Press Release

DALLAS & HOUSTON--(BUSINESS WIRE)--April 10, 2000--Science Applications International Corporation (SAIC) and the Halliburton Company (NYSE: HAL) announced today their intent to form a venture which will provide Web-based portals tailored to enhance the way upstream exploration and production (E&P) professionals are hosted in a high performance, networked technical environment.

"Wealth creation in the E&P industry is based on a series of investment decisions," said Dick Cheney, chairman and chief executive officer of Halliburton, "each of which calls for a unique set of tools, information and professional experience. Many of the pieces of these solutions have been available for some time. This venture will use the Internet to provide the backbone for bringing them together in real time to increase investment returns."

The new venture will support a collaborative approach to E&P decisions through Knowledge Service Providers (KSPs). KSPs provide an integrated set of software applications, data integration and collaboration capabilities, shared among communities of practice formed around the key decision points in the life of oil field assets. Through KSPs, it will be possible to extend these communities dynamically beyond corporate boundaries to include partners as needed. The key enabling technologies are a reliable, secure, high-bandwidth communications infrastructure coupled to scaleable, high performance software and computing facilities.

"When fully operational, the KSP will allow teams of energy industry scientists, engineers, and investment analysts to work together more effectively by collaborating and exchanging information interactively over a secure network," said Dr. J. Robert Beyster, chairman and chief executive officer of SAIC.

"This venture will pioneer the transformation of the E&P industry's operational processes. No longer will professionals have to come together geographically in order to collaborate. The day of virtual 'infostructures' has arrived," said Robert P. Peebler, president and chief executive officer of Landmark Graphics Corporation, a subsidiary of Halliburton.

"Our energy customers need a system that provides value and reduces costs. We believe our venture with SAIC will bring those attributes to the marketplace," Peebler added.

Venture to leverage existing network

The venture will be headquartered in Houston, Tex. SAIC's Advanced Network eXchange(TM) (ANX(R)) will provide the platform for communications services.

"This is consistent with our strategy of expanding the ANX(R) network into other markets beyond the automotive industry. With these technical applications being at the heart of the E&P value chain, they need the high performance, reliable and secure connectivity that the ANX(R) network provides," said John E. Glancy, head of SAIC's e-commerce business.

Lane Sloan, head of SAIC's Energy Sector, noted, "Providing data integration capabilities is an ultimate objective which should provide high value to E&P customers. Landmark's expertise in E&P software applications and project data management, and SAIC's strengths in application interpretation and data warehousing are being brought together to enable the high level integration of multiple data sources covering both technical and business data."

The concept of a workflow-centric portal will be the foundation for transforming the E&P operational processes. The KSP structure will provide a layered set of capabilities ranging from Internet access of E&P information sources to technical application hosting, data integration services, and collaboration facilities. Its open architecture will enable a wide array of applications and services from a broad spectrum of providers.
