    Item 5: Other Events

    On July 25, 1994, Westamerica Bancorporation (the "Company")
    and PV Financial, parent company of Pacific Valley National
    Bank, issued a news release announcing the signing of a
    Definitive Agreement (the "Agreement") under which all of the
    outstanding shares of PV Financial Common Stock will be
    exchanged for shares of the Company's Common Stock pursuant to a
    tax-free exchange. The Agreement, which has been approved by the










    Board of Directors of both companies, is subject to approval by
    PV Financial shareholders, clearance by regulatory authorities
    and other terms and conditions customary for transactions of
    this type.

    The Agreement provides that holders of each share of PV
    Financial Common Stock will be entitled to receive, on a
    tax-free basis, .545 of a share of the Company's Common Stock.
    Pursuant to the Agreement, the exchange ratio is subject to
    adjustment if the Company's average share price on the NASDAQ
    prior to the effective date of the merger exceeds $32.06 and is
    subject to renegotiation if the Company's average share price
    prior to the merger is below $28.43. Although no formal
    timetable for the merger has been set, it is estimated the
    closing will occur in early 1995.

    Following the execution of the Agreement, PV Financial, as a
    condition to, and in consideration for entering into, the
    Agreement, granted the Company an option to purchase up to
    433,142 shares of Common Stock (the "Option Shares") at an
    exercise price of $12.25 per share (the "Stock Option").

    The Option Shares, if issued, pursuant to the Stock Option
    Agreement, would represent approximately 19.9% of the issued and
    outstanding shares (excluding treasury shares) of PV Financial's
    Common Stock without giving effect to the issuance of any shares
    pursuant to an exercise of the Stock Option and in no event will
    the number of Option Shares exceed 19.9% of PV Financial's
    issued and outstanding Common Stock.

    The number of shares of PV Financial's Common Stock subject to
    the Stock Option will be increased to the extent that PV
    Financial issues additional shares of Common Stock (otherwise
    than pursuant to an exercise of the Stock Option) such that the
    number of Option Shares will continue to equal 19.9% of the then
    issued and outstanding shares of PV Financial's Common Stock
    without giving effect to the issuance of shares pursuant to an
    exercise of the Stock Option. In the event PV Financial issues
    or agrees to issue any shares of Common Stock (other than as
    permitted under the Agreement) at a price less than $12.25 per
    share (or lower than an adjusted price per share), the exercise
    price will be equal to such lesser price. The number of shares
    of PV Financial's Common Stock subject to the Stock Option, and
    the applicable exercise price per Option Share, also will be
    appropriately adjusted in the event of any stock dividend,
    split-up, merger, recapitalization, combination. subdivision,
    conversion, exchange of shares, or similar event relating to PV
    Financial.

    The Company may exercise the Stock Option, in whole or in part,
    subject to regulatory approval, at any time within 30 days
    (subject to extension as provided in the Stock Option Agreement)
    after both an "Initial Triggering Event" and a "Subsequent
    Triggering Event" occur prior to termination of the Stock Option.

    "Initial Triggering Event" is defined as the occurrence of any










    of the following events:

    (z) being referred to as an "Acquisition Transaction");

    Company's prior written consent, shall have authorized,

    right to acquire beneficial ownership of 10% or more of the
    outstanding shares of PV Financial Common Stock;

    (iv) any person or group (other than the Company or any
    subsidiary thereof) shall make a bona fide proposal to PV
    Financial or its shareholders by public announcement or written
    communication, that is or becomes the subject of public
    disclosure, to engage in an Acquisition Transaction;

    (v) a third party shall make a proposal to PV Financial or its
    shareholders to engage in an Acquisition Transaction, followed
    by PV Financial breaching any covenant or obligation contained
    in the Agreement, such breach entitling the Company to terminate
    the Agreement, and such breach not being cured prior to the date
    that the Company sends notice of its exercise of the Stock
    Option to PV Financial; or

    (vi) any person or group (other than the Company or any
    subsidiary thereof), other than in connection with a transaction
