                "Four. This Corporation is authorized to issue two (2) classes
        of shares of stock: one class of shares to be called "Common Stock"; the
        second class of shares to be called "Serial Preferred Stock." The total
        number of shares of stock which the Corporation shall have authority to
        issue is Forty-five million (45,000,000), of which Twenty-Five Million
        (25,000,000) shall be Common Stock and Twenty Million (20,000,000) shall
        be Serial Preferred Stock. At the time the amendment to this Article to
        read as herein set forth becomes effective, each outstanding share of
        capital stock of this Corporation shall be reclassified as one share of
        Common Stock of the Corporation.

        qualifications, limitations or restrictions thereof, of each class of

                        (a) Serial Preferred Stock.

                The Serial Preferred Stock may be issued from time to time in

        or alter the rights, preferences, privileges and restrictions granted to
        or imposed upon any wholly unissued series of preferred shares, and the
        number of shares constituting any such series and a designation thereof,
        or any of them; and to increase or decrease the number of shares of any
        series subsequent to the issue of shares of that series, but not below
        the number of such series then outstanding. In case the number of shares
        of any series shall be so decreased, the shares constituting such
        decrease shall resume the status which they had prior to the adoption of
        the resolution originally fixing the number of shares of such series.

                        (b) Common Stock

                (1) After the requirements with respect to preferential
        dividends upon all classes and series of stock entitled thereto shall
        have been paid or declared and set apart for payment and after the
        Corporation shall have complied with all requirements, if any, with
        respect to the setting aside of sums as a sinking fund or for a
        redemption account on any class of stock, then and not otherwise, the
        holders of Common Stock shall be entitled to receive, subject to the
        applicable provisions of the Corporations Code of the State of
        California, such dividends as may be declared from time to time by the
        Board of Directors.

        distributed to the holders of all classes and series of stock entitled
        thereto in the event of a voluntary or involuntary


        liquidation, dissolution, or winding up of the Corporation, as provided
        for in the Corporations Code of the State of California, the holders of
        the Common Stock shall be entitled to receive all the remaining assets
        of the Corporation.

                (3) Each holder of Common Stock shall have one (1) vote in
        respect of each share of stock held by him, subject, however, to such
        special voting rights by class as are or may be granted to holders of
        Serial Preferred Stock.

        3. That the foregoing Amendment of Articles of Incorporation has been
duly approved by the required vote of shareholders in accordance with Section
902 of the California Corporations Code. The total number of outstanding shares
of the Corporation is 1,216,573. The number of shares voting in favor of the
Amendment equaled or exceeded the vote required. The percentage vote required

        4. That the foregoing Amendment of Articles of Incorporation has been

                             OF CVB FINANCIAL CORP.

      The undersigned, D. Linn Wiley and Donna Marchesi do hereby certify:

      1. That they are the duly elected and acting President and Secretary,
respectively, of CVB Financial Corp., a California corporation (the
"CORPORATION").

      2. That, pursuant to the resolutions set forth in Paragraph 4 hereof, the
Board of Directors of the Corporation has authorized the issuance of, and
designated the rights, preferences, privileges and restrictions of one million
(1,000,000) shares of Series A Participating Preferred Stock. The Corporation's
Articles of Incorporation, as amended, authorize the issuance of up to twenty
million (20,000,000) shares of Preferred Stock.

      3. That none of the shares of Series A Participating Preferred Stock have
been issued by the Corporation.

      4. That pursuant to the authority conferred upon the Board of Directors by
the Articles of Incorporation of the said Corporation, the said Board of
Directors on June 21, 2000 adopted the following resolution creating a series of
one million (1,000,000) shares of Preferred Stock designated as Series A
Participating Preferred Stock:

      "RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation by its Articles of Incorporation, the Board of Directors does
hereby provide for the issue of a series of Preferred Stock of the Corporation
and does hereby fix and herein state and express the designations, powers,
preferences and relative and other special rights and the qualifications,
limitations and restrictions of such series of Preferred Stock as follows:

      Section 1. DESIGNATION AND AMOUNT. The shares of such series shall be
designated as "SERIES A PARTICIPATING PREFERRED STOCK." The number of shares
constituting such series shall be one million (1,000,000) shares. Such number of
shares may be increased or decreased by resolution of the Board of Directors;
provided, that no decrease shall reduce the number of shares of Series A
Participating Preferred Stock to a number less than the number of shares then
outstanding plus the number of shares reserved for issuance upon the exercise of
outstanding options, rights or warrants or upon the conversion of any
outstanding securities issued by the Corporation convertible into Series A
Participating Preferred Stock.

      Section 2. DIVIDENDS AND DISTRIBUTIONS.

      (a) Subject to the prior and superior right of the holders of any shares
of any series of Preferred Stock (or any similar stock) ranking prior and
superior to the shares of Series A Participating Preferred Stock with respect to
dividends, the holders of shares of Series A Participating Preferred Stock, in
preference to the holders of Common Stock of the Company, and of any other
junior stock, shall be entitled to receive when, as and if declared by the Board
of Directors out of funds legally available for the purpose, quarterly dividends
payable in cash on the last day of March, June, September and December in each
year (each such date being


                                       1




referred to herein as a "QUARTERLY DIVIDEND PAYMENT DATE"), commencing on the
first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Participating Preferred Stock, in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $1.00 or (b)
subject to the provision for adjustment hereinafter set forth, 1,000 times the
aggregate per share amount of all cash dividends, and 1,000 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date, or, with respect to the first Quarterly
Dividend Payment Date, since the first issuance of any share or fraction of a
share of Series A Participating Preferred Stock. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount to which
holders of shares of Series A Participating Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction, the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

      (b) The Corporation shall declare a dividend or distribution on the Series
A Participating Preferred Stock as provided in paragraph (a) above immediately
after it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided that, in the event no
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $1.00 per shares on the Series A
Participating Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

      (c) Dividends shall begin to accrue on outstanding shares of Series A
Participating Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Series A Participating Preferred
Stock, unless the date of issue of such shares is prior to the record date for
the first Quarterly Dividend Payment Date, in which case dividends on such
shares shall begin to accrue from the date of issue of such shares, or unless
the date of issue is a Quarterly Dividend Payment Date or is a date after the
record date for the determination of holders of shares of Series A Participating
Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue from such Quarterly Dividend Payment Date. Accrued but unpaid
dividends shall not bear interest. Dividends paid on the shares of Series A
Participating Preferred Stock in an amount less than the total amount of such
dividends at the time accrued and payable on such shares shall be allocated pro
rata on a share-by-share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of holders of
shares of Series A Participating Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not less
than ten (10) nor more than sixty (60) days prior to the date fixed for the
payment thereof.


                                       2



      Section 3. VOTING RIGHTS. The holders of shares of Series A Participating
Preferred Stock shall have the following voting rights:

      (a) Each share of Series A Participating Preferred Stock shall entitle the
holder thereof to 1,000 votes on all matters submitted to a vote of the
shareholders of the Corporation.

      (b) Except as otherwise provided herein, in any other Certificate of
Determination, or by law, the holders of shares of Series A Participating
Preferred Stock and the holders of shares of Common Stock shall vote together as
one class on all matters submitted to a vote of shareholders of the Corporation.

      (c) Except as required by law, holders of Series A Participating Preferred
Stock shall have no special voting rights and their consent shall not be
required (except to the extent they are entitled to vote with holders of Common
Stock as set forth herein) for taking any corporate action.

      Section 4. CERTAIN RESTRICTIONS.

      (a) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Participating Preferred Stock as provided in Section 2
are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Participating
Preferred Stock outstanding shall have been paid in full, the Corporation shall
not:

         (i) declare or pay dividends on, make any other distributions on, or
redeem or purchase or otherwise acquire for consideration any shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Participating Preferred Stock;

         (ii) declare or pay dividends on, make any other distributions on any
shares of stock ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with Series A Participating Preferred Stock, except
dividends paid ratably on the Series A Participating Preferred Stock and all
such parity stock on which dividends are payable or in arrears in proportion to
the total amounts to which the holders of all such shares are then entitled;

         (iii) redeem or purchase or otherwise acquire for consideration shares
of any stock ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with the Series A Participating Preferred Stock,
provided that the Corporation may at any time redeem, purchase or otherwise
acquire shares of any such parity stock in exchange for shares of any stock of
the Corporation ranking junior (either as to dividends or upon dissolution,
liquidation or winding up) to the Series A Participating Preferred Stock;

         (iv) purchase or otherwise acquire for consideration any shares of
Series A Participating Preferred Stock, or any shares of stock ranking on a
parity with the Series A Participating Preferred Stock, except in accordance
with a purchase offer made in writing or by publication (as determined by the
Board of Directors) to all holders of such shares upon such terms as the Board
of Directors, after consideration of the respective annual dividend rates and


                                       3



other relative rights and preferences of the respective series and classes,
shall determine in good faith will result in fair and equitable treatment among
the respective series or classes.

        (b) The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (a) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

      Section 5. REACQUIRED SHARES. Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein and in the Articles of Incorporation, as then amended.

      Section 6. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made (1)
to the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Participating Preferred
Stock unless, prior thereto, the holders of shares of Series A Participating
Preferred Stock shall have received an amount per share equal to $1,000.00, plus
an amount equal to accrued and unpaid dividends and distributions thereon,
whether or not declared, to the date of such payment, provided that the holders
of shares of Series A Participating Preferred Stock shall be entitled to receive
an aggregate amount per share, subject to the provision for adjustment
hereinafter set forth, equal to the aggregate amount to be distributed per share
to holder of shares of Common Stock, or (2) to the holders of shares of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution or
winding up) with the Series A Preferred Stock, except distributions made ratably
on the Series A Participating Preferred Stock and all such parity stock in
proportion to the total amount to which the holders of all such shares are
entitled upon such liquidation, dissolution or winding up. In the event the
Corporation shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
aggregate amount to which holders of shares of Series A Participating Preferred
Stock were entitled immediately prior to such event under the proviso in clause
(1) of the preceding sentence shall be adjusted by multiplying such amount by a
fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock outstanding immediately prior to such event.

      Section 7. CONSOLIDATION, MERGER, ETC. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Participating Preferred Stock shall at the same time be similarly
exchanged or changed in an amount per share, subject to the provision for
adjustment hereinafter set forth, equal to one thousand (1,000) times the
aggregate amount of


                                       4



stock, securities, cash and/or any other property (payable in kind) as the case
may be, into which or for which each share of Common Stock is changed or
exchanged. In the event the Corporation shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the amount set forth in the preceding sentence with respect to
the exchange or change of shares of Series A Participating Preferred Stock shall
be adjusted by multiplying such amount by a fraction, the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

      Section 8. NO REDEMPTION. The shares of Series A Participating Preferred
Stock shall not be redeemable.

      Section 9. RANKING. The Series A Participating Preferred Stock shall rank
junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

      Section 10. AMENDMENT. The Articles of Incorporation of the Corporation
shall not be further amended in any manner which would materially alter or
change the powers, preference or special rights of the Series A Participating
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of a majority of the outstanding shares of Series A Participating
Preferred Stock, voting separately as a class.

      Section 11. FRACTIONAL SHARES. Series A Participating Preferred Stock may
be issued in fractions of a share which shall entitle the holder, in proportion
to such holder's fractional shares, to exercise voting rights, receive
dividends, participate in distributions and to have the benefit of all other
rights of holders of Series A Participating Preferred Stock.

      RESOLVED FURTHER, that the President or any Vice President and the
Secretary or any Assistant Secretary of this corporation be, and they hereby
are, authorized and directed to prepare and file a Certificate of Determination
in accordance with the foregoing resolution and the provisions of California law
and to take such actions as they may deem necessary or appropriate to carry out
the intent of the foregoing resolution."
