News Release
Jan. 12, 2001


TULSA, Okla., January 12, 2001 C CMS Energy Corporation’s (NYSE:CMS) CMS Field Services, Inc. unit and Duke Energy Field Services (DEFS) today announced that they have acquired certain assets from one another that increase the regional assets and services offered by both companies.

CMS Field Services acquired from DEFS certain natural gas gathering and condensate measuring and transportation assets onshore and offshore Louisiana, and DEFS acquired from CMS Field Services certain natural gas gathering assets located in Oklahoma and Kansas. The assets that were acquired are more strategically located for each company. The transaction closed December 20, 2000.

"This transaction makes both strategic and economic sense for CMS Energy," said Tim Young, senior vice president for CMS Field Services. "CMS Energy’s acquisition of the Panhandle Eastern Pipe Line Company and Trunkline Gas Company natural gas pipeline systems from Duke Energy in 1999 made these DEFS Gulf Coast assets a strategic fit for CMS Energy. The assets we received in the transaction will give CMS Energy increased opportunities to offer additional services to existing and potential shippers on CMS owned pipelines in the Gulf Coast region."

CMS Field Services acquired from DEFS 10 offshore gas gathering laterals, a one-third ownership in the Atchafalaya Pipeline System and complete ownership in a condensate measuring facility located near Patterson, La.

The 10 offshore gas gathering laterals are connected to two CMS Energy owned and operated offshore pipelines: the CMS Trunkline Gas Company’s Terrebonne system and the CMS Sea Robin Pipeline Company system. The Atchafalaya Pipeline is a 39-mile condensate pipeline that receives condensate from the Terrebonne system. The Patterson measurement facility measures condensate transported to Atchafalaya Pipeline.

Assets acquired by DEFS consist primarily of two Midcontinent natural gas gathering systems; the Bradshaw Gathering System in Kansas and the Roaring Creek Gathering System in Oklahoma.

Other assets to be acquired from CMS Field Services include the Miles Hampton and Ulysses systems in Kansas and the Christmas Lateral in South Texas.

"These assets are a great strategic fit with our assets in the area, as they will specifically provide supply to plants with existing capacity" said Michael Bradley, senior vice president, DEFS’ northern division. "This asset exchange supports our growth strategy of optimizing and rationalizing assets and allows us to offer more service options and flexibility to our customers."

DEFS was formed by combining the Duke Energy and Phillips Petroleum natural gas gathering and processing businesses. Duke Energy owns approximately 70 percent of the joint venture and Phillips Petroleum owns about 30 percent. More information is available about the company at
