All rights of creditors and liens upon any property of Mid-Peninsula or Cupertino shall be preserved unimpaired and all debts, liabilities and duties of Mid-Peninsula or Cupertino shall be the debts, liabilities and duties of Bancorp as the Surviving Corporation and may be enforced against it to the same extent as if such debts, liabilities and duties had been incurred or contracted by it. ARTICLE II CONVERSION OF SHARES -------------------- 2.1 Conversion of Shares. In and by virtue of the Merger and at the -------------------- Effective Time of the Merger, pursuant to this Merger Agreement, each Mid-Peninsula Share and each Cupertino Share issued and outstanding immediately prior to the Effective time of the Merger shall, at the Effective Time of the Merger, be converted. a. Effect on Mid-Peninsula Shares. At the Effective Time of the ------------------------------ Merger, each Mid-Peninsula Share issued and outstanding immediately prior to the Effective Time of the Merger shall, on and after the Effective Time of the Merger, remain issued and outstanding and shall automatically and for all purposes be deemed to represent one share of the common stock, without par value, of Bancorp as the Surviving Corporation ("Bancorp Shares"). b. Conversion of Cupertino Shares. At the Effective Time of the ------------------------------ Merger, each Cupertino Share outstanding immediately prior to the Effective Time of the Merger shall, by virtue of the Merger and without any action on the part of the holder thereof, be exchanged for 2 and converted into .81522 (the "Conversion Ratio") of a Bancorp Share. From and after the Effective Time of the Merger, each holder of Cupertino Shares immediately prior to the Effective Time of the Merger (other than holders of Dissenting Shares, as defined below) shall have the right to receive, upon surrender of the certificates theretofore representing such Cupertino Shares, one or more certificates representing shares of Bancorp Shares equal to the number of Cupertino Shares represented by each surrendered certificate multiplied by the Conversion Ratio. 2.2 Fractional Shares. No fractional Bancorp Shares shall be issued in the ----------------- Merger. In lieu thereof, each record holder of Cupertino Shares who would otherwise be entitled to receive a fractional Bancorp Share shall receive, subject to prior surrender of certificates representing Cupertino Shares, an amount in cash equal to the product (calculated to the nearest hundredth) obtained by multiplying the average of the bid and asked prices quoted by each brokerage firm acting as a market maker of Mid-Peninsula Shares for a Mid- Peninsula Share for each of the twenty (20) consecutive trading days up to and including the last business day of the calendar month end immediately prior to the Closing Date (as defined in the Agreement), by the fraction of a Bancorp Share to which such holder would otherwise be entitled. No such holder shall be entitled to dividends, voting rights, interest, or any other rights in respect of any such fractional share. 2.3 Exchange Procedures. ------------------- a. At and after the Effective Time of the Merger, Mid-Peninsula will deliver or cause to be delivered to U.S. Stock Transfer Corporation, which shall serve as exchange agent (the "Exchange Agent"), such number of blank certificates representing Bancorp Shares sufficient to issue the number of Bancorp Shares issuable in the Merger and an amount of cash sufficient for payment of any fractional shares. b. As soon as practicable after the Effective Time of the Merger, the Exchange Agent will send written notice of exchange procedures to each record holder of certificates representing Cupertino Shares converted pursuant to Section 2.1(b) of this Merger Agreement. c. Upon surrender for cancellation to the Exchange Agent of one or more certificates evidencing Cupertino Shares ("Cupertino Certificates"), accompanied by a duly executed letter of transmittal in proper form, the Exchange Agent shall promptly deliver to each holder of such surrendered Cupertino Certificates one or more new certificates representing the appropriate number of Bancorp Shares ("Bancorp Certificates") to which such holder is entitled, together with one or more checks for payment of cash in lieu of fractional interests to be issued in respect of the Cupertino Shares so surrendered. d. Until Cupertino Certificates have been surrendered and exchanged for Bancorp Certificates as herein provided, each outstanding Cupertino Certificate shall represent, on and after the Effective Time of the Merger, the right to receive the number of Bancorp Shares into which the number of Cupertino Shares shown thereon have been converted. No dividends or other distributions of any kind which are declared payable to holders of record of the Bancorp 3 Shares after the Effective Time of the Merger will be paid to persons otherwise entitled to receive the same until such persons have surrendered their Cupertino Certificates in exchange for Bancorp Certificates in the Manner herein provided, but upon such surrender, such dividends or other distributions, from and after the Effective Time of the Merger, will be paid to such persons in accordance with the terms of such Bancorp Shares. In no event shall the persons entitled to receive such dividends or other distributions be entitled to receive interest on such dividends or other distributions. e. No. transfer taxes shall be payable by any holder of Cupertino Shares in respect of the issuance of Bancorp Certificates for Bancorp Shares, except that if any Bancorp Certificate for Bancorp Shares is to be issued in a name other than that in which the Cupertino Certificate surrendered shall be been registered, it shall be a condition of such issuance that the person requesting such issuance shall properly endorse the certificate or certificates and shall pay to Bancorp any transfer taxes payable by reason thereof, or of any prior transfer of such surrendered certificate, or establish to the satisfaction of Bancorp that such taxes have been paid or are not payable. f. Any Bancorp Shares delivered to the Exchange Agent and not issued pursuant hereto at the end of one (1) year from the Effective Time of the Merger shall be returned to Bancorp, in which event the persons, if any, entitled thereto shall look only to Bancorp for payment thereof. g. Notwithstanding anything to the contrary set forth herein, if any holder of Cupertino Shares shall be unable to surrender his or her Cupertino Certificates because such certificates have been lost or destroyed, such holder may deliver in lieu thereof an indemnity bond in form and substance and with surety satisfactory to Bancorp. h. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the Bancorp Shares held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect to such Bancorp Shares for the account of the persons entitled thereto. All dividends or distributions, and any cash to be paid in lieu of fractional shares, if held by the Exchange Agent for payment or delivery to the holders of unsurrendered certificates representing Cupertino Shares and unclaimed at the end of one (1) year from the Effective Time of the Merger, shall (together with any interest earned thereon) at such time be paid or redelivered by the Exchange Agent to Bancorp, and after such time any holder of certificate representing Cupertino Shares who has not surrendered such certificate to the Exchange Agent shall, subject to applicable law, look as a general creditor only to Bancorp for payment or delivery of such dividends or distributions or cash, as the case may be. 2.4 Dissenting Shareholders. Notwithstanding the provisions of this ----------------------- Article II to the contrary, any Cupertino Shares held by persons who have satisfied the requirements of Chapter 13 of the California General Corporation Law (the "GCL") and who have not effectively withdrawn or lost their dissenters' rights under Chapter 13 (such shares being referred to as "Dissenting Shares"), shall not be converted pursuant to this Merger Agreement, but the holders 4 thereof shall be entitled only to such rights as are afforded them by Chapter 13 of the GCL.
