Dear Shareholder:

We are pleased to invite you to the Annual Meeting of Shareholders to be held
on Thursday, May 15, 2003, at 7:30 P.M. at the Rancho Santa Barbara
Marriott-Santa Ynez Valley, 555 McMurray Road, Buellton, California. As we have
done in the past, in addition to considering the matters described in the Proxy
Statement, we will review major developments since our last Shareholders'
Meeting.

We hope that you will attend the Meeting in person; however, we strongly
encourage you to designate the proxies named on the enclosed Proxy Card to vote
your shares. This will ensure that your common stock is represented at the
Meeting. For the first time, you will also be able to vote by telephone or by
the Internet. The Proxy Statement explains more about these voting procedures.
Please read it carefully. Please note that the shareholders of Mid-State Bank,
BSM Bancorp, City Commerce Bank and Americorp who have not yet surrendered
their shares to be exchanged into Mid-State Bancshares common stock must sign,
date and mail the proxy card in the postage paid envelope that we have provided
to you (telephone and Internet voting are not available to those unexchanged
holders).

We look forward to your participation.

By Order of the Board of Directors,

/s/ James G. Stathos

                                PROXY STATEMENT

     Your vote is very important. For this reason, the Board of Directors is
requesting that you allow your common stock to be represented at the annual
meeting by the proxies named on the enclosed proxy card. This proxy statement is
being sent to you in connection with this request and has been prepared for the
Board by our management. "We," "our," or "Mid-State" refer to Mid-State
Bancshares. The proxy statement is being sent to our shareholders on or about
April 15, 2003.

                     GENERAL INFORMATION ABOUT THE MEETING

     Who Can Vote. You are entitled to vote your Mid-State common stock if our
records showed that you held your shares as of March 31, 2003. At the close of
business on that date, a total of 23,488,310 shares of common stock were
outstanding and entitled to vote. Each share of Mid-State common stock has one
vote. The enclosed proxy card shows the number of shares that you are entitled
to vote. Your vote is confidential and will not be disclosed to persons other
than those recording the vote.

     Voting Your Proxy. If your common stock is held by a broker, bank, or other
nominee, you will receive instructions from them that you must follow in order
to have your shares voted.

     If you hold your shares in your own name as a holder of record, you may
instruct the proxies how to vote your common stock by using the toll free
telephone number or the Internet voting site listed on the proxy card or by
signing, dating, and mailing the proxy card in the postage paid envelope that we
have provided to you. Of course, you can always come to the meeting and vote
your shares in person. Specific instructions for using the telephone and
Internet voting systems are on the proxy card. The proxies will vote your shares
in accordance with those instructions. If you sign and return a proxy card
without giving specific voting instructions, your shares will be voted for the
election of directors named in this proxy statement.

     Matters to be Presented. We are not now aware of any matters to be
presented other than those described in this proxy statement. If any matters not
described in the proxy statement are properly presented at the meeting, the
proxies will use their own judgment to determine how to vote your shares. If the
meeting is adjourned, the proxies can vote your common stock on the new meeting
date as well, unless you have revoked your proxy instructions.


                                       1


     Revoking your Proxy. To revoke your proxy instructions if you are a holder
of record, you must advise the Secretary in writing before the proxies vote your
common stock at the meeting, deliver later proxy instructions, or attend the
meeting and vote your shares in person. Unless you decide to attend the meeting
and vote your shares in person after you have submitted voting instructions to
the proxies, we recommend that you revoke or amend your prior instructions in
the same way you initially gave them - that is, by telephone, Internet, or in
writing. This will help to ensure that your shares are voted the way you have
finally determined you wish them to be voted.

     How Votes are Counted. The annual meeting will be held if a majority of the
outstanding common stock entitled to vote is represented at the meeting. If you
have returned valid proxy instructions or attend the meeting in person, your
common stock will be counted for the purpose of determining whether there is a
quorum, even if you wish to abstain from voting on some or all matters
introduced at the meeting. If you hold your common stock through a nominee,
generally the nominee may vote the common stock that it holds for you only in
accordance with your instructions. Brokers who are members of the National
Association of Securities Dealers, Inc. may not vote shares held by them in a
nominee's name unless they are permitted to do so under applicable rules. Under
New York Stock Exchange rules, a member broker that has transmitted proxy
soliciting materials to a beneficial owner may vote on matters that the Exchange
has determined to be routine if the beneficial owner has not provided the broker
with voting instructions within 10 days of the meeting. If a nominee cannot vote
on a particular matter because it is not routine, there is a "broker non-vote"
on that matter. Broker non-votes count for quorum purposes, but we do not count
either abstentions or broker non-votes as votes for or against any proposal.

     Cost of this Proxy Solicitation. We will pay the cost of this proxy
solicitation. In addition to soliciting proxies by mail, we expect that a number
of our employees will solicit shareholders for the same type of proxy,
personally and by telephone. None of these employees will receive any additional
or special compensation for doing this. We will, on request, reimburse brokers,
banks, and other nominees for their expenses in sending proxy materials to their
customers who are beneficial owners and obtaining their voting instructions.

     Attending the Annual Meeting. If you are a holder of record and plan to
attend the annual meeting, please indicate this when you vote. The lower portion
of the proxy card is your admission ticket. If you are a beneficial owner of
common stock held by a broker, bank or other nominee, you will need proof of
ownership to be admitted to the meeting. A recent brokerage statement or a
letter from a bank or broker are examples of proof of ownership. If you want to
vote your common stock held in nominee name in person, you must get a written
proxy in your name from the broker, bank, or other nominee that holds your
shares.

                                  PROPOSAL 1
                             ELECTION OF DIRECTORS

     Our Bylaws and implementing resolutions provide for a total of ten (10)
directors. We have a "Classified" Board of Directors. A "Classified" Board means
that the directors are divided into three classes with staggered terms. As a
result, four (4) persons will be elected at the meeting to a term of three
years. At subsequent annual meetings of the shareholders, a number of directors
will be elected equal to the number of directors with terms expiring at that
annual meeting. The directors so elected at these subsequent annual meetings
will each be elected for a three-year term.

     Vote Required. Directors must be elected by a plurality of the votes cast
at the meeting. This means that the nominees receiving the greatest number of
votes will be elected. Votes withheld for any nominee will not be counted.

     Substitute Nominees. Although we know of no reason why any of the nominees
would not be able to serve, if any nominee is unavailable for election, the
proxies would vote your common stock to approve the election of any substitute
nominee proposed by the Board of Directors. We may also choose to reduce the
number of directors to be elected, as permitted by our Bylaws.

                      ABOUT THE BOARD AND ITS COMMITTEES

     The Board. Mid-State is governed by a Board of Directors and various
committees of the Board that meet throughout the year. Directors discharge their
responsibilities throughout the year at Board and committee meetings and also
through telephone contact and other communications with the Chairman and Chief
Executive Officer and others regarding matters of concern and interest to
Mid-State. During 2003, there were fifteen (15) meetings of the Board.

     Committees. Among other committees, Mid-State has audit, nominating and
corporate governance and compensation committees. The following describes for
each of these three committees its current membership, the number of meetings
held during 2002, and its function.

      Audit. Directors Snelling (Chairman), Bello and Flood.

     This Committee met six (6) times in 2002. Each member is "independent," as
defined by the Nasdaq listing standards. Pursuant to its Charter, the Audit
Committee is a standing committee appointed annually by the Board of Directors.
The Committee assists the Board of Directors in fulfilling its responsibility to
the shareholders and depositors relating to the quality and integrity of our
accounting systems and financial-reporting processes, the identification and
assessment of business risks and the adequacy of overall control environment
within Mid-State. In so doing, they will:

     o    Carry out their responsibilities in good faith and in an informed and
          vigilant manner;

     o    Review recommendations and reports submitted by the regulatory
          agencies, our external financial statement auditors, management, and
          Internal Audit;

     o    Routinely report to the Board of Directors, the Committee's activities
          and all matters of significance, making recommendations for change as
          deemed advisable;

     o    Establish and maintain contact with the regulatory agencies, the
          external financial statement auditors and Internal Audit to satisfy
          themselves that: audit coverage is adequate, appropriate programs are
          maintained, and activities are executed properly;

     o    Discuss directly with management any issues of concern or interest to
          the Committee; and

     o    Employ such resources in the performance of their duties, including
          access to separate legal counsel and external consultants, as the
          Committee deems necessary.

     A copy of the Audit Committee's Report for the year ended December 31, 2002
is attached as Appendix A to this proxy statement. The Audit Committee's Charter
was attached to our proxy statement for the 2001 meeting of shareholders. As
discussed below in "CORPORATE GOVERNANCE," the Charter is in the process of
being amended. We will attach the amended Charter to our proxy statement for the
2004 meeting of shareholders

     Nominating and Corporate Governance Committee. Directors Pruett (Chairman),
Lokey, Bello, Heron, Lagomarsino, Carey (Alternate Member), and Flood (Alternate
Member).

     This committee met one (1) time in 2002. The committee:

     o    Reviews information assembled for the purpose of selecting candidates
          for nomination to membership on the Board of Directors;

     o    Following appropriate investigations, ascertains the willingness of
          selected candidates to serve and extends on behalf of the Board of
          Directors, invitations to become candidates; and

     o    Presents recommendations to the Board of Directors at regularly
          scheduled meetings.

     Compensation. Directors Morris (Chairman), Bello, Carey, Heron, and
Snelling (Alternate Member)

     This committee met four (4) times in 2002. The committee:

     o    Establishes proper compensation ranges for officers and employees;

     o    Delegates certain authority to management regarding salary procedure;
          and

     o    Determines salaries for Mid-State officers depending upon experience,
          performance and contribution to the success of Mid-State.

     A copy of the Compensation Committee's Report for the year ended December
31, 2002 is attached as Appendix B to this proxy statement.

     Compensation Committee Interlocks and Insider Participation. No members of
the Compensation Committee were officers or employees of Mid-State or its
subsidiary during the year or were formerly Mid-State officers. The Chairman of
the Compensation Committee during 2002, Director Gregory R. Morris, is the
president and principal owner/stockholder of Morris & Garritano Insurance
Agency. Morris & Garritano received broker commissions during 2002 in connection
with the placement of insurance for Mid-State and its subsidiary. Such broker
commissions were less than 5% of Morris & Garritano's gross revenues for 2002.

                             CORPORATE GOVERNANCE

     We have a strong commitment to good corporate governance and to the highest
standards of ethical conduct.

     Corporate governance received a heightened degree of focus from our Board
of Directors and management during 2002. On July 30, 2002, President Bush signed
into law the Sarbanes-Oxley Act of 2002 (the "SOA"). The SOA includes very
specific additional disclosure requirements and new corporate governance rules,
requires the Securities and Exchange Commission (the "SEC") and securities
exchanges to adopt extensive additional disclosure, corporate governance and
other related rules and mandates further studies of certain issues by the SEC.
We have taken all required actions to comply with all the currently applicable
provisions of the SOA and implementing regulations. Additionally, we continue to
monitor regulations and rules proposed by the SEC and Nasdaq (our common stock
is listed on the Nasdaq national market) relating to these matters and to plan
for their implementation.

     During 2002, we took a series of steps to review and improve our existing
corporate governance practices. These steps included:

     o    A review of the composition of our Board of Directors to determine
          that we continue to have at least a majority of our directors that are
          independent, non-employee directors. We believe that at Mid-State Bank
          & Trust this has been the case since at least 1961 and has been the
          case for Mid-State Bancshares since it was formed in 1998.

     o    The nominating committee was combined and changed to the nominating
          and corporate governance committee. The committee, among other things,
          develops and recommends corporate governance principles applicable to
          Mid-State, including those concerning the size and composition of the
          Board, reviews potential candidates for board membership and
          recommends nominees to the Board.

     o    A review of our audit committee composition to assure that all current
          members meet both the existing as well as the proposed criteria for
          independence.

     o    The preparation of a draft of a revised audit committee charter which
          would, among other things, provide the committee with authority to (i)
          control directly the outside auditor, (ii) make hiring and termination
          decisions concerning the auditor, and (iii) approve all non-audit
          services. We expect that the revised charter will be adopted shortly
          after the completion of final rule making by the SEC and Nasdaq
          concerning these issues.


                                       9


     o    The adoption of a code of conduct for our Chief Executive Officer and
          Chief Financial Officer as required by the SOA. This code has been
          included as part of our corporate code of ethics which has been in
          place since at least 1997.

     o    Our Chief Executive Officer and Chief Financial Officer have begun
          certifying all quarterly and annual financial reports which we file
          with the SEC.

     o    We have completed a review of our internal controls and our disclosure
          controls and procedures to ensure that we provide complete and
          accurate disclosures in our SEC filings and other public reports. We
          merged our existing Risk Committee into a new Risk/Disclosure
          Committee. In addition to assessing various risks impacting Mid-State,
          this committee is made up of senior company officers knowledgeable of
          our affairs and of disclosure-related regulation. The committee is
          chaired by our chief financial officer and membership consists of our
          CEO, chief credit officer, corporate controller, and key senior
          members of Bank management. The committee convenes as necessary to
          review and decide upon the appropriate disclosure, if any, of
          potentially material events or change in the risk profile regarding
          Mid-State that come to the attention of any member of the committee,
          and to review and approve all earnings releases and other SEC filings,
          making sure that those filings are properly recorded, processed, and
          summarized. The committee seeks the advice of counsel and our
          independent audit firm in its deliberations.

     o    The implementation of a plan to post promptly our annual, quarterly
          and current reports to the SEC on our website at www.midstatebank.com.
          We have been posting some of these reports for sometime. We also
          anticipate beginning to post the ownership reports of our directors,
          executive officers and principal shareholders to the website,
          beginning in June 2003.

     o    During 2002, in conjunction with the change in accounting firms from
          Arthur Andersen LLP to PricewaterhouseCoopers LLP ("PWC"), the Company
          also considered several proposals to provide internal audit services.
          After review, the internal audit function was awarded to the firm,
          Protiviti, a risk management firm, independent from PWC.

                       COMPENSATION AND RELATED MATTERS

     Compensation. The compensation committee establishes the compensation
awarded to the executive officers, and determines the salaries of those
executive officers based upon their experience, performance, and contribution to
the success of Mid-State. The following table sets forth the aggregate
compensation for services in all capacities paid or accrued by Mid-State or its
banking subsidiary to the five (5) most highly compensated persons who earned
more than $100,000.00 in total salary and bonus during 2002.

     Stock Options. Our 1996 Stock Option Plan (the "Stock Option Plan") is
intended to advance our interests by encouraging stock ownership on the part of
key employees and non-employee directors. As of March 31, 2003, we had options
outstanding to purchase a total of 2,027,214 shares of our common stock under
the Stock Option Plan and 606,425 shares available for grant.

     The following table furnishes certain information regarding stock options
granted under the Stock Option Plan for James W. Lokey, James G. Stathos, Harry

     Profit Sharing/401(k) Plan. Mid-State offers a combined Profit Sharing and
401(k) Plan to all of its eligible employees, and those of its banking
subsidiary (the "Plan"). Eligible employees may participate in the Plan at the
next entry date following 90 days of service. Employer contributions to the
Profit Sharing and 401(k) Plan are vested on a five-year vesting schedule at 20%
per year.

     Contributions to the Profit Sharing portion of the Plan (the "Profit
Sharing Plan") are made entirely by Mid-State. Each year the Board of Directors,
in its discretion, decides how much money, if any, will be contributed to the
Plan depending on the amount of Mid-State's profits for the year. Mid-State's
contribution to the Profit Sharing Plan is allocated among all eligible
employees based on eligible pay. Employees must be actively employed at the end
of the calendar year in order to receive the profit sharing contribution. No
amounts are accrued or set aside for the account of non-employee directors.
Mid-State contributed approximately $1,659,000 to the Profit Sharing Plan for
the year ending December 31, 2002.

     Under the 401(k) portion of the Plan (the "401(k) Plan"), each covered
employee can make voluntary contributions to his or her account in an amount up
to fifteen percent (15%) of his or her base salary; such contributions vest
immediately when made. Mid-State makes a contribution to the employee's account
in an amount equal to fifty percent (50%) of the employee's contributions, up to
a maximum of six percent (6%) of the employee's salary. For the year ended
December 31, 2002, Mid-State contributed approximately $632,000 to the 401(k)
Plan.

- --------------------------
(50) Unexercisable stock options represent those options granted, but not yet
fully vested. Exercisable stock options represent the fully vested portion.
Stock options vest at the rate of 20% per year from the date of grant. Value of
options has been determined by multiplying number of shares by the difference
between the closing price on December 31, 2002 of $16.42 per share, and the
respective exercise price per share.


                                       13


     Change in Control Agreements. Mid-State entered into "change in control"
agreements with Messrs. Lokey, Sackrider, and Stathos as of January 9, 2002.
Each agreement provides that, if a person who has acquired control of Mid-State
terminates the officer within 36 months after such change in control other than
for cause, disability or retirement (as such terms are defined in the agreement)
or if, within 36 months of such a change in control, the officer terminates the
agreement for good reason (as defined in the agreement), the officer will
receive (i) a lump sum severance payment equal to three times his annual salary
and bonus and (ii) continued benefits under all insured and self-insured
employee welfare benefit plans for a period ending on the earliest of (A) three
(3) years, (B) the commencement date of equivalent benefits from a new employer
or (C) the officer's normal retirement date under the terms of such plans. In
general, a "change in control" includes a change in the majority of directors as
a result of an election contest, an acquisition of 25% of the outstanding
shares, a merger, consolidation, sale of substantially all the assets, a change
in the majority of directors over a two (2) year period as well as any other
transfer, voluntarily or by hostile takeover or proxy contest, operation of law
or otherwise, of control of Mid-State.

     Incentive Compensation Plan. In the first quarter of 2001, the Board of
Directors approved an annual Incentive Plan for the executive officers. The
objective of the plan is to provide competitive compensation, warranted by
performance, and aid in motivating and retaining key executives. Messrs Lokey,
Stathos and Sackrider are eligible for participation in the Plan.

     Other Compensation. We have provided and plan to continue to provide our
executive officers with automobiles, which are not available to all our
employees. It is impracticable to estimate the percentage of the total costs of
these benefits attributable to personal use. No amount is stated for the
foregoing in the compensation table on page 11, since management has concluded
that the amount of any personal benefits to any executive officer and to the
principal officers as a group is less than the lesser of $50,000.00 per person
or ten percent (10%) of the compensation reported under "Cash Compensation" for
each such person and for the group.

     Compensation of Directors. Directors who are also officers of the Company
do not receive additional compensation for their services as directors. During
2002, the Company's non-employee directors received a $12,000 annual retainer
and $1,000 for each regular and special meeting attended. The Chairman of the
Board received $1,500 for meetings attended. Members of the committees received
$300 for each committee meeting attended, while committee chairpersons received
$450 per meeting attended. Directors are also reimbursed for any out-of-pocket
expenses incurred during their duties as directors. Total fees paid to directors
in 2002 were $372,950.

     During 2002, Director Lagomarsino received a stock option grant under the
Stock Option Plan to purchase 20,000 shares of Mid-State Stock. The option was
granted at an exercise price of $15.95 per share, fully vested in five (5)
years, and are exercisable for ten (10) years.

     Transactions with Management and Others. There have been no transactions,
or series of similar transactions, during 2002, or any currently proposed
transaction, or series of similar transactions, to which Mid-State or its wholly
owned bank subsidiary was or is to be a party, in which the amount involved
exceeded or will exceed $60,000.00 and in which any director (or nominee for
director) of Mid-State, executive officer of Mid-State, any shareholder owning
of record or beneficially 5% or more of Mid-State Stock, or any member of the
immediate family of any of the foregoing persons, had, or will have, a direct or
indirect material interest.


                                       15


     Indebtedness of Management. Some of the current directors and executive
officers of Mid-State and the companies with which they are associated have been
customers of, and have had banking transactions with Mid-State, in the ordinary
course of Mid-State's business, and Mid-State expects to continue to have such
banking transactions in the future. All loans and commitments to lend included
in such transactions have been made on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for comparable
transactions with persons of similar creditworthiness, and in the opinion of
management of Mid-State, have not involved more than the normal risk of
repayment or presented any other unfavorable features.

     Section 16(a) of the Securities Exchange Act of 1934. Section 16(a) of the
Exchange Act requires Mid-State's directors, executive officers and ten percent
(10%) or more shareholders of Mid-State's equity securities to file with the SEC
initial reports of ownership and reports of changes of ownership of Mid-State's
equity securities. Officers, directors and ten percent (10%) or more
shareholders are required by SEC regulations to furnish Mid-State with copies of
all Section 16(a) forms they file. To Mid-State's knowledge, based solely on
review of the copies of such reports furnished to Mid-State and written
representations that no other reports were required, during the fiscal year
ended December 31, 2002 all Section 16(a) filing requirements applicable to its
executive officers, directors and beneficial owners of ten percent (10%) or more
of Mid-State's equity securities appear to have been met except, during the
transition period to electronic filings from the standard paper filings as
provided by SOA, there were several instances where the filings did not meet the
new requirements. In those cases, the reports were filed late with all necessary
disclosures.

                   RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS

     Background. On May 14, 2002, we terminated our engagement of Arthur
Andersen LLP ("Andersen") as our independent auditor. Andersen's report on our
financial statements for each of the years ended December 31, 2001 and 2000 did
not contain an adverse opinion or a disclaimer of opinion and was not qualified
or modified as to uncertainty, audit scope or accounting principles. With the
difficulties experienced by Andersen, the Audit Committee decided that it could
not retain its services in 2002. With the termination of our former independent
accounting firm, an extensive evaluation process was conducted by the Board of
Directors, the Audit Committee, and our management. We announced on July 12,
2002 the appointment of Pricewater-houseCoopers LLP ("PWC") as our new
independent accounting firm.

     It is anticipated that a representative of PWC will be present at the
meeting and will be available to respond to appropriate questions from
shareholders regarding the Company's financial statements.


                                       16


     Fees. All professional services rendered by PWC during 2002 were furnished
at customary rates and terms. For 2002, the Audit Committee considered and
deemed the services provided by PWC compatible with maintaining the principle
accountant's independence.

     The following table presents fees for professional audit services rendered
by PWC for the audit of our annual consolidated financial statements for the
fiscal year ended December 31, 2002, and fees billed for other services provided
by PWC during 2002.

                          REPORT OF THE AUDIT COMMITTEE

     The Audit Committee ("Committee") of the Board of Directors is composed of
three independent directors. The members of the Committee are: Directors
Snelling (Chairman), Bello and Flood.

     The Committee held six (6) meetings during 2002. During the course of the
year, the Committee reviewed drafts of a revised Audit Committee Charter which
would, among other things, provide the Committee with authority to (i) control
directly the outside auditor, (ii) make hiring and termination decisions
concerning the auditor, and (iii) approve all non-audit services. The Committee
expects that the revised Charter will be adopted shortly after the completion of
final rule making by the SEC and Nasdaq concerning these issues.

     The Committee oversees the financial reporting process for Mid-State
Bancshares ("Mid-State") on behalf of the Board of Directors. In fulfilling its
oversight responsibilities, the Committee reviewed the annual financial
statements to be included in the Annual Report and Form 10-K.

     In accordance with Statements on Accounting Standards (SAS) No. 61,
discussions were held with management and the independent auditors regarding the
acceptability and the quality of the accounting principles used in the reports.
These discussions included the clarity of the disclosures made therein, the
underlying estimates and assumptions used in the financial reporting, and the
reasonableness of the significant judgments and management decisions made in
developing the financial statements. In addition, the Committee has discussed
with the independent auditors their independence from Mid-State and its
management, including the matters in the written disclosures required by the
Independence Standards Board Standard No. 1.

     The Committee has also met and discussed with management and its
independent auditors, issues related to the overall scope and objectives of the
audit conducted, the internal controls used by Mid-State, and the selection of
Mid-State's independent auditors.

     Pursuant to the reviews and discussions described above, the Committee
recommended to the Board of Directors that the audited financial statements be
included in the Annual Report on Form 10-K for the fiscal year ended December
31, 2002.


                                       19

                                 APPENDIX "B"
                     REPORT OF THE COMPENSATION COMMITTEE
                    MID-STATE BANCSHARES AND MID-STATE BANK

     The goals of the Mid-State Executive Compensation Program (the "Program")
are to attract and retain higher caliber executives, provide compensation in a
cost efficient manner, encourage executive ownership of Mid-State Bancshares
("Mid-State") common stock and motivate executives to maximize returns to
shareholders, both annually and over the long-term.

     The philosophy of the Program is to provide a total reward program that
supports achievement of Mid-State's goals and objectives and provides total
compensation that is competitive in relation to that provided by comparable
financial institutions.

     Compensation for Mid-State's executive officers includes the following
components:

     o    Salary - The principal objective of the salary program is to maintain
          salaries that are targeted at the 75th percentile of the market for
          comparable positions in similarly sized financial institutions.

     o    Annual incentives - Annual incentives are designed to reward
          principally for overall annual Bank performance and provide total cash
          compensation that is targeted at the 75th percentile of the market
          when warranted by performance.

     o    Long-term incentives - The principal objective of the long-term
          stock-based incentive program is to align the financial interests of
          executives with those of shareholders, provide incentive for executive
          ownership of Mid-State common stock, support the achievement of
          long-term financial objectives, and provide for long-term incentive
          reward and capital accumulation opportunities.

     o    Benefits - The principal objectives of the benefits program provided
          for executives are to provide attractive benefits to retain key
          executives and provide financial planning opportunities to facilitate
          tax and estate planning.

CEO Compensation

In setting the Chief Executive Officer's (the "CEO") base salary and in
determining his performance bonus for fiscal 2002 the Compensation Committee
(the "Committee") has considered Mid-State's sustained revenue and profit growth
in recent years. In addition, the Bank continues to perform in the upper
quartile of the industry peer group. The CEO significantly contributed to this
success. Based on this performance, the Committee approved a salary increase and
cash bonus. The stock option grant made to the CEO was made at the fair market
value. All of the adjustments were made in accordance with the guidelines
established in the executive compensation plan.


                                       21


It is the opinion of the Committee that the aforementioned compensation policies
and structures provide the necessary discipline to properly align Mid-State's
corporate objectives and the interests of our shareholders with competitive
compensation practices in an equitable manner.

     Signed and adopted by the Compensation Committee this 18th day of February,
2003.
