(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).

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

(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.



---

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.

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.

impair rights and obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant.

which approval shall be within twelve (12) months after the date the Plan is adopted by the Board.

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

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

Notwithstanding the foregoing or any other provision of this Plan, (A) the term Change in Control shall not include a sale of
assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any

offer or the sale of the Companys securities to such person.

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

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.Subject to adjustment and the terms and conditions as provided herein and in the Plan, 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 additional Restricted Stock Units and 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 Restricted Stock Units and any 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. Any fraction of a share will be rounded down to the nearest whole share.

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, nor may you transfer, pledge, sell or otherwise dispose of such shares. 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.

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 issuance of shares in respect of the Restricted Stock Units
is intended to comply with Treasury Regulation Section 1.409A-1(b)(4) and shall be construed and administered in such a manner.

Subject to the satisfaction of the withholding obligations set forth in Section 10 of this Agreement, in the event one or more Restricted Stock Units vests, the Company shall issue to you one share
of Common Stock for each Restricted



---

Stock Unit that vests on the applicable vesting dates. The issuance date determined by this paragraph is referred to as the Original Issuance Date. If the Original
Issuance Date falls on a date that is not a business day, delivery shall instead occur on the next following business day.

Notwithstanding the foregoing, if (i) the Original Issuance Date does not occur (1) during an open window period applicable to you, as determined by the Company in accordance with
the Companys then-effective policy on trading in Company securities, or (2) on a date when you are otherwise permitted to sell shares of Common Stock on an established stock exchange or stock market, and (ii) the Company elects,
prior to the Original Issuance Date, (1) not to satisfy the tax withholding obligations described in Section 10 by withholding shares of Common Stock from the shares otherwise due, on the Original Issuance Date, to you under this Award,
and (2) not to permit you to enter into a same day sale commitment with a broker-dealer pursuant to Section 10 of this Agreement (including but not limited to a commitment under a previously established Company-approved 10b5-1
trading plan), then such shares shall not be delivered on such Original Issuance Date and shall instead be delivered on the first business day of the next occurring open window period applicable to you or the next business day when you are not
prohibited from selling shares of the Companys Common Stock in the open public market, but in no event later than December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable year in
which the Original Issuance Date occurs), or, if permitted in a manner that complies with Treasury Regulation Section 1.409A-1(b)(4), in no event later than the date that is the 15th day of the third calendar month of the year following the
year in which the shares of Common Stock under this Award are no longer subject to a substantial risk of forfeiture within the meaning of Treasury Regulation Section 1.409A-1(d).

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 or service 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 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 each vesting date, and 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 or an Affiliate 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 or an Affiliate;
(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 (or Affiliate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.



---

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 or other cash or property
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.



---

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.

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).
