OPTION AWARD AGREEMENT 

THIS OPTION AWARD AGREEMENT (this “Agreement”) is entered into by and between the Company and the Participant as of the Grant
Date set forth in the Grant Notice to which this Agreement is attached. Capitalized terms used herein without definition have the meanings ascribed to such terms in the Plan. 

WHEREAS, the Plan provides for the grant of Stock Options; and 

WHEREAS, the Committee has determined that it would be in the best interests of the Company and its members to grant the Participant an award
of Options on the terms and subject to the conditions set forth in this Agreement and the Plan. 
 NOW THEREFORE, for and in consideration
of the premises and the covenants of the parties contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, for themselves and their successors and
assigns, hereby agree as follows: 
 1. Grant of Options. 

(a) Grant. The Company hereby grants to the Participant the number of Options set forth in the Grant Notice on the terms and conditions
set forth in the Grant Notice, this Agreement, and the Plan. Each Option represents the right to purchase one Share. 
 (b) Incorporation
by Reference. The provisions of the Plan are incorporated herein by reference. Except as otherwise expressly set forth herein, this Agreement shall be construed in accordance with the provisions of the Plan. 

2. Vesting. 
 (a) Two
thirds (2⁄3) of the Options (the “Service Options”) shall vest and become exercisable with respect to twenty-five percent (25%) of the Service
Options on the first anniversary of the Grant Date and with respect to six and one quarter percent (6.25%) quarterly thereafter, subject to the Participant not incurring a Separation from Service prior to the applicable vesting date. For the
avoidance of doubt, the Service Options will be fully vested and exercisable on the fourth anniversary of the Grant Date. 
 (b) The
remaining one third (1⁄3) of the Options (the “Return Target Options”) will vest and become exercisable if (A) Participant is, and has been,
continuously employed by the Company or its Subsidiaries from the date of Agreement through the date of a Change in Control and (B) if upon the consummation of such Change in Control, the cumulative total of all cash distributions made to, or
other cash proceeds received by, the Investor Fund (as defined below) (excluding management or transaction fees and expenses, any other advisory fees and expenses, any board fees and expenses or any other expenses borne by the Investor Fund) in
respect of its ownership of equity or debt securities of the Company or any of its Subsidiaries or any loans provided by the Investor Fund during the life of the Investor Fund’s investment period, equals or exceeds the Investor Returns Target
(as defined below) (the “Vesting Condition”). 

 (c) As used in this Agreement, (i) the term “Investor Fund” shall mean
one or more equity buy-out investment funds (including Vista Equity Partners Fund VI, L.P.) managed or controlled by VEPF Management, L.P. or any successor management company, and any of such fund’s
respective portfolio companies, (excluding the Company and its Subsidiaries) and their respective partners, members, directors, employees, stockholders, agents, any successor by operation of law (including by merger) of any such Person, and any
entity that acquires all or substantially all of the assets of any such Person in a single transaction or series of related transactions and (ii) the term “Investor Returns Target” shall mean $1,170,000,000. For purposes of
calculating distributions and proceeds under clause (B) immediately above, all distributions made to the Investor Fund will be net of all accrued but unpaid management fees, all expenses associated with the ultimate sale of the Company business
borne by the Investor Fund, and assuming, for purposes of the calculation made above, the vesting (and exercise, if applicable) (prior to the calculation of distributions and proceeds under clause (B) immediately above) of all outstanding
options, warrants and other outstanding rights to acquire capital stock of the Company. For the avoidance of doubt, the Return Target Options shall expire, and shall not vest or become exercisable, if the Vesting Condition has not been satisfied as
of the date of a Change in Control. 
 (d) Notwithstanding anything to the contrary in the Plan, as used in this Agreement, (i) the
term “Change in Control” means the first to occur of (A) the Sale of the Company (as defined below), (B) the sale or transfer to any third party of Common Stock or shares of the capital stock of any Subsidiary by the holders
thereof as a result of which any Person or group other than the Investors (as defined below) obtains possession of voting power (under ordinary circumstances) to elect a majority of the Company’s board of managers or the board of directors or
any other governing body of the applicable Subsidiary, or (C) at any time following the Company’s initial public offering, a sale of shares of the Company by the Investor following which the cumulative total of all cash distributions made
to, or other cash proceeds received by, the Investor Fund (excluding management or transaction fees and expenses, any other advisory fees and expenses, any board fees and expenses or any other expenses borne by the Investor Fund) in respect of its
ownership of equity or debt securities of the Company or any of its Subsidiaries or any loans provided by the Investor Fund during the life of the Investor Fund’s investment period, equals or exceeds the Investor Returns Target; provided that,
for purposes of calculating distributions and proceeds under this clause (C), all distributions made to the Investor Fund will be net of all accrued but unpaid management fees, all expenses associated with the Sale of the Company borne by the
Investor Fund, and assuming, for purposes of the calculation made above, the vesting (and exercise, if applicable) (prior to the calculation of the Investor Return) of all outstanding options, warrants and other outstanding rights to acquire capital
stock of the Company; (ii) the term “Sale of the Company” means (A) any sale or transfer by the Company or any of the Subsidiaries of all or substantially all (as defined under Delaware law) of their assets on a
consolidated basis, or (B) any consolidation, merger or reorganization of the Company or any of its Subsidiaries with or into any other entity or entities as a result of which any Person or group other than the Investors obtains possession of
voting power (under ordinary circumstances) to elect a majority of the surviving entity’s board of directors or, in the case of a surviving entity which is not a corporation, governing body; and (iii) the term “Investors”
means Vista Equity Partners Fund VI, L.P., Vista Equity Partners Fund VI-A, L.P., VEPF VI FAF, L.P. and/or any transferee of Vista Equity Partners Fund VI, L.P., Vista Equity Partners Fund VI-A, L.P., VEPF VI FAF, L.P. and any Affiliate of any of the foregoing Persons that holds Common Stock. 

 3. Exercise of the Option. 

(a) Right to Exercise. The Options shall be exercisable in accordance with the terms set forth in this Agreement. The Options, to the
extent exercisable, may be exercised in whole or in part. No Option may be exercised after it expires. No Shares will be issued upon the exercise of any Option unless the issuance and exercise comply with all Applicable Laws. For income tax
purposes, Shares will be considered transferred to the Participant on the date the Participant properly exercises an Option. No fraction of a Share shall be issued by the Company upon exercise of the Options or accepted by the Company in payment of
the Exercise Price; rather, the Participant shall provide a cash payment for such amount as is necessary to effect the issuance and acceptance of only whole Shares. 

(b) Method of Exercise. The Participant may exercise the Options by delivering an exercise notice in a form approved by the Company
(the “Exercise Notice”). The Exercise Notice must state the Participant’s election to exercise the Options, the number of Shares that are being purchased, and any other representations and agreements that may be required by the
Company. Together with the Exercise Notice, the Participant must tender payment of the aggregate Exercise Price for all Shares exercised and all applicable withholding and other taxes. The Options shall be deemed to be exercised upon receipt by the
Company of a fully executed Exercise Notice and payment of the aggregate Exercise Price and all applicable withholding and other taxes. 

(c) Method of Payment. If the Participant elects to exercise the Options, the Participant must pay the aggregate Exercise Price, as
well as any applicable withholding or other taxes, in accordance with any of the payment methods set forth in, and approved by the Committee pursuant to, Section 6.3(d) of the Plan (or any successor sections). The Company may suspend, or
eliminate, various forms of permissible payment of the Exercise Price from time to time in its sole discretion. Further, notwithstanding any provision within this Agreement to the contrary, if the Participant is resident or provides services outside
of the United States, the Company may require that the Participant (or in the event of the Participant’s death, the Participant’s legal representative, as the case may be) exercise the Options only by means of a “same day sale”
transaction (either a “sell-all” transaction or a “sell-to-cover” transaction) as it determines in its sole
discretion, or may require the Participant to sell any Shares acquired under the Plan immediately or within a specified period following the Participant’s Separation from Service (in which case, the Participant hereby agrees that the Company
shall have the authority to issue sale instructions in relation to such Shares on the Participant’s behalf). 
 (d) Restrictions on
Exercise. The Participant may not exercise any Option (i) if it is an Incentive Stock Option and the Plan has not been approved by the Stockholders or (ii) if the issuance of Shares upon exercise or the method of payment for those
Shares would constitute a violation of any Applicable Law or Company policy. 
 4. Change in Control. Upon the consummation of a
Change in Control, any Service Option which were unvested immediately prior to such Change in Control shall be deemed vested (such Options which are subject to accelerated vesting being referred to as the “Accelerated Options”). The
Participant hereby agrees that upon a Change in Control, the Accelerated Options shall be deemed to be automatically exercised through a cashless exercise and Participant shall have no further rights under the Accelerated Options other than payment
of the consideration, if any, (less any applicable taxes and withholdings) to be paid to the Participant (whether in the form of cash or stock) in respect of such deemed exercise of the Accelerated Options as of the Change in Control. 

 5. Rights as Stockholder. Until such time as the Options have been exercised pursuant
to Section 3 and Shares have been issued to the Participant, the Participant shall have no rights as a stockholder, including, without limitation, any right to dividends or other distributions or any right to vote, and no
adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of any such shares of Common Stock, except as otherwise specifically provided for in the Plan or this Agreement. 

6. Taxes. 
 (a) The
Participant acknowledges and agrees that, regardless of any action taken by the Company or, if different, the Affiliate that employs the Participant (the “Employer”), the ultimate liability for all income tax, social insurance,
payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant’s participation in the Plan and legally applicable or deemed applicable to the Participant even
if technically due by the Company or an Affiliate (“Tax-Related Items”) is and remains the Participant’s responsibility and may exceed the amount, if any, actually withheld by the Company
or the Employer. The Participant further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with
any aspect of the Options or the underlying Shares, including, but not limited to, the grant, vesting or exercise of the Options, the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends and (ii) do not
commit to and are under no obligation to structure the terms of the grant or any aspect of the Options to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any particular
tax result. Further, if the Participant is subject to Tax-Related Items in more than one jurisdiction, the Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may
be required to withhold or account for Tax-Related Items in more than one jurisdiction. 
 (b) To
the extent that Tax-Related Items are payable, the Participant shall make arrangements satisfactory to the Company for the satisfaction of obligations for the payment of
Tax-Related Items relating to the Options or the Company may mandate the method for satisfying Tax-Related Items, which arrangements include the delivery of cash or cash
equivalents, Shares (including previously owned Shares, net exercise, a broker-assisted sale, or, if permitted by the Committee, other cashless withholding or reduction of the amount of Shares otherwise issuable or delivered pursuant to this Award),
other property, or any other legal consideration the Committee deems appropriate. If the Participant fails to satisfy such Tax-Related Items, the Company may refuse to issue or transfer any Shares otherwise
required to be issued pursuant to this Agreement. If such Tax-Related Items are satisfied through net exercise or the surrender of previously owned Shares, the maximum number of Shares that may be so withheld
(or surrendered) shall be the number of Shares that have an aggregate Fair Market Value on the date of withholding or surrender approximately equal to the aggregate amount of such Tax-Related Items determined
based on the greatest withholding rates for Tax-Related Items that may be used without creating adverse accounting treatment for the Company with respect to the Options, as determined by the Committee. If the
obligation for Tax-Related Items is satisfied through net exercise, for tax 

 
purposes, the Participant is deemed to have been issued the full number of Shares subject to the Options, notwithstanding that a number of Shares are held back solely for the purpose of paying
the Tax-Related Items. The Participant will have no further rights with respect to any Shares that are retained by the Company pursuant to this provision. In the event of over-withholding, the Participant may
receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or if not refunded, the Participant may be able to seek a refund from the local tax authorities. In the event of under-withholding, the
Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Employer. 

(c) If the Options granted hereunder constitute Incentive Stock Options and the Participant makes any disposition of Shares delivered upon
exercise of such Options under the circumstances described in Section 421(b) of the Code (relating to certain disqualifying dispositions), the Participant must notify the Company of such disposition within 10 days following such
disposition. 
 (d) The Participant acknowledges that there may be adverse tax consequences upon the receipt, vesting or exercise of this
Award or disposition of the underlying Shares and that Participant has been advised, and hereby is advised, to consult a tax advisor. The Participant represents that the Participant is in no manner relying on the Board, the Committee, the Company or
an Affiliate or any of their respective managers, directors, officers, employees or authorized representatives (including attorneys, accountants, consultants, bankers, lenders, prospective lenders and financial representatives) for tax advice or an
assessment of such tax consequences. 
 7. Non-Transferability. Except as set forth in
Section 6.3(e) of the Plan, the Options may not, at any time prior to being settled, be assigned, alienated, pledged, attached, sold, or otherwise transferred or encumbered by the Participant, other than by will or by the laws of descent and
distribution, and are exercisable during the Participant’s lifetime only by him or her (or his or her legal representative in the event of incapacity). Any such purported assignment, alienation, pledge, attachment, sale, transfer, or
encumbrance shall be void and unenforceable against the Company. 
 8. Miscellaneous. 

(a) Clawback. All awards, amounts, and benefits received or outstanding under the Plan will be subject to clawback, cancellation,
recoupment, rescission, payback, reduction, or other similar action in accordance with the terms of any Company clawback or similar policy or any Applicable Law related to such actions, as may be in effect from time to time. The Participant
acknowledges and expressly agrees to the Company’s application, implementation, and enforcement of any applicable Company clawback or similar policy that may apply to the Participant, whether adopted before or after the Grant Date (including
the forfeiture, clawback, and detrimental conduct terms contained in Section 13.22 of the Plan as of the Grant Date (and any successor terms)), and any term of Applicable Law relating to clawback, cancellation, recoupment, rescission, payback,
or reduction of compensation, and the Company may take such actions as may be necessary to effectuate any such policy or Applicable Law, without further consideration or action. 

 (b) Compliance with Laws. The grant of Options and the issuance of Shares hereunder
shall be subject to, and shall comply with, any applicable requirements of any foreign and U.S. federal and state securities laws, rules, and regulations (including, without limitation, the provisions of the Securities Act, the Exchange Act, and in
each case any respective rules and regulations promulgated thereunder) and any other law, rule, regulation, or exchange requirement applicable thereto. No shares of Common Stock will be issued hereunder if such issuance would constitute a violation
of any applicable law or regulation or the requirements of any stock exchange or market system upon which the Common Stock may then be listed. In addition, shares of Common Stock will not be issued hereunder unless (a) a registration statement
under the Securities Act is in effect at the time of such issuance with respect to the shares to be issued or (b) in the opinion of legal counsel to the Company, the shares to be issued are permitted to be issued in accordance with the terms of
an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary
for the lawful issuance and sale of any shares of Common Stock hereunder will relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority has not been obtained. As a condition to any
issuance of Common Stock hereunder, the Company may require the Participant to satisfy any requirements that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with
respect to such compliance as may be requested by the Company. 
 (c) Not a Public Offering. If the Participant is employed or
resident outside the United States, the grant of the Options is not intended to be a public offering of securities in the Participant’s country of employment (or country of residence, if different). The Company has not submitted any
registration statement, prospectus or other filings with the local securities authorities (unless otherwise required under local law), and the grant of the Options is not subject to the supervision of the local securities authorities. 

(d) Insider Trading; Market Abuse Laws. By participating in the Plan, the Participant agrees to comply with the Company’s
policy on insider trading (to the extent that it is applicable to the Participant). The Participant further acknowledges that, depending on the Participant’s or his or her broker’s country of residence or where the Shares are listed, the
Participant may be subject to insider trading restrictions and/or market abuse laws which may affect the Participant’s ability to accept, acquire, sell or otherwise dispose of Shares, rights to Shares (e.g., Options) or rights linked to the
value of Shares, during such times the Participant is considered to have “inside information” regarding the Company as defined by the laws or regulations in the Participant’s country. Local insider trading laws and regulations may
prohibit the cancellation or amendment of orders the Participant places before he or she possessed inside information. Furthermore, the Participant could be prohibited from (i) disclosing the inside information to any third party (other than on
a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. The Participant understands that third parties include fellow employees. Any restrictions under these laws or
regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Participant acknowledges that it is the Participant’s responsibility to comply with any applicable
restrictions, and that the Participant should therefore consult his or her personal advisor on this matter. 

 (e) Repatriation; Compliance with Law. The Participant agrees to repatriate
all payments attributable to the Shares and/or cash acquired under the Plan in accordance with applicable foreign exchange rules and regulations in the Participant’s country of employment (and country of residence, if different). In addition,
the Participant agrees to take any and all actions, and consents to any and all actions taken by the Company and any of its Affiliates, as may be required to allow the Company and any of its Affiliates to comply with local laws, rules and/or
regulations in the Participant’s country of employment (and country of residence, if different). Finally, the Participant agrees to take any and all actions as may be required to comply with the Participant’s personal obligations under
local laws, rules and/or regulations in his or her country of employment (and country of residence, if different). 
 (f) Successors.
The terms of this Agreement shall be binding upon and inure to the benefit of the Company and its successors and assigns, and of the Participant and the beneficiaries, executors, administrators, and heirs of the Participant. 

(g) No Waiver; Amendment. No waiver of any right hereunder by any party shall operate as a waiver of any other right, or as a waiver of
the same right with respect to any subsequent occasion for its exercise, or as a waiver of any right to damages. No waiver by any party of any breach of this Agreement shall be held to constitute a waiver of any other breach or a waiver of the
continuation of the same breach. This Agreement may be amended at any time by the Committee, except that no amendment may, without the Participant’s consent, materially impair the Participant’s rights under the Award. 

(h) Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability
of any other provision of this Agreement, and each other provision of this Agreement shall be severable and enforceable to the extent permitted by law. 

(i) Nature of Grant. In accepting the Options, the Participant acknowledges and agrees that: 

(i) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated
by the Company, in its sole discretion, at any time (subject to any limitations set forth in the Plan); 
 (ii) the grant of the Options is
exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of Options, or benefits in lieu of Options, even if Options or other awards have been granted in the past; 

(iii) all decisions with respect to future awards, if any, will be at the sole discretion of the Company; 

(iv) the Participant’s participation in the Plan is voluntary; 

(v) the Options and the Participant’s participation in the Plan shall not create a right to employment or be interpreted as forming an
employment contract with the Company or any of its Affiliates and shall not interfere with the ability of the Company or the Employer, as applicable, to terminate the Participant’s employment relationship (as otherwise may be permitted under
local law); 

 (vi) unless otherwise agreed with the Company, the Options and any Shares acquired upon
exercise of the Options, and the income from and value of the same, are not granted as consideration for, or in connection with, any service the Participant may provide as a director of any Subsidiary or Affiliate; 

(vii) the Options and any Shares acquired under the Plan and the income and value of the same, are not part of normal or expected
compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, holiday
pay, pension or retirement or welfare benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company, the Employer or any of their Affiliates; 

(viii) the future value of the Shares underlying the Options is unknown, indeterminable, and cannot be predicted with certainty; 

(ix) no claim or entitlement to compensation or damages shall arise from forfeiture of the Options resulting from the Participant’s
Separation from Service (for any reason whatsoever and whether or not in breach of local labor laws or later found invalid) and, in consideration of the Options, the Participant agrees not to institute any claim against the Company or the Employer;

 (x) for purposes of the Options, the Participant’s employment will be considered terminated as of the date the Participant is no
longer actively providing service (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is providing service or the terms of the
Participant’s employment or service agreement, if any), and unless otherwise determined by the Company, the Participant’s right to vest in the Options and the period (if any) during which the Participant may exercise the Options after such
termination of the Participant’s service will terminate as of such date and will not be extended by any notice period (e.g., the Participant’s period of service would not include any contractual notice period or any period of “garden
leave” or similar period mandated under employment laws in the jurisdiction where Participant is providing service or the terms of Participant’s employment or service agreement, if any); the Committee or its delegate shall have the
exclusive discretion to determine when the Participant is no longer actively providing service for purposes of his or her Award (including whether the Participant may still be considered to be providing service while on a leave of absence); 

(xi) the Options and the benefits evidenced by this Agreement do not create any entitlement not otherwise specifically provided for in the
Plan or provided by the Company in its discretion, to have the Options or any such benefits transferred to, or assumed by, another company, nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting
the Shares; and 

 (xii) if the Participant’s local currency is different than the U.S. dollar, neither
the Company nor any of its Affiliates shall be liable for any foreign exchange rate fluctuation between the Participant’s local currency and the U.S. dollar that may affect the value of the Options or any amounts due to the Participant pursuant
to the exercise of the Options or the subsequent sale of any Shares acquired upon exercise of the Options. 
 (j) Appendix.
Notwithstanding any provisions in this Agreement, the Options shall be subject to any additional or different terms and conditions set forth in the Appendix to this Agreement for certain country or countries (the “Appendix”).
Moreover, if the Participant relocates to any country included in the Appendix, the special terms and conditions for such country will apply to the Participant, to the extent the Company determines that the application of such terms and conditions
is necessary or advisable for legal or administrative reasons or the Company may establish additional terms to facilitate the Participant’s relocation. The Appendix constitutes part of this Agreement. 

(k) Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Participant’s
participation in the Plan, on the Options, and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the Participant to sign any additional
agreements or undertakings that may be necessary to accomplish the foregoing. 
 (l) Entire Agreement. This Agreement (including the
Appendix), the Grant Notice, and the Plan contain the entire agreement and understanding of the parties hereto with respect to the subject matter contained herein and supersede all prior communications, representations, and negotiations with respect
thereto. 
 (m) Bound by the Plan. By signing this Agreement, the Participant acknowledges that the Participant has received a copy
of the Plan and has had an opportunity to review the Plan and agrees to be bound by all the terms and provisions of the Plan. In the event of any conflict between the Plan and this Agreement, this Agreement shall control. 

(n) Governing Law. The Participant acknowledges and expressly agrees to the governing law terms of Section 13.9 of the Plan (and
any successor terms) and the jurisdiction and waiver of jury trial terms of Section 13.10 of the Plan (and any successor terms). 
 (o)
Business Days. If any time period for giving notice or taking action hereunder expires on a day that is a Saturday, Sunday, or holiday in the state in which the Company’s principal executive office is located, the time period shall be
automatically extended to the business day immediately following such Saturday, Sunday, or holiday. 
 (p) Headings. The headings of
the Sections hereof are provided for convenience only and are not to serve as a basis for interpretation or construction, and shall not constitute a part, of this Agreement. 

(q) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original, but all
of which taken together shall constitute one and the same instrument. 

 (r) Section 409A of the Code. It is intended that the Options
granted pursuant to this Agreement and the provisions of this Agreement be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and all provisions of this Agreement shall be construed and
interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A of the Code. 
 (s)
Language. If the Participant is resident in a country where English is not an official language, the Participant acknowledges and agrees that it is his or her express intent that this Agreement and the Plan and all other documents,
notices and legal proceedings entered into, given or instituted pursuant to the Options be drawn up in English. Further, the Participant acknowledges that he or she is sufficiently proficient in English to understand the terms and conditions of this
Agreement and any documents related to the Plan or has had the ability to consult with an advisor who is sufficiently proficient in the English language. If the Participant has received this Agreement or any other document related to the Plan
translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control. 

(t) Data Privacy. The Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in
electronic or other form, of the Participant’s personal data as described in this Agreement, the Grant Notice and any other grant materials by and among, as necessary and applicable, the Company and its Affiliates, for the
exclusive purpose of implementing, administering and managing the Participant’s participation in the Plan. 
 The
Participant understands that the Company, its Affiliates and/or the Employer may hold certain personal information about the Participant, specifically, [the Participant’s name, home address, email address and telephone number, date of birth,
social security or insurance number, passport number or other identification number, salary, nationality, and any Shares or directorships held in the Company, and details of the Options or any other entitlement to Shares, canceled, exercised,
vested, unvested or outstanding in the Participant’s favor] (“Data”), for the purpose of implementing, administering and managing the Plan. 

The Participant understands that Data will be transferred to Fidelity Stock Plan Services or such other stock plan service provider as may
be selected by the Company in the future, which is assisting the Company with the implementation, administration and management of the Plan. The Participant understands that the recipients of Data may be located in the United States or elsewhere,
and that the recipients’ country (e.g., the United States) may have different data privacy laws and protections than the Participant’s country. If the Participant is employed outside the United States, the Participant understands that the
Participant may request a list with the names and addresses of any potential recipients of Data by contacting his or her local human resources representative. The Participant authorizes the Company, the applicable stock plan service provider and any
other possible recipients that may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer Data, in electronic or other form, for the sole purpose of
implementing, administering and managing the Participant’s participation in the Plan. The Participant 

 
understands that Data will be held only as long as is necessary to implement, administer and manage the Participant’s participation in the Plan. If the Participant is employed outside the
United States, the Participant understands that he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in
any case without cost, by contacting in writing his or her local human resources representative. Further, the Participant understands that he or she is providing the consents herein on a purely voluntary basis. If the Participant does not consent,
or if the Participant later seeks to revoke the Participant’s consent, his or her service status and career will not be affected; the only consequence of refusing or withdrawing the Participant’s consent is that the Company would not be
able to grant the Options or other equity awards to the Participant or administer or maintain such awards. Therefore, the Participant understands that refusing or withdrawing the Participant’s consent may affect his or her ability to
participate in the Plan. For more information on the consequences of the Participant’s refusal to consent or withdrawal of consent, the Participant understands that the Participant may contact his or her local human resources representative.

 (u) Consent to Electronic Delivery; Electronic Signature. In lieu of receiving documents in paper format, the Participant
agrees, to the fullest extent permitted by law, to accept electronic delivery of any documents that the Company may be required to deliver (including, without limitation, prospectuses, prospectus supplements, grant or award notifications and
agreements, account statements, annual and quarterly reports and all other forms of communications) in connection with this and any other Award made or offered by the Company. Electronic delivery may be via a Company electronic mail system or by
reference to a location on a Company intranet or third party website to which the Participant has access. The Participant hereby consents to any and all procedures the Company has established or may establish for an electronic signature system for
delivery and acceptance of any such documents that the Company may be required to deliver, and agrees that the Participant’s electronic signature is the same as, and shall have the same force and effect as, the Participant’s manual
signature.

 APPENDIX TO THE AGREEMENT 

COUNTRY-SPECIFIC TERMS, CONDITIONS AND NOTIFICATIONS 

Terms and Conditions 
 This Appendix includes
additional terms and conditions that govern the Options granted to the Participant under the Plan if the Participant resides and/or works outside of the United States. Capitalized terms used but not defined herein shall have the meanings ascribed to
them in the Grant Notice, the Plan and/or the Agreement to which this Appendix is attached. 
 If the Participant is a citizen or resident of a country
other than the one in which the Participant is currently working and/or residing, transfers to another country after the Grant Date, is a consultant, changes employment status to a consultant, or is considered a resident of another country for local
law purposes, the Company shall, in its discretion, determine the extent to which the terms and conditions contained herein shall be applicable to the Participant. References to the Employer shall include any entity that engages the
Participant’s services. 
 Notifications 

This Appendix also includes information regarding securities, tax, and certain other issues of which the Participant should be aware with respect to
participation in the Plan. The information is provided solely for the Participant’s convenience and is based on the securities, tax, and other laws in effect in the respective countries as of June 2021. Such laws are often complex and
change frequently. As a result, the Company strongly recommends that the Participant not rely on the information noted herein as the only source of information relating to the consequences of participation in the Plan because the information may be
out of date by the time the Participant vests in, exercises or receives Shares underlying the Options or sells any Shares. 
 In addition, the information
contained in this Appendix is general in nature and may not apply to the Participant’s particular situation, and the Company is not in a position to assure the Participant of any particular result. Accordingly, the Participant should seek
appropriate professional advice as to how the applicable laws in the Participant’s country may apply to his or her situation. 
 Finally, the
Participant understands that if the Participant is a citizen or resident of a country other than the one in which he or she is currently residing and/or working, transfer to another country after the Grant Date, or is considered a resident of
another country for local law purposes, the notifications contained herein may not be applicable to the Participant in the same manner. 
  

 SINGAPORE 

Securities Law Information. The grant of the Options under the Plan is being made pursuant to the “Qualifying Person” exemption under section
273(1)(f) of the Securities and Futures Act (Chapter 289, 2006 Ed.) (“SFA”). The Plan has not been and will not be lodged or registered as a prospectus with the Monetary Authority of Singapore and is not regulated by any financial
supervisory authority pursuant to any legislation in Singapore. Accordingly, statutory liability under the SFA in relation to the content of prospectuses would not apply. The Participant should note that the Options are subject to section 257 of the
SFA and the Participant will not be able to make any subsequent sale of the underlying Shares in Singapore, or any offer of such subsequent sale of the Shares subject to the Options in Singapore, unless such sale or offer is made (i) after
six (6) months from the date of grant or (ii) pursuant to the exemptions under Part XIII Division (1) Subdivision (4) (other than section 280) of the SFA. 

UNITED KINGDOM 
 1. Taxes. This
provision shall supplement Section 5 of the Agreement: 
 Without limitation to Section 5 of the Agreement, the Participant
agrees that he or she is liable for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items, as and when requested by the Company, the Employer or
by Her Majesty’s Revenue and Customs (“HMRC”) (or any other tax authority or any other relevant authority). The Participant also agrees to indemnify and keep indemnified the Company and the Employer against any Tax-Related Items that they are required to pay or withhold or have paid or will pay on the Participant’s behalf to HMRC (or any other tax authority or any other relevant authority). 

Notwithstanding the foregoing, if the Participant is a director or executive officer (as within the meaning of Section 13(k) of the Exchange Act), the
terms of the immediately foregoing provision will not apply. In the event that the Participant is a director or executive officer and income tax due is not collected from or paid by the Participant by within 90 days after the U.K. tax year in which
an event giving rise to the indemnification described above occurs, the amount of any uncollected tax may constitute a benefit to the Participant on which additional income tax and national insurance contributions may be payable. The Participant
acknowledges that the Participant ultimately will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company or the Employer (as applicable)
for the value of any employee national insurance contributions due on this additional benefit, which the Company and/or the Employer may recover from the Participant at any time thereafter by any of the means referred to in Section 5 of the
Agreement. 
 2. Exclusion of Claim. The Participant acknowledges and agrees that the Participant will have no entitlement to compensation or
damages insofar as such entitlement arises or may arise from the Participant ceasing to have rights under or to be entitled to the Options, whether or not as a result of a Separation from Service (whether the termination is in breach of contract or
otherwise), or from the loss or diminution in value of the Options. Upon the grant of the Options, the Participant will be deemed to have waived irrevocably any such entitlement. 

 3. Data Privacy Notice. If the Participant resides and/or works in the United Kingdom, the
following provision replaces Section 8(t) of the Agreement: 
 The Company, with its principal office at 95 Morton St., 8th Floor,
New York, New York 10014, United States of America, is the controller responsible for the processing of the Participant’s personal data by the Company and the third parties noted below. 

(a) Data Collection, Processing and Usage. Pursuant to applicable data protection laws, the Participant is hereby notified that the
Company collects, processes and uses certain personal information about the Participant for the legitimate purpose of implementing, administering and managing the Plan and generally administering Options, specifically [the Participant’s name,
home address, email address and telephone number, date of birth, social security or insurance number, passport number or other identification number, salary, nationality, and any Shares or directorships held in the Company, and details of the
Options or any other entitlement to Shares, canceled, exercised, vested, unvested or outstanding in the Participant’s favor] (“Personal Data”). In granting Options under the Plan, the Company will collect, process, use,
disclose and transfer (collectively, “Processing”) Personal Data for purposes of implementing, administering and managing the Plan. The Company’s legal basis for the Processing of Personal Data is the Company’s legitimate
business interests of managing the Plan, administering Options and complying with its contractual and statutory obligations, as well as the necessity of the Processing for the Company to perform its contractual obligations under this Agreement and
the Plan. The Participant’s refusal to provide Personal Data would make it impossible for the Company to perform its contractual obligations and may affect the Participant’s ability to participate in the Plan. As such, by accepting the
Options, the Participant voluntarily acknowledges the Processing of his or her Personal Data as described herein. 
 (b) Outside Service
Providers. The Company and the Employer may transfer Personal Data to Fidelity Stock Plan Services, LLC and its affiliates, an independent service provider based in the United States of America (the “Plan Broker”), which assists
the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Participant’s Personal Data with another company that serves in a similar manner.
The Processing of Personal Data will take place through both electronic and non-electronic means. Personal Data will only be accessible by those individuals requiring access to it for purposes of implementing,
administering and operating the Plan. When receiving the Participant’s Personal Data, if applicable, the Plan Broker provides appropriate safeguards in accordance with the Standard Contractual Clauses or other appropriate cross-border transfer
solutions. By accepting the Options, the Participant understands that the Plan Broker will Process the Participant’s Personal Data for the purposes of implementing, administering and managing the Participant’s participation in the Plan.

 (c) International Personal Data Transfers. The Plan and Options are administered in
the United States of America, which means it will be necessary for Personal Data to be transferred to, and Processed in the United States of America. When transferring Personal Data to the United States of America, the Company provides appropriate
safeguards in accordance with the Standard Contractual Clauses or other appropriate cross-border transfer solutions. The Participant may request a copy of the appropriate safeguards with the Plan Broker or the Company by contacting [the
Participant’s human resources representative]. 
 (d) Data Retention. The Company will use the Participant’s personal data
only as long as is necessary to implement, administer and manage his or her participation in the Plan or as required to comply with legal or regulatory obligations, including under tax, exchange control, securities, and labor laws. When the Company
no longer needs Personal Data related to the Plan, the Company will remove it from its systems. If the Company keeps Personal Data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be for
compliance with Applicable Law. 
 (e) Data Subject Rights. To the extent provided by law, the Participant has the right to
(i) subject to certain exceptions, request access or copies of Personal Data the Company Processes, (ii) request rectification of incorrect Personal Data, (iii) request deletion of Personal Data, (iv) place restrictions on
Processing of Personal Data, (v) lodge complaints with competent authorities in the Participant’s country, and/or (vi) request a list with the names and addresses of any potential recipients of Personal Data. To receive clarification
regarding the Participant’s rights or to exercise the Participant’s rights, the Participant may contact [the Participant’s human resources representative]. The Participant also has the right to object, on grounds related to a
particular situation, to the Processing of Personal Data, as well as opt-out of the Plan, in any case without cost, by contacting [the Participant’s human resources representative] in writing. The
Participant’s provision of Personal Data is a contractual requirement. The Participant understands, however, that the only consequence of refusing to provide Personal Data is that the Company may not be able to administer the Options, or grant
other awards or administer or maintain such awards. For more information on the consequences of the refusal to provide Personal Data, the Participant may contact [the Participant’s human resources representative] in writing.

 Exhibit 10.4 

INTEGRAL AD SCIENCE HOLDING CORP. 
  

 
 2021 EMPLOYEE
STOCK PURCHASE PLAN 
  
  

ARTICLE I 
 PURPOSE

 The Plan’s purpose is to assist employees of the Company and its Designated Companies in acquiring a share ownership interest in
the Company, and to help such employees provide for their future security and to encourage them to remain in the employment of the Company and its Subsidiaries and Affiliates. 

The Plan consists of two components: the Section 423 Component and the Non-Section 423
Component. The Section 423 Component is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code and shall be administered, interpreted and construed in a manner consistent with the requirements of
Section 423 of the Code. In addition, the Plan authorizes the grant of Options under the Non-Section 423 Component, which need not qualify as Options granted pursuant to an “employee stock
purchase plan” under Section 423 of the Code; such Options granted under the Non-Section 423 Component shall be granted pursuant to separate Offerings containing such sub-plans, appendices, rules or procedures as may be adopted by the Administrator and designed to achieve tax, securities laws or other objectives for Eligible Employees and the Designated Companies
in locations outside of the United States. Except as otherwise provided herein or determined by the Administrator, the Non-Section 423 Component will operate and be administered in the same manner as
the Section 423 Component. Offerings intended to be made under the Non-Section 423 Component will be designated as such by the Administrator at or prior to the time of such Offering. 

For purposes of the Plan, the Administrator may designate separate Offerings under the Plan, the terms of which need not be identical, in
which Eligible Employees may participate, provided that the terms of participation are the same within each separate Offering under the Section 423 Component as determined under Section 423 of the Code. Solely by way of example and without
limiting the foregoing, the Company could, but shall not be required to, provide for simultaneous Offerings under the Section 423 Component and the Non-Section 423 Component of the Plan.

basis. Further, the Administrator will have discretion to determine the application of this definition to Eligible Employees outside the United States. 

 2.10 “Designated Company” means each Affiliate and
Subsidiary, including any Affiliate and Subsidiary in existence on the Effective Date and any Affiliate and Subsidiary formed or acquired following the Effective Date, that has been designated by the Administrator from time to time in its sole

or Non-Section 423 Component. A Designated Company may participate in either the Section 423 Component or Non-Section 423 Component, but not
both. Notwithstanding the foregoing, if any Affiliate or Subsidiary is disregarded for U.S. federal income tax purposes in respect of the Company or any Designated Company participating in the Section 423 Component, then such disregarded
Affiliate or Subsidiary shall automatically be a Designated Company participating in the Section 423 Component. If any Affiliate or Subsidiary is disregarded for U.S. federal income tax purposes in respect of any Designated Company

(B) compliance with the laws of the jurisdiction would cause the Section 423 Component, any Offering thereunder or an Option granted thereunder to violate the requirements of Section 423 of the Code; provided that any
exclusion shall be applied in an identical manner under each Offering to all Employees in accordance with Treas. Reg. § 1.423-2(e). 

 Notwithstanding the foregoing, any Employee who, after the granting of the Option, would be deemed for
purposes of Section 423(b)(3) of the Code to possess 5% or more of the total combined voting power or value of all classes of shares of the Company or any Subsidiary shall not be an Eligible Employee. For purposes of the preceding sentence, the
rules of Section 424(d) of the Code with regard to the attribution of share ownership shall apply in determining the share ownership of an individual, and shares which an Employee may purchase under outstanding options under the Plan shall be
treated as shares owned by the Employee. 
 Further, with respect to the Non-Section 423 Component,
(a) the Administrator may limit eligibility further within a Designated Company so as to only designate some Employees of a Designated Company as Eligible Employees, and (b) to the extent any restrictions in this definition are not
consistent with applicable local laws, the applicable local laws shall control. 
 2.13 “Employee” means any
person who renders services to the Company or a Designated Company in the status of an employee within the meaning of Section 3401(c) of the Code. “Employee” shall not include any director of the Company or a Designated Company who

the individual is on military leave, sick leave or other leave of absence approved by the Company or a Designated Company and meeting the requirements of Treas. Reg. § 1.421-1(h)(2). Where the
period of leave exceeds three months, or such other period specified in Treas. Reg. § 1.421-1(h)(2), and the individual’s right to reemployment is not guaranteed either by statute or by
contract, the employment relationship shall be deemed to have terminated on the first day immediately following such three (3)-month period, or such other period specified in Treas. Reg.

low asked prices for a Share on such date, the high bid and low asked prices for a Share on the last preceding date for which such information exists, as reported in The Wall Street Journal or such other source as the Administrator

the Section 423 Component need not be identical, provided that the terms of the Section 423 Component and an Offering thereunder together satisfy Treas. Reg. § 1.423-2(a)(2) and

PARTICIPATION 
 3.1
Eligibility. 
 (a) Any Eligible Employee who is employed by the Company or a Designated Company on a given Enrollment Date
for an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of Articles 4 and 5 hereof, and, for the Section 423 Component, the limitations imposed by Section 423(b) of the
Code. 
 (b) No Eligible Employee shall be granted an Option under the Section 423 Component which permits the Participant to purchase
Shares under the Plan, and to purchase shares under all other employee stock purchase plans of the Company, any Parent or any Subsidiary subject to Section 423 of the Code, at a rate which exceeds USD 25,000 of fair market value of such
shares (determined at the time such Option is granted) for each calendar year in which such Option is outstanding at any time. The limitation under this Section 3.1(b) shall be applied in accordance with Section 423(b)(8) of the Code. 

3.2 Election to Participate; Payroll Deductions. 

(a) Each individual who is an Eligible Employee as of an Offering Period’s Enrollment Date may elect to participate in such Offering
Period and the Plan by delivering to the Company or an Agent designated by the Company an enrollment form including a payroll deduction authorization (which may be in an electronic format or such other method as determined by the Company in
accordance with the Company’s practices) (a “Participation Election”) no later than the period of time prior to the applicable Enrollment Date determined by the Administrator, in its sole discretion. Except as provided
in Section 3.2(e) hereof, an Eligible Employee may participate in the Plan only by means of payroll deduction. 
 (b) Subject to
Section 3.1(b) hereof and except as may otherwise be determined by the Administrator, payroll deductions (i) shall equal at least 1% of the Participant’s Compensation as of each Payday of the Offering Period following the Enrollment
Date, but not more than 15% of the Participant’s Compensation as of each Payday of the Offering Period following the Enrollment Date; and (ii) shall be expressed as a whole number percentage. Subject to Section 3.2(e)
hereof, amounts deducted from a Participant’s Compensation with respect to an Offering Period pursuant to this Section 3.2 shall be deducted each Payday through payroll deduction and credited to the Participant’s Plan Account. 

(c) Unless otherwise determined by the Administrator, following at least one payroll deduction, a Participant may increase or decrease the
percentage of Compensation designated in his or her enrollment form, subject to the limits of this Section 3.2, or may suspend his or her payroll deductions, at any time during an Offering Period; provided, however, that the
Administrator may limit the number of changes a Participant may make to his or her payroll deduction elections during each Offering Period in the applicable Offering (and in the absence of any specific designation by the Administrator, a Participant
shall only be allowed to decrease his or her payroll deduction election one time during each Offering Period and shall not be permitted to increase his or her payroll deduction at any time during an Offering Period). Any such change or suspension of
payroll deductions shall be effective with the first full payroll period following ten business days after the Company’s receipt of the new enrollment form (or such shorter or longer period as may be specified by the Administrator in the
applicable Offering). In the event a 

 
Participant suspends his or her payroll deductions, such Participant’s cumulative payroll deductions prior to the suspension shall remain in his or her account and shall be applied to the
purchase of Shares on the next occurring Exercise Date and shall not be paid to such Participant unless he or she withdraws from participation in the Plan pursuant to Section 6.1. 

(d) Upon the completion of an Offering Period, each Participant in such Offering Period shall automatically participate in the immediately
following Offering Period at the same payroll deduction percentage as in effect at the termination of such Offering Period, unless such Participant delivers to the Company or an Agent designated by the Company a different Participation Election with
respect to the successive Offering Period in accordance with Section 3.2(a) hereof, or unless such Participant becomes ineligible for participation in the Plan. 

(e) Notwithstanding any other provisions of the Plan to the contrary,
in non-U.S. jurisdictions where participation in the Plan through payroll deductions is prohibited or otherwise problematic under applicable local laws (as determined by the Administrator in its sole
discretion), the Administrator may provide that an Eligible Employee may elect to participate through contributions to the Participant’s Plan Account in a form acceptable to the Administrator in lieu of or in addition to payroll deductions;
provided, however, that, for any Offering under the Section 423 Component, the Administrator must determine that any alternative method of contribution is applied on an equal and uniform basis to all Eligible Employees in the Offering. Any
reference to “payroll deductions” in this Section 3.2 (or in any other section of the Plan) will similarly cover contributions by other means made pursuant to this Section 3.2(e). 

ARTICLE IV 
 PURCHASE OF
SHARES 
 4.1 Grant of Option. The Company may make one or more Offerings under the Plan, which may be successive
or overlapping with one another, until the earlier of: (i) the date on which all Shares available under the Plan have been purchased or (ii) the date on which the Plan is suspended or terminates. No Offering shall commence prior to the
date on which the Company’s registration statement on Form S-8 is filed with the U.S. Securities and Exchange Commission in respect of the Plan. The Administrator shall designate the terms and
conditions of each Offering in writing, including without limitation, the Offering Period and the Purchase Periods. Each Participant shall be granted an Option with respect to an Offering Period on the applicable Grant Date. Subject to the
limitations of Section 3.1(b) hereof, the number of Shares subject to a Participant’s Option shall be determined by dividing (a) such Participant’s payroll deductions accumulated prior to an Exercise Date and retained in the
Participant’s Plan Account on such Exercise Date by (b) the applicable Option Price; provided that in no event shall a Participant be permitted to purchase during each Offering Period more than 2,500 shares of Common Stock (subject to any
adjustment pursuant to Section 5.2 hereof). The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of Shares that a Participant may purchase during any Purchase Periods under
such future Offering Periods. Each Option shall expire on the last Exercise Date for the applicable Offering Period immediately after the automatic exercise of the Option in accordance with Section 4.3 hereof, unless such Option terminates
earlier in accordance with Article 6 hereof. 

 4.2 Option Price. The Option Price shall equal 85% of the lesser of the
Fair Market Value of a Share on (a) the applicable Grant Date and (b) the applicable Exercise Date, or such other price designated by the Administrator. 

4.3 Purchase of Shares. 

(a) On each Exercise Date for an Offering Period, each Participant shall automatically and without any action on such Participant’s part
be deemed to have exercised the Participant’s Option to purchase at the applicable Option Price the largest number of whole Shares which can be purchased with the amount in the Participant’s Plan Account, subject to the limitations set
forth in the Plan. Unless otherwise determined by the Administrator in advance of an Offering or in accordance with applicable law, any balance that is remaining in the Participant’s Plan Account (after exercise of such Participant’s
Option) as of the Exercise Date shall be carried forward into the next Offering Period, unless the Participant has properly elected to withdraw from the Plan, has ceased to be an Eligible Employee or with respect to the maximum limitations set forth
in Section 3.1(b) and Section 4.1. Any balance not carried forward to the next Offering Period in accordance with the prior sentence shall promptly be refunded as soon as administratively practicable to the applicable Participant. 

(b) As soon as practicable following each Exercise Date, the number of Shares purchased by such Participant pursuant to Section 4.3(a)
hereof shall be delivered (either in share certificate or book entry form), in the Company’s sole discretion, to either (i) the Participant or (ii) an account established in the Participant’s name at a stock brokerage or other
financial services firm designated by the Company. The Company may require that shares be retained with such brokerage or firm for a designated period of time and/or may establish procedures to permit tracking of disqualifying dispositions of such
shares. 
 4.4 Transferability of Rights. An Option granted under the Plan shall not be transferable, other than by
will or the applicable laws of descent and distribution, and is exercisable during the Participant’s lifetime only by the Participant. No option or interest or right to the Option shall be available to pay off any debts, contracts or
engagements of the Participant or the Participant’s successors in interest or shall be subject to disposition by pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempt at disposition of the Option shall have no effect. 

ARTICLE V 
 PROVISIONS
RELATING TO COMMON STOCK 
 5.1 Shares Reserved. Subject to adjustment as provided in Section 5.2 hereof, the
aggregate number of Shares that may be issued pursuant to rights granted under the Plan shall be the sum of (a) 1,489,571 Shares and (b) an annual increase on the first day of each year beginning on January 1, 2022 and annually thereafter
ending in 2031 equal to the lesser of (i) 1% of all classes of the Company’s shares outstanding on the last day of the immediately preceding calendar year and (ii) such smaller number of shares as may be determined by the Board;
provided, however, no more than 16,000,000 Shares may be issued in total under the 423 Component of the Plan. Shares made available for sale under the Plan may be authorized but unissued shares or treasury Shares. If any right granted under
the Plan shall for any reason terminate without having been exercised, the Shares not purchased under such right shall again become available for issuance under the Plan. 

 5.2 Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
Merger or Asset Sale. 
 (a) Changes in Capitalization. Subject to any required action by the shareholders of the Company,
the number of Shares which have been authorized for issuance under the Plan but not yet placed under Option, as well as the price per share and the number of Shares covered by each Option under the Plan which has not yet been exercised shall be
proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a share split, reverse share split, share dividend, combination, amalgamation, consolidation, reorganization, arrangement or reclassification of the
Shares, or any other increase or decrease in the number Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to
have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of any class, or securities convertible into shares of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Offering Periods then in
progress shall be shortened by setting a new Exercise Date (the “New Exercise Date”), and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the
Administrator. The New Exercise Date shall be before the date of the Company’s proposed dissolution or liquidation. The Administrator shall notify each Participant in writing, at least ten business days prior to the New Exercise Date, that
the Exercise Date for the Participant’s Option has been changed to the New Exercise Date and that the Participant’s Option shall be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn
from the Offering Period as provided in Section 6.1 hereof or the Participant has ceased to be an Eligible Employee as provided in Section 6.2 hereof. 

(c) Merger or Asset Sale. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of
the Company with or into another corporation, each outstanding Option shall be assumed or an equivalent Option substituted by the successor corporation or a parent or subsidiary of the successor corporation. If the successor corporation refuses to
assume or substitute for the Option, any Offering Periods then in progress shall be shortened by setting a New Exercise Date and any Offering Periods then in progress shall end on the New Exercise Date. The New Exercise Date shall be before the date
of the Company’s proposed sale or merger. The Administrator shall notify each Participant in writing, at least ten business days prior to the New Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the
New Exercise Date and that the Participant’s Option shall be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 6.1 hereof or the
Participant has ceased to be an Eligible Employee as provided in Section 6.2 hereof. 

 5.3 Insufficient Shares. If the Administrator determines that, on a
given Exercise Date, the number of Shares with respect to which Options are to be exercised may exceed the number of Shares remaining available for sale under the Plan on such Exercise Date, the Administrator shall make a pro rata allocation of the
Shares available for issuance on such Exercise Date in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants exercising Options to purchase Shares on such Exercise Date,
and unless additional shares are authorized for issuance under the Plan, no further Offering Periods shall take place and the Plan shall terminate pursuant to Section 7.5 hereof. If an Offering Period is so terminated, then the balance of the
amount credited to the Participant’s Plan Account which has not been applied to the purchase of Shares shall be paid to such Participant in one lump sum in cash within 30 days after such Exercise Date, without any interest thereon (except as
may be required by applicable local laws). 
 5.4 Rights as Shareholders. With respect to Shares subject to an Option,
a Participant shall not be deemed to be a shareholder of the Company and shall not have any of the rights or privileges of a shareholder. A Participant shall have the rights and privileges of a shareholder of the Company when, but not until, the
Shares have been deposited in the designated brokerage account following exercise of the Participant’s Option. 
 ARTICLE VI 

TERMINATION OF PARTICIPATION 

6.1 Cessation of Contributions; Voluntary Withdrawal. 

(a) A Participant may cease payroll deductions during an Offering Period and elect to withdraw from the Plan by delivering written notice of
such election to the Company or an Agent designated by the Company in such form and at such time prior to the Exercise Date for such Offering Period as may be established by the Administrator (a “Withdrawal Election”). In the
event a Participant elects to withdraw from the Plan, amounts then credited to such Participant’s Plan Account shall be returned to the Participant in one lump-sum payment in cash within 30 days
after such election is received by the Company, without any interest thereon (except as may be required by applicable local laws), and the Participant shall cease to participate in the Plan and the Participant’s Option for such Offering Period
shall terminate upon receipt of the Withdrawal Election.  
 (b) A Participant’s withdrawal from the Plan shall not have
any effect upon the Participant’s eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods which commence after the termination of the Offering Period from which the
Participant withdraws. 
 (c) A Participant who ceases contributions to the Plan during any Offering Period shall not be permitted to resume
contributions to the Plan during that Offering Period. 

 6.2 Termination of Eligibility. Upon a Participant’s ceasing to be
an Eligible Employee, for any reason, such Participant’s Option for the applicable Offering Period shall automatically terminate, the Participant shall be deemed to have elected to withdraw from the Plan, and any balance on such
Participant’s Plan Account shall be paid to such Participant or, in the case of the Participant’s death, to the person or persons entitled thereto pursuant to applicable law, within 30 days after such cessation of being an Eligible
Employee, without any interest thereon (except as may be required by applicable local laws). If a Participant transfers employment from the Company or any Designated Company participating in the Section 423 Component to any Designated Company
participating in the Non-Section 423 Component, such transfer shall not be treated as a termination of employment, but the Participant shall immediately cease to participate in the Section 423
Component; however, any contributions made for the Offering Period in which such transfer occurs shall be transferred to the Non-Section 423 Component, and such Participant shall immediately join the
then-current Offering under the Non-Section 423 Component upon the same terms and conditions in effect for the Participant’s participation in the Section 423 Component, except for such
modifications otherwise applicable for Participants in such Offering. A Participant who transfers employment from any Designated Company participating in the Non-Section 423 Component to the Company
or any Designated Company participating in the Section 423 Component shall not be treated as terminating the Participant’s employment and shall remain a Participant in the Non-Section 423
Component until the earlier of (i) the end of the current Offering Period under the Non-Section 423 Component, or (ii) the Enrollment Date of the first Offering Period in which the
Participant is eligible to participate following such transfer. Notwithstanding the foregoing, the Administrator may establish different rules to govern transfers of employment between companies participating in the Section 423 Component and the Non-Section 423 Component, consistent with the applicable requirements of Section 423 of the Code. 

ARTICLE VII 
 GENERAL
PROVISIONS 
 7.1 Administration. 

(a) The Plan shall be administered by the Committee, which shall be composed of members of the Board. The Committee may delegate
administrative tasks under the Plan to the services of an Agent or Employees to assist in the administration of the Plan, including without limitation, determining the Designated Companies participating in the Plan, establishing and maintaining an
individual securities account under the Plan for each Participant, determining enrollment and withdrawal deadlines and determining exchange rates. In its absolute discretion, the Board may at any time and from time to time exercise any and all
rights and duties of the Administrator under the Plan. 
 (b) It shall be the duty of the Administrator to conduct the general
administration of the Plan in accordance with the provisions of the Plan. The Administrator shall have the power, subject to, and within the limitations of, the express provisions of the Plan: 

(i) To establish and terminate Offerings; 

(ii) To determine when and how Options shall be granted and the provisions and terms of each Offering (which need not be
identical); 

 (iii) To select Designated Companies in accordance with Section 7.2
hereof; and 
 (iv) To construe and interpret the Plan, the terms of any Offering and the terms of the Options and to adopt
such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret, amend or revoke any such rules. The Administrator, in the exercise of this power, may correct any defect, omission or
inconsistency in the Plan, any Offering or any Option, in a manner and to the extent it shall deem necessary or expedient to administer the Plan, subject to Section 423 of the Code for the Section 423 Component. 

(c) The Administrator may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific
requirements of local laws and procedures, provided that the adoption and implementation of any such rules and/or procedures would not cause the Section 423 Component to be in noncompliance with Section 423 of the Code. Without
limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding handling of participation elections, payroll deductions, payment of interest, conversion of local currency, payroll tax,
withholding procedures and handling of share certificates which vary with local requirements. 
 (d) The Administrator may adopt sub-plans applicable to particular Designated Companies or locations, which sub-plans may be designed to be outside the scope of Section 423 of
the Code. The rules of such sub-plans may take precedence over other provisions of the Plan, with the exception of Section 5.1 hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of the Plan shall govern the operation of such sub-plan. 

(e) All expenses and liabilities incurred by the Administrator in connection with the administration of the Plan shall be borne by the
Company. The Administrator may employ attorneys, consultants, accountants, appraisers, brokers or other persons. The Administrator, the Company and its officers and directors shall be entitled to rely upon the advice, opinions or valuations of any
such persons. All actions taken and all interpretations and determinations made by the Administrator in good faith shall be final and binding upon all Participants, the Company and all other interested persons. No member of the Board or
Administrator shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or the Options, and all members of the Board or Administrator shall be fully protected by the Company in respect to
any such action, determination, or interpretation. Any and all risks resulting from any market fluctuations or conditions of any nature and affecting the price of Shares are assumed by the Participant. 

7.2 Designation of Affiliates and Subsidiaries. The Administrator shall designate from time to time the Affiliates and
Subsidiaries that shall constitute Designated Companies, and determine whether such Designated Companies shall participate in the Section 423 Component or Non-Section 423
Component; provided, however, that an Affiliate that does not also qualify as a Subsidiary may be designated only as participating in the Non-Section 423 Component. The Administrator may
designate an Affiliate or Subsidiary, or terminate the designation of an Affiliate or Subsidiary, without the approval of the shareholders of the Company. 

 7.3 Reports. Individual accounts shall be maintained for each
Participant in the Plan. Statements of Plan Accounts shall be given to Participants at least annually, which statements shall set forth the amounts of payroll deductions, the Option Price, the number of shares purchased and the remaining cash
balance, if any. 
 7.4 No Right to Employment. Nothing in the Plan shall be construed to give any person (including
any Participant) the right to remain in the employ of the Company, a Parent, a Subsidiary or an Affiliate or to affect the right of the Company, any Parent, any Subsidiary or any Affiliate to terminate the employment of any person (including any
Participant) at any time, with or without cause, which right is expressly reserved. 
 7.5 Amendment and Termination of the
Plan. 
 (a) The Board may, in its sole discretion, amend, suspend or terminate the Plan at any time and from time to time. To the
extent necessary to comply with Section 423 of the Code (or any successor rule or provision), with respect to the Section 423 Component, or any other applicable law, regulation or stock exchange rule, the Company shall obtain shareholder
approval of any such amendment to the Plan in such a manner and to such a degree as required by Section 423 of the Code or such other law, regulation or rule. 

(b) If the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the
Administrator may in its discretion modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to: 

(i) altering the Option Price for any Offering Period including an Offering Period underway at the time of the change in Option
Price; 
 (ii) shortening any Offering Period so that the Offering Period ends on a new Exercise Date, including an Offering
Period underway at the time of the Administrator action; and 
 (iii) allocating Shares. 

Such modifications or amendments shall not require shareholder approval or the consent of any Participant. 

(c) Upon termination of the Plan, the balance in each Participant’s Plan Account shall be refunded as soon as practicable after such
termination, without any interest thereon (except as may be required by applicable local laws). 
 7.6 Use of Funds; No
Interest Paid. All funds received by the Company by reason of purchase of shares of Shares under the Plan shall be included in the general funds of the Company free of any trust or other restriction and may be used for any corporate purpose
(except as may be required by applicable local laws). No interest shall be paid to any Participant or credited under the Plan (except as may be required by applicable local laws). 

 7.7 Term; Approval by Shareholders. No Option may be granted during any
period of suspension of the Plan or after termination of the Plan. The Plan shall be submitted for the approval of the Company’s shareholders within 12 months after the date of the Board’s initial adoption of the Plan. Options may be
granted prior to such shareholder approval; provided, however, that such Options shall not be exercisable prior to the time when the Plan is approved by the shareholders; provided, further that if
such approval has not been obtained by the end of the 12-month period, all Options previously granted under the Plan shall thereupon terminate and be canceled and become null and void without being
exercised. 
 7.8 Effect Upon Other Plans. The adoption of the Plan shall not affect any other compensation or
incentive plans in effect for the Company, any Parent, any Subsidiary or any Affiliate. Nothing in the Plan shall be construed to limit the right of the Company, any Parent, any Subsidiary or any Affiliate (a) to establish any other forms of
incentives or compensation for employees of the Company or any Parent, any Subsidiary or any Affiliate, or (b) to grant or assume Options other than under the Plan in connection with any proper corporate purpose, including, but not by way of
limitation, the grant or assumption of options in connection with the acquisition, by purchase, lease, merger, amalgamation, combination, arrangement, consolidation or otherwise, of the business, shares or assets of any corporation, firm or
association. 
 7.9 Conformity to Securities Laws. Notwithstanding any other provision of the Plan, the Plan and the
participation in the Plan by any individual who is then subject to Section 16 of the Exchange Act shall be subject to any additional limitations set forth in any applicable exemption rule under Section 16 of the Exchange Act (including any
amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by applicable law, the Plan shall be deemed amended to the
extent necessary to conform to such applicable exemptive rule. 
 7.10 Notice of Disposition of Shares. Each
Participant shall give the Company prompt notice of any disposition or other transfer of any Shares, acquired pursuant to the exercise of an Option granted under the Section 423 Component, if such disposition or transfer is made (a) within
two years after the applicable Grant Date or (b) within one year after the transfer of such Shares to such Participant upon exercise of such Option. The Company may direct that any certificates evidencing shares acquired pursuant to the Plan
refer to such requirement. 
 7.11 Tax Withholding. At the time of any taxable event that creates a withholding
obligation for the Company or any Parent, Affiliate or Subsidiary, the Participant will make adequate provision for any Tax-Related Items. In their sole discretion, and except as otherwise determined
by the Administrator, the Company or the Designated Company that employs or employed the Participant may satisfy their obligations to withhold Tax-Related Items by (a) withholding from the
Participant’s wages or other compensation, (b) withholding a sufficient whole number of Shares otherwise issuable following exercise of the Option having an aggregate value sufficient to pay
the Tax-Related Items required to be withheld with respect to the Option and/or shares, or (c) withholding from proceeds from the sale of Shares issued upon exercise of the Option, either
through a voluntary sale or a mandatory sale arranged by the Company, or (d) any other method determined by the Administrator to be in compliance with applicable laws. 

 7.12 Governing Law. The Plan and all rights, agreements and obligations
hereunder shall be administered, interpreted and enforced under the laws of the State of Delaware, without regard to the conflict of law rules thereof or of any other jurisdiction. 

7.13 Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan
shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

7.14 Conditions to Issuance of Shares. 

(a) Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates or make any book
entries evidencing Shares pursuant to the exercise of an Option by a Participant, unless and until the Administrator has determined, with advice of counsel, that the issuance of such Shares is in compliance with all applicable laws, regulations of
governmental authorities and, if applicable, the requirements of any securities exchange or automated quotation system on which the Shares are listed or traded, and the Shares are covered by an effective registration statement or applicable
exemption from registration. In addition to the terms and conditions provided herein, the Administrator may require that a Participant make such reasonable covenants, agreements, and representations as the Administrator, in its discretion, deems
advisable in order to comply with any such laws, regulations, or requirements. 
 (b) All certificates for Shares delivered pursuant to the
Plan and all Shares issued pursuant to book entry procedures are subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with U.S.
and non-U.S. federal, provincial, state or local securities or other laws, rules and regulations and the rules of any securities exchange or automated quotation system on which the Shares are listed,
quoted, or traded. The Administrator may place legends on any certificate or book entry evidencing Shares to reference restrictions applicable to the Shares. 

(c) The Administrator shall have the right to require any Participant to comply with any timing or other restrictions with respect to the
settlement, distribution or exercise of any Option, including a window-period limitation, as may be imposed in the sole discretion of the Administrator. 

(d) Notwithstanding any other provision of the Plan, unless otherwise determined by the Administrator or required by any applicable law, rule
or regulation, the Company may, in lieu of delivering to any Participant certificates evidencing Shares issued in connection with any Option, record the issuance of Shares in the books of the Company (or, as applicable, its transfer agent or share
plan administrator). 
 If, pursuant to this Section 7.14, the Administrator determines that Shares will not be issued to any Participant, the Company
is relieved from liability to any Participant except to refund to the Participant such Participant’s Plan Account balance, without interest thereon (except as may be required by applicable local laws). 

 7.15 Equal Rights and Privileges. All Eligible Employees granted
Options pursuant to an Offering under the Section 423 Component shall have equal rights and privileges under the Plan to the extent required under Section 423 of the Code so that the Section 423 Component qualifies as an
“employee stock purchase plan” within the meaning of Section 423 of the Code. Any provision of the Section 423 Component that is inconsistent with Section 423 of the Code shall, without further act or amendment by the
Company or the Board, be reformed to comply with the equal rights and privileges requirement of Section 423 of the Code. Eligible Employees participating in the Non-Section 423 Component need
not have the same rights and privileges as each other, or as Eligible Employees participating in the Section 423 Component. 

7.16 Rules Particular to Specific Countries. Notwithstanding anything herein to the contrary, the terms and conditions of
the Plan with respect to Participants who are tax residents of a particular non-U.S. country or who are non-U.S. nationals or employed in non-U.S. jurisdictions may be subject to an addendum to the Plan in the form of an appendix or sub-plan (which appendix
or sub-plan may be designed to govern Offerings under the Section 423 Component or the Non-Section 423 Component, as determined by the
Administrator). To the extent that the terms and conditions set forth in an appendix or sub-plan conflict with any provisions of the Plan, the provisions of the appendix or sub-plan shall govern. The adoption of any such appendix or sub-plan shall be pursuant to Section 7.1 above. Without limiting the foregoing, the
Administrator is specifically authorized to adopt rules and procedures, with respect to Participants who are non-U.S. nationals or employed
in non-U.S. jurisdictions, regarding the exclusion of particular Affiliates or Subsidiaries from participation in the Plan, eligibility to participate, the definition of Compensation, handling of
payroll deductions or other contributions by Participants, payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures, establishment of bank or trust accounts to hold payroll deductions or
contributions, provided that the adoption and implementation of any such rules and/or procedures would not cause the Section 423 Component to be in noncompliance with Section 423 of the Code. 

7.17 Section 409A. The Section 423 Component of the Plan and the Options granted pursuant to Offerings thereunder
are intended to be exempt from the application of Section 409A. Neither the Non-Section 423 Component nor any Option granted pursuant to an Offering thereunder is intended to constitute or
provide for “nonqualified deferred compensation” within the meaning of Section 409A. Notwithstanding any provision of the Plan to the contrary, if the Administrator determines that any Option granted under the Plan may be or become
subject to Section 409A or that any provision of the Plan may cause an Option granted under the Plan to be or become subject to Section 409A, the Administrator may adopt such amendments to the Plan and/or adopt other policies and
procedures (including amendments, policies and procedures with retroactive effect), or take any other actions as the Administrator determines are necessary or appropriate to avoid the imposition of taxes under Section 409A, either through
compliance with the requirements of Section 409A or through an available exemption therefrom.
