PROXY STATEMENT/
PROSPECTUS

                        [BANK OF THE SIERRA LETTERHEAD]

                               April ___ , 2001


Dear Shareholder:

     You are cordially invited to attend the Annual Meeting of Shareholders of
Bank of the Sierra on Wednesday, May 23, 2001 at 7:30 p.m., to be held at our
Bank's Main Office, 90 North Main Street, Porterville, California 93257.

     Your Board of Directors has voted in favor of a reorganization creating a
bank holding company to be called Sierra Bancorp. Sierra Bancorp is a newly-
formed California corporation, organized at the direction of our Bank's Board of
Directors for the purpose of becoming a bank holding company. If shareholders
approve the reorganization, we will exchange each of your Bank of the Sierra
shares for one share of Sierra Bancorp. Thus, instead of owning Bank of the
Sierra directly, you will own shares in Sierra Bancorp which will own Bank of
the Sierra. After the reorganization you will have the same number of shares in
Sierra Bancorp as you currently have in Bank of the Sierra.

     Your stock in Sierra Bancorp will have a value equal to the value of your
stock in Bank of the Sierra and therefore the exchange will take place without
any recognition of gain or loss for federal income tax purposes. No changes in
Bank of the Sierra's directors, officers, or other personnel are contemplated as
a result of the formation of the bank holding company. Bank of the Sierra will
continue its present business and operations under its current name.

     The enclosed proxy statement/prospectus is also provided by the Board of
Directors in connection with the annual election of the Board of Directors of
Bank of the Sierra (all of whom are also directors of Sierra Bancorp). We are
pleased to enclose for your review this proxy statement/prospectus that provides
you with the information you need to evaluate the reorganization. We encourage
you to review it carefully.

     I strongly support the organization of Sierra Bancorp and enthusiastically
recommend that you vote in favor of it. Your interest and participation are
appreciated.

                                   Sincerely,


                                   James C. Holly
                                   President and Chief Executive Officer


     The reorganization involves risks.  SEE RISK FACTORS ON PAGE 5.

                QUESTIONS AND ANSWERS ABOUT THE REORGANIZATION


Q:  Why is this reorganization proposed?

A:  The Board of Directors of Bank of the Sierra believes that the bank holding
company structure will provide greater flexibility in terms of operations,
expansion, and diversification.

Q:  What will I receive in this reorganization?

A:  You will receive one share of Sierra Bancorp common stock for each share of
Bank of the Sierra common stock that you own immediately prior to the
reorganization.

Q:  How do I vote?

A:  Simply indicate on your proxy card how you want to vote and then sign and
mail your proxy card in the enclosed return envelope as soon as possible.  Your
Board of Directors unanimously recommends that you vote "FOR" the
reorganization.

Q:  If my shares are held in "street name" by my broker, will my broker vote my
shares for me?

A:  Your broker will not vote your shares for you unless you provide
instructions to your broker on how to vote.  It is important therefore that you
follow the directions provided by your broker regarding how to instruct your
broker to vote your shares.  If you fail to instruct your broker on how to vote
your shares, the effect will be the same as a vote against the reorganization.

Q:  Can I change my vote after I have mailed my signed proxy card?

A:  Yes.  You may change your vote at any time before your proxy is voted at the
annual meeting. If your shares are held in your name you may do this in one of
three ways. First, you may send a written notice stating that you would like to
revoke your proxy. Second, you may complete and submit a new proxy card. If you
choose either of these two methods, you must submit your notice of revocation or
your new proxy card to Bank of the Sierra's secretary. Third, you may attend the
meeting and vote in person. Simply attending Bank of the Sierra's annual
meeting, however, will not revoke your proxy. If you have instructed a broker to
vote your shares, you must follow directions received from your broker to change
your vote or to vote at Bank of the Sierra's annual meeting.

Q:  Should I send in my certificates now?

A:  No.  After the reorganization is completed, you will receive written
instructions for exchanging your stock certificates.

Q:  When do you expect this reorganization to be completed?

A:  We are currently working to complete the reorganization by the end of June,
2001.

Q:  Why have you sent this document and who can help answer my questions?

A:  This proxy statement/prospectus contains important information regarding
this proposed reorganization, as well as information about Bank of the Sierra
and Sierra Bancorp.  We urge you to read this proxy statement/prospectus
carefully, including its appendices.  You may also want to review the documents
listed under "WHERE CAN YOU FIND MORE INFORMATION" on page 38.  If you have more
questions about the reorganization, you should contact: Jack B. Buchold, Senior
Vice President and Chief Financial Officer, Bank of the Sierra, 86 North Main
Street, Porterville, California 93257, (559) 782-4900.

                                    SUMMARY

     This brief summary highlights selected information from this document and
does not contain all the information that is important to you.  We urge you to
read this proxy statement/prospectus carefully to fully understand the
reorganization.

Formation of a Bank Holding Company Which Will Own Bank of the Sierra

     The Board of Directors is asking you to vote on a proposal to organize a
bank holding company, Sierra Bancorp, which will own Bank of the Sierra.  The
new corporate structure will permit Sierra Bancorp and Bank of the Sierra
greater financial and corporate flexibility by giving us:

     .  increased structural alternatives for acquisitions;

     .  increased flexibility in acquiring or establishing other businesses
        related to banking;

     .  more alternatives for raising capital and access to debt markets; and

     .  greater flexibility regarding redemption of stock.

     We have attached the reorganization agreement as Appendix "A" at the back
of this proxy statement/prospectus.  We encourage you to read the reorganization
agreement, as it is the legal document that governs the transaction.

     In the reorganization, Bank of the Sierra will continue in its operations
as presently conducted under its management, but Bank of the Sierra will be a
wholly owned subsidiary of Sierra Bancorp.

The Companies

Sierra Bancorp

     Sierra Bancorp is not an operating company and has not engaged in any
significant business to date.  It was formed on November 16, 2000 as a
California corporation to be the holding company for Bank of the Sierra.  After
the reorganization, Sierra Bancorp will become a registered bank holding
company, whose principal asset will be its stockholdings in Bank of the Sierra.

     The address of Sierra Bancorp's and Bank of the Sierra's principal
executive offices is 86 North Main Street, Porterville, California 93257 and the
telephone number is (559) 782-4900.

Bank of the Sierra

     Bank of the Sierra is a California state-chartered bank which engages in
the commercial banking business.  Bank of the Sierra is headquartered in
Porterville, California and is the largest independent bank headquartered in the
South San Joaquin Valley with assets of approximately $607 million at December
31, 2000.  Bank of the Sierra operates sixteen branch offices in Tulare, Kern,
Kings and Fresno counties.

Sierra Merger Corporation

     Sierra Merger Corporation is a Delaware corporation newly organized as a
wholly-owned subsidiary of Sierra Bancorp in November, 2000.  Sierra Merger
Corporation's sole purpose is to merge into Bank of the Sierra in order to
facilitate the reorganization.  Sierra Merger Corporation will disappear after
the reorganization.

                                       2


The Management of Bank of the Sierra Will Continue After the Reorganization

     The directors and officers of Bank of the Sierra will continue to be
directors and officers of our Bank following the reorganization.  After the
reorganization, the present directors of Sierra Bancorp (who are also directors
of Bank of the Sierra) will continue to be directors of Sierra Bancorp, and
certain of the officers of Bank of the Sierra will also serve as officers of
Sierra Bancorp.  The shareholders of Sierra Bancorp will only elect the
directors of Sierra Bancorp after the reorganization.  Sierra Bancorp will elect
the directors of Bank of the Sierra.

We Need Your Approval

     In order to complete the reorganization, we need the approval of owners of
at least a majority of the outstanding shares of the common stock of Bank of the
Sierra.  As of March 26, 2001, the date on which a person must be a shareholder
to be entitled to vote, there were 9,212,280 shares of common stock outstanding
and entitled to vote.  Therefore, we will need the owners of 4,606,141 shares to
vote in favor of the reorganization.  The Board of Directors of Bank of the
Sierra unanimously recommends voting in favor of the reorganization.

The Directors and Executive Officers Intend to Vote in Favor of the
Reorganization

     Bank of the Sierra's directors and executive officers who beneficially
owned in the aggregate approximately 4,226,573 voting shares or 45.9% of the
outstanding shares of Bank of the Sierra common stock as of March 26, 2001,
intend to vote for the approval of the reorganization.

Shareholders Do Not Have Dissenters' Rights

     Bank of the Sierra's shareholders do not have dissenters' rights with
respect to the reorganization.

The Reorganization Will Be Tax-Free to You

     RSM McGladrey, Inc., which is affiliated with McGladrey & Pullen, LLP, Bank
of the Sierra's certified public accountants, has stated their opinion that no
gains or losses will be recognized by either Bank of the Sierra or Sierra
Bancorp or their shareholders as a result of the reorganization.   However,
because tax matters are complicated, and tax results may vary among
shareholders, we urge you to contact your own tax advisor to understand fully
how the reorganization will affect you.

Differences Between Bank of the Sierra and Sierra Bancorp

     Shareholders of Sierra Bancorp will have rights comparable to those rights
which they now possess as shareholders of Bank of the Sierra.  However, certain
minor differences will arise due to the fact that Sierra Bancorp is a non-bank
California corporation and Bank of the Sierra is a California state-chartered
bank subject to the provisions of the California Financial Code as well as the
California Corporations Code.  For a discussion regarding these differences, see
"BANK HOLDING COMPANY REORGANIZATION B Comparison of Rights of Shareholders of
Sierra Bancorp and  Bank of the Sierra."  There are also differences in the
availability of funds for the payment of dividends by Bank of the Sierra and
Sierra Bancorp.  (See "DIVIDENDS.")

Benefits to Directors and Officers of the Reorganization

     The reorganization will not provide any substantive benefits to directors
and officers of Bank of the Sierra, who will continue to be directors and
officers of Bank of the Sierra and Sierra Bancorp.

                                       3


Existing Options to Acquire Bank of the Sierra Common Stock Will Become Options
to Purchase Sierra Bancorp Common Stock After the Reorganization

     After the reorganization is completed all of the obligations of Bank of the
Sierra under Bank of the Sierra's 1998 Stock Option Plan will become obligations
of Sierra Bancorp on the same terms and conditions, with the exception that the
securities issued pursuant to Bank of the Sierra's 1998 Stock Option Plan will
be Sierra Bancorp common stock.

Accounting Treatment

     Because the proposed transaction is a reorganization with no change in
ownership interests, the consolidated financial statements of Sierra Bancorp and
Bank of the Sierra will retain the former bases of accounting of Bank of the
Sierra and will initially be identical to Bank of the Sierra's financial
statements prior to the reorganization.

Regulatory Approvals

     We cannot complete the reorganization unless it is approved or not
disapproved (as appropriate) by the Federal Reserve Board of San Francisco, the
FDIC and the California Department of Financial Institutions.

     Bank of the Sierra, Sierra Bancorp and Sierra Merger Corporation have filed
all of the required applications or notices with the above regulatory agencies.

     As of the date of this document, the Federal Reserve Board, the Department
of Financial Institutions and the FDIC have all issued the approvals or notices
of non-disapproval needed to consummate the reorganization, subject to certain
conditions.  While we do not know of any reason that we would not be able to
comply with any conditions, we cannot be certain that we will be able to meet
them.

Public Trading of Sierra Bancorp Stock

     Bank of the Sierra stock is listed for quotation on the Nasdaq National
Market under the trading symbol "BSRR" After the reorganization, Sierra Bancorp
stock will be listed for quotation on the National Market System and will use
the same trading symbol, "BSRR."

                                 RISK FACTORS

     In addition to the other information we provide in this proxy
statement/prospectus, you should carefully consider the following risks before
deciding whether to vote for the reorganization.

     Poor Economic Conditions May Cause Us to Incur Losses.  A substantial
majority of our assets and deposits are generated in the San Joaquin Valley in
central California.  As a result, poor economic conditions in the San Joaquin
Valley may cause us to incur losses associated with higher default rates and
decreased collateral values in our loan portfolio.  The San Joaquin Valley has
experienced a much slower economic recovery than other areas of the state of
California during the past year.  While the metropolitan centers and the Silicon
Valley have been characterized by dot-com euphoria and extensive job creation,
the central valley of California has not experienced the same type of growth.
Unemployment levels have remained high, especially in Tulare County, which is
our geographic center and the base of our agriculturally oriented communities.
In addition, in the early 1990s, the entire state of California experienced an
economic recession that resulted in increases in the level of delinquencies and
losses for many of the state's financial institutions.  If California were to
experience another recession, we expect that our level of problem assets would
increase accordingly.

     Poor Economic Conditions Affecting Particular Industries Could Have an
Adverse Effect on Our Customers and Their Ability to Make Payments to Us.  We
are also affected by certain industry-specific economic factors. For example, a
significant portion of our total loan portfolio is related to real estate
obligations (particularly home mortgage loans), and a portion of our recent
growth has been fueled by the general real estate recovery in California.
Accordingly, a downturn in the real estate industry in California could have an
adverse effect on our operations.  Similarly, a sizable portion of our total
loan portfolio is to borrowers in the agricultural industry.  While a great
number of our borrowers may not be individually involved in agriculture, many of
the jobs in the San Joaquin Valley are ancillary to the regular production,
processing, marketing and sales of agricultural commodities.  The ripple effect
of lower commodity prices for milk, olives, grapes, tree fruit and oranges has a
tendency to spread to lower land prices, lower borrower income, and lower
collateral values.  In addition, the weather patterns of the past two years have
not been conducive to row crop, tree fruit, or orange production.  This
degenerative cycle of weather and commodity prices then affects consumer
purchasing power, and creates further unemployment throughout the San Joaquin
Valley.  Such conditions may adversely affect our borrower base, and
consequently, may negatively impact our business.

     The California Energy Crisis May Adversely Impact Our Customers and May
Cause a General Downturn in the California Economy.  California has recently
experienced severe energy shortages which have resulted in "rolling blackouts"
in certain instances in portions of the state.  Rolling blackouts could cause
substantial disruptions and significant losses to our business customers,
including our significant base of borrowers in the agricultural industry who are
dependent on timely receipt of sufficient energy in connection with their
businesses.  Poor economic conditions as a result of energy shortages in the
agricultural industry or in other industries in the areas where our customers
are located could adversely affect our borrower base, and consequently, may
negatively impact our business.  In order to ensure future sources of energy for
California, it is anticipated that the prices paid by consumers for energy could
increase significantly.  Significant increases in energy prices could cause our
customers to experience losses or go out of business, which could result in
delinquencies and losses on loans made to our borrowers and in turn have a
material adverse effect on our business.  In addition, increases in the price of
energy as well as rolling blackouts could cause a general economic downturn in
the California economy, which could have a material adverse effect on our
financial condition and results of operations.

     We May Incur Risks As a Result of Our Growth.  Our Bank's total assets have
increased from $404 million at December 31, 1998, to $458 million at December
31, 1999 and to $607 million at December 31, 2000, or an increase of over 50% in
two years.  Our acquisition of Sierra National Bank in May 2000 increased our
Bank's  assets by approximately $87 million.  In addition, we intend to
investigate other opportunities to acquire or combine with additional financial
institutions that would complement our existing business as such opportunities
may arise. No assurance can be provided, however, that we will be able to
identify additional suitable acquisition targets or consummate any such
acquisition.

                                       5


     Our ability to manage our growth will depend primarily on our ability to:

     .  monitor operations;

     .  control costs;

     .  maintain positive customer relations; and

     .  attract, assimilate and retain qualified personnel.

     If we fail to achieve those objectives in an efficient and timely manner,
our financial condition and results of operations could be adversely affected.
Any such problems could adversely affect our existing operations, as well as our
ability to retain the customers of the acquired businesses or operate any such
businesses profitably.  In addition, such concerns may cause federal and state
banking regulators to require Sierra Bancorp or Bank of the Sierra to delay or
forgo any proposed acquisition until such problems have been addressed to the
satisfaction of those regulators.

     We have found that growth by acquisition is substantially different than
growth by de novo branch banking from both an operational and a cost standpoint.
Our assimilation of four operating units of Sierra National Bank in 2000 and the
concurrent demands of remodeling, upgrading electronic operating systems,
training the staff and eliminating wasteful activities required very different
skills than those involved in opening a new branch office. The fiscal effect of
adding four new branches in one year compared to the one or two per year we have
added in the past was to temporarily increase our overhead expenses as a
percentage of our total assets.  Further, the actions we took to correct
deferred maintenance, undocumented operating standards, organizational issues,
and a more narrow product line in these branches all contributed to additional
costs of operation.  The overall effect in 2000 was that our earnings were
reduced because of these increased costs.  Should we continue to grow by
acquisition, we expect to face similar increased costs in the future.

     Dividends in 2001 Will Be Lower Than in the Past Two Years and There is No
Assurance Sierra Bancorp Will Be Able to Pay Dividends.  We have recently
changed our dividend policy from paying quarterly cash dividends totaling at
least thirty-five percent (35%) of the prior year's net earnings (subject to
certain conditions) to paying cash dividends totaling between approximately
twenty percent (20%) and twenty-five percent (25%) of the prior year's net
earnings (subject to the same conditions).  In addition, the amount and timing
of the payment of dividends by Sierra Bancorp will be dependent on the earnings
and financial condition of Bank of the Sierra.  The power of Bank of Sierra's
Board of Directors to declare cash dividends is limited by statutory and
regulatory restrictions.  Although Sierra Bancorp anticipates continuing to pay
dividends in the future consistent with Bank of the Sierra's recently revised
dividend policy, no assurance can be given that Bank of the Sierra's and Sierra
Bancorp's future earnings in any given year will justify the payment of such a
dividend. (See "DIVIDENDS.")

     Changing Interest Rates May Reduce Our Net Interest Income.  Banking
companies' earnings depend largely on the relationship between the cost of
funds, primarily deposits and borrowings, and the yield on earning assets such
as loans and investment securities. This relationship, known as the interest
rate spread, is subject to fluctuation and is affected by economic, regulatory
and competitive factors which influence interest rates, the volume and mix of
interest-earning assets and interest-bearing liabilities, and the level of
nonperforming assets.  Many of these factors are beyond our control.
Fluctuations in interest rates affect the demand of customers for our products
and services.  Our bank is subject to interest rate risk to the degree that our
interest-bearing liabilities reprice or mature more slowly or more rapidly or on
a different basis than our interest-earning assets.  Given our current volume
and mix of interest-bearing liabilities and interest-earning assets, our
interest rate spread could be expected to increase during times of rising
interest rates and, conversely, to decline during times of falling interest
rates.  Therefore, significant fluctuations in interest rates may have an
adverse effect on our results of operations.

     Intense Competition Exists for Loans and Deposits.  The banking and
financial services business in California generally, and in our market area
specifically, is highly competitive.  The increasingly competitive environment
is a result primarily of changes in regulation, changes in technology and
product delivery systems and the accelerating pace of consolidation among
financial services providers.  We compete for loans, deposits and customers for
financial services with other commercial banks, savings and loan associations,
securities and brokerage

                                       6


companies, mortgage companies, insurance companies, finance companies, money
market funds, credit unions and other nonbank financial service providers. Many
of these competitors are much larger in total assets and capitalization, have
greater access to capital markets and offer a broader array of financial
services than we do. The reorganization will not, at least for the foreseeable
future, overcome these competitive disadvantages.

     You May Have Difficulty Selling Your Shares in the Future If a More Active
Trading Market for Our Stock Does Not Develop.  Although Bank of the Sierra's
Common Stock has been listed on the Nasdaq National Market since June, 1999,
trading in our stock has not been extensive and cannot be characterized as
amounting to an active trading market.

     Because the Price of Our Common Stock May Vary Widely, When You Decide to
Sell It, You May Encounter a Delay or Have to Accept a Reduced Price.  The price
of Sierra Bancorp common stock may fluctuate widely, depending on many factors.
Some of these factors have little to do with our operating results or the
intrinsic worth of our Bank or Sierra Bancorp.  For example, the market value of
Sierra Bancorp common stock may be affected by the trading volume of the shares,
announcements of expanded services by us or our competitors, operating results
of our competitors, general trends in the banking industry, general price and
volume fluctuations in the stock market, acquisition of related companies or
variations in quarterly operating results.  Also, if the trading market for our
common stock remains limited, that may exaggerate changes in market value,
leading to more price volatility than would occur in a more active trading
market.  As a result, if you want to sell your Sierra Bancorp common stock, you
may encounter delay or have to accept a reduced price.

     Sierra Bancorp's Stock Price May Fall if Bank of the Sierra has Poor
Earnings.  Sierra Bancorp's financial condition following the reorganization
will depend on the operation and profitability of Bank of the Sierra.  Sierra
Bancorp has no history of financial performance because it is a newly-formed
corporation.  Shareholders who receive Sierra Bancorp stock will not have the
opportunity to analyze the historical financial performance of Sierra Bancorp.
Sierra Bancorp's profitability may be affected by other factors including:
businesses started or acquired by Sierra Bancorp other than Bank of the Sierra;
and laws and regulations that apply to Sierra Bancorp.  Although Sierra Bancorp
intends to operate Bank of the Sierra in substantially the same manner that it
has been operated to date, changes to the operations of Bank of the Sierra and
new businesses may affect the financial performance and condition of Sierra
Bancorp as a whole and the return to shareholders of Sierra Bancorp.

     Adverse Effects of Banking Regulations or Changes in Banking Regulations
Could Adversely Affect Our Business.  We are governed by significant federal and
state regulation and supervision, which is primarily for the benefit and
protection of our customers and not for the benefit of our investors.  In the
past, our business has been materially affected by these regulations.  This
trend is likely to continue in the future. Laws, regulations or policies
currently affecting us and our subsidiaries may change at any time.  Regulatory
authorities may also change their interpretation of these statutes and
regulations.  Therefore, our business may be adversely affected by any future
changes in laws, regulations, policies or interpretations.

     Under a long-standing policy of the Federal Reserve Board, a bank holding
company is expected to act as a source of financial strength for its subsidiary
banks. As a result of that policy, we may be required to commit financial and
other resources to our subsidiary bank in circumstances where we might not
otherwise do so.

     Loan Loss Reserves May Not Cover Actual Loans Losses.  We maintain an
allowance for loan losses at a level which we believe is adequate to absorb any
inherent losses in our loan portfolio.  However, changes in economic, operating
and other conditions, including changes in interest rates, that are beyond our
control, may cause our actual loan losses to exceed our current allowance
estimates.  If the actual loan losses exceed the amount reserved, it will hurt
our business.  In addition, the FDIC and the Department of Financial
Institutions, as part of their supervisory functions, periodically review our
allowance for loan losses.  Such agencies may require us to increase our
provision for loan losses or to recognize further loan losses, based on their
judgments, which may be different from those of our  management.  Any increase
in the allowance for loan losses required by the FDIC or the Department of
Financial Institutions could also hurt our business.

                                       7


     We try to limit the risk that borrowers will fail to repay loans by
carefully underwriting the loans.  Losses nevertheless occur.  We create
reserves for estimated loan losses in our accounting records. We base these
allowances on estimates of the following:

     .  industry standards;

     .  historical experience with our loans;

     .  evaluation of current and predicted economic conditions;

     .  regular reviews of the quality mix and size of the overall loan
        portfolio;

     .  regular reviews of delinquencies; and

     .  the quality of the collateral underlying our loans.

     Our Directors and Executive Officers Control Almost a Majority of Our
Stock, and Your Interests May Not Always be the Same as Those of the Board and
Management.  As of December 31, 2000, our directors and executive officers
together with their affiliates, beneficially owned approximately 45.9% of Bank
of the Sierra's outstanding voting stock (not including vested option shares).
As a result, if all of these shareholders take a common position, they could
most likely control the outcome of most corporate actions, such as:

     .  approval of mergers or other business combinations;

     .  sales of all or substantially all of our assets;

     .  any matters submitted to a vote of our shareholders;

     .  issuance of any additional common stock or other equity securities;

     .  incurrence of debt other than in the ordinary course of business;

     .  the selection and tenure of our Chief Executive Officer; and

     .  payment of dividends on common stock or other equity securities.

     In some situations, the interests of our directors and executive officers
may be different from yours.  However, our Board of Directors and executive
officers have a fiduciary duty to act in the best interests of the shareholders,
rather than in their own best interests, when considering a proposed business
combination or any of these types of matters.

     Provisions in Our Articles of Incorporation Will Delay or Prevent Changes
in Control of Our Corporation or Our Management.  These provisions make it more
difficult for another company to acquire us, which could reduce the market price
of our common stock and the price that you receive if you sell your shares in
the future. These provisions include the following:

     .  a requirement that certain business combinations not approved by our
        Board of Directors receive the approval of two-thirds of the outstanding
        shares;

     .  staggered terms of office for members of the board of directors;

     .  the elimination of cumulative voting in the election of directors; and

     .  a requirement that our Board of Directors consider the potential social
        and economic effects on our employees, depositors, customers and the
        communities we serve as well as certain other factors, when evaluating a
        possible tender offer, merger or other acquisition of Bank of the Sierra
        or Sierra Bancorp.

     These provisions in Sierra Bancorp's Articles of Incorporation are
essentially identical to comparable provisions in Bank of the Sierra's Articles
of Incorporation which were approved by the shareholders in May, 2000.

                                       8

                   THE ANNUAL MEETING OF BANK OF THE SIERRA

General

     An annual meeting of the shareholders of Bank of the Sierra will be held at
Bank of the Sierra's Main Office, 90 North Main Street, Porterville, California
93257 on Wednesday, May 23, 2001 at 7:30 p.m.

     At the annual meeting, the holders of the common stock of Bank of the
Sierra will vote on:

     .  the election of four persons to serve as directors until the 2003 annual
        meeting;

     .  the approval of the principal terms of the reorganization; and

     .  such other business as may properly come before the annual meeting or
        any adjournments or postponements thereof.

Revocability of Proxies

     A proxy for use at the annual meeting is enclosed.  Any shareholder who
executes and delivers such proxy has the right to revoke it at any time before
it is exercised by filing with the Secretary of Bank of the Sierra an instrument
revoking it or a duly executed proxy bearing a later date, or by attending the
annual meeting and voting in person.  Subject to such revocation, all shares
represented by a properly executed proxy received in time for the annual meeting
will be voted by the proxy holders whose names are set forth in the accompanying
proxy in accordance with the instructions on the proxy.  If no instruction is
specified with respect to a matter to be acted upon, the shares represented by
the proxy will be voted in favor of (i) the election of the nominees for
directors set forth herein, (ii) the approval of the bank holding company
reorganization and, if any other business is properly presented at the annual
meeting, in accordance with the recommendations of your Board of Directors.

Solicitation of Proxies

     Bank of the Sierra will bear the cost of this solicitation, including the
expense of preparing, assembling, printing and mailing this proxy
statement/prospectus and the material used in this solicitation of proxies. The
proxies will be solicited principally through the mails, but Bank of the
Sierra's directors, officers and regular employees may solicit proxies
personally or by telephone.  Arrangements will be made with brokerage firms and
other custodians, nominees and fiduciaries to forward these proxy solicitation
materials to shareholders whose Bank of the Sierra stock  is held of record by
such entities, and Bank of the Sierra will reimburse such brokerage firms,
custodians, nominees and fiduciaries for reasonable out-of-pocket expenses
incurred by them in connection therewith.  In addition, we may pay for and
utilize the services of individuals or companies we do not regularly employ in
connection with the solicitation of proxies.


                               VOTING SECURITIES

     There were issued and outstanding 9,212,280 shares of Bank of the Sierra's
common stock on March 26, 2001, which has been set as the record date for the
purpose of determining the shareholders entitled to notice of and to vote at the
Meeting.  The presence, in person or by proxy, of at least a majority of the
total number of outstanding shares of the Common Stock is necessary to
constitute a quorum at the Meeting for the transaction of business.  Abstentions
and broker non-votes are each included in the determination of the number of
shares present for determining a quorum but are not counted on any matters
brought before the Meeting.

     Each holder of common stock will be entitled to one vote, in person or by
proxy, for each share of common stock standing in his or her name on the books
of Bank of the Sierra as of March 26, 2001 for the annual meeting on any matter
submitted to the vote of the shareholders.  An abstention or broker non-vote
will have the same effect as

                                       10


a vote against a director nominee and against any other matters submitted for
shareholder approval. Shareholders of Bank of the Sierra do not have cumulative
voting rights in connection with the election of directors.

                SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS

     Management knows of no person who owned beneficially more than five percent
(5%) of the outstanding Common Stock of Bank of the Sierra as of March 26, 2001,
except for Gregory A. Childress, Robert L. Fields, James C. Holly and Morris A.
Tharp, each of whom is a member of Bank of the Sierra's Board of Directors (see
"PROPOSAL 1 - ELECTION OF DIRECTORS - Information Concerning Directors, Nominees
and Executive Officers").


                                  PROPOSAL 1

                             ELECTION OF DIRECTORS

     The Bylaws of Bank of the Sierra provide that the number of directors shall
be not fewer than six (6) nor more than eleven (11) until changed by a bylaw
amendment duly adopted by the vote or written consent of the shareholders. The
Bylaws further provide that the exact number of directors shall be fixed from
time to time, within the foregoing range, by a bylaw or amendment thereof or by
a resolution duly adopted by the vote or written consent of the shareholders or
by the Board of Directors. The exact number of directors is presently fixed at
nine (9).

     In May, 2000, the shareholders approved an amendment to Bank of the
Sierra's Articles of Incorporation providing for two classes of directors, each
serving terms of two years. Five of the directors elected at the 2000 Annual
Meeting of Shareholders were elected for a two year term and the remaining four
directors were elected for a one year term. At this year's annual meeting, only
the four directors whose terms expire this year will be elected.

     Since shareholders do not have cumulative voting rights in the election of
directors, the affirmative vote of a plurality of the votes cast is required for
the election of directors. In the event that any of the nominees should be
unable to serve as a director, it is intended that the Proxy will be voted for
the election of such substitute nominee, if any, as shall be designated by the
Board of Directors. Management has no reason to believe that any nominee will
become unavailable.

     Your Board of Directors unanimously recommends a vote of "AUTHORITY GIVEN"
to elect all of the nominees for director of Bank of the Sierra.

                                       11


Information Concerning Directors, Nominees and Executive Officers

     The following table sets forth certain information as of March 26,
2001, with respect to (i) each of the persons to be nominated by the Board of

Committees of the Board of Directors

     Bank of the Sierra has, among others, a standing Audit/CRA Committee, of
which directors Berra (Chairman), Childress, Fields, Jurkovich and Tienken are
members.  During the fiscal year ended December 31, 2000, the Audit/CRA
Committee held a total of twelve (12) meetings.  The purpose of the Audit/CRA
Committee, with respect to its audit duties, is to meet with the outside
auditors of Bank of the Sierra in order to fulfill the legal and technical
requirements necessary to adequately protect the directors, shareholders,
employees and depositors of Bank of the Sierra.  It is also the responsibility
of the Audit/CRA Committee to recommend to the Board of Directors the selection
of independent accountants and to make certain that the independent accountants
have the necessary freedom

and independence to freely examine all bank records. Each February the committee
reviews the risk management assessment of Bank of the Sierra's branches, credit
centers and operating units and assigns priorities for the year to have
independent reviews conducted by loan, operational, information systems and
compliance teams hired by the committee. The committee meets with such
independent review consultants on an annual basis and approves the contractual
basis of each engagement letter and arrangement under consideration. Further, as
part of its regular monthly meeting schedule, the committee meets on a quarterly
basis to review our Bank's Form 10-Q with the independent accountants prior to
such Form being filed with appropriate agencies. Also, the committee meets with
the accounting audit partner in charge of the engagement who presents the
audited consolidated financial reports to the committee upon completion of the
annual engagement. The committee receives and reviews management letters and all
reports of external independent firms which have been contracted to perform
agreed upon procedures for the benefit of Bank of the Sierra and the Committee.
Additionally, the committee receives and reviews all Reports of Examination
prepared by regulators regarding safety and soundness, compliance, or other
examinations performed by such agencies. As part of its responsibilities, the
committee also receives, reviews and approves, any and all management initiated
responses to engagements conducted by independent consultant firms or regulatory
agencies, prior to their dispersal to the appropriate reviewing agent. The Audit
Committee Charter (attached as Appendix "B") requires that the Audit Committee
be comprised of at least three directors, each of whom must be independent.

     While the Board has no standing "compensation" committee, it has a
Personnel Committee of which directors Berra (Chairman), Fields, Smith and Woods
are members. The primary function of the Personnel Committee, which met two (2)
times during 2000, is to approve the employment of executive officers and
recommend the compensation for all executive officers. Additionally, the
Personnel Committee recommends salary ranges for graded personnel and approves
personnel policies recommended by senior officers of Bank of the Sierra.

     Bank of the Sierra has no standing nominating committee; however, the
procedures for nominating directors, other than by the Board of Directors
itself, are set forth in Bank of the Sierra's Bylaws and in the Notice of Annual
Meeting of Shareholders.

     During the fiscal year ended December 31, 2000, the Board of Directors of
Bank of the Sierra held a total of fourteen (14) meetings. Each director
attended at least 75% of the aggregate of (a) the total number of such meetings
and (b) the total number of meetings held by all committees of the Board on
which such director served during 2000.

Report of the Audit Committee

     The Audit/CRA Committee has reviewed and discussed with management Bank of
the Sierra's audited consolidated financial statements as of and for the year
ended December 31, 2000. The committee has discussed with Bank of the Sierra's
independent auditors, which are responsible for expressing an opinion on the
conformity of Bank of the Sierra's audited consolidated financial statements
with generally accepted accounting principles, the matters required to be
discussed by Statement on Auditing Standards No. 61, as amended, including their
judgments as to the quality of Bank of the Sierra's financial reporting. The
committee has received from the independent auditors written disclosures and a
letter as required by the Independence Standards Board, Standard No. 1, as
amended, and discussed with the independent auditors the firm's independence
from management and Bank of the Sierra. In considering the independence of Bank
of the Sierra's independent auditors, the committee took into consideration the
amount and nature of the fees paid the firm for non-audit services, as described
on page 37 below.

     In reliance on the review and discussions described above, the committee
recommends to the Board of Directors that the year-end audited consolidated
financial statements be included in Bank of the Sierra's Annual Report on Form
10-K for the year ended December 31, 2000 for filing with the FDIC.

however, that if an optionee fails to exercise his or her rights under the
options within the year such rights arise, the optionee may accumulate them and
exercise the same at any time thereafter during the term of the option. In
addition, in the event of a "Terminating Event," i.e., a merger or consolidation

Compensation of Directors

     Non-employee directors of Bank of the Sierra received $400 per month for
their attendance at regular Board meetings in 2000, $225 per meeting for their
attendance at special Board meetings, and between $150 and $250 per committee
meeting, depending upon the particular committee involved. The President
received $400 per month for attendance at regular Board of Directors meetings
(and $225 for attendance at the organizational Board meeting), but did not
receive special Board or committee meeting fees.  In addition, all directors

Performance Graph

     The following graph compares the yearly percentage change in Bank of the
Sierra's cumulative total shareholders' return on Bank of the Sierra's stock
with the cumulative total return of (i) the Nasdaq market index; (ii) all banks
and bank holding companies listed on Nasdaq; (iii) an index comprised of banks
and bank holding companies headquartered in the western United States; and (iv)
an index comprised of banks and bank holding companies located throughout the
United States with total assets of between $250 and $500 million.  The latter
two peer group indexes were compiled by SNL Securities LP of Charlottesville,
Virginia.  Bank of the Sierra reasonably believes that the members of the fourth
group listed above  constitute peer issuers for the period from January 1, 1996
through December  31, 2000.  The graph assumes an initial investment of $100 and
reinvestment of dividends.  The graph is not necessarily indicative of future

Board of Directors' Compensation Committee Report

     The Personnel Committee of the Board is responsible for overseeing the
various compensation programs of the Bank.  It approves compensation objectives
and policy for all employees and sets compensation levels for the Bank's
Executive Officers.  During 1999, the Personnel Committee was comprised entirely
of independent outside directors, namely, directors Berra (Chairman), Fields,
Smith and Woods.  In addition, director Holly (President and Chief Executive
Officer of the Bank) is an ex-officio member of this Committee.

     The objectives of the Committee are three-fold; (i) to ensure that
compensation and benefits are at levels that enable the Bank to attract and
retain the high quality employees it needs; (ii) to align the interests of the
Bank's officer corps with those of its stockholders through at risk compensation
programs; and (iii) to provide rewards that are closely linked to Bank-wide team
and individual performance goals which are measured in terms of the Bank's
profitability, growth and asset quality.

     Executive officer base salaries are fixed for a three-year term.  Executive
Officer bonuses are awarded annually and are determined with reference to Bank-
wide team and individual performance.  Base salaries are determined on a wide
range of measures which require comparisons with salaries and compensation
programs at banks comparable in terms of asset size, capitalization and
performance.  In order to evaluate the Bank's competitive position in the
industry, the Personnel Committee reviews and analyzes the compensation
packages, including base salary levels offered by community banks, specifically
reviewing the annual survey prepared by the California Department of Financial
Institutions, and that prepared for the California Bankers Association by
Deloitte and Touche, C.P.A.'s.  The Bank's practice, however, is not to provide
employment contracts to any executive officers as all employees of the Bank are
employed at will.

     Salaries are fixed for Executive Officers; however, bonuses are dependent
on the achievement by the Bank of annual profitability goals and specific
performance goals.  In 1998, the Board implemented a three-year incentive plan
for Bank officers.  The President is specifically excluded from this plan to
enable him to objectively administer the plan; his bonus is determined by a
separate plan related solely to Bank profitability and base salary.  All other
officers are eligible for incentive bonuses based upon the attainment of certain
corporate performance goals related to both pre-tax earnings and after-tax
return on equity, thereby reflecting favorably upon enhanced stockholder return.
Under this plan, a formula was developed which created a pool from which
incentive bonuses would be allocated to eligible officers.  The earnings
targets, as well as the corporate performance goals, are based on confidential
information and are competitively sensitive to the Bank as they are derived from
the Bank's internal projections and business plan.  The distribution of the pool
is based on the level of the participant, with the eligible Executive Officers
receiving up to a maximum of 40% of base salary and less senior officers
receiving lesser percentages.  The amounts paid to the Named Executive Officers
pursuant to these incentive plans are listed in the Summary Compensation Table
above (see "Executive Compensation" herein).

     In order to (i) provide an additional incentive for the Bank's officers and
employees to contribute to the Bank's success,  (ii) encourage their increased
stock ownership in the Bank, and (iii) enable the Bank to be competitive in the
industry with respect to compensation packages, the Board of Directors adopted a
Stock Option Plan (the "Option Plan") in 1998.  Details concerning the Option
Plan and options granted thereunder to the Named Executive Officers are set
forth above under "Stock Options."

                             Personnel Committee:

                           Albert L. Berra, Chairman
              Robert L. Fields                  Gordon T. Woods

Transactions with Directors and Executive Officers

     Certain of the executive officers, directors and principal shareholders of
Bank of the Sierra and the companies with which they are associated have been
customers of, and have had banking transactions with, Bank of the Sierra in the
ordinary course of Bank of the Sierra's business since January 1, 2000, and Bank
of the Sierra 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
other persons of similar creditworthiness, and in the opinion of Management,
have not involved more than the normal risk of repayment or presented any other
unfavorable features.


                                  PROPOSAL 2

                      BANK HOLDING COMPANY REORGANIZATION

     The Board of Directors of Bank of the Sierra has approved a plan of
reorganization under which the business of Bank of the Sierra will be conducted
as a wholly-owned subsidiary of Sierra Bancorp and each outstanding share of
Bank of the Sierra's common stock will be converted into one share of Sierra
Bancorp's Common Stock.  The details of the reorganization are set forth in the
Plan of Reorganization and Agreement of Merger among Bank of the Sierra, Sierra
Bancorp and Sierra Merger Corporation which is attached as Exhibit "A" hereto.
Your Board of Directors has unanimously approved the reorganization agreement
and recommends a vote "FOR" the proposed reorganization.

Reasons for the Reorganization

     We believe that a holding company structure will better position us to
compete in the markets that we serve by providing greater corporate and
financial flexibility in conducting our business.  Examples are:

     .    increased structural alternatives for acquisitions;

     .    increased flexibility in acquiring or establishing other businesses
          related to banking;

     .    more alternatives for raising capital and access to debt markets; and

     .    greater flexibility regarding redemption of stock.

     The bank and thrift industry has been undergoing a period of consolidation
for some time.  We believe that the holding company structure may make it easier
for us to respond quickly to take advantage of expansion opportunities which are
in our shareholders' best interests.  For instance, as a bank, we cannot own a
separate bank or thrift institution, but Sierra Bancorp could acquire and
operate another institution as a separate entity.  This might be a good
alternative if we wanted to expand into geographic markets where the continued
use of an existing bank's local name or identity would be desirable.  Also,
holding companies can acquire effective control of other banks by purchasing
substantially less than 100% of the target bank, which is considerably cheaper
than acquisitions by banks, which must involve 100%.  Acquisitions by holding
companies may also enjoy certain tax and/or accounting-related advantages
regarding acquisition premiums and/or acquisition debt, although no assurance
can be given that such advantages will continue to apply in the future.

     The reorganization may also make it easier for us to engage in certain non-
bank activities and to take advantage of future changes in the laws and
regulations governing banks and bank-related activities.  For example, since
1997, there has been a significant expansion of permissible non-banking
activities for bank holding companies and subsidiaries thereof in a wide variety
of areas.  While an adequately capitalized  state bank would be permitted to

engage in these activities, it would generally not be able to invest in the
------                                                        ------
stock of other corporations that engage in such activities (other than majority
owned subsidiaries).  In addition, while there can be no guarantee that this
will happen,

                                       19


opportunities may arise in the future for bank holding companies which would not
be available to banks. The bank holding company corporate structure may prove
valuable in taking advantage of any such new opportunities that may be made
available in the future.

     The reorganization may also enable us to take advantage of certain
provisions of the Gramm-Leach-Bliley Act which, effective March 11, 2000,
eliminated most barriers to affiliations among banks and securities firms,
insurance companies, and other financial service providers, and enabled full
affiliations to occur between such entities.  This new legislation permits
qualified bank holding companies to become "financial holding companies" and
thereby acquire securities firms and insurance companies and engage in other
activities that are financial in nature.

     The holding company structure would also provide greater flexibility in the
area of repurchase of securities.  Currently, we are permitted to repurchase our
stock, but only with the prior approval of both the Department of Financial
Institutions and the FDIC, and subject to applicable restrictions and
requirements imposed by both agencies.  Sierra Bancorp, on the other hand, would
be permitted to repurchase its stock by action of the Board of Directors,
subject to any limitations imposed by the rules and regulations of the Federal
Reserve Board and the limitations on dividends under applicable state law.
Current policies of the Federal Reserve Board would require Sierra Bancorp to
notify the Federal Reserve Board of any proposed repurchase which (including all
purchases or redemptions of its equity securities during the 12 months preceding
the date of notification) would equal or exceed 10% of Sierra Bancorp's
consolidated net worth as of the date of such notice.  Repurchases of less than
this amount would require no regulatory notification.  (The Federal Reserve
Board may permit repurchases in excess of this amount if it determines that the
repurchase would not constitute an unsafe or unsound practice and that it would
not violate any applicable law, rule, regulation or order, or any condition
imposed by, or written agreement with, the Federal Reserve Board.  At present,
neither Bank of the Sierra nor Sierra Bancorp has any plans to repurchase its
Common Stock.)  However, such notice and approval is not required for a bank
holding company that would be treated as "well capitalized" under applicable
regulations of the Federal Reserve Board, that has received a composite "1" or
"2" rating at its most recent bank holding company inspection by the Federal
Reserve Board, and that is not the subject of any unresolved supervisory issues.

     Finally, a bank holding company structure may provide more financing
alternatives to subsidiaries of the holding company, particularly under changing
conditions in financial markets. Traditionally, bank holding companies have had
greater access to institutional debt markets than banks and are not subject to
certain borrowing restrictions which apply to banks (except for regulatory debt-
to-equity ratio and policies and considerations of safety and soundness).  To
provide capital to one of its subsidiaries, a holding company might borrow in
reliance on its consolidated financial condition, and not just the financial
condition of the affected subsidiary, without the need to sell additional common
stock or other equity securities.  However, due to our asset size, we would be
required to meet all applicable capital requirements on a consolidated basis, so
that the holding company would not be able to borrow money to infuse capital
into Bank of the Sierra in order to increase Bank of the Sierra's capital
levels, if the resulting capital ratios on a consolidated basis were
insufficient.  (Sierra Bancorp could, however, infuse such capital for purposes
of increasing Bank of the Sierra's legal lending limit or in situations where
bank regulators might require a higher leverage capital ratio for Bank of the
Sierra than the Federal Reserve Board would require for the holding company.)
At present, neither Bank of the Sierra nor Sierra Bancorp has any present plans
to borrow funds for the use of or to contribute to any subsidiary of Sierra
Bancorp.  There can be no assurance, however, as to the method or type of
financing arrangements that will be available to Sierra Bancorp if the
reorganization is completed.

Description of the Plan of Reorganization and Agreement of Merger

     Sierra Bancorp has been organized at the direction of Bank of the Sierra
and initially will hold all the stock of Sierra Merger Corporation, a newly
organized California corporation.  The reorganization plan is proposed to be
accomplished by merging Bank of the Sierra with and into Sierra Merger
Corporation.  Upon consummation of the reorganization, Bank of the Sierra will
survive, will continue to be named Bank of the Sierra and will continue to
operate under its existing Certificate of Authority issued by the Department of
Financial Institutions.

     On the effective date of the reorganization, shareholders of Bank of the
Sierra will automatically become shareholders of Sierra Bancorp, with each share
of Bank of the Sierra Common Stock held by them being converted

                                       20


into one share of Sierra Bancorp's Common Stock. The 100 outstanding shares of
Sierra Bancorp held by James C. Holly, which are currently the only outstanding
shares of Sierra Bancorp, will be redeemed for nominal consideration of $100 and
the shares of Sierra Merger Corporation will be converted into shares of Bank of
the Sierra. The rights of the holders of Sierra Bancorp Common Stock will be
substantially the same as the rights of the holders of Bank of the Sierra Common
Stock. For a discussion of these rights, see "Comparison of Rights of
Shareholders of Sierra Bancorp and Bank of the Sierra."

     Upon consummation of the reorganization, outstanding certificates for
shares of Bank of the Sierra Common Stock will represent shares of Sierra
Bancorp Common Stock.  Shareholders will be entitled to exchange their present
certificates for new certificates evidencing shares of Sierra Bancorp Common
Stock.  Following consummation of the reorganization, Bank of the Sierra will
notify each shareholder and request that each such record holder present his or
her certificate to Sierra Bancorp for a new certificate evidencing shares of
Sierra Bancorp Common Stock.  Until so exchanged, the certificates for shares of
Bank of the Sierra Common Stock will represent the shares of Sierra Bancorp
Common Stock into which the shares of Bank of the Sierra Common Stock have been
converted.

     Consummation of the reorganization requires the affirmative vote or consent
of a majority of the issued and outstanding shares of Common Stock of Bank of
the Sierra, Sierra Bancorp and Sierra Merger Corporation, the non-disapproval by
the Federal Reserve Board of Sierra Bancorp's notice of intention to become a
bank holding company, the approval of the Department of Financial Institutions
for Sierra Bancorp to acquire control of Bank of the Sierra, the approval of the
FDIC for Bank of the Sierra to merge with Sierra Merger Corporation and the
fulfillment of certain other legal requirements.  It is anticipated that the
effective date of the reorganization will be in April, 2001 or after the receipt
of all governmental approvals required for the reorganization and the expiration
of any applicable waiting periods related thereto, whichever is later.

     If any action, suit or proceeding should be threatened or instituted with
respect to the proposed reorganization, the Board of Directors of Bank of the
Sierra reserves the right, in its sole discretion, to terminate the transaction
at any time before the effective date.  Moreover, if for any other reason the
consummation of the reorganization is inadvisable in the opinion of the Boards
of Directors of Bank of the Sierra, Sierra Merger Corporation or Sierra Bancorp,
the reorganization may be terminated by any of them either before or after the
shareholders of Bank of the Sierra vote to approve the reorganization.  If the
holders of a majority of the issued and outstanding shares of Bank of the Sierra
should fail to approve the reorganization, the conditions and legal requirements
to consummate the reorganization are not satisfied or fulfilled, or the
transaction is otherwise terminated as provided above, the business of Bank of
the Sierra would continue to operate under the ownership of its then-existing
shareholders.

Costs of Reorganization

     The costs of the reorganization to Sierra Bancorp and Bank of the Sierra
are estimated at approximately $125,000.  If the reorganization is consummated,
costs of the reorganization will be assumed and paid, to the extent properly
allocated, by Sierra Bancorp and Bank of the Sierra.  In the event the
reorganization is not consummated, such costs as have been incurred, including
the cost of organizing Sierra Bancorp will be assumed and paid by Bank of the
Sierra.

Accounting Treatment

     Because the proposed transaction is a reorganization with no change in
ownership interests, the consolidated financial statements of Sierra Bancorp and
Bank of the Sierra will retain the former bases of accounting of Bank of the
Sierra and will initially be identical to Bank of the Sierra's consolidated
financial statements prior to the reorganization.

Rights of Dissenting Shareholders

     Shareholders of Bank of the Sierra do not have dissenters' rights with
respect to the reorganization.

                                       21


Affiliate Restrictions

     The shares of Sierra Bancorp stock will be registered under the Securities
Act of 1933. However, the resale of these shares by the directors, executive
officers and principal shareholders may be restricted by the 1933 Act and by SEC
rules if the directors, principal officers, and principal shareholders are
deemed to be "affiliates" as that term is defined by the 1933 Act and SEC rules.

     Persons considered to be in control of an issuer are considered as
"affiliates."  Such persons may include officers and directors of Bank of the
Sierra or Sierra Bancorp, as well as any shareholders who own 10% or more of
Sierra Bancorp's outstanding stock. Sierra Bancorp stock held by "affiliates" of
Sierra Bancorp can be sold only if such shares are registered or transferred in
a transaction exempt from registration under the 1933 Act, for instance under
SEC Rules 144 and 145, or through a private placement. SEC Rules 144 and 145
generally require that before an affiliate can sell stock:

     .    There must be on file with the SEC public information filed by the
          issuer;

     .    The affiliate must sell his stock in a unsolicited broker's
          transaction or directly to a market maker; and

     .    During any three-month period, the amount of the securities that can
          be sold is limited to the greater of 1% of the outstanding stock of
          the issuer or the average weekly trading volume during the last four
          calendar weeks.

     It may be advisable for those shareholders who may become "affiliates" of
Sierra Bancorp to consult their legal counsel before selling any Sierra Bancorp
stock.

Federal Income Tax Consequences

     The following discussion, which is a summary of the opinion of RSM
McGladrey, Inc., which is affiliated with McGladrey & Pullen, LLP, Bank of the
Sierra's certified public accountants, is limited to all material federal income
tax consequences of the proposed reorganization and does not discuss state,
local or foreign tax consequences or all of the tax consequences that might be
relevant to shareholders of Bank of the Sierra entitled to special tax
treatment.

     In the opinion of RSM McGladrey, Inc., the proposed reorganization will
qualify for federal income tax purposes as a reorganization within the meaning
of Section 368 of the Internal Revenue Code of 1986.  This opinion is
conditioned upon the accuracy of various representations made to RSM McGladrey,
Inc. and certain assumptions made by RSM McGladrey, Inc.  The opinion is based
on current law and assumes that the reorganization is consummated as described
herein.  Neither this summary nor the opinion of RSM McGladrey, Inc. is binding
on the IRS and no ruling from the IRS has been sought or will be sought with
respect to such tax consequences.

     Based upon the qualification of the reorganization as a reorganization
within the meaning of Section 368 of the Internal Revenue Code:

     (a)  No gain or loss will be recognized by Bank of the Sierra, Sierra
Merger Corporation or Sierra Bancorp as a result of the reorganization under
361(a) and 357(a) of the Internal Revenue Code and Revenue Ruling 57-278;

     (b)  No gain or loss will be recognized by the shareholders of Bank of the
Sierra upon receipt of Sierra Bancorp Common Stock in exchange for their shares
of Bank of the Sierra Common Stock pursuant to the reorganization;

     (c)  The Sierra Bancorp Common Stock received by the shareholders of Bank
of the Sierra in exchange for their Bank of the Sierra Common Stock will have
the same basis for federal income tax purposes as the basis of the shares of

                                       23


     Authorized Capital Stock

     Bank of the Sierra currently has authorized capital consisting of
24,000,000 shares of common stock.  Of these authorized shares, as of December
31, 2000, 9,212,280 shares of Common Stock were issued and outstanding.  In
addition, there were options outstanding to purchase 1,055,000 shares of Bank of
the Sierra Common Stock pursuant to Bank of the Sierra's Stock Option Plan.
Upon the effectiveness of the reorganization, all outstanding options to
purchase Bank of the Sierra Common Stock under Bank of the Sierra's Stock Option
Plan, will be automatically converted to options to purchase Sierra Bancorp
Common Stock.  Bank of the Sierra has no other outstanding options, warrants or
other outstanding rights to purchase shares of Bank of the Sierra Common Stock.

     Sierra Bancorp currently has authorized capital consisting of 24,000,000
shares of common stock.  Of these authorized shares, 100 shares of common stock
have been issued.

     In the reorganization, Sierra Bancorp will issue approximately 9,212,280
shares of Sierra Bancorp Common Stock in exchange for all of the outstanding
shares of Bank of the Sierra Common Stock.  The balance of Sierra Bancorp's
authorized common stock will be available to be issued when and as the Board of
Directors of Sierra Bancorp determines it is advisable to do so.  While there
are no present plans or agreements to issue any additional shares of Sierra
Bancorp's common stock, such shares of common stock could be issued for the
purpose of raising additional capital, in connection with acquisitions of other
assets or investments, or for other corporate purposes.  The Board of Directors
of Sierra Bancorp will generally have the authority to issue shares of common
stock, without obtaining the approval of existing security holders.  If
additional shares of Sierra Bancorp's common stock were to be issued, the
existing holders of Sierra Bancorp Common Stock would own a proportionately
smaller portion of the total number of shares of the then issued and outstanding
common stock.

     Dividend Rights

     The shareholders of Bank of the Sierra are entitled to dividends when, as
and if declared by your Board of Directors out of funds legally available
therefor.  Since we are a state-chartered bank, our ability to pay dividends or
make distributions to our shareholders is subject to restrictions set forth in
the California Financial Code.  The California Financial Code provides that
neither a bank nor any majority-owned subsidiary of a bank may make a
distribution to its shareholders in an amount which exceeds the lesser of (i)
the bank's retained earnings or (ii) the bank's net income for its last three
fiscal years, less the amount of any distributions made by the bank or by any
majority-owned subsidiary of the bank during such period.  Notwithstanding the
foregoing, a bank may, with the prior approval of the California Commissioner of
Financial Institutions, make a distribution to the shareholders of the bank in
an amount not exceeding the greatest of: (i) its retained earnings; (ii) its net
income for its last fiscal year; or (iii) the net income of the bank for its
current fiscal year.  If the Commissioner of Financial Institutions finds that
the shareholders' equity of the bank is inadequate or that the making of a
distribution by a bank would be unsafe or unsound, the Commissioner of Financial
Institutions may order the bank to refrain from making a proposed distribution.
The payment of any cash dividends by Bank of the Sierra also depends on its
meeting applicable regulatory capital requirements.

     The holders of Sierra Bancorp Common Stock will be entitled to receive
dividends when and as declared by its Board of Directors out of funds legally
available therefor, subject to the restrictions set forth in the California
Corporations Code.  The Corporations Code provides that a corporation may make a
distribution to its shareholders if the corporation's retained earnings equal at
least the amount of the proposed distribution.  The Corporations Code further
provides that, in the event that sufficient retained earnings are not available
for the proposed distribution, a corporation may nevertheless make a
distribution to its shareholders if it meets two conditions, which generally are
as follows:  (i) the corporation's assets equal at least 1 1/4 times its
liabilities; and (ii) the corporation's current assets equal at least its
current liabilities or, if the average of the corporation's earnings before
taxes on income and before interest expense for two preceding fiscal years was
less than the average of the corporation's interest expense for such fiscal
years, then the corporation's current assets must equal at least 1 1/4 times its
current liabilities.

                                       24


     The payment of dividends by Sierra Bancorp will depend on Sierra Bancorp's
net income, financial condition, regulatory requirements and other factors,
including the results of Bank of the Sierra's operations.  Following the
reorganization, Sierra Bancorp anticipates paying dividends in the future
consistent with Bank of the Sierra's recently revised dividend policy.  (See
"DIVIDENDS.")  However, no assurance can be given that Bank of the Sierra's and
Sierra Bancorp's future earnings in any given year will justify the payment of
such a dividend.  (See "RISK FACTORS B There is no  Assurance Sierra Bancorp
Will be Able to Pay Dividends.")

     Voting Rights

     All voting rights with respect to Bank of the Sierra currently are vested
in the holders of Bank of the Sierra Common Stock.  All voting rights with
respect to Sierra Bancorp will be vested in the holders of Sierra Bancorp Common
Stock.

     Holders of Bank of the Sierra Common Stock are entitled to and holders of
Sierra Bancorp Common Stock will be entitled to one vote for each share of
Common Stock standing in his or her name on the books of Bank of the Sierra or
Sierra Bancorp, as applicable, on any matter submitted to the vote of the
shareholders.  Shareholders do not have cumulative voting rights in connection
with the election of directors.  Bank of the Sierra's Board of Directors is
divided into two (2) classes of directors (one class currently consisting of
five and the other of four directors), serving terms which will expire in 2002
and 2003 (see "PROPOSAL 1 B ELECTION OF DIRECTORS").  The Board of Directors of
Sierra Bancorp will also be divided into two (2) such classes and the directors
will also be elected for terms of two years.

     Preemptive Rights

     Holders of Bank of the Sierra Common Stock do not have and holders of
Sierra Bancorp Common Stock will not have preemptive rights.

     Liquidation Rights

     The holders of Bank of the Sierra Common Stock are entitled, and the
holders of Sierra Bancorp Common Stock will also be entitled, to receive their
pro rata share of the assets of Bank of the Sierra or Sierra Bancorp
distributable to shareholders upon liquidation, subject, however, to the
preferential rights, if any, of the holders of outstanding senior securities.

     Charter Documents

     The Bylaws and Articles of Incorporation of Bank of the Sierra and Sierra
Bancorp are similar in all material respects, except that the stated purpose of
Bank of the Sierra in its Articles of Incorporation is to engage in the banking
business and the stated purpose of Sierra Bancorp is to engage in any lawful
activity other than the banking business, the trust company business or the
practice of a profession.  Procedures for amending such charter documents are
discussed immediately below under "Shareholder Vote for Mergers and Other
Matters."

     Shareholder Vote for Mergers and Other Matters

     The reorganization will change the procedures required for obtaining
shareholder approval of certain matters.  Currently, approval of Bank of the
Sierra's shareholders is required, for example, for any amendment to Bank of the
Sierra's Bylaws which would change the authorized range of directors, and for
any amendments to Bank of the Sierra's Articles of Incorporation.  Following the
reorganization, approval of Sierra Bancorp's shareholders will be required for
any amendments of this nature involving Sierra Bancorp's Articles or Bylaws, but
the Articles or Bylaws of Bank of the Sierra could be amended by action of
Sierra Bancorp's Board of Directors, authorizing Sierra Bancorp, as sole
shareholder of Bank of the Sierra, to approve such amendments.

     With respect to mergers, reorganizations and acquisitions involving banks,
the California Financial Code provides that any "reorganization," as that term
is defined in the Corporations Code, is subject to the shareholder

                                       25


approval requirements of the Corporations Code. (The term includes merger
reorganizations, exchange reorganizations and sale-of-assets reorganizations.)
As the Corporations Code will also apply to Sierra Bancorp, the rights of Sierra
Bancorp's shareholders will be essentially the same as the current rights of
Bank of the Sierra's existing shareholders with respect to such reorganizations.
In this connection, the Corporations Code generally requires a vote by the
shareholders of (i) each "constituent corporation" to a merger; (ii) a
corporation selling all or substantially all of its assets; (iii) the acquiring
corporation in either a share-for-share exchange or a sale-of-assets
reorganization, and (iv) a parent corporation (even though it is not a
"constituent corporation") whose equity securities are being issued in
connection with a corporate reorganization such as a triangular merger. The
Corporations Code does not require shareholder approval in the case of any
corporation in a merger as to which such corporation and/or its shareholders
will have five-sixths or more of the voting power of the surviving or acquiring
corporation after consummation of the merger (unless the shares acquired in such
a merger have different rights, preferences, privileges or restrictions than
those surrendered). With certain exceptions, the Corporations Code also requires
a class vote when a shareholder vote is required in connection with these
transactions.

     Dissenters' Rights

     The Corporations Code provides that holders of Sierra Bancorp Common Stock
would be entitled, subject to the provisions of Chapter 13, to dissenters'
rights in connection with any transaction which constitutes a reorganization (as
defined in the Corporations Code).  Under the Corporations Code, in connection
with the merger of a corporation for which the approval of outstanding shares is
required, dissenting shareholders of such corporation who follow prescribed
statutory procedures are entitled to receive payment of the fair market value of
their shares.  No such rights are available, however, if the shares are listed
on a national securities exchange certified by the California Commissioner of
Corporations or appear on the Federal Reserve list of over-the-counter margin
stocks unless (i) such shares are subject to certain restrictions on transfer or
(ii) the holders of at least 5% of such shares elect dissenters' rights.
However, pursuant to the California Financial Code, shareholders of Bank of the
Sierra Common Stock are not entitled to dissenters' rights in connection with
any transactions between two banking institutions which constitutes a
reorganization (as defined in the Corporations Code) where Bank of the Sierra is
the corporation surviving such transaction, even if dissenters' rights were
otherwise available pursuant to Chapter 13.

Board of Directors' Recommendation and Required Vote

     Approval of the plan of reorganization and agreement of merger requires the
approval of owners of at least a majority of the outstanding shares of the
common stock of Bank of the Sierra. Bank of the Sierra's directors and executive
officers who beneficially owned in the aggregate approximately 4,226,573 voting
shares or 45.9% of the outstanding shares of Bank of the Sierra common stock as
of March 26, 2001, intend to vote in favor of the reorganization.

  Your Board of Directors unanimously recommends a vote "for" this proposal.

                                 DIVIDENDS

Sierra Bancorp

     Since the date of its incorporation, Sierra Bancorp has paid no dividends.
After completion of the reorganization, the amount and timing of future
dividends will be determined by its Board of Directors and will substantially
depend upon the earnings and financial condition of its principal subsidiary,
Bank of the Sierra. The ability of Sierra Bancorp to obtain funds for the
payment of dividends and for other cash requirements is largely dependent on the
amount of dividends which may be declared by its subsidiary, Bank of the Sierra.

     The power of Bank of the Sierra's Board of Directors to declare cash
dividends is limited by statutory and regulatory restrictions which restrict the
amount available for cash dividends depending upon the earnings, financial
condition and cash needs of Bank of the Sierra, as well as general business
conditions.  Since we are a state-chartered bank, our ability to pay dividends
or make distributions to its shareholders is subject to restrictions set forth
in the California Financial Code.  (See "BANK HOLDING COMPANY REORGANIZATION B
Comparison of Rights of Shareholders of Sierra Bancorp and Bank of the Sierra B
Dividend Rights.")

Bank of the Sierra

     Bank of the Sierra paid cash dividends of $2.12 million or $0.23 per share
during 2000 and $2.02 million or $0.22 per share in 1999, representing
approximately thirty-eight percent (38%) and thirty-nine percent (39%) of the
prior year's earnings, respectively, pursuant to a policy of paying quarterly
cash dividends totaling at least thirty-five percent (35%) of the prior year's
net earnings to the extent consistent with general considerations of safety and
soundness and provided that such payments do not adversely affect Bank of the
Sierra=s financial condition.  In view of the recent growth of Bank of the
Sierra resulting in part from its acquisition of Sierra National Bank in May,
2000, the Board of Directors has decided to revise the dividend policy for 2001
and the foreseeable future to pay cash

                                       27


dividends totaling approximately between twenty percent (20%) and twenty-five
percent (25%) of the prior year's net earnings, subject to the same limitations
as the previous dividend policy. While Bank of the Sierra anticipates paying
cash dividends in the future pursuant to this new policy, no assurance can be
given that Bank of the Sierra's future earnings in any given year will justify
the payment of such a dividend. The Bank has also implemented a plan to return
the Bank from its "adequately capitalized" position to a "well capitalized"
position by the end of 2001 if possible, and if necessary the Bank may consider
a further modification of its dividend policy to achieve this goal.

     Sierra Bancorp anticipates paying dividends in the future consistent with
Bank of the Sierra's dividend policy as described above.  However, no assurance
can be given that Bank of the Sierra's and Sierra Bancorp's future earnings in
any given year will justify the payment of such a dividend.  For a discussion of
certain legal restrictions on Sierra Bancorp's ability to pay cash dividends,
see "BANK HOLDING COMPANY REORGANIZATION B Comparison of Rights of Shareholders
of Sierra Bancorp and Bank of the Sierra B Dividend Rights" above.

                    HISTORY AND BUSINESS OF SIERRA BANCORP

Organization

     Sierra Bancorp was incorporated under the laws of California on November
16, 2000 at the direction of Bank of the Sierra for the purpose of becoming a
bank holding company by acquiring all of the outstanding capital stock of  Bank
of the Sierra.  In order to effect the reorganization, 100 shares of Sierra
Bancorp Common Stock have been issued to James C. Holly for an aggregate
consideration of $100.  Upon consummation of the reorganization, these 100
shares will be redeemed by Sierra Bancorp for $100.

     Sierra Bancorp has purchased for $100, and owns 100% of the capital stock
of Sierra Merger Corporation, a Delaware corporation, organized for the sole
purpose of facilitating the reorganization.

Business

     Sierra Bancorp has not yet engaged in any business activity.  Sierra
Bancorp has filed with the Federal Reserve Board its notice of intention to
become a bank holding company through the acquisition of 100% of the voting
shares of Bank of the Sierra pursuant to the Bank Holding Company Act.  Sierra
Bancorp has also filed an application with the Department of Financial
Institutions for approval to acquire control of Bank of the Sierra pursuant to
the provisions of the California Financial Code, and Bank of the Sierra and
Sierra Merger Corporation have filed an application with the FDIC, providing for
the merger of Sierra Merger Corporation with and into Bank of the Sierra.  Upon
consummation of the reorganization, Sierra Bancorp will own all of the Common
Stock of Bank of the Sierra, Bank of the Sierra will be Sierra Bancorp's wholly-
owned bank subsidiary and Sierra Bancorp will be registered as a bank holding
company.  As of the date of this document, the Federal Reserve Board, the
Department of Financial Institutions and the FDIC have all issued the approvals
or notices of non-disapproval needed to consummate the reorganization subject to
certain conditions.  While we do not know of any reason that we would not be
able to comply with such conditions, we cannot be certain that we will be able
to meet them.

     Upon consummation of the reorganization, Sierra Bancorp will have no
significant assets other than the shares of Bank of the Sierra's Common Stock
acquired in the reorganization, and will have no significant liabilities.
Initially, Sierra Bancorp will neither own nor lease any property, but will
instead use the premises, equipment and furniture of Bank of the Sierra.

     At the present time, Sierra Bancorp has no specific plans to engage in any
activities other than acting as a bank holding company for Bank of the Sierra.
However, subject to the constraints under the Bank Holding Company Act, Sierra
Bancorp may acquire other financial institutions in the future.  In addition, in
the future Sierra Bancorp may seek to raise additional equity capital through
the sale of its securities or the securities of its subsidiaries, although it
has no current plans to do so.

Management

     The current executive officers of Sierra Bancorp are James C. Holly,
President and Chief Executive Officer; Kenneth E. Goodwin, Executive Vice
President and Chief Operating Officer; Jack B. Buchold, Senior Vice President
and Chief Financial Officer; and Charlie C. Glenn, Senior Vice President and
Chief Credit Officer.  Such individuals also serve and will continue to serve in
those same capacities for Bank of the Sierra following the reorganization, and
Bank of the Sierra initially will be solely responsible for their direct
compensation.

     It is anticipated that in the future, if Sierra Bancorp becomes involved in
additional businesses, Sierra Bancorp may add additional officers and employees
and that Bank of the Sierra and other subsidiaries of Sierra Bancorp, if any,
will pay cash dividends and management fees to support the expenses of Sierra
Bancorp.  There are presently no specific plans, arrangements or commitments
with respect to such matters.

                                       30


     All of Sierra Bancorp's directors are also directors of Bank of the Sierra.
They were appointed to Sierra Bancorp's Board of Directors by the sole
incorporator on December 14, 2000.  For further information regarding these
directors, see "PROPOSAL 1-ELECTION OF DIRECTORS-Information Concerning
Directors, Nominees and Executive Officers" above.  It is anticipated that
directors of Sierra Bancorp initially will not receive fees for their attendance
at Board meetings and for attendance at committee meetings when such committees
are established.  However, these persons will continue to receive directors'
fees for serving on the Board of Directors and committees of Bank of the Sierra.

Indemnification

     Section 317 of the California Corporations Code governs indemnification of
the directors and officers of both Sierra Bancorp and Bank of the Sierra.  Under
this section, officers and directors may be indemnified against expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
in connection with proceedings other than derivative suits, in which such
persons were parties or threatened to be made parties.  In order for the
corporation to make indemnification, there must be a determination by (a) a
majority vote of a quorum of the Board of Directors, consisting of directors who
are not parties to such proceeding, (b) approval of the shareholders pursuant to
Section 153 of the California Corporations Code, with the shares owned by the
person to be indemnified not being entitled to vote thereon, or an order of the
court in which such proceeding is or was pending that the officer or director
acted in good faith in a manner such person reasonably believed to be in the
best interests of the corporation, and in the case of a criminal proceeding,
such person had no reasonable cause to believe the conduct of such person was
unlawful.  This section further provides that indemnification may be paid in
connection with derivative suits, in the same manner as described above, except
that (a) with respect to derivative suits, the authority authorizing the
indemnification must find that such person acted in good faith, in a manner such
person believed to be in the best interests of the corporation and with such
care, including reasonable inquiry, as an ordinarily prudent person in a like
position would use under the circumstances, and (b) court approval is required
for indemnification of expenses or amounts incurred in respect of any claim or
matter in which a director or officer has been adjudged to be liable to the
corporation in the performance of such person's duty to the corporation; in
settling or otherwise disposing of a threatened or pending action, with or
without action which is settled or otherwise disposed of without court approval.

     Sierra Bancorp's Articles of Incorporation and Bylaws provide, among other
things, for the indemnification of Sierra Bancorp's directors, officers and
agents, and authorize the Board to pay expenses incurred by, or to satisfy a
judgment or fine rendered or levied against, such agents in connection with any
personal legal liability incurred by that individual while acting for the
corporation within the scope of his or her employment.  Such provisions of
Sierra Bancorp's Articles of Incorporation and Bylaws are subject to certain
limitations imposed under state and federal law.  It is the policy of the Board
of Directors that Sierra Bancorp's executive officers and directors shall be
indemnified to the maximum extent permitted under applicable law and Sierra
Bancorp's Articles of Incorporation and Bylaws.  These provisions are
essentially identical to the comparable provisions in Bank of the Sierra's
Articles of Incorporation and Bylaws, and Bank of the Sierra's policy regarding
indemnification of executive officers and directors is also the same as that of
Sierra Bancorp.  Bank of the Sierra has obtained liability insurance covering
all of Bank of the Sierra's officers and directors and Sierra Bancorp expects to
have similar insurance in force before the reorganization is effective.

     The corporation's Articles of Incorporation also currently provide for the
limitation or elimination of personal liability of the corporation's directors
to the corporation or its shareholders for monetary damages, to the extent
permitted by California law.  However, under federal law, the FDIC may seek
monetary damages from bank or holding company directors in cases involving gross
negligence or any greater disregard of the duty of care, notwithstanding any
provisions of state law which may permit limitations on director liability in
such circumstances.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling Sierra
Bancorp under the provisions in Sierra Bancorp's Articles of Incorporation and
Bylaws, Sierra Bancorp has been informed that, in the opinion of the SEC, this
kind of indemnification is against public policy as expressed in the securities
Act of 1933, and is therefore unenforceable.

                                       31


                  HISTORY AND BUSINESS OF BANK OF THE SIERRA

General

     Bank of the Sierra was incorporated under the laws of the State of
California on September 14, 1977, and commenced operations as a California
state-chartered bank on January 19, 1978.  We operate nine full-service branch
offices in seven Tulare County communities, five full-service branch offices in
Kern County; and one full-service branch office each in Kings County and Fresno
County; and offer a full range of banking services to individuals and various
sized businesses in the communities which we serve.  The locations of those
offices are:

     In addition, our Bank Card Center is located at 80 North Main Street,
Porterville, California.  We also have specialized credit centers for
agricultural lending and construction and real estate lending within a number of
these branch offices.  These facilities are located in the cities of Porterville
and Visalia in Tulare County, the city of Fresno in Fresno County, the city of
Bakersfield in Kern County, and the city of Hanford in Kings County.

     Prior to 1997, Bank of the Sierra had grown exclusively by establishing de
novo full-service branch offices and credit centers in each of its current
locations.  In February 1997, we made our first branch purchase of the Dinuba
Office of Wells Fargo Bank.  Between February 1997 and September, 1999 we opened
three additional de novo offices, in Tulare, Hanford, and Fresno.  In May 2000,
we added four new branches by the acquisition of Sierra National Bank.  These
branches stretch from California City, in the high desert, westerly to
Bakersfield along the Highway 58 corridor, a distance of approximately 81 miles.

     With a predominant focus on personal service, Bank of the Sierra has
positioned itself as a multi-community independent bank serving the financial
needs of individuals and businesses, including agricultural and real estate
customers in Tulare and other surrounding counties.  We are currently the
largest independent bank headquartered in Tulare County.  Although we are
primarily a retail oriented independent community bank, we have three other
dimensions which surround this core of community banking: agricultural lending,
credit card loans and real estate financing (both construction and long term).

                                       32


     The Agricultural Credit Centers, located in Fresno, Porterville, and
Bakersfield, provide a complete line of credit services supporting the
agricultural activities which are key to the continued economic development of
the communities we serve.  "Ag lending" clients include a full range of
individual farming customers, small business farming organizations and major
corporate farming units.

     The Bank Card Center, headquartered in Porterville, provides a range of
credit, debit and ATM card services, which are made available to each of the
customers served by the branch banking offices.  That center also provides
credit card services to a limited number of affinity program participants.

     The Real Estate Center, with offices in Fresno, Hanford, Visalia,
Porterville, and Bakersfield, is responsible for a complete line of land
acquisition and development loans, construction loans for residential and
commercial development, and the origination of 1-4 family first mortgage loans
and multifamily credit facilities.  In addition, secondary market services are
provided though this group and its affiliations with Freddie Mac, Fannie Mae and
various non-governmental programs.

     We also have an orientation towards Small Business Administration lending
and achieved the designation of Preferred Lender during 1999.  At the current
time, one branch manager is responsible for the program, which generated
approximately $11.1 million in loans during the past year.  It is anticipated
that loans under this program will become an increasing segment of our loan
portfolio over the next few years.

     Our principal lending services include commercial, real estate, home
equity, agricultural and consumer loans. Related services include credit cards,
installment note collection, cashier's checks, traveler's checks, bank-by-mail,
ATM, night depository, safe deposit boxes, direct deposit, automated payroll
services and other customary banking services.  As of December 31, 2000, the
principal areas in which we directed our lending activities, and the percentage
of our total loan portfolio for which each of these areas was responsible, were
as follows: (i) agricultural loans (3.87%); (ii) commercial and industrial
(including SBA) loans (16.70%); (iii) real estate loans (68.31%); (iv) consumer
loans (8.40%); and (v) credit cards (2.72%).

     In addition to the lending activities noted above, we offer a wide range of
deposit products for the retail banking market including checking, interest
bearing transaction, savings, time certificates of deposit and retirement
accounts, as well as telephone banking and internet banking with bill pay
options.  As of December 31, 2000, we had 47,262 deposit accounts with balances
totaling approximately $527.8 million, compared to 32,726 deposit accounts with
balances totaling approximately $385.8 million at December 31, 1999.

     Bank of the Sierra attracts deposits through its customer oriented product
mix, competitive pricing, convenient locations, extended hours and drive-up
banking, all provided with the highest level of customer service.  We also offer
other products and services to our customers, which complement the lending and
deposit services previously reviewed.  These include shared ATM and Point of
Sale (POS) networks through which customers can gain access to the national and
international funds transfer networks.  During 1997, in our continuing efforts
to meet the needs of our various communities, we added a Spanish language option
to our network of ATMs throughout our service area.  During the past two years,
we have substantially enhanced our ATM locations to include off-site areas not
previously served by cash or deposit facilities, and we now have a total of
seven such remote centers.  These units are located in a hospital, county
offices, a college campus, a motel and a Fair office. These locations facilitate
cash advances and deposits which would not otherwise be available to consumers
at non-branch locations, thereby increasing consumer convenience.  In addition,
we have a mobile ATM unit which is transportable and is used at fairs,
exhibitions, and various other community functions within our market area. In
addition to such specifically oriented customer applications, we provide safe
deposit, wire transfer capabilities and a convenient customer service group to
answer questions and assure a high level of customer satisfaction with the level
of services and products we provide.

     Most of the Bank's deposits are attracted from individuals, business-
related sources and smaller municipal entities.  This results in a relatively
modest average deposit balance of approximately $11,000 at December 31, 2000,
but makes the Bank less subject to adverse effects from the loss of a
substantial depositor who may be seeking higher

                                       33


yields in other markets or who may have need of money otherwise on deposit with
the Bank, especially during periods of inflation or conservative monetary
policies.

     For non-deposit services, we also formed a strategic alliance with
Investment Centers of America, Inc. of Bismarck, North Dakota.  Through this
arrangement, registered and licensed representatives of this company provide our
customers in our Porterville, Visalia and Tulare offices with convenient access
to annuities, insurance products, mutual funds, and a full range of investment
products, with available services by appointment in our other branches.

     We do not believe there is a significant demand for additional trust
services in our service areas, and we do not operate or have any present
intention to seek authority to operate a Trust Department.  We believe that the
cost of establishing and operating such a department would not be justified by
the potential income to be gained therefrom.  However, we occasionally make
arrangements with correspondent institutions to offer trust services to our
customers upon request.

     We currently have one wholly-owned subsidiary, Sierra Phoenix, Inc., whose
sole function is to hold certain investments which we are not permitted to hold
directly.  This subsidiary currently holds two investments, one of which is
stock in Phoenix International, Ltd., Inc., a computer software company which
specializes in the production and marketing of client user software for
financial institutions. The other investment held is an equity position in
California Banker's Insurance Agency, an entity which was formed to facilitate
insurance product sales after enabling legislation under the Gramm-Leach-Bliley
Financial Services Modernization Act was passed.  Bank of the Sierra is
currently a passive investor, through Sierra Phoenix, Inc., in both Phoenix
International, Inc. and California Banker's Insurance Agency.

Competition

     The banking business in California generally, and specifically in our
market areas, is highly competitive with respect to virtually all products and
services and has become increasingly so in recent years. The industry continues
to consolidate and strong, unregulated competitors have entered banking markets
with focused products targeted at highly profitable customer segments. Many
largely unregulated competitors are able to compete across geographic boundaries
and provide customers increasing access to meaningful alternatives to banking
services in nearly all significant products.  These competitive trends are
likely to continue.

     With respect to commercial bank competitors, the business is largely
dominated by a relatively small number of major banks with many offices
operating over a wide geographical area, which banks have, among other
advantages, the ability to finance wide-ranging and effective advertising
campaigns and to allocate their investment resources to regions of highest yield
and demand.  Many of the major banks operating in the area offer certain
services which we do not offer directly (but some of which we offer through
correspondent institutions).  By virtue of their greater total capitalization,
such banks also have substantially higher lending limits than we do.

     In addition to other banks, competitors include savings institutions,
credit unions, and numerous non-banking institutions, such as: finance
companies, leasing companies, insurance companies, brokerage firms, and
investment banking firms.  In recent years, increased competition has also
developed from specialized finance and non-finance companies that offer
wholesale finance, credit card, and other consumer finance services, including
on-line banking services and personal finance software.  Strong competition for
deposit and loan products affects the rates of those products as well as the
terms on which they are offered to customers.  Mergers between financial
institutions have placed additional pressure on banks within the industry to
streamline their operations, reduce expenses, and increase revenues to remain
competitive. Competition has also intensified due to recently enacted federal
and state interstate banking laws, which permit banking organizations to expand
geographically, and the California market has been particularly attractive to
out-of-state institutions.  The recently enacted Financial Modernization Act,
which, effective March 11, 2000, has made it possible for full affiliations to
occur between banks and securities firms, insurance companies, and other
financial companies, is also expected to intensify competitive conditions (see
"SUPERVISION AND REGULATION-Government Policies and Legislation").

                                       34


     Technological innovation has also resulted in increased competition in
financial services markets.  Such innovation has, for example, made it possible
for non-depository institutions to offer customers automated transfer payment
services that previously have been considered traditional banking products.  In
addition, many customers now expect a choice of several delivery systems and
channels, including telephone, mail, home computer, ATMs, self-service branches,
and/or in-store branches. In addition to other banks, the sources of competition
for such products include savings associations, credit unions, brokerage firms,
money market and other mutual funds, asset management groups, finance and
insurance companies, internet only financial intermediaries, and mortgage
banking firms.

     In order to compete effectively, we rely upon local promotional activity,
personal contacts by our officers, directors, employees, and shareholders,
automated 24-hour banking, and the individualized service which we can provide
through our flexible policies.  We provide our own style of community-oriented,
personalized service oriented towards the citizens of the San Joaquin Valley,
whom we believe appreciate a more consumer-oriented environment in which to
conduct their financial transactions.  More recently we have embraced the
electronic age and installed telephone banking and internet banking with bill
payment capabilities, to meet the needs of customers with electronic access
requirements.  In addition, for customers whose loan demands exceed our legal
lending limit, we attempt to arrange for such loans on a participation basis
with correspondent banks.  We also assist our customers requiring other services
we do not offer in obtaining such services from our correspondent banks.

     Our credit card business is subject to an even higher level of competitive
pressure than our general banking business.  There are a number of major banks
and credit card issuers that are able to finance often highly successful
advertising campaigns with which smaller community banks generally do not have
the resources to compete.  As a result, our credit card outstandings are much
more likely to increase at a slower rate than that which might be seen in
nationwide issuers' year-end statistics.  In addition, many non-financial
institutions, such as providers of various retail products, offer many types of
credit cards providing competition for us.

Employees

     As of December 31, 2000, Bank of the Sierra had 282 full-time and 41 part-
time employees.  On a full time equivalent basis, our staff level was 323 at
December 31, 2000.

     None of our employees is concurrently represented by a union or covered by
a collective bargaining agreement. Management of Bank of the Sierra believes
that its employee relations are satisfactory.

Properties

     Bank of the Sierra operates nine full-service branch offices in seven
Tulare County communities, five full-service branch offices in Kern County and
one full-service branch office each in Kings County and Fresno County (see " --
General" above); and offers a full range of banking services to individuals and
various sized businesses in the communities which it serves.  Bank of the Sierra
owns the land and building unencumbered for a total of 13 of its branch offices
located in Porterville, Lindsay, Exeter, Three Rivers, Dinuba, Tulare, Hanford,
Fresno, Tehachapi, California City and Bakersfield.  Our other facilities,
including our Administrative Headquarters, two branch offices in Visalia and one
branch in Bakersfield, are leased.

Legal Proceedings

     From time to time, we are a party to claims and legal proceedings arising
in the ordinary course of our business.  After taking into consideration
information furnished by our counsel as to the current status of these claims or
proceedings to which we are a party, management is of the opinion that the
ultimate aggregate liability represented thereby, if any, will not have a
material adverse affect on our financial condition.

                          SUPERVISION AND REGULATION


   Both federal and state law extensively regulate bank holding companies. This
regulation is intended primarily for the protection of depositors and the
deposit insurance fund and not for the benefit of shareholders of Sierra
Bancorp. The following is a summary of particular statutes and regulations
affecting Sierra Bancorp and Bank of the Sierra. This summary is qualified in
its entirety by the statutes and regulations.

Regulation of Sierra Bancorp

     Sierra Bancorp will be a registered bank holding company under the Bank
Holding Company Act of 1956 as amended, and will be regulated by the Federal
Reserve Board. Sierra Bancorp will be required to file periodic reports with the
Federal Reserve Board and such additional information as the Federal Reserve
Board may require pursuant to the Bank Holding Company Act. The Federal Reserve
Board may conduct examinations of Sierra Bancorp and its subsidiaries, which
will include Bank of the Sierra.

     The Bank Holding Company Act requires every bank holding company to obtain
the prior approval of the Federal Reserve Board before acquiring substantially
all the assets of any bank or bank holding company or ownership or control of
any voting shares of any bank or bank holding company, if, after the
acquisition, it would own or control, directly or indirectly, more than 5% of
the voting shares of the bank or bank holding company.

     Sierra Bancorp will be prohibited by the Bank Holding Company Act, except
in statutorily prescribed instances, from acquiring direct or indirect ownership
or control of more than 5% of the outstanding voting shares of any company that
is not a bank or bank holding company and from engaging directly or indirectly
in activities other than those of banking, managing or controlling banks or
furnishing services to its subsidiaries. However, Sierra Bancorp, subject to the
prior approval of the Federal Reserve Board, may engage in any, or acquire
shares of companies engaged in, activities that are deemed by the Federal
Reserve Board to be "so closely related to banking" or managing or controlling
banks as to be a "proper incident thereto."

     In approving acquisitions by bank holding companies of companies engaged in
banking-related activities, the Federal Reserve Board considers whether the
performance of any activity by a subsidiary of the holding company reasonably
can be expected to produce benefits to the public, including greater
convenience, increased competition, or gains in efficiency, which outweigh
possible adverse effects, including over-concentration of resources, decrease of
competition, conflicts of interest, or unsound banking practices.

     Although management of Sierra Bancorp has no present intention to do so, at
some point in the future Sierra Bancorp may file an election with the Federal
Reserve Board to become a "financial holding company."  Unlike a bank holding
company, a financial holding company may engage in a broad range of activities
that are deemed by the Federal Reserve Board as "financial in nature or
incidental" to financial activities. Moreover, even in the case where an
activity cannot meet that test, the Federal Reserve Board may approve the
activity if the proposed activity is "complementary" to financial activities and
does not pose a risk to the safety and soundness of depository institutions.
One example of such activities which would be allowed for a financial holding
company but not for a bank or a simple bank holding company is real estate
development activities.

     The Federal Reserve Board has adopted capital adequacy guidelines for bank
holding companies on a consolidated basis substantially similar to those of the
FDIC currently applicable to Bank of the Sierra.  Regulations and policies of
the Federal Reserve Board also require a bank holding company to serve as a
source of financial and managerial strength to its subsidiary banks. It is the
Federal Reserve Board's policy that a bank holding company should stand ready to
use available resources to provide adequate capital funds to a subsidiary bank
during periods of financial stress or adversity and should maintain the
financial flexibility and capital-raising capacity to obtain additional
resources for assisting a subsidiary bank. Under certain conditions, the Federal
Reserve Board may conclude that certain actions of a bank holding company, such
as a payment of a cash dividend, would constitute an unsafe and unsound banking
practice.

                                       36


     Sierra Bancorp will be required to give the Federal Reserve Board prior
written notice of any repurchase of its outstanding equity securities which (for
a period of 12 months) is equal to 10% or more of Sierra Bancorp's consolidated
net worth, unless certain conditions are met.  (See discussion under "Reasons
for the Reorganization" above.)

     Bank holding company transactions with subsidiaries and other affiliates
are restricted, including qualitative and quantitative restrictions on
extensions of credit and similar transactions.

     The securities of Sierra Bancorp will also be subject to the requirements
of the Securities Act of 1933 and matters related thereto will be regulated by
the SEC. Additionally, Sierra Bancorp's securities will be registered with the
SEC under the Securities Exchange Act of 1934, just as Bank of the Sierra's
securities are now registered with the FDIC under that act. As such, Sierra
Bancorp will be subject to the same information, proxy solicitation, insider
trading, and other requirements and restrictions under federal securities law as
Bank of the Sierra has been prior to the reorganization.

Regulation of Bank of the Sierra

     As a California state-chartered bank whose accounts are insured by the FDIC
up to a maximum of $100,000 per depositor, we are subject to regulation,
supervision and regular examination by the Department of Financial Institutions
and the FDIC.  In addition, while we are not a member of the Federal Reserve
System, we are subject to certain regulations of the Federal Reserve Board.  The
regulations of these agencies govern most aspects of our business, including the
making of periodic reports, and activities relating to dividends, investments,
loans, borrowings, capital requirements, certain check-clearing activities,
branching, mergers and acquisitions, reserves against deposits and numerous
other areas.  All of such supervision and regulation of Bank of the Sierra will
continue following the reorganization and, in addition, Sierra Bancorp will be
subject to extensive supervision and regulation by the Federal Reserve Board and
the SEC (see "Regulation of Sierra Bancorp" above).

Government Policies and Legislation

     The policies of regulatory authorities, including the Federal Reserve
Board, the FDIC and the Depository Institutions Deregulation Committee, have had
a significant effect on the operating results of commercial banks in the past
and are expected to do so in the future. An important function of the Federal
Reserve System is to regulate aggregate national credit and money supply through
the means of open market dealings in securities, establishment of the discount
rate on member bank borrowings, and changes in reserve requirements against
member bank deposits. Policies of these agencies may be influenced by many
factors, including inflation, unemployment, short-term and long-term changes in
the international trade balance and fiscal policies of the United States
government.

     Effective March, 2000, the Gramm-Leach Bliley Act eliminated many of the
barriers that previously separated the insurance, securities, and banking
industries since the Great Depression. As a result, these three industries may
more freely compete with each other. The extent to which the changes made by the
Gramm-Leach Bliley Act to the structure and operation of the financial
marketplace are unknown and it is unclear how Sierra Bancorp or Bank of the
Sierra will be affected.  Sierra Bancorp may become a "financial holding
company" in the future to be able to take advantage if appropriate of the
increased flexibility provided by the Gramm-Leach Bliley Act, but it has no
current intention to do so.

     Additionally, other legislation which could affect Sierra Bancorp or Bank
of the Sierra and the financial services industry in general may be proposed in
the future. Such proposals, if enacted, may further alter the structure,
regulation, and the competitive relationship among financial institutions and
financial intermediaries, and may subject Sierra Bancorp or Bank of the Sierra
to increased regulation, disclosure and reporting requirements.  Moreover, the
various banking regulatory agencies may propose rules and regulations to
implement and enforce current and future legislation. It cannot be predicted
whether, or in what form, any such legislation or regulations will be enacted or
the extent to which Sierra Bancorp or Bank of the Sierra would be affected.

at shareholder meetings.  Any such proposal concerning the Bank's 2002 annual
meeting of shareholders must be submitted by a shareholder prior to December 29,
2001 in order to qualify for inclusion in the proxy statement relating to such
meeting.  The submission by a shareholder of a proposal does not guarantee that

     The persons named as proxies for the 2002 annual meeting of shareholders
will have discretionary authority to vote on any shareholder proposal which is
not included in the Bank's proxy materials for the meeting, unless the Bank

     We are not aware of any matters to be presented at the annual meeting other
than those matters described in this proxy statement/prospectus.  However, if
other matters properly come before the annual meeting, it is the intention of
the proxy holders designated in the attached proxy to vote said proxy in
accordance with the recommendations of your Board of Directors and authority to

                    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers

     The Articles of Incorporation and Bylaws of Sierra Bancorp provide for
indemnification of agents including directors, officers and employees to the
maximum extent allowed by California law including the use of an indemnity
agreement. Sierra Bancorp's Articles further provide for the elimination of
director liability for monetary damages to the maximum extent allowed by
California law. The indemnification law of the State of California generally
allows indemnification in matters not involving the right of the corporation, to
an agent of the corporation if such person acted in good faith and in a manner
such person reasonably believed to be in the best interests of the corporation,
and in the case of a criminal matter, had no reasonable cause to believe the
conduct of such person was unlawful. California law, with respect to matters
involving the right of a corporation, allows indemnification of an agent of the
corporation, if such person acted in good faith, in a manner such person
believed to be in the best interests of the corporation and its shareholders;
provided that there shall be no indemnification for: (i) amounts paid in
settling or otherwise disposing of a pending action without court approval; (ii)
expenses incurred in defending a pending action which is settled or otherwise
disposed of without court approval; (iii) matters in which such person shall
have been adjudged to be liable to the corporation unless and only to the extent
that the court in which the proceeding is or was pending shall determine that
such person is entitled to be indemnified; or (iv) other matters specified in
the California General Corporation Law.

     Sierra Bancorp's Bylaws provide that Sierra Bancorp shall to the maximum
extent permitted by law have the power to indemnify its directors, officers and
employees. Sierra Bancorp's Bylaws also provide that Sierra Bancorp shall have
the power to purchase and maintain insurance covering its directors, officers
and employees against any liability asserted against any of them and incurred by
any of them, whether or not Sierra Bancorp would have the power to indemnify
them against such liability under the provisions of applicable law or the
provisions of Sierra Bancorp's Bylaws.

ITEM 21.  Exhibits and Financial Statement Schedules

(a)  Exhibits.  See Exhibit Index

(b)  Financial Statement Schedules

     All schedules are omitted because the required information is not
     applicable.

(c)  Not applicable.

ITEM 22.  Undertakings

(a)  The undersigned Registrant hereby undertakes to file, during any period in
     which offers or sales are being made, a post-effective amendment to this
     Registration Statement:

     (i)   To include any prospectus required by Section 10(a)(3) of the
           Securities Act.

     (ii)  To reflect in the prospectus any facts or events arising after the
           effective date of the registration statement (or the most recent
           post-effective amendment thereof) which, individually or in the
           aggregate, represent a fundamental change in the information set
           forth in the registration statement. Notwithstanding the foregoing,
           any increase or decrease in volume of securities offered (if total
           dollar value of securities offered would not exceed that which was
           registered) and any deviation from the low or high end of the
           estimated maximum range may be reflected in the form of prospectus
           filed with the Commission pursuant to Rule 424(b) if, in the
           aggregate, the changes in volume and price

                                     II-1


           represent no more than 20 percent change in the maximum aggregate
           offering price set forth in the "Calculation of Registration Fee"
           table in the effective registration statement.

     (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in the registration statement
           or any material change to such information in the registration
           statement.

(b)  That, for the purpose of determining any liability under the Securities Act
     of 1933, each such post-effective amendment shall be deemed to be a new
     registration relating to the securities offered therein, and the offering
     of such securities at that time shall be deemed to be the initial bona fide
     offering.

(c)  To remove from registration by means of a post-effective amendment any of
     the securities being registered which remain unsold at the termination of
     the offering.

(d)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to directors, officers and controlling persons of
     the Registrant pursuant to the foregoing provisions, or otherwise, the
     Registrant has been advised that in the opinion of the Securities and
     Exchange Commission such indemnification is against public policy as
     expressed in the Act and is, therefore, unenforceable. In the event that a
     claim for indemnification against such liabilities (other than the payment
     by the Registrant of expenses incurred or paid by a director, officer or
     controlling person of the Registrant in the successful defense of any
     action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     Registrant will, unless in the opinion of its counsel the matter has been
