GULFSTREAM PIPELINE FULLY OPERATIONAL FOLLOWING KATRINA

TAMPA, Fla. -- Gulfstream Natural Gas System, L.L.C. reported Thursday that the natural gas pipeline is fully operational and is continuing to transport all supplies tendered to it by customers.

The 691-mile pipeline is receiving natural gas supplies from both offshore and onshore sources, however those natural gas supplies are at reduced levels. The pipeline facilities did not sustain any significant damage from Hurricane Katrina.

"Despite the fact that some natural gas supplies have been interrupted, Gulfstream has continued to flow all gas delivered to the pipeline," said Gulfstream Operations Vice President Al Taylor. "Gulfstream will increase its deliveries of natural gas into the Florida market as natural gas production is restored."

Placed into service in May 2002, the Gulfstream pipeline has the capacity to deliver 1.1 billion cubic feet of natural gas each day to serve Florida's growing energy needs. The pipeline is a joint development between Williams (NYSE: WMB) and Duke Energy (NYSE: DUK).
