                                PREFERRED STOCK

         The rights, preferences and privileges and qualifications,
limitations and restrictions granted to and imposed on the shares of Preferred
Stock of the corporation shall be as set forth below in this Division A.

         Shares of Preferred Stock may be issued in one or more series at such
time or times, and for such consideration or considerations, as the board of
directors shall determine. The board of directors is hereby authorized to fix,
state and establish, in the resolution or resolutions providing for the
issuance of any wholly unissued series of Preferred Stock, the relative
powers, rights, designations, preferences, qualifications, limitations and
restrictions of such series in relation to any other series of Preferred Stock
at the time outstanding. The board of directors is also expressly authorized
to fix the number of shares of each such series, but not below the number of
shares thereof then outstanding. The authority of the board of directors with
respect to each series of Preferred Stock shall include (without limitation)
the determination of the following:

                  (a) the dividend rate on the shares of such series,
whether dividends shall be cumulative, and, if so, from which date or
dates, and the rights of priority, if any, with respect to the payment of
dividends on the shares of such series relative to other series of
Preferred Stock or classes of stock;

                  (b) whether the shares of such series shall have voting
rights (other than the voting rights provided by law) and, if so, the terms
and extent of such voting rights;

                  (c) whether the shares of such series shall have
conversion privileges, and, if so, the terms and conditions of such
conversion, including provision for adjustment of the conversion rate upon
the occurrence of such events as the board of directors may prescribe;

                  (d) whether the shares of such series shall be subject to
redemption by the corporation or at the request of the holder(s) thereof,
and, if so, the terms and conditions of any such redemption;

                  (e) the rights of the shares of such series in the event
of voluntary or involuntary liquidation, dissolution or winding up of the
corporation, and the rights of priority, if any, with respect to the
distribution of assets on the shares of such series relative to other
series of Preferred Stock or classes of stock; and

                  (f) any other preferences, privileges and powers, and
relative, participating, optional or other special rights, and
qualifications, limitations or restrictions of such series, as the board of
directors may deem advisable and as shall not be inconsistent with the
provisions of this Certificate of Incorporation, as the same may be amended
from time to time.

                                  * * * *

                  Pursuant to the above stated authority, the board of
directors has designated the following series of Preferred Stock:

                  SECTION 1. DESIGNATION AND AMOUNT.

                  The shares of such series shall be designated as "Series A
Junior Participating Preferred Stock" and the number of shares constituting
such series shall be 140,000.

                  SECTION 2. DIVIDENDS AND DISTRIBUTIONS.

                  (a) The holders of shares of Series A Junior Participating
Preferred Stock shall be entitled to receive, when, as and if declared by the
board of directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the last day of March, June, September and
December in each year (each such date being referred to herein as a "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment
Date after the first issuance of a share or fraction of a share of Series A
Junior Participating Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to the greater of (x) $.01 or (y) subject to the provision
for adjustment hereinafter set forth, 1,000 times the aggregate per share
amount of all cash dividends, and 1,000 times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions other than
a dividend payable in shares of Class A Common Stock or a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise),
declared on the Class A Common Stock, since the immediately preceding
Quarterly Dividend Payment Date, or, with respect to the first Quarterly
Dividend Payment Date, since the first issuance of any share or fraction of a
share of Series A Junior Participating Preferred Stock. In the event the
corporation shall at any time after the date of consummation of the merger of
CME Merger Subsidiary Inc. with and into the Exchange (as defined below) (the
"Rights Declaration Date") (i) declare any dividend on Class A Common Stock
payable in shares of Class A Common Stock, (ii) subdivide the outstanding
Class A Common Stock, or (iii) combine the outstanding Class A Common Stock
into a smaller number of shares, then in each such case the amount to which
holders of shares of Series A Junior Participating Preferred Stock were
entitled immediately prior to such event under clause (y) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Class A Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Class A Common Stock that were outstanding immediately prior to such
event.

                  (b) The corporation shall declare a dividend or distribution
on the Series A Junior Participating Preferred Stock as provided in Paragraph
(a) above immediately after it declares a dividend or distribution on the
Class A Common Stock (other than a dividend payable in shares of Class A
Common Stock); provided that, in the event no dividend or distribution shall
have been declared on the Class A Common Stock during the period between any
Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend
Payment Date, a dividend of $.01 per share on the Series A Junior
Participating Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

                  (c) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such
shares of Series A Junior Participating Preferred Stock, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Junior Participating Preferred
Stock entitled to receive a quarterly dividend and before such Quarterly
Dividend Payment Date, in either of which events such dividends shall begin to
accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued
but unpaid dividends shall not bear interest. Dividends paid on the shares of
Series A Junior Participating Preferred Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall
be allocated pro rata on a share-by-share basis among all such shares at the
time outstanding. The board of directors may fix a record date for the
determination of holders of shares of Series A Junior Participating Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 30 days prior to the date
fixed for the payment thereof.

                  SECTION 3. VOTING RIGHTS.

                  The holders of shares of Series A Junior Participating
Preferred Stock shall have the following voting rights:

                  (a) Subject to the provision for adjustment hereinafter set
forth, each share of Series A Junior Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters submitted to a vote
of the shareholders of the corporation. In the event the corporation shall at
any time after the Rights Declaration Date (i) declare any dividend on Class A
Common Stock payable in shares of Class A Common Stock, (ii) subdivide the
outstanding Class A Common Stock, or (iii) combine the outstanding Class A
Common Stock into a smaller number of shares, then in each such case the
number of votes per share to which holders of shares of Series A Junior
Participating Preferred Stock were entitled immediately prior to such event
shall be adjusted by multiplying such number by a fraction the numerator of
which is the number of shares of Class A Common Stock outstanding immediately
after such event and the denominator of which is the number of shares of Class
A Common Stock that were outstanding immediately prior to such event.

                  (b) Except as otherwise provided herein or by law, the
holders of shares of Series A Junior Participating Preferred Stock and the
holders of shares of Class A Common Stock and Class B Common Stock shall vote
together as one class on all matters submitted to a vote of shareholders of
the corporation.

                  (c)         (i) If at any time dividends on any Series A
         Junior Participating Preferred Stock shall be in arrears in an amount
         equal to six quarterly dividends thereon, the occurrence of such
         contingency shall mark the beginning of a period (herein called a
         "default period") which shall extend until such time when all accrued
         and unpaid dividends for all previous quarterly dividend periods and
         for the current quarterly dividend period on all shares of Series A
         Junior Participating Preferred Stock then outstanding shall have been
         declared and paid or set apart for payment. During each default
         period, all holders of Preferred Stock (including holders of the
         Series A Junior Participating Preferred Stock) with dividends in
         arrears in an amount equal to six quarterly dividends thereon, voting
         as a class, irrespective of series, shall have the right to elect two
         directors.

                              (ii) During any default period, such voting
         right of the holders of Series A Junior Participating Preferred Stock
         may be exercised initially at a special meeting called pursuant to
         Paragraph (c)(iii) of this Section 3 or at any annual meeting of
         shareholders, and thereafter at annual meetings of shareholders,
         provided that such voting right shall not be exercised unless the
         holders of 10% in number of shares of Preferred Stock outstanding
         shall be present in person or by proxy. The absence of a quorum of
         the holders of Common Stock shall not affect the exercise by the
         holders of Preferred Stock of such voting right. At any meeting at
         which the holders of Preferred Stock shall exercise such voting right
         initially during an existing default period, they shall have the
         right, voting as a class, to elect directors to fill such vacancies,
         if any, in the board of directors as may then exist up to two
         directors or, if such right is exercised at an annual meeting, to
         elect two directors. If the number which may be so elected at any
         special meeting does not amount to the required number, the holders
         of the Preferred Stock shall have the right to make such increase in
         the number of directors as shall be necessary to permit the election
         by them of the required number. After the holders of the Preferred
         Stock shall have exercised their right to elect directors in any
         default period and during the continuance of such period, the number
         of directors shall not be increased or decreased except by vote of
         the holders of Preferred Stock as herein provided or pursuant to the
         rights of any equity securities ranking senior to or pari passu with
         the Series A Junior Participating Preferred Stock.

                              (iii) Unless the holders of Preferred Stock
         shall, during an existing default period, have previously exercised
         their right to elect directors, the board of directors may order, or
         any shareholder or shareholders owning in the aggregate not less than
         10% of the total number of shares of Preferred Stock outstanding,
         irrespective of series, may request, the calling of a special meeting
         of the holders of Preferred Stock, which meeting shall thereupon be
         called by the Chairman of the Board, the President, any Managing
         Director or the Secretary of the corporation. Notice of such meeting
         and of any annual meeting at which holders of Preferred Stock are
         entitled to vote pursuant to this Paragraph (c)(iii) shall be given
         to each holder of record of Preferred Stock by mailing a copy of such
         notice to him or her at his or her last address as the same appears
         on the books of the corporation. Such meeting shall be called for a
         time not earlier than 20 days and not later than 60 days after such
         order or request or in default of the calling of such meeting within
         60 days after such order or request, such meeting may be called on
         similar notice by any shareholder or shareholders owning in the
         aggregate not less than 10% of the total number of shares of
         Preferred Stock outstanding. Notwithstanding the provisions of this
         Paragraph (c)(iii), no such special meeting shall be called during
         the period within 60 days immediately preceding the date fixed for
         the next annual meeting of the shareholders.

                              (iv) In any default period, the holders of
         Common Stock, and other classes of stock of the corporation if
         applicable, shall continue to be entitled to elect the whole number
         of directors until the holders of Preferred Stock shall have
         exercised their right to elect two directors voting as a class, after
         the exercise of which right (x) the directors so elected by the
         holders of Preferred Stock shall continue in office until their
         successors shall have been elected by such holders or until the
         expiration of the default period, and (y) any vacancy in the board of
         directors may (except as provided in Paragraph (c)(ii) of this
         Section 3) be filled by vote of a majority of the remaining directors
         theretofore elected by the holders of the class of stock which
         elected the director whose office shall have become vacant.
         References in this Paragraph (c) to directors elected by the holders
         of a particular class of stock shall include directors elected by
         such directors to fill vacancies as provided in clause (y) of the
         foregoing sentence.

                              (v) Immediately upon the expiration of a default
         period, (x) the right of the holders of Preferred Stock as a class to
         elect directors shall cease, (y) the term of any directors elected by
         the holders of Preferred Stock as a class shall terminate, and (z)
         the number of directors shall be such number as may be provided for
         in the certificate of incorporation or bylaws irrespective of any
         increase made pursuant to the provisions of Paragraph (c)(ii) of this
         Section 3 (such number being subject, however, to change thereafter
         in any manner provided by law or in the certificate of incorporation
         or bylaws). Any vacancies in the board of directors effected by the
         provisions of clauses (y) and (z) in the preceding sentence may be
         filled by a majority of the remaining directors.

                  (d) Except as set forth herein, holders of Series A Junior
Participating Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to vote
with holders of Common Stock as set forth herein) for taking any corporate
action.

                  SECTION 4. CERTAIN RESTRICTIONS.

                  (a) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of
Series A Junior Participating Preferred Stock outstanding shall have been paid
in full, the corporation shall not:

                              (i) declare or pay dividends on, make any other
         distributions on, or redeem or purchase or otherwise acquire for
         consideration any shares of stock ranking junior (either as to
         dividends or upon liquidation, dissolution or winding up) to the
         Series A Junior Participating Preferred Stock;

                              (ii) declare or pay dividends on or make any
         other distributions on any shares of stock ranking on a parity
         (either as to dividends or upon liquidation, dissolution or winding
         up) with the Series A Junior Participating Preferred Stock, except
         dividends paid ratably on the Series A Junior Participating Preferred
         Stock and all such parity stock on which dividends are payable or in
         arrears in proportion to the total amounts to which the holders of
         all such shares are then entitled;

                              (iii) redeem or purchase or otherwise acquire
         for consideration shares of any stock ranking on a parity (either as
         to dividends or upon liquidation, dissolution or winding up) with the
         Series A Junior Participating Preferred Stock, provided that the
         corporation may at any time redeem, purchase or otherwise acquire
         shares of any such parity stock in exchange for shares of any stock
         of the corporation ranking junior (either as to dividends or upon
         dissolution, liquidation or winding up) to the Series A Junior
         Participating Preferred Stock; or

                              (iv) purchase or otherwise acquire for
         consideration any shares of Series A Junior Participating Preferred
         Stock, or any shares of stock ranking on a parity with the Series A
         Junior Participating Preferred Stock, except in accordance with a
         purchase offer made in writing or by publication (as determined by
         the board of directors) to all holders of such shares upon such terms
         as the board of directors, after consideration of the respective
         annual dividend rates and other relative rights and preferences of
         the respective series and classes, shall determine in good faith will
         result in fair and equitable treatment among the respective series or
         classes.

                  (b) The corporation shall not permit any subsidiary of the
corporation to purchase or otherwise acquire for consideration any shares of
stock of the corporation unless the corporation could, under Paragraph (a) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

                  SECTION 5. REACQUIRED SHARES.

                  Any shares of Series A Junior Participating Preferred Stock
purchased or otherwise acquired by the corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All
such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the board of
directors, subject to the conditions and restrictions on issuance set forth
herein.

                  SECTION 6. LIQUIDATION, DISSOLUTION OR WINDING UP.

                  (a) Upon any liquidation (voluntary or otherwise),
dissolution or winding up of the corporation, no distribution shall be made to
the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Junior Participating
Preferred Stock unless, prior thereto, the holders of shares of Series A
Junior Participating Preferred Stock shall have received an amount equal to
1,000 times the Exercise Price, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series A Liquidation Preference"). Following the payment of
the full amount of the Series A Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series A Junior
Participating Preferred Stock unless, prior thereto, the holders of shares of
Common Stock shall have received an amount per share (the "Common Adjustment")
equal to the quotient obtained by dividing (i) the Series A Liquidation
Preference by (ii) 1,000 (as appropriately adjusted as set forth in Paragraph
(c) of this Section 6 to reflect such events as stock splits, stock dividends
and recapitalizations with respect to the Common Stock) (such number in clause
(ii), the "Adjustment Number"). Following the payment of the full amount of
the Series A Liquidation Preference and the Common Adjustment in respect of
all outstanding shares of Series A Junior Participating Preferred Stock and
Common Stock, respectively, holders of Series A Junior Participating Preferred
Stock and holders of shares of both classes of Common Stock shall receive
their ratable and proportionate share of the remaining assets to be
distributed in the ratio of the Adjustment Number to 1 with respect to such
Preferred Stock and Common Stock, on a per share basis, respectively.

                  (b) In the event, however, that there are not sufficient
assets available to permit payment in full of the Series A Liquidation
Preference and the liquidation preferences of all other series of preferred
stock, if any, which rank on a parity with the Series A Junior Participating
Preferred Stock, then such remaining assets shall be distributed ratably to
the holders of such parity shares in proportion to their respective
liquidation preferences. In the event, however, that there are not sufficient
assets available to permit payment in full of the Common Adjustment, then such
remaining assets shall be distributed ratably to the holders of both classes
of Common Stock.

                  (c) In the event the corporation shall at any time after the
Rights Declaration Date (i) declare any dividend on Class A Common Stock
payable in shares of Class A Common Stock, (ii) subdivide the outstanding
Class A Common Stock, or (iii) combine the outstanding Class A Common Stock
into a smaller number of shares, then in each such case the Adjustment Number
in effect immediately prior to such event shall be adjusted by multiplying
such Adjustment Number by a fraction the numerator of which is the number of
shares of Class A Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Class A Common Stock that
were outstanding immediately prior to such event.

                  SECTION 7. CONSOLIDATION, MERGER, ETC.

                  In case the corporation shall enter into any consolidation,
merger, combination or other transaction in which the shares of Class A Common
Stock are exchanged for or changed into other stock or securities, cash and/or
any other property, then in any such case the shares of Series A Junior
Participating Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 1,000 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Class A Common Stock is changed or
exchanged. In the event the corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Class A Common Stock payable in
shares of Class A Common Stock, (ii) subdivide the outstanding Class A Common
Stock, or (iii) combine the outstanding Class A Common Stock into a smaller
number of shares, then in each such case the amount set forth in the preceding
sentence with respect to the exchange or change of shares of Series A Junior
Participating Preferred Stock shall be adjusted by multiplying such amount by
a fraction the numerator of which is the number of shares of Class A Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Class A Common Stock that were outstanding immediately
prior to such event.

                  The Certificate of Incorporation of the corporation shall
not be further amended in any manner which would materially alter or change
the powers, preferences or special rights of the Series A Junior Participating
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of a majority or more of the outstanding shares of Series A Junior
Participating Preferred Stock, voting separately as a class.

                  SECTION 10. FRACTIONAL SHARES.

                  Series A Junior Participating Preferred Stock may be issued
in fractions of a share which shall entitle the holder, in proportion to such
holders fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of

                  SECTION 3. COMMITMENT TO MAINTAIN FLOOR TRADING.

                  The corporation shall cause the Exchange, (i) as long as an
open outcry market is liquid (as defined below), to maintain for such open
outcry market a facility for conducting business, for the dissemination of
price information, for clearing and delivery and (ii) to provide reasonable
financial support (consistent with the calendar year 1999 budget levels
established by Chicago Mercantile Exchange, an Illinois not-for-profit
corporation, the predecessor of the Exchange) for technology, marketing and
research for open outcry markets. If an open outcry market is not liquid, as
determined by the board of directors, the board may determine, in its sole
discretion, whether such obligations will continue, and for how long, in
respect of such market. For purposes of this Section, an open outcry market
will be deemed "liquid" if it meets any of the following tests on a quarterly
basis:

                  (a) if a comparable exchange-traded product exists,
including electronic trading at the Exchange, the Exchange's open outcry
market has maintained at least 30% of the average daily volume of such
comparable product (including, for calculation purposes, volume from
exchange-for-physical transactions in such open outcry market); or

                  (b) if a comparable exchange-traded product exists and the
product trades exclusively by open outcry at the Exchange, the Exchange's open
outcry market has maintained at least 30% of the open interest of such
comparable product; or

                  (c) if no comparable exchange-traded product exists, the

                           (iv) On the 541st day after the IPO Date, all
         remaining Restricted Class A Shares shall automatically convert
         (without any action by the holder) into Unrestricted Class A Shares.

                           (v) Following each Notice of Secondary Sale
         Opportunity, each holder of Restricted Class A Shares may elect to
         include any or all of such holder's Restricted Class A Shares in the
         Secondary Sales Process contemplated by such notice by providing
         written notice of such election (a "Shareholder Election Notice"),
         including the number and class of shares elected to be included in
         such sale, to the secretary of the corporation within 20 days after
         the receipt of the Notice of Secondary Sale Opportunity. In the event
         that a Shareholder Election Notice is not received from a holder
         prior to such twentieth day, then such holder shall be deemed to have
         elected not to include any of such holder's shares in such Secondary
         Sale Process. Any Notice of Secondary Sale Opportunity shall be
         deemed to have been received by a holder three business days after
         deposited into the United States mail, if sent first class mail and
         addressed to the holder at such holder's address as it appears on the
         books and records of the corporation. Any Shareholder Election Notice
         shall be deemed received by the corporation when actually received by
         the secretary of the corporation at the principal place of business
         of the corporation in Chicago, Illinois or as otherwise provided in a
         notice by the corporation to holders of Restricted Class A Shares.
         Each shareholder shall be responsible for insuring that such holder's
         notice has been received by the corporation within the 20-day time
         period specified above. In the event that holders request to include
         more shares in the Secondary Sale Process than the board of directors
         determines in its sole discretion should be included in such sale,
         the board of directors shall develop, in its sole discretion, a
         mechanism for determining the Restricted Class A Shares that may be
         included in such sale; provided that preference shall be given to the
         class of Class A Common Stock that is scheduled to convert into
         Unrestricted Class A Shares in connection with the Secondary Sale
         Process. Each Shareholder Election Notice shall be irrevocable. Each
         holder's right to participate in a Secondary Sale Process is
         conditioned on such holder executing such agreements, including
         without limitation, underwriting agreements, placement agreements,
         agency agreements, custody agreements and powers of attorney, and
         providing such information as are required to complete the Secondary
         Sale Process. In the event that a holder fails to deliver such
         agreements and provide such information by the deadline specified in
         the Notice of Secondary Sale Opportunity, such holder shall be deemed
         to have elected not to participate in the Secondary Sale Process. The
         corporation shall not be responsible for the fees and expenses of any
         holder, including without limitation, broker commissions, agency fees
         and underwriting discounts and commissions which shall be the sole
         responsibility of each holder participating in the Secondary Sale
         Process. Nothing contained in this Subdivision 3 shall require the
         corporation to complete any Secondary Sales Process described in a
         Notice of Secondary Sale Opportunity, it being understood that the
         decision at any time to proceed shall be made in the sole discretion
         of the board of directors and that the board of directors may abandon
         any such Secondary Sales Process at any time.

                  (b) If, and only if, the IPO Date is not on or prior to
December 15, 2002, then the provisions of Paragraph (a) shall cease to apply
and shares of Class A-1 Common Stock, Class A-2 Common Stock, Class A-3 Common
Stock and Class A-4 Common Stock may not be Transferred (other than in a
Permitted Transfer) until such shares convert into Unrestricted Class A Shares
on the following dates:

                                            Date of Conversion
       Class                          into Unrestricted Class A Shares

       Class A-1 Common Stock               December 16, 2002
       Class A-2 Common Stock               March 16, 2003
       Class A-3 Common Stock               June 16, 2003
       Class A-4 Common Stock               September 16, 2003

                  (c) CONVERSION OF RESTRICTED CLASS A SHARES. Each share of
Class A-1 Common Stock, Class A-2 Common Stock, Class A-3 Common Stock and
Class A-4 Common Stock shall automatically convert (without any action by the
holder) into one Unrestricted Class A Share upon a Conversion Transfer or when
the transfer restrictions applicable to such share shall expire and such share
converts into an Unrestricted Class A Share as described in this Subdivision
3. Unrestricted Shares are not subject to restrictions on Transfer. Restricted
Class A Shares shall not convert into Unrestricted Class A Shares upon a
Non-Conversion Transfer.

                  (d) Any Person who takes shares of Class A-1 Common Stock,
Class A-2 Common Stock, Class A-3 Common Stock or Class A-4 Common Stock in a
Transfer that complies with the provisions of this Section 1 may treat the
endorsement on the certificate representing such shares, or the instrument of
Transfer accompanying such shares, or the written instrument specified in the
bylaws of the corporation with respect to uncertificated shares, as
authorizing such Person on behalf of the transferor to convert the shares for
the purpose of registering the Transfer to such Person of the shares of Class
A Common Stock issuable upon conversion, and may convert such shares of Class
A-1 Common Stock, Class A-2 Common Stock, Class A-3 Common Stock and Class A-4
Common Stock accordingly.

                  (e) Every certificate for shares of Class A-1 Common Stock,
Class A-2 Common Stock, Class A-3 Common Stock and Class A-4 Common Stock
shall bear a legend on its face reading as follows:

                           "The shares of Common Stock represented by this
                  certificate may not be Transferred to any person in
                  connection with a Transfer that does not meet the
                  qualifications set forth in the definition of "Permitted
                  Transfers" of the Certificate of Incorporation of this
                  corporation until the transfer restrictions applicable to
                  the shares represented by this certificate expire, and no
                  person who receives the shares represented by this
                  certificate in connection with a Transfer that does not meet
                  the qualifications prescribed by the definition of
                  "Permitted Transfers" of the Certificate of Incorporation of
                  this corporation prior to such time is entitled to own or to
                  be registered as the record holder of the shares of Common
                  Stock represented by this certificate. Each holder of this
                  certificate, by accepting the certificate, accepts and
                  agrees to all of the foregoing."

                  (f) Upon any conversion of shares of Class A-1 Common Stock,
Class A-2 Common Stock, Class A-3 Common Stock and Class A-4 Common Stock into
shares of Unrestricted Class A Shares, any dividend, for which the record date
or payment date is subsequent to the conversion, that has been declared on the
shares of Class A-1 Common Stock, Class A-2 Common Stock, Class A-3 Common
Stock or Class A-4 Common Stock so converted shall be deemed to have been
declared, and shall be payable, with respect to the Unrestricted Class A
Shares into or for which the shares of Class A-1 Common Stock, Class A-2
Common Stock, Class A-3 Common Stock or Class A-4 Common Stock are so
converted, and any such dividend that is declared on the shares of Class A-1
Common Stock, Class A-2 Common Stock, Class A-3 Common Stock and Class A-4
Common Stock payable in shares of Class A-1 Common Stock, Class A-2 Common
Stock, Class A-3 Common Stock and Class A-4 Common Stock shall be deemed to
have been declared, and shall be payable, in Unrestricted Class A Shares.

                  (g) Any shares of Class A-1 Common Stock, Class A-2 Common
Stock, Class A-3 Common Stock or Class A-4 Common Stock that have been
converted into Unrestricted Class A Shares will be retired with no further
action by the corporation, and will become authorized and unissued shares of
Class A Common Stock.

                  (h) The corporation at all times shall reserve and keep
available, out of its authorized but unissued Class A Common Stock, at least
the number of shares of Class A Common Stock that would become issuable upon
the conversion of all shares of Class A-1 Common Stock, Class A-2 Common
Stock, Class A-3 Common Stock and Class A-4 Common Stock then outstanding.

                  (i) In connection with any Transfer or conversion of any
shares of any class of Common Stock pursuant to or as permitted by the
provisions of this Section 1, or in connection with the making of any
determination referred to in this Section 1, neither the corporation nor any
director, officer, employee or agent of the corporation shall be liable in any
manner for any action taken or omitted in good faith.

                  (j) Except as permitted by this Section 1 of this
Subdivision 3, any proposed Transfer of shares of Class A-1 Common Stock,
Class A-2 Common Stock, Class A-3 Common Stock or Class A-4 Common Stock shall
be void.

         consist of 29 members, including 26 Equity Directors, one Class B-1
         Director, one Class B-2 Director and one Class B-3 Director. The
         terms of 20 Equity Directors shall expire at the annual meeting of
         shareholders to be held in April 2002 (the "April 2002 Annual
         Meeting"). The terms of the remaining six Equity Directors, one Class
         B-1 Director, one Class B-2 Director and one Class B-3 Director shall
         expire at the annual meeting of shareholders to be held in April
         2003.

                  (B) At the April 2002 Annual Meeting, the size of the board
         of directors of the corporation shall be reduced to 19 members by
         eliminating 10 Equity Director memberships. At the 2002 Annual
         Meeting, 10 directors shall be elected to serve two-year terms as
         follows:

                           (i) Seven directors shall be elected as Equity
         Directors;

                           (ii) Two directors shall be elected as Class B-1
         Directors; and

                           (iii) One director shall be elected as a Class B-2
         Director.

                  Of the nine directors whose terms expire at the annual

                           (i) Six directors shall be elected as Equity
         Directors;

         Director;

                           (iii) One director shall be elected as a Class B-2
         Director; and


                           (iv) One director shall be elected as a Class B-3
         Director.

                  (C) At each succeeding annual meeting of shareholders, the
         successors of the Class B-1 Directors, the Class B-2 Directors, any
         Class B-3 Director and the Equity Directors whose terms expire at
         that meeting shall be elected by the holders of the Class B-1 Common
         Stock, the Class B-2 Common Stock, the Class B-3 Common Stock, and
         the Common Stock voting as a single class, respectively. The
         directors so elected shall be elected for a term expiring at the
         annual meeting of shareholders held in the second year following the
         year of their election, and until their successors are duly elected
         and qualified and have accepted office, subject to death, resignation
         or removal from office. Any vacancy occurring in a directorship may
         be filled by the board of directors; PROVIDED, HOWEVER, that any
         vacancy occurring with respect to a Class B-1 Director, a Class B-2
         Director or a Class B-3 Director shall be filled from the candidates
         who lost for such position from the most recent election, with the
         candidates being selected to fill such vacancy in the order of the
         aggregate number of votes received in such previous election. Any
         persons so elected shall serve for the remaining term of his or her
         predecessor in office.

                  (D) No person shall be eligible for election as a Class B-1
         Director, a Class B-2 Director or a Class B-3 Director unless he or
         she shall own, or be recognized as the owner for the purposes of the
         Exchange of, at least one share of the class of Class B Common Stock
         entitled to elect such director.

                  (E) Any director may be removed from office at any time, but
         only for cause and only by the affirmative vote of the holders of at
         least two-thirds of the voting power of the shares entitled to elect
         such person as a director.

                  (F) The Equity Directors shall include two non-voting
         members until the April 2002 Annual Meeting at which time such
         directorships will be eliminated.

         ARTICLE SIX: The board of directors is hereby authorized to create
and issue, whether or not in connection with the issuance and sale of any of
its stock or other securities or property, rights entitling the holders
thereof to purchase from the corporation shares of Preferred Stock, Class A
Common Stock or securities of any other corporation. The times at which and
the terms upon which such rights are to be issued will be determined by the
board of directors and set forth in the contracts or instruments that evidence
such rights. The authority of the board of directors with respect to such
rights shall include, without limitation, determination of the following:

                  (A) The initial purchase price per share or other unit of
         the stock or other securities or property to be purchased upon
         exercise of such rights;

                  (B) Provisions relating to the times at which and the
         circumstances under which such rights may be exercised or sold or
         otherwise transferred, either together with or separately from, any
         other stock or other securities of the corporation;

                  (C) Provisions which adjust the number or exercise price of
         such rights or amount or nature of the stock or other securities or

         voting power of the then outstanding Common Stock, voting together as
         a single class.

of Incorporation to the contrary, the affirmative vote of at least two-thirds

representatives; PROVIDED, HOWEVER, that, except for proceedings to enforce
rights to indemnification, the corporation shall not be obligated to indemnify
any director or officer (or his or her heirs, executors or personal or legal
representatives) in connection with a proceeding (or part thereof) initiated

those conferred in this Article Eleven to directors and officers of the
corporation.

         The rights to indemnification and to the advance of expenses
conferred in this Article Eleven shall not be exclusive of any other right
which any person may have or hereafter acquire under this Certificate of
Incorporation, the bylaws of the corporation, any statute, agreement, vote of
shareholders or disinterested directors or otherwise.

         Any repeal or modification of this Article Eleven by the shareholders
of the corporation shall not adversely affect any rights to indemnification

or omissions occurring prior to such repeal or modification.

authorized, to the extent permitted by law, to take such action or actions as
the board of directors or such committee may determine to be reasonably
necessary or desirable to (A) encourage any person to enter into negotiations
with the board of directors and management of the corporation with respect to
any transaction which may result in a change in control of the corporation
which is proposed or initiated by such Person or (B) contest or oppose any
such transaction which the board of directors or such committee determines to
be unfair, abusive or otherwise undesirable with respect to the corporation
and its business, assets or properties or the shareholders of the corporation,
including, without limitation, the adoption of such plans or the issuance of
such rights, options, capital stock, notes, debentures or other evidences of
indebtedness or other securities of the corporation, which rights, options,
capital stock, notes, debentures or other evidences of indebtedness and other
securities (i) may be exchangeable for or convertible into cash or other
securities on such terms and conditions as may be determined by the board of

conditions, provisions and rights applicable to all other holders thereof.

         ARTICLE THIRTEEN: No action required to, or which may, be taken at an
