Item 8.01 Other Events

On June 26, 2009, we announced that our Oklahoma Natural Gas Company division filed an application with the Oklahoma Corporation Commission seeking a $66.08 million increase in that utility's base rates. We have not had a base rate adjustment in Oklahoma since July 2005.

In testimony prepared for the rate case, Oklahoma Natural Gas Company President Roger Mitchell pointed out that several expenses that now appear as separate line-item charges on customers' bills would be moved into base rates under this proposal, effectively reducing the requested rate increase to a net amount of $37.6 million.

In accordance with Oklahoma law, the Oklahoma Corporation Commission will have 180 days to consider Oklahoma Natural Gas Company's proposed rate changes.
