Foothill Independent Bank
Partners In Your Future 401(K) Profit Sharing Plan
Glendora, California

We have audited the accompanying statements of net assets available for benefits
of the Foothill Independent Bank Partners in Your Future 401 (K) Profit Sharing
Plan as of December 31, 1999 and 1998, and the related statements of changes in
net assets available for benefits for the years then ended. These financial
statements are the responsibility of the Plan'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
misstatements. 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 net assets available for benefits of the Foothill
Independent Bank Partners In Your Future 401 (K) Profit Sharing Plan at December
31, 1999 and 1998, and the changes in its net assets available for benefits for
the years then ended in conformity with generally accepted accounting
principles.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental Schedule of Assets Held
for Investment Purposes is presented for the purpose of additional analysis and
is not a required part of the basic financial statements, but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental schedule has been subjected to the auditing procedures
applied in the audits of the basic financial statements and, in our opinion, is
fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

                           DECEMBER 31, 1999 AND 1998

NOTE #1 - DESCRIPTION OF PLAN

The following description of the Foothill Independent Bank Partners in Your
Future 401(K) Profit Sharing Plan ("the Plan") provides only general
information. Participants should refer to the Plan agreement for a more complete
description of the Plan's provisions.

A.  General

    The Plan is a defined contribution plan covering all full-time employees of
    Foothill Independent Bank (FIB). There is no age or service requirement. It
    is subject to the provisions of the Employee Retirement Income Security Act
    of 1974 (ERISA). FIB adopted the Plan effective January 1, 1994.

B.  Contributions

    Each year, FIB contributes to the Plan matching contributions equal to a
    discretionary percentage, to be determined by the Employer, of the
    participant's salary reductions. Participants may contribute up to 15% of
    their annual wages before bonuses and overtime, not to exceed a limit set by
    law. The limit for 1999 was $10,000. FIB's matching contribution is in the
    form of FIB stock.

C.  Participant Accounts

    Each participant's account is credited with the participant's contribution
    and allocation of (a) the FIB contributions, and (b) Plan earnings.
    Allocations are based on participant earnings or account balances, as
    defined. The benefit to which a participant is entitled is the benefit that
    can be provided from the participant's vested account.

D.  Vesting

    Participants are vested in FIB contributions according to the following
    schedule:


                    Year of
                    Service                                 Percentage
                    -------                                 ----------

                    1 Year                                      25%
                    2 Years                                     50%
                    3 Years                                    100%

    Employee contributions, deferrals and rollovers are immediately 100% vested.
    No vested benefit may be forfeited.

NOTE #1 - DESCRIPTION OF PLAN, Continued

E.  Payment of Benefits

    On termination of service, a participant may elect to receive a lump-sum
    amount equal to the value of the participant's vested interest in his or her
    account. Participants with vested balances greater than $3,500 may opt to
    leave the balance with the Plan.

F.  Loans to Participants

    Participants may apply for a loan of up to one-half total contributions. The
    loans are secured by the accounts of the participant. The loans are
    available to all participants and bear a reasonable rate of interest.

G.  Forfeited Accounts

    At December 31, 1999, forfeited non-vested accounts totaled $20,524. These
    accounts will be used to reduce future employer contributions.

NOTE #2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A.  Basis of Accounting

    The financial statements of the Plan are prepared using the accrual method
    of accounting.

B.  Estimates

    The preparation of financial statements in conformity with generally
    accepted accounting principles requires the plan administrator to make
    estimates and assumptions that affect certain reported amounts and
    disclosures. Accordingly, actual results may differ from those estimates.

C.  Valuation of Assets

    The Plan's investments are stated at fair value. Shares of registered
    investment companies are valued at quoted market prices which represent the
    net asset value of shares held by the Plan at year-end. The Company stock is
    valued at its quoted market price. Participant notes receivable are valued
    at cost which approximates fair value.

    Purchases and sales of securities are recorded on a trade-date basis.
    Interest income is recorded on the accrual basis. Dividends are recorded on
    the date received.

NOTE #2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, Continued

D.  Tax Status

    The Trust established by the Plan to hold the Plan's assets is qualified
    Internal Revenue Code Section 410(b). Accordingly, the Plan's net investment
    income is exempt from income taxes. The Plan has received a favorable tax
    determination letter from the Internal Revenue Service and the Plan sponsor
    believes that the Plan continues to qualify and operate as designed.

E.  Administration of Plan Assets

    Contributions made by FIB and its employees are held and managed by a
    Trustee, which invests the cash received, interest and dividends in
    accordance with participant's instructions. Distributions to participants
    are made by the Trustee. The Trustee also administers the payment of
    principal and interest on participant loans.

    Certain administrative functions are performed by officers or employees of
    FIB. No such officer or employee receives additional compensation from the
    Plan. The administrative and Trustee fees associated with the Plan are paid
    by FIB and not from the Plan assets.

NOTE #3 - INVESTMENTS

Investments are valued at fair value base upon quoted market prices at year-end.
At December 31, 1999, investments were made up of the following:


                                                                      Net
