Ladies and Gentlemen:

The financial institution listed on Schedule I hereto, in its capacity as selling stockholder (in such capacity, the “Selling Stockholder”), of the Stock (as defined below) of BellRing Brands, Inc., a Delaware corporation (the “Company”), subject to the terms and conditions stated in this Underwriting Agreement (this “Agreement”), proposes to sell to the several Underwriters named in Schedule II hereto (in their capacity as underwriters, the “Underwriters”), for whom you serve as representative (the “Representative”), an aggregate of 4,597,339 shares (the “Stock”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”). This Agreement is to confirm the agreement concerning the purchase of the Stock from the Selling Stockholder by the Underwriters.

On the date hereof and prior to the execution of this Agreement, Post Holdings, Inc., a Missouri corporation (“Post”), entered into an exchange agreement with the Selling Stockholder (or its affiliate) (the “Exchange Agreement”), whereby Post agreed to transfer to the Selling Stockholder the Stock in exchange for the cancellation of certain indebtedness of Post owing to the Selling Stockholder (or its affiliate) (the “Debt-for-Equity Exchange”).

Subject to the sale of the Stock by the Selling Stockholder to the Underwriters in compliance with the terms of this Agreement, the Underwriters have agreed to sell to the Company, and the Company has agreed to herein to purchase from the Underwriters (the “Share Repurchase”), an aggregate of 925,000 shares (the “Repurchase Shares”) pursuant to Section 3 of this Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3ASR (File No. 333-266656), including a prospectus, relating to the Stock. The registration statement as amended at the time it became effective, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A, 430B or 430C under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (the “Securities Act”), is hereinafter referred to as the “Initial Registration Statement.” The base prospectus included in the Registration Statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement is hereinafter referred to as the “Base Prospectus.” Any preliminary prospectus supplement in the form first used to confirm sales of Stock (or in the form made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) relating to the Stock filed with the Commission pursuant to Rule 424(b) of the rules and regulations of the Commission under the Securities Act is hereinafter referred to as the “Preliminary Prospectus.” The various parts of the Initial Registration Statement, including all exhibits to the Initial Registration Statement and including all information contained in the form of final prospectus relating to the Stock filed with the Commission pursuant to Rule 424(b) under the Securities Act and deemed by virtue of Rule 430B under the Securities Act to be part of the Initial Registration Statement, each as amended at the time such part of the Initial Registration Statement became effective, are herein collectively called the “Registration Statement.” If the Company has filed an abbreviated registration statement with respect to the Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term Registration Statement shall be deemed to include such Rule 462 Registration Statement. The final prospectus supplement, in the form first filed pursuant to Rule 424(b) under the Securities Act, is hereinafter called the “Prospectus.” Any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such Base Prospectus, Preliminary Prospectus or Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and incorporated therein; any reference to any amendment to the Registration Statement shall be deemed to refer to and include any annual report of the Company filed pursuant to Section 13(a) or 15(d) of the Exchange Act after the effective date of the Registration Statement that is incorporated by reference in the prospectus contained in the Registration Statement. “Effective Date” means the date and time as of which such registration statement, or the most recent post-effective amendment thereto, became effective, or is deemed to have become effective by the Commission, in accordance with the rules and regulations under the Securities Act.

For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act, “Time of Sale Prospectus” means the Preliminary Prospectus together with the documents and pricing information set forth on Schedule IV and Schedule V hereto, and “broadly available road show” means a “bona fide electronic road show” as defined in Rule 433(h)(5) under the Securities Act that has been made available without restriction to any person. As used herein, the terms “Registration Statement,” “Base Prospectus,” “Preliminary Prospectus,” “Time of Sale Prospectus” and “Prospectus” shall include the documents, if any, incorporated by reference therein as of the date hereof. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Registration Statement, the Base Prospectus, the Time of Sale Prospectus or the Prospectus shall include all documents subsequently filed by the Company with the Commission pursuant to the Exchange Act that are deemed to be incorporated by reference therein.

(a) The Company hereby agrees to indemnify and hold harmless each Underwriter, the Selling Stockholder and their respective affiliates, directors, officers and employees and each person, if any, who controls any Underwriter or the Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which that Underwriter, Selling Stockholder, affiliate, director, officer, employee or controlling person (as applicable) may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) the Base Prospectus, the Time of Sale Prospectus, the Registration Statement, the Prospectus or any amendment or supplement thereto, (B) any free writing prospectus or any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 under the Securities Act) used or referred to by any Underwriter or the Selling Stockholder, (D) any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Stock, including any “road show” (as defined in Rule 433 under the Securities Act) not constituting a free writing prospectus (“Marketing Materials”), or (E) any Blue Sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company) specifically for the purpose of qualifying any or all of the Stock under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (ii) the omission or alleged omission to state in the Time of Sale Prospectus, the Registration Statement, the Prospectus, any free writing prospectus or any amendment or supplement thereto or in any Permitted Issuer Information, any Written Testing-the-Waters Communication, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, and shall reimburse each Underwriter, the Selling Stockholder and each such affiliate, director, officer, employee or controlling person (as applicable) promptly

The foregoing indemnity agreement is in addition to any liability that the Company may otherwise have to (i) any Underwriter or to any affiliate, director, officer, employee or controlling person of that Underwriter or (ii) the Selling Stockholder or to any affiliate, director, officer, employee or controlling person of the Selling Stockholder.

(b) The Selling Stockholder hereby agrees to indemnify and hold harmless each Underwriter, its affiliates, directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock) to which that Underwriter, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises to the extent and in the manner set forth in Section 9(a) above; provided, however, that (i) the Selling Stockholder shall be liable only in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Base Prospectus, the Time of Sale Prospectus, the Registration Statement, the Prospectus, any free writing prospectus or any such amendment or supplement thereto, or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with the Selling Stockholder’s Selling Stockholder Information and (ii) the aggregate amount of the Selling Stockholder’s liability pursuant to this Section 9(b) shall not exceed the amount of the underwriting discount received by it or its affiliate, as applicable, in its or its affiliate’s capacity as an Underwriter hereunder.

(c) Each Underwriter, severally and not jointly, hereby agrees to indemnify and hold harmless the Company and the Selling Stockholder and its and their respective officers, employees, directors and each person, if any, who controls the Company or the Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, the Selling Stockholder or any such director, officer, employee or controlling person (as applicable) may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Time of Sale Prospectus, the Registration Statement, the Prospectus, any free writing prospectus or any amendment or supplement thereto, or any Marketing Materials or Blue Sky Application, or (ii) the omission or alleged omission to state in the Time of Sale Prospectus, the Registration Statement, the Prospectus, any free writing prospectus or any amendment or supplement thereto, or any Marketing Materials or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representative by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 9(g). The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to (i) the Company or any such affiliate, director, officer, employee or controlling person of the Company or (ii) the Selling Stockholder or any such affiliate, director, officer, employee or controlling person of the Selling Stockholder.

(d) Post hereby agrees to indemnify and hold harmless each Underwriter and the Selling Stockholder, their respective affiliates, directors, officers and employees and each person, if any, who controls any Underwriter or the Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock) to which that Underwriter, Selling Stockholder, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises to the extent and in the manner set forth in Section 9(a) above; provided, however, that Post shall be liable only in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Base Prospectus, the Time of Sale Prospectus, the Registration Statement, the Prospectus, any free writing prospectus or any such amendment or supplement thereto, or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with the Post Information. The foregoing indemnity agreement is in addition to any liability that Post may otherwise have to any Underwriter or the Selling Stockholder or to any affiliate, director, officer, employee or controlling person of such Underwriter or the Selling Stockholder.

(e) Promptly after receipt by an indemnified party under paragraph (a), (b), (c) or (d) above of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under paragraph (a), (b), (c) or (d) above, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under paragraph (a), (b), (c) or (d) above except to the extent it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under paragraph (a), (b), (c) or (d) above. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 9 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable and documented costs of investigation; provided, however, that the Underwriters shall have the right to employ counsel to represent jointly the Underwriters and their respective affiliates, directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company, Post and/or the Selling Stockholder, as applicable under this Section 9, but the fees and expenses of such counsel shall be at the expense of the Underwriters unless (i) the Company, Post and/or the Selling Stockholder, as applicable and the Underwriters shall have so mutually agreed; (ii) the Company, Post and/or the Selling Stockholder, as applicable shall have failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriters; (iii) the Underwriters and their respective affiliates, directors, officers, employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from or in addition to those available to the Company, Post and/or the Selling Stockholder, as applicable; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriters or their respective affiliates, directors, officers, employees or controlling persons, on the one hand, and the Company, Post and/or the Selling Stockholder, as applicable, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the reasonable and documented fees and expenses of such separate counsel shall be paid by the Company, Post and/or the Selling Stockholder, as applicable. In no event shall the indemnifying parties be liable for the reasonable fees and expenses of more than one counsel (together with one local counsel in each jurisdiction) at any time for all indemnified parties in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances;

provided that if the use of such counsel chosen to represent all indemnified parties would present such counsel with a conflict of interest, each indemnified party shall have the right to select separate counsel to defend such action on behalf of such indemnified party and the indemnifying party shall be liable for the reasonable and documented fees and expenses of such counsel. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(f) If the indemnification provided for in this Section 9 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 9(a), 9(b), 9(c) and 9(d) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, for which such indemnification would otherwise be available pursuant to its terms, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and Post, on the one hand, and the Underwriters and the Selling Stockholder, on the other, from the offering of the Stock, or (ii) if the allocation provided by clause (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 (i) above but also the relative fault of the Company in one regard, the Selling Stockholder in the second regard, Post in the third regard, and the Underwriters in the fourth regard, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and Post, on the one hand, and the Underwriters and the Selling Stockholder, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Selling Stockholder, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the shares of Stock purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company in one regard, the Selling Stockholder in the second regard, Post in the third regard or the Underwriters in the fourth regard, the intent of the parties and their relative knowledge,

access to information and opportunity to correct or prevent such statement or omission. The Company, Post, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(f) were to be 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 into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 9(f) shall be deemed to include, for purposes of this Section 9(f) and 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(f), (i) in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the discount received by it exceeds the amount of any damages that such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission, and (ii) in no event shall the Selling Stockholder be required to contribute any amount in excess of the amount by which the discount received by it or its affiliate, as applicable, in its or its affiliate’s capacity as an Underwriter hereunder, exceeds any damages which the Selling Stockholder has otherwise been required to pay by reason of any 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 Underwriters’ respective obligations to contribute as provided in this Section 9(f) are several in proportion to their respective underwriting obligations hereunder and not joint.

(g) The Underwriters severally confirm and the Company and the Selling Stockholder, severally and not jointly, acknowledges and agrees that the statements regarding the concession and reallowance figures and the first three paragraphs relating to overallotment, stabilization and covering transactions by the Underwriters appearing under the caption “Underwriting (Conflicts of Interest)—Price Stabilization and Short Positions” in the Time of Sale Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Time of Sale Prospectus, the Registration Statement, the Prospectus, any free writing prospectus or any amendment or supplement thereto, any Blue Sky Application, or any Marketing Materials.

10. Defaulting Underwriters. If any Underwriter or Underwriters default in their obligations to purchase the Stock hereunder and the aggregate number of shares of the Stock that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of the Stock, the Representative may make arrangements satisfactory to the Selling Stockholder for the purchase of such Stock by other persons, including any of the Underwriters, but if no such arrangements are made by the Delivery Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Stock that such defaulting Underwriter agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate number of shares of the Stock with respect to which such default or defaults occur exceeds 10% of the total number of shares of the

Stock and arrangements satisfactory to the Representative and the Selling Stockholder for the purchase of such Stock by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder, except as provided in Section 15. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

11. Termination. Each of the Company and the Selling Stockholder acknowledges and agrees that the obligations of the Underwriters hereunder may be terminated by the Representative by notice given to and received by the Company and the Selling Stockholder prior to delivery of and payment for the Stock by the Underwriters if, prior to that time, any of the events described in Sections 8(i), 8(j) and 8(k) shall have occurred or if the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement.

12. Reimbursement of Underwriters’ Expenses. If (a) the Selling Stockholder shall fail to tender the Stock for delivery to the Underwriters for any reason permitted under this Agreement (including due to the failure by Post to consummate the Debt-for-Equity Exchange pursuant to the Exchange Agreement), or (b) the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement (other than the failure of the condition set forth in Section 8(k) of this Agreement to be satisfied (other than a halt in trading of the securities of the Company)), Post or the Company, as applicable, will reimburse the Underwriters for all reasonable out-of-pocket expenses (including reasonable and documented fees and disbursements of outside counsel for the Underwriters) incurred by the Underwriters in connection with this Agreement and the proposed purchase and sale of the Stock, each to the extent that any such failure or reason is caused by an action, inaction or failure of such party (except that in the case of any failure or reason on the basis of Section 8(k), Post shall reimburse the Underwriters for all such expenses), and upon demand, Post or the Company, as the case may be, shall pay the full amount thereof to the Representative. If this Agreement is terminated pursuant to Section 10 by reason of the default of one or more Underwriters or the Selling Stockholder, Post shall not be obligated to reimburse any defaulting Underwriter on account of those expenses, and in the case of default of the Company or the Selling Stockholder, such defaulting party shall be responsible for reimbursing the Underwriters in accordance with this Section 12. To the extent this Section 12 in any way conflicts with that certain Registration Rights Agreement, dated March 10, 2022, by and among the Company, Post and the other stockholders party thereto (the “Registration Rights Agreement”), such Registration Rights Agreement is modified accordingly. Except as provided in this Section 12, nothing herein is intended to, nor shall it, modify the Registration Rights Agreement in any manner.

13. Research Analyst Independence. Each of the Company and the Selling Stockholder acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict

of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions. Each of the Company and the Selling Stockholder acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

14. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

This Agreement shall inure to the benefit of and be binding upon the Underwriters, Post (solely with respect to Section 2(2), Section 9, Section 12, Section 14 and Section 16), the Company, the Selling Stockholder and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that the representations and warranties (other than those representations and warranties that are expressly made only to a specific party or parties hereto, which shall be for the benefit of such specified party or parties and their respective indemnified persons referred to in Section 9 and their respective successors and assigns), indemnities and agreements contained in this Agreement shall also be deemed to be for the benefit of the other

indemnified persons referred to in Section 9 and their respective successors and assigns. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

16. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, Post, the Selling Stockholder and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of the Stock and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them.

17. Definition of the Terms “Business Day,” “Affiliate” and “Subsidiary.” For purposes of this Agreement, (a) “business day” means any day on which The New York Stock Exchange, Inc. is open for trading, and (b) “affiliate” and “subsidiary” have the meanings set forth in Rule 405 under the Securities Act.

18. Governing 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 laws of the State of New York. The parties hereto agree that any suit or proceeding arising in respect of this Agreement will be tried exclusively in the U.S. District Court of the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York, and the parties hereto agree to submit to the jurisdiction of, and to venue in, such courts.

19. Waiver of Jury Trial. The Company, the Selling Stockholder and the Underwriters hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20. No Fiduciary Duty. Each of the Company and the Selling Stockholder acknowledges and agrees that in connection with this offering, sale of the Stock or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (a) no fiduciary or agency relationship between the Company, the Selling Stockholder and any other person, on the one hand, and the Underwriters, on the other hand, exists; (b) the Underwriters are not acting as advisors, expert or otherwise, to the Company or the Selling Stockholder, including, without limitation, with respect to the determination of the public offering price of the Stock, and such relationship between the Company and the Selling Stockholder, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Underwriters may have to the Company and the Selling Stockholder shall be limited to those duties and obligations specifically stated herein; and (d) the Underwriters and their respective affiliates may have interests that differ from those of the Company and the Selling Stockholder. Each of the Company and the Selling Stockholder hereby waives and agrees not to assert any claims that the Company and the Selling Stockholder may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

The Selling Stockholder further acknowledges and agrees that, although the Underwriters may provide the Selling Stockholder with certain Regulation Best Interest and Form CRS disclosures or other related documentation in connection with the offering of the Stock, the Underwriters are not making a recommendation to the Selling Stockholder to participate in the offering or sell any Stock at the price set forth in Section 3 hereof, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

21. Patriot Act. In accordance with the requirements of the USA PATRIOT Act (Title III of Pub. L, 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their clients, which may include the name and address of their clients, as well as other information that will allow the Underwriters to properly identify their clients.

22. Recognition of the U.S. Special Resolution Regimes. In the event that (a) 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 and (b) 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 ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

23. Entire Agreement. 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 Stock, represents the entire agreement between the Company, the Selling Stockholder and the Underwriters with respect to the preparation of the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Stock.

24. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and 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., ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇) 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. Furthermore, the words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

25. Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.
