**Item 1.01 Entry into a Material Definitive Agreement.**

On June 11, 2026, Isabella Bank Corporation, a Michigan corporation ("Isabella"), 401 Merger Sub, Inc., a Michigan corporation and a wholly owned subsidiary of Isabella ("Merger Sub"), and Grand River Commerce, Inc., a Michigan corporation ("Grand River"), entered into an Agreement and Plan of Merger (the "Merger Agreement"). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into Grand River, with Grand River as the surviving entity (the "Merger"), and immediately following the Merger, Grand River will merge with and into Isabella, with Isabella as the surviving entity (the "Second Step Merger"). The Merger Agreement further provides that immediately following the Second Step Merger, Grand River Bank, a Michigan state-chartered member bank and wholly owned subsidiary of Grand River, will merge with and into Isabella Bank, a Michigan state-chartered member bank and wholly owned subsidiary of Isabella, with Isabella Bank as the surviving bank (the "Bank Merger" and, together with the Merger and the Second Step Merger, the "Transaction"). The Merger Agreement was unanimously approved by the boards of directors of each of Isabella and Grand River.

***Merger Consideration***

Upon the terms and subject to the conditions of the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each voting and non-voting share of common stock of Grand River ("Grand River Common Stock") issued and outstanding immediately prior to the Effective Time, other than certain shares held by Grand River or Isabella or dissenting shares, will be converted into the right to receive, at the election of the holder thereof, and subject to adjustment and proration, as applicable, (i) an amount of cash equal to the quotient of (A) $18,262,391 (the "Aggregate Cash Consideration"), divided by (B) the product obtained by multiplying (x) the number of shares of Grand River Common Stock issued and outstanding as of the Effective Time by (y) 0.35 (the "Cash Conversion Number"), rounded to the nearest cent (the "Per Share Cash Consideration"), or (ii) the number of shares of Isabella common stock, no par value ("Isabella Common Stock"), multiplied by the Exchange Ratio (as defined below).

The Exchange Ratio is defined in the Merger Agreement as a number, as adjusted, of shares of Isabella Common Stock equal to the quotient of (A) 839,003 shares of Isabella Common Stock, divided by (B) the difference of (1) the aggregate number of shares of Grand River Common Stock issued and outstanding immediately prior to the Effective Time, other than certain shares held by Grand River or Isabella or dissenting shares, minus (2) the Cash Conversion Number, rounded to the nearest ten thousandth (the "Per Share Stock Consideration"). The Per Share Cash Consideration and/or the Per Share Stock Consideration are sometimes referred to herein collectively as the "Merger Consideration."

The Aggregate Cash Consideration is subject to reduction in the event that Grand River does not deliver at least $45.7 million of total shareholders' equity as determined in accordance with GAAP, less certain merger costs and reflecting other specified items described in the Merger Agreement.

Merger Consideration elections by Grand River shareholders will be subject to proration procedures whereby 65% of the shares of Grand River Common Stock will be exchanged for the Per Share Stock Consideration and 35% of the shares of Grand River common stock will be exchanged for the Per Share Cash Consideration. Based on the assumption of 9,122,073 shares of Grand River Common Stock issued and outstanding as of the Effective Time, the Per Share Cash Consideration to be paid is estimated to be approximately $5.72 and the Exchange Ratio is estimated to be approximately 0.1415.

Holders of Grand River Common Stock will receive cash in lieu of fractional shares.

***Treatment of Grand River's Equity Awards***

Upon the terms and subject to the conditions of the Merger Agreement, at the Effective Time, each stock option in respect of shares of Grand River Common Stock (each such stock option, a "Grand River Stock Option") granted under Grand River's equity incentive plans (the "Grand River Stock Plans") that is outstanding immediately prior to the Effective Time

will be cancelled and automatically converted into the right to receive a cash payment equal to (i) the number of shares of Grand River Common Stock subject to such Grand River Stock Option at the Effective Time, multiplied by (ii) the amount by which the Per Share Cash Consideration exceeds the per share exercise price of such Grand River Stock Option, less applicable taxes and tax withholdings and without interest. Notwithstanding the foregoing, if the per share exercise price for a Grand River Stock Option immediately prior to the Effective Time is equal to or in excess of the Per Share Cash Consideration, such Grand River Stock Option will be cancelled at the Effective Time in exchange for no consideration.

Upon the terms and subject to the conditions of the Merger Agreement, each restricted share of Grand River Common Stock granted under the Grand River Stock Plans that is outstanding and unvested immediately prior to the Effective Time (each such restricted share, a "Grand River Restricted Stock Award"), shall fully vest and shall have the treatment set forth in the Merger Agreement applicable to shares of Grand River Common Stock.

------

***Certain Other Terms and Conditions of the Merger Agreement***

The Merger Agreement contains customary representations and warranties from both Isabella and Grand River, and each party has agreed to customary covenants, including, among others, covenants relating to (i) the conduct of its business during the interim period between the execution of the Merger Agreement and the Effective Time, (ii) in the case of Grand River, its obligation to call a meeting of its shareholders to approve the Merger Agreement, and, subject to certain exceptions, the obligation of its board of directors to recommend that its shareholders approve the Merger Agreement, (iii) in the case of Grand River, its obligation to call a meeting of its shareholders to approve an amendment to Grand River's articles of incorporation ("Articles of Amendment") to create a class of non-voting common stock of Grand River to facilitate the conversion of Grand River's convertible subordinated debt due 2026 and the obligation of its board of directors to recommend that its shareholders approve the Articles of Amendment, and (iv) Grand River's non-solicitation obligations related to alternative acquisition proposals. Isabella and Grand River have also agreed to use their reasonable best efforts to prepare and file all applications, notices and other documents to obtain all necessary consents and approvals for consummation of the transactions contemplated by the Merger Agreement, including the Transaction.

The completion of the Transaction is subject to customary conditions, including (i) approval of the Merger Agreement by the requisite vote of the Grand River shareholders, (ii) authorization for listing on Nasdaq of the shares of Isabella Common Stock to be issued in the Merger, (iii) receipt of required regulatory approvals, including the approval of the Board of Governors of the Federal Reserve System and the Michigan Department of Insurance and Financial Services, Office of Banking, without the imposition of any condition or restriction that would be reasonably expected to have a material and adverse effect on the business, properties, assets, liabilities, results of operations or financial condition of Isabella and its subsidiaries, taken as a whole, after giving effect to the Merger, the Second Step Merger and the Bank Merger, (iv) effectiveness of the registration statement on Form S-4 for the Isabella Common Stock to be issued in the Merger, and (v) the absence of any order, injunction, decree or other legal restraint preventing the completion of the Merger, the Second Step Merger, the Bank Merger or any of the other transactions contemplated by the Merger Agreement or making the completion of the Merger, the Second Step Merger, the Bank Merger or any of the other transactions contemplated by the Merger Agreement illegal. Each party's obligation to complete the Transaction is also subject to certain additional customary conditions, including (a) subject to certain exceptions, the accuracy of the representations and warranties of the other party, (b) performance in all material respects by the other party of its obligations under the Merger Agreement, and (c) receipt by such party of an opinion from its counsel to the effect that the Merger and the Second Step Merger, taken together, will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

The Merger Agreement provides certain termination rights for both Isabella and Grand River and further provides that a termination fee of $2.18 million will be payable by Grand River upon termination of the Merger Agreement under certain circumstances.

The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of the parties to, the Merger Agreement; may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties (i) will not survive consummation of the Merger and (ii) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties' public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding Isabella or Grand River, their respective affiliates or their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding Isabella, Grand River, their respective affiliates or their respective businesses, the Merger Agreement, the Merger, the Second Step Merger and the Bank Merger that will be contained in, or incorporated by reference into, the Registration Statement on Form S-4 that will include a proxy statement of Grand River and a prospectus of Isabella, as well as in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings that Isabella makes with the Securities and Exchange Commission ("SEC").

The foregoing description of the Merger Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Merger Agreement, which is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

***Voting Agreements***

Simultaneously with the execution of the Merger Agreement, Isabella entered into a voting agreement (a "Grand River Voting Agreement") with each of the directors and executive officers of Grand River. Each Grand River director and executive officer, as a shareholder party to a Grand River Voting Agreement, has agreed, among other things, to vote shares of Grand River Common

------

Stock owned by such shareholder, and over which such shareholder has the right to dispose of and has voting power, (i) in favor of the Merger Agreement and the other transactions contemplated by the Merger Agreement, including the Transaction, (ii) in favor of the Articles of Amendment, and (iii) against any competing acquisition proposal, any action, agreement transaction or proposal which could reasonably be expected to result in a breach of any representation, warranty, covenant, agreement or other obligation of Grand River in the Merger Agreement in any material respect, or other action that is intended or would reasonably be expected to prevent, impede, interfere with, delay, postpone or discourage any of the transactions contemplated by the Merger Agreement. The Grand River Voting Agreements will terminate in certain circumstances, including upon consummation of the Merger or the termination of the Merger Agreement in accordance with its terms.

The foregoing description of the Grand River Voting Agreements does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Grand River Voting Agreements, the form of which is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

**Forward-Looking Statements**

This Current Report on Form 8-K and the exhibits filed herewith contain "forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as "may," "believe," "expect," "anticipate," "intend," "should," "plan," "estimate," "predict," "continue" and "potential" or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the proposed merger with Grand River, the expected returns and other benefits of the proposed merger to shareholders, expected improvement in operating efficiency resulting from the proposed merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the expected impact on and timing of the recovery of the impact on tangible book value, and the expected effect of the proposed merger on Isabella's capital ratios. Forward-looking statements represent management's beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements.

Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the proposed merger may not be realized or take longer than anticipated to be realized, (2) disruption from the proposed merger with customers, suppliers, employee or other business partners, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, (4) the risk of successful integration of Grand River's business into Isabella, (5) the failure to obtain the necessary approval by the shareholders of Grand River, (6) the amount of the costs, fees, expenses and charges related to the proposed merger, (7) the ability of the parties to obtain required governmental approvals of the proposed merger, (8) reputational risk and the reaction of each of the companies' customers, suppliers, employees or other business partners to the merger, (9) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing of the proposed merger, (10) the risk that the integration of Grand River's operations into the operations of Isabella will be materially delayed or will be more costly or difficult than expected, (11) the possibility that the proposed merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by Isabella's issuance of additional shares of its common stock in the merger transaction, and (13) general competitive, economic, political and market conditions. Other relevant risk factors may be detailed from time to time in Isabella's press releases and filings with the Securities and Exchange Commission (the "SEC"). Consequently, no forward-looking statement can be guaranteed. Neither Isabella nor Grand River undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For any forward-looking statements made in this communication or any related documents, Isabella and Grand River claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Each share of Isabella Common Stock that is issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding following the Effective Time and shall be unchanged by the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)All shares of Grand River Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares and shares of Grand River Common Stock to be cancelled pursuant to <u>Section 2.1(b)</u>) shall become and be converted into the right to receive, without interest, at the election of the holder thereof and in accordance with the procedures set forth in <u>Sections 2.4</u> and subject to <u>Section 2.2</u> and <u>Section 2.5</u>, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.for each share of Grand River Common Stock with respect to which an election to receive cash has been effectively made and not revoked or lost, pursuant to <u>Section 2.4</u> (a "<u>Cash Election</u>"), subject to adjustment, the right to receive in cash from Isabella, without interest, of an amount of cash equal to the quotient of (A) $18,262,391, (as adjusted, the "<u>Aggregate Cash Consideration</u>"), divided by (B) the Cash Conversion Number, rounded to the nearest cent (such amount, the "<u>Per Share Cash Consideration</u>") (collectively, "<u>Cash Election Shares</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.for each share of Grand River Common Stock with respect to which an election to receive Isabella Common Stock has been effectively made and not revoked or lost, pursuant to <u>Section 2.4</u> (a "<u>Stock Election</u>"), subject to adjustment, the right to receive from Isabella the number of shares of Isabella Common Stock equal to the Exchange Ratio (the "<u>Per Share Stock Consideration</u>") (collectively, the "<u>Stock Election Shares</u>"); and

------

For purposes of this Agreement: (x) "<u>Exchange Ratio</u>" means a number, as adjusted, of shares of Isabella Common Stock equal to the quotient of (A) the Aggregate Stock Consideration divided by (B) the difference of (1) the aggregate number of shares of Grand River Common Stock issued and outstanding immediately prior to the Effective Time (excluding Dissenting Shares and shares of Grand River Common Stock to be cancelled as provided in Section 2.1(b)) minus (2) the Cash Conversion Number, rounded to the nearest ten thousandth; (y) "<u>Aggregate Stock Consideration</u>" means 839,003 shares of Isabella Common Stock, subject to appropriate adjustment (without duplication based on the same adjustment being provided elsewhere in this Agreement) for any stock split, reverse stock split, recapitalization, reclassification or similar transaction with respect to the then outstanding shares of Isabella Common Stock declared or effected after the date of this Agreement and prior to the Closing Date; and (z) the Per Share Cash Consideration and/or the Per Share Stock Consideration are sometimes referred to herein collectively as the "<u>Merger Consideration</u>."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2<u>Proration</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Notwithstanding any other provision contained in this Agreement, the number of shares of Grand River Common Stock to be converted into the Per Share Cash Consideration (the "<u>Cash Conversion Number</u>") shall be equal to the product obtained by multiplying (x) the number of shares of Grand River Common Stock issued and outstanding as of the Effective Time (excluding Dissenting Shares and shares of Grand River Common Stock to be canceled as provided in <u>Section 2.1(b)</u>) by (y) 0.35.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Within five (5) Business Days after the Effective Time, Isabella shall cause the Exchange Agent (as defined below) to effect the allocation among holders of Grand River Common Stock of rights to receive the Per Share Cash Consideration and the Per Share Stock Consideration as follows:

------

of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the Cash Election Shares exceed (2) the Cash Conversion Number and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder's Cash Election Shares being converted into the right to receive the Per Share Cash Consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)If the number of Cash Election Shares is less than the Cash Conversion Number, then:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.the Non-Election Shares of each holder thereof shall be converted into the right to receive the Per Share Cash Consideration in respect of that number of Non-Election Shares (rounded to the nearest whole share) equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the Cash Conversion Number exceeds (2) the Cash Election Shares and the denominator of which is the sum of (I) the total number of Stock Election Shares plus (II) the total number of Non-Election Shares, with the remaining number of such holder's Non-Election Shares being converted into the right to receive the Per Share Stock Consideration.

All shares of Grand River Common Stock, when converted as provided in <u>Section 2.1(a)(ii)</u>, shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each certificate previously evidencing such shares of Grand River Common Stock (each, a "<u>Certificate</u>", it being understood that any reference herein to "Certificate" shall be deemed to include reference to book-entry account statements relating to the ownership of shares of Grand River Common Stock) (other than Certificates with respect to Dissenting Shares) shall thereafter represent only the right to receive for each such share of Grand River Common Stock, the Merger Consideration and, if applicable, any cash in lieu of fractional shares of Isabella Common Stock in accordance with <u>Section 2.4(l)</u>. At the Effective Time, holders of the Grand River Common Stock shall cease to be, and shall have no rights as, shareholders of Grand River other than the right to receive the Merger Consideration and cash in lieu of fractional shares of Isabella Common Stock as provided under this <u>Article II</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4<u>Election and Exchange Procedures</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Isabella shall prepare a form reasonably acceptable to Grand River (the "<u>Form of Election</u>") which shall be mailed to Grand River's shareholders of record so as to permit Grand River shareholders to exercise their right to make an Election prior to the Election Deadline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Form of Election shall be mailed to each holder of Grand River Common Stock not less than thirty (30) calendar days prior to the anticipated Effective Time or on such date as Grand River and Isabella shall mutually agree (the "<u>Mailing Date</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Any Election shall have been made properly only if the Person authorized to receive Elections and to act as Exchange Agent under this Agreement, which Person shall be designated by Isabella and reasonably acceptable to Grand River (the "<u>Exchange Agent</u>"), pursuant to an agreement entered into prior to Closing shall have received, by 5:00 p.m. local time in the city in which the principal office of such Exchange Agent is located, on the date that is the twenty-fifth (25<sup>th</sup>) calendar day following the Mailing Date (the "<u>Election Deadline</u>"), a Form of Election properly completed and signed accompanied by the Certificates representing Grand River Common Stock as to which such Form of Election is being made or by an appropriate guarantee of delivery of such Certificates, as set forth in the Form of Election.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Any Grand River shareholder may, at any time prior to the Election Deadline, change or revoke their Election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed revised Form of Election. If Isabella, after consultation with the Exchange Agent, shall determine in its reasonable discretion that any Election is not properly made with respect to any shares of Grand River Common Stock, such Election shall be deemed to be not in effect, and the shares of Grand River Common Stock covered by such Election shall, for purposes hereof, be deemed to be Non-Election Shares, unless a proper Election is thereafter timely made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)All Elections shall be revoked automatically if the Exchange Agent is notified in writing by Isabella or Grand River that this Agreement has been terminated in accordance with <u>Article VII</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name a Certificate surrendered pursuant to <u>Section 2.4(i)</u> is registered, it shall be a condition to such payment that such Certificate shall be properly endorsed or otherwise be in proper form for transfer, as applicable, and the Person requesting such payment shall inform the Exchange Agent, pursuant to an agreement entered into prior to Closing, whether any transfer or other similar Taxes are required as a result of such payment to a Person other than the registered holder of such Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Taxes are not payable. If such transfer or other similar Taxes are payable pursuant to the preceding sentence, then the Exchange Agent shall withhold and deduct from the Merger Consideration (including cash in lieu of fractional shares of Isabella Common Stock) otherwise payable pursuant to this Agreement to the designated Person other than the registered holder such amounts as the Exchange Agent determines is necessary based on the information supplied by the registered holder. The Exchange Agent (or, subsequent to the twelve-month anniversary of the Effective Time, Isabella) shall be entitled to deduct and withhold from the Merger Consideration (including cash in lieu of fractional shares of Isabella Common Stock) otherwise payable pursuant to this Agreement to any holder of Grand River Common Stock such amounts as the Exchange Agent or Isabella, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent that any amounts are withheld by the Exchange Agent or Isabella, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Grand River Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or Isabella, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)At least one (1) business day prior to the Effective Time, Isabella shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Grand River Common Stock pursuant to this Article II (i) certificates, or at Isabella's option, evidence of shares in book-entry form, representing the shares of Isabella Common Stock, sufficient to pay the Aggregate Stock Consideration required pursuant to this <u>Article II</u>, and (ii) an aggregate amount of cash sufficient to pay the Aggregate Cash Consideration and the estimated amount of cash to be paid in lieu of fractional shares of Isabella Common Stock, each to be given to the holders of Grand River Common Stock in exchange for Certificates pursuant to this <u>Article II</u>. Until the twelve (12) month anniversary of the Effective Time, Isabella shall make available on a timely basis or cause to be made available to the Exchange Agent the following: (i) certificates, or at Isabella's option, evidence of shares in book-entry form, representing the

------

shares of Isabella Common Stock, sufficient to pay the Aggregate Stock Consideration required pursuant to this <u>Article II</u>, and (ii) an aggregate amount of cash sufficient to pay the Aggregate Cash Consideration and the estimated amount of cash to be paid in lieu of fractional shares of Isabella Common Stock, each to be given to the holders of Grand River Common Stock in exchange for Certificates pursuant to this <u>Article II</u>. Upon such twelve (12) month anniversary, any such cash or certificates remaining in the possession of the Exchange Agent, together with any earnings in respect thereof, shall be delivered to Isabella. Any holder of Certificates who has not theretofore exchanged his or her Certificates or for the Merger Consideration pursuant to this <u>Article II</u> who has not theretofore submitted a letter of transmittal, if required, shall thereafter be entitled to look exclusively to Isabella, and only as a general creditor thereof, for the Merger Consideration, as applicable, to which he or she may be entitled upon exchange of such Certificates pursuant to this <u>Article II</u>. Isabella and the Exchange Agent shall be entitled to rely upon the stock transfer books of Grand River to establish the identity of those Persons entitled to receive the Merger Consideration, which books shall be conclusive with respect thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Promptly after the Effective Time, but in no event later than five (5) Business Days thereafter, Isabella shall cause the Exchange Agent to mail or deliver to each Person who did not surrender, or who improperly surrendered, such shareholder's Certificates (other than Certificates with respect to Dissenting Shares) to the Exchange Agent and who was, immediately prior to the Effective Time, a holder of record of Grand River Common Stock a notice advising such holders of the effectiveness of the Merger, including a form of letter of transmittal in a form reasonably satisfactory to Isabella and Grand River containing instructions for use in effecting the surrender of Certificates in exchange for the Merger Consideration which shall specify that delivery shall be effected, and risk of loss and title to Certificates shall pass, only upon with respect to shares evidenced by Certificates, proper delivery of such Certificates to the Exchange Agent, proper delivery of the Certificates and the transmittal materials, duly, completely and validly executed in accordance with the instructions thereto. Upon surrender to the Exchange Agent of a Certificate for cancellation together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall promptly be provided in exchange therefor, but in no event later than five (5) Business Days after due surrender, (x) a certificate, or at the election of Isabella, a statement reflecting shares issued in book-entry form, representing the number of whole shares of Isabella Common Stock that such holder is entitled pursuant to this <u>Article II</u>, and (y) a check in the amount equal to the sum of (A) the cash portion of the Merger Consideration that such holder has the right to receive in respect of such Certificate surrendered pursuant to this <u>Article II</u>, (B) any cash in lieu of fractional shares pursuant to <u>Section 2.4(l)</u> and (C) any dividends or other distributions that such holder is entitled pursuant to <u>Section 2.4(k)</u>, and the Certificate so surrendered shall forthwith be canceled. No interest shall accrue or be paid with respect to any property to be delivered upon surrender of Certificates**.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)In the event any Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate(s) to be lost, stolen or destroyed and, if required by Isabella or the Exchange Agent, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate(s), Isabella shall cause the Exchange Agent to issue the Merger Consideration deliverable, and any cash, unpaid dividends or other distributions that would be payable or deliverable, in respect of the shares of Grand River Common Stock represented by such lost, stolen or destroyed Certificates.

Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite Grand River Vote, Grand River receives an unsolicited bona fide written Acquisition Proposal that did not result from a breach of this <u>Section 6.12</u>, Grand River may, and may permit its Subsidiaries and its and its Subsidiaries' Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal but only to the extent that, prior to doing so, the Board of Directors of Grand River concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its outside financial advisors) that (A) such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal, and (B) failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; <u>provided</u>, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, Grand River shall have provided such information to Isabella and shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with Grand River.

------

Grand River shall use its reasonable best efforts to (x) enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof, and (y) within five (5) business days after the date hereof, request and confirm the return or destruction of any confidential information provided to any person (other than Isabella and its Representatives in their capacity as such) pursuant to any such agreement. As used in this Agreement, "<u>Acquisition Proposal</u>" means, other than the transactions contemplated by this Agreement, as it may be amended from time to time, any offer, proposal or inquiry relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of Grand River and its Subsidiaries or 25% or more of any class of equity or voting securities of Grand River or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Grand River, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning 25% or more of any class of equity or voting securities of Grand River or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Grand River, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Grand River or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Grand River. As used in this Agreement, "<u>Superior Proposal</u>" means any unsolicited bona fide written offer or proposal made by a third party to consummate an Acquisition Proposal that Grand River's Board of Directors determines in good faith (after receiving the advice of its outside counsel and, with respect to financial matters, its outside financial advisors) (x) would, if consummated, result in the acquisition of all, but not less than all, of the issued and outstanding shares of Grand River's common stock or all, or substantially all, of the assets of Grand River, (y) would result in a transaction that (i) involves consideration to the holders of the shares of Grand River's common stock that is, after accounting for payment of the Termination Fee that may be required hereunder, more favorable, from a financial point of view, than the consideration to be paid to the holders of shares of Grand River's common stock pursuant to this Agreement, considering, among other things, the nature of the consideration being offered, and any material regulatory approvals or other risks associated with the timing of the proposed transaction beyond, or in addition to, those specifically contemplated hereby, and which proposal is not conditioned upon obtaining financing and (ii) is, in light of the other terms of such proposal, more favorable to the shareholders of Grand River than the Mergers and the other transactions contemplated by this Agreement, and (z) is reasonably likely to be completed on the terms proposed, in each case, taking into account all legal, financial, regulatory and other aspects of the Acquisition Proposal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of Grand River or shall have been made directly to the shareholders of Grand River generally or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the Grand River Meeting) an Acquisition Proposal, in each case with respect to Grand River and (A) (x) thereafter this Agreement is terminated by either Isabella or Grand River pursuant to <u>Section 8.1(c)</u> without the Requisite Grand River Vote having been obtained (and all other conditions set forth in <u>Sections 7.1</u> and <u>7.3</u> having been satisfied or were capable of being satisfied prior to such termination), or (y) thereafter this Agreement is terminated by Isabella pursuant to

------

<u>Section 8.1(d)</u> as a result of a willful breach of this Agreement by Grand River, or (z) this Agreement is terminated by either Isabella or Grand River pursuant to <u>Section 8.1(f)</u>, and (B) prior to the date that is twelve (12) months after the date of such termination, Grand River enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then Grand River shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay Isabella, by wire transfer of same day funds, a fee equal to $2.18 million (the "<u>Termination Fee</u>"); <u>provided</u>, that for purposes of this <u>Section 8.2(b)(i)</u>, all references in the definition of Acquisition Proposal to "25%" shall instead refer to "50%".

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

The undersigned shareholder (the "<u>Shareholder"</u>) of Grand River Commerce, Inc., a Michigan corporation ("<u>Grand River"</u>), in the Shareholder's capacity as a shareholder of Grand River, and not in his or her capacity as a director or officer of Grand River, as applicable, hereby acknowledges that Grand River, Isabella Bank Corporation, a Michigan corporation ("<u>Isabella"</u>), and Isabella Merger Sub, Inc., a Michigan corporation and a wholly owned subsidiary of Isabella ("<u>Merger Sub</u>"), have entered into an Agreement and Plan of Merger, dated as of the same date hereof (as amended or modified from time to time, the "<u>Merger Agreement"</u>), pursuant to which, among other things, Merger Sub will be merged with and into Grand River, with Grand River as the surviving corporation (the "<u>Interim</u> <u>Surviving Corporation"</u>) in such merger (the "<u>Merger"</u>) and, immediately following the Merger, the Interim Surviving Corporation will merge with and into Isabella, with Isabella as the surviving corporation of such Merger (the "<u>Second Step Merger"</u>, and together with the Merger, the "<u>Mergers"</u>). A copy of the Merger Agreement has been provided to the Shareholder.

For all purposes of this agreement, the Owned Shares will include any shares of Grand River Common Stock as to which the Shareholder acquires beneficial or record ownership after the date hereof. The Owned Shares are owned by the Shareholder free and clear of all encumbrances, voting arrangements and commitments of every kind, except as would not restrict the performance of the Shareholder's obligations or compliance with the restrictions under this agreement. The Shareholder does not beneficially own any shares of Grand River Common Stock other than the Owned Shares.

Additionally, if prior to the Effective Time, a proposal is brought by Grand River to shareholders of Grand River to amend Grand River's Articles of Incorporation for the purpose of creating a class of Grand River stock (the "Charter Amendment"), the Shareholder agrees that, at any such meeting or action of the shareholders of Grand River, including a written consent solicitation, the Shareholder will (a) appear at such meeting or otherwise cause the Owned Shares to be counted as present thereat for the purpose

Notwithstanding anything to the contrary in this agreement, the parties acknowledge that (x) this agreement is entered into by the Shareholder solely in his or her capacity as a holder of the Owned Shares and not in his or her capacity as a director and/or officer of Grand River or Grand River Bank, and that nothing in this agreement shall prevent the Shareholder from discharging his or her fiduciary duties as an executive officer or director of Grand River, as applicable, and (y) the taking of any actions (or failures to act) by any of the undersigned in such person's capacity as an executive officer or director of Grand River shall not be deemed to constitute a breach of this agreement, including without limitation, the taking of any action permitted by and in accordance with Section 6.4 or Section 6.12 of the Merger Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. *Transfer of Owned Shares and Grand River Common Stock*. From the date hereof until the Effective Time, the Shareholder agrees that he or she will not, without the prior written consent of Isabella, directly or indirectly, sell, offer for sale, transfer, pledge, assign, encumber or otherwise dispose of, or enter into any contract, agreement, option, commitment, derivative or other arrangement or understanding with respect to any sale, offer for sale, transfer, pledge, assignment, encumbrance or other disposition (each, a "Transfer") of any of the Owned Shares or the voting rights thereunder, other than (i) any Transfer made for *bona fide* estate planning purposes, (ii) any Transfer to an Affiliate of such Shareholder, or (iii) a Transfer solely in connection with the payment of the exercise price and/or the satisfaction of any tax withholding obligations arising from the exercise of any equity awards, stock options, warrants or the conversion of any convertible securities; *provided* that, in the case of the foregoing *subclauses (i)* and *(ii)* only, as a condition to such Transfer, such transferee agrees in writing to be bound by the applicable terms hereof and notice of such Transfer is provided to Isabella.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. *Further Assurances*.

<u>FORM OF VOTING AGREEMENT</u>

June 11, 2026

Grand River Commerce, Inc.

4471 Wilson Avenue SW

Grandville, MI 49418

<br>Ladies and Gentlemen:

The undersigned shareholder (the "<u>Shareholder"</u>) of Grand River Commerce, Inc., a Michigan corporation ("<u>Grand River"</u>), in the Shareholder's capacity as a shareholder of Grand River, and not in his or her capacity as a director or officer of Grand River, as applicable, hereby acknowledges that Grand River, Isabella Bank Corporation, a Michigan corporation ("<u>Isabella"</u>), and Isabella Merger Sub, Inc., a Michigan corporation and a wholly owned subsidiary of Isabella ("<u>Merger Sub</u>"), have entered into an Agreement and Plan of Merger, dated as of the same date hereof (as amended or modified from time to time, the "<u>Merger Agreement"</u>), pursuant to which, among other things, Merger Sub will be merged with and into Grand River, with Grand River as the surviving corporation (the "<u>Interim</u> <u>Surviving Corporation"</u>) in such merger (the "<u>Merger"</u>) and, immediately following the Merger, the Interim Surviving Corporation will merge with and into Isabella, with Isabella as the surviving corporation of such Merger (the "<u>Second Step Merger"</u>, and together with the Merger, the "<u>Mergers"</u>). A copy of the Merger Agreement has been provided to the Shareholder. Capitalized terms used but not defined herein are to be deemed to have the same meanings assigned to them in the Merger Agreement.

As an inducement to and condition of Isabella's willingness to enter into the Merger Agreement, the Shareholder hereby agrees, represents and warrants as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. *Owned Shares*. As of the date hereof, the Shareholder owns (of record or beneficially) and has the full power and authority to vote [●] shares of Grand River Common Stock (the "<u>Owned Shares"</u>). For all purposes of this agreement, the Owned Shares will include any shares of Grand River Common Stock as to which the Shareholder acquires beneficial or record ownership after the date hereof. The Owned Shares are owned by the Shareholder free and clear of all encumbrances, voting arrangements and commitments of every kind, except as would not restrict the performance of the Shareholder's obligations or compliance with the restrictions under this agreement. The Shareholder does not beneficially own any shares of Grand River Common Stock other than the Owned Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. *Agreement to Vote Owned Shares*. The Shareholder agrees that, at the Grand River Meeting or any other meeting or action of the shareholders of Grand River, including a written consent solicitation, the Shareholder will (a) appear at such meeting or otherwise cause the Owned Shares to be counted as present thereat for the purpose of establishing a quorum, (b) vote all of the Owned Shares (or otherwise provide a proxy, consent or voting instruction or direction) in favor of (i) approval of the Merger Agreement, the Mergers and any other matters required to be approved or adopted in order to effect the Mergers and the transactions contemplated by the Merger Agreement and (ii) the adjournment or postponement of Grand River Meeting, (c) not initiate any proxy solicitation or undertake any other efforts against the Merger Agreement, the Mergers or the transactions contemplated by the Merger Agreement, and (d) not vote the Owned Shares (or otherwise provide a proxy or consent) in favor of, or otherwise support, approval of any Acquisition Proposal with respect to Grand River or any action that is intended to, or could reasonably be expected to, impede, interfere with, or delay or otherwise adversely affect the Mergers or the transactions contemplated by the Merger Agreement. Additionally, if prior to the Effective Time, a proposal is brought by Grand River to shareholders of Grand River to amend Grand River's Articles of Incorporation for the purpose of creating a class of Grand River stock (the "Charter Amendment"), the Shareholder agrees that, at any such meeting or action of the shareholders of Grand River, including a written consent solicitation, the Shareholder will (a) appear at such meeting or otherwise cause the Owned Shares to be counted as present thereat for the purpose of establishing a quorum, (b) vote all of the Owned Shares (or otherwise provide a proxy, consent or voting instruction or direction) in favor of (i) approval of the Charter Amendment and (ii) the adjournment or postponement

------

of such meeting, (c) not initiate any proxy solicitation or undertake any other efforts against the Charter Amendment. Notwithstanding anything to the contrary in this agreement, the parties acknowledge that (x) this agreement is entered into by the Shareholder solely in his or her capacity as a holder of the Owned Shares and not in his or her capacity as a director and/or officer of Grand River or Grand River Bank, and that nothing in this agreement shall prevent the Shareholder from discharging his or her fiduciary duties as an executive officer or director of Grand River, as applicable, and (y) the taking of any actions (or failures to act) by any of the undersigned in such person's capacity as an executive officer or director of Grand River shall not be deemed to constitute a breach of this agreement, including without limitation, the taking of any action permitted by and in accordance with Section 6.4 or Section 6.12 of the Merger Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. *Transfer of Owned Shares and Grand River Common Stock*. From the date hereof until the Effective Time, the Shareholder agrees that he or she will not, without the prior written consent of Isabella, directly or indirectly, sell, offer for sale, transfer, pledge, assign, encumber or otherwise dispose of, or enter into any contract, agreement, option, commitment, derivative or other arrangement or understanding with respect to any sale, offer for sale, transfer, pledge, assignment, encumbrance or other disposition (each, a "Transfer") of any of the Owned Shares or the voting rights thereunder, other than (i) any Transfer made for *bona fide* estate planning purposes, (ii) any Transfer to an Affiliate of such Shareholder, or (iii) a Transfer solely in connection with the payment of the exercise price and/or the satisfaction of any tax withholding obligations arising from the exercise of any equity awards, stock options, warrants or the conversion of any convertible securities; *provided* that, in the case of the foregoing *subclauses (i)* and *(ii)* only, as a condition to such Transfer, such transferee agrees in writing to be bound by the applicable terms hereof and notice of such Transfer is provided to Isabella.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. *Further Assurances*. The Shareholder will take all reasonable actions and make all reasonable efforts, and will execute and deliver all such further agreements, documents, certificates, instruments, proxies and voting instructions as reasonably necessary, in order to fulfill his or her agreements and obligations contemplated hereby, including, without limitation, the agreement of the Shareholder to vote the Owned Shares in accordance with Section 2 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. *No Solicitation*.

Notwithstanding the foregoing, in the event Grand River is engaging in discussions or negotiations with a person making an Acquisition Proposal in accordance with Section 6.12 of the Merger Agreement with respect to such Acquisition Proposal, the Shareholder and his or her agents and representatives (including, without limitation, any investment banker, attorney or accountant retained by the Shareholder) shall be entitled to engage in any discussions or negotiations that Grand River is permitted to engage in pursuant to Section 6.12 of the Merger Agreement with respect to such Acquisition Proposal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. *Specific Performance*.

Each of the parties hereby further waives (a) any defense in any action for specific performance that a

------

remedy at law would be adequate and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. *Public Announcements*. The Shareholder agrees that no public release or announcement or statement concerning this agreement or concerning the transactions contemplated by the Merger Agreement shall be issued by the Shareholder without the prior written consent of Isabella (which consent shall not be unreasonably withheld, conditioned or delayed), except (i) as required by applicable law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the Shareholder is subject, in which case the Shareholder shall consult with Isabella about, and allow Isabella reasonable time to comment on, such release or announcement in advance of such issuance or (ii) for such releases, announcements or statements that are consistent with other such releases, announcements or statements made after the date of this agreement in compliance with this Section 7.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. *Electronic Transmission.* This agreement and any signed agreement or instrument entered into in connection with this agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by email delivery of a ".pdf" format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto shall raise the use of email delivery of a ".pdf" format data file to deliver a Grand River to this agreement or any amendment hereto or the fact that any Grand River or agreement or instrument was transmitted or communicated through the email delivery of a ".pdf" format data file as a defense to the formation of a contract and each party hereto forever waives any such defense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. *Amendment.* Subject to compliance with applicable law, this agreement may be amended by the parties hereto. This agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each of the parties hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17. *Extension; Waiver.* The Shareholder, with respect to Isabella, and Isabella, with respect to the Shareholder, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of Isabella (in the case of the Shareholder) or the Shareholder (in the case of Isabella), (b) waive any inaccuracies in the representations and warranties of Isabella (in the case of the Shareholder) or the Shareholder (in the case of Isabella) contained herein, and (c) waive compliance with any of the agreements or satisfaction of any conditions of Isabella (in the case of the Shareholder) or the Shareholder (in the case of Isabella) contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. *Interpretation.* The parties have participated jointly in negotiating and drafting this agreement. In the event that an ambiguity or a question of intent or interpretation arises, this agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this agreement. The headings contained in this agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this agreement. Whenever the words "include," "includes" or "including" are used in this agreement, they shall be deemed to be followed by the words "without limitation." This agreement shall not be interpreted or construed to require any person to take any action, or fail to take any action, if to do so would violate any applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19. *Entire Agreement.* This agreement (including the documents and the instruments referred to herein) constitutes the entire agreement among the parties and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof.

EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT: (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 20.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;21. *Assignment; Third-Party Beneficiaries.* Neither this agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties. Any purported assignment in contravention hereof shall be null and void.
