In connection with the proposed business combination transaction between NYSE Euronext and Deutsche Boerse AG, Alpha Beta Netherlands Holding N.V. (“Holding”), a newly formed holding
company, has filed, and the SEC has declared effective on May 3, 2011, a Registration Statement on Form F-4 with the U.S. Securities and Exchange Commission (“SEC”) that includes (1) a
proxy statement of NYSE Euronext that will also constitute a prospectus for Holding and (2) an offering prospectus of Holding to be used in connection with Holding’s offer to acquire Deutsche
Boerse AG shares held by U.S. holders. Holding has also filed an offer document with the German Federal Financial Supervisory Authority (Bundesanstalt fuer Finanzdienstleistungsaufsicht)
(“BaFin”), which was approved by the BaFin for publication pursuant to the German Takeover Act (Wertpapiererwerbs-und Übernahmegesetz), and was published on May 4, 2011. 
Investors and security holders are urged to read the definitive proxy statement/prospectus, the offering prospectus and the offer document regarding the proposed business combination
transaction because they contain important information. You may obtain a free copy of the definitive proxy statement/prospectus, the offering prospectus and other related documents filed by
NYSE Euronext and Holding with the SEC on the SEC’s Web site at www.sec.gov. The definitive proxy statement/prospectus and other documents relating thereto may also be obtained for free
by accessing NYSE Euronext’s Web site at www.nyse.com. The offer document is available at Holding’s Web site at www.global-exchange-operator.com. 
This document is neither an offer to purchase nor a solicitation of an offer to sell shares of Holding, Deutsche Boerse AG or NYSE Euronext. The final terms and further provisions regarding the
public offer are disclosed in the offer document that has been approved by the BaFin and in documents that have been filed with the SEC. 
No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the U.S. Securities Act of 1933, as amended, and applicable European
regulations. Subject to certain exceptions to be approved by the relevant regulators or certain facts to be ascertained, the public offer is not being made directly or indirectly in or into any
jurisdiction where to do so would constitute a violation of the laws of such jurisdiction, or by use of the mails or by any means or instrumentality (including without limitation, facsimile transmission,
telephone and the internet) of interstate or foreign commerce, or any facility of a national securities exchange, of any such jurisdiction. 
This announcement and related materials do not constitute in France an offer for ordinary shares in Holding. The relevant final terms of the proposed business combination transaction will be
disclosed in the information documents reviewed by the competent European market authorities.

Client Cost Savings from the Proposed NYX/DB Merger
11
Primary Benefits
Eliminate redundant market connectivity
Customers
can
eliminate
non-SFTI
point-to-point
carrier
circuits.
Assuming
that
customers
have
the
necessary bandwidth, they can use SFTI to access 30+ destinations
On
average,
we
estimate,
savings
could
be
anywhere
from
$1,500/month
(low
speed)
to
upwards
of
$15,000/month
(10
GB)
for
two
connections
per
customer
Leverage existing Mahwah co-lo services
Customers can use their existing co-lo infrastructure (hardware + network)
We
anticipate
that
an
average
client
savings
could
be
in
the
range
of
$4,000
-
$7,000/month
Decreased development expenditure if ISE is migrated to UTP
Cost
efficiencies
will
allow
clients
to
repurpose
broker
support
staff
and
resources
to
core
business
projects
Other Benefits
Simpler client interface
Once groups are integrated, clients will benefit from a more harmonized customer experience on several
levels
Relationship management => savings in Exchange relationship teams
Single communication process
Real time support (market surveillance and technical help desk) => one number to call instead of two
ISE clients that are not currently on SFTI can gain access to our wide range of products/services

Technology
12
Single technical connection for all markets
Single co-location set up

More harmonized customer experience (single communication process for support and relationship
management)


Clearing
13
One clearing house and clearing system: Eurex clearing
Eliminate duplicating clearing infrastructure
Eliminate duplicating direct memberships of CCPs
Operational efficiencies
Single clearing interface, standardized business practices and policies/procedures eliminate
risk/complexity, and reduce direct and indirect cost
Common, consistent service model to improve customer experience
More efficient capital management
Reduce the need to move capital among multiple Clearing Houses
Achieve netting effects and capital efficiencies through structured products
Customer margin savings
Customer default fund savings towards Clearing Houses
Migration path
To be determined, but will be designed to minimize impact and cost on customers
