                            Meetings of Shareholders

Section 3. Place of Meetings.
         Meetings  of the  shareholders  shall be held at any  place  within  or
outside the State of California  that may be  designated  either by the Board of
Directors in accordance  with these  By-Laws,  or by the written  consent of all
persons  entitled to vote at the meeting,  given either before,  during or after
the  meeting  and  filed  with  the  Secretary  of the  corporation.  If no such
designation is made,  the meetings shall be held at the principal  office of the
corporation designated in Section 1 of these By-Laws.

Section  4.     Annual Meetings.
         The  annual  meeting  of the  shareholders  shall be held on the second
Thursday in March each year,  if not a legal  holiday,  and if a legal  holiday,
then on the next  succeeding  business  day, at the hour of 10:00 A.M., at which
time the shareholders shall elect a Board of Directors,  consider reports of the
affairs of the corporation,  and transact such other business as may properly be
brought before the meeting.

          If the annual  meeting of  shareholders  shall not be held on the date
above specified, the Board of Directors shall cause such a meeting to be held as
soon thereafter as convenient,  and any business  transacted or election held at
such meeting shall be as valid as if transacted or held at an annual  meeting on
the date above specified.

Section 5. Special Meetings.
          Special  meetings  of the  shareholders,  for any  purpose or purposes
whatsoever, may be called at any time by the Board of Directors, Chairman of the
Board, the President,  or by holders of shares entitled to cast not less than 10
percent of the votes at the meeting.

Section 6. Notice of Shareholders' Meetings.
         Whenever shareholders are required or permitted to take any action at a
meeting, a written notice of the meeting shall be given not less than 10 (or, if
sent by  third  class  mail,  30) or more  than 60 days  before  the date of the
meeting to each shareholder  entitled to vote at the meeting.  Such notice shall
state the place,  date and hour of the  meeting and (1) in the case of a special
meeting,  the  general  nature of the  business to be  transacted,  and no other
business  may be  transacted,  or (2) in the case of the annual  meeting,  those
matters  which the Board,  at the time of the mailing of the notice,  intends to
present for action by the shareholders, but subject to the provisions of Section
601(f) of the  Corporations  Code,  any proper  matter may be  presented  at the
meeting for such action.  The notice of any meeting at which directors are to be
elected shall  include the names of nominees  intended at the time of the notice
to be presented by management for election.

                                      - 1 -

         Notice of shareholders'  meeting shall be given either personally or by
first  class mail or other  means of  written  communication,  addressed  to the
shareholder  at the address of such  shareholder  appearing  on the books of the
corporation or given by the  shareholder to the  corporation  for the purpose of
notice;  or if no such  address  appears  or is given,  at the  place  where the
principal  office of the  corporation is located.  The notice shall be deemed to
have been given at the time when  delivered  personally or deposited in the mail
or sent by other means of written communication.

          If any notice  addressed  to the  shareholder  at the  address of such
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 such  address,  all  future  notices  shall be deemed to have been duly given
without further mailing if the same shall be available for the shareholder  upon
written demand of the shareholder at the principal office of the corporation for
a period  of one year  from the date of the  giving  of the  notice to all other
shareholders.

          Upon request in writing to the Chairman of the Board, President,  Vice
President  or  Secretary  by any person  entitled  to call a special  meeting of
shareholders,   the  officer  forthwith  shall  cause  notice  to  be  given  to
shareholders entitled to vote that a meeting will be held at a time requested by
the person or persons  calling  the  meeting,  not less than 35 nor more than 60
days after the receipt of the request.

Section 7. Quorum.
         The  presence  at any  meeting,  in person or by proxy,  of the persons
entitled  to vote a  majority  of the  voting  shares of the  corporation  shall
constitute a quorum for the transaction of business.  Shareholders  present at a
valid meeting at which a quorum is initially present may continue to do business
until adjournment notwithstanding the withdrawal of enough shareholders to leave
less than a quorum,  if any action taken (other than adjournment) is approved by
persons voting more than 25 percent of the voting shares.

Section 8. Adjourned Meeting.
         Any annual or special  shareholders' meeting may be adjourned from time
to time,  even  though a quorum  is not  present,  by vote of the  holders  of a
majority  of the voting  shares  present at the  meeting  either in person or by
proxy,  provided  that in the  absence  of a quorum,  no other  business  may be
transacted at the meeting except as provided in Section 7.

         Notice need not be given of the adjourned meeting if the time and place
thereof are announced at the meeting at which the  adjournment is taken.  At the
adjourned  meeting,  any  business  may be  transacted  which  might  have  been
transacted at the original meeting.  If the adjournment is for more than 45 days
or if after the adjournment, a notice of the adjourned meeting shall be given to
each shareholder of record entitled to vote at the meeting.

Section 9. Waiver of Consent by Shareholders.
         The  transactions  of any meeting of  shareholders,  however called and
noticed,  and wherever held, are as valid as though had a meeting been duly held
after  regular  call and notice,  if a quorum is present  either in person or by
proxy, and if, either before,  during, or after the meeting, each of the persons
entitled to vote,  not present in person or by proxy,  signs a written waiver of
notice or a consent to the  holding of a meeting or an  approval  of the minutes
thereof.  All such  waivers,  consents  and  approvals  shall be filed  with the
corporate records or made a part of the minutes of the meeting.  Attendance of a
person at a meeting shall  constitute a waiver of notice of and presence at such
meeting, except when the person objects, at the beginning of the meeting, to the
transaction  of any  business  because  the  meeting is not  lawfully  called or
convened  and except  that  attendance  at such a meeting is not a waiver of any
right to object to the  consideration  of matters required by Section 6 of these
By-Laws or Section 601(f) of the Corporations  Code to be included in the notice
but not so included, if such objection is expressly made at the meeting. Neither
the  business  to be  transacted  at nor the  purpose of any  regular or special
meeting of  shareholders  need be  specified  in any  written  waiver of notice,
consent to the holding of the meeting or approval of the minutes thereof, except
as provided in Section 601(f) of the Corporations Code.



                                      - 2 -

Section 10.  Action Without Meeting.
         Any  action  which may be taken at any  annual or  special  meeting  of
shareholders  may be taken  without a meeting and  without  prior  notice,  if a
consent in writing,  setting  forth the action so taken,  shall be signed by the
holders of  outstanding  shares  having not less than a 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,  except  that
unanimous  written  consent  shall be  required  for  election of  directors  to
non-vacant positions.

         Unless the  consents  of all  shareholders  entitled  to vote have been
solicited  or  received  in  writing,  notice  shall be given to  non-consenting
shareholders to the extent required by the Corporations Code.

         Any shareholder  giving a written consent,  or the shareholder's  proxy
holder,  or a  transferee  of the shares or a personal  representative  or proxy
holder of the  shareholder,  may revoke the consent by a writing received by the
corporation  prior to the time that  written  consents  of the  number of shares
required to authorize the proposed  action have been filed with the Secretary of
the corporation, but may not do so thereafter. Such revocation is effective upon
its receipt by the Secretary of the corporation.

Section 11.  Voting Rights; Cumulative Voting.
         Only persons in whose names shares  entitled to vote stand on the stock
records of the  corporation at the close of business on the record date fixed by
the Board of  Directors  as  provided  in  Section 40 for the  determination  of
shareholders  of  record  shall be  entitled  to  notice  of and to vote at such
meeting  of  shareholders.  If no record  date is  fixed,  the  record  date for
determining  shareholders  entitled  to  notice  of or to vote at a  meeting  of
shareholders  shall  be at the  close  of  business  on the  business  day  next
preceding the day on which notice is given or, if notice is waived, at the close
of business on the business day next  preceding  the day on which the meeting is
held; the record date for determining  shareholders  entitled to give consent to
corporate  action  by the Board  has been  taken,  shall be the day on which the
first written consent is given; 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 adopts the resolution  relating thereto, or the 60th day prior to the date
of such other action, whichever is later.

         Except as provided in the next following  sentence and except as may be
otherwise provided in the Articles of Incorporation,  each shareholder  entitled
to vote  shall  be  entitled  to one vote for  each  share  held on each  matter
submitted to a vote of  shareholders.  In the election of  directors,  each such
shareholder   complying   with  the   following   paragraph  may  cumulate  such
shareholder's 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 the
shareholder's  shares are normally  entitled,  or distribute  the  shareholder's
votes on the same principle among as many  candidates as the shareholder  thinks
fit.

         No  shareholder  shall be entitled  to  cumulate  votes in favor of any
candidate or candidates unless the name(s) of such  candidate(s)  has(have) been
placed in nomination prior to the voting and the shareholder has given notice at
the meeting prior to the voting, of the shareholder's  intention to cumulate the
shareholder's  votes. If any one  shareholder  has given such notice,  such fact
shall  be  announced  to all  shareholders  and  proxies  present,  who may then
cumulate their votes for candidates in nomination.

         In any election of  directors,  the  candidates  receiving  the highest
number of votes of the shares entitled to be voted for them, up to the number of
directors to be elected by such shares, shall be deemed elected.

         Voting may be by voice or ballot, provided that, upon the demand of any
shareholder  made at the meeting and before the voting  begins,  any election of
directors must be by ballot.

Section 12.  Proxies.
          Every person  entitled to vote shares may authorize  another person or
persons to act by proxy with  respect to such  shares.  All  proxies  must be in
writing  and must be  signed  by the  shareholder  confirming  the  proxy or his
attorney-in-fact. No proxy shall be valid after the expiration of 11 months from
the date thereof,  unless otherwise provided in the proxy. Every proxy continues
in full force and effect until  revoked by the person  executing it prior to the
vote  pursuant  thereto,  except as  otherwise  provided  in Section  705 of the
Corporations Code. Such revocation may be effected by a writing delivered to the
corporation stating that the proxy is revoked or by a subsequent proxy
                                      - 3 -

executed by the person  executing  the prior proxy and presented to the meeting,
or, as to any meeting, by attendance at such meeting and voting in person by the
person  executing  the  proxy.  The  dates  contained  on  the  forms  of  proxy
presumptively determine the order of execution, regardless of the postmark dates
on the envelopes in which they are mailed.

Section 13.  Inspectors of Election.
          In  advance  of any  meeting  of  shareholders  the Board may  appoint
inspectors  of election to act at the meeting and any  adjournment  thereof.  If
inspectors of election are not so appointed, or if any persons so appointed fail
to appear or refuse to act, the chairman of any meeting of shareholders may, and
on the  request of any  shareholder  or a  shareholder's  proxy  shall,  appoint
inspectors  of election  (or persons to replace  those who so fail or refuse) at
the meeting. The number of inspectors shall be either one or three. If appointed
at a meeting on the request of one or more shareholders or proxies, the majority
of shares represented in person or by proxy shall determine whether one or three
inspectors are to be appointed.  If there are three inspectors of election,  the
decision,  act, or certificate of a majority is effective in all respects as the
decision, act, or certificate of all.

         The  inspectors  of  elections  shall  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,  receive votes, ballots or consents,  hear and determine all challenges
and questions in any way arising in connection with the right to vote, count and
tabulate all votes or consents,  determine when the polls shall close, determine
the  result  thereof,  and take such  actions  as may be proper to  conduct  the
election or vote with fairness to all shareholders.

                                   ARTICLE III

                              Directors; Management

Section 14.  Powers.
         Subject to any  provisions of the Articles of  Incorporation,  By-Laws,
and of law limiting the powers of the Board of Directors or reserving  powers to
the  shareholders,  the Board of  Directors  shall,  directly or by  delegation,
manage the business and affairs of the  corporation  and exercise all  corporate
powers permitted by law.

Section 15.  Number and Qualification of Directors.
         The authorized  number of directors shall be not less than Five (5) nor
more than thirteen (13) unless and until changed by an amendment to this Section
15 adopted by the  shareholders  pursuant  to  Section  49. The exact  number of
directors  within said range shall be fixed by an  amendment  to this Section 15
adopted by the Board of  Directors;  and unless and until so amended,  the exact
number of directors  is hereby fixed at five (5). A reduction in the  authorized
number of directors  shall not remove any director  prior to the  expiration  of
such  director's  term of  office.  Directors  need not be  shareholders  of the
corporation.

Section 16.  Election and Term of Office.
         The  directors  shall be elected  annually by the  shareholders  at the
annual  meeting of the  shareholders;  provided,  that if for any  reason,  said
annual  meeting or an  adjournment  thereof is not held or the directors are not
elected at such  meeting,  then the  directors  may be  elected  at any  special
meeting of the shareholders called and held for that purpose. The term of office
of the  directors  shall,  except as provided in Section 17,  begin  immediately
after their election and shall continue  until their  respective  successors are
elected and qualified;  except as otherwise provided herein,  such term shall be
for a period of no less than one year.

Section 17.  Removal of Directors.
         Unless  otherwise  specifically  provided  herein,  a  director  may be
removed from office:

         (a)      by the Board of Directors if he is declared of unsound mind by
the order of court or convicted of a felony;

         (b) without cause by a vote of  shareholders  holding a majority of the
outstanding shares entitled to vote at an election of directors;  howver, unless
the entire Board is removed,  an individual director shall not be removed if the
votes cast against removal, or not consenting in writing to such removal,
                                       -4-

                  would  be   sufficient   to  elect  such   director  if  voted
cumulatively with all authorized  shares voting,  or, if such action is taken by
written consent, all shares entitled to vote were voted, and the entire num- ber
of directors  authorized at the time of the director's most recent election were
then being elected; or
         (c) by the Superior  Court of the county in which the principal  office
is located,  at the suit of  shareholders  holding at least ten percent (10%) of
the number of  outstanding  shares of any class,  in case of any  fraudulent  or
dishonest  act or gross abuse of authority or discretion  with  reference to the
corpo- ration.
         (d)      By the Chairperson of the  Board if the  director remains
absent from three (3) consecutive board meetings.

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

Section 18.  Vacancies.
         A vacancy or  vacancies  on the Board of  Directors  shall exist on the
death,  resignation,  or removal of any director, or if the authorized number of
directors  is increased or the  shareholders  fail to elect the full  authorized
number of directors.

         Except for a vacancy created by the removal of a director, vacancies on
the Board of Directors may be filled by a majority of the  remaining  directors,
although less than a quorum, or by a sole remaining director,  and each director
elected in this  manner  shall hold office  until a  successor  is elected at an
annual or special shareholders' meeting.

         The  shareholders  may elect a director at any time to fill any vacancy
not filled by the directors.  Any such election by written consent  requires the
consent of a majority of the outstanding  shares entitled to vote,  except for a
vote to fill a vacancy created by removal,  which requires the unanimous consent
of the outstanding shares entitled to vote.

         Any  director  may  resign,  effective  as of the date of notice to the
Chairman of the Board, the President,  the Secretary,  or the Board of Directors
of the corporation.

         If such notice is not in  writing,  it shall be  effective  on the date
given only if confirmed by a writing  received  within a reasonable time of such
non-written notice.

Section 19.  Place of Meetings.
          Regular and special  meetings of the Board of Directors  shall be held
at any place within or outside the State of  California  that is  designated  by
resolution of the Board or, either before or after the meeting,  consented to in
writing by a majority of the Board members. If the place of a regular or special
meeting is not fixed by resolution or written consents of the Board, it shall be
held at the corporation's principal office.

Section 20.  Annual Meetings.
         Immediately  following each annual shareholders'  meeting, the Board of
Directors shall hold an annual meeting to organize, elect officers, and transact
other business. Notice of this meeting shall not be required.

Section 21.  Other Regular Meetings.
         Other regular  meetings of the Board of Directors  shall be held on the
second  Tuesday in November of each year,  at the hour of 10:00 A.M.,  provided,
however, if this day falls on a legal holiday,  the meeting shall be held at the
same time on the next  succeeding  day that is a full  business  day.  Notice of
these regular meetings shall not be required.

Section 22.  Special Meetings.
         Special  meetings  of the Board of  Directors  for any  purpose  may be
called at any time by the Chairman of the Board,  or the President,  or any Vice
President, or the Secretary, or any two directors.


                                      -5-

         Special  meetings of the Board shall be held upon four days'  notice by
mail or by 48 hours' notice  delivered  personally or by telephone or telegraph.
If notice is by  telephone,  it shall be  complete  when the person  calling the
meeting  believes  in  good  faith  that  the  notified  person  has  heard  and
acknowledged  the  notice.  If the notice is by mail or  telegraph,  it shall be
complete when  deposited in the United States mail or delivered to the telegraph
office at the place where the corporation's principal office is located, charges
prepaid,  and addressed to the notified  person at such  person's  address as it
appears on the  corporate  records  or, if it is not on these  records or is not
readily ascertainable, at the place where the regular Board meeting is held.

Section 23.  Quorum.
         A majority of the authorized number of directors,  but in no event less
than three  (3),  shall  constitute  a quorum for the  transaction  of  busines;
except,  however, to adjourn a meeting at which a quorum is present, the vote of
a majority of the directors present shall be regarded as the act of the Board of
Directors,  unless the vote of a greater number is required by law, the Articles
of Incorporation, or these By-Laws.

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

Section 24.  Contents of Notice and Waiver of Notice.
         Neither  the  business  to be  transacted  at, nor the  purpose of, any
regular or special  Board  meeting  need be specified in the notice or waiver of
notice of the meeting. Notice of a meeting need not be given to any director who
signs a waiver of notice 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 the lack of notice to said  director,  either prior
thereto or at its commencement.  All such waivers, consents, and approvals shall
be  filed  with  the  corporate  records  or made a part of the  minutes  of the
meeting.

Section 25.  Adjournment.
         A  majority  of the  directors  present,  whether  or not a  quorum  is
present, may adjourn any meeting to another time and place.

Section 26.  Notice and Adjournment.
         Notice of the time and place of holding an  adjourned  meeting need not
be given to absent  directors  if the time and  place  are fixed at the  meeting
being adjourned, except that if the meeting is adjourned for more than 24 hours,
such notice shall be given prior to the adjourned meeting,  to the directors who
were not present at the time of the adjournment.

Section 27.  Telephone Participation.
         Members  of the  Board may  participate  in a  meeting  through  use of
conference telephone or similar communications equipment, so long as all members
participating  in  such  meetings  can  hear  one  another.  Such  participation
constitutes presence in person at such meeting.

Section 28.  Action without Meeting.
         The Board of Directors  may take any action  without a meeting that may
be required or permitted  to be taken by the Board at a meeting,  if all members
of the Board,  individually or  collectively,  consent in writing to the action.
The written consent or consents shall be filed in the minutes of the proceedings
of the Board.  Such action by written  consent  shall have the same effect as an
unanimous vote of directors.

Section 29.  Fees and Compensation.
         Directors and members of committees shall receive neither  compensation
for their services nor  reimbursement  for their expenses,  unless such payments
are fixed by resolution of the Board.

the Board.

                            General Corporate Matters

Section 41.  Record Date and Closing of Stockbooks.
         The Board of  Directors  may fix a time in the future as a record  date
for  determining  shareholders  entitled  to  notice  of  and  to  vote  at  any
shareholders'  meeting; to receive any dividend,  distribution,  or allotment of
rights;  or to exercise rights in respect of any other lawful action,  including
change,  conversion,  or exchange of shares. The record date shall not, however,
be more than  sixty  (60) nor less than ten (10) days  prior to the date of such
meeting  nor more than sixty (60) days  prior to any other  action.  If a record
date is fixed for a particular  meeting or event, only shareholders of record on
that  date are  entitled  to notice  and to vote and to  receive  the  dividend,
distribution,  or allotment of rights or to exercise the rights, as the case may
be,  notwithstanding  any transfer of any share on the books of the  corporation
after the record date.

          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  fixes a new record  date for the  adjourned  meeting,  but the
Board shall fix a new record date if the meeting is  adjourned  for more than 45
days.

Section 42.  Corporate Books and Inspection by Shareholders and Directors.
          Books and  records of account and  minutes of the  proceedings  of the
shareholders,  Board,  and committees of the Board,  shall be kept available for

and class of shares held by each,  shall be kept available for inspection at the
principal  office  or at the  office  of the  corporation's  transfer  agent  or
registrar.

          A shareholder  or  shareholders  holding at least five percent (5%) in
the aggregate of the outstanding  voting shares of the corporation shall have an
absolute right to do either or both of the  following:  (1) inspect and copy the
record of  shareholders'  names and  addresses  and  shareholdings  during usual
business   hours  upon  five  business  days'  prior  written  demand  upon  the
corporation,  or (2) obtain from the transfer  agent 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 for which it has been
compiled or as of a date specified by the shareholder  subsequent to the date of
demand.  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.  Inspection  and copying may be made in person or by
agent or attorney.

          Every director shall have the absolute right at any reasonable time to
inspect and copy all books,  records and documents of every kinds and to inspect
the physical  properties of the  corporation  and its  subsidiary  corporations,
domestic or foreign.  Such inspection by a director may be in person or by agent
or attorney and includes the right to copy and make extracts.

Section 43.  Checks, Drafts, Evidences of Indebtedness.
         All checks,  drafts,  or other orders for payment of money,  notes, and
all  mortgages,  or other  evidences of  indebtedness,  issued in the name of or
payable  to  the  corporation,  and  all  assignments  and  endorsements  of the
foregoing,  shall be signed or  endorsed  by the  person or  persons  and in the
manner specified by the Board of Directors.

Section 44.  Corporate Contracts and Instruments; How Executed.
         Except as  otherwise  provided in the  By-Laws,  officers,  agents,  or
employees  must be  authorized  by the  Board of  Directors  to  enter  into any
contract or execute any instrument in the corporation's  name and on its behalf.
This authority may be general or confined to specific instances.

Section 45.  Stock Certificates.
          One or more certificates for shares of the corporation's capital stock
shall be issued to each shareholder for
                                      -9-

any of his shares that are fully paid up. The  corporate  seal or its  facsimile
may be fixed on certificates.  All certificates  shall be signed by the Chairman
of the Board, President/CEO,  or a Vice President and the Secretary,  Treasurer,
or an Assistant  Secretary.  Any or all of the signatures on the certificate may
be facsimile signatures.

Section 46.  Lost Certificates.
         No new  share  certificate  that  replaces  an old one  shall be issued
unless the old one is  surrendered  and  cancelled  at the same time;  provided,
however, that if any share certificate is lost, stolen, mutilated, or destroyed,
the Board of Directors may authorize issuance of a new certificate replacing the
old one on any terms and  conditions,  including a  reasonable  arrangement  for
indemnification of the corporation, that the Board may specify.

Section 47.  Reports to Shareholders.
         The requirement  for the annual report to  shareholders  referred to in
Section 1501(a) of the California  Corporations  Code is hereby expressly waived
so long as there  are less  than 100  holders  of  record  of the  corporation's
shares.  The Board of Directors shall cause to be sent to the shareholders  such
annual or other  periodic  reports as they consider  appropriate or as otherwise
required by law.  In the event the  corporation  has 100 or more  holders of its
shares,  an annual report  complying with Section 1501(a) and, when  applicable,
Section 1501(b) of the  Corporations  Code shall be sent to the shareholders not
later than 120 days after the close of the fiscal year and at least fifteen (15)
days prior to the  annual  meeting of  shareholders  to be held  during the next
fiscal year.

          If no  annual  report  for the  last  fiscal  year  has  been  sent to
shareholders, the corporation shall, upon the written request of any shareholder
made more than 120 days after the close of such fiscal year,  deliver or mail to
the person making the request within 30 days thereafter the financial statements
referred to in Section 1501(a) for such year.

          A shareholder  or  shareholders  holding at least five percent (5%) of
the outstanding  shares of any class of a corporation may make a written request
to  the  corporation  for  an  income  statement  of  the  corporation  for  the
three-month sixmonth, or nine-month period of the current fiscal year ended more
than 30 days  prior  to the  date of the  request  and a  balance  sheet  of the
corporation  as of the end of such period and, in addition,  if no annual report
for the last fiscal year has been sent to shareholders,  the statements referred
to in Section  1501(a) of the  Corporations  Code for the last fiscal year.  The
statement  shall be  delivered or mailed to the  shareholder  making the request
within 30 days thereafter. A copy of the statements shall be kept on file in the
principal  office of the  corporation  for twelve  (12) months and they shall be
exhibited at all reasonable times to any shareholder demanding an examination of
them or a copy shall be mailed to such  shareholder.  The income  statements and
balance sheets referred to shall be accompanied by the report  thereon,  if any,
of any independent  accountants engaged by the corporation or the certificate of
an authorized  officer of the  corporation  that such financial  statements were
prepared without audit from the books and records of the corporation.

Section 48.  Indemnity of Officers and Directors.
          The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any  proceeding  (other than an action by or in
the right of the  corporation  to procure a judgment  in its favor) by reason of
the  fact  that  such  person  is or was an agent  of the  corporation,  against
expenses,   judgments,   fines,  settlements  and  other  amounts  actually  and
reasonably incurred in connection with such proceeding,  if such person acted in
good faith and in a manner  such  person  reasonably  believed to be in the best
interest of the corporation  and, in the case of a criminal  proceeding,  had no
reasonable  cause to believe  the  conduct  of such  person  was  unlawful.  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 the
person reasonably believed to be in the best interest of the corporation or that
the person  had  reasonable  cause to  believe  that the  person's  conduct  was
unlawful.

         The corporation  shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened,  pending or completed action by
or in the right of the  corporation to procure a judgment in its favor by reason
of the fact that  such  person  is or was an agent of the  corporation,  against
expenses actually and reasonably  incurred by such person in connection with the
defense or  settlement  of such action if such person acted in good faith,  in a
manner such person  believed to be in the best interests of the  corporation and
with such care including reasonable

                                      -10-

inquiry,  as an ordinarily  prudent  person in a like  position  would use under
similar circumstances; except that no indemnification shall be made:

         (1) In respect of any  claim,  issue or matter as to which such  person
shall have been adjudged to be liable to the corporation  during the performance
of such person's duty to the corporation, unless and only to the extent that the
court  in  which  such  proceeding  is  or  was  pending  shall  determine  upon
application  that, in view of all the  circumstances of the case, such person is
fairly and reason- ably  entitled to indemnity for the expenses such court shall
determine;

          (2) Of amounts paid in settling or otherwise disposing of a threatened
or pending action, with or without court approval; or

         (3) Of expenses  incurred in defending a threatened  or pending  action
which is settled or otherwise disposed of without court approval.

         Any  indemnification  under  this  Section  47  shall  be  made  by the
corporation  only if authorized in the specific case, upon a determination  that
indemnification  of the agent is proper in the  circumstances  because the agent
has met the applicable standard of conduct by:

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

         (2) Approval of the  shareholders by the affirmative vote of a majority
of the shares  entitled to vote  represented  at a duly held  meeting at which a
quorum is present or by the  written  consent of  shareholders  as  provided  in
Section  10,  with the shares  owned by the person to be  indemnified  not being
entitled to vote thereon.

         Upon written  request of an agent  seeking  indemnification  under this
Section,  the Board by majority vote shall promptly make a determination in good
faith as to  whether  the  applicable  standard  of conduct  has been met.  If a
positive determination is made, indemnification shall be authorized forthwith if
the  directors  approving  the  determination  include a majority of a quorum of
directors not parties to the proceeding, otherwise the question of authorization
by the shareholders shall be put to a shareholder vote no later than the date of
the next annual  meeting and said question  shall be included in any  management
proxy solicitation for or prior to said meeting.  Expenses incurred in defending
any  proceeding  shall  be  advanced  by the  corporation  prior  to  the  final
disposition of such proceeding upon receipt of an undertaking by or on behalf of
the agent to repay such amount unless it shall be determined ultimately that the
agent is entitled to be indemnified as authorized in this Section.

         For the purposes of this  Section,  "agent"  means any person who is or
was a director,  officer,  employee or other agent of the corporation,  or is or
was serving at the request of the corporation as a director,  officer,  employee
or agent,  of  another  foreign  or  domestic  corporation,  partnership,  joint
venture,  trust or other  enterprise,  or was a director,  officer,  employee or
agent of a foreign or domestic corporation which was predecessor  corporation of
the  corporation  or of another  enterprise  at the request of such  predecessor
corporation;  "proceeding" means any threatened,  pending or completed action or
proceeding,  whether  civil,  criminal,  administrative  or  investigative;  and
"expenses"  includes  without  limitation  attorneys'  fees and any  expenses of
establishing a right to indemnification.

                                   Amendments

Section 49.  Amendment by Shareholders.
         By-Laws may be adopted,  amended or repealed by the affirmative vote or
written  consent of a  majority  of the  outstanding  shares  entitled  to vote;
provided,  however,  that an  amendment  to  Section 15  reducing  the number of
directors  on a  fixed-number  board or the  minimum  number of  directors  on a
variable-number  board to a number less than five cannot be adopted if the votes
cast against its adoption at a meeting or the shares not consenting, in the case
of action by  written  consent,  are equal to more than  16-2/3  percent  of the
outstanding shares entitled to vote.


                                      -11-

Section 50.  Amendment by Directors.
         Subject to the right of  shareholders  under the preceding  Section 49,
By-Laws, may be adopted, amended, or repealed by the Board of Directors,  except
that  only the  shareholders  can  adopt a by-law  or  amendment  thereto  which
specifies  or changes the number of directors on a  fixed-number  Board,  or the
minimum or maximum  number of directors  on a  variable-number  Board,  or which
changes from a fixed-number Board to a variable-number Board or vice versa.

                             Committees of the Board

Section 51.  Committees of the Board.
         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 or more  directors,  to serve at the pleasure of the Board and
with  such  authority  and  organization  as the  Board  may  from  time to time
determine. The Board may designate one or more directors as alternate members of
any  committee,  who  may  replace  any  absent  member  at any  meeting  of the
committee.  The  appointment  of members  or  alternate  members of a  committee
requires the vote of a majority of the authorized number of directors.  Any such
committee requires the vote of a majority of the authorized number of directors,
and any such  committee,  to the extent provided in the resolution of the Board,
shall have all the authority of the Board, except with respect to:

         (1)      The approval of any action for which shareholder approval is
also required.
         (2)      The filling of vacancies on the Board or in any committee.
         (3)      The fixing of compensation of the directors for serving on the
        Board or on any committee.
         (4)      The amendment or repeal of By-Laws or the adoption of By-Laws.
         (5)      The amendment or repeal of any resolution of the Board which
by its express terms is not so amendable or repealable.
         (6) A distribution to the shareholders of the corporation as defined in
Section 166 of the Corporations  Code,  except at a rate or in a periodic amount
or within a price range determined by the Board.
         (7)      The appointment of other committees of the Board or the
members thereof.

         The Board shall  designate a chairman for each committee who shall have
the sole power to call any  committee  meeting  other than a meeting  set by the
Board.  Except as  otherwise  established  by the  Board,  Article  III of these
By-Laws shall apply to committees of the Board and action by such committees.
