                               PROSPECTUS SUMMARY
 
     The following is a summary of information set forth in more detail
elsewhere in this Prospectus. Unless otherwise indicated, all information
contained in this Prospectus assumes that the Underwriters' over-allotment
option is not exercised. The number of shares and options outstanding and per
share amounts reflect the VRB's two-for-one stock split paid on September 17,
1997. References to "VRB" in this Prospectus mean VRB Bancorp and Valley of the
Rogue Bank, its subsidiary.
 
                                      VRB
 
OVERVIEW
 
     VRB is the largest community bank in southern Oregon, currently operating
nine full-service branches in the Rogue Valley. As of June 30, 1997, VRB had
assets of $179.6 million and deposits of $156.4 million. VRB has entered into an
agreement to acquire Colonial Banking Company ("Colonial"), which will add four
branches and $100.6 million in deposits, increasing VRB's market share to over
15% of commercial bank deposits in the Rogue Valley. See "Colonial Banking
Company Acquisition."
 
     VRB has delivered 29 consecutive years of profitability. During the most
recent five years, it has increased earnings by an average of 18% per year and
in each year has achieved a return on average equity greater than 16%. During
the same period, VRB's return on average assets has increased from 1.61% for
1992 to 1.99% for 1996. VRB has sustained a strong asset quality and
consistently performed in the top quartile when comparing its return on average
equity to its national peer group comprising over 900 banks with assets of
between $100 and $300 million and multiple branches located in metropolitan
areas.
 
     The consolidation of the banking industry in Oregon has had a positive
effect on VRB. Major regional banks have chosen to focus on larger metropolitan
markets and to de-emphasize personal service to achieve efficiencies. VRB
continues to introduce new products while maintaining the personal service and
local decision-making believed to be important to its customers. Its high level
of demand deposit accounts (29.7% of total deposits at June 30, 1997) has
significantly contributed to its consistently low cost of funds and high net
interest margin. VRB's growing base of core deposits confirms its belief that
its product delivery approach is attractive to a significant number of customers
in its market.
 
     VRB offers a broad range of commercial banking services, primarily to small
and medium-sized businesses, professionals, farmers and retail customers,
including commercial, real estate and agricultural loans, accounts receivable
and inventory financing, consumer installment loans, acceptance of deposits, and
personal savings and checking accounts. A majority of VRB's loans are commercial
loans collateralized with real estate.
 
BUSINESS STRATEGY
 
     VRB seeks significant growth in its earning assets while maintaining a high
return on equity. VRB believes that this objective can be achieved by continuing
to emphasize personalized, quality banking products and services to small and
medium-sized businesses, professionals and retail customers. VRB intends to
increase its market penetration in its existing markets and to expand into new
markets through acquisitions. VRB's strategy consists of the following:
 
     - Provide a full range of banking products and personalized service.  VRB
       believes offering products with a high level of personal service attracts
       and retains customers. Although many of its customers desire personal
       banking services, VRB also has made a commitment to provide new
       technological services to attract a broader customer base. These products
       and services include 24-hour telephone account access, a recently
       developed debit card program and an expanded ATM network.
 
     - Increase market share in existing markets.  VRB believes there is
       significant potential to increase its business with current customers and
       attract new customers in its existing market. Early in 1995, VRB embarked
       on a sales training program and in 1996 appointed a Corporate Sales
       Officer with
 
                                        3
<PAGE>   5
 
       responsibility for improving the business development skills of
       employees. VRB believes it can gain more customers within the Rogue
       Valley by continuing to distinguish itself from larger banks, all of
       which are headquartered in other states and have reduced personal service
       and transferred lending decisions away from local branches. As of June
       30, 1997, VRB's market share of commercial bank deposits in the Rogue
       Valley amounted to 9.3%, up from 7.7% on December 31, 1995. VRB believes
       this increase of over 20% in an eighteen month period is a direct result
       of its increased marketing efforts and validates VRB's belief that
       personalized service is important to a significant segment of the market.
       The addition of Colonial's deposits is expected to increase VRB's total
       market share to 15% of commercial bank deposits in the Rogue Valley.
 
     - Explore opportunistic acquisitions.  After the integration of Colonial,
       VRB intends to pursue acquisitions of other community banks. Although VRB
       is not currently engaged in any acquisition discussions, it believes that
       it will be able to supplement internal growth with complementary
       acquisitions.
 
     VRB Bancorp was organized in 1983 under Oregon law to become the holding
company for Valley of the Rogue Bank, an Oregon state-chartered bank that
commenced operations in 1968. VRB maintains its principal offices at 110 Pine
St., Rogue River, Oregon 97537, and its telephone number is 541-582-4561.

                                  RISK FACTORS
 
     This Prospectus contains certain forward-looking statements. Actual results
could differ materially from those projected in these forward-looking statements
as a result of certain of the risk factors set forth below and elsewhere in this
Prospectus. Prospective investors should carefully consider and evaluate all of
the information set forth in this Prospectus, including the Risk Factors set
forth below. This list of risk factors may not be exhaustive.
 
PENDING ACQUISITION OF COLONIAL BANKING COMPANY
 
     Although VRB has entered into an agreement which it expects will result in
the acquisition of Colonial, closing of the acquisition, anticipated in January
1998, is subject to the satisfaction of certain conditions of closing, including
regulatory and shareholder approval, and no assurance can be given the
acquisition will be consummated. See "Colonial Banking Company Acquisition."
 
     VRB believes that integration of the Colonial operations promptly following
the acquisition is critical to the success of the transaction. Although VRB has
completed four acquisitions, the most recent in 1993, Colonial is by far the
largest and the first to involve more than one banking office. No assurances can
be given that the integration of Colonial will be effected without loss of loan
or deposit customers or that problems in combining the operations of the two
banks will not be encountered.
 
     The principal use of the net proceeds from the Offering is to fund a
significant portion of the Colonial acquisition. Should the acquisition not
occur, VRB has no other current intended use or need for the offering proceeds
and, pending application of such proceeds, VRB's return on equity and earnings
per share would be adversely affected. No assurances can be given that such
funds could be efficiently deployed in the future. See "Use of Proceeds."
 
     The acquisition of Colonial for cash, even after the application of the net
proceeds of the Offering, will significantly reduce the capital-to-asset ratio
of VRB. Had the acquisition been completed as of June 30, 1997, and based upon
the anticipated net proceeds, VRB's total regulatory leverage ratio would have
been reduced from 11.91% to 10.76%. Although, the post-acquisition pro forma
ratio is substantially above the regulatory minimum of 4.0%, and VRB would still
qualify as "well capitalized," the reduction in the capital-to-asset ratio could
limit VRB's future growth or ability to pursue acquisition opportunities. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
EXPOSURE TO LOCAL ECONOMY
 
     VRB's performance is materially dependent upon and sensitive to the economy
of its market area consisting of the Rogue Valley in Jackson and Josephine
Counties of southern Oregon. Adverse economic developments may affect loan
demand and the collectibility of existing loans, and have a negative effect on
VRB's earnings and financial condition. The economy of the Rogue Valley depends
primarily on retail trade, tourism, government, services, agriculture, forest
products and other manufacturing industries. Particularly in the 1980's, VRB's
market area experienced high unemployment as a result of the reduction in forest
products manufacturing jobs. Subsequent developments have reduced the dependence
of the local economy on forest products manufacturing and have increased the
number of non-manufacturing jobs. There is no assurance that future economic
changes will not have a significant adverse effect on VRB. Although VRB has not
noticed any material decrease in lending activity, home sales in its market area
are down 26% during the first eight months of 1997 when compared to the
corresponding period in 1996. See "Business -- Market Area."
 
COMPETITION
 
     In recent years, competition for deposits and loans has intensified. A new
community bank has opened in Grants Pass and a second is being organized in
Medford. In addition, two super-regional banks in VRB's market area have been
acquired by even larger banks. Furthermore, competition from outside the
traditional banking system from investment banking firms, insurance companies
and related industries offering bank-like products has widened the competition
for deposits and loans. The banking industry in VRB's primary market
 
                                        7
<PAGE>   9
 
area is characterized by well-established branches of large banks which hold 75%
of local deposits. These institutions have competitive advantages over VRB in
that they have higher public visibility and are able to maintain advertising and
marketing activities on a much larger scale than VRB can economically sustain.
Single-borrower lending limits imposed by law are dependent on the capital of
the institution, giving branches of larger financial institutions a competitive
advantage with respect to loan applications which are in excess of VRB's legal
lending limits. See "Business -- Competition."
 
CREDIT RISK
 
     VRB, like other lenders, is subject to credit risk, which is the risk of
losing principal and interest due to a customer's failure to repay loans in
accordance with their terms. Although VRB has established lending criteria and
most loans are secured by collateral, a downturn in the economy or the real
estate market in the Rogue Valley or a rapid increase in interest rates could
have a negative effect on collateral values and borrowers' ability to repay. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
INTEREST RATE RISK
 
     VRB's earnings are largely derived from net interest income, which is
interest income and fees earned on loans and investment income, less interest
expense paid on deposits and other borrowings. Interest rates are highly
sensitive to many factors which are beyond the control of VRB's management,
including general economic conditions and the policies of various governmental
and regulatory authorities. As interest rates change, net interest income is
affected. With fixed rate assets (such as fixed rate loans) and liabilities
(such as certificates of deposit), the effect on net interest income depends on
the maturity of the asset or liability. Although the VRB strives to minimize
interest rate risk through asset/liability management policies, from time to
time maturities are not balanced. Although rates have remained stable in recent
periods, an unanticipated rapid decrease or increase in interest rates could
have an adverse effect on the spreads between the interest rates earned on
assets and the rates of interest paid on liabilities, and therefore on the level
of net interest income. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
DEPENDENCE ON KEY PERSONNEL
 
     VRB's success is dependent on the services of William A. Haden, President
and Chief Executive Officer, and Tom Anderson, Executive Vice President and
Chief Operating Officer. The loss of services of either of these executives, or
of certain other key officers, could adversely affect the Company. No assurance
can be given that replacement officers of comparable abilities could be found.
The Company does not maintain key person life insurance on these individuals.
See "Management."
 
OFFERING PRICE
 
     The price of the shares offered hereby will be determined by negotiations
between VRB and the representative of the Underwriters. There can be no
assurance that the market will sustain the offering price or that the offering
price necessarily indicates the fair value of the Common Stock. See
"Underwriting" and "Market Price of and Dividends on the Common Stock."
 
LIMITED MARKET FOR THE SHARES
 
     There is currently a limited market for VRB's shares. VRB's Common Stock
currently trades on the Bulletin Board Service of the Nasdaq Stock Market under
the symbol "VRB.A", but is not actively traded. VRB has applied for approval for
inclusion of the Common Stock in the National Market System on the effective
date of the Offering, but no assurances can be made that approval will be
obtained or that an active public market will develop or be maintained for the
shares. Moreover, the market price could be subject to significant fluctuations
in response to variations in VRB's quarterly operating results, general
conditions of the banking industry and other factors. In addition, the price of
the shares may fluctuate substantially due to the
 
                                        8
<PAGE>   10
 
effect of supply and demand in a limited market. Even if an active market for
the shares does develop, investors in this Offering cannot be assured of being
able to resell shares purchased in the Offering at or above the offering price.
See "Market Price of and Dividends on the Common Stock."
 
REGULATION
 
     VRB is subject to extensive regulations under federal and state laws. These
laws and regulations are intended to protect depositors, not shareholders. VRB
is subject to regulation and supervision by the FDIC which insures bank
deposits, and the Director of the Oregon Department of Consumer and Business
Services ("Oregon Director"). VRB is also subject to regulation and supervision
by the Board of Governors of the Federal Reserve. Federal and state regulations
puts banks at a competitive disadvantage compared to less regulated competitors
such as finance companies, credit unions, mortgage banking companies, and
leasing companies. Although the VRB has been able to compete effectively in its
market area in the past, there can be no assurance that it will be able to
continue to do so. Further, future changes in federal and state banking
regulations could adversely affect VRB's operating results and ability to
continue to effectively compete. See "Supervision and Regulation."

                      COLONIAL BANKING COMPANY ACQUISITION
 
ACQUISITION AGREEMENTS
 
     On July 24, 1997, VRB entered into a Stock Option Agreement with the
shareholders of Investors Banking Corporation ("IBC") which owns approximately
81% of the outstanding stock of Colonial. Pursuant to the Stock Option
Agreement, VRB has the right to acquire all of the outstanding shares of IBC. In
addition, VRB entered into a Plan of Merger, as of September 30, 1997, with
Colonial. Through a series of transactions (referred to herein as the
"Acquisition"), VRB intends to acquire all the banking operations of Colonial
which will be merged with the Bank. The aggregate cash purchase price to be paid
to the shareholders of IBC and Colonial is $15.7 million, and will be accounted
for by the purchase method of accounting. Under the purchase method of
accounting, assets and liabilities acquired or assumed will be restated at fair
value and the excess of the purchase price over net assets will be recorded as
goodwill. Anticipated goodwill of $10,202,000 will be capitalized when the
transaction is completed and amortized over 15 years. See "Unaudited Pro Forma
Combined Financial Statements."
 
BACKGROUND AND REASONS FOR ACQUISITION
 
     In June 1997, conversations were held between principals of VRB and
Colonial regarding Colonial's and IBC's willingness to entertain an acquisition
proposal. Management of VRB was familiar with Colonial's operations as
Colonial's banking offices are all within VRB's market area. Management believed
that the acquisition of Colonial would substantially enhance VRB's market
presence in the Rogue Valley and enhance shareholder value. Negotiations were
commenced and a non-binding Letter of Intent with Colonial and the Stock Option
Agreement with the IBC shareholders were executed effective July 23 and July 24,
1997, respectively. In the weeks that followed, VRB conducted due diligence with
respect to the business, operations and financial condition of Colonial and
negotiated the terms of the Plan of Merger.
 
COLONIAL BANKING COMPANY
 
     Colonial is an Oregon state-chartered bank organized in 1978. Colonial,
headquartered in Grants Pass, Oregon had $107.9 million in deposits at June 30,
1997, and operates five banking offices, two in Grants Pass and one each in
Medford, Merlin and Rogue River, Oregon. In addition to these banking offices,
Colonial has a loan production office located in Portland, Oregon. The loans
generated by this office are geographically dispersed throughout the Portland
metropolitan area and the state of Oregon which would lessen VRB's exposure to
the economic conditions of its current market area. Further, VRB's
loan-to-deposit ratio of 69.0% at June 30, 1997, would permit an increase in
loans without causing liquidity concerns and should enhance earnings as funds
currently invested in lower yielding securities are redeployed in higher
yielding loans.
 
     In recent years, Colonial has experienced substantial growth in deposits,
loans and income. The following table sets forth certain information regarding
Colonial at the date of or for the periods indicated.

</TABLE>
 
     The key contribution to the recent growth in loans was the opening of the
loan production office in Portland, Oregon in early 1996. This office generated
approximately 56% of Colonial's new loans in 1996 and 72% during the first six
months of 1997. In addition to substantially increasing loan totals and interest
income
 
                                       10
<PAGE>   12
 
for Colonial, the loans have contributed significantly to Colonial's fee income
for each period. The senior loan officers that manage Colonial's Portland loan
production office are not under long term contracts and have expressed a desire
to renegotiate the terms of their employment. There can be no assurance that VRB
will be able to these loan officers or attract replacements.
 
INTEGRATION OF COLONIAL OPERATIONS
 
     Completion of the Acquisition is anticipated in early 1998. Closing is
conditioned upon the satisfaction of certain representations, warranties and
covenants of Colonial and the receipt of regulatory and shareholder approval.
Although all approvals are expected to be received there can be no assurance
that the Acquisition will be consummated.
 
     Upon closing of the Acquisition, VRB will concentrate its efforts on
integrating the operations of Colonial. With the exception of the Rogue River
office of Colonial which will be consolidated with the head office of VRB, VRB
intends to continue to operate all of the offices of Colonial after the
Acquisition. As soon as practicable, VRB will institute its pricing policies for
deposits and loans and commence offering VRB's products to all Colonial
customers and endeavor to provide the same services throughout its entire branch
network. VRB has negotiated severance arrangements with the two senior executive
officers of Colonial. It does not intend to replace these officers, but
anticipates most other employees will continue to staff the Colonial offices
after the Acquisition. However, there can be no assurance that the integration
will be achieved in a timely and efficient manner.
 
     Colonial's cost of funds currently exceeds that of VRB. This higher cost is
a function of the mix of Colonial's deposit liabilities (which consists of a
higher percentage of interest bearing liabilities than that at VRB) and higher
rates paid on certain interest bearing deposits. As rates on deposits offered by
Colonial are reduced, it is anticipated that there will be some run-off of
deposit liabilities. VRB currently has substantial liquidity with over $40
million in investment securities at June 30, 1997, and believes that any
reduction in Colonial's deposits would be modest and would not adversely affect
either VRB's performance or materially reduce its liquidity.
 
                                USE OF PROCEEDS
 
     The net proceeds to VRB from the sale of the Common Stock offered, at an
assumed public offering price of $8.50 per share, are estimated to be $7,655,000
after deduction of underwriting discounts and commission and expenses payable by
VRB. Management expects to use the net proceeds of the Offering to fund a
significant portion of the Colonial Acquisition. In the unanticipated event the
Acquisition is not consummated, the net proceeds will be used for general
corporate purposes including other possible acquisitions. Prior to such use, the
net proceeds will be invested in short-term, investment grade securities. See
"Colonial Banking Company Acquisition."
 
     VRB currently exceeds all regulatory capital requirements and therefore is
not required to raise additional capital to comply with such requirements. After
the Acquisition, VRB expects to continue to exceed all regulatory capital
requirements.

     VRB Bancorp's ability to pay expenses and make cash dividend payments to
shareholders is dependent on earnings generated by its subsidiary Valley of the
Rogue Bank. Oregon and federal banking laws and regulations place restrictions
on the payment of dividends by a bank to its shareholders. See "Supervision and
Regulation -- Dividends." The Board of Directors' dividend policy is to review
VRB's financial performance, capital adequacy, regulatory compliance and cash
resources, and, if such review is favorable, to declare and pay a cash dividend
to shareholders annually. Although VRB expects to continue to pay cash
dividends, future dividends are subject to these limitations and to the
discretion of the Board of Directors, and could be reduced or eliminated.

                NOTES TO PROFORMA COMBINED FINANCIAL STATEMENTS
 
(A) In accordance with the Plan of Merger and pursuant to the Stock Option
    Agreement, VRB will exercise an option to purchase all of the shares of
    Investors Banking Corporation ("IBC"), the majority shareholder of Colonial,
    at an aggregate exercise price equal to $12.6 million determined by the
    product of $41.00 times the number of Colonial shares held by IBC. IBC will
    then liquidate into VRB and VRB will then acquire by merger the remaining
    common and preferred stock owned by the minority shareholders for $43.36 per
    share. The total purchase price of $15,708,000 is to be paid from the
    proceeds of this Offering, the liquidation of federal funds sold, and
    investment securities.
 
(B) In accordance with the Plan of Merger, prior to the acquisition, Colonial
    will cash out 47,599 common and preferred stock options at an amount equal
    to the difference between the weighted average exercise price of $10.61 and
    $43.36 per share, for a total payment of $1,029,000 net of tax effects.
    Colonial will also make severance payments to certain senior officers
    equivalent to one year's salary, or $115,000 net of estimated tax effects.
 
(C) The acquisition of Colonial will be accounted for using the purchase method
    of accounting under generally accepted accounting principles. Accordingly,
    the net assets of Colonial have been adjusted to their approximate fair
    values as of June 30, 1997 for a combined increase in assets of $85,000. IBC
    has no significant net assets other than its investments in Colonial.
 
(D) The amount represents the estimated proceeds from the sale of 1.0 million
    shares of VRB Common Stock assuming an Offering price of $8.50. Total
    proceeds have been reduced by 11%, representing the underwriting discounts
    and commissions and the estimated Offering expenses to be paid by VRB.
 
(E) The amount represents estimated loss of earnings from funds used to purchase
    Colonial, assuming such funds would have earned a rate equivalent to the
    average fed funds and investment securities rate of 5.5% earned by VRB
    during the period of the proforma income statements.
 
(F) The amount of estimated earnings realized on the net proceeds raised from
    the Offering assuming such funds will earn a rate equivalent to the average
    federal funds rate earned by VRB during the period of the proforma income
    statements (5.5%).
 
(G) The amount represents amortization of goodwill created as a result of the
    Colonial acquisition, assuming a 15 year amortization period.
 
(H) The estimated tax effect of such transactions as described in Notes (E) and
    (F) have been computed at VRB's effective tax rate of 34%. The amortization
    of goodwill (Note G) is not tax deductible.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following includes a discussion of certain significant business trends
and uncertainties as well as other forward-looking statements and is intended to
be read in conjunction with and is qualified in its entirety by reference to the
consolidated financial statements and accompanying notes included elsewhere in
this Prospectus. For a discussion of important factors that could cause actual
results to differ materially from the forward-looking statements, see "Risk
Factors".
 
FINANCIAL HIGHLIGHTS
 
     VRB Bancorp and its wholly owned subsidiary, Valley of the Rogue Bank, an
Oregon state chartered bank, serve customers in the Rogue Valley, consisting of
Jackson and Josephine Counties in Southern Oregon. VRB has had 29 consecutive
years of earnings, and for 13 of the last 14 years, earnings have increased.
Income for the six months ended June 30, 1997 was $1.8 million, compared to $1.6
million for the first six months of 1996. The Company reported net income of
$3.3 million for 1996, an increase of 13.8% over net income of $2.9 million in
1995. For the first six months of 1997, return on total average assets was 1.99%
and net interest margin was 6.80%, continuing years of strong performance in a
relatively stable interest rate environment.
 
RESULTS OF OPERATIONS
 
     For financial institutions, the primary component of earnings is net
interest income. Net interest income is the difference between interest income,
principally from loans and investment securities portfolios, and interest
expense, principally on customer deposits. Changes in net interest income result
from changes in "volume", "spread" and "margin." Volume refers to the dollar
level of interest-earning assets and interest-bearing liabilities. Spread refers
to the difference between the yield on interest-earning assets and the cost of
interest-bearing liabilities. Net Interest Margin is the ratio of net interest
income to total interest-earning assets and is influenced by the level and
relative mix of interest-earning assets and interest-bearing liabilities.

NET INTEREST INCOME
 
  For the Six Months Ended June 30, 1996 and 1997
 
     Net interest income for the six months ended June 30, 1997 was $5,244,000,
an increase of $724,000 over the corresponding period in 1996. The increase in
net interest income is primarily attributable to the increase in loan volume
which resulted in increased interest income of $856,000, an increase of 13.6%,
for the six months ended June 30, 1997 compared to the corresponding period in
1996. Interest expense increased $132,000 or 7.4% to $1.9 million for the first
six months of 1997 compared to $1.8 million for the corresponding period in
1996. The increase in interest expense was primarily a result of the growth of
interest-bearing checking and savings accounts.
 
     Total interest-earning assets averaged $161,462,000 for the six months
ended June 30, 1997, compared to $143,725,000 for the corresponding period in
1996. Most of the increase was due to an increase in loans. The average yield on
interest earning assets, when adjusted to reflect the tax benefits on certain
types of investments, increased to 9.16% during the first six months of 1997,
compared to 9.10% for the corresponding period 1996.
 
     Interest bearing liabilities averaged $100,618,000 and $112,326,000 during
the first six months of 1996 and 1997, respectively. The average cost of these
liabilities decreased in 1997 to 3.40% from 3.53% in 1996. The average cost of
total interest bearing liabilities and non-interest bearing deposits declined
from 2.57% during 1996 to 2.47% during 1997.
 
  For the Years Ended December 31, 1994, 1995 and 1996
 
     Net interest income for the year ended December 31, 1996, was $9,561,000,
an increase of $577,000 or 6.4% compared to net interest income of $8,984,000 in
1995, which was $629,000 or 7.52% higher than the $8,355,000 reported in 1994.
The overall tax-equivalent earning asset yield was 9.52% in 1996 compared to
 
                                       21
<PAGE>   23
 
9.68% in 1995, and 8.37% in 1994. These results were primarily due to flat
market interest rates in 1996 and a modest upturn in interest rates in 1994.
Further, the decline in yield from 1995 to 1996 was caused by growth in the
proportion of relatively lower-yielding investments to earning assets. Loans,
which generally carry a higher yield than investment securities and other
earning assets, comprised 66.0% of average earning assets during 1996, compared
to 72.7% in 1995 and 64.5% in 1994. During the same periods, average yields on
loans decreased from 10.72% in 1995 to 10.67% in 1996, compared to 10.00% in
1994. Investment securities comprised 28.8% of average earning assets in 1996
which was up from 24.5% in 1995, after a decrease from 28.0% in 1994. The
increased portfolio of investment securities in 1996 compared to 1995 reflects
improved yields on investments funded by an increase in deposit liabilities
during a period when loan demand had stabilized. The decrease in the portfolio
of investment securities from 1994 to 1995 reflects the declining yields
realized from these investments during 1994 to 1995 and the greater yield
opportunity recognized in growing VRB's loan portfolio. Tax-equivalent interest
yields on investment securities have ranged from 7.66% in 1996 to 7.05% in 1995
and 5.71% in 1994.
 
     Interest cost as a percentage of earning assets increased to 2.52% in 1996
compared to 2.35% in 1995 and 1.69% in 1994. Local competitive pricing
conditions and funding needs for VRB's investments in loans were the primary
determinants of rates paid for deposits during 1994, 1995 and 1996.
 
PROVISION FOR LOAN LOSSES
 
  For the Six Months Ended June 30, 1996 and 1997
 
     VRB's loan loss reserve was $1,391,000 and $1,602,000 for the periods ended
June 30, 1996 and 1997. This equates to 1.46% of total loans for both periods as
management adjusts the reserve to keep pace with the growth in VRB's overall
loan portfolio. Losses on loans charged to the reserve during the first six
months of 1996 and 1997 amounted to $22,000 and $49,000. Such charge-offs have
been partially offset by loan recoveries of $6,000 and $19,000 for the same
periods.
 
  For the Years Ended December 31, 1994, 1995 and 1996
 
     The loan loss provision increased between 1995 and 1996 as a result of the
increased loan volume and management's desire to maintain the reserve at an
adequate level relative to total loans. Management believes the loan loss
provision maintains the reserve for loan losses at an appropriate level. The
reserve for loan losses was $1,632,000 at December 31, 1996, as compared to
$1,407,000 at December 31, 1995 and $1,414,000 at December 31, 1994. VRB's ratio
of reserve for loan losses to total loans was 1.61% at December 31, 1996,
compared to 1.56% at December 31, 1995 and 1.57% at December 31, 1994.
 
     Recoveries have been nearly equivalent to or have exceeded charge-offs over
the past three-year period. Net chargeoffs for 1996 were approximately $25,000
which compares to net charge-offs of approximately $7,000 in 1995 and $39,000 in
1994. Loans on nonaccrual status have been insignificant. At December 31, 1996,
nonaccrual loans totaled $58,000 compared to $52,000 at December 31, 1995 and
$7,000 at the end of 1994. Management believes this loan loss experience is a
result of the stringent underwriting and collection practices employed by VRB,
the strength in the local economy and the quality of the loan portfolio. When a
charge to the loan loss provision is recorded, the amount is based on past
charge-off experience, a careful analysis of the current portfolio, and
evaluation of future economic trends in VRB's market area. Management continues
to closely monitor the loan quality of new and existing relationships. Net loan
losses or recoveries in 1997 are expected to approximate VRB's recent historical
experience.
 
NON-INTEREST INCOME
 
  For the Six Months Ended June 30, 1996 and 1997
 
     Non-interest income, primarily consisting of services charges and related
fees, increased $31,000 or 4.5% from the period ended June 30, 1996 to June 30,
1997. The increase was the result of increasing deposit volumes and related
service fees. Service charges were $489,000 in 1996 and compared to $522,000 in
1997. Although VRB did not recognize any gains on security transactions as of
June 1996, it did realize a gain of $7,000 on the sale of investment securities
for the six months ended June 1997.
 
                                       22
<PAGE>   24
 
  For the Years Ended December 31, 1994, 1995 and 1996.
 
     Total non-interest income has declined from 1994 through year-end 1996.
Over the three year period non-interest income has ranged from $1,512,000 in
1994 and $1,380,000 in 1995 to $1,371,000 in 1996. While service charges on
deposit accounts have remained stable from 1994 through 1996, other operating
income, which includes earnings from VRB's real estate mortgage processing
activities, declined after 1994. Closure of VRB's manufactured housing lending
division early in 1995 significantly affected other operating income levels such
that revenues of approximately $480,000 in 1994 declined to nearly $370,000 in
1995 and approximately $392,000 in 1996. VRB does not actively trade or sell
investment securities and, consequently, has received no material income from
such transactions during the period from 1994 to 1996.
 
NON-INTEREST EXPENSE
 
  For the Six Months Ended June 30, 1996 and 1997
 
     Other operating expenses consist principally of employees' salaries and
benefits, occupancy costs, data processing and communication expenses, FDIC
insurance premiums, professional fees, and other noninterest expenses. A measure
of VRB's ability to contain noninterest expenses is the efficiency ratio. This
statistic is derived by dividing total noninterest expenses by total interest
and noninterest income. As of June 30, 1997, the ratio had remained steady at
41.6% compared to 41.1% for the corresponding period of 1996. The efficiency
ratio reflects management's emphasis and success in closely monitoring and
controlling noninterest expenses.
 
     Non-interest expense increased $401,000 or 13.9% from $2,879,000 for the
six months ended June 30, 1996 to $3,280,000 in the corresponding period in
1997, primarily due to an increase in staffing costs, as well as increases in
other key operating costs such as occupancy expense and supplies.
 
  For the Years Ended December 31, 1994, 1995 and 1996.
 
     Non-interest expense decreased $233,000 or 3.8% form $6,062,000 for the
year ended December 31, 1995 to $5,829,000 for the year ended December 31, 1996.
The decline was attributed to a drop in deposit insurance premiums of $141,000
and salary expense of $148,000 partially offset by increase, in occupancy,
communications and data processing expenses.
 
     Salary and benefit expense of $3,693,000 in 1996 represented a decrease of
$148,000 from the $3,841,000 reported in 1995 which was $205,000 or 5.6% higher
than the $3,636,000 reported in 1994. As of December 31, 1996, VRB had 116
fulltime equivalent employees which compares to 107 and 111 as of December 31,
1995 and 1994, respectively.
 
     Net occupancy expenses consist of depreciation on premises and equipment,
maintenance and repair expenses, utilities and related expenses. The Company's
net occupancy expense in 1996 of $630,000 was $22,000 or 3.6% higher than the
$608,000 reported in 1995, which was $78,000 or 11.4% less than the $686,000
reported in 1994. At the close of 1995, VRB embarked upon a three year plan to
upgrade its data processing systems. The result will increase operating
efficiencies, but may also cause increases to net occupancy expenses during
future years.
 
     Advertising and communications expenses have increased consistently from
1994 through 1996 as VRB continues to promote and advertise its products and
services to the communities it serves. In 1996, communication expenses of
$226,000 were 10.8% higher than 1995 which were 7.3% greater than 1994.
Expenditures relating to communications are important for VRB to realize its
market share and growth goals for the future.
 
     FDIC insurance premiums are a function of outstanding deposit liabilities
and through 1994 increased consistent with VRB's growth in depository
relationships. However, insurance expense decreased nearly $139,000 in 1995 when
VRB received a premium refund from the FDIC after the Bank Insurance Fund was
recapitalized. Because the Bank Insurance Fund is adequately capitalized, the
Company was required to make
 
                                       23
<PAGE>   25
 
only nominal premium payments in 1996. For the three years ended December 31,
1996, the Company has been rated to pay the lowest premiums available for its
deposit insurance coverage.
 
     All other noninterest expenses, as a percentage of total revenues, declined
in 1996 compared to both 1995 and 1994. In 1996, all other noninterest expenses
were 8.8% of total revenues while in 1995 and 1994 these items were 9.5% and
10.2%, respectively, of total revenues. Cost controls and careful management of
expenses have contributed to reduction in other noninterest expenses.
 
INCOME TAXES
 
     The provision to income taxes for the six month period ending June 30, 1997
was $916,000 representing an effective tax rate of 34%, compared to 772,000 or
33% for the six month period ended June 30, 1996.
 
     The provision for income taxes amounted to $1,602,000, $1,395,000, and
$1,335,000 for 1996, 1995, and 1994, respectively. The provision resulted in
effective combined federal and state tax rates of 33% in 1996 and 32% and 35% in
1995 and 1994, respectively. Effective tax rates differ from combined estimated
statutory rates of 38% principally due to the effects of nontaxable interest
income which is recognized for book but not for tax purposes. In addition,
during 1995, the Company's state income tax rate was reduced 50% from 6.6% to
3.3% as a result of surplus revenues received by the State of Oregon.
 
LOAN LOSSES AND RECOVERIES
 
     Although management recorded a $250,000 provision for loan losses in 1996
to support loan portfolio growth, the quality of the loan portfolio remains
strong. At June 30, 1997, the allowance for loan losses of $1,602,000 was
considered sufficient to absorb possible losses on loans which may become
uncollectible based on evaluations by Management.
 
     The amount of the allowance for loan losses is assessed by management on a
regular basis to ensure that it is sufficient to cover potential future loan
losses. Management does not specifically allocate the reserve for loan losses by
loan category. The reserve balance and amount of provision charged to operations
is based primarily on management's evaluation of the entire portfolio. This
analysis includes review of the following factors: (a) the volume and mix of the
existing loan portfolio, including the volume and severity of nonperforming
loans and adversely classified credits, as well as analysis of net charge-offs
experienced on previously classified loans; (b) the extent to which loan
renewals and extensions are used to maintain loans on a current basis and the
degree of risk associated with such loans; (c) the trend in loan growth,
including any rapid increase in loan volume within a relatively short period of
time; (d) general and local economic conditions affecting the collectibility of
VRB's loans; (e) the relationship and trend over the past several years of
recoveries as a percentage of previous years' charge-offs; and, (g) available
outside information of a comparable nature regarding the loan portfolios of
other banks, including peer group banks. The following table shows VRB's loan
loss performance for the periods indicated:

</TABLE>
 
     As the table illustrates, during 1995 and 1996 and for the six months ended
June 30, 1997, charge-offs exceeded recoveries by a nominal amount. At June 30,
1997, VRB had nonperforming assets of $49,000 compared to $70,000 at December
31, 1996. The majority of these assets are comprised of commercial and
consumer-based transactions. Management believes it is reasonable to expect a
significant portion of such amounts may be charged against the reserve in the
future.

  Investments
 
     At June 30, 1997, VRB's portfolio of investment securities totaled
$39,809,000, a $476,000 or 1.18% decrease when compared to a December 31, 1996
securities portfolio of $40,285,000 and $1,161,000, respectively. Investments in
federal funds sold (an overnight investment) and Federal Home Loan Bank stock
were $12,400,000 at June 30, 1997. The balance of federal funds sold is
influenced by cash demands, customer deposit levels, loan activity, and other
investment transactions.
 
     Investment securities held at December 31, 1996, totaled $40,285,000,
representing a $3,204,000 or 8.6% increase when compared to December 31, 1995
investment securities totals of $37,081,000. Total investment
 
                                       25
<PAGE>   27
 
securities at December 31, 1994 were 8.57% higher than those reported in 1995.
Increases or decreases in the investment portfolio are primarily a function of
loan demand and changes in VRB's deposit structure.
 
     VRB follows a financial accounting principle which requires the
identification of investment securities as held-to-maturity or
available-for-sale. Securities designated as held-to-maturity are those that VRB
has the intent and ability to hold until they mature or are called rather than
those that management may sell if liquidity requirements dictate or alternative
investment opportunities arise. The mix of available-for-sale and
held-to-maturity investment securities is considered in the context of VRB's
overall asset-liability policy and illustrates management's assessment of the
relative liquidity of VRB. At June 30, 1997, the investment portfolio consisted
of 54.0% available-for-sale securities and 46.0% held-to-maturity investments,
comparable to December 31, 1996, and 57.3% available-for-sale securities and
42.7% held-to-maturity investments at December 31, 1995. This mix provides VRB
greater investment flexibility than it had in 1994 when the portfolio was 15.8%
available-for-sale securities and 84.2% in held-to-maturity securities at
December 31, 1994.
 
     At June 30, 1997, VRB's investment portfolio had total net unrealized gains
of approximately $164,000. This compares to net unrealized gains of
approximately $269,000 at December 31, 1996, $280,000 at December 31, 1995, and
unrealized losses of $1,201,000 at December 31, 1994. Unrealized gains and
losses reflect changes in market conditions and do not represent the amount of
actual profits or losses VRB may ultimately realize. Actual realized gains and
losses occur at the time investment securities are sold or redeemed.
 
     Federal funds sold are short term investments which often mature on a daily
basis. VRB invests in these instruments to provide for additional earnings on
excess available cash balances. Because of their short maturities, the balance
of federal funds sold fluctuates dramatically on a day-to-day basis. The balance
on any one day is influenced by cash demands, customer deposit levels, loan
activity and other investment transactions. Investments in federal funds sold
totaled $12,400,000 at June 30, 1997, compared to $11,300,000 at December 31,
1996, and to $4,500,000 and $6,800,000 at December 31, 1995 and 1994,
respectively.
 
     In 1994, VRB became a member and stockholder in the Federal Home Loan Bank
of Seattle. At December 31, 1996, the Bank held $1,120,000 in Federal Home Loan
Bank stock. VRB's relationship and stock investment with the Federal Home Loan
Bank provides, in addition to dividend earnings, a borrowing source for meeting
liquidity requirements.

  Loans
 
     Outstanding loans totaled $107,929,000 at June 30, 1997, representing an
increase of $8,153,000 or 8.2% compared to $99,776,000 at December 31, 1996.
Loan commitments (principally real estate construction notes) grew to $21.8
million at June 30, 1997, representing the highest level of undisbursed loan
funds for the year. Loan commitments amounted to $9.5 million at June 30, 1996
and $16.0 million at December 31, 1996.
 
     Reflective of VRB's customer base, as well as trends within the local
economy, 77.2% of VRB's net loan portfolio consists of loans secured by real
estate. This percentage is consistent with previous reporting periods such as
December 31, 1996 and June 30, 1996 when 75.5% and 74.5% of all loans were
within this category. Loans secured by real estate include loans made for
purposes other than financing purchases of real property, such as inventory
financing and equipment purchases, where the collateral provided to VRB is in
the form of real property.

  Deposits
 
     From December 31, 1996 to June 30, 1997 deposit growth has slowed,
increasing by $879,000 or 0.6%. This slower growth was caused primarily by
management's decision to discontinue its competitive rates on deposits at a time
when VRB had no need for additional liquidity. Non-interest bearing deposits
continue to be a reliable and substantial portion of VRB's deposit base
accounting for 29.7% of total deposits at June 30, 1997.
 
     From December 31, 1995 to December 31, 1996, total deposits increased by
$22,825,000, or 17.2% from $132,744,000 to $155,569,000. This represents an
increase from 1995, when total deposits increased by 5.8% over 1994. Deposit
growth in 1996 was due to management's decision to promote an attractive pricing
strategy, increased marketing, and increased emphasis on implementing a sales
culture within the branches. The growth in deposit accounts has primarily been
in money market checking accounts and non-interest-bearing checking accounts.
Nonvolatile, non-interest-bearing demand deposits, also referred to as core
deposits, continued to represent a significant percentage of VRB's deposit base.
To the extent that VRB is able to fund operations with non-interest-bearing core
deposits, net interest spread, the difference between interest income and
interest expense, will improve. At December 31, 1996, these non-interest-bearing
demand deposits accounted for 26.8% of total deposits which was down slightly
from 28.7% as of December 31, 1995. Nevertheless, average outstanding core
deposit balances improved in 1996 over 1995 by approximately $3,500,000 to
$39,836,000.
 
     Interest bearing deposits consist of NOW, money market, savings and time
certificate accounts. By their nature, interest bearing account balances will
tend to grow or decline as VRB reacts to changes in competitors' pricing and
interest payment strategies. In 1996, total interest bearing deposit accounts of
$113,823,000 increased $19,176,000 or 20.3% from 1995. Significant growth in
interest-bearing demand deposits ($15,774,000 or 29.6% for the year ended
December 31, 1996) and time deposits ($5,462,000 or 22.9%) was more than
sufficient to offset a decline in savings deposits ($2,060,000 or 11.8%).
Management's analysis of the shifts in interest bearing deposit mix indicates
that a significant number of VRB's savings account customers shifted into higher
earning time deposit accounts during the year.
 
     In 1994 and early 1995, management purposely held down interest paid on
time deposits as it was unwilling to aggressively compete for such deposits when
no need for additional liquidity existed. This allowed VRB to improve its net
interest margin by keeping down the interest paid on deposit accounts. As a
result, however, increased competition from local financial institutions and
other investment sources attracted depositors away from VRB. As competition
eased for time deposit accounts and interest rates paid for such accounts became
more favorable in 1995 and 1996, VRB became more aggressive in pricing its time
deposit products. This resulted in the deposit growth in 1995 and 1996.
 
     VRB, by policy, does not depend on brokered deposits nor high priced time
deposits. At June 30, 1997, time certificates of deposits in excess of $100,000
totaled $5,581,000 or 21.4% of total outstanding time deposits, compared to
$7,051,000 or 24.1% of total outstanding time deposits at December 31, 1996, and
12.1% and 13.0% as of December 31, 1995 and 1994, respectively.

  Asset-Liability Management/Interest Rate Sensitivity
 
     The principal purpose of asset-liability management is to manage VRB's
sources and uses of funds to maximize net interest income under different
interest rate conditions with minimal risk. A part of asset-liability management
involves interest rate sensitivity, the difference between repricing assets and
repricing liabilities in a specific time period. This analysis provides an
indication of VRB's earnings risk due to future interest rate changes. At June
30, 1997, the analysis indicated that the earnings risk was within VRB's policy
guidelines.
 
     A key component of the asset-liability management is the measurement of
interest-rate sensitivity. Interest-rate sensitivity refers to the volatility in
earnings resulting from fluctuations in interest rates, variability in spread
relationships, and the mismatch of repricing intervals between assets and
liabilities. Interest-rate sensitivity management attempts to maximize earnings
growth by minimizing the effects of changing market rates, asset and liability
mix, and prepayment trends.
 
     Management reviews VRB's interest-rate sensitivity position on an ongoing
basis, and prepares strategies to adjust that sensitivity, as appropriate.
Consideration is given and strategies are developed to minimize the effect of
any compression on net interest income which may arise from earlier repricing of
loans at lower rates or earlier repricing of deposits at higher rates. As of
June 30, 1997, management believes its strategies are sufficient to offset any
compression on net interest income that may arise from asset and liability
repricing in the near term.
 
     The table below presents interest-rate sensitivity data as of June 30,
1997. The interest rate gaps reported in the 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 view in subsequent periods. Active management
dictates that longer-term economic views are balanced against the prospects of
short-term interest rate changes in all repricing intervals.

     The table illustrates that VRB is liability-sensitive for the 12 month
period following June 30, 1997, and asset-sensitive thereafter. In an
environment of increasing interest rates, the theoretical operating results of
VRB would be adversely affected for the 12 months following June 30, 1997, and
favorably affected thereafter. Conversely, in a declining interest-rate
environment, VRB's theoretical operating results would be favorably affected for
the 12 month period following June 30, 1997, and adversely thereafter.
 
  Shareholders' Equity
 
     Shareholders' equity increased $1,692,000 during the first half of 1997.
Shareholders' equity at June 30, 1997 amounted to $21,880,000 compared to
$20,188,000 at December 31, 1996. The increase in equity reflects consolidated
earnings of $1,777,000 and the proceeds from the exercise of stock options
(8,383 shares for a total of $36,000). These additions to equity were partially
offset by a change in the value of the "available for sale" portion of the
investment portfolio. The unrealized gain/loss on this portion of the portfolio
is reflected in shareholders' equity. The current value of this segment of VRB's
investment portfolio declined $121,000 when comparing December 31, 1996 to June
30, 1997.
 
  Return on Equity and Assets
 
     Net income for the six months ended June 30, 1997, totaled $1,777,000 for
an annualized return on average shareholders' equity 17.03% and an annualized
return on average outstanding assets of 2.01%. These returns compare to a 17.35%
return on average equity and 2.01% return on average assets for the same period
in 1996.

LIQUIDITY
 
     Liquidity represents the ability to meet cash flow requirements and
financial commitments at a reasonable cost, while retaining the flexibility to
take advantage of business opportunities. Management has always placed a high
priority on maintaining a high liquidity through a moderate loan-to-deposit
ratio and a conservative investment portfolio. As of June 30, 1997, VRB's
loan-to-deposit ratio was a moderate 69.0%. Additionally, although no balances
were outstanding at June 30, 1997, VRB has borrowing agreements with Federal
Home Loan Bank of Seattle for cash advances of $8.5 million and long-term
borrowings of $9.1 million, as well as approximately $12.4 million in federal
funds sold to meet potential liquidity needs. As of June 30, 1997, approximately
$9,883,000 or 24.8% of the securities portfolio matures within one year.
Management believes these factors are indicative of the emphasis placed upon
maintaining sufficient liquidity for VRB.
 
     VRB has entered into agreements to acquire Colonial Banking Company
("Colonial") which are expected to have a modest effect on VRB's liquidity. The
net proceeds of the Offering will be used to fund a significant portion of the
purchase price of approximately $15.7 million. See "Use of Proceeds." In
addition, Colonial has historically had a higher cost of funds than VRB,
resulting from a higher proportion of deposits held in interest-bearing accounts
and higher rates paid on certain of those interest-bearing liabilities compared
to VRB, which has a significant portion of its deposit liabilities in
non-interest-bearing accounts. VRB management anticipates that as the interest
rates paid on Colonial deposits are reduced, some depositors will withdraw their
funds, decreasing VRB's liquidity. VRB management believes that VRB has ample
cash and cash-equivalent resources to fund the Colonial purchase and any
anticipated deposit run-off without restricting its growth or materially
compromising its liquidity.
 
CAPITAL
 
     In 1989, banking regulators adopted risk-based capital guidelines under
which one of four risk weights is applied to balance sheet assets, each with
different capital requirements based on the credit risk of the asset. VRB is
required to maintain minimum amounts of capital to "risk weighted" assets, as
defined by banking regulators. At June 30, 1997, VRB was required to have Tier 1
and Total Capital ratios of 4.0% and 8.0%, respectively. VRB's actual ratios at
that date were 16.2% and 17.5%, respectively.
 
     Management seeks to attain a level of capital consistent with appropriate
business risk and an ongoing need for financial flexibility. Adequacy of capital
depends on the assessment of a number of factors such as stability of earnings,
asset quality, liquidity, and economic conditions. The primary capital-to-asset
leverage
 
                                       31
<PAGE>   33
 
ratio was 11.9% at June 30, 1997. With a strong equity-to-assets ratio, VRB
enjoys greater financial flexibility and less dependence upon its deposit base
to support loan and investment activities.
 
     The proposed cash acquisition of Colonial will significantly reduce the
capital ratios for VRB, particularly its Tier 1 capital ratio, as goodwill
incurred as a result of the acquisition is deducted from VRB's capital. For
example, the pro forma Tier 1 capital ratio for June 30, 1997, would drop from
16.2% to 11.9% excluding the effects of the proposed stock offering. Although
VRB would exceed all capital requirements, raising additional capital is deemed
prudent by management and would ensure that VRB will continue to qualify as
"well-capitalized" under regulatory guidelines.

INTRODUCTION
 
     VRB is the largest community bank in southern Oregon, currently operating
nine full-service branches in the Rogue Valley. As of June 30, 1997, VRB had
assets of $179.6 million and deposits of $156.4 million. VRB has entered into an
agreement to acquire Colonial Banking Company ("Colonial") which will add four
branches and $100.6 million in deposits, increasing VRB's market share to over
15% of commercial bank deposits in the Rogue Valley. See "Colonial Banking
Company Acquisition."
 
     VRB has delivered 29 consecutive years of profitability. During the most
recent five years, it has increased earnings by an average of 18% per year and
in each year has achieved a return on average equity greater than 16%. During
the same period, VRB's return on average assets has increased from 1.61% for
1992 to 1.99% for 1966. VRB has sustained a strong asset quality and
consistently performed in the top quartile when comparing its return on average
equity to its national peer group comprising over 900 banks with assets of
between $100 and $300 million and multiple branches located in metropolitan
areas.
 
     The consolidation of the banking industry in Oregon has had a positive
effect on VRB. Major regional banks have chosen to focus on larger metropolitan
markets and to de-emphasize personal service to achieve efficiencies. VRB
continues to introduce new products while maintaining the personal service and
local decision-making believed to be important to its customers. Its high level
of demand deposit accounts (29.7% of total deposits at June 30, 1997) has
significantly contributed to its consistently low cost of funds and high net
interest margin. VRB's growing base of core deposits confirms its belief that
its product delivery approach is attractive to a significant number of customers
in its market.
 
     VRB offers a broad range of commercial banking services, primarily to small
and medium-sized businesses, professionals, farmers and retail customers,
including commercial, real estate and agricultural loans, accounts receivable
and inventory financing, consumer installment loans, acceptance of deposits, and
personal savings and checking accounts. A majority of the VRB's loans are
commercial loans collateralized with real estate.
 
INDUSTRY OVERVIEW
 
     The commercial banking is continuing to undergo increased competition,
consolidation and change. Non-insured financial service companies such as mutual
funds, brokerage firms, insurance companies, mortgage companies and leasing
companies are offering alternative investment opportunities for customers' funds
as well as additional lending sources for their needs. Banks have been granted
extended powers to better compete including the limited right to sell insurance
and securities products. Despite the expanded products and services available to
banks, the percentage of financial transactions handled by commercial banks has
dropped steadily. Although the dollar amount of bank deposits has remained
steady, such deposits represent less than 20% of household financial assets
compared to over 35%, 25 years ago. This trend represents a continuing shift to
investments in stocks, bonds, mutual funds and retirement accounts. However, in
recent years, relatively stable interest rates and a growing economy have
permitted all segments of banking industry to improve net interest margins and
returns on assets, resulting in stronger balance sheets and earnings.
 
     To improve competitiveness, commercial banks are reducing costs through
operating efficiencies gained by consolidation and implementing alternative ways
of providing bank products. Although new community banks continue to be
organized, bank mergers substantially outnumber new bank formations. In the last
dozen years, the number of commercial banks has dropped from 14,000 to 9,500.
Management expects this trend to continue.
 
     To more effectively and efficiently deliver its products, banks are opening
branches located inside retail stores, installing more ATMs, and investing in
technology to enable telephone, personal computer and interest banking. While
all banks are experiencing the effects of the changing environment, the manner
in which banks choose to compete is increasing the gap between larger
super-regional banks and community banks. The super-regional banks are committed
to becoming regional "brands" providing a broad selection of products at
 
                                       33
<PAGE>   35
 
low cost and with advanced technology while community banks provide most of the
same products but with a higher commitment to personal service and with local
ties to the communities they serve.
 
BUSINESS STRATEGY
 
     VRB seeks significant growth in its earnings assets while maintaining a
high return on equity. VRB believes that this objective can be achieved by
continuing to emphasize personalized, quality banking products and services to
small and medium-sized businesses, professionals and retail customers. VRB
intends to increase its market penetration in its existing markets and to expand
into new markets through acquisitions. VRB's strategy consists of the following:
 
     - Provide a full range of banking products and personalized service.  VRB
       believes offering products with a high level of personal service attracts
       and retains customers. Although many of its customers desire personal
       banking services, VRB also has made a commitment to provide new
       technological services to attract a broader customer base. These products
       and services include 24-hour telephone account access, a recently
       developed debit card program and an expanded ATM network.
 
     - Increase market share in existing markets.  VRB believes there is
       significant potential to increase its business with current customers and
       attract new customers in its existing market. Early in 1995, VRB embarked
       on a sales training program and in 1996 appointed a Corporate Sales
       Officer with the responsibility for improving the business development
       skills of employees. VRB also believes it can gain more customers within
       the Rogue Valley by continuing to distinguish itself from larger banks,
       all of which are headquartered in other states and have reduced personal
       service and transferred lending decisions away from local branches. As of
       June 30, 1997, VRB's market share of commercial bank deposits in the
       Rogue Valley amounted to 9.3%, up from 7.7% on December 31, 1995. VRB
       believes this increase of over 20% in an eighteen month period is a
       direct result of its increased marketing efforts and validates VRB's
       belief that personalized service is important to a significant segment of
       the market. The addition of Colonial's deposits is expected to increase
       VRB's total market share to 15% of commercial bank deposits in the Rogue
       Valley.
 
     - Explore opportunistic acquisitions.  After the integration of Colonial,
       VRB intends to pursue acquisitions of other community banks. Although VRB
       is not currently engaged in any acquisition discussions, it believes that
       it will be able to supplement internal growth with complementary
       acquisitions.
 
PRODUCTS AND SERVICES
 
     VRB created a broad portfolio of products and services tailored to meet the
banking requirements of targeted customers in its market area. These include:
 
     Deposit Products.  VRB has an array of deposit products for customers,
including non-interest checking accounts, interest-bearing checking and savings
accounts, money market accounts and certificates of deposit. These accounts
generally 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. VRB does not pay brokerage commissions to attract
deposits. It strives to establish customer relations to attract core deposits in
non-interest-bearing transactional accounts and, thus, to reduce its cost of
funds.
 
     Commercial Loans.  VRB offers specialized loans for its business and
commercial customers, including equipment and inventory financing, real estate
construction loans, SBA loans for qualified businesses and accounts receivables
financing. Commercial lending is the primary focus of VRB's lending activities,
and a significant portion of the its loan portfolio consists of commercial
loans. For regulatory reporting purposes, a substantial portion of VRB's
commercial loans are designated as real estate loans, as the loans are secured
by mortgages and trust deeds on real property, although the loans may be made
for purposes of financing commercial activities, such as accounts receivables,
equipment purchases and inventory or other working capital needs.

     Real Estate Loans.  Real estate loans are available for construction,
purchasing and refinancing residential owner-occupied and rental properties.
Borrowers can choose from a variety of fixed and adjustable rate options and
terms. Real estate loans reflected in the loan portfolio are in large part loans
made to commercial customers that are secured by real property. VRB provides
customers access to long-term conventional real estate loans through its
mortgage loan department which processes applications for a variety of real
estate lenders.
 
     Consumer Loans.  VRB provides loans to individual borrowers for a variety
of purposes, including secured and unsecured personal loans, home equity and
personal lines of credit, motor vehicle loans, and student loans.

portfolio at September 30, 1997, classified by distribution among types of

     Other Banking Services.  In support of its focus on personalized service,
VRB offers additional products and services for the convenience of its
customers. These include a recently introduced debit card program, automated
teller machines located at each of VRB's offices, and a telephone banking
service that allows customers to speak directly with a customer service

VRB does not currently charge for these services.
 
MARKET AREA
 
     VRB primarily accepts deposits and makes loans in Jackson and Josephine
Counties (the Rogue Valley) in Oregon. As a community bank, VRB has certain
competitive advantages because of its local focus, but VRB is also more closely
tied to the local economy than competitors who serve a number of geographic
markets.
 
     VRB's market area has become increasingly popular as a family community and
retirement area, and has seen an increase in the population of approximately
14.5% during the period from 1990 to 1996. The Rogue Valley had a 1996
population of approximately 240,000. About half of the population of each county
is in an urbanized area: Medford and Ashland in Jackson County and Grants Pass
in Josephine County.
 
     Over the past 10 years, the employment base of the Rogue Valley has
undergone significant change. In an area that has previously been dependent upon
timber manufacturing, employment within this sector has dropped from 30% of
total wages in the early 1970s to just under 12% in 1995. The region's largest
employers
 
                                       35
<PAGE>   37
 
have diversified and include in addition to timber and non-timber manufacturers,
municipalities, higher education, and medical industries. Further, commercial
development and retail growth has created approximately 3,000 jobs since 1992 as
the service sector responds to the influx of new residents into the region.
Although much improved from the high unemployed levels experienced during the
recession years of 1985 through 1992, unemployment remains above Oregon and U.S.
averages in both counties. Tourism has become increasingly important.
Agriculture, although a small industry in terms of employment, remains a
significant economic factor. This diverse industry base is strengthening the
Rogue Valley economy creating new growth opportunities.
 
     The region's non-farm employment is anticipated to grow in excess of 20%
over the next 10 years, adding almost 20,000 jobs. The largest growth (estimated
at over 40%) is expected in services sector and employment. Wages, in real
terms, have declined approximately 5% as retail and service jobs supplant
manufacturing employment. As of September 1997, average weekly wages were 83.9%
and 76.5% for Jackson and Josephine County, respectively, of the state average.
 
     A significant change in the makeup of the population in the two counties
has occurred with the emigration of working families and the influx of retirees.
With these population shifts, a high percentage of personal income is now
derived from sources other than wages and salaries, particularly in Josephine
County where 51% of personal income is from non-wage or salary sources, compared
to 40% in Jackson County and approximately 35% statewide. Transfer payments
account for approximately 20% of personal income in Jackson County, and
approximately 28% in Josephine. Management believes that the segments of the
population experiencing the highest growth are those who are more likely to
desire the personal services and convenience offered by the Company.
 
MARKETING
 
     VRB's ability to increase its share of the financial service market in the
Rogue Valley is driven by a marketing plan consisting of several key components.
A principal objective is to create and foster a sales culture in each office.
Employees are trained to cross-sell, offering appropriate products and services
to existing customers and attempting to increase the business relationships VRB
shares with its existing customers. VRB regularly examines the desirability and
profitability of adding new products and services to those currently offered.
VRB promotes specific products by media advertising but relies primarily on
direct contacts for new business. VRB recognizes the importance of community
service and supports employee involvement in community activities. This
participation allows VRB to make a contribution to the communities it serves as
well as to increase VRB's visibility in its market area and thereby increase
business opportunities.
 
MANAGEMENT INFORMATION SYSTEMS
 
     VRB recently created a Director of Information Technology position to
oversee all areas of technology within VRB, such as data processing and
electronic banking. VRB recently hired an experienced individual with extensive
technology and operations experience in financial institutions to fill this role
on November 1, 1997.
 
     VRB maintains an "in house" system for processing all core banking
applications. The system utilizes Information Technology Systems, Inc. ("ITI")
software and Unisys hardware. VRB converted to "in house" processing in 1991 to
gain control over quality and the cost of such services. In addition, VRB
utilizes ITI software for investment securities accounting, 24-hour telephone
banking and maintaining shareholder records.
 
     VRB maintains a Disaster Recovery Plan for its data center operations and
network of branches and subscribes to a service which will provide on site
processing within 48 hours of the company sustaining a disaster. VRB maintains
insurance to fund the expense of the service. Management has acknowledged and is
evaluating the well-publicized potential problem relating to the impact on
computer systems of the date change on January 1, 2000, known as the "Year 2000"
issue. Management expects no difficulties or extraordinary expense in
successfully addressing the issue.

COMPETITION
 
     The geographic market area served by VRB is highly competitive with respect
to both deposits and loans. VRB competes principally with commercial banks,
savings and loan associations, credit unions, mortgage companies, and other
financial institutions. The major commercial bank competitors are super-regional
institutions headquartered outside the State of Oregon, and their deposits
represent approximately 79% of statewide commercial bank deposits as of June 30,
1997. Within the Rogue Valley, these institutions hold approximately 75% of the
deposits. The major banks have the advantage of offering their customers
services and statewide banking facilities that VRB does not offer.
 
     VRB's primary competition for deposits comes from commercial banks, savings
and loan association, credit unions, and money market funds, some of which may
offer higher rates than VRB can or is willing to offer. Secondary competition
for funds comes from issuers of corporate and government securities, insurance
companies, mutual funds, and other financial intermediaries. Other than with
respect to large certificates of deposit, VRB competes for deposits by offering
a variety of deposit accounts at rates generally competitive with similar
financial institutions in the area.
 
     VRB's competition for loans comes principally from commercial banks,
savings and loan associations, mortgage companies, finance companies, insurance
companies, and other institutional lenders. Many of its competitors have
substantially higher single borrower lending limits than those of VRB. VRB
competes for loan origination through the level of interest rates and loan fees
charged, the variety of commercial and mortgage loan products, and the
efficiency and quality of services provided to borrowers. Lending activity can
also be affected by the availability of lendable funds, local and national
economic conditions, current interest rate levels, and loan demand. As described
above, VRB competes with the larger commercial banks by emphasizing a community
bank orientation and efficient personal service to local customers, particularly
local lending. See "Business -- Business Strategy."
 
PROPERTIES
 
     VRB's main office is located in Rogue River, Oregon, and conducts its
business through nine full service branches throughout the Rogue Valley. All of
the branches have drive-up facilities and automated teller machines.
Additionally, VRB maintains a satellite automated teller machine in Medford,
Oregon. All but two premises are owned by VRB and VRB has options to extend
existing leases on the leased facilities. VRB's nine offices range in size from
approximately 1,100 square feet to slightly more than 8,000 square feet. In
three branches, excess space is leased to others. The following sets forth
certain information regarding VRB's branches as of June 30, 1997.

EXECUTIVE COMPENSATION PLANS
 
  Incentive Based Bonus Plan
 
     VRB's Incentive Based Bonus Plan for executive officers provides for
establishment of a pool of funds equal to 11.25% of net profits in excess of a
one percent return on average assets. The pool is limited to no more than
seventy-five percent of the executive officers annual base salary. The pool is
then divided between the three highest paid executive officers on a pro-rata
basis, based on base salary compensation paid during the preceding year. The
executive must be employed at the time the pool is distributed in order to
participate. Distribution normally occurs during the first quarter of each year.
The Board reserves the right to modify or terminate the plan at its discretion.
 
     For the year ending December 31, 1996, profits generated by VRB amounted to
$3,251,000. These earnings equaled a return on average assets of 1.99% and a
return on average shareholder equity of 17.26%. Based on the performance of VRB
and the Incentive Based Bonus Plan in place for 1996, a bonus pool of $195,000
was established for payment of bonuses to executive officers. Pursuant to the
Plan, the Board awarded incentive bonus payments of $67,500 to each of Messrs.
Haden and Anderson during February 1997.
 
  Employment and Change of Control Agreements
 
     VRB has entered into special agreements with certain executive officers.
These agreements are intended to help ensure that the executives remain in the
employ of VRB.
 
     WILLIAM HADEN
 
     VRB entered into an agreement with President and Chief Executive Officer,
William Haden, to provide at VRB's expense a term life insurance policy on Mr.
Haden's life in the amount of $350,000, through the year 2002 and at $150,000
thereafter. The ownership and right to name the beneficiary under the policy is
reserved to Mr. Haden. The cost of providing this policy is estimated to be less
than $1,000 during 1996. The policy was not in place during 1995.
 
     The agreement with Mr. Haden additionally provides for a "change in
control" payment equal to his base salary plus any cash bonuses or other
compensation paid to or for his benefit, during the fiscal year preceding
 
                                       41
<PAGE>   43
 
the change in control. Further, if Mr. Haden leaves VRB following a change in
control, VRB will, at its expense, provide COBRA benefits to Mr. Haden for no
longer than 18 months following a change in control, provided he is eligible for
such benefits.
 
     TOM ANDERSON
 
     VRB has an agreement with Tom Anderson, Executive Vice President, to
provide at VRB's expense, a term life insurance policy on Mr. Anderson's life in
the amount of $350,000, through the year 2002, and at $150,000 thereafter. The
ownership and right to name the beneficiary under said policy is reserved to Mr.
Anderson. VRB has also provided an additional policy for $25,000 of death
benefits on Mr. Anderson's life. The premiums paid by VRB, are included as
taxable compensation income to Mr. Anderson and are reported as such. The cost
of providing these additional two policies was less than $1,000 during 1996.
This benefit is in addition to group life insurance provided to all employees.
 
     The agreement with Mr. Anderson additionally provides for a "change in
control" payment equal to his base salary plus any cash bonuses or other
compensation paid to or for his benefit, during the fiscal year preceding the
Change in Control. Further, if Mr. Anderson leaves VRB following a Change in
Control, VRB will, at its expense, provide COBRA benefits to Mr. Anderson for no
longer than 18 months following a change in control, provided he is eligible for
such benefits.
 
STOCK OPTION PLANS
 
     VRB has two non-qualified stock option plans which were approved by the
shareholders during 1991, and amended in 1994. The plans reserved an aggregate
of 725,492 shares of VRB's unissued Common Stock for grants to employees and
non-employee Directors. The purchase price of the optioned shares is equal to
not less than the book value of a share of stock as of the end of the most
recently completed fiscal year. Options granted are exercisable for ten years
from the date of grant, with shares fully vested after six months for Directors
and up to a ten year period for employees.
 
     The purpose of these plans is to advance the interests of VRB and its
shareholders by enabling VRB to attract and retain the services of people with
training, experience and ability to serve as outside Directors and employees,
and to provide additional incentive to key employees and Directors of VRB by
giving them an opportunity to participate in the ownership and growth of VRB.
 
     During 1996, 10,500 options were contractually committed to employees for
the purchase of VRB Common Stock under the 1994 Amended Non-Qualified Stock
Option Plan for employees. No grants were awarded to any of the named executive
officers in 1996.
 
     Option covering 21,260 shares were awarded to Directors in January, 1996,
under the 1994 Amended Non-Discretionary Stock Option Plan for Non-Employee
Directors.

(2) On December 31, 1996 the market price of VRB's Common Stock was $5.88 per
    share. For purposes of the foregoing table, all stock options 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 this amount
    and the exercise price of the stock option multiplied by the number of
    shares covered by the stock option.
 
(3) On October 17, 1996, the date of exercise, the market price of VRB's Common
    Stock was $6.53 per share.

RELATED TRANSACTIONS WITH DIRECTORS AND OFFICERS
 
     Some of the directors and officers of VRB and members of their immediate
families and firms and corporations with which they are associated, have been
parties to transactions with VRB, 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 June 30, 1997, the aggregate outstanding amount of
all loans to officers and directors was approximately $1,409,000, which
represented approximately 6.5% of VRB's consolidated shareholders' equity at
that date. All such loans are currently in good standing and are being paid in
accordance with their terms.
 
                           SUPERVISION AND REGULATION
 
GENERAL
 
     VRB is extensively regulated under federal and state law. These laws and
regulations are intended to protect depositors, 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 VRB. The operations of VRB may
be affected by legislative changes and by the policies of various regulatory
authorities. VRB cannot 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 BANK HOLDING COMPANY REGULATION
 
     VRB Bancorp is a bank holding company within the meaning of the Bank
Holding Company Act of 1956, as amended ("BHCA"), and as such, it is subject to
regulation, supervision and examination by the Board of Governors of the Federal
Reserve System (the "Federal Reserve"). VRB Bancorp is required to file annual
reports with the Federal Reserve and to provide the Federal Reserve such
additional information as the Federal Reserve may require.
 
     The BHCA requires every bank holding company to obtain the prior approval
of the Federal Reserve before (i) acquiring, directly or indirectly, ownership
or control of any voting shares of another bank or bank holding company if,
after such acquisition, it would own or control more than 5% of such shares
(unless it already owns or controls the majority of such shares); (ii) acquiring
all or substantially all of the assets of another bank or bank holding company;
or (iii) merging or consolidating with another bank holding company. The Federal
Reserve will not approve any acquisition, merger or consolidation that would
have a substantial anti-competitive result, unless the anti-competitive effects
of the proposed transaction are clearly outweighed by a greater public interest
in meeting the convenience and needs of the community to be served. The Federal
Reserve also considers capital adequacy and other financial and managerial
factors in reviewing acquisitions or mergers.
 
     With certain exceptions, the BHCA also prohibits a bank holding company
from acquiring or retaining direct or indirect ownership or control of more than
5% of the voting shares of any company which is not a bank or bank holding
company, or from engaging directly or indirectly in activities other than those
of
 
                                       45
<PAGE>   47
 
banking, managing or controlling banks, or providing services for its
subsidiaries. The principal exceptions to these prohibitions involve certain
non-bank activities which, by statute or by Federal Reserve regulation or order,
have been identified as activities closely related to the business of banking or
of managing or controlling banks. In making this determination, the Federal
Reserve considers whether the performance of such activities by a bank holding
company can be expected to produce benefits to the public such as greater
convenience, increased competition or gains in efficiency in resources, which
can be expected to outweigh the risks of possible adverse effects such as
decreased or unfair competition, conflicts of interest or unsound banking
practices.
 
     Subsidiary banks of a bank holding company are subject to certain
restrictions imposed by the Federal Reserve Act on extensions of credit to the
bank holding company or its subsidiaries, on investments in their securities and
on the use of their securities as collateral for loans to any borrower. These
regulations and restrictions may limit VRB Bancorp's ability to obtain funds
from Valley of the Rogue Bank for its cash needs, including funds for payment of
dividends, interest and operating expenses. Further, under the Federal Reserve
Act and certain regulations of the Federal Reserve, a bank holding company and
its subsidiaries are prohibited from engaging in certain tying arrangements in
connection with any extension of credit, lease or sale of property or furnishing
of services. For example, Valley of the Rogue Bank may not generally require a
customer to obtain other services from it or VRB Bancorp, and may not require
that the customer promise not to obtain other services from a competitor, as a
condition to an extension of credit to the customer.
 
FEDERAL AND STATE BANK REGULATION
 
     Valley of the Rogue Bank, as a state chartered bank with deposits insured
by the FDIC are subject to the supervision and regulation of the Oregon Director
and of the FDIC. These agencies may prohibit the banks from engaging in what
they believe constitute unsafe or unsound banking practices.
 
     The Community Reinvestment Act ("CRA") requires that, in connection with
examinations of financial institutions within their jurisdiction, the Federal
Reserve or the FDIC evaluates 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
banks. These factors are also considered in evaluating mergers, acquisitions and
applications to open a branch or facility. Valley of the Rogue Bank's current
CRA rating is "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 covered above and who are not employees, 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.
 
     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 systems and internal audit systems, loan
documentation, credit underwriting, interest rate exposure, asset growth,
compensation, fees and benefits, such other operational and managerial standards
as the agency determines to be appropriate, 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 believes
that Valley of the Rogue Bank meets all the standards, and therefore does not
believe that these regulatory standards materially affect VRB's business
operations.
 
                                       46

DEPOSIT INSURANCE
 
     The deposits of VRB are currently insured to a maximum of $100,000 per
depositor through the Bank Insurance Fund ("BIF") administered by the FDIC. VRB
is required to pay semiannual deposit insurance premium assessments to the FDIC.
 
     The FDICIA included provisions to reform the Federal deposit insurance
system, including the implementation of risk-based deposit insurance premiums.
The FDICIA also permits the FDIC to make special assessments on insured
depository institutions in amounts determined by the FDIC to be necessary to
give it adequate assessment income to repay amounts borrowed from the U.S.
Treasury and other sources or for any other purpose the FDIC deems necessary.
Pursuant to the FDICIA, the FDIC implemented a risk-based insurance premium
system on January 1, 1993. Generally, under this system, banks are assessed
insurance premiums according to how much risk they are deemed to present to 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. The premium range is from $.00, for the
highest-rated institutions (subject to a statutory minimum assessment of
$2,000), to $.27 per $100 of domestic deposits. The Bank has a current FDIC
premium rate of $.00 per $100 of domestic deposits.
 
DIVIDENDS
 
     The principal source of VRB's cash revenues is dividends received from the
Bank. Under the Oregon Bank Act, the Bank is subject to restrictions on the
payment of cash dividends to its shareholders. 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 amount
of the dividend may not be greater than its net unreserved retained earnings,
after first deducting (i) to the extent not already charged against earnings or
reflected in a reserve, all bad debts, which are debts on which interest is
unpaid and past due at least six months; (ii) all other assets charged off as
required by the Oregon Director or state or federal examiner; and (iii) all
accrued expenses, interest and taxes of the bank. The Bank has been paying
regular dividends to VRB, which has in turn been paying regular dividends to its
shareholders, although no assurances can be given that dividends will continue
to be paid. See "Market Price of and Dividends on Common Stock."
 
     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. VRB and the Bank are not
currently subject to any regulatory restrictions on their dividends other than
those noted above.
 
CAPITAL ADEQUACY
 
     The federal bank regulatory agencies use capital adequacy guidelines in
their examination and regulation of bank holding companies and banks. If the
capital falls below the minimum levels established by these guidelines, the bank
holding company or bank may be denied approval to acquire or establish
additional banks or non-bank businesses or to open facilities.
 
     The FDIC and Federal Reserve have adopted risk-based capital guidelines for
banks and bank holding companies. The risk-based capital guidelines are designed
to make regulatory capital requirements more sensitive to differences in risk
profile among banks and bank 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
guidelines are minimums, and the Federal Reserve has noted that bank holding
companies contemplating significant expansion programs should not allow
expansion to diminish their capital ratios and should maintain ratios well in
excess of the minimum. The current guidelines require all bank 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.
 
     Tier 1 capital for bank holding companies includes common shareholders'
equity, qualifying perpetual preferred stock (up to 25% of total Tier 1 capital,
if cumulative; under a Federal Reserve rule, redeemable
 
                                       47
<PAGE>   49
 
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.
 
     Banks' and bank holding companies' 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 United States Treasury or United
States 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 Federal Reserve 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 holding
company may leverage its equity capital base. The Federal Reserve requires a
minimum leverage ratio of 3%. However, for all but the most highly rated bank
holding companies and for bank holding companies seeking to expand, the Federal
Reserve expects an additional cushion of at least 1% to 2%.
 
     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" depending on the category to which they are
assigned are subject to certain mandatory supervisory corrective actions. VRB
does not believe that these regulations have any material effect on its
operations.
 
EFFECTS OF GOVERNMENT MONETARY POLICY
 
     The earnings and growth of VRB 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, but 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, 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 VRB or the
Bank cannot be predicted with certainty.
 
CHANGING REGULATORY STRUCTURE OF THE BANKING INDUSTRY
 
     The laws and regulations affecting banks and bank holding companies are
currently undergoing significant changes. Bills are now pending or expected to
be introduced in the United States Congress that contain proposals for altering
the structure, 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
 
                                       48
<PAGE>   50
 
business, limiting or expanding permissible activities (including activities in
the insurance and securities fields), or affecting the competitive balance among
banks, savings associations, and other financial institutions. Some of these
bills would reduce the extent of federal deposit insurance, broaden the powers
or the geographical range of operations of bank holding companies, after the
extent of which, Banks will be permitted to engage in securities activities, 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 VRB 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 bank holding company may acquire banks in any state if permitted by
state law. In addition, banks may merge 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 bank holding company may merge with or acquire an Oregon state chartered bank
or bank holding company if the Oregon bank, or in the case of a bank 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 in 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 bank may
open additional branches.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The Articles of Incorporation of VRB Bancorp authorize the issuance of up
to 10 million shares of Common Stock with no par value. As of
1997, there were           shares of Common Stock issued and outstanding.
Subject to the rights of holders of any preferred stock which may be
outstanding, the holders of the Common Stock are entitled to receive dividends
if and when declared by the Board of Directors from any funds legally available
therefor. Each outstanding share of Common stock has the same relative rights
and preferences as each other share of Common Stock, including the rights to the
net assets of the corporation 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.
 
     The Articles of Incorporation authorize the issuance of up to 5 million
shares of voting preferred stock and up to 5 million shares of non-voting
preferred stock. As of                , 1997, there were no outstanding shares
of either class of preferred stock.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
     Under the Oregon Business Corporation Act, a corporation's Articles of
Incorporation may provide for limitation of liability of directors and
indemnification of directors and officers under certain circumstances. In
accordance with Oregon law, 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 also provide for indemnification of any
person who is or was 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 corporation or any of its subsidiaries, or
is or was serving at the request of the corporation as a director, officer,
partner, agent or employee of another corporation or entity, against expenses,
including attorneys' fees, judgments, fines and amounts paid in settlement,
actually and reasonably incurred by that person if (i) the person acted in good
faith and in a manner reasonably believed to not be opposed to the best
interests of the corporation, or (ii) the act or omission giving rise to such
action or proceeding is ratified, adopted or confirmed by the corporation, or
the benefit thereof was received by the corporation. Indemnification is
available under this provision of the Articles of Incorporation in the case of
 
                                       49
<PAGE>   51
 
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 corporation. 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.
 
ANTI-TAKEOVER PROVISIONS
 
     The Company is subject to the Oregon Control Share Act (Oregon Revised
Statutes Sections 60.801-60.816)(the "Control Share Act"). The Control Share Act
generally provides that a person (the "Acquiring Person") who acquires voting
stock of an Oregon corporation in a transaction which results in such Acquiring
Person holding more than 20%, 33 1/3% or 50% of the total voting power of such
corporation (a "Control Share Acquisition") cannot vote the shares it acquires
in the Control Share Acquisition ("control shares") unless voting rights are
accorded to such control shares by the holders of a majority of the outstanding
voting shares, excluding the control shares held by the Acquiring Person and
shares held by the Company's officers and inside directors ("interested
shares"), and by the holders of a majority of the outstanding voting shares,
including interested shares. The foregoing vote would be required at the time an
Acquiring Person's holdings exceed 20% of the total voting power of a company,
and again at the time the Acquiring Person's holdings exceed 33 1/3% and 50%,
respectively. The term "Acquiring Person" is broadly defined to include persons
acting as a group. A transaction in which voting power is acquired solely by
receipt of an immediately revocable proxy does not constitute a "Control Share
Acquisition."
 
     The Acquiring Person may, but is not required to, submit to the Company an
"Acquiring Person Statement" setting forth certain information about the
Acquiring Person and its plans with respect to the Company. The Acquiring Person
Statement may also request that the Company call a special meeting of
shareholders to determine whether the control shares will be allowed to retain
voting rights. If the Acquiring Person does not request a special meeting of
shareholders, the issue of voting rights of control shares will be considered at
the next annual meeting or special meeting of shareholders that is held more
than 60 days after the date of the Control Share Acquisition. If the Acquiring
Person's control shares are accorded voting rights and represent a majority or
more of all voting power, shareholders who do not vote in favor of the
restoration of such voting rights will have the right to receive the appraised
"fair value" of their shares, which may not be less than the highest price paid
per share by the Acquiring Person for the control shares.
 
     The Company is also subject to the Oregon Business Combination Act (Oregon
Revised Statutes Sections 60.825-60.845)(the "Business Combination Act"). The
Business Combination Act generally provides that in the event a person or entity
acquires 15% or more of the voting stock of an Oregon corporation (an
"Interested Shareholder"), the corporation and the Interested Shareholder, or
any affiliated entity, may not engage in certain business combination
transactions for a period of three years following the date the person became an
Interested Shareholder. Business combination transactions for this purpose
include (a) a merger or plan of share exchange, (b) any sale, lease, mortgage or
other disposition of the assets of the corporation where the assets have an
aggregate market value equal to 10% or more of the aggregate market value of the
corporation's assets or outstanding capital stock, and (c) certain transactions
that result in the issuance of capital stock of the corporation to the
Interested Shareholder. These restrictions do not apply if (i) the Interested
Shareholder, as a result of the transaction in which such person became an
Interested Shareholder, owns at least 85% of the outstanding voting stock of the
corporation (disregarding shares owned by directors who are also officers, and
certain employee benefit plans), (ii) the Board of Directors approves the share
acquisition or business combination before the Interested Shareholder acquired
15% or more of the corporation's voting stock, or (iii) the Board of Directors
and the holders of at least two-thirds of the outstanding voting stock of the
corporation (disregarding shares owned by the Interested Shareholder) approve
the transaction after the Interested Shareholder acquires 15% or more of the
corporation's voting stock.
 
     The Control Share Act and the Business Combination Act will have the effect
of encouraging any potential acquiror to negotiate with the Company's Board of
Directors and will also discourage certain potential acquirors unwilling to
comply with its provisions. A corporation may provide in its articles of
 
                                       50

incorporation or bylaws that the laws described above do not apply to its
shares. the Company has not adopted such a provision and does not currently
intend to do so. The law may make VRB less attractive for takeover, and thus
shareholders may not benefit from a rise in the price of the Common Stock that a
takeover could cause. The limitations of the Acts are in addition to regulatory
restrictions on acquisitions of stock of banks and bank holding companies under
the federal Bank Holding Company Act.
 
     In addition to the statutory provisions discussed above, the Company's
articles of incorporation contain certain provisions that could make more
difficult the acquisition of the Company by means of a tender offer, proxy
contest, merger or otherwise. The articles of incorporation authorize the
issuance of up to 5,000,000 shares of voting preferred stock, which, although
intended primarily as a financing tool and not as a defense against takeovers,
could potentially be used by Management to make more difficult uninvited
attempts to acquire control of the Company by, for example, diluting the
ownership interest of a substantial shareholder, increasing the consideration
necessary to effect an acquisition, or selling authorized but 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 Company.
 
     Finally, the Company is subject to the reporting requirements of, and its
common stock is registered under, the Securities Exchange Act of 1934. Any
person who acquires the Company common stock, and after giving effect to such
acquisition, holds more than 5% of the outstanding shares, is required to report
such acquisition to the Securities and Exchange Commission under section 13 of
the Securities Exchange Act. Thus, a person contemplating acquiring control will
be obligated to make public such person's intentions, even prior to being
required to report such transactions to the Federal Reserve under the Bank
Holding Company Act. See "Supervision and Regulation."
 
TRANSFER AGENT
 
     The transfer agent and registrar of the Common Stock is Valley of the Rogue
Bank.

     The Underwriting Agreement provides that the obligations of the
Underwriters to purchase the shares of Common Stock listed above are subject to
the approval of certain legal matters by counsel and various other conditions.
The Underwriting Agreement also provides that the Underwriters are committed to
purchase all of the shares of Common Stock offered hereby, if any are purchased
(except for any shares that may be purchased through exercise of the
underwriters' over-allotment option which may be exercised by the Underwriters
in whole or in part).
 
     The Representative has advised VRB that the Underwriters propose to offer
the shares of Common Stock to the public at the public offering price set forth
on the cover of this Prospectus and to certain dealers at such price less a
concession not in excess of $          per share. After the Offering, the public
offering price and other selling terms may be changed by the Representatives.
The Common Stock is offered subject to receipt and acceptance by the
Underwriters, and to certain other conditions, including the right to reject
orders in whole or in part.
 
     Prior to this Offering, there has been only a limited public market for the
Common Stock. Accordingly, the public offering price has been determined by
negotiation between VRB and the Representative. Among the factors considered in
determining the public offering price were the recent bid prices quoted by
market makers in the Common Stock, VRB's present and historical results of
operations, VRB's current financial condition, estimates of the business
potential and prospects of VRB, economic conditions in VRB's market area, the
experience of VRB's Management, the economics of the industry in general, the
general condition of the equity markets at the time of the Offering and other
relevant factors. There can be no assurance that an active trading market will
develop for the Common Stock, that purchasers in the Offering will be able to
sell their shares at or above the Offering price, or as to the price at which
the Common Stock may trade in the public market from time to time subsequent to
the Offering.
 
     VRB has granted the Underwriters an option, exercisable during the 30-day
period after the date of this Prospectus, to purchase up to 150,000 additional
shares of Common Stock at the public offering price set forth on the cover page
of this Prospectus, less underwriting discounts and commissions. To the extent
the Underwriters exercise the option, each Underwriter will have a firm
commitment, subject to certain conditions, to purchase such number of additional
shares of Common Stock as is proportionate to such Underwriter's initial
commitment to purchase shares from VRB. The Underwriters may exercise such
option solely to cover over-allotments, if any, incurred in connection with the
sale of shares of Common Stock offered hereby.
 
                                       52
<PAGE>   54
 
     The Underwriting Agreement provides that VRB has agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
     All of VRB's executive officers and directors have agreed that, for a
period of 180 days after the day on which the Registration Statement becomes
effective by order of the Commission, they will not, without the prior written
consent of Black & Company, Inc. directly or indirectly, offer for sale, sell,
contract to sell, or grant any option to sell (including, without limitation,
any short sale), pledge, establish an open "put-equivalent position" within the
meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, transfer,
assign or otherwise dispose of any shares of VRB's Common Stock or securities
exchangeable for or convertible into shares of VRB's Common Stock, or any
option, warrant or other right to acquire such shares, or publicly announce the
intention to do any of the foregoing.
 
     During and after the offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the offering. Stabilizing transactions consist of
certain bids or purchases for the purpose of preventing or retarding a decline
in the market price of the Common Stock; and syndicate share positions involve
the sale of the Underwriters of a greater number of shares of Common Stock than
they are required to purchase from VRB in the offering. The Underwriters also
may impose a penalty bid, whereby selling concessions allowed to syndicate
members or other broker-dealers in respect of the Common Stock sold in the
offering for their account may be reclaimed by the syndicate if such securities
are repurchased by the syndicate in stabilizing or covering transactions. These
activities may stabilize, maintain or otherwise affect the market price of the
Common Stock which may be higher than the price that might otherwise prevail in
the open market, and these activities, if commenced, may be discontinued at any
time. These transactions may be effected on the Nasdaq National Market, in the
over-the-counter market or otherwise.
 
     The Representatives have advised VRB that the Underwriters do not intend to
confirm sales of Common Stock offered by this Prospectus made to any accounts
over which they exercise discretionary authority.
 
     VRB has applied for inclusion of the Common Stock on the Nasdaq National
Market under the symbol "VRBA."
 
     The foregoing is a brief summary of the provisions of the Underwriting
Agreement and does not purport to be a complete statement of its terms and
conditions. A copy of the form of Underwriting Agreement has been filed as an
exhibit to the Registration Statement.

                          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, 1995 and 1996, and the related statements of income, changes in
shareholders' equity, and cash flows for each of the years ended December 31,
1994, 1995, and 1996. 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 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 VRB Bancorp as of
December 31, 1995 and 1996, and the results of its operations and cash flows for
each of the years ended December 31, 1994, 1995, and 1996, in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       DECEMBER 31, 1994, 1995, AND 1996
 
NOTE 1 -- DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT
          ACCOUNTING POLICIES
 
     DESCRIPTION OF BUSINESS -- 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 Bancorp is conducted through its subsidiary
bank and all significant intercompany accounts and transactions have been
eliminated in the preparation of the consolidated financial statements.
 
     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 ASSUMPTIONS -- In preparing the consolidated
financial statements, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and liabilities at the date of the financial statements, and
the reported amounts of 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,
1995 and 1996, are either "available-for-sale" or "held-to-maturity" and conform
to the following accounting policies:
 
          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 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.
 
          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.
 
     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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
     Impaired loans are carried at the present value of expected future cash
flows discounted at the loan's effective interest rate, the loan's market price
or the fair value of the collateral if the loan is collateral dependent. 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 for furniture and equipment; 15 to 40
years for buildings and components; and, 15 to 20 years for leasehold
improvements.
 
     OTHER REAL ESTATE -- Other real estate, acquired through foreclosure or
deeds in lieu of foreclosure, 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 reserve 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. The Bank had no other
real estate at December 31, 1995 and 1996.
 
     INTANGIBLE ASSETS -- Intangible assets consist of purchased goodwill
arising from the previous acquisition of financial institutions. These assets
are being amortized over periods which do not exceed 15 years.
 
     INCOME TAXES -- 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 -- In the ordinary course of
business, the Bank has entered 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.
 
     The Financial Accounting Standards Board (FASB) issued Statement No. 119,
"Disclosures about Derivative Financial Instruments and Fair Value of Financial
Instruments" which became effective for the Bank for the year ending December
31, 1995. This pronouncement requires that banks holding derivative financial
instruments disclose quantitative and qualitative information about the
instruments. As of December 31, 1995 and 1996, and for the years then ended, the
Bank held no derivative financial instruments.

                                  VRB BANCORP
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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), 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 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.
 
     STOCK OPTIONS -- In October 1995 the FASB issued Statement of Financial
Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation."
This new standard defines a fair-value based method of accounting for an
employee stock option or similar equity instrument.
 
     This statement gives entities a choice of recognizing related compensation
expense by adopting the new fair value method or to continue to measure
compensation using the intrinsic value approach under Accounting Principles
Board (APB) Opinion No. 25, the former standard. If the former standard for
measurement were elected, SFAS No. 123 requires supplemental disclosure to show
the effects of using the new measurement criteria. The Bank has elected to
continue using the measurement prescribed by APB Opinion No. 25, and
accordingly, this pronouncement has had no effect on the Bank's financial
position or results of operations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     UNAUDITED INTERIM FINANCIAL DATA -- The interim financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management all adjustments,
including normal recurring accruals necessary for fair presentation of results
of operations for the interim periods included herein, have been made. The
results of operations for the six months ended June 30, 1997, are not
necessarily indicative of results to be anticipated for the year ending December
31, 1997.
 
     RECENTLY ISSUED ACCOUNTING STANDARDS -- In June 1996, the FASB issued SFAS
No. 125, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishment of Liabilities" which the Bank is required to adopt for the year
ended December 31, 1997. SFAS No. 125 requires that the Bank recognize the
financial and servicing assets it controls and the liabilities it has incurred,
derecognize financial assets when control has been surrendered, and derecognize
liabilities when extinguished. The Bank's management has determined that the
adoption of this statement will not have a material impact on its consolidated
financial statements.
 
     In February 1997, the FASB issued SFAS No. 128 "Earnings Per Share" which
the Bank is required to adopt for both interim and annual periods ending after
December 15, 1997. This statement specifies the computation, presentation, and
disclosure requirements of earnings per share. Management has not yet determined
the effect of the adoption of this statement on the consolidated earnings per
share calculation for the Bank, but does not anticipate that it will be
material.
 
     In February 1997, the FASB issued SFAS No. 129 "Disclosure of Information
about Capital Structure" which requires that the Bank describe, in the financial
statements, the pertinent rights and privileges of the various securities
outstanding. This will become effective for the year ended December 31, 1998,
and will have no significant impact on disclosures to the consolidated financial
statements.
 
     In June 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive Income"
which the Bank is required to adopt for years beginning after December 15, 1997.
This statement establishes standards for reporting and display of comprehensive
income and its components (revenues, expenses, gains, and losses) in a full set
of general purpose financial statements. When adopted, the unrealized gain or
loss on available-for-sale securities will be recognized as a component of
comprehensive income.
 
     Other issued but not yet required FASB statements are not currently
applicable to the Bank's operations.

     Proceeds from maturities and calls of held-to-maturity investment
securities during 1995 and 1996, were $7,896,000 and $5,390,000, respectively.
Proceeds from the sales and maturities of available-for-sale securities were
$2,000,000 and $6,118,000 in 1995 and 1996, respectively.
 
     During 1995, pursuant to implementation guidance on accounting for certain
investments in debt and equity securities issued in a Special Report by the
Financial Accounting Standards Board, the Bank reassessed the appropriateness of
its classifications for investment securities. Accordingly, securities with an
amortized cost of $16,238,000 were transferred from the held-to-maturity
category to the available-for-sale category. This resulted in the recognition of
an unrealized loss on available-for-sale securities, net of tax, of $133,000 at
the time of transfer.

     Impaired loans of $52,000 and $58,000 at December 31, 1995 and 1996,
respectively, have been recognized in conformity with FASB Statement No. 114, as
amended by FASB Statement No. 118. The average recorded investment and total
allowance for loan losses related to impaired loans was equal to their recorded
investment at December 31, 1995 and 1996. No interest income was accrued on the
impaired loans or included in the results of operations for the years ended
December 31, 1994, 1995, and 1996. Management estimates that in 1994,
approximately $542 of interest income was not recognized on impaired loans
carried on nonaccrual status, compared with approximately $3,000 in 1995 and
$4,000 in 1996.

     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 Accounting Principles Board 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. The compensation deductions arising
from the exercise of stock options were not material in 1994 and 1995. In the
year ended December 31, 1996, such deductions resulted in federal and state tax
deductions increasing common stock.
 
     Management believes, based upon the Bank's historical performance, 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 the effect of tax exemptions for interest received on municipal
investments. The 1995 provision for income taxes reflects a reduction in the
state income tax rate from 6.6% to 3.3%.

NOTE 8 -- 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 nearly
all 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 held 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.
 
     The Bank has not been required to perform on any financial guarantees
during the past two years. The Bank has not incurred any losses on its
commitments in either 1994, 1995, or 1996.

</TABLE>
 
     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 items at December 31, 1995 and 1996, the estimated fair values
would necessarily have been achieved at that date, since market values may
differ depending on various circumstances. The estimated fair values at December
31, 1995 and 1996, 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, such as premises and equipment, are not included in
the above disclosures. 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 10 -- 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 involve government entities also within the
Bank's geographical region. The concentrations of credit by type of loan are set
forth in Note 3. 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, 1996. 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 $200,000 without approval
from the Board of Directors.

NOTE 11 -- BORROWING AGREEMENTS
 
     The Bank has borrowing agreements with the Bank of America and Wells Fargo
Bank for $2,000,000 and $3,000,000, respectively. There is no stated rate of
interest on these borrowings. As of December 31, 1996, 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 $6,900,000 with interest at the FHLB's cash management rate.
There were no borrowings outstanding at December 31, 1996.
 
NOTE 12 -- COMMITMENTS AND CONTINGENCIES
 
     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.
 
     The Bank leases certain branch premises and equipment. The following is a

     Rental expense for all operating leases was approximately $79,000, $92,000,
and $94,000 in 1994, 1995, and 1996, respectively.
 
NOTE 13 -- 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 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
$20,000, $39,000, and $45,000 as compensation expense relating to 5,000, 7,000,
and 7,000 shares of common stock optioned to its directors during 1994, 1995,
and 1996, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The fair value of each option granted during 1995 and 1996, is estimated on
the date of grant using the Black-Scholes option-pricing model with the
following assumptions: (1) dividend yield of 5.72%, (2) expected volatility of
23%, (3) risk-free rate of 7.5%; and, (4) expected life of 10 years.
 
     The effects of applying SFAS No. 123 in this proforma disclosure are not
indicative of future amounts. SFAS No. 123 does not apply to awards prior to
1995, and additional awards in future years are anticipated.
 
NOTE 14 -- 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 $169,000, $172,000, and $162,000 in 1994, 1995, and 1996,
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 $154,000, $171,000, and $186,000
in 1994, 1995, and 1996, respectively.
 
     The Bank has established a bonus program as part of the compensation
package it provides to employees. At December 31, 1996, the Bank employed
approximately 120 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 proceeding year. An executives' bonus
program is similarly funded and based on current year profits with payments
measured on the basis of return on assets on after-tax income. For the years
ending December 31, 1994, 1995, and 1996, $453,000, $600,000, and $510,000,
respectively, was expensed to fund these programs with their related payroll and
benefit costs.
 
     The Bank has also established supplemental retirement agreements with
certain of its 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, 1996, a liability for the supplemental retirement plans was recognized and
funded in the amount of $256,000. During 1994, 1995, and 1996, the Bank recorded
Plan expenses of $42,000, $42,000, and $28,000, respectively.
 
NOTE 15 -- EARNINGS PER COMMON AND COMMON EQUIVALENT SHARES
 
     Earnings per share were computed by dividing net income by the weighted
average number of shares of common stock and common stock equivalents
outstanding for the years ending December 31, 1994, 1995, and 1996. Common stock
equivalents include the number of shares issuable on exercise of the outstanding
options less the numbers of shares that would have been purchased with the
proceeds from the exercise of the options based on the average price of common
stock during the year for primary net income per common share and the closing
market price of common stock for fully diluted net income per common share.
There is no difference between primary and fully diluted net income per common
share calculations for the years ended December 31, 1994, 1995, and 1996.
 
NOTE 16 -- TRANSACTIONS WITH RELATED PARTIES
 
     Certain directors, executive officers, and principal shareholders 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

NOTE 17 -- REGULATORY MATTERS
 
     The Bank is 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 the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off-balance-sheet items as calculated under regulatory
accounting practices. The Bank's 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 the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital to average assets (as
defined). Management believes, as of December 31, 1996, that the Bank meets all
capital adequacy requirements to which it is subject.
 
     As of December 31, 1996, the most recent notification from regulatory
examiners categorized the Bank as adequately capitalized under the regulatory
framework for prompt corrective action. To be categorized as adequately
capitalized the Bank must maintain minimum total risk-based, Tier I risk-based,
and Tier I 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.
 
     The Bank's actual capital amounts and ratios are also presented in the
following table (in thousands):

                          INDEPENDENT AUDITOR'S REPORT
 
To the Board of Directors
  and shareholders of Colonial Banking Company
 
     We have audited the accompanying balance sheets of Colonial Banking Company
as of December 31, 1995 and 1996, and the related statements of income, changes
in shareholders' equity, and cash flows for the years ended December 31, 1994,
1995, and 1996. These financial statements are the responsibility of Colonial
Banking Company'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 financial statements referred to above present fairly,
in all material respects, the financial position of Colonial Banking Company as
of December 31, 1995 and 1996, and the results of its operations and cash flows
for the years ended December 31, 1994, 1995, and 1996, in conformity with
generally accepted accounting principles.
 
     As discussed in Note 18, the accompanying financial statements as of
December 31, 1995 and 1996, and for the years ended December 31, 1994, 1995, and
1996, have been restated to reflect prior period adjustments related to the
allowance for loan losses.

                         NOTES TO FINANCIAL STATEMENTS
                       DECEMBER 31, 1994, 1995, AND 1996
 
NOTE 1 -- DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     DESCRIPTION OF BUSINESS -- Colonial Banking Company (the Bank) is a
majority owned subsidiary of Investors Banking Corporation (IBC). The Bank
conducts a general banking business. Its activities include the usual deposit
functions of a commercial bank: commercial, real estate, installment, credit
card and mortgage loans; checking and savings accounts; automated teller
machines (ATM's); collection services; and safe deposit facilities. The Bank
also originates and sells mortgage loans into the secondary market.
 
     The Bank is a state-chartered institution authorized to provide banking
services by the State of Oregon. With its headquarters in Grants Pass, Oregon,
the Bank also has branch operations in Josephine and Jackson County, Oregon. The
Bank is subject to the regulations of certain Federal and State agencies and
undergoes periodic examinations by those regulatory authorities.
 
     MANAGEMENT'S ESTIMATES AND ASSUMPTIONS -- In preparing its financial
statements, management is required to make estimates and assumptions that affect
the reported amounts of assets and liabilities, the disclosure of contingent
assets and liabilities at the date of the financial statements, and the reported
amounts of 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,
1995 and 1996, are "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.
 
     Declines in the fair value of individual held-to-maturity 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.
 
     Impaired loans are carried at the present value of expected future cash
flows discounted at the loan's effective interest rate, the loan's market price
or the fair value of the collateral if the loan is collateral dependent. Accrual
of interest is discontinued on a loan 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 accrued is discontinued, all unpaid

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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 of the yield of the related loan.
 
     MORTGAGE LOANS -- Mortgage loans held-for-sale are carried at the lower of
cost or estimated market value. Market value is determined on an aggregate loan
basis. At December 31, 1995 and 1996, mortgage loans held-for-sale were carried
at cost which approximated market.
 
     PREMISES AND EQUIPMENT -- Premises and equipment are stated at cost, less
accumulated depreciation and amortization. Depreciation and amortization is
computed on straight-line and accelerated methods over the shorter of the
estimated useful lives of the assets or terms of the leases. Amortization of
leasehold improvements is included with depreciation expense in the accompanying
financial statements.
 
     OTHER REAL ESTATE -- Other real estate, acquired through foreclosure or
deeds in lieu of foreclosure, is carried at the lower of cost or estimated net
realizable value. When the property is acquired, any excess of the loan balance
over the estimated net realizable value is charged to the reserve 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.
Other real estate was insignificant at December 31, 1995 and 1996.
 
     INCOME TAXES -- 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 -- In the ordinary course of
business, the Bank has entered 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.
 
     The Financial Accounting Standards Board (FASB) issued Statement No. 119,
"Disclosures about Derivative Financial Instruments and Fair Value of Financial
Instruments" which became effective for the Bank for the year ending December
31, 1995. This pronouncement requires that banks holding derivative financial
instruments disclose quantitative and qualitative information about the
instruments. As of December 31, 1995 and 1996, and for the years then ended, the
Bank held no derivative financial instruments.
 
     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 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 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 generally charged to expense during
the year in which they are incurred.
 
     STOCK OPTIONS -- In October 1995 the FASB issued Statement of Financial
Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation."
This new standard defines a fair-value based method of accounting for an
employee stock option or similar equity instrument.
 
     This statement gives entities a choice of recognizing related compensation
expense by adopting the new fair value method or to continue to measure
compensation using the intrinsic value approach under Accounting Principles
Board (APB) Opinion No. 25, the former standard. If the former standard for
measurement were elected, SFAS No. 123 requires supplemental disclosure to show
the effects of using the new measurement criteria. The Bank has elected to
continue using the measurement prescribed by APB Opinion No. 25, and
accordingly, this pronouncement has had no effect on the Bank's financial
position or results of operations.
 
     UNAUDITED INTERIM FINANCIAL DATA -- The interim financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all
adjustments, including normal recurring accruals necessary for fair presentation
of results of operations for the interim periods included herein, have been
made. The results of operations for the six months ended June 30, 1997, are not
necessarily indicative of results to be anticipated for the year ending December
31, 1997.
 
     ACCOUNTING STANDARDS YET TO BE ADOPTED -- In June 1996, the FASB issued
SFAS No. 125, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishment of Liabilities" which the Bank is required to adopt for the year
ended December 31, 1997. SFAS No. 125 requires that the Bank recognize the
financial

and servicing assets it controls and the liabilities it has incurred,
derecognize financial assets when control has been surrendered, and derecognize
liabilities when extinguished. The Bank's management has determined that the
adoption of this statement will not have a material impact on its financial
statements.
 
     In February 1997, the FASB issued SFAS No. 128 "Earnings Per Share" which
the Bank is required to adopt for both interim and annual periods ending after
December 15, 1997. This statement specifies the computation, presentation, and
disclosure requirements of earnings per share. Management has not yet determined
the effect of the adoption of this statement on the earnings per share
calculation for the Bank, but does not anticipate that it will be material.
 
     In February 1997, the FASB issued SFAS No. 129 "Disclosure of Information
about Capital Structure" which requires that the Bank describe, in the financial
statements, the pertinent rights and privileges of the various securities
outstanding. This will be effective for the year ended December 31, 1998, and
will have no significant impact on disclosures to the financial statements.
 
     In June 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive Income"
which the Bank is required to adopt for years beginning after December 15, 1997.
This statement establishes standards for reporting and display of comprehensive
income and its components (revenues, expenses, gains, and losses). Management
expects this standard, when adopted, will have no material impact on the Bank's
financial statements.
 
     Other issued but not yet required FASB statements are not currently
applicable to the Bank's operations.
 
     RECLASSIFICATIONS -- Certain reclassifications have been made to the 1994
and 1995 financial statements to conform with current year presentations.

     The tax provision differs from the federal statutory rate of 34% due
principally to the effect of tax exemptions for interest received on municipal
investments. The 1995 provision for income taxes reflects a reduction in the
state income tax rate from 6.6% to 3.3%.
 
     A reconciliation between the statutory federal income tax rate and the

NOTE 8 -- 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
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 nearly all 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 held 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.
 
     The Bank has not been required to perform on any financial guarantees
during the past two years. The Bank has not incurred any losses on its
commitments in either 1994, 1995, or 1996.
 
     A summary of the notional amounts of the Bank's financial instruments with

     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 items at December 31, 1995 and 1996, the estimated fair values
would necessarily have been achieved at that date, since market values may
differ depending on various circumstances. The estimated fair values at December
31, 1995 and 1996, 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 10 -- CONCENTRATIONS OF CREDIT
 
     The Bank's branches are located in Josephine County and Jackson County,
Oregon, and a substantial portion of the Bank's loans are collateralized by real
estate in this geographic area. In addition, the Bank's loan portfolio includes
a significant portion of real estate secured loans in the Salem, Oregon area
(approximately $18,514,000 and $21,416,000, at December 31, 1995 and 1996,
respectively) and in the Portland, Oregon area (approximately $10,425,000 at
December 31, 1996). The loans outside of the Josephine and Jackson County areas
were either purchased from another financial institution or were generated from
the Bank's loan production office in Portland which was opened in 1996. The
ultimate collectibility of the majority of the Bank's loan portfolio is
particularly susceptible to changes in conditions in these three market areas.
The concentrations of credit by type of loan are set forth in Note 3. 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, 1996. Investments in state
and municipal securities involve government entities within the Bank's
geographical region.
 
NOTE 11 -- BORROWINGS FROM FEDERAL HOME LOAN BANK
 
     At December 31, 1995 and 1996, the Bank had long-term borrowings from the
Federal Home Loan Bank of Seattle (FHLB) totaling $293,000 and $271,000,
respectively, with fixed interest rates ranging from 5.50% to 6.61%. The
borrowings require monthly principal and interest payments and mature from 2008
through 2010. All borrowings from FHLB are collateralized by a blanket pledge
agreement on FHLB stock, funds on deposit with FHLB, investments, and loans.
 
NOTE 12 -- COMMITMENTS AND CONTINGENCIES
 
     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 financial position or results of operations.
 
     The Bank leases certain land and facilities under operating leases, some of
which include renewal options and escalation clauses. At December 31, 1996, the
aggregate minimum rental commitments under operating leases that have initial or
remaining noncancellable lease terms in excess of one year were approximately as
follows (in thousands):

plan (the Stock Plan) for key employees. The Stock Plan provides that the
exercise price of options will be the estimated fair market value at the date of
grant. Generally, options vest and become exercisable over a four-year period
commencing one year from the date of grant.

     The fair value of each option granted during 1995 and 1996, is estimated on
the date of grant using the Balck-Scholes option-pricing model with the
following assumptions: (1) dividend yield of 8.5% on preferred stock; (2)
risk-free interest rate of approximately 6%; and, (3) expected life of two
years.
 
     The effects of applying SFAS No. 123 in this proforma disclosure are not
indicative of future amounts. SFAS No. 123 does not apply to awards prior to
1995, and additional awards in future years are anticipated.
 
NOTE 14 -- EMPLOYEE BENEFIT PLANS
 
     The Bank maintains a profit sharing plan (the Plan) that covers
substantially all employees of the Bank. Contributions to the Plan are made
solely at the discretion of the Board of Directors, and totaled approximately
$25,000, $26,000, and $34,000 in 1994, 1995, and 1996, respectively.
 
NOTE 15 -- EARNINGS PER COMMON AND COMMON EQUIVALENT SHARES
 
     Primary earnings per common share is computed by deducting preferred
dividends from net income in order to determine net income attributable to
common stockholders. This amount is then divided by the weighted average number
of common shares outstanding during the year, giving effect to common stock
equivalents arising from stock options (1994 -- 260,953 shares, 1995 -- 248,390
shares, and 1996 -- 249,651 shares).
 
     Fully diluted earnings per common share is computed by dividing net income
by the weighted average number of common shares outstanding during the year,
after giving effect to common stock equivalents arising from stock options and
for preferred stock assumed to be converted into common stock (1994 -- 307,608,
1995 -- 397,431 shares, and 1996 -- 400,093 shares).
 
NOTE 16 -- 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
directors, executive officers, principal stockholders, and companies with which
they are associated was as follows (in thousands):

NOTE 17 -- REGULATORY MATTERS
 
     The Bank is 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 the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off-balance-sheet items as calculated under regulatory
accounting practices. The Bank's 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 the Bank to maintain minimum amounts and ratios (set forth in the
following table) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital to average assets (as
defined). Management believes, as of December 31, 1996, that the Bank meets all
capital adequacy requirements to which it is subject.
 
     As of December 31, 1996, the most recent notification from regulatory
examiners categorized the Bank as adequately capitalized under the regulatory
framework for prompt corrective action. To be categorized as adequately
capitalized the Bank must maintain minimum total risk-based, Tier I risk-based,
and Tier I 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.
 
     The Bank's actual capital amounts and ratios are also presented in the
following table (in thousands):

     At December 31, 1995, the Bank's preferred stock was considered Tier 2
capital because the Bank's preferred shareholders had not voted to approve that
dividends on preferred stock were noncumulative. During 1996, the Bank held a
special shareholders meeting at which the preferred shareholders voted to
approve the noncumulative nature of the preferred stock. Accordingly, at
December 31, 1996, the Bank's preferred stock is considered Tier 1 capital.

NOTE 18 -- CORRECTION OF UNDERSTATEMENT OF ALLOWANCE FOR LOAN LOSSES
 
     During 1997, management re-evaluated the allowance for loan losses and
adopted a different methodology for determining an appropriate allowance for
loan losses. As a result, prior period adjustments related to the allowance were
made to previously issued financial statements.

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     As an Oregon corporation, the Company is subject to the Oregon Business
Corporation Act (the "Business Corporation Act"). Under the Business Corporation
Act, a corporation may provide in its Articles of Incorporation or in its Bylaws
for the indemnification of directors and officers against liability where the
director or officer has acted in good faith and with a reasonable belief that
actions taken were in the best interests of the corporation or at least not
adverse to the corporation's best interests and, if in a criminal proceeding,
the individual had no reasonable cause to believe that the conduct in question
was unlawful. Under the Business Corporation Act, a corporation may not
indemnify an officer or director against liability in connection with a claim by
or in the right of the corporation in which such officer or director was
adjudged liable to the corporation or in connection with any other proceeding in
which the officer or director was adjudged liable for receiving an improper
personal benefit; however, a corporation may indemnify against the reasonable
expenses associated with such proceeding. A corporation may not indemnify
against breaches of the duty of loyalty. The Business Corporation Act provides
for mandatory indemnification of directors against all reasonable expenses
incurred in the successful defense of any claim made or threatened whether or
not such claim was by or in the right of the corporation. A court may order
indemnification if it determines that the director or officer is fairly and
reasonably entitled to indemnification in view of all the relevant circumstances
whether or not the director or officer met the good faith and reasonable belief
standards of conduct set out in the statute. Unless otherwise stated in the
Articles of Incorporation, officers of the corporation are also entitled to the
benefit of the above statutory provisions.
 
     The Business Corporation Act also provides that the corporation may, by so
providing in its Articles of Incorporation, eliminate or limit the personal
liability of a director to the corporation or its shareholders for monetary
damages for conduct as a director, provided that the Articles of Incorporation
may not eliminate or limit liability for any breach of the director's duty of
loyalty, acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, any unlawful distribution, or any
transaction from which the director received an improper personal benefit.
 
     In accordance with Oregon law, the Articles of Incorporation of the Company
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.
 
                                      II-1
<PAGE>   99
 
     The Articles of Incorporation also provide for indemnification of any
person who is or was 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 corporation or any of its subsidiaries, or
is or was serving at the request of the corporation as a director, officer,
partner, agent or employee of another corporation or entity, against expenses,
including attorneys' fees, judgments, fines and amounts paid in settlement,
actually and reasonably incurred by that person if (i) the person acted in good
faith and in a manner reasonably believed to not be opposed to the best
interests of the corporation, or (ii) the act or omission giving rise to such
action or proceeding is ratified, adopted or confirmed by the corporation, or
the benefit thereof was received by the corporation. 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 corporation. 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.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes that:
 
          (A) The undersigned registrant hereby undertakes to provide to the
     underwriter at the closing specified in the underwriting agreements
     certificates in such denominations and registered in such names as required
     by the Underwriter to permit prompt delivery to each purchaser.
 
          (B) For purposes of determining any liability under the Securities Act
     of 1933, as amended, the information omitted from the form of prospectus
     filed as part of this registration statement in reliance upon Rule 430A and
     contained in a form of prospectus filed by the registrant Rule 424(b)(1) or
     (4), or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared it effective.
 
          (C) For the purpose of determining any liability under the Securities
     Act of 1933, as amended, each post-effective amendment that contains a form
     of prospectus shall be deemed to be a new registration statement relating
     to the securities offered therein and the offering of such securities at
     that time shall be deemed to be the initial bona fide offering thereof.
 
          (D) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933, as amended, (the "Act") may be permitted to
     directors, officers and controlling persons of the registrant pursuant to
     the foregoing provisions, or otherwise, the registrant has been advised
     that in the opinion of the Securities and Exchange Commission such
     indemnification is against public policy as expressed in the Act and is,
     therefore, unenforceable. In the event that a claim for indemnification
     against such liabilities (other than the payment by the registrant of
     expenses incurred or paid by a director, officer or controlling person of
     the registrant in the successful defense of any action, suit or proceeding)
     is asserted by such director, officer or controlling person in connection
     with the securities being registered, the registrant will, unless in the
     opinion of its counsel the matter has been settled by controlling
     precedent, submit to a court of appropriate jurisdiction the question
     whether such indemnification by it is against public policy as expressed in
     the Act and will be governed by the final adjudication of such issue.

                             STOCK OPTION AGREEMENT


         This Stock Option Agreement is entered into by and among Valley of the
Rogue Bank ("VRB"), an Oregon state bank, and the shareholders of Investors
Banking Corporation ("IBC"), effective as of July 24, 1997. The shareholders of
IBC are referred to herein as the "IBC Shareholders"

                                 R E C I T A L S

         WHEREAS, IBC owns 307,203 shares of capital stock of Colonial Banking
Company ("CB").

         WHEREAS, VRB and CB are entering into a letter of intent (the "Letter
of Intent") of even date herewith, providing for the merger of VRB and CB (the
"Merger");

         WHEREAS, the parties to the Merger intend to enter into a definitive
agreement to consummate the Merger (the "Merger Agreement") within 90 days of
the date hereof, subject to completion of due diligence reviews;

         WHEREAS, under the Letter of Intent, a condition to the obligation of
VRB to close the Merger will be the acquisition by VRB of all of the outstanding
capital stock of IBC;

         WHEREAS, the IBC Shareholders approve in principle the proposal by VRB
to merge with CB, and desire to support and assist in completion of the
transaction by granting an option to VRB to acquire all shares of IBC capital
stock owned by each of the IBC Shareholders;

                                    AGREEMENT

         NOW THEREFORE, in consideration of the execution by VRB of the Letter
of Intent, the IBC Shareholders hereby agree as follows:

1.       Grant of Option. Each of the IBC Shareholders hereby irrevocably
grants to VRB the option (the "Option") to acquire the number of shares of IBC
capital stock set forth opposite his or her name below, at a price per share
equal to that amount calculated by multiplying the total number of shares of CB
capital stock held of record by IBC by $41.00, subtracting therefrom liabilities
of IBC, if any, and dividing the resulting figure by the total number of shares
of IBC capital stock outstanding as of the date of the exercise of this Option.

2.       Exercise of Option. VRB shall have the right to exercise the Option
at any time until March 31, 1998. Exercise shall be by written notice delivered
to the IBC Shareholders. Payment for the shares of stock subject to the Option
shall be made within 10 business days following exercise of the Option by
delivery of cashier's check or wire transfer, at the election of each IBC
Shareholder.

3.       Obligation of VRB to Exercise Option. Unless and until the Merger
Agreement is executed, VRB shall be under no obligation to exercise the Option.
Upon execution of the Merger Agreement, VRB will have the obligation to exercise
the Option and purchase the shares of IBC capital stock, subject to satisfaction
or waiver (except where required by law) of all conditions of closing the Merger
as set forth in the Merger Agreement and immediately before the closing of the
Merger.
<PAGE>   2
4.       Representations, Warranties and Covenants of IBC Shareholders. Each
of the undersigned IBC Shareholders represents, warrants and covenants to VRB as
follows:

         a. The number of shares of CB outstanding as of the date hereof is
         379,001. There are outstanding options to acquire 47,599 shares of CB
         weighted average exercise price of $10.61 per share. There are no other
         options, warrants or other rights to acquire shares of CB capital
         stock, and CB is not a party to any contract, agreement or other
         obligation to issue additional shares of capital stock. Prior to
         exercise or termination of this Stock Option Agreement, CB will not
         issue any shares of capital stock, nor any options, warrants or other
         rights to acquire shares of CB stock, nor declare or pay any dividends
         on its capital stock other than dividends as required by the terms of
         its preferred stock.

         b. The number of shares of IBC outstanding as of the date hereof is
         28,266.47. There are no outstanding options, warrants or other rights
         to acquire shares of IBC capital stock, other than options (the "IBC
         Options") held by Rollie Hutton and William Cundiff (the "IBC Option
         Holders") for each to purchase 500 shares of IBC capital stock at an
         exercise price of $100 per share. IBC is not a party to any other
         contract, agreement or other obligation to issue additional shares of
         capital stock. Prior to exercise or termination of this Stock Option
         Agreement, IBC will not issue any shares of capital stock, other than
         upon the exercise of the IBC Options held by the IBC Option Holders nor
         any options, warrants or other rights to acquire shares of IBC stock.
         If elected by the IBC Option Holders, the IBC Shareholders will cause
         IBC to cancel the IBC Options in consideration of the agreement of IBC
         to pay to the IBC Option Holders the difference between the
         consideration the IBC Option Holders would receive at the closing of
         the exercise of this Option and the exercise price of the IBC Options
         (the "Cancellation Consideration"). If the IBC Option Holders elect to
         cancel the IBC Options, the Cancellation Consideration shall be a
         liability of IBC at the closing of the exercise of this Option and
         shall be paid immediately following that closing. If, on the other
         hand, the IBC Option Holders elect to exercise their IBC Options prior
         to the closing of the exercise of this Option, the amount of
         consideration paid to acquire IBC shares in exercise of the this Option
         shall be additional consideration to be paid to the IBC shareholders
         upon the closing of the exercise of this Option. The terms of the IBC
         Options shall not be modified except as expressly permitted hereby
         prior to the termination of this Option.

         c. IBC's assets consist solely of 307,203 shares of CB capital stock,
         and any cash paid by the IBC Option Holders to exercise their options
         to purchase IBC shares, and at the closing of the exercise of this
         Option, IBC will have no outstanding liabilities or obligations to
         which it is subject, other than the obligation to pay the Cancellation
         Consideration if the IBC Option Holders so elect, and there is no basis
         for any person to assert any liability on the part of IBC for any
         reason whatsoever;

         d. The IBC Shareholders identified below are the only shareholders of
         IBC, and there are no other persons holding or controlling any
         securities of IBC which are convertible into equity securities of IBC.
         The number of shares set forth opposite each IBC Shareholder's name
         below represents all shares of IBC capital stock beneficially owned by
         such shareholder, and each such shareholder holds title to such shares
         free and clear of any lien or other encumbrance thereon.

         e. Each IBC Shareholder has all the necessary legal authority to enter
         into this Stock Option Agreement and to sell his or her shares of IBC
         capital stock that are subject hereof.

         f. Until closing of the merger of CB and VRB as contemplated by the
         Letter of Intent, neither IBC nor any of its directors, officers,
         employees, shareholders or agents will solicit or entertain an offer by
         any other person to enter into any contract or agreement which, if
         consummated, would
<PAGE>   3
         result in a majority of the outstanding voting stock of CB being
         acquired by, or CB merged or consolidated with, any other entity, or
         the sale of substantially all of the assets of CB.

         g. The representations and warranties under this section shall survive
         the closing of the exercise of this Option and the closing of the
         Merger.

5.       Termination. This Stock Option Agreement shall terminate on the earlier
         of any of the following:

         a. Upon exercise by VRB;

         b. 90 days following the date of the Letter of Intent, if no Merger
         Agreement has been executed, unless at such time, (I) VRB advises IBC
         Shareholders of its intent to acquire the IBC shares notwithstanding
         the absence of an executed Merger Agreement, (ii) offers to purchase
         all of the outstanding CB stock held by CB shareholders other than IBC
         for cash consideration of $43.36 per share, and (iii) VRB or VRB
         Bancorp shall have filed an application to the Board of Governors of
         the Federal Reserve System for prior approval to acquire the
         outstanding shares of IBC capital stock as provided in this Option;

         c. in the absence of a Merger Agreement, the later of January 1, 1998,
         or 10 days following receipt of all necessary and applicable regulatory
         approvals for VRB to exercise this Option;

         d. March 31, 1998; or

         e. Upon written release by VRB of the Option.

6.          Voting of Shares. The IBC Shareholders agree to support the Merger
and to cause IBC to vote its shares of CB stock in favor of the Merger at any
meeting of the shareholders of CB or action taken by consent of the shareholders
in lieu of such a meeting.

7.       General Provisions.

         a. Binding Effect. This Option shall be binding upon and inure to the
         benefit of the parties hereto and their heirs, executors,
         administrators, successors, and assigns.

         b. Notices. All notices to IBC Shareholders relating to this Stock
         Option Agreement shall be delivered to each IBC Shareholder at the
         respective address on the signature page of this Option or such other
         address as shall be specified in writing by the IBC Shareholder. All
         notices to the VRB shall be delivered at VRB's principal offices at 110
         Pine St., P.O. Box 1046, Rogue River, Oregon 97537.

         c. Governing Law and Interpretation. This Option shall be governed by
         the laws of the State of Oregon as to all matters, including but not
         limited to matters of validity, construction, effect and performance,
         without giving effect to rules of choice of law.

         d. Attorneys Fees. If any arbitration, suit or action is instituted in
         connection with any controversy arising out of this Option or the

         Colonial Bank represents and warrants to VRB as follows (except as
described in a Schedule of Exceptions heretofore delivered to VRB):

                  Organization, Existence, and Authority of Colonial Bank.
         Colonial Bank 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 conducted.
         Its activities do not require it to be qualified to do business in any
         other state.


                  Authorized and Outstanding Stock, Options, and Other Rights.
         The authorized capital stock of Colonial Bank consists of 2,000,000
         shares of common stock ($5.00 par value) of which 235,993 shares are
         outstanding and are validly issued, fully paid and nonassessable
         (except as provided by the Oregon Bank Act) and 160,857 shares of
         preferred stock ($10.50 par value) of which 143,008 shares are
         outstanding and are validly issued, fully paid and nonassessable
         (except as provided by the Oregon Bank Act). 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 Colonial Bank, or which enable or require
         Colonial Bank to acquire shares of its capital stock or other
         investment securities from any holder, are authorized, issued or
         outstanding except for options authorizing the holders thereof to
         acquire 47,599 Colonial Bank shares at a weighted average exercise
         price of $10.61.


                           Articles of Incorporation, Bylaws, Minutes. The
                  copies of the Articles of Incorporation, as amended, and the
                  Bylaws, as amended, of Colonial Bank delivered to VRB as
                  Schedule 2.3, are true, correct and complete copies of
                  existing Articles of Incorporation and Bylaws of Colonial Bank
                  as amended to date. Colonial Bank is not in material violation
                  of any provision of its Articles of Incorporation or Bylaws.
                  The minute books of Colonial Bank which have been or will be
                  made available to VRB for its review contain accurate and
                  complete minutes of all meetings and all consents evidencing
                  actions taken without a meeting by the Board of Directors (and
                  any committees thereof) and by its shareholders.


                  No Holding Company, Joint Venture, or Other Subsidiaries. No
         corporation or other entity is registered or, to the knowledge of
         Colonial Bank, 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 Colonial Bank except for IBC. Colonial Bank
         does not directly or indirectly own or control, either by power to
         control the investment or power to vote, any shares of capital stock of
         any other corporation or entity, other than 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. Colonial

         2.7, any financial statements furnished or to be furnished pursuant to

                  investigation against Colonial Bank, any such other person or
                  such Property as a result of any of the foregoing events.

                  delivered to VRB as Schedule 2.13 a list of contingent and
                  other liabilities not set forth in other schedules, together
                  with copies of documents evidencing those liabilities. Except
                  as set forth in the Colonial Bank Financial Reports or in

                  FDIC insured deposits, federal funds purchased and securities
                  sold under agreements to repurchase, and other obligations and
                  liabilities incurred in the ordinary course of business
                  arising out of transactions subsequent to the date of such
                  Financial Reports, Colonial Bank has 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 Colonial Bank.


                           No Adverse Changes. Since June 30, 1997, (a) there
                  has been no material adverse change in the business, assets,

                  distributions with respect to capital stock, have been
                  declared or paid by Colonial Bank except cash dividends as
                  required by the terms of Colonial Bank's preferred stock
                  outstanding, nor has Colonial Bank purchased or redeemed any
                  of its shares (other than purchases of stock options as
                  anticipated by Section 4.11 of the Plan of Merger); 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 Colonial Bank. As of the Effective Date,
                  Colonial Bank will have no obligations or liabilities of any
                  nature, whether absolute, accrued, contingent or otherwise, in
                  excess of $50,000 individually, or $100,000 in the aggregate,
                  other than:


                                       9
<PAGE>   11
         Obligations and liabilities disclosed in call reports as of June 30,
         1997 or otherwise disclosed to VRB pursuant to this Plan of Merger;

         Obligations and liabilities incurred in, or as a result of, the normal
         and ordinary course of business, consistent with past practices, which

         business, assets, earnings, operation or condition (financial or
         otherwise) of Colonial Bank; and

         Obligations and liabilities incurred otherwise than in or as a result
         of the normal and ordinary course of business consistent with past
         practices, provided VRB shall have consented thereto pursuant to
         Section 4.1 hereof.

above.

                           Regulatory Approvals Required. The nature of the
                  business and operations of Colonial Bank 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 Colonial Bank to perform its obligations under
                  this Plan, or to prevent the termination of any material
                  right, privilege, license or agreement of Colonial Bank, or
                  any material loss or disadvantage to its business, upon
                  consummation of the Plan of Merger, except for:


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

                           Corporate and Shareholder Approval of Plan, Binding
                  Obligations. Colonial Bank has all requisite corporate power
                  to execute, deliver and perform its obligations under this
                  Plan. The execution, delivery and performance of this Plan,
                  and the transactions contemplated thereby, have been duly
                  authorized by the Board of Directors of Colonial Bank. No
                  other corporate action on the part of Colonial Bank other than
                  shareholder approval is required to authorize the Plan of
                  Merger or the consummation of the transactions contemplated
                  thereby. This Plan has been duly executed and delivered by
                  Colonial Bank and constitutes the legal, valid and binding
                  obligation of Colonial Bank enforceable in accordance with its
                  terms.

                  with the governmental approvals described in Section 2.15,
                  neither the execution, delivery and performance of the Plan of
                  Merger by Colonial Bank, 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 its Articles of Incorporation or
                  Bylaws, or 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 it is a
                  party or by which it is bound, or will result in the
                  declaration or imposition of any lien, charge or encumbrance
                  upon any of the assets of Colonial Bank which are material to
                  their business.

                  adverse effect on Colonial Bank, (i) Colonial Bank, as a
                  member of the IBC consolidated group, has filed all federal,

                  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 Colonial Bank does not know of any pending or threatened
                  audit or investigation of Colonial Bank with respect to any
                  tax liabilities. There are currently no agreements in effect
                  to either extend the period of limitations for assessment or
                  collection of any tax. Colonial Bank has delivered to VRB as

                  Bank has delivered to VRB as Schedule 2.19 a list setting
                  forth all real property owned by Colonial Bank as present,
                  former or future bank premises and all real property currently

                  which have also been delivered to VRB as part of Schedule
                  2.19, are valid and effective in accordance with their
                  respective terms and there is not under any such lease any

                  default by Colonial Bank nor has there occurred any event
                  which, with the giving of notice, lapse of time, or otherwise,
                  would constitute an event of default. The real and personal
                  property leased by Colonial Bank is free of any adverse claims
                  known to Colonial Bank. Except as noted on Schedule 2.19, all
                  buildings and structures on the real property, the equipment
                  located thereon, and the real and personal property leased by
                  Colonial Bank, are in all material respects in good operating
                  condition and repair and conform in all material respects to
                  all applicable laws, ordinances and regulations. Colonial Bank
                  has good and marketable title to all of its real and personal
                  property, subject to no mortgages, pledges, encumbrances,
                  liens or charges of any kind, except liens for taxes not
                  delinquent and except as shown in Schedule 2.19 delivered to
                  VRB. Colonial Bank owns or leases all property on which its
                  continued business operations are materially dependent.


                           Insurance. Colonial Bank has provided to VRB as
                  Schedule 2.20 copies of all insurance policies currently in
                  force with respect to Colonial Bank's business and real and
                  personal property, and it will maintain all existing insurance
                  through the Effective Date. Colonial Bank is in compliance in
                  all material respects with all existing insurance policies and
                  has not failed to give timely notice or present any material
                  claim thereunder. Except as set forth in Schedule 2.20,
                  Colonial Bank has maintained such policies or comparable
                  coverage for each of the past six years.


                           Trademarks. Colonial Bank owns or licenses 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.


                           Contracts and Agreements. Colonial Bank has delivered
                  to VRB as Schedule 2.22, copies of all material outstanding
                  contracts, agreements, leases or understandings to which
                  Colonial Bank is a party or to which any of its properties are
                  subject, except those referred to in schedules furnished
                  pursuant to other sections of this Plan, and except for any
                  contracts or agreements entered into with Colonial Bank
                  customers in the ordinary course of business. Such documents
                  include, without limitation, all agreements, contracts, leases
                  or understandings with officers and directors of Colonial Bank
                  or VRB, all of which are related to, and have been entered
                  into in the ordinary course of, Colonial Bank's banking
                  business. Colonial Bank is not in material default or breach,
                  nor has there occurred any event which with notice or lapse of
                  time would constitute a material breach or default by Colonial
                  Bank, under any contract, agreement, instrument, lease or

                  reflected in Colonial Bank's regular delinquent loan reports
                  which have been and will be made available to VRB, Colonial
                  Bank does not know of any default by any other party thereto
                  and, no contract, agreement, lease or undertaking referred to
                  in Schedule 2.22, will be modified or changed prior to the
                  Effective Date without the prior written consent of VRB which

                  in effect. No waiver or indulgence has been granted by any of
                  the landlords under any such leases.

plan year in which the Effective Date occurs are set forth on Schedule 2.23.
There are no other material liabilities of Colonial Bank that would be incurred

officers and directors of Colonial Bank, all persons having fiduciary or other
responsibilities or duties with respect to any Benefit Plan, are, and have since
inception been, in compliance in all material respects with, and each such
Benefit Plan is and has been operated in all material respects in accordance
with, its provisions and in compliance with the applicable laws, rules and
regulations governing such


                                       13
<PAGE>   15
Plan, including, without limitation, the rules and regulations promulgated by
the Department of Labor, the Pension Benefit Guaranty Corporation and the IRS
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(b) or 403(a) or other applicable provisions of the Code, and all other
applicable laws, rules and regulations; all necessary governmental approvals for
the Benefit Plans have been obtained; and a favorable determination as to the

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
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"). Other than as required by
COBRA, and amounts due Participants under each Pension Benefit Plan, Colonial
Bank has no obligation to furnish health, severance or other benefits under any

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.

Guaranty Corporation ("PBGC"). No material liability to the PBGC has been or
will be incurred by Colonial Bank or other trade or business under "common
control" with Colonial Bank (as determined under section 414(c) of the Code)
("Common Control Entity") on account of any termination of an employee pension
benefit plan subject to title IV of ERISA. Except as set forth in Schedule 2.23,
since September 1, 1974, no filing has been made by Colonial Bank (or any Common
Control Entity) 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 Colonial Bank (or any Common
Control Entity). Neither Colonial Bank nor any Common Control Entity has (i)

4208 or ERISA).

                  (i) Complete and correct copies of the following documents
have been furnished to VRB as Schedule 2.23:

                          (i) Each Benefit Plan and any related trust

                          (ii) The most recent summary plan descriptions of each

                  (j) Each Welfare Benefit Plan and each Pension Benefit Plan is
legally valid and binding and in full force and effect.

                           Employment Disputes. There is no labor strike,
                  dispute, slowdown or stoppage pending or, to the best
                  knowledge of Colonial Bank, threatened against Colonial Bank,
                  and Colonial Bank does not have any knowledge of any attempt
                  to organize any employees of Colonial Bank into a collective
                  bargaining unit. Consummation of the Plan 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 Colonial Bank to any of its employees except
                  as set forth in Schedule 2.23. Colonial Bank is not a party to
                  any agreement involving payments to any person or entity based
                  upon the profits, revenues or other financial performance of
                  Colonial Bank except as set forth on Schedule 2.23.


                           Reserve for Loan Losses. Colonial Bank's reserve for
                  loan losses, as established from time to time, is adequate as
                  determined by the standards applied to Colonial Bank by the
                  applicable bank regulatory agencies and pursuant to generally
                  accepted accounting principles. At the time of closing, the
                  percentage


                                       15
<PAGE>   17
                  of the reserve to total loans will not be less than such
                  percentage was at June 30, 1997.


                           Repurchase Agreement. Colonial Bank 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 agreements.


                           Shareholder List. The list of shareholders of
                  Colonial Bank dated June 6, 1997, provided to VRB as Schedule
                  2.27, is a true, correct and complete list of the names,
                  addresses and holdings of all record holders of Colonial Bank
                  Stock as of that date. Colonial Bank shall notify VRB of any
                  change known to Colonial Bank in such stock ownership of over
                  one percent (1%) through the Effective Date.


                           Proxy Statement. The proxy statement to be used by
                  Colonial Bank to solicit proxies from the holders of Colonial
                  Bank Stock at the meeting of shareholders held to consider and
                  vote upon this Plan of Merger, and the transactions
                  contemplated thereby (in its definitive form the "Proxy
                  Statement"), will fairly describe the transaction and Colonial
                  Bank, 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.
                  Colonial Bank will promptly advise VRB in writing if at any
                  time prior to the Effective Date Colonial Bank 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.


                           Interests of Directors and Others. Except as shown on
                  Schedule 2.29, no officer or director of Colonial Bank has any
                  material interest in any assets or property (whether real or
                  personal, tangible or intangible), of or used in the business
                  of Colonial Bank other than as an owner of outstanding
                  securities or deposit accounts of Colonial 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 by Colonial Bank.

                  Warranties. During the period between the date hereof and the
                  earlier of the Effective Date or the termination of this Plan,
                  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 Plan 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

                  expressly limited to a state of facts existing at a time prior
                  to the occurrence of such event). In the event of, and
                  promptly upon becoming aware of the occurrence of or the

                  cause or constitute such a breach or inaccuracy, VRB will give
                  detailed written notice thereof to Colonial Bank and will use
                  its best efforts to prevent or promptly remedy such breach or

                           Updating Schedules. During the period between the
                  date hereof and the earlier of the Effective Date or the
                  termination of this Plan, VRB will, from time to time and as
                  appropriate to ensure that the schedules provided to Colonial
                  Bank remain at all times accurate and complete, to and
                  including the Effective Date, promptly supplement the

                  otherwise accomplish this Plan of Merger.

Colonial Bank employee benefits, including but not limited to pension plans,
thrift plans, management incentive plans, group life plans, accidental death and
dismemberment plans, vacation benefits, travel accident plans, medical and
hospitalization plans and long-term disability plans, on the same basis as
provided to similarly situated employees of VRB and without any exclusion or
reduction by reason of any pre-existing condition. From and after the Effective
Date, and until VRB has accomplished the actions contemplated by the preceding
sentence, employees who were employees of Colonial Bank immediately prior to the
Effective Time shall be provided with employee benefits under employee benefit
plans of Colonial Bank, or a combination of benefit plans of VRB and Colonial
Bank, as may be reasonably appropriate in order to accomplish an orderly
transition of benefits. From and after the Effective Date, employees who were
employees of Colonial Bank immediately prior to the Effective Date shall receive
full credit for all purposes under such plans for their length of service prior
to the Effective Date with Colonial Bank (and any predecessors thereto) except
for vesting purposes with respect to VRB's matching contributions for such
employees under its 401(k) plan; provided, however, previous Colonial Bank
employees completing two consecutive years of full time employment with VRB will
receive credit for prior service with Colonial Bank for the purpose of vesting
under VRB's 401(k) plan.

                  (b) VRB agrees to honor in accordance with their terms (i) all
Colonial Bank Employee Benefit Plans and (ii) all contracts, arrangements,
commitments, or understandings described in Schedule 2.23, and (iii) all
benefits vested thereunder as of the Effective Date, including without
limitation, accrued vacation pay. The provisions of this Section 5.5 are
intended to be for the benefit for, and enforceable by, each of the
beneficiaries of or parties to such plans, contracts, arrangements, commitments,
and understandings. Nothing herein, however, shall be deemed to require VRB to
continue such benefit plans.

         5.6 Indemnification; Directors' and Officers' Insurance. (a) In the
event of any threatened or actual claim, action, suit, proceeding, or
investigation, whether civil, criminal, or administrative, including without
limitation, any such claim, action, suit, proceeding, or investigation in which
any person who is now, or has been at any time prior to the date of this
Agreement, or who becomes prior to the Effective Date, a director, officer, or
employee of Colonial Bank (the "Indemnified Parties") is, or is threatened to
be, made a party based in whole or in part on, or arising in whole or in part
out of, or pertaining to (i) the fact that he is or was a director, officer, or
employee of Colonial Bank or any of its predecessors or (ii) this Agreement, the
Stock Option Agreement, or any of the transactions contemplated hereby or
thereby, whether in any case asserted or arising before or after the Effective
Date, the parties hereto agree to cooperate and use their best efforts to defend
against and respond thereto. It is understood and agreed that after the
Effective Date, VRB shall indemnify and hold harmless, as and to the fullest
extent permitted by law, each such Indemnified Party against any losses, claims,
damages,


                                       26
<PAGE>   28
liabilities, costs, expenses (including reasonable attorney's fees and expenses
in advance of the final disposition of any claim, suit, proceeding, or
investigation to each Indemnified Party to the fullest extent permitted by law
upon receipt of any undertaking required by applicable law), judgments, fines,
and amounts paid in settlement in connection with any such threatened or actual
claim, action, suit, proceeding, or investigation and in the event of any such
threatened or actual claim, action, suit, proceeding, or investigation (whether
asserted or arising before or after the Effective Date), the Indemnified Parties
may retain counsel reasonably satisfactory to them after consultation with VRB;
provided, however, that (1) VRB shall have the right to assume the defense
thereof and upon such assumption VRB shall not be liable to any Indemnified
Party for any legal expenses of other counsel or other expenses subsequently
incurred by any Indemnified Party in connection with the defense thereof, except
that if VRB elects not to assume such defense or counsel for the Indemnified
Parties reasonably advises the Indemnified Parties that there are issues which
raise conflicts of interest between VRB and the Indemnified Parties, the
Indemnified Parties may retain counsel reasonably satisfactory to them after
consultation with VRB, and VRB shall pay the reasonable fees and expenses of
such counsel for the Indemnified Parties, (2) VRB shall be obligated pursuant to
this paragraph to pay for only one firm of counsel for all Indemnified Parties,
unless an Indemnified Party shall have reasonably concluded, based on the advice
of counsel, that in order to be adequately represented, separate counsel is
necessary for such Indemnified Party, in which case, VRB shall be obligated to
pay for such separate counsel, (3) VRB shall not be liable for any settlement
effected without its prior written consent (which consent shall not be
unreasonably withheld), and (4) VRB shall have no obligation hereunder to any
Indemnified Party when and if a court of competent jurisdiction shall ultimately
determine, and such determination shall have become final and nonappealable,
that indemnification for such Indemnified Party in the manner contemplated
hereby is prohibited by applicable law. Any Indemnified Party wishing to claim
Indemnification under this Section 5.6, upon learning of any such claim, action,
suit, proceeding, or investigation, shall notify VRB thereof, provided that the
failure to so notify shall not affect the obligations of VRB under this Section
5.6 except to the extent such failure to so notify materially prejudices VRB.
VRB's obligations under this Section 5.6 continue in full force and effect for a
period of six years from the Effective Time; provided, however, that all rights
to indemnification in respect of any claim (a "Claim") asserted or made within
such period shall continue until the final disposition of such Claim and
provided further that VRB shall have the right of set-off against any payments
required to be made by VRB to an Indemnified Party pursuant to this Section
5.6(a) to the extent that such Indemnified Party shall have received the
indemnification to which such Indemnified Party is entitled from an insurer
under a directors' and officers' liability insurance policy maintained by
Colonial Bank. Excluded from the above indemnification are any claims made by
VRB pursuant to this Plan of Merger, claims (i) based upon a violation of
federal banking regulations including Regulation O, (ii) not permitted by ORS
707.746, or (iii) enumerated in ORS 707.110(5)(c)(A)-(D).

                  (b) VRB shall purchase or cause to be purchased one year of
extended discover coverage under Colonial Bank's current directors' and
officers' liability insurance policy maintained by Colonial Bank following the
Effective Date of the Plan of Merger.


                                       27
<PAGE>   29
                  (c) In the event VRB or any of its successors or assigns (i)
consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger,
or (ii) transfers or conveys all or substantially all of its properties and
assets to any person, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of VRB assume
the obligations set forth in this section.

                  (d) The provisions of this Section 5.6 are intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party and his or
her heirs and representatives.

                  of all regulatory waiting periods.

                  satisfactory to VRB and its counsel, to the effect that,

requested as of December 31, 1997 if all regulatory approvals have been received
and closing is anticipated early January 1998, Colonial Bank shall make a
provision sufficient to increase its loan loss reserves to 1.75% of its
outstanding loans. Any such provision shall not, however, be deemed a material

stock, surplus, and accumulated undivided profits including any current period
profit loss) as shown on its accounting records at the Effective Date after
adjustments necessary to reflect the application of generally accepted

reserve from the level required by Section 2.25, (ii) the amount and effect of

                  such information in accordance with Sections 9.3 and 9.4
                  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
                  party's respective counsel, accountants, tax advisors, and

                  maintain such information confidential in accordance with this
                  section and Sections 9.3 and 9.4 hereof, or to banking

                  hereto or waive compliance by the other parties hereto of any
                  of the covenants or conditions contained herein 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.

                  schedules and other documents or agreements referred to

                                    EXHIBIT A

                                DISSENTERS RIGHTS

         ORS 711.045

         (1) Any stockholder of an Oregon stock bank who dissented to a
transaction listed under section 280(1) of this 1997 Act and who desires to
receive the value in cash of those shares, shall make written demand upon the
Oregon stock bank or its successor and accompany the demand with the surrender
of the share certificates, properly indorsed within 30 days after the
stockholders' meeting at which a vote to approve such transaction involving an
Oregon stock bank was taken. Any stockholder failing to make written demand
within the 30-day period shall be bound by the terms of the proposed plan of
merger, plan of share exchange or acquisition transaction agreement.

         (2) Within 30 days after a transaction listed under section 280(1) of
this 1997 Act is effected, the Oregon stock bank or its successor shall give
written notice thereof to each dissenting stockholder who has made demand under
this section at the address of the stockholder on the stock record books of the
Oregon stock bank, and shall make a written offer to each such stockholder to
pay for the shares at a specified price in cash determined by the Oregon stock
bank or its successor to be the fair value of the shares as of the effective
date of the transaction. The notice and offer shall be accompanied by a
statement of condition of the Oregon stock bank, the shares of which the
dissenting stockholder held, as of the latest available date and not more than
four months prior to the consummation of the transaction, and a statement of
income of the Oregon stock bank for the period ending on the date of the
statement of condition.

         (3) Any stockholder who accepts the offer of the Oregon stock bank or
its successor within 30 days following the date on which notice of the offer was
mailed or delivered to dissenting stockholders shall be paid the price per share
offered, in cash, within 30 days following the date on which the stockholder
communicates acceptance in writing to the Oregon stock bank or its successor.
Upon payment, the dissenting stockholder shall cease to have any interest in the
shares previously held by the stockholder.

         (4) If, within 30 days after notice of the offer, one or more
dissenting stockholders do not accept the offer of the Oregon stock bank or its
successor or if no offer is made, then the value of the shares of the dissenting
stockholders who have not accepted the offer shall be ascertained, as of the
effective date of the transaction, by an independent, qualified appraiser chosen
by the Director of the Department of Consumer and Business Services. The
valuation determined by the appraiser shall govern and the appraiser's valuation
of such shares shall not be appealable except for one or more of the reasons set
forth in ORS 36.355(1). Any such appeal must be made within 30 days after the
date of the appraiser's valuation and is subject to ORS 183.415 to 183.500. The
Oregon stock bank or its successor shall pay the dissenting shareholders the
appraised value of the shares within 30 days after the date the appraiser sends
the Oregon stock bank or its successor written notice of the appraiser's
valuation.

         (5) The director shall assess the reasonable costs and expenses of the
appraisal proceeding equally to the Oregon stock bank or its successor and to
the dissenting shareholders, as a group, if the amount offered by the Oregon
stock bank or its successor is between 85 percent and 115 percent of the
appraised value of the shares. The director shall assess the reasonable costs
and expenses of the appraisal proceeding and the reasonable costs and expenses,
including attorney fees and costs, of the Oregon stock bank or its successor to
the dissenting stockholders, as a group, if the amount offered by the Oregon
stock bank or its successor is 115 percent or more of the appraised value of the
shares. The director shall assess the reasonable costs and expenses of the
appraisal proceeding and the reasonable costs and expenses, including


                                       -1-
<PAGE>   44
attorney fees and costs, of the dissenting shareholders, as a group, to the
Oregon stock bank or its successor if the amount offered by the Oregon stock
bank or its successor is 85 percent or less of the appraised value of the
shares. The director's decision regarding assessment of fees and costs may be
appealed as provided in ORS 183.415 to 183.500.

         (6) Amounts required to be paid by the Oregon stock bank or its
successors, or the dissenting shareholders under this section shall be paid
within 30 days after the director's assessment of any fees or costs becomes
final or, if the director's decision is appealed, within 30 days after a final
determination of such fees and costs is made.

         (7) The director may require, as a condition of approving a transaction
listed in section 280(1) of this 1997 Act, the replacement of all or a portion
of the stockholders' equity of an Oregon stock bank expended in payment to
dissenting stockholders under this section.

         (8) A stockholder may not receive the fair value of the stockholder's
shares under this section:

                  (a) If the plan of merger provides that all stockholders of
the resulting insured stock institution receive common stock of a holding
company pursuant to a merger with an interim Oregon stock bank chartered under
ORS 707.025, and the stockholder's Oregon stock bank and the interim Oregon
stock bank are the only parties to the merger; or

                  (b) If the shares held by the dissenting stockholder
immediately before the effective date of a transaction listed in section 280(1)
of this 1997 Act are listed on any national securities exchange or are included
on the list of over-the-counter margin stocks issued by the Board of Governors
of the Federal Reserve System.

1997 Or. Laws Ch.  ; Sections 280 - 282.

        Section 280

         (1) A stockholder of an Oregon stock bank may dissent from the
following:

                  (a) A plan of merger pursuant to which the Oregon stock bank
is not the resulting insured institution;

                  (b) A plan of merger pursuant to which the Oregon stock bank
is the resulting insured stock institution and the number of its voting shares
outstanding immediately after the merger, plus the number of shares issuable as
a result of the merger, either by the conversion of securities issued pursuant
to the merger or the exercise of rights and warrants issued pursuant to the
merger, will exceed by more than 20 percent the total number of voting shares of
the resulting insured stock institution outstanding immediately before the
merger;

                  (c) A plan of share exchange pursuant to which the Oregon
stock bank in which the stockholder owns shares is acquired; and

                  (d) An acquisition transaction requiring such stockholder's
approval pursuant to section 297(5) of this 1997 Act.


                                       -2-
<PAGE>   45
         (2) To perfect a stockholder's right to dissent to a transaction
described in subsection (1) of this section, the stockholder must send or
deliver a notice of dissent to the Oregon stock bank prior to or at the meeting
of the stockholders at which the transaction is submitted to a vote, or the
stockholder must vote against such transaction.

         (3) A stockholder shall not dissent as to less than all the shares
registered in the name of the stockholder, except a stockholder holding, as a
fiduciary or nominee, shares registered in the stockholder's name for the
benefit of more than one beneficiary, may dissent as to less than all of the
shares registered in the fiduciary or nominee's name if any dissent as to the
shares held for a beneficiary is made as to all the shares held by the fiduciary
for that beneficiary or nominee. The fiduciary's rights shall be determined as
if the shares to which the fiduciary has dissented and the other shares are
registered in the names of different stockholders.

         Section 281.

         (1) A dissenting stockholder making a demand under ORS 711.045 may
withdraw the demand if:

                  (a) The Oregon stock bank or its successor consents to the
withdrawal; or

                  (b) The dissenting stockholder pays such stockholder's pro
rata share of the appraisal costs and the Oregon stock bank's reasonable costs
and expenses, including attorney fees and costs.

         (2) When a dissenting stockholder withdraws the demand under subsection
(1) of this section, the stockholder's status as a stockholder shall be
restored, without prejudice to any corporate proceedings taking place in the
interim.

         Section 282.

         If a merger, conversion or acquisition of an Oregon bank involves a
trust company, the Director of the Department of Consumer and Business Services
shall not approve the merger, conversion, or acquisition until satisfied that
adequate provision has been made for successor fiduciaries.
