Orc is one of the first to provide native market access through
BM&FBOVESPA's new low-latency framework

Chicago & São Paulo, Wednesday, December 8th, 2010 - Orc Software (SSE:
ORC), a leading provider of technology and services for the global
financial industry, announced today complete connectivity to Brazil's
BM&FBOVESPA exchange for futures, options and equities instruments, and
that Orc will be one of the first companies to support BM&FBOVESPA's new
market data framework delivering higher performance and reliability.

Orc, as one of the first software providers to support BM&FBOVESPA's new
market data framework, known as the BM&FBOVESPA UMDF and based on the
global FAST market data messaging standard, will be able to provide
clients with the best trading experience to BM&FBOVESPA. This allows Orc
clients to enjoy full, high performance native market access to this
important and growing exchange with the performance benefits that
BM&FBOVESPA's market data enhancements provide.

The FAST protocol, based on the industry standard FIX protocol, has
rapidly become the preferred choice for delivering market data quickly
and reliably. Deployment of FAST market data at the exchange has
resulted in a 50% reduction in bandwidth on the BOVESPA segment and a
200% reduction in bandwidth on the BM&F segment. This lets firms handle
more market data quickly and easily without network bandwidth delays.

Ruben Guerrero, Strategic Partnerships Manager at Orc Software,
comments, “Brazil is a strategic market for Orc, and BM&FBOVESPA is
growing rapidly. Our clients demand the best possible trading experience
when trading in Brazil. With our native market access to BM&FBOVESPA and
support for its new market data distribution protocol, our clients will
be able to trade more instruments, more quickly and take advantage of
the opportunities available in this market.”

Marcio Castro, IT Director for Matching Systems at BM&FBOVESPA, notes,
“BM&FBOVESPA's adoption of FAST for market data was an important step
for our exchange. We are happy to see Orc delivering a powerful
connection to our exchange taking advantage of this technology. We look
forward to adding new clients to our exchange that need the high
performance that BM&FBOVESPA and Orc can provide.”

Traders will be able to use Orc's connection to BM&FBOVESPA for
deploying sophisticated trading strategies including futures spread
trading, market making, volatility trading and other advanced
arbitrages. Using Orc's Liquidator server-based technology, firms can
co-locate at BM&FBOVESPA to minimize their latency. Clients can take
