AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger (this "Plan of Merger") is made as of March 22, 2019, by and between COUNTY BANK CORP., a Michigan corporation ("CBC"), and CHOICEONE FINANCIAL SERVICES, INC., a Michigan corporation ("ChoiceOne").

PRELIMINARY STATEMENT

1. The respective Boards of Directors of each of CBC and ChoiceOne have determined that it is in the best interests of their respective corporations and shareholders that CBC and ChoiceOne engage in a business combination in order to continue and advance their respective long-term business strategies and goals; and

2. The respective Boards of Directors of each of CBC and ChoiceOne have approved the merger of CBC with and into ChoiceOne (the "Merger") in accordance with the terms of this Plan of Merger, the Michigan Business Corporation Act and any rules or regulations promulgated thereunder (the "MBCA") and any other applicable Law; and

3. The CBC Board of Directors has, in light of and subject to the terms and conditions set forth in this Plan of Merger, (a) determined that the terms of this Plan of Merger are fair to and in the best interests of CBC and the CBC Shareholders, and (b) adopted this Plan of Merger, authorized the transactions contemplated by it and resolved to recommend approval by the CBC Shareholders of this Plan of Merger; and

4. The ChoiceOne Board of Directors has, in light of and subject to the terms and conditions set forth in this Plan of Merger, (a) determined that the terms of this Plan of Merger are fair to and in the best interests of ChoiceOne and the ChoiceOne Shareholders, and (b) adopted this Plan of Merger, authorized the transactions contemplated by it and resolved to recommend approval by the ChoiceOne Shareholders of (i) this Plan of Merger and (ii) an increase in the authorized shares of ChoiceOne Common Stock from 7,000,000 shares to 12,000,000 shares (the "Increase in Common Stock"); and

5. For federal income tax purposes, it is intended that the Merger will qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and this Plan of Merger is intended to be, and is adopted as, a "Plan of Reorganization" within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a) for purposes of Sections 354, 356 and 361 of the Code (and any comparable provisions of Michigan law) for federal and applicable Michigan state income tax purposes; and

6. All of the members of the ChoiceOne Board of Directors have executed and delivered to CBC a voting agreement in their capacity as ChoiceOne Shareholders, and all of the members of the CBC Board of Directors have executed and delivered to ChoiceOne a voting agreement in their capacity as CBC Shareholders.

In consideration of the representations, warranties, mutual covenants and agreements contained in this Plan of Merger, and for other good and valid consideration, the receipt and sufficiency of which are hereby acknowledged, CBC and ChoiceOne agree as follows:

ARTICLE I
THE MERGER

1.1 Merger. Subject to the terms and conditions of this Plan of Merger, at the Effective Time, CBC will be merged with and into ChoiceOne and the separate corporate existence of CBC will cease. CBC and ChoiceOne are each sometimes referred to as a "Constituent Corporation" prior to the Merger. At the Effective Time, the Constituent Corporations will become a single corporation, which corporation will be ChoiceOne (sometimes referred to as the "Surviving Corporation"). The effect of the Merger upon each of the Constituent Corporations and the Surviving Corporation will be as provided in Chapter Seven of the MBCA with respect to the merger of domestic corporations. Without limiting the generality of the foregoing, and subject to the MBCA, at the Effective Time: (a) all the rights, privileges, powers, franchises, licenses, and interests in and to every type of property (whether real, personal, or mixed) of CBC and ChoiceOne, will vest in the Surviving Corporation, (b) all choses in action of CBC and ChoiceOne will continue unaffected and uninterrupted by the Merger and will accrue to the Surviving Corporation, and (c) all assets and liabilities of CBC and ChoiceOne will become the assets and liabilities of the Surviving Corporation.

1.2 The Closing. CBC and ChoiceOne will consummate the Merger (the "Closing") (a) at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ + ▇▇▇▇ LLP, 900 Fifth Third Center, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇.▇., ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, at 10:00 a.m., local time, on a date no later than the fifth Business Day immediately following the day on which the last of the conditions to Closing contained in Article VI (other than any conditions that by their nature are to be satisfied at the Closing) is satisfied or waived in accordance with this Plan of Merger or (b) at such other place and time or on such other date as CBC and ChoiceOne may mutually determine (the date on which the Closing actually occurs is referred to as the "Closing Date").

1.3 Effective Time of Merger. On the Closing Date, CBC and ChoiceOne will each promptly execute and file a certificate of merger as required by the MBCA to effect the Merger (the "Certificate of Merger"). No party will take any action to revoke the Certificate of Merger after its filing without the written consent of the other party. The "Effective Time" of the Merger will be as of the time and date when the Merger becomes effective upon the filing of the Certificate of Merger with the Corporations, Securities & Commercial Licensing Bureau (Corporations Division) of the Michigan Department of Licensing and Regulatory Affairs or at such later time or date as the parties may mutually determine and specify in the Certificate of Merger. CBC and ChoiceOne agree that, if requested by CBC or ChoiceOne, the Effective Time will occur on either the last day of the month in which, or the first day of the month after which, the Closing occurs.

1.4 Additional Actions. At any time after the Effective Time, the Surviving Corporation may determine that deeds, assignments, or assurances or any other acts are necessary or desirable to vest, perfect, or confirm, of record or otherwise, in the Surviving Corporation its rights, title, or interest in, to, or under any of the rights, properties, or assets of CBC and ChoiceOne acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger, or to otherwise carry out the purposes of this Plan of Merger. CBC and ChoiceOne hereby grant to the Surviving Corporation an irrevocable power of attorney to execute and deliver all such deeds, assignments, and assurances and to do all acts necessary, proper, or convenient to accomplish this purpose. This irrevocable power of attorney will only be

operative following the Effective Time and at such time the officers and directors of the Surviving Corporation will be fully authorized in the name of CBC and ChoiceOne to take any and all such actions and execute all such instruments and documents contemplated by this Plan of Merger.

1.5 Surviving Corporation. At the Effective Time, the Surviving Corporation will have the following attributes until they are subsequently changed in the manner provided by Law:

1.5.1 Name. The name of the Surviving Corporation will be "ChoiceOne Financial Services, Inc."

1.5.2 Articles of Incorporation. The articles of incorporation of the Surviving Corporation will be the articles of incorporation of ChoiceOne as in effect immediately prior to the Effective Time, subject to Section 5.7.2.

1.5.3 Bylaws. The bylaws of the Surviving Corporation will be the bylaws of ChoiceOne as in effect immediately prior to the Effective Time, subject to Section 5.7.2.

1.5.4 Officers. The officers of the Surviving Corporation will be as set forth in Section 5.7.

1.5.5 Directors. The directors of the Surviving Corporation will be as set forth in Section 5.7.

1.6 Reservation of Right to Revise Structure. At ChoiceOne's or CBC's election, the Merger may alternatively be structured so that (a) CBC is merged with and into a direct or indirect wholly-owned Subsidiary of ChoiceOne or (b) any direct or indirect wholly-owned Subsidiary of ChoiceOne is merged with and into CBC; provided, however, that no such change will (i) alter or change the amount or kind of the Merger Consideration or the treatment of the holders of CBC Common Stock, (ii) prevent the parties from obtaining the opinions of counsel referred to in Section 6.2.5 and Section 6.3.5 or otherwise cause the transaction to fail to qualify for the Intended Tax Treatment, or (iii) materially impede or delay consummation of the transactions contemplated by this Plan of Merger. In the event of such an election, the parties agree to execute an appropriate amendment to this Plan of Merger (to the extent such amendment only changes the method of effecting the business combination and does not substantively affect this Plan of Merger or the rights and obligations of the parties or their respective shareholders) in order to reflect such election.

ARTICLE II
EFFECT OF MERGER ON CAPITAL STOCK

2.1 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of CBC, ChoiceOne or any other Person:

2.1.1 Cancellation of Excluded Shares. Each share of CBC Common Stock that is owned by CBC (or by any of its wholly-owned Subsidiaries) or ChoiceOne (or by any of its wholly-owned Subsidiaries) (collectively, the "Excluded Shares",

provided, however, that Excluded Shares will not include Trust Account Shares or DPC Shares) immediately before the Effective Time will automatically be canceled and cease to exist without delivery of any consideration in exchange for or in respect of any Excluded Share.

2.1.2 Conversion of Common Stock. Each share of CBC Common Stock issued and outstanding immediately prior to the Effective Time (other than the Excluded Shares) will be converted into the right to receive 2.0632 (the "Exchange Ratio") fully paid and nonassessable shares of ChoiceOne Common Stock (the "Merger Consideration"), whereupon such shares of CBC Common Stock will no longer be outstanding and all rights with respect to such shares of CBC Common Stock will cease to exist, except the right to receive the Merger Consideration, any cash in lieu of fractional shares payable pursuant to Section 2.6, and any dividends or other distributions payable pursuant to Section 2.3, upon surrender of Certificates or Book-Entry Shares, in accordance with Section 2.2. No interest will be paid or will accrue on any payment to holders of Certificates or Book-Entry Shares pursuant to the provisions of this Article II.

2.2 Surrender of Shares.

2.2.1 Exchange Agent; Exchange Fund. Prior to the Effective Time, ChoiceOne will deposit with Continental Stock Transfer & Trust Company or such other bank or trust company designated by ChoiceOne and reasonably satisfactory to CBC (the "Exchange Agent"), for the benefit of the holders of CBC Common Stock as of immediately prior to the Effective Time, whether represented by Certificates or held as Book-Entry Shares, shares of ChoiceOne Common Stock, in the aggregate amount equal to the number of shares of ChoiceOne Common Stock to which holders of CBC Common Stock are entitled based on the Exchange Ratio pursuant to Section 2.1.2. In addition, ChoiceOne will deposit with the Exchange Agent, prior to the Effective Time and as necessary from time to time after the Effective Time, cash in an amount sufficient to make payment in lieu of any fractional shares pursuant to Section 2.6 and payment of any dividends or other distributions payable pursuant to Section 2.3. All such shares of ChoiceOne Common Stock and cash deposited with the Exchange Agent pursuant to this Section 2.2.1 is referred to as the "Exchange Fund."

2.2.2 Exchange Procedure. As soon as reasonably practicable after the Effective Time, ChoiceOne will cause the Exchange Agent to mail to each holder of record of shares of CBC Common Stock (other than the Excluded Shares), as of the Effective Time, a form of letter of transmittal (which will be in customary form and will specify that delivery will be effected, and risk of loss and title to Certificates or Book-Entry Shares will pass, only upon proper delivery of such Certificates or Book-Entry Shares to the Exchange Agent upon adherence to the procedures set forth in the letter of transmittal) and instructions for use in effecting the surrender of Certificates or Book-Entry Shares in exchange for the Merger Consideration, any cash in lieu of fractional shares payable pursuant to Section 2.6 and any dividends or other distributions payable pursuant to Section 2.3.

Upon surrender of a Certificate or of Book-Entry Shares for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, each holder of a Certificate or of Book-Entry Shares will be entitled to receive in exchange therefor (a) book-entry shares representing the number of whole

shares of ChoiceOne Common Stock to which such holder is entitled pursuant to Section 2.1.2, (b) cash in lieu of any fractional shares payable pursuant to Section 2.6, and (c) any dividends or distributions payable pursuant to Section 2.3, and such Certificates and Book-Entry Shares so surrendered will be canceled.

In the event of a transfer of ownership of CBC Common Stock that is not registered in the transfer records of CBC, payment of the Merger Consideration may be made to a Person other than the Person in whose name the Certificates or Book-Entry Shares so surrendered are registered if certificates or other documentation are presented and are properly endorsed or otherwise in proper form for transfer, and the Person requesting such payment will pay any transfer or other Taxes required by reason of the transfer or establish, to the reasonable satisfaction of ChoiceOne, that such Taxes have been paid or are not applicable. Until surrendered as contemplated by this Section 2.2.2, each Certificate and Book-Entry Share will be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration, any cash in lieu of fractional shares payable pursuant to Section 2.6, and any dividends or other distributions payable pursuant to Section 2.3.

2.3 Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to ChoiceOne Common Stock with a record date on or after the Effective Time will be paid to the holder of any unsurrendered Certificate or Book-Entry Share with respect to the shares of ChoiceOne Common Stock that the holder of such unsurrendered Certificate or Book-Entry Share has the right to receive upon the surrender of such unsurrendered Certificate or Book-Entry Share, and no cash payment in lieu of fractional shares of ChoiceOne Common Stock will be paid to any such holder pursuant to Section 2.6, until the holder of such Certificate or Book-Entry Share will have surrendered such Certificate or Book-Entry Share in accordance with this Article II. Subject to escheat or other applicable Law, following the surrender of any Certificate or Book-Entry Share, there will be paid to the record holder of whole shares of ChoiceOne Common Stock issued in exchange therefor, without interest, with respect to such whole shares of ChoiceOne Common Stock (a) at the time of such surrender, the amount of dividends or other distributions with a record date and a payment date on or after the Effective Time and on or prior to the date of such surrender and the amount of any cash payable in lieu of a fractional share of ChoiceOne Common Stock to which such holder is entitled pursuant to Section 2.6 and (b) at the appropriate payment date, the amount of dividends or other distributions with a record date on or after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of ChoiceOne Common Stock.

2.4 Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to holders of Certificates or Book-Entry Shares for one year after the Effective Time will be delivered to ChoiceOne, upon demand, and any holders of Certificates or Book-Entry Shares who have not then complied with this Article II will thereafter look only to ChoiceOne for, and ChoiceOne will remain liable for, payment of their claims for the Merger Consideration, any cash in lieu of any fractional shares payable pursuant to Section 2.6, and any dividends or other distributions payable pursuant to Section 2.3, in accordance with this Article II.

2.5 No Further Ownership Rights in CBC Common Stock. The Merger Consideration, any cash in lieu of any fractional shares payable pursuant to Section 2.6, and any

dividends or other distributions payable pursuant to Section 2.3 upon the surrender of Certificates or Book-Entry Shares in accordance with the terms of this Article II will be deemed to have been in full satisfaction of all rights pertaining to the CBC Common Stock formerly represented by such Certificates or Book-Entry Shares. At the close of business on the Closing Date, the share transfer books of CBC will be closed, and there will be no further registration of transfers on the share transfer books of CBC of shares of CBC Common Stock that were outstanding immediately prior to the Effective Time. From and after the Effective Time, the holders of Certificates or Book-Entry Shares will cease to have any rights with respect to shares of CBC Common Stock, except as otherwise provided in this Plan of Merger or by applicable Law.

2.6 No Fractional Shares. No certificates or scrip representing fractional shares of ChoiceOne Common Stock will be issued upon the surrender for exchange of Certificates or Book-Entry Shares, no dividends or other distributions of ChoiceOne will be paid with respect to such fractional share interests, and such fractional share interests will not entitle the owner to vote or to have any rights of a holder of shares of ChoiceOne Common Stock. Notwithstanding any other provision of this Plan of Merger, each holder of Certificates or Book-Entry Shares who would otherwise have been entitled to receive a fraction of a share of ChoiceOne Common Stock (determined after taking into account all Certificates and Book-Entry Shares delivered by such holder) will receive, in lieu of such fraction of a share of ChoiceOne Common Stock, cash (without interest) in an amount equal to the product of (a) such fraction of a share of ChoiceOne Common Stock (rounded to the nearest one thousandth of a share) multiplied by (b) the daily volume weighted average price per share of ChoiceOne Common Stock on the OTC Pink marketplace (or such other securities market or stock exchange on which ChoiceOne Common Stock then principally trades) as reported by Bloomberg L.P. for the five (5) most recent trading days, ending on and including the Business Day immediately before the date on which the Effective Time occurs, on which shares of ChoiceOne Common Stock were actually traded.

2.7 No Liability. To the fullest extent permitted by applicable Law, none of CBC, ChoiceOne, the Surviving Corporation or the Exchange Agent will be liable to any CBC Shareholder or any other Person in respect of any cash properly delivered to a Governmental Entity pursuant to any applicable abandoned property, escheat or similar Laws. Any portion of the Exchange Fund remaining unclaimed by CBC Shareholders as of a date that is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity will, to the extent permitted by applicable Law, become the property of ChoiceOne free and clear of any claims or interest of any Person previously entitled thereto.

2.8 Lost, Stolen or Destroyed Certificates. In the event that any Certificate has been lost, stolen or destroyed, ChoiceOne or the Exchange Agent will, upon the receipt of an affidavit of that fact by the holder of such Certificate in form and substance reasonably satisfactory to ChoiceOne or the Exchange Agent, as the case may be, pay in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration, any cash in lieu of fractional shares payable pursuant to Section 2.6 and any dividends or other distributions payable pursuant to Section 2.3 payable in respect of the shares of CBC Common Stock previously evidenced by such lost, stolen or destroyed Certificate. ChoiceOne or the Exchange Agent, as the case may be, may, in its discretion and as a condition precedent to the payment of the Merger Consideration, any cash in lieu of fractional shares payable pursuant to Section 2.6 and any dividends or other

distributions payable pursuant to Section 2.3, require the owner of such lost, stolen or destroyed Certificate to deliver a bond in such reasonable and customary amount as ChoiceOne or the Exchange Agent, as the case may be, may reasonably direct as indemnity against any claim that may be made against ChoiceOne or the Exchange Agent with respect to such Certificate.

2.9 Withholding Rights. ChoiceOne will be entitled to deduct and withhold, or cause to be deducted or withheld, from the consideration otherwise payable pursuant to this Plan of Merger such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld, and if required, are timely paid over to or deposited with the relevant Governmental Entity by ChoiceOne, such withheld amounts will be treated for all purposes of this Plan of Merger as having been paid to the Person in respect of which such deduction and withholding was made by ChoiceOne.

2.10 Investment of Exchange Fund. The Exchange Agent will invest any cash included in the Exchange Fund as directed by ChoiceOne from time to time provided that no gain or loss thereon will affect the amounts payable or the timing of the amounts payable to CBC Shareholders pursuant to this Article II. The Exchange Fund will not be used for any purpose except as set forth herein. Any interest and other income resulting from such investments will be for ChoiceOne's account.

2.11 Adjustments. Notwithstanding anything to the contrary in this Article II, if, between the date of this Plan of Merger and the Effective Time, there is declared or effected a reorganization, reclassification, recapitalization, stock split (including a reverse stock split), split-up, stock dividend or stock distribution (including any dividend or distribution of securities convertible into ChoiceOne Common Stock or CBC Common Stock), combination, exchange, or readjustment of shares with respect to, or rights issued in respect of, ChoiceOne Common Stock or CBC Common Stock, the Exchange Ratio will be proportionately adjusted accordingly to provide to the holders of CBC Common Stock the same economic effect as contemplated by this Plan of Merger prior to such event. Notwithstanding any other provisions of this Section 2.11, no adjustment will be made in the event of the issuance of additional shares of ChoiceOne Common Stock pursuant to any dividend reinvestment plan or direct investment plan of ChoiceOne, pursuant to the exercise of stock options awarded under any director, employee or Affiliate stock option plans of ChoiceOne or its Subsidiaries, or upon the grant or sale of shares or rights to receive shares to or for the account of any director, employee, or Affiliate of ChoiceOne or any of its Subsidiaries pursuant to any stock option or other compensation or benefit plans of ChoiceOne, or in connection with the issuance of shares as merger consideration in a transaction where ChoiceOne is the surviving corporation (with the prior written consent of CBC under Section 5.2), or any offering or issuance of shares pursuant to which ChoiceOne receives cash or other consideration in exchange for the shares issued (with the prior written consent of CBC under Section 5.2). Nothing in this Section 2.11 will authorize any transaction that is prohibited by any other provision in this Plan of Merger.

2.12 Dissenting Shares. Notwithstanding anything to the contrary in this Plan of Merger, each share of CBC Common Stock issued and outstanding immediately prior to the Effective Time held by a CBC Shareholder who has not voted in favor of approval of this Plan of Merger or consented thereto in writing and who is entitled to demand and properly demands appraisal of such share pursuant to, and complies in all respects with, the provisions of the

MBCA with respect thereto, will not be converted into the right to receive any portion of the Merger Consideration and will be converted into the right to receive payment from the Surviving Corporation with respect thereto as provided by the MBCA, unless and until the holder of any such share will have failed to perfect or will have effectively withdrawn or lost his, her or its right to appraisal and payment under the MBCA, in which case such share will thereupon be deemed, as of the Effective Time, to have been converted into the right to receive the Merger Consideration in accordance with this Plan of Merger. Any shares of CBC Common Stock for which appraisal rights have been properly exercised, and not subsequently withdrawn, lost or not perfected, are referred to herein as "Dissenting Shares". CBC will give ChoiceOne prompt notice and a copy of any CBC Shareholder's demand for dissenters' rights and of any request to withdraw a demand for dissenters' rights. CBC and ChoiceOne will jointly direct all negotiations and proceedings with respect to such demands and requests. Except with the prior written consent of ChoiceOne or except as required by applicable Law, CBC will not make any payment with respect to any such demands or requests and will not settle (or offer to settle) any such demands, or requests or approve any withdrawal of the same.

ARTICLE III
CBC'S REPRESENTATIONS AND WARRANTIES

Except as specifically disclosed in the disclosure letter delivered by CBC to ChoiceOne prior to or concurrently with the execution of this Plan of Merger (the "CBC Disclosure Letter"), which sets forth, among other things, items the disclosure of which is necessary either in response to an express disclosure requirement contained in a provision of this Plan of Merger or as an exception to one or more representations or warranties of CBC contained in this Article III or to one or more covenants of CBC contained in Article V, CBC represents and warrants to ChoiceOne that:

3.1 Authorization, No Conflicts, Etc.

3.1.1 Authorization of Plan of Merger.

5.3.2 Notwithstanding anything to the contrary contained herein, if at any time prior to obtaining the CBC Shareholder Approval, CBC or any of its Representatives receives a bona fide written CBC Takeover Proposal from any Person or group of Persons, which CBC Takeover Proposal did not result from any breach of Section 5.3.1, then CBC and its Representatives may, if the CBC Board of Directors determines in good faith, after consultation with its independent financial advisors and outside legal counsel, that such CBC Takeover Proposal constitutes or is reasonably likely to lead to a CBC Superior Proposal (a) furnish, pursuant to an Acceptable CBC Confidentiality Agreement, information (including non-public information) with respect to CBC and its Subsidiaries to the Person or group of Persons who has made such CBC Takeover Proposal and their respective Representatives; provided that CBC will

CBC agrees that it and its Subsidiaries will not enter into any confidentiality or other agreements with any Person subsequent to the date of this Plan of Merger which prohibits CBC from providing any information to ChoiceOne in accordance with this Section 5.3.

remade after the date of this Plan of Merger) and that did not result from any breach of Section 5.3.1, make a CBC Adverse Recommendation Change or terminate this Plan of Merger pursuant to Section 7.1.9 to enter into a definitive merger agreement or other definitive purchase or acquisition agreement with respect to such CBC Takeover Proposal, if and only if, prior to taking such action, CBC has complied with its obligations under this Section 5.3 and the CBC Board of Directors has determined in good faith, after consultation with its independent financial advisors and outside legal counsel, that such CBC Takeover Proposal constitutes a CBC Superior Proposal; provided, however, that prior to taking any such action (a) CBC has given ChoiceOne at least five Business Days prior written notice of its intention to take such action (which notice will specify the material terms and conditions of any such CBC Superior Proposal, including the identity of the party making such CBC Superior Proposal) and such notice includes a copy of any proposed written transaction agreements and related documents with or from the Person or group of Persons making such CBC Superior Proposal, (b) CBC has negotiated, and has caused its Representatives to negotiate, in good faith with ChoiceOne during such five Business Day period to the extent ChoiceOne wishes to negotiate, to revise the terms of this Plan of Merger such that it would cause such CBC Superior Proposal to no longer constitute a CBC Superior Proposal and (c) following the end of such five Business Day period, the CBC Board of Directors will have considered in good faith any changes to this Plan of Merger proposed in writing by ChoiceOne, and will have determined that the CBC Superior Proposal would continue to constitute a CBC Superior Proposal if such revisions were to be given effect. In the event of any material revisions to a CBC Takeover Proposal during any such five Business Day period that could have an impact, influence or other effect on the CBC Board of Directors' decision or discussion with respect to whether such proposal is a CBC Superior Proposal, CBC will deliver a new written notice to ChoiceOne pursuant to the foregoing clause (a) and again comply with the requirements of this Section 5.3.5 with respect to such new written notice; provided, however, that references herein to the five Business Day period will be deemed to be references to a three Business Day period with respect thereto.

5.3.6 Provided that CBC and the CBC Board of Directors comply with their applicable obligations under Section 5.3.5, nothing in this Section 5.3 will prohibit the CBC Board of Directors from (a) taking and disclosing to the CBC Shareholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act (as if such provisions are applicable to CBC), (b) making any "stop-look-and-listen" communications to CBC Shareholders consistent with Section 14d-9(f) promulgated under the Exchange Act (or any similar communications to the CBC Shareholders) (as if such provisions are applicable to CBC), or (c) making any disclosure to the CBC Shareholders if the CBC Board of Directors determines in good faith, after consultation with legal counsel, that failure to take such action would be reasonably likely to be inconsistent with the CBC Board of Directors' fiduciary duties under applicable Law; provided, however, that the taking of any action pursuant to either of the preceding clauses (a) or (b) will in no way limit or modify the effect of this Plan of Merger with respect to any such action taken.

5.3.7 As used in this Plan of Merger, "CBC Takeover Proposal" will mean any inquiry, proposal or offer from any Person (other than ChoiceOne and its Subsidiaries) or "group", within the meaning of Section 13(d) of the Exchange Act, relating to, in a single transaction or series of related transactions, any (a) acquisition of assets of CBC and its Subsidiaries equal to more than 25% of CBC's consolidated assets or to which more than 25% of

CBC's net income on a consolidated basis are attributable, (b) acquisition of more than 25% of the outstanding CBC Common Stock or the capital stock of any Subsidiary of CBC, (c) tender offer or exchange offer that if consummated would result in any Person beneficially owning more than 25% of the outstanding CBC Common Stock, (d) merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving CBC or any of its Subsidiaries, or (e) any combination of the foregoing types of transactions if the sum of the percentage of consolidated assets, consolidated net income and CBC Common Stock involved is more than 25%; in each case, other than the Merger.

For purposes of the definition of "CBC Superior Proposal", the references to "25%" in the definition of CBC Takeover Proposal will be deemed to be references to "50%."

5.4.6 Provided that ChoiceOne and the ChoiceOne Board of Directors comply with their applicable obligations under Section 5.4.5, nothing in this Section 5.4 will prohibit the ChoiceOne Board of Directors from (a) taking and disclosing to the ChoiceOne Shareholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act (as if such provisions are applicable to

ChoiceOne), (b) making any "stop-look-and-listen" communications to ChoiceOne Shareholders consistent with Section 14d-9(f) promulgated under the Exchange Act (or any similar communications to the ChoiceOne Shareholders) (as if such provisions are applicable to ChoiceOne), or (c) making any disclosure to the ChoiceOne Shareholders if the ChoiceOne Board of Directors determines in good faith, after consultation with legal counsel, that failure to take such action would be reasonably likely to be inconsistent with the ChoiceOne Board of Directors' fiduciary duties under applicable Law; provided, however, that the taking of any action pursuant to either of the preceding clauses (a) or (b) will in no way limit or modify the effect of this Plan of Merger with respect to any such action taken.

5.4.7 As used in this Plan of Merger, "ChoiceOne Takeover Proposal" will mean any inquiry, proposal or offer from any Person (other than ChoiceOne and its Subsidiaries) or "group", within the meaning of Section 13(d) of the Exchange Act, relating to, in a single transaction or series of related transactions, any (a) acquisition of assets of ChoiceOne and its Subsidiaries equal to more than 25% of ChoiceOne's consolidated assets or to which more than 25% of ChoiceOne's net income on a consolidated basis are attributable, (b) acquisition of more than 25% of the outstanding ChoiceOne Common Stock or the capital stock of any Subsidiary of ChoiceOne, (c) tender offer or exchange offer that if consummated would result in any Person beneficially owning more than 25% of the outstanding ChoiceOne Common Stock, (d) merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving ChoiceOne or any of its Subsidiaries, or (e) any combination of the foregoing types of transactions if the sum of the percentage of consolidated assets, consolidated net income and ChoiceOne Common Stock involved is more than 25%; in each case, other than the Merger.

5.4.8 As used in this Plan of Merger, "ChoiceOne Superior Proposal" will mean any bona fide written ChoiceOne Takeover Proposal that the ChoiceOne Board of Directors has determined in its good faith judgment, after consultation with its independent financial advisors and outside legal counsel, is reasonably likely to be consummated in accordance with its terms and that is reasonably likely to result in the consummation of a transaction more favorable to the ChoiceOne Shareholders from a financial point of view than the Merger, taking into account (a) all legal, regulatory and financial aspects of the proposal (including availability of financing and certainty of closing) and the Person or group of Persons making the proposal; and (b) any changes to the terms of this Plan of Merger proposed by CBC in response to such proposal as contemplated by this Section 5.4.8. For purposes of the definition of "ChoiceOne Superior Proposal", the references to "25%" in the definition of ChoiceOne Takeover Proposal will be deemed to be references to "50%."

5.5 Preparation of the Joint Proxy Statement and Registration Statement; Shareholders' Meetings.

5.5.1 ChoiceOne will use Commercially Reasonable Efforts to prepare and cause to be filed with the SEC a Registration Statement on Form S-4 (the "Registration Statement"), in which a joint proxy statement to be sent to the ChoiceOne Shareholders and the CBC Shareholders relating to the ChoiceOne Shareholder Meeting and the CBC Shareholder Meeting will be included as a prospectus ("Joint Proxy Statement"), as promptly as practicable following the date of this Plan of Merger, but in any event within 75 calendar days following the date of this Plan of Merger (unless CBC and ChoiceOne agree

otherwise). ChoiceOne will use Commercially Reasonable Efforts to have the Registration Statement declared effective under the Securities Act as promptly as practicable after such filing and will use all Commercially Reasonable Efforts to keep the Registration Statement effective as long as reasonably necessary to consummate the Merger. Prior to the filing of the Registration Statement, ChoiceOne will consult with CBC with respect to such filing and will afford CBC and its Representatives opportunity to review and comment thereon, and ChoiceOne will use its Commercially Reasonable Efforts to incorporate into the Registration Statement any comments or changes reasonably suggested by CBC. Each of ChoiceOne and CBC will provide all information concerning itself and its Affiliates to the other, and provide such other assistance, as may be reasonably requested in connection with the preparation, filing and distribution of the Registration Statement and the Joint Proxy Statement. The Registration Statement and the Joint Proxy Statement will include all information reasonably requested by CBC to be included. If at any time prior to the ChoiceOne Shareholder Meeting or the CBC Shareholder Meeting, any event with respect to ChoiceOne or CBC or any of their respective officers and directors or Subsidiaries should occur which is required to be described in an amendment of, or a supplement to, the Joint Proxy Statement or the Registration Statement, ChoiceOne or CBC, as applicable, will promptly inform the other party so that such event may be so described, and such amendment or supplement will be promptly filed with the SEC and any state securities regulators, as applicable, and, as required by Law, disseminated to the ChoiceOne Shareholders and the CBC Shareholders.

5.5.2 CBC will, as soon as is reasonably practicable following the date on which the Registration Statement is declared effective or the effective date can be predicted with reasonable certainty, duly call, give proper notice of, convene and hold a special meeting of the CBC Shareholders for the purpose of seeking the CBC Shareholder Approval ("CBC Shareholder Meeting"). Subject to Section 5.3, CBC will use its Commercially Reasonable Efforts to (a) cause the Joint Proxy Statement to be mailed to the CBC Shareholders and to hold the CBC Shareholder Meeting as promptly as practicable after the Registration Statement is declared effective under the Securities Act, (b) solicit from the CBC Shareholders proxies to vote on the proposal to approve this Plan of Merger, and secure a quorum at the CBC Shareholder Meeting, and (c) solicit the CBC Shareholder Approval. CBC will, through the CBC Board of Directors, recommend to the CBC Shareholders that they vote for the CBC Shareholder Approval and will include such recommendation in the Joint Proxy Statement, except to the extent that the CBC Board of Directors will have made a CBC Adverse Recommendation Change as permitted by Section 5.3.

CBC may adjourn the CBC Shareholder Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Joint Proxy Statement is provided to the CBC Shareholders in advance of a vote on the CBC Shareholder Approval. Further, if as of the time for which the CBC Shareholder Meeting is originally scheduled (as set forth in the Joint Proxy Statement) there are insufficient CBC Shareholders represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such CBC Shareholder Meeting or there are insufficient votes to obtain the CBC Shareholder Approval, (i) at the request of ChoiceOne, CBC will adjourn the CBC Shareholder Meeting to a date no more than 10 Business Days later than the date of the initial CBC Shareholder Meeting; provided, that ChoiceOne may not request that CBC make such an adjournment more than once, and (ii) CBC may adjourn the CBC Shareholder Meeting.

5.5.3 ChoiceOne will, as soon as is reasonably practicable following the date on which the Registration Statement is declared effective or the effective date can be predicted with reasonable certainty, duly call, give proper notice of, convene and hold a special meeting of the ChoiceOne Shareholders for the purpose of seeking the ChoiceOne Shareholder Approval ("ChoiceOne Shareholder Meeting"). Subject to Section 5.4, ChoiceOne will use its Commercially Reasonable Efforts to (a) cause the Joint Proxy Statement to be mailed to the ChoiceOne Shareholders and to hold the ChoiceOne Shareholder Meeting as promptly as practicable after the Registration Statement is declared effective under the Securities Act, (b) solicit from the ChoiceOne Shareholders proxies to vote on the proposal to approve this Plan of Merger and the Increase in Common Stock, and secure a quorum at the ChoiceOne Shareholder Meeting, and (c) solicit the ChoiceOne Shareholder Approval. ChoiceOne will, through the ChoiceOne Board of Directors, recommend to the ChoiceOne Shareholders that they vote for the ChoiceOne Shareholder Approval and will include such recommendation in the Joint Proxy Statement, except to the extent that the ChoiceOne Board of Directors will have made a ChoiceOne Adverse Recommendation Change as permitted by Section 5.4.

ChoiceOne may adjourn the ChoiceOne Shareholder Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Joint Proxy Statement is provided to the ChoiceOne Shareholders in advance of a vote on the ChoiceOne Shareholder Approval. Further, if as of the time for which the ChoiceOne Shareholder Meeting is originally scheduled (as set forth in the Joint Proxy Statement) there are insufficient ChoiceOne Shareholders represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such ChoiceOne Shareholder Meeting or there are insufficient votes to obtain the ChoiceOne Shareholder Approval, (i) at the request of CBC, ChoiceOne will adjourn the ChoiceOne Shareholder Meeting to a date no more than 10 Business Days later than the date of the initial ChoiceOne Shareholder Meeting; provided, that CBC may not request that ChoiceOne make such an adjournment more than once, and (ii) ChoiceOne may adjourn the ChoiceOne Shareholder Meeting.

5.5.4 After the Joint Proxy Statement has been mailed to the CBC Shareholders and the ChoiceOne Shareholders, neither the CBC Shareholder Meeting nor the ChoiceOne Shareholder Meeting will be postponed without the prior written consent of ChoiceOne and CBC, respectively.

5.6 Regulatory Matters and Approvals.

5.6.1 Subject to the terms and conditions of this Plan of Merger, each of the parties will use all Commercially Reasonable Efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper, or advisable under applicable Laws and regulations to consummate and make effective the Merger. Subject to the terms and conditions of this Plan of Merger, the parties will use all Commercially Reasonable Efforts to obtain consents of all third parties and governmental bodies necessary or desirable for the consummation of the Merger.

5.6.2 Within 60 calendar days after the date of this Plan of Merger, ChoiceOne will prepare and file with the Federal Reserve Board and each other Governmental Entity having jurisdiction over the Merger all applications and documents required to obtain, and will use its Commercially Reasonable Efforts to obtain, upon terms and conditions reasonably

acceptable to ChoiceOne and CBC, each necessary approval of or consent to consummate the Merger. ChoiceOne will provide CBC with opportunities to review and comment upon such documents before filing and to make such revisions and amendments and file such supplements thereto as CBC may reasonably request. ChoiceOne will provide CBC with copies of all correspondence received from these agencies and all responsive correspondence sent to these agencies.

5.6.3 From the date of this Plan of Merger until the Effective Time, each of ChoiceOne and CBC will promptly notify the other party in writing of any pending or, to the Knowledge of ChoiceOne or CBC (as the case may be), threatened Action or Order by any Governmental Entity or any other Person (a) challenging or seeking material damages in connection with the Merger or the other transactions contemplated by this Plan of Merger (b) seeking to restrain or prohibit the consummation of the Merger or the other transactions contemplated by this Plan of Merger, or (c) otherwise relating to this Plan of Merger or any of the transactions contemplated by this Plan of Merger. If any Action or Order is instituted (or threatened to be instituted) challenging any of the transactions contemplated by this Plan of Merger as violative of any Law, each of ChoiceOne and CBC will, and will cause their respective Representatives to, cooperate and use their Commercially Reasonable Efforts to contest and resist, except insofar as ChoiceOne and CBC may otherwise agree, any such Action or Order, including any Action or Order that seeks a temporary restraining order or preliminary injunction that would prohibit, prevent or restrict consummation of the Merger or the other transactions contemplated by this Plan of Merger.

5.6.4 Nothing contained in this Plan of Merger will give CBC, directly or indirectly, the right to control or direct the operations of ChoiceOne or give ChoiceOne, directly or indirectly, the right to control or direct the operations of CBC prior to the Effective Time. Prior to the Effective Time, subject to Sections 5.1 and 5.2, as applicable, ChoiceOne and CBC each will exercise, consistent with the terms and conditions of this Plan of Merger, complete control and supervision over their respective business operations.

5.6.5 Each of ChoiceOne and CBC will, and will cause their respective Subsidiaries to, take all Commercially Reasonable Efforts as may be necessary or appropriate to transfer, or to allow for the Surviving Corporation to utilize after the Effective Time, or obtain, as permitted by Law, all Permits appropriate or necessary to continue the business of ChoiceOne and CBC and their respective Subsidiaries as currently conducted.

5.7 Governance Matters.

5.7.1 ChoiceOne's Board of Directors is, and the board of directors of the Surviving Corporation will be, divided into three (3) classes, as equal in number as possible, with the term of office of one class expiring each year. ChoiceOne will take all requisite action, effective as of the Effective Time, (a) to cause the size of the board of directors of the Surviving Corporation to be fourteen (14) directors, (b) to cause the members of the board of directors of the Surviving Corporation to be comprised of (i) seven (7) persons designated by CBC (the "CBC Designees"), and (ii) seven (7) persons designated by ChoiceOne (the "ChoiceOne Designees"); and (c) to cause the number of ChoiceOne Designees and CBC Designees in each of the three (3) classes of the Surviving Corporation's Board of Directors to be as equal as possible. If any such CBC Designee or ChoiceOne Designee, as applicable, is

unwilling, ineligible or otherwise not capable or qualified to act in such capacity, the current CBC Board of Directors or ChoiceOne Board of Directors, as applicable, will prior to the Effective Time, subject to the prior written consent of CBC or ChoiceOne, as applicable (which will not be unreasonably withheld, conditioned or delayed), designate another qualified person or persons to serve as a CBC Designee or ChoiceOne Designee, as applicable. Each CBC Designee and ChoiceOne Designee will serve for a term expiring at the next annual meeting of shareholders of the Surviving Corporation at which the term of the class of directors of which such CBC Designee or ChoiceOne Designee is a member expires, and, despite the expiration of his or her term, until his or her successor has been elected and qualified.

5.7.2 From the period beginning at the Effective Time and continuing until completion of the third (3^rd) annual shareholder meeting of the Surviving Corporation after the Effective Time (the "Designation Period"), the board of directors of the Surviving Corporation will nominate for election to the Board of Directors at each shareholder meeting of the Surviving Corporation the CBC Designees and the ChoiceOne Designees, or such replacement designees as selected by the remaining CBC Designees (in the case of a vacancy caused by departure of a CBC Designee) or ChoiceOne Designees (in the case of a vacancy caused by departure of a ChoiceOne Designee), as applicable. In the event of any vacancy in the board of directors of the Surviving Corporation during the Designation Period, whether caused by the death, disability, resignation, or removal of a director, such vacancy will be filled by the remaining CBC Designees (in the case of a vacancy caused by departure of a CBC Designee) or the remaining ChoiceOne Designees (in the case of a vacancy caused by departure of a ChoiceOne Designee). Prior to the Effective Time, ChoiceOne will cause its bylaws to be amended or, to the extent necessary, will use Commercially Reasonable Efforts to obtain the approval of the ChoiceOne Shareholders of an amendment of its articles of incorporation, (a) to reflect the terms of this Section 5.7.2 and to provide that such provisions may be amended during the Designation Period only by the vote of two-thirds of the total number of authorized directorships of the board of directors of the Surviving Corporation, regardless of any vacancies, and (b) to reflect that the mandatory age of retirement for directors of ChoiceOne will be 72 years.

added to the board of directors of ChoiceOne Bank, one (1) individual who is an officer of the Surviving Corporation and a director of Lakestone Bank.

5.8 Press Releases and Public Announcement. Each of CBC and ChoiceOne will not, and will cause its respective Representatives to not, issue any press release or make any public announcement relating to this Plan of Merger, the Merger or the other transactions contemplated by this Plan of Merger without the prior written approval of, in the case of CBC or its Representatives, ChoiceOne, and in the case of ChoiceOne or its Representatives, CBC. However, each of CBC and ChoiceOne may issue any such press release or make such public announcement, including with respect to actions contemplated by Sections 5.1 and 5.2, as applicable, it believes in good faith is required to be made by applicable Law or by any applicable securities exchange after consultation with outside legal counsel, in which case the disclosing party will advise and consult with the other party regarding any such press release or other announcement prior to making any such disclosure. Notwithstanding the foregoing, nothing in this Section 5.8 will be deemed to expand, modify or limit CBC's and ChoiceOne's rights and obligations set forth in Sections 5.3 and 5.4, as applicable. CBC and ChoiceOne agree to issue a joint press release initially announcing this Plan of Merger and the transactions contemplated by this Plan of Merger, including the Merger.

5.9 Access to Information.

5.9.1 Subject to applicable Law, during the period commencing on the date of this Plan of Merger and ending at the earlier of the Effective Time and the termination of this Plan of Merger in accordance with Article VII, CBC and ChoiceOne will, and will cause each of their Subsidiaries to, upon reasonable prior written notice, permit the other party and its respective Representatives to have reasonable access (including promptly and fully responding to all reasonable document or other information requests of the other party) at all reasonable times, and in a manner so as not to interfere with the normal business operations of CBC, ChoiceOne and each of their Subsidiaries, to the officers and senior management, the premises, agents, books, records, and Contracts of or pertaining to CBC and the CBC Subsidiaries or ChoiceOne and the ChoiceOne Subsidiaries as may be reasonably requested in writing; provided, however, that such access will (a) comply with all applicable Laws, (b) not result in, or reasonably be expected to result in, the waiver of the attorney-client privilege, (c) not result in, or reasonably be expected to result in, a material breach of any material Contract, and (d) not include any confidential supervisory information. No such access will affect the representations, warranties, covenants or agreements of the parties (or the remedies with respect thereto) or the conditions to the obligations of the parties under this Plan of Merger. CBC and ChoiceOne will use Commercially Reasonable Efforts to obtain from third parties any consents or waivers of any confidentiality restrictions with respect to any such information requested to be provided by it.

5.9.2 CBC will give prompt written notice to ChoiceOne of any event that would reasonably be expected to give rise to a CBC Material Adverse Effect. ChoiceOne will give prompt written notice to CBC of any event that would reasonably be expected to give rise to a ChoiceOne Material Adverse Effect. Each of CBC and ChoiceOne will give prompt written notice to the other party of any notice or other communication received by such party from any Governmental Entity or other Person in connection with the transactions contemplated by this Plan of Merger or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Plan of Merger.

The delivery of any notice pursuant to this Section 5.9.2 will not limit, expand or otherwise affect the remedies available hereunder (if any) to the party receiving such notice.

5.9.3 While this Plan of Merger is in effect, if either CBC or ChoiceOne becomes aware of any facts or the occurrence or impending occurrence of any event that (a) would cause one or more of the representations and warranties it has given in Article III or IV, respectively, subject to the exceptions contained in the CBC Disclosure Letter or the ChoiceOne Disclosure Letter, respectively, to become untrue or incomplete in any material respect; or (b) would have caused one or more of such representations and warranties to be untrue or incomplete in any material respect had such facts been Known or had such event occurred prior to the date of this Plan of Merger, then such party will immediately give written notice of such discovery or change, including a detailed description of the underlying facts or events, together with all reasonably pertinent documents, to the other party.

5.9.4 Each of CBC, on the one hand, and ChoiceOne, on the other hand, will, and will cause their respective Representatives to, hold and treat in confidence all documents and information concerning the other party and its Subsidiaries furnished to the applicable party or their respective Representatives in connection with the transactions contemplated by this Plan of Merger in accordance with the letter agreement, dated August 27, 2018, between CBC and ChoiceOne ("Confidentiality Agreement"), which will remain in full force and effect in accordance with its terms. Each of CBC, on the one hand, and ChoiceOne, on the other, will not, and will cause its respective directors, officers and employees to not, discuss or disclose any information concerning the Merger, or the negotiations or board discussions, deliberations or decisions in any way related to the Merger, other than information to the extent set forth in the Joint Proxy Statement, with any Person other than the Representatives of either party and any Governmental Entity.

5.10 Indemnification and Insurance.

5.10.1 All rights to exculpation, indemnification and advancement of expenses now existing in favor of the current or former directors, officers, employees or agents (each, together with such person's heirs, executors or administrators, an "Indemnified Party"), as the case may be, of CBC or the CBC Subsidiaries as provided in their respective articles of incorporation or bylaws or other organization documents or in the existing indemnity agreements with CBC or any of the CBC Subsidiaries will survive the Merger, be honored and assumed by the Surviving Corporation and continue in full force and effect in accordance with their terms. For a period of six years from the Effective Time, the Surviving Corporation, to the fullest extent permitted by applicable Law, will maintain in effect exculpation, indemnification and advancement of expenses provisions that are no less favorable to officers, directors, employees or agents than those set forth in the articles of incorporation and bylaws or similar organization documents of CBC and the CBC Subsidiaries in effect immediately prior to the date of this Plan of Merger, and, subject to compliance with applicable Law, will not amend, repeal or otherwise modify any such provisions in any manner that would adversely affect the rights thereunder of any individuals who at the Effective Time were current or former directors, officers, employees or agents of CBC or any of the CBC Subsidiaries. All rights to exculpation, indemnification or advancement of expenses in respect of any Action pending or asserted or any claim made within such period will continue until the disposition of such Action or resolution of such claim. In the

event of any such Action, the Surviving Corporation will use Commercially Reasonable Efforts to cooperate with the Indemnified Party in the defense of the Action.

5.10.2 CBC will purchase, prior to the Effective Time, at a cost not exceeding 300% of the last annual premium of each policy, a six-year prepaid "tail" policy on terms and conditions providing substantially equivalent benefits as the current policies of bankers' blanket bond, directors' and officers' liability insurance and fiduciary liability insurance maintained by CBC and the CBC Subsidiaries for the Indemnified Parties with respect to matters occurring at or prior to the Effective Time, including the transactions contemplated by this Plan of Merger. The Surviving Corporation will maintain such policy in full force and effect for its full term and honor all obligations thereunder.

5.10.3 The rights of each Indemnified Party hereunder will be in addition to, and not in limitation of, any other rights such person may have under the articles of incorporation or bylaws or other organization documents of CBC or any of the CBC Subsidiaries or the Surviving Corporation, any other indemnification arrangement, the MBCA, directors' and officers' insurance claims under any policy that is or has been in existence with respect to CBC or the CBC Subsidiaries or otherwise. The provisions of this Section 5.10 will survive the consummation of the Merger and expressly are intended to benefit, and are enforceable by, each of the Indemnified Parties, each of whom is a third-party beneficiary of this Section 5.10.

5.10.4 In the event that the Surviving Corporation or its successors or assigns (a) consolidates with or merges into any other person and will not be the continuing or surviving corporation or entity in such consolidation or merger or (b) transfers all or substantially all of its properties and assets to any Person, in each case, proper provision will be made so that the successors and assigns of the Surviving Corporation, as the case may be, will assume the obligations set forth in this Section 5.10.

5.11 Takeover Laws. If any Takeover Law is or may become applicable to the Merger, the parties will use their respective Commercially Reasonable Efforts to (a) take such actions as are reasonably necessary so that the transactions contemplated hereunder may be consummated as promptly as practicable on the terms contemplated by this Plan of Merger and (b) otherwise take all such actions as are reasonably necessary to eliminate or minimize the effects of any such Law on the Merger and the transactions contemplated by this Plan of Merger.

5.12 Section 16 Matters. Prior to the Effective Time, CBC and ChoiceOne each will take all such steps as may be required to cause any acquisitions or dispositions of ChoiceOne Common Stock (including derivative securities with respect to ChoiceOne Common Stock) resulting from the Merger and the other transactions contemplated by this Plan of Merger, by each individual who may become or is reasonably expected to become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to ChoiceOne immediately following the Effective Time, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

5.13 Securityholder Litigation. Each party will keep the other party reasonably informed with respect to the defense or settlement of any securityholder Action against it or its directors or officers relating to the Merger or the other transactions contemplated by this Plan of Merger. Each party will give the other party the opportunity to consult with it regarding the

defense or settlement of any such securityholder Action and will not settle any such Action without the other party's prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

5.14 Tax-Free Reorganization Treatment.

5.14.1 CBC and ChoiceOne intend that the Merger will qualify as a reorganization under Section 368(a) of the Code (the "Intended Tax Treatment"), and each will not, and will not permit any of their respective Subsidiaries to, take any action, agree to take any action, or fail to take or agree to take any action, that would reasonably be expected to jeopardize the qualification of the Merger as a reorganization under Section 368(a) of the Code. CBC and ChoiceOne intend that this Agreement constitute and hereby adopt this Agreement as a "Plan of Reorganization" within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a) for purposes of Sections 354, 356 and 361 of the Code (and any comparable provisions of Michigan law) for federal and applicable Michigan state income tax purposes and this Agreement will be interpreted consistent with that intent. CBC and ChoiceOne will use Commercially Reasonable Efforts, and will cause their respective Subsidiaries to use Commercially Reasonable Efforts, to cause the Merger to qualify as a reorganization within the meaning of Section 368(a) of the Code, including providing reasonable and customary representations, covenants and certificates requested by counsel under Sections 6.2.5 and 6.3.5. If the Merger would not qualify as a reorganization within the meaning of Section 368(a) of the Code and the Treasury Regulations thereunder, then CBC and ChoiceOne agree to reasonably adjust the terms of this Agreement as needed in order for the Merger to qualify as a reorganization within the meaning of Section 368(a) of the Code and the Treasury Regulations thereunder. Within 45 days following the Effective Time, the Surviving Corporation will comply with the reporting requirements of Section 1.6045B-1(a)(2) of the Treasury Regulations.

5.14.2 Each of CBC and ChoiceOne will report the Merger as a reorganization within the meaning of Section 368(a) of the Code on its United States federal income Tax Return, unless otherwise required pursuant to a "determination" within the meaning of Section 1313(a) of the Code.

5.15 Pre-Merger Special Dividend. The ChoiceOne Board of Directors may, subject to applicable Law and the ChoiceOne articles of incorporation and bylaws, declare a special cash dividend in an amount equal to $0.60 per share of ChoiceOne Common Stock (subject to customary adjustments for any stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or similar event following the date of this Plan of Merger) with a record date and payment date after the satisfaction of the conditions set forth in Sections 6.1, 6.2 and 6.3 (other than those conditions that by their nature are to be satisfied by actions taken at the Closing but which conditions would be satisfied (including the delivery of officers' certificates without qualifications or exceptions) if such date were the Closing Date) (any such dividend, the "Pre-Merger Special Dividend"), and set the record date and payment date for such Pre-Merger Special Dividend in its sole discretion. Notwithstanding anything in this Agreement to the contrary, the amount of the Pre-Merger Special Dividend will be adjusted if necessary to preserve the status of the Merger as a tax-free reorganization within the meaning of Section 368(a) of the Code.

5.16 Dividends. CBC and ChoiceOne will coordinate with each other regarding the declaration, setting of record dates, and payment dates of dividends with respect to shares of CBC Common Stock and ChoiceOne Common Stock for the purpose of minimizing the risk that holders of shares of CBC Common Stock (a) in respect of any calendar quarter, receive dividends on both shares of CBC Common Stock and shares of ChoiceOne Common Stock received as Merger Consideration or (b) in respect of any calendar quarter, fail to receive a dividend on shares of CBC Common Stock or shares of ChoiceOne Common Stock received as Merger Consideration.

5.17 Expenses. Whether or not the Merger is consummated, except as otherwise provided in this Plan of Merger, all costs and expenses incurred in connection with this Plan of Merger and the transactions contemplated by this Plan of Merger will be paid by the party incurring such expenses, except that CBC and ChoiceOne will each pay and bear one-half of (a) each regulatory filing, notification, registration or similar fee required to be paid by any party in connection with this Plan of Merger and the transactions contemplated by this Plan of Merger under the Securities Act, the Exchange Act, applicable banking Laws and other applicable Laws and (b) any fees and expenses (excluding each party's internal costs and fees and expenses of attorneys, accountants and financial and other advisors) incurred in respect of printing, filing and mailing of the Joint Proxy Statement and the Registration Statement.
