 4. Administration of the Plan. 
 (a) Administrator. The Plan shall be administered by the Board or a Committee appointed by the Board, which Committee shall be constituted to comply with Applicable Laws. 
 (b) Powers of the Administrator. Subject to the provisions of the Plan and, in the case of a Committee, the specific duties delegated
by the Board to such Committee, and subject to the approval of any relevant authorities, the Administrator shall have the authority in its discretion: 
 (i) to determine the Fair Market Value; 
 (ii) to select the Service Providers to
whom Options and Stock Purchase Rights may from time to time be granted hereunder; 
 (iii) to determine the number of Shares
to be covered by each such award granted hereunder; 
 (iv) to approve forms of agreement for use under the Plan; 

(v) to determine the terms and conditions of any Option or Stock Purchase Right granted hereunder. Such terms and conditions include,
but are not limited to, the exercise price, the time or times when Options or Stock Purchase Rights may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Option or Stock Purchase Right or the Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine; 
 (vi) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of satisfying applicable foreign laws; 
 (vii) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be issued upon exercise of an Option or Stock Purchase Right that number of Shares having a Fair Market Value equal to the

  

 4 

 
minimum amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections
by Optionees to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable; and 
 (viii) to construe and interpret the terms of the Plan and Options granted pursuant to the Plan. 
 (c) Effect of Administrator’s Decision. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Optionees. 
 5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options may
be granted only to Employees. 
 6. Limitations. 
 (a) Incentive Stock Option Limit. Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any
calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in
the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. 
 (b) At-Will Employment. Neither the Plan nor any Option or Stock Purchase Right shall confer upon any Optionee any right with respect to continuing the Optionee’s relationship as a Service
Provider with the Company, nor shall it interfere in any way with his or her right or the Company’s right to terminate such relationship at any time, with or without cause, and with or without notice. 
 7. Term of Plan. Subject to stockholder approval in accordance with Section 19, the Plan shall become effective upon its
adoption by the Board. Unless sooner terminated under Section 15, it shall continue in effect for a term of ten (10) years from the later of (i) the effective date of the Plan, or (ii) the earlier of the most recent Board or
stockholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 8. Term of Option.
The term of each Option shall be stated in the Option Agreement; provided, however, that the term shall be no more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Optionee who, at the
time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant
or such shorter term as may be provided in the Option Agreement. 
 9. Option Exercise Price and Consideration.

  

 5 

 (a) Exercise Price. The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator, but shall be subject to the following: 
 (i)
In the case of an Incentive Stock Option 
 (A) granted to an Employee who, at the time of grant of such Option, owns stock
representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. 

(B) granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the
date of grant. 
 (ii) In the case of a Nonstatutory Stock Option 
 (A) granted to a Service Provider who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. 
 (B) granted to any other Service Provider, the per Share exercise price shall be no less than 85% of the Fair Market Value per Share on the
date of grant. 
 (iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than as
required above pursuant to a merger or other corporate transaction. 
 (b) Forms of Consideration. The consideration to
be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant). Such consideration
may consist of, without limitation, (i) cash, (ii) check, (iii) promissory note, (iv) other Shares, provided Shares that were acquired directly from the Company (x) have been owned by the Optionee for more than six
(6) months on the date of surrender, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option shall be exercised, (v) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with the Plan, or (vi) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to benefit the Company. 
 10. Exercise of
Option. 
 (a) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable
according to the terms hereof at such times and under such

  

 6 

 
conditions as determined by the Administrator and set forth in the Option Agreement. An Option may not be exercised for a fraction of a Share. Except in the case of Options granted to officers,
Directors and Consultants, Options shall become exercisable at a rate of no less than 20% per year over five (5) years from the date the Options are granted. 
 An Option shall be deemed exercised when the Company receives (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option,
and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares
issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Shares, notwithstanding the exercise of the Option. The Company shall issue
(or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the
Plan. 
 Exercise of an Option in any manner shall result in a decrease in the number of Shares thereafter available for sale
under the Option, by the number of Shares as to which the Option is exercised. 
 (b) Termination of Relationship as a
Service Provider. If an Optionee ceases to be a Service Provider, such Optionee may exercise his or her Option within thirty (30) days of termination, or such longer period of time as specified in the Option Agreement, to the extent that
the Option is vested on the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Option Agreement). If, on the date of termination, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan. 
 (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within six (6) months of termination, or such longer period of time as specified in the Option Agreement, to the extent the Option is vested on
the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the
Plan. 
 (d) Death of Optionee. If an Optionee dies while a Service Provider, the Option may be exercised within six
(6) months following Optionee’s death, or such longer period of time as specified in the Option Agreement, to the extent that the Option is vested on the date of

  

 7 

 
death (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement) by the Optionee’s designated beneficiary, provided such beneficiary has been
designated prior to Optionee’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Optionee, then such Option may be exercised by the personal representative of the Optionee’s estate or by the
person(s) to whom the Option is transferred pursuant to the Optionee’s will or in accordance with the laws of descent and distribution. If, at the time of death, the Optionee is not vested as to his or her entire Option, the Shares covered by
the unvested portion of the Option shall immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 
 (e) Leaves of Absence. 
 (i) Unless the Administrator provides otherwise, vesting of Options granted hereunder to officers and Directors shall be suspended during any unpaid leave of absence. 
 (ii) A Service Provider shall not cease to be an Employee in the case of (A) any leave of absence approved by the Company or
(B) transfers between locations of the Company or between the Company, its Parent, any Subsidiary, or any successor. 
 (iii) For purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon
expiration of a leave of absence approved by the Company is not so guaranteed, then three (3) months following the 91st day of such leave, any Incentive Stock Option held by the Optionee shall cease to be treated as an Incentive Stock
Option and shall be treated for tax purposes as a Nonstatutory Stock Option. 
 11. Stock Purchase Rights. 
 (a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted
under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically of the terms, conditions and
restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such offer. The terms of the offer shall comply in all respects
with Section 260.140.42 of Title 10 of the California Code of Regulations. The offer shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator. 
 (b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the Company
a repurchase option exercisable within 90 days of the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the

  

 8 

 
Company. The repurchase option shall lapse at such rate as the Administrator may determine. Except with respect to Shares purchased by officers, Directors and Consultants, the repurchase option
shall in no case lapse at a rate of less than 20% per year over five (5) years from the date of purchase. 
 (c)
Other Provisions. The Restricted Stock Purchase Agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 (d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser shall have rights equivalent to those of a
stockholder and shall be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or other right for which the record date is prior to the
date the Stock Purchase Right is exercised, except as provided in Section 13 of the Plan. 
 12. Limited Transferability
of Options and Stock Purchase Rights. Unless determined otherwise by the Administrator, Options and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or the laws
of descent and distribution, and may be exercised during the lifetime of the Optionee, only by the Optionee. If the Administrator in its sole discretion makes an Option or Stock Purchase Right transferable, such Option or Stock Purchase Right may
only be transferred (i) by will, (ii) by the laws of descent and distribution, or (iii) to family members (within the meaning of Rule 701 of the Securities Act) through gifts or domestic relations orders, as permitted by Rule 701 of
the Securities Act. 
 13. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 
 (a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or
other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate
structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, shall adjust the number and class of Shares
that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Option or Stock Purchase Right; provided, however, that the Administrator shall make such adjustments to the extent required by
Section 25102(o) of the California Corporations Code. 
 (b) Dissolution or Liquidation. In the event of the
proposed dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Option or Stock
Purchase Right will terminate immediately prior to the consummation of such proposed action. 
  

 9 

 (c) Merger or Change in Control. In the event of a merger of the Company with or into
another corporation, or a Change in Control, each outstanding Option and Stock Purchase Right shall be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that
the successor corporation in a merger or Change in Control refuses to assume or substitute for the Option or Stock Purchase Right, then the Optionee shall fully vest in and have the right to exercise the Option or Stock Purchase Right as to all of
the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable. If an Option or Stock Purchase Right becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or Change in
Control, the Administrator shall notify the Optionee in writing or electronically that the Option or Stock Purchase Right shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option or Stock
Purchase Right shall terminate upon expiration of such period. For the purposes of this paragraph, the Option or Stock Purchase Right shall be considered assumed if, following the merger or Change in Control, the option or right confers the right to
purchase or receive, for each Share of Optioned Stock subject to the Option or Stock Purchase Right immediately prior to the merger or Change in Control, the consideration (whether stock, cash, or other securities or property) received in the merger
or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide
for the consideration to be received upon the exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock subject to the Option or Stock Purchase Right, to be solely common stock of the successor corporation or its Parent equal
in fair market value to the per share consideration received by holders of common stock in the merger or Change in Control. 
 14. Time of Granting Options and Stock Purchase Rights. The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such later date as is determined by the Administrator. Notice of the determination shall be given to each Service Provider to whom an Option or Stock Purchase Right is so granted within a reasonable time after the date of such
grant. 
 15. Amendment and Termination of the Plan. 
 (a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 
 (b) Stockholder Approval. The Board shall obtain stockholder approval of any Plan amendment to the extent necessary and desirable to
comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension or
termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company. Termination of the Plan
shall not affect the

  

 10 

 
Administrator’s ability to exercise the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of such termination. 
 16. Conditions Upon Issuance of Shares. 
 (a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option or Stock Purchase Right unless the exercise of such Option or Stock Purchase Right and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. 
 (b) Investment Representations. As a condition to the exercise of an Option or Stock Purchase Right, the Administrator may require the person exercising such Option or Stock Purchase Right to
represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation
is required. 
 17. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained. 
 18. Reservation of Shares. The Company,
during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
 19. Stockholder Approval. The Plan shall be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted. Such stockholder approval shall
be obtained in the degree and manner required under Applicable Laws. 
 20. Information to Optionees. The Company shall
provide to each Optionee and to each individual who acquires Shares pursuant to the Plan, not less frequently than annually during the period such Optionee has one or more Options or Stock Purchase Rights outstanding, and, in the case of an
individual who acquires Shares pursuant to the Plan, during the period such individual owns such Shares, copies of annual financial statements. The Company shall not be required to provide such statements to key employees whose duties in connection
with the Company assure their access to equivalent information.

 If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an
Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option
(“NSO”). 
 2. Exercise of Option. 
 (a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice
of Grant and with the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of Exercise. This Option
shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which shall state the election to exercise the Option, the number of Shares with respect to which the
Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed
to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise complies with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the
Optionee on the date on which the Option is exercised with respect to such Shares. 
 3. Optionee’s Representations.
In the event the Shares have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option,
deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B. 
 4.
Lock-Up Period. Optionee hereby agrees that Optionee shall not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or
otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap,

  

 13 

 
hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by
Optionee (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective
date of any registration statement of the Company filed under the Securities Act. 
 Optionee agrees to execute and deliver such
other agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the
underwriters of Common Stock (or other securities) of the Company, Optionee shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any
public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section shall not apply to a registration relating solely to employee benefit plans on Form S-1
or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer
instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Optionee agrees that any transferee of the Option or shares acquired
pursuant to the Option shall be bound by this Section. 
 5. Method of Payment. Payment of the aggregate Exercise Price
shall be by any of the following, or a combination thereof, at the election of the Optionee: 
 (a) cash or check; 

(b) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or

 (c) surrender of other Shares which, (i) in the case of Shares acquired from the Company, either directly or indirectly,
have been owned by the Optionee for more than six (6) months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares. 
 6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the stockholders of
the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 
 7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent
or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
  

 14 

 8. Term of Option. This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 
 9.
Tax Obligations. 
 (a) Withholding Taxes. Optionee agrees to make appropriate arrangements with the Company (or
the Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Optionee acknowledges and agrees that the
Company may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise. 
 (b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the
ISO on or before the later of (1) the date two years after the Date of Grant, or (2) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that
Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee. 
 10.
Entire Agreement; Governing Law. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all
prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee. This
agreement is governed by the internal substantive laws but not the choice of law rules of the State of California. 
 11. No
Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING
HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED
PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE
PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 Optionee acknowledges receipt of a copy of the Plan and represents that he or
she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their

  

 15 

 
entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding,
conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option. Optionee further agrees to notify the Company upon any change in the residence address indicated below.

 EXHIBIT A 
 2003 STOCK PLAN 
 EXERCISE NOTICE 
 Kazeon Systems, Inc. 
 1161 San Antonio Road

 Mountain View, CA 94043 
 Attention:
Chief Financial Officer 
 1. Exercise of Option. Effective as of today,
                    ,             , the undersigned
(“Optionee”) hereby elects to exercise Optionee’s option to purchase [                    ] shares of the Common
Stock (the “Shares”) of Kazeon Systems, Inc. (the “Company”) under and pursuant to the 2003 Stock Plan (the “Plan”) and the Stock Option Agreement dated
[                    ,              ] (the “Option
Agreement”). 
 2. Delivery of Payment. Optionee herewith delivers to the Company the full purchase price of
the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 
 3. Representations of Optionee. Optionee acknowledges that Optionee has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 
 4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a
duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued to the
Optionee as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as provided in
Section 13 of the Plan. 
 5. Company’s Right of First Refusal. Before any Shares held by Optionee or any
transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal
to purchase the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such
Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other
consideration for which the Holder proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 
  

 17 

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price
(“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (d) Payment.
Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an
assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are
not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 120 days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this
Section shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the
Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on
the Optionee’s death by will or intestacy to the Optionee’s immediate family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family” as used
herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall
be no further transfer of such Shares except in accordance with the terms of this Section. 
 (g) Termination of Right of
First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has
equity securities that are publicly traded. 
 6. Tax Consultation. Optionee understands that Optionee may suffer adverse
tax consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in

  

 18 

 
connection with the purchase or disposition of the Shares and that Optionee is not relying on the Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially equivalent thereto, to be placed upon any certificate(s) evidencing
ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER
THE ACT OR, IN THE OPINION OF COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY THE ISSUER
OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE
BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER
FOR A PERIOD NOT TO EXCEED 180 DAYS FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING
UNDERWRITER. 
 (b) Stop-Transfer Notices. Optionee agrees that, in order to ensure compliance with the restrictions
referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own
records. 
 (c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that
have been sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right

  

 19 

 
to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 
 8. Successors and Assigns. The Company may assign any of its rights under this Exercise Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors
and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon Optionee and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute regarding the interpretation of this Exercise Notice shall be submitted by Optionee or by the Company
forthwith to the Administrator which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is governed by the internal substantive laws but not the choice of law rules,
of the State of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Option Agreement will continue in full force and effect. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein by reference. This Exercise Notice, the Plan, the Option
Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee.

 INVESTMENT REPRESENTATION STATEMENT 
  

					
	 OPTIONEE:
	 	 	  	
			
	COMPANY:    	 	KAZEON SYSTEMS, INC.	  	
			
	 SECURITY:
	 	COMMON STOCK	  	
			
	 AMOUNT:

	 DATE:
	 	 	  	

 In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following: 
 (a) Optionee is aware of the Company’s business affairs and financial
condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a
view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for
the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further
understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under
no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with any legend required under applicable state securities laws. 
 (c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies
under Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of

  

 21 

 
Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under
Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly
with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during
any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable. 
 In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144,
which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of
acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately
above. 
 (d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not
satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and
Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing
that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

	II.	AGREEMENT 

 1.
Grant of Option. The Administrator of the Company hereby grants to the Optionee named in the Notice of Grant in Part I of this Agreement (the “Optionee”), an option (the “Option”) to purchase the number of
Shares set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference.
Subject to Section 15(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an
Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the S100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option
(“NSO”). 
 2. Exercise of Option. This Option shall be exercisable during its term in accordance
with the provisions of Section 10 of the Plan as follows: 
 (a) Right to Exercise. 
 (i) Subject to subsections 2(a)(ii) and 2(a)(iii) below, this Option shall be exercisable cumulatively according to the vesting schedule
set forth in the Notice of Grant. Alternatively, at the election of the Optionee, this Option may be exercised prior to April 1, 2004 in whole or in part as to Shares that have not yet vested. Following March 31, 2004, the Optionee will no
longer have the ability to exercise this Option as to unvested Shares. Vested Shares shall not be subject to the Company’s repurchase right (as set forth in the Restricted Stock Purchase Agreement, attached hereto as Exhibit C-1).

 (ii) As a condition to exercising this Option for unvested Shares prior to April 1, 2004, the Optionee shall execute
the Restricted Stock Purchase Agreement. 
 (iii) This Option may not be exercised for a fraction of a Share. 
 (b) Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A
(the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the
Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all 
  

 24 

 
Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws. Assuming
such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such Shares. 
 3. Optionee’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended, at
the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto
as Exhibit B. 
 4. Lock-Up Period. Optionee hereby agrees that Optionee shall not offer, pledge, sell, contract
to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other securities) of
the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by Optionee (other than
those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of any
registration statement of the Company filed under the Securities Act. 
 Optionee agrees to execute and deliver such other
agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the
underwriters of Common Stock (or other securities) of the Company, Optionee shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any
public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section shall not apply to a registration relating solely to employee benefit plans on Form S-1
or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer
instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Optionee agrees that any transferee of the Option or shares acquired
pursuant to the Option shall be bound by this Section. 
 5. Method of Payment. Payment of the aggregate Exercise Price
shall be by any of the following, or a combination thereof, at the election of the Optionee: 
 (a) cash; 
  

 25 

 (b) check; 
 (c) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of other Shares which, (i) in the case of Shares acquired from the Company, either directly or indirectly, have been
vested and owned by the Optionee for more than six (6) months on the date of surrender, and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares. 
 6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the shareholders of
the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 
 7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent
or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
 8. Term of Option. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such
term only in accordance with the Plan and the terms of this Option. 
 9. Tax Obligations. 
 (a) Withholding Taxes. Optionee agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or
retaining Optionee) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Optionee acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b)
Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (1) the date
two years after the Date of Grant, and (2) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax withholding by
the Company on the compensation income recognized by the Optionee. 
 10. Entire Agreement; Governing Law. The Plan is
incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and
Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and

  

 26 

 
Optionee. This Agreement is governed by the internal substantive laws but not the choice of law rules of California. 
 11. No Guarantee of Continued Service. OPTIONEE AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE
COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE
OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 Optionee acknowledges receipt of a
copy of the Plan and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their entirety,
has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option. Optionee further agrees to notify the Company upon any change in the residence address indicated below.

 2003 STOCK PLAN 
 EXERCISE NOTICE 
 Kazeon Systems, Inc. 
 1161 San Antonio Road

 Mountain View, CA 94043 
 Attention:
Chief Financial Officer 
 1. Exercise of Option. Effective as of today,
                                ,
            ,the undersigned (“Optionee”) hereby elects to exercise Optionee’s option (the “Option”) to purchase
             shares of the Common Stock (the “Shares”) of Kazeon Systems, Inc. (the “Company”) under and pursuant to the 2003 Stock Plan (the
“Plan”) and the Stock Option Agreement dated
                                ,
             (the “Option Agreement”). 
 2. Delivery of Payment. Purchaser herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection with the exercise of the Option.

 3. Representations of Optionee. Optionee acknowledges that Optionee has received, read and understood the Plan and the
Option Agreement and agrees to abide by and be bound by their terms and conditions. 
 4. Rights as Shareholder. Until
the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect
to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued to the Optionee as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or
other right for which the record date is prior to the date of issuance except as provided in Section 13 of the Plan. 
 5.
Company’s Right of First Refusal. Before any Shares held by Optionee or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift
or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the
“Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed
Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered
Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 
  

 28 

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price
(“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (d) Payment.
Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an
assignee, to the assignee), or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided
in this Section, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 120 days after the date of the Notice,
that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such
Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First
Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family
Transfers. Anything to the contrary contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s immediate
family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or
sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this
Section. 
 (g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon
the earlier of (i) first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 
 6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s purchase
or disposition of the Shares. Optionee

  

 29 

 
represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the
Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT
BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN
COMPLIANCE THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT
OF FIRST REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS
AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
TO RESTRICTIONS ON TRANSFER FOR A PERIOD NOT TO EXCEED 180 DAYS FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER WITHOUT THE CONSENT OF THE
COMPANY. 
 (b) Stop-Transfer Notices. Optionee agrees that, in order to ensure compliance with the restrictions referred
to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

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

 30 

 8. Successors and Assigns. The Company may assign any of its rights under this
Exercise Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon
Optionee and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute
regarding the interpretation of this Exercise Notice shall be submitted by Optionee or by the Company forthwith to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator
shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is governed by the
internal substantive laws, but not the choice of law rules, of California. 
 11. Entire Agreement. The Plan and Option
Agreement are incorporated herein by reference. This Exercise Notice, the Plan, the Restricted Stock Purchase Agreement, the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to
the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means
of a writing signed by the Company and Optionee.

	  	KAZEON SYSTEMS, INC.
		
	 SECURITY:
	  	COMMON STOCK
		
	 AMOUNT:
	  	_________ SHARES
		
	 DATE:
	  	___________________________

 In connection with the purchase of the above-listed Securities, the undersigned Optionee represents
to the Company the following: 
 (a) Optionee is aware of the Company’s business affairs and financial condition and has
acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a view to, or for
resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for
the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further
understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under
no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with any legend required under applicable state securities laws. 
 (c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies
under Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934,

  

 32 

 
ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain
of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during any three month period not exceeding the limitations specified in
Rule 144(e), and (4) the timely filing of a Form 144, if applicable. 
 In the event that the Company does not qualify
under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one year after the later of the date the
Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds
the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately above. 
 (d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some
other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private
placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any such other registration exemption will be available in such event.

 2003 STOCK PLAN

 RESTRICTED STOCK PURCHASE AGREEMENT 
 THIS AGREEMENT is made between
                                         
                                    (the
“Purchaser”) and Kazeon Systems, Inc. (the “Company”) or its assignees of rights hereunder as of
                                        ,
                . 
 Unless otherwise
defined herein, the terms defined in the 2003 Stock Plan shall have the same defined meanings in this Agreement. 
 RECITALS

 A. Pursuant to the exercise of the option (grant number
                ) granted to Purchaser under the Plan and pursuant to the Option Agreement dated
                        ,              by and between
the Company and Purchaser with respect to such grant (the “Option”), which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase
             of those shares of Common Stock which have not become vested under the vesting schedule set forth in the Option Agreement (“Unvested Shares”).
The Unvested Shares and the shares subject to the Option Agreement, which have become vested are sometimes collectively referred to herein as the “Shares.” 
 B. As required by the Option Agreement, as a condition to Purchaser’s election to exercise the option, Purchaser must execute this
Agreement, which sets forth the rights and obligations of the parties with respect to Shares acquired upon exercise of the Option. 
 1. Repurchase Option. 
 (a) If Purchaser’s status as a Service Provider is terminated for any reason,
including for death and Disability, the Company shall have the right and option for ninety (90) days from such date to purchase from Purchaser, or Purchaser’s personal representative, as the case may be, all of the Purchaser’s
Unvested Shares as of the date of such termination at the price paid by the Purchaser for such Shares (the “Repurchase Option”). 
 (b) Upon the occurrence of such termination, the Company may exercise its Repurchase Option by delivering personally or by registered mail, to Purchaser (or his transferee or legal representative, as the
case may be) with a copy to the escrow agent described in Section 2 below, a notice in writing indicating the Company’s intention to exercise the Repurchase Option AND, at the Company’s option, (i) by delivering to the Purchaser
(or the Purchaser’s transferee or legal representative) a check in the amount of the aggregate repurchase price, or (ii) by the Company canceling an amount of the Purchaser’s indebtedness to the Company equal to the aggregate
repurchase price, or (iii) by a combination of (i) and (ii) so that the combined payment and cancellation of indebtedness equals such aggregate repurchase price.

  

 34 

 
Upon delivery of such notice and payment of the aggregate repurchase price in any of the ways described above, the Company shall become the legal and beneficial owner of the Unvested Shares being
repurchased and the rights and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Unvested Shares being repurchased by the Company. 
 (c) Whenever the Company shall have the right to repurchase Unvested Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons or organizations to exercise all or a part of the Company’s Repurchase Option under this Agreement and purchase all or a part of such Unvested Shares. 
 (d) If the Company does not elect to exercise the Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following the termination, the Repurchase Option shall terminate. 
 (e) The Repurchase Option shall terminate in
accordance with the vesting schedule contained in Purchaser’s Option Agreement. 
 2. Transferability of the Shares;
Escrow. 
 (a) Purchaser hereby authorizes and directs the Secretary of the Company, or such other person designated by the
Company, to transfer the Unvested Shares as to which the Repurchase Option has been exercised from Purchaser to the Company. 
 (b) To insure the availability for delivery of Purchaser’s Unvested Shares upon repurchase by the Company pursuant to the Repurchase Option under Section 1, Purchaser hereby appoints the Secretary, or any other person designated
by the Company as escrow agent (the “Escrow Agent”), as its attorney-in-fact to sell, assign and transfer unto the Company, such Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall,
upon execution of this Agreement, deliver and deposit with the Escrow Agent, the share certificates representing the Unvested Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested
Shares and stock assignment shall be held by the Escrow Agent in escrow, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as Exhibit C-3 hereto, until the Company exercises its Repurchase Option, until such
Unvested Shares are vested, or until such time as this Agreement no longer is in effect. Upon vesting of the Unvested Shares, the Escrow Agent shall promptly deliver to the Purchaser the certificate or certificates representing such Shares in the
Escrow Agent’s possession belonging to the Purchaser, and the Escrow Agent shall be discharged of all further obligations hereunder; provided, however, that the Escrow Agent shall nevertheless retain such certificate or certificates as Escrow
Agent if so required pursuant to other restrictions imposed pursuant to this Agreement. 
 (c) The Company nor the Escrow Agent
shall be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment. 
  

 35 

 (d) Transfer or sale of the Shares is subject to restrictions on transfer imposed by any
applicable state and federal securities laws. Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the Purchaser with respect to any Unvested Shares purchased by Purchaser and shall
acknowledge the same by signing a copy of this Agreement. 
 3. Ownership, Voting Rights, Duties. This Agreement shall
not affect in any way the ownership, voting rights or other rights or duties of Purchaser, except as specifically provided herein. 
 4. Legends. The share certificate evidencing the Shares issued hereunder shall be endorsed with the following legend (in addition to any legend required under applicable federal and state securities laws): 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN
AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 
 5.
Adjustment for Stock Split. All references to the number of Shares and the purchase price of the Shares in this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares, which may be
made by the Company pursuant to Section 13 of the Plan after the date of this Agreement. 
 6. Notices. Notices
required hereunder shall be given in person or by registered mail to the address of Purchaser shown on the records of the Company, and to the Company at their respective principal executive offices. 
 7. Survival of Terms. This Agreement shall apply to and bind Purchaser and the Company and their respective permitted assignees and
transferees, heirs, legatees, executors, administrators and legal successors. 
 8. Section 83(b) Election.
Purchaser hereby acknowledges that he or she has been informed that, with respect to the exercise of an Option for Unvested Shares, an election (the “Election”) may be filed by the Purchaser with the Internal Revenue Service,
within thirty (30) days of the purchase of the exercised Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on any difference between the purchase price of the exercised Shares and their Fair Market Value on the
date of purchase. In the case of a Nonstatutory Stock Option, this will result in a recognition of taxable income to the Purchaser on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at the time
the Option is exercised over the purchase price for the exercised Shares. Absent such an Election, taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. In the case of
an Incentive Stock Option, such an Election will result in a recognition of income to the Purchaser for alternative minimum tax purposes on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at
the time the option is exercised, over the purchase price for the exercised

  

 36 

 
Shares. Absent such an Election, alternative minimum taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses.
Purchaser is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election under Section 83(b) of the Code. A form of Election under
Section 83(b) is attached hereto as Exhibit C-4 for reference. 
 PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER’S
SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER’S BEHALF. 
 9. Representations. Purchaser has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Purchaser understands that he (and not the Company) shall

 Kazeon Systems, Inc. 
 [Address] 

Dear
                                        :

 As Escrow Agent for both Kazeon Systems, Inc. (the “Company”), and the undersigned purchaser of stock
of the Company (the “Purchaser”), you are hereby authorized and directed to hold the documents delivered to you pursuant to the terms of that certain Restricted Stock Purchase Agreement (the
“Agreement”) between the Company and the undersigned, in accordance with the following instructions: 
 1. In the event the Company and/or any assignee of the Company (referred to collectively for convenience herein as the “Company”) exercises the Company’s repurchase option set forth in the Agreement, the Company
shall give to Purchaser and you a written notice specifying the number of shares of stock to be purchased, the purchase price, and the time for a closing hereunder at the principal office of the Company. Purchaser and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in accordance with the terms of said notice. 
 2.
At the closing, you are directed (a) to date the stock assignments necessary for the transfer in question, (b) to fill in the number of shares being transferred, and (c) to deliver the stock assignments, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its assignee, against the simultaneous delivery to you of the purchase price (by cash, a check, or some combination thereof) for the number of shares of stock being purchased
pursuant to the exercise of the Company’s repurchase option. 
 3. Purchaser irrevocably authorizes the Company to deposit
with you any certificates evidencing shares of stock to be held by you hereunder and any additions and substitutions to said shares as defined in the Agreement. Purchaser does hereby irrevocably constitute and appoint you as Purchaser’s
attorney-in-fact and agent for the term of this escrow to execute with respect to such securities all documents necessary or appropriate to make such securities negotiable and to complete any transaction herein contemplated, including but not
limited to the filing with any applicable state blue sky authority of any required applications for consent to, or notice of transfer of, the securities. Subject to the provisions of this paragraph 3, Purchaser shall exercise all rights and
privileges of a stockholder of the Company while the stock is held by you. 
 4. Upon written request of the Purchaser, but no
more than once per calendar year, unless the Company’s repurchase option has been exercised, you will deliver to Purchaser a certificate or certificates representing so many shares of stock as are not then subject to the

  

 39 

 
Company’s repurchase option. Within 120 days after cessation of Purchaser’s continuous employment by or services to the Company, or any parent or subsidiary of the Company, you will
deliver to Purchaser a certificate or certificates representing the aggregate number of shares held or issued pursuant to the Agreement and not purchased by the Company or its assignees pursuant to exercise of the Company’s repurchase option.

 5. If at the time of termination of this escrow you should have in your possession any documents, securities, or other
property belonging to Purchaser, you shall deliver all of the same to Purchaser and shall be discharged of all further obligations hereunder. 
 6. Your duties hereunder may be altered, amended, modified or revoked only by a writing signed by all of the parties hereto. 
 7. You shall be obligated only for the performance of such duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably
believed by you to be genuine and to have been signed or presented by the proper party or parties. You shall not be personally liable for any act you may do or omit to do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting in
good faith, and any act done or omitted by you pursuant to the advice of your own attorneys shall be conclusive evidence of such good faith. 
 8. You are hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person or corporation, excepting only orders or process of courts of law and are
hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case you obey or comply with any such order, judgment or decree, you shall not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction. 
 9. You shall not be liable in any respect on account of the identity, authorities or rights of the parties executing or delivering or
purporting to execute or deliver the Agreement or any documents or papers deposited or called for hereunder. 
 10. You shall
not be liable for the outlawing of any rights under the Statute of Limitations with respect to these Joint Escrow Instructions or any documents deposited with you. 
 11. You shall be entitled to employ such legal counsel and other experts as you may deem necessary properly to advise you in connection with your obligations hereunder, may rely upon the advice of such
counsel, and may pay such counsel reasonable compensation therefor. 
 12. Your responsibilities as Escrow Agent hereunder shall
terminate if you shall cease to be an officer or agent of the Company or if you shall resign by written notice to each party. In the event of any such termination, the Company shall appoint a successor Escrow Agent. 
  

 40 

 13. If you reasonably require other or further instruments in connection with these Joint
Escrow Instructions or obligations in respect hereto, the necessary parties hereto shall join in furnishing such instruments. 
 14. It is understood and agreed that should any dispute arise with respect to the delivery and/or ownership or right of possession of the securities held by you hereunder, you are authorized and directed to retain in your possession without
liability to anyone all or any part of said securities until such disputes shall have been settled either by mutual written agreement of the parties concerned or by a final order, decree or judgment of a court of competent jurisdiction after the
time for appeal has expired and no appeal has been perfected, but you shall be under no duty whatsoever to institute or defend any such proceedings. 
 15. Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States Post Office, by registered or
certified mail with postage and fees prepaid, addressed to each of the other parties thereunto entitled at the following addresses or at such other addresses as a party may designate by ten days’ advance written notice to each of the other
parties hereto. 
 16. By signing these Joint Escrow Instructions, you become a party hereto only for the purpose of said Joint
Escrow Instructions; you do not become a party to the Agreement. 
 17. This instrument shall be binding upon and inure to the
benefit of the parties hereto, and their respective successors and permitted assigns. 
 18. These Joint Escrow Instructions
shall be governed by the internal substantive laws, but not the choice of law rules, of California.

	II.	AGREEMENT 

 1.
Grant of Option. The Plan Administrator of the Company hereby grants to the Optionee named in the Notice of Grant (the “Optionee”), an option (the “Option”) to purchase the number of Shares set
forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to
Section 14(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an
Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option
(“NSO”). 
 2. Exercise of Option. 
 (a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice
of Grant and with the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of Exercise. This Option
shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which shall state the election to exercise the Option, the number of Shares with respect to which the
Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed
to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee
on the date on which the Option is exercised with respect to such Shares. 
 3. Optionee’s Representations. In the
event the Shares have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option,
deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B. 
 4.
Lock-Up Period. Optionee hereby agrees that Optionee shall not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to

  

 45 

 
sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any
swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by Optionee (other than those included in the
registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of any registration statement of the
Company filed under the Securities Act. 
 Optionee agrees to execute and deliver such other agreements as may be reasonably
requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other
securities) of the Company, Optionee shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s
securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may
be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of
Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Optionee agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by
this Section. 
 5. Method of Payment. Payment of the aggregate Exercise Price will be required upon exercise and will
consist solely of (a) cash or check, to the extent permitted under Applicable Laws, or (b) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan, on or after
(x) the closing of the Company’s first firm commitment underwritten public offering of its Common Stock registered under the Securities Act, or (y) a Change in Control in which the successor corporation has equity securities that are
publicly traded. 
 6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been
approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 
 7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent
or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
 8. Term of Option. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such
term only in accordance with the Plan and the terms of this Option. 
  

 46 

 9. Withholding Taxes. Optionee agrees to make appropriate arrangements with the
Company (or the Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all Federal / central, state, local and foreign income and employment tax withholding requirements as well as social security charges applicable to the
Option exercise or the disposition of any Shares acquired upon exercise. In this regard, Optionee authorizes the Company (and/or the Parent or Subsidiary employing or retaining Optionee) to withhold all applicable taxes legally payable by Optionee
from the Optionee’s wages or other cash compensation paid to Optionee by the Company (and/or the Parent or Subsidiary employing or retaining Optionee) or from proceeds from the sale of Shares acquired upon exercise of the Option in an amount
sufficient to cover such tax obligations. Optionee acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise. 
 10. Acknowledgements. 
 (a) Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and
provisions thereof. Optionee has reviewed the Plan and this Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Optionee hereby
agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option. Optionee further agrees to notify the Company upon any change in the residence address
indicated below. 
 (b) The Company (and not the Optionee’s employer) is granting the Option. The Company will administer
the Plan from outside Optionee’s country of residence and that United States of America law along with FEMA and other applicable Indian laws will govern all Options granted under the Plan. 
 (c) That benefits and rights provided under the Plan are wholly discretionary and, although provided by the Company, do not constitute
regular or periodic payments. The benefits and rights provided under the Plan are not to be considered part of Optionee’s salary or compensation for purposes of calculating any severance, resignation, redundancy or other end of service
payments, vacation, bonuses, long-term service awards, indemnification, pension or retirement benefits, or any other payments, benefits or rights of any kind. Optionee waives any and all rights to compensation or damages as a result of the
termination of employment with the Company for any reason whatsoever insofar as those rights result or may result from: 
 (i)
the loss or diminution in value of such rights under the Plan, or 
 (ii) Optionee ceases to have any rights under, or ceases
to be entitled to any rights under the Plan as a result of such termination. 
 (d) The grant of the Option, and any future
grant of Options under the Plan is entirely voluntary, and at the complete discretion of the Company. Neither the grant of the Option nor any future grant of an Option by the Company will be deemed to create any obligation to grant any further
Options, whether or not such a reservation is explicitly stated at

  

 47 

 
the time of such a grant. The Company has the right, at any time to amend, suspend or terminate the Plan. 
 (e) The Plan will not be deemed to constitute, and will not be construed by Optionee to constitute, part of the terms and conditions of employment, and that the Company will not incur any liability of any
kind to Optionee as a result of any change or amendment, or any cancellation, of the Plan at any time. 
 (f) Participation in
the Plan will not be deemed to constitute, and will not be deemed by Optionee to constitute, an employment or labor relationship of any kind with the Company. 
 (g) By entering into this Option Agreement, and as a condition of the grant of the Option, Optionee consents to the collection, use, and transfer of personal data as described in this subsection to the
full extent permitted by and in full compliance with Applicable Laws. 
 (i) Optionee understands that the Company and its
Subsidiaries hold certain personal information about the Optionee, including, but not limited to, name, home address and telephone number, date of birth, social insurance number, salary, nationality, job title, any Shares or directorships held in
the Company, details of all Options or other entitlement to Shares awarded, canceled, exercised, vested, unvested, or outstanding in Optionee’s favor, for the purpose of managing and administering the Plan (“Data”).

 (ii) Optionee further understands that the Company and/or its Subsidiaries will transfer Data among themselves as necessary
for the purposes of implementation, administration, and management of Optionee’s participation in the Plan, and that the Company and/or its Subsidiary may each further transfer Data to any third parties assisting the Company in the
implementation, administration, and management of the Plan (“Data Recipients”). 
 (iii) Optionee
understands that these Data Recipients may be located in Optionee’s country of residence or elsewhere, such as the United States. Optionee authorizes the Data Recipients to receive, possess, use, retain, and transfer Data in electronic or other
form, for the purposes of implementing, administering, and managing Optionee’s participation in the Plan, including any transfer of such Data, as may be required for the administration of the Plan and/or the subsequent holding of Shares on
Optionee’s behalf, to a broker or third party with whom the Shares acquired on exercise may be deposited. 
 (iv) Optionee
understands that Optionee may, at any time, review the Data, request that any necessary amendments be made to it, or withdraw Optionee’s consent herein in writing by contacting the Company. Optionee further understands that withdrawing consent
may affect Optionee’s ability to participate in the Plan. 
 (h) Optionee has received the terms and conditions of this
Option Agreement and any other related communications, and Optionee consents to having received these documents in English. 
  

 48 

 11. Entire Agreement; Governing Law. The Plan is incorporated herein by reference.
The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject
matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee. This agreement is governed by the internal substantive laws but not the choice of law rules of
California. 
 12. No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES
PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND
AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT
ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof, and
hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option. Optionee further agrees to

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price
(“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (d) Payment.
Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an
assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are
not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 120 days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this
Section shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the
Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on
the Optionee’s death by will or intestacy to the Optionee’s immediate family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family”
as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and
there shall be no further transfer of such Shares except in accordance with the terms of this Section. 
 (g) Termination of
Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor
corporation has equity securities that are publicly traded. 
 6. Tax Consultation. Optionee understands that Optionee
may suffer adverse tax consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee

  

 51 

 
represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the
Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT
BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION
IS IN COMPLIANCE THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A
RIGHT OF FIRST REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER
RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A PERIOD NOT TO EXCEED 180 DAYS FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER
WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b) Stop-Transfer Notices. Optionee agrees that, in
order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make
appropriate notations to the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall not be
required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right to

  

 52 

 
vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 
 8. Successors and Assigns. The Company may assign any of its rights under this Exercise Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors

 9. Interpretation. Any dispute regarding the interpretation of this Exercise Notice shall be submitted by Optionee or by the Company
forthwith to the Administrator which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is governed by the internal substantive laws but not the choice of law rules,
of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Option Agreement will continue in full force and effect. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein by reference. This Exercise Notice, the Plan, the Option
Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with

 EXHIBIT B 
 INVESTMENT REPRESENTATION STATEMENT 
  

			
	 OPTIONEE:
	  	___________________________
		
	 COMPANY:
	  	KAZEON SYSTEMS, INC.
		
	 SECURITY:
	  	COMMON STOCK
		
	 AMOUNT:
	  	_________ SHARES
		
	 DATE:
	  	___________________________

 In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following: 
 (a) Optionee is aware of the Company’s business affairs and financial
condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a
view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for
the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further
understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under
no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with any legend required under applicable state securities laws. 
 (c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies
under Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject

  

 54 

 
to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may
require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s
transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company,
(3) the amount of Securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable. 
 In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate
of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above. 
 (d) Optionee further understands that in the
event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules
144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or
701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.
Optionee understands that no assurances can be given that any such other registration exemption will be available in such event.

 58 

 
death. During the life of the Optionee, Options shall be only be exercisable by the Optionee. If the Administrator in its sole discretion makes an Option transferable, such Option may only be
transferred (i) by will, (ii) by the laws of descent and distribution, or (iii) to family members (within the meaning of Rule 701 of the Securities Act) through gifts or domestic relations orders, as permitted by Rule 701 of the
Securities Act.”

Change in Control, each outstanding Option may be replaced (either through assumption or substitution) by an equivalent option granted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the
successor corporation in a merger or Change in Control does not grant a replacement option for the Option, then the Option shall vest fully in the Optionee and the Optionee shall have the right to exercise the Option even though it would not
otherwise be vested or exercisable. If an Option is not replaced in the event of a merger or Change in Control, the Administrator shall notify the Optionee in writing or electronically that this Option shall be exercisable for a period of fifteen
(15) days from the date of such notice, and the Option shall terminate upon expiration of such period. For the purposes of this paragraph, the Option shall be considered replaced if, following the merger or Change in Control, the option confers

holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however,

 2. Exercise of Option. 
 (a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice
of Grant and with the applicable provisions of the Sub-Plan, this Option Agreement, the Joint Election and the Section 431 Election. 
 (b) Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) which shall state
the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of
the aggregate Exercise Price, the Option Tax Liability and the Secondary NIC Liability as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by payment
of the Exercise Price, the Option Tax Liability and the Secondary NIC Liability. 
 (c) Compliance with Law. No Shares

which the Option is exercised with respect to such Shares. 
 (d) Withholding Taxes. In the event that the Company
determines that it is required to account to HM Revenue & Customs for income tax (under PAYE) or any other taxation provisions and primary class 1 NICs in the United Kingdom to the extent arising from the grant, exercise, assignment,
release, cancellation or any other disposal of an Option or the Secondary NIC Liability as a result of the exercise of this Option, the Optionee, as condition to the exercise of this Option, shall make arrangements satisfactory to the Company to
enable it to satisfy all such requirements in accordance with sections 9 and 10 of this Option Agreement and the terms of the Joint Election. The Optionee shall also make arrangements satisfactory to the Company to enable it to satisfy any
requirement to account for tax that may arise in connection with the disposition of Shares purchased by exercising this option.

with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B. 
 4. Lock-Up Period. Optionee hereby agrees that Optionee shall not offer, pledge, sell, contract to sell, sell any option or contract

Optionee (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective
date of any registration statement of the Company filed under the Securities Act. 
 Optionee agrees to execute and deliver such
other agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the
underwriters of Common Stock (or other securities) of the Company, Optionee shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any
public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section shall not apply to a registration relating solely to employee benefit plans on Form S-1
or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer
instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Optionee agrees that any transferee of the Option or shares acquired
pursuant to the Option shall be bound by this Section.

Tax Liability and the Secondary NIC Liability shall be by any of the following, or a combination thereof, at the election of the Optionee: 
 (a) cash or cheque; or 
 (b) consideration received by the Company under a formal
cashless exercise program adopted by the Company in connection with the Plan. 
 6. Restrictions on Exercise. This Option
may not be exercised until such time as the Sub-Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of
any Applicable Law. 
 7. Non-Transferability of Option. This Option may not be transferred in any manner during the
lifetime of the Optionee and may be exercised during the lifetime of the Optionee only by the Optionee. In the event of the Optionee’s death, this Option may be exercised by the Optionee’s personal representative(s). The terms of the
Sub-Plan, this Option Agreement, the Joint Election and the Section 431 Election shall be binding upon the personal representative(s) of the Optionee. 
  

 63 

 8. Term of Option. This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with the Sub-Plan, this Option Agreement and the Joint Election. 
 9. Optionee’s Tax Indemnity. 
 (a) Indemnity. To the extent
permitted by law, the Optionee hereby agrees to indemnify and keep indemnified the Company, and the Company as trustee for and on behalf of any related corporation, in respect of any liability or obligation of the Company and/or any related
corporation to account for income tax (under PAYE) or any other taxation provisions and primary class 1 NICs in the United Kingdom (the “Option Tax Liability”) to the extent arising from the grant, exercise, assignment, release,
cancellation or any other disposal of an Option or arising out of the acquisition, retention and disposal of the Shares acquired pursuant to this Option. 
 (b) No Obligation to Issue Shares. The Company shall not be obliged to allot and issue any Shares or any interest in Shares pursuant to the exercise of this option unless and until the Optionee has
paid to the Company such sum as is, in the opinion of the Company, sufficient to indemnify the Company in full against the Option Tax Liability, or the Optionee has made such other arrangement as in the opinion of the Company will ensure that the
full amount of any Option Tax Liability will be recovered from the Optionee within such period as the Company may then determine. 
 (c) Right of Retention. In the absence of any such other arrangement being made, the Company shall have the right to retain out of the aggregate number of shares to which the Optionee would have otherwise been entitled upon the
exercise of this option, such number of Shares as, in the opinion of the Company, will enable the Company to sell as agent for the Optionee (at the best price which can reasonably expect to be obtained at the time of the sale) and to pay over to the
Company sufficient monies out of the net proceeds of sale, after deduction of all fees, commissions and expenses incurred in relation to such sale, to satisfy the Optionee’s liability under such indemnity. 
 10. Employer’s NICs. 
 (a) Joint Election. As a condition of the exercise of this Option, the Optionee shall have signed a joint election (in such terms and such form as provided in paragraphs 3A and 3B of Schedule 1 to
the Social Security Contributions and Benefits Act 1992) (“Joint Election”) which has been approved by HM Revenue & Customs for the transfer of the whole or any liability of the Optionee’s employer to employer’s Class 1
NICs (“Secondary NIC Liability”). 
 (b) Section 431 Election. As a further condition of the exercise of
his Option, the Optionee shall have signed a Section 431 election under Section 431 ITEPA in the form set out in Exhibit C or in such other form as may be determined by HM Revenue & Customs from time to time. 
  

 64 

 11. Entire Agreement; Governing Law. The Sub-Plan, the Joint Election and the
Section 431 Election are incorporated herein by reference. The Sub-Plan, this Option Agreement, the Joint Election and the Section 431 Election constitute the entire agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the
Company and Optionee. This agreement is governed by the internal substantive laws but not the choice of law rules of the State of California. 
 12. No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE
WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE SUB-PLAN, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING
SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE
COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 13.
Optionee acknowledges receipt of a copy of the Sub-Plan, this Option Agreement and the Joint Election and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and
provisions thereof. Optionee has reviewed the Sub-Plan, this Option Agreement, the Joint Election and the Section 431 Election in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option Agreement
and fully understands all provisions of this Option Agreement. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Sub-Plan, this Option
Agreement, the Joint Election and the Section 431 Election. Optionee further agrees to notify the Company upon any change in the residence address indicated below.

 1. Exercise of Option. Effective as of today,
                        ,             , the undersigned
(“Optionee”) hereby elects to exercise Optionee’s option to purchase [            ] shares of the Common Stock (the “Shares”) of
Kazeon Systems, Inc. (the “Company”) under and pursuant to the UK Sub-Plan of the Company’s 2003 Stock Plan (the “Plan”) and the Stock Option Agreement dated grantdate (the

 2. Delivery of Payment. Optionee herewith
delivers to the Company the full payment for the Shares, the Option Tax Liability and the Secondary NIC Liability, as set forth in the Option Agreement. 
 3. Representations of Optionee. Optionee acknowledges that Optionee has received, read and understood the Sub-Plan, the Option Agreement and the Joint Election (as defined in the Option Agreement)
and agrees to abide by and be bound by their terms and conditions. 
 4. Rights as Stockholder. Until the issuance of the
Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned
Stock, notwithstanding the exercise of the Option. The Shares shall be issued to the Optionee as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for
which the record date is prior to the date of issuance except as provided in Section 13 of the Sub-Plan. 
 5.
Company’s Right of First Refusal. Before any Shares held by Optionee or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift
or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the
“Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”);
(iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder

  

 66 

 
proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 
 (b) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its
assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below. 
 (c) Purchase Price. The purchase price (“Purchase Price”) for the
Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board
of Directors of the Company in good faith. 
 (d) Payment. Payment of the Purchase Price shall be made, at the option of
the Company or its assignee(s), in cash (by cheque) within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided
in this Section, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is completed within 120 days after the date of the Notice,
that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such
Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First
Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family
Transfers. Anything to the contrary contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s immediate
family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or
sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this
Section. 
 (g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon
the earlier of (i) the first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 
 6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s purchase
or disposition of the Shares. Optionee

  

 67 

 
represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the
Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT
BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION
IS IN COMPLIANCE THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A
RIGHT OF FIRST REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER
RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A PERIOD NOT TO EXCEED 180 DAYS FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER
WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b) Stop-Transfer Notices. Optionee agrees that, in
order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make
appropriate notations to the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall not be
required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right to

  

 68 

 
vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 
 8. Successors and Assigns. The Company may assign any of its rights under this Exercise Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors
and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon Optionee and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute regarding the interpretation of this Exercise Notice shall be submitted by Optionee or by the Company
forthwith to the Administrator which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is governed by the internal substantive laws but not the choice of law rules,
of the State of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Option Agreement will continue in full force and effect. 
 11. Entire Agreement. The Sub-Plan, the Option Agreement, the Joint Election and the Section 431 Election are incorporated
herein by reference. This Exercise Notice, the Sub-Plan, the Option Agreement, the Joint Election, the Section 431 Election and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject
matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing
signed by the Company and Optionee.

 In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following: 
 (a) Optionee is aware of the Company’s business affairs and financial
condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a
view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for
the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further
understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under
no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with any legend required under applicable state securities laws. 
 (c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies
under Rule 701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the

  

 70 

 
reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require)
the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or
in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of
Securities being sold during any three month period not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable. 
 In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144,
which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of
acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately
above. 
 (d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not
satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and
Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing
that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

 Exhibit C 
  

	
	 
	 Joint Election under s431 ITEPA 2003 for full or partial disapplication of
 Chapter 2 Income Tax (Earnings and Pensions) Act 2003
  

 One Part Election 
 1. Between 
  

			
		
	 the Employee
	  	[insert name of employee]
		
	 whose National Insurance Number is
	  	[insert NINO]
		
	 and
	  	
		
	 the Company (who is the Employee’s employer)
	  	Kazeon Systems Europe Limited
		
	 of Company Registration Number
	  	06023883

 2. Purpose of Election 
 This joint election is made pursuant to section 431(1) or 431(2) Income Tax (Earnings and Pensions) Act 2003 (ITEPA) and applies where
employment-related securities, which are restricted securities by reason of section 423 ITEPA, are acquired. 
 The effect of an
election under section 431(1) is that, for the relevant Income Tax and NIC purposes, the employment-related securities and their market value will be treated as if they were not restricted securities and that sections 425 to 430 ITEPA do not apply.
An election under section 431(2) will ignore one or more of the restrictions in computing the charge on acquisition. Additional Income Tax will be payable (with PAYE and NIC where the securities are Readily Convertible Assets). 
  

	
	 Should the value of the securities fall following the acquisition, it is
possible that Income Tax/NIC that would have arisen because of any future chargeable event (in the absence of an election) would have been less than the Income Tax/NIC due by reason of this election. Should this be the case, there is no Income
Tax/NIC relief available under Part 7 of ITEPA 2003; nor is it available if the securities acquired are subsequently transferred, forfeited or revert to the original owner.

  

 72 

 3. Application 
 This joint election is made not later than 14 days after the date of acquisition of the securities by the employee and applies to: 
  

			
		
	 Number of securities
	  	[insert number]
		
	 Description of securities
	  	Common Stock of Kazeon Systems, Inc.
		
	 Name of issuer of securities
	  	Kazeon Systems, Inc.
		
	 *       [insert date of option]
	  	
	
	 *       to be acquired by the Employee after [dd/mm/yyyy] under the terms
of the UK Sub-Plan of the Kazeon Systems, Inc. 2003 Stock Plan

		
		  	(* delete as appropriate)

 4. Extent of Application 
 This election disapplies: 
  

	 	*	S.431(1) ITEPA: All restrictions attaching to the securities, or 

 5. Declaration 
 This election will become irrevocable upon the later of its
signing or the acquisition (* and each subsequent acquisition) of employment-related securities to which this election applies. 
  

			
		
		  	(* delete as appropriate)

  

 73 

 In signing this joint election, we agree to be bound by its terms as stated above.

     ] of [Insert Address] (the “Optionee” which shall include his executors or administrators in the case of his death). 

 INTRODUCTION 
  

	(A)	The Optionee may be granted options (each one an “Option”) to acquire shares of common stock in the Company (the “Shares”) on terms to be set out in
stock option agreements to be issued to the Optionee and which will be subject to the UK Sub-Plan of the Kazeon Systems, Inc. 2003 Stock Plan (the “Plan”). 

  

	(B)	The grant of an Option will only take place after the Optionee has executed this joint election (the “Joint Election”). This Joint Election is in an approved
format. The exercise, cancellation, release, assignment or other disposal of an Option is subject to the Optionee entering into this Joint Election. 

  

	(C)	The Optionee is currently an employee of the Employer. 

  

	(D)	The exercise, release, cancellation, assignment or other disposal of an Option (a “Trigger Event”) (whether in whole or in part), may result in the Employer
or, if and to the extent that there is a change in law, any other company or person who becomes the secondary contributor for National Insurance contributions (“NIC”) purposes at the time of such Trigger Event having a liability to pay
employer’s (secondary) Class I NICs (or any tax or social security premiums which may be introduced in substitution or in addition thereto) in respect of such Trigger Event. 

  

	(E)	Where the context so admits, any reference in this Joint Election: 

  

	 	(i)	to the singular number shall be construed as if it referred also to the plural number and vice versa; 

  

	 	(ii)	to the masculine gender shall be construed as though it referred also to the feminine gender; 

  

 76 

	 	(iii)	to a statute or statutory provision shall be construed as if it referred also to that statute or provision as for the time being amended or re-enacted; and

  

	 	(iv)	Shares means shares of common stock of the Company. 

 AGREED TERMS 
  

	1.	Joint Election 

  

	1.1	It is a condition of the grant, exercise, cancellation, release, assignment or other disposal of an Option that the Optionee has entered into this Joint Election with
the Employer. 

  

	1.2	The Optionee, the Company and the Employer elect to transfer the liability (the “Liability”) for all of the employer’s (Secondary) Class I NICs, referred
to in (D) above and charged on payments or other benefits arising on a Trigger Event and treated as remuneration and earnings pursuant to section 4(4)(a) of the Social Security Contributions and Benefit Act 1992 (“SSCBA”) to the
Optionee. This Joint Election is made pursuant to an arrangement authorised by paragraph 3B, Schedule 1 of the SSCBA. 

  

	1.3	This Joint Election does not apply in relation to any liability, or any part of any liability, arising as a result of regulations being given retrospective effect by
virtue of section 4B(2) of the Social Security Contributions and Benefits Act 1992 or the Social Security Contributions and Benefits (Northern Ireland) Act 1992. 

  

	2.	Restriction on registration until liability paid by Optionee 

 The Optionee hereby agrees that no Shares shall be registered in his name until he has met the Liability as a result of a Trigger Event in accordance with this Joint Election. 
  

	3.	Payment 

  

	3.1	Where, in relation to an Option, the Optionee is liable, or is in accordance with current practice at the date of the Trigger Event believed by the Employer to be
liable (where it is believed that the shares under option are readily convertible assets), to account to HM Revenue & Customs for the Liability, the Optionee and the Employer agree that, upon receipt of the funds to meet the Liability from
the Optionee, that such funds to meet the Liability shall be paid to the Collector of Taxes or other relevant taxation authority by the Employer on the Optionee’s behalf within 14 days of the end of the income tax month in which the gain on the
Option was made (the “14 day period”) and for the purposes of securing payment of the Liability the Optionee will on the occurrence of a Trigger Event: 

  

 77 

	 	(a)	pay to the Employer a cash amount equal to the Liability; and/or 

  

	 	(b)	suffer a deduction from salary or other remuneration due to the Optionee such deduction being in an amount not exceeding the Liability; and/or 

 

	 	(c)	at the request of the Company enter into such arrangement or arrangements necessary or expedient with such person or persons (including the appointment of a nominee on
behalf of the Optionee) to effect the sale of Shares acquired through the exercise of the Option to cover all or any part of the Liability and use the proceeds to pay the Employer a cash amount equal to the Liability.

 Exhibit 10.5 
 KAZEON SYSTEMS, INC. 
 2008 EQUITY INCENTIVE PLAN 
 (As amended April 6, 2009) 
 1. Purposes of the Plan. The purposes of this Plan are: 
  

	 	•	 	 to attract and retain the best available personnel for positions of substantial responsibility, 

  

	 	•	 	 to provide additional incentive to Employees, Directors and Consultants, and 

  

	 	•	 	 to promote the success of the Company’s business. 

 The Plan permits the grant of Incentive Stock Options, Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock and Restricted Stock Units. 
 2. Definitions. As used herein, the following definitions will apply: 
 (a) “Administrator” means the Board or any of its Committees as will be administering the Plan, in accordance with
Section 4 of the Plan. 
 (b) “Applicable Laws” means the requirements relating to the administration of
equity-based awards under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed or quoted and the applicable laws of any foreign country or
jurisdiction where Awards are, or will be, granted under the Plan. 
 (c) “Award” means, individually or
collectively, a grant under the Plan of Options, Stock Appreciation Rights, Restricted Stock, or Restricted Stock Units. 
 (d)
“Award Agreement” means the written or electronic agreement setting forth the terms and provisions applicable to each Award granted under the Plan. The Award Agreement is subject to the terms and conditions of the Plan. 

(e) “Board” means the Board of Directors of the Company. 
 (f) “Change in Control” means the occurrence of any of the following events: 
 (i) Change in Ownership of the Company. A change in the ownership of the Company which occurs on the date that any one person, or
more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than 50% of the total voting power of the stock of the Company, except
that any change in the ownership of the stock of the Company as a result of a

 
private financing of the Company that is approved by the Board will not be considered a Change in Control; or 
 (ii) Change in Effective Control of the Company. If the Company has a class of securities registered pursuant to Section 12 of the Exchange Act, a change in the effective control of the
Company which occurs on the date that a majority of members of the Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of
the appointment or election. For purposes of this clause (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control;
or 
 (iii) Change in Ownership of a Substantial Portion of the Company’s Assets. A change in the ownership of a
substantial portion of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets from the
Company that have a total gross fair market value equal to or more than 50% of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions. For purposes of this subsection (iii), gross
fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 
 For purposes of this Section 2(f), persons will be considered to be acting as a group if they are owners of a corporation that enters
into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 
 Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Code Section 409A, as it has been and may be amended from time to
time, and any proposed or final Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be promulgated thereunder from time to time. 
 Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its
sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction. 
 (g) “Code” means the Internal Revenue Code of 1986, as amended. Any reference to a section of the Code herein will be a
reference to any successor or amended section of the Code.

 2 

 (j) “Company” means Kazeon Systems, Inc., a Delaware corporation, or any

that in the case of Awards other than Incentive Stock Options, the Administrator in its discretion may determine whether a permanent and total disability exists in accordance with uniform and non-discriminatory standards adopted by the Administrator
from time to time. 
 (n) “Employee” means any person, including officers and Directors, employed by the
Company or any Parent or Subsidiary of the Company. Neither service as a Director nor payment of a director’s fee by the Company will be sufficient to constitute “employment” by the Company. 
 (o) “Exchange Act” means the Securities Exchange Act of 1934, as amended. 
 (p) “Exchange Program” means a program under which (i) outstanding Awards are surrendered or cancelled in exchange for
Awards of the same type (which may have higher or lower exercise prices and different terms), Awards of a different type, and/or cash, (ii) Participants would have the opportunity to transfer any outstanding Awards to a financial institution or
other person or entity selected by the Administrator, and/or (iii) the exercise price of an outstanding Award is reduced or increased. The Administrator will determine the terms and conditions of any Exchange Program in its sole discretion.

 (q) “Fair Market Value” means, as of any date, the value of Common Stock determined as follows: 

(i) If the Common Stock is listed on any established stock exchange or a national market system, including without limitation the Nasdaq
Global Select Market, the Nasdaq Global Market or the Nasdaq Capital Market of The Nasdaq Stock Market, its Fair Market Value will be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on such exchange
or system on the day of determination, as reported in The Wall Street Journal or such other source as the Administrator deems reliable; 
 (ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, the Fair Market Value of a Share will be the mean between the high bid and low asked
prices for the Common Stock on the day of determination (or, if no bids and asks were reported on that date, as applicable, on the last trading date such bids and asks were reported), as reported in The Wall Street Journal or such other
source as the Administrator deems reliable; or 
  

 3 

 (iii) In the absence of an established market for the Common Stock, the Fair Market Value
will be determined in good faith by the Administrator.

its terms qualifies and is otherwise intended to qualify as an incentive stock option within the meaning of Code Section 422 and the regulations promulgated thereunder.

Incentive Stock Option. 
 (t) “Option” means a stock option granted pursuant to the Plan. 
 (u) “Parent” means a “parent corporation,” whether now or hereafter existing, as defined in Code
Section 424(e). 
 (v) “Participant” means the holder of an outstanding Award. 
 (w) “Period of Restriction” means the period during which the transfer of Shares of Restricted Stock are subject to
restrictions and therefore, the Shares are subject to a substantial risk of forfeiture. Such restrictions may be based on the passage of time, the achievement of target levels of performance, or the occurrence of other events as determined by the
Administrator. 
 (x) “Plan” means this 2008 Equity Incentive Plan. 
 (y) “Restricted Stock” means Shares issued pursuant to an Award of Restricted Stock under Section 8 of the Plan, or

 (cc) “Stock Appreciation Right” means an Award, granted alone or in connection with an Option, that pursuant to
Section 7 is designated as a Stock Appreciation Right. 
 (dd) “Subsidiary” means a “subsidiary
corporation,” whether now or hereafter existing, as defined in Code Section 424(f). 
 3. Stock Subject to the
Plan. 
  

 4 

 (a) Stock Subject to the Plan. Subject to the provisions of Section 13 of the
Plan, the maximum aggregate number of Shares that may be subject to Awards and sold under the Plan is (i) 5,597,793 Shares (which equals the number of shares that, as of the date hereof, have been reserved but not issued pursuant to any
awards granted under the Kazeon Systems, Inc. 2003 Stock Plan (the “2003 Plan”) and are not subject to any awards granted thereunder, plus (ii) any Shares subject to stock options or similar awards granted under the 2003 Plan
that expire or otherwise terminate without having been exercised in full and Shares issued pursuant to awards granted under the 2003 Plan that are forfeited to or repurchased by the Company, with the maximum number of shares to be added to the Plan
pursuant to clauses (i) and (ii) equal to 12,019,818 Shares. The Shares may be authorized but unissued, or reacquired Common Stock. 
 (b) Lapsed Awards. If an Award expires or becomes unexercisable without having been exercised in full, is surrendered pursuant to an Exchange Program, or, with respect to Restricted Stock or
Restricted Stock Units, is forfeited to or repurchased by the Company due to the failure to vest, the unpurchased Shares (or for Awards other than Options or Stock Appreciation Rights the forfeited or repurchased Shares) which were subject thereto
will become available for future grant or sale under the Plan (unless the Plan has terminated). With respect to Stock Appreciation Rights, only Shares actually issued pursuant to a Stock Appreciation Right will cease to be available under the Plan;
all remaining Shares under Stock Appreciation Rights will remain available for future grant or sale under the Plan (unless the Plan has terminated). Shares that have actually been issued under the Plan under any Award will not be returned to the
Plan and will not become available for future distribution under the Plan; provided, however, that if Shares issued pursuant to Awards of Restricted Stock or Restricted Stock Units are repurchased by the Company or are forfeited to the Company due
to the failure to vest, such Shares will become available for future grant under the Plan. Shares used to pay the exercise price of an Award or to satisfy the tax withholding obligations related to an Award will become available for future grant or
sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under the Plan. Notwithstanding the foregoing and, subject
to adjustment as provided in Section 13, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Code
Section 422 and the Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Section 3(b). 
 (c) Share Reserve. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan.

 4. Administration of the Plan. 
 (a) Procedure. 
 (i) Multiple Administrative Bodies. Different
Committees with respect to different groups of Service Providers may administer the Plan. 
  

 5 

 (ii) Other Administration. Other than as provided above, the Plan will be
administered by (A) the Board or (B) a Committee, which Committee will be constituted to satisfy Applicable Laws. 
 (b) Powers of the Administrator. Subject to the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its
discretion: 
 (i) to determine the Fair Market Value; 
 (ii) to select the Service Providers to whom Awards may be granted hereunder; 
 (iii) to determine the number of Shares to be covered by each Award granted hereunder; 
 (iv) to approve forms of Award Agreements for use under the Plan; 
 (v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine; 
 (vi) to institute and determine the terms and conditions of an Exchange Program; 
 (vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 
 (viii) to prescribe,
amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of satisfying applicable foreign laws; 
 (ix) to modify or amend each Award (subject to Section 18(c) of the Plan), including but not limited to the discretionary authority to
extend the post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(d)); 
 (x) to allow Participants to satisfy withholding tax obligations in a manner prescribed in Section 14; 
 (xi) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator; 
  

 6 

 (xii) to allow a Participant to defer the receipt of the payment of cash or the delivery of
Shares that otherwise would be due to such Participant under an Award; and 
 (xiii) to make all other determinations deemed
necessary or advisable for administering the Plan. 
 (c) Effect of Administrator’s Decision. The
Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards. 
 5. Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, and Restricted Stock Units may be granted to Service Providers. Incentive Stock Options may be granted only
to Employees. 
 6. Stock Options. 
 (a) Grant of Options. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may grant Options in such amounts as the Administrator, in its sole
discretion, will determine. 
 (b) Option Agreement. Each Award of an Option will be evidenced by an Award Agreement that
will specify the exercise price, the term of the Option, the number of Shares subject to the Option, the exercise restrictions, if any, applicable to the Option, and such other terms and conditions as the Administrator, in its sole discretion, will
determine. 
 (c) Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option
or a Nonstatutory Stock Option. Notwithstanding such designation, however, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during
any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(c), Incentive Stock
Options will be taken into account in the order in which they were granted, the Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted, and calculation will be performed in accordance with
Code Section 422 and Treasury Regulations promulgated thereunder. 
 (d) Term of Option. The term of each Option
will be stated in the Award Agreement; provided, however, that the term will be no more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock
Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years
from the date of grant or such shorter term as may be provided in the Award Agreement. 
 (e) Option Exercise Price and
Consideration. 
  

 7 

 (i) Exercise Price. The per Share exercise price for the Shares to be issued
pursuant to the exercise of an Option will be determined by the Administrator, but will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. In addition, in the case of an Incentive Stock Option
granted to an Employee who owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent
(110%) of the Fair Market Value per Share on the date of grant. Notwithstanding the foregoing provisions of this Section 6(e)(i), Options may be granted with a per Share exercise price of less than one hundred percent (100%) of the
Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Code Section 424(a). 
 (ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must
be satisfied before the Option may be exercised. 
 (iii) Form of Consideration. The Administrator will determine the
acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may
consist entirely of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal to the aggregate
exercise price of the Shares as to which such Option will be exercised and provided further that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion;
(5) consideration received by the Company under cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net exercise, (7) such other consideration and method of
payment for the issuance of Shares to the extent permitted by Applicable Laws, or (8) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator will consider if
acceptance of such consideration may be reasonably expected to benefit the Company. 
 (f) Exercise of Option.

 (i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to
the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 
 An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form as the Administrator may specify
from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable tax withholding). Full payment may consist of any consideration and
method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the
Participant and his

  

 8 

 
or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised.
No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 
 Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale
under the Option, by the number of Shares as to which the Option is exercised. 
 (ii) Termination of Relationship as a
Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within thirty
(30) days of termination, or such longer period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is vested on
the date of termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If
after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 
 (iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability,
the Participant may exercise his or her Option within six (6) months of termination, or such longer period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the
Award Agreement) to the extent the Option is vested on the date of termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the
Plan. 
 (iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised within
six (6) months following the Participant’s death, or within such longer period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the
extent that the Option is vested on the date of death, by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to the Participant’s death in a form acceptable to the Administrator. If no such
beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in
accordance with the laws of descent and distribution. Unless otherwise provided by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested

  

 9 

 
portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option
will revert to the Plan. 
 7. Stock Appreciation Rights. 
 (a) Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right may be granted to
Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. 
 (b)
Number of Shares. The Administrator will have complete discretion to determine the number of Shares subject to any Award of Stock Appreciation Rights. 
 (c) Exercise Price and Other Terms. The per Share exercise price for the Shares that will determine the amount of the payment to be received upon exercise of a Stock Appreciation Right as set forth
in Section 7(f) will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the provisions of the Plan, will
have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan. 
 (d)
Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms
and conditions as the Administrator, in its sole discretion, will determine. 
 (e) Expiration of Stock Appreciation
Rights. A Stock Appreciation Right granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(d)
relating to the maximum term and Section 6(f) relating to exercise also will apply to Stock Appreciation Rights. 
 (f)
Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (ii) The number of Shares with respect to which the Stock Appreciation Right is exercised. 
 At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or
in some combination thereof. 
 8. Restricted Stock. 
  

 10 

 (a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the
Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 
 (b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period
of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted
Stock until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this
Section 8 or as the Administrator determines, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction. 
 (d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock
as it may deem advisable or appropriate. 
 (e) Removal of Restrictions. Except as otherwise provided in this
Section 8, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may
determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 
 (f) Voting Rights. During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise.

 (g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of
Restricted Stock will be entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends or distributions are paid in Shares, the Shares will be subject
to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 
 (h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan.

 9. Restricted Stock Units. 
 (a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units,
it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units. 
  

 11 

 (b) Vesting Criteria and Other Terms. The Administrator will 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 Administrator may set vesting criteria based upon the achievement of
Company-wide, business unit, or individual goals (including, but not limited to, continued employment or service), or any other basis determined by the Administrator in its discretion. 
 (c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a
payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a
payout. 
 (d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made as soon as practicable
after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may settle earned Restricted Stock Units in cash, Shares, or a combination of both. 
 (e) Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the Company.

 10. Compliance With Code Section 409A. Awards will be designed and operated in such a manner that they are either
exempt from the application of, or comply with, the requirements of Code Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet the
requirements of Code Section 409A and will be construed and interpreted in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or
deferral thereof, is subject to Code Section 409A the Award will be granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be
subject to the additional tax or interest applicable under Code Section 409A. 
 11. Leaves of
Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of (i) any
leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless
reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then six (6) months following the first (1st) day of such leave, any Incentive Stock Option held by the
Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 
 12. Limited Transferability of Awards. Unless determined otherwise by the Administrator, Awards may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner, including by entering into any short
position, any “put equivalent

  

 12 

 
position” or any “call equivalent position” (as defined in Section 16a-1(h) and Section 16a-1(b) of the Exchange Act, respectively) with respect to such securities, other
than by will or by the laws of descent and distribution, and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, such Award may only be transferred (i) by will,
(ii) by the laws of descent and distribution, or (iii) as permitted by Rule 701 of the Securities Act of 1933, as amended. 
 13. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 
 (a) Adjustments. In the
event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, will adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award; provided, however, that
the Administrator will make such adjustments to an Award required by Section 25102(o) of the California Corporations Code to the extent the Company is relying upon the exemption afforded thereby with respect to the Award. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify
each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action. 

(c) Merger or Change in Control. In the event of a merger or Change in Control, each outstanding Award will be treated as the
Administrator determines without a Participant’s consent, including, without limitation, that (i) Awards will be assumed, or substantially equivalent Awards will be substituted, by the acquiring or succeeding corporation (or an affiliate
thereof) with appropriate adjustments as to the number and kind of shares and prices; (ii) upon written notice to a Participant, that the Participant’s Awards will terminate immediately prior to the consummation of such merger or Change in
Control; (iii) outstanding Awards will vest and become exercisable, realizable, or payable, or restrictions applicable to an Award will lapse, in whole or in part prior to or upon consummation of such merger or Change in Control, and, to the
extent the Administrator determines, terminate upon the effectiveness of such merger of Change in Control; (iv) (A) the termination of an Award in exchange for an amount of cash and/or property, if any, equal to the amount that would have
been attained upon the exercise of such Award or realization of the Participant’s rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the
Administrator determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment), or (B) the
replacement of such Award with other rights or property selected by the Administrator in its sole discretion; or (v) any combination of the foregoing. In taking any of the actions permitted under this subsection

  

 13 

 
13(c), the Administrator will not be obligated to treat all Awards, all Awards held by a Participant, or all Awards of the same type, similarly. 
 In the event that the successor corporation does not assume or substitute for the Award (or portion thereof), the Participant will fully
vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted
Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met.
In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a merger or Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right
will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 
 For the purposes of this subsection 13(c), an Award will be considered assumed if, following the merger or Change in Control, the Award
confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control
by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided,
however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the
consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal
in fair market value to the per share consideration received by holders of Common Stock in the merger or Change in Control. 
 Notwithstanding anything in this Section 13(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies
any of such performance goals without the Participant’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to
invalidate an otherwise valid Award assumption. 
 Notwithstanding anything in this Section 13(c) to the contrary, if a
payment under an Award Agreement is subject to Code Section 409A and if the change in control definition contained in the Award Agreement does not comply with the definition of “change of control” for purposes of a distribution under
Code Section 409A, then any payment of an amount that is otherwise accelerated under this Section will be delayed until the earliest time that such payment would be permissible under Code Section 409A without triggering any penalties
applicable under Code Section 409A. 
  

 14 

 14. Tax Withholding. 
 (a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof), the Company
will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to
be withheld with respect to such Award (or exercise thereof). 
 (b) Withholding Arrangements. The Administrator, in its
sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (i) paying cash, (ii) electing to have
the Company withhold otherwise deliverable Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, (iii) delivering to the Company already-owned Shares having a Fair Market Value equal to the statutory
amount required to be withheld, provided the delivery of such Shares will not result in any adverse accounting consequences, as the Administrator determines in its sole discretion, or (iv) selling a sufficient number of Shares otherwise
deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld. The amount of the withholding requirement will be deemed
to include any amount which the Administrator agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum federal, state or local marginal income tax rates applicable to the Participant with
respect to the Award on the date that the amount of tax to be withheld is to be determined. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 
 15. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to
continuing the Participant’s relationship as a Service Provider with the Company, nor will they interfere in any way with the Participant’s right or the Company’s right to terminate such relationship at any time, with or without
cause, to the extent permitted by Applicable Laws. 
 16. Date of Grant. The date of grant of an Award will be, for all
purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time
after the date of such grant. 
 17. Term of Plan. Subject to Section 21 of the Plan, the Plan will become effective
upon its adoption by the Board. Unless sooner terminated under Section 18, it will continue in effect for a term of ten (10) years from the later of (a) the effective date of the Plan, or (b) the earlier of the most recent Board
or stockholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 18. Amendment and
Termination of the Plan. 
  

 15 

 (a) Amendment and Termination. The Board may at any time amend, alter, suspend or
terminate the Plan. 
 (b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to
the extent necessary and desirable to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No
amendment, alteration, suspension or termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant
and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 
 19. Conditions Upon Issuance of Shares. 
 (a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws
and will be further subject to the approval of counsel for the Company with respect to such compliance. 
 (b) Investment
Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without
any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. 
 20. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained. 
 21. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months
after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 
 22. Information to Participants. Beginning on the date that the aggregate number of Participants under this Plan is five hundred (500) or more and until such time as the Company becomes
subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or is no longer relying on the exemption provided by Rule 12h-1(f)(1) under the Exchange Act, the Company will provide to each Participant the information
described in Rule 701 paragraphs (e)(3), (4), and (5) of Rule 701 under the Securities Act of 1933, as amended, not less frequently than every six (6) months with the financial statements being not more than 180 days old and with such
information provided either by physical or electronic delivery to the Participants or by written notice to the Participants of the availability of the information on an Internet site that may

  

 16 

 
be password-protected and of any password needed to access the information. The Company may request that Participants agree to keep the information to be provided pursuant to this section
confidential. If a Participant does not agree to keep the information to be provided pursuant to this section confidential, then the Company will not be required to provide the information.

	II.	AGREEMENT 

 1.
Grant of Option. The Administrator of the Company hereby grants to the Participant named in the Notice of Stock Option Grant in Part I of this Agreement (“Participant”), an option (the “Option”) to purchase
the number of Shares set forth in the Notice of Stock Option Grant, at the exercise price per Share set forth in the Notice of Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify
as an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”).
Further, if for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the
Administrator, the Company or any Parent or Subsidiary or any of their respective employees or directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 2. Definitions. As used herein, the following definitions shall apply: 
 (a) “FEMA” means the Foreign Exchange Management Act, 1999 of India, the rules and regulations notified thereunder and any
amendments thereto. The restrictions under FEMA, as referred to in this Option Agreement and as existing on the effective date of this Option Agreement, shall be read to include the amendments made to FEMA subsequent to the effective date of this
Option Agreement and will be deemed to have always included such amendments. 
  

 19 

 (b) “Indian Subsidiary” for the purpose of this Option Agreement, means [if
subsidiary does not yet exist a subsidiary incorporated in India for so long as the holding-subsidiary relationship exists between the Company and such subsidiary
] [if subsidiary exists [name of subsidiary] for so long as the holding-subsidiary relationship exists
between the Company and [name of subsidiary] as per the provisions of Section 4 of the Indian Companies Act, 1956. 
 3. Exercise of Option. 
 (a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Stock Option Grant and with the applicable provisions of the
Plan and this Option Agreement. 
 (b) Method of Exercise. This Option shall be exercisable by delivery of an exercise
notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall state the election to exercise the Option, the number of Shares
with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares,
together with any applicable tax withholding. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price, together with any applicable tax withholding.

 No shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable
Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Participant on the date on which the Option is exercised with respect to such Shares. 
 4. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended,
at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B. 
 5. Lock-Up Period. Participant hereby agrees that Participant shall not offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other
securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by
Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and eighty (180) days following the
effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other
distribution of research reports and (ii) analyst recommendations and

  

 20 

 
opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto). 
 Participant agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are
consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Participant shall provide,
within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed
under the Securities Act. The obligations described in this Section 5 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration
relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to
the foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this Section 5.

 6. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination
thereof, at the election of the Participant: 
 (a) cash; 
 (b) check; 
 (c)
consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of other Shares which (i) shall be valued at its Fair Market Value on the date of exercise, and (ii) must be owned free and clear of any liens, claims, encumbrances or security interests, if accepting such Shares, in
the sole discretion of the Administrator, shall not result in any adverse accounting consequences to the Company. 
 7.
Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for
such shares would constitute a violation of any Applicable Law. 
 8. Non-Transferability of Option. This Option may not
be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of Participant. 
  

 21 

 9. Term of Option. This Option may be exercised only within the term set out in the
Notice of Stock Option Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 
 10. Tax Obligations. 
 (a) Tax Withholding. Participant agrees to make appropriate arrangements with the
Company (or the Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and
agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant
to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, or (ii) the date one (1) year after the date of exercise, Participant shall immediately notify the Company in writing of such disposition.
Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation income recognized by Participant. 
 (c) Indian Fringe Benefit Tax. Except as otherwise determined by the Administrator, Participant agrees to reimburse or pay the Company (or its Indian Subsidiary, as directed by the Indian
Subsidiary) in full, any liability that the Company or its Indian Subsidiary incurs towards any Indian fringe benefit tax (“FBT”), social tax, or other Indian tax paid or payable in respect of the grant, vesting, delivery, or
exercise of the Option or the underlying Shares, within the time and in the manner prescribed by the Company or its Indian Subsidiary. The Administrator may in its sole discretion determine whether the FBT with respect to the Option or its
underlying Shares will be paid (i) by selling a portion of vested Shares, (ii) by collecting direct payment from the Participant to the Company, (iii) by withholding a number of Shares upon exercise with a Fair Market Value equal to
the FBT liability, (iv) by withholding all applicable taxes legally payable by Participant from the Participant’s wages or other cash compensation paid to Participant by the Company (and/or the Parent or Subsidiary employing or retaining
Participant), (v) by some other method, or (vi) by some combination thereof. Participant agrees to execute any additional documents requested by the Company or its Indian Subsidiary for the reimbursement of such taxes to the Company.

 The Participant grants to the Company and its Indian Subsidiary the irrevocable authority, as agents of Participant and on
his or her behalf, to sell, retain or procure the sale of sufficient Shares subject to the Option so that the net proceeds receivable by the Company or its Indian Subsidiary are as far as possible equal to but not less than the amount of any tax the
Participant is liable for (including FBT reimbursement obligations pursuant to the preceding paragraph) and the Company or its Indian Subsidiary shall remit any balance to Participant. 
 Participant acknowledges and agrees that the Company may refuse to deliver Shares upon exercise of the Option if Participant has not made
appropriate arrangements with the Company or its Indian Subsidiary to satisfy the FBT. 
  

 22 

 (d) Code Section 409A. Under Code Section 409A, an Option that vests after
December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the Internal Revenue Service (the
“IRS”) to be less than the Fair Market Value of a Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount option” may result in
(i) income recognition by Participant prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The “discount option” may also
result in additional state income, penalty and interest tax to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share exercise price of this Option equals or exceeds the
Fair Market Value of a Share on the date of grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less than the Fair Market Value of a Share on the date of
grant, Participant shall be solely responsible for Participant’s costs related to such a determination. 
 11.
Acknowledgements. 
 (a) Participant acknowledges receipt of a copy of the Plan and represents that he or she is familiar
with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan (including any applicable appendixes or sub plans thereunder) and this Option in their
entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations
of the Administrator upon any questions arising under the Plan or this Option. Participant further agrees to notify the Company upon any change in the residence address indicated below. 
 (b) The Company (and not the Participant’s employer) is granting the Option. The Company will administer the Plan from outside
Participant’s country of residence and that United States of America law along with FEMA and other applicable Indian laws will govern all Options granted under the Plan. 
 (c) Participant acknowledges that Participant, being a resident of India, is currently limited to investing an aggregate of no more than
$200,000 USD per fiscal year in offshore companies, if the exercise occurs after Participant ceases to be a Service Provider. The Company is considered to be an offshore company. Participant acknowledges it is Participant’s responsibility to
comply with this restriction (as it may be in force at the time of exercise of the Option) and to coordinate any investment in the Company through exercise of the Option with other investments made by Participant in offshore companies during a
fiscal year. 
 (d) That benefits and rights provided under the Plan are wholly discretionary and, although provided by the
Company, do not constitute regular or periodic payments. The benefits and rights provided under the Plan are not to be considered part of Participant’s salary or compensation for purposes of calculating any severance, resignation, redundancy or
other end of service payments, vacation, bonuses, long-term service awards, indemnification, pension or retirement benefits, or any other payments, benefits or rights of any kind, statutory or otherwise.

  

 23 

 
Participant waives any and all rights to compensation or damages as a result of the termination of employment with the Company for any reason whatsoever insofar as those rights result or may
result from: 
 (i) the loss or diminution in value of such rights under the Plan, or 
 (ii) Participant ceases to have any rights under, or ceases to be entitled to any rights under the Plan as a result of such termination.

 (e) The grant of the Option, and any future grant of Options under the Plan is entirely voluntary, and at the complete
discretion of the Company. Neither the grant of the Option nor any future grant of an Option by the Company will be deemed to create any obligation to grant any further Options, whether or not such a reservation is explicitly stated at the time of
such a grant. The grant of the Option also does not constitute a customary concession or privilege, or create a vested right in the Participant to require the grant of Options or other awards to be made each year. The Company has the right, at any
time to amend, suspend or terminate the Plan without the consent of and without notice to the Participant. 
 (f) The Plan will
not be deemed to constitute, and will not be construed by Participant to constitute, part of the terms and conditions of employment, and that the Company will not incur any liability of any kind to Participant as a result of any change or amendment,
or any cancellation, of the Plan at any time. 
 (g) Participation in the Plan will not be deemed to constitute, and will not be
deemed by Participant to constitute, an employment or labor relationship of any kind with the Company. 
 (h) By entering into
this Option Agreement, and as a condition of the grant of the Option, Participant consents to the collection, use, and transfer of personal data as described in this subsection to the full extent permitted by and in full compliance with applicable
laws. 
 (i) Participant understands that the Company and its Subsidiaries hold certain personal information about the
Participant, including, but not limited to, name, home address and telephone number, date of birth, social insurance number, salary, nationality, job title, any Shares or directorships held in the Company, details of all Options or other entitlement
to Shares awarded, canceled, exercised, vested, unvested, or outstanding in Participant’s favor, for the purpose of managing and administering the Plan (“Data”). 
 (ii) Participant further understands that the Company and/or its Subsidiaries will transfer Data among themselves as necessary for the
purposes of implementation, administration, and management of Participant’s participation in the Plan, and that the Company and/or its Subsidiary may each further transfer Data to any third parties assisting the Company in the implementation,
administration, and management of the Plan (“Data Recipients”). 
  

 24 

 (iii) Participant understands that these Data Recipients may be located in
Participant’s country of residence or elsewhere, such as the United States. Participant authorizes the Data Recipients to receive, possess, use, retain, and transfer Data in electronic or other form, for the purposes of implementing,
administering, and managing Participant’s participation in the Plan, including any transfer of such Data, as may be required for the administration of the Plan and/or the subsequent holding of Shares on Participant’s behalf, to a broker or
third party with whom the Shares acquired on exercise may be deposited. 
 (iv) Participant understands that Participant may,
at any time, review the Data, request that any necessary amendments be made to it, or withdraw Participant’s consent herein in writing by contacting the Company. Participant further understands that withdrawing consent may affect
Participant’s ability to participate in the Plan. 
 (i) Participant has received the terms and conditions of this Option
Agreement and any other related communications, and Participant consents to having received these documents in English. 
 12.
Entire Agreement; Governing Law. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all
contemporaneous or prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company
and Participant. This Agreement is governed by the internal substantive laws but not the choice of law rules of California. 
 13. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE
PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED
HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH
PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

 EXHIBIT A 
 2008 EQUITY INCENTIVE PLAN 
 EXERCISE NOTICE 

 Kazeon Systems, Inc. 
 1161 San
Antonio Road 
 Mountain View, CA 94043 
 Attention: Chief Financial Officer 
 1. Exercise of Option. Effective as of today,
                    ,             , the undersigned
(“Participant”) hereby elects to exercise Participant’s option (the “Option”) to purchase
                     shares of the Common Stock (the “Shares”) of Kazeon Systems, Inc. (the “Company”) under
and pursuant to the 2008 Equity Incentive Plan (the “Plan”) and the Stock Option Agreement dated                     ,
            , (the “Option Agreement”). 
 2. Delivery of Payment. Participant herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection with the exercise of the Option, as
well as reimbursement for fringe benefits tax payable by the Company or its Indian Subsidiary under the Income Tax Act, 1961 applicable to the exercise of the Option. 
 3. Representations of Participant. Participant acknowledges that Participant has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms
and conditions. 
 4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the
exercise of the Option. The Shares shall be issued to Participant as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is
prior to the date of issuance except as provided in Section 13 of the Plan. 
 5. Company’s Right of First
Refusal. Before any Shares held by Participant or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or
its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section 5 (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the
“Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the
number of Shares to be transferred to each Proposed

  

 27 

 
Transferee; and (iv) the bona fide cash price or other compensation for which the Holder proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer
the Shares at the Offered Price to the Company or its assignee(s). 
 (b) Exercise of Right of First Refusal. At any time
within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of
the Proposed Transferees, at the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase
Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash
equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (d) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in
the case of repurchase by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are
not purchased by the Company and/or its assignee(s) as provided in this Section 5, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale
or other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees
in writing that the provisions of this Section 5 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new
Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer
of any or all of the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the Participant’s immediate family or a trust for the benefit of the Participant’s immediate family shall be
exempt from the provisions of this Section 5. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall
receive and hold the Shares so transferred subject to the provisions of this Section 5, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 5. 
 (g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of
(i) the first sale of Common Stock of the Company

  

 28 

 
to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 
 6. Tax Consultation. Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s
purchase or disposition of the Shares. Participant represents that Participant has consulted with any tax consultants Participant deems advisable in connection with the purchase or disposition of the Shares and that Participant is not relying on the
Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED,
SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST
REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT
OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
RESTRICTIONS ON TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD
OR OTHERWISE DISPOSED OF BY THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop

  

 29 

 
transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

 (c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been
sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall
have been so transferred. 
 8. Successors and Assigns. The Company may assign any of its rights under this Exercise
Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon
Participant and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute
regarding the interpretation of this Exercise Notice shall be submitted by Participant or by the Company forthwith to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the
Administrator shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is
governed by the internal substantive laws, but not the choice of law rules, of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise Notice
shall continue in full force and effect. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein
by reference. This Exercise Notice, the Plan, the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior
undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant.

 In connection with the purchase of the above-listed Securities, the undersigned
Participant represents to the Company the following: 
 (a) Participant is aware of the Company’s business affairs and
financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only
and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and
have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this
connection, Participant understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in
the future. Participant further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and
understands that the Company is under no obligation to register the Securities. Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 
 (c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public

  

 32 

 
offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to Participant, the exercise shall
be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period
as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144, including in the case of affiliates (1) the availability of
certain public information about the Company, (2) the amount of Securities being sold during any three (3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s
transaction”, transactions directly with a “market maker” or “riskless principal transactions” (as those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if
applicable. 
 In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the
Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public information about the Company; (ii) the resale to occur more than a specified period
after the purchase and full payment (within the meaning of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3) and (4) of the
paragraph immediately above. 
 (d) Participant further understands that in the event all of the applicable requirements of Rule
701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the
Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 shall have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Participant understands that no assurances can
be given that any such other registration exemption shall be available in such event.

Option may be subject to earlier termination as provided in Section 13(c) of the Plan. 
  

	II.	AGREEMENT 

 1.
Grant of Option. The Administrator of the Company hereby grants to the Participant named in the Notice of Stock Option Grant in Part I of this Agreement (“Participant”), an option (the “Option”) to purchase the number of
Shares set forth in the Notice of Stock Option Grant, at the exercise price per Share set forth in the Notice of Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein
by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an
Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further, if
for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator, the
Company or any Parent or Subsidiary or any of their respective employees or directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 2. Exercise of Option. 
 (a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Stock Option Grant and with the applicable provisions of the
Plan and this Option Agreement. 
 (b) Method of Exercise. This Option shall be exercisable by delivery of an exercise
notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall state the election to exercise the Option, the number of Shares with
respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares, together
with any applicable tax withholding. This Option shall be deemed to

  

 35 

 
be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price, together with any applicable tax withholding. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws. Assuming
such compliance, for income tax purposes the Shares shall be considered transferred to Participant on the date on which the Option is exercised with respect to such Shares. 
 3. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended,
at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B. 
 4. Lock-Up Period. Participant hereby agrees that Participant shall not offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other
securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by
Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and eighty (180) days following the
effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other
distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto).

 Participant agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the
underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company,
Participant shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a
registration statement filed under the Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in
the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or
other securities) subject to the foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by
this Section 4. 
  

 36 

 5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the
following, or a combination thereof, at the election of the Participant: 
 (a) cash; 
 (b) check; 
 (c)
consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of other Shares which (i) shall be valued at its Fair Market Value on the date of exercise, and (ii) must be owned free and clear of any liens, claims, encumbrances or security interests, if accepting such Shares, in
the sole discretion of the Administrator, shall not result in any adverse accounting consequences to the Company. 
 6.
Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for
such shares would constitute a violation of any Applicable Law. 
 7. Non-Transferability of Option. This Option may not
be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of Participant. 
 8. Term of Option. This Option may be
exercised only within the term set out in the Notice of Stock Option Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 
 9. Tax Obligations. 
 (a) Tax Withholding. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Federal,
state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding
amounts are not delivered at the time of exercise. 
 (b) Notice of Disqualifying Disposition of ISO Shares. If the
Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, or (ii) the
date one (1) year after the date of exercise, Participant shall immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation
income recognized by Participant. 
  

 37 

 (c) Code Section 409A. Under Code Section 409A, an Option that vests after
December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the Internal Revenue Service (the “IRS”)
to be less than the Fair Market Value of a Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount option” may result in (i) income recognition by
Participant prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The “discount option” may also result in additional state income,
penalty and interest tax to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share exercise price of this Option equals or exceeds the Fair Market Value of a Share on the
date of grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less than the Fair Market Value of a Share on the date of grant, Participant shall be solely
responsible for Participant’s costs related to such a determination. 
 10. Entire Agreement; Governing Law. The
Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the
Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. This Agreement is governed by the internal
substantive laws but not the choice of law rules of California. 
 11. No Guarantee of Continued Service. PARTICIPANT
ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH
THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN
EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY
EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

 2008 EQUITY INCENTIVE PLAN 
 EXERCISE NOTICE 

 Kazeon Systems, Inc. 
 1161 San
Antonio Road 
 Mountain View, CA 94043 
 Attention: Chief Financial Officer 
 1. Exercise of Option. Effective as of today,
                    ,             , the undersigned
(“Participant”) hereby elects to exercise Participant’s option (the “Option”) to purchase                      shares
of the Common Stock (the “Shares”) of Kazeon Systems, Inc. (the “Company”) under and pursuant to the 2008 Equity Incentive Plan (the “Plan”) and the Stock Option Agreement dated
                    ,             , (the “Option Agreement”).

 2. Delivery of Payment. Participant herewith delivers to the Company the full purchase price of the Shares, as set
forth in the Option Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 
 3.
Representations of Participant. Participant acknowledges that Participant has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 
 4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a
duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the exercise of the Option. The Shares shall
be issued to Participant as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as
provided in Section 13 of the Plan. 
 5. Company’s Right of First Refusal. Before any Shares held by
Participant or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this Section 5 (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares;
(ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other compensation for
which the Holder

  

 40 

 
proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 
 (b) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its
assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below. 
 (c) Purchase Price. The purchase price (“Purchase Price”) for the Shares
purchased by the Company or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board
of Directors of the Company in good faith. 
 (d) Payment. Payment of the Purchase Price shall be made, at the option of
the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof
within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e)
Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 5, then the Holder may sell
or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that
any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 5 shall continue to apply to the Shares in the hands of such
Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First
Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family
Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer of any or all of the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the
Participant’s immediate family or a trust for the benefit of the Participant’s immediate family shall be exempt from the provisions of this Section 5. “Immediate Family” as used herein shall mean spouse, lineal descendant or
antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section 5, and there shall be no further transfer of such Shares
except in accordance with the terms of this Section 5. 
 (g) Termination of Right of First Refusal. The Right of
First Refusal shall terminate as to any Shares upon the earlier of (i) the first sale of Common Stock of the Company

  

 41 

 
to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 
 6. Tax Consultation. Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s
purchase or disposition of the Shares. Participant represents that Participant has consulted with any tax consultants Participant deems advisable in connection with the purchase or disposition of the Shares and that Participant is not relying on the
Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED,
SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST
REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT
OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
RESTRICTIONS ON TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD
OR OTHERWISE DISPOSED OF BY THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop

  

 42 

 
transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

 (c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been
sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall
have been so transferred. 
 8. Successors and Assigns. The Company may assign any of its rights under this Exercise
Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon
Participant and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute
regarding the interpretation of this Exercise Notice shall be submitted by Participant or by the Company forthwith to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the
Administrator shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is
governed by the internal substantive laws, but not the choice of law rules, of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise Notice
shall continue in full force and effect. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein
by reference. This Exercise Notice, the Plan, the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior
undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant.

 In connection with the purchase of the above-listed Securities, the undersigned
Participant represents to the Company the following: 
 (a) Participant is aware of the Company’s business affairs and
financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only
and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and
have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this
connection, Participant understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in
the future. Participant further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and
understands that the Company is under no obligation to register the Securities. Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 
 (c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public

  

 45 

 
offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to Participant, the exercise shall
be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period
as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144, including in the case of affiliates (1) the availability of
certain public information about the Company, (2) the amount of Securities being sold during any three (3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s
transaction”, transactions directly with a “market maker” or “riskless principal transactions” (as those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if
applicable. 
 In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the
Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public information about the Company; (ii) the resale to occur more than a specified period
after the purchase and full payment (within the meaning of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3) and (4) of the
paragraph immediately above. 
 (d) Participant further understands that in the event all of the applicable requirements of Rule
701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the
Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 shall have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Participant understands that no assurances can
be given that any such other registration exemption shall be available in such event.

 Termination Period: 
 This Option shall be exercisable for three (3) months after Participant ceases to be a Service Provider, unless such termination is due to Participant’s death or Disability, in which case this
Option shall be exercisable for twelve (12) months after Participant ceases to be a Service Provider. Notwithstanding the foregoing sentence, in no event may this Option be exercised after the Term/Expiration Date as provided above and this
Option may be subject to earlier termination as provided in Section 13(c) of the Plan. 
  

	II.	AGREEMENT 

 1.
Grant of Option. The Administrator of the Company hereby grants to the Participant named in the Notice of Stock Option Grant in Part I of this Agreement (“Participant”), an option (the “Option”) to purchase the number of
Shares set forth in the Notice of Stock Option Grant, at the exercise price per Share set forth in the Notice of Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein
by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an
Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further, if
for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator, the
Company or any Parent or Subsidiary or any of their respective employees or directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 2. Exercise of Option. This Option shall be exercisable during its term in accordance with the provisions of Section 6 of the
Plan as follows: 
 (a) Right to Exercise. 
 (i) Subject to subsections 2(a)(ii) and 2(a)(iii) below, this Option shall be exercisable cumulatively according to the vesting schedule
set forth in the Notice of Stock Option Grant. Alternatively, at the election of Participant, this Option may be exercised in whole or in part at any time as to Shares that have not yet vested. Vested Shares shall not be subject to the
Company’s repurchase right (as set forth in the Restricted Stock Purchase Agreement, attached hereto as Exhibit C-1). 
  

 48 

 (ii) As a condition to exercising this Option for unvested Shares, Participant shall
execute the Restricted Stock Purchase Agreement. 
 (iii) This Option may not be exercised for a fraction of a Share.

 (b) Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as
Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall state the election to exercise the Option, the number of Shares with respect to which the Option is
being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares, together with any applicable tax
withholding. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price, together with any applicable tax withholding. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws. Assuming
such compliance, for income tax purposes the Shares shall be considered transferred to Participant on the date on which the Option is exercised with respect to such Shares. 
 3. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended,
at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B. 
 4. Lock-Up Period. Participant hereby agrees that Participant shall not offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other
securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by
Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and eighty (180) days following the
effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other
distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto).

 Participant agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the
underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company,
Participant shall provide, within ten (10) days of such request, such information as may be

  

 49 

 
required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the
Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating
solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the
foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this Section 4. 
 5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the
election of the Participant: 
 (a) cash; 
 (b) check; 
 (c) consideration received by the Company under a formal cashless
exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of other Shares which (i) shall be
valued at its Fair Market Value on the date of exercise, and (ii) must be owned free and clear of any liens, claims, encumbrances or security interests, if accepting such Shares, in the sole discretion of the Administrator, shall not result in
any adverse accounting consequences to the Company. 
 6. Restrictions on Exercise. This Option may not be exercised
until such time as the Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law.

 7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the
laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of
Participant. 
 8. Term of Option. This Option may be exercised only within the term set out in the Notice of Stock
Option Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 
 9. Tax
Obligations. 
 (a) Tax Withholding. Participant agrees to make appropriate arrangements with the Company (or the
Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the

  

 50 

 
Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein is an ISO, and if Participant
sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, or (ii) the date one (1) year after the date of exercise, Participant
shall immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation income recognized by Participant. 
 (c) Code Section 409 A. Under Code Section 409A, an Option that vests after December 31, 2004 (or that vested on or
prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the Internal Revenue Service (the “IRS”) to be less than the Fair Market Value of a
Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount option” may result in (i) income recognition by Participant prior to the exercise of the
Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The “discount option” may also result in additional state income, penalty and interest tax to the
Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share exercise price of this Option equals or exceeds the Fair Market Value of a Share on the date of grant in a later
examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less than the Fair Market Value of a Share on the date of grant, Participant shall be solely responsible for
Participant’s costs related to such a determination. 
 10. Entire Agreement; Governing Law. The Plan is
incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and
Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. This Agreement is governed by the internal substantive
laws but not the choice of law rules of California. 
 11. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES
AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF
BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR
IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR
RETAINING PARTICIPANT) TO TERMINATE

  

 51 

 
PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 (Signature page follows)

 Participant acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the
terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to
executing this Option and fully understands all provisions of the Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this

 2008 EQUITY INCENTIVE PLAN 
 EXERCISE NOTICE 

 Kazeon Systems, Inc. 
 1161 San
Antonio Road 
 Mountain View, CA 94043 
 Attention: Chief Financial Officer 
 1. Exercise of Option. Effective as of today,
                        ,             , the undersigned
(“Participant”) hereby elects to exercise Participant’s option (the “Option”) to purchase                  shares of the Common
Stock (the “Shares”) of Kazeon Systems, Inc. (the “Company”) under and pursuant to the 2008 Equity Incentive Plan (the “Plan”) and the Stock Option Agreement dated
                        ,             , (the
“Option Agreement”). 
 2. Delivery of Payment. Participant herewith delivers to the Company the full purchase
price of the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 
 3. Representations of Participant. Participant acknowledges that Participant has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms
and conditions. 
 4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the
exercise of the Option. The Shares shall be issued to Participant as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is
prior to the date of issuance except as provided in Section 13 of the Plan. 
 5. Company’s Right of First
Refusal. Before any Shares held by Participant or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its
assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section 5 (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”)
stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred
to each Proposed Transferee; and (iv) the bona fide cash price or other compensation for which the Holder

  

 54 

 
proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 
 (b) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its
assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below. 
 (c) Purchase Price. The purchase price (“Purchase Price”) for the Shares
purchased by the Company or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board
of Directors of the Company in good faith. 
 (d) Payment. Payment of the Purchase Price shall be made, at the option of
the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof
within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e)
Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 5, then the Holder may sell
or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that any
such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 5 shall continue to apply to the Shares in the hands of such
Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First
Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family
Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer of any or all of the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the
Participant’s immediate family or a trust for the benefit of the Participant’s immediate family shall be exempt from the provisions of this Section 5. “Immediate Family” as used herein shall mean spouse, lineal descendant or
antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section 5, and there shall be no further transfer of such Shares
except in accordance with the terms of this Section 5. 
 (g) Termination of Right of First Refusal. The Right of
First Refusal shall terminate as to any Shares upon the earlier of (i) the first sale of Common Stock of the Company

  

 55 

 
to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 
 6. Tax Consultation. Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s
purchase or disposition of the Shares. Participant represents that Participant has consulted with any tax consultants Participant deems advisable in connection with the purchase or disposition of the Shares and that Participant is not relying on the
Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED,
SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST
REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT
OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
RESTRICTIONS ON TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD
OR OTHERWISE DISPOSED OF BY THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop

  

 56 

 
transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

 (c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been
sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall
have been so transferred. 
 8. Successors and Assigns. The Company may assign any of its rights under this Exercise
Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon
Participant and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute
regarding the interpretation of this Exercise Notice shall be submitted by Participant or by the Company forthwith to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the
Administrator shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is
governed by the internal substantive laws, but not the choice of law rules, of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise Notice
shall continue in full force and effect. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein
by reference. This Exercise Notice, the Plan, the Restricted Stock Purchase Agreement, the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by
the Company and Participant.

 In connection with the purchase of the above-listed Securities, the undersigned Participant
represents to the Company the following: 
 (a) Participant is aware of the Company’s business affairs and financial
condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not
with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and
have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this
connection, Participant understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in
the future. Participant further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and
understands that the Company is under no obligation to register the Securities. Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 
 (c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public

  

 59 

 
offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to Participant, the exercise shall
be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period
as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144, including in the case of affiliates (1) the availability of
certain public information about the Company, (2) the amount of Securities being sold during any three (3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s
transaction”, transactions directly with a “market maker” or “riskless principal transactions” (as those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if
applicable. 
 In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the
Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public information about the Company; (ii) the resale to occur more than a specified period
after the purchase and full payment (within the meaning of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3) and (4) of the
paragraph immediately above. 
 (d) Participant further understands that in the event all of the applicable requirements of Rule
701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the
Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 shall have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Participant understands that no assurances can
be given that any such other registration exemption shall be available in such event.

 KAZEON SYSTEMS, INC. 
 2008 EQUITY INCENTIVE PLAN

 RESTRICTED STOCK PURCHASE AGREEMENT 
 THIS RESTRICTED STOCK AWARD AGREEMENT (the “Agreement”) is made between
                                        
(the “Purchaser”) and Kazeon Systems, Inc. (the “Company”) or its assignees of rights hereunder as of
                    ,              . 
 Unless otherwise defined herein, the terms defined in the 2008 Equity Incentive Plan shall have the same defined meanings in this Agreement.

 RECITALS 
 A. Pursuant to the exercise of the option (grant number                  ) granted to Purchaser under the Plan and
pursuant to the Stock Option Agreement (the “Option Agreement”) dated
                    ,              by and between the Company and
Purchaser with respect to such grant (the “Option”), which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase
                 of those shares of Common Stock which have not become vested under the vesting schedule set forth in the Option Agreement (“Unvested
Shares”). The Unvested Shares and the shares subject to the Option Agreement, which have become vested are sometimes collectively referred to herein as the “Shares.” 
 B. As required by the Option Agreement, as a condition to Purchaser’s election to exercise the option, Purchaser must execute this
Agreement, which sets forth the rights and obligations of the parties with respect to Shares acquired upon exercise of the Option. 
 1. Repurchase Option. 
 (a) If Purchaser’s status as a Service Provider is terminated for any reason,
including for death and Disability, the Company shall have the right and option for ninety (90) days from such date to purchase from Purchaser, or Purchaser’s personal representative, as the case may be, all of the Purchaser’s
Unvested Shares as of the date of such termination at the price paid by the Purchaser for such Shares (the “Repurchase Option”). 
 (b) Upon the occurrence of such termination, the Company may exercise its Repurchase Option by delivering personally or by registered mail, to Purchaser (or his or her transferee or legal representative,
as the case may be) with a copy to the escrow agent described in Section 2 below, a notice in writing indicating the Company’s intention to exercise the Repurchase Option AND, at the Company’s option, (i) by delivering to the
Purchaser (or the Purchaser’s transferee or legal representative) a check in the amount of the aggregate repurchase price, or (ii) by the Company canceling an amount of the Purchaser’s indebtedness to the

  

 61 

 
Company equal to the aggregate repurchase price, or (iii) by a combination of (i) and (ii) so that the combined payment and cancellation of indebtedness equals such aggregate
repurchase price. Upon delivery of such notice and payment of the aggregate repurchase price in any of the ways described above, the Company shall become the legal and beneficial owner of the Unvested Shares being repurchased and the rights and
interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Unvested Shares being repurchased by the Company. 
 (c) Whenever the Company shall have the right to repurchase Unvested Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or stockholders of the Company or other persons or organizations to exercise all or a part of the Company’s Repurchase Option under this Agreement and purchase all or a part of such Unvested Shares. 
 (d) If the Company does not elect to exercise the Repurchase Option conferred above by giving the requisite notice within ninety
(90) days following the termination, the Repurchase Option shall terminate. 
 (e) The Repurchase Option shall terminate in
accordance with the vesting schedule contained in Purchaser’s Option Agreement. 
 2. Transferability of the Shares;
Escrow. 
 (a) Purchaser hereby authorizes and directs the Secretary of the Company, or such other person designated by the
Company, to transfer the Unvested Shares as to which the Repurchase Option has been exercised from Purchaser to the Company. 
 (b) To insure the availability for delivery of Purchaser’s Unvested Shares upon repurchase by the Company pursuant to the Repurchase Option under Section 1, Purchaser hereby appoints the Secretary, or any other person designated
by the Company as escrow agent (the “Escrow Agent”), as its attorney-in-fact to sell, assign and transfer unto the Company, such Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall, upon
execution of this Agreement, deliver and deposit with the Escrow Agent, the share certificates representing the Unvested Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested Shares
and stock assignment shall be held by the Escrow Agent in escrow, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as Exhibit C-3 hereto, until the Company exercises its Repurchase Option, until such Unvested
Shares are vested, or until such time as this Agreement no longer is in effect. Upon vesting of the Unvested Shares, the Escrow Agent shall promptly deliver to the Purchaser the certificate or certificates representing such Shares in the Escrow
Agent’s possession belonging to the Purchaser, and the Escrow Agent shall be discharged of all further obligations hereunder; provided, however, that the Escrow Agent shall nevertheless retain such certificate or certificates as Escrow Agent if
so required pursuant to other restrictions imposed pursuant to this Agreement. 
  

 62 

 (c) Neither the Company nor the Escrow Agent shall be liable for any act it may do or omit
to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment. 
 (d)
Transfer or sale of the Shares is subject to restrictions on transfer imposed by any applicable state and federal securities laws. Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the
Purchaser with respect to any Unvested Shares purchased by Purchaser and shall acknowledge the same by signing a copy of this Agreement. 
 3. Ownership, Voting Rights, Duties. This Agreement shall not affect in any way the ownership, voting rights or other rights or duties of Purchaser, except as specifically provided herein.

 4. Legends. The share certificate evidencing the Shares issued hereunder shall be endorsed with the following legend
(in addition to any legend required under applicable federal and state securities laws): 
 THE SHARES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 
 5. Adjustment for Stock Split. All references to the number of Shares and the purchase price of the Shares in this Agreement shall be
appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares, which may be made by the Company pursuant to Section 13 of the Plan after the date of this Agreement. 
 6. Notices. Notices required hereunder shall be given in person or by registered mail to the address of Purchaser shown on the
records of the Company, and to the Company at their respective principal executive offices. 
 7. Survival of Terms. This
Agreement shall apply to and bind Purchaser and the Company and their respective permitted assignees and transferees, heirs, legatees, executors, administrators and legal successors. 
 8. Section 83(b) Election. Purchaser hereby acknowledges that he or she has been informed that, with respect to the exercise of
an Option for Unvested Shares, an election (the “Election”) may be filed by the Purchaser with the Internal Revenue Service, within thirty (30) days of the purchase of the exercised Shares, electing pursuant to Section 83(b) of
the Code to be taxed currently on any difference between the purchase price of the exercised Shares and their Fair Market Value on the date of purchase. In the case of a Nonstatutory Stock Option, this will result in the recognition of taxable
income to the Purchaser on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at the time the Option is exercised over the purchase price for the exercised Shares. Absent such an Election, taxable

income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. In the case of an Incentive Stock Option, such an Election will
result in a recognition of income to the Purchaser for alternative minimum tax purposes on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at the time the option is exercised, over the purchase
price for the exercised Shares. Absent such an Election, alternative minimum taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. 
 This discussion is intended only as a summary of the general United States income tax laws that apply to exercising Options as to Shares
that have not yet vested and is accurate only as of the date this form Agreement was approved by the Board. The federal, state and local tax consequences to any particular taxpayer will depend upon his or her individual circumstances. Purchaser is
strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election under Section 83(b) of the Code. A form of Election under Section 83(b)
is attached hereto as Exhibit C-4 for reference. 
 PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER’S SOLE
RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER’S BEHALF. 
 9. Representations. Purchaser has reviewed with his or her own tax advisors the federal, state, local and foreign tax consequences of
this investment and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Purchaser understands that he or she (and not the
Company) shall be responsible for his or her own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 
 10. Entire Agreement; Governing Law. The Plan and Option Agreement are incorporated herein by reference. The Plan, the Option Agreement, the Exercise Notice, this Agreement, and the Investment
Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Purchaser with respect to the subject matter
hereof, and may not be modified adversely to the Purchaser’s interest except by means of a writing signed by the Company and Purchaser. This Agreement is governed by the internal substantive laws but not the choice of law rules of California.

 Purchaser represents that he or she has read this Agreement and is familiar with its terms and provisions. Purchaser hereby
agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under this Agreement.

 IN WITNESS WHEREOF, this Agreement is deemed made as of the date first set forth above.

 Dear
                                        :

 As Escrow Agent for both Kazeon Systems, Inc. (the “Company”), and the undersigned purchaser of stock of the
Company (the “Purchaser”), you are hereby authorized and directed to hold the documents delivered to you pursuant to the terms of that certain Restricted Stock Purchase Agreement (the “Agreement”) between the Company and the
undersigned, in accordance with the following instructions: 
 1. In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the “Company”) exercises the Company’s repurchase option set forth in the Agreement, the Company shall give to Purchaser and you a written notice specifying the number of shares of
stock to be purchased, the purchase price, and the time for a closing hereunder at the principal office of the Company. Purchaser and the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice. 
 2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares being transferred, and (c) to deliver the stock assignments, together with the certificate evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by cash, a check, or some combination thereof) for the number of shares of stock being purchased pursuant to the exercise of the Company’s repurchase option. 

3. Purchaser irrevocably authorizes the Company to deposit with you any certificates evidencing shares of stock to be held by you
hereunder and any additions and substitutions to said shares as defined in the Agreement. Purchaser does hereby irrevocably constitute and appoint you as Purchaser’s attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such securities negotiable and to complete any transaction herein contemplated, including but not limited to the filing with any applicable state blue sky authority of any required

 67 

 4. Upon written request of the Purchaser, but no more than once per calendar year, unless
the Company’s repurchase option has been exercised, you shall deliver to Purchaser a certificate or certificates representing so many shares of stock as are not then subject to the Company’s repurchase option. Within one hundred and twenty
(120) days after cessation of Purchaser’s continuous employment by or services to the Company, or any parent or subsidiary of the Company, you shall deliver to Purchaser a certificate or certificates representing the aggregate number of
shares held or issued pursuant to the Agreement and not purchased by the Company or its assignees pursuant to exercise of the Company’s repurchase option. 
 5. If at the time of termination of this escrow you should have in your possession any documents, securities, or other property belonging to Purchaser, you shall deliver all of the same to Purchaser and
shall be discharged of all further obligations hereunder. 
 6. Your duties hereunder may be altered, amended, modified or
revoked only by a writing signed by all of the parties hereto. 
 7. You shall be obligated only for the performance of such
duties as are specifically set forth herein and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed by you to be genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith, and any act done or omitted by you pursuant to the advice of your own attorneys shall be
conclusive evidence of such good faith. 
 8. You are hereby expressly authorized to disregard any and all warnings given by any
of the parties hereto or by any other person or corporation, excepting only orders or process of courts of law and are hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case you obey or comply with any
such order, judgment or decree, you shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified,
annulled, set aside, vacated or found to have been entered without jurisdiction. 
 9. You shall not be liable in any respect on
account of the identity, authorities or rights of the parties executing or delivering or purporting to execute or deliver the Agreement or any documents or papers deposited or called for hereunder. 
 10. You shall not be liable for the outlawing of any rights under the Statute of Limitations with respect to these Joint Escrow Instructions
or any documents deposited with you. 
 11. You shall be entitled to employ such legal counsel and other experts as you may deem
necessary properly to advise you in connection with your obligations hereunder, may rely upon the advice of such counsel, and may pay such counsel reasonable compensation therefor. 
  

 68 

 12. Your responsibilities as Escrow Agent hereunder shall terminate if you shall cease to be
an officer or agent of the Company or if you shall resign by written notice to each party. In the event of any such termination, the Company shall appoint a successor Escrow Agent. 
 13. If you reasonably require other or further instruments in connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments. 
 14. It is understood and agreed that should
any dispute arise with respect to the delivery and/or ownership or right of possession of the securities held by you hereunder, you are authorized and directed to retain in your possession without liability to anyone all or any part of said
securities until such disputes shall have been settled either by mutual written agreement of the parties concerned or by a final order, decree or judgment of a court of competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend any such proceedings. 
 15. Any notice
required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States Post Office, by registered or certified mail with postage and fees prepaid, addressed to each
of the other parties thereunto entitled at the following addresses or at such other addresses as a party may designate by ten (10) days’ advance written notice to each of the other parties hereto. 
 16. By signing these Joint Escrow Instructions, you become a party hereto only for the purpose of said Joint Escrow Instructions; you do not
become a party to the Agreement. 
 17. This instrument shall be binding upon and inure to the benefit of the parties hereto,
and their respective successors and permitted assigns. 
 18. These Joint Escrow Instructions shall be governed by the internal
substantive laws, but not the choice of law rules, of California.
