 By your signature and the signature of the Company’s representative below, you and the
Company agree that this option is granted under and governed by the terms and conditions of the Cyan, Inc. 2006 Stock Plan and the Stock Option Agreement, both of which are attached and made a part of this document. 

In addition, you agree and acknowledge that your rights to any Shares underlying the Option will be earned only as you provide services
to the Company over time, that the grant of the Option is not as consideration for services you rendered to the Company prior to your Vesting Commencement Date, and that nothing in this Notice or the attached documents confers upon you any right to
continue your employment or consulting relationship with the Company for any period of time, nor does it interfere in any way with your right or the Company’s right to terminate that relationship at any time, for any reason, with or without
cause. 
 The per share “Exercise Price” is intended to be at least equal to the fair market value of the
Company’s Common Stock at the date of grant. The Company has attempted in good faith to make the fair market value determination in compliance with applicable tax law although there can be no certainty that the IRS will agree. If the IRS does
not agree and asserts the fair market value at the time of grant is higher than the Exercise Price, the IRS could seek to impose greater taxes on you, including interest and penalties under Internal Revenue Code Section 409A. While we think
this is an unlikely event, we cannot provide absolute assurance and you may want to consult your own tax adviser with any questions.

 CYAN, INC. 
 2006 STOCK PLAN 
 STOCK OPTION AGREEMENT 

1. Grant of Option. Cyan, Inc., a Delaware corporation (the “Company”), hereby grants to
«OPTIONEE» (“Optionee”), an option (the “Option”) to purchase the total number of shares of Common Stock (the “Shares”) set forth in the Notice of Stock Option
Grant (the “Notice”), at the exercise price per Share set forth in the Notice (the “Exercise Price”) subject to the terms, definitions and provisions of the Cyan, Inc. 2006 Stock Plan (the “Plan”)
adopted by the Company, which is incorporated in this Agreement by reference. Unless otherwise defined in this Agreement, the terms used in this Agreement shall have the meanings defined in the Plan. 

2. Designation of Option. This Option is intended to be an Incentive Stock Option as defined in Section 422 of the
Code only to the extent so designated in the Notice, and to the extent it is not so designated or to the extent the Option does not qualify as an Incentive Stock Option under Applicable Law, then it is intended to be and will be treated as a
Nonstatutory Stock Option. 
 Notwithstanding the above, if designated as an Incentive Stock Option, in the event that the
Shares subject to this Option (and all other Incentive Stock Options granted to Optionee by the Company or any Parent or Subsidiary, including under other plans of the Company) that first become exercisable in any calendar year have an aggregate
fair market value (determined for each Share as of the date of grant of the option covering such Share) in excess of $100,000, the Shares in excess of $100,000 shall be treated as subject to a Nonstatutory Stock Option, in accordance with
Section 5(c) of the Plan. 
 3. Exercise of Option. This Option shall be exercisable during its term in
accordance with the Vesting/Exercise Schedule set out in the Notice and with the provisions of Section 9 of the Plan as follows: 
 (a) Right to Exercise. 
 (i) This Option may not be exercised for a
fraction of a share. 
 (ii) In the event of Optionee’s death, disability or other termination of employment, the
exercisability of the Option is governed by Section 5 below, subject to the limitations contained in this Section 3. 

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







 (b) Method of Exercise. 

(i) This Option shall be exercisable by execution and delivery of the Exercise Notice and Restricted Stock Purchase Agreement attached
hereto as Exhibit A (the “Exercise Agreement”) or of any other form of written notice approved for such purpose by the Company which shall state Optionee’s election to exercise the Option, the number of Shares in
respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company pursuant to the provisions of the Plan. Such
written notice shall be signed by Optionee and shall be delivered to the Company by such means as are determined by the Plan Administrator in its discretion to constitute adequate delivery. The written notice shall be accompanied by payment of the
Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price. 
 (ii) As a condition to the exercise of this Option and as further set forth in Section 12 of the Plan, Optionee agrees to make adequate provision for federal, state or other tax withholding
obligations, if any, which arise upon the vesting or exercise of the Option, or disposition of Shares, whether by withholding, direct payment to the Company, or otherwise. 
 (iii) The Company is not obligated, and will have no liability for failure, to issue or deliver any Shares upon exercise of the Option unless such issuance or delivery would comply with the Applicable
Laws, with such compliance determined by the Company in consultation with its legal counsel. This Option may not be exercised until such time as the Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon
such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable federal or state securities or other law or regulation, including any rule under Part 221 of Title 12 of the Code of
Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company may require Optionee to make any representation and warranty to the Company as may be required by the Applicable Laws.
Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on the date on which the Option is exercised with respect to such Shares. 

4. Method of Payment. Payment of the Exercise Price shall be by any of the following, or a combination of the following, at
the election of Optionee: 
 (a) cash; 
 (b) check; or 
 (c) following the date, if any, upon which the Common Stock is a
Listed Security, and if the Company is at such time permitting “same day sale” cashless brokered exercises, delivery of a properly executed exercise notice together with irrevocable instructions to a broker participating in such cashless
brokered exercise program to deliver promptly to the Company the amount required to pay the exercise price (and applicable withholding taxes). 
 5. Termination of Relationship; Early Termination of Option. Following the date of termination of Optionee’s Continuous Service Status for any reason (the “Termination
Date”), Optionee may exercise the Option only as set forth in the Notice and this Section 5. To the extent that Optionee is not entitled to exercise this Option as of the Termination Date, or if Optionee does not exercise this Option
within the Termination Period set forth in the Notice or the termination periods set forth below, the Option shall terminate in its entirety. In no event, may any Option be exercised after the Expiration Date of the Option as set forth in the
Notice. 

  
 2 








 (a) Termination. In the event of termination of Optionee’s Continuous
Service Status other than as a result of Optionee’s disability or death or for Cause (as defined in the Plan), Optionee may, to the extent Optionee is vested in the Option Shares at the Termination Date, exercise this Option during the
Termination Period set forth in the Notice. 
 (b) Other Terminations of Relationship. In connection with any
termination other than a termination covered by Section 5(a), Optionee may exercise the Option only as described below: 

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

(ii) Death of Optionee. In the event of the death of Optionee (a) during the term of this Option and while an
Employee or Consultant of the Company and having been in Continuous Service Status since the date of grant of the Option, or (b) within thirty (30) days after Optionee’s Termination Date, the Option may be exercised at any time within
twelve months following the date of death by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent Optionee was vested in the Option as of the Termination Date.

 (iii) Termination for Cause. In the event Optionee’s Continuous Service Status is terminated for Cause,
the Option shall terminate immediately upon such termination for Cause as set forth in Section 9(b)(iv) of the Plan. In the event Optionee’s employment or consulting relationship with the Company is suspended pending investigation of
whether such relationship shall be terminated for Cause, all Optionee’s rights under the Option, including the right to exercise the Option, shall be suspended during the investigation period, also as set forth in Section 9(b)(iv) of the
Plan. 
 (c) Termination of Option. This Option may terminate prior to its Expiration Date and prior to the dates
specified under Section 5(a) and (b) above under certain circumstances as set forth in Section 14 of the Plan. 

6. Non-Transferability of Option. Except as otherwise set forth in the Notice, this Option may not be transferred in any
manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by him or her. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and
assigns of Optionee. 
 7. Tax Consequences. The Company has not provided any tax advice with respect to this
Option or the disposition of the Shares. Optionee should obtain advice from an appropriate independent professional adviser with respect to the taxation implications of the grant, exercise, assignment, release, cancellation or any other disposal of
this Option (each, a 

  
 3 








 
“Trigger Event”) and on any subsequent sale or disposition of the Shares. Optionee should also take advice in respect of the taxation indemnity provisions under Section 8
below. The per share Exercise Price of the Option is intended to be at least equal to the fair market value of the Company’s Common Stock at the date of grant. The Company has attempted in good faith to make the fair market value determination
in compliance with applicable tax law although there can be no certainty that the IRS will agree. If the IRS does not agree and asserts the fair market value at the time of grant is higher than the Exercise Price, the IRS could seek to impose
greater taxes on Optionee, including interest and penalties under Internal Revenue Code Section 409A. While the Company thinks this is an unlikely event, the Company cannot provide absolute assurance and Optionee may want to consult
Optionee’s own tax adviser with any questions. 
 8. Optionee’s Taxation Indemnity. 

(a) To the extent permitted by law, Optionee hereby agrees to indemnify and keep indemnified the Company and the Company as trustee for
and on behalf of any affiliate entity, in respect of any liability or obligation of the Company and/or any affiliate entity to account for income tax or any other taxation provisions under the laws of Optionee’s country or citizenship and/or
residence to the extent arising from a Trigger Event or arising out of the acquisition, retention and disposal of the Shares. 

(b) The Company shall not be obliged to allot and issue any of the Shares or any interest in the Shares unless and until Optionee has
paid to the Company such sum as is, in the opinion of the Company, sufficient to indemnify the Company in full against any liability the Company has for any amount of, or representing, income tax or any other tax arising from a Trigger Event (the
“Option Tax Liability”), or 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 Optionee within such period as the Company may
then determine. 
 9. Data Protection. 
 (a) To facilitate the administration of the Plan and this Agreement, it will be necessary for the Company (or its payroll administrators) to collect, hold and process certain personal information about
Optionee and to transfer this data to certain third parties such as brokers with whom Optionee may elect to deposit any share capital under the Plan. Optionee consents to the Company (or its payroll administrators) collecting, holding and processing
Optionee’s personal data and transferring this data to the Company or any other third parties insofar as is reasonably necessary to implement, administer and manage the Plan. 

(b) Optionee understands that Optionee may, at any time, view Optionee’s personal data, require any necessary corrections to it or
withdraw the consents herein in writing by contacting the Company, but acknowledges that without the use of such data it may not be practicable for the Company to administer Optionee’s involvement in the Plan in a timely fashion or at all and
this may be detrimental to Optionee. 
 10. Lock-Up Agreement. In connection with the initial public offering of
the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Optionee hereby agrees not to sell, make any


  
 4 








 
short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the registration)
without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days but subject to such extension or extensions as may be required by the underwriters in order to publish
research reports while complying with Rule 2711 of the National Association of Securities Dealers, Inc.) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement
reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 
 11. Governing
Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect
to principles of conflicts of law. 
 12. Effect of Agreement. Optionee acknowledges receipt of a copy of the Plan
and represents that he or she is familiar with the terms and provisions thereof (and has had an opportunity to consult counsel regarding the Option terms), and hereby accepts this Option and agrees to be bound by its contractual terms as set forth
herein and in the Plan. Optionee hereby agrees to accept as binding, conclusive and final all decisions and interpretations of the Plan Administrator regarding any questions relating to the Option. In the event of a conflict between the terms and
provisions of the Plan and the terms and provisions of the Notice and this Agreement, the Plan terms and provisions shall prevail. The Option, including the Plan, constitutes the entire agreement between Optionee and the Company on the subject
matter hereof and supersedes all proposals, written or oral, and all other communications between the parties relating to such subject matter. 
 This Stock Option Agreement will be deemed to be signed by the Optionee upon the Optionee’s signing of the Notice of Stock Option Grant to which it is attached.

 EXHIBIT A 
 CYAN, INC. 
 2006 STOCK PLAN 

EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 

This Agreement (“Agreement”) is made as of
                        , by and between Cyan, Inc., a Delaware corporation (the “Company”), and
«OPTIONEE» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the Company’s 2006 Stock Plan (the
“Plan”). 
 1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser hereby
elects to exercise his or her option to purchase                         shares of the Common Stock (the
“Shares”) of the Company under and pursuant to the Plan and the Stock Option Agreement granted «GrantDate» (the “Option Agreement”). The purchase price for the Shares shall be
$«ExercisePrice» per Share for a total purchase price of $                    . The term “Shares” refers to the
purchased Shares and all securities received in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution and delivery of
this Agreement in accordance with the provisions of Section 3(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be purchased by Purchaser (which shall be issued in
Purchaser’s name) against payment of the exercise price therefor by Purchaser by any method listed in Section 4 of the Option Agreement. 
 3. Limitations on Transfer. In addition to any other limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the
Shares except in compliance with the provisions below and applicable securities laws. 
 (a) Right of First Refusal.
Before any Shares held by Purchaser or any transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or
its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section 3(a) (the “Right of First Refusal”). 

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







 (ii) Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (iii) below. 
 (iii) Purchase
Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 3(a) shall be the Offered Price. If the Offered Price includes consideration other than cash,
the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (iv) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding
indebtedness, or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (v) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as
provided in this Section 3(a), then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 60 days after the
date of the Notice and provided further that any such sale or other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to
apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to change the price or other terms to make them more
favorable to the Proposed Transferee, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred.

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

  
 2 








 (b) Involuntary Transfer. 

(i) Company’s Right to Purchase upon Involuntary Transfer. In the event, at any time after the date of this Agreement,
of any transfer by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(a)(vi) above) of all or a portion of the Shares by the record holder thereof,
the Company shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser for the Shares pursuant to this Agreement (as adjusted for any stock splits, stock dividends and the like) or the Fair
Market Value of the Shares on the date of transfer. Upon such a transfer, the person acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a
period of thirty (30) days following receipt by the Company of written notice by the person acquiring the Shares. 
 (ii)
Price for Involuntary Transfer. With respect to any stock to be transferred pursuant to Section 3(b)(i), the Fair Market Value per Share shall be a price set by the Board of Directors of the Company in good faith using a
reasonable valuation method in a reasonable manner in accordance with Section 409A of the Code. The Company shall notify Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written
notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the valuation as determined by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an
independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne equally by the Company and the Purchaser. 
 (c) Assignment. The right of the Company to purchase any part of the Shares may be assigned in whole or in part to any stockholder or stockholders of the Company or other persons or
organizations. 
 (d) Restrictions Binding on Transferees. All transferees of Shares or any interest therein will
receive and hold such Shares or interest subject to the provisions of this Agreement. Any sale or transfer of the Company’s Shares shall be void unless the provisions of this Agreement are satisfied. 

(e) Termination of Rights. The right of first refusal granted the Company by Section 3(a) above and the option to
repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(b) above shall terminate upon the first sale of Common Stock of the Company to the general public pursuant to a registration statement filed with and
declared effective by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the rights to repurchase and the right of first refusal described in Sections 3(a)
and 3(b) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 5(a)(ii) herein and delivered to Purchaser. 

  
 3 








 4. Investment and Taxation Representations. In connection with the purchase of
the Shares, Purchaser represents to the Company the following: 
 (a) Purchaser is aware of the Company’s business affairs
and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not
with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to
any person or entity. 
 (b) Purchaser understands that the Shares have not been registered under the Securities Act by reason
of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
 (c) Purchaser further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is
available. Purchaser further acknowledges and understands that the Company is under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the
transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company. 
 (d) Purchaser is familiar with the provisions of Rules 144 and 701, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities”
acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser understands that the Company provides no assurances as
to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or Rule 701, which rules require, among other things, that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934, as
amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant
to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the restrictions set forth in paragraph (e) below. 
 (e) Purchaser further understands that in the event all of the applicable requirements of Rule 144 or 701 are not satisfied, registration under the Securities Act, compliance with Regulation A,
or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales,
and that such persons and their respective brokers who participate in such transactions do so at their own risk. 

  
 4 








 (f) Purchaser understands that Purchaser may suffer adverse tax consequences as a result of
Purchaser’s purchase or disposition of the Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the purchase or disposition of the Shares and that Purchaser is not relying on
the Company for any tax advice. 
 (g) Purchaser understands that the per share “Exercise Price” for the Shares is
intended to be at least equal to the fair market value of the Company’s Common Stock at the date of grant and that the Company has attempted in good faith to make the fair market value determination in compliance with applicable tax law
although there can be no certainty that the IRS will agree. Purchaser understands that if the IRS does not agree and asserts that the fair market value at the time of grant is higher than the Exercise Price, the IRS could seek to impose greater
taxes on Purchaser, including interest and penalties under Internal Revenue Code Section 409A. 
 5. Restrictive
Legends and Stop-Transfer Orders. 
 (a) Legends. The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable state and federal corporate and securities laws): 
 (i) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED UNLESS EFFECTED PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR UNDER ANOTHER EXEMPTION AVAILABLE UNDER THE SECURITIES ACT OF 1933 (AS TO WHICH AVAILABILITY THE
COMPANY MAY REQUIRE THE SELLER/TRANSFEROR TO PROVIDE AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY). 
 (ii) THE SHARES
REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 

(b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure compliance with the restrictions referred to herein,
the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

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

  
 5 








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

7. Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of
the Company or the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the
Company however or whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days but subject to such
extension or extensions as may be required by the underwriters in order to publish research reports while complying with Rule 2711 of the National Association of Securities Dealers, Inc.) from the effective date of such registration as may be
requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 

8. Tax Consequences. Purchaser should obtain advice from an appropriate independent professional adviser with respect to
the taxation implications of the grant, issuance, purchase, retention, assignment, release, cancellation, sale or any other disposal of the Shares (each, a “Trigger Event”). Participant should also take advice in respect of the
taxation indemnity provisions under Section 9 below. 
 9. Purchaser’s Taxation Indemnity. 

(a) To the extent permitted by law, Purchaser hereby agrees to indemnify and keep indemnified the Company and the Company as trustee for
and on behalf of any affiliate entity, in respect of any liability or obligation of the Company and/or any affiliate entity to account for income tax or any other taxation provisions under the laws of Purchaser’s country or citizenship and/or
residence to the extent arising from a Trigger Event. 
 (b) The Company shall not be obliged to allot and issue any of the
Shares or any interest in the Shares unless and until Purchaser has paid to the Company such sum as is, in the opinion of the Company, sufficient to indemnify the Company in full against any liability the Company has for any amount of, or
representing, income tax or any other tax arising from a Trigger Event (the “Shares Tax Liability”), or Purchaser has made such other arrangement as in the opinion of the Company will ensure that the full amount of any Shares Tax
Liability will be recovered from Purchaser within such period as the Company may then determine. 
 10. Data
Protection. 
 (a) To facilitate the administration of the Plan and this Agreement, it will be necessary for the Company
(or its payroll administrators) to collect, hold and process certain personal information about Purchaser and to transfer this data to certain third parties such as brokers with whom Purchaser may elect to deposit any share capital under the Plan.
Purchaser consents to the Company (or its payroll administrators) collecting, holding and processing Purchaser’s personal data and transferring this data to the Company or any other third parties insofar as is reasonably necessary to implement,
administer and manage the Plan.

 (b) Purchaser understands that Purchaser may, at any time, view Purchaser’s personal
data, require any necessary corrections to it or withdraw the consents herein in writing by contacting the Company, but acknowledges that without the use of such data it may not be practicable for the Company to administer Purchaser’s
involvement in the Plan in a timely fashion or at all and this may be detrimental to Purchaser. 
 11.

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