2. Agreements to Sell and Purchase. The Company hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the terms and conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Company the respective numbers of Firm Shares set forth in Schedule II hereto opposite its name at $16.74 a share (the “Purchase Price”).

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to 2,250,000 Additional Shares at the Purchase Price, provided, however, that the amount paid by the Underwriters for any Additional Shares shall be reduced by an amount per share equal to any dividends declared by the Company and payable on the Firm Shares but not payable on such Additional Shares. The Representatives may exercise this right on behalf of the Underwriters in whole or from time to time in part by giving written notice not later than 30 days after the date of this Agreement. Any exercise notice shall specify the number of Additional Shares to be purchased by the Underwriters and the date on which such shares are to be purchased. Each purchase date must be at least one business day after the written notice is given and may not be earlier than the closing date for the Firm Shares or later than ten business

days after the date of such notice. Additional Shares may be purchased as provided in Section 4 hereof solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. On each day, if any, that Additional Shares are to be purchased (an “Option Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as the Representatives may determine) that bears the same proportion to the total number of Additional Shares to be purchased on such Option Closing Date as the number of Firm Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

3. Terms of Public Offering. The Company is advised by the Representatives that the Underwriters propose to make a public offering of their respective portions of the Shares as soon after the Registration Statement and this Agreement have become effective as in the Representatives’ judgment is advisable. The Company is further advised by the Representatives that the Shares are to be offered to the public initially at $18.00 a share (the “Public Offering Price”) and to certain dealers selected by the Representatives at a price that represents a concession not in excess of $0.756 a share under the Public Offering Price.

4. Payment and Delivery. Payment for the Firm Shares shall be made to the Company in Federal or other funds immediately available in New York City against delivery of such Firm Shares for the respective accounts of the several Underwriters at 10:00 a.m., New York City time, on July 2, 2021, or at such other time on the same or such other date, not later than July 12, 2021, as shall be designated in writing by Morgan Stanley. The time and date of such payment are hereinafter referred to as the “Closing Date.”

Payment for any Additional Shares shall be made to the Company in Federal or other funds immediately available in New York City against delivery of such Additional Shares for the respective accounts of the several Underwriters at 10:00 a.m., New York City time, on the date specified in the corresponding notice described in Section 2 or at such other time on the same or on such other date, in any event not later than August 12, 2021, as shall be designated in writing by the Representatives.

The Firm Shares and Additional Shares shall be registered in such names and in such denominations as the Representatives shall request not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be. The Firm Shares and Additional Shares shall be delivered to the Representatives on the Closing Date or an Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the transfer of the Shares to the Underwriters duly paid, against payment of the Purchase Price therefor.

5. Conditions to the Underwriters’ Obligations.

(iii) there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Time of Sale Prospectus that, in the Representatives’ judgment, is material and adverse and that makes it, in the Representatives’ judgment, impracticable to market the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus.

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.

(a) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company 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 third paragraph, the information regarding sales to discretionary accounts in the seventh paragraph, the information regarding stabilization and short positions in the twelfth paragraph and the information regarding internet distributions in the fourteenth paragraph (the “Underwriter Information”).

(b) 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 9(a), 9(b) or 9(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 and (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. 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. 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.

(c) To the extent the indemnification provided for in Section 9(a), 9(b) or (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 9(c)(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 9(c)(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 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 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 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 Company 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.

(d) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 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 9(c). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(c) 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 9, 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 9 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.

(e) The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company 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, 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.

10. 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.

11. 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 11 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 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. In any such case either the Representatives or the Company 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 to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company 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.

12. 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 Underwriters 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 acknowledges 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 or any other person, (ii)the Underwriters owe the Company 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 (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 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.

13. 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.

14. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 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.

15. 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.

16. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

17. Notices.

Ladies and Gentlemen:

The undersigned understands that Morgan Stanley & Co. LLC, Jefferies LLC, Barclays Capital Inc. and Evercore Group L.L.C. (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 15,000,000 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

A-1

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 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

A-2

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 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

A-3

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 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

A-4

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.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering.

(a) 50,000,000 shares of Preferred Stock, par value $0.001 per share (the“Preferred Stock”); and

The Preferred Stock and the Common Stock shall have the designations, rights, powers and preferences and the qualifications, restrictions and limitations thereof, if any, set forth below.

Section 2. Preferred Stock. The Board of Directors of the Corporation (the “Board of Directors”) is authorized, subject to limitations prescribed by law, to provide, by resolution or resolutions, for the issuance of shares of Preferred Stock in one or more series, and with respect to each series, to establish the number of shares to be included in each such series,

and to fix the voting powers (if any), designations, powers, preferences, and relative, participating, optional or other special rights, if any, of the shares of each such series, and any qualifications, limitations or restrictions thereof. The powers (including voting powers), preferences, and relative, participating, optional and other special rights of each series of Preferred Stock and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding. Subject to the rights of the holders of any series of Preferred Stock, the number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the approval of the Board of Directors and by the affirmative vote of the holders of a majority in voting power of the outstanding shares of capital stock of the Corporation entitled to vote generally in an election of directors, without the separate vote of the holders of the Preferred Stock as a class, irrespective of the provisions of Section 242(b)(2) of the DGCL.

Section 3. Common Stock.

(a) Except as otherwise provided by the DGCL or this certificate of incorporation (as it may be amended, the “Certificate”) and subject to the rights of holders of any series of Preferred Stock then outstanding, all of the voting power of the stockholders of the Corporation shall be vested in the holders of the Common Stock. Each share of Common Stock shall entitle the holder thereof to one vote for each share held by such holder on all matters voted upon by the stockholders of the Corporation; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate (including any certificate of designation relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Certificate (including any certificate of designation relating to any series of Preferred Stock) or pursuant to the DGCL.

(b) Except as otherwise required by law or expressly provided in this Certificate, each share of Common Stock shall have the same powers, rights and privileges and shall rank equally, share ratably and be identical in all respects as to all matters.

(c) Subject to the rights of the holders of any series of Preferred Stock then outstanding and to the other provisions of applicable law and this Certificate, holders of Common Stock shall be entitled to receive equally, on a per share basis, such dividends and other distributions in cash, securities or other property of the Corporation if, as and when declared thereon by the Board of Directors from time to time out of assets or funds of the Corporation legally available therefor.

(d) In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, after payment or provision for payment of the Corporation’s debts and any other payments required by law and amounts payable upon outstanding shares of Preferred Stock ranking senior to the shares of Common Stock upon such dissolution, liquidation or winding up, if any, the remaining assets of the Corporation shall be distributed to the holders of shares of Common Stock

2

and the holders of shares of any other class or series ranking equally with the shares of Common Stock upon such dissolution, liquidation or winding up, equally on a per share basis. Subject to the rights of the holders of Preferred Stock then outstanding and the other provisions of this Certificate, a merger or consolidation of the Corporation with or into any other corporation or other entity, or a sale or conveyance of all or any part of the assets of the Corporation (which shall not in fact result in the liquidation of the Corporation and the distribution of assets to its stockholders) shall not be deemed to be a voluntary or involuntary liquidation or dissolution or winding up of the Corporation within the meaning of this Paragraph (d).

ARTICLE SIX

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. The term of office of the initial Class I directors shall expire at the first annual meeting of stockholders following the date the Common Stock is first publicly traded (the “IPO Date”), the term of office of the initial Class II directors shall expire at the second succeeding annual meeting of stockholders after the IPO Date and the term of office of the initial Class III directors shall expire at the third succeeding annual meeting of the stockholders after the IPO Date. For the purposes hereof, the Board of Directors may assign directors already in office to Class I, Class II and Class III, in accordance with the terms of that certain Director Nomination Agreement, dated on or about June 29, 2021 (as amended and/or restated or supplemented in accordance with its terms, the “Nomination Agreement”), by and among the Corporation and the investors named therein. 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

4

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.

Section 8. Advance Notice. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws.

ARTICLE SEVEN

Section 1. Limitation of Liability.

(a) To the fullest extent permitted by the DGCL as it now exists or may hereafter be amended no director of the Corporation shall be liable to the Corporation or its stockholders for monetary damages arising from a breach of fiduciary duty as a director.

(b) Any amendment, repeal or modification of the foregoing paragraph shall not adversely affect any right or protection of a director of the Corporation existing at the time of such amendment, repeal or modification with respect to any act, omission or other matter occurring prior to such amendment, repeal or modification.

ARTICLE EIGHT

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

5

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 NINE

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 Nine 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

6

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 Nine, 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 Nine; provided however, that, to the fullest extent permitted by law, neither the alteration, amendment or repeal of this Article Nine nor the adoption of any provision of this Certificate inconsistent with this Article Nine 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 Nine

ARTICLE TEN

Section 1. Section 203 of the DGCL. The Corporation expressly elects not to be subject to the provisions of Section 203 of the DGCL.

Section 2. Business Combinations with Interested Stockholders. Notwithstanding any other provision in this Certificate to the contrary, the Corporation shall not engage in any Business Combination (as defined hereinafter), at any point in time at which the Common Stock is registered under Section 12(b) or 12(g) of the Exchange Act of 1934, as amended (the “Exchange Act”), with any Interested Stockholder (as defined hereinafter) for a period of three years following the time that such stockholder became an Interested Stockholder, unless:

(c) at or subsequent to such time, the Business Combination is approved by the Board of Directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least sixty-six and two-thirds percent (66²⁄₃%) of the outstanding Voting Stock which is not owned by such Interested Stockholder.

Section 3. Exceptions to Prohibition on Interested Stockholder Transactions. The restrictions contained in this Article Ten 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

(b) the Business Combination is proposed prior to the consummation or abandonment of and subsequent to the earlier of the public announcement or the notice required hereunder of a proposed transaction which (i) constitutes one of the transactions described in the second sentence of this Section 3(b) of Article Ten; (ii) is with or by a Person who either was not an Interested Stockholder during the previous three years or who became an Interested Stockholder with the approval of the Board of Directors; and (iii) is approved or not opposed by a majority of the directors then in office (but not less than one) who were directors prior to any Person becoming an Interested Stockholder during the previous three years or were recommended for election or elected to succeed such directors by a majority of such directors. The proposed transactions referred to in the preceding sentence are limited to (x) a merger or consolidation of the Corporation (except for a merger in respect of which, pursuant to Section 251(f) of the DGCL, no vote of the stockholders of the Corporation is required); (y) a sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions),

The Corporation shall give not less than 20 days’ notice to all Interested Stockholders prior to the consummation of any of the transactions described in clause (x) or (y) of the second sentence of this Section 3(b) of Article Ten.

Section 4. Definitions. As used in this Article Ten only, and unless otherwise provided by the express terms of this Article Ten the following terms shall have the meanings ascribed to them as set forth in this Section 4 and, to the extent such terms are defined elsewhere in this Certificate, such definitions shall not apply to this Article Ten:

(c) “Business Combination” means:

(i) any merger or consolidation of the Corporation or any direct or indirect majority-owned subsidiary of the Corporation with (A) the Interested Stockholder, or (B) any other corporation, partnership, unincorporated association or entity if the merger or consolidation is caused by the Interested Stockholder and as a result of such merger or consolidation Section 2 of this Article Ten is not applicable to the surviving entity;

ARTICLE I

OFFICES

Section 1. Offices. Integral Ad Science Holding Corp. (the “Corporation”) may have an office or offices other than its registered office at such place or places, either within or outside the State of Delaware, as the Board of Directors of the Corporation (the “Board of Directors”) may from time to time determine or the business of the Corporation may require. The registered office of the Corporation in the State of Delaware shall be as stated in the Corporation’s certificate of incorporation as then in effect (the “Certificate of Incorporation”).

ARTICLE II

MEETINGS OF STOCKHOLDERS

Section 1. Place of Meetings. The Board of Directors may designate a place, if any, either within or outside the State of Delaware, as the place of meeting for any annual meeting or for any special meeting of stockholders.

Section 2. Annual Meeting. An annual meeting of the stockholders shall be held at such date and time as is specified by resolution of the Board of Directors. At the annual meeting, stockholders shall elect directors to succeed those whose terms expire at such annual meeting and transact such other business as properly may be brought before the annual meeting pursuant to Section 11 of this ARTICLE II of these Bylaws (these “Bylaws”). The Board of Directors may postpone, reschedule or cancel any annual meeting of stockholders previously scheduled by the Board of Directors.

Section 3. Special Meetings. Special meetings of the stockholders may only be called in the manner provided in the Certificate of Incorporation. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice. The Board of Directors may postpone, reschedule or cancel any special meeting of stockholders previously scheduled by the Board of Directors; provided that prior to the Stockholder Consent Trigger Date (as defined in the Certificate of Incorporation) any special meeting called at the request of Principal Stockholder (as defined herein) may not be postponed, rescheduled or canceled without the consent of the Principal Stockholder at whose request the meeting was originally called.

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. Notice to stockholders may also be given by other forms of electronic transmission consented to by the stockholder. If given by facsimile telecommunication, such notice shall be deemed given when directed to a number at which the stockholder has consented to receive notice by facsimile. If given by a posting on an electronic network together with separate notice to the stockholder of such specific posting, such notice shall be deemed given upon the later of (x) such posting and (y) the giving of such separate notice. If notice is given by any other form of electronic transmission, such notice shall be deemed given when directed to the stockholder. An affidavit of the secretary or an assistant secretary of the Corporation, the transfer agent of the Corporation or any other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(b) Waiver of Notice. Whenever notice is required to be given under any provisions of the DGCL, the Certificate of Incorporation or these Bylaws, a written waiver thereof, signed by the stockholder entitled to notice, or a waiver by electronic transmission given by the stockholder entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. 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

2

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.

3

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.

13

behalf the nomination or proposal is made or solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies or votes in support of such stockholder’s nominee or proposal in compliance with such stockholder’s representation as required by Section 11(a)(iii)(G) or Section 11(b)(iii)(G), as applicable, of these Bylaws) and, if any nomination or other business is not made or brought in compliance with these Bylaws, to declare that such nomination or proposal of other business be disregarded and not acted upon. Notwithstanding the foregoing provisions of this Section 11, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the Corporation to present a nomination or proposed business, such nomination shall be disregarded and such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Section 11, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

(i) Compliance with Exchange Act. 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.

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 June 29, 2021 (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

14

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 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.

15

(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 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

16

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. 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.

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

19

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.

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

23

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 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. The Corporation shall not be bound to recognize any equitable or other claim to or interest in such share or shares of stock on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise required by applicable law.

24

Section 4. Fixing a Record Date for Purposes Other Than Stockholder Meetings or Actions by Written Consent. In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purposes of any other lawful action (other than stockholder meetings and stockholder consents which are expressly governed by Sections 12 and 13 of ARTICLE II hereof), 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, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

ARTICLE VI

GENERAL PROVISIONS

Section 1. Dividends. Subject to and in accordance with applicable law, the Certificate of Incorporation and any certificate of designation relating to any series of preferred stock, dividends upon the shares of capital stock of the Corporation may be declared and paid by the Board of Directors, in accordance with applicable law.

Section 6. Voting Securities Owned By Corporation. Voting securities in any other corporation or entity held by the Corporation shall be voted by the Chair of the Board, Chief Executive Officer, the President or the Chief Financial Officer, unless the Board of Directors specifically confers authority to vote with respect thereto, which authority may be general or confined to specific instances, upon some other person or officer. Any person authorized to vote securities shall have the power to appoint proxies, with general power of substitution.

Section 8. Section Headings. Section headings in these Bylaws are for convenience of reference only and shall not be given any substantive effect in limiting or otherwise construing any provision herein.

Section 9. Inconsistent Provisions. In the event that any provision (or part thereof) of these Bylaws is or becomes inconsistent with any provision of the Certificate of Incorporation, the DGCL, any other applicable law or the Nomination Agreement, the provision (or part thereof) of these Bylaws shall be construed to be consistent with such other provision or provisions, and to the extent such provision may not be so construed, such provision shall be deemed amended to incorporate such other provision so as to eliminate any such inconsistency and as so amended shall be given full force and effect.

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)

26

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 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

27

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.

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.

28

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.

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.

(a) Requests for Registration. At any time and from time to time, the Sponsor Investors may request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-1 or any similar long-form registration statement (“Long-Form Registrations”) or on Form S-3 or any similar short-form registration statement (“Short-Form Registrations”), if available (any such requested registration, a “Demand Registration”). The Sponsor Investors may request that any Demand Registration be made pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) and (if the Company is a WKSI at the time any such request is submitted to the Company or will become one by the time of the filing of such Shelf Registration) that such Shelf Registration be an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “Automatic Shelf Registration Statement”). Each request for a Demand Registration must specify the approximate number or dollar value of Registrable Securities requested to be registered by the requesting Holders and (if known) the intended method of distribution. The Sponsor Investors will be entitled to request an unlimited number of Demand Registrations. The Company will pay all Registration Expenses, whether or not any such registration is consummated.

(b) Notice to Other Investors. Within four (4) Business Days after receipt of any such request, the Company will give written notice of the Demand Registration to all other Holders and, subject to the terms of Section 1(e), will include in such Demand Registration (and in all related registrations and qualifications under state blue sky laws and in any related underwriting) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten (10) days after the receipt of the Company’s notice; provided that, with the written consent of the Sponsor Investor, the Company may, or at the written request of the Sponsor Investors, the Company shall, instead provide notice of the Demand Registration to all Other Investors within three (3) Business Days following the non-confidential filing of the registration statement with respect to the Demand Registration so long as such registration statement is not an Automatic Shelf Registration Statement.

(c) Form of Registrations. All Long-Form Registrations will be underwritten registrations unless otherwise approved by the Sponsor Investor. Demand Registrations will be Short-Form Registrations whenever the Company is permitted to use any applicable short form unless otherwise requested by the Sponsor Investor.

(d) Shelf Registrations.

(i) For so long as a registration statement for a Shelf Registration (a “Shelf Registration Statement”) is and remains effective, the Sponsor Investors will have the right at any time or from time to time to elect to sell pursuant to an offering (including an underwritten offering Registrable Securities available for sale pursuant to such registration statement (“Shelf Registrable Securities”). If the Sponsor Investors desire to sell Registrable Securities pursuant to an underwritten offering, then the Sponsor Investors may deliver to the Company a written notice (a “Shelf Offering Notice”) specifying the number of Shelf Registrable Securities that the Sponsor Investors desire to sell pursuant to such underwritten offering (the “Shelf Offering”). As promptly as practicable, but in no event later than two (2) Business Days after receipt of a Shelf Offering Notice, the Company will give written notice of such Shelf Offering Notice to all other Holders of Shelf Registrable Securities that have been identified as selling stockholders in such Shelf Registration Statement and are otherwise permitted to sell in such Shelf Offering, which such notice shall request that each such Holder specify, within seven (7) days after the Company’s receipt of the Shelf Offering Notice, the maximum number of Shelf Registrable Securities such Holder desires to be disposed of in such Shelf Offering. The Company, subject to Section 1(e) and Section 7, will include in such Shelf Offering all Shelf Registrable Securities with respect to which the Company has received timely written requests for inclusion. The Company will, as expeditiously as possible (and in any event within fourteen (14) days after the receipt of a Shelf Offering Notice), but subject to Section 1(e), use its best efforts to consummate such Shelf Offering.

(ii) If the Sponsor Investors desire to engage in an underwritten block trade or bought deal pursuant to a Shelf Registration Statement (either through filing an Automatic Shelf Registration Statement or through a take-down from an already existing Shelf Registration Statement) (each, an “Underwritten Block Trade”), then notwithstanding the time periods set forth in Section 1(d)(i), the Sponsor Investors may notify the Company of the Underwritten Block Trade not less than two (2) Business Days prior to the day such offering is first anticipated to commence. If requested by the Sponsor Investors, the Company will promptly notify other Holders of such Underwritten Block Trade and such notified Holders (each, a “Potential Participant”) may elect whether or not to participate no later than the next Business Day (i.e. one (1) Business Day prior to the day such offering is to commence) (unless a longer period is agreed to by the Sponsor Investors), and the Company will as expeditiously as possible use its best efforts to facilitate such Underwritten Block Trade (which may close as early as two (2) Business Days after the date it commences); provided further that, notwithstanding the provisions of Section 1(d)(i), no Holder (other than Holders of Sponsor Investor Registrable Securities) will be permitted to participate in an Underwritten Block Trade without the written consent of the Sponsor Investor. Any Potential Participant’s request to participate in an Underwritten Block Trade shall be binding on the Potential Participant.

(iii) All determinations as to whether to complete any Shelf Offering and as to the timing, manner, price and other terms of any Shelf Offering contemplated by this Section 1(d) shall be determined by the Sponsor Investors, and the Company shall use its best efforts to cause any Shelf Offering to occur in accordance with such determinations as promptly as practicable.

(iv) The Company will, at the request of the Sponsor Investors, file any prospectus supplement or any post-effective amendments and otherwise take any action necessary to include therein all disclosure and language deemed necessary or advisable by the Sponsor Investors to effect such Shelf Offering.

(e) Priority on Demand Registrations and Shelf Offerings. The Company will not include in any Demand Registration any securities which are not Registrable Securities without the prior written consent of the Sponsor Investors. If a Demand Registration or a Shelf Offering is an underwritten offering

-2-

and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and (if permitted hereunder) other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities (if any), which can be sold therein without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, then the Company will include in such offering (prior to the inclusion of any securities which are not Registrable Securities) the number of Registrable Securities requested to be included by any Holders which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among such Holders on the basis of the number of Registrable Securities owned by each such Holder. Notwithstanding anything to the contrary herein, if any Holders of Executive Registrable Securities have requested to include such securities in an underwritten offering and the managing underwriters for such offering advise the Company that in their opinion the inclusion of some or all of such Executive Registrable Securities could adversely affect the marketability, proposed offering price, timing and/or method of distribution of the offering, then the Company shall exclude from such offering the number of such Executive Registrable Securities identified by the managing underwriters as having any such adverse effect prior to the exclusion of any Registrable Securities of any other Holders as set forth in this Section 1(e), which, for the avoidance of doubt, may be all such Executive Registrable Securities requested to be included such offering.

(f) Restrictions on Demand Registration and Shelf Offerings.

(i) The Company may postpone, for up to 60 days (or with the consent of the Sponsor Investors, a longer period) from the date of the request (the “Suspension Period”), the filing or the effectiveness of a registration statement for a Demand Registration or suspend the use of a prospectus that is part of a Shelf Registration Statement (and therefore suspend sales of the Shelf Registrable Securities) by providing written notice to the Holders if the following conditions are met: (A) the Company determines that the offer or sale of Registrable Securities would reasonably be expected to have a material adverse effect on any proposal or plan by the Company or any Subsidiary to engage in any material acquisition of assets or stock (other than in the ordinary course of business) or any material merger, consolidation, tender offer, recapitalization, reorganization, financing or other transaction involving the Company and (B) upon advice of counsel, the sale of Registrable Securities pursuant to the registration statement would require disclosure of material non-public information not otherwise required to be disclosed under applicable law, and either (x) the Company has a bona fide business purpose for preserving the confidentiality of such transaction, (y) disclosure would have a material adverse effect on the Company or the Company’s ability to consummate such transaction, or (z) such transaction renders the Company unable to comply with SEC requirements, in each case under circumstances that would make it impractical or inadvisable to cause the registration statement (or such filings) to become effective or to promptly amend or supplement the registration statement on a post effective basis, as applicable. The Company may delay or suspend the effectiveness of a Demand Registration or Shelf Registration Statement pursuant to this Section 1(f)(i) only once in any twelve (12)-month period (for avoidance of doubt, in addition to the Company’s rights and obligations under Section 4(a)(vi)) unless additional delays or suspensions are approved by the Sponsor Investors.

(ii) In the case of an event that causes the Company to suspend the use of a Shelf Registration Statement as set forth in Section 1(f)(i) above or pursuant to Section 4(a)(vi) (a “Suspension Event”), the Company will give a notice to the Holders whose Registrable Securities are registered pursuant to such Shelf Registration Statement (a “Suspension Notice”) to suspend sales of the Registrable Securities and such notice must state generally the basis for the notice and that such suspension will continue only for so long as the Suspension Event or its effect is continuing. Each Holder agrees not to effect any sales of its Registrable Securities pursuant to such

-3-

Shelf Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company and prior to receipt of an End of Suspension Notice. A Holder may recommence effecting sales of the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following further written notice to such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice will be given by the Company to the Holders promptly following the conclusion of any Suspension Event (and in any event during the permitted Suspension Period).

(g) Selection of Underwriters. The legal counsel to the Company, the investment banker(s) and manager(s) to administer any underwritten offering in connection with any Demand Registration or Shelf Offering shall be selected by the Sponsor Investors.

(h) Other Registration Rights. Except as provided in this Agreement, the Company will not grant to any Person(s) the right to request the Company or any Subsidiary to register any equity securities of the Company or any Subsidiary, or any securities convertible or exchangeable into or exercisable for such securities, without the prior written consent of the Sponsor Investors; provided that, with the prior approval of the Sponsor Investors, the Company may grant rights to employees of the Company and its Subsidiaries to participate in Piggyback Registrations so long as they sign a Joinder as an “Executive” and Holder of “Executive Registrable Securities” hereunder.

(i) Revocation of Demand Notice or Shelf Offering Notice. At any time prior to the effective date of the registration statement relating to a Demand Registration or the “pricing” of any offering relating to a Shelf Offering Notice, the Sponsor Investors who initiated such Demand Registration or Shelf Offering may revoke or withdraw such notice of a Demand Registration or Shelf Offering Notice on behalf of all Holders participating in such Demand Registration or Shelf Offering without liability to such Holders (including, for the avoidance of doubt, the other Participating Sponsor Investors), in each case by providing written notice to the Company.

(j) Confidentiality. Each Holder agrees to treat as confidential the receipt of any notice hereunder (including notice of a Demand Registration, a Shelf Offering Notice and a Suspension Notice) and the information contained therein, and not to disclose or use the information contained in any such notice (or the existence thereof) without the prior written consent of the Company until such time as the information contained therein is or becomes available to the public generally (other than as a result of disclosure by such Holder in breach of the terms of this Agreement).

Section 2 Piggyback Registrations.

(a) Right to Piggyback. Whenever the Company proposes to register any of its equity securities under the Securities Act (including primary and secondary registrations, and other than pursuant to an Excluded Registration) (a “Piggyback Registration”), the Company will give prompt written notice (and in any event within three (3) Business Days after the public filing of the registration statement relating to the Piggyback Registration) to all Holders of its intention to effect such Piggyback Registration and, subject to the terms of Section 2(b) and Section 2(c), will include in such Piggyback Registration (and in all related registrations or qualifications under blue sky laws and in any related underwriting) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten (10) days after delivery of the Company’s notice. Any Participating Sponsor Investor may withdraw its request for inclusion at any time prior to executing the underwriting agreement, or if none, prior to the applicable registration statement becoming effective.

-4-

(b) Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company will include in such registration (i) first, the securities the Company proposes to sell, (ii) second, any Registrable Securities requested to be included in such registration by any Holder which, in the opinion of the underwriters, can be sold without any such adverse effect, pro rata among such Holders on the basis of the number of Registrable Securities owned by each such Holder, and (iii) third, other securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect. Notwithstanding anything to the contrary herein, if any Holders of Executive Registrable Securities have requested to include such securities in a Piggyback Registration that is an underwritten primary offering on behalf of the Company and the managing underwriters for such offering advise the Company in writing that in their opinion the inclusion of some or all of such Executive Registrable Securities could adversely affect the marketability, proposed offering price, timing and/or method of distribution of the offering, the Company shall first exclude from such offering the number (which may be all) of such Executive Registrable Securities identified by the managing underwriters as having any such adverse effect prior to the exclusion of any securities in such offering.

(c) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company’s equity securities (other than pursuant to Section 1 hereof), and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company will include in such registration (i) first, the securities requested to be included therein by the holders initially requesting such registration which, in the opinion of the underwriters, can be sold without any such adverse effect, (ii) second, any Registrable Securities requested to be included in such registration by any Holder, pro rata among such Holders on the basis of the number of Registrable Securities owned by each such Holder which, in the opinion of the underwriters, can be sold without any such adverse effect, and (iv) third, other securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect. Notwithstanding anything to the contrary herein, if any Holders of Executive Registrable Securities have requested to include such securities in a Piggyback Registration that is an underwritten secondary offering and the managing underwriters for such offering advise the Company in writing that in their opinion the inclusion of some or all of such Executive Registrable Securities could adversely affect the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall be permitted to first exclude from such offering the number (which may be all) of such Executive Registrable Securities identified by the managing underwriters as having any such adverse effect prior to the exclusion of any securities in such offering.

(d) Right to Terminate Registration. The Company will have the right to terminate or withdraw any registration initiated by it under this Section 2, whether or not any holder of Registrable Securities has elected to include securities in such registration.

(e) Selection of Underwriters. If any Piggyback Registration is an underwritten offering, the legal counsel for the Company, the investment banker(s) and manager(s) for the offering shall be selected by the Sponsor Investors.

Section 3 Stockholder Lock-Up Agreements and Company Holdback Agreement.

-5-

(a) Stockholder Lock-up Agreements. In connection with any underwritten Public Offering, each Holder will enter into any lock-up, holdback or similar agreements requested by the underwriter(s) managing such offering, in each case with such modifications and exceptions as may be approved by the Sponsor Investors. Without limiting the generality of the foregoing, each Holder hereby agrees that in connection with the initial Public Offering and in connection with any Demand Registration, Shelf Offering or Piggyback Registration that is an underwritten Public Offering, not to (i) offer, sell, contract to sell, pledge or otherwise dispose of (including sales pursuant to Rule 144), directly or indirectly, any equity securities of the Company (including equity securities of the Company that may be deemed to be beneficially owned by such Holder in accordance with the rules and regulations of the SEC) (collectively, “Securities”), or any securities, options or rights convertible into or exchangeable or exercisable for Securities (collectively, “Other Securities”), (ii) enter into a transaction which would have the same effect as described in clause (i) above, (iii) enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences or ownership of any Securities or Other Securities, whether such transaction is to be settled by delivery of such Securities or Other Securities, in cash or otherwise (each of (i), (ii) and (iii) above, a “Sale Transaction”), or (iv) publicly disclose the intention to enter into any Sale Transaction, commencing on the date on which the Company gives notice to the Holders that a preliminary prospectus has been circulated for such underwritten Public Offering or the “pricing” of such offering and continuing to the date that is (x) 180 days following the date of the final prospectus for such underwritten Public Offering in the case of the initial Public Offering or (y) 90 days following the date of the final prospectus in the case of any other such underwritten Public Offering (each such period, or such shorter period as agreed to by the managing underwriters, a “Holdback Period”), in each case with such modifications and exceptions as may be approved by the Sponsor Investors. The Company may impose stop-transfer instructions with respect to any Securities or Other Securities subject to the restrictions set forth in this Section 3(a) until the end of such Holdback Period.

(b) Company Holdback Agreement. The Company (i) will not file any registration statement for a Public Offering or cause any such registration statement to become effective, or effect any public sale or distribution of its Securities or Other Securities during any Holdback Period (other than as part of such underwritten Public Offering, or a registration on Form S-4 or Form S-8 or any successor or similar form which is (x) then in effect or (y) shall become effective upon the conversion, exchange or exercise of any then outstanding Other Securities) and (ii) will cause each holder of Securities and Other Securities (including each of its directors and executive officers) to agree not to effect any Sale Transaction during any Holdback Period, except as part of such underwritten registration (if otherwise permitted), unless approved in writing by the Sponsor Investors and the underwriters managing the Public Offering and to enter into any lock-up, holdback or similar agreements requested by the underwriter(s) managing such offering, in each case with such modifications and exceptions as may be approved by the Sponsor Investors.

Section 4 Registration Procedures.

(v) use its best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company will not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph or (B) consent to general service of process in any such jurisdiction or (C) subject itself to taxation in any such jurisdiction);

-7-

prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, subject to Section 1(f), if required by applicable law or to the extent requested by the Sponsor Investor, the Company will use its best efforts to promptly prepare and file a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading and (D) if at any time the representations and warranties of the Company in any underwriting agreement, securities sale agreement, or other similar agreement, relating to the offering shall cease to be true and correct;

(vii) (A) use best efforts to cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed and, if not so listed, to be listed on a securities exchange and, without limiting the generality of the foregoing, to arrange for at least two market markers to register as such with respect to such Registrable Securities with FINRA, and (B) comply (and continue to comply) with the requirements of any self-regulatory organization applicable to the Company, including without limitation all corporate governance requirements;

(viii) use best efforts to provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration statement;

-9-

(xxi) use its best efforts to provide (A) a legal opinion of the Company’s outside counsel, dated the effective date of such registration statement addressed to the Company, (B) on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a Demand Registration or Shelf Offering, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the closing date of the applicable sale, (1) one or more legal opinions of the Company’s outside counsel, dated such date, in form and substance as customarily given to underwriters in an underwritten public offering or, in the case of a non-underwritten offering, to the broker, placement agent or other agent of the Holders assisting in the sale of the Registrable Securities and (2) one or more “negative assurances letters” of the Company’s outside counsel, dated such date, in form and substance as is customarily given to underwriters in an underwritten public offering or, in the case of a non-underwritten offering, to the broker, placement agent or other agent of the Holders assisting in the sale of the Registrable Securities, in each case, addressed to the underwriters, if any, or, if requested, in the case of a non-underwritten offering, to the broker, placement agent or other agent of the Holders assisting in the sale of the Registrable Securities and (3) customary certificates executed by authorized officers of the Company as may be requested by any Holder or any underwriter of such Registrable Securities;

-10-

(c) Automatic Shelf Registration Statements. If the Company files any Automatic Shelf Registration Statement for the benefit of the holders of any of its securities other than the Holders, and the Sponsor Investors do not request that their Registrable Securities be included in such Shelf Registration Statement, the Company agrees that, at the request of the Sponsor Investors, it will include in such Automatic Shelf Registration Statement such disclosures as may be required by Rule 430B in order to ensure that the Sponsor Investors may be added to such Shelf Registration Statement at a later time through the filing of a prospectus supplement rather than a post-effective amendment. If the Company has filed any Automatic Shelf Registration Statement for the benefit of the holders of any of its securities other than the Holders, the Company shall, at the request of the Sponsor Investors, file any post-effective amendments necessary to include therein all disclosure and language necessary to ensure that the holders of Registrable Securities may be added to such Shelf Registration Statement.

(d) Additional Information. The Company may require each seller of Registrable Securities as to which any registration is being effected to furnish the Company such information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request in writing, as a condition to such seller’s participation in such registration.

(e) In-Kind Distributions. If any Sponsor Investor (and/or any of their Affiliates) seeks to effectuate an in-kind distribution of all or part of their Registrable Securities to their respective direct or indirect equityholders, the Company will, subject to any applicable lock-ups, work with the foregoing Persons to facilitate such in-kind distribution in the manner reasonably requested and consistent with the Company’s obligations under the Securities Act.

(f) Suspended Distributions. Each Person participating in a registration hereunder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4(a)(vi), such Person will immediately discontinue the disposition of its Registrable Securities pursuant to the registration statement until such Person’s receipt of the copies of of a supplemented or amended prospectus as contemplated by Section 4(a)(vi), subject to the Company’s compliance with its obligations under Section 4(a)(vi).

(g) Other. To the extent that any of the Participating Sponsor Investors is or may be deemed to be an “underwriter” of Registrable Securities pursuant to any SEC comments or policies, the Company agrees that (i) the indemnification and contribution provisions contained in Section 6 shall be applicable to the benefit of such Participating Sponsor Investor in their role as an underwriter or deemed underwriter in addition to their capacity as a holder and (ii) such Participating Sponsor Investor shall be entitled to conduct the due diligence which they would normally conduct in connection with an offering of securities registered under the Securities Act, including without limitation receipt of customary opinions and comfort letters addressed to such Participating Sponsor Investor.

The Company will indemnify and hold harmless, to the fullest extent permitted by law and without limitation as to time, each Holder, such Holder’s officers, directors employees, agents, fiduciaries, stockholders, managers, partners, members, affiliates, direct and indirect equityholders, consultants and representatives, and any successors and assigns thereof, and each Person who controls such holder (within the meaning of the Securities Act) (the “Indemnified Parties”) against all losses, claims, actions, damages, liabilities and expenses (including with respect to actions or proceedings, whether commenced or threatened, and including reasonable attorney fees and expenses) (collectively, “Losses”) caused by, resulting from, arising out of, based upon or related to any of the following (each, a “Violation”) by the Company: (i) any untrue or alleged untrue statement of material fact contained in (A) any registration statement, prospectus, preliminary prospectus or Free-Writing Prospectus, or any amendment thereof or supplement thereto or (B) any application or other document or communication (in this Section 6, collectively called an “application”) executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify any securities covered by such registration under the “blue sky” or securities laws thereof, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance. In addition, the Company will reimburse such Indemnified Party for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such Losses. Notwithstanding the foregoing, the Company will not be liable in any such case to the extent that any such Losses result from, arise out of, are based upon, or relate to an untrue statement, or omission , made in such registration statement, any such prospectus, preliminary prospectus or Free-Writing Prospectus or any amendment or supplement thereto, or in any application, in reliance upon, and in conformity with, written information prepared and furnished in writing to the Company by such Indemnified Party expressly for use therein or by such Indemnified Party’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such Indemnified Party with a sufficient number of copies of the same. In connection with an underwritten offering, the Company will indemnify such underwriters, their officers and directors, and each

-12-

Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Indemnified Parties or as otherwise agreed to in the underwriting agreement executed in connection with such underwritten offering. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of such securities by such seller.

(b) By Holders. In connection with any registration statement in which a Holder is participating, each such Holder will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, will indemnify the Company, its officers, directors, employees, agents and representatives, and each Person who controls the Company (within the meaning of the Securities Act) against any Losses resulting from (as determined by a final and appealable judgment, order or decree of a court of competent jurisdiction) any untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided that the obligation to indemnify will be individual, not joint and several, for each Holder and will be limited to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such registration statement.

(c) Claim Procedure. Any Person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice will impair any Person’s right to indemnification hereunder only to the extent such failure has prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicted indemnified parties will have a right to retain one separate counsel, chosen by the majority of the conflicted indemnified parties involved in the indemnification and approved by the Sponsor Investor, at the expense of the indemnifying party.

(d) Contribution. If the indemnification provided for in this Section 6 is held by a court of competent jurisdiction to be unavailable to, or is insufficient to hold harmless, an indemnified party or is otherwise unenforceable with respect to any Loss referred to herein, then such indemnifying party will contribute to the amounts paid or payable by such indemnified party as a result of such Loss, (i) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection with the statements or omissions which resulted in such Loss as well as any other relevant equitable considerations or (ii) if the allocation provided by clause (i) of this Section 6(d) is not permitted by applicable law, then in such proportion as is appropriate to reflect not only such relative fault but also the relative benefit of the Company on the one hand and of the sellers of Registrable Securities and any other sellers participating in the registration statement on the other in connection with the statement or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided that the maximum amount of liability in respect of such contribution will be limited, in the case of each seller of Registrable Securities, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to such registration.

-13-

The relative fault of the indemnifying party and of the indemnified party will be determined by reference to, among other things, whether the untrue (or, as applicable alleged) untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just or equitable if the contribution pursuant to this Section 6(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account such equitable considerations. The amount paid or payable by an indemnified party as a result of the Losses referred to herein will be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject hereof. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Release. No indemnifying party will, except with the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(f) Non-exclusive Remedy; Survival. The indemnification and contribution provided for under this Agreement will be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract (and the Company and its Subsidiaries shall be considered the indemnitors of first resort in all such circumstances to which this Section 6 applies) and will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of Registrable Securities and the termination or expiration of this Agreement.

Section 7 Cooperation with Underwritten Offerings. No Person may participate in any underwritten registration hereunder unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including, without limitation, pursuant to the terms of any over-allotment or “green shoe” option requested by the underwriters; provided that no Holder will be required to sell more than the number of Registrable Securities such Holder has requested to include in such registration) and (ii) completes, executes and delivers all questionnaires, powers of attorney, stock powers, custody agreements, indemnities, underwriting agreements and other documents and agreements required under the terms of such underwriting arrangements or as may be reasonably requested by the Company and the lead managing underwriter(s). To the extent that any such agreement is entered into pursuant to, and consistent with, Section 3, Section 4 and/or this Section 7, the respective rights and obligations created under such agreement will supersede the respective rights and obligations of the Holders, the Company and the underwriters created thereby with respect to such registration.

Section 8 Subsidiary Public Offering.

(a) Subsidiary Public Offering. If, after an initial Public Offering of the common equity securities of one of its Subsidiaries, the Company distributes securities of such Subsidiary to its equityholders, then the rights and obligations of the Company pursuant to this Agreement will apply, mutatis mutandis, to such Subsidiary, and the Company will cause such Subsidiary to comply with such Subsidiary’s obligations under this Agreement as if it were the Company hereunder.

-14-

Section 9 Joinder; Additional Parties; Transfer of Registrable Securities.

(a) Joinder. The Company may from time to time (with the prior written consent of the Sponsor Investors) permit any Person who acquires Common Equity (or rights to acquire Common Equity) to become a party to this Agreement and to be entitled to and be bound by all of the rights and obligations as a Holder by obtaining an executed joinder to this Agreement from such Person in the form of Exhibit B attached hereto (a “Joinder”). Upon the execution and delivery of a Joinder by such Person, the Common Equity held by such Person shall become the category of Registrable Securities (i.e. Sponsor Investor, Executive or Other Investor Registrable Securities), and such Person shall be deemed the category of Holder (i.e. Sponsor Investor, Executive or Other Investor), in each case as set forth on the signature page to such Joinder.

(b) Restrictions on Transfers. Prior to transferring any Registrable Securities to any Person (including, without limitation, by operation of law), the transferring Holder must first obtain the prior written consent of the Sponsor Investor, and if so obtained, cause the prospective transferee to execute and deliver to the Company a Joinder, except that such consent and Joinder shall not be required in the case of (i) a transfer to the Company, (ii) a transfer by any Sponsor Investor to its partners or members, (iii) a Public Offering, (iv) a sale pursuant to Rule 144 after the completion of the initial Public Offering and/or (v) a transfer in connection with a Sale of the Company. Any transfer or attempted transfer of Registrable Securities in violation of any provision of this Agreement will be void, and the Company will not record such transfer on its books or treat any purported transferee of such Registrable Securities as the owner thereof for any purpose (but the Company will be entitled to enforce against such Person the obligations hereunder).

(c) Legend. Each certificate (if any) evidencing any Registrable Securities and each certificate issued in exchange for or upon the transfer of any Registrable Securities (unless such Registrable Securities would no longer be Registrable Securities after such transfer) will be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER AND OTHER PROVISIONS SET FORTH IN A REGISTRATION RIGHTS AGREEMENT DATED AS OF _________ __, 20__ AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S EQUITYHOLDERS, AS AMENDED. A COPY OF SUCH AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

The Company will imprint such legend on certificates evidencing Registrable Securities outstanding prior to the date hereof. The legend set forth above will be removed from the certificates evidencing any securities that have ceased to be Registrable Securities.

Section 10 General Provisions.

(a) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company and the Sponsor Investors; provided that no such amendment, modification or waiver that would treat a specific Holder or group of Holders of Registrable Securities (i.e., Executives or Other Investors) in a manner materially and adversely different than any other Holder or group of Holders will be effective against such Holder or group of Holders without the consent of the holders of a majority of the Registrable Securities

-15-

that are held by the group of Holders that is materially and adversely affected thereby. The failure or delay of any Person to enforce any of the provisions of this Agreement will in no way be construed as a waiver of such provisions and will not affect the right of such Person thereafter to enforce each and every provision of this Agreement in accordance with its terms. A waiver or consent to or of any breach or default by any Person in the performance by that Person of his, her or its obligations under this Agreement will not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement.

(b) Remedies. The parties to this Agreement will be entitled to enforce their rights under this Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party will be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

(c) Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any jurisdiction, such prohibition, invalidity, illegality or unenforceability will not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein.

(d) Entire Agreement. Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way.

(e) Successors and Assigns. Except as otherwise provided herein, this Agreement will bind and inure to the benefit and be enforceable by the Company and its successors and permitted assigns and the Holders and their respective successors and permitted assigns (whether so expressed or not).

(f) Notices. Any notice, demand or other communication to be given under or by reason of the provisions of this Agreement will be in writing and will be deemed to have been given (i) when delivered personally to the recipient, (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient; but if not, then on the next Business Day, (iii) one Business Day after it is sent to the recipient by reputable overnight courier service (charges prepaid) or (iv) three Business Days after it is mailed to the recipient by first class mail, return receipt requested. Such notices, demands and other communications will be sent to the Company at the address specified on the signature page hereto or any Joinder and to any holder, or at such address or to the attention of such other Person as the recipient party has specified by prior written notice to the sending party. Any party may change such party’s address for receipt of notice by giving prior written notice of the change to the sending party as provided herein.

(h) Governing Law. The corporate law of the State of Delaware will govern all issues and questions concerning the relative rights of the Company and its equityholders. All other issues and questions concerning the construction, validity, interpretation and enforcement of this Agreement and the exhibits and schedules hereto will be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In furtherance of the foregoing, the internal law of the State of Delaware will control the interpretation and construction of this Agreement (and all schedules and exhibits hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

(i) MUTUAL WAIVER OF JURY TRIAL. AS A SPECIFICALLY BARGAINED FOR INDUCEMENT FOR EACH OF THE PARTIES HERETO TO ENTER INTO THIS AGREEMENT (AFTER HAVING THE OPPORTUNITY TO CONSULT WITH COUNSEL), EACH PARTY HERETO EXPRESSLY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY LAWSUIT OR PROCEEDING RELATING TO OR ARISING IN ANY WAY FROM THIS AGREEMENT OR THE MATTERS CONTEMPLATED HEREBY.

EACH OF THE PARTIES HERETO FURTHER AGREES THAT SERVICE OF ANY PROCESS, SUMMONS, NOTICE OR DOCUMENT BY U.S. REGISTERED MAIL TO SUCH PARTY’S RESPECTIVE ADDRESS SET FORTH ABOVE WILL BE EFFECTIVE SERVICE OF PROCESS FOR ANY ACTION, SUIT OR PROCEEDING WITH RESPECT TO ANY MATTERS TO WHICH IT HAS SUBMITTED TO JURISDICTION IN THIS PARAGRAPH.

-17-

(k) No Recourse. Notwithstanding anything to the contrary in this Agreement, the Company and each Holder agrees and acknowledges that no recourse under this Agreement or any documents or instruments delivered in connection with this Agreement, will be had against any current or future director, officer, employee, general or limited partner or member of any Holder or any Affiliate or assignee thereof, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever will attach to, be imposed on or otherwise be incurred by any current or future officer, agent or employee of any Holder or any current or future member of any Holder or any current or future director, officer, employee, partner or member of any Holder or of any Affiliate or assignee thereof, as such for any obligation of any Holder under this Agreement or any documents or instruments delivered in connection with this Agreement for any claim based on, in respect of or by reason of such obligations or their creation.

(l) Descriptive Headings; Interpretation. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement. The use of the word “including” in this Agreement will be by way of example rather than by limitation.

(n) Counterparts. This Agreement may be executed in multiple counterparts, any one of which need not contain the signature of more than one party, but all such counterparts taken together will constitute one and the same agreement.

(o) Electronic Delivery. This Agreement, the agreements referred to herein, and each other agreement or instrument entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent executed and delivered by means of a photographic, photostatic, facsimile or similar reproduction of such signed writing using a facsimile machine or electronic mail will be treated in all manner and respects as an original agreement or instrument and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto will re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument will raise the use of a facsimile machine or electronic mail to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or electronic mail as a defense to the formation or enforceability of a contract and each such party forever waives any such defense.

(p) Further Assurances. In connection with this Agreement and the transactions contemplated hereby, each Holder agrees to execute and deliver any additional documents and instruments and perform any additional acts that may be necessary or appropriate to effectuate and perform the provisions of this Agreement and the transactions contemplated hereby.

If at any time or from time to time there is any change in the capital structure of the Company by way of a stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment will be made in the provisions hereof so that the rights and privileges granted hereby will continue.

-18-

(s) Current Public Information. At all times after the Company has filed a registration statement with the SEC pursuant to the requirements of either the Securities Act or the Exchange Act, the Company will file all reports required to be filed by it under the Securities Act and the Exchange Act and will take such further action as the Sponsor Investors may reasonably request, all to the extent required to enable such Holders to sell Registrable Securities pursuant to Rule 144.

Exhibit 10.1

DIRECTOR NOMINATION AGREEMENT

THIS DIRECTOR NOMINATION AGREEMENT (this “Agreement”) is made and entered into as of July 2, 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.

3

(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 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.

10. Jurisdiction. 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.
