 1. PURPOSE. The purpose of this Plan is
to provide incentives to attract, retain and motivate eligible persons whose present and potential contributions are important to the success of the Company, its Parent and Subsidiaries, by offering them an opportunity to participate in the
Company’s future performance through awards of Options and Restricted Stock. Capitalized terms not defined in the text are defined in Section 22 hereof. Although this Plan is intended to be a written compensatory benefit plan within the
meaning of Rule 701 promulgated under the Securities Act, grants may be made pursuant to this plan which do not qualify for exemption under Rule 701 or Section 25102(o) of the California Corporations Code. Any requirement of this Plan
which is required in law only because of Section 25102(o) need not apply if the Committee so provides. 
 2. SHARES
SUBJECT TO THE PLAN. 
 2.1 Number of Shares Available. Subject to Sections 2.2 and 17, the total number
of Shares reserved and available for grant and issuance pursuant to this Plan will be 10,924,040 Shares. Subject to Sections 2.2, 5.10 and 17 hereof, Shares subject to Awards previously granted will again be available for grant and issuance in
connection with future Awards under this Plan to the extent such Shares: (i) cease to be subject to issuance upon exercise of an Option, other than due to exercise of such Option; (ii) are subject to an Award granted hereunder but the
Shares subject to such Award are forfeited or repurchased by the Company at the original issue price; or (iii) are subject to an Award that otherwise terminates without Shares being issued. At all times the Company will reserve and keep
available a sufficient number of Shares as will be required to satisfy the requirements of all Awards granted and outstanding under this Plan. 







 2.2 Adjustment of Shares. In the event that the number of outstanding shares
of the Company’s Common Stock is changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of the Company without consideration, then
(i) the number of Shares reserved for issuance under this Plan, (ii) the Exercise Prices of and number of Shares subject to outstanding Options and (iii) the Purchase Prices of and number of Shares subject to other outstanding Awards
will be proportionately adjusted, subject to any required action by the Board or the stockholders of the Company and compliance with applicable securities laws; provided, however, that fractions of a Share will not be issued but will either be paid
in cash at the Fair Market Value of such fraction of a Share or will be rounded down to the nearest whole Share, as determined by the Committee; and provided, further, that the Exercise Price of any Option may not be decreased to below the par value
of the Shares. 
 3. ELIGIBILITY. ISOs (as defined in Section 5 hereof) may be granted only to employees
(including officers and directors who are also employees) of the Company or of a Parent or Subsidiary of the Company. NQSOs (as defined in Section 5 hereof) and Restricted Stock Awards may be granted to employees, officers, directors and
consultants of the Company or any Parent or Subsidiary of the Company; provided such consultants render bona fide services not in connection with the offer and sale of securities in a capital-raising transaction. A person may be granted more than
one Award under this Plan. 
 4. ADMINISTRATION. 
 4.1 Committee Authority. This Plan will be administered by the Committee or the Board if no Committee is created by the Board.
Subject to the general purposes, terms and conditions of this Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan. Without limitation, the Committee will have the authority to: 

(a) construe and interpret this Plan, any Award Agreement and any other agreement or document executed pursuant to this Plan;

 (b) prescribe, amend and rescind rules and regulations relating to this Plan; 
 (c) approve persons to receive Awards; 
 (d) determine the form and terms of Awards; 
 (e) determine the number of Shares
or other consideration subject to Awards; 
 (f) determine whether Awards will be granted singly, in combination with, in
tandem with, in replacement of, or as alternatives to, other Awards under this Plan or awards under any other incentive or compensation plan of the Company or any Parent or Subsidiary of the Company; 
  

 2 








 (g) grant waivers of any conditions of this Plan or any Award; 
 (h) determine the terms of vesting, exercisability and payment of Awards; 
 (i) correct any defect, supply any omission, or reconcile any inconsistency in this Plan, any Award, any Award Agreement, any Exercise
Agreement or any Restricted Stock Purchase Agreement; 
 (j) determine whether an Award has been earned; 
 (k) make all other determinations necessary or advisable for the administration of this Plan; and 
 (l) extend the vesting period beyond a Participant’s Termination Date. 
 4.2 Committee Discretion. Unless in contravention of any express terms of this Plan or Award, any determination made by the
Committee with respect to any Award will be made in its sole discretion either (i) at the time of grant of the Award, or (ii) subject to Section 5.9 hereof, at any later time. Any such determination will be final and binding on the
Company and on all persons having an interest in any Award under this Plan. The Committee may delegate to one or more officers of the Company the authority to grant an Award under this Plan, provided such officer or officers are members of the
Board. 
 5. OPTIONS. The Committee may grant Options to eligible persons described in Section 3 hereof and
will determine whether such Options will be Incentive Stock Options within the meaning of the Code (“ISOs”) or Nonqualified Stock Options (“NQSOs”), the number of Shares subject to the Option, the
Exercise Price of the Option, the period during which the Option may be exercised, and all other terms and conditions of the Option, subject to the following: 
 5.1 Form of Option Grant. Each Option granted under this Plan will be evidenced by an Award Agreement which will expressly identify the Option as an ISO or an NQSO (“Stock Option
Agreement”), and will be in such form and contain such provisions (which need not be the same for each Participant) as the Committee may from time to time approve, and which will comply with and be subject to the terms and conditions of
this Plan. 
 5.2 Date of Grant. The date of grant of an Option will be the date on which the Committee makes the
determination to grant such Option, unless a later date is otherwise specified by the Committee. The Stock Option Agreement and a copy of this Plan will be delivered to the Participant within a reasonable time after the granting of the Option.

 5.3 Exercise Period. Options may be exercisable immediately but subject to repurchase pursuant to
Section 11 hereof or may be exercisable within the times or upon the events determined by the Committee as set forth in the Stock Option Agreement governing such Option; provided, however, that no Option will be exercisable after the expiration
of ten (10) years from the date the Option is granted; and provided further that no ISO granted to a person who directly or by attribution owns more than ten percent (10%) of the total combined voting

  

 3 








 
power of all classes of stock of the Company or of any Parent or Subsidiary of the Company (“Ten Percent Stockholder”) will be exercisable after the expiration of five
(5) years from the date the ISO is granted. The Committee also may provide for Options to become exercisable at one time or from time to time, periodically or otherwise, in such number of Shares or percentage of Shares as the Committee
determines. Subject to earlier termination of the Option as provided herein, to the extent section 25102(o) of the California Corporations Code is intended to apply, each Participant who is not an officer, director or consultant of the Company or of
a Parent or Subsidiary of the Company shall have the right to exercise an Option granted hereunder at the rate of no less than twenty percent (20%) per year over five (5) years from the date such Option is granted. 
 5.4 Exercise Price. The Exercise Price of an Option will be determined by the Committee when the Option is granted and may not
be less than eighty-five percent (85%) of the Fair Market Value of the Shares on the date of grant; provided that (i) the Exercise Price of an ISO will not be less than one hundred percent (100%) of the Fair Market Value of the Shares
on the date of grant and (ii) the Exercise Price of any Option granted to a Ten Percent Stockholder will not be less than one hundred ten percent (110%) of the Fair Market Value of the Shares on the date of grant. Payment for the Shares
purchased must be made in accordance with Section 7 hereof. 
 5.5 Method of Exercise. Options may be
exercised only by delivery to the Company of a written stock option exercise agreement (the “Exercise Agreement”) in a form approved by the Committee (which need not be the same for each Participant). The Exercise Agreement
will state (i) the number of Shares being purchased, (ii) the restrictions imposed on the Shares purchased under such Exercise Agreement, if any, and (iii) such representations and agreements regarding Participant’s investment
intent and access to information and other matters, if any, as may be required or desirable by the Company to comply with applicable securities laws. Participant shall execute and deliver to the Company the Exercise Agreement together with payment
in full of the Exercise Price, and any applicable taxes, for the number of Shares being purchased. 
 5.6
Termination. Subject to earlier termination pursuant to Sections 17 and 18 hereof and notwithstanding the exercise periods set forth in the Stock Option Agreement, exercise of an Option will always be subject to the following:

 (a) If the Participant is Terminated for any reason other than death, Disability or for Cause, then the Participant may
exercise such Participant’s Options only to the extent that such Options are exercisable as to Vested Shares upon the Termination Date or as otherwise determined by the Committee. Such Options must be exercised by the Participant, if at all, as
to all or some of the Vested Shares calculated as of the Termination Date or such other date determined by the Committee, within three (3) months after the Termination Date (or within such shorter time period, not less than thirty
(30) days, or within such longer time period, not exceeding five (5) years, after the Termination Date as may be determined by the Committee, with any exercise beyond three (3) months after the Termination Date deemed to be an NQSO)
but in any event, no later than the expiration date of the Options. 
  

 4 








 (b) If the Participant is Terminated because of Participant’s death or Disability (or
the Participant dies within three (3) months after a Termination other than for Cause), then Participant’s Options may be exercised only to the extent that such Options are exercisable as to Vested Shares by Participant on the Termination
Date or as otherwise determined by the Committee. Such options must be exercised by Participant (or Participant’s legal representative or authorized assignee), if at all, as to all or some of the Vested Shares calculated as of the Termination
Date or such other date determined by the Committee, within twelve (12) months after the Termination Date (or within such shorter time period, not less than six (6) months, or within such longer time period, not exceeding five
(5) years, after the Termination Date as may be determined by the Committee, with any exercise beyond (i) three (3) months after the Termination Date when the Termination is for any reason other than the Participant’s death or
disability, within the meaning of Section 22(e)(3) of the Code, or (ii) twelve (12) months after the Termination Date when the Termination is for Participant’s disability, within the meaning of Section 22(e)(3) of the Code,
deemed to be an NQSO) but in any event no later than the expiration date of the Options. 
 (c) If the Participant is
terminated for Cause, the Participant may exercise such Participant’s Options, but not to an extent greater than such Options are exercisable as to Vested Shares upon the Termination Date and Participant’s Options shall expire on such
Participant’s Termination Date, or at such later time and on such conditions as are determined by the Committee. 
 5.7
Limitations on Exercise. The Committee may specify a reasonable minimum number of Shares that may be purchased on any exercise of an Option, provided that such minimum number will not prevent Participant from exercising the Option for the
full number of Shares for which it is then exercisable. 
 5.8 Limitations on ISOs. The aggregate Fair Market
Value (determined as of the date of grant) of Shares with respect to which ISOs are exercisable for the first time by a Participant during any calendar year (under this Plan or under any other incentive stock option plan of the Company or any Parent
or Subsidiary of the Company) will not exceed One Hundred Thousand Dollars ($100,000). If the Fair Market Value of Shares on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year
exceeds One Hundred Thousand Dollars ($100,000), then the Options for the first One Hundred Thousand Dollars ($100,000) worth of Shares to become exercisable in such calendar year will be ISOs and the Options for the amount in excess of One Hundred
Thousand Dollars ($100,000) that become exercisable in that calendar year will be NQSOs. In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date (as defined in Section 18 hereof) to provide for
a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, then such different limit will be automatically incorporated herein and will apply to any Options granted after the effective date of such amendment. 

5.9 Modification, Extension or Renewal. The Committee may modify, extend or renew outstanding Options and authorize the
grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any of such Participant’s rights under any Option previously granted. Any outstanding ISO that is
modified, extended, renewed or otherwise altered will be treated in accordance with

  

 5 








 
Section 424(h) of the Code. Subject to Section 5.10 hereof, the Committee may reduce the Exercise Price of outstanding Options without the consent of Participants by a written notice to
them; provided, however, that the Exercise Price may not be reduced below the minimum Exercise Price that would be permitted under Section 5.4 hereof for Options granted on the date the action is taken to reduce the Exercise Price; provided,
further, that the Exercise Price will not be reduced below the par value of the Shares, if any. 
 5.10 No
Disqualification. Notwithstanding any other provision in this Plan, no term of this Plan relating to ISOs will be interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify
this Plan under Section 422 of the Code or, without the consent of the Participant, to disqualify any Participant’s ISO under Section 422 of the Code. In no event shall the total number of Shares issued (counting each reissuance of a
Share that was previously issued and then forfeited or repurchased by the Company as a separate issuance) under the Plan upon exercise of ISOs exceed 6,000,000 Shares (adjusted in proportion to any adjustments under Section 2.2 hereof) over the
term of the Plan. 
 6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the Company to sell to an
eligible person Shares that are subject to certain specified restrictions. The Committee will determine to whom an offer will be made, the number of Shares the person may purchase, the Purchase Price, the restrictions to which the Shares will be
subject, and all other terms and conditions of the Restricted Stock Award, subject to the following: 
 6.1 Form of
Restricted Stock Award. All purchases under a Restricted Stock Award made pursuant to this Plan will be evidenced by an Award Agreement (“Restricted Stock Purchase Agreement”) that will be in such form (which need not
be the same for each Participant) as the Committee will from time to time approve, and will comply with and be subject to the terms and conditions of this Plan. The Restricted Stock Award will be accepted by the Participant’s execution and
delivery of the Restricted Stock Purchase Agreement and full payment for the Shares to the Company within thirty (30) days from the date the Restricted Stock Purchase Agreement is delivered to the person. If such person does not execute and
deliver the Restricted Stock Purchase Agreement along with full payment for the Shares to the Company within such thirty (30) days, then the offer will terminate, unless otherwise determined by the Committee. 
 6.2 Purchase Price. The Purchase Price of Shares sold pursuant to a Restricted Stock Award will be determined by the Committee
and will be at least eighty-five percent (85%) of the Fair Market Value of the Shares on the date the Restricted Stock Award is granted or at the time the purchase is consummated, except in the case of a sale to a Ten Percent Stockholder, in
which case the Purchase Price will be one hundred percent (100%) of the Fair Market Value on the date the Restricted Stock Award is granted or at the time the purchase is consummated. Payment of the Purchase Price must be made in accordance
with Section 7 hereof. 
 6.3 Restrictions. Restricted Stock Awards may be subject to the restrictions set
forth in Section 11 hereof or such other restrictions not inconsistent with Section 25102(o) of the California Corporations Code. 
  

 6 








 7. PAYMENT FOR SHARE PURCHASES. 
 7.1 Payment. Payment for Shares purchased pursuant to this Plan may be made in cash (by check) or, where expressly approved for
the Participant by the Committee and where permitted by law: 
 (a) by cancellation of indebtedness of the Company owed to the
Participant; 
 (b) by surrender of shares that: (i) either (A) have been owned by Participant for more than six
(6) months and have been paid for within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares) or (B) were obtained by
Participant in the public market and (ii) are clear of all liens, claims, encumbrances or security interests; 
 (c) by
tender of a full recourse promissory note having such terms as may be approved by the Committee and bearing interest at a rate sufficient to avoid (i) imputation of income under Sections 483 and 1274 of the Code and (ii) variable
accounting treatment under Financial Accounting Standards Board Interpretation No. 44 to APB No. 25; provided, however, that Participants who are not employees or directors of the Company will not be entitled to purchase Shares with a
promissory note unless the note is adequately secured by collateral other than the Shares; provided, further, that the portion of the Exercise Price or Purchase Price, as the case may be, equal to the par value of the Shares must be paid in cash or
other legal consideration permitted by Delaware General Corporation Law; 
 (d) by waiver of compensation due or accrued to the
Participant from the Company for services rendered; 
 (e) with respect only to purchases upon exercise of an Option, and
provided that a public market for the Company’s stock exists: 
 (i) through a “same day sale” commitment from
the Participant and a broker-dealer that is a member of the National Association of Securities Dealers (an “NASD Dealer”) whereby the Participant irrevocably elects to exercise the Option and to sell a portion of the Shares
so purchased sufficient to pay the total Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price directly to the Company; or 
 (ii) through a “margin” commitment from the Participant and an NASD Dealer whereby the Participant irrevocably elects to exercise
the Option and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the total Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of such
Shares to forward the total Exercise Price directly to the Company; or 
 (f) by any combination of the foregoing. 

 

 7 








 7.2 Loan Guarantees. The Committee may, in its sole discretion, elect to
assist the Participant in paying for Shares purchased under this Plan by authorizing a guarantee by the Company of a third-party loan to the Participant. 
 8. WITHHOLDING TAXES. 
 8.1 Withholding Generally. Whenever
Shares are to be issued in satisfaction of Awards granted under this Plan, the Company may require the Participant to remit to the Company an amount sufficient to satisfy federal, state and local withholding tax requirements prior to the delivery of
any certificate or certificates for such Shares. Whenever, under this Plan, payments in satisfaction of Awards are to be made in cash by the Company, such payment will be net of an amount sufficient to satisfy federal, state, and local withholding
tax requirements. 
 8.2 Stock Withholding. When, under applicable tax laws, a Participant incurs tax liability in
connection with the exercise or vesting of any Award that is subject to tax withholding and the Participant is obligated to pay the Company the amount required to be withheld, the Committee may in its sole discretion allow the Participant to satisfy
the minimum withholding tax obligation by electing to have the Company withhold from the Shares to be issued that minimum number of Shares having a Fair Market Value equal to the minimum amount required to be withheld, determined on the date that
the amount of tax to be withheld is to be determined; but in no event will the Company withhold Shares if such withholding would result in adverse accounting consequences to the Company. All elections by a Participant to have Shares withheld for
this purpose will be made in accordance with the requirements established by the Committee for such elections and be in writing in a form acceptable to the Committee. 
 9. PRIVILEGES OF STOCK OWNERSHIP. 
 9.1 Voting and Dividends.
No Participant will have any of the rights of a stockholder with respect to any Shares until the Shares are issued to the Participant. After Shares are issued to the Participant, the Participant will be a stockholder and have all the rights of a
stockholder with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares; provided, that if such Shares are Restricted Stock, then any new, additional or different
securities the Participant may become entitled to receive with respect to such Shares by virtue of a stock dividend, stock split or any other change in the corporate or capital structure of the Company will be subject to the same restrictions as the
Restricted Stock. The Participant will have no right to retain such stock dividends or stock distributions with respect to Unvested Shares that are repurchased pursuant to Section 11 hereof. To the extent required, the Company will comply with
Section 260.140.1 of Title 10 of the California Code of Regulations with respect to the voting rights of Common Stock. 
 9.2 Financial Statements. The Company will provide financial statements to each Participant annually during the period such Participant has Awards outstanding, or as otherwise required under Section 260.140.46 of
Title 10 of the California Code of Regulations. Notwithstanding the foregoing, the Company will not be required to provide such financial statements to Participants when issuance of Awards is limited to key employees whose services in
connection with the Company assure them access to equivalent information. 
  

 8 








 10. TRANSFERABILITY. Except as permitted by the Committee,
Awards granted under this Plan, and any interest therein, will not be transferable or assignable by Participant, other than by will or by the laws of descent and distribution, and, with respect to NQSOs, by instrument to an inter vivos or
testamentary trust in which the options are to be passed to beneficiaries upon the death of the trustor (settlor), or by gift to “immediate family” as that term is defined in 17 C.F.R. 240.16a-1(e), and may not be made subject to
execution, attachment or similar process. During the lifetime of the Participant an Award will be exercisable only by the Participant or Participant’s legal representative and any elections with respect to an Award may be made only by the
Participant or Participant’s legal representative. 
 11. RESTRICTIONS ON SHARES. 
 11.1 Right of First Refusal. At the discretion of the Committee, the Company may reserve to itself and/or its assignee(s) in
the Award Agreement a right of first refusal to purchase all Shares that a Participant (or a subsequent transferee) may propose to transfer to a third party, unless otherwise not permitted by Section 25102(o) of the California Corporations
Code, provided that such right of first refusal terminates upon the Company’s initial public offering of Common Stock pursuant to an effective registration statement filed under the Securities Act. 
 11.2 Right of Repurchase. At the discretion of the Committee, the Company may reserve to itself and/or its assignee(s) in the
Award Agreement a right to repurchase Unvested Shares held by a Participant for cash and/or cancellation of purchase money indebtedness owed to the Company by the Participant following such Participant’s Termination at any time within the later
of ninety (90) days after the Participant’s Termination Date and the date the Participant purchases Shares under the Plan at the Participant’s Exercise Price or Purchase Price, as the case may be, provided that to the extent
Section 25102(o) of the California Corporations Code is intended to apply, unless the Participant is an officer, director or consultant of the Company or of a Parent or Subsidiary of the Company, such right of repurchase lapses at the rate of
no less than twenty percent (20%) per year over five (5) years from: (a) the date of grant of the Option or (b) in the case of Restricted Stock, the date the Participant purchases the Shares. 
 12. CERTIFICATES. All certificates for Shares or other securities delivered under this Plan will be subject to such
stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable federal, state or foreign securities law, or any rules, regulations and other requirements of the SEC
or any stock exchange or automated quotation system upon which the Shares may be listed or quoted. 
 13. ESCROW; PLEDGE
OF SHARES. To enforce any restrictions on a Participant’s Shares set forth in Section 11 hereof, the Committee may require the Participant to deposit all certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in blank, with the Company or an agent designated by the Company to hold in escrow until such restrictions have lapsed or

  

 9 








 
terminated. The Committee may cause a legend or legends referencing such restrictions to be placed on the certificates. Any Participant who is permitted to execute a promissory note as partial or
full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so purchased as collateral to secure the payment of Participant’s obligation to the Company under
the promissory note; provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of such obligation and, in any event, the Company will have full recourse against the Participant under
the promissory note notwithstanding any pledge of the Participant’s Shares or other collateral. In connection with any pledge of the Shares, Participant will be required to execute and deliver a written pledge agreement in such form as the
Committee will from time to time approve. The Shares purchased with the promissory note may be released from the pledge on a pro rata basis as the promissory note is paid. 
 14. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time or from time to time, authorize the Company, with the
consent of the respective Participants, to issue new Awards in exchange for the surrender and cancellation of any or all outstanding Awards. The Committee may at any time buy from a Participant an Award previously granted with payment in cash,
shares of Common Stock of the Company (including Restricted Stock) or other consideration, based on such terms and conditions as the Committee and the Participant may agree. 
 15. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. Although this Plan is intended to be a written compensatory
benefit plan within the meaning of Rule 701 promulgated under the Securities Act, grants may be made pursuant to this plan that do not qualify for exemption under Rule 701 or Section 25102(o) of the California Corporations Code. Any
requirement of this Plan which is required in law only because of Section 25102(o) need not apply if the Committee so provides. An Award will not be effective unless such Award is in compliance with all applicable federal and state securities
laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed or quoted, as they are in effect on the date of grant of the Award and also on
the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or deliver certificates for Shares under this Plan prior to (i) obtaining any approvals from governmental
agencies that the Company determines are necessary or advisable, and/or (ii) compliance with any exemption, completion of any registration or other qualification of such Shares under any state or federal law or ruling of any governmental body
that the Company determines to be necessary or advisable. The Company will be under no obligation to register the Shares with the SEC or to effect compliance with the exemption, registration, qualification or listing requirements of any state
securities laws, stock exchange or automated quotation system, and the Company will have no liability for any inability or failure to do so. 
 16. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted under this Plan will confer or be deemed to confer on any Participant any right to continue in the employ
of, or to continue any other relationship with, the Company or any Parent or Subsidiary of the Company or limit in any way the right of the Company or any Parent or Subsidiary of the Company to terminate Participant’s employment or other
relationship at any time, with or without Cause. 
  

 10 








 17. CORPORATE TRANSACTIONS. 
 17.1 Assumption or Replacement of Awards by Successor or Acquiring Company. In the event of (i) a dissolution or
liquidation of the Company, (ii) any reorganization, consolidation, merger or similar transaction or series of related transactions (each, a “combination transaction”)) in which the Company is a constituent corporation
or is a party if, as a result of such combination transaction, the voting securities of the Company that are outstanding immediately prior to the consummation of such combination transaction (other than any such securities that are held by an
“Acquiring Stockholder”, as defined below) do not represent, or are not converted into, securities of the surviving corporation of such combination transaction (or such surviving corporation’s parent corporation if the surviving
corporation is owned by the parent corporation) that, immediately after the consummation of such combination transaction, together possess at least a majority of the total voting power of all securities of such surviving corporation (or its parent
corporation, if applicable) that are outstanding immediately after the consummation of such combination transaction, including securities of such surviving corporation (or its parent corporation, if applicable) that are held by the Acquiring
Stockholder; or (b) a sale of all or substantially all of the assets of the Company, that is followed by the distribution of the proceeds to the Company’s stockholders, any or all outstanding Awards may be assumed, converted or replaced by
the successor or acquiring corporation (if any), which assumption, conversion or replacement will be binding on all Participants. In the alternative, the successor or acquiring corporation may substitute equivalent Awards or provide substantially
similar consideration to Participants as was provided to stockholders of the Company (after taking into account the existing provisions of the Awards). The successor or acquiring corporation may also substitute by issuing, in place of outstanding
Shares of the Company held by the Participant, substantially similar shares or other property subject to repurchase restrictions and other provisions no less favorable to the Participant than those which applied to such outstanding Shares
immediately prior to such transaction described in this Section 1717.1. For purposes of this Section 17.1, an “Acquiring Stockholder” means a stockholder or stockholders of the Company that (i) merges or
combines with the Company in such combination transaction or (ii) owns or controls a majority of another corporation that merges or combines with the Corporation in such combination transaction. In the event such successor or acquiring
corporation (if any) does not assume, convert, replace or substitute Awards, as provided above, pursuant to a transaction described in this Section 1717.1, then notwithstanding any other provision in this Plan to the contrary, the vesting of
such Awards will accelerate and the Options will become exercisable in full prior to the consummation of such event at such times and on such conditions as the Committee determines, and if such Options are not exercised prior to the consummation of
the corporate transaction, they shall terminate in accordance with the provisions of this Plan. 
 17.2 Other Treatment of
Awards. Subject to any greater rights granted to Participants under the foregoing provisions of this Section 17, in the event of the occurrence of any transaction described in Section 17.1 hereof, any outstanding Awards will be
treated as provided in the applicable agreement or plan of reorganization, merger, consolidation, dissolution, liquidation or sale of assets. 
  

 11 








 17.3 Assumption of Awards by the Company. The Company, from time to time, also
may substitute or assume outstanding awards granted by another company, whether in connection with an acquisition of such other company or otherwise, by either (i) granting an Award under this Plan in substitution of such other company’s
award or (ii) assuming such award as if it had been granted under this Plan if the terms of such assumed award could be applied to an Award granted under this Plan. Such substitution or assumption will be permissible if the holder of the
substituted or assumed award would have been eligible to be granted an Award under this Plan if the other company had applied the rules of this Plan to such grant. In the event the Company assumes an award granted by another company, the terms and
conditions of such award will remain unchanged (except that the exercise price and the number and nature of shares issuable upon exercise of any such option will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event
the Company elects to grant a new Option rather than assuming an existing option, such new Option may be granted with a similarly adjusted Exercise Price. 
 18. ADOPTION AND STOCKHOLDER APPROVAL. This Plan will become effective on the date that it is adopted by the Board (the “Effective Date”). This Plan
will be approved by the stockholders of the Company (excluding Shares issued pursuant to this Plan), consistent with applicable laws, within twelve (12) months before or after the Effective Date. Upon the Effective Date, the Board may grant
Awards pursuant to this Plan; provided, however, that: (i) no Option may be exercised prior to initial stockholder approval of this Plan; (ii) no Option granted pursuant to an increase in the number of Shares approved by the Board shall be
exercised prior to the time such increase has been approved by the stockholders of the Company; (iii) in the event that initial stockholder approval is not obtained within the time period provided herein, all Awards granted hereunder shall be
canceled, any Shares issued pursuant to any Award shall be canceled and any purchase of Shares issued hereunder shall be rescinded; and (iv) Awards granted pursuant to an increase in the number of Shares approved by the Board which increase is
not timely approved by stockholders shall be canceled, any Shares issued pursuant to any such Awards shall be canceled, and any purchase of Shares subject to any such Award shall be rescinded. 
 19. TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided herein, this Plan will terminate ten
(10) years from the Effective Date or, if earlier, the date of stockholder approval. This Plan and all agreements hereunder shall be governed by and construed in accordance with the laws of the State of California. 
 20. AMENDMENT OR TERMINATION OF PLAN. Subject to Section 5.9 hereof, the Board may at any time terminate or amend
this Plan in any respect, including without limitation amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan; provided, however, that the Board will not, without the approval of the stockholders of the Company,
amend this Plan in any manner that requires such stockholder approval pursuant to Section 25102(o) of the California Corporations Code or the Code or the regulations promulgated thereunder as such provisions apply to ISO plans. 
 21. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by the Board, the submission of this Plan to
the stockholders of the Company for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem desirable, including, without
limitation, the granting of stock options and other equity awards otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific cases.
