Western shall set aside, in cash out of the Adjusted Cash Component, for each Perfected Dissenting Share the Adjusted Per Share Merger Consideration (the “Dissenters’ Set Aside”).

(b) The holders of certificates formerly representing shares of Auburn Common Stock shall cease to have any rights as shareholders of Auburn, except such rights, if any, as they may have pursuant to the California Corporations Code.

If the elections of all of the Stock Electors cannot be fulfilled, then the Adjusted Stock Component shall be divided among the Stock Electors pro rata by the number of shares of their Auburn Common Stock, and each Stock Elector shall receive cash from the Remaining Adjusted Cash Component for the remainder of the Per Share Merger Consideration for each share of Auburn Common Stock which is not converted into shares of Western Common Stock and all other shareholders will only receive cash.

If there are any shares of Western Common Stock remaining from the Adjusted Stock Component after payment to the Stock Electors, then each Cash/Stock Elector shall receive for each share of Auburn Common Stock he or she owns the Per Share Merger Consideration in shares of Western Common Stock. In the event there are insufficient shares of Western Common Stock available to pay all the Cash/Stock Electors in full with shares of Western Common Stock, then the left over Adjusted Stock Component shall be divided among the Cash/Stock Electors pro rata by the number of shares of their Auburn Common Stock and each such Cash/Stock Elector shall receive cash from the Remaining Adjusted Cash Component for the remainder of the Per Share Merger Consideration for each share of Auburn Common Stock which is not converted into shares of Western Common Stock and all other shareholders will only receive cash.

If there are any shares of Western Common Stock remaining after payment to the Stock Electors and Cash/Stock Electors, then, each holder of Auburn Common Stock other than a holder of Perfected Dissenting Shares that makes no election or an improper election (“No Election Shareholder”) shall receive for each share of Auburn Common Stock he or she owns the Per Share Merger Consideration in shares of Western Common Stock. In the event there are insufficient shares of Western Common Stock available to pay all the No Election Shareholders in full with shares of Western Common Stock, then the left over Adjusted Stock Component shall be divided among the No Election Shareholders pro rata by the number of shares of their Auburn Common Stock and each such No Election Shareholder shall receive cash from the Remaining Adjusted Cash Component for the remainder of the Per Share Merger Consideration for each share of Auburn Common Stock which is not converted into shares of Western Common Stock and all other shareholders will only receive cash.

(d) An Auburn shareholder may not make a Cash/Stock Election until after the Effective Time and need not make a Cash/Stock Election at all. Promptly following the Effective Time, Western shall send to each Auburn shareholder a letter of transmittal describing the Cash/Stock Election in more detail and providing forms for making the Cash/Stock Election, as desired.

(e) The Cash/Stock Election, if made, must be made by the Auburn shareholder and received by the Exchange Agent within 30 calendar days following the Effective Time (the “Election Deadline”) for all shares held in the name of the Auburn shareholder (the “Effective Election Statement”). An Auburn shareholder who holds shares in two or more capacities or in different names may make a separate Cash/Stock Election for each name or capacity in which shares are held. However, holders whose shares are represented by one or more certificates may make only one Cash/Stock Election for each such certificate.

(f) Auburn shareholders who make Cash/Stock Elections have no assurance that they will receive all cash or all stock or any specific proportion thereof.

2.6.4 Exchange of Auburn Common Stock.

(a) As soon as reasonably practicable after the Effective Time, holders of record of certificates formerly representing shares of Auburn Common Stock (“Certificates”) shall be instructed to tender such Certificates to the Exchange Agent pursuant to a letter of transmittal that Western shall deliver or cause to be delivered to such holders. Such letter of transmittal shall specify that risk of loss and title to Certificates shall pass only upon acceptance of such Certificates by Western or the Exchange Agent.

(b) After the Effective Time, each holder of a Certificate that surrenders such Certificate to Western or the Exchange Agent will, upon acceptance thereof by Western or the Exchange Agent, be entitled to the Per Share Merger Consideration payable in respect of the shares represented thereby as determined under Section 2.6.2.

(c) Western or the Exchange Agent shall accept Certificates upon compliance with such reasonable terms and conditions as Western or the Exchange Agent may impose to effect an orderly exchange thereof in accordance with customary exchange practices. Certificates shall be appropriately endorsed or accompanied by such instruments of transfer as Western or the Exchange Agent may reasonably require.

(d) Each outstanding Certificate, other than those representing Perfected Dissenting Shares, shall until duly surrendered to Western or the Exchange Agent be deemed to evidence the right to receive the Per Share Merger Consideration payable in respect of the shares represented thereby.

(e) After the Effective Time, holders of Certificates shall cease to have rights with respect to the Auburn Common Stock previously represented by such Certificates, and their sole rights (other than the holders of Certificates representing Perfected Dissenting Shares) shall be to exchange such Certificates for the Per Share Merger Consideration. At the Effective Time, Auburn shall deliver a certified copy of a list of its shareholders to Western or the Exchange Agent. After the Effective Time, there shall be no further transfer of Certificates on the records of Auburn, and if such Certificates are presented to Auburn for transfer, they shall be canceled against delivery of the Per Share Merger Consideration. Western shall not be obligated to deliver any Per Share Merger Consideration to any holder of Auburn Common Stock until such holder surrenders the Certificates as

provided herein. No dividends declared will be remitted, nor any voting rights granted, to any person entitled to receive Western Common Stock under this Agreement until such person surrenders the Certificate representing the right to receive such Western Common Stock, at which time such dividends on whole shares of Western Common Stock with a record date on or after the Effective Time shall be remitted to such person, without interest and less any taxes that may have been imposed thereon, and voting rights will be restored. Certificates surrendered for exchange by any person constituting an “affiliate” of Auburn for purposes of Rule 145 under the Securities Act of 1933 and the rules and regulations thereunder (the “Securities Act”) shall not be exchanged for certificates representing Western Common Stock until Western has received a written agreement from such person as specified in Section 5.3. Neither the Exchange Agent nor any party to this Agreement nor any affiliate thereof shall be liable to any holder of Auburn Common Stock represented by any Certificate for any consideration paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Western and the Exchange Agent shall be entitled to rely upon the stock transfer books of Auburn to establish the identity of those persons entitled to receive consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Certificate, Western or the Exchange Agent shall be entitled to deposit any consideration in respect thereof in escrow with an independent third party and thereafter be relieved with respect to any claims thereto.

(f) If any Per Share Merger Consideration is to be issued to a person other than a person in whose name a surrendered Certificate is registered, it shall be a condition of issuance that the surrendered Certificate shall be properly endorsed or otherwise in proper form for transfer and that the person requesting such issuance shall pay to Western or the Exchange Agent any required transfer or other taxes or establish to the satisfaction of Western or the Exchange Agent that such tax has been paid or is not applicable.

(g) In the event any Certificate shall have been lost, stolen or destroyed, the owner of such lost, stolen or destroyed Certificate shall deliver to Western or the Exchange Agent an affidavit stating such fact, in form satisfactory to Western, and, at Western’s discretion, a bond in such reasonable sum as Western or the Exchange Agent may direct as indemnity against any claim that may be made against Western or Auburn or its successor or any other party with respect to the Certificate alleged to have been lost, stolen or destroyed. Upon such delivery, the owner shall have the right to receive the Per Share Merger Consideration with respect to the shares represented by the lost, stolen or destroyed Certificate.

2.6.5 No Fractional Shares. Notwithstanding any other provision of this Agreement, neither certificates nor scrip for fractional shares of Western Common Stock shall be issued in the Merger. Each holder who otherwise would have been entitled to a fraction of a share of Western Common Stock (after taking into account all Certificates of such holder) shall receive in lieu thereof cash (without interest) in an amount determined by multiplying the fractional share interest to which such holder would otherwise be entitled by the Average Closing Price. No such holder shall be entitled to dividends, voting rights or any other rights in respect of any fractional share interest.

2.7 Dissenters’ Rights. Shares of Auburn Common Stock, the holders of which have lawfully dissented from the Merger in accordance with Chapter 13 of the California Corporations Code (“Chapter 13”) and have timely filed with Auburn a written demand for purchase of his or her shares and have surrendered his or her stock certificates pursuant to Section 1302 of Chapter 13, are herein called “Dissenting Shares.” Dissenting Shares, the holders of which have not effectively withdrawn or lost their dissenters’ rights under Chapter 13 (“Perfected Dissenting Shares”), shall not be converted pursuant to Section 2.6 but the holders thereof shall be entitled only to such rights as are granted by Chapter 13. Each holder of Perfected Dissenting Shares who is entitled to payment for his or her Auburn Common Stock pursuant to the provisions of Chapter 13 shall receive payment therefor from Western (but only after the amount thereof shall have been agreed upon or finally determined pursuant to such provisions).

If any holder of Dissenting Shares has effectively withdrawn or lost his or her dissenter’s rights under Chapter 13 prior to the Election Deadline, an Effective Election Statement submitted with respect to such shares will be given effect in the same manner as other Effective Election Statements but if no Effective Election Statement is submitted, such shares will be treated as No Election Shares.

Auburn’s Board of Directors will recommend to its shareholders approval of this Agreement, the Merger Agreement and the Merger; provided, however, that Auburn’s Board of Directors may withdraw its recommendation if such Board of Directors believes in good faith (based on a written opinion of a financial advisor that is experienced in evaluating the fairness of Acquisition Proposals) that an Auburn Superior Proposal (defined below) has been made and shall have determined in good faith, after consultation with and based on written advice of its outside legal counsel, that the withdrawal of such recommendation is necessary for such Board of Directors to comply with its fiduciary duties under applicable law.

6.3.4 Duly and timely file as and when due all reports and Returns required to be filed with any Governmental Entity;

6.3.5 File all necessary applications with the Federal Reserve and the CDFI for the transaction as soon as possible, but no later than October 31, 2003 and furnish to Auburn, as soon as practicable, and in any event within fifteen days after it has prepared all applications to be submitted to the Federal Reserve and CDFI for approval of the Merger; and
