BUSINESS Information about TriCo Bancshares’ Business PART I TriCo Bancshares is a bank holding company incorporated in California in 1981 and registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). The Company’s principal subsidiary is Tri Counties Bank, a California-chartered commercial bank (the “Bank”). The Bank offers banking services to retail customers and small to medium-sized businesses through 57 traditional branches, 9 in-store branches and 2 loan production offices in northern and central California and had total assets of approximately $4.76 billion at December 31, 2017. The Bank’s deposits are insured by the Federal Deposit Insurance Corporation (the “FDIC”) up to applicable limits. See “Business of Tri Counties Bank”. The Company and the Bank are headquartered in Chico, California. As a bank holding company, TriCo is subject to the supervision of the Board of Governors of the Federal Reserve System (the “FRB”) under the BHC Act. The Bank is subject to the supervision of the California Department of Business Oversight (the “DBO”) and the FDIC. See “Regulation and Supervision.” TriCo has five capital trusts, which are all wholly-owned trust subsidiaries formed for the purpose of issuing trust preferred securities (“Trust Preferred Securities”) and lending the proceeds to TriCo. For more information regarding the trust preferred securities please refer to Note 17, “Junior Subordinated Debt” to the financial statements at Item 8 of this report. Additional information concerning the Company can be found on our website at www.tcbk.com. Copies of our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to these reports are available free of charge through the investors relations page of our website, www.tcbk.com, as soon as reasonably practicable after the Company files these reports with the U.S. Securities and Exchange Commission (“SEC”). The information on our website is not part this annual report. Business of Tri Counties Bank The Bank was incorporated as a California banking corporation on June 26, 1974, and received its certificate of authority to conduct banking operations on March 11, 1975. The Bank engages in the general commercial banking business in 26 counties in Northern and Central California. The Bank conducts a commercial banking business including accepting demand, savings and time deposits and making commercial, real estate, and consumer loans. It also offers installment note collection, issues cashier’s checks, sells travelers checks and provides safe deposit boxes and other customary banking services. Brokerage services are provided at the Bank’s offices by the Bank’s arrangement with Raymond James Financial Services, Inc., an independent financial services provider and broker-dealer. The Bank does not offer trust services or international banking services. The Bank has emphasized retail banking since it opened. Most of the Bank’s customers are retail customers and small to medium-sized businesses. The Bank emphasizes serving the needs of local businesses, farmers and ranchers, retired individuals and wage earners. The majority of the Bank’s loans are direct loans made to individuals and businesses in Northern and Central California where its branches are located. At December 31, 2017, the total of the Bank’s consumer loans net of deferred fees outstanding was $356,874,000 (11.8%), the total of commercial loans outstanding was $220,412,000 (7.3%), and the total of real estate loans including construction loans of $137,557,000 was $2,437,879,000 (80.9%). The Bank takes real estate, listed and unlisted securities, savings and time deposits, automobiles, machinery, equipment, inventory, accounts receivable and notes receivable secured by property as collateral for loans. Most of the Bank’s deposits are attracted from individuals and business-related sources. No single person or group of persons provides a material portion of the Bank’s deposits, the loss of any one or more of which would have a materially adverse effect on the business of the Bank, nor is a material portion of the Bank’s loans concentrated within a single industry or group of related industries. Proposed Merger with FNB Bancorp On December 11, 2017, the Company and FNB Bancorp (“FNBB”), entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) pursuant to which FNBB will be merged with and into TriCo, with TriCo as the surviving corporation (the “Merger”). The Merger Agreement provides that immediately after the Merger, FNBB’s bank subsidiary, First National Bank of Northern California (“First National Bank”), will merge with and into TriCo’s bank subsidiary, Tri Counties Bank, with Tri Counties Bank as the surviving bank (the “Bank Merger”). The Merger and Bank Merger are collectively referred to as the “Proposed Transaction.” 2 The Merger Agreement provides that each share of FNBB common stock issued and outstanding immediately prior to the effective time of the Merger will be canceled and converted into the right to receive 0.98 shares of TriCo common stock (the “Exchange Ratio”), with cash paid in lieu of fractional shares of TriCo common stock. Based on the closing price of TriCo common stock of $41.64 on December 8, 2017, the consideration value was $40.81 per share of FNBB common stock or approximately $315.3 million in aggregate. The value of the merger consideration will fluctuate until closing based on the value of TriCo’s stock and subject to a trading collar in certain circumstances. Upon consummation of the Merger, the shareholders of FNBB will own approximately 24% of the combined company. The consummation of the Merger is subject to a number of conditions, which include: (i) the approval of the Merger Agreement by FNBB’s shareholders and the approval of the Merger Agreement and the issuance of shares of TriCo common stock by TriCo’s shareholders; (ii) as of the closing of the Merger, FNBB shall have tangible common equity of not less than $119.0 million, subject to credit for certain merger-related expenses and certain assumptions and adjustments that are set forth in the Merger Agreement; (iii) the receipt of all necessary regulatory approvals for the Proposed Transaction, without the imposition of conditions or requirements that the TriCo Board of Directors reasonably determines in good faith would, individually or in the aggregate, materially reduce the economic benefits of the Proposed Transaction; (iv) the absence of any regulation, judgment, decree, injunction or other order of a governmental authority which prohibits the consummation of the Proposed Transaction or which prohibits or makes illegal the consummation of the Proposed Transaction; (v) the effective registration of the shares of TriCo Common Stock to be issued to FNBB’s shareholders with the Securities and Exchange Commission (the “SEC”) and the approval of such shares for listing on the Nasdaq Global Select Market; (vi) all representations and warranties made by TriCo and FNBB in the Merger Agreement must remain true and correct, except for certain inaccuracies that would not have, or would not reasonably be expected to have, a material adverse effect; and (vii) TriCo and FNBB must have performed their respective obligations under the Merger Agreement in all material respects. Acquisition of Three Branch Offices and Deposits from Bank of America On March 18, 2016, the Bank completed its acquisition of three branch banking offices from Bank of America originally announced October 28, 2015. The acquired branches are located in Arcata, Eureka and Fortuna in Humboldt County on the North Coast of California, and have significant overlap compared to the Company’s then-existing Northern California customer base and branch locations. As a result, these branch acquisitions create potential cost savings and future growth potential. With the levels of capital at the time, the acquisitions fit well into the Company’s growth strategy. Also on March 18, 2016, the electronic customer service and other data processing systems of the acquired branches were converted into the Bank’s systems, and the effect of revenue and expenses from the operations of the acquired branches are included in the results of the Company. The Bank paid a premium of $3,204,000 for deposit relationships with balances of $161,231,000 and loans with balances of $289,000, and received cash of $159,520,000 from Bank of America. The assets acquired and liabilities assumed in the acquisition of these branches were accounted for in accordance with ASC 805 “Business Combinations,” using the acquisition method of accounting and were recorded at their estimated fair values on the March 18, 2016 acquisition date, and the results of operations of the acquired branches are included in the Company’s consolidated statements of income since that date. The excess of the fair value of consideration transferred over total identifiable net assets was recorded as goodwill. The goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company and the acquired branches. $849,000 of the goodwill is deductible for income tax purposes because the acquisition was accounted for as a purchase of assets and assumption of liabilities for tax purposes. See Note 2 in the financial statements at Item 8 of this report for a discussion about this transaction. Other Activities The Bank may in the future engage in other businesses either directly or indirectly through subsidiaries acquired or formed by the Bank subject to regulatory constraints. See “Regulation and Supervision.” Employees At December 31, 2017, the Company employed 1,023 persons, including six executive officers. Full time equivalent employees were 985. No employees of the Company are presently represented by a union or covered under a collective bargaining agreement. Management believes that its employee relations are good. 3 Competition The banking business in California generally, and in the Bank’s primary service area of Northern and Central California specifically, is highly competitive with respect to both loans and deposits. It is dominated by a relatively small number of national and regional banks with many offices operating over a wide geographic area. Among the advantages such major banks have over the Bank is their ability to finance wide ranging advertising campaigns and to allocate their investment assets to regions of high yield and demand. By virtue of their greater total capitalization such institutions have substantially higher lending limits than does the Bank. In addition to competing with other banks, the Bank competes with savings institutions, credit unions and the financial markets for funds. Yields on corporate and government debt securities and other commercial paper may be higher than on deposits, and therefore affect the ability of commercial banks to attract and hold deposits. Commercial banks also compete for available funds with money market instruments and mutual funds. During past periods of high interest rates, money market funds have provided substantial competition to banks for deposits and they may continue to do so in the future. Mutual funds are also a major source of competition for savings dollars. The Bank relies substantially on local promotional activity, personal contacts by its officers, directors, employees and shareholders, extended hours, personalized service and its reputation in the communities it services to compete effectively. Regulation and Supervision General The Company and the Bank are subject to extensive regulation under both federal and state law. This regulation is intended primarily for the protection of depositors, the FDIC deposit insurance fund and the banking system as a whole, and not for the protection of shareholders of the Company. Set forth below is a summary description of the significant laws and regulations applicable to the Company and the Bank. The description is qualified in its entirety by reference to the applicable laws and regulations. Regulatory Agencies The Company is a legal entity separate and distinct from the Bank and its other subsidiaries. As a bank holding company, the Company is regulated under the BHC Act, and is subject to supervision, regulation and examination by the FRB. The Company is also under the jurisdiction of the SEC and is subject to the disclosure and regulatory requirements of the Securities Act of 1933 and the Securities Exchange Act of 1934, each administered by the SEC. The Company’s common stock is listed on the Nasdaq Global Select market (“Nasdaq”) under the trading symbol “TCBK” and the Company is, therefore, subject to the rules of Nasdaq for listed companies. The Bank, as a state chartered bank, is subject to broad federal regulation and oversight extending to all its operations by the FDIC and to state regulation by the DBO. The Dodd-Frank Act created the Consumer Financial Protection Bureau (the “CFPB”) as an independent entity with broad rulemaking, supervisory and enforcement authority over consumer financial products and services. The CFPB’s functions include investigating consumer complaints, rulemaking, supervising and examining bank consumer transactions, and enforcing rules related to consumer financial products and services. CFPB regulations and guidance apply to all financial institutions, including the Bank. Banks with $10 billion or more in assets are subject to examination by the CFPB. Banks with less than $10 billion in assets, including the Bank, continue to be examined for compliance with federal consumer laws by their primary federal banking agency. The Bank Holding Company Act The Company is registered as a bank holding company under the BHC Act. In general, the BHC Act limits the business of bank holding companies to banking, managing or controlling banks and other activities that the FRB has determined to be so closely related to banking as to be a proper incident thereto. As a bank holding company, TriCo is required to file reports with the FRB and the FRB periodically examines the Company. Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), a bank holding company is required to serve as a source of financial and managerial strength to its subsidiary bank and, under appropriate circumstances, to commit resources to support the subsidiary bank. Qualified bank holding companies that elect to be financial holding companies may engage in any activity, or acquire and retain the shares of a company engaged in any activity, that is either (i) financial in nature or incidental to such financial activity or (ii) complementary to a financial activity, and that does not pose a substantial risk to the safety and soundness of depository institutions or the financial system generally (as determined solely by the FRB). Activities that are financial in nature include securities underwriting and dealing, insurance underwriting and agency, and making merchant banking investments. The Company has not elected to become a financial holding company. 4 The BHC Act, the Bank Merger Act, and other federal and state statutes regulate acquisitions of commercial banks. The BHC Act requires the prior approval of the FRB for the direct or indirect acquisition of more than 5 percent of the voting shares of a commercial bank or its parent holding company. Under the Bank Merger Act, the prior approval of an acquiring bank’s primary federal regulator is required before it may merge with another bank or purchase the assets or assume the deposits of another bank. In reviewing applications seeking approval of merger and acquisition transactions, the bank regulatory authorities will consider, among other things, the competitive effect and public benefits of the transactions, the capital position of the combined organization, the applicant’s performance record under the Community Reinvestment Act, consumer compliance, fair housing laws and the effectiveness of the subject organizations in combating money laundering activities. Safety and Soundness Standards The Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”) implemented certain specific restrictions on transactions and required the regulators to adopt overall safety and soundness standards for depository institutions related to internal control, loan underwriting and documentation, and asset growth. Among other things, FDICIA limits the interest rates paid on deposits by undercapitalized institutions, the use of brokered deposits and the aggregate extension of credit by a depository institution to an executive officer, director, principal stockholder or related interest, and reduces deposit insurance coverage for deposits offered by undercapitalized institutions for deposits by certain employee benefits accounts. Section 39 to the Federal Deposit Insurance Act requires the agencies to establish safety and soundness standards for insured financial institutions covering: • • • • • • • • internal controls, information systems and internal audit systems; loan documentation; credit underwriting; interest rate exposure; asset growth; compensation, fees and benefits; asset quality, earnings and stock valuation; and excessive compensation for executive officers, directors or principal shareholders which could lead to material financial loss. If an agency determines that an institution fails to meet any standard established by the guidelines, the agency may require the financial institution to submit to the agency an acceptable plan to achieve compliance with the standard. If the agency requires submission of a compliance plan and the institution fails to timely submit an acceptable plan or to implement an accepted plan, the agency must require the institution to correct the deficiency. An institution must file a compliance plan within 30 days of a request to do so from the institution’s primary federal regulatory agency. The agencies may elect to initiate enforcement action in certain cases rather than rely on an existing plan particularly where failure to meet one or more of the standards could threaten the safe and sound operation of the institution. Restrictions on Dividends and Distributions A California corporation such as TriCo may make a distribution to its shareholders to the extent that either the corporation’s retained earnings meet or exceed the amount of the proposed distribution or the value of the corporation’s assets exceed the amount of its liabilities plus the amount of shareholders preferences, if any, and certain other conditions are met. It is the FRB’s policy that bank holding companies should generally pay dividends on common stock only out of income available over the past year, and only if prospective earnings retention is consistent with the organization’s expected future needs and financial condition. The primary source of funds for payment of dividends by TriCo to its shareholders has been and will be the receipt of dividends and management fees from the Bank. TriCo’s ability to receive dividends from the Bank is limited by applicable state and federal law. Under the California Financial Code, funds available for cash dividend payments by a bank are restricted to the lesser of: (i) retained earnings or (ii) the bank’s net income for its last three fiscal years (less any distributions to shareholders made during such period). However, with the prior approval of the Commissioner of the DBO, a bank may pay cash dividends in an amount not to exceed the greatest of the: (1) retained earnings of the bank; (2) net income of the bank for its last fiscal year; or (3) net income of the bank for its current fiscal year. However, if the DBO finds that the shareholders’ equity of the bank is not adequate or that the payment of a dividend would be unsafe or unsound, the Commissioner may order the bank not to pay a dividend to shareholders. Additionally, under FDICIA, a bank may not make any capital distribution, including the payment of dividends, if after making such distribution the bank would be in any of the “undercapitalized” categories under the FDIC’s Prompt Corrective Action regulations. A bank is undercapitalized for this purpose if its leverage ratios, Tier 1 risk-based capital level and total risk-based capital ratio are not at least four percent, four percent and eight percent, respectively. 5 The FRB, FDIC and the DBO have authority to prohibit a bank holding company or a bank from engaging in practices which are considered to be unsafe and unsound. Depending on the financial condition of TriCo and the Bank and other factors, the FRB, FDIC or the DBO could determine that payment of dividends or other payments by TriCo or the Bank might constitute an unsafe or unsound practice. The Community Reinvestment Act The Community Reinvestment Act of 1977 (“CRA”) requires the federal banking regulatory agencies to periodically assess a bank’s record of helping meet the credit needs of its entire community, including low- and moderate-income neighborhoods. The CRA also requires the agencies to consider a financial institution’s record of meeting its community credit when evaluating applications for, among other things, domestic branches and mergers or acquisitions. The federal banking agencies rate depository institutions’ compliance with the CRA. The ratings range from a high of “outstanding” to a low of “substantial noncompliance.” A less than “satisfactory” rating could result in the suspension of any growth of the Bank through acquisitions or opening de novo branches until the rating is improved. As of its most recent CRA examination, the Bank’s CRA rating was “Satisfactory.” Consumer Protection Laws The Bank is subject to many federal consumer protection statues and regulations, some of which are discussed below. • • • • • The Equal Credit Opportunity Act generally prohibits discrimination in any credit transaction, whether for consumer or business purposes, on the basis of race, color, religion, national origin, sex, marital status, age (except in limited circumstances), receipt of income from public assistance programs, or good faith exercise of any rights under the Consumer Credit Protection Act. The Truth-in-Lending Act is designed to ensure that credit terms are disclosed in a meaningful way so that consumers may compare credit terms more readily and knowledgeably. The Fair Housing Act regulates many practices, including making it unlawful for any lender to discriminate in its housing- related lending activities against any person because of race, color, religion, national origin, sex, handicap or familial status. The Home Mortgage Disclosure Act, which includes a “fair lending” aspect, requires the collection and disclosure of data about applicant and borrower characteristics as a way of identifying possible discriminatory lending patterns and enforcing anti-discrimination statutes. The Real Estate Settlement Procedures Act requires lenders to provide borrowers with disclosures regarding the nature and cost of real estate settlements and prohibits certain abusive practices, such as kickbacks, and places limitations on the amount of escrow accounts. In addition, the CFPB has taken a number of actions that may affect the Bank’s operations and compliance costs, including the following: • • The issuance of final rules for residential mortgage lending, which became effective January 10, 2013, including definitions for “qualified mortgages” and detailed standards by which lenders must satisfy themselves of the borrower’s ability to repay the loan and revised forms of disclosure under the Truth in Lending Act and the Real Estate Settlement Procedures Act The issuance of a policy report on arbitration clauses which could result in the restriction or prohibition of lenders including arbitration clauses in consumer financial services contracts. • Actions taken to regulate and supervise credit bureaus and debt collections. • Positions taken by CFPB on fair lending, including applying the disparate impact theory in auto financing, which could make it harder for lenders, such as the Bank, to charge different rates or apply different terms to loans to different customers. Penalties for violations of the above laws may include fines, reimbursements, injunctive relief and other penalties. Data Privacy and Cyber Security Regulation The Company is subject to many U.S. federal, state and international laws and regulations governing requirements for maintaining policies and procedures to protect the non-public confidential information of customers and employees. The privacy provisions of the Gramm-Leach-Bliley Act generally prohibit financial institutions, including the Company, from disclosing nonpublic personal financial information of consumer customers to third parties for certain purposes (primarily marketing) unless customers have the opportunity to “opt out” of the disclosure. Other laws and regulations, at the international, federal and state level, limit the Company’s ability to share certain information with affiliates and non-affiliates for marketing and/or non-marketing purposes, or to contact customers with marketing offers. The Gramm-Leach-Bliley Act 6 also requires banks to implement a comprehensive information security program that includes administrative, technical and physical safeguards to ensure the security and confidentiality of customer records and information. Regulatory Capital Requirements The Company and the Bank are subject to the minimum capital requirements of the FDIC and the FRB, respectively. Capital requirements may have an effect on the Company’s and the Bank’s profitability and ability to pay dividends. If the Company or the Bank lacks adequate capital to increase its assets without violating the minimum capital requirements or if it forced to reduce the level of its assets in order to satisfy regulatory capital requirements, its ability to generate earnings would be reduced. The Company’s and the Bank’s primary federal regulators, the FRB and the FDIC, have adopted guidelines utilizing a risk-based capital structure. Under the risk-based capital rules applicable through December 31, 2014, banking organizations were required to maintain minimum ratios of Tier 1 capital and total capital to total risk- weighted assets (including certain off- balance sheet items, such as letters of credit). Qualifying capital is divided into two tiers. Tier 1 capital consists generally of common stockholders’ equity, retained earnings, qualifying noncumulative perpetual preferred stock, a limited amount of qualifying cumulative perpetual preferred stock (at the holding company level) and minority interests in the equity accounts of consolidated subsidiaries, less goodwill and certain other intangible assets. Tier 2 capital consists of, among other things, allowance for loan and lease losses up to 1.25% of weighted risk assets, other perpetual preferred stock, hybrid capital instruments, perpetual debt, mandatory convertible debt, subordinated debt and intermediate-term preferred stock, subject to limitations. Tier 2 capital qualifies as part of total capital up to a maximum of 100% of Tier 1 capital. Under these risk-based capital guidelines, the Company is required to maintain total capital equal to at least 8% of its assets, of which at least 4% must be in the form of Tier 1 capital. In addition, the Bank is subject to minimum capital ratios under the regulatory framework for prompt corrective action discussed below under “— Prompt Corrective Action.” The Company and the Bank are also required to maintain a minimum leverage ratio of 4% of Tier 1 capital to total assets (the “leverage ratio”). The leverage ratio is determined by dividing an institution’s Tier 1 capital by its quarterly average total assets, less goodwill and certain other intangible assets. The minimum leverage ratio constitutes a minimum requirement for the most well-run banking organizations. See Note 29 in the financial statements at Item 8 of this report for a discussion about the Company’s risk-based capital and leverage ratios. In July, 2013, the federal banking agencies approved new capital rules implementing the “Basel III” regulatory capital reforms and other changes required by the Dodd-Frank Act. “Basel III” refers to capital guidelines adopted by the Basel Committee on Banking Supervision, which is a committee of central banks and bank supervisors/regulators from the major industrialized countries. The new capital rules include new risk-based capital and leverage ratios, which are being phased in from 2015 to 2019, and which refine the definition of what constitutes “capital” for purposes of calculating those ratios. The new minimum capital level requirements applicable to the Company and the Bank as of January 1, 2015 under the new capital rules included: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6% (increased from 4%); (iii) a total capital ratio of 8% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The new capital rules also establish a “capital conservation buffer” above the new regulatory minimum capital requirements, which must consist entirely of common equity Tier 1 capital. The capital conservation buffer is to be phased-in over four years beginning on January 1, 2016, as follows: The buffer will be 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. This will result in the following minimum ratios beginning in 2019 (inclusive of the buffer): (i) a common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%, and (iii) a total capital ratio of 10.5%. Under the new capital rules, institutions are subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its common equity capital level falls below the buffer amount. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions. The new capital rules provide regulators discretion to impose an additional capital buffer, the “countercyclical buffer,” of up to 2.5% of common equity Tier 1 capital to take into account the macro-financial environment and periods of excessive credit growth. However, the countercyclical buffer only applies to larger banks with $250 billion or more in total assets or $10 billion or more in total foreign exposures and is not expected to have an impact on the Company or the Bank. The new capital rules also implement revisions and clarifications consistent with Basel III regarding the various components of Tier 1 capital, including common equity, unrealized gains and losses, as well as certain instruments including trust preferred securities that will no longer qualify as Tier 1 capital, some of which will be phased out over time. However, the new capital rules provide that depository institution holding companies with less than $15 billion in total assets as of December 31, 2009, such as the Company, will be able to continue to include non-qualifying instruments that were issued and included in Tier 1 capital prior to May 19, 2010, such as the Company’s Trust Preferred Securities, as Tier 1. This treatment is grandfathered and will apply even if the Company exceeds $15 billion assets due to organic growth. However, if the Company exceeds $15 billion in assets as the result of a merger or acquisition, then the Tier 1 treatment of its outstanding trust preferred securities will be phased out but may still be treated as Tier 2 capital. 7 The new capital rules also include changes for the calculation of risk-weighted assets, which are being phased in beginning January 1, 2015. The new capital rules utilizes an increased number of credit risk exposure categories and risk weights, and also addresses: (i) an alternative standard of creditworthiness consistent with Section 939A of the Dodd-Frank Act; (ii) revisions to recognition of credit risk mitigation; (iii) rules for risk weighting of equity exposures and past due loans; (iv) revised capital treatment for derivatives and repo- style transactions; and (v) disclosure requirements for top-tier banking organizations with $50 billion or more in total assets that are not subject to the “advance approach rules” that apply to banks with greater than $250 billion in consolidated assets. We believe that we were in compliance with the requirements applicable to us as set forth in the new capital rules as of December 31, 2017. Prompt Corrective Action Prompt Corrective Action regulations of the federal bank regulatory agencies establish five capital categories in descending order (well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized), assignment to which depends upon the institution’s total risk-based capital ratio, Tier 1 risk-based capital ratio, and leverage ratio. The new capital rules revised the prompt corrective action framework. Under the new prompt corrective action framework, which implements the new capital rules, insured depository institutions will be required to meet the following increased capital level requirements in order to qualify as “well capitalized:” (i) a new common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8% (increased from 6%); (iii) a total capital ratio of 10% (unchanged from current rules); and (iv) a Tier 1 leverage ratio of 5% (increased from 4%). Institutions classified in one of the three undercapitalized categories are subject to certain mandatory and discretionary supervisory actions, which include increased monitoring and review, implementation of capital restoration plans, asset growth restrictions, limitations upon expansion and new business activities, requirements to augment capital, restrictions upon deposit gathering and interest rates, replacement of senior executive officers and directors, and requiring divestiture or sale of the institution. The Bank’s capital levels have exceeded the amounts necessary to be considered well capitalized under the current regulatory framework for prompt corrective action since its adoption. Deposit Insurance Deposit accounts in the Bank are insured by the FDIC, generally up to a maximum of $250,000 per separately insured depositor. The Bank pays deposit insurance assessments based on its consolidated total assets less tangible equity capital. The assessment rate is based on the risk category of the institution. To determine the total base assessment rate, the FDIC first establishes an institution’s initial base assessment rate and then adjusts the initial base assessment based upon an institution’s levels of unsecured debt, secured liabilities, and brokered deposits. The total base assessment rate ranges from 2.5 to 45 basis points of the institution’s average consolidated total assets less tangible equity capital. The Bank is generally unable to control the amount of premiums that it is required to pay for FDIC insurance. If there are additional bank or financial institution failures or if the FDIC otherwise determines, the Bank may be required to pay even higher FDIC premiums than the recently increased levels. Increases in FDIC insurance premiums may have a material and adverse effect on the Company’s earnings and could have a material adverse effect on the value of, or market for, the Company’s common stock. The FDIC may terminate a depository institution’s deposit insurance upon a finding that the institution’s financial condition is unsafe or unsound or that the institution has engaged in unsafe or unsound practices that pose a risk to the DIF or that may prejudice the interest of the bank’s depositors. The termination of deposit insurance for the Bank would also result in the revocation of the Bank’s charter by the DBO. Interstate Branching The Dodd-Frank Act authorized national and state banks to establish branches in other states to the same extent as a bank chartered by that state would be permitted to branch. Previously, banks could only establish branches in other states if the host state expressly permitted out-of-state banks to establish branches in that state. Accordingly, banks will be able to enter new markets more freely. Anti-Money Laundering Laws A series of banking laws and regulations beginning with the bank Secrecy Act in 1970 requires banks to prevent, detect, and report illicit or illegal financial activities to the federal government to prevent money laundering, international drug trafficking, and terrorism. Under the USA Patriot Act of 2001, financial institutions are subject to prohibitions against specified financial transactions and account relationships, requirements regarding the Customer Identification Program, as 8 well as enhanced due diligence and “know your customer” standards in their dealings with high risk customers, foreign financial institutions, and foreign individuals and entities. Transactions with Affiliates Banks are also subject to certain restrictions imposed by the Federal Reserve Act on extensions of credit to executive officers, directors, principal shareholders (including the Company) or any related interest of such persons. Extensions of credit must be made on substantially the same terms, including interest rates and collateral as, and follow credit underwriting procedures that are not less stringent than, those prevailing at the time for comparable transactions with persons not affiliated with the bank, and must not involve more than the normal risk of repayment or present other unfavorable features. Banks are also subject to certain lending limits and restrictions on overdrafts to such persons. Regulation W requires that certain transactions between the Bank and its affiliates, including its holding company, be on terms substantially the same, or at least as favorable to the Bank, as those prevailing at the time for comparable transactions with or involving nonaffiliated companies or, in the absence of comparable transactions, on terms and under circumstances, including credit standards, that in good faith would be offered to or would apply to nonaffiliated companies. Impact of Monetary Policies Banking is a business that depends on interest rate differentials. In general, the difference between the interest paid by a bank on its deposits and other borrowings, and the interest rate earned by banks on loans, securities and other interest-earning assets comprises the major source of banks’ earnings. Thus, the earnings and growth of banks are subject to the influence of economic conditions generally, both domestic and foreign, and also to the monetary and fiscal policies of the United States and its agencies, particularly the FRB. The FRB implements national monetary policy, such as seeking to curb inflation and combat recession, by its open-market dealings in United States government securities, by adjusting the required level of reserves for financial institutions subject to reserve requirements and through adjustments to the discount rate applicable to borrowings by banks which are members of the FRB. The actions of the FRB in these areas influence the growth of bank loans, investments and deposits and also affect interest rates. The nature and timing of any future changes in such policies and their impact on the Company cannot be predicted. In addition, adverse economic conditions could make a higher provision for loan losses a prudent course and could cause higher loan loss charge-offs, thus adversely affecting the Company’s net earnings. ITEM 1A. RISK FACTORS There are a number of factors that may adversely affect the Company’s business, financial results, or stock price. Information concerning additional risk factors related to the proposed merger of the Company and FNB Bancorp is available in the Company’s registration statement on Form S-4 SEC to be filed with the SEC. In analyzing whether to make or continue holding an investment in the Company, investors should consider, among other factors, the following: Risks Related to the Nature and Geographic Area of Our Business We are exposed to risks in connection with the loans we make. As a lender, we face a significant risk that we will sustain losses because borrowers, guarantors and related parties may fail to perform in accordance with the terms of the loans we make or acquire. Our earnings are significantly affected by our ability to properly originate, underwrite and service loans. We have underwriting and credit monitoring procedures and credit policies, including the establishment and review of the allowance for loan losses, that we believe appropriately address this risk by assessing the likelihood of nonperformance, tracking loan performance and diversifying our respective loan portfolios. Such policies and procedures, however, may not prevent unexpected losses that could adversely affect our results of operations. We could sustain losses if we incorrectly assess the creditworthiness of our borrowers or fail to detect or respond to deterioration in asset quality in a timely manner. Our allowance for loan losses may not be adequate to cover actual losses. Like other financial institutions, we maintain an allowance for loan losses to provide for loan defaults and non-performance. Our allowance for loan losses may not be adequate to cover actual loan losses, and future provisions for loan losses would reduce our earnings and could materially and adversely affect our business, financial condition, results of operations and cash flows. The allowance for loan losses reflects our estimate of the probable incurred losses in our loan portfolio at the relevant balance sheet date. Our allowance for loan losses is based on prior experience, as well as an evaluation of the known risks in the current portfolio, composition and growth of the loan portfolio and economic factors. Determining an appropriate level of loan loss allowance is an inherently difficult process and is based on numerous assumptions. The amount of future losses is susceptible to changes in economic, operating and other conditions, including changes in interest rates, that may be beyond our control and these losses may exceed current estimates. Federal and state regulatory agencies, as an integral part of their examination process, review our loans and allowance for loan losses. While we believe that our allowance for loan losses is 9 adequate to cover current losses, we cannot assure you that we will not increase the allowance for loan losses further or that the allowance will be adequate to absorb loan losses we actually incur. Either of these occurrences could have a material adverse effect on our business, financial condition and results of operations. 10 Our business may be adversely affected by business conditions in northern and central California. We conduct most of our business in northern and central California. As a result of this geographic concentration, our financial results may be impacted by economic conditions in California. Deterioration in the economic conditions in California could result in the following consequences, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows: • • • • problem assets and foreclosures may increase, demand for our products and services may decline, low cost or non-interest bearing deposits may decrease, and collateral for loans made by us, especially real estate, may decline in value, in turn reducing customers’ borrowing power, and reducing the value of assets and collateral associated with our existing loans. In view of the concentration of our operations and the collateral securing our loan portfolio in both northern and central California, we may be particularly susceptible to the adverse effects of any of these consequences, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows. A significant majority of the loans in our portfolio are secured by real estate and a downturn in our real estate markets could hurt our business. A downturn in our real estate markets in which we conduct our business in California could hurt our business because most of our loans are secured by real estate. Real estate values and real estate markets are generally affected by changes in national, regional or local economic conditions, fluctuations in interest rates and the availability of loans to potential purchasers, changes in tax laws and other governmental statutes, regulations and policies and acts of nature. As real estate prices decline, the value of real estate collateral securing our loans is reduced. As a result, our ability to recover on defaulted loans by foreclosing and selling the real estate collateral could then be diminished and we would be more likely to suffer losses on defaulted loans. As of December 31, 2017, approximately 91.9% of the book value of our loan portfolio consisted of loans collateralized by various types of real estate. Substantially all of our real estate collateral is located in California. So if there is a significant adverse decline in real estate values in California, the collateral for our loans will provide less security. Real estate values could also be affected by, among other things, earthquakes, drought and national disasters in our markets. Any such downturn could have a material adverse effect on our business, financial condition, results of operations and cash flows. We depend on key personnel and the loss of one or more of those key personnel may materially and adversely affect our prospects. Competition for qualified employees and personnel in the banking industry is intense and there are a limited number of qualified persons with knowledge of, and experience in, the California community banking industry. The process of recruiting personnel with the combination of skills and attributes required to carry out our strategies is often lengthy. Our success depends to a significant degree upon our ability to attract and retain qualified management, loan origination, finance, administrative, marketing and technical personnel and upon the continued contributions of our management and personnel. In particular, our success has been and continues to be highly dependent upon the abilities of our senior management team of Messrs. Smith, Bailey, Carney, Fleshood, O’Sullivan and Reddish, who have expertise in banking and collective experience in the California markets we serve and have targeted for future expansion. We also depend upon a number of other key executives who are California natives or are long-time residents and who are integral to implementing our business plan. The loss of the services of any one of our senior executive management team or other key executives could have a material adverse effect on our business, financial condition, results of operations and cash flows. We are exposed to the risk of environmental liabilities with respect to properties to which we take title. In the course of our business, we may foreclose and take title to real estate and could be subject to environmental liabilities with respect to these properties. We may be held liable to a governmental entity or to third parties for property damage, personal injury, investigation and clean-up costs incurred by these parties in connection with environmental contamination, or may be required to investigate or clean-up hazardous or toxic substances, or chemical releases at a property. The costs associated with investigation or remediation activities could be substantial. In addition, if we are the owner or former owner of a contaminated site, we may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property. If we become subject to significant environmental liabilities, our business, financial condition, results of operations and cash flows could be materially adversely affected. Strong competition in California could hurt our profits. Competition in the banking and financial services industry is intense. Our profitability depends upon our continued ability to successfully compete. We primarily compete in northern and central California for loans, deposits and 11 customers with commercial banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage firms and Internet-based marketplace lending platforms. In particular, our competitors include major financial companies whose greater resources may afford them a marketplace advantage by enabling them to maintain numerous locations and mount extensive promotional and advertising campaigns. Additionally, banks and other financial institutions with larger capitalization and financial intermediaries not subject to bank regulatory restrictions may have larger lending limits which would allow them to serve the credit needs of larger customers. Areas of competition include interest rates for loans and deposits, efforts to obtain loan and deposit customers and a range in quality of products and services provided, including new technology-driven products and services. Technological innovation continues to contribute to greater competition in domestic and international financial services markets as technological advances enable more companies, such as Internet-based marketplace lenders, to provide financial services, often without many of regulatory and capital restrictions that we face. We also face competition from out-of-state financial intermediaries that have opened loan production offices or that solicit deposits in our market areas. If we are unable to attract and retain banking customers, we may be unable to continue our loan growth and level of deposits and our business, financial condition, results of operations and cash flows may be adversely affected. Our previous results may not be indicative of our future results. We may not be able to sustain our historical rate of growth and level of profitability or may not even be able to grow our business or continue to be profitable at all. Various factors, such as economic conditions, regulatory and legislative considerations and competition, may also impede or prohibit our ability to expand our market presence and financial performance. If we experience a significant decrease in our historical rate of growth, our results of operations and financial condition may be adversely affected due to a high percentage of our operating costs being fixed expenses. We may be adversely affected by the soundness of other financial institutions. Financial services institutions are interrelated as a result of clearing, counterparty, or other relationships. We have exposure to many different industries and counterparties, and routinely execute transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, and other institutional clients. Many of these transactions expose us to credit risk in the event of a default by a counterparty or client. In addition, our credit risk may be exacerbated when the collateral that we hold cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the credit or derivative exposure due to us. Any such losses could have a material adverse effect on our financial condition and results of operations. Severe weather, natural disasters and other external events could adversely affect our business. Our operations and our customer base are primarily located in northern and central California where natural and other disasters may occur. These regions are known for being vulnerable to natural disasters and other risks, such as earthquakes, fires, droughts and floods, the nature and severity of which may be impacted by climate change. These types of natural catastrophic events have at times disrupted the local economies, our business and customers in these regions. Such events could also affect the stability of the Bank’s deposit base; impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans and cause significant property damage, result in losses of revenue and/or cause us to incur additional expenses. In addition, catastrophic events occurring in other regions of the world may have an impact on our customers and in turn, on us. Our business continuity and disaster recovery plans may not be successful upon the occurrence of one of these scenarios, and a significant catastrophic event anywhere in the world could materially adversely affect our operating results. The impacts of recent tax reform are not yet fully known, and these and other tax regulations could be subject to potential legislative, administrative or judicial changes or interpretations. The tax reform bill enacted on December 22, 2017 has had, and is expected to continue to have, far-reaching and significant effects on us, our customers and the U.S. economy. The tax reform bill lowered the corporate federal statutory tax rate and eliminated or limited certain federal corporate deductions. It is too early to evaluate all of the potential consequences of the tax reform bill, but such consequences could include lower commercial customer borrowings, either due to the increase in cash flows as a result of the reduction in the corporate statutory tax rate or the utilization by businesses in certain sectors of alternative non-debt financing and/or early retirement of existing debt. Further, there can be no assurance that any benefits realized by us as a result of the reduction in the corporate federal statutory tax rate will ultimately result in increased net income, whether due to decreased loan yields as a result of competition or to other factors. Uncertainty also exists related to state and other taxing jurisdictions’ response to federal tax reform, which will continue to be monitored and evaluated. Federal income tax treatment of corporations may be further clarified and modified by other legislative, administrative or judicial changes or interpretations at any time. Any such changes could adversely affect us. 12 Market and Interest Rate Risk Fluctuations in interest rates could reduce our profitability and affect the value of our assets. Like other financial institutions, we are subject to interest rate risk. Our primary source of income is net interest income, which is the difference between interest earned on loans and leases and investments, and interest paid on deposits and borrowings. We expect that we will periodically experience imbalances in the interest rate sensitivities of our assets and liabilities and the relationships of various interest rates to each other. Over any defined period of time, our interest-earning assets may be more sensitive to changes in market interest rates than our interest-bearing liabilities, or vice-versa. In addition, the individual market interest rates underlying our loan and lease and deposit products may not change to the same degree over a given time period. If market interest rates should move contrary to our position, earnings may be negatively affected. In addition, loan and lease volume and quality and deposit volume and mix can be affected by market interest rates as can the businesses of our clients. Changes in levels of market interest rates could have a material adverse effect on our net interest spread, asset quality, origination volume, and overall profitability. Market interest rates are beyond our control, and they fluctuate in response to general economic conditions and the policies of various governmental and regulatory agencies, in particular, the Federal Reserve Board. Changes in monetary policy, including changes in interest rates, may negatively affect our ability to originate loans and leases, the value of our assets and our ability to realize gains from the sale of our assets, all of which ultimately could affect our earnings. Our business is subject to interest rate risk and variations in interest rates may negatively affect our financial performance. Because of the differences in the maturities and repricing characteristics of our interest-earning assets and interest-bearing liabilities, changes in interest rates do not produce equivalent changes in interest income earned on interest-earning assets and interest paid on interest-bearing liabilities. Accordingly, fluctuations in interest rates could adversely affect our interest rate spread and, in turn, our profitability. In addition, loan origination volumes are affected by market interest rates. Rising interest rates, generally, are associated with a lower volume of loan originations while lower interest rates are usually associated with higher loan originations. Conversely, in rising interest rate environments, loan repayment rates may decline and in falling interest rate environments, loan repayment rates may increase. Although we were successful in generating new loans during 2017, the continuation of historically low long-term interest rate levels may cause additional refinancing of commercial real estate and 1-4 family residence loans, which may depress our loan volumes or cause rates on loans to decline. In addition, an increase in the general level of short-term interest rates on variable rate loans may adversely affect the ability of certain borrowers to pay the interest on and principal of their obligations or reduce the amount they wish to borrow. Additionally, if short-term market rates rise, in order to retain existing deposit customers and attract new deposit customers we may need to increase rates we pay on deposit accounts. Accordingly, changes in levels of market interest rates could materially and adversely affect our net interest spread, asset quality, loan origination volume, business, financial condition, results of operations and cash flows. Regulatory Risks Recently enacted financial reform legislation has, among other things, created a new Consumer Financial Protection Bureau, tightened capital standards and resulted in new laws and regulations that are expected to increase our costs of operations. The Dodd-Frank Act, which was enacted in 2010, significantly changed the current bank regulatory structure and affects the lending, deposit, investment, trading and operating activities of financial institutions and their holding companies. Among other things, the Dodd-Frank Act created a new Consumer Financial Protection Bureau with broad powers to supervise and enforce consumer protection laws. The CFPB has broad rule-making authority for a wide range of consumer protection laws that apply to all banks and savings institutions, including the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB has examination and enforcement authority over all banks and savings institutions with more than $10 billion in assets. Banks with $10 billion or less in assets, such as the Bank, are subject to the CFPB’s rules but continue to be examined for compliance with the consumer laws by their primary bank regulators. In addition, the Dodd-Frank Act required the FDIC and FRB to adopt new, more stringent capital rules that apply to us. The Dodd-Frank Act also weakens the federal preemption rules that have been applicable for national banks and federal savings associations, and gives state attorneys general the ability to enforce federal consumer protection laws. It is difficult to predict the continuing impact that the Dodd-Frank Act and the yet to be written implementing rules and regulations will have on community banks. However, it is expected that at a minimum they will increase our operating and compliance costs and could increase our interest expense. 13 We operate in a highly regulated environment and we may be adversely affected by new laws and regulations or changes in existing laws and regulations. Regulations may prevent or impair our ability to pay dividends, engage in acquisitions or operate in other ways. We are subject to extensive regulation, supervision and examination by the DBO, FDIC, and the FRB. See Item 1 - Regulation and Supervision of this report for information on the regulation and supervision which governs our activities. Regulatory authorities have extensive discretion in their supervisory and enforcement activities, including the imposition of restrictions on our operations, the classification of our assets and determination of the level of our allowance for loan losses. Banking regulations, designed primarily for the protection of depositors, may limit our growth and the return to our shareholders by restricting certain of our activities, such as: • • • • • • • • the payment of dividends to our shareholders, possible mergers with or acquisitions of or by other institutions, desired investments, loans and interest rates on loans, interest rates paid on deposits, service charges on deposit account transactions, the possible expansion of branch offices, and the ability to provide securities or trust services. We also are subject to regulatory capital requirements. We could be subject to regulatory enforcement actions if, any of our regulators determines for example, that we have violated a law of regulation, engaged in unsafe or unsound banking practice or lack adequate capital. Federal and state governments and regulators could pass legislation and adopt policies responsive to current credit conditions that would have an adverse effect on the Company and its financial performance. We cannot predict what changes, if any, will be made to existing federal and state legislation and regulations or the effect that such changes may have on our future business and earnings prospects. Any change in such regulation and oversight, whether in the form of regulatory policy, regulations, legislation or supervisory action, may have a material adverse impact on our operations. Compliance with changing regulation of corporate governance and public disclosure may result in additional risks and expenses. Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Dodd-Frank Act, the Sarbanes-Oxley Act of 2002 and new SEC regulations, are creating additional expense for publicly-traded companies such as the Company. The application of these laws, regulations and standards may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, our efforts to comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, increased expenses and a diversion of management time and attention. In particular, our efforts to comply with Section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations regarding management’s required assessment of its internal control over financial reporting and its external auditors’ audit of our internal control over financial reporting requires, and will continue to require, the commitment of significant financial and managerial resources. Further, the members of our board of directors, members of our audit or compensation and management succession committees, our chief executive officer, our chief financial officer and certain other executive officers could face an increased risk of personal liability in connection with the performance of their duties. It may also become more difficult and more expensive to obtain director and officer liability insurance. As a result, our ability to attract and retain executive officers and qualified board and committee members could be more difficult. We may be adversely affected by recent changes in U.S. tax laws. The enactment of the Tax Cuts and Jobs Act (the “TCJA”) on December 22, 2017 made significant changes to the Internal Revenue Code, many of which are highly complex and may require interpretations and implementing regulations. As a result of the TCJA’s reduction of the corporate income tax rate from 35% to 21%, we were required to re-measure our net deferred tax assets and to record a charge to income tax expense in the quarter ended December 31, 2017 of approximately $7.4 million, which amount is subject to refinement in future periods as further information becomes available. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Income Taxes”. Furthermore, we may incur additional meaningful expenses (including professional fees) as the TCJA is implemented, and the expected impact of certain aspects of the statute remains unclear and subject to change. The TCJA includes a number of provisions that will have an impact on the banking industry, borrowers and the market for residential real estate. These changes include: (i) a lower limit on the deductibility of mortgage interest on single-family residential mortgage loans, (ii) the elimination of interest deductions for home equity loans, (iii) a limitation on the deductibility of business interest expense, and (iv) a limitation on the deductibility of property taxes and state and local 14 income taxes. The TCJA may have an adverse effect on the market for and the valuation of residential properties, as well as on the demand for such loans in the future, and could make it harder for borrowers to make their loan payments. The value of the properties securing loans in our loan portfolio may be adversely impacted as a result of the changing economics of home ownership. Such an impact could require an increase in our provision for loan losses, which would reduce our profitability and could materially adversely affect our business, financial condition and results of operations. Risks Related to Growth and Expansion Goodwill resulting from acquisitions may adversely affect our results of operations. Goodwill and other intangible assets have increased substantially as a result of our acquisition of North Valley Bancorp in 2014 and will further increase following our acquisition of FNBB. Potential impairment of goodwill and amortization of other intangible assets could adversely affect our financial condition and results of operations. We assess our goodwill and other intangible assets and long- lived assets for impairment annually and more frequently when required by U.S. GAAP. We are required to record an impairment charge if circumstances indicate that the asset carrying values exceed their fair values. Our assessment of goodwill, other intangible assets, or long-lived assets could indicate that an impairment of the carrying value of such assets may have occurred that could result in a material, non-cash write-down of such assets, which could have a material adverse effect on our results of operations and future earnings. If we cannot attract deposits, our growth may be inhibited. We plan to increase the level of our assets, including our loan portfolio. Our ability to increase our assets depends in large part on our ability to attract additional deposits at favorable rates. We intend to seek additional deposits by offering deposit products that are competitive with those offered by other financial institutions in our markets and by establishing personal relationships with our customers. We cannot assure that these efforts will be successful. Our inability to attract additional deposits at competitive rates could have a material adverse effect on our business, financial condition, results of operations and cash flows. Existing and potential acquisitions may disrupt our business and dilute stockholder value. On December 11, 2017, we entered into the Merger Agreement providing for our acquisition of FNBB and its wholly-owned subsidiary, First National Bank of Northern California. The Merger is expected to close in the second quarter of 2018, subject to the satisfaction of customary closing conditions, including the receipt of regulatory and shareholder approvals. The success of the merger will depend on, among other things, our ability to realize the anticipated revenue enhancements and efficiencies and to combine the businesses of the Company and FNBB in a manner that does not materially disrupt the existing customer relationships of FNBB or result in decreased revenues resulting from any loss of customers and that permits growth opportunities to occur. If we are not able to successfully achieve these objectives, the anticipated benefits of the Merger may not be realized fully or at all or may take longer to realize than expected. The Company and FNBB have operated and, until the completion of the Merger, will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of the Merger. Integration efforts between the two companies could also divert management attention and resources. These integration matters could have an adverse effect on each of the Company and FNBB the transition period and on the combined company following completion of the Merger. We intend to continue to explore expanding our branch system through opening new bank branches and in-store branches in existing or new markets in northern and central California. In the ordinary course of business, we evaluate potential branch locations that would bolster our ability to cater to the small business, individual and residential lending markets in California. Any given new branch, if and when opened, will have expenses in excess of revenues for varying periods after opening that may adversely affect our results of operations or overall financial condition. As a result, merger or acquisition discussions and, in some cases, negotiations may take place and future mergers or acquisitions involving cash, debt or equity 15 securities may occur at any time. Acquisitions typically involve the payment of a premium over book and market values, and, therefore, some dilution of our stock’s tangible book value and net income per common share may occur in connection with any future transaction. Furthermore, failure to realize the expected revenue increases, cost savings, increases in geographic or product presence, and/or other projected benefits from recent or future acquisitions could have a material adverse effect on our financial condition and results of operations. We cannot say with any certainty that we will be able to consummate, or if consummated, successfully integrate future acquisitions or that we will not incur disruptions or unexpected expenses in integrating such acquisitions. In attempting to make such future acquisitions, we anticipate competing with other financial institutions, many of which have greater financial and operational resources. Acquiring other banks, businesses, or branches involves various risks commonly associated with acquisitions, including, among other things: • • • • • • • incurring substantial expenses in pursuing potential acquisitions without completing such acquisitions, exposure to potential asset quality issues of the target company, losing key clients as a result of the change of ownership, the acquired business not performing in accordance with our expectations, difficulties and expenses arising in connection with the integration of the operations of the acquired business with our operations, difficulty in estimating the value of the target company, needing to make significant investments and infrastructure, controls, staff, emergency backup facilities or other critical business functions that become strained by our growth, • management needing to divert attention from other aspects of our business, • • • • • • potentially losing key employees of the acquired business, incurring unanticipated costs which could reduce our earnings per share, assuming potential liabilities of the acquired company as a result of the acquisition, potential changes in banking or tax laws or regulations that may affect the target company, potential disruption to our business, and an acquisition may dilute our earnings per share, in both the short and long term, or it may reduce our tangible capital ratios. Our growth and expansion may strain our ability to manage our operations and our financial resources. Our financial performance and profitability depend on our ability to execute our corporate growth strategy. In addition to seeking deposit and loan and lease growth in our existing markets, we may pursue expansion opportunities in new markets. Continued growth, however, may present operating and other problems that could adversely affect our business, financial condition, results of operations and cash flows. Accordingly, there can be no assurance that we will be able to execute our growth strategy or maintain the level of profitability that we have recently experienced. Our growth may place a strain on our administrative, operational and financial resources and increase demands on our systems and controls. This business growth may require continued enhancements to and expansion of our operating and financial systems and controls and may strain or significantly challenge them. In addition, our existing operating and financial control systems and infrastructure may not be adequate to maintain and effectively monitor future growth. Our continued growth may also increase our need for qualified personnel. We cannot assure you that we will be successful in attracting, integrating and retaining such personnel. Risks Relating to Dividends and Our Common Stock Our future ability to pay dividends is subject to restrictions. As a holding company with no significant assets other than the Bank, we depend on dividends from the Bank to fund our operations and for a substantial portion of our revenues. Our ability to continue to pay dividends depends in large part upon our receipt of dividends or other capital distributions from the Bank. The ability of the Bank to pay dividends or make other capital distributions to us is subject to the restrictions in the California Financial Code. As of December 31, 2017, the Bank could have paid approximately $85,254,000 in dividends to TriCo without the prior approval of the DBO. The amount that the Bank may pay in dividends is further restricted due to the fact that the Bank must maintain a certain minimum amount of capital to be considered a “well capitalized” institution as well as a separate capital conservation buffer, as further described under “Item 1 – Supervision and Regulation — Regulatory Capital Requirements” in this report. 16 From time to time, we may become a party to financing agreements or other contractual arrangements that have the effect of limiting or prohibiting us or the Bank from declaring or paying dividends. Our holding company expenses and obligations with respect to our trust preferred securities and corresponding junior subordinated deferrable interest debentures issued by us may limit or impair our ability to declare or pay dividends. Finally, our ability to pay dividends is also subject to the restrictions of the California Corporations Code. See “Regulation and Supervision – Restrictions on Dividends and Distributions.” Anti-takeover provisions and federal law may limit the ability of another party to acquire us, which could cause our stock price to decline. Various provisions of our articles of incorporation and bylaws could delay or prevent a third party from acquiring us, even if doing so might be beneficial to our shareholders. These provisions provide for, among other things, specified actions that the Board of Directors shall or may take when an offer to merge, an offer to acquire all assets or a tender offer is received and the authority to issue preferred stock by action of the board of directors acting alone, without obtaining shareholder approval. The BHC Act and the Change in Bank Control Act of 1978, as amended, together with federal regulations, require that, depending on the particular circumstances, either FRB approval must be obtained or notice must be furnished to the FRB and not disapproved prior to any person or entity acquiring “control” of a bank holding company such as TriCo. These provisions may prevent a merger or acquisition that would be attractive to shareholders and could limit the price investors would be willing to pay in the future for our common stock. The amount of common stock owned by, and other compensation arrangements with, our officers and directors may make it more difficult to obtain shareholder approval of potential takeovers that they oppose. As of December 31, 2017, directors and executive officers beneficially owned approximately 8.9% of our common stock and our Employee Stock Ownership Plan (“ESOP”) owned approximately 5.1%. Agreements with our senior management also provide for significant payments under certain circumstances following a change in control. These compensation arrangements, together with the common stock beneficially owned by our board of directors, management, and the ESOP could make it difficult or expensive to obtain majority support for shareholder proposals or potential acquisition proposals of us that our directors and officers oppose. We may issue additional common stock or other equity securities in the future which could dilute the ownership interest of existing shareholders. In order to maintain our capital at desired or regulatory-required levels, or to fund future growth, our board of directors may decide from time to time to issue additional shares of common stock, or securities convertible into, exchangeable for or representing rights to acquire shares of our common stock. The sale of these shares may significantly dilute your ownership interest as a shareholder. New investors in the future may also have rights, preferences and privileges senior to our current shareholders which may adversely impact our current shareholders. Holders of our junior subordinated debentures have rights that are senior to those of our common stockholders. We have supported our continued growth through the issuance of trust preferred securities from special purpose trusts and accompanying junior subordinated debentures. At December 31, 2017, we had outstanding trust preferred securities and accompanying junior subordinated debentures with face value of $62,889,000. Payments of the principal and interest on the trust preferred securities are conditionally guaranteed by us. Further, the accompanying junior subordinated debentures we issued to the trusts are senior to our shares of common stock. As a result, we must make payments on the junior subordinated debentures before we can pay any dividends on our common stock and, in the event of our bankruptcy, dissolution or liquidation, the holders of the junior subordinated debentures must be satisfied before any distributions can be made on our common stock. Risks Relating to Systems, Accounting and Internal Controls If we fail to maintain an effective system of internal and disclosure controls, we may not be able to accurately report our financial results or prevent fraud. As a result, current and potential shareholders could lose confidence in our financial reporting, which would harm our business and the trading price of our securities. Effective internal control over financial reporting and disclosure controls and procedures are necessary for us to provide reliable financial reports and effectively prevent fraud and to operate successfully as a public company. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results would be harmed. We continually review and analyze our internal control over financial reporting for Sarbanes-Oxley Section 404 compliance. As part of that process we may discover material weaknesses or significant deficiencies in our internal control as defined under standards adopted by the Public Company Accounting Oversight Board that require remediation. A material weakness is a deficiency, or combination 17 of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected in a timely basis. A significant deficiency is a deficiency or combination of deficiencies, in internal control over financial reporting that is less severe than material weakness, yet important enough to merit attention by those responsible for the oversight of the Company’s financial reporting. As a result of weaknesses that may be identified in our internal controls, we may also identify certain deficiencies in some of our disclosure controls and procedures that we believe require remediation. If we discover weaknesses, we will make efforts to improve our internal and disclosure controls. However, there is no assurance that we will be successful. Any failure to maintain effective controls or timely effect any necessary improvement of our internal and disclosure controls could harm operating results or cause us to fail to meet our reporting obligations, which could affect our ability to remain listed with Nasdaq. Ineffective internal and disclosure controls could also cause investors to lose confidence in our reported financial information, which would likely have a negative effect on the trading price of our securities. We rely on communications, information, operating and financial control systems technology and we may suffer an interruption in or breach of the security of those systems. We rely heavily on our communications, information, operating and financial control systems technology to conduct our business. We rely on third party services providers to provide many of these systems. Any failure, interruption or breach in security of these systems could result in failures or interruptions in our customer relationship management, general ledger, deposit, servicing and loan origination systems. We cannot assure you that such failures, interruptions or security breaches will not occur or, if they do occur, that they will be adequately addressed by us or the third parties service providers on which we rely. The occurrence of any failures, interruptions or security breaches could damage our reputation, result in a loss of customers, expose us to possible financial liability, lead to additional regulatory scrutiny or require that we make expenditures for remediation or prevention. Any of these circumstances could have a material adverse effect on our business, financial condition, results of operations and cash flows. 18 We rely on certain third-party vendors. We are reliant upon certain third-party vendors to provide products and services necessary to maintain our day-to-day operations. Accordingly, our operations are exposed to risk that these vendors will not perform in accordance with applicable contractual arrangements or service level agreements. We maintain a system of policies and procedures designed to monitor vendor risks including, among other things, (i) changes in the vendor’s organizational structure, (ii) changes in the vendor’s financial condition, (iii) changes in existing products and services or the introduction of new products and services, and (iv) changes in the vendor’s support for existing products and services. While we believe these policies and procedures help to mitigate risk, the failure of an external vendor to perform in accordance with applicable contractual arrangements or the service level agreements could be disruptive to our operations, which could have a material adverse effect on our business and our financial condition and results of operations. Our business is highly reliant on technology and our ability and our third party service providers to manage the operational risks associated with technology. Our business involves storing and processing sensitive consumer and business customer data. We depend on internal systems, third party service providers, and outsourced technology to support these data storage and processing operations. Despite our efforts to ensure the security and integrity of our systems, we may not be able to anticipate, detect or recognize threats to our systems or those of third party service providers or to implement effective preventive measures against all cyber security breaches. Cyberattack techniques change regularly and can originate from a wide variety of sources, including third parties who are or may be involved in organized crime or linked to terrorist organizations or hostile foreign governments, and such third parties may seek to gain access to systems directly or using equipment or security passwords belonging to employees, customers, third-party service providers or other users of our systems. These risks may increase in the future as we continue to increase our mobile and other internet-based product offerings and expands our internal usage of web-based products and applications. A cyber security breach or cyberattack could persist for a long time before being detected and could result in theft of sensitive data or disruption of our transaction processing systems. Our inability to use or access these information systems at critical points in time could unfavorably impact the timeliness and efficiency of our business operations. A material breach of customer data security may negatively impact our business reputation and cause a loss of customers, result in increased expense to contain the event and/or require that we provide credit monitoring services for affected customers, result in regulatory fines and sanctions and/or result in litigation. Cyber security risk management programs are expensive to maintain and will not protect us from all risks associated with maintaining the security of customer data and our proprietary data from external and internal intrusions, disaster recovery and failures in the controls used by our vendors. In addition, Congress and the legislatures of states in which we operate regularly consider legislation that would impose more stringent data privacy requirements, resulting in increased compliance costs. A failure to implement technological advances could negatively impact our business. The banking industry is undergoing technological changes with frequent introductions of new technology-driven products and services. In addition to improving customer services, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, on our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources than we do to invest in technological improvements. We may not be able to effectively implement new technology-driven products and services or successfully market such products and services to our customers. ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES The Company is engaged in the banking business through 57 traditional branches, 9 in-store branches and 2 loan production offices in 26 counties in northern and central California including twelve offices in Shasta County, eight in Butte County, six in Humboldt County, five in Nevada County, four in Sacramento and Stanislaus Counties, three in Placer and Siskiyou Counties, two each in Fresno, Glenn, Mendocino, Sutter and Trinity Counties, and one each in Colusa, Contra Costa, Del Norte, Kern, Lake, Lassen, Madera, Merced, Sonoma, Tehama, Tulare, Yolo and Yuba Counties. All offices are constructed and equipped to meet prescribed security requirements. The Company owns twenty-nine branch office locations, one administrative building with a branch location, five administrative buildings, and one other building that it leases out. The Company leases thirty-six branch office locations, two loan production offices, and three administrative locations. Most of the leases contain multiple renewal options and provisions for rental increases, principally for changes in the cost of living index, property taxes and maintenance. 19 ITEM 3. LEGAL PROCEEDINGS On September 15, 2014, a former Personal Banker at one of the Bank’s in-store branches filed a Class Action Complaint against the Bank in Butte County Superior Court, alleging causes of action related to the observance of meal and rest periods and seeking to represent a class of current and former branch employees with the same or similar job duties, employed by the Bank within the State of California during the preceding four years. On or about June 25, 2015, Plaintiff filed an Amended Complaint expanding the class definition to include all current and former non-exempt branch employees employed by the Bank within the State of California at any time during the period of September 15, 2010 to the entry of judgment. The Bank responded to the First Amended Complaint by denying the charges and the parties engaged in written discovery. The parties then engaged in non-binding mediation during the third quarter of 2016. In addition to this, on January 20, 2015, a then-current Personal Banker at one of the Bank’s in-store branches filed a First Amended Complaint against the Bank and the Company in Sacramento County Superior Court, alleging causes of action related to wage statement violations. As part of the Complaint Plaintiff is seeking to represent a class of current and former exempt and non-exempt employees who worked for the Company and/or the Bank during the time period of December 12, 2013 to the date of filing the action. The Company and the Bank responded to the First Amended Complaint by denying the charges and engaging in written discovery with Plaintiff. The parties then engaged in non-binding mediation of the action during the third quarter of 2016 as well. This matter was transferred to the Butte County Superior Court and consolidated with the case above, effective August 25, 2017. As part of the mediations, which took place concurrently, the Bank agreed in principal to settle the two matters in a consolidated settlement proceeding. The agreement was preliminarily approved by the court and notices were sent to the members of the purported classes. After reviewing the received claims, on January 12, 2018, the court approved the final settlement agreement on both matters. The total cost to the Bank was $1,469,000, of which $1,450,000 was previously accrued as of December 31, 2017 and 2016. These matters will not be discussed in future filings. Neither the Company nor its subsidiaries are a party to any other pending legal proceedings that are material, nor is their property the subject of any other material pending legal proceeding at this time. All other legal proceedings are routine and arise out of the ordinary course of the Bank’s business. None of those proceedings are currently expected to have a material adverse impact upon the Company’s and the Bank’s business, their consolidated financial position nor their operations in any material amount not already accrued, after taking into consideration any applicable insurance.

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Common Stock Market Prices and Dividends The Company’s common stock is traded on the Nasdaq under the symbol “TCBK.” The following table shows the high and the low closing sale prices for the common stock for each quarter in the past two years, as reported by Nasdaq: 2017: Fourth quarter Third quarter Second quarter First quarter 2016: Fourth quarter Third quarter Second quarter First quarter High $43.42 $40.75 $36.77 $37.38 $34.46 $28.40 $28.90 $27.44 Low $37.86 $33.60 $33.05 $32.84 $25.49 $25.40 $24.60 $23.80 As of February 23, 2018 there were approximately 1,583 shareholders of record of the Company’s common stock. On February 23, 2018, the closing sales price was $38.29. The Company has paid cash dividends on its common stock in every quarter since March 1990, and it is currently the intention of the Board of Directors of the Company to continue payment of cash dividends on a quarterly basis. There is no assurance, however, that any dividends will be paid since they are dependent upon earnings, financial condition and capital requirements of the Company and the Bank. As of December 31, 2017 $85,254,000 was available for payment of dividends by the Bank to the Company, under applicable laws and regulations. The Company paid cash dividends of $0.17 per common share in each of the quarters ended December 31, 2017, September 30, 2017, June 30, 2017, and $0.15 per common share in each of the quarters ended March 31, 2017, December 31, 2016, September 30, 2016, June 30, 2016, March 31, 2016. Issuer Repurchases of Common Stock The Company adopted a stock repurchase plan on August 21, 2007 for the repurchase of up to 500,000 shares of the Company’s common stock from time to time as market conditions allow. The 500,000 shares authorized for repurchase under this plan represented approximately 3.2% of the Company’s approximately 15,815,000 common shares outstanding as of August 21, 2007. This plan has no stated expiration date for the repurchases. As of December 31, 2017, the Company had purchased 166,600 shares under this plan. The following table shows the repurchases made by the Company or any affiliated purchaser (as defined in Rule 10b-18(a)(3) under the Exchange Act) during the fourth quarter of 2017: Period Oct. 1-31, 2017 Nov. 1-30, 2017 Dec. 1-31, 2017 Total (a) Total number of shares purchased(1) — — — — (b) Average price paid per share — — — — (c) Total number of shares purchased as of part of publicly announced plans or programs — — — — (d) Maximum number shares that may yet be purchased under the plans or programs(2) 333,400 333,400 333,400 333,400 (1) Includes shares purchased by the Company’s Employee Stock Ownership Plan and pursuant to various other equity incentive plans.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS General As TriCo Bancshares has not commenced any business operations independent of the Bank, the following discussion pertains primarily to the Bank. Average balances, including such balances used in calculating certain financial ratios, are generally comprised of average daily balances for the Company. Within Management’s Discussion and Analysis of Financial Condition and Results of Operations, interest income and net interest income are generally presented on a fully tax-equivalent (FTE) basis. The presentation of interest income and net interest income on a FTE basis is a common practice within the banking industry. Interest income and net interest income are shown on a non-FTE basis in this Item 7 this report, and a reconciliation of the FTE and non-FTE presentations is provided below in the discussion of net interest income. Critical Accounting Policies and Estimates The Company’s discussion and analysis of its financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP). The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those that materially affect the financial statements and are related to the adequacy of the allowance for loan losses, investments, mortgage servicing rights, fair value measurements, retirement plans, intangible assets and the fair value of acquired assets and liabilities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The Company’s policies related to estimates on the allowance for loan losses, other than temporary impairment of investments and impairment of intangible assets, can be found in Note 1 in the financial statements at Item 8 of this report. Average balances, including balances used in calculating certain financial ratios, are generally comprised of average daily balances for the Company. Within Management’s Discussion and Analysis of Financial Condition and Results of Operations, certain performance measures including interest income, net interest income, net interest yield, and efficiency ratio are generally presented on a fully tax-equivalent (FTE) basis. The Company believes the use of these non-generally accepted accounting principles (non-GAAP) measures provides additional clarity in assessing its results. On March 18, 2016, the Bank completed its acquisition of three branch banking offices from Bank of America originally announced October 28, 2015. The acquired branches are located in Arcata, Eureka and Fortuna in Humboldt County on the North Coast of California, and have significant overlap compared to the Company’s then-existing Northern California customer base and branch locations. As a result, these branch acquisitions create potential cost savings and future growth potential. With the levels of capital at the time, the acquisitions fit well into the Company’s growth strategy. Also on March 18, 2016, the electronic customer service and other data processing systems of the acquired branches were converted into the Bank’s systems, and the effect of revenue and expenses from the operations of the acquired branches are included in the results of the Company. The Bank paid a premium of $3,204,000 for deposit relationships with balances of $161,231,000 and loans with balances of $289,000, and received cash of $159,520,000 from Bank of America. The Company refers to loans and foreclosed assets that are covered by loss sharing agreements as “covered loans” and “covered foreclosed assets”, respectively. In addition, the Company refers to loans purchased or obtained in a business combination as “purchased credit impaired” (PCI) loans, or “purchased not credit impaired” (PNCI) loans. The Company refers to loans that it originates as “originated” loans. Additional information regarding the North Valley Bancorp acquisition can be found in Note 2 in the financial statements at Item 8 of this report. Additional information regarding the definitions and accounting for originated, PNCI and PCI loans can be found in Notes 1, 2, 4 and 5 in the financial statements at Item 8 of this report, and under the heading Asset Quality and Non-Performing Assets below. Geographical Descriptions For the purpose of describing the geographical location of the Company’s loans, the Company has defined northern California as that area of California north of, and including, Stockton; central California as that area of the State south of Stockton, to and including, Bakersfield; and southern California as that area of the State south of Bakersfield. 24 Results of Operations Overview The following discussion and analysis is designed to provide a better understanding of the significant changes and trends related to the Company and the Bank’s financial condition, operating results, asset and liability management, liquidity and capital resources and should be read in conjunction with the consolidated financial statements of the Company and the related notes at Item 8 of this report. Following is a summary of the components of net income for the periods indicated (dollars in thousands): Net interest income (Provision for) benefit from reversal of provision for loan losses Noninterest income Noninterest expense Taxes Net income Net income per average fully-diluted share Net income as a percentage of average shareholders’ equity (ROAE) Net income as a percentage of average total assets (ROAA) 2017 $ 174,604 Year ended December 31, 2016 $ 167,987 2015 $ 155,998 (89) 50,021 (147,024) (36,958) $ 40,554 1.77 $ 5,970 44,563 (145,997) (27,712) $ 44,811 1.94 $ 2,210 45,347 (130,841) (28,896) $ 43,818 1.91 $ 8.10% 0.89% 9.46% 1.02% 10.04% 1.11% The Company uses certain non-GAAP measures to provide supplemental information regarding performance. The Company believes that presenting net income, effective tax rate, return on average assets (ROAA), return on average equity (ROAE), and earnings per common share, excluding the impact of merger & acquisition expenses and the effect of changes in tax rates, provides additional clarity to the users of the financial statements regarding core financial performance. The following table presents a comparison of net income, effective tax rate, ROAA, ROAE, and earnings per common share as reported, and as adjusted for the impact of merger & acquisition expenses and changes in tax rates, for the periods indicated: (amounts in thousands, except per share amounts) Net income Effect of merger & acquisition expenses Effect of income tax rate change Adjusted net income Income tax expense Effect of non-deductible merger & acquisition expenses Effect of income tax rate change Adjusted income tax expense Effective tax rate Adjusted effective tax rate ROAA Adjusted ROAA ROAE Adjusted ROAE Earnings per common share: Basic Diluted Adjusted earnings per common share: Basic Diluted Merger & acquisition expenses Non-deductible merger & acquisition expenses Average assets Average equity Weighted average shares Weighted average diluted shares $ $ $ $ $ $ 2017 40,554 491 7,416 48,462 36,958 (184) (7,416) 29,358 $ Year ended December 31, 2016 44,811 454 — 45,266 27,712 — — 27,712 $ $ $ 47.7% 37.9% 0.89% 1.06% 8.10% 9.68% 1.77 1.74 38.2% 38.2% 1.02% 1.04% 9.46% 9.55% $ $ 1.96 1.94 $ $ $ 1.98 1.96 784 — $4,373,022 $ 473,829 22,814 23,086 2.12 $ 2.08 $ 530 $ $ 438 $4,554,505 $ 500,653 22,912 23,250 25 2015 43,818 340 — 44,158 28,896 — — 28,896 39.7% 39.7% 1.11% 1.11% 10.04% 10.12% 1.93 1.91 $ $ $ $ $ $ $ $ $ 1.94 1.92 586 — $3,963,998 $ 436,301 22,750 22,998 Net Interest Income The Company’s primary source of revenue is net interest income, which is the difference between interest income on earning assets and interest expense on interest-bearing liabilities. Following is a summary of the Company’s net interest income for the periods indicated (dollars in thousands): Components of Net Interest Income Interest income Interest expense Net interest income FTE adjustment Net interest income (FTE) Net interest margin (FTE) Year ended December 31, 2016 2015 2017 $181,402 (6,798) 174,604 2,499 $177,103 $173,708 (5,721) 167,987 2,329 $170,316 $161,414 (5,416) 155,998 905 $156,903 4.22% 4.23% 4.32% Net interest income (FTE) for the year ended December 31, 2017 increased $6,787,000 (4.0%) to $177,103,000 from $170,316,000 during the year ended December 31, 2016. The increase in net interest income (FTE) was due primarily to a $212,930,000 (8.1%) increase in the average balance of loans to $2,842,659,000, and a 9 basis point increase in the average yield on investments–taxable that were partially offset by a 21 basis point decrease in the average yield on loans, and a 3 basis point increase in the average rate paid on interest bearing liabilities. The $212,930,000 increase in average loan balances compared to the prior year was due primarily to net organic (i.e., not purchased) loan growth that was funded by deposit growth and the use of interest bearing cash at banks and other borrowings. The 9 basis point increase in the average yield on investments-taxable was due to increased market rates on investment purchased, and slower prepay speeds on the Company’s mortgage backed securities (“MBS”) investments in 2017 compared to 2016. Slower prepay speeds for MBS investments with net purchase premiums result in higher yields, as was the case for the Company’s MBS investments during 2017 compared to 2016. Accounting for 12 basis points of the 21 point decrease in the average yield on loans from 2016 to 2017 was the recovery of $2,311,000 of loan interest income from the sale of loans in 2016. A decrease in purchased loan discounts accretion accounted for 5 basis points of the 21 point decrease in average loan yield, and the remaining 4 basis point decrease in average loan yield was due primarily to lower average yields on new loans compared to existing loans, primarily during the first half of 2017 that was somewhat alleviated in the second half of 2017 and included the effects of 25 basis point increases in the Federal Funds Rate and the Prime Lending Rate during each of December 2016, and March, June, and December 2017. The 3 basis point increase in the average rate paid on interest-bearing liabilities was due primarily to increased rates paid on time deposits, other borrowings, and junior subordinated debt. Net interest income (FTE) for the year ended December 31, 2016 increased $13,413,000 (8.6%) to $170,316,000 from $156,903,000 during the year ended December 31, 2015. The increase in net interest income (FTE) was due primarily to a $240,292,000 (10.1%) increase in the average balance of loans to $2,629,729,000, a $140,526,000 (13.4%) increase in the average balance of investments to $1,190,509,000, and a seven basis point increase in the average yield of nontaxable investments from 4.85% during the year ended December 31, 2015 to 4.92% during the year ended December 31, 2016 , that were partially offset by a 15 basis point decrease in the average yield on loans from 5.52% during the year ended December 31, 2015 to 5.37% during the year ended December 31, 2016, and a 15 basis point decrease in the average yield on investments taxable from 2.74% during the year ended December 31, 2015 to 2.59% during the year ended December 31, 2016. The $240,292,000 increase in average loan balances during 2016 compared to 2015 was due primarily to organic loan growth. The $140,526,000 increase in average investment balances during 2016 compared to 2015 was due primarily to investment purchases in excess of investment maturities. The increases in average loan and investment balances during 2016 were funded primarily by a $350,461,000 increase in the average balance of deposits, and a $37,528,000 increase in the average balance of shareholders’ equity during 2016. The $350,461,000 increase in the average balance of deposits during 2016 compared to 2015 included the effect of the purchase of three branches and $161,231,000 of deposits from Bank of America on March 18, 2016. The seven basis point increase in the average yield of investments nontaxable was due to purchases of investments nontaxable with higher average tax-equivalent yields during 2016 compared to the yields on investments nontaxable that the Company owned during 2015. The 15 basis point decrease in average loan yields was due primarily to declines in market yields on new and renewed loans compared to yields on repricing, maturing, and paid off loans. The 15 basis point decrease in the average yield of investments taxable was due to purchases of investments taxable with lower average tax-equivalent yields during 2016 compared to the yields on investments taxable that the Company owned during 2015, and increased amortization of purchase premiums on mortgage backed securities during 2016 compared to 2015. The increased amortization of purchase premiums on mortgage backed securities during 2016 was due primarily to faster prepayment of existing mortgages caused by higher mortgage refinance activity that was caused by reduced mortgage rates during most of 2016 compared to 2015. The increases in average loan and investment balances added $13,264,000 and $5,461,000, respectively, to net interest income (FTE) while the decreases in average loan and investments taxable yields reduced net interest income (FTE) during 2016 by $4,104,000 and $1,602,000, respectively, compared to 2015. The increase in average investments nontaxable yield increased net interest income (FTE) during 2016 by $94,000 compared to 2015. Included in investment interest income during the years ended December 31, 2016 and 2015 were special cash dividend of $578,000 and $626,000, respectively, from the Company’s investment in Federal Home Loan Bank of San Francisco stock. 26 Included in loan interest income during the year ended December 31, 2016 was discount accretion from purchased loans of $7,399,000 compared to $10,056,000 during the year ended December 31, 2015. Also included in loan interest income during the year ended December 31, 2016 was interest income of $2,311,000 from the recovery of interest payments previously applied to principal balances of nonperforming loans sold during 2016. Included in loan interest income during the year ended December 31, 2015 was the recovery of $728,000 of loan interest income from the payoff of a single originated loan that was in interest nonaccrual status; and while recoveries of loan interest income from paid off nonaccrual loans occur from time to time, a single recovery of this magnitude is unusual. For more information related to loan interest income, including loan purchase discount accretion, see the Summary of Average Balances, Yields/Rates and Interest Differential and Note 30 to the consolidated financial statements at Part II, Item 8 of this report. The “Yield” and “Volume/Rate” tables shown below are useful in illustrating and quantifying the developments that affected net interest income during 2017 and 2016. Summary of Average Balances, Yields/Rates and Interest Differential – Yield Tables The following tables present, for the periods indicated, information regarding the Company’s consolidated average assets, liabilities and shareholders’ equity, the amounts of interest income from average earning assets and resulting yields, and the amount of interest expense paid on interest-bearing liabilities. Average loan balances include nonperforming loans. Interest income includes proceeds from loans on nonaccrual loans only to the extent cash payments have been received and applied to interest income. Yields on securities and certain loans have been adjusted upward to reflect the effect of income thereon exempt from federal income taxation at the current statutory tax rate (dollars in thousands): Assets Loans Investment securities - taxable Investment securities - nontaxable Cash at Federal Reserve and other banks Total earning assets Other assets Total assets Liabilities and shareholders’ equity Interest-bearing demand deposits Savings deposits Time deposits Other borrowings Junior subordinated debt Total interest-bearing liabilities Noninterest-bearing demand Other liabilities Shareholders’ equity Total liabilities and shareholders’ equity Net interest spread (1) Net interest income and interest margin (2) Year ended December 31, 2017 Interest income/expense Rates earned/paid Average balance $2,842,659 1,087,302 136,240 126,432 4,192,633 361,872 $4,554,505 $ 939,516 1,368,705 317,724 41,252 56,762 2,723,959 1,262,592 67,301 500,653 $4,554,505 $ 146,794 29,096 6,664 1,347 183,901 744 1,683 1,531 305 2,535 6,798 5.16% 2.68% 4.89% 1.07% 4.39% 0.08% 0.12% 0.48% 0.74% 4.47% 0.25% $ 177,103 4.14% 4.22% (1) Net interest spread represents the average yield earned on interest-earning assets less the average rate paid on interest-bearing liabilities.

The rate/volume variance has been included in the rate variance. Amounts are calculated on a fully taxable equivalent basis: 2017 over 2016 Yield/ Rate Volume 2016 over 2015 Yield/ Rate Total Total Volume (dollars in thousands) Increase (decrease) in interest income: Loans Investments - taxable Investments - nontaxable Cash at Federal Reserve and other banks Total Increase (decrease) in interest expense: Demand deposits (interest-bearing) Savings deposits Time deposits Other borrowings Junior subordinated debt Total $11,434 593 499 (449) 12,077 $(5,726) $5,708 1,518 454 184 (4,213) 7,864 925 (45) 633 $13,264 $(4,014) $ 9,250 157 (1,602) 3,796 515 (5,061) 13,718 1,759 3,702 54 18,779 94 461 31 32 (99) 11 8 (17) 303 (2) 272 (34) 273 285 298 1,094 174 296 306 1,077 $(5,307) $6,787 42 193 9 5 8 257 (35) 210 (126) 5 251 305 $18,522 $(5,109) $13,413 (77) 17 (135) — 243 48 Increase (decrease) in net interest income $12,094 Provision for Loan Losses The provision for loan losses during any period is the sum of the allowance for loan losses required at the end of the period and any loan charge offs during the period, less the allowance for loan losses required at the beginning of the period, and less any loan recoveries during the period. See the Tables labeled “Allowance for loan losses – year ended December 31, 2017 and 2016” at Note 5 in Item 8 of Part II of this report for the components that make up the provision for loan losses for the years ended December 31, 2017 and 2016. The Company provided $89,000 for loan losses during the year ended December 31, 2017 versus a $5,970,000 reversal of provision for loan losses during the year ended December 31, 2016. The increase in provision for loan losses for the year ended December 31, 2017 compared to the year ended December 31, 2016 was due primarily to an increase of $4,266,000 (21.2%) in nonperforming loans during 2017 compared to a $16,991,000 (45.8%) decrease in nonperforming loans during 2016, and net charge-offs of $2,269,000 during 2017 compared to net recoveries of $2,462,000 during 2016. As shown in the Table labeled “Allowance for Loan Losses - year ended December 31, 2017” at Note 5 in Item 8 of Part II of this report residential and commercial real estate loans, home equity lines of credit, home equity loans, and commercial construction loans experienced a reversal of provision for loan losses during the year ended December 31, 2017. The level of provision, or reversal of provision, for loan losses of each loan category during the year ended December 31, 2017 was due primarily to a decrease in the required allowance for loan losses as of December 31, 2017 when compared to the required allowance for loan losses as of December 31, 2016 less net charge-offs during the year ended December 31, 2017. All categories of loans except C & I loans experienced a decrease in the required allowance for loan losses during the year ended December 31, 2017. These decreases in required allowance for loan losses were due primarily to improvements in estimated cash flows and collateral values for impaired loans, and reductions in historical loss factors that were offset by increases in loan balances and nonperforming loans in some loan categories. For details of the change in nonperforming loans during the year ended December 31, 2017 see the Tables, and associated narratives, labeled “Changes in nonperforming assets during the year ended December 31, 2017” and “Changes in nonperforming assets during the three months ended December 31, September 30, June 30, and March 31, 2017” under the heading “Asset Quality and Non-Performing Assets” below. The Company benefited from a $5,970,000 reversal of provision for loan losses during the year ended December 31, 2016 versus a $2,210,000 reversal of provision for loan losses during the year ended December 31, 2015. The increase in the reversal of provision for loan losses for the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily the result of an increase in net loan recoveries from 0.07% of average loans during 2015 to 0.09% of average loans during 2016, a decrease in nonperforming loans from $37,119,000 at December 31, 2015 to $20,128,000 at December 31, 2016, continued improvement in loan portfolio loss history, and improvements in collateral values and estimated cash flows related to nonperforming loans and purchased credit impaired loans. As shown in the Table labeled “Allowance for 29 Loan Losses - year ended December 31, 2016” at Note 5 in Item 8 of Part II of this report, residential real estate loans, home equity lines of credit, home equity loans, and commercial construction loans experienced a reversal of provision for loan losses during the year ended December 31, 2016. The level of provision, or reversal of provision, for loan losses of each loan category during the year ended December 31, 2016 was due primarily to a decrease in the required allowance for loan losses as of December 31, 2016 when compared to the required allowance for loan losses as of December 31, 2015 less net charge-offs during the year ended December 31, 2016. All categories of loans except commercial real estate mortgage loans, C & I loans, and residential construction loans experienced a decrease in the required allowance for loan losses during the year ended December 31, 2016. These decreases in required allowance for loan losses were due primarily to reduced impaired loans, improvements in estimated cash flows and collateral values for the remaining and newly impaired loans, and reductions in historical loss factors that, in part, determine the required loan loss allowance for performing loans in accordance with the Company’s allowance for loan losses methodology as described under the heading “Loans and Allowance for Loan Losses” at Note 1 in Item 8 of Part II of this report. These same factors were also present, to some extent, for commercial real estate mortgage loans, C & I loans, and residential construction loans, but were more than offset by the effect of increased loan balances in these loan categories resulting in net provisions for loan losses in these categories during the year ended December 31, 2016. The provision for loan losses related to Originated and PNCI loans is based on management’s evaluation of inherent risks in these loan portfolios and a corresponding analysis of the allowance for loan losses. The provision for loan losses related to PCI loan portfolio is based on changes in estimated cash flows expected to be collected on PCI loans. Additional discussion on loan quality, our procedures to measure loan impairment, and the allowance for loan losses is provided under the heading “Asset Quality and Non-Performing Assets” below. Management re-evaluates the loss ratios and other assumptions used in its calculation of the allowance for loan losses for its Originated and PNCI loan portfolios on a quarterly basis and makes changes as appropriate based upon, among other things, changes in loss rates experienced, collateral support for underlying loans, changes and trends in the economy, and changes in the loan mix. Management also re-evaluates expected cash flows used in its accounting for its PCI loan portfolio, including any required allowance for loan losses, on a quarterly basis and makes changes as appropriate based upon, among other things, changes in loan repayment experience, changes in loss rates experienced, and collateral support for underlying loans. Noninterest Income The following table summarizes the Company’s noninterest income for the periods indicated (dollars in thousands): Service charges on deposit accounts ATM and interchange fees Other service fees Mortgage banking service fees Change in value of mortgage servicing rights Total service charges and fees Gain on sale of loans Commissions on sale of non-deposit investment products Increase in cash value of life insurance Gain on sale of investments Lease brokerage income Gain on sale of foreclosed assets Change in indemnification asset Sale of customer checks Life insurance benefit in excess of cash value Loss on disposal of fixed assets Other Total other noninterest income Total noninterest income 2017 $16,056 16,727 3,282 2,076 (718) Years Ended December 31, 2016 $14,365 15,859 3,121 2,065 (2,184) 33,226 4,037 2,329 2,717 — 711 262 (493) 408 238 (147) 1,275 11,337 $44,563 37,423 3,109 2,729 2,685 961 782 711 490 372 108 (142) 793 12,598 $50,021 2015 $14,276 13,364 2,977 2,164 (701) 32,080 3,064 3,349 2,786 — 712 991 (207) 492 155 (129) 2,054 13,267 $45,347 Noninterest income increased $5,458,000 (12.2%) to $50,021,000 in 2017 compared to 2016. The increase in noninterest income was due primarily to an increase in service charges on deposit accounts of $1,691,000 (11.8%) to $16,056,000, an increase in ATM fees and interchange revenue of $868,000 (5.5%) to $16,727,000, an increase of $1,466,000 in change in value of mortgage servicing rights, a $961,000 increase in gain on sale of investments, which were partially offset by a $928,000 (23.0%) decrease in gain on sale of loans, and a $482,000 (37.8%) decrease in other noninterest income. The $1,691,000 increase in service charges on deposit accounts was due primarily to increased fee generation from both consumer and business checking customers. The $868,000 increase in ATM fees and interchange revenue was due primarily to the Company’s continued focus in this area, and growth in electronic payments volume. The $1,466,000 improvement in change in value of mortgage servicing rights (MSRs) was due primarily to a decrease in the market rate of return for such servicing 30 rights thus increasing their value at December 31, 2017 compared to December 31, 2016. The $961,000 gain on sale of investment securities was due to the Company’s decision to sell $24,796,000 of investment securities during the three months ended September 30, 2017 while no investment sales were made during 2016. The $983,000 increase in change in indemnification agreement was the result of the termination of its indemnification agreements with the FDIC during 2017. The $928,000 decrease in gain on sale of loans was due primarily to reduced residential mortgage refinance activity in 2017 compared to 2016. Noninterest income decreased $784,000 (1.7%) to $44,563,000 in 2016 compared to 2015. The decrease in noninterest income was due primarily to $870,000 of recoveries of loans from acquired institutions that were charged off prior to acquisition of those institutions by the Company that were recorded in other noninterest income during the year ended December 31, 2015, a $1,483,000 decrease in change in value of mortgage servicing rights, a $1,020,000 decrease in commissions on sale of nondeposit investment products, and a $729,000 decrease in gain on sale of foreclosed assets that were partially offset by a $2,495,000 increase in ATM fees and interchange income and a $973,000 increase in gain on sale of loans. The decrease in change in value of mortgage servicing rights (MSRs) is primarily due to a change in the required rate of return on MSRs by market participants and a decrease in estimated future MSR cash flows as a result of reduced mortgage rates and higher rates of early mortgage payoffs from mortgage refinancing, both of which reduced the value of such MSRs during the year ended December 31, 2016 compared to a smaller decrease in the value of MSRs during the year ended December 31, 2015 that was primarily due to a decrease in estimated future MSR cash flows as a result of reduced mortgage rates and higher rates of early mortgage payoffs from mortgage refinancing. The decrease in gain on sale of foreclosed assets was due to decreased foreclosed asset sales during the year ended December 31, 2016, and the uniqueness of individual foreclosed asset sales when compared to the year-ago period. The $2,495,000 increase in ATM fees and interchange revenue was primarily due to the Company’s increased focus in this area, including the introduction of new services in this area during the quarter ended March 31, 2016. The $973,000 increase in gain on sale of loans was due to continued high levels of refinance and home purchase activity, and increased focus in this area by the Company. The $4,037,000 of gain on sale of loans during 2016 included $3,729,000 of gain on sale of residential real estate loans originated for sale, and $308,000 of gain on sale of loans not originated for sale. The changes in noninterest income include the effects from the operation of three branches, including $161,231,000 of deposits, acquired from Bank of America on March 18, 2016. Noninterest Expense The following table summarizes the Company’s other noninterest expense for the periods indicated (dollars in thousands): The components of noninterest expense were as follows (in thousands): Base salaries, net of deferred loan origination costs Incentive compensation Benefits and other compensation costs Total salaries and benefits expense Occupancy Data processing and software Equipment ATM & POS network charges Advertising Professional fees Telecommunications Assessments Operational losses Intangible amortization Postage Courier service Change in reserve for unfunded commitments Foreclosed assets expense Provision for foreclosed asset losses Legal settlement Merger & acquisition expense Miscellaneous other Total other noninterest expense Total noninterest expense 31 2017 $ 54,589 9,227 19,114 82,930 10,894 10,448 7,141 4,752 4,101 3,745 2,713 1,676 1,394 1,389 1,296 1,035 445 231 162 — 530 12,142 64,094 $147,024 Years Ended December 31, 2016 $ 53,169 8,872 18,683 80,724 10,139 8,846 6,597 4,999 3,829 5,409 2,749 2,105 1,564 1,377 1,603 998 244 266 140 1,450 784 12,174 65,273 $145,997 2015 $ 46,822 6,964 17,619 71,405 10,126 7,670 5,997 4,190 3,992 4,545 3,007 2,572 737 1,157 1,296 1,154 330 490 502 — 586 11,085 59,436 $130,841 Merger and acquisition expense: Base salaries, net of loan origination costs Data processing and software Professional fees Other Total merger expense Average full time equivalent staff Noninterest expense to revenue (FTE) — — $ 513 17 $ 530 1,000 64.7% $ 187 — 342 255 $ 784 999 67.9% — $ 108 120 358 $ 586 949 64.7% Salary and benefit expenses increased $2,206,000 (2.7%) to $82,930,000 during the year ended December 31, 2017 compared to the year ended December 31, 2016. Base salaries, incentive compensation and benefits & other compensation expense increased $1,420,000 (2.7%), 355,000 (4.0%), and 431,000 (2.3%), respectively, to $54,589,000, $9,227,000 and $19,114,000, respectively, during the year ended December 31, 2017. The increases in these categories of salary and benefits expense are primarily due to annual merit increases. The average number of full-time equivalent staff increased 1 (0.1%) from 999 during the year ended December 31, 2016 to 1,000 for the year ended December 31, 2017. Salary and benefit expenses increased $9,319,000 (13.1%) to $80,724,000 during the year ended December 31, 2016 compared to the year ended December 31, 2015. Base salaries, incentive compensation and benefits & other compensation expense increased $6,347,000 (13.6%), 1,908,000 (27.4%), and 1,064,000 (6.0%), respectively, to $53,169,000, $8,872,000 and $18,683,000, respectively, during the year ended December 31, 2016. The average number of full-time equivalent staff increased 50 (5.3%) from 949 during the year ended December 31, 2015 to 999 for the year ended December 31, 2016. The increase in base salaries was due primarily to annual pay raises, an increase in average full-time equivalent staff, and a $1,409,000 increase in temporary help expense from $63,000 during 2015 to $1,472,000 during 2016. The increase in temporary help expense was due primarily to an expansion of the Bank’s customer call center capacity during 2016. All categories of incentive compensation expense increased during 2016 compared to 2015 due to related production and profitability measures, and the general increase in staff, except for commissions on sale of nondeposit investment products for which production was down compared to 2015. The increase in benefits and other compensation expense was due primarily to the increase in full-time equivalent staff during 2016. Other noninterest expense decreased $1,179,000 (1.8%) to $64,094,000 during the year ended December 31, 2017 compared to the year ended December 31, 2016. The decrease in other noninterest expense was due primarily to a $1,664,000 (30.8%) decrease in professional fees, and a $1,450,000 decrease in litigation contingent liability expense, that were partially offset by a $1,602,000 (18.1%) increase in data processing and software expense, a $755,000 (7.4%) increase in occupancy expense, and a $544,000 (8.2%) increase in equipment expense. The $1,664,000 decrease in professional fees was due primarily to consulting fees related to system conversions during 2016. The $1,450,000 decrease in litigation contingent liability expense was due to a single specific liability incurred during 2016. The $1,602,000 increase in data processing and software expense was due primarily to data system outsourcing and enhancements that occurred throughout 2016, and early 2017. The $755,000 increase in occupancy expense was due primarily to increases in building maintenance and remodel, and lease expense. The $544,000 increase in equipment expense was due primarily to increased depreciation expense related to technology and other equipment, and furniture. Other noninterest expense increased $5,837,000 (9.8%) to $65,273,000 during the year ended December 31, 2016 compared to the year ended December 31, 2015. The increase in other noninterest expense was primarily due to system conversion and capacity expansion expenses during 2016. Expense categories including equipment, data processing and software, ATM & POS network charges and professional (consulting) experienced significant increases due primarily to system conversion and capacity expansion during 2016. The Company recorded a litigation contingency expense of $1,450,000 during 2016. The details of this contingency can be found at Note 18 in Item 8 of Part II of this report. Assessments expense decrease $467,000 (18.2%) to $2,105,000 during 2016 compared to $2,572,000 during 2015 due to a decrease in FDIC insurance premiums during the three months ended September 30, 2016. Nonrecurring expenses related to the acquisition of three branches from Bank of America in March 2016 totaling $784,000 and the acquisition of North Valley Bancorp in October 2014 are included in other noninterest expense for the years ended December 31, 2016 and 2015, respectively. Included in miscellaneous other noninterest expense during 2016 were $782,000 valuation allowance expenses on fixed assets transferred to held for sale including a $716,000 valuation allowance expense related to a closed branch building held for sale, the value of which was written down to current market value, and subsequently sold during the three months ended September 30, 2016. Net proceeds from the sale of this building were $1,218,000, and resulted in no gain or additional loss being recorded upon the sale of this building. 32 Income Taxes On December 22, 2017, President Donald Trump signed into law “H.R.1”, commonly known as the “Tax Cuts and Jobs Act”, which among other items reduces the Federal corporate tax rate from 35% to 21% effective January 1, 2018. While this decrease in the Federal corporate tax rate is expected to have a positive impact on the Company’s net income beginning January 1, 2018, the enactment of the law during 2017 required the Company to re-measure its deferred tax assets and liabilities. The Company concluded that this caused the Company’s net deferred tax asset to be reduced, and Federal income tax expense to be increased by $7,416,000 during the fourth quarter of 2017. Additionally, amortization expense of the low income housing tax credit investments was accelerated by $226,000. The provisions for income taxes applicable to income before taxes for the years ended December 31, 2017, 2016 and 2015 differ from amounts computed by applying the statutory Federal income tax rates to income before taxes. The effective tax rate and the statutory federal income tax rate are reconciled as follows: Federal statutory income tax rate State income taxes, net of federal tax benefit Tax Cuts and Jobs Act impact on deferred measurement Tax-exempt interest on municipal obligations Tax-exempt life insurance related income Equity compensation Low income housing tax credit benefits Low income housing tax credit amortization Non-deductible joint beneficiary agreement expense Non-deductible merger expense Other Effective Tax Rate Years Ended December 31, 2016 35.0% 6.8 — (1.8) (1.3) — (1.3) 0.8 0.1 — (0.1) 38.2% 2017 35.0% 6.9 9.6 (1.9) (1.3) (1.2) (2.3) 2.1 0.1 0.2 0.5 47.7% 2015 35.0% 6.6 — (0.7) (1.3) — (0.4) — 0.1 — 0.4 39.7% The effective tax rate on income was 47.7%, 38.2%, and 39.7% in 2017, 2016, and 2015, respectively. The effective tax rate was greater than the Federal statutory tax rate due to State tax expense of $8,178,000, $7,576,000, and $7,412,000, respectively, in these years, and a $7,416,000 Federal tax expense in 2017 due to the re-measurement of the Company’s net deferred tax asset resulting from the Federal tax law change that occurred in December; and were partially offset by Federal tax-exempt investment income of $4,165,000, $3,881,000, and $1,509,000, respectively, Federal and State tax-exempt income of $2,792,000, $2,955,000, and $2,786,000, respectively, from increase in cash value and gain on death benefit of life insurance, low income housing tax credits of $142,000, $197,000, and $0, respectively, and equity compensation excess tax benefits of $906,000, $0, and $0, respectively. The low income housing tax credits and the equity compensation excess tax benefits represent direct reductions in tax expense. The items noted above resulted in an effective combined Federal and State income tax rate that differed from the combined Federal and State statutory income tax rate of approximately 42.0% during 2017, 2016, and 2015. Based on the Tax Cuts and Jobs Act, the Company expects its combined statutory income tax rate to be 29.6%. Financial Condition Investment Securities The following table presents the available for sale investment securities portfolio by major type as of the dates indicated: (In thousands) Investment securities available for sale (at fair value): Obligations of US government corporations and agencies Obligations of states and political subdivisions Corporate bonds Marketable equity securities Total investment securities available for sale 2017 $604,789 123,156 — 2,938 $730,883 Year ended December 31, 2015 2016 2014 $429,678 117,617 — 2,938 $550,233 $313,682 88,218 — 2,985 $404,885 $75,120 3,175 1,908 3,002 $83,205 2013 $ 97,143 5,589 1,915 — $104,647 Investment securities available for sale increased $180,650,000 to $730,883,000 as of December 31, 2017, compared to December 31, 2016. This increase is attributable to purchases of $265,806,000, maturities and principal repayments of $63,942,000, sales of investments with a cost basis of $24,796,000, a net increase in the fair value of investments securities available for sale of $5,461,000, and amortization of net purchase price premiums of $1,879,000. 33 The following table presents the held to maturity investment securities portfolio by major type as of the dates indicated: (In thousands) Investment securities held to maturity (at cost): Obligations of US government corporations and agencies Obligations of states and political subdivisions Total investment securities held to maturity 2017 Year ended December 31, 2015 2016 2014 2013 $500,271 $597,982 $711,994 $660,836 $227,864 12,640 14,536 $514,844 $602,536 $726,530 $676,426 $240,504 15,590 14,573 14,554 Investment securities held to maturity decreased $87,692,000 to $514,844,000 as of December 31, 2017, compared to December 31, 2016. This decrease is attributable to principal repayments of $86,371,000 and amortization of net purchase price discounts/premiums of $1,321,000. Additional information about the investment portfolio is provided in Note 3 in the financial statements at Item 8 of Part II of this report. Restricted Equity Securities Restricted equity securities were $16,956,000 at December 31, 2017 and December 31, 2016. The entire balance of restricted equity securities at December 31, 2017 and December 31, 2016 represents the Bank’s investment in the Federal Home Loan Bank of San Francisco (“FHLB”). FHLB stock is carried at par and does not have a readily determinable fair value. While technically these are considered equity securities, there is no market for the FHLB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB. As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. Loans The Bank concentrates its lending activities in four principal areas: real estate mortgage loans (residential and commercial loans), consumer loans, commercial loans (including agricultural loans), and real estate construction loans. The interest rates charged for the loans made by the Bank vary with the degree of risk, the size and maturity of the loans, the borrower’s relationship with the Bank and prevailing money market rates indicative of the Bank’s cost of funds. The majority of the Bank’s loans are direct loans made to individuals, farmers and local businesses. The Bank relies substantially on local promotional activity and personal contacts by bank officers, directors and employees to compete with other financial institutions. The Bank makes loans to borrowers whose applications include a sound purpose, a viable repayment source and a plan of repayment established at inception and generally backed by a secondary source of repayment. Loan Portfolio Composite The following table shows the Company’s loan balances, including net deferred loan fees, at the dates indicated: (dollars in thousands) Real estate mortgage Consumer Commercial Real estate construction Total loans, net of fees 2017 $2,300,322 356,874 220,412 137,557 $3,015,165 34 2016 $2,057,824 362,303 217,047 122,419 $2,759,593 Year ended December 31, 2015 $1,811,832 395,283 194,913 120,909 $2,522,937 2014 $1,615,359 417,084 174,945 75,136 $2,282,524 2013 $1,107,863 383,163 131,878 49,103 $1,672,007 The following table shows the Company’s loan balances, including net deferred loan fees, as a percentage of total loans at the dates indicated: Real estate mortgage Consumer Commercial Real estate construction Total loans, net of fees 2017 76.3% 11.8% 7.3% 4.6% 100.0% Year ended December 31, 2015 71.8% 15.7% 7.7% 4.8% 100.0% 2016 74.6% 13.1% 7.9% 4.4% 100.0% 2014 70.7% 18.3% 7.7% 3.3% 100.0% 2013 66.3% 22.9% 7.9% 2.9% 100.0% At December 31, 2017 loans, including net deferred loan costs, totaled $3,015,165,000 which was a 9.3% ($255,572,000) increase over the balances at the end of 2016. Demand for all categories of loans was strong to moderate during 2017. At December 31, 2016 loans, including net deferred loan costs, totaled $2,759,593,000 which was a 9.4% ($236,656,000) increase over the balances at the end of 2015. Demand for commercial real estate (real estate mortgage) loans was strong during 2016. Demand for residential mortgage loans was strong during 2016. Demand for home equity loans and lines of credit was moderate during 2016. At December 31, 2015 loans, including net deferred loan costs, totaled $2,522,937,000 which was a 10.5% ($240,413,000) increase over the balances at the end of 2014. Demand for commercial real estate (real estate mortgage) loans was strong during 2015. Demand for home equity loans and lines of credit was weak during 2015. Asset Quality and Nonperforming Assets Nonperforming Assets Loans originated by the Company, i.e., not purchased or acquired in a business combination, are referred to as originated loans. Originated loans are reported at the principal amount outstanding, net of deferred loan fees and costs. Loan origination and commitment fees and certain direct loan origination costs are deferred, and the net amount is amortized as an adjustment of the related loan’s yield over the actual life of the loan. Originated loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Originated loans are placed in nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal, or a loan becomes contractually past due by 90 days or more with respect to interest or principal and is not well secured and in the process of collection. When an originated loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loan is estimated to be fully collectible as to both principal and interest. An allowance for loan losses for originated loans is established through a provision for loan losses charged to expense. Originated loans and deposit related overdrafts are charged against the allowance for loan losses when management believes that the collectability of the principal is unlikely or, with respect to consumer installment loans, according to an established delinquency schedule. The allowance is an amount that management believes will be adequate to absorb probable losses inherent in existing loans and leases, based on evaluations of the collectability, impairment and prior loss experience of loans and leases. The evaluations take into consideration such factors as changes in the nature and size of the portfolio, overall portfolio quality, loan concentrations, specific problem loans, and current economic conditions that may affect the borrower’s ability to pay. The Company defines an originated loan as impaired when it is probable the Company will be unable to collect all amounts due according to the original contractual terms of the loan agreement. Impaired originated loans are measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate. As a practical expedient, impairment may be measured based on the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. When the measure of the impaired loan is less than the recorded investment in the loan, the impairment is recorded through a valuation allowance. In situations related to originated loans where, for economic or legal reasons related to a borrower’s financial difficulties, the Company grants a concession for other than an insignificant period of time to the borrower that the Company would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). The Company strives to identify borrowers in financial difficulty early and work with them to modify to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where the Company grants the borrower new terms that result in the loan being classified as a TDR, the Company measures any impairment on the restructuring as noted above for impaired loans. TDR loans are classified as impaired until they are fully paid off or charged off. Loans that are in nonaccrual status at the time they become TDR loans, remain in nonaccrual status 35 until the borrower demonstrates a sustained period of performance which the Company generally believes to be six consecutive months of payments, or equivalent. Otherwise, TDR loans are subject to the same nonaccrual and charge-off policies as noted above with respect to their restructured principal balance. Credit risk is inherent in the business of lending. As a result, the Company maintains an allowance for loan losses to absorb losses inherent in the Company’s originated loan portfolio. This is maintained through periodic charges to earnings. These charges are included in the Consolidated Statements of Income as provision for loan losses. All specifically identifiable and quantifiable losses are immediately charged off against the allowance. However, for a variety of reasons, not all losses are immediately known to the Company and, of those that are known, the full extent of the loss may not be quantifiable at that point in time. The balance of the Company’s allowance for originated loan losses is meant to be an estimate of these unknown but probable losses inherent in the portfolio. The Company formally assesses the adequacy of the allowance for originated loan losses on a quarterly basis. Determination of the adequacy is based on ongoing assessments of the probable risk in the outstanding originated loan portfolio, and to a lesser extent the Company’s originated loan commitments. These assessments include the periodic re-grading of credits based on changes in their individual credit characteristics including delinquency, seasoning, recent financial performance of the borrower, economic factors, changes in the interest rate environment, growth of the portfolio as a whole or by segment, and other factors as warranted. Loans are initially graded when originated. They are re-graded as they are renewed, when there is a new loan to the same borrower, when identified facts demonstrate heightened risk of nonpayment, or if they become delinquent. Re-grading of larger problem loans occurs at least quarterly. Confirmation of the quality of the grading process is obtained by independent credit reviews conducted by consultants specifically hired for this purpose and by various bank regulatory agencies. The Company’s method for assessing the appropriateness of the allowance for originated loan losses includes specific allowances for impaired originated loans and leases, formula allowance factors for pools of credits, and allowances for changing environmental factors (e.g., interest rates, growth, economic conditions, etc.). Allowance factors for loan pools were based on historical loss experience by product type and prior risk rating. Loans purchased or acquired in a business combination are referred to as acquired loans. Acquired loans are valued as of acquisition date in accordance with Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) Topic 805, Business Combinations. Loans acquired with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are referred to as purchased credit impaired (PCI) loans. PCI loans are accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. Under FASB ASC Topic 805 and FASB ASC Topic 310-30, PCI loans are recorded at fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date. Fair value is defined as the present value of the future estimated principal and interest payments of the loan, with the discount rate used in the present value calculation representing the estimated effective yield of the loan. Default rates, loss severity, and prepayment speed assumptions are periodically reassessed and our estimate of future payments is adjusted accordingly. The difference between contractual future payments and estimated future payments is referred to as the nonaccretable difference. The difference between estimated future payments and the present value of the estimated future payments is referred to as the accretable yield. The accretable yield represents the amount that is expected to be recorded as interest income over the remaining life of the loan. If after acquisition, the Company determines that the estimated future cash flows of a PCI loan are expected to be more than the originally estimated, an increase in the discount rate (effective yield) would be made such that the newly increased accretable yield would be recognized, on a level yield basis, over the remaining estimated life of the loan. If, after acquisition, the Company determines that the estimated future cash flows of a PCI loan are expected to be less than the previously estimated, the discount rate would first be reduced until the present value of the reduced cash flow estimate equals the previous present value however, the discount rate may not be lowered below its original level at acquisition. If the discount rate has been lowered to its original level and the present value has not been sufficiently lowered, an allowance for loan loss would be established through a provision for loan losses charged to expense to decrease the present value to the required level. If the estimated cash flows improve after an allowance has been established for a loan, the allowance may be partially or fully reversed depending on the improvement in the estimated cash flows. Only after the allowance has been fully reversed may the discount rate be increased. PCI loans are put on nonaccrual status when cash flows cannot be reasonably estimated. PCI loans on nonaccrual status are accounted for using the cost recovery method or cash basis method of income recognition. PCI loans are charged off when evidence suggests cash flows are not recoverable. Foreclosed assets from PCI loans are recorded in foreclosed assets at fair value with the fair value at time of foreclosure representing cash flow from the loan. ASC 310-30 allows PCI loans with similar risk characteristics and acquisition time frame to be “pooled” and have their cash flows aggregated as if they were one loan. The Company elected to use the “pooled” method of ASC 310-30 for PCI – other loans in the acquisition of certain assets and liabilities of Granite Community Bank, N.A. (“Granite”) in 2010 and Citizens Bank of Northern California (“Citizens”) in 2011. Acquired loans that are not PCI loans are referred to as purchased not credit impaired (PNCI) loans. PNCI loans are accounted for under FASB ASC Topic 310-20, Receivables – Nonrefundable Fees and Other Costs, in which interest income is accrued on a level-yield basis for performing loans. For income recognition purposes, this method assumes that all 36 contractual cash flows will be collected, and no allowance for loan losses is established at the time of acquisition. Post-acquisition date, an allowance for loan losses may need to be established for acquired loans through a provision charged to earnings for credit losses incurred subsequent to acquisition. Under ASC 310-20, the loss would be measured based on the probable shortfall in relation to the contractual note requirements, consistent with our allowance for loan loss policy for similar loans. When referring to PNCI and PCI loans we use the terms “nonaccretable difference”, “accretable yield”, or “purchase discount”. Nonaccretable difference is the difference between undiscounted contractual cash flows due and undiscounted cash flows we expect to collect, or put another way, it is the undiscounted contractual cash flows we do not expect to collect. Accretable yield is the difference between undiscounted cash flows we expect to collect and the value at which we have recorded the loan on our financial statements. On the date of acquisition, all purchased loans are recorded on our consolidated financial statements at estimated fair value. Purchase discount is the difference between the estimated fair value of loans on the date of acquisition and the principal amount owed by the borrower, net of charge offs, on the date of acquisition. We may also refer to “discounts to principal balance of loans owed, net of charge-offs”. Discounts to principal balance of loans owed, net of charge-offs is the difference between principal balance of loans owed, net of charge-offs, and loans as recorded on our financial statements. Discounts to principal balance of loans owed, net of charge-offs arise from purchase discounts, and equal the purchase discount on the acquisition date. Loans are also categorized as “covered” or “noncovered”. Covered loans refer to loans covered by a FDIC loss sharing agreement. Noncovered loans refer to loans not covered by a FDIC loss sharing agreement. Originated loans and PNCI loans are reviewed on an individual basis for reclassification to nonaccrual status when any one of the following occurs: the loan becomes 90 days past due as to interest or principal, the full and timely collection of additional interest or principal becomes uncertain, the loan is classified as doubtful by internal credit review or bank regulatory agencies, a portion of the principal balance has been charged off, or the Company takes possession of the collateral. Loans that are placed on nonaccrual even though the borrowers continue to repay the loans as scheduled are classified as “performing nonaccrual” and are included in total nonperforming loans. The reclassification of loans as nonaccrual does not necessarily reflect management’s judgment as to whether they are collectible. Interest income on originated nonaccrual loans that would have been recognized during the years ended December 31, 2017, 2016, and 2015, if all such loans had been current in accordance with their original terms, totaled $1,067,000, $783,000, and $1,840,000, respectively. Interest income actually recognized on these originated loans during the years ended December 31, 2017, 2016, and 2015 was $530,000, $377,000, and $170,000, respectively. Interest income on PNCI nonaccrual loans that would have been recognized during the years ended December 31, 2017, 2016, and 2015, if all such loans had been current in accordance with their original terms, totaled $73,000, $178,000, and $386,000, respectively. Interest income actually recognized on these PNCI loans during the years ended December 31, 2017, 2016, and 2015 was $18,000, $11,000, and $205,000, respectively. The Company’s policy is to place originated loans and PNCI loans 90 days or more past due on nonaccrual status. In some instances when an originated loan is 90 days past due Management does not place it on nonaccrual status because the loan is well secured and in the process of collection. A loan is considered to be in the process of collection if, based on a probable specific event, it is expected that the loan will be repaid or brought current. Generally, this collection period would not exceed 30 days. Loans where the collateral has been repossessed are classified as foreclosed assets. Management considers both the adequacy of the collateral and the other resources of the borrower in determining the steps to be taken to collect nonaccrual loans. Alternatives that are considered are foreclosure, collecting on guarantees, restructuring the loan or collection lawsuits. 37 The following table set forth the amount of the Bank’s nonperforming assets as of the dates indicated.

Loan charge-offs during the three months ended March 31, 2017 In the first quarter of 2017, the Company recorded $306,000 in loan charge-offs and $103,000 in deposit overdraft charge-offs less $406,000 in loan recoveries and $74,000 in deposit overdraft recoveries resulting in $71,000 of net recoveries. Primary causes of the loan charges taken in the first quarter of 2017 were gross charge-offs of $102,000 on five home equity lines and loans, $71,000 on 12 other consumer loans, and $133,000 on five C&I loans. Total charge-offs were generally comprised of individual charges of less than $250,000 each. Generally losses are triggered by non-performance by the borrower and calculated based on any difference between the current loan amount and the current value of the underlying collateral less any estimated costs associated with the disposition of the collateral. Allowance for Loan Losses The Company’s allowance for loan losses is comprised of allowances for originated, PNCI and PCI loans. All such allowances are established through a provision for loan losses charged to expense. Originated and PNCI loans, and deposit related overdrafts are charged against the allowance for originated loan losses when Management believes that the collectability of the principal is unlikely or, with respect to consumer installment loans, according to an established delinquency schedule. The allowances for originated and PNCI loan losses are amounts that Management believes will be adequate to absorb probable losses inherent in existing originated loans, based on evaluations of the collectability, impairment and prior loss experience of those loans and leases. The evaluations take into consideration such factors as changes in the nature and size of the portfolio, overall portfolio quality, loan concentrations, specific problem loans, and current economic conditions that may affect the borrower’s ability to pay. The Company defines an originated or PNCI loan as impaired when it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired originated and PNCI loans are measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate. As a practical expedient, impairment may be measured based on the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. When the measure of the impaired loan is less than the recorded investment in the loan, the impairment is recorded through a valuation allowance. 43 In situations related to originated and PNCI loans where, for economic or legal reasons related to a borrower’s financial difficulties, the Company grants a concession for other than an insignificant period of time to the borrower that the Company would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). The Company strives to identify borrowers in financial difficulty early and work with them to modify to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where the Company grants the borrower new terms that provide for a reduction of either interest or principal, the Company measures any impairment on the restructuring as noted above for impaired loans. TDR loans are classified as impaired until they are fully paid off or charged off. Loans that are in nonaccrual status at the time they become TDR loans, remain in nonaccrual status until the borrower demonstrates a sustained period of performance which the Company generally believes to be six consecutive months of payments, or equivalent. Otherwise, TDR loans are subject to the same nonaccrual and charge-off policies as noted above with respect to their restructured principal balance. Credit risk is inherent in the business of lending. As a result, the Company maintains an allowance for loan losses to absorb incurred losses inherent in the Company’s originated and PNCI loan portfolios. These are maintained through periodic charges to earnings. These charges are included in the Consolidated Income Statements as provision for loan losses. All specifically identifiable and quantifiable losses are immediately charged off against the allowance. However, for a variety of reasons, not all losses are immediately known to the Company and, of those that are known, the full extent of the loss may not be quantifiable at that point in time. The balance of the Company’s allowances for originated and PNCI loan losses are meant to be an estimate of these unknown but probable losses inherent in these portfolios. The Company formally assesses the adequacy of the allowance for originated and PNCI loan losses on a quarterly basis. Determination of the adequacy is based on ongoing assessments of the probable risk in the outstanding originated and PNCI loan portfolios, and to a lesser extent the Company’s originated and PNCI loan commitments. These assessments include the periodic re-grading of credits based on changes in their individual credit characteristics including delinquency, seasoning, recent financial performance of the borrower, economic factors, changes in the interest rate environment, growth of the portfolio as a whole or by segment, and other factors as warranted. Loans are initially graded when originated or acquired. They are re-graded as they are renewed, when there is a new loan to the same borrower, when identified facts demonstrate heightened risk of nonpayment, or if they become delinquent. Re-grading of larger problem loans occurs at least quarterly. Confirmation of the quality of the grading process is obtained by independent credit reviews conducted by consultants specifically hired for this purpose and by various bank regulatory agencies. The Company’s method for assessing the appropriateness of the allowance for originated and PNCI loan losses includes specific allowances for impaired loans and leases, formula allowance factors for pools of credits, and allowances for changing environmental factors (e.g., interest rates, growth, economic conditions, etc.). Allowance factors for loan pools are based on historical loss experience by product type and prior risk rating. Allowances for impaired loans are based on analysis of individual credits. Allowances for changing environmental factors are Management’s best estimate of the probable impact these changes have had on the originated or PNCI loan portfolio as a whole. The allowances for originated and PNCI loans are included in the allowance for loan losses. As noted above, the allowances for originated and PNCI loan losses consists of a specific allowance, a formula allowance, and an allowance for environmental factors. The first component, the specific allowance, results from the analysis of identified credits that meet management’s criteria for specific evaluation. These loans are reviewed individually to determine if such loans are considered impaired. Impaired loans are those where management has concluded that it is probable that the borrower will be unable to pay all amounts due under the original contractual terms. Impaired loans are specifically reviewed and evaluated individually by management for loss potential by evaluating sources of repayment, including collateral as applicable, and a specified allowance for loan losses is established where necessary. The second component of the allowance for originated and PNCI loan losses, the formula allowance, is an estimate of the probable losses that have occurred across the major loan categories in the Company’s originated and PNCI loan portfolios. This analysis is based on loan grades by pool and the loss history of these pools. This analysis covers the Company’s entire originated and PNCI loan portfolios including unused commitments but excludes any loans that were analyzed individually and assigned a specific allowance as discussed above. The total amount allocated for this component is determined by applying loss estimation factors to outstanding loans and loan commitments. The loss factors were previously based primarily on the Company’s historical loss experience tracked over a five-year period and adjusted as appropriate for the input of current trends and events. Because historical loss experience varies for the different categories of originated loans, the loss factors applied to each category also differed. In addition, there is a greater chance that the Company would suffer a loss from a loan that was risk rated less than satisfactory than if the loan was last graded satisfactory. Therefore, for any given category, a larger loss estimation factor was applied to less than satisfactory loans than to those that the Company last graded as satisfactory. The resulting formula allowance was the sum of the allocations determined in this manner. 44 The third component of the allowances for originated and PNCI loan losses, the environmental factor allowance, is a component that is not allocated to specific loans or groups of loans, but rather is intended to absorb losses that may not be provided for by the other components. There are several primary reasons that the other components discussed above might not be sufficient to absorb the losses present in the originated and PNCI loan portfolios, and the environmental factor allowance is used to provide for the losses that have occurred because of them. The first reason is that there are limitations to any credit risk grading process. The volume of originated and PNCI loans makes it impractical to re-grade every loan every quarter. Therefore, it is possible that some currently performing originated or PNCI loans not recently graded will not be as strong as their last grading and an insufficient portion of the allowance will have been allocated to them. Grading and loan review often must be done without knowing whether all relevant facts are at hand. Troubled borrowers may deliberately or inadvertently omit important information from reports or conversations with lending officers regarding their financial condition and the diminished strength of repayment sources. The second reason is that the loss estimation factors are based primarily on historical loss totals. As such, the factors may not give sufficient weight to such considerations as the current general economic and business conditions that affect the Company’s borrowers and specific industry conditions that affect borrowers in that industry. The factors might also not give sufficient weight to other environmental factors such as changing economic conditions and interest rates, portfolio growth, entrance into new markets or products, and other characteristics as may be determined by Management. Specifically, in assessing how much environmental factor allowance needed to be provided, management considered the following: • with respect to the economy, management considered the effects of changes in GDP, unemployment, CPI, debt statistics, housing starts, home affordability, and other economic factors which serve as indicators of economic health and trends and which may have an impact on the performance of our borrowers, and • with respect to changes in the interest rate environment, management considered the recent changes in interest rates and the resultant economic impact it may have had on borrowers with high leverage and/or low profitability; and • with respect to changes in energy prices, management considered the effect that increases, decreases or volatility may have on the performance of our borrowers, and • with respect to loans to borrowers in new markets and growth in general, management considered the relatively short seasoning of such loans and the lack of experience with such borrowers, and • with respect to loans that have not yet been identified as impaired, management considered the volume and severity of past due loans, and • with respect to concentrations within the portfolio, management considered the risk introduced by concentrations among specific segments of the portfolio, underlying collateral types, borrowers or group of borrowers, and geographic areas. Each of these considerations was assigned a factor and applied to a portion or the entire originated and PNCI loan portfolios. Since these factors are not derived from experience and are applied to large non-homogeneous groups of loans, they are available for use across the portfolio as a whole. Acquired loans are valued as of their acquisition date in accordance with FASB ASC Topic 805, Business Combinations. Loans purchased with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are referred to as purchased credit impaired (PCI) loans. PCI loans are accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. In addition, because of the significant credit discounts associated with the loans acquired in the Granite acquisition, the Company elected to account for all loans acquired in the Granite acquisition under FASB ASC Topic 310-30, and classify them all as PCI loans. Under FASB ASC Topic 805 and FASB ASC Topic 310-30, PCI loans are recorded at fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date. Fair value is defined as the present value of the future estimated principal and interest payments of the loan, with the discount rate used in the present value calculation representing the estimated effective yield of the loan. The difference between contractual future payments and estimated future payments is referred to as the nonaccretable difference. The difference between estimated future payments and the present value of the estimated future payments is referred to as the accretable yield. The accretable yield represents the amount that is expected to be recorded as interest income over the remaining life of the loan. If after acquisition, the Company determines that the future cash flows of a PCI loan are expected to be more than the originally estimated, an increase in the discount rate (effective yield) would be made such that the newly increased accretable yield would be recognized, on a level yield basis, over the remaining estimated life of the loan. If after acquisition, the Company determines that the future cash flows of a PCI loan are expected to be less than the previously estimated, the discount rate would first be reduced until the present value of the reduced cash flow estimate equals the previous present value however, the discount rate may not be lowered below its original level. If the discount rate has been lowered to its original level and the present value has not been sufficiently lowered, an allowance for 45 loan loss would be established through a provision for loan losses charged to expense to decrease the present value to the required level. If the estimated cash flows improve after an allowance has been established for a loan, the allowance may be partially or fully reversed depending on the improvement in the estimated cash flows. Only after the allowance has been fully reversed may the discount rate be increased. PCI loans are put on nonaccrual status when cash flows cannot be reasonably estimated. PCI loans are charged off when evidence suggests cash flows are not recoverable. Foreclosed assets from PCI loans are recorded in foreclosed assets at fair value with the fair value at time of foreclosure representing cash flow from the loan. ASC 310-30 allows PCI loans with similar risk characteristics and acquisition time frame to be “pooled” and have their cash flows aggregated as if they were one loan.

Management believes that the Company’s capital is adequate to support anticipated growth, meet the cash dividend requirements of the Company and meet the future risk-based capital requirements of the Bank and the Company. Market Risk Management Overview. The goal for managing the assets and liabilities of the Bank is to maximize shareholder value and earnings while maintaining a high quality balance sheet without exposing the Bank to undue interest rate risk. The Board of Directors has overall responsibility for the Company’s interest rate risk management policies. The Bank has an Asset and Liability Management Committee (ALCO) which establishes and monitors guidelines to control the sensitivity of earnings to changes in interest rates. Asset/Liability Management. Activities involved in asset/liability management include but are not limited to lending, accepting and placing deposits, investing in securities and issuing debt. Interest rate risk is the primary market risk associated with asset/liability management. Sensitivity of earnings to interest rate changes arises when yields on assets change in a different time period or in a different amount from that of interest costs on liabilities. To mitigate interest rate risk, the structure of the balance sheet is managed with the goal that movements of interest rates on assets and liabilities are correlated and contribute to earnings even in periods of volatile interest rates. The asset/liability management policy sets limits on the acceptable amount of variance in net interest margin and market value of equity under changing interest environments. Market value of equity is the net present value of estimated cash flows from the Bank’s assets, liabilities and off-balance sheet items. The Bank uses simulation models to forecast net interest margin and market value of equity. Simulation of net interest margin and market value of equity under various interest rate scenarios is the primary tool used to measure interest rate risk. The Bank estimated the potential impact of changing interest rates on net interest margin and market value of equity using computer modeling techniques. A balance sheet forecast is prepared using inputs of actual loan, securities and interest-bearing liability (i.e. deposits/borrowings) positions as the beginning base. In the simulation of net interest income, the forecast balance sheet is processed against various interest rate scenarios. These various interest rate scenarios include a flat rate scenario, which assumes interest rates are unchanged in the future, and rate ramp scenarios including -100, +100, and +200 basis points around the flat scenario. These ramp scenarios assume that interest rates increase or decrease evenly (in a “ramp” fashion) over a twelve-month period and remain at the new levels beyond twelve months. 49 The following table summarizes the estimated effect on net interest income and net income due to changing interest rates as measured against a flat rate (no interest rate change) scenario over the succeeding twelve month period. The simulation results shown below assume no changes in the structure of the Company’s balance sheet over the twelve months being measured (a “flat” balance sheet scenario), and that deposit rates will track general interest rate changes by approximately 50%: Interest Rate Risk Simulation of Net Interest Income and Net Income as of December 31, 2017 Change in Interest Rates (Basis Points) +200 (ramp) +100 (ramp) + 0 (flat) -100 (ramp) Estimated Change in Net Interest Income (NII) (as % of “flat” NII) (1.91%) (0.92%) — (1.81%) In the simulation of market value of equity, the forecast balance sheet is processed against various interest rate scenarios. These various interest rate scenarios include a flat rate scenario, which assumes interest rates are unchanged in the future, and rate shock scenarios including -100, +100, and +200 basis points around the flat scenario. These rate shock scenarios assume that interest rates increase or decrease immediately (in a “shock” fashion) and remain at the new level in the future. The following table summarizes the estimated effect on market value of equity due to changing interest rates as measured against a flat rate (no change) scenario: Interest Rate Risk Simulation of Market Value of Equity as of December 31, 2017 Change in Interest Rates (Basis Points) +200 (shock) +100 (shock) + 0 (flat) -100 (shock) Estimated Change in Market Value of Equity (MVE) (as % of “flat” MVE) (9.6%) (3.2%) — (7.3%) These simulations indicate that given a “flat” balance sheet scenario, and if interest-bearing checking, savings and time deposit interest rates track general interest rate changes by approximately 25%, 50%, and 75%, respectively, the Company’s balance sheet is slightly liability sensitive over a twelve month time horizon for rates up, and slightly asset sensitive over a twelve month time horizon for rates down. “Liability sensitive” implies that net interest income decreases when interest rates rise and increase when interest rates decrease. “Asset sensitive” implies that net interest income increases when interest rates rise and decrease when interest rates decrease. “Neutral sensitivity” implies that net interest income does not change when interest rates change. The asset liability management policy limits aggregate market risk, as measured in this fashion, to an acceptable level within the context of risk-return trade-offs. The simulation results noted above do not incorporate any management actions that might moderate the negative consequences of interest rate deviations. In addition, the simulation results noted above contain various assumptions such as a flat balance sheet, and the rate that deposit interest rates change as general interest rates change. Therefore, they do not reflect likely actual results, but serve as estimates of interest rate risk. As with any method of measuring interest rate risk, certain shortcomings are inherent in the method of analysis presented in the preceding tables. For example, although certain of the Company’s assets and liabilities may have similar maturities or repricing time frames, they may react in different degrees to changes in market interest rates. In addition, the interest rates on certain of the Company’s asset and liability categories may precede, or lag behind, changes in market interest rates. Also, the actual rates of prepayments on loans and investments could vary significantly from the assumptions utilized in deriving the results as presented in the preceding tables. Further, a change in U.S. Treasury rates accompanied by a change in the shape of the treasury yield curve could result in different estimations from those presented herein. Accordingly, the results in the preceding tables should not be relied upon as indicative of actual results in the event of changing market interest rates. Additionally, the resulting estimates of changes in market value of equity are not intended to represent, and should not be construed to represent, estimates of changes in the underlying value of the Company. Interest rate sensitivity is a function of the repricing characteristics of the Company’s portfolio of assets and liabilities. One aspect of these repricing characteristics is the time frame within which the interest-bearing assets and liabilities are subject to change in interest rates either at replacement, repricing or maturity. An analysis of the repricing time frames of interest-bearing assets and liabilities is sometimes called a “gap” analysis because it shows the gap between assets and liabilities 50 repricing or maturing in each of a number of periods. Another aspect of these repricing characteristics is the relative magnitude of the repricing for each category of interest earning asset and interest-bearing liability given various changes in market interest rates. Gap analysis gives no indication of the relative magnitude of repricing given various changes in interest rates. Interest rate sensitivity management focuses on the maturity of assets and liabilities and their repricing during periods of changes in market interest rates. Interest rate sensitivity gaps are measured as the difference between the volumes of assets and liabilities in the Company’s current portfolio that are subject to repricing at various time horizons. The following interest rate sensitivity table shows the Company’s repricing gaps as of December 31, 2017. In this table transaction deposits, which may be repriced at will by the Company, have been included in the less than 3-month category. The inclusion of all of the transaction deposits in the less than 3-month repricing category causes the Company to appear liability sensitive. Because the Company may reprice its transaction deposits at will, transaction deposits may or may not reprice immediately with changes in interest rates. Due to the limitations of gap analysis, as described above, the Company does not actively use gap analysis in managing interest rate risk. Instead, the Company relies on the more sophisticated interest rate risk simulation model described above as its primary tool in measuring and managing interest rate risk.

These objectives can be met from either the asset or liability side of the balance sheet. Asset liquidity sources consist of the repayments and maturities of loans, selling of loans, short- term money market investments, maturities of securities and sales of securities from the available-for-sale portfolio. These activities are generally summarized as investing activities in the Consolidated Statement of Cash Flows. Net cash used by investing activities totaled $357,445,000 in 2017. Net increases in investment and loan balances used $89,736,000 and $259,404,000 of cash, respectively. Liquidity may also be generated from liabilities through deposit growth and borrowings. These activities are included under financing activities in the Consolidated Statement of Cash Flows. In 2017, financing activities provided funds totaling $201,880,000 due to a $113,571,000 increase in deposit balances, and a $104,673,000 increase in other borrowings. Dividends paid used $15,131,000 of cash during 2017. The Bank also had available correspondent banking lines of credit totaling $20,000,000 at December 31, 2017. In addition, at December 31, 2017 the Company had loans and securities available to pledge towards future borrowings from the Federal Home Loan Bank and the Federal Reserve Bank of up to $1,260,596,000 and $134,660,000, respectively. As of December 31, 2017, the Company had $122,166,000 of other borrowings as described in Note 16 of the consolidated financial statements of the Company and the related notes at Item 8 of this report. While these sources are expected to continue to provide significant amounts of funds in the future, their mix, as well as the possible use of other sources, will depend on future economic and market conditions. Liquidity is also provided or used through the results of operating activities. In 2017, operating activities provided cash of $55,381,000. The Company’s investment securities available for sale plus cash and cash equivalents in excess of reserve requirements totaled $854,243,000 at December 31, 2017, which was 17.9% of total assets at that time. This was an increase of $76,581,000 from $777,662,000 and an increase from 17.2% of total assets as of December 31, 2016. 51 Loan demand during 2018 will depend in part on economic and competitive conditions. The Company emphasized the solicitation of non-interest bearing demand deposits and money market checking deposits, which are the least sensitive to interest rates. The growth of deposit balances is subject to heightened competition, the success of the Company’s sales efforts, delivery of superior customer service and market conditions. Federal Reserve interest rate manipulation efforts have resulted in historic low short-term and long-term interest rates, which could impact deposit volumes in the future. Depending on economic conditions, interest rate levels, and a variety of other conditions, deposit growth may be used to fund loans, to reduce short-term borrowings or purchase investment securities. However, due to concerns such as uncertainty in the general economic environment, competition and political uncertainty, loan demand and levels of customer deposits are not certain. The principal cash requirements of the Company are dividends on common stock when declared. The Company is dependent upon the payment of cash dividends by the Bank to service its commitments. Shareholder dividends are expected to continue subject to the Board’s discretion and continuing evaluation of capital levels, earnings, asset quality and other factors. The Company expects that the cash dividends paid by the Bank to the Company will be sufficient to meet this payment schedule. Dividends from the Bank are subject to certain regulatory restrictions. The maturity distribution of certificates of deposit in denominations of $100,000 or more is set forth in the following table. These deposits are generally more rate sensitive than other deposits and, therefore, are more likely to be withdrawn to obtain higher yields elsewhere if available. The Bank participates in a program wherein the State of California places time deposits with the Bank at the Bank’s option. At December 31, 2017, 2016 and 2015, the Bank had $50,000,000, $50,000,000 and $50,000,000, respectively, of these State deposits.

The timing of the maturities indicated in the tables below is based on final contractual maturities. Most mortgage-backed securities return principal throughout their contractual lives. As such, the weighted average life of mortgage-backed securities based on outstanding principal balance is usually significantly shorter than the final contractual maturity indicated below. Yields on tax exempt securities are shown on a tax equivalent basis.

See Note 18 of the financial statements at Item 8 of this report for the terms. These commitments do not significantly impact operating results. As of December 31, 2017 commitments to extend credit and commitments related to the Bank’s deposit overdraft privilege product were the Bank’s only financial instruments with off-balance sheet risk. The Bank has not entered into any material contracts for financial derivative instruments such as futures, swaps, options, etc. Commitments to extend credit were $946,617,000, and $780,037,000 at December 31, 2017 and 2016, respectively, and represent 31.40% of the total loans outstanding at year-end 2017 versus 28.3% at December 31, 2016. Commitments related to the Bank’s deposit overdraft privilege product totaled $98,260,000 and $98,583,000 at December 31, 2017 and 2016, respectively. 53 Certain Contractual Obligations The following chart summarizes certain contractual obligations of the Company as of December 31, 2017: (dollars in thousands) Time deposits FHLB collateralized borrowing, fixed rate of 1.38% payable on January 2, 2018 Other collateralized borrowings, fixed rate of 0.05% payable on January 2, 2018 Junior subordinated: TriCo Trust I(1) TriCo Trust II(2) North Valley Trust II(3) North Valley Trust III(4) North Valley Trust IV(5) Operating lease obligations Deferred compensation(6) Supplemental retirement plans(6) Total contractual obligations Total $304,936 Less than one year $250,277 1-3 years $41,276 3-5 years $13,377 More than 5 years $ 6 104,729 104,729 17,437 17,437 — — — — — — 20,619 20,619 6,186 5,155 10,310 10,667 3,857 7,320 $511,835 — — — — — 3,278 839 1,107 $377,667 — — — — — 4,346 1,454 1,636 $48,712 — — — — — 2,245 867 1,161 $17,650 20,619 20,619 6,186 5,155 10,310 798 697 3,416 $67,806 (1) (2) (3) (4) (5) Junior subordinated debt, adjustable rate of three-month LIBOR plus 3.05%, callable in whole or in part by the Company on a quarterly basis beginning October 7, 2008, matures October 7, 2033.

Policies Description of Business and Basis of Presentation TriCo Bancshares (the “Company” or “we”) is a California corporation organized to act as a bank holding company for Tri Counties Bank (the “Bank”). The Company and the Bank are headquartered in Chico, California. The Bank is a California-chartered bank that is engaged in the general commercial banking business in 26 California counties. The Bank operates from 57 traditional branches, 9 in-store branches and 2 loan production offices. The Company has five capital subsidiary business trusts (collectively, the “Capital Trusts”) that issued trust preferred securities, including two organized by TriCo and three acquired with the acquisition of North Valley Bancorp. See Note 17 – Junior Subordinated Debt. The consolidated financial statements are prepared in accordance with accounting policies generally accepted in the United States of America and general practices in the banking industry. The financial statements include the accounts of the Company. All inter- company accounts and transactions have been eliminated in consolidation. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1,721,000 are accounted for under the equity method and, accordingly, are not consolidated and are included in other assets on the consolidated balance sheet. The subordinated debentures issued and guaranteed by the Company and held by the Capital Trusts are reflected as debt on the Company’s consolidated balance sheet. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Significant Group Concentration of Credit Risk The Company grants agribusiness, commercial, consumer, and residential loans to customers located throughout the northern San Joaquin Valley, the Sacramento Valley and northern mountain regions of California. The Company has a diversified loan portfolio within the business segments located in this geographical area. Management has determined that because all of the banking products and services offered by the Company are available in each branch of the Bank, all branches are located within the same economic environment and management does not allocate resources based on the performance of different lending or transaction activities, it is appropriate to aggregate the Bank branches and report them as a single operating segment. Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks, and federal funds sold. Net cash flows are reported for loan and deposit transactions and other borrowings. Investment Securities The Company classifies its debt and marketable equity securities into one of three categories: trading, available for sale or held to maturity. Trading securities are bought and held principally for the purpose of selling in the near term. Held to maturity securities are those securities which the Company has the ability and intent to hold until maturity. These securities are carried at cost adjusted for amortization of premium and accretion of discount, computed by the effective interest method over their contractual lives. All other securities not included in trading or held to maturity are classified as available for sale. Available for sale securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available for sale securities are reported as a separate component of other accumulated comprehensive income in shareholders’ equity until realized. Premiums and discounts are amortized or accreted over the life of the related investment security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned. Realized gains and losses are derived from the amortized cost of the security sold using the specific identification method. During the year ended December 31, 2017, the Company sold $24,796,000 of available for sale classified investment securities for $25,757,000 realizing a gain of $961,000. During the year ended December 31, 2016, the Company did not sell any investment securities. At December 31, 2017 and 2016, the Company did not have any securities classified as trading. The Company assesses other-than-temporary impairment (“OTTI”) based on whether it intends to sell a security or if it is likely that the Company would be required to sell the security before recovery of the amortized cost basis of the investment, which may be maturity. For debt securities, if we intend to sell the security or it is more likely than not that we will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings as an OTTI. If we do not intend to sell the security and it is not likely that we will be required to sell the security but we do not expect to recover the entire amortized cost basis of the security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a security is measured as the difference between the amortized cost basis and the present value of the cash flows expected to be collected. Projected cash flows are discounted by the original or current effective interest rate depending on the nature of the security being measured for potential OTTI. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to other comprehensive income (“OCI”). Impairment losses related to all other factors are presented as separate categories within OCI. The accretion of the amount recorded in OCI increases the carrying value of the investment and does not affect earnings. If there is an indication of additional credit losses the security is re-evaluated according to the procedures described above. No OTTI losses were recognized during the years ended December 31, 2017, 2016, and 2015. 59 Restricted Equity Securities Restricted equity securities represent the Company’s investment in the stock of the Federal Home Loan Bank of San Francisco (“FHLB”) and are carried at par value, which reasonably approximates its fair value. While technically these are considered equity securities, there is no market for the FHLB stock. Therefore, the shares are considered as restricted investment securities. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB. As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors of current investor yield requirements. Net unrealized losses are recognized through a valuation allowance by charges to noninterest income. Mortgage loans held for sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on the sale of loans that are held for sale are recognized at the time of the sale and determined by the difference between net sale proceeds and the net book value of the loans less the estimated fair value of any retained mortgage servicing rights. Loans and Allowance for Loan Losses Loans originated by the Company, i.e., not purchased or acquired in a business combination, are referred to as originated loans. Originated loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amount outstanding, net of deferred loan fees and costs. Loan origination and commitment fees and certain direct loan origination costs are deferred, and the net amount is amortized as an adjustment of the related loan’s yield over the actual life of the loan. Originated loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Originated loans are placed in nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal, or a loan becomes contractually past due by 90 days or more with respect to interest or principal and is not well secured and in the process of collection. When an originated loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of Management, the loan is estimated to be fully collectible as to both principal and interest. An allowance for loan losses for originated loans is established through a provision for loan losses charged to expense. The allowance is maintained at a level which, in Management’s judgment, is adequate to absorb probable incurred credit losses inherent in the loan portfolio as of the balance sheet date. Originated loans and deposit related overdrafts are charged against the allowance for loan losses when Management believes that the collectability of the principal is unlikely or, with respect to consumer installment loans, according to an established delinquency schedule. The allowance is an amount that Management believes will be adequate to absorb probable incurred losses inherent in existing loans, based on evaluations of the collectability, impairment and prior loss experience of loans. The evaluations take into consideration such factors as changes in the nature and size of the portfolio, overall portfolio quality, loan concentrations, specific problem loans, and current economic conditions that may affect the borrower’s ability to pay. The Company defines an originated loan as impaired when it is probable the Company will be unable to collect all amounts due according to the original contractual terms of the loan agreement. Impaired originated loans are measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate. As a practical expedient, impairment may be measured based on the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. When the measure of the impaired loan is less than the recorded investment in the loan, the impairment is recorded through a specific reserve allocation within the allowance for loan losses. In situations related to originated loans where, for economic or legal reasons related to a borrower’s financial difficulties, the Company grants a concession for other than an insignificant period of time to the borrower that the Company would not otherwise consider, the related loan is classified as a troubled debt restructuring (TDR). The Company strives to identify borrowers in financial difficulty early and work with them to modify to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where the Company grants the borrower new terms that result in the loan being classified as a TDR, the Company measures any impairment on the restructuring as noted above for impaired loans. TDR loans are classified as impaired until they are fully paid off or charged off. Loans that are in nonaccrual status at the time they become TDR loans, remain in nonaccrual status until the borrower demonstrates a sustained period of performance which the Company generally believes to be six consecutive months of payments, or equivalent. Otherwise, TDR loans are subject to the same nonaccrual and charge-off policies as noted above with respect to their restructured principal balance. 60 Credit risk is inherent in the business of lending. As a result, the Company maintains an allowance for loan losses to absorb probable incurred losses inherent in the Company’s originated loan portfolio. This is maintained through periodic charges to earnings. These charges are included in the Consolidated Statements of Income as provision for loan losses. All specifically identifiable and quantifiable losses are immediately charged off against the allowance. However, for a variety of reasons, not all losses are immediately known to the Company and, of those that are known, the full extent of the loss may not be quantifiable at that point in time. The balance of the Company’s allowance for originated loan losses is meant to be an estimate of these probable incurred losses inherent in the portfolio. The Company formally assesses the adequacy of the allowance for originated loan losses on a quarterly basis. Determination of the adequacy is based on ongoing assessments of the probable risk in the outstanding originated loan portfolio, and to a lesser extent the Company’s originated loan commitments. These assessments include the periodic re-grading of credits based on changes in their individual credit characteristics including delinquency, seasoning, recent financial performance of the borrower, economic factors, changes in the interest rate environment, growth of the portfolio as a whole or by segment, and other factors as warranted. Loans are initially graded when originated. They are re-graded as they are renewed, when there is a new loan to the same borrower, when identified facts demonstrate heightened risk of nonpayment, or if they become delinquent. Re-grading of larger problem loans occurs at least quarterly. Confirmation of the quality of the grading process is obtained by independent credit reviews conducted by consultants specifically hired for this purpose and by various bank regulatory agencies. The Company’s method for assessing the appropriateness of the allowance for originated loan losses includes specific allowances for impaired originated loans, formula allowance factors for pools of credits, and allowances for changing environmental factors (e.g., interest rates, growth, economic conditions, etc.). Allowance factors for loan pools were based on historical loss experience by product type and prior risk rating. Loans purchased or acquired in a business combination are referred to as acquired loans. Acquired loans are valued as of the acquisition date in accordance with Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) Topic 805, Business Combinations. Loans acquired with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are referred to as purchased credit impaired (PCI) loans. PCI loans are accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. Under FASB ASC Topic 805 and FASB ASC Topic 310-30, PCI loans are recorded at fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date. Fair value is defined as the present value of the future estimated principal and interest payments of the loan, with the discount rate used in the present value calculation representing the estimated effective yield of the loan. Default rates, loss severity, and prepayment speed assumptions are periodically reassessed and our estimate of future payments is adjusted accordingly. The difference between contractual future payments and estimated future payments is referred to as the nonaccretable difference. The difference between estimated future payments and the present value of the estimated future payments is referred to as the accretable yield. The accretable yield represents the amount that is expected to be recorded as interest income over the remaining life of the loan. If after acquisition, the Company determines that the estimated future cash flows of a PCI loan are expected to be more than originally estimated, an increase in the discount rate (effective yield) would be made such that the newly increased accretable yield would be recognized, on a level yield basis, over the remaining estimated life of the loan. If, thereafter, the Company determines that the estimated future cash flows of a PCI loan are expected to be less than previously estimated, an allowance for loan loss would be established through a provision for loan losses charged to expense to decrease the present value to the required level. If the estimated cash flows improve after an allowance has been established for a loan, the allowance may be partially or fully reversed depending on the improvement in the estimated cash flows. Only after the allowance has been fully reversed may the discount rate be increased. PCI loans are put on nonaccrual status when cash flows cannot be reasonably estimated. PCI loans on nonaccrual status are accounted for using the cost recovery method or cash basis method of income recognition. The Company refers to PCI loans on nonaccrual status that are accounted for using the cash basis method of income recognition as “PCI – cash basis” loans; and the Company refers to all other PCI loans as “PCI – other” loans PCI loans are charged off when evidence suggests cash flows are not recoverable. Foreclosed assets from PCI loans are recorded in foreclosed assets at fair value with the fair value at time of foreclosure representing cash flow from the loan. ASC 310-30 allows PCI loans with similar risk characteristics and acquisition time frame to be “pooled” and have their cash flows aggregated as if they were one loan. The Company elected to use the “pooled” method of ASC 310-30 for PCI – other loans in the acquisition of certain assets and liabilities of Granite Community Bank, N.A. (“Granite”) during 2010 and Citizens Bank of Northern California (“Citizens”) during 2011. Acquired loans that are not PCI loans are referred to as purchased not credit impaired (PNCI) loans. PNCI loans are accounted for under FASB ASC Topic 310-20, Receivables – Nonrefundable Fees and Other Costs, in which interest income is accrued on a level-yield basis for performing loans. For income recognition purposes, this method assumes that all contractual cash flows will be collected, and no allowance for loan losses is established at the time of acquisition. Post-acquisition date, an allowance for loan losses may need to be established for acquired loans through a provision charged to earnings for credit losses incurred subsequent to acquisition. Under ASC 310-20, the loss would be measured based on the probable shortfall in relation to the contractual note requirements, consistent with our allowance for loan loss policy for similar loans. Throughout these financial statements, and in particular in Note 4 and Note 5, when we refer to “Loans” or “Allowance for loan losses” we mean all categories of loans, including Originated, PNCI, PCI – cash basis, and PCI – other. When we are not referring to all categories of loans, we will indicate which we are referring to – Originated, PNCI, PCI – cash basis, or PCI – other. When referring to PNCI and PCI loans we use the terms “nonaccretable difference”, “accretable yield”, or “purchase discount”. Nonaccretable difference is the difference between undiscounted contractual cash flows due and undiscounted cash flows we expect to collect, or put another way, it is the undiscounted contractual cash flows we do not expect to collect. Accretable yield is the difference between undiscounted cash flows we expect to collect and the value at which we have recorded the loan on our financial statements. On the 61 date of acquisition, all purchased loans are recorded on our consolidated financial statements at estimated fair value. Purchase discount is the difference between the estimated fair value of loans on the date of acquisition and the principal amount owed by the borrower, net of charge offs, on the date of acquisition. We may also refer to “discounts to principal balance of loans owed, net of charge-offs”. Discounts to principal balance of loans owed, net of charge-offs is the difference between principal balance of loans owed, net of charge-offs, and loans as recorded on our financial statements. Discounts to principal balance of loans owed, net of charge-offs arise from purchase discounts, and equal the purchase discount on the acquisition date. Loans are also categorized as “covered” or “noncovered”. Covered loans refer to loans covered by a Federal Deposit Insurance Corporation (“FDIC”) loss sharing agreement. Noncovered loans refer to loans not covered by a FDIC loss sharing agreement. Foreclosed Assets Foreclosed assets include assets acquired through, or in lieu of, loan foreclosure. Foreclosed assets are held for sale and are initially recorded at fair value less estimated costs to sell at the date of foreclosure, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Any write-downs based on the asset’s fair value less costs to sell at the date of acquisition are charged to the allowance for loan and lease losses. Any recoveries based on the asset’s fair value less estimated costs to sell in excess of the recorded value of the loan at the date of acquisition are recorded to the allowance for loan and lease losses. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Revenue and expenses from operations and changes in the valuation allowance are included in other noninterest expense. Gain or loss on sale of foreclosed assets is included in noninterest income. Foreclosed assets that are not subject to a FDIC loss-share agreement are referred to as noncovered foreclosed assets. Foreclosed assets acquired through FDIC-assisted acquisitions that are subject to a FDIC loss-share agreement, and all assets acquired via foreclosure of covered loans are referred to as covered foreclosed assets. Covered foreclosed assets are reported exclusive of expected reimbursement cash flows from the FDIC. Foreclosed covered loan collateral is transferred into covered foreclosed assets at the loan’s carrying value, inclusive of the acquisition date fair value discount. Covered foreclosed assets are initially recorded at estimated fair value less estimated costs to sell on the acquisition date based on similar market comparable valuations less estimated selling costs. Any subsequent valuation adjustments due to declines in fair value will be charged to noninterest expense, and will be mostly offset by noninterest income representing the corresponding increase to the FDIC indemnification asset for the offsetting loss reimbursement amount. Any recoveries of previous valuation adjustments will be credited to noninterest expense with a corresponding charge to noninterest income for the portion of the recovery that is due to the FDIC. Premises and Equipment Land is carried at cost. Land improvements, buildings and equipment, including those acquired under capital lease, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization expenses are computed using the straight-line method over the shorter of the estimated useful lives of the related assets or lease terms. Asset lives range from 3-10 years for furniture and equipment and 15-40 years for land improvements and buildings. Goodwill and Other Intangible Assets Goodwill represents the excess of costs over fair value of net assets of businesses acquired. Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually. Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment. The Company has an identifiable intangible asset consisting of core deposit intangibles (CDI). CDI are amortized over their respective estimated useful lives, and reviewed for impairment. Impairment of Long-Lived Assets and Goodwill Long-lived assets, such as premises and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheet. As of December 31 of each year, goodwill is tested for impairment, and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. This determination is made at the reporting unit level. The Company may choose to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then goodwill is deemed not to be impaired. However, if the Company concludes otherwise, or if the Company elected not to first assess qualitative factors, then the Company performs the first step of a two-step 62 impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. Second, if the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. Currently, and historically, the Company is comprised of only one reporting unit that operates within the business segment it has identified as “community banking”. Goodwill was not impaired as of December 31, 2017 because the fair value of the reporting unit exceeded its carrying value. Mortgage Servicing Rights Mortgage servicing rights (MSR) represent the Company’s right to a future stream of cash flows based upon the contractual servicing fee associated with servicing mortgage loans. Our MSR arise from residential and commercial mortgage loans that we originate and sell, but retain the right to service the loans. The net gain from the retention of the servicing right is included in gain on sale of loans in noninterest income when the loan is sold. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Servicing fees are recorded in noninterest income when earned. The Company accounts for MSR at fair value. The determination of fair value of our MSR requires management judgment because they are not actively traded. The determination of fair value for MSR requires valuation processes which combine the use of discounted cash flow models and extensive analysis of current market data to arrive at an estimate of fair value. The cash flow and prepayment assumptions used in our discounted cash flow model are based on empirical data drawn from the historical performance of our MSR, which we believe are consistent with assumptions used by market participants valuing similar MSR, and from data obtained on the performance of similar MSR. The key assumptions used in the valuation of MSR include mortgage prepayment speeds and the discount rate. These variables can, and generally will, change from quarter to quarter as market conditions and projected interest rates change. The key risks inherent with MSR are prepayment speed and changes in interest rates. The Company uses an independent third party to determine fair value of MSR. Indemnification Asset/Liability The Company accounts for amounts receivable or payable under its loss-share agreements entered into with the FDIC in connection with its purchase and assumption of certain assets and liabilities of Granite as indemnification assets in accordance with FASB ASC Topic 805, Business Combinations. FDIC indemnification assets are initially recorded at fair value, based on the discounted value of expected future cash flows under the loss-share agreements. The difference between the fair value and the undiscounted cash flows the Company expects to collect from or pay to the FDIC will be accreted into noninterest income over the life of the FDIC indemnification asset. FDIC indemnification assets are reviewed quarterly and adjusted for any changes in expected cash flows based on recent performance and expectations for future performance of the covered portfolios. These adjustments are measured on the same basis as the related covered loans and covered other real estate owned. Any increases in cash flow of the covered assets over those expected will reduce the FDIC indemnification asset and any decreases in cash flow of the covered assets under those expected will increase the FDIC indemnification asset. Increases and decreases to the FDIC indemnification asset are recorded as adjustments to noninterest income. Reserve for Unfunded Commitments The reserve for unfunded commitments is established through a provision for losses – unfunded commitments charged to noninterest expense. The reserve for unfunded commitments is an amount that Management believes will be adequate to absorb probable losses inherent in existing commitments, including unused portions of revolving lines of credit and other loans, standby letters of credit, and unused deposit account overdraft privileges. The reserve for unfunded commitments is based on evaluations of the collectability, and prior loss experience of unfunded commitments. The evaluations take into consideration such factors as changes in the nature and size of the loan portfolio, overall loan portfolio quality, loan concentrations, specific problem loans and related unfunded commitments, and current economic conditions that may affect the borrower’s or depositor’s ability to pay. Low Income Housing Tax Credits The Company accounts for low income housing tax credits and the related qualified affordable housing projects using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). Upon entering into a qualified affordable housing project, the Company records, in other liabilities, the entire amount that it has agreed to invest in the project, and an equal amount, in other assets, representing its investment in the project. As the Company disburses cash to satisfy its investment obligation, other liabilities are reduced. Over time, as the tax credits and other tax benefits of the project are realized by the Company, the investment recorded in other assets is reduced using the proportional amortization method. Income Taxes The Company’s accounting for income taxes is based on an asset and liability approach. The Company recognizes the amount of taxes payable or refundable for the current year, and deferred tax assets and liabilities for the future tax consequences that have been recognized in its financial statements or tax returns. The measurement of tax assets and liabilities is based on the provisions of enacted tax laws. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. Interest and/or penalties related to income taxes are reported as a component of noninterest income. 63 Off-Balance Sheet Credit Related Financial Instruments In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. Geographical Descriptions For the purpose of describing the geographical location of the Company’s loans, the Company has defined northern California as that area of California north of, and including, Stockton; central California as that area of the state south of Stockton, to and including, Bakersfield; and southern California as that area of the state south of Bakersfield. Reclassifications During the three months ended September 30, 2017, the Company changed its classification of 1st lien and 2nd lien non-owner occupied 1-4 residential real estate mortgage loans from commercial real estate mortgage loans to residential real estate mortgage loans and consumer home equity loans, respectively. This change in loan category classification was made to better align the Company’s financial reporting classifications with regulatory reporting classifications, and to properly classify these loans for regulatory risk-based capital ratio calculations. As a result of these reclassifications, at September 30, 2017, loans with balances of $60,957,000, and $5,620,000, that would have been classified as commercial real estate mortgage loans prior to this change, were classified as residential real estate mortgage loans, and consumer home equity loans, respectively; and the Company’s, and the Bank’s, Total risk based capital ratios, Tier 1 capital ratios, and Tier 1 common equity ratios were all recalculated to be 0.10%-0.20% higher than they would have been prior to this change. Certain amounts reported in previous consolidated financial statements have been reclassified and recalculated to conform to the presentation in this report. These reclassifications did not affect previously reported net income, total loans or total shareholders’ equity. Recent Accounting Pronouncements FASB Accounting Standards Update (ASU) No.2014-09, Revenue from Contracts with Customers (Topic 606): ASU 2014-09 is intended to clarify the principles for recognizing revenue, and to develop common revenue standards and disclosure requirements that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosures; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. The guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required with regard to contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein, with early adoption permitted for reporting periods beginning after December 15, 2016. ASU 2014-09 does not apply to revenue associated with financial instruments such as loans and investments, which are accounted for under other provisions of GAAP. The Company adopted ASU 2014-09 on January 1, 2018 utilizing the modified retrospective approach, and the adoption of ASU 2014-09 did not have a significant impact on the Company’s consolidated financial statements. FASB issued Accounting Standard Update (ASU) No. 2016-02, Leases (Topic 842). ASU 2016-2, among other things, requires lessees to recognize most leases on-balance sheet, increasing reported assets and liabilities. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 will be effective for the Company on January 1, 2019, utilizing the modified retrospective transition approach. The Company is currently evaluating the provisions of ASU No. 2016-02 and has determined that the adoption of this standard will result in an increase in assets to recognize the present value of the lease obligations with a corresponding increase in liabilities; however, the Company does not expect this to have a material impact on the Company’s results of operations or cash flows. FASB issued Accounting Standard Update (ASU) No. 2016-09, Compensation – Stock Compensation (Topic 718). ASU 2016-09, among other things, requires: (i) that all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) should be recognized as income tax expense or benefit in the income statement, (ii) the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur, (iii) an entity also should recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period, (iv) excess tax benefits should be classified along with other income tax cash flows as an operating activity, (v) an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur, (vi) the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions, and (vii) cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity. ASU 2016-09 was effective for the Company on January 1, 2017 and due to options exercised and restricted stock units released during the year ended December, 2017, the Company recognized excess tax benefits totaling $906,000 during the year ended December 31, 2017. FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326). ASU 2016-13 is the final guidance on the new current expected credit loss (‘‘CECL’’) model. ASU 2016-13, among other things, requires the incurred loss impairment methodology in current GAAP be replaced with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate future credit loss estimates. As CECL encompasses all financial assets carried at amortized cost, the requirement that reserves be established based on an organization’s reasonable and supportable estimate of expected credit losses extends to held to maturity (‘‘HTM’’) debt securities. ASU 2016-13 amends the accounting for credit losses on available-for-sale securities (‘‘AFS’’), whereby credit losses will be presented as an allowance as opposed to a write-down. In addition, CECL will modify the accounting for purchased loans with credit deterioration since origination, so that reserves are established at the date of acquisition for purchased loans. Lastly, ASU 2016-13 requires enhanced disclosures on the significant estimates and judgments used to estimate credit losses, as well as on 64 the credit quality and underwriting standards of an organization’s portfolio. These disclosures require organizations to present the currently required credit quality disclosures disaggregated by the year of origination or vintage. ASU 2016-13 allows for a modified retrospective approach with a cumulative effect adjustment to the balance sheet upon adoption (charge to retained earnings instead of the income statement). ASU 2016-13 will be effective for the Company on January 1, 2020, and early adoption is permitted. While the Company is currently evaluating the provisions of ASU 2016-13 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements, it has taken steps to prepare for the implementation when it becomes effective, such as forming an internal task force, gathering pertinent data, consulting with outside professionals, and evaluating its current IT systems. Management expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the first reporting period in which the new standard is effective, but cannot yet estimate the magnitude of the one-time adjustment or the overall impact of the new guidance on the Company’s financial position, results of operations or cash flows. FASB issued ASU No. 2016-18, Statement of Cash Flows - Restricted Cash (Topic 230). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 was effective for the Company on January 1, 2018 and did not have a significant impact on the Company’s consolidated financial statements. FASB issued ASU No. 2017-01, Business Combinations - Clarifying the Definition of a Business (Topic 805). ASU 2017-01 clarifies the definition and provides a more robust framework to use in determining when a set of assets and activities constitutes a business. ASU 2017-01 is intended to provide guidance when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 was effective for the Company on January 1, 2018 and did not have a significant impact on the Company’s consolidated financial statements. FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment (Topic 350). ASU 2017-04 eliminates step two of the goodwill impairment test (the hypothetical purchase price allocation used to determine the implied fair value of goodwill) when step one (determining if the carrying value of a reporting unit exceeds its fair value) is failed. Instead, entities simply will compare the fair value of a reporting unit to its carrying amount and record goodwill impairment for the amount by which the reporting unit’s carrying amount exceeds its fair value. ASU 2017-04 will be effective for the Company on January 1, 2020 and is not expected to have a significant impact on the Company’s consolidated financial statements. FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715). ASU 2017-07 requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component. ASU 2017-07 was effective for the Company on January 1, 2018 and did not have a significant impact on the Company’s consolidated financial statements. FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Topic 310). ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 will be effective for the Company on January 1, 2019, and is not expected to have a significant impact on the Company’s consolidated financial statements. FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the award’s fair value, (ii) the award’s vesting conditions and (iii) the award’s classification as an equity or liability instrument. ASU 2017-09 was effective for the Company on January 1, 2018 and did not have a significant impact on the Company’s consolidated financial statements. FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220). ASU 2018-02 allows, but does not require, entities to reclassify certain income tax effects in accumulated other comprehensive income (AOCI) to retained earnings that resulted from the Tax Cuts and Jobs Act (Tax Act) that was enacted on December 22, 2017. The Tax Act included a reduction to the Federal corporate income tax rate from 35 percent to 21 percent effective January 1, 2018. The amount of the reclassification would be the difference between the income tax effects in AOCI calculated using the historical Federal corporate income tax rate of 35 percent and the income tax effects in AOCI calculated using the newly enacted 21 percent Federal corporate income tax rate. The amendments in ASU 2018-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2018-02 on January 1, 2018, and elected to reclassify certain income tax effects in AOCI to retained earnings. This change in accounting principle was accounted for as a cumulative-effect adjustment to the balance sheet resulting in a $1,093,000 increase to retained earnings and a corresponding decrease to AOCI on January 1, 2018. 65 Note 2 – Business Combinations Proposed Merger with FNB Bancorp On December 11, 2017, the Company and FNB Bancorp, a California corporation (“FNBB”), entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) pursuant to which FNBB will be merged with and into the Company, with the Company as the surviving corporation (the “Merger”). Management expects the acquisition to close in the second quarter of 2018, subject to the satisfaction of customary closing conditions, including regulatory and shareholder approvals. The Merger Agreement provides that immediately after the Merger, FNBB’s bank subsidiary, First National Bank of Northern California (“First National Bank”), will merge with and into the Company’s bank subsidiary, Tri Counties Bank, with Tri Counties Bank as the surviving bank (the “Bank Merger”). The Merger and Bank Merger are collectively referred to as the “Proposed Transaction.” The Merger Agreement provides that each share of FNBB common stock issued and outstanding immediately prior to the effective time of the Merger will be canceled and converted into the right to receive 0.98 shares of the Company’s common stock (the “Exchange Ratio”), with cash paid in lieu of fractional shares of the Company’s common stock. Based on the closing price of the Company’s common stock of $41.64 on December 8, 2017, the consideration value was $40.81 per share of FNBB common stock or approximately $315.3 million in aggregate. The value of the merger consideration will fluctuate until closing based on the value of the Company’s stock and subject to a trading collar in certain circumstances. Upon consummation of the Merger, the shareholders of FNBB will own approximately 24% of the combined company. The Merger Agreement includes a trading collar that could result in termination of the Merger Agreement or a change to the Exchange Ratio. First, The Company can elect to terminate the Merger Agreement if both (i) the average share price of the Company’s common stock for the 20 day period up to and including the fifth day prior to the closing date (the “Average Closing Share Price”) is greater than $49.78, which equals 120% of the average share price of the Company’s Stock for the 20 trading-day period up to and including December 8, 2017, which was $41.48 (the “Initial Price”) and (ii) the Company’s common stock outperforms the KBW Regional Banking Index by more than 20%, unless FNBB agrees that the Exchange Ratio will be reduced and fewer shares of the Company’s common stock will be issued to FNBB shareholders on a per share basis. Conversely, FNBB can terminate the Merger Agreement if both (i) the Average Closing Share Price is less than $33.18, which is equivalent to 80% of the Initial Price, and (ii) the Company’s common stock underperforms the KBW Regional Banking Index by more than 20%, unless the Company agrees that the Exchange Ratio will be increased and more shares of the Company common stock will be issued to FNBB shareholders on a per share basis. Upon consummation of the Merger, each outstanding and unexercised option to acquire shares of FNBB common stock held by FNBB’s employees and directors will be canceled and, in exchange, the holder of the option will be entitled to receive, whether or not the option is fully vested, a lump sum cash payment equal to the product of (1) the number of shares of FNBB common stock remaining under the option multiplied by (2) the Exchange Ratio multiplied by (3) the amount, if any, by which the Average Closing Share Price exceeds the exercise price of the option. The consummation of the Merger is subject to a number of conditions, which include: (i) the approval of the Merger Agreement by FNBB’s shareholders and the approval of the Merger Agreement and the issuance of shares of the Company common stock by the Company’s shareholders; (ii) as of the closing of the Merger, FNBB shall have tangible common equity of not less than $119.0 million, subject to credit for certain merger-related expenses and certain assumptions and adjustments that are set forth in the Merger Agreement; (iii) the receipt of all necessary regulatory approvals for the Proposed Transaction, without the imposition of conditions or requirements that the Company’s Board of Directors reasonably determines in good faith would, individually or in the aggregate, materially reduce the economic benefits of the Proposed Transaction; (iv) the absence of any regulation, judgment, decree, injunction or other order of a governmental authority which prohibits the consummation of the Proposed Transaction or which prohibits or makes illegal the consummation of the Proposed Transaction; (v) the effective registration of the shares of the Company’s Common Stock to be issued to FNBB’s shareholders with the Securities and Exchange Commission (the “SEC”) and the approval of such shares for listing on the Nasdaq Global Select Market; (vi) all representations and warranties made by the Company and FNBB in the Merger Agreement must remain true and correct, except for certain inaccuracies that would not have, or would not reasonably be expected to have, a material adverse effect; and (vii) the Company and FNBB must have performed their respective obligations under the Merger Agreement in all material respects. 66 Note 2 – Business Combinations (continued) Acquisition of Three Bank Branches and Associated Deposits On March 18, 2016, the Bank completed its acquisition of three branch banking offices from Bank of America originally announced October 28, 2015. The acquired branches are located in Arcata, Eureka and Fortuna in Humboldt County on the North Coast of California, and have significant overlap compared to the Company’s then-existing Northern California customer base and branch locations. As a result, these branch acquisitions create potential cost savings and future growth potential. With the levels of capital at the time, the acquisitions fit well into the Company’s growth strategy. Also on March 18, 2016, the electronic customer service and other data processing systems of the acquired branches were converted into the Bank’s systems, and the effect of revenue and expenses from the operations of the acquired branches are included in the results of the Company. The Bank paid a premium of $3,204,000 for deposit relationships with balances of $161,231,000 and loans with balances of $289,000, and received cash of $159,520,000 from Bank of America. The assets acquired and liabilities assumed in the acquisition of these branches were accounted for in accordance with ASC 805 “Business Combinations,” using the acquisition method of accounting and were recorded at their estimated fair values on the March 18, 2016 acquisition date, and the results of operations of the acquired branches are included in the Company’s consolidated statements of income since that date. The excess of the fair value of consideration transferred over total identifiable net assets was recorded as goodwill. The goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company and the acquired branches. $849,000 of the goodwill is deductible for income tax purposes because the acquisition was accounted for as a purchase of assets and assumption of liabilities for tax purposes. The following table discloses the calculation of the fair value of consideration transferred, the total identifiable net assets acquired and the resulting goodwill relating to the acquisition of three branch banking offices and certain deposits from Bank of America on March 18, 2016: (in thousands) Fair value of consideration transferred: Cash consideration Total fair value of consideration transferred Asset acquired: Cash and cash equivalents Loans Premises and equipment Core deposit intangible Other assets Total assets acquired Liabilities assumed: Deposits Total liabilities assumed Total net assets acquired Goodwill recognized March 18, 2016 $ 3,204 3,204 159,520 289 1,590 2,046 141 163,586 161,231 161,231 2,355 849 $ A summary of the cash paid and estimated fair value adjustments resulting in the goodwill recorded in the acquisition of three branch banking offices and certain deposits from Bank of America on March 18, 2016 are presented below: (in thousands) Cash paid Cost basis net assets acquired Fair value adjustments: Loans Premises and Equipment Core deposit intangible Goodwill March 18, 2016 3,204 $ — — (309) (2,046) 849 $ As part of the acquisition of three branch banking offices from Bank of America, the Company performed a valuation of premises and equipment acquired. This valuation resulted in a $309,000 increase in the net book value of the land and buildings acquired, and was based on current appraisals of such land and buildings. The Company recognized a core deposit intangible of $2,046,000 related to the acquisition of the core deposits. The recorded core deposit intangibles represented approximately 1.50% of the core deposits acquired and will be amortized over their estimated useful lives of 7 years. A valuation of the time deposits acquired was also performed as of the acquisition date. Time deposits were split into similar pools based on size, type of time deposits, and maturity. A discounted cash flow analysis was performed on the pools based on current market rates currently paid on similar time deposits. The valuation resulted in no material fair value discount or premium, and none was recorded. 67 Note 3 – Investment Securities The amortized cost and estimated fair values of investments in debt and equity securities are summarized in the following tables: Securities Available for Sale Obligations of U.S. government corporations and agencies Obligations of states and political subdivisions Marketable equity securities Total securities available for sale Securities Held to Maturity Obligations of U.S. government corporations and agencies Obligations of states and political subdivisions Total securities held to maturity Securities Available for Sale Obligations of U.S. government corporations and agencies Obligations of states and political subdivisions Marketable equity securities Total securities available for sale Securities Held to Maturity Obligations of U.S. government corporations and agencies Obligations of states and political subdivisions Total securities held to maturity December 31, 2017 Gross Unrealized Losses Gross Unrealized Gains (in thousands) Estimated Fair Value $ 695 1,888 — $ 2,583 $ 5,101 146 $ 5,247 $ (5,601) (329) (62) $ (5,992) $604,789 123,156 2,938 $730,883 $ (1,889) (37) $ (1,926) $503,483 14,682 $518,165 December 31, 2016 Gross Unrealized Losses Gross Unrealized Gains (in thousands) Estimated Fair Value $ 1,949 267 — $ 2,216 $ 5,001 56 $ 5,057 $ (6,628) (4,396) (62) $(11,086) $429,678 117,617 2,938 $550,233 $ (4,199) (191) $ (4,390) $588,784 14,419 $603,203 Amortized Cost $609,695 121,597 3,000 $734,292 $500,271 14,573 $514,844 Amortized Cost $434,357 121,746 3,000 $559,103 $587,982 14,554 $602,536 During 2017 investment securities with cost basis of $24,796,000 were sold for $25,757,000, resulting in a gain of $961,000 on sale. No investment securities were sold during 2016. Investment securities totaling $2,000 were sold in 2015 resulting in no gain or loss on sale. Investment securities with an aggregate carrying value of $285,596,000 and $292,737,000 at December 31, 2017 and 2016, respectively, were pledged as collateral for specific borrowings, lines of credit and local agency deposits. The amortized cost and estimated fair value of debt securities at December 31, 2017 by contractual maturity are shown below. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. At December 31, 2017, obligations of U.S. government corporations and agencies with a cost basis totaling $1,109,966,000 consist almost entirely of residential real estate mortgage-backed securities whose contractual maturity, or principal repayment, will follow the repayment of the underlying mortgages. For purposes of the following table, the entire outstanding balance of these mortgage-backed securities issued by U.S. government corporations and agencies is categorized based on final maturity date. At December 31, 2017, the Company estimates the average remaining life of these mortgage-backed securities issued by U.S. government corporations and agencies to be approximately 5.9 years. Average remaining life is defined as the time span after which the principal balance has been reduced by half.

The contractual cash flows of these securities are guaranteed by U.S. Government Sponsored Entities (principally Fannie Mae and Freddie Mac). It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell and more likely than not will not be required to sell, these investments are not considered other-than-temporarily impaired. At December 31, 2017, 69 debt securities representing obligations of U.S. government corporations and agencies had unrealized losses with aggregate depreciation of 1.16% from the Company’s amortized cost basis. Obligations of states and political subdivisions: The unrealized losses on investments in obligations of states and political subdivisions were caused by increases in required yields by investors in these types of securities. It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell and more likely than not will not be required to sell, these investments are not considered other-than-temporarily impaired. At December 31, 2017, 29 debt securities representing obligations of states and political subdivisions had unrealized losses with aggregate depreciation of 1.38% from the Company’s amortized cost basis. Marketable equity securities: At December 31, 2017, marketable equity securities had unrealized losses representing aggregate depreciation of 2.07% from the Company’s amortized cost basis. Because the Company has the ability to hold these equity investment securities and management does not intend to sell and more likely than not will not be required to sell these securities prior to the recovery of value, management does not believe these securities to be other than temporarily impaired. 69 Note 4 – Loans A summary of loan balances follows (in thousands): Mortgage loans on real estate: Residential 1-4 family Commercial Total mortgage loan on real estate Consumer: Home equity lines of credit Home equity loans Other Total consumer loans Commercial Construction: Residential Commercial Total construction Total loans, net of deferred loan fees and discounts Total principal balance of loans owed, net of charge-offs Unamortized net deferred loan fees Discounts to principal balance of loans owed, net of charge-offs Total loans, net of unamortized deferred loan fees and discounts Noncovered loans Covered loans Total loans, net of unamortized deferred loan fees and discounts Allowance for loan losses 70 Originated PNCI December 31, 2017 PCI - Cash basis PCI - Other Total $ 320,522 1,690,510 2,011,032 $ 63,519 215,823 279,342 — — — $ 1,385 8,563 9,948 $ 385,426 1,914,896 2,300,322 269,942 39,848 22,859 332,649 209,437 67,920 69,364 137,284 $2,690,402 $2,699,053 (8,651) — $2,690,402 $2,690,402 — $2,690,402 $ (29,122) $ 16,248 2,698 2,251 21,197 8,391 2,069 — — 2,069 — 429 485 45 959 2,584 288,688 43,031 25,155 356,874 220,412 10 263 273 $309,203 $316,238 — (7,035) $309,203 $309,203 — $309,203 — — — $ 2,069 $ 5,863 — (3,794) $ 2,069 $ 2,069 — $ 2,069 — — — $13,491 $17,318 — (3,827) $13,491 $13,491 — $13,491 67,930 69,627 137,557 $3,015,165 $3,038,472 (8,651) (14,656) $3,015,165 $3,015,165 — $3,015,165 (929) $ (17) $ (255) $ (30,323) Note 4 – Loans (continued) A summary of loan balances follows (in thousands): Mortgage loans on real estate: Residential 1-4 family Commercial Total mortgage loan on real estate Consumer: Home equity lines of credit Home equity loans Other Total consumer loans Commercial Construction: Residential Commercial Total construction Total loans, net of deferred loan fees and discounts Total principal balance of loans owed, net of charge-offs Unamortized net deferred loan fees Discounts to principal balance of loans owed, net of charge-offs Total loans, net of unamortized deferred loan fees and discounts Noncovered loans Covered loans Total loans, net of unamortized deferred loan fees and discounts Allowance for loan losses 263,590 40,736 28,167 332,493 200,735 54,613 58,119 112,732 $2,356,327 $2,363,243 Originated PNCI December 31, 2016 PCI - Cash basis PCI - Other Total $ 284,539 1,425,828 1,710,367 $ 82,335 246,491 328,826 — — — $ 1,469 12,802 14,271 $ 368,343 1,685,121 2,053,464 21,765 3,764 2,534 28,063 12,321 2,983 — — 2,983 — 1,377 1,682 65 3,124 3,991 289,715 46,182 30,766 366,663 217,047 141 8,871 9,012 $378,222 $388,139 — (9,917) (6,916) — $2,356,327 $2,356,327 — $2,356,327 $ (28,141) $ (1,665) $ $378,222 $378,222 — $378,222 — — — $ 2,983 $ 8,280 — (5,297) $ 2,983 $ 2,983 — $ 2,983 675 — 675 $22,061 $25,650 — (3,589) $22,061 $18,885 3,176 $22,061 55,429 66,990 122,419 $2,759,593 $2,785,312 (6,916) (18,803) $2,759,593 $2,756,417 3,176 $2,759,593 (17) $ (2,680) $ (32,503) The following is a summary of the change in accretable yield for PCI – other loans during the periods indicated (in thousands): Change in accretable yield: Balance at beginning of period Accretion to interest income Reclassification (to) from nonaccretable difference Balance at end of period 71 Year ended December 31, 2017 2016 $ 10,348 (2,809) (3,277) $ 4,262 $ 13,255 (4,011) 1,104 $ 10,348 Note 5 – Allowance for Loan Losses The following tables summarize the activity in the allowance for loan losses, and ending balance of loans, net of unearned fees for the periods indicated.

The Company utilizes a risk grading system to assign a risk grade to each of its loans. Loans are graded on a scale ranging from Pass to Loss. A description of the general characteristics of the risk grades is as follows: • • • Pass – This grade represents loans ranging from acceptable to very little or no credit risk. These loans typically meet most if not all policy standards in regard to: loan amount as a percentage of collateral value, debt service coverage, profitability, leverage, and working capital. Special Mention – This grade represents “Other Assets Especially Mentioned” in accordance with regulatory guidelines and includes loans that display some potential weaknesses which, if left unaddressed, may result in deterioration of the repayment prospects for the asset or may inadequately protect the Company’s position in the future. These loans warrant more than normal supervision and attention. Substandard – This grade represents “Substandard” loans in accordance with regulatory guidelines. Loans within this rating typically exhibit weaknesses that are well defined to the point that repayment is jeopardized. Loss potential is, however, not necessarily evident. The underlying collateral supporting the credit appears to have sufficient value to protect the Company from loss of principal and accrued interest, or the loan has been written down to the point where this is true. There is a definite need for a well defined workout/rehabilitation program. • Doubtful – This grade represents “Doubtful” loans in accordance with regulatory guidelines. An asset classified as Doubtful has all the weaknesses inherent in a loan classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral, and financing plans. • Loss – This grade represents “Loss” loans in accordance with regulatory guidelines. A loan classified as Loss is considered uncollectible and of such little value that its continuance as a bankable asset is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the loan, even though some recovery may be affected in the future. The portion of the loan that is graded loss should be charged off no later than the end of the quarter in which the loss is identified. 73 Note 5 – Allowance for Loan Losses (continued) The following tables present ending loan balances by loan category and risk grade for the periods indicated: (in thousands) Originated loans: Pass Special mention Substandard Loss Total originated PNCI loans: Pass Special mention Substandard Loss Total PNCI PCI loans Total loans (in thousands) Originated loans: Pass Special mention Substandard Loss Total originated PNCI loans: Pass Special mention Substandard Loss Total PNCI PCI loans Total loans RE Mortgage Home Equity Resid.

Typically non-payment is due to loss of job and will follow general economic trends in the marketplace driven primarily by rises in the unemployment rate. Loss of collateral value can be due to market demand shifts, damage to collateral itself or a combination of the two. Problem consumer loans are generally identified by payment history of the borrower (delinquency). The Bank manages its consumer loan portfolios by monitoring delinquency and contacting borrowers to encourage repayment, suggest modifications if appropriate, and, when continued scheduled payments become unrealistic, initiate repossession or foreclosure through appropriate channels. Collateral values may be determined by appraisals obtained through Bank approved, licensed appraisers, qualified independent third parties, public value information (blue book values for autos), sales invoices, or other appropriate means. Appropriate valuations are obtained at initiation of the credit and periodically (every 3-12 months depending on collateral type) once repayment is questionable and the loan has been classified. Commercial real estate loans generally fall into two categories, owner-occupied and non-owner occupied. Loans secured by owner occupied real estate are primarily susceptible to changes in the business conditions of the related business. This may be driven by, among other things, industry changes, geographic business changes, changes in the individual fortunes of the business owner, and general economic conditions and changes in business cycles. These same risks apply to commercial loans whether secured by equipment or other personal property or unsecured. Losses on loans secured by owner occupied real estate, equipment, or other personal property generally are dictated by the value of underlying collateral at the time of default and liquidation of the collateral. When default is driven by issues related specifically to the business owner, collateral values tend to provide better repayment support and may result in little or no loss. Alternatively, when default is driven by more general economic conditions, underlying collateral generally has devalued more and results in larger losses due to default. Loans secured by non-owner occupied real estate are primarily susceptible to risks associated with swings in occupancy or vacancy and related shifts in lease rates, rental rates or room rates. Most often these shifts are a result of changes in general economic or market conditions or overbuilding and resultant over-supply. Losses are dependent on value of underlying collateral at the time of default. Values are generally driven by these same factors and influenced by interest rates and required rates of return as well as changes in occupancy costs. 74 Note 5 – Allowance for Loan Losses (continued) Construction loans, whether owner occupied or non-owner occupied commercial real estate loans or residential development loans, are not only susceptible to the related risks described above but the added risks of construction itself including cost over-runs, mismanagement of the project, or lack of demand or market changes experienced at time of completion. Again, losses are primarily related to underlying collateral value and changes therein as described above. Problem C&I loans are generally identified by periodic review of financial information which may include financial statements, tax returns, rent rolls and payment history of the borrower (delinquency). Based on this information the Bank may decide to take any of several courses of action including demand for repayment, additional collateral or guarantors, and, when repayment becomes unlikely through borrower’s income and cash flow, repossession or foreclosure of the underlying collateral. Collateral values may be determined by appraisals obtained through Bank approved, licensed appraisers, qualified independent third parties, public value information (blue book values for autos), sales invoices, or other appropriate means. Appropriate valuations are obtained at initiation of the credit and periodically (every 3-12 months depending on collateral type) once repayment is questionable and the loan has been classified. Once a loan becomes delinquent and repayment becomes questionable, a Bank collection officer will address collateral shortfalls with the borrower and attempt to obtain additional collateral. If this is not forthcoming and payment in full is unlikely, the Bank will estimate its probable loss, using a recent valuation as appropriate to the underlying collateral less estimated costs of sale, and charge the loan down to the estimated net realizable amount. Depending on the length of time until ultimate collection, the Bank may revalue the underlying collateral and take additional charge-offs as warranted. Revaluations may occur as often as every 3-12 months depending on the underlying collateral and volatility of values. Final charge-offs or recoveries are taken when collateral is liquidated and actual loss is known. Unpaid balances on loans after or during collection and liquidation may also be pursued through lawsuit and attachment of wages or judgment liens on borrower’s other assets.

If the loan is determined to be collateral dependent, any additional amount of impairment will be calculated based on the difference between estimated collectible value and the current carrying balance of the loan. This difference could result in an increased provision and is typically charged off. If the asset is determined not to be collateral dependent, the impairment is measured on the net present value difference between the expected cash flows of the restructured loan and the cash flows which would have been received under the original terms. The effect of this could result in a requirement for additional provision to the reserve. The effect of these required provisions for the period are indicated above. Typically if a TDR defaults during the period, the loan is then considered collateral dependent and, if it was not already considered collateral dependent, an appropriate provision will be reserved or charge will be taken. The additional provisions required resulting from default of previously modified TDR’s are noted above.

These life insurance policies are recorded on the Company’s financial statements at their reported cash (surrender) values. As a result of current tax law and the nature of these policies, the Bank records any increase in cash value of these policies as nontaxable noninterest income. If the Bank decided to surrender any of the policies prior to the death of the insured, such surrender may result in a tax expense related to the life-to-date cumulative increase in cash value of the policy. If the Bank retains such policies until the death of the insured, the Bank would receive nontaxable proceeds from the insurance company equal to the death benefit of the policies. The Bank has entered into Joint Beneficiary Agreements (JBAs) with certain of the insured that for certain of the policies provide some level of sharing of the death benefit, less the cash surrender value, among the Bank and the beneficiaries of the insured upon the receipt of death benefits. See Note 15 of these consolidated financial statements for additional information on JBAs.

The changes in fair value of MSRs during 2016 were primarily due to changes in principal balances, changes in mortgage prepayment speeds, and changes in investor required rate of return, or discount rate, of the MSRs. The changes in fair value of MSRs that occurred during 2015 were primarily due to changes in principal balances and changes in estimate life of the MSRs.

The indemnification portion of the Company’s agreement with the FDIC related to the Company’s acquisition of certain residential real estate loans of Granite in May 2010 was set to expire in May 2018. The agreement specified that recoveries of losses that are claimed by the Company and indemnified by the FDIC under the agreement that are recovered by the Company through May 2020 are to be shared with the FDIC in the same proportion as they were indemnified by the FDIC. In addition, the agreement specified that at the end of the agreement in May 2020, to the extent that total claimed losses plus servicing expenses, net of recoveries, claimed under the agreement over the entire ten year period of the agreement did not meet a certain threshold, the Company would have been required to pay to the FDIC a “true up” amount equal to fifty percent of the difference of the threshold and actual claimed losses plus servicing expenses, net of recoveries. On May 9, 2017, the Company and the FDIC terminated their loss sharing agreements. As part of the termination agreement, the Company paid the FDIC $184,000, and recorded a $712,000 gain representing the difference between the Company’s payment to the FDIC and the recorded payable balance on May 9, 2017. 81 Note 12 – Other Assets Other assets were comprised of (in thousands): Deferred tax asset, net (Note 22) Prepaid expense Software Advanced compensation Capital Trusts Investment in Low Housing Tax Credit Funds Life insurance proceeds receivable Prepaid Taxes Premises held for sale Miscellaneous other assets Total other assets Note 13 – Deposits A summary of the balances of deposits follows (in thousands): Noninterest-bearing demand Interest-bearing demand Savings Time certificates, over $250,000 Other time certificates Total deposits As of December 31, 2016 2017 $36,199 $21,697 3,045 4,111 2,039 1,126 249 16 1,702 1,706 18,465 16,854 2,120 2,242 6,460 4,754 2,896 — 1,568 2,545 $74,743 $55,051 December 31, 2017 $1,368,218 971,459 1,364,518 73,596 231,340 $4,009,131 2016 $1,275,745 887,625 1,397,036 75,184 259,970 $3,895,560 Certificate of deposit balances of $50,000,000 from the State of California were included in time certificates over $250,000 at December 31, 2017 and 2016.

Overdrawn deposit balances of $1,366,000 and $1,191,000 were classified as consumer loans at December 31, 2017 and 2016, respectively. At December 31, 2017, the scheduled maturities of time deposits were as follows (in thousands): 2018 2019 2020 2021 2020 Thereafter Total Scheduled Maturities $250,277 23,577 17,699 8,887 4,496 $304,936 Note 14 – Reserve for Unfunded Commitments The following tables summarize the activity in reserve for unfunded commitments for the periods indicated (dollars in thousands): Balance at beginning of period Provision for losses – Unfunded commitments Balance at end of period 82 Years ended December 31, 2016 $2,475 244 $2,719 2017 $2,719 445 $3,164 2015 $2,145 330 $2,475 Note 15 – Other Liabilities Other liabilities were comprised of (in thousands): Deferred compensation Pension liability Joint beneficiary agreements Low income housing tax credit fund commitments Accrued salaries and benefits expense Loan escrow and servicing payable Deferred revenue Litigation contingency Miscellaneous other liabilities Total other liabilities Note 16 – Other Borrowings A summary of the balances of other borrowings follows: FHLB collateralized borrowing, fixed rate, as of December 31, 2017 of 1.38%, payable on January 2, 2018 Other collateralized borrowings, fixed rate, as of December 31, 2017 of 0.05%, payable on January 2, 2018 Total other borrowings December 31, 2017 $ 6,605 28,472 3,365 8,554 6,619 1,958 1,228 1,450 5,007 $63,258 2016 $ 6,525 26,645 3,007 15,176 5,704 2,146 726 1,450 5,985 $67,364 December 31, 2017 2016 (in thousands) $104,729 — 17,437 $122,166 $17,493 $17,493 The Company did not enter into any other borrowings or repurchase agreements during 2017 or 2016. The Company maintains a collateralized line of credit with the FHLB. Based on the FHLB stock requirements at December 31, 2017, this line provided for maximum borrowings of $1,365,325,000 of which $104,729,000 was outstanding, leaving $1,260,596,000 available. As of December 31, 2017, the Company had designated investment securities with a fair value of $67,325,000 and loans totaling $1,992,980,000 as potential collateral under this collateralized line of credit with the FHLB. The Company had $17,437,000 and $17,493,000 of other collateralized borrowings at December 31, 2017 and 2016, respectively. Other collateralized borrowings are generally overnight maturity borrowings from non-financial institutions that are collateralized by securities owned by the Company. As of December 31, 2017, the Company has pledged as collateral and sold under agreements to repurchase investment securities with fair value of $33,531,000 under these other collateralized borrowings. The Company maintains a collateralized line of credit with the Federal Reserve Bank of San Francisco (“FRB”). As of December 31, 2017, this line provided for maximum borrowings of $134,660,000 of which none was outstanding, leaving $134,660,000 available. As of December 31, 2017, the Company has designated investment securities with fair value of $17,000 and loans totaling $245,532,000 as potential collateral under this collateralized line of credit with the FRB. The Company has available unused correspondent banking lines of credit from commercial banks totaling $20,000,000 for federal funds transactions at December 31, 2017. Note 17 – Junior Subordinated Debt At December 31, 2017, the Company had five wholly-owned subsidiary business trusts that had issued $62.9 million of trust preferred securities (the “Capital Trusts”). Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”) of the Company. The Debentures are the sole assets of the trusts. The Company’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on or after specific dates, at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years. The Company organized two of the Capital Trusts. The Company acquired its three other Capital Trusts and assumed their related Debentures as a result of its acquisition of North Valley Bancorp. At the acquisition date of October 3, 2014, the Debentures associated with North Valley Bancorp’s three Capital Trusts were recorded on the Company’s books at their fair values of $5,006,000, $3,918,000, and $6,063,000, respectively. The related fair value discounts to face value of these Debentures will be amortized over the remaining time to maturity for each of these Debentures using the effective interest method. Similar, and proportional, discounts were applied to the acquired common stock interests in each of the acquired Capital Trusts and these discounts will be proportionally amortized over the remaining time to maturity for each related debenture. 83 Note 17 – Junior Subordinated Debt (continued) The recorded book values of the Debentures issued by the Capital Trusts are reflected as junior subordinated debt in the Company’s consolidated balance sheets. The common stock issued by the Capital Trusts and owned by the Company is recorded in other assets in the Company’s consolidated balance sheets. The recorded book value of the debentures issued by the Capital Trusts, less the recorded book value of the common stock of the Capital Trusts owned by the Company, continues to qualify as Tier 1 or Tier 2 capital under interim guidance issued by the Board of Governors of the Federal Reserve System. The following table summarizes the terms and recorded balance of each subordinated debenture as of the date indicated (dollars in thousands): Subordinated Debt Series TriCo Cap Trust I TriCo Cap Trust II North Valley Trust II North Valley Trust III North Valley Trust IV Maturity Date Face Value 10/7/2033 $20,619 20,619 7/23/2034 6,186 4/24/2033 5,155 4/24/2034 10,310 3/15/2036 $62,889 Coupon Rate (Variable) Current As of December 31, 2017 Recorded Book Value 3 mo.

These reserves are included in cash and due from banks in the accompanying consolidated balance sheets. Lease Commitments— The Company leases 48 sites under non-cancelable operating leases. The leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Substantially all of the leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term. The Company currently does not have any capital leases. At December 31, 2017, future minimum commitments under non-cancelable operating leases with initial or remaining terms of one year or more are as follows: 2018 2019 2020 2021 2022 Thereafter Future minimum lease payments Operating Leases (in thousands) $ $ 3,278 2,499 1,847 1,488 757 798 10,667 Rent expense under operating leases was $5,885,000 in 2017, $6,082,000 in 2016, and $6,241,000 in 2015. Rent expense was offset by rent income of $44,000 in 2017, $220,000 in 2016, and $217,000 in 2015. Financial Instruments with Off-Balance-Sheet Risk— The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and deposit account overdraft privilege. Those instruments involve, to varying degrees, elements of risk in excess of the amount recognized in the balance sheet. The contract amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit written is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company’s exposure to loss in the event of nonperformance by the other party to the financial instrument for deposit account overdraft privilege is represented by the overdraft privilege amount disclosed to the deposit account holder. 84 Note 18 – Commitments and Contingencies (continued) The following table presents a summary of the Bank’s commitments and contingent liabilities: (in thousands) Financial instruments whose amounts represent risk: Commitments to extend credit: Commercial loans Consumer loans Real estate mortgage loans Real estate construction loans Standby letters of credit Deposit account overdraft privilege December 31, 2017 December 31, 2016 $ 257,220 422,958 66,267 187,097 13,075 98,260 $ 220,836 406,855 42,184 97,399 12,763 98,583 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates of one year or less or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on Management’s credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, residential properties, and income-producing commercial properties. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements. Most standby letters of credit are issued for one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral requirements vary, but in general follow the requirements for other loan facilities. Deposit account overdraft privilege amount represents the unused overdraft privilege balance available to the Company’s deposit account holders who have deposit accounts covered by an overdraft privilege. The Company has established an overdraft privilege for certain of its deposit account products whereby all holders of such accounts who bring their accounts to a positive balance at least once every thirty days receive the overdraft privilege. The overdraft privilege allows depositors to overdraft their deposit account up to a predetermined level. The predetermined overdraft limit is set by the Company based on account type. Legal Proceedings — On September 15, 2014, a former Personal Banker at one of the Bank’s in-store branches filed a Class Action Complaint against the Bank in Butte County Superior Court, alleging causes of action related to the observance of meal and rest periods and seeking to represent a class of current and former branch employees with the same or similar job duties, employed by the Bank within the State of California during the preceding four years. On or about June 25, 2015, Plaintiff filed an Amended Complaint expanding the class definition to include all current and former non-exempt branch employees employed by the Bank within the State of California at any time during the period of September 15, 2010 to the entry of judgment. The Bank responded to the First Amended Complaint by denying the charges and the parties engaged in written discovery. The parties then engaged in non-binding mediation during the third quarter of 2016. In addition to this, on January 20, 2015, a then-current Personal Banker at one of the Bank’s in-store branches filed a First Amended Complaint against the Bank and the Company in Sacramento County Superior Court, alleging causes of action related to wage statement violations. As part of the Complaint Plaintiff is seeking to represent a class of current and former exempt and non-exempt employees who worked for the Company and/or the Bank during the time period of December 12, 2013 to the date of filing the action. The Company and the Bank responded to the First Amended Complaint by denying the charges and engaging in written discovery with Plaintiff. The parties then engaged in non-binding mediation of the action during the third quarter of 2016 as well. This matter was transferred to the Butte County Superior Court and consolidated with the case above, effective August 25, 2017. As part of the mediations, which took place concurrently, the Bank agreed in principal to settle the two matters in a consolidated settlement proceeding. The agreement was preliminarily approved by the court and notices were sent to the members of the purported classes. After reviewing the received claims, on January 12, 2018, the final settlement agreement was approved by the court. The total cost to the bank was $1,469,000, as compared to the balance accrued for litigation contingencies as of December 31, 2017 and 2016 of $1,450,000. Neither the Company nor its subsidiaries are a party to any other pending legal proceedings that are material, nor is their property the subject of any other material pending legal proceeding at this time. All other legal proceedings are routine and arise out of the ordinary course of the Bank’s business. None of those proceedings are currently expected to have a material adverse impact upon the Company’s and the Bank’s business, their consolidated financial position nor their operations in any material amount not already accrued, after taking into consideration any applicable insurance. 85 Note 18 – Commitments and Contingencies (continued) Other Commitments and Contingencies—The Company has entered into employment agreements or change of control agreements with certain officers of the Company providing severance payments and accelerated vesting of benefits under supplemental retirement agreements to the officers in the event of a change in control of the Company and termination for other than cause or after a substantial and material change in the officer’s title, compensation or responsibilities. The Bank owns 13,396 shares of Class B common stock of Visa Inc. which are convertible into Class A common stock at a conversion ratio of 1.648265 per Class B share. As of December 31, 2017, the value of the Class A shares was $114.02 per share. Utilizing the conversion ratio, the value of unredeemed Class A equivalent shares owned by the Bank was $2,518,000 as of December 31, 2017, and has not been reflected in the accompanying financial statements. The shares of Visa Class B common stock are restricted and may not be transferred. Visa Member Banks are required to fund an escrow account to cover settlements, resolution of pending litigation and related claims. If the funds in the escrow account are insufficient to settle all the covered litigation, Visa may sell additional Class A shares, use the proceeds to settle litigation, and further reduce the conversion ratio. If funds remain in the escrow account after all litigation is settled, the Class B conversion ratio will be increased to reflect that surplus. Mortgage loans sold to investors may be sold with servicing rights retained, with only the standard legal representations and warranties regarding recourse to the Bank. Management believes that any liabilities that may result from such recourse provisions are not significant. Note 19 – Shareholders’ Equity Dividends Paid The Bank paid to the Company cash dividends in the aggregate amounts of $19,236,000, $16,758,000, and $13,304,000 in 2017, 2016, and 2015, respectively. The Bank is regulated by the Federal Deposit Insurance Corporation (FDIC) and the State of California Department of Business Oversight. Absent approval from the Commissioner of the Department of Business Oversight, California banking laws generally limit the Bank’s ability to pay dividends to the lesser of (1) retained earnings or (2) net income for the last three fiscal years, less cash distributions paid during such period. Under this law, at December 31, 2017, the Bank could have paid dividends of $85,254,000 to the Company without the approval of the Commissioner of the Department of Business Oversight. Stock Repurchase Plan On August 21, 2007, the Board of Directors adopted a plan to repurchase, as conditions warrant, up to 500,000 shares of the Company’s common stock on the open market. The timing of purchases and the exact number of shares to be purchased will depend on market conditions. The 500,000 shares authorized for repurchase under this stock repurchase plan represented approximately 3.2% of the Company’s 15,814,662 outstanding common shares as of August 21, 2007. This stock repurchase plan has no expiration date. As of December 31, 2017, the Company had repurchased 166,600 shares under this plan. During the year ended December 31, 2017, there were no shares of common stock repurchased under this plan. Stock Repurchased Under Equity Compensation Plans During the years ended December 31, 2017, 2016, and 2015, employees tendered 107,390, 264,800, and 106,355 of the Company’s common stock with market value of $3,854,000, $7,879,000, and $2,868,000, respectively, in lieu of cash to exercise options to purchase shares of the Company’s stock and to pay income taxes related to such exercises as permitted by the Company’s shareholder- approved equity compensation plans. The tendered shares were retired. The market value of tendered shares is the last market trade price at closing on the day an option is exercised. Stock repurchased under equity incentive plans are not included in the total of stock repurchased under the stock repurchase plan announced August 21, 2007. 86 Note 20 – Stock Options and Other Equity-Based Incentive Instruments In March 2009, the Company’s Board of Directors adopted the TriCo Bancshares 2009 Equity Incentive Plan (2009 Plan) covering officers, employees, directors of, and consultants to, the Company. The 2009 Plan was approved by the Company’s shareholders in May 2009. The 2009 Plan allows for the granting of the following types of “stock awards” (Awards): incentive stock options, nonstatutory stock options, performance awards, restricted stock, restricted stock unit (RSU) awards and stock appreciation rights. RSUs that vest based solely on the grantee remaining in the service of the Company for a certain amount of time, are referred to as “service condition vesting RSUs”. RSUs that vest based on the grantee remaining in the service of the Company for a certain amount of time and a market condition such as the total return of the Company’s common stock versus the total return of an index of bank stocks, are referred to as “market plus service condition vesting RSUs”. In May 2013, the Company’s shareholders approved an amendment to the 2009 Plan increasing the maximum aggregate number of shares of TriCo’s common stock which may be issued pursuant to or subject to Awards from 650,000 to 1,650,000. The number of shares available for issuance under the 2009 Plan is reduced by: (i) one share for each share of common stock issued pursuant to a stock option or a Stock Appreciation Right and (ii) two shares for each share of common stock issued pursuant to a performance award, a restricted stock award or a RSU. When Awards made under the 2009 Plan expire or are forfeited or cancelled, the underlying shares will become available for future Awards under the 2009 Plan. To the extent that a share of common stock pursuant to an Award that counted as two shares against the number of shares again becomes available for issuance under the 2009 Plan, the number of shares of common stock available for issuance under the 2009 Plan shall increase by two shares. Shares awarded and delivered under the 2009 Plan may be authorized but unissued, or reacquired shares. As of December 31, 2017, 411,900 options for the purchase of common shares, and 121,286 RSUs were outstanding, and 527,039 shares remain available for issuance, under the 2009 Plan. In May 2001, the Company adopted the TriCo Bancshares 2001 Stock Option Plan (2001 Plan) covering officers, employees, directors of, and consultants to, the Company. Under the 2001 Plan, the option exercise price cannot be less than the fair market value of the Common Stock at the date of grant except in the case of substitute options. Options for the 2001 Plan expire on the tenth anniversary of the grant date. Vesting schedules under the 2001 Plan are determined individually for each grant. As of December 31, 2017, 34,500 options for the purchase of common shares were outstanding under the 2001 Plan. As of May 2009, as a result of the shareholder approval of the 2009 Plan, no new options may be granted under the 2001 Plan. Stock option activity is summarized in the following table for the dates indicated: Outstanding at December 31, 2016 Options granted Options exercised Options forfeited Outstanding at December 31, 2017 Number of Shares 592,250 — (145,850) — 446,400 Option Price per Share to to to to to $12.63 — $14.54 — $12.63 $23.21 — $22.54 — $23.21 Weighted Average Exercise Price $ 17.12 — $ 17.97 — $ 16.84 The following table shows the number, weighted-average exercise price, intrinsic value, and weighted average remaining contractual life of options exercisable, options not yet exercisable and total options outstanding as of December 31, 2017: Number of options Weighted average exercise price Intrinsic value (in thousands) Weighted average remaining contractual term (yrs.)

The 68,457 of service condition vesting RSUs outstanding as of December 31, 2017 are expected to vest, and be released, on a weighted-average basis, over the next 1.2 years. The Company expects to recognize $1,448,000 of pre-tax compensation costs related to these service condition vesting RSUs between December 31, 2017 and their vesting dates. The Company did not modify any service condition vesting RSUs during 2017 or 2016. The 52,829 of market plus service condition vesting RSUs outstanding as of December 31, 2017 are expected to vest, and be released, on a weighted-average basis, over the next 1.4 years. The Company expects to recognize $724,000 of pre-tax compensation costs related to these RSUs between December 31, 2017 and their vesting dates. As of December 31, 2017, the number of market plus service condition vesting RSUs outstanding that will actually vest, and be released, may be reduced to zero or increased to 79,243 depending on the total return of the Company’s common stock versus the total return of an index of bank stocks from the grant date to the vesting date.

The net change during the year in the deferred tax asset or liability results in a deferred tax expense or benefit. On December 22, 2017, President Donald Trump signed into law “H.R.1”, commonly known as the “Tax Cuts and Jobs Act”, which among other items reduces the Federal corporate tax rate from 35% to 21%. The Company’s deferred tax expense as of December 31, 2017 includes $7,416,000 from the re-measurement of deferred taxes and $226,000 from an acceleration of amortization expense on the low income housing tax credit investments. Taxes recorded directly to shareholders’ equity are not included in the preceding table. These taxes relating to changes in unfunded status of the supplemental retirement plans amounting to $400,000 in 2017, $429,000 in 2016, and $904,000 in 2015, taxes (benefits) related to unrealized gains and losses on available-for-sale investment securities amounting to $2,722,000 in 2017, $(4,631,000) in 2016, and $(797,000) in 2015, taxes (benefits) related to equity compensation of $0 in 2017, $(170,000) in 2016, and $(28,000) in 2015, were recorded directly to shareholders’ equity. The Company recognized, as components of tax expense, tax credits and other tax benefits, and amortization expense relating to our investments in Qualified Affordable Housing Projects as followers for the periods indicated: Year ended December 31, Tax credits and other tax benefits – decrease in tax expense Amortization – increase in tax expense 2017 $(1,753) $ 1,611 2016 (in thousands) $ $ (954) 757 2015 $(354) $ 277 The carrying value of Low Income Housing Tax Credit Funds was $16,854,000 and $18,465,000 as of December 31, 2017 and 2016, respectively. As of December 31, 2017, the Company has committed to make additional capital contributions to the Low Income Housing Tax Credit Funds in the amount of $8,554,000, and these contributions are expected to be made over the next several years. The provisions for income taxes applicable to income before taxes for the years ended December 31, 2017, 2016 and 2015 differ from amounts computed by applying the statutory Federal income tax rates to income before taxes. The effective tax rate and the statutory federal income tax rate are reconciled as follows: Federal statutory income tax rate State income taxes, net of federal tax benefit Tax Cuts and Jobs Act impact on deferred re-measurement Tax-exempt interest on municipal obligations Tax-exempt life insurance related income Equity compensation Low income housing tax credit benefits Low income housing tax credit amortization Non-deductible joint beneficiary agreement expense Non-deductible merger expense Other Effective Tax Rate 90 Years Ended December 31, 2016 35.0% 6.8 — (1.8) (1.3) — (1.3) 0.8 0.1 — (0.1) 38.2% 2017 35.0% 6.9 9.6 (1.9) (1.3) (1.2) (2.3) 2.1 0.1 0.2 0.5 47.7% 2015 35.0% 6.6 — (0.7) (1.3) — (0.4) — 0.1 — 0.4 39.7% Note 22 – Income Taxes (continued) The temporary differences, tax effected, which give rise to the Company’s net deferred tax asset recorded in other assets are as follows as of December 31 for the years indicated: Deferred tax assets: Allowance for losses and reserve for unfunded commitments Deferred compensation Accrued pension liability Accrued bonus Other accrued expenses Unfunded status of the supplemental retirement plans State taxes Share based compensation Nonaccrual interest OREO write downs Indemnification asset Acquisition cost basis Unrealized loss on securities Tax credits Net operating loss carryforwards Other Total deferred tax assets Deferred tax liabilities: Securities income Depreciation Merger related fixed asset valuations Securities accretion Mortgage servicing rights valuation Core deposit intangible Junior subordinated debt Prepaid expenses and other Total deferred tax liability Net deferred tax asset 2017 2016 (in thousands) $ 9,900 1,953 6,835 171 522 1,582 1,397 1,322 282 59 — 2,187 1,008 581 1,801 508 30,108 (958) (1,987) (30) (315) (1,943) (916) (1,783) (479) (8,411) $ 14,809 2,743 9,220 1,727 781 1,982 2,257 2,063 408 132 313 3,996 3,730 491 3,354 981 48,987 (1,362) (3,032) (54) (478) (2,710) (1,813) (2,616) (723) (12,788) $21,697 $ 36,199 As part of the merger with North Valley Bancorp in 2014, TriCo acquired federal and state net operating loss carryforwards, capital loss carryforwards, and tax credit carryforwards. These tax attribute carryforwards will be subject to provisions of the tax law that limit the use of such losses and credits generated by a company prior to the date certain ownership changes occur. The amount of the Company’s net operating loss carryforwards that would be subject to these limitations as of December 31, 2017 were $21.4 million for California. The amount of the Company’s tax credits that would be subject to these limitations as of December 31, 2017 are $69,000 and $648,000 for federal and California, respectively. Due to the limitation, a significant portion of the state tax credits will expire regardless of whether the Company generates future taxable income. As such, the Company has recorded the future benefit of these tax credits on the books at the value which is more likely than not to be realized. These tax loss and tax credit carryforwards expire at various dates beginning in 2018. The Company believes that a valuation allowance is not needed to reduce the deferred tax assets as it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets, including the tax attribute carryforwards acquired as part of the North Valley Bancorp merger. As part of the North Valley Bancorp merger, TriCo inherited an unrecognized tax benefit for tax positions claimed on prior year tax returns filed by North Valley Bancorp. The Company had an unrecognized tax benefit of $60,000 as of December 31, 2017, the recognition of which would reduce the Company’s tax expense by $34,000. Management does not expect the unrecognized tax benefit will materially change in the next 12 months. A summary of changes in the Company’s unrecognized tax benefit (including interest and penalties) in 2017 is as follows: (in thousands) As of December 31, 2016 Lapse of the applicable statute of limitations As of December 31, 2017 UTB $114 (54) $ 60 Interest/Penalties 7 $ (5) 2 $ Total $121 (59) $ 62 During the years ended December 31, 2017 and December 31, 2016 the Company recognized no interest and penalties related to taxes. The Company files income tax returns in the U.S. federal jurisdiction, and California. With few exceptions, the Company is no longer subject to U.S. federal and state/local income tax examinations by tax authorities for years before 2014 and 2013, respectively. 91 Note 23 – Earnings per Share Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from assumed issuance. Potential common shares that may be issued by the Company relate solely from outstanding stock options, and are determined using the treasury stock method. Earnings per share have been computed based on the following: Net income (in thousands) Years ended December 31, 2016 $44,811 2017 $40,554 2015 $43,818 (number of shares in thousands) Average number of common shares outstanding Effect of dilutive stock options Average number of common shares outstanding used to calculate diluted earnings per share 22,912 338 22,814 273 22,750 248 23,250 23,087 22,998 Based on an average of quarterly computations, there were 0, 13,825, and 20,625 options and restricted stock units excluded from the computation of annual diluted earnings per share for the years ended December 31, 2017, 2016 and 2015, respectively, because the effect of these options and restricted stock units were antidilutive. Note 24 – Comprehensive Income Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. The components of other comprehensive income and related tax effects are as follows: Unrealized holding losses on available for sale securities before reclassifications Amounts reclassified out of accumulated other comprehensive income Unrealized holding losses on available for sale securities after reclassifications Tax effect Unrealized holding losses on available for sale securities, net of tax Change in unfunded status of the supplemental retirement plans before reclassifications Amounts reclassified out of accumulated other comprehensive income: Amortization of prior service cost Amortization of actuarial losses Total amounts reclassified out of accumulated other comprehensive income Change in unfunded status of the supplemental retirement plans after reclassifications Tax effect Change in unfunded status of the supplemental retirement plans, net of tax Change in joint beneficiary agreement liability before reclassifications Amounts reclassified out of accumulated other comprehensive income Change in joint beneficiary agreement liability after reclassifications Tax effect Change in joint beneficiary agreement liability, net of tax Total other comprehensive income (loss) $ 2,685 92 2017 Years Ended December 31, 2016 (in thousands) 2015 $ 6,422 $(11,015) (961) — $(1,895) — 5,461 (2,296) 3,165 (11,015) 4,631 (6,384) (1,895) 797 (1,098) (1,016) 511 1,384 (12) 390 378 (638) 268 (370) (110) — (110) — (110) (40) 550 510 (57) 823 766 1,021 (429) 2,150 (904) 592 (343) — (343) — (343) $ (6,135) 1,246 277 — 277 — 277 425 $ Note 24 – Comprehensive Income (continued) The components of accumulated other comprehensive income, included in shareholders’ equity, are as follows: Net unrealized gains on available for sale securities Tax effect Unrealized holding gains on available for sale securities, net of tax Unfunded status of the supplemental retirement plans Tax effect Unfunded status of the supplemental retirement plans, net of tax Joint beneficiary agreement liability Tax effect Joint beneficiary agreement liability, net of tax Accumulated other comprehensive loss December 31, 2017 2016 (in thousands) $(3,409) 1,008 (2,401) (5,352) 2,250 (3,102) (150) — (150) $(5,228) $(8,870) 3,729 (5,141) (4,714) 1,982 (2,732) (40) — (40) $(7,913) Note 25 – Retirement Plans 401(k) Plan The Company sponsors a 401(k) Plan whereby substantially all employees age 21 and over with 90 days of service may participate. Participants may contribute a portion of their compensation subject to certain limits based on federal tax laws. Prior to July 1, 2015, the Company did not contribute to the 401(k) Plan. Effective July 1, 2015, the Company initiated a discretionary matching contribution equal to 50% of participant’s elective deferrals each quarter, up to 4% of eligible compensation. The Company recorded $776,000, $678,000, and $300,000, of salaries & benefits expense attributable to the 401(k) Plan matching contribution during the years 2017, 2016, and 2015, respectively. The Company made $767,000, $811,000, and $0, of 401(k) Plan matching contributions during the years 2017, 2016, and 2015, respectively. Employee Stock Ownership Plan Substantially all employees with at least one year of service are covered by a discretionary employee stock ownership plan (ESOP). Contributions are made to the plan at the discretion of the Board of Directors. Contributions to the plan totaling $2,073,000, $1,368,000, and $2,651,000 were made during 2017, 2016, and 2015, respectively. Expenses related to the Company’s ESOP, are included in benefits and other compensation costs under salaries and benefits expense, and were $2,149,000, $1,831,000, and $2,282,000 during 2017, 2016, and 2015, respectively. Company shares owned by the ESOP are paid dividends and included in the calculation of earnings per share exactly as other common shares outstanding. Deferred Compensation Plans The Company has deferred compensation plans for certain directors and key executives, which allow certain directors and key executives designated by the Board of Directors of the Company to defer a portion of their compensation. The Company has purchased insurance on the lives of the participants and intends to hold these policies until death as a cost recovery of the Company’s deferred compensation obligations of $6,605,000, and $6,525,000 at December 31, 2017 and 2016, respectively. Earnings credits on deferred balances totaling $478,000 in 2017, $487,000 in 2016, and $538,000 in 2015 are included in noninterest expense. Supplemental Retirement Plans The Company has supplemental retirement plans for certain directors and key executives. These plans are non-qualified defined benefit plans and are unsecured and unfunded. The Company has purchased insurance on the lives of the participants and intends to hold these policies until death as a cost recovery of the Company’s retirement obligations. The cash values of the insurance policies purchased to fund the deferred compensation obligations and the supplemental retirement obligations were $97,783,000 and $95,912,000 at December 31, 2017 and 2016, respectively. The Company recorded in other liabilities the unfunded status of the supplemental retirement plans of $5,352,000 and $4,714,000 related to the supplemental retirement plans as of December 31, 2017 and 2016, respectively. These amounts represent the amount by which the projected benefit obligations for these retirement plans exceeded the fair value of plan assets plus amounts previously accrued related to the plans. The projected benefit obligation is recorded in other liabilities. 93 Note 25 – Retirement Plans (continued) At December 31, 2017 and 2016, the unfunded status of the supplemental retirement plans of $5,352,000 and $4,714,000 were offset by a reduction of shareholders’ equity accumulated other comprehensive loss of $3,102,000 and $2,732,000, respectively, representing the after-tax impact of the unfunded status of the supplemental retirement plans, and the related deferred tax asset of $2,250,000 and $1,982,000, respectively. Amounts recognized as a component of accumulated other comprehensive loss as of year-end that have not been recognized as a component of the combined net period benefit cost of the Company’s defined benefit pension plans are presented in the following table. The Company expects to recognize approximately $509,000 of the net actuarial loss reported in the following table as of December 31, 2017 as a component of net periodic benefit cost during 2018.

Note 27 – Fair Value Measurement The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, income approach, and/or the cost approach. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. Securities available-for-sale and mortgage servicing rights are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as loans held for sale, loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or impairment write-downs of individual assets. The Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observable nature of the assumptions used to determine fair value. These levels are: Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 - Level 3 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. 95 Securities available for sale - Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. The Company had no securities classified as Level 3 during any of the periods covered in these financial statements. Loans held for sale – Loans held for sale are carried at the lower of cost or fair value. The fair value of loans held for sale is based on what secondary markets are currently offering for loans with similar characteristics. As such, we classify those loans subjected to nonrecurring fair value adjustments as Level 2. Impaired originated and PNCI loans – Originated and PNCI loans are not recorded at fair value on a recurring basis. However, from time to time, an originated or PNCI loan is considered impaired and an allowance for loan losses is established. Originated and PNCI loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. The fair value of an impaired originated or PNCI loan is estimated using one of several methods, including collateral value, fair value of similar debt, enterprise value, liquidation value and discounted cash flows. Those impaired originated and PNCI loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. Impaired originated and PNCI loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the impaired originated or PNCI loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the impaired originated or PNCI loan as nonrecurring Level 3. Foreclosed assets - Foreclosed assets include assets acquired through, or in lieu of, loan foreclosure. Foreclosed assets are held for sale and are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value less cost to sell. When the fair value of foreclosed assets is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the impaired originated loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the foreclosed asset as nonrecurring Level 3. Revenue and expenses from operations and changes in the valuation allowance are included in other noninterest expense. Mortgage servicing rights - Mortgage servicing rights are carried at fair value. A valuation model, which utilizes a discounted cash flow analysis using a discount rate and prepayment speed assumptions is used in the computation of the fair value measurement. While the prepayment speed assumption is currently quoted for comparable instruments, the discount rate assumption currently requires a significant degree of management judgment and is therefore considered an unobservable input. As such, the Company classifies mortgage servicing rights subjected to recurring fair value adjustments as Level 3. Additional information regarding mortgage servicing rights can be found in Note 10 in the consolidated financial statements at Item 1 of this report. The table below presents the recorded amount of assets and liabilities measured at fair value on a recurring basis (in thousands): Fair value at December 31, 2017 Securities available-for-sale: Obligations of U.S. government corporations and agencies Obligations of states and political subdivisions Marketable equity securities Mortgage servicing rights Total assets measured at fair value Fair value at December 31, 2016 Securities available-for-sale: Obligations of U.S. government corporations and agencies Obligations of states and political subdivisions Marketable equity securities Mortgage servicing rights Total assets measured at fair value 96 Total Level 1 Level 2 Level 3 $604,789 123,156 2,938 6,687 $737,570 — — $2,938 — $2,938 $604,789 123,156 — — $727,945 — — — $6,687 $6,687 Total Level 1 Level 2 Level 3 $429,678 117,617 2,938 6,595 $556,828 — — $2,938 — $2,938 $429,678 117,617 — — $547,295 — — — $6,595 $6,595 Note 27 – Fair Value Measurement (continued) Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally corresponds with the Company’s quarterly valuation process. There were no transfers between any levels during 2017 or 2016. The following table provides a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the years ended December 31, 2017, 2016, and 2015. Had there been any transfer into or out of Level 3 during 2017, 2016, or 2015, the amount included in the “Transfers into (out of) Level 3” column would represent the beginning balance of an item in the period (interim quarter) during which it was transferred (in thousands): Year ended December 31, 2017: Mortgage servicing rights 2016: Mortgage servicing rights 2015: Mortgage servicing rights Ending Balance $6,687 $6,595 $7,618 Transfers into (out of) Level 3 Change Included in Earnings — — — $ (718) $ (2,184) (701) $ Issuances $ 810 $ 1,161 941 $ Beginning Balance $ 6,595 $ 7,618 $ 7,378 The Company’s method for determining the fair value of mortgage servicing rights is described in Note 1. The key unobservable inputs used in determining the fair value of mortgage servicing rights are mortgage prepayment speeds and the discount rate used to discount cash projected cash flows. Generally, any significant increases in the mortgage prepayment speed and discount rate utilized in the fair value measurement of the mortgage servicing rights will result in a negative fair value adjustments (and decrease in the fair value measurement). Conversely, a decrease in the mortgage prepayment speed and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement). Note 10 contains additional information regarding mortgage servicing rights. The following table presents quantitative information about recurring Level 3 fair value measurements at December 31, 2017 and 2016: Fair Value (in thousands) Valuation Technique Unobservable Inputs Range, Weighted Average December 31, 2017 Mortgage Servicing Rights December 31, 2016 Mortgage Servicing Rights $ $ 6,687 Discounted cash flow Constant prepayment rate Discount rate 6.2%-22.0%, 8.9% 13.0%-15.0%, 13.0% 6,595 Discounted cash flow Constant prepayment rate Discount rate 6.9%-16.6%, 8.8% 14.0%-16.0%, 14.0% The tables below present the recorded amount of assets and liabilities measured at fair value on a nonrecurring basis, as of the dates indicated, that had a write-down or an additional allowance provided during the periods indicated (in thousands): Year ended December 31, 2017 Fair value: Impaired Originated & PNCI loans Foreclosed assets Total assets measured at fair value Year ended December 31, 2016 Fair value: Impaired Originated & PNCI loans Foreclosed assets Total assets measured at fair value Total Level 1 Level 2 Level 3 Total Gains (Losses) $2,767 2,217 $4,984 — — — — $2,767 2,217 $4,984 $ (1,452) (135) $ (1,587) Total Level 1 Level 2 Level 3 Total Gains (Losses) $1,107 2,253 $3,360 — — — — $1,107 2,253 $3,360 $ $ (409) (86) (495) The impaired Originated and PNCI loan amount above represents impaired, collateral dependent loans that have been adjusted to fair value. When we identify a collateral dependent loan as impaired, we measure the impairment using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan, the fair value of collateral is generally estimated by obtaining external appraisals. If we determine that the value of the impaired loan is less than the recorded investment in the loan, we recognize this impairment and adjust the carrying value of the loan to fair value through the allowance for loan and lease losses. The loss represents charge-offs or impairments on collateral dependent loans for fair value adjustments based on the fair value of collateral. The carrying value of loans fully charged-off is zero. The foreclosed assets amount above represents impaired real estate that has been adjusted to fair value. Foreclosed assets represent real estate which the Bank has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at fair value less costs to sell, which becomes the property’s new basis. Any write-downs based on the asset’s fair value at the date of acquisition are charged to the allowance for loan and lease losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on non-covered other real estate owned for fair value adjustments based on the fair value of the real estate. 97 Note 27 – Fair Value Measurement (continued) The Company’s property appraisals are primarily based on the sales comparison approach and income approach methodologies, which consider recent sales of comparable properties, including their income generating characteristics, and then make adjustments to reflect the general assumptions that a market participant would make when analyzing the property for purchase. These adjustments may increase or decrease an appraised value and can vary significantly depending on the location, physical characteristics and income producing potential of each property. Additionally, the quality and volume of market information available at the time of the appraisal can vary from period to period and cause significant changes to the nature and magnitude of comparable sale adjustments. Given these variations, comparable sale adjustments are generally not a reliable indicator for how fair value will increase or decrease from period to period. Under certain circumstances, management discounts are applied based on specific characteristics of an individual property. The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a nonrecurring basis at December 31, 2017 and 2016: December 31, 2017 Impaired Originated & PNCI loans Fair Value (in thousands) $ 2,767 Foreclosed assets (Land & $ 1,341 construction) Foreclosed assets (residential (Residential real estate) Foreclosed assets (Commercial real $ $ 622 254 estate) December 31, 2016 Impaired Originated & PNCI loans Fair Value (in thousands) $ 1,107 Foreclosed assets (Land & $ 15 construction) Foreclosed assets (residential (Residential real estate) Foreclosed assets (Commercial real $ $ 1,564 674 estate) Valuation Technique Sales comparison approach Income approach Sales comparison approach Sales comparison approach Sales comparison approach Valuation Technique Sales comparison approach Income approach Sales comparison approach Sales comparison approach Sales comparison approach Unobservable Inputs Adjustment for differences between comparable sales Capitalization rate Adjustment for differences between comparable sales Adjustment for differences between comparable sales Adjustment for differences between comparable sales Unobservable Inputs Adjustment for differences between comparable sales Capitalization rate Adjustment for differences between comparable sales Adjustment for differences between comparable sales Adjustment for differences between comparable sales Range, Weighted Average Not meaningful N/A Not meaningful Not meaningful Not meaningful Range, Weighted Average Not meaningful N/A Not meaningful Not meaningful Not meaningful In addition to the methods and assumptions used to estimate the fair value of each class of financial instrument noted above, the following methods and assumptions were used to estimate the fair value of other classes of financial instruments for which it is practical to estimate the fair value. Short-term Instruments - Cash and due from banks, fed funds purchased and sold, interest receivable and payable, and short-term borrowings are considered short-term instruments. For these short-term instruments their carrying amount approximates their fair value. Securities held to maturity – The fair value of securities held to maturity is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. The Company had no securities held to maturity classified as Level 3 during any of the periods covered in these financial statements. Restricted Equity Securities - It is not practical to determine the fair value of restricted equity securities due to restrictions placed on their transferability. Originated and PNCI loans - The fair value of variable rate originated and PNCI loans is the current carrying value. The interest rates on these originated and PNCI loans are regularly adjusted to market rates. The fair value of other types of fixed rate originated and PNCI loans is estimated by discounting the future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings for the same remaining maturities. The allowance for loan losses is a reasonable estimate of the valuation allowance needed to adjust computed fair values for credit quality of certain originated and PNCI loans in the portfolio. PCI Loans - PCI loans are measured at estimated fair value on the date of acquisition. Carrying value is calculated as the present value of expected cash flows and approximates fair value. Deposit Liabilities - The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. These values do not consider the estimated fair value of the Company’s core deposit intangible, which is a significant unrecognized asset of the Company. The fair value of time deposits and other borrowings is based on the discounted value of contractual cash flows. Other Borrowings - The fair value of other borrowings is calculated based on the discounted value of the contractual cash flows using current rates at which such borrowings can currently be obtained. 98 Note 27 – Fair Value Measurement (continued) Junior Subordinated Debentures - The fair value of junior subordinated debentures is estimated using a discounted cash flow model. The future cash flows of these instruments are extended to the next available redemption date or maturity date as appropriate based upon the spreads of recent issuances or quotes from brokers for comparable bank holding companies compared to the contractual spread of each junior subordinated debenture measured at fair value. Accrued Interest Receivable and Payable - Specific identification of the carrying value and fair value of accrued interest receivable and payable are not considered significant for financial reporting purposes, however, their fair value hierarchy would be based on the of the related asset or liability. Commitments to Extend Credit and Standby Letters of Credit - The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present credit worthiness of the counter parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligation with the counter parties at the reporting date. Fair values for financial instruments are management’s estimates of the values at which the instruments could be exchanged in a transaction between willing parties. These estimates are subjective and may vary significantly from amounts that would be realized in actual transactions. In addition, other significant assets are not considered financial assets including, any mortgage banking operations, deferred tax assets, and premises and equipment. Further, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates and have not been considered in any of these estimates. The estimated fair values of financial instruments that are reported at amortized cost in the Corporation’s consolidated balance sheets, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value, were as follows (in thousands): Financial assets: Level 1 inputs: Cash and due from banks Cash at Federal Reserve and other banks $ 105,968 99,460 $ 105,968 99,460 $ 92,197 213,415 $ 92,197 213,415 December 31, 2017 December 31, 2016 Carrying Amount Fair Value Carrying Amount Fair Value Level 2 inputs: Securities held to maturity Restricted equity securities Loans held for sale Level 3 inputs: Loans, net Financial liabilities: Level 2 inputs: Deposits Other borrowings Level 3 inputs: 514,844 16,956 4,616 518,165 N/A 4,616 602,536 16,596 2,998 603,203 N/A 2,998 2,984,842 2,992,225 2,727,090 2,763,473 4,009,131 122,166 4,006,620 122,166 3,895,560 17,493 3,893,941 17,493 Junior subordinated debt $ 56,858 $ 58,466 $ 56,667 $ 49,033 Off-balance sheet: Level 3 inputs: Commitments Standby letters of credit Overdraft privilege commitments Contract Amount Fair Value Contract Amount Fair Value $ 933,542 13,075 $ 98,260 $ $ $ $ 9,335 131 983 $ 767,274 12,763 $ 98,583 $ $ $ $ 7,673 128 986 99 Note 28 – TriCo Bancshares Condensed Financial Statements (Parent Only) Condensed Balance Sheets Assets Cash and Cash equivalents Investment in Tri Counties Bank Other assets Total assets Liabilities and shareholders’ equity Other liabilities Junior subordinated debt Total liabilities Shareholders’ equity: Common stock, no par value: authorized 50,000,000 shares; issued and outstanding 22,955,963 and 22,867,802 shares, respectively Retained earnings Accumulated other comprehensive loss, net Total shareholders’ equity Total liabilities and shareholders’ equity Condensed Statements of Income 2017 December 31, 2017 2016 (in thousands) $ 3,924 557,538 1,721 $563,183 $ 517 56,858 57,375 $ 2,802 529,907 1,711 $534,420 $ 406 56,667 57,073 255,836 255,200 (5,228) 505,808 $563,183 252,820 232,440 (7,913) 477,347 $534,420 Interest expense Administration expense Loss before equity in net income of Tri Counties Bank Equity in net income of Tri Counties Bank: Distributed Undistributed Income tax benefit Net income Condensed Statements of Comprehensive Income 2017 Net income Other comprehensive income (loss), net of tax: Unrealized holding gains (losses) on securities arising during the period Change in minimum pension liability Change in joint beneficiary agreement liability Other comprehensive income (loss) Comprehensive income Condensed Statements of Cash Flows Operating activities: Net income Adjustments to reconcile net income to net cash provided by operating activities: Undistributed equity in earnings of Tri Counties Bank Equity compensation vesting expense Equity compensation tax effect Net change in other assets and liabilities Net cash provided by operating activities Investing activities: None Financing activities: Issuance of common stock through option exercise Equity compensation tax effect Repurchase of common stock Cash dividends paid — common Net cash used for financing activities Increase in cash and cash equivalents Cash and cash equivalents at beginning of year Cash and cash equivalents at end of year 100 Years ended December 31, 2016 (in thousands) $ (2,229) (725) (2,954) $ (2,535) (915) (3,450) 2015 $ (1,977) (814) (2,791) 19,236 23,359 1,409 $ 40,554 16,758 29,764 1,243 $ 44,811 13,304 32,131 1,174 $ 43,818 Years ended December 31, 2016 (in thousands) $ 44,811 2015 $ 43,818 $ 40,554 3,165 (370) (110) 2,685 $ 43,239 (6,384) 592 (343) (6,135) $ 38,676 (1,098) 1,246 277 425 $ 44,243 2017 Years ended December 31, 2016 (in thousands) 2015 $ 40,554 $ 44,811 $ 43,818 (23,359) 1,586 — (1,295) 17,486 (29,764) 1,467 (155) (1,210) 15,149 (32,131) 1,370 68 (1,120) 12,005 396 — (1,629) (15,131) (16,364) 1,122 2,802 $ 3,924 518 155 (1,890) (13,695) (14,912) 237 2,565 $ 2,802 660 (68) (412) (11,849) (11,669) 336 2,229 $ 2,565 Note 29 – Regulatory Matters The Company is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1, and common equity Tier 1capital to risk-weighted assets, and of Tier 1 capital to average assets. The following tables present actual and required capital ratios as of December 31, 2017 and 2016 for the Company and the Bank under Basel III Capital Rules. The minimum capital amounts presented include the minimum required capital levels as of December 31, 2017 and 2016 based on the phased-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. As of December 31, 2017: Total Capital (to Risk Weighted Assets): Consolidated Tri Counties Bank Tier 1 Capital (to Risk Weighted Assets): Consolidated Tri Counties Bank Common equity Tier 1 Capital (to Risk Weighted Assets): Consolidated Tri Counties Bank Tier 1 Capital (to Average Assets): Consolidated Tri Counties Bank As of December 31, 2016: Total Capital (to Risk Weighted Assets): Consolidated Tri Counties Bank Tier 1 Capital (to Risk Weighted Assets): Consolidated Tri Counties Bank Common equity Tier 1 Capital (to Risk Weighted Assets): Consolidated Tri Counties Bank Tier 1 Capital (to Average Assets): Consolidated Tri Counties Bank Actual Amount Ratio Minimum Capital Required – Basel III Phase-in Schedule Ratio Amount Minimum Capital Required – Basel III Fully Phased In Amount Ratio (dollars in thousands) Required to be Considered Well Capitalized Amount Ratio $528,805 $525,384 14.07% $347,694 13.98% $347,535 9.250% $394,679 9.250% $394,499 10.50% N/A 10.50% $375,713 N/A 10.00% $495,318 $491,897 13.18% $272,517 13.09% $272,392 7.250% $319,502 7.250% $319,356 N/A 8.50% 8.50% $300,570 N/A 8.00% $440,643 $491,897 11.72% $216,134 13.09% $216,035 5.750% $263,120 5.750% $262,999 N/A 7.00% 7.00% $244,214 $495,318 $491,897 10.80% $183,400 10.73% $183,394 4.000% $183,400 4.000% $183,394 4.00% N/A 4.00% $229,243 N/A 6.50% N/A 5.00% $503,283 $500,876 14.77% $293,854 14.71% $293,706 8.625% $357,735 8.625% $357,556 N/A 10.50% 10.50% $340,529 N/A 10.00% $468,061 $465,654 13.74% $225,714 13.67% $225,601 6.625% $289,595 6.625% $289,450 N/A 8.50% 8.50% $274,725 N/A 8.00% $414,632 $465,654 12.17% $174,609 13.66% $174,521 5.125% $238,490 5.125% $238,370 7.00% N/A 7.00% $221,344 $468,061 $465,654 10.62% $176,346 10.56% $176,341 4.000% $176,346 4.000% $176,341 4.00% N/A 4.00% $220,426 N/A 6.50% N/A 5.00% As of December 31, 2017, capital levels at the Company and the Bank exceed all capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis. Also, at December 31, 2017 and December 31, 2016, the Bank’s capital levels exceeded the minimum amounts necessary to be considered well capitalized under the current regulatory framework for prompt corrective action. Beginning January 1, 2016, the Basel III Capital Rules implemented a requirement for all banking organizations to maintain a capital conservation buffer above the minimum risk-based capital requirements in order to avoid certain limitations on capital distributions, stock repurchases and discretionary bonus payments to executive officers. The capital conservation buffer is exclusively composed of common equity tier 1 capital, and it applies to each of the risk-based capital ratios but not the leverage ratio. At December 31, 2017 and 2016, the Company and the Bank were in compliance with the capital conservation buffer requirements, which were 1.25% and 0.625%, respectively. The three risk-based capital ratios will increase by 0.625% each year through 2019, at which point, the common equity tier 1 risk-based, tier 1 risk-based and total risk-based capital ratio minimums will be 7.0%, 8.5% and 10.5%, respectively. 101 Note 30 – Summary of Quarterly Results of Operations (unaudited) The following table sets forth the results of operations for the four quarters of 2017 and 2016, and is unaudited; however, in the opinion of Management, it reflects all adjustments (which include only normal recurring adjustments) necessary to present fairly the summarized results for such periods.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Under the supervision and with the participation of management, including the principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in the 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation under the framework in the 2013 Internal Control – Integrated Framework, management of the Company has concluded the Company maintained effective internal control over financial reporting, as such term is defined in Securities Exchange Act of 1934 Rules 13a-15(f), as of December 31, 2017. Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting can also be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. Management is also responsible for the preparation and fair presentation of the consolidated financial statements and other financial information contained in this report. The accompanying consolidated financial statements were prepared in conformity with U.S. generally accepted accounting principles and include, as necessary, best estimates and judgments by management. In addition to management’s assessment, Crowe Horwath LLP, an independent registered public accounting firm, has audited the Company’s consolidated financial statements as of and for the year ended December 31, 2017, and the Company’s effectiveness of internal control over financial reporting as of December 31, 2017, dated March 1, 2018, as stated in its report, which is included herein. /s/ Richard P.

We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO. Basis for Opinions The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We have served as the Company’s auditor since 2012. Sacramento, California March 1, 2018 104 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None.

Defined terms not explicitly defined in this Stock Option Agreement but defined in the Plan shall have the same definitions as in the Plan. The details of your option are as follows: 1. VESTING. Subject to the limitations contained herein, your option will vest as provided in your Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. 2. NUMBER OF SHARES AND EXERCISE PRICE. The number of shares of Common Stock subject to your option and your exercise price per share referenced in your Grant Notice may be adjusted from time to time for Capitalization Adjustments. 3. METHOD OF PAYMENT. Payment of the exercise price is due in full upon exercise of all or any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner permitted by your Grant Notice, which may include one or more of the following: (a) Bank draft or money order payable to the Company. (b) In the Company’s sole discretion at the time your option is exercised and provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds (“Cashless Exercise”). (c) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, by delivery of already-owned shares of Common Stock either that you have held for the period required to avoid a charge to the Company’s reported earnings (generally six (6) months) or that you did not acquire, directly or indirectly from the Company, that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. “Delivery” for these purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. (d) Provided that at the time of exercise the Company has adopted FAS 123, as revised, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or other payment from you to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued; provided further, however, that shares of Common Stock will no longer be outstanding under your option and will not be exercisable thereafter to the extent that (1) shares are used to pay the exercise price pursuant to the “net exercise,” (2) shares are delivered to you as a result of such exercise, and (3) shares are withheld to satisfy tax withholding obligations. 4. WHOLE SHARES. You may exercise your option only for whole shares of Common Stock. 5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option also must comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 6. TERM. You may not exercise your option before the commencement or after the expiration of its term. The term of your option commences on the Date of Grant and expires upon the earliest of the following: (a) three (3) months after the termination of your Continuous Service for any reason other than your Disability or death, provided that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the above section “Securities Law Compliance,” your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; (b) three (3) months after the termination of your Continuous Service due to your Disability; (c) three (3) months after your death if you die either during your Continuous Service or within three (3) months after your Continuous Service terminates; (d) the Expiration Date indicated in your Grant Notice; or (e) the day before the tenth (10th) anniversary of the Date of Grant. If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option, the Code requires that at all times beginning on the date of grant of your option and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate terminates. 7. EXERCISE. (a) You may exercise the vested portion of your option during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. (b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option, (2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. (c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one (1) year after such shares of Common Stock are transferred upon exercise of your option. 8. TRANSFERABILITY. Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. 9. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective shareholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 10. WITHHOLDING OBLIGATIONS. (a) At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of your option. (b) Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid variable award accounting). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. (c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any escrow provided for herein unless such obligations are satisfied. 11. NOTICES. Any notices provided for in your option or the Plan shall be given in writing or shall be delivered electronically, and shall be deemed effectively given or delivered upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 12. GOVERNING PLAN DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control. This Stock Option Agreement shall be deemed to be signed by the Company and the Participant upon the electronic acceptance by the Participant of the applicable Stock Option Grant Notice. * * * * * Trico Bancshares 2009 EQUITY INCENTIVE PLAN STOCK APPRECIATION RIGHT AGREEMENT Pursuant to your Stock Appreciation Grant Notice (“Grant Notice”) and this Stock Appreciation Right Agreement, Trico Bancshares (the “Company”) has granted you an stock appreciation right under its 2009 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in your Grant Notice at the exercise price indicated in your Grant Notice. Defined terms not explicitly defined in this Stock Appreciation Right Agreement but defined in the Plan shall have the same definitions as in the Plan. The details of your stock appreciation right are as follows: 1. VESTING. Subject to the limitations contained herein, your stock appreciation right will vest as provided in your Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. 2. NUMBER OF SHARES AND EXERCISE PRICE. The number of shares of Common Stock subject to your stock appreciation right and your exercise price per share referenced in your Grant Notice may be adjusted from time to time for Capitalization Adjustments. 3. CALCULATION OF APPRECIATION. The appreciation distribution payable on the exercise of a Stock Appreciation Right will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the Stock Appreciation Right) of a number of shares of Common Stock equal to the number of shares of Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to which the Participant is exercising the Stock Appreciation Right on such date, over (B) the strike price that will be determined by the Board at the time of grant of the Stock Appreciation Right. 4. WHOLE SHARES. You may exercise your stock appreciation right only for whole shares of Common Stock. 5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, you may not exercise your stock appreciation right unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your stock appreciation right also must comply with other applicable laws and regulations governing your stock appreciation right, and you may not exercise your stock appreciation right if the Company determines that such exercise would not be in material compliance with such laws and regulations. 6. TERM. You may not exercise your stock appreciation right before the commencement or after the expiration of its term. The term of your stock appreciation right commences on the Date of Grant and expires upon the earliest of the following: (a) three (3) months after the termination of your Continuous Service for any reason other than your Disability or death, provided that if during any part of such three (3) month period your stock appreciation right is not exercisable solely because of the condition set forth in the above section “Securities Law Compliance,” your stock appreciation right shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; (b) three (3) months after the termination of your Continuous Service due to your Disability; (c) three (3) months after your death if you die either during your Continuous Service or within three (3) months after your Continuous Service terminates; (d) the Expiration Date indicated in your Grant Notice; or (e) the day before the tenth (10th) anniversary of the Date of Grant. 7. EXERCISE. (a) You may exercise the vested portion of your stock appreciation right during its term by delivering a Notice of Exercise (in a form designated by the Company) together with this Grant Notice to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. (b) Upon exercising this Stock Appreciation Right, the Participant shall receive an amount equal to the Calculation of Appreciation for every stock appreciation right exercised. Until Shares are issued in respect of the exercise of this Stock Appreciation Right in accordance with the Plan, the Participant shall not have any of the rights or privileges of a shareholder of the Company in respect of any of the Shares covered by this Stock Appreciation Right. (c) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option, (2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. 8. TRANSFERABILITY. Your stock appreciation right is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your stock appreciation right. 9. STOCK APPRECIATION RIGHT NOT A SERVICE CONTRACT. Your stock appreciation right is not an employment or service contract, and nothing in your stock appreciation right shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your stock appreciation right shall obligate the Company or an Affiliate, their respective shareholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 10. WITHHOLDING OBLIGATIONS. (a) At the time you exercise your stock appreciation right, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of your stock appreciation right. (b) Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your stock appreciation right a number of whole shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid variable award accounting). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your stock appreciation right, share withholding pursuant to the preceding sentence shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the determination of such tax withholding obligation to the date of exercise of your stock appreciation right. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your stock appreciation right that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. (c) You may not exercise your stock appreciation right unless the tax withholding obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise your stock appreciation right when desired even though your stock appreciation right is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any escrow provided for herein unless such obligations are satisfied. 11. NOTICES. Any notices provided for in your stock appreciation right or the Plan shall be given in writing or shall be delivered electronically, and shall be deemed effectively given or delivered upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 12.

In the event of any conflict between the provisions of your stock appreciation right and those of the Plan, the provisions of the Plan shall control.

DIVIDENDS. You will be entitled to receive payments equal to any cash dividends and other distributions paid with respect to a corresponding number of shares subject to your Award, provided that any such dividends or distributions will be converted into additional shares covered by the Award (on the basis of the Fair Market Value of shares of Common Stock at the time of such dividend payment or other distribution), and further provided that such additional shares will be subject to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as apply to the other Restricted Stock Units and Common Stock subject to your Award. 4. PAYMENT. This Award was granted in consideration of your services to the Company. Subject to Section 10 below, you will not be required to make any payment to the Company (other than your past and future services with the Company) with respect to your receipt of the Award, vesting of the Restricted Stock Units, or the delivery of the shares of Common Stock subject to the Restricted Stock Units. 5.

This restriction on transfer will lapse upon delivery to you of shares of Common Stock in respect of your vested Restricted Stock Units. Your Award is not transferable, except by will or by the laws of descent and distribution. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to receive any distribution of shares of Common Stock in respect of vested Restricted Stock Units pursuant to this Agreement. 8.

You shall not have voting or any other rights as a shareholder of the Company with respect to the Common Stock acquired pursuant to this Agreement until such Common Stock is issued to you.
