OTC Global Holdings selects Orc Trader for emissions trading

Leading independent interdealer broker selects Orc for its entry into
European markets.

Stockholm, SWEDEN, Thursday, December 16, 2010 - Orc Software (SSE:
ORC), the leading provider of technology and services for the global
financial industry, today announced that OTC Europe LLP, the European
arm of OTC Global Holdings, a leading independent interdealer broker in
OTC commodities, has selected Orc Trader for its over-the-counter carbon
options trading operations. The order was booked in Q4, 2010, and the
contract is based on Orc's licensing subscription model.

Brett Genus, Emissions options broker, OTC Europe LLP said, “When
working in a market which is efficient and also an emerging market such
as emissions where there often is irregular and therefore sometime
unreliable price data on the exchange, no system offers better
flexibility and robustness than Orc Trader. We also appreciate Orc's
exceptional IT support network and the professional resources they
provide. Equally impressive is the deep industry and product knowledge
demonstrated by the Orc team members.”

OTC Global Holdings LP now expands its successful business model into
Europe with a concentration on Energy markets. OTC will use Orc as a
thin brokerage GUI for theoretical calculations, options pricing and
volatility management. The solution is tailored for trading carbon on
ECX / ICE, the most liquid, pan-European platform for carbon emissions
trading, with its futures contract based on the underlying EU Allowances
(EUAs) and Certified Emissions Allowances (CERs), attracting over 80% of
the exchange-traded volume in the European market.

“Adding OTC Europe LLP to our client portfolio has strategic
significance to Orc, because we recognize the huge potential in the
energy sector,” said Jon Freebody, Vice President Sales, UK and France,
Orc Software. “We can see this becoming a major force as liquidity grows
and the sector becomes more electronic. Orc also benefits from gaining
an insight into OTC Global Holdings, a dynamic, specialist broker with a
vast network of more than 175 brokers in North America and Europe.”

The Orc Trading solutions are used by leading financial firms worldwide
for market making, volatility trading and high-frequency trading.
Together with access to all major cash and derivatives markets and a
network of brokers, this is truly an unmatched offering. Orc Trading is
