INDUSTRY LEADERS FORM INTEGRES TO TRANSFORM HEAVY FREIGHT SHIPPING INDUSTRY WITH TIME-GUARANTEED AND AFFORDABLE DELIVERY
United Airlines, American Airlines, Roadway Express, Unisys Corporation, and UTi Worldwide Inc. Form Strategic Equity Partnership To Expedite Heavy Freight Delivery

Rancho Cordova, Calif.—Company officials today announced the formation of Integres, Inc., a groundbreaking venture designed to transform the $50 billion domestic expedited and international heavy freight transportation industry. Combining the capabilities of some of the largest names in the transportation industry—United Airlines (NYSE:UAL), American Airlines (NYSE:AMR), Roadway Express, (Nasdaq: ROAD), and UTi Worldwide Inc. (Nasdaq: UTIW)—Integres is the first company to provide an end-to-end integrated freight service that uses Web-based portal and other technologies to revolutionize the delivery of freight. The Integres solution will integrate strategic transportation providers with leading-edge transportation management technology from Unisys Corporation (NYSE: UIS). As a result of this venture, shippers can now compete in the New Economy with predictable, time-definite and affordable service and transportation providers can meet shipper demands with this breakthrough new service.

The freight industry is characterized by fragmented providers, limited services, and no end-to-end solution, making the process expensive and prone to errors. In addition, customer expectations for speed and reliability continue to rise, spurred by the digital economy. Integres brings extraordinary value to small and medium-sized shippers by providing global access, competitive prices, and Web-based logistical support to easily and conveniently schedule shipments. In addition, Integres brings value to transportation providers by extending their product lines and providing complete logistics management through the Integres turnkey solution. Integres links all transportation partner order management and back office systems, allowing them to conduct business electronically and reach more customers. The Integres solution benefits all transportation providers, affiliates and customers through more efficient communication, ease of use, and reduced errors.

"The cargo industry is experiencing a rapid evolution," said James Hartigan, president and CEO of Integres. "Businesses are increasingly looking for shipping solutions that leverage the benefits of e-Commerce while protecting margins and enhancing their existing relationships. Integres levels the playing field by helping our partners and affiliates compete for, and win, in the full-service global cargo market."

Hartigan, an industry veteran, was formerly the vice president of United Airlines Cargo. He has spent 35 years in the transportation industry, and has assembled a team of seasoned executives from top logistics and freight forwarding companies.

"Shippers are looking for a full range of expedited services and e-Commerce-enabled business solutions. Integres offers us the opportunity to broaden our expedited domestic and international service offerings for current customers," said Mike Wickham, chairman and chief executive officer of Roadway Express. "It will do so through a product line that provides access to the world's leading cargo carriers and freight movers. Additionally, with Roadway Express serving as Intregres' primary North American ground carrier, we will have a new channel to additional market and business development opportunities."

"We are eager to embark on the formation of this new venture, Integres," said Doug Hacker, executive vice president and chief financial officer of United Airlines and president of United NewVentures. "By bringing together leading industry technology from Unisys, along with the partnership of asset-based carriers, such as United, American and Roadway, as well as a leading freight forwarder, UTi, we will be able to offer a superior product to small and medium-sized shippers with a higher level of service and competitive pricing in this market."

"Our e-Commerce strategy supports the exploration of a number of electronic platforms for doing business with our customers. We believe that an electronic market in airfreight is inevitable, and are pleased to announce our participation in Integres," said Dave Brooks, president of AA Cargo. "Integres will provide a breakthrough in service never before possible for the small and medium-sized shipper who can gain Web access to integrated transportation services from the industry's top providers."

Integres strategic partners, United Airlines and American Airlines, provide access to a broad worldwide combination passenger/cargo network. Roadway Express is the primary less-than-truckload partner, providing sales support and operational fulfillment. Unisys provides access to its back-end freight operations systems along with integration and hosting services for all Integres systems. UTi Worldwide Inc., a global logistics service provider and customs broker, is the international partner. Integres will allow its partners and affiliates to compete with integrators via instant access to critical logistics management resources, including dynamic pricing, routing and tracking information, reporting, payment and claims processing.
