General

4.1.1 The Atos Origin Group will be the Preferred Supplier (as defined in Article 5 below) of the NYSE Euronext Group for clearing and settlement IT Services for a period of three (3) years following the Closing. For example, if NYSE Euronext acquires a vertically integrated exchange and the clearing system of such exchange needs to be updated or replaced, the Atos Origin Group will be the Preferred Supplier.

4.1.2 NYSE Euronext will be free to develop or change its own clearing and settlement capabilities or systems in-house as it sees fit for all its businesses. However, if NYSE Euronext or any member of the NYSE Euronext Group intends to outsource the maintenance, the support or the run of such IT Services to an external provider, the Atos Origin Group will be the Preferred Supplier.

4.1.3 With respect to the international sales to third parties for the front to back solution (i.e., including trading and clearing solutions), if a member of the NYSE Euronext Group intends to license its trading system, the Atos Origin Group will be the Preferred Supplier of the clearing and settlement IT Services (if such IT Services are requested by the customer and so long as the Atos Origin Group solution meets the requirements of the customer). The IT Services delivered by the Atos Origin Group will be based on the C21 IPR or any new product developed by the Atos Origin Group.

7

TRS/CPS

4.1.4 Atos Origin acknowledges that none of the contracts relating to TRS/CPS shall be transferred from AEMS LTD to AW on the Closing. Accordingly, NYSE Euronext acknowledges and agrees that AEMS (or any of its Affiliates) shall purchase from AW a UCS license for an amount of EUR [        ]* million, which shall be paid on the Closing Date.

4.1.5 NYSE Euronext shall be free to develop TRS/CPS as it sees fit for its own group purposes. However, NYSE Euronext shall not market TRS/CPS to third parties (other than LCH Clearnet and ICE) as a standalone solution, but only in connection with other IT Services. If a member of the NYSE Euronext Group intends to provide a third party with a derivative clearing and settlement solution, the Atos Origin Group will be the Preferred Supplier of such IT Services, save in the event the NYSE Euronext Group enters into a Strategic Partnership with such third party. For the purposes of this Article 4.1.5, “Strategic Partnership” shall mean an arrangement with a third party pursuant to which (i) NYSE Euronext acquires at least 5% of the share capital and voting rights of such third party, and (ii) such third party operates or will operate a trading platform provided by NYSE Euronext.

C21

4.1.6 As soon as possible after the date hereof and in any event before Closing, NYSE Euronext shall cause Euronext Paris to transfer to AW the C21 IPR in accordance with the terms and conditions of a transfer agreement substantially in the form attached as Exhibit E (the “C21 Transfer Agreement”).

4.1.7 NYSE Euronext shall cause the sublicense contract between Euronext Paris and LCH Clearnet SA dated January 30, 2001 (the “2001 Sublicense”) to be transferred to AW.

4.1.8 NYSE Euronext shall cause the sublicense contract between Euronext Paris and LCH.Clearnet Limited dated December 22, 2003 (the “2003 Sublicense”, together with the 2001 Sublicense, the “LCH Sublicenses”) to be transferred to AW.

4.1.9 From the date of such transfers, AW will charge LCH Clearnet SA and LCH.Clearnet Limited a fee that shall not exceed the fee currently charged by NYSE Euronext under the LCH Sublicenses, i.e. EUR [        ]* million for LCH Clearnet SA and EUR 0 for LCH.Clearnet Limited, it being understood that (i) LCH.Clearnet Limited has to date not used any of the services provided for under the 2003 Sublicense and (ii) if LCH.Clearnet Limited were to use such services in the future, AW will charge fees for such services in accordance with the terms of the 2003 Sublicense.

4.1.10 From the effective date of the transfer of the C21 IPR until December 31, 2009, Atos Origin will provide to NYSE Euronext, semi-annually, a report listing the markets that use clearing services based on C21 and the prospects of additional markets that may use clearing services based on C21.

4.2 Aramis Operations

As from Closing, all costs related to the development and operation of Aramis (as set out in schedule 2 to the Aramis License and Services Agreement) shall be invoiced by AEMS Belgium to NYSE Euronext for so long as Aramis is used by it (directly or through its clients), it being understood that NYSE Euronext shall be free to cease using Aramis at any time without any early termination cost or other penalty, subject to three (3) months’ prior notice. The License Agreement for Aramis shall be substantially in the form attached as Exhibit F (the “Aramis License and Services Agreement”).

- AEMS LTD has to date paid to Oracle license fees in an amount of £3,000,000 covering the purchase of the licenses; and

- maintenance fees are paid to Oracle on a yearly basis (i.e., £740,000 from May 2007 to April 2008 and £755,000 from May 2008 to April 2009).

4.3.2 In light of the foregoing, NYSE Euronext shall use its best efforts to provide Atos Origin, not later than the Closing Date, with written confirmation from Oracle that (i) as from Closing, the benefit of the Oracle License shall be transferred (at no cost) to AI 16 (as far as the Transferred Businesses are concerned, and with the right to sublicense within the group) (ii) AEMS Belgium, Diamis and AI 16 shall continue to benefit from the Oracle License after the Closing (at no cost), and (iii) AEMS Belgium, Diamis and AI 16 will not pay any additional maintenance fees for the period comprised between the Closing and April 2009 with respect to licenses already deployed as at the Closing date.

4.4 Guarantees

As from Closing, NYSE Euronext (or Euronext) shall be substituted for Atos Origin with respect to the parental guarantees listed in Schedule 5 attached hereto, and Atos Origin shall be released from any and all obligations in relation to such parental guarantees. NYSE Euronext hereby undertakes to fully indemnify and hold harmless Atos Origin from and against any and all Losses suffered or incurred by Atos Origin and/or its Affiliates, directors, officers and employees, and/or the directors, officers and employees of such Affiliates, after the Closing in relation to such parental guarantees, to the extent that such Losses result from facts or circumstances the origin of which is subsequent to the Closing Date.

4.5 Haussmann Lease

4.5.1 The Parties hereby agree that the current lease dated April 20, 2001 (as amended on June 6, 2002 and June 6, 2008) between AEMS France and Société Immobilière Privat for the premises located at 6/8 Boulevard Haussmann in Paris (the “Haussmann Lease”) shall remain with AEMS France.

9

4.5.2 As from the Closing, Atos Origin shall:

(a) sub-lease from AEMS France 50% of the total surface area of the Haussmann Lease premises (taking into account the “mètres carrés utiles”), for a rental price per square meter equal to 75% of the Total Housing Cost per square meter (excluding VAT); and

(b) have the option to sub-lease all or part of the remaining 50% of the total surface area (if such surface area is unoccupied and available for lease) for a rental price per square meter equal to 50% of the Total Housing Cost per square meter (excluding VAT).

For the purposes of this Article, the “Total Housing Cost” shall be the actual rental cost (including maintenance costs and all other charges, as described in Schedule 6) under the Haussmann Lease.

4.5.3 The Parties shall cause AEMS France to use its best efforts to obtain, as soon as possible and in any event no later than the Closing, the consent of the landlord of the Haussmann Lease to the sublease referred to in Article 4.5.2, it being specified that such consent should not be subject to any amendments to the current terms and conditions of the Haussmann Lease. Subject to the obtaining of the above consent, Atos Origin and AEMS France shall on the Closing Date enter into a sublease agreement in the form attached as Exhibit G (the “Haussmann Sublease”).

4.5.4 The Parties hereby agree that the provisions of the Haussmann Sublease shall be given retroactive effect as from the date hereof, irrespective of the date of the Closing and of the consent referred to in Article 4.5.3 above. Accordingly, NYSE Euronext shall pay to Atos Origin on Closing a sum corresponding to the result of the following formula, it being understood that such formula shall be applied on a monthly basis for the period from the date hereof until Closing so as to take into account the monthly variations of the surface occupied by Atos Origin (the “Haussmann Payment”):

(	THC	x 37.5%) + [(SOAO x	THC	) x 50%] x NM
	12		12

Where:

“THC” means “Total Housing Cost”;

“SOAO” means the surface occupied by Atos Origin out of the remaining 50% of the total surface area referred to in Article 4.5.2(b) above; and

“NM” means the number of months elapsed from the date hereof until Closing, it being understood that for any period of less than one month, the result shall be adjusted prorata temporis.

For the avoidance of doubt, the Haussmann Payment shall be the total sum of the monthly calculated amounts for the period from the date hereof until Closing.

* We have requested that the omitted information be accorded confidential treatment and have filed such information separately with the SEC.

10

4.6.2 Should LCH.Clearnet replace the network covered by such contract with a new network provided by NYSE Euronext, NYSE Euronext hereby undertakes to provide network services in relation thereto at market rates, in order to facilitate back-to-back arrangements on mutually acceptable terms between NYSE Euronext, Atos Origin and LCH.Clearnet.

The Hosting Amendment shall give effect to the Transaction as a whole and its effect on the scope of services provided under the hosting services agreement, and shall relate principally to the following aspects: term (until December 31, 2010, with renewal and notice periods to be decided), termination rights and consequences, and fees.

4.9 Transition Services

4.9.1 As from the Closing, the Atos Origin Group shall provide the AEMS Group, and NYSE Euronext shall cause the AEMS Group to provide entities of the Atos Origin Group, with certain interim support services (and notably, finance, legal, HR and procurement matters) and operational services as currently provided and at current costs, including inter alia the use of certain intellectual property rights to the extent that such intellectual property rights are used for the sole purposes of the support services rendered). The main terms and conditions of the transition services are set out in Exhibit H (the “Transition Services”).

Where required, and to the extent not otherwise contemplated in this Agreement or the Ancillary Agreements, the Atos Origin Group will give the AEMS Group, and NYSE Euronext shall cause the AEMS Group to give the entities of the Atos Origin Group, as from Closing, a non-exclusive right to use and to sub-license within their respective groups and to customers, the intellectual property rights owned by each of them that are strictly necessary to carry out their respective businesses, as such businesses were conducted in the ordinary course by the AEMS Group through the date hereof, and consistent with past practice within the AEMS Group (i.e., for the avoidance of doubt, the businesses covered by the preceding sentence with respect to Atos Origin are limited to Transferred Businesses). Unless otherwise agreed in good faith between the Parties, the rights granted under this Article 4.11 will be at no cost. If in view of the nature and/or scope of the rights granted under this Article 4.11, the Parties, acting in good faith, agree that a consideration should be paid by the party benefiting from the license, such consideration will be in line with market price. This license shall include the right to create improvements and derivative works, and the right to use such improvements and derivative works, with ownership of such improvements and derivative works to belong to the beneficiary of the license, with a royalty-free right to use for the other party. The licenses referred to above shall be granted for a duration equal to the duration of the protection of the intellectual property rights. The party who has granted a license undertakes to use its reasonable endeavors to maintain the licensed intellectual property rights in force.

ARTICLE 5 - PREFERRED SUPPLIER

5.1 For a period of three (3) years following the Closing, Atos Origin Group shall be the Preferred Supplier of the NYSE Euronext Group for IT Services.
