1. General 
 1.1
Purpose. Optichron has adopted the Plan as contemplated by Section 6.8(e) of the Merger Agreement. Optichron and NetLogic, by means of the Plan, seek to retain the services of the group of persons eligible to receive Awards, and to
provide incentives for such persons to exert maximum efforts for the success of Optichron, NetLogic and any Affiliate. 
 1.2
Available Awards. The purpose of the Plan is to provide a means by which eligible recipients of Awards may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Restricted Stock Units.

Directors of Optichron at least two Business Days prior to the Closing. Pursuant to the terms of the Merger Agreement, at the Merger Effective Time NetLogic shall assume the Plan and all Awards then-outstanding under the Plan, and such assumed
Awards shall be converted into restricted stock unit awards to acquire, on substantially the same terms and conditions as were applicable under such Award, the number of shares of NetLogic common stock rounded down to the nearest whole share,
determined in accordance with the terms of the Merger Agreement. No Awards may be granted under the Plan following the Merger Effective Time.

 4. Administration 

In all events the Plan shall be administered by the Board or Committee. The Plan shall be administered by the Committee, provided,
however, that at any time and on any one or more occasions the Board may itself exercise any of the powers and responsibilities assigned the Committee under the Plan and when so acting shall have the benefit of all of the provisions of the Plan
pertaining to the Committee’s exercise of its authorities hereunder. Subject to the provisions of the Plan, including Section 1.3 hereof, the Committee shall have complete authority, in its discretion, to make or to select the manner of
making all determinations with respect to each Award to be granted by the Company under the Plan. All Awards of Stock or which otherwise entitle the Award recipient to acquire any shares of Stock shall be made from the authorized but unissued shares
of Stock of the Company. Subject to the provisions of the Plan, the Committee shall have complete authority to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to it, and to make all other determinations necessary
or advisable for the administration of the Plan including, but not limited to, the cancellation, amendment, renewal, or reclassification of outstanding Awards, subject to the provisions of Section 13, and to correct any defect, supply any
omission or reconcile any inconsistency in the Plan, any Award and any Award Agreement. In addition, the Committee may amend the Plan or Awards in order to bring such arrangements into compliance with Section 409A of the Code, subject to the
limitations, if any, of applicable law. Except as provided above, rights under any Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (1) the Company requests the consent of the affected
Participant, and (2) such Participant consents in writing. The Committee’s determinations made in good faith on matters referred to in the Plan shall be final, binding and conclusive on all persons having or claiming any interest under the
Plan or an Award made pursuant to hereto. 
 5. Authorization of Grants 

5.1 Eligibility. The persons eligible to receive Awards under the Plan are Continuing Employees. 

5.2 General Terms of Awards. Each grant of an Award shall be subject to all applicable terms and conditions of the Plan (including
but not limited to any specific terms and conditions applicable to the Award set out in the following Section), and such other terms and conditions, not inconsistent with the terms of the Plan, as the Committee may prescribe. No prospective
Participant shall have any rights with respect to an Award, unless and until such Participant has executed an Award agreement evidencing the Award, delivered a fully executed copy thereof to the Company, and otherwise complied with the applicable
terms and conditions of such Award. 
 5.3 Effect of Termination of Employment, Disability or Death. 

(a) Termination of Employment, Etc. Unless otherwise provided in the terms of an Award Agreement, if the Participant’s
employment or other association with the Company or its Affiliates ends for any reason, including because of the Participant’s employer ceasing to be an Affiliate, any outstanding Award of the Participant shall be forfeited on the terms
specified in the applicable Award Agreement. Military or sick leave or other personal leave approved by an authorized representative of the Company shall not be deemed a termination of employment or other association, provided that it does
not exceed the longer of 90 days or the period during which the absent Participant’s reemployment rights, if any, are guaranteed by statute or by contract. 

  
 4 

 5.4 Transferability of Awards. Except as otherwise provided in this Section 5.4,
Awards shall not be transferable, and no Award or interest therein may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. All of a Participant’s rights
in any Award may be exercised during the life of the Participant only by the Participant or the Participant’s legal representative 
 6.
Specific Terms of Awards 
 6.1 Restricted Stock Units. 

(a) Character. Each Restricted Stock Unit shall entitle the recipient to a share of Stock at a close of such Restriction Period as
established by Optichron on the date of grant and provided for in the applicable Award Agreement. Subject to applicable law (including Section 409A of the Code), the Restriction Period may be shortened at any time by the Committee on such basis
as it deems appropriate. 
 (b) Form and Timing of Payment. Payment of earned Restricted Stock Units shall be made in a
single lump sum following the close of the applicable Restriction Period unless the applicable Award Agreement provides for a later settlement date in compliance with Section 409A of the Code. At the discretion of the Committee, Participants
may be entitled to receive payments equivalent to any dividends declared with respect to Stock referenced in grants of Restricted Stock Units but only following the close of the applicable Restriction Period and then only if the underlying Stock
shall have been earned. Unless the Committee shall provide otherwise, any such dividend equivalents shall be paid, if at all, without interest or other earnings. 
 6.2 Awards to Participants Outside the United States. The Committee may modify the terms of any Award under the Plan, granted to a Participant who is, at the time of grant or during the term of the
Award, resident or primarily employed outside of the United States in any manner deemed by the Committee to be necessary or appropriate in order that the Award shall conform to laws, regulations, and customs of the country in which the Participant
is then resident or primarily employed, or so that the value and other benefits of the Award to the Participant, as affected by foreign tax laws and other restrictions applicable as a result of the Participant’s residence or employment abroad,
shall be comparable to the value of such an Award to a Participant who is resident or primarily employed in the United States. The Committee may establish supplements to, or amendments, restatements, or alternative versions of, the Plan for the
purpose of granting and administrating any such modified Award. 
 7. Adjustment Provisions 

7.1 Adjustment for Corporate Actions. All of the share numbers set forth in the Plan reflect the capital structure of Optichron as
of immediately prior to the Closing, and shall be subject to adjustment as provided in Section 6.8(e) of the Merger Agreement as of the Merger Effective Time in connection with the assumption of the Plan and Awards by NetLogic. Subject to
Section 7.2, if subsequent to such adjustment the outstanding shares of Stock (or any other securities covered by the Plan by reason of the prior application of this Section) are increased, decreased, or exchanged for a different number or kind
of shares or other securities, or if additional shares or new or different shares or other securities are distributed with respect to shares of Stock, through merger, consolidation, sale of all or substantially all the property of the Company,
reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar distribution with respect to such shares of Stock, an appropriate and proportionate adjustment shall be made in (i) the
numbers and kinds of shares or other securities subject to the then outstanding Awards, and (ii) the number of shares reserved for issuance under the Plan pursuant to Section 3. 

7.2 Treatment in Certain Acquisitions. 
 (a) Subject to any provisions of then outstanding Awards granting greater rights to the holders thereof, in the event of a Change of Control or an Acquisition that constitutes a Change of Control in which
outstanding Awards are not Accelerated in full, any then outstanding Awards shall nevertheless Accelerate in full if not assumed or replaced by comparable Awards referencing shares of the capital stock of the successor or acquiring entity or
the entity in control of such successor or acquiring entity, and thereafter (or after a reasonable period 

  
 5 

 
following the Acquisition, as determined by the Committee) terminate. As to any one or more outstanding Awards which are not otherwise Accelerated in full by reason of such Acquisition, the
Committee may also, either in advance of an Acquisition or at the time thereof and upon such terms as it may deem appropriate, provide for the Acceleration of such outstanding Awards in the event that the employment of the Participants should
subsequently terminate following the Acquisition. Each outstanding Award that is assumed in connection with an Acquisition, or is otherwise to continue in effect subsequent to the Acquisition, will be appropriately adjusted, immediately after the
Acquisition, as to the number and class of securities and other relevant terms in accordance with Section 7.1. 
 (b) For
the purposes of this Section 7.2, an Award shall be considered assumed or replaced by a comparable Award if, following the Acquisition, the Award confers the right to purchase, for each share of Stock subject to the Award immediately prior to
the Acquisition, the consideration (whether stock, cash or other securities or property) received in the Acquisition by holders of Stock on the effective date of the Acquisition (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if such consideration received in the Acquisition was not solely common stock of the successor corporation or its Parent or
Subsidiary, the Committee may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Award for each share of Stock subject to the Award to be solely common stock of the successor
corporation or its Parent or Subsidiary equal in fair market value to the per share consideration received by holders of Stock in the Acquisition. 
 7.3 Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. In the event of any corporate action (other than the transactions contemplated by the Merger Agreement) not
specifically covered by the preceding sections, including, but not limited to, an extraordinary cash distribution on Stock, a corporate separation or other reorganization or liquidation, the Committee may make such adjustment of outstanding Awards
and their terms, if any, as it, in its sole discretion, may deem equitable and appropriate in the circumstances. The Committee may make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or
nonrecurring events (including, without limitation, the events described in this Section 7.3) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations, or accounting principles, whenever the
Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. 

7.4 Related Matters. Any adjustment in Awards made pursuant to this Section 7 shall be determined and made, if at all, by the
Committee and shall include any correlative modification of terms, including of rates of vesting, which the Committee may deem necessary or appropriate so as to ensure the rights of the Participants in their respective Awards are not substantially
diminished nor enlarged as a result of the adjustment and corporate action other than as expressly contemplated in this Section 7. No fraction of a share shall be deliverable upon settlement, but in the event any adjustment hereunder of the
number of shares covered by an Award shall cause such number to include a fraction of a share, such number of shares shall be adjusted to the nearest smaller whole number of shares. 
 8. Settlement of Awards 
 8.1 In General. Awards may be settled in
cash, Stock, or other Awards, or a combination thereof, as determined by the Committee at or after grant and subject to any contrary terms contained in an Award Agreement. The Committee may not require settlement of any Award in Stock pursuant to
the immediately preceding sentence to the extent issuance of such Stock would be prohibited or unreasonably delayed by reason of any other provision of the Plan. 
 8.2 Violation of Law. Notwithstanding any other provision of the Plan or the relevant Award Agreement, if, at any time, in the reasonable opinion of the Company, the issuance of shares of Stock
covered by an Award may constitute a violation of law, then the Company may delay such issuance and the delivery of a certificate for such shares until (i) approval shall have been obtained from such governmental agencies, other than the
Securities and Exchange Commission, as may be required under any applicable law, rule, or regulation and (ii) in the case where such issuance would constitute a violation of a law administered by or a regulation of the Securities and Exchange
Commission, one of the following conditions shall have been satisfied: 
 (a) the shares are at the time of the issue of such
shares effectively registered under the Securities Act; or 

  
 6 

 (b) the Company shall have determined, on such basis as it deems appropriate (including an
opinion of counsel in form and substance satisfactory to the Company) that the sale, transfer, assignment, pledge, encumbrance or other disposition of such shares or such beneficial interest, as the case may be, does not require registration under
the Securities Act or any applicable State securities laws. 
 The Company shall make all reasonable efforts to bring about the occurrence of
said events 
 8.3 Corporate Restrictions on Rights in Stock. Any Stock to be issued pursuant to Awards granted under the
Plan shall be subject to all restrictions upon the transfer thereof which may be now or hereafter imposed by the charter, certificate or articles, or by laws, of the Company. 
 8.4 Investment Representations. The Company shall be under no obligation to issue any shares covered by any Award unless the shares to be issued pursuant to Awards granted under the Plan have been
effectively registered under the Securities Act, or the Participant shall have made such written representations to the Company (upon which the Company believes it may reasonably rely) as the Company may deem necessary or appropriate for purposes of
confirming that the issuance of such shares will be exempt from the registration requirements of the Securities Act and any applicable state securities laws and otherwise in compliance with all applicable laws, rules and regulations, including but
not limited to that the Participant is acquiring the shares for his or her own account for the purpose of investment and not with a view to, or for sale in connection with, the distribution of any such shares. 

8.5 Registration. 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 Awards and to issue and sell shares of Stock upon settlement of the Awards. Pursuant to Section 6.8(g) of the Merger Agreement, NetLogic has agreed to file a registration statement on Form S-8 (or any
successor form) or another appropriate form with respect to all shares of Stock to be issued pursuant to the Awards. The Company may require from each recipient of an Award, or each holder of shares of Stock acquired pursuant to the Plan, such
information in writing for use in any registration statement, prospectus, preliminary prospectus or offering circular as is reasonably necessary for that purpose and may require reasonable indemnity to the Company and its officers and directors from
that holder against all losses, claims, damage and liabilities arising from use of the information so furnished and caused by any untrue statement of any material fact therein or caused by the omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made. 
 8.6 Placement of Legends; Stop Orders; etc. Each share of Stock to be issued pursuant to Awards granted under the Plan may bear a reference to the investment representation made in accordance with
Section 8.4 in addition to any other applicable restriction under the Plan, the terms of the Award and, if applicable, to the fact that no registration statement has been filed with the Securities and Exchange Commission in respect to such
shares of Stock. All certificates for shares of Stock or other securities delivered under the Plan shall be subject to such stock transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other
requirements of any stock exchange upon which the Stock is then listed, and any applicable federal or state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such
restrictions. 
 8.7 Tax Withholding. Whenever shares of Stock are issued or to be issued pursuant to Awards granted
under the Plan, the Company shall have the right to require the recipient to remit to the Company an amount sufficient to satisfy federal, state, local or other withholding tax requirements if, when, and to the extent required by law (whether so
required to secure for the Company an otherwise available tax deduction or otherwise) prior to the delivery of any certificate or certificates for such shares. The obligations of the Company under the Plan shall be conditional on satisfaction of all
such withholding obligations and the Company shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the recipient of an Award. However, in such cases Participants may elect,
subject to the approval of the Committee, to satisfy an applicable withholding requirement, in whole or in part, by having the Company withhold shares to satisfy their tax 

  
 7 

 
obligations. Participants may only elect to have shares withheld having a Market Value on the date the tax is to be determined equal to the minimum statutory total tax which could be imposed on
the transaction. All elections shall be irrevocable, made in writing, signed by the Participant, and shall be subject to any restrictions or limitations that the Committee deems appropriate. 
 9. Reservation of Stock 
 The Company shall at all times during the term of
the Plan and any outstanding Awards granted hereunder reserve or otherwise keep available such number of shares of Stock as will be sufficient to satisfy the requirements of the Plan (if then in effect) and the Awards and shall pay all fees and
expenses necessarily incurred by the Company in connection therewith. 
 10. Limitation of Rights in Stock; No Special Service Rights

 A Participant shall not be deemed for any purpose to be a stockholder of the Company with respect to any of the shares of
Stock subject to an Award, unless and until a certificate shall have been issued therefor and delivered to the Participant or his agent, or if uncertificated shares are to be issued, until such shares have been registered in the name of the
Participant on the books of the transfer agent and registrar of the Stock. Any Stock to be issued pursuant to Awards granted under the Plan shall be subject to all restrictions upon the transfer thereof which may be now or hereafter imposed by the
certificate of incorporation and the bylaws of the Company. Nothing contained in the Plan or in any Award Agreement shall confer upon any recipient of an Award any right with respect to the continuation of his or her employment or other association
with the Company (or any Affiliate), or interfere in any way with the right of the Company (or any Affiliate), subject to the terms of any separate employment or consulting agreement or provision of law or certificate of incorporation or by laws to
the contrary, at any time to terminate such employment or consulting agreement or to increase or decrease, or otherwise adjust, the other terms and conditions of the recipient’s employment or other association with the Company and its
Affiliates. 
 11. Unfunded Status of Plan 
 The Plan is intended to constitute an “unfunded” plan for incentive compensation, and the Plan is not intended to constitute a plan subject to the provisions of the Employee Retirement Income
Security Act of 1974, as amended. With respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company. In its
sole discretion, the Committee may authorize the creation of trusts or other arrangements to meet the obligations created under the Plan to deliver Stock or payments with respect to Awards hereunder, provided, however, that the existence of
such trusts or other arrangements is consistent with the unfunded status of the Plan. 
 12. Nonexclusivity of the Plan 

The adoption of the Plan by the Board shall not be construed as creating any limitations on the power of the Board to adopt such other
incentive arrangements as it may deem desirable, including without limitation, the granting of awards other than under the Plan, and such arrangements may be either applicable generally or only in specific cases. 

13. Termination and Amendment of the Plan 
 The Board may at any time terminate the Plan or make such modifications of the Plan as it shall deem advisable. Unless the Board otherwise expressly provides, no amendment of the Plan shall affect the
terms of any Award outstanding on the date of such amendment. In any case, no termination or amendment of the Plan may, without the consent of any recipient of an Award granted hereunder, adversely affect the rights of the recipient under such
Award. 
 The Committee may amend the terms of any Award theretofore granted, prospectively or retroactively, provided that the
Award as amended is consistent with the terms of the Plan, but no such amendment shall impair the rights of the recipient of such Award without his or her consent. 

  
 8 

 14. Notices and Other Communications 

Any notice, demand, request or other communication hereunder to any party shall be deemed to be sufficient if contained in a written
instrument delivered in person or duly sent by first class registered, certified or overnight mail, postage prepaid, or telecopied with a confirmation copy by regular, certified or overnight mail, addressed or telecopied, as the case may be,
(i) if to the recipient of an Award, at his or her residence address last filed with the Company and (ii) if to the Company, at its principal place of business, addressed to the attention of its Chief Financial Officer, or to such other
address or telecopier number or electronic mail address, as the case may be, as the addressee may have designated by notice to the addressor. All such notices, requests, demands and other communications shall be deemed to have been received:
(i) in the case of personal delivery, on the date of such delivery; (ii) in the case of mailing, when received by the addressee; (iii) in the case of facsimile transmission, when confirmed by facsimile machine report; and (iv) in
the case of electronic mail, when directed to an electronic mail address at which the receiving party has consented to receive notice, provided, that such consent is deemed revoked if the sender is unable to deliver by electronic transmission
two consecutive notices and such inability becomes known to the secretary or assistant secretary of the Company or to the transfer agent, or other person responsible for giving notice. 
 15. Governing Law 
 The Plan and all Award Agreements and actions taken
thereunder shall be governed, interpreted and enforced in accordance with California law, without regard to the conflicts of laws principles of such state.

 OPTICHRON, INC. 

2011 RETENTION RSU PLAN 
 RESTRICTED STOCK UNIT AGREEMENT 
 Pursuant to the Notice of Restricted Stock Unit Award (the “Notice”) and this Restricted Stock Unit Agreement, Optichron, Inc. (the “Company”) has awarded to you
(“you” or the “Participant”) a Restricted Stock Unit Award (the “Award”) under its 2011 Restricted Stock Unit Plan (the “Plan”). The Award is granted to you effective as of the
Grant Date set forth in the Notice for this Award. This Restricted Stock Unit Agreement shall be deemed to be agreed to by the Company and you upon the signing by you of the Notice to which it is attached. Capitalized terms not explicitly defined in
this Restricted Stock Unit Agreement shall have the same meanings given to them in the Plan or the Notice, as applicable. Except as otherwise explicitly provided herein, in the event of any conflict between the terms in this Restricted Stock Unit
Agreement and the Plan, the terms of the Plan shall control. The details of your Award, in addition to those set forth in the Notice and the Plan, are as follows. 
 1. Vesting 
 No portion of the shares of Common Stock that the Participant
is entitled to receive will be issued until such portion has vested. The RSUs shall vest as provided in the Notice, provided in each case that the Participant is then, and since the Grant Date has remained, in Continuous Employment (as defined
in the Plan). 
 2. Issuance of Common Stock 
 (a) Each vested RSU entitles the Participant to receive one share of Common Stock. 

(b) The Company will deliver to, or direct its transfer agent to register in the name of the Participant a number of shares of Common
Stock equal to the number of vested RSUs subject to the Award, including any additional RSUs received pursuant to Section 5 below that relate to those vested RSUs on the applicable vesting date(s), subject to satisfactory determination by the
Company of compliance with all requirements under applicable laws or regulations in connection with such issuance of shares of Common Stock and with the requirements of this Agreement and the Plan, and subject to the provisions of Section 7 of
this Agreement. Delivery of the shares pursuant to the provisions of this Section 2(b) is intended to comply with the requirements for the short-term deferral exemption available under Treasury Regulations Section 1.409A-1(b)(4) and shall
be construed and administered in such manner. The form of such delivery of the shares (e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the Company. 

(c) Until such time as shares of Common Stock have been issued to the Participant pursuant to Section 2(b) above, the Participant
shall not have any rights as a holder of shares of Common Stock underlying the RSUs, including, but not limited to, voting rights, rights to receive dividends and other distributions with respect to Common Stock, and stockholder inspection rights.

 3. Termination of Continuous Employment 
 The Participant’s right in any RSUs that are not vested as of the date on which the Participant’s Continuous Employment has ceased shall automatically terminate on such date, and such RSUs shall
be canceled as provided under the Plan and shall be of no further force and effect. In the event of termination of Continuous Employment, the Company, as soon as practicable following the effective date of termination, shall issue shares of
Common Stock to the Participant (or the Participant’s designated beneficiary or estate executor in the event of Participant’s death) with respect to any RSUs which, as of the effective date of termination of Continuous Employment, have
vested but for which shares of Common Stock had not yet been issued to the Participant.

 4. Adjustments 

If, from time to time during the term of this Agreement and to the extent provided under Section 7.1 of the Plan: (i) there is
any stock dividend, distribution or dividend of cash or property, stock split, reverse stock split, or other change in the character or amount of any of the outstanding securities of the Company; or (ii) there is any consolidation, merger or
sale of all, or substantially all, of the assets of the Company; then in such event, any and all new, substituted or additional securities, cash or other property that Participant receives or to which the Participant is entitled by reason of the
Participant’s ownership of the RSUs shall be immediately subject to the provisions of Section 1 and be deemed subject to the RSUs for all purposes with the same force and effect as the shares of Common Stock presently subject to this
Agreement. 
 Subject to the terms of any other written agreement between the Participant and the Company related to the
Participant’s employment by or other association with the Company and in accordance with Sections 7.1, 7.2, 7.3 and 7.4 of the Plan, the Committee may, if it so determines in the exercise of its sole discretion, also make provision for
proportionately adjusting the number or class of securities covered by the RSUs, as well as the price to be paid therefor, in the event that the Company effects one or more Acquisitions, corporate separations, reorganizations, liquidations or other
increases or reductions of shares of its outstanding Common Stock. 
 5. Incorporation of General Terms and Conditions

 Notwithstanding anything herein to the contrary, this Award shall be subject to and governed by all the terms and
conditions of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified in this Agreement. 
 6. Transferability 
 This Agreement is personal to the Participant, is
non-assignable, and is not transferable in any manner, by operation of law, or otherwise, other than by will or the laws of descent and distribution. This Award is available, during the Participant’s lifetime, only to the Participant, and
thereafter, only to the Participant’s designated beneficiary. 
 7. Tax Withholding 

The Participant shall not later than the date as of which the Award becomes a taxable event for Federal income tax purposes, pay to the
Company or make arrangements satisfactory to the Company for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event. The Participant may elect to have the minimum tax withholding
obligation satisfied, in whole or in part, by (i) authorizing the Company to withhold from shares of Common Stock to be issued, or (ii) authorizing the Company to deduct cash payments from the Participant’s regularly scheduled payroll
distributions that would satisfy the minimum required tax withholding amount due. 
 8. Tax Consequences 

The Company makes no representation or warranty as to the tax treatment to the Participant of the Participant’s receipt of the Award
or vesting of RSUs or upon Participant’s sale or other disposition of the Common Stock issued pursuant to the RSUs. The Participant should rely on his or her own tax advisors for all such advice. 

9. Miscellaneous 
 (a) Notice under this Agreement shall be given to the Company at its principal place of business, and shall be given to the Participant at the address set forth below, or in either case at such other
address as one party may subsequently furnish to the other party in writing.

 (b) This Agreement does not confer upon the Participant any rights with respect to
continuation of employment by the Company or any of its subsidiaries. 
 (c) The Committee may amend the terms of this
Agreement, prospectively or retroactively, provided that the Agreement as amended is consistent with the terms of the Plan, but no such amendment shall impair the Participant’s rights under this Agreement without the Participant’s consent.

 (d) This Agreement shall be construed and enforced in accordance with the laws of California, without regard to the conflicts
of laws principles thereof. 
 (e) This Agreement shall be binding upon and inure to the benefit of any successor or assign of
the Company and any executor, administrator, trustee, guardian or other legal representative of the Participant. 
 (f) This
Agreement may be executed in counterparts. This Agreement and the Plan together constitute the entire agreement between the parties relative to the subject matter of this Agreement, and supersede all communications, whether written or oral,
relating to the subject matter of this Agreement. 
 THIS AGREEMENT is binding upon the parties and entered into effective as of
the date set forth in this Agreement. 
 CONSENT OF SPOUSE/DOMESTIC PARTNER 

I, the Participant, hereby agree that my spouse’s/domestic partner’s interest in the shares of Common Stock subject to this
Agreement shall be irrevocably bound by this Agreement’s terms. I further agree that all community property interests of mine and my spouse’s or domestic partner’s in such shares, if any, shall similarly be bound by this
Agreement and that such consent is binding upon our executors, administrators, heirs and assigns. I represent and warrant to the Company that I have the authority to bind my spouse/domestic partner with respect to the RSUs. I agree to
execute and deliver such documents as may be necessary to carry out the intent of this Agreement and this consent.
