The Merger shall have all other effects set forth in the applicable provisions of the TBOC.

Section 1.5    Liabilities of Continuing Corporation. At the Effective Time, Continuing Corporation shall be liable for all Liabilities (as defined herein) of CBI and STXB.

Section 1.10    Modification of Structure.

4

(b)    Each share of common stock, par value $10.00 per share, of CBI (“CBI Stock”) issued and outstanding immediately prior to the Effective Time (other than any Cancelled Shares (as such term is defined herein)) shall be converted into the right to receive the following consideration (the “Merger Consideration”):

(i)    an amount of cash without interest equal to the quotient of (A) $19,164,000, subject to adjustment as provided inSection 2.2 (as adjusted, the “Aggregate Cash Consideration”), divided by (B) the aggregate of the number of shares of CBI Stock issued and outstanding immediately prior to the Effective Time (such amount, the “Per Share Cash Consideration”); and

(ii)    a number (such number, the “Exchange Ratio”), as adjusted in accordance with the terms of this Agreement, of validly issued, fully paid and nonassessable shares of STXB Common Stock equal to the quotient of (A) the Aggregate Stock Consideration divided by (B) the aggregate of the number of shares of CBI Stock issued and outstanding immediately prior to the Effective Time, rounded to the nearest ten thousandth. “Aggregate Stock Consideration” means 2,100,000 shares of STXB Common Stock (as adjusted in accordance withSection 2.2(b) orSection 9.1(e), if applicable), subject to appropriate adjustment (without duplication based on the same adjustment being provided elsewhere in this Agreement) for any stock split, reverse stock split, recapitalization, reclassification or similar transaction with respect to the then outstanding shares of STXB Common Stock declared or effected after the date of this Agreement and prior to the Closing Date (as defined herein).

(c)    All shares of CBI Stock issued and outstanding immediately prior to the Effective Time that are owned directly by STXB, CBI, CBNV or CSB (other than (i) shares held in trust accounts, managed accounts and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties and (ii) shares held, directly or indirectly, by such parties in respect of a debt previously contracted) shall be cancelled and shall cease to exist and no Merger Consideration or other consideration shall be delivered in exchange therefor (such cancelled shares, “Cancelled Shares”).

(i) “Adjusted Equity Capital” means CBI’s total consolidated equity capital, as determined in accordance with generally accepted accounting principles, consistently applied (“GAAP”), after giving effect to any unrealized gains or losses in the Securities Portfolio (as defined herein), less all intangible assets and the Final Transaction Costs (as defined below) to the extent not paid or accrued by CBI as of the Calculation Date.

5

(ii)    “Final Transaction Costs” means all Transaction Costs (as defined below), all of which shall be set forth in the Final Closing Statement (as defined herein) delivered pursuant toSection 7.6 of this Agreement.

(iii)    “Transaction Costs” means theafter-tax amount of all of the costs and expenses of KPL, CBI, CBNV or CSB incurred (or to be incurred) in connection with the transactions contemplated by this Agreement through the Closing Date (except such costs and expenses will only be reduced by the tax effect on such costs and expenses to the extent that CBI or any of its Subsidiaries is able to claim a tax deduction for such costs and expenses), including without limitation: (A) the amount of any costs, fees, expenses and commissions payable to any broker, finder, financial advisor or investment banking firm in connection with this Agreement or the transactions contemplated hereby, including, but not limited to, the CBI Advisory Fees; (B) the amount of all legal and accounting fees and other expenses incurred in connection with the negotiation, execution or performance of this Agreement or the consummation of the transactions contemplated hereby; (C) the premium or additional cost or expense incurred to obtain any additional liability insurance coverage pursuant toSection 5.6(a) or to purchase the Tail Policy (as defined herein) pursuant toSection 5.6(b); (D) the amount of any costs, fees, expenses, contract payments, penalties or liquidated damages paid or accrued in connection with the termination of Contracts to be Terminated (as defined herein) pursuant toSection 5.5; (E) the amount of any payments to be made pursuant to any existing employment, change in control, salary continuation, deferred compensation or other similar agreements or arrangements or severance, noncompetition, retention or bonus arrangements between CBI or CSB and any other Person (as defined herein) (including any “excess parachute payments” within the meaning of Section 280G of the Code or similarly applicable state law) in excess of the applicable amount accrued for any such payment in accordance with GAAP on CBI’s consolidated balance sheet in the ordinary course of business and consistent with past practices; (F) the amount of any retention or“stay-put” bonuses paid by CBI or CSB Bank to its employees at or prior to the Effective Time; (G) the amount of any costs to terminate and liquidate any CBI Employee Plan and to pay all related expenses and fees, including expenses and fees associated with any governmental filings in connection with such termination, to the extent such termination is required hereunder or requested by STXB; (H) any amount required to be added to CSB’s allowance for loan and lease losses pursuant toSection 5.7 so that such allowance equals the Minimum Allowance Amount (as defined herein) as of the date of delivery of the Final Closing Statement; (I) the amount of any costs expected to be incurred by the Continuing Corporation on or after the Closing Date to fully complete all Unresolved Response Actions pursuant toSection 5.11(c); (J) the amount of any costs and expenses incurred in connection with the sale, transfer or disposition of the Subject Loans (as defined herein) pursuant toSection 5.18; (K) an amount equal to the aggregate book value of the Subject Loans as of the Calculation Date, only if the Subject Loans have been transferred to KPL or have not been sold, transferred or disposed of on or before to the Calculation Date; (L) the amount of any costs and expenses, including legal fees and expenses and settlement costs, accrued by CBI pursuant toSection 10.1(f); and (M) such other amounts

(b)    Aggregate Stock Consideration. If the Average Closing Price (as defined below) is less than the number obtained by multiplying the Average Initial Price (as defined below) by 0.80, then the number of shares of STXB Common Stock in the Aggregate Stock Consideration will be increased such that the value of the Aggregate Stock Consideration (valuing the Aggregate Stock Consideration based on the Average Closing Price) will be equal to the product of (A) the value of 2,100,000 shares of STXB Common Stock (valuing such shares based on the Average Initial Price) multiplied by (B) 0.80;provided, however,that the number of shares of STXB Common Stock in the Aggregate Stock Consideration shall not be increased by more than 82,000 shares. If the Average Closing Price is greater than the number obtained by multiplying the Average Initial Price by 1.20, then the number of shares of STXB Common Stock in the Aggregate Stock Consideration will be decreased such that the value of the Aggregate Stock Consideration (valuing the Aggregate Stock Consideration based on the Average Closing Price) will be equal to the product of (x) the value of 2,100,000 shares of STXB Common Stock (valuing such shares based on the Average Initial Price) multiplied by (y) 1.20;provided, however,that the number of shares of STXB Common Stock in the Aggregate Stock Consideration shall not be decreased by more than 51,000 shares.

(i)    “Average Initial Price” means the average of the closing price per share of STXB Common Stock on NASDAQ for the ten (10) consecutive trading days ending on and including the trading day immediately preceding the date of this Agreement.

(ii)    “Average Closing Price” means the average of the closing price per share of STXB Common Stock on NASDAQ for the ten (10) consecutive trading days ending on and including the fifth (5th) trading day preceding the Closing Date.

Section 2.3    Deposit of Merger Consideration. Promptly after the Effective Time, STXB shall deposit with or make available to the Exchange Agent (as defined herein) for exchange in accordance withSection 2.4: (a) the Aggregate Stock Consideration and (b) immediately available funds equal to the Aggregate Cash Consideration (together with, to the extent then determinable, any cash payable in lieu of fractional shares pursuant toSection 2.4(f)) (collectively, the “Exchange Fund”), and STXB shall instruct the Exchange Agent to timely deliver the Merger Consideration.

Section 2.4    Delivery of Merger Consideration.

(a)    Computershare Trust Company, N.A. shall act as Exchange Agent on behalf of STXB (the “Exchange Agent”). At least twenty (20) days prior to the Effective Time, the Exchange Agent shall mail to KPL, as the sole holder of record of certificates (other than with respect to Cancelled Shares) representing shares of CBI Stock (each, a “Certificate”), (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)) to the Exchange Agent and shall be substantially in such form and have

7

such other provisions as shall be prescribed by the Exchange Agent Agreement (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 STXB Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant toSection 2.4(c).

(b)    If KPL surrenders to the Exchange Agent its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal at least five (5) Business Days prior to the Closing Date, then KPL will be entitled to receive the Merger Consideration and any cash in lieu of a fractional share of STXB Common 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 on the Closing Date. Otherwise, within five (5) Business Days after surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, such holder of CBI Stock will be entitled to receive the Merger Consideration and any cash in lieu of a fractional share of STXB Common 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. Until so surrendered, each Certificate (other than Certificates representing Cancelled Shares, which shall be treated as provided inSection 2.1(c)) 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 STXB Common Stock to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with thisSection 2.4, and any dividends or distributions to which such holder is entitled pursuant to thisSection 2.4.

(c)    No dividends or other distributions with respect to STXB Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of STXB Common Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with thisSection 2.4. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate in accordance with thisSection 2.4, the record holder thereof shall be entitled to receive, without interest, the amount of dividends or other distributions payable with respect to shares of STXB Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date).

(d)    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 STXB Common 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 (as defined herein) 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 STXB and the Exchange Agent that the Tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the earlier of (x) six (6) months after the Effective Time and (y) the expiration or termination of the Exchange Agent Agreement, STXB) shall be entitled to deduct and withhold from the cash portion of the Merger Consideration and any cash in lieu of a fractional share of

8

STXB Common Stock otherwise payable pursuant to this Agreement to any holder of CBI Stock such amounts as the Exchange Agent or STXB, 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 the amounts are so withheld by the Exchange Agent or STXB, as the case may be, and timely paid over to the appropriate Governmental Body (as defined herein), such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of CBI Stock in respect of whom such deduction and withholding was made by the Exchange Agent or STXB, as the case may be.

(e)    After the Effective Time, there shall be no transfers on the stock transfer books of CBI of the shares of CBI Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of CBI Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented to STXB, they shall be promptly presented to the Exchange Agent for exchange as provided in thisSection 2.4, they shall be cancelled and exchanged for the Merger Consideration and any cash in lieu of fractional shares of STXB Common Stock to be issued or paid in consideration therefor in accordance with the procedures set forth in thisSection 2.4.

(f)    Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of STXB Common Stock shall be issued upon the surrender of Certificates for exchange, no dividend or distribution with respect to STXB Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of STXB.

(g)    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 STXB. In such event, any former shareholders of CBI who have not theretofore complied with the exchange procedures in thisSection 2.4 shall thereafter look only to STXB with respect to the Merger Consideration, any cash in lieu of any fractional shares and any unpaid dividends and distributions on the STXB Common 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. Notwithstanding the foregoing, none of STXB, CBI, the Continuing Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of CBI Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(h)    In the event any Certificate shall have been lost, stolen, mutilated or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen, mutilated or destroyed and, if required by STXB or the Exchange Agent, the posting by such person of a bond in such amount as STXB or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it

9

with respect to such Certificate, STXB or the Exchange Agent, as the case may be, shall issue in exchange for such lost, stolen, mutilated or destroyed Certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

Section 2.5    Special Dividend. If the Adjusted Equity Capital set forth in the Final Closing Statement exceeds the Minimum Equity Capital, then immediately prior to the Effective Time, CBI may declare and pay to each holder of record of CBI Stock as of the record date determined by the board of directors of CBI a cash dividend for each outstanding share of CBI Stock equal to the quotient of (a) the amount that the Adjusted Equity Capital exceeds the Minimum Equity Capital, divided by (b) the total number of shares of CBI Stock outstanding as of the record date of such dividend (the “Special Dividend”).

Section 2.6    Tax Adjustment. Notwithstanding anything in this Agreement to the contrary, to preserve the status of the Merger as atax-free reorganization within the meaning of Section 368(a)(1)(A) of the Code, if the aggregate value of the shares of STXB Common Stock to be issued in connection with the Merger (excluding the value of fractional shares for which cash is to be paid pursuant toSection 2.4(f)) based upon the closing price of the STXB Common Stock as reported on NASDAQ on the trading day immediately preceding the Closing Date (the “Total Share Consideration”) would be less than forty percent (40%) of the sum of the Total Cash Consideration (defined below) and the Total Share Consideration, then the Exchange Ratio will be increased with a corresponding decrease to the Per Share Cash Consideration so that the Aggregate Stock Consideration is equal to forty percent (40%) of the sum of the Total Share Consideration and the Total Cash Consideration without changing the value of the Merger Consideration underSection 2.4(b). For purposes of this Agreement, the term “Total Cash Consideration” shall mean the sum of (i) the aggregate cash consideration to be paid in exchange for CBI Stock and (ii) the aggregate cash consideration to be paid in lieu of fractional shares of STXB Common Stock pursuant toSection 2.4(f).

(b)    Any Indemnified Party wishing to claim indemnification under thisSection 6.8, upon learning of any such claim, action, suit, proceeding or investigation, is to promptly notify STXB, but the failure to so notify will not relieve STXB of any liability it may have to the Indemnified Party to the extent such failure does not prejudice STXB.

Furthermore, if STXB, or any of its successors or assigns, shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of STXB, or the surviving company shall assume the obligations set forth in thisSection 6.8 prior to or simultaneously with the consummation of such transaction.

As a condition of transfer (other than pursuant to clauses (i), (ii) or (iii) of the preceding sentence), any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights of KPL under this Agreement and the Registration Rights Agreement, if applicable, with respect to such transferred shares of STXB Common Stock.

(b)    This Agreement may be terminated at any time prior to the Effective Time by action of the board of directors of CBI if STXB shall fail to comply in any material respect with any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of STXB contained herein shall be inaccurate in any material respect.

58

would, in the reasonable judgment of STXB, be so burdensome as to render inadvisable the consummation of the transactions contemplated by this Agreement, or (iii) any of the conditions set forth inSection 5.11(d) shall have occurred. In the event the board of directors of STXB desires to terminate this Agreement because of an alleged breach or inaccuracy as provided in clause (i) of thisSection 9.1(c), the board of directors must notify CBI in writing of its intent to terminate stating the reason therefor.
