books of the corporation is returned to the corporation by the United States

communication addressed to the place where the principal executive office of the
corporation is situated, or if published at least once in some newspaper of
general circulation in the county in which said principal executive office is

sixty (60) days before each annual meeting. Any such notice shall be deemed to

      Such notices shall specify:

               (i) the place, the date, and the hour of such meeting;

               (ii) those matters which the board, at the time of the mailing of

               (iii) if directors are to be elected, the names of nominees
intended at the time of the notice to be presented by management for election;

                                        2

Corporation Law, (d) voluntary dissolution of the corporation, or (e) a
distribution in dissolution other than in accordance with the rights of
outstanding preferred shares, if any; and,

               (v) such other matters, if any, as may be expressly required by
statute.

      Section 2.3 SPECIAL MEETINGS.

            (a) Calling of. Special meetings of the shareholders, for the
purpose of taking any action permitted by the shareholders under the General
Corporation Law and the articles of incorporation of this corporation, may be
called at any time by the chairman of the board, the president, the Board of
Directors or by one or more shareholders holding not less than ten percent (10%)
of the votes at the meeting. A shareholder entitled to call a special meeting of
shareholders for any proper purpose shall submit a request therefor in writing
directed to the chairman of the board, president, vice president, or secretary.

            (b) Time and Notice of. Upon receipt of such request, the
corporation forthwith shall cause notice to be given to shareholders entitled to
vote that a meeting will be held at a time requested by the person or persons
calling the meeting, which time shall be not less than thirty-five (35) nor more
than sixty (60) days after receipt of the request. If such notice is not given
within twenty (20) days after receipt of such request, the persons calling for
the meeting may give notice thereof in the manner provided by these bylaws.
Except in special cases where other express provision is made by statute, notice
of such special meetings shall be given in the same manner as for annual
meetings of shareholders. In addition to the matters required by items (i) and,
if applicable (iii) of Section 2.2(d), notice of any special meeting shall
specify the general nature of the business to be transacted, and no other
business may be transacted at such meeting.

      Section 2.4 QUORUM. A majority of the shares entitled to vote, represented
in person or by proxy, shall constitute a quorum for the transaction of business
at a meeting of shareholders. The shareholders present at a duly called or held
meeting at which a quorum is present may continue to do business until
adjournment, notwithstanding

                                        3


the withdrawal of enough shareholders to leave less than a quorum, if any action
taken (other than adjournment) is approved by at least a majority of the shares
required to constitute a quorum.

      Section 2.5 ADJOURNED MEETING AND NOTICE THEREOF. Any shareholders'
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the vote of a majority of the shares, the holders of which
are either present in person or represented by proxy thereat. When any meeting
of shareholders is adjourned to another time or place, written notice need not
be given of the adjourned meeting if the time and place are announced at a
meeting at which the adjournment is taken, unless a new record date for the
adjourned meeting is fixed, or unless the adjournment is for more than
forty-five (45) days in which case the Board of Directors shall set a new record
date. For any adjourned meeting requiring notice, such notice shall be given to
each shareholder of record entitled to vote at the adjourned meeting in
accordance with the provisions of Sections 2.2 and 2.3. At any adjourned meeting
the corporation may transact any business which might have been transacted at
the original meeting.

      Section 2.6 VOTING.

            (a) Record Date. Unless a record date for voting purposes be fixed
as provided in Section 5.1 of Article V of these bylaws then, subject to the
provisions of Sections 702 and 704 of the General Corporation Law of California
(relating to voting of shares held by a fiduciary, in the name of a
corporation, or in joint ownership), only persons in whose names shares entitled
to vote standing on the stock records of the corporation at the close of
business on the business day next preceding the day on which notice of the
meeting is given or if such notice is waived, at the close of business on the
business day next preceding the day on which the meeting of shareholders is
held, shall be entitled to vote at such meeting, and such day shall be the
record date for such meeting.

            (b) Ballot. The shareholders' vote may be oral or by ballot;
provided, however, all elections for directors must be by ballot if demand for
election by ballot is made by a shareholder at the meeting and before the voting
begins. If a quorum is present, except with respect to election of directors,
the affirmative vote of the majority of the shares represented at the meeting
and entitled to vote on any matter shall be the act of the shareholders, unless
the vote of a greater number or voting by classes is required by the General
Corporation Law of California or the articles of incorporation.

                                        4


            (c) At a shareholders' meeting at which directors are to be elected,
no shareholder shall be entitled to cumulate votes (i.e., cast for any one or
more candidates a number of votes greater than the number of the shareholder's
shares) unless the candidates' names have been properly placed in nomination
prior to commencement of the voting and a shareholder has given notice prior to
commencement of the voting of the shareholder's intention to cumulate votes. If
any shareholder has given such a notice, then every shareholder entitled to vote
may cumulate votes for candidates in nomination and give one candidate a number
of votes equal to the number of directors to be elected multiplied by the number
of votes to which that shareholder's shares are entitled, or distribute the
shareholder's votes on the same principle among any or all of the candidates, as
the shareholder thinks fit. The candidates receiving the highest number of
votes, up to the number of directors to be elected, shall be elected.

      Section 2.7 VALIDATION OF DEFECTIVELY CALLED OR NOTICED MEETINGS. The
transactions of any meeting of shareholders, either annual or special, however
called and noticed, and wherever held, shall be as valid as though had at a
meeting duly held after regular call and notice, if a quorum be present either
in person or by proxy, and if, either before or after the meeting, each of the
persons entitled to vote, who was not present in person or by proxy, signs a
written waiver of notice or a consent to a holding of the meeting, or an
approval of the minutes. The waiver of notice or consent need not specify either
the business to be transacted or the purpose of any annual or special meeting of
shareholders, except that if action is taken or proposed to be taken for
approval of any of those matters specified in Section 2.2(d)(iv) of Article II,
the waiver of notice or consent shall state the general nature of the proposal.
All such waivers, consents or approvals shall be filed with the corporate
records or made a part of the minutes of the meeting.

      Attendance by a person at a meeting shall also constitute a waiver of
notice of that meeting, except when the person objects, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver of
any right to object to the consideration of matters required by the General
Corporation Law of the State of California to be included in the notice but not
so included, if such objection is expressly made at the meeting.

      Section 2.8 ACTION WITHOUT MEETING.

            (a) Action by Written Consent and Notice Thereof. Any action which
may be taken at any annual or

                                        5


special meeting of shareholders, including the election of directors, may be
taken without a meeting and without prior notice if a consent in writing,
setting forth the action so taken, is signed by the holders of outstanding share
having not less than the minimum number of votes that would be necessary to
authorize or take that action at a meeting at which all shares entitled to vote
on that action were present and voted. If the consents of all shareholders
entitled to vote have been solicited in writing, and if the unanimous written
consents of all shareholders have not been obtained, notice shall be given as
provided herein.

               (i) Notice shall be given of any proposed shareholder approval
of, (a) a contract or other transaction with an interested director, (b)
indemnification of an agent of the corporation as authorized by section 3.16 of
Article III of these bylaws, (c) a reorganization of the corporation as defined
in Section 181 of the General Corporation Law of California, or (d) a
distribution in dissolution other than in accordance with the rights of
outstanding preferred shares, if any. The notice referred to herein shall be
given at least ten (10) days before the consummation of the action authorized by
such approval.

            (ii) Prompt notice of the taking of any other corporate action shall
be given to those shareholders entitled to vote who have not consented in
writing. Such notices shall be given in the manner and shall be deemed to have
been given as provided in Section 2.2 of Article II of these bylaws.

            (b) Election to Fill Vacancy. In the case of an election to fill a
vacancy on the Board of Directors which vacancy (1) was not created by removal
or (2) has not been filled by the Board of Directors in accordance with Section
3.5(b) of Article III of these Bylaws, a director may be elected to fill such
vacancy by the written consent of the holders of a majority of the outstanding
shares entitled to vote for the election of directors. An election by the
written consent of the shareholders to fill a vacancy created by removal may be
made only by the unanimous written consent of the holders of all outstanding
shares entitled to vote for the election of directors.

            (c) Filing of Consents; Record Date. All written consents of the
shareholders shall be filed with the secretary of the corporation. Unless, as
provided in Section 5.1 of Article V of these bylaws, the Board of Directors
has fixed a record date for the determination of shareholders entitled to notice
of and to give such written consent, the record date for such determination
shall be the day on which the first written consent is given.

                                        6


            (d) Revocation of Consent. Any shareholder giving a written consent,
or the shareholder's proxyholders, or a transferee of the shares of a personal
representative of the shareholder or his respective proxyholders, may revoke the
consent by a writing received by the corporation prior to the time that written
consents of the number of shares required to authorize the proposed action have
been filed with the secretary of the corporation, but may not do so thereafter.
Such revocation shall be effective upon its receipt by the secretary of the
corporation.

      Section 2.9 PROXIES. Every person entitled to vote or execute consents
shall have the right to do so either in person or by one or more agents
authorized by a written proxy executed by such person or his duly authorized
agent and filed with the secretary of the corporation. Any proxy duly executed
is not revoked and continues in full force and effect until (i) an instrument
revoking it or a duly executed proxy bearing a later date is filed with the
secretary of the corporation prior to the vote pursuant thereto, (ii) the person
executing the proxy attends the meeting and votes in person, or (iii) written
notice of the death or incapacity of the maker of such proxy is received by the
corporation before said proxy is voted and counted. In the determination of the
validity and effect of proxies, the dates contained on the forms of proxy shall
presumptively determine the order of execution of the proxies, regardless of the
postmark dates on the envelopes in which they are mailed. Unless otherwise
provided in the proxy, no proxy shall be valid after the expiration of eleven
(11) months from the date of such proxy.

      Section 2.10 INSPECTORS OF ELECTION.

            (a) Appointment, Number. In advance of any meeting of shareholders,
the Board of Directors may appoint any persons, other than nominees for office,
as inspectors of election to act at such meeting or any adjournment thereof. If
inspectors of election are not so appointed, or if any person so appointed fails
to appear or refuses to act, the chairman of any such meeting may, and on the
request of any shareholder or his proxy shall, appoint inspectors of election
(or persons to replace those who so fail or refuse) at the meeting. The number
of inspectors shall be either one (1) or three (3). If appointed at a meeting on
the request of one or more shareholders or proxies, the majority of shares
represented in person or by proxy shall determine whether one (1) or three (3)
inspectors are to be appointed.

            (b) Duties. The duties of such inspectors shall be as prescribed by
Section 707 of the General Corporation Law of California and shall include:
determining the

                                        7


number of shares outstanding and the voting power of each, the shares
represented at the meeting, the existence of a quorum, the authenticity,
validity and effect of proxies; receiving votes, ballots or consents; hearing
and determining all challenges and questions in any way arising in connection
with the right to vote; counting and tabulating all votes or consents;
determining when the polls shall close; determining the result; and such acts as
may be proper to conduct the election or vote with fairness to all shareholders.
The inspectors of election shall perform their duties impartially, in good
faith, to the best of their ability and as expeditiously as is practical. If
there are three (3) inspectors of election, the decision, act or certificate of
a majority is effective in all respects as the decision, act or certificate of
all. Any report or certificate made by the inspectors of election is prima facie
evidence of the facts stated therein.

      Section 2.11 NOMINATIONS FOR DIRECTOR. Nominations for election of members
of the Board of Directors may be made by the Board of Directors or by any
shareholder of any outstanding class of voting stock of the corporation entitled
to vote for the election of directors. Notice of intention to make any
nominations, other than by the Board of Directors, shall be made in writing and
shall be received by the President of the corporation no more than 60 days prior
to any meeting of shareholders called for the election of directors, and no more
than 10 days after the date the notice of such meeting is sent to shareholders
pursuant to Section 2.2 of these bylaws; provided, however, that if only 10
days' notice of the meeting is given to shareholders, such notice of intention
to nominate shall be received by the President of the corporation not later than
the time fixed in the notice of the meeting for the opening of the meeting. Such
notification shall contain the following information to the extent known to the
notifying shareholder: (a) the name and address of each proposed nominee; (b)
the principal occupation of each proposed nominee; (c) the number of shares of
voting stock of the corporation owned by each proposed nominee; (d) the name and
residence address of the notifying shareholder; and (e) the number of shares of
voting stock of the corporation owned by the notifying shareholder. Nominations
not made in accordance herewith shall be disregarded by the then chairman of the
meeting, and the inspectors of election shall then disregard all votes cast for
each nominee.

      The first paragraph of this Section 2.11 shall be set forth in any notice
of a shareholders' meeting, whether pursuant to Section 2.2 or Section 2.3 of
these bylaws, at which meeting the election of directors is to be considered.

                                             8


                                   ARTICLE III

                                    DIRECTORS

            Section 3.1 POWERS. Subject to any limitations of the articles of
incorporation and of these bylaws and of the General Corporation Law of
California requiring shareholder authorization or approval for a particular
action, the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the Board of
Directors. The board may delegate the management of the day-to-day operation of
the business of the corporation to a management company or other person,
provided that the business and affairs of the corporation shall be managed and
all corporate powers shall be exercised, under the ultimate direction of the
Board of Directors.

            Section 3.2 COMMITTEES. By resolution adopted by a majority of the
authorized number of directors, the board may designate an executive and other
committees, each consisting of two or more directors, to serve at the pleasure
of the board. The provisions of this Article apply to committees of the Board of
Directors and action by such committees, with such changes in the language of
those provisions as are necessary to substitute the committee and its members
for the board and its members. The board may designate one or more directors as
alternate members of any committee, who may replace any absent member at any
meeting of the committee. The appointment of members or alternate members of a
committee shall be made by the vote of a majority of the authorized number of
directors. Unless the Board of Directors shall otherwise prescribe the manner of
proceedings of any such committee, meetings of such committee may be regularly
scheduled in advance and may be called at any time by any two members thereof;
otherwise, the provisions of these bylaws with respect to notice and conduct of
meetings of the board shall govern. Any such committee, to the extent provided
in a resolution of the board, shall have all of the authority of the board,
except with respect to:

                  (i) the approval of any action for which the General
Corporation Law of California or the articles of incorporation also require
shareholder approval;

                  (ii) the filling of vacancies on the board or in any
committee;

                  (iii) the fixing of compensation of the directors for serving
on the board or on any committee;

                                        9


                  (iv) the adoption, amendment or repeal of bylaws;

                  (v) the amendment or repeal of any resolution of the board
which by its express terms is not so amendable or repealable;

                  (vi) any distribution to the shareholders, except at a rate or
in a periodic amount or within a price range determined by the board; and

                  (vii) the appointment of other committees of the board or the
members thereof.

            Section 3.3 NUMBER OF DIRECTORS. (a) The authorized number of
directors shall be not less than 7 nor more than 13. The exact number of
directors shall be fixed from time to time, within the limits specified in this
subsection, by an amendment of subsection (b) of this section adopted by the
Board of Directors.

                  (b) The exact number of directors shall be 8 until changed as
provided in subsection (a) of this section.

                  (c) The maximum or minimum authorized number of directors may
only be changed by an amendment of this section approved by the vote or written
consent of a majority of the outstanding shares entitled to vote; provided,
however, that an amendment reducing the minimum number to a number less than 5
shall not be adopted if the votes cast against its adoption at a meeting (or the
shares not consenting in the case of action by written consent) exceed 16-2/3%
of such outstanding shares; and provided further, that in no case shall the
stated maximum authorized number of directors exceed two times the stated
minimum number of authorized directors minus one.

            Section 3.4 ELECTION AND TERM OF OFFICE. The directors shall be
elected at each annual meeting of shareholders but, if any such annual meeting
is not held or the directors are not elected thereat, the directors may be
elected at any special meeting of shareholders held for that purpose. All
directors shall hold office until the next annual meeting of the shareholders
and until his successor is elected and qualified, subject to the General
Corporation Law of California and the provisions of these bylaws with respect to
vacancies on the board.

            Section 3.5 VACANCIES.

                  (a) When a Vacancy Exists. A vacancy in the Board of Directors
exists whenever any authorized position of director is not then filled by a duly
elected director,

                                       10


whether caused by death, resignation, removal, change in the authorized number
of directors or otherwise.

                  (b) Filling of Vacancies by Directors. Vacancies in the Board
of Directors, except for a vacancy created by the removal of a director (see
Section 3.5(c)) may be filled by a majority of the remaining directors, though
less than a quorum, or by a sole remaining director, and each director so
elected shall hold office until his successor is elected at an annual or a
special meeting of shareholders. If the Board of Directors accepts the
resignation of a director tendered to take effect at a future time, the Board of
Directors (or the shareholders) may elect a successor to take office when the
resignation becomes effective.

                  (c) Filling of Vacancies by Shareholders. The shareholders may
elect a director or directors at any time to fill any vacancy or vacancies not
filled by the directors. Except for an election to fill a vacancy created by the
removal of a director, any such election by written consent shall require the
consent of holders of a majority of the outstanding shares entitled to vote for
the election of directors. A vacancy in the Board of Directors created by the
removal of a director may only be filled by the vote of a majority of the shares
entitled to vote for the election of directors represented at a duly held
meeting at which a quorum is present, or by the unanimous written consent of the
holders of all of the outstanding shares entitled to vote for the election of
directors.

                  (d) Removal for Cause. The Board of Directors may declare
vacant the office of a director who has been declared of unsound mind by an
order of court or convicted of a felony.

                  (e) Removal without Cause. Any or all of the directors may be
removed without cause if such removal is approved by a majority of the
outstanding shares entitled to vote; provided, however, that no director may be
removed (unless the entire Board of Directors is removed) whenever the votes
cast against removal, or not consenting in writing to such removal, would be
sufficient to elect such director if voted cumulatively at an election at which
the same total number of votes were cast (or, if such action is taken by written
consent, all shares entitled to vote were voted) and the entire number of
directors authorized at the time of his most recent election were then being
elected.

                  (f) Resignation. Any director may resign effective upon giving
written notice to the chairman of the

                                       11


board, the president, the secretary or the Board of Directors of the
corporation, unless the notice specifies a later time for the effectiveness of
such resignation. If the resignation is effective at a future time, a successor
may be elected to take office when the resignation becomes effective.

                  (g) When Reduction in Number Effective. No reduction of the
authorized number of directors shall have the effect of removing any director
prior to the expiration of his term of office.

            Section 3.6 PLACE OF MEETING. Regular meetings of the Board of
Directors shall be held at any place within or without the State of California
which has been designated from time to time by resolution of the board. In the
absence of such designation, regular meetings shall be held at the principal
executive office of the corporation. Special meetings of the board may be held
either at a place so designated or at the principal executive office.

            Section 3.7 ANNUAL MEETING - Immediately following each annual
meeting of shareholders the Board of Directors shall hold a regular meeting at
the place of said annual meeting or at such other place as shall be fixed by the
Board of Directors, for the purpose of organization, election of officers, and
the transaction of other business. Call and notice of such meetings are hereby
dispensed with.

            Section 3.8 OTHER REGULAR MEETINGS. Other regular meetings of the
Board of Directors shall be held at such day and hour as shall be fixed from
time to time by the Board of Directors by resolution or in the bylaws. If such
day falls upon a legal holiday, then said meeting shall be held at the same time
on the next day thereafter ensuing which is a full business day. Notice of all
such regular meetings of the Board of Directors is hereby dispensed with.

            Section 3.9 SPECIAL MEETINGS. Special meetings of the Board of
Directors for any purpose or purposes shall be called at any time by the
chairman of the board, the president, any vice president, the secretary or by
any two directors. Written notice of the time and place of special meetings
shall be delivered personally to each director or communicated to each director
by telephone, or by telegraph or mail, charges prepaid, addressed to him at his
address as it is shown upon the records of the corporation or, if it is not so
shown on such records or if not readily ascertainable, at the place at which
the meetings of the directors are regularly held. In case such notice is mailed
or telegraphed, it shall be deposited in the United states mail or delivered to
the telegraph company in the place in which the

                                       12


principal executive officer of the corporation is located at least four (4) days
prior to the time of the holding of the meeting. In case such notice is
delivered, personally or by telephone, as above provided, it shall be so
delivered at least forty-eight (48) hours prior to the time of the holding of
the meeting. Such mailing, telegraphing or delivery, personally or by telephone,
as above provided, shall be due, legal and personal notice to such director. Any
notice shall state the date, place and hour of the meeting.

            Section 3.10 ACTION WITHOUT MEETING. Any action by the Board of
Directors may be taken without a meeting if all members of the board shall
individually or collectively consent in writing to such action. Such written
consent or consents shall be filed with the minutes of the proceedings of the
board and shall have the same force and effect as a unanimous vote of such
directors.

            Section 3.11 ACTION AT A MEETING; QUORUM AND REQUIRED VOTE. Presence
of a majority of the authorized number of directors at a meeting of the Board of
Directors constitutes a quorum for the transaction of business. Members of the
board may participate in a meeting through use of conference telephone or
similar communications equipment, so long as all members participating in such
meeting can hear one another. Participation in a meeting as permitted in the
preceding sentence constitutes presence in person at such meeting. Every act or
decision done or made by a majority of the directors present at a meeting duly
held at which a quorum is present shall be regarded as the act of the Board of
Directors, unless a greater number, or the same number after disqualifying one
or more directors from voting, is required by law, by the articles of
incorporation, or by these bylaws. A meeting at which a quorum is initially
present may continue to transact business notwithstanding the withdrawal of a
director, provided that any action taken is approved by at least a majority of
the required quorum for such meeting.

            Section 3.12 VALIDATION OF DEFECTIVELY CALLED OR NOTICED MEETINGS.
The transactions of any meeting of the Board of Directors, however called and
noticed or wherever held, shall be as valid as though had at a meeting duly held
after regular call and notice, if a quorum is present and if, either before or
after the meeting, each of the directors not present or who signs a written
waiver of notice or a consent to holding such meeting or an approval of the
minutes thereof. All such waivers, consents or approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

                                       13


            Section 3.13 WAIVER OF NOTICE BY ATTENDANCE. Attendance of a
director at any meeting shall constitute a waiver of notice of such meeting,
unless a director attends for the express purpose of objecting to the
transaction of any business because the meeting is not lawfully called, noticed,
or convened.

            Section 3.14 ADJOURNMENT. A majority Of the directors present,
whether or not a quorum is present, may adjourn any meeting to another time and
place. If the meeting is adjourned for more than 24 hours, written notice of any
adjournment to another time or place shall be given prior to the time of the
adjourned meeting to the directors who were not present at the time of the
adjournment.

            Section 3.15 FEES AND COMPENSATION. Directors and members of
committees may receive such compensation, if any, for their services, and such
reimbursement for expenses, as may be fixed or determined by resolution of the
board.

            Section 3.16 INDEMNIFICATION OF CORPORATE AGENTS. The corporation
may indemnify each of its agents against expenses, judgments, fines, settlements
and other amounts, actually and reasonably incurred by such person having been
made or having been threatened to be made a party to a proceeding to the fullest
extent possible by the provisions of Section 317 of the General Corporation Law
of California and the corporation may advance the expenses reasonably expected
to be incurred by such agent in defending any such proceeding upon receipt of
the undertaking required by Section 317(f). The terms "agent," "proceeding" and
"expense" made in this Section 3.16 shall have the same meaning as such terms in
said Section 317.

            Section 3.17 TRANSACTIONS BETWEEN CORPORATIONS AND DIRECTORS.

                  (a) No contract or other transaction between the corporation
and one or more of its directors, or between the corporation and any
corporation, firm or association in which one or more of its directors has a
material financial interest, is either void or voidable because such director or
directors or such other corporation, firm or association are parties or because
such director or directors are present at the meeting of the board or a
committee thereof which authorizes, approves or ratifies the contract or
transaction, if

                        (1) the material facts as to the transaction and as to
such director's interest are fully disclosed or known to the shareholders and
such contract or transaction

                                       14


is approved in good faith by the affirmative vote of a majority of the shares
entitled to vote represented at a duly held meeting at which a quorum is present
or by the written consent of shareholders, with the shares owned by the
interested director or directors not being entitled to vote thereon;

                        (2) the material facts as to the transaction and as to
such director's interest are fully disclosed or known to the board or committee,
and the board or committee authorizes, approves or ratifies the contract or
transaction in good faith by a vote sufficient without counting the vote of the
interested director or directors and the contract or transaction is just and
reasonable as to the corporation at the time it is authorized, approved or
ratified; or

                        (3) as to contracts or transactions not approved as
provided in paragraph (a) or (b) of this subdivision, the person asserting the
validity of the contract or transaction sustains the burden of proving that the
contract or transaction was just and reasonable as to the corporation at the
time it was authorized, approved or ratified.

                  (b) No contract or other transaction between a corporation and
any corporation or association of which one or more of its directors are
directors is either void or voidable because such director or directors are
present at the meeting of the board or a committee thereof which authorizes,
approves or ratifies the contract or transaction, if

                        (1) The material facts as to the transaction and as to
such director's other directorship are fully disclosed or known to the board or
committee, and the board or committee authorizes, approves or ratifies the
contract or transaction in good faith by a vote sufficient without counting the
vote of the common director or directors or the contract or transaction is
approved by the shareholders (Section 153) of the General Corporation Law in
good faith, or

                        (2) As to contracts or other transactions not approved
as provided in paragraph (1) of this subdivision, the contract or transaction is
just and reasonable as to the corporation at the time it is authorized,
approved or ratified.

            This subsection (b) does not apply to contracts or transactions
covered by subsection (a).

                  (c) A mere common directorship does not consitute a material
financial interest within the meaning of subsection (a) of this Section 3.17. A
director is not

                                       15


interested within the meaning of subsection (a) of this Section 3.17 in a
resolution fixing the compensation of another director as a director, officer or
employee of the corporation, notwithstanding the fact that the first director is
also receiving compensation from the corporation.

                  (d) Interested or common directors may be counted in
determining the presence of a quorum at a meeting of the board or a committee
thereof which authorizes, approves or ratifies a contract or transaction.

before such certificate is issued, it may be issued by the corporation with the
same effect as if such person were an officer, transfer agent or registrar at
the date of issue.

            Section 5.8 LOST, STOLEN OR DESTROYED CERTIFICATES. No new
certificates for shares shall be issued to replace an old certificate unless the
latter is surrendered and cancelled at the same time; provided, however, that

                               (Bylaw Amendment)

            I, the undersigned, do hereby certify:

            1. That I am the duly elected and acting Secretary of CVB FINANCIAL
CORP., a California corporation (the "Company"); and

            2. That the following is a true and correct copy of resolutions
amending the Bylaws of the Company adopted with a quorum present at a special
meeting of the Board of Directors of the Company held on the 22nd day of
February, 1988:

            WHEREAS, California has recently enacted significant amendments to
      the General Corporation Law that permit, among other things, corporations
      to include in their Articles of Incorporation provisions that would
      eliminate or limit the personal liability of a director for monetary
      damages in an action brought by or in the right of the corporation for
      breach of the director's duty to the corporation and its shareholders as
      well as permit more extensive indemnification of corporate directors,
      officers and agents;

            WHEREAS, the Board of Directors has adopted, subject to shareholder
      and regulatory approval, certain amendments to the Articles of
      Incorporation to implement these new provisions of the General Corporation
      Law; and

            WHEREAS, it is deemed by the Board of Directors to be in the best
      interests of the Company, subject to shareholder and regulatory approval
      of the aforementioned amendments to the Articles of incorporation, to
      adopt certain amendments to the Bylaws to implement these new provisions
      of the General Corporation Law.

            NOW, THEREFORE, BE IT HEREBY RESOLVED, Subject to shareholder and
      regulatory approval of the aforementioned amendments to the Articles of
      Incorporation, that ARTICLE III, Section 3.16 of the Bylaws of the Company
      entitled "INDEMNIFICATION OF CORPORATE AGENTS" be, and it hereby is,
      deleted; and

            BE IT FURTHER RESOLVED, subject to shareholder and regulatory
      approval of the aforementioned amendments to the Articles of
      Incorporation, that the Bylaws of the Company be, and they hereby are,
      amended to add the



      following new ARTICLE VII, which provides in its entirety as follows:

                                  "ARTICLE VII

       INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND OTHER AGENTS

            Section 7.1 PERMISSIVE INDEMNIFICATION. The corporation shall have
      the power, to the extent and in the manner permitted by the California
      Corporations Code (the "Code"), to indemnify each of its directors,
      officers, employees and agents against expenses (as defined in Section
      317(a) of the Code), judgments, fines, settlements, and other amounts
      actually and reasonably incurred in connection with any proceeding (as
      defined in Section 317(a) of the Code), arising by reason of the fact that
      such person is or was an agent of the corporation. For purposes of this
      ARTICLE VII, an "employee" or "agent" of the corporation includes any
      person (i) who is or was an employee or agent of the corporation, (ii) who
      is or was serving at the request of the corporation as an employee or
      agent of another corporation, partnership, joint venture, trust or other
      enterprise, or (iii) who was an employee or agent of the corporation which
      was a predecessor corporation of the corporation or of another enterprise
      at the request of such predecessor corporation.

            Section 7.2 PAYMENT OF EXPENSES IN ADVANCE. Expenses incurred in
      defending any civil or criminal action or proceeding for which
      indemnification is permitted pursuant to Section 7.1 following
      authorization thereof by the Board of Directors, may be paid by the
      corporation in advance of the final disposition of such action or
      proceeding upon receipt of an undertaking by or on behalf of the
      indemnified party to repay such amount if it shall ultimately be
      determined that the indemnified party is not entitled to be indemnified as
      authorized in this ARTICLE VII.

            Section 7.3 INDEMNITY NOT EXCLUSIVE. The indemnification provided by
      this ARTICLE VII shall not be deemed exclusive of any other rights to
      which those seeking indemnification may be entitled under any bylaw,
      agreement, vote of shareholders or disinterested directors or otherwise,
      both as to action in an official capacity and as to action in another
      capacity while holding such office, to the extent that such additional
      rights to indemnification are authorized in the Articles of Incorporation.

                                        2


            Section 7.4 INSURANCE INDEMNIFICATION. The corporation shall have
      the power to purchase and maintain insurance on behalf of any person who
      is or was an agent of the corporation against any liability asserted
      against or incurred by such person in such capacity or arising out of such
      person's status as such, whether or not the corporation would have the
      power to indemnify him against such liability under the provisions of this
      ARTICLE VII.

            Section 7.5 CONFLICTS. No indemnification or advance shall be made
      under this ARTICLE VII, except where such indemnification or advance is
      mandated by law or the order, judgment or decree of any court of competent
      jurisdiction, in any circumstance where it appears:

            (1) That it would be inconsistent with a provision of the Articles
      of Incorporation, these bylaws, a resolution of the shareholders or an
      agreement in effect at the time of the accrual of the alleged cause of the
      action asserted in the proceeding in which the expenses were incurred or
      other amounts were paid, which prohibits or otherwise limits
      indemnification; or

            (2) That it would be inconsistent with any condition expressly
      imposed by a court in approving a settlement."

      I certify that the foregoing is true and correct to the best of my
knowledge.

      Executed this 22nd day of February, 1988.
