Equiduct Partners With Knight

Expanding the Platform's Capabilities With Strategic Investment

JERSEY CITY, New Jersey and LONDON, June 8, 2010 - Knight Capital Group, Inc. (NYSE Euronext: KCG) and Equiduct Systems
Ltd., today announced that Knight has agreed to make a strategic investment
in Equiduct, the pan-European equities trading platform. Knight's Kee-Meng
Tan, Managing Director and Head of the Electronic Trading Group in Europe,
will join the Equiduct board. Terms of the investment, which remains subject
to approval by Equiduct's shareholders, were not disclosed.

"Knight is partnering with Equiduct and Citadel Securities to help level
the playing field for retail investors in Europe," Mr. Tan said. "Retail
investors have very few resources available to address challenges in the
marketplace - fragmentation in European markets, the absence of a
consolidated tape and limited price discovery. The Equiduct model, powered by
cutting-edge technology, gives broker-dealers the ability to provide
high-quality execution to their end clients at the best price."

"We welcome this important strategic investment by Knight, which
demonstrates our commitment to making Equiduct a leading European trading
platform," said Peter Randall, Chief Executive Officer of Equiduct. "Together
with Knight and Citadel Securities, we will enhance our fast, cost-effective,
all-in-one solution for retail broker-dealers."

Equiduct has created PartnerEx (BEST), an innovative market model that
aggregates pricing data and gives broker-dealers the ability to satisfy their
best execution pricing obligations for retail clients trading in equities.
Both Knight and Citadel Securities act as market makers on PartnerEx.
Equiduct also operates a traditional order book (BOOK) that includes
executable two way quotes for over 1,100 leading European names. Knight and
Citadel Securities are active participants in this segment.

Equiduct is majority owned by Citadel Securities. As part of the
transaction, Borse Berlin AG will maintain their current shareholding in
Equiduct and continue to provide the platform with regulated market
infrastructure and supervision.

"We are very pleased that Knight has joined our strategic partnership
with Borse Berlin AG," said Matteo Cassina, President of Citadel European
Execution Services, a division of Citadel Securities. "Knight and Citadel
have a history of successful collaboration in emerging trading platforms. We
look forward to working together in the European market and expanding
Equiduct's capabilities."

The transaction is expected to close by the end of June 2010.
