Terra Futuros leveraging Orc Spreader for futures arbitrage on
BM&FBOVESPA

Sao Paulo, September 27, 2011 - Orc Group (SSE: ORC), a leading provider
of technology and services for the global financial industry, announced
today that Brazilian broker Terra Futuros will use Orc Spreader for
futures arbitrage on the BM&FBOVESPA exchange as well as inter-market
arbitrages between the BM&FBOVESPA and other global exchanges. The order
was booked in Q3, 2011, and the contract is based on Orc's licensing
subscription model.

Terra Futuros will use Orc Spreader, a server-based trading solution
designed for spread trading and other arbitrages. Terra Futuros will
initially use Orc Spreader for commodities arbitrage opportunities on
the BM&FBOVESPA as well as for arbitrages between the BM&FBOVESPA and
several exchanges in the US and Europe.

Ruben Guerrero, Brazil Sales Director at Orc, notes, “We are seeing
continued interest from Brazilian traders for advanced, low-latency
solutions to trade both the BM&FBOVESPA and other exchanges globally.
Terra Futuros has developed a reputation for aggressively addressing the
market, and with Orc they will be able to trade faster and grow their
business quickly as they access new markets and trade more products.”

Francis Palmgren, Managing Director at Terra Futuros, comments, “We
required a trading solution that was fast, scalable, and most
importantly, easy to set up. Orc met all of our requirements. The
Brazilian markets have a great potential. Trading these markets requires
a solution like Orc's. After using Orc for some time, we have noticed a
significant improvement in the speed of our arbitrage and spread
strategies.”

Orc Spreader is built on the multi-threaded, server-based algorithmic
trading engine Orc Liquidator. It includes trading logic designed for
spread traders and pairs traders. The server-based architecture of Orc
Spreader, including an extremely high-performance trading engine, can be
co-located at exchanges resulting in the lowest possible latency. Orc's
extensive low-latency connectivity to over 100 markets around the world
is also available to users.
