         issuable to holders of common stock of Six Rivers National Bank, a
         national banking association ("SRNB"), in the proposed merger of SRNB
         with the Registrant. Represents the approximate number of shares of
         common stock of the Registrant to be issued upon the consummation of
         the merger, based upon the number of shares of SRNB common stock
         outstanding on December 21, 1999 (including shares issuable upon the
         exercise of options pursuant to SRNB's stock option plan), all as
         provided in the Agreement and Plan of Reorganization and Merger dated

         statement/prospectus.

(2)      Pursuant to Rule 457(f), the registration fee was computed on the basis
         of $13.4375, the market value of the common stock of SRNB to be
         exchanged in the merger, computed in accordance with Rule 457(c) on the
         basis of the average of the high and low price per share of such stock
         as quoted on the Nasdaq National Market on December 21, 1999, and
         1,644,238, the maximum number of shares of SRNB which may be received
         by the Registrant and cancelled upon consummation of the plan of
         reorganization and merger described above.

         The Registrant hereby amends this Registration Statement on such date
or dates as may be necessary to delay its effective date until the Registrant
shall file a further amendment which specifically states that this Registration
Statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933 or until the Registration Statement shall become
effective on such date as the Commission, acting pursuant to said Section 8(a),
may determine.

Dear Shareholder:

         You are cordially invited to attend a special meeting of the
shareholders of North Valley Bancorp ("NVBancorp") to be held at [LOCATION],
Redding, California at ___:__ _.m., local time, on ___________, 2000.

Six Rivers National Bank ("SRNB") and NVB Interim National Bank, including the
merger of SRNB into NVB Interim National Bank, with the resulting national
banking association continuing under the name and national bank charter of SRNB.
You will also be asked to consider and vote on a proposal for the classification
of the NVBancorp board of directors. These proposals are more fully described in
the accompanying joint proxy statement/prospectus. The plan of reorganization is
attached to this document as Annex A. No other business will be transacted at

         As a result of the merger, each share of SRNB common stock outstanding
at the effective time of the merger (other than shares with respect to which

shares of NVBancorp common stock according to a conversion ratio based on the
average trading price of NVBancorp common stock prior to the closing, subject to
certain potential adjustments described in the plan of reorganization and the
accompanying joint proxy statement/prospectus. No fractional shares of NVBancorp
common stock will be issued to holders of shares of SRNB common stock. In lieu
of such fractional shares, cash will be paid to SRNB shareholders in accordance
with the terms of the plan of reorganization.

         Under the California General Corporation Law, the approval of the plan
of reorganization and the merger requires the affirmative vote of the holders of
a majority of the outstanding shares of NVBancorp common stock. The consummation
of the merger also requires that certain regulatory approvals be received and
that the conditions contained in the plan of reorganization be satisfied.

         THE NVBANCORP BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE PLAN OF
REORGANIZATION AND THE TRANSACTIONS CONTEMPLATED BY THE PLAN OF REORGANIZATION
INCLUDING THE MERGER, AND RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" APPROVAL
OF THE PLAN OF REORGANIZATION AND THE TRANSACTIONS CONTEMPLATED BY THE PLAN OF
REORGANIZATION, INCLUDING THE MERGER, AND "FOR" THE PROPOSAL FOR THE

             QUESTIONS AND ANSWERS ABOUT THE PLAN OF REORGANIZATION

         Q: WHY IS THIS PLAN OF REORGANIZATION AND MERGER PROPOSED?

         A: NVBancorp and SRNB are proposing this transaction because the boards
of directors have concluded that a combination of the two organizations is in
the best interests of shareholders of NVBancorp and SRNB and that the combined
companies can offer customers of NVBancorp, North Valley Bank and SRNB a broader
array of services and products than each could offer on its own.

         Q: WHAT WILL I RECEIVE IN THIS TRANSACTION?

         A: Under the plan of reorganization, SRNB shareholders will have the
right to receive a certain number of shares of NVBancorp common stock for each
share of SRNB common stock that they own according to a conversion ratio based
on the average trading price of NVBancorp common stock prior to the closing. The
conversion ratio will be equal to the average of the daily average of bid and
ask prices for NVBancorp shares on the Nasdaq National Market for the twenty
consecutive trading days ending on the third trading day immediately preceding
the effective time of the merger. Any fractional shares will be paid in cash.
NVBancorp shareholders will continue to own their existing shares.

         Q: WHAT HAPPENS AS THE MARKET PRICE OF NVBANCORP SHARES FLUCTUATE?

         A: The average closing price will determine the conversion ratio. For
instance, if the average closing price is not less than $10.00 and is not more
than $12.06, each SRNB share will be converted to 1.450 NVBancorp shares; if the
average closing price is not less than $12.07 and not more than $12.50, the
conversion ratio will be determined by dividing $17.50 by the average closing
price; and if the average closing price is more than $12.50 but is not more than
$15.00, the conversion ratio will be 1.400. If the average closing price is
greater than $15.00, then the conversion ratio will be determined in accordance
with a stated formula. If the average closing price is less than $10.00, then
the board of directors of SRNB may elect to terminate the plan of
reorganization; otherwise, the conversion ratio will be 1.450. See "Proposal to
Approve the Plan of Reorganization and Merger -Purchase Price and Potential
Adjustments" on page 49.

         Q: WHAT WILL HAPPEN TO SIX RIVERS NATIONAL BANK IN THIS PLAN OF
REORGANIZATION AND MERGER?

         A: SRNB will be merged into NVB Interim National Bank, an interim
national banking association formed by NVBancorp. The national banking
association resulting from this merger will continue under the name and national
bank charter of SRNB and will be a subsidiary of NVBancorp. NVBancorp will then
have two bank subsidiaries: North Valley Bank and Six Rivers National Bank.

         Q: WILL THE PLAN OF REORGANIZATION AND MERGER BE TAX FREE TO ME?

         A: The merger is intended to be a tax-free reorganization for federal
income tax purposes for the companies and their shareholders. In general, SRNB
shareholders will not recognize gain or loss on the exchange of their stock,
other than on account of cash received for fractional shares or dissenting
shares. NVBancorp shareholders will not recognize any gain or loss in connection
with the merger. To review the tax consequences to NVBancorp and SRNB
shareholders in greater detail, see "The Merger--Certain Federal Income Tax
Consequences" on page 67.

         Q: WHAT RISKS SHOULD I CONSIDER?

         A: You should carefully read the information set forth in this joint
proxy statement/prospectus and also consider certain other risk factors. See
"Risk Factors" on page 19.

                                       -1-
<PAGE>


         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 so that your shares may be represented at your special meeting. You may
choose to vote by telephone instead of by proxy card by calling the toll-free
telephone number indicated on the proxy card. See, "Introduction -- Voting of
Proxies -- SUBMITTING PROXIES" on page 29.

         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 that you follow the
directions provided by your broker regarding how to instruct your broker to vote
your shares. Your failure to instruct your broker on how to vote your shares
will have the same effect as a vote against any proposal, including the plan of
reorganization and merger. Broker non-votes and abstentions will not have the
effect of establishing dissenters' rights of NV Bancorp or SRNB shareholders.
See "Introduction - Voting of Proxies - ABSTENTIONS AND BROKER NON-VOTES" on
page 30.

         Q: CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD OR
VOTED BY TELEPHONE?

         A: Yes. If you vote by returning a proxy card, you may change your vote
at any time before your proxy is voted at the special 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 the
address at the top of the notice of the special meeting for SRNB or NVBancorp
(as appropriate) and it must be received prior to the vote at the special
meeting. Third, you may attend the special meeting and vote in person if you
tell the Secretary that you want to cancel your proxy and vote in person. Simply
attending the special 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 in person at the special
meeting. If you vote by telephone, you may change your vote at any time before
5:00 p.m., Eastern Standard Time on the day before the special meeting, by
calling the toll-free number indicated on the proxy card, or you may change your
vote by following any of the three alternatives described above. See,
"Introduction -- Voting of Proxies -- REVOKING PROXIES" on page 29.

         Q: SHOULD I SEND IN MY SRNB STOCK CERTIFICATES NOW?

         A: No. After the merger is completed, the exchange agent appointed by
NVBancorp will send you written instructions for exchanging your SRNB stock
certificates.

         Q: WHEN DO YOU EXPECT THE PLAN OF REORGANIZATION AND MERGER TO BE
COMPLETED?

         A: We are working toward completing this merger as quickly as possible.
We currently expect to complete this merger in March 2000.

         Q: WHY HAVE YOU SENT ME THIS DOCUMENT?

         A: This joint proxy statement/prospectus contains important information
regarding the proposed plan of reorganization and the merger, as well as
information about NVBancorp and SRNB. It also contains important information
about what the SRNB and NVBancorp boards of directors and management considered
in evaluating this proposed merger. We urge you to read this document carefully,

INFORMATION ABOUT NVBANCORP AND SRNB (pages 31 and 32)

         North Valley Bancorp
         880 East Cypress Avenue
         Redding, California  96002
         (530) 221-8400

         NVBancorp is a bank holding company incorporated under the laws of the
State of California and registered under the Bank Holding Company Act of 1956,
as amended. NVBancorp's banking subsidiary, North Valley Bank, is a California
banking corporation which presently operates 12 banking offices in Shasta and
Trinity Counties.

         North Valley Bank accepts checking and savings deposits, offers money
market deposit accounts and certificates of deposit, makes secured and unsecured
commercial and other installment and term loans and offers other customary
banking services. North Valley Bank offers banking services generally, but it
places primary emphasis on lending for real estate purposes and specialized
lending to businesses and professionals. Loans for real estate purposes include
term financing for commercial facilities and real estate construction loans
mainly for residential and commercial properties. Loans to businesses and
professionals include commercial loans, SBA loans, deposit services and letters
of credit. North Valley Bank's consumer financial services include residential
real estate loans, retail deposit services, mutual fund products and consumer
finance. As a bank holding company, NVBancorp is authorized to engage in the
activities permitted under the Bank Holding Act of 1956, as amended, and
regulations thereunder.

         Six Rivers National Bank
         402 "F" Street
         Eureka, California 95501
         (707) 443-8400

         SRNB is a national banking association, and a full service commercial
bank formed in 1989 and headquartered in Eureka, California, approximately 250
miles north of San Francisco. SRNB conducts a community banking business through
eight full-service offices in Eureka (2), Crescent City, Ferndale, Garberville,
McKinleyville, Weaverville and Willits. It concentrates on obtaining low-cost
core deposits from local customers and making primarily commercial, consumer and
real estate loans to local borrowers.

         SRNB is chartered under the laws of the United States and is governed
by the National Bank Act and the regulations promulgated thereunder. SRNB is a
member of the Federal Deposit Insurance Corporation, which currently insures the
deposits of each member bank to a maximum of $100,000 per depositor. For this
protection, SRNB pays a semi-annual assessment (currently set at a nominal
amount) and is subject to the rules and regulations of the Federal Deposit
Insurance Corporation pertaining to deposit insurance and other matters.

                                      -5-
<PAGE>


National banks are subject to regulation, supervision and regular examination by
the Office of the Comptroller of the Currency. The regulations of the Federal
Deposit Insurance Corporation and the Office of the Comptroller of the Currency
govern many aspects of SRNB's business and activities, including investments,
loans, borrowings, branching, mergers and acquisitions, reporting and numerous
other areas. All national banks are members of the Federal Reserve System. SRNB
is also subject to applicable provisions of California law to the extent those
provisions are not in conflict with or preempted by federal banking law.

         The geographic area served by SRNB is a rural market along California's
north coast and southern Oregon. SRNB's promotional activities stress its
specialized services and responsiveness to unique local needs.

         SRNB accepts checking and savings deposits, offers money market deposit
accounts and certificates of deposit, makes secured and unsecured commercial and
other installment and term loans, and offers other customary banking services.
SRNB also makes real estate loans that consist primarily of term and
construction financing for both businesses and individuals. Included in the
bank's commercial product line are loans to businesses and professionals for
accounts receivable financing, equipment financing, letters of credit and loans
that are partially guaranteed by the U.S. Government.

PURCHASE PRICE AND POTENTIAL ADJUSTMENTS (page 49)

         When the transactions contemplated by the plan of reorganization,
including the merger, are completed, it is expected that SRNB shareholders will
receive a number of NVBancorp shares of common stock for each share of SRNB
common stock held calculated in accordance with a conversion ratio. The
conversion ratio will be determined based on the average of the daily average of
bid and ask prices for NVBancorp shares on the Nasdaq National Market for the
twenty (20) consecutive trading days ending at the end of the third trading day
immediately preceding the effective time of the merger, rounded to four decimal
places (whether or not trades occurred on those days). If the average closing
price is not less than $10.00 and is not more than $12.06, the conversion ratio
will be 1.450; if the average closing price is not less than $12.07 and is not
more than $12.50, the conversion ratio will be determined by dividing $17.50 by
the average closing price; if the average closing price is more than $12.50 but
is not more than $15.00, the conversion ratio will be 1.400. If the average
closing price is less than $10.00, then the board of directors of SRNB may elect
to terminate the plan of reorganization; provided, however, that if SRNB does
not give NVBancorp timely notice of termination, then the conversion ratio will
be 1.450 and the merger closing will go forward. If the average closing price is
greater than $15.00, then the conversion ratio will be determined in accordance
with a formula calculated as follows: the conversion ratio will equal $21.00
PLUS 0.56 times the number equal to the average closing price MINUS $15.00, with
the sum DIVIDED by the average closing price. See "Proposal to Approve the Plan
of Reorganization and Merger--Purchase Price and Potential Adjustments" on page
49.

         No fractional shares of NVBancorp common stock will be issued to
holders of SRNB common stock. Instead, each holder entitled to a fraction of a
share will receive, at the time of surrender of the certificate or certificates
representing the holder's shares, an amount in cash equal to the market value
per share of the fractional shares. The market price will be based on the
closing price of NVBancorp shares on the Nasdaq National Market on the trading
day immediately preceding the effective time of the merger.

CONDITIONS TO COMPLETION OF THE MERGER (page 58)

         We will not complete the merger unless a number of conditions are
satisfied. These include:

         o    approval of the merger by both NVBancorp and SRNB shareholders;

         o    receipt of all required governmental approvals;

         o    absence of any governmental proceeding that would prohibit the
              merger;

         o    receipt of tax opinions to the effect that the merger will be
              treated as a tax-free reorganization under the Internal Revenue
              Code;

         o    absence of any orders suspending the effectiveness of the
              registration statement filed by NVBancorp to register the shares
              to be issued to SRNB shareholders and receipt of all required
              state securities law approvals;

         o    receipt of a letter from NVBancorp's independent accountants that
              no conditions exist that would preclude accounting for the merger
              as a pooling-of-interests and receipt of a letter from SRNB's
              independent accountants to the effect that no conditions exist
              that would preclude SRNB from being a party to a business
              combination to be accounted for as a pooling-of-interests;

         o    receipt of a written fairness opinion dated as of the date of this
              joint proxy statement/ prospectus from SRNB's and NVBancorp's
              financial advisors; and

         o    other customary conditions.

         NVBancorp or SRNB could decide to complete the merger even though one
or more of these conditions has not been met. It is not certain when or if the
conditions to the merger will be satisfied or waived, or if the merger will be
completed.

TERMINATION OF THE PLAN OF REORGANIZATION (page 61)

         We can terminate the plan of reorganization at any time before the
merger is completed, even if the shareholders of SRNB or NVBancorp have approved
the plan of reorganization. The plan of reorganization can be terminated either
by our mutual agreement or by one of us if certain events occur.

         Either SRNB or NVBancorp can terminate the plan of reorganization if:

         o    The merger is not completed by March 31, 2000, unless this date is
              extended under certain circumstances;

         o    Any governmental agency denies or refuses to grant a required
              approval of the merger, unless we agree to appeal the denial or
              refusal or we agree to file an amended application for the
              governmental approval; or

         o    The shareholders of SRNB or NVBancorp fail to approve the merger.

         NVBancorp can terminate the plan of reorganization if:

         o    Any of the conditions to NVBancorp's obligations under the plan of
              reorganization are not satisfied or waived by March 31, 2000
              unless this date is extended under certain circumstances;

         o    A material adverse change has occurred in the business, financial
              condition, results of operations or assets of SRNB;

         o    SRNB or any of its affiliates enters into an agreement by which
              SRNB or its subsidiaries would be acquired by another entity;

         o    SRNB breaches any covenant in the plan of reorganization which
              materially impairs the benefit of the merger to NVBancorp, unless
              SRNB cures the breach within 45 days after written notice from
              NVBancorp; or

         o    SRNB fails to deliver to NVBancorp certain documents required for
              the merger.

         SRNB can terminate the plan of reorganization if:

         o    Any of the conditions to SRNB's obligations under the plan of
              reorganization are not satisfied or waived by March 31, 2000,
              unless this date is extended under certain circumstances;

         o    A material adverse change has occurred in the business, financial
              condition, results of operations or assets of NVBancorp;

         o    NVBancorp solicits or accepts an offer from a third party to
              acquire NVBancorp or North Valley Bank and the offer does not
              require NVBancorp or the third party to comply with the plan of
              reorganization;

         o    NVBancorp breaches any covenant in the plan of reorganization
              which materially impairs the benefit of the merger to SRNB unless
              NVBancorp cures the breach within 45 days after receipt of written
              notice from SRNB; or

         o    NVBancorp fails to deliver to SRNB certain documents required for
              the merger.

         SRNB also has the option to terminate the plan of reorganization within
two business days after the determination date, if the average closing price of
NVBancorp common stock for the 20 trading days ending on the determination date
is less than $10.00. The determination date is the last day of the 20 trading
day period ending on the third business day prior to the closing date.

         SRNB is required to pay NVBancorp $2.0 million in liquidated damages if
NVBancorp terminates the plan of reorganization for any of the following

              or its subsidiaries would be acquired by another entity;

         o    If SRNB breaches any covenant in the plan of reorganization which
              materially impairs the benefit of the merger to NVBancorp, unless

              NVBancorp; or

         o    If SRNB willfully or deliberately refuses to deliver to NVBancorp
              certain closing documents required by the plan of reorganization.

         NVBancorp is required to pay SRNB $2.0 million in liquidated damages if
SRNB terminates the plan of reorganization for any of the following reasons:

         o    If NVBancorp solicits or accepts an offer from a third party to
              acquire NVBancorp or North Valley Bank and the offer does not
              require NVBancorp or the third party to comply with the plan of
              reorganization;

         o    If NVBancorp breaches any covenant in the plan of reorganization
              which materially impairs the benefit of the merger to SRNB, unless

              from SRNB; or

         o    If NVBancorp willfully or deliberately refuses to deliver to SRNB
              certain closing documents required by the plan of reorganization.

FEES AND EXPENSES OF THE MERGER (page 63)

         Other than in the situations described in "--Termination Fees" above
and for certain expenses which we have agreed to share equally, whether or not
the merger is completed in accordance with the plan of reorganization, all costs
and expenses incurred in connection with the plan of reorganization and the
transactions covered by the plan of reorganization will be paid by the party
incurring those expenses.

REASONS FOR THE MERGER; RECOMMENDATIONS OF THE BOARDS OF DIRECTORS (page 35)

         The boards of directors of NVBancorp and SRNB believe that the merger
is in the best interests of their respective institutions, shareholders,
communities and banking customers. Each board expects that NVBancorp, as a
larger organization in multiple and diverse markets, will be stronger in terms
of growth opportunities and profitability than is either institution at present.
NVBancorp will also have the advantage of consolidation and centralization of
certain management and operations functions and certain economies of scale.
Furthermore, it is believed that NVBancorp, as a stronger independent financial
institution with a primary market area covering a greater geographic area, will
be better able to compete with major banks in the communities now served by each
company.

RECOMMENDATIONS TO SHAREHOLDERS (page 35)

         NVBANCORP SHAREHOLDERS. The board of directors of NVBancorp believes
that the merger is fair to you and in your best interests and unanimously
recommends that you vote "FOR" the proposal to approve the plan of
reorganization and the merger and the issuance of shares of NVBancorp common
stock in connection with the merger. The board of directors also unanimously
recommends that you vote "FOR" the proposal for the classification of the
NVBancorp board of directors.

         SRNB SHAREHOLDERS. The board of directors of SRNB believes that the
merger is fair to you and in your best interests and unanimously recommends that
you vote "FOR" the proposal to approve the plan of reorganization and the
merger.

         In evaluating the recommendations of the boards of directors summarized
above, shareholders should carefully consider the matters described under "Risk
Factors" and "The Merger-Background of the Merger" and "Proposal to Approve the
Plan of Reorganization and Merger-Reasons for the Plan of Reorganization and
Merger; Recommendations of the Boards of Directors."

OPINION OF SRNB'S FINANCIAL ADVISOR (page 39)

         Hoefer & Arnett Incorporated has rendered an opinion, dated October 1,
1999 and updated to _____________, 2000, to the SRNB board of directors that the
plan of reorganization and merger is fair, from a financial point of view, to
the shareholders of SRNB, as of the date of the opinion. The Hoefer fairness
opinion, which sets forth certain assumptions made, matters considered and
limits of review undertaken, by Hoefer & Arnett Incorporated, is attached to
this joint proxy statement/prospectus as Annex B. SRNB shareholders are urged to
read the Hoefer fairness opinion in its entirety. See "Proposal to Approve the
Plan of Reorganization and Merger--Opinion of SRNB's Financial Advisor" on page
39, which also contains a discussion of the fees to be paid to Hoefer & Arnett
Incorporated. Certain of the fees to be paid to Hoefer & Arnett Incorporated are
contingent upon consummation of the merger. If Hoefer & Arnett Incorporated does
not render an updated fairness opinion dated the date of this joint proxy
statement/prospectus, the plan of reorganization can be terminated.

OPINION OF NVBANCORP'S FINANCIAL ADVISOR (page 44)

         Alex Sheshunoff & Co. Investment Banking, L.P. has rendered an opinion,
dated September 23, 1999 and updated to _____________, 2000, to NVBancorp's
board of directors that the plan of reorganization and merger is fair, from a
financial point of view, to the holders of NVBancorp common stock. The opinion
of Alex Sheshunoff & Co. Investment Banking L.P. is attached to this joint
proxy/prospectus as Annex C.

ACCOUNTING TREATMENT (page 68)

         NVBancorp expects to account for the merger as a "pooling of
interests." Under the pooling of interests accounting method, NVBancorp will
carry forward on its books the assets and liabilities of SRNB at their
historical recorded values.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES (page 67)

         The plan of reorganization and merger has been structured so that, in
general, NVBancorp and SRNB and the shareholders of NVBancorp and SRNB will not
recognize gain or loss for federal income tax purposes in the merger, except for
taxes payable because of cash received by SRNB shareholders instead of
fractional shares or because of dissenting shares. It is a condition, at the
closing of the merger, that NVBancorp and SRNB receive an opinion from tax
counsel to the effect, among other matters, that the merger should qualify as a
tax-free reorganization.

         TAX MATTERS ARE VERY COMPLICATED. THE TAX CONSEQUENCES OF THE MERGER TO
YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. WE URGE YOU TO CONSULT YOUR
OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING
THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS.

INTERESTS OF CERTAIN PERSONS IN THE MERGER (page 52)

         Some of SRNB's directors and officers may have interests in the merger
that are different from, or in addition to, yours. As a result, these directors
and officers may be more likely to vote to approve the plan of reorganization
and the merger than shareholders of SRNB generally. The members of our boards of
directors knew about these additional interests, and considered them, when they
approved the transactions contemplated by the plan of reorganization, including
the merger. See "Introduction-Share Ownership of Management" and "Proposal to
Approve the Plan of Reorganization and Merger--Interests of SRNB Officers and
Directors in the Merge" on page 52.

DISSENTERS' RIGHTS (page 69)

         NVBANCORP. No holder of NVBancorp common stock will be entitled to
dissenters' rights unless the holders of at least 5% of the outstanding shares
of NVBancorp common stock have perfected their dissenters' rights in accordance
with Chapter 13 of the California General Corporation Law.

         SRNB. No holder of SRNB common stock will be entitled to dissenters'
rights unless the holder has perfected his or her dissenter's rights in
accordance with applicable provisions of the National Bank Act.

COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION (page 80)

         NVBancorp common stock is listed and traded on the Nasdaq National
Market under the symbol "NOVB." SRNB common stock is quoted on the Nasdaq
National Market under the symbol "SIXR." On October 1, 1999, the last trading
date prior to the public announcement of the proposed merger, NVBancorp common
stock closed at $11.063 per share and SRNB common stock closed at $13.50 per
share, or a pro forma equivalent per share of NVBancorp common stock (based on
an conversion ratio of ____) of $_____. On __________, 2000, the latest
practicable trading date prior to the printing of this joint proxy
statement/prospectus, NVBancorp common stock closed at $________ per share and
SRNB common stock closed at $________ per share, or a pro forma equivalent per
share of NVBancorp common stock (based on an conversion ratio of ___) of
$________. Following the merger, no shares of SRNB common stock will be
outstanding and NVBancorp common stock will continue to be traded on the Nasdaq
National Market.

         NVBancorp has paid cash dividends to its shareholders on a semi-annual
basis from 1993 through 1997 and on a quarterly basis commencing with the first
quarter of 1998. NVBancorp paid cash dividends totaling $.35 per share in 1997,
$.375 per share in 1998 and $.30 per share through September 30, 1999. It is the
intention of NVBancorp to pay cash dividends, subject to certain regulatory
restrictions and depending upon the level of earnings, management's assessment
of future capital needs and other factors considered by the NVBancorp board of
directors. SRNB has not paid cash dividends in 1997, 1998 or 1999. SRNB does not
intend to pay cash dividends prior to the closing of the transactions
contemplated by the plan of reorganization.

COMPARISON OF SHAREHOLDER RIGHTS (page 83)

         Your rights as a shareholder of SRNB are currently governed by the
National Bank Act, California law and the articles of association and bylaws of
SRNB. If the merger is completed, your rights as a NVBancorp shareholder will be
governed by California law but will also be determined by NVBancorp's articles
of incorporation and bylaws, which differ in certain respects from SRNB's
articles of association and bylaws.

FORWARD-LOOKING STATEMENTS (page 22)

         Statements in this document and in the documents incorporated here by
this reference are or may be forward-looking statements that involve risks and
uncertainties. Actual results may differ materially from those expressed in the
statements, depending on a variety of factors. You should carefully review all
information, including the financial statements and the notes to the financial
statements, included or incorporated here by this reference.

SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA (page 72)

         We are providing the following information to aid you in your analysis
of the financial effects of the merger. The following tables show financial
results actually achieved by each of NVBancorp and SRNB (the "historical"
figures). The tables also show results as if the companies had been combined for
the periods presented (the "pro forma combined" figures). Pro forma combined
figures are simply arithmetical combinations of NVBancorp's and SRNB's separate
financial results; you should not assume that NVBancorp and SRNB would have
achieved the pro forma combined results if they had actually been combined
during the periods presented. These pro forma presentations treat our companies
as if they had always been combined for accounting and financial reporting
purposes, a method known as pooling of interests accounting, which is how we
plan to account for the merger. When you read this information, you should also
read the information under the heading "Unaudited Pro Forma Condensed Combined
Financial Information" on page 72. For purposes of illustration, the pro forma
combined figures have been calculated using the conversion ratio of 1.450. The
actual conversion ratio could be adjusted as described under the heading
"Proposal to Approve the Plan of Reorganization and Merger-Purchase Price and
Potential Adjustments" on page 49.

         The financial information as of and for the nine months ended September
30, 1999 and 1998 has been derived from the unaudited consolidated financial
statements of NVBancorp and the unaudited financial statements of SRNB. In the
opinion of management of NVBancorp and SRNB, respectively, all adjustments
(consisting of normal recurring accruals) considered necessary for the fair
presentation of the results for the periods presented have been included. Annual
historical figures are derived from the consolidated financial statements of
NVBancorp and the financial statements of SRNB as of December 31, 1998 and 1997
and for the three years then ended audited by Deloitte & Touche LLP, independent
auditors of NVBancorp and SRNB. The historical figures for the other years
presented have been derived from the audited consolidated financial statements
of NVBancorp and the audited financial statements of SRNB. The annual historical
information presented below should be read together with the consolidated
audited financial statements of NVBancorp, incorporated here by this reference,
and the audited financial statements of SRNB, incorporated here by this
reference. To find this information, see "Where You Can Find More Information"
on page 97.

         We expect to incur merger and other non-recurring expenses as a result
of combining our companies. We also anticipate that the merger will provide the
combined company with financial benefits such as reduced operating expenses and
the opportunity to earn additional revenue. However, none of these anticipated

                                      -13-
<PAGE>


expenses or benefits has been factored into the pro forma combined income
statement information. For that reason, the pro forma combined information,
while helpful in illustrating the financial attributes of the combined company
under one set of assumptions, does not attempt to predict or suggest future
results.

         The following tables present selected historical and pro forma combined
consolidated financial information for NVBancorp and SRNB. The following
financial data should be read in conjunction with the historical consolidated
financial statements of NVBancorp, the historical consolidated financial
statements of SRNB, and the unaudited pro forma combined consolidated financial
information and the notes to such information, certain of which are included
elsewhere in this joint proxy statement/prospectus. The unaudited pro forma
combined consolidated financial information presents selected financial
information based on the historical financial statements of the parties, giving
effect to the proposed merger under the pooling of interests method of
accounting and the assumptions and adjustments described in the notes thereto.
The unaudited pro forma combined consolidated financial information does not
indicate the results or financial position that would have occurred if the plan
of reorganization and merger had been in effect for the periods or on the dates
indicated or that may occur in the future.

         HISTORICAL AND PRO FORMA PER SHARE DATA FOR NVBANCORP AND SRNB

         We have summarized below the per share information for our respective
companies on a historical, pro forma combined and equivalent basis.

         We have calculated the pro forma combined per share data for net income
using the weighted average number of shares of NVBancorp's common stock
outstanding for the periods presented, increased by the weighted average number
of shares of SRNB common stock outstanding for the periods presented multiplied
by an assumed conversion ratio of 1.450 shares of NVBancorp's common stock for
each share of SRNB common stock, as if these shares were outstanding for each
period presented. The pro forma combined per share data for dividends declared
represents the historical dividends for NVBancorp common stock. The pro forma
combined book value per share has been calculated using shares of outstanding
NVBancorp common stock increased by the shares of outstanding SRNB common stock
multiplied by an assumed conversion ratio of 1.450 for each share of SRNB common
stock as if these shares were outstanding as of the dates presented.

         The equivalent pro forma SRNB share information has been calculated by
multiplying the pro forma combined per share information by an assumed
conversion ratio of 1.450.

                                  RISK FACTORS

         In deciding whether to vote in favor of the merger, shareholders of
SRNB and NVBancorp should consider the following factors, in addition to the
other matters set forth or incorporated here by this reference:

THE PRICE OF NVBANCORP COMMON STOCK MAY DECLINE

         The conversion ratio may be affected by potential changes in the market
price of NVBancorp common stock. This means that at the time of the special
meetings, the SRNB shareholders will not know the exact conversion ratio and
value of the NVBancorp common stock that they will receive when the merger is
completed. The market price of NVBancorp common stock when the merger takes
place may vary from the price at the date of this document and at the date of
the special meetings. Variations in the market price of NVBancorp common stock
may result from changes in the business, operations or prospects of NVBancorp,
SRNB or the combined company, market assessments of the likelihood that the
merger will be consummgated and the timing thereof, regulatory considerations,
general market and economic conditions and other factors. We urge you to obtain
current market quotations for NVBancorp common stock. See "Proposal to Approve
the Plan of Reorganization and Merger--Purchase Price and Potential Adjustments"
on page 49. Changes in the market price of SRNB common stock will not affect
the conversion ratio.

CUSTOMERS OF SRNB MAY NOT BE RETAINED AND NVBANCORP MAY NOT BE ABLE TO REALIZE
ANTICIPATED OPERATING COST SAVINGS

         Upon the consummation of the merger, SRNB will be merged with and into
NVB Interim National Bank, and the resulting national banking association will
continue as a subsidiary of NVBancorp with the national bank charter number and
name of Six Rivers National Bank. NVBancorp anticipates that, after the
effective time of the merger, a significant percentage of SRNB's existing
employees and customers will be retained. There are no assurances that SRNB
customers will not move their banking relationships to other financial
institutions and that a greater than anticipated number of SRNB employees will
not remain employed by SRNB after the merger. In addition, while NVBancorp
expects to achieve operating cost savings through the elimination of duplicative
corporate and administrative expenses and the consolidation of certain banking
operations, there can be no assurance that NVBancorp will be able to realize
those cost savings.

ADDITIONAL SHARES OF NVBANCORP COMMON STOCK COULD BE ISSUED WHICH COULD RESULT
IN A DECLINE IN THE MARKET PRICE OF THE STOCK

         Shares of NVBancorp common stock eligible for future sale could have a
dilutive effect on the market for NVBancorp common stock and could adversely
affect the market price. The articles of incorporation of NVBancorp authorize
the issuance of 20,000,000 shares of common stock, of which _________ shares
were outstanding at ______________, 2000 and 5,000,000 shares of preferred
stock, of which no shares were outstanding at ______________, 2000. Pursuant to
its stock option plan, at ______________, 2000, NVBancorp had outstanding
options to purchase an aggregate of __________ shares of NVBancorp common stock.
As of ______________, 2000, _________ shares of NVBancorp common stock remained
available for option grants under NVBancorp's stock option plans. The plan of
reorganization does not restrict NVBancorp's ability to grant additional options
under NVBancorp's stock option plan or with respect to a takeover proposal to
which NVBancorp is a party. See "The Merger--Purchase Price and Potential
Adjustments" on page 49.  Sales of substantial amounts of NVBancorp common stock
in the public market following the merger could adversely affect the market
price of NVBancorp common stock. There are no restrictions in the plan of
reorganization preventing NVBancorp from issuing additional shares of NVBancorp
common stock after the merger.

                                      -19-

         There can be no assurance given as to the market value of NVBancorp
common stock after the merger based on future acquisitions, if any, or other
factors, including but not limited to, general economic conditions or
fluctuating interest rates.

THE YEAR 2000 PROBLEM MAY ADVERSELY AFFECT NVBANCORP, SRNB OR THE RESULTING BANK

         The "Year 2000 issue" relates to the fact that many computer programs
and other technology utilizing microprocessors use only two digits to represent
a year, such as "98" to represent "1998." In the year 2000 ("Y2K"), those
programs/processors could incorrectly treat the year 2000 as the year 1900. This
issue has grown in importance as the use of computers and microprocessors has
become more pervasive throughout the economy, and interdependencies between
systems has multiplied. The business of NVBancorp and SRNB is dependent on
technology and data processing. NVBancorp and SRNB could be affected either
directly or indirectly by the Year 2000 issue. This could happen if any of their
respective critical computer systems or equipment containing embedded logic
fail, if the local infrastructure (electric power, communications or water
system) fails, if their respective significant vendors are adversely impacted,
or if their respective borrowers or depositors are significantly impacted by
their internal systems or those of their customers or suppliers.

         The business of NVBancorp and SRNB also involves non-information
technology ("IT") products and services, some of which have embedded technology
which might not be Year 2000 compliant. Some non-IT products and services
involve various infrastructure issues, such as power, communications and water,
as well as elevators, ventilation and air conditioning equipment.

         Failure to successfully complete renovation, validation and
implementation of mission-critical IT systems could have a material adverse
effect on the operations and financial performance of NVBancorp or SRNB.
Moreover, Year 2000 problems experienced by significant vendors or customers of
NVBancorp or SRNB or power or communications systems could negatively impact the
business and operations of NVBancorp and SRNB even if their own critical IT
systems are capable of functioning satisfactorily.

         Due to the numerous issues and problems which might arise and the lack
of guarantees concerning Year 2000 readiness from non-IT service providers, such
as power and communication systems vendors, NVBancorp and SRNB cannot quantify
the potential cost of problems if their respective renovation and implementation
efforts or the efforts of significant vendors or customers are not successful.
As a result, Year 2000 problems experienced by NVBancorp or SRNB or their
respective vendors or customers may adversely affect the business, financial
condition or results of operations of NVBancorp, SRNB or the resulting bank.

THE RESTRICTIONS OF THE OFFICE OF THE COMPTROLLER OF THE CURRENCY CONSENT ORDER
ENTERED INTO BY SRNB MAY HINDER PLANS

         On April 12, 1999 the Office of the Comptroller of the Currency
required SRNB to enter into a Consent Order. The language of the Order requires
that SRNB formulate and implement a plan to strengthen its policies and
procedures relative to its loan administration, credit and collateral
exceptions, classified assets, allowances for loan losses and violations of law
related to lending limits. The SNRB board of directors agreed to execute the
Order and is following an action plan that details the steps necessary to comply
with the Order. In summary, the Order required SRNB to modify certain aspects of

                                      -20-
<PAGE>


its business to address problems identified by the Office of the Comptroller of
the Currency, such as:

         o    loan administration (to establish procedures to ensure compliance
              with credit quality guidelines, govern board of directors review
              and approval of exceptions to lending policies, require periodic
              board of directors review of adherence to lending policies and
              ensure accuracy of information systems and other operational
              programs);

         o    credit and collateral exceptions (to update background information
              on each loan);

         o    criticized assets (to address issues raised by the Office of the
              Comptroller of the Currency during the evaluation and analysis of
              SRNB's asset quality and provide ongoing board of directors review
              of each issue and the adequacy and progress of SRNB's ongoing
              monitoring of asset quality);

         o    allowance for loan and lease losses (to establish a program to
              maintain adequate allowances providing for scheduled reviews by
              the board of directors);

         o    legal lending limits (to take prompt action to reduce overlimit
              loans and establish compliance procedures regarding the
              maintenance of appropriate loan limits); and

         o    quarterly progress reports (to submit quarterly progress reports
              to the Office of the Comptroller of the Currency outlining recent
              actions taken to implement the Order).

The Order's restrictions could have an adverse impact on SRNB's expansion.
Additional regulatory restrictions could be placed on SRNB in the event that the
Office of the Comptroller of the Currency is not satisfied with SRNB's progress
towards implementing all facets of the Order. There can be no assurance as to
the impact on SRNB or NVBancorp if banking regulators impose additional
regulatory restrictions on SRNB.

         No assurance can be provided as to when, if ever, the Order will be
removed by the Comptroller of the Currency, whether as a result of the merger or
otherwise. Likewise, no assurance can be provided regarding the impact of the
Order on the regulatory approvals required for the merger. See "Proposal to
Approve the Plan of Reorganization and Merger --Required Regulatory Approvals"
on page 64.

         This summary description of the Order's provisions does not state all
the requirements of the Order and is qualified in its entirety by reference to
the text of the Order. A copy of the Order will be made available (free of
charge) to any shareholder of NVBancorp or SRNB upon request to Michael W.
Martinez, President and Chief Executive Officer of SRNB. See "Where You Can Find
More Information." on page 97.

                INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

         This joint proxy statement/prospectus contains forward-looking
statements regarding each of NVBancorp and SRNB and the combined company
following the merger, including statements relating to:

         o    the financial condition, results of operations and business of
              NVBancorp following completion of the merger,

         o    cost savings, enhanced revenues and accretion to reported earnings
              that are expected to be realized from the merger, and

         o    the restructuring charges expected to be incurred in connection
              with the merger.

         These forward-looking statements involve certain risks and
uncertainties. Factors that may cause actual results to differ materially from
those contemplated by the forward-looking statements include, among others, the
following possibilities:

         o    expected cost savings from the merger cannot be fully realized or
              realized within the expected time frame;

         o    revenues following the merger are lower than expected or deposit
              withdrawals, operating costs or customer loss and business
              disruption following the merger may be greater than expected;

         o    competitive pressures among depository and other financial
              services companies increase significantly;

         o    costs or difficulties related to the integration of the businesses
              of NVBancorp and SRNB are greater than expected;

         o    changes in the interest rate environment reduce interest margins,
              cause an increase in the prepayment rate on mortgages and other
              loans or reduce the demand for new loans;

         o    general economic or business conditions, either internationally,
              nationally or in the states in which the combined company will be
              doing business, are less favorable than expected, resulting in,
              among other things, a deterioration in credit quality or a reduced
              demand for credit;

         o    legislation or regulatory requirements or changes adversely affect
              the businesses in which the combined company would be engaged;

         o    technology-related changes, including "Year 2000" data systems
              compliance issues, may be harder to make or more expensive than
              expected;

         o    changes in the securities market; and

         o    timing of completion of the merger may be delayed, due to
              regulatory requirements or other factors which may delay, restrict
              or prohibit new operations.

                                      -22-

         With respect to estimated cost savings, NVBancorp has made certain
assumptions regarding, among other things, the extent of operational overlap
between NVBancorp, North Valley Bank and SRNB, the amount of general and
administrative expense consolidation, costs relating to converting SRNB bank
operations and data processing to NVBancorp systems, the size of anticipated
reductions in fixed labor costs, the amount of severance expenses, the extent of
the charges that may be necessary to align the companies' respective accounting
reserve policies and the costs related to the merger. The realization of the
expected cost savings are subject to the risk that the foregoing assumptions are
inaccurate.

         Management of NVBancorp believes these forward-looking statements are
reasonable; however, undue reliance should not be placed on the forward-looking
statements, which are based on current expectations.

         Forward-looking statements are not guarantees of performance. They
involve risks, uncertainties and assumptions. The future results and shareholder
values of NVBancorp following completion of the merger may differ materially
from those expressed in these forward-looking statements. Many of the factors
that will determine these results and values are beyond NVBancorp's and SRNB's
ability to control or predict. For those statements, NVBancorp and SRNB claim
the protection of the safe harbor for forward-looking statements contained in
the Private Securities Litigation Reform Act of 1995.

VOTING OF PROXIES

         SUBMITTING PROXIES. NVBancorp and SRNB shareholders may vote their
shares in person by attending their respective special meeting or vote their
shares by proxy by completing the enclosed proxy card, signing and dating it and
mailing it in the enclosed postage pre-paid envelope, or by telephone, by
calling the toll-free number (at no cost to the shareholder) indicated on the
proxy card. Telephone voting is available 24 hours per day. Easy to follow voice
prompts allow a shareholder to vote shares and to confirm that instructions have
been properly recorded. The telephone voting procedures are designed to
authenticate the identity of shareholders by utilizing individual control
numbers. IF A SHAREHOLDER VOTES BY TELEPHONE, THERE IS NO NEED TO RETURN THE
PROXY CARD.

If a written proxy card is signed by a shareholder and returned without
instructions, the shares represented by the proxy will be voted "FOR" the
proposals presented at NVBancorp's special meeting or "FOR" the proposal
presented at SRNB's special meeting, as applicable. NVBancorp and SRNB
shareholders whose shares are held in "street name" (i.e., in the name of a
broker, bank or other record holder) must either direct the record holder of
their shares as to how to vote their shares or obtain a proxy from the record
holder to vote at their respective special meeting.

         REVOKING PROXIES. NVBancorp and SRNB shareholders of record may revoke
their proxies at any time before the time their proxies are voted at NVBancorp's
special meeting or SRNB's special meeting, respectively. Proxies may be revoked
by written notice, including by telegram or telecopy, to the Corporate Secretary
of NVBancorp or SRNB, as applicable, by a later-dated proxy signed and returned
by mail or by attending NVBancorp's special meeting or SRNB's special meeting,
as applicable, and voting in person. Attendance at NVBancorp's special meeting
or SRNB's special meeting will not in and of itself constitute a revocation of a
proxy. The shareholder must inform the secretary at the special meeting, prior
to the vote, that he or she wants to revoke his or her proxy and vote in person.
Any written notice of a revocation of a proxy must be sent so as to be received
before the taking of the vote at the applicable special meeting as follows:

                                      -29-
<PAGE>


For NVBancorp Shareholders, to:                    For SRNB Shareholders, to:

North Valley Bancorp                               Six Rivers National Bank
880 East Cypress Avenue                            402 "F" Street
Redding, California 96002                          Eureka, California 95501

If you vote by telephone, you may change your vote at any time before 5:00 p.m.
Eastern Standard Time on the day before the special meeting by calling the
toll-free number indicated on the proxy card. You may also change your vote by
following any of the procedures for revoking proxies described above. In all
cases, the latest dated proxy revokes an earlier dated proxy regardless of
whether mail or telephone is used to give or revoke a proxy, or whether mail and
telephone are used to give and revoke a proxy.

         ABSTENTIONS AND BROKER NON-VOTES. The presence, in person or by
properly executed proxy, of the holders of a majority of the outstanding shares
is necessary to constitute a quorum at each of NVBancorp's special meeting and
SRNB's special meeting. Abstentions and broker non-votes (as described below)
will be counted solely for the purpose of determining whether a quorum is
present. Under the applicable rules of the National Association of Securities
Dealers, Inc., brokers or members who hold shares in street name for customers
who are the beneficial owners of the shares are prohibited from giving a proxy
to vote those shares with respect to the approval of the transactions
contemplated by the plan of reorganization including the merger in the absence
of specific instructions from the customers. We refer to these as "broker
non-votes". Abstentions and broker non-votes will not be counted as a vote "FOR"
or "AGAINST" any proposal at either the NVBancorp special meeting or the SRNB
special meeting but will have the same effect as a vote "AGAINST" any proposal.
Abstentions and broker non-votes will not have the effect of establishing
dissenters' rights of NVBancorp or SRNB shareholders. See "Dissenters' Rights"
on page 69.

         If any other matters are properly presented for consideration at
NVBancorp's special meeting, in the case of the NVBancorp shareholders, or at
SRNB's special meeting, in the case of the SRNB shareholders, the persons named
in the enclosed form of proxy will have discretion to vote or not vote on those
matters in accordance with their best judgment, unless authorization to use that
discretion is withheld. If a proposal to adjourn NVBancorp's special meeting or
SRNB's special meeting is properly presented, however, the persons named in the
enclosed form of proxy will not have discretion to vote in favor of the
adjournment proposal any shares which have been voted against the proposal(s) to
be presented at the respective special meetings.

         Neither NVBancorp nor SRNB is aware of any matters expected to be
presented at their respective special meeting other than as described in their
respective notice of special meetings. The cost of solicitation of proxies will
be paid by NVBancorp and SRNB, as applicable. In addition to solicitation by
mail, the directors, officers and employees of NVBancorp and SRNB may also
solicit proxies from shareholders by telephone, facsimile, telegram or in
person. Arrangements will also be made with brokerage houses and other
custodians, nominees and fiduciaries to send the proxy materials to beneficial
owners; and NVBancorp or SRNB, as the case may be, will, upon request, reimburse
those brokerage houses and custodians for their reasonable expenses in so doing.
SRNB has retained Skinner & Co. of San Francisco, California, to aid in the
solicitation of proxies and to verify certain records related to the
solicitations. Skinner & Co. will receive $5,000 as compensation for its
services and up to $5,000 as reimbursement for its related out-of-pocket
expenses. NVBancorp does not intend to retain a proxy solicitor.

         Shareholders who submit proxy cards should not send in any stock
certificates with their proxy cards. Instructions for the surrender of
certificates representing shares of SRNB common stock will be mailed by
NVBancorp to former SRNB shareholders shortly after the merger is completed. See
"The Merger--Exchange of SRNB Stock Certificates; Fractional Interests" on page
51.

         SRNB is chartered under the laws of the United States and is governed
by the National Bank Act and the regulations promulgated thereunder. SRNB is a
member of the Federal Deposit Insurance Corporation, which currently insures the
deposits of each member bank to a maximum of $100,000 per depositor. For this
protection, SRNB pays a semi-annual assessment (currently set at a nominal
amount) and is subject to the rules and regulations of the Federal Deposit
Insurance Corporation pertaining to deposit insurance and other matters.
National banks are subject to regulation, supervision and regular examination by
the Office of the Comptroller of the Currency. The regulations of the Federal
Deposit Insurance Corporation and the Office of the Comptroller of the Currency
govern many aspects of SRNB's business and activities, including investments,
loans, borrowings, branching, mergers and acquisitions, reporting and numerous
other areas. All national banks are members of the Federal Reserve System. SRNB
is also subject to applicable provisions of California law to the extent the
provisions are not in conflict with or preempted by federal banking law.

         On November 6, 1997, SRNB completed the purchase and conversion of four
branches of Bank of America. The acquisition of the four branches increased
SRNB's size from four locations to eight and increased its presence outside of
Humboldt and Del Norte counties to Trinity County to the northeast and Mendocino
County to the south. In order to finance the purchase of the branches SRNB
completed a secondary stock offering in the fourth quarter of 1997, netting
approximately $13.2 million on the sale of 862,500 shares of SRNB's common
stock.

         At December 31, 1998, SRNB had total assets of $203.2 million, total
net loans of $104.2 million, deposits of $182.9 million and shareholders' equity
of $18.5 million. SRNB competes with approximately 13 other banking or savings
institutions in its service areas. SRNB's market share of Federal Deposit
Insurance Corporation-insured deposits in the four-county service area of
Humboldt, Del Norte, Mendocino and Trinity counties is approximately 8.3% at
December 31, 1998 (based upon information made available by the Federal Deposit
Insurance Corporation through June 30, 1998).

         The geographic area served by SRNB is a rural market along California's
north coast and southern Oregon. SRNB's promotional activities stress its
specialized services and responsiveness to unique local needs.

         SRNB accepts checking and savings deposits, offers money market deposit
accounts and certificates of deposit, makes secured and unsecured commercial and
other installment and term loans, and offers other customary banking services.
SRNB also makes real estate loans that consist primarily of term and
construction financing for both businesses and individuals. Included in the
bank's commercial product line are loans to businesses and professionals for
accounts receivable financing, equipment financing, letters of credit and loans
that are partially guaranteed by the U.S. Government.

         On April 12, 1999 the Office of the Comptroller of the Currency
required SRNB to enter into a Consent Order ("Order"). The language of the Order
requires that SRNB formulate and implement a plan to strengthen its policies and
procedures relative to its loan administration, credit and collateral
exceptions, classified assets, allowances for loan losses and violations of law
related to lending limits. The SRNB board of directors has agreed to execute
this Order and is following an action plan that details the steps necessary to
comply with the Order. See "Risk Factors -- The Restrictions of the Office of
the Comptroller of the Currency Consent Order Entered Into by SRNB May Hinder
Plans" and "Proposal to Approve the Plan of Reorganization and Merger --
Required Regulatory Approvals" on page 64.

            PROPOSAL TO APPROVE THE PLAN OF REORGANIZATION AND MERGER

BACKGROUND OF THE PLAN OF REORGANIZATION AND MERGER

         The following is a brief description of the events that resulted in the
execution of the Agreement and Plan of Reorganization and Merger dated as of
October 3, 1999 among NVBancorp, NVB Interim National Bank and SRNB.

         During 1998, the board of directors of SRNB focused its efforts on
attempting to resolve certain regulatory issues, primarily related to credit
quality and management, that were plaguing SRNB. Given the nature of the
problems and the time and effort the board was devoting to them, the board did
not consider it feasible to pursue a sale of SRNB. In December 1998, Humboldt
Bancorp initiated a series of communications to SRNB expressing interest in a
merger. Initially, SRNB responded to Humboldt through its representatives that
merger discussions were currently inadvisable because SRNB's board and
management were focusing on resolving operating problems.

         On January 11, 1999, Humboldt wrote to William Kay, Jr., Chairman of
the SRNB board of directors, indicating Humboldt's interest in pursuing a
possible transaction with SRNB. SRNB's board discussed this proposal at its
January meeting, but continued to believe that the timing was not appropriate to
pursue a transaction either with Humboldt or with any other institution. In
early February, Humboldt requested a meeting to discuss its interest. The board
considered the request at its February meeting and agreed to the meeting. The
board also considered a valuation review conducted by its financial adviser
which informed the board concerning the elements that affect stock value,
valuation methodologies and the ranges of values which could be achieved by
SRNB. The meeting between SRNB and Humboldt representatives occurred on March 3,
1999. The SRNB representatives again expressed the view that it would be
inappropriate to pursue a merger at that time.

         In spite of the stated position of the SRNB representatives, Humboldt
followed with a letter that was considered by SRNB at its March meeting. SRNB's
board reviewed the March 9, 1999 letter from Humboldt which outlined the terms
of Humboldt's proposal. The proposal by Humboldt contained a number of
unacceptable conditions that raised questions as to whether or not the proposal
actually constituted an offer. These and other questions regarding the valuation
of Humboldt's common stock led SRNB to respond that it would continue to pursue
shareholder value through the continuing focus by the board and management on
implementing SRNB's own independent business plan.

         Thereafter, an exchange of correspondence occurred between Humboldt and
SRNB which culminated in Humboldt publishing an open letter in the Eureka press
on May 12, 1999, the day of SRNB's annual meeting of shareholders, publicizing
its previously confidential offer.

         Following SRNB's annual meeting, the board appointed a strategic
planning committee to investigate SRNB's strategic options, including the
Humboldt proposal. The committee met frequently commencing on May 17, 1999 and
conferred regularly with SRNB's financial and legal advisers. The committee
directed SRNB's financial adviser to contact other institutions that may have an
interest in a business combination with SRNB to explore their level of interest.
The committee monitored the progress of those contacts.

         In the course of initial discussions with a broad range of
institutions, numbering in excess of 15 banks and holding companies, SRNB's
investment adviser identified two institutions, including NVBancorp, that
expressed very serious interest in exploring the possibility of a business
combination. Members of the strategic planning committee met with board and
management representatives of these parties. In mid-June, 1999, SRNB entered

                                      -33-
<PAGE>


into confidentiality agreements with these parties (including NVBancorp) and
disclosed to them non-public information concerning SRNB to assist them in their
evaluation of a possible transaction. At its June meeting, legal counsel gave
detailed advice to the SRNB board concerning the board's fiduciary
responsibilities in light of the Humboldt proposal and the interest of other
parties. After the meeting, SRNB formally engaged Hoefer & Arnett Incorporated
as its investment bank to evaluate the merits of remaining independent compared
with the opportunities for a business combination.

         On July 8, 1999 Humboldt again sent a letter communicating its desire
to negotiate a business combination with SRNB. After considering this letter,
the SRNB board responded by asking for answers to various significant business
concerns about the practices and strategies of Humboldt. Humboldt refused to
provide any responses to these questions unless SRNB executed a confidentiality
agreement granting special rights to Humboldt that SRNB believed would have
significantly reduced the effectiveness of such agreements and could have led to
the compromise of information that is proprietary to SRNB and its operations. In
response, SRNB proposed a standard confidentiality and standstill agreement,
similar to those that had been signed by other institutions, however this was
rejected by Humboldt. On August 20, 1999, Humboldt revoked its expression of
interest, stating that its board thought it was not feasible to attempt a merger
at that time.

         On July 21, 1999, SRNB received a detailed proposal from NVBancorp. The
board discussed the proposal at its meeting on July 27, 1999. At that meeting
Hoefer & Arnett Incorporated presented to the board a financial review of the
proposal, contrasting it to the Humboldt proposal which, at that time, had not
yet been revoked. The SRNB representatives reviewed such factors as the value of
the stock prices relative to each other and to a specified peer group, the
nature and inherent risk in the operations of the organizations, and the
similarities and differences in the culture and operating philosophies of the
organizations. Having completed its review the board determined that the
NVBancorp proposal was more advantageous to SRNB and its shareholders, and
unanimously directed the strategic planning committee to pursue the NVBancorp
proposal.

         In early August, 1999, a third financial institution contacted SRNB to
express interest in a business combination. After obtaining a confidentiality
agreement, the SRNB strategic planning committee met with representatives of
this institution. The institution submitted a written expression of interest to
SRNB on August 25, 1999 which was supplemented on September 8, 1999. However,
the SRNB board found that the terms of this expression of interest were less
favorable than those of NVBancorp and decided not to pursue further discussions.

         Commencing August 16, 1999, NVBancorp conducted its due diligence and
thoroughly reviewed the credit portfolio of SRNB. On September 1, 1999, SRNB and
NVBancorp and their respective counsel began negotiating the terms of the plan
of reorganization.

         On September 3, 1999, Humboldt again expressed interest in a merger
proposal. While the SRNB strategic planning committee stated its willingness to
hold a meeting with Humboldt representatives, a meeting was scheduled but never
held.

         At its board meeting on September 20, 1999, SRNB's legal counsel
presented to the board a detailed review of the terms of the proposed plan of
reorganization. Hoefer & Arnett Incorporated then presented a detailed analysis
of the financial terms of the transaction and delivered its draft opinion to the
effect that the proposed transaction was fair to SRNB and its shareholders from
a financial perspective. The board then established parameters for future
negotiations with NVBancorp and directed management to conduct a due diligence

                                      -34-
<PAGE>


review of NVBancorp. The SRNB board held special meetings on September 22 and
September 28, 1999 to review the due diligence findings and the status of the
negotiations. On October 1, 1999, the SRNB board approved the plan of
reorganization as being in the best interests of SRNB and its shareholders.

         On October 3, 1999 SRNB and NVBancorp executed the plan of
reorganization. Prior to the opening of the market on October 4, 1999, the
parties issued a joint press release publicly announcing the merger.

         Annex A to the joint proxy statement/prospectus contains a copy of the
plan of reorganization which is incorporated here by this reference.

         See "--Reasons for the Merger; Recommendations of the Boards of
Directors" and "--Opinion of SRNB's Financial Advisor" below.

REASONS FOR THE PLAN OF REORGANIZATION AND MERGER; RECOMMENDATIONS OF THE BOARDS
OF DIRECTORS

         NVBANCORP. The strategy of the board of directors of NVBancorp for
enhancing long-term value for NVBancorp shareholders recognizes that further
consolidation will occur in the banking and financial services industry in the
United States and that NVBancorp must be in a position to take advantage of this
change. Under this strategy, management of NVBancorp, at the direction of the
board of directors of NVBancorp, continually explores and evaluates acquisition
opportunities, such as the acquisition of SRNB as a continuing subsidiary of
NVBancorp, through the merger of SRNB into NVB Interim National Bank.

         In reaching the conclusion that the merger of SRNB into NVB Interim
National Bank is fair to and in the best interests of the shareholders of
NVBancorp, the board of directors of NVBancorp considered numerous factors,
including the following:

         (1)      The board of directors' familiarity with and review of SRNB's
                  business, results of operations, prospects and financial
                  condition and the willingness of the board of directors of
                  SRNB to consider a merger with NVB Interim National Bank;

         (2)      The opinion of Alex Sheshunoff & Co. Investment Banking, L.P.
                  that the terms of the merger are fair, from a financial point
                  of view, to NVBancorp shareholders;

         (3)      Economic conditions and prospects for the markets in which
                  NVBancorp and SRNB operate, and competitive pressures in the
                  financial services industry in general and the banking
                  industry in particular;

         (4)      The enhancement of NVBancorp's competitiveness and its ability
                  to serve its customers, depositors, creditors, other
                  constituents and the communities in which it operates as a
                  result of the merger;

         (5)      Information concerning the business, results of operations,
                  asset quality and financial condition of NVBancorp and SRNB on
                  a stand-alone and combined basis, and the future growth
                  prospects of NVBancorp and SRNB following the merger. In this
                  regard, the board of directors of NVBancorp gave consideration
                  to the results of the initial review conducted by NVBancorp's
                  management with respect to SRNB's business and operations,
                  including, in particular, its asset quality and certain
                  related conditions in the plan of reorganization. That review
                  included an assessment of the opportunities to achieve
                  increased market penetration in its existing market and to
                  expand into SRNB's market area in California;

         (6)      The cost savings and operational synergies which the
                  management of NVBancorp believes may be achieved as a result
                  of the merger through the elimination of duplicative efforts;

         (7)      An assessment that, in the current economic environment,
                  expansion through acquisition of another financial institution
                  is most economically advantageous to NVBancorp's shareholders
                  when compared to other alternatives such as de novo branch
                  openings or branch acquisitions;

         (8)      The geographic and business fit of NVBancorp and SRNB and the
                  complementary nature of their respective businesses including
                  the compatibility of their existing branch structures;

         (9)      Information with respect to historical trading ranges and
                  multiples for NVBancorp common stock and SRNB common stock,
                  and possible trading ranges and multiples for each on a
                  stand-alone basis and for the two companies on a combined
                  basis and the evaluation by the board of directors of
                  NVBancorp of the financial terms of the merger and their
                  effect on the shareholders of NVBancorp and the belief of the
                  NVBancorp board of directors that those terms are fair to
                  NVBancorp and its shareholders;

         (10)     The expectation that for federal income tax purposes the
                  merger will constitute a tax-free reorganization to NVBancorp
                  and its subsidiaries;

         (11)     The expectation that the merger will be accounted for under
                  the pooling of interests method of accounting;

         (12)     The terms and conditions of the plan of reorganization and the
                  related agreements;

         (13)     The likelihood of the merger being approved by the appropriate
                  regulatory authorities; and

         (14)     The structure of the merger and the resulting corporate
                  entities.

         The board of directors of NVBancorp did not assign any relative or
specific weights to the factors considered and individual directors may have
assigned different weights to the above factors.

         The board of directors of NVBancorp unanimously recommends that the
plan of reorganization, the related agreements, the transactions contemplated by
the plan of reorganization, including the merger and the issuance of NVBancorp
common stock in connection with the merger, and the proposal to classify the
NVBancorp board of directors, be approved by the NVBancorp shareholders.

         SRNB. The board of directors of SRNB believes that the merger is fair
to and in the best interests of the shareholders of SRNB. In reaching their
conclusion to approve the merger, the board of directors of SRNB considered
numerous factors, including the following:

         HISTORICAL AND RECENT MARKET PRICES OF SRNB SHARES COMPARED TO
NVBANCORP SHARES TO BE RECEIVED. The SRNB board of directors reviewed the
historical and recent trading prices for SRNB stock. The SRNB board of directors

                                      -36-
<PAGE>


considered as favorable the fact that SRNB shareholders would receive shares of
NVBancorp common stock that had a market value of $16.04 per share, representing
a premium of 19% over the closing sales price for SRNB shares of $13.50, on
October 1, 1999, the last full day of trading before the merger was publicly
announced. The SRNB board of directors also considered that after the trading
price of SRNB's common stock fell during 1998, it did not recover to the same
extent as many of the bank stocks in its peer group. The SRNB board of directors
also compared NVBancorp's stock price to book value ratio and the NVBancorp
price to earnings ratio not only with those of other potential acquirers, but
also to a specified peer group. Using the information as of June 30, 1999, this
comparison indicated that NVBancorp's common stock was trading at a substantial
discount as compared to the peer group. The price to last twelve month earnings
of the NVBancorp common stock was 10.0 times, while the median peer group
multiple was shown to be at 15.9 times. In the price to book value comparison,
NVBancorp was shown to be trading at 123.4% of book value while the peer group
median was at 221.3% of book value. The SRNB board of directors found favorable
the fact that NVBancorp's stock price to book value ratio was relatively low,
suggesting that, in this respect, the NVBancorp shares that SRNB shareholders
will receive in the merger may represent a greater value than SRNB shareholders
would receive in an identically priced or even a greater priced transaction with
a different acquirer. Lastly, using a fundamental valuation methodology known as
the discounted cash flow, the NVBancorp common stock was determined to be
trading at prices substantially below a high and low fundamental valuation range
of $16.09 to $19.57 per share. This further supports the suggestion that the
NVBancorp shares show considerable potential for appreciation.

         THE LIKELIHOOD THAT "POOLING OF INTERESTS" ACCOUNTING WILL NO LONGER BE
AVAILABLE FOLLOWING DECEMBER 31, 2000. The SRNB board of directors considered
the impact of the Financial Standards Accounting Board draft by which so-called
"pooling of interests" accounting will be eliminated by December 31, 2000. The
result of this accounting change will be that all mergers consummated after
December 31, 2000 will be accounted for as "purchase" transactions, resulting in
the amortization of goodwill in any merger where the purchase price exceeds the
asset value of the acquired company. The goodwill amortization will reduce
future reported income of the merged companies. Additionally, in bank mergers,
the goodwill in a purchase accounting transaction will not be included in the
calculation of regulatory capital requirements. Therefore, it is the belief of
the management and directors of SRNB, and it is the view of Hoefer & Arnett
Incorporated, that future bank mergers will result in lower premiums for the
seller. The SRNB board of directors believes that by combining with NVBancorp at
this time, it can take advantage of the "pooling of interests" accounting rules.
The SRNB board also believes that should the SRNB shareholders fail to approve
the NVBancorp proposal, it would be extremely unlikely that an alternative
transaction can be completed that would be eligible for "pooling of interests"
accounting treatment. Therefore, the NVBancorp transaction is most likely the
last opportunity that SRNB will have to engage in a "pooling of interests"
merger.

         SRNB'S BUSINESS, CONDITIONS AND GEOGRAPHIC PROSPECTS. The SRNB board of
directors considered information with respect to the financial condition,
results of operations and business risks of SRNB on both an historical and
prospective basis and current industry, economic and market conditions. Among
other things, the SRNB board considered the negative impact of continuing the
operations of SRNB exclusively in the confined geographic area in which SRNB
currently operates. SRNB's current marketplace has demonstrated slow growth
making internal growth of SRNB difficult to attain. The NVBancorp merger will
significantly expand the geographic base of the combined companies and will give
SRNB a greater market for the products and services of SRNB. The combination
with NVBancorp will also increase the legal lending limit of the combined
institutions giving greater flexibility to SRNB in meeting the credit needs of
its borrowers. The SRNB board of directors believes that this will greatly
enhance the long-term prospects for stock value.

         NVBANCORP'S BUSINESS, CONDITIONS AND PROSPECTS. The SRNB board of
directors considered information with respect to the financial condition,
financial performance, business operations, capital levels, asset quality, loan
portfolio breakdown and prospects of NVBancorp on both an historical and
prospective basis. The SRNB board of directors also considered information
regarding current industry, economic and market conditions in the financial
services industry. SRNB's financial advisers, Hoefer & Arnett Incorporated, made
presentations to and provided the SRNB board of directors with information
regarding NVBancorp's financial condition and prospects after conducting
business and financial due diligence. Officers of SRNB also made presentations
to the SRNB board of directors regarding NVBancorp's financial condition,
business and prospects after conducting business and financial due diligence.
These officers expressed their views that the corporate culture and operating
philosophies of NVBancorp were very compatible to those of SRNB. The SRNB board
viewed these observations as favorable for the future prospects of the combined
entity and the creation of further shareholder value. In evaluating NVBancorp's
prospects, the SRNB board of directors considered, among other things,
NVBancorp's financial performance, the geographic areas in which NVBancorp
conducts business compared to those in which SRNB conducts business, the state
of the economy in Northern California, the market conditions in the primary
areas in which NVBancorp conducts its business, and the effect those economies
may have on NVBancorp's performance. The SRNB board of directors also considered
and found favorable the fact that the NVBancorp's stock when combined with
SRNB's stock will have greater market capitalization and liquidity compared to
SRNB's current stock liquidity.

         OPINION OF HOEFER & ARNETT INCORPORATED. At its September 20 meeting,
the SRNB board of directors considered as favorable to its determination, Hoefer
& Arnett Incorporated's oral opinion delivered to the SRNB board of directors at
that meeting (which Hoefer & Arnett Incorporated subsequently confirmed in a
written legal opinion of that same date) that the consideration to be received
by SRNB shareholders in the merger was, as of that date, fair to SRNB's
shareholders, from a financial point of view.

         THE NEED OF SRNB TO OBTAIN 2/3 SHAREHOLDER VOTE FOR APPROVAL OF THE
PROPOSED MERGER. The articles of association of SRNB require that two-thirds
(2/3) equal to sixty-six and two-thirds percent (66 2/3%) of all of the
outstanding shares of SRNB be voted in favor of a merger. This means that for a
merger proposal to be successful it must meet the expectations of a broad
cross-section of the shareholders of SRNB. A merger proposal that does not meet
the expectations of all shareholder constituencies is likely to fail. For this
reason, in evaluating the options that were available to SRNB, the board of
directors believed that the NVBancorp transaction would yield the greatest
support of the SRNB shareholders. The board of directors believes that not only
do the transactions contemplated by the plan of reorganization, including the
merger, offer the best financial prospects for SRNB shareholders but it also
avoids the controversies and impact on the communities served by SRNB that have
in the past caused local shareholders to resist other merger overtures. The SRNB
board of directors believed that obtaining two-thirds approval of the
shareholders would be difficult, if not impossible, with any proposal that posed
problems within the communities served by SRNB.

         TERMS OF THE MERGER. The SRNB board of directors considered the terms,
conditions, covenants and representations contained in the plan of
reorganization and that the number and value of shares of NVBancorp common stock
to be issued in exchange for each outstanding share of SRNB common stock
represented the most favorable terms offered to SRNB in writing.

         THE TAX-FREE NATURE OF THE MERGER. The SRNB board of directors
considered and found favorable the fact that the merger is structured to be tax
free for federal income tax purposes. SRNB shareholders will recognize no gain
for federal income tax purposes in connection with the exchange of SRNB common
stock for NVBancorp common stock (except with respect to cash received in lieu
of shares of NVBancorp common stock).

         IMPACT ON COMMUNITIES, DEPOSITORS, CUSTOMERS AND EMPLOYEES. As is
required by its articles of association, the SRNB board of directors considered
the impact of the merger upon SRNB's communities, depositors, customers,
employees, the overall compatibility of SRNB's office and branch structure
compared to those of NVBancorp's. The ability of SRNB to continue as an on-going
bank under the NVBancorp holding company was viewed favorably for being least
disruptive of the communities served by SRNB, its depositors, customers and
employees. The SRNB board of directors believes that all of these constituencies
will be in favor of the merger.

         The SRNB board of directors did not assign any relative or specific
value to any of the factors.

         The board of directors of SRNB unanimously recommends that the plan of
reorganization, the related agreements and the transactions contemplated by
those agreements, including the merger of SRNB into NVB Interim National Bank,
be approved by the SRNB shareholders.

OPINION OF SRNB'S FINANCIAL ADVISOR

         GENERAL. SRNB engaged Hoefer & Arnett Incorporated on June 15, 1999, to
act as financial advisor to SRNB in connection with a merger. Hoefer & Arnett
agreed to assist SRNB in analyzing, structuring, negotiating, and effecting a
transaction with a potential acquiror, which after discussions with multiple
parties, was NVBancorp. As part of its engagement, Hoefer & Arnett agreed to
render to SRNB's board of directors an opinion with respect to the fairness from
a financial point of view of the consideration to be received by SRNB
shareholders in a potential sale of SRNB. Hoefer & Arnett is a nationally
recognized investment banking firm and, as part of its investment banking
activities, is regularly engaged in the valuation of businesses and their
securities in connection with merger transactions and other types of
acquisitions, negotiated underwritings, private placements and valuations for
corporate and other purposes. SRNB selected Hoefer & Arnett to render the
opinion on the basis of its experience and expertise and its reputation in the
banking and investment communities.

         At the request of SRNB's board of directors, representatives of Hoefer
& Arnett participated in the September 20, 1999 meeting at which SRNB's board of
directors considered the merger and in the October 1, 1999 meeting at which
SRNB's board of directors approved the plan of reorganization. At the September
20, 1999 meeting, Hoefer & Arnett delivered to SRNB's board of directors its
oral opinion, subsequently confirmed in writing as of October 1, 1999, that as
of that date, the consideration to be received by the holders of SRNB's common
stock in the merger was fair to the shareholders from a financial point of view.
Hoefer & Arnett has also delivered to SRNB's board of directors a written
opinion dated the date of this joint proxy statement/prospectus which is
substantially identical to the October 1, 1999 opinion.

         THE FULL TEXT OF HOEFER & ARNETT'S WRITTEN OPINION TO SRNB'S BOARD OF
DIRECTORS, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED, AND
LIMITATIONS OF THE REVIEW BY HOEFER & ARNETT IS ATTACHED AS ANNEX B TO THIS
JOINT PROXY STATEMENT/PROSPECTUS. YOU SHOULD READ THE HOEFER & ARNETT OPINION

HOEFER & ARNETT'S OPINION. IN FURNISHING THE OPINION, HOEFER & ARNETT DOES NOT
ADMIT THAT IT IS AN EXPERT WITH RESPECT TO THE REGISTRATION STATEMENT OF WHICH
THIS JOINT PROXY STATEMENT/PROSPECTUS IS A PART WITHIN THE MEANING OF THE TERM
"EXPERT" AS USED IN THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND

REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, NOR DOES IT ADMIT THAT
ITS OPINION CONSTITUTES A REPORT OR VALUATION WITHIN THE MEANING OF SECTION 11
OF THE SECURITIES ACT OF 1933, AS AMENDED. HOEFER & ARNETT'S OPINION IS DIRECTED
TO SRNB'S BOARD, COVERS ONLY THE FAIRNESS FROM A FINANCIAL POINT OF VIEW OF THE
CONSIDERATION TO BE RECEIVED BY SRNB SHAREHOLDERS AS OF THE DATE OF THE OPINION
AND DOES NOT CONSTITUTE A RECOMMENDATION TO SRNB SHAREHOLDERS AS TO HOW SRNB
SHAREHOLDERS SHOULD VOTE AT SRNB'S SPECIAL MEETING.

         In connection with its October 1, 1999 opinion, Hoefer & Arnett, among
other things:

         o    reviewed certain publicly available financial and other data with
              respect to SRNB and NVBancorp, including the consolidated
              financial statements for recent years and interim periods to June
              30, 1999, and certain other relevant financial and operating data
              relating to SRNB and NVBancorp made available to Hoefer & Arnett
              from published sources and from the internal records of SRNB and
              NVBancorp;

         o    reviewed the September 24, 1999 draft of the plan of
              reorganization;

         o    reviewed certain publicly available information concerning the
              trading of, and market for, SRNB common stock and NVBancorp common
              stock;

         o    compared certain financial data of SRNB and NVBancorp with those
              of certain other companies in the banking industry which Hoefer &
              Arnett deemed to be relevant;

         o    considered the financial terms, to the extent publicly available,
              of selected recent business combinations of companies in the
              banking industry which Hoefer & Arnett deemed to be comparable, in
              whole or in part, to the merger;

         o    conducted discussions with representatives of the senior
              management of SRNB and NVBancorp concerning their respective
              businesses and prospects;

         o    reviewed certain information, including financial forecasts and
              related assumptions furnished to Hoefer & Arnett by SRNB and
              NVBancorp, respectively; and

         o    performed such other analyses and examinations as Hoefer & Arnett
              deemed appropriate.

         In connection with Hoefer & Arnett's review, Hoefer & Arnett did not
assume any obligation independently to verify the information listed above and
relied on its accuracy and completeness in all material respects. With respect
to the financial forecasts for SRNB and NVBancorp provided to Hoefer & Arnett by
their respective managements, upon their advice and with SRNB's consent, Hoefer
& Arnett assumed for purposes of its opinion that the forecasts were reasonably
prepared on bases reflecting the best available estimates and judgments of their
respective managements at the time of preparation as to the future financial
performance of SRNB and NVBancorp and that they provided a reasonable basis upon
which Hoefer & Arnett could form its opinion. Hoefer & Arnett assumed that there
were no material changes in SRNB's or NVBancorp's assets, financial condition,
results of operations, business or prospects since the respective dates of their
last financial statements made available to Hoefer & Arnett. Hoefer & Arnett
relied on advice of counsel to SRNB as to all legal matters with respect to
SRNB, the merger and the plan of reorganization. Hoefer & Arnett assumed that
the merger will be completed in a manner that complies in all respects with the
applicable provisions of the Securities Act of 1933, as amended, the Securities
Exchange Act of 1934, as amended, and all other applicable federal and state
statutes, rules and regulations. In addition, Hoefer & Arnett did not assume
responsibility for reviewing any individual credit files, or making an
independent evaluation, appraisal or physical inspections of any of the assets
or liabilities (contingent or otherwise) of SRNB or NVBancorp, nor was Hoefer &

                                      -40-
<PAGE>


Arnett furnished with any appraisals. Hoefer & Arnett is not an expert in the
evaluation of loan portfolios for purposes of assessing the adequacy of the
allowances for losses with respect thereto and assumed, with SRNB's consent,
that the allowances for each of SRNB and NVBancorp were in the aggregate
adequate to cover the losses. SRNB informed Hoefer & Arnett, and Hoefer & Arnett
assumed, that the merger will be recorded as a pooling of interests under
generally accepted accounting principles. Finally, Hoefer & Arnett's opinion was
based on economic, monetary and market and other conditions as in effect on, and
the information made available to Hoefer & Arnett as of, the date of the
opinion.

         Set forth below is a brief summary of the information presented by
Hoefer & Arnett to SRNB's board of directors on September 20, 1999, in
connection with its opinion.

         DISCOUNTED DIVIDEND ANALYSIS. In performing the discounted dividend
analysis, Hoefer & Arnett used SRNB's management estimates of earnings per share
and dividend payments over a five-year period. The estimated earnings per share
in the year 2003 was multiplied by an estimated price to earnings multiple
ranging from 10.0x to 12.0x. This product was then added to the cumulative
estimated dividends for the prior five years and the sum of these two numbers
was discounted to the present using discount rates ranging from 12.5% to 15.0%.
This analysis indicated that the present value of SRNB's future stock price plus
dividends ranged form $10.53 to $13.80 per share. The $15.23 per share offer
from NVBancorp, based on a closing price for NVBancorp common stock of $10.50 on
September 15, 1999 exceeded the range of values implied by this analysis.

         COMPARABLE PUBLIC COMPANY ANALYSIS. Hoefer & Arnett analyzed the
financial performance and trading multiples of a comparison group of 15 publicly
traded California banks. SRNB's historical financial performance is below the
average performance of the selected California comparison group. The multiples
that were analyzed were price to tangible book value, price to latest twelve
months ("LTM") earnings and price to 1999 estimated earnings, excluding
institutions with price to LTM earnings greater than 18.0x. The low and mean
values of these multiples were then applied to SRNB's current values. This
analysis indicated a reference range for SRNB's current common stock price from
$7.46 to $9.88 with a mean value of $8.67, based on SRNB's 1999 estimated
earnings. Based on SRNB's tangible book value a reference range for SRNB's
current common stock price from $11.71 to $18.99 with a mean value of $15.35.
The mean of the two above methods indicates a reference price for SRNB's current
common stock of $12.01, as compared to NVBancorp's offer of $15.23 per share,
and SRNB's current price of $13.25 on September 15, 1999.

         ANALYSIS OF SELECTED MERGER TRANSACTIONS. Hoefer & Arnett reviewed the
consideration paid in selected categories of bank transactions for which the
relevant information was publicly available. Specifically, Hoefer & Arnett
reviewed selected bank transactions, involving mergers in California from
January 1, 1997 to September 15, 1999 with transaction values below $50 million
and return on average assets less than 1.0%. The multiples paid to SRNB in this
transaction are in line with multiples paid in transactions in each of the above
categories. For each transaction, Hoefer & Arnett analyzed data illustrating,
among other things, purchase price to tangible book value, one-month market
price premium paid and purchase price to LTM earnings.

         CONTRIBUTION ANALYSIS. Hoefer & Arnett analyzed the contribution of
each of SRNB and NVBancorp to, among other things, assets, loans, deposits, and
equity of the pro forma combined company for the period ending June 30, 1999,
and projected net income for the calendar year ending December 31, 1999 and
December 31, 2000. This analysis showed, among other things, that based on pro
forma combined balance sheets for SRNB and NVBancorp at June 30, 1999, SRNB
would have contributed approximately 40.2% of the assets, 34.8% of the gross
loans, 39.7% of the deposits, and 37.1% of the equity. The pro forma projected
income statement showed that SRNB would contribute approximately 21.8% of the
net income in 1999, and 26.8% of the net income in 2000. Based on an exchange
ratio of 1.450 of a share of NVBancorp common stock for each share of SRNB's
common stock, holders of SRNB's common stock would own approximately 36.4% of
the combined company based on common shares outstanding at June 30, 1999, in
line with its mean contribution.

         PRO FORMA EARNINGS DILUTION ANALYSIS. Using earnings estimates and
projected growth rates for SRNB and NVBancorp provided by their respective
managements, Hoefer & Arnett compared management's estimated earnings per share
("Estimated EPS") of SRNB's common stock on a stand-alone basis to the Estimated
EPS of the common stock for the pro forma combined company for the calendar year
ending December 31, 2000. Hoefer & Arnett noted that the merger would result in
an accretion of 35.1% to SRNB's Estimated EPS for the year ending December 31,
2000. These estimates were used for purposes of this analysis only and are not
necessarily indicative of expected results or plans of NVBancorp, SRNB or the
combined institution. Additionally, this analysis did not incorporate any
anticipated cost savings or revenue enhancements.

         PICKUP ANALYSIS. This analysis attempts to illustrate the increase in
per share values to SRNB shareholders as if the merger had been completed on
January 1, 1999. As shown below, the analysis shows an increase to SRNB
shareholders in dividends, fully-diluted tangible book value and earnings per
share. In performing the pickup analysis, Hoefer & Arnett applied the exchange
ratio of 1.450 of a share of NVBancorp common stock for each share of SRNB
common stock and applied it to the pro forma per share values for NVBancorp. The
results of this analysis were:

         The summary set forth above is not a complete description of the
presentation by Hoefer & Arnett to SRNB's board of directors or of the analyses
performed by Hoefer & Arnett. The preparation of a fairness opinion is not
necessarily susceptible to partial analysis or summary description. Hoefer &
Arnett believes that its analyses and the summary set forth above must be
considered as a whole and that selecting a portion of its analyses and factors,
without considering all analyses set forth in its presentation to SRNB's board
of directors. In addition, Hoefer & Arnett may have given various analyses more
or less weight than other analyses, and may have deemed various assumptions more
or less probable than other assumptions, so that the ranges of valuations
resulting from any particular analysis described above should not be taken to be
Hoefer & Arnett's view of the actual value of SRNB or the combined company. The
fact that any specific analysis has been referred to in the summary above is not
meant to indicate that the analysis was given greater weight than any other
analysis.

         In performing its analyses, Hoefer & Arnett made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters, many of which are beyond the control of SRNB or NVBancorp.
The analyses performed by Hoefer & Arnett are not necessarily indicative of
actual values or actual future results, which may be significantly more or less
favorable than suggested by the analyses. The analyses were prepared solely as
part of Hoefer & Arnett's analysis of the fairness of the consideration to be
received by SRNB shareholders in the merger and were provided to SRNB's board of
directors in connection with the delivery of Hoefer & Arnett's opinion. The
analyses are not appraisals and do not reflect the prices at which a company
might actually be sold or the prices at which any securities may trade at the
present time or any time in the future. The forecasts used by Hoefer & Arnett in
certain of its analyses are based on numerous variables and assumptions, which
are inherently unpredictable and must be considered not certain of occurrence as
projected. Accordingly, actual results could vary significantly from those
contemplated in the forecasts.

         As described above under "Proposal to Approve the Plan of
Reorganization and Merger ? Reasons for the Plan of Reorganization and Merger;
Recommendations of the Boards of Directors," Hoefer & Arnett's opinion and
presentation to SRNB's board of directors were among the many factors taken into
consideration by SRNB's board of directors in making its determination to

OPINION OF NVBANCORP'S FINANCIAL ADVISOR

         Alex Sheshunoff & Co. Investment Banking, L.P. was retained by
NVBancorp on September 15, 1999 to act as NVBancorp's financial advisor in
connection with the merger. Representatives of Sheshunoff participated in the
telephonic meeting of the NVBancorp board of directors held on September 23,
1999, at which the NVBancorp board of directors approved the plan of
reorganization. At that meeting, Sheshunoff rendered its preliminary oral
opinion to the effect that, as of the date thereof, the conversion ratio was
fair to NVBancorp from a financial point of view. Sheshunoff has reconfirmed its
oral opinion of September 23, 1999 by delivering a written opinion to the
NVBancorp board of directors, dated the date of this joint proxy
statement/prospectus to the effect that, as of the date thereof, the conversion
ratio was fair to the holders of NVBancorp common stock from a financial point
of view.

         THE FULL TEXT OF THE SHESHUNOFF OPINION, DATED THE DATE OF THIS JOINT
PROXY STATEMENT/PROSPECTUS, WHICH SETS FORTH THE ASSUMPTIONS MADE, PROCEDURES
FOLLOWED, MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS
ANNEX C TO THIS JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HERE BY
THIS REFERENCE. THE SHESHUNOFF OPINION WAS PROVIDED TO THE NVBANCORP BOARD OF
DIRECTORS FOR ITS INFORMATION, IS DIRECTED ONLY TO THE FAIRNESS OF THE
CONVERSION RATIO FROM A FINANCIAL POINT OF VIEW AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY NVBANCORP SHAREHOLDER AS TO HOW THE SHAREHOLDER SHOULD
VOTE AT THE NVBANCORP MEETING WITH RESPECT TO THE MERGER OR ANY OTHER RELATED
MATTER. THE DESCRIPTION OF THE SHESHUNOFF OPINION SET FORTH ABOVE IS QUALIFIED
IN ITS ENTIRETY BY REFERENCE TO ANNEX C. NVBANCORP SHAREHOLDERS ARE URGED TO
READ THE SHESHUNOFF OPINION IN ITS entirety.

         In connection with rendering the Sheshunoff opinion, Sheshunoff, among
other things: (i) reviewed the plan of reorganization; (ii) reviewed annual
reports to shareholders and annual reports on Form 10-K of NVBancorp and SRNB,
as well as certain quarterly reports on Form 10-Q of NVBancorp and SRNB; (iii)

                                      -44-
<PAGE>


reviewed certain internal financial analyses and forecasts, including forecasts
of certain cost savings expected by NVBancorp to be achieved as a result of the
merger ("Synergies"); (iv) discussed with members of the senior management of
NVBancorp the past and current business operations, regulatory relationships,
financial conditions and future prospects of NVBancorp; (v) reviewed with
members of senior management of NVBancorp the results of NVBancorp's due
diligence examination of SRNB and the strategic benefits expected to be derived
from the merger; (vi) reviewed the reported price and trading activity for
NVBancorp common stock and SRNB common stock; (vii) compared certain financial
and stock market information for NVBancorp and SRNB with similar information for
certain other companies, the securities of which are publicly traded; (viii)
reviewed the financial terms of certain recent business combinations in the
commercial banking industry; and (ix) performed other studies and analyses as it
considered appropriate. NVBancorp did not request or retain Sheshunoff to assist
in NVBancorp's due diligence review of SRNB. Sheshunoff did not independently
review any of NVBancorp's or SRNB's assets or liabilities and did not visit
either NVBancorp or SRNB.

         As set forth in the Sheshunoff opinion, Sheshunoff relied upon the
accuracy and completeness of all of the financial and other information reviewed
by it and assumed the accuracy and completeness for purposes of the Sheshunoff
opinion. In that regard, Sheshunoff assumed, with NVBancorp's consent, that the
financial forecasts, including, without limitation, the Synergies and
projections regarding under-performing and non-performing assets and net
charge-offs had been reasonably prepared on a basis reflecting the best then
available judgments and estimates of NVBancorp and SRNB and that these forecasts
will be realized in the amounts and at the times contemplated. Sheshunoff makes
no representations or warranty that the financial forecasts and projections
prepared by NVBancorp will be realized in the amounts and at the times
forecasted and projected. The fairness of the conversion ratio is based upon
recognizing the financial forecasts and projections without negative deviations
from the forecasted and projected results. The value of the combined company
following the merger is significantly affected by the cost savings estimate and
the projections regarding the under-performing and non-performing assets and net
charge-offs.

         Sheshunoff is not an expert in the evaluation of loan and lease
portfolios for purposes of assessing the adequacy of the allowance for losses
with respect thereto and assumed, with NVBancorp's consent, that the allowances
for each of NVBancorp and SRNB are in the aggregate adequate to cover all
losses. In addition, Sheshunoff did not review individual credit files nor did
it make an independent evaluation or appraisal of the assets and liabilities of
NVBancorp or SRNB or any of their respective subsidiaries and had not been
furnished with any evaluation or appraisal. Sheshunoff also assumed, with
NVBancorp's consent, that the merger will be accounted for as a
pooling-of-interests under generally accepted accounting principles and that
obtaining any necessary regulatory approvals and third party consents for the
merger or otherwise will not have an adverse effect on NVBancorp, SRNB or the
combined company resulting from the merger.

         The advisory services and the Sheshunoff opinion provided by Sheshunoff
were for the information and assistance of the NVBancorp board of directors in
connection with its consideration of the merger and do not constitute a
recommendation as to how any NVBancorp shareholder should vote with respect to
the merger.

         The following is a summary of the material financial analyses
considered by Sheshunoff in arriving at its opinion and is not a complete
description of the analyses performed by Sheshunoff.

         SUMMARY OF TERMS OF PROPOSED TRANSACTION. Sheshunoff reviewed the terms
of the proposed merger, including the expected method of accounting, the
conversion ratio, the share price of NVBancorp as of September 22, 1999, the
resulting indicated value per share of SRNB common stock (the "Indicated Value")
of the merger and the resulting indicated aggregate consideration (the

                                      -45-
<PAGE>


"Indicated Aggregate Consideration") to be paid in the merger. The proposed
method of accounting for the merger was a pooling-of-interests in a tax-free
exchange. The Indicated Value was $15.38 per share of SRNB common stock,
determined by multiplying the conversion ratio by the closing price on the
Nasdaq National Market of NVBancorp common stock on September 22, 1999. The
Indicated Aggregate Consideration to be paid in the merger was $24.112 million
based on 1.568 million fully diluted shares outstanding (utilizing the treasury
stock method at the Indicated Value).

         The analysis noted that the Indicated Value constituted: (i) a multiple
of 20.7x SRNB's annualized earnings for the six months ended June 30, 1999, (ii)
a multiple of 20.1x the Institutional Broker Estimate System ("IBES") median
estimates of SRNB's 1999 earnings, and (iii) a multiple of 17.1x the IBES median
estimates of SRNB's 2000 earnings. The Indicated Value also reflected a multiple
of 1.29x SRNB's stated book value and a multiple of 1.74x SRNB's tangible book
value based on a June 30, 1999 book value of $18.626 million and tangible book
value of $13.887 million. The Indicated Aggregate Value represented a deposit
premium of 14.1%. In performing these analyses, Sheshunoff used estimates based
upon the most recent median earnings estimates published by the IBES as of
September 22, 1999. IBES is a data service that monitors and publishes
compilations of earnings estimates by selected research analysts regarding
companies of interest to institutional investors.

         COMPARISON OF SELECTED COMPARABLE COMPANIES - SRNB. Based on publicly
available information and IBES earnings estimates, Sheshunoff reviewed and
compared actual and estimated selected financial, operating and stock market
information and financial ratios of SRNB and a group of 13 additional banking
organizations which Sheshunoff deemed to be relevant. The group consisted of the
Bank of Hemet, BYL Bancorp, California Independent Bancorp, Coast Bancorp,
Community West Bancshares, Desert Community Bank, Foothill Independent Bancorp,
National Mercantile Bancorp, North County Bancorp, NVBancorp Bancorp,
Professional Bancorp, Inc., Redwood Empire Bancorp, and Wilshire State Bank (the
"SRNB Selected Banks"). This comparison showed, among other things, that for the
three months ended June 30, 1999 (i) SRNB's ratio of non-interest expense to
average assets was 3.9% compared to a median of 5.2% for the SRNB Selected
Banks, (ii) SRNB's ratio of non-interest income to average assets was 0.84%
compared to a median of 1.38% for the SRNB Selected Banks, (iii) SRNB's net
interest margin was 4.49% compared to a median of 5.92% for the SRNB Selected
Banks, (iv) SRNB's efficiency ratio (defined as non-interest expenses divided by
the sum of noninterest income and net interest income before provision for loan
losses) was 76.1% compared to a median of 68.6% for the SRNB Selected Banks, (v)
SRNB's return on average assets was 0.52% compared to a median of 1.10% for the
SRNB Selected Banks, and (vi) SRNB's return on average common equity was 5.52%
compared to a median of 12.16% for the SRNB Selected Banks. This comparison also
indicated that as of September 22, 1999, (A) the ratio of SRNB's market price to
estimated earnings for the twelve month period ending December 31, 2000 was
16.8x compared to a median of 10.6x for the SRNB Selected Banks, (B) the ratio
of SRNB's market price to stated book value per share at June 30, 1999 was 1.08x
compared to a median of 1.40x for the SRNB Selected Banks, (C) the ratio of
SRNB's market price to tangible book value per share at June 30, 1999 was 1.45x
compared to a median of 1.71x for the SRNB Selected Banks, (D) SRNB's dividend
yield was 0.0% compared to a median of 1.2% for the SRNB Selected Banks, and
(E), SRNB had a market capitalization of $19.8 million.

         COMPARISON OF SELECTED COMPARABLE COMPANIES - NVBANCORP. Based on
publicly available information and IBES earnings estimates, Sheshunoff reviewed
and compared actual and estimated selected financial, operating and stock market
information and financial ratios of NVBancorp and a group of 13 additional
banking organizations which Sheshunoff deemed to be relevant. The group
consisted of the Bank of Hemet, BYL Bancorp, California Independent Bancorp,
Coast Bancorp, Community West Bancshares, Desert Community Bank, Foothill
Independent Bancorp, National Mercantile Bancorp, North County Bancorp, SRNB,
Professional Bancorp, Inc., Redwood Empire Bancorp, and Wilshire State Bank (the
"NVBancorp Selected Banks"). This comparison showed, among other things, that

                                      -46-
<PAGE>


for the three months ended June 30, 1999 (i) NVBancorp's ratio of non-interest
expense to average assets was 3.3% compared to a median of 5.2% for the
NVBancorp Selected Banks, (ii) NVBancorp's ratio of non-interest income to
average assets was 1.11% compared to a median of 1.38% for the NVBancorp
Selected Banks, (iii) NVBancorp's net interest margin was 5.14% compared to a
median of 5.92% for the NVBancorp Selected Banks, (iv) NVBancorp's efficiency
ratio (defined as non-interest expenses divided by the sum of non-interest
income and net interest income before provision for loan losses) was 56.0%
compared to a median of 68.6% for the NVBancorp Selected Banks, (v) NVBancorp's
return on average assets was 1.27% compared to a median of 1.10% for the
NVBancorp Selected Banks, and (vi) NVBancorp's return on average common equity
was 12.11% compared to a median of 12.16% for the NVBancorp Selected Banks. This
comparison also indicated that as of September 22, 1999, the ratio of
NVBancorp's market price to estimated earnings for the twelve month period
ending December 31, 2000 was 8.9x compared to a median of 10.6x for the
NVBancorp Selected Banks, the ratio of NVBancorp's market price to stated book
value per share at June 30, 1999 was 1.23x compared to a median of 1.40x for the
NVBancorp Selected Banks, the ratio of NVBancorp's market price to tangible book
value per share at June 30, 1999 was 1.23x compared to a median of 1.71x for the
NVBancorp Selected Banks, (D) NVBancorp's dividend yield was 3.6% compared to a
median of 1.2% for the NVBancorp Selected Banks, and (E), NVBancorp had a market
capitalization of $38.9 million.

         SELECTED TRANSACTION ANALYSIS. Sheshunoff reviewed certain information
relating to six announced or completed bank mergers since January, 1998 in which
the seller reported a non-performing asset ratio above 1% (the "Selected Bank
Mergers") and which it deemed to be relevant. The Selected Bank Mergers were
(identified by acquiror/acquiree): Belvedere Capital Partners/Bank of Orange
County, First Coastal Bancshares/American Independent Bank NA, OffRoad Capital
Corporation/Sequoia National Bank, Summitt Bank Corporation/California Security
Bank, and Washington Mutual, Inc./Industrial Bank.

         The analysis indicated that the NVBancorp/SRNB Merger had: (i) a price
to annualized six months net income multiple of 20.7x as compared with a median
price to last twelve months net income of 29.8x for the Selected Bank Mergers,
(ii) a price to book multiple of 1.29x as compared with a median price to book
multiple of 2.00x for the Selected Bank Mergers, (iii) a price to tangible book
multiple of 1.74x as compared with a median price to tangible book multiple of
2.01x for the Selected Bank Mergers, (iv) a price to assets ratio of 12.1% as
compared with a median price to assets ratio of 16.2% for the Selected Bank
Mergers, and (v) a price to deposits ratio of 14.1% as compared with a median
price to deposits ratio of 19.2% for the Selected Bank Mergers.

         PRO FORMA ANALYSIS. Based on projections provided by NVBancorp,
Sheshunoff analyzed the pro forma per share impact of the merger on a variety of
measures including, among other things, earnings per share, cash earnings per
share, tangible book value per share and various profitability measures. Share
prices for NVBancorp common stock and SRNB common stock were based upon closing
prices on September 22, 1999. The analysis was based on the assumption that the
combined companies would realize projected cost savings assumptions in the
amounts and within time periods assumed by Sheshunoff. FOR THE PURPOSE OF THIS
ANALYSIS, SHESHUNOFF UTILIZED THE SAME COST SAVINGS PROVIDED NVBANCORP
MANAGEMENT, BUT ASSUMED THAT THOSE SAVINGS WOULD BE ACHIEVED LESS QUICKLY THAN
NVBANCORP MANAGEMENT PROJECTED. The analysis assumed net pre-tax cost savings of
$2.2 million which represented 29.2% of SRNB's projected 1999 non-interest
expense base of $7.7 million. It was assumed that NVBancorp would realize 25% of
the cost savings in 2000, 50% in 2001, 75% in 2002 and 100% of the cost savings
in 2003. The analysis also assumed a $900 thousand after-tax restructuring
charge to be taken by NVBancorp by the end of 2000. The earnings dilution
experienced in 2000 includes the impact of $900 thousand in merger related
transaction costs that are one-time expenses.

                                      -47-
<PAGE>


         The analysis performed indicated that on a per share basis, the
transaction would be dilutive to NVBancorp's estimated earnings per share by 13%
in 2000 and accretive to NVBancorp's estimated earnings per share by 8% in 2001
and 16% in 2002. The analysis also indicated that the transaction would be
dilutive to NVBancorp's estimated cash earnings per share by 9% in 2000 and
would be accretive to NVBancorp's estimated cash earnings per share by 12% in
2001 and 19% in 2002.

         DISCOUNTED DIVIDEND STREAM ANALYSIS. Using a discounted dividend stream
analysis, Sheshunoff estimated the present value of the future streams of
after-tax cash flows that SRNB could produce and distribute to shareholders. The
analysis assumed net pre-tax cost savings of $2.2 million which represented
29.2% of SRNB's projected 1999 non-interest expense base of $7.7 million. It was
assumed that NVBancorp would realize 25% of the cost savings in 2000, 50% in
2001, 75% in 2002 and 100% of the cost savings in 2003. The analysis also
assumed a $900 thousand after-tax restructuring charge to be taken by NVBancorp
by the end of 2000. Sheshunoff assumed that SRNB would generate 6% asset and
earnings growth and that SRNB's tangible common equity to tangible asset ratio
would be maintained at an 8% level. Sheshunoff estimated the terminal values for
the SRNB common stock at 10.0x and 15.0x SRNB's 2004 estimated operating income
(defined as net income before intangible amortization). The dividendable cash
flow streams and terminal values were then discounted to present values using
discount rates (ranging from 14% to 16%) chosen to reflect different assumptions
regarding required rates of return of holders or prospective buyers of SRNB's
common stock. This discounted dividend stream analysis indicated a reference
range of $11.87 to $18.02 per share for SRNB's common stock.

         The summary set forth above describes the material analyses that
Sheshunoff performed in rendering the Sheshunoff's opinion and is not a complete
description of those analyses. The preparation of a fairness opinion is a
complex process. Sheshunoff believes that its analyses must be considered as a
whole and that selecting portions of its analyses without considering all
factors and analyses creates an incomplete view of the analyses and processes
underlying its opinion. In its analyses, Sheshunoff relied upon numerous
assumptions made by NVBancorp and Six Rivers regarding their future operation as
independent and combined companies with respect to industry performance, general
business and economic conditions, and other matters, many of which are beyond
the control of NVBancorp or SRNB. Analyses based upon forecasts of future
results are not necessarily indicative of actual values, which may be
significantly more or less favorable than suggested by the analyses. No company
or transaction used as a comparison in the analyses is identical to NVBancorp or
SRNB or to the merger. Additionally, estimates of the value of businesses are
not appraisals or necessarily reflective of the prices at which businesses
actually may be sold. Because estimates are inherently subject to uncertainty,
none of the NVBancorp board of directors, Sheshunoff, nor any other person
assumes responsibility for the accuracy of estimates. Sheshunoff prepared the
analyses solely for purposes of rendering the Sheshunoff opinion regarding the
fairness of the conversion ratio to NVBancorp from a financial point of view.
The analyses are not appraisals or necessarily and may not reflect the prices at
which SRNB common stock may actually be sold.

         For its services as financial advisor to NVBancorp, NVBancorp has
agreed to pay Sheshunoff a cash fee of $7,500 which was paid upon execution by
NVBancorp of an engagement letter with Sheshunoff on September 15, 1999, and an
additional cash fee of $7,500 which was paid upon delivery of Shehunoff's
opinion. Sheshunoff was engaged solely for the purposes of determining whether
the conversion ratio is fair from a financial point of view to the common
shareholders of NVBancorp. NVBancorp also agreed to indemnify and hold harmless
Sheshunoff and its officers and employees against certain liabilities in
connection with its services under the engagement letter, except for liabilities
resulting from the negligence of Sheshunoff.

         The full text of Alex Sheshunoff & Co. Investment Banking, L.P.'s
written opinion dated the date of this joint proxy statement/prospectus is
attached as Annex C and is incorporated here by this reference.

         NVBancorp shareholders are urged to read the opinion in its entirety
for a description of the procedures followed, assumptions made, matters
considered, and qualifications and limitations on the review undertaken by Alex
Sheshunoff & Co. Investment Banking, L.P.

EFFECTIVE DATE AND TIME OF THE MERGER

         The plan of reorganization provides that the merger will be effective
on the date and at the time selected by the parties after the merger has been
certified by the Office of the Comptroller of the Currency, an executed copy of
the bank plan of reorganization and merger has been filed with and accepted by
the Office of the Comptroller of the Currency, all government approvals have
been received and satisfied and all other conditions to the merger have been
satisfied. The date and time on which the merger is effective as specified in
the plan of reorganization is referred to in this document as the effective date
and effective time, respectively. Although the parties have not adopted any
formal timetable, it is presently anticipated that the merger will be
consummated during March 2000, assuming all of the conditions set forth in the
plan of reorganization are satisfied or waived.

PURCHASE PRICE AND POTENTIAL ADJUSTMENTS

         Each share of SRNB common stock issued and outstanding prior to the
effective time of the merger, other than shares as to which dissenters' rights
have been perfected, will be converted into the right to receive a number of
NVBancorp shares of common stock, plus cash in lieu of fractional shares,
according to a conversion ratio based on the average of the daily average of bid
and ask prices for NVBancorp shares on the Nasdaq National Market for the twenty
(20) consecutive trading days ending at the end of the third trading day
immediately preceding the effective time of the merger, rounded to four decimal
places (whether or not trades occurred on those days).

         If the average closing price is not less than $10.00 and is not more
than $12.06, the conversion ratio will be 1.450; if the average closing price is
not less than $12.07 and is not more than $12.50, the conversion ratio will be
determined by dividing $17.50 by the average closing price; if the average
closing price is more than $12.50 but is not more than $15.00, the conversion
ratio will be 1.400.

         If the average closing price is less than $10.00, then the board of
directors of SRNB may elect to terminate the plan of reorganization; provided,
however, that if SRNB does not give NVBancorp timely notice of termination, then
the conversion ratio will be 1.450 and the merger closing will go forward. See
"The Merger-Termination of the Plan of Reorganization" on page 61.

         If the average closing price is greater than $15.00, then the
conversion ratio will be determined in accordance with a formula calculated as
follows: the conversion ratio will equal $21.00 PLUS 0.56 times the number equal
to the average closing price MINUS $15.00, with the sum DIVIDED by the average
closing price.

                                      -49-

         The following table summarizes the conversion ratio variables set forth
above:

         average closing price      conversion ratio
         ---------------------      ----------------
         under $10.00               1.450 (unless merger terminated)
         $10.00 to $12.06           1.450
         $12.07 to $12.50           $17.50 divided by the average closing price
         $12.51 to $15.00           1.400
         over $15.00                according to formula

         The obligation of NVBancorp to consummate the transactions contemplated
by the plan of reorganization, including the merger, is subject to the condition
that, among other matters, as of the effective time of the merger SRNB will have
total shareholders' equity and leverage, tier 1 and total risk-based capital
ratios, respectively, in amounts required to comply with the "well capitalized"
category of applicable federal banking regulations and total reserves for losses
on outstanding loans in compliance with the SRNB loan loss policy and procedures
and at a level which, in the reasonable determination of NVBancorp, are adequate
for regulatory purposes and for purposes of generally accepted accounting
principles. See "Proposal to Approve the Plan of Reorganization and
Merger--Conduct of Business Pending the Merger" on page 53 and "Conditions to
the Completion of the Merger" on page 58. If the shareholders' equity of SRNB
as of the third business day prior to the closing date is less than $19,000,000,
then the conversion ratio will be re-calculated by NVBancorp and SRNB by
reducing the conversion ratio by 0.010 for each whole $100,000 amount of
shortfall then existing in the shareholders' equity of SRNB. For instance, if
the average closing price is $12.50, and the shareholders' equity of SRNB is
$18,899,000, then the conversion ratio will be 1.390. For this purpose,
shareholders' equity of SRNB is the sum of common stock par value, plus
additional paid in capital, plus retained earnings (or accumulated deficit), as
reflected on the books of SRNB. As of September 30, 1999, shareholders' equity
of SRNB was $19,641,000.

         No fractional shares of NVBancorp shares of common stock will be issued
to holders of SRNB common stock. Instead, each holder entitled to a fraction of
a share will receive, at the time of surrender of the certificate or
certificates representing the holder's shares, an amount in cash equal to the
market value per share of the fractional shares. The market price will be based
on the closing price of NVBancorp shares on the Nasdaq National Market on the
trading day immediately preceding the effective time of the merger. No SRNB
shareholder will be entitled to dividends, voting rights, interest on the value
of, or any other rights in respect of a fractional share of NVBancorp common
stock.

CONVERSION OF SHARES OF SRNB COMMON STOCK

         At the effective time, by virtue of the merger and without any action
on the part of the holders of SRNB common stock, each issued and outstanding
share of SRNB common stock (other than dissenting and fractional shares) will be
converted into the right to receive the per share consideration of NVBancorp
common stock as discussed above. See "--Purchase Price and Potential
Adjustments" on page 49. All shares of SRNB common stock will no longer be
outstanding and will automatically be canceled and retired and will cease to
exist, and each certificate previously representing any SRNB shares will
thereafter represent the shares of NVBancorp common stock into which such shares
of SRNB common stock have been converted. Certificates previously representing
shares of SRNB common stock will be exchanged for certificates representing
whole shares of NVBancorp common stock issued in consideration therefor upon the
surrender of those certificates. Cash will be paid in lieu of any fractional
share of NVBancorp common stock. See "--Exchange of SRNB Stock Certificates;
Fractional Interests" on page 51. From and after the effective date, the
holders of certificates formerly representing shares of SRNB common stock will
cease to have any rights with respect to those shares.

                                      -50-

EXCHANGE OF SRNB STOCK CERTIFICATES; FRACTIONAL INTERESTS

         Prior to the effective date, NVBancorp has agreed to appoint Chase
Mellon Shareholder Services, LLC, or its successor as exchange agent (the
"Exchange Agent") for the purpose of exchanging certificates representing shares
of NVBancorp common stock, and at and after the effective date, NVBancorp will
issue and deliver to the Exchange Agent certificates representing the shares of
NVBancorp common stock to be delivered to holders of shares of SRNB common
stock. As soon as practicable after the effective date, each holder of shares of
SRNB common stock, upon surrender to the exchange agent of one or more
certificates for the shares of SRNB common stock for cancellation, will be
entitled to receive a certificate representing the number of shares of NVBancorp
common stock into which the number of shares of SRNB common stock will have been
converted and a payment in cash with respect to fractional shares, if any.

         No dividends or other distributions of any kind which are declared
payable to shareholders of record of the shares of NVBancorp common stock after
the effective date will be paid to persons entitled to receive the certificates
for shares of NVBancorp common stock until those persons surrender their
certificates representing shares of SRNB common stock. Upon surrender of
certificates representing shares of SRNB common stock, the holder thereof will
be paid, without interest, any dividends or other distributions with respect to
the shares of NVBancorp common stock as to which the record date and payment
date occurred on or after the effective date and on or before the date of
surrender.

         If any certificate for shares of NVBancorp common stock is to be issued
in a name other than that in which the certificate for shares of SRNB common
stock surrendered in exchange therefor is registered, it will be a condition of
the exchange that the person requesting the exchange will pay to the Exchange
Agent any transfer costs or other expenses (except taxes) required by reason of
the issuance of certificates for the shares of NVBancorp common stock in a name
other than the registered holder of the certificate surrendered.

         All dividends or distributions, and any cash to be paid in lieu of
fractional shares, if held by the Exchange Agent for payment or delivery to the
holders of unsurrendered certificates representing shares of SRNB common stock
and unclaimed at the end of one year from the effective date, will (together
with any interest earned thereon) at that time be paid or redelivered by the
Exchange Agent to NVBancorp, and after that time any holder of a certificate
representing shares of SRNB common stock who has not surrendered the certificate
to the Exchange Agent will, subject to applicable law, look as a general
creditor only to NVBancorp for payment or delivery of the shares of NVBancorp
common stock and dividends or distributions or cash, as the case may be.

         No fractional shares of NVBancorp common stock will be issued to
holders of shares of SRNB common stock. In lieu thereof, each holder entitled to
a fraction of a share of NVBancorp common stock will receive, at the time of
surrender of the certificate or certificates representing the holder's shares of
SRNB common stock, an amount in cash equal to the market value per share of
NVBancorp common stock multiplied by the fraction of a share of NVBancorp common
stock to which the holder otherwise would be entitled. The market value of
NVBancorp common stock is calculated using the closing price of the NVBancorp
common stock on the Nasdaq National Market on the trading day immediately
preceding the effective time. No holder will be entitled to dividends, voting
rights, interest on the value of, or any other rights in respect of, a
fractional share.

<PAGE>

TREATMENT OF STOCK OPTIONS

         At the effective time, the obligations under the SRNB stock option plan
will be assumed by NVBancorp. At the effective time, options to purchase shares
of SRNB common stock issued under SRNB's stock option plan that are outstanding
will be converted, without any action on the part of the holders thereof, into
substitute options to acquire the number of shares of NVBancorp common stock the
option holder would have received in the merger if he or she had exercised all
of his or her options immediately prior to the effective date. The option
exercise price will be adjusted to equal the exercise price per share for the
options immediately prior to the merger divided by the conversion ratio, as the
conversion ratio may be adjusted. Except as noted above, each SRNB stock option
will otherwise continue on terms and conditions that are consistent with those
that were applicable on the effective date.

INTERESTS OF SRNB OFFICERS AND DIRECTORS IN THE MERGER

         SRNB directors and executive officers have interests in the merger in
addition to their interests as SRNB shareholders. The SRNB board of directors
was aware of these interests and considered them, among other matters, in
approving the plan of reorganization. See "Introduction -Share Ownership of
Management" on page 25.

         As of the record date, the directors and executive officers of SRNB
owned an aggregate of _____________ shares of SRNB common stock (including
_______ shares subject to options exercisable currently or within 60 days of the
record date) which, if owned by them at the effective date of the merger, will
be converted into shares of NVBancorp common stock with an approximate aggregate
market value of $___________ (based on the $________ per share closing price of
NVBancorp common stock on the Nasdaq National Market on the trading day
immediately preceding the date the registration statement was filed. Under the
plan of reorganization, NVBancorp has agreed to appoint two current directors of
SRNB to the NVBancorp board of directors who will be entitled to receive the
directors' fees and benefits which NVBancorp extends to its directors.
Additionally, all of the current SRNB directors will continue to serve on the
board of directors of SRNB and two of NVBancorp's current directors will become
members of the board of directors of SRNB and become entitled to receive the
directors' fees and benefits which SRNB extends to its directors.

         Mr. Martinez, President and Chief Executive Officer of SRNB, Shelton
Francis, Executive Vice President and Chief Credit Officer of SRNB, Margie Plum,
Executive Vice President and Secretary of SRNB (the "SRNB executive officers" )
are parties to transition agreements that provide for severance benefits upon
the occurrence of a change of control such as the merger. These agreements
provide that, for a period of two years following a change of control, any SRNB
executive officer has the sole discretion to terminate employment and receive a
lump sum payment or periodic monthly payments equal to 35 months of then current
base salary, plus bonuses paid for the prior two years. Under these provisions
Mr. Martinez, Mr. Francis, and Mrs. Plum would be entitled to $400,000,
$306,000, and $226,000, respectively. Nine other SRNB officers also have
transition agreements. These agreements provide that, for two years following a
change of control, the officer has the sole discretion to terminate employment
and receive a lump sum payment or periodic monthly payments equal to 12 months
of then current base salary. If all nine officers were to elect payment, the
total would be $552,000.

         The SRNB executive officers also have three-year employment agreements
dated April 1, 1999 with SRNB. The agreements provide severance of 18 months
base salary or the remaining base salary due under the contract, whichever is
less, in the event of termination without cause.

                                      -52-
<PAGE>


         Mr. Martinez and Mrs. Plum are each covered by a supplemental executive
retirement agreement under which benefits vest 100% in the case of a change of
control. Due to the merger, Mr. Martinez and Mrs. Plum are entitled to,
respectively, an annual retirement benefit of $215,136 and $78,115 for a period
of 15 years. Payment begins at age 65 or at termination of employment, whichever
is later.

         In addition, the plan of reorganization provides SRNB directors and
officers with certain rights to indemnification by NVBancorp. See "Comparison Of
Shareholder Rights--Indemnification of Directors and Executive Officers" on page
83.

              substantially equivalent to cash dividends paid in the two years
              prior to the date of the plan of reorganization.

         In addition, SRNB has agreed that it will:

         o    take all necessary action to terminate the SRNB stock option plan
              at the effective time of the merger and the exercise or surrender
              (in exchange for substitute options) of SRNB options outstanding

              sharing, pension, retirement, severance, incentive or other
              employee benefit program or arrangement other than compensation

              prior written consent, and except for payments to officers and
              employees of SRNB of regular salary increases, consistent with
              past practices in connection with regular salary reviews or
              bonuses consistent with past practices, as disclosed to NVBancorp;

         o    not cause, allow or suffer its officers or agents to commit to any
              loan or renewal which does not comply in all material respects
              with its credit policies in effect and as disclosed to NVBancorp
              prior to the date of the plan of reorganization, provided,
              however, that all new stand-alone extensions of credit over
              $200,000, except for conforming FHLMC and FNMA loans, will be
              subject to NVBancorp's prior written consent. The prior written

                                      -54-
<PAGE>

              consent of NVBancorp will be deemed waived for any new stand-alone
              extension of credit that is below $200,000 and where the new
              stand-alone extension of credit is either in compliance with SRNB
              credit policy and the approving officer has the requisite lending
              authority or has (have) been approved by the SRNB loan committee
              or equivalent committee of the SRNB board of directors performing
              that function;

         o    notify NVBancorp promptly in writing upon the occurrence of: (1)
              the classification of any loan as "Non-Accrual," "Watch," "Other
              Assets Specially Mentioned," "Substandard," "Doubtful" or "Loss";
              or (2) the filing or commencement of any legal action or other
              proceeding or investigation against SRNB; and will provide to
              NVBancorp on request reports on certain loans as described in the
              plan of reorganization; and

         o    subject to certain exceptions, incur or commit to any capital
              expenditures for more than $50,000 in the aggregate.

         Additionally, NVBancorp has agreed that it will:

         o    amend the articles of association and bylaws of NVB Interim
              National Bank, subject to obtaining requisite shareholder and
              governmental approvals, to change the name of the resulting bank
              to SRNB National Bank and to provide to a board of directors
              consisting of five to eleven members with the exact number of
              directors set at eight or another number agreed by the parties;

         o    take action to offer substitute stock options, exercisable for an
              equivalent number of shares of NVBancorp common stock, to all
              holders of SRNB stock options;

         o    take all necessary corporate action, including any required
              approval of the shareholders of NVBancorp, to amend its 1998
              Employee Stock Incentive Plan or establish a new stock option plan
              and cause to be filed and become effective under the Securities
              Act of 1933, as amended, a registration statement with respect to
              the options to be granted and shares to be issued thereunder to
              fulfill the obligations to grant substitute options to holders of
              SRNB options under to the plan of reorganization; and

         o    take all necessary action to list NVBancorp's common stock with
              the Nasdaq Stock Market for trading on the Nasdaq National Market,
              to be effective as soon as practicable following the effective
              time of the merger.

         Under the plan of reorganization, NVBancorp further agreed:

         o    to amend, subject to shareholder approval, its articles of
              incorporation and bylaws to classify its board of directors, and
              to appoint two of the existing directors of SRNB (to be designated
              by NVBancorp) to the classified NVBancorp board of directors; if
              the proposal to classify the NVBancorp board of directors is
              approved by its shareholders, then one appointed director will be
              a class II director and the other appointed director will be a
              class III director, under the classified board structure described
              in "Proposal to Classify Board of Directors;" and

         o    until the effective time of the merger, not to solicit or accept a
              takeover proposal from a third party unless the proposal is
              expressly conditioned upon the performance by NVBancorp or the
              successor in interest of NVBancorp of its obligations under the
              plan of reorganization.

ADDITIONAL AGREEMENTS

         SPECIAL SHAREHOLDERS' MEETINGS. In the plan of reorganization, each of
NVBancorp and SRNB has agreed to call a special meeting of its shareholders to
be held as promptly as practicable for the purpose of voting on the merger. Each
of NVBancorp and SRNB is required through its board of directors to recommend to
its shareholders approval of the plan of reorganization unless its board of
directors determines in good faith, based upon the written advice of outside
counsel, that making the recommendation, or failing to withdraw, modify or amend
any previously made recommendation, would constitute a breach of fiduciary duty
by its board of directors under applicable law.

         NO SOLICITATIONS. Subject to the fiduciary duty of SRNB board of
directors, prior to the effective time of the merger, SRNB has agreed not to
enter into a transaction or series of transactions with one or more third
persons or groups providing for the acquisition of all or a substantial part of
SRNB or its subsidiaries, whether by way of merger, exchange of stock, sale of
assets, or otherwise ("Business Combination") or directly or indirectly. SRNB
also agreed not to acquire or agree to acquire any of its own capital stock or
the capital stock or asset (except in a fiduciary capacity or in the ordinary
course of business) of any other entity, or commence any proceedings for winding
up and dissolution affecting either of them, solicit or encourage any inquiries,
discussions or proposals for any Business Combination with any third party; or
disclose, directly or indirectly, any nonpublic information to any group
concerning SRNB's business, properties, books or records or otherwise encourage
any person, having any actual or prospective role with respect to any Business
Combination. However, in the event the SRNB board receives a bona fide
unsolicited offer for a Business Combination of SRNB with another entity, and
reasonably determines, upon advice of counsel, that as a result of the offer,
any duty to act or to refrain from doing any act under the plan of
reorganization is inconsistent with the continuing fiduciary duties of the board
to its shareholders, subject to the provisions of the plan of reorganization,
including payment of a termination fee to NVBancorp, a violation of SRNB's
covenants described above will be excused and the violation will constitute the
failure of any condition or a breach of the plan of reorganization. If the
merger is terminated because SRNB breaches the agreement against entering into a
Business Combination, SRNB is required to pay to NVBancorp a termination fee.
See "--Termination Fees" on page 63.

         FILINGS AND OTHER ACTIONS. In the plan of reorganization, NVBancorp and
SRNB have each agreed to use all reasonable efforts:

         o    to take all actions necessary to comply promptly with all legal
              requirements which may be imposed on each party or its
              subsidiaries with respect to the transactions contemplated by the
              plan of reorganization; and

         o    to obtain (and to cooperate with the other party to obtain) any
              governmental or private consent, authorization, order, exemption
              or approval which is required to be obtained or made by each party
              or any of its subsidiaries in connection with the merger and the
              other transactions contemplated by the plan of reorganization. In
              addition, each of SRNB and NVBancorp has agreed to use its best
              efforts to take all actions necessary and proper or advisable to
              complete, as soon as practicable, the transactions contemplated by
              the plan of reorganization.

         EMPLOYEE BENEFIT PLANS. Under the plan of reorganization, SRNB's
employee benefits plans will be terminated, frozen, modified or merged into
NVBancorp's employee benefit plans as determined by the agreement of the parties
and in accordance with applicable law. Additionally, SRNB employees who become
employees of NVBancorp or North Valley Bank will be entitled to participate in

                                      -56-
<PAGE>


NVBancorp's employee benefits plans and will receive credit for his or her years
of employment by SRNB. For a period of one year after the closing date, each
SRNB employee who continues his or her employment with SRNB, NVBancorp or North
Valley Bank after the closing date will continue to be entitled to the benefit
of the SRNB severance policy.

         INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE. Under the plan of
reorganization, from and after the effective date, NVBancorp will indemnify and
hold harmless each present or former officer or director of SRNB (determined as
of the effective time) against all losses, claims, damages, liabilities, costs,
expenses or judgments or amounts that are paid in the settlement of or in
connection with any claim, action, suit, proceeding or investigation based on or
arising out of (1) the fact that the person is or was a director or officer of
SRNB and (2) the plan of reorganization or the transactions contemplated by the
plan of reorganization, in each case to the full extent permitted by law.

         Additionally, from and after the effective date, NVBancorp will include
in its director and officer insurance policy persons who served as directors and
officers of SRNB or obtain extended coverage under SRNB's director and officer
insurance policy to cover claims made for a period of three years after the
effective date of the merger regarding acts or omissions of SRNB's directors or
officers prior to the effective date of the merger. However, NVBancorp will not
be obligated to make annual premium payments for the insurance to the extent the
premiums exceed 150% of the premiums paid by SRNB for the insurance, as
previously disclosed to NVBancorp. If the premiums for the insurance would at
any time exceed 150% of the premiums paid by SRNB for the insurance, then
NVBancorp will maintain policies of insurance which, in NVBancorp's good faith
determination, provide a maximum coverage available at an annual premium equal
to 150% of the premiums paid by SRNB in respect of the insurance. See
"Comparison of Shareholder Rights--Indemnification of Directors and Executive
Officers" on page 83.

         The representations and warranties of NVBancorp and SRNB terminate as
of the effective time of the merger.

CONDITIONS TO THE COMPLETION OF THE MERGER

         The merger will occur only if certain conditions are satisfied, unless
we agree to waive any condition that is not satisfied. It is not certain when or
if the conditions to the merger will be satisfied or waived, or if the merger
will be consummated.

         Each party's obligation to complete the merger is subject to various
conditions which include the following, in addition to other customary closing
conditions:

         o    The plan of reorganization and the terms of the merger must be
              approved by the affirmative vote or consent of shareholders
              holding at least a majority of the outstanding shares of NVBancorp
              common stock and at least two-thirds of the outstanding shares of
              SRNB common stock.

         o    All necessary governmental filings must have been made and all
              necessary governmental approvals must have been obtained and be in
              effect. In addition, no governmental approval must require either
              of us to divest or cease any of our present businesses or
              operations or impose any other condition or requirement which we,
              in our reasonable judgment, consider to be materially burdensome.

         o    No legal, administrative, arbitration, investigatory or other
              proceeding by any governmental or regulatory authority which seeks
              to restrain or prohibit the merger must have been commenced or be
              threatened.

         o    The registration statement must have been declared effective and
              must not be subject to a stop order of the SEC, and no proceedings
              for that purpose must have been initiated or threatened by the
              SEC. In addition, the shares of NVBancorp common stock included in
              the registration statement must have received all permits or
              approvals required under all applicable state securities laws.

         o    Each of us must have received a tax opinion from McCutchen, Doyle,
              Brown & Enersen, LLP, legal counsel to SRNB, based on customary
              assumptions and exceptions and factual statements and
              representations provided by the parties, substantially to the
              effect that, under federal income tax law and California income
              and franchise tax law: (a) the merger will not result in any
              recognized gain or loss to NVBancorp or SRNB; (b) except for cash
              received in lieu of any fractional share, no gain or loss will be
              recognized by holders of SRNB common stock who receive shares of
              NVBancorp common stock in exchange for the shares of SRNB common
              stock they hold; (c) the holding period for the shares of
              NVBancorp common stock issued in exchange for the shares of SRNB
              common stock in the merger will include the holding period of the
              shares of the SRNB common stock for which they are exchanged,
              assuming that the shares of SRNB common stock are capital assets
              in the hands of the SRNB shareholder at the effective date of the
              merger; (d) the basis of the shares of NVBancorp common stock
              received by the SRNB shareholders in the merger will be the same
              as the basis of the shares of SRNB common stock for which they are
              exchanged, less any basis attributable to fractional shares for
              which cash is received, and (e) any SRNB shareholder who dissents
              to the merger and receives cash for his or her shares of SRNB
              common stock will be treated as having received a distribution in
              redemption of his or her shares of SRNB common stock, subject to
              the provisions and limitations of section 302 of the Internal
              Revenue Code.

         o    NVBancorp must receive a letter from NVBancorp's independent
              accountants that no conditions exist that would preclude
              accounting for the merger as a pooling-of-interests and SRNB must
              receive a letter from SRNB's independent accountants to the effect
              that no conditions exist that would preclude SRNB from being a
              party to a business combination to be accounted for as a
              pooling-of-interests. In addition, no determination by any court,
              governmental or regulatory agency must have been made that the
              merger fails or will fail to qualify for pooling-of-interests
              accounting treatment.

         o    Each party must have received an opinion from its financial
              advisor, dated within three days prior to the date this joint
              proxy statement/prospectus is mailed to you, to the effect that
              the conversion ratio is fair, from a financial point of view, to
              that party and its shareholders, and the opinion must not have
              been withdrawn prior to the effective time of the merger. Alex
              Sheshunoff & Co. Investment Banking, L.P. is the financial advisor
              to NVBancorp and Hoefer & Arnett Incorporated is the financial
              advisor to SRNB.

         o    The representations and warranties that each of us have made in
              the plan of reorganization must remain true and correct in all
              material respects as of the closing date and effective time of the
              merger; and each of us must have performed and complied, in all
              material respects, with all of the agreements we made in the plan
              of reorganization at or prior to the effective time of the merger.

         o    Each party must have received a certificate signed by the other
              party's president and chief financial officer to the effect that
              the representations and warranties of each party set forth in the
              plan of reorganization, subject to the disclosure schedules
              delivered by each party to the other party on or prior to the
              closing date, are true and correct in all material respects as of
              the closing date.

         o    Holders of not more than ten percent (10%) of the outstanding
              shares of SRNB common stock and NVBancorp common stock must have
              perfected their dissenter's rights in the manner required by the
              National Bank Act and the rules and regulations of the Office of
              the Comptroller of the Currency, and under Chapter 13 of the
              California General Corporation Law, as applicable.

         o    Each party must have received from the other party the
              certificates and other closing documents that their counsel
              reasonably requires in order to close the merger.

         o    We must have received signed affiliate agreements on or before the
              date this joint proxy statement/prospectus is mailed to you, from
              each person who, in our opinion, might be deemed to be an
              affiliate of SRNB or NVBancorp under Rule 144 or Rule 145 of the
              Securities Act of 1933, as amended. The affiliate agreements
              include provisions restricting certain actions by the affiliates
              of NVBancorp and SRNB, including the purchase, sale or other
              transfer of shares of NVBancorp common stock or SRNB common stock
              in a manner that could prevent the merger from qualifying for
              pooling-of-interest accounting treatment.

         o    Our boards of directors and executive officers must have delivered
              to us signed shareholder agreements, before this joint proxy
              statement/prospectus is mailed, under which they agree to vote
              their shares of NVBancorp common stock and SRNB common stock,
              respectively, in favor of the merger under the plan of
              reorganization, and to recommend to shareholders that they also
              vote in favor of the merger.

                                      -59-

         The obligation of NVBancorp to consummate the merger is subject to the
following additional conditions:

              month periods then ended from SRNB's independent public

              the month ended at least 10 business days prior to the effective
              date of the merger.

         o    SRNB must have received, or NVBancorp must be satisfied that SRNB

              NVBancorp must not have become a party to or threatened with any

              financial condition, results of operations or assets of NVBancorp
              and North Valley Bank taken together.

              effect at the closing date.

TERMINATION OF THE PLAN OF REORGANIZATION

         We can agree at any time to terminate the plan of reorganization
without completing the merger, even if the shareholders of both NVBancorp and
SRNB have approved it. Also, the plan of reorganization can be terminated either
by our mutual agreement or by one of us if certain events occur. If the plan of
reorganization is terminated, the merger will not occur.

         Either NVBancorp or SRNB can terminate the plan of reorganization if
any of the following events occurs:

         o    If the merger is not completed by March 31, 2000 or another date
              that we approve; provided, however, that if the only conditions to
              the closing that remain unsatisfied at March 31, 2000 (or other
              date that we approve) are the receipt of any requisite
              governmental approvals or the expiration of any legally required
              waiting periods, then the closing will be automatically extended
              to May 31, 2000 or other date we approve.

         o    Thirty days after any governmental agency denies or refuses to
              grant an approval, consent or qualification that is required for
              the merger, unless we agree, during the 30 day period, to appeal
              the denial or refusal or we agree to file an amended application
              for the governmental approval, consent or qualification.

         o    The shareholders of either NVBancorp or SRNB fail to approve the
              plan of reorganization and related transactions, including the
              merger, by the required vote.

         NVBancorp can elect to terminate the plan of reorganization if any of
the following events occur:

         o    Any of the conditions to NVBancorp's obligations to complete the
              merger under the plan of reorganization have not been satisfied or
              waived by March 31, 2000 (or other date that we may approve).

         o    A material adverse change has occurred since June 30, 1999 in the
              business, financial condition, results of operations or assets of
              SRNB.

                                      -61-
<PAGE>


         o    SRNB or any of its affiliates enters into a transaction or series
              of transactions with one or more third persons providing for the
              acquisition of all or a substantial part of SRNB or its
              subsidiaries, whether by way of merger, exchange or stock, sale of
              assets, or otherwise.

         o    SRNB breaches or fails to satisfy any of its agreements in the
              plan of reorganization which would materially impair the benefits
              reasonably expected to be derived by NVBancorp and North Valley
              Bank from the merger, unless the breach or failure is waived by
              NVBancorp or cured by SRNB within 45 days after NVBancorp gives
              SRNB written notice of the breach or failure.

         o    SRNB fails to deliver to NVBancorp the shareholder agreements,
              affiliates agreements, officer's certificate or opinion of SRNB's
              legal counsel which are required by the plan of reorganization or
              if those documents are not in a form that is reasonably acceptable
              to NVBancorp.

         SRNB can elect to terminate the plan of reorganization if any of the
following events occur:

         o    Any of the conditions to SRNB's obligations to complete the merger
              under the plan of reorganization have not been satisfied or waived
              by March 31, 2000 (or other date that we may approve).

         o    A material adverse change has occurred since June 30, 1999 in the
              business, financial condition, results of operations or assets of
              NVBancorp.

         o    NVBancorp solicits or accepts any offer from any third party
              providing for the acquisition of all or a substantial part of
              NVBancorp or North Valley Bank, whether by way of merger, exchange
              or stock, sale of assets, or otherwise, unless the offer is
              expressly conditioned on the performance by NVBancorp or its
              successor of NVBancorp's obligations under the plan of
              reorganization.

         o    NVBancorp breaches or fails to satisfy any of its agreements in
              the plan of reorganization which would materially impair the
              benefits reasonably expected to be derived by SRNB from the
              merger, unless the breach or failure is waived by SRNB or cured by
              NVBancorp within 45 days after SRNB gives NVBancorp written notice
              of the breach or failure.

         o    NVBancorp fails to deliver to SRNB the shareholder agreements,
              affiliates agreements, officer's certificate or opinion of
              NVBancorp's legal counsel which are required by the plan of
              reorganization or if those documents are not in a form that is
              reasonably acceptable to SRNB.

         SRNB also has the option to terminate the plan of reorganization within
two business days after the "determination date" if the average closing price of
NVBancorp common stock for the 20 trading days ending on the determination date
is less than $10.00. The "determination date" is the last day of the 20 trading
day period ending on the their business day prior to the closing date.

         Any termination described above must be made by written notice from the
party seeking termination to the other party. In the event the plan of
reorganization is terminated, it will become void and have no effect, except
that the termination will not affect the provisions regarding payment of
expenses, confidentiality, payment of any termination fees if applicable or any
relevant general provisions of the plan of reorganization. Also, if the plan of
reorganization is terminated due to a party's breach, the termination will not
relieve the breaching party from its liability and the non-breaching party will
retain all of its legal rights and remedies against the breaching party for its
breach.

TERMINATION FEES

         SRNB is required to pay NVBancorp $2.0 million in liquidated damages if
NVBancorp terminates the plan of reorganization for any of the following
reasons:

         o    if SRNB or its affiliates enters into an agreement by which SRNB
              or its subsidiaries would be acquired by another entity;

         o    if SRNB breaches any covenant in the plan of reorganization which
              materially impairs the benefit of the merger to NVBancorp, unless
              SRNB cures the breach within 45 days after written notice from
              NVBancorp; or

         o    if SRNB willfully or deliberately refuses to deliver to NVBancorp
              certain closing documents required by the plan of reorganization.

         NVBancorp is required to pay SRNB $2.0 million in liquidated damages if
SRNB terminates the plan of reorganization for any of the following reasons:

         o    if NVBancorp solicits or accepts an offer from a third party to
              acquire NVBancorp or North Valley Bank and the offer does not
              require NVBancorp or the third party to comply with the plan of
              reorganization;

         o    if NVBancorp breaches any covenant in the plan of reorganization
              which materially impairs the benefit of the merger to SRNB, unless
              NVBancorp cures the breach within 45 days after written notice
              from SRNB; or

         o    if NVBancorp willfully or deliberately refuses to deliver to SRNB
              certain closing documents required by the plan of reorganization.

FEES AND EXPENSES OF THE MERGER

         Other than in the situations described above and in the following
paragraphs, whether or not the merger is completed in accordance with the plan
of reorganization, all costs and expenses incurred in connection with the plan
of reorganization and the transactions covered by the plan of reorganization
will be paid by the party incurring those expenses.

         NVBancorp and SRNB will each bear the costs of distributing this joint
proxy statement/ prospectus and other proxy materials and information relating
to the plan of reorganization to its shareholders and of conducting a meeting of
its shareholders, but each party will pay one-half of the printing costs, the
fees and costs related to obtaining a tax opinion and the fees and costs related
to obtaining a letter from their independent auditors regarding
pooling-of-interests accounting treatment.

         If the plan of reorganization is terminated by NVBancorp or SRNB
because holders of more than 10 percent of the outstanding shares of NVBancorp
common stock and SRNB common stock have dissented from the plan of
reorganization and merger and have perfected their dissenters' rights, then each
party will pay one-half of (1) all fees and costs payable under state "blue sky"
securities laws, (2) the fee required to be paid to the Securities and Exchange
Commission to register the shares of NVBancorp common stock, (3) the fees and

                                      -63-

Plan or for the preparation of a new NVBancorp stock option plan for the SRNB
optionees, and (4) the fees related to preparation and filing of applications to
governmental agencies for approval of the plan of reorganization and merger, in
addition to the three categories of expenses described in the immediately
preceding paragraph.

         The fees and costs related to the listing of the shares of NVBancorp
common stock with the Nasdaq National Market will be paid by NVBancorp.

AMENDMENT

         The plan of reorganization may be amended by the parties at any time
before or after approval of the plan of reorganization by the shareholders of
NVBancorp and SRNB. However, after the approval by the shareholders of NVBancorp
and SRNB, no amendment will be made which by law requires further approval by
those shareholders without that further approval. The plan of reorganization may
not be amended except by an instrument in writing signed on behalf of each of
the parties.

EXTENSION; WAIVER

         At any time prior to the closing of the merger, the parties, by action
taken or authorized by their respective board of directors, may, to the extent
legally allowed, (1) extend the time for the performance of any of the
obligations or other acts of the other parties, (2) waive any inaccuracies in
the representations and warranties contained in the plan of reorganization or in
any document delivered under it, and (3) waive compliance with any of the
agreements or conditions contained in the plan of reorganization. To "waive"
means to give up rights.

         Any agreement on the part of a party to the plan of reorganization to
any extension or waiver will be valid only if set forth in a written instrument
signed on behalf of the party.

MANAGEMENT AND OPERATIONS FOLLOWING THE MERGER

         Upon the consummation of the merger, the separate corporate existence
of SRNB will cease and SRNB will be merged with and into NVB Interim National
Bank. All rights, franchises and interests of SRNB will be assumed by and vested
in NVB Interim National Bank and the resulting bank will continue as a
subsidiary of NVBancorp with the national bank charter number and name of Six
Rivers National Bank. The directors and executive officers of SRNB prior to the
effective date will be the directors and executive officers of SRNB following
the merger except that two of the existing directors of NVBancorp will become
directors of the resulting bank. In addition, (1) two SRNB directors will be
added to the boards of directors of NVBancorp and (2)Michael W. Martinez,
President and Chief Executive Officer of SRNB, will be appointed to serve on the
executive management committee of NVBancorp.

REQUIRED REGULATORY APPROVALS

         The merger must be approved by the Board of Governors of the Federal
Reserve System (the "Federal Reserve Board") under the provisions of the Bank
Holding Company Act of 1956, as amended. In conducting a review of any
application for a merger, the Federal Reserve Board is required to consider the
financial and managerial resources and future prospects of the banks concerned
and the convenience and needs of the community to be served. The Federal Reserve
Board has the authority to deny an application if it concludes that the
requirements of the Community Reinvestment Act of 1977, as amended, are not
satisfied.

                                      -64-
<PAGE>


         NVBancorp filed an application for approval with the Federal Reserve
Board on ______________, 2000. A transaction approved by the Federal Reserve
Board may not be consummated for at least 30 days (in some circumstances a
15-day waiting period is allowed) after the approval. During that period, the
Department of Justice may commence a legal action challenging the transaction
under federal antitrust laws. If the Department of Justice does not commence a
legal action during the 30-day period (in some circumstances a 15-day waiting
period is allowed), it may not thereafter challenge the transaction except in an
action commenced under the antimonopoly provisions of Section 2 of the Sherman
Antitrust Act.

         The Bank Holding Company Act of 1956. as amended, provides for the
publication of notice and the opportunity for administrative hearings relating
to an application for approval under the Act and authorizes the Federal Reserve
Board to permit interested parties to intervene in the proceedings. If an
interested party is permitted to intervene, the intervention could substantially
delay the regulatory approval required for consummation of the merger.

         The merger of SRNB and NVB Interim National Bank is subject to the
prior approval of the Office of the Comptroller of the Currency under Section
18(c) of the Federal Deposit Insurance Act, as amended (the "Bank Merger Act")
and Section 215a of the National Bank Act, as amended. NVBancorp filed an
application for approval of the merger with the Office of the Comptroller of the
Currency on ______________, 2000.

         The application filed with the Office of the Comptroller of the
Currency includes an application for approval to organize an interim national
bank, named NVB Interim National Bank. Interim national banks are federally
chartered banks established to facilitate interim bank mergers and they do not
operate as banks in their own right. Nonetheless, they must comply with
chartering and organization requirements. The directors of NVBancorp are the
organizers of NVB Interim National Bank and they will serve as its board of
directors. Upon receipt of preliminary approval to organize, the organizers of
NVB Interim National Bank will file articles of association with the Office of
the Comptroller of the Currency and will comply with the other conditions stated
in the preliminary approval. Once organized, NVB Interim National Bank will
become a party to the plan of reorganization by entering into an addendum with
NVBancorp and SRNB.

         The Bank Merger Act requires the Office of the Comptroller of the
Currency, when approving a transaction like the merger, to take into
consideration the financial and managerial resources (including the competence,
experience and integrity of the officers, directors and principal shareholders)
and future prospects of the existing and proposed institutions and the
convenience and needs of the communities to be served. In considering financial
resources and future prospects, the Office of the Comptroller of the Currency
will, among other things, evaluate the adequacy of the capital levels of the
parties to a proposed transaction and of the resulting institutions.

         On April 12, 1999 the Office of the Comptroller of the Currency
required SRNB to enter into a Consent Order. The language of the Order requires
that SRNB formulate and implement a plan to strengthen its policies and
procedures relative to its loan administration, credit and collateral
exceptions, classified assets, allowances for loan losses and violations of law
related to lending limits. The SNRB board of directors agreed to execute the
Order and is following an action plan that details the steps necessary to comply
with the Order. In summary, the Order required SRNB to modify certain aspects of
its business to address problems identified by the Office of the Comptroller of
the Currency, such as:

         o    loan administration (to establish procedures to ensure compliance
              with credit quality guidelines, govern board of directors review
              and approval of exceptions to lending policies, require periodic

                                      -65-
<PAGE>


              board of directors review of adherence to lending policies and
              ensure accuracy of information systems and other operational
              programs);

         o    credit and collateral exceptions (to update background information
              on each loan);

         o    criticized assets (to address issues raised by the Office of the
              Comptroller of the Currency during the evaluation and analysis of
              SRNB's asset quality and provide ongoing board of directors review
              of each issue and the adequacy and progress of SRNB's ongoing
              monitoring of asset quality);

         o    allowance for loan and lease losses (to establish a program to
              maintain adequate allowances providing for scheduled reviews by
              the board of directors);

         o    legal lending limits (to take prompt action to reduce overlimit
              loans and establish compliance procedures regarding the
              maintenance of appropriate loan limits); and

         o    quarterly progress reports (to submit quarterly progress reports
              to the Office of the Comptroller of the Currency outlining recent
              actions taken to implement the Order).

The Order's restrictions could have an adverse impact on SRNB's expansion.
Additional regulatory restrictions could be placed on SRNB in the event that the
Office of the Comptroller of the Currency is not satisfied with SRNB's progress
towards implementing all facets of the Order. There can be no assurance as to
the impact on SRNB or NVBancorp if banking regulators impose additional
regulatory restrictions on SRNB.

         This summary description of the Order's provisions does not state all
the requirements of the Order and is qualified in its entirety by reference to
the text of the Order. A copy of the Order will be made available (free of
charge) to any shareholder of NVBancorp or SRNB upon request to Michael W.
Martinez, President and Chief Executive Officer of SRNB. See "Where You Can Find
More Information" on page 97.

         The Bank Merger Act prohibits the Office of the Comptroller of the
Currency from approving a merger if it would result in a monopoly or be in
furtherance of any combination or conspiracy to monopolize or to attempt to
monopolize the business of banking in any part of the United States, or if its
effect in any section of the country would be substantially to lessen
competition or to tend to create a monopoly, or if it would in any other manner
result in a restraint of trade, unless the Office of the Comptroller of the
Currency finds that the anti-competitive effects of the merger are clearly
outweighed in the public interest by the probable effect of the transaction in
meeting the convenience and needs of the communities to be served. In addition,
under the Community Reinvestment Act of 1977, as amended, the Office of the
Comptroller of the Currency must take into account the record of performance of
the existing institutions in meeting the credit needs of the entire community,
including low- and moderate-income neighborhoods, served by those institutions.

         The Office of the Comptroller of the Currency will furnish notice and a
copy of the application for approval of the merger to the Federal Reserve Board,
the Federal Deposit Insurance Corporation and the United States Department of
Justice. These agencies have 30 days to submit their views and recommendations
to the Office of the Comptroller of the Currency. The Bank Merger Act also
provides for the publication of notice and public comment on applications filed
with the Office of the Comptroller of the Currency and authorizes the agency to
permit interested parties to intervene in the proceedings. If an interested
party is permitted to intervene, the intervention could delay the regulatory
approvals required for completion of the merger.

                                      -66-
<PAGE>

         SRNB and NVBancorp do not believe that the merger will raise
substantial antitrust or other significant regulatory concerns and that they
will be able to obtain all requisite regulatory approvals on a timely basis
without the imposition of any condition that would have a material adverse
effect.

         Under the plan of reorganization, prior to the merger, all governmental
approvals required for the merger will be in effect, and all conditions or
requirements prescribed by law or any governmental approval will be satisfied.
However, no governmental approval will be deemed to have been received if it
will require the divestiture or cessation of any of the present businesses or
operating conducted by the parties or imposes any condition or requirement
which, in the reasonable opinion of the board of directors of NVBancorp is
deemed to be materially burdensome.

         Based on current precedents, the respective managements of NVBancorp
and SRNB believe that the merger and other consents and approvals will be
approved by the Federal Reserve Board and the Office of the Comptroller of the
Currency and the merger will not be subject to challenge by the Department of
Justice under federal antitrust laws. However, no assurance can be provided that
the Federal Reserve Board, the Office of the Comptroller of the Currency or the
Department of Justice will concur in this assessment or that, in connection with
the grant of any approval by the Federal Reserve Board or the Office of the
Comptroller of the Currency, action taken, or statute, rule, regulation or order
enacted, entered, enforced or deemed applicable to the merger or transactions
contemplated thereby, will not contain conditions or requirements which are
materially burdensome as further described in the plan of reorganization. If any
materially burdensome condition or requirement is imposed in connection with a
governmental approval, a condition to NVBancorp's obligation to consummate the
merger will be deemed not to have occurred and NVBancorp will have the right to
terminate the plan of reorganization.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following discussion summarizes the material United States federal
income tax consequences of the merger. The discussion does not address all
aspects of United States federal taxation that may be relevant to you, and it
may not be applicable to SRNB shareholders who, for United States federal income
tax purposes, are nonresident alien individuals, foreign corporations, foreign
partnerships, foreign trusts or foreign estates, or who acquired their SRNB
common stock by the exercise of SRNB stock options or otherwise as compensation.
YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF
THE MERGER TO YOU.

         This discussion is based on the Internal Revenue Code of 1986, as
amended, regulations thereunder, current administrative rulings and practice,
and judicial precedent, all of which are subject to change. Any change, which
may or may not be retroactive, could alter the tax consequences to you as
discussed in this joint proxy statement/prospectus. This discussion assumes that
you hold your SRNB common stock as a capital asset within the meaning of section
1221 of the Internal Revenue Code.

         NVBancorp's and SRNB's obligation to complete the merger is conditioned
upon NVBancorp and SRNB receiving an opinion of McCutchen, Doyle, Brown &
Enersen, LLP, based upon certain customary assumptions, exceptions and
representations made by NVBancorp and SRNB, to the effect that under federal
income tax law and California income and franchise tax law:

         o    the merger will not result in any recognized gain or loss to
              NVBancorp or SRNB;

         o    except for any cash received in lieu of any fractional share, no
              gain or loss will be recognized by the holders of SRNB common
              stock who receive NVBancorp common stock in exchange for the SRNB
              common stock which they hold;

                                      -67-
<PAGE>

         o    the holding period of the NVBancorp common stock exchanged for
              SRNB common stock (including any fractional share prior to its
              conversion to cash) will include the holding period of the SRNB
              common stock for which it is exchanged, assuming the shares of
              SRNB common stock are capital assets in the hands of the holder
              thereof at the effective date;

         o    the basis of the NVBancorp common stock received in the exchange
              (including any fractional share prior to its conversion to cash)
              will be the same as the basis of the SRNB common stock for which
              it was exchanged, less any basis attributable to fractional shares
              for which cash is received; and

         o    an SRNB shareholder who dissents to the merger and receives cash
              for his or her SRNB common stock will be treated as having
              received a distribution in redemption of his or her SRNB common
              stock, subject to the provisions and limitations of Section 302 of
              the Internal Revenue Code.

         McCutchen, Doyle, Brown & Enersen, LLP has indicated that it expects to
be able to deliver its tax opinion. Opinions of counsel are not binding on the
Internal Revenue Service or the courts and no ruling has been or will be
obtained from the Internal Revenue Service in connection with the merger.

         THE FOREGOING IS A GENERAL DISCUSSION OF THE MATERIAL UNITED STATES
FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND IS INCLUDED FOR GENERAL
INFORMATION ONLY. THE FOREGOING DISCUSSION DOES NOT TAKE INTO ACCOUNT THE
PARTICULAR FACTS AND CIRCUMSTANCES OF YOUR STATUS AND ATTRIBUTES. AS A RESULT,
THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES ADDRESSED IN THE FOREGOING
DISCUSSION MAY NOT APPLY TO YOU. IN VIEW OF THE INDIVIDUAL NATURE OF INCOME TAX
CONSEQUENCES, YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISOR TO DETERMINE THE
SPECIFIC TAX CONSEQUENCES OF THE MERGER TO YOU, INCLUDING THE APPLICATION AND
EFFECT OF UNITED STATES FEDERAL, STATE, LOCAL AND OTHER TAX LAWS AND THE
POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL AND OTHER TAX LAWS.

ACCOUNTING TREATMENT

         For accounting and financial reporting purposes, the merger is expected
to qualify as a pooling of interests of SRNB by NVBancorp under generally
accepted accounting principles. Under the pooling of interests accounting
method, NVBancorp will carry forward on its books the assets and liabilities of
SRNB at their historical recorded values, subject to any adjustments required to
conform the accounting policies and financial statement classification of the
two companies. Income of the combined NVBancorp will include income of NVBancorp
and SRNB for the entire fiscal year in which the combination occurs and the
reported income, assets, liabilities and shareholders' equity of the separate
companies for previous periods will be combined and restated as income, assets,
liabilities and shareholders' equity of NVBancorp. The unaudited pro forma
combined financial information contained in this joint proxy
statement/prospectus have been prepared using the pooling of interests method of
accounting to account for the merger. See "Summary--Selected Historical and Pro
Forma Financial Data" and "Unaudited Pro Forma Condensed Combined Financial
Information" on page 72.

TRADING MARKETS FOR STOCK

         The NVBancorp common stock is listed on the Nasdaq National Market.
NVBancorp intends to cause the shares of NVBancorp common stock to be issued in
the merger and the shares of NVBancorp common stock to be reserved for issuance
upon the exercise of existing SRNB stock options to be approved for listing on
the Nasdaq National Market, subject to official notice of issuance, prior to the
effective date.

                                      -68-
<PAGE>


         The SRNB common stock is currently listed on the Nasdaq National
Market. If the merger is consummated, NVBancorp will take action to cause the
SRNB shares to cease to be listed on the Nasdaq National Market and public
trading of the SRNB shares will cease.

RESALES OF NVBANCORP COMMON STOCK

         The NVBancorp common stock issued in the merger will be freely
transferable under the Securities Act of 1933, as amended, except for shares
issued to any SRNB shareholder who may be deemed to be an "affiliate" of
NVBancorp or SRNB for purposes of Rule 145 under the Securities Act of 1933, as
amended. Each director and executive officer of SRNB is deemed to be an
affiliate. Each SRNB director and each other person deemed to be an affiliate
has entered into an agreement with NVBancorp providing that the person will not
transfer any shares of NVBancorp common stock received in the merger, except in
compliance with the Securities Act of 1933, as amended, and applicable rules
thereunder.

                               DISSENTERS' RIGHTS

DISSENTERS' RIGHTS OF NVBANCORP SHAREHOLDERS

         Dissenters' rights will be available to the shareholders of NVBancorp
only if the holders of five percent (5%) or more of NVBancorp common stock make
a written demand upon NVBancorp for the purchase of dissenting shares in
accordance with Chapter 13 of the California General Corporation Law ("Chapter
13"). If this condition is satisfied and the merger is consummated, shareholders
of NVBancorp who dissent from the merger by complying with the procedures set
forth in Chapter 13 would be entitled to receive an amount equal to the fair
market value of their shares as of October 1, 1999, the last business day before
the public announcement of the merger. The high, low and closing sales prices
for NVBancorp common stock on October 1, 1999 were $11.063, $10.563 and $11.063,
respectively. A copy of Chapter 13 of the California General Corporation Law is
attached as Annex D to this joint proxy statement/prospectus and should be read
for more complete information concerning dissenters' rights. THE REQUIRED
PROCEDURE SET FORTH IN CHAPTER 13 OF THE CALIFORNIA GENERAL CORPORATION LAW MUST
BE FOLLOWED EXACTLY OR ANY DISSENTERS' RIGHTS MAY BE LOST. The information set
forth below is a general summary of dissenters' rights as they apply to
NVBancorp shareholders and is qualified in its entirety by reference to Annex D.

         In order to be entitled to exercise dissenters' rights, a shareholder
of NVBancorp must vote "AGAINST" the merger. Thus, any NVBancorp shareholder who
wishes to dissent and executes and returns a proxy in the accompanying form must
specify that his or her shares are to be voted "AGAINST" the merger. If the
shareholder returns a proxy without voting instructions or with instructions to
vote "FOR" the merger, his or her shares will automatically be voted in favor of
the merger and the shareholder will lose any dissenters' rights. In addition, if
the shareholder abstains from voting or in the event of a broker non-vote of his
or her shares, the shareholder will lose any dissenters' rights.

         Furthermore, in order to preserve his or her dissenters' rights, an
NVBancorp shareholder must make a written demand upon NVBancorp for the purchase
of dissenting shares and payment to the shareholder of their fair market value,
specifying the number of shares held of record by the shareholder and a
statement of what the shareholder claims to be the fair market value of those
shares as of October 1, 1999. The demand must be addressed to NVBancorp, 880
East Cypress Avenue, Redding, California 96002; Attention: Corporate Secretary,
and must be received by NVBancorp not later than the date of NVBancorp's special
meeting. A vote "AGAINST" the merger does not constitute the written demand.

         If the holders of five percent (5%) or more of the outstanding shares
of NVBancorp common stock have submitted a written demand for NVBancorp to
purchase their shares, these demands are received by NVBancorp on or before the
date of the special meeting and the merger is approved by the shareholders,
NVBancorp will have 10 days after the approval to send to those shareholders who
have voted against the approval of the merger written notice of the approval
accompanied by a copy of Chapter 13, a statement of the price determined by
NVBancorp to represent the fair market value of the dissenting shares as of
October 1, 1999, and a brief description of the procedure to be followed if a
shareholder desires to exercise dissenters' rights. Within 30 days after the
date on which the notice of the approval of the merger is mailed, the dissenting
shareholder must surrender to NVBancorp, at the office designated in the notice
of approval, the certificates representing the dissenting shares to be stamped
or endorsed with a statement that they are dissenting shares or to be exchanged
for certificates of appropriate denomination so stamped or endorsed. Any shares
of NVBancorp common stock that are transferred prior to their submission for
endorsement lose their status as dissenting shares.

         If NVBancorp and the dissenting shareholder agree that the surrendered
shares are dissenting shares and agree upon the price of the shares, the
dissenting shareholder will be entitled to the agreed price with interest
thereon at the legal rate on judgments from the date of the agreement. Payment
of the fair market value of the dissenting shares will be made within 30 days
after the amount thereof has been agreed upon or 30 days after any statutory or
contractual conditions to the merger have been satisfied, whichever is later,
subject to the surrender of the certificates therefor, unless provided otherwise
by agreement.

         If NVBancorp denies that the shares surrendered are dissenting shares,
or NVBancorp and the dissenting shareholder fail to agree upon a fair market
value of the shares of NVBancorp common stock, then the dissenting shareholder
of NVBancorp must, within six months after the notice of approval is mailed,
file a complaint at the Superior Court of the proper county requesting the court
to make the determinations or intervene in any pending action brought by any
other dissenting shareholder. If the complaint is not filed or intervention in a
pending action is not made within the specified six-month period, the
dissenters' rights are lost. If the fair market value of the dissenting shares
is at issue, the court will determine, or will appoint one or more impartial
appraisers to determine, the fair market value.

         A dissenting shareholder may not withdraw his or her dissent or demand
for payment unless NVBancorp consents to the withdrawal.

DISSENTERS' RIGHTS OF SRNB SHAREHOLDERS

         If the plan of reorganization is approved by the required vote of SRNB
shareholders, and is not abandoned or terminated, shareholders of SRNB who did
not vote "FOR" the merger or who give notice in writing at or prior to the
special meeting that the shareholder dissents, may be entitled to certain
dissenters' rights under Section 215a(b),(c) and (d) of Title 12 of the United
States Code. A copy of Section 215a(b), (c) and (d) and Office of the
Comptroller of the Currency Banking Circular 259 are attached as Annex E to this
joint proxy statement/prospectus and should be read for more complete
information concerning dissenters' rights. Banking Circular 259 describes the
specific requirements of the appraisal process conducted by the Office of the
Comptroller of the Currency discussed below and includes examples of appraisal
results in various transactions. . THE REQUIRED PROCEDURE SET FORTH IN SECTION
215A(B), (C) AND (D) OF TITLE 12 OF THE UNITED STATES CODE MUST BE FOLLOWED
EXACTLY OR ANY DISSENTERS' RIGHTS MAY BE LOST. The information set forth below
is a general summary of dissenters' rights as they apply to SRNB shareholders
and is qualified in its entirety by reference to Annex E.

                                      -70-
<PAGE>


         In order to be entitled to exercise dissenters' rights, a shareholder
of SRNB must vote "AGAINST" the merger or give notice in writing at or prior to
the special meeting that the shareholder dissents. Thus, any SRNB shareholder
who executes and returns a proxy in the accompanying form must specify that his
or her shares are to be voted "AGAINST" the merger. If the shareholder returns a
proxy without voting instructions or with instructions to vote "FOR" the merger,
his or her shares will automatically be voted in favor of the merger and the
shareholder will lose any dissenters' rights. In addition, if the shareholder
abstains from voting his or her shares, the shareholder will lose his or her
dissenters' rights.

         Furthermore, in order to preserve his or her dissenters' rights, an
SRNB shareholder must make a written demand upon SRNB for the purchase of
dissenting shares and payment to the shareholder of the fair market value. The
written demand must be made prior to thirty days after the date of consummation
of the merger, and be accompanied by the surrendered certificates representing
the dissenting SRNB shareholders' interest in SRNB common stock. NVBancorp will
mail notice of the date of consummation of the merger immediately after
consummation to all dissenting SRNB shareholders, together with a letter of
transmittal for their use in submitting their SRNB stock certificates to
NVBancorp for payment. A vote "AGAINST" the merger does not constitute the
required written demand.

         The value of the SRNB common stock to be purchased by NVBancorp from
dissenting SRNB shareholders will be determined as of the effective date of the
merger, by an appraisal made by a committee of three persons, one selected by
the majority vote of the dissenting SRNB shareholders, one by the directors of
SRNB and one by the two so selected. The valuation agreed upon by any two of the
three appraisers will govern. The appraisers will determine the value of any
dissenting shares within ninety days from the date of consummation of the
merger. In the event that any one or more appraiser is not selected or the
appraisers fail to determine the value of the dissenting shares within this
ninety day time period, any party may request an appraisal to be made by the
Office of the Comptroller of the Currency, which appraisal will be final and
binding on all parties.

         If the valuation determined by the appraiser is unsatisfactory to any
dissenting SRNB shareholder, that shareholder may appeal to the Office of the
Comptroller of the Currency within five days after being notified of the
appraised value of the shares. In this event, the Office of the Comptroller of
the Currency will cause a reappraisal to be made and this reappraisal will be
final and binding as to the value of the shares of the appealing SRNB
shareholder. The expenses of the Office of the Comptroller of the Currency
incurred in making the appraisal or reappraisal, as the case may be, will be
paid by the resulting bank.

                          UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL INFORMATION

         The following Unaudited Pro Forma Condensed Combined Balance Sheet as
of September 30, 1999, combines the historical consolidated balance sheets of
NVBancorp and SRNB as if the merger had been effective on September 30, 1999,
after giving effect to certain adjustments. These adjustments are based on
estimates. The Unaudited Pro Forma Condensed Combined Statements of Operations
for the nine months ended September 30, 1999 and 1998 and for the years ended
December 31, 1998, 1997 and 1996 present the combined results of operations of
NVBancorp and SRNB as if the merger had been effective at the beginning of each
period. The Unaudited Pro Forma Condensed Combined Financial Information has
been prepared from, and should be read in conjunction with, the historical
consolidated financial statements and notes thereto of NVBancorp and SRNB.

         The Unaudited Pro Forma Condensed Combined Financial Information and
accompanying notes reflect the application of the pooling of interests method of
accounting for the merger. Under this method of accounting, the recorded assets,
liabilities, shareholders' equity, income and expenses of NVBancorp and SRNB are
combined and reflected at their historical amounts.

         The pro forma combined figures shown in the Unaudited Pro Forma
Condensed Combined Financial Information are simply arithmetical combinations of
NVBancorp's and SRNB's separate financial results; you should not assume that
NVBancorp and SRNB would have achieved the pro forma combined results if they
had actually been combined during the periods presented.

         THE COMBINED COMPANY EXPECTS TO ACHIEVE MERGER BENEFITS IN THE FORM OF
OPERATING COST SAVINGS. THE PRO FORMA EARNINGS, WHICH DO NOT REFLECT ANY DIRECT
COSTS OR POTENTIAL SAVINGS WHICH ARE EXPECTED TO RESULT FROM THE CONSOLIDATION
OF THE OPERATIONS OF NVBANCORP AND SRNB, ARE NOT INDICATIVE OF THE RESULTS OF
FUTURE OPERATIONS. NO ASSURANCES CAN BE GIVEN WITH RESPECT TO THE ULTIMATE LEVEL
OF EXPENSE SAVINGS. FOR FURTHER EXPLANATION ABOUT THESE RISKS, READ THE
INFORMATION UNDER "INFORMATION REGARDING FORWARD-LOOKING STATEMENTS" AND "RISK
FACTORS."

DIVIDENDS AND DIVIDEND POLICY

         NVBANCORP. NVBancorp's board of directors considers the advisability
and amount of proposed dividends each year. Future dividends will be determined
after consideration of NVBancorp's earnings, financial condition, future capital
funds, regulatory requirements and other factors as the board of directors may
deem relevant. NVBancorp's primary source of funds for payment of dividends to
its shareholders will be receipt of dividends and management fees from North
Valley Bank. The payment of dividends by a bank is subject to various legal and
regulatory restrictions.

                                      -80-
<PAGE>

         From 1993 through 1997, NVBancorp maintained a policy of paying
semi-annual dividends to its shareholders. Effective with the first quarter of
1998, NVBancorp adopted a policy to pay quarterly cash dividends to its
shareholders. NVBancorp has declared and paid cash dividends on its outstanding
shares of common stock totaling $.35 per share in 1997, $.375 per share in 1998
and $.30 per share through September 30, 1999. It is the intention of NVBancorp
to pay cash dividends, subject to the restrictions on the payment of cash
dividends as described above, depending upon the level of earnings, management's
assessment of future capital needs and other factors considered by the NVBancorp
board of directors.

         Holders of NVBancorp common stock are entitled to receive dividends as
and when declared by the board of directors of NVBancorp out of funds legally
available therefor under the laws of the State of California. The California
General Corporation Law 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 California General Corporation Law
further provides that, in the event sufficient retained earnings are not
available for the proposed distribution, a corporation may nevertheless make a
distribution to its shareholders if, after giving effect to the distribution, it
meets two conditions, which generally stated are as follows: (i) the
corporation's assets must equal at least 125% of its liabilities; and (ii) the
corporation's current assets must equal at least its current liabilities or, if
the average of the corporation's earnings before taxes on income and before
interest expense for the two preceding fiscal years was less than the average of
the corporation's interest expense for those fiscal years, then the
corporation's current assets must equal at least 125% of its current
liabilities.

         The Federal Reserve Board generally prohibits a bank holding company
from declaring or paying a cash dividend which would impose undue pressure on
the capital of subsidiary banks or would be funded only through borrowing or
other arrangements that might adversely affect a bank holding company's
financial position. The Federal Reserve Board's policy is that a bank holding
company should not continue its existing rate of cash dividends on its common
stock unless its net income is sufficient to fully fund each dividend and its
prospective rate of earnings retention appears consistent with its capital
needs, asset quality and overall financial condition.

         Under the plan of reorganization, without the prior written consent of
SRNB, NVBancorp is prohibited from declaring or paying any dividends on or
making other distributions in respect of any of its capital stock, except
regular quarterly or semi-annual cash dividends in an amount substantially
equivalent to cash dividends paid in the two years prior to the date of the plan
of reorganization.

         SRNB. SRNB's shareholders are entitled to receive dividends when and as
declared by its board of directors, out of funds legally available therefore,
subject to the restrictions set forth in the National Bank Act.

         The payment of cash dividends by SRNB may be subject to the approval of
the Office of the Comptroller of the Currency, as well as restrictions
established by federal banking law and the Federal Deposit Insurance
Corporation. Approval of the Office of the Comptroller of the Currency is
required if the total of all dividends declared by SRNB's board of directors in
any calendar year will exceed SRNB's net profits for that year combined with its
retained net profits for the preceding two years, less any required transfers to
surplus or to a fund for the retirement of preferred stock. Additionally, the
Federal Deposit and Insurance Corporation and/or Office of the Comptroller of
the Currency, might, under certain circumstances, place restrictions on the
ability of a bank to pay dividends based upon peer group averages and the
performance and maturity of that bank.

         SRNB has not paid cash dividends in 1997, 1998 and 1999. SRNB does not
intend to pay cash or stock dividends prior to the closing of the transactions
contemplated by the plan of reorganization.

         Under the plan of reorganization, without the prior written consent of
NVBancorp, SRNB is prohibited from declaring or paying any dividends on or
making other distributions in respect of any of its capital stock, except
regular quarterly or semi-annual cash dividends in an amount substantially
equivalent to cash dividends paid in the two years prior to the date of the plan
of reorganization.

                        COMPARISON OF SHAREHOLDER RIGHTS

GENERAL

         NVBancorp is incorporated under and subject to the provisions of the
California General Corporation Law. SRNB is a national banking association,
organized under and subject to the National Bank Act.

         Upon consummation of the merger, except for those persons, if any, who
perfect dissenters' rights under the National Bank Act, the shareholders of SRNB
will become shareholders of NVBancorp. See "Dissenters' Rights" on page 69.

         NVBancorp is a California corporation and, accordingly, is governed by
the California General Corporation Law and by its articles of incorporation and
bylaws. SRNB is chartered by the Office of the Comptroller of the Currency and
is governed by the National Bank Act, its articles of Association and bylaws,
which differ in certain material respects from the NVBancorp articles and
NVBancorp bylaws.

         The following is a general comparison of certain similarities and
material differences between the rights of NVBancorp and SRNB shareholders under
their respective governing articles and bylaws. This discussion is only a
summary of certain provisions and is not a complete description of the
similarities and differences, and is qualified in its entirety by reference to
the California General Corporation Law, the National Bank Act, the common law
thereunder and the full text of the NVBancorp articles, NVBancorp bylaws, SRNB
articles and SRNB bylaws.

CERTAIN ANTI-TAKEOVER MEASURES

         Some of the provisions in the NVBancorp articles and the NVBancorp
bylaws discussed below may deter efforts to obtain control of NVBancorp on a
basis which some shareholders might deem favorable. Those provisions are
designed to encourage any person attempting a change in control of NVBancorp to
enter into negotiations with the board of directors of NVBancorp. For example,
the NVBancorp board of directors has authorized a class of preferred stock and
the issuance of rights which may have the effect of delaying or preventing a
change in control of NVBancorp. See "Shareholder Rights Agreement" on page 89,
"Classified Board Provisions" on page 91 and "Description of NVBancorp Capital
Stock--Preferred Stock." on page 92. These anti-takeover measures may decrease
the likelihood that a person or group would obtain control of NVBancorp or may
perpetuate incumbent management.

         The SRNB board of directors has adopted a shareholder rights agreement
which was designed to encourage any person attempting a change in control of
SRNB to enter into negotiations with the board of directors of SRNB. See
"Shareholders Rights Agreement" below.

QUORUM REQUIREMENTS

         Both the NVBancorp bylaws and the SRNB bylaws provide that the presence
in person or by proxy of the holders of a majority of the shares entitled to
vote at any meeting of the shareholders will constitute a quorum for the
transaction of business.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS

         OVERVIEW OF CALIFORNIA LAW. Section 317 of the California General
Corporation Law expressly grants to each California corporation the power to
indemnify its directors, officers and agents against certain liabilities and
expenses incurred in the performance of their duties. Rights to indemnification

                                      -83-
<PAGE>


beyond those provided by Section 317 may be valid to the extent that the rights
are authorized in the corporation's articles of incorporation. Indemnification
may not be made, however, with respect to liability incurred in connection with
any of the following acts for which the liability of directors may not be
limited under the California General Corporation Law: (1) acts or omissions that
involve intentional misconduct or a knowing and culpable violation of law; (2)
acts or omissions that a director believes to be contrary to the best interests
of the corporation or its shareholders or that involve the absence of good faith
on the part of the director; (3) any transaction from which a director derived a
personal benefit; (4) acts or omissions that show a reckless disregard for the
director's duty to the corporation or its shareholders in circumstances in which
the director was aware, or should have been aware, in the ordinary course of
performing a director's duties, of a risk of serious injury to the corporation
or its shareholders; (5) acts or omissions that constitute an unexcused pattern
of inattention that amounts to an abdication of the director's duty to the
corporation or its shareholders; (6) acts or omissions arising out of certain
interested party transactions; or (7) acts in connection with illegal
distributions, loans or guarantees.

         With respect to all proceedings other than shareholder derivative
actions, Section 317 permits a California corporation to indemnify any of its
directors, officers or other agents only if the person acted in good faith and
in a manner the person reasonably believed to be in the best interests of the
corporation and, in the case of a criminal proceeding, had no reasonable cause
to believe the conduct of the person was unlawful. In the case of derivative
actions, a California corporation may indemnify any of its directors, officers
or agents only if the person acted in good faith and in a manner the person
believed to be in the best interests of the corporation and its shareholders.
Furthermore, in derivative actions, no indemnification is permitted (1) with
respect to any matter with respect to which the person to be indemnified has
been held liable to the corporation, unless the indemnification is approved by
the court; (2) of amounts paid in settling or otherwise disposing of a pending
action without court approval; or (3) of expenses incurred in defending a
pending action which is settled or otherwise disposed of without court approval.
To the extent that a director, officer or agent of a corporation has been
successful on the merits in defense of any proceeding for which indemnification
is permitted by Section 317, a corporation is obligated by Section 317 to
indemnify the person against expenses actually and reasonably incurred by him in
connection with the proceeding.

         NVBANCORP. The NVBancorp articles eliminate the liability of its
directors for monetary damages to the fullest extent permissible under
California law and NVBancorp to indemnify its directors, officers and agents
through agreements with the persons, bylaw provisions, vote of shareholders or
disinterested directors, or otherwise, in excess of the indemnification
otherwise permitted by Section 317, subject to applicable statutory prohibitions
upon indemnification.

         The NVBancorp articles and bylaws obligate NVBancorp to indemnify to
the maximum extent permitted by California General Corporation Law its
directors, officers and other agents against liabilities and expenses incurred
in the performance of their duties, subject to the prohibitions of the
California General Corporation Law.

         NVBancorp maintains directors' and officers' liability insurance
policies that indemnify its directors and officers against certain losses in
connection with claims made against them for certain wrongful acts. In addition,
NVBancorp has entered into separate indemnification agreements with its
directors and officers that require NVBancorp, among other things, (1) to
maintain directors' and officers' insurance in reasonable amounts in favor of
those individuals, and (2) to indemnify them against certain liabilities that
may arise by reason of their status or service as agents of NVBancorp to the
fullest extent permitted by California law.

                                      -84-
<PAGE>

         The NVBancorp bylaws and indemnification agreements with its directors
entitle the directors of NVBancorp to be indemnified against liabilities and
reasonable expenses incurred in connection with any claims brought against them
by reason of the fact that they are or were directors and are expressly stated
to be contract rights. NVBancorp directors have been granted the right to be
paid by NVBancorp the expenses incurred in defending the proceedings specified
above in advance of their final disposition, but the directors are required to
undertake to return any amounts advanced to the extent that it is ultimately
determined that they were not legally entitled to be indemnified by NVBancorp in
the proceeding. The directors are also granted the right to bring suit against
NVBancorp to recover unpaid amounts claimed with respect to indemnification and
any expenses incurred in bringing an action. While it is a defense to a suit
that indemnification is prohibited by the California General Corporation Law,
the burden of proving a defense is on NVBancorp.

         The NVBancorp indemnification agreements obligate NVBancorp to
indemnify its directors except under certain circumstances including (1) with
respect to proceedings or claims initiated or brought voluntarily by the
director, except proceedings brought to establish or enforce a right to
indemnification or where the board of directors has approved initiating the
proceedings or claims; (2) expenses or liabilities which have been paid to the
director by an insurance carrier under D&O insurance maintained by NVBancorp;
(3) expenses incurred by the director in a proceeding to enforce or interpret
the indemnification agreement where a court determines that material assertions
made by the director were not made in good faith or were frivolous; (4) where
the indemnification is prohibited by law, Federal Deposit Insurance Corporation
regulations, or the articles of incorporation or bylaws of NVBancorp; (5)
expenses or liabilities incurred by the director under Section 16 of the
Securities Exchange Act of 1934, as amended.

         SRNB. The SRNB articles are substantially similar to the NV Bancorp
articles regarding elimination of the liability of its directors for monetary
damages to the fullest extent permissible under California law and the power of
indemnification in excess of the indemnification otherwise permitted by Section
317, subject to applicable statutory prohibitions upon indemnification and the
restriction that no indemnification is available for expenses, penalties, or
other payments incurred in an administrative proceeding or action instituted by
an appropriate bank regulatory agency, which proceeding or action results in a
final order assessing civil money penalties or requiring affirmative action by
an individual or individuals in the form of payments to SRNB.

         The SRNB bylaws do not include indemnification provisions which are
exclusively covered in the SRNB articles. SRNB also maintains directors' and
officers' liability insurance policies that indemnify its directors and officers
against certain losses in connection with claims made against them for certain
wrongful acts.

         SRNB has entered into indemnity agreements with its directors which
obligate SRNB to pay certain litigation expenses as well as judgments, fines,
penalties and settlements, in the circumstances described below. "Expenses"
includes expenses of proceedings, court costs, attorney's fees and disbursements
and any expenses of establishing a right to indemnification under law or under
the agreement. It does not include judgments, fines, penalties or settlement
amounts paid by or on behalf of SRNB, unless those matters may be indemnified
under the California Corporations Code, federal law and federal banking
regulations. "Proceeding" includes threatened, pending or completed actions,
suits or proceedings, whether brought in the name of SRNB or otherwise, of a
civil, criminal, administrative or investigative nature. It includes proceedings
under the Securities Act of 1933, as amended, the Securities Exchange Act of
1934, as amended, similar state laws and pertinent regulations adopted under
those laws. Proceeding does not include an action brought by a director against
SRNB.

                                      -85-
<PAGE>

         The director's involvement in the proceeding must relate to present or
former service as a SRNB director or as an officer or director of another
enterprise or employee benefit plan at SRNB'S request. Directors are indemnified
against expenses, judgments, fines, penalties, settlements, and other amounts,
actually and reasonably incurred in defending or settling the proceeding. The
director must have acted in good faith and in a manner he or she reasonably
believed to be in the best interests of SRNB. In a criminal proceeding, the
director must also have had no reasonable cause to believe the conduct was
unlawful.

         However, if a director is involved in proceedings brought by or in the
right of SRNB to procure a judgment in its favor, indemnity is limited to
expenses actually and reasonably incurred in connection with defending or
settling the proceeding. Also in that instance, the director must have acted in
good faith in a manner the director believed to be in the best interests of SRNB
and its shareholders and the court must approve the settlement. If a director is
found liable to SRNB, we will indemnify only to the extent that the court
determines that the director is fairly and reasonably entitled to
indemnification for certain expenses.

         To the extent that a director has been successful on the merits in
defending any proceeding or any claim, issue or matter in the proceeding, SRNB
will indemnify against all expenses actually and reasonably incurred.

         SRNB will advance expenses prior to the final disposition of a
proceeding if the director agrees to repay advances to the extent it is
ultimately determined that the director was not entitled to indemnification or,
if required by law, if the director agrees to repay any advances received above
those to which it is ultimately determined the director was entitled. However,
in a proceeding brought by SRNB against the director we are not required to
advance expenses if a majority of the SRNB board of directors, supported by
advice of counsel, believes that the director did not act in good faith in
connection with the subject matter of the proceeding.

         SRNB will also pay a director's expenses in connection with
successfully establishing a right to indemnification or advances. However, if
the director is only partially successful, we will pay only a reasonable and
fair amount of the total expenses unless we are legally prohibited from doing
so.

         If legal action is brought to enforce the agreement, the prevailing
party is entitled to recover actual attorneys' fees and court costs awarded by
the court, in addition to any other amounts to which the prevailing party may be
entitled.

         The indemnity agreement does not preclude any other indemnification
rights the director may have. Except as prohibited by federal law,
indemnification survives the end of the director's term, and may be claimed on
the director's behalf by heirs and personal representatives.

         SRNB does not have to indemnify in connection with any claim:

         (a)      for which the director receives payment under a valid and
                  collectible insurance policy, except for amount the insurer
                  does not pay;

         (b)      for which SRNB is indemnifying the director under another
                  agreement or arrangement;

         (c)      for which the director gained any personal profit or advantage
                  he or she was not legally entitled to;

                                      -86-
<PAGE>


         (d)      where SRNB has the right to demand return of the director's
                  securities trading profits, under Section 16(b) of the
                  Securities Exchange Act of 1934, or similar state laws;

         (e)      brought about or contributed to by the director's active and
                  deliberate dishonesty and dishonest purpose and intent, if
                  there is a final determination that these acts were material
                  to the subject matter of the proceeding;

         (f)      for omissions or acts committed in bad faith or which involve
                  intentional misconduct or a knowing violation of law;

         (g)      for any omission or act that the director believed at the time
                  to be contrary to, or inconsistent with, the best interests of
                  both the Bank and its shareholders; or

         (h)      for any transaction from which the director derived an
                  improper personal economic benefit in a capacity other than as
                  a SRNB shareholder.

         Under the plan of reorganization, from and after the effective date,
NVBancorp will indemnify and hold harmless each present or former officer or
director of SRNB (determined as of the effective time) against all losses,
claims, damages, liabilities, costs, expenses or judgments or amounts that are
paid in the settlement of or in connection with any claim, action, suit,
proceeding or investigation based on or arising out of (1) the fact that the
person is or was a director or officer of SRNB and (2) the plan of
reorganization or the transactions contemplated by the plan of reorganization,
in each case to the full extent permitted by law.

         Additionally, from and after the effective date, NVBancorp will include
in its director and officer insurance policy persons who served as directors and
officers of SRNB or obtain extended coverage under SRNB's director and officer
insurance policy to cover claims made for a period of three years after the
effective date of the merger regarding acts or omissions of SRNB's directors or
officers prior to the effective date of the merger. However, NVBancorp will not
be obligated to make annual premium payments for the insurance to the extent the
premiums exceed 150% of the premiums paid by SRNB for the insurance, as
previously disclosed to NVBancorp. If the premiums for the insurance would at
any time exceed 150% of the premiums paid by SRNB for the insurance, then
NVBancorp will maintain policies of insurance which, in NVBancorp's good faith
determination, provide a maximum coverage available at an annual premium equal
to 150% of the premiums paid by SRNB in respect of the insurance.

         OVERVIEW OF FEDERAL LAW. Federal law authorizes the Federal Deposit
Insurance Corporation to limit, by regulation or order, the payment of
indemnification by insured banks or bank holding companies to their directors
and officers.The Federal Deposit Insurance Corporation has enacted a regulation
that permits the payment of indemnification by banks and bank holding companies
to institution-affiliated directors, officers and other parties only if certain
requirements are satisfied. This regulation permits an institution to make an
indemnification payment to, or for the benefit of, a director, officer or other
party only if the institution's board of directors, in good faith, certifies in
writing that the individual has a substantial likelihood of prevailing on the
merits and that the payment of indemnification will not adversely affect the
institution's safety and soundness. An institution's board of directors is
obligated to cease making or authorizing indemnification payments in the event
that it believes, or reasonably should believe, that the conditions discussed in
the preceding sentence are no longer being met. Further, an institution's board
of directors must provide the Federal Deposit Insurance Corporation and any

                                      -87-
<PAGE>


other appropriate bank regulatory agency with prior written notice of any
authorization of indemnification. In addition, indemnification payments related
to an administrative proceeding or civil action instituted by an appropriate
federal bank regulatory agency are limited to the payment or reimbursement of
reasonable legal or other professional expenses. Finally, the director, officer
or other party must agree in writing to reimburse the institution for any
indemnification payments received should the proceeding result in a final order
being instituted against the individual assessing a civil money penalty,
removing the individual from office, or requiring the individual to cease and
desist from certain institutional activities.

SHAREHOLDER MEETINGS AND ACTION BY WRITTEN CONSENT

         NVBANCORP. The NVBancorp articles authorize shareholder action by
written consent only when first authorized by the board of directors.
Additionally, the NVBancorp bylaws permit a director to be elected at any time
to fill a vacancy on the board of directors that has not been filled by the
directors by the written consent of the holders of a majority of the outstanding
shares entitled to vote for the election of directors.

         SRNB. The SRNB articles authorize shareholder action by written consent
for the purpose of amending SRNB's articles of association.

CUMULATIVE VOTING

                  Cumulative voting allows a shareholder to cast a number of
votes equal to the number of directors to be elected multiplied by the number of
shares held in the shareholder's name on the record date. NVBancorp shareholders
are not entitled to cumulative voting in the election of directors. SRNB
shareholders are entitled to cumulative voting in the election of directors.

AMENDMENT OF ARTICLES AND BYLAWS

         NVBANCORP. The NVBancorp articles and bylaws may be amended or repealed
by the affirmative vote or written consent of a majority of the outstanding
shares entitled to vote.

         The NVBancorp bylaws may be amended or repealed by the affirmative vote
or written consent of a majority of the outstanding shares entitled to vote,
provided that any amendment which reduces (1) the number of directors on a
fixed-number board or (2) the minimum number of directors on a variable-number
board to a number less than five, cannot be adopted if the votes cast or
consents given opposing the action are equal to or more than 16 2/3% of all
outstanding shares entitled to vote.

         Subject to the rights of shareholders to amend the bylaws, the
NVBancorp bylaws provide that the bylaws may be adopted, amended or repealed by
its board of directors, except that only the shareholders can adopt a bylaw or
amendment to the bylaws which (1) specifies or changes the number of directors
on a fixed number board, (2) specifies or changes the minimum or maximum number
of directors on a variable number board or (3) changes from a fixed number board
to a variable number board or vice versa.

         SRNB. Subject to the laws of the United States, SRNB's articles of
association may be amended or repealed by the affirmative vote or written
consent of a majority of the outstanding shares unless the vote of a greater
amount of shares is required by law, and in that case with the vote or written
consent of the greater amount. SRNB's bylaws may be amended, altered or
repealed, at any duly called meeting of the SRNB board of directors by a
majority vote of the total number of directors.

                                      -88-
<PAGE>


FILLING VACANCIES ON THE BOARD OF DIRECTORS

         NVBANCORP. The NVBancorp bylaws provide that vacancies occurring on
their respective boards of directors may be filled by a vote of a majority of
the remaining directors, though less than a quorum, or by a sole remaining
director, except that a vacancy created by the removal of a director may only be
filled by the vote of a majority of the shares entitled to vote represented at a
duly held meeting or by unanimous written consent of the outstanding shares
entitled to vote. The NVBancorp bylaws also provide that the shareholders may
elect a director at any time to fill any vacancy not filled by the directors,
except that any election by written consent, other than to fill a vacancy
created by removal of a director, requires the consent of a majority of the
outstanding shares entitled to vote.

         In addition, the California General Corporation Law provides that if,
after the filling of any vacancy by the directors, the directors then in office
who have been elected by the shareholders constitute less than a majority of the
directors then in office, (1) any holder or holders of an aggregate of 5% or
more of the total number of shares at the time outstanding having the right to
vote for the directors may call a special meeting of shareholders; or (2) the
California Superior Court of the proper county will, upon application of the
shareholder or shareholders, summarily order a special meeting of shareholders,
to be held to elect the entire board of directors.

         SRNB. Any vacancy on the SRNB board of directors for any reason,
including an increase in the number of directors, may be filled by action of the
board of directors. Directors appointed by the SRNB board hold office until
their successors are elected and qualified.

CALL OF ANNUAL OR SPECIAL MEETING OF SHAREHOLDERS AND ACTION BY SHAREHOLDERS
WITHOUT A MEETING

         NVBANCORP. The NVBancorp bylaws provide that a special meeting of the
shareholders may be called at any time by the board of directors, chairman of
the board, president or one or more shareholders holding shares in the aggregate
entitled to cast not less than 10% of the votes at that special meeting. Under
the California General Corporation Law, unless otherwise provided in the
articles of incorporation, any action which may be taken at any annual or
special meeting may be taken without a meeting and without prior notice, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take the action at a meeting at which all
shares entitled to vote thereon were present and voted. The NVBancorp articles
provide that action without a meeting can be taken if the board of directors of
NVBancorp has by resolution first approved any of the action without a meeting.

         SRNB. Any ten or more shareholders owning, in the aggregate, not less
than twenty percent of the outstanding shares of SRNB, may call a special
meeting of the shareholders at any time. Other than amending the articles, no
provision is made in the SRNB articles of association for the shareholders to
take any action in the absence of a duly called meeting.

SHAREHOLDER RIGHTS AGREEMENT

         NVBANCORP. The board of directors of NVBancorp adopted a shareholders
rights agreement on September 9, 1999, under which the board of directors
declared a dividend of one right on each outstanding share of NVBancorp common
stock to shareholders of record as of September 23, 1999. The rights agreement
was not adopted in response to any specific proposal or effort to acquire
control of NVBancorp. Rather, it was adopted to deter abusive takeover tactics
that can be used to deprive shareholders of the full value of their investment.

                                      -89-
<PAGE>

         Under the rights agreement, until it is announced that person or group
has acquired 10% or more of the NVBancorp common stock ("an acquiring person")
or commences a tender offer that will result in that person or group owning 10%
or more of the NVBancorp common stock, the rights will be evidenced by the
NVBancorp common stock certificates, will automatically trade with the NVBancorp
common stock and will not be exercisable. Thereafter, separate rights
certificates will be distributed to each shareholder other than an acquiring
person and each right will entitle its holder to purchase participating
preferred stock having economic value equal to $90.00 for an exercise price of
$45.00. Until exercised, a right confers no voting or other prerogatives of
share ownership.

         Ten days (or on an earlier or later date as determined by the board of
directors) following announcement that any person or group has become an
acquiring person, each right held by a shareholder who is not an acquiring
person or transferee of an acquiring person will entitle its holder to purchase
for the exercise price, a number of shares of NVBancorp common stock or
participating preferred stock having a market value of twice the exercise price.

         In the event an acquiring person controls the board of directors of
NVBancorp and thereafter NVBancorp enters into, consummates or permits to occur
a transaction or series of transactions involving a merger or the sale of more
than 50% of its assets or earning power, and in the case of a merger, where the
acquiring person receives different treatment from other shareholders of
NVBancorp, or the person with whom the merger occurs is the acquiring person or
a person affiliated or associated with the acquiring person, each right will
entitle its holder to purchase a number of shares of common stock of the
acquiring person having a market value of twice the exercise price. If any
person or group acquires between 10% and 50% of the NVBancorp common stock, the
board of directors of NVBancorp may, at its option, exchange one share of
NVBancorp common stock for each right.

         The board of directors may redeem the rights at the price of $0.001 for
each right at any time before a person or group becomes an acquiring person and
prior to the expiration of the rights on September 9, 2009.

agreement which is attached as an exhibit to a current report on Form 8-K dated
September 9, 1999, filed with the Securities and Exchange Commission under the
Securities Exchange Act of 1934, as amended, and incorporated here by this
reference. See "Where You Can Find More Information" on page 97.

         SRNB. The board of directors of SRNB adopted a shareholders rights
agreement on September 30, 1998, under which the board of directors declared a
dividend of one right on each outstanding share of SRNB common stock to
shareholders of record as of October 12, 1998. The rights agreement was not
adopted in response to any specific proposal or effort to acquire control of
SRNB. Rather, it was adopted to deter abusive takeover tactics that can be used
to deprive shareholders of the full value of their investment.

         Under the rights agreement, until it is announced that a person or
group has acquired 10% or more of SRNB's outstanding common stock ("an acquiring
person") or commences a tender offer that will result in ownership of 10% or
more of SRNB's common stock, the rights will be evidenced by the SRNB common
stock certificates, will automatically trade with the SRNB common stock and will
not be exercisable. Thereafter, separate rights certificates will be distributed
to each shareholder other than an acquiring person and each right will entitle
its holder to purchase SNRB common stock at a price of $30.00 per share subject
to certain adjustments. Until exercised, a right confers no voting or other
prerogatives of share ownership.

         Ten days (or on an earlier or later date as determined by the board of
directors) following announcement that any person or group has become an
acquiring person, each right held by a shareholder who is not an acquiring
person or transferee of an acquiring person will entitle its holder to purchase
for the exercise price, a number of shares of SRNB common stock having a market
value of twice the exercise price. This provision also applies if there is a
reclassification of securities or other transaction which increases by more than
1% the proportion share of shares owned by the acquiring person.

         In the event an acquiring person controls the board of directors of
SRNB and thereafter SRNB is involved in a merger or the sale of more than 50% of
its assets or earning power, and in the case of a merger, the acquiring person
receives different treatment from other shareholders of SNRB, or is itself the
acquiror in the merger, each right will entitle its holder to purchase a number
of shares of common stock of the acquiring person having a market value of twice
the exercise price. If any person or group acquires between 10% and 50% of SRNB
common stock, the board of directors of SNRB may, at its option, exchange one
share of SRNB common stock for each right.

         The board of directors may redeem the rights at the price of $0.001 for
each right at any time before a person or group becomes an acquiring person and
prior to the expiration of the rights on October 2, 2002.

CLASSIFIED BOARD PROVISIONS

         NVBANCORP. At present, neither the NVBancorp articles nor the North
Valley Bank bylaws provide for a classified board. Assuming the classified board
proposed contained herein is approved by the shareholders of NVBancorp, the
NVBancorp articles will be amended to provide that, in the event that the
authorized number of directors will be fixed at nine or more, the board of
directors will be divided into three classes: Class I, Class II and Class III,
each consisting of a number of directors equal to as nearly as practicable
one-third the total number of directors. Directors in Class I, Class II and
Class III will initially serve for a term expiring respectively at the 2001,
2002 and 2003 annual meeting of shareholders. Thereafter, each director will
serve for a term ending at the third annual shareholders meeting following the
annual meeting at which the director was elected. In the event that the
authorized number of directors will be fixed with at least six but less than
nine, the board of directors will be divided into two classes, designated as
Class I and Class II, each consisting of one-half of the directors or as close
an approximation as possible. At each annual meeting, each of the successors to
the directors of the class whose term will have expired at such annual meeting
will be elected for a term running until the second annual meeting next
succeeding his or her election and until his or her successor will have been
duly elected and qualified. The number of directors is currently set between six
and 11. The use of a classified board may have the effect of discouraging
takeover attempts.

         SRNB. SRNB's articles do not provide for a classified board of
directors.

         The authorized capital stock of NVBancorp consists of 20,000,000 shares
of NVBancorp common stock, without par value, and 5,000,000 shares of preferred
stock, without par value. As of _____________, 2000, _______________ shares of
NVBancorp common stock and no shares of preferred stock were outstanding and an
additional _______________ shares of the authorized NVBancorp common stock were
available for future grant and reserved for issuance to holders of outstanding
stock options under NVBancorp's stock option plans .

COMMON STOCK

         Holders of NVBancorp common stock are entitled to one vote for each
share held of record on all matters submitted to a vote of shareholders.
Shareholders may not cumulate their votes. Shareholders are entitled to receive
ratably dividends as may be legally declared by NVBancorp's board of directors.
There are legal and regulatory restrictions on the ability of NVBancorp to
declare and pay dividends. See "Market Price and Dividend Information--Dividends
and Dividend Policy" on page ___. In the event of a liquidation, common
shareholders are entitled to share ratably in all assets remaining after payment
of liabilities and liquidation preference for securities with a priority over
the NVBancorp common stock. Shareholders of NVBancorp common stock have no
preemptive or conversion rights. NVBancorp common stock is not subject to calls
or assessments. The transfer agent and registrar for NVBancorp common stock is

PREFERRED STOCK

         The NVBancorp board of directors is authorized to fix the rights,
preferences, privileges and restrictions of the preferred stock and may

If and when any preferred stock is issued, the holders of preferred stock may
have a preference over holders of NVBancorp common stock upon the payment of
dividends, upon liquidation of NVBancorp, in respect of voting rights and in the
redemption of the capital stock of NVBancorp. The issuance of any preferred
stock may have the effect of delaying, deferring or preventing a change in
control of NVBancorp without further action of its shareholders. The issuance of
preferred stock with voting and conversion rights may adversely affect the
voting power of the holders of NVBancorp common stock. NVBancorp has established
a class of preferred stock known as Series A Junior Participating Preferred
Stock, in connection with the adoption of its Shareholder Protection Rights
Agreement. On September 9, 1999, NVBancorp declared a dividend of one right for

purchase from NVBancorp, upon the occurrence of certain events involving a
change in control of NVBancorp, one one-hundredth of a share of the Series A
Junior Participating Preferred Stock.

                     PROPOSAL TO CLASSIFY BOARD OF DIRECTORS

INTRODUCTION

         The terms of the plan of reorganization require that two of the
existing directors of SRNB (to be designated by the board of directors of
NVBancorp) will be appointed to the NVBancorp board of directors promptly after
the consummation of the plan of reorganization and the merger. In addition,
NVBancorp agreed to adopt amendments to the NVBancorp articles of incorporation
and bylaws to divide the board of directors into three classes. If the
amendments are approved by the NVBancorp shareholders, one of the existing
directors of SRNB is to serve as a Class II director and another director of
SRNB is to serve as a Class III director, as discussed below.

         On November 15, 1999, the board of directors adopted amendments to the
NVBancorp articles of incorporation and bylaws which provide that the board of
directors be divided into three classes of directors, each consisting of a
number of directors equal as nearly as practicable to one-third the total number
of directors, for so long as the board consists of at least nine authorized
directors and, in the event that the total number of authorized directors on the
board is at least six but less than nine, for classification of the board of
directors into two classes, each consisting of a number of directors equal as
nearly as practicable to one-half the total number of directors. After initial
implementation at the 2000 annual meeting of shareholders, each class of
directors would be subject to election every third year and would serve for a
three-year term for so long as the board remained classified into three classes,
or would be subject to election every second year and would serve for a two-year
term in the event the board were classified into two classes. Currently, all of
NVBancorp's directors are elected each year to serve a one-year term.

         If the proposal is approved by the shareholders, the board of directors
will, for purposes of initial implementation, designate three classes of
directors for election at the special meeting. Class I will be elected initially
for a one-year term expiring at the 2001 annual meeting of shareholders; Class
II will be elected initially for a two-year term expiring at the 2002 annual
meeting of shareholders; and Class III will be elected for a three-year term
expiring at the annual meeting of shareholders to be held in the year 2003; and,
in each case, until their successors are duly elected and qualified. At each
annual meeting after the 2000 annual meeting, only directors of the class whose
term is expiring would be voted upon, and upon election each director would
serve a three-year term. Commencing with the annual meeting of shareholders
scheduled to occur in 2001, directors elected to Class I would serve for a
three-year term and until their successors are duly elected and qualified,
subject to any decrease in the total number of authorized directors, as
described above. Subsequently in the years 2002 and 2003, directors elected to
Class II and Class III, respectively, would also be elected for a three-year
term and until their successors are duly elected and qualified.

         Classification of the board of directors is permitted by Section 301.5
of the California Corporations Code. Under Section 301.5, a qualifying
California corporation, like NVBancorp, may divide its board of directors into

                                      -93-
<PAGE>


two or three classes, with one-half or one-third of the directors, respectively,
elected at each annual meeting (or as near to one-half or one-third as
practicable). The authorized number of directors must be not less than six in
the case of a two-class board and not less than nine in the case of a
three-class board. Classified boards of directors are permitted under the
corporate law of a majority of states, and NVBancorp believes that well over
one-half of Fortune 500 companies provide for classified boards.

         The text of the proposed amendment to the articles is set forth in
Annex F attached to this joint proxy statement/prospectus. If this proposal is
adopted by the shareholders, in order to make the bylaws consistent with the
amendment to the articles described in this proposal, upon effectiveness of the
filing of the amendment to the articles with the Secretary of State of the State
of California, Section 16 of Article III of the bylaws will be amended to read
as set forth in Annex F, which is incorporated here by this reference.

EFFECT OF CLASSIFICATION OF BOARD

         If adopted, the classification of the board will apply to every
subsequent election of directors for so long as at least six directors are
authorized under the NVBancorp bylaws and the classification provision is not
amended. The NVBancorp bylaws provide that the board of directors will consist
of not less than nine and not more than seventeen directors, with the exact
number of directors currently set at eleven. So long as the board continues to
consist of at least nine authorized directors, after initial implementation of
the classified board, directors will serve for a term of three years rather than
one year, and one-third of the directors (or as near to one-third as
practicable) will be elected each year.

         In the event that the number of directors increases, the increase will
be apportioned by the board among the classes of directors to make each class as
nearly equal in number as possible. If the number of authorized directors is
decreased to at least six but less than nine, the directors will be apportioned
by the board among two classes, each consisting of one-half of the directors or
as close an approximation as possible, directors will serve for a term of two
years, and one-half the directors (or as near to one-half as practicable) will
be elected each year. In any event, a decrease in the number of directors cannot
shorten the term of any incumbent director. Vacancies on the board created by
any resignation, removal or other reason, or by an increase in the size of the
board, may be filled for the remainder of the term by the vote of the majority
of the directors remaining in office or by the vote of holders of a majority of
the outstanding shares of the NVBancorp common stock.

         Under California law, members of the board of directors may be removed
by the board of directors for cause (defined to be a felony conviction or court
declaration of unsound mind), by the shareholders without cause or by court
order for fraudulent or dishonest acts or gross abuse of authority or
discretion. In the case of a board of directors that is not classified, no
director may be removed by the shareholders if the votes cast against the
removal (or, if done by written consent, the votes eligible to be cast by the
non-consenting shareholders) would have been sufficient to elect the director if
voted cumulatively at an election at which the same total number of votes were
cast (or, if the action is taken by written consent, all shares entitled to vote
were voted) and the entire number of directors authorized at the time of the
director's most recent election were then being elected (the "relevant number of
directors"). In the case of classified boards, the relevant number of directors
is (i) the number of directors elected at the most recent annual meeting of
shareholders or, if greater, (ii) the number of directors sought to be removed.
It should be noted that this removal provision applies equally to corporations
that permit cumulative voting and to those that do not.

                                      -94-
<PAGE>


OTHER EFFECTS

         The board of directors believes that the amendment of the articles and
bylaws is in the best interests of NVBancorp and its shareholders.

         Public companies are potentially subject to attempts by various
individuals and entities to acquire significant minority positions in the
company with the intent either of obtaining actual control of the company by
electing their own slate of directors, or of achieving some other goal, such as
the repurchase of their shares by the company at a premium. Public companies
also are potentially subject to inadequately priced or coercive bids for control
through majority share ownership. These prospective acquirors may be in a
position to elect a company's entire board of directors through a proxy contest
or otherwise, even thought they do not own a majority of the company's
outstanding shares at the time. If this proposal is approved, a majority of
NVBancorp's directors could not be removed by those persons until two annual
meetings of shareholders have occurred, unless the removal was for cause and the
requisite vote was obtained. By providing this additional time to the board of
directors and eliminating the possibility of rapid removal of the board, the
directors of NVBancorp will have the necessary time to most effectively satisfy
their responsibility to the NVBancorp shareholders to evaluate any proposal and
to assess and develop alternatives without the pressure created by the threat of
imminent removal. In addition, this proposal, by providing that directors will
serve three-year terms rather than one-year terms, will enhance continuity and
stability in the composition of NVBancorp's board of directors and in the
policies formulated by the board. The board believes that this, in turn, will
permit it more effectively to represent the interests of all shareholders,
including responding to demands or actions by any shareholder or group.
Following adoption of the classified board structure, at any given time at least
one-third of the members of the board of directors will generally have had prior
experience as directors of NVBancorp. The board believes that this will
facilitate long-range planning, strategy and policy and will have a positive
impact on customer and employee loyalty. NVBancorp has not historically had
problems with either the continuity or stability of its board of directors.

         The classification of the board of directors will have the effect of
making it more difficult to replace incumbent directors. So long as the board is
classified into three classes, a minimum of three annual meetings of
shareholders would generally be required to replace the entire board, absent
intervening vacancies. While the proposal is not intended as a
takeover-resistive measure in response to a specific threat, it may discourage
the acquisition of large blocks of NVBancorp's shares by causing it to take
longer for a person or group of persons who acquire a block of shares to effect
a change in management.

         If this proposal is approved and implemented, a shareholder or group of
shareholders seeking to replace a majority of the directors on the board will
generally need to influence the voting of at least a majority of the outstanding
shares at two consecutive annual meetings. In addition, NVBancorp has other
corporate attributes that may also have the effect of helping NVBancorp to
resist an unfriendly acquisition. These include existing provisions in the
NVBancorp articles and bylaws eliminating, subject to certain exceptions, the
liability of directors for monetary damages and eliminating cumulative voting;
provisions in the articles and bylaws providing for indemnification of directors
and officers; and provisions in the bylaws requiring advance notice of
nomination of a candidate for election to the board of directors of NVBancorp
when the nomination is made by a person other than the nominating committee of
the Board.

         This proposal is not in response to any attempt to acquire control of
NVBancorp. However, the board believes that adopting this proposal is prudent,
advantageous and in the best interests of shareholders because it will give the
board more time to fulfill its responsibilities to shareholders, and it will

                                      -95-
<PAGE>


provide greater assurance of continuity and stability in the composition and
policies of the board of directors. The board also believes the advantages
outweigh any disadvantage relating to discouraging potential acquirors from
attempting to obtain control of NVBancorp.

REQUIRED APPROVAL

         Approval of the proposed amendment to the articles and the bylaws
requires the affirmative vote of the holders of a majority of the outstanding
shares of NVBancorp's common stock. If this proposal is not approved, it is the
intention of NVBancorp and SRNB that the two existing directors of SRNB (to be
designated by the board of directors of NVBancorp) will be appointed to the
NVBancorp board of directors to serve along with the existing NVBancorp
directors, without classification as contemplated by this proposal.

RECOMMENDATION OF MANAGEMENT

         The board of directors believes that the advantages of the proposed
amendments to the articles and bylaws classifying the board of directors for
purposes of the election of directors greatly outweigh the possible
disadvantages of the amendments. Accordingly, the board of directors has
unanimously approved the proposed amendments and unanimously recommends that the
shareholders vote "FOR" their approval.

         Each of NVBancorp and SRNB will bear the cost of the solicitation of
proxies from their respective shareholders. In addition to solicitation by mail,
the directors, officers and employees of NVBancorp or SRNB may solicit proxies
from their respective shareholders by telephone or telegram or in person. Those
persons will not be additionally compensated, but will be reimbursed for
reasonable out-of-pocket expenses incurred in connection with the solicitations.
Arrangements will also be made with brokerage firms, nominees, fiduciaries and
other custodians, for the forwarding of solicitation materials to the beneficial

owners of shares held of record by those persons, and NVBancorp or SRNB, as
applicable, will reimburse those persons for their reasonable out-of-pocket
expenses in connection with those solicitations. SRNB has retained Skinner & Co.
of San Francisco, California, to aid in the solicitation of proxies and to
verify certain records related to the solicitations. Skinner & Co. will receive
$5,000 as compensation for its services and $5,000 as reimbursement for its
related out-of-pocket expenses. NVBancorp does not intend to retain a proxy
solicitor.

                            AGREEMENT
                               AND
                PLAN OF REORGANIZATION AND MERGER


     THIS  AGREEMENT AND PLAN OF REORGANIZATION AND MERGER, dated
as of October 3, 1999, ("Agreement"), is made and entered into by
and   among   North  Valley  Bancorp,  a  California  corporation
("NVBancorp"),  NVB  Interim National Bank, an  interim  national
banking  association to be formed at the direction  of  NVBancorp
("Interim Bank") and Six Rivers National Bank, a national banking
association ("SRNB").


                           Recitals:

     A.   The  Boards of Directors of NVBancorp and SRNB deem  it
          advisable  and  in the best interests of NVBancorp  and
          SRNB,   and   their   respective   shareholders,   that
          NVBancorp, Interim Bank and SRNB enter into a  business
          combination,  with the expectation that  the  resulting
          multi-bank  holding company structure will combine  the
          best  elements  of  NVBancorp,  North  Valley  Bank,  a
          California  state-chartered  banking  corporation   and
          currently  the  wholly  owned subsidiary  of  NVBancorp
          ("NVB"),  and  SRNB.  Pursuant to a forward  triangular
          merger  under  the  authority of 12 U.S.C.  215a,  SRNB
          shall  merge with and into Interim Bank (the  "Merger")
          and  the  resulting national banking  association  will
          continue with the national bank charter number of  SRNB
          and  the  name "Six Rivers National Bank" as a  wholly-
          owned subsidiary of NVBancorp.

     B.   Upon organization of the Interim Bank, the Interim Bank
          will  become a party to this Agreement by the execution
          and  delivery of an addendum to this Agreement, in form
          and  substance acceptable to NVBancorp,  SRNB  and  the
          directors and shareholders of the Interim Bank.

     C.   This Agreement and the Merger Agreement,  substantially
          in the form  attached  hereto as Exhibit A and intended
          to be filed with the Office of the  Comptroller  of the
          Currency (the "Merger  Agreement"),  have been approved
          by the Boards of Directors of NVBancorp  and SRNB,  and
          will be approved by the directors and  shareholders  of
          the Interim Bank, and the principal terms of the Merger
          will be submitted for approval of the  shareholders  of
          NVBancorp  and  SRNB  at  special   meetings  of  their
          respective shareholders.

     D.   The  Merger  is  intended  to  qualify  as  a  tax-free
          reorganization within the meaning of Section 368 of the
          Internal Revenue Code of 1986, as amended (the  "IRC"),
          and the Merger shall be accounted for as a "pooling  of
          interests."

     E.   Pursuant  to  the  Merger, each SRNB  shareholder  will
          receive,  in  exchange for each share  of  SRNB  common
          stock  ("SRNB Share" or "SRNB Shares"), the  number  of
          shares of NVBancorp common stock ("NVBancorp Share"  or
          "NVBancorp Shares") determined in accordance  with  the
          conversion  ratio  as  more fully  set  forth  in  this
          Agreement  and in the Merger Agreement (the "Conversion
          Ratio").

     F.   The Boards of Directors of NVBancorp, NVB and SRNB have
          determined  that the Merger and the other  transactions
          contemplated by this Agreement are consistent with, and
          will contribute to the furtherance of, their respective
          business strategies and goals.


     NOW,  THEREFORE,  in consideration of the premises  and  the
mutual  agreements contained herein and in the Merger  Agreement,
the parties hereto agree as follows:

1.   THE MERGER.

     1.1.  Effective  Date and Time.  Subject to  the  terms  and
conditions of this Agreement, the  Merger shall become  effective
on  the date ("Effective Date") and at the time ("Effective  Time
of the Merger") selected by the parties after the Merger has been
certified  by  the  Office  of the Comptroller  of  the  Currency
("OCC"), an executed copy of the Merger Agreement has been  filed
with  and accepted by the OCC, all Government Approvals have been
received   and satisfied and all other conditions to  the  Merger
set forth in this Agreement have been satisfied.

     1.2.  Effect  of  the  Merger.  Subject  to  the  terms  and
conditions  of  this  Agreement, at the  Effective  Time  of  the
Merger,  SRNB shall be merged with and into the Interim Bank  and
the  resulting  national banking association in the  Merger  (the
"Resulting  Bank") will continue as a wholly-owned subsidiary  of
NVBancorp with the national bank charter number of SRNB  and  the
name "Six Rivers National Bank."  All assets, rights, privileges,
immunities, powers, franchises and interests of SRNB  in  and  to
every type of property (real, personal and mixed) and chooses  in
action,  as  they  exist  as  of the  Effective  Date,  including
appointments, designations and nominations and all  other  rights
and  interests as trustee, executor, administrator, registrar  of
stocks  and bonds, guardian of estate, assignee, receiver and  in
every other fiduciary capacity, shall pass and be transferred  to
and  vest  in the Resulting Bank by virtue of the Merger  at  the
Effective  Time  of  the Merger without any deed,  conveyance  or
other transfer; the separate corporate existence of SRNB and  the
Interim Bank shall cease; and the Resulting Bank shall be  deemed
to  be  the same entity as each of SRNB and the Interim Bank  and
shall  be subject to all of their duties and liabilities of every
kind  and  description.  The Resulting Bank shall be  responsible
and  liable  for all the liabilities and obligations of  each  of
SRNB  and  the Interim Bank; and any claim existing or action  or
proceeding pending by or against SRNB or the Interim Bank may  be
prosecuted as if the Merger had not taken place, or the Resulting
Bank may be substituted in the place of SRNB or the Interim Bank.
Neither  the rights of creditors nor any liens upon the  property
of either SRNB or the Interim Bank shall be impaired by reason of
the Merger.

2.   CONVERSION AND CANCELLATION OF SHARES.

     2.1.  Conversion of SRNB Shares.  At the effective  time  of
the Merger, by virtue of the Merger and without any action on the
part of NVBancorp, SRNB or any holder of SRNB Shares, subject  to
Section  3.1.g. hereof, each outstanding SRNB Share  (other  than
any shares as to which dissenters' rights have been perfected  as
provided  in  Section 2.7 hereof), shall be  converted  into  the
right  to  receive  a  number of NVBancorp  Shares  (or  fraction
thereof,  subject to Section 2.2 hereof) based  on  a  conversion
ratio (the "Conversion Ratio") determined as follows:

          a.   If  the  Average Closing Price is  not  less  than
               $10.00 and is not more than $12.06, the Conversion
               Ratio shall be 1.450.

          b.   If  the  Average Closing Price is  not  less  than
               $12.07 and is not more than $12.50, the Conversion
               Ratio  shall be determined by dividing  $17.50  by
               the Average Closing Price.

          c.   If  the  Average Closing Price is more than $12.50
               but  is not more than $15.00, the Conversion Ratio
               shall be 1.400.

          d.   If  the Average Closing Price is less than $10.00,
               the  provisions of Section 12.b.(xvi) hereof shall
               be applicable.

          e.   If  the  Average  Closing Price  is  greater  than
               $15.00,  the Conversion Ratio shall be  determined
               in accordance with the following formula:

  Conversion  Ratio = $21.00 + 0.56 x (Average Closing Price minus $15.00)
                              Average Closing Price

          f.   In addition to sub-paragraphs a. through e. above,
               if  the  shareholders' equity of SRNB  as  of  the
               Determination Date is less than $19,000,000,  then
               NVBancorp  and SRNB shall re-calculate and  modify
               the  Conversion  Ratio by reducing the  Conversion
               Ratio determined in accordance with sub-paragraphs
               a.  through  e.  above by 0.0P10  for  each  whole
               $100,000 amount of shortfall then existing in  the
               shareholders' equity of SRNB.  For example, if the
               Average   Closing   Price  is  $12.50,   but   the
               shareholders' equity of SRNB is $18,899,000,  then
               the  Conversion  Ratio shall be  1.390.   As  used
               herein,  "shareholders' equity of SRNB"  shall  be
               the  sum  of the following components as reflected
               on  the books of SRNB: (i) common stock par value,
               plus  (ii) additional paid in capital, plus  (iii)
               retained earnings (or accumulated deficit), which,
               as of June 30, 1999, was $19,151,000.

As  used herein, "Average Closing Price" means the average of the
daily  average of bid and ask prices of NVBancorp Shares  on  the
Nasdaq  National  Market for the twenty (20) consecutive  trading
(business) days ending at the end of the third trading (business)
day  immediately  preceding the Effective  Time  of  the  Merger,
rounded to four decimal places (whether or not trades occurred on
those  days).   The third business day prior to the date  of  the
Proposed  Closing  Date, as defined in Section  9.a.  hereof,  is
hereinafter called the "Determination Date."

     2.2  Fractional Shares.  Notwithstanding any other provision
hereof, no fractional shares of NVBancorp Shares shall be  issued
to  holders  of SRNB Shares.  In lieu thereof, each  such  holder
entitled to a fraction of a NVBancorp Share shall receive, at the
time of surrender of the certificate or certificates representing
such  holder's SRNB Shares, an amount in cash equal to the market
value  per share of the NVBancorp Shares, being the closing price
of  NVBancorp Shares on the Nasdaq National Market on the trading
(business)  day immediately preceding the Effective Time  of  the
Merger,   multiplied  by the fraction of an  NVBancorp  Share  to
which  such  holder otherwise would be entitled.  No such  holder
shall  be entitled to dividends, voting rights, interest  on  the
value of, or any other rights in respect of a fractional share.

     2.3  Surrender of SRNB Shares.

          a.    Prior  to  the  Effective Date,  NVBancorp  shall
appoint   ChaseMellon  Shareholder  Services,  L.L.C.,   or   its
successor, or any other bank or trust company (having capital  of
at  least $50 million) mutually acceptable to NVBancorp and SRNB,
as  exchange  agent  (the "Exchange Agent") for  the  purpose  of
exchanging certificates representing SRNB Shares and at and after
the  Effective  Time  of the Merger, NVBancorp  shall  issue  and
deliver  to  the  Exchange  Agent  such  number  of  certificates
representing NVBancorp Shares and cash for payment of  fractional
shares,  as shall be required to be delivered to holders of  SRNB
Shares pursuant to Article 2 of the Merger Agreement.  As soon as
practicable  after the Effective Time of the Merger, each  holder
of  SRNB Shares converted pursuant to Section 2.1, upon surrender
to  the Exchange Agent of one or more certificates for such  SRNB
Shares   for  cancellation,  will  be  entitled  to   receive   a
certificate or certificates representing the number of  NVBancorp
Shares determined in accordance with Section 2.1 and a payment in
cash  with  respect to fractional shares, if any,  determined  in
accordance with Section 2.2.

          b.    No  dividends or other distributions of any  kind
which  are  declared payable to shareholders  of  record  of  the
NVBancorp Shares after the Effective Date will be paid to persons
entitled to receive such certificates for NVBancorp Shares  until
such  persons  surrender  their  certificates  representing  SRNB
Shares.   Upon  surrender of such certificates representing  SRNB
Shares,  the holder thereof shall be paid, without interest,  any
dividends  or  other distributions with respect to the  NVBancorp
Shares  as to which the record date and payment date occurred  on
or  after  the  Effective  Date and on  or  before  the  date  of
surrender.

          c.    If any certificate for NVBancorp Shares is to  be
issued  in  a  name other than that in which the certificate  for
SRNB  Shares surrendered in exchange therefor is registered,  any
transfer  costs or expenses (except taxes) required by reason  of
the  issuance of certificates for such NVBancorp Shares in a name
other  than  the registered holder of the certificate surrendered
shall be paid by the person requesting such change.

          d.    All dividends or  distributions,  and any cash to
be paid pursuant to Section 2.2 in lieu of fractional  shares, if
held by the Exchange Agent for payment or delivery to the holders
of  unsurrendered   certificates  representing  SRNB  Shares  and
unclaimed at the end of one year from the Effective Date, shall

                                -4-
<PAGE>

(together with any interest earned thereon) at such time be  paid
or redelivered by the Exchange Agent to NVBancorp, and after such
time any holder of a certificate representing SRNB Shares who has
not  surrendered  such certificate to the Exchange  Agent  shall,
subject  to applicable law, look, as a general creditor, only  to
NVBancorp   for  payment  or  delivery  of  such   dividends   or
distributions or cash, as the case may be.

     2.4  Further Transfers of SRNB Shares. At the Effective Time
of the Merger,  the stock  transfer books of SRNB shall be closed
and no  transfer  of SRNB Shares  theretofore  outstanding  shall
thereafter be made.

     2.5. Adjustments. If, between the date of this Agreement and
the Effective Date, the outstanding shares of NVBancorp Shares or
SRNB Shares shall have been  changed  into a different  number of
shares or a  different  class by reason of any  reclassification,
recapitalization,  split-up,  combination,  exchange of shares or
readjustment,  or a stock dividend thereon shall be declared with
a record date within such period,  the number of NVBancorp Shares
to be issued and  delivered  in the Merger in  exchange  for each
outstanding SRNB Share shall be correspondingly adjusted.

     2.6  Treatment of Stock Options.

          a.    Each  person  holding  one  or  more  options  to
purchase  SRNB Shares ("SRNB Option" or "SRNB Options")  pursuant
to  the Six Rivers National Bank Stock Option Plan, as amended to
date  ("SRNB Stock Option Plan") shall have the right, in his  or
her discretion, to either:

               (i)   exercise any vested  portion  (including any
          portion  vested as a result of the  Merger) of the SRNB
          Option to acquire  SRNB Shares  prior to the  Effective
          Date; or

               (ii)  as  of  the  Effective Time of  the  Merger,
          surrender  the  SRNB Option agreement to NVBancorp,  in
          which  event such person will be entitled to receive  a
          substitute option ("Substitute Option") exercisable for
          (a)  the number of NVBancorp Shares equal to the number
          of  SRNB Shares for which such person held SRNB Options
          multiplied by the Conversion Ratio and rounded down  to
          the nearest whole share, and (b) the exercise price for
          the shares subject to the SRNB Option shall be adjusted
          by  dividing the pre-Merger exercise price for the SRNB
          Option  by the Conversion Ratio, rounded to the nearest
          penny.

          b.    The Substitute Options to be received in exchange
for  SRNB  Options shall be, to the greatest extent  practicable,
vested  to  the  same extent as before the Merger (including  any
portion vested as a result of the Merger), shall continue to vest
on  the  same  vesting schedule as provided  under  the  original
applicable  SRNB  Option  agreement,  shall  be  exercisable   as
provided  in  the original applicable SRNB Option  agreement  and
shall   otherwise   preserve  the  characteristics,   terms   and
conditions  of  the original SRNB Option to the  greatest  extent
possible,  subject to the requirements of law and any  applicable
rules and regulations of the OCC.

                                -5-

     2.7  Dissenting  Shareholders.   Any  SRNB  Shares  held  by
persons who have satisfied the requirements of 12 U.S.C.  215a(b)
("Section 215a(b)") with respect to such SRNB Shares shall not be
converted  pursuant to this  Agreement,  but the holders  thereof
shall be  entitled  only to such  rights as are  granted  them by
Section 215a(b).  Each dissenting  shareholder who is entitled to
payment of his or her SRNB  Shares  pursuant  to Section  215a(b)
shall receive  payment from  NVBancorp in an amount as determined
pursuant to Section 215a(b).

     2.8  NVB Interim National Bank as Party.  NVBancorp and SRNB
agree  that, when organized and chartered by the OCC, the Interim
Bank shall become a party to this Agreement by the execution  and
delivery  of an addendum to the Agreement, in form and  substance
acceptable  to NVBancorp, SRNB and the directors and shareholders
of the Interim Bank.

3.   COVENANTS OF THE PARTIES.

     3.1. Covenants of NVBancorp. During the period from the date
of this Agreement and continuing  until the Effective Time of the
Merger,  except as  expressly  contemplated  or permitted by this
Agreement or to the extent that SRNB shall  otherwise  consent in

Effective  Time  of  the  Merger, a registration  statement  with
respect  to  the options to be granted and shares  to  be  issued

Agreement.

          d.     Reservation,   Issuance  and   Registration   of

connection  with the Merger and in accordance with the  terms  of
this  Agreement  (i) a number of NVBancorp Shares  sufficient  to

of  Section  2.1 above and (ii) the maximum number  of  NVBancorp
Shares to which the holders of Substitute Options may be entitled
pursuant to Section 2.6 above at or after the Effective  Time  of
the  Merger.  NVBancorp shall cause such NVBancorp Shares  to  be
registered under the 1933 Act, as provided in Section 6 below.

          e.     Nasdaq Stock  Market  Listing.  NVBancorp  shall
take all  necessary  action to list  NVBancorp's  Shares with the

          f.    Director and Officer Liability.  In the event  of
any  threatened  or  actual claim, action,  suit,  proceeding  or
investigation,   whether  civil,  criminal   or   administrative,
including,  without  limitation, any such  claim,  action,  suit,
proceeding  or investigation in which any person who is  now,  or
has  been at any time prior to the date of this Agreement, or who
becomes  prior  to the Effective Time, a director or  officer  of
SRNB  ("Indemnified Parties") is, or is threatened to be, made  a
party  based  in whole or in part on, or arising in whole  or  in
part  out of, or pertaining to (i) the fact that he is or  was  a
director  or  officer  of SRNB or any predecessor  or  (ii)  this
Agreement or any of the transactions contemplated hereby, whether
in  any  case  asserted or arising before or after the  Effective
Date,  NVBancorp and SRNB agree to cooperate and use  their  best
efforts  to defend against and respond thereto.  It is understood
and  agreed  that  after  the  Effective  Date,  NVBancorp  shall
indemnify  and  hold  harmless, as  and  to  the  fullest  extent
permitted by law, each such Indemnified Party against any losses,
claims,   damages,   liabilities,  costs,   expenses   (including
reasonable attorney's fees and expenses in advance of  the  final
disposition  of  any claim, suit, proceeding or investigation  to
each  Indemnified  Party to the fullest extent permitted  by  law
upon  receipt  of  any undertaking required by  applicable  law),
judgments,  fines  and amounts paid in settlement  in  connection
with   any  such  threatened  or  actual  claim,  action,   suit,
proceeding  or  investigation  and  in  the  event  of  any  such
threatened   or  actual  claim,  action,  suit,  proceeding,   or
investigation (whether asserted or arising before  or  after  the
Effective  Date),  the  Indemnified Parties  may  retain  counsel
reasonably   satisfactory   to  them  after   consultation   with
NVBancorp; provided, however, that (1) NVBancorp shall  have  the
right  to  assume  the defense thereof and upon  such  assumption
NVBancorp  shall not be liable to any Indemnified Party  for  any

                               -7-
<PAGE>

legal   expenses   of  other  counsel  or  any   other   expenses
subsequently incurred by any Indemnified Party in connection with
the  defense  thereof,  except that if NVBancorp  elects  not  to
assume  such  defense  or  counsel for  the  Indemnified  Parties
reasonably advises the Indemnified Parties that there are  issues
which  raise  conflicts  of interest between  NVBancorp  and  the
Indemnified  Parties, the Indemnified Parties may retain  counsel
reasonably   satisfactory   to  them  after   consultation   with
NVBancorp,  and  NVBancorp  shall pay  the  reasonable  fees  and
expenses  of  such  counsel  for  the  Indemnified  Parties,  (2)
NVBancorp  shall be obligated pursuant to this paragraph  to  pay
for  only one firm of counsel for all Indemnified Parties, unless
an  Indemnified Party shall have reasonably concluded;  based  on
the   advice   of  counsel,  that  in  order  to  be   adequately
represented,  separate counsel is necessary for such  Indemnified
Party,  in  which case, NVBancorp shall be obligated to  pay  for
such separate counsel, (3) NVBancorp shall not be liable for  any
settlement  effected  without its prior  written  consent  (which
consent  shall  not be unreasonably withheld), and (4)  NVBancorp
shall have no obligation hereunder to any Indemnified Party  when
and  if  a  court  of  competent  jurisdiction  shall  ultimately
determine,  and  such determination shall have become  final  and
nonappealable, that indemnification of such Indemnified Party  in
the  manner contemplated hereby is prohibited by applicable  law;
provided, further, that NVBancorp hereby expressly undertakes the
indemnification  of  certain officers and  directors  and  former
officers   and   directors   in  existing   matters   for   which
indemnification  is  being provided by SRNB and,  notwithstanding
the provisions of this Section 3.1.f., such indemnification shall
be on the same terms and subject to the same limitations as shall
exist  on  the Effective Date.  Any Indemnified Party wishing  to
claim Indemnification under this Section 3.1.f., upon learning of
any  such claim, action, suit, proceeding or investigation, shall
notify  NVBancorp thereof, provided that the failure to so notify
shall  not  affect  the  obligations  of  NVBancorp  under   this
Section  3.1.f.  except  to the extent  such  failure  to  notify
materially  prejudices NVBancorp.  NVBancorp's obligations  under
this  Section  3.1.f. continue in full force  and  effect  for  a
period  of  four  (4)  years from the Effective  Date;  provided,
however,  that  all rights to indemnification in respect  of  any
claim  ("Claim")  asserted  or  made  within  such  period  shall
continue  until the final disposition of such Claim and  provided
further that NVBancorp shall have the right of setoff against any
payments required to be made by NVBancorp to an Indemnified Party
pursuant  to  this  Section  3.1.f.  to  the  extent  that   such
Indemnified  Party  shall have received  the  indemnification  to
which such Indemnified Party is entitled from an insurer under  a
directors' and officers' liability insurance policy maintained by
SRNB or NVBancorp.

           NVBancorp,  from  and after the Effective  Date,  will
directly  or indirectly cause the persons who served as directors
or officers of SRNB on or before the Effective Date to be covered
by   NVBancorp's  existing  directors'  and  officers'  liability
insurance policy (provided that NVBancorp may substitute therefor
policies  of  at  least the same coverage and amounts  containing
terms  and  conditions which are not less advantageous than  such
policy)  or  so-called tail coverage obtained in connection  with
SRNB's  directors' and officers' liability insurance policies  in
effect  as  of the Effective Date; provided that NVBancorp  shall

                               -8-
<PAGE>

not  be  obligated  to  make  annual premium  payments  for  such
insurance to the extent such premiums exceed 150% of the premiums
paid  as  of the date hereof by SRNB for such insurance.  Subject
to   the  preceding  sentence,  such  insurance  coverage,  shall
commence on the Effective Date and will be provided for a  period
of  no less than three (3) years after the Effective Date.   From
the  date  hereof through the Effective Date and subject  to  the
foregoing,  SRNB shall use its best efforts to arrange  for  tail
coverage  related to its then current policies of directors'  and
officers' liability insurance and, following the Effective  Date,
NVBancorp  shall exercise those rights which it may  have  to  in
order  to commence such coverage.  In connection with any active,
pending  claim  under an existing SRNB directors'  and  officers'
liability  insurance policy, NVBancorp will take no  action  that
would have the effect of waiving any such claim and will not omit
to take any action that is necessary to preserve such a claim.

           In  the  event  NVBancorp or any of its successors  or
assigns (A) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of
such consolidation or merger, or (B) transfers or conveys all  or
substantially  all of its properties and assets  to  any  person,
then,  and  in  each  such case, to the extent necessary,  proper
provision  shall be made so that the successors  and  assigns  of
NVBancorp assume the obligations set forth in this Section 3.1.f.
The  provisions of this Section 3.1.f. are intended to be for the
benefit  of, and shall be enforceable by, each Indemnified  Party
and his or her heirs and representatives.

          g.     Business   Combination.   NVBancorp   shall  not
solicit  or accept  any offer from any third  party  regarding  a
Business  Combination  (as  defined in Section  3.2.i.  below) of
NVBancorp  or NVB with any  other  entity  unless  such  offer is
expressly  conditioned  upon the  performance by NVBancorp or the
successor  in  interest  of  NVBancorp's  obligations  under this
Agreement.  In the  event  of such a  Business  Combination,  the
Conversion Ratio shall be 1.400.

     3.2. Covenants of SRNB.  During the period from the date  of
this  Agreement and continuing until the Effective  Time  of  the
Merger,  except  as expressly contemplated or permitted  by  this
Agreement or to the extent that NVBancorp shall otherwise consent
in  writing,  which consent will not be unreasonably withheld  or
delayed  more than three (3) business days after the request  for
consent is delivered:

          a.     Termination  of SRNB  Stock  Option  Plan.  SRNB
shall take all necessary  action to cause the  termination of the
SRNB Stock  Option Plan at the  Effective  Time of the Merger and
the exercise or surrender (in exchange for Substitute Options) of
SRNB Options outstanding thereunder.

          b.     Termination or Merger of SRNB Benefit Plans.  If
requested by NVBancorp and subject to the mutual agreement of the
parties,  SRNB  shall  take all  necessary  action  to cause  the
termination  or merger of SRNB  Employee  Plans  (as  defined  in
Section 4.n. hereof) at the Effective Time of the Merger.

                               -9-
<PAGE>

          c.     Capital Commitments and Expenditures.  After the
execution of this Agreement,  no new capital commitments shall be
entered into, and no capital  expenditures  shall be made by SRNB
in excess of Fifty Thousand  Dollars  ($50,000) in the aggregate,
including  but not limited to,  creation of any new  branches and
acquisitions  or leases of real property,  except  commitments or
expenditures   within  existing  operating  and  capital  budgets
heretofore furnished to and approved in writing by NVBancorp.

          d.     Compensation. SRNB shall not make or approve any
increase in the  compensation  payable or to become payable by it
to any of its  directors,  officers,  employees  or  agents  with
annual  salaries  in  excess  of  Seventy-five  Thousand  Dollars
($75,000)  (including but not limited to compensation through any
profit  sharing,  pension,  retirement,  severance,  incentive or
other  employee   benefit  program  or  arrangement   other  than
compensation  related to a SRNB  Employee  Stock  Ownership  Plan
contribution  for  1999  which  is  consistent  with  the  amount
contributed  for  1998),  nor  shall  any  bonus  payment  or any
agreement  or  commitment  to make a bonus  payment be made,  nor
shall any stock option, warrant or other right to acquire capital
stock  be  granted  (except  as  provided  in  Section  2.6),  or
employment  agreement  (other than any such employment  agreement
that may  arise by  operation  of law upon the  hiring of any new
employee)  or  consulting  agreement be entered into by SRNB with
any  such  directors,   officers,   employees  or  agents  unless
NVBancorp has given its prior  written  consent.  Nothing  herein
shall  prevent the payment to officers  and  employees of SRNB of
regular  salary  increases,  consistent  with past  practices  in
connection with regular salary reviews or bonuses consistent with
past practices, as heretofore disclosed by SRNB to NVBancorp.

          e.     Loans.  SRNB shall  not,  without  first  having
obtained the written consent of NVBancorp  (which shall be deemed
to have been given if no response is provided  following  written
request  therefor  within three (3)  business  days of receipt of
such request),  cause, allow, or suffer its officers or agents to
commit  to any  loan or  renewal  which  does not  comply  in all
material  respects  with its  credit  policies  in effect  and as
disclosed  and  provided to  NVBancorp  prior to the date of this
Agreement, provided, however, that all new stand-alone extensions
of credit over Two Hundred  Thousand Dollars  ($200,000),  except
for  conforming  FHLMC and FNMA  loans,  shall be subject to such
prior written  consent.  The prior  written  consent of NVBancorp
shall be  deemed  waived  for any new  stand-alone  extension  of
credit which is below Two Hundred Thousand Dollars ($200,000) and
where  such new  stand-alone  extension  of  credit  is either in
compliance with SRNB credit policy and the approving  officer has
the  requisite  lending  authority or has (have) been approved by
the SRNB loan committee or equivalent committee of the SRNB Board
of  Directors  performing  such  function.  SRNB  shall  promptly
provide  to  NVBancorp  for  its  review  and  comment   relevant
information  concerning any proposed new stand-alone extension of
credit in excess of One Hundred Thousand Dollars ($100,000).

          f.     Certain  Notices.  SRNB shall  notify  NVBancorp
promptly  (but not less  often than  weekly) in writing  upon the
occurrence of any of the following:

                               -10-
<PAGE>

               (i)   the  classification of  any  loan  as  "Non-
          Accrual,"  "Watch," "Other Assets Specially Mentioned,"
          "Substandard," "Doubtful" or "Loss"; or

               (ii)  the  filing  or commencement  of  any  legal
          action  or  other  proceeding or investigation  against
          SRNB.

          g.    Loan Review.  Until the Effective Date, SRNB will
submit  to  NVBancorp  upon  request (but  not  less  often  than
monthly) a list of loans that may reasonably be described  as  or
are   included   in   any   of   the  following   categories   or
specifications:  (i) any new stand-alone extension of credit over
One  Hundred  Thousand Dollars ($100,000), (ii) any  restructured
loan  as  defined under SFAS 15, regardless of amount, (iii)  any
renewal or upgrade or other change in status of an existing  loan
over Fifty Thousand Dollars ($50,000), and (iv) any renewal of an
existing  loan  previously classified by management  or  internal
policy  or  procedure of SRNB, or by any outside review examiner,
accountant  or  any  bank regulatory authority as  "Non-Accrual,"
"Watch,"   "Other  Assets  Specially  Mentioned,"  "Substandard,"
"Doubtful,"  or "Loss," or classified using categories  or  words
with  similar  import,  in a commitment amount  over  Twenty-five
Thousand  Dollars ($25,000) or where the aggregate  debt  of  the
borrower and its affiliates and/or related interests will  exceed
Twenty-five  Thousand Dollars ($25,000).  SRNB  will  provide  to
NVBancorp  a  copy  of  the  loan  approval/credit  write-up  and
supporting information on any loan described in subsections  (i),
(ii), (iii) or (iv) above at the time of delivery of such list of
loans.   Copies of such supporting information shall be  returned
to SRNB within seven (7) days of receipt.

          h.    Loan  Provision.   SRNB shall  maintain  adequate
reserves for loan losses.  Without limiting the generality of the
foregoing,  each  month  following the  date  of  this  Agreement
through the Effective Date, SRNB shall expense as a provision  to
its allowance for loan losses, such amount as may be required  by
the  written loan loss policy and procedures adopted by the Board
of  Directors of SRNB and provided to NVBancorp prior to the date
of this Agreement.

          i.   No Merger or Solicitation.

               (i)   Subject to the continuing fiduciary duty  of
          the  Board  of  Directors of SRNB to its  shareholders,
          prior  to the Effective Time of the Merger, SRNB  shall
          not  effect  or  agree  to  effect  or  enter  into   a
          transaction or series of transactions with one or  more
          third  persons,  groups or entities providing  for  the
          acquisition of all or a substantial part of SRNB or its
          subsidiaries,  whether by way of  merger,  exchange  of
          stock,   sale   of  assets,  or  otherwise   ("Business
          Combination"), acquire or agree to acquire any  of  its
          own capital stock or the capital stock or asset (except
          in  a  fiduciary capacity or in the Ordinary Course  of
          Business)   of  any  other  entity,  or  commence   any
          proceedings  for  winding up and dissolution  affecting
          either of them.

                               -11-
<PAGE>

               (ii)   Subject to the continuing fiduciary duty of
          the  Board of  Directors  of SRNB to its  shareholders,
          prior to the Effective Time of the Merger, neither SRNB
          nor any of its officers,  directors or affiliates,  nor
          any investment  banker,  attorney,  accountant or other
          agent, advisor or representative retained by SRNB shall
          (a) solicit or encourage,  directly or indirectly,  any
          inquiries,  discussions  or  proposals  for,  continue,
          propose  or  enter  into  discussions  or  negotiations
          looking   toward,   or  enter  into  any  agreement  or
          understanding  providing for, any Business  Combination
          with any third  party;  or (b)  disclose,  directly  or
          indirectly,    any   nonpublic   information   to   any
          corporation,  partnership,  person  or other  entity or
          group  concerning  SRNB's  business and  properties  or
          afford any such other party  access to its  properties,
          books or records or otherwise  assist or encourage  any
          such other party in connection  with the foregoing,  or
          (c) furnish or cause to be  furnished  any  information
          concerning   its   business,    financial    condition,
          operations,  properties or prospects to another person,
          having any actual or  prospective  role with respect to
          any such Business Combination.

               (iii)  SRNB shall notify NVBancorp  immediately of
          the  details  of  any  indication  of  interest  of any
          person,  corporation,  firm,  association  or  group to
          acquire by any means a controlling  interest in SRNB or

               (iv)   Notwithstanding  anything  to the  contrary
          contained in this Agreement,  in the event the Board of
          Directors  of SRNB  receives  a bona  fide  unsolicited
          offer for a Business  Combination  of SRNB with another
          entity,  and  reasonably  determines,  upon  advice  of
          counsel,  that as a result of such  offer,  any duty to
          act or to refrain  from doing any act  pursuant to this
          Agreement is inconsistent with the continuing fiduciary
          duties of the Board of Directors  to its  shareholders,
          subject to the provisions of this Agreement  including,
          without  limitation,  Section  12.e.(ii) and the rights
          accorded  NVBancorp  thereunder  which shall  remain in
          effect,  such duty to act or to refrain  from doing any
          act shall be excused and such failure to act or refrain
          from doing any act shall not (a) constitute the failure
          of any  condition,  breach of any covenant or otherwise
          constitute any breach of this Agreement,  or (b) create
          any claim or cause of action  asserting  any  liability
          against any member of the Board of Directors of SRNB.

     3.3. Mutual Covenants of NVBancorp and SRNB.

Officer  and Chief Financial Officer, Shelton Francis,  Executive

                               -12-
<PAGE>

          b.    Appointment of Bank Directors.  At the  Effective
Time  of  the  Merger, all of the six (6) existing  directors  of
SRNB,  as  named  below, shall become members  of  the  Board  of
Directors  of the Resulting Bank, to serve until their successors
are  duly elected and qualified: William T. Kay, Jr., Dolores  M.
Vellutini,  Kevin  D.  Hartwick, Warren  L.  Murphy,  J.  Michael
McGowan  and Michael W. Martinez.  In addition, two  (2)  of  the
existing  directors  of  NVBancorp  (to  be  designated  by   the
NVBancorp  Board of Directors) shall also become members  of  the
Board of Directors of the Resulting Bank at the Effective Time of
the Merger.

          c.    Executive Management Committee.  From  and  after
the  Effective Time of the Merger, Michael W. Martinez, President
and Chief Executive Officer of SRNB, shall become a member of the
Executive Management Committee of NVBancorp.

          d.    Classified  Board of Directors.  After  execution
hereof,  the NVBancorp Board of Directors will adopt an amendment
(the  "Amendment") to the NVBancorp's Articles  of  Incorporation
("Articles")  and Bylaws to provide that the NVBancorp  Board  of
Directors shall be divided into three classes of directors,  each
consisting  of  a  number  of  directors  equal  as   nearly   as
practicable  to one-third the total number of directors,  for  so
long  as  such  Board  consists of at least nine  (9)  authorized
directors  and, in the event that the total number of  authorized
directors  on such Board is at least six (6) but less  than  nine
(9),  for  classification  of the Board  of  Directors  into  two
classes, each consisting of a number of directors equal as nearly
as  practicable  to  one-half  the  total  number  of  directors.
Pursuant  to  the  Amendment, each class of  directors  would  be
subject  to  election  every third year and  would  serve  for  a
three-year term for so long as the Board remained classified into
three classes, or would be subject to election every second  year
and  would serve for a two-year term in the event the Board  were
classified  into two classes. Currently, all of the directors  of
NVBancorp  are  elected  each year  to  serve  a  one-year  term.
NVBancorp  shall  cause the Amendment to  be  submitted  for  the
approval  of its shareholders, together with the other  principal
terms  of  the Merger, as provided in Section 3.3.e.  below.   In
connection with the approval of the Merger as provided in Section
3.3.e.,  SRNB  shall  advise  its shareholders  of  the  proposed
Amendment and inform its shareholders that their approval of  the
Merger  will constitute their consent to the Amendment.   If  the
Merger,  including the Amendment, is approved by the shareholders
of NVBancorp and SRNB, the NVBancorp Board of Directors will, for
purposes  of initial implementation, designate three  classes  of
directors for election at the 2000 Annual Meeting of Shareholders
of  NVBancorp, as follows:  Class I will be elected initially for
a  one-year term expiring at the 2001 NVBancorp Annual Meeting of
Shareholders; Class II will be elected initially for  a  two-year
term   expiring   at  the  2002  NVBancorp  Annual   Meeting   of
Shareholders; and Class III will be elected for a three-year term
expiring  at the NVBancorp Annual Meeting of Shareholders  to  be
held  in the year 2003; and, in each case, until their successors
are  duly elected and qualified. At each NVBancorp Annual Meeting
after  the 2000 Annual Meeting, only directors of the class whose
term is expiring would be voted upon, and upon election each such
director  would  serve  a three-year term.  Commencing  with  the

                               -13-
<PAGE>

NVBancorp  Annual Meeting of Shareholders scheduled to  occur  in
2001,  directors elected to Class I would serve for a  three-year
term  and  until their successors are duly elected and qualified,
subject  to  any  decrease  in  the total  number  of  authorized
directors,  as described above.  Subsequently, in the years  2002
and   2003,  directors  elected  to  Class  II  and  Class   III,
respectively,  would  also be elected for a three-year  term  and
until their successors are duly elected and qualified.

          e.    Approval  by  Shareholders.  NVBancorp  and  SRNB
shall  each  cause  the  principal terms  of  the  Merger  to  be
submitted   promptly  for  the  approval  of   their   respective
shareholders at meetings to be called and held in accordance with
applicable laws.  Subject to continuing fiduciary duties to their
shareholders, the Board of Directors of NVBancorp and  the  Board
of  Directors of SRNB, in authorizing the execution and  delivery
of this Agreement, unanimously recommend that the principal terms
of  the Merger be approved by their respective shareholders.   In
connection  with  the call of such meetings, NVBancorp  and  SRNB
shall  cause  the Joint Proxy Statement/Prospectus  described  in
Section  6  of  this Agreement to be mailed to  their  respective
shareholders.  Subject to its continuing fiduciary  duty  to  the
shareholders of NVBancorp or SRNB, as the case may be, the  Board
of  Directors  of  NVBancorp and the Board of Directors  of  SRNB
shall  at  all times prior to and during such meetings  of  their
respective shareholders recommend that the principal terms of the
Merger  be  approved  and, subject to such  duty,  use  its  best
efforts to cause such approvals.

          f.    Shareholder  Lists and Other Information.   After
execution hereof, each of NVBancorp and SRNB shall from  time  to
time  make available to the other party, upon request, a list  of
its  shareholders and their addresses and such other  information
as  the  other  party  shall  reasonably  request  regarding  the
ownership   of   the   common  stock  of  NVBancorp   and   SRNB,
respectively.

          g.    Government Approvals.  Each party  will  use  its
best  efforts  in  good faith to take or cause  to  be  taken  as
promptly  as practicable all such steps as shall be necessary  to
obtain  (i) the prior approval of the Merger and the transactions
contemplated pursuant to this Agreement and the Merger  Agreement

Agreement  and  this Agreement as promptly as  practicable.   All
approvals  referred  to  in this Section 3.3.g.  are  hereinafter
referred to as the "Government Approvals."

          otherwise acquire (other than in a fiduciary capacity),
          shares of or securities convertible into, capital stock
          or   other   equity  securities  of  their   respective
          companies,  or  enter  into  any  agreement,  call   or
          commitment  of any character so to do; grant  or  issue
          any stock option relating to or right to acquire shares
          of  their  capital stock or other equity  security;  or
          agree  to  do any of the foregoing, except as expressly
          provided  herein.   Nothing herein shall  prohibit  the
          issuance  of  shares upon exercise of  options  granted
          under  the  NVBancorp 1989 Director Stock Option  Plan,
          the NVBancorp 1998 Employee Stock Incentive Plan or the
          NVBancorp 1999 Director Stock Option Plan or  the  SRNB
          Stock  Option  Plan and outstanding at  the  time  this
          Agreement is executed; and

               (ii)  Neither NVBancorp nor SRNB shall declare, set
          aside  or  pay  any dividend or other  distribution  in
          respect   of  its  common  stock  (including,   without
          limitation,  any stock dividend or distribution)  other
          than regular quarterly or semi-annual cash dividends on
          its common stock in amounts substantially equivalent to
          cash  dividends paid in the two (2) years prior to  the
          date hereof (it being understood that declaration of  a
          quarterly  or  semi-annual cash dividend equal  to  the
          most  recent  previous quarterly  or  semi-annual  cash
          dividend will be deemed to meet this standard).

          n.     Access   to   Properties,  Books  and   Records;
Confidentiality.  Prior to the Effective Time of the Merger, each
party  shall  give each other party and its counsel,  independent
accountants and agents, full access during normal business  hours
and  upon  reasonable request, to all of its  properties,  books,
contracts, commitments and records including, but not limited to,
the   corporate,  financial  and  operational  records,   papers,
reports,  instructions, procedures, tax returns and  filings  tax
settlement letters, material contracts or commitments, regulatory
examinations and correspondences (but excluding any documents  or
materials subject to the attorney-client privilege or related  to
consideration of the Merger), and shall allow each other party to
make  copies of such materials (excluding regulatory examinations
and correspondence to the extent prohibited by applicable law  or
regulation)  and  shall furnish each other party  with  all  such
information  concerning  its affairs  as  each  other  party  may
reasonably  request.  Each party shall also use its best  efforts
to  cause its independent accountants to make available  to  each
other  party, its accountants, counsel and other agents,  to  the
extent reasonably requested in connection with such review,  such
independent  accountants' work papers and documentation  relating
to  its  work papers and its audits of the books and  records  of
each   party.   The  availability  or  actual  delivery  of  such
information  about  a  party  shall  not  affect  the  covenants,
representations  and warranties of any party  contained  in  this
Agreement and in the Merger Agreement.  Each party shall use  its
best   efforts  to  cause  its  officers,  directors,  employees,
auditors, independent accountants and attorneys to cooperate with
each  other  party  in its reasonable requests  for  information.

                               -19-
<PAGE>

Each  party  shall treat as confidential all such information  in
the  same  manner  as  each  party  treats  similar  confidential
information of its own, and if this Agreement is terminated, each
party   shall   continue  to  treat  all  such   information   as
confidential  and  to  cause  its  employees  to  keep  all  such
information   confidential  and  shall  return   such   documents
theretofore  delivered by each other party as  each  other  party
shall request, and shall use such information, or cause it to  be
used,  solely  for the purposes of evaluating and completing  the
transactions  contemplated hereby; provided that each  party  may
disclose  any such information to the extent required by  federal
or  state securities laws or otherwise required by any government
agency   or  regulatory  authority,  or  by  generally   accepted
accounting principles.  The foregoing confidentiality obligations
shall  not apply in respect of any information publicly available
or  to any information previously known to the party in question,
the  use  of  which is not otherwise restricted.  Notwithstanding
the  foregoing, the parties agree to comply with  the  terms  and
provisions of that certain Confidentiality Agreement entered into
between  the  parties dated June 22, 1999, and any  inconsistency
between   the   terms  and  provisions  of  that  Confidentiality
Agreement and the foregoing provisions shall be resolved in favor
of  the  terms  and  provisions contained in the  Confidentiality
Agreement.

          o.   Loan Performance.  From and after the date of this
Agreement  until the Effective Date, each party will  provide  to
the  other  the following reports for each such month  concurrent
with  the distribution of the monthly board report materials  for
the respective Boards of Directors of NVBancorp, NVB and SRNB:

               (i)    a status report on all loans  classified as
                      other assets specially  mentioned,  special
                      mention, substandard, doubtful or loss;

               (ii)   past due reports by loan;

               (iii)  non-accrual reports by loan;

               (v)    restructured loans reports; and

               (vi)   quarterly   call   reports   submitted   to
                      regulators during such month, if any.

          p.    Preparation  of Joint Proxy Statement/Prospectus.
SRNB  shall cooperate with NVBancorp in the preparation  pursuant
to  Section 6 hereof of a joint proxy statement and prospectus of

          q.     Rights  Plans.   Prior  to  the  date  of   this
Agreement,  each of NVBancorp and SRNB has adopted a rights  plan
with  respect  to its common stock and each has  entered  into  a
shareholder  rights  agreement.   NVBancorp  and  SRNB  agree  to
cooperate and take any and all action necessary or desirable from
time  to  time until the Effective Time of the Merger,  including
the  execution  of  an  amendment  to  either  or  both  of  such
shareholder  rights  agreements,  in  order  to  ensure  that  no
shareholder  rights will "flip-in" as a result of  the  execution
and  delivery  of  this Agreement or the Merger  or  any  of  the
transactions described herein.

4.   REPRESENTATIONS AND WARRANTIES OF SRNB.

     SRNB  represents and warrants to NVBancorp that,  except  as
set  forth on a schedule (the "SRNB Disclosure Schedule")  to  be
delivered  to NVBancorp within ten (10) business days  after  the
execution and delivery of this Agreement, corresponding in number
with the applicable section of this Agreement:

          a.     Corporate  Status  and  Power  to   Enter   Into
Agreements.    (i)  SRNB  is  a  national  banking   association,
organized  and  existing under the laws of the United  States  of
America,  (ii) subject to obtaining the Government Approvals  and
approval  of  the  principal terms of  the  Merger  by  the  SRNB
shareholders,  SRNB has all necessary corporate  power  to  enter
into this Agreement and the Merger Agreement and to carry out all
of  the terms and provisions hereof and thereof to be carried out
by  it, (iii) SRNB holds a currently valid national bank charter,
issued  by  the OCC to engage in the commercial banking  business
with offices in the State of California at the locations at which
it  is  licensed and currently conducts business, and (iv) except
for  the  Consent  Order  dated  April  12,  1999  (the  "Consent
Agreement") between SRNB and the OCC and as set forth in the SRNB
Disclosure  Schedule,  SRNB  is not  subject  to  any  directive,
resolution,  memorandum of understanding or order  of  the  FDIC,
FRB,  OCC  or  any other regulatory authority having jurisdiction
over its business or any of its assets or properties.  SRNB is in
substantial  compliance  in  all  material  respects   with   its
obligations  under the Consent Agreement.  Neither the  scope  of
the  business of SRNB nor the location of its properties requires
it  to be licensed to do business in any jurisdiction other  than
the State of California.  SRNB's deposits are insured by the FDIC
to the maximum extent permitted by applicable law and regulation.

          b.    Articles, Bylaws, Books and Records.  The  copies
of  the  Articles  of Association and Bylaws of  SRNB  heretofore
delivered  to NVBancorp are complete and accurate copies  thereof
as  in effect on the date hereof.  The minute books of SRNB  made
available to NVBancorp contain a complete and accurate record  of
all  meetings  of  SRNB's  Board  of  Directors  (and  committees
thereof)  and  shareholders.   The corporate  books  and  records
(including  financial  statements) of  SRNB  fairly  reflect  the
material  transactions to which SRNB is a party or by  which  its
properties are subject or bound, and such books and records  have
been properly kept and maintained.

          c.    Compliance  With Laws, Regulations  and  Decrees.
SRNB  (i)  has the corporate power to own or lease its properties
and  to conduct its business as currently conducted, (ii) to  its
knowledge, has complied in all material respects with, and is not
in  material default of any laws, regulations, ordinances, orders
or  decrees  applicable to the conduct of its  business  and  the
ownership  of  its properties, including but not limited  to  all
federal  and  state laws (including but not limited to  the  Bank
Secrecy  Act), rules and regulations relating to the offer,  sale
or  issuance  of  securities, and the operation of  a  commercial
bank,  other  than  where such noncompliance or  default  is  not
likely  to result in a material limitation on the conduct of  the
business  of SRNB or is not likely to otherwise have  a  material
adverse  effect on SRNB, (iii) has not failed to  file  with  the
proper  federal, state, local or other authorities  any  material
report  or other document required to be filed, and (iv) has  all
approvals,  authorizations, consents,  licenses,  clearances  and
orders  of,  and has currently effective all registrations  with,
all government and regulatory authorities which are necessary  to
the business and operations of SRNB as now being conducted.

          d.   Capitalization.  As of the date of this Agreement,
the  authorized  capital  stock of SRNB  consists  of  10,000,000
shares of SRNB common stock, par value $5.00 per share, of  which
1,476,128 shares are duly authorized, validly issued, fully  paid
and  nonassessable and currently outstanding.  Said capital stock
has  been  offered,  sold  and  issued  in  compliance  with  all
applicable  securities laws.  As of the date of  this  Agreement,
there are outstanding options to purchase 100,387 shares of  SRNB
common stock, at a weighted average exercise price of $12.47  per
share,  issued  pursuant  to the SRNB Stock  Option  Plan.   Said
options  were  issued and, upon issuance in accordance  with  the
terms of the outstanding options, said shares shall be issued, in
compliance with all applicable securities laws.  Otherwise, other
than  rights under the SRNB Rights Agreement dated as of  October
1,  1998, there are no outstanding (i) options, agreements, calls
or  commitments  of any character which would  obligate  SRNB  to
issue, sell, pledge, assign or otherwise encumber or dispose  of,
or  to  purchase,  redeem or otherwise acquire, any  SRNB  common
stock  or any other equity security of SRNB, or (ii) warrants  or
options  relating  to,  rights to  acquire,  or  debt  or  equity
securities convertible into, shares of SRNB common stock  or  any
other  equity security of SRNB.  The outstanding common stock  of
SRNB  is  registered with the Securities and Exchange  Commission
(the  "Commission") pursuant to Section 12(g) of  the  1934  Act.
Except  as  collateral for outstanding loans  held  in  its  loan
portfolio,  directly or indirectly, any equity  interest  in  any
bank, corporation or other entity.

          e.    Trademarks and Trade Names.  To the best  of  its
knowledge, SRNB (i) owns and has the exclusive right to  use  all
trademarks,  trade  names,  patents, copyrights,  service  marks,
trade    secrets,   or   other   intellectual   property   rights
(collectively,  "Intellectual  Property  Rights")  used   in   or
necessary  for  the conduct of its business as now or  heretofore
conducted;  and  (ii)  its not infringing upon  the  Intellectual
Property  Rights  of  any other person or entity.   No  claim  is
pending  or  threatened  by  any  person  or  entity  against  or
otherwise affecting the use by SRNB of any Intellectual  Property
Rights and, to the best of its knowledge, there is no valid basis
for any such claim.

          f.    Financial  Statements,  Regulatory  Reports.   No
financial statement or other document provided or to be  provided
to NVBancorp as required by Section 3.3(i) hereof, as of the date
of  such  document, contained, or as to documents to be delivered
after  the date hereof, will contain, any untrue statement  of  a
material fact, or, at the date thereof, omitted or will  omit  to
state  a  material fact necessary in order to make the statements
contained therein, in light of the circumstances under which such
statements  were  or  will  be made,  not  misleading;  provided,
however,  that information as of a later date shall be deemed  to
modify  contrary information as of any earlier  date.   SRNB  has
filed all material documents and reports required to be filed  by
them  with  the OCC and any other government agency or regulatory
authority  having  jurisdiction  over  its  business,  assets  or
properties.   All  such reports conform in all material  respects
with the requirements promulgated by such government agencies and
regulatory  authorities.   All compliance  or  corrective  action
relating  to SRNB required by government agencies and  regulatory
authorities having jurisdiction over SRNB has been taken.  Except
as  disclosed in such statements, reports or documents, SRNB have
not  received any notification, formally or informally, from  any
agency or department of any federal, state or local government or
any  regulatory authority or the staff thereof (i) asserting that
it  is not in compliance with any of the statutes, regulations or
ordinances   which   such  government  or  regulatory   authority
enforces,  or (ii) threatening to revoke any license,  franchise,
permit   or   government  authorization.   SRNB  has   paid   all
assessments made or imposed by any government agency.   SRNB  has
delivered  to  NVBancorp copies of all annual management  letters
and  opinions, and has made available to NVBancorp for inspection
all  reviews, correspondence and other documents in the files  of
SRNB prepared by certified public accountants engaged by SRNB and
delivered to SRNB since December 31, 1994.  The financial records
of  SRNB have been, and are being and shall be, maintained in all
material  respects  in accordance with all applicable  legal  and
accounting   requirements   sufficient   to   insure   that   all
transactions  reflected  therein are, in all  material  respects,
executed  in  accordance with management's  general  or  specific
authorization and recorded in conformity with generally  accepted
accounting principles at the time in effect.  The data processing
equipment,   data  transmission  equipment,  related   peripheral
equipment  and  software used by SRNB in  the  operation  of  its
business  to  generate  and retrieve its  financial  records  are
adequate for the current needs of SRNB.

          g.   Tax Returns.

                  (i)     SRNB  has  timely  filed  all  federal,
          state,  county, local and foreign tax returns  required
          to  be  filed  by  it,  including, without  limitation,
          estimated  tax, use tax, excise tax, real property  and
          personal  property tax reports and returns,  employer's
          withholding tax returns, other withholding tax  returns
          and  Federal  Unemployment Tax Returns, and  all  other
          reports  or other information required or requested  to
          be filed by SRNB, and each such return, report or other
          information  was, when filed, complete and accurate  in
          all  material respects.  SRNB has paid all taxes,  fees
          and  other  government charges, including any  interest

                               -23-
<PAGE>

          and  penalties  thereon, when  they  have  become  due,
          except  those that are being contested in  good  faith,
          which   contested  matters  have  been   disclosed   to
          NVBancorp.  SRNB has not been requested to give nor has
          it  given any currently effective waivers extending the
          statutory  period of limitation applicable to  any  tax
          return  required  to  be filed by it  for  any  period.
          There  are  no  claims  pending against  SRNB  for  any
          alleged  deficiency in the payment of  any  taxes,  and
          SRNB does not know of any pending or threatened audits,
          investigations or claims for unpaid taxes  or  relating
          to  any liability in respect of any taxes.  There  have
          been  no events, including a change in ownership,  that
          would  result in a reappraisal and establishment  of  a
          new  base-year  full value for purposes  of  applicable
          provisions of the California Constitution, of any  real
          property  owned in whole or in part by SRNB or  to  the
          best  of SRNB's knowledge, of any real property  leased
          by SRNB.

                  (ii)    SRNB  has   heretofore   delivered   to
          NVBancorp copies of all its tax returns with respect to
          taxes  payable to the United  States of America and the
          State of California for the fiscal years ended December
          31, 1998, 1997, 1996, 1995 and 1994.

                  (iii)   No consent  has been filed  relating to
          SRNB pursuant to Section 341(f) of the IRC.

          h.    Material  Adverse Change.  Except  as  heretofore
disclosed  in writing by SRNB to NVBancorp, since June 30,  1999,
there  has  been (i) no material adverse change in the  business,
assets,  licenses, permits, franchises, results of operations  or
financial  condition  of SRNB (whether or  not  in  the  Ordinary
Course  of  Business),  (ii) no change  in  any  of  the  assets,
licenses,  permits  or franchises of SRNB that  has  had  or  can
reasonably be expected to have a material adverse effect  on  any
of  the  items  listed in clause (h)(i) above, (iii)  no  damage,
destruction,  or other casualty loss (whether or not  covered  by
insurance) that has had or can reasonably be expected to  have  a
material  adverse  effect on any of the items  listed  in  clause
(h)(i) above, (iv) no amendment, modification, or termination  of
any  existing, or entering into of any new, contract,  agreement,
plan, lease, license, permit or franchise that is material to the
business,  financial condition, assets, liabilities or operations
of  SRNB, except in the Ordinary Course of Business; and  (v)  no
disposition  by SRNB of one or more assets that, individually  or
in the aggregate, are material to SRNB, except sales of assets in
the Ordinary Course of Business.

          i.    No Undisclosed Liabilities.  Except for items for
which  reserves  have been established in the  unaudited  balance
sheets  of  SRNB  as of June 30, 1999, SRNB has not  incurred  or
discharged,  and  is not legally obligated with respect  to,  any
indebtedness,   liability  (including,  without   limitation,   a
liability  arising  out  of an indemnification,  guarantee,  hold
harmless  or  similar  arrangement)  or  obligation  (accrued  or

                               -24-
<PAGE>

contingent,  whether due or to become due,  and  whether  or  not
subordinated to the claims of its general creditors), other  than
as  a  result  of operations in the Ordinary Course  of  Business
after  such  date.  No agreement pursuant to which any  loans  or
other assets have been or will be sold by SRNB entitles the buyer
of  such loans or other assets, unless there is a material breach
of  a  representation  or  covenant by SRNB,  to  cause  SRNB  to
repurchase  such loan or other asset or to pursue any other  form
of  recourse against SRNB.  SRNB has not knowingly made or  shall
make  any  representation or covenant in any such agreement  that
contained  or  shall contain any untrue statement of  a  material
fact  or omitted or shall omit to state a material fact necessary
in  order  to make the statements contained therein, in light  of
the   circumstances  under  which  such  representations   and/or
covenants were made or shall be made, not misleading.   No  cash,
stock or other dividend or any other distribution with respect to
the  SRNB  Shares has been declared, set aside or paid, nor  have
any  of  the  SRNB Shares been purchased, redeemed  or  otherwise
acquired,  directly  or indirectly, by SRNB  since  December  31,
1996.

          j.   Properties and Leases.

                (i) SRNB has good and marketable title, free  and
          clear  of  all liens and encumbrances and the right  of
          possession, subject to existing leaseholds, to all real
          properties and good title, free and clear of all  liens
          and  encumbrances,  to all other property  and  assets,
          tangible and intangible, reflected in the SRNB  balance
          sheet  as  of  June 30, 1999 (except property  held  as
          lessee  under leases disclosed in writing prior to  the
          date  hereof  and  except  personal  property  sold  or
          otherwise  disposed  of since June  30,  1999,  in  the
          Ordinary Course of Business), except for (a) liens  for
          taxes  or  assessments not delinquent, (b)  such  other
          liens and encumbrances and imperfections of title as do
          not  materially  affect the value of such  property  as
          reflected  in  the SRNB balance sheet as  of  June  30,
          1999, or as currently shown on the books and records of
          SRNB  and  which do not interfere with  or  impair  its
          present  and continued use, or (c) exceptions disclosed
          in  title reports and preliminary title reports, copies
          of  which  have  been provided to  NVBancorp.   To  the
          knowledge  of  SRNB,  all tangible properties  of  SRNB
          conform  in  all material respects with all  applicable
          ordinances, regulations and zoning laws.  All  tangible
          properties  of SRNB are in a good state of  maintenance
          and repair and are adequate for the current business of
          SRNB.   No  properties of SRNB, and,  to  the  best  of
          SRNB's  knowledge, no properties in which SRNB holds  a
          collateral  or contingent interest or purchase  option,
          are   the   subject  of  any  pending   or   threatened
          investigation, claim or proceeding relating to the use,
          storage   or   disposal   on  such   property   of   or
          contamination  of  such  property  by  any   toxic   or
          hazardous waste material or substance.  To the best  of
          its  knowledge, SRNB does not own, possess  or  have  a
          collateral or contingent interest or purchase option in
          any  properties or other assets which contain  or  have

                               -25-
<PAGE>

          located within or thereon any hazardous or toxic  waste
          material  or  substance unless  the  location  of  such
          hazardous or toxic waste material or other substance or
          its  use thereon conforms in all material respects with
          all  federal, state and local laws, rules,  regulations
          or   other  provisions  regulating  the  discharge   of
          materials  into  the  environment.   As  to  any   real
          property  not  owned  or leased by  SRNB  and  held  as
          security for a loan or in which SRNB otherwise  has  an
          interest,   SRNB  has  not  controlled,   directed   or
          participated in the operation or management of any such
          real property or any facilities or enterprise conducted
          thereon,  such that it has become an owner or  operator
          of  such  real  property under applicable environmental
          laws.

                (ii)      All  properties   held  by  SRNB  under
          leases are held under  valid,  binding and  enforceable
          leases, with such exceptions as are not material and do
          not interfere with the conduct of the business of SRNB,
          and SRNB enjoys quiet and peaceful  possession  of such
          leased property. SRNB is not in material default in any
          respect   under  any  material   lease,   agreement  or
          obligation  regarding  its  properties to which it is a
          party or by which it is bound.

                (iii)     Except  as disclosed  to  NVBancorp  in
          writing, all of SRNB's rights and obligations under the
          leases  referred to in Section 4(j)(ii)  above  do  not
          require  the  consent  of  any  other  party   to   the
          transaction  contemplated by  this  Agreement  and  the
          Merger  Agreement.  Where required, SRNB shall  obtain,
          prior  to  the  Effective Date,  the  consent  of  such
          parties to such transaction.

          k.    Material Contracts.  Except as disclosed  in  the
SRNB  Disclosure Schedule  and excluding loans, lines of  credit,
loan  commitments or letters of credit to which SRNB is a  party,
SRNB  is  not  a  party  to or bound by  any  contract  or  other
agreement made in the Ordinary Course of Business which  involves
aggregate  future payments by or to SRNB of more than Twenty-five
Thousand  Dollars ($25,000) and which is made for a fixed  period
expiring more than one year from the date hereof, and SRNB is not
a  party  to  or bound by any agreement not made in the  Ordinary
Course of Business which is to be performed at or after the  date
hereof.   Each  of  the  contracts and  agreements  disclosed  to
NVBancorp  pursuant to this Section 4(k) is a legal  and  binding
obligation  (subject  to  applicable bankruptcy,  insolvency  and
similar  laws affecting creditors' rights generally and  subject,
as   to   enforceability,  to  equitable  principles  of  general
applicability), and no breach or default (and no condition which,
with notice or passage of time, or both, could become a breach or
default) exists with respect thereto.

          l.   Classified Loans.  Except as disclosed in the SRNB
Disclosure Schedule, there are no loans presently owned  by  SRNB
that  have  been classified by SRNB management or  SRNB  internal
policy  or procedure, any outside review examiner, accountant  or

                               -26-
<PAGE>

any  bank regulatory authority as "Non-Accrual," "Watch,"  "Other
Assets Specially Mentioned," "Substandard," "Doubtful," or "Loss"
or  classified using categories or words with similar import  and
all  loans  or  portions thereof so classified  shall  have  been
reserved  to  the  extent required.  SRNB  regularly  review  and
appropriately  classify  their  loans  in  accordance  with   all
applicable  legal  and  regulatory  requirements  and   generally
accepted  banking practices.  All loans and investments  of  SRNB
are   legal,   valid  and  binding  obligations  enforceable   in
accordance with their respective terms and are not subject to any
setoffs,   counterclaims  or  disputes  (subject  to   applicable
bankruptcy,  insolvency  and similar  laws  affecting  creditors'
rights  generally and subject, as to enforceability, to equitable
principles of general applicability), except as disclosed in  the
SRNB Disclosure Schedule or reserved for in the unaudited balance
sheet of SRNB as of June 30, 1999, and were duly authorized under
and made in compliance with applicable federal and state laws and
regulations.   SRNB  does  not have  any  extensions  of  credit,
investments,    guarantees,   indemnification    agreements    or
commitments   for   the   same  (including   without   limitation
commitments to issue letters of credit, to create acceptances, or
to  repurchase  securities, federal funds or other assets)  other
than those documented on the books and records of SRNB.

          m.     No  Restrictions  on  Investments.   Except  for
pledges  to  secure  public  and trust  deposits  and  repurchase
agreements  in  the  Ordinary Course of Business  and  securities
classified as "held-to-maturity" as defined under SFAS  No.  115,
none of the investments reflected in the SRNB balance sheet as of
June  30,  1999, and none of the investments made by  SRNB  since
June 30, 1999, is subject to any restriction, whether contractual
or  statutory, which materially impairs the ability  of  SRNB  to
freely dispose of such investment at any time.

          n.     Employment Benefit Plans/ERISA.

               (i)        SRNB  has  provided  to  NVBancorp   an
          accurate   list  setting  forth  all  bonus,  incentive
          compensation,   profit-sharing,  pension,   retirement,
          stock  purchase,  stock option, deferred  compensation,
          severance,  hospitalization, medical,  dental,  vision,
          group  insurance, death benefit, disability  and  other
          fringe  benefit  plans, trust agreements,  arrangements
          and  commitments of SRNB (including but not limited  to
          any    such   plans,   agreements,   arrangements   and
          commitments applicable to former employees  or  retired
          employees,  or  for  which such persons  are  eligible)
          (collectively, "Employee Plans"), if any, together with
          copies  of  all such Employee Plans that are documented
          and  any and all contracts of employment, and has  made
          available to NVBancorp any Board of Directors'  minutes
          (or   committee  minutes)  authorizing,  approving   or
          guaranteeing such Employee Plans and contracts; and

               (ii)       All  contributions, premiums  or  other
          payments due from SRNB to (or under) any Employee Plans
          have  been  fully  paid or adequately provided  for  on
          SRNB's audited financial statements for the year  ended
          December 31, 1998 or unaudited financial statements for

                               -27-
<PAGE>

          the  six  (6) months ended June 30, 1999.  All accruals
          thereon  (including,  where  appropriate,  proportional
          accruals  for  partial  periods)  have  been  made   in
          accordance    with   generally   accepted    accounting
          principles consistently applied on a reasonable  basis;
          and

               (iii)      SRNB  has   disclosed   in  writing  to
          NVBancorp  the  names  of each  director,  officer  and
          employee of SRNB; and

               (iv)       The    Employee    Plans    have   been
          administered  where required in substantial  compliance
          with  ERISA,  the IRC and the  terms  of such  Employee
          Plans, and there is no pending or threatened litigation
          relating to any such Employee Plan; and

               (v)        SRNB has not offered in the past health
          benefits for retired  employees and has no intention to
          offer  any  additional  health  or other  benefits  for
          retired employees; and

               (vi)       Each Employee Plan is in full force and
          effect, and neither SRNB nor any other party thereto is
          in material  default under any of them,  and there have
          been no  claims  of  default  and there are no facts or
          conditions  which  if  continued,  or on  notice,  will
          result in a material  default under any Employee Plans;
          and

               (vii)     SRNB has provided to NVBancorp a list of
          all  agreements  or  other understandings  pursuant  to
          which the consummation of the transactions contemplated
          hereby  will (a) entitle any current or former employee
          or  officer  of  SRNB  to severance  pay,  unemployment
          compensation  or any other payment, or  (b)  accelerate
          the  time of payment or vesting or increase the  amount
          of compensation due any such employee or officer.

          o.    Collective Bargaining and Employment  Agreements.
Except  as  provided in this Agreement or as previously disclosed
to  NVBancorp and NVB in writing, SRNB does not have any union or
collective bargaining or written employment agreements, contracts
or  other  agreements  with any labor organization  or  with  any
member of management, or any management or consultation agreement
not  terminable  at will by SRNB without liability  and  no  such
contract  or  agreement  has  been  requested  by,  or  is  under
discussion by management with, any group of employees, any member
of  management  or  any  other person.   There  are  no  material
controversies  pending  between SRNB and any  current  or  former
employees,  and  to the best of SRNB's knowledge,  there  are  no
efforts  presently  being  made by any  labor  union  seeking  to
organize any of such employees.

                               -28-
<PAGE>

          p.   Compensation of Officers and Employees.  Except as
disclosed  in  the SRNB Disclosure Schedule,  (i) no  officer  or
employee of SRNB is receiving aggregate direct remuneration at  a
rate exceeding Seventy-five Thousand Dollars ($75,000) per annum,
and  (ii)  the  consummation of the transactions contemplated  by
this Agreement and the Merger Agreement will not (either alone or
upon  the occurrence of any additional or further acts or events)
result  in  any  payment (whether of severance pay or  otherwise)
becoming due from SRNB or NVBancorp to any employee of SRNB.

          q.     Legal   Actions  and  Proceedings.   Except   as
disclosed  in the SRNB Disclosure Schedule, SRNB is not  a  party
to,  or  so  far as known to it, threatened with, and  to  SRNB's
knowledge, there is no reasonable basis for, any legal action  or
other   proceeding  or  investigation  before  any   court,   any
arbitrator of any kind or any government agency, and SRNB is  not
subject  to  any  potential adverse claim, the outcome  of  which
could  involve  the payment or receipt by SRNB of any  amount  in
excess  of  Twenty-five  Thousand Dollars  ($25,000),  unless  an
insurer  has agreed to defend against and pay the amount  of  any
resulting  liability without reservation, or, if any  such  legal
action,  proceeding, investigation or claim will not involve  the
payment by SRNB of a monetary amount, which could have a material
adverse  effect  on  SRNB  or its business  or  property  or  the
transactions contemplated hereby.  SRNB has no knowledge  of  any
pending  or  threatened  claims or charges  under  the  Community
Reinvestment   Act,  before  the  Equal  Employment   Opportunity
Commission, the California Department of Fair Housing &  Economic
Development,  the California Unemployment Appeals Board,  or  any
federal or state human relations commission or agency.  There  is
no  labor dispute, strike, slow-down or stoppage pending  or,  to
the best of the knowledge of SRNB, threatened against SRNB.

          r.   Execution and Delivery of the Agreement.

               (i)        The  execution  and  delivery  of  this
          Agreement  and the  Merger  Agreement  have  been  duly
          authorized  by the Board of Directors of SRNB and, when
          the principal  terms of the Merger,  this Agreement and
          the Merger  Agreement  have been duly  approved  by the
          affirmative  vote of the holders of  two-thirds  of the
          outstanding  SRNB  Shares at a meeting of  shareholders
          duly called and held,  the Merger,  this  Agreement and
          the  Merger   Agreement   will  be  duly  and   validly
          authorized  by all  necessary  corporate  action on the
          part of SRNB.

               (ii)       This  Agreement  has been duly executed
          and  delivered by SRNB and  (assuming due execution and
          delivery  by  NVBancorp)  constitutes,  and the  Merger
          Agreement, upon its execution and delivery by SRNB (and
          assuming due execution and delivery by NVBancorp)  will
          constitute,  a legal and binding  obligation of SRNB in
          accordance with its terms.

                               -29-
<PAGE>

               (iii)      The  execution  and delivery by SRNB of
          this  Agreement  and  the  Merger   Agreement  and  the
          consummation  of the  transactions  herein and  therein
          contemplated  (a) do not violate any  provision  of the
          Articles of  Association  or Bylaws of SRNB, or violate
          in any  material  respect any  provision  of federal or
          state  law  or  any   government   rule  or  regulation
          (assuming (1) receipt of the Government Approvals,  (2)
          receipt  of the  requisite  SRNB  shareholder  approval
          referred  to  in  Section  4(r)(i)   hereof,   (3)  due
          registration  of the  NVBancorp  Shares  under the 1933
          Act,  and  (4)  receipt  of   appropriate   permits  or
          approvals  under state  securities or "blue sky" laws),
          and (b) do not require any consent of any person under,
          conflict in any  material  respect  with or result in a
          material  breach  of,  or  accelerate  the  performance
          required  by any of the terms  of,  any  material  debt
          instrument,  lease,  license,  covenant,  agreement  or
          understanding  to which  SRNB is a party or by which it
          is  bound  or  any  order,  ruling,  decree,  judgment,
          arbitration  award  or  stipulation  to  which  SRNB is
          subject, or constitute a material default thereunder or
          result in the  creation  of any lien,  claim,  security
          interest, encumbrance,  charge, restriction or right of
          any third party of any kind  whatsoever upon any of the
          properties or assets of SRNB.

          s.    Retention  of Broker or Consultant.   No  broker,
agent,  finder,  consultant or other  party  (other  than  legal,
compliance,  loan  reviewers and accounting  advisors)  has  been
retained  by  SRNB  or  is entitled to be  paid  based  upon  any
agreements,  arrangements  or  understandings  made  by  SRNB  in
connection  with  any  of the transactions contemplated  by  this
Agreement  or the Merger Agreement, except that SRNB has  engaged
the  firm of Hoefer & Arnett, Inc. to provide consulting services
to  SRNB,  including  an opinion regarding the  fairness  of  the
consideration to be received by SRNB shareholders in the  Merger.
SRNB has provided NVBancorp with a true and accurate copy of  its
agreement(s) with Hoefer & Arnett, Inc.

          t.    Insurance.   SRNB is and continuously  since  its
inception  has been, insured with reputable insurers against  all
risks normally insured against by banks, and all of the insurance
policies  and  bonds maintained by SRNB are  in  full  force  and
effect, SRNB is not in default thereunder and all material claims
thereunder  have  been filed in due and timely fashion.   In  the
best  judgment of the management of SRNB, such insurance coverage
is  adequate  for SRNB.  Since December 31, 1998, there  has  not
been any damage to, destruction of, or loss of any assets of SRNB
not  covered  by  insurance that could have  a  material  adverse
effect  on the business, financial condition, properties,  assets
or results of operations of SRNB.

          u.   Loan Loss Reserves.  The allowance for loan losses
in  the  SRNB  balance sheets dated December 31, 1998,  June  30,
1999,  and as of the Determination Date are and will be  adequate
in all material respects under the requirements of all applicable
state  and  federal laws and regulations to provide for  possible
loan  losses on outstanding loans, net of recoveries.   SRNB  has

                               -30-
<PAGE>

disclosed  to NVBancorp in writing prior to the date hereof,  and
will  promptly  inform  NVBancorp of the amounts  of  all  loans,
leases,  other  extensions  of credit or  commitments,  or  other
interest-bearing assets of SRNB, that have been classified as  of
the  date hereof or hereafter by SRNB management or SRNB internal
policy  or procedure, any outside review examiner, accountant  or
any   bank   regulatory  authority  as  "Other  Loans   Specially
Mentioned,"  "Special  Mention,"  "Substandard,"  "Doubtful,"  or
"Loss"  or  classified  using categories or  words  with  similar
import  in  the  case  of  loans (or  that  would  have  been  so
classified,  in  the case of other interest-bearing  assets,  had
they been loans).  Notwithstanding the above, SRNB shall be under
no obligation to disclose to NVBancorp any such classification by
any bank regulatory authority where such disclosure would violate
any  obligation of confidentiality of SRNB imposed by  such  bank
regulatory  authority.  SRNB has furnished and will  continue  to
furnish to NVBancorp true and accurate information concerning the
loan  portfolio of SRNB, and no material information with respect
to  the  loan  portfolio  has  been  or  will  be  withheld  from
NVBancorp.

          v.    Transactions  With  Affiliates.   Except  in  the
Ordinary  Course  of  Business, SRNB  has  not  extended  credit,
committed itself to extend credit, or transferred any asset to or
assumed or guaranteed any liability of the employees or directors
of  SRNB, or to any spouse or child of any of them, or to any  of
their  "affiliates" or "associates" as such terms are defined  in
Rule 405 under the 1933 Act.  SRNB has not entered into any other
transactions  with  the employees or directors  of  SRNB  or  any
spouse  or  child of any of them, or any of their  affiliates  or
associates,  except as disclosed in writing  to  NVBancorp.   Any
such  transactions have been on terms no less favorable  to  SRNB
than those which would prevail in an arms-length transaction with
an independent third party.  SRNB has not violated any applicable
regulation  of  any  government agency  or  regulatory  authority
having  jurisdiction  over  SRNB  in  connection  with  any  such
transactions described in this subsection

          w.    Risk  Management Instruments.  All interest  rate
swaps,  caps,  floors,  option agreements,  futures  and  forward
contracts and other similar risk management arrangements, whether
entered  into for SRNB's own account (all of which are listed  on
the  SRNB  Disclosure  Schedule), if any, were  entered  into  in
accordance  with  prudent business practices and  all  applicable
laws,  rules,  regulations  and  regulatory  policies  and   with
counterparties  believed  to be financially  responsible  at  the
time;  and each of them constitutes the valid and legally binding
obligation  of  SRNB, enforceable in accordance  with  its  terms
(except   as   enforceability  may  be  limited   by   applicable
bankruptcy,  insolvency, reorganization,  moratorium,  fraudulent
transfer and similar laws of general applicability relating to or
affecting creditors' rights or by general equity principles), and
are  in  full  force  and effect.  Neither SRNB,  nor  to  SRNB's
knowledge,  any other party thereto, is in breach of any  of  its
obligations under any such agreement or arrangement.

          x.    Year 2000.  To the knowledge of SRNB, the mission
critical computer software operated by SRNB is currently  capable

                               -31-
<PAGE>

of  providing,  or  is  being adapted to  provide,  uninterrupted
millennium  functionality to record, store, process  and  present
calendar   dates  falling  on  or  after  January  1,   2000   in
substantially  the  same manner and with substantially  the  same
functionality as such mission critical software records,  stores,
processes  and presents such calendar dates falling on or  before
December  31,  1999.   To the knowledge of  SRNB,  the  costs  of
adaptations referred to in this clause will not have  a  material
adverse  effect  with respect to the business and  operations  of
SRNB.   SRNB has not received, and does not reasonably expect  to
receive,   any   deficiency  notice  from  any  federal   banking
authority.  SRNB has previously disclosed to NVBancorp a complete
and  accurate  copy  of  its  plan,  including  an  estimate   of
anticipated associated costs, for addressing the issues set forth
in   all   Federal  Financial  Institutions  Examination  Council
Interagency  Statements as such issues affect SRNB.  Between  the
date  of  this Agreement and the Effective Time, SRNB  shall  use
commercially reasonable and practicable efforts to implement such
plan.

          y.   Community Reinvestment Act Compliance.  SRNB is in
substantial  compliance  with the applicable  provisions  of  the
Community   Reinvestment  Act  of  1977   and   the   regulations
promulgated thereunder (collectively, the "CRA") and has received
a  CRA  rating of "satisfactory" from the OCC in its most  recent
examination,  and SRNB has no knowledge of the existence  of  any
fact or circumstance or set of facts or circumstances which could
be  reasonably  expected  to result in  SRNB  failing  to  be  in
substantial compliance with such provisions or having its current
rating lowered.

          z.    Information in NVBancorp Registration  Statement.
The  information  pertaining to SRNB which has been  or  will  be
furnished to NVBancorp for or on behalf of SRNB for inclusion  in
the   NVBancorp  Registration  Statement  and  the  Joint   Proxy
Statement/Prospectus,  or  in the applications  to  be  filed  to
obtain  the Government Approvals (the "Applications"),  does  not
and will not contain any untrue statement of any material fact or
omit  or  will  omit to state any material fact  required  to  be
stated  therein or necessary to make the statements  therein,  in
light  of  the  circumstances under  which  they  are  made,  not
misleading; provided, however, that information of a  later  date
shall  be deemed to modify contrary information as of an  earlier
date.  All financial statements of SRNB included in the NVBancorp
Registration  Statement and the Joint Proxy Statement/Prospectus,
or  the Applications, will present fairly the financial condition
and  results  of  operations of SRNB at the  dates  and  for  the
periods  covered by such statements in accordance with  generally
accepted  accounting principles consistently  applied  throughout
the  periods  covered  by such statements.  SRNB  shall  promptly
advise NVBancorp in writing if prior to the Effective Time of the
Merger  SRNB shall obtain knowledge of any facts that would  make
it  necessary  to amend or supplement the NVBancorp  Registration
Statement,   the   Joint   Proxy  Statement/Prospectus   or   any
Application,  in  order  to  make  the  statements  therein   not
misleading or to comply with applicable law or regulation.

          aa.  Accuracy and Effective Date of Representations and
Warranties,   Covenants  and  Agreements.   Each  representation,
warranty,  covenant  and  agreement of SRNB  set  forth  in  this
Agreement shall be deemed to be made on and as of the date hereof
(except  to  the  extent  that a representation  or  warranty  is
qualified as set forth in a Schedule corresponding in number with
the  applicable  section of such representation or  warranty  and
delivered on or before the Document Delivery Date, and upon  such
delivery  it  shall  be deemed made on and  as  of  the  date  of
delivery), the Closing Date and the Effective Time of the Merger.
No  representation or warranty by SRNB, and no statement by  SRNB
in   any  certificate,  agreement,  schedule  or  other  document
furnished  or to be furnished in connection with the transactions
contemplated  by this Agreement or the Merger Agreement,  was  or
will  be  inaccurate,  incomplete or incorrect  in  any  material
respect as of the date furnished or contains or will contain  any
untrue  statement of a material fact or omits  or  will  omit  to
state  any  material fact necessary to make such  representation,
warranty or statement not misleading to NVBancorp.

5.   REPRESENTATIONS AND WARRANTIES OF NVBancorp.

     In   the  following  representations  and  warranties,   all
references   to   assets,   liabilities,   properties,    rights,
obligations,   financial   condition,   operations,    knowledge,
information  and  other  characteristics of  NVBancorp  shall  be
deemed to include reference to those characteristics of NVBancorp
on   a  consolidated  basis,  except  as  the  context  otherwise
indicates or requires.  NVBancorp represents and warrants to SRNB
that,   except  as  set  forth  on  a  schedule  (the  "NVBancorp

business of NVBancorp nor the location of its properties requires
NVBancorp  or  NVB  to  be  licensed  to  do  business   in   any
jurisdiction other than the State of California.  NVB's  deposits

limited  to all federal and state laws (including but not limited
to  the Bank Secrecy Act), rules and regulations relating to  the
offer,  sale  or issuance of securities, and the operation  of  a
commercial  bank, other than where such noncompliance or  default

of the business of NVBancorp or is not likely to otherwise have a
material  adverse effect on NVBancorp and NVB taken as  a  whole,
(iii)  have  not  failed to file with the proper federal,  state,
local  or other authorities any material report or other document

there  are  currently  outstanding options  to  purchase  484,096
shares  of NVBancorp common stock, at a weighted average exercise
price of $11.39 per share, issued pursuant to the NVBancorp  1989

Incentive Plan and the NVBancorp 1999 Director Stock Option Plan.
Said  options  were issued and, upon issuance in accordance  with
the terms of the outstanding options said shares shall be issued,
in  compliance  with all applicable securities laws.   Otherwise,
other  than  rights  under the NVBancorp  Shareholder  Protection
Rights  Agreement  dated as of September 9, 1999,  there  are  no
outstanding (i) options, agreements, calls or commitments of  any
character which would obligate NVBancorp to issue, sell,  pledge,

                               -34-
<PAGE>

assign  or  otherwise  encumber or dispose of,  or  to  purchase,
redeem  or otherwise acquire, any NVBancorp common stock  or  any
other  equity security of NVBancorp, or (ii) warrants or  options
relating  to,  rights  to acquire, or debt or  equity  securities
convertible into, shares of NVBancorp common stock or  any  other
equity  security  of  NVBancorp.   NVBancorp  owns  all  of   the
outstanding  equity securities of NVB.  Except as collateral  for
outstanding   loans  held  in  their  loan  portfolios,   neither
NVBancorp  nor  NVB  owns,  directly or  indirectly,  any  equity
interest  in any bank (other than NVBancorp's ownership of  NVB),
corporation or other entity.

          e.    Trademarks  and  Trade Names.   To  the  best  of
NVBancorp's  knowledge, NVBancorp and NVB (i) own  and  have  the
exclusive right to use all Intellectual Property Rights  used  in
or  necessary  for  the  conduct of their businesses  as  now  or
heretofore  conducted;  and  (ii) are  not  infringing  upon  the
Intellectual Property Rights of any other person or  entity.   No
claim is pending or threatened by any person or entity against or
otherwise  affecting  the  use  by  NVBancorp  or  NVB   of   any
Intellectual  Property Rights and, to the best of its  knowledge,
there is no valid basis for any such claim.

          f.    Financial  Statements,  Regulatory  Reports.   No
financial statement or other document provided or to be  provided
to  SRNB as required by Section 3.3(i) hereof, as of the date  of
such  document,  contained, or as to documents  to  be  delivered
after  the date hereof, will contain, any untrue statement  of  a
material fact, or, at the date thereof, omitted or will  omit  to
state  a  material fact necessary in order to make the statements
contained therein, in light of the circumstances under which such
statements  were  or  will  be made,  not  misleading;  provided,
however,  that information as of a later date shall be deemed  to
modify  contrary  information as of any earlier date.   NVBancorp
has filed all material documents and reports required to be filed
by  it  with the Commission, FDIC, FRB, the California Department
of  Financial  Institutions and any other  government  agency  or
regulatory  authority  having jurisdiction over  their  business,
assets  or properties.  All such reports conform in all  material
respects  with  the requirements promulgated by  such  government
agencies   and   regulatory  authorities.   All   compliance   or
corrective  action  relating to NVBancorp  and  NVB  required  by
government    agencies   and   regulatory   authorities    having
jurisdiction  over NVBancorp or NVB has been  taken.   Except  as
disclosed  in  such  statements, reports  or  documents,  neither
NVBancorp  nor  NVB  has received any notification,  formally  or
informally,  from any agency or department of any federal,  state
or  local  government or any regulatory authority  or  the  staff
thereof  (a) asserting that it is not in compliance with  any  of
the statutes, regulations or ordinances which such government  or
regulatory  authority enforces, or (b) threatening to revoke  any
license,   franchise,   permit   or   government   authorization.
NVBancorp  and NVB have paid all assessments made or  imposed  by
any government agency.  NVBancorp has delivered to SRNB copies of
all   annual  management  letters  and  opinions,  and  has  made
available to SRNB for inspection all reviews, correspondence  and
other  documents in the files of NVBancorp prepared by  certified
public   accountants  engaged  by  NVBancorp  and  delivered   to
NVBancorp  since  December 31, 1994.  The  financial  records  of

                               -35-
<PAGE>

NVBancorp  have been, and are being and shall be,  maintained  in
all material respects in accordance with all applicable legal and
accounting   requirements   sufficient   to   insure   that   all
transactions  reflected  therein are, in all  material  respects,
executed  in  accordance with management's  general  or  specific
authorization and recorded in conformity with generally  accepted
accounting principles at the time in effect.  The data processing
equipment,   data  transmission  equipment,  related   peripheral
equipment and software used by NVBancorp in the operation of  its
business  to  generate  and retrieve its  financial  records  are
adequate for the current needs of NVBancorp.

          g.   Tax Returns.

               (i)   NVBancorp  has  timely  filed  all  federal,
          state,  county,  local and foreign tax returns required
          to be  filed  by  it,  including,  without  limitation,
          estimated  tax, use tax,  excise tax, real property and
          personal  property tax reports and returns,  employer's
          withholding tax returns,  other withholding tax returns
          and Federal  Unemployment  Tax  Returns,  and all other
          reports or other  information  required or requested to
          be filed by NVBancorp,  and each such return, report or
          other   information  was,  when  filed,   complete  and
          accurate in all material  respects.  NVBancorp has paid
          all taxes, fees and other government charges, including
          any  interest  and  penalties  thereon,  when they have
          become due,  except  those that are being  contested in
          good faith, which contested matters have been disclosed
          to SRNB.  NVBancorp has not been  requested to give nor
          has it given any currently  effective waivers extending
          the statutory  period of  limitation  applicable to any
          tax return  required  to be filed by it for any period.
          There are no claims pending  against  NVBancorp for any
          alleged  deficiency  in the  payment of any taxes,  and
          NVBancorp  does not know of any  pending or  threatened
          audits,  investigations  or claims for unpaid  taxes or
          relating  to any  liability  in  respect  of any taxes.
          There  have  been no  events,  including  a  change  in
          ownership,  that  would  result  in a  reappraisal  and
          establishment   of  a  new  base-year  full  value  for
          purposes of  applicable  provisions  of the  California
          Constitution, of any real property owned in whole or in
          part  by  NVBancorp  or  to  the  best  of  NVBancorp's
          knowledge, of any real property leased by NVBancorp.

               (ii)  NVBancorp has heretofore delivered  to  SRNB
          copies  of  all its tax returns with respect  to  taxes
          payable  to the United States of America and the  State
          of  California for the fiscal years ended December  31,
          1998, 1997, 1996, 1995 and 1994.

               (iii) No  consent  has  been  filed   relating  to
          NVBancorp pursuant to Section 341(f) of the IRC.

          h.    Material  Adverse Change.  Except  as  heretofore
disclosed  in writing by NVBancorp to SRNB, since June 30,  1999,
there  has  been (i) no material adverse change in the  business,

                               -36-
<PAGE>

assets,  licenses, permits, franchises, results of operations  or
financial condition of NVBancorp (whether or not in the  Ordinary
Course  of  Business),  (ii) no change  in  any  of  the  assets,
licenses, permits or franchises of NVBancorp that has had or  can
reasonably be expected to have a material adverse effect  on  any
of  the  items  listed in clause (h)(i) above, (iii)  no  damage,
destruction,  or other casualty loss (whether or not  covered  by
insurance) that has had or can reasonably be expected to  have  a
material  adverse  effect on any of the items  listed  in  clause
(h)(i) above, (iv) no amendment, modification, or termination  of
any  existing, or entering into of any new, contract,  agreement,
plan, lease, license, permit or franchise that is material to the
business,  financial condition, assets, liabilities or operations
of  NVBancorp, except in the Ordinary Course of Business, and (v)
no   disposition  by  NVBancorp  of  one  or  more  assets  that,
individually  or  in  the aggregate, are material  to  NVBancorp,
except sales of assets in the Ordinary Course of Business.

          i.    No Undisclosed Liabilities.  Except for items for
which  reserves  have been established in the  unaudited  balance
sheets  of  NVBancorp  as  of June 30, 1999,  NVBancorp  has  not
incurred or discharged, and is not legally obligated with respect
to, any indebtedness, liability (including, without limitation, a
liability  arising  out  of an indemnification,  guarantee,  hold
harmless  or  similar  arrangement)  or  obligation  (accrued  or
contingent,  whether due or to become due,  and  whether  or  not
subordinated to the claims of its general creditors), other  than
as  a  result  of operations in the Ordinary Course  of  Business
after  such  date.  No agreement pursuant to which any  loans  or
other assets have been or will be sold by NVBancorp entitles  the
buyer  of  such loans or other assets, unless there is a material
breach  of  a  representation or covenant by NVBancorp  to  cause
NVBancorp  repurchase such loan or other asset or to  pursue  any
other  form  of  recourse against NVBancorp.  NVBancorp  has  not
knowingly  made or shall make any representation or  covenant  in
any  such  agreement that contained or shall contain  any  untrue
statement of a material fact or omitted or shall omit to state  a
material fact necessary in order to make the statements contained
therein,   in  light  of  the  circumstances  under  which   such
representations and/or covenants were made or shall be made,  not
misleading.

          j.   Properties and Leases.

               (i)    NVBancorp  has good and  marketable  title,
          free and clear of all liens  and  encumbrances  and the
          right of possession, subject to existing leaseholds, to
          all real  properties and good title,  free and clear of
          all liens and  encumbrances,  to all other property and
          assets,  tangible  and  intangible,  reflected  in  the
          NVBancorp  balance  sheet as of June 30,  1999  (except
          property  held as  lessee  under  leases  disclosed  in
          writing  prior to the date  hereof and except  personal
          property  sold or otherwise  disposed of since June 30,
          1999, in the Ordinary  Course of Business),  except for
          (a) liens for taxes or assessments not delinquent,  (b)
          such other liens and encumbrances and  imperfections of
          title as do not  materially  affect  the  value of such
          property as reflected in the NVBancorp balance sheet as

                               -37-
<PAGE>

          of  June  30, 1999, or as currently shown on the  books
          and  records  of NVBancorp and which do  not  interfere
          with  or impair its present and continued use,  or  (c)
          exceptions  disclosed in title reports and  preliminary
          title  reports, copies of which have been  provided  to
          SRNB.  All tangible properties of NVBancorp conform  in
          all  material respects with all applicable  ordinances,
          regulations  and  zoning laws.   To  the  knowledge  of
          NVBancorp, all tangible properties of NVBancorp are  in
          a good state of maintenance and repair and are adequate
          for  the  current business of NVBancorp.  No properties
          of   NVBancorp,   and,  to  the  best  of   NVBancorp's
          knowledge,  no  properties in which NVBancorp  holds  a
          collateral  or contingent interest or purchase  option,
          are   the   subject  of  any  pending   or   threatened
          investigation, claim or proceeding relating to the use,
          storage   or   disposal   on  such   property   of   or
          contamination  of  such  property  by  any   toxic   or
          hazardous waste material or substance.  To the best  of
          NVBancorp's knowledge, NVBancorp does not own,  possess
          or have a collateral or contingent interest or purchase
          option  in any properties or other assets which contain
          or  have  located  within or thereon any  hazardous  or
          toxic  waste material or substance unless the  location
          of  such  hazardous  or toxic waste material  or  other
          substance  or its use thereon conforms in all  material
          respects with all federal, state and local laws, rules,
          regulations   or   other  provisions   regulating   the
          discharge of materials into the environment.  As to any
          real property not owned or leased by NVBancorp and held
          as  security for a loan or in which NVBancorp otherwise
          has an interest, NVBancorp has not controlled, directed
          or  participated in the operation or management of  any
          such  real  property  or any facilities  or  enterprise
          conducted thereon, such that it has become an owner  or
          operator   of  such  real  property  under   applicable
          environmental laws.

               (ii)   All  properties  held  by  NVBancorp  under
          leases are held under  valid,  binding and  enforceable
          leases, with such exceptions as are not material and do
          not  interfere  with the  conduct  of the  business  of
          NVBancorp,  and  NVBancorp  enjoy  quiet  and  peaceful
          possession of such leased property. NVBancorp is not in
          material  default  in any  respect  under any  material
          lease, agreement or obligation regarding its properties
          to which it is a party or by which it is bound.

               (iii)  Except as disclosed to SRNB in writing, all
          of NVBancorp's  rights and obligations under the leases
          referred  to in Section  5(j)(ii)  above do not require
          the  consent  of any  other  party  to the  transaction
          contemplated   by  this   Agreement   and  the   Merger
          Agreement.  Where  required,  NVBancorp  shall  obtain,
          prior  to the  Effective  Date,  the  consent  of  such
          parties to such transactions.

                               -38-
<PAGE>

          k.     Material   Contracts.   Except   as   previously
disclosed  to  SRNB  in  writing and excluding  loans,  lines  of
credit,  loan commitments or letters of credit to which NVBancorp
is  a party, NVBancorp is not a party to or bound by any contract
or  other agreement made in the Ordinary Course of Business which
involves  aggregate future payments by or to  NVBancorp  of  more
than  Seventy-five Thousand Dollars ($75,000) and which  is  made
for  a  fixed  period expiring more than one year from  the  date
hereof, and NVBancorp is not a party to or bound by any agreement
not  made  in  the Ordinary Course of Business  which  is  to  be
performed at or after the date hereof.  Each of the contracts and
agreements disclosed to SRNB pursuant to this Section 5(k)  is  a
legal  and  binding obligation (subject to applicable bankruptcy,
insolvency and similar laws affecting creditors' rights generally
and  subject,  as to enforceability, to equitable  principles  of
general  applicability),  and  no  breach  or  default  (and   no
condition  which, with notice or passage of time, or both,  could
become a breach or default) exists with respect thereto.

          l.    Classified Loans.  Except as previously disclosed
to  SRNB  in  writing,  there are no  loans  presently  owned  by
NVBancorp  that have been classified by NVBancorp  management  or
NVBancorp  internal  policy  or  procedure,  any  outside  review
examiner,  accountant or any bank regulatory authority  as  "Non-
Accrual,"    "Watch,"   "Other   Assets   Specially   Mentioned,"
"Substandard,"   "Doubtful,"  or  "Loss"  or   classified   using
categories or words with similar import and all loans or portions
thereof  so classified have been reserved to the extent required.
NVBancorp  regularly  reviews  and appropriately  classifies  its
loans  in  accordance  with all applicable legal  and  regulatory
requirements and generally accepted banking practices.  All loans
and  investments  of  NVBancorp  are  legal,  valid  and  binding
obligations enforceable in accordance with their respective terms
and  are  not  subject to any setoffs, counterclaims or  disputes
(subject  to  applicable bankruptcy, insolvency and similar  laws
affecting  creditors'  rights  generally  and  subject,   as   to
enforceability,    to    equitable    principles    of    general
applicability),  except  as  disclosed  to  SRNB  in  writing  or
reserved  for in the unaudited balance sheet of NVBancorp  as  of
June  30,  1999,  and  were duly authorized  under  and  made  in
compliance   with   applicable  federal  and   state   laws   and
regulations.  NVBancorp has no extensions of credit, investments,
guarantees,  indemnification agreements or  commitments  for  the
same  (including without limitation commitments to issue  letters
of  credit,  to create acceptances, or to repurchase  securities,
federal funds or other assets) other than those documented on the
books and records of NVBancorp.

          m.     No  Restrictions  on  Investments.   Except  for
pledges  to  secure  public  and trust  deposits  and  repurchase
agreements  in  the  Ordinary Course of Business  and  securities
classified as "held-to-maturity" as defined under SFAS  No.  115,
none  of the investments reflected in the NVBancorp balance sheet
as  of  June  30,  1999,  and none of  the  investments  made  by
NVBancorp  since  June 30, 1999, is subject to  any  restriction,
whether  contractual or statutory, which materially  impairs  the
ability of NVBancorp to freely dispose of such investment at  any
time.

          and any and all contracts of  employment,  and has made
          available to SRNB any Board of  Directors'  minutes (or

               (ii)   All   contributions,   premiums   or  other

          and

               (iii)  NVBancorp  has disclosed in writing to SRNB

               (iv)   The Employee  Plans have been  administered
          where  required in substantial  compliance  with ERISA,
          the IRC and the terms of such Employee Plans, and there
          is no pending or threatened  litigation relating to any
          such Employee Plan; and

               (v)    Except   as  disclosed  in  the   NVBancorp

          in  the past health benefits for retired employees  and

               (vi)   Each  Employee  Plan is in full  force  and
          effect, and neither NVBancorp, NVB, nor any other party
          thereto is in material  default under any of them,  and
          there have been no claims of  default  and there are no

               (vii)  NVBancorp  has  provided  to SRNB a list of
          all  agreements  or other  understandings  pursuant  to
          which the consummation of the transactions contemplated

          or  officer  of  NVBancorp  or  NVB to  severance  pay,
          unemployment  compensation or any other payment, or (b)
          accelerate  the time of payment or vesting or  increase

          officer.

          o.    Collective Bargaining and Employment  Agreements.
Except   as  disclosed  in  the  NVBancorp  Disclosure  Schedule,
NVBancorp  has  no  union  or collective  bargaining  or  written
employment  agreements, contracts or other  agreements  with  any
labor  organization  or  with any member of  management,  or  any
management  or consultation agreement not terminable at  will  by

been requested by, or is under discussion by management with, any
group of employees, any member of management or any other person.

union seeking to organize any of such employees.

          p.   Compensation of Officers and Employees.  Except as
disclosed in the NVBancorp Disclosure Schedule, (i) no officer or
employee  of  NVBancorp  or NVB  is  receiving  aggregate  direct
remuneration at a rate exceeding  Seventy-five  Thousand  Dollars

(whether  of  severance  pay  or  otherwise)  becoming  due  from
NVBancorp to any employee of NVBancorp.

          q.   Legal Actions and Proceedings. Except as disclosed
in the NVBancorp  Disclosure  Schedule,  NVBancorp is not a party

knowledge,  there is no reasonable basis for, any legal action or
other   proceeding  or   investigation   before  any  court,  any
arbitrator of any kind or any government agency, and NVBancorp is
not subject to any potential  adverse claim, the outcome of which
could  involve the payment or receipt by  NVBancorp of any amount
in excess of Fifty Thousand Dollars ($50,000),  unless an insurer
has agreed to defend  against and pay the amount of any resulting
liability  without  reservation,  or, if any such  legal  action,
proceeding,  investigation  or claim will not involve the payment
by  NVBancorp of a monetary  amount,  which could  reasonably  be
expected to have a material  adverse  effect on  NVBancorp or its
business  or property or the  transactions  contemplated  hereby.
NVBancorp has no knowledge of any pending or threatened claims or
charges under the Community  Reinvestment  Act,  before the Equal
Employment Opportunity  Commission,  the California Department of

relations  commission  or  agency.  There  is no  labor  dispute,
strike,  slow-down  or  stoppage  pending  or, to the best of the
knowledge of NVBancorp, threatened against NVBancorp.

          Articles  of  Incorporation  or  Bylaws  of  NVBancorp,
          respectively,  or violate in any  material  respect any
          provision  of  federal  or state law or any  government

          which  NVBancorp is subject,  or  constitute a material
          default  thereunder  or result in the  creation  of any
          lien, claim,  security interest,  encumbrance,  charge,
          restriction  or  right of any  third  party of any kind
          whatsoever  upon any of the  properties  or  assets  of
          NVBancorp.

          s.    Retention  of Broker or Consultant.   No  broker,
agent,  finder,  consultant or other  party  (other  than  legal,
compliance,  loan  reviewers and accounting  advisors)  has  been
retained  by NVBancorp or is entitled to be paid based  upon  any
agreements,  arrangements or understandings made by NVBancorp  in

                               -42-
<PAGE>

connection  with  any  of the transactions contemplated  by  this
Agreement  or  the  Merger Agreement, except that  NVBancorp  has
engaged the firm of Alex Sheshunoff & Co. to act as its financial
advisor  and to render an opinion regarding the fairness  of  the
Conversion Ratio in the Merger, from a financial point  of  view,
to  NVBancorp shareholders.  NVBancorp has provided SRNB  with  a
true and accurate copy of its agreement(s) with Alex Sheshunoff &
Co.

          t.    Insurance.   NVBancorp is and continuously  since
its  inception have been, insured with reputable insurers against
all  risks normally insured against by bank holding companies and
banks, and all of the insurance policies and bonds maintained  by
NVBancorp  are  in  full force and effect, NVBancorp  is  not  in
default  thereunder and all material claims thereunder have  been
filed  in  due and timely fashion.  In the best judgment  of  the
management of NVBancorp, such insurance coverage is adequate  for
NVBancorp.   Since  December 31, 1994, there  has  not  been  any
damage to, destruction of, or loss of any assets of NVBancorp not
covered by insurance that could reasonably be expected to have  a
material   adverse  effect  the  business,  financial  condition,
properties, assets or results of operations of NVBancorp.

          u.   Loan Loss Reserves.  The allowance for loan losses
in  the NVBancorp consolidated balance sheets dated December  31,
1998  and  June  30, 1999, are, and as of the Determination  Date
will be, adequate in all material respects under the requirements
of  all  applicable  state and federal laws  and  regulations  to
provide  for  possible loan losses on outstanding loans,  net  of
recoveries.  NVBancorp has disclosed to SRNB in writing prior  to
the date hereof, and will promptly inform SRNB of the amounts  of
all loans, leases, other extensions of credit or commitments,  or
other  interest-bearing assets of NVBancorp and  NVB,  that  have
been  classified as of the date hereof or hereafter by  NVBancorp
or  NVB  management  or  NVBancorp  or  NVB  internal  policy  or
procedure,  any outside review examiner, accountant or  any  bank
regulatory  authority  as "Non-Accrual," "Watch,"  "Other  Assets
Specially  Mentioned," "Substandard," "Doubtful,"  or  "Loss"  or
classified using categories or words with similar import  in  the
case of loans (or that would have been so classified, in the case
of   other   interest-bearing  assets,  had  they  been   loans).
Notwithstanding the above, NVBancorp shall be under no obligation
to   disclose  to  SRNB  any  such  classification  by  any  bank
regulatory  authority, where such disclosure  would  violate  any
obligation of confidentiality of NVBancorp or NVB imposed by such
bank  regulatory  authority.  NVBancorp has  furnished  and  will
continue  to  furnish  to  SRNB  true  and  accurate  information
concerning  the  loan  portfolio of NVBancorp  and  NVB,  and  no
material information with respect to the loan portfolio has  been
or will be withheld from SRNB.

          v.    Transactions  With  Affiliates.   Except  in  the
Ordinary  Course of Business, NVBancorp has not extended  credit,
committed itself to extend credit, or transferred any asset to or
assumed or guaranteed any liability of the employees or directors
of NVBancorp, or to any spouse or child of any of them, or to any
of  their "affiliates" or "associates" as such terms are  defined
in  Rule 405 under the 1933 Act.  NVBancorp has not entered  into

                               -43-
<PAGE>

any  other  transactions  with  the  employees  or  directors  of
NVBancorp or any spouse or child of any of them, or any of  their
affiliates or associates, except as disclosed in writing to SRNB.
Any  such  transactions have been on terms no less  favorable  to
NVBancorp  than  those  which would  prevail  in  an  arms-length
transaction with an independent third party.  NVBancorp  has  not
violated  any applicable regulation of any government  agency  or
regulatory  authority  having  jurisdiction  over  NVBancorp   in
connection   with  any  such  transactions  described   in   this
subsection.

          w.     Risk Management Instruments.  All interest  rate
swaps,  caps,  floors,  option agreements,  futures  and  forward
contracts and other similar risk management arrangements, whether
entered  into for NVBancorp's own account, or for the account  of
one  or more of NVBancorp's subsidiaries or their customers  (all
of  which  are  listed on the NVBancorp Disclosure Schedule),  if
any,  were  entered  into  in accordance  with  prudent  business
practices  and  all  applicable  laws,  rules,  regulations   and
regulatory  policies  and  with  counterparties  believed  to  be
financially responsible at the time; and each of them constitutes
the  valid and legally binding obligation of NVBancorp or one  of
its  subsidiaries,  enforceable  in  accordance  with  its  terms
(except   as   enforceability  may  be  limited   by   applicable
bankruptcy,  insolvency, reorganization,  moratorium,  fraudulent
transfer and similar laws of general applicability relating to or
affecting creditors' rights or by general equity principles), and
are  in  full  force  and  effect.   Neither  NVBancorp  nor  its
subsidiaries,  nor  to  NVBancorp's knowledge,  any  other  party
thereto,  is in breach of any of its obligations under  any  such
agreement or arrangement.

          x.    Year  2000.   To the knowledge of NVBancorp,  the
mission  critical computer software operated by NVBancorp  and/or
any of its subsidiaries is currently capable of providing, or  is
being  adapted to provide, uninterrupted millennium functionality
to  record, store, process and present calendar dates falling  on
or  after  January 1, 2000 in substantially the same  manner  and
with   substantially  the  same  functionality  as  such  mission
critical  software records, stores, processes and  presents  such
calendar  dates falling on or before December 31, 1999.   To  the
knowledge of NVBancorp, the costs of adaptations referred  to  in
this  clause will not have a material adverse effect with respect
to  the  business and operations of NVBancorp.  Neither NVBancorp
nor any of its subsidiaries has received, and does not reasonably
expect  to  receive, any deficiency notice from  any  federal  or
California banking authority.  NVBancorp has previously disclosed
to SRNB a complete and accurate copy of its and its subsidiaries'
plan, including an estimate of anticipated associated costs,  for
addressing  the  issues  set  forth  in  all  Federal   Financial
Institutions Examination Council Interagency Statements  as  such
issues  affect  NVBancorp and/or its subsidiaries.   Between  the
date of this Agreement and the Effective Time, NVBancorp and  NVB
shall  use  commercially  reasonable and practicable  efforts  to
implement such plan.

          y.    Community Reinvestment Act Compliance.  NVBancorp
is  in  substantial compliance with the applicable provisions  of
the  Community  Reinvestment  Act of  1977  and  the  regulations
promulgated thereunder (collectively, the "CRA") and has received
a  CRA  rating of "satisfactory" from the FDIC in its most recent
examination,  and neither NVBancorp nor NVB has no  knowledge  of
the  existence  of any fact or circumstance or set  of  facts  or
circumstances  which could be reasonably expected  to  result  in
NVBancorp  failing  to  be in substantial  compliance  with  such
provisions or having its current rating lowered.

          z.    Information in NVBancorp Registration  Statement.
The information pertaining to NVBancorp which has been or will be
included  in the NVBancorp Registration Statement and  the  Joint
Proxy Statement/Prospectus, or in the Applications to be filed to
obtain  the  Government Approvals, does not and will not  contain
any untrue statement of any material fact or omit or will omit to

necessary  to  make  the  statements therein,  in  light  of  the
circumstances   under  which  they  are  made,  not   misleading;

and  results of operations of NVBancorp at the dates and for  the
periods  covered by such statements in accordance with  generally
accepted  accounting principles consistently  applied  throughout
the periods covered by such statements.  NVBancorp shall promptly
advise  SRNB  in writing if prior to the Effective  Time  of  the
Merger  NVBancorp shall obtain knowledge of any facts that  would
make   it   necessary  to  amend  or  supplement  the   NVBancorp
Registration  Statement, the Joint Proxy Statement/Prospectus  or
any  Application,  in  order to make the statements  therein  not
misleading or to comply with applicable law or regulation.

Warranties,   Covenants  and  Agreements.   Each  representation,
warranty, covenant and agreement of NVBancorp set forth  in  this
Agreement shall be deemed to be made on and as of the date hereof

such  representation  or  warranty), the  Closing  Date  and  the
Effective  Time of the Merger.  No representation or warranty  by

agreement,  schedule  or  other  document  furnished  or  to   be
furnished  in  connection with the transactions  contemplated  by

          Shares which they hold;

               (iii) the  holding  period  of  NVBancorp   Shares
          exchanged  for SRNB  Shares  will  include  the holding

          assuming  the SRNB  Shares  are  capital  assets in the
          hands of the holder thereof at the Effective Date;

               (iv)  the basis of the NVBancorp  Shares  received
          in the  exchange  will be the same as the  basis of the

          basis  attributable to fractional shares for which cash
          is received; and

               (v)   an  SRNB  shareholder  who  dissents  to the
          Merger  and  receives  cash for his or her SRNB  Shares
          will be treated as having  received a  distribution  in
          redemption  of his or her SRNB  Shares,  subject to the

          e.   Effect of Termination; Liquidated Damages.

               (i)     If this  Agreement is  terminated  for any
          reason,   the  Merger  Agreement  shall   automatically
          terminate.  Termination  of this  Agreement  shall  not
          terminate or affect the  obligations  of the parties to
          pay expenses as provided in Section 11, to maintain the
          confidentiality   of  the  each   party's   information
          obtained   pursuant   to   this   Agreement   and   the

          willful or  deliberate  failure to comply with  Section
          12.b.(viii) or Section 12.b.(xiv), which compliance was

          pay to  NVBancorp,  on demand,  the sum of Two  Million
          Dollars  ($2,000,000).  In each such  case,  the amount
          indicated  shall  be  deemed  liquidated   damages  for
          expenses  incurred  and the lost  opportunity  cost for
          time devoted to the  transactions  contemplated by this
          Agreement.

               (iii)   If SRNB terminates this Agreement pursuant
          to Section 12.b.(x), or pursuant to Section 12.b.(xiii)
          or Section 12.b.(xv) as a result of NVBancorp's willful
          or   deliberate   failure   to  comply   with   Section
          12.b.(xiii) or Section 12.b.(xv),  which compliance was
          not beyond the  reasonable  control of NVBancorp,  then
          NVBancorp shall pay to SRNB, on demand,  the sum of Two
          Million  Dollars  ($2,000,000).  In each such case, the
          amount indicated shall be deemed liquidated damages for
          expenses  incurred  and the lost  opportunity  cost for
          time devoted to the  transactions  contemplated by this
          Agreement.

other  party  (the "Indemnifying Party") written notice  of  such
claim  or  the  commencement of such action or  proceeding.   The
Indemnifying  Party  shall  have the right,  at  its  option,  to
compromise  or  defend,  by  its own  counsel,  any  such  matter
involving  the  Indemnified Party's asserted liability.   In  the
event  that  the Indemnifying Party shall undertake to compromise
or  defend any such asserted liability, it shall promptly  notify
the  Indemnified  Party  of  its intention  to  do  so,  and  the
Indemnified Party agrees to cooperate fully with the Indemnifying
Party  and its counsel in the compromise of, or defense  against,
any  such  asserted  liability.  In any event,  the  Indemnifying
Party shall have the right to participate in the defense of  such
asserted liability.

the  validity,  legality  and  enforceability  of  the  remaining
provisions  shall not, except as otherwise required  by  law,  be
affected or impaired as a result of such prohibition or ruling.

          i.    Counterparts.  This Agreement may be executed  in
several  counterparts, each of which shall be deemed an original,
but  all  of  which together shall constitute one  and  the  same
instrument.

                               -63-

     IN  WITNESS  WHEREOF, NVBancorp and SRNB  have  caused  this
Agreement  and Plan of Reorganization and Merger to be signed  by
their duly authorized officers as of the day and year first above
written.

Members of the Board of Directors
Six Rivers National Bank
402 F Street
Eureka, California  95501


Members of the Board:

         You have requested our opinion as investment bankers as to the
fairness, from a financial point of view, to the holders of the outstanding
shares of Common Stock, $5.00 par value, of Six Rivers National Bank ("SRNB") of
the Conversion Ratio, as defined in Section 2.1. of the Agreement and Plan of
Reorganization and Merger dated as of October 3, 1999 (the "Agreement"), in the
proposed merger (the "Merger") of SRNB and North Valley Bancorp ("NVBancorp").

         Hoefer & Arnett Incorporated, as part of its investment banking
business, is continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for estate, corporate and
other purposes. Hoefer & Arnett Incorporated provides a full range of financial
advisory and securities services and, in the course of its normal trading
activities, may from time to time effect transactions and hold securities, of
SRNB or NVBancorp for its own account and for the accounts of customers. We are
familiar with SRNB having acted as its financial advisor in connection with the
Agreement.

         In connection with this opinion, we have reviewed, among other things,
the Agreement; the Annual Report to Shareholders of SRNB and NVBancorp for the
years ended December 31, 1997 and 1998; the Annual Report on Form 10-K of SRNB
and NVBancorp for the years ended December 31, 1997 and 1998; certain interim
reports to shareholders and Quarterly Reports on Form 10-Q of SRNB and
NVBancorp; certain other communications from SRNB and NVBancorp to the their
respective shareholders; and certain internal financial analyses and forecasts
for SRNB and NVBancorp prepared by their respective managements including
forecasts for certain costs savings and revenue opportunities (the "Synergies")
expected to be achieved as a result of the Merger. We also have held discussions
with members of the senior management of SRNB and NVBancorp regarding the
strategic rationale for, and the potential benefits of, the Merger and the past
and current business operations, regulatory relationships, financial condition
and future prospects of their respective companies. In addition, we have
reviewed the reported price and trading activity for the shares of SRNB and
NVBancorp, compared certain financial and stock market information for SRNB and
NVBancorp with similar information for certain other companies the securities of
which are publicly traded, reviewed the financial terms of certain recent
business combinations in the commercial banking industry and performed such
other studies and analyses as we considered appropriate.

         We have relied upon the accuracy and completeness of all of the
financial and other information reviewed by us and have assumed such accuracy

                                      B-1
<PAGE>

and completeness for purposes of rendering this opinion. In that regard, we have
assumed, with your consent, that the financial forecasts, including, without
limitation, the Synergies and projections regarding under-performing and
non-performing assets and net charge-offs have been reasonably prepared on a
basis reflecting the best currently available judgments and estimates of SRNB
and NVBancorp and that such forecasts will be realized in the amounts and at the
times contemplated thereby. We are not experts in the evaluation of loan and
lease portfolios for purposes of assessing the adequacy of the allowances for
losses with respect thereto and have assumed, with your consent, that such
allowances for each of SRNB and NVBancorp are in the aggregate adequate to cover
all such losses. In addition, we have not reviewed individual credit files nor
have we made an independent evaluation or appraisal of the assets and
liabilities of SRNB, NVBancorp or any of their subsidiaries and we have not been
furnished with any such evaluation or appraisal. We also have assumed, with your
consent, that the Merger will be accounted for as a pooling of interests under
generally accepted accounting principles and that obtaining any necessary
regulatory approvals and third party consents for the Merger or otherwise will
not have a material adverse effect on SRNB, NVBancorp or the combined company
pursuant to the Merger. In addition, our opinion does not address the relative
merits of the Merger as compared to any alternative business transaction that
might be available to SRNB.

         Our advisory services and the opinion expressed herein are provided for
the information and assistance of the board of directors of SRNB in connection
with its consideration of the Merger and such opinion does not constitute a
recommendation as to how any holder of shares of SRNB should vote with respect
to such transaction.

         Based upon and subject to the foregoing and based upon such other
matters as we consider relevant, it is our opinion that as of the date hereof
the Conversion Ratio pursuant to the Agreement is fair from a financial point of
view to the holders of the outstanding shares of Common Stock of Six Rivers
National Bank.

Very truly yours,

Board of Directors
North Valley Bancorp
880 E. Cypress Avenue
Redding, California 96099-4630

Members of the Board:

         North Valley Bancorp ("NVBancorp") and Six Rivers National Bank
("SRNB") entered into an Agreement and Plan of Reorganization and Merger dated
as of October 3, 1999 (the "Agreement"), that provides, among other things, for
the exchange of all of the capital stock of SRNB for the capital stock of
NVBancorp by means of a merger of SRNB with and into NVB Interim National Bank,
a subsidiary of NVBancorp (the "Merger"). Pursuant to the Agreement, each SRNB
shareholder will receive, in exchange for each share of SRNB Common Stock, the
number of shares of NVBancorp Common Stock determined in accordance with the
conversion ratio as more fully set forth in Section 2.1 of the Agreement (the
"Conversion Ratio"). Pursuant to the Agreement, the Conversion Ratio shall equal
1.45 shares of Common Stock of NVBancorp in exchange for one share of SRNB
Common Stock provided the Average Closing Price on the Determination Date of
NVBancorp Common Stock is not less than $10.00 per share and not more than
$12.49 per share. If the Average Closing Price is not less than $12.50 per share
and is not more than $15.00 per share, the Conversion Ratio shall be 1.40 shares
of Common Stock of NVBancorp in exchange for one share of SRNB Common Stock. If
the Average Closing Price is greater than $15.00 per share, the Conversion Ratio
shall be determined in accordance with the following formula: $21.00 + .56 x
(Average Closing Price minus $15.00) divided by Average Closing Price.

         If the Average Closing Price on the Determination Date of NVBancorp
Common Stock shall be less than $10.00, NVBancorp or SRNB shall have the right
to terminate the Agreement pursuant to the terms and conditions set forth in
Section 12 of the Agreement.

         You requested Alex Sheshunoff & Co. Investment Banking's
("Sheshunoff's") opinion, as to whether the Conversion Ratio is fair from a
financial point of view to NVBancorp Common Shareholders. In connection with our
opinion, Sheshunoff has: (i) reviewed a draft copy of the Agreement; (ii)
reviewed certain publicly available financial statements and other information
of NVBancorp and SRNB, respectively; (iii) reviewed certain estimates of cost
savings prepared by NVBancorp's management arising from the transaction; (iv)
analyzed the pro forma impact of the Merger on the combined company's earnings,
book value, dividends and tangible book value per share based upon assumptions
provided by NVBancorp's management, (v) discussed NVBancorp's past and current
operations, financial condition, and prospects with its executive management;
(vi) compared NVBancorp and SRNB from a financial point of view with certain
other companies which Sheshunoff deemed to be relevant; (vi) reviewed the
financial terms, to the extent publicly available, of certain comparable merger
transactions, (vii) reviewed reported market prices and historical trading
activity of NVBancorp's common stock and certain analysts' projections of
NVBancorp's potential 1999 and 2000 earnings per share; (viii) performed such
other analyses and examinations as Sheshunoff has deemed appropriate.

                                      C-1
<PAGE>


         Sheshunoff assumed and relied upon without independent verification the
accuracy and completeness of the information supplied or otherwise made
available to us by NVBancorp. Sheshunoff did not make an independent evaluation
of the assets or liabilities of SRNB nor NVBancorp. Sheshunoff did not perform
any due diligence review of either SRNB or NVBancorp and did not visit either
institution. Sheshunoff assumed that NVBancorp's budgets and financial forecasts
were reasonably prepared and reflect the best currently available estimates and
judgments of NVBancorp's management, as to its future financial performance.
Sheshunoff assumed such forecasts and projections will be realized in the
amounts and at the times contemplated thereby. In that regard, Sheshunoff
assumed, with NVBancorp's consent, that the financial forecasts, including,
without limitation, projected cost savings and projections regarding
under-performing and non-performing assets and net charge-offs had been
reasonably prepared on a basis reflecting the best then available judgments and
estimates of NVBancorp and SRNB and that such forecasts will be realized in the
amounts and at the times contemplated thereby. Sheshunoff makes no
representations or warranty that the financial forecasts and projections
prepared by NVBancorp will be realized in the amounts and at the times
forecasted and projected. Sheshunoff assumed that obtaining any necessary
regulatory approvals and third party consents for the Merger will not have an
adverse effect on NVBancorp, SRNB or the combined company. Sheshunoff has
further assumed that the Merger will be accounted for as a pooling-of-interests
under generally accepted accounting principals and that it will qualify as a
tax-free reorganization for U.S.
federal income tax purposes.

         Sheshunoff is not an expert in the evaluation of loan portfolios for
the purpose of assessing the adequacy of the allowance for losses, and assumed
based upon NVBancorp's management representations that such allowances, for each
of the companies, are in the aggregate, adequate to cover such losses.
Sheshunoff did not review any individual credit files nor made any independent
evaluation, appraisal or physical inspection of the assets or individual
properties of SRNB or NVBancorp.

         Sheshunoff did not assess, nor was it furnished with any assessments,
of SRNB's compliance with operational and regulatory standards for its data
processing and other systems compliance with the Year 2000 capability. If SRNB
is not able to bring its operations into compliance with the year 2000
capability, the fairness of the Conversion Ratio may be adversely impacted.

         Sheshunoff's opinion is necessarily based on economic, market and other
conditions in effect on, and the information made available to it, as of the
date hereof. Events occurring after the date hereof could materially affect the
assumptions used in preparing this opinion. Sheshunoff assumed that there are no
material changes in SRNB's or NVBancorp's assets, financial condition, results
of operations, business or prospects since the respective dates of their last
financial statements reviewed by it, and that off-balance sheet activities will
not materially impact the future financial position or results of operation of
SRNB and NVBancorp. Sheshunoff assumed the Merger will be completed as set forth
in the Agreement and that no material changes will be made in the Agreement nor
will restrictions be imposed by regulatory or other parties on the terms of the
Agreement.

         Sheshunoff's opinion is limited to the fairness, from a financial point
of view, to the holders of NVBancorp's Common Stock of the Conversion Ratio.
Sheshunoff does not address NVBancorp's underlying business decision to
undertake the Merger. This letter, and the opinion expressed herein, do not
constitute a recommendation to any shareholder as to how any shareholder should
vote in the shareholder's vote on the Merger or the Agreement. This letter is
for the information of the board of directors of NVBancorp and may not be used

                                      C-2
<PAGE>


for any other purpose without Sheshunoff's prior written consent, except that
this opinion may be included in its entirety in any filing made by NVBancorp or
SRNB with the Securities and Exchange Commission with respect to the Merger.

         Based upon and subject to the foregoing, it is Sheshunoff's opinion
that, as of the date hereof, the Conversion Ratio is fair from a financial point
of view to NVBancorp's shareholders.



Very truly yours,

                                     ANNEX D

         CHAPTER 13. DISSENTERS' RIGHTS.

         SS.1300. REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES;
CORPORATE PURCHASE AT FAIR MARKET VALUE; DEFINITIONS--

         (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.

         (b) As used in this chapter, "dissenting shares" means shares which
come within all of the following descriptions:

                  (1) Which were not immediately prior to the reorganization or
short-form merger either (A) listed on any national securities exchange
certified by the Commissioner of Corporations under subdivision (o) of Section
25100 or (B) listed on the list of OTC margin stocks issued by the Board of
Governors of the Federal Reserve System, and the notice of meeting of
shareholders to act upon the reorganization summarizes this section and Sections
1301, 1302, 1303 and 1304; provided, however, that this provision does not apply
to any shares with respect to which there exists any restriction on transfer
imposed by the corporation or by any law or regulation; and provided, further,
that this provision does not apply to any class of shares described in
subparagraph (A) or (B) if demands for payment are filed with respect to 5
percent or more of the outstanding shares of that class.

                  (2) Which were outstanding on the date for the determination
of shareholders entitled to vote on their organization and (A) were not voted in
favor of the reorganization or, (B) if described in subparagraph (A) or (B) of
paragraph (1) (without regard to the provisos in that paragraph), were voted
against the reorganization, or which were held of record on the effective date
of a short-form merger; provided, however, that subparagraph (A) rather than
subparagraph (B) of this paragraph applies in any case where the approval
required by Section 1201 is sought by written consent rather than at a meeting.

                  (3) Which the dissenting shareholder has demanded that the
corporation purchase at their fair market value, in accordance with Section
1301.

                  (4) Which the dissenting shareholder has submitted for
endorsement, in accordance with Section 1302.

         (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

         SS.1301. NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS;
DEMAND FOR PURCHASE; TIME; CONTENTS--

         (a) If, in the case of a reorganization, any shareholders of a
corporation have a right under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation to

                                      D-1
<PAGE>


purchase their shares for cash, such corporation shall mail to each such
shareholder a notice of the approval of the reorganization by its outstanding
shares (Section 152) within 10 days after the date of such approval, accompanied
by a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of
the price determined by the corporation to represent the fair market value of
the dissenting shares, and a brief description of the procedure to be followed
if the shareholder desires to exercise the shareholder's right under such
sections. The statement of price constitutes an offer by the corporation to
purchase at the price stated any dissenting shares as defined in subdivision (b)
of Section 1300, unless they lose their status as dissenting shares under
Section 1309.

         (b) Any shareholder who has a right to require the corporation to
purchase the shareholder's shares for cash under Section 1300, subject to
compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who
desires the corporation to purchase such shares shall make written demand upon
the corporation for the purchase of such shares and payment to the shareholder
in cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' special meeting to vote
upon the reorganization, or (2) in any other case within 30 days after the date
on which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

         (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

         SS.1302. SUBMISSION OF SHARE CERTIFICATES FOR ENDORSEMENT;
UNCERTIFICATED SECURITIES--

         Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.

         SS.1303. PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR
MARKET VALUE; FILING; TIME OF PAYMENT--

         (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

                                      D-2
<PAGE>


         (b) Subject to the provisions of Section 1306, payment of the fair
market value of dissenting shares shall be made within 30 days after the amount
thereof has been agreed or within 30 days after any statutory or contractual
conditions to the reorganization are satisfied, whichever is later, and in the
case of certificated securities, subject to surrender of the certificates
therefor, unless provided otherwise by agreement.

         SS.1304. ACTION TO DETERMINE WHETHER SHARES ARE DISSENTING SHARES OR
FAIR MARKET VALUE; LIMITATION; JOINDER; CONSOLIDATIOn; DETERMINATION OF ISSUES;
APPOINTMENT OF APPRAISERS--

         (a) If the corporation denies that the shares are dissenting shares, or
the corporation and the shareholder fail to agree upon the fair market values of
the shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

         (b) Two or more dissenting shareholders may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.

         (c) On the trial of the action, the court shall determine the issues.
If the status of the shares as dissenting shares is in issue, the court shall
first determine that issue. If the fair market value of the dissenting shares is
in issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

         SS.1305. REPORT OF APPRAISERS; CONFIRMATION; DETERMINATION BY COURT;
JUDGMENT; PAYMENT; APPEAL; COSTS--

         (a) If the court appoints an appraiser or appraisers, they shall
proceed forthwith to determine the fair market value per share. Within the time
fixed by the court, the appraisers, or a majority of them, shall make and file a
report in the office of the clerk of the court. Thereupon, on the motion of any
party, the report shall be submitted to the court and considered on such
evidence as the court considers relevant. If the court finds the report
reasonable, the court may confirm it.

         (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

         (c) Subject to the provisions of Section 1306, judgment shall be
rendered against the corporation for payment of an amount equal to the fair
market value of each dissenting share multiplied by the number of dissenting
shares which any dissenting shareholder who is a party, or who has intervened,
is entitled to require the corporation to purchase, with interest thereon at the
legal rate from the date on which judgment was entered.

         (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

                                      D-3
<PAGE>


         (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

         SS.1306. PREVENTION OF IMMEDIATE PAYMENT; STATUS AS CREDITORS;
INTEREST--

         To the extent that the provisions of Chapter 5 prevent the payment to
any holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

         SS.1307. DIVIDENDS ON DISSENTING SHARES--

         Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.

         SS.1308. RIGHTS OF DISSENTING SHAREHOLDERS PENDING VALUATION;
WITHDRAWAL OF DEMAND FOR PAYMENT--

         Except as expressly limited in this chapter, holders of dissenting
shares continue to have all the rights and privileges incident to their shares,
until the fair market value of their shares is agreed upon or determined. A
dissenting shareholder may not withdraw a demand for payment unless the
corporation consents thereto.

         SS.1309. TERMINATION OF DISSENTING SHARE AND SHAREHOLDER STATUS--

         Dissenting shares lose their status as dissenting shares and the
holders thereof cease to be dissenting shareholders and cease to be entitled to
require the corporation to purchase their shares upon the happening of any of
the following:

         (a) The corporation abandons the reorganization. Upon abandonment of
the reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

         (b) The shares are transferred prior to their submission for
endorsement in accordance with Section 1302 or are surrendered for conversion
into shares of another class in accordance with the articles.

         (c) The dissenting shareholder and the corporation do not agree upon
the status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

                                      D-4
<PAGE>

         (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

         SS.1310. SUSPENSION Of RIGHT TO COMPENSATION OR VALUATION PROCEEDINGS;
LITIGATION OF SHAREHOLDERS' APPROVAL--

         If litigation is instituted to test the sufficiency or regularity of
the votes of the shareholders in authorizing a reorganization, any proceedings
under Sections 1304 and 1305 shall be suspended until final determination of
such litigation.

         SS.1311. EXEMPT SHARES--

         This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

         SS.1312. RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR
RESCIND MERGER OR REORGANIZATION; RESTRAINING ORDER or INJUNCTION; CONDITIONS--

         (a) No shareholder of a corporation who has a right under this chapter
to demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

         (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.

         (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

TITLE 12, UNITED STATES CODE, SECTION 215A (B), (C) AND (D):

         DISSENTING SHAREHOLDERS

         (b) If a merger shall be voted for at the called meetings by the
necessary majorities of the shareholders of each association or State bank
participating in the plan of merger, and thereafter the merger shall be approved
by the Comptroller, any shareholder of any association or State bank to be
merged into the receiving association who has voted against such merger at the
meeting of the association or bank of which he is a stockholder, or has given
notice in writing at or prior to such meeting to the presiding officer that he
dissents from the plan of merger, shall be entitled to receive the value of the
shares so held by him when such merger shall be approved by the Comptroller upon
written request made to the receiving association at any time before thirty days
after the date of consummation of the merger, accompanied by the surrender of
his stock certificates.

         VALUATION OF SHARES

         (c) The value of the shares of any dissenting shareholder shall be
ascertained, as of the effective date of the merger, by an appraisal made by a
committee of three persons, composed of (1) one selected by the vote of the
holders of the majority of the stock, the owners of which are entitled to
payment in cash; (2) one selected by the directors of the receiving association;
and (3) one selected by the two so selected. The valuation agreed upon by any
two of the three appraisers shall govern. If the value so fixed shall not be
satisfactory to any dissenting shareholder who has requested payment, that
shareholder may, within five days after being notified of the appraised value of
his shares, appeal to the Comptroller, who shall cause a reappraisal to be made
which shall be final and binding as to the value of the shares of the appellant.

         APPLICATION TO SHAREHOLDERS OF MERGING ASSOCIATIONS; APPRAISAL BY
         COMPTROLLER; EXPENSES OF RECEIVING ASSOCIATION; SALE AND RESALE OF
         SHARES; STATE APPRAISAL AND MERGER LAW

         (d) If, within ninety days from the date of consummation of the merger,
for any reason one or more of the appraisers is not selected as herein provided,
or the appraisers fail to determine the value of such shares, the Comptroller
shall upon written request of any interested party cause an appraisal to be made
which shall be final and binding on all parties. The expenses of the Comptroller
in making the reappraisal or the appraisal, as the case may be, shall be paid by
the receiving association. The value of the shares ascertained shall be promptly
paid to the dissenting shareholders by the receiving association. The shares of
stock of the receiving association which would have been delivered to such
dissenting shareholders had they not requested payment shall be sold by the
receiving association at an advertised public auction, and the receiving
association shall have the right to purchase any of such shares at such public
auction, if it is the highest bidder therefor, for the purpose of reselling such
shares within thirty days thereafter to such person or persons and at such price
not less than par as its board of directors by resolution may determine. If the
shares are sold at public auction at a price greater than the amount paid to the
dissenting shareholders, the excess in such sale price shall be paid to such
dissenting shareholders. The appraisal of such shares of stock in any State bank
shall be determined in the manner prescribed by the law of the State in such
cases, rather than as provided in this section, if such provision is made in the
State law; and no such merger shall be in contravention of the law of the State
under which such bank is incorporated. The provisions of this subsection shall
apply only to shareholders of (and stock owned by them in) a bank or association
being merged into the receiving association.

  Banking Circular

  BC-259

1992 OCC CB LEXIS 21

  March 5, 1992

[*1]
 Stock Appraisals

To:    Chief Executive Officers of National Banks, Deputy Comptrollers
       (District), Department and Division Heads, and Examining Personnel

PURPOSE

This banking circular informs all national banks of the valuation methods used
by the Office of the Comptroller of the Currency (OCC) to estimate the value of
a bank's shares when requested to do so by a shareholder dissenting to the
conversion, merger, or consolidation of its bank. The results of appraisals
performed by the OCC between January 1, 1985 and September 30, 1991 are
summarized.

References: 12 U.S.C. 214A, 215 and 215a; 12 CFR 11.590 (Item 2)

BACKGROUND

Under 12 U.S.C. SECTION 214A, a shareholder dissenting from a conversion,
consolidation, or merger involving a national bank is entitled to receive the
value of his or her shares from the resulting bank. A valuation of the shares
shall be made by a committee of three appraisers (a representative of the
dissenting shareholder, a representative of the resulting bank, and a third
appraiser selected by the other two). If the committee is formed and renders an
appraisal that is acceptable to the dissenting shareholder, the process is
complete and [*2] the appraised value of the shares is paid to the dissenting
shareholder by the resulting bank. If, for any reason, the committee is not
formed or if it renders an appraisal that is not acceptable to the dissenting
shareholder, an interested party may request an appraisal by the OCC. 12 U.S.C.
SECTION 215 provides these appraisal rights to any shareholder dissenting to a
consolidation. Any dissenting shareholder of a target bank in a merger is also
entitled to these appraisal rights pursuant to 12 U.S.C. SECTION 215A.

The above provides only a general overview of the appraisal process. The
specific requirements of the process are set forth in the statutes themselves.

METHODS OF VALUATION USED

Through its appraisal process, the OCC attempts to arrive at a fair estimate of
the value of a bank's shares. After reviewing the particular facts in each case
and the available information on a bank's shares, the OCC selects an appropriate
valuation method, or combination of methods, to determine a reasonable estimate
of the shares' value.

Market Value

The OCC uses various methods to establish the market value of shares being
appraised. If sufficient trading in the shares [*3] exists and the prices are
available from direct quotes from the Wall Street Journal or a market-maker,
those quotes are considered in determining the market value. If no market value
is readily available, or if the market value available is not well established,
the OCC may use other methods of estimating market value, such as the investment
value and adjusted book value methods.

                                      E-2
<PAGE>

Investment Value

Investment value requires an assessment of the value to investors of a share in
the future earnings of the target bank. Investment value is estimated by
applying an average price/earnings ratio of banks with similar earnings
potential to the earnings capacity of the target bank.

The peer group selection is based on location, size, and earnings patterns. If
the state in which the subject bank is located provides a sufficient number of
comparable banks using location, size and earnings patterns as the criteria for
selection, the price/earnings ratios assigned to the banks are applied to the
earnings per share estimated for the subject bank. In order to select a
reasonable peer group when there are too few comparable independent banks in a
location that is comparable to that [*4] of the subject bank, the pool of banks
from which a peer group is selected is broadened by including one-bank holding
company banks in a comparable location, and/or by selecting banks in less
comparable locations, including adjacent states, that have earnings patterns
similar to the subject bank.

Adjusted Book Value

The OCC also uses an "adjusted book value" method for estimating value.
Historically, the OCC has not placed any weight on the bank's "unadjusted book
value", since that value is based on historical acquisition costs of the bank's
assets, and does not reflect investors' perceptions of the value of the bank as
an ongoing concern. Adjusted book value is calculated by multiplying the book
value of the target bank's assets per share times the average market price to
book value ratio of comparable banking organizations. The average market price
to book value ratio measures the premium or discount to book value, which
investors attribute to shares of similarly situated banking organizations.

Both the investment value method and the adjusted book value method present
appraised values which are based on the target bank's value as a going concern.
These techniques [*5] provide estimates of the market value of the shares of the
subject bank.

OVERALL VALUATION

The OCC may use more than one of the above-described methods in deriving the
value of shares of stock. If more than one method is used, varying weights may
be applied in reaching an overall valuation. The weight given to the value by a
particular valuation method is based on how accurately the given method is
believed to represent market value. For example, the OCC may give more weight to
a market value representing infrequent trading by shareholders than to the value
derived from the investment value method when the subject bank's earnings trend
is so irregular that it is considered to be a poor predictor of future earnings.

PURCHASE PREMIUMS

For mergers and consolidations, the OCC recognizes that purchase premiums do
exist and may, in some instances, be paid in the purchase of small blocks of
shares. However, the payment of purchase premiums depends entirely on the
acquisition or control plans of the purchasers, and such payments are not
regular or predictable elements of market value. Consequently, the OCC's
valuation methods do not include consideration of purchase premiums [*6] in
arriving at the value of shares.

STATISTICAL DATA

The chart below lists the results of appraisals the OCC performed between
January 1, 1985 and September 30, 1991. The OCC provides statistical data on
book value and price/earnings ratios for comparative purposes, but does not
necessarily rely on such data in determining the value of the banks' shares.
Dissenting shareholders should not view these statistics as determinative for
future appraisals.

In connection with disclosures given to shareholders under 12 CFR 11.590 (Item
2), banks may provide shareholders a copy of this banking circular or disclose
the information in the banking circular, including the past results of OCC
appraisals. If the bank discloses the past results of the OCC appraisals, it
should advise shareholders that: (1) the OCC did not rely on all the information
set forth in the chart in performing each appraisal; and, (2) the OCC's past
appraisals are not necessarily determinative of its future appraisals of a
particular bank's shares.

TEXT OF PROPOSED AMENDMENTS TO RESTATED ARTICLES OF INCORPORATION AND BYLAWS
CONCERNING THE CLASSIFICATION OF THE BOARD OF DIRECTORS

         The Restated Articles of Incorporation of NVBancorp shall be amended by
adding thereto a new Article Sixth which shall read as set forth below:

         Sixth:  CLASSIFIED BOARD OF DIRECTORS.

         (a)      The number of directors which shall constitute the whole board
                  of directors of this corporation shall be specified in the
                  bylaws of the corporation.

         (b)      In the event that the authorized number of directors shall be
                  fixed at nine (9) or more, the board of directors shall be
                  divided into three classes: Class I, Class II and Class III,
                  each consisting of a number of directors equal as nearly as
                  practicable to one-third the total number of directors.
                  Directors in Class I shall initially serve for a term expiring
                  at the 2001 annual meeting of shareholders, directors in Class
                  II shall initially serve for a term expiring at the 2002
                  annual meeting of shareholders, and directors in Class III
                  shall initially serve for a term expiring at the 2003 annual
                  meeting of shareholders. Thereafter, each director shall serve
                  for a term ending at the third annual shareholders meeting
                  following the annual meeting at which such director was
                  elected. In the event that the authorized number of directors
                  shall be fixed with at least six (6) but less than nine (9),
                  the board of directors shall be divided into two classes,
                  designated Class I and Class II, each consisting of one-half
                  of the directors or as close an approximation as possible. At
                  each annual meeting, each of the successors to the directors
                  of the class whose term shall have expired at such annual
                  meeting shall be elected for a term running until the second
                  annual meeting next succeeding his or her election and until
                  his or her successor shall have been duly elected and
                  qualified. The foregoing notwithstanding, each director shall
                  serve until his or her successor shall have been duly elected
                  and qualified, unless he or she shall resign, die, become
                  disqualified or disabled, or shall otherwise be removed.

         (c)      At each annual election, the directors chosen to succeed those
                  whose terms then expire shall be identified as being of the
                  same class as the directors they succeed, unless, by reason of
                  any intervening changes in the authorized number of directors,
                  the board of directors shall designate one or more
                  directorships whose term then expires as directorships of
                  another class in order more nearly to achieve equality in the
                  number of directors among the classes. When the board of
                  directors fills a vacancy resulting from the resignation,
                  death, disqualification or removal of a director, the director
                  chosen to fill that vacancy shall be of the same class as the
                  director he or she succeeds, unless, by reason of any previous
                  changes in the authorized number of directors, the board of
                  directors shall designate the vacant directorship as a
                  directorship of another class in order more nearly to achieve
                  equality in the number of directors among the classes.

         (d)      Notwithstanding the rule that the classes shall be as nearly
                  equal in number of directors as possible, in the event of any
                  change in the authorized number of directors, each director
                  then continuing to serve as such will nevertheless continue as
                  a director of the class of which he or she is a member, until
                  the expiration of his current term or his or her earlier
                  resignation, death, disqualification or removal. If any newly

                                      F-1
<PAGE>

                  created directorship or vacancy on the board of directors,
                  consistent with the rule that the three classes shall be as
                  nearly equal in number of directors as possible, may be
                  allocated to one or two or more classes, the board of
                  directors shall allocate it to that of the available class
                  whose term of office is due to expire at the earliest date
                  following such allocation.

Section 16 of Article III of the NVBancorp bylaws shall be amended in its
entirety to read as follows:

         Section 16. Election and Term of Office. The directors shall be elected
annually by the shareholders at the annual meeting of the shareholders;
provided, that if for any reason, the annual meeting or an adjournment thereof
is not held or the directors are not elected thereat, then the directors may be
elected at any special meeting of the shareholders called and held for that
purpose. The term of office of the directors shall, except as provided in
Section 17, begin immediately after their election and shall continue until
their respective successors are elected and qualified. In the event that the
authorized number of directors shall be fixed at nine (9) or more, the board of
directors shall be divided into three classes, designated Class I, Class II and
Class III. Each class shall consist of one-third of the directors or as close an
approximation as possible. The initial term of office of the directors of Class
I shall expire at the annual meeting to be held during fiscal year 2001, the
initial term of office of the directors of Class II shall expire at the annual
meeting to be held during fiscal year 2002 and the initial term of office of the
directors of Class III shall expire at the annual meeting to be held during
fiscal year 2003. At each annual meeting, commencing with the annual meeting to
be held during fiscal year 2001, each of the successors to the directors of the
class whose term shall have expired at such annual meeting shall be elected for
a term running until the third annual meeting next succeeding his or her
election until his or her successor shall have been duly elected and qualified.
In the event that the authorized number of directors shall be fixed with at
least six (6) but less than nine (9), the board of directors shall be divided
into two classes, designated Class I and Class II. Each class shall consist of
one-half of the directors or as close an approximation as possible. At each
annual meeting, each of the successors to the directors of the class whose term
shall have expired at such annual meeting shall be elected for a term running
until the second annual meeting next succeeding his or her election and until
his or her successor shall have been duly elected and qualified. Notwithstanding
the rule that the classes shall be as nearly equal in number of directors as
possible, in the event of any change in the authorized number of directors, each
director then continuing to serve as such shall nevertheless continue as a
director of the class of which he or she is a member until the expiration of his
or her current term, or his or her prior death, resignation or removal. At such
annual election, the directors chosen to succeed those whose terms then expire
shall be of the same class as the directors they succeed, unless, by reason of
any intervening changes in the authorized number of directors, the board of
directors shall designate one or more directorships whose term then expires as
directorships of another class in order more nearly to achieve equality of
number of directors among the classes.

         This Section 16 may be amended or repealed only by approval of the
board of directors and the outstanding shares (as defined in Section 152 of the
California General Corporation Law) voting as a single class, notwithstanding
Section 903 of the California General Corporation Law.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 317 of the California Corporations Code authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors,
officers, employees and other agents of the corporation ("Agents") in terms
sufficiently broad to permit indemnification under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act of 1933, as amended.

         Article Fifth of the Registrant's articles of incorporation, as
amended, authorizes the Registrant to indemnify its Agents, through bylaw
provisions, agreements, votes of shareholders or disinterested directors or
otherwise, in excess of the indemnification otherwise permitted by Section 317
of the California Corporations Code, subject to the applicable limits set forth
in Section 204 of the California Corporations Code with respect to actions for
breach of duty to the Registrant and its shareholders. Section 47 of Article V
of the Registrant's bylaws provides for mandatory indemnification of each
director of the Registrant except as prohibited by law.

         The Registrant maintains a directors' and officers' liability insurance
policy that indemnifies the Registrant's directors and officers against certain
losses in connection with claims made against them for certain wrongful acts. In
addition, the Registrant has entered into separate indemnification agreements
with its directors and officers that require the Registrant, among other things,
(i) to maintain directors' and officers' insurance in reasonable amounts in
favor of those individuals, and (ii) to indemnify them against certain
liabilities that may arise by reason of their status or service as Agents of the
Registrant to the fullest extent permitted by California law.

ITEM 22.  UNDERTAKINGS

         (1) The undersigned registrant hereby undertakes: (a) 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 of 1933, as amended; (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 the volume of securities offered (if the
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
offering range may be reflected in the form of prospectus filed with the
Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate,
the changes in volume and price represent no more than a 20% 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, as amended, each
such post-effective amendment shall be deemed to be a new registration statement
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 thereof; (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.

         (2) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the registrant's annual report pursuant to section 13(a) or section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
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 thereof.

         (3) The undersigned registrant hereby undertakes as follows: that prior
to any public re-offering of the securities registered hereunder through use of
a prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such re-offering prospectus will the contain information
called for by the applicable registration form with respect to re-offerings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

<PAGE>


         (4) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (3) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Securities Act of 1933, as amended,
and is used in connection with an offering of securities subject to Rule 415,
will be filed as a part of an amendment to the registration statement and will
not be used until such amendment is effective, and that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
such post-effective amendment shall be deemed to be a new registration statement
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 thereof.

         (5) Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended, 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 Securities Act of 1933, as amended, 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 settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933, as amended, and will be
governed by the final adjudication of such issue.

         (6) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         (7) The undersigned registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, as amended,
the registrant has duly caused the Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of Redding,
State of California, on the 20TH day of December, 1999.

         Re:      North Valley Bancorp -- Registration Statement on Form S-4



Ladies and Gentlemen:

         With reference to the Registration Statement on Form S-4 filed by North
Valley Bancorp, a California corporation ("NVBancorp"), with the Securities and
Exchange Commission in connection with the registration under the Securities Act
of 1933, as amended, of 1,644,238 shares of NVBancorp Common Stock, no par value
per share (the "Shares"), to be issued in connection with the merger
contemplated by the Agreement and Plan of Reorganization and Merger, dated as of
October 3, 1999 (the "Agreement"), among Six Rivers National Bank, a national
banking association organized under the laws of the United States, and NVB
Interim National Bank, a national banking association to be formed at the
direction of NVBancorp, which Agreement is described therein and filed as an
exhibit thereto:

         We are of the opinion that the Shares have been duly authorized and,
when issued in accordance with the Agreement, will be legally issued, fully paid
and nonassessable. We hereby consent to the filing of this opinion as Exhibit
5.1 to the Registration Statement and the use of our name under the caption
"Legal Matters" in the Registration Statement and in the Joint Proxy
Statement/Prospectus included therein.

Very truly yours,

__________________, 2000               FORM OF OPINION TO BE RENDERED AT CLOSING

North Valley Bancorp
880  E. Cypress Avenue
Redding, California 96002


Six Rivers National Bank
401 F Street
Eureka, California 95501

                  MERGER OF NVB INTERIM BANK INTO SIX RIVERS NATIONAL BANK

Ladies and Gentlemen:

         You have asked for our opinion as to certain federal and California
income tax consequences of the proposed reorganization transaction that will
result in the merger of Six Rivers National Bank, a national banking association
("SRNB") with and into NVB Interim Bank, an interim national banking association
("Interim Bank") and a wholly-owned subsidiary of North Valley Bancorp, a
California corporation ("NVBancorp"), pursuant to the Agreement and Plan of
Reorganization and Merger dated as of October 3, 1999 (the "Agreement"). This
opinion is delivered to you pursuant to Sections 7.j and 8.j of the Agreement.
Capitalized terms used in this letter without definition have the respective
meanings given them in the Agreement.

         The Agreement provides that at the Effective Time of the Merger, SRNB
will be merged with and into Interim Bank, with Interim Bank as the surviving
corporation. In the Merger, each share of SRNB common stock will be exchanged
for the right to receive a specified number of shares of NVBancorp common stock.
No fractional shares of NVBancorp common stock will be issued in the Merger, but
SRNB shareholders who would otherwise be entitled to receive fractional shares
will receive cash in lieu thereof.
SRNB has only common stock outstanding.

         In rendering the opinions expressed in this letter, we have assumed
that the transactions described in the Agreement will be carried out in all
respects as provided therein. In addition, we have examined and are relying upon
(without any independent investigation or review) the truth, correctness and
completeness at all relevant times of the statements, covenants, representations
and warranties contained in the Agreement, letters dated __________ delivered to
us by NVBancorp and SRNB (the "Tax Representation Letters"), the Proxy
Statement/Prospectus dated ___________ delivered to SRNB shareholders in
connection with the solicitation of proxies for the SRNB vote on the Merger (the
"Proxy Statement/Prospectus"), and such other instruments and documents as we
have deemed necessary.

         Based upon our understanding of the transaction as described above and
the above information, representations and assumptions, and upon existing
statutes, regulations, court decisions and published rulings of the Internal
Revenue Service, it is our opinion that, for purposes of federal income tax law
and California income and franchise tax law:

<PAGE>


         1. The merger of SRNB with and into Interim Bank and the issuance of
NVBancorp common stock in the transaction as described in the Agreement will
qualify as a reorganization under Sections 368(a)(1)(A) and 368(a)(2)(D) of the
Code.

         2. The Merger will not result in the recognition of gain or loss by
NVBancorp or SRNB.

         3. No gain or loss will be recognized by holders of SRNB stock on the
exchange of SRNB stock for NVBancorp common stock, except to the extent gain is
recognized with respect to cash received in lieu of fractional shares.

         4. The holding period of NVBancorp stock received in exchange for SRNB
stock (including any fractional share prior to its conversion into cash) will
include the holding period of the SRNB stock for which it is exchanged, assuming
that the shares of SRNB stock are capital assets in the hands of the holder at
the Effective Time of the Merger.

         5. The aggregate adjusted tax basis of the shares of NVBancorp stock
received by an SRNB shareholder in the Merger (including any fractional share
prior to its conversion into cash) will be the same as the aggregate adjusted
tax basis of the SRNB shares surrendered in exchange therefor.

         6. An SRNB shareholder who dissents to the Merger and receives cash for
his or her SRNB stock will be treated as having received a distribution in
redemption of his or her SRNB stock, subject to the provisions and limitations
of Section 302 of the Internal Revenue Code of 1986, as amended.

         We hereby consent to the filing of this opinion as an exhibit to the
Proxy Statement/Prospectus and the reference to the name of our firm therein and
under the caption "Certain Federal Income Tax Consequences."

                                    Very truly yours,
