 Exhibit 4.3 

CYPHORT INC. 

AMENDED & RESTATED 2011 STOCK INCENTIVE PLAN 

SECTION 1. INTRODUCTION. 
 The
Company’s Board of Directors initially adopted the Cyphort Inc. 2011 Stock Incentive Plan, effective as of the Adoption Date, and it was approved by the Company’s stockholders on March 1, 2011. Awards granted under the Plan prior to
the Stockholder Approval Date may not be exercised or Shares released to any Participant until such stockholder approval is obtained. 
 This
Cyphort Inc. Amended & Restated 2011 Stock Incentive Plan is to become effective as of immediately prior to the closing of the merger of Cobra Merger Co. (“Sub”) with and into the Company (the “Merger”) as
contemplated by that certain Agreement and Plan of Merger, dated August 31, 2017, by and among the Company, Juniper Networks, Inc., Sub and certain other named parties. If the Merger does not occur, this amendment and restatement of the Plan
shall have no effect, regardless of any approval thereof that may be provided by the Company’s Board of Directors or stockholders, and the prior version of the Plan shall continue in effect. 

The purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by offering Key Employees an
opportunity to acquire a proprietary interest in the success of the Company, or to increase such interest, and to encourage such Key Employees to continue to provide services to the Company and to attract new individuals with outstanding
qualifications. 
 The Plan seeks to achieve this purpose by providing for Awards in the form of Options (which may constitute Incentive
Stock Options or Nonstatutory Stock Options), Restricted Stock Grants and Restricted Stock Units. 
 Capitalized terms shall have the meaning
provided in Section 2 unless otherwise provided in this Plan or any related Stock Option Agreement or Restricted Stock Grant Agreement.

necessary or desirable to comply with provisions of the laws or regulations of other countries or jurisdictions to ensure the viability of the benefits from Awards granted to Participants employed in such countries or jurisdictions, or to meet the
requirements that permit the Plan to operate in a qualified or tax efficient manner, and/or comply with applicable foreign laws or regulations. 

The Committee may adopt such rules or guidelines, as it deems appropriate to implement the Plan. The Committee’s determinations under the
Plan shall be final, conclusive and binding on all persons. The Committee’s decisions and determinations need not be uniform and may be made selectively among Participants in the Committee’s sole discretion. The Committee’s decisions
and determinations will be afforded the maximum deference provided by applicable law.

or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or any Award agreement, and (ii) from any and all amounts paid by him or her in settlement
thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to

the Company’s Certificate of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any power that the Company may have to indemnify them or hold them harmless. 

SECTION 4. GENERAL. 
 (a)
Eligibility. Only Employees, Directors, Non-Employee Directors and Consultants shall be eligible for designation as Key Employees by the Committee. 







 (b) Incentive Stock Options. Only Key Employees who are common-law employees of the
Company, a Parent or a Subsidiary shall be eligible for the grant of ISOs. In addition, a Key Employee who is a 10-Percent Stockholder shall not be eligible for the grant of an ISO unless the requirements set forth in section 422(c)(5) of the Code
are satisfied. If and to the extent that any Shares are issued under a portion of any Option that exceeds the $100,000 limitation of section 422 of the Code, such Shares shall not be treated as issued under an ISO notwithstanding any designation
otherwise. Certain decisions, amendments, interpretations and actions by the Committee and certain actions by a Participant may cause an Option to cease to qualify as an ISO pursuant to the Code and by accepting an Option the Participant agrees in
advance to such disqualifying action taken by either the Participant, the Committee or the Company. 
 (c) Restrictions on Shares. Any
Shares issued pursuant to an Award shall be subject to such Company policies, rights of repurchase, rights of first refusal and other transfer restrictions as the Committee may determine. Such restrictions shall apply in addition to any restrictions
that may apply to holders of Shares generally and shall also comply to the extent necessary with applicable law. In no event shall the Company be required to issue fractional Shares under this Plan. 

(d) Beneficiaries. A Participant may designate one or more beneficiaries with respect to an Award by timely filing the prescribed form
with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Participant’s death. If no beneficiary was designated or if no designated beneficiary survives the Participant,
then after a Participant’s death any vested Award(s) shall be transferred or distributed to the Participant’s estate. 
 (e)
Performance Conditions. The Committee may, in its discretion, include performance conditions in any Award. 
 (f) Stockholder
Rights. A Participant, or a transferee of a Participant, shall have no rights as a stockholder (including without limitation voting rights or dividend or distribution rights) with respect to any Common Stock covered by an Award until such person
becomes entitled to receive such Common Stock, has satisfied any applicable withholding or tax obligations relating to the Award and the Common Stock has been issued to the Participant. No adjustment shall be made for cash or stock dividends or
other rights for which the record date is prior to the date when such Common Stock is issued, except as expressly provided in Section 10. The issuance of an Award shall be subject to and conditioned upon the Participant’s agreement to
become a party to a Stockholders Agreement and be bound by its terms. 
 (g) Buyout of Awards. The Committee may at any time offer to
buy out, for a payment in cash or cash equivalents (including without limitation Shares issued at Fair Market Value that may or may not be issued under this Plan), an Award previously granted based upon such terms and conditions as the Committee
shall establish. 
 (h) Termination of Service. Unless the applicable Award agreement or employment agreement provides otherwise (and
in such case, the Award or employment agreement shall govern as to the consequences of a termination of Service for such Awards subject to Section 4(i)), the following rules shall govern the vesting, exercisability and term of outstanding
Awards held by a Participant in the event of termination of such Participant’s Service (in all cases subject to the term of the Option as applicable): 







 (i) if the Service of a Participant is terminated for Cause, then all Options and unvested
portions of Restricted Stock Grants shall terminate and be forfeited immediately without consideration as of the Termination Date (except for repayment of any amounts the Participant had paid to the Company to acquire unvested Shares underlying the
forfeited Awards); 
 (ii) if the Service of Participant is terminated due to the Participant’s death or Disability, then the vested
portion of his/her then-outstanding Options may be exercised by such Participant or his or her personal representative within six months after the Termination Date and all unvested portions of any outstanding Awards shall be forfeited without
consideration as of the Termination Date (except for repayment of any amounts the Participant had paid to the Company to acquire unvested Shares underlying the forfeited Awards); and 

(iii) if the Service of Participant is terminated for any reason other than for Cause or other than due to death or Disability, then the vested
portion of his/her then-outstanding Options may be exercised by such Participant within three months after the Termination Date and all unvested portions of any outstanding Awards shall be forfeited without consideration as of the Termination Date
(except for repayment of any amounts the Participant had paid to the Company to acquire Shares underlying the forfeited Awards). 
 (i)
California Participants. Awards to California Participants shall also be subject to the following terms regarding the time period to exercise vested Options after termination of Service. These additional terms shall apply until such time that
the Shares are publicly traded and/or the Company is subject to the reporting requirements of the Exchange Act: In the event of termination of a Participant’s Service, (i) if such termination was for reasons other than death or Disability
or Cause, the Participant shall have at least 30 days after the date of such termination to exercise any of his/her vested outstanding Options (but in no event later than the expiration of the term of such Options established by the Committee as of
the Award date) or (ii) if such termination was due to death or Disability, the Participant shall have at least six months after the date of such termination to exercise any of his/her vested outstanding Options (but in no event later than the
expiration of the term of such Options established by the Committee as of the Award date). 
 (j) Suspension or Termination of Awards.
If at any time (including after a notice of exercise has been delivered) the Committee (or the Board), reasonably believes that a Participant has committed an act of Cause (which includes a failure to act), the Committee (or Board) may suspend the
Participant’s right to exercise any Option (or vesting of Restricted Stock Grants) pending a determination of whether there was in fact an act of Cause. If the Committee (or the Board) determines a Participant has committed an act of Cause,
neither the Participant nor his or her estate shall be entitled to exercise any outstanding Option whatsoever and all of Participant’s outstanding Awards shall then terminate without consideration. Any determination by the Committee (or the
Board) with respect to the foregoing shall be final, conclusive and binding on all interested parties. 







 (k) Code Section 409A. Notwithstanding anything in the Plan to the contrary, the Plan
and Awards granted hereunder are intended to comply with the requirements of Code Section 409A and shall be interpreted in a manner consistent with such intention. In the event that any provision of the Plan or an Award agreement is determined
by the Committee to not comply with the applicable requirements of Code Section 409A or the Treasury Regulations or other guidance issued thereunder, the Committee shall have the authority to take such actions and to make such changes to the
Plan or an Award Agreement as the Committee deems necessary to comply with such requirements. Each payment to a Participant made pursuant to this Plan shall be considered a separate payment and not one of a series of payments for purposes of Code
Section 409A. Notwithstanding the foregoing or anything elsewhere in the Plan or an Award Agreement to the contrary, if upon a Participant’s Separation From Service he/she is then a “specified employee” (as defined in Code
Section 409A), then solely to the extent necessary to comply with Code Section 409A and avoid the imposition of taxes under Code Section 409A, the Company shall defer payment of “nonqualified deferred compensation” subject
to Code Section 409A payable as a result of and within six (6) months following such Separation From Service under this Plan until the earlier of (i) the first business day of the seventh month following the Participant’s
Separation From Service, or (ii) ten (10) days after the Company receives written confirmation of the Participant’s death. Any such delayed payments shall be made without interest. 

(l) Electronic Communications. Subject to compliance with applicable law and/or regulations, an Award agreement or other documentation
or notices relating to the Plan and/or Awards may be communicated to Participants by electronic media, including by electronic mail. 
 (m)
Unfunded Plan. Insofar as it provides for Awards, the Plan shall be unfunded. Although bookkeeping accounts may be established with respect to Participants who are granted Awards under this Plan, any such accounts will be used merely as a
bookkeeping convenience. The Company shall not be required to segregate any assets which may at any time be represented by Awards, nor shall this Plan be construed as providing for such segregation, nor shall the Company or the Committee be deemed
to be a trustee of stock or cash to be awarded under the Plan. 
 (n) Liability of Company Plan. The Company (or members of the Board
or Committee) shall not be liable to a Participant or other persons as to: (i) the non-issuance or sale of Shares as to which the Company has been unable to obtain from any regulatory body having jurisdiction the authority deemed by the
Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder; and (ii) any unexpected or adverse tax consequence or any tax consequence expected, but not realized, by any 

Participant or other person due to the grant, receipt, exercise or settlement of any Award granted under this Plan. 







 (o) Reformation. In the event any provision of this Plan shall be held illegal or invalid
for any reason, such provisions will be reformed by the Board if possible and to the extent needed in order to be held legal and valid. If it is not possible to reform the illegal or invalid provisions then the illegality or invalidity shall not
affect the remaining parts of this Plan, and this Plan shall be construed and enforced as if the illegal or invalid provision had not been included. 

(p) Successor Provision. Any reference to a statute, rule or regulation, or to a section of a statute, rule or regulation, is a
reference to that statute, rule, regulation, or section as amended from time to time, both before and after the Adoption Date and including any successor provisions. 

(q) Governing Law. This Plan and all Awards shall be construed in accordance with and governed by the laws of the State of Delaware, but
without regard to its conflict of law provisions. The Committee may provide that any dispute as to any Award shall be presented and determined in such forum as the Committee may specify, including through binding arbitration. Unless otherwise
provided in the Award Agreement, recipients of an Award under the Plan are deemed to submit to the exclusive jurisdiction and venue of the federal or state courts of Delaware to resolve any and all issues that may arise out of or relate to the Plan
or any related Award Agreement. 
 SECTION 5. SHARES SUBJECT TO PLAN AND SHARE LIMITS. 

(a) Basic Limitations. There are 9,449,012 shares of Common Stock available for issuance under the Plan (“Share
Limit”). Of this total, 9,449,012 shares of Common Stock are available for issuance pursuant to ISOs (the “ISO Limit”). 

(b) Share Utilization. If Awards are forfeited or are terminated for any reason other than being exercised, then the Shares underlying
such forfeited Awards shall not be counted against the Share Limit. If a Participant pays the Exercise Price by Net Exercise or by surrendering previously owned Shares (or by stock attestation) and/or, as permitted by the Committee, pays any
withholding tax obligation with respect to an Award by Net Exercise or by electing to have Shares withheld or surrendering previously owned Shares (or by stock attestation), the surrendered Shares and the Shares withheld to pay taxes shall not count
toward the Share Limit. Any Shares that are delivered and any Awards that are granted by, or become obligations of, the Company, as a result of the assumption by the Company of, or in substitution for, outstanding awards previously granted by
another entity (as provided in Sections 6(e) or 8(e)) shall not be counted against the Share Limit or ISO Limit. 
 (c) Dividend
Equivalents. Any dividend equivalents distributed under the Plan shall not be counted against the Share Limit. 







 SECTION 6. TERMS AND CONDITIONS OF OPTIONS. 

(a) Stock Option Agreement. Each Award of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee
and the Company. Such Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions that are not inconsistent with the Plan (including without limitation any performance conditions).
The provisions of the various Stock Option Agreements entered into under the Plan need not be identical. The Stock Option Agreement shall also specify whether the Option is an ISO and if not specified then the Option shall be an NSO. 

(b) Number of Shares. Each Stock Option Agreement shall specify the number of Shares that are subject to the Option and shall provide
for the adjustment of such number in accordance with Section 10. 
 (c) Exercise Price. An Option’s Exercise Price shall be
established by the Committee and set forth in a Stock Option Agreement. Except with respect to outstanding stock options being assumed or Options being granted in exchange for cancellation of options granted by another issuer as provided under
Section 6(e), the Exercise Price of an Option shall not be less than 100% of the Fair Market Value (110% for 10-Percent Stockholders in the case of ISOs) of a Share on the date of Award. 

(d) Exercisability and Term. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become
vested and/or exercisable. The Stock Option Agreement shall also specify the term of the Option; provided, however that the term of an Option shall in no event exceed ten (10) years from the date of Award. An ISO that is granted to a 10-Percent
Stockholder shall have a maximum term of five (5) years. No Option can be exercised after the expiration date specified in the applicable Stock Option Agreement. A Stock Option Agreement may provide for accelerated exercisability in the event
of the Optionee’s death, Disability or retirement or other events. A Stock Option Agreement may permit an Optionee to exercise an Option before it is vested (an “early exercise”), subject to the Company’s right of repurchase at
the original Exercise Price of any Shares acquired under the unvested portion of the Option which right of repurchase shall lapse at the same rate the Option would have vested had there been no early exercise. In no event shall the Company be
required to issue fractional Shares upon the exercise of an Option and the Committee may specify a minimum number of Shares that must be purchased in any one Option exercise. 

(e) Modifications or Assumption of Options. Within the limitations of the Plan, the Committee may modify, extend or assume outstanding
Options or may accept the cancellation of outstanding stock options (whether granted by the Company or by another issuer) in return for the grant of new Options for the same or a different number of Shares and at the same or a different Exercise
Price. For the avoidance of doubt, the Committee may in its discretion Re-Price outstanding Options. No modification of an Option shall, without the consent of the Optionee, impair his or her rights or increase his or her obligations under such
Option. 







 (f) Assignment or Transfer of Options. Except as otherwise provided in the applicable
Stock Option Agreement and then only to the extent permitted by applicable law, no Option shall be transferable by the Optionee other than by will or by the laws of descent and distribution. Except as otherwise provided in the applicable Stock
Option Agreement, an Option may be exercised during the lifetime of the Optionee only by Optionee or by the guardian or legal representative of the Optionee. No Option or interest therein may be assigned, pledged or hypothecated by the Optionee
during his/her lifetime, whether by operation of law or otherwise, or be made subject to execution, attachment or similar process. 
 SECTION 7. PAYMENT
FOR OPTION SHARES. 
 (a) General Rule. The entire Exercise Price of Shares issued upon exercise of Options shall be payable in
cash (or check) at the time when such Shares are purchased by the Optionee, except as follows and if so provided for in an applicable Stock Option Agreement: 

(i) In the case of an ISO granted under the Plan, payment shall be made only pursuant to the express provisions of the applicable Stock Option
Agreement. The Stock Option Agreement may specify that payment may be made in any form(s) described in this Section 7. 
 (ii) In the
case of an NSO granted under the Plan, the Committee may in its discretion, at any time accept payment in any form(s) described in this Section 7. 

(b) Surrender of Stock. To the extent that the Committee makes this Section 7(b) applicable to an Option in a Stock Option
Agreement, payment for all or any part of the Exercise Price may be made with Shares which have already been owned by the Optionee for such duration as shall be specified by the Committee. Such Shares shall be valued at their Fair Market Value on
the date when the new Shares are purchased under the Plan. 
 (c) Cashless Exercise. To the extent that the Committee makes this
Section 7(c) applicable to an Option in a Stock Option Agreement, payment for all or a part of the Exercise Price may be made through Cashless Exercise. 

(d) Net Exercise. To the extent that the Committee makes this Section 7(d) applicable to an Option in a Stock Option Agreement,
payment for all or a part of the Exercise Price may be made through Net Exercise. 
 (e) Other Forms of Payment. To the extent that
the Committee makes this Section 7(e) applicable to an Option in a Stock Option Agreement, payment may be made in any other form that is consistent with applicable laws, regulations and rules and approved by the Committee. 







 SECTION 8. TERMS AND CONDITIONS FOR RESTRICTED STOCK GRANTS. 

(a) Restricted Stock Grant Agreement. Each Restricted Stock Grant awarded under the Plan shall be evidenced by a Restricted Stock Grant
Agreement between the Participant and the Company. Each Restricted Stock Grant shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions that are not inconsistent with the Plan
(including without limitation any performance conditions). The provisions of the Restricted Stock Grant Agreements entered into under the Plan need not be identical. 

(b) Number of Shares and Payment. Each Restricted Stock Grant Agreement shall specify the number of Shares to which the Restricted Stock
Grant pertains and is subject to adjustment of such number in accordance with Section 10. Restricted Stock Grants may be issued with or without cash consideration under the Plan. 

(c) Vesting Conditions. Each Restricted Stock Grant may or may not be subject to vesting. Vesting shall occur, in full or in
installments, upon satisfaction of the conditions specified in the Restricted Stock Grant Agreement. A Restricted Stock Grant Agreement may provide for accelerated vesting in the event of the Participant’s death, or Disability or other events.

 (d) Voting and Dividend Rights. The holder of a Restricted Stock Grant (irrespective of whether the Shares subject to the
Restricted Stock Grant are vested or unvested) awarded under the Plan shall have the same voting, dividend and other rights as the Company’s other stockholders. However, any dividends received on Shares that are unvested (whether such dividends
are in the form of cash or Shares) may be subject to the same vesting conditions and restrictions as the Restricted Stock Grant with respect to which the dividends were paid. Such additional Shares issued as dividends that are subject to the
Restricted Stock Grant shall not reduce the number of Shares available for issuance under Section 5. 
 (e) Modification or Assumption of
Restricted Stock Grants. Within the limitations of the Plan, the Committee may modify or assume outstanding Restricted Stock Grants or may accept the cancellation of outstanding Restricted Stock Grants (including stock granted by another issuer)
in return for the grant of new Restricted Stock Grants for the same or a different number of Shares. No modification of a Restricted Stock Grant shall, without the consent of the Participant, impair his or her rights or increase his or her
obligations under such Restricted Stock Grant. 
 (f) Assignment or Transfer of Restricted Stock Grants. Except as provided in
Section 13, or in a Restricted Stock Grant Agreement, or as required by applicable law, a Restricted Stock Grant awarded under the Plan shall not be anticipated, assigned, attached, garnished, optioned, transferred or made subject to any
creditor’s process, whether voluntarily, involuntarily or by operation of law. Any act in violation of this Section 8(f) shall be void. However, this Section 8(f) shall not preclude a Participant from designating a beneficiary
pursuant to Section 4(d) nor shall it preclude a transfer of Restricted Stock Grant Awards by will or pursuant to Section 4(d). 







 SECTION 9. TERMS AND CONDITIONS FOR RESTRICTED STOCK UNITS 

(a) Grant of Restricted Stock Units. Restricted Stock Units may be granted at any time and from time to time as determined by the
Committee. After the Committee determines that it will grant Restricted Stock Units under the Plan, it shall advise the Participant in writing or electronically of the terms, conditions, and restrictions related to the grant, including the number of
Restricted Stock Units and the form of payout, which may be left to the discretion of the Committee. Until the Shares are issued, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Restricted
Stock Units to acquire Shares. 
 (b) Vesting Criteria and Other Terms. The Committee shall set vesting criteria in its discretion,
which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Committee may set vesting criteria based upon the achievement of Company-wide, business
unit, or individual goals (including, but not limited to, continued employment), or any other basis determined by the Administrator in its discretion. 

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant shall be entitled to receive a payout
as specified in his or her Restricted Stock Unit Award Agreement. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Committee, in its sole discretion, may reduce or waive any vesting criteria that must be met
to receive a payout. 
 (d) Timing. Payment of earned Restricted Stock Units shall be made as soon as practicable after the date(s)
set forth in the Restricted Stock Unit Award Agreement. 
 (e) Form. The Committee, in its sole discretion, but only as specified in
the Restricted Stock Unit Award Agreement, may pay earned Restricted Stock Units in cash, Shares, or a combination thereof. If a Restricted Stock Unit Award Agreement is silent as to the form of payment, payment of the Restricted Stock Units may
only be in Shares; provided that any fractional share may be paid in cash. 
 (f) Cancellation. Any Restricted Stock Units that do not
vest pursuant to the terms and conditions set forth in a Participant’s Restricted Stock Unit Agreement shall immediately revert to the Plan. 

(g) Compliance with Code Section 409A. Notwithstanding anything in this Section 9 to the contrary, all Restricted Stock Unit
Awards are intended to be structured to satisfy the requirements of Code Section 409A, or an applicable exemption, as determined by the Committee. 

SECTION 10. ADJUSTMENTS. 
 (a)
Adjustments. In the event of a subdivision of the outstanding Shares, a declaration of a dividend payable in Shares, a declaration of a dividend payable in a form other than Shares in an amount that has a material effect on the price of
Shares, a combination or consolidation of the outstanding Shares (by reclassification or otherwise) 







 
into a lesser number of Shares, a stock split, a reverse stock split, a reclassification or other distribution of the Shares without the receipt of consideration by the Company, of or on the
Common Stock, a recapitalization, a combination, a spin-off or a similar occurrence, the Committee shall make equitable and proportionate adjustments to: 

(i) the Share Limit and ISO Limit specified in Section 5(a); 

(ii) the number and kind of securities available for Awards (and which can be issued as ISOs) under Section 5; 

(iii) the number and kind of securities covered by each outstanding Award; 

(iv) the Exercise Price under each outstanding Option; and 

(v) the number and kind of outstanding securities issued under the Plan. 

(b) Participant Rights. Except as provided in this Section 10, a Participant shall have no rights by reason of any issue by the
Company of stock of any class or securities convertible into stock of any class, any subdivision or consolidation of shares of stock of any class, the payment of any stock dividend or any other increase or decrease in the number of shares of stock
of any class. If by reason of an adjustment pursuant to this Section 10, a Participant’s Award covers additional or different shares of stock or securities, then such additional or different shares and the Award in respect thereof shall be
subject to all of the terms, conditions and restrictions which were applicable to the Award and the Shares subject to the Award prior to such adjustment. 

(c) Fractional Shares. Any adjustment of Shares pursuant to this Section 10 shall be rounded down to the nearest whole number of
Shares. Under no circumstances shall the Company be required to authorize or issue fractional shares. To the extent permitted by applicable law, no consideration shall be provided as a result of any fractional shares not being issued or authorized.

 SECTION 11. EFFECT OF A CHANGE IN CONTROL. 

(a) Merger or Reorganization. In the event that there is a Change in Control and/or the Company is a party to a merger or acquisition or
reorganization or similar transaction, outstanding Awards shall be subject to the merger agreement or other applicable transaction agreement. Such agreement may provide, without limitation, that subject to the consummation of the applicable
transaction, for the assumption (or substitution) of outstanding Awards by the surviving corporation or its parent, for their continuation by the Company (if the Company is a surviving corporation), for accelerated vesting or for their cancellation
with or without consideration, in all cases without the consent of the Participant. For the avoidance of any doubt, outstanding Restricted Stock Units shall terminate and be cancelled for no consideration upon consummation of a Change in Control
except to the extent that the Restricted Stock Units are assumed by the successor entity (or parent or subsidiary thereof) pursuant to the terms of the agreement governing the Change in Control transaction. 







 (b) Acceleration of Vesting. In the event that a Change in Control occurs and there is no
assumption, substitution or continuation of Awards pursuant to Section 11(a), the Committee in its discretion may provide that all Awards shall vest and become exercisable as of immediately before such Change in Control. For avoidance of doubt,
“substitution” includes, without limitation, an Award being replaced by a cash award that provides an equivalent intrinsic value (wherein intrinsic value equals the difference between the market value of a share and any exercise price).
The Committee may also in its discretion include in an Award agreement a requirement that unless Section 280G Approval has been obtained, no acceleration of vesting shall occur with respect to an Award to the extent that such acceleration
would, after taking into account any other payments in the nature of compensation to which the Participant would have a right to receive from the Company and any other person contingent upon the occurrence of such Change in Control, result in a
“parachute payment” as defined under Code Section 280G. 
 SECTION 12. LIMITATIONS ON RIGHTS. 

(a) Retention Rights. Neither the Plan nor any Award granted under the Plan shall be deemed to give any individual a right to remain in
Service as an Employee, Consultant, Director or Non-Employee Director of the Company, a Parent, a Subsidiary or an Affiliate or to receive any future Awards under the Plan. The Company and its Parents and Subsidiaries and Affiliates reserve the
right to terminate the Service of any person at any time, and for any reason, subject to applicable laws, the Company’s Certificate of Incorporation and Bylaws and a written employment agreement (if any). 

(b) Regulatory Requirements. Any other provision of the Plan notwithstanding, the obligation of the Company to issue Shares or other
securities under the Plan shall be subject to all applicable laws, rules and regulations and such approval by any regulatory body as may be required. The Company reserves the right to restrict, in whole or in part, the delivery of Shares or other
securities pursuant to any Award prior to the satisfaction of all legal requirements relating to the issuance of such Shares or other securities, to their registration, qualification or listing or to an exemption from registration, qualification or
listing 
 (c) Dissolution. To the extent not previously exercised or settled, all Options and unvested Restricted Stock Grants shall
terminate immediately prior to the dissolution or liquidation of the Company and shall be forfeited to the Company without consideration. 

(d) Clawback Policy. The Company may (i) cause the cancellation of any Award, (ii) require reimbursement of any Award by a
Participant and (iii) effect any other right of recoupment of equity or other compensation provided under this Plan or otherwise in accordance with Company policies and/or applicable law (each, a “Clawback Policy”). In
addition, a Participant may be required to repay to the Company certain previously paid compensation, whether provided under this Plan or an Award Agreement or otherwise, in accordance with the Clawback Policy. 







 SECTION 13. WITHHOLDING TAXES. 

(a) General. A Participant shall make arrangements satisfactory to the Company for the satisfaction of any withholding tax obligations
that arise in connection with his or her Award. The Company shall not be required to issue any Shares or make any cash payment under the Plan until such obligations are satisfied. 

(b) Share Withholding. The Committee in its discretion may permit or require a Participant to satisfy all or part of his or her
withholding tax obligations by having the Company withhold all or a portion of any Shares that otherwise would be issued to him or her or by surrendering all or a portion of any Shares that he or she previously acquired (or by stock attestation).
Such Shares shall be valued based on the value of the actual trade or, if there is none, the Fair Market Value as of the previous day. Any payment of taxes by assigning Shares to the Company may be subject to restrictions, including, but not limited
to, any restrictions required by rules of the SEC. The Committee may also, in its discretion, permit or require a Participant to satisfy withholding tax obligations related to an Award through a sale of Shares underlying the Award or, in the case of
Options, through Net Exercise or Cashless Exercise. The number of Shares that are withheld from an Award pursuant to this section may also be limited by the Committee, to the extent necessary, to avoid liability-classification of the Award (or other
adverse accounting treatment) under applicable financial accounting rules. 
 SECTION 14. DURATION AND AMENDMENTS. 

(a) Term of the Plan. The Plan, as set forth herein, is effective on the Adoption Date provided, however, that the Plan is subject to
the approval of the Company’s stockholders within one year of the Adoption Date. If the Stockholder Approval Date does not occur before the first anniversary of the Adoption Date, then the Plan shall terminate as of the first anniversary of the
Adoption Date and any Awards granted under the Plan shall also immediately terminate without consideration to any Award holder. If the stockholders timely approve the Plan, then the Plan shall terminate on the day before the tenth anniversary of the
Adoption Date and may be terminated on any earlier date pursuant to this Section 14. This Plan will not in any way affect outstanding awards that were issued under any other Company equity compensation plans. 

(b) Right to Amend or Terminate the Plan. The Board may amend or terminate the Plan at any time and for any reason. No Awards shall be
granted under the Plan after the Plan’s termination. An amendment of the Plan shall be subject to the approval of the Company’s stockholders only to the extent required by applicable laws, regulations or rules. In addition, no such
amendment or termination shall be made which would impair the rights of any Participant, without such Participant’s written consent, under any then- outstanding Award, provided that no such Participant consent shall be required with respect to
any amendment or alteration if the Committee determines in its sole discretion that such amendment or alteration either (i) is required or advisable in order for the Company, the Plan or the Award to satisfy or conform to any law or regulation
or to meet 







 
the requirements of any accounting standard, or (ii) is not reasonably likely to significantly diminish the benefits provided under such Award, or that any such diminishment has been
adequately compensated. In the event of any conflict in terms between the Plan and any Award agreement, the terms of the Plan shall prevail and govern. 

SECTION 15. EXECUTION. 
 The Company has
caused its duly authorized Officer to execute this amended Plan on behalf of the Company.
