(a)

any actual or alleged breach of the representations, warranties and undertakings contained in, or made or deemed to be made by the Issuer under, this Agreement; or

6.3

In case any action shall be brought against any Relevant Party in respect of which recovery may be sought from the Issuer under this clause 6, the relevant Joint Lead Manager shall promptly notify the Issuer in writing but failure to do so will not relieve the Issuer from any liability under this Agreement.

6.4

The Issuer shall not, without the prior written consent of the Relevant Party, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim or action in respect of which recovery may be sought hereunder (whether or not any Relevant Party is an actual or potential party to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each Relevant Party from all liability arising out of such claim or action and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of a Relevant Party.

6.5	The Issuer shall not be liable to indemnify any Relevant Party where the relevant claim or action has been settled or compromised without prior consultation with the Issuer.

6.6

The Issuer undertakes with the Joint Lead Managers that it will forthwith notify the Joint Lead Managers of any change affecting any of the above representations and warranties (assuming and deeming them to have been repeated at the time of the change), and of any event which occurs as a result of which the Prospectus (as then amended or supplemented) would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the

statements therein, in the light of the circumstances under which they were made, not misleading, at any time before payment is made to the Issuer on the Closing Date and that it will take those steps which may be requested by the Joint Lead Managers to remedy and/or publicise the change or event (including, if requested, the publication of a supplement to the Prospectus). Upon any breach of any of the above representations and warranties or any change rendering any of the above representations and warranties inaccurate or any such event coming to the notice of the Joint Lead Managers before payment being made to the Issuer on the Closing Date, the Joint Lead Managers shall be entitled (but not bound) by notice to the Issuer to elect to treat such breach or change or event as (except as otherwise specifically provided) releasing and discharging the Joint Lead Managers from their obligations under this Agreement.

6.7

The above representations, warranties and indemnity shall continue in full force and effect in relation to each Joint Lead Manager notwithstanding its actual or constructive knowledge with respect to any of the matters referred to in the representations and warranties, the completion of the arrangements set out in this Agreement for the subscription and issue of the Notes or the termination of this Agreement pursuant to subclause 6.6, and clause 8 or 11.

7.	LISTING

7.1

The Issuer shall, if it has not already done so, make an application for the Notes to be listed on the Luxembourg Stock Exchange and admitted to trading on the Luxembourg Stock Exchange’s regulated market.

7.2	The Issuer confirms that the Prospectus has been approved as a prospectus by the CSSF.

7.3

If (after the approval of the Prospectus by the CSSF and before the commencement of trading in the Notes on the Luxembourg Stock Exchange’s regulated market) there arises or is noted a significant new factor, material mistake or inaccuracy relating to the information included in the Prospectus which is capable of affecting the assessment of the Notes, then the Issuer shall give to the Joint Lead Managers full information about the change or matter and shall produce and publish a supplementary prospectus (in a form approved by the Joint Lead Managers) in accordance with the Prospectus Directive.

7.4

If the Notes cease to be admitted to trading on the Luxembourg Stock Exchange’s regulated market the Issuer shall use all reasonable endeavours promptly to admit the Notes to trading on another European Economic Area regulated market (for the purposes of the Markets in Financial Instruments Directive (Directive 2004/39/EC)) to be agreed between the Issuer and Joint Lead Managers.

Accordingly, each Joint Lead Manager undertakes that it will not, directly or indirectly, offer or sell any Notes or have in its possession, distribute or publish any offering circular, prospectus, form of application, advertisement or other document or information in any country or jurisdiction except under circumstances that will, to the best of its knowledge and belief, result in compliance with any applicable laws and regulations and all offers and sales of Notes by it will be made on the same terms.

9.11	The representations, warranties and undertakings of each of the Joint Lead Managers under this clause 9 are several and not joint.

10.

STABILISATION

If a Joint Lead Manager (or persons acting on its behalf), in connection with the distribution of the Notes, offers Notes in excess of the aggregate principal amount to be issued or effects transactions with a view to supporting the market price of the Notes at levels other than those which might

otherwise prevail in the open market, such person(s) shall not in doing so be deemed to act as an agent of the Issuer. The Issuer will not as a result of any action taken by a Joint Lead Manager (or persons acting on its behalf), under this clause be obliged to issue Notes in excess of the aggregate amount of Notes to be issued under this Agreement, nor shall the Issuer be liable for any loss, or entitled to any profit, arising from any excess offers or stabilisation.

11.

TERMINATION

Notwithstanding anything contained in this Agreement, the Joint Lead Managers may by notice to the Issuer terminate this Agreement at any time before the time on the Closing Date when payment would otherwise be due under this Agreement to the Issuer in respect of the Notes if, in the opinion of the Joint Lead Managers, there shall have been such a change, whether or not foreseeable at the date of this Agreement, in national or international financial, political or economic conditions or currency exchange rates or exchange controls as would in their view be likely to prejudice materially the success of the offering and distribution of the Notes or dealings in the Notes in the secondary market and upon the notice being given the parties to this Agreement shall (except for the liability of the Issuer in relation to expenses as provided in clause 5 and except for any liability arising before or in relation to such termination) be released and discharged from their respective obligations under this Agreement.

12.

NO FIDUCIARY DUTIES

The Issuer acknowledges and agrees that each Joint Lead Manager is acting solely pursuant to a contractual relationship with the Issuer on an arm’s length basis with respect to the issue, offer and sale of the Notes (including in connection with determining the terms of the issue, offer and sale of the Notes) and not as a financial advisor or a fiduciary to the Issuer or any other person. Additionally, the Issuer acknowledges that the Joint Lead Managers are not advising the Issuer or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Issuer shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Joint Lead Managers shall have no responsibility or liability to the Issuer with respect thereto. The Issuer further acknowledges and agrees that any review by the Joint Lead Managers of the Issuer, the issue, offer and sale of the Notes, the terms of the Notes and other matters relating thereto will be performed solely for the benefit of the Joint Lead Managers and shall not be on behalf of the Issuer or any other person. The foregoing is without prejudice to any obligation of the Joint Lead Managers to make recommendations to the Issuer concerning the pricing and allocation of the offering in accordance with applicable rules of the UK Financial Services Authority.

AGREED FORMS OF AUDITORS’ COMFORT LETTERS

PART 1

[On the letterhead of PricewaterhouseCoopers LLP]

April 18, 2008

NYSE Euronext

and

ABN AMRO Bank N.V.

Barclays Bank PLC

Société Générale

X.X. Xxxxxx Securities Ltd.

Xxxxxx Xxxxxxx & Co. International plc

Ladies and Gentlemen:

We have audited:

1.	the consolidated financial statements of NYSE Euronext (the “Company”) and subsidiaries as of December 31, 2007 and 2006 and for each of the three years in the period ended December 31, 2007 and

2.	the effectiveness of the Company’s internal control over financial reporting as of December 31, 2007.

The consolidated financial statements referred to above are included in the preliminary prospectus dated April 8, 2008 and the prospectus dated April 18, 2008 related to the offering of the Company’s €750,000,000 5.375 per cent Notes due 2015. Our report, which contains an explanatory paragraph with respect to the Company’s exclusion of Euronext N.V. from our audit of the effectiveness of internal controls over financial reporting due to the fact that it was acquired by the Company in a purchase business combination during 2007, with respect to the audits referred to above is also included in the Prospectus. The preliminary prospectus dated April 8, 2008 and the prospectus dated April 18, 2008 are herein referred to as the “Prospectus”.

We are an independent registered public accounting firm with respect to the Company under Rule 101 of the Code of Professional Conduct of the Public Company Accounting Oversight Board (United States) (the “PCAOB”) and the applicable interpretations and rulings.

We have not audited any financial statements of the Company as of any date or for any period subsequent to December 31, 2007. Therefore, we are unable to and do not express any opinion on the Company’s financial position, results of operations or cash flows as of any date or for any period subsequent to December 31, 2007. Also, we have not audited the Company’s internal control over financial reporting as of any date subsequent to December 31, 2007. Therefore, we do not express any opinion on the Company’s internal control over financial reporting as of any date subsequent to December 31, 2007.

1.	At your request, we have read the minutes of the 2008 meetings of the stockholders, the Board of Directors, and the Audit Committee of the Company as set forth in the minute books at April 16, 2008, except for the minutes of the March 12, 2008 and March 27, 2008 Audit Committee meetings

and the March 13, 2008 Board of Directors meeting which were not approved in final form, for which drafts have been provided to us; officials of the Company having represented that such drafts include all substantive actions taken at such meetings, and have carried out other procedures to April 16, 2008 (our work did not extend to the period from April 17, 2008 to April 18, 2008, inclusive) as follows:

Company officials have advised us that no consolidated financial data as of any date or for any period subsequent to December 31, 2007 are available; accordingly, the procedures carried out by us with respect to changes in financial statement items after December 31, 2007 have, of necessity, been limited. We have inquired of certain officials of the Company who have responsibility for financial and accounting matters as to whether (a) at April 16, 2008 there was any change in the capital stock, increase in long-term debt, or decrease in consolidated stockholders’ equity of the Company as compared with amounts shown in the December 31, 2007 consolidated balance sheet included in the Prospectus; or (b) for the period from January 1, 2008 to April 16, 2008 there were any decreases, as compared with the corresponding period in the preceding year, in consolidated total revenues or in the total or per-share amounts of net income.

Those officials referred to above stated that (1) at April 16, 2008, there was no change in the capital stock, increase in long-term debt, or decrease in consolidated stockholders’ equity of the Company as compared with amounts shown in the December 31, 2007 consolidated balance sheet included in the Prospectus, and (2) there were no decreases for the period from January 1, 2008 to April 16, 2008, as compared with the corresponding period in the preceding year, in consolidated total revenues or in the total or per-share amounts of net income.

At your request, we have read the items identified by you on the attached copies of pages from the Prospectus and have performed the following procedures which were applied as indicated with respect to the letters explained below. We make no comment as to whether the U.S. Securities and Exchange Commission would view any non-GAAP financial information included in the Prospectus as being compliant with the requirements of Regulation G or Item 10 of Regulation S-K.

Compared with or recalculated from corresponding amounts included in the Company’s accounting records, giving effect to rounding where applicable, and found such amounts to be in agreement.

Compared with or recalculated from corresponding amounts included in the Company’s audited financial statements included in its annual report on Form 10-K for the year ended December 31 2007, giving effect to rounding where applicable, and found such amounts to be in agreement.

Compared and agreed to audited financial statements not included in the Prospectus.

Compared with or recalculated from corresponding amounts included in the Company’s accounting records, giving effect to rounding where applicable, and found such amounts to be in agreement. It should be noted that “net indebtedness” and “liquid funds” are not measures of operating performance or liquidity defined by generally accepted accounting principles and may not be comparable to similarly titled measures presented by other companies. We make no comment about the Company’s definition, calculation or presentation of “net indebtedness” and “liquid funds” or their usefulness for any purposes.

3.	Our audits of the consolidated financial statements for the periods referred to in the introductory paragraph of this letter comprised audit tests and procedures deemed necessary for the purpose of expressing an opinion on such financial statements taken as a whole. For none of the periods

referred to therein, nor for any other period, did we perform audit tests for the purpose of expressing an opinion on individual balances of accounts or summaries of selected transactions such as those identified by you, and, accordingly, we express no opinion thereon.

It should be understood that we have no responsibility for establishing (and did not establish) the scope and nature of the procedures enumerated in paragraphs 1 through 3 above; rather, the procedures enumerated therein are those the Managers asked us to perform. Accordingly, we make no representations regarding questions of legal interpretation or regarding the sufficiency for your purposes of the procedures enumerated in the preceding paragraphs; also, such procedures would not necessarily reveal any material misstatement of the amounts or percentages identified by you as set forth in the Prospectus. Further, we have addressed ourselves solely to the foregoing data and make no representations regarding the adequacy of disclosures or whether any material facts have been omitted. This letter relates only to the financial statement items specified above and does not extend to any financial statement of the Company taken as a whole.

5.	These procedures should not be taken to supplant any additional inquiries or procedures that you would undertake in your consideration of the proposed offering.

This letter is solely for your information and to assist you in your inquiries in connection with the offering of the securities covered by the Prospectus, and it is not to be used, circulated, quoted, or otherwise referred to for any other purpose, including but not limited to the registration, purchase, or sale of securities, nor is it to be filed with or referred to in whole or in part in the Prospectus or any other document, except that reference may be made to it in any list of closing documents pertaining to the offering of the securities covered by the Prospectus.

7.	We have no responsibility to update this letter for events and circumstances occurring after April 16, 2008

Very truly yours,
