NEW YORK and ATLANTA, April 26, 2011 - NASDAQ OMX (NDAQ) and IntercontinentalExchange (ICE) today issued the
following open letter to NYSE Euronext stockholders. NASDAQ OMX and ICE also
filed an investor presentation that highlights the strategically and
financially superior nature of the NASDAQ OMX/ICE proposal when compared to
the existing Deutsche Boerse proposal.

Dear NYSE Euronext Stockholder:

NYSE Euronext's management and Board continue to deny that the NASDAQ
OMX/ICE proposal is superior to the existing Deutsche Boerse agreement or
that they have a fiduciary duty to review the proposal. Simply put, your
Board is ignoring corporate governance best practices and the market reality
of the situation.

    - Our proposal offers substantially greater short and long-term value and
      creates a compelling opportunity for the NYSE Euronext Board to meet
      with us while presenting no downside risk and only upside for
      stockholders - the Deutsche Boerse agreement allows for discussions in
      the event the NYSE Euronext receives a proposal that may possibly be
      superior.
    - We have offered mutual due diligence, and appropriate safeguards so
      that no competitive risks are posed to NYSE Euronext.
    - Our reverse break-up fee is a significant improvement on the Deutsche
      Boerse agreement and alongside committed financing, with no conditions,
      addresses the key concerns of the NYSE Board.
    - We have presented a fair and balanced form of Merger Agreement, based
      largely on the existing Deutsche Boerse agreement, and we are open to
      negotiating this form of agreement to address any legitimate concerns
      of the NYSE Euronext Board.
    - The Hart-Scott-Rodino anti-trust review is well underway and NASDAQ OMX
      has received and is responding to a Second Request for information in
      connection with NASDAQ OMX's filing.
    - The discovery that the initial synergies provided by NYSE
      Euronext/Deutsche Boerse were understated by one-third after two years
      of exploratory discussions should be carefully considered against the
      history of NYSE Euronext and Deutsche Boerse failing to deliver
      promised synergy estimates in their past transactions.
    - The strategy that NASDAQ OMX and ICE have laid out is highly attractive
      and complementary to the NYSE's strategy of international expansion and
      increased operating efficiencies.

NASDAQ OMX and ICE encourage NYSE Euronext's stockholders to call on
their Directors to meet with us to address any concerns they have and start a
mutual due diligence process. Taking this small step would create no
commitment and would reassure NYSE Euronext's stockholders that a thorough
review process has been undertaken.

As NYSE Euronext stockholders, which would you choose - engagement on a
financially superior proposal, or a story about why an inferior transaction
is really "superior"?

The NYSE should live up to the principles that they espouse for the
stockholders of the companies listed on the New York Stock Exchange. Ask your
Board to reconsider their refusal to engage on our superior proposal.

Sincerely,

Robert Greifeld, Chief Executive Officer & President, The NASDAQ OMX
Group, Inc

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