    The annual meeting of the shareholders shall be held on a weekday on such

    Section 4 - Notice of Meeting.

    Written notice stating the place, day and hour of the meeting and the
purpose or purposes for which the meeting is called, shall be delivered not less
than 10 nor more than 60 days before the day of the meeting, either personally
or by mail, by or at the direction of the  President, the Secretary, or the
Officer or persons calling the meeting, to each shareholder of record entitled
to vote at such meeting.  If mailed, such notice shall be deemed to be delivered
when deposited in the United States mail, addressed to the shareholder at his
address as it appears on the stock record books of the Corporation, with postage
thereon prepaid.

    For a meeting to be properly called by the President at the request of the
holders of at least one-tenth of all votes entitled to be cast on any issue
proposed at the meeting, the shareholders requesting the meeting must give
notice of such request in writing containing the applicable information,
required in Sections 12 and 13 hereof, and such notice must be signed and dated
by each such requesting shareholder and delivered to the Secretary at the
principal executive offices of the Corporation.  The Board of Directors shall
promptly, but in all events within 10 business days after the date on which such
notice is received, adopt a resolution (i) setting the date for such meeting,
which date shall be not more than 180 and not less than 10 days from the date on
which such resolution is adopted and (ii) fixing the record date for such
meeting in accordance with Section 5 hereof.  Shareholders requesting such a
meeting shall pay for all costs incurred in connection with calling and holding
such meeting, including all reasonable costs incurred by the Corporation with
respect thereto.

    Any previously scheduled meeting of shareholders may be postponed by
resolution of the Board of Directors upon public notice given prior to the date
previously scheduled for such meeting provided, however, that any special
meeting called at the request of holders of at least one tenth of all votes
entitled to be cast on any issue proposed at the meeting may not be postponed to
a date more than 180 days following the date on which the Board of Directors
adopted the resolution which fixed the original date of such meeting.

    Only such business shall be conducted at a special meeting of shareholders
as shall have been set forth as the purpose or purposes of such special meeting
in the Corporation's notice of such special meeting.

    Section 5 - Fixing of Record Date.

    For the purpose of determining shareholders entitled to notice of or to vote
at any meeting of shareholders or any adjournment thereof, or shareholders
entitled to receive payment of any dividend, or in order to make a determination
of shareholders for any other proper purpose, the Board of Directors of the
Corporation may fix in advance a date as the record date for any such
determination of shareholders, such date in any case to be not more than 70
days, and, in case of a meeting of shareholders, not less than 10 days, prior to
the date on which the particular action, requiring such determination of
shareholders, is to be taken.  If no record date is fixed for the determination
of shareholders entitled to notice of or to vote at a meeting of shareholders or

shareholders entitled to receive payment of a dividend, the date on which notice
of the meeting is mailed or the date on which the resolution of the Board of
Directors declaring such dividend is adopted, as the case may be, shall be the
record date for such determination of shareholders.  When a determination of
shareholders entitled to vote at any meeting of shareholders has been made, as
provided in this section, such determination shall be applied to any adjournment
thereof, provided, however, that the Board of Directors will fix a new record
date if such meeting is adjourned to a date more than 120 days after the date
fixed for the original meeting.

    Section 6 - Voting Lists.

    The officer or agent having charge of the stock transfer books for shares of
the Corporation shall make, within two business days after notice of the meeting
is given, a complete list of the shareholders entitled to vote at such meeting,
or any adjournment thereof, arranged in alphabetical order, with the address of
and the number of shares held by each, which list, until the time of such
meeting, shall be kept on file at the registered office of the Corporation and
shall be subject to inspection by any shareholder at any time during usual
business hours.  Such list shall also be produced and kept open at the time and
place of the meeting and shall be subject to the inspection of any shareholder
during the whole time of the meeting.  The original stock transfer books shall
be prima facie evidence as to who are the shareholders entitled to examine such
list or transfer books or to vote at any meeting of shareholders.  Failure to
comply with the requirements of this section shall not affect the validity of
any action taken at such meeting.

    Section 7 - Quorum.

    A majority of the outstanding shares of the Corporation entitled to vote,
represented in person or by proxy, shall constitute a quorum at a meeting of
shareholders.  Whether or not such quorum is present or represented at any
meeting of shareholders, the Chairman of the meeting may adjourn the meeting
from time to time without further notice other than announcement at the meeting;
provided, however, that when a meeting is so adjourned to another time or place,
notice of the adjourned meeting need not be given only if the date, time and
place thereof are announced at the original meeting, if the adjournment is for
not more than 120 days and if no new record date is fixed for the adjourned
meeting.  At such adjourned meeting at which a quorum shall be present or
represented, only such business may be transacted which might have been
transacted at the meeting as originally notified.  The Chairman of the Board of
Directors shall act as the Chairman of all meetings of shareholders and, in the
absence of the Chairman of the Board of Directors, the President shall preside.
In the absence of the President, the Board of Directors shall designate any
other Director, Officer or employee of the Corporation to preside at such
meeting.

    Section 8 - Proxies.

    At all meetings of shareholders, a shareholder entitled to vote may vote by
proxy appointed in writing by the shareholder or by his duly authorized attorney
in fact.  Such proxy shall be filed with the Secretary of the Corporation before
or at the time of the meeting.  No proxy shall be valid after eleven months from
the date of its execution, unless otherwise provided in the proxy.

    Section 9 - Voting of Shares.

    Subject to the Articles of Incorporation, each outstanding share entitled to
vote shall be entitled to one vote upon each matter submitted to a vote at a
meeting of shareholders.  Unless otherwise required by the Articles of
Incorporation or applicable law, Directors shall be elected by a plurality of
the votes cast by the shares entitled to vote in the election at which a quorum
is present.  Unless otherwise required by the Articles of Incorporation or
applicable law, the affirmative vote of the holders of a majority of the shares
present or represented at a meeting of shareholders at which a quorum is present
or represented shall be required to decide all matters brought before such
meeting other than the election of Directors.

    Section 10 - Voting Company's Shares.

    Shares of the Corporation belonging to it shall not be voted directly or
indirectly at any meeting and shall not be counted in determining the total
number of outstanding shares at any given time, but shares held by this
Corporation in a fiduciary capacity may be voted and shall be counted in
determining the total number of outstanding shares at any given time.

    Section 11 - Shares in Other Corporation's Name.

    Shares standing in the name of another corporation may be voted either in
person or by proxy,  by a duly appointed officer of such corporation who has
been authorized to cast such votes or execute such proxies.  A proxy executed by
any principal officer of such other corporation shall be conclusive evidence of
the signer's authority to act, in the absence of express notice to this
Corporation, given in writing to the Secretary of this Corporation, of the
designation of some other person by the board of directors or the by-laws of
such corporation.

    Section 12 - Notice of Shareholder Business.

    At all meetings of the shareholders, only such business shall be conducted
as shall have been brought before the meeting (a) by or at the direction of the
Board of Directors or (b) by any shareholder of the Corporation who was a
shareholder of record at the time of the giving of notice as provided in this
Section 12, who is entitled to vote at the meeting and who complies with the
notice procedures set forth in this Section 12.  In order for business to be
properly brought before the meeting by a shareholder, such business, as
determined by the Chairman of the meeting, must be a proper subject under
Wisconsin law.  For business to be properly brought before an annual meeting by
a shareholder, the shareholder must have given timely notice thereof in writing
to the Secretary of the Corporation.  To be timely, a shareholder's notice must
be delivered to or mailed and received at the principal executive offices of the
Corporation, not less than 60 days nor more than 90 days prior to the meeting;
provided, however, that in the event that less than 70 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 received not later than the close
of business on the tenth day following the day on which such notice of the date
of the meeting was mailed or such public disclosure was made.  A shareholder's
notice to the Secretary shall set forth

as to each matter the shareholder proposes to bring before the meeting (a) a
brief description of the business desired to be brought before the meeting and
the reasons for conducting such business at the meeting, (b) the name and

business.

    Section 13 - Notice of Shareholder Nominees.

    Only persons who are nominated in accordance with the procedures set forth

of the Corporation who was a shareholder of record at the time of the giving of
notice provided for in this Section 13, who is entitled to vote for the election
of directors at the meeting and who complies with the notice procedures set
forth in this Section 13.  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 the principal executive offices of the Corporation
not less than 60 days nor more than 90 days prior to the meeting; provided,
however, that in the event that less than 70 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 date of
the meeting was mailed or such public disclosure was made.  Such shareholder's
notice shall set forth (a) as to each person whom the shareholder proposes to
nominate for election or re-election as a director (i) the name, age, business
address, and residence of such nominee; (ii) the principal occupation or
employment of such nominee; (iii) the class and number of shares of the
Corporation which are beneficially owned by such nominee; and (iv) any other
information relating to such person that is required to be disclosed in
solicitations of proxies for election of directors pursuant to Regulation 14A
under the Securities Exchange Act of 1934, as amended (including such person's
written consent to being named in the proxy statement 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.  No person shall be eligible
for election as a director of the Corporation unless nominated in accordance
with the procedures set forth in the By-Laws.

    Section 14 - Acceptance of Nominations and Proposals.

    The Secretary shall have the power and duty to determine whether a
nomination or any business proposed to be brought before the meeting was made in
accordance with the procedures set forth in Sections 12 and 13.  The Secretary
shall make any such determination and shall notify the interested shareholder of
such determination (including the reasons for any determination that the
interested shareholder's nomination or proposal was not made in compliance with
these Sections 12 and 13) within 15 days after the Corporation's receipt of the
shareholder's notice required by Sections 12 and 13.  If the Secretary

such shareholder of any such notice declaring that such shareholder's nomination
or proposal was not made in compliance with Sections 12 and 13 to rectify any
deficiency cited in such notice and to resubmit such shareholder's nomination or
proposal to the Secretary at the principal business office of the Corporation.
Any resubmitted nomination or proposal shall contain only such nominations or
proposals as were submitted to the Corporation in such shareholder's notice
which did not comply with Sections 12 and 13. The Secretary shall determine
whether any such resubmitted nomination or proposal is in compliance with
Sections 12 and 13, and shall notify the interested shareholder of such
determination (including the reasons for any determination that the interested
shareholder's resubmitted nomination or proposal was not made in compliance with
Sections 12 and 13), within five additional days of the Corporation's receipt of
such shareholder's resubmitted nomination or proposal.

    Section 15 - Compliance with Exchange Act.

    Notwithstanding the provisions of Sections 12 and 13, a shareholder shall
also comply with all applicable requirements of the Exchange Act and the rules
and regulations thereunder with respect to the matters set forth in Sections 12
and 13.  Nothing in this Section 15 shall be deemed to affect any rights of
shareholders to request inclusion of proposals in the Corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

    Section 16 - Definitions.

    For purposes of this Article II, "public announcement" or "public

    Section 2 - Number, Tenure and Qualifications.

    The number of directors who shall constitute the whole Board of Directors
shall be the number fixed from time to time by the Board of Directors in
accordance with the Articles of Incorporation and shall in no event be less than
7 nor more than 11.

    The directors shall be divided into three classes as nearly equal in number
as possible.  At the 1986 annual meeting of shareholders the directors were so
divided, with the term of office of the first class to expire at the 1987 annual
meeting of shareholders, the term of office of the second class to expire at the
1988 annual meeting of shareholders and the third class to expire at the 1989
annual meeting of shareholders.  At each annual meeting of shareholders,
directors elected to succeed those whose terms expire shall be elected for a
term of office expiring at the third succeeding annual meeting of shareholders
after their election and until their successors shall be elected and shall
qualify.  Directors need not be residents of the State of Wisconsin or
shareholders of the Corporation.

    An individual that is 70 years of age or older shall not be eligible for

individual who is an incumbent Director   shall be eligible for nomination as a
Director of the Corporation for one additional term after he/she has attained

Directors may provide by resolution, the time and place, either within or
without the State of Wisconsin, for the holding of additional regular meetings
without other notice than such resolution.

    Section 4 - Special Meetings.

    Special meetings of the Board of Directors may be called by or at the
request of the Chairman of the Board, Secretary or any two directors.  The
person or persons authorized to call special meetings of the Board of Directors
may fix any place, either within or without the State of Wisconsin, as the place
for holding any special meeting of the Board of Directors called by them.

    Section 5 - Notice.

    Notice of any special meeting shall be given at least 48 hours previously
thereto by written notice delivered personally or mailed to each director at his
business address, or by telegram.  If mailed, such notice shall be deemed to be
delivered when deposited in the United States mail so addressed, with postage
thereon prepaid.  If Notice be given by telegram, such notice shall be deemed to
be delivered when the telegram is delivered to the telegraph company.  Whenever
any notice whatever is required to be given to any director of the Corporation

these by-laws or under the provisions of the articles of incorporation or under
the provisions of any statute, a waiver thereof in writing, signed at any time,
whether before or after the time of meeting, by the director entitled to such
notice, shall be deemed equivalent to the giving of such notice. The attendance
of a director at a meeting shall constitute a waiver of notice of such meeting,
except where a director attends a meeting and objects thereat to the transaction
of any business because the meeting is not lawfully called or convened. Neither
the business to be transacted at, nor the purpose of, any regular or special
meeting of the Board of Directors need be specified in the notice or waiver of
notice of such meeting.

    Section 6 - Quorum.

    A majority of the number of directors fixed by Section 2 of this Article III
shall constitute a quorum for the transaction of business at any meeting of the
Board of Directors, but though less than such quorum is present at a meeting, a
majority of the directors present may adjourn the meeting from time to time
without further notice.

    Section 7 - Resignations.

    Any Director, member of a committee or other Officer may resign at any time.
Such resignation shall be made in writing and shall take effect at the time
specified therein and if no time is specified, at the time of its receipt by the
Chairman of the Board or Secretary.  The acceptance of a resignation shall not
be necessary to make it effective.

    Section 8 - Newly-Created Directorships and Vacancies.

    Newly-created directorships resulting from any increase in the authorized
number of directors or any vacancies in the Board of Directors resulting from
death, resignation, retirement, disqualification, removal from office or other
cause shall be filled by a majority vote of the directors then in office, though
less than a quorum.  Directors so chosen shall hold office for a term expiring
at the annual meeting of shareholders at which the term of the class to which
they have been elected expires and until their successors shall be elected and
shall qualify.  No decrease in the number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

    Section 9 - Removal.

    Any director, or the entire Board of Directors, may be removed from office
at any time, but only for cause and only by the affirmative vote of the holders
of 66-2/3% of the voting power of all the shares of the Corporation entitled to
vote for the election of directors.

    Section 10 - Compensation.

    The Board of Directors, by affirmative vote of a majority of the Directors

Officers or otherwise, or may delegate such authority to an appropriate
committee.

    Section 11 - Presumption of Assent.

    A Director of the Corporation who is present at a meeting of the Board of
Directors or a committee thereof at which action on any corporate matter is
taken shall be presumed to have assented to the action taken unless his dissent
shall be entered in the minutes of the meeting or unless he shall file his
written dissent to such action with the person acting as the secretary of the
meeting before the adjournment thereof or shall forward such dissent by
registered mail to the Secretary of the Corporation immediately after the
adjournment of the meeting.  Such right to dissent shall not apply to a director
who voted in favor of such action.

    Section 12 - Committees.

    The Board of Directors by resolution adopted by the affirmative vote of a
majority of the number of directors fixed by Section 2 of this Article III may
designate one or more committees, each committee to consist of three or more
directors elected by the Board of Directors, which to the extent provided in
said resolution, as initially adopted, and as thereafter supplemented or amended
by further resolution adopted by a like vote, shall have and may exercise, when
the Board of Directors is not in session, the powers of the Board of Directors
in the management of the business and affairs of the Corporation, except action
in respect to dividends to shareholders, election of Officers or the filling of
vacancies in the Board of Directors or committee created pursuant to this
section.  The Board of Directors may elect one or more of its members as
alternate members of any such committee who may take the place of any absent
member or members at any meeting of such committee, upon request by the Chairman
of the Board or upon request by the President or upon request by the chairman of
such meeting.  Each such committee shall fix its own rules governing the conduct
of its activities and shall make such reports to the Board of Directors of its
activities as the Board of Directors may request.

    Section 13 - Informal Action by Directors.

    Any action required to be taken at a meeting of the Board of Directors or
any committee thereof, or any other action which may be taken at a meeting of
the Board of Directors or any committee thereof, may be taken without a meeting
if a consent in writing setting forth the action so taken shall be signed by all
of the directors or members of such committee, as the case may be, entitled to
vote with respect to the subject matter thereof.

    The principal Officers of the Corporation shall be a Chairman of the Board,
a President, a Chief Executive Officer, one or more Vice Presidents, a
Controller, a Secretary and a Treasurer, each of whom shall be elected by the
Board of Directors.  Such other Officers and assistant Officers as may be deemed

Directors may choose not to fill any office for any period as it may deem
advisable.

    Section 2 - Election and Term of Office.

    The Officers of the Corporation to be elected by the Board of Directors
shall be elected annually by the Board of Directors at the last meeting of the
Board of Directors held prior to the Annual Meeting of the Shareholders or at
the first meeting of the Board of Directors held after  the Annual Meeting of
the Shareholders.  If the election of Officers shall not be held at either of
such meetings, such election shall be held as soon thereafter as conveniently

removed by the Board of Directors whenever in its judgment the best interests of
the Corporation will be served thereby, but such removal shall be without
prejudice to the contract rights, if any, of the person so removed.  Election or
appointment shall not of itself create contract rights.  The Chief Executive
Officer may suspend at any time any Officer other than the Chairman of the
Board.  The Board of Directors will determine at the next regular Board meeting
following a suspension, whether the suspension should result in the removal of
the Officer.

    Section 4 - Vacancies.

    A vacancy in any principal office because of death, resignation, removal,
disqualification or otherwise, shall be filled by the Board of Directors for the
unexpired portion of the term.

     Each person who was or is made a Party or is threatened to be made a Party
to or is involved in or called as a witness in any Proceeding by reason of the
fact that he or she, or a person of who he or she is the legal representative,
is, was or had agreed to become a Director or Officer of the Corporation or a
director or officer of an Affiliate (who is not otherwise serving as a Director
or Officer) shall be indemnified and held harmless by the Corporation to the
fullest extent permitted under the Statute, as the same now exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits the Corporation to provide broader indemnification
rights than the Statute permitted the Corporation to provide prior to such
amendment) against all Expenses and Liabilities incurred or suffered by such
person in connection therewith; provided, that except with respect to a
Proceeding brought before an Authority or otherwise to enforce rights hereunder,

affirming his or her good faith belief that he or she has not engaged in a
Breach of Duty, and (ii) an unsecured written undertaking ("Undertaking"),
executed personally or on his or her behalf, to repay any allowances made under
this Section 3 if it is ultimately determined by an Authority that such person
is not entitled to be indemnified by the Corporation for such Expenses;
provided, further, that in connection with a Proceeding (or part thereof)
initiated by any such person, except with respect to a Proceeding brought before
an Authority or otherwise to enforce rights hereunder, the Corporation shall pay
such Expenses as incurred only if such Proceeding (or part thereof) was
authorized by the Board.  The Undertaking shall also provide that the person to
whom an allowance was paid pursuant to this Section 3 shall not be obligated to
repay the Corporation during the pendency of any Proceeding before an Authority,
and that if the Authority shall ultimately determine that such person is not
entitled to indemnification for such Expenses, such person shall not be required
to pay interest on such allowance.  The Board shall not require, and shall
accept the Undertaking without any showing of the claimant's ability to repay
the allowance.

     Section 4 - Procedural Requirements.

(a) Each person who seeks indemnification under Section 2 of this Article shall
    make a written request therefore to the Corporation. The Board shall act on
    such request at its next meeting held no less than two days, but no more
    than sixty days, after the receipt of such request. Such action shall be
    taken by a Disinterested Quorum or, if a Disinterested Quorum cannot be
    obtained, by a Disinterested Committee, which shall determine whether the
    claimant's conduct constituted a Breach of Duty. If such determination is
    favorable to the claimant, the Corporation shall pay or reimburse such
    claimant for the entire amount of requested Liabilities incurred by such
    claimant in connection with the subject Proceeding (net of any Expenses
    previously advanced pursuant to Section 3). If such determination is not
    favorable to the claimant or if a Disinterested Committee cannot be
    obtained, the Board by resolution shall authorize an Authority, as provided
    in Section 5 of this Article, to determine whether the claimant's conduct
    constituted a Breach of Duty and, therefore, whether indemnification is
    required hereunder. The determination by an Authority that indemnification
    is required hereunder shall be binding upon the Corporation regardless of
    any prior determination that the claimant engaged in a Breach of Duty.

(b) If the Board does not authorize an Authority to determine the claimant's
    right to indemnification hereunder, and indemnification of the requested
    amount of Liabilities is paid by the Corporation, it shall be conclusively
    presumed that a Disinterested Quorum has determined that the claimant did
    not engage in misconduct constituting a Breach of Duty.

     Section 5 - Determination of Indemnification.

(a) If the Board authorizes an Authority to determine a claimant's right to
    indemnification pursuant to Section 4 of this Article, then the claimant
    shall have the absolute discretionary authority to select one of the
    following as such Authority:

      (i) An independent legal counsel; provided, that such counsel shall be
          mutually selected by such claimant and by a majority vote of a
          Disinterested Quorum or, if a Disinterested Quorum cannot be obtained,
          then by a majority vote of a Disinterested Committee or, if a
          Disinterested Committee cannot be obtained, then by a majority vote of
          the Board;

     (ii) A panel of three arbitrators selected from the panels of arbitrators
          of the American Arbitration Association in Chicago, Illinois;
          provided, that (A) one arbitrator shall be selected by such claimant,
          the second arbitrator shall be selected by a majority vote of a
          Disinterested Quorum or, if a Disinterested Quorum cannot be obtained,
          then by a majority vote of a Disinterested Committee or, if a
          Disinterested Committee cannot be obtained, then by a majority vote of
          the Board, and the third arbitrator shall be selected by the two
          previously selected arbitrators; and (B) in all other respects such
          panel shall be governed by the American Arbitration Association's then
          existing Commercial Arbitration Rules; or

     (iii) A court pursuant to and in accordance with Section 180.051 of the
           Statute.

(b)  In any such determination by the selected Authority there shall exist a
     rebuttable presumption that the claimant's conduct did not constitute a
     Breach of Duty and that indemnification against the requested amount of
     Liabilities is required. The burden of rebutting such a presumption by
     clear and convincing evidence shall be on the Corporation or such other
     party asserting that such indemnification should not be allowed.

(c)  The Authority shall make its determination as soon as practicable (but in
     any event within sixty days of being selected) and shall submit a written
     opinion of its conclusion simultaneously to both the Corporation and the
     claimant.

(d)  If the Authority determines that indemnification is required hereunder, the
     Corporation shall pay the entire requested amount of Liabilities (net of
     any Expenses previously advanced pursuant to Section 3), including interest
     thereon at a reasonable rate, as determined by the Authority, within ten
     days of receipt of the Authority's opinion; provided, that, if it is
     determined by the Authority that a claimant is entitled to indemnification
     as to some claims, issues or matters, but not as to other claims, issues or
     matters involved in the subject Proceeding, the Corporation shall be
     required to pay (as set forth above) only the amount of such requested
     Liabilities as the Authority shall deem appropriate in light of all of the
     circumstances of such Proceeding.

(e)  All expenses incurred in the determination process under this Section 5 by
     either the Corporation or the claimant, including, without limitation, all
     Expenses of the selected Authority, shall be paid by the Corporation.

     Section 6 - Employees and Agents.

     The Board may, in its sole and absolute discretion as it deems appropriate,
pursuant to a majority vote thereof, indemnify against Liabilities incurred by,
and/or provide for the allowance of reasonable Expenses of, an employee or agent
of the Corporation who is not otherwise a Director or Officer.

     Section 7 - Insurance.

     The Corporation may purchase and maintain, at its expense, insurance on
behalf of a Director or Officer or any individual who is or was an employee or
agent of the Corporation against any Liability asserted against or incurred by
such individual in his or her capacity as such or arising from his or her status
as such, regardless of whether the Corporation is required or permitted to
indemnify or allow Expenses to such individual against any such Liability under
the Statute or this Article.

     Section 8 - Non-Exclusivity of Rights.

     The rights conferred on any person by this Article shall not be deemed
exclusive of any other rights to indemnification or advancement of Expenses
which such person may be entitled to under any written agreement, Board
resolution, vote of shareholders of the Corporation or otherwise, including,
without limitation, under the Statute.  Nothing contained in this Article shall
be deemed to limit the Corporation's obligations to indemnify any person under
the Statute.

     Section 9 - Contractual Nature.

     The provisions of this Article shall be applicable to all Proceedings
commenced after its adoption, whether such arise out of events, acts or
omissions which occurred prior or subsequent to such adoption, and shall
continue as to a person who has ceased to be a Director or Officer and shall
inure to the benefit of the heirs, executors and administrators of such person.
This Article shall be deemed to be a contract between the Corporation and each
person who, at any time that this Article is in effect, serves or agrees to
serve in any capacity which entitles him to indemnification hereunder and any
repeal or other modification of this Article or any repeal or modification of
the Statute or any other applicable law shall not limit any rights of
indemnification then existing or arising out of events, acts or omissions
occurring prior to such repeal or modification, including, without limitation,
the right to indemnification for Proceedings commenced after such repeal or
modification to enforce this Article with regard to acts, omissions or events
arising prior to such repeal or modification.

     Section 10 - Severability.

     If any provision of this Article shall be deemed invalid or inoperative, or
if a court of competent jurisdiction determines that any of the provisions of
this Article contravene public policy, this Article shall be construed so that
the remaining provisions shall not be affected, but shall remain in full force
and effect, and any such provisions which are invalid or inoperative or which
contravene public policy shall be deemed, without further action or deed by or
on behalf of the Corporation, to be modified, amended and/or limited, but only
to the extent necessary to render the same valid and enforceable.

     Section 11 - Continuation of Obligations; Amendment.

     The obligations of the Corporation to indemnify any person or to advance
Expenses thereto under this Article shall continue as to the successors and
assigns of the Corporation and such obligations may only be limited by the
affirmative vote of two-thirds of the shareholders of the Corporation so
entitled to vote; provided, that any such limitation shall only apply to alleged
acts of any person for which indemnification is sought hereunder which occur
after such limitation is adopted.
