                                CORPORATE OFFICES

        1.1    PRINCIPAL OFFICE

        The board of directors shall fix the location of the principal executive
office of the corporation at any place within or outside the State of
California. If the principal executive office is located outside such state and
the corporation has one or more business offices in such state, then the board
of directors shall fix and designate a principal business office in the State of
California.

        1.2    OTHER OFFICES

        The board of directors may at any time establish branch or subordinate
offices at any place or places where the corporation is qualified to do
business.


                                   ARTICLE II

                            MEETINGS OF SHAREHOLDERS

        2.1    PLACE OF MEETINGS

        Meetings of shareholders shall be held at any place within or outside
the State of California designated by the board of directors. In the absence of
any such designation, shareholders' meetings shall be held at the principal
executive office of the corporation.

        2.2    ANNUAL MEETING

        The annual meeting of shareholders shall be held each year on a date and
at a time designated by the board of directors. In the absence of such
designation, the annual meeting of shareholders shall be held on the third
Wednesday of May in each year at 10 am. However, if such day falls on a legal
holiday, then the meeting

<PAGE>   2

shall be held at the same time and place on the next succeeding full business
day. At the meeting, directors shall be elected, and any other proper business
may be transacted.

        2.3    SPECIAL MEETING

        A special meeting of the shareholders may be called at any time by the
board of directors, or by the chairman of the board, or by the president, or by
one or more shareholders holding shares in the aggregate entitled to cast not
less than ten percent (10%) of the votes at that meeting.

        If a special meeting is called by any person or persons other than the
board of directors or the president or the chairman of the board, then the
request shall be in writing, specifying the time of such meeting and the general
nature of the business proposed to be transacted, and shall be delivered
personally or sent by registered mail or by telegraphic or other facsimile
transmission to the chairman of the board, the president, any vice president or
the secretary of the corporation. The officer receiving the request shall cause
notice to be promptly given to the shareholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.5 of these bylaws, that a meeting will
be held at the time requested by the person or persons calling the meeting, so
long as that time is not less than thirty-five (35) nor more than sixty (60)
days after the receipt of the request. If the notice is not given within twenty
(20) days after receipt of the request, then the person or persons requesting
the meeting may give the notice. Nothing contained in this paragraph of this
Section 2.3 shall be construed as limiting, fixing or affecting the time when a
meeting of shareholders called by action of the board of directors may be held.

        2.4    NOTICE OF SHAREHOLDERS' MEETINGS

        All notices of meetings of shareholders shall be sent or otherwise given
in accordance with Section 2.5 of these bylaws not less than ten (10) (or, if
sent by third-class mail pursuant to Section 2.5 of these bylaws, thirty (30))
nor more than sixty (60) days before the date of the meeting. The notice shall
specify the place, date, and hour of the meeting and (i) in the case of a
special meeting, the general nature of the business to be transacted (no
business other than that specified in the notice may be transacted) or (ii) in
the case of the annual meeting, those matters which the board of directors, at
the time of giving the notice, intends to present for action by the shareholders
(but subject to the provisions of the next paragraph of this Section 2.4 any
proper



                                      -2-
<PAGE>   3

matter may be presented at the meeting for such action). The notice of any
meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

        If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California (the
"Code"), (ii) an amendment of the articles of incorporation, pursuant to Section
902 of the Code, (iii) a reorganization of the corporation, pursuant to Section
1201 of the Code, (iv) a voluntary dissolution of the corporation, pursuant to
Section 1900 of the Code, or (v) a distribution in dissolution other than in
accordance with the rights of outstanding preferred shares, pursuant to Section
2007 of the Code, then the notice shall also state the general nature of that
proposal.

        2.5    MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

        Written notice of any meeting of shareholders shall be given either (i)
personally or (ii) by first-class mail or (iii) by third-class mail but only if
the corporation has outstanding shares held of record by five hundred (500) or
more persons (determined as provided in Section 605 of the Code) on the record
date for the shareholders' meeting, or (iv) by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the shareholder at the address of that shareholder
appearing on the books of the corporation or given by the shareholder to the
corporation for the purpose of notice. If no such address appears on the
corporation's books or is given, notice shall be deemed to have been given if
sent to that shareholder by mail or telegraphic or other written communication
to the corporation's principal executive office, or if published at least once
in a newspaper of general circulation in the county where that office is
located. Notice shall be deemed to have been given at the time when delivered
personally or deposited in the mail or sent by telegram or other means of
written communication.

        If any notice addressed to a shareholder at the address of that
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at that address, then all future notices or reports shall be deemed to have been
duly given without further mailing if the same shall be available to the
shareholder on written demand of the shareholder at the principal



                                      -3-
<PAGE>   4

executive office of the corporation for a period of one (1) year from the date
of the giving of the notice.

        An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

        2.6    QUORUM

        The presence in person or by proxy of the holders of a majority of the
shares entitled to vote thereat constitutes a quorum for the transaction of
business at all meetings 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 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.

        2.7    ADJOURNED MEETING; NOTICE

        Any shareholders' meeting, annual or special, whether or not a quorum is
present, may be adjourned from time to time by the vote of the majority of the
shares represented at that meeting, either in person or by proxy. In the absence
of a quorum, no other business may be transacted at that meeting except as
provided in Section 2.6 of these bylaws.

        When any meeting of shareholders, either annual or special, is adjourned
to another time or place, notice need not be given of the adjourned meeting if
the time and place are announced at the meeting at which the adjournment is
taken. However, if a new record date for the adjourned meeting is fixed or if
the adjournment is for more than forty-five (45) days from the date set for the
original meeting, then notice of the adjourned meeting shall be given. Notice of
any such adjourned meeting shall be given to each shareholder of record entitled
to vote at the adjourned meeting in accordance with the provisions of Sections
2.4 and 2.5 of these bylaws. At any adjourned meeting the corporation may
transact any business which might have been transacted at the original meeting.

        2.8    VOTING

        The shareholders entitled to vote at any meeting of shareholders shall
be determined in accordance with the provisions of



                                      -4-
<PAGE>   5

Section 2.11 of these bylaws, subject to the provisions of Sections 702 through
704 of the Code (relating to voting shares held by a fiduciary, in the name of a
corporation or in joint ownership).

        The shareholders' vote may be by voice vote or by ballot; provided,
however, that any election for directors must be by ballot if demanded by any
shareholder at the meeting and before the voting has begun.

        Except as provided in the last paragraph of this Section 2.8, or as may
be otherwise provided in the articles of incorporation, each outstanding share,
regardless of class, shall be entitled to one vote on each matter submitted to a
vote of the shareholders. Any shareholder entitled to vote on any matter may
vote part of the shares in favor of the proposal and refrain from voting the
remaining shares or, except when the matter is the election of directors, may
vote them against the proposal; but, if the shareholder fails to specify the
number of shares which the shareholder is voting affirmatively, it will be
conclusively presumed that the shareholder's approving vote is with respect to
all shares which the shareholder is entitled to vote.

        If a quorum is present, the affirmative vote of the majority of the
shares represented and voting at a duly held meeting (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or a vote by
classes is required by the Code or by the articles of incorporation.

        At a shareholders' meeting at which directors are to be elected, a
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes which such shareholder normally
is entitled to cast) if the candidates' names have been placed in nomination
prior to commencement of the voting and the 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 either (i) by
giving 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
normally entitled or (ii) by distributing 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 affirmative votes, up to the number
of directors to be elected,



                                      -5-
<PAGE>   6

shall be elected; votes against any candidate and votes withheld shall have no
legal effect.

        2.9    VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

        The transactions of any meeting of shareholders, either annual or
special, however called and noticed, and wherever held, shall be as valid as
though they had been taken 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 person entitled to vote, who was not present in person
or by proxy, signs a written waiver of notice or a consent to the holding of the
meeting or an approval of the minutes thereof. The waiver of notice or consent
or approval 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 the
second paragraph of Section 2.4 of these bylaws, the waiver of notice or consent
or approval shall state the general nature of the proposal. All such waivers,
consents, and 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 and presence at 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. Attendance at a meeting is not a waiver of
any right to object to the consideration of matters required by the Code to be
included in the notice of the meeting but not so included, if that objection is
expressly made at the meeting.

        2.10   SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        Any action which may be taken at any annual or special meeting of
shareholders 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 shares 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.

        In the case of election of directors, such a consent shall be effective
only if signed by the holders of all outstanding shares entitled to vote for the
election of directors. However, a director may be elected at any time to fill
any vacancy on the board of directors, provided that it was not created by
removal of a director and that it has not been filled by the directors, by the
writ-


                                      -6-
<PAGE>   7

ten consent of the holders of a majority of the outstanding shares entitled to
vote for the election of directors.

        All such consents shall be maintained in the corporate records. Any
shareholder giving a written consent, or the shareholder's proxy holders, or a
transferee of the shares, or a personal representative of the shareholder, or
their respective proxy holders, may revoke the consent by a writing received by
the secretary of the corporation before written consents of the number of shares
required to authorize the proposed action have been filed with the secretary.

        If the consents of all shareholders entitled to vote have not been
solicited in writing and if the unanimous written consent of all such
shareholders has not been received, then the secretary shall give prompt notice
of the corporate action approved by the shareholders without a meeting. Such
notice shall be given to those shareholders entitled to vote who have not
consented in writing and shall be given in the manner specified in Section 2.5
of these bylaws. In the case of approval of (i) a contract or transaction in
which a director has a direct or indirect financial interest, pursuant to
Section 310 of the Code, (ii) indemnification of a corporate "agent," pursuant
to Section 317 of the Code, (iii) a reorganization of the corporation, pursuant
to Section 1201 of the Code, and (iv) a distribution in dissolution other than
in accordance with the rights of outstanding preferred shares, pursuant to
Section 2007 of the Code, the notice shall be given at least ten (10) days
before the consummation of any action authorized by that approval.

        2.11   RECORD DATE FOR SHAREHOLDER NOTICE; VOTING; GIVING
               CONSENTS

        For purposes of determining the shareholders entitled to notice of any
meeting or to vote thereat or entitled to give consent to corporate action
without a meeting, the board of directors may fix, in advance, a record date,
which shall not be more than sixty (60) days nor less than ten (10) days before
the date of any such meeting nor more than sixty (60) days before any such
action without a meeting, and in such event only shareholders of record on the
date so fixed are entitled to notice and to vote or to give consents, as the
case may be, notwithstanding any transfer of any shares on the books of the
corporation after the record date, except as otherwise provided in the Code.

        If the board of directors does not so fix a record date:



                                      -7-
<PAGE>   8

               (a) the record date for determining shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day on which notice is given or,
if notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held; and

               (b) the record date for determining shareholders entitled to give
consent to corporate action in writing without a meeting, (i) when no prior
action by the board has been taken, shall be the day on which the first written
consent is given, or (ii) when prior action by the board has been taken, shall
be at the close of business on the day on which the board adopts the resolution
relating to that action, or the sixtieth (60th) day before the date of such
other action, whichever is later.

        The record date for any other purpose shall be as provided in Article
VIII of these bylaws.

        2.12   PROXIES

        Every person entitled to vote for directors, or on any other matter,
shall have the right to do so either in person or by one or more agents
authorized by a written proxy signed by the person and filed with the secretary
of the corporation. A proxy shall be deemed signed if the shareholder's name is
placed on the proxy (whether by manual signature, typewriting, telegraphic
transmission or otherwise) by the shareholder or the shareholder's
attorney-in-fact. A validly executed proxy which does not state that it is
irrevocable shall continue in full force and effect unless (i) the person who
executed the proxy revokes it prior to the time of voting by delivering a
writing to the corporation stating that the proxy is revoked or by executing a
subsequent proxy and presenting it to the meeting or by voting in person at the
meeting, or (ii) written notice of the death or incapacity of the maker of that
proxy is received by the corporation before the vote pursuant to that proxy is
counted; provided, however, that no proxy shall be valid after the expiration of
eleven (11) months from the date of the proxy, unless otherwise provided in the
proxy. The dates contained on the forms of proxy presumptively determine the
order of execution, regardless of the postmark dates on the envelopes in which
they are mailed. The revocability of a proxy that states on its face that it is
irrevocable shall be governed by the provisions of Sections 705(e) and 705(f) of
the Code.

        2.13   INSPECTORS OF ELECTION



                                      -8-
<PAGE>   9

        Before any meeting of shareholders, the board of directors may appoint
an inspector or inspectors of election to act at the meeting or its adjournment.
If no inspector of election is so appointed, then the chairman of the meeting
may, and on the request of any shareholder or a shareholder's proxy shall,
appoint an inspector or inspectors of election to act at the meeting. The number
of inspectors shall be either one (1) or three (3). If inspectors are appointed
at a meeting pursuant to the request of one (1) or more shareholders or proxies,
then the holders of a majority of shares or their proxies present at the meeting
shall determine whether one (1) or three (3) inspectors are to be appointed. If
any person appointed as inspector fails to appear or fails or refuses to act,
then the chairman of the meeting may, and upon the request of any shareholder or
a shareholder's proxy shall, appoint a person to fill that vacancy.

        Such inspectors shall:

               (a) determine the number of shares outstanding and the voting
power of each, the number of shares represented at the meeting, the existence of
a quorum, and the authenticity, validity, and effect of proxies;

               (b) receive votes, ballots or consents;

               (c) hear and determine all challenges and questions in any way
arising in connection with the right to vote;

               (d) count and tabulate all votes or consents;

               (e) determine when the polls shall close;

               (f) determine the result; and

               (g) do any other acts that may be proper to conduct the election
or vote with fairness to all shareholders.


                                   ARTICLE III

                                    DIRECTORS

        3.1    POWERS

        Subject to the provisions of the Code and any limitations in the
articles of incorporation and these bylaws relating to action required to be
approved by the shareholders or by the outstanding



                                      -9-
<PAGE>   10

shares, 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.

        3.2    NUMBER OF DIRECTORS

        The number of directors of the corporation shall be not less than two
(2) nor more than three (3). The exact number of directors shall be two (2)
until changed, within the limits specified above, by a bylaw amending this
Section 3.2, duly adopted by the board of directors or by the shareholders. The
indefinite number of directors may be changed, or a definite number may be fixed
without provision for an indefinite number, by a duly adopted amendment to the
articles of incorporation or by an amendment to this bylaw duly adopted by the
vote or written consent of holders of a majority of the outstanding shares
entitled to vote; provided, however, that if the authorized number of directors
is five (5) or more, an amendment reducing the fixed number or the minimum
number of directors to a number less than five (5) cannot be adopted if the
votes cast against its adoption at a meeting, or the shares not consenting in
the case of an action by written consent, are equal to more than sixteen and
two-thirds percent (16-2/3%) of the outstanding shares entitled to vote thereon.
No amendment may change the stated maximum number of authorized directors to a
number greater than two (2) times the stated minimum number of directors minus
one (1).

        No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.

        3.3    ELECTION AND TERM OF OFFICE OF DIRECTORS

        Directors shall be elected at each annual meeting of shareholders to
hold office until the next annual meeting. Each director, including a director
elected to fill a vacancy, shall hold office until the expiration of the term
for which elected and until a successor has been elected and qualified.

        3.4    RESIGNATION AND VACANCIES

        Any director may resign effective on giving written notice to the
chairman of the board, the president, the secretary or the board of directors,
unless the notice specifies a later time for that resignation to become
effective. If the resignation of a director is effective at a future time, the
board of directors may



                                      -10-
<PAGE>   11

elect a successor to take office when the resignation becomes effective.

        Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote or
written consent of the shareholders or by court order may be filled only by the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present (which shares voting affirmatively
also constitute a majority of the required quorum), or by the unanimous written
consent of all shares entitled to vote thereon. Each director so elected shall
hold office until the next annual meeting of the shareholders and until a
successor has been elected and qualified.

        A vacancy or vacancies in the board of directors shall be deemed to
exist (i) in the event of the death, resignation or removal of any director,
(ii) if the board of directors by resolution declares vacant the office of a
director who has been declared of unsound mind by an order of court or convicted
of a felony, (iii) if the authorized number of directors is increased, or (iv)
if the shareholders fail, at any meeting of shareholders at which any director
or directors are elected, to elect the number of directors to be elected at that
meeting.

        The shareholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election
other than to fill a vacancy created by removal, if by written consent, shall
require the consent of the holders of a majority of the outstanding shares
entitled to vote thereon.

        3.5    PLACE OF MEETINGS; MEETINGS BY TELEPHONE

        Regular meetings of the board of directors may be held at any place
within or outside the State of California that has been designated from time to
time by resolution of the board. In the absence of such a designation, regular
meetings shall be held at the principal executive office of the corporation.
Special meetings of the board may be held at any place within or outside the
State of California that has been designated in the notice of the meeting or, if
not stated in the notice or if there is no notice, at the principal executive
office of the corporation.

        Any meeting, regular or special, may be held by conference telephone or
similar communication equipment, so long as all directors participating in the
meeting can hear one another; and



                                      -11-
<PAGE>   12

all such directors shall be deemed to be present in person at the meeting.

        3.6    REGULAR MEETINGS

        Regular meetings of the board of directors may be held without notice if
the times of such meetings are fixed by the board of directors.

        3.7    SPECIAL MEETINGS; NOTICE

        Special meetings of the board of directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two directors.

        Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally or by
telephone or telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director. The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

        3.8    QUORUM

        A majority of the authorized number of directors shall constitute a
quorum for the transaction of business, except to adjourn as provided in Section
3.10 of these bylaws. Every act or decision done or made by a majority of the
directors present at a duly held meeting at which a quorum is present shall be
regarded as the act of the board of directors, subject to the provisions of
Section 310 of the Code (as to approval of contracts or transactions in which a
director has a direct or indirect material financial interest), Section 311 of
the Code (as to appointment of committees), Section 317(e) of the Code (as to
indemnification of directors), the articles of incorporation, and other
applicable law.



                                      -12-
<PAGE>   13

        A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent member at any meeting of the committee.

the board, except with respect to:

               (a) the approval of any action which, under the Code, also

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 VI, a
"director" or "officer" of the corporation includes any person (i) who is or was
a director or officer of the corporation, (ii) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was a
director or officer of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

        6.2    INDEMNIFICATION OF OTHERS

        The corporation shall have the power, to the extent and in the manner
permitted by the Code, to indemnify each of its employees and agents (other than
directors and officers) 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 VI, an "employee" or "agent" of the
corporation (other than a director or officer) 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 a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

        6.3    PAYMENT OF EXPENSES IN ADVANCE

        Expenses incurred in defending any civil or criminal action



                                      -19-
<PAGE>   20

or proceeding for which indemnification is required pursuant to Section 6.1 or
for which indemnification is permitted pursuant to Section 6.2 following
authorization thereof by the Board of Directors shall 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 VI.

        6.4    INDEMNITY NOT EXCLUSIVE

        The indemnification provided by this Article VI 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.

        6.5    INSURANCE INDEMNIFICATION

        The corporation shall have the power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or 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 VI.

        6.6    CONFLICTS

        No indemnification or advance shall be made under this Article VI,
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.

        A shareholder or shareholders of the corporation who holds at least five

agent of the corporation, on written demand and on the tender of such transfer
agent's usual charges for such list, a list of the names and addresses of the
shareholders who are entitled to vote for the election of directors, and their
shareholdings, as of the most recent record date for which that list has been
compiled or as of a date specified by the shareholder after the date of demand.
Such list shall be made available to any such shareholder by the transfer agent
on or before the later of five (5) days after the demand is received or five (5)
days after the date specified in the demand as the date as of which the list is
to be compiled.

        The record of shareholders shall also be open to inspection on the
written demand of any shareholder or holder of a voting trust certificate, at
any time during usual business hours, for a purpose reasonably related to the
holder's interests as a shareholder or as the holder of a voting trust
certificate.

        Any inspection and copying under this Section 7.1 may be made in person
or by an agent or attorney of the shareholder or holder of a voting trust

copy of these bylaws as amended to date, which bylaws shall be open to
inspection by the shareholders at all reasonable times during office hours. If
the principal executive office of the corporation is outside the State of

then the secretary shall, upon the written request of any shareholder, furnish
to that shareholder a copy of these bylaws as amended to date.

        7.3    MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS

        The accounting books and records and the minutes of proceedings of the
shareholders, of the board of directors, and of any committee or committees of
the board of directors shall be kept at such place or places as are designated
by the board of directors or, in absence of such designation, at the principal
executive office of the corporation. The minutes shall be kept in written form,
and the accounting books and records shall be kept either in written form or in
any other form capable of being converted into written form.

        The minutes and accounting books and records shall be open to inspection
upon the written demand of any shareholder or holder of a voting trust
certificate, at any reasonable time during usual business hours, for a purpose
reasonably related to the holder's interests as a shareholder or as the holder
of a voting trust certificate. The inspection may be made in person or by an
agent or attorney and shall include the right to copy and make extracts. Such
rights of inspection shall extend to the records of each subsidiary corporation
of the corporation.

        7.4    INSPECTION BY DIRECTORS

        Every director shall have the absolute right at any reasonable time to
inspect all books, records, and documents of every kind as well as the physical

        The annual report shall contain (i) a balance sheet as of the end of the

if there is no such report, the certificate of an authorized officer of the
corporation that the statements were prepared without audit from the books and
records of the corporation.

        The foregoing requirement of an annual report shall be waived so long as
the shares of the corporation are held by fewer than one hundred (100) holders
of record.

        7.6    FINANCIAL STATEMENTS

        If no annual report for the fiscal year has been sent to shareholders,
then the corporation shall, upon the written request of any shareholder made
more than one hundred twenty (120) days after the close of such fiscal year,
deliver or mail to the person making the request, within thirty (30) days
thereafter, a copy of a balance sheet as of the end of such fiscal year and an
income statement and statement of changes in financial position for such fiscal
year.

        If a shareholder or shareholders holding at least five percent (5%) of
the outstanding shares of any class of stock of the corporation makes a written
request to the corporation for an income statement of the corporation for the
three-month, six-month or nine-month period of the then current fiscal year
ended more than thirty (30) days before the date of the request, and for a
balance sheet of the corporation as of the end of that period, then the chief
financial officer shall cause that statement to be prepared, if not already
prepared, and shall deliver personally or mail that statement or statements to
the person making the request within thirty (30) days after the receipt of the
request. If the corporation has not sent to the shareholders its annual report
for the last fiscal year, the statements referred to in the first paragraph of
this Section 7.6 shall likewise be delivered or mailed to the shareholder or
shareholders within thirty (30) days after the request.

        The quarterly income statements and balance sheets referred to in this
section shall be accompanied by the report, if any, of any



                                      -23-

independent accountants engaged by the corporation or by the certificate of an
authorized officer of the corporation that the financial statements were
prepared without audit from the books and records of the corporation.

        The chairman of the board, the president, any vice president, the chief
financial officer, the secretary or assistant secretary of this corporation, or

                                  ARTICLE VIII

                                 GENERAL MATTERS

        8.1    RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

        For purposes of determining the shareholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect of any other lawful
action (other than action by shareholders by written consent without a meeting),
the board of directors may fix, in advance, a record date, which shall not be
more than sixty (60) days before any such action. In that case, only
shareholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided in the Code.

        If the board of directors does not so fix a record date, then the record
date for determining shareholders for any such purpose shall be at the close of
business on the day on which the board adopts the applicable resolution or the
sixtieth (60th) day before the date of that action, whichever is later.

        8.2    CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS



                                      -24-

        From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

        8.3    CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED

        The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

        8.4    CERTIFICATES FOR SHARES

        A certificate or certificates for shares of the corporation shall be
issued to each shareholder when any of such shares are fully paid. The board of
directors may authorize the issuance of certificates for shares partly paid
provided that these certificates shall state the total amount of the
consideration to be paid for them and the amount actually paid. All certificates
shall be signed in the name of the corporation by the chairman of the board or
the vice chairman of the board or the president or a vice president and by the
chief financial officer or an assistant treasurer or the secretary or an
assistant secretary, certifying the number of shares and the class or series of
shares owned by the shareholder. Any or all of the signatures on the certificate
may be facsimile.

        In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed on a certificate ceases to be that officer,
transfer agent or registrar before that certificate is issued, it may be issued
by the corporation with the same effect as if that person were an officer,
transfer agent or registrar at the date of issue.

        8.5    LOST CERTIFICATES

        Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and can-

celled at the same time. The board of directors may, in case any share
certificate or certificate for any other security is lost, stolen or destroyed,
authorize the issuance of replacement certificates on such terms and conditions
as the board may require; the board may require indemnification of the
corporation secured by a bond or other adequate security sufficient to protect
the corporation against any claim that may be made against it, including any
expense or liability, on account of the alleged loss, theft or destruction of
the certificate or the issuance of the replacement certificate.

        8.6    CONSTRUCTION; DEFINITIONS

        Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Code shall govern the construction of these
bylaws. Without limiting the generality of this provision, the singular number
includes the plural, the plural number includes the singular, and the term
"person" includes both a corporation and a natural person.

                                   AMENDMENTS

        9.1    AMENDMENT BY SHAREHOLDERS

        New bylaws may be adopted or these bylaws may be amended or repealed by
the vote or written consent of holders of a majority of the outstanding shares
entitled to vote; provided, however, that if the articles of incorporation of
the corporation set forth the number of authorized directors of the corporation,
then the authorized number of directors may be changed only by an amendment of
the articles of incorporation.

        9.2    AMENDMENT BY DIRECTORS

        Subject to the rights of the shareholders as provided in Section 9.1 of
these bylaws, bylaws, other than a bylaw or an amendment of a bylaw changing the
authorized number of directors (except to fix the authorized number of directors
pursuant to a bylaw providing for a variable number of directors), may be
adopted, amended or repealed by the board of directors.

                          AMENDMENTS TO PIXAR'S BYLAWS


        Effective upon this corporation's becoming a "listed corporation" within
the meaning of Section 301.5 of the California Corporations Code, Section 2.8 of
the Bylaws of this corporation shall be amended in its entirety to read as
follows:

        "2.8   VOTING

        The shareholders entitled to vote at any meeting of shareholders shall
be determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 702 through 704 of the Code (relating to
voting shares held by a fiduciary, in the name of a corporation or in joint
ownership).

        The shareholders' vote may be by voice vote or by ballot; provided,
however, that any election for directors must be by ballot if demanded by any
shareholder at the meeting and before the voting has begun.

        Except as provided in the articles of incorporation, each outstanding
share, regardless of class, shall be entitled to one vote on each matter
submitted to a vote of the shareholders. Any share holder entitled to vote on
any matter may vote part of the shares in favor of the proposal and refrain from
voting the remaining shares or, except when the matter is the election of
directors, may vote them against the proposal; but, if the shareholder fails to
specify the number of shares which the shareholder is voting affirmatively, it
will be conclusively presumed that the shareholder's approving vote is with
respect to all shares which the shareholder is entitled to vote.

        If a quorum is present, the affirmative vote of the majority of the
shares represented and voting at a duly held meeting (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or a vote by
classes is required by the Code or by the articles of incorporation."

        No shareholder entitled to vote at any election of directors shall be
entitled to cumulate votes for candidates in nomination either (i) by giving 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
normally entitled or (ii) by distributing the shareholder's votes on the same
principle among any or all of the candidates, as the shareholder thinks fit.
This paragraph shall become effective only when the corporation becomes a
"listed corporation" within the meaning of Section 301.5 of the California
Corporations Code. This paragraph may not be modified, amended, rescinded or
repealed except by a duly adopted amendment to the articles of incorporation or
by an amendment to this bylaw duly adopted by the vote or written consent of the
holders of a majority of the outstanding shares entitled to vote."
