All of the shares offered by this prospectus are being sold by the Selling Stockholder. It is anticipated that the Selling Stockholder will sell the shares from time to time in one or more transactions, in negotiated transactions or otherwise, at prevailing market prices or at prices otherwise negotiated. The Selling Stockholder may offer and sell these securities to or through one or more underwriters, dealers or agents, or directly to purchasers, on a continuous or delayed basis. We do not know when or in what amounts the Selling Stockholder may offer the shares for sale. The Selling Stockholder might not sell all of the shares offered by this prospectus.

These securities are not bank deposits and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency, nor are they obligations of, or guaranteed by, a bank.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The information presented herein and in other documents filed with or furnished to the SEC, in press releases or other public stockholder communications, or in oral statements made with the approval of an authorized executive officer contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “project,” “forecast,” “goal,” “target,” “would” and “outlook,” or the negative variations of those words or other comparable words of a future or forward-looking nature. These forward-looking statements are not historical facts and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements described under the heading “Risk Factors” in our most recent Annual Report on Form 10-K.

There are or will be important factors that could cause our actual results to differ materially from those indicated in these forward-looking statements, including, but not limited to, the following:

• external economic and/or market factors, such as changes in monetary and fiscal policies and laws, including the interest rate policies of the Board of Governors of the Federal Reserve System, or the Federal Reserve, inflation or deflation, changes in the demand for loans, and fluctuations in consumer spending, borrowing and savings habits which may have an adverse impact on our financial condition;

• losses resulting from a decline in the credit quality of the assets that we hold;

• the occurrence of various events that negatively impact the real estate market, since a significant portion of our loan portfolio is secured by real estate;

• inaccuracies or changes in the appraised value of real estate securing the loans we originate that could lead to losses if the real estate collateral is later foreclosed upon and sold at a price lower than the appraised value;

• the loss of our largest loan and depositor relationships;

• limitations on our ability to lend and to mitigate the risks associated with our lending activities as a result of our size and capital position;

• differences in our realized losses as compared to historical loss experience adjusted for quantitative and qualitative factors reflected in our calculation of the allowance for credit losses;

• inadequacies in our allowance for credit losses which could require us to take a charge to earnings and thereby adversely affect our financial condition;

• interest rate fluctuations which could have an adverse effect on our profitability;

• an economic downturn, especially one affecting our core market areas;

• the effects of a pandemic or other widespread public health emergencies;

• the costs of integrating the businesses we acquire, which may be greater than expected;

• the departure of key members of our management personnel or our inability to hire qualified management personnel;

4

• challenges arising from unsuccessful attempts to expand into new geographic markets, products, or services;

• a lack of liquidity resulting from decreased loan repayment rates, lower deposit balances, or other factors;

• inaccuracies in our assumptions about future events which could result in material differences between our financial projections and actual financial performance;

• an inability to keep pace with the rate of technological advances due to a lack of resources to invest in new technologies;

• disruptions, security breaches, or other adverse events, failures or interruptions in, or attacks on, our information technology systems;

• unauthorized access to nonpublic personal information of our customers, which could expose us to litigation or reputational harm;

• disruptions, security breaches, or other adverse events affecting the third-party vendors who perform several of our critical processing functions;

• required implementation of new accounting standards that significantly change our existing recognition practices;

• additional regulatory requirements and restrictions on our business, which could impose additional costs on us;

• an increase in FDIC deposit insurance assessments, which could adversely affect our earnings;

• increased capital requirements imposed by banking regulators, which may require us to raise capital at a time when capital is not available on favorable terms or at all;

• restraints on the ability of Equity Bank to pay dividends to us, which could limit our liquidity;

• a failure in the internal controls we have implemented to address the risks inherent to the banking industry;

• continued or increasing competition from other financial institutions, credit unions, and non-bank financial services companies, many of which are subject to different regulations than we are;

• costs arising from the environmental risks associated with making loans secured by real estate;

• the occurrence of adverse weather or man-made events, which could negatively affect our core markets or disrupt our operations;

• the effects of new federal tax laws or tariffs, or changes to existing federal tax laws or tariffs;

• the obligations associated with being a public company;

• effect of pending and future litigation, including the results of the overdraft fee litigation against the Company that is described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024; and

• other factors that are discussed under “Risk Factors” beginning on page 9 of this prospectus.

The foregoing factors should not be construed as exhaustive and should be read in conjunction with other cautionary statements that are included in this prospectus. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date when it is made and we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new

5

information, future developments or otherwise. New risks and uncertainties arise from time to time and it is not possible for us to predict those events or how they may affect us. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements, expressed or implied, included in this prospectus are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

DESCRIPTION OF CAPITAL STOCK

The following discussion summarizes some of the important rights of our stockholders. This discussion does not purport to be a complete description of these rights and may not contain all of the information regarding our capital stock that is important to you. These rights can be determined in full only by reference to federal and state banking laws and regulations, the Kansas General Corporation Code, applicable law and our Articles of Incorporation and Bylaws, copies of which are filed with the SEC as exhibits to the registration statement of which this prospectus is a part.

General

We are incorporated in the State of Kansas. The rights of our stockholders are generally governed by Kansas law, our Second Amended and Restated Articles of Incorporation (“Articles of Incorporation”) and our Amended and Restated Bylaws (“Bylaws”). The terms of our common stock are therefore subject to Kansas law and federal law governing bank holding companies.

The following description of our Class A Common Stock is a summary and is subject to, and is qualified in its entirety by reference to, the provisions of our Articles of Incorporation and our Bylaws. For more detailed information about the rights of our Class A Common Stock, you should refer to our Articles of Incorporation, Bylaws and the applicable provisions of Kansas law for additional information.

Authorized Capital Stock

We are authorized to issue (i) 50,000,000 shares of common stock, par value $0.01 per share, of which (a) 45,000,000 shares are designated as Class A Common Stock, and (b) 5,000,000 shares are designated as Class B Non-Voting common stock (“Class B Common Stock”), and (ii) 10,000,000 shares of preferred stock. All outstanding shares of our Class A Common Stock are fully paid and non-assessable.

Voting Rights

Each holder of our Class A Common Stock is entitled to one vote per share on all matters to be voted on by our stockholders. Our stockholders do not have cumulative voting rights with respect to the election of directors. If we issue preferred stock, holders of our preferred stock may also possess voting rights. Our Class B Common Stock has no voting rights.

Subject to the rights of the holders of any preferred stock then outstanding, removal of any of directors without cause requires the affirmative vote of the holders of record of outstanding shares representing at least 66 2/3% of the voting power of all the shares of our capital stock then entitled to vote generally in the election of directors, voting together as a single class.

Our Articles of Incorporation provide that our board of directors is authorized to make, amend, alter or repeal our Bylaws, subject to the power of the stockholders, as described below, to make, amend, alter or repeal our Bylaws. Notwithstanding the foregoing, the affirmative vote of at least 66 2/3% of the voting power of all the shares of our then outstanding voting stock, voting together as a single class, shall be required to amend, alter or repeal, or adopt any provisions inconsistent with, Articles II (Meetings of Stockholders), III (Directors), VIII (Indemnification of Directors, Officers, Employees & Agents) or IX (Amendments) of our Bylaws.

Our Articles of Incorporation also require the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the shares of our then outstanding voting stock, voting together as a single class, to amend or repeal, or adopt any provisions inconsistent with, Articles VI (Action by Stockholders), VII (Number, Classification and Election of Directors; Vacancies), VIII (Removal of Directors), IX (Indemnification of Officers and Directors), XI (Control Share Acquisitions), XII (Business Combinations with Interested Stockholders), XIII (Amendment of Bylaws), or XIV (Amendment of Articles) of our Articles of Incorporation.

11

No Preemptive or Similar Rights

Our Class A Common Stock has no preemptive rights and is not entitled to the benefits of any redemption or sinking fund provision.

Dividend Rights

To the extent permitted under Kansas law and subject to the rights of holders of any outstanding shares of our preferred stock, holders of our Class A Common Stock are entitled to participate ratably on a per share basis with holders of our Class B Common Stock in the payment of dividends, when, as and if declared thereon by our board of directors. If we issue preferred stock, the holders of the preferred stock may have a priority over the holders of Class A Common Stock with respect to dividends.

Liquidation Rights

Subject to the provisions of any outstanding series of preferred stock and after payment of all of our debts and other liabilities, the holders of Class A Common Stock are entitled to participate ratably on a per share basis in all distributions to the holders of our Class A Common Stock and Class B Common Stock in any liquidation, dissolution or winding up of the Company.

Certain Provisions in Our Articles of Incorporation and Bylaws

Advance Notice for Stockholders Proposals and Director Nominations

Our Articles of Incorporation contain provisions requiring that advance notice be delivered to us of any business to be brought by a stockholder before an annual meeting of stockholders and provide for certain procedures to be followed by stockholders in nominating candidates for election as directors. Generally, the advance notice provisions require that stockholder proposals be provided to us no less than 120 days prior to the day corresponding to the date on which we released our proxy statement in connection with the previous year’s annual meeting in order to be properly brought before a stockholder meeting. The notice must set forth specific information regarding the stockholder submitting the proposal or nomination and the proposal or director nominee, as described in our Articles of Incorporation, and must otherwise comply with the terms of our Articles of Incorporation. These requirements are in addition to those set forth in the regulations adopted by the Securities and Exchange Commission under the Exchange Act.

Special Meetings of Stockholders

Our Articles of Incorporation provide that special meetings of stockholders may be called by our President, or by or at the direction of a majority of the board of directors, and shall be called by the Chairman of the board of directors, the President or the Secretary upon the written request of the holders of not less than twenty percent (20%) of all of the outstanding shares of our capital stock entitled to vote at such special meeting. The business transacted at a special meeting of stockholders shall be limited to that stated in the notice of such meeting or in a duly executed waiver thereof.

Potential Anti-Takeover Effect

Certain provisions of our Articles of Incorporation and Bylaws could make the acquisition of control of our Company and/or the removal of our existing management or directors more difficult, including those that:

• empower our board of directors, without stockholder approval, to issue our preferred stock, the terms of which, including voting power, are set by our board of directors;

• only permit stockholder action to be taken at an annual or special meeting of stockholders and not by written consent in lieu of such a meeting;

12

• provide for a classified board of directors, so that only approximately one-third of or directors are elected each year;

• require the affirmative vote of the holders of record of outstanding shares representing at least 66 2/3% of the voting power of all the shares of our capital stock then entitled to vote generally in the election of directors, voting together as a single class, to remove any of our directors;

• prohibit us from engaging in certain business combinations with “interested stockholders” (generally defined as a holder of 15% or more of our outstanding voting stock);

• require at least 120 days’ advance notice of nominations for the election of directors and the presentation of stockholder proposals at meetings of stockholders; and

• require prior regulatory application and approval of any transaction involving acquiring control of our organization.

These provisions are expected to discourage coercive takeover practices and inadequate takeover bids. They are also designed, in part, to encourage persons seeking to acquire control of the Company to first negotiate with our board of directors. We believe that the benefits of increased protection give us the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us and that these benefits outweigh the disadvantages of discouraging the proposals. Negotiating with the proponent could result in an improvement of the terms of the proposal.

SELLING STOCKHOLDER

Class A Common Stock

The Selling Stockholder (including its donees, pledgees, transferees or other successors-in-interest) identified below may offer to sell from time to time in the future up to an aggregate 1,729,783 shares of our Class A Common Stock, registered for resale by the Selling Stockholder, subject to any appropriate adjustment as a result of any stock dividend, stock split or distribution, or in connection with a combination of shares, and any security into which such shares of Class A Common Stock shall have been converted or exchanged in connection with a recapitalization, reorganization, reclassification, merger, consolidation, exchange, distribution or otherwise. The shares of Class A Common Stock consist of outstanding shares of our Class A Common Stock issued to the Selling Stockholder as partial merger consideration for our merger with NBC. We are registering the offering by the Selling Stockholder of the shares of Class A Common Stock described below pursuant to the provisions of the Registration Rights Agreement entered into in connection with such Merger.

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to such securities. Except as otherwise indicated, all persons listed below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws.

The following table sets forth information as of August 11, 2025 provided by the Selling Stockholder on or prior to such date regarding (i) the beneficial ownership of shares of our Class A Common Stock and (ii) the number of shares of our Class A Common Stock that may from time to time be offered or sold pursuant to this prospectus or any applicable prospectus supplement, amendment or free writing prospectus. The percentage of combined voting power prior to, and after, the offering is based on 19,218,036 shares of our Class A Common Stock issued and outstanding and 1,729,783 shares of Class A Common Stock held by the Selling Stockholder as of July 31, 2025. Information in the table below with respect to beneficial ownership has been furnished by the Selling Stockholder.

We have not sought to verify the information provided by the Selling Stockholder. The Selling Stockholder may hold or acquire at any time shares of Class A Common Stock in addition to those offered by this prospectus and may have acquired additional shares of Class A Common Stock since the date on which the information reflected herein was provided to us.

We will supplement or amend this prospectus as required to include any additional Selling Stockholder upon provision of all required information to us and subject to the terms of any relevant agreement between us and the Selling Stockholder.

The Selling Stockholder will determine when and how it sells the shares of Class A Common Stock offered in this prospectus, as described in the Plan of Distribution included in this prospectus. The Selling Stockholder is not obligated to sell any of the shares of our Class A Common Stock offered by this prospectus. The Selling Stockholder may sell, transfer or otherwise dispose of, at any time and from time to time, its shares of our Class A Common Stock pursuant to the Plan of Distribution included in this prospectus, including in registered offerings contemplated by the Registration Rights Agreement, or pursuant to an exemption, if available, from the registration requirements of the Securities Act, in each case after the date on which it provided the information set forth in the table below. See “Plan of Distribution” for additional information. For purposes of the following table, we have assumed that the Selling Stockholder will sell all of the shares of our Class A Common Stock beneficially owned by it that are covered by this prospectus.

Following the Closing, the Company and the Bank appointed C. Kendric Fergeson to the Board of Directors of the Company and the Board of Directors of the Bank.

We are registering the offering by the Selling Stockholder of the shares of Class A Common Stock held by the Selling Stockholder pursuant to the provisions of the Registration Rights Agreement. Pursuant to the terms of the Registration Rights Agreement, we will bear all costs, fees and expenses incurred in effecting the registration of the Securities covered by this prospectus.

PLAN OF DISTRIBUTION

We are registering the offer and sale from time to time by the Selling Stockholders (including its donees, pledgees, transferees or other successors-in-interest) of up to 1,729,783 shares of Class A Common Stock.

We will not receive any of the proceeds from the sale of Class A Common Stock by the Selling Stockholder. The aggregate proceeds to the Selling Stockholder will be the purchase price of the securities less any discounts and commissions borne by the Selling Stockholder.

Sales of the Class A Common Stock by the Selling Stockholder (including its donees, pledgees, transferees or other successors-in-interest) may from time to time be offered for sale either directly by such person, or through underwriters, dealers or agents or on any exchange on which the Class A Common Stock may from time to time be traded, in the over-the-counter market, or in independently negotiated transactions or otherwise. The methods by which the Class A Common Stock may be sold by the Selling Stockholder include:

• sales on NYSE or any national securities exchange or quotation service on which our Class A Common Stock may be listed or quoted at the time of sale;

• privately negotiated transactions;

• through one or more underwritten offerings on a firm commitment or best efforts basis;

• to or through underwriters, brokers, dealers or agents;

• exchange distributions and/or secondary distributions;

• sales in the over-the-counter market;

• “at the market” or through market makers or into an existing market for the securities;

• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

• broker-dealers may agree with the Selling Stockholder to sell a specified number of such shares at a stipulated price per share;

• block trades (which may involve crosses) in which the broker or dealer so engaged will attempt to sell the Class A Common Stock as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• purchases by a broker or dealer as principal and resale by such broker or dealer for its own account;

• settlement of short sales entered into after the date of this prospectus (including short sales “against the box”);

• through the writing or settlement of options or other hedging transactions, whether or not the options are listed on an options exchange;

• through the distributions of the shares by any Selling Stockholder to its general or limited partners, members, managers, affiliates, employees, directors or stockholders;

• a combination of any such methods of sale; and

• any other method permitted pursuant to applicable law.

The Selling Stockholder may elect to make an in-kind distribution of its shares of Class A Common Stock to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. To the extent that such members, partners or stockholders are not affiliates of ours, such members, partners or stockholders would thereby receive freely tradeable shares of our Class A Common Stock pursuant to the distribution through this registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

17

The Selling Stockholder may also sell shares of Class A Common Stock under Rule 144 or any other exemption from registration under the Securities Act, in each case if available, rather than under this prospectus.

The Selling Stockholder also may transfer its shares of Class A Common Stock in other circumstances, in which case the transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

Such transactions may be effected by the Selling Stockholder at fixed prices, market prices prevailing at the time of sale, at varying prices determined at the time or sale or at negotiated prices. Underwriters or broker-dealers may receive compensation in the form of discounts or commissions from the Selling Stockholder and may receive commissions from the purchasers of the securities for whom they may act as agent. The Selling Stockholder may agree to indemnify any underwriter, broker-dealer or agent that participates in transactions involving sales of the Class A Common Stock against certain liabilities, including liabilities arising under the Securities Act. We have agreed to register the Class A Common Stock for sale under the Securities Act and to indemnify the Selling Stockholder and each person who participates as an underwriter in the offering of the Class A Common Stock against certain civil liabilities, including certain liabilities under the Securities Act.

In connection with sales of Class A Common Stock under this prospectus, the Selling Stockholder may enter into hedging transactions with broker-dealers or other financial institutions, who may in turn engage in short sales of the Class A Common Stock in the course of hedging the positions they assume. The Selling Stockholder also may sell shares of Class A Common Stock short and deliver them to close their short positions, or loan or pledge the securities to broker-dealers that in turn may sell them. The Selling Stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholder will act independently of us in making decisions with respect to the price, timing, manner and size of each sale of securities. Offers to purchase securities may be solicited directly by the Selling Stockholder and the sale thereof may be made by the Selling Stockholder directly to institutional investors or others. In such a case, no underwriters or agents would be involved. The Selling Stockholder may use electronic media, including the Internet, to sell offered securities directly. The Selling Stockholder may offer the securities covered by this prospectus into an existing trading market on the terms described herein or in any applicable prospectus supplement, amendment or free writing prospectus relating thereto. If the Selling Stockholder utilize a dealer in the sale of the securities in respect of which this prospectus is delivered, the Selling Stockholder may sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by the dealer at the time of resale.

The Selling Stockholder may from time to time pledge or grant a security interest in some or all of the shares of Class A Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell shares of Class A Common Stock from time to time under this prospectus, or under an amendment to this prospectus under Rule 424 or other applicable provision of the Securities Act amending the list of Selling Stockholder to include the pledgee, transferee or other successors in interest as Selling Stockholder under this prospectus.

If the Selling Stockholder use one or more underwriters in the sale, the underwriters will acquire the securities for their own account, and they may resell these securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be offered and sold to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of such firms. Underwriters may resell the shares to or through dealers, and those dealers may receive compensation in the form of one or more discounts, concessions or commissions from the underwriters and commissions from purchasers for which they may act as

18

agents. We have not, and to our knowledge, the Selling Stockholder has not, entered into any agreement or understanding, directly or indirectly, with any person to distribute the securities offered hereby.

We are required to pay all fees and expenses incident to the registration of our securities. We have also agreed to keep the registration statement of which this prospectus forms a part or, if not available, another registration statement, effective until all of the registrable securities have ceased to be registrable securities under the Registration Rights Agreement or the termination of the Registration Rights Agreement has occurred.

There can be no assurances that the Selling Stockholder will sell, nor is the Selling Stockholder required to sell, any or all of the shares of Class A Common Stock offered under this prospectus or any applicable prospectus supplement, amendment or free writing prospectus.

To the extent required, this prospectus may be amended and/or supplemented from time to time to describe a specific plan of distribution. If required, we may add transferees, successors and donees by prospectus supplement in instances where the transferee, successor or donee has acquired its shares from holders named in this prospectus after the effective date of this prospectus. Transferees, successors and donees of identified Selling Stockholder may not be able to use this prospectus for resales until they are named in the Selling Stockholder table by prospectus supplement or post-effective amendment. See “Selling Stockholder.”

Item 15. Indemnification of Directors and Officers

Section 17-6305 of the Kansas General Corporation Code provides that a corporation has the power to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorney fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. Similarly, a Kansas corporation may also indemnify any person described in the previous sentence who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action or suit by or in the right of the corporation, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, except that any person found liable to the corporation may be indemnified only if a court has determined such person is fairly and reasonably entitled to indemnity for such expenses. To the extent that a present or former director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any foregoing action, suit or proceeding, or in defense of any claim, issue or matter therein, Section 17-6305 of the Kansas General Corporation Code provides that such director, officer, employee or agent will be indemnified against expenses, including attorney fees, actually and reasonably incurred by such person in connection therewith.

Our Articles of Incorporation and Bylaws provide that we will indemnify each of our officers and directors to the fullest extent permitted by Kansas law and that any modification or repeal of our Articles of Incorporation or Bylaws will not adversely affect this indemnification right of our officers and directors with respect to any act or omission occurring prior to such modification or repeal. Our Bylaws further provide that any expenses (including attorneys’ fees) actually and reasonably incurred by our officers and directors in connection with their defense of any indemnifiable proceeding or the enforcement of their indemnification rights will be paid by us in advance of the disposition of such action upon receipt of an undertaking by or on behalf of the officer or director to repay such amount if it is ultimately determined that they were not entitled to be indemnified.

As permitted by Section 17-6002(b)(8) of the Kansas General Corporation Code, our Articles of Incorporation eliminate a director’s liability to the Bank and the Bank’s stockholders for monetary damages for breach of a

II-1

fiduciary duty as a director, except for (a) any breach of the director’s duty of loyalty to the Bank or the Bank’s stockholders, (b) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) certain transactions under Section 17-6424 of the Kansas General Corporation Code (relating to liability for unauthorized acquisitions or redemptions of, or payment of dividends on, capital stock), or (d) for any transaction from which the director derived an improper personal benefit.

Our Bylaws also provide that the indemnification rights set forth in the Bylaws are not exclusive of other indemnification rights to which an indemnified party may be entitled under any statute, provision in our Articles of Incorporation or Bylaws, agreement, vote of stockholders or disinterested directors, policy of insurance or otherwise. In this regard, we have entered, or will enter, into indemnification agreements with each of our current and future directors and officers that will provide these individuals with a contractual right to indemnification from the Bank to the fullest extent permitted under Kansas law against any liability that may arise by reason of their service to us, and to the advancement of expenses incurred as a result of any proceeding against them as to which they could be indemnified. Our Bylaws further authorize us to purchase and maintain insurance on behalf of our officers and directors and we have obtained insurance to cover such individuals for certain liabilities.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Bank under any of the foregoing provisions, in the opinion of the SEC, that indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In addition, our ability to provide indemnification to our directors and officers is limited by federal banking laws and regulations, including, but not limited to, 12 U.S.C. §1828(k).

Item 17. Undertakings

(a) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referenced in Item 15 of this registration statement, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933, as amended (the “Securities Act”) and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered hereunder, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(b) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (b)(1)(i), (ii), and (iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is

part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications,

II-3

the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(5) That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6) That for purposes of determining any liability under the Securities Act:

(i) The information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(ii) Each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof
