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, Southlake Bancshares, and Bank 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 Southlake Bancshares in exchange for shares of First Financial Stock shall be made by means of a 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 .888 shares of First Financial Stock for each share of Southlake Bancshares 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, splitup, 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 Southlake Bancshares Stock shall be exchanged will be appropriately and proportionately adjusted so that each Shareholder of Southlake Bancshares 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, splitup, 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, the exchange ratio shall be adjusted if the Market Value (as herein defined) of First Financial Stock is less than $40.00 per share, or, if the Book Value of Southlake Bancshares Stock (as herein defined) is less than $17.75 per share, as of the "MARKET VALUE DATE" which shall be the last business day of the calendar month preceding the date First Financial has received written notice that the Board of Governors of the Federal Reserve System has approved the application filed by First Financial to acquire all of the Southlake Bancshares Stock. If, as of the Market Value Date, the Market Value of First Financial Stock is less than $40.00 per share, the exchange ratio shall be adjusted by (i) multiplying the exchange ratio by a fraction, the numerator of which is $40.00 and the denominator of which is the Market Value of First Financial Stock. If, as of the Market Value Date, the Book Value of Southlake Bancshares Stock is less than $17.75 per share, the exchange ratio shall be adjusted by (ii) multiplying the exchange ratio by a fraction, the denominator of which is $17.75 and the numerator of which is the Book Value of Southlake Bancshares Stock. If, as of the Market Value Date, the Market Value of First Financial Stock is less than $40.00 per share, and if, as of the Market Value Date, the Book Value of --- Southlake Bancshares Stock is less than $17.75 per share, the exchange ratio shall be determined by multiplying the exchange ratio derived in (i) by the fraction derived in (ii). PROVIDED, HOWEVER, First Financial may terminate this Agreement in the event any adjustments 2 to the exchange ratio contemplated herein would result in the required issuance of more than 250,000 shares of First Financial Stock. As used herein, the "MARKET VALUE" of First Financial Stock shall mean the per share closing price of the First Financial Stock on the Nasdaq National Market Exchange. As used herein, the "BOOK VALUE" of Southlake Bancshares Stock shall mean the consolidated shareholders' equity of Southlake Bancshares determined in accordance with generally-accepted accounting principles ("GAAP") divided by the number of issued and outstanding shares of common stock of Southlake Bancshares; provided, that for purposes of determining the Book Value of Southlake Bancshares Stock as of the Market Value Date, as required above, the number of issued and outstanding shares of common stock of Southlake Bancshares shall include all shares of Southlake Bancshares Stock issued subsequent to the date of this Agreement as a result of the contemplated exercise of up to 30,299 outstanding stock options granted to certain officers and directors of Bank prior to the date of this Agreement, and shall further be deemed to include any such stock option which has not been exercised as of the Market Value Date. The shareholders' equity of Southlake Bancshares shall include the proceeds from the issuance of such new shares of stock and shall be deemed to include proceeds projected from the exercise of the remaining such stock options equal to the product of the number of outstanding stock options multiplied by the per share option price. 1.3. MEANS OF ACCEPTANCE OF EXCHANGE OFFER. A form of certificate and ------------------------------------- acceptance of the Exchange Offer (the "EXCHANGE FORM") shall accompany the Prospectus to be delivered to each Shareholder of Southlake Bancshares.

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 Southlake Bancshares Stock accompanying such Exchange Form. Shares of Southlake Bancshares Stock delivered by the Shareholders to the Transfer Agent pursuant to the exchange offer may not be withdrawn. If, for any reason, the Exchange Offer is terminated and the exchange of Southlake Bancshares 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. 1.4. MEANS OF CONSUMMATING THE EXCHANGE. The Transfer Agent, during the ---------------------------------- pendency of the Exchange Offer, shall notify First Financial and Southlake Bancshares daily of the number of shares of Southlake Bancshares Stock tendered for exchange under properly executed Exchange Forms.
