In the case of any such separate firm for the Company, LifeStance TopCo and such directors of the Company or LifeStance TopCo, officers of the Company who sign the Registration Statement and control persons of the Company or LifeStance TopCo, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Stockholders and such control persons of any Selling Stockholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Stockholders under the Powers of Attorney. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third

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

(e) To the extent the indemnification provided for in Section 11(a) or 11(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 11(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 11(d)(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 and/or LifeStance TopCo 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 benefits received by the Selling Stockholders 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 Selling Stockholders 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 each Seller or LifeStance TopCo on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Sellers or LifeStance TopCo 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. The Sellers’ respective obligations to contribute pursuant to this Section 11 are several in proportion to the respective number of Shares they have sold hereunder, and not joint. Notwithstanding the foregoing provisions, the liability of each Selling Stockholder under the contribution agreement contained in this Section 11(e) and the indemnity agreement contained in Section 11(b) shall be limited in the aggregate to an amount equal to the Selling Stockholder Proceeds of such Selling Stockholder.

(f) The Sellers, LifeStance TopCo and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and

liabilities referred to in Section 11(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company, LifeStance TopCo and the Selling Stockholders 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, any person controlling any Underwriter or any affiliate of any Underwriter, by or on behalf of any Selling Stockholder or any person controlling any Selling Stockholder, or by or on behalf of the Company, LifeStance TopCo, their respective officers, directors or partners, as applicable, or any person controlling the Company or LifeStance TopCo and (iii) acceptance of and payment for any of the Shares.

12. 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 or the Nasdaq Global Select Market, (ii) trading of any securities of the Company or LifeStance TopCo 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) a general 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.

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

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of any Seller or LifeStance TopCo to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any Seller or LifeStance TopCo shall be unable to perform its obligations under this Agreement, in each case other than as a result of a termination by the Underwriters pursuant to clauses (i), (iii), (iv) or (v) of Section 12 hereto, the Company and LifeStance TopCo, jointly and severally, 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 and documented by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

14. Entire Agreement. (a) This Agreement represents the entire agreement between the Company, LifeStance TopCo and the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company, LifeStance TopCo and each Selling Stockholder acknowledge that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company, LifeStance TopCo or any of the Selling Stockholders or any other person, (ii) the Underwriters owe the Company, LifeStance TopCo and each Selling Stockholder 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, LifeStance TopCo and each Selling Stockholder, 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, LifeStance TopCo and each Selling Stockholder waive to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

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

15. 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.

16. Counterparts; Electronic Signature. 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. Delivery of an executed Agreement by one party to the other may be made by facsimile, electronic mail or other transmission method as permitted by applicable law, and the parties hereto agree that any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. A party’s electronic signature (complying with the New York Electronic Signatures and Records Act (N.Y. State Tech. §§ 301-309), as amended from time to time, or other applicable law) of this Agreement shall have the same validity and effect as a signature affixed by the party’s hand.

17. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

18. Submission to Jurisdiction; Appointment of Agents for Service. (a) The Non-U.S. Selling Stockholder irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York (the “Specified Courts”) 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 Non-U.S. Selling Stockholder 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 Non-U.S. Selling Stockholder 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 Non-U.S. Selling Stockholder irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

(b) The Non-U.S. Selling Stockholder herby irrevocably appoints [ ], with offices at [ ] as its agent for service of process in any Related Proceeding and agrees that service of process in any such Related Proceeding may be made upon it at the office of such agent. The Non-U.S. Selling Stockholder waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. The Non-U.S. Selling Stockholder represents and warrants that such agent has agreed to act as the Selling Stockholders’ agent for service of process, and each of the Selling Stockholders agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect.

19. Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Non-U.S. Selling Stockholder with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Non-U.S. Selling Stockholder agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Non-U.S. Selling Stockholder an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

20. Taxes. If any sum payable by the Non-U.S. Selling Stockholder under this Agreement is subject to tax in the hands of an Underwriter or taken into account as a receipt in computing the taxable income of that Underwriter (excluding net income taxes on underwriting commissions payable hereunder), the sum payable to the Underwriter under this Agreement shall be increased to such sum as will ensure that the Underwriter shall be left with the sum it would have had in the absence of such tax.

21. 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.

22. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to the Representatives c/o Morgan Stanley & Co. LLC, 1585 Broadway, New York, New York 10036, Attention: Equity Syndicate Desk, with a copy to the Legal Department; Goldman Sachs & Co.

Ladies and Gentlemen:

The undersigned understands that Morgan Stanley & Co. LLC (“Morgan Stanley”), Goldman Sachs & Co. LLC (“Goldman Sachs”), J.P. Morgan Securities LLC and Jefferies LLC (collectively, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with LifeStance Health Group, Inc., a Delaware corporation (the “Company”), and LifeStance TopCo, L.P., providing for the public offering (the “Public Offering”) by the several Underwriters, including the Representatives (collectively, the “Underwriters”), of shares (the “Shares”) of common stock, par value $0.01 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 and Goldman Sachs on behalf of the Underwriters, it will not, will not cause any direct or indirect affiliate to, and will not publicly disclose an intention to, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus (the “Restricted Period”) relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any Class A partnership units or Class B partnership units of LifeStance TopCo, L.P. (the “Partnership Units” and, together with the Common Stock, the “Securities”) or any other securities so owned convertible into or exercisable or exchangeable for any 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 any Securities or any security convertible into or exercisable or exchangeable for Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock, Partnership Units or such other securities, in cash or otherwise. Without limiting any exclusion provided herein, the undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transaction designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition of any Securities, or any securities convertible into or exercisable or exchangeable for 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.

A-1

The restrictions described in the foregoing paragraph shall not apply to:

(g)

dispositions to the Company upon exercise of the Company’s right to repurchase or reacquire the undersigned’s Securities in the event the undersigned ceases to provide services to the Company pursuant to agreements in effect on the date hereof, including without limitation the Company’s Class B unit award agreements, which agreements are described in the registration statement and the Prospectus related to the Public Offering, that permit the Company to repurchase or reacquire, at cost, such securities upon termination of the undersigned’s services to the Company or its affiliates; provided that any filing under Section 16(a) of the Exchange Act relating to such disposition shall clearly indicate in the footnotes thereto that the shares were repurchased or reacquired by the Company;

(i)

In addition, the undersigned agrees that, without the prior written consent of Morgan Stanley and Goldman Sachs 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 Securities or any security convertible into or exercisable or exchangeable for Securities. 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 Securities 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 provisions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the Public Offering.

If the undersigned is an officer or director of the Company, (i) Morgan Stanley and Goldman Sachs agree 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, Morgan Stanley and Goldman Sachs will notify the Company of the impending release or waiver, and (ii) the Company will agree 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 and Goldman Sachs hereunder to any such officer or director of the Company shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration 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.

If, prior to the expiration of the Restricted Period, Morgan Stanley and Goldman Sachs consent at their discretion, on behalf of the Underwriters, to release any Securities held by any directors, officers, shareholders of 1.0% or more of the Securities of the Company from the restrictions of any lock-up arrangement similar to that set forth in this agreement and/or entered into in connection with the Public Offering (any such release being a “Triggering Release” and such party receiving such release being a “Triggering Release Party”), then a number of the undersigned’s Securities subject to this agreement shall also be released from the restrictions set forth herein on a pro rata basis, such number of Securities being the total number of Securities held by the undersigned on the date of the Triggering Release that are subject to this agreement multiplied by a fraction, the numerator of which shall be the number of Securities released pursuant to the Triggering Release and the denominator of which shall be the total number of Securities held by the Triggering Release Party on such date. Notwithstanding the foregoing, such Triggering Release shall not be applied (a) if the aggregate number of shares of Common Stock affected by such discretionary release, waiver, or termination, in whole or in part, excluding any release pursuant to clause (b) below, is less than or equal to 1.0% of the fully-diluted capitalization of the Company as measured immediately prior to the consummation of the Public Offering; (b) with respect to any release granted to a director or officer of the Company due to financial hardship, in any amount and subject to such terms as may be determined by the Morgan Stanley and Goldman Sachs in their sole discretion; or (c) in the event of any primary or secondary public offering or sale of Common Stock that is underwritten (the “Underwritten Sale”) during the Restricted Period in a transaction that complies with the terms of the Underwriting Agreement; provided that if the undersigned has a contractual right to demand or require the registration of the undersigned’s Securities or otherwise “piggyback” on a registration statement filed by the Company for the offer and sale of its Securities, the undersigned is offered the opportunity to participate on a pro rata basis in the Underwritten Sale consistent with such contractual rights and the undersigned is released from its lockup restrictions set forth herein to the extent of the undersigned’s participation in such Underwritten Sale or such contractual rights are waived pursuant to the terms thereof. In the event of a Triggering Release, the Company shall use commercially reasonable efforts to notify the undersigned within five business days of the occurrence of such Triggering Release, which notification obligation may be satisfied by the issuance of a press release through a major news service, or on a Form 8-K, announcing such Triggering Release; provided that the failure by the Company to give such notice shall not give rise to any claim or liability against the Company or Morgan Stanley and Goldman Sachs except, in respect of the Company, in the case of bad faith on the part of the Company.

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

A-4

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

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

Notwithstanding anything to the contrary contained herein, this agreement will automatically terminate and the undersigned will be released from all of his, her or its obligations hereunder upon the earliest to occur, if any, of (i) prior to the execution of the Underwriting Agreement, either the Company on the one hand, or Morgan Stanley and Goldman Sachs, together, on the other hand, advises the other in writing that it has determined not to proceed with the Public Offering, (ii) the withdrawal of the Registration Statement on Form S-1 related to the Public Offering, (iii) the Underwriting Agreement is executed but is terminated (other than the provisions thereof which survive termination) prior to payment for and delivery of the Common Stock to be sold thereunder, or (iv) August 1, 2021, in the event that the Underwriting Agreement has not been executed by such date; provided, however, that the Company may, by written notice to the undersigned prior to such date, extend such date for a period of up to three additional months.

This agreement may be executed and delivered via facsimile, electronic mail (including .pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com or www.echosign.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.

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