     Section 1.  Principal Executive Office.  The principal executive office of
                 --------------------------

Directors shall by resolution determine.  The Board of Directors is hereby

                                  ARTICLE II

                           Meetings of Shareholders

     Section 1.  Place of Meetings.  All annual or other meetings of
                 -----------------                                  
Shareholders shall be held at the principal executive office of the corporation,
or at any other place within or without the State of California which may be
designated either by the Board of Directors or by the written consent of all
persons entitled to vote thereat and not present at the meeting, given either
before or after the meeting and filed with the Secretary of the corporation.

     Section 2.  Annual Meetings.  The annual meetings of Shareholders shall be
                 ---------------                                               
held on the first Monday of February of each year at 11 a.m. or at such other
date or time as may be set by the Board. At such meetings, Directors shall be
elected, reports of the affairs of the corporation shall be considered, and any
other business may be transacted which is within the powers of the Shareholders.

     Written notice of each annual meeting of Shareholders shall be given either
(i) personally or (ii) by first-class mail or (iii) by third-class mail but only
if the corporation has outstanding shares held of record by five hundred (500)
or more persons (determined as provided in Section 605 of the Code) on the
record date for the Shareholders' meeting, or (iv) by telegraphic or other
written communication.  Notices not personally delivered shall be sent charges
prepaid and shall be addressed to the Shareholder at the address of that
Shareholder appearing on the books of the corporation or given by the
Shareholder to the corporation for the purpose of notice.  If no such address
appears on the corporation's books or is given, notice shall be deemed to have
been 

 
given if sent to that Shareholder by mail or telegraphic or other written
communication to the corporation's principal executive office, or if published
at least once in a newspaper of general circulation in the county where that
office is located. Notice shall be deemed to have been given at the time when
delivered personally or deposited in the mail or sent by telegram or other means
of written communication.

     If any notice addressed to a Shareholder at the address of that Shareholder
appearing on the books of the corporation is returned to the corporation by the
United States Postal Service marked to indicate that the United States Postal
Service is unable to deliver the notice to the Shareholder at that address, then
all future notices or reports shall be deemed to have been duly given without
further mailing if the same shall be available to the Shareholder on written
demand of the Shareholder at the principal executive office of the corporation
for a period of one (1) year from the date of the giving of the notice.

     An affidavit of the mailing or other means of giving any notice of any
Shareholders' meeting, executed by the Secretary, Assistant Secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
                                                              -----------
evidence of the giving of such notice.
 
     Such notices shall specify:

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

          (b)  those matters which the Board, at the time of the mailing of the
notice, intends to present for action by the Shareholders;

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

          (d)  the general nature of a proposal, if any, to take action with
respect to approval of (i) a contract or transaction in which a Director has a
direct or indirect financial interest, pursuant to Section 310 of the
Corporations Code of California (the "Code"), (ii) an amendment of the Articles
of Incorporation, pursuant to Section 902 of the Code, (iii) a reorganization of
the corporation, pursuant to Section 1201 of the Code, (iv) a voluntary
dissolution of the corporation, pursuant to Section 1900 of the Code, or (v) a
distribution in dissolution other than in accordance with the rights of
outstanding preferred shares, pursuant to Section 2007 of the Code; and

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

     Section 3.  Special Meetings. Special meetings of the Shareholders, for the
                 ----------------                                               
purpose of taking any action permitted by the Shareholders under the General
Corporation Law and the Articles of Incorporation of this corporation, may be
called at anytime by the Chairman of the 

                                      -2-

 
Board or the President, or by the Board of Directors, or by one or more
Shareholders holding not less than ten percent of the votes at the meeting. Upon
request in writing that a special meeting of Shareholders be called for any
proper purpose, directed to the Chairman of the Board, President, Executive Vice
President, or Secretary by any person (other than the Board) 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 thirty-
five (35) nor more than sixty (60) days after receipt of the request. Except in
special cases where other express provision is made by statute, notice of such
special meetings shall be given in the same manner as for annual meetings of
Shareholders. If the notice is not given within twenty (20) days after receipt
of the request, then the person or persons requesting the meeting may give the
notice. In addition to the matters required by items (a) and, if applicable, (c)
of the preceding Section, notice of any special meeting shall specify the
general nature of the business to be transacted, and no other business may be
transacted at such meeting.

     Section 4.  Quorum.  The presence in person or by proxy of the persons
                 ------                                                    
entitled to vote a majority of the voting shares at any meeting shall constitute
a quorum for the transaction of business. The Shareholders present at a duly
called or held meeting at which a quorum is present may continue to do business
until adjournment, notwithstanding the withdrawal of enough Shareholders to
leave less than a quorum, if any action taken (other than adjournment) is
approved by at least a majority of the shares required to constitute a quorum.

     Section 5.  Adjourned Meeting and Notice Thereof.  Any Shareholders'
                 ------------------------------------                    
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the vote of a majority of the shares, the holders of which
are either present in person or represented by proxy thereat, but in the absence
of a quorum, no other business may be transacted at such meeting, except as
provided in Section 4 above.

     When any Shareholders' meeting, either annual or special, is adjourned for
forty-five (45) days or more, or if after adjournment a new record date is fixed
for the adjourned meeting, notice of the adjourned meeting shall be given as in
the case of an original meeting.  Except as provided above, it shall not be
necessary to give any notice of the time and place of the adjourned meeting or
of the business to be transacted thereat, other than by announcement of the time
and place thereof at the meeting at which such adjournment is taken.

     Section 6.  Voting.  Unless a record date for voting purposes be fixed as
                 ------                                                       
provided in Section 1 of Article V of these Bylaws, then, subject to the
provisions of sections 702 through 704, inclusive, of the Code (relating to
voting of shares held by a fiduciary, in the name of a corporation, or in joint
ownership), only persons in whose names shares entitled to vote stand on the
stock records of the corporation at the close of business on the business day
next preceding the day on which notice of the meeting is given or, if such
notice is waived, at the close of business on the business day next preceding
the day on which the meeting of Shareholders is held, shall be 

                                      -3-

 
entitled to vote at such meeting, and such day shall be the record date for such
meeting. Such vote may be viva voce or by ballot; provided, however, that all
                          ---------
elections for Directors must be by ballot upon demand made by a Shareholder at
any election and before the voting begins. If a quorum is present, except with
respect to election of Directors, the affirmative vote of the majority of the
shares represented at the meeting and entitled to vote on any matter shall be
the act of the Shareholders, unless the vote of a greater number or voting by
classes is required by the Code or the Articles of Incorporation. Any
Shareholder entitled to vote on any matter may vote part of the shares in favor
of the proposal and refrain from voting the remaining shares or, except when the
matter is the election of Directors, may vote them against the proposal; but, if
the Shareholder fails to specify the number of shares which the Shareholder is
voting affirmatively, it will be conclusively presumed that the Shareholder's
approving vote is with respect to all shares which the Shareholder is entitled
to vote. Subject to the requirements of the next sentence, every Shareholder
entitled to vote at any election for Directors shall have the right to cumulate
his votes and give one candidate a number of votes equal to the number of
Directors to be elected multiplied by the number of votes to which his shares
are entitled, or to distribute his votes on the same principle among as many
candidates as he shall think fit. No Shareholder shall be entitled to cumulative
votes unless the name of the candidate or candidates for whom such votes would
be cast has been placed in nomination prior to the voting and any Shareholder
has given notice at the meeting prior to the voting of such Shareholder's
intention to cumulate his votes. The candidates receiving the highest number of
votes of shares entitled to be voted for them, up to the number of Directors to
be elected, shall be elected; votes against any candidate and votes withheld
shall have no legal effect.

     Section 7.  Validation of Defectively Called or Noticed Meetings.  The
                 ----------------------------------------------------      
transactions of any meeting of Shareholders, either annual or special, however
called and noticed, shall be as valid as though had at a meeting duly held after
regular call and notice, if a quorum be present either in person or by proxy,
and if, either before or after the meeting, each of the persons entitled to
vote, not present in person or by proxy, or who, though present, has, at the
beginning of the meeting, properly objected to the transaction of any business
because the meeting was not lawfully called or convened, or to particular
matters of business legally required to be included in the notice, but not so
included, signs a written waiver of notice, or a consent to the holding of such
meeting, or an approval of the minutes thereof.  The waiver of notice or consent
or approval need not specify either the business to be transacted or the purpose
of any annual or special meeting of Shareholders, except that if action is taken
or proposed to be taken for approval of any of those matters specified in
Section 2 of Article II of these Bylaws, the waiver of notice or consent or
approval shall state the general nature of the proposal.  All such waivers,
consents, or approvals shall be filed with the corporate records or made a part
of the minutes of the meets.

     Section 8.  Action Without Meeting.  Directors may be elected without a
                 ----------------------                                     
meeting by a consent in writing, setting forth the action so taken, signed by
all of the persons who would be entitled to vote for the election of Directors,
provided that, without notice except as hereinafter set forth, a Director may be
elected at any time to fill a vacancy not filled by the Directors by the 

                                      -4-

 
written consent of persons holding a majority of the outstanding shares entitled
to vote for the election of Directors.

     Any other action which, under any provision of the California General
Corporation Law may be taken at a meeting of the Shareholders, may be taken
without a meeting, and without notice except as hereinafter set forth, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take such action at a meeting at which all
shares entitled to vote thereon were present and voted.  Unless the consents of
all Shareholders' entitled to vote have been solicited in writing,

          (a)  Notice of any proposed Shareholder approval of (i) a contract or
other transaction with an interested Director, (ii) indemnification of an agent
of the corporation as authorized by Section 15 of Article III of these Bylaws,
(iii) a reorganization of the corporation as defined in section 181 of the Code,
or (iv) a distribution in dissolution other than in accordance with the rights
of outstanding preferred shares, if any, without a meeting by less than
unanimous written consent, shall be given at least ten (10) days before the
consummation of the action authorized by such approval; and

          (b)  Prompt notice shall be given of the taking of any other corporate
action approved by Shareholders without a meeting by less than unanimous written
consent, to those Shareholders entitled to vote who have not consented in
writing.  Such notices shall be given in the manner and shall be deemed to have
been given as provided in Section 2 of Article II of these Bylaws.

     Unless, as provided in Section 1 of Article V of these Bylaws, the Board of
Directors has fixed a record date for the determination of Shareholders entitled
to notice of and to give such written consent, the record date for such
determination (i) when no prior action by the Board has been taken, shall be the
day on which the first written consent is given, or (ii) when prior action by
the Board has been taken, shall be at the close of business on the day on which
the Board adopts the resolution relating to that action, or the sixtieth (60th)
day before the date of such other action, whichever is later.

     Any Shareholder giving a written consent, or the Shareholder's
proxyholders, or a transferee of the shares or a personal representative of the
Shareholder or their respective proxyholders, may revoke the consent by a
writing received by the corporation prior to the time 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 9.  Proxies.  Every person entitled to vote for Directors, or on
                 -------                                                     
any other matter, shall have the right to do so either in person or by one or
more agents authorized by a written 

                                      -5-

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

     Section 10. Inspectors of Election.  In advance of any meeting of
                 ----------------------                               
Shareholders, the Board of Directors may appoint any persons other than nominees
for office as inspectors of election to act at such meeting or any adjournment
thereof.  If inspectors of election be not so appointed, the Chairman of any
such meeting may, and on the request of any Shareholder or his proxy shall, make
such appointment at the meeting.  The number of inspectors shall be either one
(1) or three (3).  If appointed at a meeting on the request of one or more
Shareholders or proxies, the majority of shares represented in person or by
proxy shall determine whether one (1) or three (3) inspectors are to be
appointed.  In case any person appointed as inspector fails to appear or fails
or refuses to act, the vacancy may, and on the request of any Shareholder or a
Shareholder's proxy shall, be filled by appointment by the Board of Directors in
advance of the meeting, or at the meeting by the Chairman of the meeting.

     The duties of such inspectors shall be as prescribed by section 707 of the
General Corporation Law and shall include: determining 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; receiving votes, ballots, or consents; hearing and determining all
challenges and questions in any way arising in connection with the right to
vote; counting and tabulating all votes or consents; determining when the polls
shall close; determining the result; and such acts as may be proper to conduct
the election or vote with fairness to all Shareholders.  In the determination of
the validity and effect of proxies, the dates contained on the forms of proxy
shall presumptively determine the order of execution of the proxies, regardless
of the postmark dates on the envelopes in which they are mailed.

     The inspectors of election shall perform their duties impartially, in good
faith, to the best of their ability, and as expeditiously as is practical.  If
there are three (3) inspectors of election, the decision, act, or certificate of
a majority is effective in all respects as the decision, act, or certificate of
all.  Any report of certificate made by the inspectors of election is prima
                                                                      -----

                                   Directors

          Section 1.  Powers.  Subject to the provisions of the Code and any
                      ------                                                
limitations in the Articles of Incorporation and these Bylaws relating to action
required to be approved by the Shareholders or by the outstanding 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.

          Section 2.  Number and Qualification of Directors.  The authorized
                      -------------------------------------                 
number of Directors shall be no fewer than four (4) no more than seven (7).  The
exact number of authorized Directors shall be seven (7) until changed, within
the limits specified above, by a Bylaw amending this section, duly adopted by
the Board of Directors or by the Shareholders.  The indefinite number of
Directors may be changed, or a definite number may be fixed without provision
for an indefinite number, by a duly adopted amendment to the Articles of
Incorporation or by an amendment to this Bylaw duly adopted by the vote or
written consent of holders of a majority of the outstanding shares entitled to
vote; provided, however, that an amendment reducing the fixed number or the
minimum number of Directors to a number less than five (5) cannot be adopted if
the votes cast against its adoption at a meeting, or the shares not consenting
in the case of an action by written consent, are equal to more than sixteen and
two-thirds percent (16-2/3%) of the outstanding shares entitled to vote thereon.
No amendment may change the stated maximum number of authorized Directors to a
number greater than two (2) times the stated minimum number of Directors minus
one (1).

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

          Section 3.  Election and Term of Office.  The Directors shall be
                      ---------------------------                         
elected at each annual meeting of Shareholders, but if any such annual meeting
is not held or the Directors are not elected thereat, the Directors may be
elected at any special meeting of Shareholders held for that purpose. All
Directors shall hold office until their respective successors are elected,
subject to the General Corporation Law and the provisions of these Bylaws with
respect to vacancies on the Board.

          Section 4.  Vacancies.  A vacancy or vacancies in the Board of
                      ---------                                         
Directors shall be deemed to exist (i) in the event of the death, resignation or
removal of any Director, (ii) if the Board of Directors by resolution declares
vacant the office of a Director who has been declared of unsound 

                                      -7-

 
mind by an order of court or convicted of a felony, (iii) if the authorized
number of Directors is increased, or (iv) if the Shareholders fail, at any
meeting of Shareholders at which any Director or Directors are elected, to elect
the number of Directors to be elected at that meeting.

          Vacancies in the Board of Directors, except for 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, and each
Director so elected shall hold office until his successor is elected at an
annual or a special meeting of the Shareholders. A vacancy in the Board of
Directors created by the removal of a Director may only be filled by the vote of
a majority of the shares entitled to vote represented at a duly held meeting at
which a quorum is present, or by the unanimous written consent of the holders of
all outstanding shares entitled to vote.

          The Shareholders may elect a Director or Directors at any time to fill
an vacancy or vacancies not filled by the Directors.  Any such election by
written consent shall require the consent of holders of a majority of the
outstanding shares entitled to vote.

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

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

          Section 5.  Place of Meeting.  Regular meetings of the Board of
                      ----------------                                   
Directors shall take place within or without the state which has from time to
time by resolution of the Board or by written consent of all members of the
Board.  In the absence of such designation, regular meetings shall be held at
the principal executive office of the corporation.  Special meetings of the
Board may be held either at a place so designated or at the principal executive
office.

          Section 6.  Organization Meetings.  Immediately following each annual
                      ---------------------                                    
meeting of Share holders, the Board of Directors shall hold a regular meeting at
the place of said annual meeting, or at such other place as shall be fixed by
the Board of Directors, for the purpose of organization, election of Officers,
and the transaction of other business.  Call and notice of such meetings are
hereby dispensed with.

          Section 7.  Other Regular Meetings.  Other regular meetings of the
                      ----------------------                                
Board of Directors shall be held without call at such times and places as
determined by the Board of Directors by resolution duly adopted.  Notice of all
such regular meetings of the Board of Directors hereby dispensed with.

          Section 8.  Special Meetings.  Special meetings of the Board of
                      ----------------                                   
Directors for any purpose or purposes shall be called at any time by the
Chairman of the Board, the President, the Executive Vice President, or by any
two (2) Directors.

          Written notice of the time and place of special meetings shall be
delivered personally to each Director or communicated to each Director by
telephone, or by telegraph or mail, charges prepaid, addressed to him at his
address as it is shown upon the records of the corporation or, if it is not so
shown on such records or is not so shown upon the records of the corporation or,
if it is not, at the place at which the meetings of the Directors are regularly
held.  In case such notice is mailed or telegraphed, it shall be deposited in
the United States mail or delivered to the telegraph company in the place in
which the principal executive office of the corporation is located at least four
(4) days prior to the time of the holding of the meeting. In case such notice is
delivered, personally or by telephone, as above provided, it shall be so
delivered at least forty-eight (48) hours prior to the time of the holding of
the meeting. Such mailing, telegraphing, or delivery, personally or by

Directors may be taken without a meeting if all members of the Board shall
individually or collectively consent in writing to such action.  Such written

Directors constitutes a quorum for the transaction of business, except as

meeting as permitted in the preceding sentence constitutes presence in person at
such meeting.  Every act or decision done or made by a majority of the Directors
present at a duly held meeting at which a quorum is present shall be regarded as
the act of the Board of Directors, subject to the provisions of Section 310 of

direct or indirect material financial interest), Section 311 of the Code (as to
appointment of committees), Section 317(e) of the Code (as to indemnification of

meeting of the Board of Directors, however called and noticed or wherever held,
shall be as valid as though had at a meeting duly held after regular call and
notice, if a quorum is present and if, either before of after the meeting, each
of the Directors not present or who, though present, has, prior to the meeting
or at its commencement, protested the lack of proper notice to him, signs a
written waiver of notice or a consent to holding such meeting or an approval of
the minutes thereof. All such waivers, consents, or approvals shall be filed
with the corporate records or made a part of the minutes of the meeting.

reimbursement for expenses, as may be fixed or determined by resolution of the
Board.  This Section 14 shall not be construed to preclude any Director from
serving the corporation in any other capacity as an officer, agent, employee or
otherwise and receiving compensation for those services.

permitted by the Code, indemnify each of its Directors and officers against
expenses (as defined in Section 317(a) of the Code), judgments, fines,
settlements, and other amounts actually and reasonably incurred in connection
with any proceeding (as defined in Section 317(a) of the Code), arising by

purposes of this Section 15, a "Director" or "officer" of the corporation
includes any person (i) who is or was a Director or officer of the corporation,
(ii) who is or was serving at the request of the corporation as a Director or
officer of another corporation, partnership, joint venture, trust or other
enterprise, or (iii) who was a Director or officer of a corporation which was a
predecessor corporation of the corporation or of another enterprise at the
request of such predecessor corporation.

          (b) The corporation shall have the power, to the extent and in the
manner permitted by the Code, to indemnify each of its employees and agents
(other than Directors and officers) against expenses (as defined in Section
317(a) of the Code), judgments, fines, settlements, and other 

                                      -10-

 
amounts actually and reasonably incurred in connection with any proceeding (as
defined in Section 317(a) of the Code), arising by reason of the fact that such
person is or was an agent of the corporation. For purposes of this Section 15,
an "employee" or "agent" of the corporation (other than a Director or officer)
includes any person (i) who is or was an employee or agent of the corporation,
(ii) who is or was serving at the request of the corporation as an employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, or (iii) who was an employee or agent of a corporation which was a
predecessor corporation of the corporation or of another enterprise at the
request of such predecessor corporation.

          (c) Expenses incurred in defending any civil or criminal action or
proceeding for which indemnification is required pursuant to Section 15(a) or
for which indemnification is permitted pursuant to Section 15(b) following
authorization thereof by the Board of Directors shall be paid by the corporation
in advance of the final disposition of such action or proceeding upon receipt of
an undertaking by or on behalf of the indemnified party to repay such amount if
it shall ultimately be determined that the indemnified party is not entitled to
be indemnified as authorized in this Section 15.

          (d) The indemnification provided by this Section 15 shall not be
deemed exclusive of any other rights to which those seeking indemnification may
be entitled under any Bylaw, agreement, vote of Shareholders or disinterested
Directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the Articles of
Incorporation.

          (e) The corporation shall have the power to purchase and maintain
insurance on behalf of any person who is or was a Director, officer, employee or
agent of the corporation against any liability asserted against or incurred by
such person in such capacity or arising out of such person's status as such,
whether or not the corporation would have the power to indemnify him against
such liability under the provisions of this Section 15.

          (f) No indemnification or advance shall be made under this Section 15,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

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

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

on file in the principal executive 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 corporation shall, upon the written request of any Shareholder,
mail to the Shareholder a copy of the last annual, semiannual, or quarterly
income statement which it has prepared and a balance sheet as of the end of the
period.  The quarterly income balance sheets referred to in this section shall
be accompanied by the report thereon, if any, of any dependent 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 5.  Contracts, Etc., How Executed.  The Board of Directors,
                      -----------------------------                          
except as in the 

                                      -17-

 
Bylaws otherwise provided, may authorize any Officer or Officers, agent or
agents, to enter into any contract or execute any instrument in the name of and
on behalf of the corporation, and such authority may be general or confined to
specific instances; and, unless so authorized or ratified by the Board of
Directors, no Officer, agent, or employee shall have any power or authority to
bind the corporation by any contract or engagement or to pledge its credit or to
render it liable for any purpose or to any amount.

          Section 6.  Certificate for Shares.  Every holder of shares in the
                      ----------------------                                
corporation shall be entitled to have a certificate signed in the name of the
corporation by the Chairman or Vice Chairman of the Board or the president or
the Executive Vice President and by the Chief Financial Officer or an Assistant
Chief Financial Officer or the secretary or any Assistant secretary, certify the
number of shares and the class or series of shares owned by the Shareholder. In
case any Officer, transfer agent, or registrar who has signed 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. Any or all of the signatures on the certificate may be facsimile.

          Certificates for shares may be issued prior to full payment under such
restrictions and for such purposes as the Board of Directors or the Bylaws may
provide; provided, however, that any such certificate so issued prior to full
payment shall state on the face thereof the amount remaining unpaid and the
terms of payment thereof.

          No new certificate for shares shall be issued in lieu of an old
certificate unless the latter is surrendered and cancelled at the same time;
provided, however, that a new certificate will be issued without the surrender
and cancellation of the old certificate if (1) the old certificate is lost,
apparently destroyed, or wrongfully taken; (2) the request for the issuance of
the new certificate is made within a reasonable time after the owner of the old
certificate has notice of its loss, destruction, or theft; (3) the request for
the issuance of a new certificate is made prior to the receipt of notice by the
corporation that the old certificate has been acquired by a bona fide purchaser;
(4) the owner of the old certificate files a sufficient indemnity bond with or
provides other adequate security to the corporation; and (5) the owner satisfies
any other reasonable requirements imposed by the corporation.  In the event of
the issuance of a new certificate, the rights and liabilities of the
corporation, and of the holders of the old and new certificates, shall be
governed by the provisions of sections 9104 and 9405 of the California
Commercial Code.

          Section 7.  Representation of Shares of Other Corporations.  The
                      ----------------------------------------------      
President, the Chairman of the Board, or the Executive Vice President and the
Secretary or any Assistant Secretary of this corporation are authorized to vote,
represent, and exercise on behalf of this corporation all rights incident to any
and all shares of any other corporation or corporations standing in the name of
this corporation.  The authority herein granted to said Officers to vote or
represent on behalf of this corporation any and all shares held by this
corporation in any other corporation or corporations may be exercised either by
such Officers in person or by any other person authorized so to do by 

                                      -18-

 
proxy or power of attorney duly executed by said Officers.

          Section 8.  Inspection of Bylaws.  The corporation shall keep in its
                      --------------------                                    
principal executive office in California, or if its principal executive office
is not in California, then at its principal business office in California (or
otherwise provide upon written request of any Shareholder), the original or a
copy of the Bylaws as amended or otherwise altered to date, certified by the
Secretary, which shall be open to inspection by the Shareholders at all
reasonable times during office hours.

          Section 9.  Construction and Definitions.  Unless the context
                      ----------------------------                     
otherwise requires, the general provisions, rules of construction, and
definitions contained in the California General Corporation Law shall govern the
construction of these Bylaws. Without limiting the generality of the foregoing,
the masculine gender includes the feminine and neuter, the singular number
includes the plural and the plural number includes the singular, and the term
"person" includes a corporation as well as a natural person.
