limitation, the following:

     (a) CBOT shall use Ceres Proprietary Data only for the purposes authorized

     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

Amended Executive Employment Agreement, a copy of which is attached as
Exhibit A, is hereby terminated and replaced by this Agreement.

     Section 1.2. Resignation of Catania as Officer of the Company. Immediately
upon ratification of this Agreement by the Board or its duly authorized

Company and of any of its subsidiaries or affiliates. The letter shall be
submitted in the form attached as Exhibit B to this Agreement.

     Section 1.3. Duties and Responsibilities.

     (a) Following his resignation as an officer of the Company, Catania will
continue as an employee of the Company until June 6, 2003, and thereafter on a
month-to-month basis until terminated by either Catania or the Company.

     (b) Catania shall perform services for the Company relating to matters

     (d) Catania shall be classified as a regular full-time employee but shall
have the right to take one or more paid leaves of absence during such periods as
he is not performing services pursuant to (b) above, provided that no single
leave of absence shall be of more than 6 months' duration.

     Section 1.4. Early Retirement. The Company intends to offer Catania the
right to early retirement in accordance with an early retirement incentive
program under the Company's Qualified Pension Plan. Under such program, Catania
shall be eligible for all insurance coverages made available to other retirees
under the Company's group health plan. In the event that the Company should
henceforth amend the provisions of its group health plan to eliminate retiree
coverage, or shall be unable to offer Catania the right to participate in the
Company's group health plan as a retiree, Catania shall retain the option of
requiring that the Company provide him and his immediate family with medical and
dental coverage pursuant to the terms that would have been available to him if
he had retired prior to such elimination, with the cost to be paid by Catania as
set forth in section 2.06 of the Amended Executive Employment Agreement;
provided, that the obligation of the Company to provide continuing coverage
outside the Company's group health plan shall terminate in the event that
substantially equivalent coverage at no materially greater cost is made
available to Catania through a subsequent employer.

     Section 1.5. Right to engage in other business or employment. The Exchange
expressly understands and agrees that Catania may seek and secure additional
outside employment at any time following the execution of this Agreement, and
such employment will in no way affect any rights or entitlements to Catania
under this Agreement, provided; however,

                                       3
<PAGE>

Catania hereby agrees that all information, whether written or oral, relating to
the Company or received by the Company from a third party pursuant to
confidentiality restrictions, which was provided to Catania or to which Catania
became aware of while employed at the Company shall be considered proprietary
and confidential information of the Company ("Confidential Information").

     For purposes of this Agreement, Confidential Information shall include, but
not be limited to, any and all trade secrets and information regarding Company
products, customers, members, member firms, employees, business plans, finances,
and technological developments and programs. Confidential Information shall not
include information which: a) was known to Catania outside the terms of his
employment at the Company; b) is publicly known; c) has been disclosed to
Catania by a third party without a breach of any obligation of confidentiality;
or d) is disclosed pursuant to court order, duly authorized subpoena or
government authority.

     Section 1.6. Announcement of Resignation as Officer. On the day Catania
submits his resignation as an officer of the Company pursuant to this article,
the Board shall issue the press release attached hereto as Exhibit C. Any

                     Monetary Payments and Other Benefits
                            During Leaves of Absence

     Section 2.1. Salary. Until June 6, 2003, Catania shall continue to receive
his salary at the rate specified in Section 2.01 of the Amended Executive
Employment Agreement. After June 6, 2003, until his retirement Catania shall
receive such compensation as may be mutually agreed by Catania and the Company.

    Section 2.2. Certain insurance benefits for Catania. Until June 6, 2003, or
until the death of Catania, whichever occurs first, or until such later date
hereinafter set forth with respect to specified benefits, the Company shall
provide the following insurance benefits for Catania in the same amounts and on
the same terms as are available to other senior executives:

     (i) Health and dental insurance for Catania and his dependents, under the
Company's Health Plan and Dental Plan, until Catania's termination of employment
or retirement;

     (ii) Continued participation in the "Execu-Care" Medical Reimbursement and
Accidental Death; & Dismemberment programs in which Catania has participated as
Executive Vice President, Market and Product Development of the Company;

     (iii) Long-term disability insurance coverage;

     (iv) Continued insurance coverage on Catania's life in such amount as the
insurance that is currently provided to Catania by virtue of his employment at
the Company, whether through whole-life or term life policies (excluding any
insurance Catania's life as to which the beneficiary is the Company rather than
a beneficiary named by Catania);

                                       5
<PAGE>

     (v) Continued accidental death and dismemberment insurance of Catania in
such amounts and on such terms as are currently provided to Catania by virtue of
his employment at the Company.

     The insurance coverage required by this subsection 2.2 may be provided to
Catania through continued coverage of Catania through the Company's existing
plans, through purchase by the Company of new policies providing such coverage
to Catania, or by any other mutually agreeable method of providing such
coverage. As between Catania and the Company, the cost of providing such
coverage shall continue to be borne in the same manner for each coverage as it
is borne for other senior executives.

     (vi) In the event of Catania's death prior to the date he takes early
retirement pursuant to the provisions of section 1.4 of this Agreement, the
Company will provide medical and dental coverage to Catania's immediate family
on the same terms that are offered to retirees at such time, but with payment of
the cost of such coverage to be paid in accordance with section 2.06 of the
Amended Executive Employment Agreement; provided, that the obligation of the
Company to provide medical and dental coverage (other than as may be required
under COBRA) shall terminate in the event that substantially equivalent coverage
at no materially greater cost is made available to Catania's family through
another employer, remarriage of Catania's wife or otherwise.

     Section 2.3. Retirement benefits. The parties understand that Catania will
continue participating as a "covered employee" in the Company's Qualified
Savings Plan, Non-Qualified Savings Plan, Qualified Pension Plan, and Non-
Qualified Pension Plan so long as he continues as an employee of the Company.

                                       6

     (a) Credited service upon early retirement. The Company intends to offer
Catania early retirement to be effective as of June 6, 2003. Under the
anticipated early retirement program, the Company, in calculating his pension
(or his lump-sum distribution in lieu of pension) under the Qualified Pension
Plan, shall include in Catania's period of credited service all service through
December 11, 2004. If the terms of the Qualified Pension Plan are not amended to
permit including such time in the period of credited service through an early
retirement incentive program, the Company shall make a separate payment to
Catania calculated under proper actuarial principles to compensate him for the
difference in the amount of his pension under the Qualified Pension Plan
(calculated, in the event of his death, as if his date of death were a date of
termination of employment) and what that pension would have been had Catania
been credited with service through December 11, 2004, with benefits based on the
high 60-month compensation for periods of service ending on or prior to June 6,
2003. In such case, the Company shall disclose to Catania the basis on which it
makes this separate payment.

     (b) Payments on account of Benefit Plans in the event of Catania's death.
If the terms of any of Plan Documents referred to in this section 2.3 would have
called for payments to be made following Catania's death had he continued as the
Company's Executive Vice President, Market and Product Development, and died
before July 18, 2002, then such payments will be made in the event Catania dies
before June 6, 2003.

     Section 2.4. Legal fees. The Company shall reimburse Catania up to a
maximum of $5000, for the reasonable legal fees and expenses he has incurred as
a result of the negotiation and preparation of this Agreement.

CBOT Announces Resignation of Catania as Executive Vice President

Chicago, July 18 - The Chicago Board of Trade (CBOT(R)) today announced the
resignation of Patrick J. Catania as Executive Vice President for Business
Development, effective today. Catania played a leadership role in the
development of new products and markets, as well as the marketing of the
CBOT(R)'s agricultural, financial and equity products, during his 20-year tenure
at the exchange. He has been involved in the global futures industry for over 30
years.

Of his resignation, Catania said, "The Chicago Board of Trade is at a critical
juncture in its long and successful lifetime, and my stepping down provides
David Vitale with some much needed flexibility to structure the exchange in
order to meet the many challenges that lie ahead."

CBOT(R) President and CEO David J. Vitale said, "Pat has served our members and
member firms, customers and fellow employees with great distinction throughout
his years of service with the exchange. His experience and his knowledge of the
global commodity and financial markets have resulted in tremendous
contributions to the Chicago Board of Trade."

A member of many agricultural and financial market associations, Catania has
been a frequent speaker at industry meetings and conferences, and has
published many articles and several textbooks both independently and on behalf
of the CBOT(R). He maintains strong ties to the Asian and European markets, and
intends to provide consultancy services in marketing and product development to
the global financial services industry.
