Dear
Mr. Shakotko: 

        This
letter serves to amend Section 9 of the License Agreement ("Agreement") between Standard & Poor's, a division of The McGraw-Hill Companies, Inc.
("S&P") and the Chicago Mercantile Exchange ("CME"), dated September 24, 1997. The amended text of Section 9 of the Agreement is provided below with additions underscored. 

        (b)  Calculation
and Dissemination of Index Values. S&P or its agent shall compute and, in a manner reasonably satisfactory to CME, disseminate
to CME, the value of each of the S&P Stock Indices at least once every fifteen seconds during normal trading hours. The foregoing shall be at S&P's expense, except that S&P shall not be obligated to
pay for any hardware, software, communications or similar expenses associated with the receipt by CME of S&P Stock Index values. S&P, or its agent, shall provide CME each trading day with respect to
each S&P Stock Index licensed to CME hereunder a special opening quotation for use in settling Indexed Contracts based on such S&P Stock Index as well as the percentage of underlying stocks that have
opened trading that day in the primary market or that have resumed trading after a trading halt in the primary market. With respect to the S&P Euro Index and S&P Euro Plus Index, S&P, or
its agent, shall provide CME, on the days of determination of the Final Settlement Price as designated by CME, with a special ***** quotation for use in settling contracts based on these Indices. The
special ***** quotation shall be based on *****. Of the *****, shall constitute the special ***** quotation. 

        Subject
to Section 13 hereof, S&P shall use its best efforts: (1) to ensure the correct and timely calculation and dissemination of the S&P Stock Indices;
(2) maintain a backup to verify the calculation of the S&P Stock Indices on a continuing basis; (3) take extra precautions to verify the accuracy of the daily closing index values; and
(4) inform CME each day of the closing numbers for each of the S&P Stock Indices as soon as practicable after the closing of trading of the underlying stocks. 

        Please
review these proposed changes at your earliest convenience and acknowledge your acceptance by signing in the space provided below. Do not hesitate to contact Mr. John
Labuszewski at 312-466-7469 in the CME Research Department should you have any questions or comments regarding this matter.

400 Contract, lists for trading Indexed Contracts based on the S&P MidCap 400 Index having a contract multiplier *****, CME shall pay S&P a per-trade license fee for the ***** equal to the
license fee payable hereunder for the S&P MidCap 400 Contract at the time the ***** is listed, multiplied ***** minus the percentage reduction in the size of the contract multiplier between the
original S&P MidCap 400 Contract and the *****. 

        Except
as modified hereby, all of the terms and conditions of the Agreement shall remain in full force and effect.

Dear
Mr. Shakotko: 

        Pursuant
to Section 2(e) of the license agreement ("Agreement") between the Chicago Mercantile Exchange ("CME") and Standard & Poor's ("S&P"), dated September 24,
1997, as amended, CME requests that Appendix 1 and Appendix 2 of the Agreement be amended to include the S&P/TOPIX 150 INDEX. 

        It
is agreed, however, that (i) Section 3 of the Agreement shall not apply to the S&P/TOPIX 150 Index and its associated trademarks, in that S&P's license to CME in
connection therewith shall be nonexclusive and (ii) since "TOPIX" is a trademark of the Tokyo Stock Exchange, it shall for purposes of the Agreement be treated the same as the "BARRA" trademark
insofar as the parties' representations, warranties, rights, covenants and agreements are concerned, and S&P hereby represents to CME that it has obtained the Tokyo Stock Exchange's consent to the
sublicensing by S&P to CME of the "TOPIX" trademark in connection with the creation, marketing, trading, clearing and promotion of S&P/TOPIX 150 Indexed Contracts under the terms of the Agreement. 

        In
addition, CME requests that Section 5(a) of the Agreement be amended to read as follows (additions are indicated by underlines): 

	5.
	LICENSE FEES.

        (a)  Basic
License Fee. Except as provided below, and subject to the terms and conditions of this Agreement, CME shall pay S&P ***** for each
trade of an Indexed Contract (except the S&P MidCap 400 for which the fee shall be ***** per trade), through October 21, 1997, and ***** per trade of an Indexed Contract after
October 21, 1997, and through and including the date on which this Agreement is terminated or expires pursuant to the terms hereof except for the S&P TOPIX 150 for which the fee
shall be as described below. 

        CME
shall pay S&P ***** fox each trade of a S&P/TOPIX 150 Indexed Contract at CME through and including the date on which this Agreement is terminated or expires pursuant
to the terms hereof unless during the term of this Agreement the ***** of traded S&P/TOPIX 150 Indexed Contracts exceeds *****. With respect to the ***** during which the ***** of traded S&P/TOPIX 150
Indexed
Contracts exceeds 5000 and for the *****, CME shall pay S&P ***** for each traded S&P/TOPIX 150 Indexed Contract, through and including the date on which this Agreement is terminated or expires
pursuant to the terms hereof. The initial multiple for the S&P/TOPIX 150 Index shall be *****, which is ***** times the current size of the S&P/TOPIX 150 Index traded on the Tokyo Stock Exchange. The
***** of S&P/TOPIX 150 Indexed Contracts shall be determined by *****. 

        For
the Indexed Contract base notwithstanding this amendment, all of the terms and conditions of the Agreement shall remain in full force and effect. 

        Please
acknowledge your receipt and acceptance of this amendment by signing below and returning this letter to us at your earliest convenience. If you have any questions or comments,

RECITALS:    
  

        WHEREAS on June 5, 1997, CME and EURONEXT (formerly SOCIETE DES BOURSES FRANCAISES) executed a certain
Central Services System (NSC) Software License and Development Agreement (the "Agreement") pursuant to which EURONEXT granted to CME a license, under certain conditions, to use the NSC System. 

        WHEREAS, pursuant to Section 2.1 (General Grant) of the Agreement, CME was granted a license, subject to certain conditions, to use
the NSC System for the trading only of CME listed products, the products of Approved Exchanges by Authorized Users, and U.S. denominated repurchase agreements involving non-European
sovereign debt obligations. 

        WHEREAS, pursuant to Section 2.2 (Restrictions on Use) of the Agreement, CME may not use the NSC System to provide services to any
third party. 

        WHEREAS, CME wishes to have the right (1) to use the NSC System to trade any type of products and (2) to use the NSC System
to provide ASP Services. 

        WHEREAS, the ownership of the NSC System was assigned by EURONEXT to Atos-Euronext SA, a French limited company incorporated
under the laws of France, with offices at Palais de la Bourse, 75002 Paris, and Atos-Euronext SA has authorized EURONEXT to grant CME such rights. 

        WHEREAS, EURONEXT is willing to grant CME such rights provided CME grants to EURONEXT the right under the Clearing 21®
Software License and Development Agreement dated June 5, 1997 between EURONEXT and CME (the "Clearing 21 Agreement") to use the Clearing 21 System (as defined in the Clearing 21 Agreement) to
provide certain ASP services to third parties. 

        WHEREAS, subject to the terms of an Amendment to the Clearing 21 Agreement dated the date hereof, CME has granted such rights to EURONEXT. 

        NOW THEREFORE, in consideration of the premises and the mutual promises and agreements herein expressed, the parties hereto agree as
follows:

	"ASP
Services" means the distribution by CME of Product trade matching services from CME's primary and back-up facilities to ASP Customers on a subscription basis using
the NSC System.

	(ee)
	"ASP
Transaction" means a matched trade between two parties (regardless of the size of the trade) which is matched by CME in the context of providing ASP Services to an ASP Customer.
For example, (a) a scenario where A sells 10 securities to B constitutes a single ASP Transaction and (b) a scenario where A sells 20 securities, B buys 5 of these securities and C buys
15 of these securities, constitutes two ASP Transactions.

	(ff)
	"NSC
System" means the Licensed Software (including the source and object codes) and the Licensed Materials as defined in the Agreement.

	(gg)
	"Products"
means, without limitation, futures, securities, options and other types of financial or commodity products. 

2.    Section 2.1. (General Grant) of the Agreement is hereby deleted and replaced with the following new Section 2.1:

(a) use the NSC System for the trading of: (i) CME listed Products, (ii) the Products of Approved Exchanges by Authorized Users, (iii) U.S. Dollar denominated repurchase
agreements involving non-European sovereign debt obligations, (iv) the Products of any ASP Customer, and (v) such other Products not covered by Subsections
(i)—(iv) above which CME and EURONEXT may mutually agree upon, in writing, subsequent to the Effective Date hereof; and (b) use the NSC System to provide ASP Services to any
ASP Customer, and (c) modify and enhance the Licensed Software. The uses permitted by Subsections (a), (b) and (c) above shall be at the locations selected from time to time by
CME and on the hardware configuration designated by CME. The licenses granted by EURONEXT to CME hereunder include the right to permit the operation of the NSC System by a wholly owned subsidiary of
Chicago Mercantile Exchange Holdings Inc. CME shall provide EURONEXT with written notice of the locations and hardware configuration designated by CME to operate the Licensed Software. If CME
chooses to operate the NSC System on a hardware configuration that has not been approved by EURONEXT, CME accepts sole responsibility for the results of such operation. 

2.    Section 2.2. (Restrictions on Use) of the Agreement is hereby deleted and replaced with the following new Section 2.2: 

CME
shall not use the NSC System: *****. The foregoing restrictions shall not apply to any Common Software incorporated into the Licensed Software for which CME has obtained a separate license. In the
event that CME incorporates any portion of the Licensed Software into other systems or programs owned or operated by CME, *****. 

3.    The following Section 4.8 is hereby added to the Agreement:

such audit results in a determination that there has been an underpayment greater than ***** of the payment actually made pursuant to the last ***** Statement, then the costs of the audit shall be
borne by CME. 

5.    Article 6 (Product Warranties) of the Agreement is hereby amended to include the following new paragraph: 

Nothing
in this Agreement shall be construed as a representation made or a warranty given by EURONEXT as to the ability of CME to provide ASP Services using the NSC System. 

6.    Section 7.1 (Defense of Claim against CME) of the Agreement is hereby renumbered as Section 7.1 (a). 

7.    Section 7.1 (Defense of Claim against CME) of the Agreement is hereby amended to include the following new Section 7.1

Notwithstanding
Section 7.1(a), EURONEXT shall not indemnify CME nor save it harmless from any and all costs, losses, damages, liability, claims and demands (collectively "Intellectual Property
