(ix)      to adjust the vesting of an Option held by an Employee or Consultant as a result of a change in
the terms or conditions under which such person is providing services to the Company;

 5.       Eligibility. 

 (a)      Recipients of Grants. Nonstatutory Stock Options may be granted to Employees,
Consultants and Directors. Incentive Stock Options may be granted only to Employees, provided that Employees of Affiliates shall not be eligible to receive Incentive Stock Options. 

 (b)      Type of Option. Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. 
  (c)      ISO
$100,000 Limitation. Notwithstanding any designation under Section 5(b), to the extent that the aggregate Fair Market Value of Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time
by any Optionee during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock
Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option. 

 (d)      No Employment Rights. The Plan shall not confer upon any Participant any
right with respect to continuation of an employment or consulting relationship with the Company, nor shall it interfere in any way with such Participant’s right or the Company’s right to terminate the employment or consulting relationship
at any time, for any reason. 
 6.      Term of Plan. The Plan shall become
effective upon its adoption by the Board of Directors. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 15 of the Plan. 

7.      Term of Option. The term of each Option shall be the term stated in the Option
Agreement; provided that the term shall be no more than ten years from the date of grant thereof or such shorter term as may be provided in the Option Agreement and provided further that, in the case of an Incentive Stock Option granted to a
person who at the time of such grant is a Ten Percent Holder, the term of the Option shall be five years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 

8.      [Reserved.] 
 9.      Option Exercise Price and Consideration. 
  (a)      Exercise Price. The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined
by the Administrator and set forth in the Option Agreement, but shall be subject to the following: 

   (i)      In the case of an Incentive Stock Option 

  
 -7-

  (A)      granted to an Employee who at the time of
grant is a Ten Percent Holder, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant; or 
  (B)      granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. 

 (ii)      In the case of a Nonstatutory Stock Option 

 (A)      granted on any date on which the Common Stock is not a Listed Security to a person who is
at the time of grant is a Ten Percent Holder, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as is
determined by the Administrator; 
  (B)      granted on any date on which the Common Stock
is not a Listed Security to any other eligible person, the per Share exercise price shall be no less than 85% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as
is determined by the Administrator; or 
  (C)      granted on any date on which the Common
Stock is a Listed Security to any eligible person, the per share Exercise Price shall be such price as determined by the Administrator provided that if such eligible person is, at the time of the grant of such Option, a Named Executive of the
Company, the per share Exercise Price shall be no less than 100% of the Fair Market Value on the date of grant if such Option is intended to qualify as performance-based compensation under Section 162(m) of the Code. 

 (iii)      Notwithstanding the foregoing, Options may be granted with a per Share exercise price
other than as required above pursuant to a merger or other corporate transaction. 

(b)      Permissible Consideration.  The consideration to be paid for the Shares
to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant) and may consist entirely of (1) cash;
(2) check; (3) subject to any requirements of the Applicable Laws (including without limitation Section 153 of the Delaware General Corporation Law), delivery of Optionee’s promissory note having such recourse, interest, security
and redemption provisions as the Administrator determines to be appropriate after taking into account the potential accounting consequences of permitting an Optionee to deliver a promissory note; (4) cancellation of indebtedness; (5) other
Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option is exercised, provided that in the case of Shares acquired, directly or indirectly, from the Company, such
Shares must have been owned by the Optionee for more than six months on the date of surrender (or such other period as may be required to avoid the Company’s incurring an adverse accounting charge); (6) if, as of the date of exercise of an
Option the Company then is permitting employees to engage in a “same-day sale” cashless brokered exercise program 

  
 -8-

 
involving one or more brokers, through such a program that complies with the Applicable Laws (including without limitation the requirements of Regulation T and other applicable regulations
promulgated by the Federal Reserve Board) and that ensures prompt delivery to the company of the amount required to pay the exercise price and any applicable withholding taxes; or (7) any combination of the foregoing methods of payment. In
making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company and the Administrator may, in its sole discretion, refuse to
accept a particular form of consideration at the time of any Option exercise. 

10.      Exercise of Option. 

  (a)    General. 
   (i)      Exercisability. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the
Administrator, consistent with the term of the Plan and reflected in the Option Agreement, including vesting requirements and/or performance criteria with respect to the Company and/or the Optionee; provided however that, if required under
Applicable Laws, the Option (or Shares issued upon exercise of the Option) shall comply with the requirements of Section 260.140.41(f) and (k) of the Rules of the California Corporations Commissioner. 

  (ii)      Leave of Absence. The Administrator shall have the discretion to
determine whether and to what extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such unpaid leave (unless
otherwise required by the Applicable Laws). In the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon a Participant’s returning from military leave (under conditions that would entitle him
or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have applied had the Participant continued to
provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 
   (iii)      Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The Administrator may require that an Option be
exercised as to a minimum number of Shares, provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then exercisable. 

  (iv)      Procedures for and Results of Exercise. An Option shall be deemed
exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to which the
Option is exercised. Full payment may, as authorized by the Administrator, consist of any consideration and method of payment allowable under Section 9(b) of the Plan, provided that the Administrator may, in its sole discretion, refuse to
accept any form of consideration at the time of any Option exercise. 

  
 -9-

 Exercise of an Option in any manner shall result in a decrease in the number of Shares that
thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
  (v)      Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 14 of the Plan. 
 (b)      Termination of Employment or Consulting Relationship. Except as otherwise set forth in this Section 10(b), the Administrator shall establish and
set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain exercisable, if at all, following termination of an Optionee’s Continuous Service Status, which provisions may be waived or modified by the
Administrator at any time. Unless the Administrator otherwise provides in the Option Agreement, to the extent that the Optionee is not vested in Optioned Stock at the date of termination of his or her Continuous Service Status, or if the Optionee
(or other person entitled to exercise the Option) does not exercise the Option to the extent so entitled within the time specified in the Option Agreement or below (as applicable), the Option shall terminate and the Optioned Stock underlying the
unexercised portion of the Option shall revert to the Plan. In no event may any Option be exercised after the expiration of the Option term as set forth in the Option Agreement (and subject to Section 7). 

The following provisions (1) shall apply to the extent an Option Agreement does not specify the terms and conditions upon which an
Option shall terminate upon termination of an Optionee’s Continuous Service Status, and (2) establish the minimum post-termination exercise periods that may be set forth in an Option Agreement: 

(i)        Termination other than Upon Disability or Death. In the event of
termination of Optionee’s Continuous Service Status other than under the circumstances set forth in subsections (ii) and (iii) below, such Optionee may exercise an Option for 60 days following such termination to the extent the
Optionee was vested in the Optioned Stock as of the date of such termination. No termination shall be deemed to occur and this Section 10(b)(i) shall not apply if (i) the Optionee is a Consultant who becomes an Employee, or
(ii) the Optionee is an Employee who becomes a Consultant. 

(ii)       Disability of Optionee. In the event of termination of an Optionee’s
Continuous Service Status as a result of his or her disability (including a disability within the meaning of Section 22(e)(3) of the Code), such Optionee may exercise an Option at any time within six (6) months following such termination
to the extent the Optionee was vested in the Optioned Stock as of the date of such termination. 

(iii)      Death of Optionee. In the event of the death of an Optionee during the period of
Continuous Service Status since the date of grant of the Option, or within thirty (30) days following termination of Optionee’s Continuous Service Status, the Option may 

  
 -10-

 
be exercised by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance at any time within twelve (12) months following the date of
death, but only to the extent the Optionee was vested in the Optioned Stock as of the date of death or, if earlier, the date the Optionee’s Continuous Service Status terminated. 

(c)      Buyout Provisions. The Administrator may at any time offer to buy out for a payment
in cash or Shares an Option previously granted under the Plan based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made. 

11.    Taxes. 
 (a)      As a condition of the grant, vesting or exercise of an Option granted under the Plan, the Participant (or in the case of the Participant’s death, the person
exercising the Option) shall make such arrangements as the Administrator may require for the satisfaction of any applicable federal, state, local or foreign withholding tax obligations that may arise in connection with such grant, vesting or
exercise of the Option or the issuance of Shares. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. If the Administrator allows the withholding or surrender of Shares to satisfy a
Participant’s tax withholding obligations under this Section 11 (whether pursuant to Section 11(c), (d) or (e), or otherwise), the Administrator shall not allow Shares to be withheld in an amount that exceeds the minimum
statutory withholding rates for federal and state tax purposes, including payroll taxes. 

(b)      In the case of an Employee and in the absence of any other arrangement, the Employee shall be
deemed to have directed the Company to withhold or collect from his or her compensation an amount sufficient to satisfy such tax obligations from the next payroll payment otherwise payable after the date of an exercise of the Option. 

(c)      This Section 11(c) shall apply only after the date, if any, upon which the Common Stock
becomes a Listed Security. In the case of Participant other than an Employee (or in the case of an Employee where the next payroll payment is not sufficient to satisfy such tax obligations, with respect to any remaining tax obligations), in the
absence of any other arrangement and to the extent permitted under the Applicable Laws, the Participant shall be deemed to have elected to have the Company withhold from the Shares to be issued upon exercise of the Option that number of Shares
having a Fair Market Value determined as of the applicable Tax Date (as defined below) equal to the amount required to be withheld. For purposes of this Section 11, the Fair Market Value of the Shares to be withheld shall be determined on the
date that the amount of tax to be withheld is to be determined under the Applicable Laws (the “Tax Date”). 

(d)      If permitted by the Administrator, in its discretion, a Participant may satisfy his or her tax
withholding obligations upon exercise of an Option by surrendering to the Company Shares that have a Fair Market Value determined as of the applicable Tax Date equal to the amount required to be withheld. In the case of shares previously acquired
from the Company that are surrendered under this Section 11(d), such Shares must have been owned by 

  
 -11-

 
the Participant for more than six (6) months on the date of surrender (or such other period of time as is required for the Company to avoid adverse accounting charges). 

(e)      Any election or deemed election by a Participant to have Shares withheld to satisfy tax
withholding obligations under Section 11(c) or (d) above shall be irrevocable as to the particular Shares as to which the election is made and shall be subject to the consent or disapproval of the Administrator. Any election by a
Participant under Section 11(d) above must be made on or prior to the applicable Tax Date. 

(f)      In the event an election to have Shares withheld is made by a Participant and the Tax Date is
deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Participant shall receive the full number of Shares with respect to which the Option is exercised but such Participant shall be
unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 

12.    Non-Transferability of Options. 

(a)      General. Except as set forth in this Section 12, Options may not be sold,
pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution. The designation of a beneficiary by an Optionee will not constitute a transfer. An Option may be exercised,
during the lifetime of the holder of an Option, only by such holder or a transferee permitted by this Section 12. 

(b)      Limited Transferability Rights. Notwithstanding anything else in this
Section 12, the Administrator may in its discretion grant Nonstatutory Stock Options that may be transferred 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 or pursuant to domestic relations orders to “Immediate Family Members” (as defined below) of the Optionee. “Immediate Family” means any child, stepchild, grandchild, parent, stepparent,
grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law (including adoptive relationships), a trust in which these persons have more than fifty percent
of the beneficial interest, a foundation in which these persons (or the Optionee) control the management of assets, and any other entity in which these persons (or the Optionee) own more than fifty percent of the voting interests. 

13.    Adjustments Upon Changes in Capitalization, Merger or Certain Other Transactions. 

(a)      Changes in Capitalization. Subject to any action required under Applicable Laws by
the stockholders of the Company, the number of Shares of Common Stock covered by each outstanding Option and the number of Shares of Common Stock that have been authorized for issuance under the Plan but as to which no Options have yet been granted
or that have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per Share of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number
of issued Shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination, recapitalization or 

  
 -12-

 
reclassification of the Common Stock, or any other increase or decrease in the number of issued Shares of Common Stock effected without receipt of consideration by the Company; provided, however,
that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be
final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be
made with respect to, the number or price of Shares of Common Stock subject to an Option. 

 (b)      Dissolution or Liquidation. In the event of the dissolution or liquidation of
the Company, each Option will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 
  (c)      Corporate Transactions; Change of Control. In the event of a Corporate Transaction, each outstanding Option shall be assumed or an equivalent
option or right shall be substituted by the successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”), and the Successor Corporation shall succeed to any repurchase rights of the
Company with respect to shares issued upon exercise of an award, unless the Successor Corporation does not agree to assume the outstanding Options or to substitute equivalent options or rights, in which case the Options shall terminate upon the
consummation of the Corporate Transaction. 
  In the event of a Corporate Transaction that is a Change of
Control, unless otherwise specified in an Option Agreement, the following provisions shall govern: 

   (i)      If the Successor Corporation does not agree to assume the
outstanding Options or to substitute equivalent options or rights in connection with the Change of Control, in the case of an award held by any Participant who, immediately prior to the Change of Control is either (A) an officer of the Company
or Photon (meaning that the Participant holds the title of at least Vice President of the Company or the equivalent at Photon), (B) an employee of the Company or Photon at the employee-director level (as determined by the Administrator), or
(C) a non-employee member of the Board (or the board of directors of Photon), the Options in the award shall accelerate and become exercisable (and Company repurchase rights with respect to shares issued upon exercise of the award shall lapse)
immediately prior to the Change of Control as to that number of shares that would otherwise have vested and been exercisable (or with respect to which the Company repurchase right would have lapsed) as of the date that is twelve (12) months
after the date of the Change of Control, assuming the Participant remained in Continuous Service Status for its twelve month period, and upon the consummation of the Change of Control, all Options shall terminate. 

   (ii)      If the Successor Corporation does agree to assume the
outstanding Options or to substitute equivalent options or rights in connection with the Change of Control, in the case of an award held by any Participant who, immediately prior to the Change of Control is either (A) an officer of the Company
or Photon (meaning that the Participant holds the title of at least Vice President of the Company or the equivalent at Photon), (B) an employee of the 

  
 -13-

 
Company or Photon at the employee-director level (as determined by the Administrator), or (C) a non-employee member of the Board (or the board of directors of Photon), in the event of the
Involuntary Termination of the Participant in connection with or within twelve (12) months following consummation of the Corporate Transaction, then, effective immediately prior to such Involuntary Termination, any assumed or substituted award
held by the Participant at the time of such Involuntary Termination shall accelerate and become exercisable as to that number of Shares that would otherwise have vested and been exercisable as of the date that is twelve (12) months after the
date of termination, and any repurchase right applicable to any Shares subject to the award shall lapse as to that number of Shares as to which the repurchase right would otherwise have lapsed as of the date that is twelve (12) months after the
date of termination, in each case assuming the Participant remained in Continuous Service Status for the twelve-month period. 
  Notwithstanding the foregoing, in connection with or prior to a Change of Control, without consent of a Participant, the Board may determine that additional Shares shall vest and become exercisable
in the event of a Change of Control or Involuntary Termination in connection with or following a Change of Control. 

 For purposes of this Section 13(c), an Option shall be considered assumed, without limitation, if, at the time of issuance of
the stock or other consideration upon a Corporate Transaction or Change of Control, as the case may be, each holder of an Option would be entitled to receive upon exercise of the award the same number and kind of shares of stock or the same amount
of property, cash or securities as the holder would have been entitled to receive upon the occurrence of the Corporate Transaction if the holder had been, immediately prior to such transaction, the holder of the number of Shares of Common Stock
covered by the award at such time (after giving effect to any adjustments in the number of Shares covered by the Option as provided for in this Section 13); provided however that if the consideration received in the Corporate Transaction is not
solely common stock of the Successor Corporation, the Administrator may, with the consent of the Successor Corporation, provide for the consideration to be received upon exercise of the award to be solely common stock of the Successor Corporation
equal to the Fair Market Value of the per Share consideration received by holders of Common Stock in the Corporate Transaction. 
  (d)      Certain Distributions. In the event of any distribution to the Company’s stockholders of securities of any other entity or other assets
(other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Administrator may, in its discretion, appropriately adjust the price per Share of Common Stock covered by each outstanding Option to
reflect the effect of such distribution. 
 14.      Time of Granting Options. The
date of grant of an Option shall, for all purposes, be the date on which the Administrator makes the determination granting such Option, or such other date as is determined by the Administrator, provided that in the case of any Incentive Stock
Option, the grant date shall be the later of the date on which the Administrator makes the determination granting such Incentive Stock Option or the date of commencement of the Optionee’s employment relationship with the Company. Notice of the
determination shall be 

  
 -14-

 
given to each Employee or Consultant to whom an Option is so granted within a reasonable time after the date of such grant. 

15.      Amendment and Termination of the Plan. 

 (a)      Authority to Amend or Terminate. The Board may at any time amend, alter,
suspend or discontinue the Plan, but no amendment, alteration, suspension or discontinuation (other than an adjustment pursuant to Section 13 above) shall be made that would materially and adversely affect the rights of any Optionee under any
outstanding grant, without his or her consent. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as
required. 
  (b)      Effect of Amendment or Termination. Except as to
amendments which the Administrator has the authority under the Plan to make unilaterally, no amendment or termination of the Plan shall materially and adversely affect Options already granted, unless mutually agreed otherwise between the Optionee
and the Administrator, which agreement must be in writing and signed by the Optionee or holder and the Company. 

16.      Conditions Upon Issuance of Shares. Notwithstanding any other provision of the Plan
or any agreement entered into by the Company pursuant to the Plan, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such issuance or delivery would comply with the
Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. As a condition to the exercise of an Option, the Company may require the person exercising the award to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by law. Shares issued upon
exercise of Options granted prior to the date on which the Common Stock becomes a Listed Security shall be subject to a right of first refusal in favor of the Company pursuant to which the Participant will be required to offer Shares to the Company
before selling or transferring them to any third party on such terms and subject to such conditions as is reflected in the applicable Option Agreement. 
 17.      Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan. 
 18.      Agreements. Options
shall be evidenced by Option Agreements in such form(s) as the Administrator shall from time to time approve. 

19.      Stockholder Approval. If required by the Applicable Laws, continuance of the Plan
shall be subject to approval by the stockholders of the Company within twelve (12) months before or after the date the Plan is adopted. Such stockholder approval shall be obtained in the manner and to the degree required under the Applicable
Laws. 

  
 -15-

 20.      Information and Documents to Optionees and
Purchasers. Prior to the date, if any, upon which the Common Stock becomes a Listed Security and if required by the Applicable Laws, the Company shall provide financial statements at least annually to each Optionee and to each individual who
acquired Shares pursuant to the Plan, during the period such Optionee or purchaser has one or more Options outstanding, and in the case of an individual who acquired Shares pursuant to the Plan, during the period such individual owns such Shares.
The Company shall not be required to provide such information if the issuance of Options under the Plan is limited to key employees whose duties in connection with the Company assure their access to equivalent information.

 NEOPHOTONICS CORPORATION 

2004 STOCK OPTION PLAN 
 STOCK OPTION AGREEMENT 

1.      Grant of Option. NeoPhotonics Corporation, a Delaware corporation (the
“Company”), hereby grants to «Optionee_» (“Optionee”), an option (the “Option”) to purchase the total number of shares of Common Stock (the “Shares”) set forth in
the Notice of Stock Option Grant (the “Notice”), at the exercise price per Share set forth in the Notice (the “Exercise Price”) subject to the terms, definitions and provisions of the NeoPhotonics Corporation 2004
Stock Option Plan (the “Plan”) adopted by the Company, which is incorporated in this Agreement by reference. Unless otherwise defined in this Agreement, the terms used in this Agreement shall have the meanings defined in the Plan.

 2.      Designation of Option. This Option is intended to be an Incentive Stock
Option as defined in Section 422 of the Code only to the extent so designated in the Notice, and to the extent it is not so designated or to the extent the Option does not qualify as an Incentive Stock Option, it is intended to be a
Nonstatutory Stock Option. 
 Notwithstanding the above, if designated as an Incentive Stock Option, in the event that the
Shares subject to this Option (and all other Incentive Stock Options granted to Optionee by the Company or any Parent or Subsidiary, including under other plans of the Company) that first become exercisable in any calendar year have an aggregate
fair market value (determined for each Share as of the date of grant of the option covering such Share) in excess of $100,000, the Shares in excess of $100,000 shall be treated as subject to a Nonstatutory Stock Option, in accordance with
Section 5(c) of the Plan. 
 3.      Exercise of Option. This Option shall be
exercisable during its term in accordance with the Vesting/Exercise Schedule set out in the Notice and with the provisions of Section 10 of the Plan as follows: 
  (a)      Right to Exercise. 

  (i)      This Option may not be exercised for a fraction of a share. 

  (ii)     In the event of Optionee’s death, disability or other termination of employment, the
exercisability of the Option is governed by Section 5 below, subject to the limitations contained in this Section 3. 

  (iii)    In no event may this Option be exercised after the Expiration Date of the Option as set forth
in the Notice. 

 (b)      Method of Exercise. 

 (i)      This Option shall be exercisable by execution and delivery of the Early Exercise Notice and
Restricted Stock Purchase Agreement attached hereto as Exhibit A, [the Exercise Notice and Restricted Stock Purchase Agreement attached hereto as Exhibit B,] or any other form of written notice approved for such purpose by the
Company which shall state Optionee’s election to exercise the Option, the number of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect
to such Shares as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by Optionee and shall be delivered to the Company by such means as are determined by the Plan Administrator in its
discretion to constitute adequate delivery. The written notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price.

  (ii)     As a condition to the exercise of this Option and as further set forth in
Section 12 of the Plan, Optionee agrees to make adequate provision for federal, state or other tax withholding obligations, if any, which arise upon the vesting or exercise of the Option, or disposition of Shares, whether by withholding, direct
payment to the Company, or otherwise. 
  (iii)    The Company is not obligated, and will have no
liability for failure, to issue or deliver any Shares upon exercise of the Option unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. This
Option may not be exercised until such time as the Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation
of any applicable federal or state securities or other law or regulation, including any rule under Part 221 of Title 12 of the Code of Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require Optionee to make any representation and warranty to the Company as may be required by the Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on
the date on which the Option is exercised with respect to such Shares. 
 4.      Method of
Payment. Payment of the Exercise Price shall be by any of the following, or a combination of the following, at the election of Optionee: 
 (a)      cash or check; 

(b)      cancellation of indebtedness; 

(c)      prior to the date, if any, upon which the Common Stock becomes a Listed Security, by surrender of
other shares of Common Stock of the Company that have an aggregate Fair Market Value on the date of surrender equal to the Exercise Price of the Shares as to which the Option is being exercised. In the case of shares acquired directly or indirectly
from the Company, such shares must have been owned by Optionee for more than six (6) months on the 

  
 -2-

 
date of surrender (or such other period of time as is necessary to avoid the Company’s incurring adverse accounting charges); or 

(d)      following the date, if any, upon which the Common Stock is a Listed Security, and if the Company
is at such time permitting “same day sale” cashless brokered exercises, delivery of a properly executed exercise notice together with irrevocable instructions to a broker participating in such cashless brokered exercise program to deliver
promptly to the Company the amount required to pay the exercise price (and applicable withholding taxes). 

5.      Termination of Relationship. Following the date of termination of Optionee’s
Continuous Service Status for any reason (the “Termination Date”), Optionee may exercise the Option only as set forth in the Notice and this Section 5. To the extent that Optionee is not entitled to exercise this Option as of
the Termination Date, or if Optionee does not exercise this Option within the Termination Period set forth in the Notice or the termination periods set forth below, the Option shall terminate in its entirety. In no event, may any Option be exercised
after the Expiration Date of the Option as set forth in the Notice. 

(a)      Termination. In the event of termination of Optionee’s Continuous Service
Status other than as a result of Optionee’s disability or death or for Cause (as defined in the Plan), Optionee may, to the extent Optionee is vested in the Option Shares at the date of such termination (the “Termination
Date”), exercise this Option during the Termination Period set forth in the Notice. 

(b)      Other Terminations. In connection with any termination other than a termination
covered by Section 5(a), Optionee may exercise the Option only as described below: 

  (i)      Termination upon Disability of Optionee. In the event of termination of
Optionee’s Continuous Service Status as a result of Optionee’s disability, Optionee may, but only within six months from the Termination Date, exercise this Option to the extent Optionee was vested in the Option Shares as of such
Termination Date. 
   (ii)     Death of Optionee. In the event of the death
of Optionee (a) during the term of this Option and while an Employee or Consultant of the Company and having been in Continuous Service Status since the date of grant of the Option, or (b) within thirty (30) days after Optionee’s
Termination Date, the Option may be exercised at any time within twelve months following the date of death by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent
Optionee was vested in the Option as of the Termination Date. 
 6.      Non-Transferability
of Option. Except as otherwise set forth in the Notice, this Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by him or
her. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and assigns of Optionee. 

  
 -3-

 7.      Tax Consequences. Below is a brief
summary as of the date of this Option of certain of the federal tax consequences of exercise of this Option and disposition of the Shares under the laws in effect as of the Date of Grant. THIS SUMMARY IS INCOMPLETE, AND THE TAX LAWS AND REGULATIONS
ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 

(a)      Incentive Stock Option. 

 (i)      Tax Treatment upon Exercise and Sale of Shares. If this Option qualifies as
an Incentive Stock Option, there will be no regular federal income tax liability upon the exercise of the Option, although the excess, if any, of the fair market value of the Shares on the date of exercise over the Exercise Price will be treated as
an adjustment to the alternative minimum tax for federal tax purposes and may subject Optionee to the alternative minimum tax in the year of exercise. If Shares issued upon exercise of an Incentive Stock Option are held for at least one year after
exercise and are disposed of at least two years after the Option grant date, any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal income tax purposes. If Shares issued upon exercise of an
Incentive Stock Option are disposed of within such one-year period or within two years after the Option grant date, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the
difference between the Exercise Price and the lesser of (i) the fair market value of the Shares on the date of exercise, or (ii) the sale price of the Shares. 
  (ii)     Notice of Disqualifying Dispositions. With respect to any Shares issued upon exercise of an Incentive Stock Option, if Optionee sells or otherwise
disposes of such Shares on or before the later of (i) the date two years after the Option grant date, or (ii) the date one year after the date of exercise, Optionee shall immediately notify the Company in writing of such disposition.
Optionee acknowledges and agrees that he or she may be subject to income tax withholding by the Company on the compensation income recognized by Optionee from the early disposition by payment in cash or out of the current earnings paid to Optionee.

 (b)      Nonstatutory Stock Option. If this Option does not qualify as an
Incentive Stock Option, there may be a regular federal (and state) income tax liability upon the exercise of the Option. Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if
any, of the fair market value of the Shares on the date of exercise over the Exercise Price. If Optionee is an Employee, the Company will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. If Shares issued upon exercise of a Nonstatutory Stock Option are held for at least one year, any gain realized on disposition of the Shares will
be treated as long-term capital gain for federal income tax purposes. 
 8.      Lock-Up
Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Optionee hereby agrees not to
sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of 

  
 -4-

 
the Company however and whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such
period of time (not to exceed 180 days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the
time of the public offering. 
 9.        Effect of Agreement. Optionee
acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof (and has had an opportunity to consult counsel regarding the Option terms), and hereby accepts this Option and agrees to be
bound by its contractual terms as set forth herein and in the Plan. Optionee hereby agrees to accept as binding, conclusive and final all decisions and interpretations of the Plan Administrator regarding any questions relating to the Option. In the
event of a conflict between the terms and provisions of the Plan and the terms and provisions of the Notice and this Agreement, the Plan terms and provisions shall prevail. The Option, including the Plan, constitutes the entire agreement between
Optionee and the Company on the subject matter hereof and supersedes all proposals, written or oral, and all other communications between the parties relating to such subject matter.

 EXHIBIT A 
 NEOPHOTONICS CORPORATION 
 2004 STOCK OPTION PLAN 

[EARLY] EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE 

AGREEMENT 
 This Agreement (“Agreement”) is made as of             , by and between NeoPhotonics Corporation, a Delaware corporation
(the “Company”), and «Optionee_» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the 2004 Stock Option
Plan. 
 1.      Exercise of Option. Subject to the terms and conditions hereof,
Purchaser hereby elects to exercise his or her [vested] option to purchase              shares of the Common Stock (the “Shares”) of the Company under and
pursuant to the Company’s 2004 Stock Option Plan (the “Plan”) and the Stock Option Agreement granted              (the “Option
Agreement”). [Of these Shares, Purchaser has elected to purchase                      of those Shares which have become vested as of
the date hereof under the Vesting Schedule set forth in the Notice of Stock Option Grant (the “Vested Shares”) and
                     Shares which have not yet vested under such Vesting Schedule (the “Unvested Shares”). The purchase price
for the Shares shall be $ per Share for a total purchase price of
$                                . The term “Shares” refers to
the purchased Shares and all securities received in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares.] 
 2.      [Time and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the provisions of Section 3(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be purchased by Purchaser
(which shall be issued in Purchaser’s name) against payment of the exercise price therefor by Purchaser by any method listed in Section 4 of the Option Agreement. 
 3.      Limitations on Transfer. In addition to any other limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or
dispose of any interest in the Shares while the Shares are subject to the Company’s Repurchase Option (as defined below). After any Shares have been released from such Repurchase Option, Purchaser shall not assign, encumber or dispose of any
interest in such Shares except in compliance with the provisions below and applicable securities laws. 

(a)      Repurchase Option. 

  (i)      In the event of the voluntary or involuntary termination of Purchaser’s
employment or consulting relationship with the Company for any reason (including 

 
death or disability), with or without cause, the Company shall upon the date of such termination (the “Termination Date”) have an irrevocable, exclusive option (the
“Repurchase Option”) for a period of 90 days from such date to repurchase all or any portion of the Shares held by Purchaser as of the Termination Date which have not yet been released from the Company’s Repurchase Option at
the original purchase price per Share specified in Section 1 (adjusted for any stock splits, stock dividends and the like). 
  (ii)     Unless the Company notifies Purchaser within 90 days from the date of termination of Purchaser’s employment or consulting relationship that it does not intend
to exercise its Repurchase Option with respect to some or all of the Shares, the Repurchase Option shall be deemed automatically exercised by the Company as of the 90th day following such termination, provided that the Company may notify Purchaser
that it is exercising its Repurchase Option as of a date prior to such 90th day. Unless Purchaser is otherwise notified by the Company pursuant to the preceding sentence that the Company does not intend to exercise its Repurchase Option as to some
or all of the Shares to which it applies at the time of termination, execution of this Agreement by Purchaser constitutes written notice to Purchaser of the Company’s intention to exercise its Repurchase Option with respect to all Shares to
which such Repurchase Option applies. The Company, at its choice, may satisfy its payment obligation to Purchaser with respect to exercise of the Repurchase Option by either (A) delivering a check to Purchaser in the amount of the purchase
price for the Shares being repurchased, or (B) in the event Purchaser is indebted to the Company, canceling an amount of such indebtedness equal to the purchase price for the Shares being repurchased, or (C) by a combination of
(A) and (B) so that the combined payment and cancellation of indebtedness equals such purchase price. In the event of any deemed automatic exercise of the Repurchase Option pursuant to this Section 3(a)(ii) in which Purchaser is
indebted to the Company, such indebtedness equal to the purchase price of the Shares being repurchased shall be deemed automatically canceled as of the 90th day following termination of Purchaser’s employment or consulting relationship unless
the Company otherwise satisfies its payment obligations. As a result of any repurchase of Shares pursuant to this Section 3(a), the Company shall become the legal and beneficial owner of the Shares being repurchased and shall have all rights
and interest therein or related thereto, and the Company shall have the right to transfer to its own name the number of Shares being repurchased by the Company, without further action by Purchaser. 

 (iii)    One hundred percent (100%) of the Shares shall initially be subject to the Repurchase Option.
The Unvested Shares shall be released from the Repurchase Option in accordance with the Vesting Schedule set forth in the Notice of Stock Option Grant until all Shares are released from the Repurchase Option. Fractional shares shall be rounded to
the nearest whole share. 
 (b)      Right of First Refusal. Before any Shares held
by Purchaser or any transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have
a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section 3(b) (the “Right of First Refusal”). 

  
 -2-

 (i)        Notice of Proposed
Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each
proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder
shall offer the Shares at the same price (the “Offered Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 

(ii)       Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (iii) below. 

(iii)      Purchase Price. The purchase price (“Purchase Price”) for the
Shares purchased by the Company or its assignee(s) under this Section 3(b) shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by
the Board of Directors of the Company in good faith. 
 (iv)      Payment. Payment
of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30 days after receipt of the Notice
or in the manner and at the times set forth in the Notice. 
 (v)      Holder’s Right
to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 3(b), then the Holder may sell or otherwise
transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 60 days after the date of the Notice and provided further that any such sale or other
transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the
Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the
Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (vi)      Exception for Certain Family Transfers. Anything to the contrary contained in this Section 3(b) notwithstanding, the transfer of any or all of
the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of Purchaser’s Immediate Family shall be exempt from the provisions of this
Section 3(b). “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so
transferred subject to the provisions of this Section, 

  
 -3-

 
and there shall be no further transfer of such Shares except in accordance with the terms of this Section 3. 
 (c)    Involuntary Transfer. 

(i)        Company’s Right to Purchase upon Involuntary Transfer. In the
event, at any time after the date of this Agreement, of any transfer by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above) of all or a
portion of the Shares by the record holder thereof, the Company shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement or the Fair Market Value of the Shares
on the date of transfer. Upon such a transfer, the person acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty
(30) days following receipt by the Company of written notice by the person acquiring the Shares. 

(ii)        Price for Involuntary Transfer. With respect to any stock to be
transferred pursuant to Section 3(c)(i), the price per Share shall be a price set by the Board of Directors of the Company that will reflect the current value of the stock in terms of present earnings and future prospects of the Company. The
Company shall notify Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the
valuation as determined by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne
equally by the Company and the Purchaser. 
 (d)    Assignment. The right of the Company to
purchase any part of the Shares may be assigned in whole or in part to any shareholder or shareholders of the Company or other persons or organizations. 
 (e)    Restrictions Binding on Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interest subject to the provisions of
this Agreement, including, insofar as applicable, the Repurchase Option. In the event of any purchase by the Company hereunder where the Shares or interest are held by a transferee, the transferee shall be obligated, if requested by the Company, to
transfer the Shares or interest to the Purchaser for consideration equal to the amount to be paid by the Company hereunder. In the event the Repurchase Option is deemed exercised by the Company pursuant to Section 3(a)(ii) hereof, the Company
may deem any transferee to have transferred the Shares or interest to Purchaser prior to their purchase by the Company, and payment of the purchase price by the Company to such transferee shall be deemed to satisfy Purchaser’s obligation to pay
such transferee for such Shares or interest, and also to satisfy the Company’s obligation to pay Purchaser for such Shares or interest. Any sale or transfer of the Shares shall be void unless the provisions of this Agreement are satisfied.

  
 -4-

 (f)        Termination of Rights. The
right of first refusal granted the Company by Section 3(b) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(c) above shall terminate upon the first sale of Common Stock
of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon
termination of the right of first refusal described in Section 3(b) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 6(a)(ii) herein and
delivered to Purchaser. 
 4.      Escrow of Unvested Shares. For purposes of
facilitating the enforcement of the provisions of Section 3 above, Purchaser agrees, immediately upon receipt of the certificate(s) for the Shares subject to the Repurchase Option, to deliver such certificate(s), together with an Assignment
Separate from Certificate in the form attached to this Agreement as Attachment A executed by Purchaser and by Purchaser’s spouse (if required for transfer), in blank, to the Secretary of the Company, or the Secretary’s
designee, to hold such certificate(s) and Assignment Separate from Certificate in escrow and to take all such actions and to effectuate all such transfers and/or releases as are in accordance with the terms of this Agreement. Purchaser hereby
acknowledges that the Secretary of the Company, or the Secretary’s designee, is so appointed as the escrow holder with the foregoing authorities as a material inducement to make this Agreement and that said appointment is coupled with an
interest and is accordingly irrevocable. Purchaser agrees that said escrow holder shall not be liable to any party hereof (or to any other party). The escrow holder may rely upon any letter, notice or other document executed by any signature
purported to be genuine and may resign at any time. Purchaser agrees that if the Secretary of the Company, or the Secretary’s designee, resigns as escrow holder for any or no reason, the Board of Directors of the Company shall have the power to
appoint a successor to serve as escrow holder pursuant to the terms of this Agreement. 

5.      Investment and Taxation Representations. In connection with the purchase of the
Shares, Purchaser represents to the Company the following: 
 (a)        Purchaser is
aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for
investment for his or her own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not
have any present intention to transfer the Shares to any person or entity. 

(b)        Purchaser understands that the Shares have not been registered under the Securities
Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 

(c)        Purchaser further acknowledges and understands that the securities must be held
indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands 

  
 -5-

 
that the Company is under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the
transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company. 
 (d)        Purchaser is familiar with the provisions of Rules 144 and 701, each promulgated under the Securities Act, which, in substance, permit limited
public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser
understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or Rule 701, which rules require, among other things, that the Company be subject to the reporting
requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified time periods, and under certain circumstances, that resales of
securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the restrictions set forth in paragraph (e) below. 

(e)        Purchaser further understands that in the event all of the applicable requirements of
Rule 144 or 701 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not
exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will have a
substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. 

(f)        Purchaser understands that Purchaser may suffer adverse tax consequences as a result
of Purchaser’s purchase or disposition of the Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the purchase or disposition of the Shares and that Purchaser is not relying
on the Company for any tax advice 
 6.      Restrictive Legends and
Stop-Transfer Orders. 
 (a)        Legends. The certificate or
certificates representing the Shares shall bear the following legends (as well as any legends required by applicable state and federal corporate and securities laws): 
  

	 	(i)	 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT
WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR 

  
 -6-

	 	 
DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT
OF 1933. 

  

	 	(ii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH
IS ON FILE WITH THE SECRETARY OF THE COMPANY. 

(b)        Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to
the same effect in its own records. 
 (c)        Refusal to Transfer.
The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right
to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 

7.      No Employment Rights. Nothing in this Agreement shall affect in any manner whatsoever
the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 

8.      Section 83(b) Election. Purchaser understands that Section 83(a) of the
Internal Revenue Code of 1986, as amended (the “Code”), taxes as ordinary income for a Nonstatutory Stock Option and as alternative minimum taxable income for an Incentive Stock Option the difference between the amount paid for the
Shares and the Fair Market Value of the Shares as of the date any restrictions on the Shares lapse. In this context, “restriction” means the right of the Company to buy back the Shares pursuant to the Repurchase Option set forth in
Section 3(a) of this Agreement. Purchaser understands that Purchaser may elect to be taxed at the time the Shares are purchased, rather than when and as the Repurchase Option expires, by filing an election under Section 83(b) (an
“83(b) Election”) of the Code with the Internal Revenue Service within 30 days from the date of purchase. Even if the Fair Market Value of the Shares at the time of the execution of this Agreement equals the amount paid for the
Shares, the election must be made to avoid income and alternative minimum tax treatment under Section 83(a) in the future. Purchaser understands that failure to file such an election in a timely manner may result in adverse tax consequences for
Purchaser. Purchaser further understands that an additional copy of such election form should be filed with his or her federal income tax return for the calendar year in which the date of this Agreement falls. Purchaser acknowledges that the
foregoing is only a summary of the effect of United States federal income taxation with respect to purchase of the 

  
 -7-

 
Shares hereunder, and does not purport to be complete. Purchaser further acknowledges that the Company has directed Purchaser to seek independent advice regarding the applicable provisions of the
Code, the income tax laws of any municipality, state or foreign country in which Purchaser may reside, and the tax consequences of Purchaser’s death. 
 Purchaser agrees that he or she will execute and deliver to the Company with this executed Agreement a copy of the Acknowledgment and Statement of Decision Regarding Section 83(b) Election (the
“Acknowledgment”) attached hereto as Attachment B. Purchaser further agrees that he or she will execute and submit with the Acknowledgment a copy of the 83(b) Election attached hereto as Attachment C (for tax
purposes in connection with the early exercise of an option) if Purchaser has indicated in the Acknowledgment his or her decision to make such an election. 
 9.      Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or the underwriters
managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however or whenever acquired
(other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days) from the effective date of such registration as may be
requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 

10.     Miscellaneous. 

(a)        Governing Law. This Agreement and all acts and transactions pursuant
hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law. 

(b)        Entire Agreement; Enforcement of Rights. This Agreement sets forth the
entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be
effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 

(c)        Severability. If one or more provisions of this Agreement are held to
be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall
be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 

(d)        Construction. This Agreement is the result of negotiations between and
has been reviewed by each of the parties hereto and their respective counsel, if any; accordingly, 

  
 -8-

 
this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 

(e)        Notices. Any notice required or permitted by this Agreement shall be in
writing and shall be deemed sufficient when delivered personally or sent by telegram or fax or 48 hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such
party’s address as set forth below or as subsequently modified by written notice. 

(f)        Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. 

(g)        Successors and Assigns. The rights and benefits of this Agreement shall
inure to the benefit of, and be enforceable by the Company’s successors and assigns. The rights and obligations of Purchaser under this Agreement may only be assigned with the prior written consent of the Company. 

(h)        California Corporate Securities Law. THE SALE OF THE SECURITIES WHICH
ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO THE
QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON THE QUALIFICATION
BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.]

 EXHIBIT B 
 NEOPHOTONICS CORPORATION 
 2004 STOCK OPTION PLAN 

[EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 

This Agreement (“Agreement”) is made as of
                , by and between NeoPhotonics Corporation, a Delaware corporation (the “Company”), and «Optionee_»
(“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the 2004 Stock Option Plan. 

1.      Exercise of Option.  Subject to the terms and conditions hereof, Purchaser
hereby elects to exercise his or her option to purchase              shares of the Common Stock (the “Shares”) of the Company under and pursuant to the
Company’s 2004 Stock Option Plan (the “Plan”) and the Stock Option Agreement granted                 , (the “Option
Agreement”).] The purchase price for the Shares shall be $             per Share for a total purchase price of
$                    . The term “Shares” refers to the purchased Shares and all securities received in replacement of the
Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities or other properties to which
Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2.      Time
and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution and delivery of this Agreement in accordance with the provisions of
Section 3(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be purchased by Purchaser (which shall be issued in Purchaser’s name) against payment of the exercise price
therefor by Purchaser by any method listed in Section 4 of the Option Agreement. 

3.      Limitations on Transfer.  In addition to any other limitation on transfer
created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the Shares except in compliance with the provisions below and applicable securities laws. 

(a)      Right of First Refusal.  Before any Shares held by Purchaser or any
transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this Section 3(a) (the “Right of First Refusal”). 
  (i)      Notice of Proposed Transfer.  The Holder of the Shares shall deliver to the Company a written notice (the “Notice”)
stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser 

 
or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each
proposed sale or transfer. The Holder shall offer the Shares at the same price (the “Offered Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 

   (ii)      Exercise of Right of First Refusal.  At any time
within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of
the Proposed Transferees, at the purchase price determined in accordance with subsection (iii) below. 

   (iii)     Purchase Price.  The purchase price (“Purchase
Price”) for the Shares purchased by the Company or its assignee(s) under this Section 3(a) shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration
shall be determined by the Board of Directors of the Company in good faith. 

   (iv)     Payment.  Payment of the Purchase Price shall be made, at
the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the times set
forth in the Notice. 
    (v)       Holder’s Right to
Transfer.  If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 3(a), then the Holder may sell or
otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 60 days after the date of the Notice and provided further that any such sale or
other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If
the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to
the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
    (vi)     Exception for Certain Family Transfers.  Anything to the contrary contained in this Section 3(a) notwithstanding, the
transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of Purchaser’s Immediate Family shall be exempt from the
provisions of this Section 3(a). “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold
the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 3. 

  
 -3-

  (b)      Involuntary
Transfer. 
   (i)      Company’s Right to Purchase upon Involuntary
Transfer.  In the event, at any time after the date of this Agreement, of any transfer by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in
Section 3(a)(vi) above) of all or a portion of the Shares by the record holder thereof, the Company shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement
or the fair market value of the Shares on the date of transfer. Upon such a transfer, the person acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the
Company for a period of thirty (30) days following receipt by the Company of written notice by the person acquiring the Shares. 
   (ii)      Price for Involuntary Transfer.  With respect to any stock to be transferred pursuant to Section 3(b)(i), the price per
Share shall be a price set by the Board of Directors of the Company that will reflect the current value of the stock in terms of present earnings and future prospects of the Company. The Company shall notify Purchaser or his or her executor of the
price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the valuation as determined by the Board of Directors of the
Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne equally by the Company and the Purchaser. 

 (c)      Assignment.  The right of the Company to purchase any part of the
Shares may be assigned in whole or in part to any shareholder or shareholders of the Company or other persons or organizations. 
  (e)      Restrictions Binding on Transferees.  All transferees of Shares or any interest therein will receive and hold such Shares or interest
subject to the provisions of this Agreement. Any sale or transfer of the Company’s Shares shall be void unless the provisions of this Agreement are satisfied. 
  (f)      Termination of Rights.  The right of first refusal granted the Company by Section 3(a) above and the option to repurchase the
Shares in the event of an involuntary transfer granted the Company by Section 3(b) above shall terminate upon the first sale of Common Stock of the Company to the general public pursuant to a registration statement filed with and declared
effective by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the right of first refusal described in Section 3(b) above, a new certificate or
certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 5(a)(ii) herein and delivered to Purchaser. 
 4.      Investment and Taxation Representations.  In connection with the purchase of the Shares, Purchaser represents to the Company the following:

  
 -4-

  (a)      Purchaser is aware of the Company’s
business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own
account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to
transfer the Shares to any person or entity. 
  (b)      Purchaser understands that the
Shares have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 

 (c)      Purchaser further acknowledges and understands that the securities must be held
indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the Company is under no obligation to register the securities.
Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the
Company. 
  (d)      Purchaser is familiar with the provisions of Rules 144 and 701,
each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a
non-public offering subject to the satisfaction of certain conditions. Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or Rule 701, which
rules require, among other things, that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for
certain specified time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the
restrictions set forth in paragraph (e) below. 
  (e)      Purchaser further
understands that in the event all of the applicable requirements of Rule 144 or 701 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that,
notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and
otherwise than pursuant to Rule 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk. 
  (f)      Purchaser understands that Purchaser
may suffer adverse tax consequences as a result of Purchaser’s purchase or disposition of the Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in

  
 -5-

 
connection with the purchase or disposition of the Shares and that Purchaser is not relying on the Company for any tax advice. 

5.        Restrictive Legends and Stop-Transfer Orders. 

 (a)        Legends. The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable state and federal corporate and securities laws): 
  

	 	(i)	THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR
IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE
SECURITIES ACT OF 1933. 

  

	 	(ii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH
IS ON FILE WITH THE SECRETARY OF THE COMPANY. 

 (b)        Stop-Transfer Notices.  Purchaser agrees that, in order
to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records. 
  (c)        Refusal to
Transfer.  The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such
Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 
 6.        No Employment Rights.  Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a
parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 
 7.        Lock-Up Agreement.  In connection with the initial public offering of the Company’s securities and upon request of the
Company or the underwriters managing any 

  
 -6-

 
underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of
the Company however or whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days) from the effective
date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 

8.        Miscellaneous. 

 (a)      Governing Law. This Agreement and all acts and transactions pursuant hereto
and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law. 

 (b)      Entire Agreement; Enforcement of Rights. This Agreement sets forth the entire
agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective
unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 

 (c)      Severability. If one or more provisions of this Agreement are held to be
unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be
excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 

 (d)      Construction. This Agreement is the result of negotiations between and has
been reviewed by each of the parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the
parties hereto. 
  (e)      Notices. Any notice required or permitted by this
Agreement shall be in writing and shall be deemed sufficient when delivered personally or sent by telegram or fax or forty-eight (48) hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and
addressed to the party to be notified at such party’s address as set forth below or as subsequently modified by written notice. 
  (f)      Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together
shall constitute one instrument. 
  (g)      Successors and Assigns. The
rights and benefits of this Agreement shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. 

  
 -7-

 The rights and obligations of Purchaser under this Agreement may only be assigned with the prior written
consent of the Company. 
  (h)      California Corporate Securities
Law.  THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY
PART OF THE CONSIDERATION THEREFOR PRIOR TO THE QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT
ARE EXPRESSLY CONDITIONED UPON THE QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

 NEOPHOTONICS CORPORATION 

2004 STOCK OPTION PLAN 
 STOCK OPTION AGREEMENT 

1.        Grant of Option. 

(i)      NeoPhotonics Corporation, a company incorporated in the state of Delaware in the United States of
America (the “Company”), hereby grants to «Optionee_» (“Optionee”), an
option (the “Option”) to purchase the total number of shares of Common Stock (the “Shares”) set forth in the Notice of Stock Option Grant (the “Notice”), at the exercise price per Share set forth in
the Notice (the “Exercise Price”) subject to the terms, definitions and provisions of the NeoPhotonics Corporation 2004 Stock Option Plan (the “Plan”) adopted by the Company, which is incorporated in this Agreement
by reference. 
 (ii)      Unless otherwise defined in this Agreement, the terms used in this
Agreement shall have the meanings defined in the Plan. Optionee is required as a condition to receipt of this Option to provide to the Company an executed copy of Exhibit A attached hereto (“Investor Certificate”).

 2.        Exercise of Option. This Option shall be exercisable during
its term in accordance with the Vesting/Exercise Schedule set out in the Notice and with the provisions of Section 10 of the Plan as follows: 
 (a)      Right to Exercise. 

(i)      This Option may not be exercised for a fraction of a share. 

(ii)      In the event of Optionee’s death, disability or other termination of employment, the
exercisability of the Option is governed by Section 4 below, subject to the limitations contained in this Section 2. 

(iii)      In no event may this Option be exercised after the Expiration Date of the Option as set forth
in the Notice. 
 (b)      Method of Exercise. 

(i)      This Option shall be exercisable by execution and delivery of the Exercise Notice and Restricted
Stock Purchase Agreement attached hereto as Exhibit B, or any other 

 
form of written notice approved for such purpose by the Company which shall state Optionee’s election to exercise the Option, the number of Shares in respect of which the Option is being
exercised, and such other representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by Optionee
and shall be delivered to the Company by such means as are determined by the Plan Administrator in its discretion to constitute adequate delivery. The written notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed
to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price. 

(ii)      As a condition to the exercise of this Option and as further set forth in Section 12 of the
Plan, Optionee agrees to make adequate provision for PRC or US federal, state or other tax withholding obligations, if any, which arise upon the vesting or exercise of the Option, or disposition of Shares, whether by withholding or as otherwise
permitted by Applicable Laws. 
 (iii)      The Company is not obligated, and will have no
liability for failure, to issue or deliver any Shares upon exercise of the Option unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. This
Option may not be exercised if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable PRC or U.S. federal or state securities or other law or
regulation. As a condition to the exercise of this Option, the Company may, on the advice of counsel, require Optionee to make representations and warranties to the Company as may be required by the Applicable Laws. Assuming compliance with
Applicable Laws, for income tax purposes the Shares shall be considered transferred to Optionee on the date on which the Option is exercised with respect to such Shares. 
 3.        Method of Payment.  Payment of the Exercise Price shall be by any of the following, or a combination of the following, at the
election of Optionee and, where applicable, shall be payable in U.S. Dollars with Optionee’s own legally acquired foreign currency: 
 (a)      cash, check or wire transfer; 

(b)      cancellation of indebtedness; 

(c)      prior to the date, if any, upon which the Common Stock becomes a Listed Security, by surrender of
other shares of Common Stock of the Company that have an aggregate Fair Market Value on the date of surrender equal to the Exercise Price of the Shares as to which the Option is being exercised. In the case of shares acquired directly or indirectly
from the Company, such shares must have been owned by Optionee for more than six (6) months on the date of surrender (or such other period of time as is necessary to avoid the Company’s incurring adverse accounting charges); or 

(d)      following the date, if any, upon which the Common Stock is a Listed Security, and if the Company
is at such time permitting “same day sale” cashless brokered exercises, delivery of a properly executed exercise notice together with irrevocable instructions to a broker participating in such cashless brokered exercise program to deliver
promptly to the Company the amount required to pay the exercise price (and applicable withholding taxes). 

4.        Termination of Relationship.  Following the date of termination
of Optionee’s Continuous Service Status for any reason (the “Termination Date”), Optionee may exercise the Option only as set forth in the Notice and this Section 4. To the extent that Optionee is not entitled to exercise
this Option as of the Termination Date, or if Optionee does not exercise this Option within the 

  
 -2-

 
Termination Period set forth in the Notice or the termination periods set forth below, the Option shall terminate in its entirety. In no event, may any Option be exercised after the Expiration
Date of the Option as set forth in the Notice. 

(a)      Termination.  In the event of termination of Optionee’s Continuous
Service Status other than as a result of Optionee’s disability or death or for Cause (as defined in the Plan), Optionee may, to the extent Optionee is vested in the Option Shares at the date of such termination (the “Termination
Date”), exercise this Option during the Termination Period set forth in the Notice. 

(b)      Other Terminations.  In connection with any termination other than a
termination covered by Section 4(a), Optionee may exercise the Option only as described below: 

(i)      Termination upon Disability of Optionee.  In the event of termination of
Optionee’s Continuous Service Status as a result of Optionee’s disability, Optionee may, but only within six months from the Termination Date, exercise this Option to the extent Optionee was vested in the Option Shares as of such

 Exhibit B 

NEOPHOTONICS CORPORATION 
 2004 STOCK OPTION PLAN 
 EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE
AGREEMENT 
 This Agreement (“Agreement”) is made as of
                , by and between NeoPhotonics Corporation, a corporation incorporated in the state of Delaware in the United States of America (the
“Company”), and «Optionee_» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the 2004 Stock Option Plan.

 1.        Exercise of Option. 

Subject to the terms and conditions hereof, Purchaser hereby elects to exercise his or her vested option to purchase «NoofShares_» shares of the Common Stock (the “Shares”) of the Company under and pursuant to the
Company’s 2004 Stock Option Plan (the “Plan”) and the Stock Option Agreement granted «GrantDate_» (the “Option Agreement”). The purchase price for the Shares shall be
$«NoofSharesExercisePrice_» per Share for a total purchase price of
$                        . The term “Shares” refers to the purchased Shares and all securities received
in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities or other
properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. As a condition to exercise of the Option, Purchaser shall provide an executed copy of the investor certificate attached hereto as Exhibit A (the
“Investor Certificate”) to the Company. 
 2.        Time and
Place of Exercise.  The offer, purchase and sale of the Shares under this Agreement shall occur at the principal office in the PRC of the Company’s subsidiary NeoPhotonics (China) Co., Ltd. simultaneously with the execution
and delivery of this Agreement in accordance with the provisions of Section 2(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be purchased by Purchaser (which shall be
issued in Purchaser’s name) against payment of the exercise price therefore by Purchaser by any method listed in Section 3 of the Option Agreement. 
 3.        Limitations on Transfer.  In addition to any other limitation on transfer created by applicable securities laws (including any
limitations arising under the Investor Certificate), Purchaser shall not assign, encumber or dispose of any interest in the Shares while the Shares are subject to the Company’s Repurchase Option (as defined below). After any Shares have been
released from such Repurchase Option, Purchaser shall not assign, encumber or dispose of any interest in such Shares except in compliance with the provisions below and applicable securities laws. 

(a)      Right of First Refusal.  Before any Shares held by Purchaser or any
transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this Section 3(b) (the “Right of First Refusal”). 
 (i)      Notice of Proposed Transfer.  The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating:
(i) the Holder’s bona fide intention to sell or 

 
otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to
each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder shall offer the Shares at the same price (the “Offered Price”) and upon the same terms (or terms as similar as reasonably
possible) to the Company or its assignee(s). 
 (ii)      Exercise of Right of First
Refusal.  At any time within twenty (20) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to
be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (iii) below. 
 (iii)      Purchase Price.  The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under
this Section 3(b) shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith, with
the consent of the Purchaser. 
 (iv)      Payment.  Payment of the
Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within twenty (20) days after receipt of the
Notice or in the manner and at the times set forth in the Notice. 
 (v)      Holder’s
Right to Transfer.  If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 3(b), then the Holder may
sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 60 days after the date of the Notice and provided further that any such
sale or other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed
Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice
shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

(vi)      Exception for Certain Family Transfers.  Anything to the contrary
contained in this Section 3(b) notwithstanding, the transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of
Purchaser’s Immediate Family shall be exempt from the provisions of this Section 3(b). “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case,
the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 3.

 (c)      Involuntary Transfer. 

(i)      Company’s Right to Purchase upon Involuntary Transfer.  In the
event, at any time after the date of this Agreement, of any transfer by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth

  
 -2-

 
in Section 3(b)(vi) above) of all or a portion of the Shares by the record holder thereof, the Company shall have an option to purchase all of the Shares transferred at the greater of the
purchase price paid by Purchaser pursuant to this Agreement or the Fair Market Value of the Shares on the date of transfer. Upon such a transfer, the person acquiring the Shares shall promptly notify the Secretary of the Company of such transfer.
The right to purchase such Shares shall be provided to the Company for a period of twenty (20) days following receipt by the Company of written notice by the person acquiring the Shares. 

(ii)      Price for Involuntary Transfer.  With respect to any stock to be
transferred pursuant to Section 3(c)(i), the price per Share shall be a price set by the Board of Directors of the Company that will reflect the current value of the stock in terms of present earnings and future prospects of the Company. The
Company shall notify Purchaser or his or her executor of the price so determined within twenty (20) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the
valuation as determined by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne
equally by the Company and the Purchaser. 
 (d)      Assignment.  The
right of the Company to purchase any part of the Shares may be assigned in whole or in part to any shareholder or shareholders of the Company or other persons or organizations. 

(e)      Restrictions Binding on Transferees.  All transferees of Shares or any
interest therein will receive and hold such Shares or interest subject to the provisions of this Agreement, including, insofar as applicable, the Repurchase Option. In the event of any purchase by the Company hereunder where the Shares or interest
are held by a transferee, the transferee shall be obligated, if requested by the Company, to transfer the Shares or interest to the Purchaser for consideration equal to the amount to be paid by the Company hereunder. In the event the Repurchase
Option is deemed exercised by the Company pursuant to Section 3(a)(ii) hereof, the Company may deem any transferee to have transferred the Shares or interest to Purchaser prior to their purchase by the Company, and payment of the purchase price
by the Company to such transferee shall be deemed to satisfy Purchaser’s obligation to pay such transferee for such Shares or interest, and also to satisfy the Company’s obligation to pay Purchaser for such Shares or interest. Any sale or
transfer of the Shares shall be void unless the provisions of this Agreement are satisfied. 

(f)      Termination of Rights.  The right of first refusal granted the Company by
Section 3(b) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(c) above shall terminate upon the first sale of Common Stock of the Company to the general public pursuant
to a registration statement filed with and declared effective by the Securities and Exchange Commission under the United States Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the right of first
refusal described in Section 3(b) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 6(a)(ii) herein and delivered to Purchaser.

 4.        Investment and Taxation Representations.  In
connection with the purchase of the Shares, Purchaser represents to the Company the following: 

(a)      Purchaser is aware of the Company’s business affairs and financial condition and has acquired
sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for resale in
connection with, any “distribution” thereof within the 

  
 -3-

 
meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity. 

(b)      Purchaser understands that the Shares have not been registered under the Securities Act by reason
of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
 (c)      Purchaser further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an
exemption from such registration is available. Purchaser further acknowledges and understands that the Company is under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be
imprinted with a legend which prohibits the transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company. 

(d)      Purchaser is familiar with the provisions of Regulation S and Rules 144 and 701, each
promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public
offering subject to the satisfaction of certain conditions. Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or Rule 701, which rules require,
among other things, that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified
time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the restrictions set forth
in paragraph (e) below. 
 (e)      Purchaser further understands that in the event all of
the applicable requirements of Regulation S or Rules 144 or 701 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the
fact that Regulation S and Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and
otherwise than pursuant to Regulation S or Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers
who participate in such transactions do so at their own risk. 
 (f)      Purchaser understands
that Purchaser may suffer adverse tax consequences as a result of Purchaser’s purchase or disposition of the Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the purchase
or disposition of the Shares and that Purchaser is not relying on the Company for any tax advice. 

(g)      Purchaser represents and warrants to the Company that (i) Purchaser is not a U.S. Person (as
defined in Regulation S under the U.S. Securities Act of 1933, as amended) and (ii) Purchaser has complied with and received any required approval under Applicable Laws before exercising the Option. 

(h)      Purchaser has read, understands and has executed the Investor Certificate. 

  
 -4-

 5.        Restrictive Legends and
Stop-Transfer Orders. 
 (a)      Legends.  The certificate or
certificates representing the Shares shall bear the following legends (as well as any legends required by applicable state and federal corporate and securities laws): 
 (i)      THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) AND HAVE BEEN
ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED UNLESS DONE IN COMPLIANCE WITH REGULATION S OF THE SECURITIES ACT, EFFECTED PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO, OR UNDER ANOTHER EXEMPTION AVAILABLE UNDER THE SECURITIES ACT (AS TO WHICH AVAILABILITY THE COMPANY MAY REQUIRE THE SELLER/TRANSFEROR TO PROVIDE AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY).

 (ii)      THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE
WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 
 (b)      Stop-Transfer Notices.  Purchaser agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue
appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

(c)      Refusal to Transfer.  The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or
other transferee to whom such Shares shall have been so transferred. 

6.        No Employment Rights.  Nothing in this Agreement shall affect
in any manner whatsoever the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 

7.        Lock-Up Agreement.  In connection with the initial public
offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any securities of the Company however or whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such
period of time (up to, but not exceeding, 180 days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the
underwriters at the time of the public offering.

entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be
effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 

(c)      Severability.  If one or more provisions of this Agreement are held to be
unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be
excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

ADOPTED BY THE BOARD OF DIRECTORS:

 TERMINATION DATE: APRIL 13, 2020

  

	1.	 GENERAL. 

 (a)    Eligible Award Recipients.    The persons eligible to receive Awards are Employees, Directors and Consultants. 

(b)    Available Awards.    The Plan provides for the grant of the
following Awards: (i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards, (vi) Performance Stock Awards,
(vii) Performance Cash Awards, and (viii) Other Stock Awards. 

(c)    Purpose.    The Company, by means of the Plan, seeks to secure and
retain the services of the group of persons eligible to receive Awards as set forth in Section 1(a), to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and to provide a means by
which such eligible recipients may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Awards. 
  

	2.	 ADMINISTRATION. 

 (a)    Administration by Board.    The Board shall administer the Plan unless and until the Board delegates administration of the Plan to a Committee or
Committees, as provided in Section 2(c). 
 (b)    Powers of
Board.    The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan: 
 (i)      To determine from time to time (A) which of the persons eligible under the Plan shall be granted Awards; (B) when and how each Award shall be
granted; (C) what type or combination of types of Award shall be granted; (D) the provisions of each Award granted (which need not be identical), including the time or times when a person shall be permitted to receive cash or Common Stock
pursuant to a Stock Award; (E) the number of shares of Common Stock with respect to which a Stock Award shall be granted to each such person; and (F) the Fair Market Value applicable to a Stock Award. 

(ii)      To construe and interpret the Plan and Awards granted under it, and to
establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement or in the written terms of a
Performance Cash Award, in a manner and to the extent it shall deem necessary or expedient to make the Plan or Award fully effective. 

 (iii)      To settle all controversies
regarding the Plan and Awards granted under it. 
 (iv)      To accelerate
the time at which an Award may first be exercised or the time during which an Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Award stating the time at which it may first be exercised or the
time during which it will vest. 
 (v)      To suspend or terminate the
Plan at any time. Suspension or termination of the Plan shall not impair rights and obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant. 

(vi)      To amend the Plan in any respect the Board deems necessary or advisable,
including, without limitation, by adopting amendments relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to bring the Plan or Awards granted under the Plan into compliance
therewith, subject to the limitations, if any, of applicable law. However, except as provided in Section 9(a) relating to Capitalization Adjustments, to the extent required by applicable law or listing requirements, stockholder approval shall
be required for any amendment of the Plan that either (A) materially increases the number of shares of Common Stock available for issuance under the Plan, (B) materially expands the class of individuals eligible to receive Awards under the
Plan, (C) materially increases the benefits accruing to Participants under the Plan or materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (D) materially extends the term of the Plan, or
(E) expands the types of Awards available for issuance under the Plan. Except as provided above, rights under any Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (1) the Company requests
the consent of the affected Participant, and (2) such Participant consents in writing. 

(vii)      To submit any amendment to the Plan for stockholder approval, including,
but not limited to, amendments to the Plan intended to satisfy the requirements of (A) Section 162(m) of the Code regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to
Covered Employees, (B) Section 422 of the Code regarding “incentive stock options” or (C) Rule 16b-3. 
 (viii)      To approve forms of Award Agreements for use under the Plan and to amend the terms of any one or more Awards, including, but not limited to, amendments to
provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided however, that except with respect to amendments
that disqualify or impair the status of an Incentive Stock Option, a Participant’s rights under any Award shall not be impaired by any such amendment unless (A) the Company requests the consent of the affected Participant, and
(B) such Participant consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, the Board may amend the terms of any one or more Awards without the affected Participant’s consent if necessary
to maintain the qualified status of the Award as an Incentive Stock Option or to bring the Award into compliance with Section 409A of the Code. 

 (ix)      Generally, to exercise such
powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and that are not in conflict with the provisions of the Plan or Awards. 

(x)      To adopt such procedures and sub-plans as are necessary or appropriate to
permit participation in the Plan by Employees, Directors or Consultants who are foreign nationals or employed outside the United States. 
 (xi)      To effect, at any time and from time to time, with the consent of any adversely affected Participant, (A) the reduction of the exercise price (or strike
price) of any outstanding Option or SAR under the Plan; (B) the cancellation of any outstanding Option or SAR under the Plan and the grant in substitution therefor of (1) a new Option or SAR under the Plan or another equity plan of the
Company covering the same or a different number of shares of Common Stock, (2) a Restricted Stock Award, (3) a Restricted Stock Unit Award, (4) an Other Stock Award, (5) cash and/or (6) other valuable consideration (as
determined by the Board, in its sole discretion); or (C) any other action that is treated as a repricing under generally accepted accounting principles. 
 (c)    Delegation to Committee. 

(i)      General.    The Board may delegate some or all of the
administration of the Plan to a Committee or Committees. If administration of the Plan is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have
been delegated to the Committee, including the power to delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the
Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may retain the authority to concurrently administer the Plan with the
Committee and may, at any time, revest in the Board some or all of the powers previously delegated. 

(ii)      Section 162(m) and Rule 16b-3 Compliance.    The
Committee may consist solely of two or more Outside Directors, in accordance with Section 162(m) of the Code, or solely of two or more Non-Employee Directors, in accordance with Rule 16b-3. 

(d)    Delegation to an Officer.    The Board may delegate to one
(1) or more Officers the authority to do one or both of the following (i) designate Employees who are providing Continuous Service to the Company or any of its Subsidiaries who are not Officers to be recipients of Options and Stock
Appreciation Rights (and, to the extent permitted by applicable law, other Stock Awards) and the terms thereof, and (ii) determine the number of shares of Common Stock to be subject to such Stock Awards granted to such Employees; provided,
however, that the Board resolutions regarding such delegation shall specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award to himself
or herself. Notwithstanding the foregoing, the Board may not delegate authority to an Officer to determine the Fair Market Value pursuant to Section 13(w)(iii) below. 

 (e)    Effect of Board’s
Decision.    All determinations, interpretations and constructions made by the Board in good faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons. 

 

	3.	 SHARES SUBJECT TO THE PLAN. 

(a)    Share Reserve.    Subject to Section 9(a) relating to
Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards from and after the Effective Date shall not exceed 865,420 shares (the “Share Reserve”). In addition, the
number of shares of Common Stock available for issuance under the Plan shall automatically increase on January 1st of each year for a period of ten (10) years commencing on January 1, 2011 and ending on (and including) January 1,
2020, in an amount equal to three and one-half percent (3.5%) of the total number of shares of Common Stock outstanding on December 31st of the preceding calendar year. Notwithstanding the foregoing, the Board may act prior to the first
day of any calendar year, to provide that there shall be no increase in the share reserve for such calendar year or that the increase in the share reserve for such calendar year shall be a lesser number of shares of Common Stock than would otherwise
occur pursuant to the preceding sentence. For clarity, the limitation in this Section 3(a) is a limitation in the number of shares of Common Stock that may be issued pursuant to the Plan. Accordingly, this Section 3(a) does not limit the
granting of Stock Awards except as provided in Section 7(a). Shares may be issued in connection with a merger or acquisition as permitted by NASDAQ Listing Rule 5635(c) or, if applicable, NYSE Listed Company Manual Section 303A.08, AMEX
Company Guide Section 711 or other applicable rule, and such issuance shall not reduce the number of shares available for issuance under the Plan. Furthermore, if a Stock Award or any portion thereof (i) expires or otherwise terminates
without all of the shares covered by such Stock Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, termination or settlement shall not reduce (or otherwise
offset) the number of shares Common Stock that may be available for issuance under the Plan. 

(b)    Reversion of Shares to the Share Reserve.    If any shares of
common stock issued pursuant to a Stock Award are forfeited back to or repurchased by the Company because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited or
repurchased shall revert to and again become available for issuance under the Plan. Any shares reacquired by the Company pursuant to Section 8(g) or as consideration for the exercise of an Option shall again become available for issuance under
the Plan. 
 (c)    Incentive Stock Option
Limit.    Notwithstanding anything to the contrary in this Section 3 and, subject to the provisions of Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that
may be issued pursuant to the exercise of Incentive Stock Options shall be 8,000,000 shares of Common Stock. 

(d)    Section 162(m) Limitation on Annual Grants.    Subject to the
provisions of Section 9(a) relating to Capitalization Adjustments, at such time as the Company may be subject to the applicable provisions of Section 162(m) of the Code, a maximum of eight hundred thousand (800,000) shares of Common
Stock subject to Options, Stock Appreciation Rights and Other Stock Awards whose value is determined by reference to an increase over an exercise or 

 
strike price of at least one hundred percent (100%) of the Fair Market Value on the date the Stock Award is granted may be granted to any Participant during any calendar year.
Notwithstanding the foregoing, if any additional Options, Stock Appreciation Rights or Other Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at least one hundred (100% percent) of the Fair
Market Value on the date the Stock Award are granted to any Participant during any calendar year, compensation attributable to the exercise of such additional Stock Awards shall not satisfy the requirements to be considered “qualified
performance-based compensation” under Section 162(m) of the Code unless such additional Stock Awards are approved by the Company’s stockholders. 
 (e)    Source of Shares.    The stock issuable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares
repurchased by the Company on the open market or otherwise. 
  

	4.	 ELIGIBILITY. 

 (a)    Eligibility for Specific Stock Awards.    Incentive Stock Options may be granted only to employees of the Company or a “parent corporation”
or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and (f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants; provided, however,
Nonstatutory Stock Options and SARs may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company, as such term is defined in Rule 405, unless the stock underlying
such Stock Awards is treated as “service recipient stock” under Section 409A of the Code because the Stock Awards are granted pursuant to a corporate transaction (such as a spin off transaction) or unless such Stock Awards comply with
the distribution requirements of Section 409A of the Code. 
 (b)    Ten Percent
Stockholders.    A Ten Percent Stockholder shall not be granted an Incentive Stock Option unless the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant
and the Option is not exercisable after the expiration of five (5) years from the date of grant. 
  

	5.	 PROVISIONS RELATING TO OPTIONS AND STOCK
APPRECIATION RIGHTS. 

 Each Option or SAR shall be in such
form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate
certificate or certificates shall be issued for shares of Common Stock purchased on exercise of each type of Option. If an Option is not specifically designated as an Incentive Stock Option, then the Option shall be a Nonstatutory Stock Option. The
provisions of separate Options or SARs need not be identical; provided, however, that each Option Agreement or Stock Appreciation Right Agreement shall conform to (through incorporation of provisions hereof by reference in the applicable
Award Agreement or otherwise) the substance of each of the following provisions: 

 (a)    Term.    Subject to
the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or SAR shall be exercisable after the expiration of ten (10) years from the date of its grant or such shorter period specified in the Award Agreement. 

(b)    Exercise Price.    Subject to the provisions of Section 4(b)
regarding Ten Percent Stockholders, the exercise price (or strike price) of each Option or SAR shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Option or
SAR is granted. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise price (or strike price) lower than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR if such
Option or SAR is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Sections 409A and, if applicable, 424(a) of
the Code. Each SAR will be denominated in shares of Common Stock equivalents. 

(c)    Purchase Price for Options.    The purchase price of Common Stock
acquired pursuant to the exercise of an Option shall be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board shall have the
authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment.
The permitted methods of payment are as follows: 
 (i)      by cash,
check, bank draft or money order payable to the Company; 

(ii)      pursuant to a program developed under Regulation T as promulgated by the
Federal Reserve Board that, prior to the issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from
the sales proceeds; 
 (iii)      by delivery to the Company (either by
actual delivery or attestation) of shares of Common Stock; 
 (iv)      if
the option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value
that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such
reduction in the number of whole shares to be issued; provided, further, that shares of Common Stock will no longer be subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are
reduced to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 

(v)      in any other form of legal consideration that may be acceptable to the
Board and specified in the applicable award agreement. 

 (d)    Exercise and Payment of a
SAR.    To exercise any outstanding Stock Appreciation Right, the Participant must provide written notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such
Stock Appreciation Right. The appreciation distribution payable on the exercise of a Stock Appreciation Right will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the
Stock Appreciation Right) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to which the Participant is exercising the Stock
Appreciation Right on such date, over (B) the strike price that will be determined by the Board at the time of grant of the Stock Appreciation Right. The appreciation distribution in respect to a Stock Appreciation Right may be paid in Common
Stock, in cash, in any combination of the two or in any other form of consideration, as determined by the Board and contained in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 

(e)    Transferability of Options and SARs.    The Board may, in its sole
discretion, impose such limitations on the transferability of Options and SARs as the Board shall determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs
shall apply: 
 (i)      Restrictions on
Transfer.    An Option or SAR shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Participant only by the Participant; provided,
however, that the Board may, in its sole discretion, permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax and securities laws upon the Participant’s request. Except as explicitly provided herein, neither
an Option nor a SAR may be transferred for consideration. 

(ii)      Domestic Relations Orders.    Notwithstanding the
foregoing, an Option or SAR may be transferred pursuant to a domestic relations order; provided, however, that if an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such
transfer. 
 (iii)      Beneficiary
Designation.    Notwithstanding the foregoing, the Participant may, by delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company and any broker designated by the Company to
effect Option exercises, designate a third party who, in the event of the death of the Participant, shall thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the
absence of such a designation, the executor or administrator of the Participant’s estate shall be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. 

(f)    Vesting Generally.    The total number of shares of Common Stock
subject to an Option or SAR may vest and therefore become exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be exercised
(which may be based on the satisfaction of Performance Goals or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to any

 
Option or SAR provisions governing the minimum number of shares of Common Stock as to which an Option or SAR may be exercised. 

(g)    Termination of Continuous Service.    Except as otherwise provided
in the applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates (other than for Cause or upon the Participant’s death or Disability), the Participant may
exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of termination of Continuous Service) but only within such period of time ending on the earlier of (i) the date three
(3) months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the applicable Award Agreement), or (ii) the expiration of the term of the Option or SAR as set forth in the
Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the time specified herein or in the Award Agreement (as applicable), the Option or SAR shall terminate. 

(h)    Extension of Termination Date.    If the exercise of an Option or
SAR following the termination of the Participant’s Continuous Service (other than for Cause or upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate
the registration requirements under the Securities Act, then the Option or SAR shall terminate on the earlier of (i) the expiration of a total period of three (3) months (that need not be consecutive) after the termination of the
Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award
Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock received upon exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than
for Cause) would violate the Company’s insider trading policy, then the Option or SAR shall terminate on the earlier of (i) the expiration of a period equal to the applicable post-termination exercise period after the termination of the
Participant’s Continuous Service during which the sale of the Common Stock received upon exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the expiration of the term of the Option
or SAR as set forth in the applicable Award Agreement. 
 (i)    Disability of
Participant.    Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates as a result of the
Participant’s Disability, the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of
time ending on the earlier of (i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period specified in the Award Agreement), or (ii) the expiration of the term of the Option or
SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the time specified herein or in the Award Agreement (as applicable), the Option or SAR (as
applicable) shall terminate. 
 (j)    Death of
Participant.    Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if (i) a Participant’s

 
Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the period (if any) specified in the Award Agreement after the termination of
the Participant’s Continuous Service for a reason other than death, then the Option or SAR may be exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant’s estate, by
a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the Participant’s death, but only within the period ending on the earlier of (i) the date
eighteen (18) months following the date of death (or such longer or shorter period specified in the Award Agreement), or (ii) the expiration of the term of such Option or SAR as set forth in the Award Agreement. If, after the
Participant’s death, the Option or SAR is not exercised within the time specified herein or in the Award Agreement (as applicable), the Option or SAR shall terminate. 

(k)    Termination for Cause.    Except as explicitly provided otherwise
in a Participant’s Award Agreement, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR shall terminate upon the date on which the event giving rise to the termination occurred, and the Participant shall be
prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous Service. 
 (l)    Non-Exempt Employees.    No Option or SAR granted to an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as
amended, shall be first exercisable for any shares of Common Stock until at least six (6) months following the date of grant of the Option or SAR. Notwithstanding the foregoing, consistent with the provisions of the Worker Economic Opportunity
Act, (i) in the event of the Participant’s death or Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or (iv) upon the
Participant’s retirement (as such term may be defined in the Participant’s Award Agreement or in another applicable agreement or in accordance with the Company’s then current employment policies and guidelines), any such vested
Options and SARs may be exercised earlier than six months following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR
will be exempt from his or her regular rate of pay. 
  

	6.	 PROVISIONS OF STOCK AWARDS OTHER THAN
OPTIONS AND SARS. 

(a)    Restricted Stock Awards.    Each Restricted Stock Award Agreement
shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Common Stock may be (x) held in book entry
form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, which certificate shall be held in such form and manner as determined by the Board. The
terms and conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical; provided, however, that each Restricted Stock Award
Agreement shall conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 

(i)      Consideration.    A Restricted Stock Award may be
awarded in consideration for (A) cash, check, bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) that may be
acceptable to the Board, in its sole discretion, and permissible under applicable law. 

(ii)      Vesting.    Shares of Common Stock awarded under the
Restricted Stock Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 
 (iii)      Termination of Participant’s Continuous Service.    If a Participant’s Continuous Service terminates, the Company may receive
through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award Agreement.

 (iv)      Transferability.    Rights to acquire
shares of Common Stock under the Restricted Stock Award Agreement shall be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board shall determine in its sole
discretion, so long as Common Stock awarded under the Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock Award Agreement. 
 (v)      Dividends.    A Restricted Stock Award Agreement may provide that any dividends paid on Restricted Stock will be subject to the same
vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 
 (b)    Restricted Stock Unit Awards.    Each Restricted Stock Unit Award Agreement shall be in such form and shall contain such terms and conditions as the
Board shall deem appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit Award Agreements need not be identical; provided,
however, that each Restricted Stock Unit Award Agreement shall conform to (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions: 

(i)      Consideration.    At the time of grant of a Restricted
Stock Unit Award, the Board will determine the consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for
each share of Common Stock subject to a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law. 

(ii)      Vesting.    At the time of the grant of a Restricted
Stock Unit Award, the Board may impose such restrictions on or conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 

(iii)      Payment.    A Restricted Stock Unit Award may be
settled by the delivery of shares of Common Stock, their cash equivalent, any combination thereof or in any other form 

 
of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. 
 (iv)      Additional Restrictions.    At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems appropriate, may impose
such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award. 

(v)      Dividend Equivalents.    Dividend equivalents may be
credited in respect of shares of Common Stock covered by a Restricted Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be
converted into additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents
will be subject to all of the same terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate. 
 (vi)      Termination of Participant’s Continuous Service.    Except as otherwise provided in the applicable Restricted Stock Unit Award
Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service. 
 (c)    Performance Awards. 

(i)      Performance Stock Awards.    A Performance Stock Award
is a Stock Award that may vest or may be exercised contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Stock Award may, but need not, require the completion of a specified period of Continuous
Service. The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained shall be conclusively determined by the
Committee, in its sole discretion. The maximum number of shares covered by an Award that may be granted to any Participant in a calendar year attributable to Stock Awards described in this Section 6(c)(i) (whether the grant, vesting or exercise
is contingent upon the attainment during a Performance Period of the Performance Goals) shall not exceed four hundred thousand (400,000) shares of Common Stock. The Board may provide for or, subject to such terms and conditions as the Board may
specify, may permit a Participant to elect for, the payment of any Performance Stock Award to be deferred to a specified date or event. In addition, to the extent permitted by applicable law and the applicable Award Agreement, the Board may
determine that cash may be used in payment of Performance Stock Awards. 

(ii)      Performance Cash Awards.    A Performance Cash Award
is a cash award that may be paid contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Cash Award may also require the completion of a specified period of Continuous Service. At the time of grant of a
Performance Cash Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained shall be conclusively
determined by the Committee, in its sole discretion. In any calendar year, the 

 
Committee may not grant a Performance Cash Award that has a maximum value that may be paid to any Participant in excess of ten million dollars ($10,000,000). The Board may provide for or, subject
to such terms and conditions as the Board may specify, may permit a Participant to elect for, the payment of any Performance Cash Award to be deferred to a specified date or event. The Board may specify the form of payment of Performance Cash
Awards, which may be cash or other property, or may provide for a Participant to have the option for his or her Performance Cash Award, or such portion thereof as the Board may specify, to be paid in whole or in part in cash or other property.

 (iii)      Section 162(m)
Compliance.    Unless otherwise permitted in compliance with the requirements of Section 162(m) of the Code with respect to an Award intended to qualify as “performance-based compensation” thereunder, the
Committee shall establish the Performance Goals applicable to, and the formula for calculating the amount payable under, the Award no later than the earlier of (a) the date ninety (90) days after the commencement of the applicable
Performance Period, or (b) the date on which twenty-five (25%) of the Performance Period has elapsed, and in any event at a time when the achievement of the applicable Performance Goals remains substantially uncertain. Prior to the payment
of any compensation under an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee shall certify the extent to which any Performance Goals and any other material terms under such
Award have been satisfied (other than in cases where such relate solely to the increase in the value of the Common Stock). Notwithstanding satisfaction of any completion of any Performance Goals, to the extent specified at the time of grant of an
Award to “covered employees” within the meaning of Section 162(m) of the Code, the number of Shares, Options, cash or other benefits granted, issued, retainable and/or vested under an Award on account of satisfaction of such
Performance Goals may be reduced by the Committee on the basis of such further considerations as the Committee, in its sole discretion, shall determine. 
 (d)    Other Stock Awards.    Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including the
appreciation in value thereof may be granted either alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the Plan, the Board shall have sole and
complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards and
all other terms and conditions of such Other Stock Awards. 
  

	7.	 COVENANTS OF THE COMPANY. 

(a)    Availability of Shares.    During the terms of the Stock Awards,
the Company shall keep available at all times the number of shares of Common Stock reasonably required to satisfy such Stock Awards. 
 (b)    Securities Law Compliance.    The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this undertaking shall not require the Company to register under the Securities Act the
Plan, any Stock Award or any Common Stock issued or 

 
issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company
deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is
obtained. A Participant shall not be eligible for the grant of a Stock Award or the subsequent issuance of Common Stock pursuant to the Stock Award if such grant or issuance would be in violation of any applicable securities law. 

(c)    No Obligation to Notify or Minimize Taxes.    The Company shall
have no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company shall have no duty or obligation to warn or otherwise advise such holder of a pending termination
or expiration of a Stock Award or a possible period in which the Stock Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of a Stock Award to the holder of such Stock Award. 

 

	8.	 MISCELLANEOUS. 

 (a)    Use of Proceeds from Sales of Common Stock.    Proceeds from the sale of shares of Common Stock pursuant to Stock Awards shall constitute general
funds of the Company. 
 (b)    Corporate Action Constituting Grant of Stock
Awards.    Corporate action constituting a grant by the Company of a Stock Award to any Participant shall be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of
when the instrument, certificate, or letter evidencing the Stock Award is communicated to, or actually received or accepted by, the Participant. 
 (c)    Stockholder Rights.    No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of
Common Stock subject to such Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its terms, if applicable, and (ii) the issuance of the Common Stock subject to such
Stock Award has been entered into the books and records of the Company. 
 (d)    No
Employment or Other Service Rights.    Nothing in the Plan, any Stock Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto shall confer upon any Participant any
right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without
notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an
Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 
 (e)    Incentive Stock Option $100,000 Limitation.    To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common Stock
with respect to which 

 
Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and any Affiliates) exceeds one hundred thousand dollars
($100,000), the Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s).

 (f)    Investment Assurances.    The Company may require a
Participant, as a condition of exercising or acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or
to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the
merits and risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not
with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (A) the issuance of the shares upon the exercise or
acquisition of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the Company
that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary
or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 
 (g)    Withholding Obligations.    Unless prohibited by the terms of a Stock Award Agreement, the Company may, in its sole discretion, satisfy any federal,
state or local tax withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares
of Common Stock issued or otherwise issuable to the Participant in connection with the Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or
such lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise
payable to the Participant; or (v) by such other method as may be set forth in the Award Agreement. 

(h)    Electronic Delivery.    Any reference herein to a
“written” agreement or document shall include any agreement or document delivered electronically, filed publicly with at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet. 

(i)    Deferrals.    To the extent permitted by applicable law, the Board,
in its sole discretion, may determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for deferral
elections to be made by Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is still an

 
employee or otherwise providing services to the Company. The Board is authorized to make deferrals of Awards and determine when, and in what annual percentages, Participants may receive payments,
including lump sum payments, following the Participant’s termination of Continuous Service, and implement such other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law. 

(j)    Compliance with Section 409A.    To the extent that the Board
determines that any Award granted hereunder is subject to Section 409A of the Code, the Award Agreement evidencing such Award shall incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of
the Code. To the extent applicable, the Plan and Award Agreements shall be interpreted in accordance with Section 409A of the Code. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides
otherwise), if the Shares are publicly traded and a Participant holding an Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for purposes of Section 409A of the
Code, no distribution or payment of any amount shall be made upon a “separation from service” before a date that is six (6) months following the date of such Participant’s “separation from service” (as defined in
Section 409A of the Code without regard to alternative definitions thereunder) or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A of the
Code. 
  

	9.	 ADJUSTMENTS UPON CHANGES IN COMMON STOCK;
OTHER CORPORATE EVENTS. 

(a)    Capitalization Adjustments.    In the event of a Capitalization
Adjustment, the Board shall appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities that may be
issued pursuant to the exercise of Incentive Stock Options pursuant to Section 3(c), (iii) the class(es) and maximum number of securities that may be awarded to any person pursuant to Sections 3(d) and 6(c)(i), and (iv) the class(es)
and number of securities and price per share of stock subject to outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. 

(b)    Dissolution or Liquidation.    Except as otherwise provided in the
Stock Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the
Company’s right of repurchase) shall terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be
repurchased or reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service, provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become
fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.

 (c)    Corporate Transaction.    The following provisions
shall apply to Stock Awards in the event of a Corporate Transaction unless otherwise provided in the instrument evidencing 

 
the Stock Award or any other written agreement between the Company or any Affiliate and the holder of the Stock Award or unless otherwise expressly provided by the Board at the time of grant of a
Stock Award. In the event of a Corporate Transaction, then, notwithstanding any other provision of the Plan, the Board shall take one or more of the following actions with respect to Stock Awards, contingent upon the closing or completion of the
Corporate Transaction: 
 (i)        arrange for the surviving
corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not limited to, an award to
acquire the same consideration paid to the stockholders of the Company pursuant to the Corporate Transaction); 

(ii)       arrange for the assignment of any reacquisition or repurchase
rights held by the Company in respect of Common Stock issued pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company); 

(iii)     accelerate the vesting of the Stock Award (and, if applicable, the time at
which the Stock Award may be exercised) to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective
date of the Corporate Transaction), with such Stock Award terminating if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction; 

(iv)      arrange for the lapse of any reacquisition or repurchase rights held by
the Company with respect to the Stock Award; 
 (v)       cancel or
arrange for the cancellation of the Stock Award, to the extent not vested or not exercised prior to the effective time of the Corporate Transaction, in exchange for such cash consideration, if any, as the Board, in its sole discretion, may consider
appropriate; and 
 (vi)      make a payment, in such form as may be
determined by the Board equal to the excess, if any, of (A) the value of the property the Participant would have received upon the exercise of the Stock Award immediately prior to the effective time of the Corporate Transaction, over
(B) any exercise price payable by such holder in connection with such exercise. 
 The Board need not take
the same action or actions with respect to all Stock Awards or portions thereof or with respect to all Participants. 
 (d)    Change in Control.    A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in Control as may
be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, the following provisions shall govern:

 (i)      in the event of a Change in Control in which the surviving
corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) does not  

 
assume or continue the Stock Award or substitute a similar stock award for the Stock Award outstanding under the Plan (including, but not limited to, an award to acquire the same consideration
paid to the stockholders of the Company pursuant to the Change in Control), then with respect to Stock Awards that have not been assumed, continued or substituted that are held by Participants whose Continuous Service has not terminated prior to the
effective time of the Change in Control and who are (A) an Officer, (B) an Employee at the employee-director level (as determined by the Board), or (C) a Non-Employee Director (referred to as the “Current Senior
Participants”), the vesting of such Stock Awards (and, with respect to Options and Stock Appreciation Rights, the time when such Stock Awards may be exercised) shall be accelerated as to that number of shares that would otherwise have
vested under such Award in the ordinary course as of the date that is twelve (12) months after the effective time of the Change in Control, assuming the Current Senior Participant remained in Continuous Service for such twelve (12) month
period (with such accelerated vesting contingent upon the effectiveness of the Change in Control and effective as of the date the Board shall determine (or, if the Board shall not determine such a date, the date that is five (5) days prior to
the effective time of the Change in Control)), and such Stock Awards shall terminate if not exercised (if applicable) at or prior to the effective time of the Change in Control, and any reacquisition or repurchase rights held by the Company with
respect to such Stock Award will lapse as to that number of shares as to which such rights would otherwise have lapsed under such Award in the ordinary course as of the date that is twelve (12) months after the effective time of the Change in
Control, assuming the Current Senior Participant remained in Continuous Service for such twelve (12) month period (with such accelerated lapsing contingent upon the effectiveness of the Change in Control and effective as of the date the Board
shall determine (or, if the Board shall not determine such a date, the date that is five (5) days prior to the effective time of the Change in Control)). 
 (ii)      in the event of a Change in Control in which the surviving corporation or acquiring corporation (or its parent company) assumes or continues such outstanding
Stock Award or substitutes a similar stock award for such outstanding Stock Award, with respect to Stock Awards that have been assumed, continued or substituted that are held by Current Senior Participants, if any Current Senior Participant’s
Continuous Service terminates due to an involuntary termination (not including death or Disability) without Cause or due to a voluntary termination that is a Resignation for Good Reason, in either case on or within twelve (12) months after the
effective time of the Change in Control, and provided such termination of service is a “separation from service” as defined under Treasury Regulation Section 1.409A-1(h)), then, effective as of the date of the termination of
Continuous Service, the vesting of such Stock Award (and, with respect to Options and Stock Appreciation Rights, the time when such Stock Awards may be exercised) shall be accelerated as to that number of shares that would otherwise have vested in
the ordinary course under such Stock Award as of the date that is twelve (12) months after the termination of Continuous Service, assuming the Current Senior Participant remained in Continuous Service for such twelve (12) month period, and
any reacquisition or repurchase rights held by the Company with respect to such Stock Award held by such individual will lapse as to that number of shares as to which such rights would otherwise have lapsed under each such Stock Award in the
ordinary course as of the date that is twelve (12) months after the termination of Continuous Service, assuming the Current Senior Participant remained in Continuous Service for such twelve (12) month period. 

 (e)    Parachute
Payments.    If any payment or benefit the Participant would receive pursuant to a Change in Control from the Company or otherwise (“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 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 being subject to the Excise Tax or (y) the largest portion, up to and
including the total, of the Payment, whichever amount, 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
Participant’s receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute
payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order: reduction of cash payments; cancellation of accelerated vesting of Stock Awards other than Options; cancellation of accelerated
vesting of Options; and reduction of employee benefits. In the event that acceleration of vesting of Stock Award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of the
Participant’s applicable type of Stock Awards (i.e., earliest granted Stock Award cancelled last). 

The accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the
Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a
nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. The accounting firm engaged to make
the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the Participant and the Company within fifteen (15) calendar days after the date on which the Participant’s right to a Payment
is triggered (if requested at that time by the Participant or the Company) or such other time as requested by the Participant or the Company. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or
after the application of the Reduced Amount, it shall furnish the Participant and the Company with an opinion that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall
be final, binding and conclusive upon the Participant and the Company. 
  

	10.	 TERMINATION OR SUSPENSION OF THE PLAN.

 (a)    Plan Term.    The Board may
suspend or terminate the Plan at any time. Unless terminated sooner by the Board, the Plan shall automatically terminate on the day before the tenth (10th) anniversary of the earlier of (i) the date the Plan is adopted by the Board, or
(ii) the date the Plan is approved by the stockholders of the Company. No Awards may be granted under the Plan while the Plan is suspended or after it is terminated. 

 (b)    No Impairment of
Rights.    Suspension or termination of the Plan shall not impair rights and obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant. 

 

	11.	 EFFECTIVE DATE OF PLAN. 

The Plan shall become effective on the IPO Date, but no Stock Award shall be exercised (or, in the case of a Restricted
Stock Award, Restricted Stock Unit Award, Performance Stock Award, or Other Stock Award, shall be granted and no Performance Cash Award shall be settled) unless and until the Plan has been approved by the stockholders of the Company, which approval
shall be within twelve (12) months after the date the Plan is adopted by the Board. 
  

	12.	 CHOICE OF LAW. 

The law of the State of Delaware shall govern all questions concerning the construction, validity and interpretation of
this Plan, without regard to that state’s conflict of laws rules. 

13.    DEFINITIONS. As used in the Plan, the following definitions shall apply to the
capitalized terms indicated below: 
 (a)    “Affiliate”
means, at the time of determination, any “parent” or “subsidiary” of the Company as such terms are defined in Rule 405 of the Securities Act. The Board shall have the authority to determine the time or times at which
“parent” or “subsidiary” status is determined within the foregoing definition. 

(b)    “Award” means a Stock Award or a Performance Cash Award.

 (c)    “Award Agreement” means a written agreement between
the Company and a Participant evidencing the terms and conditions of an Award. 

(d)    “Board” means the Board of Directors of the Company.

 (e)    “Capitalization Adjustment” means any change that
is made in, or other events that occur with respect to, the Common Stock subject to the Plan or subject to any Stock Award after the Effective Date without the receipt of consideration by the Company through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or any similar
equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards No. 123 (revised). Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be treated as a
Capitalization Adjustment. 
 (f)    “Cause” shall have the
meaning ascribed to such term in any written agreement between the Participant and the Company defining such term and, in the absence of such agreement, such term shall mean, with respect to a Participant, the occurrence of any of the following
events that has a material negative impact on the business or reputation of the Company: (i) such Participant’s attempted commission of, or participation in, a fraud or act of dishonesty against the Company; (ii) such
Participant’s intentional, material violation of any 

 
contract or agreement between the Participant and the Company or of any statutory duty owed to the Company; (iii) such Participant’s unauthorized use or disclosure of the Company’s
confidential information or trade secrets; or (iv) such Participant’s gross misconduct. The determination that a termination of the Participant’s Continuous Service is either for Cause or without Cause shall be made by the Company, in
its sole discretion. Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding Awards held by such Participant shall have no effect upon any determination of
the rights or obligations of the Company or such Participant for any other purpose. 

(g)    “Change in Control” means the occurrence, in a single
transaction or in a series of related transactions, of any one or more of the following events: 

(i)      any Exchange Act Person becomes the Owner, directly or indirectly, of
securities of the Company representing more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the
foregoing, a Change in Control shall not be deemed to occur (A) on account of the acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any
affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity
securities, or (C) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or
other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by the
Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting
securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur; 
 (ii)      there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after the consummation of
such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more than fifty percent (50%) of the
combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of the parent of the surviving Entity in such
merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction; 

(iii)      there is consummated a sale, lease, exclusive license or other
disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries
to an Entity, more than fifty percent (50%) of the combined 

 
voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the
Company immediately prior to such sale, lease, license or other disposition; or 

(iv)      individuals who, on the date the Plan is adopted by the Board, are
members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of
any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member shall, for purposes of this Plan, be considered as a member of the Incumbent Board. 

Notwithstanding the foregoing or any other provision of this Plan, (A) the term Change in Control shall not include

Continuous Service; provided, however, if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, in its sole discretion, such Participant’s Continuous Service shall be
considered to have terminated on the date such Entity ceases to qualify as an 

 
Affiliate. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service shall be
considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or
their successors. Notwithstanding the foregoing, a leave of absence shall be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms
of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by law.

 NEOPHOTONICS CORPORATION 

2010 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 
 (INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK OPTION) 

Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement,
NeoPhotonics Corporation (the “Company”) has granted you an option under its 2010 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in
your Grant Notice at the exercise price indicated in your Grant Notice. Defined terms not explicitly defined in this Option Agreement but defined in the Plan shall have the same definitions as in the Plan. 

The details of your option are as follows: 

VESTING.  Subject to the limitations contained herein and the potential vesting
acceleration provisions set forth in Section 9 of the Plan, your option will vest as provided in your Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. 

NUMBER OF SHARES AND EXERCISE
PRICE.  The number of shares of Common Stock subject to your option and your exercise price per share referenced in your Grant Notice may be adjusted from time to time for Capitalization Adjustments. 

EXERCISE RESTRICTION FOR NON-EXEMPT
EMPLOYEES.  In the event that you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (i.e., a “Non-Exempt Employee”), and except as
otherwise provided in the Plan, you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant specified in your Grant Notice, notwithstanding any other provision of your
option. 
 EXERCISE PRIOR TO VESTING
(“EARLY EXERCISE”).  If permitted in your Grant Notice (i.e., the “Exercise Schedule” indicates “Early Exercise Permitted”) and subject to the provisions of your
option, you may elect at any time that is both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the unvested portion of your option; provided,
however, that: 
 a partial exercise of your option shall be deemed to cover first vested shares of Common
Stock and then the earliest vesting installment of unvested shares of Common Stock; 
 any shares of Common
Stock so purchased from installments that have not vested as of the date of exercise shall be subject to the purchase option in favor of the Company as described in the Company’s form of Early Exercise Stock Purchase Agreement; 

you shall enter into the Company’s form of Early Exercise Stock Purchase Agreement with a vesting schedule that
will result in the same vesting as if no early exercise had occurred; and 

 if your option is an Incentive Stock Option, then, to the extent that the
aggregate Fair Market Value (determined at the time of grant) of the shares of Common Stock with respect to which your option plus all other Incentive Stock Options you hold are exercisable for the first time by you during any calendar year (under
all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock
Options. 
 METHOD OF PAYMENT.  Payment of the
exercise price is due in full upon exercise of all or any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner permitted by your Grant Notice, which may include one or more
of the following: 
 Provided that at the time of exercise the Common Stock is publicly traded, pursuant to a
program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds. 
 Provided that at the time of exercise the
Common Stock is publicly traded, by delivery to the Company (either by actual delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are
valued at Fair Market Value on the date of exercise. “Delivery” for these purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your attestation of ownership of such
shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or
agreement restricting the redemption of the Company’s stock. 
 If the Option is a Nonstatutory Stock
Option, subject to the consent of the Company at the time of exercise, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the
largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or other payment from you to the extent of any remaining balance of the
aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued; provided further, however, that shares of Common Stock will no longer be outstanding under your option and will not be exercisable thereafter to the
extent that (1) shares are used to pay the exercise price pursuant to the “net exercise,” (2) shares are delivered to you as a result of such exercise, and (3) shares are withheld to satisfy tax withholding obligations.

 WHOLE SHARES.  You may exercise your option only for whole
shares of Common Stock. 
 SECURITIES LAW
COMPLIANCE.  Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such 

 
exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt
from the registration requirements of the Securities Act. The exercise of your option also must comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such
exercise would not be in material compliance with such laws and regulations. 

TERM.  You may not exercise your option before the commencement or after the expiration
of its term. The term of your option commences on the Date of Grant and expires, subject to the provisions of Section 5(h) of the Plan, upon the earliest of the following: 

immediately upon the termination of your Continuous Service for Cause; 

three (3) months after the termination of your Continuous Service for any reason other than Cause, your Disability
or death, provided that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above relating to “Securities Law Compliance,” your option shall not
expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; and if (i) you are a Non-Exempt Employee, (ii) your
Continuous Service terminates within six (6) months after the Date of Grant specified in your Grant Notice, and (iii) you have vested in a portion of your option at the time of your termination of Continuous Service, your option shall not
expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date of Grant specified in your Grant Notice or (B) the date that is three (3) months after the termination of your Continuous
Service, or (y) the Expiration Date; 
 twelve (12) months after the termination of your Continuous
Service due to your Disability; 
 eighteen (18) months after your death if you die either during your
Continuous Service or within three (3) months after your Continuous Service terminates for any reason other than Cause; 
 the Expiration Date indicated in your Grant Notice; or 
 the day
before the tenth (10th) anniversary of the Date of Grant. 
 If your option is an Incentive Stock Option,
note that to obtain the federal income tax advantages associated with an Incentive Stock Option, the Code requires that at all times beginning on the date of grant of your option and ending on the day three (3) months before the date of your
option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but
cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise
your option more than three (3) months after the date your employment with the Company or an Affiliate terminates. 

 EXERCISE. 

You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so
permits) during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require. 
 By exercising your option you agree
that, as a condition to any exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise
of your option, (2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. 

If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in
writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one
(1) year after such shares of Common Stock are transferred upon exercise of your option. 

TRANSFERABILITY.  Except as otherwise provided in this Section 10, your option is
not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. 
 Certain Trusts.  Upon receiving written permission from the Board or its duly authorized designee, you may transfer your option to a trust if you are considered to be the sole beneficial
owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust, provided that you and the trustee enter into transfer and other agreements required by the Company. 

Domestic Relations Orders.  Upon receiving written permission from the Board or its duly authorized
designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your option pursuant to a domestic relations order that contains the information required by the Company
to effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this option with the Company prior to finalizing the domestic relations order to help ensure the required information is contained within the domestic
relations order. If this option is an Incentive Stock Option, this option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 
 Beneficiary Designation.  Upon receiving written permission from the Board or its duly authorized designee, you may, by delivering written notice to the Company, in a form provided by or
otherwise satisfactory to the Company and any broker designated by the Company to effect option exercises, designate a third party who, in the event of your death, shall thereafter be entitled to exercise this option and receive the Common Stock or
other consideration resulting from such exercise. In the absence of such a designation, your executor or administrator 

 
of your estate shall be entitled to exercise this option and receive, on behalf of your estate, the Common Stock or other consideration resulting from such exercise. 

OPTION NOT A SERVICE
CONTRACT.  Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an
Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers or Employees to continue any
relationship that you might have as a Director or Consultant for the Company or an Affiliate. 

WITHHOLDING OBLIGATIONS. 

At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you
hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as
promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with
the exercise of your option. 
 Upon your request and subject to approval by the Company, in its sole
discretion, and in compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock
having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option as a
liability for financial accounting purposes). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be
permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to
accelerate the determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined
as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are
satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock unless such obligations are
satisfied. 
 TAX CONSEQUENCES.  You hereby agree
that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You shall not make any claim against the Company, or any of its Officers, Directors,

 
Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the
Code only if the exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated
with the option. 
 NOTICES.  Any notices provided for in your option or the
Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at
the last address you provided to the Company. 
 GOVERNING PLAN
DOCUMENT.  Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which
may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control.

 ATTACHMENT I 

NEOPHOTONICS CORPORATION 

2010 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT AGREEMENT 

Pursuant to the Restricted Stock Unit Grant Notice (the “Grant Notice”) and this Restricted Stock
Unit Agreement (the “Agreement”) and in consideration of your services, NeoPhotonics Corporation (the “Company”) has awarded you a Restricted Stock Unit award (the “Award”)
under its 2010 Equity Incentive Plan (the “Plan”). Your Award is granted to you effective as of the Date of Grant set forth in the Grant Notice for this Award and is subject to the terms set forth herein. Defined terms not
explicitly defined in this Agreement shall have the same meanings given to them in the Plan. In the event of any conflict between the terms in this Agreement and the Plan, the terms of the Plan shall control. The details of your Award, in addition
to those set forth in the Grant Notice and the Plan, are as follows. 
 GRANT
OF THE AWARD.  This Award represents the right to be issued on a future date the number of shares of the Company’s Common Stock as indicated in the Grant Notice. As of the Date of
Grant, the Company will credit to a bookkeeping account maintained by the Company for your benefit (the “Account”) the number of shares of Common Stock subject to the Award. This Award was granted in consideration of your
services to the Company. Except as otherwise provided herein, you will not be required to make any payment to the Company (other than past and future services to the Company) with respect to your receipt of the Award, the vesting of the shares or
the delivery of the underlying Common Stock. 
 VESTING.  Subject to the
limitations contained herein and the potential vesting acceleration provisions set forth in Section 9(d) of the Plan, your Award will vest, if at all, in accordance with the vesting schedule provided in the Grant Notice, provided that vesting
will cease upon the termination of your Continuous Service. Upon such termination of your Continuous Service, the shares credited to the Account that were not vested on the date of such termination will be forfeited at no cost to the Company and you
will have no further right, title or interest in or to such underlying shares of Common Stock. 

NUMBER OF SHARES. 

The number of units/shares subject to your Award may be adjusted from time to time for Capitalization Adjustments, as
provided in the Plan. 
 Any shares, cash or other property that becomes subject to the Award pursuant to this
Section 3, if any, shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other shares covered by your Award. 

Notwithstanding the provisions of this Section 3, no fractional shares or rights for fractional shares of Common
Stock shall be created pursuant to this Section 3. The Board shall, 

  
 1. 

 
in its discretion, determine an equivalent benefit for any fractional shares or fractional shares that might be created by the adjustments referred to in this Section 3. 

SECURITIES LAW COMPLIANCE.  You may not be issued any
shares under your Award unless either (a) the shares are registered under the Securities Act; or (b) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Your Award also
must comply with other applicable laws and regulations governing the Award, and you will not receive such shares if the Company determines that such receipt would not be in material compliance with such laws and regulations. 

TRANSFER RESTRICTIONS.  Prior to the time that shares of Common Stock have
been delivered to you, you may not transfer, pledge, sell or otherwise dispose of this Award or the shares issuable in respect of your Award, except as expressly provided in this Section 5. For example, you may not use shares that may be issued
in respect of your Restricted Stock Units as security for a loan. The restrictions on transfer set forth herein will lapse upon delivery to you of shares in respect of your vested Restricted Stock Units. 

Death.  Your Award is transferable by will and by the laws of descent and distribution. In addition,
upon receiving written permission from the Board or its duly authorized designee, you may, by delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company and any broker designated by the Company to effect
transactions under the Plan, designate a third party who, in the event of your death, shall thereafter be entitled to receive any distribution of Common Stock or other consideration to which you were entitled at the time of your death pursuant to
this Agreement. In the absence of such a designation, your executor or administrator of your estate shall be entitled to receive, on behalf of your estate, such Common Stock or other consideration. 

Certain Trusts.  Upon receiving written permission from the Board or its duly authorized designee, you
may transfer your Award to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the Award is held in the trust, provided that you and the trustee enter into
transfer and other agreements required by the Company. 
 Domestic Relations Orders.  Upon
receiving written permission from the Board or its duly authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your Award or your right to receive
the distribution of Common Stock or other consideration thereunder, pursuant to a domestic relations order that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any
division of this Award with the Company prior to finalizing the domestic relations order to help ensure the required information is contained within the domestic relations order. 

DATE OF ISSUANCE. 

The Company will deliver to you a number of shares of the Company’s Common Stock equal to the number of vested
shares subject to your Award, including any additional shares received pursuant to Section 3 above that relate to those vested shares on the applicable 

  
 2. 

 
vesting date(s). However, if a scheduled delivery date falls on a date that is not a business day, such delivery date shall instead fall on the next following business day. 

Notwithstanding the foregoing, in the event that (i) you are subject to the Company’s policy permitting
certain individuals to sell shares only during certain “window” periods, in effect from time to time or you are otherwise prohibited from selling shares of the Company’s Common Stock in the public market and any shares covered by your
Award are scheduled to be delivered on a day (the “Original Distribution Date”) that does not occur during an open “window period” applicable to you, as determined by the Company in accordance with such policy, or
does not occur on a date when you are otherwise permitted to sell shares of the Company’s common stock on the open market, and (ii) the Company elects not to satisfy its tax withholding obligations by withholding shares from your
distribution, then such shares shall not be delivered on such Original Distribution Date and shall instead be delivered on the first (1st) business day of the next occurring open “window period” applicable to you pursuant to such
policy (regardless of whether you are still providing Continuous Service at such time) or the next business day when you are not prohibited from selling shares of the Company’s Common Stock in the open market, as applicable, but in no event
later than the fifteenth (15th) day of the third (3rd) calendar month of the calendar year following the calendar year in which the shares of Common Stock originally became vested. The form of such delivery (e.g., a stock
certificate or electronic entry evidencing such shares) shall be determined by the Company. In all cases, the delivery of shares under this Award is intended to comply with Treasury Regulation Section 1.409A-1(b)(4) and shall be construed and
administered in such a manner. If it is determined that the delivery of shares under this Award does not comply with Treasury Regulation Section 1.409A-1(b)(4), shares issued under this Award shall be delivered not later than December 31
of the calendar year in which such shares originally became vested. 

DIVIDENDS.  You shall receive no benefit or adjustment to your Award with respect to any
cash dividend, stock dividend or other distribution that does not result from a Capitalization Adjustment; provided, however, that this sentence shall not apply with respect to any shares of Common Stock that are delivered to you in
connection with your Award after such shares have been delivered to you. 
 RESTRICTIVE
LEGENDS.  The shares issued under your Award shall be endorsed with appropriate legends as determined by the Company. 
 AWARD NOT A SERVICE CONTRACT. 
 Your Continuous Service with the Company or an Affiliate is not for any specified term and may be terminated by you or by the Company or an Affiliate at any time, for any reason, with or without cause and
with or without notice. Nothing in this Agreement (including, but not limited to, the vesting of your Award pursuant to the schedule set forth in Section 2 herein or the issuance of the shares subject to your Award), the Plan or any
covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan shall: (i) confer upon you any right to continue in the employ of, or affiliation with, the Company or an Affiliate; (ii) constitute any
promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or condition of employment or affiliation; (iii) confer any right or benefit
under this Agreement or the 

  
 3. 

 
Plan unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the Company of the right to terminate you at will and without regard to
any future vesting opportunity that you may have. 
 The right to continue vesting in the Award pursuant to
Section 2 and the schedule set forth in the Grant Notice is earned only by continuing as an employee, director or consultant at the will of the Company (not through the act of being hired, being granted this Award or any other award or benefit)
and that the Company has the right to reorganize, sell, spin-out or otherwise restructure one or more of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). Such a
reorganization could result in the termination of your Continuous Service, or the termination of Affiliate status of your employer and the loss of benefits available to you under this Agreement, including but not limited to, the termination of the
right to continue vesting in the Award. This Agreement, the Plan, the transactions contemplated hereunder and the vesting schedule set forth herein or any covenant of good faith and fair dealing that may be found implicit in any of them do not
constitute an express or implied promise of continued engagement as an employee or consultant for the term of this Agreement, for any period, or at all, and shall not interfere in any way with your right or the Company’s right to terminate your
Continuous Service at any time, with or without cause and with or without notice. 

WITHHOLDING OBLIGATIONS. 

On or before the time you receive a distribution of the shares subject to your Award, or at any time thereafter as
requested by the Company, you hereby authorize any required withholding from the Common Stock issuable to you and/or otherwise agree to make adequate provision in cash for any sums required to satisfy the federal, state, local and foreign tax
withholding obligations of the Company or any Affiliate which arise in connection with your Award (the “Withholding Taxes”). Additionally, the Company may, in its sole discretion, satisfy all or any portion of the Withholding
Taxes obligation relating to your Award by any of the following means or by a combination of such means: (i) withholding from any compensation otherwise payable to you by the Company; (ii) causing you to tender a cash payment;
(iii) permitting you to enter into a “same day sale” commitment with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”) whereby you irrevocably elect to sell a
portion of the shares to be delivered under the Award to satisfy the Withholding Taxes and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its Affiliates;
or (iv) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to you in connection with the Award with a Fair Market Value (measured as of the date shares of Common Stock are issued to pursuant to
Section 6) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares of Common Stock so withheld shall not exceed the amount necessary to satisfy the Company’s required tax withholding obligations
using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income. 

Unless the tax withholding obligations of the Company and/or any Affiliate are satisfied, the Company shall have no
obligation to deliver to you any Common Stock. 

  
 4. 

 In the event the Company’s obligation to withhold arises prior to the
delivery to you of Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold the
Company harmless from any failure by the Company to withhold the proper amount. 
 UNSECURED
OBLIGATION.  Your Award is unfunded, and as a holder of a vested Award, you shall be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares pursuant to this
Agreement. You shall not have voting or any other rights as a stockholder of the Company with respect to the shares to be issued pursuant to this Agreement until such shares are issued to you pursuant to Section 6 of this Agreement. Upon such
issuance, you will obtain full voting and other rights as a stockholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary
relationship between you and the Company or any other person. 
 OTHER
DOCUMENTS.  You hereby acknowledge receipt or the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus. In addition,
you acknowledge receipt of the Company’s policy permitting certain individuals to sell shares only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

NOTICES.  Any notices provided for in your Award or the Plan shall be given in writing
and shall be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the
Company. Notwithstanding the foregoing, the Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this Award by electronic means or to request your consent to participate in the Plan by
electronic means. You hereby consent to receive such documents by electronic delivery and, if requested, to agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party
designated by the Company. 
 MISCELLANEOUS. 

The rights and obligations of the Company under your Award shall be transferable to any one (1) or more persons or
entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. Your rights and obligations under your Award may only be assigned with the prior written consent of
the Company. 
 You agree upon request to execute any further documents or instruments necessary or desirable
in the sole determination of the Company to carry out the purposes or intent of your Award. 
 You acknowledge
and agree that you have reviewed your Award in its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting your Award, and fully understand all provisions of your Award. 

  
 5. 

 This Agreement shall be subject to all applicable laws, rules, and
regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. 
 All obligations of the Company under the Plan and this Agreement shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase,
merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. 

GOVERNING PLAN DOCUMENT.  Your Award is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your Award, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan.
Except as expressly provided herein, in the event of any conflict between the provisions of your Award and those of the Plan, the provisions of the Plan shall control. 

SEVERABILITY.  If all or any part of this Agreement or the Plan is declared by any court
or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so
declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

EFFECT ON OTHER EMPLOYEE BENEFIT
PLANS.  The value of the Award subject to this Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating the Employee’s benefits under any employee benefit
plan sponsored by the Company or any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans.

 CHOICE OF LAW.  The interpretation, performance
and enforcement of this Agreement will be governed by the law of the state of Delaware without regard to such state’s conflicts of laws rules. 
 AMENDMENT.  This Agreement may not be modified, amended or terminated except by an instrument in writing, signed by you and by a duly authorized representative of the
Company. Notwithstanding the foregoing, this Agreement may be amended solely by the Board by a writing which specifically states that it is amending this Agreement, so long as a copy of such amendment is delivered to you, and provided that, except
as otherwise expressly provided in the Plan, no such amendment adversely affecting your rights hereunder may be made without your written consent. Without limiting the foregoing, the Board reserves the right to change, by written notice to you, the
provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that
any such change shall be applicable only to rights relating to that portion of the Award which is then subject to restrictions as provided herein. 

  
 6. 

 COMPLIANCE WITH
SECTION 409A OF THE CODE.  This Award is intended to comply with the “short-term deferral” rule set forth in
Treasury Regulation Section 1.409A-1(b)(4). Notwithstanding the foregoing, if it is determined that the Award fails to satisfy the requirements of the short-term deferral rule and is otherwise deferred compensation subject to Section 409A,
and if you are a “Specified Employee” (within the meaning set forth Section 409A(a)(2)(B)(i) of the Code) as of the date of your separation from service (within the meaning of Treasury Regulation Section 1.409A-1(h)), then the
issuance of any shares that would otherwise be made upon the date of the separation from service or within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will instead be issued in a lump sum on the
date that is six (6) months and one day after the date of the separation from service, with the balance of the shares issued thereafter in accordance with the original vesting and issuance schedule set forth above, but if and only if such delay
in the issuance of the shares is necessary to avoid the imposition of taxation on you in respect of the shares under Section 409A of the Code. Each installment of shares that vests is intended to constitute a “separate payment” for
purposes of Treasury Regulation Section 1.409A-2(b)(2). 
 NO OBLIGATION
