ARTICLE I

THE MERGER

1.1 The Merger and Bank Merger.

(a)Subject to the terms and conditions of this Agreement, in accordance with the Wisconsin Business Corporation Law (as amended from time to time, the “WBCL”) and the Iowa Business Corporation Act (the “IBCA”), at the Effective Time, MOFG shall merge with and into NIC pursuant to this Agreement. NIC shall be the Surviving Entity in the Merger and shall continue its corporate existence under the laws of the State of Wisconsin. Upon consummation of the Merger, the separate corporate existence of MOFG shall terminate.

(b)At the Bank Merger Effective Time, MOFG Bank will merge with and into Nicolet Bank. Nicolet Bank shall be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of MOFG Bank shall cease. The Bank Merger shall be implemented pursuant to an agreement and plan of merger between MOFG Bank and Nicolet Bank substantially in the form attached as Exhibit C (the “Bank Merger Agreement”), which shall be entered into by MOFG Bank and Nicolet Bank concurrently with this Agreement. Each of MOFG and NIC shall approve the Bank Merger Agreement and the Bank Merger as the sole shareholder of MOFG Bank and Nicolet Bank, respectively, and MOFG and NIC shall, and shall respectively cause MOFG Bank and Nicolet Bank to, execute certificates or articles of merger and such other agreements, documents and certificates as are necessary to make the Bank Merger effective (“Bank Merger Certificates”) at the Bank Merger Effective Time. The Bank Merger shall become effective immediately following the Effective Time or at such later time and date as specified in the Bank Merger Agreement in accordance with applicable law (the “Bank Merger Effective Time”).

(c)It is intended that the Bank Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code (together with the intended tax treatment for the Merger set

forth in Section 1.10, the “Intended Tax Treatment”), and that the Bank Merger Agreement is intended to be and will be adopted as a plan of reorganization for the purposes of Sections 354 and 361 of the Code.

1.2 Closing. Pursuant to the terms and subject to the conditions of this Agreement, the closing of the Merger (the “Closing”) will take place by electronic exchange of documents at 10:00 a.m., Central time, on a date which shall be no later than three Business Days after the satisfaction or waiver (subject to applicable law) of all 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); provided that, upon the election of NIC, the parties shall cause the Closing to occur no later than the first calendar day of the calendar month following the calendar month in which the satisfaction or waiver (subject to applicable law) of all of the conditions set forth in Article VII hereof first occurs (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by MOFG and NIC. The date on which the Closing occurs is referred to as the “Closing Date.”

1.3 Effective Time. On or (if agreed by MOFG and NIC) prior to the Closing Date, NIC and MOFG, respectively, shall cause to be filed articles of merger with the Secretary of State of the State of Iowa (the “Iowa Secretary”) in accordance with the IBCA and articles of merger with the Wisconsin Department of Financial Institutions (the “WDFI”) in accordance with the WBCL (collectively, the “Certificates of Merger”). The Merger shall become effective at such time as specified in the Certificates of Merger in accordance with the relevant provisions of the IBCA and WBCL, or at such other time as shall be provided by applicable law (such time hereinafter referred to as the “Effective Time”).

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 WBCL, the IBCA, and this Agreement.

1.5 Conversion of MOFG Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of NIC, MOFG or the holders of any securities of NIC or MOFG:

(a)Subject to Section 2.2(e), each share of the common stock, par value $1.00 per share, of MOFG (the “MOFG Common Stock”) issued and outstanding immediately prior to the Effective Time, except for shares of MOFG Common Stock owned by MOFG or NIC (in each case, other than shares of MOFG 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 MOFG or NIC in respect of debts previously contracted), shall be converted into the right to receive 0.3175 shares (the “Exchange Ratio”; and such shares, the “Merger Consideration”) of the common stock, par value $0.01 per share, of NIC (the “NIC Common Stock”); it being understood that at and after the Effective Time, pursuant to Section 1.6, the NIC Common Stock, including the shares issued to former holders of MOFG Common Stock, shall be the common stock of the Surviving Entity.

(b)All of the shares of MOFG 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 Certificate”; it being understood that any reference herein to

“Old Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of MOFG Common Stock) previously representing any such shares of MOFG Common Stock shall thereafter represent only the right to receive (i) a New Certificate (as defined below) representing the number of whole shares of NIC Common Stock that such shares of MOFG Common Stock have been converted into the right to receive, (ii) cash in lieu of fractional shares which the shares of MOFG Common Stock represented by such Old Certificate 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 that the holder thereof has the right to receive pursuant to Section 2.2, in each case, without any interest thereon. If, prior to the Effective Time, the outstanding shares of NIC Common Stock or MOFG 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 structural 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 NIC and the holders of MOFG 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 MOFG or NIC 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 MOFG Common Stock that are owned by MOFG or NIC (in each case, other than shares of MOFG 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 MOFG or NIC in respect of debts previously contracted) shall be cancelled and shall cease to exist and no NIC Common Stock or other consideration shall be delivered in exchange therefor.

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

1.7 Treatment of MOFG Equity Awards.

(a)At the Effective Time, each then-outstanding award of restricted stock units with respect to shares of MOFG Common Stock (a “MOFG RSU Award”) shall, automatically and without any required action on the part of the holder thereof, be fully vested, canceled and converted into the right to receive a number of shares of NIC Common Stock equal to the product (rounded to the nearest whole number) of (i) the number of shares of MOFG Common Stock subject to such MOFG RSU Award immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio.

(b)At the Effective Time, each then-outstanding performance restricted stock unit award with respect to shares of MOFG Common Stock (a “MOFG PSU Award”) shall, automatically and without any required action on the part of the holder thereof, be fully vested, canceled and converted into the right to receive (i) a number of shares of NIC Common Stock equal to the product (rounded to the nearest whole number) of (x) the

number of shares of MOFG Common Stock subject to such MOFG PSU Award immediately prior to the Effective Time based on the higher of target performance and actual performance through the Effective Time as reasonably determined by the compensation committee of the Board of Directors of MOFG (the “MOFG Compensation Committee”) multiplied by (y) the Exchange Ratio, plus (ii) a cash payment in respect of any accrued but unpaid dividend equivalents on such MOFG PSU Award.

(c)At or prior to the Effective Time, MOFG, the Board of Directors of MOFG and the MOFG Compensation Committee, as applicable, shall adopt any resolutions and take any actions that are necessary or appropriate to effectuate the provisions of this Section 1.7.

(d)NIC shall take all corporate actions that are necessary for the treatment of the MOFG RSU Awards and MOFG PSU Awards (together, the “MOFG Equity Awards”) pursuant to Sections 1.7(a) and 1.7(b), including the reservation, issuance and listing of NIC Common Stock as necessary to effect the transactions contemplated by this Section 1.7. NIC shall issue the consideration contemplated by this Section 1.7, less any applicable Taxes required to be withheld in respect of such consideration under applicable Tax law, as promptly as practicable following the Effective Time (but in no event later than two (2) Business Days after the Closing Date).

1.8 Articles of Incorporation of Surviving Entity. At the Effective Time, the articles of incorporation of NIC, as in effect immediately prior to the Effective Time, shall be the articles of incorporation of the Surviving Entity until thereafter amended in accordance with the terms thereof and applicable law.

1.9 Bylaws of Surviving Entity. At the Effective Time, the bylaws of NIC, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Entity until thereafter amended in accordance with the terms thereof and applicable law.

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

ARTICLE II

EXCHANGE OF SHARES

2.1 NIC to Make Consideration Available. At or prior to the Effective Time, NIC shall deposit, or shall cause to be deposited, with an exchange agent selected by NIC and reasonably satisfactory to MOFG (the “Exchange Agent”), for exchange in accordance with this Article II for the benefit of the holders of Old Certificates, certificates or, at NIC’s option, evidence in book-entry form, representing shares of NIC Common Stock to be issued pursuant to Section 1.5 (collectively, referred to herein as “New Certificates”), and cash in lieu of any fractional shares to be paid pursuant to Section 2.2(e) (such cash and New Certificates, together with any dividends or distributions with respect to shares of NIC Common Stock payable in accordance with Section 2.2(b), being referred to as the “Exchange Fund”).

2.2 Exchange of Shares.

(a)As promptly as practicable after the Effective Time, but in no event later than five Business Days thereafter, the Surviving Entity shall cause the Exchange Agent to mail to each holder of record of one or more Old Certificates, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates representing the number of whole shares of NIC Common Stock and any cash in lieu of fractional shares, which the shares of MOFG Common Stock represented by such Old Certificate or Old Certificates 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) (such materials and instructions to include customary provisions with respect to delivery of an “agent’s message” with respect to any book-entry shares). Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent (it being understood that no certificates shall be required to be delivered for shares of MOFG Common Stock held in book-entry form at the Effective Time), together with such properly completed and duly executed letter of transmittal, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, as applicable, (i) a New Certificate representing that number of whole shares of NIC Common Stock to which such holder of MOFG Common Stock shall have become entitled pursuant to the provisions of Article I, and (ii) a check representing the amount of (x) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II, and (y) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Certificate or Old Certificates 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 Certificates. Until surrendered as contemplated by this Section 2.2, each Old Certificate 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 NIC Common Stock which the shares of MOFG Common Stock represented by such Old Certificate 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.

(b)No dividends or other distributions declared with respect to NIC Common Stock shall be paid to the holder of any unsurrendered Old Certificate until the holder thereof shall surrender such Old Certificate in accordance with this Article II. After the surrender of an Old Certificate 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 NIC Common Stock that the shares of MOFG Common Stock represented by such Old Certificate have been converted into the right to receive (after giving effect to Section 6.10).

(c)If any New Certificate representing shares of NIC Common Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates 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 Certificate representing shares of NIC Common Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates 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 MOFG of the shares of MOFG Common Stock. If, after the Effective Time, Old Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for New Certificates representing shares of NIC Common Stock, cash in lieu of fractional shares and dividends or distributions as contemplated by this Section 2.2, as applicable.

(e)Notwithstanding anything to the contrary contained in this Agreement, no New Certificates or scrip representing fractional shares of NIC Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to NIC 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 shareholder of NIC. In lieu of the issuance of any such fractional share, the Surviving Entity shall pay to each former holder of MOFG 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 NIC Common Stock on the New York Stock Exchange (the “NYSE”) as reported by The Wall Street Journal for the consecutive period of five full trading days ending on the trading day immediately preceding the Closing Date (or, if not reported therein, in another authoritative source mutually agreed upon by MOFG and NIC) by (ii) the fraction of a share (after taking into account all shares of MOFG Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest one-thousandth when expressed in decimal form) of NIC 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.

(f)Any portion of the Exchange Fund that remains unclaimed by the former holders of MOFG Common Stock for 12 months after the Effective Time shall be paid to the Surviving Entity. Any former holders of MOFG Common Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Entity for payment of the shares of NIC Common Stock, cash in lieu of any fractional shares and any unpaid dividends and distributions on the NIC Common Stock deliverable in respect of each former share of MOFG Common Stock such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of NIC, MOFG, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of shares of MOFG Common Stock for

any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by former holders of shares of MOFG Common Stock immediately prior to the time at which such amounts would otherwise permanently escheat to, or become property of, any Governmental Entity shall, to the extent permitted by applicable law, become the property of the Surviving Entity, free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.

(g)The Surviving Entity 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 NIC Common Stock, cash dividends or distributions payable pursuant to this Section 2.2 or any other amounts otherwise payable pursuant to this Agreement or otherwise to any holder of MOFG Common Stock or MOFG Equity Awards, such amounts as it is required to deduct and withhold with respect to the making of such payment or distribution under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so deducted or withheld by the Surviving Entity or the Exchange Agent, as the case may be, and paid over to the appropriate Governmental Entity, the deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of MOFG Common Stock or MOFG Equity Awards in respect of which the deduction and withholding was made by the Surviving Entity or the Exchange Agent, as the case may be.

(h)In the event any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if required by the Surviving Entity or the Exchange Agent, the posting by such person of a bond in such amount as the Surviving Entity or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the shares of NIC Common Stock and any cash in lieu of fractional shares, and dividends or distributions, deliverable in respect thereof pursuant to this Agreement.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF MOFG

Except (a) as disclosed in the disclosure schedule delivered by MOFG to NIC concurrently herewith (the “MOFG Disclosure Schedule”) (it being understood that (i) no 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 MOFG Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by MOFG that such item represents a material exception or fact, event or circumstance or that such item would reasonably be expected to have a Material Adverse Effect, and (iii) any disclosures made with respect to a section of this Article III shall be deemed to qualify (1) any other section of this Article III specifically referenced or cross-referenced, and (2) any 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) except with respect to Sections 3.1, 3.2, 3.3 and 3.4, as disclosed in any MOFG Reports publicly filed with or

furnished to the SEC by MOFG since December 31, 2022, 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 cautionary, predictive or forward-looking in nature), MOFG hereby represents and warrants to NIC as follows:

3.1 Corporate Organization.

(a)MOFG is a corporation duly organized, validly existing and in good standing under the laws of the State of Iowa, is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”), and has elected to be treated as a financial holding company under the BHC Act. MOFG has the corporate power and authority to own, lease or operate all of its properties and assets and to carry on its business as it is now being conducted in all material respects. MOFG is duly licensed or qualified to do business and in good standing (to the extent such concept (or a similar concept) exists in such jurisdiction) in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, leased or operated 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 MOFG. As used in this Agreement, the term “Material Adverse Effect” means, with respect to NIC, MOFG or the Surviving Entity, 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, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements (and, in either case, any authoritative interpretations thereof), (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, (D) changes, after the date hereof, resulting from hurricanes, earthquakes, tornados, naturally-occurring floods or other natural disasters or from any outbreak of any disease, pandemic, epidemic 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) or (F) a decline in the trading price of a party’s common stock in and of itself or the failure, in and of itself, to meet earnings projections or internal or published industry

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); 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, the term “Subsidiary” when used with respect to any person, means any subsidiary of such person as defined in Rule 1-02(x) of Regulation S-X promulgated by the SEC or the BHC Act. True and complete copies of the amended and restated articles of incorporation of MOFG, as amended (the “MOFG Articles”), and the third amended and restated bylaws of MOFG (the “MOFG Bylaws”), in each case, as in effect as of the date of this Agreement, have previously been made available by MOFG to NIC.

(b)Except as would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on MOFG, each Subsidiary of MOFG (a “MOFG Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly licensed or 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, leasing or operation of property or the conduct of its business requires it to be so licensed or qualified or in good standing, and (iii) has all requisite corporate power and authority to own, lease or operate its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of MOFG or any Subsidiary of MOFG to pay dividends or distributions except, in the case of MOFG or a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all similarly regulated entities. MOFG Bank is the only depository institution Subsidiary of MOFG, and the deposit accounts of MOFG Bank are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund (as defined in Section 3(y) of the Federal Deposit Insurance Act of 1950 (the “FDI Act”)) 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, to the knowledge of MOFG, threatened. Section 3.1(b) of the MOFG Disclosure Schedule sets forth a true, correct and complete list of all Subsidiaries of MOFG as of the date hereof. No Subsidiary of MOFG is in violation of any of the provisions of its articles or certificate of incorporation or bylaws (or comparable organizational documents). True and complete copies of the organizational documents of MOFG Bank as in effect as of the date of this Agreement have previously been made available by MOFG to NIC. There is no person whose results of operations, cash flows, changes in shareholders’ equity or financial position are consolidated in the financial statements of MOFG other than the MOFG Subsidiaries.

Other than MOFG Equity Awards, no equity or equity-based awards (including any cash awards where the amount of payment is determined, in whole or in part, based on the price of any capital stock of MOFG or any of its Subsidiaries) are outstanding. No MOFG Subsidiary owns any capital stock of MOFG. There are no voting trusts, shareholder agreements, proxies or other agreements in effect to which MOFG or any of its Subsidiaries is a party with respect to the voting or transfer of MOFG Common Stock, capital stock or other voting or equity securities or ownership interests of MOFG or granting any shareholder or other person any registration rights.

(b)Except as would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on MOFG, MOFG owns, directly or indirectly, all the issued and outstanding shares of capital stock or other equity ownership interests of each of the MOFG Subsidiaries, free and clear of any liens, claims, title defects, mortgages, pledges, charges, and security interests whatsoever, and any other encumbrances securing a payment or the performance of an obligation (collectively, “Liens”), and all of such shares or equity ownership interests are duly authorized and validly issued and are fully paid, nonassessable (except, with respect to Subsidiaries that are depository institutions, as provided under any provision of applicable state law comparable to 12 U.S.C. § 55) and free of preemptive rights, with no personal liability attaching to the ownership thereof.

3.3 Authority; No Violation.

(a)MOFG has full corporate power and authority to execute and deliver this Agreement and, subject to the shareholder and other actions described below, to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby (including the Merger and the Bank Merger) have been duly and validly approved by the Board of Directors of MOFG. The Board of Directors of MOFG has determined, by the unanimous vote of directors present at the applicable meeting, that the transactions contemplated hereby (including the Merger and the Bank Merger), on the terms and conditions set forth in this Agreement, are advisable and in the best interests of MOFG and its shareholders, has approved this Agreement and the transactions contemplated hereby (including the Merger and the Bank Merger), and has directed that this Agreement be submitted to MOFG’s shareholders for approval at a meeting of such shareholders and has adopted a resolution to the foregoing effect. Except for the approval of this Agreement by the affirmative vote of the holders of a majority of the outstanding MOFG Common Stock entitled to vote on such matter (the “Requisite MOFG Vote”), and the approval of the Bank Merger Agreement by MOFG as MOFG Bank’s sole shareholder, no other corporate proceedings on the part of MOFG are necessary to approve this Agreement or to consummate the transactions contemplated hereby (other than the submission to the shareholders of MOFG of an advisory (non-binding) vote on the compensation that may be paid or become payable to MOFG’s named executive officers that is based on or otherwise related to the transactions contemplated by this Agreement). This Agreement has been duly and validly executed and delivered by MOFG and (assuming due authorization, execution and delivery by NIC) constitutes a valid and binding obligation of MOFG, enforceable against MOFG in accordance with its terms (except in all cases as such enforceability may be limited by bankruptcy, insolvency, moratorium, reorganization or

similar laws of general applicability affecting the rights of creditors generally and the availability of equitable remedies (the “Enforceability Exceptions”)).

(b)Neither the execution and delivery of this Agreement by MOFG nor the consummation by MOFG of the transactions contemplated hereby (including the Merger and the Bank Merger), nor compliance by MOFG with any of the terms or provisions hereof, will (i) violate any provision of the MOFG Articles, the MOFG Bylaws or the organizational documents of any MOFG Subsidiary, or (ii) assuming that the consents and approvals referred to in Section 3.4 are duly obtained, (x) violate any law, statute, code, ordinance, rule, regulation, judgment, order, writ, decree or injunction applicable to MOFG or any of its Subsidiaries or any of their respective properties or assets, or (y) violate, conflict with, result in a breach of any provision of or the loss of any benefit under, constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, result in the termination of or a right of termination or cancellation under, accelerate the performance required by, or result in the creation of any Lien upon any of the respective properties or assets of MOFG or any of its Subsidiaries under, any of the terms, conditions or provisions of any note, bond, mortgage, indenture, deed of trust, license, lease, agreement or other instrument or obligation to which MOFG or any of its Subsidiaries is a party, or by which they or any of their respective properties or assets may be bound, except (in the case of clauses (x) and (y) above) for such violations, conflicts, breaches, defaults, terminations, cancellations, accelerations or creations that, either individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on MOFG.

MOFG and each of its Subsidiaries have timely filed (or furnished) all reports, forms, correspondence, registrations and statements, together with any amendments required to be made with respect thereto, that they were required to file (or furnish, as applicable) since December 31, 2022 with (a) any state regulatory authority, (b) the SEC, (c) the Federal Reserve Board, (d) the FDIC, (e) any foreign regulatory authority, and (f) any self-regulatory organization (an “SRO”) (clauses (a) - (f), collectively “MOFG Regulatory Agencies”, and together with the NIC Regulatory Agencies, the “Regulatory Agencies”), including any report, form, correspondence, registration or statement required to be filed (or furnished, as applicable) pursuant to the laws, rules or regulations of the United States, any state, any foreign entity or any MOFG Regulatory Agency, and have paid all fees and assessments due and payable in connection therewith, except where the failure to file (or furnish, as applicable) such report, form, correspondence, registration or statement or to pay such fees and assessments, either individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on MOFG. As of their respective dates, such reports, forms, correspondence, registrations and statements, and other filings, documents and instruments were complete and accurate and complied with all applicable laws and regulations, in each case, except as would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on MOFG. Subject to Section 9.14, except for normal examinations conducted by a MOFG Regulatory Agency in the ordinary course of business of MOFG and its Subsidiaries, no MOFG Regulatory Agency or governmental agency or authority has initiated or has pending any proceeding or, to the knowledge of MOFG, investigation into the business or operations of MOFG or any of its Subsidiaries since December 31, 2022, except where such proceedings or investigations would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on MOFG.

3.6 Financial Statements.

(a)The financial statements of MOFG and its Subsidiaries included (or incorporated by reference) in the MOFG Reports (including the related notes, where applicable) (i) have been prepared from, and are in accordance with, the books and records of MOFG and its Subsidiaries in all material respects, (ii) fairly present in all material respects the consolidated balance sheets, results of operations, consolidated statements of cash flows, consolidated statements of comprehensive income, changes in shareholders’ equity and

consolidated financial position of MOFG and its Subsidiaries for the respective fiscal periods or as of the respective dates therein set forth (subject in the case of unaudited statements to year-end audit adjustments normal in nature and amount), (iii) complied, as of their respective dates of filing with the SEC, in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto, and (iv) have been prepared in accordance with GAAP consistently applied during the periods involved, except, in each case, as indicated in such statements or in the notes thereto. Since December 31, 2022, no independent public accounting firm of MOFG has resigned (or informed MOFG that it intends to resign) or been dismissed as independent public accountants of MOFG as a result of or in connection with any disagreements with MOFG on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

(b)Except as would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on MOFG, neither MOFG nor any of its Subsidiaries has any liability of any nature whatsoever (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 MOFG included in its Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2025 (including any notes thereto) and for liabilities incurred in the ordinary course of business consistent with past practice since June 30, 2025, or in connection with this Agreement and the transactions contemplated hereby.

(c)The records, systems, controls, data and information of MOFG and its Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership of, or leased or provided as a service to, MOFG or its Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership that would not reasonably be expected to have a Material Adverse Effect on MOFG. MOFG (x) has implemented and maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) to ensure that material information relating to MOFG, including its Subsidiaries, is made known to the chief executive officer and the chief financial officer of MOFG by others within those entities as appropriate to allow timely decisions regarding required disclosures and to make the certifications required by the Exchange Act and Sections 302 and 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 (the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”), and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to MOFG’s outside auditors and the audit committee of MOFG’s Board of Directors (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to adversely affect MOFG’s ability to record, process, summarize and report financial information, and (ii) to the knowledge of MOFG, any fraud, whether or not material, that involves management or other employees who have a significant role in MOFG’s internal controls over financial reporting. To the knowledge of MOFG, any such disclosures were made in writing by management to MOFG’s auditors and audit committee and true, correct and complete copies of such disclosures have been made available by MOFG to NIC. As of the date hereof, neither

MOFG nor its independent audit firm has identified, and, to the knowledge of MOFG, no circumstances exist upon which MOFG or its independent audit firm would reasonably be expected to identify after the date hereof, any un-remediated material weakness in internal controls over financial reporting or disclosure controls and procedures. To the knowledge of MOFG, there is no reason to believe that MOFG’s outside auditors and its chief executive officer and chief financial officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, without qualification, when next due.

(d)Since December 31, 2022, (i) neither MOFG nor any of its Subsidiaries, nor, to the knowledge of MOFG, any director, officer, auditor, accountant or representative of MOFG or any of its Subsidiaries, has received or otherwise had or obtained knowledge of any material complaint, allegation, assertion or claim, whether written or oral, regarding the accounting or auditing practices, procedures, methodologies or methods (including with respect to loan loss reserves, write-downs, charge-offs and accruals) of MOFG or any of its Subsidiaries or their respective internal accounting controls, including any material complaint, allegation, assertion or claim that MOFG or any of its Subsidiaries has engaged in questionable accounting or auditing practices, and (ii) no employee of or attorney representing MOFG or any of its Subsidiaries, whether or not employed by MOFG or any of its Subsidiaries, has reported evidence of a material violation of securities laws or banking laws, breach of fiduciary duty or similar violation by MOFG or any of its Subsidiaries or any of their respective officers, directors, employees or agents to the Board of Directors of MOFG or any committee thereof or the Board of Directors or similar governing body of any MOFG Subsidiary or any committee thereof, or to the knowledge of MOFG, to any director or officer of MOFG or any MOFG Subsidiary.

3.7 Broker’s Fees. With the exception of the engagement of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., neither MOFG nor any MOFG Subsidiary nor any of their respective officers or directors has employed any broker, finder or financial advisor or incurred any liability for any broker’s fees, commissions or finder’s fees in connection with the Merger, the Bank Merger or related transactions contemplated by this Agreement. MOFG has disclosed to NIC as of the date hereof the aggregate fees provided for in connection with the engagement by MOFG of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. related to the Mergers and the other transactions contemplated hereunder.

3.8 Absence of Certain Changes or Events.

(a)Since December 31, 2024, there has not been any effect, change, event, circumstance, condition, occurrence or development that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on MOFG.

(j)Except as set forth on Section 3.11(j) of the MOFG Disclosure Schedule, neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (either alone or in conjunction with any other event) result in the acceleration of vesting, exercisability, funding or delivery of, or increase in the amount or value of, any payment, right or other benefit to any employee, officer,

individual service provider, or director of MOFG or any of its Subsidiaries, or result in any limitation on the right of MOFG or any of its Subsidiaries to amend, merge, terminate or receive a reversion of assets from any MOFG Benefit Plan or related trust on or after the Effective Time. Without limiting the generality of the foregoing and except as set forth on Section 3.11(j) of the MOFG Disclosure Schedule, no amount paid or payable (whether in cash, in property, or in the form of benefits) to any employee, officer, individual service provider, or director of MOFG or any of its Subsidiaries in connection with the transactions contemplated hereby (either solely as a result thereof or as a result of such transactions in conjunction with any other event), whether under any MOFG Benefit Plan or otherwise, will be an “excess parachute payment” within the meaning of Section 280G of the Code.

There are no restrictions on the ability of NIC or any Subsidiary of NIC to pay dividends or distributions except, in the case of NIC or a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all similarly regulated entities.

ARTICLE VI

ADDITIONAL AGREEMENTS

6.1 Regulatory Matters.

(a)Promptly after the date of this Agreement, NIC and MOFG shall prepare and file with the SEC the Joint Proxy Statement, and NIC shall prepare and file with the SEC the S-4, in which the Joint Proxy Statement will be included as a prospectus, and the parties shall use reasonable best efforts to make such filings no later than 45 days after the date of this Agreement. Each of NIC and MOFG shall use its reasonable best efforts to have the S-4

declared effective under the Securities Act as promptly as practicable after such filings, and NIC and MOFG shall thereafter mail or deliver the Joint Proxy Statement to their respective shareholders. NIC and MOFG shall use their reasonable best efforts to keep the S-4 effective for so long as necessary to consummate the transactions contemplated by this Agreement. NIC shall also use its reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions contemplated by this Agreement, and MOFG shall furnish all information concerning MOFG and the holders of MOFG Common Stock as may be reasonably requested in connection with any such action.

(b)The parties hereto shall cooperate with each other and use their reasonable best efforts to (i) promptly prepare and file all necessary documentation, to effect all applications, notices, petitions and filings (and in the case of the applications, notices, petitions and filings in respect of the Requisite Regulatory Approvals, use their reasonable best efforts to make such filings within 45 days of the date of this Agreement) and (ii) obtain as promptly as practicable all permits, consents, waivers, approvals and authorizations of all third parties and Governmental Entities which are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger and the Bank Merger), and to comply with the terms and conditions of all such permits, consents, waivers, approvals and authorizations of all such Regulatory Agencies and Governmental Entities. MOFG and NIC shall each use, and shall each cause their applicable Subsidiaries to use, reasonable best efforts to obtain each such Requisite Regulatory Approval as promptly as practicable. NIC and MOFG 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 non-confidential information relating to MOFG or NIC (excluding any confidential financial information relating to individuals), 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 obtaining all permits, consents, waivers, 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 in this Agreement, and each party shall consult with the other in advance of any material meeting or conference with any Governmental Entity in connection with the transactions contemplated by this Agreement, to the extent permitted by such Governmental Entity and subject to applicable law and Section 9.14. As used in this Agreement, the term “Requisite Regulatory Approvals” shall mean all regulatory authorizations, consents, waivers, orders, non-objections and approvals (and the expiration or termination of all statutory waiting periods in respect thereof) (i) from the OCC and the Federal Reserve Board (in respect of the Merger or the Bank Merger) or (ii) referred to in Section 3.4 or Section 4.4 that are necessary to consummate the transactions contemplated by this Agreement (including the Merger and the Bank Merger), except, in the case of this clause (ii), for any such authorizations, consents, waivers, orders or

approvals the failure of which to be obtained would not be material to the Surviving Entity.

(c)In furtherance and not in limitation of the foregoing, each party shall use its reasonable best efforts to avoid the entry of, or to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that would restrain, prevent or delay the Closing. Notwithstanding the foregoing, nothing contained in this Agreement shall be deemed to require NIC or MOFG or any of their respective Subsidiaries, and neither MOFG nor any of its Subsidiaries shall be permitted (without the prior written consent of NIC), 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, waivers, approvals and authorizations of Governmental Entities that would reasonably be expected to have a material adverse effect on the Surviving Entity and its Subsidiaries, taken as a whole, after giving effect to the Merger (provided that for purposes of determining whether any of the foregoing gives rise to such a “material adverse effect”, “material adverse effect” shall be measured on a scale relative only to the size of MOFG and its Subsidiaries, taken as a whole, without NIC and its Subsidiaries) (a “Materially Burdensome Regulatory Condition”).

(d)NIC and MOFG shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and shareholders 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 NIC, MOFG 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.

(e)NIC and MOFG shall promptly advise each other upon receiving any communication from any Governmental Entity whose permit, consent, waiver, approval or authorization 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 permit, consent, waiver, approval or authorization will be materially delayed; provided, for the avoidance of doubt, that neither party shall be required to disclose confidential supervisory information to the other party.

(f)Notwithstanding anything to the contrary in this Agreement, NIC shall be entitled to direct the defense of the transactions contemplated by this Agreement before any Governmental Entity and to control the scheduling of, and strategic planning for, any meetings with, and the conducting of negotiations with, Governmental Entities regarding any Requisite Regulatory Approvals consistent with this Section 6.1.

6.2 Access to Information; Confidentiality.

(a)Upon reasonable notice and subject to applicable laws, each of MOFG and NIC, for the purposes of enabling NIC and MOFG to verify the representations and warranties of the other party and preparing for the Mergers and the other matters contemplated by this

Agreement, shall, and shall cause its 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 both MOFG and NIC shall cooperate with the other party in preparing to execute after the Effective Time the conversion or consolidation of systems and business operations generally, and, during such period, MOFG and NIC shall, and shall cause its Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement or proxy 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 MOFG is not permitted to disclose in accordance with Section 9.14 or otherwise under applicable law), and (ii) all other information concerning its business, properties and personnel as such party may reasonably request. Neither NIC nor MOFG 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 NIC’s or MOFG’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 NIC and MOFG 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 Confidentiality and Non-Disclosure Agreement, dated August 25, 2025 by and between NIC and MOFG (as it may be amended in accordance with its terms, 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 in this Agreement.

6.3 Shareholders’ Approvals.

(a)Each of NIC and MOFG shall call a meeting of its shareholders (the “NIC Meeting” and the “MOFG Meeting”, respectively, and such meetings together, the “Meetings”) to be held as soon as reasonably practicable after the S-4 is declared effective, for the purpose of obtaining (a) in the case of NIC, the Requisite NIC Vote, and, in the case of MOFG, the Requisite MOFG Vote, (b) in the case of NIC, a vote to approve an amendment to the NIC Articles to increase the number of authorized shares of NIC Common Stock and a vote to approve the adoption of a new long-term equity incentive plan, and (c) if so desired and agreed by NIC and MOFG, a vote upon other matters of the type customarily brought before a meeting of shareholders in connection with the approval of a merger agreement or the transactions contemplated thereby. Each of NIC and MOFG shall use

its reasonable best efforts to cause such Meetings to occur on the same date. Subject to Section 6.3(b), each of NIC and MOFG and its respective Board of Directors shall use its reasonable best efforts to obtain from the shareholders of NIC and MOFG, as applicable, the Requisite NIC Vote and the Requisite MOFG Vote, as applicable, including by communicating to the respective shareholders of NIC and MOFG its respective recommendation (and including such recommendation in the Joint Proxy Statement) that, in the case of NIC, the shareholders of NIC approve this Agreement and the transactions contemplated hereby, including the issuance of shares of NIC Common Stock in the Merger (the “NIC Board Recommendation”), and, in the case of MOFG, the shareholders of MOFG approve this Agreement and the transactions contemplated hereby, including the Merger (the “MOFG Board Recommendation”). NIC, MOFG and their respective Boards of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the NIC Board Recommendation, in the case of NIC, or the MOFG Board Recommendation, in the case of MOFG, (ii) fail to make the NIC Board Recommendation, in the case of NIC, or the MOFG Board Recommendation, in the case of MOFG, 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 NIC Board Recommendation, in the case of NIC, or MOFG Board Recommendation, in the case of MOFG, in each case within 10 Business Days (or such fewer number of days as remains prior to the NIC Meeting or MOFG 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 actions described in clauses (i) through (v), a “Recommendation Change”) or (vi) execute or enter into any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement or other similar agreement (other than an Acceptable Confidentiality Agreement) providing for an Acquisition Proposal (an “Alternative Acquisition Agreement”).

(b)Notwithstanding anything in this Agreement to the contrary, subject to Section 8.1 and Section 8.2, prior to the receipt of the Requisite NIC Vote, in the case of NIC, or the Requisite MOFG Vote, in the case of MOFG, the Boards of Directors of NIC and MOFG, respectively, may effect a Recommendation Change, including submitting this Agreement to their respective shareholders without recommendation (which, for the avoidance of doubt, shall constitute a Recommendation Change), in which event the applicable Board of Directors may communicate the basis for its lack of recommendation to its shareholders in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law, if (i) (A) such Board of Directors has received after the date hereof a bona fide Acquisition Proposal which did not result from a breach of Section 6.13, which it determines in good faith, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisor(s), constitutes a Superior Proposal or (B) an Intervening Event has occurred and (ii) such Board of Directors, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisor(s), determines in good faith that the failure to take such action would be inconsistent with its fiduciary duties under applicable law, if, but only if, (1) NIC or MOFG, as applicable, has complied in all material respects with

Section 6.13, (2) NIC or MOFG, as applicable delivers to the other party at least four Business Days’ prior written notice of its intention to take such action, and furnishes to the other party a reasonable description of the events 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 identity of the person making such Acquisition Proposal, a copy of the proposed transaction agreement(s) and all other documents relating to such Acquisition Proposal), (3) prior to taking such action, such party negotiates, and causes its financial, legal, and other advisors to negotiate, in good faith with the other party, during the four Business Day period following such party’s delivery of the notice referred to in such sub-clause (2) above (to the extent the other party desires to so negotiate) any revision to the terms of this Agreement that the other party desires to propose, and (4) after the conclusion of such four Business Day period, the Board of Directors of NIC or the Board of Directors of MOFG, as applicable, determines in good faith, after giving effect to all of the adjustments or revisions (if any) which may be offered by the other party pursuant to sub-clause (3) above, that, in the case of actions described in clause (i)(A) above, such Acquisition Proposal continues to constitute a Superior Proposal and in case of actions described in either clause (i)(A) or clause (i)(B) above, would be inconsistent with its fiduciary duties under applicable law to make or continue to make the NIC Board Recommendation or MOFG Board Recommendation, as applicable (it being agreed that, if such actions are being taken in response to an Acquisition Proposal, in the event that, following delivery of the notice referred to in sub-clause (2) above, there is any material revision to the terms of such Acquisition Proposal, including any revision in price or other improvement in economic terms, the four Business Day period during which the parties agree to negotiate in good faith shall be extended, if applicable, to ensure that at least two Business Days remain to negotiate subsequent to the time MOFG notifies NIC of any such material revision (it being understood that there may be multiple extensions)). As used in this Agreement, the term “Intervening Event” means, in the case of NIC or MOFG, any material event, change, effect, development, condition, circumstance or occurrence arising after the date of this Agreement that is not known by, nor reasonably foreseeable to, the applicable Board of Directors of such party as of the date of this Agreement and does not relate to any Acquisition Proposal in respect of such party; provided; for the avoidance of doubt, none of the following shall be considered or taken into account in determining whether an Intervening Event has occurred: (x) changes in the trading price or trading volume of such party’s common stock (it being understood that the underlying cause of such change may be taken into account to the extent not otherwise excluded by this definition) or general developments or changes in the banking industry or in the credit, debt, financial or capital markets or in interest or exchange rates, (y) the fact alone that such party meets or exceeds any internal or published forecasts or projections for any period (it being understood that the underlying cause of such over-performance by such party may be taken into account to the extent not otherwise excluded by this definition) or (z) any event, change, effect, development, condition, circumstance or occurrence resulting from a breach of this Agreement by such party.

(c)Notwithstanding any Recommendation Change, unless this Agreement has been terminated, the MOFG Meeting and the NIC Meeting shall be convened and this Agreement shall be submitted to the shareholders of MOFG and NIC at such meetings for

the purpose of the shareholders of MOFG or NIC, as the case may be, considering and voting on approval of this Agreement and any other matters required to be approved by the shareholders of such party in order to consummate the transactions contemplated by this Agreement. Additionally, unless this Agreement has been terminated, neither NIC nor MOFG shall submit to or for a vote of its shareholders any Acquisition Proposal.

(d)Each of NIC and MOFG shall adjourn or postpone its Meeting if (i) as of the date of such Meeting there are insufficient shares of NIC Common Stock or MOFG Common Stock, as applicable, represented (either in person or by proxy) to constitute the quorum necessary to conduct the business of such Meeting, (ii) as of the date of such meeting NIC or MOFG, as applicable, has not received proxies representing a sufficient number of shares necessary for the approval of this Agreement by its shareholders, or (iii) required by applicable law in order to ensure that any required supplement or amendment to the Joint Proxy Statement required by applicable law is provided to the shareholders of NIC or MOFG, as applicable, a reasonable amount of time prior to such Meeting; provided that, in the case of clauses (i) and (ii), without the prior written consent of the other party, neither NIC nor MOFG, as applicable, shall adjourn or postpone its Meeting for more than five Business Days in the case of any individual adjournment or postponement or more than 20 Business Days in the aggregate.

6.4 Legal Conditions to Merger. Subject in all respects to Section 6.1 of this Agreement, each of NIC and MOFG 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 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 and the Bank Merger Agreement 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 MOFG or NIC or any of their respective Subsidiaries in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement and the Bank Merger Agreement.

6.5 Stock Exchange Listing. NIC shall cause the shares of NIC Common Stock to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time.

6.6 Employee Matters.

(a)From the Effective Time, NIC shall provide to each employee of MOFG and its Subsidiaries who at the Effective Time becomes an employee of the Surviving Entity or its Subsidiaries or who is on an approved leave of absence as of the Effective Time but returns to work thereafter (a “Continuing Employee”): (A) base salary or base wage; target annual cash bonus opportunities; target long-term incentive compensation opportunities; and employee benefits that are, in the aggregate, no less favorable than those made available to similarly situated employees of NIC and its Subsidiaries; provided that “employee benefits” shall exclude equity and equity-based compensation, long-term incentives, change in control or retention bonuses or benefits, defined benefit pension benefits, retiree medical benefits and severance benefits; and (B) except for

employees that are otherwise party to an employment, severance, change in control, or similar contract that provides for severance, severance benefits as set forth on Section 6.6(a) of the MOFG Disclosure Schedule, subject to such Continuing Employee’s execution, delivery and non-revocation of a general release in favor of MOFG, NIC and their respective Affiliates (including the Surviving Entity).

(b)For all purposes (including eligibility, participation, vesting and benefit accrual), except not for any purpose under any defined benefit pension plan, retiree medical plan or any frozen plan or to the extent that such credit would result in a duplication of benefits, under the NIC Benefit Plans, service with or credited by NIC, MOFG or any of their respective Subsidiaries or predecessors for Continuing Employees shall be treated as service with the Surviving Entity to the same extent that such service was taken into account under the analogous MOFG Benefit Plan prior to the Effective Time. With respect to any NIC Benefit Plan in which any Continuing Employees first become eligible to participate on or after the Effective Time, NIC shall use commercially reasonable efforts to (or cause its Subsidiary to): (A) waive all preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous MOFG Benefit Plan in which such employee participated immediately prior to the Effective Time; and (B) provide each such employee and his or her eligible dependents with credit for any co-payments and deductibles paid during the current NIC Benefit Plan year and prior to the Effective Time under a MOFG Benefit Plan (to the same extent that such credit was given under the analogous MOFG Benefit Plan in which such employee participated immediately prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under such NIC Benefit Plan, in each case, subject to NIC receiving all applicable information as reasonably requested by NIC, including information regarding pre-Closing co-payment and deductibles from MOFG.

(c)Unless otherwise notified by NIC in writing delivered to MOFG not less than 20 Business Days before the Closing Date, the Board of Directors of MOFG (or the appropriate committee or officers thereof) shall adopt resolutions and take such corporate action as is necessary or appropriate to terminate the MOFG 401(k) Plan (the “MOFG 401(k) Plan”), effective as of the day prior to the Closing Date and contingent upon the occurrence of the Effective Time. MOFG shall provide NIC with evidence that such plan has been terminated (the form and substance of which shall be subject to reasonable review and comment by NIC) not later than two days immediately preceding the Closing Date. Following the Effective Time, the Continuing Employees shall be eligible to participate in a 401(k) plan sponsored or maintained by NIC, the Surviving Entity or one of their Subsidiaries (the “NIC 401(k) Plan”). NIC and MOFG shall take any and all actions as may be required, including amendments to the MOFG 401(k) Plan and/or the NIC 401(k) Plan, to permit the Continuing Employees to make rollover contributions to the NIC 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 participant loans), or a combination thereof.

(d)Unless otherwise notified by NIC in writing delivered to MOFG not less than 20 Business Days before the Closing Date, at least 5 Business Days before the Closing Date, the Board of Directors of MOFG (or the appropriate committee or officers thereof) shall adopt resolutions and take such corporate action as is necessary or appropriate to terminate the MOFG 2023 Equity Incentive Plan and the MOFG 2017 Equity Incentive Plan, effective as of and contingent upon the occurrence of the Effective Time.

(e)If requested by NIC in writing delivered to MOFG not less than 20 Business Days before the Closing Date, the Board of Directors of MOFG (or the appropriate committee or officers thereof) shall adopt resolutions and take such corporate action as is necessary or appropriate to terminate the MOFG Benefit Plan(s) listed on MOFG Disclosure Schedule Section 3.11(b) to the extent and in the manner determined by NIC effective upon the Closing Date (or at such different time mutually agreed to by the parties) and consistent with applicable Law. If NIC requests such MOFG Benefit Plan(s) be terminated, MOFG shall provide NIC with evidence that such plan has been terminated (the form and substance of which shall be subject to reasonable review and comment by NIC) not later than two days immediately preceding the Closing Date.

(f)Nothing in this Agreement shall confer upon any employee, officer, director or consultant of NIC or MOFG or any of their Subsidiaries or Affiliates any right to continue in the employ or service of the Surviving Entity, MOFG, NIC or any Subsidiary or Affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Entity, MOFG, NIC or any Subsidiary or Affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of NIC or MOFG or any of their Subsidiaries or Affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any MOFG Benefit Plan or NIC Benefit Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Entity or any of its Subsidiaries or Affiliates to amend, modify or terminate any particular MOFG Benefit Plan or NIC Benefit 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 any current or former employee, officer, director or consultant of NIC or MOFG or any of their Subsidiaries or Affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a)From and after the Effective Time, the Surviving Entity shall indemnify and hold harmless and shall advance expenses as incurred, in each case, to the fullest extent permitted by applicable law, the MOFG Certificate, the MOFG Bylaws and the governing or organizational documents of any MOFG Subsidiary, each present and former director, officer or employee of MOFG and its Subsidiaries (in each case, when acting in such capacity at the time of the pertinent matter, act or omission) (collectively, the “MOFG Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities 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, or pertaining to, the fact that such person is or was a director, officer or employee of MOFG or any of its Subsidiaries and pertaining to matters, acts or omissions existing or occurring at or prior to the Effective Time, including matters, acts or omissions occurring in connection with the approval of this Agreement and the transactions contemplated by this Agreement; provided, that in the case of advancement of expenses, any MOFG Indemnified Party to whom expenses are advanced provides an irrevocable undertaking to repay such advances if it is ultimately determined that such MOFG Indemnified Party is not entitled to indemnification. The Surviving Entity shall reasonably cooperate with the MOFG Indemnified Parties, and the MOFG Indemnified Parties shall reasonably cooperate with the Surviving Entity, in the defense of any such claim, action, suit, proceeding or investigation. Without limiting the indemnification and other rights provided in this clause (a), nothing herein shall be interpreted to be less advantageous to the insured than the indemnification and other rights, including limitations on liability, existing in favor of the MOFG Indemnified Parties as provided in any indemnification agreement in existence on the date of this Agreement and set forth on Section 6.7 of the MOFG Disclosure Schedule.

(b)For a period of six years after the Effective Time, the Surviving Entity shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by MOFG (provided, that the Surviving Entity 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 MOFG or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time (including the approval of the transactions contemplated by this Agreement); provided, however, that the Surviving Entity 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 MOFG for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Entity shall cause to be maintained policies of insurance which, in the Surviving Entity’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, NIC or MOFG, in consultation with, but only upon the consent of, NIC, may (and at the request of NIC, MOFG shall use its reasonable best efforts to) obtain through an insurance broker acceptable to NIC, at or prior to the Effective Time, a six-year “tail” policy under MOFG’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 applicable to the entire six-year term of such coverage. If MOFG purchases such tail policy, the Surviving Entity shall maintain such tail policy in full force and effect and continue to honor its obligations thereunder.

(c)The obligations of the Surviving Entity, NIC or MOFG under this Section 6.7 shall not be terminated or modified after the Effective Time in a manner so as to adversely affect any MOFG Indemnified Party or any other person entitled to the benefit of this Section 6.7

without the prior written consent of the affected MOFG Indemnified Party or affected person.

(d)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 MOFG Indemnified Party and his or her heirs and representatives. If the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity 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 Entity shall cause proper provision to be made so that the successors and assigns of the Surviving Entity 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 NIC, on the one hand, and a Subsidiary of MOFG, on the other hand) or to vest the Surviving Entity 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 the Surviving Entity.

6.9 Advice of Changes. NIC and MOFG shall each promptly advise the other party of any effect, change, event, circumstance, condition, occurrence or development (i) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on such first party, or (ii) that such first party 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 in this Agreement 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.

6.10 Dividends. After the date of this Agreement, each of NIC and MOFG shall coordinate with the other the declaration of any dividends in respect of NIC Common Stock and MOFG Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that the holders of MOFG Common Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of MOFG Common Stock and any shares of NIC Common Stock any such holder receives in exchange therefor in the Merger.

6.11 Shareholder Litigation. Each party shall give the other party prompt notice of any shareholder litigation against such party or its directors or officers relating to the transactions contemplated by this Agreement. MOFG shall (i) give NIC the opportunity to participate (at NIC’s expense) in the defense or settlement of any such litigation, (ii) give NIC a reasonable opportunity to

review and comment on all filings or responses to be made by MOFG in connection with any such litigation, and will in good faith take such comments into account and (iii) not agree to settle any such litigation without NIC’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that the other party shall not be obligated to consent to any settlement which imposes an injunction or other equitable relief after the Effective Time upon the Surviving Entity or any of its Affiliates.

6.12 Board Representation. Prior to the Effective Time, the Board of Directors of NIC shall take all actions necessary so that the NIC Board of Directors is set at twelve members as of the Effective Time, consisting of (a) eight individuals selected by NIC from among the directors of NIC immediately prior to the Effective Time, and (b) four individuals selected by NIC from among the directors of MOFG immediately prior to the Effective Time.

6.13 Acquisition Proposals.

(a)Each party will, and will cause its 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 parties hereto with respect to any Acquisition Proposal. Each party agrees that it will not, and will cause each of its Subsidiaries not to, and will use its reasonable best efforts to cause 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 any 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 (except to notify a person that has made or, to the knowledge of such party, is making any inquiries with respect to, or is considering making, an Acquisition Proposal, of the existence of the provisions of this Section 6.13(a)), 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 similar agreement (whether written or oral, binding or nonbinding) (other than an Acceptable Confidentiality Agreement entered into in accordance with this Section 6.13) 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 NIC Vote, in the case of NIC, or the Requisite MOFG Vote, in the case of MOFG, a party receives an unsolicited bona fide written Acquisition Proposal that did not result from or arise in connection with a breach of this Section 6.13(a) by such party, 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 outside counsel and, with respect to financial matters, financial advisor(s)) that failure to take such actions would be inconsistent with 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 provided such information to the other party and shall

have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to such party than the Confidentiality Agreement (“Acceptable Confidentiality Agreement”), which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. Each party will promptly (within 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 in connection with any 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” shall mean, with respect to a party, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of such party and its Subsidiaries or 25% or more of any class of equity or voting securities of such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party, (ii) 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 such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party. As used in this Agreement, “Superior Proposal” shall mean, with respect to a party, any bona fide written Acquisition Proposal which the Board of Directors of such party determines, in good faith, after taking into account all legal, financial, regulatory, and other aspects of such proposal (including the amount, form, and timing of payment of consideration, the financing thereof, any associated break-up or termination fees, including those provided for in this Agreement, expense reimbursement provisions, and all conditions to consummation) and the person making the proposal, and after consulting with its financial advisor (which shall be a nationally recognized investment banking firm) and outside legal counsel, is (i) more favorable from a financial point of view to such party’s shareholders than the transactions contemplated by this Agreement (taking into account any proposal by the other party to amend the terms of this Agreement pursuant to Section 6.3(b)) and (ii) if accepted, reasonably likely to be timely consummated on the terms set forth; provided, however, that for purposes of this definition of Superior Proposal, references to “25%” in the definition of Acquisition Proposal shall be deemed to be references to “50%.” It is agreed that any violation of the restrictions on a party set forth in this Section 6.13(a) by any officer, director, employee, consultant, advisor or other representative of such party or any of its Subsidiaries, in each case acting on behalf of

such party or any of its Subsidiaries, shall be a breach of this Section 6.13(a) by such party.

(b)Nothing contained in this Agreement shall prevent a party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act or Item 1012(a) of Regulation M-A with respect to an Acquisition Proposal or from making any legally required disclosure to such party’s shareholders; 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.

6.14 Public Announcements. MOFG and NIC 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 (i) 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, (ii) for such releases, announcements or statements that provide no more information than disclosed in and are consistent with other such releases, announcements or statements made prior thereto in compliance with this Section 6.14, (iii) with respect to any Acquisition Proposal or Superior Proposal (subject to Section 6.3 and Section 6.13) or (iv) for statements that are reasonably necessary in connection with a party enforcing its rights under this Agreement in any litigation between the parties relating to this Agreement. It is understood that NIC shall assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Mergers and the other transactions contemplated hereby.

6.15 Change of Method. NIC shall be empowered, at any time prior to the Effective Time, to change the method or structure of effecting the combination of MOFG and NIC (including the provisions of Article I), if and to the extent the Board of Directors of NIC deems such change to be necessary, appropriate or desirable; provided, that unless this Agreement is amended by agreement of each party in accordance with Section 9.1, no such change shall (i) alter or change the Exchange Ratio or the number of shares of NIC Common Stock received by holders of MOFG Common Stock in exchange for each share of MOFG Common Stock, (ii) otherwise adversely affect the economic effect on holders of NIC Common Stock or MOFG Common Stock, (iii) adversely affect the Tax treatment of MOFG’s shareholders pursuant to this Agreement, (iv) adversely affect the Tax treatment of MOFG or NIC pursuant to this Agreement or (v) 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 9.1.

6.16 Takeover Statutes. Neither party nor its Board 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 their respective

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 MOFG Indebtedness. At and after the Effective Time, NIC shall assume the due and punctual performance and observance of the covenants to be performed by MOFG under the indentures set forth on Section 6.17 of the MOFG Disclosure Schedule, and the due and punctual payment of the principal of (and premium, if any) and interest on, the notes governed thereby. In connection therewith, prior to the Effective Time, NIC and MOFG shall cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, officer’s certificates or other documents, and the parties hereto shall cooperate and use reasonable best efforts to provide any opinion of counsel to the trustee thereof required to make such assumption effective as of the Effective Time.

6.18 Exemption from Liability Under Section 16(b). MOFG and NIC agree that, in order to most effectively compensate and retain MOFG Insiders, both prior to and after the Effective Time, it is desirable that MOFG Insiders 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 cancellation or conversion of shares of MOFG Common Stock and MOFG Equity Awards into shares of NIC Common Stock in the Merger and for that compensatory and retentive purposes agree to the provisions of this Section 6.18. MOFG shall deliver to NIC in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of MOFG subject to the reporting requirements of Section 16(a) of the Exchange Act (the “MOFG Insiders”), and the Board of Directors of NIC and of MOFG, 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 MOFG) any dispositions of MOFG Common Stock or MOFG Equity Awards by the MOFG Insiders, and (in the case of NIC) any acquisitions of NIC Common Stock by any MOFG Insiders who, immediately following the Merger, will be officers or directors of the Surviving Entity 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.

6.19 Certain Tax Matters. Each of MOFG and NIC shall use its reasonable best efforts to cause the Merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Each of MOFG and NIC shall use its reasonable best efforts and shall cooperate with one another to obtain the opinion of counsel referred to in Section 7.2(c) and Section 7.3(c). In connection with the foregoing, (a) MOFG shall deliver to the counsel that is delivering the opinion referred to in Section 7.2(c) and Section 7.3(c) a duly executed letter of representations customary for transactions of this type and reasonably satisfactory to either such counsel (the “MOFG Tax Certificate”), and (b) NIC shall deliver to the counsel that is delivering the opinion referred to in Section 7.2(c) and Section 7.3(c) a duly executed letter of representations customary for transactions of this type and reasonably satisfactory to either such counsel (the “NIC Tax Certificate”), in the case of each of clauses (a) and (b), at such times as either such counsel shall reasonably request.

6.20 Coordination; Informational Systems Conversion; Operating Functions.

(a)From and after the date hereof, NIC and MOFG will use their commercially reasonable efforts to facilitate the integration of MOFG with the business of NIC following consummation of the transactions contemplated hereby. MOFG shall permit representatives of NIC to be onsite at MOFG or MOFG Bank to facilitate integration of operations and assist with any other coordination efforts as necessary, provided such efforts shall be done without undue disruption to MOFG Bank’s business, during normal business hours and at the expense of NIC or Nicolet Bank (not to include MOFG Bank’s regular employee payroll).

(b)Prior to the Effective Time, subject to applicable laws, MOFG and its Subsidiaries shall take any actions NIC may reasonably request in connection with negotiating any amendments, modifications or terminations of any leases or MOFG Material Contracts that NIC may request, including, but not limited to, actions necessary to cause any such amendments, modifications or terminations to become effective prior to (to the extent that the conditions set forth in Article VII of this Agreement have already been satisfied), or immediately upon, the Closing, and shall cooperate with NIC and will use its commercially reasonable efforts to negotiate specific provisions that may be requested by NIC in connection with any such amendment, modification or termination.

(c)From and after the date hereof, senior officers of NIC and MOFG shall meet on a regular basis to discuss and plan for the conversion of the data processing and related electronic informational systems of MOFG and each of its Subsidiaries (the “Informational Systems Conversion”) to such systems designated by NIC, which planning shall include, but not be limited to, (a) discussion of third-party service provider arrangements of MOFG and each of its Subsidiaries; (b) non-renewal or changeover, after the Effective Time, of personal property leases and software licenses used by MOFG and each of its Subsidiaries in connection with the systems operations; (c) retention of outside consultants and additional employees to assist with the conversion; (d) outsourcing, as appropriate after the Effective Time, of proprietary or self-provided system services; and (e) any other actions necessary and appropriate to facilitate the conversion, as soon as practicable following the Effective Time.

(d)MOFG and MOFG Bank shall cooperate with NIC and Nicolet Bank in connection with planning for the efficient and orderly combination of the operations of MOFG Bank and Nicolet Bank, and in preparing for the consolidation of the banks’ appropriate operating functions to be effective upon consummation of the Bank Merger, including the potential merger of MidWestOne Foundation with and into Nicolet National Foundation and the assignment of rights and responsibilities of IBAK & Co. Without limiting the foregoing, MOFG shall provide reasonably requested support services (and other reasonably requested support and assistance) in connection with the foregoing, and senior officers of MOFG and NIC shall meet from time to time as MOFG or NIC may reasonably request, to review the financial and operational affairs of MOFG and MOFG Bank, and MOFG shall give due consideration to NIC’s input on such matters, with the understanding that, notwithstanding any other provision contained in this Agreement: (a) neither NIC nor Nicolet Bank shall under any circumstance be permitted to exercise control of MOFG, MOFG Bank, or any of MOFG’s other Subsidiaries prior to the Effective Time; (b)

neither MOFG nor any of its Subsidiaries shall be under any obligation to act in a manner that could reasonably be deemed to constitute anti-competitive behavior under federal or state antitrust laws; and (c) neither MOFG nor any of its Subsidiaries shall be required to agree to any material obligation that is not contingent upon the consummation of the Merger.

(e)NIC shall promptly reimburse MOFG on request for any reasonable and documented out-of-pocket fees, expenses or charges that MOFG may incur at the request of NIC pursuant to this Section 6.20.

6.21 Claims Letters. Concurrently with the execution and delivery of this Agreement and effective upon the Closing, MOFG has caused each director of MOFG and MOFG Bank to execute and deliver the Claims Letter in the form attached hereto as Exhibit D.

(e)(i) In the event that this Agreement is terminated by NIC pursuant to Section 8.1(e) (MOFG Recommendation Change) or by MOFG or NIC pursuant to Section 8.1(c) (Termination Date) or Section 8.1(g)(i) (MOFG No Vote), in each case, at a time when this Agreement was terminable by NIC pursuant to Section 8.1(e) (MOFG Recommendation Change), then MOFG shall pay NIC, by wire transfer of same-day

funds, the MOFG Termination Fee within two Business Days of the date of termination or (ii) in the event that this Agreement is terminated by MOFG pursuant to Section 8.1(f) (NIC Recommendation Change) or by MOFG or NIC pursuant to Section 8.1(c) (Termination Date) or Section 8.1(g)(ii) (NIC No Vote), in each case, at a time when this Agreement was terminable by NIC pursuant to Section 8.1(f) (NIC Recommendation Change), then NIC shall pay MOFG, by wire transfer of same-day funds, the MOFG Termination Fee within two Business Days of the date of termination.

(f)Notwithstanding anything to the contrary in this Agreement, but without limiting the right of any party to recover liabilities or damages arising out of the other party’s Fraud or willful and material breach of any provision of this Agreement, in no event shall either party be required to pay the MOFG Termination Fee or NIC Termination Fee, as applicable, more than once.

(g)Each of NIC and MOFG 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 a party fails promptly to pay any amount due pursuant to this Section 8.2, and, in order to obtain such payment, NIC commences a suit which results in a judgment against the non-paying party for the MOFG Termination Fee or NIC Termination Fee, as applicable, or any portion thereof, such non-paying party shall pay the reasonable costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit. In addition, if a party fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts 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.

9.11 Assignment; Third-Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other party. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. This Agreement (including the documents and instruments referred to herein) is not intended to, and does not, confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth in this Agreement, except (a) as otherwise specifically provided in Section 6.7, which is intended to benefit each MOFG Indemnified Party, and (b) the rights of MOFG, on behalf of the MOFG shareholders (each of which are third party beneficiaries of this Agreement to the extent required for this provision to be enforceable), and the rights of NIC, on behalf of the NIC shareholders (each of which are third party beneficiaries of this Agreement to the extent required for this provision to be enforceable), to pursue specific performance as set forth in Section 9.12 or, if specific performance is not sought or granted as a remedy, damages (including damages based on the loss of the benefits of the transactions contemplated by this Agreement to such shareholders, including, in the case of MOFG, the loss of the premium (if any) to which the shareholders of MOFG would have been entitled) in accordance with Section 8.2 in the event of Fraud or willful and material breach of any provision of this Agreement, it being agreed that in no event shall any MOFG or NIC shareholder be entitled to enforce any of their rights, or any of the party’s obligations, under this Agreement directly in the event of any such breach, but rather that (i) MOFG shall have the sole and exclusive right to do so in its sole and absolute discretion, as agent for the MOFG shareholders, and (ii) NIC shall have the sole and exclusive right to do so in its sole and absolute discretion, as agent for the NIC shareholders, and MOFG or NIC, as applicable, may retain any amounts obtained in connection therewith. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

9.12 Specific Performance. The parties hereto agree that irreparable damage, for which monetary damages (even if available) would not be an adequate remedy, would occur if any provision of this Agreement were not performed in accordance with the terms hereof and, accordingly, that the parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Merger), in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate, and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.

9.13 Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

9.14 Confidential Supervisory Information. Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information (including confidential supervisory information as defined in 12 C.F.R. § 261.2(c) and as identified in 12 C.F.R. § 309.5(g)(8)) of a Governmental Entity by any party to this Agreement to the extent prohibited by applicable law. To the extent legally permissible, appropriate substitute disclosures or actions shall be made or taken under circumstances in which the limitations of the preceding sentence apply.

9.15 Delivery by Electronic Transmission. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by e-mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall raise the use of e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each party hereto forever waives any such defense.

Exhibit A

FORM OF MOFG SUPPORT AGREEMENT

THIS SUPPORT AGREEMENT (this “Agreement”) is dated as of October 23, 2025, by and between the undersigned holder (“Shareholder”) of capital stock of MidWestOne Financial Group, Inc., an Iowa corporation (“MOFG”), and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇, Inc., a Wisconsin corporation (“NIC”). All capitalized terms used but not defined herein shall have the meanings assigned to them in the Merger Agreement (defined below).

RECITALS:

WHEREAS, concurrently with the execution of this Agreement, NIC and MOFG are entering into an Agreement and Plan of Merger (as such agreement may be subsequently amended or modified, the “Merger Agreement”), pursuant to which (i) MOFG will merge with and into NIC, with NIC as the surviving entity, and (ii) MidWestOne Bank, an Iowa state-chartered bank and a direct wholly-owned subsidiary of MOFG, will merge with and into Nicolet National Bank, a national banking association and a direct wholly owned subsidiary of NIC, with Nicolet National Bank as the surviving bank (collectively, the “Merger”), and in connection with the Merger, each issued and outstanding share of MOFG Common Stock immediately prior to the Effective Time (except for shares of MOFG Common Stock owned by MOFG or NIC (in each case, other than shares of MOFG 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 MOFG or NIC in respect of debts previously contracted)) will be converted into and exchanged for the right to receive the Merger Consideration and cash in lieu of fractional shares.

WHEREAS, Shareholder “beneficially owns” (as such term is defined in Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) and is entitled to dispose of (or direct the disposition of) and to vote (or direct the voting of) directly or indirectly the number of shares of MOFG Common Stock indicated on the signature page of this Agreement under the heading “Number of Shares of MOFG Common Stock Subject to this Agreement;” provided that such shares do not include shares beneficially owned by Shareholder but subject to the voting direction of a third party with regard to voting on the Merger (such shares, together with any additional shares of MOFG Common Stock subsequently acquired by Shareholder during the term of this Agreement, including through the exercise of any stock option or other equity award, warrant or similar instrument, being referred to collectively as the “Shares”); and

WHEREAS, it is a material inducement to the willingness of NIC to enter into the Merger Agreement that Shareholder execute and deliver this Agreement.

AGREEMENT:

NOW, THEREFORE, in consideration of, and as a material inducement to, NIC entering into the Merger Agreement and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by NIC in connection therewith, Shareholder and NIC agree as follows:

Exhibit A-1

Section 1. Agreement to Vote Shares. Shareholder agrees that, while this Agreement is in effect, at any meeting of shareholders of MOFG, however called, or at any adjournment thereof, or in any other circumstances in which Shareholder is entitled to vote, consent or give any other approval, except as otherwise agreed to in writing in advance by NIC, Shareholder shall:

(a)appear at each such meeting in person or by proxy or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b)vote (or cause to be voted), in person or by proxy, all the Shares as to which the Shareholder, directly or indirectly, controls the right to vote or direct the voting, and shall use Shareholder’s reasonable efforts to cause to be voted all the Shares as to which the Shareholder has, directly or indirectly, shared voting authority (i) in favor of adoption and approval of the Merger Agreement and the consummation of the transactions contemplated thereby (including any amendments or modifications of the terms thereof approved by the board of directors of MOFG and adopted in accordance with the terms thereof); (ii) in favor of any proposal to adjourn or postpone such meeting, if necessary, to solicit additional proxies to approve the Merger Agreement; (iii) against any action or agreement that would reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of MOFG contained in the Merger Agreement or of Shareholder contained in this Agreement; and (iv) against any Acquisition Proposal or any other action, agreement or transaction that is intended, or could reasonably be expected, to materially impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the transactions contemplated by the Merger Agreement or this Agreement.

Shareholder further agrees not to vote or execute any written consent to rescind or amend in any manner any prior vote or written consent, as a shareholder of MOFG, to approve or adopt the Merger Agreement unless this Agreement shall have been terminated in accordance with its terms.

Section 2. No Inconsistent Agreements. Shareholder hereby covenants and agrees that, except for this Agreement, Shareholder (a) shall not enter into, at any time while this Agreement remains in effect, any voting agreement or voting trust or any other contract with respect to the Shares, (b) shall not grant at any time while this Agreement remains in effect, a proxy (other than as required to effect Shareholder’s voting obligations in Section 1), consent or power of attorney in contravention of the obligations of Shareholder under this Agreement with respect to the Shares, (c) shall not commit any act, except for transfers permitted under Section 3, that could restrict or affect his or her legal power, authority and right to vote any of the Shares then held of record or beneficially owned by Shareholder or otherwise reasonably expected to prevent or disable Shareholder from performing any of his or her obligations under this Agreement, and (d) shall not take any action that would reasonably be expected to make any representation or warranty of Shareholder contained herein untrue or incorrect or have the effect of materially impeding, preventing, delaying, interfering with, disabling or adversely affecting the performance by, Shareholder of his or her obligations under this Agreement.

Section 3. No Transfers. Until the earlier of (i) the termination of this Agreement pursuant to Section 7 and (ii) receipt of the Requisite MOFG Vote, Shareholder agrees not to, directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other

Exhibit A-2

disposition of, any of the Shares, except the following transfers shall be permitted: (a) transfers by will or operation of Law, in which case this Agreement shall bind the transferee, (b) transfers pursuant to any pledge agreement, subject to the pledgee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement, (c) transfers in connection with estate and tax planning purposes, including transfers to relatives, trusts and charitable organizations, subject to each transferee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement, (d) transfers to an entity controlled by such Shareholder,and (e) such transfers as NIC may otherwise permit in its sole discretion. Any transfer or other disposition in violation of the terms of this Section 3 shall be null and void; provided, however, the pledges disclosed in Schedule A that are in effect as of the date hereof to a lender of the undersigned, and bona fide transactions under such pledges are permitted.

Section 4. Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with ▇▇▇ as follows:

(a)Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement.

(b)This Agreement has been duly executed and delivered by Shareholder, and assuming the due authorization, execution and delivery by NIC, constitutes a valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(c)The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject or, in the event that Shareholder is a corporation, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder.

(d)Shareholder is the beneficial owner of, or is the trustee that is the record holder of, and whose beneficiaries are the beneficial owners of, and has good title to all of the Shares, and, except for pledges set forth on Schedule A, the Shares are owned free and clear of any liens, security interests, charges or other encumbrances. The Shares do not include shares over which Shareholder exercises control in a fiduciary capacity for any other person or entity that is not an Affiliate of Shareholder, and no representation by Shareholder is made with respect thereto. Shareholder has the right to vote, or direct the voting of, the Shares, and none of the Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement. Shareholder does not own, of record or beneficially, any shares of capital stock of MOFG other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock.

Exhibit A-3

Section 5. No Solicitation and Non-Disparagement. From and after the date hereof until the termination of this Agreement pursuant to Section 7, Shareholder, in his, her or its capacity as a shareholder of MOFG, shall not, nor shall such Shareholder authorize any partner, officer, director, advisor or representative of, such Shareholder or any of his, her or its Affiliates to, directly or indirectly (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to prohibit any of his, her or its representatives or Affiliates to), (a) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (b) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any person (other than NIC) any information or data with respect to MOFG or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle or letter of intent with respect to an Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal, (d) solicit proxies with respect to an Acquisition Proposal (other than the Merger Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement, (e) initiate a shareholders’ vote or action by consent of MOFG’s shareholders with respect to an Acquisition Proposal or (f) make, publish or communicate any negative, defamatory or disparaging statements, remarks or comments concerning or alluding to MOFG, NIC, MidWestOne Bank, Nicolet National Bank or their products, customers, suppliers, licensees, licensors, franchisees or employees, except, in each case, in his capacity as a director or officer of MOFG and under circumstances for which such actions are permitted for MOFG under the Merger Agreement.

Section 6. Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of NIC to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to NIC if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, NIC will not have an adequate remedy at law or in equity. Accordingly, ▇▇▇▇▇▇▇▇▇▇▇ agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that NIC has an adequate remedy at Law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with NIC’s seeking or obtaining such equitable relief. In addition, after discussing the matter with Shareholder, NIC shall have the right to inform any third party that NIC reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of ▇▇▇ ▇▇▇▇▇▇▇▇▇, and that participation by any such persons with Shareholder in activities in violation of Shareholder’s agreement with NIC set forth in this Agreement may give rise to claims by NIC against such third party.

Section 7. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the mutual written agreement of the parties hereto, and shall be automatically terminated upon the earlier to occur of (a) the Effective Time, (b) the amendment of the Merger Agreement in any manner that materially and adversely affects any of Shareholder’s rights set forth therein (including, for the avoidance of doubt, any reduction to the Merger Consideration), (c) termination of the Merger Agreement or (d) two (2) years from the date hereof. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however,

Exhibit A-4

that such termination shall not relieve any party from liability for any breach of this Agreement prior to such termination.

Section 8. Entire Agreement. This Agreement represents the entire understanding of the parties hereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made.

Section 9. Modification and Waiver. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by each party. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of dissimilar provisions or conditions at the same or any prior subsequent time.

Section 10. Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the parties shall use their commercially reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

Section 11. Capacity as Shareholder. This Agreement shall apply to Shareholder solely in his, her or its capacity as a shareholder of MOFG and it shall not apply in any manner to Shareholder in his, her or its capacity as a director or officer of MOFG or a fiduciary of any trust in which Shareholder is not the sole beneficiary, if applicable. Nothing contained in this Agreement shall be deemed to apply to, limit or otherwise affect in any manner, the obligations of Shareholder to comply with his, her or its fiduciary duties as a director or officer of MOFG or a fiduciary of any trust in which Shareholder is not the sole beneficiary, if applicable.

Section 12. Governing Law. This Agreement shall be governed by, and interpreted and enforced in accordance with, the internal, substantive laws of the State of Wisconsin, without regard for conflict of law provisions.

Section 13. Jurisdiction. Any civil action, counterclaim, proceeding or litigation arising out of or relating to this Agreement shall be brought in any federal or state courts of competent jurisdiction in the State of Wisconsin. Each party consents to the jurisdiction of such Wisconsin court in any such civil action, counterclaim, proceeding or litigation and waives any objection to the laying of venue of any such civil action, counterclaim, proceeding or litigation in such Wisconsin court. Service of any court paper may be effected on such party by mail, as provided in this letter, or in such other manner as may be provided under applicable Laws.

Section 14. WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES

Exhibit A-5

AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 14.

Section 15. Waiver of Appraisal Rights; Further Assurances. To the extent permitted by applicable law, Shareholder hereby waives any rights of appraisal or rights to dissent from the Merger or demand fair value for his, her or its Shares in connection with the Merger, in each case, that Shareholder may have under applicable law. From time to time prior to the termination of this Agreement, at NIC’s request and without further consideration, Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the transactions contemplated by this Agreement. Shareholder further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against NIC, Nicolet National Bank, MOFG, MidWestOne Bank or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger.

Section 16. Disclosure. Shareholder hereby authorizes MOFG and NIC to publish and disclose in any announcement or disclosure required by the Securities and Exchange Commission and in the S-4 and the Joint Proxy Statement such Shareholder’s identity and ownership of the Shares and the nature of Shareholder’s obligations under this Agreement; provided, however, that NIC shall provide Shareholder written drafts of any such disclosure and consider in good faith Shareholder’s comments thereto.

Section 17. Ownership. Nothing in this Agreement shall be construed to give NIC any rights to exercise or direct the exercise of voting power as owner of the Shares or to vest in NIC any direct or indirect ownership or incidents of ownership of or with respect to any of the Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, notwithstanding the provisions of this Agreement, and NIC shall have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of MOFG or to exercise any power or authority to direct the Shareholder in voting any of the Shares, except as otherwise expressly provided herein.

Section 18. Counterparts. This Agreement may be executed and delivered by facsimile or by electronic data file and in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the same counterpart. Signatures delivered by facsimile or by electronic data file shall have the same effect as originals.

(a)appear at each such meeting in person or by proxy or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

Any transfer or other disposition in violation of the terms of this Section 3 shall be null and void; provided, however, the pledges disclosed in Schedule A that are in effect as of the date hereof to a lender of the undersigned, and bona fide transactions under such pledges are permitted.

Section 4. Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with MOFG as follows:

(a)Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement.

(b)This Agreement has been duly executed and delivered by Shareholder, and assuming the due authorization, execution and delivery by MOFG, constitutes a valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(d)Shareholder is the beneficial owner of, or is the trustee that is the record holder of, and whose beneficiaries are the beneficial owners of, and has good title to all of the Shares, and, except for pledges set forth on Schedule A, the Shares are owned free and clear of any liens, security interests, charges or other encumbrances. The Shares do not include shares over which Shareholder exercises control in a fiduciary capacity for any other person or entity that is not an Affiliate of Shareholder, and no representation by Shareholder is made with respect thereto. Shareholder has the right to vote, or direct the voting of, the Shares, and none of the Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement. Shareholder does not own, of record or beneficially, any shares of capital stock of NIC other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock.

Exhibit B-3

Section 5. No Solicitation and Non-Disparagement. From and after the date hereof until the termination of this Agreement pursuant to Section 7, Shareholder, in his, her or its capacity as a shareholder of NIC, shall not, nor shall such Shareholder authorize any partner, officer, director, advisor or representative of, such Shareholder or any of his, her or its Affiliates to, directly or indirectly (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to prohibit any of his, her or its representatives or Affiliates to), (a) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (b) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any person (other than MOFG) any information or data with respect to NIC or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle or letter of intent with respect to an Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal, (d) solicit proxies with respect to an Acquisition Proposal (other than the Merger Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement, (e) initiate a shareholders’ vote or action by consent of NIC’s shareholders with respect to an Acquisition Proposal or (f) make, publish or communicate any negative, defamatory or disparaging statements, remarks or comments concerning or alluding to MOFG, NIC, MidWestOne Bank, Nicolet National Bank or their products, customers, suppliers, licensees, licensors, franchisees or employees, except, in each case, in his capacity as a director or officer of NIC and under circumstances for which such actions are permitted for NIC under the Merger Agreement.

Section 6. Specific Performance; Remedies; Attorneys’ Fees. Shareholder acknowledges that it is a condition to the willingness of MOFG to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to MOFG if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, MOFG will not have an adequate remedy at law or in equity. Accordingly, ▇▇▇▇▇▇▇▇▇▇▇ agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that MOFG has an adequate remedy at Law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with MOFG’s seeking or obtaining such equitable relief. In addition, after discussing the matter with Shareholder, MOFG shall have the right to inform any third party that MOFG reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of MOFG hereunder, and that participation by any such persons with Shareholder in activities in violation of Shareholder’s agreement with MOFG set forth in this Agreement may give rise to claims by MOFG against such third party.

Section 7. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the mutual written agreement of the parties hereto, and shall be automatically terminated upon the earlier to occur of (a) the Effective Time, (b) the amendment of the Merger Agreement in any manner that materially and adversely affects any of Shareholder’s rights set forth therein (including, for the avoidance of doubt, any increase to the Merger Consideration), (c) termination of the Merger Agreement or (d) two (2) years from the date hereof. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however,

Exhibit B-4

that such termination shall not relieve any party from liability for any breach of this Agreement prior to such termination.

Section 11. Capacity as Shareholder. This Agreement shall apply to Shareholder solely in his, her or its capacity as a shareholder of NIC and it shall not apply in any manner to Shareholder in his, her or its capacity as a director or officer of NIC or a fiduciary of any trust in which Shareholder is not the sole beneficiary, if applicable. Nothing contained in this Agreement shall be deemed to apply to, limit or otherwise affect in any manner, the obligations of Shareholder to comply with his, her or its fiduciary duties as a director or officer of NIC or a fiduciary of any trust in which Shareholder is not the sole beneficiary, if applicable.

Exhibit B-5

Section 15. Waiver of Appraisal Rights; Further Assurances. To the extent permitted by applicable law, Shareholder hereby waives any rights of appraisal or rights to dissent from the Merger or demand fair value for his, her or its Shares in connection with the Merger, in each case, that Shareholder may have under applicable law. From time to time prior to the termination of this Agreement, at MOFG’s request and without further consideration, Shareholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to effect the actions and consummate the transactions contemplated by this Agreement. Shareholder further agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against NIC, Nicolet National Bank, MOFG, MidWestOne Bank or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger.

Section 16. Disclosure. Shareholder hereby authorizes MOFG and NIC to publish and disclose in any announcement or disclosure required by the Securities and Exchange Commission and in the S-4 and the Joint Proxy Statement such Shareholder’s identity and ownership of the Shares and the nature of Shareholder’s obligations under this Agreement; provided, however, that MOFG shall provide Shareholder written drafts of any such disclosure and consider in good faith Shareholder’s comments thereto.

Section 17. Ownership. Nothing in this Agreement shall be construed to give MOFG any rights to exercise or direct the exercise of voting power as owner of the Shares or to vest in MOFG any direct or indirect ownership or incidents of ownership of or with respect to any of the Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, notwithstanding the provisions of this Agreement, and MOFG shall have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of NIC or to exercise any power or authority to direct the Shareholder in voting any of the Shares, except as otherwise expressly provided herein.

No waiver, amendment, modification or change of any provision of this Agreement shall be effective unless and until made in writing and signed by the Banks. No waiver, forbearance or failure by any Bank of its rights to enforce any provision of this Agreement shall constitute a waiver or estoppel of such Bank’s right to enforce any other provision of this Agreement or a continuing waiver by such Bank of compliance with any provision hereof.

Except to the extent Federal law is applicable, this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Wisconsin without regard to principles of conflicts of laws.

This Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Banks’ respective successors and permitted assigns.
