Enterprise and Duncan Energy Announce Organizational Changes; Elect Teague as Director and Chief Commercial Officer

The general partners of Enterprise Products Partners L.P. (NYSE:EPD) and Duncan Energy Partners L.P. (NYSE:DEP) today announced organizational changes to their commercial management teams. A. J. "Jim” Teague, executive vice president, was elected as a director to the respective boards of the general partners and as chief commercial officer responsible for managing all of the commercial businesses of the partnerships. Teague will continue to report to Michael A. Creel, president and chief executive officer of Enterprise. Teague joined Enterprise in 1999 as executive vice president through the partnership’s acquisition of Shell Oil Company’s midstream energy business in Louisiana and Mississippi. Since that time, Teague has been responsible for Enterprise’s natural gas liquids ("NGL”) businesses and, more recently, developing its natural gas marketing group. Prior to joining Enterprise, Teague was a member of the senior management teams at affiliates of Shell Oil Company, MAPCO Inc. and Dow Chemical Company. "On behalf of the board of directors of the general partners of Enterprise and Duncan Energy, I am pleased to announce Jim Teague’s election as a director and the chief commercial officer of Enterprise,” said Creel. "Jim has a wealth of knowledge of the midstream energy business and has been an integral part of Enterprise’s success over the past nine years.” "At this time, we are also making changes to Enterprise’s commercial organization to make it more consistent with our value chain approach to conducting business. With this realignment, the management of Enterprise’s commercial businesses will now be organized into four reporting lines, each of which either form an integrated value chain or have complementary characteristics. The executives managing these businesses will report to Jim Teague. We believe these changes will be beneficial as we work to maximize the economic utilization of our $16 billion portfolio of midstream energy assets.” Enterprise’s regulated and offshore assets will be managed by James H. Lytal, executive vice president. In addition to Lytal’s existing responsibility for all of Enterprise’s regulated natural gas pipeline and storage assets and offshore businesses, he will assume responsibility for over 10,500 miles of regulated NGL pipelines. James M. Collingsworth, senior vice president, will continue to be directly responsible for Enterprise’s regulated NGL pipelines, including the Mid-America, Seminole and Dixie pipelines, and will report to Lytal. The partnerships’ unregulated NGL businesses will be managed by Thomas M. Zulim, senior vice president. Zulim is returning to the NGL business group after spending the last four years managing the human resources organization for privately held EPCO, Inc., which employs all of the personnel that manage, operate and administer Enterprise’s assets. In his new role, Zulim will lead the partnerships’ natural gas gathering and processing business and the NGL fractionation, storage, unregulated NGL pipeline and marketing businesses. This group includes certain Enterprise natural gas gathering systems that integrate with its natural gas processing and downstream NGL value chain, such as the San Juan and Permian natural gas gathering systems. Prior to leading the human resources group, he served as the commercial attorney supporting the unregulated NGL businesses and has also previously managed the partnership’s NGL fractionation business. The unregulated natural gas businesses will be managed by Christopher R. Skoog, senior vice president. He will have responsibility for the partnerships’ non-regulated and intrastate natural gas pipeline and storage businesses, as well as natural gas marketing. This business group includes Enterprise’s Texas Intrastate and Acadian pipeline systems and the Wilson natural gas storage facility in Texas. Petrochemical services will continue to be managed by G.R. "Jerry” Cardillo, vice president. This business group includes the partnerships’ butane isomerization, propylene fractionation and pipeline and octane additive businesses. These organizational changes will not have an effect on the reportable business segments of the partnerships.
