SHANGHAI, China, July 12, 2005 - Intergraph Corporation and China Petroleum and Chemical Corporation (SINOPEC), the largest petrochemical producer and crude oil refiner in Asia, have entered into a long term strategic relationship. The relationship allows SINOPEC subordinate engineering companies unlimited access to the majority of Intergraph Process Power & Marine division engineering and design software including SmartPlant? and PDS? applications. The strategic relationship provides flexible software use to improve competitive advantage while reducing administrative and project costs. Intergraph will supply the software along with technical support and consulting to a number of SINOPEC engineering subsidiaries throughout China.

“A key part of this long term strategic relationship is the increased levels of support and services from Intergraph that are available to the subordinate engineering companies of China Petroleum and Chemical Corporation (SINOPEC). The strategic relationship will significantly reduce project execution costs by allowing SINOPEC to meet its increasing business demands. It will consolidate and enhance the competitive advantage in the international and domestic market for the SINOPEC subordinate engineering companies,” SINOPEC officials commented. “Intergraph's leading position in the Chinese petrochemical industry is firmly entrenched and further confirmed by the establishment of this long term strategic relationship.”

The SINOPEC subordinate engineering companies have been using Intergraph software for a dozen years and the new strategic relationship will allow all parties to obtain long term benefits.

“As the leading technology provider to the petrochemical industry, Intergraph’s new strategic relationship with SINOPEC further advances our strong presence in the Chinese market,” said Gerhard Sallinger, president, Intergraph Process, Power and Marine.
