If this Agreement is terminated by the Representative pursuant to Section 9 hereof or if the sale of the Shares provided for herein is not consummated by reason of any failure, refusal or inability on the part of the Company or the Selling Shareholders to perform any agreement on its or their part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company or the Selling Shareholders is not fulfilled, the Company or such Selling Shareholder will reimburse the several Underwriters for all out-of-pocket accountable disbursements (including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges) incurred by the Underwriters in connection with their investigation, preparing to market and marketing the Shares or in contemplation of performing their obligations hereunder.

The Company will not, without the prior written consent of Piper Sandler & Co., from the date of execution of this Agreement and continuing to and including the date 180 days after the date of the Prospectus (the “Lock-Up Period”), (A) offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, or file with or confidentially submit to the Commission a registration statement under the Act relating to, any securities of the Company that are substantially similar to the Shares, including but not limited to any options or warrants to purchase shares of Common Stock or any securities that are convertible into or exchangeable for, or that represent the right to receive, Common Stock or any such substantially similar securities, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing; or (B) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other securities, whether any such transaction described in clause (A) or (B) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.

The restrictions described above do not apply to (A) the Shares to be sold hereunder; (B) the issuance of shares of Common Stock or securities convertible into or exercisable for shares of Common Stock pursuant to the conversion or exchange of convertible or exchangeable securities, or the exercise of warrants or options (including through net exercise), in each case outstanding on the date of this Agreement; or (C) the sale or issuance of, or entry into an agreement to sell or issue, shares of Common Stock or any Related Securities (as defined below) in connection with one or more mergers, acquisitions of securities, businesses, property or other assets or products, joint ventures, commercial relationships or other strategic corporate transactions or alliances.

If Piper Sandler & Co., in its sole discretion, agrees to release or waive the restrictions of any Lock-Up Agreement between an officer or director of the Company and Piper Sandler & Co. provides the Company with notice of the impending release or waiver at least three business days before the effective date of such release or waiver, the Company agrees to announce the impending release or waiver by means of a press release substantially in the form of Exhibit D hereto, issued through a major news service, at least two business days before the effective date of the release or waiver.

Any such free writing prospectus consented to by the Company and Piper Sandler & Co. is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an issuer free writing prospectus, and has complied and will comply with the requirements of Rules 164 and 433 of the Rules and Regulations applicable to any Permitted Free Writing Prospectus. The Company represents that it has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show. Each Underwriter severally represents and agrees that, (A) unless it obtains the prior written consent of the Company and Piper Sandler & Co., it has not distributed, and will not distribute any Written Testing-the-Waters Communication other than those listed on Schedule VI hereto, and (B) any Testing-the-Waters Communication undertaken by it was with entities that are qualified institutional buyers within the meaning of Rule 144A under the Act or institutions that are accredited investors within the meaning of Rule 501 under the Act.

(a) Required Filings; Absence of Certain Commission Actions. All filings required by Rules 424, 430A and 433 of the Rules and Regulations shall have been timely made (without reliance on Rule 424(b)(8) or Rule 164(b)); no stop order suspending the effectiveness of the Registration Statement or any part thereof or any amendment thereof, nor suspending or preventing the use of the Time of Sale Disclosure Package, the Prospectus or any issuer free writing prospectus shall have been issued; no proceedings for the issuance of such an order shall have been initiated or threatened; and any request of the Commission for additional information (to be included in the Registration Statement, the Time of Sale Disclosure Package, the Prospectus, any issuer free writing prospectus or otherwise) shall have been complied with to your satisfaction.

(b) Continued Compliance with Securities Laws. No Underwriter shall have advised the Company that (i) the Registration Statement or any amendment thereof or supplement thereto contains an untrue statement of a material fact which, in your opinion, is material or omits to state a material fact which, in your opinion, is required to be stated therein or necessary to make the statements therein not misleading, or (ii) the Time of Sale Disclosure Package or the Prospectus, or any amendment thereof or supplement thereto, or any issuer free writing prospectus contains an untrue statement of fact which, in your opinion, is material, or omits to state a fact which, in your opinion, is material and is required to be stated therein, or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.

(c) Absence of Certain Events. Except as contemplated in the Time of Sale Disclosure Package and in the Prospectus, subsequent to the respective dates as of which information is given in the Time of Sale Disclosure Package and the Prospectus, neither the Company nor any of its subsidiaries shall have incurred any material liabilities or obligations, direct or contingent, or entered into any material transactions, or declared or paid any dividends or made any distribution of any kind with respect to its capital stock (other than dividends of the Bank paid or declared to be paid to the Company); and there shall

not have been any change in the capital stock (other than a change in the number of outstanding shares of Common Stock due to the issuance of shares upon the exercise of outstanding options or warrants or conversion of convertible securities), or any material change in the short-term or long-term debt of the Company (other than as a result of the conversion of convertible securities), or any issuance of options, warrants, convertible securities or other rights to purchase the capital stock of the Company or any of its subsidiaries, or any Material Adverse Effect or any development involving a prospective Material Adverse Effect (whether or not arising in the ordinary course of business), that, in any such case described in this paragraph, in your judgment, makes it impractical or inadvisable to offer or deliver the Shares on the terms and in the manner contemplated in the Time of Sale Disclosure Package and in the Prospectus.

6. Indemnification and Contribution.

(a) Indemnification by the Company and the Bank. The Company and the Bank, jointly and severally, agree to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the 430A Information and any other information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any issuer free writing prospectus, any issuer information that the Company has filed or is required to file pursuant to Rule 433(d) of the Rules and Regulations, or any Written Testing-the-Waters Communication, or any road show as defined in Rule 433(h) under the Act (a “road show”), (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any investigation or proceeding by any governmental authority, commenced or threatened (whether or not any Underwriter is a target of or party to such investigation or proceeding); and the Company and the Bank will reimburse each Underwriter for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses

reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that neither the Company nor the Bank will be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company and the Bank by you, or by any Underwriter through you, specifically for use in the preparation thereof; it being understood and agreed that (x) the only information furnished by an Underwriter consists of the information described as such in Section 6(g), and (y) the neither the Company nor the Bank will be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from the Selling Shareholder Information.

The Company and the Bank, jointly and severally, agree to indemnify and hold harmless the Designated Underwriter and each person, if any, who controls the Designated Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act (the “Designated Entities”), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to Directed Stock Participants in connection with the Directed Stock Program or caused by 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; (ii) caused by the failure of any Directed Stock Participant to pay for and accept delivery of Directed Stock that the Directed Stock Participant agreed to purchase; (iii) related to, arising out of, or in connection with the Directed Stock Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of the Designated Entities; or (iv) resulting from the violation of any applicable laws or regulations of any foreign jurisdictions where Directed Stock has been offered. Under no circumstances will the Designated Entities be liable to the Company, the Bank or to any Directed Stock Participant for any action taken or omitted to be taken in connection with the Directed Stock or any transaction effected with any Directed Stock Participant, except to the extent found in a final judgment by a court of competent jurisdiction (not subject to further appeal) to have resulted from the gross negligence or willful misconduct of the Designated Entities.

(b) Indemnification by the Selling Shareholders. Each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of such Selling Shareholder), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the 430A Information and any other information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any issuer free writing prospectus, any issuer information that the Company has filed or is required to file pursuant to Rule 433(d) of the Rules and Regulations, or any Written Testing-the-Waters Communication, or any road show, or (ii) arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that (x) a Selling Shareholder shall be liable in any such case only to the extent that any such loss, claim, damage, liability or action is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with the Selling Shareholder Information, and (y) in no event shall any Selling Shareholder’s

aggregate liability under this Section 6(b) exceed the aggregate amount of net proceeds (after deducting Underwriters’ discounts and commissions) received by such Selling Shareholder from the sale of the Securities pursuant to this Agreement as set forth on the cover page of the Prospectus.

(c) Indemnification by the Underwriters. Each Underwriter will, severally and not jointly, indemnify and hold harmless the Company and each Selling Shareholder, its affiliates, directors and officers and each person, if any, who controls the Company and each Selling Shareholder within the meaning of Section 15 of the Act and Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities to which the Company and the Selling Shareholder may become subject, under the Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any issuer free writing prospectus, any issuer information that the Company has filed or is required to file pursuant to Rule 433(d) of the Rules and Regulations, or any Written Testing-the-Waters Communication, or any road show, or (ii) arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in conformity with written information furnished to the Company by you, or by such Underwriter through you, specifically for use in the preparation thereof (it being understood and agreed that the only information furnished by an Underwriter consists of the information described as such in Section 6(g)), and will reimburse the Company and the Selling Shareholder for any legal or other expenses reasonably incurred by the Company or any such Selling Shareholder in connection with investigating or defending against any such loss, claim, damage, liability or action as such expenses are incurred.

(d) Notice and Procedures. Promptly after receipt by an indemnified party under subsection (a), (b) or (c) of this Section 6 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure (through the forfeiture of substantive rights or defenses). In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that if, in the sole judgment of the Representative, it is advisable for the Underwriters to be represented as a group by separate counsel, the Representative shall have the right to employ a single counsel (in addition to local counsel) to represent the Representative and all Underwriters who may be subject to liability arising from any claim in respect of which indemnity may be sought by the Underwriters under subsection (a) or (b) of this Section 6, in which event the reasonable fees and expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the Underwriters as incurred. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to the last paragraph in Section 6(a) hereof in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for the Designated Entities for the defense of any losses, claims, damages and liabilities arising out of the Directed Stock Program if representation of the Underwriters and the Designated Entities by the same counsel would be inappropriate

due to actual or potential differing interests between them. An indemnifying party shall not be obligated under any settlement agreement relating to any action under this Section 6 to which it has not agreed in writing. In addition, no indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld or delayed) effect any settlement of any pending or threatened proceeding unless such settlement includes an unconditional release of such indemnified party for all liability on claims that are the subject matter of such 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 an indemnified party.

(e) Contribution; Limitations on Liability; Non-Exclusive Remedy. If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) of this Section 6, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) of this Section 6, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Bank and the Selling Shareholders, on the one hand, and the Underwriters on the other from the offering of the Shares 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, the Bank and the Selling Shareholders, on the one hand, and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Bank and the Selling Shareholders, on the one hand, and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, the Bank and the Selling Shareholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault 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, the Bank, the Selling Shareholders or the Underwriters and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Bank, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (e) 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 which does not take account of the equitable considerations referred to in the first sentence of this subsection (e). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall 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 of this subsection (e). Notwithstanding the provisions of this subsection (e), (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the Shares 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 and (ii) in no event shall any Selling Shareholder’s aggregate liability under this subsection (e) exceed the aggregate amount of net proceeds (after deducting Underwriters’ discounts and commissions) received by such Selling Shareholder from the sale of the Securities pursuant to this Agreement as set forth on the cover page of the Prospectus. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Selling Shareholders’ obligations in this subsection (e) to contribute are several in proportion to their respective aggregate amount of net proceeds received by such Selling Shareholder (after deducting Underwriters’ discounts and commissions) from the sale of the Securities pursuant to this Agreement as set forth on the cover page of the Prospectus and not joint. The remedies

provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that might otherwise be available to any indemnified party at law or in equity.

(f) [Reserved]

(g) Information Provided by the Underwriters. The Underwriters severally confirm and the Company and each Selling Shareholder acknowledges that the statements with respect to the public offering of the Shares by the Underwriters set forth under the headings “Discounts and Expenses,” “Price Stabilization, Short Positions and Penalty Bids,” “Passive Market Making,” and “Electronic Distribution,” each under the caption “Underwriting” in the Time of Sale Disclosure Package and in 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 Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any issuer free writing prospectus.

7. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company, the Bank and the Selling Shareholders herein or in certificates delivered pursuant hereto, and the agreements of the several Underwriters, the Company, the Bank and the Selling Shareholders contained in Section 6 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof, or the Company, the Bank or any of their respective officers, directors, or controlling persons, or any Selling Shareholders or any controlling person thereof, and shall survive delivery of, and payment for, the Shares to and by the Underwriters hereunder and any termination of this Agreement.

8. Substitution of Underwriters.

(a) Obligation to Purchase Under Certain Circumstances. If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased does not aggregate more than 10% of the total amount of Firm Shares set forth in Schedule II hereto, the remaining Underwriters shall be obligated to take up and pay for (in proportion to their respective underwriting obligations hereunder as set forth in Schedule II hereto except as may otherwise be determined by you) the Firm Shares that the withdrawing or defaulting Underwriters agreed but failed to purchase.

(b) Termination Under Certain Circumstances. If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased aggregates more than 10% of the total amount of Firm Shares set forth in Schedule II hereto, and arrangements satisfactory to you for the purchase of such Firm Shares by other persons are not made within 36 hours thereafter, this Agreement shall terminate. In the event of any such termination neither the Company nor any Selling Shareholder shall be under any liability to any Underwriter (except to the extent provided in Section 4(a)(vii), Section 4(b)(i), Section 4(b)(ii), and Section 6 hereof) nor shall any Underwriter (other than an Underwriter who shall have failed, otherwise than for some reason permitted under this Agreement, to purchase the amount of Firm Shares agreed by such Underwriter to be purchased hereunder) be under any liability to the Company or the Selling Shareholders (except to the extent provided in Section 6 hereof).

As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 8.

referred to below

c/o Piper Sandler & Co.

800 Nicollet Mall, Suite 800

Minneapolis, MN 55402

Dear Sirs and Madams:

As an inducement to the underwriters (the “Underwriters”) to execute an underwriting agreement (the “Underwriting Agreement”) providing for a public offering (the “Offering”) of common stock, $1.00 par value per share (“Common Stock”), of CoastalSouth Bancshares, Inc. and any successor (by merger or otherwise) thereto (the “Company”), the undersigned hereby agrees that without, in each case, the prior written consent of Piper Sandler & Co. (“Piper Sandler”), on behalf of the Underwriters, during the period specified in the second succeeding paragraph (the “Lock-Up Period”), the undersigned will not (and will cause any spouse with jointly held shares of Common Stock, any children of the spouse or the undersigned living in the undersigned’s household, any partnership, corporation, trust or other entity within the undersigned’s control that holds Common Stock not to): (1) offer, pledge, announce the intention to sell, 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, make any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into, exercisable or exchangeable for or that represent the right to receive shares of Common Stock (including without limitation, shares of Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) whether now owned or hereafter acquired (the “Undersigned’s Securities”); (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of shares of Common Stock or such other securities, in cash or otherwise; (3) 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 shares of Common Stock; or (4) publicly disclose the intention to do any of the foregoing.

The undersigned agrees that the foregoing restrictions preclude the undersigned from engaging in any hedging or other transaction which is designed to, or which reasonably could be expected to lead to, or result in a sale or disposition of, the Undersigned’s Securities even if such Securities would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Securities or with respect to any security that includes, relates to, or derives any significant part of its value from such Securities. Notwithstanding the foregoing, the undersigned may pledge the Undersigned’s Securities pursuant to a bona fide pledge arrangement, providedthat before entering into such an arrangement the pledgee agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement.

The Lock-Up Period will commence on the date of this Agreement and continue and include the date that is 180 days after the date of the final prospectus used to sell shares of Common Stock in the Offering pursuant to the Underwriting Agreement, to which you are or expect to become parties.

If the undersigned is an officer or director of the Company, (i) Piper Sandler 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, Piper Sandler 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 issuing a 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 Piper Sandler hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if both (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 letter that are applicable to the transferor, to the extent and for the duration that such terms remain in effect at the time of the transfer. The undersigned further agrees that the foregoing provisions shall be equally applicable to any shares of issuer-directed Common Stock that the undersigned may purchase in the Offering.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Securities:

(i) as a bona fide gift or gifts;

(ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned;

(iii) if the undersigned is a trust, transfers to the beneficiary of such trust;

(iv) transfers by testate succession or intestate succession;

(v) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity (1) transfers to another corporation, partnership, limited liability company, trust or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned (including other investment funds under common control with the undersigned) or (2) distributions of shares of Common Stock or any security convertible into or exercisable for Common Stock to partners (including limited partners), limited liability company members or shareholders of the undersigned;

(vi) by operation of law, such as pursuant to a qualified domestic order, divorce settlement, divorce decree or separation agreement;

(vii) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i)-(vi);

(viii) pursuant to a bona fide third-party tender offer for securities of the Company, merger, consolidation or other similar transaction if approved by the Board of Directors of the Company;

(ix) in a “block” trade (as defined in Rule 10b-18 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)); or

(x) pursuant to the Underwriting Agreement;

provided, that (x) such transfer shall not involve a disposition for value (except in the case of transfers that would be permissible under clauses (iv), (v), (vi), (viii), (ix) or (x) above), (y) the transferee agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement (except in the case of transfers that would be permissible under clauses (viii) or (x) above), and (z) no filing by any party under Section 16(a) of the Exchange Act, other than filings required to be made by such party under the Exchange Act, or other public announcement shall be made voluntarily in connection with such transfer or distribution and any required filing shall clearly indicate in a footnote thereto the circumstances of the particular transfer. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

In addition, the foregoing restrictions shall not apply to (i) the exercise or settlement of stock options, restricted stock units, or other equity awards granted pursuant to the Company’s equity incentive plans; provided that it shall apply to any of the Undersigned’s Securities issued upon such exercise, (ii) any transfer to the Company to satisfy any tax withholding obligations of the Company or the undersigned, or to satisfy the exercise price of stock options by the undersigned, upon the exercise of stock options or other similar share-based awards that are granted pursuant to the Company’s equity incentive plans and outstanding as of the date of the Underwriting Agreement or (iii) the establishment of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; providedthat (a) no sales of the Undersigned’s Securities shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period, and (b) to the extent a public announcement or filing under the Exchange Act, if any, is required of, or voluntarily made by the undersigned regarding the establishment of, such Plan, such announcement or filing shall include a statement to the effect that no transfer of the Undersigned’s Securities may be made under such Plan during the Lock-Up Period.

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 or shares of Common Stock held by the undersigned’s immediate family, if any, except in compliance with the foregoing restrictions. In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby further authorized to decline to make any transfer of shares of Common Stock if such transfer would constitute a violation or breach of this Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and that upon request, the undersigned will execute any additional documents necessary to ensure the validity or enforcement of this Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that the undersigned shall be released from all obligations under this Agreement if (i) the Company notifies the Underwriters that it does not intend to proceed with the Offering, (ii) the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, or (iii) the Offering is not completed by December 31, 2025.

The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Offering in reliance upon this Agreement.

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

Very truly yours,
