Item 1.01. Entry into a Material Definitive Agreement

On September 20, 2022, Southern Missouri Bancorp, Inc., Poplar Bluff, Missouri (“Southern Missouri” or the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Citizens Bancshares, Co., Kansas City, Missouri (“Citizens”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Citizens will merge with and into the Company, with the Company as the surviving corporation (the “Merger”). Immediately after the effective time of the Merger (the “Effective Time”), the Company intends to merge Citizens Bank and Trust Company, a wholly owned subsidiary of Citizens, with and into Southern Bank, a wholly owned subsidiary of the Company, with Southern Bank as the surviving institution (the “Bank Merger”). The Merger Agreement was approved and adopted by the Board of Directors of each of the Company and Citizens. The Merger is expected to be completed in the first calendar quarter of 2023, subject to customary closing conditions discussed below.

Under the terms of the Merger Agreement, unanimously approved by the boards of both entities and assuming no change in the number of issued and outstanding shares of Citizens common stock, Citizens’ shareholders are projected to receive either a fixed exchange ratio of 1.1448 shares of Southern Missouri common stock or a cash payment of $53.50 for each Citizens’ share, at the election of the shareholders, subject to adjustment based on Citizens’ capital and the total outstanding shares of Citizens at closing. Based on Southern Missouri's $52.53 average closing price over the 20-day trading period ended September 19, 2022, the transaction's value is approximately $140.0 million, with merger consideration comprised of stock and cash at a 75:25 ratio. Upon consummation of the Merger, the shareholders of Citizens will own approximately 18% of the combined company. Prior to the Effective Time, each option to purchase shares of Citizens Common Stock (each, a “Citizens Option”), whether vested or unvested, will be cancelled and converted into the right to receive an amount in cash (subject to withholding as provided in the Merger Agreement) equal to the product of (x) $53.50 minus (y) the exercise price per share of the Citizens Option.

The Merger Agreement contains customary representations and warranties from both the Company and Citizens, and each party has agreed to customary covenants, including, among others, covenants relating to (1) the conduct of its business during the interim period between the execution of the Merger Agreement and the Effective Time, including, in the case of Citizens, specific forbearances with respect to its business activities, (2) the obligation of the Company to call a special meeting of its shareholders to approve the issuance of Company Common Stock in the Merger, (3) the obligation of Citizens to call a special meeting of its shareholders to approve the Merger Agreement (the “Citizens Shareholder Meeting”), and, subject to certain exceptions, to recommend that its shareholders approve the Merger Agreement, and (4) Citizens’ non-solicitation obligations relating to alternative acquisition proposals.

The completion of the Merger is subject to customary conditions, including approval of the Merger Agreement by Citizen’s shareholders, approval of the issuance of the shares in the Merger by Company shareholders and the receipt of required regulatory approvals. The Merger currently is anticipated to be completed in the first quarter of calendar 2023.

The Merger Agreement provides certain termination rights for both Southern Missouri and Citizens and further provides that a fee of $5.5 million will be payable by Citizens upon termination of the Merger Agreement under certain circumstances as specified therein. Certain shareholders including board members and executive officers of Citizens have each executed a voting agreement pursuant to which they have agreed to vote their shares of Citizens’ common stock in favor of the Merger Agreement. Certain directors and executive officers of the Company have each executed a voting agreement pursuant to which they have agreed to vote their shares of Southern Missouri common stock in favor of the issuance of the shares in the Merger.

Pursuant to the Merger Agreement, the Company will appoint as a director one individual who had served as a director of Citizens as of the date of the Merger Agreement for a term to expire at the 2025 annual meeting. The Company has not determined who will be appointed at this time.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached to this Current Report on Form 8-K as Exhibit 2.1 and is incorporated herein by reference. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Company or Citizens, their respective affiliates or their respective businesses that will be contained in, or incorporated by reference into, the Registration Statement on Form S-4 that will include a joint proxy statement of the Company and Citizens and a prospectus of the Company as well as in other public filings the Company makes with the Securities and Exchange Commission ("SEC").

The Merger Agreement has been included to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Citizens or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

Item 7.01. Regulation FD Disclosure

On September 20, 2022, the Company and Citizens issued a joint press release announcing the execution of the Merger Agreement. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference. In addition, the Company has prepared an investor presentation regarding the transactions contemplated by the Merger Agreement, which it expects to use in connection with presentations to analysts and investors. The presentation is attached to this Current Report on Form 8-K as Exhibit 99.2 and is incorporated herein by reference.

The information in this Current Report on Form 8-K is furnished pursuant to Item 7.01 and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). It may only be incorporated by reference in another filing under the Exchange Act or the Securities Act of 1933, as amended, if such subsequent filing specifically references the information furnished pursuant to Item 7.01 of this Current Report on Form 8-K.

Note Regarding Forward-Looking Statements.

This report may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 regarding Southern Missouri. Forward-looking statements often include the words “believes,” “expects,” “anticipates,” “estimates,” “forecasts,” “intends,” “plans,” “targets,” “potentially,” “probably,” “projects,” “outlook” or similar expressions or future or conditional verbs such as “may,” “will,” “should,” “would” and “could.” These forward-looking statements are subject to known and unknown risks, uncertainties and other factors that could cause the actual results to differ materially from the forward-looking statements, including, without limitation, the following: the requisite regulatory and shareholder approvals for the Company’s acquisition of Citizens Bancshares Co. which is the 100% owner of Citizens Bank and Trust Company might not be obtained or other conditions to completion of the transaction might not be satisfied or waived; expected cost savings, synergies and other benefits from the Company’s merger and acquisition activities, including the acquisition of Citizens and the Company’s other recently completed acquisition, might not be realized within the anticipated time frames or at all, and costs or difficulties relating to integration matters, including but not limited to customer and

employee retention, might be greater than expected; the strength of the United States economy in general and the strength of the local economies in which the Company conducts operations including unemployment levels and labor shortages; fluctuations in interest rates and inflation, including the effects of a potential recession or slowed economic growth caused by changes in oil prices or supply chain disruptions; monetary and fiscal policies of the Board of Governors of the Federal Reserve System and the U.S. Government and other governmental initiatives affecting the financial services industry; the risks of lending and investing activities, including changes in the level and direction of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for loan losses; the Company’s ability to access cost-effective funding; the timely development of and acceptance of the Company’s new products and services and the perceived overall value of these products and services by users, including the features, pricing and quality compared to competitors’ products and services; fluctuations in real estate values and both residential and commercial real estate markets, as well as agricultural business conditions; demand for loans and deposits in the Company’s market area; legislative or regulatory changes that adversely affect the Company’s business; changes in accounting principles, policies or guidelines; results of examinations of the Company by its regulators, including the possibility that such regulators may, among other things, require the Company to increase its reserve for loan losses or to write-down assets; the impact of technological changes; and the Company’s success at managing the risks involved in the foregoing. Any forward-looking statements are based upon management’s beliefs and assumptions at the time they are made.

Additional factors which could affect the forward- looking statements can be found in the cautionary language included under the headings “Risk Factors” and “Forward-Looking Statements” in the Company’s Annual Report on Form 10-K filed with the SEC for the year ended June 30, 2022, and other documents subsequently filed by the Company with the SEC.

You should not place undue reliance on forward-looking statements and Southern Missouri and Citizens undertake no obligation to update or revise any such statements to reflect circumstances or events that occur after the date on which the forward-looking statement is made, whether as a result of new information, future events or otherwise.

(A)“Assumed Aggregate Merger Consideration” means, for purposes of calculating the Per Share Cash Consideration and the Per Share Stock Consideration, $125.5 million, subject to adjustment pursuant to Section 1.4(c).

(B)“Buyer Common Stock” means the shares of common stock, $0.01 par value, of Buyer.

(C)“Closing Price” means $46.68, the closing sale price (rounded to the nearest one ten thousandth) of Buyer Common Stock on the Nasdaq Stock Market, Inc. (“Nasdaq”) as of May 31, 2022.

(D)“Per Share Cash Consideration” means a cash amount of $53.50, assuming no change in the number of outstanding shares of Seller Common Stock from the date of this Agreement and subject Section 1.4(c).

(E)“Per Share Stock Consideration” means 1.1448 shares of Buyer Common Stock (assuming no change in the number of outstanding shares of Seller Common Stock from the date of this Agreement and subject to Section 1.4(c));

(F)The “Merger Consideration” means the Cash Consideration and/or the Stock Consideration described in this Section, as applicable.

(v)Cancellation of Options. Seller and Buyer shall take all requisite action so that, prior to the Effective Time, each option to purchase shares of Seller Common Stock awarded under the Seller Benefit Plans and outstanding immediately prior to the Effective Time (each, an “Option”), whether vested or unvested, shall be cancelled in connection with the Merger in exchange for an amount of cash for each share of Seller Common Stock subject to the Option equal to (x) $53.50 minus (y) the amount of the exercise price per share of the Option.

All of the shares of Seller Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate previously representing any such shares of Seller Common Stock (each, a “Certificate”), (it being understood that any reference to “Certificate” shall be deemed, as appropriate, to include reference to book-entry account statements relating to the ownership of Seller Common Stock, and it being further understood that provisions herein relating to Certificates shall be interpreted in a manner that appropriately accounts for book-entry shares, including that, in lieu of delivery of a Certificate and a letter of transmittal as specified herein, shares held in book-entry form may be transferred by means of an “agent’s message” to the Exchange Agent or such other similar evidence of transfer as the Exchange Agent may reasonably request), shall thereafter represent only the right to receive the Merger Consideration and/or any cash in lieu of a fractional share interest into which the shares of Seller Common Stock represented by such Certificate have been converted pursuant to this Section 1.4 and Section 2.3(f), as well as any dividends as provided in Section 2.3(c).

(c) (i)For purposes of this Agreement, “Seller’s Capital” means the consolidated equity capital of Seller determined in accordance with GAAP, with the exception of no adjustment of accumulated

other comprehensive income from June 30, 2022 to the Measuring Date (as defined below), adjusted for the after-tax cost of the accrual of any Seller Transaction Expenses (defined below) as of the close of business on the last business day of the month immediately preceding the Effective Time (the “Measuring Date”) which have not already been paid or accrued prior to that time; provided, however, that any termination fees or deconversion fees associated with CB’s data processing agreements will be excluded from the calculation of Seller’s Capital. Section 1.4(c) of the Seller Disclosure Schedule sets forth an example calculation of Seller’s Capital. If a Seller Transaction Expense is not deductible to Seller for income tax purposes, there shall be no adjustment for the tax effect of such item in computing Seller Capital. “Seller Transaction Expenses” means the fees, expenses and costs (i) of accountants, financial advisors, legal counsel and other advisors incurred by Seller and CB in connection with the Mergers and the transactions contemplated thereby, and (ii) for any change in control payments and retention or other payments to any directors, officers or employees of Seller or CB in connection with the Mergers pursuant to agreements between such persons and Seller or CB.

(ii)Adjustment to Merger Consideration.

(A)If Seller’s Capital is greater than $95,000,000 (the “Minimum Capital Requirement”), the Assumed Aggregate Merger Consideration shall be increased dollar for dollar by the amount of such excess.

(B)If Seller’s Capital is less than the Minimum Capital Requirement but greater than or equal to $93,500,000, the Assumed Aggregate Merger Consideration shall be decreased dollar for dollar by the amount by which the Minimum Capital Requirement exceeds Seller’s Capital.

(C)If Seller’s Capital is less than $93,500,000, then, in addition to the adjustment in subsection (B) above, the Assumed Aggregate Merger Consideration shall be further decreased by an amount equal to, the product of (i) the difference between $93,500,000 and Seller’s Capital and (ii) 1.44.

(d)Seller shall, within five business days after the Measuring Date, provide Buyer with a calculation of Seller’s Capital as contemplated by Section 1.4(c). If Buyer disagrees with such calculation of Seller’s Capital, then Seller and Buyer shall attempt to resolve any such disagreement through good faith negotiations. If Seller and Buyer cannot resolve any such disagreement within ten (10) business days after Buyer has informed Seller of such disagreement, then an independent accounting firm mutually agreed to by Seller and Buyer shall resolve any such disagreement consistent with the terms of this Agreement, which resolution, in the absence of any mathematical error, shall be final and binding upon Seller and Buyer.

(e)All shares of Seller Common Stock that are owned immediately prior to the Effective Time by Seller or Buyer (other than shares of Seller Common Stock held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties (any such shares, “Trust Account Common Shares”) and other than shares of Seller Common Stock held, directly or indirectly, by Seller or Buyer in respect of a debt previously contracted (any such shares, “DPC Common Shares”) shall be cancelled and shall cease to exist and no stock of Buyer or other consideration shall be delivered in exchange therefor (any such shares, the “Cancelled Shares”).

(f)If, between the date of this Agreement and the Effective Time, the outstanding shares of Buyer Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization,

reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, and such change would have an economic effect on the value of the stock portion of the Merger Consideration, then an appropriate and proportionate adjustment shall be made to the Per Share Stock Consideration to provide the holders of Seller Common Stock converted into Merger Consideration the same economic effect as contemplated by this Agreement with respect to the stock portion of the Merger Consideration prior to such event; provided, however, that nothing in this Section 1.4(f) shall be construed to permit Buyer to take any action with respect to its securities that is prohibited by the terms of this Agreement.

(g)Holders of shares of Seller Common Stock who have not voted in favor of the Merger and otherwise complied with the requirements of Section 351.455 of the GBCLM will be entitled to exercise such rights with respect to the shares as to which rights have been perfected (“Dissenting Shares”), to the extent available under the GBCLM. Dissenting Shares shall not be converted into the right to receive the Merger Consideration but shall only be entitled to receive such consideration as will be determined under the GBCLM. Each share of Seller Common Stock that is outstanding immediately prior to the Effective Time and with respect to which dissenters rights under the GBCLM may be, but have not yet been perfected will, if and when such dissenters rights can no longer be legally perfected or exercised under the GBCLM, be converted into a right to receive the Merger Consideration, and will no longer be a Dissenting Share. Prior to the Closing Date, Seller shall from time to time give prompt notice to Buyer of any notifications, demands, attempted withdrawals of such demands and any other instruments served or delivered pursuant to the GBCLM by or to Seller for appraisal or determination of the fair value of shares. Buyer shall have a right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, Seller shall not, except with the prior written consent of Buyer, which consent shall not be unreasonably withheld, make any payment with respect to, settle, or offer to settle, any such demands.

1.6Directors and Officers. The directors and officers of Merger Sub immediately prior to the Effective Time shall be the directors and officers of the Surviving Company and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

1.7Tax Consequences. It is intended that the Mergers, taken together, shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a “plan of reorganization” for the purposes of Sections 354, 356, and 361 of the Code.

1.8The Second Step Merger. On the Closing Date and as soon as reasonably practicable following the Effective Time, in accordance with the GBCLM, Buyer shall cause the Surviving Company to be merged with and into Buyer in the Second Step Merger, with Buyer surviving the Second Step Merger and continuing its existence under the laws of the State of Missouri, and the separate corporate existence of the Surviving Company ceasing as of the Second Effective Time (as defined below). In furtherance of the foregoing, Buyer shall cause to be filed with the Missouri Secretary of State, in accordance with the GBCLM, articles of merger (“Second Articles of Merger”) relating to the Second Step Merger. The Second Step Merger shall become effective as of the date and time specified in the Second Articles of Merger (such date and time, the “Second Effective Time”). At and after the Second Effective Time, the Second Step Merger shall have the effects set forth in the applicable provisions of the GBCLM.

1.9The Bank Merger. At such time following the Second Step Merger as Buyer may determine in its sole discretion, Buyer intends to merge CB with and into Southern Bank in accordance with the provisions of applicable state and federal banking laws and regulations and Southern Bank shall be the resulting institution or surviving bank (the “Surviving Bank”). The Bank Merger shall have the effects as set forth under applicable state and federal banking laws and regulations and the boards of directors of the Parties shall approve, and shall cause the boards of directors of CB and Southern Bank, respectively, to approve, a separate combination agreement/plan of merger (the “Bank Plan of Merger”) in substantially the form attached hereto as Exhibit D, and cause the Bank Plan of Merger to be executed and delivered as soon as practicable following the date of execution of this Agreement. In addition, Seller shall cause CB, and Buyer shall cause Southern Bank, to execute and file in accordance with applicable state and federal banking laws and regulations such articles of merger or combination, corporate resolutions, and/or other documents and certificates as are necessary to make the Bank Merger effective (the “Bank Merger Certificates”).

1.10Change in Structure. Buyer may at any time change the method of effecting the Mergers and/or the Bank Merger; provided, however, that no such change or amendment shall (i) alter or change the amount or kind of the Merger Consideration to be received by the shareholders of Seller, (ii) adversely affect the tax consequences of the Merger to the shareholders of Seller or the tax treatment of either party pursuant to this Agreement or (iii) impede or materially delay consummation of the transactions contemplated by this Agreement.

1.11 Election Procedures. Each holder of record of shares of Seller Common Stock to be converted into the right to receive the Cash Consideration and/or the Stock Consideration in accordance with, and subject to, Sections 1.4 and 1.11 (a “Holder”) shall have the right, subject to the limitations set forth in this Article I, to submit an election in accordance with the following procedures:

(a)Each Holder may specify in a request made in accordance with the provisions of this Section 1.11 (an “Election”) (i) the number of shares of Seller Common Stock owned by such Holder with respect to which such Holder desires to make a Stock Election and (ii) the number of shares of Seller Common Stock owned by such Holder with respect to which such Holder desires to make a Cash Election. A share in respect of which the Holder has validly elected to make a Stock Election is referred to as a “Stock Election Share” and a share in respect of which the Holder has validly elected to make a Cash Election is referred to as a “Cash Election Share.”

(b)Buyer shall prepare a form reasonably acceptable to Seller, including appropriate and customary transmittal materials in such form as prepared by Buyer and reasonably acceptable to Seller (the “Form of Election”), so as to permit Holders to exercise their right to make an Election.

(c)Buyer shall initially make available and mail the Form of Election not less than twenty (20) business days prior to the anticipated Election Deadline to Holders of record as of the voting record date for the Seller Shareholder Meeting. The time period between such mailing date and the Election Deadline is referred to herein as the “Election Period”.

(d)Any Election shall have been made properly only if the Exchange Agent shall have received, during the Election Period, a Form of Election properly completed and signed by the Holder. It being understood and agreed by the Parties that the Form of Election may include a Letter of Transmittal (as defined at Section 2.3 hereof), which will require the delivery of Certificates to make a valid Election. As used herein, unless otherwise agreed in advance by the parties, “Election Deadline” means 5:00 p.m. local time (in the city in which the principal office of the Exchange Agent is located) on the date which the parties shall agree is as near as practicable to three (3) business days preceding the Closing Date. The Parties shall cooperate to issue a press release reasonably satisfactory to each of them announcing the date of the

Election Deadline not more than fifteen (15) business days before, and at least five (5) business days prior to, the Election Deadline.

(e)Any Holder may, at any time during the Election Period, change or revoke his or her Election by written notice to the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed revised Form of Election. If any Election is not properly made with respect to any shares of Seller Common Stock (none of Buyer, Seller nor the Exchange Agent being under any duty to notify any Holder of any such defect), such Election shall be deemed to be not in effect, and the shares of Seller Common Stock covered by such Election shall, for purposes hereof, be deemed to be Non-Election Shares, unless a proper Election is thereafter timely made.

(f)Any Holder may, at any time during the Election Period, revoke his or her Election by written notice received by the Exchange Agent prior to the Election Deadline or by withdrawal prior to the Election Deadline of his or her Certificates, or of the guarantee of delivery of such Certificates, previously deposited with the Exchange Agent, in which case the shares covered thereby shall, for purposes hereof, be deemed to be Non-Election Shares, unless a proper Election is thereafter timely made. All Elections shall be automatically deemed revoked upon receipt by the Exchange Agent of written notification from the parties that this Agreement has been terminated in accordance with the terms hereof.

(g)Subject to the terms of this Agreement and the Form of Election, Buyer, in the exercise of its reasonable, good faith discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement, governing (i) the validity of the Forms of Election and compliance by any Holder with the Election procedures set forth herein, (ii) the method of issuance and delivery of certificates representing the whole number of shares of Buyer Common Stock into which shares of Seller Common Stock are converted to Stock Consideration in the Merger and (iii) the method of payment of cash for shares of Seller Common Stock converted into the right to receive the Cash Consideration and cash in lieu of fractional shares of Buyer Common Stock.

1.12 Proration. Within five (5) business days after the Election Deadline, unless the Effective Time has not yet occurred, in which case as soon thereafter as practicable, Buyer shall cause the Exchange Agent to effect the allocation among the holders of shares of Seller Common Stock of rights to receive Buyer Common Stock and/or cash in the Merger in accordance with the Elections follows:

(a)Excess Cash Election. If the aggregate cash amount that would be paid upon the conversion in the Merger of the Cash Election Shares and the Dissenting Shares is greater than the Total Cash Amount (as defined in Section 1.12(a)(iii) below), then:

(i)all Stock Election Shares and Non-Election Shares shall be converted into the right to receive the Stock Consideration;

(ii)all Dissenting Shares shall be deemed, for the purposes of this Section 1.12(a)(ii), to be converted into the right to receive the Cash Consideration;

(iii)the Exchange Agent shall then select from among the Cash Election Shares, by a pro rata selection process, a sufficient number of shares of Seller Common Stock (“Stock Designated Shares”) such that the aggregate cash amount that will be paid in the Merger equals as closely as practicable twenty five percent (25%) of the Merger Consideration (the “Total Cash Amount”), and all Stock Designated Shares shall be converted into the right to receive the Stock Consideration; and

(iv)the Cash Election Shares that are not Stock Designated Shares will be converted into the right to receive the Cash Consideration.

(b)Excess Stock Election. If the aggregate cash amount that would be paid upon conversion in the Merger of the Cash Election Shares and Dissenting Shares is less than the Total Cash Amount, then:

(i)all Cash Election Shares and Non-Election Shares shall be converted into the right to receive the Cash Consideration;

(ii)all Dissenting Shares shall be deemed, for the purposes of this Section 1.12(b)(ii), to be converted into the right to receive the Cash Consideration;

(iii)the Exchange Agent shall then select from among the Stock Election Shares, by a pro rata selection process, a sufficient number of shares of Seller Common Stock (“Cash Designated Shares”) such that the aggregate cash amount that will be paid in the Merger equals as closely as practicable the Total Cash Amount, and all Cash Designated Shares shall be converted into the right to receive the Cash Consideration; and

(iv)the Stock Election Shares and the Non-Election Shares that are not Cash Designated Shares shall be converted into the right to receive the Per Share Stock Consideration.

(c)Proportionate Election. If the aggregate cash amount that would be paid upon conversion in the Merger of the Cash Election Shares and Dissenting Shares is equal or nearly equal (as determined by the Exchange Agent) to the Total Cash Amount, then subparagraphs (a) and (b) above shall not apply, and:

(i)all Dissenting Shares shall be converted in accordance with Section 1.4(g);

(ii)the Exchange Agent shall then select from among the Cash Election Shares, by a pro rata selection process, a sufficient number of Stock Designated Shares such that the aggregate cash amount that will be paid in the Merger equals as closely as practicable the Total Cash Amount, and all Stock Designated Shares shall be converted into the right to receive the Stock Consideration; and

(iii)the Cash Election Shares that are not Stock Designated Shares will be converted into the right to receive the Cash Consideration.

Article II

DELIVERY OF MERGER CONSIDERATION

2.1Exchange Agent. Prior to the Effective Time, Buyer shall appoint an unrelated bank or trust company reasonably acceptable to Seller, or Buyer’s transfer agent, pursuant to an agreement (the “Exchange Agent Agreement”) to act as exchange agent (the “Exchange Agent”) hereunder.

2.2Deposit of Merger Consideration. At or prior to the Effective Time, Buyer shall (i) deposit with the Exchange Agent, or authorize the Exchange Agent to issue, an aggregate number of shares of Buyer Common Stock equal to the stock portion of the Merger Consideration and (ii) deposit, or cause to be deposited, with the Exchange Agent an amount in cash sufficient to pay the cash portion of the Merger Consideration plus, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 2.3(f), plus the amount of cash necessary to fund the cancellation of Options pursuant to Section 1.4(b) (together, the “Exchange Fund”) and Buyer shall instruct the Exchange Agent to timely deliver the Merger Consideration.

2.3Delivery of Merger Consideration.

(a)As soon as reasonably practicable after the Effective Time (and in any event within five (5) days thereafter), and subject to the receipt by the Exchange Agent of a list of Seller’s shareholders in a format that is reasonably acceptable to the Exchange Agent, the Exchange Agent shall mail to each holder of a Certificate, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or an affidavit of loss in lieu thereof) to the Exchange Agent) in such form and substance as shall be prescribed by the Exchange Agent Agreement (the “Letter of Transmittal”) and (ii) instructions for use in surrendering each Certificate in exchange for the Merger Consideration, any cash in lieu of a fractional share of Buyer Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to Section 2.3(c).

(b)Subject to the Election Procedures in Section 1.11 hereof, as soon as reasonably practicable after surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, such holder of Seller Common Stock will be entitled to receive the Merger Consideration, any cash in lieu of a fractional share of Buyer Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such holder is entitled pursuant to Section 2.3(c), in respect of the shares of Seller Common Stock represented by such holder’s Certificate or Certificates. Until so surrendered, each Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration, any cash in lieu of a fractional share of Buyer Common Stock to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with, and any dividends or distributions to which such holder is entitled pursuant to, this Article II.

(c)No dividends or other distributions with respect to Buyer Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Buyer Common Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this Article II. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive, without interest, and in addition to the other amounts set forth herein, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of Buyer Common Stock represented by such Certificate and not paid and (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to whole shares of Buyer Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the Buyer Common Stock issuable with respect to such Certificate.

(d)In the event of a transfer of ownership of a Certificate representing Seller Common Stock prior to the Effective Time that is not registered in the stock transfer records of Seller, the Merger Consideration, any cash in lieu of a fractional share of Buyer Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such holder is entitled, shall be issued or paid in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such Seller Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes (as defined in Section 3.18) required by reason of the payment or issuance to a person other than the registered holder of the Certificate or establish to the satisfaction of Buyer that the Tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the earlier of (x) six months after the Effective Time and (y) the expiration or termination of the Exchange Agent Agreement, Buyer) shall be entitled to deduct and withhold from the cash portion of the Merger Consideration and any cash in lieu of a fractional share of Buyer Common Stock otherwise payable pursuant

to this Agreement to any holder of Seller Common Stock such amounts as the Exchange Agent or Buyer, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign tax law, with respect to the making of such payment; provided, however, that prior to making any such deduction or withholding, Buyer shall instruct the Exchange Agent to use commercially reasonable best efforts to solicit from such holder of Seller Common Stock an Internal Revenue Service (“IRS”) Form W-9 or other applicable tax form (which may be included in the Letter of Transmittal) within a reasonable amount of time in order to provide the opportunity for such Holder to provide such forms to avoid or reduce such withholding amounts. To the extent amounts are so withheld by the Exchange Agent or Buyer, as the case may be, and timely paid over to the appropriate Governmental Entity (as defined in Section 3.6), such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Seller Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or Buyer, as the case may be.

(e)After the Effective Time, there shall be no transfers on the stock transfer books of Seller of the shares of Seller Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of Seller Common Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration, any cash in lieu of fractional shares of Buyer Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such holder is entitled, in accordance with the procedures set forth in this Article II.

(f)Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of Buyer Common Stock shall be issued upon the surrender of Certificates for exchange, no dividend or distribution with respect to Buyer Common Stock shall be payable on or with respect to any fractional share, and such fractional share interest shall not entitle the owner thereof to vote or to any other rights of a shareholder of Buyer. In lieu of the issuance of any such fractional share, Buyer shall pay to each former shareholder of Seller who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the Closing Price by (ii) the fraction of a share (after taking into account all shares of Seller Common Stock held by such holder at the Effective Time and rounded to the nearest one ten thousandth when expressed in decimal form) of Buyer Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 1.4(b).

(g)Any portion of the Exchange Fund that remains unclaimed by the former shareholders of Seller at the expiration of six months after the Effective Time shall be paid to Buyer. In such event, any former shareholders of Seller who have not theretofore complied with this Article II shall thereafter look only to Buyer with respect to the Merger Consideration, any cash in lieu of any fractional share interest and any unpaid dividends and distributions on the Buyer Common Stock deliverable in respect of the shares represented by a Certificate such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Buyer, Merger Sub, Seller, the Surviving Company, the Exchange Agent or any other person shall be liable to any former holder of shares of Seller Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(h)In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Buyer or the Exchange Agent, the posting by such person of a bond in such amount as Buyer or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration, any cash in lieu of any fractional share

interest and any dividends and distributions to which such person is entitled in respect thereof pursuant to this Agreement.

Article III

Except as disclosed in the disclosure schedule delivered by Seller to Buyer concurrently herewith (the “Seller Disclosure Schedule”) or as previously provided to Buyer (“Previously Disclosed”); provided, that (a) no such item is required to be set forth as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect, (b) the mere inclusion of an item in the Seller Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by Seller that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect (as defined in Section 3.1) on Seller and (c) any disclosures made with respect to a section of Article III shall be deemed to qualify (1) any other section of Article III specifically referenced or cross-referenced and (2) other sections of Article III to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure applies to such other sections, Seller hereby represents and warrants to Buyer as follows:

3.1 Organization and Standing. Seller is a corporation duly organized, validly existing and in good standing under the laws of the State of Missouri. Seller is duly qualified to do business and is in good standing in the states of the United States and any foreign jurisdictions where its ownership or leasing of property or assets or the conduct of its business requires it to be so qualified, except where the failure to be so qualified would not have a Material Adverse Effect on Seller. Seller is a registered bank holding company with the Federal Reserve Board. As used in this Agreement, the term “Material Adverse Effect” means, with respect to Buyer, Merger Sub, Seller or the Surviving Company, as the case may be, changes, developments, occurrences, or events having a material adverse effect on (i) the business, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in United States generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, or authoritative interpretations thereof, (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally, (D) public disclosure of the transactions contemplated hereby or actions or inactions expressly required by this Agreement or that are taken with the prior written consent of the other party in contemplation of the transactions contemplated hereby, (E) a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections, but not, in either case, including the underlying causes thereof, or (F) earthquakes, hurricanes, tornados, floods, mudslides, fires or other disasters or acts of god or any other force majeure events beyond the reasonable control of such Party or its Subsidiaries, or (G) any declaration by an applicable Governmental Entity (as defined in Section 3.5 hereof) of any national or global epidemic, pandemic, or disease outbreak (including the COVID-19 virus), or the material worsening of such conditions threatened or existing as of the date of this Agreement; except, with respect to subclauses (A), (B), (C), (F) or (G) to the extent that the effects of such change are materially disproportionately adverse to the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries, taken as a whole, as compared to other companies in the industry (or geographic area with respect to any of the events in clause (F) above) in which such party and its Subsidiaries operate), or (ii) the ability of such party or its financial institution Subsidiary to timely

consummate the transactions contemplated hereby. As used in this Agreement, the word “Subsidiary” when used with respect to any party, means any corporation, partnership, limited liability company, bank or other organization, whether incorporated or unincorporated, which is consolidated with such party for financial reporting purposes. True and complete copies of the amended and restated articles of incorporation of Seller (the “Seller Articles”) and the bylaws of Seller (the “Seller Bylaws”), as in effect as of the date of this Agreement, have previously been made available by Seller to Buyer.

3.2 Capitalization. As of the date hereof, the authorized capital stock of Seller consists exclusively of 5,000,000 shares of common stock, $0.01 par value per share, of which as of the date hereof 2,561,600 shares are issued and 1,745,258 shares are voting and 601,657 shares of non-voting are outstanding. Except as set forth in Section 3.2 of the Seller Disclosure Schedule, Seller does not have and is not bound by any outstanding subscriptions, options, warrants, calls, commitments or agreements of any character calling for the purchase or issuance of any shares of Seller Common Stock or any other equity securities of Seller or any of its Subsidiaries or any securities representing the right to purchase or otherwise receive any shares of Seller Common Stock or other equity securities of Seller or any of its Subsidiaries. The outstanding shares of Seller Common Stock are duly authorized and validly issued and outstanding, fully paid and nonassessable, and, except as Previously Disclosed, subject to no preemptive rights (and were not, and will not be, issued in violation of any preemptive rights). There are no bonds, debentures, notes or other indebtedness that have the right to vote on any matters on which shareholders of Seller may vote. There are no obligations of Seller or CB pursuant to which Seller or CB is or could be required pursuant to the terms thereof to register any of its securities under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”). Except as set forth in Section 3.2 of the Seller Disclosure Schedule no trust preferred or subordinated debt securities of Seller or CB are issued or outstanding. Except as set forth in Section 3.2 of the Seller Disclosure Schedule, there are no outstanding subscriptions, options, warrants, puts, calls, rights, exchangeable or convertible securities or other commitments or agreements obligating Seller to issue, transfer, sell, purchase, redeem or otherwise acquire, any shares of Seller Common Stock or any other of its securities.

3.9 Regulatory Matters.

(a)Neither Seller nor any of its Subsidiaries or properties is a party to or is subject to any order, decree, agreement, memorandum of understanding or similar arrangement with, or a commitment letter or similar submission to, or extraordinary supervisory letter from, any federal or state governmental agency or authority charged with the supervision or regulation of financial institutions (or their holding companies) or issuers of securities or engaged in the insurance of deposits (including, without limitation,

(a)is in material compliance with all applicable federal, state, local and foreign statutes, laws, regulations, ordinances, rules, judgments, orders or decrees applicable thereto or to the employees conducting such businesses, except where the failure to be so in compliance would not reasonably be expected to have a Material Adverse Effect on Seller;

Except

(b)Each Seller Compensation and Benefit Plan has been operated and administered in all material respects in accordance with its terms and with applicable law, including, but not limited to, ERISA, the Code or any regulations or rules promulgated thereunder, and all filings, disclosures and notices required by ERISA, the Code and any other applicable law have been timely made. Each Seller Compensation and Benefit Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA (a “Seller Pension Plan”) and which is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter (including a determination that the related trust under such Seller Compensation and Benefit Plan is exempt from tax under Section 501(a) of the Code) from the IRS or the Seller Compensation and Benefit Plan uses a prototype or volume submitter plan that is the subject of an IRS opinion or advisory letter, and Seller is not aware of any circumstances which could adversely affect such qualification or which are likely to result in the revocation of any existing favorable determination letter or in not receiving a favorable determination letter. There is no pending or, to the knowledge of Seller, threatened legal action, suit or claim relating to the Seller Compensation and Benefit Plans other than routine claims for benefits. Neither Seller nor any of its Subsidiaries has engaged in a transaction, or omitted to take any action, with respect to any Seller Compensation and Benefit Plan that would reasonably be expected to subject Seller or any of its Subsidiaries to a material tax or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming for purposes of Section 4975 of the Code that the taxable period of any such transaction expired as of the date hereof.

(c)No liability (other than for payment of premiums to the PBGC which have been made or will be made on a timely basis) under Title IV of ERISA has been or is expected to be incurred by Seller or any of its Subsidiaries with respect to any ongoing, frozen or terminated “single-employer plan” within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or any single-employer plan of any entity (a “Seller ERISA Affiliate”) which is considered one employer with Seller under Section 4001(a)(14) of ERISA or Section 414(b) or (c) of the Code (a “Seller ERISA Affiliate Plan”). None of Seller, any of its Subsidiaries or any Seller ERISA Affiliate has contributed, or has been obligated to contribute, to (i) a multiemployer plan under Subtitle E of Title IV of ERISA at any time since December 31, 2016, or (ii) except as set forth in Section 3.13(c)(ii) of the Seller Disclosure Schedule, a multiple employer plan covered by Section 413(c) of the Code at any time since December 31, 2016. If the Seller or any of its Subsidiaries or any Seller ERISA Affiliate has participated in a multiple employer plan at any time since December 31, 2016, such plan and each participating employer in such plan has complied with all requirements of the Code and ERISA applicable to such plan and each participating employer in such plan at all times since December 31, 2016, and the Seller and its Subsidiaries may withdraw from such plan without incurring any liability associated with such withdrawal. No notice of a “reportable event,” within the meaning of Section 4043 of ERISA for which the 30-day reporting requirement has not been waived, has been required to be filed for any Seller Compensation and Benefit Plan or by any Seller ERISA Affiliate Plan within the 12-month period ending on the date hereof, and no such notice will be required to be filed as a result of the transactions contemplated by this Agreement. The PBGC has not instituted proceedings to terminate any Seller Pension Plan or Seller ERISA Affiliate Plan and, to Seller’s knowledge, no condition exists that presents a material risk that such proceedings will be instituted. To the knowledge of Seller, there is no pending investigation or enforcement action by the PBGC, the DOL or the IRS or any other governmental agency with respect to any Seller Compensation and Benefit Plan. Under each Seller Pension Plan and Seller ERISA Affiliate Plan, as of the date of the most recent actuarial valuation performed prior to the date of this Agreement, the actuarially determined present value of all “benefit liabilities,” within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in such actuarial valuation of such Seller Pension Plan or Seller ERISA Affiliate Plan), did not exceed the then current value of the assets of such Seller Pension Plan or Seller ERISA

Affiliate Plan and since such date there has been neither an adverse change in the financial condition of such Seller Pension Plan or Seller ERISA Affiliate Plan nor any amendment or other change to such Seller Pension Plan or Seller ERISA Affiliate Plan that would increase the amount of benefits thereunder which reasonably could be expected to change such result.

(d)All contributions required to be made under the terms of any Seller Compensation and Benefit Plan or Seller ERISA Affiliate Plan or any employee benefit arrangements under any collective bargaining agreement to which Seller or any of its Subsidiaries is a party have been timely made or have been reflected on Seller’s Financial Statements. Neither any Seller Pension Plan nor any Seller ERISA Affiliate Plan has an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA and all required payments to the PBGC with respect to each Seller Pension Plan or Seller ERISA Affiliate Plan have been made on or before their due dates. None of Seller, any of its Subsidiaries or any Seller ERISA Affiliate (x) has provided, or would reasonably be expected to be required to provide, security to any Seller Pension Plan or to any Seller ERISA Affiliate Plan pursuant to Section 401(a)(29) of the Code, and (y) has taken any action, or omitted to take any action, that has resulted, or would reasonably be expected to result, in the imposition of a lien under Section 412(n) of the Code or pursuant to ERISA.

(e)Neither Seller nor any of its Subsidiaries has any obligations to provide retiree health and life insurance or other retiree death benefits under any Seller Compensation and Benefit Plan, other than benefits mandated by Section 4980B of the Code, and each such Seller Compensation and Benefit Plan may be amended or terminated without incurring liability thereunder, and there has been no communication to Seller Employees by Seller or any of its Subsidiaries that would reasonably be expected to promise or guarantee such Seller Employees retiree health or life insurance or other retiree death benefits on a permanent basis.

(f)Seller and its Subsidiaries do not maintain any Seller Compensation and Benefit Plans covering foreign Seller Employees.

(g)With respect to each Seller Compensation and Benefit Plan, if applicable, Seller has provided or made available to Buyer, true and complete copies of: (i) existing Seller Compensation and Benefit Plan documents and amendments thereto; (ii) all trust instruments and insurance contracts; (iii) the two most recent Forms 5500 filed with the IRS; (iv) the most recent actuarial report and financial statement; (v) the most recent summary plan description; (vi) the most recent determination or opinion letter issued by the IRS; (vii) any Form 5310 or Form 5330 filed with the IRS; and (viii) the most recent nondiscrimination tests performed under ERISA and the Code (including 401(k) and 401(m) tests).

(h)Except as set forth in Section 3.13(h) of the Seller Disclosure Schedule, the consummation of the transactions contemplated by this Agreement would not, directly or indirectly (including, without limitation, as a result of any termination of employment prior to or following the Effective Time) (i) entitle any Seller Employee, Seller Consultant or Seller Director to any payment (including severance pay or similar compensation) or any increase in compensation, (ii) result in the vesting or acceleration of any benefits under any Seller Compensation and Benefit Plan or (iii) result in any material increase in benefits payable under any Seller Compensation and Benefit Plan.

(i)Neither Seller nor any of its Subsidiaries maintains any compensation plans, programs or arrangements the payments under which would not reasonably be expected to be deductible as a result of the limitations under Section 162(m) of the Code and the regulations issued thereunder.

(j)As a result, directly or indirectly, of the transactions contemplated by this Agreement (including, without limitation, as a result of any termination of employment prior to or following

the Effective Time), neither Buyer nor Seller, nor any of their respective Subsidiaries will be obligated to make a payment to any Seller Employee that would be characterized as an “excess parachute payment” to an individual who is a “disqualified individual” (as such terms are defined in Section 280G of the Code), without regard to whether such payment is reasonable compensation for personal services performed or to be performed in the future.

(k)As of the Effective Time, except as Previously Disclosed, there are no supplemental employment retirement plans (SERPs) between Seller, any of its Subsidiaries and any of their employees.

(l)Neither Seller nor any of its Subsidiaries has made any agreement, taken any action, or omitted to take any action, with respect to or as part of any Seller Compensation and Benefit Plan that is an operational failure under Section 409A of the Code or that would reasonably be expected to subject Seller or any of its Subsidiaries to any obligation to report any amount or withhold any amount as includable in income and subject to tax, interest or any penalty by any service provider to Seller or any of its Subsidiaries under Section 409A of the Code or to pay any reimbursement or other payment to any service provider, as defined under Section 409A of the Code, respecting any such tax, interest or penalty under Section 409A of the Code. As a result, directly or indirectly, of the transactions contemplated by this Agreement (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), neither Seller nor any of its Subsidiaries will be obligated to report any amount or withhold any amount as includable in income and subject to tax, interest or any penalty by any service provider (as defined under Section 409A of the Code) to Seller or any of its Subsidiaries under Section 409A of the Code or to pay any reimbursement or other payment to any service provider (as defined under Section 409A of the Code) respecting any such Tax, interest or penalty under Section 409A of the Code and no provision of any of the Seller Compensation and Benefit Plans, or any actions taken or omitted thereunder, violate Section 409A of the Code.

3.14Labor Matters. Neither Seller nor any of its Subsidiaries is a party to or is bound by any collective bargaining agreement, contract or other agreement or understanding with a labor union or labor organization, nor is Seller or any of its Subsidiaries the subject of a proceeding asserting that it or any such Subsidiary has committed an unfair labor practice (within the meaning of the National Labor Relations Act) or seeking to compel Seller or any such Subsidiary to bargain with any labor organization as to wages or conditions of employment, nor is there any strike or other labor dispute involving it or any of its Subsidiaries pending or, to Seller’s knowledge, threatened, nor is Seller aware of any activity involving its or any of its Subsidiaries’ employees seeking to certify a collective bargaining unit or engaging in other organizational activity.

(h) Neither Buyer nor any of its Subsidiaries has incurred any debt, liability or obligation of any nature whatsoever (whether accrued, contingent, absolute or otherwise and whether due or to become due) that would be required to be set forth on a balance sheet prepared in accordance with GAAP other than liabilities reflected on or reserved against in the most recent audited balance sheet included in Buyer's SEC Documents, except for (i) liabilities incurred in the ordinary course of business consistent with past practice that, either alone or when combined with all similar liabilities, have not had, and would not reasonably be expected to have, a Material Adverse Effect on Buyer, (ii) executory obligations under contracts; and (iii) liabilities incurred for legal, accounting, financial advisory fees and out-of-pocket expenses in connection with the transactions contemplated by this Agreement.

To the knowledge of Buyer, there is no fact or circumstance or set of facts and circumstances that would cause Southern Bank’s CRA rating to fall below “satisfactory.”

(b)Southern Bank is "well-capitalized" (as that term is defined in 12 C.F.R. § 225.2(r)) and "well managed" (as that term is defined is 12 C.F.R. § 225.2(s)).

Each of Buyer and its Subsidiaries:

(a)is in material compliance with all applicable federal, state, local and foreign statutes, laws, regulations, ordinances, rules, judgments, orders or decrees applicable thereto or to the employees conducting such businesses, except where the failure to be so in compliance could not reasonably be expected to have a Material Adverse Effect on Buyer;

(b)has all permits, licenses, authorizations, orders and approvals of, and has made all filings, applications and registrations with, all Governmental Entities that are required in order to permit them to own or lease their properties and to conduct their businesses as presently conducted, except where the failure to obtain such permit, license, authorization, order or approval or make such filing, application or registration could not reasonably be expected to have a Material Adverse Effect on Buyer and its Subsidiaries; all such permits, licenses, certificates of authority, orders and approvals are in full force and effect and, to Buyer’s knowledge, no suspension or cancellation of any of them is threatened;

(c)has received no written notification from any Governmental Entity (A) asserting that Buyer or any of its Subsidiaries is not in compliance with any of the statutes, regulations, or ordinances which such Governmental Entity enforces or (B) threatening to revoke any license, franchise, permit, or governmental authorization (nor, to Buyer’s knowledge, do any grounds for any of the foregoing exist);

(d)is in material compliance with the privacy provisions of the Gramm-Leach-Bliley Act, and all other applicable laws relating to consumer privacy; and

(e)is in compliance with its articles of incorporation and bylaws or equivalent documents.

4.11Employee Benefit Plans.

(a)Buyer has Previously Disclosed a complete and accurate list of all existing bonus, incentive, deferred compensation, pension, retirement, profit-sharing, thrift, savings, employee stock ownership, stock bonus, stock purchase, restricted stock, stock option, severance, welfare and fringe benefit plans, employment or severance agreements and all similar practices, policies and arrangements in which any current or former employee (the “Buyer Employees”), current or former consultant (the “Buyer Consultants”) or current or former director (the “Buyer Directors”) of Buyer or any of its Subsidiaries participates or to which any Buyer Employees, Buyer Consultants or Buyer Directors are a party (the “Buyer Compensation and Benefit Plans”).

(b)Each Buyer Compensation and Benefit Plan has been operated and administered in all material respects in accordance with its terms and with applicable law, including, but not limited to, ERISA, the Code, the Securities Act, the Exchange Act or any regulations or rules promulgated thereunder, and all filings, disclosures and notices required by ERISA, the Code, the Securities Act, the Exchange Act and any other applicable law have been timely made. Each Buyer Compensation and Benefit Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA (a “Buyer Pension Plan”) and which is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter (including a determination that the related trust under such Buyer Compensation and Benefit Plan is exempt from tax under Section 501(a) of the Code) from the IRS or the Buyer Compensation and Benefit Plan uses a prototype or volume submitter plan that is the subject of an IRS opinion or advisory letter, and Buyer is not aware of any circumstances which could adversely affect such qualification or which are likely to result in the revocation of any existing favorable determination letter or in not receiving a favorable determination letter. There is no pending or, to the knowledge of Buyer, threatened legal action, suit or claim relating to the Buyer Compensation and Benefit Plans other than routine claims for benefits. Neither Buyer nor any of its Subsidiaries has engaged in a transaction, or omitted to take any action, with respect to any Buyer Compensation and Benefit Plan that would reasonably be expected to subject Buyer or any of its Subsidiaries to a tax or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming for purposes of Section 4975 of the Code that the taxable period of any such transaction expired as of the date hereof.

(c)No liability (other than for payment of premiums to the PBGC which have been made or will be made on a timely basis) under Title IV of ERISA has been or is expected to be incurred by Buyer or any of its Subsidiaries with respect to any ongoing, frozen or terminated “single-employer plan” within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or any single-employer plan of any entity (a “Buyer ERISA Affiliate”) which is considered one employer with Buyer under Section 4001(a)(14) of ERISA or Section 414(b) or (c) of the Code (a “Buyer ERISA Affiliate Plan”). None of Buyer, any of its Subsidiaries or any Buyer ERISA Affiliate has contributed, or has been obligated to contribute, to a multiemployer plan under Subtitle E of Title IV of ERISA at any time since December 31, 2016. No notice of a “reportable event,” within the meaning of Section 4043 of ERISA for which the 30-day reporting requirement has not been waived, has been required to be filed for any Buyer Compensation and Benefit Plan or by any Buyer ERISA Affiliate Plan within the 12-month period ending on the date hereof, and no such notice will be required to be filed as a result of the transactions contemplated by this Agreement. The PBGC has not instituted proceedings to terminate any Buyer Pension Plan or Buyer ERISA Affiliate Plan and, to Buyer’s knowledge, no condition exists that presents a material risk that such

proceedings will be instituted. To the knowledge of Buyer, there is no pending investigation or enforcement action by the PBGC, DOL or IRS or any other governmental agency with respect to any Buyer Compensation and Benefit Plan. Under each Buyer Pension Plan and Buyer ERISA Affiliate Plan, as of the date of the most recent actuarial valuation performed prior to the date of this Agreement, the actuarially determined present value of all “benefit liabilities,” within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in such actuarial valuation of such Buyer Pension Plan or Buyer ERISA Affiliate Plan), did not exceed the then current value of the assets of such Buyer Pension Plan or Buyer ERISA Affiliate Plan and since such date there has been neither an adverse change in the financial condition of such Buyer Pension Plan or Buyer ERISA Affiliate Plan nor any amendment or other change to such Buyer Pension Plan or Buyer ERISA Affiliate Plan that would increase the amount of benefits thereunder which reasonably could be expected to change such result.

(d)All contributions required to be made under the terms of any Buyer Compensation and Benefit Plan or Buyer ERISA Affiliate Plan or any employee benefit arrangements under any collective bargaining agreement to which Buyer or any of its Subsidiaries is a party have been timely made or have been reflected on Buyer’s financial statements. Neither any Buyer Pension Plan nor any Buyer ERISA Affiliate Plan has an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA and all required payments to the PBGC with respect to each Buyer Pension Plan or Buyer ERISA Affiliate Plan have been made on or before their due dates. None of Buyer, any of its Subsidiaries or any Buyer ERISA Affiliate (x) has provided, or would reasonably be expected to be required to provide, security to any Buyer Pension Plan or to any Buyer ERISA Affiliate Plan pursuant to Section 401(a)(29) of the Code, and (y) has taken any action, or omitted to take any action, that has resulted, or would reasonably be expected to result, in the imposition of a lien under Section 412(n) of the Code or pursuant to ERISA.

(e)Neither Buyer nor any of its Subsidiaries has any obligations to provide retiree health and life insurance or other retiree death benefits under any Buyer Compensation and Benefit Plan, other than benefits mandated by Section 4980B of the Code, and each such Buyer Compensation and Benefit Plan may be amended or terminated without incurring liability thereunder and there has been no communication to Employees by Buyer or any of its Subsidiaries that would reasonably be expected to promise or guarantee such Employees retiree health or life insurance or other retiree death benefits on a permanent basis.

(f)Buyer and its Subsidiaries do not maintain any Buyer Compensation and Benefit Plans covering foreign Employees.

(g)The consummation of the transactions contemplated by this Agreement would not, directly or indirectly (including, without limitation, as a result of any termination of employment prior to or following the Effective Time) (A) entitle any Buyer Employee, Buyer Consultant or Buyer Director to any payment (including severance pay or similar compensation) or any increase in compensation, (B) result in the vesting or acceleration of any benefits under any Buyer Compensation and Benefit Plan or (C) result in any material increase in benefits payable under any Buyer Compensation and Benefit Plan.

(h)Neither Buyer nor any of its Subsidiaries has made any agreement, taken any action, or omitted to take any action, with respect to or as part of any Buyer Compensation and Benefit Plan that is an operational failure under Section 409A of the Code or that would reasonably be expected to subject Buyer or any of its Subsidiaries to any obligation to report any amount or withhold any amount as includable in income and subject to tax, interest or any penalty by any service provider to Buyer or any of its Subsidiaries under Section 409A of the Code or to pay any reimbursement or other payment to any service provider, as defined under Section 409A of the Code, respecting any such tax, interest or penalty under Section 409A of the Code.

4.13Environmental Matters. To Buyer’s knowledge, neither the conduct nor operation of Buyer or its Subsidiaries nor any condition of any property presently or previously owned, leased or operated by any of them (including, without limitation, in a fiduciary or agency capacity), or on which any of them holds a Lien, violates or violated Environmental Laws and to Buyer’s knowledge no condition has existed or event has occurred with respect to any of them or any such property that, with notice or the passage of time, or both, is reasonably likely to result in liability under Environmental Laws. Neither Buyer nor any of its Subsidiaries has received any written notice from any person or entity that Buyer or its Subsidiaries or the operation or condition of any property previously owned, leased, operated or held as collateral or in a fiduciary capacity by any of them are or were in violation of or otherwise are alleged to have liability under any Environmental Law, including, but not limited to, responsibility (or potential responsibility) for the cleanup or other remediation of any pollutants, contaminants, or hazardous or toxic wastes, substances or materials at, on, beneath or originating from any such property.

Neither Buyer nor any of its Subsidiaries has any liability with respect to income, franchise or similar Taxes that accrued on or before June 30, 2021, in excess of the amounts accrued with respect thereto that are reflected in the financial statements of Buyer as of June 30, 2021. As of the date hereof, neither Buyer nor any of its Subsidiaries has any knowledge of any conditions that exist that might prevent or impede the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

4.15Risk Management Instruments. Neither Buyer nor any of its Subsidiaries are parties to any interest rate swaps, caps, floors, option agreements, futures and forward contracts and other similar risk management arrangements, whether entered into for Buyer’s own account, or for the account of one or more of Buyer’s Subsidiaries or their customers.

4.16Books and Records.

The real estate owned, if any, reflected on Buyer’s consolidated balance sheet as of June 30, 2022 included in Buyer’s SEC Documents is, and will be in the case of subsequent consolidated financial statements of Buyer, carried at the lower of cost or fair value, less estimated costs to sell, as required by GAAP.

Prior to filing the Form S-4, Buyer shall provide Seller a reasonable opportunity to review and comment on the Form S-4 and the Proxy Statement. Each of Buyer and Seller shall use its commercially reasonable best efforts to respond as promptly as practicable to any written or oral comments from the SEC or its staff with respect to the Form S-4 or any related matters. Each of Seller and Buyer shall use its commercially reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing and to maintain such

effectiveness for as long as necessary to consummate the Merger and the other transactions contemplated by this Agreement unless this Agreement is terminated pursuant to Section 8.1. Upon the Form S-4 being declared effective, Seller shall thereafter mail or deliver the Proxy Statement to the holders of Seller Common Stock and Buyer shall mail or deliver the Proxy Statement to the holders of Buyer Common Stock. Buyer shall also use its commercially reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions contemplated by this Agreement, and Seller shall furnish all information concerning Seller and the holders of Seller Common Stock as may be reasonably requested in connection with any such action. If at any time prior to the Effective Time any event occurs or information relating to Seller or Buyer, or any of their respective affiliates, directors or officers, should be discovered by Seller or Buyer that should be set forth in an amendment or supplement to either the Form S-4 or the Proxy Statement, so that either such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other party hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by applicable law, disseminated to the holders of Seller Common Stock.

(b)In addition to their obligations pursuant to Section 6.1(a), Seller and Buyer shall make all necessary filings with respect to the Merger and the other transactions contemplated by this Agreement under the Securities Act, the Exchange Act and applicable foreign or state securities or “Blue Sky” laws and regulations promulgated thereunder and provide each other with copies of any such filings.

No amendment or supplement to the Proxy Statement or the Form S-4 shall be filed without the approval of each of Seller and Buyer, which approval shall not be unreasonably withheld, delayed or conditioned. Prior to responding to any comments or requests for additional information from the SEC, each of Buyer and Seller shall cooperate and provide the other a reasonable opportunity to review and comment on such response. With respect to the issuance of any stop order or the suspension of the qualification of the Buyer Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, Buyer and Seller shall use their commercially reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated.

(c)Subject to the terms and conditions set forth in this Agreement, Buyer and Seller shall, and shall cause their respective Subsidiaries to, use commercially reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other party in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including (i) the satisfaction of the conditions precedent to the obligations of Seller (in the case of Buyer) or Buyer (in the case of Seller) to the Merger, (ii) the obtaining of all necessary consents or waivers from third parties, (iii) the obtaining of all waivers, consents, authorizations, permits, orders and approvals from, or any exemption by, any Governmental Entities, and (iv) the execution and delivery of any additional instruments necessary to consummate the Merger, the Bank Merger and to fully carry out the purposes of this Agreement. The Parties shall cooperate with each other and use their respective commercially reasonable best efforts to promptly prepare and file, and cause their respective Subsidiaries to prepare and file, all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties, Regulatory Authorities and other Governmental Entities that are necessary or advisable to consummate the transactions contemplated by this

Agreement (including the Merger and the Bank Merger), and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such third parties, Regulatory Authorities or other Governmental Entities. In furtherance (but not in limitation) of the foregoing, Buyer shall, and shall cause Southern Bank to, use commercially reasonable best efforts to file any required applications, notices or other filings with the Federal Reserve Board or the Division, if applicable, within sixty (60) days after the date hereof. Seller and Buyer shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the confidentiality of information, all the information relating to Seller or Buyer, as the case may be, and any of their respective Subsidiaries, that appear in any filing made with, or written materials submitted to, any third party, Regulatory Authority or other Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the Parties shall act reasonably and as promptly as practicable.

(e)Each of Buyer and Seller shall promptly advise the other upon receiving any communication from any Regulatory Authority or other Governmental Entity the consent or approval of which is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval may be materially delayed, or that any such approval may contain an Unduly Burdensome Condition (as defined in Section 7.1(e)).

their respective Subsidiaries shall be required to provide access to or to disclose information (i) relating to the transactions contemplated by this Agreement or an Acquisition Proposal (as defined in Section 6.7) except as set forth in Section 6.7(d), (ii) where such access or disclosure would violate or prejudice the rights of Buyer’s or Seller’s, as the case may be, customers, jeopardize the attorney-client privilege of the party in possession or control of such information or contravene any law, rule regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement or (iii) otherwise reasonably deemed by the Buyer or Seller board of directors to be confidential. The Parties will use commercially reasonable best efforts to make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(c)Subject to applicable law and regulations, during the period from the date hereof to the Effective Time, Seller shall, upon the reasonable request of Buyer, cause one or more of its designated officers to confer on a monthly basis (or more frequently if the Parties reasonably agree that it is necessary) with officers of Buyer regarding the financial condition, operations and business of Seller and its Subsidiaries and matters relating to the completion of the transactions contemplated by this Agreement.

Seller will also deliver to Buyer as soon as practicable all quarterly and annual financial statements of Seller and its Subsidiaries prepared with respect to periods ending on or after December 31, 2021; provided however, that the loan (or similar) committee materials provided to Buyer may exclude (i) any materials relating to the transactions contemplated by this Agreement or an Acquisition Proposal (as defined in Section 6.8), (ii) any materials if the disclosure of such materials to Buyer would or could reasonably be expected to violate or prejudice the rights of Seller’s customers, jeopardize the attorney-client privilege or result in a violation of applicable law, regulation or orders, decrees or determinations of a Governmental Entity or any binding agreement or any fiduciary duty, or (iii) any materials that are otherwise reasonably deemed by the Seller board of directors to be confidential. As soon as practicable after the end of each month, Seller will deliver to Buyer in electronic form (A) the monthly deposit and loan trial balances of CB, (B) the monthly analysis of CB’s investment portfolio, (C) monthly balance sheet and income statement of Seller and CB, and (D) to the extent available, an update of all of the information set forth in Section 3.28(a) of the Seller Disclosure Schedule for the then current period.

Between the date hereof and the earlier of the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, Merger Sub shall not, and Buyer shall not permit Merger Sub to, engage in any activity of any nature or incur any liabilities except as contemplated by or in furtherance of the transactions contemplated hereby.

Notwithstanding anything to the contrary herein, unless this Agreement has been terminated pursuant to Section 8.1 prior to the scheduled time of the Seller Shareholder Meeting, the Seller Shareholder Meeting shall be convened and this Agreement shall be submitted to the shareholders of Seller at the Seller Shareholder Meeting for the purpose of voting on the adoption of this Agreement and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve Seller of such obligation.

Buyer shall adjourn or postpone the Buyer Shareholder Meeting, if, as of the time for which such meeting is originally scheduled there are insufficient shares of Buyer Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated pursuant to Section 8.1 prior to the scheduled time of the Buyer Shareholder Meeting, the Buyer Shareholder Meeting shall be convened and this Agreement shall be submitted to the shareholders of Buyer at the Buyer Shareholder Meeting for the purpose of voting on the adoption of this Agreement and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve Buyer of such obligation.

(c)Unless and until this Agreement is terminated, Buyer and Seller will use their respective commercially reasonable best efforts to hold the Seller Shareholder Meeting and the Buyer Shareholder Meeting on the same date and at approximately the same time.

(b)To the extent required, Buyer shall file with Nasdaq a notification form for the listing of all shares of Buyer Common Stock included in the Merger Consideration, and shall use its commercially reasonable best efforts to cause such shares of Buyer Common Stock to be authorized for listing on the Nasdaq, subject to official notice of issuance, prior to the Effective Time.

(c)Before the Effective Time, Buyer shall cause any acquisitions of Buyer Common Stock resulting from the transactions contemplated by this Agreement by each individual who will become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Buyer to be exempt under Rule 16b-3 promulgated under the Exchange Act.

6.5 Employee Matters.

(a)Following the Effective Time, Buyer shall maintain or cause to be maintained employee benefit plans for the benefit of employees of Seller and CB who continue their employment after the Effective Time (“Covered Employees”) that provide employee benefits which are substantially comparable with respect to all material features to the employee benefits that are made available to similarly situated employees of Buyer or its Subsidiaries (other than Seller and CB), as applicable; provided that (i) in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of Buyer or its Subsidiaries; and (ii) until such time as Buyer shall cause Covered Employees to participate in the benefit plans that are made available to similarly situated employees of Buyer or its Subsidiaries (other than Seller and CB), a Covered Employee’s continued participation in employee benefit plans of Seller and CB shall

be deemed to satisfy the foregoing provisions of this sentence (it being understood that participation in the Buyer Benefit Plans may commence at different times with respect to each Buyer Benefit Plan).

(b)To the extent that a Covered Employee becomes eligible to participate in a Buyer Benefit Plan, Buyer shall cause such Buyer Benefit Plan to (i) recognize full-time years of prior service from the most recent hire of such Covered Employee with Seller or CB for purposes of eligibility, participation, and vesting but not for the purposes of benefit accruals, but only to the extent that such service was recognized immediately prior to the Effective Time under a comparable Seller Benefit Plan in which such Covered Employee was eligible to participate immediately prior to the Effective Time; provided that such recognition of service shall not operate to duplicate any benefits of a Covered Employee with respect to the same period of service; (ii) with respect to any Buyer Benefit Plan that is a health, dental, vision plan or other similar plan in which any Covered Employee is eligible to participate for the plan year in which such Covered Employee is first eligible to participate, Buyer or its applicable Subsidiary shall use its commercially reasonable best efforts to (A) cause any pre-existing condition limitations or eligibility waiting periods under such Buyer or Subsidiary plan to be waived with respect to such Covered Employee to the extent such condition was or would have been covered under the Seller Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time, or to the extent the Covered Employee has or had satisfied the applicable eligibility waiting period under the Seller Benefit Plan, and (B) recognize any health, dental, vision or other similar expenses incurred by such Covered Employee in the year that includes the Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate) for purposes of any applicable deductible and annual out-of-pocket expense requirements under any such health, dental, vision or other welfare plan; and (iii) for purposes of vacation or paid time off (“PTO”) benefits, Buyer will treat service of a Covered Employee at Seller or CB as equivalent to service at Buyer for determining such Covered Employee’s eligibility and participation under the Buyer vacation or PTO plan, and any vacation or PTO taken prior to the Closing Date (or such later date when PTO plans or programs are integrated) shall be subtracted under the Buyer plan from the Covered Employee’s maximum vacation or PTO entitlement for the calendar year in which the Closing Date occurs and any vacation or PTO carried over from a prior calendar year pursuant to Seller’s plan or program shall be added under the Buyer’s plan to the extent accrued on the books of Seller, or reflected in the Seller Financial Statements, prior to Closing.

(c)Prior to the Effective Time, Seller shall take, and shall cause CB to take, all actions reasonably requested by Buyer that may be necessary or appropriate to (i) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any Seller Benefit Plan for such period as may be requested by Buyer, (ii) facilitate the merger of any Seller Benefit Plan into any employee benefit plan maintained by Buyer or a Buyer Subsidiary, (iii) amend or terminate the Seller Benefit Plans (to the extent permitted by the terms thereof and Section 409A of the Code) immediately prior to the Effective Time, other than as provided in other subsections of this Section 6.5 and/or (iv) assign to Buyer and Southern Bank each of the Employee Confidentiality and Non-Solicitation Agreements set forth in Section 6.5(c) of the Seller Disclosure Schedule. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section 6.5(c) shall be subject to Buyer’s prior review and approval, which shall not be unreasonably withheld.

(d)All employment, change in control and severance agreements listed in Section 6.5(d) of the Seller Disclosure Schedule and the benefits vested under the other Seller Benefit Plans, in each case with respect to employees, officers, directors and consultants of Seller or CB or affiliates who are not retained immediately following the Effective Time, or who do not enter into new employment, change in control or severance agreements with Buyer prior to the Effective Time, shall be honored by the Surviving Company or a Buyer Subsidiary. Buyer shall pay all change in control payments in accordance with the employment and change in control agreements listed in Section 6.5(d) of the Seller Disclosure Schedule or, to the extent permissible under the terms of such agreements, in accordance with termination or waiver

arrangements with respect to such agreements that, in form and substance, are reasonably acceptable to Buyer. Buyer shall cause Southern Bank to provide to any employee who is not otherwise entitled to contractual or other severance or change in control benefits, a severance benefit in the amount of one (1) week base pay for each full year of full time employment with Seller or CB from his or her most recent hire date with a minimum severance benefit of two (2) weeks and a maximum severance benefit of twenty-six (26) weeks’ base pay, if and only if (i) such employee’s employment is involuntarily terminated by Southern Bank without cause at the Effective Time or within one (1) year following the Effective Time and (ii) such employee executes a release of all employment claims, which release shall be in a form that complies with Section 409A of the Code and is reasonably acceptable to Southern Bank. Buyer has provided to Seller a copy of its form of release. For purposes of this Section 6.5(d), “cause” shall mean (A) a material act of personal dishonesty in performing employee’s duties, (B) willful misconduct, (C) a breach of fiduciary duty or duty of loyalty involving personal profit, (D) the intentional failure to perform duties of such employee’s position, and (E) a willful violation of any law, rule or regulation (other than minor or routine traffic violations or similar offenses) that reflects adversely on the reputation of Seller, CB, or their successors, any felony conviction, any violation of law involving moral turpitude, or any violation of a final cease-and-desist order.

(e)Nothing in this Agreement shall confer upon any employee, officer, director or consultant of Buyer or Seller or any of their Subsidiaries or affiliates any right to continue in the employ or service of the Surviving Company, Seller, Buyer or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Company, Seller, Buyer or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of Buyer or Seller or any of their Subsidiaries or affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to alter or limit the ability of the Surviving Company or any of its Subsidiaries or affiliates to amend, modify or terminate any particular Seller Benefit Plan, Buyer Benefit Plan, or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of the final sentence of Section 9.9, nothing in this Section 6.5, express or implied, is intended to or shall confer upon any third party, including without limitation any current or former employee, officer, director or consultant of Buyer or Seller or any of their Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Section 6.5.

(f)In the event that any disqualified individual of Seller or CB receives any payments, benefits or acceleration of vesting (the “Total Payments”) in connection with the Merger that would constitute an “excess parachute payment” within the meaning of Section 280G of the Code that is subject to the Tax imposed by Section 4999 of the Code, then Seller will take all steps necessary to ensure that the Total Payments will be reduced such that the value of the Total Payments that each counterparty is entitled to receive shall be $1.00 less than the maximum amount which the counterparty may receive without becoming subject to the excise tax or resulting in a disallowance of a deduction of the payment of such amount under Section 280G of the Code.

6.6 Officers’ and Directors’ Insurance; Indemnification.

(a)Buyer agrees to provide each of the directors, officers, members or trustees of Seller or the Seller’s Subsidiaries who continue to hold such positions after the Effective Time substantially the same insurance coverage against personal liability for actions and omissions prior to the Effective Time, on terms no less favorable than that which is provided to current directors and officers of Buyer and Southern Bank. Without limiting the generality of the preceding sentence, on or prior to the Effective Time Buyer shall purchase, a prepaid “tail” or runoff policy reasonably acceptable to Buyer and Seller providing single limit equivalent coverage for the benefit of officers and directors of Seller or Seller’s Subsidiaries (but only in their capacity as such) immediately prior to Closing, covering actions, omissions, events, matters and circumstances occurring prior to the Effective Time for a period of up to six (6) years following

the Effective Time and providing coverages equivalent to the level and scope of directors’ and officers’ liability and other professional insurance coverages as set forth in Seller’s and Seller’s Subsidiaries’ current directors’ and officers’ liability and other professional insurance policies in effect as of the Closing. The premium cost for such policy or policies shall not be required to exceed 200% of the aggregate annual premium paid by Seller for the current insurance policy term(s) for such purpose. Buyer shall cause such policy to be maintained in full force and effect for its full term, and shall cause all obligations thereunder to be honored by Buyer and no other party shall have any further obligation to purchase or pay for insurance hereunder. The officers and directors of Seller may be required to make application and provide customary representations and warranties to Seller’s insurance carrier for the purpose of obtaining such insurance.

(b)For six (6) years from and after the Effective Time, Buyer shall indemnify and hold harmless each person who is now, or who has been at any time before the date of this Agreement, or who becomes before the Effective Time, a director or officer of Seller or CB (each, a “Seller Indemnified Party”) against all losses, claims, damages, costs, expenses (including reasonable attorneys’ fees), liabilities or judgments or amounts that are paid in settlement (which settlement shall require the prior written consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed) of or in connection with any claim, action, suit, proceeding, investigation or other legal proceeding, whether civil, criminal, administrative or investigative or investigation (each, a “Claim”), in which a Seller Indemnified Party is, or is threatened to be made, a party or witness or arising out of the fact that such person is or was a director or officer of Seller or CB if such Claim pertains to any matter of fact arising, existing or occurring at or before the Effective Time (including the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the fullest extent permitted under the organizational documents of Seller and CB as in effect at the Effective Time and to the fullest extent otherwise permitted by law.

(c)In connection with the indemnification provided pursuant to Section 6.6(b), Buyer and/or a Buyer Subsidiary (i) will advance expenses, promptly after statements therefor are received, to each Seller Indemnified Party to the fullest extent permitted by law and Governmental Entities (provided the individual to whom expenses are advanced provides an undertaking to repay such advance if it is ultimately determined that such individual is not entitled to indemnification), including the payment of the fees and expenses of one counsel with respect to a matter, and one local counsel in each applicable jurisdiction, if necessary or appropriate, selected by such Seller Indemnified Party or multiple Seller Indemnified Parties, it being understood that they collectively shall only be entitled to one counsel and one local counsel in each applicable jurisdiction where necessary or appropriate (unless a conflict shall exist between them in which case they may retain separate counsel), all such counsel shall be reasonably satisfactory to Buyer and (ii) will cooperate in the defense of any such matter.

(d)This Section 6.6 shall survive the Effective Time, is intended to benefit each Seller Indemnified Party (each of whom shall be entitled to enforce this Section against Buyer), shall be binding on all successors and assigns of Buyer and shall not be modified or terminated after the Effective Time in a manner so as to adversely affect any Seller Indemnified Party without the written consent of the affected Seller Indemnified Party.

(e)Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ or officers’ insurance claims under any policy that is or has been in existence with respect to Seller or CB for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 6.5 is not prior to or in substitution for any such claims under such policies.

(f)In the event Buyer or any of its successors or assigns (i) consolidates with or merges into any other person or entity and shall not be the continuing or surviving company or entity of

such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to one or more other persons or entities, then, and in each such case, proper provision shall be made so that the successors and assigns of Buyer assume the obligations set forth in this Section 6.6.

6.7 No Solicitation.

(a)Seller agrees that, except as expressly permitted by Section 6.7(b), from the date of this Agreement until the Effective Time or, if earlier, the termination of this Agreement in accordance with Section 8.1, it will not, and will cause its Subsidiaries and its Subsidiaries’ officers, directors, and employees (the “Seller Individuals”) not to, and will use its commercially reasonable best efforts to cause Seller and its Subsidiaries’ agents, advisors and controlled affiliates, accountants, legal counsel, and financial advisors (the “Seller Representatives”) not to, initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, or engage in any discussions or negotiations concerning, or provide any confidential or nonpublic information or data concerning its and/or its Subsidiaries business, properties or assets (“Seller Confidential Information”) to, or have any discussions with, any person or entity relating to, any Acquisition Proposal (as defined below). Seller will immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any persons or entities other than Buyer with respect to any Acquisition Proposal and will use its commercially reasonable best efforts, subject to applicable law, to enforce any confidentiality or similar agreement relating to such an Acquisition Proposal.

(b)Notwithstanding anything to the contrary in Section 6.7(a), at any time from the date of this Agreement and prior to obtaining the Seller Shareholder Approval, in the event Seller receives an unsolicited Acquisition Proposal and the board of directors of Seller determines in good faith that such Acquisition Proposal constitutes a Superior Proposal (as defined below) or is reasonably likely to result in a Superior Proposal, Seller may, and may permit its Subsidiaries and the Seller Individuals and the Seller Representatives to, (i) negotiate the terms of, and enter into, a confidentiality agreement with terms and conditions no less favorable to Seller than the Confidentiality Agreement (an “Acceptable Confidentiality Agreement”), (ii) furnish or cause to be furnished Seller Confidential Information to the person or entity making such Acquisition Proposal pursuant to an Acceptable Confidentiality Agreement, and (iii) negotiate and participate in such negotiations or discussions with the person or entity making such Acquisition Proposal concerning such Acquisition Proposal, if the board of directors of Seller determines in good faith (following consultation with counsel) that failure to take such actions would result in a violation of its fiduciary duties under applicable law.

(c)The board of directors of Seller shall not (nor shall any committee thereof) withdraw or modify, in a manner adverse to Buyer, the Seller Board Recommendation or make or cause to be made any third party or public communication proposing or announcing an intention to withdraw or modify in any manner adverse to Buyer the Seller Board Recommendation (any such action, a “Seller Change in Recommendation”) except as provided in this Section 6.7(c). The board of directors of Seller (including any committee thereof) may, at any time prior to obtaining the Seller Shareholder Approval, effect a Seller Change in Recommendation in response to a bona fide written unsolicited Acquisition Proposal made after the date of this Agreement that the board of directors of Seller determines in good faith (after consultation with Seller’s outside legal counsel) constitutes a Superior Proposal; provided, however, that the board of directors of Seller may not make a Seller Change in Recommendation, or terminate this Agreement pursuant to Section 8.1(f), with respect to an Acquisition Proposal until it has given Buyer at least four (4) business days, following Buyer’s initial receipt of written notice that the board of directors of Seller has determined that such Acquisition Proposal is a Superior Proposal and the reasons therefor, to respond to any such Acquisition Proposal and, taking into account any amendment or modification to this Agreement proposed by Buyer, the board of directors of Seller determines in good faith (after consultation with counsel) that such Acquisition Proposal continues to constitute a Superior Proposal. Notwithstanding

anything in this Agreement to the contrary, in circumstances not involving or relating to an Acquisition Proposal, at any time prior to the receipt of the Seller Shareholder Approval, the board of directors of Seller (including any committee thereof) may make a Seller Change in Recommendation if (i) the board of directors becomes aware of an Intervening Event, (ii) the board of directors of Seller has concluded in its reasonable judgment (after consultation with its outside legal counsel and financial advisors) that failure to take such action would be reasonably expected to be inconsistent with the directors’ fiduciary duties under applicable law, (iii) four (4) business days (the “Intervening Event Notice Period” ) shall have elapsed since the Seller has given written notice (which written notice shall not, in and of itself, be deemed a Seller Change in Recommendation for any purpose of this Agreement) to Buyer advising that the Seller intends to take such action and specifying in reasonable detail the reasons therefor, (iv) during such Intervening Event Notice Period, the Seller has considered and, if requested by Buyer, engaged and caused its representatives to engage in good faith discussions with Buyer regarding any adjustment or modification of the terms of this Agreement proposed by Buyer, and (E) the board of directors of Seller, following such Intervening Event Notice Period, again determines in its reasonable judgment (after consultation with its outside legal counsel and its financial advisors, and taking into account any adjustment or modification of the terms of this Agreement proposed by Buyer) that failure to do so would be reasonably expected to be inconsistent with the directors’ fiduciary duties under applicable law. “Intervening Event” means a material fact or any change, development, event, effect or occurrence that (i) was not known or could not have been reasonably known by the board of directors of Seller as of the date of this Agreement (or if known, the consequences of which were not known or reasonably foreseeable), (ii) becomes known to the board of directors of Seller prior to Seller Shareholder Approval and (iii) does not relate to or constitute an Acquisition Proposal or any inquiry, proposal or offer relating to or that would reasonably be expected to lead to an Acquisition Proposal and (iv) would be reasonably expected to result in a Material Adverse Effect.

(d)Seller will promptly (and in any event within two (2) business days) advise Buyer in writing following receipt of any Acquisition Proposal and the substance thereof (including the identity of the person or entity making such Acquisition Proposal), and will keep Buyer apprised of any related developments, discussions and negotiations (including the terms and conditions, whether written or oral, of the Acquisition Proposal) on a current basis.

As used in this Agreement, the following terms have the meanings set forth below:

“Acquisition Proposal ” means a tender or exchange offer, proposal for a merger, consolidation or other business combination involving Seller or CB or any proposal or offer to acquire in any manner more than 24.99% of the voting power in, or more than 24.99% of the fair market value of the business, assets or deposits of, Seller or CB, other than the transactions contemplated by this Agreement.

“Superior Proposal ” means a written Acquisition Proposal that the board of directors of Seller concludes in good faith to be more favorable from a financial point of view to its shareholders than the Merger, (i) after receiving the advice of its financial advisors (ii) after taking into account the likelihood of consummation of such transaction on the terms set forth therein and (iii) after taking into account all legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal and any other relevant factors permitted under applicable law; provided, however, that for purposes of the definition of “Superior Proposal,” the references to “more than 24.99%” in the definition of Acquisition Proposal shall be deemed to be references to “a majority”.

6.8Notification of Certain Matters. Each of the Parties shall give prompt written notice to the other of any fact, event or circumstance known to it that (a) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (b) would cause or constitute a breach of any of its representations, warranties,

covenants or agreements contained herein. Each of Seller and Buyer shall promptly inform the other in writing upon receiving notice of any claim, demand, cause of action or investigation by any Governmental Entity or third party against, or threatened against, it or any of its Subsidiaries or any of their respective assets, properties, or any of their respective directors, officers or employees in their individual capacities as such.

6.9Correction of Information. Each of Seller and Buyer shall promptly correct and supplement in writing any information furnished under this Agreement so that such information shall be correct and complete in all material respects at all times, without taking into account any Material Adverse Effect qualification, and shall include all facts necessary to make such information correct and complete in all material respects at all times; provided, however, that in each case, such disclosure shall not be deemed to cure any breach of a representation, warranty, covenant or agreement or any failure of a condition under Article VII, or to otherwise limit or affect in any way the remedies available hereunder to any party.

6.10 Integration. From and after the date hereof, Seller shall, and shall cause CB and its and CB’s directors, officers and employees to, make all commercially reasonable efforts (without undue disruption to either business) to (i) cooperate in order to permit Southern Bank to train CB employees who are expected to continue employment with Southern Bank, including excusing such employees from their duties for the purpose of training and orientation by Southern Bank following reasonable advance notice and (ii) cause CB’s data processing consultants and software providers to, cooperate and assist CB and Southern Bank in connection with reasonable requests as to scope, timing and content related to the planned electronic and systematic conversion of all applicable data of CB to the Southern Bank system to occur after the Effective Time, in each case without undue disruption to CB’s business, during normal business hours and at the expense of Buyer or Southern Bank (not to include CB’s regular employee payroll); provided, that (1) Seller shall not be required to take any action under this Section 6.10 that, after providing Buyer with notice of Seller’s concerns in the matter, would prejudice or adversely affect in any material respect its rights under any such contracts in the event the Closing does not occur, and (2) Seller shall not be required to provide access to or disclose information (i) which would violate or prejudice the rights of Seller’s customers, jeopardize attorney-client privilege of Seller or contravene any binding agreement entered into prior to the date of this Agreement or any law, rule regulation, order, judgment, decree or fiduciary duty; (ii) except as otherwise provided in this Agreement, related to the Seller’s directors’, officers’, employees’, accountants’, counsels’, advisors’, (including investment bankers’) agents’ or other representatives’ consideration of, or deliberations regarding, the transactions contemplated by this Agreement or with respect to any Acquisition Proposal (except as set forth in Section 6.7 of this Agreement); or (iii) the disclosure of which would violate applicable law, rule regulation, order, judgment, decree or (iv) otherwise reasonably deemed by the Buyer or Seller board of directors to be confidential.

6.11Coordination; Integration. Subject to applicable law and regulation, during the period from the date hereof until the Effective Time, Seller shall cause the Chief Executive Officer, Chief Financial Officer, and President of CB to assist and confer with the officers of Southern Bank, on a periodic basis, relating to the development, coordination and implementation of the post-Merger operating and integration plans of Southern Bank, as the Surviving Bank in the Bank Merger.

6.12Delivery of Agreements. Seller shall cause the Voting Agreements and the Non-Compete Agreements to be executed by all directors and executive officers and delivered to Buyer prior to or simultaneously with the execution of this Agreement.

6.13Directors. Buyer agrees to take all necessary corporate action to cause one member of Seller’s current board of directors to be appointed as a director of Buyer, for a term expiring at the 2025 annual meeting of the shareholders of Buyer, and a director of Southern Bank at the Effective Time.

6.14Press Releases. Each of Seller and Buyer agrees that it will not, without the prior approval of the other party, file any material pursuant to SEC Rules 165 or 425, or issue any press release or written statement for general circulation relating to the transactions contemplated hereby, except as otherwise required by applicable law or regulation or Nasdaq rules.

Article VIII

TERMINATION AND AMENDMENT

8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after the Seller Shareholder Approval, by action of the board of directors of a party, as follows:

(a)by the written mutual consent of Seller and Buyer (acting on behalf of itself and Merger Sub);

(b)by either Seller or Buyer, if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Mergers or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction or decree permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform any covenant or agreement in this Agreement required to be performed prior to the Effective Time;

(c)by either Seller or Buyer, if the Merger shall not have been consummated on or before June 30, 2023 (the “Termination Date” ), with an understanding that all parties will make every commercially reasonable best effort to hold the Closing within thirty (30) days following the receipt of the later of regulatory approval or both shareholder approvals, but in no event prior to January 1, 2023, unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth in this Agreement; and provided, further, that if additional time is necessary in order to obtain any Requisite Regulatory Approvals, the Termination Date shall be automatically extended for one additional two-month period.

(d)by either Seller or Buyer (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties set forth in this Agreement on the part of Seller, in the case of a termination by Buyer, or Buyer, in the case of a termination by Seller, which breach, either individually or in the aggregate, would result in, if occurring or continuing on the Closing Date, the failure of any of the conditions set forth in Section 7.2 or 7.3, as the case may be, and which is not cured within twenty (20) days following written notice to the party committing such breach or by its nature or timing cannot be cured within such time period (or such fewer days as remain prior to the Termination Date);

(e)(i) by Buyer prior to the Seller Shareholder Approval being obtained if (A) the board of directors of Seller shall have failed to make the Seller Board Recommendation or the board of directors of Seller or any committee thereof shall have made a Seller Change in Recommendation or (B) Seller shall have materially breached any of the provisions set forth in Section 6.7 or (C) Seller shall have refused to call or hold the Seller Shareholder Meeting (unless this Agreement is terminated prior to the Seller Shareholder Meeting pursuant to Section 8.1(f)) or (ii) by Seller prior to the Buyer Shareholder Approval being obtained if (A) the board of directors of Buyer shall have failed to make the Buyer Board Recommendation or the board of directors of Buyer or any committee thereof shall have made a Buyer Change in Recommendation or (B) Buyer shall have refused to call or hold the Buyer Shareholder Meeting;

(f)by Seller prior to obtaining the Seller Shareholder Approval in order to enter into an agreement relating to a Superior Proposal in accordance with Section 6.7; provided, however, that Seller

has (i) not materially breached the provisions of Section 6.7, and (ii) complied with its payment obligation under Section 8.4(a);

(g)by either Seller or Buyer, (i) if the provisions of Section 8.1(e)(i) are not applicable and the shareholders of Seller fail to provide the Seller Shareholder Approval at a duly held meeting of shareholders or at an adjournment or postponement thereof or (ii) if the provisions of Section 8.1(e)(ii) are not applicable and the shareholders of Buyer fail to provide the Buyer Shareholder Approval at a duly held meeting of shareholders or at an adjournment or postponement thereof; or

(h)By Seller if, at any time during the five business day period commencing on the Determination Date, each of the following conditions is satisfied: (A) the Buyer Market Value on the Determination Date is less than $42.02 and (B) (I) the number obtained by dividing (x) the Buyer Market Value on the Determination Date, by (y) the Initial Buyer Market Value, is less than (II) the number obtained by subtracting 0.20 from the Index Ratio; subject to the following four sentences. Any such termination shall be effective on the fifteenth business day following the Determination Date; subject to the following three sentences. If Seller elects to exercise its termination right pursuant to this Section 8.1(h), it shall give prompt written notice thereof to Buyer. During the five business day period commencing with its receipt of such notice, Buyer shall have the option to increase the Per Share Stock Consideration to equal the lesser of (x) a quotient, the numerator of which is equal to the product of Initial Buyer Market Value, the Per Share Stock Consideration, and the Index Ratio minus 0.20, and the denominator of which is equal to the Buyer Market Value on the Determination Date; or (y) the quotient determined by dividing the Initial Buyer Market Value by the Buyer Market Value on the Determination Date, and multiplying the quotient by the product of the Per Share Stock Consideration and 0.80. If within such five business day period, Buyer delivers written notice to the Seller that it intends to proceed with the Merger by paying such additional consideration as contemplated by the preceding sentence, and notifies the Seller of the revised Per Share Stock Consideration, then no termination shall have occurred pursuant to this Section 8.1(h), and this Agreement shall remain in full force and effect in accordance with its terms (except that the Per Share Stock Consideration shall have been so modified). For purposes of clarification, the adjustments to the Merger Consideration contemplated by Section 1.4(c)(ii) of this Agreement shall be calculated and applied subsequent to any adjustment to the Per Share Stock Consideration pursuant to this Section 8.1(h). If Buyer or any company belonging to the Index declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction between the date of this Agreement and the Determination Date, the prices for the common stock of such company shall be appropriately adjusted for the purposes of applying this Section 8.1(h).

For purposes of this Section 8.1(h), the following terms shall have the following definitions:

“Buyer Market Value” means, as of any specified date, the average of the daily closing sales prices of a share of Buyer Common Stock as reported on the Nasdaq Global Market for the twenty (20) consecutive trading days immediately preceding such specified date.

“Determination Date” means the fifteenth business day preceding the Closing Date.

“Final Index Price” means the average of the daily closing value of the Index for the twenty (20) consecutive trading days immediately preceding the Determination Date, subject to adjustment pursuant to the last sentence of Section 8.1(h).

“Index” means the Nasdaq Bank Index or, if such index is not available, such substitute or similar index as substantially replicates the Nasdaq Bank Index.

“Index Ratio” means the Final Index Price divided by the Initial Index Price.

“Initial Index Price” means the average of the daily closing value of the Index for the 20 consecutive trading days immediately preceding the execution of this Agreement.

“Initial Buyer Market Value” means the Buyer Market Value as of the date of this Agreement.

The party desiring to terminate this Agreement pursuant to clause (b), (c), (d), (e), (f), (g), or (h) of this Section 8.1 shall give written notice of such termination to the other party in accordance with Section 9.3, specifying the provision or provisions hereof pursuant to which such termination is effected.

8.2 Effect of Termination. In the event of termination of this Agreement by either Seller or Buyer as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, and none of Seller, Buyer, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever under this Agreement, or in connection with the transactions contemplated by this Agreement, except that (i) Sections 8.2, 8.3, 8.4, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, 9.10 and 9.11 shall survive any termination of this Agreement, and (ii) if this Agreement is terminated under Section 8.1(d), the non-terminating party shall not, except as provided in Section 8.4(c), be relieved or released from any liabilities or damages arising out of its willful and material breach of any provision of this Agreement.

8.3 Fees and Expenses. Except with respect to costs and expenses of printing and mailing the Proxy Statement, which shall be borne by Buyer, and all filing and other fees in connection with any filing with the SEC, which shall be borne by Buyer, and all transfer, documentary, sales, use, stamp, registration and other similar Taxes, and all conveyance fees, recording charges and other similar fees and charges incurred in connection with the consummation of the transactions contemplated hereby, which shall be borne by Buyer except as provided in Section 2.3(d), all fees and expenses (including the Termination Fee in Section 8.4) incurred in connection with the Merger, the Bank Merger, this Agreement, and the other transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated.

8.4 Termination Fee.

(a)If this Agreement is terminated pursuant to Section 8.1(e)(i) or (f), then (i) in the case of termination under Section 8.1(e)(i), so long as Buyer has made and maintains its Buyer Board Recommendation up until such termination without any Buyer Change in Recommendation then Seller shall immediately following such termination pay Buyer an amount equal to five million five hundred thousand dollars ($5,500,000) (the “Termination Fee”), and (ii) in the case of termination under Section 8.1(f), Seller shall, simultaneously with such termination and as a condition thereof, pay Buyer the Termination Fee, in each case in same-day funds.

(b)If this Agreement is terminated by either party under Section 8.1(g)(i), and prior thereto there has been publicly announced a bona fide Acquisition Proposal which has not been publicly withdrawn at least three business days prior to the Seller Shareholder Meeting, then if within one year of such termination Seller or CB either (A) enters into a definitive agreement with respect to an Acquisition Proposal or (B) consummates an Acquisition Proposal, Seller shall within five business days thereafter pay Buyer the Termination Fee set forth in Section 8.4(a) in same-day funds. For purposes of clauses (A) and (B) above, the reference to 24.99% in the definition of Acquisition Proposal shall be 50.0%.

(c)The payment of the Termination Fee shall fully discharge Seller from any and all liability under this Agreement and related to the transactions contemplated herein, and Buyer shall not be entitled to any other relief or remedy against Seller. If the Termination Fee is not payable, Buyer may pursue any and all remedies available to it against Seller on account of a willful and material breach by Seller of

any of the provisions of this Agreement. Moreover, if the Termination Fee is payable pursuant to Section 8.1(e)(i)(B), Buyer shall have the right to pursue any and all remedies available to it against Seller on account of the willful and material breach by Seller of Section 6.7 in lieu of accepting the Termination Fee under Section 8.4(a). Seller may pursue any and all remedies available to it against Buyer on account of a willful and material breach by Buyer of any of the provisions of this Agreement.

8.5Amendment. This Agreement may be amended by the Parties, by action taken or authorized by their respective boards of directors, at any time before or after approval of the matters presented in connection with the Merger by the shareholders of Seller or Buyer; provided, however, that after any approval of the transactions contemplated by this Agreement by the shareholders of Seller, there may not be, without further approval of such shareholders, any amendment of this Agreement that requires further approval under applicable law. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

8.6Extension; Waiver. At any time prior to the Effective Time, the Parties, by action taken or authorized by their respective board of directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other party, (b) waive any inaccuracies in the representations and warranties contained in this Agreement or (c) waive compliance with any of the agreements or conditions contained in this Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

9.2Nonsurvival of Representations, Warranties and Agreements.

9.4 Interpretation. This Agreement has been negotiated and prepared by the Parties and their respective counsel. This Agreement shall be fairly interpreted in accordance with its terms and without any strict construction in favor or against either party. When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” Whenever reference is made to the “knowledge” of Seller, it shall mean to the actual knowledge of Roger Arwood, Bill Young, Jon Appleby, Bill Dippel, Jim Conley, Mark Eagleton, and Rick Viar. Whenever reference is made to the “knowledge” of Buyer or Merger Sub, it shall mean to the actual knowledge of any executive officer or director of such party. All schedules and exhibits hereto shall be deemed part of this Agreement and included in any reference to this Agreement. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal or state regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to give effect to the original intent of the Parties as closely as possible in a reasonably acceptable manner in order that the transactions contemplated hereby may be consummated as originally contemplated to the fullest extent possible. If for any reason such court or regulatory agency determines that any provision, covenant or restriction is invalid, void or unenforceable, it is the express intention of the Parties that such provision,

covenant or restriction be enforced to the maximum extent permitted. No matter or item disclosed in the Buyer Disclosure Schedule or Seller Disclosure Schedule admitting or indicating a possible breach or violation of any contract, statute, law, regulation, ordinance, rule, judgment, order or decree shall be construed as an admission or indication that an actual breach or violation exists, has actually occurred or will occur. The Parties do not assume any responsibility to any Person that is not a Party to this Agreement for the accuracy of any information set forth in the Buyer Disclosure Schedule or Seller Disclosure Schedule. Subject to applicable law, the information in the Buyer Disclosure Schedule or Seller Disclosure Schedule is disclosed in confidence for the purposes contemplated in this Agreement and is subject to the confidentiality provisions of any other agreements, including the Confidentiality Agreement, entered into by the Parties or their affiliates. Moreover, in disclosing the information in the Buyer Disclosure Schedule or Seller Disclosure Schedule, each disclosing Party expressly does not waive any attorney-client privilege associated with such information or any protection afforded by the work-product doctrine with respect to any of the matters disclosed or discussed therein.

9.5 Counterparts. This Agreement may be executed in two or more counterparts (including by facsimile or other electronic means), all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to the other party, it being understood that each party need not sign the same counterpart.

9.6 Entire Agreement. This Agreement (including the documents and the instruments referred to in this Agreement), together with the Confidentiality Agreement, constitutes the entire agreement and supersedes all prior written, and prior or contemporaneous oral, agreements and understandings, between the Parties with respect to the subject matter of this Agreement, other than the Confidentiality Agreement.

9.7 Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Missouri applicable to contracts made and performed entirely within such state, without regard to any applicable conflicts of law principles or any other principle that could require the application of the application of the law of any other jurisdiction. The Parties hereto agree that any suit, action or proceeding brought by either party to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal or state court located in the State of Missouri. Each of the Parties hereto submits to the jurisdiction of any such court in any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of, or in connection with, this Agreement or the transactions contemplated hereby and hereby irrevocably waives the benefit of jurisdiction derived from present or future domicile or otherwise in such action or proceeding. Each party hereto irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. This Agreement has been negotiated and prepared by the Parties and their respective counsel. This Agreement shall be fairly interpreted in accordance with its terms and without any strict construction in favor or against either party.

9.8 Publicity. Neither Seller nor Buyer shall, and neither Seller nor Buyer shall permit any of its Subsidiaries to, issue or cause the publication of any press release or other public announcement with respect to, or otherwise make any public statement concerning, the transactions contemplated by this Agreement without the prior consent (which shall not be unreasonably withheld or delayed) of Buyer, in the case of a proposed announcement or statement by Seller, or Seller, in the case of a proposed announcement or statement by Buyer; provided, however, that either party may, without the prior consent of the other party (but after prior consultation with the other party to the extent practicable under the circumstances) issue or cause the publication of any press release or other public announcement to the extent required by law or by the rules and regulations of the Nasdaq.

9.9 Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned by either of the Parties (whether by operation of law or otherwise) without the prior written consent of the other party (which shall not be unreasonably withheld or delayed). Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by each of the Parties and their respective successors and permitted assigns. Except for Section 1.4, which is intended to confer upon Holders rights to the Merger Consideration upon Closing as set forth therein, and Section 6.6, which is intended to benefit each indemnified person referenced therein, or as otherwise specifically provided herein, this Agreement (including the documents and instruments referred to in this Agreement) is not intended to and does not confer upon any person other than the Parties hereto any rights or remedies under this Agreement.

9.10 Specific Performance; Time of the Essence. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or are otherwise breached or threatened to be breached. It is accordingly agreed that the Parties and the third party beneficiaries of this Agreement shall be entitled to equitable relief, without proof of actual damages, including an injunction or specific performance to prevent breaches of this Agreement or to enforce specifically the terms hereof, without the necessity of demonstrating irreparable harm or posting of any bond or security, in addition to any other remedies to which they are entitled at law or equity. The only objection that a Party may raise in response to any action for equitable relief is that such Party contests the existence of a breach or threatened breach of this Agreement. The Parties agree that seeking remedies pursuant to this Section 9.10 will not in any respect constitute a waiver by any Party or any third party beneficiary of its respective right to seek any other form of relief that may be available to it in accordance with this Agreement or to exercise any right it has to terminate this Agreement, and that no Party or third party beneficiary is required to seek the remedies under this Section 9.10 prior to seeking any such other form of relief or exercising any such right it has to terminate this Agreement. Notwithstanding the foregoing, for the avoidance of doubt, following Closing, the Parties waive any right to rescind this Agreement or any of the transactions contemplated hereby. Time is of the essence for performance of the agreements, covenants and obligations of the Parties herein.

9.11 Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT: (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

Buyer, Merger Sub and Seller have caused this Agreement to be executed by their respective officers thereunto duly authorized as of the date first above written.

SOUTHERN MISSOURI BANCORP AND CITIZENS BANCSHARES CO. ANNOUNCE AGREEMENT TO MERGE

Poplar Bluff, Missouri - Southern Missouri Bancorp, Inc. (NASDAQ: SMBC, "Southern Missouri"), the parent corporation of Southern Bank, and Citizens Bancshares Co. ("Citizens"), the parent company of Citizens Bank and Trust Company, today announced the signing of a definitive merger agreement whereby Southern Missouri will acquire Citizens in a stock and cash transaction.

Citizens operates 14 banking centers throughout greater Kansas City, St. Joseph and Northwest Missouri. At June 30, 2022, Citizens’ consolidated assets were $1.0 billion, including net loans of $465 million, while deposits totaled $879 million.

Southern Missouri reported total assets at June 30, 2022, of $3.2 billion, including net loans of $2.7 billion, and total deposits of $2.8 billion. On a pro forma basis, following the acquisition, the combined company's total assets will approximate $4.5 billion, with net loans of $3.3 billion, and total deposits of $3.8 billion. The combined company will operate 65 locations in Missouri, Arkansas, and Illinois.

Greg Steffens, Chairman and Chief Executive Officer of Southern Missouri, commented, “Southern Missouri Bancorp is very pleased to announce this partnership with Citizens. Citizens’ franchise covers excellent communities, including the Kansas City metropolitan area. They have developed a strong deposit base and have a long history of serving their customers, which will be a great addition to our continued growth. Additionally, a presence in Kansas City helps transform Southern Missouri into a more significant statewide player in Missouri as we continue to build long-term shareholder value.”

“This merger provides an opportunity for Citizens to join forces with a growing organization, while remaining committed to community banking,” said Roger Arwood, President and Chief Executive Officer of Citizens. “We look forward to the opportunities and benefits this combination will bring to our customers and communities, in terms of a larger legal lending limit and broader branch coverage across Missouri.”

Matt Funke, President and Chief Administrative Officer for Southern Missouri, added, “In addition to the long-term strategic importance of access to these new markets, Citizens provides us with immediate benefits from their excellent deposit base, and a concentration of the asset side of their balance sheet in short-duration instruments. Their deposit base will help us to manage our cost of funds, and the structure of their assets will help us manage our interest rate risk in this environment of rapidly changing interest rates.”

Under the terms of the merger agreement, unanimously approved by the boards of both entities, Citizens’ shareholders will have the right to elect either a fixed exchange ratio of 1.1448 shares of Southern Missouri common stock or a cash payment of $53.50 for each Citizens’ share, subject to adjustment based on Citizens’ capital and the total outstanding shares of Citizens at closing. Based on Southern Missouri's average closing stock price of $52.53 over the 20-day trading period ended September 19, 2022, the aggregate transaction value is approximately $140 million.

The deal value equates to 150% of Citizens’ tangible capital at June 30, 2022, represents a 5.9% premium to core deposits, and is a multiple of 7.1 times Citizens’ projected forward earnings including fully phased-in cost savings, which are estimated at 35%. Excluding certain one-time merger charges, including Southern Missouri's additional provision for credit losses as required under ASU 2016-13 ("CECL''), the transaction is anticipated to be accretive to earnings per share by approximately 5% in our fiscal year ended June 30, 2023, and by 17% in our fiscal year ended June 30, 2024. Tangible book value per common share is expected to be diluted by approximately 8% at closing, with a projected earnback period of less than 2.75 years, based on the crossover method.

Southern Missouri and Citizens anticipate completion of the transaction early in the first calendar quarter of 2023, subject to satisfaction of customary closing conditions, including regulatory and shareholder approvals for both parties.

Piper Sandler & Co. acted as financial advisor and Silver, Freedman, Taff & Tiernan LLP served as legal advisor to Southern Missouri. D.A. Davidson & Co. acted as financial advisor and Stinson LLP served as legal advisor to Citizens.
