PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13. Other Expenses of Issuance and Distribution.

The following table sets forth all costs and expenses, other than the underwriting discounts and commissions payable by us, in connection with the offer and sale of the securities being registered. All amounts shown are estimates except for the Securities and Exchange Commission, or SEC, registration fee and the FINRA filing fee.

Item 14. Indemnification of Directors and Officers.

Section 102(b)(7) of the DGCL allows a corporation to provide in its certificate of incorporation that a director of the corporation will not be personally liable to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except where the director breached the duty of loyalty, failed to act in good faith, engaged in intentional misconduct, or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our certificate of incorporation will provide for this limitation of liability.

Section 145 of the DGCL, or Section 145, provides that a Delaware corporation may indemnify any person who was, is or is threatened to be made, party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. A Delaware corporation may indemnify any persons who are, were or are a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person is or was a director, officer, employee, or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, provided that no indemnification is permitted without judicial approval if the officer, director, employee, or agent is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred.

II-1

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145.

Our bylaws will provide that we will indemnify our directors and officers to the fullest extent authorized by the DGCL and must also pay expenses incurred in defending any such proceeding in advance of its final disposition upon delivery of an undertaking, by or on behalf of an indemnified person, to repay all amounts so advanced if it should be determined ultimately that such person is not entitled to be indemnified under this section or otherwise.

Upon completion of this offering we intend to enter into indemnification agreements with each of our executive officers and directors. The indemnification agreements will provide the executive officers and directors with contractual rights to indemnification, expense advancement, and reimbursement, to the fullest extent permitted under the DGCL.

The indemnification rights set forth above shall not be exclusive of any other right which an indemnified person may have or hereafter acquire under any statute, provision of our certificate of incorporation or bylaws, agreement, vote of shareholders ,or disinterested directors or otherwise.

We will maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers. The proposed form of Underwriting Agreement to be filed as Exhibit 1.1 to this Registration Statement provides for indemnification of our directors and officers by the underwriters party thereto against certain liabilities arising under the Securities Act or otherwise.

Item 15. Recent Sales of Unregistered Securities.

Set forth below is information regarding securities sold by us within the past three years that were not registered under the Securities Act. Also included is the consideration, if any, received by us for such securities and information relating to the section of the Securities Act, or rule of the SEC, under which exemption from registration was claimed.

Since January 1, 2018, we have made sales of the following unregistered securities:

II-2

The offers and sales of the above securities were deemed to be exempt from registration under the Securities Act in reliance upon Section 4(a)(2) of the Securities Act or Regulation D promulgated thereunder, or Rule 701 promulgated under Section 3(b) of the Securities Act, as transactions by an issuer not involving any public offering or pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of the above securities represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof. Appropriate legends were placed upon any stock certificates issued in these transactions.

Item 16. Exhibits and Financial Statement Schedules.

(i) Exhibits

II-3

No financial statement schedules are provided because the information called for is not applicable or is shown in the financial statements or notes.

Item 17. Undertakings.

The undersigned registrant hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referenced in Item 14 of this Registration Statement, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in the form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective;

(2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof.

II-4

(b) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, to furnish to the Representatives a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Representatives reasonably object, and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule.

(c) To furnish to the Representatives a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which the Representatives reasonably object.

(d) Not to take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder.

(e) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(f) If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or

supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses the Representatives will furnish to the Company) to which Shares may have been sold by the Representatives on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

(g) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request; provided, however, that nothing contained herein shall require the Company to qualify to do business in any jurisdiction, to execute or file a general consent to service of process in any jurisdiction or to subject itself to taxation in any jurisdiction in which it is not otherwise subject.

(h) To make generally available to the Company’s security holders and to the Representatives as soon as practicable an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

[The provisions of this Section shall not supersede or otherwise affect any agreement that the Sellers may otherwise have for the allocation of such expenses among themselves.]

9. Covenants of the Underwriters. Each Underwriter, severally and not jointly, covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

10. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, its directors, officers and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter participating in the offering within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), the Prospectus or any amendment or supplement thereto, or any Testing-the-Waters Communication or arise out of, or are based upon, any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any such untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriters through the Representatives consists of the information described as such in paragraph (c) below. The Company agrees and confirms that references to “affiliates” of Morgan Stanley that appear in this Agreement shall be understood to include Mitsubishi UFJ Morgan Stanley Securities Co., Ltd.

(b) [The Selling Shareholders, jointly and severally, agree to indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Testing-the-Waters Communication or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Testing-the-Waters Communication, any Issuer Free Writing Prospectus or the Prospectus or any amendment or supplement thereto in reliance upon and in conformity with any Selling Shareholder Information furnished to the Company in writing by such Selling Shareholder expressly for the use therein; and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the liability of each Selling Shareholder pursuant to this subsection (b) shall not exceed the proceeds (net of any underwriting discounts and commissions but before deducting expenses) from the sale of the Shares sold by such Selling Shareholder hereunder.]

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Selling Shareholders, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any Selling Shareholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriters, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show, or the Prospectus or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the following information under the caption “Underwriters” in the Time of Sale Prospectus and the Prospectus: [the concession and reallowance figures in the [•] paragraph, the information regarding sales to discretionary accounts in the [•] paragraph, the information regarding stabilization and short positions in the [•] paragraph and the information regarding internet distributions in the [•] paragraph (the “Underwriter Information”)].

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11(a), 11(b) or 11(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable and documented fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i)the indemnifying party and the indemnified party shall have mutually agreed in writing to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or one party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the other party or (iii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholders and all persons, if any, who control any Selling Shareholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. [In the case of any such separate firm for the Selling Shareholders and such control persons of any Selling Shareholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Shareholders under the Powers of Attorney.] The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees

and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(e) To the extent the indemnification provided for in Section 11(a), 11(b) or 11(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i)in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii)if the allocation provided by clause 11(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 11(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by [the Company] [the Sellers] on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by [the Company] [each Seller] and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of [the Company] [the Sellers] on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Sellers or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 11 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(f) The Sellers and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company and the Selling Shareholders contained in this Agreement shall remain operative and in full force and effect regardless of (i)any termination of this Agreement, (ii)any investigation made by or on behalf of any Underwriter, the directors, officers, employees and agents of each Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, by or on behalf of any Selling Shareholder or any person controlling any Selling Shareholder, or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii)acceptance of and payment for any of the Shares.

11. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to or on the Closing Date or any Option Closing Date, as the case may be, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE American, the Nasdaq Global Select Market, the Nasdaq Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

12. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 14 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representatives, the Company [and the Selling Shareholders] for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company [or the Selling Shareholders]. In any such case either the Representatives or the [Company] [relevant Sellers] shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of [the Company] [any Seller] to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason [the Company] [any Seller] shall be unable to perform its obligations under this Agreement, the [Company] [Sellers] will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

13. Entire Agreement. (a)This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the [Selling Shareholders, on the one hand, and the] Underwriters[, on the other,] with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company [and each Selling Shareholder] acknowledge that in connection with the offering of the Shares: (i)the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company[, any of the Selling Shareholders] or any other person, (ii)the Underwriters owe the Company [and each Selling Shareholder] only those duties and obligations set forth in this Agreement, any contemporaneous written agreements and prior written agreements (to the extent not superseded by this Agreement), if any, (iii)the Underwriters may have interests that differ from those of the Company [and each Selling Shareholder,] and (iv) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person. The Company [and each Selling Shareholder] waive to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

(c) [Each Selling Shareholder further acknowledges and agrees that, although the Underwriters may provide certain Selling Shareholders with certain Regulation Best Interest and Form CRS disclosures or other related documentation in connection with the offering, the Underwriters are not making a recommendation to any Selling Shareholder to participate in the offering or sell any Shares at the Purchase Price, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.]

14. Recognition of the U.S. Special Resolution Regimes. (a)In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

15. Counterparts.

Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

16. Applicable Law. This Agreement, and any claim, controversy or dispute arising under or related to this Agreement, shall be governed by and construed in accordance with the internal laws of the State of New York. The Company irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York over any suit, action or proceeding arising out of or relating to this Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement or the offering of the Shares (each, a “Related Proceeding”). The Company irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any Related Proceeding brought in such a court and any claim that any such Related Proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

Ladies and Gentlemen:

The undersigned understands that Morgan Stanley & Co. LLC, Jefferies LLC and Barclays Capital Inc. (the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Integral Ad Science Holding Corp., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters, including Morgan Stanley (the “Underwriters”), of [●] shares (the “Shares”) of the common stock, par value $0.001 per share, of the Company (the “Common Stock”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Morgan Stanley on behalf of the Underwriters, it will not, and will not publicly disclose an intention to, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus (the “Restricted Period”) relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock (“Lock-Up Securities”) or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common

A-1

Stock or such other securities, in cash or otherwise. The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition of any Lock-Up Securities, even if any such sale or disposition transaction or transactions would be made or executed by or on behalf of someone other than the undersigned. The foregoing shall not apply to (a) transactions relating to shares of Common Stock acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Common Stock acquired in such open market transactions, (b) transfers of shares of Lock-Up Securities (i) as a bona fide gift, (ii) to any immediate family member of the undersigned, or any of its affiliates, or any trust for the direct or indirect benefit of the undersigned, or any of its affiliates (for the purposes of this agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin), (iii) to a corporation, partnership, limited liability company, trust or other entity of which the undersigned, or any of its affiliates, and the immediate family of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests, or (iv) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iii) above or (c) transfers of Lock-Up Securities to (i) a partner, member or stockholder, as the case may be, of such partnership, limited liability company or corporation, (ii) any wholly-owned subsidiary of the undersigned, (iii) an affiliate (as such term is defined in Rule 405 of the Securities Act of 1933, as amended) of the undersigned or (iv) if a transferee referred to in clauses (i) through (iii) above is not a natural person, any direct or indirect partner, member or shareholder of such transferee until the Lock-Up Securities come to be held by a natural person; provided that in the case of any transfer pursuant to clause (b)(i), (b)(ii), or (b)(iv) (to the extent the transfer is to a transferee referred to in (b)(i) or (b)(ii), each donee or transferee shall sign and deliver a lock-up agreement substantially in the form of this agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Restricted Period (other than a filing on a Form 5 that shall clearly indicate in the footnotes thereto the nature and conditions of such transfer, that such transfer is not for value and that the Lock-Up Securities subject to such transfer remain subject to restrictions set forth herein), provided further that in the case of any transfer or distribution pursuant to clause (b)(iii), (b)(iv) (to the extent the transfer is to a transferee referred to in (b)(iii)) or (c), (i) each transferee or distributee shall sign and deliver a lock-up agreement substantially in the form of this agreement, provided that with respect to any related series of transfers or distributions to transferees or distributees otherwise permitted under such clauses that are deemed to occur simultaneously, only the ultimate transferee or distributee in such series shall be required to sign and deliver such a lock-up agreement and (ii) if the undersigned is required to file a report under Section 16(a) of the Exchange Act reporting such transfer during the Restricted Period, the undersigned shall clearly indicate in the footnotes thereto the nature and conditions of such transfer, that such transfer is not for value and that the Lock-Up Securities subject to such transfer remain subject to restrictions set forth herein; (d) facilitating the establishment of a

A-2

trading plan on behalf of a shareholder, officer or director of the Company pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that (i) such plan does not provide for the transfer of Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Restricted Period; (e) transfer of Lock-Up Securities pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction or transactions made to all or substantially all holders of the Company’s Common Stock and approved by the board of directors of the Company the result of which is that any “person” or “group” (within the meaning of Section 13(d) of the Exchange Act), shall or would become, after giving effect to such transaction or transactions, the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of the total voting power of the voting securities of the Company), provided that in the event that such tender offer, merger, consolidation or other such transaction or transactions shall not be completed, the undersigned’s Lock-Up Securities shall remain subject to the provisions of this agreement during the Restricted Period; (f)(i) as a result of the operation of law, or pursuant to an order of a court (including a domestic order, divorce settlement, divorce decree or separation agreement) or regulatory agency or (ii) by will, other testamentary document or intestate succession, provided that no filing by the undersigned or any party (transferor or transferee) under the Exchange Act, or other public announcement, shall be required or shall be voluntarily made in connection with any such transfer during the Restricted Period (other than a filing on a Form 5 that shall disclose that such transfer was a result of the operation of law, or pursuant to an order of a court or regulatory agency or by will, other testamentary document or intestate succession); (g) the repurchase of Lock-Up Securities by the Company pursuant to equity award agreements or other contractual arrangements providing for the right of said repurchase in connection with the termination of the undersigned’s employment or service with the Company, provided that no filing by the undersigned under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act related thereto during the Restricted Period, such report shall disclose that such transfer was a result of the repurchase of the Lock-Up Securities or such other securities by the Company pursuant to equity award agreements or other contractual arrangements in connection with the termination of the undersigned’s employment or service with the Company; (h) pursuant to the exercise of an option to purchase Lock-Up Securities in connection with the termination or expiration of such option pursuant to its terms, provided that (1) such option was granted pursuant to a Company stock option plan or other equity incentive plan described in the registration statement on Form S-1 related to the Public Offering and the Prospectus, (2) any Lock-Up Securities received upon such exercise shall be subject to the terms of this agreement and (3) no filing by the undersigned or any party (transferor or transferee) under the Exchange Act, or other public announcement shall be voluntarily made in connection with any such transfer, and if the holder is required to file a report under the Exchange Act related thereto during the Restricted Period, such report shall disclose that such

A-3

transfer was a result of the exercise of option expiring or terminating in accordance with their terms and does not result in any aggregate reduction in the beneficial ownership; or (i) to the Company (x) pursuant to the exercise, on a “cashless” or “net exercise” basis, of any option to purchase Lock-Up Securities granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus, or (y) for the purpose of satisfying any withholding taxes (including estimated taxes) due as a result of the exercise of any option to purchase Lock-Up Securities or the vesting of any equity awards granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus, provided that no filing by the undersigned or any party (transferor or transferee) under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act related thereto during the Restricted Period, such report shall disclose that such transfer was a result of the exercise, on a “cashless” or “net exercise” basis, of any option to purchase Lock-Up Securities granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus, or for the purpose of satisfying any withholding taxes (including estimated taxes) due as a result of the exercise of any option to purchase Securities or the vesting of any equity awards granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus. In addition, the undersigned agrees that, without the prior written consent of Morgan Stanley on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing restrictions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the offering.

If the undersigned is an officer or director of the Company, (i) Morgan Stanley agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Common Stock or other Lock-Up Securities, Morgan Stanley will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by Morgan Stanley hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration or to an immediate family member as defined in FINRA Rule 5130(i)(5) and (b) the transferee has agreed in writing to be bound by the same terms described in this agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

A-4

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

The undersigned acknowledges and agrees that the Underwriters have not provided any recommendation or investment advice nor have the Underwriters solicited any action from the undersigned with respect to the Public Offering of the Shares and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriters may provide certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection with the Public Offering, the Underwriters are not making a recommendation to you to participate in the Public Offering or sell any Shares at the price determined in the Public Offering, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

The undersigned hereby consents to receipt of this agreement in electronic form and understands and agrees that this agreement may be signed electronically. In the event that any signature is delivered by facsimile transmission, electronic mail, or otherwise by electronic transmission evidencing an intent to sign this agreement, such facsimile transmission, electronic mail or other electronic transmission shall create a valid and binding obligation of the undersigned with the same force and effect as if such signature were an original. Execution and delivery of this agreement by facsimile transmission, electronic mail or other electronic transmission is legal, valid and binding for all purposes.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

This agreement shall automatically terminate and be of no further effect upon the earliest to occur, if any, of: (i) the date of filing with the SEC of a notice of withdrawal of the registration statement on Form S-1 related to the Public Offering pursuant to Rule 477 promulgated under the Securities Act of 1933, as amended, prior to its effectiveness, (ii) the date that the Company advises the Representatives in writing prior to the execution of the Underwriting Agreement that it has determined not to proceed with the Public Offering, (iii) the date that the Underwriting Agreement (other than the provisions thereof that survive termination) terminates or is terminated prior to payment for and delivery of any Shares to be sold thereunder, and (iv) July 31, 2021, in the event that the Underwriting Agreement has not been executed on or before that date.

This agreement shall be governed by and construed in accordance with the laws of the State of New York.

ARTICLE FIVE

Section 1. Board of Directors. Except as otherwise provided in this Certificate or the DGCL, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

Section 2. Number of Directors. Subject to any rights of the holders of any series of Preferred Stock then outstanding to elect additional directors under specified circumstances or otherwise, the number of directors which shall constitute the Board of Directors shall initially be nine (9) and, thereafter, shall be fixed from time to time exclusively by resolution of the Board.

Section 3. Classes of Directors. The directors of the Corporation, other than those who may be elected by the holders of any series of Preferred Stock, shall be divided into three classes, as nearly equal in number as possible, designated Class I, Class II and Class III.

Section 4. Election and Term of Office. Subject to the rights of the holders of any series of Preferred Stock then outstanding, the directors shall be elected by a plurality of the votes cast.

At each annual meeting of stockholders after the IPO Date, directors elected to replace those of a class whose terms expire at such annual meeting shall be elected to hold office until the third succeeding annual meeting after their election and until their respective successors shall have been duly elected and qualified. Each such director shall hold office until the annual meeting of stockholders for the year in which such director’s term expires and a successor is duly elected and qualified or until his or her earlier death, resignation or removal. Nothing in this Certificate shall preclude a director from serving consecutive terms. Elections of directors need not be by written ballot unless the Bylaws of the Corporation (as amended and/or restated the “Bylaws”) shall so provide.

Section 5. Newly-Created Directorships and Vacancies. Subject to the rights of the holders of any series of Preferred Stock then outstanding and except as otherwise provided in the Nomination Agreement, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the Board of Directors resulting from death, resignation, disqualification, removal from office or any other cause may be filled only by resolution of a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and may not be filled in any other manner. A director elected or appointed to fill a vacancy shall serve for the unexpired term of his or her predecessor in office and until his or her successor is elected and qualified or until his or her earlier death, resignation or removal. A director elected or appointed to fill a position resulting from an increase in the number of directors shall hold office until the next election of the class for which such director shall have been elected or appointed and until his or her successor is elected and qualified, or until his or her earlier death, resignation or removal. No decrease in the authorized number of directors shall shorten the term of any incumbent director.

Section 6. Removal and Resignation of Directors. Subject to the rights of the holders of any series of Preferred Stock then outstanding, (i) prior to the first date (the “Trigger Date”) on which Vista Equity Partners Fund VI, L.P., Vista Equity Partners Fund VI-A, L.P., and VEPF VI FAF, L.P. (collectively, “Vista”) and their Affiliated Companies (as defined herein) cease to beneficially own in the aggregate (directly or indirectly) 40% or more of the voting power of the then outstanding shares of capital stock of the Corporation then entitled to vote generally in the election of directors (“Voting Stock”), directors may be removed with or without cause upon the affirmative vote of stockholders representing at least a majority of the voting power of the then outstanding shares of Voting Stock, voting together as a single class and (ii) on and after the Trigger Date, so long as the Board is classified, directors may be removed only for cause and only upon the affirmative vote of the holders of at least sixty-six and two-thirds percent (66²⁄₃%) of the voting power of the then outstanding shares of Voting Stock. Any director may resign at any time upon notice in writing or by electronic transmission to the Corporation.

Section 7. Rights of Holders of Preferred Stock. Notwithstanding the provisions of this ARTICLE FIVE, whenever the holders of one or more series of Preferred Stock shall have the right, voting separately or together by series, to elect directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and other features of such directorship shall be subject to the rights of such series of Preferred Stock. During any period when the holders of any series of Preferred Stock, voting separately as a series or together with one or more series, have the right to elect additional directors, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions, and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, resignation, disqualification or removal. Except as otherwise provided by the Board of Directors in the resolution or resolutions establishing such series, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such stock, the terms of office of all such additional directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate (in which case each such director thereupon shall cease to be qualified as, and shall cease to be, a director) and the total authorized number of directors of the Corporation shall automatically be reduced accordingly.

ARTICLE SEVEN

Section 1. Action by Consent. Prior to the first date (the “Stockholder Consent Trigger Date”) on which Vista and its Affiliated Companies (as defined herein) cease to beneficially own in the aggregate (directly or indirectly) at least 35% of the voting power of the then outstanding Voting Stock, any action which is required or permitted to be taken by the Corporation’s stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of the Corporation’s stock entitled to vote thereon were present and voted. On and after the Stockholder Consent Trigger Date, any action required or permitted to be taken by the Corporation’s stockholders may be taken only at a duly called annual or special meeting of the Corporation’s stockholders and the power of stockholders to act by consent without a meeting is specifically denied; provided, however, that any action required or permitted to be taken by the holders of Preferred Stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without a vote, to the extent expressly so provided in the resolutions creating such series of Preferred Stock.

Section 2. Special Meetings of Stockholders. Subject to the rights of the holders of any series of Preferred Stock then outstanding and to the requirements of applicable law, special meetings of stockholders of the Corporation may be called only (i) by or at the direction of the Chair of the Board of Directors or by the Board of Directors pursuant to a written resolution adopted by the affirmative vote of the majority of the total number of directors that the Corporation would have if there were no vacancies and (ii) prior to the Stockholder Consent Trigger Date, by the Chair of the Board of Directors at the request of Vista in the manner provided for in the Bylaws. Any business transacted at any special meeting of stockholders shall be limited to the purpose or purposes stated in the notice of the meeting.

ARTICLE EIGHT

Section 1. Certain Acknowledgments. In recognition and anticipation that (i) certain of the directors, partners, principals, officers, members, managers, employees, operating partners and/or contractors of Vista or its Affiliated Companies (as defined below) may serve as directors or officers of the Corporation and (ii) Vista and its Affiliated Companies engage and may continue to engage in the same or similar activities or related lines of business as those in which the Corporation, directly or indirectly, may engage and/or other business activities that overlap with or compete with those in which the Corporation, directly or indirectly, may engage, and (iii) that the Corporation and its Affiliated Companies may engage in material business transactions with Vista and its Affiliated Companies, and that the Corporation is expected to benefit therefrom, the provisions of this ARTICLE EIGHT are set forth to regulate and define the conduct of certain affairs of the Corporation as they may involve Vista and/or its Affiliated Companies and/or their respective directors, partners, principals, officers, members, managers, employees, operating partners and/or contractors, including any of the foregoing who serve as officers or directors of the Corporation (Vista and/or its Affiliated Companies and all such other persons each an “Exempted Person” and collectively, the “Exempted Persons”), and the powers, rights, duties and liabilities of the Corporation and its officers, directors and stockholders in connection therewith. As used in this Certificate, “Affiliated Companies” shall mean (a) in respect of Vista, any entity that controls, is controlled by or under common control with Vista (other than the Corporation and any company that is controlled by the Corporation) and any investment funds managed by Vista and (b) in respect of the Corporation, any entity controlled by the Corporation.

Section 2. Competition and Corporate Opportunities. To the fullest extent permitted by applicable law, none of the Exempted Persons shall have any fiduciary duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as the Corporation or any of its Affiliated Companies, and no Exempted Person shall be liable to the Corporation or its stockholders for breach of any fiduciary or other duty (whether contractual or otherwise) solely by reason of any such activities of such Exempted Person. To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its Affiliated Companies, renounces any interest or expectancy of the Corporation and its Affiliated Companies in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to any of the Exempted Persons, even if the opportunity is one that the Corporation or its Affiliated Companies might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each Exempted Person shall have no duty to communicate or offer such business opportunity to the Corporation or its Affiliated Companies and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation, any of its Affiliated Companies or its stockholders for breach of any fiduciary or other duty (whether contractual or otherwise), as a director, officer or stockholder of the Corporation solely, by reason of the fact that Vista, its Affiliated Companies or any such Exempted Person pursues or acquires such business opportunity, sells, assigns, transfers or directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or any of its Affiliated Companies. For the avoidance of doubt, each of the Exempted Persons shall, to the fullest extent permitted by law, have the right to, and shall have no duty (whether contractual or otherwise) not to, directly or indirectly: (A) engage in the same, similar or competing business activities or lines of business as the Corporation or its Affiliated Companies, (B) do business with any client or customer of the Corporation or its Affiliated Companies, or (C) make investments in competing businesses of the Corporation or its Affiliated Companies, and such acts shall not be deemed wrongful or improper. Notwithstanding anything to the contrary in this Section 2, the Corporation does not renounce any interest or expectancy it may have in any business opportunity that is expressly offered to any director or officer of the Corporation solely in his or her capacity as such, and not in any other capacity.

Section 3. Certain Matters Deemed Not Corporate Opportunities. In addition to and notwithstanding the foregoing provisions of this ARTICLE EIGHT, a corporate opportunity shall not be deemed to belong to the Corporation if it is a business opportunity the Corporation is not financially able or contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectancy.

Section 4. Amendment of this Article. Subject to the rights of the holders of any series of Preferred Stock then outstanding, and in addition to any vote required by applicable law or this Certificate (including any certificate of designation relating to any series of Preferred Stock), the affirmative vote of the holders of at least eighty percent (80%) of the voting power of the then outstanding shares of Voting Stock, voting together as a single class, shall be required to alter, amend or repeal, or to adopt any provision inconsistent with, this ARTICLE EIGHT; provided however, that, to the fullest extent permitted by law, neither the alteration, amendment or repeal of this ARTICLE EIGHT nor the adoption of any provision of this Certificate inconsistent with this ARTICLE EIGHT shall apply to or have any effect on the liability or alleged liability of any Exempted Person for or with respect to any activities or opportunities which such Exempted Person becomes aware prior to such alteration, amendment, repeal or adoption.

Section 5. Deemed Notice. Any person or entity purchasing or otherwise acquiring or holding any interest in any shares of the Corporation shall be deemed to have notice of and to have consented to the provisions of this ARTICLE EIGHT.

Section 3. Exceptions to Prohibition on Interested Stockholder Transactions. The restrictions contained in this ARTICLE NINE shall not apply if:

(a) a stockholder becomes an Interested Stockholder inadvertently and (i) as soon as practicable divests itself of ownership of sufficient shares so that the stockholder ceases to be an Interested Stockholder; and (ii) would not, at any time within the three- year period immediately prior to a Business Combination between the Corporation and such stockholder, have been an Interested Stockholder but for the inadvertent acquisition of ownership; or

Section 4. Notice of Meetings. Whenever stockholders are required or permitted to take action at a meeting, notice of the meeting shall be given that shall state the place, if any, date, and time of the meeting of the stockholders, the means of remote communications, if any, by which stockholders and proxyholders not physically present may be deemed to be present in person and vote at such meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given, not less than 10 nor more than 60 days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting, except as otherwise provided herein or required by law (meaning, here and hereinafter, as required from time to time by the General Corporation Law of the State of Delaware (the “DGCL”)) or the Certificate of Incorporation.

(a) Form of Notice. All such notices shall be delivered in writing or in any other manner permitted by the DGCL. If mailed, such notice shall be deemed given when deposited in the United States mail, postage prepaid, addressed to the stockholder at his, her or its address as the same appears on the records of the Corporation. If delivered by courier service, notice shall be deemed given at the earlier of when the notice is received or left at such stockholder’s address as the same appears on the records of the Corporation. If given by electronic mail, notice shall be deemed given when directed to such stockholder’s electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail or such notice is prohibited by the DGCL.

Neither the business to be transacted at, nor the purpose of, any meeting of the stockholders of the Corporation need be specified in any waiver of notice of such meeting. Attendance of a stockholder of the Corporation at a meeting of such stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened and does not further participate in the meeting.

(c) Notice by Electronic Transmission. Notwithstanding Section 4(a) of this ARTICLE II, a notice may not be given by electronic transmission from and after the time: (i) the Corporation is unable to deliver by electronic transmission two (2) consecutive notices given by the Corporation; and (ii) such inability becomes known to the secretary or an assistant secretary of the Corporation or to the transfer agent or other person responsible for the giving of notice. However, the inadvertent failure to treat such inability as a revocation shall not invalidate any

meeting or other action. For purposes of these Bylaws, except as otherwise limited by applicable law, the term “electronic transmission” means any form of communication not directly involving the physical transmission of paper, including the use of, or participation in, one or more electronic networks or databases (including one or more distributed electronic networks or databases), that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such recipient through an automated process. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Corporation. A notice by electronic mail will include any files attached thereto and any information hyperlinked to a website if such electronic mail includes the contact information of an officer or agent of the corporation who is available to assist with accessing such files or information.

Section 5. List of Stockholders. The Corporation shall prepare, at least 10 days before each meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, provided, however, if the record date for determining the stockholders entitled to vote is less than 10 days before the meeting date, the list shall reflect the stockholders entitled to vote as of the 10th day before the meeting date, arranged in alphabetical order and showing the address of each such stockholder and the number of shares registered in the name of each such stockholder. Nothing contained in this section shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least 10 days prior to the meeting: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the Corporation. In the event the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, the list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Except as otherwise provided by law, the list shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 5 or to vote in person or by proxy at any meeting of stockholders.

Section 6. Quorum. The holders of a majority in voting power of the outstanding capital stock entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by law, by the Certificate of Incorporation or these Bylaws. If a quorum is not present, the chair of the meeting or the holders of a majority of the voting power present in person or represented by proxy at the meeting and entitled to vote at the meeting may adjourn the meeting to another time and/or place from time to time until a quorum shall be present in person or represented by proxy. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one class or series) voting as a separate class or series, the holders of a majority in voting power of the outstanding stock of such class or series shall constitute a quorum (as to such class or series) for the transaction of such item of business. A quorum once established at a meeting shall not be broken by the withdrawal of enough votes to leave less than a quorum.

Section 7. Adjourned Meetings. Any meeting of stockholders, annual or special, may adjourn from time to time to reconvene at the same or some other place. When a meeting is adjourned to another time and place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 30 days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for stockholders entitled to vote is fixed for the adjourned meeting, the Board of Directors shall fix a new record date for notice of such adjourned meeting, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors and, except as otherwise required by law, shall not be more than 60 days nor less than 10 days before the date of such adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such adjourned meeting as of the record date fixed for notice of such adjourned meeting.

Section 8. Vote Required. Subject to the rights of the holders of any series of preferred stock then outstanding, when a quorum has been established, all matters other than the election of directors shall be determined by the affirmative vote of the majority of voting power of capital stock present in person or represented by proxy at the meeting and entitled to vote on the subject matter, unless by express provisions of the DGCL or other an applicable law, the rules of any stock exchange upon which the Corporation’s securities are listed, any regulation applicable to the Corporation or its securities, the Certificate of Incorporation or these Bylaws a minimum or different vote is required, in which case such minimum or different vote shall be the required vote for such matter. Except as otherwise provided in the Certificate of Incorporation, directors shall be elected by a plurality of the votes cast.

Section 9. Voting Rights. Subject to the rights of the holders of any series of preferred stock then outstanding, except as otherwise provided by the DGCL or the Certificate of Incorporation, each stockholder entitled to vote at any meeting of stockholders shall be entitled to one vote in person or by proxy for each share of capital stock held by such stockholder which has voting power upon the matter in question. Voting at meetings of stockholders need not be by written ballot.

Section 10. Proxies. Each stockholder entitled to vote at a meeting of stockholders or to express consent to corporate action without a meeting may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the Corporation generally.

Notwithstanding the foregoing provisions of these Bylaws, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules, regulations and schedules promulgated thereunder with respect to the matters set forth in these Bylaws; provided, however, that any references in these Bylaws to the Exchange Act or the rules, regulations and schedules promulgated thereunder are not intended to and shall not limit the requirements applicable to any nomination or other business to be considered pursuant to Section 11 of this ARTICLE II.

(j) Effect on Other Rights. Nothing in these Bylaws shall be deemed to (A) affect any rights of the stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act, (B) confer upon any stockholder a right to have a nominee or any proposed business included in the Corporation’s proxy statement, except as set forth in the Certificate of Incorporation or these Bylaws, (C) affect any rights of the holders of any series of preferred stock to elect directors pursuant to any applicable provisions of the Certificate of Incorporation or (D) limit the exercise, the method or timing of the exercise of, the rights of any person granted by the Corporation to nominate directors (including pursuant to that Director Nomination Agreement, dated as of on or about [•], 20[•] (as amended and/or restated or supplemented from time to time, the “Nomination Agreement”), by and among the Corporation and the investors named therein, which rights may be exercised without compliance with the provisions of this Section 11 of ARTICLE II.

Section 12. Fixing a Record Date for Stockholder Meetings. In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than 60 days nor less than 10 days before the date of such meeting. If the Board of Directors so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the next day preceding the day on which notice is first given, or, if notice is waived, at the close of business on the day next preceding the day on

14

which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting in conformity herewith; and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance with the foregoing provisions of this Section 12 at the adjourned meeting.

Section 13. Action by Stockholders Without a Meeting. So long as stockholders of the Corporation have the right to act by written consent in accordance with Section 1 of ARTICLE SEVEN of the Certificate of Incorporation, the following provisions shall apply:

(a) Record Date. For the purpose of determining the stockholders entitled to consent to corporate action without a meeting as may be permitted by the Certificate of Incorporation or the certificate of designation relating to any outstanding series of preferred stock, the Board of Directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than ten (10) (or the maximum number permitted by applicable law) days after the date on which the resolution fixing the record date is adopted by the Board of Directors. Other than the Principal Stockholder, any stockholder of record seeking to have the stockholders authorize or take action by consent in lieu of a meeting shall, by written notice delivered to the Secretary at the Corporation’s principal place of business during regular business hours, request that the Board of Directors fix a record date, which notice shall include the text of any proposed resolutions. Notices delivered pursuant to Section 13(a) of this ARTICLE II will be deemed received on any given day only if received prior to the close of business on such day (and otherwise shall be deemed received on the next succeeding business day). The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such written notice is properly delivered to and deemed received by the Secretary, adopt a resolution fixing the record date (unless a record date has previously been fixed by the Board of Directors pursuant to the first sentence of this Section 13(a)). If no record date has been fixed by the Board of Directors pursuant to this Section 13(a) or otherwise within ten (10) days of receipt of a valid request by a stockholder, the record date for determining stockholders entitled to consent to corporate action without a meeting, when no prior action by the Board of Directors is required pursuant to applicable law, shall be the first date after the expiration of such ten (10) day time period on which a signed consent setting forth the action taken or proposed to be taken is delivered to the Corporation pursuant to Section 13(b); provided, however, that if prior action by the Board of Directors is required by applicable law, the record date for determining stockholders entitled to consent to corporate action without a meeting shall in such an event be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

(b) Generally. No consent shall be effective to take the corporate action referred to therein unless consents signed by a sufficient number of stockholders to take such action are delivered to the Corporation, in the manner required by this Section 13, within sixty (60) (or the maximum number permitted by applicable law) days of the first date on which a consent is delivered to the Corporation in the manner required by applicable law. The validity of any consent executed by a proxy for a stockholder pursuant to an electronic transmission transmitted to such proxy holder by or upon the authorization of the stockholder shall be determined by or at the

15

direction of the Secretary. A written record of the information upon which the person making such determination relied shall be made and kept in the records of the proceedings of the stockholders. Any such consent shall be inserted in the minute book as if it were the minutes of a meeting of stockholders. Prompt notice of the taking of the corporate action without a meeting by less than unanimous consent shall be given by the Corporation (at its expense) to those stockholders who have not consented and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that consents signed by a sufficient number of holders to take the action were delivered to the Corporation.

Section 14. Conduct of Meetings.

(a) Generally. Meetings of stockholders shall be presided over by the Chair of the Board, if any, or in the Chair’s absence or disability, by the Chief Executive Officer, or in the Chief Executive Officer’s absence or disability, by the President, or in the President’s absence or disability, by a Vice President (in the order as determined by the Board of Directors), or in the absence or disability of the foregoing persons by a chair designated by the Board of Directors, or in the absence or disability of such person, by a chair chosen at the meeting. The Secretary shall act as secretary of the meeting, but in the Secretary’s absence or disability the chair of the meeting may appoint any person to act as secretary of the meeting.

(b) Rules, Regulations and Procedures. The Board of Directors may adopt by resolution such rules, regulations and procedures for the conduct of any meeting of stockholders of the Corporation as it shall deem appropriate including, without limitation, such guidelines and procedures as it may deem appropriate regarding the participation by means of remote communication of stockholders and proxyholders not physically present at a meeting. Except to the extent inconsistent with such rules, regulations and procedures as adopted by the Board of Directors, the chair of any meeting of stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chair, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the chair of the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present; (iii) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the chair of the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; (v) limitations on the time allotted to questions or comments by participants; and (vi) restrictions on the use of mobile phones, audio or video recording devices and similar devices at the meeting. The chair of the meeting of stockholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall, if the facts warrant, determine and declare to the meeting that a nomination or matter or business was not properly brought before the meeting and if such chair should so determine, such chair shall so declare to the meeting and any such matter or business not properly brought before the meeting shall not be transacted or considered. Unless and to the extent determined by the Board of Directors or the chair of the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure. The chair of the meeting shall announce at the meeting when the polls for each matter to be voted upon at the meeting will be opened and closed. After the polls close, no ballots, proxies or votes or any revocations or changes thereto may be accepted.

16

The chair of the meeting shall have the power, right and authority, for any or no reason, to convene, recess and/or adjourn any meeting of stockholders.

(c) Inspectors of Elections. The Corporation may, and to the extent required by law shall, in advance of any meeting of stockholders, appoint one or more inspectors of election to act at the meeting and make a written report thereof. One or more other persons may be designated as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the chair of the meeting shall appoint one or more inspectors to act at the meeting. Unless otherwise required by law, inspectors may be officers, employees or agents of the Corporation. No person who is a candidate for an office at an election may serve as an inspector at such election. Each inspector, before entering upon the discharge of such inspector’s duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector’s ability. The inspector shall have the duties prescribed by law and, when the vote is completed, shall make a certificate of the result of the vote taken and of such other facts as may be required by law.

Section 15. Remote Communication. If authorized by the Board in its sole discretion, and subject to such guidelines and procedures as the Board may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication:

(a) participate in a meeting of stockholders; and

(b) be deemed present in person and vote at a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication,

provided that

(c) the Corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder;

(d) the Corporation shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings; and

(e) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the Corporation.

Section 3. Regular Meetings and Special Meetings. Regular meetings, other than the annual meeting, of the Board of Directors may be held without notice at such time and at such place as shall from time to time be determined by resolution of the Board of Directors and publicized among all directors.

Any and all business may be transacted at a special meeting of the Board of Directors.

Section 4. Notice of Meetings. Notice of regular meetings of the Board of Directors need not be given except as otherwise required by law or these Bylaws. Notice of each special meeting of the Board of Directors, and of each regular and annual meeting of the Board of Directors for which notice is required, shall be given by the Secretary as hereinafter provided in this Section 4. Such notice shall be state the date, time and place, if any, of the meeting. Notice of any special meeting, and of any regular or annual meeting for which notice is required, shall be given to each director at least (a) twenty-four (24) hours before the meeting if by telephone or by being personally delivered or sent by overnight courier, telecopy, electronic transmission, email or similar means or (b) five (5) days before the meeting if delivered by mail to the director’s residence or usual place of business. Such notice shall be deemed to be delivered when deposited in the United States mail so addressed, with postage prepaid, or when transmitted if sent by telex, telecopy, electronic transmission, email or similar means. Neither the business to be transacted at, nor the purpose of, any special meeting of the Board of Directors need be specified in the notice or waiver of notice of such meeting.

Section 5. Waiver of Notice. Any director may waive notice of any meeting of directors by a writing signed by the director or by electronic transmission. Any member of the Board of Directors or any committee thereof who is present at a meeting shall have waived notice of such meeting except when such member attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened and does not further participate in the meeting. Such member shall be conclusively presumed to have assented to any action taken unless his or her dissent shall be entered in the minutes of the meeting or unless his or her written dissent to such action shall be filed with the person acting as the secretary of the meeting before the adjournment thereof or shall be forwarded by registered mail to the secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to any member who voted in favor of such action.

Section 6. Chair of the Board, Quorum, Required Vote and Adjournment. The Board of Directors may elect a Chair of the Board.

At all meetings of the Board of Directors, a majority of the directors then in office shall constitute a quorum for the transaction of business, provided, however, that a quorum shall never be less than one-third the total number of directors. Unless by express provision of an applicable law, the Certificate of Incorporation or these Bylaws a different vote is required, the vote of a majority of directors present at a meeting at which a quorum is present shall be the act of the Board of Directors. At any meeting of the Board of Directors, business shall be transacted in such order and manner as the Board of Directors may from time to time determine. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may, to the fullest extent permitted by law, adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Section 7. Committees.

(a) The Board of Directors may designate one or more committees, including an executive committee, consisting of one or more of the directors of the Corporation, and any committees required by the rules and regulations of such exchange as any securities of the Corporation are listed. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Except to the extent restricted by applicable law or the Certificate of Incorporation, each such committee, to the extent provided by the DGCL and in the resolution creating it, shall have and may exercise all the powers and authority of the Board of Directors. Each such committee shall serve at the pleasure of the Board of Directors. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors upon request.

(b) Each committee of the Board of Directors may fix its own rules of procedure and shall hold its meetings as provided by such rules, except as may otherwise be provided by a resolution of the Board of Directors designating such committee. Unless otherwise provided in such a resolution, the presence of at least a majority of the members of the committee shall be necessary to constitute a quorum. All matters shall be determined by a majority vote of the members present at a meeting at which a quorum is present. Unless otherwise provided in such a resolution, in the event that a member and that member’s alternate, if alternates are designated by the Board of Directors, of such committee is or are absent or disqualified, the member or members present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any such absent or disqualified member.

19

Section 8. Action by Written Consent. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors, or of any committee thereof, may be taken without a meeting if all members of the Board of Directors or such committee, as the case may be, consent thereto in writing or by electronic transmission. After the action is taken, the consent or consents relating thereto shall be filed with the minutes of proceedings of the board or committee in the same paper form or electronic form as the minutes are maintained.

The Board of Directors shall have the authority to fix the compensation, including fees, reimbursement of expenses and equity compensation, of directors for services to the Corporation in any capacity, including for attendance of meetings of the Board of Directors or participation on any committees.

ARTICLE V

CERTIFICATES OF STOCK

Section 1. Form. The shares of stock of the Corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution that some or all of any or all classes or series of its stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Corporation. If shares are represented by certificates, the certificates shall be in such form as required by applicable law and as determined by the Board of Directors. Each certificate shall certify the number of shares owned by such holder in the Corporation and shall be signed by, or in the name of the Corporation by two authorized officers of the Corporation including, but not limited to, the Chair of the Board (if an officer), the Chief Executive Officer, the President, a Vice President, the Chief Financial Officer, the Treasurer, the Secretary and an Assistant Secretary of the Corporation. Any or all signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed, or whose facsimile signature or signatures have been used on, any such certificate or certificates shall cease to be such officer, transfer agent or registrar of the Corporation whether because of death, resignation or otherwise before such certificate or certificates have been issued by the Corporation, such certificate or certificates may nevertheless be issued as though the person or persons who signed such certificate or certificates or whose facsimile signature or signatures have been used thereon had not ceased to be such officer, transfer agent or registrar of the Corporation at the date of issue. All certificates for shares shall be consecutively numbered or otherwise identified. The Board of Directors may appoint a bank or trust company organized under the laws of the United States or any state thereof to act as its transfer agent or registrar, or both in connection with the transfer of any class or series of securities of the Corporation. The Corporation, or its designated transfer agent or other agent, shall keep a book or set of books to be known as the stock transfer books of the Corporation, containing the name of each holder of record, together with such holder’s address and the number and class or series of shares held by such holder and the date of issue. When shares are represented by certificates, the Corporation shall issue and deliver to each holder to whom such shares have been issued or transferred, certificates representing the shares owned by such holder, and shares of stock of the Corporation shall only be

23

transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, upon surrender to the Corporation or its designated transfer agent or other agent of the certificate or certificates for such shares endorsed by the appropriate person or persons, with such evidence of the authenticity of such endorsement, transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps. In that event, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate or certificates and record the transaction on its books. When shares are not represented by certificates, shares of stock of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, with such evidence of the authenticity of such transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps, and within a reasonable time after the issuance or transfer of such shares, the Corporation shall, if required by applicable law, send the holder to whom such shares have been issued or transferred a written statement of the information required by applicable law. Unless otherwise provided by applicable law, the Certificate of Incorporation, Bylaws or any other instrument, the rights and obligations of the holders of uncertificated stock and the rights and obligations of the holders of certificates representing stock of the same class and series shall be identical.

Section 2. Lost Certificates. The Corporation may issue or direct a new certificate or certificates or uncertificated shares to be issued in place of any certificate or certificates previously issued by the Corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the owner of the lost, stolen or destroyed certificate. When authorizing such issue of a new certificate or certificates or uncertificated shares, the Corporation may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his or her legal representative, to give the Corporation a bond in such sum as it may direct, sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

Section 3. Registered Stockholders. The Corporation shall be entitled to recognize the exclusive right of a person registered on its records as the owner of shares of stock to receive dividends, to vote, to receive notifications and otherwise to exercise all the rights and powers of an owner, except as otherwise required by applicable law.

ARTICLE VII

INDEMNIFICATION

Section 1. Right to Indemnification and Advancement. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including involvement, without limitation, as a witness) in any actual or threatened action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, manager, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director or officer or in any other capacity while serving as a director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto), against all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, excise taxes or penalties under the Employee Retirement Income Security Act of 1974, as amended from time to time (“ERISA”) and any other penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that, except as provided in this Section 2 of this ARTICLE VII with respect to proceedings to enforce rights to indemnification and advance of expenses (as defined below), the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized in the specific case by the Board of Directors of the Corporation. In addition to the right to indemnification conferred herein, an indemnitee shall also have the right, to the fullest extent not prohibited by law, to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition (an “advance of expenses”); provided, however, that if and to the extent that the DGCL requires, an advance of expenses shall be made only upon delivery to the Corporation of an undertaking (an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section 1 or otherwise. The

26

Corporation may also, by action of its Board of Directors, provide indemnification and advancement to employees and agents of the Corporation. Any reference to an officer of the Corporation in this ARTICLE VII shall be deemed to refer exclusively to the Chair of the Board of Directors, Chief Executive Officer, President, Secretary and Treasurer of the Corporation appointed pursuant to ARTICLE IV, and to any Vice President, Assistant Secretary, Assistant Treasurer or other officer of the Corporation appointed by the Board of Directors pursuant to ARTICLE IV of these By-laws, and any reference to an officer of any other enterprise shall be deemed to refer exclusively to an officer appointed by the board of directors or equivalent governing body of such other entity pursuant to the certificate of incorporation and bylaws or equivalent organizational documents of such other enterprise. The fact that any person who is or was an employee of the Corporation or an employee of any other enterprise has been given or has used the title of “Vice President” or any other title, including any titled granted to such person by the Chief Executive Officer pursuant to ARTICLE IV, Section 11, that could be construed to suggest or imply that such person is or may be an officer of the Corporation or of such other enterprise shall not result in such person being constituted as, or being deemed to be, an officer of the Corporation or of such other enterprise for purposes of this ARTICLE VII unless such person’s appointment to such office was approved by the Board of Directors pursuant to ARTICLE IV.

Section 2. Procedure for Indemnification. Any claim for indemnification or advance of expenses by an indemnitee under this Section 2 of ARTICLE VII shall be made promptly, and in any event within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the director or officer has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), upon the written request of the indemnitee. If the Corporation denies a written request for indemnification or advance of expenses, in whole or in part, or if payment in full pursuant to such request is not made within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the indemnitee has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), the right to indemnification or advances as granted by this ARTICLE VII shall be enforceable by the indemnitee in any court of competent jurisdiction. Such person’s costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation to the fullest extent permitted by applicable law. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of expenses where the undertaking required pursuant to Section 1 of this ARTICLE VII, if any, has been tendered to the Corporation) that the claimant has not met the applicable standard of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proof shall be on the Corporation to the fullest extent permitted by law. Neither the failure of the Corporation (including its Board of Directors, a committee thereof, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

27

Section 3. Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was or has agreed to become a director, officer, employee or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, partner, member, trustee, administrator, employee or agent of another corporation, partnership, joint venture, limited liability company, trust or other enterprise against any expense, liability or loss asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power to indemnify such person against such expenses, liability or loss under the DGCL.

Section 4. Service for Subsidiaries. Any person serving as a director, officer, partner, member, trustee, administrator, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, at least 50% of whose equity interests are owned by the Corporation (a “subsidiary” for purposes of this ARTICLE VII) shall be conclusively presumed to be serving in such capacity at the request of the Corporation.

Section 5. Reliance. Persons who after the date of the adoption of this provision become or remain directors or officers of the Corporation or who, while a director or officer of the Corporation, become or remain a director, manager, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to indemnity, advance of expenses and other rights contained in this ARTICLE VII in entering into or continuing such service. To the fullest extent permitted by law, the rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall apply to claims made against an indemnitee arising out of acts or omissions which occurred or occur both prior and subsequent to the adoption hereof. Any amendment, alteration or repeal of this ARTICLE VII that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal.

Section 6. Non-Exclusivity of Rights; Continuation of Rights of Indemnification. The rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall not be exclusive of any other right which any person may have or hereafter acquire under the Certificate of Incorporation or under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise. All rights to indemnification under this ARTICLE VII shall be deemed to be a contract between the Corporation and each director or officer of the Corporation who serves or served in such capacity at any time while this ARTICLE VII is in effect. Any repeal or modification of this ARTICLE VII or repeal or modification of relevant provisions of the DGCL or any other applicable laws shall not in any way diminish any rights to indemnification and advancement of expenses of such director or officer or the obligations of the Corporation arising hereunder with respect to any proceeding arising out of, or relating to, any actions, transactions or facts occurring prior to the final adoption of such repeal or modification.

Section 7. Merger or Consolidation. For purposes of this ARTICLE VII, references to the “Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this ARTICLE VII with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued.

28

Section 8. Savings Clause. To the fullest extent permitted by law, if this ARTICLE VII or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and advance expenses to each person entitled to indemnification under Section 1 of this ARTICLE VII as to all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, ERISA excise taxes and penalties and any other penalties and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification and advancement of expenses is available to such person pursuant to this ARTICLE VII to the fullest extent permitted by any applicable portion of this ARTICLE VII that shall not have been invalidated.

ARTICLE VIII

AMENDMENTS

These Bylaws may be amended, altered, changed or repealed or new Bylaws adopted only in accordance with Section 1 of ARTICLE TEN of the Certificate of Incorporation.

To the extent applicable, the Plan is intended to comply with the applicable requirements of Rule 16b-3, and the Plan will be limited, construed, and interpreted in a manner so as to comply therewith.

Section 3.4 Sole Discretion; Decisions Final. Any decision, interpretation, or other action made or taken by or at the direction of the Company, the Board, or the Committee (or any of their members) arising out of or in connection with the Plan will be within the sole and absolute discretion of all and each of them, as the case may be, and will be final, binding, and conclusive on the Company and all employees and Participants and their respective heirs, executors, administrators, successors, and assigns and all other Persons having an interest in the Plan.

Section 3.5 Designation of Consultants; Delegation of Authority.

(a) The Committee may designate employees of the Company and professional advisors to assist the Committee in the administration of the Plan and may grant authority to officers to grant Awards and execute agreements and other documents on behalf of the Committee, in each case to the extent permitted by Applicable Law. In the event of any designation of authority hereunder, subject to Applicable Law and any terms and conditions imposed by the Committee in connection with such designation, such designee or designees will have the power and authority to take such actions, exercise such powers, and make such determinations that are otherwise specifically designated to the Committee hereunder.

(b) The Committee may employ such legal counsel, consultants, and agents as it may deem desirable for the administration of the Plan and may rely upon any opinion received from any such counsel or consultant and any computation received from any such consultant or agent. Expenses incurred by the Committee or the Board in the engagement of any such counsel, consultant, or agent will be paid by the Company. The Committee, its members, and any Person designated under Section 3.5(a) will not be liable for any action or determination made in good faith with respect to the Plan. To the maximum extent permitted by Applicable Law, no officer of the Company or member or former member of the Committee or of the Board will be liable for any action or determination made in good faith with respect to the Plan or any Award.

(c) The Committee may delegate any or all of its powers and duties under the Plan to a subcommittee of directors or to any officer of the Company, including the power to perform administrative functions and grant Awards, provided that such delegation does not (i) violate Applicable Law, or (ii) result in the loss of an exemption under Rule 16b-3(d)(1) for Awards granted to Participants subject to Section 16 of the Exchange Act in respect of the Company. Upon any such delegation, all references in the Plan to the “Committee,” shall be deemed to include any subcommittee or officer of the Company to whom such powers have been delegated by the Committee. Any such delegation shall not limit the right of such subcommittee members or such an officer to receive Awards. The Committee may also appoint agents of the Company to assist in administering the Plan, provided, however, that such individuals may not be delegated the authority to grant or modify any Awards that will, or may, be settled in Shares.

Section 3.6 Indemnification. To the maximum extent permitted by Applicable Law and the Certificate of Incorporation and By Laws of the Company and to the extent not covered by insurance directly insuring such Person, each officer and employee of the Company and each Affiliate and member or former member of the Committee and the Board will be indemnified and held harmless by the Company against all costs and expenses and liabilities, and advanced amounts necessary to pay the foregoing at the earliest time and to the fullest extent permitted, arising out of any act or omission to act in connection with the administration of the Plan, except to the extent arising out of such officer’s, employee’s, member’s, or former member’s own fraud or bad faith. Such indemnification will be in addition to any right of indemnification the employees, officers, directors, or members or former officers, directors, or members may have under Applicable Law or under the Certificate of Incorporation or By Laws of the Company or an Affiliate. Notwithstanding any other term or condition of the Plan, this indemnification will not apply to the actions or determinations made by an individual with regard to Awards granted to himself or herself.

ARTICLE IV

SHARE LIMITATION

Section 4.1 Shares.

(a) Share Limits and Counting. The maximum number of Shares available for issuance under the Plan may not exceed [________] Shares (subject to any increase or decrease under this Section 4.1 or Section 4.2) (the “Share Reserve”). The Share Reserve may consist of authorized and unissued Shares and Shares held in or acquired for the treasury of the Company. The Share Reserve will automatically increase on each January 1 that occurs after the Effective Date, for 10 years, by an amount equal to [5]% of the total number of Shares outstanding on December 31 of the preceding calendar year, or a lesser number as may be determined by the Board. The maximum number of Shares with respect to which ISOs may be granted is [________] Shares. With respect to Stock Appreciation Rights settled in Shares, upon settlement, only the number of Shares delivered to a

Participant will count against the Share Reserve. If any Stock Option, Stock Appreciation Right, or Other Share-Based Award expires, terminates, or is cancelled for any reason without having been exercised in full, the number of Shares underlying such Award will be added back to the Share Reserve. If any Restricted Shares, Performance Awards, or Other Share-Based Awards denominated in Shares are forfeited for any reason, the number of Shares underlying such Award will be added back to the Share Reserve. Any Award settled in cash will not count against the Share Reserve. If Shares issuable upon exercise, vesting, or settlement of an Award, or Shares owned by a Participant (that are not subject to any pledge or other security interest), are surrendered or tendered to the Company in payment of the purchase or exercise price of an Award or any taxes required to be withheld in respect of an Award, in each case, in accordance with the terms of the Plan, such surrendered or tendered Shares will be added back to the Share Reserve. Awards may be granted in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by the Company or with which the Company combines (“Substitute Awards”). Substitute Awards will not count against the Share Reserve; provided that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding Stock Options intended to qualify as ISOs will count against the ISO limit above. Subject to applicable stock exchange requirements, available shares under a stockholder-approved plan of an entity acquired by the Company or with which the Company combines (as appropriately adjusted to reflect such acquisition or transaction) may be used for Awards and will not count against the Share Reserve.

(b) Annual Non-Employee Director Award Limitation. The maximum value of Awards granted during any calendar year to any Non-Employee Director for such individual’s service on the Board, taken together with any cash fees paid to that Non-Employee Director during the calendar year and the value of awards granted to the Non-Employee Director under any other compensation plan of the Company or any Affiliate during the calendar year for such individual’s service on the Board, may not exceed USD [750,000] in total value (calculating the value of any such Awards based on the grant date fair value for accounting purposes); provided, that for any calendar year in which a Non-Employee Director (i) first commences service on the Board, (ii) serves on a special committee of the Board, or (iii) serves as lead director or non-executive chair of the Board, additional compensation may be provided to such Non-Employee Director in excess of such limit; provided, further, that the limit set forth in this Section 4.1(b) shall be applied without regard to Awards or other compensation, if any, provided to a Non-Employee Director during any period in which such individual was an employee of the Company or any Affiliate or was otherwise providing services to the Company or to any Affiliate other than in the capacity as a Non-Employee Director.

Section 4.2 Changes.

(a) The existence of the Plan and any Awards will not affect in any way the right or power of the Board, the Committee, or the Stockholders to make or authorize (i) any adjustment, recapitalization, reorganization, or other change in the Company’s capital structure or its business, (ii) any merger or consolidation of the Company or any Affiliate, (iii) any issuance of bonds, debentures, or preferred or prior preference stock ahead of or affecting the Common Stock, (iv) the dissolution or liquidation of the Company or any Affiliate, (v) any sale or transfer of all or part of the assets or business of the Company or any Affiliate, or (vi) any other corporate act or proceeding.

(b) Subject to Section 11.1:

(i) In the event of any change in the outstanding Common Stock or in the capital structure of the Company by reason of any stock split, reverse stock split, recapitalization, reorganization, merger, consolidation, combination, division, exchange, spin off, extraordinary cash or stock dividend, or other relevant change in capitalization, Awards will be equitably adjusted or substituted to the extent necessary to preserve the economic intent of such Awards.

(ii) Fractional Shares resulting from any adjustment in Awards under this Section 4.2(b) will be aggregated until, and eliminated at, the time of exercise or payment by rounding to the nearest whole number. No cash settlements will be required with respect to fractional Shares eliminated by rounding. Notice of any adjustment will be given by the Committee to each Participant whose Award has been adjusted and such adjustment (whether or not such notice is given) will be effective and binding for all purposes of the Plan.

Section 4.3 Minimum Purchase Price. Notwithstanding any other term or condition of the Plan, if authorized but previously unissued Shares are issued under the Plan, such Shares may not be issued for a consideration that is less than as permitted under Applicable Law.

ARTICLE V

ELIGIBILITY

Section 5.1 General Eligibility. All current and prospective Eligible Individuals are eligible to be granted Awards. Eligibility for the grant of Awards and actual participation in the Plan will be determined by the Committee.

Section 5.2 ISOs. Notwithstanding Section 5.1, only Eligible Employees of the Company, its Subsidiaries, and any Parent are eligible to be granted ISOs.

Section 5.3 General Requirement. The vesting and exercise of Awards granted to a prospective Eligible Individual must be conditioned upon such individual actually becoming an Eligible Employee, Consultant, or Non-Employee Director, respectively.

ARTICLE VI

STOCK OPTIONS

Section 6.1 Stock Options. Stock Options may be granted alone or in addition to other Awards. Each Stock Option will be either (a) an ISO or (b) a Nonqualified Stock Option.

Section 6.2 Grants. The Committee will have the authority to grant to any Eligible Employee one or more ISOs, Nonqualified Stock Options, or both types of Stock Options. The Committee will have the authority to grant any Consultant or Non-Employee Director one or more Nonqualified Stock Options. To the extent that any Stock Option does not qualify as an ISO, such Stock Option or the portion thereof that does not so qualify will constitute a separate Nonqualified Stock Option.

Section 6.3 Terms and Conditions of Stock Options. Stock Options will be subject to terms and conditions, not inconsistent with the Plan, determined by the Committee, and the following:

(a) The exercise price per Share subject to a Stock Option will be determined by the Committee at the time of grant; provided that the per Share exercise price of a Stock Option may not be less than 100% (or, in the case of an ISO granted to a Ten Percent Stockholder, 110%) of the Fair Market Value of the Common Stock at the grant date.

(b) The term of each Stock Option will be fixed by the Committee; provided that no Stock Option may be exercisable more than 10 years after the date the Stock Option is granted; and provided, further, that the term of an ISO granted to a Ten Percent Stockholder may not exceed five years.

(c) Unless otherwise determined by the Committee in accordance with this Section 6.3, Stock Options will be exercisable at the time or times and subject to the terms and conditions determined by the Committee at the time of grant. If the Committee provides that any Stock Option is exercisable subject to certain terms and conditions, the Committee may waive those terms and conditions on the exercisability at any time at or after the time of grant in whole or in part.

(d) Subject to whatever installment exercise and waiting period terms and conditions that may apply under Section 6.3(e), to the extent vested, Stock Options may be exercised in whole or in part at any time during the Stock Option term by giving written notice of exercise to the Company specifying the number of Shares to be purchased. Such notice must be accompanied by payment in full of the exercise price as follows: (i) in cash or by check, bank draft, or money order payable to the Company; (ii) solely to the extent permitted by Applicable Law, if the Common Stock is listed on a national stock exchange, and the Committee authorizes, through a procedure whereby the Participant delivers irrevocable instructions to a broker reasonably acceptable to the Committee to deliver promptly to the Company an amount equal to the exercise price; (iii) to the extent the Committee authorizes, having the Company withhold Shares issuable upon exercise of the Stock Option, or by payment in full or in part in the form of Shares owned by the Participant, based on the Fair Market Value of the Shares on the payment date; or (iv) on such other terms and conditions that may be acceptable to the Committee. No Shares will be issued under the Plan until payment for those Shares has been made or provided for in accordance with the Plan.

(e) No Stock Option will be Transferable by the Participant other than by will or by the laws of descent and distribution, and all Stock Options will be exercisable, during the Participant’s lifetime, only by the Participant, except that the Committee may determine at the time of grant or thereafter that a Nonqualified Stock Option that is otherwise not Transferable under this Section 6.3(e) is Transferable to a Family Member in whole or in part on terms and conditions that are specified by the Committee. A Nonqualified Stock Option that is

Transferred to a Family Member under the preceding sentence (i) may not be subsequently Transferred other than by will or by the laws of descent and distribution and (ii) remains subject to the Plan and the applicable Award Agreement. Any Shares acquired upon the exercise of a Nonqualified Stock Option by a permissible transferee of a Nonqualified Stock Option or a permissible transferee under a Transfer after the exercise of the Nonqualified Stock Option will be subject to the Plan and the applicable Award Agreement.

(f) Treatment upon Separation from Service

(i) Unless otherwise determined by the Committee at the time of grant or, if no rights of the Participant are reduced, thereafter, if a Participant’s Separation from Service is by reason of death or Disability, all Stock Options that are held by such Participant that are vested and exercisable at the time of the Participant’s Separation from Service may be exercised by the Participant (or in the case of the Participant’s death, by the legal representative of the Participant’s estate) at any time within a period of 1 year from the date of such Separation from Service, but in no event beyond the expiration of the stated term of such Stock Options; provided, however, that, in the event of a Participant’s Separation from Service by reason of Disability, if the Participant dies within such exercise period, all unexercised Stock Options held by such Participant will thereafter be exercisable, to the extent to which they were exercisable at the time of death, for a period of 1 year from the date of such death, but in no event beyond the expiration of the stated term of such Stock Options.

(ii) Unless otherwise determined by the Committee at the time of grant or, if no rights of the Participant are reduced, thereafter, if a Participant’s Separation from Service is initiated by the Company without Cause, all Stock Options that are held by such Participant that are vested and exercisable at the time of the Participant’s Separation from Service may be exercised by the Participant at any time within a period of 90 calendar days after the date of such Separation from Service, but in no event beyond the expiration of the stated term of such Stock Options.

(iii) Unless otherwise determined by the Committee at the time of grant or, if no rights of the Participant are reduced, thereafter, if a Participant’s Separation from Service is voluntary (other than a voluntary Separation from Service described in Section 6.4(i)(y)), all Stock Options that are held by such Participant that are vested and exercisable at the time of the Participant’s Separation from Service may be exercised by the Participant at any time within a period of 90 calendar days after the date of such Separation from Service, but in no event beyond the expiration of the stated term of such Stock Options.

(iv) Unless otherwise determined by the Committee at the time of grant or, if no rights of the Participant are reduced, thereafter, Stock Options that are not vested as of the date of a Participant’s Separation from Service for any reason will terminate and expire as of the date of such Separation from Service.

(g) To the extent that the aggregate Fair Market Value (determined as of the time of grant) of the Common Stock with respect to which ISOs are exercisable for the first time by an Eligible Employee during any calendar year under the Plan or any other stock option plan of the Company, any Subsidiary, or any Parent exceeds USD 100,000, such Stock Options will be treated as Nonqualified Stock Options. In addition, if an Eligible Employee does not remain employed by the Company, any Subsidiary, or any Parent at all times from the time an ISO is granted until three months before the date of exercise thereof (or such other period as required by Applicable Law), such Stock Option will be treated as a Nonqualified Stock Option. Should any term or condition of the Plan not be necessary for the Stock Options to qualify as ISOs, or should any additional terms and conditions be required, the Committee may amend the Plan accordingly.

(h) Subject to the terms and conditions of the Plan, Stock Options will be evidenced by such form of agreement or grant as is approved by the Committee, and the Committee may (i) modify, extend, or renew outstanding Stock Options, and (ii) accept the surrender of outstanding Stock Options (to the extent not theretofore exercised) and authorize the granting of new Stock Options in substitution therefor (to the extent not theretofore exercised). Notwithstanding any other term or condition of the Plan, except in connection with a corporate transaction involving the Company in accordance with Section 4.2, the repricing of Options (and Stock Appreciation Rights) is prohibited without prior approval of the Stockholders. For this purpose, a “repricing” means any of the following (or any other action that has the same effect as any of the following): (A) any action that is treated as a “repricing” under GAAP, and (B) repurchasing for cash or cancelling an Option or a Stock Appreciation Right at a time when its exercise price is greater than the Fair Market Value of the underlying Shares in exchange for another Award. A cancellation and exchange under clause (B) would be considered a “repricing” regardless of whether it is treated as a “repricing” under GAAP and regardless of whether it is voluntary on the part of the Participant.

(i) The Committee may provide that a Stock Option include a term or condition whereby the Participant may elect at any time before the Participant’s Separation from Service to exercise the Stock Option as to any part or all of the Shares subject to the Stock Option before the full vesting of the Stock Option and such Shares will be subject to the terms and conditions of Article VIII and be treated as Restricted Shares. Unvested Shares so exercised may be subject to a repurchase option in favor of the Company or to any other restriction the Committee may determine.

Section 6.4 Automatic Exercise. The Committee may include a term or condition in an Award Agreement providing for the automatic exercise of a Nonqualified Stock Option on a cashless basis on the last day of the term of such Stock Option if the Participant has failed to exercise the Nonqualified Stock Option as of such date, with respect to which the Fair Market Value of the Shares underlying the Nonqualified Stock Option exceeds the exercise price of such Nonqualified Stock Option on the date of expiration of such Stock Option, subject to Section 13.5.

ARTICLE VII

STOCK APPRECIATION RIGHTS

Section 7.1 Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights may be issued either alone or in tandem with Stock Options. Stock Appreciation Rights will be subject to terms and conditions, not inconsistent with the Plan, determined by the Committee, and the following:

(a) The exercise price per Share subject to a Stock Appreciation Right will be determined by the Committee at the time of grant; provided that the per Share exercise price of a Stock Appreciation Right will not be less than 100% of the Fair Market Value of the Common Stock at the time of grant.

(b) The term of each Stock Appreciation Right will be fixed by the Committee, but may not be greater than 10 years after the date the right is granted.

(c) Unless otherwise determined by the Committee in accordance with this Section 7.1, Stock Appreciation Rights will be exercisable at the time or times and subject to the terms and conditions determined by the Committee at the time of grant. If the Committee provides that any such right is exercisable subject to certain terms and conditions, the Committee may waive those terms and conditions on the exercisability at any time at or after grant in whole or in part.

(d) Subject to whatever installment exercise and waiting period terms and conditions apply under Section 7.1(c), Stock Appreciation Rights may be exercised in whole or in part at any time in accordance with the applicable Award Agreement, by giving written notice of exercise to the Company specifying the number of Stock Appreciation Rights to be exercised.

(e) Upon the exercise of a Stock Appreciation Right, a Participant will be entitled to receive, for each right exercised, up to, but no more than, an amount in cash or Common Stock (as chosen by the Committee) equal in value to the excess of the Fair Market Value of one Share on the date that the right is exercised over the Fair Market Value of one Share on the date that the right was awarded to the Participant.

(f) Unless otherwise determined by the Committee at the time of grant or, if no rights of the Participant are reduced, thereafter, subject to the applicable Award Agreement and the Plan, upon a Participant’s Separation from Service for any reason, Stock Appreciation Rights will remain exercisable after a Participant’s Separation from Service on the same basis as Stock Options would be exercisable after a Participant’s Separation from Service in accordance with Section 6.4(f).

(g) No Stock Appreciation Rights will be Transferable by the Participant other than by will or by the laws of descent and distribution, and all such rights will be exercisable, during the Participant’s lifetime, only by the Participant.

Section 7.2 Automatic Exercise. The Committee may include a term or condition in an Award Agreement providing for the automatic exercise of a Stock Appreciation Right on a cashless basis on the last day of the term of the Stock Appreciation Right if the Participant has failed to exercise the Stock Appreciation Right as of such date, with respect to which the Fair Market Value of the Shares underlying the Stock Appreciation Right exceeds the exercise price of such Stock Appreciation Right on the date of expiration of such Stock Appreciation Right, subject to Section 13.5.

ARTICLE VIII

RESTRICTED SHARES

Section 8.1 Restricted Shares. The Committee will determine the Eligible Individuals to whom, and the time or times at which, grants of Restricted Shares will be made, the number of Restricted Shares to be awarded, the price (if any) to be paid by the Participant (subject to Section 8.2), the time or times within which such Awards will be subject to forfeiture, the vesting schedule and rights to acceleration thereof, and all other terms and conditions of the Awards.

Section 8.2 Awards and Certificates. Participants selected to receive Restricted Shares will not have any right with respect to the Award, unless and until the Participant has delivered a fully executed copy of the agreement evidencing the Award to the Company, to the extent required by the Committee, and has otherwise complied with the applicable terms and conditions of the Award. Further, such Award will be subject to the following:

(a) The purchase price of Restricted Shares will be fixed by the Committee. Subject to Section 4.3, the purchase price for Restricted Shares may be zero to the extent permitted by Applicable Law, and, to the extent required by Applicable Law, such purchase price may not be less than par value.

(b) Each Participant receiving Restricted Shares will be issued a stock certificate in respect of the Restricted Shares, unless the Committee elects to use another system, such as book entries by the transfer agent, as evidencing ownership of Restricted Shares. Such certificate will be registered in the name of the Participant, and will, in addition to any legends required by Applicable Law, bear an appropriate legend referring to the terms and conditions applicable to the Award, substantially in the following form:

“The anticipation, alienation, attachment, sale, transfer, assignment, pledge, encumbrance, or charge of the restricted shares of stock represented hereby are subject to the terms and conditions (including forfeiture) of the Integral Ad Science Holding Corp. (the “Company”) 2021 Omnibus Incentive Plan (the “Plan”) and an award agreement entered into between the registered owner and the Company dated __________ (the “Agreement”). Copies of such Plan and Agreement are on file at the principal office of the Company.”

(c) If stock certificates are issued in respect of Restricted Shares, the Committee may require that any stock certificates evidencing such Shares be held in custody by the Company until the restrictions thereon have lapsed, and that, as a condition of any grant of Restricted Shares, the Participant must deliver a duly signed stock power or other instruments of assignment, each endorsed in blank with a guarantee of signature if deemed necessary or appropriate by the Company, which would permit transfer to the Company of all or a portion of the Restricted Shares in the event that such Award is forfeited in whole or part.

Section 8.3 Terms and Conditions. Restricted Shares will be subject to terms and conditions, not inconsistent with the Plan, determined by the Committee, and the following:

(a) The Participant is not permitted to Transfer Restricted Shares during the period or periods set by the Committee (the “Restriction Period”) commencing on the date of such Award, as set forth in the applicable Award Agreement, and such agreement will set forth a vesting schedule and any event that would accelerate vesting of the Restricted Shares. Within these limits, based on service, attainment of Performance Goals, or such other factors or criteria as the Committee may determine, the Committee may condition the grant or provide for the lapse of such restrictions in installments in whole or in part, or may accelerate the vesting of all or any part of any Restricted Shares and waive the deferral terms and conditions for all or any part of any Restricted Shares.

(b) Except as provided in Section 8.3(a) and this Section 8.3(b) or as otherwise determined by the Committee, the Participant will have, with respect to Restricted Shares, all of the rights of a Stockholder, including the right to receive dividends, the right to vote such Restricted Shares, and, subject to and conditioned upon the full vesting of Restricted Shares, the right to tender those Shares. The Committee may determine at the time of grant that the payment of dividends will be deferred until, and conditioned upon, the expiration of the applicable Restriction Period.

(c) Unless otherwise determined by the Committee at the time of grant or, if no rights of the Participant are reduced, thereafter, subject to the applicable Award Agreement and the Plan, upon a Participant’s Separation from Service for any reason during the relevant Restriction Period, all Restricted Shares will be forfeited.

(d) If and when the Restriction Period expires without a prior forfeiture of the Restricted Shares, the certificates for such Shares will be delivered to the Participant. All legends will be removed from said certificates at the time of delivery to the Participant, except as otherwise required by Applicable Law or other terms and conditions imposed by the Committee.

ARTICLE IX

PERFORMANCE AWARDS

Section 9.1 Performance Awards. The Committee may grant a Performance Award to a Participant payable upon the attainment of specific Performance Goals. If the Performance Award is payable in Restricted Shares, such Shares will be transferable to the Participant only upon attainment of the relevant Performance Goal in accordance with Article VIII. If the Performance Award is payable in cash, it may be paid upon the attainment of the relevant Performance Goals either in cash or in Restricted Shares (based on the then current Fair Market Value of such Shares). Each Performance Award will be evidenced by an Award Agreement in such form that is not inconsistent with the Plan and that the Committee may approve. The Committee will condition the right to payment of any Performance Award upon the attainment of Performance Goals established under Section 9.2(c).

Section 9.2 Terms and Conditions. Performance Awards will be subject to terms and conditions, not inconsistent with the Plan, determined by the Committee, and the following:

(a) At the expiration of the applicable Performance Period, the Committee will determine the extent to which the Performance Goals established under Section 9.2(c) are achieved and the percentage of each Performance Award that has been earned.

(b) Subject to the applicable Award Agreement and the Plan, Performance Awards may not be Transferred.

(c) The Committee will establish the Performance Goals for the earning of Performance Awards based on a Performance Period applicable to each Participant or class of Participants. Such Performance Goals may incorporate terms and conditions for disregarding (or adjusting for) changes in accounting methods, corporate transactions, and other similar type events or circumstances.

(d) Unless otherwise determined by the Committee at the time of grant, amounts equal to dividends declared during the Performance Period with respect to the number of Shares covered by a Performance Award will not be paid to the Participant.

(e) After the Committee’s determination in accordance with Section 9.2(a), the Company will settle Performance Awards, in such form as determined by the Committee, in an amount equal to such Participant’s earned Performance Awards. Notwithstanding the foregoing sentence, the Committee may award an amount less than the earned Performance Awards and subject the payment of all or part of any Performance Award to additional vesting, forfeiture, and deferral terms and conditions.

(f) Subject to the applicable Award Agreement and the Plan, upon a Participant’s Separation from Service for any reason during the Performance Period for a Performance Award, the Performance Award will vest or be forfeited in accordance with the terms and conditions established by the Committee at grant.

(g) Based on service, performance, and any other factors or criteria the Committee may determine, the Committee may, at or after grant, accelerate the vesting of all or any part of any Performance Award.

ARTICLE X

OTHER SHARE-BASED AND CASH-BASED AWARDS

Section 10.1 Other Share-Based Awards. The Committee is authorized to grant to Eligible Individuals Other Share-Based Awards that are payable in, valued in whole or in part by reference to, or otherwise based on or related to Shares, including Shares awarded purely as a bonus and not subject to terms or conditions, Shares in payment of the amounts due under an incentive or performance plan sponsored or maintained by the Company or an Affiliate, stock

equivalent units, restricted stock units (“RSUs”), and Awards valued by reference to book value of Shares. Other Share-Based Awards may be granted either alone or in addition to or in tandem with other Awards. Subject to the terms and conditions of the Plan, the Committee has the authority to determine the Eligible Individuals to whom, and the time or times at which, Other Share-Based Awards will be granted, the number of Shares to be granted under such Awards, and all other terms and conditions of the Awards.

Section 10.2 Terms and Conditions. Other Share-Based Awards will be subject to terms and conditions, not inconsistent with the Plan, determined by the Committee, and the following:

(a) Subject to the applicable Award Agreement and the Plan, Shares subject to Other Share-Based Awards may not be Transferred before the date on which the Shares are issued, or, if later, the date on which any applicable restriction, performance, or deferral period lapses.

(b) Unless otherwise determined by the Committee at the time of grant, subject to the applicable Award Agreement and the Plan, the recipient of an Other Share-Based Award will not be entitled to receive, currently or on a deferred basis, dividends or dividend equivalents in respect of the number of Shares covered by the Award.

(c) All Other Share-Based Awards and any Shares covered by those awards will vest or be forfeited to the extent so provided in the Award Agreement.

(d) Common Stock issued on a bonus basis under this Article IX may be issued for no cash consideration. Common Stock purchased under a purchase right awarded under this Article X will be priced as determined by the Committee.

Section 10.3 Other Cash-Based Awards. The Committee may grant Other Cash-Based Awards to Eligible Individuals in amounts, on terms and conditions, and for consideration, including no consideration or such minimum consideration as may be required by Applicable Law. Other Cash-Based Awards may be granted subject to the satisfaction of vesting terms and conditions or may be awarded purely as a bonus and not subject to terms and conditions, and if subject to vesting, the Committee may accelerate such vesting at any time.

ARTICLE XI

CHANGE IN CONTROL

Section 11.1 Treatment of Awards upon a Change in Control. In the event of a Change in Control, and except as otherwise determined by the Committee in an Award Agreement, a Participant’s unvested Awards will not vest automatically and will be treated in accordance with one or more of the following methods as determined by the Committee:

(a) Awards, whether or not then vested, will be continued, assumed, or have new rights substituted therefor, on an economic equivalent basis, as determined by the Committee, and restrictions to which Restricted Shares or any other Award granted before the Change in Control are subject will not lapse upon the Change in Control and the Restricted Shares or other Awards will receive the same distribution as other Common Stock on terms and conditions determined by the Committee; provided that the Committee may decide to award additional Restricted Shares or other Awards in lieu of any cash distribution.

(b) The Committee may provide for the purchase of any Awards by the Company or an Affiliate for an amount of cash equal to the excess (if any) of the Fair Market Value of the Shares covered by such Awards as of the Change in Control, over the aggregate purchase or exercise price of such Awards. [For the purposes of this Section 11.1(b), to the extent applicable, Fair Market Value will be determined based on the highest price per Share paid in connection with any Change in Control.]

(c) The Committee may terminate all outstanding and unexercised Stock Options, Stock Appreciation Rights, and Other Share-Based Awards that provide for a Participant-elected exercise, effective as of the Change in Control, by delivering notice of termination to each Participant at least 20 days before the date of consummation of the Change in Control, in which case during the period from the date on which such notice of termination is delivered to the consummation of the Change in Control, each affected Participant will have the right to exercise in full all of the Participant’s Awards that are then outstanding (without regard to any terms and conditions on exercisability otherwise contained in the Award Agreements), but any such exercise will be contingent on the occurrence of the Change in Control; provided that, if the Change in Control does not take place within a specified period after giving such notice for any reason whatsoever, the notice and exercise pursuant thereto will be null and void.

(d) The Committee may make any other determination as to the treatment of Awards in connection with a Change in Control. The treatment of Awards need not be the same for all Participants. Any escrow, holdback, earnout, or similar terms and conditions in the definitive agreements relating to the Change in Control may apply to any payment to the holders of Awards to the same extent and in the same manner as such terms and conditions apply to the holders of Shares.

Section 11.2 Change in Control. Unless otherwise determined by the Committee in the applicable Award Agreement or other written agreement with a Participant approved by the Committee, a “Change in Control” means:

(a) any “person,” as that term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the Company, any trustee or other fiduciary holding securities under any employee benefit plan of the Company, or any company owned, directly or indirectly, by the Stockholders in substantially the same proportions as their ownership of Common Stock), becomes the beneficial owner (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities, other than pursuant to a Business Combination that does not constitute a Change in Control under such Section 11.2(c);

(b) during any period of 24 consecutive calendar months, individuals who were directors serving on the Board on the first day of such period (the “Incumbent Directors”) cease for any reason to constitute a majority of the Board; provided, however, that any individual becoming a director after the first day of such period whose election, or nomination for election, by the Stockholders was approved by a vote of at least a majority of the Incumbent Directors will be considered as though such individual were an Incumbent Director, but excluding, for purposes of this proviso, any such individual whose initial assumption of office occurs as a result of an actual or threatened proxy contest with respect to election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a “person” (as used in Section 13(d) of the Exchange Act), in each case, other than the Board;

(c) consummation of a reorganization, merger, consolidation, or other business combination (any of the foregoing, a “Business Combination”) of the Company or any direct or indirect subsidiary of the Company with any other corporation, in any case with respect to which the Company voting securities outstanding immediately before such Business Combination do not, immediately after such Business Combination, continue to represent (either by remaining outstanding or being converted into voting securities of the Company or any ultimate parent thereof) more than 50% of the then outstanding voting securities entitled to vote generally in the election of directors of the Company (or its successor) or any ultimate parent thereof after the Business Combination; or

(d) a complete liquidation or dissolution of the Company or the consummation of a sale or disposition by the Company of all or substantially all of the Company’s assets other than the sale or disposition of all or substantially all of the assets of the Company to a Person or Persons who beneficially own, directly or indirectly, more than 50% of the combined voting power of the outstanding voting securities of the Company at the time of the sale.

For purposes of this Section 11.2, acquisitions or sales of securities of the Company by Vista, any of its respective affiliates, or any investment vehicle or fund controlled by or managed by, or otherwise affiliated with Vista shall not constitute a Change in Control. Notwithstanding the foregoing terms and conditions of this definition, if a Change in Control constitutes a payment event with respect to any Award (or any portion of an Award) that provides for the deferral of compensation that is subject to Section 409A of the Code, a Change in Control will not be deemed to have occurred for purposes of such Award (or portion thereof) unless such transaction or series of related transactions also constitutes a “change in control event” with respect to the Company for purposes of Section 409A of the Code.

Section 11.3 Initial Public Offering not a Change in Control. Notwithstanding the foregoing terms and conditions of the definition of Change in Control, the occurrence of the Registration Date will not be considered a Change in Control.

ARTICLE XII

AMENDMENT AND TERMINATION

Section 12.1 Amendment and Termination of Plan. Subject to Section 12.3, the Board may amend or terminate the Plan at any time; provided, however, that no amendment will be effective unless approved by the Stockholders to the extent Stockholder approval is necessary to satisfy any Applicable Laws.

Section 12.2 Amendment of Awards. Subject to Section 12.3, the Committee may amend any Award at any time; provided, however, that no amendment will be effective unless approved by the Stockholders to the extent Stockholder approval is necessary to satisfy any Applicable Laws.

ARTICLE XIII

GENERAL TERMS AND CONDITIONS

Section 13.1 Legend. The Committee may require each person receiving Shares under the Plan to represent to and agree with the Company in writing that the Participant is acquiring the Shares without a view to distribution thereof. In addition to any legend required by the Plan, the certificates for Shares issued under the Plan may include any legend that the Committee deems appropriate to reflect any restrictions on Transfer. All certificates for Shares delivered under the Plan will be subject to such stop-transfer orders and other restrictions as the Committee may deem advisable under Applicable Law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

Section 13.2 Book Entry. Notwithstanding any other term or condition of the Plan, the Company may elect to satisfy any requirement under the Plan for the delivery of Share certificates through the use of another system, such as book entry or electronically.

Section 13.3 Other Plans. Nothing contained in the Plan prevents the Board from adopting other or additional compensation arrangements, subject to Stockholder approval if such approval is required, and such arrangements may be either generally applicable or applicable only in specific cases.

Section 13.4 No Right to Employment, Consultancy, or Directorship. Neither the Plan nor the grant of any Award gives any Person any right with respect to continuance of employment, consultancy, or directorship by the Company or any Affiliate, nor does the Plan or the grant of any Award cause any limitation in any way on the right of the Company or any Affiliate by which an employee is employed or a Consultant or Non-Employee Director is retained to terminate such employment, consultancy, or directorship at any time.

Section 13.5 Withholding for Taxes. The Company or an Affiliate, as the case may be, has the right to deduct from payments of any kind otherwise due to a Participant any U.S. federal, state, local or foreign taxes of any kind required by Applicable Law to be withheld (a) with respect to the grant, vesting of or other lapse of restrictions applicable to an Award, (b) upon the issuance of any Shares upon the exercise of an Option or Stock Appreciation Right, or (c) otherwise due in connection with an Award. At the time the tax obligation becomes due, the Participant must pay to the Company or the Affiliate, as the case may be, any amount that the Company or Affiliate determines to be necessary to satisfy the tax obligation. The Company or the Affiliate, as the case may be, may require or permit the Participant to satisfy the tax obligation, in whole or in part, (i) by causing the Company or Affiliate to withhold up to the maximum required number of Shares

otherwise issuable to the Participant as may be necessary to satisfy such tax obligation; (ii) by delivering to the Company or Affiliate Shares already owned by the Participant; (iii) the Company or the Affiliate withholding cash from any compensation otherwise payable to or for the benefit of the Participant, (iv) withholding from proceeds from the sale of shares of Common Stock issued to the Participant under such Award, either through a voluntary sale or a mandatory sale arranged by the Company; or (v) any other method determined by the Committee that is permissible under Applicable Law. To the extent withholding occurs as indicated in (i) or (ii) above, the Shares delivered or withheld must have an aggregate Fair Market Value approximately equal to the tax obligation. The Fair Market Value of the Shares used to satisfy the tax obligation will be determined by the Company or the Affiliate as of the date that the amount of tax to be withheld is to be determined. To the extent applicable, a Participant may satisfy his or her tax obligation only with Shares that are not subject to any repurchase, forfeiture, unfulfilled vesting, or other similar requirements.

Section 13.6 No Assignment of Benefits. No Award or other benefit payable under the Plan may, except as otherwise specifically provided by Applicable Law or permitted by the Committee, be Transferable in any manner, and any attempt to Transfer any such benefit will be void, and any such benefit will not in any manner be liable for or subject to the debts, contracts, liabilities, engagements, or torts of any Person who will be entitled to such benefit, nor will it be subject to attachment or legal process for or against such Person.

Section 13.7 Listing and Other Terms and Conditions.

(a) Unless otherwise determined by the Committee, as long as the Common Stock is listed on a national stock exchange or system sponsored by a national securities association, the issuance of Shares under an Award will be conditioned upon such Shares being listed on such exchange or system. The Company will have no obligation to issue such Shares unless and until such Shares are so listed, and the right to exercise any Stock Option or other Award with respect to such Shares will be suspended until such listing has been effected.

(b) If at any time counsel to the Company is of the opinion that any sale or delivery of Shares under an Award is or may be unlawful or result in the imposition of excise taxes on the Company, the Company will have no obligation to make such sale or delivery, or to make any application or to effect or to maintain any qualification or registration under the Securities Act or otherwise, with respect to Shares or Awards, and the right to exercise any Stock Option or other Award will be suspended until, in the opinion of said counsel, such sale or delivery would be lawful or would not result in the imposition of excise taxes on the Company.

(c) Upon termination of any period of suspension under this Section 13.7, any Award affected by such suspension that has not expired or terminated will be reinstated as to all Shares available before such suspension and as to Shares that would otherwise have become available during the period of such suspension, but no such suspension will extend the term of any Award.

(d) A Participant will be required to supply the Company with certificates, representations, and information that the Company requests and otherwise cooperate with the Company in obtaining any listing, registration, qualification, exemption, consent, and approval the Company reasonably determines necessary or appropriate.

Section 13.8 Stockholders Agreement and Other Requirements. Notwithstanding any other term or condition of the Plan, as a condition to the receipt of Shares under an Award, to the extent required by the Committee, the Participant must execute and deliver a Stockholder’s agreement and such other documentation that sets forth certain restrictions on transferability of the Shares acquired upon exercise or purchase, and such other terms and conditions as the Committee may establish. The Company may require, as a condition of exercise, the Participant to become a party to an existing Stockholders agreement (or other agreement). Any payment of cash or issuance or transfer of Shares or other property to the Participant or the Participant’s legal representative under the Plan will, to the extent thereof, be in full satisfaction of all claims of such Persons under the plan, and the Company may require the Participant or the Participant’s legal representative, as a condition to such payment or issuance or transfer, to execute a general release of all claims in favor of the Company and each Affiliate in such form as the Company may determine.

Section 13.9 Governing Law. The Plan and actions taken in connection with the Plan will be governed and construed in accordance with the laws of the U.S. State of Delaware without regard to the principles of conflicts of laws (whether of the U.S. State of Delaware or any other jurisdiction).

Section 13.10 Jurisdiction; Waiver of Jury Trial. Any suit, action, or proceeding with respect to the Plan or any Award or Award Agreement, or any judgment entered by any court of competent jurisdiction in respect of the Plan or any Award or Award Agreement, will be resolved only in the courts of the U.S. State of Delaware or the United States District Court for the District of Delaware and the appellate courts having jurisdiction of appeals in such courts. In that context, and without limiting the generality of the foregoing, each of the Company and each Participant irrevocably and unconditionally (a) submits in any proceeding relating to the Plan or any Award or Award Agreement, or for the recognition and enforcement of any judgment in respect of the Plan or any Award or Award Agreement (a “Proceeding”), to the exclusive jurisdiction of the courts of the U.S. State of Delaware or the United States District Court for the District of Delaware and the appellate courts having jurisdiction of appeals in such courts, and agrees that all claims in respect of any Proceeding will be heard and determined in such state court or, to the extent permitted by Applicable Law, in such federal court, (b) consents that any Proceeding may and will be brought in such courts and waives any objection that the Company or the Participant may have at any time after the Effective Date to the venue or jurisdiction of any Proceeding in any such court or that the Proceeding was brought in an inconvenient court and agrees not to plead or claim the same, (c) waives all right to trial by jury in any Proceeding (whether based on contract, tort, or otherwise) arising out of or relating to the Plan or any Award or Award Agreement, (d) agrees that service of process in any Proceeding may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party, in the case of a Participant, at the Participant’s address shown in the books and records of the Company or, in the case of the Company, at the Company’s principal offices, attention General Counsel, and (e) agrees that nothing in the Plan will affect the right to effect service of process in any other manner permitted by the laws of the State of Delaware.

Section 13.11 Other Benefits. No Award will be considered compensation for purposes of computing benefits under any retirement plan of the Company or any Affiliate or affect any benefit under any other benefit plan now or subsequently in effect under which the availability or amount of benefits is related to the level of compensation.

Section 13.12 Costs. The Company will bear all expenses associated with administering the Plan, including expenses of issuing Common Stock under Awards.

Section 13.13 No Right to Same Benefits. The terms and conditions of Awards need not be the same with respect to each Participant, and Awards to individual Participants need not be the same in subsequent years (if granted at all).

Section 13.14 Death; Disability. The Committee may require the transferee of a Participant to supply it with written notice of the Participant’s death or Disability and to supply it with a copy of the will (in the case of the Participant’s death) or such other evidence as the Committee deems necessary to establish the validity of the transfer of an Award. The Committee may also require the agreement of the transferee to be bound by the Plan.

Section 13.15 Section 16(b) of the Exchange Act. All elections and transactions under the Plan by Persons subject to Section 16 of the Exchange Act involving Shares are intended to comply with any applicable exemptive condition under Rule 16b-3. The Committee may establish and adopt written administrative guidelines, designed to facilitate compliance with Section 16(b) of the Exchange Act, as it may deem necessary or proper for the administration and operation of the Plan and the transaction of business thereunder.

Section 13.16 Section 409A. The Plan is intended to comply with Section 409A and will be limited, construed, and interpreted in accordance with such intent. To the extent that any Award is subject to Section 409A, it will be paid in a manner that complies with Section 409A. Notwithstanding any other provision of the Plan, any Plan provision that is inconsistent with Section 409A will be deemed to be amended to comply with Section 409A and to the extent such provision cannot be amended to comply, such provision will be null and void. The Company will have no liability to a Participant, or any other party, if an Award that is intended to be exempt from or compliant with Section 409A is not so exempt or compliant, or for any action taken by the Committee or the Company and, in the event that any amount or benefit under the Plan becomes subject to penalties under Section 409A, responsibility for payment of such penalties will rest solely with the affected Participants and not with the Company. Notwithstanding any other provision in the Plan or any Award Agreement, any payment(s) of “nonqualified deferred compensation” (within the meaning of Section 409A) that are otherwise required to be made under the Plan to a “specified employee” (as defined under Section 409A) as a result of such employee’s separation from service (other than a payment that is not subject to Section 409A) will be delayed for the first six months after such separation from service and will instead be paid (in a manner set forth in the Award Agreement) upon expiration of such delay period (or, if earlier, the date of death of the specified employee). All installment payments under the Plan will be deemed separate payments for purposes of Section 409A.

Section 13.17 California Participants. The Plan is intended to comply with Section 25102(o) of the California Corporations Code, to the extent applicable. In that regard, to the extent required by Section 25102(o), (a) the terms and conditions of any Options and Stock Appreciation Rights, to the extent vested and exercisable upon a Participant’s Separation from Service, will include any minimum exercise periods after Separation from Service required by Section 25102(o) and (b) any repurchase right of the Company or any Affiliate will include a minimum 90-day notice requirement. Any Plan term that is inconsistent with Section 25102(o) will, without further act or amendment by the Company or the Board, be reformed to comply with the requirements of Section 25102(o).

Section 13.18 Successor and Assigns. The Plan will be binding on all successors and permitted assigns of a Participant, including the estate of such Participant and the executor, administrator, or trustee of such estate.

Section 13.19 Severability of Terms and Conditions. If any term or condition of the Plan is held invalid or unenforceable, such invalidity or unenforceability will not affect any other term or condition of the Plan, and the Plan will be construed and enforced as if such term or condition had not been included.

Section 13.20 Payments to Minors, Etc. Any benefit payable to or for the benefit of a minor, an incompetent Person, or other Person incapable of receipt thereof will be considered paid when paid to such Person’s guardian or to the party providing or reasonably appearing to provide for the care of such Person, and such payment will fully discharge the obligations of the Committee, the Board, the Company, all Affiliates, and their employees, agents, and representatives with respect thereto.

Section 13.21 Lock-Up Agreement. As a condition to the grant of an Award, if requested by the Company and the lead underwriter of any public offering of Common Stock (the “Lead Underwriter”), a Participant must irrevocably agree not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of, any interest in any Common Stock or any securities convertible into, derivative of, or exchangeable or exercisable for, or any other rights to purchase or acquire Common Stock (except Common Stock included in such public offering or acquired on the public market after such offering) during such period of time after the effective date of a registration statement of the Company filed under the Securities Act that the Lead Underwriter may specify (the “Lock-Up Period”). Each Participant must sign such documents as may be requested by the Lead Underwriter to effect the foregoing. The Company may impose stop-transfer instructions with respect to Common Stock acquired under an Award until the end of such Lock-Up Period.

Section 13.22 Separation from Service for Cause; Clawbacks; Detrimental Conduct.

(a) The Company may cancel any unvested Awards if the Participant incurs a Separation from Service for Cause.

(b) All awards, amounts, or benefits received or outstanding under the Plan will be subject to clawback, cancellation, recoupment, rescission, payback, reduction, or other similar action in accordance with any Company clawback or similar policy or any Applicable Law related to such actions. A Participant’s acceptance of an Award will constitute the Participant’s acknowledgement of and consent 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 Effective Date, and any Applicable Law relating to clawback, cancellation, recoupment, rescission, payback, or reduction of compensation, and the Participant’s agreement that the Company may take any actions that may be necessary to effectuate any such policy or Applicable Law, without further consideration or action.

(c) Except as otherwise determined by the Committee, notwithstanding any other term or condition of the Plan, if a Participant engages in Detrimental Conduct, whether during the Participant’s service or after the Participant’s Separation from Service, in addition to any other penalties or restrictions that may apply under the Plan, Applicable Law, or otherwise, the Participant must forfeit or pay to the Company the following:

(i) any and all outstanding Awards granted to the Participant, including Awards that have become vested or exercisable;

(ii) any cash or Shares received by the Participant in connection with the Plan within the 36-month period immediately before the date the Participant engaged in Detrimental Conduct; and

(iii) the profit realized by the Participant from the sale, or other disposition for consideration, of any Shares received by the Participant under the Plan within the 36-month period immediately before the date the Participant engaged in Detrimental Conduct.

Section 13.23 Data Protection. A Participant’s acceptance of an Award will be deemed to constitute the Participant’s acknowledgement of and, where required, consent to the collection and processing of personal data relating to the Participant so that the Company and the Affiliates can fulfill their obligations and exercise their rights under the Plan and generally administer and manage the Plan. This data will include data about participation in the Plan and Shares offered or received, purchased, or sold under the Plan and other appropriate financial and other data (such as the date on which the Awards were granted) about the Participant and the Participant’s participation in the Plan.

Section 13.24 Unfunded Plan. The Plan is intended to constitute an “unfunded” plan for incentive and deferred compensation. With respect to any payment as to which a Participant has a fixed and vested interest but that is not yet made to a Participant by the Company, nothing in the Plan gives any Participant any right that is greater than the rights of a general unsecured creditor of the Company. The grant of an Award will not require a segregation of any of the Company’s assets for satisfaction of the Company’s payment obligation under any Award.

Section 13.25 Plan Construction. In the Plan, unless otherwise stated, the following uses apply:

(a) references to an Applicable Law refer to such Applicable Law and any amendments and supplements thereto and any successor Applicable Law, and to all valid and binding rules and regulations promulgated thereunder, court decisions, and other regulatory and judicial authority issued or rendered thereunder, as amended or supplemented, or their successors, as in effect at the relevant time;

(b) in computing periods from a specified date to a later specified date, the words “from” and “commencing on” (and the like) mean “from and including,” and the words “to,” “until,” and “ending on” (and the like) mean “to and including”;

(c) indications of time of day will be based upon the time applicable to the location of the principal headquarters of the Company;

(d) the words “include,” “includes,” and “including” (and the like) mean “include, without limitation,” “includes, without limitation,” and “including, without limitation” (and the like), respectively;

(e) all references to articles, sections, and exhibits are to articles, sections, and exhibits in or to the Plan;

(f) all words used will be construed to be of such gender or number as the circumstances and context require;

(g) the captions and headings of articles, sections, and exhibits have been inserted solely for convenience of reference and will not be considered a part of the Plan, nor will any of them affect the meaning or interpretation of the Plan;

(h) any reference to an agreement, plan, policy, form, document, or set of documents, and the rights and obligations of the parties under any such agreement, plan, policy, form, document, or set of documents, will mean the agreement, plan, policy, form, document, or set of documents as amended from time to time, and any and all modifications, extensions, renewals, substitutions, or replacements thereof; and

(i) all accounting terms not specifically defined will be construed in accordance with GAAP.

THIS OPTION AWARD AGREEMENT (this “Agreement”) is entered into by and between the Company and the 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) One third (¹⁄₃) of the Options (the “Service Options”) shall vest and become exercisable with respect to twenty-five percent (25%) of the Service Options on each of the first four (4) anniversaries of the Grant Date, subject to the Participant not incurring a Separation from Service prior to the applicable vesting date.

(b) The remaining two thirds (²⁄₃) 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 (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 (the “Vesting Condition”). 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.

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.

(a) Grant. The Company hereby grants to the Participant the number of RSUs set forth in the Grant Notice on the terms and conditions set forth in the Grant Notice, this Agreement, and the Plan.

(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. The RSUs shall vest with respect to twenty five percent (25%) of the Award on each of the first four (4) anniversaries of the date of grant, subject to the Participant not incurring a Separation from Service prior to the applicable vesting date.

3. Settlement. The Company shall issue one Share to the Participant for each RSU that becomes vested hereunder within 30 days following the date on which such RSU becomes vested. Notwithstanding the foregoing, if the Participant is employed and/or resides outside of the United States, the Company, in its sole discretion, may provide for the settlement of the RSUs in the form of (a) a cash payment (in an amount equal to the Fair Market Value of the Shares that correspond to the vested RSUs) to the extent that settlement in Shares (i) is prohibited under local law, (ii) would require the Participant, or the Company or any of its Affiliates to obtain the approval of any governmental or regulatory body in the Participant’s country of employment and/or residency, (iii) would result in adverse tax consequences for the Participant or the Company or any of its Affiliates or (iv) is administratively burdensome; or (b) Shares, but require the Participant to sell such Shares 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).

A-1

4. Forfeiture. If, prior to the settlement of the RSUs as set forth in Section 3, (a) the Participant incurs a Separation from Service for any reason, (b) the Participant materially breaches this Agreement, or (c) the Participant fails to meet the tax withholding obligations described in Section 6, the Participant shall immediately and automatically forfeit all of the Participant’s rights in respect of the RSUs.

5. Change in Control. Except to the extent Substitute Awards are granted in assumption of, or in substitution for, any then unvested RSUs granted hereunder, in the event of a Change in Control, if a Participant incurs a Separation from Service within [two (2) years] following such Change in Control, 100% of any then unvested RSUs granted hereunder shall immediately become fully vested and non-forfeitable, provided that the Participant remains in continuous Service from the Grant Date through the occurrence of the Change in Control.

6. Rights as Stockholder; Dividend Equivalents. Until such time as the RSUs have been settled pursuant to Section 3, the Participant shall have no rights as a stockholder, including, without limitation, any right to dividends or other distributions or any right to vote. Notwithstanding the foregoing, if the Company declares any cash dividend the record date of which occurs while the RSUs are outstanding, the Participant shall be credited a dividend equivalent in an amount equal to the dividend that would have been paid on the Shares underlying the RSUs had such shares been outstanding on such record date. Any such dividend equivalents shall be subject to the same vesting conditions applicable to the underlying RSU with respect to which they accrue, and shall, if the underlying RSU vests, be paid on the date on which such RSU is settled in accordance with Section 3. For purposes of clarity, if the RSUs (or any portion thereof) are forfeited by the Participant pursuant to the terms of this Agreement, then the Participant shall also forfeit the dividend equivalents, if any, accrued with respect to such forfeited RSUs. No interest will accrue on the dividend equivalents between the declaration and payment of the applicable dividends and the settlement of the dividend equivalents.

7. 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 RSUs or the underlying Shares, including, but not limited to, the grant, vesting or settlement of the RSUs, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividend equivalents and/or dividends and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs 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.

A-2

(b) To the extent that Tax-Related Items are payable, the Participant shall make arrangements satisfactory to the Company regarding the payment of any Tax-Related Items in respect of this Award 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 (which is not subject to any pledge or other security interest), net settlement, a broker-assisted sale, or 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 settlement 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 liabilities determined based on the greatest withholding rates for Tax-Related Items that may be utilized without creating adverse accounting treatment for the Company with respect to this Award, as determined by the Committee. If the obligation for Tax-Related Items is satisfied through net settlement, for tax purposes, the Participant is deemed to have been issued the full number of Shares subject to the RSUs, 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) The Participant acknowledges that there may be adverse tax consequences upon the receipt, vesting or settlement of this Award or disposition of the underlying shares and that the 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.

8. Non-Transferability. The RSUs 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. Any such purported assignment, alienation, pledge, attachment, sale, transfer, or encumbrance shall be void and unenforceable against the Company.

A-3

9. 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 RSUs 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 RSUs 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 RSUs is not subject to the supervision of the local securities authorities.

A-4

(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., RSUs) 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.

A-5

(i) Nature of Grant. In accepting the RSUs, 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 RSUs is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of RSUs, or benefits in lieu of RSUs, even if RSUs 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 RSUs 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 RSUs and any Shares acquired upon settlement of the RSUs, 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 RSUs 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 RSUs is unknown, indeterminable, and cannot be predicted with certainty;

(ix) no claim or entitlement to compensation or damages shall arise from forfeiture of the RSUs 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 RSUs, the Participant agrees not to institute any claim against the Company or the Employer;

(x) for purposes of the RSUs, 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 RSUs 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

A-6

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 RSUs 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 RSUs 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 RSUs or any amounts due to the Participant pursuant to the settlement of the RSUs or the subsequent sale of any Shares acquired upon settlement of the RSUs.

(j) Unfunded Plan. The award of RSUs is unfunded and the Participant shall be considered an unsecured creditor of the Company with respect to the Company’s obligations, if any, to issue Shares pursuant to this Agreement. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between the Participant and the Company or any other person.

(k) Appendix. Notwithstanding any provisions in this Agreement, the RSUs 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.

(l) Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Participant’s participation in the Plan, on the RSUs, 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.

(m) 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.

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.

(o) 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).

(p) 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.

(q) 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.

(r) 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.

(s) Section 409A of the Code. It is intended that the RSUs granted pursuant to this Agreement and the provisions of this Agreement be exempt from or comply with 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.

(t) 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 RSUs 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.

(u) 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 RSUs 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.

A-8

The Participant understands that Data will be transferred to Fidelity Stock Plan Services, LLC and its affiliates 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 RSUs 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.

(v) 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 RSUs 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 or receives Shares underlying the RSUs 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.

A-10

EUROPEAN UNION (“EU”) / EUROPEAN ECONOMIC AREA (“EEA”) AND THE UNITED KINGDOM

Data Privacy Notice. If the Participant resides and/or works in the EU/EEA or the United Kingdom, the following provision replaces Section 8(u) 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 RSUs, 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 RSUs or any other entitlement to Shares, canceled, exercised, vested, unvested or outstanding in the Participant’s favor] (“Personal Data”). In granting RSUs 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 RSUs 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 RSUs, 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 RSUs, 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.

A-11

(c) International Personal Data Transfers. The Plan and RSUs 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 RSUs, 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.

CANADA

1. Form of Settlement. Notwithstanding any provision in the Plan or Agreement to the contrary, the RSUs will be settled in Shares only, not cash.

2. Securities Law Information. The Participant is permitted to sell Shares acquired under the Plan through the designated broker, if any, provided the resale of such Shares takes place outside of Canada through the facilities of a stock exchange on which the Shares are listed.

3. Separation from Service. The following provision replaces Section 8(i)(x) of the Agreement:

For purposes of the RSUs, the Participant’s service is considered terminated as of the date the Participant is no longer actually employed or otherwise rendering service to the Company or any Affiliate (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment or other laws or the terms of the Participant’s employment or service contract, if any). Unless otherwise extended by the Company or expressly provided in the Agreement, the Participant’s right to vest in the RSUs, if any, will terminate effective as of such date (the “Termination Date”). The Termination Date will not be extended by any common law notice period. Notwithstanding the foregoing, however, if applicable employment standards legislation explicitly requires continued entitlement to vesting during a statutory notice period, the Participant’s right to vest in the RSUs under the Agreement, if any, will be allowed to continue for that minimum notice period but then immediately terminate effective as of the last day of the Participant’s minimum statutory notice period.

In the event the date the Participant is no longer providing actual service cannot be reasonably determined under the terms of this Agreement and/or the Plan, the Company shall have the exclusive discretion to determine when the Participant is no longer actively providing service for purposes of the RSUs (including whether the Participant may still be considered to be providing service while on a leave of absence). Any portion of the RSUs that is not vested on the Termination Date shall terminate immediately and be null and void. Subject to the foregoing, unless the applicable employment standards legislation specifically requires, in the Participant’s case, the Participant will not earn or be entitled to any pro-rated vesting for that portion of time before the date on which the Participant’s service is terminated (as determined under this provision), nor will the Participant be entitled to any compensation for lost vesting.

SINGAPORE

Securities Law Information. The grant of the RSUs 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 RSUs 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 RSUs 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.

SPAIN

1. Acknowledgement of Discretionary Nature of the Plan; No Vested Rights. This provision supplements the terms of the Agreement:

In accepting the RSUs, the Participant acknowledges that he or she consents to participation in the Plan and has received a copy of the Plan.

The Participant understands that the Company has unilaterally, gratuitously and in its sole discretion granted the RSUs under the Plan to individuals who may be employees of the Company and its Affiliates throughout the world. The decision is a limited decision that is entered into upon the express assumption and condition that any grant will not economically or otherwise bind the Company or any of its Affiliates on an ongoing basis. Consequently, the Participant understands that the RSUs are granted on the assumption and condition that the RSUs and the Shares acquired upon settlement of the RSUs shall not become a part of any employment contract (either with the Company or any of its Affiliates) and shall not be considered a mandatory benefit, salary for any purposes (including severance compensation) or any other right whatsoever. In addition, the Participant understands that this grant would not be made to the Participant but for the assumptions and conditions referenced above; thus, the Participant acknowledges and freely accepts that should any or all of the assumptions be mistaken or should any of the conditions not be met for any reason, the grant of the RSUs shall be null and void.

The Participant understands and agrees that, as a condition of the grant of the RSUs, the Participant’s Separation from Service for any reason (including the reasons listed below) will automatically result in the loss of the RSUs to the extent the RSUs has not vested as of date that the Participant ceases active employment. In particular, the Participant understands and agrees that unless otherwise provided in the Agreement, any portion of the RSUs that is unvested as of the date the Participant ceases active employment will be forfeited without entitlement to the underlying Shares or to any amount of indemnification in the event of the termination of employment by reason of, but not limited to, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without cause, individual or collective dismissal on objective grounds, whether adjudged or recognized to be with or without cause, material modification of the terms of employment under Article 41 of the Workers’ Statute, relocation under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, unilateral withdrawal by the Employer and under Article 10.3 of the Royal Decree 1382/1985. The Participant acknowledges that he or she has read and specifically accepts the conditions referred to in the Agreement regarding the impact of a Separation from Service on the Participant’s RSUs.

A-15

2. Securities Law Information. The RSUs and the Shares described in this Agreement do not qualify under Spanish regulations as securities. With respect to the grant of RSUs under the Plan, no “offer of securities to the public,” as defined under Spanish law, has taken place or will take place in the Spanish territory. The Agreement has not been nor will it be registered with the Comisión Nacional del Mercado de Valores, and does not constitute a public offering prospectus.

SWEDEN

Tax Withholding. The following provision shall supplement Section 6 of the Agreement:

Without limiting the Company’s and the Employer’s authority to satisfy their withholding obligations for Tax-Related Items as set forth in the Section 6 of the Agreement, in accepting the grant of the RSUs, the Participant authorizes the Company to withhold Shares otherwise deliverable to the Participant upon settlement of the RSUs or sell Shares issued upon settlement of the RSUs to satisfy Tax-Related Items, regardless of whether the Company and/or the Employer has an obligation to withhold such Tax-Related Items.

UNITED KINGDOM

1. Taxes. This provision shall supplement Section 6 of the Agreement:

Without limitation to Section 6 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 6 of the Agreement.

A-16

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 RSUs, 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 RSUs. Upon the grant of the RSUs, the Participant will be deemed to have waived irrevocably any such entitlement.

Any Participant acquiring Common Stock pursuant to an Option shall be required to pay in full the exercise price related thereto, except as otherwise set forth in a written award agreement with respect to an Option.

5. Administration of the Plan. The Committee shall have the power and authority to prescribe, amend and rescind rules and procedures governing the administration of this Plan, including, but not limited to, the full power and authority (a) to interpret the terms of this Plan, the terms of any Options granted under this Plan and the rules and procedures established by the Committee governing any such Options, (b) to determine the rights of any person under this Plan or the meaning of requirements imposed by the terms of this Plan or any rule or procedure established by the Committee, (c) to correct any defect or omission or reconcile any inconsistency in the Plan or in any Option granted hereunder, (d) to determine whether any Options are subject to and/or comply with the requirements of Code Section 409A or the regulations thereunder and (e) to make all other determinations and take all other actions necessary or advisable for the implementation and administration of the Plan. Each action of the Committee shall be binding on all persons. Notwithstanding any provision to the contrary contained in this Plan or any separate written agreement between the Company and any Participant with respect to any Option pursuant to this Plan, any unvested Options that do not become vested immediately prior to, or in connection with, any Sale of the Company shall be forfeited and cancelled with concurrent effect upon the consummation of any such transaction, and no Participant nor any other Person shall have any further rights or obligations with respect to such forfeited Options.

It is the Company’s intent that, except as otherwise specifically provided in a written award agreement with respect to an Option, the Options not be treated as a nonqualified deferred compensation plan that fails to meet the requirements of Section 409A(a)(2), (3) or (4) of the Code and that any ambiguities in construction be interpreted in order to effectuate such intent. Options under the Plan shall contain such terms as the Committee determines are appropriate to be exempt from, or comply with, the requirements of Section 409A of the Code. In the event that, after the issuance of an Option under the Plan, Section 409A of the Code or the regulations thereunder are amended, or the Internal Revenue Service or Treasury Department issues additional guidance interpreting Section 409A of the Code, the Committee may modify the terms of any such previously issued Option to the extent the Committee determines that such modification is necessary to comply with the requirements of Section 409A of the Code. In no event whatsoever shall the Company be liable for any additional tax, interest or penalty that may be imposed on any Participant by Code Section 409A or damages for failing to comply with Code Section 409A.

6. Limitation on the Aggregate Number of Common Stock. The amount of Common Stock issued under this Plan (including the amount of Common Stock with respect to which Options may be granted under this Plan (and which may be issued upon the exercise or payment thereof)) shall not exceed, in the aggregate, [•] shares (as such number is equitably adjusted pursuant to Section 7 hereof). If any Options expire unexercised or unpaid or are canceled, terminated or forfeited in any manner without the issuance of Common Stock or payment thereunder, the Common Stock with respect to which such Options were granted shall again be available under this Plan. Similarly, if any Common Stock issued hereunder upon exercise of Options are repurchased hereunder, such Common Stock shall again be available under this Plan for reissuance as Options. Common Stock to be issued upon exercise of the Options may be either authorized and unissued Common Stock, treasury shares, or a combination thereof, as the Committee shall determine.

7. Listing, Registration and Compliance with Laws and Regulations. Each Option shall be subject to the requirement that if at any time the Committee shall determine, in its discretion, that the listing, registration or qualification of the Common Stock subject to the Option upon any securities exchange or under any federal, state or foreign securities or other law or regulation, or the consent or approval of any governmental regulatory body, is necessary or

6

desirable as a condition to or in connection with the granting of such Option or the issue or purchase of Common Stock thereunder, no such Option may be exercised or paid in Common Stock in whole or in part unless such listing, registration, qualification, consent or approval (a “Required Listing”) shall have been effected or obtained, and the holder of each such Option will supply the Company with such certificates, representations and information as the Company shall request which are reasonably necessary or desirable in order for the Company to obtain such Required Listing, and shall otherwise cooperate with the Company in obtaining such Required Listing. In the case of officers and other persons subject to Section 16(b) of the Securities Exchange Act of 1934, as amended, the Committee may at any time impose any limitations upon the exercise of an Option which, in the Committee’s discretion, are necessary or desirable in order to comply with Section 16(b) and the rules and regulations thereunder. If the Company, as part of an offering of securities or otherwise, finds it desirable because of federal, state or foreign regulatory requirements to reduce the period during which any Option may be exercised, the Committee may, in its discretion and without the consent of the holders of any such Option, so reduce such period on not less than 15 days’ written notice to the holders thereof.

8. Adjustment for Change in Common Stock. In the event of a reorganization, recapitalization, split, extraordinary dividend, combination of Common Stock, merger, consolidation or other change in Common Stock, the Committee shall make appropriate changes in the number and type of shares authorized by this Plan, the number and type of shares covered by outstanding Options and the exercise prices specified therein.

9. Taxes. The Company shall be entitled, if necessary or desirable, to withhold (or secure payment from the Participant in lieu of withholding) the amount of any withholding or other tax due with respect to any amount payable and/or shares of Common Stock issuable under this Plan, and the Company may defer any such payment or issuance unless and until indemnified to its satisfaction.

10. Termination and Amendment. The Committee at any time may suspend or terminate this Plan and make such additions or amendments as it deems advisable under this Plan, except that it may not, without further approval by the Company’s Members, (a) increase the maximum number of shares as to which Options may be granted under this Plan, except pursuant to Section 7 above or (b) extend the term of this Plan; provided, that, subject to the other provisions hereof, the Committee may not change any of the terms of a written agreement with respect to an Option between the Company and the holder of such Option in a manner which would have a material adverse effect on the holder of such Option without the approval of the holder of such Option. No Options shall be granted or shares of Common Stock issued hereunder after the tenth anniversary of the Effective Date.

11. Participant Acknowledgments. In connection with the grant of any Option and/or the issuance of any Common Stock pursuant to this Plan, each Participant acknowledges and agrees, that as a condition to any such grant or issuance:

(a) The Company will have no duty or obligation to disclose to any Participant, and no Participant will have any right to be advised of, any material information regarding the Company or its Subsidiaries at any time prior to, upon or in connection with the repurchase of any Option Shares upon the termination of such Participant’s employment with the Company or its Subsidiaries or as otherwise provided under this Plan or any written agreement evidencing the grant of any Option or the issuance of any shares of Common Stock.

7

(b) Neither the grant of any Option, the issuance of any Common Stock nor any provision contained in this Plan or in any written agreement evidencing the grant of any Option or the issuance of any Common Stock shall entitle such Participant to remain in the employment of the Company or its Subsidiaries or affect the right of the Company to terminate any Participant’s employment at any time for any reason.

(c) Such Participant will have consulted, or will have had an opportunity to consult with, independent legal counsel regarding his or her rights and obligations under this Plan and any written agreement evidencing any grant of any Option or the issuance of any Common Stock and he or she fully understands the terms and conditions contained herein and therein.

(d) Prior to the purchase of any shares of Common Stock pursuant to this Plan or any written agreement evidencing the purchase of any shares of Common Stock, such Participant will deliver to the Company an executed consent from such Participant’s spouse (if any) in the form of Exhibit 1 attached hereto. If, at any time subsequent to the date such Participant purchases any shares of Common Stock and prior to the occurrence of a Termination Event, such Participant becomes legally married (whether in the first instance or to a different spouse), such Participant shall cause his or her spouse to execute and deliver to the Company a consent in the form of Exhibit 1 attached hereto. Such Participant’s failure to deliver the Company an executed consent in the form of Exhibit 1 at any time when such Participant would otherwise be required to deliver such consent shall constitute such Participant’s continuing representation and warranty that such Participant is not legally married as of such date.

12. Definition of Option Shares. For all purposes of this Plan, Option Shares will continue to be Option Shares in the hands of any holder other than such Participant (except for the Company, the Investors or purchasers pursuant to an offering registered under the Securities Act or purchasers pursuant to a Rule 144 transaction (other than a Rule 144(k) transaction occurring prior to the time of a closing of an IPO)), and each such other holder of Option Shares will succeed to all rights and obligations attributable to such Participant as a holder of Option Shares hereunder and under any separate written agreement between the Company and such Participant. Option Shares will also include shares of the Company’s shares issued with respect to Option Shares by way of a split, dividend or other recapitalization.

13. Transfers in Violation of Plan. Any transfer or attempted transfer of any Option Shares in violation of any provision of this Plan shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such Option Shares as the owner of such Common Stock for any purpose.

14. Severability. Whenever possible, each provision of this Plan will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Plan is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Plan will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

8

Exhibit 10.7

INTEGRAL AD SCIENCE HOLDING CORP.

AMENDED AND RESTATED STOCK OPTION AGREEMENT

This AMENDED AND RESTATED STOCK OPTION AGREEMENT (this “Agreement”) is made and entered into as of [●] (the “Grant Date”), between Integral Ad Science Holding Corp., a Delaware corporation (the “Company”), and [●] (“Optionholder”).

The Company and Optionholder desire to enter into this Agreement whereby the Company will grant Optionholder the options specified herein to acquire certain Common Stock of the Company. The options to acquire the Common Stock are sometimes hereinafter referred to individually as an “Option” and collectively as the “Options”. All Common Stock issuable upon the exercise of any portion of the Options and all stock of the Company’s equity securities hereafter acquired by Optionholder are referred to herein as “Option Shares”. Defined terms used in this Agreement without definition will have the meanings ascribed thereto in the Company’s Amended and Restated 2018 Non-Qualified Stock Option Plan (the “Plan”), a copy of which is attached hereto as Exhibit A. In the event a provision of this Agreement is inconsistent or conflicts with the provisions of the Plan, the provisions of this Agreement will govern and prevail.

The parties hereto agree as follows:

1.    Plan Acknowledgment. Each of the undersigned agree that this Agreement has been executed and delivered, and the stock options have been granted hereunder, in connection with and as a part of the compensation and incentive arrangements between the Company and Optionholder and, except as otherwise specified herein, pursuant to, and subject to, each of the terms and conditions of the Plan, and Optionholder agrees to be bound by, and comply with, the terms of the Plan.

2.    Options.

(a)    Service Option Grant. The Company hereby grants to Optionholder, pursuant to the Plan, an option to purchase up to [●] shares of Common Stock (the “Service Option”, and such shares, the “Service Option Shares”), at an exercise price per unit of $[●] (the “Option Price”). The Option Price and the number of Service Option Shares issuable upon exercise of any Service Option will be equitably adjusted for any split, dividend or reclassification of Common Stock, which occurs subsequent to the date of this Agreement. The Service Option will expire as provided in Section 2(d) below. The Service Option is not intended to be an “incentive stock option” within the meaning of Section 422 of the Code. The “Vesting Commencement Date” for purposes of this Agreement is [●].

(b)    Return Target Option Grant. The Company hereby grants to Optionholder, pursuant to the Plan, an option to purchase up to [●] shares of Common Stock (the “Return Target Option”, and such shares, the “Return Target Option Shares”), at an exercise price per unit equal to the Option Price. The Option Price and the number of Return Target Option Shares issuable upon exercise of any Return Target Options will be equitably adjusted for any split, dividend or reclassification of Common Stock which occurs subsequent to the date of this Agreement. The Return Target Options will expire as provided in Section 2(d) below. The Return Target Options are not intended to be “incentive stock options” within the meaning of Section 422 of the Code.

(c)    Exercisability. Options shall become vested and exercisable in accordance with the provisions of this Section 2(c) and Section 2(f) below. Options which have become vested as of the date of determination are referred to herein as “Vested Options”, and all other Options are referred to herein as “Unvested Options”. Optionholder may only exercise Options that are Vested Options.

(i)    Service Options. The Service Options described in Section 2(a) above will have vested and become exercisable with respect to twenty-five percent (25%) of the Service Option Shares underlying the Service Options on the twelve (12) month anniversary of the Vesting Commencement Date (the “First Vesting Date”) if Optionholder remains in the continuous employ of or service with the Company or any of its Subsidiaries from and after the date hereof through and including such date, and with respect to an additional 6.25% of the Service Option Shares at the end of each full three calendar month period after the First Vesting Date if, Optionholder is, and has been, continuously employed by the Company or its Subsidiaries from the date of this Agreement through such date.

(ii)    Return Target Options. The Return Target Options will have vested and become exercisable if (A) Optionholder is, and has been, continuously employed by the Company or its Subsidiaries from the date of this Agreement through the date of a Termination Event and (B) if upon the consummation of such Termination Event, 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) 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 (the “Vesting Condition”). As used in this Agreement, the term “Investor Fund” shall mean one or more equity buy-out investment funds (including Vista Equity Partners Fund VI, L.P., Vista Equity Partners Fund VI-A, L.P. and VEPF VI FAF, L.P.) managed or controlled by Vista Equity Partners Management, LLC 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. For purposes of calculating distributions and proceeds under clause (B) immediately above,, all distributions made to the Investor Funds 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) and receipt of any applicable proceeds payable with respect to the holder (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 the Termination Event.

(d)    Expiration of Options. Notwithstanding any provision herein to the contrary, any portion of the Options granted hereunder that have not vested and become exercisable prior to the Termination Date will expire on the Termination Date and may not be exercised under any circumstance. Any portion of the Options granted hereunder that have vested

2

and become exercisable prior to the Termination Date will expire on the earlier of (i) 30 days after the Termination Date and (ii) the close of business on the tenth anniversary of the date of this Agreement. Notwithstanding any provision in this Agreement to the contrary, any portion of the Options granted hereunder which have not been or are not exercised prior to or in connection with a Termination Event, as described in clauses (i) or (ii) of such definition, shall expire upon the consummation of any such transaction.

(e)    Procedure for Exercise. At the time after any portion of the Options granted hereunder have become vested and exercisable with respect to any Option Shares and prior to the expiration of any such Options, Optionholder may exercise any portion of the Options granted hereunder with respect to Option Shares vested and exercisable pursuant to Section 2(c) above by delivering written notice of exercise to the Company, together with (i) a written acknowledgment that Optionholder has read and has been afforded an opportunity to ask questions of management of the Company regarding all financial and other information provided to Optionholder regarding the Company and its Subsidiaries, (ii) payment in full by delivery of a cashier’s, personal or certified check or wire transfer of immediately available funds to the Company, in the amount equal to the number of Option Shares to be acquired multiplied by the applicable option exercise price (the “Aggregate Exercise Price”); provided that, Optionholder may, in lieu of paying the Aggregate Exercise Price in cash, indicate in Optionholder’s exercise notice that such Optionholder intends to effect a cashless exercise thereof and, in such case, the Company shall cancel such number of Option Shares otherwise issuable to Optionholder having a Fair Market Value equal to the Aggregate Exercise Price of the Options being exercised, in which event the Company shall only issue Option Shares for the remainder of the Options being exercised after satisfying the Aggregate Exercise Price, and (iii) an executed consent from Optionholder’s spouse (if any) in the form of Exhibit 1 attached to the Plan. As a condition to any exercise of the Options, Optionholder will permit the Company to deliver to him or her all financial and other information regarding the Company and its Subsidiaries which it believes is necessary to enable Optionholder to make an informed investment decision. If, at any time subsequent to the date Optionholder exercises any portion of the Options granted hereunder and prior to the occurrence of a Termination Event, Optionholder becomes legally married (whether in the first instance or to a different spouse), Optionholder shall cause Optionholder’s spouse to execute and deliver to the Company a consent in the form of Exhibit 1 attached to the Plan. Optionholder’s failure to deliver to the Company an executed consent in the form of Exhibit 1 to the Plan at any time when Optionholder would otherwise be required to deliver such consent shall constitute Optionholder’s continuing representation and warranty that Optionholder is not legally married as of such date.

(f)    Termination Event. Immediately prior to the consummation of a Termination Event, any Service Options which were Unvested Options immediately prior to such Termination Event shall be deemed Vested Options (such Options which are subject to accelerated vesting being referred to as the “Accelerated Options”). Optionholder hereby agrees that upon a Termination Event, the Accelerated Options shall be deemed to be automatically exercised through a cashless exercise and Optionholder 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 Optionholder (whether in the form of cash or stock) in respect of such deemed exercise of the Accelerated Options as of the Termination Event.

3

(g)    Securities Laws Restrictions. Optionholder represents that when Optionholder exercises any portion of the Options he or she will be purchasing the Option Shares represented thereby for Optionholder’s own account and not on behalf of others. Optionholder understands and acknowledges that federal, state and foreign securities laws govern and restrict Optionholder’s right to offer, sell or otherwise dispose of any Option Shares unless Optionholder’s offer, sale or other disposition thereof is registered under the Securities Act and federal, state and foreign securities laws or, in the opinion of the Company’s counsel, such offer, sale or other disposition is exempt from registration thereunder. Optionholder agrees that he or she will not offer, sell or otherwise dispose of any Option Shares in any manner which would: (i) require the Company to file any registration statement (or similar filing under applicable securities law) with the Securities and Exchange Commission or to amend or supplement any such filing or (ii) violate or cause the Company to violate the Securities Act, the rules and regulations promulgated thereunder or any other applicable securities law. Optionholder further understands that the certificates (if any) for any Option Shares which Optionholder purchases will bear the legend set forth in the Plan or such other legends as the Company deems necessary or desirable in connection with the Securities Act or other rules, regulations or laws.

(h)    Code Section 409A Compliance. The Company may reduce or expand the period of time following an event in which the vested portion of the Options may be exercised if Internal Revenue Service guidance specifies that such a reduction is required or that such an expansion is permitted under the provisions of Section 409A(a)(2) of the Code. In addition, the Company may (but shall be under no obligation to) make any other changes to this Agreement it determines are necessary to comply with the provisions of Section 409A(a)(2) of the Code. Optionholder hereby agrees and acknowledges, neither the Company nor any of its affiliates makes any representations with respect to the application of Section 409A of the Code to the Options and, by the acceptance of the Options, Optionholder agrees to accept the potential application of Section 409A of the Code to the Option and the other tax consequences of the issuance, vesting, ownership, modification, adjustment, exercise and disposition of the Options.

(i)    Withholding of Taxes. The Company shall be entitled, if necessary or desirable, to withhold from Optionholder from any amounts due and payable by the Company to Optionholder (or secure payment from Optionholder in lieu of withholding) the amount of any withholding or other tax due from the Company with respect to any Options or Common Stock issuable under this Agreement.

(j)    Limited Transferability of the Options. The Options granted hereunder are personal to Optionholder and are not transferable by Optionholder except pursuant to the laws of descent or distribution. Only Optionholder or his or her legal guardian or representative may exercise the Options granted hereunder.

3.    Optionholder’s Representations. Optionholder hereby represents and warrants to the Company that (a) the execution, delivery and performance of this Agreement by Optionholder does not and will not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Optionholder is a party or by which he or she is bound, (b) Optionholder is not a party to or bound by any employment agreement, noncompete agreement or confidentiality agreement with any other person or entity (other than the Company or one of its Subsidiaries) and (c) upon the execution and delivery of this Agreement by the

4

Company and Optionholder, this Agreement shall be the valid and binding obligation of Optionholder, enforceable against Optionholder in accordance with its terms. Optionholder hereby acknowledges and represents that he or she has consulted with (or has had an opportunity to consult with) independent legal counsel regarding his or her rights and obligations under this Agreement (including, without limitation, the Plan) and that he or she fully understands the terms and conditions contained herein and therein.

4.    Notices. Any notices required or permitted under this Agreement or the Plan will be delivered in accordance with the requirements of the Plan.

5.    Third Party Beneficiaries; Successors and Assigns. The parties hereto acknowledge and agree that the Investor Funds are third party beneficiaries of this Agreement and the Plan. Except as otherwise provided herein, this Agreement and the Plan shall bind and inure to the benefit of and be enforceable by Optionholder, the Company and the Investor Funds and their respective heirs, successors and assigns (including subsequent holders of Option Shares); provided that the rights and obligations of Optionholder under this Agreement and the Plan shall not be assignable except as permitted by Section 2(j) or in connection with a permitted transfer of Option Shares in accordance with the Plan.

6.    Section 83(b) Election. Within 30 days after Optionholder has exercised any portion of the Option, in the event Optionholder is subject to United States federal income tax, Optionholder may, and is advised to, make an effective election with the Internal Revenue Service under Section 83(b) of the Code (an “83(b) Election”) relative to the Option Shares received by Optionholder pursuant to the exercise of such portion of the Option. Optionholder further acknowledges and understands that it is Optionholder’s sole obligation and responsibility to timely file such 83(b) Election, and neither the Company nor the Company’s legal or financial advisors shall have (i) any obligation or responsibility with respect to such filing or (ii) any liability resulting or arising from the failure to timely file such 83(b) Election.

7.    Complete Agreement. This Agreement and the Plan and the other documents referred to herein and therein embody the complete agreement and understanding among the parties and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

[Attached]

Exhibit 10.8

INDEMNIFICATION AGREEMENT

THIS INDEMNIFICATION AGREEMENT (this “Agreement”) is made and entered into as of [•], 2021, between Integral Ad Science Holding Corp., a Delaware corporation (the “Company”), and [                ] (“Indemnitee”).

WHEREAS, highly competent persons have become more reluctant to serve corporations as directors or officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation;

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the corporation or business enterprise itself. The Bylaws of the Company (as amended or restated, the “Bylaws”) require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (“DGCL”). The Bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the Board, officers of the Company and other persons with respect to indemnification;

WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such persons;

WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future;

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified;

WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws and any resolutions adopted pursuant thereto, as well as any rights of Indemnitee under any director’s or officer’s liability insurance policy, and this Agreement shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; [and]

WHEREAS, Indemnitee does not regard the protections available under the Bylaws and insurance as adequate in the present circumstances, and may not be willing to serve or continue to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve or continue to serve in such capacity; Indemnitee is willing to serve, continue to serve and take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified[.][; and]

[WHEREAS, Indemnitee has certain rights to indemnification and/or insurance provided by Vista Equity Partners (“Vista”) or affiliates of Vista which Indemnitee and Vista intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgment of and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board.]

NOW, THEREFORE, in consideration of Indemnitee’s agreement to serve as a director or officer from and after the date hereof, the parties hereto agree as follows:

1. Indemnity of Indemnitee. Subject to the provisions of Section 9, the Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time, if Indemnitee was or is, or is threatened to be made, a party to, or otherwise becomes involved in, any Proceeding (as hereinafter defined) by reason of Indemnitee’s Corporate Status (as hereinafter defined). In furtherance of the foregoing indemnification, and without limiting the generality thereof:

(a) Proceedings other than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section l(a) if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant, or otherwise becomes involved in, in any Proceeding (as hereinafter defined) other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe Indemnitee’s conduct was unlawful. The parties hereto intend that this Agreement shall provide to the fullest extent permitted by law for indemnification in excess of that expressly permitted by statute, including, without limitation, any indemnification provided by the Certificate of Incorporation, the Bylaws, vote of the Company’s stockholders or Disinterested Directors or otherwise.

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section 1(b) if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best

2

interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company unless and only to the extent that the court in which the Proceeding was brought shall determine, upon application that, despite the adjudication of liability but in view of all the circumstances of the case, that Indemnitee is fairly and reasonably entitled to indemnification.

(c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a party to or participant in and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, Indemnitee shall be indemnified to the maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section 1(c) and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

2. Additional Indemnity. In addition to, and without regard to any limitations on the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does, to the fullest extent permitted by applicable law, indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf if, by reason of Indemnitee’s Corporate Status, in connection with any Proceeding (including a Proceeding by or in the right of the Company) that Indemnitee is, or is threatened to made, a party to, or participant in. The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement, other than those set forth in Section 9 hereof, shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful.

3. Contribution.

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending or completed Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), to the fullest extent permitted by applicable law, the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not, without the Indemnitee’s prior written consent, enter into any such settlement of any Proceeding (in whole or in part) unless such settlement (i) provides for a full and final release of all claims asserted against Indemnitee and (ii) does not impose any Expense, judgment, fine, penalty or limitation on Indemnitee.

3

(b) Without diminishing or impairing the obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), to the fullest extent permitted by applicable law, the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which the law may require to be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is active or passive.

(c) To the fullest extent permitted by applicable law, the Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee.

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness, is made (or asked) to respond to discovery requests, or is otherwise asked to participate, in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith.

5. Advancement of Expenses. Notwithstanding any other provision of this Agreement (other than Section 7(d)), the Company shall advance, to the extent not prohibited by law, all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding (or part of any Proceeding) not initiated by Indemnitee or any Proceeding initiated by Indemnitee with the prior approval of the Board as provided in Section 9(d), within thirty (30) days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee.

Any advances pursuant to this Section 5 shall be unsecured and interest free and shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. In accordance with Section 7(d) hereof, advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. The Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that the Indemnitee undertakes to repay the amounts advanced (without interest) by the Company pursuant to this Section 5, if and only to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. No other form of undertaking shall be required other than the execution of this Agreement. This Section 5 shall not apply to claim by Indemnitee for Expenses in a matter for which indemnity and advancement of Expenses is excluded pursuant to Section 9 hereof.

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement:

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially prejudices the interests of the Company.

(b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board: (1) by a majority vote of the Disinterested Directors (as hereinafter defined), even though less than a quorum; (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum; (3) if there are no Disinterested Directors, or if the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or (4) if so directed by the Board, by the stockholders of the Company; provided, however, that if a Change in Control has occurred, the determination with respect to Indemnitee’s entitlement to indemnification shall be made by Independent Counsel.

5

(c) In the event the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be selected as provided in this Section 6(c). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the Board, and the Company shall give written notice to the Indemnitee advising Indemnitee of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined (as defined below), and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the Person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or the Chancery Court of the State of Delaware (the “Delaware Court”) has determined that such objection is without merit. If (i) an Independent Counsel is to make the determination of entitlement pursuant to this Section 6, and (ii) within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected (including as a result of an objection to the selected Independent Counsel), either the Company or Indemnitee may petition the Delaware Court or other court of competent jurisdiction for resolution of any objection which shall have been made by Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a Person selected by the court or by such other Person as the court shall designate, and the Person with respect to whom all objections are so resolved or the Person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed.

(d) In making a determination with respect to entitlement to indemnification hereunder, the Person making such determination shall to the fullest extent permitted by law presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof to overcome such presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct.

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified

6

public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

(f) If the Person empowered or selected under this Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall to the fullest extent permitted by law be deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the Person making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) hereof and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat.

(g) Indemnitee shall cooperate with the Person making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such Person upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including reasonable attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the Person making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall to the fullest extent permitted by law be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

7

(i) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.

7. Remedies of Indemnitee.

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant to Section 6(b) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, or (v) the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification, contribution or advancement of Expenses. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration.

(b) In the event that a determination shall have been made pursuant to Section 6(b) hereof that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b) hereof. In any judicial proceeding or arbitration commenced pursuant to this Section 7, Indemnitee shall be presumed to be entitled to indemnification under this Agreement and the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 6(b) hereof adverse to Indemnitee for any purpose other than to establish its compliance with the terms of this Agreement. If Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 7, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 5 hereof until a final determination is made with respect to Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed).

8

(c) If a determination shall have been made pursuant to Section 6(b) hereof that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading, in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law.

(d) In the event that Indemnitee, pursuant to this Section 7, incurs costs, in a judicial or arbitration proceeding or otherwise, attempting to enforce Indemnitee’s rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on Indemnitee’s behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 12 hereof) actually and reasonably incurred by Indemnitee in such efforts, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery, to the fullest extent permitted by applicable law. It is the intent of the Company that, to the fullest extent permitted by applicable law, Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. The Company shall, to the fullest extent permitted by law, indemnify Indemnitee against any and all Expenses in connection with any action brought by Indemnitee for indemnification or advancement of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company if Indemnitee is wholly successful on the underlying claims; if Indemnitee is not wholly successful on the underlying claims, then such indemnification shall be only to the extent Indemnitee is successful on such underlying claims or otherwise as permitted by law, whichever is greater.

(e) The Company shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement.

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding.

9

8. Non-Exclusivity; Survival of Rights; [Primacy of Indemnification;] Insurance; Subrogation.

(a) The rights of indemnification and to receive advancement of Expenses as provided by this Agreement (i) shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation of the Company (as amended or restated, the “Charter”), the Bylaws, any agreement, a vote of stockholders, a resolution of directors or otherwise, of the Company and (ii) shall be interpreted independently of, and without reference to, any other such rights to which Indemnitee may at any time be entitled. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Charter, Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy.

(b) The Company shall, if commercially reasonable, obtain and maintain in effect during the entire period for which the Company is obligated to indemnify Indemnitee under this Agreement, one or more policies of insurance with reputable insurance companies to provide the directors and officers of the Company with coverage for losses from wrongful acts and omissions and to ensure the Company’s performance of its indemnification obligations under this Agreement. Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such officer or director under such policy or policies. In all such insurance policies, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee with the same rights and benefits as are accorded to the most favorably insured of the Company’s directors and officers. At the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies.

(c) [The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by Vista and certain affiliates that, directly or indirectly, (i) are controlled by, (ii) control or (iii) are under common control with, Vista (collectively, the “Fund Indemnitors”). With respect to any amounts that are subject to indemnity under this Agreement and also subject to an indemnity obligation owed by Fund Indemnitors, the Company hereby agrees (i) that, as compared the Fund Indemnitors, it is the indemnitor of first resort with respect to any rights to indemnification provided to Indemnitee herein (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee is secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Charter or Bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to

10

any rights Indemnitee may have against the Fund Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 8(c).]

(d) [Except as provided in Section 8(c) above,] in the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [(other than against the Fund Indemnitors)], who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

(e) [Except as provided in Section 8(c) above,] the Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable (or for which advancement of Expenses is provided) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

(f) [Except as provided in Section 8(c) above,] the Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnity or advancement of Expenses in connection with any claim involving Indemnitee:

(a) for which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; [provided, that the foregoing shall not affect the rights of Indemnitee or the Fund Indemnitors set forth in Section 8(c) above;] or

(b) for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act (as hereinafter defined), or similar provisions of state statutory law or common law; or

11

(c) for reimbursement to the Company of any bonus or other incentive-based or equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Company in each case as required under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) or Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act in connection with an accounting restatement of the Company or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act);

(d) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Company has joined in or the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation, (ii) such payment arises in connection with any mandatory counterclaim or cross claim brought or raised by Indemnitee in any Proceeding (or any part of any Proceeding), (iii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, or (iv) the Proceeding is one to enforce Indemnitee’s rights under this Agreement or;

(e) any reimbursement of the Company by Indemnitee of any compensation pursuant to any compensation recoupment or clawback policy adopted by the Board or the compensation committee of the Board, including but not limited to any such policy adopted to comply with stock exchange listing requirements implementing Section 10D of the Exchange Act.

10. Non-Disclosure of Payments. Except as expressly required by applicable law, neither party shall disclose any payments under this Agreement unless prior approval of the other party is obtained. If any payment information must be disclosed, the Company shall afford the Indemnitee an opportunity to review all such disclosures and, if requested, to explain in such statement any mitigating circumstances regarding the events to be reported.

11. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue until and terminate upon the later of (i) ten (10) years after the date that Indemnitee shall have ceased to serve as a director or officer of the Company or a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which Indemnitee served at the request of the Company, and (ii) one (1) year after the final termination of any Proceeding (including any rights of appeal thereto) in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any Proceeding commenced by Indemnitee pursuant to Section 7 hereof relating thereto (including any rights of appeal of any such Proceeding). Termination of this Agreement shall not adversely affect any right or protection hereunder of any Indemnitee in respect of any Proceeding (regardless of when such Proceeding is first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to the time of such termination. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives and shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or of any other Enterprise at the Company’s request.

12

The parties agree that for the purposes of

14

any advancement of Expenses for which Indemnitee has made written demand to the Company in accordance with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable in the good faith judgment of such counsel shall be presumed conclusively to be reasonable. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee.

(h) “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five (5) years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder.

If Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be considered a Proceeding under this definition.]

13. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality, and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (ii) such provision or provisions shall be deemed reformed

to the fullest extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (iii) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws.

14. Enforcement and Binding Effect.

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving or continuing to serve as a director or officer of the Company.

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Charter, the Bylaws, any directors’ and officers’ insurance maintained by the Company and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder.

(c) The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

(d) The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate, impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto agree that Indemnitee may enforce this Agreement by seeking injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining any other relief to which Indemnitee may be entitled. The Company and Indemnitee further agree that Indemnitee shall be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by the court, and the Company hereby waives any such requirement of such a bond or undertaking.

16

15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

16. Notice By Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The failure to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay materially prejudices the Company.

17. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified, (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business day, (iii) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (iv) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.

Exhibit 10.9

DIRECTOR NOMINATION AGREEMENT

THIS DIRECTOR NOMINATION AGREEMENT (this “Agreement”) is made and entered into as of [●], 2021, by and among Integral Ad Science Holding Corp., a Delaware corporation (the “Company”), Vista Equity Partners Fund VI, L.P., Vista Equity Partners Fund VI-A, L.P., VEPF VI FAF, L.P., Vista Equity Partners Fund VI GP, L.P., VEPF VI GP, Ltd., and VEP Group, LLC (collectively, “Vista”). This Agreement shall be effective from the date hereof (the “Effective Date”).

WHEREAS, as of the date hereof, Vista beneficially owns a majority of the equity interests in the Company;

WHEREAS, Vista is contemplating causing the Company to effect an initial public offering (the “IPO”);

WHEREAS, Vista currently has the authority to appoint all directors of the Company;

WHEREAS, in consideration of Vista agreeing to undertake the IPO, the Company has agreed to permit Vista to designate persons for nomination for election to the board of directors of the Company (the “Board”) following the Effective Date on the terms and conditions set forth herein;

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of the parties to this Agreement agrees as follows:

1. Board Nomination Rights.

(a) From the Effective Date, Vista shall have the right, but not the obligation, to nominate to the Board a number of designees equal to at least: (i) 100% of the Total Number of Directors (as defined below), so long as Vista Beneficially Owns shares of common stock, par value $0.001 per share (the “Common Stock”) representing at least 40% of the Original Amount of Vista, (ii) 40% of the Total Number of Directors, in the event that Vista Beneficially Owns shares of Common Stock representing at least 30% but less than 40% of the Original Amount of Vista, (iii) 30% of the Total Number of Directors, in the event that Vista Beneficially Owns shares of Common Stock representing at least 20% but less than 30% of the Original Amount of Vista, (iv) 20% of the Total Number of Directors, in the event that Vista Beneficially Owns shares of Common Stock representing at least 10% but less than 20% of the Original Amount of Vista and (v) one Director, in the event that Vista Beneficially Owns shares of Common Stock representing at least 5% of the Original Amount of Vista (such persons, the “Nominees”). For purposes of calculating the number of directors that Vista is entitled to designate pursuant to the immediately preceding sentence, any fractional amounts shall automatically be rounded up to the nearest whole number (e.g., 1¹⁄₄ Directors shall equate to 2 Directors) and any such calculations shall be made after taking into account any increase in the Total Number of Directors.

(b) In the event that Vista has nominated less than the total number of designees Vista shall be entitled to nominate pursuant to Section 1(a), Vista shall have the right, at any time, to nominate such additional designees to which it is entitled, in which case, the Company and the Directors shall take all necessary corporation action (including increasing the size of the Board to create a vacancy), to the fullest extent permitted by applicable law (including with respect to fiduciary duties under Delaware law), to (x) enable Vista to nominate and effect the election or appointment of such additional individuals, whether by increasing the size of the Board, or otherwise and (y) to designate such additional individuals nominated by Vista to fill such newly created vacancies or to fill any other existing vacancies.

(c) In addition to the nomination rights set forth in Section 1(a) above, from the Effective Date, for so long as Vista Beneficially Owns shares of Common Stock representing at least 5% of the Original Amount of Vista, Vista shall have the right, but not the obligation, to designate a person (a “Non-Voting Observer”) to attend meetings of the Board (including any meetings of any committees thereof) in a non-voting observer capacity. Any such Non-Voting Observer shall be permitted to attend all meetings of the Board. Vista shall have the right to remove and replace its Non-Voting Observer at any time and from time to time. The Company shall furnish to any Non-Voting Observer (i) notices of Board meetings no later than, and using the same form of communication as, notice of Board meetings are furnished to directors and (ii) copies of any materials prepared for meetings of the Board that are furnished to the directors no later than the time such materials are furnished to the directors; provided that failure to deliver notice, or materials, to such Non-Voting Observer in connection with such Non-Voting Observer’s right to attend and/or review materials with respect to, any meeting of the Board shall not, by itself, impair the validity of any action taken by such Board at such meeting. Such Non-Voting Observer shall be required to execute or otherwise become subject to any codes of conduct or confidentiality agreements of the Company generally applicable to directors of the Company or as the Company reasonably requests. Notwithstanding the foregoing, the Company reserves the right to withhold any information and to exclude the Non-Voting Observer from receiving any materials and/or attending any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel.

(d) The Company shall pay all reasonable out-of-pocket expenses incurred by the Nominees and the Non-Voting Observer in connection with the performance of his or her duties as a director or a Non-Voting Observer and in connection with his or her attendance at any meeting of the Board.

(e) “Affiliate” of any person shall mean any other person controlled by, controlling or under common control with such person; where “control” (including, with its correlative meanings, “controlling,” “controlled by” and “under common control with”) means possession, directly or indirectly, of power to direct or cause the direction of management or policies (whether through ownership of securities, by contract or otherwise).

(f) “Beneficially Own” shall mean that a specified person has or shares the right, directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, to vote shares of capital stock of the Company.

2

(g) “Director” means any member of the Board.

(h) “Original Amount of Vista” means the aggregate number of shares of Common Stock held, directly or indirectly, by Vista on the date hereof, as such number may be adjusted from time to time for any reorganization, recapitalization, stock dividend, stock split, reverse stock split or other similar changes in the Company’s capitalization.

(i) “Total Number of Directors” means the total number of Directors comprising the Board.

(j) No reduction in the number of shares of Common Stock that Vista Beneficially Owns shall shorten the term of any incumbent director. At the Effective Date, the Board shall be comprised of nine members including Michael Fosnaugh, Rod Aliabadi, Martin Taylor, Brooke Nakatsukasa, Lisa Utzschneider, Jill Putman, Otto Berkes and Bridgette Heller, and Christina Lema as the director nominee to be approved as of the Effective Date.

(k) In the event that any Nominee shall cease to serve for any reason, Vista shall be entitled to designate such person’s successor in accordance with this Agreement (regardless of Vista’s beneficial ownership in the Company at the time of such vacancy) and the Board shall promptly fill the vacancy with such successor nominee; it being understood that any such designee shall serve the remainder of the term of the director whom such designee replaces.

(l) If a Nominee is not appointed or elected to the Board because of such person’s death, disability, disqualification, withdrawal as a nominee or for other reason is unavailable or unable to serve on the Board, Vista shall be entitled to designate promptly another nominee and the director position for which the original Nominee was nominated shall not be filled pending such designation.

(m) So long as Vista has the right to nominate Nominees under Section 1(a) or any such Nominee is serving on the Board, the Company shall use its reasonable best efforts to maintain in effect at all times directors and officers indemnity insurance coverage reasonably satisfactory to Vista, and the Company’s Certificate of Incorporation and Bylaws (each as may be further amended, supplemented or waived in accordance with its terms) shall at all times provide for indemnification, exculpation and advancement of expenses to the fullest extent permitted under applicable law.

(n) If the size of the Board is expanded, Vista shall be entitled to nominate a number of Nominees to fill the newly created vacancies such that the total number of Nominees serving on the Board following such expansion will be equal to that number of Nominees that Vista would be entitled to nominate in accordance with Section 1(a) if such expansion occurred immediately prior to any meeting of the stockholders of the Company called with respect to the election of members of the Board, and the Board shall appoint such Nominees to the Board.

(o) At such time as the Company ceases to be a “controlled company” and is required by applicable law or NASDAQ Global Select Market (the “Exchange”) listing standards to have a majority of the Board comprised of “independent directors” (subject in each case to any applicable

3

phase-in periods), Vista’s Nominees shall include a number of persons that qualify as “independent directors” under applicable law and the Exchange listing standards such that, together with any other “independent directors” then serving on the Board that are not Nominees, the Board is comprised of a majority of “independent directors.”

(p) At any time that Vista shall have any nomination rights under Section 1, the Company shall not take any action, including making or recommending any amendment to the Certificate of Incorporation or the Company’s Bylaws that could reasonably be expected to adversely affect Vista’s rights under this Agreement, in each case without the prior written consent of Vista.

(q) The Company recognizes that each Nominee (i) will from time to time receive non-public information concerning the Company, and (ii) may share such information with other individuals associated with Vista that designated such Nominee. The Company hereby irrevocably consents to such sharing. Vista agrees that it will keep confidential and not disclose or divulge to any third party any confidential information regarding the Company it receives from the Company or a Nominee, unless such information (x) is available or becomes available to the public in general, (y) is or has been independently developed or conceived by Vista without use of the Company’s confidential information or (z) is or has been made known or disclosed to Vista by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that Vista may disclose confidential information (I) to its Affiliates (other than portfolio companies), (II) to each of its and its Affiliate’s (other than portfolio companies) attorneys, accountants, consultants, advisors and other professionals to the extent necessary to obtain their services in connection with evaluating the information, or (III) as may be required by law or legal, judicial or regulatory process or requested by any regulatory or self-regulatory authority or examiner, provided that Vista takes reasonable steps to minimize the extent of any required disclosure described in this clause (III)

2. Company Obligations. The Company agrees to use its reasonable best efforts to ensure that prior to the date that Vista and its Affiliates cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, (i) each Nominee is included in the Board’s slate of nominees to the stockholders (the “Board’s Slate”) for each election of directors; and (ii) each Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of the Board (each, a “Director Election Proxy Statement”), and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board. Vista will promptly provide reporting to the Company after Vista ceases to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, such that Company is informed of when this obligation terminates. The calculation of the number of Nominees that Vista is entitled to nominate to the Board’s Slate for any election of directors shall be based on the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by Vista (“Vista Voting Control”) immediately prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange

4

Commission). Unless Vista notifies the Company otherwise prior to the mailing to shareholders of the Director Election Proxy Statement relating to an election of directors (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), the Nominees for such election shall be presumed to be the same Nominees currently serving on the Board, and no further action shall be required of Vista for the Board to include such Nominees on the Board’s Slate; provided, that, in the event Vista is no longer entitled to nominate the full number of Nominees then serving on the Board, Vista shall provide advance written notice to the Company, of which currently servicing Nominee(s) shall be excluded from the Board Slate, and of any other changes to the list of Nominees. If Vista fails to provide such notice prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), a majority of the independent directors then serving on the Board shall determine which of the Nominees of Vista then serving on the Board will be included in the Board’s Slate. Furthermore, the Company agrees for so long as the Company qualifies as a “controlled company” under the rules of the Exchange the Company will elect to be a “controlled company” for purposes of the Exchange and will disclose in its annual meeting proxy statement that it is a “controlled company” and the basis for that determination. The Company and Vista acknowledge and agree that, as of the Effective Date, the Company is a “controlled company.” The Company agrees to provide written notice of the preparation of a Director Election Proxy Statement to the Lead Sponsors at least 20 business days, but no more than 40 business days, prior to the earlier of the mailing and the filing date of any Director Election Proxy Statement.

3. Committees. From and after the Effective Date hereof until such time as Vista and its Affiliates cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, Vista shall have the right to designate a number of members of each committee of the Board equal to the nearest whole number greater than the product obtained by multiplying (a) the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by Vista and (b) the number of positions, including any vacancies, on the applicable committee, provided that any such designee shall be a director and shall be eligible to serve on the applicable committee under applicable law or listing standards of the Exchange, including any applicable independence requirements (subject in each case to any applicable exceptions, including those for newly public companies and for “controlled companies,” and any applicable phase-in periods). Any additional members shall be determined by the Board. Nominees designated to serve on a Board committee shall have the right to remain on such committee until the next election of directors, regardless of the level of Vista Voting Control following such designation. Unless Vista notifies the Company otherwise prior to the time the Board takes action to change the composition of a Board committee, and to the extent Vista has the requisite Vista Voting Control for Vista to nominate a Board committee member at the time the Board takes action to change the composition of any such Board committee, any Nominee currently designated by Vista to serve on a committee shall be presumed to be re-designated for such committee.

4. Amendment and Waiver. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by the Company and Vista, or in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by any party in exercising any right, power or privilege

5

hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. Vista shall not be obligated to nominate all (or any) of the Nominees it is entitled to nominate pursuant to this Agreement for any election of directors but the failure to do so shall not constitute a waiver of its rights hereunder with respect to future elections; provided, however, that in the event Vista fails to nominate all (or any) of the Nominees it is entitled to nominate pursuant to this Agreement prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), the Compensation and Nominating Committee of the Board shall be entitled to nominate individuals in lieu of such Nominees for inclusion in the Board’s Slate and the applicable Director Election Proxy Statement with respect to the election for which such failure occurred and Vista shall be deemed to have waived its rights hereunder with respect to such election. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

5. Benefit of Parties. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective permitted successors and assigns. Notwithstanding the foregoing, the Company may not assign any of its rights or obligations hereunder without the prior written consent of Vista. Except as otherwise expressly provided in Section 6, nothing herein contained shall confer or is intended to confer on any third party or entity that is not a party to this Agreement any rights under this Agreement.

6. Assignment. Upon written notice to the Company, Vista may assign to any Affiliate of Vista (other than a portfolio company) all of its rights hereunder and, following such assignment, such assignee shall be deemed to be “Vista” for all purposes hereunder.

7. Indemnification.

(a) The Company shall defend, indemnify and hold harmless Vista, its Affiliates, partners, employees, agents, directors, managers, officers and controlling Persons (collectively, the “Indemnified Parties”) from and against any and all actions, causes of action, suits, claims, liabilities, losses, damages, costs, expenses, or obligations of any kind or nature (whether accrued or fixed, absolute or contingent) in connection therewith (including reasonable attorneys’ fees and expenses) incurred by the Indemnified Parties before or after the date of this Agreement (each, an “Action”) arising directly or indirectly out of, or in any way relating to, (i) Vista’s or its Affiliates’ Beneficial Ownership of Common Stock or other equity securities of the Company or control or ability to influence the Company or any of its subsidiaries (other than any such Actions (x) to the extent such Actions arise out of any breach of this Agreement by an Indemnified Party or its Affiliates or the breach of any fiduciary or other duty or obligation of such Indemnified Party to its direct or indirect equity holders, creditors or Affiliates or (y) to the extent such Actions are directly caused by such Person’s willful misconduct), (ii) the business, operations, properties, assets or other rights or liabilities of the Company or any of its subsidiaries or (iii) any services provided prior, on or after the date of this Agreement by Vista or its Affiliates to the Company or any of its subsidiaries. The Company shall defend at its own cost and expense in respect of any Action which may be brought against the Company and/or its Affiliates and the Indemnified

6

Parties. The Company shall defend at its own cost and expense any and all Actions which may be brought in which the Indemnified Parties may be impleaded with others upon any Action by the Indemnified Parties, except that if such damage shall be proven to be the direct result of gross negligence, bad faith or willful misconduct by any of the Indemnified Parties, then such Indemnified Party shall reimburse the Company for the costs of defense and other costs incurred by the Company in proportion to such Indemnified Party’s culpability as proven. In the event of the assertion against any Indemnified Party of any Action or the commencement of any Action, the Company shall be entitled to participate in such Action and in the investigation of such Action and, after written notice from the Company to such Indemnified Party, to assume the investigation or defense of such Action with counsel of the Company’s choice at the Company’s expense; provided, however, that such counsel shall be reasonably satisfactory to the Indemnified Party. Notwithstanding anything to the contrary contained herein, the Company may retain one firm of counsel to represent all Indemnified Parties in such Action; provided, however, that the Indemnified Party shall have the right to employ a single firm of separate counsel (and any necessary local counsel) and to participate in the defense or investigation of such Action and the Company shall bear the expense of such separate counsel (and local counsel, if applicable), if (x) in the opinion of counsel to the Indemnified Party use of counsel of the Company’s choice could reasonably be expected to give rise to a conflict of interest, (y) the Company shall not have employed counsel satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of the assertion of any such Action or (z) the Company shall authorize the Indemnified Party to employ separate counsel at the Company’s expense. The Company further agrees that with respect to any Indemnified Party who is employed, retained or otherwise associated with, or appointed or nominated by, Vista or any of its Affiliates and who acts or serves as a director, officer, manager, fiduciary, employee, consultant, advisor or agent of, for or to the Company or any of its subsidiaries, that the Company or such subsidiaries, as applicable, shall be primarily liable for all indemnification, reimbursements, advancements or similar payments (the “Indemnity Obligations”) afforded to such Indemnified Party acting in such capacity or capacities on behalf or at the request of the Company, whether the Indemnity Obligations are created by law, organizational or constituent documents, contract (including this Agreement) or otherwise. The Company hereby agrees that in no event shall the Company or any of its subsidiaries have any right or claim against Vista for contribution or have rights of subrogation against Vista through an Indemnified Party for any payment made by the Company or any of its subsidiaries with respect to any Indemnity Obligation. In addition, the Company hereby agrees that in the event that Vista pay or advance an Indemnified Party any expenses with respect to an Indemnity Obligation, the Company will, or will cause its subsidiaries to, as applicable, promptly reimburse Vista, for such payment or advance upon request; subject to the receipt by the Company of a written undertaking executed by the Indemnified Party and Vista, that makes such payment or advance to repay any such amounts if it shall ultimately be determined by a court of competent jurisdiction that such Indemnified Party was not entitled to be indemnified by the Company. The foregoing right to indemnity shall be in addition to any rights that any Indemnified Party may have at common law or otherwise and shall remain in full force and effect following the completion or any termination of the engagement. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold it harmless as and to the extent contemplated by this Section 7, then the Company shall contribute to the amount paid or payable by the Indemnified Party as a result of such Action in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Indemnified Party, as the case may be, on the other hand, as well as any other relevant equitable considerations.

7

(b) The Company hereby acknowledges that the certain of the Indemnified Parties have certain rights to indemnification, advancement of expenses and/or insurance provided by investment funds managed by Vista and certain of their Affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees with respect to any indemnification, hold harmless obligation, expense advancement or reimbursement provision or any other similar obligation whether pursuant to or with respect to this Agreement, the organizational documents of the Company or any of its subsidiaries or any other agreement, as applicable, (i) that the Company and its subsidiaries are the indemnitor of first resort (i.e., their obligations to the Indemnified Parties are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for claims, expenses or obligations arising out of the same or similar facts and circumstances suffered by any Indemnified Party are secondary), (ii) that the Company shall be required to advance the full amount of expenses incurred by any Indemnified Party and shall be liable for the full amount of all expenses, liabilities, obligations, judgments, penalties, fines, and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement, the organizational documents of the Company or any of its subsidiaries or any other agreement, as applicable, without regard to any rights any Indemnified Party may have against the Fund Indemnitors, and (iii) that the Company, on behalf of itself and each of its subsidiaries, irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all Actions against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of any Indemnified Party with respect to any Action for which any Indemnified Party has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of any Indemnified Party against the Company. The Company agrees that the Fund Indemnitors are express third-party beneficiaries of the terms of this Section 7(b).

8. Headings. Headings are for ease of reference only and shall not form a part of this Agreement.

9. Governing Law. This Agreement shall be construed in accordance with and governed by the law of the State of Delaware without giving effect to the principles of conflicts of laws thereof.

Any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement may be brought against any of the parties in any federal court located in the State of Delaware or any Delaware state court, and each of the parties hereby consents to the exclusive jurisdiction of such court (and of the appropriate appellate courts) in any such suit, action or proceeding and waives any objection to venue laid therein. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each of the parties agrees that service of process upon such party at the address referred to in Section 17, together with written notice of such service to such party, shall be deemed effective service of process upon such party.

15. Further Assurances. Each of the parties hereto shall execute and deliver such further instruments and do such further acts and things as may be required to carry out the intent and purpose of this Agreement.

16. Specific Performance. Each of the parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any federal or state court located in the State of Delaware, in addition to any other remedy to which they are entitled at law or in equity.

Exhibit 10.10

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.

ARTICLE II

DEFINITIONS

As used in the Plan, the following words and phrases have the meanings specified below, unless the context clearly indicates otherwise:

2.1 “Administrator” means the Committee, or such individuals to which authority to administer the Plan has been delegated under Section 7.1 hereof.

2.2 “Affiliate” means a corporation or other entity controlled by, controlling, or under control with the Company. The term “control” (including, with correlative meaning, the terms “controlled by” and “under common control with”), as applied to any person, means the possession, directly or indirectly, of the power to direct or cause the direction of management and policies of such person, whether through the ownership of voting or other securities, by contract or otherwise.

2.3 “Agent” means the brokerage firm, bank or other financial institution, entity or person(s), if any, engaged, retained, appointed or authorized to act as the agent of the Company or an Employee with regard to the Plan.

2.4 “Board” means the Board of Directors of the Company.

2.5 “Code” means the U.S. Internal Revenue Code of 1986, as amended from time to time. Any reference to any section of the Code shall also be a reference to any successor provision and any guidance and treasury regulation promulgated thereunder.

2.6 “Committee” means the Compensation and Nominating Committee of the Board.

2.7 “Common Stock” means the common stock, USD 0.01 par value per share, of the Company.

2.8 “Company” means Integral Ad Science Holding Corp., a Delaware corporation, and its successors by operation of law.

2.9 “Compensation” of an Employee means the regular straight-time earnings or base salary, commissions and payments received for overtime and shift premiums received by such Employee as compensation for services to the Company or any Designated Company, determined before giving effect to any salary reduction agreement pursuant to (a) a qualified cash or deferred arrangement (within the meaning of Section 401(k) of the Code), or (b) a cafeteria plan (within the meaning of Section 125 of the Code). Compensation shall exclude any annual incentive compensation or other payments made under any bonus program, vacation pay, holiday pay, jury duty pay, funeral leave pay, military leave pay, education or tuition reimbursements, travel expenses, business and moving reimbursements, imputed income arising under any group insurance or benefit program, income received in connection with any share options, share appreciation rights, restricted shares, restricted share units or other compensatory equity awards, fringe benefits, other special or one-time payments (e.g., retention or sign-on bonuses) and all contributions made by the Company or any Designated Subsidiary for the Employee’s benefit under any employee benefit plan now or hereafter established. The Administrator, in its discretion, may establish a different definition of Compensation for an Offering, which for the Section 423 Component shall apply on a uniform and nondiscriminatory 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 discretion as eligible to participate in the Plan, in accordance with Section 7.2 hereof, such designation to specify whether such participation is in the Section 423 Component 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 participating in the Non-Section 423 Component, the Administrator may exclude such Affiliate or Subsidiary from participating in the Plan, notwithstanding that the Designated Company in respect of which such Affiliate or Subsidiary is disregarded may participate in the Plan.

2.11 “Effective Date” means the date the Plan is adopted by the Board, subject to approval of the Company’s shareholders.

2.12 “Eligible Employee” means any Employee of the Company or a Designated Company who has completed at least six (6) months of continuous service with the Company. The Administrator, in its discretion, may also exclude any or all of the following unless prohibited by applicable law, Employees:

(a) who are customarily scheduled to work 20 hours or less per week;

(b) whose customary employment is not more than five months in a calendar year;

(c) who are not employed by the Company or a Designated Company prior to the applicable Enrollment Date occurs; and

(d) any Employee who is a “highly compensated employee” of the Company or any Designated Company (within the meaning of Section 414(q) of the Code), or that is such a “highly compensated employee” (A) with compensation above a specified level, (B) who is an officer or (C) who is subject to the disclosure requirements of Section 16(a) of the Exchange Act; or

(e) any Employee who is a citizen or resident of a jurisdiction outside the United States (without regard to whether they are also a citizen of the United States or a resident alien (within the meaning of Section 7701(b)(1)(A) of the Code)) if either (A) the grant of the Option is prohibited under the laws of the jurisdiction governing such Employee, or (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 does not render services to the Company or a Designated Company in the status of an employee within the meaning of Section 3401(c) of the Code. For purposes of the Plan, the employment relationship shall be treated as continuing intact while 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. § 1.421-1(h)(2).

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

(a) If the Common Stock is (i) listed on any established securities exchange (such as the New York Stock Exchange or Nasdaq Stock Market), (ii) listed on any national market system or (iii) listed, quoted or traded on any automated quotation system, the Fair Market Value of a Share shall be the closing sales price for a Share as quoted on such exchange or system for such date or, if there is no closing sales price for a Share on the date in question, the closing sales price for a Share on the last preceding date for which such quotation exists, as reported in The Wall Street Journal or such other source as the Administrator deems reliable;

(b) If the Common Stock is not listed on an established securities exchange, national market system or automated quotation system, but the Common Stock is regularly quoted by a recognized securities dealer, the Fair Market Value of a Share shall be the mean of the high bid and low asked prices for such date or, if there are no high bid and 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 deems reliable; or

(c) If the Common Stock is neither listed on an established securities exchange, national market system or automated quotation system nor regularly quoted by a recognized securities dealer, the Fair Market Value of a Share shall be established by the Administrator in good faith.

2.21 “Offering” means an offer under the Plan of an Option that may be exercised during an Offering Period as further described in Article 4 hereof.

To the extent permitted by Treas. Reg. § 1.423-2(a)(1), the terms of each separate Offering under 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 (a)(3).

2.22 “Offering Period” means the periods of approximately twenty-four (24) months during which Options shall be granted to Participants, commencing on such Trading Day as designated by the Administrator and terminating on a Trading Day approximately twenty-four (24) months later, each as determined by the Administrator in its sole discretion.

ARTICLE III

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 or the fixed dollar amount 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.

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) [•] 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 [•] 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.
