Kansas City, MO (November 24, 2009) – Inergy, L.P. (Nasdaq: NRGY) announced today that it has closed a new $525 million four-year senior secured revolving credit facility. The new credit facility replaces Inergy’s old facility that was due to mature in November 2010. The syndicated transaction was led by J.P. Morgan Securities, Inc.; Wells Fargo Securities, LLC; and Banc of America Securities, LLC, each serving as joint lead arranger and joint bookrunner. The credit facility includes a diverse group of 18 banks and was well supported by our existing bank relationships as well as several new lenders to Inergy. JP Morgan Chase Bank, NA will serve as the administrative agent.

“We are pleased to have closed on this new credit facility as it further enhances Inergy’s financial strength and flexibility. We appreciate the institutions that participated in the transaction and the confidence they have in Inergy in a period of focused capital allocation,” said Brooks Sherman, Executive Vice President and CFO of Inergy. “The combination of our strong balance sheet and this expanded capacity positions us to continue the execution of our growth strategy on behalf of our unitholders.”

The credit facility consists of a $75 million revolving working capital line of credit and a $450 million revolving general partnership line of credit and includes an expansion option of up to $100 million. The credit facility may be used for general partnership purposes including the refinancing of existing indebtedness, the financing of acquisitions and capital expenditures, and the financing of working capital needs. The credit facility matures in November 2013, and amounts outstanding will bear interest at variable interest rates. The Company currently has approximately $76 million outstanding under the new credit facility.
