                               CORPORATE OFFICES
                               -----------------

     1.1  PRINCIPAL OFFICE
          ----------------

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

     1.2  OTHER OFFICES
          -------------

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

                            MEETINGS OF SHAREHOLDERS
                            ------------------------

     2.1  PLACE OF MEETINGS
          -----------------

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

     2.2  ANNUAL MEETING
          --------------

     The annual meeting of shareholders shall be held each year within 180 days
following the end of the fiscal year of the Corporation at a date and time
designated by the Board of Directors.  However, if such day falls on a legal
holiday, then the meeting shall be held at the same time and place on the next
succeeding full business day.  At the meeting, directors shall be elected, and
any other proper business may be transacted.
<PAGE>
 
     2.3  SPECIAL MEETING
          ---------------

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

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

     2.4  NOTICE OF SHAREHOLDERS' MEETINGS  
          --------------------------------   

     All notices of meetings of shareholders shall be sent or otherwise given in
accordance with Section 2.5 of these bylaws not less than ten (10) (or, if sent
by third-class mail pursuant to Section 2.5 of these bylaws, thirty (30)) nor
more than sixty (60) days before the date of the meeting.  The notice shall
specify the place, date, and hour of the meeting and (i) in the case of a
special meeting, the general nature of the business to be transacted (no
business other than that specified in the notice may be transacted) or (ii) in
the case of the annual meeting, those matters which the board of directors, at
the time of giving the notice, intends to present for action by the shareholders
(but, subject to the provisions of the next paragraph of this Section 2.4,
action may be taken on any matter properly brought before the meeting pursuant
to Section 2.15 of these bylaws).  The notice of any meeting at which directors
are to be elected shall include the name of any nominee or nominees who, at the
time of the notice, the board intends to present for election.

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

                                      -2-
<PAGE>
 
     2.5  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE
          --------------------------------------------

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

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

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

     2.6  QUORUM
          ------

     The presence in person or by proxy of the holders of a majority of the
shares entitled to vote thereat constitutes a quorum for the transaction of
business at all meetings of shareholders.  The shareholders present at a duly
called or held meeting at which a quorum is present may continue to do business
until adjournment, notwithstanding the withdrawal of enough shareholders to
leave less than a quorum, if any action taken (other than adjournment) is
approved by at least a majority of the shares required to constitute a quorum.

     2.7  ADJOURNED MEETING; NOTICE
          -------------------------

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

     When any meeting of shareholders, either annual or special, is adjourned to
another time or place, notice need not be given of the adjourned meeting if the
time and place are announced

                                      -3-
<PAGE>
 
at the meeting at which the adjournment is taken.  However, if a new record date
for the adjourned meeting is fixed or if the adjournment is for more than forty-
five (45) days from the date set for the original meeting, then notice of the
adjourned meeting shall be given.  Notice of any such adjourned meeting shall be
given to each shareholder of record entitled to vote at the adjourned meeting in
accordance with the provisions of Sections 2.4 and 2.5 of these bylaws.  At any
adjourned meeting the corporation may transact any business which might have
been transacted at the original meeting.

     2.8  VOTING
          ------

     The shareholders entitled to vote at any meeting of shareholders shall be
determined in accordance with the provisions of Section 2.10 of these bylaws,
subject to the provisions of Sections 702 through 704 of the Code (relating to
voting shares held by a fiduciary, in the name of a corporation or in joint
ownership).

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

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

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

     So long as the Company's Articles of Incorporation so provide, there shall
be no right with respect to shares of stock of the corporation to cumulate votes
in the election of directors.

     2.9  VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT
          -------------------------------------------------

     The transactions of any meeting of shareholders, either annual or special,
however called and noticed, and wherever held, shall be as valid as though they
had been taken at a meeting duly held after regular call and notice, if a quorum
be present either in person or by proxy, and if, either before or after the
meeting, each person entitled to vote, who was not present in person or by
proxy, signs a written waiver of notice or a consent to the holding of the
meeting or an approval of the minutes thereof.  The waiver of notice or consent
or approval need not specify either the business to be transacted or the purpose
of any annual or special meeting of shareholders, except that if action is taken
or proposed to be taken for approval of any of those

                                      -4-
<PAGE>
 
matters specified in the second paragraph of Section 2.4 of these bylaws, the
waiver of notice or consent or approval shall state the general nature of the
proposal.  All such waivers, consents, and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

     Attendance by a person at a meeting shall also constitute a waiver of
notice of and presence at that meeting, except when the person objects at the
beginning of the meeting to the transaction of any business because the meeting
is not lawfully called or convened.  Attendance at a meeting is not a waiver of
any right to object to the consideration of matters required by the Code to be
included in the notice of the meeting but not so included, if that objection is
expressly made at the meeting.

     2.10  RECORD DATE FOR SHAREHOLDER NOTICE; VOTING
           ------------------------------------------

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

     2.11  PROXIES
           -------

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

                                      -5-

     2.12  INSPECTORS OF ELECTION
           ----------------------

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

     Such inspectors shall:

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

          (b) receive votes, ballots or consents:

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

          (d) count and tabulate all votes or consents

          (e) determine when the polls shall close;

          (f)  determine the result; and

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

     2.13  ADVANCE NOTICE OF SHAREHOLDER NOMINEES
           --------------------------------------

     Nominations of persons for election to the board of directors of the
corporation may be made at a meeting of shareholders by or at the direction of
the board of directors or by any shareholder of the corporation entitled to vote
in the election of directors at the meeting who complies with the notice
procedures set forth in this Section.  Such nominations, other than those made
by or at the direction of the board of directors, shall be made pursuant to
timely notice in writing to the Secretary of the corporation.  To be timely, a
shareholder's notice shall be delivered to or mailed and received at the
principal executive offices of the corporation not less than twenty (20) days
nor more than sixty (60) days prior to the meeting; provided, however, that in
                                                    --------  -------         
the event less than thirty (30) days notice or prior public disclosure of the
date of the meeting is given or made to shareholders, notice by the shareholder
to be timely must be so received not later than the close of business on the
tenth day following the day on which such notice of the 

                                      -6-
<PAGE>
 
date of the meeting was mailed or such public disclosure was made. Such
shareholder's notice shall set forth (a) as to each person, if any, whom the
shareholder proposes to nominate for election or re-election as a director: (i)
the name, age, business address and residence address of such person, (ii) the
principal occupation or employment of such person, (iii) the class and number of
shares of the corporation which are beneficially owned by such person, (iv) any
other information relating to such person that is required by law to be
disclosed in solicitations of proxies for election of directors, and (v) such
person's written consent to being named as a nominee and to serving as a
director if elected; and (b) as to the shareholder giving the notice: (i) the
name and address, as they appear on the corporation's books, of such
shareholder, and (ii) the class and number of shares of the corporation which
are beneficially owned by such shareholder, and (iii) a description of all
arrangements or understandings between such shareholder and each nominee and any
other person or persons (naming such person or persons) relating to the
nomination. At the request of the board of directors any person nominated by the

shareholders, notice by the shareholder to be timely must be so received not
later than the close of business on the tenth day following the day on which

disclosure was made.  A shareholder's notice to the secretary shall set forth as
to each matter the shareholder proposes to bring before the annual meeting:  (i)
a brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (ii)

                                   ---------

     3.1  POWERS
          ------

     Subject to the provisions of the Code and any limitations in the articles
of incorporation and these bylaws relating to action required to be approved by
the shareholders or by the outstanding shares, the business and affairs of the
corporation shall be managed and all corporate powers shall be exercised by or
under the direction of the board of directors.

     3.2  NUMBER OF DIRECTORS
          -------------------

     The number of directors of the corporation shall be not less than five (5)
nor more than nine (9).  The exact number of directors shall be seven (7) until
changed, within the limits specified above, by a bylaw amending this Section
3.2, duly adopted by the board of directors or by the shareholders.  The
indefinite number of directors may be changed, or a definite number may be fixed
without provision for an indefinite number, by a duly adopted amendment to the
articles of incorporation or by an amendment to this bylaw duly adopted by the
vote 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 are equal to more than sixteen and
two-thirds percent (16-2/3%) of the outstanding shares entitled to vote thereon.
No amendment may change the stated maximum number of authorized directors to a
number greater than two (2) times the stated minimum number of directors minus
one (1).  No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

     3.3  ELECTION AND TERM OF OFFICE OF DIRECTORS
          ----------------------------------------

     So long as the Company's Articles of Incorporation so provide, directors
shall be elected at each annual meeting of shareholders to hold office as
follows.  At the first annual meeting of shareholders held after September 10,
1994, one-half of the directors shall be elected for a term of two years and
one-half of the directors shall be elected for a term of one year.  If the
number of directors is not divisible by two, the extra director shall be elected
for a term of two years.  At subsequent annual meetings of shareholders, a
number of directors shall be elected equal to the number of directors with terms
expiring at that annual meeting.  Directors elected at each such annual meeting
shall be elected for a term expiring with the annual meeting of shareholders two
years thereafter.

          -------------------------

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

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

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

     The shareholders may elect a director or directors at any time to fill any
vacancy or vacancies not filled by the directors.

present in person at the meeting.

          ------

     A majority of the authorized number of directors shall constitute a quorum
for the transaction of business, except to adjourn as provided in Section 3.10
of these bylaws.  Every act or decision done or made by a majority of the
directors present at a duly held meeting at which a quorum is present shall be

           -------------------------------------------------

     Any action required or permitted to be taken by the board of directors may
be taken without a meeting, provided that all members of the board individually

directors.  Such written consent and any counterparts thereof shall be filed
with the minutes of the proceedings of the board.

capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

           -----------------------------

          -----------------------

     Every director shall have the absolute right at any reasonable time to

     7.5  ANNUAL REPORT TO SHAREHOLDERS; WAIVER
          -------------------------------------

     The board of directors shall cause an annual report to be sent to the
shareholders not later than one hundred twenty (120) days after the close of the
fiscal year adopted by the corporation.  Such report shall be sent at least
fifteen (15) days (or, if sent by third-class mail, thirty-five (35) days)
before the annual meeting of shareholders to be held during the next fiscal year
and in the manner specified in Section 2.5 of these bylaws for giving notice to
shareholders of the corporation.

     The annual report shall contain (i) a balance sheet as of the end of the
fiscal year, (ii) an income statement, (iii) a statement of changes in financial
position for the fiscal year, and (iv) any report of independent accountants or,
if there is no such report, the certificate of an authorized officer of the
corporation that the statements were prepared without audit from the books and
records of the corporation.

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

     7.6  FINANCIAL STATEMENTS
          --------------------

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

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

                                      -18-

     The quarterly income statements and balance sheets referred to in this
section shall be accompanied by the report, if any, of any independent
accountants engaged by the corporation or by the certificate of an authorized
officer of the corporation that the financial statements were prepared without
audit from the books and records of the corporation.

     7.7  REPRESENTATION OF SHARES OF OTHER CORPORATIONS
          ----------------------------------------------

     The chairman of the board, the president, any vice president, the chief
financial officer, the secretary or assistant secretary of this corporation, or
any other person authorized by the board of directors or the president or a vice
president, is 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 may be exercised either by such person directly or by any other person
authorized to do so by proxy or power of attorney duly executed by such person
having the authority.

                                  ARTICLE VIII

                                GENERAL MATTERS

     8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING
          -----------------------------------------------------

     For purposes of determining the shareholders entitled to receive payment of
any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect of any other lawful
action, the board of directors may fix, in advance, a record date, which shall
not be more than sixty (60) days before any such action.  In that case, only
shareholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided in the Code.

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

     8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS
          -----------------------------------------

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

     8.3  CORPORATE CONTRACTS AND INSTRUMENTS;  HOW EXECUTED
          --------------------------------------------------

     The board of directors, except as otherwise provided in these bylaws, may
authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the 

                                      -19-
<PAGE>
 
name of and on behalf of the corporation; such authority may be general or
confined to specific instances. Unless so authorized or ratified by the board of
directors or within the agency power of an officer, no officer, agent or
employee shall have any power or authority to bind the corporation by any
contract or engagement or to pledge its credit or to render it liable for any
purpose or for any amount.

     8.4  CERTIFICATES FOR SHARES
          -----------------------

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

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

     8.5  LOST CERTIFICATES
          -----------------

     Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time.  The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

     8.6  CONSTRUCTION; DEFINITIONS
          -------------------------

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

     9.1  AMENDMENT BY SHAREHOLDERS
          -------------------------

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

     9.2  AMENDMENT BY DIRECTORS
          ----------------------

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