The agreement also includes preferred provider status for CSC, which will enhance Global Crossing's IT infrastructure through joint development of SAP, Customer Relationship Management (CRM), and Web-based billing systems. Global Crossing is also exploring outsourcing to CSC its applications programming and desktop support , as well as opportunities to develop advanced consumption-based billing systems.

The third major element of the alliance is a joint marketing arrangement under which the companies plan to deliver integrated solutions to multinational organizations over a fully managed, global IP infrastructure shared between Global Crossing and CSC. Using this shared network, Global Crossing and CSC would team to provide scaleable network services and dedicated point-to-point data transport services, along with the full range of CSC's IT services and product offerings, including e-business solutions.

Honeycutt. "Our complementary strengths combine to provide customers with the most advanced, secure, scalable and fully integrated IT and network solutions available anywhere."

"Our alliance creates a powerful combination - the premier global IT integrator with the world's most extensive fiber-optic network," said Global Crossing Chief Executive Officer Tom Casey. "We look forward to calling jointly on customers in financial, government, media, entertainment and other global enterprises to discuss how we can develop the fully managed global solutions that this combination allows us to deliver."

In the initial phase of the alliance, CSC will implement its Integrated Global Network, which will connect CSC facilities and clients worldwide, on the Global Crossing Network. Deployment of CSC's internal network onto Global Crossing's IP backbone will begin during the first quarter of 2001 at CSC offices and data centers in Newark, Del.; Falls Church, Va.; Maidstone, UK; Copenhagen, Denmark; and Sydney, Australia.

CSC and Global Crossing plan to integrate their network management services using Global Crossing to manage the wide area network (WAN), and CSC's local area network (LAN) management centers to offer end-to-end managed solutions.
