Any shares of Company Common Stock held directly or indirectly by Placer, the Company or any of their respective Subsidiaries, other than those held in a fiduciary capacity or as a result of indebtedness previously contracted (“Treasury Shares”), shall automatically be cancelled and retired and shall cease to exist at the Effective Time of the Merger and no consideration shall be issued in exchange therefor.

3.03. No Fractional Shares.

No holder will be entitled to dividends, voting rights or any other rights as a shareholder in respect of any fractional share of Placer Common Stock.

3.04. Exchange Procedures. (a) Exchange Agent. At or prior to the Effective Time, Placer shall deposit, or cause to be deposited, with the Exchange Agent, for the benefit of the holders of Shares, certificates representing the number of shares of Placer Common Stock issuable in the Merger and funds in an amount not less than the amount of cash payable in lieu of fractional shares of Company Common Stock which would otherwise be issuable in connection with Section 3.01 hereof but for the operation of Section 3.03 of this Agreement (the “Exchange Fund”), it being understood that any and all interest or income earned on funds made available to the Exchange Agent pursuant to this Agreement shall be turned over to Placer. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to Placer Common Stock 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 shares for the account of the Persons entitled thereto in accordance with Section 3.04(e).

(b) Exchange of Certificates. As soon as practicable after the Effective Time, but in no event later than the tenth Business Day thereafter, Placer shall cause the Exchange Agent to mail to each former holder of record of Shares (i) a letter of transmittal specifying that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or customary affidavits and indemnification regarding the loss or destruction of such Certificates in accordance with Section 3.04(g)), in such form and substance as designated by Placer and reasonably acceptable to the Company, and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Each holder of a Certificate who surrenders or has surrendered such Certificate, together with a duly executed transmittal letter, to the Exchange Agent shall, upon acceptance thereof, be entitled to a certificate representing Placer Common Stock, as well as cash in lieu of any fractional shares of Placer Common Stock pursuant to Section 3.03 and any dividends or other distributions pursuant to Section 3.04(e) (in each case after giving effect to any required Tax deductions and withholdings in accordance with Section 3.04(h)), and any Certificates so surrendered shall automatically be cancelled and retired and shall cease to exist. The Exchange Agent shall accept Certificates upon compliance with such reasonable and customary terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal practices. Until surrendered as contemplated by this Section 3.04(b), each Certificate shall be deemed from and after the Effective Time to evidence only the right to receive the Merger Consideration (including any cash in lieu of any fractional share and unpaid dividends or distributions on Placer Common Stock) upon surrender thereof. Placer shall not be obligated to deliver the Merger Consideration (or any cash in lieu of any fractional share or unpaid dividends or distributions on Placer Common Stock) to which any former holder of Shares is entitled as a result of the Merger until such holder surrenders his Certificate or Certificates for exchange as provided in this Article III. If any certificate representing shares of Placer Common Stock, or any check representing cash and/or declared but unpaid dividends, is to be issued in a name other than that in which a Certificate surrendered for exchange is issued, the Certificate so surrendered shall be accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable Taxes have been paid. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates.

(c) Affiliates. Certificates surrendered for exchange by any Person constituting an “affiliate” of the Company for purposes of Rule 145 under the Securities Act shall not be exchanged for certificates representing shares of Placer Common Stock until Placer has received a written agreement from such Person in the form of Exhibit E hereto (an “Affiliate Agreement”).

(d) No Liability. Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto shall be liable to any former holder of Shares for any amount properly delivered to a Governmental Authority pursuant to applicable abandoned property, escheat or similar laws.

(e) Voting and Dividends. Former shareholders of record of the Company shall not be entitled to vote after the Effective Time of the Merger at any meeting of Placer shareholders

until such holders have exchanged their Certificates for certificates representing Placer Common Stock in accordance with the provisions of this Agreement. Until surrendered for exchange in accordance with the provisions of Section 3.04(b), each Certificate shall from and after the Effective Time of the Merger represent for all purposes only the right to receive the Merger Consideration (including any cash in lieu of any fractional share and unpaid dividends or distributions on Placer Common Stock). No dividends or other distributions declared or made after the Effective Time with respect to Placer Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Placer Common Stock represented thereby until the holder of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate for which shares of Placer Common Stock are to be issued, there shall be paid to the holder of such Certificate without interest, (i) the amount of any cash payable with respect to a fractional share of Placer Common Stock to which such holder is entitled pursuant to Section 3.03, (ii) the amount of dividends or other distributions with a record date after the Effective Time of the Merger theretofore paid with respect to whole shares of Placer Common Stock and (iii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and a payment date subsequent to the surrender of such Certificate payable with respect to whole shares of Placer Common Stock.

(f) Unclaimed Portion of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by holders of Shares for 180 days after the Effective Time shall be paid, in the case of cash, and returned, in the case of certificates representing shares of Placer Common Stock, to Placer. Any holders of Shares who have not theretofore complied with this Article III shall thereafter look only to Placer for the Merger Consideration (including any cash in lieu of any fractional shares and unpaid dividends or distributions on Placer Common Stock) deliverable in respect of their Shares upon due surrender of their Certificates (or customary affidavits and indemnification regarding the loss or destruction of such Certificates in accordance with Section 3.04(g)) pursuant to this Article III, in each case, without any interest thereon.

(g) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Placer or the Exchange Agent, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue and pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration (including any cash in lieu of any fractional share and unpaid dividends or distributions on Placer Common Stock) deliverable in respect of Shares represented by such Certificate.

(h) Withholding Rights. Placer or the Exchange Agent shall be entitled to deduct and withhold from any cash in lieu of any fractional share and unpaid dividends or distributions on Placer Common Stock otherwise payable pursuant to this Agreement to any holder of Shares such amounts as Placer or the Exchange Agent are required to deduct and withhold with respect to the making of such payment under the Code, or any provision of federal, state, local or foreign tax law. To the extent that amounts are so deducted and withheld by Placer or the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding was made by Placer or the Exchange Agent.

3.05. Anti-Dilution Provisions.

If, between the date hereof and the Effective Time, Placer shall merge with, be acquired by or consolidate into any other Person (each, a “Business Combination”) and the terms thereof shall provide that Placer Common Stock shall be converted into or exchanged for the capital stock or assets of any other Person, then provision shall be made as part of the terms of such Business Combination so that holders of Shares shall be entitled to receive, in lieu of each share of Placer Common Stock issuable to such holders as provided herein, the same kind and amount of capital stock or assets as shall be distributable upon such Business Combination with respect to one share of Placer Common Stock (provided that nothing herein shall be construed so as to release the acquiring entity in any such Business Combination from its obligations under this Agreement as the successor to Placer).

(ii) Has all permits, licenses, franchises, variances, exemptions, certificates of authority, orders, authorizations, consents and approvals of, and has made all filings, applications, notices and registrations with, all Governmental Authorities that are required in order to permit it to own or lease its assets and properties and to conduct its business as presently conducted, except for those that are not, individually or in the aggregate, reasonably likely to have a Placer Material Adverse Effect or prevent, materially delay or materially impair the ability of Placer or any of its Subsidiaries to consummate the transactions contemplated by this Agreement; all such permits, licenses, franchises, variances, exemptions, certificates of authority, orders, authorizations, consents and approvals are in full force and effect and, to Placer’s or its Subsidiaries’ Knowledge, no suspension or cancellation of any of them is threatened.

(iii) No investigation or review by any Governmental Authority with respect to Placer or any of its Subsidiaries is pending or, to Placer’s or any of its Subsidiaries’ Knowledge, threatened, nor has Placer or any of its Subsidiaries received any notification or communication from any Governmental Authority (A) asserting that Placer or PSB, as the case may be, is not in compliance with any of the Laws which such Governmental Authority enforces or (B) threatening to revoke any license, franchise, permit or governmental authorization (nor, to Placer’s or any of its Subsidiaries’ Knowledge, do any grounds for any of the foregoing exist).

Subject to the terms and conditions of this Agreement, each of the Company and Placer agrees to cooperate with the other and use its reasonable efforts in good faith to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable on its part under this Agreement or under applicable laws to consummate and make effective the Merger and the other transactions contemplated hereby as promptly as practicable, including the satisfaction of the conditions set forth in Article VII hereof.

6.02. Shareholder Consent. If considered necessary or appropriate by Placer, the Company shall give, or cause to be given, in accordance with § 603(b) of the CGCL notice of the Shareholder Consent to the holders of Company Common Stock (other than the California Fund).

6.03. Press Releases. The Company and Placer shall consult with each other before issuing any press release with respect to the Merger or this Agreement and shall not issue any such press release or make any such public statements without the prior consent of the other party, which consent shall not be unreasonably withheld or delayed; provided, however, that a party may, without the prior consent of the other party (but after such consultation, to the extent practicable in the circumstances), issue such press release or make such public statements as may upon the advice of outside counsel be required by law or the rules or regulations of Nasdaq or the SEC. The Company and Placer shall cooperate to develop all public announcement materials and make appropriate management available at presentations related to the transactions contemplated by this Agreement as reasonably requested by the other party.

6.04. Access; Information. (a) The Company agrees that upon reasonable notice and subject to applicable laws relating to the exchange of information, it shall afford Placer and Placer’s officers, employees, counsel, accountants and other authorized representatives reasonable access during normal business hours throughout the period prior to the Effective Time to the books, records (including, without limitation, Tax Returns and work papers of independent auditors), Contracts, properties and personnel of the Company and its Subsidiaries and to such other information as Placer may reasonably request and, during such period, it shall furnish promptly to Placer all information concerning the business, properties and personnel of the Company and its Subsidiaries as Placer may reasonably request.

(b) Without limiting the generality of Section 6.04(a), prior to the Effective Time, Placer and Placer’s representatives shall have the right to conduct a review to determine (i) that the assets, books, records and operations of the Company and its Subsidiaries are in satisfactory condition and will not in a material way adversely impact Placer after consummation of the transactions contemplated hereby and (ii) the accuracy of the representations and warranties and the satisfaction of the conditions to closing as provided hereunder.

(c) The Company agrees that, subject to applicable laws, it shall cooperate in good faith with Placer on mutually agreed operating issues which the parties agree have priority.

6.05. Certain Policies. Immediately prior to the Effective Time, the Company and BOC shall, consistent with GAAP, the rules and regulations of the FRB and the FDIC,

respectively, and applicable banking laws and regulations (which shall govern in the event of any inconsistency with the rules and regulations of the FRB and the FDIC, as the case may be), modify or change their respective loan, OREO, accrual, reserve, Tax, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of Placer and PSB, as the case may be; provided, however, that unless the modification or changes would otherwise be necessary to be consistent with applicable law, rule or regulation or with regulatory accounting principles or GAAP, no such modification or change shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred, or as an admission or acknowledgement by the Company that any such modification or change is appropriate or required or that any financial statement or information previously provided by the Company was incorrect in any respect.

6.06. Regulatory Applications. (a) Each of Placer and the Company shall cooperate and use their respective reasonable efforts to prepare and file, or cause to be filed, all documentation to effect all necessary notices, reports and other filings and to obtain all permits, consents, approvals and authorizations necessary or advisable to be obtained from any third parties and/or Governmental Authorities in order to consummate the Merger or any of the other transactions contemplated hereby (including, without limitation, the permits, consents, exemptions, approvals and authorizations set forth in Sections 5.02(f), 5.03(b) and 5.03(f); and any initial filings with Governmental Authorities shall be made by Placer as soon as reasonably practicable after the execution hereof but, provided that the Company has cooperated as described above, in no event later than 60 days after the date hereof. Subject to applicable laws relating to the exchange of information, each of Placer and the Company shall have the right to review in advance, and to the extent practicable each shall consult with the other on, all material written information submitted to any third party and/or any Governmental Authority in connection with the Merger and the other transactions contemplated by this Agreement. In exercising the foregoing right, each of such parties agrees to act reasonably and as promptly as practicable. Each party hereto agrees that it shall consult with the other party hereto with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and/or Governmental Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each party shall keep the other party apprised of the status of material matters relating to completion of the transactions contemplated hereby (including promptly furnishing the other with copies of notices or other communications received by Placer or the Company, as the case may be, from any third party and/or Governmental Authority with respect to the Merger and other transactions contemplated by this Agreement).

(b) Each party agrees, upon request, to furnish the other party with all information concerning itself, its Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with any filing, notice or application made by or on behalf of such other party to any third party and/or Governmental Authority.

6.07. Indemnification; Director’s and Officer’s Insurance. (a) From and after the Effective Time, Placer agrees that it will indemnify and hold harmless each present and former

director and officer of the Company and BOC (each, an “Indemnified Party” and, collectively, the “Indemnified Parties”) against all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement), whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent that the Company or BOC would have been obligated under the CGCL and the Company Articles or the BOC Articles and the Company Bylaws or the BOC Bylaws in effect on the date hereof to indemnify such Person (and Placer shall also advance expenses as incurred to the fullest extent required under applicable law, provided, the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification); provided, further, that any determination required to be made with respect to whether an officer’s or director’s conduct complies with the standards set forth under the CGCL and the Company Articles or BOC Articles and the Company Bylaws or BOC Bylaws shall be made by the Board of Directors of Placer with the advice of independent counsel selected by Placer. Placer’s obligations under this Section 6.07(a) shall continue in full force and effect for a period of three (3) years from the Effective Time; provided, however, that all rights to indemnification in respect of any claim asserted or made within such period shall continue until the final disposition of such claim.

(b) Any Indemnified Party wishing to claim indemnification under paragraph (a) of this Section 6.07, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Placer thereof, but the failure to so notify shall not relieve Placer of any liability it may have to such Indemnified Party if such failure does not materially prejudice Placer. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) Placer shall have the right to assume the defense thereof and Placer shall not be liable to such Indemnified Party for any legal expenses or other counsel or any other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof, (ii) the Indemnified Party will cooperate in the defense of any such matter and (iii) Placer shall not be liable for any settlement effected without its prior written consent; provided, further, that Placer shall not have any obligation hereunder to any Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable law.

(c) For a period of three (3) years from the Effective Time, Placer shall use its commercially reasonable efforts to provide that portion of director’s and officer’s liability insurance (“D&O Insurance”) that serves to reimburse the present and former officers and directors (determined as of the Effective Time) of the Company and BOC (as opposed to the portion that serves to reimburse the Company or BOC) with respect to claims against such directors and officers arising from facts or events which occurred before the Effective Time, which D&O Insurance shall contain at least the same coverage and amounts, and contain terms and conditions no less advantageous, as that coverage provided by the Company and/or BOC as of the date hereof; provided, however, that in no event shall Placer be required to expend on an

annual basis more than 150% of the last annual premium paid prior to the date hereof (the “Insurance Cap”) to maintain or procure such D&O Insurance; provided, further, that if Placer is unable to maintain or obtain the D&O Insurance called for by this Section 6.07, Placer shall use its commercially reasonable efforts to obtain as much comparable insurance as is available for the Insurance Cap; provided, further, that officers and directors of the Company and BOC may be required to make application and provide customary representations and warranties to Placer’s insurance carrier for the purpose of obtaining such D&O Insurance.

(d) If Placer or any of its successors or assigns shall (i) consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any other Person, then, and in each case, proper provision shall be made so that the successors and assigns of Placer shall assume the obligations set forth in this Section 6.07.

6.08. Benefit Plans. (a) From and after the Effective Time, Placer agrees that any former employees of the Company or any of its Subsidiaries who continue employment with Placer or any of its Subsidiaries will be eligible to participate in the employee benefit plans of Placer or any such Subsidiary on substantially the same terms and conditions of similarly situated employees of Placer or such Subsidiary. Placer will cause such employee benefit plans to take into account for purposes of eligibility and vesting thereunder service by such employees with the Company or any of its Subsidiaries as if such service were with Placer or any such Subsidiary, as the case may be, to the same extent that such service was credited under a comparable plan of the Company or any such Subsidiary. Nothing herein shall limit the ability of Placer or any of its Subsidiaries to amend or terminate any of the Benefit Plans in accordance with their terms at any time.

(b) If any of the Company’s or its Subsidiaries’ employees become eligible to participate in a medical, dental or health plan of Placer or any of its Subsidiaries, Placer or any such Subsidiary shall use commercially reasonable efforts to cause, to the extent practicable, each such plan to (i) waive any preexisting condition limitations to the extent such conditions were covered under the applicable medical, dental or health plans of the Company or its Subsidiary, (ii) honor under such plans any deductible, co-payment and out-of-pocket expenses incurred by such employees and their beneficiaries during the portion of the calendar year prior to such participation and (iii) waive any waiting period limitation or evidence of insurability requirement which would otherwise be applicable to such employee on or after the Effective Time to the extent such employee had satisfied any similar limitation or requirement under an analogous plan prior to the Effective Time.

(c) If Placer determines that one or more Benefit Plans of the Company or any of its Subsidiaries should be amended, modified or terminated prior to the Effective Time, the Company shall take, or cause to be taken, all actions reasonably requested by Placer to so amend, modify or terminate and, if reasonably necessary or appropriate, obtain applicable determination letters or other required approvals from the IRS and/or the Department of Labor, as appropriate, in connection with such action.

(d) To the extent not taken by the Company or any of its Subsidiaries prior to the Effective Time, Placer shall use its commercially reasonable efforts to remove all officers and employees of the Company or any of its Subsidiaries from all of their respective positions with respect to any Benefit Plans of the Company or any of its Subsidiaries.

6.09. Notification of Certain Matters. Each of the Company and Placer shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in a Company Material Adverse Effect or Placer Material Adverse Effect, as the case may be, or to prevent, materially delay or materially impair the ability of the Company any of its Subsidiaries or Placer, as the case may be, to consummate the transactions contemplated by this Agreement or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein.

6.10. Human Resources Issues. The Company will, and will cause its Subsidiaries to, consult in good faith with Placer regarding the nature and content of any formal presentation of the transactions contemplated by this Agreement to employees of the Company or such Subsidiary and will include a Placer representative in any such presentation or any formal meeting at which the transaction is explained or discussed, under an arrangement that is mutually satisfactory to both parties. The Company agrees to work in good faith with Placer to facilitate the timely and accurate dissemination of information to employees regarding matters related to the transactions contemplated by this Agreement in such a manner as to cause minimal disruption of the business of the Company and its Subsidiaries and their relationships with their employees and to facilitate the transition of such relationships to Placer or its Subsidiaries, as the case may be.

6.11. Third-Party Agreements. (a) The Company shall use its commercially reasonable efforts to obtain, or cause its Subsidiaries to obtain, (i) within 45 calendar days after the date of this Agreement, the consents or waivers listed in Schedule 5.02(k) or otherwise required to be obtained from any third-parties in connection with the Merger and the transactions contemplated hereby (in such form and content as is approved in writing by Placer) and (ii) the cooperation of such third parties to effect a smooth transition in accordance with Placer’s timetable at or after the Effective Time. The Company shall cooperate with Placer in minimizing the extent to which any Contracts will continue in effect following the Effective Time, in addition to complying with the prohibitions in Section 4.01(l).

(b) Without limiting the generality of Section 6.11(a), the Company shall use all commercially reasonable efforts to provide, or cause its Subsidiaries to provide, data processing, item processing and other processing support or outside contractors to assist Placer in performing all tasks reasonably required to result in a successful conversion of the Company’s and its Subsidiaries’ data and other files and records to Placer’s production environment, when requested by Placer and in such a manner sufficient to result in a successful conversion at the time (on or after the Effective Time) designated by Placer. Among other things, the Company shall:

(i) cooperate with Placer to establish a mutually agreeable project plan to effectuate the conversion;

(ii) use their commercially reasonable efforts to have the Company’s or its Subsidiaries’ outside contractors continue to support both the conversion effort and its on-going needs until the conversion can be established;

(iii) provide, or use its commercially reasonable efforts to obtain from any outside contractors, all data or other files and layouts requested by Placer for use in planning the conversion, as soon as reasonably practicable;

(iv) provide reasonable access to the Company’s and its Subsidiaries’ personnel and facilities and, with the consent of its outside contractors, its outside contractors’ personnel and facilities, to enable the conversion effort to be completed on schedule; and

(v) give notice of termination, conditioned upon the completion of the transactions contemplated by this Section 6.11(b), of the Contracts of outside data, item and other processing contractors or other third-party vendors when directed to do so by Placer.

(c) Placer agrees that all actions taken pursuant to this Section 6.11 shall be taken in a manner intended to minimize disruption to the customary business activities of the Company and its Subsidiaries.

6.14. Pre-Closing Adjustments. At or before the Effective Time, the Company shall make, and shall cause its Subsidiaries to make, such accounting entries or adjustments, including additions to its ALL and charge-offs of loans, as Placer shall direct as a result of its on-going review of the Company and its Subsidiaries (including its review of the information provided to it pursuant to Sections 6.04 and 6.10) or in order to implement its plans following the Effective Time or to reflect expenses and costs related to the Merger; provided, however, that unless the adjustment would otherwise be required by applicable law, rule or regulation, or by regulatory accounting principles or GAAP applied on a basis consistent with the financial statements of the Company and its Subsidiaries, (a) the Company shall not be required to take, or cause to be taken, such actions more than one day prior to the Effective Time or prior to the time Placer agrees in writing that all of the conditions to its obligation to close as set forth in Section 7.03

have been satisfied or waived and each of the approvals in Section 7.01(b) have been received, and (b) no such adjustment shall (i) require any filing with any Governmental Authority, (ii) violate any law, rule or regulation applicable to the Company or any of its Subsidiaries, as the case may be, (iii) otherwise materially disadvantage the Company or any of its Subsidiaries if the Merger is not consummated or (iv) constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred.

6.15. Company Stock Options. (a) At and as of the Effective Time, Placer shall assume each and every outstanding Company Stock Option as, and solely to the extent, set forth in Schedule 5.02(b) of the Disclosure Schedule as updated pursuant to Section 7.03(b) hereof, and all obligations of the Company under the Company Stock Option Plan with respect to such assumed Company Stock Options. Each and every Company Stock Option so assumed by Placer under this Agreement shall continue to have, and be subject to, the same terms and conditions set forth in the Company Stock Option Plan and in the other documents governing such Company Stock Option immediately prior to the Effective Time, except that: (i) such Company Stock Option shall be exercisable for that number of whole shares of Placer Common Stock equal to the product of (A) the number of shares of Company Stock that were purchasable under such Company Stock Option immediately prior to the Effective Time as set forth in Schedule 5.02(b) of the Disclosure Schedule as updated pursuant to Section 7.03(b) hereof, multiplied by (B) the Conversion Ratio, with such product rounded down to the nearest whole number of shares of Placer Common Stock; and (ii) the per share exercise price for the shares of Placer Common Stock issuable upon exercise of such Company Stock Option shall be equal to the quotient determined by dividing (A) the exercise price per share of Company Common Stock at which such Company Stock Option was exercisable immediately prior to the Effective Time as set forth in Schedule 5.02(b) of the Disclosure Schedule as updated pursuant to Section 7.03(b) hereof by (B) the Conversion Ratio. As soon as reasonably practicable after the Effective Time, Placer shall issue to each holder of an outstanding Company Stock Option a document evidencing the assumption of such Company Stock Option pursuant to this Section 6.15.

and, where appropriate, file any and all agreements and other documents necessary or desirable to permit the consummation of the Bank Merger immediately following consummation of the Merger; and (iii) take and cause to be taken any other action to permit the consummation of any transactions contemplated in connection with the Bank Merger. Neither the Company nor BOC shall take any action that would prevent performance of the agreement of merger relating to the Bank Merger or any other transactions contemplated in connection with the Bank Merger.

6.18. Covenant Relating to the Tax Status of the Agreement. Placer and the Company intend that the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Code, and the parties hereto hereby adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations. Each party will both before and after the Effective Time (i) use reasonable efforts to cause this Agreement to so qualify; (ii) refrain from taking any action that would reasonably be expected to cause this Agreement to fail to so qualify; and (iii) take the position on all Tax Returns and in any communications with any taxing authority for all purposes that this Agreement so qualifies.

6.19. Redemption of Minority Interest in BOC. The Company shall use its best efforts to exchange (for no additional consideration) the fractional share of common stock of Placer Sierra Bank owned by it for the fractional share of common stock of BOC owned by Placer Sierra Bancshares.

6.21. Shareholder Approval. In the event the Shareholder Consent, or any subsequent written consent executed by the California Fund approving the principal terms of the Merger, is invalid or unenforceable in accordance with its terms under applicable Law, the Company agrees to take, if directed by Placer to do so, all action necessary to convene as soon as practicable (but in no event later than 40 days thereafter) a special meeting of its shareholders to consider and vote upon the approval of the principal terms of the Merger and any other matters required to be approved by the Company’s shareholders for consummation of the Merger. Except with the prior written approval of Placer, no other matters shall be submitted for the approval of the Company shareholders at any such special meeting.

6.22. Registration Statement; Joint Proxy Statement/Prospectus. At Placer’s request or as required by law:

(a) For the purposes of (i) registering the issuance of Placer Common Stock to holders of the shares of Company Common Stock in connection with the Merger with the SEC under the Securities Act and complying with applicable Blue Sky Laws, the Company will cooperate in the preparation of a registration statement on Form S-4 relating to the Merger (together with any and all amendments and supplements to such registration statement, the “S-4 Registration Statement”). The S-4 Registration Statement shall include a joint proxy statement/prospectus satisfying all requirements of the Securities Act, the Exchange Act and applicable Blue Sky Laws. Such joint proxy statement/prospectus in the form mailed by Placer and the Company to their respective stockholders, together with any and all amendments or supplements thereto, are herein referred to as the “Joint Proxy Statement/Prospectus.”

(b) The Company will furnish Placer with such information concerning it and its Subsidiaries as is necessary in order to cause the Joint Proxy Statement/Prospectus, insofar as it relates to the Company and its Subsidiaries, to comply with applicable Law. The Company agrees to promptly advise Placer if, at any time prior to the Merger, any information provided by it in the Joint Proxy Statement/Prospectus is or becomes incorrect or incomplete in any material respect and to provide Placer with the information needed to correct such inaccuracy or omission. The Company will furnish Placer with such supplemental information as may be necessary in order to cause the Joint Proxy Statement/Prospectus, insofar as it relates to the Company and its Subsidiaries, to comply with applicable Law after the mailing thereof to the stockholders of the Company and Placer.

(c) Placer will include in the Joint Proxy Statement/Prospectus such information concerning Placer and its Subsidiaries as is necessary in order to cause such Joint Proxy Statement/Prospectus, insofar as it relates to Placer and its Subsidiaries, to comply with applicable Law. If, at any time prior to the Merger, any information included or incorporated by reference by Placer in the Joint Proxy Statement/Prospectus is or becomes incorrect or incomplete in any material respect, Placer shall correct such inaccuracy or omission. Placer will furnish such supplemental information as may be necessary in order to cause the Joint Proxy Statement/Prospectus, insofar as it relates to Placer and its Subsidiaries, to comply with applicable Law after the mailing thereof to the stockholders of Placer and the Company.

(d) The Company and Placer agree to cooperate in making any preliminary filings of the Joint Proxy Statement/Prospectus with the SEC, as promptly as practicable, pursuant to Rule 14a-6 under the Securities Exchange Act, and shall cooperate in responding to any comments with respect thereto received from the SEC.

(e) Placer will file the S-4 Registration Statement with the SEC and appropriate materials with applicable state securities agencies as promptly as practicable and will use all reasonable efforts to cause the S-4 Registration Statement to become effective under the Securities Act and all such state filed materials to comply with applicable Blue Sky Laws. The Company authorizes Placer to utilize in the S-4Registration Statement and the Joint Proxy Statement/Prospectus and all such state filed materials, the information concerning the Company and its Subsidiaries provided to Placer in connection with, or contained or incorporated by reference in, the Joint Proxy Statement/Prospectus. Placer will promptly advise the Company when the S-4 Registration Statement has become effective and of any supplements or amendments thereto, and Placer will furnish the Company with copies of all such documents. Except for the Joint Proxy Statement/Prospectus or the preliminary joint proxy statement/prospectus, neither Placer nor the Company shall distribute any written material that might constitute a “prospectus” relating to the Merger within the meaning of the Securities Act or any applicable state securities Law without the prior written consent of the other.

(f) Each of the Company and Placer shall mail the Joint Proxy Statement/Prospectus to its stockholders as promptly as practicable after the date the S-4 Registration Statement is declared effective under the Securities Act.

(b) Regulatory Approvals. All notices, reports and other filings required to be made prior to the Effective Time by the Company or Placer or any of their respective Subsidiaries with, and all consents, registrations, approvals, permits and authorizations required to be obtained prior to the Effective Time by the Company or Placer or any of their respective Subsidiaries from, any Governmental Authority in connection with the execution, delivery and performance of this Agreement and the consummation of the Merger and the other transactions contemplated hereby, shall have been made or obtained (as the case may be) and shall remain in full force and effect and all statutory waiting periods in respect thereof shall have expired and no such approvals shall contain any conditions, restrictions or requirements which the Placer Board reasonably determines in good faith would (i) following the Effective Time, have a Placer Material Adverse Effect or (ii) reduce the benefits of the transactions contemplated hereby to such a degree that Placer would not have entered into this Agreement had such conditions, restrictions or requirements been known as of the date hereof.

(c) No Injunction. No Governmental Authority of competent jurisdiction shall have enacted, issued, promulgated, enforced or entered any statute, law, ordinance, rule, regulation, judgment, decree, injunction or other order (whether temporary, preliminary or permanent) that is in effect and restrains, enjoins or otherwise prohibits consummation of the transactions contemplated by this Agreement (collectively, an “Order”).

(d) Tax Opinion. Placer and the Company shall have received an opinion of counsel from counsel to Placer in the form reasonably satisfactory to Placer to the effect that on the basis of certain facts, representations, and opinions set forth in such opinion that the Merger will qualify as a reorganization under Section 368(a) of the Code.

(b) Performance of Obligations of Placer. Placer and its Subsidiaries shall have performed in all material respects all obligations required to be performed by them under this Agreement at or prior to the Effective Time, and the Company shall have received a certificate signed by an executive officer of Placer, dated as of the Effective Time, to such effect.

The representations and warranties of the Company set forth in this Agreement shall be true and correct as of the date of this Agreement and as of the Effective Time as though made on and as of the Effective Time (except that representations and warranties that by their terms speak as of the date of this Agreement or some other date shall be true and correct as of such date) and Placer shall have received a certificate signed on behalf of the Company by the Chief Executive Officer and Chief Financial Officer of the Company, dated as of the Effective Time, to such effect. For purposes of this paragraph, such representations and warranties shall be deemed to be true and correct unless the failure or failures of such representations and warranties to be true and correct in all material respects, either individually or in the aggregate, and without giving effect to any materiality, material adverse effect or similar qualifications set forth in such representations and warranties, will have or would reasonably be expected to have a Company Material Adverse Effect or prevent, materially delay or materially impair the ability of the Company or any of its Subsidiaries to consummate the transactions contemplated by this Agreement.

(b) Updated Disclosure Schedule. The Disclosure Schedule shall be updated and made current as of the day prior to the Effective Time of the Merger and a draft of the updated Disclosure Schedule shall have been delivered to Placer no later than 72 hours prior to the

Effective Time; such update of the Disclosure Schedule shall not in any way affect the representations and warranties set forth in Section 5.02. In its sole and absolute discretion, Placer shall be satisfied with any matter reflected, listed or disclosed in the updated Disclosure Schedule that was not reflected, listed or disclosed on the original Disclosure Schedule.

(c) Performance of Obligations of Company. The Company and its Subsidiaries shall have performed in all material respects all obligations required to be performed by them under this Agreement at or prior to the Effective Time, and Placer shall have received a certificate signed on behalf of the Company by the Chief Executive Officer and the Chief Financial Officer of the Company, dated as of the Effective Time, to such effect.

(d) Performance of Obligations of the Shareholder. Placer shall have received the Shareholder Agreement and, if requested by Placer or required by Law, the Shareholder Consent executed and delivered by the California Fund as contemplated by Section 6.12, each of which shall remain in full force and effect. The California Fund shall have performed in all material respects all obligations required to be performed by it under the Shareholder Agreement.

(e) Shareholders’ Equity and Reserves. As of June 30, 2004 (the “Shareholders’ Equity Measuring Date”), (i) the Adjusted Shareholders’ Equity of the Company shall not be less than $58,000,000 and (ii) the Company’s ALL shall not be less than $5,000,000, inclusive of the amount of the reserve for unfunded loan commitments, in each case as determined in accordance with GAAP. For purposes of this Section 7.03(e), “Adjusted Shareholders’ Equity” means the equity of the Company as of June 30, 2004, excluding any gains or losses on or changes in fair market value of securities of the Company from such calculation, and adding the sum of, without duplication, (w) all amounts paid or accrued in connection with any actions taken pursuant to Sections 6.05 and 6.15 to the extent that such actions were not necessary to bring the Company into conformity with GAAP or any applicable rule or regulation of any Governmental Authority, (x) all fees and expenses of all attorneys, accountants, investment bankers and other advisors and agents for the Company (“Advisors”) for services rendered solely in connection with the transactions contemplated by this Agreement (collectively, “Professional Fees”) paid by the Company prior to the Effective Time and which do not exceed in the aggregate $400,000.00 (exclusive of reasonable costs incurred or advanced by such Advisors and excluding any fees and expenses of such Advisors incurred by the Company at Placer’s written request) (y) amounts accrued or to be accrued by the Company for severance payments to be made pursuant to agreements or policies in effect on the date hereof in contemplation of the consummation of the transactions provided for hereby and (z) the aggregate amount paid by the Company, if any, in order to satisfy its obligation to take all action as may be necessary to cancel the Company Stock Options pursuant to Section 6.16.

(f) No Litigation. No Governmental Authority or any other Person shall have instituted any proceeding or threatened to institute any proceeding seeking any Order. In addition, following the execution of this Agreement by Placer, legal counsel to Placer shall not have received any information in connection with any litigation, action, suit or proceeding to which the Company or BOC is subject that is deemed to be material and adverse by such legal counsel (within its sole discretion).

(g) Closing Financial Statements. At least four Business Days prior to the Effective Time, the Company shall provide Placer with the Company’s consolidated financial statements presenting the financial condition of the Company and its Subsidiaries as of the close of business on the last day of the last month ended prior to the Effective Time and the Company’s and its Subsidiaries’ results of operations for the period January 1, 2004 through the close of business on the last day of the last month ended prior to the Effective Time (the “Closing Financial Statements”); provided, however, that if the Effective Time occurs on or before the fifth Business Day of the month, the Company shall have provided consolidated financial statements as of and through the second month preceding the Effective Time of the Merger. Such financial statements shall have been prepared in all material respects in accordance with GAAP and regulatory accounting principles and other applicable legal and accounting requirements, and reflect all period-end accruals and other adjustments. Such financial statements shall be accompanied by a certificate of the Company’s Chief Financial Officer, dated as of the Effective Time, to the foregoing effect and to the effect that such financial statements continue to reflect accurately, as of the date of the certificate, the financial condition of the Company and its Subsidiaries, on a consolidated basis, in all material respects.

(h) Consents. The Company shall have obtained each of the consents listed in Schedule 5.02(k) of the Disclosure Schedule and any consents of the type required to be identified in Schedule 5.02(k) of the Disclosure Schedule but which were not so identified as of the date of this Agreement. A copy of each such consent shall have been delivered to Placer.

(i) Transaction Expenses. The Company shall have used its reasonable efforts to cause its Advisors to submit final bills or estimates of final bills for all Professional Fees to the Company at least two Business Days prior to the Effective Time. Based upon such final bills or estimates of such final bills, the Company shall have paid all Professional Fees in full prior to the Effective Time, and Placer shall have received written evidence from the Company to such effect prior to the Effective Time; provided, that Placer shall have been given a reasonable opportunity to review and comment on all invoices, bills and estimates relating to such Professional Fees prior to their payment; provided, further, that the aggregate amount of such Professional Fees shall be reasonable and shall in no event exceed $400,000.00 (exclusive of reasonable costs incurred or advanced by its Advisors). In no event shall Placer be liable for any such Professional Fees or for any amounts payable to the Company’s or its Subsidiaries’ Advisors.

(k) Dissenting Shareholders. At the Effective Time, the Company shall have complied with its obligations and duties under Chapter 13 of the CGCL, if any, with respect to the rights of Dissenting Shareholders, including, without limitation, the provision of the notice to holders required pursuant to § 1301 of the CGCL.

(l) S-4 Registration. If requested by Placer or required by Law, the S-4 Registration Statement shall have become effective under the Securities Act, no stop order suspending its effectiveness shall be in effect and no proceeding for such purpose shall have been initiated or threatened by or before the SEC. All state securities and “blue sky” permits or approvals necessary or appropriate to consummate the Merger shall have been received and remain in effect.

8.01. Termination by Mutual Consent. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time by the mutual written consent of Placer and the Company by action of their respective boards of directors.

8.02. Termination by Either Placer or the Company. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time by action of the board of directors of either Placer or the Company, in the event:

(a) The Merger is not consummated by September 30, 2004, except to the extent that the failure of the Merger then to be consummated arises out of or results from the knowing action or inaction of (i) the party seeking to terminate pursuant to this Section 8.02(a), (ii) the California Fund (if the Company is the party seeking to terminate), which action or inaction is in violation of its obligations under this Agreement or, in the case of the California Fund, its obligations under the Shareholder Agreement.

(b) The approval of any Governmental Authority required for consummation of the Merger and the other transactions contemplated by this Agreement shall have been denied by final and nonappealable action of such Governmental Authority or an application therefor shall have been permanently withdrawn at the invitation, request or suggestion of a Governmental Authority.

8.03. Termination by the Company. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time by action of the Company Board if:

(a) There has been a breach of any representation, warranty, covenant or agreement made by Placer in this Agreement, or any such representation and warranty shall have become untrue after the date of this Agreement, such that Sections 7.02(a) or 7.02(b) would not be satisfied and such breach or condition is not curable or, if curable, is not cured within 30 days after written notice thereof is given by the Company to Placer.

8.04. Termination by Placer. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time by action of the Placer Board if:

(a) There has been a breach of any representation, warranty, covenant or agreement made by the Company in this Agreement, or any such representation and warranty shall have become untrue after the date of this Agreement, such that Sections 7.03(a) or 7.03(c) would not be satisfied and such breach or condition is not curable or, if curable, is not cured within 30 days after written notice thereof is given by Placer to the Company.

(b) There is a material breach by the California Fund of any of the representations, warranties, covenants or agreements contained in the Shareholder Agreement, which breach cannot be or has not been cured within 30 days after written notice thereof is given by Placer to the California Fund.

8.05. Effect of Termination and Abandonment. (a) In the event of termination of this Agreement and the abandonment of the Merger pursuant to this Article VIII, this Agreement (other than as set forth in Section 9.01) shall become void and of no effect with no liability or further obligation on the part of any party hereto (or of any of its directors, officers, employees, agents, legal and financial advisors or other representatives); provided, however, except as otherwise provided herein, no such termination shall relieve any party hereto of any liability or damages resulting from any willful breach of this Agreement.

9.01. Survival. This Article IX, the agreements of the Company and Placer contained in Sections 6.07, 6.08, 6.11 and 6.18 shall survive the consummation of the Merger. This Article IX and the agreements of the Company and Placer contained in the Mutual NDA and Section 8.05 shall survive the termination of this Agreement. The Shareholder Agreement shall survive the consummation of the Merger and the termination of this Agreement. All other representations, warranties, covenants and agreements in this Agreement shall not survive the consummation of the Merger or the termination of this Agreement.

9.02. Waiver; Amendment. Prior to the Effective Time, any provision of this Agreement may be (i) waived in whole or in part by the party benefited by the provision or by both parties or (ii) amended or modified at any time by an agreement in writing between the parties hereto executed in the same manner as this Agreement; provided, however, that no such amendment or modification shall reduce the aggregate value of the Merger Consideration to be received by the Company’s shareholders in the Merger without any subsequent approval by such shareholders or be in violation of applicable law.

9.03. Counterparts. This Agreement may be executed in one or more counterparts (including by facsimile), each of which shall be deemed to constitute an original, but all of which together shall constitute one and the same instrument.

9.04. Governing Law and Venue; Waiver of Jury Trial; Attorneys’ Fees. (a) This Agreement shall be deemed to be made in and in all respects shall be interpreted, construed and governed by and in accordance with the laws of the State of California, without regard to the conflict of law principles thereof. The parties hereby irrevocably submit to the jurisdiction and venue of the courts located in Sacramento, California, of the State of California and the federal courts of the United States of America located in the Northern District of the State of California solely in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby and thereby, and hereby waive, and agree not to assert, as a defense in any action, suit or

proceeding for the interpretation or enforcement hereof or of any such documents, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such California state or federal court. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.06 or in such other manner as may be permitted by law, shall be valid and sufficient service thereof.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.04.

(c) In the event that the waiver of jury trial set forth in this Agreement is held to be unenforceable, the parties agree that any and all claims or disputes arising from, relating to or in connection with this Agreement, or the Merger contemplated hereby, shall be resolved by binding arbitration by the American Arbitration Association in Sacramento, California, pursuant to its Commercial Arbitration Rules.

(d) If a party commences an action or proceeding against another party arising from, relating to or in connection with this Agreement, the losing party shall pay to the prevailing party its reasonable attorney’s fees, costs and expenses, court costs and other costs of action incurred in connection with the prosecution or defense of such action, whether or not the action is prosecuted to a final judgment, including, without limitation, all such fees and expenses incurred with respect to litigation, appeals, mediations, arbitrations and other similar proceedings.

9.05. Expenses. Unless otherwise provided in this Agreement, whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the Merger and the other transactions contemplated by this Agreement shall be paid by the party incurring such expense.

9.06. Notices. All notices, requests, instructions and other communications to be given hereunder by any party to the other shall be in writing and shall be deemed given if personally delivered, telecopied (with confirmation) or mailed by registered or certified mail, postage prepaid (return receipt requested), to such party at its address set forth below or such other address as such party may specify by notice to the other party.

9.07. Entire Understanding; No Third Party Beneficiaries. This Agreement (including the Disclosure Schedule attached hereto and incorporated herein), the Mutual NDA, the

Shareholder Agreement and, if requested by Placer or required by Law, the Shareholder Consent constitute the entire agreement of the parties hereto and thereto with reference to the transactions contemplated hereby and thereby and supersede all other prior agreements, understandings, representations and warranties, both written and oral, between the parties or their officers, directors, agents, employees or representatives, with respect to the subject matter hereof. Except for Section 6.07, nothing in this Agreement, expressed or implied, is intended to confer upon any Person, other than the parties hereto or their respective successors, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

9.08. Effect. No provision of this Agreement shall be construed to require the Company, Placer or any of their respective Subsidiaries or any Affiliates or directors of any of them to take any action or omit to take any action which action or omission would violate applicable law (whether statutory or common law), rule or regulation.

9.09. Severability. Except to the extent that application of this Section 9.09 would have a Company Material Adverse Effect or Placer Material Adverse Effect, as the case may be, or would prevent, materially delay or materially impair the ability of the Company or any of its Subsidiaries or Placer to consummate the transactions contemplated by this Agreement, any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

9.10. Enforcement of the Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

9.11. Interpretation. When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of, or Exhibit or Schedule to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”.

9.12. Assignment. This Agreement shall not be assignable by operation of law or otherwise, without the prior written consent of each of the parties.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed in counterparts by their duly authorized officers, all as of the day and year first above written.
