<Page>



      Upon completion of the Specifications Documents as provided for in Section
3.1 hereof, SBF and CME shall agree upon a development schedule, setting forth
the deadlines for completion of the Modifications. In the event that CME and SBF

time as the Modified Software passes the Acceptance Test. SBF and CME agree that
time is of the essence in this Agreement and that the Modified Software shall
pass the final Acceptance Test by no later than May 31, 1998. In the event that
the failure to pass any Acceptance Test will, or threatens to, delay the Final
Cutover Date, SBF agrees, at its sole expense, to devote such additional
resources as may be necessary in order to permit CME to cutover to the
electronic trading system based on the Modified Software on the Final Cutover
Date.

      The Certificate of Acceptance shall not be unreasonably withheld. In the
event that CME does not deliver to SBF the Certificate of Acceptance referred to
above or the written notice referred to above within 15 days after the
notification by SBF to CME of successful completion of the Acceptance Test, the
completion shall for all purpose be conclusively presumed to have occurred and
CME shall be deemed for all purposes to have executed and delivered the
Certificate of Acceptance.

the name of CME and CME will co-operate with and assist SBF to the extent
that such co-operation may reasonably be required.

      7.2   DEFENSE OF CLAIMS AGAINST SBF.

      CME agrees that it shall indemnify SBF and save it harmless from an
Intellectual Property Claim incurred by or made against SBF alleging that the
exercise by the SBF of any of its rights arising from this Agreement infringes
any such intellectual property rights. SBF will promptly notify CME of any
Intellectual Property Claim that is threatened or brought against the SBF
alleging that the CME Enhancements and related documentation infringes any such
intellectual property rights. CME will defend and contest or settle any
Intellectual Property Claim, at its sole expense, in its own name and/or in the
name of the SBF and the SBF will cooperate with and assist CME to the extent
that such co-operation may reasonably be required.

      7.3   CLAIM FOR INFRINGEMENT.

      If the Modified Software or Licensed Materials are held by a final
judgment of a court of competent jurisdiction or is conceded by SBF in any
settlement to constitute an infringement of any intellectual property rights
and, as result thereof, the permitted use or modification of the Modified
Software or Licensed Materials is prohibited, SBF in addition to honoring the
foregoing indemnity, at its sole option and expense, shall forthwith either:
(a) procure from the owner of the intellectual property rights, the right for
CME and its Authorized Users to continue the permitted use and modification
of the Modified Software or Licensed Materials; or (b) further modify the
Modified Software or Licensed Materials, or the infringing part or parts
thereof, so that it is non-infringing or replace the same with a substitute
of equal quality approved by the CME, acting reasonably, such that the
Modified Software or Licensed Materials, or the substitute, shall perform to
the same or better level of performance.

      7.4   CLAIM FOR INFRINGEMENT.

      If CME Enhancements and related documentation are held by a final judgment
of a court of competent jurisdiction or is conceded by CME in any settlement to
constitute an infringement of any intellectual property rights and, as a result
thereof, the permitted use or modification of the CME Enhancements and related
documentation is prohibited, CME in addition to honoring the foregoing
indemnity, at its sole option and expense, shall forthwith either: (a) procure
from the owner of the intellectual property rights, the right for the SBF and
its Authorized Users to continue the permitted use of the CME Enhancements and
related documentation; or (b) modify the CME Enhancements and related
documentation, or the infringing part or parts thereof, so that it is
non-infringing


                                       12

<Page>

or replace the same with a substitute of equal quality approved by the SBF,
acting reasonably, such that CME Enhancements and related documentation or
the substitute shall perform to the same or better level of performance.

      7.5   LIMITATION ON INDEMNITY.

      In any claim for infringement against CME, SBF shall not be liable for any
infringement based on the use or combination of the Modified Software (or any
element of it) with programs not supplied by SBF if the infringement would have
been avoided in the absence of such use or combination.

      In any claim for infringement against SBF, CME shall not be liable for any
infringement based on the use or combination of the CME Enhancements (or any
element of them) with programs not supplied by CME if the infringement would
have been avoided in the absence of such use or combination.

      The foregoing paragraphs of this Article 7 state the entire liability of
the parties to each other for any loss and damage whatsoever as a result of the
infringement of any intellectual property rights.

                     ARTICLE 8 - LIMITATION OF LIABILITY

      8.1   EXTENT OF LIABILITY OF SBF.

      For any breach or default by SBF of any terms of this Agreement, CME's
exclusive remedy shall be the recovery of its direct damages. SBF's liability
for damages and regardless of the form or cause of action, whether in contract
or in tort, including negligence, shall not, in the aggregate, exceed the
amounts paid to SBF by CME for the Modifications.

      8.2   NO LIABILITY FOR CONSEQUENTIAL DAMAGES.

      In no event will either party be liable to the other or have a remedy for
the recovery of any special, indirect or consequential or incidental damages,
whether foreseeable or not, even if the applicable party has been advised of the
possibility thereof including, but not limited to, lost profits, lost revenues,
failure to realize expected savings, or other commercial or economic loss of any
kind.

      8.3   RESPONSIBILITIES OF CME.

      CME assumes full responsibility for use of the Licensed Software and the
Licensed Materials and any information entered, used and stored thereon,
including, without limitation, protection of data from viruses, or any
unintended modification, destruction or disclosure, and for the accuracy and
integrity of the results. SBF assumes no responsibility for CME's negligence or
failure to protect data from viruses, or any unintended modification,
destruction, or disclosure, or any damages caused by CME's failure to provide
properly functioning and compatible hardware, operating systems, or applications
software. SBF shall have no liability to CME for errors or defects in the CME
Enhancements or to any third party for any damages arising from CME's use of the
Licensed Software and the Licensed Materials.

      8.4   RESPONSIBILITIES OF THE SBF.

      SBF assumes full responsibility for its use of any CME Enhancements and
any information entered, used and stored thereon, including, without limitation,
protection of data from viruses, or any unintended modification, destruction or
disclosure, and for the accuracy and integrity of the results. CME assumes no
responsibility for SBF's negligence or failure to protect data from viruses, or
any unintended modification, destruction, or disclosure, or any damages caused
by SBF's failure to provide properly functioning and compatible hardware,
operating systems, or applications software.

  ARTICLE 9 - OWNERSHIP OF SOFTWARE AND CME ENHANCEMENTS AND CONFIDENTIALITY

      9.1   ACKNOWLEDGMENT OF OWNERSHIP BY SBF.

      CME acknowledges that the Licensed Software and Licensed Materials are the
property of SBF and that the only right which the CME obtains to the Licensed
Software and Licensed Materials is the right of use, modification, enhancement
and merger of the Licensed Software and Licensed Materials in accordance with
and subject to the terms of this Agreement.

      9.2   SBF OWNERSHIP AND USE OF MODIFICATIONS AND CME ENHANCEMENTS.

      During the term hereof, on each anniversary of the Effective Date, CME
shall, at its own expense, provide SBF with a copy of all Modifications and CME
Enhancements, related documentation, and any other changes made to the Modified
Software and Licensed Materials during the previous 12 month period; provided,
however, that in the event that SBF and CME have not reached a definitive
marketing agreement by September 15, 1997, respecting marketing of the Licensed
Software to third parties, SBF's use of the Modifications and CME Enhancements
will be limited to use in its own business.

      9.3   CME USE OF SBF ENHANCEMENTS.


                                       14

<Page>


      Subject to the terms of this Agreement, CME shall have the right to use
any enhancements made by SBF to the Licensed Software, whether made for SBF or
another licensee of the Licensed Software, provided that SBF has the legal right
to do so and further provided that SBF and CME shall agree on a reasonable fee
for such use, which fee shall be determined in good faith.

      9.4   INTELLECTUAL PROPERTY NOTICES.

      CME will ensure that all copyright, patent, proprietary and trade secret
notices of SBF will remain on the Licensed Software in an unmodified form, and
on all Licensed Materials.

      9.5   CONFIDENTIAL INFORMATION.

      CME acknowledges that the Licensed Software and Licensed Materials contain
proprietary and Confidential Information of SBF. CME agrees to safeguard the
Licensed Software and Licensed Materials by employing the highest degree of care
and diligence that it takes to safeguard its own most confidential information,
and such care shall not be any less than would be taken by a reasonable company
to safeguard such information. SBF acknowledges that CME may engage, with the
prior written approval of SBF, Persons to assist in the modification of the
Licensed Software and that CME may disclose the Licensed Software and Licensed
Materials to such Persons so long as CME has obtained from them a written
agreement to be bound by confidentiality provisions of equal scope to those in
this Agreement.

      However, with respect to the Persons listed in Exhibit 5 (which may be
amended from time to time by SBF), CME acknowledges that it will need the prior
written approval of SBF, which SBF shall not unreasonably withhold, in order to
use such subcontractors or any company directly or indirectly affiliated to such
subcontractors.

      The parties recognize that a breach of this Section 9.5 by the other party
may give rise to irreparable injury to the non-breaching party such that
remedies other than injunctive relief may not be adequate. Accordingly, the
non-breaching party has the right to seek from the "Tribunal de Grande Instance
de Paris" (France) equitable and injunctive relief to prevent the threatened or
actual unauthorized use of Licensed Software and Licensed Materials or
disclosure of the non-breaching party's Confidential Information.

      9.6   INFORMATION NOT PROTECTED.

      The protection to be accorded to Confidential Information to be disclosed
pursuant to this Agreement does not and will not extend to any information for
which it can be proved by documentary evidence produced by the receiving party:

            (a)  is already known to it or is in its possession before the
disclosure pursuant to this Agreement, free from any obligation to keep it
confidential;

            (b)  is or becomes publicly known through no wrongful act or
default of the receiving party;


                                       15

<Page>

            (c)  is received by a third Person without similar obligations of
confidence and without breach of this Agreement;

            (d)  is independently developed by the receiving party;

            (e)  is disclosed to a third party by the disclosing party
without similar restrictions on that third party's rights of disclosure;

            (f)  is approved for release by the prior written authorization
of the disclosing party; or

            (g)  constitutes General Know-How.

      9.7   NON-COMPETITION.

      In the event that CME determines to develop another electronic trading
system not based on the Licensed Software, CME agrees to give SBF *****
months prior written notice of its intention to develop such system, provided
that CME may begin using such new system prior to the expiration of such
***** month period. During such ***** month period, CME may continue to use
the Licensed Software and the Licensed Materials for its own use. CME may
utilize General Know-How in conjunction with its new development efforts;
including, without limitation, a joint development effort in conjunction with
another exchange. However, CME may not provide General Know-How to third
parties with whom it is not jointly developing a new electronic trading
system.

                      ARTICLE 10 - TERM AND TERMINATION

      10.1  TERM AND TERMINATION.

      The term of this Agreement shall commence on the Effective Date and shall
continue for 25 years, unless terminated: (a) by the mutual written agreement of
the parties; or (b) by an award of the arbitrators rendered pursuant to Section
11.2 for a material breach of the Agreement which remains uncured after 30 days
following receipt of notice of such failure from the other party.

      10.2  RETURN MATERIALS.

      On any termination of this Agreement, other than a termination caused by
SBF's breach of this Agreement, CME shall return the Licensed Software and
Licensed Materials to SBF and shall certify, under the hand of a duly authorized
officer of CME, that the original and all copies of the Licensed Software and
Licensed Materials have been given up to SBF, all records or copies of the
Licensed Software or Licensed Materials in computer memory have been destroyed,
and that no copies of any part of the Licensed Software and Licensed Materials,
in any form, remain in possession or control of CME.

      10.3  RIGHTS OF ACTION.


                                       16

<Page>

      Termination of this Agreement will not affect any right of action of
either party arising from anything which was done or not done, as the case may
be, prior to such termination taking effect.

                          ARTICLE 11 - GENERAL

      11.1  FORCE MAJEURE.

      Neither party shall be liable for delay or failure in performance, except
the payment of money, resulting from acts beyond the control of such party,
including, but not limited to Acts of God, acts of war, fire, flood, or other
disaster, act of government, strike, lockout, communication line or power
failures.

      11.2  GOVERNING LAW; ARBITRATION; AND CHOICE OF JURISDICTION.

            (a) The construction, validity and performance of this Agreement
will be governed in all respects by the laws of France.

            (b) Except as may arise pursuant to Section 9.5 hereof, all
disputes and claims arising in connection with this Agreement, whether during
or after the term hereof, shall be submitted for a final determination to
arbitration under the then-current Rules of Conciliation and Arbitration of
the International Chamber of Commerce ("ICC"), as may be modified or
supplemented by this Section 11.2. Such arbitration shall be held in Paris,
France conducted in the English language. The arbitration panel shall consist
of three arbitrators. SBF and CME expressly agree that the arbitrators shall
permit each party: (1) to request, and shall compel each party to produce for
the other party reasonably in advance of any hearing, any relevant documents,
evidence or witnesses; and (2) to call and question any witness, including
any expert witness, and to cross-examine any witness called by its opponent.
The award of the arbitrators shall be final and shall constitute the
exclusive remedy of SBF and CME for all claims, counterclaims, issues or
accounting presented or plead to the arbitrators. Each award by the
arbitrators shall: (1) be granted and paid in United States Dollars; (2) if
such award includes payment from one party to another, include interest at
the rate of one percent per month from the date of breach or other violation
of the Agreement until the date the award is fully paid; and (3) include the
cost of the arbitration and the prevailing party's reasonable attorneys' fees
and expenses. Judgment upon the final arbitral award may be entered in any
court that has jurisdiction thereof. Any additional costs, fees or expenses
incurred by the prevailing party in enforcing the arbitral award shall be
charged against and paid by the party that resists its enforcement.

      11.3  ASSIGNMENT OR DELEGATION.

      Neither party may assign its rights or delegate its obligations hereunder
to any third parties without the prior written consent of the other party.

                                  AMENDMENT

This is Amendment Number 1 to the Central Services System (NSC) Software License
and Development Agreement between Societe des Bourses Francaises ("SBF") and
Chicago Mercantile Exchange ("CME"), which became effective on June 5, 1997. The
CLEARING 21/NSC Marketing Letter of intent, which also became effective on June
5, 1997, is hereby terminated.

Capitalized terms used but not defined in this Amendment Number 1 shall have the
meaning set forth in the Central Services System (NSC) Software License and
Development Agreement; or, if any such capitalized term is likewise not therein
defined, shall have the meaning set forth in an agreement entitled CLEARING 21
Software Marketing and Distribution Agreement.

This Amendment is effective this 24th day of February, 1998, which is the same
effective date as the effective date of the CLEARING 21 Software Marketing and
Distribution Agreement. Except as set forth herein, all provisions of the
Central Services System (NSC) Software License and Development Agreement shall
remain unchanged and in full force and effect.

Article 4 of the Central Services System (NSC) Software License and Development
Agreement is hereby amended to conclude with a new Section 4.4, as set forth
below.

"4.4  NSC LICENSE FEE.

SBF has accepted certain additional license rights in the CLEARING
21-Registered Trademark- system pursuant to the terms of the aforesaid
CLEARING 21 Software Marketing and Distribution Agreement, and certain
further license rights as a consequence of the execution simultaneously
therewith of Amendment Number 1 to the CLEARING 21 Software License and
Development Agreement between SBF and CME dated June 5, 1997. In
consideration of the extension of SBF's license rights in the CLEARING 21
system as set forth above, of the special obligations agreed to by CME in
section 4.6 of the aforesaid CLEARING 21 Software Marketing and Distribution
Agreement relating to the services of a full-time marketing specialist, and
of the positive promotional impact that disclosure of CME's decision to adopt
the Central Services Systems is anticipated to have on other derivatives
exchanges considering licensing of the Central Services Systems from SBF, SBF
agrees to pay CME ***** of any gross license fee received by SBF for any
license of the Central Services Systems to a derivatives exchange in the
United States, and ***** of any gross license fee received by SBF for any
license of the Central Services Systems to a derivatives exchange elsewhere
in the world."

may modify the hardware configuration."

3. Article 4 of the Central Services System (NSC) Software License and
Development Agreement, as amended on February 24, 1998 (Amendment Number 1), is
hereby amended to conclude with new Sections 4.5, 4.6 & 4.7, as set forth below.

      "4.5  REPORTING REQUIREMENTS.

      (a) REPORTING OF FEES. Within fifteen calendar days of the end of each
calendar quarter beginning with the first calendar quarter in which a payment is
due to CME hereunder, SBF shall send CME a written report for such calendar
quarter and cumulatively for the calendar year a detailed account of all fees
due to CME under this Agreement including: identification of each Sublicensee by
name and specific site or location; authorized type/model and number of
computers; date of sublicense agreement; date of installation of each such
Licensed Software; effective dates of maintenance agreements; effective dates
and details of any events that impact or affect fees owed by SBF to CME under
this Agreement (e.g., implementation or deployment of the Licensed Software by a
third party); and, the breakdown of SBF's and CME's respective shares of fees
and charges accrued and paid (expressed in both the currency of payment and in
U.S. dollars). Upon request, SBF shall promptly provide CME with copies of all
invoices relevant to the calculation of fees due.

      (b) REPORTING OF EXECUTED LICENSE AGREEMENTS. Additionally, SBF shall be
required to notify CME in writing of all license agreements executed under this
Agreement. Such notification shall occur within fifteen calendar days of the
execution of the license agreement and shall include a copy of the fee and
payment schedule associated with each such license agreement.

      4.6   PAYMENTS OF FEES.

      Any payment due from SBF to CME under this shall be paid to CME at the
date of the quarterly report of fees required by Section 4.5(a). SBF agrees to
make payments due hereunder to CME in U.S. dollars, at the then-prevailing
exchange rate on the date payment is effected by SBF. If local law or accounting
principles require that SBF pay only in response to an invoice, SBF shall
prepare an invoice in the appropriate form and forward it to CME for signature
and presentation. SBF shall supply sufficient detail to explain its calculation
of the payments owing to CME and will provide copies of relevant


                                       2

materials upon request. Failure by SBF to make payments to CME within 45
calendar days of the end of each calendar quarter shall constitute a material
breach of this Agreement.

      4.7   RIGHT TO AUDIT RECORDS.

      CME shall have the right, upon reasonable notice, by independent audit and
at its own expense, to audit SBF's records as they affect amounts payable to CME
under this Agreement. If any such audit results in a determination that there
has been an under payment greater than 15% of the payment actually made, then
the costs of the audit shall be borne by SBF."
