(hereinafter referred to as "FIRST FINANCIAL"), a Texas corporation with its principal office in the City of Abilene, Taylor County, Texas; and (2) CLEBURNE STATE BANK (hereinafter referred to as "CSB"), a state bank having its principal office in the City of Cleburne, Johnson County, Texas. RECITALS: -------- First Financial is a registered bank holding company. First Financial owns all of the issued and outstanding capital stock of First Financial Bankshares of Delaware, Inc. ("FFB DELAWARE") which, in turn, owns all of the issued and outstanding capital stock of First National Bank of Abilene; First National Bank, Sweetwater; Eastland National Bank; Hereford State Bank; First National Bank in Cleburne; Stephenville Bank & Trust Co.; San Angelo National Bank; Texas National Bank, Southlake; and Weatherford National Bank. As of the date of this Agreement, CSB has 195,740 authorized shares of Common Stock (the "CSB STOCK") having a par value of Four Dollars ($4.00) each, with 195,740 shares being issued and outstanding. According to the records of CSB, the CSB Stock is presently held by those individuals, trusts, estates, corporations and other entities (the "SHAREHOLDERS") identified in the List of Shareholders attached hereto as EXHIBIT A. --------- Pursuant to, and subject to, the provisions hereinafter set forth, First Financial desires to acquire from the Shareholders all of the issued and outstanding shares of CSB Stock in exchange for shares of the voting Common Stock of First Financial ("FIRST FINANCIAL STOCK") which shall be issued and registered by First Financial under the Securities Act of 1933, as amended (the "ACT"). NOW, THEREFORE, in consideration of the premises, and in further consideration of the mutual covenants and on the basis of the representations and warranties set forth herein, First Financial and CSB have agreed, and by these presents do hereby agree, as follows: ARTICLE 1 EXCHANGE OF STOCK 1.1. MEANS OF EXCHANGE. The offer (the "EXCHANGE OFFER") to acquire all ----------------- of the shares of CSB Stock in exchange for shares of First Financial Stock shall be made by means of an Offering Prospectus ("PROSPECTUS") to be delivered by First Financial to each of the Shareholders upon or following the effective date of a Registration Statement to be filed by First Financial in accordance with the Act (the "REGISTRATION STATEMENT"). 1.2. RATIO OF EXCHANGE. Subject to all terms and conditions of this ----------------- Agreement, First Financial shall be obligated to issue and exchange 1.75 shares of First Financial Stock for each share of CSB Stock tendered by the Shareholders who accept the Exchange Offer during the time period the Exchange Offer is in effect; PROVIDED, HOWEVER, that if, prior to consummation of the proposed Exchange Offer, a share of First Financial Stock shall be changed into a different number of shares of First Financial Stock or a different class of shares by reason of reclassification, recapitalization, split up, exchange of shares or adjustments, or if a stock dividend thereon shall be declared with a record date within such period, then the number of shares of First Financial Stock into which a share of CSB Stock shall be exchanged will be appropriately and proportionately adjusted so that each Shareholder of CSB Stock shall be entitled to receive such number of shares of First Financial Stock as such Shareholder would have received pursuant to such reclassification, recapitalization, split up, exchange of shares or adjustments, or as a result of such stock dividend, had the record date thereof been immediately following consummation of the exchange; FURTHER PROVIDED, if, the Market Value (as herein defined) of First Financial Stock is less than $40.00 per share, or greater than $44.00 per share, the exchange ratio shall be adjusted by multiplying the exchange ratio by a fraction, the numerator of which is $42.00 and the denominator of which is the Market Value of First Financial Stock. PROVIDED, HOWEVER, either First Financial or CSB may terminate this Agreement in the event any adjustments to the exchange ratio contemplated herein would result in the required issuance of more than 375,000 shares of First Financial Stock (as adjusted in the event a share of First Financial Stock shall be changed into a different number of shares by reason of reclassification, recapitalization, split up, exchange of shares or adjustments, or if a stock dividend thereon shall be declared with a record date prior to consummation of the proposed Exchange Offer). As used herein, the "MARKET VALUE" of First Financial Stock shall mean the average of the daily last sales prices of First Financial Stock reported on the NASDAQ national market system ("NASDAQ NMS")(as reported by The Wall Street Journal or, if not reported thereby, another authoritative source) for the ten (10) consecutive full trading days in which such shares are traded on the NASDAQ NMS ending at the close of trading on the tenth (10th) business day prior to the mailing of the Prospectus. 1.3. MEANS OF ACCEPTANCE OF EXCHANGE OFFER. A form of certificate and ------------------------------------- acceptance of the Exchange Offer (the "EXCHANGE FORM") in substantially the same form as EXHIBIT B, shall accompany the Prospectus to be delivered to each --------- Shareholder of CSB. The Exchange Form shall require that each Shareholder certify that the subject CSB Stock held by the Shareholder will be transferred to First Financial free and clear of all liens, restrictions, charges and encumbrances and not be subject to any adverse claim. Once the Exchange Form has been signed by a Shareholder and delivered to the Transfer Agent (as defined in Section 1.5), the same shall be deemed to constitute an acceptance of the Exchange Offer to the extent of the number of shares of CSB Stock accompanying such Exchange Form. Shares of CSB Stock delivered by the Shareholders to the Transfer Agent pursuant to the Exchange Offer may not be withdrawn, except as provided by the Williams Act. If, for any reason, the Exchange Offer is terminated and the exchange of CSB Stock for First Financial Stock is not consummated, then all shares tendered by the Shareholders for exchange shall be promptly returned by the Transfer Agent. 2 1.4. MEANS OF CONSUMMATING THE EXCHANGE. The Transfer Agent, during the ---------------------------------- pendency of the Exchange Offer, shall notify First Financial and CSB, in writing, daily of the number of shares of CSB Stock tendered for exchange under properly executed Exchange Forms. If First Financial receives written notice from the Transfer Agent that the Required Amount of CSB Stock (as defined in Section 2.2) has been tendered and assigned to First Financial, then, within ten (10) days after the Closing Date, First Financial shall issue and mail to those Shareholders who have tendered their shares of CSB Stock, by registered mail, certificates for the First Financial Stock representing the number of whole shares of First Financial's stock as required under Section 1.2 above for each share of CSB Stock received by the Transfer Agent. For purposes of this Agreement, the "CLOSING DATE" shall be the later of (i) the date First Financial ----- receives notice from the Transfer Agent that the Required Amount of CSB Stock has been tendered, (ii) the expiration date of the Exchange Offer, or (iii) the date when all conditions precedent to consummation of the exchange have been satisfied (or, if not satisfied, have been waived in writing by First Financial or CSB, as the case may be, in accordance with Section 1.9). Subject to the terms and conditions of this Agreement, the exchanges called for by this Agreement will be effective as of the Closing Date. Notwithstanding the foregoing provisions of this Section and of Section 1.3, First Financial shall not issue any fractional shares of its Common Stock. Shareholders of CSB who would otherwise be entitled to receive fractional shares of First Financial Stock shall be paid in cash for such fractional shares based upon the Market Value per share of First Financial Stock . Any cash payment to which a Shareholder of CSB may be entitled shall be included with such Shareholder's certificate for First Financial Stock when such certificate is mailed to such Shareholder. 1.5. TRANSFER AGENT. The Transfer Agent (herein so called) for purposes -------------- of this transaction shall be First National Bank of Abilene - Trust Department, Third Floor, 400 Pine Street, Abilene, Texas 79601. 1.6. EFFECTIVE DATE OF EXCHANGE OFFER. The effective date for -------------------------------- commencement of the Exchange Offer (the "EFFECTIVE DATE") contemplated by this Agreement shall be the later of: (a) The date upon which the Prospectus is mailed by First Financial to the Shareholders of CSB pursuant to the Registration Statement (not before but on or following the effective date thereof) filed by First Financial with the Securities and Exchange Commission ("SEC") with respect to the First Financial Stock to be issued hereunder; or (b) Such other date as may be mutually agreed upon by First Financial and CSB. 1.7.

If the Exchange Offer is consummated, but less than all of the CSB Stock is tendered in exchange for First Financial Stock, then as part of the proposed merger of CSB into First National Bank in Cleburne, those Shareholders of CSB who did not tender their shares pursuant to the Exchange Offer made under this Agreement will be required to accept cash payment for their shares determined upon the same basis as the exchange of CSB Stock for First Financial Stock, subject only to the rights, if any, afforded by applicable law to any Shareholders of CSB who dissent from the merger and refuse to accept the cash payment tendered in return for their CSB Stock. 1.9.
