Jakob Håkanson Vice President Investor Relations OM Gruppen BRIDGE AND ORC SOFTWARE FORM JOINT VENTURE Offer Online Trading Services for the Exchange-Traded Derivatives and Equities Markets NEW YORK, Apr. 26 — Bridge Information Systems, Inc (BRIDGE) and Orc Software AB (Publ) (ORC), a subsidiary of OM Technology within the OM group, have formed a joint venture to develop and distribute online trading services to the global derivatives and equities markets. Leveraging the distribution capacity of BRIDGE’s more than 300,000 subscribers and ORC’s 20 market interfaces, the joint venture is poised to offer the largest broker neutral transaction network for futures, options and equities. The service will be available in the third quarter of this year. Using the partners’ proven technologies, institutional investors will be able to route orders via brokers for execution on electronic exchanges, either through BRIDGE services delivered via SAVVIS’s global IP network and/or SAVVIS’s Internet service. The joint venture is positioned to capitalize on increased volume in derivatives trading and on the growing importance of information technology in this market segment. BRIDGE has more subscribers in North America than any other market data provider and has impressive distribution on a global scale as well, said Magnus Karlsson Böcker, President of OM Technology. Aligning ourselves with BRIDGE brings the potential for significant market penetration from day one. Order entry will be integrated with BRIDGE’s value-added content of more than 2,500 contributors and more than 450 news and research sources. Joining forces with ORC, a premier online trading technology company, to deliver transaction services to our subscribers is a logical step for BRIDGE, said Thomas M. Wendel, BRIDGE Chairman and CEO. Users will benefit from ORC’s market interfaces and high-end trading and risk management products. The joint venture will offer the largest broker-neutral order-routing network in the derivatives markets. Buy side users can select a broker from a drop-down menu in an order-entry application. An order management server at the broker accepts or rejects the order automatically and directs it electronically to the exchange. The joint venture will charge brokers a toll per contract or per share for each order they receive through the network.
