ERISA”) and, to the extent not preempted by ERISA, the laws of the State of California.

processing is required, written notice of the extension will be furnished to the applicant before the end of the initial ninety (90) day period. 

This notice of extension will describe the special circumstances necessitating the additional time and the date by which the Plan
Administrator is to render its decision on the application. 












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

her representative) relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. 

(d)    Decision on Review. The Plan Administrator will act on each request for review within sixty

 Section 13.    STATEMENT OF ERISA
RIGHTS. 
 Participants in this Plan (which is a welfare benefit plan sponsored by Lucira Health, Inc.) are entitled to
certain rights and protections under ERISA. If you are an Eligible Officer, you are considered a participant in the Plan and, under ERISA, you are entitled to: 

(a)    Receive Information About Your Plan and Benefits. 

(1)    Examine, without charge, at the Plan Administrator’s office and at other specified locations, such as
worksites, all documents governing the Plan and a copy of the latest annual report (Form 5500 Series), if applicable, filed by the Plan with the U.S. Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security
Administration; 
 (2)    Obtain, upon written request to the Plan Administrator, copies of documents governing
the operation of the Plan and copies of the latest annual report (Form 5500 Series), if applicable, and an updated (as necessary) Summary Plan Description. The Administrator may make a reasonable charge for the copies; and 

(3)    Receive a summary of the Plan’s annual financial report, if applicable. The Plan Administrator is
required by law to furnish each Eligible Officer with a copy of this summary annual report. 
 (b)    Prudent
Actions by Plan Fiduciaries. In addition to creating rights for Plan Eligible Officers, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan. The people who operate the Plan, called
“fiduciaries” of the Plan, have a duty to do so prudently and in the interest of you and other Eligible Officers and beneficiaries. No one, including your employer, your union or any other person, may fire you or otherwise discriminate
against you in any way to prevent you from obtaining a Plan benefit or exercising your rights under ERISA. 

(c)    Enforce Your Rights. If your claim for a Plan benefit is denied or ignored, in whole or in part, you
have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules. 

Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request a copy of Plan documents or the latest
annual report from the Plan, if applicable, and do not receive them within thirty (30) days, you may file suit in a Federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a
day until you receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. 

If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in a state or Federal court. 

If you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit
in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees,
for example, if it finds your claim is frivolous. 
 (d)    Assistance with Your Questions. If you have
any questions about the Plan, you should contact the Plan Administrator. If you have any questions about this statement or about your rights 












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

PARTICIPATION AGREEMENT 

Name:   ___________________ 

Section 1.      ELIGIBILITY. 

You have been designated as eligible to participate in the Lucira Health, Inc. Officer Severance Benefit Plan (the
“Plan”), a copy of which is attached as Annex I to this Participation Agreement (the “Agreement”). Capitalized terms not explicitly defined in this Agreement but defined in the Plan shall have the same
definitions as in the Plan. 
 Section 2.      SEVERANCE BENEFITS 

Subject to the terms of the Plan and Section 3 of this Agreement, if you are terminated in a Covered Termination, and meet all the other
eligibility requirements set forth in the Plan, including, without limitation, executing the required Release within the applicable time period set forth therein and provided that such Release becomes effective in accordance with its terms, you will
receive the severance benefits set forth in this Section 2. Notwithstanding the schedule for provision of severance benefits as set forth below, the provision of any severance benefits under this Section 2 is subject to any delay in
payment that may be required under Section 5 of the Plan. 
 (a)    Regular Termination. Upon a
Regular Termination, you shall be eligible to receive the following severance benefits. 
 (1)    Cash
Severance Benefit. You will be entitled to continue to receive your then-current Base Salary for [            ] months (such period of months, the “Severance
Period”) commencing on the first payroll period following the effective date of your Release. 

(2)    Payment of Continued Group Health Plan Benefits. 

(i)    If you timely elect continued group health plan continuation coverage under COBRA the Company shall pay the
full amount of your COBRA premiums, or shall provide coverage under any self-funded plan, on behalf of you for your continued coverage under the Company’s group health plans, including coverage for your eligible dependents, for [the Severance
Period] or [[                    ] months commencing with the first month following your Regular Termination] (the “COBRA Payment
Period”). Upon the conclusion of such period of insurance premium payments made by the Company, or the provision of coverage under a self-funded group health plan, you will be responsible for the entire payment of premiums (or payment
for the cost of coverage) required under COBRA for the duration of your eligible COBRA coverage period. For purposes of this Section, (i) references to COBRA shall be deemed to refer also to analogous provisions of state law and (ii) any
applicable insurance premiums that are paid by the Company shall not include any amounts payable by you under an Internal Revenue Code Section 125 health care reimbursement plan, which amounts, if any, are your sole responsibility. 












 (ii)    Notwithstanding the foregoing, if at any time the
Company determines, in its sole discretion, that it cannot provide the COBRA premium benefits without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section 2716 of the Public Health
Service Act), then in lieu of paying COBRA premiums on the your behalf, the Company will instead pay you on the last day of each remaining month of the COBRA Payment Period a fully taxable cash payment equal to the COBRA premium for that month,
subject to applicable tax withholding (such amount, the “Special Severance Payment”), such Special Severance Payment to be made without regard to your election of COBRA coverage or payment of COBRA premiums and without regard
to your continued eligibility for COBRA coverage during the COBRA Payment Period. Such Special Severance Payment shall end upon expiration of the COBRA Payment Period. 

(b)    Change in Control Termination. Upon a Change in Control Termination, you shall be eligible to receive
the following severance benefits. For the avoidance of doubt, in no event shall you be entitled to benefits under both Section 2(a) and this Section 2(b). If you are eligible for severance benefits under both Section 2(a) and this
Section 2(b), you shall receive the benefits set forth in this Section 2(b) and such benefits shall be reduced by any benefits previously provided to you under Section 2(a). 

(1)    Cash Severance Benefit. You will receive the cash severance benefit described in
Section 2(a)(1) above, except that: 
 (i)    your Severance Period will be
[                            ] months and Base Salary payment will be paid to you in a lump sum cash payment
no later than the first payroll cycle following the later of (i) the effective date of the Release or (ii) the Closing, but in any event not later than March 15 of the year following the year in which the Change in Control Termination
occurs; and 
 (ii)    you will additionally be entitled to the annual target cash bonus established for you, if
any, for the year in which the Change in Control Termination occurs, pro-rated for the period of time in which you provided services to the Company prior to your Change in Control Termination in the year in
which your Change in Control Termination occurs, payable in a lump sum cash payment no later than the first payroll cycle following the later of (i) the effective date of the Release or (ii) the Closing, but in any event not later than
March 15 of the year following the year in which the Change in Control Termination occurs. 

(2)    Accelerated Vesting of Stock Awards. 

(i)    Effective as of the later of the effective date of your Release or the effective date of the Closing, to the
extent not previously vested: (i) the vesting and exercisability of all outstanding stock options to purchase the Company’s common stock that are held by you on such date shall be accelerated in full, (ii) any reacquisition or
repurchase rights held by the Company in respect of common stock issued pursuant to any other stock award granted to you by the Company shall lapse in full, and (iii) the vesting of any other stock awards granted to you by the Company, and any
issuance of shares triggered by the vesting of such stock awards, including any restricted stock unit awards, shall be accelerated in full. Notwithstanding the foregoing, this Section 2(b)(2) shall not apply to stock awards issued under or held
in any Qualified Plan. For purposes of determining the number of shares that will vest pursuant to the foregoing provision with respect to any performance based vesting award that has multiple vesting levels depending upon the level of performance,
vesting acceleration shall occur with respect to the number of shares subject to the award as if the applicable performance criteria had been attained at a 100% level. 












 (ii)    If necessary to give effect to the intent of the
foregoing provision, notwithstanding anything to the contrary set forth in your stock award agreements or the applicable equity incentive plan under which such stock award was granted that provides that any then unvested portion of your award will
immediately expire upon your termination of service, the unvested portion of your stock award shall terminate on the earlier of (i) thirty (30) days following your Covered Termination or (ii) Closing, if sooner. 

(3)    Payment of Continued Group Health Plan Benefits. You will receive the payment for continued group
health plan benefits described in Section 2(a)(2) above, except that the COBRA Payment Period will be equal to the Severance Period applicable to a Change in Control Termination as set forth in Section 2(b)(1) above. 

Section 3.      DEFINITIONS.
