business operations and affairs of Ceres which has been marked or which is
declared to be confidential in writing prior to its disclosure, shall be and
shall remain the sole and exclusive property of Ceres and constitute valuable
proprietary information of Ceres.  CBOT agrees to treat the Ceres Proprietary
Data in the manner herein prescribed and to take such additional steps as are
reasonably necessary to protect the confidentiality of Ceres Proprietary Data
and Ceres proprietary interests therein, including, but not by way of
limitation, the following:

     (a) CBOT shall use Ceres Proprietary Data only for the purposes authorized
by this Agreement and shall not make any copies of, reproduce, or disclose,

uses to protect its own proprietary data and shall promptly report to Ceres any
conduct by CBOT's present or former employees or agents of which CBOT becomes
aware relating to Ceres Proprietary Data inconsistent with this Agreement or
Ceres' proprietary interests therein, and take such reasonable steps as may be
required to terminate such conduct.

and reasonable attorneys' fees) incurred by the other as a result of any failure
by the party, its employees or agents to maintain the confidentiality of the

instructions or their contractual, employment or agency relationship with the
party has been terminated.

the other party upon reasonable notice adequate records to demonstrate

     6.5  Acknowledgement of Irreparable Injury.  Each party hereby acknowledges
that use of the other party's proprietary Data in a manner contrary to the
provisions of this Agreement would cause the other party irreparable harm for
which money damages could not make the injured party whole, and hereby consents,
to the full extent that it is able to do so, to any order entered by any court
of competent jurisdiction prohibiting it from such violation of this Agreement.

     6.6  Materials Not Considered Confidential.  Notwithstanding any other
provision in this Agreement to the contrary, information and data presently in
the public domain or which subsequently enters the public domain other than
through violation of this Agreement shall not be subject to any restrictions
under this Agreement, nor shall either party have any liability to the other for
the use or disclosure thereof.  The party asserting the applicability of this
Section 6.6 will have the burden of proof with respect thereto.

                           SECTION 7 - MISCELLANEOUS
                           -------------------------

     7.l  Counterparts.  This Agreement may be executed in several counterparts,
each of which shall be deemed to be an original but all of which taken together
shall constitute one single agreement between the parties hereto.

     7.2  Headings.  The Section headings used herein are for reference and
convenience only and shall not enter into the interpretation hereof.

     7.3  Relationship of Parties.  Ceres, in furnishing services to CBOT, is
providing Faciliities Management Services only as an independent contractor.
Ceres does not undertake by this Agreement or otherwise to perform any
obligation of CBOT, whether regulatory or contractual.  Ceres has the sole right
and obligation to supervise, manage, contract, direct, procure, perform or cause
to be performed, all work to be performed by Ceres hereunder unless otherwise
provided herein. Ceres may employ subcontractors, including CBOT/Eurex Alliance,
L.L.C. and Deutsche Borse Systems AG, to provide any of the services covered by
this Agreement.

     7.4  Approvals, Consents, etc. Where any approval, acceptance or consent by
either party is required by any provision of this Agreement, such action shall
not be unreasonably delayed or withheld.

     7.5  Force Majeure.  Ceres shall be excused from performance hereunder for
any period Ceres is prevented from performing any services pursuant hereto, in
whole or in part, as a result of an act of God, war, civil disturbance, or other
cause beyond its reasonable control, including shortages or fluctuations in
electrical power, heat, light or air conditioning, and such non-performance
shall not be a default hereunder or a ground for termination hereof so long as
the same is temporary in nature and does not unreasonably interfere with CBOT's
business and operations.

<PAGE>
                                                                               8

     7.6  Severability.  If any provision of this Agreement is declared or found
to be illegal, unenforceable or void, then both parties shall be relieved of all
obligations arising under such provision, but if such provision does not relate
to the payments to be made to Ceres by CBOT and if the remainder of this
Agreement shall not be materially affected by such declaration or finding, then
each provision not so affected shall be enforced to the extent permitted by law.

     7.7  Attorneys' Fees.  If any legal action or other proceeding is brought
for the enforcement of this Agreement, or because of an alleged dispute, breach,
default or misrepresentation in connection with any of the provisions of this
Agreement, the prevailing party shall be entitled to recover reasonable
attorneys' fees and other costs incurred in that action or proceeding, in
addition to any other relief to which it may be entitled.

     7.8  Waiver.  No delay or omission by either party hereto to exercise any
right with respect to this Agreement shall impair any such right or be construed
to be a waiver thereof.  A waiver by either of the parties hereto of any of the
agreements to be performed by the other or any breach thereof shall not be
construed to be a waiver of any succeeding breach thereof or of any other
agreement herein contained.  All remedies provided for in this Agreement shall
be cumulative and in addition to and not in lieu of any other remedies available
to either party at law, in equity or otherwise.

     7.9  Choice of Law and Jurisdiction.  This Agreement shall be governed by
the internal laws and not the choice of law provisions of the State of Illinois.
Any suit arising out of a dispute arising concerning this Agreement may only be
brought in a state or federal court sitting in Chicago, Illinois and the parties
agree that no other court shall have jurisdiction or venue.

     7.10 Entire Agreement. This Agreement, together with each Exhibit attached
          hereto, constitutes the entire agreement between the parties hereto
          with respect to the subject matter hereof and shall supercede in its
          entirety the CBOT/Ceres License Agreement between the parties dated
          October 22, 1992, and the Amended and Restated CBOT/Ceres License
          Agreement dated May 15, 1998. No change, waiver or discharge hereof
          shall be valid unless in writing and executed by the party against
          whom such change, waiver or discharge is sought to be enforced.

     7.11 The parties acknowledge that they are in the process of reorganizing.
          In connection with this reorganization, Ceres may assign its rights
          and obligations under this Agreement to Electronic Chicago Board of
          Trade, Inc.
