ANNUAL MEETING OF SHAREHOLDERS
May 21, 2008

Introduction

        This proxy statement is furnished in connection with the solicitation of proxies for use at the 2008 annual meeting of shareholders of United Security Bancshares (also referred as to the "Company") to be held on Wednesday, May 21, 2008 at 7:00 p.m. at the Company's corporate offices at 2126 Inyo Street, Fresno, California, and at any and all adjournments thereof.

        It is anticipated that this proxy statement and the accompanying notice and form of proxy will be mailed on or about April 22, 2008 to shareholders eligible to receive notice of, and to vote at, the meeting.

Revocability of Proxies

        A form of proxy for voting your shares at the meeting is enclosed. Any shareholder who executes and delivers such proxy has the right to and may revoke it at any time before it is exercised by filing with the secretary of United Security Bancshares an instrument revoking it or a duly executed proxy bearing a later date. In addition, the powers of the proxyholders will be suspended if the person executing the proxy is present at the meeting and elects to vote in person by advising the chairman of the meeting of his or her election to vote in person, and voting in person at the meeting. Subject to such revocation or suspension, all shares represented by a properly executed proxy received in time for the meeting will be voted by the proxyholders in accordance with the instructions specified on the proxy. Unless otherwise directed in the accompanying proxy, the shares represented by your executed proxy will be voted "FOR" the nominees for election of directors named herein. If any other business is properly presented at the meeting, the proxy will be voted in accordance with the recommendations of United Security Bancshares' management.

Persons Making the Solicitation

        This solicitation of proxies is made by the board of directors of United Security Bancshares. The expense of preparing, assembling, printing and mailing this proxy statement and the materials used in the solicitation of proxies for the meeting will be borne by United Security Bancshares. It is contemplated that proxies will be solicited principally through the use of the mail, but directors, officers and employees of United Security Bancshares may solicit proxies personally or by telephone, without receiving special compensation.

Voting Securities

        There were issued and outstanding 11,833,566 shares of United Security Bancshares' common stock on March 28, 2008, which has been fixed as the record date for the purpose of determining shareholders entitled to notice of, and to vote at, the meeting. On any matter submitted to the vote of the shareholders, each holder of United Security Bancshares' common stock will be entitled to one vote, in person or by proxy, for each share of common stock he or she held of record on the books of United Security Bancshares as of the record date. In connection with the election of directors, shares may be voted cumulatively if a shareholder present at the meeting gives notice at the meeting, prior to the voting for election of directors, of his or her intention to vote cumulatively. If any shareholder of

1

---

United Security Bancshares gives such notice, then all shareholders eligible to vote will be entitled to cumulate their shares in voting for election of directors. Cumulative voting allows a shareholder to cast a number of votes equal to the number of shares held in his or her name as of the record date, multiplied by the number of directors to be elected. These votes may be cast for any one nominee, or may be distributed among as many nominees as the shareholder sees fit. If cumulative voting is declared at the meeting, votes represented by proxies delivered pursuant to this proxy statement may be cumulated in the discretion of the proxyholders, in accordance with management's recommendation. The effect of broker non-votes is that such votes are not counted as being voted; however such votes are counted for purposes of determining a quorum. The effect of a vote of abstention on any matter is that such vote is not counted as a vote for or against the matter, but is counted as an abstention.

Section 16(a) Beneficial Ownership Compliance

        Section 16(a) of the Securities Exchange Act of 1934 requires United Security Bancshares' directors and certain executive officers and persons who own more than ten percent of a registered class of United Security Bancshares' equity securities (collectively, the "Reporting Persons"), to file reports of ownership and changes in ownership with the Securities and Exchange Commission. The Reporting Persons are required by Securities and Exchange Commission regulation to furnish United Security Bancshares with copies of all Section 16(a) forms they file.

        Based solely on its review of the copies of such forms received by it, or written representations from the Reporting Persons that no Forms 4 or 5 were required for those persons, United Security Bancshares believes that, during 2007 the Reporting Persons complied with all filing requirements applicable to them, except Mr. Bitter, Mr. Braa, Mr. Miller and Mr. Terzian each inadvertently filed one Form 4 late.

The Board of Directors and Committees

        United Security Bancshares' board of directors met 12 times in 2007. None of United Security Bancshares' directors attended less than 75 percent of all board of directors' meetings and committee meetings of which they were a member. United Security Bancshares has a standing Audit Committee

Selection and Evaluation of Director Candidates

        The independent directors are responsible for identifying candidates for membership on the Board and makes determinations as to whether to recommend such candidates nomination to the Board based on their character, judgment, and business experience, as well as their ability to add to the Board's existing strengths. This assessment typically includes issues of expertise in industries important to United Security Bancshares, functional expertise in areas such as marketing, human resources, operations, finance and information technology and an assessment of an individual's abilities to work constructively with the existing Board and management, all in the context of an assessment of the perceived needs of the Board at that point in time. The independent directors do not have any written specific minimum qualifications or skill requirements that must be met by either their candidates or shareholder-recommended candidates in order to serve on the Board. The independent directors identify nominees by first evaluating the current members of the Board of Directors qualified and willing to continue in service. Current members of the Board with skills and experience that are relevant to United Security Bancshares' business and who are willing to continue in service are considered for renomination, balancing the value of continuity of service by existing members of the Board with that of obtaining a new perspective. If any member of the Board does not to wish to continue in service or if the independent directors or the Board decided not to nominate a member for reelection, the independent directors identify the desired skills and experience of a new nominee in light of the following criteria. When identifying and evaluating new directors, the independent directors consider the diversity and mix of the existing board of directors, including, but not limited to, such factors as: the age of the current directors, their geographic location (being a community bank, there is a strong preference for local directors), minority and female representation on the Board of Directors, employment experience, community representation, public interest considerations and the implementation of United Security Bancshares' strategic plan. Among other things, when examining a specific candidate's qualifications, the independent directors consider: the ability to represent the best interest of United Security Bancshares, existing relationships with United Security Bancshares, interest in the affairs of United Security Bancshares and its purpose, the ability to fulfill director responsibilities, leadership skill, reputation within United Security Bancshares' community, community service, integrity, business judgment, ability to develop business for United Security Bancshares and the ability to work as a member of a team. All nominees to be considered at the Meeting were recommended by the independent directors in executive session.

Communications with the Board and Annual Meeting Attendance

        Individuals who wish to communicate with United Security Bancshares's Board may do so by sending an e-mail to United Security Bancshares' Board at kbledsoe@unitedsecuritybank.com. Any communications intended for non-management directors should be sent to the e-mail address above to the attention of the Chairperson of the Audit Committee. United Security Bancshares does not have a policy regarding Board member attendance at annual meetings of shareholders. All of the then-directors of United Security Bancshares attended United Security Bancshares's 2007 annual meeting of shareholders.

Code of Ethics

        United Security Bancshares has adopted a Code of Business Conduct and Ethics that is applicable to the officers, directors and employees of United Security Bancshares. United Security Bancshares' principal executive officer, principal financial officer, principal accounting officer, controller, or persons performing similar functions also adhere to a Code of Ethics for Senior Financial Officers.

Audit Committee

        The Audit Committee met 10 times during the year ended December 31, 2007. During 2007, the Audit Committee of United Security Bancshares consisted of Directors Henry (chairman), Reinhard and Terzian. Director Henry is deemed by United Security Bancshares to be an "audit committee financial expert." Director Henry has an understanding of generally accepted auditing principles ("GAAP") and has the ability and experience to prepare, audit, evaluate and analyze financial statements which present the breadth and level of complexity of issues that United Security Bancshares reasonably expects to be raised by United Security Bancshares' financial statements. Director Henry is a Certified Public Accountant.

        The Audit Committee oversees United Security Bancshares' corporate accounting and reporting practices and the quality and integrity of United Security Bancshares' financial statements and reports, selects, hires, oversees and terminates United Security Bancshares' independent auditors, monitors United Security Bancshares' independent auditors' qualifications, independence and performance, monitors United Security Bancshares' and its affiliates' compliance with legal and regulatory requirements, and oversees all internal auditing functions and controls.

Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services of Independent Auditor

        The Audit Committee's policy is to preapprove all audit and nonaudit services provided by the independent auditors. These services may include audit services, audit-related services, tax services and other services. Preapproval is generally provided for up to one year and any preapproval is detailed as to particular service or category of services and is generally subject to a specific budget. The Audit Committee has delegated preapproval authority to its Chairman when expedition of services is necessary. The independent auditors and management are required to periodically report to the full Audit Committee regarding the extent of services provided by the independent auditors in accordance with this preapproval, and the fees for the services performed to date. The tax fees and other fees paid in 2007 and 2006 were approved per the Audit Committee's preapproval policies.

        The Audit Committee meets annually to discuss and review the overall audit plan. The Board has adopted a written charter for the Audit Committee which is available on United Security Bancshares' website at www.unitedsecuritybank.com .

Audit Committee Report

        This report of the Audit Committee shall not be deemed incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that United Security Bancshares specifically incorporates this information by reference, and shall not otherwise be deemed filed under the Acts.

        The Audit Committee has reviewed United Security Bancshares' audited financial statements and discussed such statements with management. The Audit Committee has discussed with Moss Adams LLP, United Security Bancshares' independent auditors during the year 2007, the matters required by Statement of Auditing Standards No. 61 (Communication with Audit and Finance Committees, as amended).

        The Audit Committee received written disclosures and a letter from Moss Adams LLP, required by Independence Standards Board Standard No. 1 and has discussed with them their independence from management. The Audit Committee has also considered whether the independent auditors' provision of other nonaudit services is compatible with the auditors' independence.

        Based on the review and discussions noted above, the Audit Committee recommended to the Board that United Security Bancshares' audited financial statements be included in United Security

Compensation Discussion and Analysis

Compensation Program Objectives

        The Company's Board of Directors established a Compensation Committee ("Committee") that is responsible for establishing and administering the Company's executive and director compensation. The Committee consists of only independent non-employee directors and operates under a formal written charter approved by the Committee and adopted by the Board.

        In this section, we discuss aspects of our compensation program as it pertains to our principal executive officer, our principal financial officer, and our three other most highly compensated executive officers in 2007. These individuals include all executive officers of the Company.

        The Committee believes that the performance of the named executive officers has the potential to impact both the Company's short-term and long-term profitability and stock performance. Therefore, the Committee places considerable importance on the design and administration of the executive compensation program.

        The policy of the Company is to provide its executive officers with total executive compensation packages that (a) attract and retain outstanding executives, (b) motivate and reward executives to achieve the Company's business objectives, and (c) align the interests of executive officers with the

9

---

long-term interests of the shareholders of the Company. More specifically to accomplish the aforementioned objectives, it is the policy of the Company to endeavor to provide each of its executive officers a total compensation package that is competitive with the marketplace and consistent with the overall performance of the Company.

        With respect to employment agreements, it is the policy of the Company to have a written employment agreement with the Chief Executive Officer. The terms of such employment agreements shall comply with the guidelines provided in our framework and not exceed a term of three (3) years. The Committee, in its discretion may offer employment agreements to other executive officers.

        The Committee believes that strong executive managers are critical to building a sound company that: produces consistent earnings growth and dividends for shareholders; develops and maintains well-designed banking products to attract and retain customers; and establishes a favorable working environment where employees can grow and excel in their careers. Currently, of the five members of executive management, four have served in their present capacities for more than a decade. The fifth, William F. Scarborough, was hired in 2005 to enhance the business development efforts of the Company.

        In the current California banking environment the number of new banks opening over the last five years) reduced the availability of experienced bankers and created a competitive market for human capital. Company executives are frequently contacted by recruiters and other individuals offering employment opportunities elsewhere. The Committee believes these conditions warrant considerable flexibility in compensation matters.

        The retention of executive management is the current active driver of the compensation program. As conditions change or vacancies occur in the future, the Committee may alter the executive compensation program to ensure it remains attractive and competitive for incumbent officers and potential candidates.

Elements of Compensation

        The compensation program is designed to reward executives' commensurate with Company performance relative to peers. The program is intended to reward executives through four primary components, salary, incentive compensation, stock options and a Supplemental Executive Retirement Plan (SERP).

        The Committee believes the program should encourage management to focus on all aspects and timeframes of the Company's evolution. The Committee reviews peer compensation programs and considers including similar elements of compensation where deemed appropriate in the Company's executive compensation program to ensure it remains competitive.

        The peer group selected was based upon asset size ($500 million to $1.3 billion) located in California. The peer group consisted of 18 publicly traded companies including some direct competitors. In evaluating the peer group, the Company's performance was generally higher than the peer average. More information on the peer group is shown below under the section titled How the Company Determines the Amount of Each Element of Compensation .

        Salary and incentive compensation are the short-term rewards that encourage strong earnings growth by rewarding executives in connection with peers and Company performance on a year-to-year basis. Stock options are the mid-term to long-term rewards and encourage management's focus on aspects like asset quality, expense control, consistent dividend and earnings growth over longer time frames. When those aspects, as well as others, are consistently performed well over longer time frames, the expected result is appreciation in stock price. Stock price appreciation is fundamental to realizing a compensation benefit from stock options. The SERP is the long-term component that rewards management for remaining with the Company over a period of several years.

        Currently, the compensation of each executive officer includes salary, incentive compensation tied to Company profits, stock options, retirement compensation (SERP) for a period of 15 years following retirement and group insurance premiums paid for spouse and eligible family members.

        Two executives, Dennis R. Woods and William F. Scarborough, hold options (50,000 and 60,000 respectively) to purchase shares that are 40% vested as of the date of filing of this document. The remaining executives have no remaining options.

Other Compensation to Our Executives

        With respect to perquisites, two executives, Dennis R. Woods and David L. Eytcheson, are provided with a Company owned vehicle. Mr. Woods purchased the memberships in two country clubs with his own funds and pays for any personal expenses incurred. The Company pays for business expenses incurred at the clubs as well as the membership dues.

        For all eligible employees, including executives, group insurance premiums for the employee are paid by the Company; the Company matches 401k employee contributions up to 5% of employee compensation (up to Federal compensation limits) and the Company funds an ESOP, generally at 8% of employee compensation (up to Federal compensation limits). Also, life insurance benefits equal to three times annual salary are provided to all employees except executives. The life insurance benefits provided to executives are fixed. The CEO's life insurance benefit is $750,000 and the life insurance benefit of each of the other four executive officers is $500,000. Additionally, the Company pays the costs of medical insurance for executive family members. Certain perquisites discussed later are offered principally to executive officers.

Determination of Compensation Amounts

General Overview

        Most Companies in the peer group offer the same components as the Company within executive compensation packages (salary, incentive compensation, stock options and SERP). The allocation or weight of those components varies. Most in the peer group grant options annually and offer larger SERP agreements than the Company. Most, if not all, grant annual salary increases. Some link incentive compensation to net income while others use return on equity or some other performance measurement. Under the Committee's compensation structure the weighting of the cash compensation components (salary plus incentive compensation) are generally larger than the stock options and SERP components, relative to peers. Unlike many in the peer group, the Committee grants salary increases and stock options infrequently rather than annually. The Committee believes the results of the Company are the best evidence that its executive compensation structure is effective. The Company's net income was in the 77th percentile and return on equity in the 95th percentile of the peer group for 2007.

Salaries

        The Committee determines the levels of the components of executive compensation after reviewing the peer and other data stated above under "Compensation Program Objectives." Outside consultants may be utilized to assist the Committee in the effort. Executive salaries are reviewed annually, but once established, typically are left unchanged for a few years. When salaries were last increased in January 2006, the Committee used subjective judgment as well as 2004 peer salary and performance data in its decision process. The Committee recognizes that without annual increases, Company executive salaries will drift below peer average salaries. The Committee practice of not granting annual salary increases and linking executive incentive compensation to Company net income, allows costs to move more in tandem with earnings and executives are more focused on growing net income, a prime component of

11

building shareholder value. The Committee left executive salaries unchanged in 2007 and will review salaries in 2008 when comparative data becomes available.

Incentive Compensation

        Incentive compensation is linked to net income for all five executive officers. This component of compensation in the Company is typically higher than peer incentive compensation because Company net income is typically higher than peer average net income and the Committee weights this component heaviest in the design of overall executive compensation. The Committee has determined subjectively that the CEO should earn incentive compensation equal to 4% of adjusted net income and the other four executive officers should each earn incentive compensation equal to 1% of adjusted net income. The determination to use a fixed percentage of net income (adjusted) for incentive compensation is reviewed annually by the Committee. Incentive compensation accruals are expensed each month throughout the year and net income includes the expense for each executive's incentive compensation. The amount of the after-tax expense accrual for each executive is added back to adjust net income for the percentage calculation of incentive compensation.

Stock Options

        The ownership of Company equity aligns the interests of executive officers with the long-term interests of shareholders. The policy of the Company is to provide executive officers with stock options to achieve the objective of aligning the interests of executive officers with the long-term interests of shareholders. The executive officers, by having a significant ownership interest of the Company, will be better aligned with the interests of the Company's shareholders. The stock option program may be utilized annually for executives. Historically, options granted at the time of employment as part of an initial compensation package and additional options added years later. With the exceptions of the newest executive who started in 2005 and Option's granted to the CEO in 2006 as part of his employment contract, no options have been granted to executives since 1997.

        The Committee, in making a determination to grant additional options, shall consider the total options already held by an executive officer, the date of last grant and the amount of stock options last granted, the number of shares of Company stock acquired through exercise of stock options sold by the executive officer and the percentage of Company stock ownership level held by the executive officer. Under the Company's compensation policy the Committee shall not make an annual option grant to an executive officer who had a new hire stock option grant within three (3) years of the hire date of such executive officer, and the Committee shall not make an annual option grant to an executive officer who owns less than three (3) times his or her annual base salary in Company stock (as measured by market value) as of the date of the expected grant.

Supplemental Executive Retirement Plan

        The SERP's have historically been awarded as part of the initial compensation package except with the original SERP awards, which were awarded after the executives had been employed for two or more years. The SERP of the CEO was awarded in June 1996 and is fully earned after June 2007 and can be drawn on by the CEO, if he retires, beginning June 2008. The CEO is entitled to compensation for 15 years at $100,000 per year under his SERP. The SERP's of the CFO, CCO and COO were awarded in January 1997 and are fully earned after January 1, 2008 and can be drawn on by the them, if they retire, beginning January 2009. They are entitled to compensation for 15 years at $50,000 per year under their SERP's. The SERP of the CBO was awarded in January 2006 and is fully earned after January 2017 and can be drawn on by the CBO, if he retires, beginning January 2018. The CBO is entitled to compensation for 15 years at $50,000 per year under his SERP.

12

---

        The Committee expects its executive officers to be long-term loyal leaders of the Company, and therefore should be provided with a supplemental executive retirement agreement ("SERP") as part of their total compensation package. A major condition of the payment of benefits is their long-term service with the Company. Therefore, vesting is set prorata for each year over the term of the SERP. Prior service credit for any newly hired executive is not permitted, except in the discretion of the Committee. The expected annual payment under the SERP shall not exceed 50% of the annual base salary of the executive officer at the time of entering into the SERP and the duration of such benefit payments shall not exceed fifteen (15) years after retirement. The Committee may increase the annual payment amount of the SERP to 50% of the annual base salary averaged over the last five years of the executive officer's employment with the Companies. The Committee may also approve a split dollar agreement related to the SERP of an executive officer, and determine the terms of such split dollar agreement including the treatment of imputed income of such split dollar agreement to the executive officer and any gross up of taxes associated with the imputed income. Prior to providing any SERP to an executive officer, the Committee shall have prepared and analyzed the accounting and tax effects of any SERP.

        The SERP's provide that benefits be paid to the executive officers' beneficiaries in the event of their deaths. The Company's obligation to pay begins in the month following death. The Company purchases single-premium life insurance policies for each SERP issued to protect the Company for this eventuality. The life insurance polices accrue tax-free income to the Company. The policies can remain in effect until the executive is deceased, even after all benefits under the SERP have been paid or can be liquidated at the option of the Company at the cash surrender value. The death benefit is designed to return to the Company, the cost of the SERP expense and cash value of the insurance carried on its books as an asset.

Change in Control Agreements

        The executive officers, excepting the CEO who has a change in control provision in his employment agreement, are covered by Change in Control Agreements ("CIC") last renewed in February 2008, for a period of five years. Under these agreements, the executives are entitled to receive compensation within 10 days of a change in control in a lump sum amount in cash equal to the sum of 12 months of the executive's then base salary and his or her bonus for the prior calendar year; provided however that such lump sum amount is reduced by the dollar amount necessary to allow the entire amount of such payment to be deductible for by the Company for purposes of Section 280G of the Internal Revenue Code.

        In 2006, the CEO entered into a new employment agreement with the Company that contained new change in control provisions effective February 2007. Under the agreement the CEO, upon a change in control receives severance benefits in a lump sum amount in cash equal to three times the average of the last three (3) years of the CEO's total compensation, inclusive of the CEO's base annual salary and all incentive compensation immediately following the date of completion of the change of control. Such severance benefits to the CEO are reduced to such amount that results in the greatest amount of the change in control payment that is deductible by the Company for federal income tax purposes after taking into account all other compensation payments to or for the benefit of the CEO that are included in determining the deductibility of such payments under Section 280G of the Internal Revenue Code. In the event that all other compensation payments to or for the benefit of CEO results in the limitation of the deductibility by the Company of severance benefits under Section 280G, then no severance benefits shall be made to the CEO pursuant to his employment agreement. The Committee believes these severance benefits to the executive officers are similar to the severance benefits offered by its peers and are necessary for the retention of the named executive officers and for the recruitment of new executive officers.

Other Benefits and Perquisites

        Group insurance premiums, including, medical, disability, dental and vision, are paid for by the Company for executive officers and their families. These benefits are common in most of the industry for similar positions. The Company pays these insurance benefits for all other employees and employees may elect to pay for the cost of insurance for their families. The 401k and ESOP are provided to all employees of the Company on the same basis and similar programs are offered by most of the industry. The CEO is provided with a Company owned vehicle along with membership dues for two country clubs. The COO is provided with a Company owned vehicle due to his job duties requiring extensive business travel. The Company has a corporate membership in a private restaurant, and each executive officer is authorized to utilize the membership for business purposes. The Company provides these perquisites to their named executive officers because these perquisites are offered by many of its peers, and therefore the Committee believes that providing these perquisites to the named executive officers is necessary for their retention and for the recruitment of new executive officers.

How the Company Determines the Amount of Each Element of Compensation

Salaries

        Executive officer salaries were last changed in January 2006. Prior to that date, the CEO salary was changed on November 1, 2000. The other executive officers received a salary increase in January 2006, January 2004 and November 2000. When executive salaries are adjusted, the Committee reviews average salaries of comparable peers along with peer performance data, such as, net income, return on equity, asset size, etc. The decision, to adjust salaries or not, is made after consideration of both peer group data and subjective judgment. For 2007, salaries were reviewed but no changes were made to executive salaries. For 2008, salaries are scheduled to be reviewed during the second quarter of 2008.

        The relationships of comparable peer group average executive salaries and incentive compensation are shown in the table below.

Executive Salaries and Incentive Compensation to Peer Comparison

peer 2006 compensation data was increased by 10% to provide for better comparison with 2007 United Security data

        Evident in the Executive Salaries and Incentive Compensation to Peer Comparison table above is that executive salaries for 2007 were generally lower than the 2006 average salaries (plus 10%) of peer executives, except for the CEO salary for 2007 at 24.6% over average peer CEO salaries (plus 10%) for 2006. The following Table lists the peers selected for comparison along with each company's 2007 Net Income, Return on Equity (ROE) and Year-End Assets. The Company's Net Income ($11.257 million) exceeded the peer group median ($6.726 million) by 67.4%, 2007 Return on Equity (15%) exceeded the peer group median (12.2%) by 24% and Year-End Assets ($772 million) exceeded the peer group median ($754 million) by about 2%.

Incentive Compensation

        The incentive compensation of the CEO is currently 4% of net income and the other executive officers incentive compensation is 1% of net income. It is the view of the Committee that linking incentive compensation of executives directly to shareholder net income is a highly effective means of incenting the executive team to grow earnings for shareholders.

        Calculation of final incentive compensation is made after the year-end financials have been completed, CPA reviewed and adjusted as the Committee determines appropriate. The incentive compensation calculation takes into account incentive compensation accruals passed during the year expensed from net income. The calculation for incentive compensation multiplies the percentage (4% or 1%) times the Company's reportable net income, tax effects that amount, adds the result to reportable net income and reapplies the incentive compensation percentage to adjusted net income to arrive at the final incentive compensation for each executive. The method adjusts net income for amounts expensed during the year to reflect the executive's incentive compensation prior to expensing that incentive compensation. The Committee may take into account the Company's asset quality and the condition of the Company's infrastructure (buildings, equipment, internal controls, compliance and other non-income generating departments) as an adjustment to any incentive compensation based on net income. In the event a restatement of net income becomes necessary, appropriate adjustments are made to the executive's incentive compensation in the year of restatement. Additionally, the Committee may take into account certain accounting conventions in the calculation of incentive compensation. During 2007 the Committee determined that two adjustments be made to net income prior to calculating incentive compensation; (i) under SFAS No. 157, Fair Value Measurements , the Company realized a fair value gain of $2.5 million related to its junior subordinated debt as a result of a refinance in July 2007 at rates now below market. The Committee determined the fair value gain

required by generally accepted accounting principles is not "true" income but rather accounting-convention-income that will vary over time depending on market conditions and eventually disappear at maturity of the debt instrument. As a result, $1.4 million ($2.5 million before income tax) was subtracted from the Company's net income prior to calculating incentive compensation for 2007; (ii) under SFAS No. 13, "Accounting for Leases", the Company previously recognized periodic rent expense as contractual rent payments became payable to the lessor, rather than on a straight-line basis throughout the life of the lease as required by SFAS No. 13. The difference in methodology was not previously considered material, but as the Company has grown, it was determined that adjustments should be made to properly comply with SFAS No. 13. The expense adjustment to record the difference between the contractual rental payment amounts and straight-line expense over the lease terms as applicable under SFAS No. 13 totaled $95,000 ($165,000 before income tax). As a result, $95,000 was added to the Company's net income prior to calculating incentive compensation.

Salary and Incentive Compensation

        Overall, as shown in Executive Salaries and Incentive Compensation to Peer Comparison table above, Company salaries and incentive compensation for 2007 are 124% to 87% of adjusted peer 2006 averages (plus 10%) for 2007. The Committee noted that the peer group median return on average equity for 2007 was 12.2% while the Company Return on Average Equity for 2007 was 15%. By this measurement, the Company exceeded the peer group by 24%. The Company's 2007 Net Income exceeded peer group median 2007 Net Income by 67.4%. The Committee determined that Company executive salaries and incentive compensation are at appropriate levels for 2007.

        The Committee recognizes that most companies grant stock options to executives annually and that most companies in the peer group provide more generous SERP agreements for executives than the Company. The Committee believes the structure of the Company's executive compensation program, with incentive compensation linked to Company net income, is very effective at incenting executives to grow income and subsequently, shareholder value.

        The following table sets forth the compensation paid or accrued during the last fiscal year to the Chief Executive Officer, the Chief Financial Officer and the three most highly compensated principal officers of the Company, whose total compensation during the last fiscal year exceeded $100,000.

The Role of Executive Officers in Determining Executive Compensation

        The Committee is responsible for obtaining information from management and the Board with respect to the performance of the Company in connection with review and finalization of incentive compensation payments each year. The CEO reviews the performance of the other named executive officers and provides recommendations to the Committee as to the adjustments to the other named executive officers' executive compensation. The Committee provides advice and consent to the CEO in his review and adjustment of other named executive officers' compensation. The final review and approval of the named executive officers' compensation resides with the Committee.

Tax Considerations

        It is the Committee's intent that all compensation be deductible by the Company, except as to change in control payments to executive officers that are considered excess parachute payments. In addition, Section 162(m) of the Internal Revenue Code imposes a $1 million limit on the tax deduction for certain executive compensation payments, though no named executive office had executive compensation under Section 162(m) that exceeded $1million in 2007.

Grants of Plan Based Awards

        No grants of plan-based awards were approved in 2007.

Stock Options

        The initial grant of stock options to executives has historically been at the time their employment commenced. The exercise price is the closing price of the Company stock on the date of grant. The date of grant is the date the Committee grants the option; however if the Committee grants the option effective as of a future grant date, the closing price on the future grant date is the exercise price for those options.

        The CEO was granted initial options to purchase 17,500 (210,000 adjusted for all stock splits) shares on 9/1/1994. The other executive officers, with the exception of the CBO, were granted options to purchase 10,000 (120,000 shares adjusted for all stock splits) shares at the time their employment with the Company commenced. The CBO was granted options of 30,000 (60,000 adjusted for all stock splits) shares at commencement of his employment on August 1, 2005.

        The number of initial options granted to each named executive officer followed the pattern established since the inception of the Company for the original executive officers, except that the original CEO had an initial option grant for 25, 000 (300,000 adjusted for all stock splits) shares and the current CEO's initial grant was for 17,500 (210,000 adjusted for all stock splits) shares.

        Subsequent to the initial option grants, the CEO was granted 17,500 (210,000 adjusted for all stock splits) additional options on 6/17/1996, 20,000 (120,000 adjusted for all stock splits) shares on 7/21/1997 and 25,000 (50,000 adjusted for the 2-for-1 stock split of May 1, 2006) shares on 2/6/2006. The other executive officers, with the exception of the CBO, were granted additional options of 10,000 (60,000 adjusted for all stock splits) shares on 7/21/1997.

Perquisites

        The CEO is permitted personal use of a Company owned automobile. Use of the automobile is provided for both business and personal use. The costs of a social membership in the San Joaquin Country Club and costs of membership in the Tehama Country Club are paid by the Company for the CEO. These memberships are primarily used for entertaining customers or potential customers but can be used for personal benefit at his discretion. These benefits are provided to the CEO primarily to ensure his total compensation package remains competitive with peers. The CEO also earns directors fees.

        The COO is permitted personal use of a Company owned automobile. This benefit is provided to the COO primarily because his duties include frequent visits to 11 branches of the Company. The Committee believes it is more equitable to the COO to provide him with a vehicle due to his job duties and such arrangement being more cost effective for the Company than mileage reimbursement at the allowed IRS rate.

        The named executive officers have health insurance coverage for their spouses and dependents with the premiums paid by the Company. The Company also pays the Medicare taxes on the benefits of SERP's that vest each year for each of the named executive officers.

401(k) and ESOP

        A component of Company's 401(k)/ESOP recognizes and rewards employee's contributions to its successful operation by enabling those employees to acquire a proprietary interest in United Security Bancshares' common stock. All employees of United Security Bank are eligible to participate in the 401(k) Plan upon the first day of the month after date of hire. Participants are automatically vested 100% in all employee contributions that they may invest in any of several authorized investment vehicles, including Company common stock. United Security Bank contributes funds to match the employee's 401(k) Plan contribution up to 5% of the employee's eligible annual compensation. These contributions are invested in Company stock and are subject to certain vesting requirements over a period of six years. Under the ESOP portion of the plan, the Company annually contributes shares of common stock for each eligible employee's account in an amount proportionate to the employee's compensation. The Company's contribution is at the discretion of the board of directors and has been 8% of employee compensation for all but two years since its inception in 1994 through 2007. In those two years the Company's contribution was 10% of employee compensation. Employees thereby have a vested interest in contributing on an ongoing basis to the profitability of the Company, and with a

23

vesting period of six years, they have the additional incentive to remain with United Security Bank on a long-term basis.

Executive Change in Control Agreements

        The Committee believes that change in control agreements are appropriate for its top executives because have contributed to the success of the Company, and therefore it is important to protect them in the event of a change in control.

        During 2008, the United Security Bank revised the Change in Control Agreements with executive officers, except for the CEO who has a change of control provision in his employment agreement. Under these agreements, the executives are entitled to receive a Change in Control Payment (as defined) within 10 days of a change in control a lump sum amount in cash equal to the sum of 12 months of the executive's then base salary and his or her bonus for the prior calendar year; provided however that such lump sum amount is reduced by the dollar amount necessary to allow the entire amount of such payment to be deductible for by the Company for purposes of Section 280G of the Internal Revenue Code.

        Effective January 1, 2007 and as revised in 2008, the CEO's current employment agreement contains the following change in control provisions.

        (A)  A change in ownership of the Company or the Bank occurs on the date that any person (or group of persons) acquires ownership of stock of the Company or the Bank that, together with stock held by such person or group, constitutes more than fifty percent (50%) of the total fair market value or total voting power of the stock of Company or the Bank, respectively.

        (B)  A change in effective control of Company or the Bank occurs on the date that: (i) any person (or group of persons) acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) ownership of stock of the Company or the Bank possessing thirty-five percent (35%) or more of the total voting power of the stock of the Company or the Bank, respectively; or (ii) a majority of members of the Company' or Bank's Board is replaced during any twelve (12) month period by directors whose appointment or election is not endorsed by a majority of the members of the Company's or the Bank's Board, respectively prior to the date of the appointment or election.

        (C)  A change in the ownership of a substantial portion of the Company' or the Bank's assets occurs on the date that any person (or group of persons) acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets from the Company or the Bank, respectively that have a total gross fair market value equal to, or more than, forty percent (40%) of the total gross fair market value of all of the assets of the Company or the Bank, respectively immediately prior to such acquisition or acquisitions. For the purposes of the Change in Control agreement, transfers of the outstanding voting securities of the Company or the Bank made on account of deaths or gifts, transfers between family members, former spouses or transfers to a qualified retirement plan maintained by the Company or the Bank shall not be considered in determining whether there has been a Change in Control.

        In the event of a Change of Control, the CEO shall be paid a lump sum amount in cash equal to three times the average of the last three (3) years of the CEO's total compensation, inclusive of the CEO's base annual salary and all incentive compensation immediately following the date of completion of the Change of Control. The Change of Control payment is reduced to such amount that results in the greatest amount of the Change in Control payment that is deductible by the Company for federal income tax purposes after taking into account all other compensation payments to or for the benefit of the CEO that are included in determining the deductibility of such payments under Section 280G of

24

---

the Code or any successor to Section 280G of the Code. In the event that all other compensation payments to or for the benefit of CEO results in the limitation of the deductibility by the Company of such payments under Section 280G or any successor to Section 280G of the Code, then no payment shall be made to the CEO pursuant to his Change in Control Agreement.

        The table below shows the maximum amounts that would be paid to the named executive officers under their respective agreements based on the executive's salary at December 31, 2007; and assumes the triggering event was December 31, 2007.

Director Compensation

        Director compensation is evaluated and recommended by the Committee and approved by the Board of Directors. Non-employee directors receive cash compensation for committee attendance, premiums for serving as chairs of certain committees, and equity grants in the form of stock options.

        During 2007, directors of United Security Bancshares and United Security Bank were compensated for monthly board meetings based on a performance rating structure ranging from a minimum of $800 per meeting up to $1,300 per meeting. In addition, the vice chairman received an additional $200 per meeting and the secretary received an additional $250 per meeting. Also, directors, other than Mr. Woods, were paid $200 for their attendance at committee meetings, other than loan committee meetings, and were paid $300 for their attendance at loan committee meetings, if such committee meeting was held on a day other than the regular board of directors' meeting. The chairman of the audit committee also received $400 per audit meeting and the chairman of the risk management committee received $300 per risk management meeting.

25

---

        Historically the non-employee Company directors have received equity compensation in the form of nonqualified stock options. The Committee selected this form of equity compensation because it aligned the interests of the Board of Directors to those of the shareholders and also because of accounting and tax treatments of such awards.

        The following table shows compensation paid or accrued for the last fiscal year to the Company's non-employee directors. Mr. Woods does not receive committee fees and his director meeting fees are disclosed.

        The following table sets forth information on director compensation:
