ARTICLE 2 — CONVERSION AND EXCHANGE OF SHARES

        2.1.           Conversion of Shares. Subject to the terms and conditions of this Plan of Merger and except as provided below, at the Effective Time, by virtue of the Merger and without any further action on the part of Acquirer, ICNB or the holders of any shares thereof, the shares of the Constituent Corporations shall be converted as follows:

        2.1.1       Each share of common stock of Acquirer (“Acquirer Common Stock”) issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding from and after the Effective Time.

        2.1.2        Subject to the potential adjustment provided for in Sections 2.2 through 2.4 below, each share of common stock of ICNB (“ICNB Common Stock”) (excluding shares held by ICNB or any of its affiliates, other than in a fiduciary capacity or as a result of debts previously contracted) issued and outstanding at the Effective Time shall cease to be outstanding and shall be converted into and exchanged for the right to receive shares of Acquirer Common Stock and/or cash as set forth in this Section 2.1 (the “Merger Consideration”).

        2.1.3        Holders of ICNB Common Stock may elect to receive shares of Acquirer Common Stock or cash in exchange for their shares of ICNB Common Stock. The total number of shares of ICNB Common Stock to be converted into Acquirer Common Stock (the “Stock Consideration”) shall equal 50% of the total outstanding shares of ICNB Common Stock, or such larger number of shares as results from rounding up fractional shares pursuant to Section 2.8.8. All shares of ICNB Common Stock not exchanged for Acquirer Common Stock shall be exchanged for $31.50 in cash per share (the “Cash Consideration”).

        2.1.4        At the election of each holder of ICNB Common Stock, each share of ICNB Common Stock held by that holder may be exchanged for 1.407 shares of Acquirer Common Stock (the “Exchange Ratio”), subject to the election restrictions set forth above and below.

3

        2.1.5       An Election Form, in such form as Acquirer and ICNB mutually agree (“Election Form”), will be included in and sent with the Prospectus and Proxy Statement, which shall be mailed to each holder of record of ICNB Common Stock entitled to vote at the ICNB Shareholders’ Meeting, permitting such holder, subject to the allocation and election procedure set forth herein:

        (a)        to specify the number of shares of ICNB Common Stock owned by such holder with respect to which the holder desires to receive Cash Consideration (a “Cash Election”) in accordance with the provisions stated herein;

        (b)        to specify the number of shares of ICNB Common Stock owned by such holder with respect to which such holder desires to receive Stock Consideration (a “Stock Election”); or

        (c)        to indicate that such record holder has no preference as to the receipt of Stock Consideration or Cash Consideration for such shares (a “Non-Election”).

                Holders of record of shares of ICNB Common Stock who hold such shares as nominees, trustees or in other representative capacities (a “Representative”) may submit multiple Election Forms, provided that each such Election Form covers all the shares of ICNB Common Stock held by each representative for a particular beneficial owner.

                Any shares of ICNB Common Stock with respect to which the holder thereof has not, as of the Election Deadline (defined below), made an election by submission to ICNB of an effective, properly completed Election Form shall be deemed Non-Election shares.

                Each holder of ICNB Common Stock will have the right to change his or her election to a Cash Election or Stock Election at any time prior to the Election Deadline (as defined in subparagraph 2.1.6 below) by submitting a new Election Form to ICNB.

        2.1.6       The term “Election Deadline” shall mean the same deadline as for the return of the proxy card relating to the shareholder vote pursuant to the proposed Merger at the ICNB Shareholders’ Meeting. An election will have been properly made only if ICNB has actually received a properly completed Election Form by the Election Deadline. Subject to the terms of this Plan of Merger and of the Election Form, Acquirer and the Exchange Agent will have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Election Forms, and any decisions of Acquirer regarding such matters shall be binding and conclusive. None of ICNB, Acquirer or the Exchange Agent shall be under any obligation to notify any person of any defect in an Election Form.

        2.1.7       As soon as practicable, but in no event more than three (3) Business Days after the Election Deadline, Acquirer and Exchange Agent shall prepare a schedule (the “Exchange Schedule”), calculating the amount of cash and Acquirer Common Stock that each ICNB shareholder will be entitled to receive, listed by ICNB stock certificate number, pursuant to the provisions of Article 2 hereof. Such Exchange Schedule shall be delivered to ICNB within one (1) business day after it has been prepared. ICNB shall have three (3) Business Days to provide Acquirer and the Exchange Agent with any objections, comments or questions concerning the Exchange Schedule.

4

        2.1.8       The “Stock Election Number” means the aggregate number of shares of ICNB Common Stock with respect to which Stock Elections have been made. The “Cash Election Number” means the aggregate number of shares of ICNB Common Stock with respect to which Cash Elections have been made.

        2.1.9       If the Stock Election Number exceeds 621,706 (50% of the total outstanding shares of ICNB Common Stock), then:

        (a)        All Non-Election shares of each holder of ICNB Common Stock shall be converted into the right to receive the Cash Consideration; and

        (b)        All Stock Election shares of each holder of ICNB Common Stock will be adjusted, on a pro-rata basis, such that the aggregate number of shares of ICNB Common Stock electing Stock Consideration equals 621,706(50% of the total outstanding shares of ICNB Common Stock), or such larger number of shares as results from rounding up fractional shares. Such adjustment (the “Adjusted Stock Election”) shall be determined as follows: the number of Adjusted Stock Election shares that each holder of ICNB Common Stock who properly elected Stock Consideration will be entitled to receive shall equal the product obtained by multiplying (x) the number of Stock Election shares held by such holder by (y) a fraction, the numerator of which is 621,706 (50% of the total outstanding shares of ICNB Common Stock) and the denominator of which is the Stock Election Number. The Adjusted Stock Election shares shall then be converted into the right to receive shares of Acquirer Common Stock determined by multiplying the number of Adjusted Stock Election shares by the Exchange Ratio, with any fractional shares being rounded up to the nearest whole number. The remaining number of such holder’s Stock Election shares shall be converted into the right to receive the Cash Consideration.

        2.1.10       If the Stock Election Number is less than 621,706 (50% of the total outstanding shares of ICNB Common Stock), then:

        (a)        All Non-Election shares of each holder of ICNB Common Stock or, if less than all, such number of Non-Election shares as necessary to reduce the aggregate number of shares of ICNB Common Stock receiving Cash Consideration to 621,706 (50% of the total outstanding shares of ICNB Common Stock) (allocated on a pro-rata basis), shall be converted into the right to receive the Stock Consideration; and

5

        (b)        To the extent that the aggregate number of shares of ICNB Common Stock that are to be allocated Stock Consideration after the conversion (noted in paragraph (a) above) of Non-Election shares still is less than 621,706 (50% of the total outstanding shares of ICNB Common Stock); then the Cash Election shares of each holder of ICNB Common Stock, will be adjusted such that the aggregate number of shares of ICNB Common Stock converting to Stock Consideration equals 621,706 (50% of the total outstanding shares of ICNB Common Stock), or such larger number of shares as results from rounding up fractional shares. Such adjustment (the “Adjusted Cash Election”) shall be determined as follows: the number of Adjusted Cash Election shares that each holder of ICNB Common Stock will be entitled to exercise shall equal the product obtained by multiplying (x) the number of Cash Election shares held by such holder by (y) a fraction, the numerator of which is 621,706 (50% of the total outstanding shares of ICNB Common Stock) and the denominator of which is the Cash Election Number. The Adjusted Cash Election shares are then converted into the right to receive Cash Consideration by multiplying the Adjusted Cash Election shares by $31.50. The remaining number of such holder’s Stock Election shares shall be converted into the right to receive the Stock Consideration.

        2.1.11       If the Stock Election Number equals 621,706(50% of the total outstanding shares of ICNB Common Stock), then all holders who have submitted a proper and timely Election Form shall be converted into the right to receive Stock Consideration and/or Cash Consideration as they have properly elected. In such event, all Non-Election Shareholders shall be converted into the right to receive the Cash Consideration only.

        2.1.12       ICNB represents that there are no outstanding options or warrants to purchase ICNB Common Stock. Any outstanding and unexercised options to purchase shares of ICNB Common Stock will be cancelled and cease to represent an option to purchase ICNB Common Stock at the Effective Time. ICNB agrees that prior to the Effective Time it will amend the ICNB Amended and Restated Deferred Compensation and Deferred Stock Purchase Plan to require that all distributions be in cash and not in the form of common stock.

        2.2.           Upset Provision. On the date of the Closing, ICNB shall have the right to terminate this Plan of Merger upon written notice to the Acquirer if the Upset Condition (defined below) then exists.

        2.2.1        The “Upset Condition” shall have occurred if both of the following conditions exist:

        (a)        The Final Acquirer Price (as defined below) is less than $18.40 (the “Floor Acquirer Price”); and

        (b)        The number determined by dividing the Final Acquirer Price by $21.65(the “Initial Acquirer Price”) is less than the number obtained by subtracting (i) 0.15 from (ii) the quotient obtained by dividing the Final Index Value (as defined below) by the Initial Index Value (as defined below) (“Index Value Ratio”).

6

        2.2.2       The “Final Acquirer Price” means the average of the closing prices per share of Acquirer Common Stock reported on the NASDAQ during the ten consecutive full trading days on which Acquirer’s stock is actually traded prior to the date of the Closing (the “Pricing Period”).

        2.2.3       The “Initial Index Value” means the closing value of the NASDAQ Bank Index (CBNK:IND), a Sector Index maintained by the NASDAQ (“Bank Index”) on January 31, 2007.

        2.2.4        The “Final Index Value” means the closing value of the Bank Index at the end of the Pricing Period.

        2.3.           Adjustment to Cure the Upset Condition. If the Upset Condition exists and ICNB provides written notice to the Acquirer of ICNB’s desire to exercise its right to terminate this Plan of Merger, Acquirer shall have the option, exercisable within five Business Days of receipt thereof, to increase the Stock Consideration to the Revised Stock Consideration. For purposes of this Agreement, the “Revised Stock Consideration” shall equal the product of the Stock Consideration multiplied by the a number (rounded to three decimals) equal to a quotient, the numerator of which is the Floor Acquirer Price multiplied by the Exchange Ratio and the denominator of which is the Final Acquirer Price. If Acquirer elects to exercise its option to increase the Stock Consideration, Acquirer shall provide prompt written notice to ICNB of such election and the amount of the Revised Stock Consideration, at which time the ICNB shall have no further right to terminate this Agreement pursuant to an Upset Condition, and this Agreement shall remain in effect in accordance with its terms (except the Stock Consideration shall have been modified as provided in this Section 2.3, and any references in this Agreement to the “Stock Consideration” shall thereafter be deemed to refer to the Revised Stock Consideration).

        2.4.           Adjustments. The Stock Consideration and Cash Consideration and the related computations described in Sections 2.1 and 2.2 shall be adjusted in the manner provided in this Section 2.4 upon the occurrence of any of the following events:

        2.4.1       Changes in Number of Outstanding Shares. If either ICNB or Acquirer changes (or establishes a record date for changing) the number of shares of Acquirer Common Stock or the number of shares of ICNB Common Stock, issued and outstanding as of the date of this Plan of Merger, as a result of a stock dividend, stock split, recapitalization or similar transaction with respect to such issued and outstanding shares, and the record date for such transaction is after the date of this Plan of Merger and prior to the Effective Time, then the Stock Consideration and the Cash Consideration shall be appropriately and proportionately adjusted as such that the actual aggregate consideration to be paid by Acquirer to holders of shares of ICNB Common Stock pursuant to Section 2.1 above would be the same as would have been paid if the Effective Time had been the close of business on the date of this Plan of Merger.

7

        2.4.2       Adjustments for the Upset Condition. If Acquirer declares a stock dividend, stock split, or other general distribution of Acquirer Common Stock to holders of Acquirer Common Stock prior to the date of the Effective Time, then the Floor Acquirer Price and the Initial Acquirer Price shall each be adjusted by multiplying them by a fraction (i) the numerator of which shall be the total number of shares of Acquirer Common Stock outstanding immediately prior to such dividend, split, or distribution; and (ii) the denominator of which shall be the total number of shares of Acquirer Common Stock that are or will be outstanding immediately after such dividend, split, or distribution. For the purposes of this Section, the number of outstanding shares shall be computed as of the record date of the distribution.

        2.4.3       Authorized Issuances. Notwithstanding any other provisions of this Section, no adjustment shall be made in the event of the issuance of additional shares of Acquirer Common Stock pursuant to the dividend reinvestment plan of Acquirer, if any, pursuant to the exercise of stock options awarded under director or employee stock option plans of Acquirer, if any, or upon the grant or sale of shares or rights to receive shares to, or for, the account of Acquirer’s directors or employees pursuant to their restricted stock, deferred stock compensation, thrift, employee stock purchase and other compensation or benefit plans of Acquirer, if any.

        2.4.4       Changes in Capital. Subject only to making any adjustment provided above in related computations prescribed in this Section, nothing contained in this Plan of Merger shall preclude Acquirer from amending its Articles of Incorporation to change its capital structure or from issuing additional shares of Acquirer Common Stock, preferred stock, shares of other capital stock or securities that are convertible into shares of capital stock.

        2.5.           Postponement of Closing. Acquirer and ICNB agree not to convene the Closing at any time that would result in there being a record date, ex-dividend date, or ex-distribution date for any transaction described in Sections 2.4.1 (Changes in Number of Outstanding Shares) at any time after the beginning of the Pricing Period.

        2.6.           Increase in Outstanding Shares of ICNB Common Stock. If the number of shares of ICNB Common Stock outstanding is greater than 1,243,412 for any reason whatsoever (whether or not such increase constitutes a breach of this Plan of Merger), then the Stock Consideration and Cash Consideration shall be adjusted by multiplying each by a fraction (a) the numerator of which shall be 1,243,412, and (b) the denominator of which shall be the total number of shares of ICNB Common Stock outstanding as of the Effective Time of the Merger.

        2.7.           Cessation of Shareholder Status. As of the Effective Time, each record holder of shares of ICNB Common Stock outstanding immediately prior to the Effective Time shall cease to be a shareholder of ICNB and shall have no rights as a shareholder of ICNB. Each stock certificate representing shares of ICNB Common Stock outstanding immediately prior to the Effective Time (“Old Certificates”) shall then be considered to represent the right to receive the Merger Consideration as provided in this Plan of Merger.

8

        2.8.           Surrender of Old Certificates and Payment of Merger Consideration. After the Effective Time, Old Certificates shall be exchangeable by holders for the Merger Consideration to which such holders shall be entitled in the following manner:

        2.8.1       Available Shares and Funds. At the Effective Time, Acquirer shall make available to Exchange Agent an amount of cash and a number of shares of Acquirer Common Stock sufficient to make payments of the Merger Consideration for each outstanding share of ICNB Common Stock.

        2.8.2       Transmittal Materials. As soon as practicable after the Effective Time, but no later than five (5) Business Days after the date of the Closing, Acquirer shall send or cause to be sent to each record holder of ICNB Common Stock as of the Effective Time transmittal materials for use in exchanging that holder’s Old Certificates and receiving the Merger Consideration.

        2.8.3       Exchange Agent. On or prior to the Effective Time, Acquirer will deliver to Registrar and Transfer Company, or such other bank or trust company as Acquirer may designate (the “Exchange Agent”), written notice of the number of shares of Acquirer Common Stock issuable in the Merger and a commitment to pay the amount of cash payable in the Merger when and as determined. Acquirer and the Exchange Agent shall have discretion to determine reasonable procedures relating to the issuance and delivery of certificates of Acquirer Common Stock and cash and governing the payment for fractional shares.

                The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to such shares of Acquirer Common Stock, except that it shall receive and hold all dividends or other distributions paid or distributed with respect to such shares for the account of the record holders entitled to such shares.

        2.8.4       New Stock Registrations. Acquirer shall cause the Exchange Agent to promptly cause to be paid to the persons entitled thereto a check in the amount of the Cash Consideration to which the persons are entitled, after giving effect to any required tax withholding, and register the shares of Acquirer Common Stock issuable to former ICNB shareholders of record in such manner, in the names and to the addresses that appear on ICNB’s stock records as of the Effective Time, or in such other name or to such other address as may be specified by the shareholder of record in transmittal documents received by the Exchange Agent; provided, that with respect to each former ICNB shareholder, the Exchange Agent shall have received all of the Old Certificates held by that shareholder, or an affidavit of loss and indemnity bond for such certificate or certificates, together with properly executed transmittal materials; and such certificates, transmittal materials, affidavits, and bonds are in a form and condition reasonably acceptable to Acquirer and the Exchange Agent.

        2.8.5       Dividends Pending Surrender. Whenever a dividend is declared by Acquirer on Acquirer Common Stock that is payable to shareholders of record of Acquirer’s Common Stock as of a record date after the Effective Time, the declaration shall include dividends on all shares issuable under this Plan of Merger. No former shareholder of ICNB shall be entitled to receive a distribution of any such dividend until the Exchange Agent has received all of that shareholders’ Old Certificates (or an affidavit of loss and indemnity bond for such certificates) pursuant to properly submitted transmittal materials. Upon the exchange of that shareholder’s Old Certificates (or an affidavit of loss and indemnity bond for such certificates), the shareholder shall be entitled to receive from Acquirer an amount equal to all such dividends (without interest thereon and less the amount of taxes, if any, that may have been imposed or paid thereon) declared and paid with respect to the shares of Acquirer Common Stock represented thereby. If such a shareholder has then elected to enroll in Acquirer’s dividend reinvestment program, such amount shall be credited as a cash purchase for investment at the plan’s next regular investment date.

9

        2.8.6       Stock Transfers. After the Effective Time, there shall be no transfers on ICNB’s transfer books of the shares of ICNB Common Stock that were issued and outstanding immediately prior the Effective Time. If, after the Effective Time, Old Certificates are properly presented for transfer, they shall be canceled and exchanged for the shares of Acquirer Common Stock as provided in this Plan of Merger. After the Effective Time, ownership of such shares as represented by any Old Certificates may be transferred only on the stock records of Acquirer.

        2.8.7       Exchange Agent Expenses. Acquirer shall pay all charges and expenses, including those of the Exchange Agent, in connection with the payment of the Merger Consideration in exchange for the ICNB Common Stock.

        2.8.8       No Fractional Shares. No certificates or scrip representing fractional shares of Acquirer Common Stock shall be issued in the Merger upon the surrender of Old Certificates. No fractional interest in any share of Acquirer Common Stock resulting from the Merger shall be entitled to any part of a dividend, distribution or stock split with respect to shares of Acquirer Common Stock nor entitle the record holder to vote or exercise any rights of a shareholder with respect to that fractional interest. In lieu of issuing any fractional share, the number of shares of Acquirer Common Stock to be issued to each holder of an Old Certificate who would otherwise have been entitled to a fractional share of Acquirer Common Stock upon surrender of all Old Certificates for exchange shall be rounded up to the nearest whole number.

11

        3.4.1       Classes and Shares. The authorized capital stock of Acquirer consists of 20,000,000 shares of common stock, no par value, and 300,000 shares of preferred stock, no par value.

12

        3.5.           Acquirer Common Stock. The shares of Acquirer Common Stock to be issued in the Merger in accordance with this Plan of Merger, when issued as contemplated by this Plan of Merger, will be validly issued, fully paid, and nonassessable shares.

No financial statements of any entity or enterprise other than the subsidiaries are required by GAAP to be included in the consolidated financial statements of Acquirer.

        3.6.2       Call Reports. The following reports (including all related schedules, notes, and exhibits) were prepared and filed in conformity with applicable regulatory requirements and were correct and complete in all material respects when filed:

All of the reports identified in this Section are collectively referred to as the “Call Reports.”

        3.7.           Absence of Undisclosed Liabilities. Except as and to the extent reflected or reserved against in Acquirer’s Financial Statements as of December 31, 2005, or September 30, 2006, neither Acquirer nor its subsidiaries had, as of such date, liabilities or obligations, secured or unsecured (whether accrued, absolute, or contingent) that, as of such date, would be reasonably likely to have a Material Adverse Effect on Acquirer.

13

        3.8.           Absence of Material Adverse Changes. Since December 31, 2005, there has been no change in the financial condition, income, expenses, assets, liabilities or business of Acquirer or any of its subsidiaries that had or in the future is reasonably likely to have a Material Adverse Effect on Acquirer, other than such changes that are caused by events and circumstances generally affecting the banking industry as a whole. No facts or circumstances have been discovered from which it reasonably appears that there is a reasonable probability that there will occur a change that could have a Material Adverse Effect on Acquirer, other than such changes that are caused by events and circumstances generally affecting the banking industry as a whole.

        3.9.           Legal Proceedings. There is no action, suit, proceeding, claim, arbitration, or investigation pending or to the knowledge of Acquirer threatened by any person, including without limitation any governmental or regulatory agency, against Acquirer or any of the subsidiaries, or the assets or business of Acquirer or any of its subsidiaries, any of which is reasonably likely to have a Material Adverse Effect on Acquirer. There is no factual basis that presents a reasonable potential for any such action, suit, proceeding, claim, arbitration, or investigation.

        3.10.           Regulatory Filings. In the last four (4) years:

        3.10.1       SEC Filings. Acquirer has filed, and will in the future continue to file, in a timely manner all material required filings with the SEC;

        3.10.2        Regulatory Filings. Acquirer has filed in a timely manner all other material filings with other regulatory bodies for which filings are required; and

        3.10.3       Complete and Accurate. All such filings, as of their respective filing dates, did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except for any such misstatements or omissions that are not reasonably likely to have a Material Adverse Effect on Acquirer.

        3.11.           No Indemnification Claims. To the knowledge of Acquirer, there has been no event, action, or omission by or with respect to any director, officer, employee, trustee, agent, or other person who may be entitled to receive indemnification or reimbursement of any claim, loss, or expense under any agreement, contract, or arrangement providing for corporate indemnification or reimbursement of any such person.

        3.12.           Conduct of Business. Each of Acquirer and the subsidiaries has conducted its business and used its properties in compliance with all federal, state, and local laws, civil or common, ordinances and regulations, including without limitation applicable federal and state laws and regulations concerning banking, securities, truth-in-lending, truth-in-savings, mortgage origination and servicing, usury, fair credit reporting, consumer protection, privacy, occupational safety, fair lending, civil rights, employee protection, fair employment practices, fair labor standards, real estate settlement and procedures, and insurance; and Environmental Laws (defined below); except for violations (individually or in the aggregate) that would not have a Material Adverse Effect on Acquirer.

14

        3.13.           Proxy Statement, Etc.

        3.13.1       Transaction Documents. The term “Transaction Documents” shall collectively mean: (i) the Form S-4 registration statement to be filed by Acquirer with the SEC (the “Registration Statement”) in connection with the Acquirer Common Stock to be issued in the Merger; (ii) the prospectus and proxy statement (the “Prospectus and Proxy Statement”) to be mailed to ICNB shareholders in connection with its shareholders’ meeting to consider approval of the Merger; and (iii) any other documents to be filed with the SEC, the Federal Reserve Board, the Office of the Comptroller of the Currency, the Michigan Office of Financial and Insurance Services, the State of Michigan, or any other regulatory agency in connection with the Merger.

        3.13.2       Accurate Information. The information to be supplied by Acquirer for inclusion or incorporation by reference in any Transaction Document will not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (a) at the respective times such Transaction Documents are filed; (b) with respect to the Registration Statement, when it becomes effective; and (c) with respect to the Prospectus and Proxy Statement, when it is mailed and at the time of the meeting of the shareholders of ICNB with respect to the Merger (the “Shareholders’ Meeting”).

        3.13.3       Compliance of Filings. All Transaction Documents that Acquirer is responsible for filing with the SEC or any regulatory agency in connection with the Merger will comply as to form in all material respects with the provisions of applicable law and regulation.

        3.14.           Agreements with Bank Regulators. Neither Acquirer nor any of its subsidiaries is a party to any agreement or memorandum of understanding with, or a party to any commitment letter, board resolution or similar undertaking to, or is subject to any order or directive by, or is a recipient of any extraordinary supervisory letter from, any governmental authority that restricts materially the conduct of its business, or is material and in any manner relates to its capital adequacy, its credit or reserve policies or its management, nor has Acquirer nor any of its subsidiaries been advised by any governmental authority that it is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, agreement, memorandum of understanding, extraordinary supervisory letter, commitment letter or similar submission, except where such order, decree, agreement, memorandum of understanding, extraordinary supervisory letter, commitment letter or similar submission are not reasonably likely to have a Material Adverse Effect on Acquirer. Neither Acquirer nor any of its subsidiaries is required by applicable law to give prior notice to any Federal banking agency of the proposed addition of an individual to its Board of Directors or the employment of an individual as a senior or executive officer. As of the date of this Plan of Merger, Acquirer knows of no reason why the regulatory approvals referred to in Section 3.1.4 (Required Approvals) cannot be obtained or why the process would be materially impeded.

15

        3.15.           Tax Matters. Each of Acquirer and its subsidiaries has duly filed all federal, state, foreign and local information returns and Tax Returns (defined below) required to be filed by it on or prior to the date of this Plan of Merger (all such returns being accurate and complete in all material respects) and has duly paid or made provision for the payment of all Taxes that have been incurred or are due or claimed to be due from it by federal, state, foreign or local taxing authorities other than (i) Taxes or other governmental charges that are not yet delinquent or are being contested in good faith, have not been finally determined and have been adequately reserved against, or (ii) information returns, Tax Returns or Taxes as to which the failure to file, pay or make provision for is not reasonably likely to have, either individually or in the aggregate, a Material Adverse Effect on Acquirer.

        3.16.           Investment Bankers and Brokers. Acquirer has not employed any broker, finder, or investment banker in connection with the Merger except Austin Associates, LLC. Acquirer has no other express or implied agreement with any other person or company relative to any commission or finder’s fee payable with respect to this Plan of Merger or the transactions contemplated by it.

        3.17.           Necessary Capital. Based on the financial condition of Acquirer as reflected in Acquirer’s Financial Statements, Acquirer has the necessary capital required by the regulations of the Federal Reserve Board and the Federal Deposit Insurance Corporation to consummate the transactions contemplated by this Plan of Merger and remain “well-capitalized” according to applicable banking laws and regulations. If external financing is required by Acquirer to consummate the transactions contemplated in this Plan of Merger, Acquirer has or will provide to ICNB sufficient adequate evidence of a binding commitment between Acquirer and its financing source.

        3.18.           Reorganization. Acquirer has no knowledge of any reason why the Merger would fail to qualify as a reorganization under Section 368(a) of the Internal Revenue Code.

        3.19.           Allowance for Loan Losses. The allowance for loan losses as reflected in Acquirer’s Financial Statements and Call Reports for the fiscal year ended December 31, 2005, and the fiscal quarter ended September 30, 2006, was in the reasonable opinion of management (a) adequate to meet all reasonably anticipated loan and lease losses, net of recoveries related to loans previously charged off as of those dates, and (b) consistent with GAAP and safe and sound banking practices.

        3.20.           Public Communications; Securities Offering. Each annual report, quarterly report, proxy material, press release, or other communication previously sent or released by Acquirer to Acquirer’s shareholders or the public did not contain any untrue statement of material fact or omit a statement of material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except for any such misstatement or omission that is not reasonably likely to have a Material Adverse Effect on Acquirer.

        3.21.           Fairness Opinion. Acquirers’ Board of Directors have received an oral opinion of Austin Associates, LLC (“Austin”) in its capacity as Acquirer’s financial adviser, substantially to the effect that the terms of the Merger are fair to Acquirer’s shareholders and Austin shall deliver a written opinion containing substantially the same opinion as its oral opinion dated as of the date of this Plan of Merger and renewed as of a date of approximately the date of the Prospectus and Proxy Statement. A true and complete copy of the written opinion of Austin confirming the same will be provided to ICNB promptly upon receipt by Acquirer.

                Except as disclosed in a correspondingly numbered section of the disclosure schedule (the “ICNB Disclosure Statement”) delivered by ICNB to Acquirer prior to the execution of this Agreement, ICNB represents and warrants to Acquirer as follows; provided, however, the disclosure in the ICNB Disclosure Statement of an item or matter in response or in reference to one provision or representation shall be deemed responsive to other provisions and representations where the applicability of such item or matter to other provision(s) is reasonably apparent:

To the knowledge of ICNB, there is no factual basis for any valid claim or charge with regard to such employment-related matters that could result in a loss to ICNB or the Subsidiaries which would have a Material Adverse Effect on ICNB.

        4.21.4       Plan Termination. No Employee Benefit Plan that is a qualified plan under Section 401(a) of the Internal Revenue Code and no trust created thereunder has been terminated, partially terminated, curtailed, discontinued, or merged into another plan or trust after January 1, 1997, except in compliance with notice and disclosure to the IRS and the Pension Benefit Guaranty Corporation (the “PBGC”), where applicable, as required by the Internal Revenue Code and ERISA. With respect to each plan termination, all termination procedures have been completed and there is no pending or potential liability to the PBGC, to any plan, or to any participant under the terminated plan. Each plan termination, partial termination, curtailment, discontinuance, or consolidation has been accompanied by the issuance of a current favorable determination letter by the IRS and, where applicable, has been accompanied by plan termination proceedings with and through the PBGC.

        4.21.8       Payment of Benefits. There is no payment that has become due from any Employee Benefit Plan, any trust created thereunder, or from ICNB or any Subsidiary that has not been paid through normal administrative procedures to the plan participants or beneficiaries entitled thereto, except for claims for benefits for which administrative claims procedures under such plan have not been exhausted.

        4.21.9       Accumulated Funding Deficiency. No Employee Benefit Plan that is intended to be a qualified plan under Section 401(a) of the Internal Revenue Code and no trust created thereunder has incurred, subsequent to June 30, 1974, an “accumulated funding deficiency” as defined in Section 412(a) of the Internal Revenue Code and Section 302 of ERISA (whether or not waived).

        4.21.10        Funding. Neither ICNB nor any Subsidiary owes premiums to the PBGC that are due but unpaid or has been determined by the PBGC to be liable for a funding deficiency with respect to a plan termination under Title IV of ERISA.

        4.21.11       Filing of Reports. Each of ICNB and the Subsidiaries have filed or caused to be filed, and will continue to file or cause to be filed, in a timely manner all filings pertaining to each Employee Benefit Plan with the IRS, the United States Department of Labor, and the PBGC as prescribed by the Internal Revenue Code, ERISA, and the regulations issued thereunder. All such filings, as amended, were complete and accurate in all material respects as of the dates of such filings, and there were no material misstatements or omissions in any such filing which would have a Material Adverse Effect.

        (a)        Construction and Content. To the knowledge of ICNB, none of the Premises is constructed of, or contains as a component part, any material that (either in its present form or as it may reasonably be expected to change through aging or normal use) releases or may release any Hazardous Substance. Without limiting the generality of this Section, to the knowledge of ICNB, the Premises are free of asbestos except to the extent properly sealed or encapsulated if and to the extent required by all applicable Environmental Laws and all applicable workplace safety and health laws and regulations.

        (b)        Uses of Premises. To the knowledge of ICNB, no part of the Premises has been used for the generation, manufacture, handling, containment, treatment, transportation, storage, disposal, or management of Hazardous Substances, except for storage of normal quantities of office supplies and customary cleaning and maintenance products.

        (c)        Underground Storage Tanks. To the knowledge of ICNB the Premises do not contain and have never contained any underground storage tanks.

There is no action, suit, investigation, liability, inquiry, or other proceeding, ruling, order, notice of potential liability, or citation involving ICNB or any Subsidiary that is pending, previously asserted or, to ICNB’s knowledge, threatened under, or as a result of any actual or alleged failure to comply with any requirement of, any Environmental Law. To ICNB’s knowledge, there is no basis for any of the foregoing.

30

        (f)        Environmental Reports. ICNB has provided Acquirer with copies of any and all reports, data, information and documents in its possession or control relating to contamination, potential contamination or other environmental conditions or other environmental conditions at, on, under or from the Premises.

        4.22.2       Loan Portfolio. With respect to any real estate securing any outstanding loan and any owned real estate acquired in full or partial satisfaction of a debt previously contracted, to the knowledge of ICNB, the Bank has complied in all material respects with its policies, if any (as such policies may have been in effect from time to time and as disclosed in the ICNB Disclosure Statement), and all applicable laws and regulations, concerning the investigation of each such property to determine whether or not there exists or is reasonably likely to exist any Hazardous Substance on, in, or under such property at a level giving rise to material liability of ICNB or the Bank and whether or not a release of a Hazardous Substance has occurred at or from such property.

        4.22.3       Environmental Laws; Hazardous Substance.

        4.23.           Duties as Fiduciary. To the knowledge of ICNB, the Bank has performed all of its duties in any capacity as trustee, executor, administrator, registrar, guardian, custodian, escrow agent, receiver, or other fiduciary in a fashion that complies in all material respects with all applicable laws, regulations, orders, agreements, ▇▇▇▇▇, instruments, and common law standards. The Bank has not received notice of any claim, allegation, or complaint from any person that the Bank failed to perform these fiduciary duties in a manner that complies in all material respects with all applicable laws, regulations, orders, agreements, ▇▇▇▇▇, instruments, and common law standards, except for notices involving matters that have been resolved and any cost of such resolution is reflected in ICNB’s Financial Statements.

        4.24.           Investment Bankers and Brokers. ICNB has employed SAMCO Capital Markets, Inc. (“SAMCO”) in connection with the Merger. ICNB, the Subsidiaries, and their respective affiliates, directors, officers, investment bankers, attorneys, and agents (collectively, “ICNB’s Representatives”) have not employed, engaged, or consulted with any broker, finder, or investment banker other than SAMCO in connection with this Plan of Merger or the Merger. Other than the fees and expenses payable by ICNB to SAMCO in connection with the Merger, as described in the ICNB Disclosure Statement, there is no investment banking fee, financial advisory fee, brokerage fee, finder’s fee, commission, or compensation payable by ICNB or any Subsidiary to any person with respect to the Plan of Merger or the consummation of the Merger.

31

        4.25.           Fairness Opinion. ICNB’s Board of Directors has received an oral opinion of SAMCO in its capacity as ICNB’s financial advisor, substantially to the effect that the consideration to be received by the holders of the ICNB Common Stock in the Merger is fair to the holders of ICNB Common Stock from a financial point of view.

        4.26.           ICNB-Related Persons. For purposes of this Plan of Merger, the term “ICNB-Related Person” shall mean any person or entity who or which is an “Insider” as defined in Regulation O, section 2.15.2(h).

        4.26.1       Insider Loans. No ICNB-Related Person has any loan, credit or other contractual arrangement outstanding with ICNB or the Subsidiaries that does not conform to any applicable rules and regulations of the FDIC or the Federal Reserve Board.

        4.26.2       Control of Material Assets. Other than in a capacity as a shareholder, director, or executive officer of ICNB or a Subsidiary, no ICNB-Related Person owns or controls any assets or properties that are used in the business of ICNB or any Subsidiary.

To its knowledge, ICNB has not received written notification that any customer, agent, representative, supplier of ICNB or any Subsidiary, or other person with whom ICNB or any Subsidiary has a contractual relationship, intends to discontinue, diminish, or change its relationship with ICNB or any Subsidiary, the effect of which would have a Material Adverse Effect on ICNB.

        4.28.           Insurance. ICNB and each Subsidiary maintains in full force and effect insurance on their respective assets, properties, premises, operations, and personnel in such amounts and against such risks and losses as are believed to be customary and adequate for comparable entities engaged in the same business and industry. There is no pending unsatisfied claim of $100,000 or more under such insurance as to which the insurance carrier has denied liability. During the last five years, no insurance company has canceled or refused to renew a policy of insurance covering ICNB or any Subsidiaries’ assets, properties, premises, operations, directors or personnel. ICNB and the Subsidiaries have given adequate and timely notice to each insurance carrier, and have complied with all policy provisions, with respect to any material known claim for which a defense and/or indemnification may be available to ICNB or the Subsidiaries.

32

The corporate minute books of ICNB and the Subsidiaries contain accurate and adequate records of all corporate actions actually taken by their shareholders, board of directors, and committees of the board of directors in all material respects. Since January 1, 2002, the minutes of each meeting (or corporate action without a meeting) of any such shareholders, boards, or committees have been duly prepared and are contained in such minute books. All such minute books and related exhibits or attachments for all meetings since January 1, 2002, have been made available for Acquirer’s review prior to the date of this Plan of Merger without material omission or redaction (other than with respect to the minutes relating to the Merger or recent and similarly proposed transactions).

        4.30.           Loan Guarantees. All guarantees of indebtedness owed to ICNB or any Subsidiary, including without limitation those of the Federal Housing Administration, the Small Business Administration, and other state and federal agencies, are valid and enforceable, except as limited by bankruptcy, insolvency, moratorium, reorganization, or similar laws affecting the rights of creditors generally and the availability of equitable remedies and except where such unenforceability is not reasonably likely to have a Material Adverse Effect on ICNB.

        4.31.           Events Since January 1, 2006. Neither ICNB nor any Subsidiary has, since January 1, 2006:

33

        4.31.4       Mortgage of Assets. Mortgaged, pledged, or subjected to lien, charge, or other encumbrance any of its assets, or sold or transferred any such assets, except in the ordinary course of business, except for any single mortgage, pledge, lien, charge, and encumbrance for indebtedness that does not exceed $100,000 or for the aggregate of any group of mortgages, pledges, liens, charges, and encumbrances for indebtedness that do not in the aggregate exceed $200,000.

The allowance for loan losses as reflected in ICNB’s Financial Statements and Call Reports for the fiscal year ended December 31, 2005, and the fiscal quarter ended September 30, 2006, was in the reasonable opinion of management (a) adequate to meet all reasonably anticipated loan and lease losses, net of recoveries related to loans previously charged off as of those dates, and (b) consistent with GAAP and safe and sound banking practices.

        4.33.           Loan Origination and Servicing.

        4.35.           No ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇. ICNB has reviewed its stock transfer records since January 1, 2006, and has inquired of its directors and executive officers concerning known stock transfers since that date. Based upon that investigation, ICNB has not, and to ICNB’s knowledge (a) no director or officer of ICNB, (b) no person related to any such director or officer by blood or marriage and residing in the same household, and (c) no person who has been knowingly provided material nonpublic information by any one or more of these persons, has purchased or sold, or caused to be purchased or sold, any shares of ICNB Common Stock or other securities issued by ICNB during any period when ICNB was in possession of material nonpublic information in violation of any applicable provision of federal or state securities laws.

ICNB, acting through its Board of Directors, shall, in accordance with the Michigan Act and its Articles of Incorporation and Bylaws, promptly and duly call, give notice of, convene, and hold the Shareholders’ Meeting as soon as practicable following the date of this Plan of Merger.

        5.4.1       Board Recommendation. Except while ICNB has received in writing a Superior Proposal (defined below) that is still pending, at the Shareholders’ Meeting and in any proxy materials used in connection with the meeting, the Board of Directors of ICNB shall recommend that its shareholders vote for approval of this Plan of Merger and the Merger.

        5.4.2        Solicitation of Proxies. Except while a Fiduciary Event (defined below) has occurred and continues:

        (a)        ICNB shall use all reasonable efforts to solicit from its shareholders proxies to vote on the proposal to approve this Plan of Merger and to secure a quorum at the Shareholders’ Meeting.

        (b)        Except while ICNB has received in writing a Superior Proposal that is still pending, ICNB shall use its reasonable efforts to secure the vote of shareholders required by the Michigan Act and ICNB’s Articles of Incorporation and Bylaws to approve this Plan of Merger.

        5.4.3       Fiduciary Event. A “Fiduciary Event” shall have occurred when the Board of Directors of ICNB has (a) received in writing a Superior Proposal that is then pending, (b) determined in good faith (having considered the advice of legal counsel) that its fiduciary duties to ICNB’s shareholders under applicable law would require the Board of Directors to withdraw, modify, or change its recommendation, and (c) determined to accept and recommend the Superior Proposal to the shareholders of ICNB.

        5.4.4       Superior Proposal. A “Superior Proposal” means any bona fide unsolicited Acquisition Proposal (as defined in Section 5.8.1 (No Solicitation)) made by a third party on terms that the Board of Directors of ICNB determines in its good faith judgment, having considered the advice of SAMCO or another financial advisor of recognized standing, to be materially more favorable to ICNB’s shareholders than this Plan of Merger from a financial point of view after taking into account the likelihood of consummation of such transaction on the terms set forth therein, taking into account all legal, 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, rule or regulation.

40

        5.4.5       Notice. ICNB shall notify Acquirer at least ten (10) Business Days prior to taking any action with respect to such Superior Proposal or taking any action with respect to the withdrawal, modification, or change of its recommendation to its shareholders for approval of this Plan of Merger.

        5.5.           Regular Dividends. ICNB shall not declare, set aside, pay, or make any dividend or other distribution or payment (whether in cash, stock, or property) with respect to, or purchase or redeem, any shares of ICNB Common Stock other than regular annual cash dividends on ICNB Common Stock in an amount not to exceed a quarterly rate of $0.23 per share in a manner consistent with ICNB’ s past dividend practice; provided, however, that no dividend will be paid if the Bank is not well capitalized or if the payment of such dividend would cause the Bank not to be well capitalized.

        5.6.           Technology-Related Contracts. Until the Effective Time, ICNB shall advise Acquirer of all anticipated renewals or extensions of material existing data processing service agreements, data processing software license agreements, data processing hardware lease agreements, and other material technology-related licensing, maintenance or servicing agreements with independent vendors (“Technology-Related Contracts”) involving ICNB or any Subsidiary. The material Technology-Related Contracts of ICNB and its Subsidiaries are contained in the ICNB Disclosure Statement. Notwithstanding any other provision of this Section 5.6, neither ICNB nor any Subsidiary shall be obligated to take any irrevocable action, or irrevocably forego taking any action, with respect to those Technology-Related Contracts that would cause any such agreement to terminate, expire, or be materially modified prior to the Effective Time.

        5.6.1       Contract Notices. ICNB or its Subsidiaries shall send to each vendor, as and when permitted after the date of this Plan of Merger, such notices of nonrenewal as may be necessary or appropriate under the terms of these Technology-Related Contracts to prevent them from automatically renewing for a term extending beyond the Effective Time except if such agreement is reasonably believed to be necessary for ICNB or a Subsidiary to conduct business in the ordinary course. Such notices may be conditioned upon the consummation of the Merger.

        5.6.2       Extensions and Renewals. ICNB and its Subsidiaries shall cooperate with Acquirer in negotiating with each vendor the length of any new, extension, or renewal term of these Technology-Related Contracts in those cases where such extension or term extends beyond the Effective Time.

        5.6.3       New Agreements. Neither ICNB nor any Subsidiary shall enter into any new Technology-Related Contract, except with Acquirer’s consent (which consent shall not be unreasonably withheld or delayed if such agreement is reasonably believed to be necessary for ICNB or a Subsidiary to conduct business in the ordinary course).

41

        5.7.           Indemnification and Insurance.

        5.7.1       Indemnification. Acquirer shall honor any and all rights to indemnification and advancement of expenses now existing in favor of the present and former directors and officers of ICNB or any Subsidiary under its Articles of Incorporation, articles of organization, charter, or Bylaws included in the ICNB Disclosure Statement which, as enforceable contractual rights, shall survive the Merger and shall, as contractual rights, continue with respect to acts or omissions occurring before the Effective Time with the same force and effect as prior to the Effective Time. This Section 5.7 (Indemnification and Insurance) is for the benefit of persons who are or have been directors or officers of ICNB and its Subsidiaries and shall be enforceable by and only by such persons and their estates and personal representatives.

        5.7.2       Insurance. Acquirer shall use all commercially reasonable efforts to cause the persons currently serving or having served as officers and directors of ICNB immediately prior to the Effective Time to be covered for a period of at least six years from the Effective Time by the directors’ and officers’ liability insurance policy maintained by ICNB or any Subsidiary with respect to acts or omissions occurring prior to the Effective Time that were committed by such officers and directors in their capacity as such. Acquirer may substitute, for ICNB’s current coverage, (a) coverage under policies maintained by Acquirer that offer comparable or better coverage and amounts, and that contain terms and conditions that, considered in the aggregate, are not materially less advantageous to the directors and officers than ICNB’s current policy, and (b) an undertaking by Acquirer to maintain such coverage for the remaining period of the six year period provided for by this Section. In no event shall Acquirer be required to spend, directly or indirectly through ICNB or a Subsidiary, more than $150,000 in the aggregate (the “Insurance Amount”) to either maintain or procure insurance coverage pursuant to this Plan of Merger. Coverage under Acquirer’s policy shall not be considered “materially less advantageous” than ICNB’s policy because of a higher deductible amount if Acquirer undertakes in writing to pay any difference in deductible amounts. If Acquirer does not advise ICNB in writing prior to the Shareholders’ Meeting that it has procured such coverage and that it undertakes to procure and maintain coverage that offers comparable or better coverage and amounts, and that contains terms and conditions that, considered in the aggregate, are not materially less advantageous than ICNB’s current policy for the remaining period of the six year period provided for by this Section without regard to the insurance Amount, ICNB shall be permitted (after giving Acquirer three Business Days prior written notice and an additional two Business Day period to purchase such coverage), in lieu of receiving the foregoing insurance coverage, to procure tail coverage for past acts and omissions for a single premium amount not in excess of the Insurance Amount. This Section 5.7 is for the benefit of persons who are or have been directors or officers of ICNB or any subsidiary and shall be enforceable by such persons and their estates and personal representatives.

        5.8.           Exclusive Commitment. Except as provided below or otherwise permitted by this Plan of Merger, neither ICNB nor any of ICNB’s Representatives shall take any action inconsistent with the intent to consummate the Merger upon the terms and conditions of this Plan of Merger. Without limiting the foregoing:

42

        5.8.1       No Solicitation. Neither ICNB nor any of ICNB’s Representatives, shall, directly or indirectly, (i) invite, initiate, solicit, or encourage an Acquisition Proposal; or (ii) participate in any discussions or negotiations regarding an Acquisition Proposal unless a Fiduciary Event has occurred and continues or such discussions or negotiations are reasonably believed to be reasonably likely to lead to a Superior Proposal. A proposal, offer, or other expression of interest concerning an Acquisition Transaction (defined below) shall be referred to as an “Acquisition Proposal.” For purposes of this Plan of Merger, an “Acquisition Transaction” means: (a) a merger, consolidation, share exchange, tender offer, exchange offer, sale of shares or any similar transaction, involving ICNB or any of the Subsidiaries other than the Merger; (b) a transaction involving purchase, lease or other acquisition of all or a majority of the assets and assumption of a majority of the deposits and other liabilities of ICNB and its Subsidiaries on a consolidated basis not in the ordinary course; (c) a purchase or other acquisition (including by way of merger, consolidation, share exchange or otherwise) of securities representing 40% or more of the voting power of ICNB; or (d) any substantially similar transaction.

        5.8.2       Communication of Other Proposals. ICNB shall cause written notice to be delivered to Acquirer promptly upon receipt of any Acquisition Proposal. Such notice shall contain the material terms and conditions of the Acquisition Proposal to which such notice relates. Within ten Business Days after ICNB’s receipt of an Acquisition Proposal, ICNB shall give notice to Acquirer whether or not a Fiduciary Event has occurred or a Superior Proposal is reasonably likely to result, and if not, ICNB’s notice shall include a copy of ICNB’s unequivocal rejection of the Acquisition Proposal in the form actually delivered to the person from whom the Acquisition Proposal was received. Thereafter, ICNB shall promptly notify Acquirer of any material changes in the terms, conditions, and status of such Acquisition Proposal.

        5.8.3       Furnishing Information. Unless a Fiduciary Event has occurred and continues or ICNB reasonably believes that there is a reasonable likelihood that a Superior Proposal would result, neither ICNB nor any of ICNB’s Representatives shall furnish any nonpublic information concerning ICNB or any Subsidiary to any person who is not affiliated or under contract with ICNB or Acquirer, except as required by applicable law, regulations or fiduciary duties. Prior to furnishing such information to any person who is not affiliated or under contract with ICNB or Acquirer, a Fiduciary Event must have occurred and ICNB shall receive from such person an executed confidentiality agreement with terms no less favorable to ICNB than those contained in its confidentiality agreement with Acquirer and ICNB shall then provide only such information as has been furnished previously to Acquirer.

        5.8.4       Corporate Liability for Individual’s Breach. For the purposes of this Section, any breach of this Section by an executive officer, director, attorney or financial advisor of ICNB in his or her individual capacity shall be deemed to be a breach by ICNB.

        5.9.           Other Filings. Acquirer shall prepare and file with the Federal Reserve Board and each other regulatory agency having jurisdiction all documents reasonably required to obtain each necessary approval of or consent to consummate the Merger. Acquirer shall provide ICNB with reasonable opportunities to review and comment upon such documents before filing and to make such amendments and file such supplements thereto as ICNB may reasonably request. Acquirer shall provide ICNB with copies of all material correspondence received from these agencies and all material responsive correspondence sent to these agencies.

43

        5.10.           Miscellaneous Agreements and Consents. Subject to the terms and conditions of this Plan of Merger, each of the parties shall use all 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. The parties will use all reasonable efforts to obtain consents of all third parties and governmental bodies necessary or desirable for the consummation of the Merger.

        5.11.           Registration Statement. Acquirer shall prepare and file with the SEC under the Securities Act, the Registration Statement and the related Prospectus and Proxy Statement included as a part thereof covering the issuance by Acquirer of the shares of Acquirer Common Stock as contemplated by this Plan of Merger, together with such amendments as may reasonably be required before the Registration Statement becomes effective. Acquirer shall provide ICNB with reasonable opportunities to review and comment upon the Registration Statement, each amendment to the Registration Statement and each form of Prospectus and Proxy Statement before filing. Acquirer shall provide ICNB, upon request, copies of all correspondence received from the SEC with respect to the Registration Statement and its amendments and with all responsive correspondence to the SEC. Acquirer shall notify ICNB of any stop orders or threatened stop orders with respect to the Registration Statement. ICNB shall provide to Acquirer all necessary information pertaining to ICNB promptly upon request, and to use all reasonable efforts to obtain the cooperation of ICNB’s independent accountants, attorneys and investment bankers in connection with the preparation of the Registration Statement. In the Prospectus and Proxy Statement, Acquirer shall indicate that forward looking information and financial projections have been prepared by and are the responsibility of Acquirer.

        5.12.           Access and Investigation. Between the date of the Plan of Merger and the Closing, for the purpose of permitting an examination of ICNB by Acquirer’s officers, attorneys, accountants, and representatives, ICNB shall:

        5.12.1       Access. Permit, and shall cause each of its Subsidiaries to permit, full access to their respective properties, books, and records at reasonable times.

        5.12.2       Cooperation. Use reasonable efforts to cause its and each of its Subsidiaries’officers, directors, employees, accountants, and attorneys to cooperate fully, for the purpose of permitting a complete and detailed examination of such matters by Acquirer’s officers, attorneys, accountants, and representatives.

        5.12.3       Information. Furnish Acquirer, upon reasonable request, any information respecting its and each of its Subsidiaries’ properties, assets, business, and affairs.

44

        5.12.4       Consents. Acquirer acknowledges that certain information may not be disclosed by ICNB without the prior written consent of persons not affiliated with ICNB or its Subsidiaries. If such information is requested, then ICNB shall use reasonable efforts to obtain such prior consent and shall not be required to disclose such information unless and until such prior consent has been obtained.

        5.12.5       Return and Retention. In the event of termination of this Plan of Merger, Acquirer agrees to promptly return or to destroy all written materials furnished to it by ICNB and its Subsidiaries, and all copies, notes, and summaries of such written materials. ICNB agrees to preserve intact all such materials that are returned to it and to make such materials reasonably available upon reasonable request or subpoena for a period of not less than six years from the termination of this Plan of Merger.

        5.13.           Confidentiality. Except as provided below, Acquirer and ICNB each agree:

        5.13.1       Treatment; Restricted Access. All information furnished to the other party pursuant to this Plan of Merger shall be treated as strictly confidential and shall not be disclosed to any other person, natural or corporate, except for its employees, attorneys, accountants, regulators, and financial advisers who are reasonably believed to have a need for such information in connection with the Merger.

        5.13.2       No Other Use. No party shall make any use, other than related to the Merger, of any information it may come to know as a direct result of a disclosure by the other party, its subsidiaries, directors, officers, employees, attorneys, accountants, or advisers or that may come into its possession from any other confidential source during the course of its investigation.

        5.13.3       Excepted Information. The provisions of this Section shall not preclude the parties or their respective subsidiaries, from using or disclosing information that is readily ascertainable from public information or trade sources, known by it before the commencement of discussions between the parties or subsequently developed by it or its subsidiaries independent of any investigation under this Plan of Merger, received from any other person who is not affiliated with a party and who is not under any obligation to keep such information confidential, or reasonably required to be included in any filing or application required by any governmental or regulatory agency.

        5.13.4       Prohibit ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇. The parties shall each take responsible steps to assure that any person who receives nonpublic information concerning the Merger or the other party will treat the information confidentially as provided in this Section and not directly or indirectly buy or sell, or advise or encourage other persons to buy or sell, ICNB’s stock until such information is properly disclosed to the public.

        5.14.           Environmental Investigation.

        5.14.1       Investigation. Acquirer shall be permitted to conduct and obtain not later than thirty (30) Business Days after the date of this Plan of Merger (or within 30 Business Days after the acquisition or lease of any real property acquired or leased after the date of this Plan of Merger) a report of a phase one environmental assessment of: (a) any or all parcels included in the Premises; (b) to the extent permitted by the current owners or operators thereof, any other real estate formerly owned by ICNB or any Subsidiary; and (c) any other real estate acquired by any Subsidiary in satisfaction of a debt previously contracted. Upon request, ICNB and its Subsidiaries shall provide reasonable assistance, including site access, a knowledgeable contact person, documentation relating to the real estate, and any prior environmental investigations or reports in ICNB’s possession to Acquirer’s consultant for purposes of conducting the phase one assessments.

45

        5.14.2       Environmental Risk. If there are any facts or conditions identified in a phase one assessment or in any other reports or other documents disclosed by ICNB or otherwise obtained by Acquirer that Acquirer reasonably believes could pose a current or future risk of material liability to ICNB or Acquirer (“Environment Risk”), then Acquirer shall identify the Environmental Risk to ICNB, identify the facts or conditions underlying that risk, and provide ICNB with a copy of the phase one assessment or other reports or documents relating to the Environmental Risk unless already in the possession of ICNB.

        5.14.3       Remediation Estimate. Upon receipt of all notice(s) of Environmental Risk, the parties shall jointly retain a qualified environmental consultant (the “Joint Environmental Consultant”) to perform an investigation of the environmental condition of the relevant portion(s) of the Premises (the “Environmental Investigation”). Based on the results of the Environmental Investigation, the Joint Environmental Consultant shall prepare an estimate of the cost of taking all investigative, remedial or other corrective actions and measures (the “Remediation Estimate”) that are required of ICNB or Acquirer by any Environmental Laws, including applicable cleanup standards, or reasonably likely to be required by applicable law. In the event that Acquirer requests that ICNB submit one or more baseline environmental assessments (“BEA”) to the Michigan Department of Environmental Quality (“MDEQ”) for any property consistent with Section 5.14.9 (below), the Joint Environmental Consultant shall not prepare a Remediation Estimate for that property unless either: (i) ICNB has failed to obtain a written determination of adequacy from the MDEQ with regard to the BEA(s) prior to the Remediation Cost Deadline (as that term is defined below), or (ii) the MDEQ has conclusively denied the adequacy of the BEA(s). In the event that ICNB obtains a written determination of adequacy for any property prior to the Remediation Cost Deadline (as that term is defined below), the Joint Environmental Consultant shall not prepare a Remediation Estimate for that property, and there shall be no adjustment to the Merger Consideration for that property under Section 5.14.8(b) below.

        5.14.4       Estimate of Potential Liability. Upon Acquirer’s request, the Joint Environmental Consultant shall prepare an estimate of the cost of all investigative, remedial or other corrective actions and measures that could be required under any relevant Environmental Laws (the “Estimate of Potential Environmental Liability”) for each Environmental Risk. In calculating the amount of the Estimate of Potential Environmental Liability, the Joint Consultant shall assume that neither ICNB nor the Acquirer would have a valid legal defense to potential environmental liability under any relevant Environmental Laws.

46

        5.14.5       Scope of the Environmental Investigation. The Joint Environmental Consultant shall undertake all Environmental Investigation necessary to allow for the preparation of a reasonably accurate Remediation Estimate and Estimate of Potential Liability for each Environmental Risk identified.

        5.14.6       Joint Consultant Fees. The parties shall share equally in any fees, costs and/or expenses charged by the Joint Environmental Consultant relating to or resulting from work or services performed pursuant to this Plan of Merger except those fees, costs or expenses relating to or resulting from matters set forth in Sections 5.14.10 (Removal of Underground Storage Tanks) and 5.14.11 (Baseline Environmental Assessments), which shall be at the sole cost and expense of ICNB.

        5.14.7       Remediation Cost. Each party shall have five (5) business days after receipt of the Remediation Estimate to provide the other party with a written objection, which shall state in reasonable detail the basis for such objection. If neither party has provided such a written objection within five (5) business days of receipt of the Remediation Estimate, the Remediation Estimate shall be deemed the Remediation Cost for the Purposes of this Plan of Merger. If either party provides a written objection as set forth above, the parties shall engage in good faith discussions to reach agreement on the Remediation Cost for a time period not to exceed ten (10) business days. If the parties are unable to reach agreement on the Remediation Cost then two environmental experts, one of whom shall be appointed by the Acquirer and the other of whom shall be appointed by ICNB, shall each prepare an independent Remediation Estimate (each, such estimate an “Independent Remediation Estimate”) within ten (10) business days, which they shall immediately submit in writing to the Acquirer and ICNB. If each such Independent Remediation Estimate is within 10% of the numerical average of both such estimates, then the Remediation Cost shall be determined by taking the numerical average of both such estimates. If each such Independent Remediation Estimate is not within 10% of the numerical average of both such estimates, then the two environmental experts shall within ten (10) days after such ten (10) day period, mutually select and appoint a third environment expert (the “Third Party Expert”), similarly qualified, and give written notice thereof to the Acquirer and ICNB. Within fifteen (15) days after the appointment of the Third Party Expert, the three (3) experts shall each submit their Remediation Estimates in writing to the Acquirer and ICNB, and the Remediation Cost shall be determined by taking the numerical average of the two estimates that are closest together.

        9.1.        “Material Adverse Effect” Defined. As used in this Plan of Merger, the term “Material Adverse Effect” means any change or effect that, individually or when taken together with all other such changes or effects that have occurred prior to the date of determination of the occurrence of the Material Adverse Effect, has had or could have a material negative impact on the business, assets, financial condition, results of operations, properties or value of Acquirer and the Acquirer Subsidiaries, taken as a whole, or ICNB and the Subsidiaries, taken as a whole, as the case may be. Notwithstanding the above, the impact of the following shall not be included in any determination of a Material Adverse Effect: (a) changes in GAAP, generally applicable to financial institutions and their holding companies; (b) actions and omissions of a party (or any of its subsidiaries) taken with the prior written consent of the other party; (c) changes in economic conditions (including changes in the level of interest rates) generally affecting financial institutions; and (d) fees and expenses contemplated by this Plan of Merger reasonably related to the transaction contemplated in this Plan of Merger incurred or paid without violation of the representations, warranties or covenants in this Plan of Merger.

        9.2.        “Knowledge” Defined; “Person” Defined; “Affiliate” Defined. As used in this Plan of Merger, the term “Knowledge” or “to the knowledge of” means the actual knowledge of any director or officer (as the term “officer” is defined in Rule 16a-1 of the Exchange Act) of ICNB or Acquirer or their respective significant subsidiaries (as defined in SEC Regulation S-X), as the case may be. “Person,” whether or not capitalized, has the meaning set forth in Sections 3(a)(9) and 13(d)(3) of the Securities Act and shall also mean any association, partnership, limited liability company, limited partnership, trust, joint venture or other legal entity. “Affiliate” of, or a person “Affiliated” with (whether or not capitalized) means a specific person that directly or indirectly, through one or more intermediaries (by virtue of legal or beneficial ownership, contractual rights, or otherwise) controls, is controlled by, or is under common control with, the person specified.

        9.3.        Nonsurvival of Representations, Warranties, and Agreements. None of the representations, warranties, covenants, and agreements in this Plan of Merger or in any other agreement or instrument delivered pursuant to this Plan of Merger, including any rights arising out of any breach of such representations, warranties, covenants, and agreements, shall survive the Effective Time, except for the agreements attached as Exhibit B and Sections 5.7, 5.13, 5.21, and 5.22 to this Plan of Merger.

59

        9.4.           Amendment. Subject to applicable law, this Plan of Merger may be amended, modified, or supplemented by, and only by, written agreement of Acquirer and ICNB, executed by the respective authorized officers, at any time prior to the Effective Time.

        9.5.                         Expenses.

        9.6.        Specific Enforcement. The parties each agree that, consistent with the terms and conditions of this Plan of Merger, in the event of a breach by a party to this Plan of Merger, money damages will be inadequate and not susceptible of computation because of the unique nature of ICNB, its Subsidiaries, and the Merger. Therefore, the parties each agree that a federal or state court of competent jurisdiction shall have authority, subject to the rules of law and equity, to specifically enforce the provisions of this Plan of Merger by injunctive order or such other equitable means as may be determined in the court’s discretion.

Any of the terms or conditions of this Plan of Merger may be waived in writing at any time by action taken by the Board of Directors of a party, a duly authorized committee thereof, or a duly authorized officer of such party. The failure of any party at any time or times to require performance of any provision of this Plan of Merger shall in no manner affect such party’s right at a later time to enforce the same provision. No waiver by any party of any condition, or of the breach of any term, covenant, representation, or warranty contained in this Plan of Merger, whether by conduct or otherwise, in any one or more instances shall be deemed to be or construed as a further or continuing waiver of any such condition or breach, or as a waiver of any other condition or of the breach of any other term, covenant, representation, or warranty. 9.8.

EMPLOYMENT AGREEMENT

        This EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into this 1st day of February, 2007, by and among FIRSTBANK CORPORATION, a Michigan corporation (“Firstbank”), THE IONIA COUNTY NATIONAL BANK OF IONIA, a national bank of the United States of America (the “Bank”), and ▇▇▇▇▇ ▇. FAST (“Executive”).

        WHEREAS, Firstbank and ICNB Financial Corporation, the parent corporation of the Bank, are parties to an Agreement and Plan of Merger, dated February 1, 2007, whereby ICNB Financial Corporation shall merge with and into Firstbank (the “Merger”); and

        WHEREAS, the parties desire to enter into this Agreement, which is intended to set forth in its entirety the terms and conditions of the employment relationship between the Bank and Executive; and

        WHEREAS, this Agreement shall become effective if and only if the Merger is consummated, at which time it shall replace and supersede all prior employment and change of control agreements between the Executive and the Bank and/or ICNB Financial Corporation;

        NOW, THEREFORE, the parties agree as follows:

    1.        Effective Date and Term. This Agreement shall become effective if and only if the Merger takes place and shall automatically become effective at the Effective Time of the Merger, and shall expire on the third anniversary of the Effective Time. This Agreement and the simultaneously executed Management Continuity Agreement shall supersede all previous agreements and understandings pertaining to Executive’s employment with and compensation by the Bank, ICNB Financial Corporation, and/or Firstbank or any of their Affiliates, including, but not limited to, that certain Management Continuity Agreement dated February 7, 1999, by and between Executive and ICNB Financial Corporation (the “1999 Agreement”); provided, however, that this Agreement shall not terminate vested rights of Executive under the terms of any retirement, deferred compensation or benefit plan or arrangement that has been disclosed to Firstbank, nor shall this Agreement terminate any right of Executive to indemnification under the Articles or Bylaws of the Bank.

    2.        Employment. Executive is employed as the President and Chief Executive Officer of the Bank and to render such executive services consistent with that position to the Bank as may from time to time be reasonably directed by Firstbank’s Chief Executive Officer. In the event of elimination of the positions of President and Chief Executive Officer of the Bank as a result of consolidation of the Bank, Executive will be employed in another reasonably suitable executive position with duties as determined by Firstbank. Executive shall perform his duties under this Agreement in accordance with reasonable standards and policies established from time to time by the Board of Directors of Firstbank.

1

    3.        Cash Payment. Firstbank shall pay Executive a lump sum cash payment on January 2, 2008 in the amount of Three Hundred Fifty Thousand Dollars ($350,000), subject to any applicable withholding taxes, in lieu of any and all payments and benefits to which he would otherwise have been entitled under the 1999 Agreement. It is agreed that the obligation to make this payment is fixed and absolute, and that this payment is not subject to forfeiture or setoff of any kind whatsoever.

    4.        Compensation. Firstbank agrees to pay Executive a minimum base annual salary in the sum of One Hundred Forty Nine Thousand, Three Hundred Dollars ($149,300) (“Base Salary”). The Base Salary provided herein shall be payable in accordance with the periodic payment procedures for all executives of the Bank. Base Salary may be increased by Firstbank each year in its discretion. Executive’s salary shall be subject to the applicable withholding taxes required with respect to compensation paid by a corporation to an Executive. Executive will not receive any additional compensation for service on the Board of Directors of the Bank or any of its subsidiaries.

    5.        Annual Incentive Compensation. In addition to the Base Salary provided for in Section 4, Executive shall be entitled to earn Annual Incentive Compensation as may be from time to time authorized and declared by the Board of Directors of Firstbank for the benefit of Firstbank’s bank presidents.

    6.        Benefits. Executive shall also be entitled to receive benefits consistent with those provided to other comparable executives within the Firstbank organization, including, but not limited to, health insurance, 401(k) participation, and paid vacation.

    7.        Management Continuity Agreement. Simultaneously with the execution and delivery of this Agreement, Firstbank shall enter into a Management Continuity Agreement with Executive in the form attached as Appendix A to this Agreement, which shall be effective as of the Effective Time of the Merger and which shall provide Executive with the benefits described in that Management Continuity Agreement. For a period of two years after the Effective Time of the Merger, the provisions of Section 11(b) and 11(c) of this Agreement shall supersede any conflicting provisions in the Management Continuity Agreement. Beginning two years after the Effective Time of the Merger, the provisions of Section 7 (Noncompetition) of the Management Continuity Agreement shall be in full force and effect.

    8.        Term of Employment. Executive’s employment shall be “at will” and may be terminated by the Bank or by Executive at any time, with our without Cause.

    9.        Consulting Agreement. In consideration of Executive’s post-employment commitments in Section 11 of this Agreement, if Executive’s employment is terminated by the Bank without Cause or if Executive terminates his employment for Good Reason, then the Bank shall retain Executive as a consultant (with independent contractor status) for the period from the date of termination of employment through that date which is three (3) years after the effective date of the Merger (the “Consulting Period”). During the Consulting Period Executive will make himself available as a part-time consultant, as requested, with reasonable accommodation for other time commitments, including other employment. The compensation for the consulting services will be Fifty Thousand Dollars ($50,000) per year, payable in monthly installments, plus the provision of health insurance benefits to Consultant and his dependents consistent with the health insurance benefits provided to Executive and his dependents during his employment, with COBRA rights to apply beginning at the end of the Consulting Period.

2

        The Consulting Period will not apply and no consulting payments shall be paid if Executive voluntarily terminates his employment without Good Reason. For purposes of this Agreement, “Good Reason” shall mean only the following, in each case which is not cured within twenty (20) days after written notice has been provided by Executive to the Bank and to Firstbank:

    (i)        A reduction in Executive’s Base Salary;

    (ii)        A demotion of Executive or a material reduction of Executive’s duties hereunder;

    (iii)        Requiring Executive to be based in an area other than in the geographic area in which the Bank conducts material business; or

    (iv)        A material breach of this Agreement by Firstbank.

        For the avoidance of doubt, Good Reason shall not include the elimination of Executive’s position as President and Chief Executive officer of the Bank as a result of consolidation of the Bank, provided that Executive is provided other reasonably suitable executive duties as determined by Firstbank.

        The Consulting Period will not apply and no consulting payment shall be paid if the Bank terminates Executive’s employment for Cause. For purposes of this Agreement, for “Cause” shall mean termination for only the following reasons, in each case which is not cured within twenty (20) days after written notice has been provided to Executive:

    (i)        Personal dishonesty materially affecting Firstbank or any of its Affiliates;

    (ii)        Willful material misconduct;

    (iii)        Willful breach of a fiduciary duty involving personal profit;

    (iv)        Intentional failure to perform stated duties called for by this Agreement;

    (v)        Willful violation of any material law, rule, or regulation relating to the operation of Firstbank or any of its Affiliates;

    (vi)        The order of any court or supervising agency with jurisdiction over the affairs of Firstbank or any of its Affiliates; or

3

    (vii)        Executive’s material violation of any material provision of this Agreement or willful material violation of any policy of Firstbank.

    10.        Death. In the event of the death of Executive during the term of this Agreement, Executive’s estate shall be entitled to receive the Cash Payment under Section 3 (if not already paid), the salary due Executive through the last day of the calendar month in which his death shall have occurred plus such other benefits as shall have accrued under this Agreement.

    11.        Confidentiality, Noncompetition, Nonsolicitation, Etc.

        Executive acknowledges that (i) Firstbank’s business is intensely competitive and that Executive’s employment by Firstbank requires that Executive have access to and knowledge of confidential information of Firstbank, including, but not limited to, the identity of Firstbank’s customers, the kinds of services provided by Firstbank to customers and offered to be performed for potential customers, the service needs of actual or prospective customers, product and service pricing information, marketing and business development strategies, Firstbank’s and customers’ financial information, computer software applications and other programs, personnel information, and other trade secrets (“Confidential Information”); (ii) the direct and indirect disclosure of any such Confidential Information to existing or potential competitors of Firstbank would place Firstbank at a competitive disadvantage and would cause damage, monetary or otherwise, to Firstbank’s business; and (iii) the engaging by Executive in any of the activities prohibited by this Section 11 may constitute improper appropriation and/or use of such Confidential Information. Executive expressly acknowledges the trade secret status of the Confidential Information and that the Confidential Information constitutes a protectable business interest of Firstbank. Accordingly, Firstbank and Executive agree as follows:

    (a)        For purposes of this Section 11, Firstbank shall be construed to include Firstbank and all its Affiliates, including the Bank.

    (b)        During the term of this Agreement and at all times after the voluntary or involuntary termination of Executive’s employment, Executive shall not, directly or indirectly, whether individually, as a director, stockholder, owner, partner, Executive, principal, or agent of any business, or in any other capacity, make known, disclose, furnish, make available, or utilize any of the Confidential Information, other than in the proper performance of the duties contemplated herein, or as required by a court of competent jurisdiction or other administrative or legislative body; provided that prior to disclosing any of the Confidential Information to a court or other administrative or legislative body, Executive shall promptly notify Firstbank so that Firstbank may seek a protective order or other appropriate remedy. Executive agrees to return all Confidential Information, including all photocopies, extracts, and summaries thereof, and such information stored electronically on tapes, computer discs, or in any other manner to Firstbank upon termination of his employment for any reason.

4

    (c)        If Executive’s employment is terminated (by either party, for any reason) before the second anniversary of the Effective Time of the Merger, then, until the second anniversary of the Effective Time off the Merger, Executive will not consult with, advise, manage, operate, control or be employed in any capacity by any business enterprise competing with Firstbank, or one of its subsidiaries, in any aspect of business actively being engaged in by Firstbank or one of its subsidiaries as of the date of termination. This non-competition restriction shall extend to Kent County and Ionia County and all geographical areas defined by a twenty-five (25) mile radius from the location of Firstbank’s home office and the home offices of all subsidiaries of Firstbank that exist as of the date of termination. Employment by the Executive for a banking institution or similar business that happens to maintain a branch office within the restricted territory shall not be deemed to be a violation of this non-competition provision so long as the location of the Executive’s personal office, and the territory or business locations being served, supervised or managed by the Executive in said new employment, are not located within the restricted area and so long as Executive does not directly or indirectly solicit or attempt to cause individuals or business entities that are customers of Firstbank to change or modify their banking or business relationships with Firstbank in any manner. This Section 11(c) will not apply to any time period after the second anniversary of the Effective Time of the Merger.

    (d)        During the term of his employment pursuant to this Agreement, and for two years following any termination of such employment which occurs within two years after the Effective Time of the Merger, Executive shall not, directly or indirectly, knowingly solicit, employ, or induce employees or customers of the Bank or of Firstbank to leave the employ of Firstbank or to transfer some or all of their business from Firstbank. This Section 11(d) will not apply if the termination of Executive’s employment occurs more than two years after the Effective Time of the Merger.

    (e)        Executive acknowledges that Firstbank would not be adequately compensated by damages in an action at law as a result of a material breach of this Agreement and that a material breach or threatened breach by him of any of the provisions contained in this Section 11 would cause Firstbank irreparable injury. Executive therefore agrees that Firstbank shall be entitled, in addition to any other right or remedy, to go to court to obtain a temporary, preliminary, or permanent injunction and monetary damages.

    (f)        Executive acknowledges and agrees that due to the uniqueness of his services and confidential nature of the information he will possess, the covenants set forth herein are reasonable and necessary for the protection of the business and goodwill of Firstbank. Executive acknowledges that the existence of any claim or cause of action against Firstbank by Executive, whether predicated upon this Agreement or otherwise, shall not constitute a defense to the enforcement by Firstbank of the restrictions and provisions contained in this Agreement.

5

    12.        Survival. If Executive’s employment is terminated during the term of this Agreement, the noncompetition and nonsolicitation covenants, as each is described in Section 11, shall continue in full force and effect notwithstanding expiration of the term of this Agreement.

    13.        Affiliate Defined. For purposes of this Agreement, the term “Affiliate” means any corporation or other entity that controls, is controlled by, or is under common control with any of Firstbank, the Bank, or ICNB Financial Corporation, and includes, without limitation, any such entity and each of its subsidiaries.

    14.        No Assignments. This Agreement is personal to each of the parties hereto, and neither Firstbank nor Executive may assign or delegate any of the rights or obligations hereunder without first obtaining the written consent of the other party.

    15.        Other Contracts. As of the Effective Date, all other prior agreements regarding conditions of employment, whether written or oral, are hereby terminated and superseded by this Agreement, except as provided in Section 1 of this Agreement. This Agreement contains the entire understanding of the parties concerning Executive’s employment and supersedes all previous oral and written agreements.

    16.        Notices. Any notices under this Agreement shall be deemed given when in writing and delivered personally or sent by certified mail, postage prepaid, to the last known address of the party to whom notice is given. If sent by mail, notice shall be deemed given on the third day after mailing.

    17.        Amendments. No amendments or additions to this Agreement shall be binding unless in writing and signed by each of the parties.

    18.        Paragraph Headings. The paragraph headings used in this Agreement are included solely for convenience and shall not affect or be used in connection with the interpretation of this Agreement.

    19.        Severability. The provisions of this Agreement shall be deemed severable, and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. Moreover, if any provision contained in this Agreement shall be held to be excessively broad as to duration, activity, or subject, such provision shall be construed by limiting and reducing it so as to be enforceable to the maximum extent allowed by applicable law.

    20.        Arbitration. Except as stated in Section 11 of this Agreement, any dispute, controversy, or claim arising under or in connection with this Agreement shall be settled exclusively by arbitration, conducted in Grand Rapids, Michigan, before a panel of three arbitrators, in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrators’ award in any court having jurisdiction. Unless otherwise provided in the Rules of the American Arbitration Association, the arbitrators shall, in their award, allocate between the parties the arbitrators’ fees and expenses, in such proportions as the arbitrators deem just. Each party shall be responsible for their own attorney fees.

6

    21.        Governing Law. This Agreement shall be governed by the laws of the United States of America and the State of Michigan with venue and jurisdiction limited to the Circuit Court for Kent County, Michigan.

APPENDIX A

MANAGEMENT CONTINUITY AGREEMENT

        This Management Continuity Agreement (this “Agreement”) entered into this __________ day of __________, by and between FIRSTBANK CORPORATION, hereinafter referred to as “FIRSTBANK”, and ▇▇▇▇▇ ▇. FAST, hereinafter referred to as “EXECUTIVE”.

        WITNESSETH:

        WHEREAS, FIRSTBANK is a Michigan Banking Corporation with subsidiaries in Alma, Mt. Pleasant, West Branch, Lakeview and St. ▇▇▇▇▇ and,

        WHEREAS, EXECUTIVE is an executive officer of FIRSTBANK, or one of its subsidiaries, whose continued employment has been deemed to be beneficial to FIRSTBANK by its Board of Directors, and, WHEREAS, EXECUTIVE’s knowledge of the day to day operations of FIRSTBANK, or its subsidiaries, and the existing banking relationships with customers of FIRSTBANK is such that EXECUTIVE’s termination of employment with FIRSTBANK and commencement of employment with a direct competitor of FIRSTBANK could have severe detrimental effects upon the business successes of FIRSTBANK, and,

        WHEREAS, EXECUTIVE is knowledgeable of the continuing possibility that FIRSTBANK may at some time in the future be purchased, merged into, or acquired by another banking organization, and,

        WHEREAS, EXECUTIVE is aware that such a purchase, merger or acquisition of FIRSTBANK might thereafter jeopardize EXECUTIVE’s continued employment as a result of downsizing, consolidation, or differences in operational philosophies, and,

9

        WHEREAS, FIRSTBANK desires to enter into a non competition agreement with EXECUTIVE which, under certain terms and conditions, will prevent EXECUTIVE from leaving employment with FIRSTBANK and commencing employment with a competitor of FIRSTBANK, and,

        WHEREAS, EXECUTIVE is willing to enter into such a non competition agreement with FIRSTBANK in exchange for a guarantee from FIRSTBANK of certain severance benefits, in the event of the purchase, merger or acquisition of FIRSTBANK by banking another organization.

        IT IS HEREBY AGREED AS FOLLOWS:

1. The initial term of this agreement shall be for a period commencing the date the agreement was entered into, and continuing until either party gives the required notice in writing that the agreement is to be terminated. This notice must be given at least two years prior to the anniversary date of this agreement when termination is to be effective. It is the intention of this paragraph that the terms of this agreement will remain in effect until notice of termination is given by either party at least two (2) years prior to the anniversary date of this agreement upon which termination of the agreement shall become effective.

2. EXECUTIVE’s rights for severance benefits established hereunder shall be applicable only if a CHANGE OF CONTROL occurs during the time this agreement remains in effect. A CHANGE OF CONTROL shall be defined as a purchase, merger, buy out, consolidation or other reorganization under the terms of which more than 50 percent of the combined voting power of the outstanding stock of FIRSTBANK becomes held by any group of less than ten (10) individuals, a banking entity, a trust, a corporation, an LLC, a joint venture, or any other business entity.

10

3. In the event a CHANGE OF CONTROL occurs, then if EXECUTIVE’s employment is involuntary terminated for any reason other than for CAUSE within six (6) months before, or two (2) years after the date of the CHANGE OF CONTROL, EXECUTIVE shall be entitled to the severance benefits set forth in paragraph 4. In addition, if a CHANGE OF CONTROL occurs, and the terms or conditions of EXECUTIVE’s employment “substantially change” during a time period defined as commencing six (6) months prior to the effective date of the CHANGE OF CONTROL and ending two (2) years after the effective date of the CHANGE OF CONTROL, then if EXECUTIVE elects to voluntarily terminate employment and said voluntary termination occurs within one (1) year of the occurrence of the “substantial change”, EXECUTIVE shall be entitled to severance benefits set forth in paragraph 4. If EXECUTIVE’s employment is terminated, or is in the process of being terminated, at any time for CAUSE (as that term is defined in paragraph 5 below) EXECUTIVE shall not under any circumstances be entitled to any of the severance benefits set forth in paragraph 4. A “substantial change” in EXECUTIVE’s employment shall be deemed to have occurred if any of the following occur:

a. EXECUTIVE’s employment is involuntarily terminated without CAUSE.

b. EXECUTIVE is assigned duties which result in a significant reduction or material change in EXECUTIVE’s authority or responsibility.

11

c. EXECUTIVE’s total base salary is reduced or EXECUTIVE is given bonuses or salary increases in a manner that is substantially less than those provided to other executive officers of FIRSTBANK.

d. EXECUTIVE is relocated to a place in excess of 25 miles from the location where EXECUTIVE is based on the date of this agreement.

e. FIRSTBANK or its successor fails to provide EXECUTIVE with substantially the same fringe benefits as other executives in similar positions with FIRSTBANK or its successors.

4. If eligible under the terms established in paragraph 3 above, the EXECUTIVE shall receive the following severance benefits upon termination:

a. A lump sum cash amount equal to 150% EXECUTIVE’s annual base salary at the highest annual rate in effect during the 12 month period prior to the date of termination.

b. 150% of any incentive bonus that may have been earned to date of termination by EXECUTIVE. c. Continued health care coverage for a period of two (2) years that is equivalent to the best coverage available for EXECUTIVE during the 12 month period prior to termination.

d. Continued life, accidental death and dismemberment coverage for a period of two (2) years equivalent to the best coverage provided for EXECUTIVE during the 12 month period prior to termination.

12

e. Continued disability insurance coverage for a period of two (2) years equivalent to the best coverage available to EXECUTIVE during the 12 month period prior to termination.

5. Nothing in the agreement shall be deemed to establish any right to continued employment by EXECUTIVE, and severance benefits shall be payable to EXECUTIVE only if all of the specific circumstances provided for herein are met. In the event EXECUTIVE is terminated for CAUSE, EXECUTIVE shall not be entitled to receive the severance benefits provided for herein. The term CAUSE shall be defined to mean:

a. The willful commission by the EXECUTIVE of a criminal or other act that causes or is likely to cause substantial economic damage or substantial injury to the business reputation of FIRSTBANK, or one of its subsidiaries.

b. Commission by EXECUTIVE of an act of fraud in the performance of EXECUTIVE’s duties on behalf of FIRSTBANK or one of its subsidiaries.

c. The continuing willful failure of EXECUTIVE to perform the duties of such EXECUTIVE to FIRSTBANK, one of its subsidiaries, or its successors.

6. Maximum Payments. Notwithstanding any provision in this agreement to the contrary, if part or all of any amount to be paid to EXECUTIVE by FIRSTBANK under this agreement or otherwise constitute a ‘parachute payment” (or payments) under Section 280G or any other similar provision of the Internal Revenue Code of 1986, as amended (the “Code”), the following limitation shall apply:

13

If the aggregate present value of such parachute payments (the “Parachute Amount”) exceeds 2.99 times EXECUTIVE’s “base amount” as defined in Section 280G of the Code, the amount otherwise payable to or for the benefit of the EXECUTIVE subsequent to the termination of his employment, and taken into account in calculating the Parachute Amount (the “termination payment”), shall be reduced and/or delayed, as further described below, to the extent necessary so that the Parachute Amount is equal to 2.99 times the EXECUTIVE’s “base amount”.

Any determination or calculation described in this Paragraph 6 shall be made by FIRSTBANK’s independent accountants. Such determination, and any proposed reduction and/or delay in termination payments shall be furnished in writing promptly by the accountants to the EXECUTIVE. The EXECUTIVE may then elect, in their sole discretion, which and how much of any particular termination payment shall be reduced and/or delayed and shall advise FIRSTBANK in writing of their election, within thirty (30) days of the accountant’s determination, of the reduction or delay in termination payments. If no such election is made by the EXECUTIVE within such 30 days period, FIRSTBANK may elect which and how much of any termination payment shall be reduced and/or delayed and shall notify the EXECUTIVE promptly of such election. As promptly as practicable following such determination and the elections hereunder, FIRSTBANK shall pay to or distribute to or for the benefit of the EXECUTIVE such amounts as are then due to the EXECUTIVE.

Any disagreement regarding a reduction or delay in termination payments will be subject to arbitration under paragraph 9 of this agreement. Neither the EXECUTIVE’s designation of specific payments to be reduced or delayed, nor the EXECUTIVE’s acceptance of reduced or delayed payments, shall waive the EXECUTIVE’s right to contest such reduction or delay.

14

7. Non Competition. The EXECUTIVE acknowledges that he/she has had and by the nature of his/her employment will have access to privileged, confidential, and proprietary information concerning FIRSTBANK and its subsidiaries. Under all circumstances and regardless of the reason for, or date of, termination of EXECUTIVE’s employment, the EXECUTIVE will maintain the confidentiality of and will not disclose to anyone or any entity other than FIRSTBANK or its subsidiaries said information. In addition, if (1) EXECUTIVE’s employment is involuntarily terminated for CAUSE or if (2) EXECUTIVE voluntarily terminates employment at any time this agreement remains in effect, but when neither a CHANGE OF CONTROL nor a ‘substantial change” of EXECUTIVE’s employment have occurred, then EXECUTIVE may not for a period of two years after the effective date of termination of EXECUTIVE’s employment:

a. Consult with, advise, manage, operate, control or be employed in any capacity by any business enterprise competing with FIRSTBANK, or one of its subsidiaries, in any aspect of business actively being engaged in by FIRSTBANK or one of its subsidiaries as of the date of termination. This non-competition restriction shall extend to all geographical areas defined by a twenty-five (25) mile radius from the location of FIRSTBANK’s home office and the home offices of all subsidiaries of FIRSTBANK that exist as of the date of termination. Employment by the EXECUTIVE for a banking institution or similar business that happens to maintain a branch office within the restricted territory shall not be deemed to be a violation of this non-competition provision so long as the location of the EXECUTIVE’s personal office, and the territory or business locations being served, supervised or managed by the EXECUTIVE in said new employment, are not located within the restricted area and so long as EXECUTIVE does not directly or indirectly solicit or attempt to cause individuals or business entities that are customers of FIRSTBANK to change or modify their banking or business relationships with FIRSTBANK in any manner.

15

b. Irrespective of the arbitration provisions of paragraph 9, the parties to this agreement stipulate the Gratiot County, Michigan, shall be the venue for resolution of disputes over the provisions of this paragraph 7. Likewise, the non-competition provisions of this paragraph may be enforced through injunctive relief issued by the Circuit Court of Gratiot County, Michigan.

It is understood that the non competition provisions of this agreement are NOT meant to be effective if either EXECUTIVE’s position is involuntarily terminated without CAUSE or if EXECUTIVE voluntarily terminates employment with one (1) year after both a CHANGE OF CONTROL has occurred and EXECUTIVE’s position has been “substantially changed” as defined in paragraph 3.

8. Withholding of Taxes. FIRSTBANK may withhold from any amounts payable under this agreement all federal, state, city, or other taxes as required by law.

9. Successors: Binding Agreements. This Agreement shall inure to the benefit of and be enforceable by EXECUTIVE’s personal and legal representatives, executors, administrators, successors, heirs, distributes, devisees and legatees. EXECUTIVE’s rights and benefits under this Agreement may not be assigned, except that if EXECUTIVE dies while benefits are being paid hereunder, any amount that would still be payable to EXECUTIVE hereunder if EXECUTIVE had continued to live, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement, to the beneficiaries designated by the EXECUTIVE to receive benefits under this Agreement in a writing on file the FIRSTBANK at the time of EXECUTIVE’s death or, if there has been no such beneficiary named, to EXECUTIVE’s estate. FIRSTBANK will require any successor (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of the business and/or assets of FIRSTBANK (or of any division or subsidiary thereof employing EXECUTIVE) to expressly assume and agree to perform this Agreement in the same manner and to the same extent that FIRSTBANK would be required to perform if no such succession had taken place. Failure of FIRSTBANK to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle EXECUTIVE to compensation from FIRSTBANK in the same manner and on the same terms to which EXECUTIVE would be entitled hereunder if EXECUTIVE had been involuntarily terminated without CAUSE following a CHANGE OF CONTROL.

16

10. Representations. As an inducement to FIRSTBANK to enter into and perform under the Agreement, EXECUTIVE represents and warrants to FIRSTBANK that to his/her knowledge all parts of this Agreement and the non-competition restrictions imposed upon EXECUTIVE by this Agreement are entered into to protect FIRSTBANK and are reasonable and necessary under the circumstances and are believed by EXECUTIVE to be so.

11. Notice. For the purpose of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States registered mail, return receipt requested, postage prepaid, addressed to the respective set forth on the first page of this Agreement, or at such other addresses as the parties may designate in writing.

17

12. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification, or discharge is agreed to in writing and signed by EXECUTIVE and such officer as may be specifically designated by the Board of Directors of FIRSTBANK. The validity, interpretation, construction, and performance of this Agreement shall be governed by the laws of the State of Michigan.

13. Employment Rights. This Agreement shall not confer upon EXECUTIVE any right to continue in the employ of FIRSTBANK or its subsidiaries and shall not in any way affect the right of FIRSTBANK or its subsidiaries to dismiss or otherwise terminate EXECUTIVE’s employment at any time with or without cause. ANY AND ALL FINANCIAL BENEFITS PROVIDED TO EXECUTIVE HEREIN ARE PAYABLE ONLY IN THE EVENT OF A CHANGE OF CONTROL AS THAT TERM IN DEFINED HEREIN.

14. No Vested Interest. Neither EXECUTIVE nor EXECUTIVE’s beneficiary shall have any right, title, or interest in any benefit under this Agreement prior to the occurrence of the right to the payment thereof, or in any property of FIRSTBANK or its subsidiaries or affiliates.
