REDDING BANCORP & SUBSIDIARIES
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements should be read in
conjunction with the financial statements and related notes contained in Redding
Bancorp's 1999 Annual Report to Shareholders. The statements include the
accounts of Redding Bancorp ("the Company"), and its wholly owned subsidiaries,
Redding Bank of Commerce ("RBC") and Redding Service Corporation. All
significant inter-company balances and transactions have been eliminated. The
financial information contained in this report reflects all adjustments that in
the opinion of management are necessary for a fair presentation of the results
of the interim periods. All such adjustments are of a normal recurring nature.
The results of operations and cash flows for the three months ended March 31,
2000 are not necessarily indicative of the results that may be expected for the
year ending December 31, 2000.

For purposes of reporting cash flows, cash and cash equivalents include cash on
hand, amounts due from banks, federal funds sold and repurchase agreements.
Federal funds sold and repurchase agreements are generally for one day periods.

2. EARNINGS PER SHARE

Basic earnings per share excludes dilution and is computed by dividing net
income by the weighted-average number of common shares outstanding for the
period. Diluted earnings per share reflects the potential dilution that could
occur if securities or other contracts to issue common stock were exercised or
converted into common stock or resulted in the issuance of common stock that
then shared in the earnings of the entity. The following table displays the
computation of earnings per share for the three ended March 31, 2000 and 1999.

(Dollars in thousands, except earnings per share data)

6. NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and hedging activities. The statement

GENERAL

     The Company is a bank holding company with its principal offices in
Redding, California. The Company engages in a general commercial banking
business in Redding and the counties of El Dorado, Placer, Shasta, and
Sacramento, California. The Company considers Shasta County to be the Company's
major market area. The Company conducts its business through the Bank, its
principal subsidiary. The services offered by the Company include those
traditionally offered by commercial banks of similar size and character in
California, such as checking, interest-bearing checking ("NOW") and savings
accounts, money market deposit accounts, commercial, construction, real estate,
personal, home improvement, automobile and other installment and term loans,
travelers checks, safe deposit boxes, collection services, and telephone
transfers. The Company has had a loan production office in the Sacramento area
since 1988. On March 15, 2000, the Company filed applications with the Federal
Deposit Insurance Corporation and the California Department of Financial
Institutions to convert the Sacramento loan production office to a full service
banking facility. On March 29, 2000, the Company received notification from the
Federal Deposit Insurance Corporation approving the new facility effective April
10, 2000.

     The primary focus of the Company is to provide service to the business and
professional community of its major market area including Small Business
Administration ("SBA") loans, and payroll and accounting packages and billing
programs. The Company does not offer trust services or international banking
services and does not plan to do so in the near future.

     On November 12, 1999 President Clinton signed into law the
Gramm-Leach-Bliley Act, or the Financial Services Act of 1999 (the "FSA") which
became effective on March 11, 2000. The FSA repeals provisions of the
Glass-Steagall Act, which had prohibited commercial banks and securities firms
from affiliating with each other and engaging in each other's businesses. Thus,
many of the barriers prohibiting affiliations between commercial banks and
securities firms have been eliminated.

     The BHCA is also amended by the FSA, to allow new "financial holding
companies" ("FHC") to offer banking, insurance, securities and other financial
products to consumers. Specifically, the FSA amends section 4 of the BHCA in
order to provide for a framework for the engagement in new financial activities.
Bank holding companies ("BHC") may elect to become a financial holding company
if all its subsidiary depository institutions are well-capitalized and
well-managed. If these requirements are met, a BHC may file a certification to
that effect with the FRB and declare that it chooses to become a FHC. After the
certification and declaration is filed, the FHC may engage either de novo or
though an acquisition in any activity that has been determined by the FRB to be
financial in nature or incidental to such financial activity. On March 15, 2000
the Company filed the necessary certification and declarations to become a
financial holding company. On March 28, 2000 the Company received notification
from the Federal Reserve Board that the election to become a financial holding
company will be effective on April 22. 2000.

     The Company derives its income from two principal sources: (i) net interest
income, which is the difference between the interest income it receives on
interest-earning assets and the interest expense it pays on interest-bearing
liabilities, and (ii) fee income, which includes fees earned on deposit
services, income from SBA lending, electronic-based cash management services and
merchant credit card processing services. Management considers the business of
the Company to be divided into two segments: (i) commercial banking and (ii)
credit card services. Credit card services are limited to those revenues, net of
related data processing costs, associated with the Merchant Services Agreement
and the Bank's agreement to provide credit and debit card processing services
for merchants solicited by the Bank who accept credit and debit cards as
payments for goods and services.

     RESULTS OF OPERATIONS

     The Company reported earnings of $1,165,000, for the quarter ended March
31, 2000. The quarterly earnings represent a 29.6% increase over the $899,000
reported for the same period of 1999. Diluted earnings per share for the first
quarter of 2000 were $0.41, compared to $0.31 for the same period of 1999.

     Factors contributing to the increase in operating results include an
increase in the volume of earning assets, an increase in net interest rate
spread and margin, coupled with a decrease in other non-interest expense
representing the closing of the Chico loan production office, and a reduction in
professional legal expensES.

     NET INTEREST INCOME

     Net interest income is the primary source of income for the Bank. Net
interest income represents the excess of interest and fees earned on
interest-earning assets (loans, investments and Federal Funds sold) over the
interest paid on deposits and borrowed funds. Net interest margin is net
interest income expressed as a percentage of average earning assets.

     For the three months ended March 31, 2000, interest income increased
$616,000 (15.1%) over the same period in 1999. Interest expense on deposit
accounts and borrowings increased $327,000 (22.1%) over the same three-month
period in 1999. During this quarter, the Company obtained brokered deposits of
$4,700,000 due in March 2002, at a yield of 7.03% intended to stabilize
liquidity and assist in the development of the Roseville Banking Center. The
strategy is to replace the brokered deposits with core deposits developed at the
new location.

     The combined effect of the increase in volume of earning assets and
increase in yield on earning assets, coupled with increases in cost of funding
sources resulted in an increase of $289,000 (11.2%) in net interest income for
the three month period ended March 31, 2000 over the same period in 1999. Net
interest margin increased 25 basis points to 5.35% from 5.10% for the same
period a year ago. The increase is a result of the current rising interest rate
environment.

NONINTEREST INCOME

     The Company's noninterest income consists of processing fees for merchants
who accept credit card payments for goods and services, service charges on
deposit accounts, and other service fees. In April 1993, the Bank entered into
an agreement (the "Merchant Services Agreement") with Cardservice International,
Inc. ("CSI"), an independent sales organization ("ISO") and nonbank merchant
credit card processor, pursuant to which the Bank has agreed to provide credit
and debit card processing services for merchants solicited by CSI who accept
credit and debit cards as payment for goods and services. Pursuant to the
Merchant Services Agreement, the Bank acts as a clearing bank for CSI and
processes credit or debit card transactions into the Visa(R) or MasterCard(R)
system for presentment to the card issuer. As a result of the Merchant Services
Agreement, the Bank has acquired electronic credit and debit card processing
relationships with merchants in various industries on a nationwide basis. The
Merchant Services Agreement with CSI was renewed in 1997 for a period of four
years, which expires on April 1, 2001, and will automatically renew for
additional four-year periods unless terminated in advance of the renewal period
by CSI upon 90 days written notice or by the Bank upon 30 days prior written
notice. Although CSI has not terminated the Merchant Services Agreement, the
Company and CSI are renegotiating the terms of the Merchant Services Agreement
for the four-year period commencing April 1, 2001. If the Company and CSI are
unable to reach agreement with respect to the renewal terms of the Merchant
Services Agreement, the Company expects that CSI will terminate the Merchant
Services Agreement. Termination of the Merchant Services Agreement would result
in a significant decline in revenues from merchant credit card processing and
have a material adverse affect on the Company results of operations.

     For the three months ended March 31, 2000, noninterest income decreased a
modest $5,000 over the same period in 1999. Credit card processing income
increased $55,000 (13.3%) while service charge income declined $20,000 (27.4%)
over the same period 1999.


                                       11
<PAGE>   12
Historically the Company's service charges on deposit accounts have lagged peer
levels for similar services. This is consistent with the Company's philosophy of
allowing customers to pay for services with compensating balances and the
emphasis on certificates of deposit as a significant funding source.
Contributing to the decrease in noninterest income are losses on sales of
investment securities sold for liquidity purposes. Management determined the
sales of investment securities to be more cost effective than increasing
borrowings.

The following table sets forth a summary of noninterest income for the periods
indicated.

NONINTEREST EXPENSE

     Noninterest expenses consist of salaries and related employee benefits,
occupancy and equipment expenses, data processing fees, professional fees,
directors' fees and other operating expenses.

     For the three months ended March 31, 2000, noninterest expense decreased
$116,000 over the same period in 1999. Salaries and benefits decreased $63,000
(6.5%) indicative of the closure of the Chico loan production office, increases
in the deferral portion of loan costs used to offset salaries, and a reduction
in the accrual for profit sharing.

     The following table sets forth a summary of noninterest expense for the
periods indicated.

INCOME TAXES

     The Company's provision for income taxes includes both federal and state
income taxes and reflects the application of federal and state statutory rates
to the Company's net income before taxes. The principal difference between
statutory tax rates and the Company's effective tax rate is the benefit derived
from investing in tax-exempt securities. Increases and decreases in the
provision for taxes reflect changes in the Company's net income before tax.

The following table reflects the Company's tax provision and the related
effective tax rate for the periods indicated.

ASSET QUALITY

     The Company concentrates its lending activities primarily within Shasta
County, California, and the location of the Bank's two full service branches.
The Company also makes loans to borrowers in El Dorado, Placer, and Sacramento
counties through its Roseville loan production office.

     The Company manages its credit risk through diversification of its loan
portfolio and the application of underwriting policies and procedures and credit
monitoring practices. Although the Company has a diversified loan portfolio, a
significant portion of its borrowers' ability to repay the loans is dependent
upon the professional services and residential real estate development industry
sectors. Generally, the loans are secured by real estate or other assets and are
expected to be repaid from the cash flows of the borrower or proceeds from the
sale of collateral.

     The following table sets forth the amounts of loans outstanding by category
as of the dates indicated:

     The Company's practice is to place an asset on nonaccrual status when one
of the following events occurs: (i) any installment of principal or interest is
90 days or more past due (unless in management's opinion the loan is well
secured and in the process of collection). (ii) Management determines the
ultimate collection of principal or interest to be unlikely or (iii) the terms
of the loan have been renegotiated due to a serious weakening of the borrower's
financial condition. Nonperforming loans are loans that are on nonaccrual, are
90 days past due and still accruing or have been restructured.

     Net portfolio loans increased $4,047,000 or 2.4% at March 31, 2000 over
$169.8 million at December 31, 1999. The portfolio mix remains stable with the
mix at December 31, 1999, with commercial and financial loans of approximately
30%, real estate construction of 22% and commercial real estate at 48%.

     Impaired loans are loans for which it is probable that the Bank will not be
able to collect all amounts due. The Bank had outstanding balances of $369,176
and $394,176 in impaired loans that had impairment allowances of $295,341 and
$315,341 as of March 31, 2000 and December 31, 1999, respectively.

ALLOWANCE FOR LOAN AND LEASE LOSSES (ALLL)

     The Company makes provisions to the ALLL on a regular basis through charges
to operations that are reflected in the Company's statements of income as a
provision for loan losses. When a loan is deemed uncollectible, it is charged
against the allowance. Any recoveries of previously charged-off loans are
credited back to the allowance. There is no precise method of predicting
specific losses or amounts that ultimately may be charged-off on particular
categories of the loan portfolio.

     Similarly, the adequacy of the ALLL and the level of the related provision
for possible loan losses is determined on a judgment basis by management based
on consideration of (i) economic conditions, (ii) borrowers' financial
condition, (iii) loan impairment, (iv) evaluation of industry trends, (v)
industry and other concentrations, (vi) loans which are contractually current as
to payment terms but demonstrate a higher degree of risk as identified by
management, (vii) continuing evaluation of the performing loan portfolio, (viii)
monthly review and evaluation of problem loans identified as having loss
potential, (ix) quarterly review by the Board of Directors, (x) off balance
sheet risks and (xi) assessments by regulators and other third parties.
Management and the Board of Directors evaluate the allowance and determine its
desired level considering objective and subjective measures, such as knowledge
of the borrowers' business, valuation of collateral, the determination of
impaired loans and exposure to potential losses.

     The ALLL is a general reserve available against the total loan portfolio
and off balance sheet credit exposure. It is maintained without any
interallocation to the categories of the loan portfolio, and the entire
allowance is available to cover loan losses. While management uses available
information to recognize losses on loans, future additions to the allowance may
be necessary based on changes in economic conditions. In addition, various
regulatory agencies, as an integral part of their examination process,
periodically review the Bank's ALLL. Such agencies may require the Bank to
provide additions to the allowance based on their judgment of information
available to them at the time of their examination. There is uncertainty
concerning future economic trends. Accordingly, it is not possible to predict
the effect future economic trends may have on the level of the provision for
possible loan losses in future periods.

     The ALLL should not be interpreted as an indication that charge-offs in
future periods will occur in the stated amounts or proportions.

     The adequacy of the ALLL is calculated upon three components. First is the
dollar weighted risk rating of the loan portfolio, including all outstanding
loans and leases, off balance sheet items, and commitments to lend. Every
extension of credit has assigned a risk rating based upon a comprehensive
definition intended to measure the inherent risk of lending money. Each rating
has an assigned a risk factor expressed as a reserve percentage. Central to this
assigned risk (reserve) factor is the five-year historical loss record of the
bank.

     Secondly, established specific reserves are available for individual loans
currently on management watch and high-grade loan lists. These are the estimated
potential losses associated with specific borrowers based upon the collateral
and event(s) causing the risk rating.

     The third component is unallocated. This reserve is for qualitative factors
that may effect the portfolio as a whole, such as those factors described above.

     Management believes the assigned risk grades and our methods for managing
changes are satisfactory. Management believes the loan portfolio performance has
improved as reflected by the stable and low delinquency ratio. Watch list and
high-grade loans have increased somewhat o ver the past year, primarily due to a
greater acceptance to move more susceptible although performing accounts to
attention. This minimal increase does not suggest a trend.

INVESTMENT PORTFOLIO

     Total investment securities decreased $5,534,000 in the first three months
of 2000 or 17.2%. The decrease represents maturities of $1,030,000 and sales of
$4,435,000. Proceeds from the sales of investment securities were used to fund
loan commitments.

LIQUIDITY

     With respect to assets, liquidity is provided by cash and money market
investments such as interest-bearing time deposits, federal-funds sold,
investment securities available-for-sale and principal and interest payments on
loans. With respect to liabilities, the Company's core deposits, shareholders'
equity and the ability of the Bank to borrow funds and to generate deposits,
provide asset funding.

     Because estimates of the liquidity need of the Bank may vary from actual
needs, the Bank maintains a substantial amount of liquid assets to absorb short
term increases in loans or reductions in deposits.

     The Company's liquid assets (cash and due from banks, federal funds sold
and available-for-sale investment securities) totaled $49,260,000, or 20.4% of
total assets, at March 31, 2000 compared to $44,539,000 or 19.1% of total assets
at December 31, 1999.

     During the current period, the Company obtained brokered deposits totaling
$4,700,000 due in March 2002, at a discounted yield of 7.03%. The purpose of the
deposits is to provide a stable liquidity source to assist in the development of
the Roseville Banking Center. The development of core deposits will replace this
borrowing at maturity.

     Overall capital adequacy is monitored on a day-to-day basis by the
Company's management and reported to the Company's Board of Directors on a
monthly basis. The Bank's regulators measure capital adequacy by using a
risk-based capital framework and by monitoring compliance with minimum leverage
ratio guidelines. Under the risk-based capital standard, assets reported on the
Company's balance sheet and certain off-balance sheet items are assigned to risk
categories, each of which is assigned a risk weight.

This standard characterizes an institution's capital as being "Tier 1" capital
(defined as principally comprising shareholders' equity) and "Tier 2" capital
(defined as principally comprising the qualifying portion of the ALLL).

The minimum ratio of total risk-based capital to risk-adjusted assets, including
certain off-balance sheet items, is 8%. At least one-half (4%) of the total
risk-based capital (Tier 1) is to be comprised of common equity; the balance may
consist of debt securities and a limited portion of the ALLL.

     The following table sets forth the Company's capital ratio as of the dates
indicated.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     The Company's primary component of market risk is interest rate volatility.
Fluctuation in interest rates will ultimately impact both the level of interest
income and interest expense recorded on a large portion of the Company's assets
and liabilities, and the fair market value of interest earning assets and
interest-bearing liabilities, other than those which possess a short term to
maturity. Because the Company's interest-bearing liabilities and
interest-earning assets are with the Bank, the Company's interest rate risk
exposure is in connection with the operations of the Bank. Consequently, all
significant interest rate risk management procedures are performed at the Bank
level.

     Based upon the nature of its operations, the Bank is not subject to foreign
currency exchange or commodity price risk. The fundamental objective of the
Company's management of its assets and liabilities is to enhance the economic
value of the Company while maintaining adequate liquidity and an exposure to
interest rate risk deemed acceptable by the Company's management.

     The Company manages its exposure to interest rate risk through adherence to
maturity, pricing and asset mix policies and procedures designed to mitigate the
impact of changes in market interest rates. The Bank's profitability is
dependent to a large extent upon its net interest income, which is the
difference between its interest income on interest-earning assets, such as loans
and securities, and its interest expense on interest-bearing liabilities, such
as deposits and borrowings.

     The formal policies and practices adopted by the Bank to monitor and manage
interest rate risk exposure measure risk in two ways: (i) repricing
opportunities for earning assets and interest-bearing liabilities and (ii)
changes in net interest income for declining interest rate shocks of 100 and 200
basis points.

     Because of the Bank's capital position and noninterest-bearing demand
deposit accounts, the Bank is asset sensitive. As a result, management
anticipates that, in a declining interest rate environment, the Company's net
interest income and margin would be expected to decline, and, in an increasing
interest rate environment, the Company's net interest income and margin would be
expected to increase. However, no assurance can be given that under such
circumstances the Company would experience the described relationships to
declining or increasing interest rates.

     Because the Bank is asset sensitive, the Company is adversely affected by
declining rates rather than rising rates. This effect is partially offset in the
short-term by the fact that the Company is liability sensitive through the
cumulative GAP period of one year or less. During a period of declining rates,
such liabilities may be repriced to provide a short-term advantage to the
Company; however, this benefit may not be sustainable over the long-term.

     To estimate the effect of interest rate shocks on the Company's net
interest income, management uses a model to prepare an analysis of interest rate
risk. Such analysis calculates the change in net interest income given a change
in the federal funds rate of 100 basis points up or down. All changes are
measured in dollars and are compared to projected net interest income. At March
31, 2000, the estimated annualized reduction in net interest income attributable
to a 100 and 200 basis point decline in the federal funds rate was $441,500 and
$883,000, respectively. A similar and opposite result attributable to a 100
basis point increase in the federal funds rate. At December 31, 1999, the
estimated annualized reduction in net interest income attributable to a 100 and
200 basis point decline in the federal funds rate was $359,000 and $718,000,
respectively, with a similar and opposite result attributable to a 100 basis
point increase in the federal funds rate. Management does not believe that the
change from in the first quarter is significant or represents a known trend
toward more interest rate risk sensitivity in the Company's financial position.

     The model utilized by management to create the analysis described in the
preceding paragraph uses balance sheet simulation to estimate the impact of
changing rates on the annual net interest income of the Bank. The model
considers a number of factors, including (i) change in customer and management
behavior in response to the assumed rate shock, (ii) the ratio of the amount of
rate change for each interest-bearing asset or liability to assumed changes in
the federal funds rate based on local market conditions for loans and core
deposits and national market conditions for other assets and liabilities and
(iii) timing factors related to the lag between the rate shock and its effect on
other interest-bearing assets and liabilities. Actual results will differ when
actual customer and management behavior and ratios differ from the assumptions
utilized by management in its model. In addition, the model has limited
usefulness for the measurement of the effect on annual net interest income
resulting from rate changes other than 100 basis points. Management believes
that the short duration of its rate-sensitive assets and liabilities contributes
to its ability to reprice a significant amount of its rate-sensitive assets and
liabilities and mitigates the impact of rate changes more than 100 basis points.
The model's primary benefit to management is its assistance in evaluating the
impact that future strategies with respect to the Bank's mix and level of
rate-sensitive assets and liabilities will have on the Company's net interest
income.
