Dear Shareholder:

then and we expect to complete the Merger during December. Regulatory
applications have been filed and we anticipate approvals soon. One of the
remaining steps is to secure approval of the Merger from our shareholders. You
will find enclosed a Joint Proxy Statement which gives you information
concerning the proposed Merger. I urge you to read it carefully.

        Our special shareholders' meeting will be held on ________, November
____, 2000. I hope you will be able to attend. Whether you can attend or not,
the Board of Directors request that you complete and return the Revocable Proxy
included in this package, in the envelope provided.

        "What makes this merger of equals so unique is how well each company
complements the other. We both are extremely strong organizations in adjacent
markets, and share a firm commitment to providing quality service to our
customers. Once the transaction is approved, I believe we will be better
positioned for additional growth than any other financial institution in the
Northwest. Our partnership will not only carry on past successes, but will forge
new and exciting ground as we expand our product line and services throughout
the state."

                 INITIAL QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:      Who are the parties to the Merger?

A:      UMPQUA HOLDINGS CORPORATION is a financial holding company which
        operates two subsidiaries: South Umpqua Bank with $411 million in assets
        and office locations in Multnomah, Douglas, Lane and Marion Counties;
        and Strand, Atkinson, Williams & York, Inc., the second largest
        Oregon-based full service retail investment firm, with offices in
        Portland, Salem, Eugene, Roseburg and Medford. Umpqua's stock trades on
        the Nasdaq National Market under the symbol "UMPQ." See "INFORMATION
        ABOUT UMPQUA."

        VRB BANCORP is a bank holding company with assets of $330 million. VRB
        is the parent company of Valley of the Rogue Bank. Formed in 1968,
        Valley of the Rogue Bank is the oldest independent community bank in
        southern Oregon. VRB operates 13 banking offices from Ashland to Grants
        Pass, Oregon along the southern Oregon I-5 corridor. VRB's stock trades
        on the Nasdaq National Market under the symbol "VRBA." See "INFORMATION
        ABOUT VRB."

Q:      What is the effect of the Merger?

A:      If the Merger occurs, VRB will merge with Umpqua and Valley of the Rogue
        Bank will merge with South Umpqua Bank operating under the new name of
        "Umpqua Bank."

Q:      Why was the "Umpqua Bank" name chosen?


                                       5
<PAGE>   12
A:      Management of both companies believe that the use of the Umpqua Bank
        name together with the stylized tree and river logo will give the
        combined bank a name synonymous with the Pacific Northwest, one
        currently displayed and recognized in all major Oregon markets as well
        as the largest Oregon-based ATM network and a name unique and
        innovative, differentiating it from other community banks with generic,
        traditional names.

Q:      What will VRB stockholders receive in the Merger?

A:      Shareholders of VRB will receive 0.8135 shares of Umpqua stock for each
        share of VRB stock held (the "Exchange Ratio") and cash in lieu of any
        fractional share. The Exchange Ratio could increase to as high as 0.8500
        shares of Umpqua stock if at a specified time prior to Closing:

        -       The average price of Umpqua stock prior to closing is less than
                $6.75 per share;

        -       The average price of Umpqua shares drops ten percentage points
                more than the Nasdaq Bank Index; and

        -       Umpqua elects to increase the Exchange Ratio to avoid VRB's
                termination of the Merger Agreement.

        For more information, see "THE MERGER - Conversion of VRB Common Stock."

Q:      Why are the companies proposing to merge?

A:      Both companies share a belief in community banking that emphasizes
        responsiveness to local markets and the delivery of personalized
        services to customers. The company believe that the Merger will not
        change that commitment but believes that the Merger will strengthen the
        organization, permitting the combined bank to provide additional
        services and products to its depositors and larger loans to its
        borrowing customers. The Merger will also make available to customers of
        VRB the retail securities investment products from Strand, Atkinson,
        Williams & York, Umpqua's investment brokerage subsidiary.

        The combined company will have approximately twice the assets, market
        capitalization, number of shareholders and shares outstanding than
        either company alone and shareholders can be expected to benefit from
        the increased liquidity in trading of their shares. See "BACKGROUND AND
        REASONS FOR THE MERGER."

        THE BOARDS OF DIRECTORS OF BOTH COMPANIES UNANIMOUSLY RECOMMEND THAT
        THEIR RESPECTIVE SHAREHOLDERS APPROVE THE MERGER.

Q:      What is a "Merger of Equals?"

A:      The Merger is proposed as a "merger of equals" because it will result in
        a simple combination of the two companies; shareholders of both
        companies will continue as shareholders of the combined organization,
        the resulting Board of Directors will consist of directors from both
        organizations, the senior management of both organizations are expected
        to continue with the combined company, there is no overlap of market
        areas, no banking offices are expected to be closed, and the Exchange
        Ratio is based on a ratio that reflects the approximate relative book
        value of each organization.

Q:      Who will manage the combined company?

A:      The Board of Directors of Umpqua Holdings Corporation and Umpqua Bank
        following the Merger will consist of 11 directors, 6 of whom are
        designated by Umpqua and 5 of whom



                                       6
<PAGE>   13
        are designated by VRB. All shareholders of the combined company will
        vote on directors as their term of office expires. See "THE MERGER -
        Resulting Board of Directors of Umpqua and Umpqua Bank" for the identity
        and background of the continuing directors.

        Raymond P. Davis, President and CEO of Umpqua Holdings Corporation, will
        continue in that position with the holding company. William A. Haden,
        President and CEO of VRB and its subsidiary bank, will serve as the
        President and CEO of Umpqua Bank. The senior officers of both
        organizations are expected to continue with the combined company.

Q:      What do I need to do now?

A:      Just read this Joint Proxy Statement and mail your signed proxy card in
        the enclosed return envelope as soon as possible, so that your shares
        can be represented at the Umpqua or VRB special shareholders meeting.
        The Umpqua special meeting will take place on November ___, 2000 at
        _________. The VRB special meeting will take place on November _____,
        2000 at ________. See "UMPQUA SPECIAL MEETING" or "VRB SPECIAL MEETING,"
        as appropriate.

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

A:      Yes. You can change your vote at any time before your proxy is voted at
        the special meeting. You can do this in one of three ways. First, you
        can send a written notice stating that you would like to revoke your
        proxy. Second, you can 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 Umpqua or VRB, as the case may be.
        Third, you can attend the special meeting and vote in person. Simply
        attending the meeting, however, will not revoke your proxy. See "UMPQUA
        SPECIAL MEETING - Revoking a Proxy" or "VRB SPECIAL MEETING - Revoking a
        Proxy."

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

A:      Your broker may vote your shares only if you provide instructions on how
        to vote. Please tell your broker how you would like him or her to vote
        your shares. If you do not tell your broker how to vote, your broker
        will not vote your shares. This will have the same effect as a "no" vote
        on the Merger.

Q:      Should VRB stockholders send their stock certificates in now?

A:      No. After the Merger is completed, Umpqua will send VRB shareholders
        written instructions for exchanging their stock certificates. See "THE
        MERGER - Exchange of Stock Certificates."

Q:      What is the Fairness Hearing?

A:      In order to comply with federal securities laws regarding the issuance
        of Umpqua shares to VRB shareholders, a hearing will be held by the
        Director of the Oregon Department of Consumer and Business Services (the
        "Oregon Director") through a representative from the Oregon Division of
        Finance and Corporate Securities. The Oregon Director, after the
        hearing, will consider the fairness of the terms and conditions of the
        Merger and, if the Oregon Director finds that the Merger is fair, just
        and equitable and free from fraud, he will approve it subject to any
        conditions, limitations or restrictions as he finds necessary or
        appropriate.

Q:      Need I attend the Fairness Hearing?


                                       7
<PAGE>   14

A:      No. Although VRB shareholders are invited to attend the hearing if they
        choose, no input from them is required or expected. If a VRB shareholder
        would like to comment on the Merger, they may do so in writing as set
        forth in the notice sent to the VRB shareholders with this Proxy
        Statement.

Q:      When do you expect the Merger to be completed?

A:      Umpqua and VRB are working to complete the Merger as quickly as
        possible. In addition to Umpqua and VRB shareholder approval, certain
        regulatory approvals must be obtained, and there are other conditions to
        completing the Merger. Umpqua and VRB expect the Merger to be completed
        as early as December 1, 2000. See "THE MERGER - Conditions to the
        Merger."

Q:      Will I still receive regular cash dividends?

A:      VRB management expects that VRB shareholders will receive a regular
        semi-annual $0.12 per share dividend in October 2000. Umpqua
        shareholders are expected to receive a regular quarterly cash dividend
        of $0.04 per share in December 2000. If the Merger is effective prior to
        the record date for the Umpqua December dividend, VRB shareholders will
        also receive that cash dividend. Dividends in future years would be paid
        to all shareholders at the time and in the amounts determined by the
        company's new Board of Directors.

Q:      What are the tax consequences of the Merger?

A:      The Merger generally will be tax-free to you for federal income tax
        purposes. To review the tax consequences to shareholders in greater
        detail, see "THE MERGER - Certain Federal Income Tax Consequences."

        SPECIAL MEETINGS

        Umpqua Meeting

        The Umpqua meeting will be held at ______ p.m. on November __, 2000, at
________________, Roseburg, Oregon. If you are an Umpqua shareholder as of the
close of business on October ____, 2000, you may vote at the Umpqua meeting. At

                -       The Merger

                -       The adoption of the 2000 Stock Option Plan

        VRB Meeting

        The VRB meeting will be held at ______ p.m. on November ____, 2000, at
Rogue Valley Country Club, ________________, Medford, Oregon. If you are a VRB
shareholder as of the close of business on October 2, 2000, you may vote at the

Merger but not on the Stock Option Plan.

        Voting at the Meetings

        Whether you are an Umpqua or VRB shareholder, you do not need to attend
the meeting, although we invite you to do so. You may vote your shares by proxy
if you wish, and we encourage you to complete and return your proxy even if you
plan to attend the meeting. You should mark the enclosed revocable proxy to

                                       8
<PAGE>   15

meeting and your shares will be voted as you instruct. You may still attend the
meeting even if you submit a proxy.

        If you submit a proxy with no instructions, your shares will be voted in
favor of the Merger and, for Umpqua shareholders, in favor of the new stock
option plan. In addition, the named proxy holders will vote your shares in their
discretion on any other business properly brought before the meeting.

        You may revoke your proxy any time before the vote is taken at the
meeting by notifying the Corporate Secretary of your intention to do so.

OPINION OF INVESTMENT BANKERS

        Ragen MacKenzie, Inc. has delivered its written opinion to Umpqua and
D.A. Davidson & Co. has delivered its written opinion to VRB, to the effect that
the Merger, including the Exchange Ratio, is fair from a financial point of view
to the holders of each respective shareholder group.

NO DISSENTERS' RIGHTS

        Under Oregon law, holders of Umpqua and VRB stock do not have the right
to dissent from the Merger and obtain payment of the appraised value of their
shares.

APPROVAL OF NEW STOCK OPTION PLAN (UMPQUA SHAREHOLDERS ONLY)

        Umpqua shareholders will also be voting to approve the 2000 Stock Option
Plan that was approved by Umpqua's Board of Directors on September ___ 2000. The
current stock option plan was adopted in 1995 and authorized the issuance of a
total of up to 1,150,000 shares upon the exercise of options granted under the
plan (but no more than 10% of all outstanding shares). The number of available
shares is currently 431,000 prior to the application of the 10% limit. The
Merger Agreement provides for substitute options totaling 197,000 shares to be
issued to existing VRB option holders as of the effective date of the Merger,
leaving only 234,000 shares remaining for future grants. The Board of Directors
has adopted the new plan subject to approval by the Umpqua shareholders, which
would authorize grants of up to 1,000,000 shares but continue the limitation
that no grant can be made if existing options and later grants under the 2000
Stock Option Plan exceed 10% of outstanding shares. If the 2000 Stock Option
Plan is approved, the 1995 Plan would be terminated and no further grants would
be made under the 1995 Plan. No grants under the new plan have been made or
committed to any person at this time.

        THE UMPQUA BOARD OF DIRECTORS HAS RECOMMENDED THAT SHAREHOLDERS APPROVE
THE NEW PLAN.

EQUIVALENT PER SHARE DATA

        The table below presents:

        -       the closing price per share for Umpqua and VRB common stock as
                reported by the Nasdaq Stock Market on August 14, 2000, the last
                full trading day prior to the public announcement of the Merger,
                and as of _____________, 2000, the most recent date prior to the
                date of this Proxy Statement, together with the pro forma
                equivalent market value of VRB shares after giving effect to the
                Merger.

        -       the historical earnings, book value and cash dividends per share
                as of June 30, 2000 and the six months then ended, and as of
                December 31, 1999 and three years then ended, for Umpqua and
                VRB, together with the pro forma amounts for Umpqua and the pro
                forma equivalent amounts for VRB after giving effect to the
                Merger on a pooling-of-interests basis assuming the Merger had
                been effective during all the periods presented.

        The pro forma data assume an Exchange Ratio of 0.8135 shares of Umpqua
for each VRB share, but are not necessarily indicative of actual or future
operating results or the financial position that would have occurred or will
occur upon the consummation of the Merger. The pro forma equivalent per share
data is calculated by multiplying the pro forma per share data for Umpqua by
0.8135, the anticipated Exchange Ratio. Under certain circumstances, the
Exchange Ratio could be increased to 0.8500, but the increase would not
materially affect the pro forma per share data. This data should be read in
conjunction with the financial statements and other financial and pro forma
financial information included elsewhere in this Proxy Statement.

        Umpqua Dividend Reinvestment Plan. Umpqua maintains a dividend
reinvestment plan under which shareholders who elect to participate receive
shares of common stock in lieu of cash dividends. Cash dividends otherwise
payable to participating shareholders are used to purchase shares of Umpqua
common stock in the open market by a registered broker-dealer acting as agent
for plan participants.

        Expenses incurred in acquiring shares for the plan, including brokerage
commissions, are charged to the participating shareholders on a pro rata basis.
Participants may also be assessed an administrative charge for transactions,
including enrolling in or withdrawing from the plan, and withdrawal of shares
from the plan. As trading activity in the common stock has been limited, the
broker-dealer is permitted to acquire shares over a 30-day period. Participating
shareholders receive quarterly statements of their accounts, and do not receive
certificates for shares acquired under the plan unless requested. Umpqua serves
as the plan administrator.

                                  RISK FACTORS

        Completion of the Merger represents an investment by VRB shareholders in
Umpqua's common stock and an investment by Umpqua in VRB's assets and
liabilities, each of which will subject the respective investor to certain
risks. You should carefully consider the following risk factors as well as other
information contained in this Proxy Statement, before deciding how to vote on
the Merger.


                                       14
<PAGE>   21

THE INTEGRATION OF THE TWO BANKING OPERATIONS MAY NOT BE COMPLETED SMOOTHLY
RESULTING IN LOSS OF CUSTOMERS

        At the time of the Merger, the two subsidiary banks, Valley of the Rogue
Bank and South Umpqua Bank, will merge into one organization under the name of
"Umpqua Bank." VRB banking customers are accustomed to traditional community
bank branch facilities and services. South Umpqua Bank has transformed itself
from a traditional community bank into a community-oriented financial services
retailer. Among the steps taken by Umpqua to change its facilities, it has
remodeled many of its banking branches to resemble retail stores that include
distinct physical areas or boutiques such as a "serious about service center,"
"investment opportunity center" and "a computer cafe." Over a period of month
following the Merger, Umpqua intends to remodel and convert the larger Valley of
the Rogue Bank branches in a similar fashion. Such a conversion will involve
significant expenses, disrupt banking activities during the remodeling period
and would present a new look and feel to the banking services and products being
offered. There is a risk that some of the existing VRB customers will not stay
with Umpqua Bank during the remodeling period or after the conversion is
completed. Additionally, the cost of remodeling the branches and training VRB
personnel could exceed estimates and might not result in increased banking
activity, revenues or profits. Further, there may be delays in effecting the
conversion which could cause confusion and disruption in the business of those
branches.

INVOLVEMENT IN NON-BANK BUSINESSES MAY INVOLVE NEW RISKS

        Within the last year, Umpqua has acquired two licensed retail
broker-dealers, Strand, Atkinson, Williams & York, Inc. and Adams, Hess, Moore &
Co., both now operating under the Strand, Atkinson, Williams & York name as an
Umpqua subsidiary. The operation of commercial banking and retail investment
banking under common ownership has only recently been permitted by federal law
and the retail investment banking operations present special risks not
previously borne by community banks. For example, the investment banking and
brokerage industry is subject to fluctuations in the stock market that may have
a significant adverse impact on investment banking fees, customer activity and
investment portfolio gains or losses. Likewise, additional or modified
regulations may affect Umpqua's banking, investment banking and brokerage
operations. A decline in fees and commissions or losses suffered in the
investment portfolio could adversely affect the subsidiary's contribution to the
income of the holding company, and may increase the subsidiary's capital needs.
In its continuing expansion, Umpqua may acquire other financial services
companies whose successful integration is not assured and may present additional
management challenges and new risks to the company.

THE RESTRUCTURING AND INTEGRATION COSTS COULD EXCEED ESTIMATES; EXPECTED
CONSOLIDATION SAVINGS MAY NOT MATERIALIZE

        The companies estimate that they will incur approximately $2.0 million
in restructuring costs and related expenses at the time the Merger is
consummated. These costs include investment banking, accounting and legal fees
in connection with the Merger as well severance or change of control payments
under employment contracts and to employees whose positions may be eliminated.
Additional costs include system integration, store remodeling and disposal of
duplicative equipment. The actual costs could exceed these estimates.

        Further, Umpqua anticipates that as a result of the Merger, various cost
savings will accrue to the combined organization by eliminating duplicate
positions and outside services including



                                       15
<PAGE>   22

accounting, regulatory compliance, marketing and data processing. There is the
risk that Umpqua will not be able to realize the cost savings anticipated in the
amount or within the time anticipated.

your shares by proxy if you wish. You may mark the enclosed proxy card to
indicate your vote on the matters presented at the meeting, and the individuals
whose names appear on the proxy card will vote your shares as you instruct.

        If you submit a proxy with no instructions, the named proxy holders will
vote your shares in favor of the Merger and in favor of adoption of the 2000
Stock Option Plan. In addition, the named proxy holders will vote in their
discretion on such other matters that may be considered at the shareholders'
meeting. The Board of Directors has named __________________ and
___________________ as the proxy holders. Their names appear on the proxy form

mail) of your wish to revoke your proxy. You may also revoke your proxy by oral
request if you are present at the meeting.

proxy.

        PLEASE COMPLETE, DATE, AND SIGN THE ACCOMPANYING PROXY AND RETURN IT
PROMPTLY TO US IN THE ENCLOSED, POSTAGE-PAID ENVELOPE, EVEN IF YOU PLAN TO
ATTEND THE MEETING.

HOW WE DETERMINE A QUORUM

        We must have a quorum to conduct any business at the meeting.
Shareholders holding at least a majority of the outstanding shares of common
stock must either attend the meeting or submit proxies to have a quorum. If you
come to the meeting or submit a proxy but you abstain from voting on a given
matter, we will still count your shares as present for determining a quorum.

HOW WE COUNT VOTES

        The named proxies will vote your shares as you instruct on your proxy.
We will not count abstentions or broker non-votes for or against a matter
submitted to a vote of shareholders. Each share is entitled to one vote.

        A broker non-vote occurs when a broker or other nominee holder, such as
a bank, submits a proxy representing shares that another person actually owns,
and that person has not given voting instructions to the broker or other
nominee. A broker may only vote those shares if the beneficial owner gives the
broker voting instructions. We will count broker non-votes as present for
establishing a quorum.

        Approval of the Merger

        The affirmative vote of the holders of a majority of all shares of
Umpqua common stock outstanding on October 2, 2000 is required to approve the
Merger. An abstention or a broker non-vote will therefore have the effect of a
vote against the Merger.

        Approval of the 2000 Stock Option Plan

        The proposal to adopt the 2000 Stock Option Plan will be approved if
more shares are voted in favor of the proposal than voted against the proposal.
Therefore, we will not count abstentions and broker non-votes as votes for or
against the proposal.

HOW MANY SHARES DO DIRECTORS AND OFFICERS OWN

        As of October 2, 2000, directors and executive officers of Umpqua
beneficially owned ___________ shares, of which ________ are entitled to vote.
Those shares constitute ______% of the total shares outstanding and entitled to
be voted at the meeting. Pursuant to the Merger Agreement, each member of the
Umpqua Board of Directors has agreed to vote their shares in favor of the
Merger. We expect all directors and executive officers to vote in favor of both
proposals.

COSTS OF SOLICITATION

        Umpqua will bear the cost of soliciting of proxies from its
shareholders. In addition to using the mail, proxies may be solicited by
personal interview, telephone, and electronic communication. Banks, brokerage
houses, other institutions, nominees, and fiduciaries will be requested to
forward their proxy soliciting material to their principals and obtain
authorization for the execution of proxies. Officers and other employees or
agents of Umpqua and its bank subsidiary, South Umpqua Bank, acting on Umpqua's
behalf, may solicit proxies personally. Umpqua may pay compensation for
soliciting proxies, and will, upon request, pay the standard charges and
expenses of banks, brokerage houses, other institutions, nominees, and
fiduciaries for forwarding proxy materials to and obtaining proxies from their
principals. However, no such



                                       17
<PAGE>   24

payment will be made to any of Umpqua's subsidiaries acting through their
nominees or acting as a fiduciary.

WHEN AND WHERE THE MEETING WILL BE HELD

        The VRB special meeting of shareholders will be held on November ___,
2000, commencing at ____ p.m., local time at _________________________, Medford,
Oregon.

PURPOSE OF THE MEETING

        At the meeting, VRB shareholders will consider and vote on approval of
the Merger. Approval of the Merger will also constitute the election of
directors of the combined company to the terms described under "THE MERGER --
Board of Directors of the Combined Company."

WHO MAY VOTE

        If you were a VRB shareholder as of the close of business on October 2,
2000, you are entitled to vote at the meeting. As of that date, there were
___________ shares outstanding held by approximately ____ holders of record.

VOTING BY PROXY

        Shareholders do not have to attend the meeting, although we invite you
to do so. You may vote your shares by proxy if you wish, and we ask that you
provide a proxy even if you intend to attend the meeting. You may mark the
enclosed proxy card to indicate your vote on the matters presented at the
meeting, and the individuals whose names appear on the proxy card will vote your
shares as you instruct.

        If you submit a proxy with no instructions, the named proxy holders will
vote your shares in favor of the Merger. In addition, the named proxy holders
will vote in their discretion on such other matters that may be considered at
the shareholders' meeting. The Board of Directors has named James D. Coleman and
William A. Haden as the proxy holders. Their names appear on the proxy form
accompanying this proxy statement. You may name another person to act as your
proxy if you wish, but that person would need to attend the meeting in person or
further vote your shares by proxy.

REVOKING A PROXY

        You may revoke your proxy at any time before the vote is taken at the
meeting. You may revoke your proxy by submitting a proxy bearing a later date or
by notifying the Corporate Secretary of VRB (personally, in writing or by mail)
of your wish to revoke your proxy. You may also revoke your proxy by oral
request if you are present at the meeting.

        You are invited to attend the meeting even if you have submitted a
proxy. You should be aware that simply attending the meeting will not, of
itself, revoke a proxy.

        PLEASE COMPLETE, DATE, AND SIGN THE ACCOMPANYING PROXY AND RETURN IT
PROMPTLY TO US IN THE ENCLOSED, POSTAGE-PAID ENVELOPE, EVEN IF YOU PLAN TO
ATTEND THE MEETING.

HOW WE DETERMINE A QUORUM

        We must have a quorum to conduct any business at the meeting.
Shareholders holding at least a majority of the outstanding shares of common
stock must either attend the meeting or



                                       18
<PAGE>   25

submit proxies to have a quorum. If you come to the meeting or submit a proxy,
but you abstain from voting on a given matter, we will still count your shares
as present for determining a quorum.

HOW WE COUNT VOTES

        The named proxies will vote your shares as you instruct on your proxy.
We will not count abstentions or broker non-votes for or against a matter
submitted to a vote of shareholders but they will have the effect of a vote
against the proposal. Each share is entitled to one vote.

        A "broker non-vote" occurs when a broker or other nominee holder, such
as a bank, submits a proxy representing shares that another person actually
owns, and that person has not given voting instructions to the broker or other
nominee. A broker may only vote those shares if the beneficial owner gives the
broker voting instructions. We will count broker non-votes as present for
establishing a quorum.

        The affirmative vote of the holders of a majority of all shares of VRB
common stock outstanding on October 2, 2000 is required to approve the Merger.
An abstention or a broker non-vote will therefore have the effect of a vote
against the Merger.

HOW MANY SHARES DO DIRECTORS AND OFFICERS OWN

        As of October 2,2000, VRB directors and executive officers beneficially
owned ___________ shares, of which ________ are entitled to vote. Those shares
constitute ____% of the total shares outstanding and entitled to be voted at the
meeting. Pursuant to the Merger Agreement, each member of the VRB Board of
Directors has agreed to vote their shares in favor of the Merger Agreement. We
expect all directors and executive officers to vote in favor of the Merger.

COSTS OF SOLICITATION

        VRB will bear the cost of soliciting proxies from its shareholders. In
addition to using the mail, proxies may be solicited by personal interview,
telephone, and electronic communication. Banks, brokerage houses, other
institutions, nominees, and fiduciaries will be requested to forward proxy
soliciting materials to their principals and obtain authorization for the
execution of proxies. Officers and other employees or agents of VRB and its bank
subsidiary, Valley of the Rogue Bank, acting on VRB's behalf, may solicit
proxies personally. VRB may pay compensation for soliciting proxies, and will,
upon request, pay the standard charges and expenses of banks, brokerage houses,
other institutions, nominees, and fiduciaries for forwarding proxy materials to
and obtaining proxies from their principals. However, no such payment will be
made to any of VRB's subsidiaries acting through their nominees or acting as a
fiduciary.

HOW DID THE MERGER COME ABOUT?

        South Umpqua Bank was founded in Canyonville, Oregon in 1953. Its early
growth was accomplished by opening branches in Douglas County, but its growth
accelerated in 1994 when it focused its efforts on being a financial services
retailer, opening four new branches in Eugene and more recently a branch in each
of Salem and Portland, Oregon.

        Valley of the Rogue Bank opened in Rogue River in 1968 and has grown to
13 branches in Jackson and Josephine Counties. Much of this growth came from the
acquisition of Medford State



                                       19
<PAGE>   26

Bank in 1987 and Colonial Banking Company in 1998 and the purchase from the FDIC
of two branches of banks that failed in the 1980s.

        Each company has long preferred to remain independent and continue their
community banking services in their local communities. Each has pursued a growth
strategy founded on progressive expansion of its geographic market through
branch acquisitions or new branches in areas contiguous to its existing market
area or in areas where expansion opportunities were consistent with the overall
operating and strategic plan. Nonetheless, each believed that under appropriate
circumstances, an alliance or merger with similar community bank organizations
could provide benefits for both shareholders and customers.

        Over the past few years, Umpqua and VRB senior management have had
informal conversations regarding a potential merger, but the discussions never
progressed beyond brief inquiries. However, prompted in part by the possibility
that pooling-of-interest accounting treatment might be terminated at the end of
2000 and in response to previous informal invitations for additional dialogue,
the president of VRB met with the president of Umpqua in April and discussed the
parameters of a possible merger of equals. At this meeting, initial discussions
covered the name of the continuing institution, board representation, possible
exchange ratios and senior management positions. Over the ensuing weeks, many
conversations occurred between senior management and between senior management
and their respective Boards of Directors regarding the progress of these
preliminary conversations. Umpqua retained Ragen MacKenzie on May 24, 2000 to
provide financial advisory services. In June, draft agreements were circulated
which helped focus on open issues. The parties exchanged confidential
information based upon a Nondisclosure and Confidentiality Agreement signed June
14, 2000. In June, the Boards of Directors of both companies met and authorized
their management to continue to proceed with the negotiations of a definitive
agreement. By mid July, the essential terms of the Merger had been negotiated.
On July 19, 2000, the Umpqua Board of Directors met with legal counsel and its
financial advisors, Ragen MacKenzie Inc., to review the terms of the Agreement
and give final approval to the transaction. As it appeared that an agreement was
possible, VRB retained D.A. Davidson, an investment banking firm, to provide an
opinion on whether the transaction was fair to the VRB shareholders from a
financial point of view. On July 20, 2000, VRB Board of Directors met with its
legal counsel, Davis Wright Tremaine LLP, Moss Adams LLP, its independent
auditors, and D.A. Davidson & Co., to discuss the terms of the proposed
Agreement, the status of due diligence, and the recommendations of its financial
advisors and outside accounting firm. At a subsequent meeting on August 14,
2000, the VRB Board of Directors received the final due diligence report and a
presentation by D.A. Davidson & Co., and authorized the execution of the Merger
Agreement.

REASONS FOR THE MERGER - GENERAL

        Both Umpqua and VRB share a common banking philosophy and strategy,
which emphasizes responsiveness to local markets and the delivery of
personalized services. The companies intend that the Merger will not alter their
community bank focus but will enhance the services to customers. The parties'
geographic markets and products are complementary. South Umpqua's primary market
is Douglas and Lane County with an emerging presence in the Portland and Salem
market areas. VRB's primary market area is immediately south of Douglas County
in Jackson and Josephine Counties. Following the Merger, the combined bank will
have operations in all of the major population centers along the Oregon I-5
corridor. The expansion into the Portland and Salem markets is expected to
provide the combined bank with additional loan



                                       20
<PAGE>   27

opportunities which should further diversify its loan portfolio. Further, the
increased capital of the combined bank will permit larger loans to existing and
new customers.

        The Merger is expected to provide increased efficiencies and other cost
savings, particularly in data processing and other administrative operations.
The larger size of the combined company also will enable it to acquire and
utilize technology and human resources more efficiently then could either of the
existing banks individually. The Merger is also expected to increase the
management depth of the combined company and its banking subsidiary, enhancing
its competitive ability.

        The Merger can be expected to result in a broader public market for the
common stock, which may increase the combined company's shareholder base and
market capitalization, in turn providing a greater market interest in, and
liquidity for, shareholder investments.

        Umpqua's and VRB's Board of Directors each believe for the above reasons
as well as the reasons set forth below, that the Merger would be in the best
interest of its company's shareholders.

REASON FOR MERGER - UMPQUA

        At its meeting on July 19, 2000, the Board of Directors determined that
the Merger was fair to and in the best interest of Umpqua and its shareholders
based in part on the initial opinion of its financial advisor.

        The Umpqua Board of Directors determined the Merger would accelerate its
business strategy of providing banking services throughout the Oregon population
centers along the I-5 corridor. After the Merger, the combined company would be
the third largest community bank in Oregon, thereby potentially providing
customers and shareholders with certain advantages of both a community banking
organization and a larger, regional bank organization.

        The Umpqua Board of Directors determined that the Merger would best
advance its strategic plan because the combination of two financially strong
institutions with complementary business strategies would create a stronger
institution with greater size, flexibility, breadth of services, efficiency and
profitability than Umpqua would possess on a stand-alone basis. The Umpqua Board
of Directors believe that each institution is well managed and possesses
management philosophies and a strategic focus that are compatible to those of
the other.

        In reaching this determination, the Umpqua Board of Directors consulted
with Umpqua's management as well as its financial, accounting and legal advisors
and considered a number of factors including:

               (a) The effectiveness of the Merger in implementing and
accelerating Umpqua's growth strategy;

               (b) A presentation by management of (i) its due diligence review
of VRB, including the business, operations, earnings, asset quality, financial
conditions, and corporate culture of VRB on a historical, prospective, and pro
forma basis, (ii) product compatibility, the compatibility of corporate goals
and the respective contributions the parties would bring to a combined
institution, (iii) the enhanced opportunities for acquisition and growth that
the Merger makes possible as a result of greater capitalization of the combined
companies and the anticipated enhanced liquidity of its stock, and (iv) the
expanded opportunities for revenue enhancement and synergies that are expected
to result from the Merger;




                                       21
<PAGE>   28

               (c) The terms of the Merger, the Umpqua and VRB Stock Option
Agreements and other documents executed in connection with the Merger, which are
generally reciprocal in nature;

               (d) The opinion of Ragen MacKenzie, Inc., discussed elsewhere in
this Proxy Statement, that as of July 19, 2000 (and as of October ___, 2000),
that the Exchange Ratio was fair, from a financial point of view, to the holders
of Umpqua Stock;

               (e) The opportunity to strengthen and deepen the management team
by integrating the existing management teams of both Umpqua and VRB; and

               (f)    The financial, tax and accounting effects of the Merger.

        The Umpqua Board of Directors did not assign any specific or relative
weight to the foregoing factors in the course of its consideration.

REASONS FOR THE MERGER - VRB

        At its meeting held on August 14, 2000, VRB's Board of Directors
authorized the execution of the Merger Agreement and recommended approval of the
Merger by the shareholders of VRB. The Board of Directors believes that the
Merger enhances shareholder value by expanding the Company's business
geographically while retaining the service strategies that are unique to
community banking. VRB's Board of Directors believes that Umpqua is an
innovative financial services company that has goals and philosophies similar to
those of VRB, that Umpqua has demonstrated a history of strong growth and
quality customer services, and that it operates in geographic markets in which
VRB desires to conduct business. Because these factors fit closely with VRB's
business objectives, and because the Merger affords VRB's management, directors
and shareholders a significant voice in the resulting enterprise, the Board did
not extensively consider a sale of VRB or any other transaction as an
alternative to the Merger, although it did examine a variety of strategic
options before deciding to pursue a transaction with Umpqua. VRB's Board
believes that a merger of equals transaction presents a unique strategic
opportunity that should be considered on its own merits. The board also
considered that the Merger would not necessarily preclude consideration of other
transactions in the future for the combined companies if the opportunity should
arise.

        In addition, the VRB Board of Directors considered a variety of factors
including:

               (a) The terms of the Merger, including the Exchange Ratio, the
Umpqua and VRB Stock Option Agreements and the other documents executed in
connection with the Merger, which are generally reciprocal in nature;

               (b) A presentation by management of (i) its due diligence review
of Umpqua, and that of its attorneys, accountants and financial advisor
including the business, operations, earnings, asset quality, financial
conditions, and corporate culture of Umpqua on a historical, prospective, and
pro forma basis, (ii) product compatibility, the compatibility of corporate
goals and the respective contributions the parties would bring to a combined
institution, (iii) the enhanced acquisition and growth opportunities that the
Merger makes possible as a result of greater capitalization of the combined
companies and the anticipated enhanced liquidity of its stock, and (iv) the
expanded opportunities for revenue enhancement and synergies that are expected
to result from the Merger;

               (c) The opinion of D.A. Davidson & Co., discussed elsewhere in
this Proxy Statement, that as of August 14, 2000 (and as of October _____,
2000), the Exchange Ratio was fair, from a financial point of view, to the VRB
shareholders;




                                       22
<PAGE>   29

               (d) VRB's long-term strategy of (i) seeking to expand its
operations along the I-5 corridor, and in particular its goal of extending its
banking operations into the Willamette Valley market area; and (ii) enhancing
the range of financial services available to its customers, such as the retail
brokerage services provided by Umpqua's subsidiary, Strand, Atkinson, Williams &
York, Inc.;

               (e) The market value of Umpqua Stock that VRB shareholders will
receive based upon the Exchange Ratio, including possible adjustments to that
ratio that have the effect of protecting VRB's shareholders from certain price
declines prior to closing;

               (f) The greater number of shareholders and the increased market
capitalization of the combined company which may result in increased interest in
Umpqua's stock from institutional investors and market professionals, resulting
in improved liquidity for shareholders;

               (g) The representation VRB Directors will have on the Board of
Directors of both Umpqua and Umpqua Bank and the positions VRB's senior
management will assume in the combined organization; and

               (h) The benefits to VRB's existing customers afforded by
increased capital of the combined bank.

        The VRB Board of Directors did not assign any specific or relative
weight to the foregoing factors in the course of its consideration.

RECOMMENDATIONS OF BOARDS OF DIRECTORS

        The Boards of Directors of VRB and Umpqua unanimously recommend that
their respective shareholders vote for the approval of the Merger.

OPINION OF UMPQUA'S FINANCIAL ADVISOR

        Ragen MacKenzie was retained on May 24, 2000 by Umpqua to provide
financial advisory services regarding the proposed transaction with VRB.

        Ragen MacKenzie delivered its oral opinion on July 19, 2000, to the
Umpqua Board, confirmed by a written opinion dated as of July 19, 2000, that, as
of that date, the Exchange Ratio was fair from a financial point of view to the
Umpqua shareholders. Ragen MacKenzie reconfirmed its opinion in writing as of
October __, 2000 (the "Umpqua Opinion").

        The full text of the Umpqua Opinion, which sets forth the assumptions
made, procedures followed, matters considered and limitations on the review
undertaken, is attached as Appendix II to this Proxy Statement with the firm's
consent and is incorporated herein by reference. The Umpqua Opinion is directed
only to the fairness to the Umpqua shareholders of the Exchange Ratio from a
financial point of view and does not constitute a recommendation to any Umpqua
stockholder as to how to vote on the Merger. This description of the Umpqua
Opinion is qualified in its entirety by reference to Appendix II. Umpqua
shareholders are urged to read the Umpqua Opinion in its entirety.

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, including derivative securities, of Umpqua or
VRB for its own account and for the accounts of customers.

                Scope of Review

        -       In connection with the Umpqua Opinion, Ragen MacKenzie reviewed,
                among other things, the Agreement;

        -       a preliminary draft of this Proxy Statement;

        -       Annual Reports to Shareholders and Annual Reports on Form 10-K
                of Umpqua and VRB for the 3 years ended December 31, 1999;

        -       the offering circular dated April 1, 1998, as amended, relating
                to the public offering of Umpqua common stock;

        -       the registration statement on Form S-1 dated October 3, 1997, as
                amended, relating to the public offering of VRB's common stock;

        -       interim reports to shareholders and Quarterly Reports on Form
                10-Q of Umpqua and VRB;

        -       other communications from Umpqua and VRB to their respective
                shareholders; and

        -       internal financial analyses and forecasts of Umpqua and VRB
                prepared by their respective managements, including forecasts of
                cost savings and revenue opportunities (the "Synergies")
                expected to be achieved as a result of the Merger.

        Ragen MacKenzie also held discussions with members of the senior
management of Umpqua and VRB regarding the strategic rationale for, and the
potential benefits of the Merger. In addition, Ragen MacKenzie reviewed the
reported price and trading activity for the Umpqua common stock and the VRB
common stock, compared financial and stock market information for Umpqua and VRB
with similar information for other companies the securities of which are
publicly traded, reviewed the financial terms of certain recent business
combinations in the commercial banking industry specifically and performed such
other studies and analyses as it considered appropriate.

        Assumptions

        Ragen MacKenzie assumed and relied upon the accuracy and completeness of
all the financial and other information that it reviewed in rendering the Umpqua
Opinion. In that regard, Ragen MacKenzie assumed, with the Umpqua Board's
consent, that the financial forecasts (including, without limitation, the
Synergies and projected restructuring charges) had been reasonably prepared on a
basis reflecting the best currently available judgments and estimates of Umpqua
and VRB, and that such forecasts will be realized in the amounts and at the
times contemplated thereby. Ragen MacKenzie 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 the Umpqua Board's consent, that
such allowances for each of Umpqua and VRB are in the aggregate adequate to
cover all such losses. In addition, Ragen MacKenzie did not review individual
credit files nor did it make an independent evaluation or appraisal of the
assets and liabilities of Umpqua or VRB or any of their subsidiaries, and it had
not been furnished with any such evaluation or appraisal. Ragen MacKenzie also
assumed, with the Umpqua Board's consent, that the Merger will be accounted for
as a pooling-of-interests and that obtaining any necessary



                                       24
<PAGE>   31

regulatory approvals and third party consents for the Merger or otherwise will
not have a material adverse effect on Umpqua or VRB or the combined company. In
addition, the Umpqua Opinion does not address the relative merits of the Merger
as compared to any alternative business transaction that might be available to
Umpqua.

        The following is a brief summary of the material, financial analyses
presented to the Umpqua Board on July 19, 2000 by Ragen MacKenzie.

        Exchange Ratio History. Ragen MacKenzie calculated the ratio of the
average market price per share of VRB common stock to the average market price
per share of Umpqua common stock over selected periods ending on July 14, 2000
(the "Base Date") and dating back two years.

        Public Market Comparison. Ragen MacKenzie presented a public market
comparison of VRB and Umpqua and a selected group of other publicly traded
community banking organizations in Oregon (the "Oregon Companies") consisting
of:

        -       Cascade Bancorp - Centennial Bancorp

        -       Columbia Bancorp

        -       Independent Financial Network

        -       Umpqua Holdings Corporation

        -       VRB Bancorp

        -       West Coast Bancorp

        Ragen MacKenzie also analyzed a secondary group of publicly traded
community banking organizations in the state of Washington (the "Washington
Companies") consisting of:

        -       Columbia Banking Systems

        -       Frontier Financial Corp.

        -       Washington Banking Corp.

        -       City Bank

        -       United Security Bancorp

        This comparison was presented on the basis of various financial ratios
and other indicators, including among other things, market price to earnings per
share ("EPS") ratios, historical price to stated book value and tangible book
value ratios, and projected 2001 EPS. The Oregon Companies and Washington
Companies were selected for comparison purposes through a review of publicly
traded banking institutions with similar operating characteristics. In general,
financial data presented was as of the quarter ended June 30, 2000 and market
data was as of July 14, 2000. Efficiency ratios and net interest margins were
presented as of December 31, 1999.

        Ragen MacKenzie compared estimated ratios of price to EPS for VRB (based
on management projections



                                       25

provided by VRB and Umpqua (based on management projections provided by Umpqua
with the harmonic mean of the ratios for the Oregon Companies and Washington
Companies for 2000 and 2001. The harmonic mean is calculated by taking the
reciprocal of the arithmetic mean of the reciprocals of a finite set of numbers.
Ragen MacKenzie believes this mean calculation handles outlier data points in a
less subjective manner than excluding them. Additionally, Ragen MacKenzie
presented a public market comparison of VRB, Umpqua and the Oregon Companies, on
the basis of, among other things, return on average common equity ("ROACE"),
return of average assets ("ROAA"), net interest margin, efficiency ratios, and
deposit premiums similar multiple comparisons were made with the Washington
Companies. The following table shows the comparisons.

        Discounted Dividend Stream and Terminal Value Analysis--Umpqua. Ragen
MacKenzie performed a discounted dividend stream analysis for Umpqua based upon
management's projected dividend payout for the years 2000, 2001, 2002, and using
the three-year average payout ratio of 22% to estimate the dividend payout in
2003, and using Terminal Values ranging from 12x to 16x and discount rate of
10-14%. Based on this methodology, Ragen MacKenzie calculated implied share
values for Umpqua common stock ranging from $8.51 to $12.44.

        Discounted Dividend Stream and Terminal Value Analysis--VRB. Ragen
MacKenzie performed a discounted dividend stream analysis for VRB based on a
three-year average payout ratio of 35% and using Terminal Values ranging from
12x to 16x and discount rate of 10-14%. Based on this methodology, Ragen
MacKenzie calculated implied share values for VRB common stock ranging from
$6.44 to $9.32.

        Contribution Analysis. Ragen MacKenzie analyzed certain historical and
estimated financial information for VRB and Umpqua and the pro forma combined
entity resulting from the Merger. The following table shows the percentage
contributions of each company to the indicated values to the combined company.

        Pro Forma Combined Financial Analysis. Ragen MacKenzie presented pro
forma combined EPS to analyze the pro forma combined impact of the Merger. This
analysis is based on management's projections of financial results as well as
the synergies relating to the Merger.

        For Umpqua, the 2000 standalone and pro forma combined EPS were each
$0.72 and $0.73, respectively, representing 1.2% accretion; the 2001 standalone
and pro forma combined EPS were $0.81 and $0.87, respectively, representing 6.7%
accretion.

        Comparable Transaction Analysis - Ragen MacKenzie also analyzed selected
recent transactions ("Comparable Transactions") deemed relevant to the proposed
transaction in which certain public companies acquired other companies. For this
analysis, Ragen MacKenzie reviewed seven transactions of banks located in the
Western US including:

        -       Whitney Holdings/Bank of Houston

        -       Greater Bay Bancorp/Mount Diablo Bancshares

        -       Gold Banc Corp/Countybanc Holding Corp

        -       Wells Fargo/North County Bancorp

        -       Compass Bancshares/Western Bancshares

        -       US Bancorp/Penisula Bank

        -       SJNB Financial/Saratoga Bancorp

        Ragen MacKenzie's analysis of the consideration paid in the Comparable
Transactions generated harmonic mean multiples of transaction value to equity,
tangible equity, and net income of 2.72x, 2.90x, and 15.42x, respectively,
compared to 1.60x, 2.10x and 11.33x, respectively, for the Merger. Ragen
MacKenzie also analyzed the deposit premiums of the Comparable Transactions
which had a harmonic mean of 15.8%, compared to 7.6% for the Merger.

        The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. Ragen
MacKenzie believes that its analyses must be considered as a whole and that
selecting portions of its analyses, without considering the analyses taken as a
whole, would create an incomplete view of the process underlying the analyses
set forth in the Umpqua Opinion. In addition, Ragen MacKenzie considered the
results of all such analyses and did not assign relative weights to any of the
analyses, so the ranges of valuations resulting from any particular analysis
described above should not be taken to be Ragen MacKenzie view of the actual
value of Umpqua or a combination of Umpqua and VRB.

        In performing its analyses, Ragen MacKenzie made numerous assumptions
with respect to industry performance, general business, economic and regulatory
conditions and other matters, many of which are beyond the control of Umpqua or
VRB. The analyses performed by Ragen MacKenzie are not necessarily indicative of
actual values, trading values or actual future results which might be achieved,
all of which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as part of Ragen MacKenzie's
analysis of the fairness of the Exchange Ratio to Umpqua Stockholders from a
financial point of view. The analyses do not purport to be appraisals or to
reflect the prices at which a company might be sold. In addition, as described
above, the Umpqua Opinion was one of many factors taken into consideration by
the Umpqua Board in making its determination to approve the Merger.
Consequently, the analyses described above should not be viewed as determinative
of the Umpqua Board's or Umpqua management's opinion with respect to the value
of Umpqua or a combination



                                       27
<PAGE>   34

of Umpqua and VRB, or of whether the Umpqua Board or Umpqua management would
have been willing to agree to a different exchange ratio. Umpqua placed no
limits on the scope of the analysis performed, or opinion expressed, by Ragen
MacKenzie.

        Umpqua has agreed to pay Ragen MacKenzie a fee of $100,000 in cash for
the delivery of the opinion dated July 19, 2000, and an additional fee of
$375,000 in cash upon consummation of the Merger. In addition, Umpqua has agreed
to indemnify and hold harmless Ragen MacKenzie and certain related parties, to
the full extent lawful, from and against certain liabilities and expenses,
including certain liabilities under the federal securities laws, incurred in
connection with its engagement.

OPINION OF VRB'S FINANCIAL ADVISOR

        D.A. Davidson & Co. was retained to provide VRB's board with an opinion
of the fairness from a financial viewpoint of the Exchange Ratio. The written
opinion dated August 14, 2000, reconfirmed October __, 2000, is attached as
Appendix III with the consent of D.A. Davidson & Co. Davidson, as part of its
investment banking business, is engaged in the valuation of banking and other
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. VRB's Board of Directors retained Davidson based
upon its experience as a financial advisor in mergers and acquisitions of
financial institutions and its knowledge of financial institutions. VRB did not
retain Davidson to negotiate the proposed transaction and the terms and
conditions of the transaction were negotiated directly by and between VRB and
Umpqua and their respective other representatives.

Review Procedures.  In connection with providing its opinion, Davidson

        -       reviewed the Merger Agreement;

        -       reviewed certain publicly available financial statements and
                regulatory information concerning VRB and Umpqua;

        -       reviewed certain internal financial statements and other
                financial and operating data of VRB and Umpqua provided to it by
                managements of VRB and Umpqua;

        -       discussed the past and current operations, financial condition,
                and future prospects of VRB and Umpqua with their executive
                managements, including the chief executive officer of Strand,
                Atkinson, Williams & York;

        -       compared the relative contributions of assets, liabilities,
                income and expenses to the combined corporation by VRB and
                Umpqua in the Merger to those of certain other banks and thrifts
                in the United States which recently engaged in a merger of
                equals transaction;

        -       analyzed the pro forma results that the combined company could
                produce through the end of 2002 based upon forecasts prepared by
                managements of VRB and Umpqua; and

        -       performed other analyses and reviews as it deemed appropriate.

        In connection with its review, Davidson relied upon and assumed the
accuracy and completeness of all of the information listed above provided to it
or made publicly available. Davidson did not assume any responsibility for
independent verification of the information. We assumed that the internal
confidential financial projections prepared independently by the parties'
respective management were reasonably prepared, reflecting the best currently
available estimates and judgments of the future financial performance of the
combined operation, and did not independently verify the validity of their
assumptions.




                                       28
<PAGE>   35

        Davidson did not make any independent evaluation or appraisal of the
assets and liabilities of VRB or Umpqua, nor was it furnished with any
appraisals. With VRB's consent, Davidson did not examine individual loan files
of VRB or Umpqua. Davidson's personnel are not experts in the evaluation of loan
portfolios for the purpose of assessing the adequacy of the allowance for loan
losses and assumed that these allowances are, in the aggregate, adequate to
cover the losses.

        The Davidson opinion was predicated on the Merger receiving tax-free
reorganization treatment and qualifying as a pooling of interests for accounting
purposes. Davidson provided its opinion without regard to the necessity for, or
level of, any restrictions, obligations, undertakings or other actions, which
may be imposed or required in the course of obtaining regulatory approval for
the Merger.

        The opinion was necessarily based upon economic, market and other
conditions in effect on and the information made available to Davidson as of
August 14, 2000. No limitations were imposed on Davidson regarding the scope of
its investigation or otherwise by VRB or Umpqua.

        Based on the results of the various analysis described below, Davidson
concluded that the Exchange Ratio specified in the Merger Agreement is fair,
from a financial point of view, to VRB shareholders.

        The following is a summary of the analyses performed by Davidson in
connection with its opinion. The following discussion contains financial
information concerning VRB and Umpqua as of June 30, 2000.

        Valuation Methods. In connection with providing its opinion, Davidson
performed a variety of financial analyses, including those summarized in the
following sections. The information provided is not a complete description of
the analyses that were used in reaching its opinion. The preparation of its
fairness opinion involves various determinations and judgments as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances.

        A fairness opinion is not readily susceptible to a partial analysis or
summary description. While we provided the Board with the results of the various
analyses that follow, Davidson believes that all of our analysis must be
considered in its entirety and that selecting portions of its analysis and
factors considered by it, without considering all analyses and factors, or
attempting to assign relative weights to some or all such analyses and factors,
or including other discrete analyses or factors, could create an incomplete view
of the evaluation process underlying our opinion.

        In performing our analyses, Davidson made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of VRB, Umpqua, the combined
company and Davidson.

        The following lists the summary analyses presented by Davidson to VRB's
Board of Directors on August 14, 2000:

        -       Comparable Company Analysis and Historical Stock Data Analysis

        -       Exchange Ratio Analysis and Analysis of Relative Contributions
                of Parties

        -       Comparable Transaction Analysis

        -       Pro Forma Merger Analysis



                                       29

        Comparable Company Analysis. Davidson compared the financial performance
and market performance of VRB and Umpqua based on various financial measures of
earnings performance, operating efficiency, capital adequacy and asset quality
and various measures of market performance, including but not limited to,
price-to-book values, price-to-earnings and dividend yields to those selected
bank holding companies.

        For the purpose of such analysis, the financial information used by
Davidson was as of and for the quarter ending June 30, 2000. Market price
information was as of August 11, 2000. Davidson selected publicly traded banking
companies in the western United States on which its routinely publishes an
equity research monitor list for institutional investors.

        Davidson's analysis showed the following concerning VRB's financial
performance:

        Davidson's analysis further showed the following concerning VRB's market
performance:

        -       VRB's price to earnings per share multiple based on 2000
                projected earnings was 8.61 times, compared to an average of
                13.50 and median of 11.30;

        -       the price to earnings per share multiple based on 2001 projected
                earnings was 7.95 times, compared to an average of 10.10 and
                median of 9.60;

        -       the price to book value per share was 1.21 times, compared to an
                average of 1.52 and median of 1.47; and

        -       the dividend yield was 4.57% compared to an average of 2.25% and
                median of 2.36%.

        Davidson's analysis showed the following concerning Umpqua's financial
performance:

</TABLE>


        Davidson's analysis further showed the following concerning Umpqua's
market performance:

        -       that Umpqua's price to earnings per share multiple based on 2000
                projected earnings was 11.46 times, compared to an average of
                13.50 and median of 11.30;


                                       30
<PAGE>   37

        -       the price to earnings per share multiple based on 2001 projected
                earnings was 10.06 times, compared to an average of 10.10 and
                median of 9.60;

        -       the price to book value per share was 1.62 times, compared to an
                average of 1.52 and median of 1.47; and

        -       the dividend yield was 1.94% compared to an average of 2.25% and
                median of 2.36%.

        Historical Stock Data Analysis. Davidson reviewed weekly stock price
data for VRB common stock and Umpqua common stock compared to the Nasdaq Bank
Index and S&P Banking Index for the period from January 1999 through August 11,
2000. This analysis showed that on a relative performance basis, VRB's and
Umpqua's stock prices went down 32% and 15%, respectively, compared with a
reduction of 10% for the Nasdaq Bank Index and 10% for the S&P Banking Index.

        Merger Of Equals. For a merger to be considered a merger of equals
rather than an acquisition of one party by the other, the two parties must be of
relatively equal size, based on assets, revenues, net income, profitability, or
some other relevant financial measure. Another primary condition that
differentiates a merger of equals from an acquisition is the fact that neither
merger partners' shareholders receive a significant premium for their shares.
Whether a premium has been paid in a merger between two companies with publicly
traded stocks that have well established, reliable market prices can be easily
assessed based on the stock exchange ratio and relative market prices.

        On the other hand, for closely-held companies or those lacking well
established markets for their stock, this assessment is commonly based on the
relative impact on the per share measures of book value and earnings for the
merger partners, expressed in terms of accretion/dilution. In this context,
accretion refers to an increase in the book value or earnings represented by the
shares of the new, combined entity over the book value or earnings represented
by the shares of the parties to be merged. Dilution is the term used if the book
value or earnings on an equivalent share basis is less in the combined entity
than in the separate parties to the Merger.

        Exchange Ratio Analysis. In a merger of equals between two thinly traded
companies, such as Umpqua and VRB, it is not necessary to explicitly establish
an absolute dollar value for either of the two companies. The relevant value to
be determined is the relative value of one partner to the other. These values
are represented by the exchange ratio. Comparisons between mergers of equals can
be made based on the contribution the two partners make to the new aggregate
entity and the impact to the book value and earnings per share for each group of
shareholders, expressed in terms accretion or dilution.

        A large range between the accretion to one merger partner and the
dilution to the other generally shows that there are factors to be considered
that are not reflected in the equity balances or in net income, such as an
expected material decline in future earnings or balance sheet growth. After a
due diligence review of VRB and Umpqua and consultation with their managements,
Davidson did not discover any such factors that would materially impact the
Exchange Ratio.

        Analysis Of Relative Contributions Of Parties. The following chart
depicts the relative financial contributions of VRB and Umpqua to the merged
entity based on various items reported in their respective balance sheets and
income statements.

RELATIVE CONTRIBUTIONS AS OF JUNE 30, 2000

<TABLE>

Assets                                   44.30%               55.70%
Loans                                    45.60%               54.40%
Deposits                                 44.70%               55.30%
Equity                                   47.30%               52.70%
Net Interest Income                      47.30%               52.70%
Non-Interest Income                      20.50%               79.50%
Non-Interest Expense                     39.00%               61.00%
Net Income                               47.70%               52.30%
</TABLE>


        Each of these measures shows that the relative contributions of VRB and
Umpqua to the combined company are very close. The relative contributions track
well to the proposed 0.8135 Exchange Ratio.

        Applying the exchange ratio to VRB's common stock results in VRB
shareholders owning approximately 47% of the combined company. The data in the
chart above shows that this percentage is very close to the percentage
contribution of VRB assets, equity and earnings to the combined company among
other variables.

        For VRB shareholders, the Merger will result in a decrease in book value
per share of 1.4% and a decrease in earnings per share of 3.3%. For Umpqua
shareholders, the merger will result in an increase in book value per share of
0.7% and will be neutral to earning per share. The accretion/dilution analysis
shows that the impact of the Exchange Ratio on both VRB and Umpqua shareholders
is similar and that the difference is very narrow as compared to similar
transactions.

        The calculation of the Exchange Ratio based only upon stated book at
June 30, 2000 without certain typical adjustments slightly favors VRB
shareholders as adjustments to the Exchange Ratio based upon stated vs. tangible
book value per share, mark-to-market of held for sale in the company's
investment portfolio and options outstanding and/or vested would lower the
Exchange Ratio.

        Comparison to Selected Transactions. After completing its analysis of
the Exchange Ratio based on the relative contributions of the parties, Davidson
reviewed comparable transactions to validate its analysis. Davidson performed an
analysis of selected pending or recently completed mergers of equals of banking
organizations in the United States with comparable characteristics to the
Merger. Generally, the comparable transactions reinforced Davidson's opinion
that the Exchange Ratio was fair.

        Davidson's initial selection of a guideline group yielded 22
transactions covering a period from January 1, 1999 to June 30, 2000. In
reviewing this selection, Davidson determined that a number of transactions were
acquisitions, not mergers of equals. Another group of transactions was clearly
not comparable to the subject transaction, generally due to size. And, finally,
in many cases the financial data were inadequate for purposes of comparison.
Therefore, five transactions from the original group are presented as being
representative to test its conclusion.

        These comparable transactions consisted of five mergers of banks with
assets of between $100 million and $600 million that were announced between
January 1, 1999 and June 30, 2000 for which complete data were available:

</TABLE>


        As illustrated by the chart above, the comparable transactions showed
much wider ranges of accretion to dilution than the proposed merger between
Umpqua and VRB. If the results for the Merger had fallen outside range for the
comparative transactions, Davidson would have questioned the fairness of the
Exchange Ratio to VRB shareholders. From a comparative perspective, the effect
of the proposed Exchange Ratio in this merger best mimics the relative
contributions of the two companies when examined against other comparable
transactions.

        Conclusions. Based on the foregoing analysis, Davidson concluded that
the narrow range of accretion to dilution in the Merger between supports an
opinion that the exchange ratio is fair, from a financial point of view, to VRB
shareholders. Davidson's conclusion is based on the following results of its
comparison of the selected transactions to the results for the merger between
Umpqua and VRB:

        -       The absolute difference between the accretion and dilution to
                book value within a transaction ranged from 0.5% to 9.5%
                compared with the absolute difference of the accretion and
                dilution implied in the proposed Merger of 2.1% based on the
                June 30, 2000 book values for VRB and Umpqua without adjusting
                book value for any options.

        -       The absolute difference between the accretion and dilution to
                earnings within a transaction ranged from 2.9% to 22.4% compared
                with the absolute difference of the accretion and dilution
                implied in the proposed Merger of 3.3% based on the six months
                earnings to June 30, 2000 for Umpqua and VRB and applying the
                treasury stock method for calculating fully diluted weighted
                average shares outstanding for the period.

        -       Dilution to book value ranged from 0.2% to 4.4% compared to
                dilution to VRB book value implied in this Merger of 1.4%.
                Dilution to earnings ranged from 1.0% to 10.2% compared to
                dilution to VRB earnings implied in the proposed Merger of 3.3%.
                The analysis assumes no adjustment to book value for options but
                does include options in calculation of fully diluted shares.

        -       Accretion to earnings ranged from 1.9% to 12.2% compared to the
                neutral effect on Umpqua's earnings implied in this Merger.
                Accretion to book value ranged from 0.3% to 5.3% compared to
                accretion to Umpqua book value implied in the Merger of 0.7%.

                analysis assumes no adjustment to book value for options but

PRO FORMA MERGER ANALYSIS

        Davidson reviewed projections prepared by VRB management for year-end
2000 and 2001, and performed an arithmetic adjustment to year-end 2001 results
to forecast 2002 results. This adjustment consisted of applying the same
percentage increase or decrease between 2000 and 2001 to the change between 2001
and 2002.

        Davidson also reviewed projections prepared by Umpqua management for
year-end 2000, 2001 and 2002 and prepared a combined forecast based upon the
information prepared by VRB and Umpqua managements and the adjustment that
Davidson made for the VRB's projected 2002 results.

        Davidson did not use the forecasts and projections in analyzing the
exchange ratio, but provided this information to VRB as an illustrative overview
of the proposed combined corporation. The most striking difference in the
performance of the combined entity and the historic record of VRB is that the
rate of growth of assets, loans and deposits is substantially greater than the
growth historically at VRB.

        This analysis ignored any expense reductions or synergies that may be
gained as a result of the merger. These projections assume that there will be no
substantial shift in future economic, financial market, competitive and
regulatory conditions, all of which are difficult or impossible to predict and
largely beyond the control of both parties to this merger.

        Actual results achieved by the combined company following the merger may
vary from this and other forecasts, and the variations may be material. Like all
forward-looking statements, this analysis produces results that are inherently
uncertain.

        Davidson's opinion is directed only to the VRB board and the question of
whether the exchange ratio is fair from a financial perspective and does not
constitute a recommendation to any VRB stockholder to vote in favor of the
Merger.

        Davidson acts as a market maker in VRB and Umpqua common stock. In the
ordinary course of Davidson's business, Davidson and its affiliates may actively
trade securities of VRB and Umpqua for their own and for the accounts of
customers, and may, therefore, at any time hold a long or short position in such
securities.

        VRB retained Davidson to deliver a fairness opinion in connection with
the merger. VRB agreed to pay Davidson a total fee of $100,000, plus expenses.
VRB also agreed to indemnify Davidson and its officers and employees against
certain liabilities in connection with its services under the engagement letter.


                                   THE MERGER

        The following description of the Merger is not complete and is qualified
in its entirety by reference to the Merger Agreement attached as Appendix I.
Shareholders are urged to read the Merger Agreement in its entirety.


                                       34
<PAGE>   41

GENERAL

        The Merger Agreement provides that VRB will be merged with and into
Umpqua. Upon consummation of the Merger (the "Effective Date"), the separate
corporate existence of VRB will cease, Umpqua will be the continuing company and
the shareholders of VRB will become shareholders of Umpqua. At the same time,
Valley of the Rogue Bank will merge with and into South Umpqua Bank and the
continuing bank will change its name to "Umpqua Bank."

CONVERSION OF VRB COMMON STOCK; EFFECTS ON UMPQUA SHAREHOLDERS

        Conversion of VRB Common Stock. At the Effective Date, each share of VRB
common stock will be converted into the right to receive 0.8135 Shares of Umpqua
common stock (the "Exchange Ratio").

        The Exchange Ratio could increase to as high as 0.8500 if:

        -       The average closing price of Umpqua common stock is below $6.75,

        -       That average price, compared to the Nasdaq Bank Index, has
                declined ten percentage points more than the corresponding
                change in the Bank Index, and

        -       Umpqua elects to increase the Exchange Ratio after receiving
                notice from VRB that it otherwise intends to terminate the
                Merger.

        More specifically, if the average closing price of Umpqua common stock
for the twenty consecutive trading days ending on and including the tenth
calendar day preceding the projected Effective Date is less than $6.75 per share
and if the difference between that average closing price and $8.15 (the price
per share on August 11, 2000), expressed as a percentage, obtained by dividing
that difference by $8.15, exceeds the Index Differential (defined below) by more
than ten percentage points, the VRB Board of Directors would have the option
(but not the obligation) to terminate the Merger Agreement unless Umpqua chooses
in its sole discretion to increase the Exchange Ratio by an amount determined by
multiplying 0.8135 by $6.75 and dividing that product by the average closing
price. In no event would the Exchange Ratio calculated by this formula be
greater than 0.8500. If the average Umpqua closing price is less than $6.10 and
the difference between that price and $8.15, expressed as a percentage, exceeds
the Index Differential by more than ten percentage points, the VRB Board of
Directors nonetheless have the option (but not the obligation) to terminate the
Merger Agreement.

        The "Index Differential" is calculated by dividing the Nasdaq Bank Index
for the twenty consecutive trading days ending on and including the tenth
calendar day proceeding the projected Effective Date by 1,588.3, which was the
average Bank Index for the twenty trading days prior to August 11, 2000. The
Nasdaq Bank Index is a broad-based capitalization-weighted index of domestic and
foreign common stocks of banks that are traded on the Nasdaq National Market as
well as the Small Cap Market.

        The Exchange Ratio is a fixed ratio entitling VRB shareholders to
receive 0.8135 shares of Umpqua stock. The potential adjustment is intended to
protect the value VRB expects to receive in the Merger by giving the VRB Board
the option to terminate the transaction if the market value of Umpqua common
stock suffers a decline that is disproportionate to a decline in the market of
bank stocks in general. Should that occur, Umpqua may, in its sole discretion,
increase the Exchange Ratio to provide additional shares to VRB (up to a maximum
Exchange Ratio of 0.8500) and if it chooses to do so, the Merger would proceed.
However, if the average closing price for Umpqua



                                       35
<PAGE>   42

common stock is below $6.10 and that decline exceeds any decline in the Bank
Index by more than ten percentage points, the VRB Board of Directors could
nonetheless terminate the Agreement.

        The following are examples of the Exchange Ratio if both triggering
conditions were to occur and Umpqua were to elect to increase the Exchange Ratio
in accordance with the Merger Agreement:

</TABLE>


        Effect on Umpqua Shareholders. At the Effective Date, each share of
Umpqua common stock will continue as one share of the combined company.

        Share Ownership at Effective Date. As a result of the Merger, former
Umpqua shareholders will hold approximately 53% of the shares and former holders
of VRB shareholders will hold approximately 47% of shares of the combined
company.

        Cash for Fractional Shares. No fractional shares of Umpqua common stock
will be issued in the Merger. Each VRB Shareholder who otherwise would be
entitled to a fraction of a share of Umpqua common stock will be paid the cash
value of such fractional share, valued as of the Effective Date.

EXCHANGE OF STOCK CERTIFICATES

        Manner of Exchange - VRB Certificates. Umpqua has selected ChaseMellon
Shareholder Services as exchange agent ("Exchange Agent") to effect the exchange
of certificates representing shares of VRB common stock in connection with the
Merger. Promptly after the Effective Date, the Exchange Agent will mail to each
VRB shareholder a notice that the Merger has been completed. The notice will be
accompanied by a certificate transmittal form that will contain instructions as
to the procedure for the surrendering VRB certificates in exchange for Umpqua
stock certificates.

        VRB SHAREHOLDERS SHOULD NOT SEND THEIR STOCK CERTIFICATE TO THE EXCHANGE
AGENT UNTIL THEY HAVE RECEIVED A CERTIFICATE TRANSMITTAL FORM. CERTIFICATES
SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY.

        Rights of Holders of VRB Stock Certificates Prior to Surrender. Until
certificates representing shares of VRB common stock are surrendered, no
dividends or other distributions declared or payable to holders of record of
Umpqua common stock as of any time subsequent to the Effective Date will be paid
to the holder of any unsurrendered certificate. Such holder will have other
rights as an Umpqua shareholder, including the right to vote on any matter
submitted to the shareholders for their approval.

        Certificates for Umpqua Common Stock. All shares of Umpqua common stock
issued and outstanding at the Effective Date will remain issued and outstanding
as shares of Umpqua and no action is required of any Umpqua shareholder (other
than the vote solicited hereby) to conclude the Merger.



                                       36
<PAGE>   43

        Lost Certificates. In the event that any certificates representing VRB
common stock or Umpqua common stock have been lost, stolen, or destroyed, the
shareholder must submit an affidavit of that fact and, if required, post a
reasonable bond as indemnity against any claim that may be made against Umpqua
with respect to that certificate.

TREATMENT OF OUTSTANDING STOCK OPTIONS

        As of ______________, 2000, there were _________ unexercised options
outstanding under various employee and director stock option plans of VRB
(collectively, the "VRB Option Plans") to purchase shares of VRB common stock at
prices ranging from $______ to $_____ per share.

        On the Effective Date, Umpqua will assume VRB's obligations with respect
to each outstanding VRB option, whether or not then exercisable. Thereafter, (a)
each option may be exercised only for Umpqua common stock, (b) each option will
become an option to purchase the number of shares of Umpqua common stock equal
to the Exchange Ratio multiplied by the number of shares of VRB common stock
subject to such option and, (c) the exercise price per share of the Umpqua
common stock will be an amount computed by dividing the exercise price per share
of VRB common stock by the Exchange Ratio. All previously outstanding Umpqua
stock options will remain outstanding and are unaffected by the Merger.

MERGER OF SUBSIDIARY BANKS; NAME CHANGE

        Immediately following the Effective Date, Valley of the Rogue Bank will
merge with South Umpqua Bank, which will change its name to "Umpqua Bank."

RESULTING BOARD OF DIRECTORS OF UMPQUA AND UMPQUA BANK

        The Merger Agreement provides that the current Umpqua Board of Directors
will designate six individuals, and the current VRB Board of Directors will
designate five individuals, to serve as directors of the combined company
commencing on the Effective Date. These same individuals will also serve as
directors of the combined bank. The Umpqua Board of Directors is a classified
board of directors with the directors serving terms of 1, 2 or 3 years. Two VRB
directors will be appointed to serve a 3-year term, two individuals to serve
2-year terms, and one to serve a 1-year term (each case the length of term being
reducible to reflect the annual meeting schedule of Umpqua shareholders). The
Umpqua designees will similarly be divided evenly among each of the three terms.

        The following persons have been selected to serve the terms designated.
A vote in favor of the Merger will constitute a vote to elect these persons to
the Umpqua Board to serve following the Merger.

        If, prior to the Effective Date, any of the foregoing persons becomes

director following the Effective Date and before the second annual meeting of
the combined company, the Board will fill any vacancy in accordance with
Umpqua's Bylaws, as restated in connection with the Merger, and as required by
the governing provisions of the Oregon law, based on nominations by affirmative
votes of a majority of the remaining VRB-designated directors (if the vacancy
relates to a VRB-designated director) or by Umpqua-designated directors (if the
vacancy relates to an Umpqua-designated director).

        Governance Limitation. As of the Effective Date, the bylaws of Umpqua
will be amended and restated to provide that prior to the second anniversary of
the Effective Date, directors may not take any of the following actions without
the approval of two-thirds of the directors:

        -       A decision to change the number or composition of the Umpqua
                Board of Directors or Umpqua Bank except in connection with a
                plan of merger or other acquisition;

        -       Enter into a merger, share exchange, sale or acquisition of all
                or substantially all of the assets or similar transaction where
                the Umpqua shareholders would hold less than 50% of the voting
                securities of the combined entity following the transaction;

        -       Nominate or solicit proxies for the election of nominees to
                succeed a previous VRB-designated director; or

        -       Enact a resolution or amendment which would change the articles
                of incorporation or bylaws of Umpqua or Umpqua Bank in a manner
                that would reduce the percentage voting requirement or the
                duration of these restrictions.

CONDUCT OF BUSINESS PENDING THE MERGER

        Umpqua and VRB have agreed that, prior to the Effective Date, each will
continue to conduct its respective business only in the ordinary course, and use
all reasonable efforts to preserve its present business organizations, retain
the current management, and preserve the goodwill of all persons with whom it

of the other party, neither party will engage in transactions affecting its
capitalization, assets or obligations, including declaring extraordinary

transaction with another party. Further, neither party may provide non-public
information to any other person in connection with a possible alternative
transaction except to the extent specifically authorized by its board of
directors in good faith and in the exercise its fiduciary duties based upon
advice of its legal counsel. Each party must notify the other if it receives any
alternative acquisition transaction.

EMPLOYMENT RELATED MATTERS

        Umpqua has agreed to provide VRB and Valley of the Rogue Bank employees
with compensation and benefits packages and employment terms no less favorable
than those made available to Umpqua and Umpqua Bank employees of similar tenure
and responsibilities. For purpose of participation in Umpqua bonus plans, profit
sharing plans and arrangements, or similar benefits, VRB and Valley of the Rogue
Bank employees will receive credit for length of service and will be entitled to
participate in bonus compensation plans and awards following the Effective Date.

CONDITIONS TO THE MERGER

        The Merger is subject to certain conditions set forth in the Merger
Agreement. In the event that those conditions remain unsatisfied and the Merger
has not been completed by March 31, 2001, the Agreement may be terminated by
either party.

        The Merger can only occur if:

        -       VRB's and Umpqua's shareholders approve the Merger at their
                respective special shareholders' meetings;

        -       The FDIC and the Oregon Director approve the Merger of the two

                Merger; and

        -       Umpqua receives a waiver of jurisdiction from the Federal

<PAGE>   50

        Umpqua has filed applications or waiver requests with all regulatory
agencies and expects to receive the necessary approvals in due course.

        Certain other conditions must be satisfied or waived, and other events
must occur before the parties will be obligated to complete the Merger. Each
party's obligations are conditioned on satisfaction by the other parties of
their obligations under the Merger Agreement and other conditions. Specifically,
these obligations and conditions include:

        -       The representations and warranties given by each party are true
                in all material respects as of the effective date of the Merger,
                and each party has complied with its covenants in the Agreement;

        -       There has been no material adverse change in the business or
                financial condition of either party;

        -       The parties have provided one another with opinions of experts
                with respect to certain tax treatment and legal matters,
                accounting and fairness; and

        -       There are no actions or proceedings commenced or threatened
                against any party to restrain, prohibit or invalidate the
                Merger.

WAIVER OF CONDITIONS; AMENDMENT OR TERMINATION OF THE MERGER AGREEMENT

        Waiver. The Merger Agreement provides that VRB or Umpqua may waive any
condition precedent to its own obligations under the Merger Agreement, including
any default in performance of any obligation of the other or the time for
compliance or fulfillment of any obligation of the other, provided that such a
waiver is permitted by law.

        Amendment. The Merger Agreement may be amended at any time prior to the
Effective Date upon approval of each party's Board of Directors; however no
increase in the Exchange Ratio beyond 0.8500 can be made without the approval of
Umpqua shareholders and no decrease in the Exchange Ratio below 0.8135 can be
made without the approval of VRB shareholders.

        Termination. The Merger Agreement may be terminated, and the Merger
abandoned, at any time prior to the Effective Time:

                (a)     By the mutual consent of both VRB and Umpqua for any
                        reason;

                (b)     By either VRB or Umpqua any time after March 31, 2001,
                        if the Merger has not been consummated by the date
                        through no fault of the terminating party;

                (c)     By either VRB or Umpqua in the event of a material
                        breach by the other party of its representations,
                        warranties, covenants, or agreements contained in the
                        Merger Agreement;

                (d)     By VRB or Umpqua upon advice of their respective legal
                        counsel that the fiduciary duties of the directors of
                        such company require that the company do so (a
                        "Fiduciary Out");

                (e)     By VRB if (i) the twenty day average closing price of
                        Umpqua common stock ten days prior to the anticipated
                        Effective Date is less than $6.75, and (ii) the
                        difference between such average closing price and $8.15,
                        expressed as a percentage of $8.15, is more than ten
                        percentage points greater than the change in the Nasdaq
                        Bank Index and Umpqua elects not to increase the


                                       44
<PAGE>   51

                        Exchange Ratio (see "THE MERGER - Conversion of VRB
                        Common Stock"); or

                (f)     By VRB if (i) the average closing price (as determined
                        above) of Umpqua common stock is less than $6.10 and
                        (ii) the decline in the average price of Umpqua common
                        stock, expressed as a percentage of $8.15, exceeds the
                        change in the Nasdaq Bank Index by more than ten
                        percentage points.

        Effect of Termination. If the Agreement is terminated as a result of a
party's shareholders' failure to approve the Merger or the exercise of a
Fiduciary Out by such party, that party must pay the reasonable expenses
incurred by the other party in connection with negotiating and performing its
obligations under the Agreement. In addition, if the Agreement is terminated
because of a Fiduciary Out or failure to obtain shareholder approval, and the
terminating party enters into an alternative acquisition transaction (as
defined) prior to December 31, 2001 and (i) the alternative acquisition
transaction had been proposed prior to the date of the special shareholders'
meeting or (ii) at the time of the shareholder meeting the terminating company
or its directors had materially failed to comply with their covenants under the
Merger Agreement, that party will pay a $3,000,000 termination fee to the
non-terminating party. If the non-terminating party exercises the stock option
agreement, it would waive the right to receive the additional cash payment (see
"THE MERGER - Umpqua and VRB Stock Option Agreements").

EFFECTIVE DATE OF THE MERGER

        The Merger will become effective when Umpqua files the articles of
merger with the Secretary of State of the State of Oregon. The Effective Date
will occur as promptly as practical after the date upon which all the conditions
to the Merger are satisfied or duly waived or at such time and date as VRB and
Umpqua agree. The parties currently anticipate that the Merger will be completed
prior to year-end 2000.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

        General. Certain members of management, and certain members of the VRB
and Umpqua Board of Directors, may be deemed to have interests in the Merger in
addition to their interests as shareholders. The Board of Directors of VRB and
of Umpqua were aware of these interests and considered them, among other
matters, in approving the Merger.

        Continuation of Certain Persons as Directors and Executive Officers. The
Merger Agreement provides that six current Umpqua directors and five current VRB
directors will serve after the Effective Date as directors of Umpqua and Umpqua
Bank. Those individuals are identified above under "THE MERGER -- Board of
Directors and Certain Executive Officers of the Combined Company." Also as noted
elsewhere, all the executive officers of both companies are expected to continue
following the Effective Date, some with new titles and responsibilities and at
higher compensation levels as noted below.

        Executive Employment Agreements. Pursuant to the recommendation of
management of Umpqua, and upon the approval of the respective Boards of
Directors of Umpqua and VRB, Umpqua has entered into executive employment
agreements with three VRB executives, William A. Haden, Brad Copeland and Kathy
Peckham. The employment agreements are conditioned upon completion of the Merger
and will become effective as of the Effective Date, replacing their current
employment or severance agreements.



                                       45
<PAGE>   52

        Each new executive employment agreement provides that the executive
shall be employed for a two year term following the Effective Date in the
position specified above. Messrs. Haden and Copeland will receive base salaries
of $192,300 and $166,700 a year, respectively, and Ms. Peckham will receive a
base salary of $83,300 per year. Although Felice Belfiore has elected not to
enter into an employment agreement with Umpqua, she will continue as an employee
of the surviving company and her base salary will be $91,700. In addition, Mr.
Haden will have an opportunity to earn up to 30% of his base salary each year as
a cash bonus pursuant to an incentive compensation plan to be developed and
approved by the Umpqua Board of Directors. Mr. Copeland, Ms. Belfiore and Ms.
Peckham have an opportunity to earn up to 20% of their base salaries as a cash
bonus pursuant to that plan. The employment agreements also provide for other
perquisites consistent with those afforded to Umpqua's other senior executives
and relocation expenses for those required to move.

        Under the employment agreements, if an executive's employment is
terminated prior to the expiration of the two year term without cause (as
defined) or terminated by the executive for good reason (as defined), the
executive will be entitled to one year's compensation, paid monthly, so long as
the executive does not compete (as defined) with Umpqua during that payment
period. Executives are also entitled to a severance equal to three months base
salary (six months with respect to Mr. Haden) if the executive terminates
employment for any reason between 180 days and one year after the Effective
Date. Any severance payment would be conditioned upon the executive not
competing with Umpqua during the payment period.

        The employment agreements also provide for severance payments under
certain circumstances in connection with a change of control (as defined) after
the initial term of their employment contract. Generally, if the executive is
terminated without cause, or the executive terminates his or her employment for
good reason, the executive is entitled to severance equal to one years'
compensation (six month's compensation if the termination occurs more than six
months, after the change of control). The executive is also entitled to
severance payments of three month's compensation (six months with respect to Mr.
Haden) if the executive voluntarily resigns between 180 days and one year after
the date of the change of control. The executive would be entitled to severance
only if they do not compete with Umpqua or its successor during the payment
period. Severance payable upon voluntary resignation would be extended to an
additional three months (six months with respect to Mr. Haden) if the executive
is not employed during that extended severance period.

        Control Payment and Accelerated Right to Exercise Stock Options.
Pursuant to William A. Haden's current employment contract, he is entitled to a
payment of $188,000 in the event of a change of control. Completion of the
Merger would be a change of control, and Mr. Haden will be entitled to receive
payment on or immediately after the Effective Date. Further, certain stock
option agreements held by Mr. Haden, Brad Copeland and Felice Belfiore permit
them to exercise their outstanding stock options not otherwise vested in the
event of a change of control. With respect to Mr. Haden, this early right to
exercise would apply to 80,538 shares at an average exercise price of $5.22,
with respect to Mr. Copeland and Ms. Belfiore, 20,800 shares at an exercise
price of $8.17. If these executives choose not to exercise their stock options
at the Effective Date, the options would revert to their existing vesting
schedule and would convert to options to purchase Umpqua stock in the same
manner as other VRB options. With respect to all other options outstanding under
the VRB stock option plans, the VRB Board of Directors could permit the grantees
a 30 day period prior to the Effective Date to exercise all stock options
(vested or not) in lieu of any continuing rights under the outstanding option
agreements. However, such



                                       46
<PAGE>   53

an election by the Board of Directors might preclude the ability of the Merger
to be accounted for under the pooling-of-interest methods and as a result, the
Board has indicated they do not intend to make such an election.

COMMITMENTS OF DIRECTORS

        Each VRB and Umpqua director has agreed to use his or her best efforts
to complete the Merger, recommend (subject to their fiduciary duties) approval
of the Merger by their shareholders and vote all their shares in favor of the
Merger. Further, except with the consent of Umpqua, each non-employee director
has agreed that for two years following service on the Board of Directors of
Umpqua or VRB, he or she will not be associated in any way with any financial
institution with branches competitive with Umpqua or with respect to directors
not serving after the Effective Date, competition with the branches of either
South Umpqua Bank or Valley of the Rogue Bank, as the case may be. Umpqua has
granted limited exceptions to these obligations for two VRB directors, April
Sevcik and Thomas Anderson. Each of the Umpqua and VRB Directors has also agreed
to vote all his or her shares for the Merger and in favor of the director
candidates nominated by the Umpqua Board of Directors for election or
re-election in accordance with the Merger Agreement.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

        The Merger is intended to qualify as a tax-free reorganization under
Section 368(a)(1)(A) of the Internal Revenue Code for federal income tax
purposes. A condition of the Merger is a receipt by the parties of an opinion
from Foster Pepper & Shefelman LLP that the Merger will constitute a tax-free
reorganization for federal and Oregon income tax purposes. That opinion will not
bind the Internal Revenue Service or preclude the Internal Revenue Service from
adopting a contrary position. The opinion will be based upon certain facts and
assumptions and specific representations and assurances made by Umpqua and VRB.

        The federal income tax discussion set forth below may not apply to
particular categories of Umpqua and VRB shareholders subject to special
treatment under the federal income tax laws, such as foreign holders, and
shareholders whose stock was acquired as compensation. In addition, there may be
relevant state, local or other tax consequences, none of which are described
below. Shareholders are urged to consult their tax advisors to determine the
specific personal tax consequences of the Merger, including the applicability
and effect of foreign, state, local and other tax laws.

        The Foster Pepper & Shefelman LLP opinion will state that the
transaction contemplated by the Merger Agreement will be a reorganization within
the meaning of Section 368(a) of the Code; that the parties to the Agreement and
to the Plans of Merger will each be "a party to a reorganization" within the
meaning of Section 368(b) of the Code; that no taxable gain or loss will be
recognized by the shareholders of VRB; that the basis in the Umpqua common stock
to be received by the recipients will be the same as the basis in their VRB
common stock; and that, provided the stock exchanged was held as a capital asset
on the Effective Date, the holding period of the Umpqua common stock to be
received will include the holding period of the VRB common stock previously
held, prior to the Effective Date.

ACCOUNTING TREATMENT

        It is anticipated that the Merger will be accounted for as a
pooling-of-interests for accounting and financial reporting purposes. Under this
method of accounting, recorded assets and liabilities of Umpqua and VRB are
carried forward at their previously recorded amounts; income of the combined
company will include income of Umpqua and VRB for the entire year in which the


                                       47
<PAGE>   54

Merger occurs; and the reported income of the separate companies for prior
periods will be combined. No recognition or amortization of goodwill arising
from the Merger is required of any party to the Merger. Under the Merger
Agreement, it is a condition to the obligations of the respective parties to
consummate the Merger that they shall have received a letter from Deloitte &
Touche LLP that the Merger will qualify for pooling-of-interests treatment.

        The unaudited pro forma combined financial information contained in this
Proxy Statement has been prepared using the pooling-of-interests accounting
method to account for the Merger. See "Unaudited Pro Forma Combined Financial
Statements"

NO DISSENTERS' RIGHTS

        Under applicable Oregon law, shareholders do not have the right to
dissent from the Merger and obtain payment for the appraised value of their
shares.

RESALES OF STOCK BY AFFILIATES OF VRB

        The Umpqua common stock to be issued in the Merger will be freely
transferable by VRB shareholders, except for those persons deemed to be VRB
affiliates (controlling persons), such as all directors, executive officers and
holders of more than 10% of VRB's outstanding stock immediately prior to the
Merger. VRB affiliates may not sell their Umpqua shares received in the Merger
except pursuant to an effective registration statement under the Securities Act
of 1933, as amended, or pursuant to the provisions of Rules 144 and 145 under
the Securities Act, unless in the opinion of counsel reasonably satisfactory to
Umpqua, those shares may be sold pursuant to an exemption from registration.

        In addition, to permit the Merger to be accounted for as a
pooling-of-interests, VRB affiliates may not sell any of their VRB shares for a
period beginning 30 days prior to and continuing through the effective date of
the Merger, nor may they sell any Umpqua shares received in the Merger until
after Umpqua publishes financial results covering at least 30 days of combined
operations. Certificates issued in the Merger to VRB affiliates will bear
legends reflecting those restrictions.

EXPENSES

        The Merger Agreement provides, in general, that VRB and Umpqua will each
pay their own expenses in connection with the Merger including fees and expenses
of their own financial and other consultants, accountants, and counsel except
under certain termination events. Upon completion of the Merger, other expenses,
including severance payments, will be incurred paid by the combined company.

UMPQUA AND VRB STOCK OPTION AGREEMENTS

        At the time the Merger Agreement was signed, Umpqua executed and
delivered the Umpqua Option Agreement, pursuant to which Umpqua granted VRB an
option to purchase up to 19.9% of the outstanding Umpqua common stock under
specified conditions. At the same time, VRB executed and delivered the VRB
Option Agreement, pursuant to which VRB granted to Umpqua an option to purchase
up to 19.9% of the outstanding shares of VRB common stock under specified
conditions. Umpqua and VRB approved and entered into the Option Agreements to
induce each other to enter into the Merger Agreement. One effect of the Option
Agreements is to increase the likelihood that the Merger will be consummated by
making it more difficult and more expensive for another party to obtain control
of or acquire either Umpqua or VRB. Umpqua and VRB believe that the exercise of
an Issuer Option (as defined below) would likely bar any acquiror



                                       48
<PAGE>   55

of the Issuer (as defined below) from accounting for an acquisition of, or
merger with, the Issuer using the pooling-of-interests accounting method for a
period of up to two years.

        Except as otherwise noted below, the terms and conditions of the Option
Agreements are identical in all material respects. For the purposes of this
section, except as otherwise noted, (a) Umpqua and VRB, as issuer of their
common stock upon exercise of the Umpqua Option and the VRB Option,
respectively, are sometimes individually referred to as the "Issuer," (b) Umpqua
and VRB, as the holder of the VRB Option and the Umpqua Option, respectively,
are sometimes individually referred to as the "Optionee," (c) each of the
options granted under the respective Option Agreements is sometimes referred to
as the "Issuer Option," and (d) Umpqua common stock and VRB common stock are
sometimes individually referred to as the "Issuer common stock."

        The Umpqua Option provides for the purchase by VRB of up to 1,517,500
shares (the "Umpqua Option Shares" or the "Issuer Option Shares," as the case
may be) of Umpqua common stock at an exercise price of $8.15 per share (the
average of the closing prices per share of Umpqua common stock for the twenty
trading days ended on August 11, 2000), subject to adjustment as provided in the
option agreement, payable in cash. The Umpqua Option Shares would represent
approximately 19.9% of the Umpqua common stock issued and outstanding on August
14, 2000.

        The VRB Option provides for the purchase by Umpqua of up to 1,653,450
shares (the "VRB Option Shares" or the "Issuer Option Shares," as the case may
be) of VRB common stock at an exercise price of $5.07 per share (the average of
the closing prices per share of VRB common stock for the twenty trading days
ended on August 11, 2000), subject to adjustment as provided in the option
agreement, payable in cash. The VRB Option Shares would represent approximately
19.9% of the VRB common stock issued and outstanding on August 14, 2000.

        The number of shares and option price of Issuer common stock subject to
the Issuer Option would be appropriately adjusted in the event of any stock
dividends, split-ups, mergers, recapitalization, combinations, subdivisions,
conversions, exchanges of shares, or the like, relating to the Issuer.

        The Optionee or any other holder or holders of the Issuer Option (as
used in this section, collectively, the "Holder") may exercise the Issuer
Option, in whole or in part, subject to regulatory approval and certain notice
requirements if:

                -       The Issuer or its Board of Directors enters into an
                        agreement or recommends to their shareholders an
                        agreement which would result in an acquisition or merger
                        of the Issuer or any of its assets or securities, the
                        result of which the Issuer's shareholders would hold
                        less than 50% of the stock of the surviving company;

                -       Any person who does not currently own 10% of the Issuer
                        acquires beneficial ownership of more than 10% of the
                        voting securities of the Issuer (25% if "control" is not
                        presumed); or

                -       With certain exceptions, the Issuers' Board of Directors
                        fails to recommend or withdrawals its recommendation of
                        the Merger or the shareholders of the Issuer fail to
                        approve the Merger after a person announces publicly or
                        communicates in writing an alternative acquisition
                        transaction (as defined) or communicates an intention to
                        acquire



                                       49
<PAGE>   56

                        25% or more of the voting shares of the Issuer or
                        substantially change the composition of its Board of
                        Directors.

        The Optionee cannot exercise the Option Agreement if the Optionee has
elected to receive the three million dollar ($3,000,000) termination fee
provided for in the Merger Agreement.


        HISTORICAL AND UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

        The following unaudited pro forma combined financial statements give
effect to the Merger of Umpqua and VRB on a pooling-of-interests basis. The
unaudited pro forma combined balance sheet assumes the Merger took place on June
30, 2000. The unaudited pro forma combined statements of income assume the
Merger was consummated as of the beginning of the first period presented.

        These unaudited pro forma combined financial statements should be read
in conjunction with the historical financial statements and the related notes
thereto to Umpqua and VRB included in this Proxy Statement.

        The unaudited pro forma statements of income are not necessarily
indicative of operating results which would have been achieved had the Merger
been consummated as of the beginning of the first period presented and should
not be construed as representative of future operations.

        Notes to Unaudited Pro Forma Combined Financial Statements:

        Note A. Basis of Presentation. The unaudited pro forma financial
information has been prepared under the pooling-of-interests method of
accounting and is based on the historical financial statements of Umpqua and VRB
assuming the Merger had been concluded at the beginning of the periods
indicated. Certain amounts in the historical financial statements of VRB have
been reclassified to conform to Umpqua's historical financial presentation. The
pro forma adjustments represent management's best estimate based on available
information at this time. These adjustments may change as additional information
becomes available.

        Note B. Merger and Integration Costs. In connection with the Merger, the
combined company expects to incur pre-tax merger related costs of $2 million
($1.6 million, after tax), $1.0 million of which is expected to occur at the
Effective Date with the remaining $1.0 million to be incurred within the
following six months. The estimated costs include $500,000 in severance
payments, $200,000 in conversion costs (primarily system reconfiguration and
enhancements, customer forms, and other communications), $1.0 million in
professional costs (primarily legal and accounting costs, investment banking
fees and marketing campaigns), and $300,000 in write-off of duplicate equipment
and other capital assets.

        These amounts, net of tax, have been reflected in the Unaudited Pro
Forma Combined Balance Sheet as of June 30, 2000. These adjustments are not
reflected in the Unaudited Pro Forma Combined Statements of Income, as they are
not expected to have a continuing impact on Umpqua. These amounts will be
recorded in the financial statements in accordance with generally accepted
accounting principles.

        Note C. Capital. In conjunction with the transaction, Umpqua will
exchange 0.8135 shares of Umpqua stock for each share of common stock of VRB.
VRB had 8,301,361 shares outstanding as of June 30, 2000. The common stock has
been adjusted to reflect the stated value of Umpqua stock to be issued, with a
related adjustment to retained earnings. Pro forma combined retained earnings
reflects the adjustments for anticipated merger-related costs as discussed
above.

        Note D. Operating Costs Savings and Revenue Enhancements. Umpqua expects
to achieve pre-tax savings of $1.2 million through consolidation of data
processing and back office functions, and reduced professional fees.
Approximately $800,000 of the operating cost savings are expected to be achieved
by the end of 2001, with the remainder achieved in 2002. In addition, pre-tax
revenue enhancement opportunities have been identified amounting to $400,000,
less $100,000 related to possible deposit run-off. No adjustment has been
included in the unaudited pro forma combined financial information for the
anticipated cost savings or revenue enhancements. There can be no assurance that
anticipated operating cost savings or revenue enhancements will be achieved in
the amounts or at the times anticipated.


                           UMPQUA HOLDINGS CORPORATION
                             2000 STOCK OPTION PLAN

APPROVAL OF 2000 STOCK OPTION PLAN BY UMPQUA SHAREHOLDERS

        In 1995, Umpqua adopted, and its shareholders approved, the 1995 Stock
Option Plan that provided for the grant of options to employees, directors and
other individuals who provide services of value to Umpqua. To date, Umpqua has
used that plan solely to grant non-statutory stock options (options that do not
qualify as incentive stock options under the Internal Revenue Code) to executive


                                       57
<PAGE>   64

officers and a other key employees. The 1995 Plan authorized the issuance of up
to 1,150,000 shares, adjusted for previous stock splits, but in no event may
options exceed 10% of the shares issued and outstanding at the time of a grant.

        On the Effective Date, there will be approximately 234,000 shares
available for future grants after substitute options are issued to the VRB
option holders pursuant to the Merger Agreement. The remaining authorized shares
would be expected to be exhausted in the near future. Accordingly, Umpqua's
Board of Directors believes it necessary and appropriate to provide for
additional shares for which options may be granted in the future. Further, the
1995 Plan was adopted before the company had become a SEC reporting company and
does not include provisions considered appropriate for plans of public
companies. Accordingly, the Board of Directors has approved the new plan to be
effective immediately following the Effective Date of the Merger. At that time,
the 1995 Stock Option Plan would be terminated and no future grants would be
made under the 1995 Plan.

        Umpqua believes that it is important and beneficial to the company to
give employees an opportunity to participate in the ownership of the company.
Equity compensation, in addition to regular salaries, enables Umpqua to attract
and retain highly qualified employees in a competitive market. Stock options
provide employees with incentives to increase productivity and profitability,
thereby enhancing shareholder value. A new stock option plan will permit the
company to continue the program of equity participation and long term
incentives.

        The Umpqua's Board of Directors has approved, and is recommending to its
shareholders, the adoption of the 2000 Stock Option Plan. The more important
features of the plan are discussed below, but you should read the entire plan
before you vote. A copy of the 2000 Plan is attached as Appendix IV to this
Proxy Statement.

        The 2000 Plan provides for the issuance of up to 1,000,000 shares of
common stock upon exercise of incentive stock or nonqualified stock options. In
the event any option granted expires without being exercised, the unexercised
shares formerly subject to that option would again become available for options
to be granted. The 2000 Plan further provides that no grants may be made when
the total options outstanding on the Effective Date plus the future grants under
the 2000 Plan exceed 10% of the then-outstanding shares.

        The 2000 Plan will become effective immediately following the Effective
Date of the Merger, subject to approval by Umpqua shareholders, and will
terminate 10 years thereafter. No further options would be granted under the
existing 1995 Plan. The Plan will be administered by a committee of the Board of
Directors or, if no committee is appointed, by the full Board of Directors.

        Each person receiving an option must execute a written agreement which
sets forth the terms and conditions of the option. Options are exercisable for a
set period of time not to exceed ten years from the date of the grant, and may
be subject to a vesting schedule, becoming incrementally exercisable over a
period of time.

        In the event of a transaction involving a change of control of the
company, such as a merger or acquisition in which the company's shareholders own
less than a majority of the shares outstanding after the transaction, option
holders would be immediately entitled to exercise all of their options,
notwithstanding any vesting schedule, unless the terms of the transaction make
adequate provision for the continuation of the rights of such option holders.



                                       58
<PAGE>   65

        Options may be exercised only while the recipient is employed or is
serving as a director, or within 30 days after termination of service unless the
person is disabled or dies, in which case all options terminate after one year
from the date of the disability or death. Options are not transferable except
(i) by will or the laws of descent and distribution, or (ii) with respect to
nonqualified stock options, by gift to family members with the consent of the
committee.

        Options are designated as either "Incentive Stock Options," as defined
in Section 422 of the Internal Revenue Code, or "Nonqualified Stock Options" and
are exercisable at a per share price not less than 100% of the fair market value
of the common stock on the date of the grant. Incentive stock options granted to
any person with a beneficial ownership of 10% or more of the outstanding shares
must be exercisable at a per share price not less than 110% of the fair market
value of the common stock on the date of the grant. The 2000 Plan permits, at
the discretion of the committee, the option holder to pay the exercise price of
any options with cash, company stock held by the option holder for at least six
months, or by the application of shares that could be received upon exercise of
the options (a "net" exercise) with such shares valued at the difference between
the option exercise price and the fair market value of the underlying shares.
The 2000 Plan also permits broker-assisted cashless exercises of stock options.

        Nonqualified stock options do not result in income to the grantee under
federal income tax law currently in effect until the option is exercised. At the
time of exercise of a nonqualified stock option, the recipient of the option
will realize ordinary income, and the company will be entitled to a deduction
for tax purposes, in the amount by which the market value of the shares issued
on exercise of the option exceeds the exercise price.

        Incentive stock options have no tax consequences for the option
recipient or the company upon grant or exercise, except for possible application
to the option recipient of the alternative minimum tax under certain
circumstances. Upon sale of the shares received from the exercise of incentive
stock options, any gain realized is treated as capital gain if two years have
elapsed from the date of the grant and one year has elapsed from the date of
exercise. If these holding periods are not satisfied, the sale is deemed a
disqualifying disposition, and that portion of any gain realized, which is
represented by the difference between the exercise price and the fair market
value of the shares as of the date of exercise of the option, is treated as
ordinary income and the company will be entitled to a corresponding compensation
expense deduction for income tax purposes if certain conditions are satisfied.


                            INFORMATION ABOUT UMPQUA

INTRODUCTION

        Umpqua Holdings Corporation was formed in March 1999 to be a holding
company of South Umpqua Bank. In March 2000, Umpqua became a financial holding
company under the newly enacted Gramm-Leach-Bliley Act. As a financial holding
company, Umpqua may engage in non-banking activities such as securities and
insurance sales, without further approval from the Federal Reserve Board.

        Umpqua, headquartered in Roseburg, Oregon, engages primarily in the
business of commercial and retail banking and the delivery of retail brokerage
services. It provides a wide range of banking, asset management, mortgage
banking, and other financial services to corporate, institutional and individual
customers through its wholly owned banking subsidiary South Umpqua Bank. It also
provides retail investment brokerage service through its wholly owned subsidiary


                                       59
<PAGE>   66

Strand, Atkinson, Williams & York, Inc. Umpqua and its subsidiaries are subject
to the regulations of certain national and state agencies and undergo periodic
examinations by those regulatory agencies.

        South Umpqua Bank is one of the most innovative community banks in the
United States, combining a retail product delivery approach with an emphasis on
quality-assured personal service. South Umpqua is the fourth largest community
bank in the state of Oregon, currently operating 14 full-service stores (or
branches) in Douglas, Lane, Marion and Multnomah Counties in Oregon. At June 30,
2000, South Umpqua had assets of $411 million and deposits of $345 million.

        Since 1995, South Umpqua has transformed itself from a traditional
community bank into a community-oriented financial services retailer by
implementing a variety of retail marketing strategies to increase revenue and
differentiate itself from its competition. To establish itself as a financial
services retailer, South Umpqua has remodeled most of its branches to resemble
retail stores. These new stores incorporate "serious about service centers" that
are the focal point for customer information, and "investment opportunity
centers" providing broker-dealer services and featuring financial and investment
information in a multimedia format. The bank has introduced smaller, 1,100
square foot "neighborhood stores," which are lower cost, new format stores
located in residential areas. To monitor the quality of its customer service,
South Umpqua introduced a "return on quality" program for its sales associates
and implemented an in-house "banking college" to train its personnel in
cross-selling and effective customer service.

        Strand, Atkinson, Williams & York, Inc., a registered broker-dealer and
investment advisor with offices in Portland, Salem, Eugene, Roseburg and
Medford, offers a full range of investment products and services including:
stocks; fixed income securities (municipal, corporate, and government bonds,
CDs, money market instruments); mutual funds; annuities; options; retirement
planning; money management services; and life insurance, disability insurance
and medical supplement policies.

BUSINESS STRATEGY

        Umpqua's objective is to become the leading community-oriented financial
services retailer throughout Oregon. It intends to continue to grow its assets
and increase profitability and shareholder value by differentiating itself from
its competitors through the following strategy:

        Capitalize On Its Innovative Product Delivery System. Umpqua's
philosophy has been to develop an environment for the customer that makes the
customer's banking experience an enjoyable one. With this approach in mind,
South Umpqua developed a prototype store that offers "one-stop" shopping and
that includes distinct physical areas or boutiques, such as a "serious about
service center," an "investment opportunity center" and a "computer cafe," which
make the bank's products and services more tangible and accessible. South
Umpqua's initial prototype store was opened in 1996 in Roseburg, Oregon, a
community with historically low deposit growth. This new store, nevertheless,
captured $12 million in deposits from competitors by the end of its first year
of operation. On the basis of this initial success, the bank opened four
additional stores featuring the new format during 1997, two additional stores in
1999, and plans to open additional stores in the near future.

        Deliver Superior Quality Service. Umpqua has insisted on quality service
as an integral part of the company's culture, from the Board of Directors to new
sales associates. South Umpqua believes it was among the first banks to
introduce a measurable quality service program. Under its "return on quality"
program introduced in 1995, each sales associate's and store's performance is


                                       60
<PAGE>   67

evaluated monthly based on specific measurable factors such as the "sales
effectiveness ratio" that totals the average number of banking products
purchased by each new customer. The evaluations also encompass factors such as
the number of referrals generated for the sale of investment products, the
number of new loans and deposits generated in each store, reports by incognito
"mystery shoppers" and customer surveys. Based on scores achieved, the "return
on quality" program rewards both individual sales associates and store teams
with financial incentives. Through such programs, the bank believes it can
measure the quality of service provided to its customers and maintain employee
focus on quality customer service.

        Establish Strong Brand Awareness. As a financial services retailer,
Umpqua has devoted considerable resources to developing the "South Umpqua Bank"
brand. This campaign has included the redesign of the Umpqua's corporate logo to
emphasize its geographical origin, and promotion of the "South Umpqua Bank"
brand in advertising and merchandise bearing the South Umpqua Bank logo, such as
coffee beans, mugs, tee-shirts, hats and umbrellas. The store's unique "look and
feel" and innovative product displays help position South Umpqua as an
innovative, customer friendly retailer of financial products and services.
Umpqua believes it can build consumer preference for its products and services
through high quality service and strong brand awareness.

        Use Technology to Expand Customer Base. Although Umpqua's strategy will
continue to emphasize superior personal service, the bank will also continue to
expand user-friendly, technology-based systems to attract customers that may
prefer to interact with their financial institution electronically. Over the
past years, it has introduced technology-based services which include voice
response banking, debit cards, automatic payroll deposit programs, a "bank@home"
program, automated loan machines, advanced function ATMs and an internet web
site. Umpqua believes the availability of both traditional bank services and the
newer electronic banking services will enhance its ability to attract a broad
range of customers.

        Increase Market Share in Existing Markets and Expand Into New Markets.
As a result of its innovative retail product orientation, measurable quality
service program and strong brand awareness, Umpqua believes that there is
significant potential to increase business with current customers, to attract
new customers in its existing markets and to enter new markets. Since its
introduction of these programs, South Umpqua has experienced significant growth
in deposits within Douglas County, increasing its share of commercial bank
deposits from 21.1% at June 30, 1995 to 31.5% at June 30, 2000. In July 1996,
South Umpqua opened its first store in Eugene, Oregon, and as of June 30, 2000,
had four new-format stores in the Eugene market with total deposits of $89.0
million. Within the last year, Umpqua opened new stores in Salem and Portland,
Oregon. Umpqua plans to expand into other markets through acquisitions and the
opening of new stores.

        MARKETING AND SALES

        Umpqua's goal to increase its share of financial services in the market
areas it serves is driven by a marketing plan comprising several key components.

        Media Advertising. Over the years, Umpqua has introduced several
comprehensive media advertising campaigns. These campaigns augment the company's
goal of strengthening its brand image and heightening public awareness of its
innovative product delivery system. These campaigns, entitled "The Banking
Revolution" and "Expect the Unexpected," were designed to showcase South
Umpqua's innovative style of banking, as well as it's commitment to providing


                                       61
<PAGE>   68

quality service to its customers. "The Banking Revolution" campaign is designed
to differentiate South Umpqua from other financial institutions in its market
area, while "Expect the Unexpected" challenged them to visit the bank's stores
and experience first-hand its quality service. Both of these campaigns utilized
various forms of media, including television, radio, print, billboards and
direct mail flyers and letters.

        Retail Store Concept. As a financial services provider, Umpqua believes
that store environment is critical to successfully market and sell its products
and services. Retailers for years have displayed their merchandise within their
stores to encourage customers to purchase their products. Purchases are made on
the spur of the moment due to the products' availability and attractiveness.
South Umpqua believes this same concept can be applied to financial institutions
and accordingly displays its financial services and products through tactile
merchandising within its stores. Recent displays have included enticements for
mortgage loans, retirement accounts, investments, and checking account programs.
Unlike many financial institutions whose strategy is to discourage customers
from visiting their facilities in favor of ATMs or other forms of electronic
banking, South Umpqua encourages its customers to visit its stores, where they
are greeted by well-trained sales associates, and encouraged to browse and to
make "impulse buys." South Umpqua introduced its first "prototype" store in
mid-1996, which included such services as a 24-hour banking vestibule with an
automated loan machine, an advanced function ATM and a 24-hour self-service U.S.
Postal service center.

        Neighborhood Stores. To bring financial services to the customer in a
cost-effective way, South Umpqua has created "neighborhood stores." These
facilities are constructed near high volume traffic areas, close to neighborhood
shopping centers. These stand-alone stores are, on average, approximately 1,100
square feet in size and include all the features of the prototype store
described above. To strengthen brand recognition, all neighborhood stores are
identical in appearance. The bank currently has three neighborhood stores, all
located in the Eugene/Springfield area.

        Sales Culture. Although a successful marketing program will attract
customers to visit its stores, a sales environment and a well-trained sales team
is critical to selling Umpqua's products and services. The company believes that
its sales culture has become well established throughout the organization due to
its unique facility design and its commitment to ongoing training of sales
associates on all aspects of sales and service. South Umpqua trains its sales
associates in its own banking college and pays commissions for the sale of
Umpqua's products and services. This sales culture has helped South Umpqua
transform itself from a traditional community bank to a nationally recognized
marketing company focused on selling financial products and services.

PRODUCTS AND SERVICES

        Umpqua offers a full array of financial products to meet the banking
needs of its market area and targeted customers. To ensure the ongoing viability
of its product offerings, the company regularly examines the desirability and
profitability of existing and potential new products. To make it easy for new
prospective customers to bank with South Umpqua and access its products, the
bank introduced its "Switch Kit," which allows a customer to open their primary
checking account with South Umpqua in less than four minutes. This unique
program has helped the bank grow its number of deposit accounts from 18,200 in
1994 to 40,000 in 1999, a 100% increase. Other avenues through which customers
can access Umpqua's products include its web site and its 24-hour voice response
system.



                                       62
<PAGE>   69

        Deposit Products. South Umpqua has a traditional array of deposit
products, including non-interest checking accounts, interest-bearing checking
and savings accounts, money market accounts and certificates of deposit. These
accounts earn interest at rates established by management based on competitive
market factors and management's desire to increase certain types or maturities
of deposit liabilities. In order to increase the number of relationships with
customers and increase service fee income, the bank also introduced its line of
"Value Packages" in 1996. These packages comprise several products bundled
together to provide added value to the customer and increase the customer's ties
to the bank. South Umpqua also offers a seniors program, the "Platinum Account,"
which offers an array of banking services and other amenities such as purchase
discounts, vacation trips and seminars, to customers over fifty years old.

        Retail Investment Services. Strand, Atkinson, Williams & York, Inc.
provides a variety of investment products and services. These products include:
equity and debt securities, annuities, certificates of deposit, mutual funds,
retirement plans, life and health insurance and U.S. Government securities. The
firm has six stand-alone retail brokerage offices with 38 licensed broker-dealer
professionals. Additionally, ten South Umpqua banking stores have "Investment
Opportunity Centers" which are periodically staffed by a licensed sales
representative. Special appointments can be arranged for meetings in any store.

        Commercial Loans. South Umpqua offers specialized loans for its business
and commercial customers, including equipment and inventory financing, real
estate construction loans and SBA loans for qualified businesses. Commercial
lending is the primary focus of the bank's lending activities and a significant
portion of its loan portfolio consists of commercial loans. For regulatory
reporting purposes, a substantial portion of the bank's commercial loans are
designated as real estate loans, because the loans are secured by mortgages and
trust deeds on real property, even though the loans may be made for purposes of
financing commercial activities, such as accounts receivable, equipment
purchases and leasing.


        Real Estate Loans. Real estate loans are available for construction,
purchase and refinancing of residential owner-occupied and rental properties.
Borrowers can choose from a variety of fixed and adjustable rate options and
terms. Generally, the bank originates residential real estate loans as an
accommodation to its customers and sells most mortgages into the secondary
market. Real estate loans reflected in the loan portfolio are in large part
loans made to commercial customers that are secured by real property.

        Consumer Loans. South Umpqua provides loans to individual borrowers for
a variety of purposes, including secured and unsecured personal loans, home
equity and personal lines of credit and motor vehicle loans.

EMPLOYEES

        At June 30, 2000, Umpqua had a total of 209 full-time equivalent
employees. None of the employees are subject to a collective bargaining
agreement and Umpqua considers its relationships with its employees to be good.

1999. The Chairman received $2,750 per quarter. These amounts are payable in
shares of Umpqua Holdings Corporation stock. Shares of Umpqua Holdings
Corporation stock are purchased quarterly by Ragen MacKenzie brokerage firm for
each director. The President received no additional compensation for his service
on the Board or any of its Committees.

Limitation of Liability and Indemnification

        Under the Oregon Business Act, a corporation's articles of incorporation
may provide for the limitation of liability of directors and for the
indemnification of directors and officers, under certain circumstances. As
permitted by Oregon law, both Umpqua's and VRB's Articles of Incorporation
provide that directors are not personally liable to the corporation or its
shareholders for monetary damages for conduct as a director, except for (i) any
breach of a director's duty of loyalty to the corporation, (ii) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of the law, (iii) any distribution to shareholders which is unlawful,
or (iv) any transaction from which the director received an improper personal
benefit.

        The Articles of Incorporation of both companies also provide for
indemnification of any person who is or was made a party, or is threatened to be
made a party, to any civil, administrative or criminal proceeding by reason of
the fact that the person is or was a director or officer of the company or any
of its subsidiaries, or is or was serving at the request of the company, as a


                                       64

director, officer, partner, agent or employee or another bank or entity, against
expenses, including attorney's fees, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by the person if (i) the person
acted in good faith and in a manner reasonably believed to not be opposed to the
best interest of the company, or (ii) the act or omission giving rise to such
action or proceeding is ratified, adopted or confirmed by the company, or the
benefit thereof was received by the company. Indemnification is available under
this provision of the Articles of Incorporation in the case of derivative
actions, unless the person is adjudged to be liable for gross negligence or
deliberate misconduct in the performance of the person's duty to the company. To
the extent a director, officer, employee or agent (including an attorney) is
successful on the merits or otherwise in defense of any action to which this
provision is applicable, the person is entitled to indemnification for expenses
actually and reasonably incurred by the person in connection with that defense.

(1) Includes bonuses paid, or to be paid, during the subsequent year but
attributable to the year indicated.

(2) Perquisites and other personal benefits, if any, did not exceed the lesser
of $50,000 or 10% of the total annual salary and bonus for the named executive
officer for any of the periods indicated.

(3) In connection with the grant of stock options to Mr. Davis in 1995, the Bank
entered into a stock appreciation rights agreement ("SAR") providing for a cash
payment to him of an amount determined by the increase in the market price of
the Bank's common stock in each of the years ended December 31, 1995, 1996 and
1997. Mr. Davis' entitlement to the payment was conditioned upon his continuing
as an employee and President through year end 1997. Under the SAR, he was
entitled to a payment of $777,594 upon the expiration of the SAR as of December
31, 1997, reflecting the significant increase in market value of the Bank's
common stock over the preceding three years, which payment was made in February
1998. The amounts included in 1996 and 1997 as other compensation reflect that
portion of the SAR expiring in each of those years, as well as the Bank's
contribution to the 401(k) Profit Sharing Plan for Mr. Davis' benefit.

(4) Consists of the Bank's contribution to employees' 401(k) Plan for the

Executive Compensation Plans and Agreements

        Employment and Change of Control Agreements. We have entered into
special agreements with certain executive officers. These agreements are
intended to motivate the executives to remain employed by us. We have entered
into an agreement expiring in July, 2002 with Raymond P. Davis that provides for
his employment as President and Chief Executive Officer and further provides for
a payment of an amount equal to nine months' base salary, plus any pro-rated
executive incentive bonus if we terminate his employment for any reason other
than "cause." In addition, we agreed to provide medical benefits to Mr. Davis
for the maximum time allowed by law. Should Mr. Davis' employment terminate as a
result of a change in control, the agreement provides for payment of an amount
equal to two times the average of the total annual compensation (including
incentive bonuses) paid to Mr. Davis during the last two full calendar years of
employment.

STOCK OPTION PLAN

        Umpqua's non-qualified stock option plan, approved by shareholders in
1995, reserves an aggregate of 1,150,000 shares of common stock for grants to
key employees. The Board of Directors designates those key employees who are
eligible. The maximum number of shares which may be issued at any given time is
limited to 10% of the shares outstanding at the time the options are granted,
excluding shares issued pursuant to the plan. Options granted under the plan may
have a term not exceeding 11 years from the date of grant and the exercise price
of the options will not be less than the fair market value of the common stock
on the date of grant.

        The purpose of the plan is to provide additional incentive to key
employees to enhance shareholder value by giving them an opportunity to
participate in the increase of such value and gain an ownership interest.
Vesting of such options occurs annually based on our financial performance for
each fiscal year measured by the return on equity and return on gross book
value. If such performance standards are not met, the options vest on the sixth
anniversary of the date of grant.

        During 1999, options for 150,000 shares of common stock were issued to
employees under the 1995 Stock Option Plan. The following table set forth grants
to the named executive officers.

(1)     The potential realizable value of the options granted is calculated by
        multiplying the difference between the exercise price of the option and
        the market value per share of the underlying stock (assuming a 5% or
        10%, as the case may be, compounded annual increase of the stock price
        from the date of grant to the final expiration of the option) by the
        number of shares underlying the options granted.

(1)     All share amounts have been adjusted to reflect subsequent stock
        dividends and stock splits through September 30, 2000.

(2)     On December 31, 1999, the market price of Umpqua common stock was $9.25
        per share. For purposes of the foregoing table, all stock options issued
        before 1998 have an exercise price less than that amount and are
        therefore considered to be "in-the-money" and have a value equal to the
        difference between $9.25 and the exercise price of the stock option,
        multiplied by the name of shares covered by the stock option. All stock
        options issued in 1998 and 1999 were issued with exercise prices
        exceeding $9.25 and are therefore not "in-the-money" at fiscal year-end.

TRANSACTIONS WITH DIRECTORS AND OFFICERS

        Some of the directors and officers and members of their immediate
families and firms and corporations with which they are associated have been
parties to transactions with South Umpqua Bank, including borrowings and
investments in time deposits. All such loans and investments in time deposits
have been made in the ordinary course of business, have been made on
substantially the same terms, including interest rates paid or charged and
collateral required, as those prevailing at the time for comparable transactions
with unaffiliated persons, and did not involve more than the normal risk of
collectibility or present other unfavorable features. As of December 31, 1999,
the aggregate outstanding amount of all loans to executive officers, directors,
principal shareholders and their associated and affiliated companies was
approximately $3,654,000 which represented 9.95% of the consolidated
shareholders' equity at that date. All such loans are currently in good standing
and are being paid in accordance with their terms.

COMPLIANCE WITH SECTION 16 FILING REQUIREMENTS

        At the time of the public offering in April, 1998, South Umpqua Bank
became subject to the reporting requirements of the Securities Exchange Act of
1934 (the "Exchange Act"). As a state-chartered bank, South Umpqua Bank filed
its periodic reports, proxy materials, and other information with the FDIC. Upon
completion of the holding company formation in March 1999, Umpqua Holdings
Corporation succeeded to the Exchange Act reporting obligations of South Umpqua
Bank, and now files its periodic reports, proxy materials, and other information
with the Securities and Exchange Commission.

        Section 16 of the Exchange Act requires that all executive officers,
directors and persons who beneficially own more than 10 percent of the common
stock file an initial report of their



                                       68
<PAGE>   75

beneficial ownership of common stock and to periodically report changes in their
ownership. The reports must now be made with the SEC.

        Based solely upon a review of the copies of the Section 16 filings with
respect to the fiscal year ended December 31, 1999, other than as stated below,
all reporting persons made all required Section 16 filings with respect to such
fiscal year on a timely basis. The Annual Statement of Changes in Beneficial
Ownership filing for Raymond P. Davis, Steven A. May, Daniel A. Sullivan, Gary
L. Pierpoint, Rodger L. Terrall, and Dolly C. Lusty were filed three days beyond
the filing deadline in order to accurately report the Company's contribution to

REPORT OF THE BUDGET AND COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

        The Budget and Compensation Committee is responsible for establishing
and administering our executive compensation program.

        Compensation Philosophy and Objectives The philosophy underlying the
development and administration of our compensation plan is the alignment of the
interests of executive management with those of the shareholders. Key elements
of this philosophy are:

        -       Set base compensation at a level to attract and retain competent
                executives.

        -       Establish incentive compensation plans which deliver bonuses
                based on the financial performance of the company.

        -       Provide significant equity based incentives for executives to
                ensure they are motivated over the long term to respond to the
                company's business challenges and opportunities, as owners
                rather than just employees.

        Incentive Plan for Senior Management. Our Incentive Plan provides for a
performance incentive payable to the President/CEO at least annually. Payment is
targeted to be 30% of the President/CEO's year-end rate of base pay for the year
in question if we meet or exceed our projected financial goals for the preceding
year. The amount of bonuses (which can exceed the target) is solely at the
discretion of the Board of Directors. Distribution normally occurs during the
first quarter of the following year.

        The plan for other key executives is payable at least annually, and is
targeted at 20% of the Executive's base pay for the year. Payment of such
performance bonus is contingent upon both our performance and the executive's
personal performance during the year. Distribution normally occurs during the
first quarter of the following year.

        The 1995 Stock Option Plan is the vehicle by which executives can earn
additional compensation depending on our financial performance. Grants are made
at the discretion of the Board of Directors and awarded to individual
executives, thereby providing additional incentive for executives to increase
shareholder value. Executives receive value from these options when our stock
appreciates over the long term.

                             STOCK PERFORMANCE GRAPH

        The chart, shown below, compares the yearly percentage change in the
cumulative shareholder return on Umpqua Holdings Corporation's common stock
during the ten fiscal years ended December 31, 1999, with (i) the Total Return
Index for The Nasdaq Stock Market (U.S. Companies) as reported by the Center for
Research in Securities Prices, and (ii) the Total Return Index for Nasdaq Bank
Stocks as reported by the Center for Research in Securities Prices. This
comparison assumes $100.00 was invested on December 31, 1989, in Umpqua Holdings
Corporation's common stock, and the comparison indices, and assumes the
reinvestment of all cash dividends prior to any tax effect, and retention of all
stock dividends. Prior to April 1998, Umpqua Holdings Corporation common stock
was not quoted on Nasdaq. Prior to its listing on Nasdaq trading activity was
limited. For purposes of computing return information for the periods being
compared, the chart is based on price information for trades that were reported
to Umpqua Holdings Corporation prior to April 1998. Price information from April
1998 to December 31, 1999, was obtained by using the Nasdaq quote as of that
date.

NET INTEREST INCOME FOR THE SIX MONTHS ENDED JUNE 30, 2000 AND THE YEARS ENDED
DECEMBER 31, 1999, 1998 AND 1997

        The primary component of earnings for financial institutions is net
interest income. Net interest income is the difference between interest income,
primarily from loans and investments, and interest expense on deposits and
borrowings. Changes in net interest income result from changes in "volume,"
changes in "spread," and changes in "margin." Volume refers to the level of
average interest-earning assets and average interest-bearing liabilities. Spread
refers to the difference between the yield on interest-earning assets and the
cost of interest-bearing liabilities. Margin refers to the ratio of net interest
income to interest-earning assets and is influenced by the mix of
interest-earning assets and interest-bearing liabilities as well as the relative
proportion of interest-bearing liabilities to interest-earning assets.

        Net interest income on a taxable equivalent basis for the six months
ended June 30, 2000 improved $1,389 over the same period in 1999 to $9,252. The
improvement was due almost entirely to increases in the volume of earning
assets. Average earning assets increased $53.8 million in 2000 compared with
1999. Average loans, the largest component of average interest earning assets
increased $61.9 million for the six month ended June 30, 2000 compared with the
same period in 1999. The yield on earning assets improved 0.43% and the cost of
interest bearing deposits also increased 0.43% while the net interest margin
decreased slightly for the six months ended June 30, 2000 to 5.36% from 5.39%
for the same period in 1999.

        Net interest income on a taxable equivalent basis was $16.6 million for
1999, a $2.9 million or 20.7% improvement over 1998. The primary reason for this
increase was an increase in the volume of earning assets, which averaged $308.7
million during 1999 compared with $256.3 million during 1998. The primary
reasons for the increase in average interest-earning assets were increases in
loans and non-taxable investment securities. Average loans were $46.4 million
higher in 1999 when compared with 1998 and average non-taxable securities
increased $10.9 million

                                       76
<PAGE>   83

during the same period. The increase in average loans was due primarily to an
increase in commercial real estate loans (see additional discussion under
Loans). The increase in average non-taxable investments was due to the
comparative attractiveness of yields available on municipal securities versus
taxable securities in 1999. The yield on average loans during 1999 declined
0.40% compared with 1998 to 9.01%. This decline was due primarily to loan
repricings in the company's variable-rate loan portfolio and was consistent with
overall rate movements during the period. The average prime rate in 1999 was
7.99% compared with 8.36% in 1998. Although the yield on loans declined 0.40%,
the yield on average interest-earning assets declined by only 0.10% due to
improvements in the mix of interest-earning assets. Average loans comprised
68.8% of earning assets during 1999 compared with 64.8% during 1998. The
increase in interest-earning assets was funded by a combination of
interest-bearing deposits, term debt, and non-interest-bearing liabilities and
equity. Average interest-bearing deposits increased $29.1 million, and average
term debt increased $12.0 million. The average cost of interest-bearing
liabilities declined 0.14% compared with 1998 to 3.50% during 1999. This decline
was consistent with overall market rates during the period.

        Comparing 1998 with 1997, net interest income increased $2.6 million,
and the margin improved 0.13% to 5.37%. The increase in net interest income was
primarily attributable to increases in average earning assets, which were up
$43.3 million. The improvement in the margin was primarily attributable to
higher non-interest-bearing liabilities and equity as a proportion of earning
assets. Average non-interest-bearing funding was 30.6% of average earning assets
in 1998 compared with 27.3% in 1997.

PROVISION FOR LOAN LOSSES FOR THE SIX MONTHS ENDED JUNE 30, 2000 AND THE YEARS
ENDED DECEMBER 31, 1999, 1998 AND 1997

        The provision expense is management's estimate of the amount necessary
to maintain an allowance for loan losses at a level which is considered adequate
based on the risk of losses inherent in the loan portfolio (see additional
discussion under Allowance for Loan Losses). The provision for loan losses for
the six months ended June 30, 2000 was $1,035 compared with $655 during the same
period in 1999. Net charge-offs were $734 for the six months ended June 30, 2000
compared with net charge-offs of $376 for the same period in 1999. Nonperforming
assets increased from $1,604 at December 31, 1999 to $1,718 at June 30, 2000.
The allowance for loan losses totaled $3,770, or 1.44% of total loans, at June
30, 2000 compared with $3,469, or 1.40% of total loans at December 31, 1999.

        Management believes the allowance has been maintained at an adequate
level with the provision for loan loss expense of $1,392,000 in 1999, $1,025,000
in 1998 and $562,000 in 1997. Loan charge-offs, net of loan recoveries, were
$587,000, $502,000 and $412,000 for the years 1999, 1998 and 1997, respectively.

NON-INTEREST INCOME FOR THE SIX MONTHS ENDED JUNE 30, 2000 AND THE YEARS ENDED
DECEMBER 31, 1999, 1998 AND 1997

        Noninterest income was $4,703 for the six months ended June 30, 2000
compared with $1,936 for the same period in 1999. The increase is primarily
attributable to $2,724 of noninterest income generated by the Umpqua's retail
brokerage subsidiary Strand, Atkinson, Williams and York. Service charges on
deposit also increased $195 for the six-month period ending June 30, 2000
compared with the same period in 1999. This increase was due to increases in the
number of



                                       77
<PAGE>   84

accounts as well as selected service fee repricing that occurred at the end of
the second quarter 1999.

        Non-interest income was $4,424,000 and $3,371,000 for the years ended
1999 and 1998, respectively. Service fees, the largest component of non-interest
income, increased $759,000 over 1998 to $2,973,000 in 1999. This 34.2% increase
was due primarily to service charges on checking accounts which were up
$435,000, and ATM fee income which was up $317,000. The increase in service
charges was due to deposit fee repricing and an increase in the number of
checking accounts. ATM fees increased due to expansion of the Umpqua's ATM
network. Other income was $370,000 in 1999 compared with $284,000 in 1998, an
$86,000 increase. Brokerage commissions and fees increased to $830,000 in 1999
compared with $523,000 in 1998. The primary reason for the increase was revenue
generated by the Umpqua's brokerage subsidiary, Strand, Atkinson, Williams &
York, Inc, which was acquired in November 1999. Gain on sale of loans declined
to $251,000 in 1999 from $349,000 in 1998. Gains on sales of loans result
primarily from the origination and sale of single family residential loans.
Loans sold were approximately $16.1 million in 1999 and $29.3 million in 1998.

        Comparing 1998 to 1997, total non-interest income increased $315,000 to
$3,371,000. Improvements in service fees, commissions and gain on sale of loans
were partially offset by a decline in the gain on sale of mortgage servicing
rights. Service fees were up due to growth in deposit accounts and expansion of
the Umpqua's ATM network. The bank sold its mortgage servicing rights in March
1997 resulting in a $583,000 gain. As a result, there was no loan servicing
income in 1999 or 1998.

NON-INTEREST EXPENSE FOR THE SIX MONTHS ENDED JUNE 30, 2000 AND THE YEARS ENDED
DECEMBER 31, 1999, 1998 AND 1997

        Non-interest expense consists principally of employees' salaries and
benefits, occupancy costs, communications expenses, marketing, professional fees
and other non-interest expenses. For the six months ended June 30, 2000
noninterest expense was $8,509 compared with $5,250 for the same period in 1999.
The primary reason for the increase was due to expenses incurred by Strand,
Atkinson, Williams & York. Details of noninterest expense by business segment is
detailed below:

</TABLE>

        The primary reason for the increase in salaries and employee benefits in
the community banking segment was staff associated with the opening of the
Portland store in July 1999 and the Salem store in January 2000 as well as
additional lending staff. Premises and equipment expense also increased as a
result of the two new stores.

        One measure of a Company's ability to contain non-interest expense is
the efficiency ratio. It is calculated by dividing total non-interest expense by
the sum of net interest income on a tax-equivalent basis and non-interest
income. Umpqua's efficiency ratio for 1999 was 55.6% compared with 55.3% in 1998
and 61.9% in 1997. The increase in 1999 was due partially to the operating
expenses of Strand, Atkinson, Williams & York, Inc. The operating costs for the
retail brokerage business are higher than those for the bank. Excluding the
income and operating costs of Strand, Atkinson, Williams & York, Inc., the
efficiency ratio for 1999 would have been 55.2%.

        Non-interest expense for 1999 increased $2,224,000 over 1998 to
$11,702,000. Salaries and benefits increased $1,115,000. Salaries and benefits
expenses at Strand, Atkinson, Williams & York, Inc. accounted for $259,000 of
the increase while the remainder was due to expansion at the Bank. Full-time
equivalent employees at the bank grew from 157 at the end of 1998 to 175 at the
end of 1999. Occupancy expense increased $240,000 over 1998 to $945,000 for
1999. This increase was due to the opening of a new Portland store, a new loan
center, the relocation and expansion of the Sutherlin store, and the opening of
a Support and Accounting Office. Marketing expense increased $206,000 over 1998
to $942,000 in 1999 as the result of increased marketing efforts and the
expansion into new markets. Communications expenses, which consist primarily of
postage and telephone expense, were $786,000 in 1999 compared with $630,000 in
1998. The increase was due to the bank's increased loan and deposit base, as
well as expansion of the bank's ATM network and costs associated with new and
remodeled facilities. Professional services include director fees, attorney
fees, accountant fees, security services and other fees. Professional fees were
up $322,000 in 1999 compared with 1998 due primarily to the expansion and
servicing of the bank's ATM network and increased internal audit and accounting
fees.

        Comparing 1998 with 1997, total non-interest expense increased $678,000
to $9,478,000. Communications expense in 1998 increased $127,000 compared with
1997 due to the bank's increased loan and deposit base, as well as costs
associated with the ATM network. Professional fees were $1,021,000 in 1998
compared with $796,000 in 1997. The increase from 1997 was due to increased
security services related to store and ATM network expansion, and additional
expenses as the result of becoming a publicly traded company in 1998.

INCOME TAXES FOR THE SIX MONTHS ENDED JUNE 30, 2000 AND THE YEARS ENDED DECEMBER
31, 1999, 1998 AND 1997

        The effective tax rate for Umpuqa was 36.0% during the second quarter of
2000 compared with 35.7% during the second quarter of 1999. For the six months
ended June 30, 2000 the company's effective tax rate was 35.6% compared with
36.1% for the same period in 1999.

        The provision for income taxes was $2,681,000, $2,382,000 and $1,699,000
for the years 1999, 1998 and 1997, respectively. The provision resulted in
effective combined federal and state tax rates of 35.5%, 36.7% and 35.8%. The
1.2% decrease in the effective rate from 1998 to 1999 was due to increased
non-taxable revenue generated by the company. In 1997 Umpqua's state income tax
rate was reduced from 6.6% to 3.8% due to surplus revenues received by the State
of Oregon.

INVESTMENT PORTFOLIO

        Investment securities have not materially changed since between December
31, 1999 and June 30, 2000. Investment securities held at December 31, 1999 were
$76,869,000 compared with $84,888,000 at December 31, 1998. The objectives of
the investment portfolio are to provide liquidity, offset interest rate risk
positions and provide a profitable interest yield to the company. Umpqua
classifies all of its investment securities as "available-for-sale" and
consequently carries them at fair value. At December 31, 1999 the company had
net unrealized losses of $2,872,000 compared with net unrealized gains at
December 31, 1998 of $1,023,000. Unrealized gains/ losses reflect changes in
market conditions and do not represent the amount of actual profits or losses
the company may ultimately realize. Actual gains and losses are recognized at
the time investment securities are sold or redeemed. The net unrealized losses
resulted from the effect that increasing market interest rates had on the
company's fixed-rate investment portfolio. The following tables provide details
of the company's investment portfolio and its maturity distribution and yields.

        The following table provides the carrying values of the company's
portfolio of investment securities as of December 31, 1999 and 1998:

Outstanding loans, excluding mortgage loans held for sale, were $248.5 million
at December 31, 1999 compared with $186.2 million at December 31, 1998. Real
estate mortgage loans increased $34.4 million from year-end 1998 to year-end
1999 while construction loans increased $16.2 million during the same period.
The bank also experienced strong growth in the Commercial and Industrial loan
segment, which was up $12.0 million between December 31, 1998 and December 31,
1999. The bank's loan portfolio carries credit risk, which could result in loan
charge-offs. The company manages this risk through the use of credit policies
and review procedures. (See additional information under the Allowance for Loan
Losses discussion.)

NON-PERFORMING LOANS

        Commercial and real estate loans are placed on non-accrual status when
they are 90 days past due as to principal or interest, unless the loans are both
well-secured and in the process of collection. Non-performing assets have not
materially changed between December 31, 1999 and June 30, 2000. The increase in
non-accrual loans between 1999 and 1998 was primarily due to the addition of one
large commercial loan in late 1999.

The following table presents information with respect to non-performing assets:

ALLOWANCE FOR LOAN LOSSES. The allowance for loan losses is maintained at a
level considered by management to be adequate to absorb losses inherent in the
loan portfolio. Management monitors and evaluates the adequacy of the allowance
on an ongoing basis. The following tools are used to manage and evaluate the
loan portfolio:

        -       Internal credit review and risk grading system

        -       Regulatory examination results

        -       Monitoring of charge-off, past due and non-performing activity
                and trends

        -       Assessment of economic and business conditions in our market
                areas


                                       83
<PAGE>   90

        On a quarterly basis, losses inherent in the portfolio are estimated by
reviewing the following key elements of the loan portfolio:

        -       Portfolio performance measures

        -       Portfolio mix

        -       Portfolio growth rates

        -       Historical loss rates

        -       Portfolio concentrations

        -       Current economic conditions in our market areas

    Umpqua also tests the adequacy of the allowance for loan losses using the
following methodologies:

        -       Loss allocation by internally assigned risk rating

        -       Loss allocation by portfolio type, based on historic loan loss
                experience

        -       The allowance as a percentage of total loans

        The allowance for loan losses is based upon estimates of losses inherent
in the portfolio. The amount of losses actually incurred can vary significantly
from these estimates. Assessing the adequacy of the allowance on a quarterly
basis allows management to adjust these estimates based upon the most recent
information available.

        At December 31, 1999 the allowance for loan losses was $3,469,000, or
1.4% of total loans, and is considered by management adequate to absorb credit

CAPITAL EXPENDITURES

        Capital expenditures for premises and equipment were $2.9 million, $0.5
million and $2.1 million for the years ended December 31, 1999, 1998 and 1997,
respectively. Capital expenditures in 1999 included a Support and Accounting
Office, a new Sutherlin store, a new Portland store, additional ATMs, a remodel
of the company's executive offices, and the construction of a store in Salem,
which opened in January 2000.

DEPOSITS AND BORROWINGS

        Total deposits increased to $344,601 at June 30, 2000, a $42.9 million
increase over December 31, 1999. The increase consisted primarily of a $30.5
million increase in time deposits and a $9.4 million increase in noninterest
bearing deposits. Deposits at the company's Salem store which opened in January
2000 were $17.7 million at June 30, 2000.



                                       85
<PAGE>   92

        Total deposits increased $45.9 million over year-end 1998 to $301.7
million at December 31, 1999. Deposits in Lane County increased $26.8 million as
the bank continued to expand its penetration into that market. Deposits in
Douglas County also increased $15.2 million during 1999. Umpqua does not depend
on brokered deposits or higher than market priced time deposits. At December 31,
1999 time certificates of deposit of $100,000 or more were $28.9 million
compared with $24.0 million at December 31, 1998.

        Borrowings increased $21.0 million during 1999 due to strong loan demand
and the building up of liquidity in anticipation of possible Year 2000 depositor
withdrawals. Approximately $6 million of the increase in borrowings was due to
the liquidity build-up. The $6 million of borrowings were repaid in January
2000.

interest-bearing liabilities, interest expense and average rates paid for the

ASSET-LIABILITY MANAGEMENT/INTEREST RATE SENSITIVITY

        Asset and liability management is an integral part of managing a
financial institution's primary source of income, net interest income. Umpqua
manages the balance between the rate-sensitive assets and rate-sensitive
liabilities being repriced in any given period with the objectives of minimizing
fluctuations in net interest income. The company considers its rate-sensitive
assets to be those that either contain a provision to adjust the interest rate
periodically or mature within one year. These assets include certain loans and
investment securities and interest-bearing deposits in other banks.
Rate-sensitive liabilities are those liabilities that are considered sensitive
to periodic interest rate changes within one year, including maturing time
certificates, certain savings deposits and interest-bearing demand deposits. The
difference between the aggregate amount of assets and liabilities that reprice
within various time frames is called the "gap." Generally, if repricing assets
exceed repricing liabilities during a time frame, the company would be deemed to
be asset sensitive. If aggregate repricing liabilities exceeded aggregate
repricing assets during a time frame, the company would be deemed to be
liability sensitive during that time frame. The company generally seeks to
maintain a balanced position within one year, whereby the difference between
assets and liabilities repricing is minimized. This is accomplished by
maintaining a significant level of loans, investment securities and deposits
available for repricing within one year.

        According to the traditional financial institution industry static gap
basis table set forth on the following page, the company was slightly liability
sensitive within one year. Changes in interest rates would not be expected to
have a significant impact on net interest margin.



                                       86
<PAGE>   93

        In addition to this static gap report, management performs a financial
analysis (dynamic gap) to specifically analyze the change in net interest margin
from a changing rate environment. The estimate of interest rate sensitivity
takes into account the differing time intervals and differing rate change
increments of each type of interest sensitive asset and liability. It then
measures the projected impact of changes in market interest rates on the
company's net interest income, net interest margin, and return on equity.

        The interest rate gaps in the following table arise when assets are
funded with liabilities having different repricing intervals. Since these gaps
are actively managed and change daily as adjustments are made in interest rate
views and market outlook, positions at the end of any period may not be
reflective of the company's interest rate sensitivity in subsequent periods.
Active management dictates that longer-term economic views are balanced against
prospects for short-term interest rate changes in all repricing intervals. For
purposes of the analysis above, repricing of fixed-rate instruments is based
upon the contractual maturity of the applicable instruments. Actual payment
patterns may differ from contractual payment patterns. The change in net
interest income may not always follow the general expectations of an asset
sensitive or liability sensitive balance sheet during periods of changing
interest rates, because interest rates earned or paid may change by differing
increments and at different time intervals for each type of interest sensitive
asset or liability. As a result of these factors, at any given time, the company
may be more sensitive or less sensitive to changes in interest rates than
indicated in the following table.

LIQUIDITY

        Liquidity enables the bank to meet the borrowing needs of its customers
and withdrawals of its depositors. Umpqua meets its liquidity needs of the bank
through the maintenance of cash resources, lines of credit with other financial
institutions, and a stable base of core deposits. Excess funds, when available,
are deposited on a short-term basis with the Federal Home Loan Bank (FHLB),
whose interest rates approximate Federal Funds sold. The bank's main source of
funds is the deposits of its individual and commercial customers. Having a
stable and diversified deposit base is a significant factor in the company's
long-term liquidity structure.

        Umpqua's liquidity position has not materially changed between December
31, 1999 and June 30, 2000.



                                       88
<PAGE>   95

        At December 31, 1999 the bank had a total funding line with the FHLB of
$88.2 million. The outstanding balance of term advances was $46.2 million at
December 31, 1999 leaving an available balance of $42.0 million. The bank also
had available lines of $18.4 million from financial institutions. At December
31, 1999 the bank had $15.6 million in interest-bearing deposits with the FHLB.
The company also has the flexibility of selling securities from its
available-for-sale portfolio to meet liquidity needs.

CAPITAL

        Management seeks to maintain capital at a level that provides
shareholders, customers and regulators with assurance of the company's financial
soundness, while at the same time employing leverage to achieve a desirable
level of profitability.

        On February 8, 1999 the Board of Directors authorize the repurchase of
up to 500,000 shares of the company's common stock. The company repurchased
89,625 shares during 1999.

        The bank is subject to certain minimum regulatory capital standards.
These minimum standards include maintaining Tier 1 Capital at 4.0% and Total
Capital at 8.0% of risk-weighted assets. At December 31, 1999 the bank had a
Tier 1 ratio of 13.81% and a Total Capital ratio of 15.06%

INFLATION

        Assets and liabilities of a financial institution are primarily monetary
in nature. Therefore, inflation has a less significant impact on financial
institutions than fluctuations in interest rates. Inflation, as measured by the
Consumer Price Index, has not changed significantly during the past two years
and has not had a material impact on the company.


                       INFORMATION CONCERNING VRB BANCORP

INTRODUCTION

        VRB Bancorp was organized in 1983 as the holding company for Valley of
the Rogue Bank, an Oregon state-chartered bank organized in 1967. VRB conducts
its business solely through Valley of the Rogue Bank, headquartered in Rogue
River, Oregon.

        VRB is the second largest community bank based in southern Oregon,
currently operating 13 full service branches. The bank has prospered by
providing excellent customer service to consumers and small to medium sized
businesses, and has acquired four other financial institutions since its
inception. Over the last five years, earnings have grown by 68% and the return
to shareholders has consistently exceeded 14%. Other traditional indicators of
financial strength, such as a strong loan portfolio and a robust capital
position, are indicative of the bank's success in implementing its business
plans.

        VRB emphasizes a personalized approach to banking, and targets those
customers that utilize traditional products and services. The technological
sophistication of the region is growing, and use of the bank's ATM network,
debit cards and 24 hour telephone banking is now routine for most customers. VRB
has recently committed to purchase and implement an Internet banking product
that includes the cash management functionality that is key to developing and
retaining business customers. VRB believes that investment in technology is
vital to its survival, and it has improved its own infrastructure with new voice
and data communications systems, high-speed



                                       89
<PAGE>   96

Internet connectivity, and real time virus containment. In addition, the bank
has started to build a bridge to other paperless processes including check
imaging.

PRODUCTS AND SERVICES

Commercial banking

        The commercial banking group features personalized commercial banking
services to small and mid-sized businesses and makes available real estate
construction, commercial real estate and operating lines of credit. Such loans
often include innovative or flexible programs that are specifically designed to
target certain market sectors such as the professional services and healthcare
industries. As of June 30, 2000, the bank had approximately $175 million in
commercial loans and $81 million in business deposits.

Consumer banking

        The consumer banking business includes the sale of all consumer deposit
products, including checking accounts, money market accounts and time deposits
as well as the origination of mortgage loans through VRB Mortgage, the bank's
mortgage division. The bank also offers consumer loan products that include
second equity mortgage loans, personal lines of credit, and automobile, boat,
and recreational vehicle loans. As of June 30, 2000, the bank had approximately
$198 million in consumer deposits and a consumer loan portfolio of $44 million.

MARKET AREA

        VRB primarily conducts its business in Jackson and Josephine counties in
southern Oregon. The two counties have experienced significant growth, and the
area continues to attract an influx of retirees who find the cost of living to
be substantially lower than neighboring states. VRB has expanded as the area
becomes increasingly urbanized and now garners 17.7% and 9.6% in market share
for Josephine and Jackson counties, respectively. VRB seeks to refine its branch
network, and in those areas where multiple locations are unnecessary to maintain
a competitive advantage, is inclined to close or consolidate branches that are
in close proximity.

        The bank's long-term strategies include expansion outside its current
market. VRB's management expects that such expansion would be centered along the
1-5 corridor and extending its banking services into the Willamette Valley
regions to the north.

EMPLOYEES

        As of June 30, 2000, VRB had a total of 172 full-time equivalent
employees. A number of benefit plans are available to eligible employees,
including paid sick leave and vacation, group medical plans, a 401(k) plan, and
a discretionary stock option plan. None of VRB's employees are subject to a
collective bargaining agreement and the company considers its relationships with
its employees to be good.

TRANSACTIONS WITH MANAGEMENT

        Various Directors and executive officers are customers of and have had
banking transactions with Valley of the Rogue Bank, in the ordinary course of
business, and the bank



                                       91

expects to have such transactions in the future. All loans and commitments to
loan included in such transactions were made in compliance with applicable laws,
on substantially the same terms (including interest rate and collateral) as
those prevailing at the time for comparable transactions with other persons and,
in the opinion of management of the bank, do not involve more than the normal
risk of collectibility or present any other unfavorable features. The amount of
loans outstanding to directors, executive officers, and companies with which
they are associated was $5,542,248 at December 31, 1999.

COMPLIANCE WITH SECTION 16 FILING REQUIREMENTS

        Section 16 of the Securities Exchange Act of 1934, as amended, requires
that all executive officers and directors, and all persons who beneficially own
more than 10 percent of VRB's common stock, file an initial report of their
ownership of VRB's securities on Form 3 and report changes on their ownership of
VRB's securities on Form 4 or Form 5. These filings must be made with the
Securities and Exchange Commission with a copy sent to VRB.

        Based solely upon our review of the copies of the filings that it
received with respect to the fiscal year ended December 31, 1999, we believe
that all reporting persons made all required Section 16 filings with respect to
such fiscal year on a timely basis.


                    VRB MANAGEMENT'S DISCUSSION AND ANALYSIS

INDUSTRY TRENDS AND COMPANY ANNOUNCEMENTS

        Branch openings and closures: On January 31, 2000, VRB opened a
temporary branch in Central Point, Oregon. Central Point continues to be one of
the fastest growing communities in southern Oregon and initial acceptance of the
temporary branch has been very positive. Branch assets and deposits have grown
to $9 million and $1.5 million, respectively as of June 30, 2000. Construction
on the permanent facility has commenced and the new facility is expected to be
open for business in the fourth quarter of 2000.

        On May 15, 2000, the bank announced the impending closure of one of its
four branches located in Medford, Oregon. The branch closure, which took place
on August 15, 2000, came as a result the company's plan to streamline its branch
network and reduce operating overhead.

        Interest Rate environment: Prior to the third quarter of 1999, VRB
operated under a relatively low interest rate environment. Subsequently,
interest rates rose rapidly as a result of a number of successive rate hikes. By
the end of the second quarter of 2000, the bank's prime lending rate had risen
to 9.25%, 1.50% higher than prime one year ago. While rate volatility has
influenced the yield on loans and interest paid on deposits, the bank's net
interest margin has remained close to the 6% mark in both 1999 and 2000
year-to-date. In addition, loan demand appears unhindered, with growth of 23%
over the last 18 months.

RESULTS OF OPERATIONS

        Net income for the six-month periods ended June 30, 2000 and 1999. Net
income for the six months ended June 30, 2000 increased 1.2% to $2,458,000
compared to the same period last year. On a per share basis, earnings increased
from $.28 in 1999 to $.30 in 2000, an increase of 7%. VRB's share repurchase
plan (in effect throughout 1999) reduced the company's average shares
outstanding by approximately 400,000 shares, which enhanced the company's
earnings on a per share basis.



                                       92
<PAGE>   99
        Net income for the years ended December 31, 1999 and 1998. Net income in
1999 totaled $4.9 million, substantially unchanged from that in 1998. Earnings
per share for each period was also consistent, averaging $0.57 per outstanding
share. Internal departmental restructuring, and pressure on interest margins
influenced earnings growth. Costs to establish a brand image, and strengthen the
lending and technological capabilities of the bank also lead to higher costs.
Management believes that these costs will be recovered in the form of future
efficiencies and profitability.

        NET INTEREST INCOME

        For financial institutions, the primary component of earnings is net
interest income, which is the difference between interest income from loans and
investment securities and interest expense on deposits. Over the last 18 months,
VRB has sustained its net interest income levels in the face of rapidly changing
interest rates and increased competitive pressures. At the close of the second
quarter, the profile of the company had changed significantly from that in 1999.
Loans growth was strong, liquidity had diminished, and deposit rates were rising
under an extremely competitive market.

        Net interest income for the six-month periods ended June 30, 2000 and
1999. Net interest income (on a tax equivalent basis) increased from $8,270,000
to $8,389,000 when comparing the six months ended June 30, 1999 and 2000. The
increase reflected the net effect of the following:

        -       Interest earned on loans grew by 9.9%, due primarily to higher
                volume.

        -       Unusually strong loan growth caused the bank to utilize its line
                of credit with the Federal Home Loan of Seattle, and 84% of
                second quarter loan growth was funded with short-term debt. For
                the period, the bank averaged $3.4 million in overnight
                borrowings, resulting in interest expense of approximately
                $111,000.

        -       Interest expense grew as the bank paid a higher average rate on
                interest bearing deposits (primarily time certificates of
                deposit). Overall, the bank's cost of funds grew from 2.33% to
                2.45%.

        Net interest income for the years ended December 31, 1999 and 1998.
During 1999, the average yield on interest earning assets declined by 0.48%,
reflecting the low interest rate environment in effect for most of 1999. The
decline is also due to the mix of earning assets, which grew to include a higher
percent of lower yielding available-for-sale securities. Offsetting the decline
in asset yields, the cost of interest bearing liabilities also declined from
3.71% to 3.18%. In addition, VRB experienced a $14.3 million decline in time
certificates of deposits, which are typically more expensive than other deposit
products. Declining time certificates of deposit were replaced by less expensive
funding, which resulted in a lower average cost of funds for the year.

        FEE INCOME

        For the six month periods ended June 30, 2000 and 1999. Fee income, or
non-interest income, increased by $228,000, or 23%, when comparing the first six
months of 1999 and 2000. In May, the bank updated its fee structure, which
resulted in the more frequent assessment of account charges for certain products
and services. Also contributing to the increase in fee income were ATM surcharge
fees beginning February 2000.

        For the years ended December 31, 1999 and 1998. Fee income, or
non-interest income, totaled $2.1 million, a 4% decline when compared to the
prior year. As a percent of total revenues, fee income equaled 8.3% of total
revenues in 1999, substantially unchanged from 1998. The decline in non-interest
income is due to the decrease in residential mortgage loans originated through
the bank's mortgage lending department.

        In the third quarter of 1999, the mortgage lending process was
restructured and moved in-house to include local processing, underwriting and
closing of residential real estate loans. In connection with the restructure,
the department introduced new products and expanded its mortgage services.
Management believes the mortgage department is now positioned to capture a much
larger share of the market; however, the origination and refinance of mortgage
loans and related fees are dependent on the general level and direction of
interest rates. Accordingly, there can be no assurance that such income will
improve in the future.

        COST OF OPERATIONS

        For the six months ended June 30, 2000 and 1999. Cost of operations, or
non-interest expense, grew to $5.4 million year-to-date. Salaries and
depreciation expense were primarily responsible for the 7% increase, reflecting
the bank's investment in both people and technology during this period.

        The bank's efficiency ratio, or non-interest expense as a percentage of
total net interest income plus non-interest income, was 56.6% for the six months
ended June 30, 2000 compared to 54.9% for the same period in 1999. Excluding the
amortization of intangibles, such as goodwill from VRB's acquisition of Colonial
Banking Company ("CBC") (an approximate charge of $640,000 per year), the
efficiency ratio improves to 52.7% and 50.9% for the periods ended June 30, 2000
and 1999, respectively.

        For the years ended December 31, 1999 and 1998. Cost of operations grew
to $10.6 million, an increase of less than one percent. VRB hired a number of
senior lending and calling officers in 1999 to generate loan growth. As a
results, salaries and benefits rose from $6.0 million to $6.3 million, a 5.6%
increase. VRB had 177 full time equivalent employees at December 31, 1999
compared to 167 full time equivalent employees at December 31, 1998.

        Occupancy costs, including depreciation, rent and small equipment,
increased by 12.9% to $1.2 million. In 1999, VRB embarked on a campaign to
upgrade operating equipment and streamline data and voice communications,
investing $1.1 million into capital projects and company infrastructure.

        With the exception of communication costs (primarily postage and phone
service), other administrative expenses declined slightly, centered around
reductions in professional fees and other one-time expenses related to the
acquisition of CBC in 1998 (see Note 2 in Notes to consolidated financial
statements).

        In 1999, VRB maintained an efficiency margin of 56.2%, slightly higher
than 1998's efficiency margin of 55.6%. Excluding the amortization of goodwill
from the measurement, the efficiency margin drops to 52.4% and 51.7% for 1999
and 1998, respectively.

        COMPARISON OF RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31,
        1998 AND 1997

        In the first quarter of 1998, VRB acquired CBC. CBC was a state charted
bank with approximately $116 million in total assets. CBC added four branches to
VRB's existing branch network in Southern Oregon. VRB paid $15.7 million in
cash, which was approximately 2.5 times book value. The acquisition of CBC
brought increased market share to the company and preempted the acquisition of
CBC by potential competitors looking to enter the Rogue Valley market.

        Earnings grew to $4.9 million in 1998, up $1.2 million or 33% when
compared to 1997. Diluted earnings per share grew to $.57, an increase of 18%
from $.48 in 1997. Earnings accretion from the CBC acquisition was partially
diluted by the sale of 1.1 million shares of VRB common stock, the proceeds of
which were used to finance the CBC acquisition.

        The acquisition of CBC altered VRB's deposit structure with a new
emphasis in high cost certificates of deposit (27% of total deposits compared
16% pre acquisition). CBC also brought an unusually large concentration of out
of area commercial loans with very low interest rates. The net portfolio return
on CBC loans was approximately 70 basis points lower than VRB's then-current
average. While net interest income grew by $1.3 million, VRB's interest margin
declined to from



                                       96

6.69% to 6.01%. Noninterest income and expenses also reflected the acquisition,
growing 28% and 52% respectively.

FINANCIAL CONDITION

        LENDING AND CREDIT MANAGEMENT

        As of June 30, 2000 and December 31, 1999, and 1998. Outstanding loans
totaled $219.4 million at June 30, 2000, representing a $17.6 million increase
when compared to loans of $201.7 million as of December 31, 1999 and a $40.3
million increase when compared to December 31, 1998. Loan growth has been
diversified across all categories, with the biggest gains in commercial real
estate and commercial lines of credit. Loan growth is the result of aggressive
calling strategies, innovative terms and favorable economic conditions.
Commitments to extend credit totaled $34 million as of June 30, 2000, relatively
unchanged when compared to commitments outstanding as of the end of the previous
two years.

The following table presents the composition of the bank's loan portfolio at the

        LOAN LOSS RESERVE

        As of June 30, 2000 and December 31, 1999, and 1998. The reserve for
loan losses represents management's estimate of the bank's exposure to credit
loss when evaluating the asset quality of the loan portfolio. The reserve is
based primarily on management's evaluation of the overall risk characteristics
of the bank's loan portfolio based on internally established guidelines, an
evaluation that is influenced by current overall levels of non-performing loans,
value of collateral securing a particular loan, general and local economic
conditions, and the bank's overall historical loan loss experience. Management
seeks to control credit losses by maintaining strong underwriting standards and
by closely monitoring each borrower's financial condition.

        VRB has established credit policies and guidelines that control and
monitor credit risk on an ongoing basis. Managing credit risk is the
responsibility of all loan officers, working under the oversight of the bank's
loan administrator. Each credit is regularly evaluated as to the likelihood that
a borrower will repay a loan from expected sources. When collateral is involved,
this includes evaluating whether sufficient collateral is obtained at the
outset, and verifying that the value of the collateral remains sufficient to
support the credit.

        INVESTMENTS

        As of June 30, 2000 and December 31, 1999, and 1998. Investment
securities are purchased to help manage liquidity and generate after-tax profits
consistent with the risk guidelines established by management and the Board of
Directors. As of June 30, 2000, the bank's portfolio of investment securities
totaled $73.2 million, virtually unchanged when compared to the December 31,
1999 and 1998 balance of $74.8 and $76.5 million, respectively.

        As of June 30, 2000, the bank's investment portfolio that is currently
available-for-sale ("AFS") totaled $54.0 million, or approximately 74% of the
total portfolio. Due to rising interest



                                       98
<PAGE>   105

rates, the market value of the bank's AFS portfolio has dropped by approximately
$2.6 million, before accruing for tax benefits. This represents a 4.5% percent
decline in the aggregate market value of the bank's AFS investments. If
long-term interest rates continue to rise, the value of the bank's investment
holdings will most likely continue to decline. This could hinder the bank's
ability to liquidate securities quickly without incurring a loss on the sale.
Because future interest rate fluctuations are subject to great uncertainty,
management continues to monitor the market value of the portfolio in relation to
current liquidity needs on a regular basis.

        The following table provides the book value of the bank's investment
portfolio as divided between HTM and AFS as of June 30, 2000 and December 31,
1999 and 1998:

        DEPOSITS

        As of June 30, 2000 and December 31, 1999, and 1998. Deposits are the
bank's principal source of funds available for lending and other investment
opportunities. Deposit inflows and outflows are influenced by general interest
rate changes, competition and local, regional and national economic conditions.
Substantially all of the bank's depositors are individuals or businesses located
in southern Oregon.

        Total deposits increased $2.7 million, or 1%, when comparing June 30,
2000 to the end of the prior fiscal year. Non-interest bearing deposits have
increased to 29.3% of total deposits, up from 27.1% at year-end. High
concentrations in non-interest bearing accounts provide inexpensive funding
evidenced by the fact that the bank's cost of funds has averaged 2.50% for the
year, to date. However, non-interest bearing account balances are also prone to
volatility and can fluctuate from day to day depending on the time of month and
external events like tax deadlines.

The bank's current deposit mix is further illustrated below:

        LIQUIDITY

        As of June 30, 2000. Liquidity enables VRB to meet the borrowing needs
of its customers and deposit withdrawals of its depositors. VRB manages its
liquidity through a mature and stable base of customer deposits, various lines
of credit with other financial institutions and cash flows from continuing
operations.

        VRB maintains a cash management credit facility with the Federal Home
Loan Bank. The credit facility is limited to 10% of the holding company's total
assets (approximately $30 million at December 31, 1999) measured on a quarterly
basis. The credit facility is collateralized by FHLB stock owned by VRB and by
all VRB's other assets. In addition, VRB maintains federal funds lines with
correspondent banks as an alternative source of temporary liquidity. At June 30,
2000, VRB had available federal funds lines totaling $8 million.

        Overall liquidity declined in 2000 as loan balances grew while deposits
remained relatively unchanged. As a result, the bank drew from its line of
credit with the Federal Home Loan Bank ("FHLB") intermittently during the
period. At the end of the second quarter, the bank had $11 million in overnight
borrowings. Management expects that the bank will continue to borrow from the
FHLB and that the volume of such borrowings will depend on deposit growth and on
the bank's ability to continue to grow its loan portfolio.

        For the first six months of 2000, the bank experienced net cash outflows
(cash and federal funds) of approximately $1,000,000. The net impact of cash
inflows and outflows included net loan growth of $17.5 million, funded by a
combination of $11.0 million in debt (reflected in an increase in the FHLB line
of credit), new deposits of $2.7 million and $2.9 million in cash from ongoing
operations.

        CAPITAL RESOURCES

        As of June 30, 2000. As of June 30, 2000, shareholders' equity totaled
$34.9 million, an increase of $1.3 million when compared to total shareholders'
equity as of the end of the last fiscal year. The increase in shareholders'
equity reflects earnings of $2.5 million offset by dividends of $1.0 million
($0.12 per share) paid May 1, 2000.

        The bank is required to maintain minimum amounts of capital to
"risk-weighted" assets, as defined by banking regulators. At June 30, 2000, the
bank was required to have Tier 1 and Total Capital ratios of 4.0% and 8.0%,
respectively. The bank's actual ratios at that date were 10.9% and 12.1%,
respectively.

        MARKET RISK

        In the normal course of business, interest rate and credit risks are the
most significant market risks that could have an adverse impact on the bank's
financial condition and results of operations. Other types of market risk, such
as foreign currency exchange rate risk and commodity price risk, do not have a
material effect on the bank's operations at this time.

        Interest rate risk. Interest rate risk is the risk that changes in
market interest rates will have an adverse impact on VRB's earnings. The
greatest source of interest rate risk results from the mismatch of maturities
and repricing intervals for rate sensitive assets, liabilities and off balance
sheet commitments. To further illustrate, if VRB makes long term fixed rate
loans and finances them with floating-rate deposits, a gap mismatch is created
because the repricing period for loans and deposits are different. If interest
rates were to rise in this scenario, VRB may be obligated to pay more interest
on deposits while receiving the same amount of interest on loans.

        VRB measures its interest rate risk using asset/liability simulation
modeling which quantifies variations in net interest income due to changes in
the rate environment. The analysis incorporates maturity and repricing
characteristics of VRB's current configuration of interest bearing assets and
liabilities. By adjusting interest rates up or down in even increments of 100
and 200 basis points in a series of "rate shocks," VRB can develop a range of
possible outcomes.

        As of June 30, 2000, the table below sets forth the estimated changes in
VRB's unaudited net interest income over a period of one year under the
scenarios set forth.

</TABLE>

        Certain shortcomings are inherent in the above analysis. Management has
made relatively broad assumptions regarding customer behavior in periods of
changing interest rates, including the prepayment characteristics of loans and
the repricing and withdrawal of deposits. Additionally, certain assets, such as
adjustable rate loans have features, which restrict changes in interest rates.
The interest rate sensitivity of VRB's net interest income could vary
significantly if different assumptions were used, or if actual experience
differs from the assumptions used.


                                   COMPETITION

        The community banking business is highly competitive. The companies
compete with other commercial banks and with other financial institutions,
including savings and loan associations, mutual savings banks, finance
companies, mortgage banking companies, credit unions, and investment companies.
In recent years, competition has increased from institutions not subject to the
same regulatory restrictions as banks and bank holding companies.



                                      101
<PAGE>   108

        The geographic market areas served by both South Umpqua and Valley of
the Rogue Bank are highly competitive for both deposits and loans. Each competes
with traditional banking and thrift institutions, as well as non-bank financial
services providers, such as credit unions, brokerage firms and mortgage
companies. The major commercial bank competitors are super-regional institutions
headquartered outside the state of Oregon, and their deposits represent a
significant majority of total statewide commercial bank deposits. The major
banks have competitive advantages over the banks in that they have higher
lending limits and are able to offer statewide facilities and services that
neither of the banks currently offer.

        The banks, however, view non-bank financial services providers, such as
credit unions, brokerage firms, insurance companies and mortgage companies, as
its principal competition. As the industry becomes increasingly dependent on and
oriented toward technology-driven delivery systems permitting transactions to be
conducted by telephone, computer and the internet, such non-bank institutions
are able to attract funds and provide lending and other financial services even
without offices located in the bank's primary service area. Some insurance
companies and brokerage firms compete for deposits by offering rates that are
higher than may be appropriate for a bank in relation to its asset/liability
objectives, although the banks offers a wide array of deposit products and
believes they can compete effectively through select rate-driven product
promotions.

        Credit unions present a significant competitive challenge. As credit
unions currently enjoy an exemption from corporate income taxes, they are able
to offer higher deposit rates and lower loan rates than the banks. Credit unions
are also not currently subject to certain regulatory constraints applicable to
the banks such as the Community Reinvestment Act, which, among other things,
requires regulated financial institutions to implement procedures to make and
monitor loans throughout the communities it serves. Adhering to such regulatory
requirements raises the costs associated with the bank's lending activities, and
reduces potential operating profits. Accordingly, the banks seek to compete by
focusing on building customer relations, providing superior service and offering
a wide variety of commercial banking products such as commercial real estate
loans, inventory and accounts receivable financing, and SBA loans for qualified
businesses, that do not compete directly with products and services offered by
the credit unions.

        The acquisition by Umpqua of Strand, Atkinson, Williams & York, Inc., a
retail brokerage firm, further permits Umpqua to offer a full range of brokerage
services and investment insurance products to its banking customers as well as
to other customers of the firm. Management of Umpqua believes that providing
these additional financial services through its banking stores will help
differentiate it from many other banks and provide additional revenue for the
company.

                        CERTAIN REGULATORY CONSIDERATIONS

        Umpqua is a registered Financial Holding Company under the
Gramm-Leach-Bliley Act of 1999 (the "Act"), and is subject to the supervision
of, and regulation by, the Board of Governors of the Federal Reserve System (the
"Federal Reserve"). To continue its status as a financial holding company,
Umpqua must maintain its "well capitalized" and "well managed" status.
Additionally, its subsidiary must also receive "satisfactory or better" ratings
on the last CRA exam. The Federal Reserve reserves authority to limit the
activities of a financial holding company if it finds the company as a whole
lacks the financial or managerial strength to engage in new activities, make new
acquisitions or retain ownership of companies engaged in financial activities.



                                      102
<PAGE>   109

        VRB is a registered bank holding company and is also subject to the
supervision of, and regulation by, the Federal Reserve.

        General - Both subsidiary banks and Umpqua's broker-dealer subsidiary
are extensively regulated under federal and state law. These laws and
regulations are generally intended to protect depositors, borrowers and other
customers, not shareholders. To the extent that the following information
describes statutory or regulatory provisions, it is qualified in its entirety by
reference to the particular statutory or regulatory provisions. Any change in
applicable laws or regulations may have a material effect on the business and
prospects of the companies. Neither company can accurately predict the nature or
the extent of the effects on its business and earnings that fiscal or monetary
policies, or new federal or state legislation may have in the future.

        Federal and State Bank Regulation - The banks, as state chartered banks
with deposits insured by the Federal Deposit Insurance Corporation, are also
subject to supervision and regulation by the Oregon Director of the Department
of Consumer and Business Services and the FDIC. These agencies may prohibit the
banks from engaging in what the agencies believe constitute unsafe or unsound
banking practices.

        The Community Reinvestment Act ("CRA") requires that, in connection with
examinations of financial institutions within its jurisdiction, the FDIC
evaluate the record of the financial institutions in meeting the credit needs of
their local communities, including low and moderate income neighborhoods,
consistent with the safe and sound operation of those institutions. These
factors are also considered in evaluating mergers, acquisitions and applications
to open a branch or new facility. Both banks' current CRA ratings are
"satisfactory."

        Banks are also subject to certain restrictions imposed by the Federal
Reserve Act on extensions of credit to executive officers, directors, principal
shareholders or any related interest of such persons. Extensions of credit (i)
must be made on substantially the same terms, including interest rates and
collateral as, and follow credit underwriting procedures that are not less
stringent than, those prevailing at the time for comparable transactions with
persons not affiliated with the bank, and (ii) must not involve more than the
normal risk of repayment or present other unfavorable features. Banks are also
subject to certain lending limits and restrictions on overdrafts to such
persons. A violation of these restrictions may result in the assessment of
substantial civil monetary penalties on the affected bank or any officer,
director, employee, agent or other person participating in the conduct of the
affairs of that bank, the imposition of a cease and desist order, and other
regulatory sanctions. Neither bank is aware of any material violation of these
laws and regulations.

        Under the Federal Deposit Insurance Corporation Improvement Act
("FDICIA"), each federal banking agency has prescribed, by regulation,
non-capital safety and soundness standards for institutions under its authority.
These standards cover internal controls, information and internal audit systems,
loan documentation, credit underwriting, interest rate exposure, asset growth,
compensation, fees and benefits, and standards for asset quality, earnings and
stock valuation. An institution which fails to meet these standards must develop
a plan acceptable to the agency, specifying the steps that the institution will
take to meet the standards. Failure to submit or implement such a plan may
subject the institution to regulatory sanctions. Management of both companies
believes that their companies and subsidiary banks are in substantial compliance
with these standards.



                                       103
<PAGE>   110

        Deposit and Account Insurance - The deposits of each bank are currently
insured to a maximum of $100,000 per depositor through the Bank Insurance Fund
("BIF"), administered by the FDIC. Each bank is required to pay semi-annual
deposit insurance premium assessments to the FDIC. The customer accounts of
Strand, Atkinson, Williams & York, Inc. are insured to a maximum of $100,000 for
any failure of the brokerage firm by the Securities Investors Protection
Corporation.

        Under the federal deposit insurance system, banks are assessed insurance
premiums according to how much risk they are deemed to present to the BIF. Banks
with higher levels of capital and a low degree of supervisory concern are
assessed lower premiums than banks with lower levels of capital or involving a
higher degree of supervisory concern. Both banks qualify for the lowest premium
level, and currently pay only the statutory minimum rate.


        Dividends - Under the Oregon Bank Act, a bank is subject to restrictions
on the payment of cash dividends to its shareholders, or in the case of South
Umpqua and Valley of the Rogue, parent company. A bank may not pay cash
dividends if that payment would reduce the amount of its capital below that
necessary to meet minimum applicable regulatory capital requirements. In
addition, the appropriate regulatory authorities are authorized to prohibit
banks and bank holding companies from paying dividends which would constitute an
unsafe or unsound banking practice.

        Capital Adequacy - The federal and state bank regulatory agencies use
capital adequacy guidelines in their examination and regulation of financial
holding companies, bank holding companies and banks. If the capital falls below
the minimum levels established by these guidelines, a holding company or a bank
may be denied approval to acquire or establish additional banks or non-bank
businesses or to open new facilities.

        The FDIC and Federal Reserve have adopted risk-based capital guidelines
for banks and holding companies. The risk-based capital guidelines are designed
to make regulatory capital requirements more sensitive to differences in risk
profile among banks and holding companies, to account for off-balance sheet
exposure and to minimize disincentives for holding liquid assets. Assets and
off-balance sheet items are assigned to broad risk categories, each with
appropriate weights. The resulting capital ratios represent capital as a
percentage of total risk-weighted assets and off-balance sheet items. The
current guidelines require all holding companies and federally-regulated banks
to maintain a minimum risk-based total capital ratio equal to 8%, of which at
least 4% must be Tier 1 capital. Generally, banking regulators expect banks to
maintain capital ratios well in excess of the minimum.

        Tier 1 capital for banks includes common shareholders' equity,
qualifying perpetual preferred stock (up to 25% of total Tier 1 capital, if
cumulative; under a Federal Reserve rule, redeemable perpetual preferred stock
may not be counted as Tier 1 capital unless the redemption is subject to the
prior approval of the Federal Reserve) and minority interests in equity accounts
of consolidated subsidiaries, less intangibles, except as described above. Tier
2 capital includes: (i) the allowance for loan losses of up to 1.25% of
risk-weighted assets; (ii) any qualifying perpetual preferred stock which
exceeds the amount which may be included in Tier 1 capital; (iii) hybrid capital
instruments (iv) perpetual debt; (v) mandatory convertible securities and (vi)
subordinated debt and intermediate term preferred stock of up to 50% of Tier 1
capital. Total capital is the sum of Tier 1 and Tier 2 capital less reciprocal
holdings of other banking organizations, capital instruments and investments in
unconsolidated subsidiaries.



                                       104
<PAGE>   111

        Banks' assets are given risk-weights of 0%, 20%, 50%, and 100%. In
addition, certain off-balance sheet items are given credit conversion factors to
convert them to asset equivalent amounts to which an appropriate risk-weight
will apply. These computations result in the total risk-weighted assets.

        Most loans are assigned to the 100% risk category, except for first
mortgage loans fully secured by residential property, which carry a 50% rating.
Most investment securities are assigned to the 20% category, except for
municipal or state revenue bonds, which have a 50% risk-weight, and direct
obligations of or obligations guaranteed by the U.S. Treasury or U.S. Government
agencies, which have 0% risk-weight. In converting off-balance sheet items,
direct credit substitutes, including general guarantees and standby letters of
credit backing financial obligations, are given 100% conversion factor. The
transaction-related contingencies such as bid bonds, other standby letters of
credit and undrawn commitments, including commercial credit lines with an
initial maturity of more than one year, have a 50% conversion factor.
Short-term, self-liquidating trade contingencies are converted at 20%, and
short-term commitments have a 0% factor.

        The FDIC also has implemented a leverage ratio, which is Tier 1 capital
as a percentage of total assets less intangibles, to be used as a supplement to
risk-based guidelines. The principal objective of the leverage ratio is to place
a constraint on the maximum degree to which a bank may leverage its equity
capital base. The FDIC requires a minimum leverage ratio of 3%. However, for all
but the most highly rated holding companies and for banks seeking to expand or
experiencing or anticipating significant growth, the FDIC requires a minimum
leverage ratio of 4%.

        The FDICIA created a statutory framework of supervisory actions indexed
to the capital level of the individual institution. Under regulations adopted by
the FDIC, an institution is assigned to one of five capital categories depending
on its total risk-based capital ratio, Tier 1 risk-based capital ratio, and
leverage ratio, together with certain subjective factors. Institutions which are
deemed to be "undercapitalized" are subject to certain mandatory supervisory
corrective actions. Both banks are considered well capitalized and management
does not believe that these regulations have any material effect on their
respective operations.

        As a registered broker-dealer, Strand, Atkinson, Williams & York, Inc.
is required to maintain capital levels adequate to cover its underwriting
activities. Since its acquisition by Umpqua, its current activities have not
been impeded by its capital level and Umpqua believes that its subsidiary's
capital position is adequate for its expected activities over the next year.

        Effects of Government Monetary Policy - The earnings and growth of the
companies are affected not only by general economic conditions, but also by the
fiscal and monetary policies of the federal government, particularly the Federal
Reserve. The Federal Reserve can and does implement national monetary policy for
such purposes as curbing inflation and combating recession, by its open market
operations in U.S. Government securities, control of the discount rate
applicable to borrowings from the Federal Reserve, and establishment of reserve
requirements against certain deposits. These activities influence growth of bank
loans, investments and deposits, and also affect interest rates charged on loans
or paid on deposits. The nature and impact of future changes in monetary
policies and their impact on the companies cannot be predicted with certainty.

        Changing Regulatory Structure of the Banking Industry - The laws and
regulations affecting banks and holding companies are subject to significant
change. Bills are now pending or expected to be introduced in the United States
Congress that contain proposals for altering the structure,



                                      105
<PAGE>   112

regulation, and competitive relationships of the nation's financial
institutions. If enacted into law, these bills could have the effect of
increasing or decreasing the cost of doing business, limiting or expanding
permissible activities, or affecting the competitive balance among banks,
savings associations, and other financial institutions. Some of these bills
would reduce (or, increase) the extent of federal deposit insurance, broaden the
powers or the geographical range of operations of holding companies, and realign
the structure and jurisdiction of various financial institution regulatory
agencies. Whether or in what form any such legislation may be adopted or the
extent to which the business of the companies might be affected thereby, cannot
be predicted with certainty.

        Of particular note is legislation enacted by Congress in 1995 permitting
interstate banking and branching, which allows banks to expand nationwide
through acquisition, consolidation or merger. Under this law, an adequately
capitalized holding company may acquire banks in any state or merge banks across
state lines if permitted by state law. Further, banks may establish and operate
branches in any state subject to the restrictions of applicable state law. Under
Oregon law, an out-of-state bank or holding company may merge with or acquire an
Oregon state chartered bank or holding company if the Oregon bank, or in the
case of a holding company, the subsidiary bank, has been in existence for a
minimum of three years, and the law of the state in which the acquiring bank is
located permits such merger. Branches may not be acquired or opened separately,
but once an out-of-state bank has acquired branches in Oregon, either through a
merger with or acquisition of substantially all the assets of an Oregon bank,
the acquirer may open additional branches.

        In December 1999, Congress enacted the Gramm-Leach-Bliley Act and
repealed the nearly 70-year prohibition on banks and bank holding companies
engaging in the businesses of securities and insurance underwriting imposed by
the Glass-Steagall Act.

        Under the GLB Act, a bank holding company may, if it meets certain
criteria, elect to be a "financial holding company," which is permitted to
offer, through a non-bank subsidiary, products and services that are "financial
in nature" and to make investments in companies providing such services. A
financial holding company may also engage in investment banking, and an
insurance company subsidiary of a financial holding company may also invest in
"portfolio" companies, without regard to whether the businesses of such
companies are financial in nature.

        The GLB Act also permits eligible banks to engage in a broader range of
activities through a "financial subsidiary," although a financial subsidiary of
a bank is more limited than a financial holding company in the range of services
it may provide. Financial subsidiaries of banks are not permitted to engage in
insurance underwriting, real estate investment or development, merchant banking
or insurance portfolio investing. Banks with financial subsidiaries must (i)
separately state the assets, liabilities and capital of the financial subsidiary
in financial statements; (ii) comply with operational safeguards to separate the
subsidiary's activities from the bank; and (iii) comply with statutory
restrictions on transactions with affiliates under Sections 23A and 23B of the
Federal Reserve Act.

        Activities that are "financial in nature" include activities normally
associated with banking, such as lending, exchanging, transferring and
safe-guarding money or securities, and investing for customers. Financial
activities also include the sale of insurance as agent (and as principal for a
financial holding company, but not for a financial subsidiary of a bank),
investment advisory services, underwriting, dealing or making a market in
securities, and any other activities previously determined by the Federal
Reserve to be permissible non-banking activities.



                                      106
<PAGE>   113

        Financial holding companies and financial subsidiaries of banks may also
engage in any activities that are incidental to, or determined by order of the
Federal Reserve to be complementary to, activities that are financial in nature.

        To be eligible to elect status as a financial holding company, a bank
holding company must be well-capitalized, under the Federal Reserve capital
adequacy guidelines, and to be well-managed, as indicated in the institution's
most recent regulatory examination. In addition, each bank subsidiary must also
be well-capitalized and well-managed, and must have received a rating of
"satisfactory" in its most recent CRA examination. Failure to maintain
eligibility would result in suspension of the institution's ability to commence
new activities or acquire additional businesses until the deficiencies are
corrected. The Federal Reserve could require a non-compliant financial holding
company that has failed to correct noted deficiencies within 180 days to divest
one or more subsidiary banks or to cease all activities other than those
permitted to ordinary bank holding companies under the regulatory scheme in
place prior to enactment of the GLB Act.

        In addition to expanding the scope of financial services permitted to be
offered by banks and bank holding companies, the GLB Act addressed the
jurisdictional conflicts between the regulatory authorities that supervise
various types of financial businesses. Historically, supervision was an
entity-based approach, with the Federal Reserve regulating member banks and bank
holding companies and their subsidiaries. As holding companies are now permitted
to have insurance and broker-dealer subsidiaries, the supervisory scheme is
oriented toward functional regulation. Thus, a financial holding company is
subject to regulation and examination by the Federal Reserve, but a
broker-dealer subsidiary of a financial holding company is subject to regulation
by the Securities and Exchange Commission, while an insurance company subsidiary
of a financial holding company would be subject to regulation and supervision by
the applicable state insurance commission.

        The GLB Act also includes provisions to protect consumer privacy by
prohibiting financial services providers, whether or not affiliated with a bank,
from disclosing non-public, personal, financial information to unaffiliated
parties without the consent of the customer, and by requiring annual disclosure
of the provider's privacy policy. Each functional regulator is charged with
promulgating rules to implement these provisions.


                          DESCRIPTION OF CAPITAL STOCK

UMPQUA

        The Articles of Incorporation of Umpqua authorize the issuance of up to
20 million shares of common stock with no par value and 2 million shares of
preferred stock with no par value. As of October 2, 2000, there were
______________ shares of common stock issued and outstanding. Following the
Merger, a total of approximately ______ shares are expected to issued and
outstanding. No preferred shares have been issued. Each outstanding share of
common stock has the same relative rights and preference as each other shares of
common stock, including the rights to the net assets of Umpqua upon liquidation.
Each share is entitled to one vote on matters submitted to a vote of
shareholders. Holders of common stock are not entitled to preemptive rights and
may not cumulate votes in the election of directors. All issued and outstanding
shares are, and all shares to be issued to VRB shareholders pursuant to the
Merger will be, fully paid and non-assessable. The terms of the preferred stock
are not established in the Articles, but may be designated in one or more series
by the Board of Directors when the shares are issued.



                                      107
<PAGE>   114

        The Board of Directors is authorized to issue or sell additional capital
stock of Umpqua, at its discretion and for fair value, and to issue future cash
or stock dividends, without prior shareholder approval except as otherwise
required by law or the listing requirements of the Nasdaq National Market.

        A total of 1,150,000 shares of common stock have been reserved for
issuance under Umpqua's existing stock option plan, of which ______ shares were
subject to options outstanding as of October 2, 2000. An additional
approximately ___________ shares will be subject to substitute options granted
to VRB stock option holders upon completion of the Merger. The maximum number of
options which may be issued pursuant to the plan is limited to 10% of the issued
and outstanding shares, excluding shares issued upon exercise of previously
granted options. The Umpqua shareholders are voting on a proposal at their
special meeting to approve a new stock option plan providing for grants of
options to acquire up to _______ shares.

VRB

        The Articles of Incorporation of VRB authorize the issuance of up to
30,000,000 shares of common stock with no par value and 10,000,000 shares of
preferred stock with a par value of $5.00 per share. As of October 2, 2000,
there were ______________ shares of common stock issued and outstanding. No
preferred shares have been issued. Each outstanding share of common stock has
the same relative rights and preference as each other shares of common stock,
including the rights to the net assets of VRB upon liquidation. Each share is
entitled to one vote on matters submitted to a vote of shareholders. Holders of
common stock are not entitled to preemptive rights and may not cumulate votes in
the election of directors. All issued and outstanding shares are fully paid and
non-assessable. The terms of the preferred stock are not established in the
Articles, but may be designated in one or more series by the Board of Directors
when the shares are issued.

        The Board of Directors is authorized to issue or sell additional capital
stock of VRB, at its discretion and for fair value, and to issue future cash or
stock dividends, without prior shareholder approval except as otherwise required
by law or the listing requirements of the Nasdaq National Market.

        A total of ___________ shares of common stock have been reserved for
issuance under VRB's stock option plans, of which ______ shares were subject to
options outstanding as of October 2, 2000.

ANTI-TAKEOVER PROVISIONS

        The Articles of Incorporation of Umpqua also authorize the Board of
Directors, when evaluating a merger, tender offer or exchange offer, to consider
the social, legal and economic effects on employees, customers and suppliers of
the company, and on the communities and geographical areas in which the company
operates, as well as the state and national economies and the short- and
long-term interests of the company and its shareholders. This provision may be
amended only by the affirmative vote of at least 75% of the outstanding shares.
Such provisions may have the effect of discouraging potential acquirors, and may
be considered anti-takeover defenses. Under the Oregon Business Act, a proposed
merger or plan of exchange requires the approval of the Board of Directors and
the affirmative vote of a majority of the outstanding shares.

        The articles of incorporation for both companies contain certain
provisions that could make more difficult their acquisition by means of an
unsolicited tender offer or proxy contest. The articles of incorporation of both
companies authorize the issuance of voting preferred stock, which, although
intended primarily as a financing tool and not as a defense against takeovers,
could



                                      108
<PAGE>   115

potentially be used by management to make more difficult uninvited attempts to
acquire control by, for example, diluting the ownership interest or voting power
of a substantial shareholder, increasing the consideration necessary to effect
an acquisition, or selling authorized but previously unissued shares to a
friendly third party. In addition, the articles of incorporation authorize the
issuance of warrants, rights, options or other obligations convertible into, or
entitling the holder thereof, to purchase shares of any class of stock, the
issuance of which may also have the effect of diluting the ownership interest of
a shareholder or increasing the consideration necessary to effect an acquisition
of a controlling interest in the companies.


                              CERTAIN LEGAL MATTERS

        The validity of Umpqua common stock to be issued in the Merger will be
passed upon for Umpqua by its counsel, Foster Pepper & Shefelman LLP, 101 SW
Main Street, Fifteenth Floor, Portland, Oregon.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

Umpqua Holdings Corporation (the Company) is a bank holding company formed in
March 1999. At that time, the Company acquired 100% of the outstanding shares of
South Umpqua Bank. The Company is headquartered in Roseburg, Oregon, and engages
primarily in the business of commercial and retail banking and the delivery of
retail brokerage services. The Company provides a wide range of banking, asset
management, mortgage banking, and other financial services to corporate,
institutional and individual customers through its wholly-owned banking
subsidiary South Umpqua Bank (the Bank). The Company engages in the retail
brokerage business through its wholly-owned subsidiary Strand, Atkinson,
Williams & York, Inc. The Company and its subsidiaries are subject to the
regulations of certain National and State agencies and undergo periodic
examinations by these regulatory agencies.

BASIS OF FINANCIAL STATEMENT PRESENTATION

The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles and with prevailing practices within
the banking and securities industries. In preparing such financial statements,
management is required to make certain estimates and judgments that affect the
reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities as of the date of the balance sheet ,and the reported amounts of
revenues and expenses for the reporting period. Actual results could differ
significantly from those estimates. Material estimates that are particularly
susceptible to significant change relate to the determination of the allowance
for loan losses.

CONSOLIDATION

The accompanying consolidated financial statements include the accounts of
Umpqua Holdings Corporation, South Umpqua Bank, and Strand, Atkinson, Williams &
York, Inc. All significant intercompany balances and transactions have been
eliminated in consolidation.

CASH AND CASH EQUIVALENTS

For purposes of the accompanying statements of cash flows, cash and cash
equivalents includes cash and due from banks, and interest-bearing balances due
from other banks.

TRADING ACCOUNT ASSETS

Debt securities held for resale are classified as trading account securities and
reported at fair value. Realized and unrealized gains or losses are recorded in
non-interest income.

INVESTMENT SECURITIES

Investment securities held-to-maturity are stated at cost, adjusted for
amortization of premiums and accretion of discounts. Securities
available-for-sale are stated at fair value. Gains and losses on sales of
securities, recognized on a specific identification basis, are included in
non-interest income. Net unrealized gain or loss on securities
available-for-sale are included, net of tax, as a component of shareholders'
equity. Mortgage-backed and related securities represent participating interests
in pools of mortgage loans originated and serviced by the issuers of the
securities. Premiums and discounts are amortized using a method that
approximates the level-yield method over the remaining period to contractual
maturity, adjusted for anticipated prepayments. Certain



                                      F-6
<PAGE>   122

                           UMPQUA HOLDINGS CORPORATION


obligations of U.S. Government agencies are callable by the agency. Premiums on
these securities are amortized using a method that approximates the level-yield
method over the remaining period to the first call date. Discounts are amortized
using a method that approximates the level-yield method over the remaining
period to scheduled maturity. The Company adopted Statement of Financial
Accounting Standard (SFAS) No. 133, Accounting for Derivative Instruments and
Hedging Activities, which establishes accounting and reporting standards for
derivative instruments and for hedging activities. It requires that an entity
recognize all derivatives as either assets or liabilities in the balance sheet
and measure those instruments at fair value. The accounting for changes in the
fair value of a derivative (that is, gains and losses) depends on the intended
use of the derivative and resulting designation. The Company adopted the
standard effective September 30, 1998. As permitted by the standard, the Company
transferred its held-to-maturity investment portfolio to the available-for-sale
designation, resulting in a charge to accumulated other comprehensive income of
$62,140, net of tax. The adoption of the statement did not have a material
impact on the consolidated financial position or financial results of the
Company.

LOANS HELD FOR SALE

Loans held for sale include mortgage loans and are reported at the lower of cost
or market value. Gains or losses on the sale of loans that are held for sale are
recognized at the time of the sale on a specific identification basis and
determined by the difference between net sale proceeds and the net book value of
the loans sold.

LOANS

Loans are reported net of unearned income. All discounts and premiums are
recognized over the life of the loan as yield adjustments.

IMPAIRED LOANS

Loans specifically identified as impaired are measured based on the present
value of expected future cash flows, discounted at the loans' observable market
price, or the fair value of the collateral if the loan is collateral dependent.
A loan is considered impaired when, based on current information and events, it
is probable that the Company will be unable to collect all amounts due according
to the contractual terms of the loan agreement, including scheduled interest
payments. If the measurement of the impaired loan is less than the recorded
investment in the loan, impairment is recognized by creating or adjusting an
existing allocation of the allowance for loan losses. Interest received on
impaired loans is applied first against the recorded impaired loan until paid in
full, next as a recovery up to any amounts charged off related to the impaired
loan, and finally as interest income.

ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses is established to absorb known and inherent losses
primarily resulting from loans outstanding and related off-balance sheet
commitments. Accordingly, all loan losses are charged to the allowance and all
recoveries are credited to it. The provision for loan losses charged to
operating expense is based on past loan loss experience and other factors which,
in management's judgment, deserve current recognition in estimating possible
loan losses. Such other factors include growth and composition of the loan
portfolio, credit concentrations, trends in portfolio volume, maturities,
delinquencies and non-accruals, the relationship of the allowance for loan
losses to outstanding loans, and general economic conditions. While management
uses the best information available to base its estimates, future adjustments to
the allowance may be necessary if economic conditions, particularly in the
Company's market, differ substantially from the



                                      F-7

assumptions used. In addition, various regulatory agencies, as an integral part
of their examination process, periodically review the Company's allowance for
loan losses. Such agencies may require the Company to recognize additions to the
allowance based on their judgments about information available to them at the
time of their examinations. The Company's principal lending activity is
concentrated in Douglas County, Lane County, and Multnomah County, Oregon.

LOAN FEES AND DIRECT LOAN ORIGINATION COSTS

Loan origination fees and direct loan origination costs are capitalized and
recognized as an adjustment to the yield over the life of the related loans.

NON-ACCRUAL LOANS

Commercial and real estate loans are placed on non-accrual status when they are
90 days past due as to principal or interest, unless the loan is both
well-secured and in process of collection. When a loan is placed on non-accrual
status, unpaid interest that is deemed uncollectible is reversed and charged
against current earnings, and all amortization of net deferred fees or costs is
discontinued.

INCOME TAXES

Income taxes are accounted for using the asset and liability method. Under this
method, a deferred tax asset or liability is determined based on the enacted tax
rates which will be in effect when the differences between the financial
statement carrying amounts and tax basis of existing assets and liabilities are
expected to be reported in the Company's income tax returns. The effect on
deferred taxes of a change in tax rates is recognized in income in the period
that includes the enactment date. Valuation allowances are established to reduce
the net carrying amount of deferred tax assets if it is determined to be more
likely than not that all or some portion of the potential deferred tax asset
will not be realized.

MORTGAGE SERVICING

Fees related to the servicing of mortgage loans of others are recorded as income
when payments are received. Late charges and miscellaneous other fees are
credited to income when collected. The costs of servicing loans are expensed as
incurred.

PREMISES, EQUIPMENT AND OTHER LONG-LIVED ASSETS

Company premises and equipment are stated at cost less accumulated depreciation
and amortization. Depreciation is provided over the estimated useful life of the
respective assets, 5 to 39 years, on a straight-line or accelerated basis.
Expenditures for major renovations and betterments of the Company's premises and
equipment are capitalized. In accordance with SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of,
management reviews long-lived assets and intangibles any time that a change in
circumstance indicates that the carrying amount of these assets may not be
recoverable. Recoverability of these assets is determined by comparing the
carrying value of the asset to the forecasted undiscounted cash flows of the
operation associated with the asset. If the evaluation of the forecasted cash
flows indicates that the carrying value of the asset is not recoverable, the
asset is written down to fair value. Goodwill, the price paid over the net fair
value of acquired businesses, is amortized on a straight-line basis over 15
years. Other intangible assets are amortized over their estimated useful lives
on a straight-line basis. Intangibles are evaluated periodically for impairment.

OTHER REAL ESTATE OWNED

Other real estate owned by the Company represents property acquired through
foreclosures or settlement of loans and is carried at the lower of the principal
amount of the loans outstanding at the time acquired or at the estimated fair
market value of the property. The Company had no other real estate owned at
December 31, 1999 or 1998.

PROFIT SHARING AND STOCK OPTION PLANS

The Company has a profit sharing plan covering substantially all its employees.
The contribution is determined annually by the Board of Directors at its
discretion. The Company grants stock options for a fixed number of shares to
employees with an exercise price equal to the closing market value of the shares
on the date of grant. The Company accounts for stock option grants in accordance
with APB Opinion 25, Accounting for Stock Issued to Employees, and accordingly
recognizes no compensation expense for the stock option grants.

COMPUTATION OF EARNINGS PER SHARE

Earnings per common share are based on the weighted average number of common and
common equivalent shares outstanding during each year.

FEDERAL HOME LOAN BANK STOCK

The Bank's investment in Federal Home Loan Bank (FHLB) stock is carried at par
value, which reasonably approximates its fair value. As a member of the FHLB
system, the Bank is required to maintain a minimum level of investment in FHLB
stock based on specific percentages of its outstanding mortgages, total assets,
or FHLB advances. At December 31, 1999, the Bank's minimum required investment
was approximately $2,008,000. The Bank may request redemption at par value of
any stock in excess of the minimum required investment. Stock redemptions are at
the discretion of the FHLB.

RECLASSIFICATIONS

Certain amounts reported in prior years' financial statements have been
reclassified to conform to the current presentation.

COMPREHENSIVE INCOME.

SFAS No. 130, Reporting Comprehensive Income, establishes standards for
reporting and displaying comprehensive income and its components in
general-purpose financial statements. Comprehensive income includes net income
and several other items that current accounting standards require to be
recognized outside of net income. This SFAS is effective for fiscal years
beginning after December 15, 1997, and as such, was adopted by the Company in
1998.

BUSINESS SEGMENTS

SFAS No. 131, Disclosure about Segments of an Enterprise and Related
Information, requires public enterprises to report certain information about
their operating segments in a complete set of financial statements to
shareholders. It also requires reporting of certain enterprise-wide information
about the Company's products and services, its activities in different
geographic areas, and its reliance on major customers. The basis for determining
the Company's operating segments is the manner in which management operates the
business. This SFAS is effective for financial statements for periods beginning
after December 15, 1997 and, as such, was adopted by the Company in 1998. The
Company has no foreign operations, no customers that provide more than 10
percent of gross revenue, and has determined that it has only one operating
segment.

NOTE 2 -- CASH AND DUE FROM BANKS

The Company is required to maintain an average reserve balance with the Federal
Reserve Bank or maintain such reserve balance in the form of cash. The amount of
average required reserve balance for the period including December 31, 1999 and
1998 was approximately $6,993,000 and $5,003,000, respectively, and was met by
holding cash and maintaining an average balance with the Federal Reserve Bank.

Investment securities having a carrying value of $19,412,725 and $10,980,722 at
December 31, 1999 and 1998, respectively, were pledged to secure public deposits
and for other purposes required or permitted by law.

The carrying value and fair value of debt securities at December 31, 1999 with
contractual maturity dates are shown below. Securities with serial maturities,
which include mortgage-backed securities, collateralized mortgage obligations,
and asset-backed securities, are detailed on a separate line. Serial maturities
will differ from contractual maturities because borrowers may have the right to
call or prepay obligations with or without call or prepayment penalties. Certain
obligations of U.S. Government agencies and states and political subdivisions
are callable by the applicable agency or political subdivision. These borrowers
also have the right to call or prepay obligations with or without call or
prepayment penalties.

loans to its directors, executive officers, principal shareholders and their
associated and affiliated companies ("related parties"). All such loans have
been made on the same terms as those prevailing at the time of origination to
other borrowers. At December 31, 1999 and 1998, outstanding loans to related
parties were $3,654,000 and $2,397,000, respectively.

There was no valuation allowance for deferred tax assets as of December 31,
1999, 1998 and 1997. The Company has deter-mined that it is not required to
establish a valuation allowance for the deferred tax assets as management
believes it is more likely than not that the deferred tax assets of $2,252,564,
$893,670 and $1,013,463 at December 31, 1999, 1998 and 1997, respectively, will
be realized principally through carrryback to taxable income in prior years,
future reversals of existing taxable temporary differences, and to a minor
extent, future taxable income. Management believes that future taxable income
will be sufficient to realize the benefits of temporary deductible differences
that cannot be realized through carryback to prior years or through the reversal
of future temporary taxable differences.

Interest on the above borrowings is due monthly with the principal due at
maturity, with the exception of the note due November 2003, where, in addition
to interest, a portion of the principal is due monthly. The $12,500,000 note,
scheduled to mature in December 2002, is callable on a quarterly basis by the
FHLB after March 2, 2000. The $3,000,000 note scheduled to mature in December
2003, is callable on a quarterly basis by the FHLB after June 11, 2000.

The Bank has pledged as collateral for these notes all FHLB stock, all funds on
deposit with the FHLB, all notes or other instruments representing obligations
of third parties, securities issued, insured or guaranteed by the United States
Government or any agency thereof, and its instruments, accounts, general
intangibles, equipment and other property in which a security interest can be
granted by the Bank to the FHLB. The Bank had unused lines of credit with the
FHLB of $42,079,000 at December 31, 1999. The Bank also had unused lines of
credit with financial institutions amounting to $18,366,000 at December 31,
1999. The FHLB requires the Bank to maintain a required level of investment in
FHLB stock to qualify for notes.


NOTE 13 -- SHAREHOLDERS' EQUITY

The Company had routinely transferred amounts in retained earnings to surplus to
increase its legal lending limit. It transferred $3,611,004 in 1997. Based on
changes made in the related regulations in late 1997, such transfers will no
longer be required as all elements of capital are now considered part of the
legal lending limit base. The Company is subject to various regulatory capital
requirements administered by the federal banking agencies. Failure to meet
minimum capital requirements can initiate certain mandatory and possible
additional discretionary actions by regulators that, if undertaken, could have a
material effect on the Company's financial statements. Under capital adequacy
guidelines and the regulatory framework for prompt corrective action, the
Company must meet specific capital guidelines that involve quantitative measures
of the

Company's assets, liabilities, and certain off-balance-sheet items as calculated
under regulatory accounting practices. The Company's capital amounts and
classifications are also subject to qualitative judgments by the regulators
about risk components, asset risk weighting, and other factors.

Risk-based capital guidelines issued by the Federal Reserve Bank establish a
risk adjusted ratio relating capital to different categories of assets and
off-balance-sheet exposures for bank holding companies. The Company's Tier 1
capital is comprised primarily of common equity, and excludes the equity impact
of adjusting available-for-sale securities to fair value. Total capital also
includes a portion of the allowance for loan losses, as defined according to
regulatory guidelines.

Quantitative measures established by regulation to ensure capital adequacy
require the Company to maintain minimum amounts and ratios (set forth in the
following table) of total and Tier I capital to risk-weighted assets (as defined
in the regulations), and of Tier I capital to average assets (as defined in the
regulations). Management believes, as of December 31, 1999, that the Company
meets all capital adequacy requirements to which it is subject.

The Company's actual capital amounts and ratios are presented in the following
table:

NOTE 14 - EMPLOYEE STOCK OPTION PLAN

The Company has an employee stock option plan whereby options may be granted to
its employees for up to 1,150,000 shares of common stock. Under the plan, the
exercise price of each option equals the market price of the Company's stock on
the date of the grant, and an option's maximum term is 11 years. Options vest
upon meeting performance criteria, but in all circumstances no later than six
years after the date of the grant. The following table summarizes information
about stock options outstanding at December 31, 1999, 1998 and 1997:

</TABLE>


The fair value per share of each option grant is estimated on the date of the
grant using the Black-Scholes option-pricing model with the following weighted
average assumptions for grants in 1999, 1998 and 1997: Dividend yield from 1.2%
to 2.9%, risk-free interest rate of 5.5%-6.0%, volatility of 0%-47% and expected
lives of six years.

The Company applies APB Opinion No. 25 in accounting for its plan; accordingly,
no compensation cost has been recognized for its stock option in the
accompanying consolidated financial statements because the stock options are
granted at the fair value of the stock on the date of the grant. Had the Company
determined compensation cost based on the fair value at the grant date for its
stock options under the Black-Scholes option-pricing model described above, as
permitted in SFAS No. 123, the Company's net income would have been reduced to
the pro forma amounts indicated in the following table:

NOTE 15 -- COMMITMENTS AND CONTINGENCIES

The Company and its subsidiaries are defendants in various legal proceedings.
Management, after reviewing these actions and proceedings with legal counsel,
believes that the outcome of such proceedings will not have a materially adverse
effect upon the financial position or results of operations of the Company and
its subsidiaries.

In the normal course of business, there are various commitments and contingent
liabilities outstanding, such as commitments to extend credit. At December 31,
1999 the Company had approximately $357,366 committed under standby letters of
credit. The Company issues these standby letters of credit using the same
guidelines as a direct loan. Management anticipates no material losses as a
result of these transactions.

At December 31, 1999 outstanding commitments to advance funds amounted to
approximately $68,735,000 of which approximately $18,703,000 were for fixed-rate
loans and approximately $50,032,000 were for variable-rate loans.

The following methods and assumptions were used to estimate the fair value of
each class of financial instrument for which it is practicable to estimate that
value. The estimated fair value amounts have been determined using available
market information and appropriate valuation methodologies. However,
considerable judgment is necessarily required to interpret market data to
develop the estimates of fair value. Potential tax ramifications related to the
realization of unrealized gains and losses that would be incurred in an actual
sale have not been taken into consideration.

CASH AND SHORT-TERM INVESTMENTS

For short-term instruments, including cash and due from banks, interest-bearing
deposits with banks, the carrying amount is a reasonable estimate of fair value.

SECURITIES

For trading securities and securities available-for-sale, fair values are based
on quoted market prices or dealer quotes.

LOANS

Fair values are estimated for portfolios of loans with similar financial
characteristics. Loans are segregated by type, including commercial, real estate
and consumer loans. Each loan category is further segregated by fixed and
variable rate, performing and non-performing categories. For variable-rate
loans, carrying value approximates fair value. Fair value of fixed-rate loans is
calculated by discounting contractual cash flows at rates which similar loans
are currently being made.

DEPOSIT LIABILITIES

The fair value of deposits with no stated maturity, such as non-interest-bearing
deposits, savings and interest checking accounts, and money market accounts, is
equal to the amount payable on demand as of December 31, 1999 and 1998. The fair
value of certificates of deposit is based on the discounted value of contractual
cash flows. The discount rate is estimated using the rates currently offered for
deposits of similar remaining maturities.

TERM DEBT

The fair value of medium-term notes is calculated based on the discounted value
of the contractual cash flows using current rates at which such borrowings can
currently be obtained.


NOTE 17 -- ACQUISITION OF STRAND, ATKINSON, WILLIAMS & YORK, INC.

In November 1999, the Company completed its acquisition of Strand, Atkinson,
Williams & York, Inc. Strand, Atkinson, Williams & York, Inc. provides a full
range of brokerage services to its clients. The results of operations of this
company are included in Umpqua Holdings Corporation for the month of December
1999. The acquisition was accounted for under the purchase method of accounting;
accordingly, the cost of the acquisition of $2,700,000 was allocated to the
assets acquired and liabilities assumed. The cost of intangible assets acquired
are being amortized over the life of such assets. The residual premium
(goodwill) is being amortized over 15 years, using the straight-line method. The
purchase agreement provides for future contingent payments to Strand, Atkinson,
Williams & York, Inc. shareholders if certain earnings objectives are achieved
by Strand, Atkinson, Williams & York, Inc. during the next three years. If these
contingent payments occur, they will be accounted for as additional goodwill and
will be amortized over the remaining life of the original goodwill. The
following table presents pro-forma results for 1999 and 1998 as if the
acquisition had occurred on January 1, 1998.

INDEPENDENT AUDITORS' REPORT


To the Shareholders and Board of Directors
  of Umpqua Holdings Corporation:

We have audited the accompanying consolidated balance sheets of Umpqua Holdings
Corporation and subsidiaries as of December 31, 1999 and 1998, and the related
consolidated statements of income, changes in shareholders' equity and
comprehensive income, and cash flows for each of the years in the three-year
period ended December 31, 1999. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Umpqua Holdings
Corporation and subsidiaries as of December 31, 1999 and 1998, and the results
of their operations and their cash flows of each of the years in the three-year
period ended December 31, 1999 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                            (JUNE 30, 2000 UNAUDITED)




NOTE 1 -- ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of VRB
Bancorp (VRB), a bank holding company, and its wholly-owned subsidiary, Valley
of the Rogue Bank (the Bank). Substantially all activity of VRB is conducted
through its subsidiary bank and all significant intercompany accounts and
transactions have been eliminated in the preparation of the consolidated
financial statements.

DESCRIPTION OF BUSINESS

The Bank is a state-chartered institution authorized to provide banking services
by the State of Oregon. With its headquarters in Rogue River, Oregon, it also
has branch operations in Josephine and Jackson County, Oregon. The Bank conducts
a general banking business. Its activities include the usual deposit functions
of a commercial bank: commercial, real estate, installment, and mortgage loans;
checking and savings accounts; automated teller machines (ATM's); collection
services; and, safe deposit facilities. Both VRB Bancorp and Valley of the Rogue
Bank are subject to the regulations of certain Federal and State agencies and
undergo periodic examinations by those regulatory authorities.

MANAGEMENT'S ESTIMATES AND ASSUMPTION

In preparing the consolidated financial statements, management is required to
make estimates and assumptions that affect the reported amounts of assets and
liabilities as of the date of the balance sheet and revenues and expenses for
the period. Actual results could differ significantly from those estimates.

INVESTMENT SECURITIES

The Bank is required to specifically identify under generally accepted
accounting principles its investment securities as "held-to-maturity,"
"available-for-sale," or "trading accounts." Accordingly, management has
determined that all investment securities held at December 31, 1999 and 1998,
are either "available-for-sale" or "held-to-maturity" and conform to the
following accounting policies:

SECURITIES HELD-TO-MATURITY

Bonds, notes, and debentures for which the Bank has the intent and ability to
hold to maturity are reported at cost, adjusted for premiums and discounts that
are recognized in interest income using the interest method over the period to
maturity.

SECURITIES AVAILABLE-FOR-SALE

Available-for-sale securities consist of bonds, notes, debentures, and certain
equity securities not classified as held-to-maturity securities. Securities are
generally classified as available-for-sale if the instrument may be sold in
response to such factors as: (1) changes in market interest rates and related
changes in the security's prepayment risk, (2) needs for liquidity, (3) changes
in the availability of and the yield on alternative instruments, and (4) changes
in funding sources and

                                  VRB BANCORP

terms. Unrealized holding gains and losses, net of tax, on available-for-sale
securities are reported as a net amount in a separate component of equity until
realized. Fair values for investment securities are based on quoted market
prices. Gains and losses on the sale of available-for-sale securities are
determined using the specific-identification method.

Declines in the fair value of individual held-to-maturity and available-for-sale
securities below their cost that are other than temporary, result in write-downs
of the individual securities to their fair value. The related write-downs would
be included in earnings as realized losses. Premiums and discounts are
recognized in interest income using the interest method over the period to
maturity.

LOANS, NET OF ALLOWANCE FOR LOAN LOSSES AND UNEARNED INCOME

Loans are stated at the amount of unpaid principal, reduced by an allowance for
loan losses and unearned income. Interest on loans is calculated by using the
simple-interest method on daily balances of the principal amount outstanding.
The allowance for loan losses is established through a provision for loan losses
charged to expenses. Loans are charged against the allowance for loan losses
when management believes that the collectibility of the principal is unlikely.
The allowance is an amount that management believes will be adequate to absorb
possible losses on existing loans that may become uncollectible, based on
evaluations of the collectibility of loans and prior loan loss experience. The
evaluations take into consideration such factors as changes in the nature and
volume of the loan portfolio, overall portfolio quality, review of specific
problem loans, and current economic conditions that may affect the borrower's
ability to pay. Various regulatory agencies, as an integral part of their
examination process, periodically review the Bank's reserve for loan losses.
Such agencies may require the Bank to recognize additions to the reserve based
on their judgment of information available to them at the time of their
examinations.

Loans receivable that will not be repaid in accordance with their contractual
terms are measured using a discounted cash flow methodology or the fair value of
the collateral for certain loans. Accrual of interest is discontinued on
impaired loans when management believes, after considering economic and business
conditions, collection efforts, and collateral position that the borrower's
financial condition is such that collection of interest is doubtful. When
interest accrual is discontinued, all unpaid accrued interest is reversed.
Interest income is subsequently recognized only to the extent cash payments are
received.

Loan origination fees and certain direct origination costs are capitalized and
recognized as an adjustment to the yield of the related loan.

PREMISES AND EQUIPMENT

Premises and equipment are stated at cost, less accumulated depreciation.
Depreciation is computed principally by the straight-line method over the
estimated useful lives of the assets. Depreciation is based on useful lives of 3
to 25 years on furniture and equipment; 15 to 40 years for buildings and
components; and, 15 to 20 years on leasehold improvements.

OTHER REAL ESTATE

Real estate acquired by the Bank in satisfaction of debt is carried at the lower
of cost or estimated net realizable value. When property is acquired, any excess
of the loan balance over its estimated net realizable value is charged to the
allowance for loan losses. Subsequent write-downs to net realizable value, if
any, or any disposition gains or losses are included in noninterest income and
expense.

GOODWILL

Goodwill represents the costs in excess of net assets acquired arising
principally from the purchase of Colonial Banking Company (see Note 2), and is
being amortized over 15 years.

INCOME TAXES

Deferred income tax assets and liabilities are determined based on the tax
effects of differences between the book and tax bases of the various balance
sheet assets and liabilities. Deferred tax assets and liabilities are reflected
at currently enacted income tax rates applicable to the period in which the
deferred tax assets or liabilities are expected to be realized or settled. As
changes in tax laws or rates are enacted, deferred tax assets and liabilities
are adjusted through the provision for income taxes.

STATEMENT OF CASH FLOWS

Cash equivalents are generally all short-term investments with a maturity of
three months or less. Cash and cash equivalents normally include cash on hand,
amounts due from banks, and federal funds sold.

OFF-BALANCE-SHEET FINANCIAL INSTRUMENTS

The Bank holds no derivative financial instruments. However, in the ordinary
course of business, the Bank enters into off-balance-sheet financial instruments
consisting of commitments to extend credit as well as commercial letters of
credit and standby letters of credit. Such financial instruments are recorded in
the financial statements when they are funded or related fees are incurred or
received.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by the Bank in estimating fair
values of financial instruments as disclosed herein:

        Cash and cash equivalents -- The carrying amounts of cash and short-term
        instruments approximate their fair value.

        Held-to-maturity and available-for-sale securities -- Fair values for
        investment securities, excluding restricted equity securities, are based
        on quoted market prices. The carrying values of restricted equity
        securities approximate fair values.

        Loans receivable -- For variable-rate loans that reprice frequently and
        have no significant change in credit risk, fair values are based on
        carrying values. Fair values for certain mortgage loans (for example,
        one-to-four family residential), credit card loans, and other consumer
        loans are based on quoted market prices of similar loans sold in
        conjunction with securitization transactions, adjusted for differences
        in loan characteristics. Fair values for commercial real estate and
        commercial loans are estimated using discounted cash flow analyses,
        using interest rates currently being offered for loans with similar
        terms to borrowers of similar credit quality. Fair values for impaired
        loans are estimated using discounted cash flow analyses or underlying
        collateral values, where applicable.

        Deposit liabilities -- The fair values disclosed for demand deposits
        are, by definition, equal to the amount payable on demand at the
        reporting date (that is, their carrying amounts). The carrying amounts
        of variable-rate, fixed-term money market accounts and certificates of
        deposit (CDs) approximate their fair values at the reporting date. Fair
        values for fixed-rate CDs are estimated using a discounted cash flow
        calculation that applies interest rates



                                      F-33

<PAGE>   149
                                  VRB BANCORP


        currently being offered on certificates to a schedule of aggregated
        expected monthly maturities on time deposits.

        Short-term borrowings -- The carrying amounts of federal funds
        purchased, borrowings under repurchase agreements, and other short-term
        borrowings maturing within 90 days approximate their fair values. Fair
        values of other short-term borrowings are estimated using discounted
        cash flow analyses based on the Bank's current incremental borrowing
        rates for similar types of borrowing arrangements.

        Long-term debt -- The fair values of the Bank's long-term debt are
        estimated using discounted cash flow analyses based on the Bank's
        current incremental borrowing rates for similar types of borrowing
        arrangements.

        Accrued interest -- The carrying amounts of accrued interest approximate
        their fair values.

        Off-balance-sheet instruments -- The Bank's off-balance-sheet
        instruments include unfunded commitments to extend credit and standby
        letters of credit. The fair value of these instruments is not considered
        practicable to estimate because of the lack of quoted market prices and
        the inability to estimate fair value without incurring excessive costs.

ADVERTISING

Advertising costs are charged to expense during the year in which they are
incurred. Advertising expenses were $137,276, $169,524, and $114,670 for the
years ended December 31, 1999, 1998, and 1997, respectively.

STOCK OPTIONS

VRB applies Accounting Principles Board Opinion 25 and related interpretations
in accounting for its stock option plans. Accordingly, compensation costs are
recognized as the difference between the exercise price of each option and the
market price of VRB's stock at the date each grant becomes further vested.
Accordingly, compensation costs charted to income were $89,673, $93,340, and
$57,312 in 1999, 1998, and 1997, respectively. Had compensation for VRB's stock
option plans been determined based on the fair value at the grant dates for
awards under those plans consistent with the method of Statement of Financial
Accounting Standards No. 123, the Bank's net income would have been affected as
described in Note 14.

RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1999, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standard (SFAS) No. 137 "Accounting for Derivative
Instruments and Hedging Activities -- Deferral of the Effective Date of FASB
Statement No. 133." SFAS No. 133 establishes accounting and reporting standards
for derivative instruments, including certain derivative instruments embedded in
other contracts, (collectively referred to as derivatives) and for hedging
activities. It requires that VRB recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. If certain conditions are met, a derivative may be specifically
designated as (a) a hedge of the exposure to changes in the fair value of a
recognized asset or liability or an unrecognized firm commitment (b) a hedge of
the exposure to variable cash flows of a forecasted transaction, or (c) a hedge
of the foreign currency exposure of a net investment in a foreign operation, an
unrecognized firm commitment, an available-for-sale security, or a
foreign-currency-denominated forecasted transaction. SFAS No. 133, as amended by
SFAS No. 137, shall be effective for all fiscal quarters of all fiscal years


                                      F-34
<PAGE>   150

                                   VRB BANCORP


beginning after June 15, 2000. However, management of VRB believes this
accounting standard will have no effect on the financial condition and results
of operation of the Bank.

Other issued but not yet required FASB statements are not currently applicable
to the Bank's operations. Management believes these pronouncements will also
have no material effect upon VRB's financial position or results of operation.

RECLASSIFICATIONS

Certain reclassifications have been made to the 1998 and 1997 consolidated
financial statements to conform with current year presentations.

INTERIM FINANCIAL STATEMENTS

The unaudited consolidated financial statements for June 30, 1999 and 2000 and
the six month periods then ended have been prepared in accordance with generally
accepted accounting principles for interim financial information and in
compliance with instructions to Form 10-Q and Rule 10-01 of Regulation S-X.
Adjustments to the interim financial statements are of a normal recurring nature
and include all adjustments that, in the opinion of management, are necessary to
the fair presentation of the financial position and operating results for the
interim periods. The operating results for the six months ended June 30, 2000
and not necessarily indicative of the results that may be expected for the
entire fiscal year ending December 31, 2000 or any other future interim period.
See VRB's Management's Discussion and Analysis for further interim information.


NOTE 2 -- ACQUISITION OF COLONIAL BANKING COMPANY

VRB Bancorp completed its acquisition of Colonial Banking Company (CBC)
effective January 5, 1998. VRB paid former stockholders of CBC $15.7 million in
cash for the common and preferred stock of CBC. This acquisition was treated as
a purchase for accounting purposes. Accordingly, under generally accepted
accounting principles, the assets and liabilities of CBC have been recorded on
the books of the Bank at their respective fair market values at the effective
date the acquisition was consummated. Goodwill, the excess of the purchase price
over the net fair value of the assets and liabilities acquired, was recorded at
$9.5 million. Amortization of goodwill over a 15-year period will result in a
charge to earnings of approximately $635,000 per year.

The following are the fair values of assets acquired and liabilities assumed as
of the January 5, 1998, acquisition date (in thousands):

contractual maturities of underlying collateral. Collateralized mortgage
obligations may mature earlier than their weighted-average contractual
maturities because of principal prepayments.

At December 31, 1999 and 1998, investment securities with an amortized cost of
$6,185,993 and $8,168,284, respectively, were pledged to secure public deposits

The Bank's recorded investment in impaired loans was $523,857 and $262,456 at
December 31, 1999 and 1998, respectively. The average recorded investment in
impaired loans approximates their recorded investment at December 31, 1999 and
1998. The total allowance for loan losses related to these loans at December 31,
1999 and 1998, was approximately $70,000 and $42,000, respectively. Interest
income recognized on impaired loans during the years ended December 31, 1999,
1998, and 1997, was not significant. Management estimates that in 1999,
approximately $42,600 of interest income was not recognized on impaired loans on
nonaccrual status, compared with approximately $35,300 in 1998 and $29,600 in
1997.

</TABLE>

        The exercise of stock options which have been granted under VRB
Bancorp's stock option plan for directors give rise to compensation which is
includable in the taxable income of the applicable employees and deductible by
the Bank for federal and state income tax purposes. Such compensation results
from increases in the fair market value of VRB Bancorp's common stock subsequent
to the date of grant of the applicable exercised stock options and, accordingly,
in accordance with APB Opinion No. 25, such compensation is not recognized as an
expense for financial accounting purposes and the related tax benefits are taken
directly to common stock. For the years ended December 31, 1998 and 1997, these
transactions resulted in federal and state tax deductions and benefits, which
have increased common stock.

        Management believes, based upon the Bank's historical performance, that
net deferred tax assets will be realized in the normal course of operations and,
accordingly, management has not reduced net deferred tax assets by a valuation
allowance.

        The tax provision differs from the federal statutory rate of 34% due
principally to tax exemptions for interest received on municipal investments and
nondeductible goodwill expense amortization. The 1997 provision for income taxes
reflects a reduction in the state income tax rate from 6.6% to 3.8%.

NOTE 9 -- FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

        The Bank is a party to financial instruments with off-balance-sheet risk
in the normal course of business to meet the financing needs of its customers.
These financial instruments include commitments to extend credit and standby
letters of credit and financial guarantees. Those instruments involve elements
of credit and interest-rate risk similar to the amounts recognized in the
consolidated balance sheets. The contract or notional amounts of those
instruments reflect the extent of the Bank's involvement in particular classes
of financial instruments.

        The Bank's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend credit and
standby letters of credit, and financial guarantees written, is represented by
the contractual notional amount of those instruments. The Bank uses the same
credit policies in making commitments and conditional obligations as it does for
on-balance-sheet instruments.

        Commitments to extend credit are agreements to lend to a customer as
long as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since many of the commitments are expected to
expire without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. The Bank's experience has been that a
majority of loan commitments are drawn upon by customers. While most commercial
letters of credit are not utilized, a significant portion of such utilization is
on an immediate payment basis. The Bank evaluates each customer's
creditworthiness on a case-by-case basis. The amount of collateral obtained, if
it is deemed necessary by the Bank upon extension of credit, is based on
management's credit evaluation of the counterparty. Collateral varies but may
include cash, accounts receivable, inventory, premises and equipment, and
income-producing commercial properties.

        Standby letters of credit and financial guarantees written are
conditional commitments issued by the Bank to guarantee the performance of a
customer to a third-party. These guarantees are primarily issued to support
public and private borrowing arrangements, including commercial paper, bond
financing, and similar transactions. The credit risk involved in issuing letters
of credit is essentially the same as that involved in extending loan facilities
to customers. The Bank holds cash, marketable securities, or real estate as
collateral supporting those commitments for which collateral is deemed
necessary.

        While estimates of fair value are based on management's judgment of the
most appropriate factors, there is no assurance that were the Bank to have
disposed of such assets or liabilities at December 31, 1999 and 1998, the
estimated fair values would necessarily have been realized at that date, since
market values may differ depending on various circumstances. The estimated fair
values at December 31, 1999 and 1998, should not necessarily be considered to
apply at subsequent dates.

        In addition, other assets and liabilities of the Bank that are not
defined as financial instruments are not included in the above disclosures, such
as premises and equipment. Also, nonfinancial instruments typically not
recognized in the financial statements nevertheless may have value but are not
included in the above disclosures. These include, among other items, the
estimated earnings power of core deposit accounts, the earnings potential of
loan servicing rights, the trained work force, customer goodwill, and similar
items.

NOTE 11 - CONCENTRATIONS OF CREDIT RISK

        All of the Bank's loans, commitments, and commercial and standby letters
of credit have been granted to customers in the Bank's market area. Investments
in state and municipal securities are not significantly concentrated within any
one region of the United States. The concentrations of credit by type of loan
are set forth in Note 4. The distribution of commitments to extend credit
approximates the distribution of loans outstanding. Commercial and standby
letters of credit were granted primarily to commercial borrowers as of December
31, 1999. The Bank's loan policy does not allow the extension of credit to any
single borrower or group of related borrowers in excess of a total of $1,250,000
without approval from the Board of Directors.


NOTE 12 - COMMITMENTS AND CONTINGENCIES

        LITIGATION - In the ordinary course of business, the Bank becomes
involved in various litigation arising from normal banking activities. In the
opinion of management, the ultimate disposition of these actions will not have a
material adverse effect on the consolidated financial position or results of
operations.

        OPERATING LEASES - The Bank leases certain branch premises and
equipment. The following is a schedule of future minimum lease payments under
operating leases in effect as of December 31, 1999:

        YEAR 2000 - Because of the unprecedented nature of the Year 2000 issue,
its effects, if any, may not be identified until a future date. Management
cannot assure that VRB or the Bank have has identified all Year 2000 issues,
that VRB's or the Bank's remediation efforts has been successful in whole or in
part, or that parties with whom VRB or the Bank does business will not be
significantly impacted by Year 2000 issues.


NOTE 13 - BORROWING AGREEMENTS

        The Bank has federal fund borrowing agreements with Bank of America and
Wells Fargo Bank for $5,000,000 and $3,000,000, respectively. There is no stated
rate of interest on these borrowings. As of December 31, 1999, there were no
borrowings outstanding under these agreements.

        The Bank also participates in the Cash Management Advance Program with
the Federal Home Loan Bank of Seattle (FHLB). Under the program, the Bank may
borrow to a maximum of 10% of total assets (approximately $30 million at
December 31, 1999 and 1998) with interest at the

FHLB's cash management rate. There were no borrowings outstanding at December
31, 1999 and 1998.


NOTE 14 -- STOCK OPTION PLANS

        The Bank has two stock option plans, which were approved by the
shareholders during 1991 and amended in 1994. The plans provide for an aggregate
of 754,514 shares of the Bank's unissued common stock to be granted to key
employees and nonemployee directors. The 1994 amendment removed the requirement
for a five-year vesting schedule for any future grants from the Employees' Plan,
thus leaving the setting of any vesting schedule to the discretion of the Board
of Directors. The Directors' Plan was amended to extend the time in which
options may be exercised following resignation or retirement.

        With the exception of certain options granted to nonemployee directors,
all options granted and outstanding under both the Directors' and Employees'
Plans are noncompensatory and exercisable at purchase prices which approximate
fair value on the date of grant. Because certain options granted to the Bank's
directors were based on purchase prices below the fair value of the stock as of
the grant date, they are considered compensatory transactions and give rise to
the recognition of compensation expense. Accordingly, the Bank has recognized
$89,763, $93,340, and $57,312 as compensation expense relating to $15,695,
16,851, and 18,790 shares of common stock optioned to its directors during 1999,
1998, and 1997, respectively.

        The following summarizes options available and outstanding under both
the Directors' and Employees' Plans as of December 31, 1999, after the effect of
the current year's stock dividend (in thousands with the exception of the
exercise price):

        The fair value of options granted is estimated on the date of grant
using the Black-Scholes option-pricing model with the following assumptions: (1)
dividend yields of 3.24% in 1999, 5.75% in 1998, and 1.52% in 1997; (2) expected
volatility of 28.57% in 1999, 18.35% in 1998, and 28.00% in 1997; (3) risk-free
rates of 6.50% in 1999, 4.75% in 1998; and 6.50% in 1997; and, (4) expected life
of one to ten years for all three years.

        The effects of applying SFAS No. 123 in this pro forma disclosure are

NOTE 15 -- EMPLOYEE BENEFIT PLANS

        The Bank has a defined contribution profit sharing plan. All permanent
employees are eligible to participate once they meet the age and length of
employment requirements. Contributions are determined annually by the Board of
Directors and were $337,418, $313,562, and $168,557 in 1999, 1998, and 1997,
respectively, excluding additional amounts set aside for funding through the
Bank's bonus program. Voluntary employee contributions are required to share in
Bank contributions. Employee contributions were $222,313, $226,381, and $189,640
in 1999, 1998, and 1997, respectively.

        The Bank has established a bonus program as part of the compensation
package it provides to employees. At December 31, 1999, the Bank employed
approximately 190 individuals eligible to participate in this program. Under the
program, a bonus pool for nonexecutives is established and funded based on net
profits of the current and immediately preceding year. An executive bonus
program is similarly funded and is based on current year profits with payments
measured on the basis of return on assets. For the years ending December 31,
1999, 1998, and 1997, $660,000, $620,000, and $542,400, respectively, was
expensed to fund these programs with their related payroll and benefit costs.

        The Bank has also established supplemental retirement agreements with
certain executive officers. The agreements provide for established
post-retirement payments to covered executives for up to ten years after their
retirement. The supplemental programs are self-funded by the Bank through the
setting aside of funds into a bank-controlled deposit account. As of December
31, 1999, a liability for the supplemental retirement plans was recognized and
funded in the amount of $225,736. During 1999, 1998, and 1997, the Bank recorded
Plan expenses of $38,600, $38,600, and $21,000, respectively.

        Basic earnings per share excludes dilution and is computed by dividing
income available to common stockholders by the weighted average number of common
shares outstanding for the year. Diluted earnings per share reflect the
potential dilution that could occur if common shares were issued pursuant to the
exercise of options under the Bank's stock option plans. Comparative earnings
per share data for the years ended December 31, 1998 and 1997, have been
restated to conform with the current year presentation. The following table
illustrates the computations of basic and diluted earnings per share for the six
months ended June 30, 2000 and 1999 (unaudited) and the years ended December 31,
1999, 1998, and 1997 (dollars in thousands except per share amounts):

NOTE 17 -- TRANSACTIONS WITH RELATED PARTIES

        Certain directors, executive officers, and principal stockholders are
customers of and have had banking transactions with the Bank in the ordinary
course of business, and the Bank expects to have such transactions in the
future. All loans and commitments to loan included in such transactions were
made in compliance with applicable laws on substantially the same terms
(including interest rates and collateral) as those prevailing at the time for
comparable transactions with other persons and, in the opinion of the management
of the Bank, do not involve more than the normal risk of collectibility or
present any other unfavorable features. The amount of loans outstanding to

they are associated was as follows:

NOTE 18 -- REGULATORY MATTERS

        VRB Bancorp and the Bank are subject to various regulatory capital
requirements administered by federal banking agencies. Failure to meet minimum
capital requirements can initiate certain mandatory - and possibly additional
discretionary - actions by regulators that, if undertaken, could have a direct
material effect on VRB Bancorp and the Bank's financial statements. Under
capital adequacy guidelines and the regulatory framework for prompt corrective
action, VRB Bancorp and the Bank must meet specific capital guidelines that
involve quantitative measures of assets, liabilities, and certain
off-balance-sheet items as calculated under regulatory accounting practices.
Capital amounts and classification are also subject to qualitative judgments by
the regulators about components, risk weightings, and other factors.

        Quantitative measures established by regulation to ensure capital
adequacy require VRB Bancorp and the Bank to maintain minimum amounts and ratios
(set forth in the table below) of



                                      F-47

total and Tier 1 capital (as defined in the regulations) to risk-weighted assets
(as defined), and of Tier 1 capital to average assets (as defined). Management
believes, as of December 31, 1999, that VRB Bancorp and the Bank meet all
capital adequacy requirements to which they are subject.

        As of December 31, 1999, the most recent notification from the Office of
the Comptroller of the Currency categorized the Bank as well capitalized under
the regulatory framework for prompt corrective action. To be categorized as well
capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based,
and Tier 1 leverage ratios as set forth in the table. There are no conditions or
events since that notification that management believes have changed the
institution's category. VRB Bancorp's capital ratios are not significantly
different from those of the Bank.

NOTE 20 -- STOCK OFFERING

        During November 1997, the Bank registered 1,150,000 shares of common
stock for sale to the public at a price of $8.50 per share, for an aggregate
offering price of $9,775,000. All shares were sold, resulting in net proceeds of
$8,784,104, after deducting $990,896 for underwriting discounts and commissions,
legal, accounting and printing fees, and other offering expenses. Net proceeds
to the Bank were used in connection with the acquisition of Colonial Banking
Company in early January 1998 (see Note 2). Pending such use, the net proceeds
were invested in short-term, investment-grade securities.

INDEPENDENT AUDITOR'S REPORT





To the Board of Directors
  and Shareholders of VRB Bancorp



We have audited the accompanying consolidated balance sheets of VRB Bancorp as
of December 31, 1999 and 1998, and the related statements of income and
comprehensive income, changes in shareholders' equity, and cash flows for the
years ended December 31, 1999, 1998, and 1997. These financial statements are
the responsibility of VRB Bancorp's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of VRB Bancorp as of
December 31, 1999 and 1998, and the results of its operations and cash flows for
each of the years in the three-year period ended December 31, 1999, in
conformity with generally accepted accounting principles.

               succeed any VRB Designee; and (iv) a change to the Articles of
               Incorporation or Bylaws of Umpqua or the Surviving Bank which

               own, lease, and operate its properties and assets and carry on
               its business in the manner now being conducted. Valley is a bank
               duly organized, validly existing, and in good standing under the
               laws of the State of Oregon and has all requisite corporate power
               and authority to own, lease, and operate its properties and
               assets and carry on its business in the manner now being

               is in good standing in every jurisdiction in which such
               qualification is required except where the failure to so qualify
               would not result in any material adverse effect on its business
               operation, financial condition or properties.

               investment securities from any holder, are authorized, issued or
               outstanding.

        4.3.   Public Reports. Since January 1, 1997, VRB has timely filed with
               the SEC all reports and statements required to be filed pursuant
               to the Exchange Act (the "VRB Public Reports"). Until the
               Effective Date, VRB will file with the SEC (and will furnish
               copies to Umpqua within two days thereafter) all additional
               reports and other documents which VRB is required by the Exchange
               Act to file or otherwise files with the SEC. The financial
               information included in the VRB Public Reports has been and will
               be prepared in accordance with generally accepted accounting
               principles, consistently applied, and present fairly the
               financial position and results of operation of VRB and its
               subsidiaries on the dates and for the periods covered thereby. As
               of the date filed, each VRB Public Report has been and, as to
               those reports to be filed on or after the date of this Agreement
               and the Closing, will be accurate and complete as of the date
               filed, and each complies or will comply with all requirements
               applicable to such filing.

        4.4.   Articles of Incorporation, Bylaws, Minutes. The copies of the
               Articles of Incorporation, as amended, and the Bylaws of each of

               correct and complete copies of existing Articles of Incorporation
               and Bylaws of VRB and Valley, as the case may be, as amended to
               date. Neither VRB nor Valley is in violation of any provision of
               its Articles of Incorporation or Bylaws. The minute books of VRB
               and Valley which have been or will be made available to Umpqua
               for its review contain accurate and complete minutes of all
               meetings and all consents evidencing actions taken without a
               meeting by its Board of Directors (and any committees thereof)
               and by its shareholders.

        4.5.   No Holding Company, Joint Venture, or Other Subsidiaries. Other
               than as to VRB with respect to Valley, no corporation or other
               entity is registered or, to the knowledge of VRB or Valley, is
               required to be registered as a bank holding company under the
               Bank Holding Company Act of 1956, as amended, because of
               ownership or control of VRB or Valley. Neither VRB nor Valley,
               directly or indirectly, owns or controls, either by power to
               control the investment or power to vote, any shares of capital
               stock of any other corporation or entity, other than

                                     App-7

               shares held in a fiduciary or custodial capacity in the ordinary
               course of business and shares representing less than five percent
               of the outstanding shares of such corporation acquired in partial
               or full satisfaction of debts previously contracted. Neither VRB
               nor Valley is a part of any joint venture, or general or limited
               partnership, or a member of any unincorporated association.

        4.6.   Shareholder Reports. VRB has delivered to Umpqua as Schedule 4.6
               copies of all of VRB's reports and other communications to
               stockholders since January 1, 1999, including all proxy
               statements and notices of shareholder meetings, to the extent
               such reports and communications have not been filed with any VRB
               Public Reports. Until the Effective Date, VRB will furnish to
               Umpqua copies of all future communications within two days such
               materials are first sent to its shareholders.

        4.7.   Books and Records. The books and records of VRB and Valley
               accurately reflect in all material respects the transactions to
               which it is a party or by which it or its properties are bound or
               subject. Such books and records have been and are accurate and
               complete and comply in all material respects with applicable
               legal, regulatory and accounting requirements.

        4.8.   Legal Proceedings. Except for regulatory examinations conducted
               in the normal course of regulation of VRB and Valley, and except
               as disclosed in Schedule 4.8 delivered to Umpqua, there are no
               actions, suits, proceedings, claims or governmental
               investigations pending or, to the knowledge of VRB, threatened
               against or affecting VRB before any court, administrative officer
               or agency, other governmental body or arbitration which might,
               individually or in the aggregate, result in any material adverse
               change in the business, assets, earnings, operation or condition
               (financial or otherwise) of VRB or which might hinder or delay
               the consummation of the transactions contemplated by this
               Agreement.

        4.9.   Compliance with Lending Laws and Regulations. Except as disclosed
               in Schedule 4.9 and except for such errors or oversights the
               financial effect of which are adequately reserved against:

               (a) The conduct by each of VRB and Valley of its respective
               business and the operation of the properties or other assets
               owned or leased by it does not violate or infringe any domestic
               laws, statutes, ordinances, rules or regulations or, to the
               knowledge of VRB and Valley, any foreign laws, statutes,
               ordinances, rules or regulations, the enforcement of which,
               individually or in the aggregate, would have a material adverse
               effect on either VRB or Valley, its business, properties or
               financial condition. Specifically, but without limitations, each
               of VRB and Valley is in compliance in all material respects with
               every local, state or federal law or ordinance, and any
               regulation or order issued thereunder, now in effect and
               applicable to it governing or pertaining to fair housing,
               anti-redlining, equal credit opportunity, truth-in-lending, real
               estate settlement procedures, fair credit reporting and every
               other prohibition against unlawful discrimination in residential
               lending, or governing consumer credit, including, but not limited
               to, the Community

               Reinvestment Act, the Consumer Credit Protection Act,
               Truth-in-Lending Act, and Regulation Z promulgated by the FRB,
               and the Real Estate Settlement Procedures Act of 1974. All loans,
               leases, contracts and accounts receivable (billed and unbilled),
               security agreements, guarantees and recourse agreements, of
               either VRB or Valley, as held in its portfolios, or as sold with
               recourse into the secondary market represent and are valid and
               binding obligations of their respective parties and debtors,
               enforceable in accordance with their respective terms; each of
               them is based on a valid, binding and enforceable contract or
               commitment, each of which has been executed and delivered in full
               compliance, in form and substance, with any and all federal,
               state or local laws applicable to VRB, or to the other party or
               parties to the contract(s) or commitment(s), including without
               limitation the Truth-in-Lending Act, Regulations Z and U of the
               FRB, laws and regulations providing for nondiscriminatory
               practices in the granting of loans or credit, applicable usury
               laws, and laws imposing lending limits; and all such contracts or
               commitments have been administered in full compliance with all
               applicable federal, state or local laws or regulations. All
               Uniform Commercial Code filings, or filings of trust deeds, or of
               liens or other security interest documentation that are required
               by any applicable federal, state or local government laws and
               regulations to perfect the security interests referred to in any
               and all of such documents or other security agreements have been
               made, and all security interests under such deeds, documents or
               security agreements have been perfected, and all contracts have
               been entered into or assumed in full compliance with all
               applicable material legal or regulatory requirements.

               (b) All loan files of Valley are complete and accurate in all
               material respects and have been maintained in accordance with
               good banking practice.

               (c) All notices of default, foreclosure proceedings or
               repossession proceedings against any real or personal property
               collateral have been issued, initiated and conducted by VRB or
               Valley in material formal and substantive compliance with all
               applicable federal, state or local laws and regulations, and no
               loss or impairment of any security interest, or exposure to
               meritorious lawsuits or other proceedings against VRB or Valley
               has been or will be suffered or incurred by VRB or Valley.

               (d) Neither VRB nor Valley is in material violation of any
               applicable servicer or any other requirements of the FHA, VA,
               FNMA, GNMA, FHLMC, SBA or any private mortgage insurer which
               insured or guaranteed any loans owned by VRB or Valley or as to
               which either has sold to other investors, the effect of which
               violation would materially and adversely affect the business,
               assets, earnings, operation or condition (financial or otherwise)
               of VRB or Valley, and with respect to such loans VRB or Valley
               has not done or failed to do, or caused to be done or omitted to
               be done, any act the effect of which act or omission impairs or
               invalidates (i) any FHA insurance or commitments of the FHA to
               insure, (ii) any VA guarantee or commitment of the VA to
               guarantee, (iii) any SBA guarantees or commitments of the SBA to
               guarantee, (iv) any private mortgage insurance or commitment of
               any private mortgage insurer to insure, (v) any title insurance
               policy, (vi) any hazard

                                     App-9

               insurance policy, or (vii) any flood insurance policy required by
               the National Flood Insurance Act of 1968, as amended, which would
               materially and adversely affect the business, assets, earnings,
               operation or condition (financial or otherwise) of VRB or Valley.

               (e) Neither VRB nor Valley have knowingly engaged principally, or
               as one of its important activities, in the business of extending
               credit for the purpose of purchasing or carrying any margin
               stock.

        4.10.  Commitments. Schedule 4.10 is a listing of all outstanding
               commitments, including outstanding letters of credit, repurchase
               agreements and unfunded agreements to lend of Valley.

        4.11.  Hazardous Wastes. To the knowledge of the directors and officers
               of VRB and Valley, neither VRB nor Valley, or any other person
               having an interest in any property which VRB or Valley owns or
               leases, or has owned or leased, or in which either holds any
               security interest, mortgage, or other liens or interest including
               but not limited to as beneficiary of a trust deed ("Property")
               has engaged in the generation, use, manufacture, treatment,
               transportation, storage (in tanks or otherwise), or disposal of
               Hazardous Material on or from such Property. Individually or in
               the aggregate, there has been no: (i) presence, use, generation,
               handling, treatment, storage, release, threatened release,
               migration or disposal of Hazardous Material; (ii) condition that
               could result in any use, ownership or transfer restriction; or
               (iii) condition of nuisance on or from such Property, any of
               which individually or collectively would have a material adverse
               effect on the business, assets, earnings, operation or condition
               (financial or otherwise) of VRB. VRB has received no notice of,
               or has no reason to know of, a condition that could give rise to
               any private or governmental suit, claim, action, proceeding or
               investigation against VRB, Valley, any such other person or such
               Property as a result of any of the foregoing events. "Hazardous
               Material" means any chemical, substance, material, object,
               condition, or waste harmful to human health or safety or to the
               environment due to its radioactivity, ignitability, corrosivity,
               reactivity, explosivity, toxicity, carcinogenicity,
               infectiousness or other harmful or potentially harmful properties
               or effects, including, without limitation, petroleum or petroleum
               products, and all of those chemicals, substances, materials,
               objects, conditions, wastes or combinations of them which are now
               or become listed, defined or regulated in any manner by any
               federal, state or local law based, directly or indirectly, upon
               such properties or effects.

               contingent and other liabilities not set forth in other
               schedules, and includes copies of documents evidencing those
               liabilities. Except as set forth in any schedules to this
               Agreement, and except for FDIC insured deposits and federal funds
               purchased and securities sold under agreements to repurchase
               arising out of transactions subsequent to the date of the latest
               balance sheet filed as with a VRB Public Report, VRB and Valley
               have no obligations or liabilities of any nature (whether
               accrued, absolute,

                                     App-10
<PAGE>   177

               contingent or otherwise) which are material or which, when
               combined with all other such obligations or liabilities would be
               material to the business, assets, earnings, operation or
               condition (financial or otherwise) of VRB or Valley.

        4.13.  No Adverse Changes. Except as set forth in Schedule 4.13, since
               March 31, 2000, (a) there has been no material adverse change in
               the business, assets, earnings, operation or condition (financial
               or otherwise) of VRB; (b) no cash, stock or other dividends, or
               other distributions with respect to capital stock, have been
               declared or paid by VRB, nor has VRB purchased or redeemed any of
               its shares; and (c) there has not been any damage, destruction or
               loss (whether or not covered by insurance) materially and
               adversely affecting any asset material to VRB. As of the
               Effective Date, VRB will have no obligations or liabilities of
               any nature, whether absolute, accrued, contingent or otherwise,
               in excess of $50,000 individually, or $150,000 in the aggregate,
               other than:

               (a) Obligations and liabilities disclosed in VRB Public Reports
               as of March 31, 2000, or in the schedules provided herewith;

               (b) Obligations and liabilities incurred in, or as a result of,
               the normal and ordinary course of business, consistent with past
               practices, which do not, in the aggregate, have a material
               adverse effect on the business, assets, earnings, operation or
               condition (financial or otherwise) of VRB; and

               (c) Obligations and liabilities incurred otherwise than in or as
               a result of the normal and ordinary course of business consistent
               with past practices, provided Umpqua shall have consented
               thereto.

               To the best knowledge of VRB, there is no basis for any claim
               against VRB or any other obligation or liability of any nature,
               in excess of $50,000 individually or $150,000 in the aggregate.

        4.14.  Regulatory Approvals Required. The nature of the business and
               operations of VRB does not require any approval, authorization,
               consent, license, clearance or order of, any declaration or
               notification to, or any filing or registration with, any
               governmental or regulatory authority in order to permit VRB to
               perform its obligations under this Agreement, or to prevent the
               termination of any material right, privilege, license or
               agreement of VRB, or any material loss or disadvantage to its
               business, upon consummation of the Holding Company Plan of Merger
               or Bank Plan of Merger, except for:

               (a) Approval of the Bank Plan of Merger by the Oregon Director
               and the FDIC;

               (b) Approval from, or waiver of jurisdiction by, the FRB of the
               Holding Company Merger;

<PAGE>   178

               (c) Filing of the Holding Company Plan of Merger and Articles of
               Merger with the Oregon Secretary of State;

               (d) Participation along with Umpqua in a fairness hearing before
               the Oregon Director relating to the Oregon Director's approval of
               the transactions contemplated hereby; and

               (e) Filing with the SEC of the definitive Joint Proxy Statement
               in accordance with the Exchange Act rules governing proxy
               solicitations.

        4.15.  Corporate and Shareholder Approval of Agreement, Binding
               Obligations. VRB and Valley each has all requisite corporate
               power to execute, deliver and perform its obligations under this
               Agreement. The execution, delivery and performance of this
               Agreement, and the transactions contemplated thereby, have been
               duly authorized by the Board of Directors of each of VRB and
               Valley. No other corporate action on the part of VRB or Valley
               other than shareholder approval is required to authorize this
               Agreement or the Holding Company Plan of Merger or Bank Plan of
               Merger or the consummation of the transactions contemplated
               thereby. This Agreement has been duly executed and delivered by
               VRB and Valley and constitutes the legal, valid and binding
               obligation of each of them enforceable in accordance with its
               terms. The Holding Company Plan of Merger and Bank Plan of
               Merger, when duly executed and delivered by VRB or Valley, as the
               case may be, will constitute the legal, valid and binding
               obligations of VRB and Valley, as the case may be, enforceable in
               accordance with their terms.

        4.16.  No Defaults from Transaction. Subject to compliance with the
               governmental approvals described in Section 4.14, neither the
               execution, delivery and performance of this Agreement and the
               Holding Company Plan of Merger or Bank Plan of Merger by VRB and
               Valley, as the case may be, nor the consummation of the
               transactions contemplated thereby will conflict with, result in
               any breach or violation of, or result in any default or any
               acceleration of performance under, any of the terms, conditions
               or provisions of the Articles of Incorporation or Bylaws of
               either VRB or Valley, or (assuming the accuracy of Umpqua's and
               Surviving Bank's representations and warranties, compliance with
               their covenants, and the performance of their obligations under
               this Agreement and the Holding Company Plan of Merger and Bank
               Plan of Merger) of any statute, regulation or existing order,
               writ, injunction or decree of any court or governmental agency,
               or of any contract, agreement or instrument to which either is a
               party or by which either is bound, or will result in the
               declaration or imposition of any lien, charge or encumbrance upon
               any of the assets of VRB or Valley which are material to their
               business. Assuming the accuracy of Umpqua's and Surviving Bank's
               representations and warranties, compliance with their covenants,
               and the performance of their obligations under this Agreement and
               the Holding Company Plan of Merger and Bank Plan of Merger, the
               consummation of the transactions contemplated by this Agreement
               will not result in any material adverse change in


                                     App-12

               the business, assets, earnings, operations or conditions
               (financial or otherwise) of VRB or Valley.

        4.17.  Tax Returns. VRB has filed all federal, state and other income,
               franchise or other tax returns, required to be filed by it; each
               such return is complete and accurate in all material respects;
               and all taxes and related interest and liabilities to be paid in
               connection therewith have been paid or adequate reserve has been
               established for the timely payment thereof. VRB and Valley have
               timely and accurately filed all currency transaction reports
               required by the Bank Secrecy Act, as amended, and has timely and
               accurately filed all required information returns and reports,
               including without limitation forms 1099, and has exercised due
               diligence in obtaining certified taxpayer identification numbers
               as required by the Code and Treasury Regulations. VRB has not
               received notice of any federal, state or other income, franchise
               or other tax assessment or notice of a deficiency to date which
               has not been paid or for which adequate reserve has not been
               provided, and VRB does not know of any pending or threatened
               audit or investigation of VRB with respect to any tax
               liabilities. There are currently no agreements in effect with
               respect to VRB to extend the period of limitations for assessment
               or collection of any tax. Schedule 4.17 includes copies of VRB's
               federal and state tax returns for years 1997 through 1999.

        4.18.  Real Property, Leased Personal Property. Schedule 4.18 is a list
               setting forth all real property owned by VRB or Valley as
               present, former or future bank premises and all real property
               currently held as other real estate owned. Except as set forth in
               that Schedule or except for disposition of other real estate
               owned in the ordinary course of business, VRB or Valley will own
               all of such real property, presently owned, on the Effective
               Date. Except as may be noted on that Schedule, all real property
               reflected in the VRB Public Reports as of March 31, 2000 is
               included in that Schedule. The leases pursuant to which VRB or
               Valley leases real and personal property, copies of which have
               also been delivered to Umpqua as part of Schedule 4.18, are valid
               and effective in accordance with their respective terms and there
               is not under any such lease any default nor has there occurred
               any event which, with the giving of notice, lapse of time, or
               otherwise, would constitute an event of default. Except as
               disclosed in Schedule 4.18 or arising pursuant to the leases
               relating thereto, the real and personal property leased by VRB or
               Valley is free of any adverse claims. Except as noted on Schedule
               4.18, all buildings and structures on the real property, the
               equipment located thereon, and the real and personal property
               leased by VRB or Valley, are in all material respects in good
               operating condition and repair and conform in all material
               respects to all applicable laws, ordinances and regulations.
               Except as disclosed in Schedule 4.18 or arising pursuant to the
               leases relating thereto, VRB and Valley have good and marketable
               title to all of their real and personal property, subject to no
               mortgages, pledges, encumbrances, liens or charges of any kind,
               except liens for taxes not delinquent. VRB and Valley owns or
               leases all property on which their continued business operations
               are materially dependent.

        4.19.  Insurance. Except as set forth in Schedule 4.19, for each of the
               past six years and continuing to date, VRB has insured its
               business and real and personal property against all risks of a
               character usually insured against by banks, including but not
               limited to financial institution bond, directors and officers
               liability, property and casualty and commercial liability
               insurance, with customary amounts of coverage, deductibles and
               exclusions by reputable insurers authorized to transact insurance
               in the State of Oregon and such other jurisdictions where it
               operates or owns property, and it will maintain all existing
               insurance through the Effective Date. VRB is in compliance with
               all existing insurance policies and has not failed to give timely
               notice of, or present properly, any material claim thereunder.
               Schedule 4.19 includes copies of all insurance policies currently
               in force with respect to VRB's business and real and personal
               property.

        4.20.  Trademarks. VRB owns or has valid licenses to use all patents,
               trademarks, copyrights or trade names which it considers to be
               material to its business taken as a whole, and has not been
               charged with infringement or violation of any patent, trademark,
               copyright or trade name which would be likely to have a material
               adverse effect on its business.

        4.21.  Contracts and Agreements. Schedule 4.21 includes copies of all
               material outstanding contracts, agreements, leases or
               understandings to which VRB or Valley is a party or to which any
               of its properties are subject except for any contracts or
               agreements entered into with its customers in the ordinary course
               of business. Such documents include, without limitation, all
               agreements, contracts, leases or understandings with officers and
               directors of VRB, all of which are related to, and have been
               entered into in the ordinary course of VRB's banking business.
               VRB is not in material default or breach, and there has not
               occurred any event which with notice or lapse of time would
               constitute a material breach or default, under any contract,
               agreement, instrument, lease or understanding, and, excluding any
               loan agreements or notices with VRB customers reflected in VRB's
               regular delinquent loan reports which have been and will be made
               available to Umpqua, VRB does not know of any default by any
               other party thereto; and no contract, agreement, lease or
               undertaking referred to in this Section 4.21, or in such other
               schedules will be modified or changed prior to the Effective Date
               without the prior written consent of Umpqua. No consent or
               approval by the parties thereto is required by reason of this
               Agreement to maintain such contracts, agreements, leases and
               undertakings in effect. No waiver or indulgence has been granted
               by any of the landlords under any such leases.

        4.22.  Employee Benefits.

               (a) Each Employee Benefit Plan sponsored or maintained by VRB or
               any affiliate of VRB as determined under Section 414(b), (c), (m)
               or (o) of the Code ("ERISA Affiliate") is set forth in Schedule
               4.22. Except as set forth in such Schedule, neither VRB nor any
               ERISA Affiliate maintains nor has sponsored any other pension,
               profit sharing, thrift, savings, bonus, retirement, vacation,
               life insurance,

                                     App-14
<PAGE>   181

               health insurance, severance, sickness, disability, medical or
               death benefit plans, whether or not subject to ERISA.

               Except as set forth on Schedule 4.22, there are no employment
               contracts entered into by VRB or Valley and no other deferred
               compensation contracts, agreements, arrangements or commitments
               maintained or agreed to by it that provides for or could result
               in the payment to any VRB or Valley employee or former employee
               of any money or other property rights or accelerate the vesting
               or payment of such amounts or rights to any employee as a result
               of the transactions contemplated herein, whether or not such
               payment or acceleration would constitute a parachute payment
               within the meaning of Code Section 280G. There are no other
               compensation, employment or collective bargaining agreements,
               stock options, stock purchase agreements, life, health, accident
               or other insurance, bonus, deferred or incentive compensation,
               change-in-control, severance or separation, profit sharing,
               retirement, or other employee fringe benefit policies or
               arrangements of any kind that could result in the payment to any
               employees or former employees or other persons of VRB or Valley
               of any money or other property.

               (b) The only "employee welfare benefit plans" (as defined in
               Section 3(1) of ERISA) sponsored or maintained by VRB or any
               ERISA Affiliate, or to which VRB or any ERISA Affiliate
               contributes ("Welfare Benefit Plan") or are required to
               contribute, are as set forth in Schedule 4.22. Schedule 4.22
               includes the amount of liability of VRB for payments more than
               thirty days past due with respect to such Welfare Benefit Plans
               as of December 31, 1999, the amount of monthly payments due and
               owing for each month that such plans are continued, and the
               amount of liability for claims if VRB were to terminate such
               plans and the costs involved in any such termination. Each
               Welfare Benefit Plan which is a group health plan (within the
               meaning of Section 5000(b)(1) of the Code) complies with and has
               been maintained and operated in accordance with each of the
               requirements of Section 4980B of the Code and Part 6 of the
               Subtitle B of Title I of ERISA. Schedule 4.22 sets forth the
               individuals with rights to continuation coverage under Section
               4980B of the Code or Part 6 of Subtitle B of title I of ERISA or
               state law, including those individuals within the applicable
               election period.

               (c) Other than as set forth in Schedule 4.22, VRB or any ERISA
               Affiliate has not maintained a pension benefit plan that is
               subject to title 1, subtitle B, part 3 of ERISA ("Pension Benefit
               Plan"). With respect to any such Pension Benefit Plan, the amount
               of liability for any contribution paid or owing with respect to
               such Pension Benefit Plan for the last or current plan year and
               the plan year in which the Effective Date occurs are set forth on
               Schedule 4.22. There are no other material liabilities that would
               be incurred in connection with a termination of the Plan, and the
               Plan is fully funded.

               (d) VRB and, to the knowledge of the executive officers and
               directors of VRB, all persons having fiduciary or other
               responsibilities or duties with respect to any Employee Benefit
               Plan, are, and have since inception been, in compliance in all

                                     App-15
<PAGE>   182

               material respects with, and each such Employee Benefit Plan is
               and has been operated in accordance with, its provisions and in
               compliance with the applicable laws, rules and regulations
               governing such Plan, including, without limitation, the rules and
               regulations promulgated by the Department of Labor, the Pension
               Benefit Guaranty Corporation and the Internal Revenue Service
               under ERISA or the Code. Each Pension Benefit Plan and any
               related trust agreements or annuity contracts (or any other
               funding instruments) comply currently, and have complied in the
               past, both as to form and operation, with the provisions of ERISA
               and the Code (including Section 410(b) of the Code relating to
               coverage), where required in order to be tax-qualified under
               Section 401(a) or 403(a) or other applicable provisions of the
               Code, and all other applicable laws, rules and regulations; all
               necessary governmental approvals for the Employee Benefit Plans
               have been obtained; and a favorable determination as to the
               qualification under the Code of each Pension Benefit Plan set
               forth in Schedule 4.22 and each amendment thereto has been made
               by the Internal Revenue Service. No Plan is a "multi-employer
               pension plan," as such term is defined in Section 3(37) of ERISA.
               To the best knowledge of VRB, all contributions or other amounts
               payable by VRB as of the Effective Date with respect to each Plan
               in respect of current or prior plan years have been paid or
               accrued in accordance with GAAP and Section 412 of the Code, and
               there are no pending, threatened or anticipated claims (other
               than routine claims for benefits) by, on behalf of or against any
               of the Plans or any trusts related thereto which would,
               individually or in the aggregate, have or be reasonably expected
               to have a material adverse effect on VRB.

               (e) Each Welfare Benefit Plan and each Pension Benefit Plan has
               been administered to date in material compliance with the
               requirements of the claims procedure of the Code and ERISA. All
               reports required by any government agency and disclosures to
               participants with respect to each Welfare Benefit Plan and each
               Pension Benefit Plan have been timely made or filed. Each
               Employee Benefit Plan has been operated since inception in
               material compliance with the governing instruments and applicable
               federal or state law. In particular, but without limitation, each
               Welfare Benefit Plan has been administered in material compliance
               with federal law, including without limitation the health care
               continuation requirements of federal law ("COBRA"). No Employee
               Benefit Plan provides benefits, including without limitation
               death or medical benefits (whether or not insured), with respect
               to current or former employees of VRB or any ERISA Affiliate
               beyond their retirement or other termination of service, other
               than (i) coverage mandated by applicable law, (ii) death benefits
               or retirement benefits under any "employee pension plan," as that
               term is defined in Section 3(2) of ERISA, (iii) any deferred
               compensation benefits accrued as liabilities on the books of VRB
               or any ERISA Affiliates or (iv) benefits the full cost of which
               is borne by the current or former employee (or his beneficiary).

               (f) Neither VRB nor, to its knowledge, any plan fiduciary of any
               Welfare Benefit Plan or Pension Benefit Plan, has engaged in any
               transaction in violation of Section 406(a) or (b) of ERISA (for
               which no exemption exists under Section 408 of

                                     App-16
<PAGE>   183

               ERISA) or any "prohibited transaction" (as defined in Section
               4975(c)(1) of the Code) for which no exemption exists under
               Section 4975(c)(2) or (d) of the Code or in any prohibited
               transactions under predecessor provisions of the Code. To the
               best knowledge of VRB, neither VRB nor any ERISA Affiliate has
               engaged in a transaction in connection with which VRB or any
               ERISA Affiliate could be subject to either a material civil
               penalty assessed pursuant to Section 409 or 502(i) of ERISA or a
               material tax imposed pursuant to Section 4975 or 4976 of the
               Code.

               (g) VRB has had no liability to the Pension Benefit Guaranty
               Corporation ("PBGC"). No material liability to the PBGC has been
               or will be incurred by VRB or other trade or business under
               "common control" with VRB (as determined under Section 414(c),
               (b), (m) or (o) of the Code) on account of any termination of an
               employee pension benefit plan subject to title IV of ERISA.
               Except as set forth in Schedule 4.22, since September 1, 1974, no
               filing has been made by VRB (or any ERISA Affiliate) with the

               of ERISA maintained, or wholly or partially funded by VRB (or any
               ERISA Affiliate). Neither VRB nor any ERISA Affiliate has (i)

               provisions of Section 4062(e) of ERISA, (ii) withdrawn as a

               before the Effective Date to any employee pension benefit plan
               subject to Section 4064(a) of ERISA to which VRB (or any ERISA
               Affiliate) made contributions during the five years prior to the
               Effective Date, or (iv) made a complete or partial withdrawal
               from a multi-employer plan (as defined in Section 3(37) of ERISA)
               so as to incur withdrawal liability as defined in Section 4201 of
               ERISA (without regard to subsequent reduction or waiver of such
               liability under Section 4207 or 4208 or ERISA).

               (h) Complete and correct copies of the following documents have
               been furnished to Umpqua as Schedule 4.22:

                   (i) Each Employee Benefit Plan and any related trust
               agreements;

                                     App-17

                   (vi) Any actuarial reports and PBGC Forms 1 for the last 2
               years.

               (i) Each Welfare Benefit Plan and each Pension Benefit Plan is

               are no defaults thereunder.

        4.23.  Employment Disputes. There is no labor strike, dispute, slowdown
               or stoppage pending or, to the best knowledge of VRB, threatened
               against VRB, and VRB does not have any knowledge of any attempt
               to organize any employees of VRB or Valley into a collective
               bargaining unit. Consummation of the Plans of Merger will not
               (either alone or in combination with any other act or event)
               result in any payment of severance pay or any other payment
               becoming due from VRB to any of its employees except as set forth
               in Schedule 4.23. VRB is not a party to any agreement involving
               payments to any person or entity based upon the profits, revenues
               or other financial performance of VRB except as set forth on
               Schedule 4.23.

        4.24.  Reserve for Loan Losses. VRB's reserve for loan losses, as
               established from time to time, is adequate as determined by the
               standards applied to VRB and Valley by the applicable bank
               regulatory agencies and pursuant to generally accepted accounting
               principles. Since March 31, 2000, VRB has not and prior to the
               Effective Date shall not, reverse any provision taken for loan
               losses.

        4.25.  Repurchase Agreement. VRB has valid and perfected first position
               security interests in all government securities subject to
               repurchase agreements and the market value of the collateral
               securing each such repurchase agreement equals or exceeds the
               amount of the debt secured by such collateral under such
               agreement.

        4.26.  Shareholder List. The list of shareholders of VRB dated July 14,
               2000, provided to Umpqua as Schedule 4.26, is a true, correct and
               complete list of the names, addresses and holdings of all record
               holders of VRB Common Stock as of that date. Based on information
               made available to VRB and on filings with the SEC pursuant to
               Sections 13(d) and 16(a) of the Exchange Act, VRB shall notify
               Umpqua of any change in such stock ownership of over one percent
               (1%) through the Effective Date.

        4.27.  Proxy Statement. The registration statement to be filed by Umpqua
               with the Oregon Director and the proxy statement to be used by
               VRB to solicit proxies from the holders of VRB Common Stock for
               the meeting of shareholders held to consider and vote upon this
               Agreement and the Holding Company Plan of Merger, and the
               transactions contemplated thereby (in its definitive form, the
               "Proxy Statement"), will fairly describe the transaction and VRB,
               and will contain no untrue statement of any material fact and
               will not omit to state any material fact required to be stated
               therein or necessary to make the statements therein not
               misleading, except those

                                     App-18
<PAGE>   185

               statements in or omission from the Proxy Statement which may be
               made with respect to Umpqua. VRB will promptly advise Umpqua in
               writing if at any time prior to the Effective Date VRB shall
               obtain knowledge of any facts that might make it necessary or
               appropriate to amend or supplement the Proxy Statement in order
               to make the statements therein not misleading or to comply with
               applicable law.

        4.28.  Interests of Directors and Others. Except as disclosed in any VRB
               Public Reports, no officer or director of VRB or Valley has any
               material interest in any assets or property (whether real or
               personal, tangible or intangible), of or used in the business of
               VRB or Valley other than as an owner of outstanding securities or
               deposit accounts of VRB or Valley, or as borrowers under loans
               fully performing in accordance with their terms, which terms are
               no more favorable than those available to unaffiliated parties
               made at or about the same time.

        4.29.  Schedules to this Agreement. The information contained in each
               schedule to this Agreement prepared by or on behalf of VRB
               constitutes additional representations and warranties made by VRB
               hereunder and is incorporated herein by reference. The copies of
               documents furnished as part of these schedules are true, correct
               and complete copies and include all amendments, supplements, and
               modifications thereto and all express waivers applicable
               thereunder.

        4.30.  No Misstatements or Omissions. No representation or warranty of
               VRB or Valley in this Agreement or in any statement, certificate
               or schedule furnished or to be furnished by VRB pursuant to this
               Agreement or in connection with the transaction contemplated by
               this Agreement, contains or will contain any untrue statements of
               a material fact or omits or will omit to state any material fact.

               standing in every jurisdiction in which such qualification is
               required except where the failure to so qualify would not result
               in any material adverse effect on its business operation,
               financial condition or properties.


                                     App-19

               no subscriptions, options, warrants, convertible securities or
               other rights or commitments which would enable the holder to
               acquire any shares of capital stock or other investment
               securities of Umpqua, or which enable or require Umpqua to
               acquire shares of its capital stock or other investment

               the Effective Date, Umpqua will file with the SEC (and will

               reports and other documents which Umpqua is required by the

               Bank is in violation of any provision of its Articles of

               Umpqua nor Surviving Bank, directly or indirectly, owns or
               controls, either by power to control the investment or power to

               course of business and shares representing less than five percent
               of the outstanding shares of such corporation acquired in partial
               or full satisfaction of debts previously contracted. Neither
               Umpqua nor any of its Subsidiaries is a part of any joint
               venture, or general or limited partnership, or a member of any
               unincorporated association.

               statements and notices of shareholder meetings, to the extent
               such reports and communications have not been filed with any

               days such materials are first sent to its shareholders.

        5.7.   Books and Records. The books and records of Umpqua and its

               transactions to which it is a party or by which it or its
               properties are bound or subject. Such books and records have been
               and are accurate and complete and comply in all material respects
               with applicable legal, regulatory and accounting requirements.

        5.8.   Legal Proceedings. Except for regulatory examinations conducted

               officer or agency, other governmental body or arbitration which
               might, individually or in the aggregate, result in any material
               adverse change in the business, assets, earnings, operation or
               condition (financial or otherwise) of Umpqua or which might
               hinder or delay the consummation of the transactions contemplated
               by this Agreement.

        5.9.   Compliance with Lending Laws and Regulations. Except as disclosed

               respective business and the operation of the properties or other
               assets owned or leased by it does not violate or infringe any
               domestic laws, statutes, ordinances, rules or regulations, or to

               (c) All notices of default, foreclosure proceedings or
               repossession proceedings against any real or personal property
               collateral have been issued, initiated and conducted by Umpqua or
               Surviving Bank in material formal and substantive compliance with
               all applicable federal, state or local laws and regulations, and
               no loss or impairment of any security interest, or exposure to
               meritorious lawsuits or other proceedings against Umpqua or
               Surviving Bank has been or will be suffered or incurred by Umpqua
               or Surviving Bank.

               (d) Neither Umpqua nor Surviving Bank is in material violation of
               any applicable servicer or any other requirements of the FHA, VA,
               FNMA, GNMA, FHLMC, SBA or any private mortgage insurer which
               insured or guaranteed any loans owned by Umpqua or Surviving Bank
               or as to which either has sold to other investors, the effect of
               which violation would materially and adversely affect the
               business, assets, earnings, operation or condition (financial or
               otherwise) of Umpqua or Surviving

               Bank, and with respect to such loans Umpqua or Surviving Bank has
               not done or failed to do, or caused to be done or omitted to be
               done, any act the effect of which act or omission impairs or
               invalidates (i) any FHA insurance or commitments of the FHA to
               insure, (ii) any VA guarantee or commitment of the VA to
               guarantee, (iii) any SBA guarantees or commitments of the SBA to
               guarantee, (iv) any private mortgage insurance or commitment of
               any private mortgage insurer to insure, (v) any title insurance
               policy, (vi) any hazard insurance policy, or (vii) any flood
               insurance policy required by the National Flood Insurance Act of
               1968, as amended, which would materially and adversely affect the
               business, assets, earnings, operation or condition (financial or
               otherwise) of Umpqua or Surviving Bank.

               (e) Neither Umpqua nor its Subsidiaries (except through its
               registered broker dealer Subsidiary) have knowingly engaged
               principally, or as one of its important activities, in the
               business of extending credit for the purpose of purchasing or
               carrying any margin stock.

        5.10.  Commitments. Schedule 5.10 is a listing of all outstanding
               commitments, including outstanding letters of credit, repurchase
               agreements and unfunded agreements to lend of Surviving Bank.

        5.11.  Hazardous Wastes. To the knowledge of the directors and officers
               of Umpqua and Surviving Bank, neither Umpqua nor its
               Subsidiaries, or any other person having an interest in any
               property which Umpqua or its Subsidiaries owns or leases, or has
               owned or leased, or in which either holds any security interest,
               mortgage, or other liens or interest including but not limited to
               as beneficiary of a trust deed ("Property") has engaged in the
               generation, use, manufacture, treatment, transportation, storage
               (in tanks or otherwise), or disposal of Hazardous Material on or
               from such Property. Individually or in the aggregate, there has
               been no: (i) presence, use, generation, handling, treatment,
               storage, release, threatened release, migration or disposal of
               Hazardous Material; (ii) condition that could result in any use,
               ownership or transfer restriction; or (iii) condition of nuisance
               on or from such Property, any of which individually or
               collectively would have a material adverse effect on the
               business, assets, earnings, operation or condition (financial or
               otherwise) of Umpqua. Umpqua has received no notice of, or has no
               reason to know of, a condition that could give rise to any
               private or governmental suit, claim, action, proceeding or
               investigation against Umpqua, any Subsidiary of Umpqua, any such
               other Person, or such Property as a result of any of the
               foregoing events. "Hazardous Material" means any chemical,
               substance, material, object, condition, or waste harmful to human
               health or safety or to the environment due to its radioactivity,
               ignitability, corrosivity, reactivity, explosivity, toxicity,
               carcinogenicity, infectiousness or other harmful or potentially
               harmful properties or effects, including, without limitation,
               petroleum or petroleum products, and all of those chemicals,
               substances, materials, objects, conditions, wastes or
               combinations of them which are now or become listed, defined or
               regulated in any manner by any

               federal, state or local law based, directly or indirectly, upon
               such properties or effects.

        5.12.  Contingent and Other Liabilities. Schedule 5.12 is a list of
               contingent and other liabilities not set forth in other
               schedules, and includes copies of documents evidencing those
               liabilities. Except as set forth in any schedules to this
               Agreement, and except for FDIC insured deposits and federal funds
               purchased and securities sold under agreements to repurchase
               arising out of transactions subsequent to the date of the latest
               balance sheet filed as with a Umpqua Public Reports, Umpqua and
               its Subsidiaries have no obligations or liabilities of any nature
               (whether accrued, absolute, contingent or otherwise) which are
               material or which, when combined with all other such obligations
               or liabilities would be material to the business, assets,
               earnings, operation or condition (financial or otherwise) of
               Umpqua or Surviving Bank.

        5.13.  No Adverse Changes. Except as set forth in Schedule 5.13, since
               March 31, 2000, (a) there has been no material adverse change in
               the business, assets, earnings, operation or condition (financial
               or otherwise) of Umpqua; (b) no cash, stock or other dividends,
               or other distributions with respect to capital stock, have been
               declared or paid by Umpqua, nor has Umpqua purchased or redeemed
               any of its shares; and (c) there has not been any damage,
               destruction or loss (whether or not covered by insurance)
               materially and adversely affecting any asset material to Umpqua.
               As of the Effective Date, Umpqua will have no obligations or
               liabilities of any nature, whether absolute, accrued, contingent
               or otherwise, in excess of $50,000 individually, or $150,000 in
               the aggregate, other than:

               (a) Obligations and liabilities disclosed in Umpqua Public
               Reports as of March 31, 2000, or schedules provided herewith;

               (b) Obligations and liabilities incurred in, or as a result of,
               the normal and ordinary course of business, consistent with past
               practices, which do not, in the aggregate, have a material
               adverse effect on the business, assets, earnings, operation or
               condition (financial or otherwise) of Umpqua; and

               (c) Obligations and liabilities incurred otherwise than in or as
               a result of the normal and ordinary course of business consistent
               with past practices, provided Umpqua shall have consented
               thereto.

               To the best knowledge of Umpqua, there is no basis for any claim
               against Umpqua or any other obligation or liability of any
               nature, in excess of $50,000 individually or $150,000 in the
               aggregate.

        5.14.  Regulatory Approvals Required. The nature of the business and
               operations of Umpqua does not require any approval,
               authorization, consent, license, clearance or order of, any
               declaration or notification to, or any filing or registration
               with, any governmental or regulatory authority in order to permit
               Umpqua to perform its

               of any material right, privilege, license or agreement of Umpqua,
               or any material loss or disadvantage to its business, upon
               consummation of the Holding Company Plan of Merger or Bank Plan
               of Merger, except for:

        5.15.  Corporate and Shareholder Approval of Agreement, Binding
               Obligations. Umpqua and Surviving Bank each has all requisite
               corporate power to execute, deliver and perform its obligations
               under this Agreement. The execution, delivery and performance of
               this Agreement, and the transactions contemplated thereby, have
               been duly authorized by the Board of Directors of each of Umpqua
               and Surviving Bank. No other corporate action on the part of
               Umpqua or Surviving Bank other than shareholder approval is
               required to authorize this Agreement or the Holding Company Plan
               of Merger or Bank Plan of Merger or the consummation of the
               transactions contemplated thereby. This Agreement has been duly

               them enforceable in accordance with its terms. The Holding

               may be, will constitute the legal, valid and binding obligations
               of Umpqua and Surviving Bank, as the case may be, enforceable in
               accordance with their terms.

                                     App-25
<PAGE>   192

               Plan of Merger by Umpqua and Surviving Bank, as the case may be,
               nor the consummation of the transactions contemplated thereby
               will conflict with, result in any breach or violation of, or
               result in any default or any acceleration of performance under,
               any of the terms, conditions or provisions of the Articles of
               Incorporation or Bylaws of either Umpqua or Surviving Bank, or
               (assuming the accuracy of VRB and Valley's representations and
               warranties, compliance with their covenants, and the performance
               of their obligations under this Agreement and the Holding Company
               Plan of Merger and the Bank Plan of Merger) of any statute,
               regulation or existing order, writ, injunction or decree of any
               court or governmental agency, or of any contract, agreement or
               instrument to which either is a party or by which either is
               bound, or will result in the declaration or imposition of any
               lien, charge or encumbrance upon any of the assets of Umpqua or
               its Subsidiaries which are material to the business of Umpqua or
               Surviving Bank. Assuming the accuracy of Umpqua's and Surviving
               Bank's representations and warranties, compliance with their
               covenants, and the performance of their obligations under this
               Agreement and the Holding Company Plan of Merger and Bank Plan of
               Merger, the consummation of the transactions contemplated by this
               Agreement will not result in any material adverse change in the
               business, assets, earnings, operations or conditions (financial
               or otherwise) of Umpqua or Surviving Bank.

        5.17.  Tax Returns. Umpqua has filed all federal, state and other
               income, franchise or other tax returns, required to be filed by
               it; each such return is complete and accurate in all material
               respects; and all taxes and related interest and liabilities to
               be paid in connection therewith have been paid or adequate
               reserve has been established for the timely payment thereof.
               Umpqua and Surviving Bank have timely and accurately filed all
               currency transaction reports required by the Bank Secrecy Act, as
               amended, and has timely and accurately filed all required
               information returns and reports, including without limitation
               forms 1099, and has exercised due diligence in obtaining
               certified taxpayer identification numbers as required by the Code
               and Treasury Regulations. Umpqua has not received notice of any
               federal, state or other income, franchise or other tax assessment
               or notice of a deficiency to date which has not been paid or for
               which adequate reserve has not been provided, and Umpqua does not
               know of any pending or threatened audit or investigation of
               Umpqua with respect to any tax liabilities. There are currently
               no agreements in effect with respect to Umpqua to extend the
               period of limitations for assessment or collection of any tax.
               Schedule 5.17 includes copies of Umpqua's federal and state tax
               returns for years 1997 through 1999.

        5.18.  Real Property, Leased Personal Property. Schedule 5.18 is a list
               setting forth all real property owned by Umpqua or any of its
               Subsidiaries as present, former or future bank premises and all
               real property currently held as other real estate owned. Except
               as set forth in that Schedule or except for disposition of other
               real estate owned in the ordinary course of business, Umpqua or
               the applicable Subsidiary will own all of such real property,
               presently owned, on the Effective Date. Except as may be noted on
               that Schedule, all real property reflected in the Umpqua Public
               Reports as of March 31, 2000 is included in that Schedule. The
               leases pursuant to

<PAGE>   193

               which Umpqua or the applicable Subsidiary leases real and
               personal property, copies of which have also been delivered to
               VRB as part of Schedule 5.18, are valid and effective in
               accordance with their respective terms and there is not under any
               such lease any default nor has there occurred any event which,
               with the giving of notice, lapse of time, or otherwise, would
               constitute an event of default. Except as disclosed in Schedule
               5.18 or arising pursuant to the leases relating thereto, the real
               and personal property leased by Umpqua and its Subsidiaries is
               free of any adverse claims. Except as noted on Schedule 5.18, all
               buildings and structures on the real property, the equipment
               located thereon, and the real and personal property leased by
               Umpqua or its Subsidiaries, are in all material respects in good
               operating condition and repair and conform in all material
               respects to all applicable laws, ordinances and regulations.
               Except as disclosed in the title reports therefor or arising
               pursuant to the leases relating thereto, Umpqua and its
               Subsidiaries have good and marketable title to all of their real
               and personal property, subject to no mortgages, pledges,
               encumbrances, liens or charges of any kind, except liens for
               taxes not delinquent. Umpqua and its Subsidiaries own or lease
               all property on which their continued business operations are
               materially dependent.

        5.19.  Insurance. Except as set forth in Schedule 5.19, for each of the
               past six years and continuing to date, Umpqua has insured its
               business and real and personal property against all risks of a
               character usually insured against by banks, including but not
               limited to financial institution bond, directors and officers
               liability, property and casualty and commercial liability
               insurance, with customary amounts of coverage, deductibles and
               exclusions by reputable insurers authorized to transact insurance
               in the State of Oregon and such other jurisdictions where it
               operates or owns property, and it will maintain all existing
               insurance through the Effective Date. Umpqua is in compliance
               with all existing insurance policies and has not failed to give
               timely notice of, or present properly, any material claim
               thereunder. Schedule 5.19 includes copies of all insurance
               policies currently in force with respect to Umpqua's business and
               real and personal property.

        5.20.  Trademarks. Umpqua owns or has valid licenses to use all patents,
               trademarks, copyrights or trade names which it considers to be
               material to its business taken as a whole, and have not been
               charged with infringement or violation of any patent, trademark,
               copyright or trade name which would be likely to have a material
               adverse effect on its business.

        5.21.  Contracts and Agreements. Schedule 5.21 includes copies of all
               material outstanding contracts, agreements, leases or
               understandings to which Umpqua or Surviving Bank is a party or to
               which any of its properties are subject except for any contracts
               or agreements entered into with its customers in the ordinary
               course of business. Such documents include, without limitation,
               all agreements, contracts, leases or understandings with officers
               and directors of Umpqua, all of which are related to, and have
               been entered into in the ordinary course of, Umpqua's banking
               business. Umpqua is not in material default or breach, and to the
               knowledge of Umpqua there has not occurred any event which with
               notice or lapse of time would

               constitute a material breach or default, under any contract,
               agreement, instrument, lease or understanding, and, excluding any
               loan agreements or notices with Umpqua customers reflected in
               Umpqua's regular delinquent loan reports which have been and will
               be made available to Umpqua, Umpqua does not know of any default
               by any other party thereto; and no contract, agreement, lease or
               undertaking referred to in this Section 5.21, or in such other
               schedules will be modified or changed prior to the Effective Date
               without the prior written consent of VRB. No consent or approval
               by the parties thereto is required by reason of this Agreement to
               maintain such contracts, agreements, leases and undertakings in
               effect. No waiver or indulgence has been granted by any of the
               landlords under any such leases.

        5.22.  Employee Benefits.

               (a) Each Employee Benefit Plan, sponsored or maintained by Umpqua
               or any affiliate of Umpqua as determined under Section 414(b),
               (c), (m) or (o) of the Code ("ERISA Affiliate") is set forth in
               Schedule 5.22. Except as set forth in such Schedule, neither
               Umpqua nor any ERISA Affiliate maintains nor has sponsored any
               other pension, profit sharing, thrift, savings, bonus,
               retirement, vacation, life insurance, health insurance,
               severance, sickness, disability, medical or death benefit plans,
               whether or not subject to ERISA.

               Except as set forth on Schedule 5.22, there are no employment
               contracts entered into by Umpqua or Surviving Bank and no other
               deferred compensation contracts, agreements, arrangements or
               commitments maintained or agreed to by it that provides for or
               could result in the payment to any Umpqua or Surviving Bank
               employee or former employee of any money or other property rights
               or accelerate the vesting or payment of such amounts or rights to
               any employee as a result of the transactions contemplated herein,
               whether or not such payment or acceleration would constitute a
               parachute payment within the meaning of Code Section 280G. There
               are no other compensation, employment or collective bargaining
               agreements, stock options, stock purchase agreements, life,
               health, accident or other insurance, bonus, deferred or incentive
               compensation, change-in-control, severance or separation, profit
               sharing, retirement, or other employee fringe benefit policies or
               arrangements of any kind that could result in the payment to any
               employees or former employees or other persons of Umpqua or
               Surviving Bank of any money or other property.

               (b) The only "employee welfare benefit plans" (as defined in
               Section 3(1) of ERISA) sponsored or maintained by Umpqua or any
               ERISA Affiliate, or to which Umpqua or any ERISA Affiliate
               contributes ("Welfare Benefit Plan") or are required to
               contribute, are as set forth in Schedule 5.22. Schedule 5.22
               includes the amount of liability of Umpqua for payments more than
               thirty days past due with respect to such Welfare Benefit Plans
               as of December 31, 1999, the amount of monthly payments due and
               owing for each month that such plans are continued, and the
               amount of liability for claims if Umpqua were to terminate such
               plans and the

                                     App-28
<PAGE>   195

               costs involved in any such termination. Each Welfare Benefit Plan
               which is a group health plan (within the meaning of Section
               5000(b)(1) of the Code) complies with and has been maintained and
               operated in accordance with each of the requirements of Section
               4980B of the Code and Part 6 of Subtitle B of Title I of ERISA.
               Schedule 5.22 sets forth the individuals with rights to
               continuation coverage under Section 4980B of the Code or Part 6
               of Subtitle B of Title I of ERISA or state law, including those
               individuals within the applicable election period.

               (c) Other than as set forth in Schedule 5.22, Umpqua or any ERISA
               Affiliate has not maintained a pension benefit plan that is
               subject to title 1, subtitle B, part 3 of ERISA ("Pension Benefit
               Plan"). With respect to any such Pension Benefit Plan, the amount
               of liability for any contribution paid or owing with respect to
               such Pension Benefit Plan for the last or current plan year and
               the plan year in which the Effective Date occurs are set forth on
               Schedule 5.22. There are no other material liabilities that would
               be incurred in connection with a termination of the Plan, and the
               Plan is fully funded.

               (d) Umpqua and, to the knowledge of the executive officers and
               directors of Umpqua, all persons having fiduciary or other
               responsibilities or duties with respect to any Employee Benefit
               Plan, are, and have since inception been, in compliance in all
               material respects with, and each such Employee Benefit Plan is
               and has been operated in accordance with, its provisions and in
               compliance with the applicable laws, rules and regulations
               governing such Plan, including, without limitation, the rules and
               regulations promulgated by the Department of Labor, the Pension
               Benefit Guaranty Corporation and the Internal Revenue Service
               under ERISA or the Code. Each Pension Benefit Plan and any
               related trust agreements or annuity contracts (or any other
               funding instruments) comply currently, and have complied in the
               past, both as to form and operation, with the provisions of ERISA
               and the Code (including Section 410(b) of the Code relating to
               coverage), where required in order to be tax-qualified under
               Section 401(a) or 403(a) or other applicable provisions of the
               Code, and all other applicable laws, rules and regulations; all
               necessary governmental approvals for the Employee Benefit Plans
               have been obtained; and a favorable determination as to the
               qualification under the Code of each Pension Benefit Plan set
               forth in Schedule 5.22 and each amendment thereto has been made
               by the Internal Revenue Service. No Plan is a "multi-employer
               pension plan," as such term is defined in Section 3(37) of ERISA.
               To the best knowledge of Umpqua, all contributions or other
               amounts payable by Umpqua as of the Effective Date with respect
               to each Plan in respect of current or prior plan years have been
               paid or accrued in accordance with GAAP and Section 412 of the
               Code, and there are no pending, threatened or anticipated claims
               (other than routine claims for benefits) by, on behalf of or
               against any of the Plans or any trusts related thereto which
               would, individually or in the aggregate, have or be reasonably
               expected to have a material adverse effect on Umpqua.

               (e) Each Welfare Benefit Plan and each Pension Benefit Plan has
               been administered to date in material compliance with the
               requirements of the claims procedure of the

                                     App-29
<PAGE>   196

               Code and ERISA. All reports required by any government agency and
               disclosures to participants with respect to each Welfare Benefit
               Plan and each Pension Benefit Plan have been timely made or
               filed. Each Employee Benefit Plan has been operated since
               inception in material compliance with the governing instruments
               and applicable federal or state law. In particular, but without
               limitation, each Welfare Benefit Plan has been administered in
               material compliance with federal law, including without
               limitation the health care continuation requirements of federal
               law ("COBRA"). No Employee Benefit Plan provides benefits,
               including without limitation death or medical benefits (whether
               or not insured), with respect to current or former employees of
               Umpqua or any ERISA Affiliate beyond their retirement or other
               termination of service, other than (i) coverage mandated by
               applicable law, (ii) death benefits or retirement benefits under
               any "employee pension plan," as that term is defined in Section
               3(2) of ERISA, (iii) any deferred compensation benefits accrued
               as liabilities on the books of Umpqua or any ERISA Affiliates or
               (iv) benefits the full cost of which is borne by the current or
               former employee (or his beneficiary).

               (f) Neither Umpqua nor, to its knowledge, any plan fiduciary of
               any Welfare Benefit Plan or Pension Benefit Plan, has engaged in
               any transaction in violation of Section 406(a) or (b) of ERISA
               (for which no exemption exists under Section 408 of ERISA) or any
               "prohibited transaction" (as defined in Section 4975(c)(1) of the
               Code) for which no exemption exists under Section 4975(c)(2) or
               (d) of the Code or in any prohibited transactions under
               predecessor provisions of the Code. To the best knowledge of
               Umpqua, neither Umpqua nor any ERISA Affiliate has engaged in a
               transaction in connection with which Umpqua or any ERISA
               Affiliate could be subject to either a material civil penalty
               assessed pursuant to Section 409 or 502(i) of ERISA or a material
               tax imposed pursuant to Section 4975 or 4976 of the Code.

               (g) Umpqua has had no liability to the Pension Benefit Guaranty
               Corporation ("PBGC"). No material liability to the PBGC has been
               or will be incurred by Umpqua or other trade or business under
               "common control" with Umpqua (as determined under Section 414(c),
               (b), (m) or (o) of the Code) on account of any termination of an
               employee pension benefit plan subject to title IV of ERISA.
               Except as set forth in Schedule 5.22, since September 1, 1974, no
               filing has been made by Umpqua (or any ERISA Affiliate) with the
               PBGC (and no proceeding has been commenced by the PBGC) to
               terminate any employee pension benefit plan subject to title IV
               of ERISA maintained, or wholly or partially funded by Umpqua (or
               any ERISA Affiliate). Neither Umpqua nor any Common Control
               Entity has (i) ceased operations at a facility so as to become
               subject to the provisions of Section 4062(e) of ERISA, (ii)
               withdrawn as a substantial employer so as to become subject to
               the provisions of Section 4063 of ERISA, (iii) ceased making
               contributions on or before the Effective Date to any employee
               pension benefit plan subject to Section 4064(a) of ERISA to which
               Umpqua (or any ERISA Affiliate) made contributions during the
               five years prior to the Effective Date, or (iv) made a complete
               or partial withdrawal from a multi-employer plan (as defined in
               Section 3(37) of ERISA) so as to incur withdrawal liability as
               defined in Section 4201 of ERISA (without regard

                                     App-30
<PAGE>   197

               to subsequent reduction or waiver of such liability under Section
               4207 or 4208 or ERISA).

               (h) Complete and correct copies of the following documents have
               been furnished to VRB as Schedule 5.22:

                   (i) Each Employee Benefit Plan and any related trust
               agreements;

                   (ii) The most recent summary plan descriptions of each
               Employee Benefit Plan subject to ERISA;

                   (iii) The most recent determination letters of the Internal
               Revenue Service with respect to the qualified status of a Pension
               Benefit Plan;

                   (iv) Annual Reports (on form 5500 series) required to be
               filed with any governmental agency for the last two years;

                   (v) Financial information which identifies (x) all asserted
               or unasserted claims arising under any Employee Benefit Plan, (y)
               all claims presently outstanding against any Employee Benefit
               Plan, and (z) a description of any future compliance action
               required with respect to any Employee Benefit Plan under ERISA,
               or federal or state law.

                   (vi) Any actuarial reports and PBGC Forms 1 for the last 2
               years.

               (i) Each Welfare Benefit Plan and each Pension Benefit Plan is
               legally valid and binding and in full force and effect and there
               are no defaults thereunder.

        5.23.  Employment Disputes. There is no labor strike, dispute, slowdown
               or stoppage pending or, to the best knowledge of Umpqua,
               threatened against Umpqua, and Umpqua does not have any knowledge
               of any attempt to organize any employees of Umpqua or Surviving
               Bank into a collective bargaining unit. Consummation of the Plans
               of Merger will not (either alone or in combination with any other
               act or event) result in any payment of severance pay or any other
               payment becoming due from Umpqua to any of its employees except
               as set forth in Schedule 5.23. Umpqua is not a party to any
               agreement involving payments to any person or entity based upon
               the profits, revenues or other financial performance of Umpqua
               except as set forth on Schedule 5.23.

        5.24.  Reserve for Loan Losses. Umpqua's reserve for loan losses, as
               established from time to time, is adequate as determined by the
               standards applied to Umpqua and Surviving Bank by the applicable
               bank regulatory agencies and pursuant to generally accepted
               accounting principles. Since March 31, 2000, Umpqua has not and
               prior to the Effective Date shall not, reverse any provision
               taken for loan losses.


                                     App-31
<PAGE>   198

        5.25.  Repurchase Agreement. Umpqua has valid and perfected first
               position security interests in all government securities subject
               to repurchase agreements and the market value of the collateral
               securing each such repurchase agreement equals or exceeds the
               amount of the debt secured by such collateral under such
               agreement.

        5.26.  Shareholder List. The list of shareholders of Umpqua dated June
               30, 2000, provided to VRB, is a true, correct and complete list
               of the names, addresses and holdings of all record holders of
               Umpqua Common Stock as of that date. Based upon the information
               made available to Umpqua and on filings with the SEC pursuant to
               Section 13(d) and 16(a) of the Exchange Act, Umpqua shall notify
               VRB of any change in such stock ownership of over one percent
               (1%) through the Effective Date.

        5.27.  Proxy Statement. The registration statement to be filed by Umpqua
               with the Oregon Director and the Proxy Statement to be used by
               Umpqua to solicit proxies from the holders of Umpqua Common Stock
               for the meeting of shareholders held to consider and vote upon
               this Agreement and the Holding Company Plan of Merger, and the
               transactions contemplated thereby (in its definitive form the
               "Proxy Statement"), will fairly describe the transaction and
               Umpqua, and will contain no untrue statement of any material fact
               and will not omit to state any material fact required to be
               stated therein or necessary to make the statements therein not
               misleading, except those statements in or omission from the Proxy
               Statement which may be made with respect to VRB. Umpqua will
               promptly advise VRB in writing if at any time prior to the
               Effective Date Umpqua shall obtain knowledge of any facts that
               might make it necessary or appropriate to amend or supplement the
               Proxy Statement in order to make the statements therein not
               misleading or to comply with applicable law.

        5.28.  Interests of Directors and Others. Except as disclosed in any
               Umpqua Public Reports, no officer or director of Umpqua or
               Surviving Bank has any material interest in any assets or
               property (whether real or personal, tangible or intangible), of
               or used in the business of Umpqua or Surviving Bank other than as
               an owner of outstanding securities or deposit accounts of Umpqua
               or Surviving Bank, or as borrowers under loans fully performing
               in accordance with their terms, which terms are no more favorable
               than those available to unaffiliated parties made at or about the
               same time.

        5.29.  Schedules to this Agreement. The information contained in each
               schedule to this Agreement prepared by or on behalf of Umpqua
               constitutes additional representations and warranties made by
               Umpqua hereunder and is incorporated herein by reference. The
               copies of documents furnished as part of these schedules are
               true, correct and complete copies and include all amendments,
               supplements, and modifications thereto and all express waivers
               applicable thereunder.

        5.30.  No Misstatements or Omissions. No representation or warranty of
               Umpqua or Surviving Bank in this Agreement or in any statement,
               certificate or schedule

                                     App-32

               furnished or to be furnished by Umpqua pursuant to this Agreement
               or in connection with the transaction contemplated by this
               Agreement, contains or will contain any untrue statements of a
               material fact or omits or will omit to state any material fact.

6.      COVENANTS OF VRB

        6.1.   Certain Actions. During the period between the date hereof and
               the earlier of the Effective Date or the termination of this
               Agreement, VRB covenants to Umpqua for itself and on behalf of
               Valley, that, without first obtaining the written approval of
               Umpqua:

               (a) It shall not amend its Articles of Incorporation or Bylaws;

               (b) It shall not declare or pay any dividend (except VRB's
               regular $0.12 per share semi-annual dividend with a record date
               in October 2000), redeem, repurchase or otherwise acquire or
               agree to acquire any of VRB's Stock; or make or commit to make
               any other distribution to VRB's stockholders;

               same in good faith and, if appropriate, has established
               reasonable reserves therefore, VRB will promptly pay all taxes
               and assessments indicated by tax returns as due or otherwise
               lawfully levied or assessed upon it or any of its properties and

               orders, including but not limited to approval of the FDIC, FRB
               and the Oregon Director, to the transactions contemplated by this
               Agreement and the Plans of Merger, and to obtain the approval of
               the shareholders of VRB to the Agreement and to the Plans of
               Merger. Further, VRB will use its reasonable best efforts to

               Date or the termination of this Agreement, VRB will not take any
               action which would cause or constitute a breach of any of the
               representations or warranties of VRB contained in this Agreement
               or which would cause any such representations or warranties, if
               made on and as the date of such event or the Effective Date, to
               be untrue or inaccurate in any material respect (other than an
               event so affecting a representation or warranty which is
               permitted hereby or is expressly limited to a state of facts
               existing at a time prior to the occurrence of such event).
               Promptly upon becoming aware of the occurrence of or the pending
               or threatened occurrence of any event which would cause or
               constitute such a breach or inaccuracy, VRB will give detailed
               written notice thereof to Umpqua and will use its best efforts to

               and the Chief Financial Officer of VRB, dated as of the Effective
               Date, certifying to the best of their knowledge the fulfillment

               the Plans of Merger will be a reorganization within the meaning
               of Section 368 of the Code; that the parties to the Agreement and
               to the Plans of Merger will each be "a party to a reorganization"
               within the meaning of Section 368(b) of the Code; and no taxable
               gain or loss will be recognized by the shareholders of VRB who
               will receive solely Umpqua Common Stock (except for cash, if any,
               received in lieu of fractional shares); that the basis in the
               Umpqua Common Stock to be received by the recipients will be the
               same as the basis in their VRB Common Stock exchanged (except for
               cash to be received for any fractional share interests); and
               that, provided the stock exchanged was held as a capital asset on
               the Effective Date, the holding period of the Umpqua Common Stock
               to be received will include the holding period of the VRB Common
               Stock previously held, prior to the Effective Date.

               effect that the financial terms of the transactions contemplated
               by this Agreement are financially fair to Umpqua's shareholders.
               VRB will provide Umpqua's investment advisor such information as
               it may reasonably request in order to render its opinion.

        8.15.  Accounting Treatment. It will have been determined to the
               satisfaction of Umpqua that the Holding Company Merger will be
               treated for accounting purposes as a

                                     App-46
<PAGE>   213

               "pooling of interests" in accordance with APB Opinion No. 16, and
               the related interpretations of the AICPA consensuses of the
               FASB's Emerging Issue Task Force, and the rules and regulations

               VRB and its counsel to the effect that:

               (a) Umpqua is a corporation, duly organized and validly existing
               under the laws of the State of Oregon, and has all requisite
               corporate power and authority to own,

               power and authority to execute, deliver and perform its
               obligations under the Agreement and the Plans of Merger; the
               execution, delivery and performance of the Agreement and the
               Plans of Merger and the consummation of the transactions
               contemplated thereby, have been duly authorized by all requisite
               corporate action on the part of each; and the Agreement and the
               Plans of Merger have been duly executed and delivered by them and
               constitute the legal, valid and binding obligation of each,
               enforceable in accordance with its terms, except as the same may
               be limited by bankruptcy, insolvency, reorganization, moratorium
               or similar laws or by equitable principles;

               (d) The authorized capital stock of Umpqua consists of 2,000,000
               shares of preferred stock, no par value per share, none of which

               no par value per share, of which [COMPLETE AS OF THE EFFECTIVE
               DATE] shares are outstanding and are validly issued, fully paid
               and nonassessable. Such shares are the only shares of capital
               stock of Umpqua authorized, issued or outstanding; and to the
               best of knowledge of Foster Pepper & Shefelman LLP, Umpqua is not

               Umpqua Public Reports.

the shares of VRB Common Stock, will be authorized, validly issued, fully paid
and nonassessable; and

               (g) The Umpqua Common Stock to be issued to the VRB shareholders
               has been registered under Oregon securities laws, and is exempt
               from registration under the Securities Act and to the best of
               Foster Pepper & Shefelman LLP's knowledge, no stop order

               proceeding for that purpose has been initiated or pending or are
               contemplated under the Act or any other securities laws. The
               issuance of Umpqua Common Stock has been registered or qualified
               or is exempt from registration or qualification except when such
               failure would not (i) be material to Umpqua, or (ii) pose a
               material risk of material liability

               under the Act (other than that Umpqua Common Stock issued to
               persons to whom Rule 145 applies).

        9.7.   Corporate Documents. Receipt by VRB of:

               (a) Current certificate of existence and good standing
               certificate for Umpqua and Surviving Bank, respectively, issued

               discovery of a claim against Umpqua or any other obligation or
               liability of Umpqua, not previously known, of less than $250,000
               individually or $500,000 in the aggregate shall not be deemed a

        9.9.   Compliance with Covenants and Conditions. Umpqua having complied
               with all agreements, covenants and conditions on their part

               effect that the transaction contemplated by the Agreement and the
               Plans of Merger will be a reorganization within the meaning of
               Section 368 of the Code; that the parties to the Agreement and to
               the Plans of Merger will each be "a party to a reorganization"
               within the meaning of Section 368(b) of the Code; and no taxable
               gain or loss will be recognized by the shareholders of VRB who
               will receive solely Umpqua Common Stock (except for cash, if any,
               in lieu of fractional shares); that the basis in the Umpqua
               Common Stock to be received by the recipients will be the same as
               the basis in their VRB Common Stock (except for cash to be
               received for any fractional share interests); and that, provided
               the stock

                                     App-49
<PAGE>   216

               exchanged was held as a capital asset on the Effective Date, the
               holding period of the Umpqua Common Stock to be received will
               include the holding period of the VRB Common Stock previously
               held, prior to the Effective Date.

               fulfillment by Umpqua of any of the conditions of this Agreement
               as VRB may reasonably request.

        9.13.  Fairness Opinion. VRB will have received from D.A. Davidson & Co.
               an opinion, dated as of the date the Board of Directors of VRB
               shall have approved this Agreement and updated immediately before
               VRB mails the Proxy Statement to its shareholders, to the effect
               that the financial terms of the Merger are financially fair to
               VRB's shareholders. Umpqua will provide VRB's investment advisor

               its opinion.

        9.14.  Accounting Treatment. It will have been determined to the
               satisfaction of VRB that the Holding Company Merger will be
               treated for accounting purposes as a "pooling of interests" in

               interpretations of the AICPA consensuses of the FASB's Emerging
               Issue Task Force, and the rules and regulations of the SEC, and
               VRB will have received a letter to such effect from Deloitte &
               Touche LLP, certified public accountants.

               (b) By Umpqua or VRB acting through their Boards of Directors
               upon written notice to the other parties, if (i) at the time of
               such notice the Mergers shall not

               have become effective by March 31, 2001 (or such later date as
               shall have been agreed to in writing by Umpqua and VRB acting
               through their respective Boards of Directors), (ii) shareholders
               of VRB shall not have approved the Agreement, the Plans of Merger
               and the transactions contemplated thereby prior to March 31,
               2001, (iii) shareholders of Umpqua shall not have approved the
               Agreement, the Plans of Merger and the transactions contemplated
               thereby and the issuance of the Umpqua Common Stock prior to
               March 31, 2001, or (iv) Deloitte & Touche LLP, Umpqua's auditors,
               advise that the transaction proposed by the Agreement and the
               Plans of Merger would not be accounted for as a
               pooling-of-interests;

               (c) By Umpqua, acting through its Board of Directors upon written
               notice to VRB, if there has been a material misrepresentation or
               material breach on the part of VRB in its representations,
               warranties and covenants set forth herein or if there has been
               any material failure on the part of VRB to comply with its
               obligations hereunder which misrepresentation, breach or failure
               is not cured within thirty (30) days notice to VRB of such
               misrepresentation, breach or failure; or by VRB, acting through
               its Board of Directors upon written notice to Umpqua, if there
               has been a material misrepresentation or material breach by
               Umpqua in its representations, warranties and covenants set forth
               herein or if there has been a material failure on the part of
               Umpqua to comply with its obligations hereunder which
               misrepresentation, breach or failure is not cured within thirty
               (30) days notice to Umpqua of such misrepresentation, breach or
               failure;

               (d) By Umpqua upon advice of Foster Pepper & Shefelman LLP that
               the fiduciary duties of the Directors so require; and

               (e) By VRB upon advice of Davis Wright Tremaine LLP that the
               fiduciary duties of the Directors so require.

               (f) By VRB, in accordance with the following provisions:

                   (i) At any time during the five-business-day period
               commencing on the tenth calendar day preceding the Effective
               Date, if both of the following conditions are satisfied:

                      (A) The Average Closing Price is less than $6.75; and

                      (B) The number, expressed as a percentage, obtained by
                      dividing the Average Closing Price by $8.15 is more than
                      ten percentage points less than the Index Differential.

               Provided however, if the Average Closing Price is $6.10 or higher
               and Umpqua notifies VRB at least two days (2) prior to the
               Effective Date of its election to increase the exchange ratio in
               accordance with the following formula, any notice given by VRB
               under this Section 11 (f) shall be deemed withdrawn and the
               Exchange Ratio shall be the number (carried out to four
               significant digits)

                                     App-51
<PAGE>   218

               calculated by multiplying 0.8135 times $6.75 and dividing that
               product by the Average Closing Price, but in no event will the
               Exchange Ratio calculated by this formula be greater than 0.8500.

                   (ii) Definitions. For the purposes of this Section 11.1(f) of
               this Agreement, the following terms shall have the meanings set
               forth in this Subparagraph (ii). Additional terms may be defined
               elsewhere herein.

                             (A) "Average Closing Price." The average (rounded
               to the nearest penny) of each Daily Sales Price of Umpqua Common
               Stock for the twenty consecutive trading days ending on and
               including the tenth calendar day preceding the projected
               Effective Date (or, if that calendar day is not a trading day,
               the most closely preceding day that is a trading day).

                             (B) "Average Bank Index." The average of the
               closing Nasdaq Bank Index (Bloomberg-CBNK) for the twenty
               consecutive trading days ending on and including the tenth
               calendar day preceding the projected Effective Date (or, if that
               calendar day is not a trading day, the most closely preceding day
               that is a trading day).

                             (C) "Daily Sales Price." For any trading day,
               subject to the following sentence, the last reported trade price
               as such prices are reported by the automated quotation system of
               the National Association of Securities Dealers, Inc., or in the
               absence thereof by such other source upon which Umpqua and VRB
               shall mutually agree. If there are no reported trades on any
               trading day, such day shall be deemed to be a non-trading day.

                             (D) "Index Differential." The number, expressed as
               a percentage, obtained by dividing the Average Bank Index by
               1,588.3.

        11.2.  Effect of Termination.

              11.2.1. In the event this Agreement is terminated pursuant to
                      Section 11.1(a), 11.1(b)(i), or 11.1(b)(iv), it shall
                      become wholly void and of no further force and effect and
                      there shall be no liability on the part of any party or
                      their respective Boards of Directors as a result of such
                      termination or abandonment.

              11.2.2. If the Agreement is terminated by VRB or Umpqua pursuant
                      to Section 11.1(b)(ii), by Umpqua pursuant to Section
                      11.1(c) or by VRB pursuant to Section 11.1(e) or (f), then
                      VRB agrees to pay to Umpqua its reasonable expenses
                      incurred in entering into and attempting to consummate the
                      transaction. In addition to the foregoing, if, prior to
                      December 31, 2001, VRB enters into an Alternative
                      Acquisition Transaction and (a) an Alternative Acquisition
                      Transaction had been proposed prior to the date of the VRB
                      shareholder meeting or (b) at the

                                     App-52
<PAGE>   219

                      time of such shareholder meeting VRB or its Directors fail
                      to materially comply with the covenants set forth in
                      Section 6, and in either event if at the time of VRB's
                      shareholder meeting there was no material failure by
                      Umpqua to meet the conditions set forth in Section 9, then
                      VRB will, within thirty (30) days after Umpqua's request,
                      pay Umpqua an additional $3,000,000. This Section 11.2.2
                      shall be the sole remedy in favor of Umpqua for
                      termination of this Agreement pursuant to the sections
                      named in the preceding sentence, and Umpqua specifically
                      waives the protections of any equitable remedies that
                      otherwise might be available to Umpqua.

              11.2.3. If the Agreement is terminated by Umpqua or VRB pursuant
                      to Section 11.1(b)(iii), by VRB pursuant to Section
                      11.1(c) or by Umpqua pursuant to Section 11.1(d), then
                      Umpqua agrees to pay to VRB its reasonable expenses
                      incurred in entering into and attempting to consummate the
                      transaction. In addition to the foregoing, if, prior to
                      December 31, 2001, Umpqua enters into an Alternative
                      Acquisition Transaction and (a) an Alternative Acquisition
                      Transaction had been proposed at the time of the Umpqua
                      shareholder meeting or (b) at the time of such
                      shareholders meeting Umpqua or its Directors fail to
                      materially comply with the covenants set forth in Section
                      7, and in either event if at the time of Umpqua's
                      shareholders meeting there was no material failure by VRB
                      to meet the conditions set forth in Section 8, then Umpqua
                      will, within thirty (30) days after VRB's request, pay VRB
                      an additional $3,000,000. This Section 11.2.2 shall be the
                      sole remedy in favor of VRB for termination of this
                      Agreement pursuant to the sections named in the preceding
                      sentence, and VRB specifically waives the protections of
                      any equitable remedies that otherwise might be available
                      to VRB.

        11.3.  Documents from VRB. In the event of termination of this
               Agreement, Umpqua will promptly deliver to VRB all originals and
               copies of documents and work papers obtained by Umpqua from VRB,
               whether so obtained before or after the execution hereof, and
               will not use any information so obtained, and will not disclose
               or divulge such information so obtained; provided, however, that
               any disclosure of such information may be made to the extent
               required by applicable law or regulation or judicial or
               regulatory process; and provided further that Umpqua shall not be
               obligated to treat as confidential any such information which is
               publicly available or readily ascertainable from public sources,
               or which was known to Umpqua at the time that such information
               was disclosed to it by VRB or which is rightfully received by
               Umpqua from a third party. The obligations arising under this
               Section 11.3 shall survive any termination or abandonment of this
               Agreement.

        11.4.  Documents from Umpqua. In the event of termination of this
               Agreement, VRB will promptly deliver to Umpqua all originals and
               copies of documents and work papers obtained by VRB from Umpqua,
               whether so obtained before or after the execution hereof, and
               will not use, disclose or divulge any information so obtained;
               provided,

                                     App-53
<PAGE>   220

               however, that any disclosure of such information may be made to
               the extent required by applicable law, regulation or judicial or
               regulatory process; and provided further, VRB shall not be
               obligated to treat as confidential any information which is
               publicly available or readily ascertainable from public sources,
               or which was known to VRB at the time that such information was
               disclosed to it by Umpqua or which is rightfully received by VRB
               from a third party. The obligations arising under this Section
               11.4 shall survive any termination or abandonment of this
               Agreement.

12.     MISCELLANEOUS PROVISIONS

        12.1.  Amendment or Modification. Prior to the Effective Date, this
               Agreement and the Plans of Merger may be amended or modified,
               either before or after approval by the shareholders of VRB and
               Umpqua, only by an agreement in writing executed by the parties
               hereto upon approval of their respective boards of directors;
               provided, however, that no such amendment or modification shall
               increase the amount or modify the form of consideration to be
               received by the VRB shareholders pursuant to the Holding Company
               Plan of Merger without the approval of the Umpqua shareholders,
               or decrease the amount or modify the form of consideration to be
               received by the VRB shareholders pursuant to the Holding Company
               Plan of Merger without the approval of the VRB shareholders.

        12.2.  Public Statements. No party to this Agreement shall issue any
               press release or other public statement concerning the
               transactions contemplated by this Agreement without first
               providing the other parties hereto with a written copy of the
               text of such release or statement and obtaining the consent of
               the other parties to such release or statement, which consent
               will not be unreasonably withheld. The consent provided for in
               this section shall not be required if the delay would preclude
               the timely issuance of a press release or public statement
               required by law or any applicable regulations. The provisions of
               this section shall not be construed as limiting the parties from
               communications consistent with the purposes of this Agreement,
               including but not limited to seeking regulatory and shareholder
               approvals necessary to complete the transactions contemplated by
               this Agreement and the Plans of Merger.

        12.3.  Confidentiality. Each party shall use the non-public information
               that it obtains from the other parties to this Agreement solely
               for the effectuation of the transactions contemplated by this
               Agreement and the Plans of Merger or for other purposes
               consistent with the intent of this Agreement and shall not use
               any such information for other purposes, including but not
               limited to the competitive detriment of the other parties. Each
               party shall maintain strictly confidential all non-public
               information it receives from the other parties and shall, upon
               termination of this Agreement prior to the Effective Date, return
               such information in accordance with Sections 11.3 and 11.4
               hereof. The provisions of this section shall not prohibit the use
               of information consistent with the provisions of those sections
               or to prohibit disclosure of information to the parties
               respective counsel, accountants, tax

               advisors, and consultants, provided that those parties also agree
               to maintain such information confidential in accordance with this
               section and Sections 11.3 and 11.4 hereof.

        12.4.  Waivers and Extensions. Each of the parties hereto may, by an
               instrument in writing, extend the time for or waive the
               performance of any of the obligations of the other parties hereto
               or waive compliance by the other parties hereto of any of the
               covenants or conditions contained herein or in the Plans of
               Merger, other than those required by law. No such waiver or
               extension of time shall constitute a waiver of any subsequent or
               other performance or compliance. No such waiver shall require the
               approval of the shareholders of any party.

        12.5.  Expenses. Each of the parties hereto shall pay their respective
               expenses in connection with this Agreement and the Plans of
               Merger and the transactions contemplated thereby, except as
               otherwise may be specifically provided.

        12.6.  Financial Advisors. Each party is solely responsible for the
               payment of their own financial advisor fees.

        12.7.  Binding Effect, No Assignment. This Agreement and all the
               provisions hereof shall be binding upon and inure to the benefit
               of the parties hereto and their respective successors and
               permitted assigns, but neither this Agreement nor any of the
               rights, interests or obligations hereunder, shall be assigned by
               any of the parties hereto without the prior written consent of
               the other parties.

        12.8.  Representations and Warranties. The respective representations
               and warranties of each party hereto contained herein shall not be
               deemed to be waived or otherwise affected by any investigation
               made by the other parties, and except for claims based upon fraud
               of the parties or their representatives, shall not survive the
               closing hereof.

        12.9.  Remedies. Except for claims based upon fraud of the parties or
               their representatives, the only remedy available to any party
               hereunder is for amounts payable pursuant to Section 11.2.

        12.10. No Benefit to Third Parties. Nothing herein expressed or implied
               is intended or shall be construed to confer upon or give any
               person or entity, other than the parties hereto, any right or
               remedy under or by reason hereof.

        12.11. Notices. Any notice, demand or other communication permitted or
               desired to be given hereunder shall be in writing and shall be
               deemed to have been sufficiently given or served for all purposes
               if personally delivered or mailed by registered or certified
               mail, return receipt requested, or sent via confirmed facsimile

        12.14. Headings. The article and section headings in this Agreement are
               for the convenience of the parties and shall not affect the
               interpretation of this Agreement.

        12.15. Counterparts. At the convenience of the parties, this Agreement
               may be executed in counterparts, and each such executed
               counterpart shall be deemed to be an original instrument, but all
               such executed counterparts together shall constitute but one
               Agreement.

        12.16. Non-Competition Agreement. Except as may be consented to in
               writing by Umpqua, each non-employee member of the Board of
               Directors of VRB and Umpqua signing at the end of this Agreement
               agrees that he/she will not, for a period of two years following
               his/her service on the Board of Directors of Umpqua, or Surviving
               Bank, VRB or Valley, as the case may be, be associated in any way
               with any financial institution other than Umpqua (or any of its
               affiliates) with branches in Jackson, Josephine, Lane, Marion,
               Multnomah or Douglas Counties, Oregon, whether directly or
               indirectly, alone or as a member of a partnership, or as an
               officer, director, stockholder or employee; provided, however,
               for any Director not serving in such position following the
               Effective Date, the limitation shall be restricted to Jackson and
               Josephine Counties for any VRB Director or Lane, Marion,
               Multnomah and Douglas Counties, for any Umpqua Director.
               Ownership of less than one percent of the stock of a publicly
               held corporation shall not be deemed to be prohibited by this
               provision.

        12.17. Restrictions On Transfer. Umpqua will not deliver any Umpqua
               Common Stock into which the outstanding shares of VRB are to be
               converted pursuant to the provisions of the Holding Company Plan
               of Merger to any shareholder who, in the opinion of counsel for
               Umpqua, is or may be an "affiliate" (as defined in Rule 144
               promulgated by the SEC pursuant to the Securities Act) of VRB,
               except upon receipt by Umpqua of a letter or other written
               commitment from that shareholder to comply with Rule 145 as
               promulgated by the SEC, in a form reasonably acceptable to its
               counsel.

               The certificates representing shares to be issued to "affiliates"
               of VRB will bear the following legend until such time as Umpqua
               shall have received an opinion of counsel satisfactory to Umpqua
               to the effect that the shares may be transferred without
               restriction and that the legend is no longer needed:

                      "The shares represented by this certificate (i) were
                      issued pursuant to a business combination and (ii) may be
                      sold only in accordance with the provisions of Rule 145
                      under the Securities Act of 1933, as amended (the "Act"),
                      or pursuant to an effective registration statement under
                      the Act or an exemption therefrom."

        12.18. Pooling Accounting.


                                     App-57
<PAGE>   224

               (a) The parties hereto intend for the Holding Company Merger to
               be treated as a pooling of interests for accounting purposes.
               From and after the date of this Agreement and until the Effective
               Date, neither Umpqua nor VRB nor any of their affiliates (i)
               shall knowingly take any action, or shall knowingly fail to take
               any action, that would jeopardize the treatment of the Holding
               Company Merger as a "pooling of interests" for accounting
               purposes; or (ii) shall enter into any contract, agreement,
               commitment or arrangement with respect to the foregoing;
               provided, however, that no action or omission by any party shall
               constitute a breach of this sentence if such action or omission
               is specifically permitted by the terms of this Agreement or is
               made with the written consent of the other parties hereto. The
               members of the Board of Directors of VRB and Valley may be deemed
               to be "affiliates" of VRB ("VRB Affiliates") for purposes of the
               SEC's Codification of Financial Reporting Policies Section 201.01
               and the SEC's Staff Accounting Bulletin No. 65 (collectively "SAB
               65"). Umpqua will receive from each person so identified a
               written agreement in the form of Schedule 12.18. Prior to the
               Effective Date, VRB agrees to use all reasonable efforts to cause
               any additional person who becomes or is identified as a "VRB
               Affiliate" to execute such a letter agreement.

        (b) Umpqua shall have the right to place a restrictive legend on all
shares of Umpqua Common Stock to be received by a VRB Affiliate so as to
preclude their transfer or disposition in violation of such letter agreement, to
instruct its transfer agent not to permit the transfer of any such shares and/or
to take any other steps reasonably necessary to ensure compliance with SAB 65.
Prior to 30 days before the Effective Date, stock certificates evidencing
ownership of all VRB Common Stock by VRB Affiliates shall be delivered to VRB
and VRB (prior to the Effective Date) and Umpqua (after the Effective Time)
shall retain such certificates or the certificates of Umpqua Common Stock into
which they are exchanged until such time as financial results covering at least
30 days of combined operations of Umpqua and VRB shall have been published, at
which time such certificates shall be released. Umpqua covenants and agrees to
promptly return such certificates to the VRB Affiliates with such restrictive
legends removed after the publication of such combined results.

                EXHIBIT A TO AGREEMENT AND PLAN OF REORGANIZATION

                                 PLAN OF MERGER

        This Plan of Merger (the "Plan of Merger") is dated __________, 2000,
and is by and between Umpqua Holdings Corporation ("Umpqua"), an Oregon
corporation, and VRB Bancorp ("VRB"), an Oregon corporation.

                                    RECITALS

        A. The Board of Directors of each of Umpqua and VRB has approved this
Plan of Merger and authorized its execution and the performance of all of its
obligations hereunder.

        B. This Plan of Merger is part of an Agreement and Plan of
Reorganization, dated as of August 14, 2000, by and among Umpqua, VRB, South
Umpqua Bank (Umpqua's wholly owned subsidiary bank) and Valley of the Rogue Bank
(VRB's wholly owned subsidiary bank), which agreement sets forth certain
conditions precedent to the effectiveness of this Plan of Merger and other
matters relative to the merger contemplated by this Plan of Merger (the
"Merger"), including certain defined terms.

        C. At or prior to the date the Merger becomes effective, the parties
shall have taken all such actions as may be necessary or appropriate in order to
effectuate the Merger.

                                    AGREEMENT

        In consideration of the mutual covenants herein contained, the parties
hereby adopt this Plan of Merger:

        1. EFFECTIVE DATE AND TIME. This Plan of Merger shall be effective at
the time (the "Effective Time") of filing of Articles of Merger with the Oregon
Secretary of State. The date on which the Articles of Merger are filed is
referred to herein as the "Effective Date".

        2. MERGER. At the Effective Time, VRB shall merge with and into Umpqua,
which will be the surviving corporation (the "Merger"). The name of the
surviving corporation shall be "Umpqua Holdings Corporation".

        3. ARTICLES OF INCORPORATION, BYLAWS, DIRECTORS, OFFICERS. Until
altered, amended or repealed, the Articles of Incorporation and Bylaws of Umpqua
on the Effective Date shall be the Articles of Incorporation and Bylaws of the
surviving corporation. Until their successors are elected or appointed and
qualified, and subject to prior death, resignation or removal, the officers and
directors of Umpqua shall be, as of the Effective Date, the individuals
identified in Appendix A hereto serving the terms designated.

        4. EFFECTIVE OF MERGER. Until changed by the Board of Directors of
Umpqua, all corporate acts, plans, policies, contracts, approvals and
authorizations of Umpqua and VRB, and their shareholders, officers, agents,
Boards of Directors, and committees elected or


                                     App-61
<PAGE>   228

appointed thereby, which were valid and effective immediately prior to the
Effective Date shall be taken for all purposes as the acts, plans, policies,
contracts, approvals and authorizations of Umpqua and shall be as effective and
binding thereon as the same were with respect to Umpqua and VRB prior to the
Effective Date.

                4.1 At the Effective Date, the corporate existence of Umpqua and
VRB shall, as provided by Oregon law, be merged into and continued in Umpqua,
and the separate existence of Umpqua and VRB shall terminate. All rights,
franchises and interests of Umpqua and VRB, respectively, in and to every type
of property (whether real, personal, tangible or intangible) and chooses in
action shall be transferred to and vested in Umpqua by virtue of the Merger
without any deed or other transfer, and Umpqua, without any order or action on
the part of any court or otherwise, shall hold and enjoy all such rights and
property, franchises, and interests, including appointments, designations and
nominations, and in every other fiduciary capacity, in the same manner and to
the same extent as such rights, franchises, and interests were held or enjoyed
by Umpqua and VRB, respectively, on the Effective Date.

                4.2 On the Effective Date, the liabilities of Umpqua and VRB
shall become the liabilities of Umpqua, and all debts, liabilities, and
contracts of Umpqua and VRB, respectively, matured or unmatured, whether
accrued, absolute, contingent or otherwise, and whether or not reflected or
reserved against on balance sheets, books of accounts, or records of Umpqua and
VRB, shall be those of Umpqua and shall not be released or impaired by the
Merger; and all rights of creditors and other obligees and all liens on property
shall be preserved unimpaired.

        5. CAPITALIZATION OF UMPQUA. The present authorized capital of Umpqua
consists of 2,000,000 shares of undesignated preferred stock with no par value
of which no shares are issued or outstanding and 20,000,000 shares of common
stock without par value of which [INSERT LAST NUMBER AT TIME OF FILING] shares
are, issued outstanding and fully paid ("Umpqua Common Stock"). Except as set
forth in the Reorganization Agreement or the schedules thereto, there are no
outstanding options, warrants or other rights to purchase or receive Umpqua
securities.

        6. CAPITALIZATION OF VRB. The present authorized capital of VRB consists
of 10,000,000 shares of undesignated preferred stock, with $5.00 par value per
share, of which no shares are issued or outstanding and 30,000,000 shares of
common stock without par value, of which [INSERT LAST NUMBER AT TIME OF FILING]
shares are issued outstanding and fully paid ("VRB Common Stock"). Except as set
forth in the Reorganization Agreement or the schedules thereto, there are no
outstanding options, warrants or other rights to purchase or receive VRB
securities.

        7. EXCHANGE OF SHARES. At the Effective Time, by virtue of the Merger
and without any action on the part of any party or any shareholder, the
following shall occur:

                7.1 Each share of Umpqua Common Stock outstanding immediately
prior to the Merger shall remain outstanding.

                7.2 Each outstanding share of VRB Common Stock shall be
converted into the right to receive [INSERT EXCHANGE RATIO AS DETERMINED FROM
THE AGREEMENT AND PLAN OF


                                     App-62
<PAGE>   229

REORGANIZATION] shares of Umpqua Common Stock, except that cash shall be paid in
lieu of any resulting fractional shares as set forth below in Section 8.

                7.3 All of the shares of VRB Common Stock, whether issued or
unissued, will be canceled and the holders of certificates for shares thereof
shall cease to have any rights as shareholders of VRB, other than the right to
receive any dividend or other distribution with respect to such VRB Common Stock
with a record date occurring prior to the Effective Time and the right to
receive Umpqua Common Stock as provided above. After the Effective Time, the
stock transfer register of VRB shall be closed, and there shall be no transfers
of shares of VRB Common Stock recorded on the stock transfer books of VRB.

                7.4 All existing stock option plans of VRB shall terminate, no
options thereunder shall be granted, and each outstanding option to acquire VRB
Common Stock (each a "VRB Option") shall automatically be converted and
exchanged into an Umpqua stock option (a "Converted Option") to purchase shares
of Umpqua Common Stock, and each shall continue on the same terms upon which
granted; provided that (i) the number of shares of Umpqua Common Stock issuable
upon exercise of the Converted Option shall be equal to the product of (a) the
number of shares of VRB Common Stock issuable upon exercise of the VRB Option,
and (b) [INSERT EXCHANGE RATIO AS DETERMINED FROM THE AGREEMENT AND PLAN OF
REORGANIZATION]; and (ii) the exercise price of such Converted Option shall be
equal to the result of (a) the exercise price of the VRB Option, divided by (b)
[INSERT EXCHANGE RATIO AS DETERMINED FROM THE AGREEMENT AND PLAN OF
REORGANIZATION]; provided, however, that all other terms and conditions of such
outstanding options, including vesting schedules, if any, and aggregate exercise
price, shall not be affected by the Merger except as may be set forth in such
option agreements. With respect to any VRB Option that is an incentive stock
option within the meaning of Section 422 of the Code, the foregoing adjustments
shall be effected in a manner consistent with Section 424(a) of the Code.

        8. NO FRACTIONAL SHARES. Notwithstanding any other provision hereof, no
fractional shares of Umpqua Common Stock and no certificates or scrip therefor,
or other evidence of ownership thereof, will be issued. Instead, Umpqua will pay
to each holder of VRB Common Stock who would otherwise be entitled to a
fractional share of Umpqua Common Stock an amount in cash (without interest)
determined by multiplying such fraction by the closing price for Umpqua Common
Stock on the Effective Date as reported by the Nasdaq National Market.

        9. EXCHANGE PROCEDURES.

                9.1 At or promptly after the Effective Time, Umpqua shall
deposit or cause to be deposited with Chase Mellon Shareholder Services, (the
"Exchange Agent") for the benefit of the holders of certificates for VRB Common
Stock, for exchange in accordance with this Plan of Merger, certificates
representing the shares of Umpqua Common Stock ("New Certificates") for which
outstanding shares of VRB Common Stock are to be exchanged in connection with
the Merger and cash sufficient to make payment in lieu of fractional shares in
accordance with Section 8 hereof.

                9.2 As promptly as practicable after the Effective Time, the
Exchange Agent shall send or cause to be sent to each holder of record of VRB
Common Stock transmittal materials for use in exchanging such shareholders' VRB
Common Stock certificates for the consideration set


                                     App-63
<PAGE>   230

forth in this Plan of Merger. Umpqua shall cause the New Certificates into which
a shareholder's VRB Common Stock is converted at the Effective Time, and checks
for fractional share interests or dividends or distributions such person shall
be entitled to receive, to be delivered to such shareholder upon delivery to the
Exchange Agent of certificates representing such VRB Common Stock (or indemnity
reasonably satisfactory to Umpqua and the Exchange Agent, if any of such
certificates are lost, stolen or destroyed) owned by such holder. No interest
will be paid on any such cash to be paid pursuant to this Plan of Merger upon
such delivery. The transmittal materials will specify that delivery of
certificates theretofore representing VRB Common Stock shall be effected, and
risk of loss and title to the VRB Common Stock certificates will pass, if and
only if proper delivery of such certificates is made to the Exchange Agent.

        9.3 Notwithstanding the foregoing, neither the Exchange Agent nor any
party hereto shall be liable to any former holder of VRB Common Stock for any
amount properly delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.

        9.4 No dividends or other distributions with respect to Umpqua Common
Stock with a record date occurring after the Effective Time shall be paid to the
holder of any unsurrendered certificates representing shares of VRB Common Stock
converted in the Merger into shares of Umpqua Common Stock until the holder
thereof shall surrender such certificates in accordance with this Plan of
Merger. After the surrender in accordance with this Plan of Merger, the record
holder thereof will be entitled to receive any such dividends or other
distributions, without any interest thereon, which theretofore had become
payable with respect to shares of Umpqua Common Stock represented by such
certificate.

        9.5 Any of the New Certificates and any funds held by the Exchange Agent
for payment in cash for fractional shares that remain unclaimed for twelve
months after the Effective Time shall be returned or paid to Umpqua. Any holders
of VRB Common Stock who have not theretofore complied with this Section 9 shall
thereafter look to Umpqua only for payment of the Merger consideration and
unpaid dividends and distributions (if any) on Umpqua Common Stock deliverable
in respect of VRB Common Stock such shareholders hold as determined pursuant to
this Agreement, in each case without any interest thereon.

        10. DISSENTERS' RIGHTS. The shareholders of Umpqua and VRB have no
rights under Oregon law to dissent from this Plan of Merger.

        11. SHAREHOLDER APPROVAL. This Plan of Merger has been ratified and
approved by the shareholders of Umpqua and VRB at meetings called and held in
accordance with the applicable provisions of law and their respective Articles
of Incorporation and Bylaws. Each of Umpqua and VRB have procured all other
consents and approvals, taken all other actions, and satisfied all other
requirements prescribed by law or otherwise, necessary for consummation of the
Merger on the terms herein provided.

        12. CONDITIONS TO THE MERGER. All conditions precedent to the
effectiveness of this Plan of Merger as set forth in the Reorganization
Agreement has been satisfied or waived.

to be executed by their duly authorized officers as of the date first above
written.

(Reconfirmed October __, 2000)

Board of Directors
Umpqua Holdings Corporation
445 S.E. Main Street
Roseburg, OR 97470

Ladies and Gentlemen:

        We understand that Umpqua Holdings Corporation ("Umpqua") and VRB
Bancorp ("VRB") entered into an Agreement and Plan of Reorganization dated as of
August 14, 2000 (the "Agreement"), pursuant to which VRB will be merged with and
into Umpqua (the "Merger"). Under the terms of the Agreement, upon consummation
of the Merger, each share of VRB common stock, no par value, issued and
outstanding immediately prior to the effective time of the Merger, other than
certain shares specified in the Agreement, will be converted into the right to
receive 0.8135 shares (the "Exchange Ratio") of Umpqua common stock, no par
value. The terms and conditions of the Merger are more fully set forth in the
Agreement. You have requested our opinion as to the fairness, from a financial
point of view, of the Exchange Ratio to the holders of shares of Umpqua common
stock.

        Ragen MacKenzie Incorporated, as part of its investment banking
business, is customarily engaged in the valuation of businesses, including
financial institutions, and their securities in connection with mergers and
acquisitions, negotiated underwritings, secondary distributions of listed and
unlisted securities, and other corporate transactions. In connection with
rendering this fairness opinion, Ragen MacKenzie reviewed, among other things:
(i) the Agreement and exhibits thereto; (iii) certain publicly available
financial statements of Umpqua and other historical financial information
provided by Umpqua that we deemed relevant; (iv) certain publicly available
financial statements of VRB and other historical financial information provided
by VRB that we deemed relevant; (v) certain financial analyses and forecasts of
Umpqua prepared by and reviewed with management of Umpqua and the views of
senior management of Umpqua regarding Umpqua's past and current business
operations, results thereof, financial condition and future prospects; (vi)
certain financial analyses and forecasts of VRB prepared by and reviewed with
management of VRB and the views of senior management of VRB regarding VRB's past
and current business operations, results thereof, financial condition and future
prospects; (vii) the pro forma impact of the Merger; (viii) the publicly
reported historical price and trading activity for Umpqua's and VRB's common
stock, including a comparison of certain financial and stock market information
for Umpqua and VRB with similar publicly available information for certain other
publicly traded companies; (ix) the financial terms of recent business
combinations in the banking industry deemed relevant to our analysis; (x) the
current market environment generally and the banking environment


                                     App-72
<PAGE>   239

in particular; and (xi) such other information, financial studies, analyses and
investigations and financial, economic and market criteria as we considered
relevant.

        In preparing its fairness opinion, Ragen MacKenzie has assumed and
relied upon, without independent verification, the accuracy and completeness of
all the financial information, analyses and other information that was publicly
available or otherwise furnished to, reviewed by or discussed with us, and we do
not assume any responsibility or liability therefor. We did not make an
independent evaluation or appraisal of the specific assets, the collateral
securing assets or the liabilities (contingent or otherwise) of Umpqua or VRB or
any of their subsidiaries, or the collectibility of any such assets, nor have we
been furnished with any such evaluations or appraisals. With respect to the
financial projections reviewed with management, we have assumed that they have
been reasonably prepared on bases reflecting the best currently available
estimates and judgments of the respective managements of the respective future
financial performances of Umpqua and VRB and that such performances will be
achieved, and we express no opinion as to such financial projections or the
assumptions on which they are based. We have also assumed that there has been no
material change in Umpqua's or VRB's assets, results of operations, financial
condition, business or prospects since the date of the last financial statements
made available to us. We have assumed in all respects material to our analysis
that Umpqua and VRB will remain as going concerns for all periods relevant to
our analyses, that the Merger will be accounted for as a pooling of interests,
that all of the representations and warranties contained in the Agreement and
all related agreements are true and correct, that each party to such agreements
will perform all of the covenants required to be performed by such party under
such agreements and that the conditions precedent in the Agreement are not
waived.

        Our opinion is necessarily based on economic, market and other
conditions as in effect on, and the information made available to us as of, the
date hereof. Events occurring after the date hereof could materially affect this
opinion. We have not undertaken to update, revise or reaffirm this opinion or
otherwise comment upon events occurring after the date hereof. We are expressing
no opinion herein as to what the value of Umpqua's common stock will be when
issued to VRB's shareholders pursuant to the Agreement or the prices at which
Umpqua' or VRB's common stock will trade at any time.

        We have acted as Umpqua's financial advisor in connection with the
Merger and will receive a fee for our services, a significant portion of which
is contingent upon consummation of the Merger. In the past, we have also
provided, and may in the future provide, certain other investment banking
services for Umpqua and have received, and will receive, compensation for such
services.

        In the ordinary course of our business, we may actively trade debt and
equity securities of Umpqua and VRB for our own account and for the accounts of
our customers and, accordingly, may at any time hold a long or short position in
such securities.

        This fairness opinion is directed to the Board of Directors of Umpqua in
connection with its consideration of the Merger and does not constitute a
recommendation to any stockholder of Umpqua as to how such stockholder should
vote at any meeting of stockholders called to consider and vote upon the Merger.
Our opinion is not to be quoted or referred to, in whole or in part, in a


                                     App-73
<PAGE>   240

registration statement, prospectus, proxy statement or in any other document,
nor shall this opinion be used for any other purposes, without Ragen MacKenzie's
prior written consent; provided, however, that we hereby consent to the
inclusion of this opinion as an appendix to Umpqua' and VRB's Joint Proxy
Materials to be distributed to their shareholders and to the references to this
opinion therein.

        Based upon and subject to the foregoing, it is our opinion, as of the
date hereof, that the Exchange Ratio is fair, from a financial point of view, to
the holders of shares of Umpqua common stock.

Very truly yours,


RAGEN MACKENZIE INCORPORATED

August 14, 2000
(Reconfirmed October __, 2000)

Board of Directors
VRB Bancorp
110 Pine Street
Rogue River, Oregon 97537

Ladies & Gentlemen:

You have asked D.A. Davidson & Co. ("Davidson") to provide this written opinion
as to the fairness to the holders of the outstanding shares of common stock of
VRB Bancorp ("VRB"), Rogue River, Oregon, from a financial point of view, of the
exchange ratio to be used for the purpose of converting shares of VRB common
stock into shares of common stock of Umpqua Holdings Corporation ("Umpqua"),
Roseburg, Oregon in the proposed merger of equals between VRB and Umpqua.

We reviewed the August 11, 2000 draft of the Agreement and Plan of Merger to be
dated as of August 14, 2000, (the "Agreement"). The Agreement states that VRB
will merge into Umpqua, which will be the surviving corporation. One hundred
percent of the outstanding common stock shares of VRB will be converted into
shares of common stock of Umpqua according to the exchange ratio specified in
the Agreement.

Davidson, as part of its investment banking business, is engaged in the
valuation of banking and other 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. We make a market in the
common stock of VRB but do not publish a research recommendation on the stock.
We do not make a market in nor publish a research recommendation on the stock of
Umpqua. Davidson will receive a fee for providing our opinion to you.

In connection with our opinion, we have, among other things:

    1.  Evaluated financial and operating information relating to VRB and Umpqua
        including without limitation, financial reports of both companies filed
        with the SEC and other regulatory agencies for the fiscal years ending
        December 31, 1998 and 1999 and for the periods ending March 31, 2000 and
        June 30, 2000, and other internal operating reports and analyses, asset
        quality evaluations and related information;

    2.  Conducted conversations with executive management regarding recent and
        projected financial performance of both;


                                     App-75
<PAGE>   242

    3.  Compared operating results of both with those of certain other banks in
        the United States, which have recently engaged in a merger of equals
        transaction;

    4.  Compared the relative contributions of assets, liabilities, income and
        expenses to the resulting company in the merger to those of certain
        other banks in the United States, which have recently engaged in a
        merger of equals transaction;

    5.  Analyzed the pro-forma results that the resulting company could produce
        through 2002 based upon assumptions provided by management; and

    6. Performed such other analyses, as we deemed appropriate.

We have assumed and relied upon, without independent verification, the accuracy
and completeness of the information provided to us by both companies for the
purpose of this opinion. Additionally, where appropriate, we have relied upon
publicly available information that we believe to be reliable, accurate and
complete; however, we cannot guarantee the reliability, accuracy or completeness
of any such publicly available information. We have also assumed the
reasonableness of and relied upon the estimates and judgments of each company's
management as to the resulting company's future business and financial
prospects.

We have not made an independent evaluation of the assets or liabilities of VRB
or Umpqua, nor has either company furnished us with such appraisals. We are not
experts in the evaluation of loan portfolios for the purposes of assessing the
adequacy of the allowance for loan and lease losses and have assumed that such
allowances for each of the companies are, in the aggregate, adequate to cover
such losses.

Our opinion is necessarily based upon economic, market and other conditions as
in effect on, and the information made available to us as of the August 14,
2000. Events occurring after August 14, 2000 could materially affect the
assumptions used in preparing this opinion.

The preparation of an opinion involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
those methods to the particular circumstances. Consequently, this opinion is not
readily susceptible to partial analysis of summary description. Moreover, the
evaluation of fairness, from a financial point of view, of the Exchange Ratio is
to some extent subjective, based on our experience and judgment, and not merely,
the result of mathematical analysis of financial data. Accordingly, not
withstanding the separate factors summarized above, we believe that our analyses
must be considered as a whole and that selecting portions of our analysis and of
the factors considered by us, without considering all analyses and factors,
could create an incomplete view of the evaluation process underlying our
opinion.

Our opinion is limited to the fairness of the Exchange Ratio, from a financial
point of view, to the holders of VRB common stock. This letter is intended for
the benefit and sole use of the VRB Board of Directors and may not be used for
any other purpose. Although consent is given to include the opinion in VRB's
proxy statement, the opinion is not a recommendation to any VRB


                                     App-76
<PAGE>   243

common stockholder as to how such holder should vote with respect to the Merger.
Our opinion does not address the underlying business decision to proceed with
the Merger.

Based upon the foregoing and other such matters we have deemed relevant, it is
our opinion, as of August 14, 2000 that the exchange ratio of 0.8135 which will
be used to convert VRB common shares into shares of Umpqua common stock as
specified in the Agreement is fair, from a financial point of view, to the
common stock holders of VRB.

Very truly yours,

               trades occurred;

           2)  If the Common Stock is not traded on a national securities
               exchange or on Nasdaq but bid and asked prices are regularly
               quoted on the OTC Bulletin Board Service, by the National
               Quotation Bureau or any other comparable service, the average
               between the highest bid and lowest asked prices per share of
               Common Stock as reported by such service for such date or, if
               such date was not a business day, on the preceding business day;
               or

           3)  If there is no public trading of the Common Stock within the
               terms of subparagraphs 1 or 2 of this subsection, the price per a
               share of Common Stock, as determined by the Committee in its sole
               discretion.

        (m) "Incentive Stock Option" means an option to purchase shares of
            Common Stock that the Committee indicates is intended to qualify as
            an incentive stock option within the meaning of Section 422 of the
            Internal Revenue Code and is granted under Article VI of this Plan.

        (n) "Nonqualified Stock Option" means an option to purchase shares of
            Common Stock that the Committee either indicates is intended to be a
            nonqualified stock option or indicates is not intended to qualify as
            an incentive stock option within the meaning of Section 422 of the
            Internal Revenue Code and is granted under Article VII of this Plan.

        (o) "Optionee" means any individual who is granted either an Incentive
            Stock Option or a Nonqualified Stock Option under this Plan.

        (p) "Reserved Shares" means the number of shares of Common Stock
            reserved for issuance pursuant to Awards under this Plan as provided
            in Section 3.1 of Article III but in no event shall the sum of (i)
            the number Reserved Shares from time to time and (ii) the number of
            shares subject to options outstanding as of the Effective Date,
            exceed 10% of the total shares of Common Stock issued and
            outstanding, from time to time.


                                     App-79
<PAGE>   246

        (q) "Securities Act" means the Securities Act of 1933, as amended.

        (r) "Significant Shareholder" means any person who owns stock possessing
            more than ten percent (10%) of the total combined voting power of
            all classes of stock of the Company or any parent or subsidiary of
            the Company. For purposes of this definition a person shall be
            considered as owning all stock owned, directly or indirectly by or
            for such person's brothers and sisters, spouse, ancestors and lineal
            descendants. In addition, stock owned, directly or indirectly, by or
            for a corporation, partnership, estate or trust shall be considered
            as being owned proportionately by or for its shareholders, partners
            or beneficiaries to the extent required by Section 422 of the
            Internal Revenue Code.

                                   ARTICLE III
                            STOCK SUBJECT TO THE PLAN

        3.1 AGGREGATE NUMBER OF RESERVED SHARES. Subject to adjustment in
accordance with Section 9.1, the total number of shares of Common Stock reserved
for issuance pursuant to all Awards under this Plan is initially established at
1,000,000 shares.

        3.2 NUMBER OF AVAILABLE SHARES. At any point in time, the number of
Available Shares shall be the number of Reserved Shares at such time minus:

           (a) the number of shares of Common Stock issued upon the exercise of
               Incentive Stock Options and Nonqualified Stock Options prior to
               such time; and
           (b) the number of shares covered by Incentive Stock Options and
               Nonqualified Stock Options that have been granted and that have
               not yet expired, been terminated or been cancelled to the extent
               that such options have not been exercised at such time.

As a result of the foregoing, if an Incentive Stock Option or Nonqualified Stock
Option expires, terminates or is cancelled for any reason without having been
exercised in full, the shares of Common Stock covered by such option that were
not purchased through the exercise of such option will be added back to the
Available Shares. However, shares of Common Stock used by an Optionee to satisfy
withholding obligations upon the exercise of a Nonqualified Stock Option shall
nonetheless, for purposes of this Plan, be considered as having been issued upon
the exercise of such option.

        3.3 RESERVATION OF SHARES. Available Shares shall consist of authorized
but unissued shares of Common Stock of the Company. The Company will, at all
times, reserve for issuance shares of Common Stock equal to the sum of (i) the
number of shares covered by Incentive Stock Options and Nonqualified Stock
Options that have been granted and which have not yet expired, been terminated
or been cancelled to the extent that such options have not been exercised at
such time and (ii) the number of Available Shares.

        3.4 ANNUAL LIMIT ON NUMBER OF SHARES TO ANY ONE PERSON. No person will
be eligible to receive Awards under this Plan which, in aggregate, exceed 75,000
shares in any


                                     App-80
<PAGE>   247

calendar year except in connection with the hiring or commencement of services
from such person in which case such limit shall be 100,000 shares during such
calendar year.

                                   ARTICLE IV
                      COMMENCEMENT AND DURATION OF THE PLAN

        4.1 EFFECTIVE DATE OF THE PLAN. This Plan will be effective as of the
Effective Date, subject to the provisions of Section 4.2.

        4.2 SHAREHOLDER APPROVAL OF THE PLAN. This Plan will be submitted for
the approval of the shareholders of the Company within twelve (12) months of the
Effective Date. This Plan will be deemed approved by the shareholders if
approved by a majority of the votes cast at a duly held meeting of the Company's
shareholders at which a quorum is present in person or by proxy. Awards may be
made under this Plan prior to such shareholder approval provided that such
Awards are conditioned upon such approval and state by their terms that they
will be null and void if such shareholder approval is not obtained.

        4.3 TERMINATION OF THE PLAN. This Plan will terminate ten years from the
Effective Date. In addition, the Board of Directors will have the right to
suspend or terminate this Plan at any time. Any termination of this Plan will
not affect the exercisability of any Incentive Stock Options or Nonqualified
Stock Options granted under this Plan prior to such termination. Termination of
the Plan will not terminate or otherwise affect any Incentive Option Agreement
(as defined in Section 6.1), Nonqualified Option Agreement (as defined in
Section 7.1) or Restricted Stock Agreement (as defined in Section 9.1) then in
effect.

                                    ARTICLE V
                           ADMINISTRATION OF THE PLAN

        Subject to the provisions of this Plan and any additional terms or
conditions which may, from time to time, be imposed by the Board of Directors,
the Committee will administer this Plan and will have the authority, in its sole
discretion, to grant Incentive Stock Options and to grant Nonqualified Stock
Options in accordance with Articles VI and VII, respectively. The Committee may,
from time to time, adopt rules and regulations relating to the administration of
this Plan and may, but is not required to, seek the advice of legal, tax,
accounting and compensation advisors. Decisions of the Committee with respect to
the administration of this Plan, the interpretation or construction of this Plan
or the interpretation or construction of any written agreement evidencing an
Award will be final and conclusive, subject only to review by the full Board of
Directors. The Committee may correct any defect, supply any omission or
reconcile any inconsistency in this Plan or in any agreement evidencing an Award
in the manner and to the extent it deems appropriate.

        The Board of Directors shall appoint the members of the Committee, which
shall consist of at least two directors from the Board of Directors. For
purposes of this paragraph, directors who are not "outside directors" as such
term is defined in Treasury Regulation Section 1.162-27(e)(3) and directors who
are not "non-employee directors" as such term is defined in Rule 16b-3 issued by
the Securities and Exchange Commission under Section 16 of the Securities
Exchange Act of 1934, as amended, ("Rule 16b-3") shall be referred to as
"disqualified directors." Disqualified directors may serve on


                                     App-81
<PAGE>   248

the Committee. However, disqualified directors shall be deemed (notwithstanding
any statement to the contrary which may be contained in minutes of a meeting of
the Committee) to have abstained from any action requiring under Section 162(m)
of the Internal Revenue Code the approval of a committee consisting solely of
outside directors or from any action requiring under Rule 16b-3 the approval of
a committee consisting solely of non-employee directors. The assent of any such
disqualified director shall be ignored for purposes of determining whether or
not any such actions were approved by the Committee. If the Committee proposes
to take an action by unanimous consent in lieu of a meeting and such action
would require under Section 162(m) of the Internal Revenue Code the approval of
a committee consisting solely of outside directors or such action would require
under Rule 16b-3 the approval of a committee consisting solely of non-employee
directors, the disqualified director shall, for purposes of such consent, be
deemed to not be a member of the Committee.

        If no Committee is appointed, the Board of Directors shall act as the
Committee and will have all the powers, duties and responsibilities of the
Committee as set forth in this Plan. In addition, the Board of Directors may at
any time by resolution abolish the Committee and assume the duties and
responsibilities of the Committee.

                                   ARTICLE VI
                   INCENTIVE STOCK OPTION TERMS AND CONDITIONS

        Incentive Stock Options may be granted under this Plan in accordance
with the following terms and conditions.

        6.1 REQUIREMENT FOR A WRITTEN INCENTIVE STOCK OPTION AGREEMENT. Each
Incentive Stock Option will be evidenced by a written option agreement
("Incentive Stock Option Agreement"). The Committee will determine from time to
time the form of Incentive Stock Option Agreement to be used. The terms of the
Incentive Stock Option Agreement must be consistent with this Plan and any
inconsistencies will be resolved in accordance with the terms and conditions
specified in this Plan. Except as otherwise required by this Section 6, the
terms and conditions of each Incentive Stock Option do not need to be identical.

        6.2 WHO MAY BE GRANTED AN INCENTIVE STOCK OPTION. An Incentive Stock
Option may be granted to any Employee who, in the judgment of the Committee, has
performed or will perform services of importance to the Company in the
management, operation and development of the business of the Company or of one
or more of its subsidiaries. The Committee, in its sole discretion, shall
determine when and to which Employees Incentive Stock Options are granted under
this Plan.

        6.3 NUMBER OF SHARES COVERED BY AN INCENTIVE STOCK OPTION. The
Committee, in its sole discretion, shall determine the number of shares of
Common Stock covered by each Incentive Stock Option granted under this Plan. The
number of shares covered by each Incentive Stock Option shall be specified in
the Incentive Stock Option Agreement evidencing such option.


                                     App-82
<PAGE>   249

        6.4 VESTING SCHEDULE UNDER AN INCENTIVE STOCK OPTION. The Committee, in
its sole discretion, shall determine whether an Incentive Stock Option is
immediately exercisable as to all of the shares of Common Stock covered by such
option or whether it is only exercisable in accordance with a vesting schedule
as determined by the Committee, in its sole discretion. The vesting terms and
conditions, if any, of each Incentive Stock Option as determined by the
Committee shall be specified in the Incentive Stock Option Agreement evidencing
such option. Notwithstanding the foregoing, to the extent that an Incentive
Stock Option (together with other incentive stock options within the meaning of
Section 422 of the Internal Revenue Code held by such Optionee with an equal or
lower exercise price per share) purports to become exercisable for the first
time during any calendar year as to shares of Common Stock with a Fair Market
Value (determined at the time of grant) in excess of $100,000, such excess
shares shall be considered to be covered by a nonqualified stock option and not
an incentive stock option within the meaning of Section 422 of the Internal
Revenue Code. Any Incentive Stock Option granted under this Plan that was not
either approved by (i) a committee of non-employee directors within the
requirements of Rule 16b-3 or (ii) the full board of directors of the Company,
shall, notwithstanding Section 9.2 of this Plan or the terms set forth in the
Incentive Stock Option Agreement not be exercisable until at least six months
after the date of such grant.

        6.5 EXERCISE PRICE OF AN INCENTIVE STOCK OPTION. The Exercise Price
under each Incentive Stock Option will be at least 100% of the Fair Market Value
of a share of Common Stock as of the date on which the Incentive Stock Option
was granted. However, the Exercise Price under each Incentive Stock Option
granted to an Optionee who is a Significant Shareholder will be at least 110% of
the Fair Market Value of a share of Common Stock as of the date on which the
Incentive Stock Option was granted.

        6.6 DURATION OF AN INCENTIVE STOCK OPTION--GENERALLY. The Committee will
determine, in its sole discretion, the term of each Incentive Stock Option
provided that such term will not exceed 10 years from the date on which such
option was granted. However, the term of each Incentive Stock Option granted to
an Optionee who is a Significant Shareholder will not exceed 5 years from the
date on which such option was granted. The term of each Incentive Stock Option
shall be set forth in the written option agreement evidencing such option. The
Optionee shall have no further right to exercise an Incentive Stock Option
following the expiration of such term.

        6.7 THE EFFECT OF TERMINATION OF THE OPTIONEE'S EMPLOYMENT ON THE TERM
OF AN INCENTIVE STOCK OPTION. If an Optionee, while possessing an Incentive
Stock Option that has not expired or been fully exercised, ceases to be an
Employee of the Company for any reason other than as a result of the death or
disability of the Optionee (as provided for in Section 6.8 and 6.9,
respectively), the Incentive Stock Option may be exercised, to the extent not
previously exercised and subject to any vesting provisions contained in the
Incentive Stock Option Agreement, at any time within 30 days following the date
the Optionee ceased to be an Employee of the Company except that this provision
will not extend the time within which an Incentive Stock Option may be exercised
beyond the expiration of the term of such option. The Incentive Stock Option
Agreement may, in the discretion of the Committee, provide that if the
Optionee's employment is terminated by the Company for cause, as determined by
the Company's President or Board of Directors in their reasonable discretion,
the Incentive Stock Option will terminate immediately upon the Company's notice
to the Optionee of such termination.


                                     App-83
<PAGE>   250

        6.8 THE EFFECT OF THE DEATH OF AN OPTIONEE ON THE TERM OF AN INCENTIVE
STOCK OPTION. If an Optionee, while possessing an Incentive Stock Option that
has not expired or been fully exercised, ceases to be an Employee of the Company
as a result of the death of the Optionee, the Incentive Stock Option may be
exercised, to the extent not previously exercised and subject to any vesting
provisions contained in the Incentive Stock Option Agreement, at any time within
12 months following the date of the Optionee's death except that this provision
will not extend the time within which an Incentive Stock Option may be exercised
beyond the expiration of the term of such option.

        6.9 THE EFFECT OF THE DISABILITY OF AN OPTIONEE ON THE TERM OF AN
INCENTIVE STOCK OPTION. If an Optionee, while possessing an Incentive Stock
Option that has not expired or been fully exercised, ceases to be an Employee of
the Company as a result of the Optionee becoming Disabled, the Incentive Stock
Option may be exercised, to the extent not previously exercised and subject to
any vesting provisions contained in the Incentive Stock Option Agreement, at any
time within 12 months following the date of the Optionee becoming Disabled
except that this provision will not extend the time within which an Incentive
Stock Option may be exercised beyond the expiration of the term of such option.

        6.10 TRANSFERABILITY. No Incentive Stock Option may be transferred by
the Optionee other than by will or the laws of descent and distribution upon the
death of the Optionee.

        6.11 TAX TREATMENT AND SAVINGS CLAUSE. Nothing contained in this Plan,
any Incentive Stock Option Agreement, any document provided by the Company to an
Optionee or any statement made by or on behalf of the Company shall constitute a
representation or warranty of the tax treatment of any option or that such
option shall qualify as an incentive stock option under Section 422 of the
Internal Revenue Code. Any option that is designated as an Incentive Stock
Option but which, either in whole or in part, fails for any reason to qualify as
an incentive stock option within the meaning of Section 422 of the Internal
Revenue Code or which fails to satisfy requirements under this Plan which apply
only to Incentive Stock Options shall be treated as an incentive stock option to
the fullest extent permitted under Section 422 of the Internal Revenue Code and
this Plan and shall otherwise, notwithstanding such designation, be treated as a
Nonqualified Stock Option under this Plan.

                                   ARTICLE VII
                 NONQUALIFIED STOCK OPTION TERMS AND CONDITIONS

        Nonqualified Stock Options may be granted under this Plan in accordance
with the following terms and conditions.


                                     App-84
<PAGE>   251

        7.1 REQUIREMENT FOR A WRITTEN NONQUALIFIED STOCK OPTION AGREEMENT. Each
Nonqualified Stock Option will be evidenced by a written option agreement
("Nonqualified Stock Option Agreement"). The Committee will determine from
time-to-time the form of Nonqualified Stock Option Agreement to be used under
this Plan. The terms of the Nonqualified Stock Option Agreement must be
consistent with this Plan and any inconsistencies will be resolved in accordance
with the terms and conditions specified in this Plan. Except as otherwise
required by this Section 7, the terms and conditions of each Nonqualified Stock
Option do not need to be identical.

        7.2 WHO MAY BE GRANTED A NONQUALIFIED STOCK OPTION. A Nonqualified Stock
Option may be granted to any Employee, any director of the Company and any other
individual who, in the judgment of the Committee, has performed or will perform
services of importance to the Company in the management, operation and
development of the business of the Company or of one or more of its
subsidiaries. The Committee, in its sole discretion, shall determine when and to
whom Nonqualified Stock Options are granted under this Plan.

        7.3 NUMBER OF SHARES COVERED BY A NONQUALIFIED STOCK OPTION. The
Committee, in its sole discretion, shall determine the number of shares of
Common Stock covered by each Nonqualified Stock Option granted under this Plan.
The number of shares covered by each Nonqualified Stock Option shall be
specified in the Nonqualified Stock Option Agreement evidencing such option.

        7.4 VESTING SCHEDULE UNDER A NONQUALIFIED STOCK OPTION. The Committee,
in its sole discretion, shall determine whether a Nonqualified Stock Option is
immediately exercisable as to all of the shares of Common Stock covered by such
option or whether it is only exercisable in accordance with a vesting schedule
as determined by the Committee, in its sole discretion. The vesting terms and
conditions, if any, of each Nonqualified Stock Option as determined by the
Committee shall be specified in the Nonqualified Stock Option Agreement
evidencing such option. Any Nonqualified Stock Option granted under this Plan
that was not either approved by (i) a committee of non-employee directors within
the requirements of Rule 16b-3 or (ii) the full board of directors of the
Company, shall, notwithstanding Section 9.2 of this Plan or the terms set forth
in the written option agreement not be exercisable until at least six months
after the date of such grant.

        7.5 EXERCISE PRICE OF A NONQUALIFIED STOCK OPTION. The Exercise Price
under each Nonqualified Stock Option will be at least 100% of the Fair Market
Value of a share of Common Stock as of the date on which the Nonqualified Stock
Option was granted. However, if it is subsequently determined that the Exercise
Price as stated in the Nonqualified Stock Option Agreement is less than 100% of
the Fair Market Value of a share of Common Stock as of the date on which an
option was granted, such fact will not invalidate a Nonqualified Stock Option.

        7.6 DURATION OF A NONQUALIFIED STOCK OPTION--GENERALLY. The Committee
will determine, in its sole discretion, the term of each Nonqualified Stock
Option provided that such term will not exceed 10 years from the date on which
such option was granted. The term of each Nonqualified Stock Option shall be set
forth in the Nonqualified Stock Option Agreement evidencing such option. The
Optionee shall have no further right to exercise a Nonqualified Stock Option
following the expiration of such term.


                                     App-85
<PAGE>   252

        7.7 THE EFFECT OF TERMINATION OF THE OPTIONEE'S EMPLOYMENT OR SERVICE AS
A DIRECTOR ON THE TERM OF A NONQUALIFIED STOCK OPTION. If an Optionee, while
possessing a Nonqualified Stock Option that has not expired or been fully
exercised, ceases to be an Employee of the Company (or, in the case of an
Optionee who is not an Employee but is a director of the Company, ceases to be a
director of the Company) for any reason other than as a result of the death or
disability of the Optionee (as provided for in Section 7.8 and 7.9,
respectively), the Nonqualified Stock Option may be exercised, to the extent not
previously exercised and subject to any vesting provisions contained in the
Nonqualified Stock Option Agreement, at any time within 30 days following the
date the Optionee ceased to be an Employee (or a director as the case may be) of
the Company except that this provision will not extend the time within which an
Nonqualified Stock Option may be exercised beyond the expiration of the term of
such option. The Nonqualified Stock Option Agreement may, in the discretion of
the Committee, provide that if the Optionee's employment is terminated by the
Company for cause, as determined by the Company's President or Board of
Directors in their reasonable discretion, the Nonqualified Stock Option will
terminate immediately upon the Company's notice to the Optionee of such
termination.

        7.8 THE EFFECT OF THE DEATH OF AN OPTIONEE ON THE TERM OF A NONQUALIFIED
STOCK OPTION. If an Optionee, while possessing a Nonqualified Stock Option that
has not expired or been fully exercised, ceases to be an Employee, ceases to
serve as a director of the Company or ceases to provide services to the Company
as a result of the Optionee's death, the Nonqualified Stock Option may be
exercised, to the extent not previously exercised and subject to any vesting
provisions contained in the Nonqualified Stock Option Agreement, at any time
within 12 months following the date of the Optionee's death except that this
provision will not extend the time within which a Nonqualified Stock Option may
be exercised beyond the expiration of the term of such option.

        7.9 THE EFFECT OF THE DISABILITY OF AN OPTIONEE ON THE TERM OF A
NONQUALIFIED STOCK OPTION. If an Optionee, while possessing a Nonqualified Stock
Option that has not expired or been fully exercised, ceases to be an Employee,
ceases to serve as a director of the Company or ceases to provide services to
the Company as a result of the Optionee becoming Disabled, the Nonqualified
Stock Option may be exercised, to the extent not previously exercised and
subject to any vesting provisions contained in the Nonqualified Stock Option
Agreement, at any time within 12 months following the date of the Optionee
becoming Disabled except that this provision will not extend the time within
which a Nonqualified Stock Option may be exercised beyond the expiration of the
term of such option.

        7.10 TRANSFERABILITY. The Committee may, in the Nonqualified Stock
Option Agreement evidencing any Nonqualified Stock Option, provide that such
Nonqualified Stock Option be transferred by gift to the Optionee's spouse,
children or a trust for the exclusive benefit of any combination of the
Optionee, the Optionee's spouse and the Optionee's children provided that any
transfer of a Nonqualified Option shall be conditioned upon the Optionee and the
transferee of such Nonqualified Stock Option executing and delivering to the
Company a form of Transfer/Assumption of Nonqualified Stock Option Agreement as
the Company may request. Notwithstanding any transfer of a Nonqualified Stock
Option, the Optionee shall remain liable to the Company for any income tax
withholding amounts which the Company is required to withhold at the time that
the transferred Nonqualified Stock Option is exercised. If the Nonqualified
Stock Option Agreement does not expressly provide that such Nonqualified Stock
Option is transferable, such Nonqualified Stock


                                     App-86
<PAGE>   253
Option may not be transferred by the Optionee, other than by will or the laws
of descent and distribution upon the death of the Optionee, without the prior
written consent of the Committee, which consent may be withheld in the
Committee's sole discretion.

                                  ARTICLE VIII
                     EXERCISE OF OPTIONS TO PURCHASE SHARES

        8.1 NOTICE OF EXERCISE. An Incentive Stock Option or Nonqualified Stock
Option may only be exercised by delivery to the Company of written notice signed
by the Optionee (or, in the case of exercise after death of the Optionee, by the
executor, administrator, heir or legatee of the Optionee, as the case may be)
directed to the President of the Company (or such other person as the Company
may designate) at the principal business office of the Company. The notice will
specify (i) the number of shares of Common Stock being purchased, (ii) the
method of payment of the Exercise Price, (iii) the method of payment of the Tax
Withholding if the option is a Nonqualified Stock Option, and (iv), unless a
registration under the Securities Act is in effect with respect to the Plan at
the time of such exercise, the notice of exercise shall contain such
representations as the Company determines to be necessary or appropriate in
order for the sale of shares of Common Stock being purchased pursuant to such
exercise to qualify for exemptions from registration under the Securities Act.

        8.2 PAYMENT OF EXERCISE PRICE. No shares of Common Stock will be issued
upon the exercise of any Incentive Stock Option or Nonqualified Stock Option
unless and until payment or adequate provision for payment of the Exercise Price
of such shares has been made in accordance with this subsection. Unless the
Committee, in its sole discretion, determines otherwise, payment of the Exercise
Price shall be in cash, by delivery of a full-recourse promissory note, by the
surrender of shares of Common Stock or other securities issued by the Company
(provided that such other securities have been held by the Optionee for at least
six months prior to the date on which the Option is being exercised) in
accordance with Section 8.4, or by any combination of the foregoing. The
Committee may, in its sole discretion, permit an Optionee to elect to pay the
Exercise Price by authorizing a duly registered and licensed broker-dealer to
sell the shares of Common Stock to be issued upon such exercise (or, at least, a
sufficient portion thereof) and instructing such broker-dealer to immediately
remit to the Company a sufficient portion of the proceeds from such sale to pay
the entire Exercise Price.

        8.3 PAYMENT OF TAX WITHHOLDING AMOUNTS. Unless the Committee, in its
sole discretion, determines otherwise, each Optionee must, upon the exercise of
a Nonqualified Stock Option (including Nonqualified Stock Options transferred by
the Optionee), either with the delivery of the notice of exercise or upon
notification of the amount due, pay to the Company or make adequate provision
for the payment of all amounts determined by the Company to be required to
satisfy applicable federal, state and local tax withholding requirements ("Tax
Withholding"). The Nonqualified Option Agreement may provide for, or the
Committee may allow in its sole discretion, the payment by the Optionee of the
Tax Withholding (i) in cash, (ii) by the Company withholding such amount from
other amounts payable by the Company to the Optionee, including salary, (iii) by
surrender of shares of Common Stock or other securities of the Company in
accordance with Section 8.4, (iv) by the application of shares that could be
received upon exercise


                                     App-87
<PAGE>   254

of the Nonqualified Stock Option in accordance with Section 8.4, or (v) any
combination of the foregoing.

        By receiving and exercising a Nonqualified Stock Option, the Optionee
shall be deemed to have consented to the Company withholding the amount of any
Tax Withholding from any amounts payable by the Company to the Optionee. The
Committee may, in its sole discretion, permit an Optionee to elect to pay the
Tax Withholding by authorizing a duly registered and licensed broker-dealer to
sell the shares to be issued upon such exercise (or, at least, a sufficient
portion thereof) and instructing such broker-dealer to immediately remit to the
Company a sufficient portion of the proceeds from such sale to pay the Tax
Withholding. No shares will be issued upon an exercise of a Nonqualified Stock
Option unless and until payment or adequate provision for payment of the Tax
Withholding has been made. If the Company determines that additional withholding
is or becomes required beyond any amount paid or provided for by the Optionee,
the Optionee will pay such additional amount to the Company immediately upon
demand by the Company. If the Optionee fails to pay the amount demanded, the
Company may withhold that amount from other amounts payable by the Company to
the Optionee, including salary.

        8.4 PAYMENT OF EXERCISE PRICE OR WITHHOLDING WITH OTHER SECURITIES. To
the extent permitted in Section 8.2 and Section 8.3 above, the Exercise Price
and Tax Withholding may be paid by the surrender of shares of Common Stock or
other securities of the Company. The notice of exercise shall indicate that
payment is being made by the surrender of shares of Common Stock or other
securities of the Company. Payment shall be made by either (i) delivering to the
Company the certificates or instruments representing such shares of Common Stock
or other securities, duly endorsed for transfer, or (ii) delivering to the
Company an attestation in such form as the Company may deem to be appropriate
with respect to the Optionee's ownership of the shares of Common Stock or other
securities of the Company. Shares of Common Stock shall, for purposes of this
Section 8 be valued at their Fair Market Value as of the last business day
preceding the day the Company receives the Optionee's notice of exercise. Other
securities of the Company shall, for purposes of this Section 8, be valued at
the publicly reported price, if any, for the last sale on the last business day
preceding the day the Company receives the Optionee's notice of exercise, or, if
there are no publicly reported prices of such other securities of the Company,
at the fair market value of such other securities as determined in good faith by
the Board of Directors. To the extent permitted in Section 8.3 above, Tax
Withholding may, if the Optionee so notifies the Company at the time of the
notice of exercise, be paid by the application of shares which could be received
upon exercise of any other stock option issued by the Company. This application
of shares shall be accomplished by crediting toward the Optionee's Tax
Withholding obligation the difference between the Fair Market Value of a share
of Common Stock and the Exercise Price of the stock option specified in the
Optionee's notice. Any such application shall be considered an exercise of the
other stock option to the extent that shares are so applied.

        8.5 COMPLIANCE WITH SECURITIES LAWS. No shares will be issued with
respect to the exercise of any Incentive Stock Option or Nonqualified Stock
Option unless the exercise and the issuance of the shares will comply with all
relevant provisions of law, including, without limitation, the Securities Act,
any registration under the Securities Act in effect with respect to the Plan,
all applicable state securities laws, the Securities Exchange Act of 1934, as
amended, the Internal Revenue Code, the respective rules and regulations
promulgated thereunder, and the


                                     App-88
<PAGE>   255

requirements of any stock exchange upon which the Common Stock may then be
listed, and will be further subject to the approval of counsel for the Company
with respect to such compliance. The Company will not be liable to any Optionee
or any other person for failure to issue shares upon the exercise of an option
where such failure is due to the inability of the Company to obtain all permits,
exemptions or approvals from regulatory authorities which are deemed by the
Company's counsel to be necessary. The Board may require any action or agreement
by an Optionee as may from time to time be necessary to comply with the federal
and state securities laws. The Company will not be obliged to prepare, file or
maintain a registration under the Securities Act with respect to the Plan or to
take any actions with respect to registration or qualification under any state
securities laws.

        8.6 ISSUANCE OF SHARES. Notwithstanding the good faith compliance by the
Optionee with all of the terms and conditions of an Incentive Option Agreement
or Nonqualified Option Agreement and with this Article VIII, the Optionee will
not become a shareholder and will have no rights as a shareholder with respect
to the shares covered by such option until the issuance of shares pursuant to
the exercise of such option is recorded on the stock transfer record of the
Company. Notwithstanding the foregoing, the Company shall not unreasonably delay
the issuance of a stock certificate and shall exercise reasonable efforts to
cause such stock certificate to be issued to the Optionee as soon as is
practicable after the compliance by the Optionee with all of the terms and
conditions of the Incentive Option Agreement or Nonqualified Option Agreement,
as the case may be, and with this Article VIII.

        8.7 NOTICE OF ANY DISQUALIFYING DISPOSITION AND PROVISION FOR TAX
WITHHOLDING. Any Optionee that exercises an Incentive Stock Option and then
makes a "disqualifying disposition" (as such term is defined under Section 422
of the Internal Revenue Code) of the shares so purchased, shall immediately
notify the Company in writing of such disqualifying disposition and shall pay or
make adequate provision for all Tax Withholding as if such Incentive Stock
Option was a Nonqualified Stock Option in accordance with Section 8.3.

                                   ARTICLE IX
                          CHANGES IN CAPITAL STRUCTURE

        9.1 ADJUSTMENTS OF NUMBER OF SHARES AND EXERCISE PRICE. Except as
provided in Section 9.2, if the outstanding shares of Common Stock are hereafter
increased, decreased, changed into or exchanged for a different number or kind
of shares of Common Stock or for other securities of the Company or of another
corporation, by reason of any reorganization, merger, consolidation,
reclassification, stock split-up, combination of shares of Common Stock, or
dividend payable in shares of Common Stock, the Committee will make such
adjustment as it deems appropriate in the number and kind of shares of Common
Stock or other securities covered by subsequent Awards. In addition, the
Committee will at such time make such adjustment in the number and kind of
shares of Common Stock or other securities covered by outstanding Incentive
Stock Options and outstanding Nonqualified Stock Options, as well as make an
adjustment in the Exercise Price under each option as the Committee deems
appropriate. Any determination by the Committee as to what adjustments may be
made, and the extent thereof, will be final, binding on all parties and
conclusive.

        9.2 ACCELERATION OF VESTING. In the event of any dissolution or
liquidation of the Company, or any merger or consolidation with one or more
corporations in which the Company is not the surviving entity, or in which the
security holders of the Company prior to such transaction do not receive in the
transaction securities with voting rights with respect to the election of
directors equal to 50% or more of the votes of all classes of outstanding
securities of the surviving corporation immediately after such transaction, each
outstanding Incentive Stock Option and each outstanding Nonqualified Stock
Option shall become immediately exercisable in its entirety, notwithstanding any
vesting schedule included in the respective Incentive Stock Option Agreement or
Nonqualified Stock Option Agreement, fifteen (15) days prior to such event and
shall, unless the event fails to occur, continue to be exercisable in such
manner for forty-five (45) days after such event, unless, as an expressed term
of such transaction, adequate provision is made for the continuation of the
rights of holders of such outstanding option after the consummation of such
transaction.

                                    ARTICLE X
                              UNDERWRITERS LOCK-UP

        Each written agreement evidencing an Award will specify that the
Optionee, by accepting the Award agrees that whenever the Company undertakes a
firmly underwritten public offering of its securities, the Optionee will, if
requested to do so by the managing underwriter in such offering, enter into an
agreement not to sell or dispose of any securities of the Company owned or
controlled by the Optionee provided that such restriction will not extend beyond
12 months from the effective date of the registration statement filed in
connection with such offering.

                                   ARTICLE XI
                                EMPLOYMENT RIGHTS

        Nothing in this Plan nor in any written agreement evidencing an Award
will confer upon any Optionee any right to continued employment with the Company
or to limit or affect in any way the right of the Company, in its sole
discretion, (a) to terminate the employment of such Optionee at any time, with
or without cause, (b) to change the duties of such Optionee, or (c) to increase
or decrease the compensation of the Optionee at any time. Unless the written
agreement evidencing an Award expressly provides otherwise, vesting under such
agreement shall be conditioned upon:

         1) for Employees of the Company, the continued employment of the
           Optionee;

         2) for independent contractors, the Optionee continuing to provide
           services to the Company on substantially the same terms and
           conditions as such services were provided at the time of the Award;
           or

         3) for directors who are not Employees, the Optionee continuing to
           serve as a director of the Company;

and nothing in this Plan shall be construed as creating a contractual or implied
right or covenant by the Company to continue such employment, service as an
independent contractor or service as a director.
