BOSS encompasses all of the enabling technology required to run the business side of a telephone company, and is a critical element in ICO's planned year 2000 services launch. The infrastructure developed by CSC will enable ICO to bill for services, support service partners, allow for fraud management and provide a repository of call data for use by other ICO functions. By late 1999, BOSS is scheduled to participate in ICO systemwide testing.

The deal with CSC is the last major ICO infrastructure contract to be awarded and is a significant milestone in the company's preparations to offer full commercial service in the year 2000.

"This partnership demonstrates ICO's commitment to work with the best in any field," said Olof Lundberg, ICO's chief executive officer. "It is not a typical client-vendor engagement - it is a partnership to maximize our collective strengths. CSC's systems integration skills and understanding of operations management will contribute towards ensuring a cost-effective system. They compliment ICO's in-house expertise in service definition and delivery. CSC is very much our partner of choice."

"This contract is ground-breaking in many ways," said Van B. Honeycutt, CSC chairman, president and chief executive officer. "The unique technology we will develop with ICO will manage the entire life-cycle relationship of a subscriber, from service initiation to customer care. And our relationship with ICO goes well beyond the traditional obligations of client and supplier to a true partnership."

Contract work will be performed from CSC's European headquarters at Farnborough, England, and at ICO's offices in Hammersmith, England.

ICO's services will be based on a new generation of pocket-sized mobile phones that will allow users to make and receive calls at any time, anywhere in the world. The handsets will be dual mode, capable of working on satellite, cellular and PCS networks. Using these handsets, customers will be free to roam between ICO and mobile networks globally. If no cellular network is available, the handset will "roam" to ICO's satellite network to offer customers unrestricted mobility and accessibility.

Affordable services will be available to a wide range of users, from people living and working in remote, rural areas to international business travelers. In addition, ICO will offer services to the road transport, maritime and aeronautical sectors.

CSC had $6.6 billion in revenues for the 12 months ended April 3, 1998. Headquartered in El Segundo, Calif., the company has nearly 45,000 employees in 700 offices worldwide and provides clients with a wide range of professional services, including management consulting, information systems consulting and integration, and operations support.
