within and without the State of California as the Board may from time to time
determine or the business of the Corporation may require.

                                   ARTICLE II
                            MEETINGS OF SHAREHOLDERS

     2.01. Meetings of Shareholders of the Corporation (the "Shareholders") for
any purpose may be held at such place, within or without the State of
California, as shall be fixed from time to time by the Board, or, if the Board
has not so specified, then at such place as may be fixed by the person or
persons calling the meeting.

     2.02. An annual meeting of the Shareholders shall be held at such date and
time as shall be fixed from time to time by the Board, at which they shall elect
a Board, and transact such other business as may properly be brought before the
meeting.

     2.03. At least ten days before each meeting of Shareholders, a complete
list of the Shareholders entitled to vote at said meeting arranged in
alphabetical order, with the residence of each and the number of voting shares
held by each, shall be prepared by the officer or agent having charge of the
stock transfer books. Such list, for a period of ten days prior to such meeting,
shall be kept on file at the registered office of the Corporation and shall be
subject to inspection by any Shareholder at any time during usual business
hours. Such list shall be produced and kept open at the time and place of the
meeting during the whole time thereof, and shall be subject to the inspection of
any Shareholder who may be present.

     2.04. Special meetings of the Shareholders, for any purpose or purposes,
unless otherwise prescribed by statute, the Charter, or these bylaws, may be
called by the President, a majority of the Board, or the holders of not less

transacted at all special meetings shall be confined to the objects stated in
the notice of the meeting.

outstanding and entitled to vote thereat, present in person or represented by
proxy, shall be requisite and shall constitute a quorum at all meetings of the
Shareholders for the transaction of business except as otherwise provided by
statute, the Charter, or these bylaws. If, however, such quorum shall not be
present or represented at any meeting of the Shareholders, the Shareholders
entitled to vote thereat, present in person or represented by proxy, shall
nevertheless have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall be present or
represented. At an adjourned session at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified.

     2.07. When a quorum is present at any meeting, the vote of the holders of a
majority of the shares of the Corporation having voting power present in person
or represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which, by express provision of any applicable
statute, the Charter, or these bylaws, a different vote is required, in which
case such express provision shall govern and control the decision of such
question. The Shareholders present at a duly organized meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
Shareholders to leave less than a quorum.

     2.08. Each outstanding share of the Corporation, regardless of class, shall
be entitled to one vote on each matter submitted to a vote at a meeting of
Shareholders, unless otherwise provided by statute or the Charter. At any
meeting of the Shareholders, every Shareholder having the right to vote shall be
entitled to vote in person or by proxy appointed by an instrument in writing
subscribed by such Shareholder or by his or her duly authorized
attorney-in-fact, such writing bearing a date not more than eleven months prior
to said meeting, unless said instrument provides for a longer period. Such proxy

determining Shareholders entitled to notice of or to vote at a meeting of
Shareholders, such record date to be not less than ten nor more than sixty days
prior to such meeting, or the Board may close the stock transfer books for such
purpose for a period of not less than ten nor more than sixty days prior to such
meeting. In the absence of any action by the Board, the date upon which the
notice of the meeting is mailed shall be the record date.

     2.10. Any action required by statute to be taken at a meeting of the
Shareholders, or any action which may be taken at a meeting of the Shareholders,
may be taken without a meeting if a consent in writing, setting forth the action
so taken, shall be signed by all of the Shareholders entitled to vote with
respect to the subject matter thereof, and such consent shall have the same
force and effect as a unanimous vote of Shareholders.

     2.11. Subject to the provisions required or permitted by statute or the
Charter for notice of meetings, Shareholders may participate in and hold a
meeting by means of conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other, and

person at such meeting, except where a person participates in the meeting for
the express purpose of objecting to the transaction of any business on the
ground that the meeting is not lawfully called or convened.

     3.01. The business and affairs of the Corporation shall be managed by the

acts and things as are not by statute or by the Charter or by these bylaws
directed or required to be exercised or done by the Shareholders.

number of directors which shall constitute the full Board shall be as determined
from time to time by resolution of the Board or by the Shareholders at the
annual meeting or a special meeting called for that purpose, but no decrease
shall have the effect of shortening the term of an incumbent director. Directors
need not be Shareholders or residents of the State of California. The directors
shall be elected at the annual meeting of the Shareholders, except as
hereinafter provided, and each director elected shall hold office until his or
her successor shall be elected and shall qualify.

     3.03. At any meeting of Shareholders called expressly for such purpose, any
director or the entire Board may be removed, with or without cause, by vote of
the holders of a majority of the shares of the Corporation then entitled to vote
at an election of directors. If any vacancies occur in the Board caused by
death, resignation, retirement, disqualification, or removal from office of any
director or otherwise, a majority of the directors then in office, though less
than a quorum, may choose a successor or successors or a successor or successors
may be chosen at a special meeting of Shareholders called for that purpose; and
each successor director so chosen shall be elected for the unexpired term of his
or her predecessor in office. Any directorship to be filled by reason of an
increase in the number of directors may be filled by election at an annual
meeting or special meeting of Shareholders called for that purpose or may be
filled by the Board for a term of office continuing only until the next election
of one or more directors by the Shareholders.

     3.04. Whenever the holders of any class or series of shares of the
Corporation are entitled to elect one or more directors by the provisions of the
Charter, any vacancies in such directorships and any newly created directorships
of such class or series to be filled by reason of an increase in the number of
such directors may be filled by the affirmative vote of a majority of the
directors elected by such class or series then in office or by a sole remaining
director so elected, or by the vote of the holders of the outstanding shares of
such class or series, and such directorships shall not in any case be filled by
the vote of the remaining directors or the holders of the outstanding shares as
a whole unless otherwise provided in the Charter.


                                       3



     3.05. At each election for directors, every Shareholder entitled to vote at
such election shall have the right to vote, in person or by proxy, the number of
shares owned by such Shareholder for as many persons as there are directors to
be elected and for whose election he has a right to vote, or to cumulate his
votes by giving one candidate as many votes as the number of such directors
multiplied by his shares shall equal, or by distributing such votes on the same
principle.

                         Executive and Other Committees

     3.06. The Board, by resolution adopted by a majority of the Board, may
designate from among its members an executive committee and one or more other

authority of the Board, including the authority to declare dividends and to
authorize the issuance of shares of the Corporation, to the extent permitted by
law. Committees shall keep regular minutes of their proceedings and report the
same to the Board when required.

regular and special, either within or without the State of California.

     3.08. The first meeting of each newly elected Board shall be held without
further notice immediately following the annual meeting of Shareholders, and at
the same place, unless by unanimous consent of the directors then elected and
serving such time or place shall be changed.

     3.09. Regular meetings of the Board may be held without notice at such time
and place as shall from time to time be determined by the Board.

     3.10. Special meetings of the Board may be called by the President on two
days' notice to each director, either personally or by mail, telecopy, or
overnight courier; special meetings shall be called by the President or
Secretary in like manner and on like notice on the written request of a majority
of the directors. Except as may be otherwise expressly provided by statute, the
Charter, or these bylaws, neither the business to be transacted at, nor the
purpose of, any special meeting needs to be specified in a notice or waiver of
notice.

     3.11. At all meetings of the Board the presence of a majority of the full
Board shall be necessary and sufficient to constitute a quorum for the
transaction of business and the act of a majority of the directors present at
any meeting at which there is a quorum shall be the act of the Board, except as
may be otherwise specifically provided by statute or by the Charter or by these
bylaws. If a quorum shall not be present at any meeting of directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

     3.12. Any action required or permitted to be taken at a meeting of the
Board or any committee may be taken without a meeting if a consent in writing,
setting forth the action so taken, is signed by all the members of the Board or

as a unanimous vote at a meeting.

Charter for notice of meetings, members of the Board, or members of any
committee designated by the Board, may participate in and hold a meeting of the
Board or such committee by means of a conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
section shall constitute presence in person at such meeting, except where a
person participates in the meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting is not lawfully
called or convened.

                            Compensation of Directors

     3.14. Directors, as such, shall not receive any stated salary for their
services, but, by resolution of the Board, a fixed sum and expenses of
attendance, if any, may be allowed for attendance at each regular or special
meeting of the Board; provided that nothing herein contained shall be construed
to preclude any director from serving the Corporation in any other capacity and
receiving compensation therefor.

director of the Corporation under the provisions of any applicable statute, the
Charter or these bylaws, a waiver thereof in writing signed by the person or
persons entitled to such notice, whether before or after the time stated in such
notice, shall be deemed equivalent to the giving of such notice.

precedent to the issuance thereof, may require the owner of such lost or
destroyed certificate, or his legal representative, to advertise the same in
such manner as it shall require and/or give the Corporation a bond in such form,
in such sum, and with such surety or sureties as it may direct as indemnity
against any claim that may be made against the Corporation with respect to the

Corporation may hold securities and to execute and deliver in the name and on
behalf of the Corporation any written consent of security holders in lieu of any
such meeting, and at any such meeting he, or the agent or the attorney-in-fact
duly authorized by him, shall possess and may exercise any and all rights and
powers incident to the ownership of such securities which the Corporation as the
owner thereof might have possessed or exercised if present. The Board may by
resolution from time to time confer like power upon any other person or persons.

                                 Indemnification

     7.07. (a) Subject to any limitation which may be contained in the Charter,
the Corporation shall to the full extent permitted by law, indemnify any person
who was, is, or is threatened to be made a named defendant or respondent to any
threatened, pending, or completed action, suit, or proceeding, whether civil,
criminal, arbitral, administrative, or investigative, any appeal in such action,
suit, or proceeding, and any inquiry or investigation that could lead to such an
action, suit, or proceeding, because such person is or was a director or officer
of the Corporation, or is or was serving at the request of the Corporation as a
director, officer, partner, venturer, proprietor, trustee, employee, agent, or
similar functionary of another corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan, or other enterprise, against
judgments, penalties (including excise and similar taxes), fines, settlements,
and reasonable expenses (including attorneys' fees) actually incurred by such
person in connection with such action, suit, or proceeding. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that an individual did not act in good faith and in a manner which
he reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     (b) Subject to any limitation which may be contained in the Charter, the
Corporation shall, to the full extent permitted by law, pay or reimburse on a
current basis the expenses incurred by any person described in subsection (a) of
this Section 7.07 in connection with any such action, suit, or proceeding in
advance of the final disposition thereof, if the Corporation has received (i) a
written affirmation by the recipient of his good faith belief that he has met
the standard of conduct necessary for indemnification and (ii) a written
undertaking by or on behalf


                                       10



of the director to repay the amount paid or reimbursed if it is ultimately
determined that he has not satisfied such standard of conduct or if
indemnification is prohibited by law.

     (c) If required by law at the time such payment is made, any payment of
indemnification or advance of expenses to a director shall be reported in
writing to the shareholders with or before the notice or waiver of notice of the
next Shareholder's meeting or with or before the next submission to Shareholders
of a consent to action without a meeting, within the 12-month period immediately
following the date of the indemnification or advance.

     (d) The Corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Corporation
or who is or was serving at the request of the Corporation as a director,
officer, partner, venturer, proprietor, trustee, employee, agent, or similar
functionary of another foreign or domestic corporation, partnership, joint
venture, sole proprietorship, trust, employee benefit plan, or other enterprise,
against any liability asserted against him and incurred by him in such a
capacity or arising out of his status as such a person, whether or not the
corporation would have the power to indemnify him against that liability under
this article, subject to any restrictions imposed by law. The Corporation may
create a trust fund, establish any form of self-insurance, grant a security
interest or other lien on the assets of the Corporation, or use other means
(including, without limitation, a letter of credit, guarantee or surety
arrangement) to ensure the payment of such sums as may become necessary to
effect indemnification as provided herein.

     (e) The rights provided under this Section 7.07 shall not be deemed
exclusive of any other rights permitted by law to which such person may be
entitled under any provision of the Charter, a resolution of Shareholders or
directors of the Corporation, an agreement or otherwise, and shall continue as
to a person who has ceased to be a director, officer, employee, or agent and
shall inure to the benefit of the heirs, executors, and administrators of such a
person. The rights provided in this Section 7.07 shall be deemed to be provided
by a contract between the Corporation and the individuals who serve in the
capacities described in subsection (a) hereof at any time while these bylaws are
in effect, and no repeal or modification of this Section 7.07 by the
Shareholders shall adversely affect any right of any person otherwise entitled
to indemnification by virtue of this Section 7.07 at the time of such repeal or
modification.

                                  ARTICLE VIII

                                   AMENDMENTS

     8.01. The Board may amend or repeal these bylaws or adopt new bylaws,
unless:

     (1) the Charter or statute reserves the power exclusively to the
Shareholders in whole or part; or

     (2) the Shareholders in amending, repealing or adopting a particular bylaw
expressly provide that the Board may not amend or repeal such bylaw.

     8.02. Unless the Charter or a bylaw adopted by the Shareholders provides
otherwise as to all or some portion of the Corporation's bylaws, the
Shareholders may amend, repeal, or adopt


                                       11



bylaws of the Corporation even though such bylaws may also be amended, repealed
or adopted by the Board.

                            A California Corporation

                                    ARTICLE I
                              DIRECTORS; MANAGEMENT

Section 1. a. Powers.

     Subject to the provisions of the General Corporation Law of California,
effective January 1, 1977 (to which the various Section numbers quoted herein
relate) and subject to any limitation in the Articles of Incorporation and the
By-Laws relating to action required to be approved by the Shareholders (Sec.
153) or by the outstanding shares (Sec. 152), the business and affairs of this
corporation shall be managed by and all corporate powers shall be exercised by
or under direction of the Board of Directors.

     b.   Standard of Care.

     Each Director shall exercise such powers and otherwise perform such duties
in good faith, in the manner such Director believes to be in the best interests
of the corporation, and with such care, including reasonable inquiry, using
ordinary prudence, as a person in a like position would use under similar
circumstances. (Sec. 309)

     c.   Exception for Close Corporation.

     Notwithstanding the provisions of Section 1, in the event that this
corporation shall elect to become a close corporation as defined in Sec. 158,
its Shareholders may enter into a Shareholders' Agreement as provided in Sec.
300 (b). Said agreement may provide for the exercise of corporate powers and the
management of the business and affairs of this corporation by the Shareholders,
provided however such agreement shall, to the extent and so long as the
discretion or the powers of the Board in its management of corporate affairs is
controlled by such agreement, impose upon each Shareholder who is a party
thereof, liability for managerial acts performed or omitted by such person
pursuant thereto otherwise imposed upon Directors as provided in Sec. 300(d).

Section 2. Number and Qualification.

     The authorized number of Directors of the corporation shall be ONE (1).

     This number may be changed by amendment to the Articles of Incorporation or

     Vacancies in the Board of Directors 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 meeting of Shareholders or at a special meeting called for that
purpose.

     The Shareholders may at any time elect a Director to fill any vacancy not
filled by the Directors, and may elect the additional Directors at the meeting
at which an amendment of the By-Laws is voted authorizing an increase in the
number of Directors.

     A vacancy or vacancies shall be deemed to exist in case of the death,
resignation or removal of any Director, or if the Shareholders shall increase
the authorized number of Directors but shall fail at the meeting at which such
increase is authorized, or at an adjournment thereof, to elect the additional
Director so provided for, or in case the Shareholders fail at any time to elect
the full number of authorized Directors.

     If the Board of Directors accepts the resignation of a Director tendered to
take effect at a future time, the Board, or the Shareholders, shall have power
to elect a successor to take office when the resignation shall become effective.

     No reduction of the number of Directors shall have the effect of removing
any Director prior to the expiration of his term of office.

Section 5. Removal of Directors.

     The entire Board of Directors or any individual Director may be removed
from office as provided by Secs. 302, 303 and 304 of the Corporations Code of
the State of California. In such case, the remaining Board members may elect a
successor Director to fill such vacancy for the remaining unexpired term of the
Director so removed.

Section 6. Notice, Place and Manner of Meetings.

     Meetings of the Board of Directors may be called by the Chairman of the
Board, or the President, or any Vice President, or the Secretary, or any two (2)

may participate in a meeting through use of a conference telephone or similar

     At least forty-eight (48) hours notice of the time and place of special
meetings shall be delivered personally to the Directors or personally
communicated to them by a corporate Officer by telephone or telegraph. If the
notice is sent to a Director by letter, it shall be 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 is not readily ascertainable, at the place in which the
meetings of the Directors are regularly held). In case such notice is mailed, it
shall be deposited in the United States mail, postage prepaid, in the place in
which the principal executive office of the corporation is located at least four
(4) days prior to the time of the holding of the meeting. Such mailing,
telegraphing, telephoning or delivery as above provided shall be due, legal and
personal notice to such Director.

Section 9. Waivers.

     When (i) all of the Directors are present at any organizational, regular or
special meeting, however called or noticed, and sign a written consent thereto
on the records of such meeting, or, (ii) if a majority of the Directors are
present and if those not present sign a waiver of notice of such meeting or a
consent to holding the meeting or an approval of the minutes thereof, whether
prior to or after the holding of such meeting, which said waiver, consent or
approval shall be filed with the corporate records or made a part of the minutes
of the meeting or (iii) if a Director attends a meeting without notice but
without protesting, prior thereto or at its commencement, the lack of notice to
him, then the transactions thereof are as valid as if had at a meeting regularly
called and noticed.


                                       18



Section 10. Sole Director Provided by Articles of Incorporation.

     In the event only one Director is required by the By-Laws or Articles of
Incorporation, then any reference herein to notices, waivers, consents, meetings
or other actions by a majority or quorum of the Directors shall be deemed to
refer to such notice, waiver, etc., by such sole Director, who shall have all
the rights and duties and shall be entitled to exercise all of the powers and
shall assume all the responsibilities otherwise herein described as given to a
Board of Directors.

Section 11. Directors Acting by Unanimous Written Consent.

     Any action required or permitted to be taken by the Board of Directors may
be taken without a meeting and with the same force and effect as if taken by a
unanimous vote of Directors, if authorized by a writing signed individually or
collectively by all members of the Board. Such consent shall be filed with the
regular minutes of the Board.

Section 12. Quorum.

     A majority of the number of Directors as fixed by the Articles of
Incorporation or By-Laws shall be necessary to constitute a quorum for the
transaction of business, and the action of a majority of the Directors present
at any meeting at which there is a quorum, when duly assembled, is valid as a
corporate act; provided that a minority of the Directors, in the absence of a
quorum, may adjourn from time to time, but may not transact any business. A

     The transactions of any meeting of Shareholders, however called and
noticed, shall be 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 Shareholders entitled to vote, not
present in person or by proxy, sign a written waiver of notice, or a consent to
the holding of 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. Attendance shall constitute a waiver of
notice, unless objection shall be made as provided in Sec. 601(e).

Section 6. Shareholders Acting Without A Meeting - Directors.

     Any action which may be taken at a meeting of the Shareholders may be taken
without a meeting or notice of meeting if authorized by a writing signed by all
of the Shareholders entitled to vote at a meeting for such purpose and filed
with the Secretary of the corporation, provided further that while ordinarily
Directors can only be elected by unanimous written consent under Sec. 603(d), as
to vacancy created by death, resignation or other causes, if the Directors fail
to fill a vacancy, then a Director to fill that vacancy may be elected by the
written consent of persons holding a majority of shares entitled to vote for the
election of Directors.

Section 7. Other Actions Without A Meeting.

     Unless otherwise provided in the GCL or the Articles, 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, shall be signed by the holders of outstanding shares having not
less than the minimum number of votes that would be necessary to authorize or
take such action at a meeting at which all shares entitled to vote thereon were
present and voted.

     Unless the consents of all Shareholders entitled to vote have been
solicited in writing,

          (1) Notice of any Shareholder approval pursuant to Secs. 310, 317,
     1201 or 2007 without a meeting by less than unanimous written consent shall
     be given at least 10 days before the consummation of the action authorized
     by such approval, and

          (2) Prompt notice shall be given of the taking of any other corporate
     action approved by Shareholders without a meeting by less than unanimous
     written consent, to each of those Shareholders entitled to vote who have
     not consented in writing.

     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 their respective proxyholders, may revoke the consent by a
writing received by the corporation prior to the time


                                       24



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 is effective upon its receipt by the Secretary.

Section 8. Quorum.

     The holders of a majority of the shares entitled to vote thereat, present
in person, or represented by proxy, shall constitute a quorum at all meetings of
the Shareholders for the transaction of business except as otherwise provided by
law, by the Articles of Incorporation, or by these By-Laws. If, however, such
majority shall not be present or represented at any meeting of the Shareholders,
the Shareholders entitled to vote thereat, present in person, or by proxy, shall
have the power to adjourn the meeting from time to time, until the requisite
amount of voting shares shall be present. At such adjourned meeting at which the
requisite amount of voting shares shall be represented, any business may be
transacted which might have been transacted at a meeting as originally notified.

     If a quorum be initially present, the Shareholders may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
Shareholders to leave less than a quorum, if any action taken is approved by a
majority of the Shareholders required to initially constitute a quorum.

Section 9. Voting Rights; Cumulative Voting.

     Only persons in whose names shares entitled to vote stand on the stock
records of the corporation on the day of any meeting of Shareholders, unless
some other day be fixed by the Board of Directors for the determination of
Shareholders of record, and then on such other day, shall be entitled to vote at
such meeting.

     Provided the candidate's name has been placed in nomination prior to the
voting and one or more Shareholders has given notice at the meeting prior to the
voting of the Shareholder's intent to cumulate the Shareholder's votes, every
Shareholder entitled to vote at any election for Directors of any corporation
for profit may cumulate his votes 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 his shares are entitled, or distribute his votes on the same principle
among as many candidates as he thinks fit.

     The candidates receiving the highest number of votes up to the number of
Directors to be elected are elected.

     The Board of Directors may fix a time in the future not exceeding sixty
days preceding the date of any meeting of Shareholders or the date fixed for the
payment of any dividend or distribution, or for the allotment of rights, or when
any change or conversion or exchange of shares shall go into effect, as a record
date for the determination of the Shareholders entitled to notice of and to vote
at any such meeting, or entitled to receive any such dividend or distribution,
or any allotment of rights, or to exercise the rights in respect to any such
change, conversion or exchange of shares. In such case only Shareholders of
record on the date so fixed shall be entitled to notice of and to vote at such
meeting, or to receive such dividends, distribution or allotment of rights, or
to exercise such rights, as the case may be, notwithstanding any transfer of


                                       25



any share on the books of the company after any record date fixed as aforesaid.
The Board of Directors may close the books of the company against transfers of
shares during the whole or any part of such period.

Section 10. Proxies.

     Every Shareholder entitled to vote, or to execute consents, may do so,
either in person or by written proxy, executed in accordance with the provisions
of Secs. 604 and 705 of the Code and filed with the Secretary of the
corporation.

Section 11. Organization.

     The President, or in the absence of the President, any Vice President,
shall call the meeting of the Shareholders to order, and shall act as chairman
of the meeting. In the absence of the President and all of the Vice Presidents,
Shareholders shall appoint a chairman for such meeting. The Secretary of the
company shall act as Secretary of all meetings of the Shareholders, but in the
absence of the Secretary at any meeting of the Shareholders, the presiding
Officer may appoint any person to act as Secretary of the meeting.

Section 12. Inspectors of Election.

     In advance of any meeting of Shareholders the Board of Directors may, if
they so elect, appoint inspectors of election to act at such meeting or any
adjournments thereof. If inspectors of election be not so appointed, the
chairman of any such meeting may, and on the request of any Shareholder or his
proxy shall, make such appointment at the meeting in which case the number of
inspectors shall be either one or three as determined by a majority of the
Shareholders represented at the meeting.

Section 13. Shareholders' Agreements.

     Notwithstanding the above provisions in the event this corporation elects
to become a close corporation, an agreement between two or more Shareholders
thereof, if in writing and signed by the parties thereof, may provide that in
exercising any voting rights the shares held by them shall be voted as provided
therein or in Sec. 706, and may otherwise modify these provisions as to
Shareholders' meetings and actions.

     The shares of this corporation may be owned only by a medical corporation
or by a licensed physician and surgeon. Where there are two or more shareholders
of the corporation, and one of them dies, or ceases to become an eligible
shareholder, or becomes a disqualified person as defined in Section 13401(d) of
the California Corporations Code for a period exceeding 90 days, the shares of
such person in this corporation shall be sold and transferred to the
corporation, its other shareholders, or other eligible persons, on such terms as
are agreed upon. Such sale or transfer shall not be later than six (6) months
after any such death and not later than ninety (90) days after the date he

reason of the fact that he is also a director of the corporation. The income of
the corporation attributable to its practice of medicine, while a shareholder is
disqualified to hold shares of the corporation, shall not in any manner accrue
to the benefit of such shareholder or his shares except insofar as such
disqualified shareholder has a right to receive payment for his shares in
accordance with an agreement of sale.
