                                  ARTICLE III

                   SHAREHOLDERS' MEETINGS AND VOTING RIGHTS

     SECTION 4.  PLACE OF MEETINGS.  Meetings of shareholders shall be held at
the principal executive office of the corporation, or at any other place, within
or outside the State of California, which may be fixed either by the Board of
Directors or by the written consent of all persons entitled to vote at such
meeting, given either before or after the meeting and filed with the Secretary
of the Corporation.

                                      1.

 
     SECTION 5.  ANNUAL MEETINGS.  The annual meeting of the shareholders of the
corporation shall be held on any date and time which may from time to time be
designated by the Board of Directors.  At such annual meeting directors shall be
elected and any other business may be transacted which may properly come before

     SECTION 6.  POSTPONEMENT OF ANNUAL MEETING.  The Board of Directors and the
President shall each have authority to hold at an earlier date and/or time, or

     SECTION 7.  SPECIAL MEETINGS.

          (a) Special meetings of the shareholders, for any purpose or purposes,
may be called by the Board of Directors, the Chairman of the Board of Directors,

percent (10%) of the votes at the meeting.

          (b) Upon written request to the Chairman of the Board of Directors,
the President, any vice president or the Secretary of the corporation by any
person or persons (other than the Board of Directors) entitled to call a special
meeting of the shareholders, such officer forthwith shall cause notice to be
given to the shareholders entitled to vote, that a meeting will be held at a
time requested by the person or persons calling the meeting, such time to be not
less than thirty-five (35) nor more than sixty (60) days after receipt of such
request.  If such notice is not given within twenty (20) days after receipt of
such request, the person or persons calling the meeting may give notice thereof
in the manner provided by law or in these bylaws. Nothing contained in this
Section 7 shall be construed as limiting, fixing or affecting the time or date
when a meeting of shareholders called by action of the Board of Directors may be
held.

     SECTION 8.  NOTICE OF MEETINGS.  Except as otherwise may be required by law
and subject to subsection 7(b) above, written notice of each meeting of
shareholders shall be given to each shareholder entitled to vote at that meeting
(see Section 15 below), by the Secretary, assistant secretary or other person
charged with that duty, not less than ten (10) (or, if sent by third class mail,
thirty (30)) nor more than sixty (60) days before such meeting.

     Notice of any meeting of shareholders shall state the date, place and hour
of the meeting and,

          (a) in the case of a special meeting, the general nature of the
business to be transacted, and no other business may be transacted at such
meeting;

          (b) in the case of an annual meeting, the general nature of matters
which the Board of Directors, at the time the notice is given, intends to
present for action by the shareholders;

                                      2.

 
          (c) in the case of any meeting at which directors are to be elected,
the names of the nominees intended at the time of the notice to be presented by
management for election; and

          (d) in the case of any meeting, if action is to be taken on any of the
following proposals, the general nature of such proposal:

              (1) a proposal to approve a transaction within the provisions of
California Corporations Code, Section 310 (relating to certain transactions in
which a director has a direct or indirect financial interest);

              (2) a proposal to approve a transaction within the provisions of
California Corporations Code, Section 902 (relating to amending the Articles of
Incorporation of the corporation);

              (3) a proposal to approve a transaction within the provisions of
California Corporations Code, Sections 181 and 1201 (relating to
reorganization);

              (4) a proposal to approve a transaction within the provisions of
California Corporations Code, Section 1900 (winding up and dissolution);

              (5) a proposal to approve a plan of distribution within the 
provisions of California Corporations Code, Section 2007 (relating to certain
plans providing for distribution not in accordance with the liquidation rights
of preferred shares, if any).

          At a special meeting, notice of which has been given in accordance
with this Section, action may not be taken with respect to business, the general
nature of which has not been stated in such notice.  At an annual meeting,
action may be taken with respect to business stated in the notice of such
meeting, given in accordance with this Section, and, subject to subsection 8(d)
above, with respect to any other business as may properly come before the
meeting.

     SECTION 9.  MANNER OF GIVING NOTICE.  Notice of any meeting of shareholders
shall be given either personally or by first-class mail, or, if the corporation
has outstanding shares held of record by 500 or more persons (determined as
provided in California Corporations Code Section 605) on the record date for
such meeting, third-class mail, or telegraphic or other written communication,
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
first-class 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.

                                      3.

 
     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, all
future notices shall be deemed to have been duly given without further mailing
if these shall be available to the shareholder on written demand by the
shareholder at the principal executive office of the corporation for a period of
one year from the date of the giving of the notice.

     An affidavit of mailing of any notice or report in accordance with the
provisions of this Section 9, executed by the Secretary, Assistant Secretary or
any transfer agent, shall be prima facie evidence of the giving of the notice.

     SECTION 10.  QUORUM AND TRANSACTION OF BUSINESS.

          (a) At any meeting of the shareholders, a majority of the shares
entitled to vote, represented in person or by proxy, shall constitute a quorum.
If a quorum is present, the affirmative vote of the majority of 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 law or by the Articles of Incorporation, and except as provided in
subsection (b) below.

          (b) The shareholders present at a duly called or held meeting of the
shareholders 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, provided that any action taken (other than adjournment) is
approved by at least a majority of the shares required to constitute a quorum.

          (c) In the absence of a quorum, no business other than adjournment may
be transacted, except as described in subsection (b) above.

     SECTION 11.  ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS.  Any meeting
of shareholders may be adjourned from time to time, whether or not a quorum is
present, by the affirmative vote of a majority of shares represented at such
meeting either in person or by proxy and entitled to vote at such meeting.

     In the event any meeting is adjourned, it shall not be necessary to give
notice of the time and place of such adjourned meeting pursuant to Sections 8
and 9 of these bylaws; provided that if any of the following three events occur,
such notice must be given:

          (a) announcement of the adjourned meeting's time and place is not made
at the original meeting which it continues or

          (b) such meeting is adjourned for more than forty- five (45) days from
the date set for the original meeting or

          (c) a new record date is fixed for the adjourned meeting.

                                      4.

 
     At the adjourned meeting, the corporation may transact any business which
might have been transacted at the original meeting.

     SECTION 12.  WAIVER OF NOTICE, CONSENT TO MEETING OR APPROVAL OF MINUTES.

          (a) Subject to subsection (b) of this Section, the transactions of any
meeting of shareholders, however called and noticed, and wherever held, shall be
as valid as though made at a meeting duly held after regular call and notice, if
a quorum is present either in person or by proxy, and if, either before or after
the meeting, each of the persons entitled to vote but not present in person or
by proxy signs a written waiver of notice or a consent to holding of the meeting
or an approval of the minutes thereof.

          (b) A waiver of notice, consent to the holding of a meeting or
approval of the minutes thereof need not specify the business to be transacted
or transacted at nor the purpose of the meeting; provided that in the case of
proposals described in subsection (d) of Section 8 of these bylaws, the general
nature of such proposals must be described in any such waiver of notice and such
proposals can only be approved by waiver of notice, not by consent to holding of
the meeting or approval of the minutes.

          (c) All waivers, consents and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

          (d) A person's attendance at a meeting shall constitute waiver of
notice of and presence at such meeting, except when such person objects at the
beginning of the meeting to 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 which are required
by law or these bylaws to be in such notice (including those matters described
in subsection (d) of Section 8 of these bylaws), but are not so included if such
person expressly objects to consideration of such matter or matters at any time
during the meeting.

     SECTION 13.  ACTION BY WRITTEN CONSENT WITHOUT A MEETING.  Any action
which may be taken at any meeting of shareholders may be taken without a meeting
and without prior notice if written consents setting forth the action so taken
are signed by the holders of the 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.

     Directors may not be elected by written consent except by unanimous written
consent of all shares entitled to vote for the election of directors; provided
that any vacancy on the Board of Directors (other than a vacancy created by
removal) which has not been filled by the board of directors may be filled by
the written consent of a majority of outstanding shares entitled to vote for the
election of directors.

     Any written consent may be revoked pursuant to California Corporations Code
Section 603(c) prior to the time that written consents of the number of shares
required to

                                      5.

 
authorize the proposed action have been filed with the Secretary.  Such
revocation must be in writing and will be effective upon its receipt by 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 shall not have been received, the Secretary shall give prompt
notice of any corporate action approved by the shareholders without a meeting to
those shareholders entitled to vote on such matters who have not consented
thereto in writing.  This notice shall be given in the manner specified in
Section 9 of these bylaws.  In the case of approval of (i) a transaction within
the provisions of California Corporations Code, Section 310 (relating to certain
transactions in which a director has an interest), (ii) a transaction within the
provisions of California Corporations Code, Section 317 (relating to
indemnification of agents of the corporation), (iii) a transaction within the
provisions of California Corporations Code, Sections 181 and 1201 (relating to
reorganization), and (iv) a plan of distribution within the provisions of
California Corporations Code, Section 2007 (relating to certain plans providing
for distribution not in accordance with the liquidation rights of preferred
shares, if any), the notice shall be given at least ten (10) days before the
consummation of any action authorized by that approval.

     SECTION 14.  VOTING.  The shareholders entitled to vote at any meeting of
shareholders shall be determined in accordance with the provisions of Section 15
of these bylaws, subject to the provisions of Sections 702 through 704 of the
California Corporations Code (relating to voting shares held by a fiduciary, in
the name of a corporation, or in joint ownership).  Voting at any meeting of
shareholders need not be by ballot; provided, however, that elections for
directors must be by ballot if balloting is demanded by a shareholder at the
meeting and before the voting begins.

     Every person entitled to vote at an election for directors may cumulate the
votes to which such person is entitled, i.e., such person may cast a total
number of votes equal to the number of directors to be elected multiplied by the
number of votes to which such person's shares are entitled, and may cast said
total number of votes for one or more candidates in such proportions as such
person thinks fit; provided, however, no shareholder shall be entitled to so
cumulate such shareholder's votes unless the candidates for which such
shareholder is voting have been placed in nomination prior to the voting and a
shareholder has given notice at the meeting, prior to the vote, of an intention
to cumulate votes.  In any election of directors, the candidates receiving the
highest number of votes, up to the number of directors to be elected, are
elected.

     Except as may be otherwise provided in the Articles of Incorporation or by
law, and subject to the foregoing provisions regarding the cumulation of votes,
each shareholder shall be entitled to one vote for each share held.

     Any shareholder may vote part of such shareholder's shares in favor of a
proposal and refrain from voting the remaining shares or vote them against the
proposal, other than elections to office, but, if the shareholder fails to
specify the number of shares such shareholder is voting affirmatively, it will
be conclusively presumed that the shareholder's approving vote is with respect
to all shares such shareholder is entitled to vote.

                                      6.

 
     No shareholder approval, other than unanimous approval of those entitled to
vote, will be valid as to proposals described in subsection 8(d) of these bylaws
unless the general nature of such business was stated in the notice of meeting
or in any written waiver of notice.

     SECTION 15.  PERSONS ENTITLED TO VOTE OR CONSENT.  The Board of Directors
may fix a record date pursuant to Section 60 of these bylaws to determine which
shareholders are entitled to notice of and to vote at a meeting or consent to
corporate actions, as provided in Sections 13 and 14 of these bylaws.  Only
persons in whose name shares otherwise entitled to vote stand on the stock
records of the corporation on such date shall be entitled to vote or consent.

     If no record date is fixed:

          (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 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;

          (b) The record date for determining shareholders entitled to give
consent to corporate action in writing without a meeting, when no prior action
by the Board of Directors has been taken, shall be the day on which the first
written consent is given;

          (c) The record date for determining shareholders for any other purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto, or the sixtieth (60th) day prior to the
date of such other action, whichever is later.

     A determination of shareholders of record entitled to notice of or to vote
at a meeting of shareholders shall apply to any adjournment of the meeting
unless the Board of Directors fixes a new record date for the adjourned meeting;
provided, however, that the Board of Directors shall fix a new record date if
the meeting is adjourned for more than forty-five (45) days from the date set
for the original meeting.

     Shares of the corporation held by its subsidiary or subsidiaries (as
defined in California Corporations Code, Section 189(b)) are not entitled to
vote in any matter.

     SECTION 16.  PROXIES.  Every person entitled to vote or execute consents
may do so either in person or by one or more agents authorized to act by a
written proxy executed by the person or such person's duly authorized agent and
filed with the Secretary of the corporation; provided that no such proxy shall
be valid after the expiration of eleven (11) months from the date of its
execution unless otherwise provided in the proxy.  The manner of execution,
suspension, revocation, exercise and effect of proxies is governed by law.

     SECTION 17.  INSPECTORS OF ELECTION.  Before any meeting of shareholders,
the Board of Directors may appoint any persons, other than nominees for office,
to act as inspectors of

                                      7.

 
election at the meeting or its adjournment. If no inspectors of election are so
appointed, the chairman of the meeting may, and on the request of any
shareholder or a shareholder's proxy shall, appoint inspectors of election at
the meeting.  The number of inspectors shall be either one (1) or three (3).  If
inspectors are appointed at a meeting on the request of one or more shareholders
or proxies, the majority of shares represented in person or proxy 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, 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.

     These inspectors shall:

          (a) Determine the number of shares outstanding and the voting power of
each, the 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 IV

                              BOARD OF DIRECTORS

     SECTION 18.  POWERS.  Subject to the provisions of law or any limitations
in the Articles of Incorporation or these bylaws, as to action required to be
approved by the shareholders or by the outstanding 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.  The Board of
Directors 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.

                                      8.

 
     SECTION 19.  NUMBER OF DIRECTORS.  The authorized number of directors of
the corporation shall be not less than a minimum of five (5) nor more than a
maximum of nine (9) and the number of directors presently authorized is eight
(8).  The exact number of directors shall be set within these limits from time
to time (a) by approval of the Board of Directors, or (b) 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
at least a majority of the required quorum) or by the written consent of
shareholders pursuant to Section 13 hereinabove.

     Any amendment of these bylaws changing the maximum or minimum number of
directors may be adopted only by the affirmative vote of a majority of the
outstanding shares entitled to vote; provided, an amendment reducing the minimum
number of directors to less than five (5), cannot be adopted if votes cast
against its adoption at a meeting or the shares not consenting to it in the case
of action by written consent are equal to more than 16-2/3 percent of the
outstanding shares entitled to vote.

     No reduction of the authorized number of directors shall remove any
director prior to the expiration of such director's term of office.

     SECTION 20.  ELECTION OF DIRECTORS, TERM, QUALIFICATIONS.  The directors
shall be elected at each annual meeting of shareholders to hold office until the
next annual meeting.  Each director, including a director elected or appointed
to fill a vacancy, shall hold office either until the expiration of the term for
which elected or appointed and until a successor has been elected and qualified,
or until his death, resignation or removal.  Directors need not be shareholders
of the corporation.

     SECTION 21.  RESIGNATIONS.  Any director of the corporation may resign
effective upon giving written notice to the Chairman of the 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 specifies effectiveness at a future time, a successor may be
elected pursuant to Section 23 of these bylaws to take office on the date that
the resignation becomes effective.

     SECTION 22.  REMOVAL.  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 who has been convicted of a felony.

     The entire Board of Directors or any individual director may be removed
from office without cause by the affirmative vote of a majority of the
outstanding shares entitled to vote on such removal; provided, however, that
unless the entire Board is removed, no individual director may be removed when
the votes cast against such director's removal, or not consenting in writing to
such removal, would be sufficient to elect that director if voted cumulatively
at an election at which the same total number of votes cast 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 such director's
most recent election were then being elected.

                                      9.

 
     SECTION 23.  VACANCIES.  A vacancy or vacancies on the Board of Directors
shall be deemed to exist in case of the death, resignation or removal of any
director, or upon increase in the authorized number of directors or if
shareholders fail to elect the full authorized number of directors at an annual
meeting of shareholders or if, for whatever reason, there are fewer directors on
the Board of Directors, than the full number authorized.  Such vacancy or
vacancies, other than a vacancy created by the removal of a director, may be
filled by a majority of the remaining directors, though less than a quorum, or
by a sole remaining director.  A vacancy created by the removal of a director
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 at least a majority of the
required quorum) or by the written consent of shareholders pursuant to Section
13 hereinabove.  The  shareholders may elect a director at any time to fill any
vacancy not filled by the directors.  Any such election by written consent,
other than to fill a vacancy created by removal, requires the consent of a
majority of the outstanding shares entitled to vote.  Any such election by
written consent to fill a vacancy created by removal requires the consent of all
of the outstanding shares entitled to vote.

     SECTION 24.  REGULAR MEETINGS.  Regular meetings of the Board of
Directors shall be held at such times, places and dates as fixed in these bylaws
or by the Board of Directors; provided, however, that if the date for such a
meeting falls on a legal holiday, then the meeting shall be held at the same
time on the next succeeding full business day.  Regular meetings of the Board of
Directors held pursuant to this Section 24 may be held without notice.

     SECTION 25.  PARTICIPATION BY TELEPHONE.  Members of the Board of
Directors 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.  Such participation constitutes presence in person
at such meeting.

     SECTION 26.  SPECIAL MEETINGS.  Special meetings of the Board of
Directors for any purpose may be called by the Chairman of the Board or the
President or any vice president or the Secretary of the corporation or any two
(2) directors.

     SECTION 27.  NOTICE OF MEETINGS.  Notice of the date, time and place of
all meetings of the Board of Directors, other than regular meetings held
pursuant to Section 24 above shall be delivered personally, orally or in
writing, or by telephone or telegraph to each director, at least forty-eight
(48) hours before the meeting, or sent in writing to each director by first-
class mail, charges prepaid, at least four (4) days before the meeting.  Such
notice may be given by the Secretary of the corporation or by the person or
persons who called a meeting.  Such notice need not specify the purpose of the
meeting.  Notice of any meeting of the Board of Directors need not be given to
any director who signs a waiver of notice of such meeting, or a consent to
holding the meeting or an approval of the minutes thereof, either before or
after the meeting, or who attends the meeting without protesting prior thereto
or at its commencement such director's lack of notice.  All such waivers,
consents and approvals shall be filed with the corporate records or made a part
of the minutes of the meeting.

                                      10.

 
     SECTION 28.  PLACE OF MEETINGS.  Meetings of the Board of Directors may be
held at any place within or without the state which has been designated in the
notice of the meeting or, if not stated in the notice or there is no notice,
designated in the bylaws or by resolution of the Board of Directors.

     SECTION 29.  ACTION BY WRITTEN CONSENT WITHOUT A MEETING.  Any action
required or permitted to be taken by the Board of Directors may be taken without
a meeting, if all members of the Board of Directors 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 of Directors.  Such
action by written consent shall have the same force and effect as a unanimous
vote of such directors.

     SECTION 30.  QUORUM AND TRANSACTION OF BUSINESS.  A majority of the
authorized number of directors shall constitute a quorum for the transaction of
business.  Every act or decision done or made by a majority of the authorized
number of directors present at a meeting duly held at which a quorum is present
shall be the act of the Board of Directors, unless the law, the Articles of
Incorporation or these bylaws specifically require a greater number.  A meeting
at which a quorum is initially present may continue to transact business,
notwithstanding withdrawal of directors, if any action taken is approved by at
least a majority of the number of directors constituting a quorum for such
meeting.  In the absence of a quorum at any meeting of the Board of Directors, a
majority of the directors present may adjourn the meeting, as provided in
Section 31 of these bylaws.

     SECTION 31.  ADJOURNMENT.  Any meeting of the Board of Directors, whether
or not a quorum is present, may be adjourned to another time and place by the
affirmative vote of a majority of the directors present.  If the meeting is
adjourned for more than twenty-four (24) hours, notice of such 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 32.  ORGANIZATION.  The Chairman of the Board shall preside at
every meeting of the Board of Directors, if present.  If there is no Chairman of
the Board or if the Chairman is not present, a Chairman chosen by a majority of
the directors present shall act as chairman.  The Secretary of the corporation
or, in the absence of the Secretary, any person appointed by the Chairman shall
act as secretary of the meeting.

     SECTION 33.  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 the Board of Directors.

     SECTION 34.  COMMITTEES.  The Board of Directors may, by resolution
adopted by a majority of the authorized number of directors, designate one or
more committees, each consisting of two (2) or more directors, to serve at the
pleasure of the Board of Directors.  The Board of Directors, by a vote of the
majority of authorized directors, may designate one or more directors as
alternate members of any committee, to replace any absent member at any meeting
of such committee.  Any such committee shall have authority to act in the manner
and to the extent provided in the resolution of the Board of Directors, and may
have

                                      11.

 
all the authority of the Board of Directors in the management of the business
and affairs of the corporation, except with respect to:

          (a) the approval of any action for which shareholders' approval or
approval of the outstanding shares also is required by the California
Corporations Code;

          (b) the filling of vacancies on the Board of Directors or any of its
committees;

          (c) the fixing of compensation of directors for serving on the Board
of Directors or any of its committees;

          (d) the adoption, amendment or repeal of these bylaws;

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

          (f) a distribution to shareholders, except at a rate or in a periodic
amount or within a price range determined by the Board of Directors; or

          (g) the appointment of other committees of the Board of Directors or
the members thereof.

     Any committee may from time to time provide by resolution for regular
meetings at specified times and places.  If the date of such a meeting falls on
a legal holiday, then the meeting shall be held at the same time on the next
succeeding full business day.  No notice of such a meeting need be given.  Such
regular meetings need not be held if the committee shall so determine at any
time before or after the time when such meeting would otherwise have taken
place.  Special meetings may be called at any time in the same manner and by the
same persons as stated in Sections 26 and 27 of these bylaws for meetings of the
Board of Directors.  The provisions of Sections 25, 28, 29, 30, 31 and 32 of
these bylaws shall apply to committees, committee members and committee meetings
as if the words "committee" and "committee member" were substituted for the word
"Board of Directors", and "director", respectively, throughout such sections.

time delegate the powers or duties of such officer to any other officer, or any
director or other person whom it may select, for such period of time as the
Board of Directors deems necessary.

     SECTION 38.  RESIGNATIONS.  Any officer may resign at any time upon
written notice to the corporation, without prejudice to the rights, if any, of
the corporation under any contract to which such officer is a party.  Such
resignation shall be effective upon its receipt by the Chairman of the Board,
the President, the Secretary or the Board of Directors, unless a different time
is specified in the notice for effectiveness of such resignation.  The
acceptance of any such resignation shall not be necessary to make it effective
unless otherwise specified in such notice.

be such an officer, shall, if present, preside at all meetings of the Board of
Directors and shall exercise and perform such other powers and duties as may be

manager and chief executive officer of the corporation, and shall exercise all
powers of the President described in Section 42 below.

     SECTION 42.  PRESIDENT.  Subject to such powers, if any, as may be given
by the Board of Directors to the Chairman of the Board, if there be such an
officer, the President shall be the general manager and chief executive officer
of the corporation and shall have general supervision, direction, and control

Vice President and by the Chief Financial Officer or an assistant financial
officer or by 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 upon a certificate shall have ceased to be such officer, transfer agent
or registrar 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.

     In the event that the corporation shall issue any shares as only partly
paid, the certificate issued to represent such partly paid shares shall have
stated thereon the total consideration to be paid for such shares and the amount
paid thereon.

     SECTION 52.  TRANSFER ON THE BOOKS.  Upon surrender to the Secretary or
transfer agent (if any) of the corporation of a certificate for shares of the
corporation duly endorsed, with reasonable assurance that the endorsement is
genuine and effective, or accompanied by proper evidence of succession,
assignment or authority to transfer and upon compliance with applicable federal
and state securities laws and if the corporation has no statutory duty to
inquire into adverse claims or has discharged any such duty and if any
applicable law relating to the collection of taxes has been complied with, it
shall be the duty of the corporation, by its Secretary or transfer agent, to
cancel the old certificate, to issue a new certificate to the person entitled
thereto and to record the transaction on the books of the corporation.

     SECTION 53.  LOST, DESTROYED AND STOLEN CERTIFICATES.  The holder of any
certificate for shares of the corporation alleged to have been lost, destroyed
or stolen shall notify the corporation by making a written affidavit or
affirmation of such fact.  Upon receipt of said affidavit or affirmation the
Board of Directors, or its duly appointed and authorized committee or any
officer or officers authorized by the Board so to do, may order the issuance of
a new certificate for shares in the place of any certificate previously issued
by the corporation and which is alleged to have been lost, destroyed or stolen.
However, the Board of Directors or such authorized committee, officer or
officers may require the owner of the allegedly lost, destroyed or stolen
certificate, or such owner's legal representative, to give the corporation a
bond or other adequate security sufficient to indemnify the corporation and its
transfer agent and/or registrar, if any, against any claim that may be made
against it or them on account of such allegedly lost, destroyed or stolen
certificate or the replacement thereof. Said bond or other security shall be in
such amount, on such terms and conditions

                                      17.

 
and, in the case of a bond, with such surety or sureties as may be acceptable to
the Board of Directors or to its duly appointed and authorized committee or any
officer or officers authorized by the Board of Directors to determine the
sufficiency thereof.  The requirement of a bond or other security may be waived
in particular cases at the discretion of the Board of Directors or its duly
appointed and authorized committee or any officer or officers authorized by the
Board of Directors so to do.

     SECTION 54.  ISSUANCE, TRANSFER AND REGISTRATION OF SHARES.  The Board of
Directors may make such rules and regulations, not inconsistent with law or with
these bylaws, as it may deem advisable concerning the issuance, transfer and
registration of certificates for shares of the capital stock of the corporation.
The Board of Directors may appoint a transfer agent or registrar of transfers,
or both, and may require all certificates for shares of the corporation to bear
the signature of either or both.


                                 ARTICLE VIII

                        INSPECTION OF CORPORATE RECORDS

     SECTION 55.  INSPECTION BY DIRECTORS.  Every director shall have the
absolute right at any reasonable time to inspect and copy all books, records,
and documents of every kind of the corporation and any of its subsidiaries and
to inspect the physical properties of the corporation and any of its
subsidiaries.  Such inspection may be made by the director in person or by agent
or attorney, and the right of inspection includes the right to copy and make
extracts.

     SECTION 56.  INSPECTION BY SHAREHOLDERS.

          (a) INSPECTION OF CORPORATE RECORDS.

              (1) A shareholder or shareholders holding at least five (5%) 
percent in the aggregate of the outstanding voting shares of the corporation or
who hold at least one percent of such voting shares and have filed a Schedule
14B with the United States Securities and Exchange Commission relating to the
election of directors of the corporation shall have an absolute right to do
either or both of the following:

                  (i)    Inspect and copy the record of shareholders' names and 
addresses and shareholdings during usual business hours upon five (5) business
days' prior written demand upon the corporation; or

                  (ii)   Obtain from the transfer agent, if any, for the 
corporation, upon five business days' prior written demand and upon the tender
of its usual charges for such a list (the amount of which charges shall be
stated to the shareholder by the transfer agent upon request), a list of the
shareholders' names and addresses who are entitled to vote for the election of
directors and their shareholdings, as of the most recent record date

                                      18.

 
for which it has been compiled or as of a date specified by the shareholder
subsequent to the date of demand.

          (2) The record of shareholders shall also be open to inspection and
copying by any shareholder or holder of a voting trust certificate at any time
during usual business hours upon written demand on the corporation, for a
purpose reasonably related to such holder's interest as a shareholder or holder
of a voting trust certificate.

          (3) The accounting books and records and minutes of proceedings of the
shareholders and the Board of Directors and of any committees of the Board of
Directors of the corporation and of each of its subsidiaries shall be open to
inspection, copying and making extracts upon written demand on the corporation
of any shareholder or holder of a voting trust certificate at any reasonable
time during usual business hours, for a purpose reasonably related to such
holder's interests as a shareholder or as a holder of such voting trust
certificate.

          (4) Any inspection, copying, and making of extracts under this
subsection (a) may be done in person or by agent or attorney.

     (b) INSPECTION OF BYLAWS.  The original or a copy of these bylaws
shall be kept as provided in Section 44 of these bylaws and shall be open to
inspection by the shareholders at all reasonable times during office hours.  If
the principal executive office of the corporation is not in California, and the
corporation has no principal business office in the state of California, a
current copy of these bylaws shall be furnished to any shareholder upon written
request.

     SECTION 57.  WRITTEN FORM.  If any record subject to inspection pursuant
to Section 56 above is not maintained in written form, a request for inspection
is not complied with unless and until the corporation at its expense makes such
record available in written form.


                                  ARTICLE IX

                                 MISCELLANEOUS

     SECTION 58.  FISCAL YEAR.  Unless otherwise fixed by resolution of the
Board of Directors, the fiscal year of the corporation shall end on the 30th day
of April in each calendar year.

     SECTION 59.  ANNUAL REPORT.

          (a) Subject to the provisions of Section 59(b) below, the Board of
Directors shall cause an annual report to be sent to each shareholder of the
corporation in the manner provided in Section 9 of these bylaws not later than
one hundred twenty (120) days after the close of the corporation's fiscal year.
Such report shall include a balance sheet as of the end

                                      19.

 
of such fiscal year and an income statement and statement of changes in
financial position for such fiscal year, accompanied by any report thereon of
independent accountants or, if there is no such report, the certificate of an
authorized officer of the corporation that such statements were prepared without
audit from the books and records of the corporation.  When there are more than
100 shareholders of record of the corporation's shares, as determined by Section
605 of the California Corporations Code, additional information as required by
Section 1501(b) of the California Corporations Code shall also be contained in
such report, provided that if the corporation has a class of securities
registered under Section 12 of the United States Securities Exchange Act of
1934, that Act shall take precedence.  Such report shall be sent to shareholders
at least fifteen (15) (or, if sent by third-class mail, thirty-five (35)) days
prior to the next annual meeting of shareholders after the end of the fiscal
year to which it relates.

          (b) If and so long as there are fewer than 100 holders of record of
the corporation's shares, the requirement of sending of an annual report to the
shareholders of the corporation is hereby expressly waived.

     SECTION 60.  RECORD DATE.  The Board of Directors may fix a time in the
future as a record date for the determination of the shareholders entitled to
notice of or to vote at any meeting or entitled to receive payment of any
dividend or other distribution or allotment of any rights or entitled to
exercise any rights in respect of any change, conversion or exchange of shares
or entitled to exercise any rights in respect of any other lawful action.  The
record date so fixed shall not be more than sixty (60) days nor less than ten
(10) days prior to the date of the meeting nor more than sixty (60) days prior
to any other action or event for the purpose of which it is fixed.  If no record
date is fixed, the provisions of Section 15 of these bylaws shall apply with
respect to notice of meetings, votes, and consents and the record date for
determining shareholders for any other purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolutions relating
thereto, or the sixtieth (60th) day prior to the date of such other action or
event, whichever is later.

     Only shareholders of record at the close of business on the record date
shall be entitled to notice and to vote or to receive the dividend, distribution
or allotment of rights or to exercise the rights, 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 Articles of Incorporation,
by agreement or by law.

     SECTION 61.  BYLAW AMENDMENTS.  Except as otherwise provided by law or
Section 19 of these bylaws, these bylaws may be amended or repealed by the Board
of Directors or by the affirmative vote of a majority of the outstanding shares
entitled to vote, including, if applicable, the affirmative vote of a majority
of the outstanding shares of each class or series entitled by law or the
Articles of Incorporation to vote as a class or series on the amendment or
repeal or adoption of any bylaw or bylaws; provided, however, after issuance of
shares, a bylaw specifying or changing a fixed number of directors or the
maximum or minimum number or changing from a fixed to a variable board or vice
versa may only be adopted by approval of the outstanding shares as provided
herein.

                                      20.

 
     SECTION 62.  CONSTRUCTION AND DEFINITION.  Unless the context requires
otherwise, the general provisions, rules of construction, and definitions
contained in the California Corporations Code shall govern the construction of
these bylaws.

     Without limiting the foregoing, "shall" is mandatory and "may" is
permissive.


                                   ARTICLE X

                                INDEMNIFICATION

     SECTION 63.  INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND OTHER
                  AGENTS.

          (a) DIRECTORS AND EXECUTIVE OFFICERS.  The corporation shall indemnify
its directors and executive officers to the fullest extent not prohibited by the
California General Corporation Law; provided, however, that the corporation may
                                    --------  -------                          
limit the extent of such indemnification by individual contracts with its
directors and executive officers; and, provided, further, that the corporation
                                       --------  -------                      
shall not be required to indemnify any director or executive officer in
connection with any proceeding (or part thereof) initiated by such person or any
proceeding by such person against the corporation or its directors, officers,
employees or other agents unless (i) such indemnification is expressly required
to be made by law, (ii) the proceeding was authorized by the board of directors
of the corporation or (iii) such indemnification is provided by the corporation,
in its sole discretion, pursuant to the powers vested in the corporation under
the California General Corporation Law.

          (b) OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS.  The corporation shall
have the power to indemnify its other officers, employees and other agents as
set forth in the California General Corporation Law.

          (c) DETERMINATION BY THE CORPORATION.  Promptly after receipt of a
request for indemnification hereunder (and in any event within 90 days thereof)
a reasonable, good faith determination as to whether indemnification of the
director or executive officer is proper under the circumstances because such
director or executive officer has met the applicable standard of care shall be
made by:

              (1) a majority vote of a quorum consisting of directors who are
not parties to such proceeding;

              (2) if such quorum is not obtainable, by independent legal
counsel in a written opinion; or

              (3) approval or ratification by the affirmative vote of a 
majority of the shares of this corporation represented and voting at a duly held
meeting at which a quorum is present (which shares voting affirmatively also
constitute at least a majority of the required quorum) or by written consent of
a majority of the outstanding shares entitled to

                                      21.

 
vote; where in each case the shares owned by the person to be indemnified shall
not be considered entitled to vote thereon.

          (d)  GOOD FAITH.

               (1)  For purposes of any determination under this bylaw, a 
director or executive officer shall be deemed to have acted in good faith and in
a manner he reasonably believed to be in the best interests of the corporation
and its shareholders, and, with respect to any criminal action or proceeding, to
have had no reasonable cause to believe that his conduct was unlawful, if his
action is based on information, opinions, reports and statements, including
financial statements and other financial data, in each case prepared or
presented by:

                    (i)    one or more officers or employees of the corporation 
whom the director or executive officer believed to be reliable and competent in
the matters presented;

                    (ii)   counsel, independent accountants or other persons as 
to matters which the director or executive officer believed to be within such
person's professional competence; and

                    (iii)  with respect to a director, a committee of the
Board upon which such director does not serve, as to matters within such
committee's designated authority, which committee the director believes to merit
confidence; so long as, in each case, the director or executive officer acts
without knowledge that would cause such reliance to be unwarranted.

               (2) The termination of any proceeding by judgment, order, 
settlement, conviction or upon a plea of nolo contendere or its equivalent shall
not, of itself, create a presumption that the person did not act in good faith
and in a manner which he reasonably believed to be in the best interests of the
corporation and its shareholders or that he had reasonable cause to believe that
his conduct was unlawful.

               (3) The provisions of this paragraph (d) shall not be deemed to 
be exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth by the
California General Corporation Law.

          (e) EXPENSES.  The corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by any director or executive officer in connection with such proceeding
upon receipt of an undertaking by or on behalf of such person to repay said
amounts if it shall be determined ultimately that such person is not entitled to
be indemnified under this bylaw or otherwise.

     Notwithstanding the foregoing, unless otherwise determined pursuant to
paragraph (f) of this bylaw, no advance shall be made by the corporation if a
determination is reasonably and promptly made by the Board of Directors by a
majority vote of a quorum consisting of

                                      22.

 
directors who were not parties to the proceeding (or, if no such quorum exists,
by independent legal counsel in a written opinion) that the facts known to the
decision making party at the time such determination is made demonstrate clearly
and convincingly that such person acted in bad faith or in a manner that such
person did not believe to be in the best interests of the corporation and its
shareholders.

          (f) ENFORCEMENT.  Without the necessity of entering into an express
contract, all rights to indemnification and advances to directors and executive
officers under this bylaw shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the director or executive officer.  Any right to indemnification
or advances granted by this bylaw to a director or executive officer shall be
enforceable by or on behalf of the person holding such right in the forum in
which the proceeding is or was pending or, if such forum is not available or a
determination is made that such forum is not convenient, in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor.  The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim.  The corporation shall be entitled to raise as a
defense to any such action that the claimant has not met the standards of
conduct that make it permissible under the California General Corporation Law
for the corporation to indemnify the claimant for the amount claimed.  Neither
the failure of the corporation (including its board of directors, independent
legal counsel or its shareholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in the California General Corporation Law, nor an actual determination by
the corporation (including its board of directors, independent legal counsel or
its shareholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

          (g) NON-EXCLUSIVITY OF RIGHTS.  To the fullest extent permitted by the
corporation's Articles of Incorporation and the California General Corporation
Law, the rights conferred on any person by this bylaw shall not be exclusive of
any other right which such person may have or hereafter acquire under any
statute, provision of the Articles of Incorporation, bylaws, agreement, vote of
shareholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding office.
The corporation is specifically authorized to enter into individual contracts
with any or all of its directors, officers, employees or agents respecting
indemnification and advances, to the fullest extent permitted by the California
General Corporation Law and the corporation's Articles of Incorporation.

          (h) SURVIVAL OF RIGHTS.  The rights conferred on any person by this
bylaw shall continue as to a person who has ceased to be a director or executive
officer and shall inure to the benefit of the heirs, executors and
administrators of such a person.

                                      23.

 
          (i) INSURANCE.   The corporation, upon approval by the board of
directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this bylaw.

          (j) AMENDMENTS.  Any repeal or modification of this bylaw shall only
be prospective and shall not affect the rights under this bylaw in effect at the
time of the alleged occurrence of any action or omission to act that is the
cause of any proceeding against any agent of the corporation.

          (k) EMPLOYEE BENEFIT PLANS.   The corporation shall indemnify the
directors and officers of the corporation who serve at the request of the
corporation as trustees, investment managers or other fiduciaries of employee
benefit plans to the fullest extent permitted by the California General
Corporation Law.

          (l) SAVING CLAUSE.  If this bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director and executive officer to
the fullest extent permitted by any applicable portion of this bylaw that shall
not have been invalidated, or by any other applicable law.

          (m) CERTAIN DEFINITIONS.   For the purposes of this bylaw, the
following definitions shall apply:

              (1) The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement and appeal of any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative, arbitrative or
investigative.

              (2) The term "expenses" shall be broadly construed and shall 
include, without limitation, court costs, attorneys' fees, witness fees, fines,
amounts paid in settlement or judgment and any other costs and expenses of any
nature or kind incurred in connection with any proceeding, including expenses of
establishing a right to indemnification under this bylaw or any applicable law.

              (3) The term the "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this bylaw with respect to the resulting or surviving corporation as he would
have with respect to such constituent corporation if its separate existence had
continued.

              (4) References to a "director," "officer," "employee," or "agent" 
of the corporation shall include, without limitation, situations where such
person is or was

                                      24.

 
serving at the request of the corporation as a director, officer, employee,
trustee or agent of another corporation, partnership, joint venture, trust or
other enterprise.


                                  ARTICLE XI

                            RIGHT OF FIRST REFUSAL

     SECTION 64.  RIGHT OF FIRST REFUSAL.  No shareholder shall sell,
assign, pledge, or in any manner transfer any of the shares of Common Stock of
the corporation or any right or interest therein, whether voluntarily or by
operation of law, or by gift or otherwise, except by a transfer which meets the
requirements hereinafter set forth in this bylaw:

          (a) If the shareholder desires to sell or otherwise transfer any of
his shares of Common Stock, then the shareholder shall first give written notice
thereof to the corporation.  The notice shall name the proposed transferee and
state the number of shares to be transferred, the proposed consideration, and
all other terms and conditions of the proposed transfer.

          (b) For thirty (30) days following receipt of such notice, the
corporation shall have the option to purchase all (but not less than all) of the
shares specified in the notice at the price and upon the terms set forth in such
notice; provided, however, that, with the consent of the shareholder, the
corporation shall have the option to purchase a lesser portion of the shares
specified in said notice at the price and upon the terms set forth therein.  In
the event of a gift, property settlement or other transfer in which the proposed
transferee is not paying the full price for the shares, and that is not
otherwise exempted from the provisions of this Section 64, the price shall be
deemed to be the fair market value of the stock at such time as determined in
good faith by the Board of Directors.  In the event the corporation elects to
purchase all of the shares or, with consent of the shareholder, a lesser portion
of the shares, it shall give written notice to the transferring shareholder of
its election and settlement for said shares shall be made as provided below in
paragraph (d).

          (c) The corporation may assign its rights hereunder.

          (d) In the event the corporation and/or its assignee(s) elect to
acquire any of the shares of the transferring shareholder as specified in said
transferring shareholder's notice, the Secretary of the corporation shall so
notify the transferring shareholder and settlement thereof shall be made in cash
within thirty (30) days after the Secretary of the corporation receives said
transferring shareholder's notice; provided that if the terms of payment set
forth in said transferring shareholder's notice were other than cash against
delivery, the corporation and/or its assignee(s) shall pay for said shares on
the same terms and conditions set forth in said transferring shareholder's
notice.

          (e) In the event the corporation and/or its assignees(s) do not elect
to acquire all of the shares specified in the transferring shareholder's notice,
said transferring shareholder may, within the sixty-day period following the
expiration of the option rights

                                      25.

 
granted to the corporation and/or its assignees(s) herein, transfer the shares
specified in said transferring shareholder's notice which were not acquired by
the corporation and/or its assignees(s) as specified in said transferring
shareholder's notice.  All shares so sold by said transferring shareholder shall
continue to be subject to the provisions of this bylaw in the same manner as
before said transfer.

          (f) Anything to the contrary contained herein notwithstanding, the
following transactions shall be exempt from the provisions of this bylaw:

              (1) A shareholder's transfer of any or all shares held either 
during such shareholder's lifetime or on death by will or intestacy to such
shareholder's immediate family or to any custodian or trustee for the account of
such shareholder or such shareholder's immediate family. "Immediate family" as
used herein shall mean spouse, lineal descendant, father, mother, brother, or
sister of the shareholder making such transfer.

              (2) A shareholder's bona fide pledge or mortgage of any shares 
with a commercial lending institution, provided that any subsequent transfer of
said shares by said institution shall be conducted in the manner set forth in
this bylaw.

              (3) A shareholder's transfer of any or all of such shareholder's
shares to the corporation or to any other shareholder of the corporation.

              (4) A shareholder's transfer of any or all of such shareholder's
shares to a person who, at the time of such transfer, is an officer or director
of the corporation.

              (5) A corporate shareholder's transfer of any or all of its shares
pursuant to and in accordance with the terms of any merger, consolidation,
reclassification of shares or capital reorganization of the corporate
shareholder, or pursuant to a sale of all or substantially all of the stock or
assets of a corporate shareholder.

              (6) A corporate shareholder's transfer of any or all of its
shares to any or all of its shareholders.

              (7) A transfer by a shareholder which is a limited or general
partnership to any or all of its partners or former partners.

          In any such case, the transferee, assignee, or other recipient shall
receive and hold such stock subject to the provisions of this bylaw, and there
shall be no further transfer of such stock except in accord with this bylaw.

          (g) The provisions of this bylaw may be waived with respect to any
transfer either by the corporation, upon duly authorized action of its Board of
Directors, or by the shareholders, upon the express written consent of the
owners of a majority of the voting power of the corporation (excluding the votes
represented by those shares to be transferred by the transferring shareholder).
This bylaw may be amended or repealed either

                                      26.

 
by a duly authorized action of the Board of Directors or by the shareholders,
upon the express written consent of the owners of a majority of the voting power
of the corporation.

          (h) Any sale or transfer, or purported sale or transfer, of securities
of the corporation shall be null and void unless the terms, conditions, and
provisions of this bylaw are strictly observed and followed.

                         LOANS TO OFFICERS AND OTHERS

     SECTION 65.  CERTAIN CORPORATE LOANS AND GUARANTIES.  If the
corporation has outstanding shares held of record by 100 or more persons on the
date of approval by the Board of Directors, the corporation may make loans of
money or property to, or guarantee the obligations of, any officer of the
corporation or its parent or any subsidiary, whether or not a director of the
corporation or its parent or any subsidiary, or adopt an employee benefit plan
or plans authorizing such loans or guaranties, upon the approval of the Board of
Directors alone, by a vote sufficient without counting the vote of any
interested director or directors, if the Board of Directors determines that such
a loan or guaranty or plan may reasonably be expected to benefit the
corporation.  Notwithstanding the foregoing, the corporation shall have the
power to make loans permitted by the California Corporations Code.
