Overland Pass Pipeline Company LLC

On May 3, 2006, ONEOK Partners, L.P. entered into an agreement with a subsidiary of Williams (NYSE: WMB) to form a joint venture called Overland Pass Pipeline Company, L.L.C.

The $575 million to $590 million, 760-mile natural gas liquids project originates in Opal, Wyo., and terminates near Conway, Kan., at one of the nation’s primary natural gas liquids supply and storage hubs. The natural gas liquids pipeline travels through 23 counties in three states: five in Wyoming, six in Colorado and 12 in Kansas. The pipeline is designed to transport approximately 110,000 barrels per day with the ability to expand capacity to 255,000 barrels per day with additional pump facilities.

In early October, natural gas liquids began flowing into the Overland Pass Pipeline from Echo Springs, Wyo., to the Mid-Continent region at a rate of approximately 30,000 bpd. The remaining portion of the pipeline, from Opal to Echo Springs, is substantially complete and scheduled for startup during the fourth quarter 2008.

The Williams Companies, Inc. has dedicated approximately 60,000 bpd of its NGL production to the Overland Pass Pipeline. In addition, agreements have been reached for supply commitments of up to an additional 80,000 bpd, and additional agreements are being negotiated.

In conjunction with Overland Pass, ONEOK Partners has also completed much of the construction on $230 million to $240 million of projects that increase existing NGL fractionation and distribution pipeline capacity.
