AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of August 23, 2016 (this “Agreement”), by and between First Defiance Financial Corp., an Ohio corporation (“First Defiance”), and Commercial Bancshares, Inc., an Ohio corporation (“Commercial Bancshares”).

WITNESSETH:

WHEREAS, the Boards of Directors of First Defiance and Commercial Bancshares have determined that it is in the best interests of their respective companies and their shareholders to consummate the strategic business combination transaction provided for herein, pursuant to which Commercial Bancshares will, subject to the terms and conditions set forth herein, merge with and into First Defiance (the “Merger”), so that First Defiance is the surviving company (hereinafter sometimes referred to in such capacity as the “Surviving Company”) in the Merger;

WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”) and this Agreement is intended to be and is adopted as a plan of reorganization within the meaning of Treasury Regulation Sections 1.368-2(g) and 1.368-3(a); and

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Ohio General Corporation Law (the “OGCL”), at the Effective Time, Commercial Bancshares will merge with and into First Defiance. First Defiance will be the Surviving Company in the Merger, and will continue its corporate existence under the laws of the State of Ohio. Upon consummation of the Merger, the separate corporate existence of Commercial Bancshares will terminate.

1.2 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place at a mutually agreeable time and place after the satisfaction or waiver (subject to applicable law) of the latest to occur of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof). The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

1.3 Effective Time. Subject to the terms and conditions of this Agreement, on or before the Closing Date, First Defiance will file a certificate of merger (the “Certificate of Merger”) with the Ohio Secretary of State (the “Ohio Secretary”). The Merger will become effective as of the date and time specified in the Certificate of Merger (such date and time, the “Effective Time”).

1.4 Effects of the Merger. At and after the Effective Time, the Merger will have the effects set forth in the applicable provisions of the OGCL.

1.5 Conversion of Commercial Bancshares Shares. At the Effective Time, by virtue of the Merger and without any action on the part of First Defiance, Commercial Bancshares or the holder of any of the following securities:

(a) Subject to Sections 1.6 and 2.2, each share of the common stock, without par value, of Commercial Bancshares issued and outstanding immediately prior to the Effective Time (“Commercial Bancshares Share”), except for Commercial Bancshares Shares owned by Commercial Bancshares as treasury stock or otherwise owned by Commercial Bancshares or First Defiance (in each case other than Commercial Bancshares Shares (i) held in any Commercial Bancshares Benefit Plans or related trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity and (ii) held, directly or indirectly, in respect of debts previously contracted (collectively, the “Exception Shares”)) and Dissenting Shares, will be converted, in accordance with the procedures set forth in this Agreement, into the right to receive, without interest the following (collectively, the “Merger Consideration”):

(i) $51.00 in cash (the “Cash Consideration”) for each Commercial Bancshares Share with respect to which an election to receive cash has been effectively made and not revoked or lost pursuant to Section 1.6 (a “Cash Election”) (such Commercial Bancshares Shares collectively, “Cash Election Shares”); or

(ii) 1.1808 First Defiance Shares (the “Exchange Ratio,” and such First Defiance Shares, the “Stock Consideration”) for each Commercial Bancshares Share with respect to which an election to receive shares, $.01 par value per share, of First Defiance common stock (“First Defiance Shares”) has been effectively made and not revoked or lost pursuant to Section 1.6 (a “Stock Election”) (such Commercial Bancshares Shares collectively, “Stock Election Shares”); or

(iii) for each Commercial Bancshares Share, other than Commercial Bancshares Shares as to which a Cash Election or a Stock Election has been effectively made and not revoked (collectively, the “Non-Election Shares”), the right to receive from First Defiance such Cash Consideration or Stock Consideration as is determined in accordance with Section 1.5(b).

(b) (i) Notwithstanding any other provision contained in this Agreement (other than Section 1.5(c)), the total number of Commercial Bancshares Shares to be converted into the Stock Consideration pursuant to Section 1.5(a) and 1.5(b)(iii) (the “Stock Conversion Number”) will equal the product obtained by multiplying (x) the number of Commercial Bancshares Shares issued and outstanding immediately prior to the Effective Time by (y) 0.80 (the “Stock Proportion Number”), with such product rounded up to the nearest whole share. All of the other Commercial Bancshares Shares (except for Commercial Bancshares Shares owned directly by Commercial Bancshares or First Defiance and Dissenting Shares) will be converted into the Cash Consideration.

-2-

(ii) As soon as practicable on or within not more than five business days after the Closing Date, First Defiance will cause the Exchange Agent to effect the allocation among holders of Commercial Bancshares Shares of rights to receive the Cash Consideration and the Stock Consideration as follows:

(1) If the aggregate number of Commercial Bancshares Shares with respect to which Stock Elections are made (the “Stock Election Number”) exceeds the Stock Conversion Number, then all Cash Election Shares and all Non-Election Shares of each holder thereof will be converted into the right to receive the Cash Consideration, and Stock Election Shares of each holder thereof will be converted into the right to receive the Stock Consideration in respect of that number of Stock Election Shares equal to 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 the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of such holder’s Stock Election Shares being converted into the right to receive the Cash Consideration; and

(2) If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Shares shall be converted into the right to receive the Stock Consideration and the Non-Election Shares and Cash Election Shares shall be treated in the following manner:

(A) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and the Non-Election Shares of each holder thereof shall convert into the right to receive the Stock Consideration in respect of that number of Non-Election Shares 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 Shortfall Number and the denominator of which is 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 Cash Consideration; or

(B) If the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and Cash Election Shares of each holder thereof shall convert into the right to receive the Stock Consideration in respect of that number of Cash Election Shares equal to 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 the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares 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 Cash Consideration.

-3-

(c) Notwithstanding anything in this Agreement to the contrary, to preserve the status of the Merger as a “reorganization” within the meaning of Section 368(a) of the Code, if the aggregate value of the First Defiance Shares to be issued in connection with the Merger (for the avoidance of doubt, excluding the value of fractional shares for which cash is to be paid pursuant to Section 1.5(d)), based upon the closing price of the First Defiance Shares as reported on The NASDAQ Stock Market (the “NASDAQ”) on the trading day immediately preceding the Effective Time (the “Aggregate Share Consideration”), would be less than 40% of the sum of (i) the Aggregate Cash Consideration and (ii) the Aggregate Share Consideration (collectively, the “Total Consideration”), then First Defiance shall increase the Stock Consideration and decrease the Cash Consideration proportionately and to the minimum extent necessary for the Aggregate Share Consideration to be equal to 40% of the Total Consideration (calculated using such increased Stock Consideration and decreased Cash Consideration). For purposes of this Agreement, the “Aggregate Cash Consideration” shall be the sum of (i) the total amount of Cash Consideration paid pursuant to Section 1.5(a)(i) and/or 1.5(b); (ii) cash paid in lieu of fractional First Defiance Shares pursuant to Section 1.5(d); and (iii) cash paid to holders of Dissenting Shares.

(d) No certificate or scrip representing a fractional First Defiance Share shall be issued in the Merger. Each holder of Commercial Bancshares Shares who would otherwise be entitled to receive a fractional First Defiance Share shall receive an amount of cash equal to the product obtained by multiplying (i) the fractional First Defiance Share interest to which such holder (after taking into account all Commercial Bancshares Shares held at the Effective Time by such holder) would otherwise be entitled by (ii) $51.00.

(e) Any treasury shares held by Commercial Bancshares and any Commercial Bancshares Shares owned by First Defiance for its own account will be cancelled and retired at the Effective Time, and no consideration will be issued in exchange.

(f) Each option to acquire a Commercial Bancshares Share (each a “Commercial Bancshares Stock Option”) that is exercisable immediately prior to the Effective Time or will become exercisable as a result of the Merger being a “change of control” under the terms of the Commercial Bancshares 2009 Stock Incentive Plan will be terminated immediately prior to the Effective Time and entitled to receive, in lieu of each Commercial Bancshares Share that would otherwise have been issuable upon exercise thereof, an amount in cash equal to the excess, if any, of $51.00 over the exercise price of such Commercial Bancshares Stock Option.

-4-

(g) All of the Commercial Bancshares Shares converted into the right to receive the Merger Consideration pursuant to this Article I will no longer be outstanding and will automatically be cancelled and cease to exist as of the Effective Time, and each certificate (each, an “Old Certificate,” it being understood that any reference herein to “Old Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of Commercial Bancshares Shares) previously representing any such Commercial Bancshares Shares will thereafter represent only the right to receive the Merger Consideration described in this Section 1.5. Old Certificates previously representing Commercial Bancshares Shares that are to receive the Stock Consideration will be exchanged for certificates or, at First Defiance’s option, evidence of shares in book entry form (collectively, referred to herein as “New Certificates”), representing whole First Defiance Shares as set forth in Section 1.5(a) (together with any dividends or distributions with respect thereto and cash in lieu of fractional shares issued in consideration therefor) upon the surrender of such Old Certificates in accordance with Section 2.2, without any interest thereon. If, between the date of this Agreement and the Effective Time, the outstanding Commercial Bancshares Shares or First Defiance Shares are increased, decreased, changed into or exchanged for a different number or kind of shares or securities, in any such case as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give holders of Commercial Bancshares Shares the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing in this sentence shall be construed to permit First Defiance or Commercial Bancshares to take any action with respect to its securities that is prohibited by the terms of this Agreement.

(h) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all Commercial Bancshares Shares that are owned by Commercial Bancshares or First Defiance (in each case other than the Exception Shares) or by any direct or indirect Commercial Bancshares Subsidiary prior to the Effective Time will be cancelled and cease to exist, and no consideration will be delivered in exchange therefor.

1.6 Dissenters Rights. Notwithstanding anything in this Agreement to the contrary, any issued and outstanding Commercial Bancshares Shares held by a person (a “Dissenting Shareholder”) who has not voted in favor of, or consented to, the adoption of this Agreement and has complied with all the provisions of the OGCL concerning the right of holders of Commercial Bancshares Shares to require payment of the fair cash value of such Commercial Bancshares Shares (the “Dissenting Shares”), in accordance with Sections 1701.84 and 1701.85 of the OGCL, will not be converted into the right to receive the consideration as described in Section 1.5(a), but will become the right to receive such consideration as may be determined to be due to such Dissenting Shareholder pursuant to the procedures set forth in Section 1701.85 of the OGCL. If such Dissenting Shareholder withdraws its demand for fair cash value or fails to perfect or otherwise loses its rights as a dissenting shareholder, in any case pursuant to the OGCL, each of such Dissenting Shareholder’s Commercial Bancshares Shares will be treated as though such Commercial Bancshares Shares had been converted into the right to receive the Stock Consideration and/or Cash Consideration as determined in First Defiance’s sole discretion. Commercial Bancshares will promptly notify First Defiance of each shareholder who asserts rights as a Dissenting Shareholder following receipt of such shareholder’s written demand delivered as provided in Section 1701.85 of the OGCL. Prior to the Effective Time, Commercial Bancshares will not, except with the prior written consent of First Defiance, voluntarily make any payment or commit or agree to make any payment, or settle or commit or offer to settle, any rights of a Dissenting Shareholder asserted under Section 1701.85 of the OGCL.

1.7 First Defiance Shares. At and after the Effective Time, each First Defiance Share issued and outstanding immediately prior to the Effective Time will remain issued and outstanding and not be affected by the Merger.

-5-

1.8 Articles of Incorporation of Surviving Company. At the Effective Time, the Articles of Incorporation of First Defiance (the “First Defiance Articles”), as in effect at the Effective Time, will be the Articles of Incorporation of the Surviving Company until thereafter amended in accordance with applicable law.

1.9 Code of Regulations of Surviving Company. At the Effective Time, the Code of Regulations of First Defiance (the “First Defiance Code of Regulations”), as in effect immediately prior to the Effective Time, will be the Code of Regulations of the Surviving Company until thereafter amended in accordance with applicable law.

1.10 Tax Consequences. It is intended that the Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a “plan of reorganization” within the meaning of Treasury Regulation Sections 1.368-2(g) and 1.368-3(a).

1.11 Bank Merger. Immediately following the Merger, or at such later time as First Defiance may determine in its sole discretion, The Commercial Savings Bank (“Commercial Bank”), an Ohio bank and a wholly owned Subsidiary of Commercial Bancshares, will merge (the “Bank Merger”) with and into First Federal Bank of the Midwest (“First Federal”), a federal savings bank and a wholly owned Subsidiary of First Defiance. First Federal will be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of Commercial Bank will cease. On the date of this Agreement, First Federal and Commercial Bank entered into the agreement and plan of merger attached hereto as Exhibit A (the “Bank Merger Agreement”). Prior to the Effective Time, Commercial Bancshares will cause Commercial Bank, and First Defiance will cause First Federal, to execute such certificates or articles of merger and such other documents and certificates as are necessary to effectuate the Bank Merger (“Bank Merger Certificates”).

ARTICLE II

EXCHANGE OF SHARES

2.1 First Defiance to Make Shares and Cash Available. At or prior to the Effective Time, First Defiance will deposit, or will cause to be deposited, with a bank or trust company designated by First Defiance (the “Exchange Agent”), for the benefit of the holders of Old Certificates, for exchange in accordance with this Article II, a sufficient amount of cash to be paid in exchange for Commercial Bancshares Shares that are to receive the Cash Consideration, and a sufficient number of First Defiance Shares to be exchanged for the Commercial Bancshares Shares that are to receive the Stock Consideration (such cash and New Certificates, together with any dividends or disbursements, the “Exchange Fund”). The Exchange Fund will be held in trust for holders of Commercial Bancshares Shares until distributed to such holders pursuant to this Agreement.

-6-

2.2 Exchange of Commercial Bancshares Certificates; Election Forms.

(a) Prior to the Election Period, the Exchange Agent will mail to each holder of record of Commercial Bancshares Shares a form letter of transmittal and instructions for use in surrendering for exchange the Old Certificates, together with an election form (“Election Form”). Holders of uncertificated Commercial Bancshares Shares shall be mailed an Election Form. The letter of transmittal will specify that the risk of loss and title to the Old Certificates will pass only upon delivery of such certificates as specified in the letter of transmittal. Each Election Form will permit the holder (or in the case of nominee record holders, the beneficial owner through proper instructions and documentation) to (i) elect to receive the Stock Consideration with respect to the number of such holder’s Commercial Bancshares Shares specified in the Election Form, (ii) elect to receive the Cash Consideration with respect to the number of such holder’s Commercial Bancshares Shares specified in the Election Form, or (iii) indicate that such holder makes no election as to such holder’s Commercial Bancshares Shares. For purposes of this Agreement, the term “Election Period” will mean the period as First Defiance and Commercial Bancshares may agree, during which holders of Commercial Bancshares Shares may validly elect the form of consideration to be received for Commercial Bancshares Shares, occurring between (i) the date of mailing of the S-4 and (ii) the third business day immediately preceding the Effective Time. Any election will have been properly made only if the Exchange Agent has actually received a properly completed Election Form accompanied by one or more Old Certificates, if such Commercial Bancshares Shares are certificated by 5:00 p.m. Eastern Time on the last day of the Election Period (the “Election Deadline”). A submitted Election Form may be revoked or changed by written notice to the Exchange Agent only if such revocation or change is actually received by the Exchange Agent by the Election Deadline. Commercial Bancshares Shares as to which a holder does not submit a properly completed Election Form accompanied by, if applicable, Old Certificates, by the Election Deadline will be Non-Election Shares. The Exchange Agent will make all determinations as to when any election, modification or revocation has been received and whether any such election, modification or revocation has been properly made.

(b) All payments made upon the surrender of Old Certificates pursuant to this Agreement will be deemed to have been made in full satisfaction of all rights pertaining to the shares evidenced by such Old Certificates.

(c) If any Old Certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if required by the Exchange Agent or First Defiance, in their sole discretion, the posting by such person of a bond in such amount as First Defiance may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the cash and/or First Defiance Shares (and cash in lieu of fractional First Defiance Share interests, if any) deliverable in respect thereof.

-7-

(d) Promptly, and not more than eight (8) business days following the Effective Time, the Exchange Agent will deliver to each holder of Commercial Bancshares Shares of record immediately prior to the Effective Time (other than Dissenting Shares) who has surrendered Old Certificates (and to all holders of uncertificated Commercial Bancshares Shares) and who has properly completed and submitted to First Defiance all documentation reasonably required by First Defiance the Merger Consideration, and any applicable dividends or distributions pursuant to subsection (f) below, to which such holder is entitled. For certificated Commercial Bancshares Shares, no payment will be made until the Old Certificate(s) representing such Commercial Bancshares Shares are surrendered or the procedure regarding lost, stolen or destroyed certificates set forth in Section 2.2(c) has been completed. After the Effective Time and until surrendered, an Old Certificate will represent only the right to receive the Merger Consideration to which the holder is entitled pursuant to Section 1.5, and any applicable dividends or distributions pursuant to subsection (f) below. If any New Certificate representing First Defiance Shares is to be issued in a name other than that in which the Old Certificate(s) surrendered in exchange therefor are registered, it will be a condition of the issuance thereof that the Old Certificate(s) so surrendered will be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange will pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a New Certificate representing First Defiance Shares in any name other than that of the registered holder of the Old Certificate(s) surrendered, or required for any other reason, or will establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) None of First Defiance, Commercial Bancshares, the Exchange Agent or the Surviving Company will be liable to any former holder of Commercial Bancshares Shares for any payment of the Merger Consideration, any cash in lieu of a fractional First Defiance Share interest or any dividends or distributions with respect to First Defiance Shares delivered to a public official if required by any applicable abandoned property, escheat or similar law.

(f) No dividends or other distributions declared after the Effective Time with respect to First Defiance Shares and payable to the holders of record thereof after the Effective Time shall be paid to the holder of any unsurrendered Old Certificate until it is surrendered by the holder thereof. Subject to the effect, if any, of applicable law, after the subsequent surrender and exchange of an Old Certificate, the record holder will be entitled to receive from First Defiance any dividends or other distributions, without any interest thereon, that became payable to the holders of record after the Effective Time with respect to any First Defiance Shares represented by such Old Certificate.

(g) After the Effective Time, there will be no further registration or transfer of Commercial Bancshares Shares on the stock transfer books of Commercial Bancshares.

First Defiance and Commercial Bancshares shall, and shall cause their respective Subsidiaries to, each prepare and file any applications, notices and filings required in order to obtain the Requisite Regulatory Approvals. First Defiance and Commercial Bancshares shall each use, and shall each cause their applicable Subsidiaries to use, reasonable best efforts to obtain each such Requisite Regulatory Approval and any approvals required for the Bank Merger as promptly as reasonably practicable. The parties shall cooperate with each other in connection therewith (including the furnishing of any information and any reasonable undertaking or commitments that may be required to obtain the Requisite Regulatory Approvals) and shall respond as promptly as practicable to the requests of Governmental Entities for documents and information. First Defiance and Commercial Bancshares shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to Commercial Bancshares or First Defiance, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement.

The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated herein.

(c) First Defiance and Commercial Bancshares shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement, the S-4 or any other statement, filing, notice or application made by or on behalf of First Defiance, Commercial Bancshares or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement. Each of First Defiance and Commercial Bancshares agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it specifically for inclusion or incorporation by reference in (i) the S-4 will, at the time the S-4 and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to the shareholders of Commercial Bancshares and at the time of the Commercial Bancshares Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which such statement was made, not misleading, and (iii) any applications, notices and filings required in order to obtain the Requisite Regulatory Approvals will, at the time each is filed, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. Each of First Defiance and Commercial Bancshares further agrees that if it becomes aware that any information furnished by it would cause any of the statements in the S-4 or the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take appropriate steps to correct the S-4 or the Proxy Statement.

(d) First Defiance and Commercial Bancshares shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval will be materially delayed.

6.2 Access to Information.

(a) Upon reasonable notice and subject to applicable laws, each of First Defiance and Commercial Bancshares, for the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, shall, and shall cause each of their respective Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors and other representatives of the other party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, personnel, information technology systems, and records, and each shall reasonably cooperate with the other party in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally (including by entering into customary confidentiality, non-disclosure and similar agreements with such service providers and/or the other party), and, during such period, during normal business hours and in a manner so as not to interfere with normal business operations, each of First Defiance and Commercial Bancshares shall, and shall cause its respective Subsidiaries to, make available to the other party such information concerning its business, properties and personnel as such party may reasonably request. Each party shall use commercially reasonable efforts to minimize any interference with the other party’s regular business operations during any such access. Neither First Defiance nor Commercial Bancshares nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of First Defiance’s or Commercial Bancshares’, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Each of First Defiance and Commercial Bancshares shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of each of the confidentiality agreements, dated April 27, 2016 and August 5, 2016, between First Defiance and Commercial Bancshares (the “Confidentiality Agreements”).

6.3 Commercial Bancshares Shareholder Approval.

(a) Commercial Bancshares shall take, in accordance with applicable law and the Commercial Bancshares Articles and the Commercial Bancshares Code of Regulations, all actions necessary to convene a meeting of its shareholders (the “Commercial Bancshares Meeting”) to be held as soon as reasonably practicable after the S-4 is declared effective for the purpose of obtaining the Requisite Commercial Bancshares Vote required in connection with this Agreement and the Merger. Except in the case of an Adverse Recommendation Change, the Board of Directors of Commercial Bancshares shall use its reasonable best efforts to obtain from the shareholders of Commercial Bancshares the Requisite Commercial Bancshares Vote, including by communicating to its shareholders its recommendation (and including such recommendation in the Proxy Statement) that they adopt and approve this Agreement and the transactions contemplated hereby. Commercial Bancshares shall engage a proxy solicitor reasonably acceptable to First Defiance to assist in the solicitation of proxies from shareholders relating to the Requisite Commercial Bancshares Vote. However, subject to Section 8.1 and Section 8.2, if the Board of Directors of Commercial Bancshares, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it will more likely than not result in a violation of its fiduciary duties under applicable law to continue to recommend this Agreement, then in submitting this Agreement to its shareholders, the Board of Directors of Commercial Bancshares may withhold or withdraw or modify in a manner adverse to First Defiance its recommendation to its shareholders or may submit this Agreement to its shareholders without recommendation (each, an “Adverse Recommendation Change”) (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event the Board of Directors of Commercial Bancshares may communicate the basis for its Adverse Recommendation Change to its shareholders in the Proxy Statement or an appropriate amendment or supplement thereto; provided, that the Board of Directors of Commercial Bancshares may not take any actions under this sentence unless (i) it gives First Defiance at least three (3) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken by the Board of Directors of Commercial Bancshares in response to an Acquisition Proposal, the latest material terms and conditions and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (ii) at the end of such notice period, the Board of Directors of Commercial Bancshares takes into account any amendment or modification to this Agreement proposed by First Defiance and after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to continue to recommend this Agreement. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3.

(b) Except in the case of an Adverse Recommendation Change, Commercial Bancshares shall adjourn or postpone the Commercial Bancshares Meeting, if, as of the time for which such meeting is originally scheduled, there are insufficient Commercial Bancshares Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting, Commercial Bancshares has not received proxies representing a sufficient number of shares necessary to obtain the Requisite Commercial Bancshares Vote. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, the Commercial Bancshares Meeting shall be convened and this Agreement shall be submitted to the shareholders of Commercial Bancshares at the Commercial Bancshares Meeting, for the purpose of voting on the adoption of this Agreement and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve Commercial Bancshares of such obligation. Commercial Bancshares shall only be required to adjourn or postpone the Commercial Bancshares Meeting two (2) times pursuant to the first sentence of this Section 6.3(b).

(c) Each member of the Commercial Bancshares Board of Directors of Commercial Bancshares will execute and deliver to First Defiance a Voting Agreement concurrently with the execution of this Agreement.

First Defiance shall use commercially reasonable efforts to minimize any disruption of Commercial Bancshares' business operations and will indemnify and hold harmless Commercial Bancshares with respect to any damages or losses resulting from or arising out of such assessments. Commercial Bancshares and its Subsidiaries shall cooperate with the reasonable requests of professionals conducting the onsite assessments and agency file reviews.

(b) First Defiance shall have ten days from the receipt of any final report prepared in connection with the environmental investigation activities conducted by First Defiance pursuant to Section 6.4(a) to notify Commercial Bancshares in writing of any material environmental concerns regarding violations of, or actions necessary to comply with, Environmental Laws, regardless of whether Commercial Bancshares, First Defiance or any of their Subsidiaries or another Person is responsible or liable for the costs of remedial or corrective actions related to such violation of, or non-compliance with, Environmental laws. Within ten days of the delivery of such notification, First Defiance shall obtain an estimate or indication as described below regarding the cost of taking remedial and corrective actions or the inability to make such an estimate. Should the cost of taking all remedial and corrective actions and measures required by applicable law, in the aggregate, exceed the sum of $500,000, as reasonably estimated by an environmental expert promptly retained for such purpose by First Defiance and reasonably acceptable to Commercial Bancshares, then First Defiance shall have the right, pursuant to Article VIII and Section 7.02(d) hereof, for a period of ten days following the receipt of such estimate, to terminate this Agreement by providing written notice to Commercial Bancshares within such ten-day period.

(c) Commercial Bancshares will provide to First Defiance evidence of title in the form that is customary for the respective jurisdiction for each Commercial Bancshares Real Property within 15 days after the execution of this Agreement. First Defiance shall have the right pursuant to Article VIII and Section 7.02(d) hereof, to terminate this Agreement by providing written notice to Commercial Bancshares if (i) in the reasonable judgment of First Defiance, such evidence of title identifies a breach regarding the representations and warranties contained in Section 3.18 above with respect to ownership of any Commercial Bancshares Real Property with an individual or aggregate fair market value in excess of $500,000 and (ii) Commercial Bancshares is unwilling or unable to cure such breach within 60 days.

6.6 Employee Matters.

(a) First Defiance will review all of the Commercial Bancshares Benefit Plans to determine whether to maintain, terminate or continue such plans. In the event employee compensation and/or benefits as currently provided by Commercial Bancshares are changed or terminated by First Defiance, in whole or in part, First Defiance shall provide the employees of Commercial Bancshares and its Subsidiaries who become First Defiance or First Federal employees as of the Effective Time (the “Continuing Employees”) with benefits that are, in the aggregate, substantially the same as the benefits provided to similarly situated employees of First Defiance; provided, that until such time as First Defiance fully integrates the Continuing Employees into its plans, participation in the Commercial Bancshares Benefit Plans shall be deemed to satisfy the foregoing standard, it being understood that the Continuing Employees may commence participating in the plans of First Defiance on different dates following the Effective Time with respect to different benefit plans. Any employee of Commercial Bancshares or Commercial Bank who did not have an employment agreement, change in control agreement or severance agreement and who is not eligible for and entitled to a severance benefit under any other severance plan or program maintained by or with Commercial Bancshares, who is not offered employment with First Defiance or First Federal with salary and bonus opportunities substantially the same as the salary and bonus opportunities of their current employment with Commercial Bancshares or Commercial Bank or whose employment is terminated by First Defiance or First Federal (other than for cause) on or within six (6) months of the Effective Time shall receive a cash payment in an amount equal to two weeks of such employee’s current base salary (or average hourly wage over a two week period) for each full year of service, with a minimum payment of four weeks’ base salary or wages and a maximum of 26 weeks base salary or wages payable to each such employee. Nothing set forth herein shall be construed to limit the period of continued health care coverage to which such employee would be entitled under COBRA.

(b) With respect to any employee benefit plans of First Defiance or its Subsidiaries in which any Continuing Employees become eligible to participate on or after the Effective Time (the “New Plans”), First Defiance and its Subsidiaries shall (i) use commercially reasonable efforts to waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents under any New Plans, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Commercial Bancshares Benefit Plan, and (ii) recognize all service of such employees with Commercial Bancshares and its Subsidiaries for all purposes in any New Plan to the same extent that such service was taken into account under the analogous Commercial Bancshares Benefit Plan prior to the Effective Time; provided, that the foregoing service recognition shall not apply (A) to the extent it would result in duplication of benefits for the same period of service, (B) for purposes of benefit accruals under any defined benefit pension plan, or (C) for purposes of any benefit plan that is a frozen plan or provides grandfathered benefits.

(c) First Defiance agrees to assume and honor all Commercial Bancshares Benefit Plans in accordance with their terms as of the date, it being understood that this sentence shall not be construed to limit the ability of First Defiance or any of its Subsidiaries or affiliates to amend or terminate any Commercial Bancshares Benefit Plan to the extent that such amendment or termination is permitted by the terms of the applicable plan.

-49-

(d) Commercial Bancshares shall cause any 401(k) plan sponsored or maintained by Commercial Bancshares (the “Commercial Bancshares 401(k) Plan”) to be terminated effective as of the day immediately prior to the Effective Time and contingent upon the occurrence of the Closing. The Continuing Employees shall be eligible to participate, effective as of the Effective Time, in a 401(k) plan sponsored or maintained by First Defiance or one of its Subsidiaries (a “First Defiance 401(k) Plan”). Commercial Bancshares and First Defiance shall take any and all actions as may be required, including amendments to the Commercial Bancshares 401(k) Plan and/or First Defiance 401(k) Plan to permit Continuing Employees who are then actively employed to make rollover contributions to the First Defiance 401(k) Plan of “eligible rollover distributions” (with the meaning of Section 401(a)(31) of the Code) in the form of cash, notes (in the case of loans) or a combination thereof. Commercial Bancshares shall provide First Defiance with evidence that the Commercial Bancshares 401(k) Plan has been terminated or amended, as applicable, in accordance with this Section 6.6(d); provided, that prior to amending or terminating the Commercial Bancshares 401(k) Plan, Commercial Bancshares shall provide the form and substance of any applicable resolutions or amendments to First Defiance for review and approval.

(e) On and after the date hereof, any broad-based employee notices or communication materials (including any website posting) with respect to employment, compensation or benefits matters addressed in this Agreement or related, directly or indirectly, to the transactions contemplated by this Agreement shall be subject to the prior prompt review and comment of the other party, and the party seeking to distribute any such notice or communication shall consider in good faith revising such notice or communication to reflect any comments or advice that the other party timely provides.

(f) Nothing in this Agreement shall confer upon any employee, officer, director or consultant of Commercial Bancshares or any of its Subsidiaries or affiliates any right to continue in the employ or service of the Surviving Company, Commercial Bancshares, First Defiance, or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Company, Commercial Bancshares, First Defiance or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of Commercial Bancshares or any of its Subsidiaries or affiliates at any time for any reason whatsoever, with or without cause.

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, each of First Defiance and the Surviving Company shall indemnify and hold harmless, to the fullest extent permitted by applicable law, the Commercial Bancshares Articles and the Commercial Bancshares Code of Regulations, each present director and officer of Commercial Bancshares and Commercial Bank (in each case, when acting in such capacity) (collectively, the “Commercial Bancshares Indemnified Parties”) for a period of six years following the Effective Time. No Commercial Bancshares Indemnified Party shall be entitled to such indemnification with respect to a claim (i) if such person fails to cooperate in the defense and investigation of such claim as to which indemnification may be made, (ii) made by such person against First Defiance, Commercial Bancshares or any of their Subsidiaries arising out of or in connection with this Agreement, the transactions contemplated hereby or the conduct of the business of First Defiance, Commercial Bancshares or any of their Subsidiaries, or (iii) if such person fails to deliver such notices (within such person’s control) as may be required under any applicable directors’ and officers’ liability insurance policy to preserve any possible claims of which the claiming party is aware, to the extent such failure results in the denial of payment under such policy.

(b) For a period of six (6) years after the Effective Time, First Defiance shall maintain in effect the current policies of directors’ and officers’ liability insurance maintained by Commercial Bancshares or its Subsidiaries and any similar policies covering fiduciaries under the Commercial Bancshares Benefit Plans (provided, that First Defiance may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the insured) with respect to claims against the present and former officers and directors of Commercial Bancshares or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time (including the transactions contemplated by this Agreement); provided, however, that First Defiance shall not be obligated to expend, on an annual basis, an amount in excess of 125% of the current annual premium paid as of the date hereof by Commercial Bancshares for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then First Defiance shall cause to be maintained policies of insurance that, in First Defiance’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, Commercial Bancshares, in consultation with, but only upon the consent of First Defiance, may (and at the request of First Defiance, Commercial Bancshares shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six-year “tail” policy under Commercial Bancshares’ existing directors’ and officers’ insurance policy and similar policy covering fiduciaries under the Commercial Bancshares Benefit Plans providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed, on an annual basis, the Premium Cap. If a “tail policy” is purchased as provided above, First Defiance shall maintain in full force and effect and not cancel such “tail policy.”

-51-

6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest First Defiance or the Surviving Company with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger, the then current officers and directors of each party to this Agreement and their respective Subsidiaries shall take, or cause to be taken, all such necessary action as may be reasonably requested by the other party, at the expense of the party who makes any such request. The parties will mutually agree on the date of distribution of the assets of the Commercial Bancshares, Inc. Deferred Compensation Plan, as amended and restated January 1, 2006, to its participants, which date selected shall occur no later than the period beginning 30 days prior to and ending on the Effective Time.

6.9 Advice of Changes. First Defiance and Commercial Bancshares shall each promptly advise the other party of any fact, change, event or circumstance known to it (i) that has had or is reasonably likely to have a Material Adverse Effect on it or (ii) which it believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties or covenants contained herein or that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.9 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied.

6.10 Additional Director. First Defiance shall take all appropriate action so that, as of the Effective Time, one (1) current director of Commercial Bancshares to be selected by First Defiance in consultation with Commercial Bancshares shall be appointed as a director of First Defiance.

6.11 Acquisition Proposals.

(a) Commercial Bancshares shall not, and shall cause its Subsidiaries and its and their officers, directors, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to, (ii) engage or participate in any negotiations with any person concerning or (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to, any Acquisition Proposal; provided, that, prior to the receipt of the Requisite Commercial Bancshares Vote, in the event Commercial Bancshares receives an unsolicited bona fide written Acquisition Proposal, it may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished nonpublic information or data and participate in such negotiations or discussions to the extent that its Board of Directors concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, further, that, prior to providing any nonpublic information permitted to be provided pursuant to the foregoing provision, Commercial Bancshares shall have provided such information to First Defiance, and shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the Confidentiality Agreement dated April 27, 2016, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with Commercial Bancshares. Commercial Bancshares will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than First Defiance with respect to any Acquisition Proposal. Commercial Bancshares will promptly (and in any event within one (1) business day) advise First Defiance following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the material terms and conditions of and the identity of the person making such Acquisition Proposal), and will keep First Defiance reasonably apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Commercial Bancshares shall use its reasonable best efforts, subject to applicable law and the fiduciary duties of the Board of Directors of Commercial Bancshares, to enforce any existing confidentiality or standstill agreement to which it or any of its Subsidiaries is a party in accordance with the terms thereof. During the term of this Agreement, Commercial Bancshares shall not, and shall cause its Subsidiaries and its and their Representatives not to on its behalf, enter into any binding acquisition agreement, merger agreement, or other definitive transaction agreement (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.11(a)) relating to any Acquisition Proposal. As used in this Agreement, “Acquisition Proposal” shall mean, other than the transactions contemplated by this Agreement, any offer or proposal 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 Commercial Bancshares and its Subsidiaries or 25% or more of any class of equity or voting securities of Commercial Bancshares or its Subsidiaries whose assets, individually or in the aggregate, constitute more than 25% of the consolidated assets of Commercial Bancshares, (ii) any tender offer or exchange offer that, if consummated, would result in such third party beneficially owning more than 25% of any class of equity or voting securities of Commercial Bancshares or its Subsidiaries whose assets, individually or in the aggregate, constitute more than 25% of the consolidated assets of Commercial Bancshares, or (iii) a merger, consolidation, share exchange or other business combination, reorganization involving Commercial Bancshares or its Subsidiaries whose assets, individually or in the aggregate, constitute more than 25% of the consolidated assets of Commercial Bancshares, except, in each case, any sale of whole loans and securitizations in the ordinary course of business and any bona fide internal reorganization.

(b) Nothing contained in this Agreement shall prevent Commercial Bancshares or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act or Item 1012(a) of Regulation M-A with respect to an Acquisition Proposal or from making any legally required disclosure to Commercial Bancshares’ shareholders; provided, that such Rules will in no way eliminate or modify the effect that any action pursuant to such Rules would otherwise have under this Agreement.

6.12 Public Announcements. Commercial Bancshares and First Defiance shall each use their reasonable best efforts (a) to develop a joint communications plan, (b) to ensure that all press releases and other public statements with respect to the transactions contemplated hereby shall be consistent with such joint communications plan, and (c) except in respect of any announcement required by (i) applicable law or regulation, (ii) a request by a Governmental Entity, (iii) communications that are substantially similar to communications previously approved pursuant to this Section 6.12, (iv) communications permitted by Section 6.3 or Section 6.11 or (v) an obligation pursuant to any listing agreement with or rules of any securities exchange, Commercial Bancshares and First Defiance agree to consult with each other and to obtain the advance approval of the other party (which approval shall not be unreasonably withheld, conditioned or delayed) before issuing any press release or, to the extent practical, otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby.

-53-

6.13 Change of Method. First Defiance may at any time change the method of effecting the Merger if and to the extent requested by First Defiance, and Commercial Bancshares agrees to enter into such amendments to this Agreement as First Defiance may reasonably request in order to give effect to such restructuring; provided, however, that no such change or amendment shall (i) alter or change the amount or kind of the Merger Consideration provided for in this Agreement, (ii) adversely affect the Tax treatment of the Merger with respect to Commercial Bancshares’ shareholders or (iii) be reasonably likely to cause the Closing to be materially delayed or the receipt of the Requisite Regulatory Approvals to be prevented or materially delayed.

6.14 Takeover Statutes. Neither Commercial Bancshares nor First Defiance shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger, or any of the other transactions contemplated hereby, and each of First Defiance and Commercial Bancshares shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each of First Defiance and Commercial Bancshares will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

6.15 Exemption from Liability Under Section 16(b). Commercial Bancshares and First Defiance agree that, in order to most effectively compensate and retain those officers and directors of Commercial Bancshares subject to the reporting requirements of Section 16(a) of the Exchange Act (the “Commercial Bancshares Insiders”), both prior to and after the Effective Time, it is desirable that Commercial Bancshares Insiders not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable law in connection with the conversion of Commercial Bancshares Shares in the Merger, and for that compensatory and retentive purpose agree to the provisions of this Section 6.15. The Boards of Directors of First Defiance and of Commercial Bancshares, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly after the date of this Agreement, and in any event prior to the Effective Time, take all such steps as may be necessary or appropriate to cause (i) any dispositions of Commercial Bancshares Shares and (ii) any acquisitions of First Defiance Shares, in each case pursuant to the transactions contemplated by this Agreement and by any Commercial Bancshares Insiders who, immediately following the Merger, will be officers or directors of First Defiance or of the Surviving Company subject to the reporting requirements of Section 16(a) of the Exchange Act, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable law.

-54-

6.16 Litigation and Claims. Each of First Defiance and Commercial Bancshares shall promptly notify the other party in writing of any action, arbitration, audit, hearing, investigation, litigation, suit, subpoena or summons issued, commenced, brought, conducted or heard by or before, or otherwise involving, any Governmental Entity or arbitrator pending or, to the knowledge of First Defiance or Commercial Bancshares, as applicable, threatened against First Defiance, Commercial Bancshares or any of their respective Subsidiaries that (a) questions or would reasonably be expected to question the validity of this Agreement, the Bank Merger Agreement or the other agreements contemplated hereby or thereby or any actions taken or to be taken by First Defiance, Commercial Bancshares, or their respective Subsidiaries with respect hereto or thereto, or (b) seeks to enjoin or otherwise restrain the transactions contemplated hereby or thereby. Commercial Bancshares shall give First Defiance the opportunity to participate at its own expense in the defense or settlement of any shareholder litigation against Commercial Bancshares and/or its directors or affiliates relating to the transactions contemplated by this Agreement, and no such settlement shall be agreed without First Defiance’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

6.17 No Control of Other Party’s Business. Nothing contained in this Agreement shall give First Defiance, directly or indirectly, the right to control or direct the operations of Commercial Bancshares or its Subsidiaries prior to the Effective Time, and nothing contained in this Agreement shall give Commercial Bancshares, directly or indirectly, the right to control or direct the operations of First Defiance or its Subsidiaries prior to the Effective Time. Prior to the Effective Time, each of First Defiance and Commercial Bancshares shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

TERMINATION AND AMENDMENT

8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after adoption of this Agreement by the shareholders of Commercial Bancshares:

(a) by mutual consent of First Defiance and Commercial Bancshares in a written instrument;

(b) by either First Defiance or Commercial Bancshares if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Merger or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final nonappealable order, injunction or decree permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

(c) by either First Defiance or Commercial Bancshares if the Merger shall not have been consummated on or before June 30, 2017 (the “Termination Date”), unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

(d) by either First Defiance or Commercial Bancshares (provided, that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein) if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of Commercial Bancshares, in the case of a termination by First Defiance, or First Defiance, in the case of a termination by Commercial Bancshares, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2 or Section 7.3, as the case may be, and which is not cured within the earlier of the Termination Date and 30 days following written notice to Commercial Bancshares, in the case of a termination by First Defiance, or First Defiance, in the case of a termination by Commercial Bancshares, or by its nature or timing cannot be cured during such period;

-58-

(e) by First Defiance, if (i) prior to such time as the Requisite Commercial Bancshares Vote is obtained, Commercial Bancshares or the Board of Directors of Commercial Bancshares (A) submits this Agreement to its shareholders without a recommendation for approval, or otherwise withdraws or materially and adversely modifies (or discloses its intention to withdraw or materially and adversely modify) its recommendation as contemplated by Section 6.3(a), or recommends to its shareholders an Acquisition Proposal other than the Merger, or (B) materially breaches its obligations under Section 6.3 or Section 6.11; or (ii) a tender offer or exchange offer for 20% or more of the outstanding Commercial Bancshares Shares is commenced (other than by First Defiance or a Subsidiary thereof), and the Board of Directors of Commercial Bancshares recommends that the shareholders of Commercial Bancshares tender their shares in such tender or exchange offer or otherwise fails to recommend that such shareholders reject such tender offer or exchange offer within the ten (10) business day period specified in Rule 14e-2(a) under the Exchange Act; or

(f) by First Defiance if the Commercial Bancshares’ Total Shareholders' Equity calculated as of the last day of the month prior to the Closing Date is less than $36.2 million. For purposes of this Section 8.1(f), “Total Shareholders’ Equity” means the total shareholders’ equity as reported in the financial statements included in Commercial Bancshares Reports, calculated in accordance with GAAP; provided, however, that such amount will not include any accumulated comprehensive income or any of the following costs and expenses actually incurred by Commercial Bancshares that are directly related to the Merger and are paid or accrued for on or prior to the last day of the month prior to the Closing Date: (i) legal, accounting, professional, advisory, brokerage and fairness opinion fees and expenses (including reimbursable costs), (ii) termination, estimated conversion costs and penalty costs associated with vendor contracts and/or commitments, including data processing contracts and commitments, (iii) the costs and expenses incurred by Commercial Bancshares relating to the printing and mailing of the Proxy Statement and the fees and expenses related to the retention of a proxy solicitor, and (iv) the cost of compensation and other benefits to be provided under each change in control, severance, employment or similar agreement to which Commercial Bancshares or any of its Subsidiaries is a party.

The party desiring to terminate this Agreement pursuant to clause (b), (c), (d), (e) or (f) of this Section 8.1 shall give written notice of such termination to the other party in accordance with Section 9.5, specifying the provision or provisions hereof pursuant to which such termination is affected.

8.2 Effect of Termination.

(a) In the event of termination of this Agreement by either First Defiance or Commercial Bancshares as provided in Section 8.1, this Agreement will become void and have no effect, and none of First Defiance, Commercial Bancshares, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever hereunder, or in connection with the transactions contemplated hereby, except that (i) this Section 8.2 and Article IX shall survive any termination of this Agreement, and (ii) notwithstanding anything to the contrary contained in this Agreement, neither First Defiance nor Commercial Bancshares shall be relieved or released from any liabilities or damages arising out of its fraud or willful and material breach of any provision of this Agreement.

-59-

(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 made known to Commercial Bancshares or shall have been made directly to its shareholders generally or any person shall have publicly announced (and not withdrawn) a bona fide Acquisition Proposal with respect to Commercial Bancshares and (A) thereafter this Agreement is terminated by either First Defiance or Commercial Bancshares pursuant to Section 8.1(c) without the Requisite Commercial Bancshares Vote having been obtained or (B) thereafter this Agreement is terminated by First Defiance pursuant to Section 8.1(d), and (C) prior to the date that is twelve (12) months after the date of such termination, Commercial Bancshares 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, Commercial Bancshares shall, on the earlier of the date of execution of such definitive agreement or the date of consummation of such transaction, pay First Defiance, by wire transfer of same day funds, a fee equal to $2,400,000 (the “Termination Fee”).

(ii) In the event that this Agreement is terminated by First Defiance pursuant to Section 8.1(e), then Commercial Bancshares shall pay First Defiance, by wire transfer of same day funds, the Termination Fee as promptly as reasonably practicable after the date of termination (and in any event, within three (3) business days thereafter).

(b) In no event shall Commercial Bancshares be required to pay the Termination Fee on more than one occasion.

(c) Each of First Defiance and Commercial Bancshares acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if Commercial Bancshares fails promptly to pay the Termination Fee due pursuant to this Section 8.2, and, in order to obtain such payment, First Defiance commences a suit which results in a judgment against Commercial Bancshares for the Termination Fee or any portion thereof, Commercial Bancshares shall pay the costs and expenses of First Defiance (including reasonable attorneys’ fees and expenses) in connection with such suit. In addition, if Commercial Bancshares fails to pay the amounts payable pursuant to this Section 8.2, then Commercial Bancshares 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” (as announced by JPMorgan Chase & Co. or any successor thereto) in effect 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. The amounts payable by Commercial Bancshares pursuant to Section 8.2(a)(i) 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 First Defiance in the event of a termination of this Agreement specified in such section.

WHEREAS, the Shareholders collectively own, either solely or jointly, 205,160.59789 shares of common stock, no par value, of Commercial Bancshares (such common shares, together with all shares of Commercial Bancshares which may hereafter be acquired by the Shareholders prior to the termination of this Agreement, shall be referred to herein as the “Shares”);

WHEREAS, First Defiance and Commercial Bancshares propose to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), which provides, among other things, that Commercial Bancshares will merge with and into First Defiance pursuant to the Merger (this and other capitalized terms used and not defined herein shall have the meanings given to such terms in the Merger Agreement); and

WHEREAS, First Defiance and Commercial Bancshares have made it a condition to their entering into the Merger Agreement that the Shareholders agree to vote the Shares in favor of the adoption of the Merger Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereby agree as follows:

ARTICLE 1

Voting of Shares

1.1 Voting Agreement. The Shareholders, individually and not jointly, hereby agree that, during the time this Agreement is in effect, at any meeting of the shareholders of Commercial Bancshares, however called, and in any action by consent of the shareholders of Commercial Bancshares, they will be present (in person or by proxy) at such meeting so that all of their Shares will be counted for the purpose of determining the presence of a quorum and will vote their Shares (except Shares held in a fiduciary capacity): (i) in favor of the adoption of the Merger Agreement (as amended from time to time) and (ii) against any proposal for any recapitalization, merger, sale of assets or other business combination between Commercial Bancshares or any of its Subsidiaries and any person or entity other than First Defiance or any of its Subsidiaries, or any other action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of Commercial Bancshares under the Merger Agreement or that would result in any of the conditions to the obligations of Commercial Bancshares under the Merger Agreement not being fulfilled. The parties hereto acknowledge and agree that nothing contained herein is intended to restrict any Shareholder from voting or otherwise acting in the Shareholder’s capacity as a director of Commercial Bancshares with respect to any matter.

B-1

ARTICLE 2

Representations and Warranties

Each of the Shareholders, individually and not jointly, hereby represents and warrants to First Defiance as follows:

2.1 Authority Relative to this Agreement. He or she has all necessary power and authority or capacity, as the case may be, to execute and deliver this Agreement, to perform his, or her obligations hereunder and to consummate the transaction contemplated by the Merger Agreement. This Agreement has been duly and validly executed and delivered by the Shareholder and constitutes a legal, valid and binding obligation of such Shareholder, enforceable against such Shareholder in accordance with its terms.

2.2 No Conflict.

(a) The execution and delivery of this Agreement by the Shareholder does not, and the performance of this Agreement by him or her will not (i) conflict with or violate any law, rule, regulation, order, judgment or decree applicable to him or her or by which the Shares are bound, or (ii) result in any breach of or constitute a default (or event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien or encumbrance on any of the Shares held by him or her pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which he or she is a party or by which he or she or any Shares of him or her are bound, except, in the case of clauses (i) and (ii), for any such conflicts, violations, breaches, defaults or other occurrences which would not prevent or delay the performance by such Shareholder of his, her or its obligations under this Agreement.

(b) The execution and delivery of this Agreement by him or her does not, and the performance of this Agreement by him or her will not, require any consent, approval, authorization or permit of, or filing with or notification to, any federal, state, local or foreign regulatory body.

2.3 Title to the Shares. Each of the Shareholders is the owner of the number and class of Shares specified on Annex I hereto, free and clear of all security interests, liens, claims, pledges, options, rights of first refusal, agreements, limitations on voting rights, charges and other encumbrances of any nature whatsoever except as otherwise specified on Annex I.

3.1 Transfer of the Shares. Each of the Shareholders hereby covenants and agrees that, during the term of this Agreement, the Shareholder will not, without the prior written consent of First Defiance, sell, pledge, transfer, or otherwise voluntarily dispose of any of the Shares that are owned by the Shareholder (except Shares held in a fiduciary capacity) or take any other voluntary action which would have the effect of removing the Shareholder’s power to vote his, her or its Shares or which would otherwise be inconsistent with this Agreement.

ARTICLE 4

Miscellaneous

4.1 Termination. This Agreement will terminate on the earlier to occur of (i) the date of consummation of the Merger and (ii) the date of termination of the Merger Agreement for any reason whatsoever.

4.2 Specific Performance.

4.4 Amendment. This Agreement may not be amended except by an instrument in writing signed by all the parties hereto.

4.5 Severability.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

4.6 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Ohio.

4.7 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement.
