Item 1.01 | Entry into a Material Definitive Agreement.

On August 26, 2024, First Busey Corporation, a Nevada corporation (“Busey”) and CrossFirst Bankshares, Inc., a Kansas corporation (“CrossFirst”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, CrossFirst will merge with and into Busey, with Busey as the surviving corporation in the merger (the “Merger”). The Merger Agreement further provides that at a date and time following the Merger as determined by Busey, CrossFirst Bank, a Kansas state-chartered bank and a wholly owned subsidiary of CrossFirst, will merge with and into Busey Bank, an Illinois state-chartered bank and a wholly owned subsidiary of Busey, with Busey Bank as the surviving bank (the “Bank Merger”). The Merger Agreement was unanimously approved by the Board of Directors of each of Busey and CrossFirst.

Merger Consideration

Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01 per share, of CrossFirst (“CrossFirst Common Stock”) outstanding immediately prior to the Effective Time, other than certain shares held by CrossFirst or Busey, will be converted into the right to receive 0.6675 of a share (the “Exchange Ratio”) of common stock, par value $0.001 per share, of Busey (“Busey Common Stock”). Holders of CrossFirst Common Stock will receive cash in lieu of fractional shares.

At the Effective Time, each share of Series A Non-Cumulative Perpetual Preferred Stock, par value $0.01 per share, of CrossFirst (“CrossFirst Preferred Stock”) outstanding immediately prior to the Effective Time will be converted into the right to receive one share of a newly created series of preferred stock of Busey, provided that at the election of Busey, Busey may cause the CrossFirst Preferred Stock to be converted in the Merger at the Effective Time into the right to receive an amount of cash equal to the liquidation preference thereof, plus the amount of any accrued and unpaid dividends thereon through the Effective Time.

Treatment of Busey’s Equity Awards

The Merger Agreement provides that, except as otherwise provided, Busey equity awards will generally remain outstanding and subject to the same terms and conditions as applied immediately prior to the Effective Time. Each outstanding Busey performance-based restricted stock unit award will be deemed earned with the achievement of the applicable performance goals based on actual performance through the latest practicable date prior to the Effective Time and will otherwise remain subject to the same terms and conditions (including service-based vesting terms) as applied to the Busey performance-based restricted stock unit awards immediately prior to the Effective Time. The Merger Agreement further provides that each outstanding Busey time-based restricted stock unit award (the “Busey RSUs”) will vest in equal annual installments over three (3) years following the Effective Time; provided that if any Busey RSU would otherwise vest by its terms on an earlier date, any then-unvested portion as of such date, shall vest on such original vesting date. Each Busey equity award will be subject to double-trigger vesting upon an involuntary termination within twelve (12) months following the Effective Time.

Treatment of CrossFirst’s Equity Awards

The Merger Agreement provides that each outstanding CrossFirst restricted stock award (“CrossFirst RSAs”) held by a CrossFirst non-employee director (the “CrossFirst Director RSAs”) and each deferred share of CrossFirst Common Stock that is credited to a director participant’s account under the CrossFirst 2018 Directors’ Deferred Fee Plan will be converted into the right to receive shares of Busey Common Stock. The Merger Agreement further provides that each CrossFirst RSA that is not a CrossFirst Director RSA (“CrossFirst Employee RSAs”) will be converted into a restricted stock award in respect of Busey Common Stock based on the Exchange Ratio, subject to the same terms and conditions as were applicable to the CrossFirst Employee RSA prior to the Effective Time. Each outstanding CrossFirst time-based restricted stock unit award (the “CrossFirst RSUs”) will be converted into a restricted stock unit in respect of Busey Common Stock (a “Busey RSU”) based on the Exchange Ratio, subject to the same terms and conditions as were applicable to the CrossFirst RSUs prior to the Effective Time, and each performance-based restricted stock unit award (the “CrossFirst PSUs”) will be converted into a Busey RSU based on the Exchange Ratio, subject to the same terms and conditions as were applicable to the CrossFirst PSUs prior to the Effective Time, assuming the achievement of the applicable performance goals at (i) target performance if the closing of the Merger occurs in the first half of the relevant performance period or (ii) actual performance if the closing of the Merger occurs in the second half of the relevant performance period. Each outstanding CrossFirst stock-settled stock appreciation right (the “CrossFirst SARs”) will be converted into a stock appreciation right in respect of Busey Common Stock based on the Exchange Ratio, subject to the same terms and conditions as were applicable to the CrossFirst SAR prior to the Effective Time.

Certain Governance Matters

The Merger Agreement provides that, prior to the Effective Time, the Board of Directors of Busey will take all actions necessary to adopt amendments to the Second Amended and Restated Bylaws of Busey regarding certain governance matters (the “Busey Bylaw Amendment”). Effective as of the Effective Time, and in accordance with the Merger Agreement and the Busey Bylaw Amendment, the number of directors that will comprise the full Board of Directors of Busey will be thirteen (13), of which (i) eight (8) will be directors of Busey or Busey Bank immediately prior to the Effective Time, which will include Van A. Dukeman, the current Executive Chairman and Chief Executive Officer of Busey and such other directors as determined by Busey and (ii) five (5) will be directors of CrossFirst immediately prior to the Effective Time, which will include Michael J. Maddox, the current President and Chief Executive Officer of CrossFirst and Rodney Brenneman, the current Chairman of the CrossFirst Board of Directors and such other directors as determined by CrossFirst.

Effective as of the Effective Time, (i) Mr. Dukeman will continue to serve as the Executive Chairman of the Board of Directors of Busey and as the Chief Executive Officer of Busey, reporting to the Board of Directors of Busey, and as the Executive Chairman of Busey Bank, reporting to the Board of Directors of Busey Bank and (ii) Mr. Maddox will serve as the Executive Vice Chairman of the Board of Directors of Busey and as the President of Busey reporting to the Chief Executive Officer of Busey, and as the Chief Executive Officer of Busey Bank, reporting to the Executive Chairman of the Board of Directors of Busey Bank.

Effective as of the date immediately following the earlier of (i) the twelve (12) month anniversary of the Bank Merger and (ii) the eighteen (18) month anniversary of the Effective Time, (i) Mr. Dukeman will continue to serve as the Executive Chairman of the Board of Directors of Busey, reporting to the Board of Directors of Busey and as the Executive Chairman of the Board of Directors of Busey Bank, reporting to the Board of Directors of Busey Bank, and (ii) Mr. Maddox will serve as the Executive Vice Chairman of the Board of Directors of Busey and as the Chief Executive Officer and President of Busey, reporting to the Board of Directors of Busey, and as the Chief Executive Officer of Busey Bank, reporting to the Board of Directors of Busey Bank (collectively, the “Succession Plan”).

If during the Specified Period (as defined below) Mr. Dukeman is no longer serving as the Chief Executive Officer of Busey for any reason prior to the time at which Mr. Maddox would otherwise become the Chief Executive Officer of Busey, Mr. Maddox will succeed Mr. Dukeman as Chief Executive Officer of Busey.

Messrs. Dukeman and Maddox can only be removed from the leadership positions described above, have their reporting relationships modified or have their employment arrangements amended in a manner that is adverse to them with a majority vote of the entire Board of Directors of Busey.

The Busey Bylaw Amendment provides that the composition of the Board of Directors of Busey Bank will be identical to that of the Board of Directors of Busey.

The Busey Bylaw Amendment addresses certain other governance matters, including (i) that Mr. Brenneman will serve as the Lead Independent Director of the Busey Board of Directors for two years following the Effective Time and (ii) matters related to the committees of the Busey Board of Directors and the composition of such committees.

-2-

The Merger Agreement and the Busey Bylaw Amendment provide that, following the Effective Time, the headquarters of the surviving corporation will be located in or near Kansas City, Missouri and the main office and legal headquarters of Busey Bank will remain in Champaign, Illinois.

The terms set forth in the Busey Bylaw Amendment will be applicable until the later of (i) the three (3) year anniversary of the Effective Time and (ii) the two (2) year anniversary of the date of the Bank Merger (the “Specified Period”). The terms set forth in the Busey Bylaw Amendment may only be amended with the vote of seventy-five percent (75%) of the entire Board of Directors of Busey.

In connection with the completion of the Merger, Busey will propose to amend its articles of incorporation to increase the number of authorized shares of Busey Common Stock from 100 million to 200 million (the “Busey Articles Amendment”).

Certain Other Terms and Conditions of the Merger Agreement

The Merger Agreement contains customary representations and warranties from both Busey and CrossFirst. CrossFirst has agreed to customary pre-closing covenants, including covenants to operate its business in the ordinary course in all material respects, to refrain from taking certain actions without Busey’s consent and to refrain from taking certain actions that may adversely affect its ability to consummate the transactions contemplated by the Merger Agreement on a timely basis without Busey’s consent. Busey has agreed to customary pre-closing covenants, including covenants to operate its business in the ordinary course in all material respects and to refrain from taking certain actions that may adversely affect its ability to consummate the transactions contemplated by the Merger Agreement on a timely basis without CrossFirst’s consent. Each party has agreed to additional covenants, including, among others, (i) in the case of Busey, its obligation to call a meeting of its stockholders to approve the Merger Agreement, the issuance of shares of Busey Common Stock pursuant to the Merger Agreement (the “Busey Share Issuance”) and the Busey Articles Amendment and, subject to certain exceptions, the obligation of the Busey Board of Directors to recommend that its stockholders approve the Merger Agreement and the Busey Share Issuance, (ii) in the case of CrossFirst, its obligation to call a meeting of its stockholders to approve the Merger Agreement, and, subject to certain exceptions, the obligation of the CrossFirst Board of Directors to recommend that its stockholders approve the Merger Agreement and (iii) each party’s non-solicitation obligations related to alternative acquisition proposals.

In addition, Busey Bank will apply to become a member of the Federal Reserve System.

The completion of the Merger is subject to customary conditions, including (i) approval of the Merger Agreement and the Busey Share Issuance by the requisite vote of the holders of Busey Common Stock, (ii) approval of the Merger Agreement by the requisite vote of the holders of CrossFirst Common Stock, (iii) authorization for listing on NASDAQ of the shares of Busey Common Stock to be issued in the Merger, subject to official notice of issuance, (iv) approval of the Board of Governors of the Federal Reserve System for the Merger and the Bank Merger and Busey Bank’s application to become a member of the Federal Reserve System, the Illinois Department of Financial and Professional Regulation for the Bank Merger and the Kansas Office of the State Bank Commissioner for the Merger, without the imposition of any condition or restriction that would be reasonably expected to have a material adverse effect on the surviving corporation and its subsidiaries, taken as a whole, after giving effect to the transactions contemplated by the Merger Agreement, (v) effectiveness of the registration statement on Form S-4 for the Busey Common Stock to be issued in the Merger and (vi) the absence of any order, injunction, decree or other legal restraint preventing the completion of the Merger, the Bank Merger or any of the other transactions contemplated by the Merger Agreement or making the completion of the Merger, the Bank Merger or any of the other transactions contemplated by the Merger Agreement illegal.

-3-

The Merger Agreement provides certain termination rights for both Busey and CrossFirst and further provides that a termination fee of $36.7 million will be payable by either Busey or CrossFirst, as applicable, upon termination of the Merger Agreement under certain circumstances.

The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of the parties to, the Merger Agreement and 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 standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties (i) will not survive consummation of the Merger and (ii) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding Busey or CrossFirst, their respective affiliates or their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding Busey, CrossFirst, their respective affiliates or their respective businesses, the Merger Agreement, the Merger and the Bank Merger 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 Busey and CrossFirst and a prospectus of CrossFirst, as well as in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings that each of Busey and CrossFirst makes with the Securities and Exchange Commission (“SEC”).

The foregoing description of the Merger Agreement (including the Busey Bylaw Amendment appended as an exhibit thereto) does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement (including the Busey Bylaw Amendment appended as an exhibit thereto), which is attached hereto as Exhibit 2.1 and incorporated herein by reference.

Item 5.02. | Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

In connection with the execution of the Merger Agreement, Busey entered into a letter agreement with Mr. Dukeman (the “Dukeman Letter Agreement”). Except as provided therein, the Dukeman Letter Agreement does not amend or change Mr. Dukeman’s existing employment agreement. In the event that the Merger is not completed, the Dukeman Letter Agreement will be void ab initio.

The Dukeman Letter Agreement provides that following the Effective Time and through the end of the Specified Period, Mr. Dukeman will receive base salary, annual bonus and long-term incentive awards that are no less than those paid to Mr. Maddox. Pursuant to the Dukeman Letter Agreement, Mr. Dukeman agrees that the Succession Plan will not give rise to a constructive discharge (as defined in Mr. Dukeman’s employment agreement). This waiver means that Mr. Dukeman will not be entitled to severance compensation as a result of the corporate governance changes effected in connection with the Merger.

The Dukeman Letter Agreement provides that Busey will terminate Mr. Dukeman’s right to severance pursuant to his employment agreement in compliance with Section 409A of the Internal Revenue Code’s change in control plan termination rules. Accordingly, the cash severance that would have been payable to Mr. Dukeman upon a qualifying termination under Mr. Dukeman’s employment agreement will be paid in a lump-sum on the one-year anniversary of the closing of the Merger, subject to his continued employment (other than in the event of a qualifying termination) (the “Dukeman Retention Payment”). In the event that Mr. Dukeman is terminated for cause or resigns other than due to constructive discharge (in each case, as defined in his employment agreement), (i) between the payment date of the Dukeman Retention Payment and the two-year anniversary of the closing of the Merger, Mr. Dukeman will promptly repay two-thirds of the Dukeman Retention Payment or (ii) between the two-year and three-year anniversaries of the closing of the Merger, Mr. Dukeman will promptly repay one-third of the Dukeman Retention Payment.

-4-

Pursuant to the Dukeman Letter Agreement, in the event that (i) the Succession Plan does not occur and Mr. Dukeman resigns in accordance with his constructive discharge rights or (ii) Mr. Dukeman’s employment is terminated without cause or Mr. Dukeman resigns in accordance with his constructive discharge rights (each such termination, a “qualifying termination”), Mr. Dukeman will be entitled to (a) any annual bonus or long-term incentive award earned or accrued but not yet paid, (b) the greater of (1) an amount equal to the sum of (x) his then applicable base salary through the remainder of the Specified Period and (y) annual performance bonuses (based on his then most recent annual performance bonus) that would have been earned or accrued during the remainder of the Specified Period and (2) an amount equal to the sum of his then applicable annual base salary and then most recent annual performance bonus, (c) payment for the value of the contributions that would have been made to Mr. Dukeman under all applicable retirement and other employee benefit plans had his employment continued through December 31 of the year in which such termination of employment occurs and (d) continuing coverage under all existing life, health and disability programs for one year following his termination date.

Mr. Dukeman’s outstanding equity awards will be treated in accordance with the Merger Agreement. In the event that Mr. Dukeman experiences a qualifying termination prior to the end of the Specified Period, the Dukeman Letter Agreement provides that (i) all outstanding time-based equity awards will vest and settle at the earliest time permitted without triggering a tax or penalty under Section 409A of the Internal Revenue Code and (ii) the service condition with respect to his outstanding performance-based equity awards will be waived and such awards will remain outstanding and eligible to vest based on achievement of the relevant performance metrics at the end of the applicable performance period.

Pursuant to the Dukeman Letter Agreement, Mr. Dukeman will be subject to a non-competition covenant (in addition to his existing restrictive covenants) until the later of (i) one (1) year following a termination of employment and (ii) the end of the Specified Period.

The Dukeman Letter Agreement provides that following the closing of the Merger, Mr. Dukeman will no longer be entitled to the excise tax gross-up set forth in his employment agreement.

The foregoing description of the Dukeman Letter Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Dukeman Letter Agreement, which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.

Item 8.01. | Other Events.

In connection with the execution of the Merger Agreement, Busey entered into a letter agreement with Mr. Maddox (the “Maddox Letter Agreement”). Except as provided therein, the Maddox Letter Agreement does not amend or change Mr. Maddox’s existing employment agreement. In the event that the Merger is not completed, the Maddox Letter Agreement will be void ab initio.

The Maddox Letter Agreement provides that following the Effective Time and through the end of the Specified Period, Mr. Maddox will receive base salary, annual bonus and long-term incentive awards that are no less than those paid to Mr. Dukeman. Pursuant to the Maddox Letter Agreement, Mr. Maddox agrees that the Succession Plan will not give rise to a constructive termination (as defined in the CrossFirst Senior Executive Severance Plan (the “CrossFirst Severance Plan”)). This waiver means that Mr. Maddox will not be entitled to severance compensation as a result of the corporate governance changes effected in connection with the Merger.

The Maddox Letter Agreement provides that Mr. Maddox’s right to severance pursuant to his employment agreement and the CrossFirst Severance Plan will be terminated. Accordingly, the cash severance that would have been payable to Mr. Maddox upon a qualifying termination under the CrossFirst Severance Plan will be converted into a cash retention award, which will be paid in equal annual installments on each of the three anniversaries of the closing of the Merger, subject to his continued employment or an earlier qualifying termination.

-5-

Pursuant to the Maddox Letter Agreement, in the event that (i) the Succession Plan does not occur and Mr. Maddox resigns in accordance with his constructive termination rights or (ii) Mr. Maddox’s employment is terminated without cause or he resigns in accordance with his constructive termination rights (each such termination, a “qualifying termination”), Mr. Maddox will be entitled to (a) any annual bonus or long-term incentive award earned or accrued but not yet paid, (b) the greater of (1) an amount equal to the sum of (x) his then applicable base salary through the remainder of the Specified Period, and (y) annual bonuses (based on target bonus for the year in which the qualifying termination occurs) that would have been earned or accrued during the remainder of the Specified Period and (2) an amount equal to two times the sum of his then applicable annual base salary and target annual bonus for the year in which the qualifying termination occurs, (c) the company-paid portion of the COBRA continuation premium to cover Mr. Maddox and his dependents enrolled under the company’s health, vision and dental plans in effect as of the termination date for 12 months and (d) reimbursement of up to $25,000 of reasonable expenses directly relating to outplacement counselling services obtained during the eighteen (18) month period following such termination date.

Mr. Maddox’s outstanding equity awards will be treated in accordance with the Merger Agreement. In the event that Mr. Maddox experiences a qualifying termination prior to the end of the Specified Period, the Maddox Letter Agreement provides that all outstanding equity awards will vest (with any performance-based vesting conditions deemed satisfied based on target performance) and settle at the earliest time permitted without triggering a tax or penalty under Section 409A of the Internal Revenue Code.

Pursuant to the Maddox Letter Agreement, Mr. Maddox will be subject to a non-competition covenant (in addition to his existing restrictive covenants) until the later of (i) one (1) year following a termination of employment and (ii) the end of the Specified Period.

The foregoing description of the Maddox Letter Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Maddox Letter Agreement, which is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

In connection with the execution of the Merger Agreement, Busey and CrossFirst issued a joint press release. A copy of the press release is attached hereto as Exhibit 99.2, which is incorporated herein by reference.

Forward-Looking Statements

This Current Report on Form 8-K and the exhibits filed therewith include “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, with respect to Busey’s and CrossFirst’s beliefs, goals, intentions, and expectations regarding the proposed transaction, revenues, earnings, loan production, asset quality, and capital levels, among other matters; our estimates of future costs and benefits of the actions we may take; our assessments of probable losses on loans; our assessments of interest rate and other market risks; our ability to achieve our financial and other strategic goals; the expected timing of completion of the proposed transaction; the expected cost savings, synergies and other anticipated benefits from the proposed transaction; and other statements that are not historical facts.

Forward-looking statements are typically identified by such words as “believe,” “expect,” “anticipate,” “plan,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “should,” “may,” “will,” “position,” and other similar words and expressions, and are subject to numerous assumptions, risks, and uncertainties, which change over time. These forward-looking statements include, without limitation, those relating to the terms, timing and closing of the proposed transaction.

Additionally, forward-looking statements speak only as of the date they are made; Busey and CrossFirst do not assume any duty, and do not undertake, to update such forward-looking statements, whether written or oral, that may be made from time to time, whether as a result of new information, future events, or otherwise. Furthermore, because forward-looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those indicated in such forward-looking statements as a result of a variety of factors, many of which are beyond the control of Busey and CrossFirst. Such statements are based upon the current beliefs and expectations of the management of Busey and CrossFirst and are subject to significant risks and uncertainties outside of the control of the parties. Caution should be exercised against placing undue reliance on forward-looking statements. The factors that could cause actual results to differ materially include the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the Merger Agreement; the outcome of any legal proceedings that may be instituted against Busey or CrossFirst; the possibility that the proposed transaction will not close when expected or at all because required regulatory, stockholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all, or are obtained subject to conditions that are not anticipated (and the risk that required regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction); the ability of Busey and CrossFirst to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of either or both parties to the proposed transaction; the possibility that the anticipated benefits of the proposed transaction will not be realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where Busey and CrossFirst do business; certain restrictions during the pendency of the proposed transaction that may impact the parties’ ability to pursue certain business opportunities or strategic transactions; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; the possibility that the parties may be unable to achieve expected synergies and operating efficiencies in the merger within the expected timeframes or at all and to successfully integrate CrossFirst’s operations and those of Busey; such integration may be more difficult, time consuming or costly than expected; revenues following the proposed transaction may be lower than expected; Busey’s and CrossFirst’s success in executing their respective business plans and strategies and managing the risks involved in the foregoing; the dilution caused by Busey’s issuance of additional shares of its capital stock in connection with the proposed transaction; effects of the announcement, pendency or completion of the proposed transaction on the ability of Busey and CrossFirst to retain customers and retain and hire key personnel and maintain relationships with their suppliers, and on their operating results and businesses generally; changes in interest rates and prepayment rates of Busey’s or CrossFirst’s assets fluctuations in the value of securities held in Busey’s or CrossFirst’s securities portfolio; concentrations within Busey’s or CrossFirst’s loan portfolio (including commercial real estate loans), large loans to certain borrowers, and large deposits from certain clients; the concentration of large deposits from certain clients who have balances above current FDIC insurance limits and may withdraw deposits to diversify their exposure; the level of non-performing assets on Busey’s or CrossFirst’s balance sheets; the strength of the local, state, national, and international economy; risks related to the potential impact of general economic, political and market factors or of exceptional weather occurrences such as tornadoes, hurricanes, floods, blizzards, droughts on the companies or the proposed transaction; the economic impact of any future terrorist threats or attacks, widespread disease or pandemics or other adverse external events that could cause economic deterioration or instability in credit markets; changes in state and federal laws, regulations, and governmental policies concerning Busey’s or CrossFirst’s general business; changes in accounting policies and practices; increased competition in the financial services sector (including from non-bank competitors such as credit unions and fintech companies) and the inability to attract new customers; breaches or failures of information security controls or cybersecurity-related incidents; changes in technology and the ability to develop and maintain secure and reliable electronic systems; the loss of key executives or associates; changes in consumer spending; unexpected outcomes of existing or new litigation, investigations, or inquiries involving Busey (including with respect to Busey’s Illinois franchise taxes) or CrossFirst; other factors that may affect future results of Busey and CrossFirst and the other factors discussed in the “Risk Factors” section of each of Busey’s and CrossFirst’s Annual Report on Form 10-K for the year ended December 31, 2023, in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of each of Busey’s and CrossFirst’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2024, and other reports Busey and CrossFirst file with the SEC.

AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of August 26, 2024 (this “Agreement”), by and between First Busey Corporation, a Nevada corporation (“Busey”), and CrossFirst Bankshares, Inc., a Kansas corporation (“CrossFirst”).

W I T N E S S E T H:

WHEREAS, the Boards of Directors of Busey and CrossFirst have determined that it is in the best interests of their respective companies and stockholders to consummate the strategic business combination transaction provided for herein, pursuant to which CrossFirst will, subject to the terms and conditions set forth herein, merge with and into Busey (the “Merger”), so that Busey is the surviving corporation (hereinafter sometimes referred to in such capacity as the “Surviving Corporation”) in the Merger;

WHEREAS, in furtherance thereof, the respective Boards of Directors of Busey and CrossFirst have approved the Merger and this Agreement;

WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement is intended to be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code;

WHEREAS, concurrently with the execution and delivery of this Agreement, the Chief Executive Officer of CrossFirst and the Chief Executive Officer of Busey each will enter into an employment arrangement with Busey, as the Surviving Corporation, which shall be effective as of the Effective Time; and

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

Article I

THE MERGER

1.1 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Nevada Revised Statutes (the “NRS”) and the Kansas General Corporation Code (the “KGCC”), at the Effective Time, CrossFirst shall merge with and into Busey. Busey shall be the Surviving Corporation in the Merger, and shall continue its corporate existence under the laws of the State of Nevada. Upon consummation of the Merger, the separate corporate existence of CrossFirst shall terminate.

1.2 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place by electronic exchange of documents at 9:00 a.m. Central Time, on the first business day of the month immediately following the month during which the satisfaction or waiver (subject to applicable law) of the latest to occur of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof) occurs (the date the last of the conditions set forth in Article VII hereof have been so satisfied or waived, the “Closing Conditions Satisfaction Date”), unless another date, time or place is agreed to in writing by the parties. Notwithstanding the foregoing, in the event the Closing Conditions Satisfaction Date is less than five (5) business days prior to the first business day of the month immediately following the month in which the Closing Conditions Satisfaction Date occurs, then Closing shall take place on the first business day of the month that is the second month following the month in which the Closing Conditions Satisfaction Date occurs. The date on which the Closing actually occurs is hereinafter referred to as the “Closing Date”.

1.3 Effective Time. The Merger shall become effective as set forth in the articles of merger to be filed with the Secretary of State of the State of Nevada (the “Nevada Secretary”) and the certificate of merger to be filed with the Secretary of State of the State of Kansas, respectively, on the Closing Date (together, the “Certificates of Merger”). The term “Effective Time” shall be the date and time when the Merger becomes effective, as set forth in the Certificates of Merger.

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the NRS and the KGCC.

1.5 Conversion of CrossFirst Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Busey, CrossFirst or the holder of any of the following securities:

(a) Subject to Section 2.2(e), each share of the common stock, par value $0.01 per share, of CrossFirst (the “CrossFirst Common Stock”) issued and outstanding immediately prior to the Effective Time, except for shares of CrossFirst Common Stock owned by CrossFirst as treasury stock or owned by CrossFirst or Busey (in each case other than shares of CrossFirst Common Stock (i) 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 or (ii) held, directly or indirectly, by CrossFirst or Busey in respect of debts previously contracted), shall be converted into the right to receive 0.6675 of a share (the “Exchange Ratio” and such shares, the “Merger Consideration”) of the common stock, par value $0.001, of Busey (the “Busey Common Stock”); it being understood that upon the Effective Time, pursuant to Section 1.8, the Busey Common Stock, including the shares issued to former holders of CrossFirst Common Stock, shall be the common stock of the Surviving Corporation.

-2-

(b) All of the shares of CrossFirst 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 (each, an “Old Share,” it being understood that any reference herein to an “Old Share” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of CrossFirst Common Stock) previously representing any such shares of CrossFirst Common Stock shall thereafter represent only the right to receive (i) a New Share representing the number of whole shares of Busey Common Stock which such shares of CrossFirst Common Stock have been converted into the right to receive, (ii) cash in lieu of fractional shares which the shares of CrossFirst Common Stock represented by such Old Share have been converted into the right to receive pursuant to this Section 1.5 and Section 2.2(e), without any interest thereon, and (iii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2, without any interest thereon. If, prior to the Effective Time, the outstanding shares of Busey Common Stock or CrossFirst 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, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio to give Busey and the holders of CrossFirst Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing contained in this sentence shall be construed to permit CrossFirst or Busey to take any action with respect to its securities or otherwise that is prohibited by the terms of this Agreement.

(c) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of CrossFirst Common Stock that are owned by CrossFirst or Busey (in each case other than shares of CrossFirst Common Stock (i) 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 or (ii) held, directly or indirectly, by CrossFirst or Busey in respect of debts previously contracted) shall be cancelled and shall cease to exist and no Busey Common Stock or other consideration shall be delivered in exchange therefor.

1.6 CrossFirst Preferred Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Busey, CrossFirst or the holder of any of the following securities, each share of Series A Non-Cumulative Perpetual Preferred Stock, par value $0.01, of CrossFirst (the “CrossFirst Preferred Stock”) issued and outstanding immediately prior to the Effective Time (other than the Dissenting Shares) shall be converted into the right to receive one share of a newly created series of preferred stock of Busey (all shares of such newly created series, collectively, the “New Busey Preferred Stock”) having rights, preferences, privileges, and powers (including a dividend of 8.00% per annum on the liquidation preference of $1,000 per share and voting powers), taken as a whole, as are not materially less favorable to the holders thereof than the rights, preferences, privileges, and powers (including voting powers) of the CrossFirst Preferred Stock, taken as a whole, provided, that the date upon which Busey may first redeem the New Busey Preferred Stock shall be at least five (5) years after the Effective Time, and, upon such conversion, the CrossFirst Preferred Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time; provided, further, that at the election of Busey, Busey may cause the CrossFirst Preferred Stock to be converted in the Merger at the Effective Time into the right to receive an amount of cash equal to the liquidation preference thereof plus the amount of any accrued and unpaid dividends thereon through the Effective Time.

-3-

1.7 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary and to the extent available under Section 17-6712 of the KGCC, any share of CrossFirst Preferred Stock that is issued and outstanding immediately prior to the Effective Time and that is held by a holder of CrossFirst Preferred Stock that complies with all of the provisions of the KGCC relevant to the exercise and perfection of appraisal rights (such share being a “Dissenting Share,” and such stockholder being a “Dissenting Stockholder”) shall not be converted into the right to receive New Busey Preferred Stock as set forth in Section 1.6 but rather shall be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Share pursuant to Section 17-6712 of the KGCC. If any Dissenting Stockholder fails to perfect such stockholder’s appraisal rights under the KGCC or effectively withdraws or otherwise loses such rights with respect to any Dissenting Shares, such Dissenting Shares shall thereupon automatically be converted into the right to receive New Busey Preferred Stock as set forth in Section 1.6, pursuant to the exchange procedures set forth in Section 2.2. Notwithstanding anything to the contrary contained in this Agreement, if the Merger is rescinded or abandoned, then the right of a holder of CrossFirst Preferred Stock to be paid the fair value of such holder’s Dissenting Shares pursuant to Section 17-6712 of the KGCC shall cease. CrossFirst shall give Busey (a) notice (and a copy) of any demand for payment of the fair value of any shares of CrossFirst Preferred Stock or any attempted withdrawal of any such demand for payment and any other instrument served pursuant to the KGCC and received by CrossFirst relating to any stockholder’s appraisal rights and (b) the opportunity to participate in all negotiations, communications and proceedings with respect to any such demands for payment under the KGCC. CrossFirst shall not voluntarily make any payment with respect to any demand for appraisal with respect to any Dissenting Shares without the prior written consent of Busey (which consent shall not be unreasonably conditioned, withheld or delayed).

1.8 Busey Stock. At and after the Effective Time, each share of Busey Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Corporation and shall not be affected by the Merger.

1.9 Treatment of CrossFirst Equity Awards; ESPP.

(a) Except as otherwise agreed between CrossFirst and Busey, at the Effective Time, each award in respect of shares of CrossFirst Common Stock subject to vesting, repurchase or other lapse restriction granted or assumed under the CrossFirst Stock Plan (a “CrossFirst Restricted Stock Award”) that is held by a non-employee director of CrossFirst and is outstanding, unvested and unsettled immediately prior to the Effective Time (a “CrossFirst Director Restricted Stock Award”) shall be converted into the right to receive shares of Busey Common Stock in accordance with Section 1.5(a). Each deferred share of CrossFirst Common Stock that is credited to a participant’s account under the CrossFirst 2018 Directors’ Deferred Fee Plan as of immediately prior to the Effective Time (“Director Deferred Shares”) shall be converted into the right to receive shares of Busey Common Stock in accordance with Section 1.5(a), which shares of Busey Common Stock shall be distributed to such participant as soon as administratively practicable following the Effective Time; provided that the number of shares of Busey Common Stock will be rounded to the nearest whole share.

(b) Except as otherwise agreed between CrossFirst and Busey, at the Effective Time, each CrossFirst Restricted Stock Award other than a CrossFirst Director Restricted Stock Award (a “CrossFirst Employee Restricted Stock Award”) that is outstanding, unvested and unsettled immediately prior to the Effective Time shall be assumed and converted into a restricted stock award in respect of Busey Common Stock subject to vesting, repurchase or other lapse restriction with the same terms and conditions as were applicable under such CrossFirst Employee Restricted Stock Award immediately prior to the Effective Time (including vesting terms and any “change in control” protections under the CrossFirst Stock Plan or award agreement), and relating to the number of shares of Busey Common Stock equal to the product of (i) the number of shares of CrossFirst Common Stock subject to such CrossFirst Restricted Stock Award immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio, with any fractional shares rounded to the nearest whole share of Busey Common Stock.

CrossFirst shall take all actions necessary to ensure that from and after the Effective Time neither Busey nor the Surviving Corporation will be required to deliver shares of CrossFirst Common Stock or other capital stock of CrossFirst to any person pursuant to or in settlement of CrossFirst Equity Awards.

(ii) “CrossFirst Stock Plan” means the CrossFirst Amended and Restated 2018 Omnibus Incentive Plan.

CrossFirst will terminate the CrossFirst ESPP as of no later than immediately prior to the Effective Time, pursuant to resolutions adopted by the Board of Directors of CrossFirst or the CrossFirst Compensation Committee, as applicable, copies of which shall be provided to Busey prior to the Closing and shall be subject to Busey’s reasonable review and comment.

(d) Except as otherwise agreed between CrossFirst and Busey, at the Effective Time, each performance-based restricted stock unit award in respect of shares of Busey Common Stock granted under a Busey Stock Plan that is outstanding, unvested and unsettled immediately prior to the Effective Time (a “Busey Performance Stock Unit Award”) that continues to remain outstanding will be deemed earned assuming the achievement of the applicable performance goals as of immediately prior to the Effective Time based on actual performance through the latest practicable date prior to the Effective Time as reasonably determined by the compensation committee of the Board of Directors of Busey consistent with past practice.

Article II

EXCHANGE OF SHARES

2.1 Busey to Make Merger Consideration Available. At or prior to the Effective Time, Busey shall deposit, or shall cause to be deposited, with an exchange agent designated by Busey and mutually acceptable to CrossFirst (the “Exchange Agent”), for the benefit of the holders of Old Shares (which for purposes of this Article II shall be deemed to also include certificates or book-entry account statements representing shares of CrossFirst Preferred Stock), for exchange in accordance with this Article II, (a) evidence of shares in book-entry form or, at Busey’s option, certificates (collectively, referred to herein as “New Shares”), representing the shares of Busey Common Stock or New Busey Preferred Stock to be issued to holders of CrossFirst Common Stock or CrossFirst Preferred Stock, as applicable, and (b) cash in lieu of any fractional shares (such cash and New Shares for shares of Busey Common Stock and New Busey Preferred Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”), to be issued pursuant to Section 1.5 and Section 1.6 and paid pursuant to Section 2.2(a).

2.2 Exchange of Shares.

(a) As promptly as practicable after the Effective Time, but in no event later than ten (10) business days thereafter, Busey and CrossFirst shall cause the Exchange Agent to mail to each holder of record of one or more Old Shares representing shares of CrossFirst Common Stock or CrossFirst Preferred Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive the Merger Consideration or shares of New Busey Preferred Stock, as applicable, pursuant to Article I, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Shares shall pass, only upon proper delivery of the Old Shares to the Exchange Agent) and instructions for use in effecting the surrender of the Old Shares in exchange for New Shares representing the number of whole shares of Busey Common Stock and any cash in lieu of fractional shares or shares of New Busey Preferred Stock, as applicable, which the shares of CrossFirst Common Stock or CrossFirst Preferred Stock represented by such Old Share or Old Shares shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b). Upon proper surrender of an Old Share or Old Shares for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Share or Old Shares shall be entitled to receive in exchange therefor, as applicable, (i) (A) New Shares representing that number of whole shares of Busey Common Stock to which such holder of CrossFirst Common Stock shall have become entitled pursuant to the provisions of Article I and (B) a check representing the amount of (1) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Share or Old Shares surrendered pursuant to the provisions of this Article II and (2) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), or (ii) (A) a New Share representing the number of shares of New Busey Preferred Stock to which such holder of CrossFirst Preferred Stock shall have become entitled pursuant to the provisions of Article I and (B) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Share or Old Shares so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares or dividends or distributions payable to holders of Old Shares. Until surrendered as contemplated by this Section 2.2, each Old Share shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the number of whole shares of Busey Common Stock or New Busey Preferred Stock which the shares of CrossFirst Common Stock or CrossFirst Preferred Stock, as applicable, represented by such Old Share have been converted into the right to receive and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.

-9-

(b) No dividends or other distributions declared with respect to Busey Common Stock or New Busey Preferred Stock shall be paid to the holder of any unsurrendered Old Share until the holder thereof shall surrender such Old Share in accordance with this Article II. After the surrender of an Old Share in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of Busey Common Stock or shares of New Busey Preferred Stock which the shares of CrossFirst Common Stock or CrossFirst Preferred Stock, as applicable, represented by such Old Share have been converted into the right to receive.

(c) If any New Share representing shares of Busey Common Stock or New Busey Preferred Stock is to be issued in a name other than that in which the Old Share or Old Shares surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Share or Old Shares so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a New Share representing shares of Busey Common Stock or New Busey Preferred Stock in any name other than that of the registered holder of the Old Share or Old Shares surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) After the Effective Time, there shall be no transfers on the stock transfer books of CrossFirst of the shares of CrossFirst Common Stock or CrossFirst Preferred Stock that were issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares). If, after the Effective Time, Old Shares representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for New Shares representing shares of Busey Common Stock or New Busey Preferred Stock, as applicable, as provided in this Article II.

(e) Notwithstanding anything to the contrary contained herein, no New Shares or scrip representing fractional shares of Busey Common Stock shall be issued upon the surrender for exchange of Old Shares, no dividend or distribution with respect to Busey Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Busey. In lieu of the issuance of any such fractional share, Busey shall pay to each former holder of CrossFirst Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of Busey Common Stock on NASDAQ as reported by The Wall Street Journal for the consecutive period of five (5) full trading days ending on the day preceding the Closing Date by (ii) the fraction of a share (after taking into account all shares of CrossFirst Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest thousandth when expressed in decimal form) of Busey Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.

-10-

(f) Any portion of the Exchange Fund that remains unclaimed by the holders of CrossFirst Common Stock and CrossFirst Preferred Stock for twelve (12) months after the Effective Time shall be paid to the Surviving Corporation. Any former holders of CrossFirst Common Stock and CrossFirst Preferred Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation for payment of the shares of Busey Common Stock and cash in lieu of any fractional shares or shares of New Busey Preferred Stock, as applicable, and any unpaid dividends and distributions on the Busey Common Stock or New Busey Preferred Stock deliverable in respect of each former share of CrossFirst Common Stock or CrossFirst Preferred Stock, as applicable, that such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Busey, CrossFirst, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of CrossFirst Common Stock or CrossFirst Preferred Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(g) Busey shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any cash in lieu of fractional shares of Busey Common Stock, any dividends or distributions payable pursuant to this Section 2.2 or any other consideration otherwise payable pursuant to this Agreement to any holder of CrossFirst Common Stock, CrossFirst Preferred Stock or CrossFirst Equity Awards such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of Tax law. To the extent that amounts are so withheld by Busey or the Exchange Agent, as the case may be, and paid over to the appropriate Governmental Entity, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of CrossFirst Common Stock, CrossFirst Preferred Stock or CrossFirst Equity Awards in respect of which the deduction and withholding was made by Busey or the Exchange Agent, as the case may be.

(h) In the event any Old Share shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the applicable certificate to be lost, stolen or destroyed and, if required by Busey or the Exchange Agent, the posting by such person of a bond in such amount as Busey 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 shares of Busey Common Stock and any cash in lieu of fractional shares, or the shares of New Busey Preferred Stock deliverable in respect thereof pursuant to this Agreement.

Article III

REPRESENTATIONS AND WARRANTIES OF CROSSFIRST

Except (a) as disclosed in the disclosure schedule delivered by CrossFirst to Busey concurrently herewith (the “CrossFirst Disclosure Schedule”); provided, that (i) 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, (ii) the mere inclusion of an item in the CrossFirst Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by CrossFirst that such item represents a material exception or fact, event or circumstance or that such item would reasonably be expected to result in a Material Adverse Effect, and (iii) any disclosures made with respect to a section of this Article III shall be deemed to qualify (A) any other section of this Article III specifically referenced or cross-referenced and (B) other sections of this 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 or (b) as disclosed in any CrossFirst Reports filed by CrossFirst after January 1, 2024 and prior to the date hereof (but disregarding risk factor disclosures contained under the heading “Risk Factors,” or disclosures of risks set forth in any “forward-looking statements” disclaimer or any other statements that are similarly nonspecific or cautionary, predictive or forward-looking in nature), and assuming each party’s compliance with its obligations set forth in Section 1.14, CrossFirst hereby represents and warrants to Busey as follows:

3.1 Corporate Organization.

(a) CrossFirst is a corporation duly organized, validly existing and in good standing under the laws of the State of Kansas and is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). CrossFirst has the corporate power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted. CrossFirst is duly licensed or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing, qualification or standing necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on CrossFirst. As used in this Agreement, “Material Adverse Effect” means, with respect to Busey, CrossFirst or the Surviving Corporation, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (i) the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, 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 U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, (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 and not specifically relating to such party or its Subsidiaries, (D) changes, after the date hereof, resulting from hurricanes, earthquakes, tornados, floods or other natural disasters or from any outbreak of any disease or other public health event, (E) public disclosure of the execution of this Agreement, public disclosure or consummation of the transactions contemplated hereby (including any effect on a party’s relationships with its customers or employees) or actions 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 (it being understood that this clause (E) shall not apply to a breach of any representation or warranty intended to address the announcement, pendency or consummation of the transactions contemplated hereby), (F) a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections or internal financial forecasts (it being understood that the underlying causes of such decline or failure may be taken into account in determining whether a Material Adverse Effect has occurred, except to the extent otherwise excepted by this proviso) or (G) the expenses incurred by CrossFirst or Busey in negotiating, documenting, effecting and consummating the transactions contemplated by this Agreement; except, with respect to subclauses (A), (B), (C) or (D) 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 in which such party and its Subsidiaries operate) or (ii) the ability of such party to timely consummate the transactions contemplated hereby. As used in this Agreement, “Subsidiary,” when used with respect to any person, means any subsidiary of such person within the meaning ascribed to such term in either Rule 1-02 of Regulation S-X promulgated by the SEC under the Exchange Act or the BHC Act; and “Significant Subsidiaries” shall have the meaning ascribed to it in Rule 1-02 of Regulation S-X promulgated by the SEC under the Exchange Act. True and complete copies of the Articles of Incorporation of CrossFirst (as amended, the “CrossFirst Certificate”) and the Bylaws of CrossFirst (the “CrossFirst Bylaws”), as in effect as of the date of this Agreement, have previously been made available by CrossFirst to Busey.

-12-

(b) Each Subsidiary of CrossFirst (a “CrossFirst Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership or leasing of property or the conduct of its business requires it to be so qualified and in which the failure to be so qualified would reasonably be expected to have a Material Adverse Effect on CrossFirst and (iii) has all requisite corporate power and authority to own or lease its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of any Subsidiary of CrossFirst to pay dividends or distributions except, in the case of a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all such regulated entities. The deposit accounts of each Subsidiary of CrossFirst that is an insured depository institution are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened.

There are no voting trusts, stockholder agreements, proxies or other agreements in effect to which CrossFirst is a party or is bound with respect to the voting or transfer of CrossFirst Common Stock or other equity interests of CrossFirst.

Since January 1, 2020, no independent public accounting firm of CrossFirst has resigned (or informed CrossFirst that it intends to resign) or been dismissed as independent public accountants of CrossFirst as a result of, or in connection with, any disagreements with CrossFirst on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

(b) Except as would not, either individually or in the aggregate, be material to CrossFirst and its Subsidiaries, taken as a whole, neither CrossFirst nor any of its Subsidiaries has any liability (whether absolute, accrued, contingent or otherwise and whether due or to become due), except for those liabilities that are reflected or reserved against on the consolidated balance sheet of CrossFirst included in its Annual and Quarterly Reports on Form 10-K and Form 10-Q for the fiscal year and quarter ended December 31, 2023 and June 30, 2024, respectively, (including any notes thereto) and for liabilities incurred in the ordinary course of business since December 31, 2023, or in connection with this Agreement and the transactions contemplated hereby.

There are no private letter ruling requests, closing agreements or gain recognition agreements with respect to Taxes requested or executed in the last six (6) years. Neither CrossFirst nor any of its Subsidiaries is a party to or is bound by any Tax sharing, Tax allocation or Tax indemnification agreement or arrangement (other than such an agreement or arrangement exclusively between or among CrossFirst and its Subsidiaries). Neither CrossFirst nor any of its Subsidiaries (i) has been a member of an affiliated group filing a consolidated federal income Tax Return (other than a group the common parent of which was CrossFirst) or (ii) has any liability for the Taxes of any person (other than CrossFirst or any of its Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign law), as a transferee or successor, by contract or otherwise. Neither CrossFirst nor any of its Subsidiaries has been, within the past two (2) years or otherwise as part of a “plan (or series of related transactions)” within the meaning of Section 355(e) of the Code of which the Merger is also a part, a “distributing corporation” or a “controlled corporation” (within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock intending to qualify for tax-free treatment under Section 355 of the Code. Neither CrossFirst nor any of its Subsidiaries has participated in a “reportable transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(1).

(e) Neither CrossFirst, any of its Subsidiaries nor any of their respective ERISA Affiliates has contributed (or had any obligation of any sort) in the last six (6) years to a plan that is subject to Section 412 of the Code or Section 302 or Title IV of ERISA. For purposes of this Agreement, “ERISA Affiliate” means, with respect to any entity, trade or business, any other entity, trade or business that is, or was at the relevant time, a member of a group described in Section 414(b), (c), (m) or (o) of the Code or Section 4001(b)(1) of ERISA that includes or included the first entity, trade or business, or that is, or was at the relevant time, a member of the same “controlled group” as the first entity, trade or business pursuant to Section 4001(a)(14) of ERISA.

(h) All contributions required to be made to any CrossFirst Benefit Plan by applicable law or by any plan document, and all premiums due or payable with respect to insurance policies funding any CrossFirst Benefit Plan, for any period through the date hereof, have been timely made or paid in full or, to the extent not required to be made or paid on or before the date hereof, have been fully reflected on the books and records of CrossFirst, except as, either individually or in the aggregate, would not reasonably be expected to result in any material liability to CrossFirst and its Subsidiaries.

Busey and CrossFirst 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 exchange of information, all the information relating to Busey and CrossFirst, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated hereby. Each party shall consult with the other in advance of any meeting or conference with any Governmental Entity in connection with the transactions contemplated by this Agreement and to the extent permitted by such Governmental Entity, give the other party and/or its counsel the opportunity to attend and participate in such meetings and conferences, in each case subject to applicable law. As used in this Agreement, “Requisite Regulatory Approvals” means all regulatory authorizations, consents, orders or approvals (and the expiration or termination of all statutory waiting periods in respect thereof) (i) from the Federal Reserve Board, the IDFPR and the KOSBC and (ii) set forth in Sections 3.4 and 4.4 that are necessary to consummate the transactions contemplated by this Agreement, including the Merger, the Bank Merger and FRS Membership, or those the failure of which to be obtained would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on the Surviving Corporation.

(c) Each party shall use its reasonable best efforts to resolve any objection that may be asserted by any Governmental Entity with respect to this Agreement or the transactions contemplated hereby. Notwithstanding the foregoing, nothing contained in this Agreement shall be deemed to require Busey and CrossFirst or any of their respective Subsidiaries, and neither Busey and CrossFirst nor any of their respective Subsidiaries shall be permitted (without the written consent of the other party), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of Governmental Entities or Regulatory Agencies that would reasonably be expected to have a material adverse effect on the Surviving Corporation and its Subsidiaries, taken as a whole, after giving effect to the Merger and the Bank Merger (a “Materially Burdensome Regulatory Condition”).

(d) To the extent permitted by applicable law, Busey and CrossFirst shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and stockholders, as applicable, and such other matters as may be reasonably necessary or advisable in connection with the Joint Proxy Statement, the S-4 or any other statement, filing, notice or application made by or on behalf of Busey, CrossFirst or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement.

-55-

(e) To the extent permitted by applicable law, Busey and CrossFirst shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval 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 will be materially delayed.

6.2 Access to Information; Confidentiality.

(a) Upon reasonable notice and subject to applicable laws, each of Busey and CrossFirst, for the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, shall, and shall cause each of their respective Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors and other representatives of the other party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments, personnel, information technology systems, and records, and each shall cooperate with the other party in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally, and, during such period, each of Busey and CrossFirst shall, and shall cause its respective Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws (other than reports or documents that Busey and CrossFirst, as the case may be, is not permitted to disclose under applicable law), and (ii) all other information concerning its business, properties and personnel as such party may reasonably request. Notwithstanding the foregoing, neither Busey and CrossFirst nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of Busey’s or CrossFirst’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Each of Busey and CrossFirst shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of the Mutual Confidentiality and Non-Disclosure Agreement, dated as of February 28, 2024, between Busey and CrossFirst (the “Confidentiality Agreement”).

(c) No investigation by either of the parties or their respective representatives shall affect or be deemed to modify or waive the representations and warranties of the other set forth herein. Nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time. Prior to the Effective Time, each party shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

-56-

6.3 Stockholder Approval.

(a) Each of Busey and CrossFirst shall call, give notice of, convene and hold a meeting of its respective stockholders (the “Busey Meeting” and the “CrossFirst Meeting,” respectively) to be held as soon as reasonably practicable after the S-4 is declared effective, for the purpose of obtaining (i) in the case of CrossFirst, the Requisite CrossFirst Vote and, in the case of Busey, the Requisite Busey Vote, respectively, required in connection with this Agreement and the Merger and also, in the case of Busey, the required stockholder vote to approve the Busey Articles Amendment (the “Busey Articles Amendment Vote”) and (ii) if so desired and mutually agreed, a vote upon other matters of the type customarily brought before a meeting of stockholders in connection with the approval of a merger agreement or the transactions contemplated thereby, and each of CrossFirst and Busey shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date and to set the same record date for such meetings. Such meetings may be held virtually, subject to applicable law and the organizational documents of each party.

(b) Subject to Section 6.3(c), each of Busey and CrossFirst and their respective Boards of Directors shall use its reasonable best efforts to obtain from the stockholders of Busey and CrossFirst, as applicable, the Requisite Busey Vote, the Busey Articles Amendment Vote and the Requisite CrossFirst Vote, as applicable, including by communicating to the respective stockholders its recommendation (and including such recommendation in the Joint Proxy Statement) that the stockholders of Busey and CrossFirst, respectively, adopt this Agreement (the “Busey Board Recommendation” and the “CrossFirst Board Recommendation,” respectively) and that the stockholders of Busey approve the Busey Articles Amendment. Each of Busey and CrossFirst and their respective Boards of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the Busey Board Recommendation, in the case of Busey, or the CrossFirst Board Recommendation, in the case of CrossFirst, (ii) fail to make the Busey Board Recommendation, in the case of Busey, or the CrossFirst Board Recommendation, in the case of CrossFirst, in the Joint Proxy Statement, (iii) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the Busey Board Recommendation, in the case of Busey, or the CrossFirst Board Recommendation, in the case of CrossFirst, in each case within ten (10) business days (or such fewer number of days as remains prior to the Busey Meeting or the CrossFirst Meeting, as applicable) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing, a “Recommendation Change”).

-57-

(c) Subject to Section 8.1 and Section 8.2, if the Board of Directors of Busey or CrossFirst, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the Busey Board Recommendation or the CrossFirst Board Recommendation, as applicable, such Board of Directors may, in the case of Busey, prior to the receipt of the Requisite Busey Vote, and in the case of CrossFirst, prior to the receipt of the Requisite CrossFirst Vote, submit this Agreement to its stockholders, without recommendation (which, for the avoidance of doubt, shall constitute a Recommendation Change) (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event such Board of Directors may communicate the basis for its lack of a recommendation to its stockholders, as applicable, in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided, that such Board of Directors may not take any actions under this sentence unless it (i) gives the other party at least three (3) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions of, and the identity of the third party making, any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (ii) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its outside financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the Busey Board Recommendation or CrossFirst Board Recommendation, as the case may be. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3(c) and will require a new notice period as referred to in this Section 6.3(c).

(d) Busey or CrossFirst shall adjourn or postpone the Busey Meeting or the CrossFirst Meeting, as the case may be, if, as of the time for which such meeting is originally scheduled there are insufficient shares of Busey Common Stock or CrossFirst Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting Busey or CrossFirst, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite Busey Vote or the Requisite CrossFirst Vote, and subject to the terms and conditions of this Agreement, Busey or CrossFirst, as applicable, shall continue to use reasonable best efforts to solicit proxies from its stockholders in order to obtain the Requisite Busey Vote or the Requisite CrossFirst Vote, respectively. Notwithstanding anything to the contrary herein, but subject to the obligation to adjourn or postpone such meeting as set forth in the immediately preceding sentence, unless this Agreement has been terminated in accordance with its terms, (i) the Busey Meeting shall be convened and this Agreement shall be submitted to the stockholders of Busey at the Busey Meeting and (ii) the CrossFirst Meeting shall be convened and this Agreement shall be submitted to the stockholders of CrossFirst at the CrossFirst Meeting, and nothing contained herein shall be deemed to relieve either Busey or CrossFirst of such obligation.

6.4 Legal Conditions to Merger. Subject in all respects to Section 6.1 of this Agreement, each of Busey and CrossFirst shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal and regulatory requirements that may be imposed on such party or its Subsidiaries with respect to the Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, including the Merger, the Bank Merger and the FRS Membership, and (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by Busey or CrossFirst or any of their respective Subsidiaries in connection with the Merger, the Bank Merger, the FRS Membership and the other transactions contemplated by this Agreement.

-58-

6.5 Stock Exchange Listing.

(a) Busey shall cause the shares of Busey Common Stock to be issued in the Merger to be approved for listing on NASDAQ, subject to official notice of issuance, prior to the Effective Time.

(b) Prior to the Closing Date, CrossFirst shall cooperate with Busey and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable laws and rules and policies of NASDAQ to enable the delisting by the Surviving Corporation of CrossFirst Common Stock from NASDAQ and the deregistration of CrossFirst Common Stock under the Exchange Act as promptly as practicable after the Effective Time.

6.6 Employee Matters.

(a) Busey, as the Surviving Corporation, shall provide the employees of CrossFirst and its Subsidiaries as of the Effective Time who remain employed with Busey or its Subsidiaries (the “Continuing Employees”), during the period commencing at the Effective Time and ending on the first anniversary of the Effective Time (the “Continuation Period”), with the following: (i) annual base salary or wages, as applicable, that are no less than the annual base salary or wages in effect for each such Continuing Employee immediately prior to the Effective Time; (ii) all employee statutory entitlements; and (iii) all employee benefits (other than severance which will be provided as set forth in the last sentence of this Section 6.6(a)) and other compensation that are substantially comparable in the aggregate to those provided to similarly situated employees of Busey and its Subsidiaries. Each Continuing Employee who is not party to an individual agreement providing for severance or termination benefits and is terminated during the Continuation Period, under severance qualifying circumstances shall be provided severance benefits as set forth in Section 6.6(a) of the CrossFirst Disclosure Schedule.

(b) With respect to any employee benefit plans of Busey or its Subsidiaries in which any Continuing Employees become eligible to participate on or after the Effective Time (the “New Plans”), Busey, as the Surviving Corporation, and its Subsidiaries shall (i) use commercially reasonable efforts to waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents under any New Plans, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous CrossFirst Benefit Plan, (ii) use commercially reasonable efforts to provide each such employee and their eligible dependents with credit for any co-payments or coinsurance and deductibles paid prior to the Effective Time under a CrossFirst Benefit Plan that provides health care benefits, to the same extent that such credit was given under the analogous CrossFirst Benefit Plan prior to the Effective Time, in satisfying any applicable deductible, co-payment, coinsurance or maximum out-of-pocket requirements under any New Plans, (iii) recognize all service of such employees with CrossFirst and its Subsidiaries for all purposes in any New Plan to the same extent that such service was taken into account under the analogous CrossFirst Benefit Plan prior to the Effective Time and (iv) honor any accrued paid time off, vacation or other approved leave; provided, that the foregoing service recognition shall not apply (A) to the extent it would result in duplication of benefits for the same period of service, (B) for purposes of any defined benefit pension plan, or (C) for purposes of any benefit plan that is a frozen plan or provides grandfathered benefits. CrossFirst will provide the information reasonably necessary for Busey to recognize annual co-payments, coinsurance, deductibles and out-of-pocket expenses in accordance with this Section 6.6(b) no later than fifteen (15) days prior to the Closing Date.

-59-

(c) If requested by Busey in writing at least fifteen (15) business days prior to the Effective Time, CrossFirst shall cause any 401(k) plan sponsored or maintained by CrossFirst and its Subsidiaries, including, without limitation, the CrossFirst 401(k) Plan (each, a “CrossFirst 401(k) Plan”) to be terminated effective as of the day immediately prior to the Effective Time and contingent upon the occurrence of the Closing. If Busey requests that any CrossFirst 401(k) Plan be terminated, (i) CrossFirst shall provide Busey with evidence that such plan has been terminated (the form and substance of which shall be subject to reasonable review and comment by Busey) not later than two (2) business days immediately preceding the Effective Time, and (ii) the Continuing Employees of CrossFirst shall be eligible to participate, effective as of the Effective Time or as soon as administratively practicable thereafter, in a 401(k) plan sponsored or maintained by Busey or one of its Subsidiaries (a “Busey 401(k) Plan”). Busey and CrossFirst shall take any and all actions as may be required, including amendments to any CrossFirst 401(k) Plan and/or Busey 401(k) Plan, to permit the Continuing Employees of CrossFirst who are then actively employed to make rollover contributions to the Busey 401(k) Plan of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) in the form of cash, notes (in the case of loans) or a combination thereof.

(d) Busey, as the Surviving Corporation, shall assume and honor all CrossFirst Benefit Plans in accordance with their terms. CrossFirst agrees that the transactions contemplated by this Agreement shall constitute a “change in control”, “change of control” or other similar concept under any CrossFirst Benefit Plan, and prior to the Effective Time, the CrossFirst Board of Directors or CrossFirst Compensation Committee shall be empowered to take such action as necessary to declare such status under such CrossFirst Benefit Plans.

(e) Nothing in this Agreement shall confer upon any employee, officer, director or consultant of CrossFirst, Busey or any of their respective Subsidiaries or affiliates any right to continue in the employ or service of the Surviving Corporation, CrossFirst, Busey or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Corporation, CrossFirst, Busey or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee (including any Continuing Employee), officer, director or consultant of the Surviving Corporation, CrossFirst, Busey or any of their respective Subsidiaries or affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any CrossFirst benefit plan, Busey benefit plan, New Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Corporation or any of its Subsidiaries or affiliates to amend, modify or terminate any particular CrossFirst benefit plan, Busey benefit plan, New Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of Section 9.11, nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including, without limitation, any current or former employee, officer, director or consultant of CrossFirst, Busey or any of their respective Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

-60-

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, the Surviving Corporation shall indemnify and hold harmless and shall advance expenses as incurred, in each case to the extent (subject to applicable law) such persons are indemnified or entitled to such advancement of expenses as of the date of this Agreement by CrossFirst pursuant to the CrossFirst Certificate, CrossFirst Bylaws, the governing or organizational documents of any Subsidiary of CrossFirst, any indemnification agreements in existence as of the date hereof that have been disclosed to Busey or the KGCC, each present and former director, officer or employee of CrossFirst and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “CrossFirst Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages, liabilities and other amounts incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of the fact that such person is or was a director, officer or employee of CrossFirst or any of its Subsidiaries and pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement; provided, that in the case of advancement of expenses, the CrossFirst Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such CrossFirst Indemnified Party is not entitled to indemnification.

(b) For a period of six (6) years after the Effective Time, the Surviving Corporation shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by CrossFirst (provided, that the Surviving Corporation may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the insured) with respect to claims against the present and former officers and directors of CrossFirst or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time; provided, that the Surviving Corporation shall not be obligated to expend, on an annual basis, an amount in excess of 250% of the current annual premium paid as of the date hereof by CrossFirst for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Corporation shall cause to be maintained policies of insurance which, in the Surviving Corporation’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, CrossFirst, in consultation with, but only upon the consent of Busey, may (and at the request of Busey, CrossFirst shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six (6)-year “tail” policy under CrossFirst’s existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap.

-61-

(c) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each CrossFirst Indemnified Party and his or her heirs and representatives. If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving person of such consolidation or merger, or (ii) transfers all or substantially all of its assets or deposits to any other person or engages in any similar transaction, then in each such case the Surviving Corporation will cause proper provision to be made so that the successors and assigns of the Surviving Corporation will expressly assume the obligations set forth in this Section 6.7.

6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of Busey, on the one hand, and a Subsidiary of CrossFirst, on the other) or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger or the Bank Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by Busey.

6.9 Advice of Changes. Busey and CrossFirst shall each promptly advise the other party of any effect, change, event, circumstance, condition, occurrence or development (a) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on it or (b) that it believes would or would reasonably be expected to cause or constitute a material breach of any of its representations, warranties, obligations, covenants or agreements contained herein that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.9 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 6.9 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice.

6.12 Acquisition Proposals.

(a) Each party agrees that it will not, and will cause each of its Subsidiaries and its and their respective officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any Acquisition Proposal or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (whether written or oral, binding or nonbinding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.12) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite CrossFirst Vote, in the case of CrossFirst, or the Requisite Busey Vote, in the case of Busey, a party receives an unsolicited bona fide written Acquisition Proposal, such party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Board of Directors of such party concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its outside financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, such party shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. Each party will, and will cause its Subsidiaries and Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than the other party with respect to any Acquisition Proposal. Each party will promptly (within twenty-four (24) hours) advise the other party following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the other party with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received from or on behalf of the person making such inquiry or Acquisition Proposal in connection with such inquiry or Acquisition Proposal, and will keep the other party apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Each party shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof. As used in this Agreement, “Acquisition Proposal” means, with respect to Busey or CrossFirst, as applicable, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third party indication of interest in, (A) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of a party and its Subsidiaries or 25% or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of the party, (B) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning 25% or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of the party, or (C) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving a party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of the party.

-64-

(b) Nothing contained in this Agreement shall prevent a party or its Board of Directors from complying with Rules 14d-9 and 14e-2 under the Exchange Act with respect to an Acquisition Proposal; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

6.13 Public Announcements. CrossFirst and Busey agree that the initial press release with respect to the execution and delivery of this Agreement shall be a release mutually agreed to by the parties. Thereafter, each of the parties agrees that no public release or announcement or statement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (a) as required by applicable law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on, such release or announcement in advance of such issuance or (b) for such releases, announcements or statements that are consistent with other such releases, announcement or statements made after the date of this Agreement in compliance with this Section 6.13.

6.14 Change of Method. CrossFirst and Busey shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the combination of CrossFirst and Busey (including the provisions of Article I), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided, that no such change shall (a) alter or change the Exchange Ratio or the number of shares of Busey Common Stock received by holders of CrossFirst Common Stock in exchange for each share of CrossFirst Common Stock, (b) adversely affect the Tax treatment of holders of CrossFirst Common Stock or Busey Common Stock pursuant to this Agreement, (c) adversely affect the Tax treatment of CrossFirst or Busey pursuant to this Agreement or (d) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 9.2.

6.15 Restructuring Efforts. If either CrossFirst or Busey shall have failed to obtain the Requisite CrossFirst Vote or the Requisite Busey Vote at the duly convened CrossFirst Meeting or Busey Meeting, as applicable, or any adjournment or postponement thereof, each of the parties shall in good faith use its reasonable best efforts to negotiate a restructuring of the transactions contemplated by this Agreement, including by merging CrossFirst into a newly created wholly owned subsidiary of Busey (it being understood that neither party shall have any obligation to alter or change any material terms, including the Exchange Ratio or the amount or kind of the consideration to be issued to holders of the capital stock of CrossFirst as provided for in this Agreement, in a manner adverse to such party or its stockholders) and/or resubmit this Agreement and/or the transactions contemplated hereby (or as restructured pursuant to this Section 6.15) to its stockholders for adoption or approval.

-65-

6.16 Takeover Statutes. None of CrossFirst, Busey or their respective Boards of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of its Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

6.17 Treatment of CrossFirst Debt. Upon the Effective Time (or at the effective time of the Bank Merger for any debt of CrossFirst Bank), Busey, or Busey Bank, as applicable, shall assume the due and punctual performance and observance of the covenants and other obligations to be performed by CrossFirst or CrossFirst Bank, as applicable, under the definitive documents governing the indebtedness and other instruments related thereto set forth on Section 6.17 of the CrossFirst Disclosure Schedule, including the due and punctual payment of the principal of (and premium, if any) and interest thereon, to the extent required and permitted thereby. In connection therewith, (a) Busey shall, and shall cause Busey Bank to, cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, if applicable, and (b) CrossFirst shall, and shall cause CrossFirst Bank to, cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, officer’s certificates or other documents and provide any opinions of counsel to the trustee thereof, in each case, required to make such assumption effective as of the Effective Time, or the effective time of the Bank Merger, as applicable.

6.18 Exemption from Liability under Section 16(b). Busey and CrossFirst agree that, in order to most effectively compensate and retain CrossFirst Section 16 Individuals, both prior to and after the Effective Time, it is desirable that CrossFirst Section 16 Individuals not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable law in connection with the conversion of shares of CrossFirst Common Stock, CrossFirst Preferred Stock and CrossFirst Equity Awards into Busey Common Stock, New Busey Preferred Stock or Busey Equity Awards, as applicable, in connection with the Merger, and for that compensatory and retentive purpose agree to the provisions of this Section 6.18. CrossFirst shall deliver to Busey in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of CrossFirst subject to the reporting requirements of Section 16(a) of the Exchange Act (the “CrossFirst Section 16 Individuals”), and the Board of Directors of Busey and of CrossFirst, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, take all such steps as may be required to cause (in the case of CrossFirst) any dispositions of CrossFirst Common Stock, CrossFirst Preferred Stock or CrossFirst Equity Awards by the CrossFirst Section 16 Individuals, and (in the case of Busey) any acquisitions of Busey Common Stock, New Busey Preferred Stock, or Busey Equity Awards by any CrossFirst Section 16 Individuals who, immediately following the Merger, will be officers or directors of the Surviving Corporation subject to the reporting requirements of Section 16(a) of the Exchange Act, in each case pursuant to the transactions contemplated by this Agreement, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable law.

(e) Each of Busey and CrossFirst acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if Busey or CrossFirst, as the case may be, fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit that results in a judgment against the non-paying party for the Termination Fee or any portion thereof, such non-paying party shall pay the costs and expenses of the other party (including reasonable attorneys’ fees and expenses) in connection with such suit. In addition, if Busey or CrossFirst, as the case may be, fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts (for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full) at a rate per annum equal to the “prime rate” published in “The Wall Street Journal” on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full. The amounts payable by Busey and CrossFirst pursuant to Sections 8.2(b) and 8.2(c), respectively, and this Section 8.2(e), constitute liquidated damages and not a penalty, and except in the case of fraud or willful and material breach, shall be the sole monetary remedy of the other party in the event of a termination of this Agreement specified in such applicable section.

Exhibit 10.1

[LETTERHEAD OF FIRST BUSEY CORPORATION]

August 26, 2024

Van A. Dukeman

At the address on file with the Corporation

Dear Van:

Reference is made to the Agreement and Plan of Merger, dated as of August 26, 2024, between First Busey Corporation (the “Corporation”) and CrossFirst Bankshares, Inc. (as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”) and your Employment Agreement, dated as of December 26, 2001, by and between you and the Corporation, as amended from time to time (your “Employment Agreement”). The effectiveness of the terms of this letter agreement shall be conditioned upon the Closing. Notwithstanding anything in this agreement to the contrary, in the event that the Merger Agreement terminates prior to Closing, this letter agreement shall be void ab initio. Capitalized terms used and not otherwise defined herein have the respective meanings ascribed to them in the Merger Agreement, except as otherwise noted.

As you are aware, the Merger Agreement contemplates that, as of the Closing Date, you will continue to serve as Executive Chairman of the Board of Directors of the Surviving Corporation (the “Board”) and as Chief Executive Officer of the Surviving Corporation, reporting to the Board, and will serve as Executive Chairman of the Board of Directors of Busey Bank (the “Bank Board”), reporting to the Bank Board, but you will no longer serve as Chief Executive Officer of Busey Bank. As of the earlier of (a) the 12-month anniversary of the closing of the Bank Merger and (b) the 18-month anniversary of the Effective Time, you will no longer serve as Chief Executive Officer of the Surviving Corporation but until the end of the Specified Period (as defined below), you will continue to serve as Executive Chairman of the Board, reporting to the Board, and as Executive Chairman of the Bank Board, reporting to the Bank Board. The roles described in this paragraph are referred to as the “Succession Plan.”

This letter agreement confirms to you, and you agree, that your Employment Agreement shall be amended as follows:

| 1. | Compensation. Following the Closing Date and through later of (x) the three-year anniversary of the Closing Date and (y) the two-year anniversary of the Bank Merger (the “Specified Period”), your base salary, annual bonus and long-term incentive awards will be reviewed from time to time based on personal performance, company performance and market conditions and benchmarked against market compensation packages for chief executive officers at comparable financial institutions, and will be no less than those paid to the Executive Vice Chairman of the Board.

-1-

| 2. | Termination of Employment Agreement Severance. The Corporation has determined to terminate your right to any severance pursuant to your Employment Agreement, in compliance with the Code Section 409A change in control plan termination rules. Accordingly, the cash severance that would have been payable to you in connection with a qualifying termination under Section 4(g)(ii) of your Employment Agreement (with the “Severance Payment” amount calculated based on your annual base salary as of the Closing Date and the amount of your performance bonus earned for the completed fiscal year prior to the Closing Date) will be paid in a lump sum on the one-year anniversary of the Closing Date (the “Retention Payment”), subject to your continued employment through such date. The final amount of the Retention Payment will be determined at or around the Closing Date and shall be no less than the severance that would have been available to you under Section 4(g)(ii) of your Employment Agreement. In the event you experience a Qualifying Termination (as defined below), or in the event of a termination of employment due to your death or disability (as described in your Employment Agreement), in each case, prior to the one-year anniversary of the Closing Date, your Retention Payment will be paid in full on the first regular pay date immediately following the date on which the Release Requirements (as defined below) are satisfied, and will not be subject to the clawback described below. In consideration for the covenants set forth in this letter agreement, (a) you hereby acknowledge and agree that no severance benefits or payments will be due under Section 4 of your Employment Agreement in the event of any termination of your employment following the Closing Date and (b) you agree that in the event of a termination of employment for Cause (as defined in your Employment Agreement) or resignation other than due to a Constructive Discharge (as defined in your Employment Agreement, but subject to the section entitled “Waiver of Constructive Discharge” below) (i) between the payment date of the Retention Payment and the two-year anniversary of the Closing Date, you will promptly repay two-thirds of the Retention Payment or (ii) between the two-year and three-year anniversaries of the Closing Date, you will promptly repay one-third of the Retention Payment.

| 3. | Severance. In the event that, prior to the end of the Specified Period, (a) the Succession Plan does not occur in accordance with the Merger Agreement and you resign in accordance with the notice and timing procedures for Constructive Discharge in your Employment Agreement or (b) you experience a termination of your employment without Cause (as defined in your Employment Agreement) or by reason of Constructive Discharge (as defined in your Employment Agreement, but subject to the section entitled “Waiver of Constructive Discharge” below) (each such termination of employment in clauses (a) and (b), a “Qualifying Termination”), you will be entitled to receive (i) any annual bonus or long-term incentive award earned or accrued for a prior performance period that has not yet been paid, (ii) the greater of (A) an amount equal to the sum of (x) your then applicable base salary through the remainder of the Specified Period and (y) annual performance bonuses (based on your then most recent annual performance bonus) that would have been earned or accrued during the remainder of the Specified Period and (B) an amount equal to the sum of your then applicable annual base salary and then most recent annual performance bonus, (iii) payment for the value of the contributions that would have been made to you or for your benefit under all applicable retirement and other employee benefit plans had your employment continued through December 31 of the year in which your termination of employment occurs and (iv) continuing coverage under all existing life, health and disability programs for one year following your termination date. In the event you experience a termination of employment due to your death or disability (as described in your Employment Agreement), you will be entitled to receive the amounts specified in (i), (ii)(B), (iii) and (iv). All amounts under this section will be payable in equal bi-weekly installments commencing on the first regular pay date immediately following the date on which the Release Requirements are satisfied, for the greater of the remainder of the Specified Period or 12 months. In order to satisfy the “Release Requirements”, you must: (1) execute and deliver to the Corporation a separation agreement which includes a release of all claims in such form as requested by the Corporation within 22 days following your termination date (or any such longer period if required by applicable law and communicated to you) and do not revoke the release during the seven-day period following the execution date (or any such longer period if required by applicable law and communicated to you) and (2) remain in compliance with the restrictive covenants described in the section entitled “Non-Competition” below. Amounts under this letter agreement that are conditioned on the satisfaction of the Release Requirements will be paid or will commence, if at all, in accordance with the terms of this letter agreement but in no event later than 75 days following your termination date and only if such Release Requirements have been satisfied prior to such date. In the event that the 29-day period (or any such longer period if required by applicable law and communicated to you) described in the Release Requirements begins in one calendar year and ends in a second calendar year, any payment that is conditioned on the satisfaction of the Release Requirements shall commence in the second calendar year. For purposes of Code Section 409A, each payment made under this letter agreement will be treated as a separate payment.

-2-

| 4. | Outstanding Equity Awards. Your Corporation equity awards will continue to be outstanding equity awards of the Surviving Corporation and will vest in accordance with their respective terms; provided, however, that (a) performance criteria on all performance-based restricted stock units (the “PSUs”) outstanding as of the Closing Date shall be deemed satisfied at Closing based on actual performance as of immediately prior to the Closing Date in accordance with the Merger Agreement and (b) such PSUs will only be subject to service-based vesting (the “Service Vesting PSUs”). In the event you experience a Qualifying Termination prior to the end of the Specified Period, (a) your outstanding time-based restricted stock unit awards (and any other time-based equity awards, including the Service Vesting PSUs) will accelerate and vest in full and settle at the earliest time permitted without triggering a tax or penalty under Section 409A of the Internal Revenue Code and (b) the service condition with respect to your then-outstanding equity awards that are subject to performance-based vesting conditions will be waived and such performance-based equity awards will remain outstanding and eligible to vest based on achievement of the relevant performance metrics at the end of the applicable performance period. You hereby waive any right to “single-trigger” accelerated vesting of your unvested equity awards of the Corporation solely as a result of the transactions contemplated by the Merger Agreement or any further change in control. The vesting treatment on retirement, death and disability applicable to your currently outstanding Corporation equity awards will continue to apply, including following the end of the Specified Period.

| 5. | Waiver of Constructive Discharge. You hereby acknowledge and agree that your removal as Chief Executive Officer of Busey Bank at the Closing Date and your removal as Chief Executive Officer of the Surviving Corporation as of the earlier of (a) the 12-month anniversary of the closing of the Bank Merger and (b) the 18-month anniversary of the Effective Time, and the associated changes resulting from the Succession Plan will not give rise to Constructive Discharge under Section 4(c) of your Employment Agreement. In addition, you hereby agree to waive your right to terminate your employment within one year after a Change of Control (as defined in the Employment Agreement) pursuant to Section 4(d) of your Employment Agreement.

| 6. | Non-Competition. You will continue to be bound by the restrictive covenants set forth in your Employment Agreement and you hereby acknowledge and agree that until the later of (a) one year following your termination of employment and (b) the end of the Specified Period, you will not directly or indirectly compete with the business of the Corporation and its subsidiaries and affiliates, including by doing any of the following: engage or invest in, own, manage, operate, control, finance, participate in the ownership, management, operation or control of, be employed by, associate with or in any manner be connected with, serve as an employee, officer or director of or consultant to, lend your name or any similar name to, lend your credit to, or render services or advice to any person, firm, partnership, corporation, trust or other entity that owns or operates, or is, a bank, savings and loan association, credit union, wealth management or investment advisory firm, or similar financial institution (a “Financial Institution”) with any office located, or to be located at an address identified in a filing with any regulatory authority, within the Restrictive Area (as defined below). “Restrictive Area” means an area that encompasses a 50-mile radius from each banking and other office location of the Corporation and its subsidiaries and affiliates, as they may exist from time to time. The foregoing non-competition covenant shall not prohibit you from owning directly or indirectly capital stock or similar securities that are listed on a securities exchange or quoted on a national securities exchange that do not represent more than one percent (1%) of the outstanding capital stock of any Financial Institution. The Corporation may assign any of its rights under the non-competition covenant described herein to Busey Bank at any time. In addition, Busey Bank shall be a third-party beneficiary of this Section 6 entitled to enforce any rights thereunder.

-3-

| 7. | Code Section 280G. You hereby acknowledge and agree that, from and following the Closing Date, you will not be entitled to the excise tax gross-up set forth in Section 4(g)(iv) of your Employment Agreement. Notwithstanding anything to the contrary in Section 4(g)(iv) of your Employment Agreement, you hereby agree that in the event that, after the Closing Date, any payment under this letter agreement or your Employment Agreement, either separately or in conjunction with any other payments, (a) constitutes “parachute payments” within the meaning of Section 280G of the Code, and (b) but for this provision, would be subject to the excise tax imposed by Section 4999 of the Code, then such payments and benefits will be either (i) delivered in full, or (ii) delivered as to such lesser extent that would result in no portion of such payments and benefits being subject to excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state and local income and employment taxes and the excise tax imposed by Section 4999 of the Code (and any equivalent state or local excise taxes), results in the receipt by you on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such payments and benefits may be taxable under Section 4999 of the Code. Any reduction in payments and/or benefits required by this provision will occur in the following order: (A) reduction of cash payments; (B) reduction of vesting acceleration of equity awards; and (C) reduction of other benefits paid or provided to you. In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant for equity awards. If two or more equity awards are granted on the same date, each award will be reduced on a pro-rata basis.

| 8. | Miscellaneous. Except as set forth above, the terms of your Employment Agreement will remain in full force and effect. Section headings herein are for reference purposes only and shall not affect the interpretation of the provisions hereof.

Michael J. Maddox

At the address provided to the Corporation

Dear Michael:

Reference is made to the Agreement and Plan of Merger, dated as of August 26, 2024, between First Busey Corporation (the “Corporation”) and CrossFirst Bankshares, Inc.

| 2. | Retention Award. The Corporation has determined to terminate your right to any severance pursuant to Section 3.3 of the Employment Agreement and Sections 5(a)(i) and (ii) of the Severance Plan. Accordingly, the cash severance that would have been payable to you in connection with a qualifying termination under Section 5 of the Severance Plan will be converted into a cash retention award (the “Retention Payment”). The final amount of the Retention Payment will be determined at or around the Closing Date and shall be no less than the severance that would have been available to you under Section 3.3 of your Employment Agreement and Sections 5(a)(i) and (ii) of the Severance Plan. The Retention Payment will vest and be paid in equal annual installments on each of the following three anniversaries of the Closing, subject to your continued employment through each such dates.

In the event you experience a termination of employment due to your death or Disability (as defined in the Severance Plan), you will be entitled to receive a lump sum cash payment on the 60th day following your termination date, subject to compliance with the Release Requirements in Section 3.4(c) of the Employment Agreement, equal to the sum of (1) the Accrued Obligations (as defined in the Employment Agreement) and (2) 12 times the employer portion of the monthly COBRA continuation premium to cover you and your dependents enrolled under the Corporation’s health, vision and dental plans in effect as of the termination date. You hereby acknowledge and agree that no severance benefits or payments will be due to you under Section 3 of the Employment Agreement or Section 4 of the Severance Plan in the event of any termination of your employment following the Closing Date. Amounts under this letter agreement that are conditioned on the satisfaction of the Release Requirements will be paid or will commence, if at all, in accordance with the terms of this letter agreement but in no event later than 75 days following your termination date and only if such Release Requirements have been satisfied prior to such date.

FOR IMMEDIATE RELEASE

August 27, 2024

First Busey Corporation and CrossFirst Bankshares, Inc.

Announce Transformative Partnership

Creates Compelling and Diversified Commercial Banking Franchise with $20 Billion in Assets, Extending Busey’s Market Presence to Arizona, Colorado, Kansas, New Mexico, Oklahoma and Texas

CHAMPAIGN, IL and LEAWOOD, KS—First Busey Corporation (“Busey”) (Nasdaq: BUSE), the holding company for Busey Bank, and CrossFirst Bankshares, Inc. (“CrossFirst”) (Nasdaq: CFB), the holding company for CrossFirst Bank, jointly announced today the signing of a definitive agreement and plan of merger, pursuant to which CrossFirst will merge with and into Busey (the “Merger”) in an all-common stock transaction valued at approximately $916.8 million, based on Busey’s closing stock price of $27.39 as of August 26, 2024. The combined company, which will operate under the Busey brand, will have approximately $20 billion in total assets, approximately $17 billion in total deposits and approximately $13 billion in wealth management assets under care.

“The partnership between our high-quality franchises is a great fit from a strategic, financial and cultural perspective, and we look forward to capitalizing on the many opportunities we see as a combined company in 2025 and beyond,” said Busey Chairman and CEO Van Dukeman. “CrossFirst is a natural fit alongside Busey’s established commercial and wealth management offerings and our payment technology solutions business, FirsTech, Inc. By leveraging CrossFirst’s established presence in attractive markets with compelling growth potential, this partnership is expected to serve as a catalyst for additional commercial banking growth as well as expanded opportunities to grow our existing wealth management and payments businesses. We are excited for our associates, customers and shareholders to experience our next chapter as Busey and CrossFirst combine to form a premier commercial bank that maintains the community bank values our customers and communities expect and deserve.”

Mike Maddox, CrossFirst CEO, President and Director, stated, “Founded on the ideals of extraordinary, personal service provided by outstanding, local bankers, our dedicated associates at CrossFirst have built strong, trusting relationships with our clients and the markets we serve. We believe Busey is the right partner to continue CrossFirst’s customer- and community-focus. Because of our like-minded cultures, our complementary business models and manner in which we operate, we are confident this partnership will create significant benefits for our teams, customers, communities and shareholders.”

Strategic Benefits of the Partnership

The partnership will extend Busey’s regional operating model in the high-growth metro markets of Kansas City, Wichita, Dallas/Fort Worth, Denver and Phoenix while bolstering its commercial banking relationships and offering additional opportunities to grow its wealth management business and FirsTech, Inc., Busey’s payment technology solutions subsidiary. The combined company will further strengthen its deep commitment to and extensive skill set in commercial banking.

The combination is expected to create a premier full-service commercial bank serving clients from 77 full-service locations across 10 states with combined total assets of approximately $20 billion, $17 billion in total deposits, $15 billion in total loans and $13 billion in wealth assets under care. With a diversified client, loan and deposit base, this scale provides opportunities to augment business models through new customer and product channels.

Through compatible banking philosophies and cultures, complementary business models, combined capital strength and increased economies of scale, the combination is expected to significantly enhance key performance metrics with meaningful improvements in net interest margin and efficiency, driving increased profitability and returns to our shareholders. Pro forma calculations estimate Busey earnings per share accretion of approximately 20% in 2026, the first full year of combined operations, excluding one-time merger-related charges and assuming fully phased-in cost savings. Tangible book value per share dilution is projected to be modest at -0.6% with a forecasted earnback period of approximately six months. Capital ratios are expected to be significantly above “well-capitalized” thresholds with 9.6% leverage, 11.0% CET1 and 14.1% total risk-based capital. The transaction is expected to result in an internal rate of return of over 19%. With a combined loan-to-deposit ratio of 86%, C&D concentration of 60% and CRE concentration of 250%, the pro forma company will be well-positioned for future growth.

Both Busey and CrossFirst have extensive experience in successfully integrating with merger partners and are acutely focused on ensuring a smooth transition. Between the two management teams, Busey and CrossFirst have successfully navigated 11 mergers and integrations since 2013.

Transaction Details

The merger has been unanimously approved by each company’s board of directors.

In the merger, CrossFirst shareholders will receive 0.6675 shares of Busey common stock for each share held of CrossFirst common stock. CrossFirst’s common shareholders, which currently do not receive a dividend, will be eligible to receive Busey’s ongoing dividends as declared following the closing of the merger.

Upon completion of the transaction, Busey’s shareholders will own approximately 63.5% of the combined company and CrossFirst’s shareholders will own approximately 36.5% of the combined company, on a fully-diluted basis, which will continue to trade on the Nasdaq under the “BUSE” stock ticker symbol.

Completion of the merger is subject to customary closing conditions, including the approval of both Busey and CrossFirst shareholders and the regulatory approvals for the holding company merger and the bank merger. With approvals, the parties expect to close the holding company merger in the first or second quarter of 2025.

Name and Headquarters

The combined holding company will continue to operate under the First Busey Corporation name and the combined bank will operate under the Busey Bank name. It is anticipated that CrossFirst Bank will merge with and into Busey Bank in mid-2025. At the time of the bank merger, CrossFirst Bank locations will become service centers of Busey Bank.

Busey Bank’s headquarters will remain in Champaign, Illinois—near where Busey was founded more than 155 years ago. The majority of Busey’s stable deposit base and wealth management assets under care are within its legacy footprint.

The headquarters of the holding company will move to Leawood, Kansas—at the site of the current CrossFirst headquarters in the Kansas City area, which will be central to the combined company’s new footprint, providing benefits for ease of travel, accessibility and visibility.

Governance, Leadership and Culture

The Board of Directors of the combined company will be comprised of thirteen (13) members, eight (8) from Busey or Busey Bank and five (5) from CrossFirst, with Van Dukeman serving as Executive Chairman and CEO, Mike Maddox as President and Executive Vice Chairman, and Rod Brenneman— current independent Chairman of the Board of CrossFirst—as Lead Independent Director.

Management of the combined company will be a combination of both Busey and CrossFirst executives. Van Dukeman will continue to serve as Executive Chairman and CEO of Busey and Executive Chairman of Busey Bank. Mike Maddox will become President and Executive Vice Chairman of Busey and CEO of Busey Bank. Mr. Maddox will succeed Mr. Dukeman as CEO of Busey on the earlier of the one-year anniversary of the bank merger or the 18-month anniversary of the holding company merger, with Dukeman remaining the Executive Chairman of both Busey and Busey Bank.

The remainder of the management team of the combined company will be led by a well-respected group of individuals with significant financial services and M&A integration experience. This group will provide continuity of leadership both during and beyond integration. Current Busey executives—Chief Financial Officer Jeff Jones, Chief Operating Officer Amy Randolph, Chief Risk Officer Monica Bowe and General Counsel John Powers—will remain in their current roles with the combined company. Randy Rapp, current President of CrossFirst Bank, will assume the role of President of Busey Bank while Chip Jorstad, Busey’s current President of Credit and Bank Administration, and Amy Fauss, CrossFirst’s current Chief Operating Officer, will assume the roles of Chief Credit Officer and Chief Information and Technology Officer, respectively.

Both companies support and value an engaged and empowered workforce and are committed to building an extraordinary, service-oriented banking experience. Busey has been named among American Banker’s Best Banks to Work For since 2016; listed among 2023 and 2024’s America’s Best Banks by Forbes; and recognized in all states where it operates as a Best Place to Work, in addition to earning various wellness, training and development, philanthropic and other workplace awards. Similarly, CrossFirst continues to be honored with prestigious workplace awards including being recognized as a back-to-back winner of the Don Clifton Strengths-Based Culture award from Gallup® in 2023 and 2024 and a Best Place to Work by the Kansas City Business Journal for the past two years.

Forward‐looking statements are typically identified by such words as “believe,” “expect,” “anticipate,” “plan,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “should,” “may,” “will,” “position,” and other similar words and expressions, and are subject to numerous assumptions, risks, and uncertainties, which change over time. These forward-looking statements include, without limitation, those relating to the terms, timing and closing of the proposed transaction. Additionally, forward‐looking statements speak only as of the date they are made; Busey and CrossFirst do not assume any duty, and do not undertake, to update such forward‐looking statements, whether written or oral, that may be made from time to time, whether as a result of new information, future events, or otherwise. Furthermore, because forward‐looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those indicated in such forward-looking statements as a result of a variety of factors, many of which are beyond the control of Busey and CrossFirst. Such statements are based upon the current beliefs and expectations of the management of Busey and CrossFirst and are subject to significant risks and uncertainties outside of the control of the parties. Caution should be exercised against placing undue reliance on forward-looking statements. The factors that could cause actual results to differ materially include the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement; the outcome of any legal proceedings that may be instituted against Busey or CrossFirst; the possibility that the proposed transaction will not close when expected or at all because required regulatory, stockholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all, or are obtained subject to conditions that are not anticipated (and the risk that required regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction); the ability of Busey and CrossFirst to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of either or both parties to the proposed transaction; the possibility that the anticipated benefits of the proposed transaction will not be realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where Busey and CrossFirst do business; certain restrictions during the pendency of the proposed transaction that may impact the parties’ ability to pursue certain business opportunities or strategic transactions; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; the possibility that the parties may be unable to achieve expected synergies and operating efficiencies in the merger within the expected timeframes or at all and to successfully integrate CrossFirst’s operations and those of Busey; such integration may be more difficult, time consuming or costly than expected; revenues following the proposed transaction may be lower than expected; Busey’s and CrossFirst’s success in executing their respective business plans and strategies and managing the risks involved in the foregoing; the dilution caused by Busey’s issuance of additional shares of its capital stock in connection with the proposed transaction; effects of the announcement, pendency or completion of the proposed transaction on the ability of Busey and CrossFirst to retain customers and retain and hire key personnel and maintain relationships with their suppliers, and on their operating results and businesses generally;

the concentration of large deposits from certain clients who have balances above current FDIC insurance limits and may withdraw deposits to diversify their exposure; the level of non-performing assets on Busey’s or CrossFirst’s balance sheets;
