Orc announces support for Turquoise Derivatives

Stockholm, SWEDEN, Friday April 15, 2011 - Orc Software (SSE: ORC), the
leading provider of technology and services for the global financial
industry, today announced connectivity to Turquoise Derivatives.
Turquoise Derivatives is the first Multi-lateral Trading Facility (MTF)
in Europe to offer trading in pan-European derivatives.

“Turquoise Derivatives is an innovative initiative in the European
derivatives markets, which will challenge the current market structure
and create new opportunities for our customers,” said Lee Griggs,
President EMEA, Orc Software. “A multi-listed environment is interesting
for both market makers and high frequency trading firms and we believe
it is essential to support Turquoise Derivatives from the first day of
trading.”

Turquoise Derivatives uses the latest SOLA platform, a technology
already covered by Orc. In addition, with Orc Hosted, Orc's fully
managed trading infrastructure, customers can quickly be operational in
Orc's co-located hosting facility, reducing requirements for internal IT
projects.

“Orc is an acknowledged leader in derivatives trading technology, so it
is great news that they will provide access to Turquoise Derivatives
right from the start,” said Natan Tiefenbrun, Commercial Director,
Turquoise. ”As we move to the new trading platform and introduce the
concept of multi-listed derivatives in Europe, Orc's commitment to our
development will give our clients confidence that we can develop a
liquid market with a diverse group of participants.”

Turquoise Derivatives is expected to become the first Multi-lateral
Trading Facility (MTF) in Europe to offer derivatives trading, starting
a new era in Europe for multi-listed derivatives. With multi-listed
derivatives, the same or economically equivalent derivative contracts
are traded over two or more markets.
