Committee shall consist of not less than two (2) Directors. The members of the

the Board. It is intended that each member of the Committee shall qualify as (a)

<PAGE>

so qualify, actions taken by the Committee prior to such determination shall be
valid despite such failure to qualify.

     3.2. Authority and Action of the Committee. It shall be the duty of the
Committee to administer the Plan in accordance with the Plan's provisions. The
Committee shall have all powers and discretion necessary or appropriate to
administer the Plan and to control its operation, including, but not limited to,

and to grant Awards, (b) prescribe the form, amount, timing and other terms and
conditions of each Award, (c) interpret the Plan and the Award Agreements, (d)
adopt such procedures as it deems necessary or appropriate to permit
participation in the Plan by eligible Employees, (e) adopt such rules as it
deems necessary or appropriate for the administration, interpretation and
application of the Plan, and (f) interpret, amend or revoke any such procedures
or rules. A majority of the Committee shall constitute a quorum. The acts of the
Committee shall be either (i) acts of a majority of the members of the Committee
present at any meeting at which a quorum is present or (ii) acts approved in
writing by all of the members of the Committee without a meeting.

on such terms and conditions as it may provide, may delegate all or any part of
its authority and powers under the Plan to one or more Directors and/or officers
of the Company; provided, however, that the Committee may not delegate its
authority or power with respect to (a) any officer of the Company with regard to
the selection for participation in this Plan of an officer or other person
subject to Section 16 of the 1934 Act or decisions concerning the timing,
pricing or amount of an award to such an officer or person or (b) any Award that
is intended to satisfy the requirements applicable to "qualified performance-
based compensation" under section 162(m) of the Code.

     3.4. Decisions Binding. All determinations, decisions and interpretations

                          SHARES SUBJECT TO THE PLAN

     4.1. Number of Shares. Subject to adjustment as provided in Section 4.3,
2.6 million Shares shall be available for grants of Awards under the Plan. In
the case of an Award that is intended to qualify as "qualified performance-based
compensation" under section 162(m) of the Code, the maximum number of Shares
with respect to which Options or SARs or a combination thereof may be granted
during any Fiscal Year to any person shall be 1.5 million, subject to adjustment
as provided in Section 4.3 and calculated, in the case of any Shares other than
Class A Shares, by using the number of
                                       7
<PAGE>

Class A Shares that is equivalent to the number of such Shares under the table
of Share equivalencies contained in the Agreement and Plan of Merger dated as of
March ___, 2000, between CME Transitory Co. and the Company. Shares awarded
under the Plan may be either authorized but unissued Shares, authorized and
issued Shares reacquired and held as treasury Shares or a combination thereof.

    4.2. Lapsed Awards. To the extent that Shares subject to an outstanding
Option (except to the extent Shares are issued or delivered by the Company in
connection with the exercise of a tandem SAR) or other Award are not issued or
delivered by reason of the expiration, cancellation, forfeiture or other
termination of such Award or by reason of the delivery or withholding of Shares
to pay all or a portion of the exercise price of an Award, if any, or to satisfy
all or a portion of the tax withholding obligations relating to an Award, then
such Shares shall again be available under this Plan.

    4.3. Adjustments in Awards and Authorized Shares. In the event of any
merger, reorganization, consolidation, recapitalization, liquidation, stock
dividend, split-up, Share combination, or other similar change in the corporate
structure of the Company affecting the Shares, the Committee may adjust the
number, class and series of securities available under the Plan, the number,
class, series and purchase price of securities subject to outstanding Awards,
and the numerical limits of Sections 4.1, 7.1 and 8.2.1 in such manner as the
Committee in its sole discretion shall determine to be appropriate to prevent
the dilution or diminution of such Awards. If any such adjustment would result
in a fractional security being (a) available under this Plan, such fractional
security shall be disregarded, or (b) subject to an outstanding Award under this
Plan, the Company shall pay the holder of such Award, in connection with the
first vesting, exercise or settlement of such Award in whole or in part
occurring after such adjustment, an amount in cash determined by multiplying (i)
the fraction of such security (rounded to the nearest hundredth) by (ii) the
excess, if any, of (A) the Fair Market Value on the vesting, exercise or
settlement date over (B) the Exercise Price, if any, of such Award.

Options may include Incentive Stock Options, Non-Qualified Stock Options, or a
combination thereof; provided, that no Incentive Stock Option shall be granted
more than ten years after the date this Plan is adopted by the Board.

    5.2. Award Agreement. Each Option shall be evidenced by an Award Agreement
that shall specify the Exercise Price, the expiration date of the Option, the
number, class and, if applicable, series of Shares to which the Option pertains
(provided that Incentive Stock Options may be granted only with respect to Class
A Shares), any conditions to the exercise of all or a portion of the Option, and
such other terms and conditions as the

                                       8
<PAGE>

Committee, in its discretion, shall determine. The Award Agreement pertaining to
an Option shall designate such Option as an Incentive Stock Option or a Non-
Qualified Stock Option. Notwithstanding any such designation, to the extent that
the aggregate Fair Market Value (determined as of the Grant Date) of Shares with
respect to which Options designated as Incentive Stock Options are exercisable
for the first time by a Participant during any calendar year (under this Plan or
any other plan of the Company, or any parent or subsidiary as defined in section
424 of the Code) exceeds the amount (currently $100,000) established by the
Code, such Options shall constitute Non-Qualified Stock Options. For purposes of
the preceding sentence, Incentive Stock Options shall be taken into account in
the order in which they are granted.

    5.3. Exercise Price. Subject to the provisions of this Section 5.3, the
Exercise Price with respect to Shares subject to an Option shall be determined

     Stock Option, the Exercise Price may be equal to or greater than one
     hundred percent (100%) of the Fair Market Value of a Share on the Grant
     Date, as shall be determined by the Committee in its sole discretion.

     Option, the Exercise Price shall be not less than one hundred percent
     (100%) of the Fair Market Value of a Share on the Grant Date; provided,
     however, that the Exercise Price with respect to a Ten Percent Shareholder
     shall not be less than one hundred-ten percent (110%) of the Fair Market
     Value of a Share on the Grant Date.

    5.4. Expiration of Options.

         5.4.1. Expiration Dates. Each Option shall terminate not later than as
     of the expiration date specified in the Award Agreement pertaining to such
     Option; provided, however, that the expiration date with respect to an
     Incentive Stock Option shall not be later than the tenth anniversary of its
     Grant Date and the expiration date with respect to an Incentive Stock
     Option granted to a Ten Percent Holder shall not be later than the fifth
     anniversary of its Grant Date.

     Agreement pertaining to an Option, each Option granted to a Participant
     shall terminate no later than the first to occur of the following events:

          Participant's Termination of Service by reason of the Participant's
          Retirement (provided, that the portion of any Incentive Stock Option
          exercised more than three months after such Termination of Service
          shall be deemed to be a Non-Qualified Option);

               (d) The date of the Participant's Termination of Service for
          Cause; or

               (e) The expiration date specified in the Award Agreement

         5.4.3. Death of Employee. Unless otherwise specified in the Award
     Agreement pertaining to an Option, if a Participant to whom an Option has
     been granted dies while an Employee but prior to the expiration,

     shall become exercisable in full upon the Participant's death and shall be
     exercisable thereafter until the earlier of (a) the expiration of one (1)

discretion. After an Option is granted, the Committee, in its sole discretion,
may accelerate the exercisability of the Option.

    5.6. Method of Exercise. Options shall be exercised by the Participant's
delivery of a written notice of exercise to the Secretary of the Company (or its
designee), setting forth the number of Shares with respect to which the Option
is to be exercised, accompanied by full payment of the Exercise Price with
respect to each such Share. The Exercise Price shall be payable to the Company
in full in cash or its equivalent (including, but not limited to, by means of, a
broker-assisted cashless exercise). The Committee, in its sole discretion, also
may permit exercise (a) by tendering previously acquired Shares having an
aggregate Fair Market Value at the time of exercise equal to the aggregate
Exercise Price of the Shares with respect to which the Option is to be
exercised, or (b) by any other means which the Committee, in its sole
discretion, determines to both provide legal consideration for the Shares, and
to be consistent with the purposes of the Plan.

As soon as practicable after receipt of a written notification of exercise and
full payment for the Shares with respect to which the Option is exercised, the
Company shall deliver to the Participant, as determined by the Committee in its
sole discretion, either (i) Share certificates (which may be in book entry form)
for such Shares, (ii) Share certificates for Class A Shares, (iii) cash or (iv)
a combination thereof, in each case with an aggregate Fair Market Value equal to
the Fair Market Value of the Shares with respect to which the Option is
exercised.

    5.7. Restrictions on Share Transferability. The Committee may impose such
restrictions on any Shares acquired pursuant to the exercise of an Option as it
may deem advisable, including, but not limited to, restrictions related to
applicable Federal securities laws, the requirements of any national securities
exchange or system upon which Shares are then listed or traded, or any blue sky
or state securities laws.

determined by multiplying: (i) The amount by which the Fair Market Value of a
Share on the date of exercise exceeds the Exercise Price specified in the Award
Agreement pertaining to such SAR; times (ii) The number of Shares with respect
to which the SAR is exercised.

Restricted Stock shall be held by the Company as escrow agent during the
applicable Period of Restriction, together with stock powers or other
instruments of assignment (including a power of attorney), each endorsed in
blank with a guarantee of signature if deemed necessary or appropriate by the
Company, which would permit transfer to the Company of all or a portion of the
Shares subject to the Restricted Stock Award in the event such Award is
forfeited in whole or in part. Upon the grant of a Bonus Stock Award, subject to
the Company's right to require payment of any taxes, a certificate or

<PAGE>

     performance-based compensation" under section 162(m) of the Code, the
     Committee shall set restrictions based upon the achievement of Performance
     Goals.

          7.4.3. Legend on Certificates. The Committee, in its discretion, may
     legend the certificates representing Restricted Stock during the Period of
     Restriction to give appropriate notice of such restrictions. For example,
     the Committee may determine that some or all certificates representing
     Shares of Restricted Stock shall bear the following legend:

"The sale or other transfer of the shares of stock represented by this
certificate, whether voluntary, involuntary, or by operation of law, is subject
to certain restrictions on transfer as set forth in the Chicago Mercantile
Exchange Omnibus Stock Plan, and in a Restricted Stock Agreement. A copy of the
Plan and such Restricted Stock Agreement may be obtained from the Secretary of
the Chicago Mercantile Exchange."

     7.5. Removal of Restrictions. Shares of Restricted Stock covered by a
Restricted Stock Award made under the Plan shall be released from escrow as soon
as practicable after the termination of the Period of Restriction (and the
satisfaction or attainment of any applicable Performance Goals) and, subject to

and shall be subject to the same restrictions on transferability and
forfeitability as the Shares of Restricted Stock with respect to which they were
paid.

     7.8. Return of Restricted Stock to Company. On the date set forth in the
Award Agreement, the Restricted Stock for which restrictions have not lapsed
shall revert to the Company and again shall become available for Awards under
the Plan.

     7.9. Termination of Service.

          7.9.1. Disability, Retirement and Death. Unless otherwise specified in
     the Award Agreement pertaining to a Restricted Stock Award granted to a
     Participant, upon the Participant's Termination of Service by reason of

     Period, and for the forfeiture of all or a portion of such Award if
     specified Performance Goals are not satisfied or met during the Performance
     Period.

resulting from any claim, action, suit, or proceeding to which he or she may be
a party or in which he or she may be involved by reason of any good faith action
taken or good faith failure to act under the Plan or any Award Agreement, and
(b) from any and all amounts paid by him or her in settlement thereof, with the
Company's approval, or paid by him or her in satisfaction of any judgment in any
such claim, action, suit, or proceeding against him or her, provided he or she
shall give the Company an opportunity, at its own expense, to handle and defend
the same before he or she undertakes to handle and defend it on his or her own
behalf. The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under the

all of the business or assets of the Company.

     9.5. Beneficiary Designations. If permitted by the Committee, a Participant
under the Plan may name a beneficiary or beneficiaries to whom any vested but

Sections 7.6 and 7.7, no Participant (nor any beneficiary) shall have any of the
rights or privileges of a stockholder of the Company with respect to any Shares
issuable pursuant to an Award (or exercise thereof), unless and until
certificates representing such Shares shall have been issued, recorded on the
records of the Company or its transfer agents or registrars, and delivered to

the Company, an amount sufficient to satisfy federal, state, local and foreign
taxes (including, but not limited to, the Participant's FICA and SDI
obligations) required to be withheld with respect to such Award (or exercise
thereof). Notwithstanding any contrary provision of the Plan, if a Participant
fails to remit to the Company such withholding amount within the time period
specified by the Committee (in its discretion), the Participant's Award may, in
the Committee's discretion, be forfeited and in such case the Participant shall
not receive any of the Shares subject to such Award.

a Fair Market Value equal to the amount required to be withheld.

     9.10. Deferrals. The Committee, in its sole discretion, may permit a
Participant to defer receipt of the payment of cash or the delivery of Shares

     9.11. Change of Control. (a)(1) Notwithstanding any provision in this Plan
or any Award Agreement, in the event of a Change of Control pursuant to

converted pursuant to such Change of Control. In the event of any such
substitution, the purchase price per share in the case of an Option and the base
price in the case of an SAR shall be appropriately adjusted by the Committee

holder thereof, and each such Award shall immediately be canceled by the
Company, and the holder shall receive, within ten days of the occurrence of a
Change of Control, a cash payment from the Company in an amount equal to (i) in

price offered to stockholders of the Company in any transaction whereby the
Change of Control takes place or (B) the Fair Market Value of a Share on the
date of occurrence of the Change of Control, over the purchase price per Share
subject to the Option, (ii) in the case of an SAR other than a tandem SAR, the
number of Shares then subject to such SAR, multiplied by the excess, if any, of
the greater of (A) the highest per Share price offered to stockholders of the
Company in any transaction whereby the Change of Control takes

Restricted Stock Award or Performance Share Award, the number of Shares or the
number of Performance Shares, as the case may be, then subject to such Award,
multiplied by the greater of (A) the highest per Share price offered to
stockholders of the Company in any transaction whereby the Change of Control

Exchange Act to assure that any cash payment in accordance with the foregoing to
such person is made in compliance with Section 16 and the rules and regulations

Award or the delivery of Shares thereunder, such Award shall not be exercised or
settled and such Shares shall not be delivered unless such listing,
registration, qualification, consent, approval or other action shall have been
effected or obtained, free of any conditions not acceptable to the Company. The
Company may require that certificates evidencing shares delivered pursuant to
any Award made hereunder bear a legend in indicating that the ale, transfer o
other disposition thereof by the holder is prohibited except in compliance with
the Securities Act of 1933, as amended, and the rules and regulations
