At the Effective Time, for the benefit of the holders of Certificates and/or Book-Entry Shares, TriCo shall deliver to the Exchange Agent certificates, or at TriCo’s option, evidence of shares in book entry form, representing the number of shares of TriCo Common Stock issuable to the holders of FNBB Common Stock as the Merger Consideration, to be given to the holders of FNBB Common Stock in exchange for their Certificates and Book-Entry Shares as provided for in this Article III. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the shares of TriCo 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.

(i) Each holder of an outstanding Certificate or Certificates or Book-Entry Shares who has surrendered such Certificate or Certificates to the Exchange Agent will, upon acceptance thereof by the Exchange Agent, be entitled to evidence of issuance in book entry form, or upon written request of such holder, a certificate or certificates representing, the number of whole shares of TriCo Common Stock into which the aggregate number of shares of FNBB Common Stock previously represented by such Certificate or Certificates or Book-Entry Shares surrendered shall have been converted pursuant to this Agreement and any other distribution theretofore paid with respect to TriCo Common Stock issuable in the Merger, in each case, without interest. The Exchange Agent shall accept such Certificates or Book-Entry Shares upon compliance with such reasonable terms and conditions as the Exchange Agent may impose consistent with the notice and form of letter of transmittal to effect an orderly exchange thereof in accordance with normal exchange practices.

(ii) Each outstanding Certificate or Book-Entry Share which prior to the Effective Time represented FNBB Common Stock and which is not surrendered to the Exchange Agent in accordance with the procedures provided for herein shall, except as otherwise herein provided, until duly surrendered to the Exchange Agent, be deemed to evidence ownership of the number of shares of TriCo Common Stock into which such FNBB Common Stock shall have been converted. After the Effective Time, there shall be no further transfer on the records of FNBB of Certificates or Book-Entry Shares representing shares of FNBB Common Stock and, if such Certificates or Book-Entry Shares are presented to FNBB for

-12-

transfer, they shall be cancelled against delivery of certificates for TriCo Common Stock as hereinabove provided. No dividends which have been declared will be remitted to any Person entitled to receive shares of TriCo Common Stock under Section 3.01 until such Person surrenders the Certificate or Certificates or Book-Entry Shares representing FNBB Common Stock, at which time such dividends shall be remitted to such Person, without interest.

(d) Lost or Destroyed Certificates; Issuances of TriCo Common Stock in New Names. The Exchange Agent and TriCo, as the case may be, shall not be obligated to deliver a certificate or certificates representing shares of TriCo Common Stock to which a holder of FNBB Common Stock would otherwise be entitled as a result of the Merger until such holder surrenders the Certificate or Certificates representing the shares of FNBB Common Stock for exchange as provided in this Section 3.02, or, in default thereof, an appropriate affidavit of loss and indemnity agreement and/or a bond in an amount as may be reasonably required in each case by TriCo. If any certificates evidencing shares of TriCo Common Stock are to be issued in a name other than that in which the Certificate evidencing FNBB Common Stock surrendered in exchange therefore is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be properly endorsed or accompanied by an executed form of assignment separate from the Certificate and otherwise in proper form for transfer and that the Person requesting such exchange pay to the Exchange Agent any transfer or other Tax required by reason of the issuance of a certificate for shares of TriCo Common Stock in any name other than that of the registered holder of the Certificate surrendered or otherwise establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) Unclaimed Merger Consideration. Any portion of the shares of TriCo Common Stock delivered to the Exchange Agent by TriCo pursuant to Section 3.02(b) that remains unclaimed by the shareholders of FNBB for twelve (12) months after the Effective Time (as well as any proceeds from any investment thereof) shall be delivered by the Exchange Agent to TriCo. Any shareholders of FNBB who have not theretofore complied with Section 3.02(c) shall thereafter look only to TriCo for the consideration deliverable in respect of each share of FNBB Common Stock such shareholder holds as determined pursuant to this Agreement without any interest thereon. If outstanding Certificates or Book-Entry Shares are not surrendered or the payment for them is not claimed prior to the date on which such shares of TriCo Common Stock would otherwise escheat to any governmental unit or agency, the unclaimed items shall, to the extent permitted by abandoned property and any other applicable law, become the property of TriCo (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any party to this Agreement shall be liable to any holder of stock represented by any Certificate or Book-Entry Share for any consideration paid to a public official pursuant to applicable abandoned property, escheat or similar laws. TriCo and the Exchange Agent shall be entitled to rely upon the stock transfer books of FNBB to establish the identity of those Persons entitled to receive the consideration specified in this Agreement, which books shall be conclusive (absent manifest error) with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Certificate or Book-Entry Share, TriCo and the Exchange Agent shall be entitled to deposit any consideration represented thereby in escrow with an independent third party and thereafter be relieved with respect to any claims thereto.

-13-

3.03 Rights as Shareholders. At the Effective Time, holders of FNBB Common Stock shall cease to be, and shall have no rights as, shareholders of FNBB other than to receive the consideration provided for under this Article III.

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

3.05 Anti-Dilution Provisions. If, between the date hereof and the Effective Time, the shares of TriCo Common Stock shall be changed into a different number or class of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares or readjustment, or similar transaction, or a stock dividend thereon shall be declared with a record date within said period, the Merger Consideration and Exchange Ratio shall be adjusted accordingly; provided that a bona fide offering or sale of TriCo Common Stock for fair value received shall not be deemed a reclassification, recapitalization, split-up, combination, exchange of shares or readjustment of the TriCo Common Stock.

3.06 Withholding Rights. TriCo (through the Exchange Agent, if applicable) shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any holder of shares of FNBB Common Stock such amounts as TriCo is required under the Code or any state, local or foreign Tax law or regulation thereunder to deduct and withhold with respect to the making of such payment. Any amounts so withheld shall be timely remitted to the applicable Governmental Entity and shall be treated for all purposes of this Agreement as having been paid to the holder of FNBB Common Stock in respect of which such deduction and withholding was made by TriCo.

3.07 FNBB Options.

(a) At the Effective Time, each FNBB Option, whether vested or unvested, shall be cancelled and shall only entitle the holder of such FNBB Option to receive, as soon as administratively practicable after the Effective Time, an amount in cash equal to the product of (i) the total number of shares of FNBB Common Stock subject to such FNBB Option multiplied by (ii) the amount, if any, that the product of the TriCo Average Closing Price multiplied by the Exchange Ratio exceeds the exercise price per share of such FNBB Option, less any applicable Taxes required to be withheld with respect to such payment (such amount, the “Option Consideration”); provided that to the extent reasonably practicable and permitted by Code Section 409A, TriCo may elect to fund the Option Consideration to be paid with respect to FNBB Options by funding the necessary amounts to the payroll processor of FNBB or TriCo or any of their respective Affiliates (the “Payroll Processor”) for payment by the Payroll Processor of the Option Consideration to the applicable holders of such FNBB Options. For the avoidance of doubt, any FNBB Option which has an exercise price per share of FNBB Common Stock that is greater than or equal to the product of the TriCo Average Closing Price multiplied by the Exchange Ratio shall be cancelled at the Effective Time for no consideration or payment.

-14-

(b) At least fifteen (15) days prior to the Closing Date and prior to any such payment, FNBB shall obtain a written acknowledgement and waiver (in form and substance reasonably satisfactory to FNBB and TriCo) from each holder of an FNBB Option (i) confirming the number of FNBB Options held (and shares of FNBB Common Stock subject to such FNBB Options), (ii) confirming that the treatment of such FNBB Options pursuant to this Agreement and the amounts to be paid pursuant to this Agreement have been correctly calculated and (iii) acknowledging that in consideration for the cancellation of such FNBB Option, the holder agrees to accept the Option Consideration. FNBB shall provide a copy of each such acknowledgement and waiver to TriCo at least five (5) Business Days prior to the Closing Date.

(c) Prior to the Effective Time, the FNBB Board shall adopt any necessary resolutions and take any actions necessary to (i) effectuate the provisions of Section 3.07(a) and 3.07(b) and (ii) cause all FNBB Options to vest in full as of the Effective Time to the extent permitted under the applicable FNBB Option Plan and be terminated as of the Effective Time.

5.02 Standard. Solely for the purposes of determining whether the conditions set forth in Sections 7.02(a) or 7.03(a), as the case may be, have been satisfied (and without otherwise qualifying any representation or warranty made on the date hereof), no representation or warranty of FNBB on the one hand or TriCo on the other hand contained in Sections 5.03 or 5.04, respectively (other than (a) the representations of FNBB contained in Section 5.03(b), which shall be true in all respects, except to a de minimis extent (relative to Section 5.03(b) taken as a whole), (b) the representations of FNBB contained in Sections 5.03(d), 5.03(e), 5.03(g)(iii) and 5.03(i), and the representations of TriCo contained in Section 5.04(g)(ii), which shall be true and correct in all respects, and (c) the representations of FNBB contained in Section 5.03(m)(v), which shall be true in all material respects) shall be deemed untrue or incorrect for purposes of Sections 7.02(a) or 7.03(a), and no party hereto shall be deemed to have breached a representation or warranty for purposes of such Sections, as a consequence of the existence of any fact, event or circumstance unless such fact, circumstance or event, individually or taken together with all other facts, events or circumstances inconsistent with any representation or warranty contained in Sections 5.03 or 5.04, has had or is reasonably likely to have a Material Adverse Effect on the party making such representation or warranty.

-47-

(j) Regulatory Matters.

(i) Since December 31, 2013, TriCo and each of its Subsidiaries has duly filed with the appropriate bank regulatory authorities in substantially correct form the monthly, quarterly and annual reports required to be filed under applicable laws and regulations, and such reports were in all material respects complete, accurate and in compliance with the requirements of applicable laws and regulations. In connection with the most recent examination of TriCo and each of its Subsidiaries by the appropriate regulatory authorities, neither TriCo nor any of its Subsidiaries was required to correct or change any action, procedure or proceeding which TriCo believes in good faith has not now been corrected or changed, other than corrections or changes which, if not made, either individually or in the aggregate, would not have a Material Adverse Effect on TriCo.

(ii) Neither TriCo nor any of its Subsidiaries nor any of their respective properties is a party to or is subject to any order, decree, directive, agreement, memorandum of understanding or similar arrangement with, or a commitment letter or similar submission to, or extraordinary supervisory letter from, nor has TriCo or any of its Subsidiaries adopted any policies, procedures or board resolutions at the request or suggestion of, any Governmental Entity. TriCo and its Subsidiaries have paid all assessments made or imposed by any Governmental Entity.

(iii) Neither TriCo nor any its Subsidiaries has been advised by, and does not have any Knowledge of facts which would reasonably be expected to give rise to an advisory notice by, any Governmental Entity that such Governmental Entity is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, directive, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission or any request for the adoption of any policy, procedure or board resolution.

(iv) (A) No Governmental Entity has initiated since December 31, 2013 or has pending any proceeding, enforcement action or, to TriCo’s Knowledge, investigation or inquiry into the business, operations, policies, practices or disclosures of TriCo or any of its Subsidiaries (other than normal examinations conducted by a Governmental Entity in the ordinary course of the business of TriCo or the applicable Subsidiary), or, to TriCo’s Knowledge, threatened any of the foregoing, and (B) there is no unresolved violation, criticism, comment or exception by any Governmental Entity with respect to any report or statement relating to any examinations or inspections of TriCo or its Subsidiaries, except in each case in subparagraphs (A) and (B), that did not have a Material Adverse Effect.

(v) TriCo and Tri Counties are “well-capitalized” (as that term is defined at 12 CFR §225.2(r) or the relevant regulation of its primary federal bank regulator). The most recent regulatory rating given to Tri Counties as to compliance with the Community Reinvestment Act is no less than “satisfactory.” Neither TriCo nor Tri Counties has received any notification from a Governmental Entity that their status as “well-capitalized” or “satisfactory”

-48-

for Community Reinvestment Act purposes will change within one year, nor does TriCo have Knowledge of any conditions or circumstances that would result in a Community Reinvestment Act rating of less than “satisfactory” or material criticism from regulators with respect to discriminatory lending practices.

(i) is, and at all times since December 31, 2013 has been in material compliance with all applicable federal, state, local and foreign statutes, laws, codes, regulations, ordinances, rules, judgments, injunctions, orders, decrees or policies and/or guidelines of any Governmental Entity applicable thereto or to their employees conducting such businesses, including, without limitation, Section 23A and 23B of the Federal Reserve Act and FRB and FDIC regulations pursuant thereto, the Equal Credit Opportunity Act, the Fair Housing Act, the Community Reinvestment Act, the Home Mortgage Disclosure Act, the Bank Secrecy Act, the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act, the USA PATRIOT Act, the Electronic Fund Transfer Act and Regulation E of the FRB, all other applicable fair lending laws and other laws relating to discriminatory business practices and Environmental Laws and all posted and internal policies of TriCo and its Subsidiaries related to customer data, privacy and security;

(ii) has, and at all times since December 31, 2013 has had, all permits, licenses, franchises, authorizations, orders and approvals of, and has made all filings, applications and registrations with, all Governmental Entities (and has paid all fees and assessments due and payable in connection therewith) that are required in order to permit them to own or lease their properties and to conduct their businesses as presently conducted; all such permits, licenses, certificates of authority, orders and approvals are in full force and effect and, to TriCo’s Knowledge, no suspension or cancellation of any of them is threatened; and

(iii) has received no notification or communication from any Governmental Entity (A) asserting that TriCo or any of its Subsidiaries is not in compliance with any of the statutes, regulations or ordinances which such Governmental Entity enforces or (B) threatening to revoke any license, franchise, permit or governmental authorization (nor, to TriCo’s Knowledge, do any grounds for any of the foregoing exist).

(l) Employee Benefit Plans.

(i) All material benefit and compensation plans, contracts, policies or arrangements maintained, contributed to, obligated to be contributed to, or sponsored by TriCo and Tri Counties for the benefit of current or former employees of TriCo and its Subsidiaries and current or former directors or independent contractors of TriCo and its Subsidiaries including, but not limited to, “employee benefit plans” within the meaning of Section 3(3) of ERISA, any pension, retirement, profit sharing, medical, life, accidental death and dismemberment, disability, dental, vision, compensation, severance, termination pay, salary continuation, unemployment, workers’ compensation, vacation, sick pay, paid-time off, retention, employment, consulting, change in control, fringe benefit, deferred compensation, stock option, stock purchase, stock appreciation rights or other stock-based incentive, cafeteria or flexible benefit, adoption or educational assistance, and bonus or other cash-based incentive, or other similar plans,

agreements, programs, policies or other arrangements (whether written or oral and whether or not qualified or funded) or any such plan for which TriCo and its Subsidiaries may have any liability including, without limitation, as a result of being deemed a single employer with any entity under Section 4001(b)(1) of ERISA or Section 414 of the Code (collectively, the “TriCo Benefit Plans”), have been provided or made available to FNBB.

(ii) Each TriCo Benefit Plan has been established and administered to date in all material respects in accordance with the applicable provisions of ERISA, the Code and applicable law and with the terms and provisions of all documents, contracts or agreements pursuant to which such TriCo Benefit Plan is maintained.

(iii) Other than as disclosed and identified as such in Section 5.04(l)(iii) of TriCo’s Disclosure Schedule, neither TriCo nor any entity considered to be a single employer with TriCo under Section 4001(b)(1) of ERISA or Section 414 of the Code maintains or contributes to any pension plan subject to Title IV of ERISA, to any multiemployer plan (as defined in 4001(a)(3) of ERISA), or to any TriCo Benefit Plan providing for retiree health and life benefits, other than coverage as may be required under Section 4980B of the Code or Part 6 of Title I of ERISA or under the continuation of coverage provisions of the laws of any state or locality.

(m) Tax Matters. (i) All Tax Returns that are required to be filed on or before the Closing Date (taking into account any extensions of time within which to file that have not expired) by or with respect to TriCo or any of its Subsidiaries have been or will be timely filed on or before the Closing Date, (ii) all such Tax Returns are or will be true, correct and complete in all material respects, (iii) all Taxes due and payable by or with respect to TriCo or any of its Subsidiaries (whether or not shown as due on any Tax Return) have been timely paid in full, (iv) the unpaid Taxes of TriCo and its Subsidiaries did not, as of the date of the most recent financial statements, exceed the reserve for Tax liability set forth on the face of such financial statements and do not exceed that reserve as adjusted for the passage of time through the Closing Date in accordance with the past custom and practice of TriCo and its Subsidiaries in filing its Tax Returns, (v) all deficiencies asserted or assessments made as a result of examinations conducted by any taxing authority have been paid in full, (vi) no issues that have been raised by the relevant taxing authority in connection with the examination of any of the Tax Returns referred to in clause (v) are currently pending, and (vii) no claim has been made in writing in the past five (5) years by a taxing authority in a jurisdiction where TriCo or any of its Subsidiaries does not already file Tax Returns that TriCo or a Subsidiary is or may be subject to taxation by that jurisdiction. Neither Trico nor any of its Subsidiaries has taken any action or failed to take any action, or is aware of any fact or circumstance, in each case, that could reasonably be expected to prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code. TriCo has made available to FNBB (A) true and correct copies of the U.S. federal and state income tax returns filed by or on behalf of TriCo and its Subsidiaries for the most recent three (3) years and (B) any audit reports by the respective taxing authorities making adjustments to those returns.

(n) Required Vote; Antitakeover Provisions. The affirmative vote of the holders of a majority of the outstanding shares of TriCo Common Stock entitled to vote is necessary to approve this Agreement and the Transaction on behalf of TriCo.

-50-

(o) Ownership of FNBB Common Stock. None of TriCo or any of its Subsidiaries, or to TriCo’s Knowledge, any of its other affiliates or associates (as such terms are defined under the Exchange Act), owns beneficially or of record, directly or indirectly, or is a party to any agreement, arrangement or understanding for the purpose of acquiring, holding, voting or disposing of, shares of FNBB Common Stock (other than shares held in a fiduciary capacity that are beneficially owned by third parties, shares held in an index or mutual fund, or as a result of debts previously contracted).

(p) Required Vote; Antitakeover Provisions. No “control share acquisition,” “business combination moratorium,” “fair price” or other form of antitakeover statute or regulation under the CGCL or any applicable provisions of the takeover laws of any other state (and any comparable provisions of the TriCo Articles and TriCo Bylaws), apply or will apply to this Agreement, the Bank Merger Agreement or the Transaction.

(q) Disclosure. The representations and warranties contained in this Section 5.04, when considered as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements and information contained in this Section 5.04 not misleading.

(r) No Additional Representations. Except for the representations and warranties made by TriCo in this Section 5.04 and as Previously Disclosed, neither TriCo nor any other Person makes any express or implied representation or warranty with respect to TriCo, its Subsidiaries, or their respective businesses, operations, assets, liabilities, conditions (financial or otherwise) or prospects, and TriCo hereby expressly disclaims any such other representations or warranties.

-51-

consider and vote upon the approval of this Agreement, including the Merger, and any other matters required to be approved by FNBB’s shareholders for consummation of the Transaction (including any adjournment or postponement, the “FNBB Meeting”). Except with the prior approval of TriCo, no other matters shall be submitted for the approval of the FNBB shareholders at the FNBB Meeting. Subject to Section 6.02(b), the FNBB Board shall at all times prior to and during such FNBB Meeting recommend such approval and shall take all reasonable lawful action to solicit such approval by its shareholders and shall not (x) withdraw, modify or qualify in any manner adverse to TriCo such recommendation or (y) take any other action or make any other public statement in connection with the FNBB Meeting inconsistent with such recommendation (collectively, a “Change in Recommendation”), except as and to the extent permitted by Section 6.02(b). Notwithstanding any Change in Recommendation, this Agreement shall be submitted to the shareholders of FNBB at the FNBB Meeting for the purpose of approving the Agreement and any other matters required to be approved by FNBB’s shareholders for consummation of the Transaction. In addition to the foregoing, FNBB shall not submit to the vote of its shareholders any Acquisition Proposal other than the Merger. FNBB hereby acknowledges its obligation to submit this Agreement to its shareholders at the FNBB Meeting as provided in this Section 6.02(a).

(b) Notwithstanding the foregoing, FNBB and the FNBB Board shall be permitted to effect a Change in Recommendation if and only to the extent that:

(i) FNBB shall have complied in all material respects with Section 6.07;

(ii) the FNBB Board, after consulting with its outside counsel and financial advisor, shall have determined in good faith that failure to do so would result in a breach of its fiduciary duties under applicable law; and

(iii) if the FNBB Board intends to effect a Change in Recommendation following receipt of an Acquisition Proposal, (A) the FNBB Board shall have concluded in good faith, after giving effect to all of the adjustments which may be offered by TriCo pursuant to clause (C) below, that such Acquisition Proposal constitutes a Superior Proposal, (B) FNBB shall notify TriCo, at least five (5) Business Days in advance, of its intention to effect a Change in Recommendation in response to such Superior Proposal (including the identity of the party making such Acquisition Proposal) and furnish to TriCo all the material terms and conditions of such proposal, and (C) prior to effecting such a Change in Recommendation, FNBB shall, and shall cause its financial and legal advisors to, during the period following FNBB’s delivery of the notice referred to in clause (B) above, negotiate with TriCo in good faith for a period of up to five (5) Business Days (to the extent TriCo desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal.

It is understood that and agreed that any amendment or modification to the financial or other material terms of the Acquisition Proposal giving rise to the FNBB’s notice of a Superior Proposal shall constitute a new Acquisition Proposal giving rise to a new obligation to provide notice and a new five (5) Business Day response period for TriCo, consequently extending the periods referenced in Sections 6.02(b)(iii) above.

Each of FNBB and TriCo further agrees that if such party shall become aware prior to the date of effectiveness of the Registration Statement of any information furnished by such party that would cause any of the statements in the Registration Statement or the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other parties thereof and to take the necessary steps to correct the Registration Statement or the Proxy Statement.

(e) No investigation by any of the parties or their respective representatives shall affect the representations, warranties, covenants or agreements of the other parties set forth herein.

6.07 No Solicitation; Acquisition Proposals.

(a) FNBB agrees that it shall, and shall direct and use its reasonable best efforts to cause its affiliates, directors, officers, employees, agents and representatives (including, without limitation, any investment banker, financial advisor, attorney, accountant or other representative retained by it) (all of the foregoing, collectively, “Representatives”) to, immediately cease any discussions or negotiations with any other parties that may be ongoing

-56-

with respect to the possibility or consideration of any Acquisition Proposal, and will use its reasonable best efforts to enforce any confidentiality or similar agreement relating to any Acquisition Proposal, including by requesting the other party to promptly return or destroy any confidential information previously furnished by or on behalf of FNBB or any of its Subsidiaries thereunder and by specifically enforcing the terms thereof in a court of competent jurisdiction. From the date of this Agreement through the Effective Time, neither FNBB nor any of its Subsidiaries shall, and shall cause their respective directors, officers or employees or any Representative retained by them not to, directly or indirectly through another Person, (i) solicit, initiate or encourage (including by way of furnishing information or assistance), or take any other action designed to facilitate or that is likely to result in, any inquiries or the making of any proposal or offer that constitutes, or is reasonably likely to lead to, any Acquisition Proposal, (ii) provide any confidential information or data to any Person relating to any Acquisition Proposal, (iii) participate in any discussions or negotiations regarding any Acquisition Proposal, (iv) waive, terminate, modify or fail to enforce any provision of any contractual “standstill” or similar obligations of any Person other than TriCo or its Affiliates, (v) approve or recommend, propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, asset purchase agreement or share exchange agreement, option agreement or other similar agreement related to any Acquisition Proposal or propose to do any of the foregoing, or (vi) make or authorize any statement, recommendation or solicitation in support of any Acquisition Proposal; provided, however, that prior to the date of the FNBB Meeting, if the FNBB Board determines in good faith, after consulting with its outside legal and financial advisors, that the failure to do so would breach, or would reasonably be expected to result in a breach of, the FNBB Board’s fiduciary duties under applicable law, FNBB may, in response to a bona fide, written Acquisition Proposal not solicited in violation of this Section 6.07(a) that the FNBB Board determines in good faith constitutes a Superior Proposal, subject to providing two (2) Business Days prior written notice of its decision to take such action to TriCo and identifying the Person making the proposal and all the material terms and conditions of such proposal and compliance with Section 6.07(b), (1) furnish information with respect to itself to any Person making such a Superior Proposal pursuant to a customary confidentiality agreement (as determined by FNBB after consultation with its outside counsel) on terms no more favorable to such Person than the terms contained in the Confidentiality Agreement are to TriCo, and (2) participate in discussions or negotiations regarding such a Superior Proposal. For purposes of this Agreement, the term “Acquisition Proposal” means any inquiry, proposal or offer, filing of any regulatory application or notice or disclosure of an intention to do any of the foregoing from any Person relating to any (w) direct or indirect acquisition or purchase of a business that constitutes 10% or more of the total revenues, net income, assets or deposits of FNBB and its Subsidiaries taken as a whole, (x) direct or indirect acquisition or purchase of any class of Equity Securities representing 10% or more of the voting power of FNBB or First National Bank, (y) tender offer or exchange offer that if consummated would result in any person beneficially owning 10% or more of any class of Equity Securities of FNBB or First National Bank or (z) merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving FNBB or First National Bank, other than the Transaction contemplated by this Agreement. For purposes of this Agreement, the term “Superior Proposal” means any bona fide written proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, for consideration consisting of cash and/or

-57-

securities, more than 50% of the combined voting power of the shares of FNBB Common Stock then outstanding or all or substantially all of FNBB’s consolidated assets, which the FNBB Board determines in good faith, after taking into account all legal, financial, regulatory and other aspects of the proposal and the person making the proposal (including any break-up fees, expense reimbursement provisions and conditions to consummation), and after consulting with FNBB’s financial advisor (which shall be a recognized investment banking firm) and outside counsel, (i) is more favorable from a financial point of view to its shareholders than the Transaction, (ii) is reasonably likely to be consummated on the terms set forth, and (iii) for which financing, to the extent required, is then committed or which, in the good faith judgment of the FNBB Board, is reasonably likely to be obtained by such third party.

(b) In addition to the obligations of FNBB set forth in Section 6.07(a), FNBB shall promptly (within 24 hours) advise TriCo orally and in writing of its receipt of any Acquisition Proposal and keep TriCo reasonably informed, on a current basis, of the continuing status thereof, including the material terms and conditions thereof and any material changes thereto, and shall contemporaneously provide to TriCo all materials provided to or made available to any third party pursuant to this Section 6.07 which were not previously provided to TriCo.

(c) FNBB agrees that any violation of the restrictions set forth in this Section 6.07 by any Representative of FNBB or its Subsidiaries shall be deemed a breach of this Section 6.07 by FNBB.

(d) Nothing contained in this Agreement shall prevent FNBB or the FNBB Board from complying with Rules 14d-9 and 14e-2 under the Exchange Act with respect to an Acquisition Proposal.

(e) The parties hereto agree that irreparable damage would occur in the event any of the restrictions set forth in Section 6.07(a) were violated by FNBB, its Subsidiaries or any Representative of FNBB or its Subsidiaries. It is accordingly agreed that TriCo shall be entitled to an injunction or injunctions to prevent breaches of Section 6.07 and to enforce specifically the terms and provisions thereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which TriCo is entitled at law or in equity. In the event attorneys’ fees or other costs are incurred to secure performance of any of the obligations herein provided for, or to establish damages for the breach thereof, or to obtain any other appropriate relief, whether by way of prosecution or defense, TriCo shall be entitled to recover reasonable attorneys’ fees and costs incurred therein.

6.08 Certain Policies. Prior to the Effective Date, upon the request of TriCo, FNBB shall, and shall cause its Subsidiaries to, consistent with GAAP and applicable banking laws and regulations, use their commercially reasonable best efforts to modify or change their 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 TriCo; provided, however, that no such modifications or changes need be made prior to the satisfaction of the conditions set forth in Section 7.01(b); and further provided that in any event, no such modification or change made by FNBB or any of its Subsidiaries pursuant to this Section 6.08 shall constitute or be deemed to be a breach, violation of or failure to satisfy any

-58-

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. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence of FNBB or its management with any such adjustments.

6.09 Nasdaq Listing. TriCo shall, as promptly as practicable, file all documents, take all actions reasonably necessary and otherwise use its commercially reasonable best efforts to list, prior to the Effective Date, on the Nasdaq the shares of TriCo Common Stock to be issued to the FNBB shareholders as the Merger Consideration.

6.10 Indemnification.

(a) From and after the Effective Time through the sixth (6^th) anniversary of the Effective Time, TriCo and the Surviving Corporation (each an “Indemnifying Party”) shall indemnify and hold harmless each present and former director, officer and employee of FNBB or First National Bank, as applicable, determined as of the Effective Time (the “Indemnified Parties”) against any 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 matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, arising in whole or in part out of or pertaining to the fact that he or she was a director, officer, employee, fiduciary or agent of FNBB or any FNBB Subsidiary or is or was serving at the request of FNBB or any FNBB Subsidiary as a director, officer, employee, fiduciary or agent of another corporation, partnership, joint venture, trust or other enterprise, including, without limitation, matters related to the negotiation, execution and performance of this Agreement or consummation of the Transaction, to the fullest extent which such Indemnified Parties would be entitled under the FNBB Articles and the FNBB Bylaws or, as applicable, the First National Bank Articles and the First National Bank Bylaws or any agreement, arrangement or understanding which has been set forth in Section 6.10 of FNBB’s Disclosure Schedule, in each case as in effect on the date hereof. TriCo shall also cause the Surviving Corporation to advance expenses as incurred by such Indemnified Parties to the same extent as such persons are entitled to advancement of expenses as of the date of this Agreement by FNBB pursuant to the FNBB Articles and the FNBB Bylaws or, as applicable, the First National Bank Articles or the First National Bank Bylaws or any agreement, arrangement or understanding which has been set forth in Section 6.10 of FNBB’s Disclosure Schedule, in each case as in effect on the date hereof.

(b) Any Indemnified Party wishing to claim indemnification under this Section 6.10, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify the Indemnifying Party, but the failure to so notify shall not relieve the Indemnifying Party of any liability it may have to such Indemnified Party if such failure does not actually prejudice the Indemnifying Party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) the Indemnifying Party shall have the right to assume the defense thereof and the Indemnifying Party shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense

-59-

thereof, except that if the Indemnifying Party elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise conflicts of interest between the Indemnifying Party and the Indemnified Parties that make joint representation inappropriate, the Indemnified Parties may retain counsel which is reasonably satisfactory to the Indemnifying Party, and the Indemnifying Party shall pay, promptly as statements therefor are received, the reasonable fees and expenses of such counsel for the Indemnified Parties (which may not exceed one firm in any jurisdiction unless the Indemnified Parties have conflicts of interest), (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) the Indemnifying Party shall not be liable for any settlement effected without its prior written consent, which shall not be unreasonably withheld, delayed or conditioned and (iv) the Indemnifying Party shall have no obligation hereunder in the event that a federal or state banking agency or a court of competent jurisdiction shall determine by final, non-appealable written order that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable laws and regulations.

(c) TriCo (and the Surviving Corporation) shall maintain FNBB’s existing directors’ and officers’ liability insurance policy (or provide a policy providing comparable coverage and amounts on terms no less favorable to the persons currently covered by FNBB’s existing policy, including TriCo’s existing policy if it meets the foregoing standard) covering persons who are currently covered by such insurance for a period of six (6) years after the Effective Time; provided, however, that in no event shall TriCo be obligated to expend, in order to maintain or provide insurance coverage pursuant to this Section 6.10(c), an amount in excess of two hundred percent (200%) of the annual premiums paid by FNBB as of the date hereof for such insurance (“Maximum Insurance Amount”); provided further, that if the amount of the annual premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Insurance Amount, TriCo shall obtain the most advantageous coverage obtainable for an annual premium equal to the Maximum Insurance Amount.

(d) If TriCo or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of TriCo shall assume the obligations set forth in this Section 6.10.

(e) The provisions of this Section 6.10 are (i) intended to be for the benefit of, and will be enforceable by, each Indemnified Party and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise.

6.11 Benefit Plans.

(a) As soon as administratively practicable after the Effective Time, TriCo shall take all reasonable action so that employees of FNBB and its Subsidiaries shall be entitled to participate in each TriCo Benefit Plan of general applicability to the same extent as similarly-situated employees of TriCo and its Subsidiaries (it being understood that inclusion of the employees of FNBB and its Subsidiaries in the TriCo Benefit Plans may occur at different times with respect to different plans), provided that coverage shall be continued under the

-60-

corresponding Benefit Plans of FNBB and its Subsidiaries until such employees are permitted to participate in the TriCo Benefit Plans and provided further, however, that nothing contained herein shall require TriCo or any of its Subsidiaries to make any grants to any former employee of FNBB and its Subsidiaries under any discretionary equity compensation plan of TriCo. TriCo shall cause each TriCo Benefit Plan in which employees of FNBB and its Subsidiaries are eligible to participate to recognize, for purposes of determining eligibility to participate in, the vesting of benefits and for all other purposes (but not for accrual of pension benefits, if applicable) under the TriCo Benefit Plans, the service of such employees with FNBB and its Subsidiaries to the same extent as such service was credited for such purpose by FNBB and its Subsidiaries, provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits or to the extent not otherwise permissible under the terms of a TriCo Benefit Plan, provide further, that an employee’s eligibility to participate will be governed by the eligibility criteria of the particular TriCo Benefit Plan. Nothing herein shall limit the ability of TriCo to amend or terminate any of the TriCo Benefit Plans or the FNBB Benefit Plans in accordance with their terms at any time.

(b) At and following the Effective Time, TriCo shall honor, and the Surviving Corporation shall continue to be obligated to perform, in accordance with their terms, all benefit obligations to, and contractual rights of, current and former employees of FNBB and its Subsidiaries and current and former directors of FNBB and its Subsidiaries existing as of the Effective Date, as well as all bonus, deferred compensation, supplemental retirement plan, salary continuation, severance, termination, change in control and other existing plans and policies of FNBB and its Subsidiaries to the extent that each of the foregoing are Previously Disclosed.

(c) At such time as employees of FNBB and its Subsidiaries become eligible to participate in a medical, dental, health, life or disability plan of TriCo or its Subsidiaries, TriCo shall cause each such plan to (i) waive any preexisting condition limitations to the extent such conditions are covered under the applicable medical, health or dental plans of TriCo, (ii) provide full credit under medical, health and dental plans for any deductibles, co-payment and out-of-pocket expenses incurred by the 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 a corresponding FNBB Benefit Plan prior to the Effective Time, provided, however, that such waiver shall not be required to the extent that such waiver would result in a duplication of benefits or to the extent not otherwise permissible under the terms of a contract insuring benefits under the TriCo Benefit Plans.

(d) Those employees of FNBB and its Subsidiaries (i) who are not offered employment by TriCo or its Subsidiaries following the Effective Time, who are not a party to an employment agreement or otherwise entitled to an existing severance package, change in control benefit or payments under any salary continuation plan, and who sign and deliver (and do not revoke) a termination and release agreement in a form acceptable to TriCo within forty-five (45) days of the Effective Time or (ii) who are terminated by TriCo without cause prior to the first anniversary of the Effective Time and deliver (and do not revoke) a termination and release agreement in a form acceptable to TriCo within forty-five (45) days of termination, shall be entitled to receive a single lump sum payment of severance in an amount and in accordance with

-61-

the terms of the severance policy set forth in Section 6.11(d) of FNBB’s Disclosure Schedule. If FNBB or any of its Subsidiaries has any other severance pay plan or arrangement, then any amounts paid pursuant to that plan or arrangement shall reduce the amount that the employee will receive under this Section 6.11(d) and in no event shall there be any duplication of severance pay. Nothing contained in this Section 6.11(d) hereof shall be construed or interpreted to limit or modify in any way TriCo’s or its Subsidiaries’ at will employment policy or provide any third party beneficiary rights to employees of FNBB or any of its Subsidiaries. In no event shall severance pay be taken into account in determining the amount of any other benefit (including but not limited to, an individual’s benefit under any retirement plan or policy). For purposes of this Section 6.11(d), “cause” shall mean the employee’s personal dishonesty, willful misconduct, breach of fiduciary duty involving personal profit, failure to comply with any valid and legal directive of TriCo, Tri Counties, FNBB and/or First National Bank failure to perform stated duties, violation of any law, rule or regulation (other than traffic violations or similar offenses) or order of any Governmental Entity.

(e) Prior to the Closing, FNBB shall have paid into the FNB Bancorp Savings Plan (the “FNBB Retirement Plan”) all discretionary employer contributions, including any employer matching contributions, profit sharing contributions or other non-elective contributions. Prior to the Closing, FNBB shall (i) adopt written resolutions (or take such other necessary or appropriate action), in form and substance reasonably acceptable to TriCo, to terminate the FNBB Retirement Plan in compliance with its terms and requirements of applicable law, effective no later than the Business Day preceding the Closing Date and (ii) provide for full vesting of all non-elective contributions under the FNBB Retirement Plan for all participants who currently maintain an account under the FNBB Retirement Plan, such termination and vesting to be effective no later than the Business Day preceding the Closing Date. FNBB shall provide TriCo with evidence of the termination of the FNBB Retirement Plan.

(f) Prior to December 31, 2017, FNBB shall freeze or amend each FNBB NQDP to close such plans to new participants and so that no participant may make any contribution after December 31, 2017.

(g) Each of FNBB and TriCo acknowledges and agrees that all provisions contained within this Section 6.11 with respect to Employees are included for the sole benefit of FNBB and nothing contained in this Section 6.11 shall confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 6.11. Nothing contained herein (i) shall be construed to establish, amend or modify any benefit plan, program or arrangement or (ii) alter or limit the ability of TriCo to amend, modify or terminate any benefit plan, program or arrangement at any time established, sponsored or maintained by TriCo or any of its Subsidiaries. Each of FNBB and TriCo agrees that the terms of this Section 6.11 do not and shall not create any right in any Person to continued employment with FNBB, TriCo or any of their respective Subsidiaries or to any compensation or benefit.

6.12 Appointment of Directors. TriCo agrees to take all action necessary to appoint or elect, effective as of the Effective Time, two individuals servings as directors of FNBB on the date of this Agreement, each of whom shall be mutually agreeable to TriCo and FNBB, as directors of each of TriCo and Tri Counties. Each individual shall serve until the first annual meeting of shareholders of TriCo following the Effective Time. Subject to the fiduciary duties of the TriCo Board, TriCo shall include such individuals on the list of nominees for director presented by the TriCo Board and for which the TriCo Board shall solicit proxies at the first annual meeting of shareholders of TriCo following the Effective Time.

-62-

6.13 Notification of Certain Matters. Each of FNBB and TriCo shall give prompt written notice to the other of any fact, event or circumstance known to it that (a) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (b) would cause or constitute a failure of any of the conditions provided for in Article VII.

6.14 Estoppel Letters. FNBB shall use its commercially reasonable efforts to obtain and deliver to TriCo at the Closing with respect to the real estate leased by FNBB or a FNBB Subsidiary, an estoppel letter from each of its lessors dated as of the Closing in substantially the form of Exhibit D attached hereto or such other form as may be reasonably acceptable to TriCo.

6.15 Antitakeover Statutes. Each of TriCo and FNBB and their respective Boards of Directors shall, if any state antitakeover statute or similar statute becomes applicable to this Agreement and the Transaction, take all action reasonably necessary to ensure that the Transaction may be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such statute or regulation on this Agreement and the Transaction.

6.16 Consents. FNBB shall, and shall cause its Subsidiaries to, use their commercially reasonable best efforts to obtain all consents, approvals, waivers, non-objections and to deliver any notices required pursuant to the terms of the Material Contracts as a result of the Transaction.

6.17 Exemption from Liability Under Section 16(b). Prior to the Effective Time, each of TriCo and FNBB shall take all steps as may be necessary or appropriate to cause any disposition of shares of FNBB Common Stock or conversion of any derivative securities in respect of such shares of FNBB Common Stock in connection with the consummation of the transactions contemplated by this Agreement to be exempt under Rule 16b-3 promulgated under the Exchange Act.

6.18 Federal Home Loan Bank Borrowings. FNBB shall cooperate with TriCo to effect the discharge of FNBB’s borrowings from the FHLB prior to the Effective Time.

6.19 Shareholder Litigation and Protests. FNBB shall promptly advise TriCo orally and in writing of any shareholder litigation or community-based protests against FNBB or its directors relating to this Agreement, the Merger, the Bank Merger or any of the other transactions contemplated hereby and shall keep TriCo fully informed regarding any such shareholder litigation or protests, including providing all relevant documentation. FNBB shall consult with TriCo and give good faith consideration of its comments and advice and give TriCo the opportunity to participate in the defense or settlement of any such litigation, provided that TriCo shall pay its own expenses, subject to applicable law. No settlement in connection with such litigation or protests shall be agreed to without TriCo’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

-63-

6.20 Closing Financial Statements. At least five (5) Business Days prior to the Effective Time of the Merger, FNBB shall provide TriCo with FNBB’s unaudited consolidated balance sheet and results of operations presenting the financial condition of FNBB and its Subsidiaries as of the close of business on the last day of the last month ended prior to the Effective Time of the Merger and for the period beginning on the first date of the then-current fiscal year through the close of business on the last day of the last month ended prior to the Effective Time of the Merger (the “Closing Financial Statements”); provided, however, that if the Effective Time of the Merger occurs on or before the fifth (5^th) Business Day of the month, the Closing Financial Statements shall instead be as of and through the end of the second (2^nd) month immediately preceding the Effective Time. The Closing Financial Statements shall be prepared in accordance with GAAP (excluding notes) and regulatory accounting principles and other applicable legal and accounting requirements, and shall reflect all period-end accruals and other adjustments, subject to the other requirements of this Agreement and shall also reflect accruals for all fees and expenses incurred or expected to be incurred in connection with the transactions contemplated in this Agreement (whether or not doing so is in accordance with GAAP).

(c) FNBB and TriCo agree that the agreement contained in paragraph (b) above is an integral part of the Transactions contemplated by this Agreement, that without such agreement TriCo would not have entered into this Agreement, and that such amount does not constitute a penalty or liquidated damages in the event of a breach of this Agreement by FNBB. If FNBB fails to pay TriCo the amount due under paragraph (b) above within the time periods specified in such paragraph (b), FNBB shall pay the costs and expenses (including reasonable legal fees and expenses) incurred by TriCo in connection with any action, including the filing of any lawsuit, taken to collect payment of such amount, provided TriCo prevails on the merits, together with interest on the amount of any such unpaid amount at the prime lending rate prevailing during such period as published in The Wall Street Journal, calculated on a daily basis from the date such amount was required to be paid until the date of actual payment.

Notwithstanding anything in the foregoing to the contrary, no representations, warranties, agreements and covenants contained in this Agreement shall be deemed to be terminated or extinguished so as to deprive a party hereto or any of its affiliates of any defense at law or in equity which otherwise would be available against the claims of any Person, including without limitation any shareholder or former shareholder.

9.08 Severability. Except to the extent that application of this Section 9.08 would have a Material Adverse Effect on FNBB or TriCo, 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. In all such cases, the parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision which, insofar as practicable, implements the original purposes and intents of this Agreement.

9.09 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. Except as provided in Section 8.02(b), 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. In the event attorneys’ fees or other costs are incurred to secure performance of any of the obligations herein provided for, or to establish damages for the breach thereof, or to obtain any other appropriate relief, whether by way of prosecution or defense, the prevailing party shall be entitled to recover reasonable attorneys’ fees and costs incurred therein.

9.10 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 reference purposes only and are not part of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” Whenever the words “as of the date hereof” are used in this Agreement, they shall be deemed to mean the day and year first above written.

9.11 Assignment. No party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

9.12 Alternative Structure. Notwithstanding any provision of this Agreement to the contrary, TriCo may at any time modify the structure of the acquisition of FNBB set forth herein, provided that (i) the Merger Consideration to be paid to the holders of FNBB Common Stock is not thereby changed in kind or reduced in amount as a result of such modification, (ii) such modifications will not adversely affect the tax treatment to FNBB’s shareholders as a result of receiving the Merger Consideration and (iii) such modification will not jeopardize receipt of any required approvals of Governmental Entities or materially delay consummation of the Transaction contemplated by this Agreement.

Notwithstanding the foregoing and for purposes of clarity, nothing herein shall prohibit Shareholder from exercising Shareholder’s discretion relating to Shareholder’s personal and business banking relationships; or

(iii) own, manage, operate, control, finance or participate in the ownership, management, operation, control or financing of, or be connected as an officer, director, employee, partner, principal, agent, representative, consultant or otherwise with, any business or enterprise engaged in any business that is competitive with or similar to FNBB’s Business within any of the California counties in which FNBB or its wholly-owned Subsidiaries does business or maintains an office as of the Closing Date. Notwithstanding the above, Shareholder shall not be deemed to be engaged directly or indirectly in any business in contravention of the immediately preceding sentence, if (a) Shareholder participates in any such business solely (i) as an officer or director of TriCo or Tri Counites or (ii) as a passive investor in up to 5% of the equity securities or 10% of the debt securities of a company or partnership, provided such securities are publicly traded or (b) Shareholder is employed by a business or enterprise that is engaged primarily in a business other than that which is competitive with or similar to the FNBB’s Business and Shareholder does not apply in any manner his or her expertise at such business or enterprise to that part of such business or enterprise that is competitive with or similar to FNBB’s Business. For purposes of this Agreement, “FNBB’s Business” means and includes (i) the origination, purchasing, selling and servicing of commercial, real estate, residential, construction, agricultural and consumer loans and/or (ii) the solicitation and provision of deposits, as conducted by FNBB and its wholly-owned Subsidiaries, in either event as conducted by FNBB or its wholly-owned subsidiaries as of the Closing Date[, provided this section 6(a)(iii) shall not apply if Shareholder continues to be employed as the Chief Financial Officer of FNBB at the effective time of the merger]. ¹

¹ This exception only applies to Xxxxx X. Xxxxxx, SVP, Chief Financial Officer.

A-4

(b) Without limiting the generality of the foregoing and at all times after the date hereof, other than for the benefit of TriCo, FNBB or their respective Subsidiaries, or as otherwise approved by TriCo, Shareholder (i) shall make no use of the Confidential Information, or any other part thereof, (ii) shall not disclose the Confidential Information, or any part thereof, to any other Person, and (iii) shall deliver, on and after the Effective Time of the Merger, upon the request of TriCo, all documents, reports, drawings, designs, plans, proposals and other tangible evidence of Confidential Information, now possessed or hereafter acquired by Shareholder, to TriCo.

(c) Shareholder acknowledges and agrees that the business conducted by FNBB and its wholly-owned Subsidiaries is highly competitive and that the covenants made by Shareholder in this Section 6 are made in connection with the disposition of Shareholder’s entire ownership interest in FNBB Common Stock, and are further made as a necessary inducement for TriCo to enter into the Merger Agreement and to consummate the transactions contemplated thereby. It is the desire and intent of the parties to this Agreement that the provisions of this Section 6 shall be enforced to the fullest extent permissible under the laws and public policies of each jurisdiction in which enforcement is sought. It is expressly understood and agreed that although Shareholder and TriCo each consider the restrictions contained in this Section 6 to be reasonable, if a final determination is made by a court of competent jurisdiction or an arbitrator that the time or territory or any other restriction contained in this Section 6 is unenforceable against any party, the provisions of this Section 6 shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable.

(d) Shareholder acknowledges and agrees that the provisions of this Agreement are necessary to protect TriCo’s legitimate business interests and to protect the value, including goodwill, of TriCo’s acquisition of FNBB. Shareholder warrants that these provisions will not unreasonably interfere with his or her ability to earn a living or to pursue his or her occupation and Shareholder has the means to support himself or herself and his or her dependents and the provisions of this Section 6 will not impair such ability in any manner whatsoever.

A-5

(e) Shareholder will not, at any time during the two-year period referred to in Subsection 6(a) of this Agreement, disparage TriCo, its Subsidiaries or any of its Affiliates, or the business conducted by TriCo, its Subsidiaries or any of their Affiliates, or any shareholder, member, director, manager, officer, employee or agent of TriCo, its Subsidiaries or any of their Affiliates.

7. Specific Performance and Remedies. Shareholder acknowledges that it will be impossible to measure in money the damage to TriCo if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, TriCo will not have an adequate remedy at law. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy, in addition to remedies at law or in damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that TriCo may have an adequate remedy at law. Shareholder agrees that he or she will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with TriCo’s seeking or obtaining such equitable relief.

8. Term of Agreement; Termination.

(a) The term of this Agreement shall commence on the date hereof.

(b) This Agreement shall terminate upon the date, if any, of the termination of the Merger Agreement in accordance with its terms. Upon any such termination, no party shall have any further obligations or liabilities hereunder; provided, however, such termination shall not relieve any party from liability for any willful breach of this Agreement prior to such termination. Notwithstanding the foregoing, in the event this Agreement is terminated prior to the Effective Time of the Merger, the provisions in Sections 6(a) (other than Section 6(a)(iii)) and 6(e) shall survive for a period of two (2) years from the date of termination (substituting the date of termination for the term “Closing Date” in such sections) and the provisions in Sections 3, 6(b) through 6(d), 7, 8 and 10 through 13 shall survive indefinitely.

9. Stop Transfer Order. In furtherance of this Agreement, Shareholder hereby authorizes and instructs FNBB to enter a stop transfer order with respect to all of Shareholder’s Shares for the period from the date hereof through the date this Agreement is terminated in accordance with Section 9, except as otherwise provided for in Section 2(a) hereof. FNBB agrees that it shall comply with such stop transfer instructions.

10. Entire Agreement. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provisions hereof by any party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

A-6

11. Notices. All notices, requests, claims, demands or other communications hereunder shall be in writing and shall be deemed given when delivered personally, upon receipt of a transmission confirmation if sent by telecopy or like transmission and on the next Business Day when sent by a reputable overnight courier service to the parties at the following addresses (or at such other address for a party as shall be specified by like notice):
