 2. Registration. 
  
 (a)    Registration Statements. 
  
 Promptly following the
closing of the purchase and sale of the securities contemplated by the Purchase Agreement (the “Closing Date”) but no later than thirty (30) days after the Closing Date (the “Filing Deadline”), the Company shall prepare and file
with the SEC one Registration Statement on Form S-3 (or, if Form S-3 is not then available to the Company, on such form of registration statement as is then available to effect a registration for resale of the Registrable Securities), covering the
resale of the Registrable Securities. Such Registration Statement also shall cover, to the extent allowable under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock
resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. The Company shall use its reasonable best efforts to obtain from each person who now has piggyback registration rights a waiver of those
rights with respect to the Registration Statement. The Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided in accordance with Section 3(c) to the Investors
and their counsel prior to its filing or other submission. If a Registration Statement covering the Registrable Securities is not filed with the SEC on or prior to the Filing Deadline, the Company will make pro rata payments to each Investor, as
liquidated damages and not as a penalty, in an amount equal to 1.5% of the aggregate amount invested by such Investor for each 30-day period or pro rata for any portion thereof following the date by which such Registration Statement should have been
filed for which no Registration Statement is filed with respect to the Registrable Securities; provided, however, that the Filing Deadline shall be extended and no fee shall accrue prior to the expiration of such extension (the
“Extension”) if and to the extent that the Registration Statement is not filed timely through no fault of the Company (i) at the request of the Required Investors or (ii) if the Required Investors have not so requested and any Investor is
in material breach of its obligations hereunder, provided that such Extension and non-accrual of fee shall apply only with respect to such breaching Investor and the Company shall otherwise be obligated to perform its registration obligations with
respect to all non-breaching Investors by the Filing Deadline or to pay such liquidated damages to such non-breaching investors in accordance with the foregoing and; provided, further, that in no event shall the Company be obligated to pay such
liquidated damages to more than one Investor in respect of the same Registrable Securities for the same period of time. Such payments shall be in partial compensation to the Investors, and shall not constitute the Investors’ exclusive remedy
for such events. Such payments shall be made to each Investor in cash. 
  
 (b)    Expenses.  The Company will pay all expenses associated with each registration, including filing and printing fees, counsel and accounting fees and expenses, 

 
 -2- 

 costs associated with clearing the Registrable Securities for sale under applicable state securities laws, listing fees, fees and expenses of
one counsel to the Investors (not to exceed $5,000) and the Investors’ reasonable expenses in connection with the registration, but excluding discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities
industry professionals with respect to the Registrable Securities being sold. 
  
 (c)    Effectiveness. 
  
 (i)    The Company shall
use commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable. The Company shall notify the Investors by facsimile or e-mail as promptly as practicable, and in any event, within twenty-four (24)
hours, after any Registration Statement is declared effective and shall simultaneously provide the Investors with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby. If (A)
a Registration Statement covering the Registrable Securities is not declared effective by the SEC within ninety (90) days after the Closing Date (other than solely as a result of an Extension) or (B) after a Registration Statement has been declared
effective by the SEC, sales cannot be made pursuant to such Registration Statement for any reason (including without limitation by reason of a stop order, or the Company’s failure to update the Registration Statement), but excluding the
inability of any Investor to sell the Registrable Securities covered thereby due to market conditions and except as excused pursuant to subparagraph (ii) below, then the Company will make pro rata payments to each Investor, as liquidated damages and
not as a penalty, in an amount equal to 1.5% of the aggregate amount invested by such Investor for each 30- day period or pro rata for any portion thereof following the date by which such Registration Statement should have been effective (the
“Blackout Period”); provided, however, that in no event shall the Company be obligated to pay such liquidated damages to more than one Investor in respect of the same Registrable Securities for the same period of time. Such payments shall
be in partial compensation to the Investors, and shall not constitute the Investors’ exclusive remedy for such events. The amounts payable as liquidated damages pursuant to this paragraph shall be paid monthly within three (3) Business Days of
the last day of each month following the commencement of the Blackout Period until the termination of the Blackout Period. Such payments shall be made to each Investor in cash. 
  
 (ii)    For not more than twenty (20) consecutive days or for a total of not more than forty-five (45) days in any twelve (12) month period, the
Company may delay the disclosure of material non-public information concerning the Company, by suspending the use of any Prospectus included in any registration contemplated by this Section containing such information, the disclosure of which at the
time is not, in the good faith opinion of the Company, in the best interests of the Company (an “Allowed Delay”); provided, that the Company shall promptly (a) notify the Investors in writing of the existence of (but in no event, without
the prior written consent of an Investor, shall the Company disclose to such Investor any of the facts or circumstances regarding) material non-public information giving rise to an Allowed Delay, and (b) advise the Investors in writing to cease all
sales under the Registration Statement until the end of the Allowed Delay. 
  
 (d)    Underwritten Offering.  If any offering pursuant to a Registration Statement pursuant to Section 2(a) hereof involves an underwritten offering, the Company shall 

 
 -3- 

  
 have the right to select an investment banker and manager to administer the offering, which investment
banker or manager shall be reasonably satisfactory to the Required Investors. 
  
 3.    Company Obligations.  The Company will use commercially reasonable efforts to effect the registration of the Registrable Securities in accordance with the terms hereof, and pursuant thereto
the Company will, as expeditiously as possible: 
  
 (a)    use commercially reasonable efforts

Investor deemed to be an underwriter); 
  
 (g)    use commercially reasonable efforts to (i)
prevent the issuance of any stop order or other suspension of effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order at the earliest possible moment; 
  
 (h)    prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify or cooperate with the
Investors and their counsel in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions requested by the Investors and do any and all other
commercially reasonable acts or things necessary or advisable to enable the distribution in such jurisdictions of the Registrable Securities covered by the Registration Statement;provided, however, that the Company shall not be required in

would not otherwise be so subject but for this Section 3(h), or (iii) file a general consent to service of process in any such jurisdiction; 
  
 (i)    use commercially reasonable efforts to cause all Registrable Securities covered by a Registration Statement to be listed on each securities exchange, interdealer quotation

 (j)    immediately notify the Investors, at any time when a Prospectus relating to Registrable Securities is required to be delivered under the 1933 Act, upon discovery that, or upon the happening of any event as
a result of which, the Prospectus included in a Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing, and at the request of any such holder, promptly prepare and furnish to such holder a reasonable number of copies of a supplement to or an amendment of such Prospectus as may be necessary so
that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus shall not include an untrue statement 

 
 -5- 

 of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing; and 
  
 (k)    otherwise use commercially reasonable

following the end of the fourth fiscal quarter that includes the effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the
90th day after the end of such fourth fiscal quarter). 
  
 (l)    With a view to making
available to the Investors the benefits of Rule 144 (or its successor rule) and any other rule or regulation of the SEC that may at any time permit the Investors to sell shares of Common Stock to the public without registration, the Company
covenants and agrees to: (i) make and keep public information available, as those terms are understood and defined in Rule 144, until the earlier of (A) six months after such date as all of the Registrable Securities may be resold pursuant to Rule

the sole purpose of enabling the Investors and such representatives, advisors and underwriters and their respective accountants 

 
 -6- 

 and attorneys to conduct initial and ongoing due diligence with respect to the Company and the accuracy of such Registration Statement.

unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the Investors, such advisors and representatives with the opportunity to accept or refuse to accept such
material nonpublic information for review and any Investor wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto. 
  
 5. Obligations of the Investors. 
  
 (a)    Each Investor shall furnish in writing to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by
it, as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request. At least five (5) Business Days prior to the
first anticipated filing date of any Registration Statement, the Company shall notify each Investor of the information the Company requires from such Investor if such Investor elects to have any of the Registrable Securities included in the
Registration Statement. An Investor shall provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of such Registration Statement if such Investor elects to have any of the Registrable
Securities included in the Registration Statement. 
  
 (b)    Each Investor, by its acceptance
of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of a Registration Statement hereunder, unless such Investor has notified the Company in writing
of its election to exclude all of its Registrable Securities from such Registration Statement. 
  
 (c)    In the event the Company, at the request of the Investors, determines to engage the services of an underwriter, such Investor agrees to enter into and perform its obligations under an underwriting
agreement, in usual and customary form, including, without limitation, customary indemnification and contribution obligations, with the managing underwriter of such offering and take such other actions as are reasonably required in order to expedite
or facilitate the dispositions of the Registrable Securities. 
  
 (d)    Each Investor agrees
that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay pursuant to Section 2(c)(ii) or (ii) the happening of an event pursuant to Section 3(j) hereof, such Investor will immediately discontinue
disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities, until the Investor’s receipt of the copies of the supplemented or amended prospectus filed with the SEC and declared effective
and, if so directed by the Company, the Investor shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies in the Investor’s possession of the Prospectus
covering the Registrable Securities current at the time of receipt of such notice. 

 
 -7- 

  
 (e)    No Investor may participate in any third party
underwritten registration hereunder unless it (i) agrees to sell the Registrable Securities on the basis provided in any underwriting arrangements in usual and customary form entered into by the Company, (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, and (iii) agrees to pay its pro rata share of all underwriting discounts and
commissions. Notwithstanding the foregoing, no Investor shall be required to make any representations to such underwriter, other than those with respect to itself and the Registrable Securities owned by it, including its right to sell the
Registrable Securities, and any indemnification in favor of the underwriter by the Investors shall be several and not joint and limited in the case of any Investor, to the proceeds received by such Investor from the sale of its Registrable
Securities. The scope of any such indemnification in favor of an underwriter shall be limited to the same extent as the indemnity provided in Section 6(b) hereof. 
  
 6.    Indemnification. 
  
 (a)    Indemnification by the Company.  The Company will indemnify and hold harmless each Investor and its officers, directors, members, employees and agents, successors and assigns, and each
other person, if any, who controls such Investor within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereof; (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state
or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or information herein called a “Blue Sky Application”); (iii) the omission
or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act
applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration; or (v) any failure to register or qualify the Registrable Securities included in any such Registration in any
state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company will undertake such registration or qualification on an Investor’s behalf (the undertaking of any underwriter chosen by the Company being
attributed to the Company) and will reimburse such Investor, and each such officer, director or member and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Investor or any such controlling person in writing specifically for use in such Registration Statement or Prospectus.

  
 (b)    Indemnification by the Investors.  In connection with any
registration pursuant to the terms of this Agreement, each Investor will furnish to the Company 

 
 -8- 

 in writing such information as the Company reasonably requests concerning the holders of Registrable Securities or the proposed manner of
distribution for use in connection with any Registration Statement or Prospectus and agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees,
stockholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any untrue statement of a material fact or
any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the
extent that such untrue statement or omission is contained in any information furnished in writing by such Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto. In no
event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Investor in connection with any claim relating to this Section 6 and the amount of any damages such holder has
otherwise been required to pay by reason of such untrue statement or omission) received by such Investor upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation. 

 
 (c)    Conduct of Indemnification Proceedings.  Any person entitled to indemnification
hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the
expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in
the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying
party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided,
further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely
affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one
separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. No indemnified person shall effect any settlement of any pending or threatened
proceeding for which indemnity is or may be sought from the Company hereunder without the prior written consent of the Company, which consent shall not be unreasonably withheld. 
  
 (d)    Contribution.  If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an
indemnified party or insufficient to hold 

 
 -9- 

 it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the
indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No
person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a
holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 6 and the amount of any damages such holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

                                    AGREEMENT

      THIS AGREEMENT, made and entered into this 7th day of February, 2000, by
and between THE CHICAGO MERCANTILE EXCHANGE ("Employer"), an Illinois not for
profit corporation, having its principal place of business at 30 South Wacker
Drive, Chicago, Illinois, and James J. McNulty ("Employee").

                                R E C I T A L S:

      WHEREAS, Employer wishes to retain the services of Employee in the
capacity of president and chief executive officer upon the terms and conditions
hereinafter set forth and Employee wishes to accept such employment;

      NOW, THEREFORE, in consideration of the mutual promises contained herein,
the parties mutually agree as follows:

      1.   EMPLOYMENT. Subject to the terms of the Agreement, Employer hereby
agrees to employ Employee during the Agreement Term as president and chief
executive officer and Employee hereby accepts such employment. Employee shall
report to the Employer's Board of Directors, or any successor to the Board of
Directors (hereinafter, "Board" shall mean the Board of Directors of Employer
and/or any successor thereto). The duties of Employee as president and chief
executive officer shall include, but not be limited to, the performance of
all duties associated with the management and operation of Employer,
including the execution of all policies formulated by the Board, the
selection and hiring of personnel for the various divisions and departments,
the training and establishing of duties and responsibilities of supervisory
personnel, and improvements in organization, accounting procedures and
financial policy for Employer. Further, and without limiting the generality
of the foregoing, Employee, pursuant to the direction of the Board, shall be
expected to successfully oversee and implement the "demutualization" of

<Page>

Employer, defined herein as the change of Employer from a member-owned not
for profit corporation to a stockholder-owned for-profit corporation.
Employee shall devote his full time, ability and attention to the business of
Employer during the Agreement Term, subject to the direction of the Board.

      Notwithstanding anything to the contrary contained herein, nothing in
the Agreement shall preclude Employee from participating in the affairs of
any governmental, educational or other charitable institution, engaging in
professional speaking and writing activities, and serving as a member of the
board of directors of a publicly held corporation (except for a competitor of
Employer), as long as the Board does not determine that such activities
interfere with or diminish Employee's obligations under the Agreement.
Employee shall be entitled to retain all fees, royalties and other
compensation derived from such activities, in addition to the compensation
and other benefits payable to him under the Agreement, but shall disclose
such fees to Employer.

      2.   AGREEMENT TERM. Employee shall be employed hereunder for a term
commencing on February 7, 2000 and expiring on December 31, 2003, unless
sooner terminated as herein provided ("Agreement Term"). The Agreement Term
may be extended or renewed by the mutual written agreement of the parties.

      3.   COMPENSATION.

            (a) SIGN-ON BONUS. Within thirty (30) days of Employee's
commencement of employment with Employer, Employer shall pay to Employee, in
a single lump sum, a sign-on bonus of two million dollars ($2,000,000), less
applicable deductions and withholdings, to compensate Employee for the loss
of benefits from Employee's previous employment.

                                       2
<Page>

            (b) ANNUAL BASE SALARY. During the Agreement Term, Employee shall
receive an Annual Base Salary of one million dollars ($1,000,000) payable
semi-monthly. Employer shall annually review the Annual Base Salary and, at
its sole discretion, may increase it from the level then in effect; in no
event shall the Annual Base Salary be reduced during the Agreement Term from
the level specified herein.

            (c) ANNUAL INCENTIVE BONUS. Employee shall have the opportunity
for an Annual Incentive Bonus for each calendar year during the Agreement
Term based on Employee's attainment of pre-established goals, as follows:

                  (i) The goals for the first calendar year of the Agreement
Term have been mutually agreed-upon by the parties, and are attached hereto
as EXHIBIT A and are incorporated herein by reference. During the remainder
of the Agreement Term, the goals for each coming calendar year shall be
determined solely by the Board, and shall be communicated, in writing, to
Employee at least thirty (30) days prior to the start of each calendar year.

                  (ii) The Annual Incentive Bonus shall not exceed the lesser
of one and one-half million dollars ($1,500,000) or, following
demutualization, ten percent (10%) of the Employer's Net Income, determined
in accordance with generally accepted accounting practices by the Employer's
regular outside certified public accountants.

                  (iii) The amount of the Annual Incentive Bonus for each
calendar year shall be as determined by the Board, in its sole discretion,
based on the Board's evaluation of Employee's attainment of the
pre-established goals. Prior to payment of an Annual Incentive Bonus to
Employee, the Board shall certify in writing that the pre-established goals,
and any other terms deemed material by the Board, have been attained.

                                       3
<Page>

                  (iv) Payment to Employee of any Annual Incentive Bonus
determined by the Board, shall be made in a single lump sum during the first
calendar quarter following the end of the calendar year.

            (d) NON-QUALIFIED STOCK OPTION AND LONG TERM INCENTIVE AWARD. As
of the date of Employee's commencement of employment with Employer, Employer
shall grant to Employee a Non-Qualified Stock Option and Long-Term Incentive
Award ("collectively referred to herein as the "Non-Qualified Stock Option")
in accordance with SUPPLEMENT A attached hereto and incorporated herein by
reference.

            (e) BENEFITS AND BENEFIT PROGRAMS. Employee shall be eligible to,
and shall, participate in all benefits and benefit programs offered from time
to time to the senior executives of Employer. This shall include, without
limitation, all insurance programs (e.g., medical, dental, vision, life,
accidental death and dismemberment and disability), paid holidays and 5 weeks
annual vacation, and pension, savings, cash balance, 401(k) and other
retirement plan or plans, all as may be in effect from time to time. In
addition, at Employer's expense, Employee shall be entitled to: (1) an annual
physical examination; (2) parking space at the principal location of
Employer, and (3) the amount of legal fees expended by Employee in connection
with the negotiation and execution of this Agreement, not to exceed
thirty-five thousand dollars ($35,000).

            (f) CEO PERQUISITES. Employee shall be eligible for such other
perquisites, paid for or reimbursed by Employer, that are customary for the
chief executive officer of a major financial institution, such as club
memberships, automobile allowance and reimbursement for professional
services. All such perquisites are subject to the approval of the Board's
Compensation Committee, or its designate or successor, which approval shall
not be unreasonably

                                       4
<Page>

withheld, and shall not exceed fifty thousand dollars ($50,000) for each
calendar year of the Agreement Term.

            (g) BUSINESS EXPENSES. Employer agrees to pay or promptly
reimburse Employee for all reasonable expenses incurred by Employee in
furtherance of, or in connection with, the transaction of the business of
Employer hereunder, subject to proper accounting by Employee and approval by
Employer.

      4.    DISABILITY.

            (a) In the event Employee is permanently disabled, as hereinafter
defined, for a continuous period of 6 months, Employer, in its sole
discretion, may terminate Employee's employment under the Agreement upon
written notice to Employee. In such event, Employee's Annual Base Salary
shall continue as provided in subparagraph (a) of paragraph 5.

            (b) Employee, for the purposes hereof, shall be deemed to be
"permanently disabled" when a mutually selected physician determines that as
a result of bodily injury or disease or mental disorder, he is so disabled
that he is prevented from performing the principal duties of his employment
with or without reasonable accommodation.

      5.    TERMINATION.

      Employer may terminate the employment of Employee under the Agreement
in the event that Employee shall die, or become permanently disabled, or for
"Cause" or "without Cause" as hereinafter defined, or upon expiration of the
Agreement Term, as set forth in subparagraphs (b) and (c) of this paragraph,
and Employee may terminate employment under the Agreement with or without
Good Reason, as hereinafter defined, as set forth in subparagraph (d) of this
paragraph. Except as set forth in the last sentence of this Section,
Employee's and his dependents' health,

                                       5
<Page>

dental and vision insurance shall be continued on the terms then in effect
(or as thereafter changed generally for the senior management of Employer)
until the earlier of (a) the end of the period of continuation of Employee's
Annual Base Salary, or (b) the date Employee obtains other employment and
becomes eligible for coverage under such employer's health insurance program.
To the extent applicable, continuation of group health insurance coverage for
Employee and his dependents pursuant to the provisions of Section 4980B of
the Internal Revenue Code of 1986, as amended, and Sections 6.02 through 6.07
of the Employee Retirement Income Security Act of 1974, as amended ("COBRA")
shall commence after expiration of the health insurance coverage provided
above. In the event of termination of Employee for Cause, or termination by
Employee other than for Good Reason, or termination upon expiration of the
Agreement, Employee's and his dependents' sole right to continued health
insurance coverage shall be pursuant to COBRA.

            (a) DEATH OR DISABILITY. In the event of termination of
Employee's employment hereunder due to death or Employee becoming permanently
disabled, Employer shall, for a period of six (6) months following such
termination, continue to pay Employee's Annual Base Salary, as then in
effect. Payments pursuant to this subparagraph (a) shall be made to Employee,
or to his estate or designated beneficiary in the event of his death.

      Any portion of the Non-Qualified Stock Option that is not vested prior
to termination on account of Employee's death or permanent disability shall
immediately vest on such termination. In the event of permanent disability,
during the remainder of the ten year period following the Grant Date (defined
in Supplement A), Employee shall be permitted to exercise any unexercised
portion of the Non-Qualified Stock Option. Any portion of the Non-Qualified
Stock Option that has not been exercised on the ten year anniversary of the
Grant Date shall be forfeited. As soon

                                       6
<Page>

as practicable following death, Employer shall pay to Employee's estate or
designated beneficiary cash equal to the excess of the fair market value of
the Covered Shares (referred to in Supplement A) subject to such exercise
over the aggregate exercise price for such Shares.

            (b) CAUSE OR EXPIRATION OF AGREEMENT TERM. If Employee's
employment hereunder is terminated by Employer for Cause, or upon expiration
of the Agreement Term, Employer shall pay to Employee in a single lump sum,
as soon as practicable after such termination or expiration, any and all
accrued but unused vacation pay and, accrued but unpaid Annual Base Salary,
and other amounts that have been earned but not paid to Employee as of the
date of such termination or expiration. If Employee is terminated for Cause,
the entire Non-Qualified Stock Option that has not been exercised by the date
of notice of termination for Cause shall be forfeited unless the Board, in
its sole discretion, determines otherwise. Upon expiration of the Agreement
Term, Employee shall be permitted to exercise any unexercised portion of the
Non-Qualified Stock Option during the ten year period following the Grant
Date. Any portion of the Non-Qualified Stock Option that has not been
exercised by the ten year anniversary of the Grant Date shall be forfeited.

      For purposes of this Agreement, "Cause" shall be deemed to exist if,
and only if:

            (i) Employee shall engage, during the performance of his duties
hereunder, in acts or omissions constituting dishonesty, intentional breach
of fiduciary obligation or intentional wrongdoing or malfeasance;

            (ii)  Employee shall intentionally disobey or disregard a lawful
and proper direction of the Board or Employer; or

                                       7
<Page>

            (iii) Employee shall materially breach the Agreement and such
breach by its nature is either incapable of being cured, or if capable of
being cured, remains uncured for more than thirty (30) days following receipt
by Employee of written notice from Employer specifying the nature of the
breach and demanding the cure thereof. For purposes of this clause (iii), a
material breach of the Agreement that involves inattention by Employee to his
duties shall be deemed a breach capable of cure.

      Without limiting the generality of the foregoing, the following shall
not constitute Cause for termination of Employee or the modification or
diminution of any of his authority hereunder: (a) any personal or policy
disagreement between Employee and Employer or any member of Employer or its
Board, or (b) any action taken by Employee in connection with his duties
hereunder or any failure to act, if Employee acted, or failed to act, in good
faith and in a manner Employee reasonably believed to be in and not opposed
to the best interest of Employer and Employee has no reasonable cause to
believe his conduct was unlawful.

      In the event of termination for Cause, Employer shall give Employee at
least thirty (30) days prior written notice, specifying in reasonable detail
the reason or reasons for Employee's termination.

            (c) WITHOUT CAUSE. Employee's employment may be terminated by
Employer at any time during the Agreement Term, at Employer's discretion and
without Cause, upon ninety (90) days advance written notice of same to
Employee. In this event, Employee shall continue to receive (1) his Annual
Base Salary for the remainder of the Agreement Term, and (2) one-third (1/3)
of the maximum Annual Incentive Bonus, payable semi-monthly, for the
remainder of the Agreement Term. Any portion of the Non-Qualified Stock
Option that is not vested prior to such

                                       8
<Page>

termination shall immediately vest on termination. During the ten year period
following the Grant Date, Employee shall be permitted to exercise any
unexercised portion of the Non-Qualified Stock Option. Any portion of the
Non-Qualified Stock Option that has not been exercised by the ten year
anniversary of the Grant Date shall be forfeited.

            (d) BY EMPLOYEE. Employee's employment with Employer may be
terminated by Employee at any time, after the first anniversary of this
Agreement, by the giving of ninety (90) days advance written notice of same
to Employer. In the event Employee terminates after the first anniversary of
this Agreement, Employer shall pay to Employee, as soon as practicable after
such termination, in a single lump sum, any and all Annual Base Salary, and
accrued but unused vacation pay, that have been earned but not paid to
Employee as of the date of termination. Employee shall forfeit the Annual
Incentive Bonus for the year during which he resigns, and he shall forfeit
any portion of the Non-Qualified Stock Option that is not vested prior to
termination. During the one hundred eighty (180) day period following such
termination, Employee shall be permitted to exercise any portion of the
Non-Qualified Stock Option that was vested prior to termination. Any portion
of the Non-Qualified Stock Option that has not been exercised by the one
hundred eighty first (181st) day following termination shall be forfeited. In
the event Employee attempts to terminate his employment prior to the first
anniversary of the Agreement, such act shall be treated as a material breach
of the Agreement by Employee under paragraph 5(b)(iii).

      In the event Employee terminates the Agreement pursuant to the above
after its first anniversary date with less than ninety (90) days advance
written notice of same to Employer, the parties acknowledge that Employer
will be damaged thereby, but that such damages will be

                                       9
<Page>

difficult to calculate. Accordingly, Employee will promptly pay to Employer,
or allow Employer to set off against any monies it may then owe to Employee,
as liquidated damages a sum equal to Employee's Annual Base Salary, on the
date of termination divided by 260 for each day Employee's notice of
termination hereunder is less than ninety (90) days.

      A termination by Employee for Good Reason shall entitle Employee to
those payments applicable to a termination without Cause, as set forth in
subparagraph (c) of this paragraph. For purposes of this paragraph, "Good
Reason" shall be deemed to exist if, and only if:

            (i)   The Employee's principal place of business is relocated
                  outside of the Chicago metropolitan area;

            (ii)  Employer fails to pay to Employee the agreed-upon
                  compensation or benefits;

            (iii) There is a demotion or significant diminution in Employee's
                  responsibilities or authorities under the Agreement sufficient
                  to constitute a constructive termination as presently defined
                  by Illinois law.

      The conditions set forth in (ii) and (iii) above shall constitute Good
Reason if such conditions remain uncured for more than thirty (30) days
following Employer's receipt of written notice from Employee advising of such
condition and demanding the cure thereof.

      6.    "WALKAWAY" OPTION.

      In the event Employer has not demutualized by December 31, 2000, the
Agreement may, within thirty (30) days thereafter, be terminated by either
Employee, if such failure is not the result of an intentional act by
Employee, or by Employer, by written notice of same to the other; provided,
however, that if Employer certifies in writing to Employee on or before
January 31,

                                       10
<Page>

2001, that demutualization has been delayed solely because a necessary
government action or ruling has not been received, and that Employer believes
in good faith that it will be received within ninety (90) days of the date of
Employer's certification hereunder, Employee shall not terminate hereunder
unless demutualization is not completed within such ninety (90) day period.
For purposes of the Agreement, the "Walkaway Period" shall mean the foregoing
period of time prior to demutualization, including the specified extensions
thereof, during which either party may, pursuant to this paragraph 6,
terminate the Agreement.

      In the event of termination of the Agreement under this paragraph,
Employee shall be paid the Annual Base Salary in effect prior to such
termination plus one-third (1/3) of the maximum Annual Incentive Bonus,
payable semi-monthly, for the remainder of the Agreement Term. Such payments
shall cease if and when Employee becomes employed by or becomes a consultant
to any organization engaged in trade execution and/or trade clearing.
Notwithstanding the preceding sentence, such payments shall not cease if
Employee becomes a member of the board of directors of any organization that
is not in direct competition with Employer. For purposes of this provision,
all stock exchanges shall be deemed to be in direct competition with Employer.

      During the Walkaway Period, Employee shall not exercise any portion of
the Non-Qualified Stock Option that has vested. In the event of termination
of the Agreement under this paragraph by either Employer or Employee, the
entirety of the Non-Qualified Stock Option, regardless of whether otherwise
vested or unvested, shall be forfeited.

      7.    CHANGE IN CONTROL.  For purposes of the Agreement, the term
"Change in Control" means the occurrence, of the events described in any of
subsections

(i), (ii), or (iii) below:

                                       11
<Page>

(i) The acquisition by any individual, entity or group (within the meaning of
Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of any voting
securities of the Employer entitled to vote generally in the election of
directors ("Voting Securities") if, immediately after such acquisition, such
Person beneficially owns fifty percent (50%) or more of the combined voting
power of the outstanding Voting Securities (the "Outstanding Employer Voting
Securities"). The foregoing provisions of this subsection (i) shall be
subject to the following:

(A)   The following shall not constitute a "Change in Control": (I) any
      acquisition by an employee benefit plan (or related trust) sponsored or
      maintained by Employer or any entity controlled by Employer (an "Employer
      Plan"); (II) any acquisition by an underwriter temporarily holding
      securities pursuant to an offering of such securities; or (III) any
      acquisition by any Person pursuant to a transaction which complies with
      subsections (ii)(A) and (ii)(B) of this definition.

(B)   For purposes of the foregoing provisions of this subsection (i), the
      following shall not be deemed to constitute an "acquisition" by any
      Person: (I) any acquisition directly from Employer (excluding any
      acquisition resulting from the exercise of an exercise, conversion, or
      exchange privilege unless the security being so exercised, converted, or
      exchanged was acquired directly from Employer); and (II) any acquisition
      by Employer of Voting Securities.

(ii) Consummation of (I) a reorganization, merger, consolidation, or other
business combination involving Employer or (II) the sale or other disposition
of more than fifty percent (50%) of the

                                       12
<Page>

operating assets of Employer (determined on a consolidated basis), other than
in connection with a sale-leaseback or other arrangement resulting in the
continued utilization of such assets (or the operating products of such
assets) by Employer (any transaction described in part (I) or (II) being
referred to as a "Corporate Transaction"); excluding, however, a Corporate
Transaction pursuant to which each of subsections (A) and (B) below are
applicable:

(A)   All or substantially all of the individuals and entities who are the
      beneficial owners, respectively, of the Outstanding Employer Voting
      Securities immediately prior to such Corporate Transaction beneficially
      own, directly or indirectly, more than fifty percent (50%) of the combined
      voting power of the then Outstanding Employer Voting Securities entitled
      to vote generally in the election of directors of the ultimate parent
      entity resulting from such Corporate Transaction (including, without
      limitation, an entity which, as a result of such transaction, owns
      Employer or all or substantially all of the assets of Employer either
      directly or through one or more subsidiaries) in substantially the same
      proportions as their ownership, immediately prior to such Corporate
      Transaction, of the Outstanding Employer Voting Securities, as the case
      may be.

(B)   No Person (other than Employer, any Employer Plan or related trust, the
      corporation resulting from such Corporate Transaction, and any Person
      which beneficially owned, immediately prior to such Corporate Transaction,
      directly or indirectly, fifty percent (50%) or more of the Outstanding
      Employer Voting Securities) will beneficially own, directly or indirectly,
      fifty percent (50%) or more of the then combined voting power of the then
      outstanding voting securities of such entity.

                                       13
<Page>

(iii) Approval by the shareholders of Employer of a plan of complete
liquidation or dissolution of the Employer.

      If during the Agreement Term there is both a Change in Control, and
Employee's employment is terminated by Employer, or by Employee for Good
Reason, during the two (2) years following such Change in Control, Employee
shall be entitled to the following:

            (a) A single lump sum severance payment to be paid by Employer
equal to the aggregate of (1) two (2) times the Annual Base Salary in effect
prior to such termination that would have been due Employee but for his
termination pursuant to this paragraph 7, plus (2) one and one-third (1 1/3)
times the maximum Annual Incentive Bonus that Employee would have been
eligible to receive but for his termination pursuant to this paragraph 7, for
the remainder of the Agreement Term; provided, however, that such severance
payment shall not exceed eight million dollars ($8,000,000), and may be
reduced to a lesser amount to the extent provided in subparagraph (b) next
below. This severance payment shall be made within ninety (90) days of the
date of such termination pursuant to this paragraph.

            (b)   If:

                  (i) any payment or benefit to which the Employee is
entitled from Employer, any affiliate, or trusts established by Employer or
by any affiliate (the "Payments," which shall include, without limitation,
the vesting of an option or other non-cash benefit or property) are more
likely than not to be subject to the tax imposed by Section 4999 of the
Internal Revenue Code of 1986, as amended ("Code") or any successor provision
to that section; and

                  (ii) reduction of the Payments to the amount necessary to
avoid the application of such tax would result in Employee retaining an
amount that is greater than the

                                       14
<Page>

amount he would retain if the Payments were made without such reduction but
after the application of such tax;

The Payments shall be reduced to the extent required to avoid application of
such tax. The Employee shall be entitled to select the order in which
Payments are to be reduced in accordance with the preceding sentence.
Determination of whether Payments would result in the application of the tax
under Code Section 4999, and the amount of reduction that is necessary so
that no such tax is applied, shall be made by the mutual agreement of the
parties or, in the absence of such agreement, by a mutually selected
independent certified public accounting firm, retained at Employer's expense.

            (c) Any portion of the Non-Qualified Stock Option that is not
then vested shall immediately vest. If the securities that Employee would
receive upon the exercise of the Non-Qualified Stock Option are of a class
that is not registered under Section 12 of the Securities Exchange Act of
1934, then the Non-Qualified Stock Option shall be exercisable by Employee
until the three-year anniversary of Employee's termination of employment with
Employer; provided that in no event shall the Non-Qualified Stock Option be
exercisable later than the ten-year anniversary of the Grant Date. If the
securities that Employee would receive upon the exercise of the Non-Qualified
Stock Option are of a class that is registered under Section 12 of the
Securities Exchange Act of 1934, then Employer shall file a Securities
Exchange Commission Form S-8 with respect to the sale of all of the
securities that would be deliverable to Employee upon the exercise of the
Non-Qualified Stock Option (in whole or in part) (the "Required Form S- 8")
before, or as soon as practicable after the termination of Employee's
employment with

                                       15
<Page>

Employer, and the Non-Qualified Stock Option shall be exercisable by Employee
until the latest to occur of:

(i)   the one-year anniversary of Employee's termination of employment with
      Employer;

(ii) the one-year anniversary of the date on which the Required Form S-8 becomes
     effective with respect to the exercise of the Non-Qualified Stock Option;
     or

(iii) the one-year anniversary of the date on which counsel to Employer renders
      an opinion to Employer and Employee that Employee is not an "affiliate"
      (as that term is defined in Rule 144 under the Securities Act of 1933)
      with respect to Employer or, if later, the date specified in such opinion
      as the date on which Employee will cease to be an "affiliate";

provided that in no event shall the Non-Qualified Stock Option be exercisable
later than the ten-year anniversary of the Grant Date. Any portion of the
Non-Qualified Stock Option that has not been exercised prior to the end of
the period of exercisability set forth in this paragraph (c) shall be
forfeited.

      8.    NONDISCLOSURE OF CONFIDENTIAL INFORMATION.

            (a) Employee acknowledges that Employer may disclose certain
confidential information to Employee during the Agreement Term to enable him
to perform his duties hereunder, and Employee hereby covenants and agrees
that, subject to subparagraph (b) of this Section, he will not, without the
prior written consent of Employer, during the Agreement Term (except in
connection with the proper performance of his duties hereunder) or at any
time thereafter, disclose or permit to be disclosed to any third party by any
method whatsoever any of the confidential information of Employer. For
purposes of the Agreement, "confidential information" shall include, but not
be limited to, any and all records, notes, memoranda, data,

                                       16
<Page>

writings, research, personnel information, customer information, clearing
members' information, Employer's financial information and plans in the
possession or control of Employer that have not been published or disclosed
to the general public or the commodities futures industry. If Employee fails
to comply with any provisions of this paragraph, which failure (i) is
inadvertent or unintentional, or (ii) occurs notwithstanding Employee's good
faith effort to comply with paragraph, or (iii) does not, and is not likely
to, result in material loss to Employer, then such failure shall not
constitute a violation of any provision, covenant or agreement of this
paragraph, for any purposes of this Agreement.

            (b) Clause (a), above, shall not be applicable if and to the
extent Employee is required to testify in a legislative, judicial or
regulatory proceeding pursuant to an order of Congress, any state or local
legislature, a judge, or an administrative law judge issued after Employee
and his legal counsel have, by all legal means, resisted such order. Employee
will promptly notify Employer, so that Employer will have sufficient time to
intervene or otherwise protect its interests, of the commencement of a
proceeding or action which might result in an order requiring the disclosure
of confidential information by Employee.

      9.   INDEMNITY. Except as precluded by law or regulation, Employer
shall indemnify, protect, defend and save Employee harmless from and against
any threatened, pending or completed action, suit or proceeding whether
civil, criminal, administrative or investigative, in which Employee is made a
party by reason of the fact that Employee is an officer, employee or agent of
Employer, or any judgment, amount paid in settlement (with the consent of
Employer), fine, loss, expense, cost, damage and reasonable attorney's fees
incurred by reason of the fact that Employee is an officer, employee or agent
of Employer, provided, however, that Employee acted

                                       17
<Page>

in good faith and in a manner he reasonably believed to be in the best
interests of Employer, and had no reasonable cause to believe his conduct was
unlawful. Employer, at its expense, shall have the right to purchase and
maintain insurance or fidelity bonds on behalf of Employee against any
liability asserted against him and incurred by him in his capacity as an
officer, employee or agent of Employer.

      10.  ARBITRATION; EQUITABLE REMEDIES. Any controversy or claim arising
out of or relating to the Agreement or the validity, interpretation,
enforceability or breach thereof, which is not settled by agreement of the
parties, shall be settled by arbitration conducted in the City of Chicago, in
accordance with the Labor Rules and Procedures of the American Arbitration
Association ("Association"), and judgment upon the award rendered in such
arbitration may be entered in any court having jurisdiction. The arbitration
shall be conducted before a single arbitrator selected by the parties. In the
event the parties cannot agree on any arbitrator, then the Association will
supply both parties with a list of seven (7) names. The parties will
alternatively strike one name until only one remains. First choice will be
determined by a coin toss, the winning party having the option of striking
first or second. All expenses of arbitration shall be borne equally by the
parties, except that each party shall bear its own attorney's fees. The
arbitrator shall have no power to amend, alter, add to or delete from the
Agreement.

      Employee acknowledges that Employer would be irreparably injured by a
violation of paragraph 8 and Employee agrees that Employer, in addition to
any other remedies available to it for such breach or threatened breach,
shall be entitled to a preliminary injunction, temporary restraining order,
or other equivalent relief, restraining Employee from any actual or
threatened breach of paragraph 8 pending, and in aid of, arbitration of the
dispute. If a bond is required to be

                                       18
<Page>

posted in order for Employer to secure an injunction or other equitable
remedy, the parties agree that such bond need not be more than a nominal sum.

      11.   RETURN OF PROPERTY. Upon Employee's last day of active work,
Employee hereby agrees to immediately turn over to Employer any keys, credit
cards, passes, and all notes, memoranda, records, documents, computer disks,
and all other information, no matter how produced or reproduced, kept by
Employee or in his possession or control, used in or pertaining to the
business of Employer, it being hereby acknowledged that all of said items are
the sole and exclusive property of Employer.

      12.   DEFENSE OF CLAIMS. During the period of his employment by
Employer, and continuing after the termination of his employment for a period
of three (3) years, Employee shall reasonably cooperate with Employer at its
request in the defense or prosecution of any claim that may be made by or
against Employer. Such cooperation shall include, without limitation, serving
as a witness at trial or hearing, being deposed, and preparation for same or
otherwise cooperating with Employer as determined to be necessary by Employer
at its sole discretion, for the defense or prosecution of a claim. For the
period after Employee terminates his employment with Employer, Employer shall
reimburse Employee for all reasonable expenses in connection therewith,
including travel expenses, and shall compensate him at a daily rate equal to
his Annual Base Salary on the date his employment with Employer terminated,
divided by 260, with days used for preparation, travel and other related
matters being included for purposes of determining the compensation due to
Employee. Less than full days shall be paid for by the hour, determined by
dividing the daily rate by eight. To the extent reasonably practicable,
Employer shall provide Employee with notice at least ten (10) days prior to
the date on which any such travel is required.

                                       19
<Page>

      13.   WAIVER OF BREACH. No waiver of either party hereto of a breach of
any provision of the Agreement by the other party, or of compliance with any
condition or provision of the Agreement to be performed by such other party,
will operate or be construed as a waiver of any subsequent breach by such
other party or any similar or dissimilar provisions and conditions at the
same or any prior or subsequent time. The failure of either party to take any
action by reason of such breach will not deprive such party of the right to
take action at any time while such breach continues.

      14.   ENTIRE AGREEMENT. The Agreement constitutes the entire agreement
between the parties concerning the subject matter hereof and supersedes all
prior and contemporaneous agreements, if any, between the parties relating to
the subject matter hereof.

      15.   COUNTERPARTS.  The Agreement may be signed in multiple
counterparts, each of which shall be deemed to be an original for all
purposes.

      16.   ACKNOWLEDGMENT BY EMPLOYEE. Employee represents that he is
knowledgeable and sophisticated as to business matters, including the subject
matter of the Agreement, that he has read the Agreement and that he
understands its terms. Employee acknowledges that, prior to assenting to the
terms of the Agreement, he has been given reasonable time to review it, to
consult with counsel of his choice, and to negotiate at arm's length with
Employer as to the contents. Employee and Employer agree that the language
used in the Agreement is the language chosen by the parties to express their
mutual intent, and that no rule of strict construction is to be applied
against either party hereto.

      17.   ASSIGNMENT, SURVIVAL OF AGREEMENT.

            (a)   This Agreement is personal to Employee and shall not be
assigned.

            (b) Employer may assign the Agreement without the consent of
Employee to any other entity who in connection with such assignment acquires
all or substantially all of the assets of Employer, or acquires a majority of
the voting rights of Employer, or into or with which Employer is merged or
consolidated. In the event of a merger, sale, reorganization or other Change
in Control (as defined in paragraph 7) of Employer, the Agreement shall be
binding upon, and inure to the benefit of, any successor to Employer.

            (c) Except as otherwise expressly provided in this Agreement, the
rights and obligations of the parties to the Agreement shall survive the
termination of Employee's employment with Employer.

      18.   NOTICE. All notices and communications required hereunder shall

                                  SUPPLEMENT A

      As of the date of employment (the "Grant Date"), Employer grants to
Employee this Non-Qualified Stock Option ("Option") upon the terms and
conditions set forth in this Supplement A. The Option may only be exercised
if Employer converts from an Illinois not-for-profit corporation to a
for-profit corporation. If Employer does not convert, Employee shall be
entitled to appreciation rights in lieu of the Option. The Option rewards
Employee for helping to increase the Value of Employer. The Option allows
Employee to acquire a basket of up to 2.5% of all classes of the Employer's
common stock, as of the date that Employer converts, for an exercise price
equal to 2.5% of the Value of the Employer on the Grant Date and to acquire a
basket of up to 2.5% of all classes of the Employer's common stock, as of the
date that Employer converts, for an exercise price equal to 3.75% of the
Value of the Employer on the Grant Date. The number of shares of each class
will be computed when the conversion becomes final and a Rider showing the
results of such computation will be attached to and become a part of this
Agreement. The number of shares and exercise price of a class of common stock
subject to the Option shall be adjusted as a result of an equity
restructuring to maintain the economic value of the Option. For purposes of
this Supplement A, an equity restructuring is a nonreciprocal transaction
between the Company and its shareholders, such as a stock dividend, spin-off,
stock split, reverse stock split, rights offering, or recapitalization
through a special, large nonrecurring dividend that causes the market value
per share of the stock underlying the Option to decrease or increase.

      The Option shall be a non-qualified stock option, not granted in
accordance with Section 422 of the Internal Revenue Code of 1986, as amended,
to purchase an indivisible package including each class of shares issued by
the Employer (the "Covered Shares").

<Page>

1.    The Option provides that, upon exercise with respect to the Covered Shares
      elected by Employee, Employee shall receive shares of Class A common
      stock, Class B common stock, cash, or a combination thereof, as determined
      by Employer in its sole discretion (except Employer shall not distribute
      more class B common stock than the amount included in the indivisible
      package comprising the Covered Shares elected by Employee), with an
      aggregate Fair Market Value equal to the Fair Market Value of the Covered
      Shares to which he would otherwise have been entitled upon exercise.

2.    The Options will be divided into two tranches, referred to as Tranche A
      and Tranche B. Each of Tranche A and Tranche B will include an equal
      number of the Covered Shares granted hereunder, that is, each tranche
      shall include a basket equal to 2.5% of each class of Employer's common
      stock.

3.    The exercise price with respect to all of the Covered Shares under Tranche
      A shall be 2.5% of the Value of Employer on the Grant Date. The exercise
      price with respect to all of the Covered Shares under Tranche B shall be
      3.75% of the Value of Employer on the Grant Date. If fewer than all the
      Covered Shares in a Tranche are exercised, the exercise price will be
      proportionately reduced.

4.    The "Value of Employer on the Grant Date" shall be equal to the sum of the
      prices for all memberships, with the price for any category of membership
      to be determined based on the average price of all actual transactions for
      that category of membership which took place during the six months prior
      to the Grant Date.

5.    Each Installment of Covered Shares of Tranche A and each installment of
      Covered Shares of Tranche B shall be exercisable on and after the Vesting
      Date for such Installment as described in the following schedule (but only
      if Employee's date of termination with Employer has not occurred before
      the Vesting Date):

6.    Notwithstanding the foregoing provisions of paragraph 5, the Option shall
      become fully vested and exercisable under the following circumstances: (i)
      the termination of Employee's employment with Employer by reason of the
      Employee's death or permanent disability pursuant to subparagraph 5(a) of
      the Agreement, (ii) termination by Employer without Cause pursuant to
      subparagraph 5(c) of the Agreement, (iii) termination by Employee for Good
      Reason pursuant to subparagraph 5(d) of the Agreement, and (iv) a Change
      in Control and termination as defined in paragraph 7(a) of the Agreement.

7.    At any time that a portion of the Option is exercisable, Employee may
      exercise such portion in whole or in part by filing a written notice with
      Employer accompanied by payment of the exercise price in accordance with
      Paragraph 13 of this Supplement A.

8.    The Option may be exercised on or after Employee's date of termination
      with Employer only as to those Covered Shares for which it was exercisable
      immediately prior to Employee's date of termination with Employer, or
      becomes exercisable on Employee's date of termination with Employer.

                                       3
<Page>

9.    Upon exercise of the Option, Employer shall distribute to Employee the
      Covered Shares subject to the exercise, or in lieu of the Covered Shares,
      shares of Class A common stock, Class B common stock, cash, or a
      combination thereof, as determined by Employer in its sole discretion
      (except Employer shall not distribute more class B common stock than the
      amount included in the indivisible package comprising the Covered Shares
      elected by Employee). Such payment of cash and/or shares of common stock
      shall be equal to the aggregate Fair Market Value of the Covered Shares
      subject to the exercise notice on the date of exercise. The Fair Market
      Value for the Class A and Class B Stock included in the Covered Shares, as
      of any date, shall be determined in the following manner:

                  (i)   If traded on an established exchange, Fair Market Value
            shall be the closing prices of such Stock on such exchange as of
            such date;

                  (ii) If such Stock is not traded on an established exchange as
            of such date, Fair Market Value shall be the average of the bid and
            ask prices for such Stock, where quoted for such Stock, as of the
            applicable date;

                  (iii) If no applicable price is available pursuant to clauses
            (i) or (ii) above, or if, in the mutual opinion of Employer and
            Employee, either or both of Class A and Class B Stock are thinly
            traded, an outside expert, mutually selected by Employer and
            Employee, shall establish the Fair Market Value of either or both.

10.   The Option shall not be exercisable after Employer's close of business on
      the last business day that occurs prior to the Expiration Date. The
      "Expiration Date" shall be the earlier to occur of: (i) the ten-year
      anniversary of the Grant Date or (ii) the date on which Employee is
      notified by Employer of Employee's termination for Cause; or (iii) the
      applicable date

                                       4
<Page>

following Employee's death, permanent disability or other termination pursuant
to paragraphs 5 or 7 of the Agreement.

11.   The Options and all rights thereunder will be non-transferable except with
      the written consent of the Compensation Committee of the Board.

12.   Shares of Class A Stock of Employer distributed pursuant to the exercise
      of the Option shall be transferable by Employee, subject to Employee being
      required to hold shares of such Stock, with a Fair Market Value equal to
      not less than three times Employee's Annual Base Salary, while employed by
      Employer as its Chief Executive Officer, subject to any applicable legal
      requirements, and subject to any lockup restrictions specified by
      Employer's banker.

13.   The Option may be exercised by Employee, by a legatee or legatees of the
      Option under Employee's last will, or by his executors, personal
      representatives or distributees, by delivering to the Secretary of
      Employer written notice of the percentage of Covered Shares with respect
      to which the Option is being exercised, accompanied by full payment to
      Employer of the exercise price of the Covered Shares being purchased under
      the Option. The exercise price of the Covered Shares purchased shall be
      paid in full by any of the following methods, or any combination thereof,
      selected by Employee, or his legatee or legatees, executors, personal
      representatives or distributees: (i) in cash, (ii) in Class A Stock valued
      at its Fair Market Value on the date of exercise, (iii) in Class B Stock
      valued at its Fair Market Value on the date of exercise, (iv) in cash by a
      broker-dealer to whom the holder of the Option has submitted an exercise
      notice consisting of a fully-endorsed Option (in such case, Employer shall
      pay all brokerage fees in connection with the exercise), (v) by agreeing
      to surrender a portion of the Option then exercisable,

                                       5
<Page>

      valued at the Fair Market Value of the Covered Shares minus the exercise
      price for such Covered Shares, or (vi) by directing Employer to withhold
      such number of shares of Covered Shares otherwise issuable upon exercise
      of the Option having an aggregate Fair Market Value on the date of
      exercise equal to the exercise price of the Option. The election by
      Employee pursuant to the preceding sentence must be made on or prior to
      the date of exercise of the Option and shall be irrevocable.

14.   As soon as reasonably practicable after exercise of the Option, and
      payment of the exercise price as provided above, Employer shall issue, in
      the name of Employee (or if applicable his legatees, executors, personal
      representatives or distributees) stock certificates representing the total
      number of Covered Shares or shares of common stock issuable pursuant to
      the exercise of the Option, provided that any Stock purchased by Employee
      through a broker-dealer shall be delivered to such broker-dealer in
      accordance with applicable government regulations.

15.   If Employer has not demutualized at the date that Employee gives notice of
      exercise, Employee shall receive appreciation rights in lieu of the
      Covered Shares to which he would have been entitled. In such case, no
      payment of the exercise price shall be due from Employee under paragraphs
      7 and 13 of this Supplement A, and no distribution shall be made to
      Employee in accordance with paragraphs 1, 9 and 14 of this Supplement A or
      otherwise. Instead, Employee shall be entitled to a cash payment equal to
      the excess of (i) the Fair Market Value (determined in accordance with
      paragraph 4 as of the date of exercise) of the percentage of Employer that
      would have been represented by Covered Shares subject to the exercise over
      (ii) the exercise price applicable to the Covered Shares

                                       6
<Page>

      that would have been subject to the exercise notice. The amount of such
      cash distribution (together with interest at the rate of LIBOR plus one)
      shall be made in three substantially equal installments on each of the
      one-year anniversary, the two-year anniversary, and the three-year
      anniversary of the exercise date.

fees is limited to $50,000.

                                SECOND AMENDMENT

            This is the Second Amendment ("Second Amendment") to the
Employment Agreement ("Agreement") entered into between James J. McNulty
("Employee") and Chicago Mercantile Exchange, Inc. ("Employer") which became
effective on February 7, 2000.

      1. The Agreement has previously been subject to the following
supplements and amendments that have been approved by the parties:

      (a)   Pursuant to a resolution of the Employer's Board of Directors dated
            August 30, 2000, the Board increased Employee's base salary by the
            amount of $4,036.46 in connection with the purchase of life
            insurance for Employee. (This document is attached as Annex I,
            hereto.)

      (b)   Pursuant to an Amendment (the "First Amendment") dated November 28,
            2000, the parties agreed upon performance goals for Employee and a
            schedule for the delivery of goals for subsequent years under the
            Agreement (This document is attached as Annex II, hereto.)

      (c)   Pursuant to the provisions of Supplement A to the Agreement, a Rider
            to the Agreement was to be prepared once the conversion of Employer
            from an Illinois not-for-profit corporation to a for-profit
            corporation had taken place. Such Rider was to show the number of
            shares of each class of Employer's stock that were the subject of
            the Non-Qualified Stock Option included in the Agreement. According
            to the terms of the Supplement, such Rider "...will be attached to
            and become a part of this Agreement." This Rider was prepared in
            February 2001. (This document is attached as Annex III, hereto. The
            first two pages of Annex III show the original Rider; the second two
            pages show updated information following the holding company
            reorganization.)

      2. Except to the extent otherwise amended expressly below, the
Agreement (which includes Supplement A), Annex I, Annex II and Annex III are
hereby ratified and confirmed and shall remain in full force and effect.

      3. Capitalized terms used but not defined in this Second Amendment
shall have the meaning set forth in the Agreement.

      4. Pursuant to the provisions of Annex II, the Board of Employer was to
have delivered in writing the performance goals for Employee for calendar
year 2002 on or

<Page>

before December 31, 2001. The 2002 goals were not delivered at that time,
although during 2002 Employer, Employee and Employer's outside advisors
continued to review various performance goals as well as methods and criteria
for measuring whether Employee met or exceeded those goals. A copy of the
final 2002 performance goals has been delivered to Employee and Employee
waives Employer's failure to deliver these goals in a timely manner. (The
2002 Performance Goals are attached as Annex IV, hereto). Employer has asked
Employee to suggest suitable performance goals and related metrics for
Employee for 2003. Employer has specified that there should be a minimum of
three and a maximum of six such performance goals for 2003 and that one of
the goals should involve starting a new business. Employee will deliver that
information to Employer in the beginning of December 2002. As provided in
Annex II, however, the ultimate obligation to deliver performance goals rests
with Employer, and Employer reconfirms its obligation to deliver Employee's
performance goals for 2003 prior to December 31, 2002.

      5. Employee and Employer have previously agreed that the Non-Qualified
Stock Option should be adjusted in the event Employer declares a significant
cash dividend. The last sentence of the first paragraph of Supplement A
refers to such an adjustment in general terms, and the following sentence
shall be added immediately thereafter.

      "In addition, a large nonrecurring dividend shall be deemed to have been
      paid (i) in the event that a nonrecurring cash dividend has been paid that
      is 1.5 or more times the prior calendar year's S&P 500 average dividend
      yield and (ii) to the extent by which such dividend distribution by
      Employer in fact exceeds such 1.5 times measure."

      6. Employee and Employer have previously agreed to limit Employer's
obligation to pay Employee's brokerage fees upon exercise of the
Non-Qualified Stock Option to a payment of not more than $50,000 in fees.
(Annex III, bottom of page 1.) From this point forward, Employee agrees to
pay all such fees and agrees that Employer shall not be obligated to pay any
such fees. Employer agrees that from this point forward it will limit itself
to delivering shares of its most widely held form of equity

                                       2
<Page>

which can be used for payment under the Non-Qualified Stock Option, the
shares of Class A common stock, or cash or a combination of the two upon an
exercise of the Non-Qualified Stock Option and to relinquish the right to
deliver shares of Class B common stock or other common stock upon such
exercise. Employee and Employer have also been advised by Employer's outside
accountants that the benefits associated with fixing certain expenses under
SFAS 123 (as described below in paragraph 8, hereof) will not be available if
Employer elects to deliver cash to Employee but may be available (assuming
other conditions including those in paragraph 8, below are met) if upon
exercise, Employer delivers to Employee solely shares of its widely held
equity (Class A common stock). The parties confirm, however, that while it
may be expected that Employer will deliver shares of Class A common stock
upon an exercise of the Non-Qualified Stock Option in order to secure such
benefits, the decision whether to deliver such shares, or cash, or a
combination thereof, remains exclusively with Employer. In particular, the
parties further confirm that the steps that they are taking and preparing to
take in this agreement in the hope and expectation of securing benefits
associated with fixing certain expenses under SFAS 123 do not alter
Employer's freedom to deliver a permitted form of consideration upon exercise
of the Non-Qualified Stock Option as Employer in its sole judgment shall
determine, whether or not specific accounting or other benefits to Employer
result from its decision.

      7. Paragraph 9 of Supplement A deals with Employer's obligation to
deliver cash and/or shares upon the exercise of the Option by Employee and
includes a procedure for determining the Fair Market Value for the Class A
and Class B Stock included in the Covered Shares as of particular dates. One
of the methods for determining such Fair Market Value is used if the shares
are traded on an established exchange, one method involves taking the average
of bid and ask and one involves the use of an outside expert. In order to
establish greater certainty about how Fair Market Value will be determined
and in order to conform the contractual terms to the accounting methodology
that Employer has used in describing the option and stock grants made to
other employees, the parties have agreed to modify Supplement A as follows:

                                       3
<Page>

      "Subparagraphs (ii) and (iii) of Paragraph 9 of Supplement A are hereby
      deleted and in their place the following are inserted:

      '(ii) if such stock is not traded on a national exchange as of such date,
      Fair Market Value shall be determined using the regular procedures
      employed by Employer's accounting department in valuing stock grants and
      in making related determinations, including the use of last sales price
      for such Stock in the event a sale has occurred within the preceding 15
      business days and the use of the average of the bid and ask prices for
      such Stock, where quoted for such Stock, as of the applicable date if no
      such sale has occurred within said 15 business days;

      '(iii) If the price of any Class of Stock is not established under
      subparagraph (i) and if either party certifies that the price that is
      calculated for such Stock pursuant to subparagraph (ii) is materially
      inconsistent with such Stock's Fair Market Value, the party so certifying
      may demand appointment of an independent expert, who shall be mutually
      selected by Employer and Employee, to establish the Fair Market Value of
      the Stock in question."

      8. Employer and Employee have discussed a further amendment to the
Non-Qualified Stock Option that might permit Employer to fix the expense
associated with the Non-Qualified Stock Option under Statement of Financial
Accounting Standards ("SFAS") 123. To achieve fixed expense under SFAS 123
would require (a) adoption of the proposed change in the relevant accounting
rules by the Financial Accounting Standards Board ("FASB") and (b) Employee's
willingness to relinquish his right to have his estate or designated
beneficiary receive a cash payment equal to "the excess of the fair market
value of the Covered Shares (referred to in Supplement A) subject to exercise
over the aggregate exercise price for such Shares" (the "Paragraph 5(a) death
benefit").

            In connection with the other agreements reflected herein and in
order to provide Employer and its shareholders the benefits that Employer's
outside accountants and financial advisors have indicated would be secured by
the ability to fix the expense related to the Non-Qualified Stock Option
instead of having the expense vary, in the event the proposed change is
adopted by FASB, Employer adopts SFAS 123, as amended, and Employer has
completed an underwritten public offering (which offering is now
contemplated), Employee agrees that (in the event of his death prior to the

                                       4
<Page>

expiration or other termination of the Non-Qualified Stock Option) his estate
or designated beneficiary shall no longer be entitled to receive the
Paragraph 5(a) death benefit in cash, provided said estate or designated
beneficiary shall instead have the continued right to exercise the
Non-Qualified Stock Option in the place of Employee through the end of the
term of said Option. (Any unexercised portion of the Non-Qualified Stock
Option shall expire at the end of the term of said Option.)

      9. This document is being executed by Employee and by a duly authorized
officer of Employer.

                                RESOLUTION OF THE
                               BOARD OF DIRECTORS

            WHEREAS, the Chicago Mercantile Exchange, by and through it Board
of Directors, has reviewed the merits of increasing the salary level for its
President, James McNulty, thereby permitting him to purchase life insurance
for himself;

            WHEREAS, the Board of Directors, by unanimous agreement has
determined that such a plan would, among other things, avoid substantial
financial loss to the Exchange should Mr. McNulty leave the employment of the
Exchange because of dissatisfaction with his life insurance benefits and
would further relieve Mr. McNulty of anxiety concerning the financial
security of his family in the event of his premature death or upon his
retirement;

            WHEREAS, Mr. McNulty has agreed to have such salary increases
applied to the purchase of life insurance policies on his life; and has
further agreed to advise the insurer that duplicate premium notices and
notice of policy cash withdrawals or policy loans will be provided to the
Exchange;

            NOW, THEREFORE, BE IT RESOLVED:

            RESOLVED, that in consideration of services rendered in the past
and those to be performed in the future, the Exchange hereby agrees to
increase the salary base of Mr. McNulty in amount equal to $4,034.46.

it is necessary to define the specific number of shares by class and exercise

      These individual exercise prices were determined assuming that the

      to April 2001 would all be converted to Class A common stock. In
      actuality, some of the Series B-5 stock was converted to Series B-4
      common stock. As a result, the sum of the individual exercise prices by
      class of stock is greater than the total exercise for Tranche A and
      this sum must be reduced by $73,019 as indicated above to arrive at the
      total exercise price for Tranche A of $21,840,547.

2.    The Non-Qualified Stock Option for a basket of up to 2.5% of all classes
      of common stock with an exercise price of 3.75% of the value of the
