ONEOK Partners Increases Quarterly Distribution





TULSA, Okla. - July 25, 2013 - The board of directors of the general partner of ONEOK Partners, L.P. (NYSE: OKS) today increased the partnership’s quarterly cash distribution by 0.5 cents to 72 cents per unit from 71.5 cents per unit, effective for the second quarter 2013, resulting in an annualized cash distribution of $2.88 per unit.  The distribution is payable Aug. 15, 2013, to unitholders of record as of Aug. 5, 2013.





“This distribution increase further demonstrates our commitment to deliver value to our unitholders,” said John W. Gibson, chairman and chief executive officer of ONEOK Partners.  “We expect our previously announced investments of approximately $4.7 billion to $5.2 billion for natural gas and natural gas liquids growth projects through 2015 to allow us to continue increasing unitholder distributions.”





ONEOK Partners has increased its distribution by approximately 80 percent since April 2006, when a wholly owned subsidiary of ONEOK, Inc. (NYSE: OKE) became the sole general partner.

(pronounced ONE-OAK) (NYSE: OKS) is one of the largest publicly traded master limited partnerships, and is a leader in the gathering, processing, storage and transportation of natural gas in the U.S. and owns one of the nation’s premier natural gas liquids (NGL) systems, connecting NGL supply in the Mid-Continent and Rocky Mountain regions with key market centers.
