NASDAQ OMX Group and IntercontinentalExchange Deliver Proposed Merger Agreement to NYSE Euronext Board of Directors;

Demonstrate Commitment to Proposal that is Superior by 21% or $2 Billion

NEW YORK and ATLANTA, April 19, 2011 - NASDAQ OMX (NDAQ) and IntercontinentalExchange (ICE) today announced they
have taken a series of steps demonstrating their commitment to pursuing their
superior proposal with NYSE Euronext and providing greater certainty to the
NYSE Euronext Board.

(Logo: photos.prnewswire.com/prnh/20090727/CL51999LOGO )

    -- A proposed merger agreement has been submitted to the NYSE Euronext
       Board that is consistent with the terms of the current business
       Combination agreement with Deutsche Boerse;
    -- NASDAQ OMX and ICE are prepared to pay a reverse termination fee of
       $350 million (USD), in the event that they are unable to obtain
       necessary antitrust and competition approvals;
    -- NASDAQ OMX and ICE have received fully committed financing of $3.8
       billion from a group of leading institutions; and
    -- Actions necessary to start the U.S. antitrust review processes have
       been taken and those reviews are expected to commence shortly.

A copy of the letter that accompanied the proposed merger agreement sent
to the NYSE Euronext Chairman today is attached to this press release.

Robert Greifeld, Chief Executive Officer of NASDAQ OMX, said, "Our
actions today demonstrate our commitment to pursuing this transaction and
further illustrate exactly how our proposal is superior. This should also
eliminate any concerns that the NYSE Euronext Board has about engaging in
discussions with us. It's time to allow a reasonable and expeditious
diligence process to begin."

Jeffrey C. Sprecher, Chairman and Chief Executive Officer of ICE, said,
"Based on the feedback we have heard from NYSE Euronext stockholders, we are
more confident than ever that the proposed NASDAQ OMX/ICE transaction is
better for them, the markets and the exchange's customers. We trust that the
NYSE Euronext Board will seek to enhance the value to its stockholders by
meeting with us to evaluate our superior proposal."

Superior Proposal

The NASDAQ OMX/ICE proposal remains superior by a significant and
inescapable margin. Based on April 18th closing prices, the NASDAQ OMX/ICE
proposal outlined in the proposed merger agreement is valued at $42.67 per
NYX share. This is 21%, or $2 billion, above the $35.29 value per NYX share
under the Deutsche Boerse transaction. Under the NASDAQ OMX/ICE proposal, the
combined company would incorporate the iconic NYSE name and floor and
strengthen investor confidence in U.S. equity markets, which have been shaken
by fragmentation. In addition, NYSE Euronext stockholders will benefit from
the transaction's cash component as well as a meaningful participation in a
newly combined ICE/Liffe derivatives business that will preserve competition
in the European Union.

$350 Million Reverse Break-Up Fee Demonstrates Confidence in Ability to
Receive Necessary Competition Approvals

The addition of the $350 million reverse break-up fee in the proposed
merger agreement, which NYSE Euronext would receive in the event of a failure
to obtain required antitrust or competition approvals, demonstrates how
convinced we are that we will obtain all necessary regulatory approvals.
These significant improvements to the Deutsche Boerse proposal address any
legitimate concerns of the NYSE Euronext Board with respect to the execution
risk of the NASDAQ OMX/ICE proposal as compared to the execution risk of the
Deutsche Boerse proposal, particularly in light of the substantial overlap in
the Deutsche Boerse and NYSE Euronext European derivatives businesses that
may create execution and timing risk in the Deutsche Boerse deal. In short,
our addition of a reverse break-up fee demonstrates our confidence.

Committed Financing of $3.8 Billion

As previously announced, NASDAQ OMX and ICE would finance the cash
portion of the acquisition purchase price through cash on hand and a combined
$3.8 billion financing commitment. NASDAQ OMX has signed and received a fully
committed financing from a syndicate of banks including Bank of America,
Nordea Bank AB (publ), Skandinaviska Enskilda Banken AB (publ) and UBS
Investment Bank. ICE has signed and received fully committed financing from a
syndicate of banks including Wells Fargo and Bank of America. NASDAQ OMX and
ICE remain committed to a prudent use of leverage to finance the transaction.
In particular, NASDAQ OMX is focused on maintaining its investment-grade
credit rating.

Letter Sent to NYSE Euronext Chairman

    April 19, 2011
    Board of Directors
    Attn: Jan-Michiel Hessels - Chairman of the Board of Directors
    NYSE Euronext
    11 Wall Street
    New York, NY 10005

Dear Mr. Hessels:

We believe the joint proposal of The NASDAQ OMX Group, Inc. ("NASDAQ
OMX") and IntercontinentalExchange, Inc. ("ICE") to combine with NYSE
Euronext offers terms that are substantially more favorable to your
stockholders than the terms of your agreement with Deutsche Boerse. As such,
we were extremely disappointed to see the announcement that the Board of
Directors of NYSE Euronext (the "Board") determined to summarily reject our
proposal without any discussion with us. Since making public our proposal to
combine with NYSE Euronext, we have had the opportunity to discuss our
transaction with industry participants and your stockholders. Our already
strong resolve to complete a combination of the companies has been reinforced
by these discussions.

While we regret the Board's decision to reject our proposal, we have paid
careful attention to the reasons you have articulated in support of that
decision in order to respond to the legitimate concerns of the Board. Most
importantly, however, we take issue with the Board's statements that the
proposed acquisition of NYSE Euronext by Deutsche Boerse is strategically
more attractive than our proposal. We cannot imagine a more strategically
powerful opportunity for NYSE Euronext stockholders than to be able to
participate in two highly focused companies, one focused on the cash equities
business and the other focused on derivatives, rather than the exchange
supermarket proposed to be created by Deutsche Boerse. We believe that your
stockholders should be given the opportunity to make the decision as to how
best to allocate their interests in NYSE Euronext. We believe that, in
addition to a superior financial proposal, the synergies available for our
customers, our ability to lower costs and the highly focused business
segments of NASDAQ OMX and ICE are significantly more attractive in both the
short-term and the long-term than the proposed acquisition of NYSE Euronext
by Deutsche Boerse.

In order to further progress our proposal, we have attached to this
letter a proposed form of Agreement and Plan of Merger (the "Merger
Agreement") detailing the transaction proposal previously communicated to you
in our letter of April 1, 2011. Subject to confirmatory due diligence, we
would be willing to enter expeditiously into a definitive agreement
substantially in the form attached. Toward this end and in light of our
superior offer, we anticipate the Board's decision to meet with us and allow
us to conduct due diligence with the objective of negotiating the final
merger agreement. In doing so, we are confident that we will be able to
address any questions the Board may have regarding our superior proposal.

In addition to providing you with the proposed form of Merger Agreement,
we are pleased to inform you that each of us has received fully executed
commitment letters from our respective lenders in order to fully finance the
cash portion of our offer, and, as you will see in the proposed form of
Merger Agreement, our proposed transaction is not subject to any financing
condition. We are prepared to share the commitment letters with you at such
time as we execute an appropriate and customary confidentiality agreement.

We have reflected in the attached Merger Agreement our willingness to
accept substantially all of the terms of your existing Business Combination
Agreement with Deutsche Boerse, and we remain highly confident in our ability
to obtain all regulatory approvals in connection with our proposed
transaction. To this end, we have provided for a "reverse break-up fee" of
$350 million in the attached Merger Agreement to eliminate any concerns you
might have regarding our ability to obtain regulatory approval for our
transaction. In short, we believe that the transaction that NASDAQ OMX and
ICE have proposed is financially and strategically superior to your proposed
transaction with Deutsche Boerse, and that our proposed transaction is
concrete and executable as evidenced by our willingness to enter into the
attached Merger Agreement and offer the reverse break-up fee. This commitment
is backed by the financial resources of our respective companies and is fully
supported by each of our Boards of Directors.

The agreement with Deutsche Boerse permits you to engage in discussions
with us and allow us to undertake our due diligence investigation of NYSE
Euronext if you believe that "there is a reasonable likelihood that our
proposal could constitute a Superior Proposal." In this regard, you need not
actually determine that our proposal is, at this time, a Superior Proposal.
There is no question that our proposal is economically "Superior", indeed far
superior, and we believe your duty to be well informed requires that you
discuss with us any issues that could conceivably overcome this sharp
difference in the value of the two offers. By engaging with us, you will be
enhancing your ability, and the ability of your stockholders, to consider our
proposal, and you will also discover whether Deutsche Boerse would improve
its offer in response. Your stockholders have an obvious interest in
understanding the benefits accruing to them under our proposal as well as its
strategic rationale and its likelihood of completion. Based on our own
conversations with your stockholders, we sense that they want the Board to
engage with us to determine if, in fact, our proposal is better for NYSE
Euronext, its stockholders, and the broader markets.

In preparing this Agreement, we have gone to great lengths to stay within
the boundaries of your pending agreement with Deutsche Boerse, so as not to
impose upon NYSE Euronext burdens or obligations not imposed by Deutsche
Boerse, and we have added a key benefit (in addition to our substantially
higher price) that you did not obtain in your negotiations with Deutsche
Boerse. More specifically:

    -- We have not asked that you make any material representation
       or warranty that you have not already provided to Deutsche Boerse;
    -- We have not asked that you agree to any covenant with respect to
       the operations of your business during the pendency of the transaction
       that you have not already agreed to with Deutsche Boerse;
    -- We have eliminated the burdensome "force the vote" obligation
       that you agreed to in your agreement with Deutsche Boerse; and
    -- We have added a $350 million reverse break-up fee to be payable
       by us to you in the event that we are unable to close the transaction
       as a result of a failure to obtain anti-trust or competition
       approvals.

We view the addition of the reverse break fee in the event we fail to
obtain anti-trust or competition law approvals as being a significant
improvement to your proposed Deutsche Boerse transaction, as well as
demonstrating our confidence that we can address any anti-trust or
competition issues that may be raised. As you know, Deutsche Boerse has not
expressed a similar level of confidence as it is not obligated to pay any fee
to NYSE Euronext if its transaction is blocked by regulators. While we are
sure that you have analyzed the competition issues involved in that
transaction, based on our preliminary analysis, we are of the view that your
proposed Deutsche Boerse transaction (i) will take longer to review in the
European Union than ours will take to review in the United States, and (ii)
as has been publicly acknowledged by NYSE Euronext(1) faces significant
challenges before the European Union competition authorities. If the
regulators require actions that would impose a 'substantial detriment' on
Deutsche Boerse, Deutsche Boerse will have the option to close or not close
their transaction as they see fit, and they will not be obligated to pay a
break-up fee to you or your stockholders if they decide not to close. This is
on top of the deal risk posed by the requirement in the Deutsche Boerse
transaction that the holders of 75% of Deutsche Boerse's shares tender into
the offer contemplated by the Business Combination Agreement.

NASDAQ OMX and ICE are currently engaged in discussions with the Staff of
the Antitrust Division of the Department of Justice concerning its review of
our proposed transaction and, as part of those discussions, NASDAQ OMX and
ICE are responding to staff requests, and providing to the staff information
and documents concerning NASDAQ OMX's and ICE's businesses and the market
environment in which they operate. In addition, we intend to acquire shares
of common stock of NYSE Euronext and, as a result of these acquisitions,
intend to hold voting securities of NYSE Euronext valued in excess of $66
million. We will file notification of this intent under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 (the "HSR Act") with both the Federal
Trade Commission and Antitrust Division of the Department of Justice,
triggering the formal commencement of the waiting period under the HSR Act.

As we described in our letter of April 1, 2011, if the Board were to
engage in dialogue with us, we also believe that our proposal could be
structured as a tax-free transaction to the NYSE Euronext stockholders with
respect to the stock consideration to be issued in the transaction. In order
to assist the Board in its understanding of the proposed structure, we would
be pleased to provide the Board and its advisors with a summary of the
detailed steps and revisions that would be made to the draft Merger Agreement
to effect a tax efficient separation of the businesses and their respective
tax free combinations with NASDAQ OMX and ICE. We look forward to discussing
with you how to make this benefit of our transaction available to the NYSE
Euronext stockholders. Also, because a significant portion of the
consideration that we are offering in our proposal consists of stock in
NASDAQ OMX and ICE, we are both ready to make available to NYSE Euronext and
its advisors the materials they will need to conduct appropriate diligence on
our respective companies.

This letter and the enclosed Merger Agreement are intended to be an
indication of the seriousness of our interest to enter into a transaction
with NYSE Euronext on the terms and conditions proposed in the attached form
of Merger Agreement - including our provision of a reverse break-up fee -
subject to a focused and expeditious due diligence review. Although NASDAQ
OMX, ICE and NYSE Euronext will be bound only in accordance with terms and
conditions to be negotiated and contained in a definitive agreement among the
parties, both NASDAQ OMX and ICE are deeply committed to achieving a
transaction. We intend to issue a press release to publicly disclose this
letter.

Given the details provided on our superior offer, we await the Board's
decision to meet with us and allow us to conduct due diligence with the
objective of negotiating the final merger agreement. In doing so, we are
confident that we will be able to address any questions of the Board
regarding our proposal. With your cooperation, we are confident we could
negotiate and sign a definitive merger agreement rapidly. Thank you for your
consideration and we look forward to hearing from you as soon as feasible.

    Very truly yours,

    Robert Greifeld
    Chief Executive Officer
    The NASDAQ OMX Group, Inc.

    Jeffrey C. Sprecher
    Chairman & Chief Executive Officer
    IntercontinentalExchange, Inc.

side it's obvious that if you look at what the envisioned NewCo would be, we
have a lot of work to do with the competition authorities in Brussels, to
talk about the derivatives market and OTC derivatives market." CNBC interview
of CEO of NYSE Euronext, Duncan Niederauer, April 11, 2011.
