ARTICLE I
THE MERGER

(b)Subject to the written consent of Company, which shall not be unreasonably withheld or delayed, Buyer may at any time change the method of effecting the combination (including by providing for the merger of a wholly owned subsidiary of Buyer with Company) if and to the extent requested by Buyer; provided, however, that no such change or amendment shall (i) alter or change the amount or kind of the Merger Consideration (as defined in Section 1.4(b)) to be received by the shareholders of Company, (ii) adversely affect the tax consequences of the Merger to the shareholders of Company or the tax treatment of either Party pursuant to this Agreement, or (iii) impede or materially delay consummation of the transactions contemplated by this Agreement.

(a)Each share of common stock, $0.125 stated value, of Buyer, (“Buyer Common Stock”) issued and outstanding immediately prior to the Effective Time shall remain outstanding and continue to be one validly issued, fully paid and nonassessable share of common stock, $0.125 stated value, of the Surviving Company.

(b)Subject to the allocation and election procedures set forth in Article II, the adjustment, if any, pursuant to Section 1.4(c) and the payment of cash in lieu of fractional shares as provided in Section 2.8, each share of common stock, $1.00 par value, of Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time, excluding Cancelled Shares (as defined in Section 1.4(d) and Dissenting Shares (as defined in Section 1.4(g)), but including Trust Account Common Shares and DPC Common Shares (as such terms are defined in Section 1.4(d)), shall be converted into the right to receive either (i) 0.5727 shares (the “Exchange Ratio”) of Buyer Common Stock (the “Stock Consideration”), or (ii) immediately available funds equal to Forty-Four Dollars and Thirty-Five Cents ($44.35) (the

​

“Cash Consideration”). The applicable Stock Consideration or Cash Consideration, in each case without interest, is referred to in this Agreement as the “Merger Consideration”.

​

(c)In the event that the Company Adjusted Consolidated Shareholders’ Equity as of the close of business on the Closing Date shall be less than Eighty-Two Million Four Hundred Thirty-Seven Thousand Eight Hundred Twenty-Six Dollars ($82,437,826), the Merger Consideration shall be adjusted downward on a dollar-for-dollar basis in the amount of such shortfall. Company shall deliver to Buyer no later than five (5) business days prior to the scheduled Closing Date a written estimate of the Company Adjusted Consolidated Shareholders’ Equity.

(i)For purposes of this Agreement, “Company Adjusted Consolidated Shareholders’ Equity” shall be an estimate of the “total equity capital” of Company, calculated in the manner as reported on Schedule SC – Balance Sheet, Item 16(f), of the Parent Company Only Financial Statements for Small Holding Companies – FR Y-9SP, as of the close of business on the Closing Date to the reasonable satisfaction of Buyer, including the recognition of or accrual for all federal, state, local and foreign taxes for all periods ending on or prior to the close of business on the Closing Date.

(ii)Notwithstanding Section 1.4(c)(i), the following matters in each case accrued, incurred or to be incurred by Company or Company Bank through the Effective Time and undertaken in connection with this Agreement and the transactions contemplated hereby, will not reduce or impact the calculation of the Company Adjusted Consolidated Shareholders’ Equity for purposes of this Section 1.4: (A) the recognition of or accrual for all expenses paid or incurred or projected to be paid or incurred in connection with this Agreement and the Merger, including, without limitation, any fees or expenses of attorneys, accountants, consultants, financial advisor, investment bankers, and other professional advisors (including advisors with respect to services related to Section 280G of the Code); (B) the recognition of or accrual for all expenses paid of incurred or projected to be paid or incurred in connection with the MidCo Merger (as defined in Section 6.14), including franchise taxes and filing fees associated  therewith; (C) any accruals established or changes made pursuant to Section 6.12; (D) changes in accumulated other comprehensive income (loss) on available for sale securities from June 30, 2026 through the Closing Date; (E) the reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) paid or payable in connection with successfully enforcing any provision or provisions of the Agreement against Buyer (whether by litigation, arbitration, mediation, settlement or negotiation); (F) the recognition of or accrual for all contributions, premiums, or other payments owed under any (i) employment agreement, change in control agreement, retention or stay bonus agreements, termination agreement or similar agreements as set forth on Section 3.14(a)(i), Section 5.2(e) and Section 6.5(d)(i) of the Company Disclosure Schedule, including all Company SARs, Company Stock Options, or any other equity or equity based awards or (ii) Company Benefit Plan or employee policy of the Company or its Subsidiaries; (G) costs associated with the termination of Company Benefit Plans; (H) costs associated with the purchase of officers’ and directors’ liability insurance coverage pursuant to Section 6.6(a); and (I) any costs associated with the termination of

​

Company’s and any of its Subsidiaries’ agreements with any of their vendors as such terminations are requested by Buyer, including Fiserv Solutions, LLC.

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

(e)As of the Effective Time, all of the shares of Company Common Stock converted into the right to receive the Merger Consideration pursuant to this Section 1.4 shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, 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 Company Common Stock) previously representing any such shares of Company Common Stock shall thereafter represent only the right to receive (i) the Merger Consideration, (ii) cash in lieu of any fractional share which the holder thereof shall have become entitled to receive pursuant to Section 2.8(f) and (iii) any dividends or distributions which the holder thereof shall have become entitled to receive on the Merger Consideration pursuant to Section 2.8(c), in each case, without any interest thereon.

(f)If, prior to the Effective Time, the outstanding shares of Buyer Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split or reverse stock split, or there shall be any extraordinary dividend or distribution, and such change or event has an adverse economic effect on the value of the  Stock Consideration, then an appropriate and proportionate adjustment shall be made to the Exchange Ratio to give the holders of Company Common Stock the same economic effect as contemplated by this Agreement with respect to the Stock Consideration prior to such change or event.

(g)Notwithstanding anything in this Agreement to the contrary, any issued and outstanding shares of Company Common Stock held by a person (a “Dissenting Shareholder”) who has not voted in favor of, or consented to, the adoption of this Agreement and has complied with all the provisions of the IBCA concerning the rights of holders of shares of Company Common Stock to require payment in cash of the “fair value” of such Company Common Stock (the “Dissenting Shares”), in accordance with Sections  5/11.65 and 5/11.70 of the IBCA, as amended, shall not be converted into the right to receive the Merger Consideration and cash for fractional shares as determined in accordance with this Agreement, but shall become the right to receive such consideration as may be determined to be due to such Dissenting Shareholder pursuant to the procedures set forth in Sections 5/11.65 and 5/11.70 of the IBCA, as amended.  If such Dissenting Shareholder fails to perfect or otherwise loses its rights as a Dissenting Shareholder, in any case under the IBCA, each of such Dissenting Shareholder’s shares of Company Common Stock shall thereupon be treated as though such shares of Company Common Stock had been converted into the right to receive the Merger Consideration pursuant

​

to this Agreement. Company shall notify Buyer of each shareholder who asserts rights as a Dissenting Shareholder following receipt of such Dissenting Shareholder’s written demand delivered as provided in Section 5/11.70 of the IBCA, as amended.  Prior to the Closing Date, Company shall not, except with the prior written consent of Buyer, voluntarily make any payment, settle or commit to settle, or offer to settle any rights of a Dissenting Shareholder asserted under Section 5/11.65 of the IBCA, as amended.

(a)At the Effective Time, Company’s First Illinois Corporation 2011 Stock Compensation Plan and the First Illinois Corporation 2022 Stock Compensation Plan (collectively, the “Company Equity Plan”) and all related award agreements thereunder shall terminate and any other plan, program or arrangement of Company providing for the issuance, award or grant of any interest in respect of the capital stock of Company shall be of no further force or effect.

(b)Subject to the terms and conditions of this Agreement, at the Effective Time each option granted by Company to purchase shares of Company Common Stock under the Company Equity Plan that is outstanding as of immediately prior to the Effective Time (a “Company Stock Option”) and as set forth on Section 1.5 of the Company Disclosure Schedule shall be canceled in exchange for a cash payment, without interest, equal to the product of (i)(A) the excess, if any, of the Cash Consideration over (B) the exercise price per share of Company Common Stock under such Company Stock Option, multiplied by (ii) the number of shares of Company Common Stock covered by such Company Stock Option (each, an “Option Payment”). Each Option Payment shall be treated as compensation and shall be payable in accordance with Section 1.4(b). Each Option Payment shall be payable on or as soon as administratively practicable following the Effective Time, net of any applicable withholding taxes.

(c)Each restricted stock award in respect to a share of Company Common Stock subject to vesting, repurchase or other time-based lapse restrictions under the Company Equity Plan that is outstanding and unvested immediately prior to the Effective Time (a “Company RSA”) shall, subject to the terms and conditions of this Agreement, at the Effective Time automatically vest in full, and the shares of Company Common Stock underlying such Company RSA shall be considered outstanding shares of Company Common Stock entitled to the treatment set forth in Section 1.4(b).

(d)Subject to the terms and conditions of this Agreement, at the Effective Time each outstanding stock appreciation right of the Company granted under the Company Equity Plan that is outstanding as of immediately prior to the Effective Time (each a “Company SAR”) shall be canceled in exchange for a cash payment, without interest, pursuant to the terms and conditions of the applicable Company SAR award agreement and the Company Equity Plan (each, a “SAR Payment”). Each SAR Payment shall be treated as compensation and shall be payable in accordance with Section 1.4(b). Each SAR Payment shall be payable on or as soon as administratively practicable following the Effective Time, net of any applicable withholding taxes.

​

(e)Section 1.5 of the Company Disclosure Schedule sets forth a true, correct and complete list as of the date hereof specifying all:

ARTICLE II

​
 ALLOCATION OF PER SHARE MERGER CONSIDERATION; ELECTION PROCEDURES; EXCHANGE OF SHARES OF COMPANY COMMON STOCK

​

(a)Either First Financial Bank or Buyer’s transfer agent, to be determined in the sole discretion of Buyer, shall act as exchange agent (the “Exchange Agent”) hereunder.

(b)Buyer shall deposit, or shall cause to be deposited, with the Exchange Agent for the benefit of the holders of shares of Company Common Stock, at or prior to the Effective Time, (i) certificates, or at Buyer’s option, evidence of non-certificated shares of Buyer Common Stock in book-entry form (“Book-Entry Buyer Shares”), constituting at least the amounts necessary for the aggregate Stock Consideration, (ii) immediately available funds payable in lieu of fractional shares pursuant to Section 2.8(f), and (iii) immediately available funds constituting at least the amounts necessary for the aggregate Cash Consideration, deliverable upon due surrender of the certificates representing Company Common Stock (“Certificates”) (or affidavits of loss in lieu thereof as provided in Section 2.8(h)) or shares of Company Common Stock in book-entry form (“Book-Entry Company Shares”) pursuant to the provisions of this Article ‎II (such cash, certificates for shares of Buyer Common Stock and evidence of Book-Entry Buyer Shares, together with the amount of any dividends or other distributions payable pursuant to this Article ‎II with respect thereto, the “Exchange Fund”). The Exchange Agent shall invest the cash available in the Exchange Fund as directed by Buyer; provided that such investments shall be in obligations, funds or accounts typical for (including having liquidity typical for) transactions of this nature. To the extent that there are losses with respect to such investments, or the Exchange Fund diminishes for other reasons below the level required to make prompt cash payment of the aggregate cash portion of the Exchange Fund as contemplated hereby, Buyer shall promptly

​

replace or restore the cash in the Exchange Fund lost through such investments or other events so as to ensure that the Exchange Fund is at all times maintained at a level sufficient to make such cash payments. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable pursuant to this Agreement shall be promptly returned to Buyer. The Exchange Agent shall also act as the agent for Company’s shareholders for the purpose of receiving and holding their Certificates and Book-Entry Company Shares and shall obtain no rights or interests in the shares represented thereby.

​

​

For the avoidance of doubt, in the circumstances in which this Section 2.6 is applicable, each record holder of Cash Election Shares shall, to the extent reasonably possible, receive the same proportion of Cash Consideration, and the same proportion of Stock Consideration, with respect to their aggregate Cash Election Shares as each other record holder of Cash Election Shares receives in respect of their aggregate Cash Election Shares pursuant to this Section 2.6, subject to adjustment for fractional shares of Buyer Common Stock pursuant to Section 2.8(f).

​

For the avoidance of doubt, in the circumstances where this Section 2.7 is applicable, each record holder of Stock Election Shares shall, to the extent reasonably possible, receive the same proportion of Stock Consideration, and the same proportion of Cash Consideration, with respect to their aggregate Stock Election Shares as each other record holder of Stock Election Shares receives in respect of their aggregate Stock Election Shares pursuant to this Section 2.7, subject to adjustment for fractional shares of Buyer Common Stock pursuant to Section 2.8(f).

​

​

(a)As soon as reasonably practicable after the Effective Time (and in any event within twenty (20) days thereafter), the Exchange Agent shall mail to each holder of an Old Certificate (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to each Old Certificate shall pass, only upon delivery of such Old Certificate (or an affidavit of loss in lieu of such Old Certificate) to the Exchange Agent and shall be substantially in such form and have such other provisions as shall be prescribed by the Exchange Agent (the “Letter of Transmittal”) and (ii) instructions for use in surrendering each Old Certificate in exchange for the Merger Consideration, any cash in lieu of a fractional share of Buyer Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to Section 2.8(c). Buyer and the Exchange Agent shall be entitled to rely upon Company’s stock transfer books to establish the identity of those Persons entitled to receive the Merger Consideration, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Old Certificate, Buyer and the Exchange Agent shall be entitled to deposit any Merger Consideration, cash in lieu of any fractional share, and any dividends or distributions which the holder thereof shall have become entitled to receive on the Merger Consideration pursuant to Article II, in each case, without any interest thereon, represented thereby in escrow with an independent third party selected by Buyer and thereafter the Exchange Agent and Buyer shall each be relieved from any and all liability with respect to any claims thereto.

​

(b)As soon as reasonably practicable after surrender to the Exchange Agent of its Old Certificate or Old Certificates, accompanied by a properly completed Letter of Transmittal, such holder of Company Common Stock will be entitled to receive the Merger Consideration, any cash in lieu of a fractional share of Buyer Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such holder is entitled pursuant to Section 2.8(c), in respect of the shares of Company Common Stock represented by such holder’s Old Certificate or Old Certificates.  Until so surrendered, each Old Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration and any cash in lieu of a fractional share of Buyer Common Stock to be issued or paid in consideration therefor upon surrender of such Old Certificate in accordance with, and any dividends or distributions to which such holder is entitled pursuant to Section 2.8(c).

​

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

​

after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the Buyer Common Stock issuable with respect to such Old Certificate.

​

(d)If any certificates (including by book entry ownership) evidencing Buyer Common Stock are to be issued in a name other than that in which the Old Certificate evidencing Company Common Stock surrendered in exchange is registered, it shall be a condition of issuance that the Old Certificate so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the person requesting the exchange pay to the Exchange Agent or Buyer, as applicable, any transfer, recordation or similar Tax required by the issuance of a certificate for shares of Buyer Common Stock in any name other than that of the registered holder of the Old Certificate surrendered or otherwise demonstrate to the satisfaction of the Exchange Agent or Buyer, as applicable, that any such Tax has been paid or is not payable.

​

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

​

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

​

(g)Until the twelve (12) month anniversary of the Effective Time, Buyer shall make available on a timely basis or cause to be made available to the Exchange Agent the following: (i) certificates, or at Buyer’s option, evidence of shares in book-entry form, representing the shares of Buyer Common Stock, sufficient to pay the aggregate Merger Consideration required pursuant to Article I, and (ii) the estimated amount of cash to be paid in lieu of fractional shares of Buyer Common Stock, each to be given to the holders of Company Common Stock in exchange for Old Certificates pursuant to Article I. Upon such twelve (12) month anniversary, any such cash or certificates remaining in the possession of the Exchange Agent, together with any earnings in respect thereof, shall be delivered to Buyer.  Any holder of Old Certificates who has not exchanged his or her Old Certificates for the Merger Consideration pursuant to Article I, and

​

who has not submitted a letter of transmittal, if required, shall thereafter be entitled to look only to Buyer with respect to the Merger Consideration, any cash in lieu of any fractional share interest and any unpaid dividends and distributions on the Buyer Common Stock deliverable in respect of the shares represented by an Old Certificate such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon.  Notwithstanding the foregoing, none of Buyer, Company, the Exchange Agent or any other person shall be liable to any former holder of shares of Company Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

​

(h)If any Old Certificate shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact (an “Affidavit of Lost Certificate”) by the Person claiming such Old Certificate to be lost, stolen, or destroyed and, if required by Buyer the posting by such Person of a bond or other indemnity satisfactory to Buyer as indemnity against any claim that may be made against it with respect to such Old Certificate (an “Indemnity Bond”), the Exchange Agent will issue in exchange for such Affidavit of Lost Certificate, the Merger Consideration deliverable in respect thereof pursuant to, and in accordance with, the other terms and conditions of this Article II.

ARTICLE III
REPRESENTATIONS AND WARRANTIES OF COMPANY Except as disclosed in the disclosure schedule delivered by Company to Buyer prior to the execution and delivery of this Agreement (the “Company Disclosure Schedule”), provided, that (a) the mere inclusion of an item in the Company Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by Company that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect (as defined in Section 3.1(a)) and (b) any disclosures made with respect to a section of Article III shall be deemed to qualify (1) any other section of Article III specifically referenced or cross-referenced and (2) other sections of Article III to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure applies to such other sections, Company hereby makes the following representations and warranties to Buyer, subject to the standards contained in the next sentence. No representation or warranty of Company contained in this Article III (other than the representations and warranties in (i) Sections 3.2 and 3.8, which shall be true and correct in all respects (except in the case of Section 3.2(a) for inaccuracies that are de minimis in amount) and (ii) Sections 3.1(b) (last sentence only), 3.3, 3.7 and 3.13, which shall be true and correct in all material respects) shall be deemed untrue or incorrect, and Company shall not be deemed to have breached any of its representations or warranties, as a consequence of the existence or absence of any fact, circumstance or event unless such fact, circumstance or event, individually or taken together in the aggregate with all other facts, circumstances or events inconsistent with Company’s representations or warranties contained in this Article III, has had or is reasonably likely to have a Material Adverse Effect (disregarding for such purposes and determination any materiality, Material Adverse Effect or knowledge qualification or exception contained in any representation or warranty) on Company (the “Company Warranty Standard”).

​

​

(a)Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Illinois, and is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”).  Company has the corporate power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted.  Company is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Company.  As used in this Agreement, the term “Material Adverse Effect” means, with respect to a Party, a material adverse effect on (i) the business, properties, results of operations or financial condition of such Party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in United States generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, (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 (as hereinafter defined), (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally, (D) public disclosure of the transactions contemplated hereby or actions or inactions expressly permitted by this Agreement (including any effect on a Party’s relationships with its customers, vendors or employees) or that are taken with the prior written consent of the other Party in contemplation of the transactions contemplated hereby, (E) a decline in the trading price of a Party’s common stock or the failure, in and of itself, to meet earnings projections, but not, in either case, including the underlying causes thereof; (F)  the effects of the expenses incurred by Company or Buyer in negotiating, documenting, effecting, and consummating the transactions contemplated hereby or (G) changes, after the date hereof, resulting from hurricanes, earthquakes, tornados, floods or other natural disasters or from any outbreak of any disease or other public health events; except, with respect to subclauses (A), (B), or (C), 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 or its bank Subsidiary to timely consummate the transactions contemplated hereby.  As used in this Agreement, the word “Subsidiary” when used with respect to a Party, means any corporation, partnership, limited liability company, bank or other organization, whether incorporated or unincorporated, which is consolidated with such Party for financial reporting purposes.  True and complete copies of the articles of incorporation of Company (the “Company Articles”) and the bylaws of Company (the “Company Bylaws”), each as in effect as of the date of this Agreement, have previously been made available by Company to Buyer.

(b)Each Subsidiary of Company (a “Company Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly qualified to do business and, where such concept is recognized under applicable law, is in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership or leasing of property or the conduct of its business requires it to be so qualified and in which the failure to be so

​

qualified would reasonably be expected to have a Material Adverse Effect on Company and (iii) has all requisite power and authority to own or lease its properties and assets and to carry on its business as now conducted.  Except as set forth in this Agreement, there are no restrictions on the ability of any Company Subsidiary to pay dividends or distributions except for statutory restrictions on dividends or distributions generally applicable to all entities of the same type and, in the case of a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all such regulated entities.  The deposit accounts of Company Bank are insured by the Federal Deposit Insurance Corporation (“FDIC”) through the Deposit Insurance Fund to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened.  Section 3.1(b) of the Company Disclosure Schedule sets forth a true and complete list of all Subsidiaries of Company as of the date hereof.  Except as set forth in Section 3.1(b) of the Company Disclosure Schedule, neither Company nor any of its Subsidiaries owns any equity or profit-and-loss interest in any business enterprise, corporation, partnership or joint venture, limited liability company, association, joint-stock company, business trust or unincorporated organization, other than a Subsidiary, readily marketable securities, securities held-to-maturity in its investment portfolio, and Federal Home Loan Bank of Chicago (the “FHLB”) and Federal Reserve Bank stock.

(a)The authorized capital stock of Company consists of Seven Million Five Hundred Thousand (7,500,000) shares of Company Common Stock. As of the date of this Agreement, there are Two Million Four Hundred Twenty-Four Thousand Five Hundred and Ninety (2,424,590) shares of Company Common Stock issued and outstanding, inclusive of Five Thousand Six Hundred and Twenty-Nine (5,629) shares subject to Company RSAs. Additionally, as of the date of this Agreement, there are One Hundred Sixty-Six Thousand Eight Hundred and Forty (166,840) Company Stock Options and One Hundred Eighty Thousand One Hundred (180,100) Company SARs issued and outstanding. There are no other shares of capital stock or other voting securities of Company issued, reserved for issuance or outstanding.  All of the issued and outstanding shares of Company Common Stock have been duly authorized and validly issued and are fully paid, nonassessable and free of preemptive rights, with no personal liability attaching to the ownership thereof.  As of the date of this Agreement, there are no (A) outstanding bonds, debentures, notes or other indebtedness that have the right to vote on any matters on which shareholders of Company may vote or (B) trust preferred or subordinated debt securities of Company or any of its Subsidiaries or affiliates are issued or outstanding.  Other than the Company Stock Options, Company RSAs and Company SARs granted prior to the date of this Agreement as of the date hereof, there are no outstanding subscriptions, options, warrants, puts, calls, rights, exchangeable or convertible securities or other commitments or agreements obligating Company to issue, transfer, sell, purchase, redeem or otherwise acquire, any such securities.  There are no voting trusts, shareholder agreements, proxies or other agreements in effect with respect to the voting or transfer of Company Common Stock to which Company is a party.

​

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

​

(a)Upon reasonable notice and subject to applicable law and regulation, each of Buyer and Company, for the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, shall, and shall cause each of their respective Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors and other representatives of the other Party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments, personnel, information technology systems, and records, and each shall cooperate with the other Party in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally, and, during such period, each of Buyer and Company shall, and shall cause its respective Subsidiaries to, make available to the other Party, to the extent permissible under applicable law, (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws which is generally not available on the SEC’s EDGAR internet database, and (ii) all other information concerning its business, properties and personnel as such Party may reasonably request.  Neither Buyer nor

​

Company 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 Buyer’s or Company’s, as the case may be, customers, jeopardize the attorney-client privilege of the Party in possession or control of such information, is otherwise related to discussions of this Agreement and/or the transactions contemplated hereby, 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 will use commercially reasonable efforts to make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

In the event any subsurface or phase II site assessments are conducted (which assessments shall be at Buyer’s sole expense), Buyer shall indemnify Company and its Subsidiaries for all costs and expenses associated with returning the property to its previous condition immediately prior to conduction of any subsurface or phase II site assessment on behalf of Buyer.

​

(e)All information and materials provided pursuant to this Agreement shall be subject to the provisions of the Confidentiality Agreement entered into between the Parties as of March 16, 2026 (the “Confidentiality Agreement”).

​

​

(b)Prior to the Effective Time, Buyer shall cause the shares of Buyer Common Stock to be issued to the holders of Company Common Stock in the Merger to be authorized for listing on the Nasdaq, subject to official notice of issuance.

​

(a)Following the Effective Time, Buyer shall maintain or cause to be maintained employee benefit plans and compensation opportunities for the benefit of employees (as a group)

​

who are full-time active employees of Company and its Subsidiaries on the Closing Date  and who are retained by Buyer or any of its Subsidiaries immediately following the Effective Time (“Covered Employees”) that provide employee benefits and compensation opportunities which, in the aggregate, are substantially comparable (and equivalent) to the employee benefits and compensation opportunities that are made available on a uniform and non-discriminatory basis to similarly situated employees of Buyer or its Subsidiaries (other than Company and its Subsidiaries), as applicable; provided that (i) in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of Buyer or its Subsidiaries; and (ii) until such time as Buyer shall cause Covered Employees to participate in the benefit plans and compensation opportunities that are made available to similarly situated employees of Buyer or its Subsidiaries (other than Company and its Subsidiaries), a Covered Employee’s continued participation in employee benefit plans and compensation opportunities of Company and its Subsidiaries shall be deemed to satisfy the foregoing provisions of this sentence (it being understood that participation in the Buyer Benefit Plans may commence at different times with respect to each Buyer Benefit Plan).

​

(b)To the extent that a Covered Employee becomes eligible to participate in a Buyer Benefit Plan, Buyer shall cause such Buyer Benefit Plan to (i) recognize full-time years of prior service from the date of most recent hire of such Covered Employee with Company or its Subsidiaries for purposes of eligibility, participation and vesting, but not benefit accruals; and (ii) with respect to any Buyer Benefit Plan that is a health, dental, vision plan or other welfare plan in which any Covered Employee is eligible to participate for the plan year in which such Covered Employee is first eligible to participate, Buyer or its applicable Subsidiary shall use its commercially reasonable best efforts to cause any pre-existing condition limitations or eligibility waiting periods under such Buyer or Subsidiary plan to be waived with respect to such Covered Employee to the extent such condition was or would have been covered under the Company Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time. Notwithstanding anything to the contrary herein, each Covered Employee shall be eligible to participate in any employee stock ownership plan of the Buyer or its applicable Affiliate (“Buyer ESOP”), effective as of the Closing Date. Buyer will cause such Buyer ESOP to recognize full-time years of prior service from the date of most recent hire of such Covered Employee with Company or its Subsidiaries for all purposes, including, but not limited to, eligibility, participation and vesting.

​

(c)Prior to the Effective Time, Company shall take, and shall cause its Subsidiaries to take, all actions requested by Buyer (provided the request is made at least thirty (30) days prior to the Effective Time) that may be necessary or appropriate to (i) cause one or more Company Benefits Plans to terminate as of the Effective Time, or as of the date immediately preceding the Effective Time, (ii) cause benefit accruals and entitlements under any Company Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any Company Benefit Plan for such period as may be requested by Buyer, or (iv) facilitate the merger of any Company Benefit Plan into any employee benefit plan maintained by Buyer or a Buyer Subsidiary. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this Section

​

6.5(c) shall be subject to Buyer’s reasonable prior review and approval, which shall not be unreasonably withheld.

​

(d)The agreements set forth on Section 6.5(d)(i) of the Company Disclosure Schedule provide for payments in connection with a termination in connection with a change in control pursuant to their terms (“Change in Control Payments”). Prior to the Closing, Buyer, First Financial Bank, Company and Company Bank shall enter into a Settlement and Release Agreement with each of the individuals set forth on Section 6.5(d)(ii) of the Company Disclosure Schedule, in a form to be mutually agreed upon by Company, Buyer and the relevant individual, providing for the payment of such individual’s Change in Control Payment at or as soon as administratively reasonable following Closing.

​

(e)Buyer agrees to pay, or shall instruct its applicable Subsidiary to pay, to each Company or Company Subsidiary employee that is not covered by a written severance agreement and is terminated by Buyer or any of its Subsidiaries, without cause, within six (6) months following the Effective Time, or who is not offered a comparable position with Buyer within Twenty Five (25) miles of such employee’s existing work location and terminates employment prior to the Effective Time, a severance payment equal to two (2) weeks of his or her then current base salary multiplied by the number of total completed years of service with Company or a Company Subsidiary (without duplication) from the date of last hire; provided, however, that the minimum severance payment shall equal not less than four (4) weeks of his or her base salary and the maximum severance payment shall not exceed twenty-six (26) weeks of his or her base salary; and provided further, that such employee enters into a release of claims in a form reasonably satisfactory to Buyer.

​

(f) Nothing in this Section 6.5 shall be construed to limit the right of Buyer or any of its Subsidiaries (including, following the Closing Date, any Company Subsidiary) to amend or terminate any Company Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, nor shall anything in this Section 6.5 be construed to require Buyer or any of its Subsidiaries (including, following the Closing Date, any Company Subsidiary) to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date.

​

(g)Unless paid by Company prior to Closing, Buyer will pay discretionary bonuses to Company Bank employees earned during 2026 consistent with Company Bank past practices.

​

(a)Buyer shall purchase officers’ and directors’ liability insurance tail coverage covering the persons who are presently covered by Company’s current officers’ and directors’ liability insurance policy with respect to actions, omissions, events, matters or circumstances occurring prior to the Effective Time for a period of up to six (6) years following the Effective Time, on terms which are at least substantially equivalent to the terms of said current policy, provided that it shall not be required to expend more than an amount equal to Two Hundred Percent (200%) of the annual premium most recently paid by Company (the “Insurance Amount”) to maintain or procure officers’ and directors’ liability insurance coverage, and further provided that if Buyer is unable to maintain or obtain the insurance called for by this Section 6.6(a), Buyer

​

shall use commercially reasonable best efforts to obtain as much comparable insurance as is available for the Insurance Amount. Buyer shall cause such policy to be maintained in full force and effect, for its full term, and shall cause all obligations thereunder to be honored by the Surviving Company and no other party shall have any further obligation to purchase or pay for insurance hereunder.  The officers and directors of Company or its Subsidiaries may be required to make application and provide customary representations and warranties to Buyer’s insurance carrier for the purpose of obtaining such insurance.

​

(b)For a period of six (6) years following the Effective Time, Buyer shall indemnify and hold harmless each person who is now, or who has been at any time before the date of this Agreement, or who becomes before the Effective Time, a director or officer of Company (each, a “Company Indemnified Party”) against all losses, claims, damages, costs, expenses (including reasonable attorneys’ fees), liabilities or judgments or amounts that are paid in settlement (which settlement shall require the prior written consent of Buyer, which consent shall not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding, investigation or other legal proceeding, whether civil, criminal, administrative or investigative or investigation (each, a “Claim”), in which a Company Indemnified Party is, or is threatened to be made, a party or witness or arising out of the fact that such person is or was a director or officer of Company if such Claim pertains to any matter of fact arising, existing or occurring at or before the Effective Time (including the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the fullest extent permitted under the Company Articles or Company Bylaws to the extent permitted by applicable law including 12 USC 1828(k) and the regulations thereunder and Regulatory Agencies.

​

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

​

(d)This Section 6.6 shall survive the Effective Time, is intended to benefit each Company Indemnified Party (each of whom shall be entitled to enforce this Section against Buyer), and shall be binding on all successors and assigns of Buyer.

​

(e)In the event Buyer or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving company or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to

​

one or more other persons, then, and in each such case, proper provision shall be made so that the successors and assigns of Buyer assume the obligations set forth in this Section 6.6.

​

(a)Company agrees that, except as expressly permitted by Section 6.8(b), from the date of this Agreement until the Effective Time or, if earlier, the termination of this Agreement in accordance with Section 8.1, it will not, and will cause its Subsidiaries and its Subsidiaries’ officers, directors, and employees (the “Company Individuals”) not to, and will use its commercially reasonable efforts to cause Company and its Subsidiaries’ agents, advisors and controlled affiliates, accountants, legal counsel, and financial advisors (the “Company Representatives”) not to, initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, or engage in any discussions or negotiations concerning, or provide any confidential or nonpublic information or data concerning its and/or its Subsidiaries business, properties or assets (“Company Confidential Information”) to, or have any discussions with, any person relating to, any Acquisition Proposal (as defined below). Company will immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any persons other than Buyer with respect to any Acquisition Proposal and will use its commercially reasonable best efforts, subject to applicable law, to enforce any confidentiality or similar agreement relating to such an Acquisition Proposal.

​

(b)Notwithstanding anything to the contrary in Section 6.8(a), at any time from the date of this Agreement and prior to the Company Shareholder Meeting, in the event Company receives an unsolicited Acquisition Proposal and the Board of Directors of Company determines in good faith that such Acquisition Proposal constitutes a Superior Proposal (as defined below) or is reasonably likely to result in a Superior Proposal, Company may, and may permit its Subsidiaries and the Company Individuals and the Company Representatives to, (i) contact the person or group of persons making such Acquisition Proposal solely to clarify the terms and conditions thereof so as to determine, or assist the Board of Directors of Company in determining, whether such Acquisition Proposal constitutes, or would be reasonably expected to lead to, a Superior Proposal, (ii) use commercially reasonable efforts to negotiate the terms of, and enter into, a confidentiality agreement with terms and conditions no less favorable to Company than the Confidentiality Agreement (an “Acceptable Confidentiality Agreement”), (iii) furnish or cause to be furnished Company Confidential Information to the person making such Acquisition Proposal pursuant to an Acceptable Confidentiality Agreement, and (iv) negotiate and participate in such negotiations or discussions with the person making such Acquisition Proposal concerning such Acquisition Proposal, if the Board of Directors of Company determines in good faith (following consultation with counsel) that failure to take such actions would reasonably be likely to result in a violation of its fiduciary duties under applicable law.

​

(c)The Board of Directors of Company shall not (nor shall any committee thereof) withdraw or modify, in a manner adverse to Buyer, the Company Board Recommendation or make or cause to be made any third party or public communication proposing or announcing an intention to withdraw or modify in any manner adverse to Buyer, or fail to maintain or at the request of Buyer to reaffirm (including at the Company Shareholder Meeting), the Company Board Recommendation (any such action, a “Company Change in Recommendation”). Notwithstanding the foregoing, the Board of Directors of Company (including any committee

​

thereof) may, at any time prior to the Company Shareholder Meeting, effect a Company Change in Recommendation in response to a bona fide written unsolicited Acquisition Proposal made after the date of this Agreement that the Board of Directors of Company determines in good faith (after consultation with Company’s outside legal counsel and its financial advisor) constitutes a Superior Proposal; provided, however, that the Board of Directors of Company may not make a Company Change in Recommendation, or terminate this Agreement pursuant to Section 8.1(f), with respect to an Acquisition Proposal until it has given Buyer at least four (4) business days, following Buyer’s initial receipt of written notice that the Board of Directors of Company has determined that such Acquisition Proposal is a Superior Proposal and the reasons therefor, to respond to any such Acquisition Proposal and, taking into account any amendment or modification to this Agreement proposed by Buyer, the Board of Directors of Company determines in good faith (after consultation with counsel) that such Acquisition Proposal continues to constitute a Superior Proposal.

​

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

​

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

​

“Acquisition Proposal” means a tender or exchange offer, proposal for a merger, consolidation or other business combination involving Company or Company Bank or any proposal or offer to acquire in any manner more than 20% of the voting power in, or more than 20% of the fair market value of the business, assets or deposits of, Company or Company Bank, other than the transactions contemplated by this Agreement.

“Superior Proposal” means a bona fide written Acquisition Proposal that the Board of Directors of Company concludes in good faith to be materially more favorable from a financial point of view to its shareholders than the Merger, (i) after receiving the advice of its financial advisors; (ii) after taking into account the likelihood of consummation of such transaction on the terms set forth therein; and (iii) after taking into account all legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory and other aspects of such proposal and any other relevant factors permitted under applicable law; provided, however, that for purposes of the definition of “Superior Proposal,” the references to “more than 20%” in the definition of Acquisition Proposal shall be deemed to be references to “a majority”.

​

(a)Subject to applicable law and regulation, during the period from the date hereof until the Effective Time, Company shall cause the Chief Executive Officer and Chief Financial Officer of Company Bank to assist and confer with the officers of First Financial Bank, on a weekly basis, relating to the development, coordination and implementation of the post-Merger operating and integration plans of First Financial Bank, as the Surviving Bank in the Bank Merger.

First Financial Corporation

One First Financial Plaza

Terre Haute, Indiana 47807

​

Attention: Norman D. Lowery, Chief Executive Officer

Dear Ladies and Gentlemen:

Each of the undersigned (each, a “Shareholder”) owns shares, either of record or beneficially, of the common stock of First Illinois Corporation, Decatur, Illinois (the “Company”). Each Shareholder understands that First Financial Corporation, Terre Haute, Indiana (“you” or “FFC”), and the Company are simultaneously herewith entering into an Agreement and Plan of Merger (the “Merger Agreement”), dated as of even date herewith, providing for, among other things, the merger of the Company with and into FFC (the “Merger”), in which the outstanding shares of common stock of the Company will be exchanged for FFC common stock or cash, all as set forth in the Merger Agreement.

FFC and the Company are unwilling to expend the substantial time, effort and expense necessary to implement the Merger, including applying for and obtaining necessary approvals of regulatory authorities, unless the undersigned Shareholders enter into this Voting Agreement. Each Shareholder is entering into this Voting Agreement to induce FFC to simultaneously enter into the Merger Agreement and to consummate the Merger.

Each Shareholder confirms his agreement, severally and not jointly, with FFC as follows:

1.This Voting Agreement shall not apply to those shares of the Company common stock, if any (the “Excluded Shares”), that the Shareholder (i) may exercise voting or investment power as a fiduciary for others or (ii) as to which the Shareholder does not have, directly or indirectly, sole voting power. The Shareholder represents and warrants that the Shareholder is the record or beneficial owner of that number of shares of common stock, excluding Excluded Shares, of the Company which is set forth opposite the Shareholder’s signature on this Voting Agreement (the “Shares”).

2.The Shareholder agrees that he will not, and will not permit any company, trust or other entity controlled by the Shareholder to, contract to sell, sell or otherwise transfer or dispose of any of the Shares, other than pursuant to (i) a transfer where the transferee has agreed in writing to abide by the terms of this Voting Agreement in a form reasonably satisfactory to FFC, (ii) a transfer by will or operation of law, (iii) a transfer for estate and tax planning purposes, subject in each case to the transferee agreeing in writing to abide by the terms of this Voting Agreement, (iv) a transfer to satisfy any tax liability incurred by the Shareholder in respect of vesting, exercise or settlement of Company equity awards held by the Shareholder, where the transferee has agreed in writing to abide by the terms of this Voting Agreement in a form

​

​

reasonably satisfactory to FFC or (v) a transfer made with the prior written consent of FFC (which consent shall not be unreasonably withheld, delayed or conditioned).

3.Except as provided in Section 2 of this Voting Agreement, the Shareholder agrees to vote (or cause to be voted) all of his Shares in favor of the Merger Agreement at any meeting of shareholders of the Company called to consider and vote on the Merger Agreement.

4.The Shareholder represents and warrants to FFC that (i) the Shareholder has full legal capacity, power and authority to enter into and perform this Voting Agreement, and (ii) this Voting Agreement is the legal, valid and binding agreement of the Shareholder enforceable against the Shareholder in accordance with its terms, subject to bankruptcy, insolvency and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

5.This Voting Agreement shall automatically terminate upon the first to occur of (i) termination of the Merger Agreement in accordance with its terms; (ii) the approval of the transactions contemplated by the Merger Agreement by the Company’s shareholders; or (iii) mutual agreement in writing of the parties hereto providing for the termination hereof.

6.This Voting Agreement may be amended, modified or supplemented at any time by mutual agreement in writing of the parties hereto.

7.This Voting Agreement evidences the entire agreement between the parties hereto with respect to the matters provided for herein, and there are no agreements, representations or warranties with respect to the matters provided for herein other than those set forth herein.

8.The parties agree that, if any provision of this Voting Agreement shall under any circumstances be deemed invalid or inoperative, this Voting Agreement shall be construed with the invalid or inoperative provisions deleted, and the rights and obligations of the parties shall be construed and enforced accordingly.

9.This Voting Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same agreement.

10.The validity, construction, enforcement and effect of this Voting Agreement shall be governed by the laws of the State of Indiana.

11.This Voting Agreement shall inure to the benefit of, and shall be binding upon, the parties hereto and upon their respective executors, personal representatives, administrators, heirs, legatees, guardians, other legal representatives and successors. This Voting Agreement shall survive the death or incapacity of the Shareholder.

12.Nothing in this Voting Agreement shall be construed to give FFC any rights to exercise or direct the exercise of voting power as owner of the Shares or to vest in FFC 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 Voting Agreement, and FFC shall have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of the Company or to exercise any power or authority to direct the Shareholder in voting any of the Shares, except as otherwise expressly provided herein. It is the intent of the parties to this Voting Agreement that FFC, by reason of this Voting Agreement, shall not be deemed (until consummation of the Merger) to control, directly or indirectly, the Company and shall not exercise, or be deemed to exercise, directly or indirectly, a controlling influence over the management or policies of the Company.

13.The Shareholder agrees that, in the event of his breach of any of the terms of this Voting Agreement, FFC shall be entitled to such remedies and relief against the Shareholder as are available at law or in equity. The Shareholder acknowledges that there is not an adequate remedy at law to compensate FFC for a violation of this Voting Agreement, and irrevocably waives, to the extent permitted by law, any defense that he might have based on the adequacy of a remedy at law which might be asserted as a bar to specific performance, injunctive relief, or other equitable relief. The Shareholder agrees to the granting of injunctive relief, without the posting of any bond, and further agrees that if any bond shall be required, such bond shall be in a nominal amount.

14.The parties to this Voting Agreement acknowledge that the Shareholder is entering into this Voting Agreement solely in his capacity as a shareholder of the Company. No provision of this Voting Agreement shall preclude or in any way limit the Shareholder (or any representative of the Shareholder) from exercising his fiduciary duties as an officer or a member of the Board of Directors or an officer of the Company or Hickory Point Bank and Trust, Decatur, Illinois, to the extent applicable, and no acts taken in exercise of such fiduciary duties shall be deemed a breach of this Voting Agreement.

15.The Shareholder hereby authorizes the Company and FFC to publish and disclose in any announcement or disclosure required by the Securities and Exchange Commission and in the Proxy Statement for the meeting of shareholders of the Company called to consider and vote on the Merger Agreement, and for the meeting of shareholders of FFC called to consider and vote on the issuance of FFC common stock in the Merger, the Shareholder’s identity and ownership of the Shares and the nature of the Shareholder’s obligations under this Voting Agreement.

Please confirm that the foregoing correctly states the understanding between the Shareholder and FFC by signing and returning to FFC a counterpart hereof.
