AGREEMENT

NOW, THEREFORE, for and in consideration of the foregoing and of the mutual representations, warranties, covenants and agreements contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and subject to the conditions set forth below, the parties, intending to be legally bound, undertake, promise, covenant and agree with each other as follows:

ARTICLE I

THE MERGER

Section 1.01 Merger of Merger Sub with and into CBI. Subject to the terms and conditions of this Agreement, at the Effective Time, Merger Sub will merge with and into CBI in accordance with the provisions of Chapter 10 of the Texas Business Organizations Code (the “TBOC”). CBI will be the surviving corporation in the Merger (the “Surviving Corporation”) and will continue its corporate existence under the TBOC as a wholly-owned subsidiary of FFIN. Upon consummation of the Merger, the separate corporate existence of Merger Sub shall terminate.

Section 1.02 Effects of the Merger. The Merger will have the effects set forth in Section 10.008 of the TBOC. The name of the Surviving Corporation will be “Commercial Bancshares, Inc.”

Section 1.03 Certificate of Formation and Bylaws. The certificate of formation and bylaws of CBI, as in effect immediately before the Effective Time, will be the certificate of formation and bylaws of the Surviving Corporation until thereafter changed or amended as provided by applicable Law.

Section 1.04 Directors and Officers. The directors and officers, respectively, of Merger Sub at the Effective Time will become the directors and officers of the Surviving Corporation and will hold office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the certificate of formation and bylaws of the Surviving Corporation or as otherwise provided by Law.

Section 1.05 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any further action on the part of FFIN, CBI, Merger Sub or any holder of record of the following securities:

(a) Each share of FFIN Stock, outstanding prior to the Effective Time shall remain one validly issued, fully paid and nonassessable share of FFIN Stock after the Effective Time and each outstanding and unexercised option to purchase a share of FFIN Stock shall remain one validly issued and outstanding option to purchase a share of FFIN Stock after the Effective Time.

(b) Except for the Cancelled Shares and Dissenting Shares, each share of common stock, par value $1.00 per share, of CBI (the “CBI Stock”) that is issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall automatically be converted into and become the right to receive, without interest, a number of shares of FFIN Stock rounded to the nearest hundredth of a share equal to the quotient of (i) the CBI Per Share Value, divided by (ii) the FFIN Closing VWAP (the “Merger Consideration”). For purposes of this Agreement, (i) the “CBI Per Share Value”

shall be equal to the quotient of (A) $59,400,000, divided by (B) the number of shares of CBI Stock issued and outstanding immediately prior to the Effective Time, and (ii) “FFIN Closing VWAP” means the volume-weighted average price per share of FFIN Stock for a twenty (20) trading day period, starting with the opening of trading on the twenty-first (21st) trading day prior to the Calculation Date to the closing of trading on the trading day prior to the Calculation Date, rounded to the nearest cent, as reported by Bloomberg Finance L.P.

(c) No certificates representing a fractional share shall be issued by FFIN. In lieu of any fractional share, each holder of CBI Stock entitled to a fractional share, upon surrender of such shares of CBI Stock, shall be entitled to receive from FFIN an amount in cash (without interest), payable in accordance with Section 1.06, rounded to the nearest cent, determined by multiplying the fractional share by the FFIN Closing VWAP.

(d) All shares of CBI Stock to be converted into the right to receive the Merger Consideration pursuant to this Section 1.05 shall no longer be outstanding and shall automatically be cancelled and cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented any such shares of CBI Stock shall thereafter cease to have any rights with respect to such shares of CBI Stock, except the right to receive the proportionate share of the Merger Consideration.

(e) Any shares of CBI Stock that are owned immediately prior to the Effective Time by CBI, FFIN or their respective Subsidiaries (other than (i) shares of CBI Stock held, directly or indirectly, in trust accounts, managed accounts and the like or otherwise held in a fiduciary capacity that are beneficially owned by third parties and (ii) shares of CBI Stock held in respect of a debt previously contracted) shall be canceled and extinguished without any conversion thereof or consideration therefor (the “Cancelled Shares”).

(f) Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted automatically into and become one newly issued, fully paid and non-assessable share of common stock of the Surviving Corporation.

Section 1.06 Exchange Procedures.

(a) Prior to the Effective Time, FFIN shall appoint an exchange agent (the “Exchange Agent”) to act as the exchange agent hereunder.

(b) At or promptly after the Effective Time, FFIN shall deposit with or make available to the Exchange Agent for exchange in accordance with this Section 1.06, the Aggregate Stock Consideration and any cash payable in lieu of fractional shares (collectively, the “Exchange Fund”).

(c) Following receipt of the Requisite CBI Vote and no later than five (5) Business Days after the Effective Time and subject to FFIN’s receipt of a list of CBI’s shareholders in a format that is acceptable to the FFIN, FFIN shall, or shall cause the Exchange Agent to, mail to each holder of record immediately prior to the Effective Time

of certificates (other than with respect to Cancelled Shares and Dissenting Shares) representing shares of CBI Stock (each, a “Certificate,” it being understood that any reference herein to a “Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of CBI Stock), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or an affidavit of loss in lieu of such Certificate and, if reasonably required by FFIN or the Exchange Agent, the posting by such holder of CBI Stock of a bond in such amount as FFIN may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate; provided, that the amount of such bond shall not exceed the amount of Merger Consideration to be received with respect to such Certificate)) to the Exchange Agent and shall be substantially in such form and have such other provisions as shall be prescribed by the Exchange Agent (the “Letter of Transmittal”) and (ii) instructions for use in surrendering each Certificate in exchange for the Merger Consideration, any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to this Section 1.06. The CBI shareholders will be entitled to receive their Merger Consideration only after receipt by the Exchange Agent of a properly completed Letter of Transmittal. If a Letter of Transmittal contains an error, is incomplete or is not accompanied by all appropriate Certificates, then the Exchange Agent will notify that CBI shareholder promptly of the need for further information or documentation.

(d) Within five (5) Business Days after surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, or within five (5) Business Days after the Effective Time for any uncertificated shares of CBI Stock held of record in book-entry form (subject to receipt of any customary tax documentation that may be reasonably requested by the Exchange Agent), the Exchange Agent shall deliver to such holder of CBI Stock the Merger Consideration and any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor in respect of the shares of CBI Stock represented by such holder’s Certificate or Certificates, and each Certificate surrendered will be canceled. FFIN may, at its option, deliver any shares of FFIN Stock in book-entry form. Until so surrendered, each Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration and any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with this Section 1.06, and any dividends or distributions to which such holder is entitled pursuant to this Section 1.06. Notwithstanding anything to the contrary herein, no Certificate or Certificates shall be deemed surrendered to the Exchange Agent prior to the Effective Time.

(e) No dividends or other distributions with respect to FFIN Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of FFIN Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this Section 1.06. However, upon surrender of such Certificate, the Merger Consideration, together with all such undelivered dividends or other distributions without interest, shall be delivered and paid with respect to each share represented by such Certificate. Subject to the effect of applicable abandoned property, escheat or

similar Laws, following surrender of any such Certificate in accordance with this Section 1.06, the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions, if any, with a record date at or after the Effective Time that are payable with respect to the whole shares of FFIN Stock issuable with respect to such Certificate and not paid and/or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of FFIN Stock issuable with respect to such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the FFIN Stock issuable with respect to such Certificate.

(f) In the event of a transfer of ownership of a Certificate representing CBI Stock prior to the Effective Time that is not registered in the stock transfer records of CBI, the Merger Consideration and any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor shall be issued or paid in exchange therefor to a Person other than the Person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such CBI Stock shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a Person other than the registered holder of the Certificate or establish to the satisfaction of FFIN and the Exchange Agent that the Tax has been paid or is not applicable.

(g) FFIN and the Exchange Agent, as the case may be, shall be entitled to deduct and withhold, if necessary, from any consideration otherwise payable pursuant to this Agreement to any Person such amounts as FFIN or the Exchange Agent, 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 amounts are so withheld by FFIN or the Exchange Agent, as the case may be, and remitted to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made by FFIN or the Exchange Agent, as the case may be.

(h) Any portion of the Exchange Fund that remains unclaimed by the shareholders of CBI at the expiration of six (6) months after the Effective Time shall be paid to FFIN. In such event, any former shareholders of CBI who have not theretofore complied with this Section 1.06 shall thereafter look only to FFIN with respect to the Merger Consideration, any cash in lieu of any fractional shares and any unpaid dividends and distributions on the FFIN Stock deliverable in respect of each share represented by a Certificate such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon.

(i) Any other provision of this Agreement notwithstanding, none of FFIN, the Surviving Corporation or the Exchange Agent shall be liable to a holder of CBI Stock for any amounts paid or property delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar law.

Section 1.07 Adjusted Equity Calculation.

(a) The Adjusted Equity of CBI shall be calculated in accordance with this Section 1.07 as of the close of business on the fifth Business Day immediately preceding the Closing Date, or such other date as mutually agreeable to the parties hereto (the “Calculation Date”).

(b) For purposes of this Agreement, “Adjusted Equity” means the total consolidated shareholders’ equity of CBI, calculated on a consolidated basis and in accordance with GAAP and adjusted to reflect the payment of or accrual for all CBI Merger Costs through the Closing Date (including reasonable estimates mutually agreeable to FFIN and CBI for the period from the Calculation Date through the Closing Date). For comparative purposes and without any binding effect on the parties with respect to this Section 1.07(b), the total consolidated shareholders’ equity of CBI as of March 31, 2017 was $42,402,486. For purposes of this Agreement, “CBI Merger Costs” means, on an after-tax basis, (i) the legal, professional, investment banking, consulting and accounting fees and expenses of CBI associated with the Merger, including any cost to obtain any opinion as to the financial fairness of the Merger, (ii) all fees related to obtaining the Tail Coverage, (iii) the payments owed by CBI or the Bank to those employees and in such amounts listed on Confidential Schedule 1.07(b), including, without limitation any stay-pay or retention bonus amounts (other than stay-pay or retention bonus amounts requested or directed by FFIN) or change in control payments (all of which shall be reflected on Confidential Schedule 1.07(b) including the name of the recipient, the amount of such payment and with respect to any stay-pay or retention bonus arrangements, the date through which the recipient must remain employed by the Surviving Corporation to receive the stay-pay or retention bonus amount), (iv) the cost of terminating any employment related agreements and obligations (including any non-competition agreements, option agreements or equity based plans) including, among others, the employment agreements and Executive Survivor Income Agreements set forth on Confidential Schedule 5.15(b), (v) if requested by FFIN, a mutually agreeable estimate of the cost of obtaining a determination letter from the Internal Revenue Service (the “IRS”) in connection with the termination of a Retirement Plan, (vi) any federal income tax obligations, franchise tax obligations or real property tax obligations incurred prior to the Effective Time, (vii) the accrual or payment of all of the costs, fees, expenses and penalties necessary to be paid by CBI or the Bank in connection with any contract termination required pursuant to this Agreement, including, without limitation, all costs, fees, expenses and penalties associated with the termination of the data processing or technology contracts or other contracts contemplated by Section 5.15(a) hereof, and (viii) a reduction in the amount of the total consolidated shareholders’ equity of CBI equal to the amount of the gain recognized on the property located at ▇▇▇▇▇ ▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇. ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇. In addition, any dividends (whether paid or declared) by CBI shall have been recorded by CBI as a reduction of Adjusted Equity; provided, however, that the Dividend Payment pursuant to Section 1.08 shall be excluded from the calculation of Adjusted Equity.

Section 1.08 Dividend to Shareholders. On the Closing Date and prior to the Effective Time, CBI shall pay a dividend to the holders of CBI Stock in an aggregate amount equal to (such amount, the “Dividend Payment”) the sum of (a) the amount by which the Adjusted Equity is greater than $42,402,486, if any, plus (b) $15,600,000, (c) minus the amount by which the Adjusted Equity is less than $42,402,486, if any.

Section 1.09 Tax Treatment. For U.S. federal income Tax purposes, it is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute, and is hereby adopted as, a “plan of reorganization” within the meaning of Treasury Regulation Section 1.368-2(g). From and after the date of this Agreement and until the Closing Date, each party hereto shall use its reasonable best efforts to cause the Merger to qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action not to be taken, which action or failure to act could reasonably be expected to prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code.

Section 1.10 Modification of Structure. Notwithstanding any provision of this Agreement to the contrary, FFIN may elect, subject to the filing of all necessary applications and the receipt of all required regulatory approvals, to modify the structure of the transactions contemplated hereby so long as (i) there are no material adverse federal or state income tax consequences to the holders of CBI Stock as a result of such modification (taken as a whole and not with respect to any individual holder), (ii) the after tax consideration to be paid to the holders of CBI Stock is not changed in kind or reduced in amount, and (iii) such modification will not be likely to materially delay or jeopardize receipt of any required regulatory approvals or the Closing.

Section 1.11 Dissenting Shareholders. Notwithstanding anything in this Agreement to the contrary, each share of CBI Stock that is outstanding immediately prior to the Effective Time and that is held by shareholders (“Dissenting Shares”) who have not voted such shares in favor of this Agreement, the Merger and the transactions contemplated hereby and who will have otherwise complied with the terms and provisions of Chapter 10, Subchapter H of the TBOC will be entitled to those rights and remedies set forth in Chapter 10, Subchapter H of the TBOC; but if a shareholder fails to perfect, withdraws or otherwise loses any such right or remedy granted by the TBOC, each such Dissenting Shares shall be deemed to have been converted into and to have become exchangeable for, the right to receive the Merger Consideration without any interest thereon in accordance with the provisions of this Article I.

Section 1.12 Second Step Merger. On the Closing Date and as soon as reasonably practicable following the Effective Time, in accordance with the TBOC, FFIN shall cause the Surviving Corporation to be merged with and into FFIN in the Second Step Merger, with FFIN surviving the Second Step Merger and continuing its existence under the Laws of the State of Texas, and the separate corporate existence of the Surviving Corporation ceasing as of the Second Effective Time.

FFIN will notify CBI prior to any physical inspections of the Property, and CBI may place reasonable restrictions on the time of such inspections.

CBI will have the opportunity to correct any objected to violations or conditions to FFIN’s reasonable satisfaction prior to the date that is one hundred five (105) days after the date of this Agreement.

This VOTING AGREEMENT (this “Agreement”) dated as of October 12, 2017, is executed by and among First Financial Bankshares, Inc. (“FFIN”), a Texas corporation and registered bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHCA”), Commercial Bancshares, Inc., a Texas corporation and registered bank holding company under the BHCA (“CBI”), F. ▇▇▇▇▇ ▇▇▇▇▇▇ (“Proxy Holder”), as proxy, and the shareholders of CBI listed on the signature pages to this Agreement (referred to herein individually as a “Shareholder” and collectively as the “Shareholders”). Terms with their initial letters capitalized and not otherwise defined herein have the meanings given them in the Merger Agreement (as defined below).

RECITALS

WHEREAS, concurrently with the execution of this Agreement, FFIN, Kingwood Merger Sub, Inc. (“Merger Sub”), a Texas corporation and wholly-owned subsidiary of FFIN, and CBI, have entered into that certain Agreement and Plan of Reorganization, dated as of the date hereof (the “Merger Agreement”), providing for, among other things, FFIN’s acquisition of CBI through the merger of Merger Sub with and into CBI, with CBI surviving the merger as a wholly-owned subsidiary of FFIN (the “Merger”);

WHEREAS, the Merger Agreement provides that all of the issued and outstanding shares of common stock, par value $1.00 per share, of CBI (the “Common Stock”), other than Cancelled Shares and Dissenting Shares, will be exchanged for such consideration as set forth in the Merger Agreement;

WHEREAS, as a condition and inducement to FFIN’s willingness to enter into the Merger Agreement, each of the Shareholders have agreed to vote their shares of Common Stock in favor of approval of the Merger Agreement and the transactions contemplated thereby; and

WHEREAS, FFIN is relying on the agreements set forth herein in incurring expenses in reviewing the business of CBI and Commercial State Bank, a Texas state bank chartered in El Campo, Texas and a wholly-owned subsidiary of CBI (the “Bank”), in proceeding with the filing of applications for regulatory approvals, and in undertaking other actions necessary for the consummation of the Merger, and the Shareholders are benefiting both from such expenditures by FFIN and by the terms of the Merger Agreement.

NOW, THEREFORE, for and in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, CBI, FFIN, the Proxy Holder and the Shareholders undertake, promise, covenant and agree with each other as follows:

AGREEMENT

1. Each Shareholder, being the registered owner of the number of shares of Common Stock set forth below the Shareholder’s name on the signature pages hereto (for each such Shareholder, the “Shares”), will vote, direct to vote, or act by consent with respect to:

(a)

the Shares;

B-1

(b)

all Common Stock the Shareholder owns as of the record date of any meeting of the shareholders of CBI or otherwise as of the date of such vote or consent; and

(c)

all Common Stock the Shareholder owns beneficially and has the power and authority to direct the voting thereof as of the record date of any meeting of the shareholders of CBI or otherwise as of the date of such vote or consent

(clauses (a), (b) and (c), collectively, the “Proxy Shares”), in favor of approval of the Merger and any other transactions contemplated by the Merger Agreement.

2. If CBI conducts a meeting of or otherwise seeks approval of its shareholders with respect to any Acquisition Proposal or any other matter that may contradict this Agreement or the Merger Agreement or may prevent FFIN or CBI from completing the Merger, then the Shareholders will vote the Proxy Shares against the approval of the Acquisition Proposal or otherwise act in the manner most favorable to completing the Merger and the transactions contemplated by the Merger Agreement.

3. Each Shareholder shall not invite or seek any Acquisition Proposal, support (or publicly suggest that anyone else should support) any Acquisition Proposal that may be made, or ask the CBI Board to consider, support or seek any Acquisition Proposal or otherwise take any action designed to make any Acquisition Proposal more likely. None of the Shareholders shall meet or otherwise communicate with any Person that makes or is considering making an Acquisition Proposal or any representative of such Person after becoming aware that the Person has made or is considering making an Acquisition Proposal. Each Shareholder shall promptly advise CBI of each contact the Shareholder or any of the Shareholder’s representatives may receive from any Person relating to any Acquisition Proposal or otherwise indicating that any Person may wish to participate or engage in any transaction arising out of any Acquisition Proposal and will provide CBI with all information FFIN requests that is available to the Shareholder regarding any such Acquisition Proposal or possible Acquisition Proposal. Each Shareholder will not make any claim or join in any litigation alleging that the CBI Board is required to consider, endorse or support any Acquisition Proposal or to invite or seek any Acquisition Proposal. Each Shareholder shall not take any other action that is reasonably likely to make consummation of the Merger less likely or to impair FFIN’s ability to exercise any of the rights granted by the Merger Agreement.

4. Each Shareholder, severally, but not jointly, represents and warrants to FFIN that:

(a)

Shareholder (i) owns beneficially (as such term is defined in Rule 13d-3 under the Exchange Act) all of the Shares free and clear of all liens or encumbrances, and (ii) except pursuant hereto, there are no options, warrants or other rights, agreements, arrangements or commitments of any character to which Shareholder is a party relating to the pledge, disposition or voting of any of the Shares and there are no voting trusts or voting agreements with respect to the Shares.

B-2

(c)

Shareholder has full power and authority and legal capacity to enter into, execute and deliver this Agreement and to perform fully Shareholder’s obligations hereunder (including the proxy described in Section 5 below). This Agreement has been duly and validly executed and delivered by Shareholder and constitutes the legal, valid and binding obligation of Shareholder, enforceable against Shareholder in accordance with its terms.

(d)

None of the execution and delivery of this Agreement by Shareholder, the consummation by Shareholder of the transactions contemplated hereby or compliance by Shareholder with any of the provisions hereof will conflict with or result in a breach, or constitute a default (with or without notice or lapse of time or both) under any provision of, any trust agreement, loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, instrument or law applicable to Shareholder or to Shareholder’s property or assets.

(e)

No consent, approval or authorization of, or designation, declaration or filing with, any Governmental Entity or other Person on the part of Shareholder is required in connection with the valid execution and delivery of this Agreement. No consent of Shareholder’s spouse is necessary under any “community property” or other laws in order for Shareholder to enter into and perform its obligations under this Agreement.

(f)

Shareholder hereby (a) confirms his or her knowledge of the availability of the rights of dissenting shareholders under the Texas Business Organizations Code (the “TBOC”) with respect to the Merger and (b) confirms receipt of a copy of the provisions of the TBOC related to the rights of dissenting shareholders. Each Shareholder hereby waives and agrees not to assert, and shall use its best efforts to cause any of its Affiliates who hold of record any of the Shareholder’s Shares to waive and not to assert, any appraisal rights with respect to the Merger that the Shareholder or such Affiliate may now or hereafter have with respect to any Shares (or any other shares of capital stock of CBI that the Shareholder shall hold of record at the time that the Shareholder may be entitled to assert appraisal rights with respect to the Merger) whether pursuant to the TBOC or otherwise.

5. In order to better effect the provisions of Sections 1 and 2 of this Agreement, each Shareholder hereby revokes any previously executed proxies and hereby constitutes and appoints Proxy Holder with full power of substitution, his true and lawful proxy and attorney-in-fact to vote at any meeting of the shareholders of CBI all of the Proxy Shares in favor of the approval of the Merger and any other transactions contemplated by the Merger Agreement, with such modifications to the Merger Agreement as the parties thereto may make; but this proxy will not apply with respect to any vote on approval of the Merger contemplated by the Merger Agreement if the Merger Agreement is modified so as to (i) reduce the amount of consideration or the form of consideration to be received by the Shareholder or (ii) materially alter the tax consequences of the receipt thereof under the Merger Agreement in its present form. This proxy shall be limited strictly and solely to the power and authority to vote the Proxy Shares in the manner and for the purpose set forth in Sections 1 and 2 of this Agreement and shall not extend to any other matters.

6. Each Shareholder hereby covenants and agrees that until this Agreement is terminated in accordance with its terms, such Shareholder will not, and will not agree

B-3

to, without the consent of FFIN, directly or indirectly, sell, transfer, assign, pledge, encumber, hypothecate, cause to be redeemed or otherwise dispose of (any such transaction, a “Transfer”) any of the Shares or grant any proxy or interest in or with respect to any Shares or deposit any such Shares into a voting trust or enter into another voting agreement or arrangement with respect to such Shares except as contemplated by this Agreement. Any attempted Transfer of Shares or any interest therein in violation of this Section shall be null and void. This Section shall not prohibit a Transfer of the Shares to any member of Shareholder’s immediate family, to another Shareholder, to a trust for the benefit of Shareholder or any member of Shareholder’s immediate family, or upon the death of Shareholder; provided, that a Transfer referred to in this sentence shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to FFIN, to be bound by all of the terms of this Agreement.

7. Proxy Holder, by his execution below, agrees to (A) vote all of the Shareholders’ Proxy Shares at any meeting of the shareholders of CBI, in favor of the approval of the Merger and any other transactions contemplated by the Merger Agreement, with such modifications to the Merger Agreement as the parties thereto may make; but this proxy will not apply with respect to any vote on approval of the Merger contemplated by the Merger Agreement if the Merger Agreement is modified so as to (i) reduce the amount of consideration or the form of consideration to be received by the Shareholder or (ii) materially alter the tax consequences of the receipt thereof under the Merger Agreement in its present form, and (B) in the event of an Acquisition Proposal, to vote all of the Shareholders’ Proxy Shares at any meeting of the shareholders of CBI, against the approval of the Acquisition Proposal or otherwise act in the manner most favorable to completing the Merger and the transactions contemplated by the Merger Agreement.

8. Each Shareholder acknowledges that FFIN and CBI are relying on this Agreement in incurring expenses in connection with FFIN’s reviewing CBI and the Bank’s business, in CBI’s cooperation with FFIN’s preparation of a proxy statement and Registration Statement on Form S-4, in FFIN’s proceeding with the filing of applications for regulatory approvals, and in their undertaking other actions necessary for completing the Merger and that THE PROXY GRANTED HEREBY IS COUPLED WITH AN INTEREST AND IS IRREVOCABLE TO THE FULL EXTENT PERMITTED BY APPLICABLE LAW, INCLUDING TO THE EXTENT APPLICABLE, SECTION 21.369 OF THE TBOC. The Shareholders and CBI acknowledge that the performance of this Agreement is intended to benefit FFIN.

9. This Agreement shall remain in effect until the earlier to occur of (a) the termination of the Merger Agreement, as it may be amended or extended from time to time, pursuant to the terms and conditions contained therein or (b) completion of the transactions contemplated by the Merger Agreement.

10. Proxy Holder may, in his sole discretion, appoint a substitute proxy to act as Proxy Holder under this Agreement; provided, that any substitute proxy shall agree in writing to be bound by the terms and conditions of this Agreement. In the event of the death, disability or incapacity of Proxy Holder, FFIN, in its sole discretion, may appoint a substitute proxy to act as Proxy Holder under this Agreement.

B-4

11. The vote of the Proxy Holder will control in any conflict between his vote of the Proxy Shares and a vote by the substitute proxy holder or the Shareholders of the Proxy Shares, and CBI agrees to recognize the vote of the Proxy Holder instead of the vote of substitute proxy holder or the Shareholders if the substitute proxy holder or the Shareholders do not vote in accordance with Sections 1 and 2 of this Agreement.

12. This Agreement may not be modified, amended, altered or supplemented with respect to a particular Shareholder except upon the execution and delivery of a written agreement executed by FFIN, CBI and that Shareholder. Any such modification, amendment, alteration or supplement shall only apply to the Shareholder(s) executing such written agreement and this Agreement will remain in full force and effect with respect to Shareholders who do not execute such written agreement.

13. For the convenience of the parties hereto, this Agreement may be signed in multiple counterparts, each of which will be deemed an original, and all counterparts hereof so signed by the parties hereto, whether or not such counterpart will bear the execution of each of the parties hereto, will be deemed to be, and is to be construed as, one and the same Agreement. An e-mail or electronic scan in “PDF” format of a signed counterpart of this Agreement will be sufficient to bind the party or parties whose signature(s) appear thereon.

14. This Agreement, the Merger Agreement and the other agreements, documents, schedules and instruments signed and delivered by the parties to each other at the Closing are the full understanding of the parties, a complete allocation of risks between them and a complete and exclusive statement of the terms and conditions of their agreement relating to the subject matter hereof and supersede any and all prior agreements, whether written or oral, that may exist between the parties with respect thereto. Except as otherwise specifically provided in this Agreement, no conditions, usage of trade, course of dealing or performance, understanding or agreement purporting to modify, vary, explain or supplement the terms or conditions of this Agreement is binding unless hereafter made in writing and signed by the party to be bound, and no modification will be effected by the acknowledgment or acceptance of documents containing terms or conditions at variance with or in addition to those set forth in this Agreement.

15. Any and all notices, requests, instructions and other communications required or permitted to be given under this Agreement after the date of this Agreement by any party hereto to any other party may be delivered personally or by nationally recognized overnight courier service or sent by mail or (except in the case of payments) by facsimile transmission or e-mail, at the respective addresses or transmission numbers set forth below and is deemed delivered (a) in the case of personal delivery, facsimile transmission or e-mail, when received; (b) in the case of mail, upon the earlier of actual receipt or five (5) Business Days after deposit in the United States Postal Service, first class certified or registered mail, postage prepaid, return receipt requested; and (c) in the case of an overnight courier service, one (1) Business Day after delivery to such courier service with instructions for overnight delivery. The parties may change their respective addresses and transmission numbers by written notice to all other parties, sent as provided in this Section.

DIRECTOR SUPPORT AGREEMENT

This DIRECTOR SUPPORT AGREEMENT (the “Agreement”) is made and entered into as of October 12, 2017, by and between First Financial Bankshares, Inc., a Texas corporation and registered bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHCA”), with its principal offices in Abilene, Texas (“FFIN”), and , an individual resident of the State of Texas (“Director”). Terms with their initial letters capitalized and not otherwise defined herein have the meanings given them in the Merger Agreement (as defined below).

RECITALS

WHEREAS, FFIN, Kingwood Merger Sub, Inc., a Texas corporation and wholly-owned subsidiary of FFIN (“Merger Sub”), and Commercial Bancshares, Inc., a Texas corporation and registered bank holding company under the BHCA (“CBI”), have entered into an Agreement and Plan of Reorganization, dated as of dated hereof (the “Merger Agreement”), providing for FFIN’s acquisition of CBI through the merger of Merger Sub with and into CBI, with CBI surviving the merger as a wholly-owned subsidiary of FFIN (the “Merger”);

WHEREAS, as a condition and inducement to FFIN’s willingness to enter into the Merger Agreement, FFIN and Director have agreed to enter into this Agreement.

NOW, THEREFORE, in consideration for receipt of such confidential information and trade secrets and in consideration of the premises and mutual covenants contained herein and in the Merger Agreement intending to be legally bound hereby, FFIN and Director agree as follows;

AGREEMENT

1. Director Support. Director agrees to use his or her best efforts to refrain from harming the goodwill of CBI, any Subsidiary of CBI (“CBI Subsidiary”), FFIN or any Subsidiary of FFIN, and their respective customer, client and vendor relationships. During the term of this Agreement, Director agrees also to consider First Financial Bank, National Association, a national association with its principal offices in Abilene, Texas and wholly-owned subsidiary of FFIN, when obtaining banking products or services for his or her personal or business needs.

2. Director Covenants.

(a)

Director acknowledges that he or she has received substantial, valuable consideration, including confidential trade secret and proprietary information relating to the identity and special needs of current and prospective customers of CBI or any CBI Subsidiary, CBI’s and any CBI Subsidiary’s current and prospective services, CBI’s and any CBI Subsidiary’s business projections and market studies, CBI’s and any CBI Subsidiary’s business plans and strategies, CBI’s and any CBI Subsidiary’s studies and information concerning special services unique to CBI or any CBI Subsidiary. Director further acknowledges and agrees that this consideration constitutes fair and adequate consideration for the execution of the non-solicitation and non-competition restrictions set forth below. Accordingly, other than in any capacity for or on behalf of FFIN or any subsidiary of FFIN, Director agrees that Director will not, directly or indirectly, individually or as an employee, partner, officer, director or shareholder or in any other capacity whatsoever:

C-1

solicit the business of any Person or entity who is a customer of CBI or any CBI Subsidiary as of the date of this Agreement or as of the Closing Date on behalf of any other insured depository institution for the purpose of providing financial services to such Person or entity;

ii.

acquire any interest in (directly or indirectly), charter, operate or enter into any franchise or other management agreement with any insured depository institution that has a location within a 35 mile radius of any location of CBI or any CBI Subsidiary (the “Noncompete Area”) (but notwithstanding the foregoing, Director may (1) acquire an ownership interest in any publicly-traded depository institution, so long as that ownership interest does not exceed one (1%) of the total number of shares outstanding of that depository institution, (2) invest in an existing mutual fund that invests, directly or indirectly, in such insured depository institutions), and (3) retain any existing ownership interest in any insured depository institution as disclosed on Schedule 1 attached hereto;

iii.

serve as an officer, director, employee, agent or consultant to any insured depository institution that has a location within the Noncompete Area; or

iv.

establish or operate a branch or other office of an insured depository institution within the Noncompete Area; or

recruit, hire, assist others in recruiting or hiring, discuss employment with, or refer others concerning employment, any person who is, or within the 12 months preceding the Closing Date was, an employee of CBI or any CBI Subsidiary; but nothing in this Section 2(a)(v) applies to employment other than in financial services.

Director may not avoid the purpose and intent of this Section 2(a) by engaging in conduct within the Noncompete Area from a remote location through means such as telecommunications, written correspondence, computer generated or assisted communications, or other similar methods.

(b)

If any court of competent jurisdiction should determine that the terms of this Section 2 are too broad in terms of time, geographic area, lines of commerce or otherwise, that court is to modify and revise any such terms so that they comply with applicable law.

(c)

Director agrees that (i) this Agreement is entered into in connection with the sale to FFIN of CBI and Commercial State Bank, a Texas state bank chartered in El Campo, Texas (the “Bank”), (ii) Director is receiving valuable consideration for this Agreement, (iii) the restrictions imposed upon Director by this Agreement are essential and necessary to ensure FFIN acquires the goodwill of the CBI and the Bank, and (iv) all the restrictions (including particularly the time and geographical limitations) set forth in this Agreement are fair and reasonable.

3. Early Resolution Conference. This Agreement is understood to be clear and enforceable as written and is executed by both parties on that basis. However, should Director later challenge any provision as unclear, unenforceable, or inapplicable to any competitive activity that Director intends to engage in, Director will first notify FFIN in writing and meet with a FFIN representative and a neutral mediator (if FFIN elects to retain one at its expense) to discuss resolution of any disputes between the parties. Director will provide this notice at least twenty-one (21) days before Director engages in any activity on behalf of a competing business or engages in other activity that could foreseeably fall within a questioned restriction. If Director fails to comply with this requirement, Director waives his right to challenge the reasonable scope, clarity, applicability or enforceability of this Agreement and its restrictions at a later time.

C-2

4. Termination. This Agreement and all obligations hereunder will terminate on the earlier of (a) the date the Merger Agreement is terminated pursuant to Section 9.01 of the Merger Agreement or (b) the date that is thirty-six (36) months after the Closing Date.

5. Waiver. Amendment and Modification. Any party may unilaterally waive a right which is solely applicable to it. Such action will be evidenced by a signed written notice. No failure to exercise nor any delay in exercising any right, power or privilege hereunder by any party hereto will operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder will preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver of any party of any right or remedy on any one occasion will not be construed as a bar to any right or remedy that such party would otherwise have on any future occasion or to any right or remedy that any other party may have hereunder. This Agreement may be amended, modified or supplemented only by an instrument in writing executed by each of the parties hereto.

6. Multiple Counterparts. For the convenience of the parties hereto, this Agreement may be signed in multiple counterparts, each of which will be deemed an original, and all counterparts hereof so signed by the parties hereto, whether or not such counterpart will bear the execution of each of the parties hereto, will be deemed to be, and is to be construed as, one and the same Agreement. A telecopy, facsimile or electronic scan in “PDF” format of a signed counterpart of this Agreement will be sufficient to bind the party or parties whose signature(s) appear thereon.

7. GOVERNING LAW. THIS AGREEMENT IS TO BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD FOR THE PROVISIONS THEREOF REGARDING CHOICE OF LAW. VENUE FOR ANY CAUSE OF ACTION BETWEEN THE PARTIES TO THIS AGREEMENT WILL LIE IN ▇▇▇▇▇▇ COUNTY, TEXAS. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. 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 ANY ACTION, SUIT OR PROCEEDING, 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 7.

C-3

8. Binding Effect; Assignment. All of the terms, covenants, representations, warranties and conditions of this Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties and their respective successors, representatives and permitted assigns. No party to this Agreement may assign this Agreement, by operation of law or otherwise, in whole or in part, without the prior written consent of the other parties, and any assignment made or attempted in violation of this Section is void and of no effect.

9. No Third Party Beneficiaries. Nothing contained in this Agreement, express or implied, is intended to confer upon any Persons, other than the parties hereto or their respective successors, any rights, remedies, obligations, or liabilities under or by reason of this Agreement.

10. Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws, then (a) this Agreement is to be construed and enforced as if such illegal, invalid or unenforceable provision were not a part hereof; (b) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by such illegal, invalid or unenforceable provision or by its severance from this Agreement; and (c) there will be added automatically as a part of this Agreement a provision mutually agreed to which is similar in terms to such illegal, invalid or unenforceable provision as may be possible and still be legal, valid and enforceable.

11. Specific Performance. Each of the parties hereto acknowledges that the other parties would be irreparably damaged and would not have an adequate remedy at law for money damages if any of the covenants contained in this Agreement were not performed in accordance with its terms or otherwise were materially breached. Each of the parties hereto therefore agrees that, without the necessity of proving actual damages or posting bond or other security, the other party will be entitled to temporary and/or permanent injunction or injunctions which a court of competent jurisdiction concludes is justified to prevent breaches of such performance and to specific enforcement of such covenants in addition to any other remedy to which they may be entitled, at law or in equity.

12. Entire Agreement. This Agreement, the Merger Agreement, the Voting Agreement and the other agreements, documents, schedules and instruments signed and delivered by the parties to each other at the Closing are the full understanding of the parties, a complete allocation of risks between them and a complete and exclusive statement of the terms and conditions of their agreement relating to the subject matter hereof and supersede any and all prior agreements, whether written or oral, that may exist between the parties with respect thereto. Except as otherwise specifically provided in this Agreement, no conditions, usage of trade, course of dealing or performance, understanding or agreement purporting to modify, vary, explain or supplement the terms or conditions of this Agreement is binding unless hereafter made in writing and signed by the party to be bound, and no modification will be effected by the acknowledgment or acceptance of documents containing terms or conditions at variance with or in addition to those set forth in this Agreement.

C-4

Whenever the words “include,” “includes” or “including” are used in this Agreement, they are deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision in this Agreement.
