The number of shares of Common Stock that may be received upon the exercise of the Option and the Option Price are subject to adjustment as herein set forth. (b) ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. In the event that any additional shares of Common Stock are issued or otherwise become outstanding after the date of this Agreement (other than pursuant to this Agreement), the number of shares of Common Stock subject to the Option shall be increased so that, after such issuance, it equals 19.9% of the number of shares of Common Stock then issued and outstanding without giving effect to any shares subject or issued pursuant to the Option. Nothing contained in this Section 2(b) or elsewhere in this Agreement shall be deemed to authorize Issuer or Grantee to breach any provision of the Merger Agreement. 3. EXERCISE OF OPTION. (a) PRECONDITIONS TO EXERCISE. The Holder (as defined in Section 1(e)) may exercise the Option, in whole or part, and from time to time (but not more than an aggregate of three times), if, but only if, both an Initial Triggering Event (as defined in Section 1(f)) and a Subsequent Triggering Event (as defined in Section 1(j)) shall have occurred prior to the occurrence of an Exercise Termination Event (as defined in Section 1(d)); PROVIDED that the Holder shall have sent the written notice of such exercise (as provided in Section 3(c)) within 50 days following such Subsequent Triggering Event. (b) NOTIFICATION BY ISSUER AS TO CERTAIN EVENTS. Issuer shall notify Grantee promptly in writing of the occurrence of any Initial Triggering Event or Subsequent Triggering Event (together, a "Triggering Event"), it being understood that the giving of such notice by Issuer shall not be a condition to the right of the Holder to exercise the Option. (c) NOTICE OF EXERCISE OF OPTION. In the event the Holder is entitled to and wishes to exercise the Option, it shall send to Issuer a written notice (the date of which being herein referred to as the "Notice Date") specifying (i) the total number of shares it will purchase pursuant to such exercise and (ii) a place and date not earlier than three business days nor later than 20 business days from the Notice Date for the closing of such purchase (the "Closing Date"); provided that if prior notification to or approval of the Federal Reserve Board or any other regulatory agency is required in connection with such purchase, the Holder shall promptly file the required notice or application for approval and shall expeditiously process the same and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods (including any extensions thereof) have expired or been terminated or such approvals have been obtained and any requisite waiting period or periods (including any extensions thereof) shall have passed. Any exercise of the Option shall be deemed to occur on the Notice Date relating thereto. (d) PAYMENT OF EXERCISE PRICE. At the closing referred to in Section 3(c), the Holder shall pay to Issuer the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank 4 account designated by Issuer, provided that failure or refusal of Issuer to designate such a bank account shall not preclude the Holder from exercising the Option. (e) DELIVERY OF CERTIFICATES. At such closing, simultaneously with the delivery of immediately available funds as provided in Section 3(d), Issuer shall deliver to the Holder a certificate or certificates representing the number of shares of Common Stock purchased by the Holder and, if the Option should be exercised in part only, a new Option evidencing the rights of the Holder thereof to purchase the balance of the shares purchasable hereunder, and the Holder shall deliver to Issuer a copy of this Agreement and a letter agreeing that the Holder will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement. (f) RESTRICTIVE LEGEND. Certificates for Common Stock delivered at a closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows: "The transfer of the shares represented by this certificate is subject to certain provisions of an agreement between the registered holder hereof and Issuer and to resale restrictions arising under the Securities Act of 1933, as amended. A copy of such agreement is on file at the principal office of Issuer and will be provided to the holder hereof without charge upon receipt by Issuer of a written request therefor." It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the Holder shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares have been sold or transferred in compliance with the provisions of this Agreement and under circumstances that do not require the retention of such reference; and (iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) are both satisfied. In addition, such certificates shall bear any other legend as may be required by law. (g) HOLDER OF RECORD. Upon the giving by the Holder to Issuer of the written notice of exercise of the Option provided for under Section 3(c) and the tender of the applicable purchase price in immediately available funds, the Holder shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to the Holder. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges imposed upon Issuer that may be payable in connection with the preparation, issue and delivery of stock certificates under this Section 3 in the name of the Holder or its permitted assignee. 4. CERTAIN AGREEMENTS OF THE ISSUER. Issuer agrees: (i) that it shall at all times maintain, free from preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock so that the Option may be exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights to 5 purchase Common Stock; (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act, avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all action as may from time to time be required (including (x) complying with all premerger notification, reporting and waiting period requirements specified in 15 U.S.C. sec. 18a and regulations promulgated thereunder and (y) in the event, under the Bank Holding Company Act of 1956, as amended (the "BHCA"), or the Change in Bank Control Act of 1978, as amended, or any state banking law, prior approval of or notice to the Federal Reserve Board or to any other federal or state regulatory authority is necessary before the Option may be exercised, cooperating fully with the Holder in preparing such applications or notices and providing such information to the Federal Reserve Board or such other federal or state regulatory authority as they may require) in order to permit the Holder to exercise the Option and Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly to take all action provided herein to protect the rights of the Holder against dilution. 5. SURRENDER AND EXCHANGE. Subject to the provisions of Section 12, this Agreement (and the Option granted hereby) are exchangeable, without expense, at the option of the Holder, upon presentation and surrender of this Agreement at the principal office of Issuer, for other Agreements providing for Options of different denominations entitling the holder thereof to purchase, on the same terms and subject to the same conditions as are set forth herein, in the aggregate the same number of shares of Common Stock purchasable hereunder. The terms "Agreement" and "Option" as used herein include any Stock Option Agreements and related Options for which this Agreement (and the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date. Any such new Agreement executed and delivered shall constitute an additional contractual obligation on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated shall at any time be enforceable by anyone. 6. FURTHER ADJUSTMENT IN NUMBER OF SHARES PURCHASABLE. In addition to the adjustment in the number of shares of Common Stock that are purchasable upon exercise of the Option pursuant to Section 2(b) of this Agreement, the number of shares of Common Stock purchasable upon the exercise of the Option and the Option Price shall be subject to adjustment from time to time as provided in this Section 6. In the event of any change in, or distributions in respect of, the Common Stock by reason of stock dividends, split-ups, mergers, recapitalization, combinations, subdivisions, conversions, exchanges of shares, distributions on or in respect of the Common Stock (whether or not the same would be prohibited under the terms of the Merger Agreement), or the like, the type and number of shares of Common Stock purchasable upon exercise hereof and the Option Price shall be appropriately adjusted in such manner as shall fully preserve the economic benefits provided hereunder and proper provision shall be made in any agreement governing any such transaction to provide for such proper adjustment and the full satisfaction of the Issuer's obligations hereunder. 6 7. REGISTRATION. The obligations set forth in this Section 7 shall apply during such time as securities of the Issuer (or its successors or assigns) are registered under the 1934 Act. Upon the occurrence of a Subsequent Triggering Event that occurs prior to an Exercise Termination Event, Issuer shall, at the request of Grantee delivered within 50 day after such Subsequent Triggering Event (whether on its own behalf or on behalf of any subsequent holder of this Option (or part thereof) or any of the shares of Common Stock issued pursuant hereto), promptly prepare, file and keep current a shelf registration statement under the 1933 Act covering the resale of this Option and any shares issued pursuant to this Option and the issuance of any shares issuable pursuant to this Option to the extent then permitted under the rules, regulations or policies of the SEC and, to the extent not so permitted, the resale of such shares issuable pursuant to this Option. The Issuer shall use its reasonable best efforts to cause such registration statement to become effective and remain current in order to permit the sale or other disposition of this Option and any shares of Common Stock issued upon total or partial exercise of this Option ("Option Shares") in accordance with any plan of disposition requested by Grantee. Issuer will use its reasonable best efforts to cause such registration statement first to become effective and then to remain effective for such period not in excess of 180 days from the day such registration statement first becomes effective or such longer time as may be reasonably necessary to effect such sales or other dispositions. Grantee shall have the right to demand two such registrations. The foregoing notwithstanding, if, at the time of any request by Grantee for registration of the Option or Option Shares as provided above, Issuer is in registration with respect to an underwritten public offering of shares of Common Stock, and if in the good faith judgment of the managing underwriter or managing underwriters, or, if none, the sole underwriter or underwriters, of such offering, the inclusion of the Holder's Option or Option Shares would interfere with the successful marketing of the shares of Common Stock offered by Issuer, the number of Option Shares otherwise to be covered in the registration statement contemplated hereby may be reduced; and PROVIDED, HOWEVER, that after any such required reduction the number of Option Shares to be included in such offering for the account of the Holder shall constitute at least 25% of the total number of shares to be sold by the Holder and Issuer in the aggregate; and PROVIDED FURTHER, HOWEVER, that if such reduction occurs, then the Issuer shall file a registration statement for the balance as promptly as practical and no reduction shall thereafter occur. Each such Holder shall provide all information reasonably requested by Issuer for inclusion in any registration statement to be filed hereunder. If requested by any such Holder in connection with such registration, Issuer shall become a party to any underwriting agreement relating to the sale of such shares, but only to the extent of obligating itself in respect of representations, warranties, indemnities and other agreements customarily included in such underwriting agreements for the Issuer. Upon receiving any request under this Section 7 from any Holder, Issuer agrees to send a copy thereof to any other person known to Issuer to be entitled to registration rights under this Section 7, in each case by promptly mailing the same, postage prepaid, to the address of record of the persons entitled to receive such copies. Notwithstanding anything to the contrary contained herein, in no event shall Issuer be obligated to effect more than two registrations pursuant to this Section 7 by reason of the fact that there shall be more than one Grantee as a result of any assignment or division of this Agreement. 8. SUBSTITUTE OPTION. (a) In the event that prior to an Exercise Termination Event, Issuer shall enter into an agreement (i) to consolidate with or merge into any person, other than Grantee or one of its 7 Subsidiaries, and shall not be the continuing or surviving corporation of such consolidation or merger, (ii) to permit any person, other than Grantee or one of its Subsidiaries, to merge into Issuer and Issuer shall be the continuing or surviving corporation, but, in connection with such merger, the then outstanding shares of Common Stock shall be changed into or exchanged for stock or other securities of any other person or cash or any other property or the then outstanding shares of Common Stock shall after such merger represent less than 50% of the outstanding voting shares and voting share equivalents of the merged company, or (iii) to sell or otherwise transfer all or substantially all of its assets to any person, other than Grantee or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction shall make proper provision so that the Option shall, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option (the "Substitute Option"), at the election of the Holder, of either (x) the Acquiring Corporation (as hereinafter defined) or (y) any person that controls the Acquiring Corporation. (b) The following terms have the meanings indicated: (1) "Acquiring Corporation" shall mean (i) the continuing or surviving corporation of a consolidation or merger with Issuer (if other than Issuer), (ii) Issuer in a merger in which Issuer is the continuing or surviving person, and (iii) the transferee of all or substantially all of Issuer's assets. (2) "Substitute Common Stock" shall mean the common stock issued by the issuer of the Substitute Option upon exercise of the Substitute Option. (3) "Assigned Value" shall mean the market/offer price, as defined in Section 1(h). (4) "Average Price" shall mean the average closing price of a share of the Substitute Common Stock for the one year immediately preceding the consolidation, merger or sale in question, but in no event higher than the closing price of the shares of Substitute Common Stock on the day preceding such consolidation, merger or sale; provided that if Issuer is the issuer of the Substitute Option, the Average Price shall be computed with respect to a share of common stock issued by the person merging into Issuer or by any company which controls or is controlled by such person, as the Holder may elect. (c) The Substitute Option shall have the same terms as the Option, provided, that if the terms of the Substitute Option cannot, for legal reasons, be the same as the Option, such terms shall be as similar as possible and in no event less advantageous to the Holder. The issuer of the Substitute Option shall also enter into an agreement with the then Holder or Holders of the Substitute Option in substantially the same form as this Agreement, which shall be applicable to the Substitute Option. (d) The Substitute Option shall be exercisable for such number of shares of Substitute Common Stock as is equal to the Assigned Value multiplied by the number of shares of Common Stock for which the Option is then exercisable, divided by the Average Price. The exercise price of the Substitute Option per share of Substitute Common Stock shall then be equal to the Option 8 Price multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock for which the Option is then exercisable and the denominator of which shall be the number of shares of Substitute Common Stock for which the Substitute Option is exercisable. (e) In no event, pursuant to any of the foregoing provisions of this Section 8, shall the Substitute Option be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise of the Substitute Option. In the event that the Substitute Option would be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise but for this clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer") shall make a cash payment to Holder equal to the excess of (i) the value of the Substitute Option without giving effect to the limitation in this clause (e) over (ii) the value of the Substitute Option after giving effect to the limitation in this clause (e). This difference in value shall be determined by a nationally recognized investment banking firm selected by the Holder, and reasonably acceptable to the Acquiring Corporation. (f) Issuer shall not enter into any transaction described in Section 8(a) unless the Acquiring Corporation and any person that controls the Acquiring Corporation assume in writing all the obligations of Issuer hereunder. 9. EXTENSION OF TIME. The 50-day period for exercise of certain rights under Sections 3, 7 and 12 shall be extended: (i) to the extent necessary to obtain all regulatory approvals for the exercise of such rights, and for the expiration of all statutory waiting periods; and (ii) to the extent necessary to avoid liability under Section 16(b) of the 1934 Act by reason of such exercise. 10. REPRESENTATIONS AND WARRANTIES OF ISSUER. Issuer hereby represents and warrants to Grantee as follows: (a) Issuer has full corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized by the Board of Directors of Issuer and no other corporate proceedings on the part of Issuer are necessary to authorize this Agreement or to consummate the transactions so contemplated. This Agreement has been duly and validly executed and delivered by Issuer. (b) Issuer has taken all necessary corporate action to authorize and reserve and to permit it to issue, and at all times from the date hereof through the termination of this Agreement in accordance with its terms will have reserved for issuance upon the exercise of the Option, that number of shares of Common Stock equal to the maximum number of shares of Common Stock at any time and from time to time issuable hereunder, and all such shares, upon issuance pursuant hereto, will be duly authorized, validly issued, fully paid, nonassessable, and will be delivered free and clear of all claims, liens, encumbrance and security interests and not subject to any preemptive rights. 11. REPRESENTATIONS AND WARRANTIES OF GRANTEE. Grantee hereby represents and warrants to Issuer that: 9 (a) Grantee has all requisite corporate power and authority to enter into this Agreement and, subject to any approvals or consents referred to herein, to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Grantee. This Agreement has been duly executed and delivered by Grantee. (b) The Option is not being, and any shares of Common Stock or other securities acquired by Grantee upon exercise of the Option will not be, acquired with a view to the public distribution thereof and will not be transferred or otherwise disposed of except in a transaction registered or exempt from registration under the Securities Act. 12. NO ASSIGNMENT. Neither of the parties hereto may assign any of its rights or obligations under this Option Agreement or the Option created hereunder to any other person, without the express written consent of the other party, except Grantee may assign the Option to an affiliate or in connection with a merger in which it is not the surviving entity or in connection with a sale of all or substantially all of its assets. 13. REASONABLE BEST EFFORTS. Each of Grantee and Issuer will use its best efforts to make all filings with, and to obtain consents of, all third parties and governmental authorities necessary to the consummation of the transactions contemplated by this Agreement, including without limitation making application to list the shares of Common Stock issuable hereunder on the NASDAQ National Stock Market upon official notice of issuance and applying to the Federal Reserve Board under the BHCA for approval to acquire the shares issuable hereunder. 14. SPECIFIC PERFORMANCE. The parties hereto acknowledge that damages would be an inadequate remedy for a breach of this Agreement by either party hereto and that the obligations of the parties hereto shall be enforceable by either party hereto through injunctive or other equitable relief. 15. SEVERABILITY.

If for any reason such court or regulatory agency determines that the Holder is not permitted to acquire the full number of shares of Common Stock provided in Section 2(a) hereof (as adjusted pursuant to Section 2(b) or 6 hereof), it is the express intention of Issuer to allow the Holder to acquire such lesser number of shares as may be permissible, without any amendment or modification hereof. 16. NOTICES.
