TEPPCO projects first full-year earnings before interest, taxes, depreciation and amortization (EBITDA) from the Chaparral and Quanah systems of approximately $16 million. All of the revenue associated with the acquired assets is either tariff or fee-based. The acquisition will be immediately accretive to income and cash flow.

Thacker, chairman and chief executive officer of the general partner of TEPPCO. “Over the last two years TEPPCO has announced more than $900 million in acquisitions, and we remain committed to completing accretive acquisitions of $300 million to $400 million in 2002.”

The Chaparral system is an 800-mile pipeline that extends from West Texas and New Mexico to Mont Belvieu, Texas. The pipeline delivers natural gas liquids (NGLs) to fractionators and existing TEPPCO storage in Mont Belvieu. The approximately 170-mile Quanah Pipeline is a NGL gathering system located in West Texas. The Quanah Pipeline begins in Sutton County, Texas, and connects to the Chaparral Pipeline near Midland, Texas. The pipelines are connected to 27 gas plants in West Texas and have approximately 28,000 horsepower of pumping capacity at 14 stations. The transaction also includes the San Andres facility in Andrews County, Texas – two underground NGL storage wells with 220,000 barrels of combined capacity. The assets will be operated and commercially managed by Duke Energy Field Services, LP (DEFS) under agreements with TEPPCO.

“As the parent company of the general partner of TEPPCO, DEFS is very excited about this acquisition,” said Jim W. Mogg, chairman, president and chief executive officer of DEFS and vice-chairman of the general partner of TEPPCO. “With DEFS’ significant gas processing capacity in West Texas and ownership in two fractionation plants in Mont Belvieu, DEFS is in a position to bring value to the acquisition. This should significantly benefit both TEPPCO and DEFS as we continue to provide quality service to producers in the Permian Basin area.”

The acquisition will initially be funded under TEPPCO’s bank credit facilities. TEPPCO is evaluating permanent financing alternatives.
