July 24, 2007

Partnership to Organize Around Natural Gas and Natural Gas Liquids Operations

TULSA, Okla., July 24, 2007 /PRNewswire-FirstCall via COMTEX News Network/ --

ONEOK Partners, L.P. (NYSE: OKS) announced a series of organizational changes within the partnership, and ONEOK, Inc. (NYSE: OKE) announced the creation of a new organization, technical and corporate services.

Pierce H. Norton II, 47, has been promoted to executive vice president - natural gas, responsible for leading the partnership's natural gas segments.

Terry K. Spencer, 48, has been promoted to executive vice president - natural gas liquids, responsible for leading the partnership's natural gas liquids segments.

Both Norton and Spencer will continue to report to John W. Gibson, president and chief executive officer of ONEOK Partners. The promotions are effective immediately.

Beginning in the third quarter, the partnership will report its financial results in four segments: two in natural gas -- gathering and processing, and natural gas pipelines; and two in natural gas liquids -- natural gas liquids gathering and fractionation, and natural gas liquids pipelines.

"These changes -- around the natural gas and natural gas liquids businesses -- will provide us with a sharper focus and more clarity as we operate and grow the partnership, especially as we complete more than $1.5 billion of previously announced internal growth projects over the next three years," said John W. Gibson, president and chief executive officer of ONEOK Partners. "The change also reflects the increasing scale of our natural gas liquids business, which has grown significantly since 2005 and will expand even more as we integrate the recently announced Kinder Morgan acquisition into the natural gas liquids pipelines segment and complete our growth projects."

In addition, Stephan R. Guy, 52, becomes senior vice president, technical and corporate services for ONEOK and ONEOK Partners, with responsibilities for measurement, health, safety and environment, procurement and real estate, reporting to James C. Kneale, president and chief operating officer of ONEOK, Inc. Previously, Guy was president of pipeline services at ONEOK Partners.

    Reporting to Norton in the partnership's natural gas segments are:

    -- Robert F. Martinovich, 49, who has been hired as president of natural
       gas gathering and processing, the position formerly held by Norton.
       Martinovich joins ONEOK Partners from DCP Midstream, LLC, where he has
       held a variety of executive management positions.  In addition, Craig
       Forsander, 42, has been promoted to vice president of natural gas
       gathering and processing operations, reporting to Martinovich.
       Forsander was previously manager of pipeline operations in the
       partnership's gathering and processing segment;
    -- Kent Shortridge, 40, who becomes president of natural gas pipelines,
       which will now include the partnership's interstate and intrastate
       natural gas pipelines and storage.  He was president of the
       partnership's pipelines and storage and interstate natural gas
       pipelines segments; and
    -- Michel Nelson, 59, who remains senior vice president of natural gas
       pipeline operations.


Reporting to Spencer in the partnership's natural gas liquids segments are:

    -- Sheridan Swords, 38, who is promoted to president of natural gas
       liquids gathering and fractionation, and was previously vice president
       of exchange services in the partnership's NGL segment.  Spencer
       previously held this position;
    -- Roger Thorpe, 40, who is promoted to president of natural gas liquids
       pipelines and was previously vice president of operations in the
