THIS ACQUISITION AGREEMENT, dated as of November 5, 2004 (the "Agreement"), is entered into by and among SEQUOIA NATIONAL BANK, a national banking association with its main office in San Francisco, California ("Sequoia"), FIRST NATIONAL BANK OF NORTHERN CALIFORNIA, a national banking association with its main office in South San Francisco, California ("FNB"), and HEMISPHERE NATIONAL BANK, a national banking association with its main office in Miami, Florida ("HNB").

WHEREAS, Sequoia and FNB are national banking associations, each engaged in the business of banking in the State of California and HNB is a national banking association engaged in the business of banking in the State of Florida;

WHEREAS, Sequoia and FNB desire to consummate a plan of consolidation pursuant to 12 USC 215 (the "Consolidation") whereby an interim national bank will be organized by FNB (the "Interim National Bank") for the purpose of consolidating with Sequoia under the charter of Sequoia and pursuant to which the shareholders of Sequoia will receive the Consolidation Consideration (as defined in Section 1.9 below) and all of the issued and outstanding shares of the Interim National Bank will be converted into shares of common stock of the resulting institution in the consolidation (the "Consolidated Bank"), on the terms and subject to the conditions provided for in this Agreement and as approved by the Office of the Comptroller of the Currency (the "OCC");

WHEREAS, upon organization of the Interim National Bank, the Interim National Bank will become a party to this Agreement by the execution and delivery of an addendum to this Agreement, in form and substance acceptable to FNB, Sequoia, HNB and the directors and shareholders of the Interim National Bank;

WHEREAS, prior to consummation of the Consolidation, Sequoia intends to apply for and obtain all bank regulatory approvals required to relocate its main office from 65 Post Street, San Francisco, California to Los Angeles, California (the "Branch Authorization");

WHEREAS, immediately after consummation of the Consolidation, FNB intends to effect a liquidation of the Consolidated Bank pursuant to Section 332 of the Internal Revenue Code of 1986, as amended, whereby the Consolidated Bank will sell, assign and transfer to FNB, substantially all of the assets, liabilities and obligations associated with the banking business presently being conducted by Sequoia under the name "Sequoia National Bank" (the "Business") at 65 Post Street, San Francisco, California, and at 699 Portola Drive, San Francisco, California (the "Branches"), on the terms and subject to the conditions set forth in this Agreement and in a plan of liquidation to be submitted to and approved by the OCC (the "Liquidation");

WHEREAS, pursuant to said plan of liquidation, the Consolidated Bank will retain the Branch Authorization and certain other assets required under applicable law to maintain its status as a national bank;

WHEREAS, the sole reason for not dissolving the national bank status of the Consolidated Bank in connection with the Liquidation would be to isolate the value of the Branch Authorization for sale to HNB, a purchaser that is not related to Sequoia, FNB or their shareholders (within the meaning of Section 318(a) of the Internal Revenue Code of 1986, as modified by Section 304(c)(3) of such Code);

WHEREAS, simultaneous with consummation of the Liquidation, HNB intends to purchase, and FNB is willing to sell, one hundred percent (100%) of the outstanding capital stock of the Consolidated Bank, all of which will be beneficially owned by FNB upon consummation of the Consolidation, in consideration of the payment of the Stock Purchase Price (as defined in Section 3.2 below), on the terms and subject to the conditions provided for in this Agreement (the "Stock Purchase");

WHEREAS, immediately after consummation of the Stock Purchase, HNB intends to merge the Consolidated Bank with and into HNB (the "Bank Merger"), and HNB shall be the banking association surviving the merger with a branch office located in Los Angeles, California;

WHEREAS, Sequoia, FNB and HNB intend for the Consolidation, the Liquidation, the Stock Purchase and the Bank Merger to occur for all practical purposes simultaneously, and in any event with effect (to the greatest extent practicable) on the same business day, except that, Sequoia and FNB also fully intend to consummate and close the Consolidation and the Liquidation (as provided in Section 5.5 of this Agreement) irrespective of whether the Stock Purchase and the Bank Merger are consummated and closed with HNB on the same business day or at all; and

WHEREAS, consummation of the Consolidation, the Liquidation, the Stock Purchase and the Bank Merger will be submitted to a vote of the shareholders of FNB, Sequoia, HNB and the Interim National Bank, as necessary or appropriate, in order to obtain such approvals as may be required by applicable law;

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements set forth in this Agreement, the parties agree as follows:

PLAN OF CONSOLIDATION

1.1 Plan of Consolidation. FNB, Sequoia and HNB agree that, when organized and chartered by the OCC, the Interim National Bank shall become a party to this Agreement by the execution and delivery of an addendum to this Agreement, in form and substance acceptable to FNB, Sequoia, HNB and the directors and shareholders of the Interim National Bank. At the Effective Time (as hereinafter defined) and upon the terms and subject to the conditions of this Agreement, the corporate existence of each of Sequoia and Interim National Bank shall be merged into and continued as a consolidated national banking association under the national bank charter of Sequoia pursuant to 12 USC 215.

1.2 Effective Time. As soon as practicable after the satisfaction or waiver of the conditions set forth in Article 8, the Interim National Bank and Sequoia will enter into a consolidation agreement, substantially in the form attached hereto as Exhibit A (the "Consolidation Agreement") and the parties hereto will file the Consolidation Agreement with the OCC and make all other filings and recordings required by 12 USC 215 or the OCC. The Consolidation shall become effective at such time as specified by the OCC (the "Effective Time").

1.3 Effects of Consolidation. The Consolidation shall have the effects set forth in 12 USC 215. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of Sequoia and the Interim National Bank shall vest in the Consolidated Bank, and all debts, liabilities and duties of Sequoia and the Interim National Bank shall become the debts, liabilities and duties of the Consolidated Bank.

(a) The Articles of Association of Sequoia, as in effect immediately prior to the Effective Time, shall be the Articles of Association of the Consolidated Bank until thereafter amended as provided therein and under the National Bank Act. Subject to receipt of the Branch Authorization, FNB will cause the Articles of Association of the Consolidated Bank to be amended to reflect the relocation of its main office to Los Angeles as of the Effective Time.

(b) The Bylaws of Sequoia, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Consolidated Bank until thereafter amended as provided therein and under the National Bank Act.

1.5 Directors. The directors of the Interim National Bank at the Effective Time shall be the initial directors of the Consolidated Bank, each to hold office in accordance with the Articles of Association and Bylaws of the Consolidated Bank and until his or her successor is duly elected and qualified.

1.6 Officers. The officers of the Interim National Bank at the Effective Time shall be the initial officers of the Consolidated Bank, each to hold office in accordance with the Articles of Association and Bylaws of the Consolidated Bank and until his or her successor is duly elected or appointed and qualified.

1.7 Conversion of Securities. At the Effective Time, pursuant to the terms of the Consolidation Agreement and without any further action on the part of the Interim National Bank, Sequoia or any shareholder of the Interim National Bank or Sequoia:

(a) Each share of Sequoia Common Stock ("Share") that prior to the Consolidation is held in the treasury of Sequoia or of any of its subsidiaries, or owned by FNB or the Interim National Bank or any of their subsidiaries, shall be canceled and retired and no capital stock of the Consolidated Bank, cash or other consideration shall be paid or delivered in exchange therefor.

(b) Except for any Dissenting Shares (as defined in Section 1.10 hereof), each then outstanding Share shall be converted into the right to receive an amount in cash, without interest, equal to the "Consolidation Purchase Price Per Share" (as defined in Section 1.9(c) below).

(c) Each share of Common Stock of the Interim National Bank ("Interim Bank Stock") outstanding immediately prior to the Effective Time shall be converted into and become such number of validly issued, fully paid and nonassessable shares of Common Stock of the Consolidated Bank (the "Consolidated Bank Stock"), equal to the quotient obtained by dividing (i) the sum of the number of Shares (including Dissenting Shares) and shares of Interim Bank Stock outstanding immediately prior to the Effective Time, by (ii) the number of shares of Interim Bank Stock outstanding immediately prior to the Effective Time, representing ownership of one hundred percent (100%) of the issued and outstanding capital stock of the Consolidated Bank, all of which shall be beneficially owned by FNB.

(d) The capital and surplus of the Consolidated Bank will equal the combined capital and surplus of Sequoia and Interim National Bank immediately prior to the Consolidation.

(e) At the Effective Time, the stock transfer books of Sequoia shall be closed and no transfer of Shares shall thereafter be made.

1.8 Stock Options. All stock options and stock option agreements outstanding at the Effective Time under Sequoia's Stock Option Plan (the "Stock Option Plan"), whether or not vested, shall be terminated prior to the Effective Time and, effective as of the Effective Time, each holder of any such stock option shall become entitled to receive from Sequoia, payable from the "Payment Fund" (as defined in Section 1.11 below) for each share of Sequoia Common Stock subject to such stock option, an amount in cash in cancellation thereof equal to the excess, if any, of the "Consolidation Purchase Price Per Share" (as defined in Section 1.9(c) below) over the per share exercise price of such option. Except as may be necessary to effect the cancellation of all outstanding stock options and stock option agreements, the Stock Option Plan shall be terminated by the Sequoia Board of Directors prior to the Effective Time, and neither the Stock Option Plan nor any option outstanding under the Stock Option Plan shall be included in the Consolidation. Sequoia hereby undertakes and agrees to terminate the Stock Option Plan and to assume all responsibility for the cancellation of options as contemplated by this Section 1.8, and further agrees to indemnify and hold harmless FNB, the Interim National Bank and the Consolidated Bank for and in respect of any claims made by an optionee related to the cancellation of his or her stock option or options and stock option agreement(s).

(a) At the Closing, in consideration of the Consolidation, FNB agrees to deposit in the "Payment Fund" (as defined in Section 1.11 below) and in the "Escrow Account" (as defined in Section 1.12 below), as hereinafter provided, the cash consideration (the "Consolidation Consideration") consisting of (i) $4,874,000, adjusted for the "Adjustments," as described in subparagraph 1.9(b) below, plus (ii) an amount equal to Sequoia's stockholders' equity, as reflected on the Closing Balance Sheet described in Section 8.2(f) of this Agreement (the amounts in (i) and (ii), together, hereinafter called the "Closing Payment Amount"), plus (iii) an amount equal to the Stock Purchase Price, if and when the Stock Purchase Price is paid by HNB pursuant to Section 3.2 below. The Closing Payment Amount, less the sum of $1,500,000 (to be held in

escrow), shall be paid by wire transfer in immediately available funds to the "Paying Agent" for deposit into the "Payment Fund," as such terms are defined in
Section 1.11, to be held and disbursed in accordance with the "Paying Agent Agreement" described in Section 1.11, and the said $1,500,000 shall be paid by wire transfer in immediately available funds to the "Escrow Agent" for deposit into the "Escrow Account," as such terms are defined in Section 1.12, to be held and disbursed in accordance with the "Escrow Agent Agreement" described in
Section 1.12.

(b) For purposes of this Section 1.9, the term "Adjustments" means
(i) the adjustments necessary to reflect the market value of all held-to-maturity securities and all available-for-sale securities in the category of "securities" and all other equity securities and financial assets, and (ii) the adjustments necessary to reflect an allowance for loan and lease losses of not less than Seven Hundred Thousand Dollars ($700,000), provided, however, that any additions to the allowance for loan and lease losses, made at the request of FNB pursuant to Section 8.2(c) below, to the extent such additions cause the total allowance for loan and lease losses to exceed Seven Hundred Thousand Dollars ($700,000), shall not be a reduction in the Closing Payment Amount.

(c) The term "Consolidation Purchase Price Per Share" as used in this Agreement shall have the same meaning as specified in the "Paying Agent Agreement" and the amounts payable to the former shareholders of Sequoia under
Section 1.7(b) above and to the former Sequoia optionees under Section 1.8 above shall be calculated and disbursed by the "Paying Agent" in accordance with the provisions of the "Paying Agent Agreement" (as such terms are defined in Section 1.11 below).

(a) Notwithstanding anything in this Agreement to the contrary, Shares that are outstanding immediately prior to the Effective Time and that are held by any Sequoia shareholder who shall have voted such Shares against the Consolidation at the meeting of shareholders required by 12 USC 215, or who shall have delivered at or prior to such meeting to the presiding officer a written notice of dissent from the plan of consolidation in the manner provided in subparagraph (b) of 12 USC 215 ("Dissenting Shares"), shall not be converted into or be exchangeable for the right to receive any portion of the Consolidation Consideration, but the holders of Dissenting Shares shall be entitled to payment of the value of such Dissenting Shares as of the Effective Time upon written request made to the Consolidated Bank at any time before thirty (30) days after the Effective Time, accompanied by the surrender of his or her stock certificates, in accordance with the provisions of subparagraph (b) of 12 USC 215, provided, however, that if any such shareholder shall waive his or her right to demand payment under 12 USC 215, or a court of competent jurisdiction shall determine that such shareholder is not entitled to relief provided by 12 USC 215, then the right of such holder of Dissenting Shares to be paid the value of his or her Shares shall cease and such Dissenting Shares shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Consolidation Purchase Price Per Share, without any interest thereon, and the "Paying Agent" shall disburse to such shareholder the Consolidation Purchase Price Per Share applicable to such Shares, utilizing funds in the "Dissenting Shares Account," in accordance with the provisions of the "Paying Agent Agreement" (as the terms "Paying Agent," "Dissenting Shares Account" and "Paying Agent Agreement" are defined in Section 1.11).

(b) With respect to holders of Dissenting Shares who perfect their rights to receive the value of their Shares pursuant to 12 USC 215:

(i) if the value of such Dissenting Shares is determined pursuant to 12 USC 215 to be less than the Consolidation Purchase Price Per Share, then each holder of such Dissenting Shares shall be entitled to receive from the "Paying Agent," out of the funds on deposit in the "Dissenting Shares Account," the value of such Dissenting Shares as so determined; or

(ii) if the value of such Dissenting Shares is determined pursuant to 12 USC 215 to be greater than the Consolidation Purchase Price Per Share, then the "Paying Agent" shall request authority to transfer from the "Payment Fund" to the "Dissenting Shares Account" an amount equal to the excess of the value of the Dissenting Shares over the Consolidation Purchase Price Per Share and each holder of such Dissenting Shares shall then be entitled to receive from the "Paying Agent," out of funds on deposit in the "Dissenting Shares Account," the value of such Dissenting Shares as so determined.

The terms "Paying Agent," "Payment Fund," and "Dissenting Shares Account" are defined in Section 1.11, and the rights, duties and obligations of the "Paying Agent" in respect of the Dissenting Shares and the disposition of any funds still remaining in the "Dissenting Shares Account" after making the payments to holders of Dissenting Shares as described in this Section 1.10 shall be governed by the provisions of the "Paying Agent Agreement" (defined in
Section 1.11).

(a) FNB and Sequoia agree that Wells Fargo Bank, National Association, or another bank or trust company hereafter designated by Sequoia and approved by FNB shall act as the paying agent for the Consolidation (the "Paying Agent"). Contemporaneous with execution and delivery of the Consolidation Agreement, FNB, the Interim National Bank, Sequoia and the Paying Agent shall enter into an agreement, substantially in the form attached hereto as Exhibit B (the "Paying Agent Agreement"), providing for the rights, duties and obligations of the Paying Agent in relation to this Agreement. At the Effective Time, in accordance with Section 1.9(a), FNB shall cause the Closing Payment Amount, less the sum of $1,500,000, to be delivered to the Paying Agent for deposit into an account (the "Payment Fund") to be established, administered and disbursed by the Paying Agent (together with any other funds delivered to the Paying Agent for deposit into the Payment Fund pursuant to Section 1.12 below and the "Escrow Agent Agreement" defined therein) in accordance with the provisions of the Paying Agent Agreement. The Paying Agent Agreement shall require the Paying Agent to establish a sub-account of the Payment Fund, as necessary (the "Dissenting Shares Account") to hold, administer and disburse the funds payable to dissenting shareholders (if any) as described in Section 1.10 above. Pursuant to the provisions of the Paying Agent Agreement, the Paying Agent shall make payments from the Payment Fund to the Sequoia optionees and shareholders, as required by Sections 1.8 and 1.9 (against surrender to the Paying Agent of Sequoia stock option agreements or stock certificates for cancellation) and shall make payments from the Dissenting Shares Account to the holders (if any) of Dissenting Shares, as required by Section 1.10. The Payment Fund may be invested by the Paying Agent, as will be authorized by the Paying Agent Agreement, and any net earnings with respect thereto shall be applied or

paid as provided in the Paying Agent Agreement; provided, however, that the fees and expenses of the Paying Agent shall be paid out of the funds held in the Payment Fund, including any net earnings with respect to such funds.

(b) In no event shall the holders of any surrendered certificates for Shares or stock option agreements be entitled to receive interest on any of the funds entitled to be received by such holders in the Consolidation. If payment is to be made to a person other than the person in whose name any certificates for Shares surrendered are registered, it shall be a condition of the payment that the certificates so surrendered shall be properly endorsed and the signatures thereon properly guaranteed and otherwise in proper form for transfer and that the person requesting such payment shall pay to the Paying Agent any transfer or other taxes required by reason of the delivery of such check to a person other than the registered holder of the certificate surrendered, or shall establish to the satisfaction of the Paying Agent that such tax has been paid or is not applicable. Notwithstanding the foregoing, neither the Paying Agent nor any party hereto shall be liable to a holder of Shares for any amount paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(c) The cash paid upon the surrender of certificates representing Shares or in respect of the termination of any stock option in accordance with the terms hereof shall be deemed to have been paid, issued and distributed in full satisfaction of all rights pertaining to such Shares or stock options.

(d) Any cash delivered or made available to the Paying Agent pursuant to this Section 1.11 and not exchanged for certificates representing Shares within one hundred twenty (120) days after the Effective Time pursuant hereto shall be forwarded by the Paying Agent to FNB (or its designated agent) which shall thereafter act as the successor paying agent, as provided in the Paying Agent Agreement.

1.12 Post-Closing Payments. FNB and Sequoia agree that Wells Fargo Bank, National Association, or another bank or trust company hereafter designated by FNB and approved by Sequoia shall act as the escrow agent (the "Escrow Agent") for the sum of $1,500,000 held back from the Closing Payment Amount pursuant to
Section 1.9(a) above. Contemporaneous with execution and delivery of the Consolidation Agreement, FNB, the Interim National Bank, Sequoia and the Escrow Agent shall enter into an agreement, substantially in the form attached hereto as Exhibit C (the "Escrow Agent Agreement"), providing for the rights, duties and obligations of the Escrow Agent in relation to this Agreement. At the Effective Time, in accordance with Section 1.9(a), FNB shall cause the $1,500,000 hold-back to be delivered to the Escrow Agent for deposit into an account (the "Escrow Account") to be established, administered and disbursed by the Escrow Agent in accordance with the provisions of the Escrow Agent Agreement. Also at the Effective Time, in accordance with Section 3.2 of this Agreement, HNB shall cause the Stock Purchase Price to be delivered to the Escrow Agent for deposit into the Escrow Account. Pursuant to the Escrow Agent Agreement, the Escrow Agent shall forward an amount equal to the Stock Purchase Price (within one (1) business day after receipt of good funds from HNB) to the Paying Agent for deposit into the Payment Fund and disposition in accordance with the Paying Agent Agreement. The Escrow Agent may utilize the funds held in the Escrow Account (as authorized by the terms of the Escrow Agent Agreement) to indemnify and reimburse FNB for (i) the federal and state franchise taxes due in respect of the Stock Purchase, (ii) the present value of lost tax benefits associated with Sequoia's net operating losses versus the tax amortization of

(ii) Sequoia shall not sell, transfer, mortgage, encumber or otherwise dispose of any of the Assets except for the disposition of Assets in the ordinary course of business;

(v) Sequoia shall operate the Branches and the Business in accordance with its normal practices and will use commercial best efforts to preserve for the benefit of FNB after the Closing its business, goodwill and relationships with customers and suppliers;

(vi) Sequoia shall furnish to FNB such reports and compilations pertaining thereto as FNB shall reasonably request from time to time; and Sequoia shall furnish to FNB all such other information pertaining to the Assets and the Assumed Liabilities and the Business as FNB may reasonably request; and Sequoia shall use its best efforts to cause its officers, employees, independent accountants and attorneys to cooperate with FNB in its reasonable requests for information.

(vii) Sequoia shall permit FNB (or an officer of FNB designated by the Board of Directors of FNB) to attend and observe all loan committee meetings or other meetings of Sequoia for the purpose of approving loans or similar extensions or renewals of credit. Sequoia shall not, without first having obtained the written consent or waiver of FNB (or an officer of FNB designated by the Board of Directors of FNB) cause, allow or suffer its officers or agents to commit to any new loan or renewal of an existing loan which does not, in the opinion of FNB (or in the opinion of an officer of FNB designated by the Board of Directors of FNB), comply in all material respects with the written credit policies of Sequoia in effect and as disclosed to FNB prior to the date of this Agreement, provided, however, that such consent or waiver shall be deemed to have been given if no response is provided to Sequoia following a written request therefore within five (5) business days of receipt of such request;

(b) FNB's Access to Branch Premises. Prior to the Closing, Sequoia shall provide FNB and its attorneys, independent accountants and agents, reasonable access to the Branches during normal business hours and upon reasonable request, reasonable opportunity to review and inspect the furniture, fixtures and equipment, and the books, records, files, documentation and accounts of the Business, and Sequoia shall allow FNB to make copies of such materials (excluding regulatory examinations and correspondence to the extent not prohibited by applicable law or regulation). FNB will indemnify, defend, and hold Sequoia harmless for, from and against any and all claims, damages, costs, liabilities and losses (including mechanics' liens) arising out of any entry by FNB or its agents, designees or representatives on the premises of the Branches for any purpose. Without limiting the scope of the foregoing, FNB also will restore the furniture, fixtures and equipment, books, records, files, and documentation of the Branches at its sole cost and expense, as necessary, if the transactions contemplated by this Agreement do not close.

In connection with the conversion of the data processing, Sequoia and FNB shall each cooperate with the other and shall bear equally the duties and responsibilities relating to the conversion.

meeting of its shareholders to consider and vote upon the approval and adoption of this Agreement, the Consolidation and the Liquidation and for such other purposes as may be necessary or desirable. The Sequoia Board of Directors has determined that this Agreement and the transactions contemplated herein are advisable and in the best interests of the Sequoia shareholders and, subject to the fiduciary obligations of a director as advised by legal counsel, each member of the Sequoia Board of Directors has executed and delivered to Sequoia, dated as of the date of this Agreement, a director-shareholder agreement addressed to FNB substantially in the form attached hereto as Exhibit I ("Director-Shareholder Agreement"), pursuant to which each member of the Sequoia Board of Directors in the capacity of a shareholder has committed to vote his or her shares of Sequoia Common Stock in favor of this Agreement and the transactions described herein and to recommend to all other shareholders that they also vote in favor of this Agreement and the transactions described herein.

To the extent consistent with FNB's existing structure for comparable positions and comparable officer titles and its current policies regarding officer titles, any employees who may be offered employment with FNB shall be offered positions with responsibilities and officer titles that are substantially comparable to those they held with Sequoia before the Closing Date. All employees who accept employment with FNB as of the Closing Date will be eligible to participate in the employee benefit plans and other fringe benefits of FNB on the same basis as such plans and benefits are offered to the other employees of FNB with comparable positions with FNB.

Sequoia and HNB shall have the right to review and comment upon all applications to, and filings with, governmental and regulatory agencies and entities made by FNB for the above purpose, prior to their filing; provided that, neither Sequoia nor HNB shall have responsibility for any such application or filing. Without limiting the generality of the foregoing, FNB shall use commercial best efforts to file all required regulatory applications within thirty (30) calendar days after the date of this Agreement; and

(c) use its commercial best efforts to apply for and obtain all regulatory and other requirements, including without limitation from the OCC, and to take all corporate actions necessary to form and organize the Interim National Bank, to vote all shares of the Interim National Bank in favor of approval and adoption of this Agreement and the Consolidation and the Liquidation and to cause the Interim National Bank to take all other actions that may be necessary or appropriate to cause the Interim National Bank to effectuate the Consolidation and the Liquidation on the terms and subject to the conditions provided for in this Agreement and in the Consolidation Agreement and in the Plan of Liquidation.

No party shall act unilaterally in this regard without the prior approval of the other parties, which shall not be unreasonably withheld or delayed; provided, however, that in the event that a party reasonably concludes that a public announcement or release is required by applicable law and the parties cannot reach agreement upon a mutually acceptable release, the party releasing the information, announcement or public statement shall not be deemed to be in breach of this Agreement.

10.2 Assignment. No party shall assign this Agreement or any of its rights, duties or obligations hereunder without the prior written consent of the other parties.

10.3 Notices. Notices and legal process to be delivered to or served upon a party hereto shall be deemed to have been duly delivered or served when delivered in written form by hand or by facsimile transmission, on the day after being sent from within the continental United States by overnight delivery or courier service, or three (3) calendar days after posting by registered mail or certified mail with return receipt requested, to the parties hereto at the following addresses:

10.4 Expenses. Except as otherwise expressly provided herein, each party shall bear its own out-of-pocket expenses incurred in connection with the transactions contemplated by this Agreement.

10.5 Entire Agreement. This Agreement embodies the entire agreement and understanding among the parties hereto and supersedes all prior agreements and understandings relating to the subject matter of this Agreement.

10.6 Governing Law, Severability. This Agreement shall be governed by and construed in accordance with the substantive laws and not the conflict laws of the State of California and the provisions of the laws of the United States of America applicable to national banking associations. If any one or more of the provisions of this Agreement shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision were not contained herein.

10.7 Waiver and Amendment. No delay or omission to exercise any right, power or remedy accruing to any party upon any breach or default under this Agreement shall impair any such right, power or remedy of such party, nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach of default theretofore or thereafter occurring. Any waiver, permit, consent or approval or any kind or character of any breach or default under this Agreement, or any waiver of any provision or condition of this Agreement, or any other change or amendment, must be in writing and shall be effective only to the extent specifically set forth in such writing. All rights and remedies, either

under this Agreement or by law or otherwise afforded to a party, shall be cumulative and not alternative.

10.8 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original instrument, but all of which together shall constitute one and the same instrument.

10.9 Confidentiality. FNB, Sequoia and HNB, and their respective representatives, agents and designees, shall keep confidential and shall not disclose to any person or entity, without the prior written consent of the other parties, the Consolidation Consideration, the Stock Purchase Price, the existence of this Agreement or any of the terms or conditions hereof or the status of the transactions contemplated hereby except to the extent required by law to comply with applicable securities laws and in connection with the solicitation of required shareholder approvals. These restrictions, however, shall not apply to any such information (i) that becomes public knowledge through no fault, act or omission of any party or their respective representatives, agents or designees, (ii) that any party lawfully acquires from an entity not under an obligation of confidentiality to any other party, (iii) that is independently developed by a party, or (iv) where any party is legally compelled to disclose such information; provided, however, that the other parties are provided with advance written notice of the intention to disclose in order to allow such other parties to contest the proposed disclosure before any court or agency with jurisdiction unless such notice impedes a duty or obligation under applicable laws, regulations or legal requirements to timely report such information, in which event FNB, Sequoia, or HNB (as the case may be) shall concurrently advise the other parties of its disclosure.

10.10 Third-Party Rights. Nothing contained in this Agreement, whether express or implied, is intended to (i) confer any rights or remedies upon any persons other than the parties hereto and their respective successors and assigns, (ii) relieve or discharge the obligations or liabilities of any third person to any party to this Agreement, or (iii) give any third person any right of subrogation or action over any party to this Agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized officers or representatives as of the date first above written.
